BACKGROUND: This study was performed to determine and compare the practice patterns of management of hypertension of the internists and family physicians in general hospitals and to compare them according to the JNC V guidelines. METHODS: Questionnaires were mailed to total 964 of internists and family physicians in general hospitals during May, 1996. 217 of them were returned with the response rate of 23.5%. Chi-square test and Fishers exact test were performed to examine the statistical difference between two groups. RESULTS: The mean age of the respondents was 39.1 and 77.9% of them were male. 65.4 % of hospitals for respondents were located in metropolitan cities. Concerning the number of measurements of blood pressure, 0.5% of the respondents measured just once before confirmation of the diagnosis. Items for physical examinations for initial evaluation were as follows; cardiac auscultation(94.0%), measurements of body weight and height(58.9%), abdominal examination(52.8%), auscultation for carotid bruit(41.7%), fundoscopic examination (25.6%). Regarding the laboratory tests, the frequency of evaluation of all item were higher than that of the physical examinations. For initial drug therapy, calcium channel blockers and ACE inhibitors were the most frequently chosen mediations. No difference was found between two specialties or tertiary and secondary hospitals in this trend. With educations for the life-style modification, 60-80% of the respondents educated the patients. No difference was found between two specialties except one item. CONCLUSIONS: As a whole the JNC V guidelines were not followed faithfully for the management of hypertension.

Generalized plane xanthoma is less common and usually involves the eyelids, lateral side of the neck, upper trunk, and extremities. Lesions, however, may appear on any portion of the body. Cutaneous xanthomas may occur in hyperlipidemic and in normolipidemic states. Generalized normolipidemic plane xanthoma is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance(MGUS). We wish to report two eases of generalized plane xanthoma associated with IgG monoclonal gammopathy of unknown significance.

Agminated lentigines may be defind as a circumscribed grouping of small pigmented macules arranged in a small or large group, often in a segmental pattern, each macule consisting of a lentiginous epidermal proliferation of melanocytes. We report five cases of agminated lentigines in otherwise healthy persons. Histologic exarnination of the pigmented lesion revealed findings consistent with lentigo simplex.

BACKGROUND: We conducted this study to verify whether a mechanical ventilator is adequate for cardiopulmonary resuscitation (CPR). METHODS: A self-inflating bag resuscitator and a mechanical ventilator were used to test two experimental models: Model 1 (CPR manikin without chest compression) and Model 2 (CPR manikin with chest compression). Model 2 was divided into three subgroups according to ventilator pressure limits (P(limit)). The self-inflating bag resuscitator was set with a ventilation rate of 10 breaths/min with the volume-marked bag-valve procedure. The mode of the mechanical ventilator was set as follows: volume-controlled mandatory ventilation of tidal volume (Vt) 600 mL, an inspiration time of 1.2 seconds, a constant flow pattern, a ventilation rate of 10 breaths/minute, a positive end expiratory pressure of 3 cmH2O and a maximum trigger limit. Peak airway pressure (P(peak)) and Vt were measured by a flow analyzer. Ventilation adequacy was determined at a Vt range of 400-600 mL with a P(peak) of < or = 50 cmH2O. RESULTS: In Model 1, Vt and P(peak) were in the appropriate range in the ventilation equipments. In Model 2, for the self-inflating bag resuscitator, the adequate Vt and P(peak) levels were 17%, and the P(peak) adequacy was 20% and the Vt was 65%. For the mechanical ventilator, the adequate Vt and P(peak) levels were 85%; the P(peak) adequacy was 85%; and the Vt adequacy was 100% at 60 cmH2O of P(limit). CONCLUSIONS: In a manikin model, a mechanical ventilator was superior to self-inflating bag resuscitator for maintaining adequate ventilation during chest compression.
