Dengue Viral Myositis Complicated with Rhabdomyolysis and Superinfection of Methicillin-Resistant Staphylococcus aureus

Dengue is endemic in Sri Lanka and the physician should be aware of different and unusual presentation of the illness. Rhabdomyolysis is a well-known complication following many viral and bacterial infections; however, only a few cases have been reported with dengue viral infections. Further occurrence of coinfection by dengue and bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) has been underestimated, and few reports have been published so far. This case describes a 17-year-old boy who presented with prolonged severe myalgia, dark red urine, and a febrile illness that was diagnosed as having dengue viral myositis, dark red urine, and a febrile illness that was diagnosed as having dengue viral myositis complicated with rhabdomyolysis and superinfection of MRSA. Despite intensive care management, he died due to multiorgan failure. Autopsy and serological studies confirmed the diagnosis. This case stresses that red-coloured urine in dengue patients is not always due to haematuria, and if a patient's vital signs do not respond to appropriate fluid management in DHF, sepsis from a secondary pathogen including MRSA should be suspected

Dengue fever manifesting with tetany as the first presentation of primary hypoparathyroidism: a case report

Abstract Background Primary hypoparathyroidism is associated with diverse variety of symptomatology of hypocalcemia including seizures and tetany. We report a case of previously undiagnosed asymptomatic primary hypoparathyroidism with extensive basal ganglia calcifications presenting for the first time with hypocalcemic tetany during acute dengue infection. Although hypocalcemia is known to occur in dengue infection symptomatic hypocalcemia is very infrequent. Case presentation A 32 year old male with short stature who has undergone bilateral cataract surgery 2 years ago but who was otherwise healthy, presented with fever and generalized body aches of 3 days duration and carpal spasms/tetany occurring on the third day of the illness. He was diagnosed to have acute dengue fever along with severe hypocalcemia. Subsequent workup confirmed that the patient had primary hypoparathyroidism with extensive basal ganglia and cerebellar calcifications which was previously undiagnosed. His acute illness and hypocalcemia was managed successfully and was commenced on regular calcium supplementations to alleviate the hypocalcemic effects of his chronic illness. Conclusion Clinical features of hypocalcemia may not commonly manifest up to the same degree of severity of hypocalcemia in primary hypoparathyroidism even till late adulthood but potential early clues such as short stature and premature cataract should be actively investigated. Worsening of already existing hypocalcemia during acute dengue fever led to the ultimate diagnosis of primary hypoparathyroidism in this patient which was lifesaving
