Post-transplant lymphoproliferative disorder (PTLD) is a complication that can develop after either solid-organ or hematopoietic stem cell transplantation (HSCT). T-cell PTLD is a rare disorder, especially following autologous HSCT. Here we report a case of T-cell PTLD which occurred after autologous peripheral blood stem cell transplantation (PBSCT) for relapsed angioimmunoblastic T-cell lymphoma (AILT). Three months after the transplant, the patient developed fever with elevated plasma Epstein-Barr virus (EBV)-PCR values. The patient subsequently developed pneumonitis, hepatomegaly and marked pancytopenia due to hemophagocytosis. The patient died of multi-organ failure, despite antiviral and steroid pulse therapy. Our post-mortem study confirmed the marked proliferation of EBV-infected T-cells that differed from the original AILT clone and macrophages/histiocytes were observed in the marrow, liver, lymph nodes and lungs. Phagocytosis was most evident in the bone marrow. The patient's AILT remained in complete remission. To the best of our knowledge, this is the first case of fulminant EBV-associated T-cell lymphoproliferative disorder (LPD) following autologous HSCT.

20 children, diagnosed with scrub typhus who attended Chiang Rai Regional Hospital during a period of 6 months from June 2003 to December 2003, were studied prospectively. All cases were serologically proved to be scrub typhus by using Dipstick or indirect immunofluorescent antibody (IFA) technique. The most common clinical feature was eschar (75%). Others included hepatomegaly (65%), cough (60%), lymphadenopathy (40%), tachypnea (35%), constipation (25%), abdominal pain (20%), edema (20%), splenomegaly (15%), vomiting (15%), rash (15%) and petichia (5%) respectively. Chest radiography showed abnormalities in 85% with mostly bilateral interstitial infiltrations. Elevated of SGOT: SGPT were detected in 18 (90%) and 15 (75%) cases. Hypoalbuminemia was detected in 12 (60%) cases. Complete blood count showed PMN leukocytosis (> 60%) in 12 (60%) cases, lymphocytosis (> 40%) and atypical lymphocytosis (> 5%) in 1 (5%) case each and thrombocytopenia in 16 (80%) cases. The Weil-Felix test was positive in 1 (5%) case. Complications were pneumonia with or without pulmonary edema, meningitis and shock. Chloramphenicol and doxycycline were successfully treated and roxithromycin was not effective.

Hepatocellular carcinoma (HCC) is usually diagnosed at an advanced stage, when little remedy could be offered. There is a need for relatively affordable, available and non-invasive tests for diagnosis, staging and detection of metastasis among individuals at risk. A clinical, chest radiographic (CXR) and abdominal ultrasonographic examination was carried out to detect and evaluate the pattern of metastasis among 53 untreated patients. One patient had clinical paraparesis with no outward evidence of metastasis. CXR revealed lung metastasis in 11 (20.8%), with multifocal deposits and bilateral involvement in 10 (18.8%), and unilateral single deposit in one. Two (3.8%) patients had perihilar lymphadenopathy and consolidation, respectively, while 18 (34%) patients had elevated right hemidiaphragm and four 17.5%) had pleural effusion. One had right basal pneumonitis, multiple cavitatory lesions in the lung fields and soft-tissue wasting. No abnormality was seen in 17 (32.1%) cases. Abdominal ultrasonograph showed probe tenderness in 22 (41.5%), hepatomegaly in 49 (92.5%), with 33 (62.3%) of these having nodularities of varying sizes. The spleen was enlarged in 10 (18.9%) cases, with four (7.5%) showing irregular outline. There were eight (15.1%) cases with para-aortic lymphadenopathy. Portal hepatic lymphadenopathy was demonstrated in two (3.8%) cases, while pleural effusion was detected in seven (13.2%). Metastasis is common in HCC at presentation, the lung is the commonest site of spread. Clinically visible metastasis appears uncommon in HCC.

The aim of this study was to evaluate the clinical, epidemiological and demographical features of adult measles cases admitted to our hospital, during the measles epidemic which emerged in Europe and in our country in the year 2001. A total of 35 adult measles cases (10 male, 25 female) ages between 16-36 (mean age: 23.1 +/- 4.6) years were detected between January and June 2001. The diagnosis was based on the clinical findings, however only 11 of the cases could be serologically confirmed with the presence of measles IgM antibody positivities. Fever (91.4%), cough (94.3%) and conjunctivitis (77.1%) were the most common symptoms. All of the patients had maculopapular rash, and the presence of Koplik spots, lymphadenopathy and hepatomegaly were observed in 77.1%, 57.1%, and 5.7% of patients, respectively. Leukopenia and elevated liver enzymes were detected in 28.5% and 37.2% of the patients, respectively. Pneumonia was the most common complication which was seen in 20% of the patients. Of the cases 2.9% exhibited otitis media and 17.1% diarrhea. Spontaneous abortus occurred in one of the three pregnant women. In conclusion, measles is still an important public health problem in our country, and since it may lead to severe complications and economic and labor loss, an effective elimination programme should be obtained by the use of vaccine in two doses and effective strategies for the immunization of the target populations.

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.

An 82-year-old man was admitted with a 1-week history of chilling fever and dry cough. Laboratory tests revealed pancytopenia and elevated levels of C-reactive protein and lactic dehydrogenase (LDH). Screening for infectious diseases was negative. A bone marrow biopsy showed aspecific findings. The combination of pancytopenia, persistent fever, elevated LDH and hepatomegaly (demonstrated by ultrasound examination of the abdomen) was suggestive of the haemophagocytic syndrome. This was confirmed by very high levels of ferritin and soluble interleukin-2 receptor in the blood. In addition, re-examination of the bone marrow showed several haemophagocytic histiocytes. A polymerase chain reaction for Epstein-Barr virus (EBV) revealed a very high viral load. Since the patient had a history of an increased level of anti-EBV immunoglobulin-G, this was explained by a reactivation of the EBV infection. On the sixth day in hospital the patient developed signs of bilateral pneumonia and subsequent multiple organ failure. Despite intensive treatment the patient died. Autopsy revealed no haematological or other malignancies, but did show haemophagocytosis in many organs. It was then concluded that the patient had a virus-associated haemophagocytic syndrome, due to a reactivation of EBV, for which no underlying cause was found.

Congenital tuberculosis is a severe rapidly progressive disease which differs from neonatal tuberculosis because patients present tuberculous lesions during their first weeks of life, primary hepatic complex or hepatic caseous granulomas, confirmation of tuberculosis in placenta or in maternal genital tract (uterus or adnexa), and exclusion of birth channel or postnatal exposure. We report a case of a 20 days newborn baby admitted to the neonatal unit with fever, hepatoesplenomegaly, abdominal distension and respiratory symptoms. Abdominal echography showed ascitis, diffuse hepatomegaly and splenomegaly, focal hipoecoical spleen images and portal lymphadenopathy. Thorax X-ray with micronodular infiltrates. Maternal pneumonia with pleural effusion was reported during pregnancy. Empirical treatment was initiated with 4 antituberculous drugs: isoniazid, rifampicin, pyrazinamide and ethambutol suspecting tuberculosis. She died the next day. M. tuberculosis was obtained in a gastric lavage culture, blood cultures and post mortem spleen puncture.

Atypical community-acquired pneumonia (CAP) may be caused by zoonotic or nonpulmonary pathogens. However, atypical pathogens are systemic infectious disease accompanied by pneumonia in contrast with typical bacterial pathogens with infection limited to the lungs and absent extrapulmonary findings. Clinically and radiologically, the atypical CAP pathogens that most closely resemble each other are psittacosis, Q fever, and Legionnaires' disease. Psittacosis can usually be readily suspected or eliminated on the basis of a recent psittacine bird contact history. The 2 atypical pneumonias that most closely resemble each other clinically are Q fever and Legionnaires' disease. The epidemiology of Q fever is related to livestock, and sporadic cases are related to contact to parturient cats. In nonendemic areas, Q fever CAP mimics Legionnaires' disease most closely. Both Q fever and Legionella CAP have several clinical and laboratory features in common. However, there are subtle but important differences that allow the astute clinician to differentiate between these 2 disorders on the basis of clinical and nonspecific laboratory findings before definitive diagnostic tests results are reported. We report a case of severe Q fever CAP mimicking Legionnaires' disease in a young adult normal host. Her initial zoonotic contact history was negative, and her clinical presentation suggested Legionnaires' disease as the most likely diagnosis. Against the diagnosis of Legionnaires' disease was the patient's age and occurrence of the disease in spring time. In contrast, Legionnaires' disease is usually an infection of older individuals and occurs in late summer/fall. Although the patient did not have splenomegaly, a common finding in Q fever CAP, she did have mild hepatomegaly. Hepatomegaly is a uncommon in Q fever CAP but is not a feature of Legionnaires' disease. In the absence of a positive zoonotic contact history, the cardinal findings pointing to the diagnosis of Q fever in this case were "multiple round opacities" on chest computed tomography scan and thrombocytosis during her hospitalization. Against the diagnosis of Legionnaires' disease was the absence of hypophosphatemia and highly elevated ferritin levels. In patients with atypical pneumonias in whom the clinical presentation and nonspecific laboratory findings suggest Legionnaires' disease, but in addition have findings not associated with Legionnaires' (eg, hepatomegaly, thrombocytosis), Q fever serology should be ordered. We conclude that Q fever may closely mimic Legionnaires' disease. Severe atypical CAP with "multiple round opacities" on chest x-ray/computed tomography chest scan with elevated anti-smooth muscle antibodies or thrombocytosis should suggest the diagnosis of Q fever and prompt specific testing for Q fever. Rarely, Q fever CAP may be associated with elevated cold agglutinin titers.

Melioidosis, which is mainly prevalent in Thailand and Australia, has shown an increasing trend in India in the last few years. We carried out a retrospective study of 25 culture-proven adult cases of melioidosis who were admitted to a tertiary care hospital in southern India during June 2001 to September 2007. There was a six-fold increase in the number of cases in 2006 and 2007 as compared to 2001. Diabetes mellitus was the predisposing factor in 68% of cases, followed by alcoholism (28%). The clinical presentations were fever (80%), pneumonia and/or pleural effusion (48%), hepatomegaly (56%), joint involvement, and/or osteomyelitis (48%), splenomegaly (40%), splenic abscess (24%) and septicemia (28%). The organism, Burkholderia pseudomallei, was sensitive to co-amoxiclav, cotrimoxazole, ceftazidime, and carbapenem. The study suggests that melioidosis is an emerging infectious disease in the southwestern coastal belt of India, and it is likely to happen at much higher incidence.

Acute schistosomiasis is a systemic hypersensitivity reaction against the migrating schistosomula and eggs. A variety of clinical manifestations appear during the migration of schistosomes in humans: cercarial dermatitis, fever, pneumonia, diarrhoea, hepatomegaly, splenomegaly, skin lesions, liver abscesses, brain tumours and myeloradiculopathy. Hypereosinophilia is common and aids diagnosis. The disease has been overlooked, misdiagnosed, underestimated and underreported in endemic areas, but risk groups are well known, including military recruits, some religious congregations, rural tourists and people practicing recreational water sports. Serology may help in diagnosis, but the finding of necrotic-exudative granulomata in a liver biopsy specimen is pathognomonic. Differentials include malaria, tuberculosis, typhoid fever, kala-azar, prolonged Salmonella bacteraemia, lymphoma, toxocariasis, liver abscesses and fever of undetermined origin. For symptomatic hospitalised patients, treatment with steroids and schistosomicides is recommended. Treatment is curative in those timely diagnosed.
