Peltophorum africanum (Fabaceae) is a deciduous tree widespread in southern Africa. The plant has many ethnomedical and ethnoveterinary uses. Root and bark decoctions are used to treat diarrhoea, dysentery, sore throat, wounds, back and joint pains, HIV-AIDS, venereal diseases and infertility. Pastoralists and rural farmers use the root and bark extracts to treat diarrhoea, dysentery, infertility, and to promote well-being and resistance to diseases in cattle. To evaluate these ethnobotanical leads, dried leaves, stem bark and root bark were extracted with ethanol, acetone, dichloromethane and hexane. Polyphenols in the extract were determined by the Folin-Ciocalteu method with gallic acid as standard. Qualitative antioxidant activity was screened by spraying thin layer chromatograms (TLC) of the extracts with 0.2% 1,1-diphenyl-2-picryl hydrazyl (DPPH), and quantified with Trolox equivalent antioxidant capacity (TEAC) assay. Minimum inhibitory concentration (MIC) and total antibacterial activity (TAA) were determined by serial microplate dilution for Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Enterococcus faecalis, with gentamicin as standard and tetrazolium violet as growth indicator. Acetone and ethanol extracted the largest quantity of material. Polyphenols concentration was 49.2% in acetone extract of the root and 3.8% in dichloromethane extract of the leaf. Antioxidant activity of at least 5 antioxidant compounds as measured by TEAC ranged from 1.34 (ethanol extract of the root) to 0.01 (hexane extract of the leaf). The total antibacterial activity (volume to which active compounds present in 1 g plant material can be diluted and still inhibit bacterial growth) was 1263 ml/g for ethanol extract of the root against S. aureus, and 800 ml/g for acetone extract of the root against P. aeruginosa. There was substantial activity against both Gram-positive and Gram-negative bacteria, with MIC values of 0.08 mg/ml for S. aureus and 0.16 mg/ml for P. aeruginosa. There is therefore a rationale for the traditional use of root and bark of P. africanum in treating bacterial infection related diseases.

Laboratory-based surveillance is a foundation for public health and is essential for determining the incidence of most foodborne diseases caused by bacterial pathogens; however, reported cases represent a subset of infections in the community. To identify the factors associated with seeking medical care and submitting a stool specimen among persons with acute diarrheal illness, we used multivariate logistic regression to analyze data from two 12- month population-based telephone surveys conducted in the Foodborne Diseases Active Surveillance Network (FoodNet) from 2000 to 2003. Of 31,082 persons interviewed, 5% reported an acute diarrheal illness in the four weeks prior to the interview; of these, 20% sought medical care. On multivariate analysis, among persons with an acute diarrheal illness, factors associated with seeking medical care included: male sex; age <5 or >or=65 years; household income <25,000 dollars; having health insurance; diarrhea duration >or=3 days; having bloody diarrhea, fever, vomiting, sore throat, or cough. Of those seeking medical care, 19% provided a stool sample. Bloody diarrhea (odds ratio [OR] 3.35; 95% confidence interval [CI] 1.18-9.51) and diarrhea duration >or=3 days (OR 3.81; 95% CI: 1.50-9.69) were the most important factors associated with submission of a stool specimen. Cases of acute diarrheal illness ascertained through laboratory-based public health surveillance are likely to differ systematically from unreported cases and likely over-represent those with bloody diarrhea and longer diarrhea duration.

Gambir (asen'yaku in Japanese), an aqueous extract of leaves and young twigs of Uncaria gambir Roxb., has traditionally been used as a treatment for diarrhea and dysentery as an internal medicine and for sore throat as a gargle. Although it is a pharmacopoeic medicine in Japan, the quantitative evaluation of its constituents has not yet been adopted in the Japanese pharmacopoeia. We analyzed polyphenolic constituents in 31 gambir and related products to establish evaluation methods, since gambir contains large amounts of polyphenolic constituents. The total flavan contents in the samples revealed using the vanillin-HCl estimation method ranged from 24-79%. Reversed-phase high performance liquid chromatography (RP-HPLC) analysis indicated that catechin was the most abundant constituent in each sample, with contents in the range of 7-76%. The catechin contents in the gambir products between the first and third quartiles were 28-54%. Thus, the lower limit of the catechin content in gambir products can be set at around 20% for quality management. Fifteen tested samples were subjected to HPLC analysis to show the presence of epicatechin (1.5% on average) and the dimeric compounds procyanidin B1, procyanidin B3, and gambiriin A1 (ca. 1% each). The molecular weight distributions of polymeric flavans in the gambir products were analyzed by gel permeation chromatography (GPC) and showed that the average degree of polymerization for each sample was 3 to 7. These results indicate that the combination of the vanillin-HCl method, RP-HPLC analysis, and GPC analysis gives valuable information for evaluating the polyphenolic profiles of gambir products.

Adenovirus serotypes 4 (ADV-4) and 7 (ADV-7) are important causes of febrile acute respiratory disease (ARD) in US military recruits. Previously licensed vaccines, which effectively controlled adenovirus-associated ARD, are no longer available. In the Fall of 2004 we conducted this Phase 1 randomized, double-blind, placebo-controlled trial of the live, oral ADV-4 and ADV-7 vaccines made by a new manufacturer to assess their safety and immunogenicity. The adenovirus vaccines were administered orally together in a single dose to thirty subjects. Twenty eight additional subjects received placebo. Subjects were then observed for 8 weeks. The most commonly reported adverse events were nasal congestion (33%), cough (33%), sore throat (27%), headache (20%), abdominal pain (17%), arthralgia (13%), nausea (13%) and diarrhea (13%). None of these rates differed significantly from placebo. The duration of vaccine virus fecal shedding was 7-21 days. Seventy three percent of vaccine recipients seroconverted to ADV-4 (GMT 23.3) while 63% seroconverted to ADV-7 (GMT 51.1) by Day 28. The new ADV-4 and ADV-7 vaccines were safe and induced a good immune response in the study population. Expanded trials for safety and efficacy are in progress.

A 54-year-old woman had an episode of sudden oral bleeding and generalized petechiae 1 week after a sore throat and diarrhea. On admission, the platelet count was 0.1 x 10(4)/microl, and the platelet-associated IgG level was elevated. Hyperplasia of megakaryocytes in a bone marrow specimen and aberrant Epstein-Barr virus (EBV) antibody patterns led to a diagnosis of EBV-associated idiopathic thrombocytopenic purpura (ITP). Prednisolone (PSL) promptly restored her platelet count; however, she developed disorientation and affective lability soon after PSL was tapered. Subsequently, she ran a high fever and developed convulsive seizures. T2-weighted MRI demonstrated a high signal area in the subcortical white matter, and no abnormal findings were found on examination of the cerebrospinal fluid. The diagnosis of acute disseminated encephalomyelitis (ADEM) was made and steroid pulse therapy was started, which resulted in remission of the symptoms without recurrence in the following months. This is the first reported case of ADEM following EBV infection during treatment for ITP. Administration of PSL for ITP might mask the presenting clinical picture of ADEM. The possibility of ADEM should be investigated in patients of ITP following viral infection who develop acute encephalopathy.

The biodiversity of medicinal plants in South Africa makes them rich sources of leading compounds for the development of novel drugs. Peltophorum africanum (Fabaceae) is a deciduous tree widespread in South Africa. The stem bark has been traditionally employed to treat diarrhoea, dysentery, sore throat, wounds, human immunodeficiency virus/ acquired immune deficiency syndrome (HIV/AIDS), venereal diseases and infertility. To evaluate these ethnobotanical clues and isolate lead compounds, butanol and ethyl acetate extracts of the stem bark were screened for their inhibitory activities against HIV-1 using MAGI CCR5+ cells, which are derived from HeLa cervical cancer cells and express HIV receptor CD4, a chemokine receptor CCR5 and HIV-LTR-beta- galactosidase. Bioassay-guided fractionation using silica gel chromatography was also conducted. The ethyl acetate and butanol extracts of the stem bark of Peltophorum africanum showed inhibitory activity against HIV-1, CXCR4 (X4) and CCR5 (R5) tropic viruses. The ethyl acetate and butanol extracts yielded previously reported anti-HIV compounds, (+)-catechin, a flavonoid, and bergenin, a C-galloylglycoside, respectively. Furthermore, we identified betulinic acid from the ethyl acetate fraction for the first time. The fractions, which contained betulinic acid, showed the highest selective index. We therefore describe the presence of betulinic acid, a not well-known anti-HIV compound, in an African medicinal herb, which has been used for therapy, and claim that betulinic acid is the predominant anti-HIV-1 constituent of Peltophorum africanum. These data suggest that betulinic acid and its analogues could be used as potential therapeutics for HIV-1 infection.

We describe a 32-year-old woman suspected of having pulmonary tuberculosis due to abnormal shadows found on her chest x-ray in a community health examination in September 2002. However, she consistently refused further examinations and treatment. In January 2005, she complained of a cough and sputum, by October she developed diarrhea, and by December a sore throat and fever. She was admitted to our hospital on January 23, 2006. Her chest radiograph revealed multiple thin-walled cystic lesions and infiltrative shadows in both upper lobes of the lung, a giant thin-walled cystic lesion in the superior segment of the left lower lobe, and diffuse particulate shadows. Since acid-fast staining of her sputum smear and a PCR test to detect tubercle bacilli both were positive, a diagnosis of pulmonary tuberculosis was made and we treated her with antituberculotic agents. Ten days after starting the treatment, her cystic lesions decreased or disappeared. Although she was seemingly healthy, her pulmonary tuberculosis became more severe since she failed to follow her treatment regimen. She therefore developed nutritional disorders and cellular immunity dysfunction that induced a sequence of changes, e.g. poor granuloma formation, excaration of caseous necrofic material by draining bronchi, and a check-valve mechanism. We speculate that these symptoms caused the formation of pneumatoceles. To our knowledge, this is the first case of pneumatocele formation found in a patient with pulmonary tuberculosis reported in Japan.

Common signs and symptoms of streptococcal pharyngitis include sore throat, temperature greater than 100.4 degrees F (38 degrees C), tonsillar exudates, and cervical adenopathy. Cough, coryza, and diarrhea are more common with viral pharyngitis. Available diagnostic tests include throat culture and rapid antigen detection testing. Throat culture is considered the diagnostic standard, although the sensitivity and specificity of rapid antigen detection testing have improved significantly. The modified Centor score can be used to help physicians decide which patients need no testing, throat culture/rapid antigen detection testing, or empiric antibiotic therapy. Penicillin (10 days of oral therapy or one injection of intramuscular benzathine penicillin) is the treatment of choice because of cost, narrow spectrum of activity, and effectiveness. Amoxicillin is equally effective and more palatable. Erythromycin and first-generation cephalosporins are options in patients with penicillin allergy. Increased group A beta-hemolytic streptococcus (GABHS) treatment failure with penicillin has been reported. Although current guidelines recommend first-generation cephalosporins for persons with penicillin allergy, some advocate the use of cephalosporins in all nonallergic patients because of better GABHS eradication and effectiveness against chronic GABHS carriage. Chronic GABHS colonization is common despite appropriate use of antibiotic therapy. Chronic carriers are at low risk of transmitting disease or developing invasive GABHS infections, and there is generally no need to treat carriers. Whether tonsillectomy or adenoidectomy decreases the incidence of GABHS pharyngitis is poorly understood. At this time, the benefits are too small to outweigh the associated costs and surgical risks.

In September 2008, the Austrian Agency for Health and Food Safety (AGES) learned of an outbreak of diarrheal illness that included a 71-year-old patient hospitalized for gastroenteritis with a blood culture positive for Listeria monocytogenes. Three stool specimens provided by seven of 19 persons attending a day trip to a foreign city, including a final break at an Austrian tavern, yielded L. monocytogenes. All isolates were of serovar 4b and had fingerprints indistinguishable from each other. A cohort study revealed that the outbreak of gastroenteritis occurred among 16 persons who had eaten dinner at the wine tavern on September 6. Of the 15 persons who ate from platters of mixed cold-cuts, 12 (80%) developed symptoms of febrile gastroenteritis within 24-48 h. The median age of those who became ill was 62 years. A 72-year-old patient recovered from gastroenteritis but was hospitalized with bacterial meningitis on day 19 after the dinner. The epidemiological investigation identified the consumption of mixed cold-cuts (including jellied pork) at the wine tavern as the most likely vehicle of the foodborne outbreak (P = 0.0015). This hypothesis was confirmed by microbiological investigation of jellied pork produced by the tavern owner on September 3. L. monocytogenes was isolated from leftover food in numbers of 3 x 10(3)-3 x 10(4) colony forming units/g and was indistinguishable from the clinical outbreak isolates. Symptoms reported by the 12 patients included unspecified fever (12x), diarrhea (9x), headache (5x), vomiting (4x), body aches (2x) and sore throat (1x). Active case finding identified one case of rhombencephalitis (female, age 48) among another group of four guests, among whom only the patient and her asymptomatic husband had eaten jellied pork on September 6. This is the first outbreak of L. monocytogenes-associated gastroenteritis reported in Austria. The occurrence of a secondary case of meningitis (diagnosed on day 19 after consumption of jellied pork) indicates a significant risk of systemic listeriosis among elderly patients with febrile gastroenteritis caused by L. monocytogenes; antibiotic therapy should therefore be considered in such cases of documented listerial gastroenteritis.

Antithyroid drugs are widely used to treat hyperthyroidism, especially Graves' disease, but they tend to cause agranulocytosis, which increases the mortality rate. Granulocyte colony-stimulating factor decreases the duration of recovery from agranulocytosis. We retrospectively studied cases of antithyroid drug-induced agranulocytosis over the past 10 years in a northern Taiwan medical center. A clinical evaluation was conducted, including a review of complete blood cell counts and differential counts. Four cases were included in this analysis. Agranulocytosis persisted in 2 cases despite a change in therapy from propylthiouracil to methimazole. Fever, sore throat, and diarrhea were common symptoms of agranulocytosis. Initial white blood cell counts ranged from 450 to 1,710/microL. Only 1 case had a positive result from a throat swab culture (Staphylococcus aureus). Three of 4 cases received granulocyte colony-stimulating factor therapy, and the recovery time ranged from 3 to 13 days. All of the patients recovered from agranulocytosis. We concluded that: (1) conducting a routine complete blood cell count is beneficial in alerting caregivers to the possibility of agranulocytosis; (2) educating patients about the common symptoms of agranulocytosis may contribute to an early diagnosis; (3) providing granulocyte colony-stimulating factor therapy to patients results in good prognosis; and (4) monitoring for cross-reactions between drugs should be performed to prevent further episodes of agranulocytosis.
