In children, snapping knee syndrome and joint pain with the loss of physiological hyperextension strongly suggests a diagnosis of a torn discoid meniscus. We performed arthroscopic meniscectomy to treat torn discoid lateral meniscus on 19 knees and open meniscectomy on 9 knees of 26 children(average age: 10.9 yrs) from September, 1983 to October, 1993 at Guro hospital. According to Ikeuchi's grading system', excellent results were obtained in 14, good in 11, fair in 2 knees and poor in 1 knee which was associated with osteochondritis dissecans. The knees treated by partial meniscectomy showed less Fairbank's radiologic changes than those by total meniscectomy during the average follow-up 4.2 years(minimum 1 year, maximum 7 year 11 months).

OBJECTIVE: The purpose of this study was to evaluated the effects of alcohol on neurocognitive function, psychomotor performance and subjective response in healthy Korean adults with different ALDH2 genotypes. METHOD: A total of 24 males, half with active ALDH2*1/2*1 and the other with inactive ALDH2*1/2*1, was selected through genotyping using restriction fragment length polymorphism. In a double-blind, placebo-controlled cross-over design, each subject consumed 0.5g/kg dose of alcohol, given as a mixture of 40% vodka and orange juice, and placebo(orange juice) on two separate occasions on an average of weekly intervals. The blood alcohol concentrations(BACs) were measured using a breath analyzer at baseline and at 30, 60 minutes after drinking. P300s were measured at baseline and at 30 minutes after alcohol and placebo intake. Vital signs and psychomotor performance[Critical Flicker Fusion Threshold(CFFT), Choice Reaction Time(CRT), Digit Symbol Substitution(DSS)] were measured at baseline and at 60 minutes after alcohol and placebo intake. Subjective responses were measured at the end of the study. The statistical analysis focused on whether there were any differences between groups with different ALDH2 genotypes. RESULTS: The major results are as follows. 1) BACs in inactive group were overall equivalent to those in the active group. Only in terms of time, BACs were significantly higher overall at 30 minutes than at 60 minutes after alcohol intake. 2) Pulse rates were significantly increased after alcohol intake compared with placebo, and the increase was greater in the inactive than in the active group. 3) P300 latencies in leads Fz(frontal), Cz(cental) and Pz(parietal) were significantly increased after alcohol intake compared to placebo, and the increase was greater in the inactive than in the active group. P300 amplitudes in leads Cz and Pz were significantly decreased overall after alcohol intake compared to placebo. 4) Compared with placebo, alcohol produced significant effect on the psychomotor performance : impairment in the inactive group, improvement in the active group. 5) Compared with placebo, alcohol significantly induced a negative or an intense effect on the subjective responses in the inactive group, but little negative and even a somewhat positive effect in the active group. CONCLUSIONS: These results suggest that ALDH isozyme variance might be an important factor to determine the effects of acute dose of alcohol on the various psychobehavioural functions and also to determine the alcohol use pattern and to predict the future development of alcohol overuse and/or abuse.

Chondroblastoma is a rare benign cartilaginous neoplasm that accounts for 1% of bone tumors and is common in the epiphysis of the long bones. The condition is rarely found in the talus bone (4% of cases). This paper reports a 15-year-old male patient treated for a talus bone lesion discovered incidentally on imaging. Excisional biopsy, curettage, and an autobone and allobone graft were performed, with good results.

Infertility, defined as 1 year of unprotected coitus without conception, affects approximately 10 to 15% for couples of reproductive age. Approximately 35% of these cases are attributable to male factor infertility. A major cause of male infertility is chromosome abnormality, such as 47 chromosomes with an XXY karyotype. Early surveys of infertile males showed that the incidence of major chromosome abnormality in infertile males in azoospermic patients. When patients are treated for male infertility, a chromosome analysis including a search for abnormality at the DNA level, should be performed. We have experienced a case of autosomal reciprocal translocation in azoospermic patient. So we report this case with a brief review of literatures.

We performed surgical treatment in 18 cases of torsion of the spermatic cord during the past four years. Patient age ranged from 2 to 54 years old : 13 cases were 16 or less. Torsion involved the left side in 11 cases. Surgical detorsion was performed in 10 cases, but in the other 8 cases orchiectomy was unavoidable. Of 8 cases treated with orchiectomy, the diagnosis was delayed in 7 cases due to mistaken diagnosis, primarily epididymitis by doctors in local clinics and general hospitals. The time of delay in the orchiectomy group ranged from 54 hours to 2 weeks with the average of 6.28 days. For one case, the visit to our hospital was too late. In 10 cases treated with surgical detorsion, all of the patients visited our hospital within 48 hours. Improvement of the testis salvage rate requires that adolescents, their families and teachers should learn to recognize this disease, and particularly doctors of other departments should recognize it as acute scrotum.

Insulinoma is a rare tumor, occurring more often in women and in the older age range. Eighty percent of patients have a single benign tumor, usually 2 cm in diameter, located with about equal frequency in body, head or tail of pancreas and amenable to surgical cure. About 10% have multiple tumors. The remaining 10% of patients have metastatic malignant insulinoma. The symptom of insulinoma is characterized by the periodic attack of hypoglycemia of blood sugar level below 50mg%, by fasting or exertion, and rapid relief of symptom by oral or intravenous administration of glucose. Symptom often lead to misdiagnosis as a neurologic or psychiatric disorder. A case described by authors was 44-year old female with the chief complaints of the loss of consciousness, epileptic seizure although she has been treated by anticonvulsants. Serum blood sugar and insulin level during fasting suggested insulinoma but abdominal computed tomography shows no definitive mass in pancreas. Celiac angiography revealed insulinoma. She transferred to the department of General Surgery and was performed enucleation. Microscopic findings shows the islet cell tumor of pancreas. A brief review of the literature was made.

Hydroa vacciniforme is a very rare photosensitivity disorder. The primary skin lesion is a vesicle or bulla which then heals with vacciniform scarring. We report a case of hydroa vacciniforme recurred after 3 years period of quiescence in a 20 year-old man who had had history of the disease from the age of two. The duplication of the natural lesion, clinically and histologically, was successfully made by artificial UV-A irradiation on the patient's back.
