Hepatic involvement of disseminated actinomycosis

A 35-year-old woman was admitted for weight loss, fatigue, and epigastric and back pain. She had undergone uterine myomectomy 6 weeks previously, and light microscopic examination revealed actinomycosis. Radiologic examination showed 5×4×4 cm and 2×2×2 cm solid lesions in the left liver lobe. Ultrasound-guided fine-needle aspiration biopsy could not exclude the possibility of malignancy. We decided to perform an explorative laparotomy. Frozen sections indicatedEchinococcus alveolaris infection or granulomatous inflammatory disease, and left hepatic lobectomy was performed. Histologic examination revealed hepatic actinomycosis. After 6 months' penicillin treatment, there was no sign of recurrence. This case of hepatic actinomycosis following uterine infection without gross involvement of any other abdominal organ raises questions on the dissemination pathway. The other interesting feature of this case is the short interval from the presumed initiatory event to the presence of the hepatic deposits.     

The spectrum of diseases causing fever of unknown origin in Turkey: a multicenter study.

OBJECTIVE: The purpose of this trial was to determine the spectrum of diseases with fever of unknown origin (FUO) in Turkey. METHODS: A prospective multicenter study of 154 patients with FUO in twelve Turkish tertiary-care hospitals was conducted. RESULTS: The mean age of the patients was 42+/-17 years (range 17-75). Fifty-three (34.4%) had infectious diseases (ID), 47 (30.5%) had non-infectious inflammatory diseases (NIID), 22 (14.3%) had malignant diseases (MD), and eight (5.2%) had miscellaneous diseases (Mi). In 24 (15.6%) of the cases, the reason for high fever could not be determined despite intensive efforts. The most common ID etiologies were tuberculosis (13.6%) and cytomegalovirus (CMV) infection (3.2%). Adult Still's disease was the most common NIID (13.6%) and hematological malignancy was the most common MD (7.8%). In patients with NIID, the mean duration of reaching a definite diagnosis (37+/-23 days) was significantly longer compared to the patients with ID (25+/-12 days) (p=0.007). In patients with MD, the mean duration of fever (51+/-35 days) was longer compared to patients with ID (37+/-38 days) (p=0.052). CONCLUSIONS: Although infection remains the most common cause of FUO, with the highest percentage for tuberculosis, non-infectious etiologies seem to have increased when compared with previous studies.     

Obesity and cardiometabolic disease risk factors among US adolescents with disabilities

AIM: To generate prevalence estimates of weight status and cardiometabolic disease risk factors among adolescents with and without disabilities.METHODS: Analysis of the 1999-2010 National Health and Nutrition Examination Survey data was conducted among 12-18 years old with(n = 256) and without disabilities(n = 5020). Mean values of waist circumference, fasting glucose, high-density-lipoprotein cholesterol, triglycerides, systolic and diastolic blood pressure and metabolic syndrome(Met S, ≥ 3 risk factors present) were examined by the following standardized body mass index(BMI) categories for those with and without disabilities; overweight(BMI ≥ 85th- 95 th percentile for age and sex), obesity(BMI ≥ 95 th percentile) and severe obesity(BMI ≥35 kg/m2). Linear regression models were fit with each cardiometabolic disease risk factor independently as continuous outcomes to show relationships with disability status. RESULTS: Adolescents with disabilities were significantlymore likely to be overweight(49.3%), obese(27.6%) and severely obese(12%) vs their peers without disabilities(33.1%, 17.5% and 3.6%, respectively, P ≤ 0.01 for all). A higher proportion of overweight, obese and severely obese children with disabilities had abnormal SBP, fasting lipids and glucose as well as Met S(18.9% of overweight, 32.3% of obese, 55% of severely obese) vs their peers without disabilities(9.7%, 16.8%, 36.3%, respectively). US adolescents with disabilities are over three times as likely to have Met S(OR = 3.45, 95%CI: 1.08-10.99, P = 0.03) vs their peers with no disabilities.CONCLUSION: Results show that adolescents with disabilities are disproportionately affected by obesity and poor cardiometabolic health vs their peers with no disabilities. Health care professionals should monitor the cardiometabolic health of adolescents with disabilities.     

Poststreptococcal reactive arthritis in children: is it really a different entity from rheumatic fever?

Poststreptococcal reactive arthritis (PSRA) is an acute, nonsuppurative arthritis following documented streptococcal infections. Although most authors accepted it as a different entity, the differences from acute rheumatic fever (ARF) are not clear. To document and compare the clinical and laboratory characteristics of PSRA and ARF, 24 patients with PSRA and 20 with ARF were enrolled in the study. The latency period from upper respiratory tract infection was shorter in patients with PSRA ( P<0.01). However, 25% of the patients with ARF had also short (<10 days) latency periods. Although symmetric and nonmigratory arthritis were more frequent in patients with PSRA, there was no significant difference for the distribution of mono-, oligo-, and polyarticular disease between PSRA and ARF patients. The frequency of small joint and hip involvement was also similar between the patient groups. Unresponsiveness of articular symptoms to salicylate therapy within 72 h was more frequent in patients with PSRA (P<0.001). However, in a substantial part of the patients with ARF (nine patients, 45%), joint symptoms also had no response during the first 72 h. Since there is a considerable overlap of symptoms, signs, and laboratory features of PSRA and ARF, a line between these two entities could not be easily drawn. We conclude that these two conditions are actually different presentations of the same disease.     

The role of gender in patients with diffuse large B cell lymphoma treated with rituximab-containing regimens: a meta-analysis

Introduction

Diffuse large B cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma (NHL). Although gender has not been included in prognostic systems, male gender has been found as a bad prognostic indicator in Hodgkin lymphoma, follicular lymphoma and chronic lymphocytic leukemia. The relationship between gender and prognosis is not clear in patients with DLBCL treated with rituximab-containing regimens. The aim of this meta-analysis is to determine the prognostic/predictive role of gender in patients with DLBCL treated with rituximab-containing regimens.

Material and methods

We systematically searched for studies investigating the relationships between gender and prognosis in DLBCL treated with rituximab-containing regimens. After careful review, survival data were extracted from eligible studies. A meta-analysis was performed to generate combined hazard ratios for overall survival, disease-free survival (DFS) and event-free survival (EFS).

Results

A total of 5635 patients from 20 studies were included in the analysis. Our results showed that male gender was associated with poor prognosis in terms of overall survival (OS) (hazard ratio (HR) = 1.155; 95% confidence interval (CI): 1.037–1.286; p < 0.009). The pooled hazard ratio for DFS and EFS showed that male gender was not statistically significant (HR = 1.219; 95% CI: 0.782–1.899; p = 0.382, HR = 0.809; 95% CI: 0.577–1.133; p = 0.217).

Conclusions

The present meta-analysis indicated male gender to be associated with a poor prognosis in patients with DLBCL treated with rituximab-containing regimens.
