During the months of September 1993 through February 1994, an outbreak of hemorrhagic fever occurred in the city of Jayapura, the provincial capital of Irian Jaya, Indonesia. Seventy-two patients (age range = 1-41 years) with suspected dengue hemorrhagic fever (DHF) were enrolled into the outbreak investigation conducted during October-November 1993. The pediatric patient population consisted of 36 individuals ages 1-12 years of age with a similar male to female ratio. From clinical histories obtained from the children diagnosed with DHF (n = 23), the predominant complaints were fever (100%), headache (96.7%), vomiting (47.8%), abdominal pain (39.1%), back/bone pain (39.1%), cough (39.1%), sore throat (21.7%), convulsions (17.4%), and eye pain (13.0%). Clinical findings of the same pediatric patients included a positive tourniquet test result (100%), thrombocytopenia (100%), hemoconcentration (100%), skin petechiae (43.5%), epistaxis (39.1%), and maculopapular rash (26%). All four of the children diagnosed with DHF grade IV had hepatomegaly, pleural effusion, ascites, cold perspiration, and confusion. Serologic data demonstrated that a majority (46 of 70, 68.7%) of the individuals assessed did not have significant levels of IgM specific for dengue viruses at the time of their admission. However, the nine successful dengue virus isolations were only from these serononreactive cases (19.6%). From the other patients assessed, 11.4% had a primary (or first exposure) serologic response to dengue virus antigen (predominantly IgM); 17.1% had a secondary (or subsequent exposure) serologic response to the same dengue antigens (predominantly IgG response) and 5.7% (four adults) had indeterminate serologic data that could not differentiate between reactivity to dengue or Japanese encephalitis virus antigen preparations. Virus culture of blood samples produced nine dengue virus isolates: DEN- 1 (2), DEN-2 (1), and DEN-3 (6). Japanese encephalitis and influenza viruses were not isolated from blood and pharyngeal specimens, respectively, from any of the patients. Thus, this first reported outbreak of DHF in Irian Jaya, Indonesia was found to be attributed to dengue viruses types 1, 2, and 3.

BACKGROUND. Little is known about the clinical presentation and epidemiology of influenza A H1N1pdm in children in developing countries. We assessed the severity of influenza A H1N1pdm in children in Nicaragua by comparing H1N1pdm cases to seasonal influenza cases in an ongoing cohort study. METHODS. The Nicaraguan Influenza Cohort Study was established in June 2007 to study the burden and seasonality of pediatric influenza in a tropical developing country. During the period from June 2007 through November 2009, a total of 4391 children aged 2-14 years participated in the cohort. We examined the attack rate of clinical influenza and assessed symptoms at first presentation in febrile patients with H1N1pdm versus those with seasonal influenza A or B. RESULTS. The estimated clinical attack rate of H1N1pdm in the cohort was 20.1%, compared to 11.7% and 15.1% for seasonal influenza A and 11.9% and 24.2% for seasonal influenza A and B in 2007 and 2008, respectively. Symptoms significantly associated with H1N1pdm cases versus seasonal influenza A cases were sore throat (adjusted odds ratio [OR], 1.7; 95% confidence interval [CI], 1.2-2.5), wheezing (OR, 5.1; 95% CI, 1.3-19.0), rhonchi (OR, 4.6; 95% CI, 1.4-15.0), crepitations (OR, 16.2; 95% CI, 2.1-128.7), pneumonia (OR, 8.0; 95% CI, 1.7-37.3), nausea (OR, 2.8; 95% CI, 1.5-5.1), and loss of appetite (OR, 2.1; 95% CI, 1.4-3.1). In addition, 3 concurrent influenza and dengue virus coinfections were identified. CONCLUSIONS. Children with influenza A H1N1pdm presented with significantly more symptoms of lower respiratory infection and gastrointestinal symptoms than children with seasonal influenza. The clinical influenza attack rate was high in both pandemic and seasonal years.

Dengue infection can be challenging to diagnose early in the course of infection before severe manifestations develop, but early diagnosis can improve patient outcomes and promote timely public health interventions. We developed age-based predictive models generated from 2 years of data from an enhanced dengue surveillance system in Puerto Rico. These models were internally validated and were able to differentiate dengue infection from other acute febrile illnesses with moderate accuracy. The accuracy of the models was greater than either the current World Health Organization case definition for dengue fever or a proposed modification to this definition, while requiring the collection of fewer data. In young children, thrombocytopenia and the absence of cough were associated with dengue infection; for adults, rash, leucopenia, and the absence of sore throat were associated with dengue infection; in all age groups, retro-orbital pain was associated with dengue infection.

Dengue fever may present with atypical manifestations. Here we report a 47 year-old male presenting with fever and sore throat for 2 days, followed by epigastric pain and tarry stool for 4 days. The esophagogastroduodenoscopy revealed multiple ulcers with a nodular margin in the duodenal bulb and second portion of the duodenum. A MRI of the abdomen revealed hemorrhagic pancreatitis, with a large intramural hematoma in the second portion of duodenum. The final diagnosis was dengue hemorrhagic fever, grade II, complicated with hemorrhagic pancreatitis and an intramural hematoma of the duodenal wall. Physicians should be aware of the atypical abdominal presentations of dengue fever.

Introduction. Dengue fever is an arboviral disease, which is transmitted by mosquito vector and presents as varied clinical spectrum of dengue fever (DF), dengue hemorrhagic fever (DHF), dengue shock syndrome (DSS), and expanded dengue syndrome (EDS) with atypical presentations, thus posing a diagnostic dilemma. Unless we are aware of these presentations, diagnosis as well as early initiation of treatment becomes difficult. We studied the various clinical presentations of dengue infection during an outbreak of disease in 2015. Materials and Methods. A total of 115 confirmed cases of dengue infection from Department of Medicine of Deen Dayal Upadhyay Hospital, New Delhi, were enrolled in this observational study. Results. The common signs and symptoms of dengue infection were fever, headache, body ache, backache, retro-orbital pain, bleeding manifestations, and rash in 100%, 87%, 86%, 58%, 41%, 21%, and 21%, respectively. Nonspecific or warning signs and symptoms included vomiting, weakness, abdominal pain, breathlessness, vertigo, sweating, and syncope. Other possible signs and symptoms of coinfections, comorbidities, or complications included diarrhea, sore throat, and neurological manifestations. There were seven patients with coinfections and four with comorbidities. The final diagnosis of these patients was DF (73%), DHF (16.5%), DSS (1.7%), and EDS (4.3%). Among EDS patients, the atypical presentations included encephalopathy, lateral rectus nerve palsy, acalculous cholecystitis, and myocarditis. Four patients required ICU care and there was no death in this study. Conclusion. Knowledge of atypical presentations is a must for early diagnosis and timely intervention to prevent life-threatening complications.

A 65-year-old previously healthy male presented to us on the fourth day of a febrile illness with headache, arthralgia, myalgia, nausea, cough, chest pain, sore throat, and passing of watery stools and dark urine with a history of exposure to leptospirosis during a dengue outbreak. On examination, there was dehydration and hypovolemia, and an ultrasound scan revealed capillary leakage. His liver transaminases, serum creatine, blood urea, C-reactive protein, and neutrophil percentage were high, and thrombocytopenia was present. Moreover, myocarditis has been detected too. Supportive therapy with intravenous ceftriaxone was administered, considering possible Weil's disease or dengue hemorrhagic fever with secondary bacterial infection. Serological tests, performed later, diagnosed him with a Rickettsia conorii infection and excluded dengue, leptospirosis, and hantavirus infections. Repeat 2D echocardiograms showed mild improvement of his cardiac failure after one month and a more improvement after eight months. Clinical features of the rickettsial spotted fever group (SFG) and leptospirosis overlap. Leptospirosis is common; thus, the risk of overlooking SFG and diagnosing leptospirosis is likely. Tests for differentiation are unavailable in Sri Lankan hospitals and in many other developing countries. Empirical doxycycline in suspected cases of SFG infections in areas where rickettsioses are prevalent can save lives as in this case.

The spectrum of dengue infection illness ranges from mildly symptomatic disease to severe forms of dengue haemorrhagic fever and dengue shock syndrome. Expanded dengue syndrome refers to unusual complications involving gastrointestinal, hepatic, neurological, pulmonary and renal systems. Subacute thyroiditis represents a very rare and under-recognised complication of dengue. We report a case of a 38-year-old female presenting with recurrent fever and throat pain following an episode of dengue. After detailed clinical examination, biochemical evaluation and imaging studies, a diagnosis of subacute thyroiditis complicating dengue was made. We discuss its clinical course and management in this report. Only four such cases have previously been reported in literature. Subacute thyroiditis may represent another rare facet of dengue expanded syndrome.
