Two cases of carcinoid tumor of the uterine cervix were reported with emphasis on the histologic, cytologic, histochemical and electron microscopic appearance of tumor cells. Based on the light microscopic findings, one case was a well differentiated carcinoid with acinus formation, and the other was a poorly differentiated anaplastic type, being composed of small cells similar to those of oat cell carcinoma of the lung. Both tumors demonstrated scattered argyrophilic cells on Grimelius stain, and contained neurosecretory granules on electron microscopy. They were in stages II b and IV, respectively, at the time of presentation. The latter patient was treated with vinblastin, platinol and bleomycin, but died in 9 months after the initial diagnosis. The former was lost to follow-up study. Importance of distinction between this highly malignant tumor and other varieties of cervical cancer was emphasized.

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.

5.Ultrasonography in Sternoclavicular Joint Posterior Dislocation in an Adolescent: A Case Report.

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.

6.Surgical Treatment for the Shoulder Joint in Rheumatoid Patients.

Rheumatoid arthritis (RA) is a systemic disease with medication as the treatment of choice. However, surgical treatment is recommended when no improvement is noted despite aggressive conservative treatment. Synovectomy provides desirable outcomes for RA patients in the early stage with a glenohumeral joint of Larsen grade II or less; conversely, arthroplasty is recommended for patients with a glenohumeral joint of grade III or higher. RA patients often have attenuation and dysfunction of the rotator cuff, and reverse shoulder arthroplasty has been proven to provide favorable outcomes in some patients. RA is often complicated with osteoporosis and bony deformity; therefore, close attention is necessary to prevent fractures during shoulder arthroplasty.

A new method of urinary diversion via Skinner`s modification of Koch continent ileal reservoir was tried. With this method continence with storage of urine under low pressure is well maintained so that no external applicances are necessary. Ileorenal reflux is also prevented with this nipple forming technique. From May l986 to September l986, 4 patients underwent urinary diversion that included creation of a modified Koch pouch by Skinner. Previous urinary diversion was by ureterocutaneous diversion in 1 patient. A total of 3 patients underwent radical cystectomies for bladder cancer In 1 patient, simultaneous urethrectomy was done because of carcinoma in situ in the urethra. There were no operative mortalities. All patients are continent and without reflux to the upper urinary tract. The volume capacity of pouch is more than 400ml. The pouch is emptied by self-catheterization every 4 to 6 hours during the day and once at night. Postoperative follow-up presently is short and it is impossible to check late complications. Although preliminary, this clinical trial suggests that the quality of life for patients can be improved markedly by the modified Koch continent ileal reservoir.
