A Case of Benign Metastasizing Pulmonary Leiomyoma / 결핵및호흡기질환

A benign metastasizing pulmonary leiomyoma (BMPL) is a rare disease that usually occurs in women with a prior or coincident history of uterine leiomyoma. Although leiomyoma is histologically benign, it has the potential to metastasize to a distant site such as the lung. A 35 year old woman who had undergone a hysterectomy due to uterine leiomyoma 5 years prior was admitted for an investigation of multiple pulmonary nodules on a routine chest roentgenogram. An open lung biopsy was taken to make a pathological diagnosis. The microscopic finding of the nodules was leiomyoma and was similar to those of the uterine leiomyoma that had been resected 5 years ago. The woman underwent wedge resections of all pulmonary nodules. This is the first case of BMPL in Korea, which was treated with wedge resections of all multiple pulmonary nodules.

Multicenter ICU Surveillance Study for Nosocomial Infection in Korea / 병원감염관리

Purpose: The purpose of this study is to determine the risk adjusted nosocomial infection (NI) rate and distribution of Nls and their causative pathogens in adult lCU. Methods: Prospective surveillance was performed at 12 lCU's of 5 acute care hospitals in Seoul and Kyonggi Do during a 3-months period from May to July 2002. The case finding was done by direct reviews of medical charts regularly for all patients by ICPs using CDC definitions. Results: Total NI rate was 10.18/1,000 patient-days in Medical-surgical ICU (MSICU) and 12.35/1,000 patient-days in Neurosurgucal ICU(NCI). Risk adjusted infection rate was 3.44 in indwelling catheter associated UTI 2.12 in central line associated BSI. 3.51/1,000 device-days in ventilator associated pneumonia in MSICU. There were 3.72, 2.26, 6.06/1,000 device-days in NCU. The infection rate by leu type showed no significant difference. The distribution of Nls were PNEU (28.99%). UTI (28.99%), BSI (18,84%), SSI(4.35%) in MSICU, and UTI(48.0%), PNEU(24.0%), BSI (14.0%), SSI(6.I) in NCU. The most commonly isolated organisms were Candida spp (38.6%), Enterococcus spp. (13.4%) in UTI, Staphylococcus aureus(36.2%), p. aeruginosa(18.8%) in PNEU and Coagulase negative staphylococcus(44.1%). S. aureus (14.7%) in BSL, S. aureus (19.8%) was the most common organism from overall nosocomial infections in the ICU, and 96.3% of S. aureus were MRSA. Conclusion: Distribution of site-specific nosocomial infection and isolated organisms were similar to the results of KOSNIC (Korea society for nosocomial infection control) surveillance in 1996. However, the total infection rate and a risk adjusted infection rate at MSJCU is lower than 1996's. This decrease is considered to be a result of efforts to prevention and control nosocomial infections.

A Multicenter Descriptive Study of Bloodborne Exposures among Health Care Workers in Seoul and Gyeonggi-Do / 병원감염관리

Background: The purpose of this study was to establish effective measures and preventive managements to the cases of bloodborne exposures among the health care workers. Method: We reviewed 331 cases that were reported to the infection control services of five hospitals from March 2000 to February 2002. The SPSS PC 10.0 was used to analyze the date. Result: The proportion of registered nurses, doctors, housekeepers, unrse aid and technicians were 48.0%, 27.8%, 10.0%, 6.0%, and 5.4% in order. The proportion of female exposures was 75.2%. Fifty six point eight percent of exposure have been working less than 3 years. The data also indicated that there were differences by their Occupations. Thirty nine point six percent of the exposures occurred at the general ward, and 16.6% of them occurred at the operation room and 13.0% of them occurred at the intensive care unit. Most of the bloodborne exposures occurred during blood sampling (26.3%), putting away the needle including the recapping(18.4%). and giving injection (14.5%). The major instruments of exposures were syring-needle (79.6%), blade (7.3%), suture needle (6.1%), and direct contact with blood (2.7%). The hands were the most common body parts of exposures (95.2%). The bloodborne pathogens were hepatitis B virus (HBV, 38.1%(126/331), hepatitis C virus (10.3%), syphilis (4.5%), and human immuno-dificiency virus (2.7%). Forty one point three percent(52/127) of health care workers(HCWs) usually didn't realize whether they had antibody to the HBV or not at the time of exposure; Seventy five percent (39/52) of them found out later to be positive for HBV antibody. Only 48.7% (19/39) of them could get the medical treatment since they didn't know about immunity before the test. The cases with completion of management at the time of exposure, those of follow-up evaluations, and the cases with lost follow-up were 40.7%, 38.6% and 20.7%. in order. None of the cases were led to actual infections. Conclusion: The results from this study can be applied to establish effective measures of prevention and managements of the bloodborne exposures among the HCWs. If the laboratory data of HCWs were available at the time of exposure, more effective management would be possible. Also the results from this study emphasized the need for the systematic and practical follow-up.

Differential Diagnosis By Analysis of Pleural Effusion / 결핵

BACKGROUND: Pleural effusion is one of most common clinical mainifestations associated with a variety of pulmonary disease such as malignancy, tuberculosis, and pneumonia. However, there are no useful laboratory tests to determine the specific cause of pleural effusion. Therefore, an attempt was made to analyze the various types of pleural effusion and search for useful laboratory tests for pleural effusion in order to differentiate between the disease, especially between a malignant pleural effusion and a non-malignant pleural effusion. METHODS: 93 patients with a pleural effusion, who visited the Severance hospital from January 1998 to August 1999, were enrolled in this study. Ultrasound-guided thoracentesis was done and a confirmational diagnosis was made by a gram stain, bacterial culture, Ziehl-Neelsen stain, a mycobacterial culture, a pleural biopsy and cytology. RESULTS: The male to female ratio was 56:37 and the average age was 47.1±21.8 years. There were 16 cases with a malignant effusion, 12 cases with a para-malignant effusion, 36 cases with tuberculosis, 22 cases with a para-pneumonic effusion, and 7 cases with transudate. The LDH2 fraction was significantly higher in the para-malignant effusion group compared to the para-pneumonic effusion group [30.6±64.% and 20.2±7.5%, respectively (p<0.05)] and both the LDH and LDH2 fraction was significantly in the para-malignant effusion group compared to those with tuberculosis [16.4±7.2% vs. 7.6±4.7%, and 30.6±6.4% vs. 17.6±6.3% respectively (p<0.05)]. The pleural effusion/serum LDH4 fraction ratio was significantly lower in the malignant effusion group compared to those with tuberculosis [1.5±0.8 vs. 2.1±0.6, respectively (p<0.05)]. The LDH4 fraction and the pleural effusion/serum LDH4 fraction ratio was significantly lower in the para-malignant effusion group compared to those with tuberculosis [17.0±5.8% vs. 23.5±4.6% and 1.3±0.4 vs. 2.1±0.6, respectively(p<0.05)]. CONCLUSION: These results suggest that the LDH isoenzyme was the only useful biochemical test for a differential diagnosis of the various disease. In particular, the most useful test was the pleural effusion/serum LDH4 fraction ratio to distinguish between a para-malignant effusion and a tuberculous effusion.

A Case of the Hepatic Hydrothorax in the Absence of Ascites Confirmed by Tc-99m Macroaggregated Serum Albumin Scan / 결핵

Pleural effusion due to hepatic cirrhosis with ascites is well known, although hepatic hydrothorax in the absence of ascites is a rare condition, the pathogenesis of which is still unknown. We report a case of hepatic hydrothorax without ascites confirmed by the intraperitoneal injection of Tc-99m macroaggregated serum albumin (Tc-99m MAA) that demonstrated the passage of Tc-99m MAA into the right pleural cavity.

A Prospective Study of Ziehl-Neelsen Stain and Mycobacterial Culture of Pleural Fluid and Closed Pleural Biopsy Specimen in Tuberculous Pleural Effusion / 감염

BACKGROUND: Tuberculous pleural effusion is the most common extrapulmonary site of all disease due to Mycobacterium tuberculosis. The diagnosis of tuberculous pleural effusion is most often established by histologic examination of pleural biopsy specimens. This study documents the utility of smear and culture of pleural fluid and pleural biopsy specimens for tubercle bacilli. METHODS: Between March 1998 and August 1999, we performed thoracentesis with or without pleural bio-psies on 148 patients with pleural effusion according to protocol with Abrams needle. Before the pleural biopsy, a diagnostic thoracentesis was performed. Aliquots of pleural fluid (30 mL) were submitted for biochemical, cytologic, and bacteriologic studies, Ziehl-Neelsen staining and culture in Lowenstein-Jensen medium. At least five samples of parietal pleural tissue were obtained, one for mycobacterial study and another for histologic study. RESULTS: Thirty-seven of the 148 patients were proved to have tuberculosis (24 men and 13 women) with a median age of 32 years (range, 21~91). Pleural biopsy was performed on 35 of the 37 patients with tuberculous pleural effusion. Granuloma was present in 33 of the 35 patients investigated with acid-fast bacilli in 9 patients. The smear for acid-fast bacilli of pleural fluid was positive in 1 patient and the culture for M. tuberculosis was positive in 5 of 37 patients. Pleural biopsy culture was positive in 3 of 35 patients. The 2 patients who could not carry out the pleural biopsy were positive in pleural fluid and pleural tissue mycobacterial culture, respectively. CONCLUSION: In our test, Ziehl-Neelsen staining and culture for M. tuberculosis of pleural fluid and pleural specimen gave a higher yield (5.4%) than the histologic methods alone in establishing the diagnosis of tuberculous pleural effusion.

A Case of acute respiratory distress syndrome induced by all-trans-retinoic acid / 결핵

Acute respiratory distress syndrome (ARDS) has been reported to be associated with a variety of medical and surgical conditions, including All-trans-retinoic acid (ATTA). ATRA is very efficaceous drug to acute promyelocytic leukemia (APL). This drug can induce complete remission at APL without fatal risk of disseminated intravascular coagulation. But ATRA treatment, sometimes, produces the symptoms of fever, weight gain and acute respiratory distress, renal function impairment. The causes of these symptoms are not fully proved, but supposed as the result of leukostasis and capillary leak syndrome from excessive leukocyte differentiation and cytokines release. Recently, we experienced a 24-year-old woman who complained gum bleeding for 6 days. At bone marrow biopsy, she was diagnosed as APL. 2 days after ATRA treatment, she was suffered from the symptoms of dyspnea and general ache. At laboratory examination, total leukocyte count was 50,400/mm3 PaO2 was 42.5 mmHg and chest PA revealed the findings compatible with ARDS. Treatment with low dose ara-C, corticosteroid and general supportive cares were tried. Within 3 days after treatment, the patient recovered from ADRD by evidence of arterial blood gas study and chest radiographs. She has acquired complete remission of APL with maintenance of ATRA. And so, we present this case with a review of related literatures.

One Case of Tracheal Rupture after Blunt Chest Trauma Diagnosed Early by Fiberoptic Bronchoscopy / 결핵

Tracheobronchial rupture is one of the less-common injuries associated with blunt chest trauma. The diagnosis of tracheobronchial rupture is not easy, but failure to diagnosis may lead to death or long-term disability. Early diagnosis and appropriate management can reduce the mortality and morbidity. Bronchoscopy is the diagnostic method of choice for patients with tracheobronchial rupture. We report a case of tracheal rupture after blunt chest trauma. A 40-year-old man was transferred to our hospital for dyspnea after blunt chest trauma. He was promptly diagnosed as tracheal rupture by fiberoptic bronchoscopy and chest computed tomogram. He was successfully managed by thoracotomy and primary repair.

Urinary 5-hydroxyindoleacetic acid (5-HIAA) excretion before and during cisplatin chemotherapy in patients with intrathoracic malignancy / 결핵

BACKGROUND: Nausea and vomiting associated with chemotherapy are common side effects which remain difficult to control. Acute phase nausea and vomiting (0-24 hours after induction of chemotherapy) parallels plasma serotonin release, which explains the effectiveness of 5-HT3 receptor antagonists. Serotonin released from gastrointestinal enterochromaffin cells may mediate chemotherapy-induced emesis. In this study, we analyzed urinary excretion of 5-HIAA, the main metabolite of serotonin. METHODS: Eight men and four women were studied in their cisplatin chemotherapy cycle. Urinary 5-hydroxyindoleacetic aicd (HIAA) levels were determined before and during a 24-hour period under ondansetron prophylaxis. RESULTS: Urinary 5-HIAA excretion for a 24-hour period was increased in all patients after induction of cisplatin (P=0.002). CONCLUSION: Cisplatin chemotherapy is associated with serotonin release in the acute phase. Our finding provides evidence for a relationship between emesis and serotonin following cisplatin chemotherapy.

Comparison of the Role of CT and Fiberoptic Bronchoscopy in the Diagnosis of Hemoptysis / 결핵

BACKGROUNDS: To investigate the role of CT as a screening tool and to compare the diagnostic accuracy with that of the fiberoptic bronchoscopy (FOB) in evaluating the causes of hemoptysis. METHODS: The retrospective review of plain chest radiograph, CT and FOB was done in 72 patients with hemoptysis. The diagnosis were confirmed by histology (n=33), bacterial culture (n=6), cytology (n=3), serology (n=2), skin test (n=1), clinical response (n=5), and airway disease mainly by HRCT (n=22). RESULTS: The causes of hemoptysis were shown to be lung cancer (n=29), bronchiectasis (n=19), tuberculosis (n=12), aspergilloma (n=5), invasive aspergillosis (n=1), COPD (n=3) and others (n=3). The sensitivity was 100% and 91,7% by CT and FOB respectively. The diagnostic compatibility was 95.8% and 59.7% by CT and FOB respectively. The diagnostic compatibility in cases with central airway disease was 96.3% and 100% in CT and FOB. In parenchymal disease, CT and FOB showed 91.3% and 43.5% of compatibility, respectively. In airway disease, CT and FOB showed 100% and 31.8% compatibility, respectively. That is to say, CT has higher sensitivity and diagnostic compatibility than FOB for identifying the causes of hemoptysis, and is more helpful for patients with hemoptysis from parenchymal or airway disease. FOB had the advantage in obtaining histologic, cytologic and bacteriologic diagnosis with biopsy or washing. CONCLUSION: CT should be used as the screening method before performing FOB for patients with hemoptysis who have normal or nonspecific findings or 3 peripheral airway disease in plain chest radiograph.

A Case of Epithelioid Hemangioendothelioma Involving the Lung and Liver / 결핵

Epithelioid Hemangioendothelioma(EH) is a rare vascular tumor, originating from endothelial cells. The principal locations are lung, soft tissue, bone and liver. This tumor is of borderline malignancy, relatively benign course. In the lung, the tumor is often multifocal, bilateral and frequently lead to the mistaken diagnosis of metastatic carcinoma. Although EH of the lung is relatively slow growing tumor, extensive pulmonary involvement, systemic metastasis, mainly to the liver have been documented. A 26-year-old man with EH involving the lung and liver was reported. Chest X-ray and chest CT showed multiple nodules in both lung fields and Abdominal CT multiple round low densities in liver. Transbronchial lung biopsy was performed. The patient diagnosed as EH by light microscopic finding and immunohistochemical study for Factor VIII-related antigen.

A Clinical Review of Primary Tracheal Carcinoma / 결핵

BACKGROUND: Primary malignant tumors of the trachea are extremely rare entities and account for a mere 0.1 percent of all malignancies of the respiratory tract Because of vague localizing signs, symptoms and a usually negative routine chest film, the patients with tracheal tumors are often treated for asthma or chronic obstructive pulmonary disease for considerable period of time before correct diagnosis. METHODS: We Have made a review of the 17 cases of primary tracheal tumors in recent 15 years. We reviewed the clinical features including history of smoking arid respiratory symptoms, the official readings of initial routine chest film, the cytologic examination of sputum, the time of delay in diagnosis, and the response according to the therapeutic modalities. RESULTS: Eight out of 9 patients with squamous cell carcinoma(SCC) were above 50 years old, five out of 6 patients with adenoid cystic carcinoma(ACC) were below 50 years old. The most common location of primary tracheal tumors was the upper one-third of trachea in 8 cases(47%). The most frequent symptoms were dyspnea in 13/17 cases(76%) and then strider or wheezing, cough, and sputum in order. The routine chest roentgenographic examinations wore not helpful to diagnose tracheal carcinoma and the cytologic examinations of sputums were helpful to diagnose tracheal carcinoma in only one case with adenocarcinoma. The mean times of delay in diagnosis of patients with SCC and ACC were S months and 24.9 months respectively. We bad bronchial asthma in 8 cases(47%) and tracheal tumors in 4 cases(23%) as initial clinical impression CONCLUSION: We would like to perform more comprehensive diagnostic too]s(high KVP technique, the fibroptic bronchoscopic examination, chest CT scan etc.) in patients who had the suggestive points for the tracheal tumors(1. unexplained hemoptysis or hoarsness, 2. inspiratory wheezing or stridor, 3. wax arid waning of dyspnea according to changes of position. 4. progressive asthmatics unresponsive to antiasthmatic therapy) and radical resection of tumor or external radiation therapy with curative aim as possible.

A Case of Wegener's granulomatosis with obstruction of both anterior tibial and peroneal arteries / 결핵

Wegener's granulomatosis is characterized by necrotizing granulomatous vasculitis affecting upper and lower respiratory tracts and kidneys. Vascular lesions commonly involve capillaries and small vessels but, less commonly larger vessels. We report a 46-year-old male patient of Wegener's granulomatosis associated with paranasal sinusitis, pulmonary consolidations, glomerulonephritis, skin lesions with obstruction of both anterior tibial and peroneal arteries. Several necrotic lesions of the toes had progressed to gangrene and both transmetatarsal amputations were done. The patient continued to receive cyclophosphamide and prednisolone.

A Case of Hepatic Tuberculosis Diagnosed by Peritonescopy with Liver Biopsy / 대한소화기내시경학회지

Studies on hepatic tuberculosis are rare in Korea except several case repots. This is the first report on hepatic tuberculosis confirmed by the peritoneoscopic liver biopsy in Korea. A 43-year-old man was admitted due to high fever and cough for l0 days. On physical examination moist rale was audible on the both lower lung fields and hepatomegaly was noted. Chest X-ray revealed multiple fine granularity scattered uniformly throughout the both lung fields compatible with miliary pulmonary tuberculosis. On blood chemistry, SGOT, SGPT and alkaline phosphatase were elevated. Peritoneascopy revealed multiple yellowish-white small nodules evenly acattered on the entire surface of the both lobes of the liver and the needle biopsy of the liver showed chronic granulomatous inflammation with multinucleated giant cells and caseous necrosis consistent with hepatic tuberculosis. The patient was treated with antituberculous medications. Chest X-ray 6 months after treatment revealed completely healed miliary pulmonary tuberculosis and on blood chemistry 200 days after therapy SGOT, SGPT and alkaline phosphatase were within normal limits.
