Item Acute hearing loss in febrile patients: a predictor of scrub typhus(Sri Lanka Medical Association, 2005) Premaratna, R.; Chandrasena, T.G.A.N.; Dassanayake, A.S.; Loftis, A.; Dasch, G.A.; de Silva, H.J.INTRODUCTION: Rickettsial infections are re-emerging in Sri Lanka. Complications such as pneumonitis, myocarditis and encephalitis can occur late in the disease, and result in a high mortality. Early diagnosis reduces morbidity and mortality, but as laboratory facilities for definitive diagnosis are lacking, early diagnosis depends on clinical suspicion. Acute hearing loss which occurs in about 30% of patients has been recognised as a predictor of scrub typhus. METHODS: Six patients admitted to hospital with high fever and hearing impairment were further investigated. RESULTS: All were females with a mean age of 65 years (SD 2). The mean duration of fever at presentation was 12 days (SD 1), Hearing impairment was observeItem Contribution of rickettsioses in Sri Lankan patients with fever who responded to empirical doxycycline treatment(Oxford University Press, 2010) Premaratna, R.; Rajapakse, R.P.V.J.; Chandrasena, T.G.A.N.; Nanayakkara, D.M.; Bandara, N.K.B.K.R.G.W.; Kularatne, S.A.M.; Eremeeva, M.E.; Dasch, G.A.; de Silva, H.J.Twenty-eight febrile Sri Lankan patients with undiagnosed fever for 7 days after hospital admission, who responded to empirical treatment with doxycycline, were retrospectively investigated using microimmunofluorescence assay to verify whether they had rickettsial infection. Eleven (39%) patients were confirmed as having spotted fever group rickettsioses and 10 (36%) as having Orientia tsutsugamushi. Seven were negative for all tests. This suggests that greater use of doxycycline appears justified for patients with undiagnosed fever in settings where rickettsial diseases are endemic or re-emerging with inadequate diagnostic facilities.Item Rickettsioses presenting as major joint arthritis and erythema nodosum: description of four patients(Springer International, 2009) Premaratna, R.; Chandrasena, T.G.A.N.; Rajapakse, R.P.V.J.; Eremeeva, M.E.; Dasch, G.A.; Bandara, N.K.B.K.R.G.W.; de Silva, H.J.Erythema nodosum and aseptic arthritis are recognized associations of rickettsial infections. However, they usually present with a febrile illness rather than with severe arthritis. We report three patients who presented with incapacitating major joint arthritis and one who presented with severe spondyloarthropathy in addition to major joint arthritis due to serologically confirmed Orientia tsutsugamushi and Rickettsia conorii infections. All of them had erythema nodosum and low-grade fever. They had rapid clinical response to doxycycline.Item Acute hearing loss due to scrub typhus: a forgotten complication of a reemerging disease(Oxford University Press, 2006) Premaratna, R.; Chandrasena, T.G.A.N.; Dassanayake, A.S.; Loftis, A.D.; Dasch, G.A.; de Silva, H.J.We describe 6 patients with scrub typhus who presented with acute hearing loss, a forgotten complication of this reemerging disease. They were admitted with fever of 10-14 days' duration and had clinical evidence of deafness and pneumonitis. Five patients had eschars, which prompted the diagnosis of typhus fever and led to early institution of treatment. Deafness has been described as a clue to the diagnosis of scrub typhus; awareness of this symptom facilitated early diagnosis in 4 of 5 patients who recovered. Acute hearing loss or hearing impairment in a febrile patient should arouse strong suspicion of scrub typhus.
