BACKGROUND: The peak flowmeter is very useful in monitoring of out-patients as well as those in emergency departments because of its convenience and simplicity with low cost. There have been many studies aimed at determining the accuracy and reproducibility of the peak flow meter in normal population. However, there is a paucity of reports regarding its accuracy in patients with chronic obstructive pulmonary disease(COPD) or asthma. The accuracy of the peak expiratory flow(PEF) measured with a mini-Wright peak flowmeter was assessed by a comparison with the results of a mass flow sensor. METHODS: The PEF measurements were performed in 108 patients aged 19-82 years presenting with either a chronic obstructive lung disease or asthma before and after inhaling salbutamol. The PEF measurements from the mini-Wright flowmeter were compared with those obtained by the calibrated mass flow sensor. RESULTS: The average of the readings taken by the mini-Wright meter were 37-39 l/min higher than those taken by the mass flow sensor. The average percentage error of the mini-Wright meter were higher, ranging less than 300 l/min. The mean of the differences between the values obtained using both instruments (the bias)±limits of agreement(±2 SD) were 37.1±90 l/min for the PEF(p<0.001). CONCLUSIONS: The mini-Wright peak flowmeter overestimated the flows in patients with COPD or asthma. It was also found that the accuracy of the mini-Wright peak flowmeter decreased in its mid to low range. The limits of agreement are wide and the difference between the two instruments is signigicant. Therefore, the measurements made between the two types of machines in patients with asthma or COPD cannot be used in terchangeably.

This study was conducted to investigate food and meal preference of workers (435 male and 212 female) in the Chonnam Yeosu industrial area. The results of the survey were analyzed by principal components analysis. The results were obtained as follows: 19.3% of the subjects were twenties, 28.3% were thirties, 28.8% were forties and 23.7% were fifties. Females liked rice rolled in dried laver, rice cakes, janchi-noodle and breads, on the other hand males liked thick beef soup, loach soup, an eel stew and soju. The young liked instant noodles, fried chicken, sweet and sour pork, pork cutlet, pizza, hamburger, ham, sausage and fruit beverage, on the other hand the old liked a fish pot stew, loach soup, eel stew, fish boiled in soy with spices, panfried fish, sea slug, ascidian, bunder, green laver and boiled burdock-lotus root in soy. Females who are young liked hamburger and sweet and sour pork whereas males who are young liked instant noodles, pork cutlet, ham, sausage and fruit beverage. Aged females liked fish boiled in soy with spices, panfried fish, bunder, green laver, boiled burdock-lotus root in soy whereas aged males liked a fish pot stew, loach soup, eel stew, sea mussel and oysters. Boiled rice was located within the middle irrespective of age and sex, but noodles, wheat flour meal, fast foods and fruits were situated at the young female side. Aged males liked soup and pot stew. Young males liked meats and eggs whereas fish and shellfish and kimch were located at the aged people side. Aged females liked sea weeds and most people disliked vegetables but females liked some vegetables irrespective of age. Processed foods, salted foods, and alcohol were generally disliked foods by subjects but males liked those foods. Soybean curd was liked more males than females, and teas, except coffee, was liked by males.

We report a case of recurrent herpes genitalis in a 5-year-old girl which was considered to result from childhood sexual abuse. The skin lesion was an eroded erythematous macule with overlying multiple vesicles on the labia majora. We detected Herpes simplex virus DNA by using the polymerase chain reaction (PCR) in a biopsy specimen from the vesicular lesion.

PURPOSE: recent studies have reported that the expression of Drg-1 is up-regulated by androgen. It has been suggested that Drg-1 gene be used as a molecular marker for prostate cancer therapies like PSA. To de termine the role of Drg-1 gene as a molecular marker during intermittent androgen deprivation(IAD) therapy, we investigated the expression of Drg-1 and compared it with PSA expression in human prostate cancer cell lines treated with dihydrotestosterone (DHT) continuously or intermittently. MATERIALS AND METHODS: Two prostate cancer cells having different status of androgen receptor [LNCaP (androgen dependent) and PC-3 (androgen independent)] were used in this study. To know the change in PSA and Drg-1 expression after DHT treatment the cells were cultured in steroid-free RPMI media for 24 hours. 10(-7) and 10(-8)M of DHT and 10(-7)M bicalutimide was added into the cells and then cultured for 72 hours. And we established in vitro IAD model using LNCaP cells. Northern analyses were performed to determine the expression level of both PSA and Drg-1genes. Also, western analyses were performed to determine the protein level of proliferating cellular nuclear antigen and androgen receptor. RESULTS: Transcripts of Drg-1 were detected in both LNCaP and PC-3 cells but PSA was not expressed in PC-3 cells. The expression of Drg-1gene in LNCaP cells was up-regulated by 10(-8)M of DHT like PSA gene and down-regulated by 10(-7)M bicalutamide. In the treatment of intermittent androgen deprivation, the expression pattern of Drg-1was similar to that of PSA. However, up-regulation of PSA was detected earlier than of Drg-1. CONCLUSIONS: Based on observation, Drg-1 was up-regulated by androgen and down-regulated by anti-androgen. This suggests that Drg-1gene is useful for determining the androgen independency of prostate cancer during IAD.

Three cases of orbital rhabomyosarcoma are reported here. Histological studies comfirmed the lesion 1:0 be the alveolar type in all cases. This tumor is a rare disease entity in Orient than Europe and America and accordingly, rarely encountered in our ophthalmologic practice, although it is the commonest primary malignant orbital tumor in children. Of the three cases reported here one occurred in adu1t and the other two in children. Case I. This 15 month old male showed a swelling of the left upper lid toward the medial side for 2 months and visited to our hospital on March 10, '69 with complaints of progressive swelling on the region with ptosis. The eye ball was slightly displaced toward the lower temporal side and ocular movement is limitted to upward. On palpation, the childthumb sized tumor was palpable in the upper nasal portion of the orbit. On excision of the tumor, the mass was found to be originated from the superior oblique muscle. The mass round measuring 2.5 X 2.5 X 1.5 cm in size. Histological diagnosis was alveolar rhabdomyosarcoma without cross-striation. No follow-up could be done. Case II. This patient of 15 month old male showed a swelling on the right lower lid existed 6 months and visited to our hospital on September 8, '69. The physical examination revealed that the left eye and the other routine examinations were within normal limits. The right eye showed the swelling of the lower lid, congestion of the palpebral conjunctiva, limitted movement of the eye ball toward the lower side and a palpable bean-sized mass on the region. The excision of tumor was performed under the general anesthesia. This mass was attached with the inferior oblique muscle with no other recognizable adhesion seemingly originating from that muscle. The mass was round and oval in shape, measuring 2 X 2 X 1 cm in size, diagnosis was alveolar rhabdomyosarcoma. The post-operative follow-up studies were unavailable. Case III. This case in one of adult alveolar rhabdomyosarcoma. At the age of 25 years, this man showed a proptosis of the right eye associated with migrain like headache, ocular pain and visual disturbance. This symptoms existed 6 months and gradually increased in intensity. On the physical examination, the left eye was found to be normal. The skull and orbit x-ray and c.b.c. were with in normal limits. The right eye revealed about 5mm proptosis compared with left eye and the adult thumb sized tumor was palpated on the inner side of the lower orbital rim. The visual acuity was in zero. The right optic disc was edematous and elevated about 4.0 D. The pupil showed marked dilatation and the light reflex was abscent and ocular movement was markedly limitted and eye ball is deviated toward the upper side. Under the general anesthesia, the exenteration of the orbit associated with the removal of tumor was carried out with no untoward complications. Origin of the mass was the inferior oblique muscle penetrating to the deeper part of the optic foraman and optic nerve was surrounded by the tumor completely Histology confirmed alveolar rhabdomyosarcoma. Follow-up study was impossible.

Myositis ossificans progressiva is a rare disease characterized by the formation of areas of calcification in the interstitial connective tissue of muscles, tendons, ligaments, fascia, and aponeuroses. There may be exacerbations and remissions of the disease, but the general course is an insidious loss of body motion, affecting especially the neck, spine and upper extremities and, rarely, the hips and lower extremities. It is commonly associated with various congenital anomalies. The cause is unknown and there is no known effective treatment. Myositis ossificans progressiva associated with brachydactyly of both great toes, in a 34 year old femaIe, is presented with a review of the literature. Chief complaints were ankylosis of the left knee and hip of 9 years duration. We performed biopsy of tubular bone which is placed antero-lateral side of the left knee.

The increased incidence of the trochanteric fracture of the femur was accompanied by the development of the vehicle and the prolongation of the average life-span. Recently it has been also increased in an active person from thirties to forties. 87 cases of the trochanteric fracture of the femur in 86 patients who have been admitted and treated at the Department of Orthopedic Surgery of Hanyang University Hospital during 8 years and 10 months, from May, 1972 to February, 1981, were reviewed. The results of this study were as follows: 1. The trochanteric fracture of the femur was more common in male and was frequent in a person who was from thirties to forties and who had vigorous social activity. 2. An injury from traffic accident was the most common cause of the fracture from thirties to forties and an injury from slip down was most common in seventies. 3. The unstable fracture which was classified by Evans' classification, Boyd and Griffin Type II Fx. and Tronzo Type III Fx. were most common in the intertrochanteric fracture and the Fielding Type II Fx. was most common in the subtrochanteric fracture of the femur. 4. Other injuries were accompanied by the trochanteric fracture of the femur in 38 patients (44.2%) and the pelvic bone fracture was the most common associated injury in these patients. 5. The weight bearing was allowed earlier in the patient who had been given the surgical Tx. than in the patient who had been given the conservative Tx. 6. In adults, there was no significant differences in the duration to achieve the bony union between the conservative treatment and surgical treatment performed. 7. We considered that the diminution of the probable complications by early weight bearing after accurate open reduction in accordance with the Type of the Fx. followed by secure internal fixation with devices is an ideal method of the Tx.

The present study was performed to compare maternal and perinatal outcomes in triplet and twin pregnancies with the result of ART(Assisted Reproductive Technology). Each pregnancy of 18 triplet pregnancies with 18 weeks or more was matched for maternal age, EDC(estimated date of confinement), parity, history of preterm delivery, indication of ART with two sets of twin pregnancies. Triplet pregnancies had a significantly shorter gestational age at delivery than twin pregnancies(30.4 versus 34.6 weeks), and a significantly lower mean birth weight(1,514 versus 2,286g). The mean hospital stay was significantly longer in triplets(22.3 versus 10.1 days). The incidences of 5 min Apgar score less than 7, neonatal deaths were significantly more often in triplets than twins; 18(33.3%) vs 6(8.3%), 15(27.8%) vs 7(9.72%), respectively. There were significant differences in the incidence of neonatal complications such as respiratory distress syndrome; 14(25.9%) vs 7(9.72%), ventilatory support; 18(33.3%) vs 5(6.9%), neonatal seizure; 9(16.7%) vs 0, btween the two groups. However, there were no significant differences between the groups in maternal complications or neonatal morbidity such as congenital malformations or hyperbilirubinemia, intraventricular hemorrhage, or bronchopulmonary dysplasia. We suggest that counseling patient regarding the anticipated perinatal outcomes of triplet pregnancies with the result of ART should be conducted with our data.
