RESUMO

Bedside lung ultrasonography (LUS) is a reliable method for the diagnosis of pneumonia. No common consensus exists in the literature regarding the effectiveness of LUS findings, except consolidation, for the diagnosis of pneumonia. The primary objective of this study was to investigate the effectiveness of LUS for the diagnosis of pneumonia, and the secondary objective was to investigate the use of LUS findings, except consolidation, for the diagnosis of pneumonia. A total of 127 patients with clinically suspected pneumonia were evaluated in the study. The sensitivity and specificity of LUS were 98.0% and 95.8%, respectively. In the cases where consolidation was not determined in LUS but B-3 line positivity or a diffuse interstitial pattern was present, the sensitivity and specificity were 93.3% and 88.2%, respectively. When consolidation was not observed in LUS, the presence of B-3 line positivity or diffuse interstitial pattern could be used for the diagnosis of pneumonia.

RESUMO

PURPOSE: Trauma is the most common cause of death of young people in the world. As known, mesenchymal stem cells (MSCs) accelerate tissue regeneration mechanisms. In our study, we aimed to investigate the effects of MSCs transplantation on the healing of liver and bone tissue by considering trauma secondary inflammatory responses. METHODS: 56 adult Wistar-albino rats were divided into two groups: the polytrauma (liver and bone) (n = 28), and the liver trauma group (n = 28). At 36 h and 5th day after surgery, both rats with polytrauma and with isolated liver injury received either intravenous (IV) or intraperitoneal (IP) injections of MSCs (one million cells per kg body weight). Untreated groups received IV and IP saline injections. At day 21 after surgery, liver, tibia and fibula of the subjects were excised and evaluated for histopathologic and histomorphometric examination. Additionally, whole blood count (white blood cells, hemoglobin and platelets), C-reactive protein (CRP), glucose, alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, blood gas, and trauma markers interleukin-1B (IL-1B), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF alpha) levels were investigated. RESULTS: In general, MSC transplantations were well tolerated by the subjects. It was found that ALT, CRP, albumin were significantly lower in rats which received MSCs (p < 0.001). Inflammation of the liver and bone tissue in the MSC-injected rats were significantly lower than that of the untreated groups. CONCLUSIONS: Herewith we have shown that MSC infusion in posttraumatic rats leads to less aggressive and more effective consequences on liver and bone tissue healing. Human MSC treatment for trauma is still in early stages of development; thus standard protocols, and patient inclusion criteria should be established beforehand clinical trials.

RESUMO

INTRODUCTION: Acute cholecystitis is one of the most common reasons of acute abdominal pain for older patients to present to the emergency department (ED). Presentation may differ from that of the younger patient and is often complicated by coexistent disease due to elderliness. In this study, we aimed to evaluate the clinical presentation of acute cholecystitis, with special focus on comparision between elderly and young patients. MATERIALS AND METHODS: This study included 318 patients who were admitted to the emergency department with right upper quadrant pain during a period of determined 8 months. After retrospective data collection, patients were groupped in accordance with their age, <65 and ≥65 years. Those who had ultrasonographic signs such as wall thickening and fluid collection were diagnosed as acute cholecystitis. RESULTS: The young group (Group I) consisted of 225 patients, 132 females and 93 males. In Group I, 39 patients were diagnosed as acute cholecystitis of whom 27 were females and 15 were males. The elderly group (Group II) consisted of 93 patients 48 females and 45 males. In Group II, 36 patients were diagnosed as acute cholecystitis of whom 15 were females and 21 were males. Regarding the diagnosis of acute cholecystitis, the female to male ratio is 2.25 in Group I and 0.71 in Group II (p=0.016). The average white blood cells counts of patients with acute cholecystitis in Group I and in Group II were 9907x109/L(±4.437) and 17083x109/L(±7485), respectively (p<0,001). CONCLUSIONS: Acute cholecystitis is a common diagnosis in elderly patients with right upper quadrant pain. It is more frequent in female in the early ages, but the gender difference tends to change with age. Elderly patients demonstrate a higher level of white blood cells when compared to young patients in acute cholecystitis. Clinicians must maintain a degree of awareness in the evaluation of geriatric patients with right upper quadrant abdominal pain.
