Background : Communite-acquired peumonia (CAP) is one of the leading causes of mortality and morbidity. Despite progress in diagnostic techniques and treatments, management of pneumonia remains challenging, because the precise etiology remains uncertain in as many as 49% of cases. The limitaions of identifying etiologic agents make it necessary to use empiric antibiotics in almost all patients, and furthermore emergence of antibiotic-resistant organisms pose difficulties to the selection of an empiric antibiotic regimen. For the optimal choice of empirical antibiotics, we should know the frequency of etiologic agents and antimicrobial resistance rates in the community. Methods : A prospective multicenter study of community-acquired pneumonia in Korea was carried out between May 1997 and April 2000. The microbiologic diagnosis was based on the results of sputum culture, blood culture and pleural culture. Results : Five hundred eighty eight cases of community-acquired peumonia in 562 patients admitted to the hospitals. The mean age was 59.9 with male predominance (58.3%), and 370 (63%) had underlyin gillness. The etiologic agents were identified in 38.3%, and the list of individual agents, in decreasing order, was Streprococcus pneumoniae (21.7%), Klebsiella pneumoniae (14.8%) Pseudomonas aeruginosa (9.8%), Staphylococcus aureus (9.5%), viridans group streptococci (5.7%), Enterobacter cloacae (4.2%), Hemophillus Influenza (3.8%), The rates of admission to the intensive care unit was 10.4%. The motality was 7.1%. Susceptible rates of S. pneumoniae to penicillin was 36.6% and showed multidrug resistant. Forty percents of S. aureus were methicillin-resistant S. aureus. K. penumoniae were susceptible to cephalosporin and quinolone. Conclusion : In Korea, S.pneumoniae is the most important agent causing community-acquired pneumonia. Susceptible rates of S. pneumoniae to penicillin was 36.6% and showed multidrug resistant. Gram negative bacteria such as K. pneumoniae, P. aeruginosa showed high incidence when compared with that of other countries. Most of them had underlying diseases including bronchiectasis and chronic obstructive pulmonary diseases. (Korean J Infect Dis 33:1∼7, 2001)

To make high speed spindle system work properly, sensors with outstanding resolution and dynamic characteristics are essential. An optical fiber displacement sensor is based on simple principles. Electrical signal responds to the optical flux change due to the displacement change between a target and a sensor probe. In this paper, the performance of optical fiber displacement sensor has been investigated according to properties of optical fiber. Firstly, optical loss has been measured before and after polishing optical fiber endface. Secondly, allowance of optical fiber bending has been tested. thirdly sensitivity and linear range of the sensor has been found out according to the shape of cross section of optical fiber.

This paper is to develop an optical fiber displacement sensor for monitoring high speed spindle. Proper magnitude of optical power as well as amplification of output signal are necessary to improve sensitivity of the sensor. In this paper, to meet the need of improvement of the sensor resolution, we choose proper optical power and amplification level through speculating on optical power of a laser diode.

구토 후 발생한 토혈을 주소로 내원한 환자에서 좌측 늑막 삼출 동반 시 식도 파열의 가능성을 고려하여 흉수 천자 및 지속적인 흉부 단순 촬영의 추적관찰이 필요하며 식도 파열이 배제된 후 환자의 생체 징후 및 토혈 양을 파악하여 내시경 검사 시기를 신중히 결정하는 것이 좋을 것으로 생각된다. 본 증례는 토혈을 주소로 내원하여 Mallory-Weiss 증후군 의심 하에 내시경을 통한 치료 시행 후 추적 관찰에 의해 진단된 Boerhaave 증후군을 경험하였기에 보고하는 바이다. Boerhaave's syndrome is a spontaneous perforation of the esophagus most commonly resulting from a sudden increase in intraesophageal pressure combined with negative intrathoracic pressure caused by straining or vomiting. Surgery should generally be performed within 24 hours because mortality approached 30 to 50 percent in which surgery was delayed. Therefore, early diagnosis and prompt surgical repair are critical for survival. We have experienced a case of Boerhaave's syndrome in a patient presenting with hematemesis with left pleural effusion without any signs or symptoms of pneumomediastinum or pneumothorax.

Objectives: This study was performed to investigate whether ATP-sensitive K^(+) channels exist in interstitial cells of Cajal (ICC) of mouse small intestine and the physiological role of ATP-sensitive K^(+) channels in gastrointestinal motility. Methods: ICC were isolated from mouse small intestine and cultured for 2 days. Electrical activities of ICC were recorded using the whole-cell patch-clamp technique at 30°C. Results: ICC displayed rhythmic slow waves and spontaneous inward currents (pacemaker currents). Pinacidil, an ATP-sensitive K^(+) channel opener, induced membrane hyperpolarization and decreased amplitude of slow waves in current clamping mode. Also, pinacidil inhibited amplitude and frequency of pacemaker currents and activated outward currents at a holding potential of -70 mV. Pinacidil effects on slow waves and pacemaker currents were blocked by glibenclamide, a specific blocker of ATP-sensitive K^(+) channel. Forskolin, an activator of adenylate cyclase, induced membrane hyperpolarization and inhibited pacemaker currents like as pinacidil and blocked by glibenclamide. Conclusions: These results suggest that ATP-sensitive K^(+) channels exist in ICC and may be play an important role in regulating gastrointestinal motility through the modulation of pacemaker activities of ICC.

A 67-year-old male patient had coronary artery bypass graft. Before the induction of general anesthesia, 16 gauge central venous catheter was inserted via left subclavian vein. Initial chest anteroposterior (AP) radiograph showed adequate position, and the central venous pressure measurement through it was satisfactory. This patient's progress was satisfactory, and he was extubated on the second postoperative day. Daily chest AP radiograph had been unremarkable until the third postoperative day, when a right-sided pleural effusion was seen. A day later, the patient complained severe chest pain and dyspnea. We suspected perforation of superior vena cava wall by tip of central venous catheter on the chest computerized tomograph (CT). The injection of radiopaque dye through the central venous catheter confirmed spillage into the mediastinum on the chest CT. Right chest tube was inserted. The patient's condition dramatically improved after chest tube insertion. (Korean J Anesthesiol 2002; 43: 525~530)

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

Breast cancer in women pose a problem, and it can be difficult at times to evaluate the possibility of the cancer recurrence in node negative early cancer. The reliable prognostic markers are needed in breast cancer management to help clinicians identify the patient with the high risk of recurrence and arrive at more rational decisions for proper treatment. In order to investigate the prognostic significance of bcl-2, an immunohis-tochemical staining was performed in 35 tissue sections from paraffin blocks of primary breast cancer. Bcl-2 positivity was 43%. No relation could be observed between bcl-2 expression and known prognostic factors(tumor size, lymph node metastasis state, histologic grade, and nuclear grade), There was strong relation between bcl-2 expression and estrogen receptor positivity (ER) (P〈0.05). No relation is found between bcl-2 expression and c - erbB - 2 expression. These results suggest that bcl-2 expression is associated with a favorable prognostic factor(ER) but it is of no value as independent prognostic factor to the clinician in identifying the patients with high risk of recurrence.
