From March 1987 to July 1989, six patients (five dadults and one child) with lung abscess (size, 5-13cm in diameter) were treated with percutaneous aspiration and drainage. In each case, the puncture was made where the wall of the abscess was in contact with the pleural surface. An 8 to 10 Fr catheter was inserted for drainage. Five of 6 had a dramatic clinical response within 24 hours of the drainage. Percutaneous drainage was successful with complete abscess resolution in four and partial resolution in one patient. No response was seen in the rest one. The duration of drainage ranged from 7 to 18 days (average, 15.5days) in successful cases. One case of the failure in drainage was due to persistent aspiration of the neurologically impaired patient. In one patient, the abscess resolved after drainage but recurred after inadvertent removal of the catheter 7 days after insertion. In two patients, concurrent pleural empyema was resolved completely by the drainage. Computed tomography provided anatomic details necessary for choosing the puncture site and avoiding a puncture of the lung parenchyma. Percutaneous catheter drainage is a safe and effective method for treating patients with lung abscess.

Background: Fall prevention is important for reducing hip fractures. The aim of this study was to determine the relationship between variables related to hip fractures according to sex and season. Methods: This study included patients admitted for fragility hip fractures between 2012 and 2021. Patients were interviewed by a junior resident before discharge. Data on sex, age, diagnosis, osteoporosis treatment, direction, voiding problems, ambulatory function, seasons, weather, time of day, place, location, floor condition, activity during fall, and perceived reason for fall were collected and analyzed. Results: A total of 1,118 patients were included (279 males and 839 females). In both sexes, indoor falls were prevalent throughout all seasons, but males showed a higher proportion of outdoor falls, especially in winter during cloudy or snowy weather. Rooms and walking were the most common locations and activities during falls. The poor ambulatory function was associated with a higher prevalence of indoor falls. Osteoporosis treatment rates were low and did not differ according to Koval stage. Winter was associated with higher osteoporosis non-treatment group. Urgency/incontinence in female patients caused a higher proportion of falls during the evening time. Conclusions Strategies for indoor fall prevention and vigilant osteoporosis diagnosis and treatment are important for all seasons, especially for frail elderly patients. Outdoor fall prevention emphasized for male patients, and education around nighttime falls should be provided for female patients with voiding dysfunction.

Liver is generally known as an organ which is most commonly involved by the metastic tumors. According to the tendency of using fine needle aspiration in the diagnosis of hepatic tumors, the differentital diagnosis between hepatocellular carcinoma and metastatic carcinoma frequently has been a main issue in the poorly differentitated cases, especially to the pathologists of Korea, an endemic area of hepatocellular carcinoma. Until now the problem has been usually solved by the comparison of cytologic characteristics of their tumor cells but not by background cytologic features which rarely have been studied. We observed the background cytologic features helpful for the differential diagnosis through the analysis of 20 cases who had confirmed primary cancer and were diagnosed as metastatic carcinomas in the liver by fine needle aspiration cytology. Twenty cases included 9 adenocarcinomas, 7 spuamous cell carcinomas, 1 small cell carcinoma, 1 carcinoid, 1 adenoid cystic carcinoma, and 1 renal cell cacinoma. Analysis of background cytologic features revealed that 77% of adenocacinoma cases showed benign mesenchymal components and hepatocytes and spuamous cell carcinoma cases disclosed benign mesenchymal tissue (71%) and necrosis (57%). Remaining cases showed variable combinations of benign mesenchymal component, necrosis, hepatocytes, and bile duct epithelial cells. No case revealed atypical hepatocytic naked nuclei, a useful cytologic finding of hepatocellular carcinoma. In summary, the background cytologic features more commonly observed in metastatic carcinomas than in the hepatocellular carcinoma were benign mesenchymal components, hepatocytes, necrosis, and bile duct epithelium. The endothelial cells and hepatocytic naked nuclei, two relatively specific findings of hepatocellular carcinoma were not observed except for renal cell carcinoma. Above background cytologic features are thought to be helpful for the differential diagnosis between the hepatocellular carcinoma and various metastatic carcinomas in the poorly differentiated cases.

Obesity is a serious worldwide health problem causing numerous obesity-related comorbidities such as hyperlipidemia, hypertension, diabetes, and cardiovascular dysfunctions. Recently, many studies indicate that obesity is strongly related with high rate of renal lesions and reducing weight with surgical intervention can improve renal parameters in obese patients, but the effect of bariatric surgery on obesity-induced chronic kidney disease (CKD) is hardly documented. This review study shows that bariatric surgery demonstrates beneficial reduction in proteinuria and albuminuria leading to improve both glomerular hyperfiltration and chronic kidney disease in obese population. Yet, bariatric surgery is not a definite treatment of choice for the obese patients with CKD because of lack of evidence explaining the risk of complications following bariatric surgery and clarification on estimating glomerular filtration rate (eGFR) in obese patients. Future, high quality studies with a long term follow up are required to determine the effective durability of bariatric surgery on obese-related CKD patients.

Carcinoid is a tumor that primarily affects the intestinal tract, which arises from entero-chromaffin cells. Rectal carcinoid tumor is a relatively rare neoplasm originated in Kul-chitszky cell and clinicians have the difficulties in predicting their malignant potential and in proper treatment. These cells are found to increase in the distal small intestine, are common in the appendix, and then decrease within the mucosa of the colon from cecum to rectum. In the cumulative world literature, the incidence of carcinoids of rectum is slightly higher than 10 percent. All of these tumors are within reach of the rigid procto-sigmoidoscope, most being located between 4 and 13 cm from the anal verge. Eighty five percent are found on the anterior and lateral walls. The tumors are usually submucosal and light yellowish or reddish color. The vast majority of rectal carcinoid tumors are be-nign, which can be treated by local excision safely. Lesions larger than 2 cm and invading the muscular wall of the rectum should be considered malignant, which are treated by more radical surgery such as abdominoperitoneal resection. We experienced a case of rectal carcinoid tumor, which was excised by endoscopic polypectomy, so we present this case with a review of relevant literatures.

PURPOSE: The purpose of this study was to identify effects of moving from a functional method of nursing care delivery to a modified team nursing delivery system. METHODS: A structured self-report questionnaire was used to measure satisfaction with the nursing delivery system, self-efficacy, job stress and nursing performance. Participants were 72 nurses working at a university hospital and data were collected three times; before, one month and three months after the modification to a modified team nursing delivery system. Data were analyzed using repeated measure ANOVA. RESULTS: Satisfaction with the nursing delivery system increased significantly after the change to the modified team nursing method. There were no significant differences in self-efficacy, job stress, or nursing performance. However, satisfaction with the nursing delivery system and nursing performance increased and job stress decreased significantly in new nurses with less than 1 year experience. CONCLUSION: Results indicate that a modified team nursing method has positive results on nurses' satisfaction, self-efficacy, job stress, and nursing performance compared to the functional method. Effect of changing the nursing delivery system in the hospital suggests possibilities and directions for a modified nursing delivery system that would be useful in hospitals presently using the functional method.
