We report on a 20-year-old man who had scrub typhus with the unusual neurologic complication of brachial plexus neuropathy. The clinical features of fever, headache, pneumonitis, eschar, high Weil-Felix OX-K agglutination and Rickettsia tsutsugamushi immunofluorescence titers confirmed the diagnosis of scrub typhus. Brachial plexus neuropathy was proven by an electrophysiologic examination. He had a nearly complete recovery after adequate medical treatment.

Between October, 1985, and February, 1987, 28 (8.7%) cases of scrub and murine typhus were diagnosed among 320 children with greater than or equal to 1 week history of obscure fever. Scrub typhus is a rural disease and characterized by fever, tachypnea and hepatosplenomegaly. Skin rash was rare and eschar was absent. Four patients had pneumonia and two had meningitis. Murine typhus, more an urban disease, was milder and half the patients presented exclusively because of night fever. Slightly enlarged liver and skin rash were the only significant physical signs. Lacking the classical textbook presentations, both rickettsioses often were missed or diagnosed as enteric fever. Recognition is important because patients with either disease respond well to treatment with chloramphenicol or doxycycline.

Scrub typhus (tsutsugamushi disease) is an acute infectious disease caused by Rickettsia tsutsugamushi transmitted through the bite of larvae of certain trombiculid mites. Geographical distribution in Asian-Pacific region is much of the roughly triangular area bounded by Japan, Pakistan and Australia. It is an endemic illness in the Pescadores Islands, but has scarcely been reported in central Taiwan. An eleven-year-old boy was admitted to Changhua Christian Hospital with the chief complaints of fever, lethargy and skin rash for seven days. On physical examination, he was found to have painless eschar, conjunctivitis, meningoencephalitis, pneumonitis, ascites, jaundice, hepatomegaly, liver function impairment and thrombocytopenia. His Proteus OX-K agglutinin titer increased from 1:160 in the acute sera to 1:640 in the convalescent sera. A greater than four-fold rise (greater than 1:640) in antibody titers to Karp, Gilliam, Kato strains of R. tsutsugamushi between acute and convalescent sera were demonstrated by immunofluorescent antibody. The patient was treated with minocycline and chloramphenicol and was completely recovered.

Four cases of scrub typhus pneumonitis are reported. Diagnosis was confirmed by positive Weil-Felix OX-K reaction and immunofluorescent antibody test for Rickettsia tsutsugamushi. Two patients presented with atypical pneumonia and two had overwhelming pneumonia resembling adult respiratory distress syndrome. All patients made a full recovery after appropriate treatment.

In the unique environment of Australia's tropical north there are endemic diseases inherited from Gondwana, others introduced from the north and from Europe, and a wide range of particularly venomous animals. There is continuing disparity in morbidity and mortality between Aboriginal people and other Australians in tropical areas and elsewhere. This is being addressed by the National Aboriginal Health Strategy, which emphasises social, environmental and economic issues, as well as control and coordination of services by Aboriginal and Torres Strait Islander communities. While the re-introduction of malaria remains a potential threat, together with other infections, current diseases in tropical Australia are being better elucidated; melioidosis is now recognised as the commonest cause of fatal [corrected] community-acquired pneumonia in the Top End of the Northern Territory, and a new focus of scrub typhus has been found. Sexually transmitted diseases are an urgent issue, especially for Aboriginal communities, given the potential impact of the human immunodeficiency virus.

A 21-year-old man presented with fever, rash, seizure, stiff neck and rapidly progressive bilateral pulmonary infiltrates. Cerebrospinal fluid (CSF) study revealed pleocytosis with predominant polymorphonuclear cells, and hypo-glycorrhachia. Status epilepticus occurred, followed by acute respiratory distress syndrome with respiratory failure. Blood and CSF cultures for bacteria were negative, but an indirect immunofluorescence assay revealed a fourfold rise in antibody to Rickettsia tsutsugamushi in paired serum and a 1:2560 (+) IgM antibody titer. Severe scrub typhus with meningoencephalitis and extensive pneumonitis was diagnosed. The patient survived after intravenous minocycline therapy and intensive care, including aggressive seizure control, supportive mechanical ventilation and avoidance of fluid overloading. He had a nearly complete recovery. Practicing physicians in Taiwan should be aware of this reportable disease and its potentially serious complications if not promptly diagnosed and treated.

Scrub typhus is widely endemic in Asia. Man's behaviour and climatic changes greatly influenced the occurrence of the disease. Increasing prevalences of scrub typhus have been reported from some Asian countries and may coincide with the widespread use of beta-lactam antibiotics or to improve diagnostic facilities and/or more urbanisation into rural areas. Many cases acquired in Asia surfaced in Europe and America. The disease probably is overlooked among paediatric patients. Most patients with scrub typhus present with acute fever of unknown origin (acute FUO). Eschars are rare among Southeast Asian patients. Complications usually develop after the first week of illness. The complications include pneumonitis, meningoencephalitis, renal failure and jaundice. Improved serologic and molecular diagnostic tests are now available. Although drug-resistant strain of Orientia tsutsugamushi has been reported, the infection usually responds to simple but unpopular drugs such as doxycycline or chloramphenicol.

Scrub typhus, a mite-transmitted zoonosis caused by Orientia tsutsugamushi, is a disease endemic to Taiwan. Serious complications in scrub typhus were more common in the past 4 years than reported previously. Between August 1993 and July 1997, 33 cases of scrub typhus were admitted at Tri-Service General Hospital. Symptoms and signs were: fever (100%), chills (39%), cough (24%), headache (21%), diarrhea (18%), dyspnea (18%), eschar (60%), adenopathy (33%), and rash (21%). Nineteen percent (6/32) had obvious leukopenia (WBC < 4000/ mm3), 34% (11/32) had leukocytosis(WBC > 10,000/mm3) and 44% (14/32) had thrombocytopenia (platelet count < 100,000/mm3). Elevation of aspartate aminotransferase (AST) and elevation of alanine aminotransferase (ALT) were 81% (26/32) and 75% (24/32), respectively. Serious complications included pneumonitis 36% (12/33), acute respiratory distress syndrome (ARDS) 15% (5/33), acute renal failure 9% (3/33), myocarditis 3% (1/33) and septic shock 3% (1/33). One patient died of ARDS due to delay in diagnosis. Other patients recovered after appropriate antibiotic and intensive supportive treatments. Emerging virulent strains of O. tsutsugamushi in Taiwan might be biologically plausible. Scrub typhus should be considered in a patient with fever, varying degree of respiratory distress, particularly if there is an eschar or a history of environmental exposure in endemic areas. Prompt diagnosis, timely antimicrobial therapy and intensive supportive care are important for ARDS and other life-threatening complications.

We report a case of scrub typhus pneumonitis in a laboratory worker who apparently acquired it through the respiratory tract. The patient was suffering from fever, cough and dyspnea. He had both cervical and axillary lymphadenopathy, and hepatomegaly. A chest X-ray showed interstitial infiltrates. A diagnosis of scrub typhus was established upon isolation of Orientia tsutsugamushi. 12 days before the patient showed symptoms, he had purified O. tsutsugamushi proteins from infected cells using an ultrasonication method which could generate aerosols containing O. tsutsugamushi.

We studied 73 Thai children with scrub typhus (median age 9 years, range 3-14 years, male:female ratio 1.8:1). Most patients (86%) lived in rural areas. They presented with subacute fever (median, 9 d) with vomiting (35%), hepatomegaly (59%), splenomegaly (18%), and tachypnea (26%). Skin rash (7%), eschar (7%), and history of mite bite were rare. Blood leucocyte counts were usually normal but 19% of patients were thrombocytopenic. Twenty (22%) patients had pneumonia and six (8%) had neurological involvement. Defervescence occurred a median of 1 d and 3 d after initiation of doxycycline and chloramphenicol, respectively, and these responses were more rapid than in those who received other antibiotics or no treatment (P < 0.001). There was one death. Only 55% of the patients were initially diagnosed as having scrub typhus.
