This study was undertaken to evaluate the status of human paragonimiasis in Kang Hwa Gun, Kyunggi Do, Korea from March 1973 to October 1975 by the use of intradermal screening test with Veronal buffered saline antigen. A total number of 7,352 (male 3,936; female 3,4l6) consisting of 3,447 primary school children, 2,689 middle school students, l,008 high school students of 9 Myuns out of 13 Myuns of this County and 208 residents of all age group in Kilgeong-Ri, Yangdo Myun were examined by the intradermal test with Paragonimus antigen. In order to detect Paragonimus egg, the sputum and the stool examinations were undertaken on the residents in Kilgeong-Ri. The infestation rate of crayfish with Paragonimus metacercaria was also examined in Konneung and Jeongha village in Kilgeong-Ri. The following results were obtained in this survey: As a whole, 16.6 per cent of the examiners showed positive reaction with sexual difference of 16.1% in male and 14.8 per cent in female. In age groups, the highest positive rate showed in middle school age group (17.1 per cent) than primary school (14.0 per cent) and high school age group (11.4 per cent). In regional differences of positive rates, the highest rate (28.4 per cent) showed at Yangdo Myun followed by Kilsang Myun (27.0 per cent), Hwado Myun (25.0 per cent), and Naega Myun(20.8 per cent). In the result of 208 residents Kilgeong-Ri, the positive of 36.1 per cent in male and 20.2 per cent in female. The highest positive rate showed in 10 to 19 age group (41.5 per cent). Among the residents in Kilgeong-Ri, Paragonimus eggs were detected in 11 residents by the sputum and the stool examinations. The infestation rate of crayfsh with Paragonimus metacercariae was 100 per cent (41 out of 41 crayfishes) in Konneung village, and 84.6 per cent (9 out of 13 crayfishes) in Jeongha village, Kilgeong-Ri The fluctuation of the infection rate of crayfish with Paragonimus metacercariae was decreased in Konneung village in 2 years after the treatment with Bilevon against 10 paragonimiasis patients.

Malignant transformation of mature cystic teratoma is a rare complication. Most com-mon malignant transformation of mature cystic teratoma is squamous cell carcinoma, which represents about 75 to 80% followed by adenocarcinoma in 6 to 7%. It is generally consi-dered that prognosis is extremely poor in case of adenocarcinoma associated with cystic te-ratoma. In this paper, we describe an adenocarcinoma arising from a mature cystic teratoma of left ovary in 47 year old woman. Left ovary was measured 18x15x7cm, 1,295gm in size. Uterus and right ovary were normal appearance. Left ovarian cyst was adhered to omentum and peritoneum. But neither rupture of cyst nor ascites were found at laparotomy. A brief review of concerned literatures was presented.

As the world is facing an infectious disease pandemic caused by coronavirus disease 2019 (COVID-19), medical institutions are experiencing significant financial losses. we attempted to estimate such financial losses through a survey of clinics that reported temporary closure due to COVID-19 to the Korean Medical Association. As a result, the data of 56 clinics were obtained. The average closure period was 6.7 days, and the overall number of related health insurance claims and loss of sales reached 13,408,000 Korean won (KRW) and 20,911,000 KRW, respectively, while daily losses reached 1,343,000 and 2,202,000 KRW, respectively. In addition, the monthly average health insurance claims and sales were compared to those of the same month of the previous year. In January, they slightly increased by 4.4% and 7.8%, respectively, whereas in February, they slightly decreased by 10.2% and 12.4%, respectively. In March, they significantly decreased by 46.8% and 49.8%, respectively, as COVID-19 was at its peak. Considering the financial losses of clinics that played a pivotal role in quarantine at the forefront of infectious diseases, the government should prepare a reasonable compensation plan for such losses.

Systemic lupus erythematosus (SLE) which is thought to be autoimmune in nature affects multiple organs and produces a diversity of signs and symptoms. However, cardiovascular manifestations of SLE are manifested more frequently by autopsy. Recently, with the prolonged survival and improvement of diagnostic methods in SLE including echocardiography, the morbidity and mortality associated with cardiovascular manifestations of SLE became more apparent and increased. Simultaneous involvement of the pulmonary artery and the myopericardium in SLE is known to be rare. Pulmonary hypertension is known to be associated with poor prognosis. We report a 27 year-old female patient of SLE with pulmonary hypertension, pericarditis and left ventricular systolic dysfunction.

An aneurysm in the upper extremity is rarer than in the lower extremity, and a traumatic false aneurysm is very rare. We encountered two patients with a traumatic false aneurysm in the upper extremity. The first case developed from a posterior interosseous artery injury after an internal fixation using a plate and circumferential wiring for a comminuted fracture of the proximal shaft of radius associated with a dislocation of the left elbow joint. This patient was managed by excision of the false aneurysm, and ligation of the artery. The second case developed from a radial artery catheterization on the left wrist. This was managed by excision of the false aneurysm and an end-to-end anastomosis and resulted in the disappearance of the false aneurysm and a good vascular patency. We report two rare cases of traumatic false aneurysm in the upper extremity and a review of the literature.

Little is known about the treatment-seeking behaviors of acne patients, especially Asian acne patients. This study was performed to obtain detailed information about the treatment-seeking behaviors in Korean acne patients. Patients who visited the dermatology departments at 17 university hospitals completed a self-administered questionnaire. Most patients obtained information about acne from doctors or the Internet. The most important criteria for selecting a treatment method or choosing a particular clinic were effectiveness and accessibility. Patients used traditional medicine, visited beauty clinics, drank more water, and used over-the-counter topical agents more frequently than they sought doctors during the worsening period. The degree of satisfaction in treatment was found to depend on the total cost of treatment, number of places visited, site affected by acne, and emotional stress. Those who had experienced a side effect tended to have been treated for longer, to have paid more for treatment, and to have an associated skin disease. Treatments prescribed by dermatology clinics had the lowest aggravating rate, although improvement rates for family medicine clinics were also fairly high. This is the first study to investigate in detail the demographic features and characteristics of the treatmentseeking behaviors of acne patients in Asia.
