BACKGROUND: Hemoptysis is a common clinical symptom, responsible for 11% of admission to the hospital chest service. Correct diagnosis, accurate localization of the bleeding source and proper management are imperative to reduce the risk of massive hemoptysis. We performed the study to define the optimal time of fiberoptic bronchoscopy in 63 patients with hemoptysis admitted to Kyung Hee University Hospital between Aug 1989 and Aug1992. METHODS: Retrospective analysis of medical records concerning the cause, amount, duration of hemoptysis and the timing of fiberoptic bronchoscopy in 63(M:F=36:27) patients. RESULTS: 1) The main causes of hemoptysis were pulmonary tuberculosis(52.4%) bronchiectasis(27.0%) and lung cancer(11.1%). 2) The bleeding sites were localized in 26 Patients(41.3%). 3) The rates of localization of bleeding site were not related to the amount and duration of hemoptysis. 4) The rates of localization of bleeding site were 61.8%(21/34) during hemoptysis,18.2%(122) within 24hr after resolution of hemoptysis, 14.3%(1/7) thereafter. CONCLUSION: Early bronchoscopy, especially during hemoptysis may show higher rates of successful localization than delayed bronchoscopy.

We present a case of transient acantholytic dermatosis which developed on the face of a 19-year-old Korean girl. Asyrnptomatic pinhead to miliary-grain sized brownish papules arranged in a somewhat band-like outbreak along the left side of the nose for about 3 months. Histopathologic findings were similar to Dariers disease. Immunoperoxidase staining showed that IgG was deposited on the intercellular area of keratinocytes around the suprabasal clefts. Skin lesions disappeared spontaneously in 5 weeks after a skin biopsy.

Herpes Gestationis is a rare polymorphous, vesiculobullous disease of pregnancy and puerperium. It is characterized by rapidly progressive skin eruption heraled initially by severe generalized pruritus. Erythematous papules and urticaria like plaques rapidly appear followed by grouped, tense, vesiculobullous eruptions. A 23 year-old pregnant woman was admitted to our departrnent of dermatology hecause of erythematous patches with pruritic vesiculobullous and pustular eruption on the whole body since third week of conception, Biopsy specimen of bullous skin lesion showed spongiosis of epidermal cells, mild necrosis of basal cells, subepidermal bulla, edema, of papillary derrnis and perivascular infiltration of inflammatory cells. Ultrastructural findings showed mild necrosis of basal cells, bulla above or below basement membrane zone and partial separation of basal larnina. Direct immunofluorescences of bullous lesion and normal appearing skin demonstrated deposition of IgG in linear pattern along basement rnembra,ne zone. After treatment with systemic corticosteroid and antihistamin, the lesions were cleared, leaving residual hyperpigmentation, and she delivered normal female baby.

Cardiac tamponade with pleural and pericardial effusion is a rare but life-threatening complication of umbilical venous catheterization in the newborn. It requires a timely diagnosis and urgent treatment, such as pericardiocentesis, to save lives of affected patients. Recently, we experienced a 7 day-old, very low birth weight infant, who developed a cardiac tamponade with pleural and pericardial effusions complicated by umbilical venous catheterization. The patient was successfully treated with pleural and pericardial drainages. Here, we report this case with a review of literature, since there has been no such previous case reported in Korea.

OBJECTIVES: To estimate false-negative rate of cervical smears using Autopap 300 QC system in rescreening modality. METHODS: From September 1997 to December 1997, Total 26,983 cervical smears were obtained and 18,592 cervical smears were rescreened by Autopap 300 QC system with 10% review rate. The 274 cases of total 26,983 cervieal smears were confirmed histologically by colposcopic biopsy, cone biopsy and hysterectomy. The 274 cases of cervical smears, which obtained prior to pathologic diagnosis made, were evaluated based on cyto-histologic correlation and then the false negative rate were estimated. The cervical smears were reviewed, researching for the cause of false negative. RESULTS: (1) Histologic diagnosis of 274 cases include 65 cases of Low SIL, 173 cases of High SIL, 29 cases of SCC, 2 cases of adenocarcinoma in situ, and 5 cases of invasive adenocarcinoma. (2) The false negative rate were 3% (9/274). Those were 6.2%(4/65) of LSIL, 2.3% (4/173) Of HSIL, none of SCC and AIS, and 20%(5/1) of invasive adenocarcinoma. (3) The false negative cases were reviewed. The 6 cases were sampling enor and 3 cases were screening error. CONCLUSION: Using AutoPap 300 QC system in rescreening modality, The false negative rate of cervical smears were decreased, compared with our previous study.

This research proposes a safety strategy for coronavirus disease 2019 (COVID-19) walkthrough booths to optimize pandemic preparedness. These booths, designed for respiratory sample collection during the COVID-19 pandemic, effectively reduce infection risk and personal protective equipment-related fatigue among healthcare workers. However, inadequate disinfection and glove management could escalate infection transmission. Using computational fluid dynamics simulations, we analyzed droplet dispersion on booth surfaces and gloves under various wind conditions. Our findings suggest that when setting up COVID-19 walk-through booths, their location should be strategically chosen to minimize the effects of wind. All surfaces of booth gloves must be thoroughly disinfected with a certified disinfectant after nasopharyngeal swab collection. It is also recommended to wear disposable gloves over booth gloves when changing between patient examinations. In wind-affected areas, individuals nearby should not solely rely on the 2-meter distancing rule due to potential droplet spread from walk-through booths. We strongly recommend consistent and proper mask use for effective droplet blocking. Adherence to these guidelines can significantly enhance the safety and efficiency of walk-through booths, particularly in potential future pandemics.
