Symptoms, course, and complications of abdominal attacks in hereditary angioedema due to C1 inhibitor deficiency.
2006
Recurrent abdominal attacks belong to the cardinal and most distressing symptoms of hereditary angioedema (HAE) due to C1 inhibitor deficiency. They are characterized by crampy pain, but may include vomiting, diarrhea, and other features. Detailed clinical data about the symptoms and course of abdominal attacks have not been reported.We retrospectively observed a total of 33,671 abdominal attacks in 153 patients with HAE including a prospectively examined subgroup of 23 patients. Symptoms, course, frequency of attacks, and complications were analyzed.The relation of mild, moderate, and severe attacks was 1:1.4:5.6 in the prospective part of the study. Extra-abdominal symptoms preceded the a…
Ultrasound as first line step in anaemia diagnostics
2019
This review covers the role of ultrasonography as an essential non-invasive diagnostic approach when facing patients with anemia, a common clinical problem. Abdomen ultrasound is well recognized as a first-line examination in the setting of blood loss, both acute and chronic. Less is clear about the additional opportunities, given by ultrasound in anemia, due to the many other possible causes.
 Here we provide information on the utility of ultrasound in different contexts and a practical guide for clinicians facing anemic patients
PLASMA PROTEIN LOSS DURING SURGERY: BENEFICIAL EFFECTS OF ALBUMIN SUBSTITUTION
2001
Plasma protein loss during abdominal surgery is a known phenomenon, but its possible pathophysiological relevance has remained unknown. The present study evaluates the effects of albumin substitution on systemic and local hemodynamics and cellular interactions in the mesenteric microcirculation. Rats underwent median laparotomy and exteriorization of an ileal loop for intravital microscopy of the mesenteric microcirculation. Plasma protein concentrations, systemic and local hemodynamics were recorded during the follow up period, with or without albumin substitution. Depending on the time course of plasma protein loss in control experiments, 80% of the calculated protein loss was infused dur…
Evaluating the efficacy of current treatments for reducing postoperative ileus: a randomized clinical trial in a single center.
2014
AIM: Postoperative ileus has been considered an inevitable consequence of abdominal surgery. The aim of the study was to investigate the efficacy of same treatments in resolving postoperative ileus in various surgical approaches. METHODS: A total of 360 patients underwent abdominal surgery, and was divided into four groups: videolaparoscopic cholecystectomy, laparotomic colo-rectal surgery, laparotomic Hartmann procedure, laparotomic gastric surgery. In each group, patients received different postoperative treatments: chewing gum, olive oil, both, and water. Each group was compared with a control group. RESULTS: In patients who underwent videolaparoscopic cholecystectomy, median postoperati…
Abdominal scintigraphy for diagnosis of intestinal bleeding
1978
Abdominal scintigraphy with99mTc-pertechnetate, using a gamma-camera linked to a data processor, was done in 8 patients with acute massive intestinal hemorrhage and in 34 patients with chronic recurrent intestinal hemorrhage. Endoscopy and x-ray studies had failed in all patients to reveal a bleeding source. All but 3 patients underwent exploratory laparotomy, confirming the abnormal findings of scintigraphy. In all acutely bleeding patients, scintigraphy was positive. The bleeding was proven by laparotomy to be due to Meckel's diverticulum with gastric mucosa in 5, jejunal neurinoma in 1, and sigmoid colon carcinoma in 1 patient. Scintigraphy was positive in only 3 chronically bleeding pat…
Nitric Oxide Opposes Myogenic Pressure Responses Predominantly in Large Arterioles In Vivo
1998
Abstract —A myogenic vasoconstriction may amplify the effects of circulating vasoconstrictors. In cremaster arterioles, the contribution of a myogenic component to the constriction on intravenous infusion of norepinephrine (NE) or angiotensin II (Ang II) was studied. Second, the role of endothelium-derived nitric oxide (NO) in the control of these myogenic constrictions and its site of action in the resistance vascular bed was investigated. In 30 anesthetized (pentobarbital) hamsters, the cremaster was prepared for intravital microscopy, and a pneumatic vessel occluder was placed around the aorta to vary blood pressure in the hindquarter of the animal. Intravenous infusion of NE (0.5 nmol/…
Impact of single-dose application of TGF-β, copper peptide, stanozolol and ascorbic acid in hydrogel on midline laparatomy wound healing in a diabeti…
2012
Despite numerous advances and improvements in surgical techniques the incidence of incisional hernias after laparotomy remains high. The aim of this study was to investigate possible effects of single application of ascorbic acid, stanozolol, a synthetic anabolic steroid, copper peptide and transforming growth factor-β (TGF-β) on laparotomy wound healing in an incisional wound model in diabetic mice. After diabetes induction with streptozotozin in Balb-c mice, midline laparatomies were carried out. Closure of the linea alba was followed by single-dose application of the agents dissolved in a hydrogel before skin closure. The functional outcome was assessed in terms of maximum tensile streng…
Postoperative continuous positive airway pressure to prevent pneumonia, re-intubation, and death after major abdominal surgery (PRISM): a multicentre…
2021
BackgroundRespiratory complications are an important cause of postoperative morbidity. We aimed to investigate whether continuous positive airway pressure (CPAP) administered immediately after major abdominal surgery could prevent postoperative morbidity.MethodsPRISM was an open-label, randomised, phase 3 trial done at 70 hospitals across six countries. Patients aged 50 years or older who were undergoing elective major open abdominal surgery were randomly assigned (1:1) to receive CPAP within 4 h of the end of surgery or usual postoperative care. Patients were randomly assigned using a computer-generated minimisation algorithm with inbuilt concealment. The primary outcome was a composite of…
Focal nodular hyperplasia-like lesions in patients with cavernous transformation of the portal vein: prevalence, MR findings and natural history.
2011
PURPOSE: To retrospectively investigate the prevalence, MR findings, natural history, and association with other hepatic lesions of focal nodular hyperplasia (FNH)-like lesions in a cohort of consecutive patients with cavernous transformation of the portal vein (CTPV). MATERIALS AND METHODS: This retrospective IRB-approved study comprised 58 patients (32 men, 26 women; average age, 50 years) with CTPV who underwent liver MR imaging between 2000 and 2008. MR images were assessed by two radiologists in consensus for the presence of (a) FNH-like lesions and other liver lesions, and (b) other imaging findings. Patients were assigned to a stable or progressive clinical course based on lesion cha…
