Data were collected from the Notifiable Diseases Information System (NDIS). 17,056 snakebites were recorded in Amazonas between 2007 and 2017. During the study period, the Rio Negro and Tefé micro-regions had the highest accumulated incidence, while small municipalities such as São Gabriel da Cachoeira, Uarini and Alvarães presenting a high incidence rate during the same period. Snakes in the genera Bothrops and Lachesis caused 69.5% and 20.3% snakebites. Snakebites occurred more frequently in the Amazonian winter, between January and April, and most of the snakebite victims (78.6%) were men. The most affected individuals were between 20 and 39 years of age (59.4%). The time elapsed between snakebites and medical assistance varied from one to six hours (51.4%). 7,705 of the snakebite cases, were classified as moderate, 7,328 as mild, and 1,299 as severe. Of the 104 deaths that occurred in the period, Bothrops genus caused the highest mortality (68.3%). The State of Amazonas recorded both high numbers of snakebites in the period 2007-2017 and the time elapsed between snakebite and medical assistance, which may affect the clinical status of patients.\u0000KEY WORDS: Bothrops; Lachesis; Amazon; snakes; viperidae","PeriodicalId":36789,"journal":{"name":"Journal of Tropical Pathology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87351351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients G1 had a higher prevalence for diabetes and the results indicated 27% prevalence of Candida spp. in vaginal mucosa, in G2 this was 33% in vaginal mucosa. Among the species found in vaginal mucosa of patients, Candida albicans was the most isolated with 88%, followed by C. tropicalis (8%) and C. glabrata (4%). The strains of C. albicans isolated from mucosa presented sensitivity to all antifungal agents tested, unlike the C. tropicalis strain isolated in G2 in vaginal mucosa, which presented a resistance profile to fluconazole. Thus, monitoring and supervision through clinical and laboratory testing of HPV patients is important, reinforcing the need for care, treatment and prevention of HPV-related infections and Candida spp.\u0000KEY WORDS: vaginal mucosa; uterine cervical neoplasms; human Papillomavirus; Candida spp. Antifungal sensitivity.","PeriodicalId":36789,"journal":{"name":"Journal of Tropical Pathology","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82692742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to evaluate the prevalence of parasitic infections, patient lifestyles, health conditions and environmental sources of contamination. One hundred seventy two children and adolescents, 5 to 15 years of age of both sexes were analyzed. Data were obtained through epidemiological questionnaires, parasitological examinations using Paratest®, IgG testing for Entamoeba histolytica, and analysis of sources of contamination in living areas. The study detected a prevalence of 45.9% (79/172) parasitic infections, of which 62.0% (49/79) Entamoeba histolytica/E. dispar complex; 46.8% (37/79) Entamoeba coli; 27.8% (22/79) Giardia intestinalis; 12.7% (10/79) Endolimax nana; 10.1% (8/79) Hymenolepis nana; 8.9% (7/79) Ascaris lumbricoides and 2.5% (2/79) Trichuris trichiura. Out of the 49 samples positive for Entamoeba histolytica complex, there was only one case of antibodies to E. histolytica. The children’s life habits demonstrated inadequate food hygiene practices. These insufficient sanitary parameters revealed a general lack of information in face of an alarming situation regarding sewage and other sources of environmental contamination in 20% of the areas. The high prevalence of protozoan infections despite chemoprophylaxis, with environmental sources of contamination/risk, inadequate health conditions and the general apathy of the population suggest the ineffectiveness of current preventive practices. Thus, it is advisable that control actions include protozoa as therapeutic targets and, above all, health education as a routine practice to prevent the long-term continuance of this vicious cycle.\u0000KEY WORDS: Parasitic infections; chemoprophylaxis; environmental sources.","PeriodicalId":36789,"journal":{"name":"Journal of Tropical Pathology","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85438982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lifetime risk of tuberculosis disease for a person with latent infection is estimated at 5-10% with most cases occurring within five years of initial  infection. The World Health Organization recommends isoniazid preventive therapy (IPT) for latent tuberculosis treatment, amongst other strategies. The aim was to assess tuberculosis  incidence, survival (free of tuberculosis) and associated factors in HIV-positive patients. IPT was offered to participants with a positive (≥5mm) tuberculin skin test. Participants were followed from February 2003-December 2016. Kaplan-Meier was used for survival analysis. Variables with p-value ≤ 0.2 in the univariate analysis entered into the multivariate Cox-Model, keeping those with p-value ≤ 0.05. The 95% confidence interval of incidence of tuberculosis was estimated using Poisson distribution. One hundred nineteen patients completed the IPT and were followed for a median duration of 110.7 months (IQR 93.1-121.0). The probability of developing tuberculosis (10 years post-IPT) was 5.4%. Tuberculosis incidence was 0.58/100 patient/years (CI 95% 0.213-1.264). IPT over 6 months provided long-term protection against tuberculosis.

The purpose of the study was to trace the epidemiological profile of patients who underwent galactomannan test by ELISA with suspected IA and to determine the factors that contribute to the development of the disease. We evaluated 264 patients who underwent galactomannan test with suspected IA from 2013 to 2015.The clinical-epidemiological characteristics were determined using descriptive statistics. The variables were evaluated using the chi-square test (χ2) and the G-test, with p-value considered significant below 0.05. According to the classification for IA by the European Organization for Research and Treatment of Cancer, the disease was considered proven in 7.3%, defined by positive culture for the fungus, 6.4% as probable through detection of galactomannan and the presence of pulmonary infiltrates and 5.1% as possible by radiological alterations suggestive of IA and negative galactomannan test. The mortality rate was 31.6% of all patients and 61.3% for proven / probable / possible IA indicating that the disease was significantly associated with the risk of death. According to these result indications and considering the high mortality rate caused by the development of IA, as well as the fact that early therapy promotes significant improvement in the patients’ prognosis, we conclude that the detection of galactomannan may be considered an effective method to aid the identification of IA.  \u0000KEY WORDS: Invasive pulmonary aspergillosis; neutropenia; enzyme-liked immunosorbent assay; ELISA test searching for Aspergillus; galactomannan.","PeriodicalId":36789,"journal":{"name":"Journal of Tropical Pathology","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73238639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After capture, the specimens of H. aff. malabaricus were analyzed for infection by Contracaecum sp. and Eustrongylides sp. third-stage larvae, and the prevalence, mean abundance, and mean intensity were calculated. A literature search was carried out to clarify the relationship between these indicators and eventual human cases of infection in the Amazon region. Third-stage larvae of nematodes of the Contracaecum and Eustrongylides genera were found in the specimens of H. aff. malabaricus sampled from the Tapajós River. The prevalence of Contracaecum larvae was 100%, while its mean abundance and mean intensity were both 54.8 larvae/fish. The prevalence of Eustrongylides larvae was 62.9%, and its mean abundance and mean intensity were 1.8 and 2.8 larvae/fish, respectively. Despite the high prevalence and intensity values, there are no cases of human infection by these nematode larvae in the Brazilian Amazon reported. The absence of human infections by these nematode larvae in the Brazilian Amazon despite the high prevalence/intensity of Contracaecum and Eustrongylides larvae and the high consumption of fish in the region, is most probably due to the fact that the local populations do not eat raw or undercooked fish. However, it is noteworthy that the absence of zoonotic cases in the region is based only on the examination of the available published papers. A better knowledge of the situation would require surveying hospitals and clinics, and data from the region’s medical treatment facilities. However, the authors consider that cases of human infection, if any, are extremely rare, mainly due to the eating habits of the local population.\u0000KEY WORDS: Amazon basin; freshwater fish; public health; parasitic infection; zoonosis.","PeriodicalId":36789,"journal":{"name":"Journal of Tropical Pathology","volume":"89 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88148296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
