ABSTRACT

Purpose: To observe the effect of puerarin on renal ischemia-reperfusion (I/R) injury in rats, and to explore its mechanism based on NLRP3/Caspase-1/GSDMD pathway. Methods: Twenty-one Sprague-Dawley rats were divided into three groups: sham-operated group (sham), model group (RIRI), and puerarin treatment group (RIRI + Pue). The model of acute renal I/R injury was established by cutting the right kidney and clamping the left renal pedicle for 45 min. Results: Renal function parameters were statistically significant in group comparisons. The renal tissue structure of rats in sham group was basically normal. Pathological changes were observed in the RIRI group. The renal pathological damage score and apoptosis rate in the RIRI group were higher than those in the sham group, and significantly lower in the RIRI + Pue group than in the RIRI group. Indicators of oxidative stress-superoxide dismutase, malondialdehyde, and glutathione peroxidase-were statistically significant in group comparisons. Compared with the sham group, the relative expressions of NLRP3, Caspase-1 and GSDMD proteins in the RIRI group were increased. Compared with the RIRI group, the RIRI + Pue group had significant reductions. Conclusions: Puerarin can inhibit the activation of NLRP3/Caspase-1/GSDMD pathway, inhibit inflammatory response and pyroptosis, and enhance the antioxidant capacity of kidney, thereby protecting renal I/R injury in rats.

ABSTRACT

Cisplatin (CP) is a commonly used, powerful antineoplastic drug, having numerous side effects. Casticin (CAS) is considered as a free radical scavenger and a potent antioxidant. The present research was planned to assess the curative potential of CAS on CP persuaded renal injury in male albino rats. Twenty four male albino rats were distributed into four equal groups. Group-1 was considered as a control group. Animals of Group-2 were injected with 5mg/kg of CP intraperitoneally. Group-3 was co-treated with CAS (50mg/kg) orally and injection of CP (5mg/kg). Group-4 was treated with CAS (50mg/kg) orally throughout the experiment. CP administration substantially reduced the activities of catalase (CAT), superoxide dismutase (SOD), peroxidase (POD), glutathione S-transferase (GST), glutathione reductase (GSR), glutathione (GSH) content while increased thiobarbituric acid reactive substances (TBARS), and hydrogen peroxide (H2O2) levels. Urea, urinary creatinine, urobilinogen, urinary proteins, kidney injury molecule-1 (KIM-1), and neutrophil gelatinase-associated lipocalin (NGAL) levels were substantially increased. In contrast, albumin and creatinine clearance was significantly reduced in CP treated group. The results demonstrated that CP significantly increased the inflammation indicators including nuclear factor kappa-B (NF-κB), tumor necrosis factor-α (TNF-α), Interleukin-1β (IL-1β), Interleukin-6 (IL-6) levels and cyclooxygenase-2 (COX-2) activity and histopathological damages. However, the administration of CAS displayed a palliative effect against CP-generated renal toxicity and recovered all parameters by bringing them to a normal level. These results revealed that the CAS is an effective compound having the curative potential to counter the CP-induced renal damage.


A cisplatina (CP) é uma droga antineoplásica poderosa, comumente usada, com vários efeitos colaterais. Casticin (CAS) é considerado um eliminador de radicais livres e um potente antioxidante. A presente pesquisa foi planejada para avaliar o potencial curativo da CAS em lesão renal induzida por PC em ratos albinos machos. Vinte e quatro ratos albinos machos foram distribuídos em quatro grupos iguais. O Grupo 1 foi considerado grupo controle. Os animais do Grupo 2 foram injetados com 5 mg / kg de PB por via intraperitoneal. O Grupo 3 foi cotratado com CAS (50 mg / kg) por via oral e injeção de CP (5 mg / kg). O Grupo 4 foi tratado com CAS (50 mg / kg) por via oral durante todo o experimento. A administração de CP reduziu substancialmente as atividades de catalase (CAT), superóxido dismutase (SOD), peroxidase (POD), glutationa S-transferase (GST), glutationa redutase (GSR), glutationa (GSH), enquanto aumentou as substâncias reativas ao ácido tiobarbitúrico (TBARS) e níveis de peróxido de hidrogênio (H2O2). Os níveis de ureia, creatinina urinária, urobilinogênio, proteínas urinárias, molécula 1 de lesão renal (KIM-1) e lipocalina associada à gelatinase de neutrófilos (NGAL) aumentaram substancialmente. Em contraste, a albumina e a depuração da creatinina foram significativamente reduzidas no grupo tratado com PC. Os resultados demonstraram que a CP aumentou significativamente os indicadores de inflamação, incluindo fator nuclear kappa-B (NF-κB), fator de necrose tumoral-α (TNF-α), interleucina-1β (IL-1β), interleucina-6 (IL-6) níveis e atividade da ciclooxigenase-2 (COX-2) e danos histopatológicos. No entanto, a administração de CAS apresentou um efeito paliativo contra a toxicidade renal gerada por CP e recuperou todos os parâmetros, trazendo-os a um nível normal. Estes resultados revelaram que o CAS é um composto eficaz com potencial curativo para combater o dano renal induzido por CP.

ABSTRACT

Impalement injuries are a complex and rare type of penetrating abdominal trauma that happens when an object such as a post or a pole penetrates a person injuring several organs, making it a life-threatening situation in which time and correct management play an important part in the survival of the patient. A 37-year-old man suffered abdominal impalement injury with a metal signal post, penetrating the left flank of the abdomen. On examination, there is a hypoventilated left hemithorax with intercostal retractions, increased heart rate, weak distal pulses, delayed capillary refill, and pale skin. A 1-meter-long metal post (approximately 7cm diameter) penetrates the left flank with the entry in the posterior lumbar region. Abdominal viscera, omentum, intestinal content, and ischemic loops of the small intestine are visible. An exploratory laparotomy was performed; left hemicolectomy, end colostomy and Hartmann procedure, resection of the affected jejunum, and end-to-end anastomosis were performed. On the ninth postoperative day, an abdominal tomography was performed due to the presence of fever peaks, which reported thrombosis of the left renal artery and emphysematous pyelonephritis, with the presence of a left pararenal collection. A simple left nephrectomy was performed. Postoperative surveillance was satisfactory during the following 5 days. The patient was discharged. An impaled injury is a complex lesion that needs special attention from the medical field for correct management. Although there is some literature about it, we encourage more research to be done about impalement injuries.


Las lesiones por empalamiento son un tipo de traumatismo abdominal penetrante complejo y raro de que se produce cuando un objeto, como un poste o una vara, penetra a una persona lesionando varios órganos, lo que la convierte en una situación potencialmente mortal en la que el tiempo y el manejo correcto juegan un papel importante en la supervivencia del paciente. Un hombre de 37 años sufrió una herida por empalamiento abdominal con un poste de señales de metal, penetrando el flanco izquierdo del abdomen. A la exploración física, hay un hemitórax izquierdo hipoventilado con retracciones intercostales, aumento de la frecuencia cardíaca, pulsos distales débiles, relleno capilar retrasado y piel pálida. Un poste metálico de 1 metro de largo (aproximadamente 7 cm de diámetro) penetra el flanco izquierdo con entrada en la región lumbar posterior. Son visibles las vísceras abdominales, el epiplón, el contenido intestinal y las asas isquémicas del intestino delgado. Se realizó una laparotomía exploradora; Se realizó hemicolectomía izquierda, colostomía terminal y procedimiento de Hartmann, resección del yeyuno afectado y anastomosis terminoterminal. Al noveno día postoperatorio se realiza tomografía abdominal por presencia de picos febriles, que reporta trombosis de arteria renal izquierda y pielonefritis enfisematosa, con presencia de colección pararrenal izquierda. Se realizó nefrectomía izquierda simple. La vigilancia postoperatoria fue satisfactoria durante los siguientes 5 días. El paciente fue dado de alta. Una lesión por empalamiento es una lesión compleja que necesita una atención especial desde el ámbito médico para su correcto manejo. Aunque existe cierta literatura al respecto, alentamos a que se realicen más investigaciones sobre estas lesiones.

ABSTRACT

Introdução: A insuficiência renal aguda (IRA) ocorre em cerca de 5% das hospitalizações e até 30% das internações em UTI, possuindo taxas de mortalidade entre 15% e 60%. Objetivo: O objetivo do presente trabalho foi analisar diferentes protocolos de indução da IRA em modelo animal, buscando a padronização do modelo para o estudo da relação bidirecional com a periodontite apical (PA). Métodos: Foram utilizados vinte e quatro ratos divididos em três grupos (n=8): G1) administração de gentamicina na dosagem de 80mg/Kg/dia durante cinco dias; G2) administração de gentamicina na dosagem de 100mg/kg/dia durante oito dias; e G3) administração de gentamicina na dosagem de 100mg/kg/dia durante dez dias. A PA foi induzida em todos os grupos por meio da exposição pulpar dos primeiros e segundos molares superiores e inferiores do lado direito. Após trinta dias da exposição pulpar, os animais foram eutanasiados; os rins, coletados para análise histológica em HE; e as maxilas e mandíbulas, removidas para análise radiográfica. Resultados: A presença da PA foi confirmada em todos os espécimes pelo exame radiográfico. O grupo G3 apresentou índice de mortalidade de 75%, enquanto G1 e G2 não apresentaram mortalidade. Histologicamente, o tecido renal do grupo G2 apresentou alterações teciduais, como dilatação e necrose tubular mais severa, quando comparado ao grupo G1 (p<0,05). Conclusão: Diante do alto índice de mortalidade observado em G3 e dos achados histológicos observados em G1 e G2, o protocolo indicado para o estudo da relação bidirecional com a periodontite apical é o de 100mg/kg/dia durante oito dias (AU).


Introduction: Acute Renal Failure (ARF) occurs in about 5% of hospitalizations and up to 30% of ICU admissions, with mortality rates between 15% and 60%. The objective of this study was to analyze different protocols for the induction of IRA in an animal model, seeking the standardization of the model for the study of bidirectional relationship with apical periodontitis (AP). Methods: Twenty-four rats were divided into three groups (n = 8): G1 - Administration of Gentamicin at a dose of 80mg/ kg/day for 5 days; G2 - Administration of Gentamicin at the dose of 100mg/kg/day for 8 days; G3 - Administration of Gentamicin at the dosage of 100mg/kg/day for 10 days. The AP was induced in all groups by means of pulp exposure of the first and second upper and lower molars from the right side. After 30 days, the animals were euthanized, the kidneys collected for histological analysis, and the jaws removed for radiographic analysis. Results: The presence of AP was confirmed in all specimens by radiographic examination. The G3 group had a mortality rate of 75% while G1 and G2 had no mortality. Histologically, the renal tissue of the G2 protocol presented tissue changes such as dilation and more severe tubular necrosis when compared to the G1 protocol (p <0.05). Conclusion: In view of the high mortality rate observed in G3 and the histological findings observed in G1 and G2, the indicated protocol is 100mg/kg/day for 8 days to study the bidirectional relationship with apical periodontitis (AU).

ABSTRACT

We report the case of an 86-year-old adult man who, as a pedestrian, is hit by a motorcycle, suffering polytrauma; in initial care, he refers to thoraco-abdominal pain and subsequently neurological deterioration. Assessed by a neurosurgeon and general surgeon, a right chest tube is placed and a laparoscopy is performed where there is little bleeding from the abdominal cavity. It shows deterioration of its general state and dies in respiratory failure. During the necropsy procedure there is subarachnoid hemorrhage and cerebral herniation, rib fractures and pneumonic consolidation, a massive retroperitoneal hematoma is observed due to rupture of simple renal cyst.

ABSTRACT

O tratamento de desidratação e distúrbios eletrolíticos graves é contraindicado por meio de hipodermóclise, mas o nível de evidência da recomendação se baseia na opinião de especialistas. Descreve-se caso clínico de paciente com idade avançada, com indicação de cuidados paliativos, que evoluiu com desidratação hiperosmolar com hipernatremia grave, injúria renal aguda e hipercalemia. Tratou-se a paciente com solução hipotônica por meio da técnica de hipodermóclise, com resolução completa do quadro. Conclui-se que há necessidade de mais estudos sobre o uso da hipodermóclise para o tratamento de distúrbios hidroeletrolíticos graves.


The treatment of dehydration and severe electrolyte disturbances using hypodermoclysis is usually contraindicated, but the level of evidence for its recommendation is based on expert opinion. This case report describes an older patient receiving palliative care who developed hyperosmolar dehydration with severe hypernatremia, acute kidney injury, and hyperkalemia. She was treated with hypodermoclysis using a hypotonic solution, which led to complete resolution of the condition. In conclusion, further studies on the use of hypodermoclysis for the treatment of severe hydroelectrolytic disorders are needed.

ABSTRACT

ABSTRACT Hypertension and Diabetes mellitus are the two main causes of chronic kidney disease that culminate in the final stage of kidney disease. Since these two risk factors are common and can overlap, new approaches to prevent or treat them are needed. Macitentan (MAC) is a new non-selective antagonist of the endothelin-1 (ET-1) receptor. This study aimed to evaluate the effect of chronic blockade of ET-1 receptor with MAC on the alteration of renal function observed in hypertensive and hyperglycemic animals. Genetically hypertensive rats were divided into control hypertensive (HT-CTL) group, hypertensive and hyperglycemic (HT+DIAB) group, and hypertensive and hyperglycemic group that received 25 mg/kg macitentan (HT-DIAB+MAC25) via gavage for 60 days. Kidney function and parameters associated with oxidative and nitrosative stress were evaluated. Immunohistochemistry for neutrophil gelatinase-associated lipocalin (NGAL), ET-1, and catalase in the renal cortex was performed. The HT+DIAB group showed a decrease in kidney function and an increase in NGAL expression in the renal cortex, as well as an increase in oxidative stress. MAC treatment was associated with attenuated ET-1 and NGAL production and increases in antioxidant defense (catalase expression) and nitric oxide production. In addition, MAC prevented an increase in oxidant injury (as measured by urinary hydroperoxide and lipid peroxidation), thus improving renal function. Our results suggest that the antioxidant effect of the ET-1 receptor antagonist MAC is involved in the improvement of kidney function observed in hypertensive and hyperglycemic rats.


RESUMO Hipertensão e Diabetes Mellitus figuram como as duas principais causas de doença renal crônica que culmina em doença renal terminal. Uma vez que os dois fatores de risco são comuns e podem se sobrepor, novas abordagens preventivas e terapêuticas se fazem necessárias. O macitentan (MAC) é um novo antagonista não-seletivo dos receptores da endotelina-1 (ET-1). O presente estudo teve como objetivo avaliar os efeitos do bloqueio crônico dos receptores da ET-1 com MAC sobre a alteração da função renal em animais hipertensos e hiperglicêmicos. Ratos geneticamente hipertensos foram divididos em grupos com animais hipertensos de controle (HT-CTL), hipertensos e hiperglicêmicos (HT+DIAB) e hipertensos e hiperglicêmicos tratados com 25 mg/kg de macitentan (HT-DIAB+MAC25) via gavagem por 60 dias. Foram avaliados função renal e parâmetros associados ao estresse oxidativo e nitrosativo. Exames de imunoistoquímica foram realizados para lipocalina associada à gelatinase neutrofílica (NGAL), ET-1 e catalase no córtex renal. O grupo HT+DIAB exibiu diminuição da função renal e aumento na expressão de NGAL no córtex renal, bem como estresse oxidativo aumentado. O tratamento com MAC foi associado a atenuação da produção de ET-1 e NGAL e maior ativação das defesas antioxidantes (expressão de catalase) e elevação da produção de óxido nítrico. Além disso, o MAC evitou exacerbação da lesão oxidante (medida por hidroperóxidos urinários e peroxidação lipídica), melhorando assim a função renal. Nossos resultados sugerem que o efeito antioxidante do antagonista dos receptores da ET-1 MAC esteja imbricado no aprimoramento da função renal observada em ratos hipertensos e hiperglicêmicos.

ABSTRACT

ABSTRACT Introduction: The aim of this study was to analyze the presentation and management of major grade renal trauma in children. Method: A retrospective study was performed including data collected from the patients who were admitted in Pediatric surgery with major grade renal injury (grade 3 and more) from January 2015 to August 2018. Demography, clinical parameters, management, duration of hospital stay and final outcome were noted. Results: Out of 13 children (9 males and 4 females), with age range 2-12 years (mean of 8 years), reported self-fall was the commonest mode of injury followed by road traffic accident. The majority (10/13, 75%) had a right renal injury. Eight children had a grade IV injury, one had a grade V injury, and four children had grade III injury. Duration of hospital stay varied from 3 to 28 (mean of 11.7) days. Three children required blood transfusion. One child required image guided aspiration twice and two required pigtail insertion for perinephric collection. All the 13 children improved without readmission or need for any other surgical intervention. Conclusion: Children with major grade renal trauma due to blunt injury can be successfully managed without surgical intervention and minimal intervention may only be needed in select situations.


RESUMO Introdução: O objetivo deste estudo foi analisar a apresentação e tratamento de grande trauma renal em crianças. Método: Foi realizado um estudo retrospectivo incluindo dados coletados dos pacientes que foram internados na cirurgia pediátrica com lesão renal de grau importante (grau 3 ou mais) de janeiro de 2015 a agosto de 2018. Coletamos dados a respeito de demografia, parâmetros clínicos, manejo, tempo de internação e resultado final. Resultados: Das 13 crianças (9 homens e 4 mulheres) com faixa etária de 2-12 anos (média de 8 anos), a queda auto-relatada foi o modo de lesão mais comum seguido de acidente de trânsito. A maioria (10/13, 75%) apresentou lesão renal direita. Oito crianças tiveram uma lesão grau IV, uma apresentou uma lesão grau V e quatro crianças apresentaram lesão grau III. A duração da internação hospitalar variou de 3 a 28 (média de 11,7) dias. Três crianças necessitaram de transfusão de sangue. Uma criança necessitou de aspiração guiada por imagem duas vezes e duas inserções de dreno pigtail exigidas para coleções perinefréticas. Todas as 13 crianças melhoraram sem re-internação ou necessidade de qualquer outra intervenção cirúrgica. Conclusão: Crianças com trauma renal de alto grau devido a lesão contusa podem ser manejadas com sucesso sem intervenção cirúrgica, e intervenção mínima pode ser necessária apenas em situações selecionadas.

ABSTRACT

Disseminated mycosis (DM)­with cardiac involvement and shock­is an unexpected and severe opportunistic infection in patients with yellow fever. DM can mimic bacterial sepsis and should be considered in the differential diagnosis of causes of systemic inflammatory response syndrome in this group of patients, especially in areas where an outbreak of yellow fever is ongoing. We report the case of a 53-year-old male patient who presented to the emergency department with fever, myalgia, headache, and low back pain. The laboratory investigation revealed a positive molecular test for yellow fever, hepatic injury, and renal failure. During hospitalization, the patient developed hepatic encephalopathy, ascending leukocytosis, and ascites, with signs consistent with peritonitis. On the 11th day of hospitalization, the patient developed atrioventricular block, shock and died. At autopsy, angioinvasive mycosis was evidenced mainly in the heart, lungs, kidneys, and adrenals.

ABSTRACT

Le but de ce travail était d'évaluer la prise en charge des traumatismes majeurs du rein dans un hôpital de troisième référence au Mali.Patient et méthodes:Il s'agit d'une étude rétrospective portant sur 7 cas de traumatismes majeurs du rein, colligés au service d'urologie de l'Hôpital Gabriel Touré de Bamako sur une période de 15 mois.Résultats : Les patients se répartissaient en 6 hommes et 1 femme.Nous avons enregistré6 cas de traumatisme fermé et 1 cas de plaie pénétrante du rein. L'âge moyen était de 19 ans. Les étiologies étaient dominées par les accidents de la circulation. Les principaux signes cliniques étaient l'hématurie et les lombalgies. L'état hémodynamique était stable à l'entrée.L'échographie puis la tomodensitométrie rénale ont été réalisées chez tous les patients permettant le diagnostic de traumatisme rénal.Le bilan radiologique permettait de classer les traumatismes selonl'AAST (American Association for the Surgery of Trauma) en : 3 cas de grade IV, et 4 cas de grade III.Notre prise en charge, a consisté en un traitement conservateur chez 5 patients et une chirurgie différée chez 2 patients. L'exploration chirurgicale réalisée a aboutit à une néphrectomie. Par ailleurs, 1 patient a présenté un urinome ayant régressé spontanément au cours de l'hospitalisation. L'évolution clinique était favorable chez tous les patients avec un délai moyen de 3 mois. La tension artérielle était normale chez tous les patients de même que le dosage du taux sérique de la créatinine. Le contrôle radiologique effectué chez les patients ayant présenté un traumatisme au stade IV a montré une reconstruction du rein et une absence d'extravasion de produit de contraste.Conclusion :Les traumatismes du rein sont de plus en plus fréquents. Cette situation est liée à l'augmentation des accidents de la voie publique. Le traitement conservateur même en cas de traumatisme majeur reste la méthode thérapeutique de choix en l'absence d'instabilité hémodynamique. Une surveillance accrue des traumatismes pénétrants par armes à feu semble indispensable pour une exploration chirurgicale précoce en cas de nécessité

ABSTRACT

Abstract Purpose: To determine whether dexmedetomidine (DEX) could attenuate acute kidney injury (AKI) induced by ischemia/reperfusion (I/R) in streptozotocin (STZ)-induced diabetic rats. Methods: Four groups each containing six rats were created (sham control(S), diabetes-sham (DS), diabetes I/R (DI/R), and diabetes-I/R-dexmedetomidine (DI/R-DEX). In diabetes groups, single-dose (65 mg/kg) STZ was administered intraperitoneally (i.p.). In Group DI/R, ischemia reperfusion was produced via 25 min of bilateral renal pedicle clamping followed by 48 h of reperfusion. In Group DI/R-DEX, 50 μg/kg dexmedetomidine was administered intraperitoneally 30 minutes before ischemia. Renal function, histology, apoptosis, the levels of TNF-α, IL-1β, and oxidative stress in diabetic kidney were determined. Moreover, expression of P38 mitogen-activated protein kinase (P38-MAPK), phosphorylated-P38-MAPK(p-P38-MAPK) and thioredoxin-interacting protein (TXNIP) were assessed. Results: The degree of renal I/R injury was significantly increased in DI/R group compared with S group and DS group. The levels of TNF-α, IL-1β, oxidative stress and apoptosis were found significantly higher in DI/R Group when compared with S Group and DS Group. The protein expression of p-P38-MAPK and TXNIP were significantly increased after I/R. All these changes were reversed by DEX treatment. Conclusion: The renoprotective effects of DEX-pretreatment which attenuates I/R-induced AKI were partly through inhibition of P38-MAPK activation and expression of TXINP in diabetic kidney.

ABSTRACT

Abstract Purpose: To evaluate the effect of tadalafil in renal ischemia/reperfusion (I/R) injury in rats Methods: Group I/R saline rats (n=6) were subjected to 45 minutes of left renal ischemia and treated with saline; the I/R tadalafil rats (n=6) received oral 10mg/kg tadalafil microemulsion one hour before ischemia. In both groups, 8 hours after ischemia, laboratory analysis were performed Results: Better tissue perfusion was lower in ischemic left/kidney than in right/kidney in saline group, suggesting reduced kidney clearance. Fluorescence in left/kidneys of tadalafil treated rats was lower than in right/kidneys (difference not significant). The fluorescence signal intensity in kidneys of tadafil treated rats was higher than in saline rats. TNF-α levels were significantly lower in I/R tadalafil group rats compared to I/R saline group (154±10.3 vs 391.3±12.3), as well as IL-1β (163.4±13.2 vs 279±11.5pg/dL), and IL-6 (122.9±8.1 vs 173.7±6.3 respectively; p=0.0001). Urea, creatinine and C-reactive protein were significantly lower in tadafil treated rats then in saline group Conclusion: Tadalafil therapy decreased the expression of circulating pro-inflammatory cytokines in a renal I/R rodent model, while improving kidney function proofs.

ABSTRACT

As is well known, there are different pathophysiological conditions in which baroreflex deficit is enrolled in end-organ damage like hypertension, heart failure and myocardial infarction. The purpose of this study was to investigate the mechanisms enrolled in those relationships using a baroreflex deficit­induced model. Sinoaortic-denervated (SAD) rats were used as a model of arterial baroreflex impairment. Male Wistar rats were divided into: control (n = 9), and SAD (n = 8, 30 days) groups. SAD was performed using the method previously described by Krieger (1964). Cardiac morphology was assessed by echocardiography BP, HR and BP, and pulse interval (PI) variabilities were analyzed using a data acquisition system (Codas, 2kHz). Stroke volume and peripheral and regional resistance were evaluated using colored microspheres. SAD induced LV hypertrophy estimated by LV/BW mass using echocardiography. BP (C: 106±0.6 vs. SAD: 108±2 mmHg) and HR (C: 355±7 vs. SAD: 357±15 bpm) were not modified by SAD, while BP variability (C: 6.2±0.84 vs SAD: 14±0.9 mmHg) and PI variability (C: 24±0.7 vs SAD:17±0.8 ms) were increased and decreased, respectively. Moreover, a reduction was observed in stroke volume (C: 0.31±0.02 vs SAD: 0.25±0.01 mL/ min) and an increase in total peripheral resistance (C: 0.97±0.07 vs. SAD: 1.23±0.07 mL/min/mmHg) in SAD animals. Those alterations resulted in increased cardiac vascular resistance (C: 35±1.6 vs. SAD:66±2.3 mmHg/mL/min/g) and renal vascular resistance (C: 31±1.2 vs. SAD: 75±2.2 mmHg/mL/min/g) in the SAD group. SAD induced an augment in cardiac and renal damage as cardiac morphology by histological techniques showed increased arterial wall and interstitial fibroses, and renal morphology showed interstitial fibroses and a decreased Bowmann space. Conclusion: Total baroreflex dysfunction impaired BP and HR variabilities associated with decreased stroke volume and increased peripheral and regional resistance. These adjustments may play an important role in target organ damage in different pathological conditions; even BP values were maintained at the control levels


Existem diferentes condições fisiopatológicas em que o déficit de barorreflexo está associado ao dano do órgão final, como hipertensão, insuficiência cardíaca e infarto do miocárdio. O objetivo deste estudo foi investigar os mecanismos inscritos nestes relacionamentos usando um modelo induzido por déficit de barorreflexo. Foram utilizados ratos com desnervação sino-aórtica (SAD) como modelo de comprometimento barorreflexo arterial. Os ratos Wistar machos foram divididos em grupos controle (n = 9) e SAD (n = 8, 30 dias). O SAD foi realizado utilizando o método anteriormente descrito por Krieger (1964). A morfologia cardíaca foi avaliada pela ecocardiografia PA, e as variabilidades de FC e PA, e do intervalo de pulso (IP) foram analisadas usando um sistema de aquisição de dados (Codas, 2kHz). O volume sistólico e a resistência periférica e regional foram avaliados utilizando microesferas coloridas. SAD induziu hipertrofia do VE estimada pela massa de VE/PC usando ecocardiografia. PA (C: 106±0,6 vs. SAD: 108±2 mmHg) e FC (C: 355±7 vs. SAD: 357±15 bpm) não foram modificados pelo SAD, enquanto a variabilidade da PA (C: 6,2±0,84 vs. SAD: 14±0,9 mmHg) e a variabilidade de PI (C: 24±0,7 vs. SAD: 17±0,8 ms) aumentaram e diminuíram, respectivamente. Além disso, observou-se uma redução no volume sistólico (C: 0,31± 0,02 vs SAD: 0,25 ± 0,01 mL/min) e um aumento na resistência periférica total (C: 0,97±0,07 vs. SAD: 1,23±0,07 mL/min/mmHg) em animais SAD. Essas alterações resultaram em aumento da resistência vascular cardíaca (C: 35±1,6 vs. SAD: 66 ± 2,3 mmHg/mL/min/g) e resistência vascular renal (C: 31±1,2 vs. SAD: 75±2,2 mmHg/mL/min/g) no grupo SAD. SAD induziu um aumento no dano cardíaco e renal como a morfologia cardíaca por técnicas histológicas mostrou aumento da parede arterial e fibrose intersticial, e a morfologia renal mostrou fibrose intersticial e uma diminuição do espaço de Bowmann. A disfunção barorreflexa total prejudicou as variabilidades de PA e FC associadas à diminuição do volume sistólico e ao aumento da resistência periférica e regional. Esses ajustes podem desempenhar um papel importante no dano de órgãos alvo em diferentes condições patológicas; até mesmo os valores da PA foram mantidos nos níveis de controle

ABSTRACT

Antecedentes: existe una tendencia creciente hacia el tratamiento no operatorio (TNO) en el trauma-tismo cerrado de abdomen (TCA), en pacientes estables hemodinámicamente, sin abdomen agudo peritoneal. No hay consenso sobre: momento de inicio de la dieta, deambulación, proflaxis anttrom-bótica, seguimiento y control, y reinicio de la actividad fisica. Objetivo: describir los resultados del manejo de pacientes con TCA, admitidos en nuestro Servicio de Cirugía. Material y métodos: incluimos pacientes mayores de 15 años internados desde enero de 2011 hasta septembre de 2014, con TCA sometidos a TNO. Se recabaron las variables analizadas de una base de datos electrónica de fichaje prospectivo. Resultados: del total de pacientes 31 TCA, 15 se intervinieron quirúrgicamente al ingreso y 16 pacientes se someteron a TNO. El 73,3% presentó lesiones asociadas extraabdominales. A todos se les realizó ecografa abdominal, donde se encontró líquido libre en el 80% y se identificó lesión de órgano sólido en el 60%. En 11 pacientes se realizó TC confrmando lesión objetivada en la ecografa e iden-tificando 3 no evidenciadas previamente. Se diagnosticaron 5 traumatismos hepáticos, 2 asociados a traumatismo renal; 6 traumatismos esplénicos, 4 renales y un paciente con hemoperitoneo. En 7 pacientes se utlizó tromboproflaxis. El TNO fue exitoso en todos los casos. Tres pacientes presentaron complicaciones. No se registró mortalidad. Conclusiones: los pacientes sometidos a TNO en nuestro hospital fueron tratados exitosamente en todos los casos. No se registró mortalidad en la serie analizada.


Background: there is a growing trend towards non-operative management (NOM) in the blunt abdominal trauma (BAT) in hemodynamically stable patentis without peritoneal acute abdomen. However, there is stll no consensus on: tme of onset of diet, ambulaton, antthrombotic prophylaxis, follow-up, and resumpton of physical activity. Objective: to describe the management of patentis with BAT, admited to the Department of Surgery of our insttuton. Material and methods: we included patentis age 15 and older admited from January 2011 to Sept-ember 2014, with BAT who underwent NOM. The variables analyzed were collected from an electronic database of prospective signing. Resultis: 31 TCA were identifed, 15 were operated on at admission and 16 patentis underwent NOM. 75% were men; mean age of 29 (range 18-58). In 100% abdominal ultrasound was performed, finding free fuid in 80% and identifying organ damage in 60% of the total. In 11 patentis CT scan was perfor-med confrming identifed organ injury on ultrasound and diagnosing three not evidenced previously. We included 5 patentis with liver trauma, 2 associated renal trauma; 6 splenic trauma; 4 kidney trauma and 1 patent with hemoperitoneum. Thromboprophylaxis was used in 7 patentis. NOM was successful in all cases. Three patentis presented complicatons, not associated with trauma. No mortality was recorded. Conclusions: patentis undergoing NOT in our hospital were successfully treated in all cases. There were no complicatons associated with management of the NOT. No mortality was recorded.

ABSTRACT

ABSTRACT Objective: to study the profile of victims of kidney trauma who underwent surgical and medical treatment in a hospital in Curitiba. Methods: we conducted a retrospective, analytical, quantitative, cross-sectional study of patients with renal trauma admitted to the Evangelical Hospital of Curitiba between February 2011 and January 2014. Results: participated in the study 38 patients, four women and 34, men with a mean age of 28.4 years. Most injuries (60.5%) was due to closed mechanisms, especially motorcycle accidents. Injuries were treated conservatively in most cases. Patients who required surgical treatment had severe kidney damage or some other associated lesion, usually intra-abdominal. Hospital stay was lower in the conservative treatment group (10.8 days) compared with the surgical treatment one (18.8 days); mortality was also lower in the conservative treatment group (8.3%) compared with the surgical (14.3%). There were no deaths associated to kidney damage itself. Conclusion: patients with renal trauma in this study were young men, victims of motorcycle accidents, taking place during the night and early morning. Most injuries were treated conservatively.


RESUMO Objetivo: estudar o perfil das vítimas de traumas renais submetidos a tratamento cirúrgico e clínico em um hospital de Curitiba. Métodos: estudo transversal quantitativo analítico retrospectivo de pacientes com trauma renal admitidos no Hospital Universitário Evangélico de Curitiba entre fevereiro de 2011 e janeiro de 2014. Resultados: fizeram parte do estudo 38 pacientes, sendo quatro mulheres e 34 homens, com média de idade de 28,4 anos. A maior parte dos traumas (60,5%) foi decorrente de mecanismo fechado, em especial acidentes automobilísticos envolvendo motos, tratados de maneira conservadora na maior parte dos casos. Os pacientes que necessitaram de tratamento cirúrgico possuíam lesões renais graves ou alguma outra lesão associada, geralmente intra-abdominal. O tempo de internamento foi menor no grupo de tratamento conservador (10,8 dias) em relação ao grupo de tratamento cirúrgico (18,8 dias), assim como a mortalidade também foi menor no grupo de tratamento conservador (8,3%) comparada ao cirúrgico (14,3%). Nenhuma morte foi relacionada à lesão renal em si. Conclusão: os pacientes com traumatismo renal neste estudo foram homens jovens, vítimas de acidentes automobilísticos com motos, ocorrendo durante a noite e madrugada. A maioria das lesões foi tratada de modo conservador.

ABSTRACT

Systemic hypertension is known to be a common consequence of chronic renal disease, which is frequently diagnosed in dogs with visceral leishmaniasis. Although many veterinary investigations have looked at the renal injury caused by Leishmania spp., the role played by this complication in the development of arterial hypertension documented in some animals with visceral leishmaniasis is not completely understood. In this study, 18 adult dogs with naturally-occurring visceral leishmaniasis and varying clinical signs underwent an indirect blood pressure measurement. Also, sera and spot urine were used for laboratory tests. The median systolic blood pressure was 135.2mmHg (95% confidence interval: 128.5-147.7), median mean arterial pressure was 105.8mmHg (98.3-110.4), and median diastolic arterial pressure was 88.5mmHg (77.8-92.5). No differences existed between asymptomatic and symptomatic animals regarding arterial pressure, and no correlations were documented between blood pressure and serum creatinine, blood urea, urine protein-to-creatinine ratio, urine specific gravity, and the fractional excretion of sodium and potassium. Although an association between hypertension and the identification of inflammation on histopathology could not be demonstrated in hypertensive animals, the assessment of kidney samples from 12 dogs indicated mild inflammation with a lymphoplasmacytic infiltrate (6/12), moderate inflammation with multifocal lymphoplasmacytic and histiocytic infiltrates (3/12), and multifocal degeneration and protein casts (2/12). Anti-Leishmania spp. immunohistochemistry assays stained the renal epithelium in 2/12 of the animals. Even though mild systemic hypertension was documented in a small subset of animals, no relationship between the severity of clinical signs and hypertension could be anticipated.(AU)


A hipertensão sistêmica é reconhecida como uma consequência comum da doença renal crônica, cujo diagnóstico é frequente em cães com leishmaniose visceral. Embora muitas pesquisas veterinárias tenham investigado a lesão renal causada pela Leishmania spp., o papel dessa complicação no desenvolvimento da hipertensão arterial documentada em alguns animais com leishmaniose visceral ainda não é completamente compreendido. Neste estudo, 18 cães adultos com diagnóstico de leishmaniose visceral e sinais clínicos variáveis foram submetidos à avaliação indireta da pressão arterial. Além disso, foram coletados soro e urina para análises laboratoriais. As medianas das pressões arteriais sistólica, média e diastólica foram 135,2mmHg (intervalo de confiança de 95%: 128,5-147,7), 105,8mmHg (98,3-110,4) e 88,5mmHg (77,8-92,5), respectivamente. Não foram constatadas diferenças entre os cães assintomáticos e sintomáticos em relação à pressão arterial, assim como não houve correlação entre a pressão arterial e a creatinina e uréia séricas, relação proteína-creatinina urinária, densidade urinária e excreção fracionada de sódio e potássio. Embora não tenha sido evidenciada associação entre hipertensão arterial e inflamação do tecido renal à histopatologia, a avaliação das amostras oriundas de 12 cães indicou inflamação leve, com infiltrado linfoplasmocitário (6/12), inflamação moderada com infiltrados linfoplasmocitário e histiocítico multifocais (3/12), além de degeneração multifocal e cilindros protéicos (2/12). Ensaios imunoistoquímicos anti-Leishmania spp. marcaram o epitélio renal em 2/12 animais. Apesar de hipertensão leve ter sido documentada em uma pequena parcela dos cães estudados, não se evidenciou relação entre a severidade dos sinais clínicos e o desenvolvimento de hipertensão arterial.(AU)
