The goal of the study was to outline the functional results after medialization thyroplasty with the titanium vocal fold medialization implant according to Friedrich. In the period of to , an external vocal fold medialization using the titanium implant was performed on 28 patients 12 women and 16 men. The patients were in the age range of 19 to 84 years.
Twenty-two patients had a paralysis of the left-side vocal fold, and six patients, of the right-side vocal fold. The respective data were statistically analyzed paired t test, Wilcoxon-test. All patients reported on improvement of voice, swallowing, and breathing functions postoperatively. Videostroboscopy revealed an almost complete glottal closure after surgery in all of the patients. All voice-related parameters showed a significant improvement.
An increase of the laryngeal resistance by the medialization procedure could be excluded by analysis of the pulmonary function test. The results confirm the external medialization of the vocal folds as an adequate method in the therapy of voice, swallowing, and breathing impairment attributable to an insufficient glottal closure.
The titanium implant offers, apart from good tissue tolerability, the. Medialized repair for retracted rotator cuff tears. The purpose of this study was to evaluate the functional outcomes of medialized rotator cuff repair and the continuity of repaired tendon in chronic retracted rotator cuff tears. Thirty-five consecutive patients were selected from cases that underwent arthroscopic rotator cuff repair for more than medium-sized posterosuperior rotator cuff tears between July and July performed with the medialized repair. All cases were available for at least 2 years of postoperative follow-up.
At the final follow-up, all clinical outcomes were significantly improved. The shoulder score also improved: Constant score, from Medialized repair may be useful in cases in which anatomic bone-to-tendon repair would be difficult because of the excessive tension of the repaired tendon and a torn tendon that does not reach the anatomic insertion.
Published by Elsevier Inc. Critically evaluate the published literature related to quadriceps tendon QT medial patellofemoral ligament MPFL reconstruction. Hamstring tendon HT MPFL reconstruction techniques have been shown to successfully restore patella stability, but complications including patella fracture are reported. Quadriceps tendon QT reconstruction techniques with an intact graft pedicle on the patella side have the advantage that patella bone tunnel drilling and fixation are no longer needed, reducing risk of patella fracture.
Stress fracture of the medial clavicle secondary to nervous tic. The clinical and radiological characteristics of swelling in the region of the medial clavicle may suggest the presence of a neoplastic or inflammatory lesion. This report describes a year-old man with a painful tumor-like lesion over the medial clavicle, which was found to be a stress fracture caused by a nervous tic resulting from mental stress. Anatomical and magnetic resonance imaging study of the medial Introduction: The medial collateral ligament of the ankle joint also known as the deltoid ligament, is a multifascicular group of ligaments.
It can be divided into a superficial and deep group of fibers originating from the medial malleolus to insert in the talus, calcaneus, and navicular bones. Wide variations have been noted in Medial shoe-ground pressure and specific running injuries. Foot balance was categorized into those which presented a higher lateral shod pressure LP than medial pressure, and those which presented a higher medial shod pressure MP than lateral pressure during the stance phase. A time-to-event model was used to compare differences in incidence between Trochleoplasty and medial patellofemoral ligament reconstruction for recurrent patellar dislocation.
Full Text Available We report a case of recurrent patellar dislocation with high-grade trochlear dysplasia which persisted despite two previous operations. Trochleoplasty and medial patellofemoral ligament reconstruction is required in patients with high grade trochlear dysplasia. UKA is a regularly used treatment for patients with medial osteoarthritis OA of the knee. UKA has a higher revision rate than total knee arthroplasty.
Intrinsic factors associated with medial tibial stress syndrome in Intrinsic factors associated with medial tibial stress syndrome in athletes: A large case-control study. Medial tibial stress syndrome MTSS is the most common lower-leg injury in athletes, and is thought to be caused by This paper considers the functional significance of the testosterone-dependent vasopressinergic neurons of the medial amygdala Ame in intermale aggressive behavior of rats.
Local microinfusion of vasopressin into the medial amygdala causes an increase in offensive behavior both in gonadally intact. Traumatic posterior root tear of the medial meniscus in patients with severe medial instability of the knee. To examine the incidence and diagnostic rate of traumatic medial meniscus posterior root tear associated with severe medial instability and to evaluate the effectiveness of pullout repair.
From to , 51 patients who underwent operation due to multiple ligament injuries including medial collateral ligament rupture were reviewed retrospectively. Postoperative magnetic resonance imaging MRI was performed, and if indicated, a second-look arthroscopic examination was conducted. Fourteen out of 51 patients were associated with severe medial instability. Seven patients were diagnosed with traumatic medial meniscus posterior root tear and underwent arthroscopic pullout repair. Five of them were missed at initial diagnosis using MRI. All showed complete healing of meniscus root on follow-up MRI and second-look arthroscopy.
Medial meniscus posterior root tear may occur in severe medial instability from trauma. It is a common mistake that surgeons may not notice on the diagnosis of those injuries using MRI. Therefore, a high index of suspicion is required for the diagnosis of medial meniscus posterior root tear in this type of injuries. The traumatic medial meniscus posterior root tear could be healed successfully using arthroscopic pullout repair technique.
The possibility of the medial meniscus posterior root tear should be considered in severe medial instability and arthroscopic pullout repair can be an effective option for treatment. Case series with no comparison group, Level IV. De estos, eran de origen hispano del lado mexicano de la frontera y del estadounidense.
Centralization of extruded medial meniscus delays cartilage degeneration in rats. Meniscus extrusion often observed in knee osteoarthritis has a strong correlation with the progression of cartilage degeneration and symptom in the patients. We recently reported a novel procedure "arthroscopic centralization" in which the capsule was sutured to the edge of the tibial plateau to reduce meniscus extrusion in the human knee.
However, there is no animal model to study the efficacy of this procedure. The purposes of this study were  to establish a model of centralization for the extruded medial meniscus in a rat model; and  to investigate the chondroprotective effect of this procedure. Medial meniscus extrusion was induced by the release of the anterior synovial capsule and the transection of the meniscotibial ligament. Centralization was performed by the pulled-out suture technique. Alternatively, control rats had only the medial meniscus extrusion surgery.
Medial meniscus extrusion was evaluated by micro-CT and macroscopic findings. Cartilage degeneration of the medial tibial plateau was evaluated macroscopically and histologically. By micro-CT analysis, the medial meniscus extrusion was significantly improved in the centralization group in comparison to the extrusion group throughout the study.
Both macroscopically and histologically, the cartilage lesion of the medial tibial plateau was prevented in the centralization group but was apparent in the control group. We developed medial meniscus extrusion in a rat model, and centralization of the extruded medial meniscus by the pull-out suture technique improved the medial meniscus extrusion and delayed cartilage degeneration, though the effect was limited.
Centralization is a promising treatment to prevent the progression of osteoarthritis. Published by Elsevier B. Fragmentation of the medial malleolus of dogs with and without tarsal osteochondrosis. Fragmentation of the medial malleolus of the tibia was found radiographically in 5 canine tarsi which did not have evidence of osteochondrosis of the medial trochlear ridge. An additional 5 tarsi were found where both medial malleolar fragmentation and osteochondrosis of the medial trochlear ridge were present.
Radiographic evidence of degenerative joint disease was present in 3 of 5 dogs with medial malleolar fragmentation alone, and 5 of 5 dogs with medial malleolar fragmentation and medial trochlear ridge osteochondrosis. Eight of the 9 dogs were Rottweilers. Considering the sites of occurrence of osteochondrosis in other species, the authors propose that medial malleolar fragmentation could be secondary to osteochondrosis of the medial malleolus.
Osteochondrosis of the medial malleolus has not been previously reported in dogs. Histological examination of the medial malleolar fragmentation was unavailable because surgery was not performed, therefore the hypothesis that the medial malleolar fragmentation is due to osteochondrosis was not proven.

Pero en nuestro competitivo mundo actual, este Medial cortex activity, self-reflection and depression. Using functional magnetic resonance imaging, we investigated neural activity associated with self-reflection in depressed [current major depressive episode MDE ] and healthy control participants, focusing on medial cortex areas previously shown to be associated with self-reflection.
Both the MDE and healthy control groups showed greater activity in anterior medial cortex medial frontal gyrus, anterior cingulate gyrus when cued to think about hopes and aspirations compared with duties and obligations, and greater activity in posterior medial cortex precuneus, posterior cingulate when cued to think about duties and obligations Experiment 1.
However, the MDE group showed less activity than controls in the same area of medial frontal cortex when self-referential cues were more ambiguous with respect to valence Experiment 2 , and less deactivation in a non-self-referential condition in both experiments. Furthermore, individual differences in rumination were positively correlated with activity in both anterior and posterior medial cortex during non-self-referential conditions. These results provide converging evidence for a dissociation of anterior and posterior medial cortex depending on the focus of self-relevant thought.
They also provide neural evidence consistent with behavioral findings that depression is associated with disruption of positively valenced thoughts in response to ambiguous cues, and difficulty disengaging from self-reflection when it is appropriate to do so. Episodic reinstatement in the medial temporal lobe. The essence of episodic memory is our ability to reexperience past events in great detail, even in the absence of external stimulus cues. Does the phenomenological reinstatement of past experiences go along with reinstating unique neural representations in the brain?
And if so, how is this accomplished by the medial temporal lobe MTL , a brain region intimately linked to episodic memory? Computational models suggest that such reinstatement also termed "pattern completion" in cortical regions is mediated by the hippocampus, a key region of the MTL. Although recent functional magnetic resonance imaging studies demonstrated reinstatement of coarse item properties like stimulus category or task context across different brain regions, it has not yet been shown whether reinstatement can be observed at the level of individual, discrete events-arguably the defining feature of episodic memory-nor whether MTL structures like the hippocampus support this "true episodic" reinstatement.
Here we show that neural activity patterns for unique word-scene combinations encountered during encoding are reinstated in human parahippocampal cortex PhC during retrieval. Critically, this reinstatement occurs when word-scene combinations are successfully recollected even though the original scene is not visually presented and does not encompass other stimulus domains such as word-color associations.
Finally, the degree of PhC reinstatement across retrieval events correlated with hippocampal activity, consistent with a role of the hippocampus in coordinating pattern completion in cortical regions. Appearance of medial plica of the knee on MR images. To assess the appearance of the abnormal plica, a rare but important cause of knee pain, the authors have reviewed 1. Asymmetry in the medial wall of the patella pouch was seen in 17 of 17; 10 of 17 had a discernible edge, and four of 17 had sufficient fluid to surround the plica.
When sufficient intraarticular fluid was present, the plica was easily detected. Asymmetry in the medial wall of the patella pouch was a helpful MR characteristic to account for unexplained knee pain. Full Text Available We report a case of a chondral delamination lesion due to medial parapatellar plica friction syndrome involving the medial femoral condyle. This mimicked a torn medial meniscus in clinical and radiological presentation. Arthroscopy revealed a chondral delamination flap, which was debrided.
Diagnosis of chondral lesions in the knee can be challenging. Clinical examination and MRI have good accuracy for diagnosis and should be used in tandem. Early diagnosis and treatment of chondral lesions are important to prevent progression to early osteoarthritis. Modified tension band wiring of medial malleolar ankle fractures. Twenty-two displaced medial malleolar ankle fractures that were treated surgically using the modified tension band method of Cleak and Dawson were retrospectively reviewed at an average follow-up of 25 months.
The technique involves the use of a screw to anchor a figure-of-eight wire. There were no malreductions and all fractures healed. Problems with the technique included technical errors with hardware placement, medial ankle pain, and asymptomatic wire migration. Despite this, modified tension band wiring remains an acceptable method for fixation of selected displaced medial malleolar fractures.
It is especially suited for small fracture fragments and osteoporotic bone. Radiographic anatomy of the medial coronoid process of dogs. Mediolateral, flexed mediolateral, mediocaudal-laterocranial 15 degrees oblique extended and supinated mediolateral , and craniolateral-caudomedial 20 degrees to 30 degrees oblique radiographs of 16 elbow-joint specimens were produced to study the radiographic anatomy of the medial coronoid process.
On the mediolateral view, the cranial point of the coronoid process was at the level of the distal one-third of the radial epiphysis. Degree of superimposition of the proximal radius and ulna determined how the medial coronoid process was projected on the radiographs. Mediocaudal-laterocranial oblique radiographs best showed the cranial outline of the medial coronoid process with moderate superimposition of the proximal radius and ulna.

A three-year-old, female Border Collie was successfully treated for an isolated, torn, medial meniscus by arthroscopic meniscal tear resection. The dog returned to agility competition without recurrence of lameness. The name given to this condition refers to pain on the posteromedial tibial border during exercise, with pain on palpation of the tibia over a length of at least 5 cm.
Histological studies fail to provide evidence that MTSS is caused by periostitis as a result of traction. It is caused by bony resorption that outpaces bone formation of the tibial cortex. Evidence for this overloaded adaptation of the cortex is found in several studies describing MTSS findings on bone scan, magnetic resonance imaging MRI , high-resolution computed tomography CT scan and dual energy x-ray absorptiometry. The diagnosis is made based on physical examination, although only one study has been conducted on this subject.
The prevalence of abnormal findings in asymptomatic subjects means that results should be interpreted with caution. Excessive pronation of the foot while standing and female sex were found to be intrinsic risk factors in multiple prospective studies. Other intrinsic risk factors found in single prospective studies are higher body mass index, greater internal and external ranges of hip motion, and calf girth. Previous history of MTSS was shown to be an extrinsic risk factor.
The treatment of MTSS has been examined in three randomized controlled studies. In these studies rest is equal to any intervention. The use of neoprene or semi-rigid orthotics may help prevent MTSS, as evidenced by two large prospective studies. Hyperglycemia decreased medial amygdala projections to medial preoptic area in experimental model of Diabetes Mellitus. Full Text Available In Wistar rats, reproductive behavior is controlled in a neural circuit of ventral forebrain including the medial amygdala Me, bed nucleus of the stria terminalis BNST and medial preoptic area MPOA via perception of social odors.
Diabetes Mellitus DM is a widespread metabolic disease that affects many organs in a variety of levels. DM can cause central neuropathies such as neuronal apoptosis, dendritic atrophy, neurochemical alterations and also causes reproductive dysfunctions. So we hypothesized damage to the nuclei of this circuit can cause reproductive dysfunctions.
Therefore in this project we assessed diabetic effect on these nuclei. Also, coronal sections were analyzed with the TMB histochemistry method. Moreover, apoptotic cells were significantly observed in diabetic animals in contrast to control the group. In conclusion, these alterations of the circuit as a result of diabetes might be one of the reasons for reproductive dysfunctions. OBJECTIVE: The authors made a retrospective analysis of the results of 21 cases of cubital syndrome that were surgically treated with the partial medial epicondylectomy.
METHODS: From February to October , 21 patients with cubital tunnel syndrome were treated with the technique of elbow partial medial epicondylectomy associated to neurolysis of the ulnar nerve. Of these patients, 12 The right side was involved in 15 The medial collateral ligament of the elbow joint. Eighteen osteoligamentous elbow joint specimens were included in a study of the medial collateral ligament complex MCL.
The morphologic characteristics of the MCL were examined, and three-dimensional kinematic measurements were taken after selective ligament dissections were performed. On morph The morphologic characteristics of the MCL were examined, and three-dimensional kinematic measurements were taken after selective ligament dissections were performed This paper is an empirical study which goal is to know the relationship between individual characteristics of the auditor and the factors that shows their preliminary materiality judgement.
For this study, we have used quantitative method of research, using like variable auditor's personality type, in a hand, as is the MBTI and, in other hand, demographics, professionals and ethics variables. According to previous research, we find a determinate type of personality between Spanish auditors. However, our findings, don't permit to see any significant relationship between the auditor's personality type and the valuation of the another factors quantitative and qualitative which we are used to measure the preliminary materiality judgement. Differential roles for medial prefrontal and medial temporal cortices in schema-dependent encoding: From congruent to incongruent.
Information that is congruent with prior knowledge is generally remembered better than incongruent information. This effect of congruency on memory has been attributed to a facilitatory influence of activated schemas on memory encoding and consolidation processes, and hypothesised to reflect a shift between processing in medial temporal lobes MTL towards processing in medial prefrontal cortex mPFC.
To investigate this shift, we used functional magnetic resonance imaging fMRI to compare Sin embargo, en la literatura sobre el tema apenas se mencionan nombres femeninos, y cuando se hace es de una forma tangencial. It seems that the presence of women in the film direction is a young phenomenon which does not run beyond the second half of the 20th century.
Nevertheless, recent historiography is starting to confirm that the presence of women on the other side of the camera is a fact from the very beginning of the cinema, at the end of the 19th century. However, in the literature about this matter there are hardly female names and, when they exist, it is in a marginal way. The aim of the present article is to show some of the outstanding figures together with their principal productions, within their geographical, temporary and, even, social frame.
For this it has been used the scarce bibliography existing on. To investigate the reliability of the "ripple sign" on the upper surface of the medial femoral condyle in the diagnosis of medial longitudinal meniscal tears under arthroscope. Between June and June , 56 patients with knee injuries were included. There were 35 males and 21 females with an average age of The causes of injury were sports in 40 cases, falling in 10 cases, and traffic accident in 6 cases.
The injury was located at the left knee in 22 cases and at the right knee in 34 cases. The disease duration was days mean, Of 56 patients, 15 cases had simple medial meniscal injury; 41 cases had combined injuries, including anterior cruciate ligament injury in 38 cases, posterior cruciate ligament injury in 2 cases, and patellar dislocation in 1 case.
The "ripple sign" was observed under arthroscope before operation. Repair of medial meniscal injury and reconstruction of cruciate ligament were performed. The positive "ripple sign" was seen under arthroscope in all patients, who were diagnosed to have longitudinal meniscal tears, including 23 cases of mild "ripple sign" , 28 cases of moderate "ripple sign", and 5 cases of severe "ripple sign". The "ripple sign" on the upper surface of the medial femoral condyle is a reliable diagnostic evidence of medial longitudinal meniscal tears.

TCDD alters medial epithelial cell differentiation during palatogenesis. The incidence of clefting has been shown to be dose dependent after exposure on either gestation Day GD 10 or 12, although the embryo is more susceptible on GD TCDD-exposed palatal shelves meet but do not fuse, and programmed cell death of the medial epithelial cells is inhibited. The mechanism of action through which TCDD alters the program of medial cell development has not been examined in earlier studies, and it is not known whether the mechanism is the same regardless of the dose or developmental stage of exposure.
Embryonic palatal shelves were examined on GD 14, 15, or The degree of palatal closure, epithelial surface morphology, and cellular ultrastructure, the incorporation of [3H]TdR, the expression of EGF receptors, and the binding of I-EGF were assessed. The palatal shelves were of normal size and overall morphology, but fusion of the medial epithelia of the opposing shelves did not occur. TCDD prevented programmed cell death of the medial peridermal cells. The expression of EGF receptors by medial cells continued through Day 16 and the receptors were able to bind ligand.
The medial cells differentiated into a stratified, squamous, keratinizing epithelium. The shift in phenotype to an oral-like epithelium occurred after exposure on either GD 10 or Epidemiology of lateral and medial epicondylitis in a military population. To determine the epidemiology of lateral and medial epicondylitis in the U. Multivariate Poisson regression was used to calculate incidence rates IR and rate ratios RR among demographic groups.
The IRs for lateral and medial epicondylitis were 2. Female gender was a risk factor for lateral but not medial epicondylitis. Age greater than 40 and white race were significant risk factors for both conditions. We reported a case with acquired mirror movement in upper limbs due to the lesion of right medial frontal lobe including supplementary motor area, and also discussed a possible mechanism underlying it. A year-old right-handed woman developed left hemiparesis caused by cerebral hemorrhage in the right frontoparietal lobe, on April 5, She had right hemiparesis and right hemianopsia due to cerebral hemorrhage in the left parieto-occipital lobe, 13 days later.
As the patient was recovering from paresis, mirror movement appeared on upper limbs. The features of the mirror movement of this case are summarized as follows: 1 it appeared when using both proximal and distal region of upper limbs; 2 it appeared on left upper limb when the patient intended to move right upper limb or on right upper limb when intended to move left upper limb, while it appeared predominantly in the former; and 3 it was more remarkably found in habitual movement using gesture and pantomimic movement for the use of objects, and it was found in lower degree when actual object was used or when the patient tried to imitate the gesture of the examiner.
The lesions in MRI were found in medial region of right frontal lobe supplementary motor area, medial region of motor area, and cingulate gyrus , right medial parietal lobe, posterior region of right occipital lobe, and medial regions of left parietal and occipital lobes. There was no apparent abnormality in corpus callosum. Morphometry of medial gaps of human brain artery branches.
The bifurcation regions of the major human cerebral arteries are vulnerable to the formation of saccular aneurysms. A consistent feature of these bifurcations is a discontinuity of the tunica media at the apex of the flow divider. The objective was to measure the 3-dimensional geometry of these medial gaps or " medial defects.
The apex and adjacent regions were examined and measurements were made from high-magnification photomicrographs, or projection microscope images, of the gap dimensions at multiple levels through the bifurcation. Plots were made of the width of the media as a function of distance from the apex. The media at each edge of the medial gap widened over a short distance, reaching the full width of the media of the contiguous daughter vessel. Medial gap dimensions were compared with the planar angle of the bifurcation, and a strong negative correlation was found, ie, the acute angled branches have the more prominent medial gaps.
A discontinuity of the media at the apex was seen in all the bifurcations examined and was also found in the junction regions of brain arteries. We determined that the gap width is continuous with well-defined dimensions throughout its length and average length-to-width ratio of 6. The gaps were generally centered on the prominence of the apical ridge. Abductor spasmodic dysphonia, a difficult-to-treat laryngologic condition, is characterized by spasms causing the vocal folds to remain abducted despite efforts to adduct them during phonation.
Traditional treatment for abductor spasmodic dysphonia-botulinum toxin injection into the posterior cricoarytenoid muscle-can be both technically challenging and uncomfortable. Due to the difficulty of needle placement, it is often unsuccessful. The purpose of this investigation is to present a previously undescribed treatment for abductor spasmodic dysphonia-bilateral vocal fold medialization. A retrospective case review of all cases of abductor spasmodic dysphonia treated in a tertiary care laryngology practice with bilateral vocal fold medialization over a year period was performed.

The Voice Handicap Index and the Voice-Related Quality of Life surveys were utilized to assess patient satisfaction with voice outcome. Six patients with abductor spasmodic dysphonia treated with bilateral vocal fold medialization were identified. Disease severity ranged from mild to severe. All six patients reported statistically significant improvement in nearly all Voice Handicap Index and Voice-Related Quality of Life parameters. They reported fewer voice breaks and greater ease of communication.
Results were noted immediately and symptoms continue to be well controlled for many years following medialization. Bilateral vocal fold medialization is a safe and effective treatment for abductor spasmodic dysphonia. It is performed under local anesthesia and provides phonation improvement in the short and long term. Ultrastructure of medial rectus muscles in patients with intermittent exotropia. The normal control group included five patients without strabismus and undergoing eye enucleation.
Hematoxylin and eosin staining and transmission electron microscopy were used to visualize the medial recti. Western blot was used to determine the levels of myosin and actin. RESULTS Varying fiber thickness, atrophy, and misalignment of the medial recti were visualized under optical microscope in patients with exotropia.
Electron microscopy revealed sarcomere destruction, myofilament disintegration, unclear dark and light bands, collagen proliferation, and fibrosis. The adolescent group manifested significantly higher levels of myosin and actin than the adult group Pstronger contraction of the medial recti compared with older patients. Our findings suggest that childhood was the appropriate time for surgery as the benefit of the intervention was better than in adulthood.
An in vitro analysis of medial structures and a medial soft tissue reconstruction in a constrained condylar total knee arthroplasty. The aim of this study was to quantify the medial soft tissue contributions to stability following constrained condylar CC total knee arthroplasty TKA and determine whether a medial reconstruction could restore stability to a soft tissue-deficient, CC-TKA knee.
The deep and superficial medial collateral ligaments dMCL, sMCL and posteromedial capsule PMC were transected and their relative contributions to stabilising the applied loads were quantified. After complete medial soft tissue transection, a reconstruction using a semitendinosus tendon graft was performed, and the effect on kinematic behaviour under equivocal conditions was measured.
No significant differences were found between the rotational laxities of the reconstructed knee to the pre-deficient state for the arc of motion examined. There is contention whether a CC-TKA can function with medial deficiency or more constraint is required. However, in such cases, combining the CC-TKA with a medial soft tissue reconstruction may be considered as an alternative to a hinged implant. Typing of MRI in medial meniscus degeneration in relation to radiological grade in medial compartmental osteoarthritis of the knee.
School of Medicine. The advancement of degeneration of 50 medial menisci in patients with medial compartmental osteoarthritic knees OA were evaluated with magnetic resonance imaging MRI. The average age of the patients was According to a radiographical grading system, 6 knees were classified as Grade 1, 24 as Grade 2, 16 as Grade 3, and 4 as Grade 4.
The extent and the location of a high intensity region in MRI were observed in 3 parts of the meniscus, namely, the anterior, middle and posterior part. In Grade 1, no high intensity region was observed in 3 knees, and a high intensity region was observed only in the posterior part in 2 knees.
A high intensity region was observed from the medial to the posterior part in 13 knees, and only in the posterior part in 10 knees of Grade 2; from the medial to the posterior part in 12 knees, and only in the posterior part in 3 knees of Grade 3, and from the anterior to the posterior part in 2 knees of Grade 4. The shape of the high intensity region in the medial meniscus was classified into 5 types, as follows: Type 1, there was no high intensity region; Type 2, the high intensity region was observed to be restricted within the meniscus; Type 3, the high intensity region resembled a horizontal tear; Type 4, the high intensity region was observed as all of the medial joint space without a marginal area; Type 5, the high intensity region was observed as all of the medial joint space.
In Grade 1, 3 knees were classified as Type 1, and 2 knees as Type 2; in Grade 2, 7 knees as Type 2, and 13 knees as Type 3, and 4 knees into Type 4; in Grade 3, 6 knees as Type 3, and 7 knees as Type 4; and in Grade 4, 2 knees as Type 4, and 2 knees as Type 5. These findings might suggest that the degeneration of medial meniscus in the medial type of OA was accelerated by mechanical stress due to varus deformity. The resulting, non-discrete approximation is shown to converge to the medial axis as the sampling density approaches infinity.
While there is no subquadratic upper bound on the output complexity of previous algorithms for non-discrete medial axis approximation, the output of our algorithm is guaranteed to be of linear size.
Full Text Available Purpose: To evaluate the efficiency of medial rectus advancement surgery in consecutive exotropia. Material and Methods: The study group consisted of 20 cases, 10 male, 10 female, who were diagnosed as consecutive exotropia and underwent surgery between at Cukurova University Medical Faculty Ophthalmology Department.
Records of the patients were investigated retrospectively. We evaluated best corrected visual acuity, existence of ambliopia, postoperative duration following the first surgery and applied surgical procedures. Postoperative deviation lower than 10 PD were assesed as successful. Results: We only applied bilateral medial rectus advancement surgery to 6 and unilateral medial rectus advancement surgery to 5 patients and obtained intended surgical result in these 11 cases. Discussion: Consecutive exotropia can appear years after surgery and is an important late period complication.
Accurrate prediction of the propotion of advancement surgery and adjustment is not always possible because of intensive fybrosis in operated muscles and enviroment tissue. Magnetic resonance imaging findings in patients with medial epicondylitis. Kijowski, Richard; Smet, Arthur A. To compare the MR imaging findings of 13 patients with clinically diagnosed medial epicondylitis with the MR imaging findings of 26 patients of similar age with no clinical evidence of medial epicondylitis.
The study group consisted of 13 patients with clinically diagnosed medial epicondylitis. The control group consisted of 26 patients of similar age with no clinical evidence of medial epicondylitis. The medical records and MR imaging findings of these patients were retrospectively reviewed by two fellowship-trained musculoskeletal radiologists. Eleven of the 13 patients in the study group had thickening and increased signal intensity of the common flexor tendon on both T1-weighted and T2-weighted images.
The remaining two patients in the study group had soft tissue edema around a normal-appearing common flexor tendon. Twenty-one of the 26 patients in the control group had a normal-appearing common flexor tendon on MR imaging. Three patients in the control group had a thickened common flexor tendon which was of intermediate signal intensity on T1-weighted images but of uniform low signal intensity on T2-weighted images. Two patients in the control group had a thickened common flexor tendon which was of intermediate signal intensity on both T1-weighted and T2-weighted images.
None of the patients in the control group had soft tissue edema around the common flexor tendon. MR imaging findings of patients with clinically diagnosed medial epicondylitis included thickening and increased T1 and T2 signal intensity of the common flexor tendon and soft tissue edema around the common flexor tendon.
The presence of intermediate to high T2 signal intensity or high T2 signal intensity within the common flexor tendon and the presence of paratendinous soft tissue edema were the most specific findings of medial epicondylitis on MR imaging.

Full Text Available A new axial pattern flap based on the terminal branches of the medial circumflex femoral artery is described for coverage of ischial pressure sore.
Based on the terminal branches of the transverse branch of medial circumflex femoral artery, which exit through the gap between the quadratus femoris muscle above and the upper border of adductor magnus muscle below, this fascio cutaneous flap is much smaller than the posterior thigh flap but extremely useful to cover ischeal pressure sores. The skin redundancy below the gluteal fold allows a primary closure of the donor defect. It can also be used in combination with biceps femoris muscle flap.
Communication between radial nerve and medial cutaneous nerve of forearm. Full Text Available Radial nerve is usually a branch of the posterior cord of the brachial plexus. It innervates triceps, anconeous, brachialis, brachioradialis, extensor carpi radialis longus muscles and gives the posterior cutaneous nerve of the arm, lower lateral cutaneous nerve of arm, posterior cutaneous nerve of forearm; without exhibiting any communication with the medial cutaneous nerve of forearm or any other nerve.
We report communication between the radial nerve and medial cutaneous nerve of forearm on the left side in a year-old male cadaver. The right sided structures were found to be normal.

Unicompartmental Knee Arthroplasty UKA is a common procedure for the management of isolated osteoarthritis. UKA is considered less invasive compared to total knee arthroplasty, associated with less operative time, blood loss and faster recovery.
Isolated lateral osteoarthritis is a relatively uncommon clinical problem, with an incidence about ten times lower than the medial compartment. In addition, it's historically considered more challenging and with poorer results. The aim of this paper was to compare current indications, modes of failure, survivorship and clinical results of medial and lateral UKA by a narrative review of the latest literature. Medial patellofemoral ligament: Research progress in anatomy and injury imaging. The medial patellofemoral ligament MPFL is considered as the most important soft tissue restraint providing medial stability of the patellofemoral joint.
During patellar dislocation, the MPFL is subjected to severe stretching forces, resulting in injuries of the ligament in the most patients. With the development of medical imaging technology, a variety of non-invasive diagnostic imaging methods have been becoming important means in diagnosis of MPFL injury. Del gobierno a la gobernanza. Full Text Available In this paper we analyze the introduction of multi-actor, multi-level and multi-type governance systems in Spain, on the basis of several recent field studies.
On the one hand, regulatory decision making is undergoing a profound transformation in response to citizen demands. On the other hand, the controversies related to the social and environmental effects of emerging technologies are creating new social dynamics of technology development and application. A diversity of social actors is forming new alliances which are exerting decisive influence on the trajectories of such emerging technologies.

Maxillary sinus inverted papilloma entails medial maxillectomy and is associated with high incidence of recurrence.
To study the impact of prior surgery on recurrence rate after transnasal endoscopic medial maxillectomy. Eighteen patients with primary and 33 with recurrent maxillary sinus inverted papilloma underwent transnasal endoscopic medial maxillectomy. Caldwell-Luc operation was the primary surgery in 12 patients, transnasal endoscopic resection in 20, and midfacial degloving technique in one. The follow-up period ranged between 2 to Recurrence is more common in recurrent maxillary sinus inverted papilloma than primary lesions.
Recurrent maxillary sinus inverted papilloma after Caldwell-Luc operation has higher incidence of recurrence than after transnasal endoscopic resection. Default network connectivity in medial temporal lobe amnesia. There is substantial overlap between the brain regions supporting episodic memory and the default network.
However, in humans, the impact of bilateral medial temporal lobe MTL damage on a large-scale neural network such as the default mode network is unknown. To examine this issue, resting fMRI was performed with amnesic patients and control participants. Seed-based functional connectivity analyses revealed robust default network connectivity in amnesia in cortical default network regions such as medial prefrontal cortex, posterior medial cortex, and lateral parietal cortex, as well as evidence of connectivity to residual MTL tissue.
Relative to control participants, decreased posterior cingulate cortex connectivity to MTL and increased connectivity to cortical default network regions including lateral parietal and medial prefrontal cortex were observed in amnesic patients. In contrast, somatomotor network connectivity was intact in amnesic patients, indicating that bilateral MTL lesions may selectively impact the default network. Changes in default network connectivity in amnesia were largely restricted to the MTL subsystem, providing preliminary support from MTL amnesic patients that the default network can be fractionated into functionally and structurally distinct components.
To our knowledge, this is the first examination of the default network in amnesia. Medial peritalar fracture dislocation of the talar body. Full Text Available Peritalar fracture dislocations typically involve the talar neck and are classified according to Hawkins. To our knowledge, peritalar fracture dislocation involving the talar body has not been formally reported.
In this article, we describe a case of peritalar fracture dislocation of the talar body. Keywords: Peritalar dislocation, Talus fracture, Talar body fracture dislocation, Medial subtalar dislocation. MR imaging findings of medial tibial crest friction. Objective: Medial tibial condyle bone marrow edema BME , associated with soft tissue edema STe surrounding the medial collateral ligament, was incidentally observed in MRI examinations of young and athletic individuals.
The aim of the present study was to 1. Prospectively investigate the association between these findings and coexistence of localized pain, and 2. Explore the possible contribution of the tibial morphology to its pathogenesis. Methods: The medial tibial condyle crest was evaluated in knee MRI examinations. The angle and depth were measured by two separate evaluators. A third evaluator blindly assessed the presence of pain at this site. Results: BME associated with STe was found in 24 patients with no history of previous trauma, osteoarthritis, tumor or pes anserine bursitis.
The mean crest angle was MRI is a highly specific and sensitive imaging modality for its diagnosis. Comparison of Medial and Posterior Surgical Approaches in Oct 26, The grading system defined by Flynn et al. Medial tibial stress syndrome MTSS , also known as shin splints, is one of the most common sports injuries. There is a lack of knowledge regarding making the. Aetiology, imaging and treatment of medial tibial stress syndrome. The work contained is this thesis discusses aetiology, imaging and treatment of a common leg injury: medial tibial stress syndrome MTSS.
Although a common injury, the number of scientific articles on this topic is relatively low as is explained in chapter 1. This chapter also highlights that the. Anatomical segmentation of the human medial prefrontal cortex. Corcoles-Parada, M. The medial prefrontal areas 32, 24, 14, and 25 mPFC form part of the limbic memory system, but little is known about their functional specialization in humans.
To add anatomical precision to structural and functional magnetic resonance imaging MRI data, we aimed to identify these mPFC subareas. The function and survival time of unicompartmental knee prostheses for patients with severe gonarthrosis have been improved the past few years by developments in their design, the instrumentarium and the surgical technique. A medial unicompartmental knee prosthesis may be indicated in patients with. Ecological divergence and medial cuneiform morphology in gorillas. Gorillas are more closely related to each other than to any other extant primate and are all terrestrial knuckle-walkers, but taxa differ along a gradient of dietary strategies and the frequency of arboreality in their behavioral repertoire.
In this study, we test the hypothesis that medial cuneiform morphology falls on a morphocline in gorillas that tracks function related to hallucial abduction ability and relative frequency of arboreality. This morphocline predicts that western gorillas, being the most arboreal, should display a medial cuneiform anatomy that reflects the greatest hallucial abduction ability, followed by grauer gorillas, and then by mountain gorillas. Using a three-dimensional methodology to measure angles between articular surfaces, relative articular and nonarticular areas, and the curvatures of the hallucial articular surface, the functional predictions are partially confirmed in separating western gorillas from both eastern gorillas.
Western gorillas are characterized by a more medially oriented, proportionately larger, and more mediolaterally curved hallucial facet than are eastern gorillas. These characteristics follow the predictions for a more prehensile hallux in western gorillas relative to a more stable, plantigrade hallux in eastern gorillas. The characteristics that distinguish eastern gorilla taxa from one another appear unrelated to hallucial abduction ability or frequency of arboreality. In total, this reexamination of medial cuneiform morphology suggests differentiation between eastern and western gorillas due to a longstanding ecological divergence and more recent and possibly non-adaptive differences between eastern taxa.
