This paper investigates the distribution of the disease in regions of north, north-east, central and south Thailand. Between the earliest recorded of outbreak of trichinosis in Mae Hong Son Province in 1962 and 2006, there have been 135 outbreaks involving 7340 patients and 97 deaths in Thailand. The highest number of cases, 557, was recorded in 1983. Most infected patients were in the 35-44 year age group, and the disease occurred more frequently in men than women during 1962-2003, with no significant sex difference during 2004-2006. Outbreaks were most common in the northern areas, especially in rural areas where raw and under-cooked pork and/or wild animals are eaten. Human infections occur annually in northern Thailand during communal feasts celebrating the Thai New Year. Trichinosis causes have been reported every year, supporting the need for planning education programs.展开更多

Methods： The clinical characteristics of 2 patients diagnosed and treated in our hospital were reported, and 42 cases that had been reported from years 1993 to 2007 are analyzed. Results： In our report, the first patient attacked serious asthma time after time, the second patient suffered from bronchiectasis with a protracted infection course. Forty-four cases all have pathogen examination and parasitic expertise. The most common symptoms are fever, cough and expectoration. 1/3 of the patients have increased acidophilic granulocyte in peripheral blood. Chest X film and CT scanning suggest changes were similar to pneumonia. Chronic cases are manifested with bronchial asthma, bronchiectasis and pulmonary abscess. L. blattarum found in phlegm or specimen collected by bronchoscopy provides the most reliable evidence for the diagnosis of this disease. Conclusion： Bronchopulmonary L. blattarum infection is a new kind of diseases. The clinical manifestations are similar to pneumonia, asthma, bronchiectasis infection or pulmonary abscess. L. blattarum found in sputum smear, bronchoscopic brush smear, bronchoscopic biopsy smear, or hronchoalceolar lavage under microscope is the foundation of the diagnosis. The pathogen species has not been finally confirmed. It is still unclear how the pathogen exists in the natural environment, how to transmit to persons and what kind of people would suffer from the disease more easily. Treatment only with antibiotics is not effective to this disease. Metronidazole with dosage of 0.5 g per time and twice per day was effective to most patients, the period of treatment need to last 14-38 d, but multidrug resistance case had been reoorted.展开更多
