Nevus comedonicus is a rare skin abnormality characterized by a unilateral and usually linear distribution of groups of comedones, Histologically, local epidermal invagination and keratin material plugging in invaginated pouch and immatured hair follicles on lower part of the pouch were seen. Two cases are reported at first in the Korean literature. Case 1: A 24 year old man has had black colored comedolike skin lesions on left cheek with 16 years duration without any subjective symptoms. Case 2: A 19 year old girl has had multiple comedolike lesions on right buttock with 2 years duration, acompanied by recurrent suppuration and moderate itching. Our 2 cases, all are typical Nevus Comedonicus Unilateralis case in clinically and histopathologically. Treatment with local application of steroid cream and dermoabrasion resulted good effect, but essentially there is no need to treat untill complication deveoped.

A 53-year-old man had skin-colored linear serpiginous plaque within brownish patch on his left thigh for one year. He habitually drank natural spring water for 3 years. We diagnosed this case as sparganosis infiltrated within dermis by histologic and parasitologic diagnosis. The skin lesion mimicked the cutaneous larva migrans by showing dermal migration of sparganum to pro-duce itchy linear serpiginous plaque. We report an interesting case of sparganosis mimicking cutaneous larva migrans.

Primary malignant melanornn of the vagina is rare, with only about 130 reported cases worldwide. They presumably arise from melanocytes that are present in the vagina in 3% of normal wornen. Vaginal melanoma accounts for less than 1% of melanomas and less than 3% of primary malignant tumors of the vagina. Most of patients complain vaginal bleeding, vaginal discharge, foreign body sensation in order. The best treatment of vaginal melanoma rernains eni.gmatic, Many authors indicate that radical surgery may be the pcferred approach and the number of reported cases treated with radical surgery is increasing. But other author comment that no significant change in survival is apparent with radical surgery. Overall prognosis is poor as most patients have deeply penetrating lesions at the time of diagnosis. Recently, not only the effort to increase the survival rate but the quality of life including sexual function after treatment is becoming an important issue about treatment ot cancer patients. We experienced a case of primary malignant melanoma of the vagina treated with radical surgery and restored the sexual function by vulvovaginal reconstruction using gracilis myocutaneous flap. So we report this case with brief literature review.

During a 12-month period high-resolution, real-time ultrasonography (US) with graded compression was performed on 268 consecutive patients with clinically suspected acute appendicitis and its complication. US visualization of a fluid-filled, non-compressed appendix or a decompressed, thick-walled appendix was the primary criterion for a diagnosis of acute appendicitis. The sonographic findings were correlated with surgical-pathologic outcome in 92 cases and with the findings of clinical follow-up in the remainder. US was found to be accurate in the diagnosis of acute appendicitis and its complication with a sensitivity of 93.3%, a specificity of 98.9%, and an accuracy of 97%. The predictive value of a positive test was 97.7%; that of a negative test was 96.7%. There were two false-positive examination in patients with a thick-walled appendix or periapperdiceal abscess, which were surgically confirmed as appendiceal adenocarcinoma and perforated cecal diverticulitis respectively. There were six false-negative examination in patients with a sonographically no-visible appendix, which were confirmed surgically as acute appendicitis(n=5) and perforated appendicitis(n=1). Our results show that high-resolution, real-time US is an accureate imaging modality in the diagnosis of acute appendicitis and the evaluation of its complication.

PURPOSE: Kindling refers to a process whereby repeated applications of an initially subconvulsive electrical or chemical stimulus to animals lead to persistent epileptogenic in generalized seizures. Metabotropic glutamate receptors (mGluRs) have been shown to be involved in many brain functions. Widespread distribution of the mGluRs suggests glutamate may be the primary modulator of G-protein coupled signal transduction in the central nervous system. To investigate the role of mGluRs in kindling, we studied the changes of mRNA gene expressions of mGluR1 and 5 on the hippocampus, amygdala, and basal ganglia in PTZ-induced kindled rats. METHODS: Male Wistar rats (n=6-4) were kindled by repeated administration, 5 times a week, by a subconvulsant dose of PTZ (35 mg/kg). After completion of kindling, the brains were analysed for mRNA gene expression of mGluR1 and 5 using reverse transcripted polymerase chain reaction (RT-PCR). RESULTS: The kindling score was significantly increased after 8 injections and the definitive kindling score (more than 4 point) was obtained after 10 injections. mRNA gene expressions of mGluR1 in hippocampus, amygdala, and basal ganglia were increased by 180.1+/-4.4%, 130.2+/-6.1%, 148.6+/-1.4% compared to controls (p<0.05), but those of mGluR5 were not significantly increased. CONCLUSIONS: Although the mRNA gene expression of mGluR5 did not show any marked changes in kindled rat brain, that of mGluR1 showed significant increase in hippocampus and amygdala. From these results, high density of mGluR1 may suggests glutamatergic systems plays a role in PTZ-induced kindling. But our results would not exclude the possibility that changes of mRNA gene expressions of mGluR1 and 5 are due to repeated seizure activity alone.

Peptic ulcer disease in children presents an interesting and sometimes difficult problem to the clinicians. Since the incidence is quite small in children, only small collected series have been reported in the literature. With the improvement of diagnostic aids (particularly radiologic equipments and greater attention paid by clinicians, peptic ulcers have been detected with increasing frequency. However, there is a paucity of information available concerning this disease in infancy and childhood in Korea. The symptoms and signs of peptic ulcer disease in childhood are obscure and have many differences from those of tihe adult, which too often go unrecogntzed until complications set in. The authors made on clinical observation on 14 patients with peptic ulcer under the age of 15 years, who had been admitted to the department of pediatrics of National Medical Center from Aug, 1972 to July 1978. The age, sex and seasonal incidences, type and location of ulcer, symptom curation, clinical and laboratory findings, complications and prognosis were analyzed and the data are summerized as follows. 1) The incidence of peptic ulcer in childhood was 0.33% of a total 4221 admissions, and the average number of patients of peptic ulcer per year was 2.3. 2) Among 14 patients, 9 cases (68%) were between 12 and 15 years of age, 4 patients (28%) between 7 and 11, and the majority (93%) were between the ages of 7 and 15. The youngest patients wea 4 year old male. 3) Sex incidence showed that males predominated in a proportion of 13:1. 4) Seasonal incidence was relatively high (inspring) (28.6%) and autumn (42.9%). 5) Three cases (21.5%) had gastric ulcer and 11 cases (78.5%) had duodenal (ulcer, 12 cases were diagnosed as primary type and 2 cases were) thought to be secondary type due to steroid therapy. 6) Duration of symptoms were variable, with the range between 1 week and 3 years. 7) The majority have abdominal pain (100%), vomiting (85.6%) and epigstric tenderness (71.4%), Other symptoms and signs were anemia (42.9%), indigestion (38.5%), melena (38.5%), epigastric pain (28.6%), general weakness (21.5%), weight loss (14.3%) and abdominal rigidity (14.3%). 8) Gastric analysis was performed in 5 patients, 2 of these patients had slight hyperchlorhydria, but 3 cases showed normal results. 9) Complications were found in 4 patients (28.6%). These were perforation (2 cases, 14.3%) and obstruction (2 cases 14.3%). Postoperative condition during hospitalization was excellent. 10) Among the chronic primary ulcer patients (12 cases), ulcer symptoms disappeared in 10 cases with medical treatment such as antacids, tranquilizers and other conservative treatments and within one month after treatments were discharged with improvement.

The clinical study was made on 38 cases of the congenital megacolon who had been admitted to Dept. of Pediatrics and General surgery, National Medical Center from Jan., 1869 to Dec., 1977 We obtained the following results. 1. The sex ratio was 4.4 : 1, of male preponderance. 2. The onset of symptoms was within 1 week after birth in majority of the cases. 3. All patients were delivered at fullterm and the familial occurrence was not observed. The associated anomalies were a case of mongolism with congenital heart disease and of congenital hypertrophic pyloric stenosis. 4. In about half of the cases, the definitive diagnosis was made before the age of 6months 5. The clinical symptomes were abdominal distension, constipation, vomiting, diarrhea, visible peristalsis and weight loss in order of frequency. 6. Meconium passage was spontaneous in 41.2% and after digital examination or enema in 58.8%. 7. The majority of the cases(79%) were so called short segment type. One male patient was proved to be total aganglionic colon. 8. The definitive operation was performed in 18 cases, in which 14 cases(77.7%) received Swenson's procedure. The early complications were wound infection, leakage, fistula, pelvic abscess and the late complications were stricture, intestinal obstruction, enterocolitis, fecal impaction, malnutrition in order of frequency. 9. The total mortality rate was 23.7% and the operation mortality was 16.7%. 10. The results of one stage operation was somewhat better than two stage operation. 11. The follow up results were good in 83.3% of operated cases.
