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.

BACKGROUND: At least 30 per cent of diabetics, which is said to comprise over 3% of general population in Korea, have one or more cutaneous complications during the course of the disease. These skin changes may be the consequences of microangiopathy, arteriosclerosis, direct metabolic disturbances and/or the sequelae of chronic therapy. OBJECTIVE: We tried to observe certain cutaneous and nail changes in diabetics and to relate them with systemic complications, blood sugar level and duration of diabetes. METHODS: During the period of 12 months from March, 1992 to February, 1993, a total of 1858 outpatients diagnosed as diabetes mellitus at Eulji General Hospital were examined. RESULTS: The cutaneous manifestations are observed in 79.5% of diabetics examined and cutaneous infections are the most prevalent(52.3%). Pruritus(p<0.01), anogenital pruritus(p<0.01), peripheral dedema(p<0.05) are more common in females and infections, shin spots, finger pebbles(p<0.01) are more common in males. Systemic complications are observed in 50.7% and the cutaneous manifestations are observed more frequently in patients with systemic complications(p<0.05). Shin spots, diabetic foot, peripneral edema diabetic bullosis are observed frequently associated with systemic microangiopathic complications such as retinopathy, nephropathy and neuropathy(p<0.01). There is a significant correlation between blood sugar level and fungal infections and anogenital pruritus(p<0.01). The frequencies of shin spots, diabetic foot and diabetic bullosis increase with the length of time diabetes has been present. Nail changes are observed in 39.6% of diabetics and onychomycosis is the most frequent(34.5%). CONCLUSION: It is suggested that cutaneous shgns especially fungal infections in diabetics are on the increase in Korea. A variety of skin conditions are encountered with diabetes mellitus and the dermatologist may be able to make a significant contribution in the control of diabetes mellitus by identifying skin signs and conditions as diabetic complications.

One of a fairly common cause of painful hips in children is the transient synovitis which subcide in short time by bed rest. This transient synovitis is also called as observation hip, irritable hip, coxitis serosa seu simplex, transitory hip arthritis, transitory coxitis, acute transient epiphysitis, toxic synovitis, and intermittent hydrathrosis etc. It is not clear what is the exact cause of transient synovitis but many authors agree infection, trauma and allergic conditions can be cause of that disease. The disease is of interest, not because it is a disabling condition, but because of the difficulties encountered in differentiating it from more serious disease of the hip such as Legg-Calve-Perthes disease, tuberculosis, osteomyelitis and etc. Of the 67 cases so diagnosed at the catholic medical college from 1975 to, 1980, 30 were reviewed and reported. Following observation were made: 1. The main symptom was pain of sudden onset in the region of the hip joint with a limp on the: affected side. 2. The patients mean age was 7.4 yrs and the sex ratio of boy & girl revealed 1. 7:1. 3. Radiological abnormalities of the soft tissue shadow of the affected hip joint was noted at 24 cases (80%), among them the gluteal sign(50%) are more prominent than others Bone scanning with Tc was performed at 13 cases. Increased uptake density of radio-active isotopes found at 6 cases (46%). 4. The treatment was conservative including bed rest, skin traction on the affected leg, non weight bearing, antibiotics and anti-inflammatory drug. 5. Two hips among them revealed later as s Legg-Calve-Perthes disease and tuberculous arthritis of hip joint.

STUDY DESIGN: A retrospective study. OBJECTIVES: To assess the relationship between surgical outcomes and preoperative MRI findings, a retrospective review was conducted on the surgical outcomes depending on the preoperative MRI findings including type of herniation and Modic changes. SUMMARY OF LITERATURE REVIEW: In most reports, the patients that have large disc herniation were expected to have improved surgical outcomes. However, there have been controversies regarding the outcomes and Modic changes. MATERIALS AND METHODS: The retrospective review was conducted in 82 patients who underwent a discectomy for single level lumbar disc herniation. The average follow-up period was 34.2 months. Among their preoperative baseline MRI measurements, the stage of disc herniation, degree of nerve root compression, degree of dural sac compression, and Modic change of vertebral endplate were evaluated for the subsequent comparison between the preoperative and postoperative changes and ODI score. RESULTS: Patients with extrusion or sequestration type showed significant improvements compared to the patients with protrusion type disc herniation. By degree of nerve root compression, patients with root compression showed significant improvements compared to the patients who had contact type. The degree of dural sac compression revealed no correlation with changes in the ODI score. 23 of the 82 patients, the preoperative MRI showed a Modic change. Compared to the group who did not show such a Modic change, they turned out to be unrelated to the preoperative and postoperative changes in the ODI score. CONCLUSIONS: Patients who had extrusion or sequestration type disc herniation showed a better clinical improvement than protrusion type. Patients with compression type root lesion showed better clinical improvement than contact type root lesion. No correlation was noted regarding the outcomes of the surgical treatment and degree of dural sac compression or Modic changes.

Behcet's disease is characterized by recurrent orogenital ulcers and ocular and cutaneous inflammatory lesions. Cardiovascular involvement, which may be artrial or venous, is rare but carries a particularly poor prognosis. One of the known vascular complications of Behcet's disease is aneurysm formation or venous thrombosis. We recently experienced a Behect's disease with multiple arterial aneurysms and thrombosis and report this case with review of literatures.

We report computed tomography (CT) and magnetic resonance (MR) findings of a patient with polyostotic Paget disease and multicentric giant cell tumor (GCT). Brain CT scan showed widening of diploic space, cortical thickening and enhancing soft tissue mass in occiput with underlying calvarial destruction. Ill-defined soft tissue masses were also detected in maxillary sinus and buttock with underlying bony destruction on CT. MR image showed multifocal nodules in wide diploic space with low signal intensity on T1 -weighted image and bright signal intensity on T2-weighted image. Mass in occiput showed homogeneous hypointensity to bone marrow on T1-weighted image and homogeneous iso- intensity on T2-weighted image. Multiple nodules in diploic space and occipital mass showed contrast enhancement following administration of Gd-DTPA. Biopsy was performed at scal p, maxillary sinus and buttock, and histologic analysis revealed GCT.
