The objective of this paper was to study snakebites in a pediatric age group treated at a reference hospital and to evaluate factors associated with unfavorable evolution. A cross-sectional study with a clinical-epidemiological description and identification of the factors related to unfavorable evolution in patients aged <19 years old seen from January, 2018 to November, 2019 was performed. Complications related to the SBE, such as compartment syndrome, secondary infection, extensive necrosis, hemorrhage, and kidney damage, were considered unfavorable evolution. From the 325 patients in the sample, 58 were aged <19 years old; 40 (69%), 0-12 years old; and 18 (31%), 13-18 years old. All patients had local manifestations (mild, moderate, and severe), and 36 (62%) had an unfavorable evolution. Fourteen (24.1%) patients had compartment syndrome, with a significant risk association between 0 and 12 years old (p = 0.019). Two factors significantly contributed to unfavorable evolution: the timing from the bite to medical care being ≥6 hours and additional antivenom therapy needed. We conclude that the younger the patient, the smaller body segment affected, leading to disproportionality between the affected area and the amount of inoculated venom, contribute to more frequent local manifestations and complications in children rather than adults. Because of the relationship between body area and vascular volume in children differs from that in adults, the same volume of venom inoculated by snakes will be disproportionate in these two groups. Therefore, in the treatment of pediatric patients, increasing the volume of antivenom therapy is possibly necessary. Furthermore, as in adults, six hours between the bite to medical care increases the risk of complications and mortality. \u0000KEY WORDS: Snakebites envenomation; venom; antivenom; pediatric population.","PeriodicalId":36789,"journal":{"name":"Journal of Tropical Pathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74687473","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 objective of the research was to evaluate the spatial distribution of leprosy cases among the municipalities of the State of Goiás in 2020. This is a descriptive study and the data collection took place from the Notifiable Diseases Information System (SINAN) in November, 2021 and it considered the diagnosis´ year and the patient’s municipality of residence. The following indicators were adopted in the analysis: a) annual prevalence rate per 10,000 inhabitants; b) annual rate of new cases detection in the general population; and c) annual rate of new cases detection in individuals under 15 years of age, these last two per 100,000 inhabitants. The analysis of the spatial occurrence pattern of leprosy in Goiás State municipalities was carried out in the free software Terraview version 4.2.2. A higher prevalence of distribution of the gross rate of the disease was observed in the Central-North and Central-West macro-regions, with a concentration of cases also in the Northeast region of the State. From the 246 Goiás municipalities, 68.7% (n = 169) had cases of leprosy, 18.3% (n = 45) were in a situation of hyperendemia and 23.2% (n = 57) had a very high detection coefficient. Considering the rate of detection in those people under 15 years of age, only 11 municipalities (4.5%) were in a situation of hyperendemia and 1.2% (n = 3) had a very high detection coefficient (5.00 to 9.99/ 10.000 inhabitants). The current investigation indicates the maintenance of leprosy hyperendemic areas in the State of Goiás, when compared to previous studies. This finding highlights the importance of readjustment of leprosy management and assistance in municipalities at greater risk of leprosy hyperendemicity in order to interrupt the M. leprae transmission chain. \u0000KEY WORDS: Leprosy; prevalence; spatial distribution; Goiás State.","PeriodicalId":36789,"journal":{"name":"Journal of Tropical Pathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88041104","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}

From 2018 to 2019, there was a high incidence of severe acute respiratory syndrome (SARS) in the State of Goiás with a relative increase in hMPV incidence. This study aimed to assess the hMPV epidemiology of cases treated at tertiary hospitals of Goiás, as there are not significant published data from hMPV infection in Brazil. We performed a retrospective and descriptive analysis of a case series of patients infected with hMPV diagnosed by PCR (16 individuals), through medical records review from 2017 to 2019. The observed age distribution was bimodal, with the disease affecting individuals at extremes of age (median of 3.5 years old in the first stratum and median of 52 years in the second stratum). The time between the onset of flu-like symptoms and the first medical assessment had an average of 5 days. The most frequent severe symptoms were respiratory distress/dyspnea and oxygen saturation <95% (93.7% as media), even in patients without comorbidities. The most frequent complications were acute renal failure (18.7%) and healthcare-associated infections (43.7%). Death occurred in 37.5% of patients. hMPV may cause upper and lower respiratory tract infections in patients of all age groups, but the symptomatic disease occurs more frequently at extremes of age.

This study aimed to determine the occurrence of parasites in the soil of public squares in the city of Veranópolis in Rio Grande do Sul State. Forty sand samples were collected in four squares throughout the months of December 2021, January, February and March 2022. The samples were processed by the Hoffman, Pons and Janer (HPJ) and Rugai methods. The results showed that 32.5% (13/40) of samples were positive for the presence of parasitic structures. Nematode larvae, including hookworm, were the most prevalent parasitic structures in the samples. In addition, Capillaria sp. eggs, Strongyloides sp. larvae, free-living larvae and Entamoeba coli cysts were also found. Two collections conducted after rainy days had a higher rate of contamination. The presence of parasites was observed in both superficial and deep samples. Therefore, the presence of parasites in the sand of Veranópolis’ public squares demonstrates that there is a risk of parasitic infection for the local population. \u0000KEY WORDS: Animals; parasites; soil; squares; zoonoses.","PeriodicalId":36789,"journal":{"name":"Journal of Tropical Pathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72382787","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}

Herein, we assessed data from the Brazilian Schistosomiasis Control Program (PCE) in the State of Sergipe between the period 2008 and 2017. We evaluated data about schistosomiasis and snails of the genus Biomphalaria. We used the log-linear regression model (joinpoint) to assess temporal trends and the Kernel estimator for spatial statistics analysis. According to the PCE, Sergipe has 51 endemic municipalities for schistosomiasis. Nevertheless, information about the disease and that collected by the PCE has not been recorded regularly in all endemic municipalities. Additionally, only nine municipalities (17.6%) carried out the malacological survey. The average of positive rate from schistosomiasis in Sergipe was 8.4%. However, our data suggest that it may be underestimated. The spatial analysis maps (Kernel maps) showed areas of high transmission of the disease in municipalities close to the São Francisco River and in the metropolitan region of the State. Altogether, our findings suggest that schistosomiasis has been underreported and it is still a serious public health concern in Sergipe.

The consumption of vegetables in Brazil and in the world is common due to their high nutritional value and they are recommended to be included in the population´s diet. Contaminations in vegetables are most often caused by irrigation water which is  contaminated by feces, other forms of contamination are through organic manure containing fecal waste and the contact of vegetables with animals where they are grown. This research evaluated the contamination in vegetables with the purpose of warning the community about hygiene and the correct approach of food handling in order to prevent parasitic infections, contributing to people´s health. Samples were collected from supermarkets and farmers´ markets, where we obtained a total of 30 samples that were analyzed using Hoffman, centrifugation and slide reading´s techniques. In all samples, parasites were found. In six samples non-pathogenic amoebas were found, however this finding means that there was contamination from human or animal feces. And, in the other 24 samples, parasitic structures that cause damage to health were found. This work showed a high level of contamination of the vegetables that are consumed daily by the population and the diseases caused by food which are a concern for the public health.

Identification, susceptibility levels to 13 antibiotics and the presence of extendedspectrum β-lactamases (ESBLs) were determined. Overall, 9,918 microorganisms were isolated as a cause of infection. Of these 3,016 (30.4%) were E. coli, with 1,770 (59%), 992 (33%) and 254 (8%), from the Medicine and the Surgery Departments and the Intensive Care Unit (ICU), respectively. There was a significant increase (p=0.0002) of E. coli throughout considered periods. The isolates presented high levels of resistance (>60%) to cephalosporins, ciprofloxacin and cotrimoxazole, being only susceptible to imipenem (0.3% of resistance) and tigecycline. Overall the analysis of evolution of antimicrobial resistance showed that resistance to cephalosporins and amikacin significantly increased, while, the ones of piperacillintazobactam, cotrimoxazole and gentamicin had significantly decreased. Nevertheless, the ICU isolates showed an inverse scenario for cephalosporins. These findings agree with an increase of ESBLs on the Medicine (56% to 66%; p<0.0001) and on the Surgery (54% to 62%; p=0.0197) departments, with a parallel decrease in the ICU (76% to 68%).
