AAC is estimated to represent at least 50% to 70% of all cases of acute cholecystitis during childhood. Although this pathology was originally described in critically ill or post-surgical patients, most pediatric cases have been observed during several infectious diseases. In addition to cases caused by bacterial and parasitic infections, most pediatric reports after 2000 described children developing AAC during viral illnesses(such as Epstein-Barr virus and hepatitis A virus infections). Moreover, some pediatric cases have been associated with several underlying chronic diseases and, in particular, with immune-mediated disorders. Here, we review the epidemiological aspects of pediatric AAC, and we discuss etiology, pathophysiology and clinical management, according to the cases reported in the medical literature.展开更多

We describe the diagnosis and treatment of a 43 year- old woman who presented with a persistent oral ulcer for approximately 1 year, and subsequent pain in the left posterior maxillary region. Clinical examination revealed an ulcer in the left upper molar gingiva, with swelling in the region from the second premolar to the third molar. X-ray images demonstrated the involvement of the maxillary alveolar bone. The histopathological and immunohistochemical features were diagnostic of ACC. ACC is often presented as a gingival lesion; thus, it may easily be neglected by patients. The identification of this tumor using specific pathological analyses prevents misdiagnosis and enables clinicians to determine the appropriate treatment. In this case, no recurrence or distant metastasis was observed after 2 years of follow-up.展开更多

She underwent partial nephrectomy after comprehensive evaluation, and she was finally diagnosed with renal myxoma according to pathological and immunohistochemical studies. Myxomas are rare, benign, soft-tissue tumors that mainly occur in the heart and skin, although various anatomical locations have been described. The kidneys are a rare location of myxoma; thus, renal myxomas may easily be misdiagnosed. To date, approximately 17 cases of renal myxoma have been reported in the English literature since 1968. All the patients in these cases underwent nephrectomy as treatment, and were disease-free on follow-up. Postoperative pathology facilitates a decisive diagnosis that differentiates benign from malignant myxoma, which is vital for the following treatment and prognosis.展开更多

Methods A total of 10 AIDS patients with malignant lymphoma seen in Beijing Ditan Hospital since 2009 were enrolled. Clinical manifestations, pathological examinations, immunity levels, Epstein-Barr virus antibody examinations, complications, treatments, and outcomes were retrospectively analyzed. Results The main clinical manifestations of these patients included intermittent fever in 2 cases, neck masses and fever in 3 cases, auxiliary lymph node enlargement in 2 cases, and abdominal pain and bloating with fever in 3 cases. Up to 7 patients were pathologically diagnosed with diffuse large B cell lymphoma （DLBCL）, and 3 patients were pathologically diagnosed with Burkitt＇s lymphoma. Up to 8 patients had CD4 cell counts below 200/μL, and 2 patients had a level of more than 200/μL. Up to 7 patients were negative for EBV-IgM antibodies and 3 patients were not examined. Six patients underwent different chemotherapy and their prognoses were different. One patient with Burkitt＇s lymphoma alternatively took CODOXM and IVAC for 3 turns after VP chemotherapy; 1 patient with liver metastasis took R-CHOP 5 times, then changed therapy regimen to R-MINE and MINE. One patient with adrenal DLBCL took CHOP 6 times. Three patients with DLBCL took CHOP 1 or 2 times. Four patients gave up treatment. Various infections and side effects occurred, including bone marrow suppression, gastrointestinal bleeding, and renal dysfunction during chemotherapy. Six patients took HAARI, and 4 did not. Six patients died, whereas 3 patients got improved; and 1 patient was discharged. Conclusions AIDS patients with malignant lymphoma had various clinical manifestations, were immunocompromised, and had multiple metastases when they were admitted; they were already in the interim or late stage of lymphoma. Chemotherapy was not effective, and additional complications occurred. HAART failed to improve patient prognosis, and the overall prognosis was poor.展开更多

Urine samples from the subjects were collected and examined in the laboratory using the Filteration technique for the detection and quantification ofSchistosoma haematobium eggs. The prevalence rate of urinary schistosomiasis at the Sunyani Regional Hospital for 2006, 2007, 2008 and 2009 were found to be 0.24%, 0.55%, 0.55% and 0.75% respectively while that for Methodist Junior High School in 2008 and 2009 were 60.1% and 60.3% respectively. A decrease in the relative humidity and average annual rainfall were identified as factors contributory to the increase in urinary schistosomiasis prevalence rate. The temperature values obtained throughout the study period did not have any significant effect on the prevalence rate. The temperature values, however, were those that enhanced cercarial incubation （15-35 ℃） with a resultant increase in shedding of cercariae leading to more infections among water contacts. The infection rate due to the stream Amama was 20.1%, while that due to river Tano was 36.6%. The highest risk group was children aged 15-19 years. Praziquantel was administered to treat the infection, producing a cure rate of 93%. Recognition of urinary schistosomiasis as a public health problem in Ghana is the main challenge to prevention and control of the disease.展开更多
