The follow-up study of the health of teachers (n = 56) of three mould damage schools were done with self-administered symptom questionnaire before and 1 year after the remediation of school buildings. Technical and microbiological investigations were done parallel at the same time. In the beginning of the study symptoms of allergic rhinitis, sinusitis, conjunctivitis and fatigue were high compared to normal population and 1 year after the intervention a decrease in fatigue (OR = 0.4) and headache (OR = 0.2) was observed. An association between female gender and sinusitis was found before the remediation (OR = 8.1). Age over 40 years was a risk factor for voice problems and more than 10 working years at the same school were associated with increased risk for conjunctivitis (OR = 8.5) and headache (OR = 5.4). Other exposure situations such as mould problems at home and mould exposure during leisure time also have an effect on teachers' health. Significant reduction was found in symptoms of fatigue and headache after the cessation of exposure, while respiratory symptoms need much longer time to relieve after the remediation. Age, female gender, atopy, long-term exposure time and other exposure situations might be the risk factors for prolonged symptoms among mould exposed teachers.

This study was designated to describe clinical and biological features of patients with a suspected diagnosis of dengue fever/dengue hemorrhagic fever during an outbreak in Central Vietnam. One hundred and twenty-five consecutive patients hospitalized at Khanh Hoa and Binh Thuan Provincial hospitals between November 2001 and January 2002 with a diagnosis of suspected dengue infection were included in the present study. Viruses were isolated in C6/36 and VERO E6 cell cultures or detected by RT-PCR. A hemagglutination-inhibition test (HI) was done on each paired sera using dengue antigens type 1-4, Japanese encephalitis (JE) virus antigen, Chickungunya virus antigen and Sindbis virus antigen. Anti-dengue and anti-JE virus IgM were measured by a capture enzyme-linked immunosorbent assay (MAC-ELISA). Anti-dengue and anti-JE virus IgG were measured by an ELISA test. Dengue viruses were isolated in cell culture and/or detected by RT-PCR in 20.8% of blood samples. DEN-4 and DEN-2 serotypes were found in 18.4% and 2.4% of the patients, respectively. A total of 86.4% of individuals had a diagnosis of acute dengue fever by using the HI test and/or dengue virus-specific IgM capture-ELISA and/or virus isolation and/or RT-PCR. The prevalence of primary and secondary acute dengue infection was 4% and 78.4%, respectively. Anti-dengue IgG ELISA test was positive in 88.8% of the patients. In 5 cases (4%), Japanese encephalitis virus infection was positive by serology but the cell culture was negative. No Chickungunya virus or Sindbis virus infection was detected by the HI test. In patients with acute dengue virus infection, the most common presenting symptom was headache, followed by conjunctivitis, petechial rash, muscle and joint pain, nausea and abdominal pain. Four percent of hospitalized patients were classified as dengue hemorrhagic fever. The clinical presentation and blood cell counts were similar between patients hospitalized with acute dengue fever and patients with other febrile illnesses.

West Nile virus (WNV) is a member of the Flaviviridae family, genus Flavivirus. Its reservoir hosts are wild birds. Infection is transmitted to humans by infected mosquitoes of the genus Culex. In most cases, it is either asymptomatic or manifests itself as mild fever. Typically, WNV illnesshas a sudden onset with fever above 39 degrees C and accompanying symptoms such as chills, headache, arthralgia, myalgia, back ache, cough and sore throat. Gastrointestinal symptoms are frequently reported. Generalized lymphadenopathy and conjunctivitis may develop. In some patients the infection can progress to meningoencephalitis. Diagnosis is currently based on detection of IgM antibodies in blood and cerebrospinal fluid or direct detection of WNV RNA.

Patients exposed to the toxic dinoflagellate Pfiesteria develop an illness characterized by secretory diarrhea, conjunctival irritation, skin lesions, and varying degrees of neurologic manifestations. The anion-exchange resin, cholestyramine has been reported in one small case series to be an effective treatment of severe diarrhea associated with Pfiesteria intoxication. A 54-year-old man traveled to the Dominican Republic where he went swimming in what he describes as "dirty ocean water". Within an hour, he noted a generalized burning and itching of his skin. Later on, he noted pruritic vesicular skin lesions, intense frontal headache, and conjunctivitis. A few days later, he complained of abdominal cramping, nausea, and hourly episodes of watery, non-bloody diarrhea. Due to the constellation of symptoms, Pfiesteria intoxication was suspected. On arrival in the United States, he sought medical care for continued symptoms. Physical examination was remarkable for conjunctival injection, linear vesicular lesions (5 cm in length) over his right ankle and left orbit as well as erythema over foreskin of his penis. Mental status and memory were normal. Laboratory studies revealed an elevated serum creatinine, which eventually normalized, and stool studies were negative for leukocytes, blood, and enteric pathogens. Intense diarrhea persisted until he was started on cholestyramine (4 g PO tid). The diarrhea resolved within 2 hours of starting treatment. The headache was initially treated with narcotic agents but only resolved with IV diphenhydramine (25 mg q 4 h). Cholestyramine and diphenhydramine appear to be effective therapeutic agents for tropical-related diarrhea and headache, respectively.

Trichinellosis is a worldwide zoonotic disease caused by a nematode Trichinella sp. Cases of Trichinella spiralis infection in Slavonski Brod were investigated. A total of 64 trichinellosis cases were notified to the Institute of Public Health, Brod-Posavska County between October and November 2004. There were 64 patients, 32 of them female, age range 3-67, mean 35 years. The mean incubation period was 3 (range 1-5) weeks. The epidemic started in October and terminated 39 days later. The patients ate smoked sausages. Trichinella spiralis was identified in sausages by artificial digestion. Among 64 people infected, 65% had facial and/or periorbital edema, 56% diarrhea, 53% myalgia, 48% fever, 26% headache, 23% weakness, 6% conjunctivitis, 6% cough and 3% vomitus, 6% of patients were free from symptoms and 17% were hospitalized. Eosinophils were elevated in 92%, creatinine kinase in 60%, and lactate dehydrogenase in 59% of patients; 97% of patients were positive for Trichinella spiralis on indirect immunofluorescence.

A 63-year-old man presented with chronic headache and bilateral hearing loss. A physical examination showed bilateral conjunctivitis. Circulating anti-Cogan peptide antibodies were detected by dot blot analysis. He was diagnosed as having Cogan's syndrome (CS). Steroid therapy led to dramatic improvement of his symptoms and abnormal laboratory findings. During a tapering course of steroid therapy, he suffered from headache. An ophthalmoscopic examination revealed papillary edema. Magnetic resonance imaging of the brain showed hypertrophic cranial pachymeningitis (HCP). After steroid pulse therapy, HCP was improved. To our knowledge, this is the first case of CS complicated with HCP.

Mycoplasma pneumoniae-associated mucositis is a rarely described complication of M. pneumoniae infection presenting with ocular, oral, and genital involvement but without the typical skin lesions seen in Stevens-Johnson syndrome. A 27-year-old man with a past history of asthma presented at the emergency room with a 1-week history of cough (initially non-productive but subsequently associated with non-bloody mucopurulent sputum), fever, myalgias, headache, and progressive dyspnea. Two days before admission he had commenced amoxicillin/clavulanic acid with no improvement. The patient reported bilateral conjunctival injection and hemorrhagic ulcers on the lips commencing the day prior to admission. Physical examination revealed fever (39 degrees C), bilateral exudative conjunctivitis, painful hemorrhagic ulcers on the lips, tongue, and oral mucosa, small scrotal erosions, erythema of the penile meatus, and small erythematous bullae on the dorsum of each hand; subsequently, the patient developed bullae at the venipuncture site on his right arm. Laboratory tests revealed positive IgM serology for M. pneumoniae, with titer elevation. The patient was successfully treated with levofloxacin and prednisolone. Our case appears to be the first adult patient described with M. pneumoniae-associated mucositis, which has previously been reported only in pediatric patients. This is also the first reported instance of a case of M. pneumoniae-associated mucositis treated with levofloxacin and prednisolone. M. pneumoniae infection should be considered in all cases of mucositis, and treatment of this condition with levofloxacin and prednisolone seems to be effective.

Short-term effects of air pollution on common morbidity are largely unknown. The authors explored links between daily levels of air pollution (nitrogen dioxide, ozone, and particulate matter less than 10 microm in diameter (PM(10))) and medical home visits made for diverse reasons in Bordeaux, France, during 2000-2006. Daily numbers of visits were obtained from a network of general practitioners. The excess relative risk (ERR) of a visit for each indicator associated with increased pollutant levels was estimated by fitting a Poisson regression model, controlling for well-known confounding factors and temporal trends. Positive and significant associations were found between air pollution and most health indicators. A 10-microg/m(3) increase in PM(10) levels was associated with increases in visits for upper and lower respiratory diseases (ERRs were 1.5% (95% confidence interval (CI): 0.3, 2.7) and 2.5% (95% CI: 0.5, 4.4), respectively), headache and asthenia (ERR = 3.5%, 95% CI: 1.3, 5.9), and skin rash and conjunctivitis (ERR = 3.2%, 95% CI: -0.2, 6.8). Significant associations were also found between nitrogen dioxide and ozone and several health indicators. Distributed-lag models showed no harvesting effect, and some effects persisted up to 15 days after exposure increased. These results suggest that considering only the most severe effects of air pollution leads to underestimation of its impact on public health.

Despite advances in therapy, chronic lymphocytic leukemia remains an incurable disease and novel, effective therapies are needed. In this open-label, dose-escalation, phase I study, dacetuzumab (IgG1 humanized monoclonal antibody) was administered to 12 adults, all of whom had received several prior systemic therapies (median, 4; range, 2-11). Intrapatient dose escalation (maximum weekly doses of 3-8 mg/kg) was used to diminish first-dose-related inflammatory symptoms. No dose-limiting toxicities or dose-dependent trends in adverse events (AEs) were observed. The most common AEs (in >/=2 patients) were fatigue, headache, anorexia, conjunctivitis, hyperhidrosis, and night sweats, all of which were mild or moderate. No deaths, serious AEs, or discontinuations due to AEs occurred. Although no patient achieved an objective response, five patients demonstrated stable disease after 1 cycle of therapy, with no discernable correlation between dacetuzumab dose and outcome. This modest single-agent activity may warrant further testing of dacetuzumab in combination with other chronic lymphocytic leukemia therapies.

Kawasaki's disease is a disease of unknown cause. The characteristic clinical features of Kawasaki's disease are fever> or =102 degrees F for> or =5 days accompanied by a bilateral bulbar conjunctivitis/conjunctival suffusion, erythematous rash, cervical adenopathy, pharyngeal erythema, and swelling of the dorsum of the hands/feet. Kawasaki's disease primarily affects children and is rare in adults. In children, Kawasaki's disease is more likely to be associated with aseptic meningitis, coronary artery aneurysms, and thrombocytosis. In adult Kawasaki's disease, unilateral cervical adenopathy, arthritis, conjunctival suffusion/conjunctivitis, and elevated serum transaminases (serum glutamic oxaloacetic transaminase [SGOT]/serum glutamate pyruvate transaminase [SGPT]) are more likely. Kawasaki's disease in adults may be mimicked by other acute infections with fever and rash, that is, group A streptococcal scarlet fever, toxic shock syndrome (TSS), and Rocky Mountain Spotted Fever (RMSF). Because there are no specific tests for Kawasaki's disease, diagnosis is based on clinical criteria and the syndromic approach. In addition to rash and fever, scarlet fever is characterized by circumoral pallor, oropharyngeal edema, Pastia's lines, and peripheral eosinophilia, but not conjunctival suffusion, splenomegaly, swelling of the dorsum of the hands/feet, thrombocytosis, or an elevated SGOT/SGPT. In TSS, in addition to rash and fever, there is conjunctival suffusion, oropharyngeal erythema, and edema of the dorsum of the hands/feet, an elevated SGOT/SGPT, and thrombocytopenia. Patients with TSS do not have cervical adenopathy or splenomegaly. RMSF presents with fever and a maculopapular rash that becomes petechial, first appearing on the wrists/ankles after 3 to 5 days. RMSF is accompanied by a prominent headache, periorbital edema, conjunctival suffusion, splenomegaly, thrombocytopenia, an elevated SGOT/SGPT, swelling of the dorsum of the hands/feet, but not oropharyngeal erythema. We present a case of adult Kawasaki's disease with myocarditis and splenomegaly. The patient's myocarditis rapidly resolved, and he did not develop coronary artery aneurysms. In addition to splenomegaly, this case of adult Kawasaki's disease is remarkable because the patient had highly elevated serum ferritin levels of 944-1303 ng/mL; (normal<189 ng/mL). To the best of our knowledge, this is the first report of adult Kawasaki's disease with highly elevated serum ferritin levels. This is also the first report of splenomegaly in adult Kawasaki's disease. We conclude that Kawasaki's disease should be considered in the differential diagnosis in adult patients with rash/fever for> or =5 days with conjunctival suffusion, cervical adenopathy, swelling of the dorsum of the hands/feet, thrombocytosis and otherwise unexplained highly elevated ferritin levels.
