Crimean-Congo hemorrhagic fever is a tick-borne viral disease reported from more than 30 countries in Africa, Asia, South-East Europe, and the Middle East. The majority of human cases are workers in livestock industry, agriculture, slaughterhouses, and veterinary practice. Nosocomial transmission is also well described. Clinical manifestations are nonspecific and symptoms typically include high fever, headache, malaise, arthralgia, myalgia, nausea, abdominal pain, and nonbloody diarrhea. Patients may show signs of progressive hemorrhagic diathesis. Laboratory abnormalities may include anemia, leukopenia, thrombocytopenia, increased AST/ALT levels, and prolonged prothrombin, bleeding, and activated partial thromboplastin times. Diagnostic methods include antibody detection by enzyme-linked immunosorbent assay, virus isolation, antigen detection, and polymerase chain reaction. The mainstay of treatment of Crimean-Congo hemorrhagic fever is supportive, with careful maintenance of fluid and electrolyte balance, circulatory volume, and blood pressure. The Crimean-Congo hemorrhagic fever virus is susceptible to ribavirin in vitro. There is no controlled study evaluating oral versus intravenous ribavirin in treating Crimean-Congo hemorrhagic fever patients, but few studies have evaluated oral ribavirin. This article reviews the epidemiology, pathogenesis, clinical manifestations, diagnosis, treatment, prevention, and prognosis of Crimean-Congo hemorrhagic fever with a special focus on oral ribavirin as a choice of medical treatment.

Acute graft-versus-host disease (GVHD) occurs after allogeneic hematopoietic stem cell transplant and is a reaction of donor immune cells against host tissues. Activated donor T cells damage host epithelial cells after an inflammatory cascade that begins with the preparative regimen. About 35%-50% of hematopoietic stem cell transplant (HSCT) recipients will develop acute GVHD. The exact risk is dependent on the stem cell source, age of the patient, conditioning, and GVHD prophylaxis used. Given the number of transplants performed, we can expect about 5500 patients/year to develop acute GVHD. Patients can have involvement of three organs: skin (rash/dermatitis), liver (hepatitis/jaundice), and gastrointestinal tract (abdominal pain/diarrhea). One or more organs may be involved. GVHD is a clinical diagnosis that may be supported with appropriate biopsies. The reason to pursue a tissue biopsy is to help differentiate from other diagnoses which may mimic GVHD, such as viral infection (hepatitis, colitis) or drug reaction (causing skin rash). Acute GVHD is staged and graded (grade 0-IV) by the number and extent of organ involvement. Patients with grade III/IV acute GVHD tend to have a poor outcome. Generally the patient is treated by optimizing their immunosuppression and adding methylprednisolone. About 50% of patients will have a solid response to methylprednisolone. If patients progress after 3 days or are not improved after 7 days, they will get salvage (second-line) immunosuppressive therapy for which there is currently no standard-of-care. Well-organized clinical trials are imperative to better define second-line therapies for this disease. Additional management issues are attention to wound infections in skin GVHD and fluid/nutrition management in gastrointestinal GVHD. About 50% of patients with acute GVHD will eventually have manifestations of chronic GVHD.

A 13-yr-old boy developed post-transplant liver tumor. At three yrs of age, this patient underwent a histocompatible sibling donor BMT for severe aplastic anemia, after a conditioning with antithymocyte globulin and cyclophosphamide. He became a HBV carrier after BMT. Stable mixed chimerism and mild thrombocytopenia, but no active hepatitis continued. At age 13, abdominal pain was a sign of massive tumor. Extremely high levels of alpha-fetoprotein indicated the clinical diagnosis of hepatoblastoma that might be the first report as post-BMT malignancy. The necropsy specimens revealed that the tumor was recipient cell-origin and showed the histopathological features of both hepatoblastoma and hepatocellular carcinoma. Prolonged mixed chimerism and hepatitis virus infection might induce a rare oncogenesis after non-irradiated conditioning.

Sudden fatal cases of influenza B infection in a 4-year-old girl and a 2-year-old boy are presented. Both children complained of abdominal pain without respiratory, neurologic or cardiac symptoms; additionally the girl had vomiting within 2 days of death. Autopsy revealed histological changes in the respiratory system consistent with a viral infection. Influenza B infection was identified by immunohistochemistry in the girl and real-time polymerase chain reaction in the boy. Additional testing including cultures, toxicology, and screening for metabolic disorders were negative. These cases illustrate the usefulness of viral testing, especially for influenza, in the medical legal autopsy of children even when the classic respiratory symptoms of flu are lacking.

Crimean-Congo hemorrhagic fever (CCHF) is a deadly viral disease that is endemic in some parts of Pakistan. We report here the first ever case of CCHF from Abbottabad. The patient presented with abdominal pain, hematemesis and low platelets, and died within 24hours of admission. The diagnosis was confirmed by PCR for the CCHF virus. Because of the aggressive infection-control measures adopted, secondary and nosocomial spread was prevented.

A 45-year-old man with end-stage renal disease due to polycystic kidney disease was admitted to the hospital because of recurrent abdominal pain, progressive peripheral motor neuron neuropathy, and respiratory failure. The diagnosis of acute intermittent porphyria was confirmed by an elevated porphyrin concentration in the urine and the presence of an R167Q mutation in the porphobilinogen deaminase gene. Use of hydroxyzine, weight loss, and/or a mild upper respiratory viral infection might have been the provoking factor of the acute intermittent porphyria. Treatment with intravenous hemin (3 mg/kg) and a high-carbohydrate diet (3000 kcal/d) had no clinical effect. Tetraplegia and chronic respiratory insufficiency developed, and the patient needed a pacemaker because of a symptomatic sinus bradycardia due to autonomic dysfunction. The patient died 10 months after the first manifestation of acute intermittent porphyria.

To compare the clinical and laboratory characteristics and disease severity between adults and children with dengue in Taiwan in 2002, we retrospectively studied 661 serologically confirmed dengue-infected patients (606 adults and 55 children) admitted between June and December 2002 to a single medical centre. The medical charts of the patients were reviewed for demographic, clinical, laboratory and imaging information. Compared with children, adult patients were found to have: higher incidences of arthralgia (P<0.001), myalgia (P=0.002), headache (P=0.028), abdominal pain (P=0.004) and upper gastrointestinal bleeding (P=0.013); lower platelet counts (P<0.001), prothrombin time (P=0.030) and serum albumin levels (P=0.037); a higher incidence of elevated alanine aminotransferase levels (P=0.001); and a higher prevalence of dengue haemorrhagic fever (DHF) (14.4% vs. 3.6%; P=0.026). The current data showed differences in clinical manifestations and laboratory characteristics between children and adults with dengue virus infection. Notably, a higher incidence of DHF was observed in adult patients compared with children in the 2002 dengue epidemic in Taiwan.

Limited information is available on the viral etiology of influenza-like illness in southern European countries, and it is still a matter of debate whether certain symptoms can be used to distinguish among the specific viruses that cause influenza-like illness. The main objective of the present study was to identify the demographic and clinical predictors of influenza-like illness due to specific viral agents. The study, which was observational in design, was conducted in Rome and Naples, Italy. Cases of influenza-like illness were defined as individuals with fever >37.5 degrees C and at least one systemic and one respiratory symptom, recruited during the winters of 2004-2005, 2005-2006, and 2006-2007. Influenza and other respiratory viruses were identified using the polymerase chain reaction (PCR), performed on throat swabs. Basic individual information was collected using a standard form. A total of 580 persons were included in the analysis. Viral pathogens were identified in fewer than 50% of the cases. Overall, 240 viral agents were detected: 22.8% were positive for influenza viruses, 10.9% for adenoviruses, 6.0% for parainfluenza viruses, and 1.7% for respiratory syncytial virus. The month of diagnosis, and muscle and joint pain were associated with influenza virus, though the positive predictive value (PPV) was low. Abdominal pain was associated with adenovirus infection. Although the PPV of symptoms for influenza virus infection was low, especially in low activity periods, these findings may help clinicians to improve their ability to perform diagnoses.

Although an estimated 1 million persons in the United States are chronically infected with hepatitis B virus, the prevalence of hepatitis B has declined since the implementation of a national vaccination program. Hepatitis B virus is transmitted in blood and secretions. Acute infection may cause nonspecific symptoms, such as fatigue, poor appetite, nausea, vomiting, abdominal pain, low-grade fever, jaundice, and dark urine; and clinical signs, such as hepatomegaly and splenomegaly. Fewer than 5 percent of adults acutely infected with hepatitis B virus progress to chronic infection. The diagnosis of hepatitis B virus infection requires the evaluation of the patient's blood for hepatitis B surface antigen, hepatitis B surface antibody, and hepatitis B core antibody. The goals of treatment for chronic hepatitis B virus infection are to reduce inflammation of the liver and to prevent complications by suppressing viral replication. Treatment options include pegylated interferon alfa-2a administered subcutaneously or oral antiviral agents (nucleotide reverse transcriptase inhibitors). Persons with chronic hepatitis B virus infection should be monitored for disease activity with liver enzyme tests and hepatitis B virus DNA levels; considered for liver biopsy; and entered into a surveillance program for hepatocellular carcinoma.

Antrodia camphorata has been recognized to be a traditional Chinese medicine for abdominal pain, diarrhea, and to protect against hepatitis virus infection. Several ingredients derived from A. camphorata possess various pharmacological and biological activities such as antioxidant and anticancer. In this study, its ability to promote immune responses and to exhibited antileukemia activity in WEHI-3 leukemia BALB/c mice were investigated. The results indicated A. camphorata significantly prolonged the survival rate and prevented the body weight loss in leukemia mice. Four mg/kg of A. camphorata treatment significantly decreased the weight of the spleen. Both doses (2 and 4 mg/kg) of A. camphorata did not affect Mac-3 marker in leukocytes. However, the 4 mg/kg of A. camphorata decreased the levels of CD11b and both doses of treatment increased CD3 and CD19. With lipopolysaccharide stimulation, the 4 mg/kg of A. camphorata promoted the significant proliferation of leukocytes; but with concanavalin A stimulation, both doses promoted the significant proliferation of leukocytes. YAC-1 target cells were killed by NK cells from the mice after treatment with A. camphorata at 4 mg/kg in target cells at a ratio of 50:1. The percentage of macrophages with phagocyted at A. camphorata treatment increased, and these effects were in dose-dependent manners.
