Forty-three cases of diabetic ketosis were analysed to determine the mode of presentation, treatment modalities and outcome. Among these cases 62.8% were non-insulin dependent diabetes mellitus (NIDDM) patients and 37.2% belonged to the insulin dependent diabetes mellitus (IDDM) group. Six patients had blood glucose levels of more than 250 mg/dl but less than 300 mg/dl who were grouped separately for analysis under the term "euglycaemic diabetic ketoacidosis (EGDK)". Infection was the commonest precipitating factor in diabetic ketosis in all groups. Abdominal pain and vomiting occurred with NIDDM and EGDK cases. Drowsiness was common and coma was rare. Acute myocardial infarction (MI) and pulmonary oedema occurred with NIDDM cases. Shock, acidosis, acquired respiratory distress syndrome (ARDS) and mucor mycosis were seen with IDDM cases. Mortality was 7 out of 43(16.3%). Saline requirement was lower in NIDDM and EGDK cases. Intensive insulin therapy with hourly intravenous doses were needed for IDDM cases while majority of NIDDM cases could be managed with 6 hourly doses of insulin given subcutaneously or intramuscularly.

Approximately 400 cases of Hantavirus Pulmonary Syndrome (HPS) have been reported on the North American continent since the first epidemic in 1993, in New Mexico, USA. In Brazil, 12 cases were confirmed before 1998. Infection results from inhalation of rodent blood, saliva or waste. Clinical findings of the disease are characterized by a nonspecific febrile illness, followed by rapid progression to pulmonary edema which may lead to a shock-like state or renal failure. Mortality is high and emergency measures are necessary, including ECMO (extracorporeal membrane oxygenation) in those patients with cardiopulmonary failure. Each virus strain is carried by a specific species of rodent. This leads to an overlapping geographic distribution of the rodent and virus. Public health authorities emphasize prevention of the disease. Guidelines have been prepared by the CDC (Centers for Disease Control) for use by Latin American countries. Vaccines against hantavirus are under development and clinical trails are ongoing in Korea, China and the United States.

Infection with a newly described endotheliotropic adenovirus was the cause of a 1993 epizootic reminiscent of hemorrhagic disease in California mule deer (Odocoileus hemionus columbianus and O. hemionus hemionus). Pulmonary edema and intestinal luminal hemorrhage, or necrotizing stomatitis associated with systemic or localized vasculitis, respectively, were common lesions seen in animals that died during the epizootic. In order to determine if white-tailed deer (Odocoileus virginianus) also are susceptible to infection and fatal disease with the deer adenovirus, eight white-tailed deer fawns (4- to 6-mo-old) were inoculated with purified deer adenovirus. Four were inoculated intravenously and four were inoculated through the mucous membranes. Seven days post-inoculation, one of the fawns inoculated intravenously died. Pulmonary edema and hemorrhagic enteropathy were associated with pulmonary and intestinal vasculitis with systemic multiorgan distribution of endotheliotropic adenovirus as demonstrated by transmission electron microscopy and immunohistochemistry. Adenovirus was reisolated from lung homogenates of the fawn that died of adenovirus hemorrhagic disease.

Pleuropulmonary amebiasis is the common and pericardial amebiasis the rare form of thoracic amebiasis. Low socioeconomic conditions, malnutrition, chronic alcoholism, and ASD with left to right shunt are contributing factors to the development of pulmonary amebiasis. Although no age is exempt, it commonly occurs in patients aged 20 to 40 years, with an adult male to female ratio of 10:1. Children rarely develop thoracic amebiasis: when it does occur there is an equal sex distribution. The infection usually spreads to the lungs by extension of an amebic liver abscess. Infection may pass to the thorax directly from the primary intestinal lesion through hematogenous spread, however. Lymphatic spread is one possible route. Inhalation of dust containing cysts and aspiration of cysts or trophozoites of E histolytica in the lungs are some other hypothetical routes. The lung is the second most common extraintestinal site of amebic involvement after the liver. Usually the lower lobe, and sometimes the middle lobe of the right lung, are affected, but it may affect any lobe of the lungs. The patient develops fever and right upper quadrant pain that is referred to the tip of the right shoulder or in between the scapula. Hemophtysis is common. The diagnosis of thoracic amebiasis is suggested by the combination of an elevated hemidiaphragm (usually right), hepatomegaly, pleural effusion, and involvement of the right lung base in the form of haziness and obliteration of costophrenic and costodiaphragmatic angles. Infection is usually extended to the thorax by perforation of a hepatic abscess through the diaphragm and across an obliterated pleural space, producing pulmonary consolidation, abscesses, or broncho-hepatic fistula. Empyema develops when a liver abscess ruptures into the pleural space. Rarely, a posterior amebic liver abscess can burst into the inferior vena cava and develop an embolism of the inferior vena cava and thromboembolic disease of the lungs with congestive cardiac failure or corpulmonale. Diagnosis by finding E histolytica in stool specimens is of limited value. In a limited number of cases amebae might be found in aspirated pus or expectorated sputum. "Anchovy sauce-like" pus or sputum may be found. Presence of bile in sputum indicates that the pus is of liver origin. Serological tests are of immense value in diagnosis. Liver enzymes are usually normal and neutrophilic leucocytosis may or may not be found. ESR is invariably elevated. Anti-amebic antibodies can be detected by ELISA, IFAT, and IHA. Amebic antigen can be detected from serum and pus by ELISA. Detection of Entamoeba DNA in pus or sputum may be a sensitive and specific method. Pleuropulmonary amebiasis is easily confused with other illnesses and is treated as pulmonary TB, bacterial lung abscesses, and carcinoma of the lung. A single drug regimen with metronidazole with supportive therapy usually cures patients without residual anomalies. Aspiration of pus from empyema thoracis may be needed for confirmation and therapeutic purposes. The pericardium is usually involved by direct extension from the amebic abscess of the left lobe of the liver, sometimes from the right lobe of the liver, and rarely from the lungs or pleura. An initial accumulation of serous fluid due to reactive pericarditis followed by intrapericardial rupture may develop either (1) acute onset of severe symptoms with chest pain, dyspnea, and cardiac tamponade, shock, and death, or (2) progressive effusion with thoracic cage pain, progressive dyspnea, and fever. Chest radiograph, ultrasound examination, and CT scan usually confirm the presence of a liver abscess in continuity with the pericardium and fluid within the pericardial sac with or without the fistulous tract. Echocardiography may demonstrate fluid in the pericardial cavity. Patients should be cared for in the ICU and ambecides should be started without delay. Pericardiocentesis usually confirms the diagnosis and improves the general condition of the patient. Aspiration of the accumulated fluid should be performed urgently in cardiac tamponade; repeated aspiration may be needed. Surgical drainage should be done if needed. Acanthamoeba, a free-living ameba, may also infect the lungs in the form of pulmonary nodular infiltration and pulmonary edema in association with amebic meningoencephalitis in immunocompromised patients. It usually spreads to the meninges of the brain by way of the blood from its primary lesion in the lung or skin. Early diagnosis and institution of treatment may be life saving for these patients. A literature review shows that HIV/AIDS patients are not prone to infection with E histolytica. It is now clear that there are an increasing number of HIV-seropositive patients among amebic liver abscess patients, however, which suggests that although the incidence of intestinal infection is not high among HIV-seropositive or AIDS patients they are more susceptible to an invasive form of the disease.

Malaria in pregnancy is one of the most important preventable causes of low birthweight deliveries worldwide. It is also a major cause of severe maternal anaemia contributing to maternal mortality. It is estimated that 40% of the world's pregnant women are exposed to malaria infection during pregnancy. The clinical features of Plasmodium falciparum malaria in pregnancy depend to a large extent on the immune status of the woman, which in turn is determined by her previous exposure to malaria. In pregnant women with little or no pre-existing immunity, such as women from non-endemic areas or travellers to malarious areas, infection is associated with high risks of severe disease with maternal and perinatal mortality. Women are at particular risk of cerebral malaria, hypoglycaemia, pulmonary oedema and severe haemolytic anaemia. Fetal and perinatal loss has been documented to be as high as 60-70% in non-immune women with malaria. Adults who are long-term residents of areas of moderate or high malaria transmission, including large parts of sub-Saharan Africa, usually have a high level of immunity to malaria. Infection is frequently asymptomatic and severe disease is uncommon. During pregnancy this immunity to malaria is altered. Infection is still frequently asymptomatic, so may go unsuspected and undetected, but is associated with placental parasitization. Malaria in pregnancy is a common cause of severe maternal anaemia and low birthweight babies, these complications being more common in primigravidae than multigravidae. Preventative strategies include regular chemoprophylaxis, intermittent preventative treatment with antimalarials and insecticide-treated bednets.

The performance of pathological findings as a diagnostic tool for the detection of classical swine fever (CSF) outbreaks during the 1997/1998 CSF-epidemic in The Netherlands was evaluated by constructing and analysing receiver operating characteristic (ROC) curves. This was done at the individual pig level and at the submission level (a group of pigs from the same herd submitted together for post-mortem investigation). At post-mortem examination, the tonsils, spleen, ileo-caecal valve and renal pelvis were sampled, sent to the reference laboratory, and tested by means of a CSF-specific fluorescent antibody test in combination with a confirmatory test. This resulted in an infection status at the individual pig level. The infection status and pathological findings of 1072 individual pigs from a total of 230 infected herds were included in this analysis. We also included submissions of pigs from herds that were sent to post-mortem examination because of a clinically CSF-suspect situation but afterwards were concluded to be from non-infected herds. Infection status and pathological findings of 1224 individual pigs from a total of 241 non-infected herds were included in the analysis. Pneumonia, pleuritis, chronic bronchitis, pulmonary oedema, chronic gastric ulceration, dry faecal contents in the colon, conjunctivitis, haemorrhages in the renal pelvis, renal haemorrhages, splenic enlargement, haemorrhages in the urinary bladder, haemorrhagic and enlarged lymph nodes were the most frequently recorded pathological findings during a post-mortem examination of pigs submitted in a CSF-suspect clinical situation. However, some of these pathological findings (e.g. pneumonia, pleuritis) were almost evenly distributed in infected and in non-infected pigs, resulting in a high sensitivity combined with a low specificity. The area under the ROC curve of pathological findings at the individual pig level and at the submission level was 0.720 and 0.782, respectively, which was significantly (P<0.0001) larger than the area under the random ROC curve. It was concluded that, although gross pathology is a legitimate test, its quantitative contribution to the detection of CSF is limited.

Acute respiratory distress (ARD) in two nonimmune adults with imported mixed and vivax malarial infections with low and resolving parasite load is described. Malarial pulmonary edema exacerbated by hypoalbuminemia and fluid redistribution without overload occurred in the latter patient. ARD led to mortality in one of the two. ARD should be promptly recognized and managed.

Enterovirus 71 (EV71) is one of the main causative agents of hand, foot and mouth disease (HFMD) in young children. Infections caused by EV71 could lead to many complications, ranging from brainstem encephalitis to pulmonary oedema, resulting in high mortality. Thus, rapid detection of the virus is required to enable measures to be implemented in preventing widespread transmission. Based on primers and probes targeting at the VP1 region, a real-time reverse-transcriptase polymerase chain reaction (RT-PCR) hybridization probe assay was developed for specific detection of EV71 from clinical specimens. Quantitative analysis showed that the assay was able to detect as low as 5 EV71 viral copies and EV71 was detected from 46 of the 55 clinical specimens obtained from pediatric patients suffering from HFMD during the period from 2000 to 2003 in Singapore. This study showed that the single tube real-time RT-PCR assay developed in this study can be applied as a rapid and sensitive method for specific detection of EV71 directly from clinical specimens.

In 1998, an epidemic of enterovirus 71 (EV 71) infection occurred in Taiwan. The purpose of this study was to assess the epidemiology of EV 71 infection in Taiwan. Between March 1998 and December 2005, a total of 1,548 severe cases of hand-foot-mouth disease and herpangina (HFMD/HA) was reported to the Center for Disease Control in Taiwan. A seasonal variation in number of severe cases was observed, with the annual peak in second quarter. Deaths from severe HFMD/HA varied from year to year (chi(2) for trend = 6.781, P = 0.009). Most (92%) cases occurred in children </= 4 years of age. Children infected with EV 71 had higher risk of pulmonary edema/hemorrhage and encephalitis than those not infected. Infection with EV 71 has emerged as an important infectious disease causing serious clinical illness and deaths of young children. Vaccine development is recommended to prevent future EV 71 infections.

Pulmonary edema is a recognized complication of Plasmodium falciparum malaria but is uncommon with Plasmodium vivax infection. We report the case of a non-immune adult with imported P. vivax malaria who developed pulmonary edema during treatment. The case was further complicated by a recurrent malaria episode after failure of acute quinine and doxycycline treatment followed by terminal primaquine therapy. Prompt recognition and appropriate management of pulmonary edema is needed for optimal outcomes of P. vivax infection, as well as awareness of the potential failure of terminal therapy for liver hypnozoites.
