Psoas abscess (PA) is an infrequent clinical entity and presents diagnostic and therapeutic challenges. Six cases are reported concerning diagnostic and therapeutic considerations. Clinical diagnosis is difficult because of non-specific symptoms. The primary psoas abscess has no definite etiology and is spread by hematogeneous route from a distant occult site. The PA can also be secondary to gastrointestinal pathology through direct infection of adjacent structures. The most common causes are Crohn's disease, appendicitis, diverticulitis and carcinoma. Routine laboratory evaluation is seldom useful for localizing the disease process. Conventional radiological techniques are often unhelpful. Modern imaging diagnosis techniques such as ultrasound and computerized tomography have allowed for a refinement in both the etiologic diagnosis and the treatment by means of CT-guided or ultrasound-guided percutaneous drainage of the abscess, thus avoiding surgical drainage in many cases. Immediately on diagnosis of PA prompt treatment is necessary. Percutaneous drainage should be performed whenever possible and in case of failure, surgical drainage should be practiced as well as intestinal resection, whenever indicated. 相似文献

Cystic Fibrosis (CF) results from mutation in the transmembrane conductance regulator gene, responsible for controlling secretory processes. The upper airways (UA) are usually involved in the form of chronic pansinusitis.ObjectiveTo evaluate UA changes in patients with CF and to establish the correlations between sinonasal CT and endoscopic endonasal findings and disease severity.MethodCross-sectional and prospective study with 20 patients older than 5 years with CF, assessing the Shwachman-Kulczycki (S-K) score, paranasal sinus tomography (CT) (Lund-Mackay score) and nasal endoscopy (Meltzer score).ResultsCT scan alterations were observed in 94% of cases. Endoscopic alterations findings in the upper airways were found in 10 patients. Nasal polyps were found in 3 patients (15%). There was a correlation between the intensity of changes on the CT and S-K score (p = 0.0097), and between endoscopic findings and S-K score (p = 0.0318). There was a positive correlation between the presence of chronic colonization and endoscopic findings (p = 0.0325), which was not observed on the CT (p = 0.2941).ConclusionThere is an inverse correlation between the S-K clinical score and nasal endoscopy and CT findings. Therefore, patients who are clinically more severe according to the S-K score have greater UA involvement. 相似文献

In patients with Mansoni schistosomiasis, it is fundamental to evaluate the disease morbidity, which is reflected by the severity of periportal fibrosis (PPF) and parameters of portal hypertension, as analyzed by ultrasonography (US). This study aimed to evaluate the morbidity of schistosomiasis by hepatic and splenic point shear-wave elastography (pSWE) and relate this to US parameters. The PPF pattern, the diameter of the portal and splenic veins and the size of the spleen were evaluated by US. Then, liver and spleen pSWEs were assessed in 74 patients using the same equipment. As the PPF pattern progressed, the splenic pSWE values significantly increased. Significant correlations between splenic pSWE, the longitudinal and transverse lengths of the spleen and the diameters of the portal and splenic veins were observed. These findings, however, were not observed through hepatic pSWE. In conclusion, the splenic pSWE has the potential for assessing morbidity in schistosomiasis mansoni. 相似文献

The development of new biomarkers for the diagnosis and prognosis of ovarian cancer may provide an opportunity for new therapies. In this study, we aimed to compare cytokines (interleukin [IL]‐2, IL‐5, IL‐6, IL‐8, IL‐10 and tumour necrosis factor [TNF]‐α) and nitric oxide (NO) metabolite levels in non‐neoplastic tumours, benign primary ovarian tumours and malignant primary ovarian neoplasms. The secondary aim was to relate cytokine and intracystic NO metabolite levels to clinical, laboratory and pathologic characteristics for patients with primary ovarian malignancies. We evaluated 110 patients with adnexal masses. Cytokine concentrations were quantified by enzyme‐linked immunosorbent assay and nitrate concentrations by enzymatic reduction of nitrite by nitrate reductase. Patients with malignant neoplasms had higher IL‐6, IL‐8 and NO levels compared to patients with benign neoplasms. Histologic grade 1 tumours were associated with elevated IL‐2 levels, whereas anaemia was associated with elevated IL‐6 levels. On average, those patients with elevated IL‐8 levels also had a neutrophil/lymphocyte ratio (NLR) greater than 2.6 and less than 36 months of disease‐free survival (DFS). Patients with normal CA 19‐9 levels had elevated IL‐10 levels. TNF‐α was elevated in patients with two carcinogenesis and those with a platelet/lymphocyte ratio (PLR) less than 300. NO levels were higher in patients with an NLR less than 2.6 and CA 19‐9 greater than 35 U/ml. Elevated intracystic cytokine levels, especially IL‐6 and IL‐8, are associated with worse prognosis in ovarian cancer. 相似文献

Ewing sarcoma is a primitive neuroectodermal tumor rarely occurs in the skin and
sobcutaneous tissues. Generally Ewing''s sarcoma is a primary bone tumor, but
when present in soft tissues it characterizes an extremely uncommon clinical
picture. It usually involves the deep subcutaneous tissue or muscles, and more
rarely occurs like a primary skin cancer. Most patients are white, women, and in
the second decade of life. The clinical features are a superficial mass, in
average measuring 2-3 cm, of soft consistency, freely mobile and sometimes
painful. The more affected locations are upper and lower extremities, trunk,
head, neck or multiple lesions. The presence of metastases is very rare. 相似文献
