Bidens pilosa is an annual plant from tropical America with anti-inflammatory properties in hepatitis, laryngitis, headache and digestive disorders, among others. Its wide pharmacological applications can be attributed to its chemical composition, with inhibitory effects on pathogenic microorganisms and flavonoids, which show strong antioxidant capacities. We investigated the antioxidant activity of an aqueous infusion of Bidens pilosa by studying its protective effect on the hemolysis induced by an initiator of radicals such as 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH). The immunomodulatory activity of the infusion was tested using whole blood cells. Cytokine production increased in whole blood stimulated or not by lipopolysaccharides (LPSs). The infusion is also characterized by its capacity to protect erythrocytes from the phototoxic effect of chlorpromazine, which allows its use as a potential photoprotector. Finally, it did not show ocular irritation, as demonstrated by the effect on hemoglobin denaturation. This study supports the health benefits of the ingestion of the infusion.

Chronic meningococcaemia is a very rare clinical manifestation of invasive infection by Neisseria meningitidis. A 9-year-old girl was admitted to our clinic with complaints of fever, headache, arthralgia, and maculopapular rash. The diagnosis was made by the growth of Neisseria meningitidis in the blood cultures. Four days after admission, liver function tests were increased and were compatible with cholestatic hepatitis. Thereafter, the patient was successfully treated and symptoms were completely resolved. To our knowledge, there have been no previous reports of Neisseria meningitidis causing cholestatic hepatitis. Herein, we present an unusual child patient with chronic meningococcaemia associated with cholestatic hepatitis.

Human immunodeficiency virus type 1 (HIV-1) infection has a broad spectrum of clinical manifestations, ranging from asymptomatic seroconversion to a severe symptomatic illness resembling infectious mononucleosis or other medical conditions including hepatitis, meningoencephalitis, or pneumonitis. Without clinical alertness, the illness is usually misdiagnosed or even not considered. Here we report 3 cases of acute HIV-1 infection with either a negative HIV-1 antibody assay or an indeterminate Western blot result, but high plasma levels of HIV-1 RNA. The initial presentations included fever, skin rash, sore throat, neck lymphadenopathy, cough and headache. One patient presented with infectious mononucleosis-like illness, 1 with aseptic meningitis, and 1 with acute tonsillitis. Physicians should be alert to the possibility of acute HIV-1 infection, especially in cases with unexplained fever, lymphadenopathy or rash.

We retrospectively reviewed 34 consecutive patients with serologically confirmed leptospirosis admitted during years 1992-2002. Nine patients (26.5%) had respiratory symptoms on admission including cough (n = 4), shortness of breath (n = 4), cyanosis (n = 2), and hemoptysis (n = 1). Six patients had pulmonary radiographic findings including (1) diffuse, ill-defined, ground-glass density (n = 3); (2) diffuse alveolar opacities (n = 2); and (3) small nodular density (n = 1). Male/female ratio was 8/1 and mean age was 47 years. Seven patients reported their exposure source including hunting (n = 2), fishing (n = 2), fresh water swimming (n = 2), and canoeing (n = 1). All patients had fever (mean = 40.1 degrees C). Other common symptoms were headache (n = 4), vomiting (n = 3), and myalgia (n = 3). Biological abnormalities included elevated liver enzymes (n = 8), proteinuria (n = 7), lymphopenia (n = 6), hematuria (n = 5), renal failure (n = 4), anemia (n = 4), and elevated neutrophil count (n = 4). PaO(2 )was measured for 3 patients while they were breathing room air (32, 55, and 66 mmHg). Suspected diagnosis on admission included leptospirosis (n = 2), bacterial pneumonia (n = 2), intoxication, influenza, viral hepatitis, biliary tract lithiasis, and rapidly progressive glomerulonephritis (one patient each). The first serologic testing for leptospirosis was positive for 5 patients (55%). Serovar was presumptively identified for 7 patients: Australis (n = 3), Grippotyphosa (n = 2), and Icterohaemorrhagiae (n = 2). Seven patients were treated with penicillin; two patients received no antibiotics. All patients were cured. In conclusion, patients with leptospirosis may present predominantly with nonspecific pulmonary symptoms. In these patients, leptospirosis must be suspected when there is a potential exposure to rats, especially in case of high-grade fever, myalgia, hepatitis, and renal abnormalities.

Acute urticaria is commonly observed in the prodromic stage of hepatitis A and B infection as well as in hepatitis C infection, although only rare cases have been published regarding the latter. Urticaria is considered one of the pre-icteric symptoms of viral hepatitis and is related to immune-complex deposits; subsequently, it may be associated with arthritis and headache (Caroli's triad). The absence of specific presentation of acute urticaria in patients with viral hepatitis is not surprising because many other viral infections can induce similar cutaneous symptoms. On the other hand, no convincing evidence exists in which hepatitis virus infection caused chronic urticaria. Data are lacking for hepatitis B, but several series and one controlled study showed the absence of a link between hepatitis C and chronic urticaria. Systematic hepatitis virus investigations in patients with chronic urticaria probably are not cost-effective. Hepatitis B or C can occasionally induce urticarial vasculitis, but this is probably related more to vasculitis than to true urticaria.

Efalizumab is a recombinant humanised IgG1 kappa isotype monoclonal antibody against the CD11a molecule. Efalizumab is approved for the treatment of moderate-to-severe psoriasis and is currently administered as a weekly subcutaneous injection. Throughout October 2005, 19,000 patients were treated with efalizumab. According to the package insert that is based on 2762 subjects, the most common adverse reactions associated with efalizumab are a first dose reaction complex that includes headache, chills, fever, nausea and myalgia within two days following the first two injections. These reactions are dose-level-related in incidence and severity and were largely mild-to-moderate in severity when a conditioning dose of 0.7 mg/kg was used as the first dose. Adverse events occurring at a rate between 1 and 2% greater in the efalizumab group compared with placebo were arthralgia, asthenia, peripheral oedema and psoriasis. Efalizumab is associated with a rebound flare reaction in approximately 5% of patients when therapy is ceased. Antiefalizumab antibodies develop in approximately 5% of the subjects who were treated with efalizumab, but the clinical significance of these antibodies is unclear. Efalizumab has rare but serious haematological side effects. Immune-mediated thrombocytopenia platelet counts at or below 52,000 cells/microl have been observed in 0.3% of cases and monitoring of platelet counts monthly for the first 3 months of use and each 3 months thereafter. Reports of four cases of haemolytic anaemia diagnosed four to six months after patients started on the monoclonal antibody exist. Infrequent new onset or recurrent severe arthritis events, including psoriatic arthritis events, have been reported in clinical trials and postmarketing surveillance. Symptoms associated with a hypersensitivity reaction (e.g., dyspnoea, asthma, urticaria, angioedema, maculopapular rash) were rarely noted in the first 12 weeks of the controlled clinical studies. The overall incidence of malignancies of any kind was 1.8 per 100 patient-years for efalizumab-treated patients compared with 1.6 per 100 patient-years for placebo-treated patients. One case each of the following serious adverse reactions was observed: transverse myelitis, bronchiolitis obliterans, aseptic meningitis, idiopathic hepatitis, sialedenitis and sensorineural hearing loss. In the complete safety data from both controlled and uncontrolled studies, the overall incidence of hospitalis ation for infections was 1.6 per 100 patient-years for efalizumab-treated patients compared with 1.2 per 100 patient-years for placebo-treated patients. The rate of infection was 26% in the control group and 29% in treated cases. The most common findings on laboratory assessments in patients using efalizumab were reversible increases in lymphocyte count and total white blood cell. Efalizumab is a safe, effective, but expensive treatment for psoriasis.

Clinical and laboratory features, complications and treatment were retrospectively studied in 70 patients with bacteriologically documented typhoid fever, treated between January 1995 and June 2002 at Principal Hospital in Dakar, Senegal. Data analysis was done on a global basis as well as comparatively between the 37 children (under 15 years) and 33 adults. Mean age was 16.7 years (range, 1 to 52). The sex ratio was 1.4. Clinical manifestations included fever (97%), headache (50%), vomiting (71%), abdominal pain (54%), diarrhoea (49%), nnd splenomegaly (10%) without statistically significant difference between children and adults. Lyinphopenia was found in 51% of patients and anaemia in 78%. Coexisting illnesses Included malaria in 25.5% (mainly children) and hepatitis (transminases > 10N) in 24%. Complications included cholecystitis in 3 patients, gastrointestinal haemorrhage in 2, peritonitis in one, endocnrditis in one and osteomyelitis in one. Only one patient (HIV-positive) died. The incidence of antibiotic resistance was low, i.e., ainoxicilline: 2%, nalidixic acid: 1% and cotrimoxazole: 8.2%. No multidrug resistance was observed. This study shows that typhoid fever remains a major health problem in Dakar with slow resolution and potential complications. Amoxicililne and chloramphenicol can still be used for first-line treatment of typhoid fever. Little difference was found between children and adults.

Two hundred and twenty seven patients were included in the study. The test group included 55 patients of pyrexia of unknown origin (PUO), 42 veterinary workers, 38 hepatitis patients and 25 village farmers. The control group comprised of 27 Syphilis controls and 40 healthy controls. Of the total study entrants, 186 were tested for Leptospira antibodies by IgM ELISA and 41 by microscopic agglutination test (MAT). ELISA results of 45 patients were further tested by MAT for comparative evaluation. Out of 160 patients of the test group 56(35.0%) were positive for Leptospira antibodies. The positivity was 18(32.73%) amongst PUO patients, 15(35.71%) of the farm workers, 15(39.47%) of hepatitis patients and 8(32.0%) farmers. Leptospira antibodies were not detected in any of the controls. The antibody positivity was seen in 33(32.04%) of the 103 urban patients and 23(40.35%) of 57 rural patients. Out of 56 Leptospira cases, in 39(69.64%) history of animal contact was present. The common clinical features in these patients included fever in 51(91.07%), myalgia 48(85.71%), headache 42(75.0%), Anorexia 31(55.35%), Jaundice 24(42.86%) and nausea/vomiting in 21(37.5%). Of the 45 ELISA results compared with that of MAT, there was 86.67% agreement between the tests.

2,4,6-Trinitrotoluene (TNT) is an important occupational and environmental pollutant. In TNT-exposed humans, notable toxic manifestations have included aplastic anaemia, toxic hepatitis, cataracts, hepatomegaly and liver cancer. Therefore, it is important to develop protection measures and to monitor workers involved in the clean-up of ammunition sites. Haemoglobin (Hb) adducts of TNT, 4-amino-2,6-dinitrotoluene (4ADNT) and 2-amino-4,6-dinitrotoluene (2ADNT), and the urine metabolites of TNT, 4ADNT and 2ADNT were found in 22-50% of the exposed workers, but not in the control group. The exposed workers were wearing protective equipment. The levels of erythrocytes, haemoglobin, creatinine, serum glutamic pyruvic transaminase and lymphocyte levels were significantly lower in the exposed workers than in the non-exposed workers. The levels of blood urea and reticulocytes were significantly higher in the exposed workers than in the non-exposed workers. Headache (26%), mucous membrane irritation (16%), sick leave (18%), lassitude (8%), anxiety (6%), shortness of breath (3%), nausea (5%) and allergic reactions (8%) were reported by the exposed workers. In a further analysis the U-4ADNT levels and the Hb-adduct levels were compared to the blood parameter and the health effects. The blood parameters were not significantly different between the U-4ADNT positive and U-4ADNT-negative group. Headache, mucous membrane irritation, sick leave, lassitude, anxiety, shortness of breath and allergic reactions were statistically not different between the two groups. Also in the workers with Hb-4ADNT adducts no significant negative changes were seen in regards to the changes of the blood parameters or the health effects. According to the results of the present study, it appears that the blood parameter changes and the health effects are more influenced by other factors than by the internal exposure to TNT.

Acute Q fever is a worldwide zoonosis caused by Coxiella burnetii infection. In Taiwan, cases of acute Q fever increased during 3 y of observation, especially at Kaohsiung County and City in southern Taiwan. From 15 April 2004 to 15 April 2007, a total of 67 cases of acute Q fever were identified at E-Da hospital located at Kaohsiung County. 19 (28.4%) patients had a history of travel in rural areas and only 1 had been outside southern Taiwan. 21 (31.3%) patients had a history of animal contact. 20 (30.8%) of the 65 examined patients had underlying chronic hepatitis B or hepatitis C virus infection. Fever (98.5%), chills (79.1%), headache (79.1%), relative bradycardia (44.8%), elevated aminotransferases (100%), and thrombocytopenia (74.6%) were common manifestations. 12 (19.0%) cases had abnormal findings on chest X-ray. Fatty liver (50.0%) and hepatomegaly and/or splenomegaly (41.9%) were found by abdominal image examinations. 42 (76.4%) of 55 cases had defervescence within 3 d after treatment, whereas 4 (7.3%) had spontaneous remission. Acute Q fever is an endemic infectious disease with hepatitis rather than pneumonia as the major presentation in southern Taiwan and the emergence of Q fever is due to increased alertness for the disease by physicians.
