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 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.

We report herein a human sparganosis that presented confusing features in aspect of its correct identification, The patient was 35-year-old man who had a past history of eating fried frogs since 3 years prior to his first admission in 198I. Three mature Sparganum mansoni and 69 encapsulated spargana pieces were excised from his left inguinal area, left thigh and scrotum by three consecutive operations in 19 months. The encapsulated spargana were irregular in shape and size and mummified. They were identified histopathologically as degenerated spargana by no sexual organs and many calcareous bodies in the parenchyma. Differentiation of our case from proliferating sparganosis caused by Spargarrum proliferum was discussed.

7.Effects of Seminal Vesiculectomy on Structure and Function of Testes and Epididymides in Vasectomized Rats.
Korean Journal of Urology 1981;22(3):243-249
Vasectomy has become increasingly popular as a method of male fertility control in humans because it is simpler than other methods for a woman. In spite of numerous studies on the effects of vasectomy on reproductive organs and their functions over varying periods of time, a lot of problems remained such as histological and functional changes of the reproductive organs. Recently the vasovasostomy has been developed under the requiring of succeeding an offspring or other problems, but it has not proved to be consistently i reliable in reversing previously performed vasectomies. Results in most of the investigations indicate that sperm is present in the ejaculate of 95 per cent of the operated cases. However, pregnancy occurs in only 40 per cent of the partners. It also has been demonstrated that antisperm antibodies occur in the serum of approximately half of the patients who have undergone vasectomy, and the immunologic consequences of vasectomy have been investigated extensively in a variety of laboratory animals and in man, but opinions vary as to whether such antibodies may be responsible for infertility after vasectomy. A second, also less information about phenomenon is formation of antisperm antibodies. Some have postulated that sperm granuloma formation is a mechanism for sensitization of the host to his own sperm, but other have concluded that sperm granuloma formation does not necessarily result in humoral sperm autosensitization. In an attempt to observe the effects of seminal vesiculectomy on structure and function of the testes and epididymides in vasectomized rats, this study was performed. The results as follows: 1. Spermatogenesis in the testicular tissue seems to be much inhibited in vasectomized rats after seminal vesiculectomy. 2. Absorptive activity of the rat epididymides may be accounted to be decreased after seminal vesiculectomy. 3. Sperm granuloma occurred around the epididymides of 90 per cent in the vasectomized rat after seminal vesiculectomy: Large one was measured by 2.5 x 1.5cm., but 50 per cent in the vasectomized rat with large one measured by 1.5 x 0.6cm. in size.

A 53-year-old man developed some erythematous follicular macules accompanied with tingling sensation on both shoulders. Histologic finding showed a dense lymphocytic infiltrate around the infundibular portion of the follicle, where separation of the dermoepidermal junction was seen. The insect, obtained from the skin lesion, was identified as a larva of an Ap- hid

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.

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.
