We experienced a boy manifesting sexual precocity with unilateral testicular tumor, who was finally diagnosed as CAH with 21-hydroxylase deficiency. Initial laboratory findings were compatible with peripheral precocious puberty. Ultrasonogram for testes showed heterogenous high echoic mass in the right testicle. Radical orchiectomy was performed and its pathology revealed benign Leydig cell tumor without Reinke crystal. But, testosterone was not decreased after 1 month of surgery. Second laboratory exam revealed increased DHEA-S and 17-hydroxyprogesterone. Finally, this case was recognized as CAH(simple virilizing type) with unilateral testicular adrenal rest tumor. In conclusion, CAH should always be considered during etiologic study for the male sexulal precocity even with unilateral testicular tumor.

Central nervous system impairment is common in diabetic patients, even in the early stages of the disease, and could be associated with peripheral neuropathy. The aims of this study were to prospectively investigate central nerve conduction in young adults with type 1 diabetes using pattern-reversal visual evoked potentials (PRVEP) and to determine how those results were related to clinical risk factors and the parameters of the peripheral nerve conduction study (NCS). A total of 36 type 1 diabetic patients (15 males) 5-24 years of age (mean 14.5 ± 4.7) underwent PRVEP and NCS annually for five years. For comparison, 39 healthy age and sex matched individuals (mean 14.8 ± 5.0) were evaluated as the control group. The P100 latencies of the PRVEP were prolonged at the study entry in the patients compared with the controls (p< 0.001). Significant correlations were not found between any of the parameters of PRVEP and the glycosylated hemoglobin levels; however, the changes in the parameters of the peripheral NCS were well correlated with metabolic control. The latencies and amplitudes of the P100 were not related to the majority of the parameters of the NCS. A prolonged PRVEP latency may be a sign of optic pathway dysfunction, which begins before apparent diabetic retinopathy. Poor glycemic control proved to be an important risk factor over the 5 years in terms of its relation to the development of peripheral neural pathway abnormalities. However, once central conduction was delayed, its changes were poorly related to diabetic control and the attributes of the peripheral nerve conduction study over the 5-year follow-up.

PURPOSE:The natural course of Hashimoto' thyroiditis (HT) is so dynamic that the disease progresses to overt hypothyroid or spontaneous recovery. The authors reviewed the clinical course of this disease and analysed the possible predicting factors regarding remission. METHODS:Thirty nine patients with HT (38 girls and 1 boy) were studied retrospectively. Of these patients, 30 were followed for more than 2 years. The possible remission factors were analyzed at initial diagnosis and during follow-up period. RESULTS:The mean age at the diagnosis was 11.8+/-.1 years. Initial thyroid function was euthyroid in 38.5%, compensated hypothyroid in 35.9%, overt hypothyroid in 23.1%, and hyperthyroid in 2.6% of patients. Antithyroglobulin antibody (ATA) was positive in 94.7%, and antimicrosomal antibody (AMA) was positive in 74.4%. The overall remission rate was 53.3% during the follow-up period (51+/-7 months). Initial goiter size, thyroid function status, and autoantibody titer had no relation to the remission rate statistically. Follow-up autoantibody titers in remission group were marginally lower than those in nonremission group (P<0.1), and follow-up AMA titer was significantly higher than initial titers in nonremission group (P<0.05). CONCLUSION: We could not find any predictable remission factors from the initial clinical and autoantibody status. But, during follow-up period, patients with lower autoantibody titers showed slight higher remission, and those with increasing AMA titer showed less remission. Above results suggest that we should monitor antithyroid antibody titer as well as thyroid function regularly.

BACKGROUND: Early detection of neuropathy may prevent further progression of this complication in the diabetic patients. The purpose of this study was to evaluate the prevalence of early neuropathic complication in patients with newly diagnosed type 1 and type 2 diabetes. METHODS: Nerve conduction studies (median, ulnar, posterior tibial, peroneal, and sural nerves) were performed for 49 type 1 (27 males, mean 14.1+/-7.5 years) and 40 type 2 (27 males, 42.0+/-14.1 years) diabetic patients at onset of diabetes. Children with age at onset under 4 years and adults over 55 years were excluded to eliminate the aging effect and the influence of obstructive arteriosclerosis. Neuropathy was defined as abnormal nerve conduction findings in two or more nerves including the sural nerve. RESULTS: Mean HbA1c level was 12.6+/-3.3% for type 1 and 10.5+/-2.9% for type 2 diabetes. The prevalence of neuropathy was 12.2% for type 1, and 35.0% for type 2 diabetes, respectively. There were significant trends in the prevalence of neuropathy with increasing age (p<0.05). The effect of the mean level of glycosylated hemoglobin on the prevalence of polyneuropathy at onset of diabetes was borderline (p=0.0532). Neither sex of the patients nor the type of diabetes affected the neurophysiologic abnormalities at the diagnosis. CONCLUSIONS: Even in a population with diabetes at the diagnosis, the prevalence of subclinical neuropathy was not low. Neuropathy has been significantly associated with increasing age indicating the possibility of longer duration of undetected diabetes among them, especially in type 2 diabetes.

Removal of blunt esophageal foreign bodies using Foley catheter under a fluoroscopic guidance is a well-recognized procedure. However, since this procedure is rather cumbersome and uncomfortable to the patient, the authors tried to find an easier and more convenient modified technique. For 10 patients with esophageal foreign body, we tried the method to the patients who is lying in the right lateral decubitus position and 3 assistants hold head. arms, trunk and legs of the patients without tilting the table and without using immobilizer. Foley catheter is inserted through nostril, nasal cavity and pharynx to esophagus. In order to identify the Foley catheter in esophagus, 0.025 inch short wire was inserted in the Foley catheter. The balloon of a Foley catheter was inflated by 10cc of air, and the syringe was kept attached to the Foley catheter during the procedure. After passage of the foreign body through the upper esophageal sphincter, the balloon was deflated immediately and the foreign body was removed through the mouth. We successfully removed in removing all the blunt esophageal foreign body with ease. This modified method is also fast, safe and efficient.

Photodynamic therapy(PDT) is a treatment modality by highly reactive oxygen intermediates generated through the interaction of light with a photosensiziter. It has been shown to be an effective treatment for various cutaneous and noncutaneous malignancies. It is efficient for the curative and palliative treatment of epithelial skin tumor in situ or early invasive lesions. In effect, it is a useful alternative treatment for the lesions located on anatomically difficult areas or the large-sized lesions. We treated a case of Bowen's disease arising on the plantar area and 3rd and 4th toewebs of left forefoot in a 61-year-old man with PDT using the hematoporphyrin derivative, porfirmer sodium(Photofrin, Russia) as a photosensitizer and gold vapor laser as a visible light source. The outcome showed partial clinical improvement after about 2 months' follow-up.

PURPOSE: To report a case of Merkel cell carcinoma on the left upper eyelid without metastasis and its immunohistochemical features. The carcinoma was successfully treated with excisional surgery and prophylactic radiation therapy. CASE SUMMARY: A 76-year-old woman presented to the hospital complaining of a 0.6 x 0.9-cm-sized painless and purplish-red colored mass that had grown rapidly on her left upper eyelid margin over the previous two months. An excisional biopsy was performed. On immunohistochemical examination of the lesion, the tumor cells expressed immunoreactivity for synaptophysin and were negative for LAC and cytokeratin, confirming the diagnosis of Merkel cell carcinoma. Additional surgery was performed because the surgical margins were positive. No other primary or metastatic lesions were found. The patient was treated with local prophylactic irradiation and remained disease-free at her 10-month follow-up visit.
