Rationale: Dengue fever is a viral infection that is spread through the bites of infected female Aedes mosquitos. It can cause life threatening complications, including dengue haemorrhagic fever (DHF) and dengue shock syndrome. Patient concerns: A 15-year-old male presented with fever and petechiae and later developed hemoptysis. Diagnosis: Dengue fever with DHF with diffuse alveolar hemorrhage. Interventions: Invasive ventilation with high positive end expiratory pressure, multiple transfusions of packed red blood cells, fresh frozen plasma, single donor platelets and inotropic support Outcomes: The patient was stabilized and discharged on minimal supplemental oxygen. Lessons: Diffuse alveolar hemorrhage, although very rare, should be considered in a patient with dengue who presents with hemoptysis. The treatment is directed at providing respiratory and circulatory support, and preventing the progression of microcirculation damage.

Objective: To investigate the antidiabetic activity of hydro-alcoholic extract of Adina cordifolia (Roxb.) leaves (HAEACL) in alloxan induced diabetic rats at 250 and 500 mg/kg doses. Methods:Glibenclamide (10 mg/kg, s.c.) was used as the standard which produced a significant reduction in blood glucose levels. The blood glucose levels of experimental animals were determined at 0, 2, 4 and 6 h after treatment with the plant extract by using glu-oxidase peroxidise reactive strips and glucometer. Results: Treatment with HAEACL at 500 mg/kg dose decreased the blood glucose level significantly. However, the lower doses (250 mg/kg) of HAEACL produced a little decrease in blood glucose level. It showed that there was a dose dependent decrease in blood glucose level in the alloxan induced diabetic rats as compared to the control group. Conclusions: The present study shows that HAEACL possessed significant antidiabetic activity.
