Abstract
RATIONALE Myasthenia gravis (MG) is an autoimmune disease of the neuromuscular junction that can be triggered by anticholinergic agents. PATIENT CONCERNS We present a 4-year-old female patient who was admitted to the outpatient clinic. She complained of drooped eyelids, which first appeared 2 days after taking a 200 mg dose of pyrantel pamoate. Past medical history is negative. DIAGNOSES AND TREATMENT She was hospitalized with a diagnosis of ocular type MG, and pyridostigmine (40 mg/day) treatment was started. OUTCOMES The patient recovered, and subsequently, the treatment dose was tapered. CONCLUSION Pyrantel is an antihelminthic that acts as an agonist of nicotinic acetylcholine receptors (AChRs) of nematodes and exerts its therapeutic effects by depolarizing their muscle membranes. Consequently, there may be an association between pyrantel pamoate and MG.

Abstract
Background Strategies employed by parasites to establish infections are poorly understood. The host-parasite interface is maintained through a molecular dialog that, among other roles, protects parasites from host immune responses. Parasite excretory/secretory products (ESP) play major roles in this process. Understanding the biology of protein secretion by parasites and their associated functional processes will enhance our understanding of the roles of ESP in host-parasite interactions. Methodology/Principal Findings ESP was collected after culturing 10 adult female Ascaris suum. Perienteric fluid (PE) and uterine fluid (UF) were collected directly from adult females by dissection. Using SDS-PAGE coupled with LC-MS/MS, we identified 175, 308 and 274 proteins in ESP, PE and UF, respectively. Although many proteins were shared among the samples, the protein composition of ESP was distinct from PE and UF, whereas PE and UF were highly similar. The distribution of gene ontology (GO) terms for proteins in ESP, PE and UF supports this claim. Comparison of ESP composition in A. suum, Brugia malayi and Heligmosoides polygyrus showed that proteins found in UF were also secreted by males and by larval stages of other species, suggesting that multiple routes of secretion may be used for homologous proteins. ESP composition of nematodes is both phylogeny- and niche-dependent. Conclusions/Significance Analysis of the protein composition of A. suum ESP and UF leads to the conclusion that the excretory-secretory apparatus and uterus are separate routes for protein release. Proteins detected in ESP have distinct patterns of biological functions compared to those in UF. PE is likely to serve as the source of the majority of proteins in UF. This analysis expands our knowledge of the biology of protein secretion from nematodes and will inform new studies on the function of secreted proteins in the orchestration of host-parasite interactions. Ascaris lumbricoides, the most prevalent metazoan parasite of humans, is a public health concern in resource-limited countries. Survival of this parasite in its host is mediated at least in part by parasite materials secreted into the host. Little is known about the composition of these secretions; defining their contents and functions will illuminate host-parasite interactions that lead to parasite establishment. Ascaris suum, a parasite of pigs, was used as a model organism because its genome has been sequenced and it is very closely related to A. lumbricoides. Excretory/secretory products (ESP), uterine fluid (UF) and perienteric fluid (PE) were collected from adult A. suum. Proteins were subjected to LC-MS/MS. ESP proteins (the ‘secretome’) included many also present in UF. Proteins in ESP but not in UF had considerably different characteristics than those in PE or UF, which were similar to each other. We conclude that proteins released from the secretory apparatus have distinct patterns of biological function and that UF proteins are likely derived from PE. Comparing the protein composition of A. suum ESP to ESP from B. malayi and H. polygyrus suggests that the secretome is conserved at the level of both phylogeny and host predilection site.

Abstract
Drug-induced renal injury represents a frequent clinical entity. The most common drugs associated with acute tubular necrosis are aminoglycosides, amphotericin B, radiocontrast agents, and cyclosporine, but no data exist about the potential renal toxicity due to anthelmintics administration. Anthelmintics are commonly considered quite safe agents, and side effects such as gastrointestinal, neurologic, hematologic, or hepatic injury have been only rarely described. We report a 4-year-old boy with persistent massive proteinuria without any other symptoms/signs suggesting nephrotic syndrome (NS). The only relevant anamnestic data was the administration of pyrantel pamoate due to oxyuriasis 7 days before the proteinuria development. The patient was affected by NS diagnosed 6 months before and treated with a 12-week course of corticosteroids. During follow-up, carried out at 3 and 6 months after discharge, he did not show further episodes of proteinuria, and no clinical symptoms/signs suggesting a relapse of NS were ever detected. Considering that the proteinuria observed in our patient spontaneously disappeared after 10 days without any treatment, apart from the interruption of the anthelmintic therapy, we would like to alert pediatricians about the possible occurrence of anthelmintics-related renal complications especially among predisposed patients and to perform a watchful waiting not considering the presence of even massive proteinuria as a certain sign of NS relapse.

Abstract
Many lung infestations from established and newly emerging parasites have been reported as a result of the emergence of HIV/AIDS, the increasing use of immunosuppressive drugs, increasing organ transplantations, the increase in global travel, and climate change. A renewed interest in parasitic lung infections has been observed recently because many protozoal and helminthic parasites cause clinically significant lung diseases. The diseases caused by these parasites may mimic common and complicated lung diseases ranging from asymptomatic disease to acute respiratory distress syndrome requiring critical care management. The availability of new molecular diagnostic methods and antiparasitic drugs enables early diagnosis and prompt treatment to avoid the morbidity and mortality associated with these infestations. Good hygiene practices, improvement in socioeconomic conditions, vector control measures, and consumption of hygienically prepared and properly cooked food are essential to reduce the occurrence of parasitic infestations.

Abstract
OBJETIVO: Apresentar um caso de ascaridíase hepatobiliar complicado por pneumonia lipoídica e discutir as implicações anestésicas envolvidas. DESCRIÇÃO DO CASO: Menina de dois anos de idade com ascaridíase hepatobiliar complicada por pneumonia lipoídica por aspiração e desnutrição grave, advinda de família em condições sociais precárias em zona rural, com quatro irmãos. Foi tratada com sucesso por uma combinação de lavados broncopulmonares sucessivos e cirurgia. COMENTÁRIOS: Ascaridíase biliar corresponde a cerca de 10% dos casos de complicações de ascaridíase. Apenas uma minoria precisa de tratamento cirúrgico. O uso de óleo mineral por via oral é um tratamento tradicional para a suboclusão intestinal pelo Ascaris lumbricoides, mas a broncoaspiração do óleo e a conseqüente pneumonia lipoídica representam um risco alto para o seu uso. Anestesia geral para laparotomia exploradora em pré-escolar desnutrido com pneumonia lipóide e ascaridíase biliar é uma situação pouco contemplada na literatura médica, o que exigiu um planejamento terapêutico específico.

Abstract
PURPOSE OF REVIEW Parasitic pneumonia is being increasingly reported from many parts of the world due to globalization and travel across the continents. This review outlines the recent developments in the diagnosis and management of parasitic pneumonias. RECENT FINDINGS A polymerase chain reaction that can differentiate pathogenic Entamoeba histolytica from nonpathogenic species has been reported. It has been observed that pulmonary infection with Leishmania donovani can occur in immunodeficient and lung transplant patients. Acute respiratory distress syndrome, seen in severe falciparum malaria, has also been observed in vivax malaria. A study has demonstrated the return of chloroquine-sensitive falciparum malaria several years after chloroquine treatment was discontinued. Pulmonary hypertension has been reported in Schistosoma hematobium, S. mansoni and S. japonicum infections. Strongyloides hyperinfection and disseminated disease are frequently reported in immunocompromised individuals. Parenteral ivermectin is found to be useful in the treatment of disseminated strongyloidiasis. A chronic mild interstitial lung disease has been found to persist in tropical pulmonary eosinophilia despite treatment. Studies are in progress to develop vaccines against amoebiasis, malaria and hookworm infections. SUMMARY Parasitic pneumonia can sometimes be life threatening. If proper diagnosis is made early, the pneumonia can be treated successfully with currently available drugs.

Abstract
Schistosomiasis is a disease caused by parasitic trematode worms (schistosomes) that currently affects 200 million people living in tropical and subtropical environments. It is a chronic disease and the latest estimates for sub-Saharan Africa are that it kills > 200000 people every year. Soil-transmitted helminthiasis (STH) is caused by intestinal nematodes. More than 2 billion people are infected worldwide and the disease burden might approach that of malaria. Recognising the enormous public health significance of schistosomiasis and STH, particularly among the poor, and in view of readily available drugs that are safe, efficacious and inexpensive, the World Health Assembly recently set forth a resolution for a combined approach for morbidity control of both diseases. This review briefly summarises the geographical distribution, life cycle and global burden of schistosomiasis and STH. The current arsenal of drugs available for morbidity control, including discovery, chemistry, pharmacological properties and aspects of therapeutic efficacy and adverse events in clinical human use is then discussed. The emphasis is on praziquantel, oxamniquine and artemisinin derivatives (against schistosomes) and albendazole, mebendazole, levamisole, pyrantel pamoate and other compounds (against intestinal nematodes). The experience gained with combination chemotherapy in schistosomiasis and STH is briefly discussed. Finally, current research needs and the critical importance for development of novel anthelmintic drugs, so that chemotherapy can continue to serve as the backbone of integrated and sustainable control of schistosomiasis and STH, is highlighted.

Abstract
OBJETIVO: Discutir as variantes clínicas e táticas para tratamento cirúrgico da ascaridíase biliar complicada. MÉTODO: Trabalho retrospectivo de pacientes operados por complicações de ascaridíase biliar num período de cinco anos. RESULTADOS: São descritos quatro casos de ascaridíase biliar complicada em crianças (três pré escolares e um escolar), expressos através de pseudocisto pancreático, icterícia obstrutiva, colangite e múltiplos abscessos hepáticos, todos tratados cirurgicamente. Descrevemos detalhes técnicos da abordagem operatória para cada um dos casos. CONCLUSÕES: O espectro das afecções biliares secundárias à ascaridíase é variável e é necessário um arsenal de táticas operatórias para a abordagem de cada caso. É desaconselhável o uso de anti-helmínticos antes da resolução clínica da invasão da via biliar. A afecção preferencial de crianças jovens exige o uso de técnicas e materiais adequadamente delicados para a manipulação das vias biliares.

Abstract
Infection with Ascaris lumbricoides constitutes one of the most common helmintic diseases in the world, especially in tropical and subtropical regions. Transmission of this disease involves environmental contamination with eggs, and therefore, is classified as a soil-transmitted disease. The public health importance of ascariasis is made evident by the high number of infected individuals suffering its consequences, which can become severe, depending on the worm burden. Since the introduction of benzimidazoles, chemotherapy has improved significantly, offering fast and direct effects at relatively low cost, as a result of the simple and safe application of these drugs. Unfortunately, the effects are not long-lasting or permanent. The intervention with chemotherapy alone constitutes a fast and efficient way to reduce the worm burden in a population of high prevalence, but does not avoid reinfection. Therefore, the option of integrated control programmes based on chemotherapy in combination with sanitation and health education, together with strong community involvement, must be considered in order to ensure the positive long-term effects of such programmes.

Abstract
Intestinal obstruction in the newborn infant and older child may be due to a variety of conditions, including atresia and stenosis, annular pancreas, malrotation, duplication cyst, meconium ileus, meconium plug syndrome and neonatal small left colon syndrome, Hirschsprung's disease, neoplasia, trauma, and other rarer causes. The mode of presentation can be acute or more chronic with systemic upset due to shock. Neonates, more so than older children, with unrecognized intestinal obstruction deteriorate rapidly, show an increase of associated morbidity and mortality and appropriate surgical treatment becomes more hazardous. Early diagnosis depends largely on the prompt detection of obstructive manifestations by the clinician and the subsequent accurate interpretation of radiographic findings and other investigations, leading to definitive treatment, which should always be preceded by appropriate resuscitation/preparation of the infant/child. Management of intestinal obstruction will almost always be surgical, apart from some notable exceptions and all are discussed in more detail. With the advent of pediatric and neonatal intensive care and multidisciplinary care, the morbidity and mortality of cases of intestinal obstruction reported in current series is generally extremely low and mainly determined by the coexistence of other major congenital anomalies (eg, cardiac), delays in diagnosis and treatment or coexisting medical conditions. Newer treatments and future developments may reduce the residual mortality in such cases as ultrashort-bowel syndrome.

Abstract
AIM: The aim of the study was to investigate the changes of serum malondialdehyde level, i.e; the oxidative stress hypothesis in patients infected with Ascaris lumbricoides.
METHODS: Serum malondialdehyde activity was measured in 43 patients who were positive for intestinal parasite of Ascaris lumbricoides. Scores were obtained for the positives and their age-and sex-matched 60 Ascaris lumbricoides negative healthy controls.
RESULTS: The difference between malondialdehyde levels of patients infected with Ascaris lumbricoides and control group was statistically significant both for females (P < 0.05) and for males (P < 0.05). In the patient and control groups, no correlation was found between age and malondialdehyde levels (P > 0.05) both in females and in males. In addition, no significant correlation could be found between malondialdehyde levels of both females and males for patients and control groups (P > 0.05).
CONCLUSION: Malondialdehyde levels clearly increase in patients infected with Ascaris lumbricoides.
