Antioxidant mediated defensive potency of Caesalpinia bonducella nut on Acetaminophen-inebriated spleen and cardiotoxicity: Implications on oxidative stress and tissue morphology in an In vivo model

Overdosing on medications can be unintentional or deliberate. Acetaminophen (APAP) is a widely used over-the-counter analgesic and antipyretic drug. APAP overdose can induce spleen and cardiotoxicity apart from hepatotoxicity. Bonduc nut is well-known for its medicinal and therapeutic properties. More scientific data is necessary to be therapeutically relevant. This study examined the effects of Bonduc nut extract (BNE) on APAP-induced spleen and cardiotoxicity in Wistar albino rats. The rats were divided into five groups of six rats each. In vitro assays were carried out to analyze antioxidant activity and free radical scavenging activity in aqueous, ethanol, and methanol solvents in Bonduc nut powder. Total phenolic content, DPPH, catalase, and peroxidase activity were used to test antioxidant activity. The rats were euthanized after the study period to examine antioxidant parameters such as superoxide dismutase, catalase, reduced glutathione, and glutathione peroxidase, as well as lipid peroxidation and histopathology of the spleen and heart tissues. Results suggest that compared to other solvents aqueous has better Invitro antioxidant ability and the same extract significantly increased the antioxidant and reduced lipid peroxidation followed by restoring the tissue morphology in APAP-induced spleen and cardiotoxicity. The outcome of the study revealed that aqueous BNE has a significant protective efficacy against APAP-induced spleen and cardiotoxicity in Wistar albino rats.

Correlation of rib fracture patterns with abdominal solid organ injury: A retrospective observational cohort study / 中华创伤杂志(英文版)

PURPOSE@#Rib fractures are one of the most common causes of morbidity and mortality and are associated with abdominal solid organ injury (ASOI). The purpose of this study was to investigate the correlation of ASOI with the number, location, and involved segments of rib fracture(s) in blunt chest trauma.@*METHODS@#This retrospective cohort study was conducted on patients with blunt chest trauma over the age of 15 years, who were hospitalized with the diagnosis of rib fractures from July 2015 to September 2020. After ethic committee approval, a retrospective chart review was designed and patients with a diagnosis of rib fractures were selected. Patients who had chest and abdominopelvic CT scan were included in the study and additional data including age, gender, injury severity score, trauma mechanism, number and sides of the fractured ribs (left/right/bilateral), rib fracture segments (upper, middle, lower zone) and results of chest and abdominal spiral CT scan were recorded. The correlation between ASOI and the sides, segments and number of rib fracture(s) was assessed by Pearson's correlation coefficient.@*RESULTS@#Altogether 1056 patients with rib fracture(s) were included. The mean age was (42.76 ± 13.35) years and 85.4% were male. The most common mechanism of trauma was car accident (34.6%). Most fractures occurred in the middle rib zone (60.44%) and the most commonly involved ribs were the 6th and 7th ones (15.7% and 16.4%, respectively). Concurrent abdominal injuries were observed in 103 patients (34.91%) and were significantly associated with middle zone rib fractures.@*CONCLUSION@#There is a significant relationship between middle zone rib fractures and ASOI. Intra-abdominal injuries are not restricted to fractures of the lower ribs and thus should always be kept in mind during management of blunt trauma patients with rib fractures.

Lesión esplénica accidental en cirugía ginecológica laparoscópica asociada con la técnica de entrada. Reporte de un caso y revisión bibliográfica / Incidental splenic injury during laparoscopic gynecological surgery associated with the entry technique. A case report and literature review

Resumen: ANTECEDENTES: Las lesiones accidentales del bazo durante la cirugía laparoscópica ginecológica son complicaciones raras, con gran repercusión en la morbilidad y mortalidad perioperatoria. La cirugía laparoscópica mediante compresión asistida y administración de hemostáticos es una opción viable en pacientes con lesiones esplénicas derivadas del acceso de los trocares. CASO CLÍNICO: Paciente de 48 años, con síndrome anémico secundario a trastornos (hipermenorrea y metrorragias) menstruales de seis meses de evolución, atendida en el departamento de Ginecología del Hospital General Dr. Manuel Gea González donde se clasificó con P0A0L1M0-C0O1E1I0N0 (FIGO 2011). Se decidió la histerectomía laparoscópica con salpingooforectomía bilateral. Durante el procedimiento quirúrgico tuvo sangrado activo, dependiente de la pared esplénica. Se ejerció compresión del sitio sangrante y se aplicó Surgicel® (producto hemostático absorbible-Ethicon), con adecuada hemostasia. La paciente evolucionó satisfactoriamente y fue dada de alta sin contratiempos. CONCLUSIÓN: Existen pocos reportes de lesiones esplénicas accidentales en cirugía ginecológica laparoscópica. La parte más peligrosa es la introducción de la aguja de Veress y del trócar, que pueden provocar lesiones viscerales o a vasos sanguíneos. Las pacientes con lesiones esplénicas accidentales deben ser tratadas por un equipo multidisciplinario.

Abstract: BACKGROUND: Incidental spleen injuries during gynecological laparoscopic surgery are rare complications that have a major impact on perioperative morbidity and mortality. Laparoscopic management through assisted compression and haemostatic products has been a recommended option in patients who have splenic lesions secondary to the path of laparoscopic trocars. CLINICAL CASE: 48-year-old patient with anemic syndrome secondary to 6-month-old menstrual disorders. It is protocolized in the Department of Gynecology of the Hospital Dr. Manuel Gea González where it is classified P0A0L1M0 - C0O1E1I0N0 (FIGO 2011). It is proposed for laparoscopic hysterectomy with bilateral salpingophrectomia. In the surgical act there is active bleeding dependent on splenic wall. It is compressed from the bleeding site and Surgicel® (absorbable hemostatic product - Ethicon) is applied, presenting hemostasis. The patient evolved successfully and left without incident. CONCLUSION: There are few documented reports of incidental splenic injuries in laparoscopic gynecological surgery. The most dangerous part of laparoscopy is the introduction of the Veress needle and the trocar, where visceral lesions or blood vessels may occur. Timely diagnosis of these complications is important for proper treatment. Incidental splenic injuries should be treated by a multidisciplinary team.

Focused Abdominal Sonography In Trauma (FAST) In Patients With Blunt Trauma Abdomen In Rural Area- A Prospective Study

Background: Unrecognized blunt abdominal injuries are often causing of the preventable death. Clinical examination is frequently inaccurate and therefore, the reliable, accurate and repeatable bed-side diagnostic test should be chosen such as Sonography. This study was under-taken to assess Focused Assessment Sonography in Trauma (FAST) examination for in rural area in the patients with Blunt Abdominal Trauma.Material and Methods:This was the prospective study including all the trauma team cases in a 24 months period between March 2016 to February 2018 in emergency department of a Uttarpradesh University of Medical Sciences& hospital,Saifai. The results of the FASTscans were analyzed and when the FASTwas positive or followed by the period of the clinical observation when FASTwas negative. Descriptive statistics & sensitivity, specicity, & predictive values were calculated.Results: Total of 100 patients were included in our study and the majority of them were males and the commonest cause of injury was a Road Trafc Accident. The sensitivity & specicity of FASTwere 92.68% and 98.31%, respectively, with an accuracy of 96.0%.Conclusion:Our study found that FASTis the highly sensitive, specic, accurate initial bedside and reliable investigation in the patients with blunt abdominal trauma, which may be done rapidly even in the haemodynamically unstable patients, making it a useful tool.

Mesenteric lymph reperfusion exacerbates spleen injury caused by superior mesenteric artery occlusion shock

The intestinal lymph pathway plays an important role in the pathogenesis of organ injury following superior mesenteric artery occlusion (SMAO) shock. We hypothesized that mesenteric lymph reperfusion (MLR) is a major cause of spleen injury after SMAO shock. To test this hypothesis, SMAO shock was induced in Wistar rats by clamping the superior mesenteric artery (SMA) for 1 h, followed by reperfusion for 2 h. Similarly, MLR was performed by clamping the mesenteric lymph duct (MLD) for 1 h, followed by reperfusion for 2 h. In the MLR+SMAO group rats, both the SMA and MLD were clamped and then released for reperfusion for 2 h. SMAO shock alone elicited: 1) splenic structure injury, 2) increased levels of malondialdehyde, nitric oxide (NO), intercellular adhesion molecule-1, endotoxin, lipopolysaccharide receptor (CD14), lipopolysaccharide-binding protein, and tumor necrosis factor-α, 3) enhanced activities of NO synthase and myeloperoxidase, and 4) decreased activities of superoxide dismutase and ATPase. MLR following SMAO shock further aggravated these deleterious effects. We conclude that MLR exacerbates spleen injury caused by SMAO shock, which itself is associated with oxidative stress, excessive release of NO, recruitment of polymorphonuclear neutrophils, endotoxin translocation, and enhanced inflammatory responses.

Extension of Nonoperative Management on Spleen Injury with Judicious Selection and Embolization; 10 Years of Experience

PURPOSE: We describe clinical outcomes of NOM on spleen injuries with judicious selection and embolization during the past 10 years. METHODS: From March 2000 to November 2009, 151 patients with splenic injury were included. Eighteen patients were excluded because of incomplete data. Patients' medical records were reviewed to examine admission demographics, laboratory results, radiologic findings as well as transfusion requirement, hospital stay, and ultimate outcomes. RESULTS: Twenty patients were chosen for non-operative management (NOM) after splenic embolization and 1/20 (5%) patient failed. There were 32 patients more than 55 years old (range, 55~87 years). Of these patients, 26 (81%) patients were chosen for NOM and 3 (11.5%) patients failed. According to OIS, 51 patients were grade 3; 26 patients, grade 4; and 6 patients, grade 5. Among grade 3, 49 (96%) were chosen for NOM with or without embolization and 1 (2%) patient failed; grade 4, 19 (73%) with NOM, 2 (7.6%) patients failed. Of all 133 patients with NOM or failed NOM (FNOM), there was 0 mortality in grade 3; 2, in grade 4; 2, in grade 5, excluding other causes of death. The mean ISS was significantly higher in the failed NOM group compared with successful NOM group (P=0.01). The group of failed NOM had a significantly higher mean OIS (P=0.00). CONCLUSION: Aggressive but highly selective NOM on the base of clinicoradiologic parameters with the aid of angioembolization would result in a low failure rate and complication in the management of high grades (grade 3 or 4).
