A comparative investigation on the effect of ampicillin and procaine penicillin in the treatment of uncomplicated male gonorrhoea is presented. Three hundred and twenty eight male patients with uncomplicated gonococcal urethritis at a Venereal Disease Center in Seoul was subjected to this study. 164 patients were treated with 3.5 gm ampicillin plus l.0 gm probenecid, and 87 patients were followed. There were 16 (18.4%) failures and 15(21.1%) postgonococcal erethritis(PGU). Other 164 patients were treated with 4.8 million units produced penicillin plus 1.0gm prohenecid, and 73 patients were followed. There were 11 (15.1%) failures and 11(17.7%)PGU. There was no statistically significant difference of effect in the treatment of gonorrhoea between above two drugs. It is suggested that ampicillin plus probenecid is as effective as procaine penicilIin plus probenecid in the treatment of uncomplicated male gonococca1 urethritis.

The lesions of central nervous system in tuberous sclerosis often calcify, especially those present in the perivascular region, allowing the computed tomography to make early and definite diagnosis, even when patients intelligence was normal, seizures were absent, or clinical findings were not specific, We report three cases of tuberous sclerosis, which showed pathognomic subependymal paraventricular calcification in brain CT.

The idiopathic calcinosis of the scrotum (Shapiro, 1970) is usually multiple, asymtomatic nodules of the scrotal skin which begins m childhood or early adult life, increase in the size and numbers, and sometimes breakdown to discharge chalky contents. Clinically they are most often misdiagnosed as cysts. The forty eight years old male patient visited our hospital on Oct. 14, 1980, because of multiple asymtomatic scrotal masses which are pin head to walnut sized. There is no family history of calcification, scrotal or otherwise. Histology shows naked amorphous masses in the dermis without any evidence of residual cysts, and is acicular clefts in the masses. Most of the tumors were surgically removed in 5 sessions.

Lichen sclerosus et atrophicus (LSA) is an uncommon condition of the skin with small white macular or atrophic plaques which predominantly affects the genital regions of middle aged and elderly women. We present an atypical case of LSA on a 58 year old woman. The patient had a brownish-black colored patch of 2.5 * 7.0 cm in size on the right clavicular area of one year's duration. The histopatholgy of the lesion disclosed classical findings of LSA. A marked incontinence of pigment is noted in the upper dermis which accounts for the clinical picture of the lesion. She was treated with topical hydrocortisone cream resulting in a marked diminution of pigmentation.

Both idiopathic pulmonary fibrosis (IPF) and pulmonary involvement of collagen vascular disease(CVD) are well known cause of diffuse interstitial lung disease which lead to fibrosis and honeycombing. We analyzed HRCT findings of 33 patients with IPF and 14 patients with CVD in terms of predominant pattern, site of involvement, mediastinal lymph node enlargement, pleural change and pulmonary volume loss. Criteria of mediastinal lymph node enlargement and pleural thickening were 15mm in long diameter and 3mm, respectively. Volume loss of the lung was measured by using hilar height ratio (apex to hilum/hilum to diaphragmatic dome). Mean age was 61 years for IPF and 46 years for CVD and male: female ratio was 27:6, 4:10, respectively. Predominant HRCT pattern was honeycombing for IPF (63%), and ground-glass opacity for CVD (66%) (p=0.001). Predominantly, subpleural involvement was seen in 90% for IPF and 74% for CVD. Mediastinal lymph node enlargement was seen in 47% of the patient with IPF and 14% with CVD (p=0.004). pleural thickening was seen in 97% of the patients with IPF and 42% with CVD (P=0.002), Pleural effusion was seen in 10% of the patients with IPF and 36% with CVD (P=0.009). Hilar height ratio of more than 1.5 was seen in 84% of the patients with IPF and 29% with CVD. In conclusion, our study shows that patients with IPF are prone to have more progressed stage of pulmonary fibrosis than the patients with CVD on HRCT.

The recent discovery of plasmid derived beta-lactamase production by N. gonorrhoeae has changed the outlook of treatment of gonococcal infections and may well become the single most important factor in gonorrhoea control. Penicillinase is a beta-lactamase that splits the beta-lactam ring of penicillin hetween the C and N atoms to form penicilloic acids. We have been trying to assess the prevalence of PPNG in Korea since May 1980. We report here 7 strains of beta-lactamase producing N. gonorrhoae detected by chrornogenic cephalosporin method from Jan. 1981 to Mar. 1981 at the Joong Ku puhlic health center in Seoul. In January, I strain (l.3%); February, 2 strains (5.0%); and March, 4 strains .(6 4%) have been isolated. All restrains were confirmed by sugar feriventation test. Previously only one strain of PPNG had been reported among Korean laymen. The sudden appearance of PPNG among Korean laymen in 1981 may mean the barruer between U.S. Army enc1aves and Korean public has been broken recently and/or direct irnport of PPNG frorn abroad especially from South East Asia.

Purpose: This study is to explore the antecedent factors of daycare teacher behaviors concerning the eye health of preschool children by applying an extended parallel process model. Methods: Focus group interviews were conducted with ten daycare center teachers on September 4 and 14, 2023. A data analysis was performed according to the content analysis method by clustering the data into the four categories: the two threat factors of severity and susceptibility and the two efficacy factors of self-efficacy and response-efficacy. Results: Daycare center teachers’ perception of the severity of eye health problems in preschool children was high in relation to eye trauma, but it was recognized that viewing the electronic devices were of a less severe because symptoms were not noticed in a short period of time. They also showed low susceptibility because they were not sufficiently interested in the eye health hazard behaviors of preschool children. The self-efficacy of daycare center teachers was low because this was a lack of knowledge about symptoms of eye problems. However, they recognized that eye health activities performed in the preschool age could prevent negative eye health outcomes, thus showing a high response efficacy. Conclusion In the future, it is necessary to increase the sensitivity and engagement of daycare center teachers concerning with the eye health of preschool children and to increase their self-efficacy. It will also be necessary to develop various interventions to improve eye health for preschool children that can be implemented by daycare center teachers.
