Background : pH measurement is an important test in assessing the etiology of pleurisy and in identifying complicated parapneumonic effusion. Although the blood gas analyzer is the gold standard method' for pleural pH measurement, pH meter & pH strip methods are also used for this purpose interchangably. However, the correlation among the pH data measured by the three different methods needs to be evaluated. In this study, we measured the pH of pleural fluid with the three different methods respectively and evaluated the correlation among the measured data. Methods : From August 1999 to March 2000, we measured the pleural fluid pH in 34 clinical samples with three methods-blood gas analyzer, pH meter, and pH strip. In the blood gas analyzer and pH meter methods, the temperature of pleural fluid was maintained around $0^{\circ}C$ in air-tight condition before analysis and measurement was performed within 30 minutes after collection. As for the pH strip method, the pleural fluid pH was checked in the ward immediately after tapping and in the clinical laboratory of our hospital. This part is unclear. Results : The causes of pleural effusion were tuberculosis pleurisy in 16 cases, malignant pleural effusion 5 cases, parapneumonic effusion 9 cases, empyema 3 cases, and congestive heart failure 1 case. The pH of pleural fluid (mean$\pm$SD) was 7.34$\pm$0.12 with blood gas analyser, 7.52$\pm$0.25 with pH meter, 7.37$\pm$0.16 with pH strip of immediate measurement and 6.93$\pm$0.201 with pH strip of delayed measurement. The pH measured by delayed pH strip measurement was lower than those of other methods (p<0.05). The correlation of the results between the blood gas analyzer and pH meter(p=0.002, r=0.518) and the blood gas analyzer and pH strip of immediate measurement(p<0.001, r=0.607). Conclusion : In the determination of pH of pleural fluid, pH strip method could be a simple and reliable method under immediate measurement conditions after pleural fluid tapping.

Purpose This study investigated whether the respiratory phase during pleural puncture in CT-guided percutaneous transthoracic needle biopsy (PTNB) affects complications. Materials and Methods We conducted a retrospective review of 477 lung biopsy CT scans performed during free breathing. The respiratory phases during pleural puncture were determined based on the table position of the targeted nodule using CT scans obtained during free breathing. We compared the rates of complications among the inspiratory, mid-, and expiratory respiratory phases. Logistic regression analysis was performed to control confounding factors associated with pneumothorax. Results Among the 477 procedures, pleural puncture was performed during the expiratory phase in 227 (47.6%), during the mid-phase in 108 (22.6%), and during the inspiratory phase in 142 (29.8%). The incidence of pneumothorax was significantly lower in the expiratory puncture group (40/227, 17.6%; p = 0.035) and significantly higher in the mid-phase puncture group (31/108, 28.7%; p = 0.048). After controlling for confounding factors, expiratory-phase puncture was found to be an independent protective factor against pneumothorax (odds ratio = 0.571; 95% confidence interval = 0.360-0.906; p = 0.017). Conclusion Our findings suggest that pleural puncture during the expiratory phase may reduce the risk of pneumothorax during image guided PTNB.

Purpose: To evaluate the drainage effect of silk suture material following aspiration of the bursa as an early treatment of chronic prepatellar bursitis. Materials and Methods: Twelve cases, which have over two weeks of history and over one year of follow-up, were investigated. The average duration of follow-up was 18.3 months. The average symptom duration before introduction into this study was 2.2 months. With an aseptic technique, the aspiration of the bursa was done with spinal needle or injection needle and syringe and then the insertion of silk suture material through the aspiration needle was performed. Over one year follow-up, recurrence, infection, pain, and limitation of range of motion were investigated by telephone interview. Results: Redness around the insertion site of silk suture material was found in all cases, but there was no development of active infection in eleven cases. At five days after procedure, a supprative infection was developed in one case. The results were considered satisfactory in 92% of cases and the average duration of treatment is 14.5 days. Conclusion: The drainage with silk suture material following aspiration of the bursa is effective and less invasive method in the early treatment of chronic prepatellar bursitis.

Purpose: Urinary tract infection (UTI) is the most common serious bacterial infection in infants younger than 3 months of age. Lumbar puncture is routinely performed to evaluate febrile young infants for sepsis. However, there is no clear consensus on the use of routine lumbar puncture to diagnose concomitant meningitis in infants with UTI. We evaluated the prevalence of coexisting bacterial meningitis and sterile cerebrospinal fluid (CSF) pleocytosis in young infants with UTI. Methods: We retrospectively reviewed the medical records of 85 infants with UTI, aged from 29 to 99 days, who were admitted to Daegu Catholic University Medical Center from January 2013 to May 2016. We included 80 patients who had undergone lumbar puncture. Demographic features, clinical features, and laboratory findings were analyzed. Patients were divided into two groups based on the presence of sterile CSF pleocytosis and we compared these groups and assessed the differences between them. Results: Of the 80 UTI patients enrolled, 34 (43%) had sterile CSF pleocytosis. None had bacterial meningitis, and CSF polymerase chain reaction for enterovirus was positive in two patients without CSF pleocytosis. There were no significant differences between the two groups with regards to age, body temperature, peripheral white blood cell count, urinalysis, and duration of hospital stay. Conclusions: Though sterile CSF pleocytosis is common in young UTI patients, coexisting bacterial or viral meningitis is very rare. Indications for lumbar puncture in these patients depend on clinical condition.

종래의 영상진단 방법은 골수의 이상을 검사하는데 상당한 제한점이 있는 상황에서 MR 영상은 골수를 칩습한 병변을 직접 묘출할 있는 우선적인 영상진단법으로 그 이용이 점차 증대되고 이다. 비록 골수 천자나 생검에 비해 조직학적 진단의 특이성은 떨어지나 환자의 임상증세와 혈액상을 연관지어 MR 영상 소견을 판독하면 골수의 병변을 진단하고 그 치료에 관한 반응을 해석하는데 유용한 정보를 줄 수 있으리라 기대된다.

In young adolescent girls, anorexia nervosa is a significant cause of weight loss, and hospital admissions among children and adolescents. Anorexia nervosa is a life-threatening disorder, with about one-third of deaths caused by cardiac complications. A high rate of pericardial effusion has been recently reported in patients with anorexia nervosa, although relatively few cases require pericardiocentesis. Here, we describe three patients with anorexia nervosa who were diagnosed with large pericardial effusions. To prevent cardiac tamponade, pericardiocentesis was performed in two girls.

We report an unusual case of left atrial auricular abscess which was successfully treated by surgical resection, treatment with antibiotics and mediastinal irrigation. A 9-year-old female patient with previous history of urinary tract infection was admitted because of persistent fever. Echocardiography and magnetic resonance imaging revealed massive pericardial effusion and a mass lesion at the left upper cardiac border. Pericardiocentesis isolated Staphylococcus aureus on culture. The patient underwent mass removal under cardiopulmonary bypass. The mass was located within the left atrial auricular wall with fibropurulent abscess formation inside. Postoperative mediastinal irrigation was performed. Pathologic examination of the mass showed organized thrombi with chronic fibrosing mural endocarditis. She discharged on the 21st postoperative day without complication.
