Sjogren's syndrome has been considered to be an autoimmune disease affecting various organs including salivary and lacrimal glands. It occurs most commonly in middle-aged women, and less than 20 cases with primary Sjogren's syndrome have been reported in children. An 11-yim-old boy presented with recurrent annular erythema on the face that had been present for 2 years. A schirmers test showed a positive result. ANA was detected at a dilution of 1:640. Anti-Ro/SSA and anti-La/SSB antibodies were also detected. On histological examination, lymphocytes were infiltrated in the periappendegeal areas as well as the papillary and reticular dernis. The skin findimg is uncommon in children, but has become a characteristic feature of childhood Sjogrens syndrome with anti-Ro and/or anti-La antibodies.

This study was performed to investigate the factors related to tooth wear. For this study, 78 patients with temporomandibular disorders and 76 dental students without any signs and symptoms of temporomandibular disorders were selected as the patients group and as the normal group, respectively. Preferred chewing side, Angle's classification, lateral guidance pattern, head and shoulder posture wee observed clinically. Electromyographic activity of anterior temporalis and masseter muscle were recorded with BioEMG and occlusal status were recorded with T-Scan . Wear facet area of each tooth was measured from working model of upper arch corresponding to the occlusal status from T-Scan, Wear facet area were measured with planimeter in mm2. Total area were divided into incisal, canine, posterior tooth area. Anterior wearfacet area was incisor area plus canine area, and unilateral area was anterior area plus posterior area. The data collected were analyzed by SAS statistical program and the results of this study were as follows: 1. There was no significant difference between the two groups in total werafacet area, and male subjects showed tendency to have larger area in the normal group but female subjects showed tendency vice versa. 2. There was no significant difference related to preferred chewing side and Angle's classification, however, some difference was observed by lateral guidance pattern. Anterior wear facet area in subjects of canine guidance was the largest in the three subgroups. 3. Subjects with head tilting to right side had larger posterior and total area, and subjects with higher shoulder in right side had larger canine and anterior area than any other subgrous. 4. Electromyographic activity of masseter muscle was more correlated with wear facet area than anterior temporalis muscle, and tooth contact number and force were significantly correlated with wear facet area, but the most important factor affecting tooth attrition was age.

Streptococcus anginosus is a member of Streptococcus milleri group, and is found in the oral mucosa, respiratory tract, and gastrointestinal tract as normal flora. It can develop into a disease in patients with deteriorating clinical condition or with clinical risk factors. A previously healthy 15-year-old boy was admitted due to fever, abdominal discomfort and vomiting which lasted for 7 days. He had a history of dental procedure 1 day before the development of fever. He was diagnosed with acute acalculous cholecystitis based on the clinical, laboratory, and imaging finding, and S. anginosus was isolated from the blood culture. The patient was successfully treated with antibiotic therapy.

PURPOSE: Instead of a chaotic non circadian environmental approach, continuing regular day-night rhythm in neonatal nurseries may benefit the development of preterm infants. The purpose of this study was to define the effects of cycled lighting on circadian rhythms of premature infants. METHODS: The experimental group included 15 preterm infants, and the control group, 15 premature infants in the NICU of a general hospital in Seoul. All infants were between 32 and 37 weeks' postconceptional age. The experimental group infants were provided with cycled lighting before discharge. The incubator or bassinet cover of the experimental group was off between 7 AM and 7 PM, and was covered between 7 PM and 7 AM. RESULTS: There were significant differences in the NNNS score (p=.039), and some significant differences in the sleep-activity pattern between the experimental group and the control group, but distinct differences in sleep-activity patterns between the two groups could not be defined. CONCLUSION: The results of this study suggest that cycled lighting can be helpful in the neurobehavioral development of preterm infants. By modifying the NICU environment to provide a more developmentally supportive milieu, nursing professionals can better meet the infants' physiologic and neurobehavioral needs.

Clinical observation was done in 18 cases of renal cell carcinoma, who has been admitted to Department of Urology, Kyung Hee University Hospital from January, 1978 to June, 1984. Results were as follows; 1. Among the 18 cases, male was 11 cases and female was 7 cases, and mean of age was 52.1 year (range : 39-67 year): 2. In 4 cases suspected renal vein or inferior vena cava involvement of tumor in angiography, venacavography was performed and revealed involvement of renal vein in 1 casts and vena cava in 2 Cases. 3. 8 of 9 cases with large tumor (over 10cm diameter) in angiography, tumor involvement of renal vein was found. So, venacavography should be done in case of large tumor (over 10cm diameter) in angiography. 4. In comparison between preoperative clinical stage and postoperative pathologic stage, 11 of 15 casts were same. 5. In 18 cases 2 cases were treated by simple nephrectomy and 16 cases by radical nephrectomy. Inferior vena cava thrombectomy was done in 3 cases 6. Adjuvant treatment (chemotherapy in 5 cases, irradiation in 2 cases) was done in 7 cases, their effectiveness were minimal.

Total 8,341 pregnant women who visited Obstetric Clinic Cheil General Hospital from Jaunary 1991 to July 1992 were screened for HBsAg. Sixty five women with positive HBsAg who delivered healthy babies during that period and their infants are included in the study. HBsAg, Anti-HBs, Anti-HBc, HBeAg and Anti-HBe were tested by radioimmunoassay and hepatitis B virus DNA were studied by polymerase chain reaction technique in both mothers' and babies serum. The results were as follow: 1) Among 8,341 pregnant women who were screened for HBsAg 374 were asymptomatic carriers(4.5%). 2) The newborn babies born to 65 mothers who were positive HBsAg showed HBsAg in 4.6%, HBeAg 75.0%, anti-HBc 98.4% and hepatitis B virus DNA in 26.2%. 3) It showed discordance of HBeAg/anti-HBe, with hepatitis B virus DNA in newborn infants. 4) Follow up study at 8~20 months showed HBeAg and hepatitis B virus DNA in 2 infants out of 20.

Subcutaneous emphysema is a complication of the pneumoperitoneum necessary to perform laparoscopy and will be seen more often as laparoscopic techniques are applied to a growing number of intraabdominal procedures. We report a case of subcutaneous emphysema and hypercarbia without pneumothorax or pneumomediastinum during laparoscopic cholecystectomy, which was treated by multiple puncture with 18G needle on emphysematous site. The suspected cause is inadvertent subcutaneous insufflation of carbon dioxide through the trocar sites by increased intra-abdominal pressure for the establishment of pneumoperitoneum. Immediate recognition, evaluation, and treatment of subcutaneous emphysema is necessary since this can be life-threatening complication.

The Sertoli-Leydig cell tumor is a gonadal tumor of sex-cord stromal type, similar to that seen in of the various phases of testicular development in the male. This tumor is exceedingly rare, accounting for only 0.1% to 0.5% of all primary ovarian neoplasms. It occurs predominantly in the second and third decades(mean age about 25 years), less than 10% after menopause. We investigated a case of poorly differentiated Sertoli-Leydig cell tumor of right ovary, occured in a 76-year-old woman. Grossly, the tumor measured 2, 100 gm in weight and 25 x 19 x 8 cm in dimensions. The outer surface was smooth and glistening without rupture of the capsule. Cut sections revealed a multilobulated brown solid mass with multiple cystic change. Microscopically, it showed the typical findings o a Sertoli-Leydig cell tumor. The characteristic feature is hemangiopericytoma paftem of sarcomatoid spindle cells. Therefore, we present it with a brief review of the literature.

Author reviewed the patients with temperature over 38.5 degress C for longer than two weeks and of undetermined etiology who were admitted and treated in Yonsei Medical Center during the period from Jan. 1974 to Aug. 1978. There have been 120 cases of prolonged fever in that period. The following results were obtained; 1. The children who were admitted with prolonged fever occupied 1.3% of total in-patients at the same period. 2. 16 cases were less than 1 year of age at admission and 64 were 1 to 6 years. So 2/3 of total cases were less than 6 years of age. The ratio of Male to Female was 1.6:1. 3. There Was no apparent difference in seasonal incidence. But from May to September slightly increased number was noted. 4. In 58 cases(48.3%), the fever persisted 2 to 3 weeks before admission and 27 cases lasted longer than a month. . Three patterns of fever were observed; intermittent type 75 cases(62.5%), daily spiking 32(26.7%) and constant 13(10.8%) 5. The final diagnoses as a cause of fever were as follows. Infections accounted for 81 cases(67.5%), malignancy 17(14.2%), collagen diseases 7(5.8%) and miscellaneous cause 1(0.8%). 14 cases(11.7%) remained undiagnosed at the cenclusion of their hospitalization. . Certain relationships between diagnosis and age were noted. Infection was the most common etiology in all age groups but 72.5% of these children were less than 6 years old. 71.4% of collagen diseases were older than 6 years. Malignancy had no age predilection. 6. Over 80% of all cases the diagnosis were made within a week and the fever disappeared in a week in 70% So most of them(75%) discharged within 2 weeks after admission. 7. Careful history suggested the final diagnosis in 84 cases(70%) and repeated physical examinations were helpful in 70 cases(58.3%) Abnormal findings in routine chest P-A were present in 47.5% Erythrocyte sedimentation rate was significantly increased in 26/34 cases(76.5%). 47 cases(39.2%) were anemic for age and all children with malignancy were anemic. Lumbar puncture, bone marrow aspiration, tissue biopsy and explo. Laparotomy were performed only in suspected cases. 8. Outcome on discharge were as follows; 90 cases(75.0%) were much improved, 21(17.5%) discharged without improvement and 9 cases(7.5%) expired.
