Sigma-rectum pouch (Mainz pouch II).
1993
A substantial modification of the classic technique of ureterosigmoidostomy is introduced in this article. To date, this procedure has been used in 47 patients. This article reviews the surgical technique of the antemesenterial splitting of the intestine at the recto-sigmoid junction which creates a pouch by subsequent side-to-side anastomosis.
Validation of the histologic risk model in a new cohort of patients with head and neck squamous cell carcinoma.
2010
Background: Half of the patients with head and neck squamous cell carcinoma (HNSCC) can be expected to fail therapy, indicating that more aggressive treatment is warranted for this group. We have developed a novel risk model that can become a basis for developing new treatment paradigms. Here we report on the performance of our model in a new multicenter cohort. Design: Eligible patients from 3 institutions (Montefiore Medical Center, University of Manitoba, and New York University Medical Center) were identified and pathology slides from their resection specimens were reviewed by Margaret Brandwein-Gensler; risk category was assigned as previously published. Kaplan-Meier analysis was perfo…
Orofacial dermoid cysts in pediatric patients : a review of 8 cases
2010
Objective: The aim was to analyze the clinical characteristics, treatment and outcome of 8 orofacial dermoid cysts (DC) in pediatric patients. Material and Methods: A retrospective observational study was made, reviewing the medical records with clinical diagnosis of dermoid cyst between 1987 and 2006 in the Children?s Maxillofacial Surgery Department of the Hospital Universitario La Fe, Valencia, Spain. The following data were collected: sex, age, location, size and duration of the lesion, treatment, length of follow-up, and recurrence. Results: Eight patients (3 girls and 5 boys) with a mean age of 2.7 years (range 0-12 years). Four DC were located in the oral area (3 sublingual and 1 lin…
Long-Term Followup of Children with Colon Conduit Urinary Diversion and Ureterosigmoidostomy
1977
Sixty-four children underwent colon conduit urinary diversion because of a neurogenic bladder owing to myelomeningocele and 39 children required a ureterosigmoidostomy because of bladder exstrophy. The average length of followup was 4.6 years after colon conduit and 5.6 years after ureterosigmoidostomy. Colon conduit diversion was secondary in 3 children and ureterosigmoidostomy was secondary in 5. Of the children with a colon conduit 9.4% and of those with ureterosigmoidostomy 12.8% had postoperative surgical complications. Late surgical complications were encountered after colon conduit in 14.5% and after ureterosigmoidostomy in 20%. Of the children with normal renal function preoperative…
Simultaneous appearance of leukemoid reaction and phlegmasia cerulea dolens
2012
A leukemoid reaction is an extreme form of reactive leukocytosis defined as granulocytic leukocytosis above 50 × 109/L produced by normal bone marrow, mostly in response to systemic infection or cancer. The mechanism as to how the haematopoetic system is altered to elevate production of myeloid cells is not known. A 69-year-old man presented with phlegmasia cerulea dolens caused by massive iliofemoral thrombosis. His workout at admission revealed absolute white blood cell count of 73.4 × 109/L, with neutrophil granulocyte of 68.5 × 109/L. The new increase in white blood cell count happened at day 5 after admission, when the haematoma of the anteromedial thigh was evacuated in general anaes…
Non-occlusive mesenteric Ischemia (NOMI) in Parkinsonâs disease: Case report
2017
Non-occlusive mesenteric ischemia (NOMI) is a severe pathological condition characterized by signs and symptoms of bowel obstruction, intestinal necrosis resulting from acute and/or chronic inadequate blood perfusion, in the absence of an organic vascular obstruction detectable by imaging techniques. A 64 years old man case with a history of Parkinsonâs disease in high-functioning levodopa treatment is presented. Clinical and radiological signs of intestinal obstruction were observed. He underwent surgical operation with total colectomy and terminal ileostomy for generalized secondary peritonitis due to perforation of sigmoid colon. Ischemic pancolitis was first suspected. In third post-o…
Incidence and prevalence of salivary gland tumours in Valparaiso, Chile
2014
Background : To determine the incidence and prevalence of salivary gland tumours in the province of Valparaíso, Chile. Material and Methods : Retrospective review of salivary gland tumours diagnosed between the years 2000 and 2011 from four local pathology services. Information on demographics and histopathology were retrieved from the medical records. Results : The study sample consisted of 279 salivary gland tumours. Prevalence and incidence rates per 100.000 persons were 15.4 and 2.51, respectively. Most of the neoplasms corresponded to benign tumours (70.3%). The most affected gland was the parotid gland. Pleomorphic adenoma was the most common benign tumour (53.8%) and mucoepidermoid c…
Activation of angiotensin II type 1 receptors and contractile activity in human sigmoid colon in vitro.
2015
We propose and validate a non-invasive method that enables accurate detection of the discharge times of a relatively large number of motor units during excitatory and inhibitory reflex stimulations. HDsEMG and intramuscular EMG (iEMG) were recorded from the tibialis anterior muscle during ankle dorsiflexions performed at 5%, 10%, and 20% of the maximum voluntary contraction (MVC) force, in 9 healthy subjects. The tibial nerve (inhibitory reflex) and the peroneal nerve (excitatory reflex) were stimulated with constant current stimuli. In total, 416 motor units were identified from the automatic decomposition of the HDsEMG. The iEMG was decomposed using a state-of-the-art decomposition tool a…
Pringle maneuver increases the risk of anastomotic leakage after colonic resection in rats.
2018
Abstract Background Many centers use the Pringle's maneuver during liver resections. Since this maneuver might impair healing of bowel anastomoses, we evaluated its influence on the healing of colonic anastomosis in rats. Methods Male Wistar rats underwent median laparotomy and sigmoid resection with end-to-end anastomosis under inhalation anesthesia. Thereafter, rats received a 25 minutes Pringle's maneuver (PM, group 1) or were kept under anesthesia for the same period of time (group 2). The anastomotic bursting pressure (BP) was measured on postoperative days (POD) 3, 6 and 9. Hematoxylin and Eosin (H&E) staining was used for histopathological evaluation of the anastomosis. The Mann-Whit…
Successful Endoscopic Resection of an Esophageal Metastasis from a Preceding Squamous-Cell Tonsillar Carcinoma
2005
This report describes the case of a 62-year-old man with tonsillar carcinoma who had undergone esophagectomy due to an esophageal metastasis. Subsequently, a second metastasis occurred in the residual esophagus, and he presented for evaluation for local endoscopic therapy. The initial upper endoscopy revealed a type IIa - c lesion at 21 cm from the incisors, within a segment suspicious for Barrett's mucosa. As part of the complex treatment approach in this patient, endoscopic resection of the lesion was carried out using the suck-and-cut technique with ligation. Histology showed that the lesion was a metastasis from a squamous-cell carcinoma, with focal infiltration of the upper submucosal …
