anserine folliculosis (Padilha-Gonqalves, 1977) is a skin disease occurring on the limited areas of the skin receiving prolonged friction and/or pressure by the other part(s) of the naked skin of the patient. Padilha-Goncalves named traumatic anserine folliculosis by stressing the etiologic factor, the pressure and friction, the goose skin appearance and the follicular nature of the basic skin lesions. A 7-year-old girl developed typical features of traumatic anserine folliculosis on the chin who had the habit of resting the chin on the right knee for 5 years while painting.

The prevalence of diabetes mellitus(DM) is increasing in Korea and is estimated at 7~8%. This high prevalence is most likely the result of a complex interaction between genetic and environmental factors. The lifestyle and diet of the Korean population have changed significantly during the last several decades. In general, the Koreans have become more sedentary and they consume westernized diet. In addition to the increase of prevalence, the clinical characteristics of DM in Korea are somewhat different from those in Western countries. The incidence rate of type 1 DM in Korea is one of the lowest reported in the world. There are many patients with atypical type 1 or type 2 DM, initially classified into type 2 DM but requiring insulin eventually. There are many patients with non-obese type 2 DM, and many of them lose weight significantly during the course of disease. In addition, some patients with type 2 DM have autoantibodies to the beta cell-specific antigen. The defect in insulin secretion is prominent in non-obese subjects with impaired glucose tolerance or early phase of type 2 DM. The Korean patients with type 2 DM have a markedly decreased beta cell mass. The impaired insulin secretion may play a role in the pathogenesis of non-obese type 2 DM in Korea. Of note, similar features are also observed in Japanese patients. Unfortunately, there are few studies that evaluated the pathogenesis and clinical characteristics of Korean patients with DM, particularly in a cohort-based prospective manner.

Pregnancy is a complex metabolic state involving dramatic alterations in the hormonal or cytokine environments (increases in estrogen, progesterone, prolactin, cortisol, human chorionic gonadotropin, placental growth hormone and human placental lactogen, TNF-alpha, resistin, leptin, and a decrease in adiponectin) as well as an increasing burden of fuel utilization by the conceptus. Metabolically, the first trimester is characterized by increased insulin sensitivity and lipogenesis. The second and third trimesters, in contrast, are characterized by insulin resistance and increased lipolysis.

PURPOSE: To determine the accuracy of MRI on postoperative pain syndrome (POPS), including early complications such as hematoma or infection. MATERIALS AND METHODS: Of the 54 patients with the POPS, we analyzed pre-operative MRI findings compared with operative findings on 39 patients, excluding nonunion, instability, metal failure and pseudarthrosis, who underwent an operation for POPS from December 1994 to June 1997. There were 25 men (64.1%) and 14 women (35.9%), aged from 16 to 68 years (average 44.5 years). They were divided into 5 subgroups and calculated for sensitivity, specificity and positive predictability. RESULTS: MRI accuracy in recurred disc was 84%, scar adhesion, recurred or developed stenosis, infection and hematoma was 100% for each overall accuracy of MRI was 93%. Average interval of reoperation in POPS was 3.2 years. In 21 cases (53.8%), symptoms persisted without pain-free interval after first operation. CONCLUSIONS: Early complications, including hematoma and infection, are easily detected with MRI. Especially if patient complains of severe leg pain or neurologic deficit, MRI is a good diagnostic tool. MRI is a useful method for evaluation of most cases of POPS, but it is limited in evaluating recurred disc or scar adhesion only in T1, T2 weighted image. Therefore, Gd-DTPA enhancement is necessary for an accurate diagnosis.

The global incidence of diabetes mellitus is increasing. Patients with diabetes are at increased lifetime risk of developing foot ulcers a major and increasing public health problem associated with morbidities, impairment of quality of life and increased management costs. As > 85% of amputations are preceded by an active foot ulcer in patients with diabetes ulcers and amputation are considered together in this report. We examine the incidence of foot disorders in South Korea using disease-classification codes included on health insurance claim forms and data collected during a 5 year observational study in a university hospital. The annual incidence of diabetic foot disease is 1.0~1.2% in Korea. However, Korean epidemiological studies describing the clinical and surgical characteristics of diabetic foot wounds are lacking. The evaluation and treatment of diabetic foot ulcers should be implemented in prospective cohort studies as soon as possible.

STUDY DESIGN: A retrospective study. OBJECTIVES: We report the efficacy of the entry point and approach angle of a working cannula using preoperative prone abdominal computer tomography (PACT). SUMMARY OF LITERATURE REVIEW: To date, there are no reports on the entry point and approach angle of a working cannula when performing transforaminal percutaneous endoscopic lumbar discectomy (TPELD) with consideration of the individual anatomic variations and characteristics of herniated disc and surgical instruments. MATERIALS AND METHODS: Cases of herniated intervertebral discs from L4-5, who have previously undergone PACT before TPELD, were included. A total of 25 patients were observed over a 1 year period. The entry point and approaching angle of the working cannula with PACT were calculated, and the results were applied to the TPELD. The clinical results were assessed 1 month after surgery using the VAS, ODI and MacNab criteria, and were confirmed by a radiology and MRI examination. RESULTS: The preoperative measured data using PACT showed that the mean approaching distance and mean approaching angle of the working cannula were 12.4 cm and 75.4 degree, respectively. The VAS improved from a mean of 8.1 preoperatively to a mean of 2.3 12 months after surgery. The ODI improved from a mean of 59 preoperatively to a mean of 24 at 12 months after surgery. According to the MacNab criteria, all patients were classified as either excellent and good during the follow up periods. The extruded disc of all patients had been well removed according to the MRI scan performed 1 month after surgery. CONCLUSIONS: The scientific approach method using PACT based on the characteristics of patients and surgical instruments can be performed easily and accurately, and access and decompress the extruded disc directly.

We report here on a case of metachronous second primary non-Hodgkin's lymphoma (NHL) that was diagnosed 6 years after performing subtotal gastrectomy for treating early gastric cancer (EGC). The subtype analysis revealed mantle cell lymphoma (MCL) of the blastic variant with a leukemic presentation, which was composed of mixed small and medium-sized cells. The immunohistochemical staining for cyclin-D1 was positive. The cytogenetic study revealed t(4;6). In Korea, the risk of developing a second primary cancer following gastric cancer was reported to be less than 3.4%, and NHL comprised less than 6.3% of this second primary cancer. Furthermore, MCL represents about 2% of all lymphomas in Korea. To the best of our knowledge, this is the first report of metachronous primary MCL with a leukemic presentation following curative resection of EGC.

Medullary carcinoma of the thyroid gland(MTC) constitutes approximatesly 3% to 10% of all malignant thyroid tumors. It appears in both familial and sporadic forms. Metastases are frequently present at diagnosis and are resistant to chemotherapy and radiotherapy. Surgical resection of the primary tumor and the metastases is the mainstay of treatment. Although MTC can be detected by elevated serum calcitonin, localization of residual or metastatic foci may be difficult. Many scintigraphic methods have been used for identification of the residual tumor or metastasis. However, most of them have either low sensitivity or low specificity. MTC frequently secretes somatostatin and may express somatostatin receptors. Recently, somatostatin-receptor imaging has been known to be useful for the detection of residual and recurrent medullary thyroid carcinoma. A 25 year-old woman who was dignosed as medullary carcinoma by biopsy of thyroid mass is presented. Thirteen years ago, she underwent left thyroidectomy due to thyroid cancer(MTC). Laboratory tests revealed an increase in the levels in serum CEA(CEA=557.6 ng/ml) and calcitonin(calcitonin= 720 pg/ml). The second patient, a 30 year-old female, complained of a palpable mass in the left anterior neck. Ten years ago, she underwent a right lobectomy of thyroid gland due to adenomatous goiter. Laboratory tests revealed an increase in the levels in serum CEA(CEA=617 ng/ml) and Calcitonin (Calcitonin=2,300 pg/ml). In both cases, pre- and postoperative In-111 pentetreotide scintigraphy were done and compared with "'I scintigraphy. In-111 pentetreotide scan may be useful for the localization of residual or metastatic medullary thyroid carcinoma. Further study is warranted to define the sensitivity and specificity of the technique.

Background: A lifelong thyroxine therapy is indicated in all patients who have hypothyroidism as a result of autoimmune thyroiditis. However, it has been reported that some hypothyroid patients with autoimmune thyroiditis have spontaneous remission with restriction of iodine intake instead of thyroxine therapy. The purpose of study was to investigate how many hypothyroid patients with autoimmune thyroiditis can recover from hypothyroidism with restriction of iodine intake instead of thyroxine therapy and which factors predict recovery from hypothyroidism. Methods: We studied 64 patients with autoimmune thyroiditis(goitrous autoimmune thyroiditis 56, atrophic autoimmune thyroiditis 8). Thyroxine therapy was discontinued in patients with goitrous autoimmune thyroiditis on the way(group 1, n=32) or from the beginning(group 2, n=24) and atrophic autoimmune thyroiditis on the way(group 3, n-8). All patients were asked to avoid iodine-rich foods and thyroid function was monitored every one to two months for up to 35 months. Serum T3, T4, TSH concentrations, antithyroglobulin and antimicrosomal antibodies were measured by radioimmunoassay(RIA). TSH binding inhibitor immunoglobulin(TBII) was measured in serum using radioreceptor assay. Two hundred micrograms of thyrotropin releasing hormone (TRH) were given as intravenous bolus and TSH levels were measured in blood samples taken at 0, 30, and 60 minutes. All values were expressed as mean+-SEM. Statistical analysis was done with paired or non-paired t-test, ANOVA, and the Chi-square test. Statistical significance was defined as p-value below 0.05. Results: Thirteen(40.6%) of 32 patients in group 1 remained euthyroid after 12-35 months of discontinuation of thyroxine therapy. The other 19(59.4%) patients in group 1 had recurrences of hypothyroidism within 3 months after discontinuation of thyroxine therapy. In 11(45.8%) out of 24 patients in group 2, serum TSH concentrations declined below 5 mU/L within 3 months without thyroxine therapy. The other 13(54.2%) patients in group 2 remained hypothyroid till 2-16 months and the thyroxine was given. In contrast, all 8 patients in group 3 had recurrences of hypothy- roidism within 3 months after stopping thyroxine therapy. When we compared the recovered patients of goitrous autoimmune thyroiditis with the non-recovered patients of goitrous autoimmune thyroiditis, regardless of thyroxine therapy from the beginning, age at onset of disease of the 24 recovered patients was significantly younger than the 32 non-recovered patients(30.1+2.0 years vs. 40.2+ 2.4 years; p=0.004). Concl#usion: These findings suggest that 42.9% of hypothyroid patients with goitrous autoim- mune thyroiditis remain or become spontaneously euthyroid with restriction of iodine intake instead of thyroxine therapy. Young age may be a predicting factor of recovery from hypothyroidism in goitrous autoimmune thyroiditis.

In Langerhans cell histiocytosis, diabetes insipidus is the most common endocrinologic complication. We experienced a case of Langerhans cell histiocytosis, involving pituitary stalk and lung. The patient was a 43 year old male with complaint of polyuria and polydipsia. The water deprivation test was carried out to confirm the diagnosis of diabetes insipidus. We found multiple small cysts and nodules in HRCT of lung, and diagnosed Langerhans cell histiocytosis by transbronchial lung biopsy, The patient was managed conservatively with DDAVP nasal spray. The polyuria,polydipsia was relieved completely. After that, we follow up and observe closely the patients lung and pituitary lesion.
