PURPOSE:There is a clear sexual dimorphism in circulating concentration of leptin in adulthood. However, we don' know when such dimorphism begins and how much pubertal development influences on it. So we examined body composition and circulating concentrations of leptin according to Tanner stage(TS). METHODS:We examined 112 children(M; 56, F; 56, Age; 8.5-17 yr) to evaluate the relationship of leptin and body composition. Body composition was determined by bioelectric impedence measurements(BIA) and by anthropometry. Leptin was measured by human specific RIA. Leptin level was analysed according to TS, body mass index(BMI), fat mass(FM), and lean body mass. RESULTS:BMI and free FM was correlated with TS in both sexes. FM was closely correlated with TS in girls but not in boys(M; r=0.08, P=0.54. F; r=0.73, P>0.001). Leptin levels increased in girls with advanced TS(r=0.355, P<0.01), but decreased in boys(r=-0.339, P<0.01). A strong exponential relationship was observed for leptin levels with BMI, FM, and percentage body fat as determined by BIA. There was significant sexual dimorphism of leptin level at TS VI/V. Because leptin level was significantly related FM, leptin level was normalized to FM(Leptin/FM). Leptin/FM of females(0.67+/-.27 ng/mL/kg) was also significantly higher then that of males(0.31+/-.15 ng/mL/kg)(P<0.001). CONCLUSION: These data suggest that plasma leptin levels increase in girls and decrease in boys after TS II as pubertal development proceeds; they show a significant gender difference, especially late puberty, even after adjustment for FM. Sexual dimorphism in leptin during puberty reflects not only differential changes in body composition but also different leptin resistance; reference ranges of leptin could be modified by TS and gender.

Extraskeletal chondromas are relatively uncommon benign cartilaginous tumors of the soft tissue and well known to pose a considerable diagnostic problem because of histological variations including the immature appearance of their tumor cells. Recently, we have experienced a case of extraskeletal chondroma mimicking benign chondroblastoma. The patient was a 47-year-old woman who complained of a painful subcutaneous swelling on the radial aspect of 4th proximal interphalangeal (PIP) joint in the left hand for 6 months. Radiologic examination of the 4th finger revealed a 1cm-sized soft tissue mass. Histologically, the tumor was characterized by a lobulated mass which was composed of dense proliferation of chondroblast-like cells admixed with a few multinucleated giant cells of osteoclastic type. However, there were focal areas of typical chondroma which showed lace-like intense calcification around the differentiated chondrocytes.

The incidence of contrast media extravasation has been increasing gradually. Most contrast media extravasations only can cause pain, swelling and erythema. However, in more severe cases, skin necrosis, ulceration, or compartment syndrome may occur, often necessitating a surgery. Early diagnosis and treatment should be established on the spot in order to avoid such a severe damage. We present a case of 42-year-old woman with a compartment syndrome in the right upper extremity caused by extravasation of computed tomography contrast media.

We report the clinical features in one patients with episodic positional vertigo and apogeotropic direction changing horizontal positional nystagmus that does not fatigue, beating to the right with the head turned to the left and beating to the left with the head turned to the right. This syndrome probably represents a horizontal semicircular canal variant of benign positional vertigo. Free-floating debris and Cupula attached debris in one horizontal semicircular canal may explain many of the clinical and oculographic findings.

Crypt glandular infection theory is accepted as an explanation of anal fistula's major cause. However, the pathogenesis of an anal fistula in Crohn's disease is different from that of a conventional anal fistula because a Crohn's anal fistula is caused by ulceration which, in turn, is caused by transmural inflammation of the rectal wall due to Crohn's disease. The difficulty with operating on anal fistulas in Crohn's disease lies in the fact that healing of the wound is inhibited because of continuous inflammation of the anorectal tissue due to Crohn's disease. Hence, there is a high possibility of incontinence due to sphincter muscle injury. Especially, because almost all Crohn's disease patients have frequent defecation and diarrhea, the patients will suffer more if incontinence occurs. Nowadays, even with increased understanding of the etiology of Crohn's disease, new medications, and aggressive surgical approaches, the result of treatment is still not satisfactory. Recently, since Korean eating habits have changed to include more western-style food in the diet, inflammatory bowel disease, such as Crohn's disease, is expected to increase. Consequently, the number of cases of anal fistulas in Crohn's disease is also expected to increase. The authors reviewed 20 confirmed cases of anal fistulas in Crohn's disease, which were treated from January 1993 to December 1995 at Song-Do Colorectal Hospital. The results are as follows: 1) Anal fistulas in Crohn's disease were present in 20(0.6%) of the 3378 cases of anal fistulas treated during the time period considered. 2) The male to female ratio for these 20 cases was 2: 1, and the most Prevalent age group was the 3rd decade, followed by the 2nd decade, the 4th decade, and the 5th decade in that order. 3) Three cases of anal fistulas whose origins could be explained by crypt glandular infection theory and which did not involve the rectum healed, although the healing was delayed. 4) Seventeen cases of anal fistulas whose origins could not be explained by crypt glandular infection theory and which involved the rectum did not heal after the operation. he results of the study show that anal fistulas whose origins can be explanined by crypt glandular infection theory and which do not involve the rectum can be cured by conventional fistula surgery. However, perirectal fistulas whose origins can not be explained by crypt glandular infection theory and which involve the rectum do not heal. Because there is the possibility of incontinence after a conventional operation, it is suggested that, in the cases of perirectal fistulas in Crohn's disease, better results, although not completely satisfactory, can be obtained by long-term seton drainage and diversion colostomy.

A total of 56 subjects with multiple nematode infections with T. trichiura, Ascaris, hookworms and Enterobius were treated with oxantel and pyrantel pamoate mixture in a paratable suspension(50 mg of each per ml). A single dose of 10 mg per kg body weight in each cured 100 per cent of 54 subjects with Ascaris, 97.1 per cent of 35 subjects with hookworms, 77.8 per cent of 36 with Enterobius and 73.2 per cent of 56 subjects with T. trichiura infestation. The mean egg per gram stool reduction rate in T. trichiura infection was 91.9%. Of the 31 subjects infected with Ancylostoma doudenale 96.8% were cured with a single dose and 4 infected with Necator americanus showed a 100% cure rate with a similar daily dose on 3 consecutive days. Side effects were few and mild. There was no clinical or laboratory evidence of drug toxicity. These findings show a single dose of oxantel and pyrantel pamoate mixture to be a highly effective and acceptable treatment for multiple infections with these nematodes.

Clinical study was carried out on the 64 hemodialysis patients(HD) with chronic renal failure who had been treated from December 1992 to July 1993 in Yeungnam University Hospital. The following results were obitained. In hematologic parameters, MCH was 28.8±2.0pg, and MCV was 92.4±4.7fl. Result revealed normochromic and normocytic anemia. Mean values of serum ferritin were 657.4±292.0ng/ml in men and 511.5±370g in women. Mean values of serum iron were 145.5±63.7µg/dl. Mean values of transferrin saturation was 61.6±28.4%. Serum frerritin, serum iron and transferrin saturation were higher in HD group than normal reference. In erythropoeitin treatment group, Hb and Hct were significantly higher than non-erythropoietin treatment group. Amount of transfusion was significantly higher in non-erythropoietin treatment group than erythropoeitin treatment group(p<0.05). Values of iron, transferrin saturation were significantly higher in abnormal liver function test(LFT0 hemodialysis group than normal LFT group(p<0.05). Transfusion amounts revealed positive correlation with ferritin(r=0.4675), transferrin satruation (r=0.3823) and iron(r=0.3386) (p<0.05).
