Repeated blood cultures were negative in a six-year-old boy with high septic temperature. Rheumatoid arthritis, typhoid and brucellosis were excluded. There was no evidence of leukaemia (bone-marrow tests). There was hepatomegaly with increased transaminase activity. Cortisone treatment was begun for suspected collagen disease. Several liver needle biopsies at first revelaed increasingly severe necrotising changes, predominantly in the centres of the acini. There were no parasites demonstrable histologically. The spleen was increased in the isotope scan but, covered by the liver, not definitely palpable. Diagnosis of mediterranean Kala-Azar disease was then suspected (the parents reporting a camping holiday in Yugoslavia) and finally proven serologically. The previously treatment-resistant disease improved dramatically after administration of trivalent antimony (Fuadin).

Visceral leishmaniasis was detected incidentally in a patient with acute lymphoblastic leukaemia in remission, during maintenance therapy. Absence of fever, a normal haemogram, normal serum globulins, a negative serology and testicular involvement were the hallmarks of the case. Treatment with sodium stibogluconate (20 mg/kg for 55 days) failed. Subsequent therapy with pentamidine resulted in complete parasite clearance. Prolonged therapy with pentavalent antimony compounds or a higher dose of second line drugs such as pentamidine are recommended for complete clearance.

Visceral leishmaniasis is a rare but potentially life threatening opportunistic protozoan infection in immunocompromised patients. The clinical manifestations in these patients are unusual and the diagnosis is difficult. They need prolonged treatment and are liable to have relapses. Here we report three patients with haematological malignancy (one with acute lymphoblastic leukaemia, one with chronic myeloid leukaemia, and one with myelodysplastic syndrome) complicated with visceral leishmaniasis. The clinical presentation, diagnosis, and outcome are discussed.

Visceral leishmaniasis is suspected on the basis of clinical findings and a pancytopenic blood picture and is usually confirmed by the detection of amastigotes (Leishman-Donovan bodies) in a bone marrow aspirate. We describe a child on maintenance treatment for acute lymphoblastic leukaemia who developed visceral leishmaniasis and in whom amastigotes could not be detected in repeated bone marrow aspirates. Immunofluorescence antibody testing was positive. Immunocompromised patients in endemic areas who develop features of visceral leishmaniasis should have serological tests performed in addition to bone marrow aspiration in order to maximize the chances of making a diagnosis.

Human brucellosis is an important animal transmitted disease of man. Although, the cases have been recorded all over the world, the prevalence is higher in developing countries. Lack of sufficient knowledge about the disease among the physicians, its under-diagnosis or misdiagnosis and absence of effective prevention and management strategies are attributed to the widespread of the disease. Increase in the occurrence of animal brucellosis has also resulted indirectly in an increase in the prevalence of human infection. Absence of characteristic clinical symptoms, chronic nature of the infection and difficulty in isolation of the causal agent from the patients make the diagnosis of the disease more difficult. The serological tests employed for diagnosing human brucellosis vary in terms of their sensitivity and specificity. Therefore, a combination of serological tests is desirable. Currently no vaccine is available against human brucellosis, which could check the spread of the disease effectively. It is suggested that clinicians investigate the cases of pyrexia of unknown origin (PUO) for brucellosis. It is desirable that specimens from cases of tuberculosis, typhoid, rheumatoid arthritis, urogenital infections, kala-azar, cirrhosis, bacterial endocarditis, leukemia and filariasis should also be screened for brucellosis in man. The cases of meningitis of unestablished etiology as the cases of human brucellosis are often misdiagnosed as cases of typhoid or tuberculosis.

The authors describe an unusual case of a disseminated bacille Calmette-Guerin (BCG) infection in a 3-month-old girl who presented with a huge hepatosplenomegaly, fever, and pancytopenia. Clinically, an infantile kala-azar or lymphoma/leukemia was suspected. However, after thorough clinical and paraclinical investigations, the case was diagnosed as a disseminated BCG infection. The child died 2 weeks after starting antituberculosis treatment. Autopsy revealed diffuse histiocytic infiltration in the liver, spleen, and mesenteric lymph nodes, which were loaded with acid-fast bacilli. Three interesting findings were noticed in this case: circulating monocytes in the peripheral blood were loaded with ghost acid-fast bacilli; bone marrow smears revealed numerous Gaucher cell-like macrophages loaded with negative images of Mycobacterium tuberculi; and there was extensive marrow necrosis. These findings have not been previously reported in the literature.

Tuberculosis is one the commonest disease affecting peripheral lymph node and cervical tubercular lymphadenitis are frequently encountered in Otolaryngological practice. Three hundred fifty six (356) cases of Fine Needle Aspiration for Cytology (FNAC) positive tubercular lymphadenitis were studied from January 2006 to December 2008. FNAC positive but histopathologically negative cases were excluded from the study. Among 356 cases of FNAC positive cervical lymphadenopathy 300 cases (84.27%) were confirmed tuberculosis on histopathological examination. Remaining 50 cases (15.73%) were diagnosed as nontubercular lymphadenitis where nonspecific lymphadenitis was the commonest finding 34(9.55%) followed by metastatic carcinoma 7(1.97%), lymphoma 6(1.08%), Kikuchiz's disease 6(1.08%), Kala-Azar 2(0.56%) & Leukemia 1(0.28%). Most of the patients presented with only multiple lymph node swelling with other symptoms, such as fever 18(5.06%), pain (15.7%), tenderness 53(14.88%), weight loss 29(8.14%), anorexia 33(9.26%). Following observations are evident from this study: i) Disease is comparatively common between 12-35 years ii) Multiple matted/discrete lymph nodes are the earliest presentation iii) Multiple lymph node is the most consistent finding for clinical diagnosis. iv) Very few patients have constitutional symptoms v) Suppuration with or without abscess formation although confirms the diagnosis even then certainty is very essential. Though the evidence of cervical tuberculosis was thought to be decreasing in developing countries the real picture seems to be different. Random survey among the whole population was not done in any country rather hospital based laboratory research was made.

Here we describe a case of paediatric visceral leishmaniasis recorded in an infant initially suspected for acute lymphoblastic leukaemia due to the clinical and haematological presentation. Eventually the patient was found positive for Leishmania infantum infection and successfully treated. This case emphasises how pivotal a 'One Health' approach is for diagnosing this zoonotic disease; highlighting the importance of including Visceral Leishmaniasis in the differential diagnosis of leukaemia-like syndromes in infants travelling to, and living in, the Mediterranean region.
