Improvement of epidemiological situation of infectious diseases was continued in Poland in 1999. The end of epidemics of measles, pertussis, mumps, scarlatine, chickenpox, and rubella was observed. In comparison with the number of cases of infectious diseases registered in 1998, decrease in the number of notified cases of salmonellosis, dysentery, meningitis, encephalitis, and hepatitis type B and A as well as increase in the number of influenza cases and trichinosis was noticed. In 1999, compared with 1998, among all notified deaths percentage of deaths attributed to infectious diseases (0.80%) and infectious diseases death rate (7.71 per 100,000) were slightly higher as an effect of the influenza deaths increase.

Previous studies have suggested a relationship between reproductive history, pregnancy and birth factors, and the risk of neuroblastoma. We conducted a case-control telephone interview study that included a total of 504 children under the age of 19 years with newly diagnosed neuroblastoma identified by two national collaborative clinical trials groups, the Children's Cancer Group and the Pediatric Oncology Group. A total of 504 controls, matched to cases on age, were identified by random digit dialing. Conditional logistic regression was used to estimate the matched odds ratio (OR) and 95% confidence interval (CI) with adjustment for household income, and maternal race and education. In addition, case subgroups defined by age at diagnosis, tumour MYCN oncogene amplification status, and stage were evaluated. A suggestive pattern of increased risk was seen for a greater number of prior pregnancies, history of previous miscarriages and induced abortions, with nearly a twofold increase in risk for two or more prior induced abortions (OR = 1.9, 95% CI [1.0,3.7]). No association was found for the following diseases or conditions during pregnancy: hepatitis, rubella, measles, mumps, chickenpox, mononucleosis, vaccinations, morning sickness, pre-eclampsia, bleeding, proteinuria, anaemia, urinary tract infections, heart disease, kidney disease, liver disease and diabetes. A weak association was found for hypertension during pregnancy. Several labour and delivery factors were related to an increased risk, including threatened miscarriage, anaesthetic during labour (specifically epidural) and caesarean delivery. We found associations between premature delivery (<33 weeks: OR = 1.9, 95% CI [0.7,4.8]), very low birthweight (<1500 g: OR = 2.6, 95% CI [0.7,10.3]) and risk of neuroblastoma. There was no consistent pattern of increased risk found for most factors within subgroups defined by age at diagnosis, stage or MYCN status.

Baseline data on health of free-ranging wildlife is essential to evaluate impacts of habitat transformation and wildlife translocation, rehabilitation, and reintroduction programs. Health information on many species, especially great apes, is extremely limited. Between 1996 and 1998, 84 free-ranging orangutans captured for translocation, underwent a complete health evaluation. Analogous data were gathered from 60 semi-captive orangutans in Malaysia. Baseline hematology and serology; vitamin, mineral and pesticide levels; and results of health evaluations, including physical examination, provide a baseline for future monitoring. Free-ranging and semi-captive orangutans shared exposure to 11 of 47 viruses. The semi-captive orangutans had significantly higher prevalence of antibodies to adenovirus (P < 0.0005) and rota (SA 11) virus (P < 0.008). More free-ranging than semi-captive animals had antibodies to Japanese encephalitis virus (P < 0.08) and foamy virus (P = 0.05). Exposure to parainfluenza and langat viruses was detected exclusively in semi-captive animals and exposure to sinbis virus was only found in free-ranging orangutans. There was evidence of exposure to respiratory syncytial virus, coxsackie virus, dengue virus, and zika virus in both groups. Ebstein-Barr virus was ubiquitous in both groups. Prevalence of antibodies against mumps virus changed from 0% in 1996 to 45% in 1998. No antibodies were detected to many important zoonotic viral pathogens, including herpesvirus and hepatitis virus. Prevalence of Balantidium coli and Plasmodium pitheci infections and exposure to mycobacterium was higher in the semi-captive animals. Differences in exposure to pathogens between the groups may be due to environmental factors including differences in exposures to other species, habitat quality, nutritional status, and other potential stressors. Differences in health parameters between captive and free-ranging orangutans need to be considered when planning conservation areas, translocation procedures, and rehabilitation protocols. Because survival of the orangutan is linked to animal and ecosystem health, results of this study will assist wildlife conservation programs by providing baseline health information.

Over the past several years, there has been an increase in knowledge pertaining to the diagnosis and management strategies for the herpes family (Types 1-8), the pox viruses, mumps, measles, rubella, and parvovirus B19 as well as the viral etiologies of hepatitis. Various antiviral treatments, such as nucleoside analogs and interferon therapy, have been available to reduce the signs and symptoms of these common viral infections. This article summarizes the preferred treatment strategies to be employed for each of the viruses for reducing severity, duration, recurrences (notably in the herpes family), transmission rates, as well as preventive alternatives. The majority of the therapeutic options attenuate the course of disease. Treatment decisions are driven by knowledge of the natural history and often are tailored to incorporate clinical circumstances for individual patients. Promotion of community awareness and the development of vaccines should be emphasized in the battle against these common viruses, particularly the herpes simplex viruses, the pox viruses, and hepatitis B.

Vaccination has demonstrated the capacity for the drastic decrease of the prevalence and incidence of several diseases of viral etiology and it has allowed their eradication. Among these human immuno preventable diseases are included poliomyelitis, measles, mumps, chicken pox, rubella, hepatitis A and B, influenza A and yellow fever. In residents, travelers to endemic areas and personal at risk, the vaccines to Japanese and equine encephalitis, rabies and adenovirus can be applied. Venezuela has not escaped from the positive impact in the epidemiology of these illnesses as a consequence of the organization and implementation of big national vaccination campaigns; however, and in spite of these efforts, important outbreaks of measles, yellow fever, chicken pox and hepatitis have occurred in the last few years. The tools to eliminate the majority of these viral diseases exist in Venezuela as well as in other countries, and are readily available, effective and relatively not expensive, but require on the whole of an effort of authorities and communities. The implementation of these strategies should have the support of the World Health Organization and the Panamerican Health Organization. This is a priority for the next few years if our aim is the eradication of these illnesses from Venezuela, the continent and the world.

Not many inventions in medical history have influenced our society as much as vaccination. The concept is old and simple. When Edward Jenner published his work on cowpox, "variolation" was quite common. In this procedure, pus of patients with mild smallpox was transferred to healthy individuals. Meanwhile smallpox has been eradicated worldwide. Diseases such as poliomyelitis, diphtheria or tetanus almost disappeared in industrialized countries. The same happened with epiglottitis and meningitis due to Haemophilus influenzae type b (Hib) after vaccination against Hib was introduced in Switzerland in 1990. This success was possible because of routine vaccination. Immunization is a save procedure and adverse events are much lower than complications in the natural course of the prevented diseases. However vaccinations were accused to cause diseases themselves such as asthma, multiple sclerosis, diabetes mellitus, chronic arthritis or autism. Hitherto no large cohort study or case-control-study was able to proof responsibility of vaccines in any of these diseases. Public media are eager to publish early data from surveillance reports or case reports which are descriptive and never a principle of cause and effect. In large controlled trials there was no proof that vaccination causes asthma, hepatitis-B-vaccination causes multiple sclerosis or macrophagic myofasciitis, Hib-vaccination causes diabetes mellitus, rubella-vaccination causes chronic arthritis, measles-mumps-rubella-vaccination causes gait disturbance or thiomersal causes autism. These results are rarely published in newspapers or television. Thus, many caring parents are left with negative ideas about immunization. Looking for the best for their children they withhold vaccination and give way to resurgence of preventable diseases in our communities. This must be prevented. There is more evidence than expected that vaccination is safe and this can and must be told to parents.

Women may be infected during pregnancy with infectious agents that are often passed unnoticed; however, the causative agent may still traverse the placenta and infect the developing embryo and fetus. Several of these agents (i.e. rubella, cytomegalovirus or Toxoplasma Gondii) may cause severe fetal damage, but most other infections in pregnancy seem to be much less dangerous to the fetus. In this review we discuss the effects of several viral infections during pregnancy where the effects on the developing embryo and fetus are infrequent, but they may sometimes cause severe neonatal disease. The following viruses are discussed: coxsackie and echoviruses, measles and mumps, polioviruses, Japanese and Venezuelan equine encephalitis viruses, West Nile virus and hepatitis viruses A, B, C, D and E. Coxsackie B virus may cause an increase in early spontaneous abortions and rarely, fetal myocarditis; echoviruses do not seem to damage the fetus; measles and mumps may cause increased early and late fetal death and neonatal measles or mumps. The viruses affecting the nervous system may increase early and late spontaneous abortions and, rarely, cause severe damage to the fetal brain. Hepatitis B virus has a high rate of vertical transmission causing fetal and neonatal hepatitis. Hepatitis A, C and E are rarely transmitted trans-placentally; if transmitted, they may cause hepatitis. There is no evidence that immunization in pregnancy against these diseases (with attenuated viruses) may adversely affect pregnancy outcome.

Acute pancreatitis develops immediately after the causative impulse, while chronic pancreatitis develops after the long-term action of the noxious agent. A typical representative of acute pancreatitis is biliary pancreatitis, chronic pancreatitis develops in alcoholism and has a long latency. As alcoholic pancreatitis is manifested at first as a rule by a potent attack, it is classified in this stage as acute pancreatitis. The most frequent etiological factors in our civilization are thus cholelithiasis and alcoholism (both account for 20-50% in different studies). The assumed pathogenetic principles in acute biliary pancreatitis are the common canal of both efferent ducts above the obturated papilla, duodenopancreatic reflux and intrapancreatic hypertension. A detailed interpretation is however lacking. The pathogenesis of alcoholic pancreatitis is more complicated. Among others some part is played by changes in the calcium concentration and fusion of cellular membranes. Idiopathic pancreatitis occurs in up to 10%, part of the are due to undiagnosed alcoholism and cholelithiasis. Other etiologies are exceptional. Similarly as in cholelithiasis pancreatitis develops also during other pathological processes in the area of the papilla of Vater such as dysfunction of the sphincter of Oddi, ampulloma and juxtapapillary diverticulum, it is however usually mild. The incidence of postoperative pancreatitis is declining. Its lethality is 30% and the diagnosis is difficult. In the pathogenesis changes of the ion concentration are involved, hypoxia and mechanical disorders of the integrity of the gland. Pancreatitis develops in association with other infections--frequently in mumps, rarely in hepatitis, tuberculosis, typhoid and mycoses. Viral pancreatitis is usually mild. In parasitoses pancreatitis develops due to a block of the papilla Vateri. In hyperparathyroidism chronic pancreatitis is more likely to develop, recent data are lacking. As to dyslipoproteinaemias, pancreatitis develops in the Ist, IVth and Vth type of Frederikson's classification, in rare recessive disorders and other conditions such as hypothyroidism, renal insufficiency, oestrogen substitution and others. In pancreas divisum chronic pancreatitis is more likely to develop. In exotic countries tropical pancreatitis is most frequent. It is however similarly as alcoholic pancreatitis primarily chronic. A very serious course is usual in traumatic pancreatitis. Risk factors of pancreatitis after ERCP are in particular undilated biliary pathways, dysfunction of the sphincter of Oddi and the use of a needle knife (bistoury). Medicamentous prevention is not substantiated. Drug induced pancreatic damage is much rarer than hepatotoxicity. Pancreatitis is caused most frequently by immunosuppressives, methyldopa, corticoids and oestrogens. The question remains to what extent the course of pancreatitis is influenced by its etiology. Biliary, alcoholic, traumatic and postoperative pancreatitis is usually severe, pancreatitis associated with viroses and induced by drugs is usually mild.

The roots and leaves of Isatis indigotica, named 'Ban-Lan-Gen' and 'Da-Qing-Ye', respectively, are widely used for the treatment of influenza, viral pneumonia, mumps, pharyngitis, and hepatitis. The indoxyl derivatives detected in the roots and leaves of I. indigotica have been reported to be biologically active. In the present study, a liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) method was developed to determine indican, isatin, indirubin and indigotin in the roots and leaves of I. indigotica. The method has been validated for linearity, precision and accuracy. Using multiple reaction monitoring (MRM), the limits of detection (LODs) were determined as 0.004 ng for indican, 0.01 ng for isatin, 0.01 ng for indrubin and 0.03 ng for indigotin, while the limits of quantitation (LOQs) were 0.015 ng for indican, 0.04 ng for isatin, 0.04 ng for indirubin and 0.1 ng for indigotin. Compared with previously reported methods, the current method is more rapid, selective and sensitive. This is the first report of the LC/MS/MS determination of indican, isatin, indirubin and indigotin.

Comparative data on fetal and neonatal deaths following maternal mumps, rubella, hepatitis, chicken pox and measles were obtained in a prospective study in New York City from 1957 to 1964, inclusive. The evidence pointed to an increase in early fetal death rate after rubella and mumps and an increase in perinatal mortality after rubella and hepatitis. A significant increase in these rates was not demonstrable for chicken pox and measles in the selected population studied and under the conditions of the present study. The lethal effects of maternal virus diseases were demonstrable in cases of mumps and rubella occurring in the early weeks of gestation and in cases of hepatitis occurring in the late weeks of pregnancy. Fetal death was attributable to severity of maternal disease in hepatitis and to early infection of the fetus in rubella. Other factors related to gonadal infection and to placental and hormonal changes early in pregnancy may be influential in the lethal effect of mumps. Maternal and fetal death occurred in single cases of chicken-pox pneumonia and hepatitis.
