Myoepitheliomas are well-established to occur in the salivary glands, but they have also been described in the breast, upper aerodigestive tract, skin, and soft tissues. We report here on a unique case of primary myoepithelioma that occurred in the right testis of a 28-year-old man. The tumor was entirely confined to the testis and it was clearly separated from the epididymis. Histopathology revealed mixed architectural patterns in which the reticular areas merged into the chondromyxoid stroma. The tumor cells, which were focally immunoreactive to pancytokeratin and S-100 protein, were round to ovoid and spindly arranged in cords, strands, and fascicles. They showed mild nuclear pleomorphism, sparse mitotic figures and a low Ki-67 proliferative index. There was no ductal differentiation in the tumor. To the best of our knowledge, there has been only one case report of a primary testicular myoepithelioma in the English medical literature.

There are more than 120 different theories on the possible cause of sudden infant death syndrome (SIDS). Recent studies indicate a possible role of infections in SIDS, one of which suggested that a maximum percentage of up to 43.5% of SIDS showed virus-induced myocardial affection. The enterovirus, mainly the cardiotropic coxsackievirus group B, serotypes B1-B5, which causes most of viral myocarditis in infancy, seems to be the most common virus associated with SIDS. The aim of our study was to investigate the enterovirus-induced myocardial affections in cases of SIDS. All 7 cases of postmortem heart samples from SIDS victims were studied. Postmortem heart samples of non-SIDS death in perinatal period, infancy and young childhood, pediatric cases of myocarditis and unnatural death in young adult were served as controls. An immunohistochemical study was performed on all samples using monoclonal mouse anti-enterovirus antibody and anti-LCA with quantification of positive cells. Our results demonstrated that 2 of 7 cases of SIDS showed strong immunoreactivity in the myocardium against antienterovirus antibody and there was more inflammatory cell infiltrate in SIDS cases than controls. Our study suggests that the enteroviral myocardial affection would be a possible role in pathogenesis of SIDS.

Menisco-meniscal ligaments in knee joint are known as four variants, anterior and posterior transverse meniscal ligament, medial and lateral oblique menisco-meniscal ligament. The ligament which originates from the anterior horn of the meniscus and attached to the posterior horn of the same meniscus, so-called unilateral menisco-meniscal ligament is extremely rare in English literature. The authors experienced a case of medial unilateral menisco-meniscal ligament with posterior horn tear of the medial meniscus in a 49-year-old man. We report this case with a review of literature.

Since patients with intracranial neoplasms usually represent their neurological symptoms rather early in the course of the disease, sudden unexpected death due to intracranial neoplasms is an uncommon event seen only exceptionally in medicolegal autopsy practice. Although meningiom is one of the most common primary intracranial neoplasms, sudden death due to the tumor is an uncommon event. We report a sudden, unexpected death of a 56-year-old female with an undiagnosed olfactory groove meningioma. It is assumed that peritumoral edema is related to the sudden death among the several mechanisms.

PURPOSE: The purpose of this study was to evaluate the frequency of troughing and stress fracture, which are the major complications of scarf osteotomy, and to suggest methods to prevent these complications. MATERIALS AND METHODS: We reviewed 243 cases of 137 patients treated with the scarf osteotomy for hallux valgus from January 2005 to December 2012. The mean follow-up period was 2.8 years. During the scarf osteotomy, a long oblique longitudinal osteotomy was performed in order to decrease the possibility of troughing and stress fracture. Radiographs of lateral view of the foot were obtained and the thicknesses of the first metatarsal base at the sagittal plane were measured and compared. RESULTS: There was no troughing during fragment translation and screw fixation intraoperatively. Radiographs of lateral view of the foot taken preoperatively and at the last follow-up showed that the mean thickness of the first metatarsal was 22.4 mm preoperatively and 21.6 mm at the last follow-up, with a mean difference of 0.8 mm. And no stress fracture was observed. CONCLUSION: To prevent troughing and stress fracture, a long oblique longitudinal cut, parallel to the first metatarsal plantar surface, was performed, making both ends of the proximal segment truncated cone-shape, and securing the strong bony strut of the proximal segment. No troughing or stress fracture was experienced with scarf osteotomy.

PURPOSE: The purpose of this study is to evaluate the effect of axial shortening metatarsal osteotomy on the treatment of advanced rheumatoid arthritis patients with severe hallux valgus and claw toe deformity of lesser toes which is used for preserving the metatarsophalangeal joint. MATERIALS AND METHODS: From January 2005 to June 2009, 18 cases of axial shortening metatarsal osteotomy in advanced rheumatoid arthritis were reviewed ; all of them followed up for more than 2 years after surgical procedures and the mean follow up period was 3.4 years. We performed axial shortening Scarf osteotomy and Akin osteotomy for hallux valgus and Weil osteotomy with soft tissue release for claw toe of lesser toes, respectively. We measured preoperative and postoperative hallux valgus angle, each metatarsal shortening length and the range of motion of the metatarsophalangeal joints through radiographic and clinical examination and compared them each other. Clinical results were evaluated by American Orthopedic Foot and Ankle Society (AOFAS) score and subjective satisfaction of the patients. RESULTS: The hallux valgus angle was reduced from the preoperative mean value of 44.8 degree to 9.0 degree postoperatively and the range of motion of the metatarsophalangeal joint of great toe and lesser toes was increased from the mean of 21.7 degree and 11.0 degree preoperatively to 38.0 degree and 32.5 degree, respectively at postoperation. Also, the mean AOFAS score was improved from 26.5 points to 67.4 points. CONCLUSION: Axial shortening osteotomy is a useful method to correct the deformity and preserve the metatarsophalangeal joint for severe hallux valgus and claw toe deformity in advanced rheumatoid arthritis.

PURPOSE: Recurrence is one of the most common complications after primary correction for hallux valgus deformities. The purpose of this study was to evaluate the usefulness of Scarf osteotomy with axial decompression in the treatment of recurrent hallux valgus. MATERIALS AND METHODS: From April 2006 to April 2011, 14 cases (12 patients) of recurrent hallux valgus were managed with shortening Scarf osteotomy. Preoperative and postoperative radiographs were reviewed for the measurement of the hallux valgus angle (HVA), intermetatarsal angle (IMA), and the amount of the 1st metatarsal shortening. Clinical outcomes including the visual analogue scale (VAS), the AOFAS score, and the range of motion [ROM] of the 1st metatarsophalangeal (MTP) joint were evaluated. RESULTS: The mean HVA decreased from 27.9 degrees to 5.2 and the mean IMA decreased from 12.9 to 3.4. The mean VAS improved from 5.3 to 0.3 and the mean AOFAS score improved from 41 to 90. The mean amount of the 1st metatarsal shortening was 3.4 mm (2-5). The mean ROM of the 1st MTP joint improved from 22 degrees (15-35) to 68 (55-75). CONCLUSION: Scarf osteotomy associated with axial decompression can be a useful revision procedure for the treatment of recurrent hallux valgus deformity.

Stress fracture usually occurs in physically active individuals as a result of repetitive strenuous muscle and tendon forces acting on bones that have not adapted to such forces. To the best of our knowledge, the literature contains few reports of stress fracture of the patella. We report herein on a case of a nine-year-old female who developed a stress fracture in the patella after running.

OBJECTIVE: This study was conducted to identify demographic variables and illness related variables which may affect the severity of self-engulfment in the patients with schizophrenia. We also studied the relationship between self-engulfment and insight, and the relationship between self-engulfment and self-esteem. METHODS: Data on demographic variables and illness related variables for the subjects were gathered from hospital records and clinical interviews by the psychiatrists. Degree of insight far the subjects was assessed through clinical interviews by the psychiatrists. Degree of self-engulfment and self-esteem for the subject was assessed from the self-engulfment scale and the self-esteem state respectively. A total of 111 patients with schizophrenia were selected for statistical analysis. RESULTS: 1) The females exhibited significantly higher socres than the males on the self-engulfment scale . 2) There was no illness related variable, which exhibited a significant difference among subgroups on the self-engulfment scale. 3) There was no significant correlation between the self-engulfment stores and the insight scores . 4) There was a significantly inverse correlation between the self-engulfment scores and the self esteem scores. CONCLUSION: The results of this preliminary study suggest that self-engulfment may develop despite lack of insight, and that there was inverse relationship between self-engulfment and self-esteem in the patients with schizophrenia. It also suggests that females are more subject to self-engulfment than males. So, authors suggest that it is valuable to do further studies of self-engulfment in the patients with schizophrenia.

We investigated characteristics associated with the efficacy of dipeptidyl peptidase-4 inhibitors (DPP4i) in Korean patients with type 2 diabetes. We reviewed medical records of 477 patients who had taken sitagliptin or vildagliptin longer than 40 weeks. Response to DPP4i was evaluated with HbA1c change after therapy (DeltaHbA1c). The Student's t-test between good responders (GR: DeltaHbA1c > 1.0%) and poor responders (PR: DeltaHbA1c < 0.5%), a correlation analysis among clinical parameters, and a linear multivariate regression analysis were performed. The mean age was 60 yr, duration of diabetes 11 yr and HbA1c was 8.1%. Baseline fasting plasma glucose (FPG), HbA1c, C-peptide, and creatinine were significantly higher in the GR compared to the PR. Duration of diabetes, FPG, HbA1c, C-peptide and creatinine were significantly correlated with DeltaHbA1c. In the multivariate analysis, age (r2 = 0.006), duration of diabetes (r2 = 0.019), HbA1c (r2 = 0.296), and creatinine levels (r2 = 0.024) were independent predictors for the response to DPP4i. Body mass index and insulin resistance were not associated with the response to DPP4i. In conclusion, better response to DPP4i would be expected in Korean patients with type 2 diabetes who have higher baseline HbA1c and creatinine levels with shorter duration of diabetes.
