Purpose: This study examined the changes in the body mass index (BMI) and the effects of BMI on the knee function and risk factors for an increase in BMI after total knee arthroplasty (TKA) in Asians. Materials and Methods: A prospective observational study was conducted on 100 cases of TKA performed by one surgeon. Obesity was defined as BMI ≥25 kg/m 2 . The BMI and Knee Society Score, consisting of the Knee Score and Function Score, were measured on the day before surgery and one year after surgery. Results: The BMI decreased or was maintained in 34 cases (34%) and increased in 66 cases (66%) one year after surgery. An increase in BMI of 5% or more was considered a clinically significant increase in BMI and occurred in 28 cases (28%). The patients with an increased BMI by more than 5% showed a significantly lower knee function score. The age and preoperative function score were significantly associated with an increased BMI by more than 5%. As the age increased by one year, the odds ratio at which the BMI would increase by more than 5% one year after surgery was 0.905. Moreover, as the preoperative function score increased by one point, the odds ratio that the BMI would increase by 5% one year after surgery was 0.902. In other words, a younger preoperative age and a lower preoperative function score mean a higher risk of a more than 5% postoperative increase in BMI. Conclusion The BMI increased by more than 5% one year after surgery in 28% of the TKA patients examined. They had a lower functional score. The risk factors for a more than 5% increase in BMI after TKA were young age and a low preoperative function score. Therefore, surgeons should educate patients, particularly those who are young or have a low preoperative function score, so that the patient’s BMI would not increase after surgery.

We conducted a study to compare the effects of Healon(R) and BioLon(R), which are sodium hyaluronates made by different raw materials, on rabbit eyeballs after intracameral and intravitreal injections. In the intracameral-injection group, aqueous humor was replaced with 0.2 ml of Healon(R) or BioLon(R), and in the intravitreal-injection group. 0.4 ml of Healon(R) or BioLon(R) was injected after the removal of the same amount of vitreous. Slitlamp and indirect ophthalmoscopic examination, measurement of IOP, and measurement of corneal thickness were performed preoperatively and at 2hours, 24 hours, 3 days, and 7 days postoperatively. Histopathologic examinaion was done at 7 days postoperatively. No group had significant differences in all tests(p>0.05) and the findings were normalized within 7 days. These results indicated that there were no significant differences between the Healon(R) and BioLon(R) groups in the effects on rabbit eyeballs after intracameral and intravitreal injections.

Miescher syndrome comprises congenital acanthosis nigricans, hypertrichosis, failure to thrive and short stature, dysmorphism especially of the jaws and oral cavity, insulin-resistant diabetes mellitus, and a characteristic general appearance. This report concerns a rare case of 12-year-old girl having insulin resistant diabetic mellitus with Miescher syndrome. The relevant literature was reviewed.

We report a case of plexiform neurofibroma developed under the overlying speckled lentiginous nevus, which occurred in a 20 year-old man. In this patient and his family no other signs of von Recklinghausens disease were found. Discussion is focussed on the fact that both plexiform neurofibroma and speckled lentigmous nevus, which represent a defect in the neural crest, occurred in the same area of the skin.

Leiomyoma Cutis is an unusual benign tumor of smooth muscle derivecl either from the arrector pili muscle, from the media of blood vesseles, or from smooth muscles of scrotum, labia or nipple. Two casea of leiomyoma cutis confirmed by H&E stain and Massons stain is presented, one with lesion on the left thigh and the ather with lesion of the left ankle. The first case was a 49 year-old female with solitary pinhead sized subcutaneous firm mass with intermittent pain and tenderess for 10 months, The second case waa a 36 year-old female with painful solitary peanut sized firm nodule which had pinkish center of 1 year duration.

Perifollicular fibromas are very undsual adnexal tumor of the skin. Clinically, they are small firm akin colored or pinkish papules and usually located on the face and neck. We report a case of perifollicular fibroma which occurred in a 30-year-old woman, who had asymptomatic multiple small skin colored papules on the right side of her face for about 20 years. On physical examination, the papules were ferm and non-tender. The biopsy specimen demonstrated concentric proliferation of fibrous tissue surrounding hair follicles ad the collagen fibers within concentric fibrous sheaths surrounding hair follicles stained green with Masson's trichrome stain, which were quite typical for perifollicular fibroma. Because we could not find any epithelial proliferation in the serial sections, fibrofolliculoma could be ruled out. The skin lesions were removed by electrodesiccation and followed up for 5 months without recurrence.

PURPOSE:The prevalence of childhood obesity has been increased rapidly, associated with high morbidity of dyslipidemia, cardiovascular risk factors and insulin resistance/hyperinsulinemia. Hyperinsulinemia in obese children may depend on either increased insulin secretion or decreased insulin clearance. We investigate whether insulin secretion and clearance are different between obese and normal weight children. METHODS:The body mass index(BMI), fasting serum glucose, insulin and C-peptide levels were measured in 101 children(52 obese children and 49 non-obese controls) in Ansan area, from 6 to 14 years old. Fasting serum C-peptide/insulin ratio, insulin/glucose ratio, homeostasis model assessment(HOMA) were calculated and compared between obese and control group. RESULTS:The fasting serum insulin and C-peptide levels were significantly higher in obese group than in controls. The C-peptide/insulin ratio was significantly lower and insulin/glucose ratio was significantly higher in obese group than in controls. There were positive correlations between BMI and fasting serum insulin level, fasting insulin/glucose ratio and HOMA. The prevalence of hyperinsulinemia is higher in obese adolescents than in controls. CONCLUSION: Our findings suggest that increased insulin secretion and decreased insulin clearance may contribute to hyperinsulinemia in obese children.

We report a case of secondary anetoderma due to pilomatricoma. A 15-year-old girl presented with a soft, 1.5 × 1.5cm in size, atrophic, pinkish and bulged-out lesion overlying the palpable subcutaneous mass on the left upper arm for several months. Histologic examination revealed the reduced number of dermal elastic fibers overlying a typical pilomatricoma.
