Self-Insertion of Foreign Bodies in Urethra and Bladder: Report of Three Pediatric Cases

Self-inserted urethrovesical foreign bodies are rare in children.We present three cases and discuss the clinical presentation, diagnosis and management of such patients. In case 1, a 16-year-old boy introduced a wire into the urethra and partially into the bladder three days before. In case 2, a 4-year-old boy introduced a hairpin in the urethra in the same day. In case 3, a 11-year-old boy introduced a sewing needle in the urethra a few hours before. Cystourethroscopy and suprapubic cystotomy were used to remove the foreign bodies. The presentation of urethrovesical foreign bodies can vary widely, as can the type of object inserted. Foreign body retrieval is determined by its morphology and the patient’s conditions with the aim to minimise urothelial trauma and preserve erectile function. Definitive treatment is usually the endoscopic removal, however sometimes surgical intervention may be required. It is advocated follow-up with long duration, which is necessary to diagnose the long-term complications including urethral stricture.info:eu-repo/semantics/publishedVersio

Stump Appendicitis in Two Adolescent Boys: Rare Presentations and Alternative Approaches in Pediatrics

Stump appendicitis is a rare complication that results from reinflammation of the residual part of the appendix, after incomplete appendectomy. Factors that may contribute to inadequate identification of appendicular base are subserosal or retrocecal position, extensive inflammation or inadequate surgical exposure. The length of the appendiceal stump after ligation is likely a major predisposing factor. The presentation of stump appendicitis is similar to acute appendicitis, but this diagnosis is often dismissed because of the surgical history. Computed tomography and ultrasonography are the imaging modalities of choice. The usual recommended treatment for stump appendicitis is completion appendectomy. Stump appendicitis must be considered in the differential diagnosis of acute abdomen despite the patient’s appendectomy history. A delayed diagnosis may lead to an increase in morbidity. We present two cases of stump appendicitis in adolescents after laparoscopic appendectomies, one being a case of recurrent stump appendicitis. We report two alternative therapeutic approaches: interval appendectomy and non-operative management. We conclude that these alternative approaches may be suitable for some patients with stump appendicitis. A review of the pertinent literature was done.info:eu-repo/semantics/publishedVersio

A modernização agropecuária nas microrregiões do estado de Minas Gerais

Este estudo objetivou identificar e caracterizar grupos distintos de microrregiões homogêneas quanto ao grau de modernização agropecuária no Estado de Minas Gerais. Para tanto foram empregadas as técnicas de análise fatorial e de análise de agrupamento, a fim de obter os fatores que refletem o padrão tecnológico e cujas relações permitam formar grupos de microrregiões semelhantes. Foram identificados 10 grupos distintos de microrregiões homogêneas, cada um possuindo combinação distinta dos fatores encontrados e que reflete o seu nível tecnológico. Os grupos encontrados constituem informação preliminar para aplicação localizada de políticas de apoio ao setor, bem como para a tomada de decisão por parte dos agentes da iniciativa privada

Perivascular Epithelioid Cell Tumor: A Case Report of a Rare Entity

Perivascular epithelioid cell tumor is a rare mesenchymal tumor with myomelanocytic differentiation. It mainly occurs in middle-aged females and can be found at any location. The differential diagnosis is broad but the immunohistochemical biomarkers establish the diagnosis. A 4-year-old girl was referred to a pediatric gastroenterology clinic due to recurrent umbilical pain and the workup revealed biliary lithiasis. She remained in follow-up, asymptomatic, no physical findings, and stable ultrasound. Six years later, a supra-umbilical mass was detected by ultrasound, and the magnetic resonance imaging revealed a highly vascularized intraperitoneal tumor with well-defined limits. Surgical mass resection was performed, and the histology revealed morphological and immunohistochemical aspects of a perivascular epithelioid cell tumor of the abdominal wall. Given the size of the lesion (> 5 cm) and admitting uncertain malignant potential, she was submitted to margin enlargement. Four years later, she remains asymptomatic without clinical or imagiological evidence of relapse.info:eu-repo/semantics/publishedVersio

Análise da eficiência técnica dos produtores de manga do Vale do São Francisco.

O objetivo geral deste trabalho é analisar o nível de eficiência técnica dos produtores de manga do Distrito de Irrigação Senador Nilo Coelho localizado no Vale do São Francisco, bem como investigar variáveis que afetam a sua eficiência. Para tanto, foi utilizado o método não paramétrico DEA BCC com orientação output. Após a estimação dos escores de eficiência, foi calculado um modelo Tobit considerando esses resultados como variável dependente. Os resultados mais importantes apontaram que características como quantidade de planta por hectare, escolaridade e interação com instituição de pesquisa tendem a elevar os níveis de eficiência, enquanto a existência de dívidas levam a reduzir tais escores

Crescimento de mudas de genótipos de mangabeira (Hancornia speciosa Gomes) em diferentes substratos.

O experimeto foi realizado em Teresina-PI, sob delineamento experimental em blocos casualizados, no arranjo fatorial 6 x 10, seis composições de substratos e dez genótipos de mangabeira, com três repetições

Characterization of volatile substances in apples from rosaceae family by headspace solid‐phase microextraction followed by GC‐qMS

The volatile composition of different apple varieties of Malus domestica Borkh. species from different geographic regions at Madeira Islands, namely Ponta do Pargo (PP), Porto Santo (PS), and Santo da Serra (SS) was established by headspace solid-phase microextraction (HS-SPME) procedure followed by GC-MS (GC-qMS) analysis. Significant parameters affecting sorption process such as fiber coating, extraction temperature,extractiontime,sampleamount,dilutionfactor,ionicstrength,anddesorption time,wereoptimizedanddiscussed.TheSPMEfibercoatedwith50/30 lmdivinylbenzene/carboxen/PDMS (DVB/CAR/PDMS) afforded highest extraction efficiency of volatile compounds, providing the best sensitivity for the target volatiles, particularly whenthesampleswereextractedat508Cfor30 minwithconstantmagneticstirring. A qualitative and semi-quantitative analysis between the investigated apple species has been established. It was possible to identify about 100 of volatile compounds amongpulp(46,45,and39),peel(64,60,and64),andentirefruit(65,43,and50)inPP, PS,andSSapples,respectively.Ethylesters,terpenes,andhigheralcoholswerefound tobethemostrepresentativevolatiles. a-Farnesene,hexan-1-olandhexyl2-methylbutyratewerethecompoundsfoundinthevolatileprofileofstudiedappleswiththelargestGCarea,representing,onaverage,24.71,14.06,and10.80%ofthetotalvolatilefractionfromPP,PS,andSSapples.InPPentireapple,themostabundantcompoundsidentified were a-farnesene (30.49%), the unknown compound m/z (69, 101, 157) (21.82%) andhexylacetate(6.57%).RegardingPSentireapplethemajorcompoundswere a-farnesene(16.87%),estragole(15.43%),hexan-1-ol(10.94),andE-2-hexenal(10.67).a-Farnesene(30.3%),hexan-1-ol(18.90%),2-methylbutanoicacid(4.7%),andpentan-1-ol(4.6%) werealsofoundasSSentireapplevolatilespresentinahigherrelativecontent.Principal component analysis (PCA) of the results clustered the apples into three groups according to geographic origin.
