In order to discover difference that may exist in quantity of medical care services, length of stay and hospital changes between insured and non-insured patients, records for primary Cesarean section patients discharged between July 1978 and June 1980 from a university hospital were examined. In addition, Cesarean section rates among the total deliveries for a two-year period between the groups were studied. The results showed that volume of services was greater and length of stay was longer among the insured, however, charges were higher among the non-insured. Cesarean section rates were statistically significantly different between insured and non-insured patients for every age group except the group of 35 or more.

Alternaria cassiae Jurair & Khan was recorded on seeds of sickle senna(Cassia tora L.). Seed infection ranged from 25~45% in two samples. Developing roots and shoots turn brown and died in case of severe infection. Detailed descriptions were given on the habit characters of the fungus and on the morphology of conidiophores and condia. This is the first report of A. cassiae on seeds of Cassia.

Diphyllobothrium latum infection in humans is not common in Republic of Korea. We report a case of fish tapeworm infection in a 10-year-old boy after ingestion of raw perch about 8 months ago. The patient complained of recurrent abdominal pain and watery diarrhea. A tapeworm, 85 cm in length, without scolex and neck, was spontaneously discharged in the feces of the patient. The patient was treated with 15-mg/kg single dose praziquantel, and follow-up stool examination was negative after one month. There was no evidence of relapse during the next six months.

The Dandy-Wlaker syndrome is a developmental disoeder characterized by cystic dilatation of the fourth ventricle and agenesis or hypoplasia of the cerebellar vermis and is usually associated with hydrocephalus. This syndrome is also associated with intracranial malformations such as agenesis of corpus callosum, and extracranial malformations such as facial anormalies (cleft palate, cleft lip, and ocular anomalies), polycystic kidney, and cardiac anormalies. Reported associated ophthalmic anomalies are microphthalmos, coloboma, and congenital cataract.We experienced a case of infantile esotropia in abnormal insertion and direction of lateral rectus muscle as a variant of the Dandy-Walker syndrome accompanied by cleft palate and cleft lip in a 19-month-old male infant. Subsequent treatment of the 30delta esodeviation and left inferior oblique muscle overaction, including resection of the lateral rectus muscle in both eyes and the myectomy of the inferior oblique muscle in the left eye, yielded satisfactory results, so we report this case, with a review of the pertinent literature, as the first case of Dandy-Walker syndrome associated with esotropia with abnormal course of lateral rectus muscle in Korea.

Leiomyomas of vagina and vulva are rare solid tumors, but most common mesenchymal tumors in adult woman. Most of the reported cases have been benign. The tumors were firm, well-defined submucosal masses in a majority of patients. We experienced two cases of vulvar and vaginal leiomyoma, thus it is presented with a brief review of the cases and its literatures.

In this study, the number of physicians presently living in Korea thoroughly estimated by several means and, on this bases, their productivity and level of supply were estimated. The results were as follows : First, the number of physicians who did not notify the Korea Medical Association in May 1987 were 10,110, including 4,093 emigrant physicians(40.5%), 861 military medical officers, 745 public health doctors, and 107 decreased physicians. A total of 1,330 physicians could not be identified by any effort. Second, among the 34,897 registered physicians as of May 1987, 29,933(85.8%) were residing in Korea, 4,115 physicians(11.8%) had emigrated to other countries, and 849 physicians(2.4%) were decreased. Practicing physicians defined as those in Korea who were not retired, serving in the military, or completing residencies or internships, comprised 78.6%(27,414 physicians) of the total number of registered physicians. Third, it is estimated that in the year 2000 the number of registered physicians, physicians residing in Korea, and practicing physician will be 75,040, 64,038 and 57,655, respectively and these are increases of 115.0%, 113,9%, and 110.3%, respectively, compared to 1987. Fourth, the population physician ratio will be 759 to one physician in the year 2000. Fifth, the productivity of physicians, as calculated by relative values defining the productivity of 35 to 44 year-old male physicians as 10, will increase 110.7% in the year 2000 compare to that of 1987, and this increment is almost the same level as that of physicians supply. From the results of the present analysis of physicians manpower and supply projection, it can be recognized that the development of a regular notification system is necessary in order to identify precisely the number of physicians. Also a policy a physician supply is essential in order to adjust in advance the number of physicians, otherwise there will be surplus to the medical demand.

OBJECTIVES: This study aims to analyze the association between the severity of sleep apnea, sleep and mood related scales, and activity during sleep in obstructive sleep apnea syndrome (OSAS) patients. METHODS: One hundred seventy six drug-free male patients confirmed as OSAS (average age=43+/-11 years) were selected through nocturnal polysomnography (NPSG). OSAS was diagnosed with apnea-hypopnea index (AHI) >5, mean AHI was 39.6+/-26.0. Sleep related scales were Stanford Sleepiness Scale (SSS), Epworth Sleepiness Scale (ESS), Pittsburg Sleep Quality Index (PSQI) and Morningness-Eveningness Scale (MES). Mood related scales were Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), State-Trait Anxiety Inventory (STAI) I, II and Profile of Mood States (POMS). NPSG was performed overnight with both wrist actigraphy (WATG). Parameters produced from WATG were total activity score, mean activity score and fragmentation index. We analyzed the correlation between each scale, AHI scored from NPSG and activity score analyzed from WATG. RESULTS: ESS showed significant positive correlation with PSQI, BDI, BAI and STAI I, II, respectively (p<0.01). SSS showed significant positive correlation with PSQI and BAI (p<0.05, p<0.01). BAI showed significant positive correlation with total activity score, mean activity score and fragmentation index (p<0.05, p<0.01, p<0.05). Total activity score showed significant positive correlation with ESS and BAI, respectively (p<0.05). Fragmentation index showed significant positive correlation with ESS, PSQI and BAI (p<0.05, p<0.01, p<0.05). AHI, indicator of sleep apnea is showed no significant correlation with each sleep and mood related scale. CONCLUSION: The degree of daytime sleepiness tends to be associated with night sleep satisfaction, depression and anxiety, and the activity during sleep rather than the severity of sleep apnea.
