ABSTRACT
Streptomycin is currently utilized to treat advanced tuberculosis in Korea. However, the usefulness of intravascular streptomycin is not fully understood. In this study, streptomycin was administered intravenously in 30 patients. Intravenous administration of streptomycin may be a useful route of administration without undesirable toxicities.

We report a case of an infected pneumatocele in the course of anaerobic pneumonia in an adult. To the best of our knowledge, anaerobic pneumonia complicated by a pneumatocele in an adult has not previously been described. The pneumatocele occurred on the fifth day of hospitalization, and rapidly increased in size, with the development of a subsequent mixed anaerobe infection. A pig-tail catheter was inserted and the pus drained. The bacterial culture from the pus was positive for three anaerobes: Bacteroid species, Peptostreptococcus asaccharolyticus and Fusobacterium species. Intravenous antibiotics and percutaneous catheter drainage resulted in a successful treatment.

A functional upper airway obstruction due to a vocal cord dysfunction(VCD) is characterized by a paradoxical adduction of the vocal cords throughout the respiratory cycle with no obvious organic cause for the obstruction. It commonly occurs paroxysmally and imitates acute asthmatic attacks, often in patients with coexisting asthma. They present with episodes of dyspnea associated with inspiratory wheezing that persists despite conventional asthma treatment and a flattening of the inspiratory limb of the flow-volume curve; an adduction of the vocal cord during inspiration. Failure to recognize concurrent vocal cord dysfunction and asthma has led not only to the excessive use of bronchodilators and corticosteroids, but also to intubation and tracheostomy. Here, we report a case of coexistent obstructive pulmonary disease and functional upper airway obstruction due to a vocal cord dysfunction where a bronchoscopy showed a paradoxical vocal cord motion and typical features of a variable extrathoracic obstruction and a lower airway obstruction on the Flow-volume loop during a symptomatic period.

BACKGROUND: Joint symptoms frequently occur in the course of antituberculous chemotherapy and tend to be ignored and overlooked, but in some cases, they are often very troublesome in obstructing ordinary life. Joint symptoms that develop during antituberculous chemotherapy need to be understood, but there are few materials describing them systematically. METHOD: This study enrolled 33 patients with tuberculosis treated with first line antituberculous agents for more than 6months. In the course of treatment, joint symptoms not associated with specific cause, such as pre-existing joint disease or trauma, were investigated and compared with those of the asymptomatic group, We confirmed the incidence of joint symptoms and factors associated with them. RESULTS: Nineteen of 33 patients (58%) had joint symptoms. Joint symptoms developed 1.9±1.4 months after the beginning of chemotherapy and lasted for 3.6±2.5 months. IN 18 of 19 symptomatic patients, multiple joints were involved : shoulder(10 patients, 53%), knee(10,53%), finger(6,32%). Joint symptoms were expressed as pain(19 patients, 100%), stiffness(7,37%) and/or swelling (3,16%). Fourteen patients (74%) took analgesics to relieve their symptoms and in 2 patients, antituberculous agents were discontinued because of the severity of their symptoms. The symptoms seem to be caused by agents other than pyrazinamide, but it was very difficult to identify the definite causative agent. In age, sex, underlying disease and serum uric acid level, no significant differences were noted between the two groups. CONCLUSIONS: Although joint symptoms are common during antituberculous chemotherapy, their development is difficult to predict. Because some joint symptoms can become very bothersome, the physician should pay close attention to these symptoms.

BACKGROUND: The decision to institute mechanical ventilation for patients with COPD is very difficult. The accurate informaiton regarding weaning success and long-term survival will improve communication with patients and family and enhance informed consent. The aims of this study are to describe outcomes and identify variables associated with survival for patients experiencing mechanical ventilation with an acute respiratory failure of COPD. METHODS: The 53 cases of mechanical ventilation in the intensive care unit in the National Medical Center from 1989 to 1998 were included. Data were collected retrospectively from medical records. Weaning success rate and 3 month and 1 year survival rates were estimated. Factors associated with weaning success and survival were determined. RESULTS: Weaning success was 55%. For success group with 29 cases, 3 months survival rate was 61% and 1 year survival rate 37%. APACHE II scores in weaning success group were significantly lower than those in the failure group. Factors such as age, sex, comorbid-illnes, previous steroid use, causes of respiratory failure, RVH or arrhythmia on EKG, serum albumin level, arterial blood pH, PaO2, PaCO2, FEV1, duration of mechanical ventilation and steroid use during mechanical ventilation were not associated with weaning success. Only age and serum albumin level were associated with 3 month and 1 year survival. No COPD patients of age more than 75 years and serum albumin level less than 3g/dl had survived at 1 year after weaning success. CONCLUSION: While seaning success from mechanical ventilation can be predicted by APACHE IIscore in COPD patients, long-term outcomes of survivors may be influenced by nutritional status and age.

PCP remains the leading cause of deaths in patients with AIDS. As familiarity with PCP increases, atypical manifestations of the diseases are being recognized with greater frequency. There are following "atypical" manifestations of PCP; 1) interstitial lung response that include diffuse alveolar damage, bronchiolitis obliterance, interstitial fibrosis, and lymphoplasmocytic infiltrate 2) striking localized process frequently exhibiting granulomatous features 3) extensive necrosis & cavitation 4) extrapulmonary dissemination of the disease. A wide variety of pathologic manifestations may occur in PCP in human immunodeficiency virus- infected patienst and that atypical features should be sought in lung biopsies from patients at risk for PCP. We had experienced a case of PCP, which presented with severe hypoxia, progressive dyspnea and fine crackles. It was diagnosed as PCP in AIDS with manifestation of BOOP by open lung biopsy and showed good response to Bactrim & corticosteroid therapy.

BACKGROUND: Weaning is the process of switching a patient from mechanical ventilator to spontaneous breathing. A number of different weaning techniques can be employed. At recent study, conventional spontaneous breathing trial was superior to other techniques, such as intermittent mandatory ventilation(IMV) or pressure support ventiation(PSV). But adequate observation time of the spontaneous breathing trial was not determined. We reported the effectiveness of weaning and extubation following a 60 minutes spontaneous breathing trial with simple oxygen supply through the endotrachial tube. In this study, we tried to shorten the spontaneous breathing time from 60 minutes to 30 minutes. If weaning success was predicted after 30 minutes spontaneous breathing, extubation was done without reconnection with ventilator. METHODES: Subjects consisted of 42 mechanically ventilated patients from August 1994 to July 1995. The weaning trial was done when the patients recovered sufficiently from respiratory failure that originally required ventilatory assistance, the patients became alert and showed stable vital sign, and arterial O2 tension was adequated(PaO2>55 mmHg) with less than 40% of inspired oxygen fraction. We conducted a careful physical examination when the patients was breathing spontaneously through the endobronchial tube for 30 minutes. We terminated the trial if a patients was any of following signs of distress; cyanosis, diaphoresis, tachypnea(above 30 breaths per minute), and extreme tachycardia. Patients who had none of this features during spontaneous breathing for 30 minutes were extubated promptly. RESULT: 17 weaning trials of 15 patients were done in 42 mechanically ventilated patients. Successful weaning and extubation was possible in 14 trials of total 17 trials. In this 14 patients, 8 patients were extubated after 30 minutes spontaneous breathing, 3 patients were extubated after 60 minutes spontaneous breathing, and 3 patients needed over 3 hours for extubation from weaning. We found similar overall success rate compared with weaning following a 60 minutes spontaneous breathing trial. CONCLUISON: From the result of present study, we believe that weaning and extubation from mechanical ventilation following a 30 minutes spontaneous breathing with 02 supply through the endotracheal tube is a simple and effective method

A 68 year-old male was admitted with complaint of dyspnea and nonproductive cough which developed 6 hours after accidental inhalation of nitrogen dioxide. On admission, acute pulmonary edema and severe hypoxemia were found. With oxygen and bronchodilator therapy, diffuse alveolar consolitation and his dyspnea were improved from the following day. He was discharged at 8th hospital day with prednisolone 30mg daily for prevention of bronchiolitis obliteraus. During 6 weeks of follow up, there was no evidence of bronchiolitis obliterans.

Acute epiglottitis is a life threatening inflammatory disease of the upper airway mainly in children, however, the recent reports about acute epiglottitis in adults are increasing. The common symptoms are sore throat, dysphagia, dyspnea and salivary drooling. As the laryngeal edema progresses, the patient sits up, leans forward, with the chin thrust forward, having obvious difficulty breathing. Early recognition and proper airway maintenance until the inflammatory edema subsides are essential steps to avoid a possible life threatening upper airway obstruction. We experienced two cases of acute epiglottitis with sitting up position, chin thrust forward, having dyspnea.

BACKGROUND: The measurement of nonspecific bronchial hyperreactivity is valuable for diagnosis and management of bronchial asthma. Methacholine or histamine is used for the pharmacologic provocation test. Usually a methacholine bronchial provocation test is performed by a dosing technique with counted number of breaths. A dosimeter is indispensable in the dosing technique. Recently a timed tidal breathing technique which dose not need an expensive dosimeter was introduced. We measured the degree of nonspecific bronchial hyperreactivity to histamine using a simple timed tidal breathing technique. METHOD: Forty two healthy volunteers, 12 patients with bronchial asthma(BA), 10 patients with rhinitis(RH) and 10 patients with upper respiratory infection(URI) participated in the study. The subject's nose was clipped and inhalation continued during tidal breathing for 2 minutes via a face mask. FEV1 was measured at 30 seconds, 90 seconds after inhalation and inhalation of next solution was continued until there was a fall in FEV1 of 20%. Histamine PC20 was defined as the concentration at 20% fall of FEV1 and it was obtained from the log dose-response curve by linear interpolation. RESULTS: Inhalation of serial dilution of histamine could be performed in all patients without significant side of effects. The geometric mean±standard deviation of histamine PC20 in healthy volunteers is 8.27±2.22mg/ml, BA group 0.33±3.02mg/ml, RH group 0.85 ±3.24mg/ml, and URI group 1.47±1.98mg/ml. CONCLUSION: Histamine bronchial provocation test using timed tidal breath method is a simple and suitable tool for management of patients with bronchial hyperreactivity.
