Sternoclavicular joint posterior dislocations are considered a very uncommon, and type of injury where if esophagus or airway injury occurs behind the clavicle, it poses a high risk to the patient. In addition, if epiphyseal fracture occurs as a result of the sternoclavicular joint posterior dislocation, surgical treatment is often required. However, in the absence of a complete ossification of the clavicle, it is difficult to differentiate between a simple dislocation and epiphyseal fracture-dislocation solely based on simple radiographs or computed tomography scans. In this case report, the authors present a case in which a sternoclavicular joint posterior dislocation was diagnosed in a 14-year-old male athlete. The case report discusses how the posterior dislocation without epiphyseal fracture was diagnosed using an ultrasound and subsequently treated with successful outcomes using manual reduction. The case report presents our findings along with discussion that includes a literature review of relevant research.

Sjogren's syndrome has been considered to be an autoimmune disease affecting various organs including salivary and lacrimal glands. It occurs most commonly in middle-aged women, and less than 20 cases with primary Sjogren's syndrome have been reported in children. An 11-yim-old boy presented with recurrent annular erythema on the face that had been present for 2 years. A schirmers test showed a positive result. ANA was detected at a dilution of 1:640. Anti-Ro/SSA and anti-La/SSB antibodies were also detected. On histological examination, lymphocytes were infiltrated in the periappendegeal areas as well as the papillary and reticular dernis. The skin findimg is uncommon in children, but has become a characteristic feature of childhood Sjogrens syndrome with anti-Ro and/or anti-La antibodies.

PURPOSE: Sexual differences in the incidence and crystalline composition of urinary stones in humans are well-known, but it is unclear why men have a higher incidence of calcium oxalate stones than women. We investigated the effects of male sex hormones on stone formation using an ethylene glycol (EG) - induced urolithiasis model in rats. MATERIALS AND METHODS: Adult male Sprague-Dawley rats were divided into 4 groups, each containing 10 rats. One group of rats was left untreated and served as control. The other 3 groups were fed a 1% ethylene glycol (EG) lithogenic diet for 4 weeks. Among these, one group was non-castrated, one group was castrated and one group was non-castrated and given finasteride orally. Serum testosterone, creatinine, electrolytes, 24-hour urine levels of oxalate and citrate, and creatinine clearance were measured. The crystal deposits were examined by light and polarizing microscopes. RESULTS: Testosterone promoted calcium oxalate stone formation in EG - treated rats. Finasteride administration significantly decreased urinary oxalate excretion and calcium oxalate deposition, compared with controls. Urinary citrate was significantly decreased in EG-treated rats, but was not influenced by castration or administration of finasteride. There were no significant differences in serum concentrations of creatinine, sodium, or potassium among the control and experimental groups. CONCLUSIONS: Our data suggest that testosterone promotes calcium oxalate stone formation, and that dihydrotestosterone may be partially responsible for the exaggerated hyperoxaluria in EG-treated rats. Additionally, male sex hormones have a lesser influence on urinary citrate than oxalate.

The elbow joint is the most commonly dislocated-joint in the body except for the shoulder, and in children less then 10 years old, it is the most frequently dislocated articulation. The injury and the treatment are well described in most standard textbooks, but the characteristic findings and follow-up evaluations are not generally recognized. Authors have clinically analyzed 45 cases of traumatic fracture and dislocation of the elbow joint which are treated between January, 1975 and June, 1985 at the Department of Orthopedic Surgery, Wonju Medical College of Yonsei University. The results were as follows; 1. The age incidences were in even distribution except in the old ages where the incidence was low and the male to female ratio was 7: 3. 2. The major cause of the injury of the elbow was fall down (60%). 3. Posterior and posterolateral dislocations were about 60% of all cases. 4. Associated fractures were 35.6% of all the elbow dislocations, of which medial epicondyle fracture had the highest incidence. 5. Complications including ulnar nerve injury (3 cases), median nerve injury(1 case), radial nerve mjury(1 case), rupture of brachial artery(2 cases), recurrent dislocation(1 case) and calcification of ligament(2 cases) were observed. 6. Pure elbow dislocation occurred in 13 cases (28.9%). 7. The average immobilization period for patient with non-operative treatment (45%) and operative treatment(55%) were 7 days and 3 weeks, respectively, and much better results were seen in patients with non-operative treatment than in operative treatment and in shortened immobilization period.

Monitoring of the central venous pressure is a simple, relatively inexpensive method of assessing a patient's cardiac status, circulating blood volume, and vasomotor tone. The simplest way of checking the intrathoraeic location of the catheter tip is by observing oscillation of 2~4cmH2O in the manometer column, synchronous with respiratory cycle. Inaccurate measurements are often obtained by the misplacement of the central venous catheter tip, in addition to the other well-known complications. Radiographic identification of the catheter tip is essential to eliminate these problems. We experienced a case of arrhythmia which appeared upon misplacement of the central venous catheter tip, and confirmed its misplacement by radiographic study.

PURPOSE: To evaluate the usefulness of Gd-DTPA enhanced MR imaging in determining the metastatic lymph nodes in uterine cervical carcinoma. MATERIALS AND METHODS: Sixty nine patients with histologically proven cervical carcinoma underwent Gd-DTPA enhanced MR imaging. One hundred and thirty-eight pelvic regions(69 right,69 left) in 69 patients were analyzed for lymph node metastases. Pelvic lymph nodes were considered to be abnormal if they were greater than lcm in diameter and were enhanced on postcontrast T1 weighted images. RESULTS: Metastatic lymph nodes were found in 22 pelvic regions by surgicopathologic examinations. On MR imaging there were 14 true positives, 106 true negatives, 10 false positives and 8 false negatives. Gd-DTPA enhanced MR image had an accuracy of 86.9%, a sensitivity of 58.3%, a specificity of 91.4%, a positive predictive value of 58.3% and negative predictive value of 92.9% in evaluation of pelvic lymph node metastases. CONCLUSION: MR imaging with contrast enhancement may be useful in the evaluation of pelvic lymph node metastases in patients with uterine cervical carcinoma.

BACKGROUND: Vitiligo is an acquired disorder with destruction of melanocytes and is clinically characterized by depigmented patches of skin. The pathogenesis of vitiligo is still unclear, but melanocyte self destruction, neurohumoral factors, autoimmunity and inherent cellular defects have all been proposed as possible etiological factors. OBJECTIVE: The purpose of this study was to find out the differences in expression of HLA antigens among subtypes of vitiligo according to classification, onset and family history and then to disclose the pathogenesis of vitiligo in view of genetic and autoimmunological aspects. METHODS: We investigated HLA-A, B, C, DR in subgroups of 87 vitiligo patients according to type, onset, and family history. Results : 1. There were no HLA antigens with significantly increased frequency in vitiligo patients compared to the control group. 2. There was a significant increase in frequency of HLA-DRl2 in patients of non-segmental vitiligo with a family history ; an increase in frequency of HLA Cw2 in patients without a family history ; and a significant increase in frequency of HLA-DRl2 in all patients of non-segmental vitiligo compared to the control group.(p(c)<0.05). 3. The frequency of HLA-B63 was significantly increased in all patients of segmental vitiligo compared to the control group(p(c)<0.05), but there were no HLA antigens with significantly increased frequency in patients of subgroups of segmental vitiligo divided by the presence or absence of a family history of vitiligo. 4. The frequency of HLA-B54 was significantly increased in all vitiligo patients with a family history(p(c)0.05) but there were no HLA antigens with significantly increased frequency in all vitiligo patients without a family history. 5. There were no HLA antigens with significantly increased frequency in vitiligo patients subgrouped by age of onset (less or over 16 years) of disease. Conclusion : From the above results, we can assume that non-segmental vitiligo may have autoimmune mechanisms in the pathogenesis, as there was a significant increase in HLA-DRl2 in patients with non-segmental vitiligo.

Hydroa vacciniforme is a very rare photosensitivity disorder. The primary skin lesion is a vesicle or bulla which then heals with vacciniform scarring. We report a case of hydroa vacciniforme recurred after 3 years period of quiescence in a 20 year-old man who had had history of the disease from the age of two. The duplication of the natural lesion, clinically and histologically, was successfully made by artificial UV-A irradiation on the patient's back.
