This study was designed to investigate whether recruitment of physicians and dentists has been restricted to a social network, such as familial or kinship groups. The data was collected through a self-administered questionnaire survey distributed to a sampling of general physicians, specialists (internists, surgeons, other specialists), and dentists in August 1990. The major findings are as follows: 1) Total number of respondents was 405; of these, general physicians made up 48.9%, internists 10.4%, surgeons 15.8%, other specialists 4.9%, and dentists 20.0%. 2) 38.5% of the respondents had physicians or dentists in their immediate family or were related in some way to one. Those from urban areas, whose parents were highly educated, and whose father was a professional had more physicians or dentists in their family or kinship. 3) Parents of 7.1% of the respondents, brothers or sisters of 10.1%, grand parents of 1.7%, uncles or aunts of 7.9%, and cousins of 22.0% were physicians or dentists. 4) The majority of physicians or dentists in familial or kinship network specialized in surgery, 32.3%, followed by internal medicine ; current worksites were noted as clinics by 30.8%, followed by general hospital, university hospital, and so on. The respondent's major discipline tended to follow familial or kinship example. Consequently, it was concluded that physicians and dentists have been recruited within restricted familial or kinship network.

Angiogenesis, the induction of new capillaries and venules, is associated with tumor growth. This study was designed to determine whether cervical carcinomas are angiogenic, and to investigate whether tumor angiogenesis can serve as a prognostic factor in cervical carcinoma. Surgical specimens of 47 cervical carcinomas were immunohistochemically stained specifically for endothelial cells with factor VIII-related antigen to identify all vessels. Microvessels were counted from photographs of 200x microscopic fields. In addition, thirty-seven cases were studied by immunohistochemical means using the monoclonal antibodies for PCNA and for Ki-67 to determine tumor cell proliferation rates in cervical carcinomas. The microvessel count(MVC), the PCNA labelling index, and the Ki-67 index were calculated and compared with known prognostic factors and disease free survival rates in cervical carcinomas. A wide range in the MVC count(range 12-100 mean=38.2+/-19.2), the PCNA labeling index(8-69% mean=33.6+/-15.2%), and in the extent of Ki-67 staining(0-43% mean=10.3+/-10.5%) was observed, indicating considerable variation of tumor angiogenic activity and tumor growth rates. This study showed statistically significant correlations in disease free survival rates with both lymph node status and the microvessel count. However, there was no significant difference in disease free survival rates between tumor stage, age, the PCNA labelling index, and the Ki-67 index.

Internal hernia is an unusual cause of the intestinal obstruction. The advances of CT make the diagnosis more easier than in the past. We report one case of internal hernia with herniation of the ileum into the lesser omenturn. The diagnosis could be made when abdominal radiographs showed fixed clustering of the small bowel loops in upper abdomen medial to the stomach. CT and ultrasound showed characteristic interposition of the ileum between the left hepatic lobe and the stomach.

The etiology of spontaneous hemarthrosis of the knee joint in elderly pattents is still unknown. This report discusses seven spontaneous hernarthroses, three that were managed witla conservative measures such as aspiration, rest and knee immobilization because of poor general condition and four in which arthroscopic evaluation and treatment were performed. These patients were elderly indi.viduals without an obvious history of trauma. The roentgenograms of each involved knee demonstrated degenerative osteoarthritic changes of knee joint. Arthroscopic examination revealed denuded articular cartilage and subchondral bone exposure in four operative cases and degenerative meniscal tear in one case of four. These patients underwent mthroscopic debridement and did not experience recurrenees of the hemarthrosis. We think that the origin of the bleeding was most likely from the subchondral cancellous bone which was exposed due to degenerative change of the knee joint and the senile changes of the vessels around the knee joint with aging process may contribute the spontaneous bleeding into the knee joints.

Intravascular papillary endothelial hyperplasia is a benign solitary turnor that may be histologically misdiagnosed as angiosarcoma. We present herein a case of intravascular papillary endothelial hyperplasia occuring in 40-year-old female who hsd a slowly growing tumor on the tongue for 3 years. the histopathologic findings revealed. papillary endothelial hyperplasia in blood vessel accompanied with thrombi.

Primary renal lymphoma is a rare tumor of the kidney that typically presents with bilateral nodular enlargement in the absence of extrarenal masses. We describe MR findings of a case of primary renal lymphoma along with ultrasound and CT findings. MR imaging demonstrated globular enlargement of both kidneys with multilobulated contour and multiple masses which had isosignal intensity on T1WI and low signal intensity on T2WI. The masses enhanced slightly on dynamic contrast enhanced scan.

The purpose of this study is to examine the factors influencing the allergic rhinitis patients' satisfaction with laser surgery. The data were collected by telephone interviews with 211 patients who visited E university hospital. The statistical methods used for the analysis were factor analysis, reliability test, and hierarchical multiple regression. We find that satisfaction level is a function of not only the surgery outcome but also the socio-psychological experience during treatment. With the improvement in nasal allergic condition, patients were more likely to be satisfied with medical services. And patients who had positive experience with physicians and facilities reported higher satisfaction level. While the surgery outcome explained 68% of the variation of satisfaction level, socio-psychological experience explained 23% of it. This result clearly shows that physicians need to pay attention to the socio-psychological aspect as well as the technical aspect of medical services.

We reviewed two cases of keratosis punctata palmaris et plantaris(KPP) and the scanning electron microscopic findings(SEM). The skin lesions of KPP are multiple, hyperkeratotic on the palms and soles with central pitting. There was no subjective symptoms. The histologic findigs revea,l marked hyperkeratosis, hypergranulosis, and acanthosis with depression of the underlying malpighian layers. The SEM findings reveal one hyperkeratoic plug on punctate lesion(case I ) and three hyperkeratotic plugs on depression of the malpighian layer(case ll ).

For the purpose of epidemiologic study, the patients who visited Severance Hospital Behcet's Syndrome Specialty Clinic were grouped by Shimizu classification into the complete, incomplete, suspected types and evaluated. The results of the evaluation with respect to personal characteristics, geographic distribution, socioeconomic characteristics, family history, and clinical characteristics are as follows. 1. The incidence among the subgroups was incomplete type(46.3%), suspected type(36.7%), complete type(17.0%) and the male to female ratio was 0.60: 1, and the average age of onset was 29.1. years for males and 27.6 years for females. 2. The occupational distribution among males included office workers, 31.5%; drivers, 10.6% and among females was office workers, 6.7%; teachers, 3. 7 %; unemployed, 81.7%. 3. Among the presumed aggrevating factors affecting oral cavity, recurrent tonsillitis(20.8%) was most common, and premenstrual exacervation(12.8%) was most common. 4. The most common initial major manifestation was oral ulcer(80.6%), and the longest duration of major manifestations was oral ulcer(average 6.4 years), and the most frequent relapse of major manifestations was oral ulcer(average 14.6 times/year). 5. The average duration between the appearance of the first and second major manifestations was 5.2 years for complete type, 6.3 years for incomplete type, and 6.6 years for suspected type. 6. Combinations of major manifestations most commonly included oral ulcer, genital ulcers and skin lesions(65.3%) for incomplete type, and oral ulcer, skin lesion(54.8%) for suspected type.
