The fibrosis involved in gluteus maximus causing limitation of flexion and adduction of the hip has become a recognized clinical entity since the first report by Fernandez de Valderrma in 1969. Its most constant and characteristic histologic feature was substitution of the fibrous tissue in the definitive etiology was unknown but presumed to be multiple intramuscular injections. Authors present three cases of the fibrosis involving gluteus maximus. In two cases Z-lengthening was performed on the thickened fibrous bands with good results.

Various kinds of bone cements mixed with antibiotics have been widely used for treatment and prevention of infections, especially combined with bone defects. But bone cements have some disadvantages in that they are rather expensive and capable of incurring some complications such ss fibrosis of surrounding soft tissue or local erosion of bone, and furthermore, they must be removed after infection is controlled for bone graft to fill up the defects because they do not have properties of osteoconduction or osteoinduction. So we have come to the idea of using theoretically advantageous plaster of paris to take place of bone cements, and performed in-vitro experiment upon the effectiveness of plaster of paris pellets containing antibiotics, then obtained good results comparable to those from many experimental studies using bone cements. By this, we think that it would be possible in the future to treat and prevent infections supervening bone defects with plaster of paris mixed up with antibiotics. The results are as follows : 1. Sustained release of large amount of antibiotics from plaster of paris enough to exert inhibitory activity on abcterial growth, and there was a direct relationship between concentrations of eluted antibiotics and diameters of inhibitory zones. 2. Tobramycin was capable of inhibiting the growth of S. aureus, E. coli, and Ps. aeruginosa for 7 days at maximum. 3. Cephradine inhibited the growth of S. aureus and E. coli but did not affect that of Ps. aeruginosa. 4. The maximum antibacterial activity wss reached within first 24 hours from the start of elution of antibiotics from plaster of paris.

Malignant growth of the small bowel accounts for approximately 1 to 3 percent of malignant tumors of the gastrointestinal tract. Leiomyosarcomas are the second most common primary tumor of the small bowel, their frequency being one-third to one-half of adenocarcinoma. The common clinical symptoms of leiomyosarcoma of the small intestine are hemorrhage and abdominal pain. Accurate diagnosis cannot be based on solely on the roentgenographic finding, although in certain situations the dignosis of leiomyosarcoma may be suggested strongly. We report a case of bleeding leiomyosarcoma located in the second portion of the duodenum which was first recognized by endoscopic examination and confirmed by explolaparotomy.

BACKGROUND AND OBJECTIVES: Several prognostic factors are known to be related to the recovery of sudden sensorineural hearing loss (SSNHL). Recent studies have suggested that cardiovascular risk factors (CVRFs) are associated with the occurrence of SSNHL. However, the value of CVRFs as a predictor of recovery in patients with SSNHL has been rarely evaluated. We aim to evaluate the prognostic value of CVRFs in relation to hearing recovery of SSNHL. SUBJECTS AND METHOD: A total of 278 patients who were diagnosed and treated for SSNHL and who underwent blood sampling and follow-ups for more than 3 months were reviewed retrospectively. We reviewed CVRFs such as age, body mass index, blood pressure, cholesterol, smoking history, the presence of diabetes mellitus and other related underlying diseases. Patients were divided into three groups (low, medium, and high CVRF groups) according to the CVRF grades. Hearing thresholds were repeatedly measured on the initial visit, 1 week, 1 month and 3 months after treatment. Treatment outcome was analyzed by comparing hearing recovery rate and post-treatment audiometric changes among the three CVRF groups. RESULTS: Seventy (25.2%), 129 (46.4%) and 79 (28.4%) patients were included into the low, medium and high CVRF groups, respectively. The hearing threshold was significantly reduced at 3 months after treatment in all three groups (p<0.001). The hearing recovery rate of the low CVRF group was significantly higher than that of the medium and high CVRF group (p=0.011). On the last visit, the high CVRF group significantly showed more poor hearing improvement than the low CVRF group did (p=0.045). CONCLUSION: Our findings suggest that the presence of CVRFs may be a poor prognostic sign for hearing recovery in patients with SSNHL.

BACKGROUND: Cryptotia correction by V-Y advancement of a temporal triangular flap was introduced in 2005. However, despite the several advantages of V-Y advancement, visible scars at the donor site are problematic. As a result, a Z-plasty technique was considered for skin deficiency in mild cases. Therefore, we introduce a new surgical scheme for cryptotia correction based on considerations of techniques and complications that arose in our clinic. METHODS: Between 2000 and 2013, 26 patients (35 cases) of cryptotia were treated. Seventeen patients had unilateral cryptotia and nine had bilateral cryptotia. Two corrective methods were used, Z-plasty or V-Y advancement, based on the severity. In mild cases, Z-plasty was used for correction and in severe cases, V-Y flap advancement was used for more skin supplement. RESULTS: Follow-up periods ranged from 6 months to 1.5 years. The results obtained were relatively favorable. Nine cases of mild deformity were corrected by Z-plasty, and the other 26 cases with mild or severe deformities were corrected by V-Y advancement. In Z-plasty cases, there was one hypertrophic scar and in V-Y advancement cases, seven resulted in visible scarring and three in skin sloughing. CONCLUSION: The main advantage of Z-plasty is a lower likelihood of visible scarring at the donor site. In mild cases, Z-plasty may be a good alternative, but in severe cases, V-Y advancement is probably the best option for more skin supplement.

Tracheoesophageal fistula is a rare disease of abnormal communication between esopha- gus and respiratory system. The common causes are the acquired origins in adult such as trauma, infection of the adjacent organs, malignant tumor, and foreign body. Among the traumatic origins, chemical drug, the procedure of the dilatation on the stenotic area, blunt trauma(fall, collisions), penetrating trauma(bullet, knife), and pressure injury are much more common than others. Recently, trauma and foreign body in the esophagus and bronchus are becoming the main cause of the tracheoesophageal fistula, however the frequency of the development of tracheoesophageal fistula caused by the infectious diseases is getting decreased. Fibrinogen-thrombin glue stimulates the healing process of the wound and the ulcer. We treated a 52-year-old male patient with nan-inalignant tracheoesophageal fistula, who had symtoms of pharyngolaryngeal and chest discomfort concomitant with a paroxysmal cough on swallowing food which were caused by fish bone. The diagnosis of tracheoesophageal fistula was made by the esophagogram, chest CT, and esop aecopy. By using the therapeutic endoscopy with an injection of the fibrinogen-glue, the tracheoesopeal fistula was obliterated completely with dramatic symptomatic improvement. Here we conqluded that this method would be the one of the best methods for the treatment of tracheoesophageal fistula.

Myeloid-related protein (MRP)8/MRP14 is an endogenous Toll-like receptor 4 (TLR4) ligand and is abundant in synovial fluid (SF) of rheumatoid arthritis (RA) patients. Belonging to damage-associated molecular patterns, it amplifies proinflammatory mediators and facilitates a wide range of inflammatory and autoimmune diseases. Interleukin (IL)-17-producing T-helper (Th)17 cells have a crucial role in RA pathogenesis, and IL-6 is the key factor promoting Th17 differentiation. We investigated whether the level of MRP8/MRP14 is positively associated with IL-6 and IL-17 levels in RA SF and found that MRP8/MRP14 level had a significant correlation with IL-6 and IL-17 levels in RA SF. We also observed that MRP8-induced IL-17 production by peripheral blood mononuclear cells but MRP14 did not. Upon stimulation with MRP8, IL-6 production was enhanced by RA fibroblast-like synoviocytes (FLS) and was further elevated by coculturing RA FLS with activated CD4+ T cells. Moreover, we demonstrated that MRP8-activated IL-6 production by RA FLS promoted differentiation of Th17 cells using the coculture system consisting of CD4+ T cells and RA FLS. In addition, IL-6 blockade attenuated Th17 polarization of CD4+ T cells in the cocultures. Inhibitor studies revealed that MRP8 increased IL-6 production in RA FLS via TLR4/phosphoinositide 3-kinase/nuclear factor-kappaB and mitogen-activated protein kinase signaling pathways. Our results show that MRP8 has a crucial role in stimulating IL-6 expression by RA FLS, and subsequently promotes Th17 differentiation in RA, suggesting that neutralizing MRP8 level in RA synovium may be an effective therapeutic strategy in RA treatment.

OBJECTIVE: The purpose of this study was to determine the normal morphometric landmarks of the uniting and dividing points of the brachial plexus (BP) in the periclavicular region to provide useful guidance in surgery of BP injuries. METHODS: A total of 20 brachial plexuses were obtained from 10 adult, formalin-fixed cadavers. Distances were measured on the basis of the Chassaignac tubercle (CT), and the most lateral margin of the BP (LMBP) crossing the superior and inferior edge of the clavicle. RESULTS: LMBP was located within 25 mm medially from the midpoint in all subjects. In the supraclavicular region, the upper trunk uniting at 21 +/- 7 mm from the CT, separating into divisions at 42 +/- 5 mm from the CT, and dividing at 19 +/- 4 mm from the LMBP crossing the superior edge of the clavicle. In the infraclavicular region, the distance from the inferior edge of the clavicle to the musculocutaneous nerve (MCN) origin was 49 +/- 1 mm, to the median nerve origin 57 +/- 7 mm, and the ulnar nerve origin 48 +/- 6 mm. From the lateral margin of the pectoralis minor to the MCN origin the distance averaged 3.3 +/- 10 mm. Mean diameter of the MCN was 4.3 +/- 1.1 mm (range, 2.5-6.0) in males (n = 6), and 3.1 +/- 1.5 mm (range, 1.6-4.0) in females (n = 4). CONCLUSION: We hope these data will aid in understanding the anatomy of the BP and in planning surgical treatment in BP injuries.
