Children with dengue fever presenting to the Institute of Social Pediatrics, Government Stanley Hospital, during the months of October to December 2001, were prospectively followed up for clinical profile and outcome. Commonest clinical features were fever, vomiting, bleeding, body pain and hepatomegaly. Elevated liver enzymes and low platelet counts were common laboratory findings in dengue. Hepatomegaly, positive tourniquet test, elevated haematocrit and thrombocytopenia were more common in DHF and DSS group. Retro-orbital pain was slightly more in DHF and DSS groups and there was a tendency for DSS to present at an earlier age. There was no correlation between platelet counts and bleeding in classical dengue cases.

In Bucaramanga, Colombia, dengue haemorrhagic fever (DHF) has become endemo-epidemic since 1992. A cross-sectional study covering a period of 10 years (February, 1992 to February, 2002) was undertaken in children under 13 years of age hospitalized at the University Hospital. Observations were recorded on the clinical features, laboratory tests and the natural development of the disease. A total of 763 patients were examined, of whom 617 were classified as having DHF according to the WHO criteria (9.1% Grade I, 61.5% Grade II, 21.7% Grade III and 7.5% Grade IV). One hundred forty six patients could not be classified. The highest incidence took place in 1997, 1998 and 2001. Seventy four per cent of patients came from the metropolitan area of Bucaramanga; 48% were males; 0.3%, newborns; 11.8%, infants; 23%, pre-school children, and 64.9%, school children. The most important clinical features were fever and haemorrhagic manifestations (100%); vomiting (60%); abdominal pain (57%); headache (50%); osteomyalgia (40.8%); hepatomegaly (33%), and macular rash (29%). Among the haemorrhagic manifestations we found petechiae (56%); positive tourniquet test (35%); gastrointestinal bleeding (34%), and epistaxis (32%). Serous effusion was found in 17.7% of cases. Alarm signs of shock were found in 29%. Fifty two per cent had leucopenia and 37.3% atypic lymphocytes. Among other unusual manifestations were hepatitis, encephalopathy, alithiasic cholecystitis, acute renal failure, haemophagocytic syndrome and coinfections. Of the 617 cases, 12 died (1.5%).

Extreme plasmacytosis in peripheral blood is a rare finding most often associated with plasma cell leukemia but rarely with other malignancies, infectious diseases, or drug reactions. We report the case of a 40-year-old man who was a US expatriate working and traveling in East Asia. He presented with complaints of fever, myalgia, headache, vomiting, and diarrhea of 3 days' duration. An initial evaluation revealed elevated liver function tests, thrombocytopenia (68 x 10(3)/microL), and a white blood cell count of 5.8 x 10(3)/microL with 19% plasma cells (1100/microL), 9% abnormal plasmacytoid lymphocytes (520/microL), 37% polymorphonuclear leukocytes, 3% band forms, 27% lymphocytes, 4% monocytes, and 1% eosinophils. An extensive evaluation was performed, including infectious disease serologies, a bone marrow biopsy, and flow cytometry. During the course of 3 days, his symptoms and hematologic findings improved dramatically. Serologic results were reactive for dengue (immunoglobulin M [IgM] positive, reciprocal IgG titer, 655 360), consistent with a secondary infection of unknown serotype. He remains well 4 years later. To our knowledge, plasmacytosis to this degree has not been described in dengue fever, but atypical lymphocytosis is common. In patients from dengue-endemic areas, even extreme plasmacytosis should be assessed to determine whether it is transient and related to an acute illness before proceeding to an extensive evaluation.

Between January and June 1995, an outbreak of dengue fever occurred in Palau, an island nation of 32,000 inhabitants in the Western Pacific. To determine the magnitude of this outbreak and to determine modifiable risk factors to guide control strategies, we established active surveillance at the national hospital and private clinics, reviewed available clinical records, and conducted serologic and entomologic surveys. Between January 1 and July 1, 1995, 817 case-patients with acute febrile illness with body or joint aches and one of the following: headache, rash, nausea, vomiting, or hemorrhagic manifestations presented to health facilities in Palau. The epidemic peaked in the second week of April 1995. Of 338 case-patients tested, 254 (75%) had positive serologic results by an IgM capture enzyme-linked immunosorbent assay. Dengue 4 virus was isolated from 78 (51%) of 154 serum samples tested. Blood samples collected during a cross-sectional survey were tested for IgM antibody and yielded an attack ratio of 27% (95% confidence interval = 23-31%). Potential vectors included the introduced species Aedes aegypti and Ae. albopictus, and the native species Ae. hensilli. Significant risk factors (P < or = 0.05) for infection included age < 20 years, the presence of food or water pans for animals on the property, taro farming, the presence of Ae. aegypti on the property, and presence of Ae. scutellaris group mosquitoes (Ae. Hensilli, Ae. albopictus, and a native species). This was the first outbreak of dengue 4 virus in the Western Pacific, and the first documented epidemic of dengue in Palau since 1988.

This paper describes a model for predicting hemoglobin (Hb) by using bioelectrical impedance analysis (BIA) in dengue patients in the Hospital Universiti Kebangsaan Malaysia (HUKM). Bioelectrical impedance measurements were conducted on 83 (47 males and 36 females) serologically confirmed dengue fever (DF) and dengue hemorrhagic fever (DHF) patients during their hospitalization. The predictive equation for Hb was derived using multivariate analysis. We investigated all the parameters in BIA, patients' symptom and demographic data. In this developed model, four predictors (reactance (XC), sex, weight and vomiting) were found to be the best predictive factors for modeling Hb in dengue patients. However, the model can only explain approximately 42% of the variation in Hb status, thus single frequency bio-impedance stand-alone technique is insufficient to monitor Hb for the DF and DHF patients. Further investigation using multi-frequency BIA is recommended in modeling Hb to achieve the most parsimonious model.

Dengue infection is a major public health problem, affecting the general population in Southeast Asia. Hematologic aberrations in dengue infection include atypical lymphocytosis, coagulopathy, and predominant thrombocytopenia. Bleeding and other presentations in 30 Thai patients with dengue infection during an endemic season (2003) are presented. A review of the clinical presentation of these patients was performed. All had fever as a chief complaint. The three most common complaints were fever (100%), vomiting (90%), and cough (90%), respectively. Concerning bleeding, only eight cases (26.6%) had signs of bleeding. Those manifestations included petechiae (seven cases, 23.3%) and melena (one case, 3.3%). Skin bleeding (petechiae) due to thrombocytopenia is the most common bleeding manifestation in dengue infection. However, physicians should not overlook bleeding from other less common sites such as the gastrointestinal tract and genitourinary tract.

An alarming rise of dengue has been seen in Mumbai during the post-monsoon season. We undertook this prospective study in the pediatric wards and pediatric intensive care unit of B. J. Wadia Hospital for Children between 27 August 2003 and 10 October 2003 to determine the clinical features, laboratory abnormalities, and outcome of children affected with dengue and to determine the predictive markers for dengue shock syndrome. Fifty-one suspected dengue cases were tested for positivity of dengue by determination of dengue IgM antibodies by ELISA test. These positive cases were analysed for common clinical features, laboratory derangements, and outcome. Patients were subdivided into three subgroups: dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS) as per WHO classification. Predictive markers for DSS were also determined. Thirty-nine patients had a positive dengue IgM titre, 20 patients had DHF, 18 patients had DSS, and one patient had DF The mean age of presentation was 4.9 years. Fever, hepatomegaly, vomiting, bleeding tendencies, erythematous rash, thrombocytopenia, elevated liver enzymes, and deranged PT and PTT were the predominant clinical and laboratory features. Predictive markers for DSS were younger age at onset, altered sensorium, paralytic ileus, and significantly deranged PT. Patients with DSS also had a longer recovery period and required more supportive management in the form of component therapy and ionotropic support. All three patients who died belonged to the DSS subgroup with case fatality rate for DSS being 16.6 per cent. None of the patients in the DHF or DF subgroup died. Endemicity of dengue fever is on the rise in Mumbai with increased incidence among children. Appropriate investigations, strict monitoring and prompt supportive management can reduce mortality in dengue. Predictive markers of DSS can reduce the mortality if promptly treated. Also prevention of transmission by mosquito control and maintaining water sanitation is required to effectively control this epidemic.

Dengue fever is an acute febrile viral disease, which frequently presents with high fever, headache, bone pain and skin rash. Acute pancreatitis and seizure are rare manifestations of dengue virus infection. A 66-year-old woman with diabetes mellitus presented with epigastralgia, nausea, vomiting, diarrhea and fever. Acute pancreatitis, abnormal liver function and thrombocytopenia were diagnosed at a local hospital. After persistent fever, thrombocytopenia and seizure developed she was transferred to our medical center. Dengue virus infection was confirmed by serology study and dengue hemorrhagic fever grade II was diagnosed. No further neurological symptoms occurred and pancreatitis improved gradually after supportive care. She recovered and had no sequelae at 1 year follow-up. Acute pancreatitis and seizure may be manifestations of dengue virus infection, especially in patients with delayed diagnosis, prolonged fever and thrombocytopenia.

Dengue fever is the world's most important viral hemorrhagic fever disease, the most geographically wide-spread of the arthropod-born viruses, and it causes a wide clinical spectrum of disease. We report a case of dengue hemorrhagic fever complicated by acute hepatitis. The initial picture of classical dengue fever was followed by painful liver enlargement, vomiting, hematemesis, epistaxis and diarrhea. Severe liver injury was detected by laboratory investigation, according to a syndromic surveillance protocol, expressed in a self-limiting pattern and the patient had a complete recovery. The serological tests for hepatitis and yellow fever viruses were negative. MAC-ELISA for dengue was positive.

A comparative study of dengue hemorrhagic fever in infants and children was conducted at the Department of Pediatrics, Phetchabun Hospital between May,1999 and December, 2002. There were 1,924 DHF patients (aged 0-14 years). There were 40 (2.1%) infants (age 0-l years) and 27 (1.4%) young children (age 1-2 years). Sixty-seven cases (3.5%) of the older children (> 2-14 years) were selected to be compared. The clinical and epidemiological data for each of the three groups were not statistically different from each other, except for age, splenomegaly, shock state and mode of dengue infection. Older children were more likely to have a second dengue infection and a shock state than younger patients. Laboratory investigation results and fluid management for each of the three groups were not significantly different from each other except for the total WBC (min), neutrophils (max), lymphocytes (max) and platelets (min). The platelets (min) in the infants were significantly lower than in the younger children and the older children. Associated symptoms, diseases, complications, and hematologic manifestations in each of the three groups were not significantly different from each other except for the presence of coryza, seizures, nausea/vomiting, rash, and petichiae. Coryza, seizures, nausea/vomiting, rash, and petichiae in the infants and younger children were significantly different from the older children.
