A dengue outbreak occurred in Kaohsiung City starting in July in 2001. We studied the clinical profile of all patients admitted to Kaohsiung Veterans General Hospital during this outbreak from July 2001 to January 2002. A total of 25 cases of clinically suspected dengue fever were treated during this period, and 13 of them were confirmed by laboratory results (13/25; 52%). Eleven of the 25 patients (11/25; 44%) were admitted. The mean age of the patients with laboratory confirmation of infection was 53 years (range, 7 to 85 years). Headache (7/13; 53.8%), bone pain (8/13; 61.5%), myalgia (10/13; 76.9%), abdominal pain (7/13; 53.8%), and skin rash (9/13; 69.2%) were the most common presentations. A high proportion of patients were classified as having dengue hemorrhagic fever (DHF) [6/13; 46.2%] and 2 of these patients had dengue shock syndrome (DSS) based on the World Health Organization criteria. Pretibial petechia (6/13; 46.1%), gastrointestinal bleeding (6/13; 46.1%), and hemoptysis (4/13; 30.8%) were the most common hemorrhagic manifestations. The average hospital stay was 7.1 days. Thrombocytopenia was very common and 84.6% patients had a platelet count less than 100,000/mm3. Monocytosis was found in all patients. Few patients required blood or platelet concentrate transfusion. The 2 patients who developed DSS both survived. All patients recovered completely without any obvious sequela. In conclusion, there was a high percentage of DHF among patients in the dengue outbreak in 2001. Increasing rates of DHF compared to previous reports from Taiwan may be a sign of hyperendemicity (multiple serotypes present) of the dengue virus in Kaohsiung City and its greater likelihood elsewhere in Taiwan. Prevention and control of both dengue fever and DHF have thus become increasingly important.

Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic disease with a high mortality rate causing viral hemorrhagic fever. We studies the respiratory system findings, demographics, clinical and laboratory findings of patients with CCHF admitted to our hospital. In this retrospective study we evaluated 108 patients with CCHF confirmed by laboratory findings. The charts of all hospitalized patients were reviewed, and the age, sex, occupation, city of residence, history of tick bite or of removing a tick, smoking history, chest X-ray results, outcome and clinical and laboratory findings were recorded for each patient. Sixty of the chest radiographs were read as normal, 33 were read as showing unilateral pathology and 15 showed bilateral pathology. Seven of the 108 patients died due to severe pulmonary infection and hemorrhage. The frequency of pathological chest radiographs was higher among the CCHF patients who died than among the survivors, but the difference was not significant. Pulmonary parenchyma hemorrhage can occur in CCHF patients with hemoptysis, dyspnea, chest pain and infiltration on chest radiographs and may lead to morality.

In present study 890 serum samples suspected of dengue fever on clinical grounds were received in department of Microbiology. Out of these 249 cases showed thrombocytopenia (platelet count < 1 lakh/cumm) and were subjected to rapid dengue serological test as well as IgM capture ELISA. 11(4%) cases were diagnosed as primary dengue infection (only IgM positive) by rapid dengue IgG/IgM bispot immunocomb test. There were 123(49%) cases with only IgG positive suggesting secondary/past dengue infection. Both IgM and IgG were seen in 24(10%) cases. Number of cases negative for both IgM and IgG were 91(37%). IgM positive cases were confirmed by IgM capture ELISA. Classical dengue fever (DF) was noted in 168 (67%) patients and dengue hemorrhagic fever (DHF) in 81(33%) cases. Common clinical presentations of DHF were fever 78 (96%), body-ache 74 (91%), arthralgia 74 (91%), retro-orbital pain 65 (80%), abdominal pain 07 (09%). Bleeding manifestation were in the form of petechiae, melena, epistaxis, hematuria, hemoptysis, hematemesis, bleeding gums and conjunctival hemorrhages. Out of 81 DHS patients 13 (16%) patients had platelet count between 50,000 and 1 lakh. 68 (84%) patients had platelet count below 50,000. Majority of these patients 47 (58%) had platelet below 20000 and were IgG positive. Thrombocytopenia correlated well with bleeding manifestations in our patients. In an epidemic setting if the patients present with fever, vomiting, musculoskeletal pain and bleeding along with low platelet count a strong possibility of DHF/DSS should be kept.

During a dengue outbreak in 2005 in the East-coast region of Peninsular Malaysia, one of the worst hit areas in the country at that time, we undertook a prospective study. We aimed to describe the bleeding outcome and changes in the liver and hematologic profiles that were associated with major bleeding outcome during the outbreak. All suspected cases of dengue admitted into the only referral hospital in the region during the outbreak were screened for WHO 2002 criteria and serology. Liver function, hematologic profile and severity of bleeding outcome were carefully documented. The association between symptoms, liver and hematologic impairments with the type of dengue infection (classical vs. hemorrhagic) and bleeding outcome (major vs. non-major) was tested. Dengue fever was confirmed in 183 cases (12.5/100,000 population) and 144 cases were analysed. 59.7% were dengue hemorrhagic fever, 3.5% were dengue shock syndrome and there were 3 in-hospital deaths. Major bleeding outcome (gastrointestinal bleeding, intracranial bleeding or haemoptysis) was present in 14.6%. Elevated AST, ALT and bilirubin were associated with increasing severity of bleeding outcome (all P < 0.05). Platelet count and albumin level were inversely associated with increasing severity of bleeding outcome (both P < 0.001). With multivariable analysis, dengue hemorrhagic fever was more likely in the presence of abdominal pain (OR 1.1, 95% CI 0.02- 1.6) and elevated AST (OR 1.0, 95% CI 1.0-1.1) but the presence of pleural effusion (OR 5.8, 95% CI: 1.1-29.9) and elevated AST (OR 1.008, 95% CI: 1.005-1.01) predicted a severe bleeding outcome. As a conclusion, the common presence of a severe hemorrhagic form of dengue fever may explain the rising death toll in recent outbreaks and the worst impairment in liver and hematologic profiles was seen in major bleeding outcome.

Dengue fever is an arboviral disease transmitted to humans through the bites of infected female Aedes mosquitoes. Dengue virus is a member of the Flaviviridae family, and human infection can be caused by any of the four antigenically distinct serotypes (DENV 1-4). The infection has become recognized as the most important and prevalent arboviral disease in humans, endemic in almost 100 countries worldwide. Nearly 3 billion people live in areas with transmission risk. Autochthonous transmission of the virus in previously disease-free areas, increased incidence in endemic areas, and epidemic resurgence in controlled regions could increase the risk of contracting more severe forms of the disease, such as dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS). Symptomatic dengue virus infection can present with a wide range of clinical manifestations, from mild fever to life-threatening DSS. Thoracic complications may manifest as pleural effusion, pneumonitis, non-cardiogenic pulmonary edema, and hemorrhage/hemoptysis. No vaccine is currently available and no specific treatment for dengue fever exists, but prevention and prompt management of complications in patients with DHF can help reduce mortality. This review describes the main clinical, pathological, and imaging findings of thoracic involvement in DHF.
