Aneurisma idiopático de artéria ilíaca comum direita em criança de três anos - relato de caso / Idiopathic right common iliac artery aneurysm in a three-year-old child - case report

Resumo A incidência de aneurismas ilíacos em crianças não é conhecida, havendo apenas alguns relatos de casos na literatura sobre o tema. Neste estudo, é relatado o caso de um paciente masculino, 3 anos, com aneurisma sacular isolado na bifurcação da artéria ilíaca comum direita de origem idiopática, que foi submetido a ressecção, ligadura da artéria ilíaca interna e anastomose vascular término-terminal. Após 1 mês de seguimento, foi diagnosticada oclusão assintomática da anastomose. Devido à presença de circulação colateral, não houve repercussões clínicas da oclusão, e a criança apresentou evolução clínica favorável a médio prazo.

Abstract The incidence of iliac aneurysms in children is unknown and there are only a small number of case reports in the literature on the subject. This article describes the case of a 3-year-old male patient with an isolated saccular aneurysm at the bifurcation of the right common iliac artery, of idiopathic origin, which was repaired by resection, ligature of the internal iliac artery and end-to-end vascular anastomosis. After 1 month of follow-up, he was diagnosed with asymptomatic occlusion of the anastomosis. The occlusion had no clinical repercussions because of collateral circulation and the child has had a favorable clinical course over the medium term.

Circumcision: postoperative complications that required reoperation.

Objective To evaluate post-operative complications of circumcision requiring surgical reintervention. Methods Retrospective analysis of medical records of patients submitted to circumcision from May 1st, 2015 to May 31st, 2016. Results A total of 2,441 circumcisions were performed; in that, 1,940 using Plastibell and 501 by the classic technique. Complications requiring surgical reintervention were found in 3.27% of patients. When separated by surgical technique, 3.4% of circumcisions using Plastibell device required reoperation, as compared to 3% of conventional technique (p=0.79). Preputial stenosis was most frequently found in classic circumcision, with statistical significance (p<0.001). Bleeding was more frequent when using Plastibell device, but the difference was not statistically different (p=0.37). Patients' age was also evaluated to investigate if this variable influenced on the postoperative outcome, but no significant difference was found. Conclusion There was no statistically significant difference when comparing complications between the different techniques performed at this hospital. Preputial stenosis was most frequently found in the classic circumcision, while bleeding was more prevalent when using Plastibell device. Patients' age did not influence in complications.

Activity of antimicrobial combinations against KPC-2-producing Klebsiella pneumoniae in a rat model and time-kill assay.

This study evaluated the efficacy of tigecycline (TIG), polymyxin B (PMB), and meropenem (MER) in 80 rats challenged with Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae infection. A time-kill assay was performed with the same strain. Triple therapy and PMB+TIG were synergistic, promoted 100% survival, and produced negative peritoneal cultures, while MER+TIG showed lower survival and higher culture positivity than other regimens (P = 0.018) and was antagonistic. In vivo and in vitro studies showed that combined regimens, except MER+TIG, were more effective than monotherapies for this KPC-producing strain.

Experimental model for treatment of extended spectrum betalactamase producing-Klebsiella pneumoniae.

BACKGROUND: Animal models are useful to evaluate the efficacy of antimicrobials in experimental sepsis. AIM: To elucidate the steps of producing an experimental model for the treatment of extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae sepsis METHODS: Several ESBL inoculums ranging from 1.5x109 colony-forming units per milliliter (CFU/mL) to 2.0x1010 CFU/mL were administered by peritoneal injection in adults Wistar rats. Outcomes and microbiological data of quantitative peritoneal and blood cultures were observed in untreated animals. Animals which received 2.0x1010 CFU/mL inoculums were treated with single meropenem dose (30mg/kg) after one hour and those which received 1.0x1010 CFU/mL inoculums were treated immediately with three doses of meropenem 50 mg/kg. Outcomes were observed for 24 hours after inoculation. RESULTS: Solutions with 1.5 x109 and 6.0x109 CFU/mL were not lethal within 24 hours. Inoculums of 1.0x1010 CFU/mL were lethal in 80% and solutions with 2.0x1010 CFU/mL were lethal in 100% of animals. ESBL lethal sepsis (1.0x1010CFU/mL) was treated immediately with 50 mg/kg of meropenem every eight hours for 24 hours and presented 40% mortality compared with 80% mortality of the control group (p=0.033). Quantitative cultures of peritoneal fluid presented 104 CFU/mL or less for treated animals compared to more than 105 for untreated animals (p=0.001). CONCLUSION: Inoculums of 1.0x1010CFU/mL achieved the best results to study a model of lethal sepsis and this model of treatment of carbapenem-susceptible Enterobacteriaceae can serve as control to further evaluation of treatment of carbapenemase-producing Enterobacteriaceae models.

RACIONAL: Modelos animais são importantes para avaliar a eficácia de antimicrobianos e a validação do sítio de infecção e a carga bacteriana. OBJETIVO: Definir a concentração do inóculo bacteriano, a dose e o tempo de administração de antimicrobianos a fim de validar um modelo experimental para o tratamento de Klebsiella pneumoniae produtora de betalactamase de amplo espectro em sepse letal. MÉTODO: Inóculos de Klebsiella pneumoniae produtora de betalactamase de espectro estendido de 1,5x109 unidades formadoras de colônias por mililitro (UFC/ml) a 2,0x1010 UFC/ml foram administrados via injeção peritoneal em ratos Wistar adultos. Sobrevida e dados microbiológicos de hemoculturas e culturas quantitativas de fluido peritoneal foram avaliados inicialmente em animais não tratados. Animais inoculados com 2,0x1010 UFC/ml foram tratados dose única de meropenem (30mg/kg) e animais inoculados com 1,0x1010 UFC/ml foram tratados imediatamente com meropenem (50 mg/kg) por 24 horas e os desfechos foram avaliados após 24 horas da inoculação. RESULTADOS: Soluções com 1,5 x109 e 6,0x109 UFC/ml não foram letais. Inóculos de 1,0x1010 UFC/ml e de 2,0x1010UFC/ml foram letais em 80% e 100% dos animais respectivamente. Sepse letal (1.0x1010CFU/mL) com tratamento imediato e por 24 horas apresentou 40% de mortalidade, comparada com 80% nos controles (p=0.033). Culturas quantitativas de fluido peritoneal apresentaram ≤104 UFC/ml enquanto que controles sem tratamento apresentaram >105 UFC/ml (p=0.001). CONCLUSÃO: Modelo experimental com inóculo de 1,0x1010UFC/ml submetido ao tratamento imediato e por 24 horas foi capaz de avaliar resposta microbiológica e de sobrevida podendo ser modelo de embasamento e de controle para tratamento de sepse letal por Klebsiella pneumoniae produtora de carbapenemase. .

[Extract of Passiflora edulis in the healing process of gastric sutures in rats: a morphological and tensiometric study]. / Efeito do extrato da Passiflora edulis na cicatrização de gastrorrafias em ratos: estudo morfológico e tensiométrico.

INTRODUCTION: Many substances of vegetable origin have been used since the beginning of civilization with the purpose of improving the healing process. Among them, dry leaves extract from Passiflora edulis have been shown to have an anti-inflammatory effect in rats. PURPOSE: To analyze the effect of dry leaves extract from Passiflora edulis in the healing of gastric sutures in rats. METHODS: Forty male adult Wistar rats were divided into two groups of 20 rats, called Passiflora group (GP) and Control group (GC) which were divided into two groups of 10 according to moment of death, on day 3 or day 7 after the operation. All animals were submitted to a midline incision and a gastrotomy was performed on the anterior wall of the stomach followed by gastric suture with polypropylene 6.0 using four stitches on a single layer. Rats from GP were given, before closure of the abdominal wall, a solution of Passiflora edulis extract, 250 mg/kg/weight, while rats from the GC were given an isovolumetric isotonic saline solution. Macroscopic evaluation included the adhesion index proposed by Knightly. Bursting pressure was measure by an electronic device. Microscopic analysis was performed including inflammation parameters. RESULTS: All animals presented adequate healing of the abdominal wall with no clinical signs of infections or dehiscence. The adherence index was similar in both groups both on day 3 (p=0.734) and on day 7 (p=1.000). The gastric sutures presented leak with smaller insufflation pressure on the 3rd P.O. day in both groups as compared to the 3rd P.O. day. There was no significant difference of bursting pressure among the subgroups on the 3rd P.O. day (GC3=41.1 +/- 22.1 mmHg versus GP3=59.2 +/- 20.4 mmHg; p=0.074). On the 7th P.O. day, there was an increased mean bursting pressure in both groups, but there was no statistically significant difference between the two groups (p=0.850). Histologic parameters were similar in both groups, on P.O. days 3 and day 7, except for the fibroblastic proliferation, which was greater on the 7th day in GP (p=0.002). CONCLUSION: The intraperitoneal use of Passiflora edulis extract influences favorably the healing of gastric sutures in rats because of the increase in the fibroblastic proliferation on the 7th P.O. day.

Efeito do extrato da Passiflora edulis na cicatrização de gastrorrafias em ratos: estudo morfológico e tensiométrico / Extract of Passiflora edulis in the healing process of gastric sutures en rats: a morphological and tensiometric study

INTRODUÇÃO: Muitas substâncias de origem vegetal são utilizadas desde os primórdios da civilização com finalidade de melhorar a cicatrização. Dentre elas, foi demonstrado em ratos que o extrato de folhas secas de Passiflora edulis tem efeito antiinflamatório. OBJETIVO: Investigar o efeito do extrato de folhas secas de Passiflora edulis na cicatrização das gastrorrafias em ratos. MÉTODOS: Foram utilizados 40 ratos Wistar, machos, adultos, divididos em dois grupos de 20 denominados grupo Controle e grupo Passiflora (GP e GC) subdivididos em grupos de 10 de acordo com o momento do óbito, no 3° e 7° dias de pós-operatório. Todos os animais foram submetidos a laparotomia mediana, na qual foi realizada gastrotomia na parede anterior do corpo seguida da gastrorrafia com fio de polipropileno 6.0, utilizando-se quatro pontos separados, em plano único total. Os ratos do GP receberam na cavidade abdominal, antes do fechamento desta, solução de extrato de Passiflora edulis, na concentração de 250mg/Kg/peso, e os animais do GC igual volume de solução salina isotônica. Foram avaliados aspectos macroscópicos (grau de aderência de Knightly), pressão de ruptura por manômetro eletrônico e parâmetros inflamatórios microscópicos. RESULTADOS: Todos os animais demonstraram boa cicatrização da parede abdominal, sem sinais clínicos de infecção ou deiscência. Não houve diferença estatisticamente significante em relação ao grau de aderências das gastrorrafias nos dois grupos, no 3° dia (p=0,734) e no 7° dia (p=1.000) e nem na comparação do aspecto da mucosa gástrica, no 3° dia e 7° dias (NS). As gastrorrafias apresentaram vazamentos com menor pressão de insuflação nos grupos de animais do 3° dia em ambos os grupos. Não houve diferença significante de pressão de ruptura entre os subgrupos do 3°dia (GC3=41,1±22,1mmHg vs GP3=59,2±20,4 mmHg; p= 0,074). No 7° dia houve maior média de pressão de ruptura, porém sem diferença estatisticamente significante...

Abscesso intrabdominal tardio pós colecistectomia laparoscópica / Late intrabdominal abscess after laparoscopic cholecystectomy

Perforation of the gallbladder during laparoscopic cholecystectomy may be associated with intraperitoneal gallstone spillage. Several complications secondary to lost gallstones in the abdominal cavity have been described. We report a rare complication of abdominal abscess secondary to two gallstones left in the abdominal cavity. A 75-year-old female presented with spontaneous drainage of pus through the umbilicus five years after laparoscopic cholecystectomy. An ultrasonographic evaluation of the abdomen revealed a solid mass of 56x26 mm of diameter, with acoustic shadow, localized distal to the umbilicus. At laparotomy, an abscess with two biliary calculi was drained. The patient had good recovery, with no complication.
