Dengue is an arthropod-borne viral disease whose frequency has increased steadily in the Americas over the past 25 years. The type of dengue that carries the highest mortality is the clinical variant known as dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS). Even though no vaccine or drug against the disease is available, successful management consists of preventing serious illness through patient follow-up and monitoring danger signals so as to be able to initiate aggressive intravenous rehydration and prevent shock or treat it early and successfully. These measures are also useful in preventing other complications, such as massive hemorrhage, disseminated intravascular coagulation, multiple organ failure, and respiratory failure due to non-cardiogenic pulmonary edema. Primary health care (PHC) settings and the community are ideal spaces for this type of preventive management based on health education and active case detection. It involves training all medical and nursing staff, students, and community health workers, as well as reorganizing health care in PHC units and hospitals and redistributing available resources during a dengue epidemic.

A 36-year-old woman, who had given birth once before, had an eclamptic epileptic seizure eight days after caesarean delivery of healthy premature twins. Severe headache and loss of vision, leading to blindness, had not been recognised as prodromal signs by the healthcare professionals involved. Thereafter, she suffered a generalised epileptic seizure with tongue bite. She recovered fully after treatment with magnesium sulphate and nifedipine. Eclampsia is a severe condition with high rates of maternal complications, such as abruptio placentae, disseminated intravascular coagulation, neurological problems, pulmonary oedema, acute renal insufficiency and even death. Recognition of prodromal symptoms like headache, visual disturbances and upper abdominal pain is of the utmost importance. Magnesium sulphate intravenously is the treatment of choice. About 25% of the cases of postpartum eclampsia develop 2-28 days after delivery. A history of pre-eclampsia before or during the delivery is often absent. There is a relative increase in the incidence of late postpartum eclampsia, possibly because of misinterpretation ofprodromal symptoms, as illustrated by this case report. Every physician should be able to recognise the symptoms of pre-eclampsia and be aware of the possible consequences.

In response to questions about the safety of ephedra-based dietary products, ephedra-free products are now available. Many contain synephrine, a sympathomimetic amine with structural similarities to ephedra. We present a 22-year-old, previously healthy, African American male with sickle cell trait who developed rhabdomyolysis after ingestion of a synephrine-containing dietary supplement. The patient developed fatigue, dehydration, and myalgias while exercising. He developed severe rhabdomyolysis, with a peak creatine phosphokinase level of 2.8 million U/L, complicated by pulmonary edema, acute renal failure, disseminated intravascular coagulation, and bilateral compartment syndromes in his lower extremities. He required prolonged hospitalization for hemodialysis, multiple wound debridements, hyperbaric oxygen therapy, and physical therapy. He has permanent sensory and motor neurological deficits in his distal lower extremities. Military physicians should routinely inquire about the use of dietary supplements, educate patients about the potential adverse reactions associated with these agents, and encourage healthy diets and exercise for weight loss.

Three pregnant women with diagnosis of HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets), received emergency cesarean section in our hospital. Considering low platelet counts, in all three patients, operations were performed under general anesthesia using sevoflurane without epidural or spinal anesthesia. Special attention was paid to management of blood pressure, especially intra-operative hypertension. Moreover, if necessary, platelet and fresh frozen plasma were transfused, and therapy to prevent disseminated intravascular coagulation (DIC) and to protect liver and renal function, was performed perioperatively. As a result, laboratory data of all three patients recovered to almost within normal ranges after operation, and they were discharged without untoward complications. HELLP syndrome is a severe complication of pregnancy. Complications of this syndrome were severe including acute renal failure, DIC, pulmonary edema, cerebral hemorrhage and liver rupture. It is reported that maternal mortality is 2-24%. In the management of pregnant women complicated with HELLP syndrome, early diagnosis and adequate therapy, including preventive therapy for complications, are necessary.

Acute pancreatitis represents a spectrum of disease, ranging from a mild, transitory illness to a severe, rapidly progressive hemorrhagic form, with massive necrosis and mortality rates of up to 24%. The reported incidence of acute pancreatitis diagnosed first at clinicopathologic autopsy ranges between 30% and 42%. To better describe outpatient fatalities due to acute pancreatitis that present as sudden, unexpected death, we retrospectively reviewed the autopsy files at the Institute of Legal Medicine, University of Hamburg, Germany, from 2000-2004. Individual cases were analyzed for sex, age, race, circumstances of death, social background of the deceased and previous medical history, seasonal occurrence of the disease, blood alcohol concentration at the time of death, body mass index, autopsy findings, histopathology, and etiology of acute pancreatitis. Among the 6178 autopsies carried out during the 5-year period evaluated, there were 27 cases of acute pancreatitis that presented as sudden, unexpected death. In all cases, the diagnosis was first made at autopsy. The male:female ratio was 1.7:1 and the mean age was 52 years (range, 30-91 years). Etiologies of acute pancreatitis included alcohol (n=19), gall stones (n=2), other identified etiologic factors (n=3), and idiopathic (n=3). Complications of acute pancreatitis included lung edema and/or acute respiratory distress syndrome, peritonitis, disseminated intravascular coagulation, and sepsis. At least 20 subjects (74%) had lived isolated, with no social contacts. Contrary to the clinical observations of a clear seasonal variation in the onset of acute pancreatitis, we found no correlation between death due to acute pancreatitis and a specific month or season. Many prior studies have suggested that the majority of deaths in severe acute pancreatitis occur in the late phase of the disease as a result of pancreatic sepsis. Conversely, in the present study, the majority of affected individuals died during the very early phase of the disease. While gallstones represent the main etiologic factor in most larger clinical series, biliary etiology seems to play only a minor role in outpatient deaths undergoing medicolegal autopsies. Data derived from medicolegal autopsy studies should be included in future population-based studies of acute pancreatitis.

Fatal complications of Plasmodium falciparum malaria have been reported. However, complicated P. vivax malaria is rare. We observed two unusual cases of P. vivax malaria who presented with clinical pictures of toxic shock. Both showed disseminated intravascular coagulation with marked thrombocytopenia, oliguric renal failure, and pulmonary edema. Examination of initial blood smears showed a P. vivax parasitemia of 2,352/microL and 12,376/microL, respectively. The patients were treated with hydroxychloroquine and primaquine without an antibacterial agent. These cases emphasize the importance of considering the possibility of P. vivax malarial infection in patients with a clinical picture resembling toxic shock if they have a travel history to malaria-endemic areas.

The demand for donor organs continues to exceed the number of organs available for transplantation. Many reasons may account for this discrepancy, such as the lack of consent, the absence of an experienced coordinator team able to solve logistical problems, the use of strict donor criteria, and suboptimal, unstandardized critical care management of potential organ donors. This has resulted in efforts to improve the medical care delivered to potential organ donors, so as to reduce organ shortages, improve organ procurement, and promote graft survival. The physiological changes that follow brain death entail a high incidence of complications jeopardizing potentially transplantable organs. Adverse events include cardiovascular changes, endocrine and metabolic disturbances, and disruption of internal homeostasis. Brain death also upregulates the release of pro-inflammatory molecules. Recent findings support the hypothesis that a preclinical lung injury characterized by an enhanced inflammatory response is present in potential donors and may predispose recipients to an adverse clinical prognosis following lung transplantation. In clinical practice, hypotension, diabetes insipidus, relative hypothermia, and natremia are more common than disseminated intravascular coagulation, cardiac arrhythmias, pulmonary oedema, acute lung injury, and metabolic acidosis. Strategies for the management of organ donors exist and consist of the normalization of donor physiology. Management has been complicated by the recent use of ''marginal'' donors and donors of advanced age or with ''extended'' criteria. Current guidelines suggest that the priority of critical care management for potential organ donors should be shifted from a ''cerebral protective'' strategy to a multimodal strategy aimed to preserve peripheral organ function.

Management of patients with dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) requires especial care. It is based on physiological replacement therapy and fluid control. The use of blood products has its own criteria, especially during the disseminated intravascular coagulation (DIC) in the hemorrhagic phase. Monitoring bleeding manifestations and laboratory tests are needed. It has been shown that preventive transfusion does not have advantages in the treatment of this disease; on the contrary it increases the length of hospitalization and the development of pulmonary edema, among other transfusion-related risks.

Defined by the association of hemolysis, hepatic dysfunction and thrombocytopenia, the Hemolysis, Elevated Liver enzyme, Low Platelets (HELLP) syndrome can complicate preeclampsia and worsen maternal and fetal prognosis. It can be diagnosed in the immediate postpartum (30%) or in the absence of preeclampsia (10-20%). Clinical diagnosis can be difficult because there is no specific symptom. Abdominal pain or vomiting during the third trimester must lead to think about this diagnosis. Biological criteria are well defined: hemolysis by the presence of schistocytes, increased serum total bilirubin >12 mg/L or LDH >600 IU/L, hepatic dysfunction by increased transaminases and thrombocytopenia by a platelet count <100,000/microL. The evolution of those parameters is a major prognostic factor. With the HELLP syndrome, maternal morbidity is dramatically increased compared to isolated preeclampsia with complications such as eclampsia, placental abruptio, disseminated intravascular coagulation, pulmonary edema, acute renal insufficiency, subcapsular liver hematoma. The management of a HELLP syndrome requests level 3 hospital with intensive care units for neonate and mother. The treatment of this syndrome requires termination of the pregnancy as soon a possible, either by cesarean section or by vaginal delivery if cervical conditions are optimal (without any maternal or fetal complications). Before 32 weeks, a more expectative attitude could be acceptable with the prematurity permitting corticotherapy for fetal pulmonary maturation. This corticotherapy can improve temporary biological parameters but there are no proven benefits to consider improvement for long term maternal or fetal prognosis. During the postpartum, evolution is usually spontaneously favorable. Recurrences are not frequent.

From 1998 to 2008 we noticed 3 cardiac deaths in male teenagers aged 18-19 during or after physical exercise. The first was working at the site recreatively, the second was engaged in soccer recreatively and the third was professional soccer player. One felt general tiredness and was exhausted of a heavily physical effort, the other after physical exercise became septic and the third was without symptoms. One died suddenly during physical exercise at the field and two died in the hospital. At the forensic autopsy the first had bilateral bacterial pneumonia, possible high-altitude non-cardiogenic pulmonary edema and cerebral edema. The second had bilateral bacterial pneumonia, adult respiratory distress syndrome, disseminated intravascular coagulation, suprarenal bleeding, cerebral edema, hypoplastic right coronary artery and myocardial fibrosis. The third had bilateral bacterial pneumonia, fibrinous pericarditis, cerebral contusion with edema, thickenning of the left ventricle 20 mm and hypoplastic ascending aorta. In Croatia the death rate among athletes reached 0.15/ 100,000, in athletes suffered of acute pneumonia 0.28/ 100,000, in others who practice exercise recreatively 0.57/ 100,000 (p = 0.0068), in all males who practice exercise recreatively 0.75/ 100,000 (p = 0.0014). Physical exercise is contraindicated in acute respiratory tract infections. Every such case has to be treated by physician. When to start with physical training after bacterial pneumonia depends on disappearing of clinical and X-ray signs of pneumonia, normalization of erythrocite sedimentation rate and of white cell count.
