RESUMO
Rickettsiae are in many places of the world emerging or reemerging pathogens. The spotted fevers group (SFG) composes a large group of tick- and mite-borne zoonotic infections that are caused by closely related rickettsiae. The SFG rickettsiae of Southeast Asia are yet to be identified. Earlier reports have documented the endemicity of rickettsioses among adults in the Himalayan belt but no confirmed case of spotted fever have been reported from this region of India. We present two cases of SFG rickettsioses; from the northern hilly region of India that were confirmed using specific microimmunofluorescence assay.

OBJECTIVE: To study the relationship of Weil-Felix test and microimmunofluorescence test. METHODS: Sera of 21 patients with clinical diagnosis of scrub typhus were subjected to Weil-Felix and Microimmunofluorescence tests. RESULTS: On Weil-Felix test, 13 (62%) sera showed titers 1: > or = 40-320. 7 patients showed titers 1: > or = 320, 3 showed titers 1 : 160, 2 showed titers 1 : 80 and 1 patients showed titers 1 : 40, to Proteus OXK antigen. All 21 sera showed significant titers to O. tsutsugamushi on microimmunofluorescence. CONCLUSION: Weil-Felix test is not a very sensitive test in diagnosis of scrub typhus but due to of lack of availability of definitive tests in India it canbe a useful tool when used and interpreted in the correct clinical context.

Poncet's disease is a rare polyarthritis occurring in patients with tuberculous infection. We describe two cases of polyarthritis, one secondary to pulmonary tuberculosis, the other secondary to tuberculous infection of lymph nodes. In both cases the arthritis rapidly subsided with chemotherapy.

A case of congenital dyserythropoietic anaemia presented with recurrent jaundice and painful splenomegaly. There was binuclearity, internuclear chromatin bridges, megaloblastic changes in erythrocyte precursors and positive acidified serum test with normal serum.
