Histological Examination in Obtaining a Diagnosis in Patients with Lymphadenopathy in Lima, Peru.
The differential diagnosis for lymphadenopathy is wide and clinical presentations overlap, making obtaining an accurate diagnosis challenging. We sought to characterize the clinical and radiological characteristics, histological findings, and diagnoses for a cohort of patients with lymphadenopathy of unknown etiology. 121 Peruvian adults with lymphadenopathy underwent lymph node biopsy for microbiological and histopathological evaluation. Mean patient age was 41 years (Interquartile Range 26-52), 56% were males, and 39% were HIV positive. Patients reported fever (31%), weight loss (23%), and headache (22%); HIV infection was associated with fever (P < 0.05) and gastrointestinal symptoms (P < 0.05). Abnormalities were reported in 40% of chest X-rays (N = 101). Physicians suspected TB in 92 patients (76%), lymphoma in 19 patients (16%), and other malignancy in seven patients (5.8%). Histological diagnoses (N = 117) included tuberculosis (34%), hyperplasia (27%), lymphoma (13%), and nonlymphoma malignancy (14%). Hyperplasia was more common (P < 0.001) and lymphoma less common (P = 0.005) among HIV-positive than HIV-negative patients. There was a trend toward reduced frequency of caseous necrosis in samples from HIV-positive than HIV-negative TB patients (67 versus 93%, P = 0.055). The spectrum of diagnoses was broad, and clinical and radiological features correlated poorly with diagnosis. On the basis of clinical features, physicians over-diagnosed TB, and under-diagnosed malignancy. Although this may not be inappropriate in resource-limited settings where TB is the most frequent easily treatable cause of lymphadenopathy, diagnostic delays can be detrimental to patients with malignancy. It is important that patients with lymphadenopathy undergo a full diagnostic work-up including sampling for histological evaluation to obtain an accurate diagnosis
Clinical Deterioration during Antitubercular Treatment at a District Hospital in South Africa: The Importance of Drug Resistance and AIDS Defining Illnesses
Background: Clinical deterioration on drug therapy for tuberculosis is a common cause of hospital admission in Africa. Potential causes for clinical deterioration in settings of high HIV-1 prevalence include drug resistant Mycobacterium tuberculosis (M.tb), co-morbid illnesses, poor adherence to therapy, tuberculosis associated-immune reconstitution inflammatory syndrome (TB-IRIS) and subtherapeutic antitubercular drug levels. It is important to derive a rapid diagnostic work-up to determine the cause of clinical deterioration as well as specific management to prevent further clinical deterioration and death. We undertook this study among tuberculosis (TB) patients referred to an adult district level hospital situated in a high HIV-1 prevalence setting to determine the frequency, reasons and outcome for such clinical deterioration. Method: A prospective observational study conducted during the first quarter of 2007. We defined clinical deterioration as clinical worsening or failure to stabilise after 14 or more days of antitubercular treatment, resulting in hospital referral. We collected data on tuberculosis diagnosis and treatment, HIV-1 status and antiretroviral treatment, and investigated reasons for clinical deterioration as well as outcome. Results: During this period, 352 TB patients met inclusion criteria; 296 were admitted to hospital accounting for 17% of total medical admissions (n = 1755). Eighty three percent of TB patients (291/352) were known to be HIV-1 co-infected with a median CD4 count of 89cells/mm3 (IQR 38-157). Mortality among TB patients admitted to hospital was 16% (n = 48). The median duration of hospital admission was 9.5 days (IQR 4-18), longer than routine in this setting (4 days). Among patients in whom HIV-1 status was known (n = 324), 72% of TB patients (n = 232) had an additional illness to tuberculosis; new AIDS defining illnesses (n = 80) were the most frequent additional illnesses (n = 208) in HIV-1 co-infected patients (n = 291). Rifampin-resistant M.tb (n = 41), TB-IRIS (n = 51) and drug resistant bacterial infections (n = 12) were found in 12%, 14% and 3.4% of the 352 cases, respectively. Interpretation: In our setting, new AIDS defining illnesses, drug resistant M.tb and other drug resistant bacteria are important reasons for clinical deterioration in HIV-1 co-infected patients receiving antitubercular treatment. HIV-1 coinfected patients may be at increased risk of acquiring nosocomial drug resistant pathogens because profound immune suppression results in co-morbid illnesses that require prolonged inpatient admissions. Routine infection control is essential and needs to be strengthened in our setting. Copyright: © 2009 Pepper et al
Trichinellosis acquired in the United Kingdom.
An outbreak of trichinellosis that occurred in the United Kingdom is described. Members of four households consumed pork salami from northern Serbia, the Federal Republic of Yugoslavia. Eight cases of trichinellosis occurred. Clinical and laboratory features of the cases were typical with myalgia (7 cases), fever (6), headache (5), periorbital oedema (4), non-specific ST/T wave changes on electrocardiogram (3), Trichinella antibodies (6), eosinophilia (7) and raised serum creatine kinase (3). All recovered. Trichinella larvae were detected in the salami. During pre-travel counselling, travellers should be advised about possible risk from cured pork products which have been produced locally in Trichinella endemic areas

Antimalarial Potential Study of Cucumber Skin and Base Point Chloroform Extract as A Solution to Organic Waste of Sidewalk Food Stall Treatment in YOGYAKARTA
Malaria is a major infectious disease in the world. The disease is caused by blood protozoan from the genus Plasmodium. The main problem in controling this disease is resistance parasite cases to drugs that have been used. Cucumber (Cucumis sativa L.) contain bioactive compounds suspected of terpenoids and saponins are believed to reduce the level of parasitemia. Waste of skin and cucumber base is very abundant, especially from stalls in the city of Yogyakarta. Estimated at the base and cucumber skin there are bioactive content that can be used as an alternative antimalarial drug. This research aims to study the potential of chloroform extract and the base of the fruit peel waste to the level of parasitemia of Plasmodium berghei in mice. First step is collecting the waste of skin and cucumber base in some stalls in the city of Yogyakarta. Extraction by maceration method using chloroform solvent, the method further phytochemical studies by Thin Layer Chromatography (TLC). Antiplasmodium test with negative control treatment (DMSO 0.3%), positive control (chloroquine 3 mg / kg), the dose C.sativa extract 100; 200; 300; 400 and 500 mg / kg in male mice given strain Switzerland 3 months of age infected with Plasmodium berghei orally. T he results showed there were terpenoids and saponins compounds in the chloroform extracts of C.sativa base and skin. The most effective dose of the extract inhibition of parasitemia level P. berghei in mice treated P5 is the highest (500 mg / kg BB), which is still higher than the standard drug Chloroquine so that waste of skin and the base C.sativa potential as an alternative antimalarial drug
High Dietary Taurine Reduces Apoptosis and Atherosclerosis in the Left Main Coronary Artery
We sought to determine whether taurine could specifically protect against coronary artery disease during an
atherogenic diet and whether taurine affects the lipid profile, metabolites of methionine, and endothelial atherogenic
systems. Rabbits were fed one of the following diets for 4 weeks: (1) control diet; (2) 0.5% cholesterol+1.0%
methionine; or (3) 0.5% cholesterol+1.0% methionine+2.5% taurine. Endothelial function was examined, and the left
main coronary artery atherosclerosis was quantified by stereology and semiquantitative immunohistochemistry to
determine the endothelial expression of proteins related to the NO, renin-angiotensin, endoplasmic reticulum, and
oxidative stress systems, as well as apoptosis. Taurine normalized hyperhomocysteinemia (P<0.05) and significantly
reduced hypermethioninemia (P<0.05) but not lipidemia. The intima:media ratio was reduced by 28% (P=0.034), and
atherosclerosis was reduced by 64% (P=0.012) and endothelial cell apoptosis by 30% (P<0.01). Endothelial cell
CCAAT/enhancer binding protein homologous protein was normalized (P<0.05). Taurine failed to improve hyperlipidemia,
endothelial function, or endothelial proteins related to the NO, renin-angiotensin, and oxidative stress systems.
Taurine reduces left main coronary artery wall pathology associated with decreased plasma total homocysteine,
methionine, apoptosis, and normalization of CCAAT/enhancer binding protein homologous protein. These results
elucidate the antiapoptotic and antiatherogenic properties of taurine, possibly via normalization of endoplasmic
reticulum stress
