Intestinal leiomyositis is a suspected autoimmune disorder affecting the muscularis propria layer of the gastrointestinal tract and is a cause of chronic intestinal pseudo-obstruction in humans and animals. To characterize the clinical presentation, histopathologic features, and outcome of dogs with intestinal leiomyositis in an effort to optimize treatment and prognosis. Six client-owned dogs. Retrospective case series. Medical records were reviewed to describe signalment, clinicopathologic and imaging findings, histopathologic diagnoses, treatment, and outcome. All biopsy specimens were reviewed by a board-certified pathologist. Median age of dogs was 5.4 years (range, 15 months-9 years). Consistent clinical signs included vomiting (6/6), regurgitation (2/6), and small bowel diarrhea (3/6). Median duration of clinical signs before presentation was 13 days (range, 5-150 days). Diagnostic imaging showed marked gastric distension with dilated small intestines in 4/6 dogs. Full-thickness intestinal biopsies were obtained in all dogs by laparotomy. Histopathology of the stomach and intestines disclosed mononuclear inflammation, myofiber degeneration and necrosis, and fibrosis centered within the region of myofiber loss in the intestinal muscularis propria. All dogs received various combinations of immunomodulatory and prokinetic treatment, antimicrobial agents, antiemetics, and IV fluids, but none of the dogs showed a clinically relevant improvement with treatment. Median survival was 19 days after diagnosis (range, 3-270 days). Intestinal leiomyositis is a cause of intestinal pseudo-obstruction and must be diagnosed by full-thickness intestinal biopsy. This disease should be considered in dogs with acute and chronic vomiting, regurgitation, and small bowel diarrhea. Copyright © 2015 The Authors.

Closed duodenal loops may be made in dogs by ligatures placed just below the pancreatic duct and just beyond the duodenojejunal junction, together with a posterior gastro-enterostomy. These closed duodenal loop dogs die with symptoms like those of patients suffering from volvulus or high intestinal obstruction. This duodenal loop may simulate closely a volvulus in which there has been no vascular disturbance. Dogs with closed duodenal loops which have been washed out carefully survive a little longer on the average than animals with unwashed loops. The duration of life in the first instance is one to three days, with an average of about forty-eight hours. The dogs usually lose considerable fluid by vomiting and diarrhea. A weak pulse, low blood pressure and temperature are usually conspicuous in the last stages. Autopsy shows more or less splanchnic congestion which may be most marked in the mucosa of the upper small intestine. The peritoneum is usually clear and the closed loop may be distended with thin fluid, or collapsed, and contain only a small amount of pasty brown material. The mucosa of the loop may show ulceration and even perforation, but in the majority of cases it is intact and exhibits only a moderate congestion. Simple intestinal obstruction added to a closed duodenal loop does not modify the result in any manner, but it may hasten the fatal outcome. The liver plays no essential role as a protective agent against this poison, for a dog with an Eck fistula may live three days with a closed loop. A normal dog reacts to intraportal injection and to intravenous injection of the toxic substance in an identical manner. Drainage of this loop under certain conditions may not interfere with the general health over a period of weeks or months. Excision of the part of the duodenum included in this loop causes no disturbance. The material from the closed duodenal loops contains no bile, pancreatic juice, gastric juice, or split products from the food. It can be

Acute colonic pseudo-obstruction (ACPO), also known as Ogilvie’s syndrome, is a clinical syndrome characterised by gross dilation of the caecum and right hemicolon, which sometimes extends to the sigmoid colon and rectum in the absence of an anatomic lesion in the intestinal lumen. It is characterised by impaired propulsion of contents of the gastrointestinal tract, which results in a clinical picture of intestinal obstruction. A careful examination of the markedly distended colon can exclude several colonic pathologies, including mechanical obstruction and other causes of toxic megacolon. ACPO can sometimes predispose or mimic colonic volvulus, especially in geriatric patients. PMID:25716038

In a retrospective study the authors analyzed the clinical records of 199 children ages one month to 16 years hospitalized, with the diagnosis of intestinal ascariasis, in the Instituto Nacional de Pediatria of Mexico from 1984 to 1999. The purpose of the study was to evaluate the use of anthelmintics drugs as a risk factor of intestinal obstruction by A. lumbricoides. Two groups were made for the study: Group A (n = 66) of children who presented intestinal obstruction, Group B (n = 133) children with no complications. A comparative analysis of clinical data of both groups was made by means of chi square with Yates correction and a stratified analysis by means of chi square. Possible confusing elements were overcrowding, age and the use of antiparasitic drugs. The calculus of risk factors for intestinal obstruction by A. lumbricoides was done by means of contingency tables of 2 x 2 and odds ratio with an IC of 95%. The significant risk factors were included in a model of logistics regression with an impact variable consting in the presence or absence of intestinal obstruction in order to establish a multivariate model of predictive risk at level of significance of p < 0.05. Twenty-seven patients (40.90%) in group A (n = 66) were given anthelmintics medications prior to the intestinal obstruction: mebendazol, 14 (51-85%); two, albedazol (7.4%); eight, a non-specified anthelmintic (29.6%). In addition, an anthelmintic medication without a specified time of ingestion: two with mebendazol and one with piperazine (11.3%). In the case of mebendazol, the drug most frequently associated with intestinal obstruction, seven patients received it on the same day of the obstruction; five patients received it between one and seven days prior to the obstruction; two received it seven days prior to the complication. In the control group, only 7% had taken the anthelmintic one to seven days before the diagnosis of uncomplicated intestinal ascariasis diagnosis was made. With the step

Intraperitoneal foreign bodies such as retained surgical instruments can cause intestinal obstruction. However, intestinal obstruction due to transmural migration of foreign bodies has rarely been reported. Here, we report a case of intestinal obstruction due to a clinical thermometer which migrated from the bladder into the abdominal cavity. A 45-year-old man was admitted to our hospital with a one-year history of recurrent lower abdominal cramps. Two days before admission, the abdominal cramps aggravated. Intestinal obstruction was confirmed with upright abdominal radiography and computerized tomography scan which showed dilation of the small intestines and a thermometer in the abdominal cavity. Then laparotomy was performed. A scar was observed at the fundus of the bladder and a thermometer was adhering to the small bowels and mesentery which resulted in intestinal obstruction. Abdominal cramps were eliminated and defecation and flatus recovered soon after removal of the thermometer.

Lynch syndrome is an autosomal-dominant disorder caused by defective DNA mismatch repair (MMR) genes and is associated with increased risk of malignancies in multiple organs. Small-intestinal adenocarcinomas are common initial manifestations of Lynch syndrome. To define the incidence and characteristics of Lynch syndrome-related small-intestinal adenocarcinomas, meticulous familial and clinical histories were obtained from 195 patients with small-intestinal adenocarcinoma, and MMR protein immunohistochemistry, microsatellite instability, MLH1 methylation, and germline mutational analyses were performed. Lynch syndrome was confirmed in eight patients (4%), all of whom had synchronous/metachronous malignancies without noticeable familial histories. Small-intestinal adenocarcinomas were the first clinical manifestation in 37% (3/8) of Lynch syndrome patients, and second malignancies developed within 5 years in 63% (5/8). The patients with accompanying Lynch syndrome were younger (≤50 years; P=0.04) and more likely to have mucinous adenocarcinomas (P=0.003), and tended to survive longer (P=0.11) than those with sporadic cases. A meticulous patient history taking, MMR protein immunolabeling, and germline MMR gene mutational analysis are important for the diagnosis of Lynch syndrome-related small-intestinal adenocarcinomas. Identifying Lynch syndrome in patients with small-intestinal adenocarcinoma can be beneficial for the early detection and treatment of additional Lynch syndrome-related cancers, especially in patients who are young or have mucinous adenocarcinomas.

Intestinal pseudo-obstruction is considered to be one of the most frequent gastrointestinal manifestations of myasthenia gravis, accompanied by the presence of neoplasia of the thymus gland in the vast majority of the cases presented in the international literature. Despite the fact that myasthenia gravis has been implicated to be the cause of recurrent episodes of intestinal pseudo-obstruction, adhesive ileus has never been reported to complicate this - in any sense rare - condition. We present a unique case of a patient with myasthenia gravis, free of thymus neoplasia, who was submitted to emergency surgery due to the presence of extended adhesive ileus as a complication of chronic intestinal functional obstruction.

To observe the protective effect of glucagon-like peptide-2 (GLP-2) on the intestinal barrier of rats with obstructive jaundice and determine the possible mechanisms of action involved in the protective effect. Thirty-six Sprague-Dawley rats were randomly divided into a sham operation group, an obstructive jaundice group, and a GLP-2 group; each group consisted of 12 rats. The GLP-2 group was treated with GLP-2 after the day of surgery, whereas the other two groups were treated with the same concentration of normal saline. Alanine aminotransferase (ALT), total bilirubin, and endotoxin levels were recorded at 1, 3, 7, 10 and 14 d. Furthermore, on the 14(th) day, body weight, the wet weight of the small intestine, pathological changes of the small intestine and the immunoglobulin A (IgA) expressed by plasma cells located in the small intestinal lamina propria were recorded for each group. In the rat model, jaundice was obvious, and the rats' activity decreased 4-6 d post bile duct ligation. Compared with the sham operation group, the obstructive jaundice group displayed increased yellow staining of abdominal visceral serosa, decreased small intestine wet weight, thinning of the intestinal muscle layer and villi, villous atrophy, uneven height, fusion, partial villous epithelial cell shedding, substantial inflammatory cell infiltration and significantly reduced IgA expression. However, no significant gross changes were noted between the GLP-2 and sham groups. With time, the levels of ALT, endotoxin and bilirubin in the GLP-2 group were significantly increased compared with the sham group (P < 0.01). The increasing levels of the aforementioned markers were more significant in the obstructive jaundice group than in the GLP-2 group (P < 0.01). GLP-2 reduces intestinal mucosal injuries in obstructive jaundice rats, which might be attributed to increased intestinal IgA and reduced bilirubin and endotoxin.

The application value of small intestine decompression combined with oral feeding in the middle and late period of malignant small bowel obstruction was examined. A total of 22 patients with advanced malignant small bowel obstruction were included in the present study. An ileus tube was inserted via the nose under fluoroscopy into the obstructed small intestine of each patient. At the same time, the insertion depth the of the catheter was adjusted. When the catheter was blocked, small bowel selective angiography was performed to determine the location and cause of the obstruction and the extent of the obstruction, and to determine the length of the small intestine in the site of obstruction, and to select the variety and tolerance of enteral nutrition. We observed the decompression tube flow and ease of intestinal obstruction. In total, 20 patients were treated with oral enteral nutrition after abdominal distension, and 22 cases were treated by the nose to observe the drainage and the relief of intestinal obstruction. The distal end of the catheter was placed in a predetermined position. The symptoms of intestinal obstruction were relieved 1-4 days after decompression. The 22 patients with selective angiography of the small intestine showed positive X-ray signs: 18 patients with oral enteral nutrition therapy had improved the nutritional situation 2 weeks later. In 12 cases, where there was anal defecation exhaust, 2 had transient removal of intestinal obstruction catheter. In conclusion, this comprehensive treatment based on small intestine decompression combined with enteral nutrition is expected to become a new therapeutic approach and method for the treatment of patients with advanced tumor small bowel obstruction.

ENT patients with obstructive sleep apnea syndrome have a tendency of collapsing the upper airways in addition to anatomical obstacles. Obstructive sleep apnea syndrome is related to the increased risk of difficult airway and also increased perioperative complications. In order to identify these patients in the preoperative period, the STOP Bang questionnaire has been highlighted because it is summarized and easy to apply. Evaluate through the STOP Bang questionnaire whether patients undergoing ENT surgery with a diagnosis of obstructive sleep apnea syndrome have a higher risk of complications, particularly the occurrence of difficult airway. Measurements of anatomical parameters for difficult airway and questionnaire application for clinical prediction of obstructive sleep apnea syndrome were performed in 48 patients with a previous polysomnographic study. The sample detected difficult airway in about 18.7% of patients, all of them with obstructive sleep apnea syndrome. This group had older age, cervical circumference > 40cm, ASA II and Cormack III/IV. Patients with obstructive sleep apnea syndrome had higher body mass index, cervical circumference, and frequent apnea. In subgroup analysis, the group with severe obstructive sleep apnea syndrome showed a significantly higher SB score compared to patients without this syndrome or with a mild/moderate obstructive sleep apnea syndrome. The STOP Bang questionnaire was not able to predict difficult airway and mild obstructive sleep apnea syndrome, but it identified marked obstructive sleep apnea syndrome. All patients with difficult airway had moderate and marked obstructive sleep apnea syndrome, although this syndrome did not involve difficult airway. The variables Cormack III/IV and BMI greater than 35 Kg.m -2 were able to predict difficult airway and obstructive sleep apnea syndrome, respectively.

Obstructive sleep apnoea/hypopnoea syndrome in adults with Down syndrome

PubMed Central

2016-01-01

Key points Adults with Down syndrome are predisposed to obstructive sleep apnoea/hypopnoea syndrome (OSAHS) due to overlap between the Down syndrome phenotype and OSAHS risk factors. The prevalence of OSAHS in adults with Down syndrome is estimated at 35–42%. This is up to ten-times higher than in the general adult population. Symptoms of OSAHS, including behavioural and emotional disturbances as well as standard symptoms such as sleepiness, should be monitored as part of regular health surveillance in adults with Down syndrome. There is evidence that the use of continuous positive airway pressure (CPAP) therapy in adults with Down syndrome and comorbid OSAHS can lead to significant improvements in subjective sleepiness, behaviour and cognitive function, though further large-scale trials are required. Educational aims To discuss the relationship between the phenotypic features of Down syndrome and the risk factors for obstructive sleep apnoea/hypopnoea syndrome (OSAHS). To examine the prevalence of OSAHS in adults with Down syndrome. To review recent research into the effectiveness of treatment of OSAHS in adults with Down syndrome using continuous positive airway pressure (CPAP) therapy. Obstructive sleep apnoea/hypopnoea syndrome (OSAHS) is characterised by repeated cycles of upper airway obstruction during sleep, leading to diurnal symptoms. Individuals with Down syndrome are predisposed to OSAHS due to overlap between the Down syndrome phenotype and OSAHS risk factors. Recent large studies using subjective and objective measures estimate that OSAHS affects around 40% of adults with Down syndrome, in contrast to 2–4% of the general adult population. The “double-hit” of comorbid Down syndrome and OSAHS may accelerate cognitive decline in adults with Down syndrome. However, with the appropriate care and support, OSAHS can be treated effectively in this group using continuous positive airway pressure (CPAP) therapy, improving daytime function and behaviour

Partial obstruction of the small intestine causes obvious hypertrophy of smooth muscle cells and motility disorder in the bowel proximate to the obstruction. To identify electric remodeling of hypertrophic smooth muscles in partially obstructed murine small intestine, the patch-clamp and intracellular microelectrode recording methods were used to identify the possible electric remodeling and Western blot, immunofluorescence and immunoprecipitation were utilized to examine the channel protein expression and phosphorylation level changes in this research. After 14 days of obstruction, partial obstruction caused obvious smooth muscle hypertrophy in the proximally located intestine. The slow waves of intestinal smooth muscles in the dilated region were significantly suppressed, their amplitude and frequency were reduced, whilst the resting membrane potentials were depolarized compared with normal and sham animals. The current density of voltage dependent potassium channel (KV) was significantly decreased in the hypertrophic smooth muscle cells and the voltage sensitivity of KV activation was altered. The sensitivity of KV currents (IKV) to TEA, a nonselective potassium channel blocker, increased significantly, but the sensitivity of IKv to 4-AP, a KV blocker, stays the same. The protein levels of KV4.3 and KV2.2 were up-regulated in the hypertrophic smooth muscle cell membrane. The serine and threonine phosphorylation levels of KV4.3 and KV2.2 were significantly increased in the hypertrophic smooth muscle cells. Thus this study represents the first identification of KV channel remodeling in murine small intestinal smooth muscle hypertrophy induced by partial obstruction. The enhanced phosphorylations of KV4.3 and KV2.2 may be involved in this process.

Several clinical and experimental studies have shown that obstructive jaundice delays wound healing. Growth hormone may prevent delayed wound healing, since it has effects on the release of mediators in jaundice, as well as increasing the protein synthesis. Forty male Wistar rats were allocated to four groups: Group I (n=10): intestinal anastomosis to normal small bowel, Group II (n=10): intestinal anastomosis to normal small bowel followed by growth hormone therapy (2mg/kg/day, subcutaneously), Group III (n=10): intestinal anastomosis to obstructive jaundice rat's small bowel, Group IV (n=10): intestinal anastomosis to obstructive jaundice rat's small bowel followed by growth hormone therapy at the same dosage The animals were observed for seven days then killed. Intraabdominal adhesions, anastomotic complications and anastomotic bursting pressures were recorded and tissue samples from the anastomotic site were obtained to measure hydroxyproline levels and for histopathologic examination. Growth hormone had a beneficial effect on the healing of intestinal anastomosis in both jaundiced and non-jaundiced rats. This was demonstrated by clinical and mechanical parameters such as a significant increase in anastomotic bursting pressure, hydroxyproline content and histopathological scores. Growth hormone reverses the adverse effects of obstructive jaundice on small bowel anastomotic healing. It can be hypothesized that this effect is due to augmentation of insulin-like growth factors, protection of hepatocytes, enhancement of intestinal epithelization, and reversal of the resultant malnutritional state caused by growth hormone in obstructive jaundice.

Time-course evaluation of intestinal structural disorders in a porcine model of intra-abdominal hypertension by mechanical intestinal obstruction

2018-01-01

Background A mechanical intestinal obstruction (MIO) can generate intraabdominal hypertension (IAH) that is life threatening. The intestines are very sensitive to IAH since the low splanchnic perfusion causes intestinal hypoxia, local acidosis and bacterial translocations. This may lead to acute intestinal distress syndrome (AIDS). The identification of intestinal injuries during IAH and its correlation with clinical parameters as the abdominal perfusion pressure (APP), the gastric intramucosal pH (pHi) and lactic acid (Lc) are still unknown. This study aimed to evaluate the sequence of intestinal histopathological findings in an MIO model and to analyze potential relationships with parameters currently used in clinical practice (APP, pHi and Lc). Material and methods Twenty pigs were divided into three groups: a control group (n = 5) and two experimental groups with 20 mmHg (G1, n = 10) and 30 mmHg (G2, n = 5) of IAH by MIO. The pressures were maintained for 3 hours, except in 5 animals in G1 where it was maintained for 5 hours. The APP, pHi and LA were recorded and biopsies of the terminal ileum were taken every 30 minutes in all groups. The intestinal damage was graded according to the Park Score. Results Intestinal injuries were found in 42.9% of pigs in the experimental groups. The lesions were independent of the level and duration of IAH. Although APP and pHi were slightly lower in injured animals (I +) of G1 and G2, there were no significant differences among those uninjured (I-). Lc was significantly increased in all I+ pigs from the onset of IAH. Conclusion The IAH by MIO causes intestinal lesions from the first 30 minutes with concurrent decreases in APP and pHi and increases in Lc. Lc could be the best clinical parameter related to intestinal damages with a clear difference between I + and I- animals. PMID:29357386

To investigate the prevalence of obstructive sleep apnoea syndrome in patients with primary open-angle glaucoma. Case series. School of Medicine, Düzce University, Turkey. Twenty-one consecutive primary open-angle glaucoma patients (12 females and 9 males) who attended the out-patient clinic of the Department of Ophthalmology between July 2007 and February 2008 were included in this study. All patients underwent polysomnographic examination. The prevalence of obstructive sleep apnoea syndrome was 33.3% in patients with primary open-angle glaucoma; the severity of the condition was mild in 14.3% and moderate in 19.0% of the subjects. The age (P=0.047) and neck circumference (P=0.024) in patients with obstructive sleep apnoea syndrome were significantly greater than those without the syndrome. Triceps skinfold thickness in glaucomatous obstructive sleep apnoea syndrome patients reached near significance versus those without the syndrome (P=0.078). Snoring was observed in all glaucoma cases with obstructive sleep apnoea syndrome. The intra-ocular pressure of patients with primary open-angle glaucoma with obstructive sleep apnoea syndrome was significantly lower than those without obstructive sleep apnoea syndrome (P=0.006 and P=0.035 for the right and left eyes, respectively). There was no significant difference in the cup/disc ratio and visual acuity, except visual field defect, between primary open-angle glaucoma patients with and without obstructive sleep apnoea syndrome. Although it does not provide evidence for a cause-effect relationship, high prevalence of obstructive sleep apnoea syndrome in patients with primary open-angle glaucoma in this study suggests the need to explore the long-term results of coincidence, relationship, and cross-interaction of these two common disorders.

A 65-year-old woman with a history of pylorus-preserving gastrectomy(PPG)for early gastric cancer visited our hospital because of vomiting. Gastrointestinal endoscopy revealed a large bezoar in the anastomotic site of the stomach. Because the bezoar was too large to be collected orally, the dissolution therapy with taking Coca-Cola®was continued. On the 3rd day after hospitalization, she felt acute abdominal pain with vomiting. Computed tomography revealed intestinal obstruction by a mass with air bubbles inside in the ileum. Emergency operation was performed under a diagnosis of intestinal obstruction due to the bezoar. The black brown bezoar sized 80×35×30mm was extracted through an ileotomy. The delayed gastric empty is considered to involve in the bezoar formation. Therefore, the appropriate education of diet and periodic endoscopic screening are necessary for patients with large amounts of gastric residues especially after PPG. In the dissolution therapy, physicians need to be careful of intestinal obstruction by a bezoar.

To evaluate the role of the small intestinal decompression tube (SIDT) and Gastrografin in the treatment of early postoperative inflammatory small bowel obstruction (EPISBO). Twelve patients presented EPISBO after abdominal surgery in our department from April 2011 to July 2012. Initially, nasogastric tube decompression and other conventional conservative treatment were administrated. After 14 days, obstruction symptom improvement was not obvious, then the SIDT was used. At the same time, Gastrografin was injected into the small bowel through the SIDT in order to demonstrate the site of obstruction of small bowel and its efficacy. In 11 patients after this management, obstruction symptoms disappeared, bowel function recovered within 3 weeks, and oral feeding occurred gradually. Another patient did not pass flatus after 4 weeks and was reoperated. After postoperative follow-up of 6 months, no case relapsed with intestinal obstruction. For severe and long course of early postoperative inflammatory intestinal obstruction, intestinal decompression tube plus Gastrografin is safe and effective, and can avoid unnecessary reoperation.

Intestinal obstruction is associated with significant morbidity and mortality. Scientific assessment of the cause, site of obstruction, appropriate correction of the fluid deficit and electrolyte imbalance with preoperative stabilization of blood gases is ideal as a preoperative workup. Placement of a preoperative epidural catheter especially in the thoracic interspace takes care of perioperative pain and stress reduction. Intraoperative management by controlled general anesthesia administering a relative high inspired fraction of oxygen with invasive monitoring in selected sick cases is mandatory. Preoperative monitoring and stabilizing raised intra-abdominal pressure reduces morbidity. Caution should be exercised during opening and closure of abdomen to avoid cardiorespiratory ill effects. There should be an emphasis on avoiding hypothermia. The use of nonsteroidal anti-inflammatory drugs may worsen sick, fragile patients. The use of sugammadex rather than neostigmine will obscure certain controversies in the healing of intestinal anastomotic site. Replacement of blood loss continued correction of fluids and electrolytes with possible postoperative mechanical ventilation in sick cases may improve outcomes in these patients.

Intestinal radiation syndrome: sepsis and endotoxin

Rats were whole-body irradiated with 8-MeV cyclotron-produced neutrons and /sup 137/Cs ..gamma.. rays to study the role of enteric bacteria and endotoxin in the intestinal radiation syndrome. Decrease in intestinal weight was used as an index of radiation-induced breakdown of the mucosa. Neutron and ..gamma..-ray doses that were sublethal for intestinal death resulted in a dose-dependent decrease in intestinal weight, reaching minimal values 2 to 3 days after exposure, followed by recovery within 5 days after irradiation. Neutron and photon doses that caused intestinal death resulted in greater mucosal breakdown with little or no evidence of mucosal recovery. The presencemore » of fluid in the intestine and diarrhea, but not bacteremia or endotoxemia, were related to mucosal breakdown and recovery. Neither sepsis nor endotoxin could be detected in liver samples taken at autopsy from animals which died a short time earlier from intestinal injury. These results suggest that overt sepsis and endotoxemia do not play a significant role in the intestinal radiation syndrome.« less

Bacterial translocation induced by intestinal obstruction is suggested to be due to increased intestinal luminal volume, leading to intestinal overgrowth with certain enteric microorganisms and intestinal mucosal damage. If this suggestion is true, maintenance of intestinal mucosal integrity by a cytoprotective agent, a-tocopherol, and inhibition of gastrointestinal secretions by octreotide should decrease the incidence of bacterial translocation and extent of mucosal injury due to intestinal obstruction. Complete intestinal obstruction was created in the distal ileum of male Wistar Albino rats by a single 3-0 silk suture. The animals received subcutaneous injections of 1 ml of physiologic saline (group 1) (PS 24) and 1 ml of saline containing octreotide acetate (100 micrograms/kg) (group 2) (OC 24), at 0, 12 and 24 hours of obstruction. In group 3 (PS 48) and group 4 (OC 48), the rats were treated with subcutaneous physiologic saline (1 ml) and octreotide acetate (100 micrograms/kg), respectively, beginning at the time of obstruction and every 12 hours for 48 hours. The rats in group 5 (Toc 24), were pretreated with intramuscular a-tocopherol 500 mg/kg on day 1 and 8, and underwent laparotomy on day 9. A third dose of a-tocopherol was injected at the time of obstruction on day 9 and no treatment was given thereafter. We tested the incidence of bacterial translocation in systemic organs and circulation and evaluated the histopathological changes in all groups. Treatment with octreotide acetate was found to be ineffective in reducing the incidence of translocation, with no histopathological improvement. Mucosal damage scores, on the other hand, in the a-tocopherol group were statistically less than those in the octreotide and control groups (p < 0.05). Additionally, a-tocopherol treatment decreased the incidence of organ invasion with translocating bacteria, although this difference did not reach statistical significance.

Obstructive sleep apnea syndrome is a common problem among children and is recognized as a cause of significant medical morbidity. Since the 1980s, it has been suggested that obstructive sleep apnea syndrome is a risk factor for growth failure in children. In many cases, it has been shown that growth failure is reversible once the obstructive sleep apnea syndrome is resolved. The objectives of this study were to analyze and compare growth failure prevalence in a Mediterranean population of children with obstructive sleep apnea syndrome and healthy children matched in age and sex, and to assess the effectiveness of tonsillectomy and adenoidectomy in resolving growth retardation. We compared 172 children with obstructive sleep apnea syndrome (apnea-hypopnea index ≥ 3) who had undergone tonsillectomy and adenoidectomy with 172 healthy controls in terms of key anthropometric parameters. Most of the criteria used for growth failure were higher to a statistically significant degree in the study group vs the control group: height-for-age ≤ 3rd percentile (7.56% vs 2.91%; p = 0.044), weight-for-age ≤ 5th percentile (9.30% vs 2.33%; p = 0.005), weight-for-age ≤ 3rd percentile (8.14% vs 2.33%; p = 0.013) and height and/or weight for-age ≤ 5th percentile (13.95% vs 5.81%; p = 0.009). The height-for-age ≤ 5th percentile was almost at the limit of statistical significance (8.72% for the study group vs 4.65% for the control group; p = 0.097). At one-year post-surgery follow-up, 10 of 15 children with height-for-age ≤ 5th percentile had achieved catch-up growth (66.6%), and 14 of 24 children with height- and/or weight-for-age ≤ 5th percentile had normalized growth (58.33%). For children with failure to thrive or who have growth failure, physicians should consider the possibility of obstructive sleep apnea. A significant number of children with obstructive sleep apnea concurrent with growth failure could benefit from

Distal intestinal obstruction syndrome (DIOS) and constipation in cystic fibrosis (CF) are conditions associated with impaction and/or obstruction by abnormally viscid mucofaecal material within the intestinal lumen. Dehydration has been proposed as a risk factor for DIOS and constipation in CF. The study primarily aimed to determine whether warmer ambient temperature and lower rainfall are risk factors for DIOS and constipation in CF. Hospitalisations for DIOS (incomplete or complete) and/or constipation were retrospectively identified (2000-2012). Genotype, phenotype, temperatures and rainfall data (for the week preceding and season of hospitalisation) were collected. Twenty-seven DIOS (59.3% incomplete; 40.7% complete) and 44 constipation admissions were identified. All admitted patients were pancreatic insufficient. Meconium ileus was significantly more likely in DIOS than constipation (64.7% vs. 33.3%; P = 0.038) and in complete than incomplete DIOS (100% vs. 57.1%; P = 0.04). The maximum temperature of the week before DIOS admission (mean (standard deviation) = 28.0 (5.8) °C) was significantly higher than the maximum temperature of the season of admission (25.2 (3.4) °C; P = 0.002). Similarly, the maximum temperature of the week before hospitalisation for constipation (mean (standard deviation) = 27.9 (6.3) °C) was significantly warmer compared with the season of admission (24.0 (4.1) °C; P < 0.0001). There were no significant differences between levels of rainfall during the week before hospitalisation and the season of admission for both DIOS and constipation. Relatively high ambient temperature may play a role in the pathogenesis of DIOS and constipation in CF. © 2016 The Authors Journal of Paediatrics and Child Health © 2016 Paediatrics and Child Health Division (Royal Australasian College of Physicians).

Intestinal obstruction and constipation are common conditions in patients with advanced neoplasms. Diatrizoate Meglumine has been used in the management of both these conditions without good quality evidence of its effectiveness and safety. This audit aimed to assess the usage, effectiveness and adverse effects of Diatrizoate Meglumine for intestinal obstruction and constipation in patients with advanced neoplasms. A retrospective chart review was undertaken. Descriptive statistics were utilised. All patients with known advanced neoplasms admitted to Mater Health Services and St Vincent's Private Hospital Brisbane between January 2013 and October 2015; who were administered Diatrizoate Meglumine were included. Seventy-one patients received Diatrizoate Meglumine. The most common diagnoses were ovarian or primary peritoneal neoplasms (33.8%). Diatrizoate Meglumine was most commonly used for intestinal obstruction (59.2%). The median dose used per patient episode was 50 mL (range: 15-500 mL). Thirty-two patients (45%) had imaging 4-24 h post-dose with Diatrizoate Meglumine being present in the large intestine in 75% of these images. Intestinal obstruction or constipation resolved in 90% of patients post-dose. Most clinicians used 50 mL of Diatrizoate Meglumine as a single dose and repeated imaging after 4-24 h. Diatrizoate Meglumine was well tolerated and may be effective in resolving intestinal obstruction and constipation in patients with advanced neoplasms. Quality controlled studies are needed to further guide the use of Diatrizoate Meglumine in intestinal obstruction and constipation in patients with advanced neoplasms.

To determine the value of bowel sounds analysis using an electronic stethoscope to support a clinical diagnosis of intestinal obstruction. Subjects were patients who presented with a diagnosis of possible intestinal obstruction based on symptoms, signs, and radiological findings. A 3M™ Littmann(®) Model 4100 electronic stethoscope was used in this study. With the patients lying supine, six 8-second recordings of bowel sounds were taken from each patient from the lower abdomen. The recordings were analysed for sound duration, sound-to-sound interval, dominant frequency, and peak frequency. Clinical and radiological data were reviewed and the patients were classified as having either acute, subacute, or no bowel obstruction. Comparison of bowel sound characteristics was made between these subgroups of patients. In the presence of an obstruction, the site of obstruction was identified and bowel calibre was also measured to correlate with bowel sounds. A total of 71 patients were studied during the period July 2009 to January 2011. Forty patients had acute bowel obstruction (27 small bowel obstruction and 13 large bowel obstruction), 11 had subacute bowel obstruction (eight in the small bowel and three in large bowel) and 20 had no bowel obstruction (diagnoses of other conditions were made). Twenty-five patients received surgical intervention (35.2%) during the same admission for acute abdominal conditions. A total of 426 recordings were made and 420 recordings were used for analysis. There was no significant difference in sound-to-sound interval, dominant frequency, and peak frequency among patients with acute bowel obstruction, subacute bowel obstruction, and no bowel obstruction. In acute large bowel obstruction, the sound duration was significantly longer (median 0.81 s vs 0.55 s, P = 0.021) and the dominant frequency was significantly higher (median 440 Hz vs 288 Hz, P = 0.003) when compared to acute small bowel obstruction. No significant difference was seen

Bile acids stimulate intestinal epithelial proliferation in vitro. We sought to investigate the role of the bile acid receptor TGR5 in the protection of intestinal epithelial proliferation in obstructive jaundice. Intestinal tissues and serum samples were obtained from patients with malignant obstructive jaundice and from bile duct ligation (BDL) rats. Intestinal permeability and morphological changes in the intestinal mucosa were observed. The functions of TGR5 in cell proliferation in intestinal epithelial injury were determined by overexpression or knockdown studies in Caco-2 and FHs 74 Int cells pretreated with lipopolysaccharide (LPS). Internal biliary drainage was superior to external biliary drainage in recovering intestinal permeability and mucosal histology in patients with obstructive jaundice. In BDL rats, feeding of chenodeoxycholic acid (CDCA) decreased intestinal mucosa injury. The levels of PCNA, a marker of proliferation, increased in response to CDCA feeding and were paralleled by elevated TGR5 expression. CDCA upregulated TGR5 expression and promoted proliferation in Caco-2 and FHs 74 Int cells pretreated with LPS. Overexpression of TGR5 resulted in increased PCNA, cell viability, EdU incorporation, and the proportion of cells in S phase, whereas knockdown of TGR5 had the opposite effect. Our data indicate that bile acids promote intestinal epithelial cell proliferation and decrease mucosal injury by upregulating TGR5 expression in obstructive jaundice. Copyright © 2016 Elsevier Inc.

Intestinal obstruction prompts luminal dilation and wall remodeling proximal to the site of obstruction. Studies on temporal and spatial morphomechanical remodeling are needed for comprehending the pathophysiology of acute intestinal obstruction. The aim was to estimate the no-load and zero-stress morphomechanical properties in circumferential and longitudinal direction at 0, 6, 12, 24, 36, and 48 h after complete intestinal obstruction. Obstruction of the distal ileum was created surgically by placement of a polyethylene ring for up to 48 h in 30 rats. Sham and normal groups were also studied (n = 12). Five 6 cm-long intestinal segments proximal to the obstruction site were used for histological, morphometric and mechanical analysis at the designated times. Morphomechanical changes were huge but only subtle changes were observed between the 5 segments during the obstruction period. Due to dilation, the serosal length and mucosal length increased continuously from 6 to 48 h (p < 0.001). The wall area increased at 24 h and beyond (p < 0.001), demonstrating tissue growth. The opening and bending angle decreased to minimum values at 24 h where after the opening angle increased and the bending angle returned to pre-obstruction levels. For the residual stretch ratios and the position of the neutral axis the turning point was found after 24 h. Histologically, the thickness and area of most wall layers were quite stable for the first 12 h but with an increase at the 24 h time point that continued to the 48 h time point. The most pronounced change was found for the circumferential muscle layer (p < 0.05). Analysis of picrosirius red stained slides showed that submucosal type 3 collagen fraction increased significantly (p < 0.001), whereas the fraction of type 1 collagen decreased (p < 0.001). In conclusion, pronounced time-dependent morphomechanical remodeling was found. The obstructed intestine went from dilation remodeling to growth remodeling

Duodenal Obstruction Caused by Acute Appendicitis with Intestinal Malrotation in a Child.

In patients with intestinal malrotation, the diagnosis of acute appendicitis can be difficult due to atypical presentation. Duodenal obstruction caused by acute appendicitis with the presence of malrotation has rarely been reported in children. We report the case of a 14-year-old male patient with bilious vomiting and abdominal distension. A diagnosis could not be made by computed tomography, ultrasonography, or endoscopy. We observed a dilated stomach and malrotation in laparotomy. The caecum was in the right upper quadrant, and an inflamed appendix was located in the subhepatic region. After the appendectomy, the cecum was mobilized and fixed in the right lower quadrant. In children with intestinal malrotation, acute appendicitis can present as duodenal obstruction without abdominal pain, and standard imaging methods can miss the correct diagnosis.

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is characterized by bladder distension without urinary tract obstruction, decreased or absent intestinal peristalsis and microcolon. Although the definitive cause remains unknown, changes in the ACTG2 gene are thought to be responsible for the intestinal and bladder hypoperistalsis. This female newborn with MMIHS had a c.532C>A /p.Arg178Ser heterozygous de novo mutation detected in the ACTG2 gene. Normal immature ganglion cells, normal calretinin punctate positivity, maintence of smooth muscle actin immunoreactivity, and decreased numbers of interstitial cells of Cajal(ICCs) were detected. This previously unreported c.532C>A /p.Arg178Ser heterozygous de novo mutation in the ACTG2 gene may lead to a severe form of MMIHS.

OBJECTIVE: Obstructive sleep apnea syndrome is characterized by repetitive obstruction of the upper airways, and it is a risk factor for cardiovascular diseases. There have been several studies demonstrating low levels of nitric oxide in patients with obstructive sleep apnea syndrome compared with healthy controls. In this study, we hypothesized that reduced nitric oxide levels would result in high arginase activity. Arginase reacts with L-arginine and produces urea and L-ornithine, whereas L-arginine is a substrate for nitric oxide synthase, which produces nitric oxide. METHODS: The study group consisted of 51 obstructive sleep apnea syndrome patients (M/F: 43/8; mean age 49±10 years of age) and 15 healthy control subjects (M/F: 13/3; mean age 46±14 years of age). Obstructive sleep apnea syndrome patients were divided into two subgroups based on the presence or absence of cardiovascular disease. Nitric oxide levels and arginase activity were measured via an enzyme-linked immunosorbent assay of serum samples. RESULTS: Serum nitric oxide levels in the control subjects were higher than in the obstructive sleep apnea patients with and without cardiovascular diseases (p<0.05). Arginase activity was significantly higher (p<0.01) in obstructive sleep apnea syndrome patients without cardiovascular diseases compared with the control group. Obstructive sleep apnea syndrome patients with cardiovascular diseases had higher arginase activity than the controls (p<0.001) and the obstructive sleep apnea syndrome patients without cardiovascular diseases (p<0.05). CONCLUSION: Low nitric oxide levels are associated with high arginase activity. The mechanism of nitric oxide depletion in sleep apnea patients suggests that increased arginase activity might reduce the substrate availability of nitric oxide synthase and thus could reduce nitric oxide levels.

Intestinal polyposis syndromes, such as familial adenomatous polyposis (FAP) and Cowden's syndrome, are often associated with extraintestinal manifestations, and while many of these manifestations are benign, malignant extraintestinal manifestations, such as differentiated thyroid cancers, do occur. Although differentiated thyroid cancers (ie, papillary and follicular thyroid carcinomas) are associated with multiple syndromes, they are most commonly associated with intestinal polyposis syndromes. In the general population, the probability of developing thyroid cancer by age 65 years is only .5%. However, 1% to 2% of patients with FAP develop papillary thyroid carcinoma, the most common extraintestinal malignancy in patients with FAP. Also, up to 10% of patients with Cowden's syndrome will develop follicular thyroid carcinoma. The purpose of this review was to provide an overview of FAP, Cowden's syndrome, and Peutz-Jeghers syndrome, to discuss in detail the associations between intestinal polyposis syndromes and differentiated thyroid cancers, and to provide suggestions for screening and managing these diseases.

Systemic inflammatory response syndrome (SIRS) is an uncommon but severe complication in surgical patients. While SIRS is well known, it is poorly described in the pediatric population. The goal of this study was to describe the incidence of profound SIRS following non-emergent intestinal surgery in children and to identify potential risk factors. A retrospective review was conducted for patients 0-19 years of age following intestinal surgery and/or lysis of adhesions from 01/01/1999-02/28/2012. Children were excluded for preoperative instability or frank bowel perforation. Patients were then placed in a post-operative SIRS or non-SIRS group as defined by the 2005 International Pediatric Sepsis Consensus Conference Guidelines (6. B. Goldstein, B. Giroir, A. Randolph, and Sepsis International Consensus Conference on Pediatric, 'International Pediatric Sepsis Consensus Conference: Definitions for Sepsis and Organ Dysfunction in Pediatrics', Pediatr Crit Care Med, 6 (2005), 2-8.). SIRS was identified in 17 of the 381 patients. Logistic regression analysis was performed and showed heart disease, kidney disease, PN dependence, and intestinal obstruction to be predictive of post-operative SIRS. This study represents one of the first reports to identify a previously poorly described process of significant SIRS after intestinal surgery in children. Both systemic organ failure and intestinal dysfunction are strong risk factors for post-operative SIRS in children. Potentially, these pre-existing conditions may lead to disruption of normal intestinal flora or barrier function, which in turn may predispose these children to dramatic SIRS episodes after intestinal surgery. Understanding how these factors lead to SIRS will be critical to developing prevention strategies. © 2013 Elsevier Inc. All rights reserved.

Short bowel syndrome is a clinical entity that includes loss of energy, fluid, electrolytes or micronutrient balance because of inadequate functional intestinal length. This case report demonstrates the case of a woman who compensated for short bowel syndrome through intestinal adaptation, which is a complex process worthy of further investigation for the avoidance of dependence on total parenteral nutrition and of intestinal transplantation in such patients.

Background & Aims Chronic intestinal pseudo-obstruction (CIPO) is characterized by severe intestinal dysmotility that mimicks a mechanical sub-occlusion with no evidence of gut obstruction. We searched for genetic variants associated with CIPO to increase our understanding of its pathogenesis and indentify potential biomarkers. Methods We performed whole-exome sequencing of genomic DNA from patients with familial CIPO syndrome. Blood and lymphoblastoid cells were collected from patients and controls (individuals without CIPO); levels of mRNA and proteins were analyzed by quantitative reverse transcription PCR, immunoblot, and mobility shift assays. cDNAs were transfected into HEK293 cells. Expression of rad21 was suppressed in zebrafish embryos using a splice-blocking morpholino (rad21a MO). Gut tissues were collected and analyzed. Results We identified a homozygous mutation (p.622, encodes Ala>Thr) in RAD21 in patients from a consanguineous family with CIPO. Expression of RUNX1, a target of RAD21, was reduced in cells from patients with CIPO compared with controls. In zebrafish, suppression of rad21a reduced expression of runx1; this phenotype was corrected by injection of human RAD21 mRNA, but not with the mRNA from the mutated p.622 allele. rad21a MO zebrafish had delayed intestinal transit and greatly reduced numbers of enteric neurons, similar to patients with CIPO. This defect was greater in zebrafish with suppressed expression of ret and rad21, indicating their interaction in regulation of gut neurogenesis. The promoter region of APOB bound RAD21 but not RAD21 p.622 Ala>Thr; expression of wild-type RAD21 in HEK293 cells repressed expression of APOB, compared with control vector. The gut-specific isoform of APOB (APOB48) is overexpressed in sera from patients with CIPO who carry the RAD21 mutation. APOB48 is also overexpressed in sporadic CIPO in sera and gut biopsies. Conclusions Some patients with CIPO carry mutations in RAD21 that disrupt the ability of

Metabolic syndrome comprises a cluster of related disorders that includes obesity, glucose intolerance, insulin resistance, dyslipidemia, and fatty liver. Recently, gut-derived chronic endotoxemia has been identified as a primary mediator for triggering the low-grade inflammation responsible for the development of metabolic syndrome. In the present study we examined the role of the small intestinal brush-border enzyme, intestinal alkaline phosphatase (IAP), in preventing a high-fat-diet-induced metabolic syndrome in mice. We found that both endogenous and orally supplemented IAP inhibits absorption of endotoxin (lipopolysaccharides) that occurs with dietary fat, and oral IAP supplementation prevents as well as reverses metabolic syndrome. Furthermore, IAP supplementation improves the lipid profile in mice fed a standard, low-fat chow diet. These results point to a potentially unique therapy against metabolic syndrome in at-risk humans.

Small intestinal obstruction by remnants of the omphalomesenteric duct: findings on contrast enema.

2000-03-01

We reviewed the contrast enema examinations and medical records of six patients with small intestinal obstruction due to omphalomesenteric duct remnant to evaluate for characteristic imaging findings. In five out of the six patients the point of obstruction was demonstrated on the enema; in three patients, the characteristic "beak" of a volvulus was seen, either in the terminal ileum or cecum. In three patients, there was medial deviation of the cecum. The characteristic radiographic features of volvulus at the cecum or terminal ileum and medial deviation of the cecum should suggest persistence of an omphalomesenteric duct remnant as the etiology of obstruction in a child less than 2 years of age. The appearance of omphalomesenteric duct remnant obstruction on enema examination, though not specific, is characteristic and should be familiar to pediatric radiologists.

The present study describes the difficulties encountered in the diagnostic process and treatment of intestinal obstruction developed by patients with advanced abdominal neoplasia. This unicentric and retrospective study evaluates patients suffering from intestinal occlusion operated on at the First Surgical Clinic of the Oncology Institute in Bucharest, over a period of 4 years (2010 - 2013). Of these, 61 cases in which the occlusion occurred on the background of an advanced abdominal neoplasia were selected. We considered as advanced those cases of abdominal cancer where curative oncologic treatment is no longer possible due to the evolution stage. The random selection of the study period, the introduction of all the patients identified with this type of pathology, as well as the concentration of advanced abdominal neoplasia at the Oncology Institute in Bucharest are the elements that allow us to state that the results of this study are representative. Particularities related to the clinical aspects of the intestinal occlusion in these patients, as well as difficulties in establishing the correct diagnosis were encountered.Surgical cure of the occlusion, with palliative aim of course,was possible in only 47 cases (representing 77.05%). A standard treatment course cannot be devised for this type of patients. Palliative care, indispensable in cases of advanced neoplastic disease, remains the sole therapeutic method available for patients with no surgical cure for the obstruction. The main objective, for the entire study lot, was to ensure an as high as possible quality of life,a factor we must bear in mind as often as possible when choosing a surgical solution. Of course, when surgical treatment can be applied, overcoming the occlusive episode prolongs these patients' life and can even allow for other courses of complementary treatment to be undertaken.

To explore the significance of the tumour necrosis factor-α/interleukin-10 ratio and the effect of continuous positive airway pressure in patients with different degrees of obstructive sleep apnoea hypopnoea syndrome severity. This study comprised 135 patients with obstructive sleep apnoea hypopnoea syndrome and 94 control subjects. Tumour necrosis factor-α and tumour necrosis factor-α/interleukin-10 ratio values were significantly higher in the obstructive sleep apnoea hypopnoea syndrome group than in the control group, but interleukin-10 was significantly lower. Tumour necrosis factor-α/interleukin-10 ratio values increased in line with the severity of obstructive sleep apnoea hypopnoea syndrome. In multivariate analysis, the tumour necrosis factor-α/interleukin-10 ratio correlated positively with the apnoea-hypopnoea index and all indices of obstructive sleep apnoea hypopnoea syndrome, except for age, body mass index and neck circumference. After one month of continuous positive airway pressure therapy, levels of tumour necrosis factor-α decreased; interleukin-10 showed no change. The results suggest that inflammation is activated and anti-inflammatory cytokines are decreased in obstructive sleep apnoea hypopnoea syndrome patients. Tumour necrosis factor-α/interleukin-10 ratio may prove useful for severity monitoring and management of obstructive sleep apnoea hypopnoea syndrome patients, and may reduce the need for polysomnography.

Chronic obstructive parotitis related to Sjogren syndrome is not uncommon, but it is rarely reported in the literature. The aim of this study was to describe our experience in the treatment of chronic obstructive parotitis related to Sjogren syndrome. Seventeen cases of chronic obstructive parotitis related to Sjogren syndrome treated with sialendoscopy from June 2014 to June 2015 at the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medical University, were retrospectively reviewed. The cohort underwent ultrasonography, salivary gland scintigraphy, and sialography before sialendoscopy. All patients were asked to complete a visual analogue scale (VAS) evaluation before and 6 months after surgery. A paired t test was conducted, and P < .05 was considered statistically significant. The 17 study patients (27 parotid glands) successfully underwent interventional sialendoscopy under local anesthesia. The mean preoperative VAS score was 6, and the mean VAS score 6 months after sialendoscopy was significantly lower at 4.5 (P < .05). Interventional sialendoscopy plays a significant role in the treatment of chronic obstructive parotitis related to Sjogren syndrome. Copyright © 2016 Elsevier Inc. All rights reserved.

To provide an overview of the healthcare and societal consequences and costs of untreated obstructive sleep apnea syndrome. PubMed database for English-language studies with no start date restrictions and with an end date of September 2014. A comprehensive literature review was performed to identify all studies that discussed the physiologic, clinical and societal consequences of obstructive sleep apnea syndrome as well as the costs associated with these consequences. There were 106 studies that formed the basis of this analysis. Undiagnosed and untreated obstructive sleep apnea syndrome can lead to abnormal physiology that can have serious implications including increased cardiovascular disease, stroke, metabolic disease, excessive daytime sleepiness, work-place errors, traffic accidents and death. These consequences result in significant economic burden. Both, the health and societal consequences and their costs can be decreased with identification and treatment of sleep apnea. Treatment of obstructive sleep apnea syndrome, despite its consequences, is limited by lack of diagnosis, poor patient acceptance, lack of access to effective therapies, and lack of a variety of effective therapies. Newer modes of therapy that are effective, cost efficient and more accepted by patients need to be developed.

Intestinal obstructions/pseudo-obstruction of the small/large bowel are frequent conditions but their management could be challenging. Moreover, a general agreement in this field is currently lacking, thus SICUT Society designed a consensus study aimed to define their optimal workout. The Delphi methodology was used to reach consensus among 47 Italian surgical experts in two study rounds. Consensus was defined as an agreement of 75.0% or greater. Four main topic areas included nosology, diagnosis, management and treatment. A bowel obstruction was defined as an obstacle to the progression of intestinal contents and fluids generally beginning with a sudden onset. The panel identified four major criteria of diagnosis including absence of flatus, presence of >3.5 cm ileal levels or >6 cm colon dilatation and abdominal distension. Panel also recommended a surgical admission, a multidisciplinary approach, and a gastrografin swallow for patients presenting occlusions. Criteria for immediate surgery included: presence of strangulated hernia, a >10 cm cecal dilatation, signs of vascular pedicles obstructions and persistence of metabolic acidosis. Moreover, rules for non-operative management (to be conducted for maximum 72 hours) included a naso-gastric drainage placement and clinical and laboratory controls each 12 hours. Non-operative treatment should be suspended if any suspects of intra-abdominal complications, high level of lactates, leukocytosis (>18.000/mm3 or Neutrophils >85%) or a doubling of creatinine level comparing admission. Conversely, consensus was not reached regarding the exact timing of CT scan and the appropriateness of colonic stenting. This consensus is in line with current international strategies and guidelines, and it could be a useful tool in the safe basic daily management of these common and peculiar diseases.

To explore the value of employing the small intestinal feeding tube in treating high position intestinal obstruction of newborn infant. Five newborn infants (3 males and 2 females; 1 premature infant and 4 fully-mature infants; 2 had membranous atresia of duodenum, 1 had annular pancreas, and 2 had proximal small intestine atresia; 1 infant had malrotation). The duodenal membrane-like atresia and the blind-end of small intestine were removed and intestinal anastomosis was performed, which was combined with intestinal malrotation removal. Before the intestinal anastomosis surgery, the anesthetist inserted via nose a 6Fr small intestinal ED tube, made by CREATE MEDIC CO LTD of Japan[ the State Food and Drug Administration-instrument (Im.) 2007-NO.2661620]. Twenty-four hours after surgery, abdominal X-ray plain film was taken and patients were fed with syrup; 48 hours later, formula milk was pumped or lactose-free milk amino acids were given by intravenous injection pump through the feeding tube. The amount of milk and fluids was gradually increased to normal amount according to the condition. In initial 3 days the intravenous nutrition was given and one week after operation, the infants were fed through mouth in addition to pumping milk through the tube and stopped infusion. Ten to 22 days after operation, the tube was removed and the infant patients were discharged. All the five infants showed that the feeding through the nutrition tube was accomplished and the time of venous nutrition was reduced and fistula operation was avoided. None of the infants on question was off the tube and no jaundice exacerbation was found and the liver function was also found normal. At the very beginning, the tube was occasionally blocked by milk vale in one infant and after 0.9% sodium chloride solution flushing patency restored. After that, the feeding tube was washed once with warm water after feeding. In one infant vomiting occurred due to enough oral milk. The photograph of upper

To investigate the long-term follow-up of distal intestinal obstruction syndrome (DIOS) in Israeli cystic fibrosis (CF) patients. This is a multi-center, comparative, retrospective study in which we reviewed the medical records of all CF patients from three major CF centers in Israel who were treated in the period from 1980 to 2012. Patients diagnosed with DIOS were defined as the study group. The patients were diagnosed with DIOS based on their clinical presentation and typical findings on either abdominal X-ray or computerized tomography scan. For the control group, CF patients with no DIOS were matched to the patients in the study group for age, sex, and cystic fibrosis transmembrane conductance regulator (CFTR) mutations. For both groups, the collected data included age, sex, CFTR genotype, weight, height, and body mass index. Clinical data included respiratory function tests in the last five years prior to the study, respiratory function test immediately before and after the DIOS event, number of hospitalizations, sputum culture results, and CF-related conditions diagnosed according to the CF clinical practice guidelines. In the study group, data on the DIOS treatment and tendency for DIOS recurrence were also analyzed. The medical charts for a total of 350 CF patients were reviewed. Of the 350 CF patients, 26 (7.4%) were diagnosed with DIOS. The control group included 31 CF patients with no DIOS diagnosis. The mean follow-up period was 21.6 ± 8.2 years. The total of DIOS episodes in the follow-up period was 60. The distribution of DIOS episodes was as follows: 6/26 (23.1%) study patients had one episode of DIOS in their lifetime, 7/26 (26.9%) had two episodes, 7/26 (26.9%) had three episodes, and 6/26 (23.1%) had four or more episodes. Compared to the control group, DIOS patients had a significantly higher incidence of meconium ileus in the past (65.4% vs 0%, respectively, P < 0.02), more Aspergillus spp. colonization (34.6% vs 3.2%, respectively, P < 0

Goltz-Gorlin syndrome is a rare autosomal dominant hereditary disease associated with a high rate of spontaneous mutation. Diagnosis is based on clinically defined major and minor criteria. The disease is caused by a gene mutation locating to chromosome 9q22-31. We report on a young Goltz-Gorlin syndrome patient with obstructive sleep apnea syndrome. Due to intolerance to continuous positive airway pressure (CPAP) therapy and in order to avoid a tracheotomy, we opted for an alternative therapy comprising interdisciplinary multi-level surgery.

Introduction. Vitelline artery remnants are rare causes of intra-abdominal bands leading to bowel obstruction. These bands may be associated with Meckel's diverticulum. Double inferior vena cava (IVC) is a rare presentation and is usually identified incidentally. Case Presentation. A sixty-year-old male presented with progressive vomiting for five days and he was clinically diagnosed with intestinal obstruction. Plain X-ray abdomen showed evidence of small bowel obstruction. CT scan of the abdomen revealed dilated small bowel loops with a small outpouching in the distal ileum with a band like structure attached to it. In the CT, left sided patent IVC draining into the left renal vein was identified. Left external iliac vein was in continuity with the left IVC. Left internal iliac vein was draining into the right IVC. Exploratory laparotomy revealed a Meckel's diverticulum with a band identified as the vitelline remnant attached to its apex and inserting at the anterior abdominal wall near the umbilicus. Discussion. Meckel's diverticulum with vitelline bands, although rare, should be borne in mind in adult patients with intestinal obstruction. Identification of this anomaly can be difficult in imaging studies. Presence of double IVC should be mentioned in the imaging findings to prevent possible catastrophic complications during surgery.

Gallstone ileus is an uncommon cause of small bowel obstruction. When the gallstone lodges inside the duodenum and causes gastric outlet obstruction, it is termed Bouveret's syndrome. However, it is rather unusual to seen the evolution of a migrating gallstone (from duodenum to distal small bowel) in a patient during the same hospital admission. We report a case of gallstone ileus from the initial presentation of gastric outlet obstruction to the development of distal small bowel obstruction within the same hospital admission, and its total laparoscopic treatment.

Phaeochromocytomas are rare neuroendocrine tumours with variable clinical signs and symptoms. Hypertension, tachycardia, sweating and headaches are cardinal manifestations. Although nausea and abdominal pain are the more common gastrointestinal features, rare gastrointestinal spectrums have been reported that can mimic abdominal emergencies. Metabolic effects of hypercatecholaminaemia are vast and one such rare presentation is lactic acidosis. We describe a case of phaeochromocytoma presenting with both intestinal pseudo-obstruction as well as lactic acidosis. This case report highlights the importance of having a high index of suspicion for and early recognition of the gastrointestinal and metabolic manifestations of phaeochromocytomas.

We analyzed site, pattern and degree of obstruction in Korean male obstructive sleep apnea syndrome (OSAS) patients by drug-induced sleep endoscopy (DISE). We also investigated possible links between BMI, AHI and DISE findings. Sixty-nine male patients underwent DISE. DISE findings were reported using our classification system in which modified 'VOTE classification' - obstruction type, site of obstruction, degree of obstruction and anatomical site contributing obstruction - was reported. Associations were analyzed among the results of the polysomnography, patients' characteristics and DISE finding. Multilevel airway obstruction was found in 84.06% of patients and 15.94% had a unilevel obstruction. Among those with unilevel obstruction, 90.90% had retropalatal level obstruction and 9.10% had retrolingual level obstruction. Palate with lateral pharyngeal wall obstruction (49.28%) is the most common obstruction type of the retropalatal level and tongue with lateral pharyngeal wall (37.68%) is the most common obstruction type of the retrolingual level. Examining the relation between obstruction site according to body mass index (BMI) and severity of OSAS (apnea hypopnea index, AHI), the lateral pharyngeal wall had an increasing tendency associated with higher BMI and higher AHI. But the lateral pharyngeal wall of both levels was statistically significant associated with higher AHI. The majority of the Korean male OSAS patients have multilevel obstruction and according to BMI and AHI, the DISE findings indicate that the lateral pharyngeal wall is the most important anatomical site contributing to obstruction regardless of the level at which the obstruction lies. © 2013 Elsevier Inc.

Children with syndromic craniosynostosis often have obstructive sleep apnea and intracranial hypertension. The authors aimed to evaluate (1) sleep architecture, and determine whether this is influenced by the presence of obstructive sleep apnea and/or intracranial hypertension; and (2) the effect of treatment on sleep architecture. This study included patients with syndromic craniosynostosis treated at a national referral center, undergoing screening for obstructive sleep apnea and intracranial hypertension. Obstructive sleep apnea was identified by polysomnography, and categorized into no, mild, moderate, or severe. Intracranial hypertension was identified by the presence of papilledema on funduscopy, supplemented by optical coherence tomography and/or intracranial pressure monitoring. Regarding sleep architecture, sleep was divided into rapid eye movement or non-rapid eye movement sleep; respiratory effort-related arousals and sleep efficiency were scored. The authors included 39 patients (median age, 5.9 years): 19 with neither obstructive sleep apnea nor intracranial hypertension, 11 with obstructive sleep apnea (four moderate/severe), six with intracranial hypertension, and three with obstructive sleep apnea and intracranial hypertension. Patients with syndromic craniosynostosis, independent of the presence of mild obstructive sleep apnea and/or intracranial hypertension, have normal sleep architecture compared with age-matched controls. Patients with moderate/severe obstructive sleep apnea have a higher respiratory effort-related arousal index (p < 0.01), lower sleep efficiency (p = 0.01), and less rapid eye movement sleep (p = 0.04). An improvement in sleep architecture was observed following monobloc surgery (n = 5; rapid eye movement sleep, 5.3 percent; p = 0.04). Children with syndromic craniosynostosis have in principle normal sleep architecture. However, moderate/severe obstructive sleep apnea does lead to disturbed sleep architecture, which fits within

A young adult black female, known to be a prostitute and suspected of smuggling narcotics, was found dead in her apartment in a state of early decomposition. Oval-shaped gray-white masses of exogenous origin protruded from the anus. The autopsy showed dilatation of the folds of the large intestine, which were almost completely filled with these oval-shaped gray-white masses of foreign material. The uterus was enlarged with multiple large leiomyomas. Toxicological tests of blood and the foreign material revealed no toxicologically relevant substances. Kaolin was detected in a sample of the foreign material from the large intestine. The immediate cause of death was intestinal obstruction due to the formation of a kaolin bezoar with simultaneous compression of the large intestine by the enlarged myomatous uterus. Subsequent revelation of a habit the deceased had brought from her native country led to the conclusion that this exotic custom was responsible for her death. © 2018 American Academy of Forensic Sciences.

To evaluate the effect of continuous positive airway pressure (CPAP) therapy on pro-brain natriuretic peptide (BNP) and cardiac markers in patients with obstructive sleep apnea syndrome and normal cardiac function. Thirty-three consecutive patients with sleep apnea syndrome were analysed for serum pro-BNP and cardiac markers prior to and after 6 months of CPAP therapy. Twenty five patients had normal (83.3%) while remaining five (16.7%) revealed high pro-BNP values. We did not detect any significant difference between severity of obstructive sleep apnea syndrome and serum pro-BNP levels (p = 0.534). A statistically significant difference was not observed between basal and sixth-month creatine kinase (CK), creatine kinase-MB (CK-MB), troponin I, pro-BNP, aspartate transaminase (AST), and CK levels in patients with sleep apnea syndrome (p > 0.05). Obstructive sleep apnea syndrome does not induce myocardial damage enough to increase serum pro-BNP, CK, CK-MB, troponin I, and AST levels. Markers sensitive to ischemia could be preferred to evaluate effect of obstructive sleep apnea syndrome.

This study was performed to evaluate the diagnostic performance of multi-slice CT angiography combined with enterography in determining the cause and location of obstruction as well as intestinal ischaemia in patients with small bowel obstruction (SBO). This study retrospectively summarized the image data of 57 SBO patients who received both multi-slice CT angiography and enterography examination between December 2012 and May 2013. The CT diagnoses of SBO and intestinal ischaemia were correlated with the findings at surgery or digital subtraction angiography, which were set as standard references. Multi-slice CT angiography and enterography indicated that the cause of SBO in three patients was misjudged, suggesting a diagnostic accuracy of 94.7%. In one patient the level of obstruction was incorrect, demonstrating a diagnostic accuracy of 98.2%. Based on the results of the receiver operating characteristic (ROC) curve analysis, the diagnostic criterion for ischaemic SBO was at least two of the four CT signs (circumferential bowel wall thickening, reduced enhancement of the intestinal wall, mesenteric oedema and mesenteric vascular engorgement). The criterion yielded a sensitivity of 94.4%, a specificity of 92.3%, a positive predicted value of 85.0% and a negative predicted value of 97.3%, and the area under curve (AUC) was 0.92 (95% CI, 0.85-0.99). Multi-slice CT angiography and enterography have high diagnostic value in identifying the cause and site of SBO. In addition, the suggested diagnostic criterion using CT signs is helpful for diagnosing intestinal ischaemia in SBO patients. © 2016 The Royal Australian and New Zealand College of Radiologists.

Obstructive sleep apnea syndrome and laryngopharyngeal reflux are diseases with a high prevalence in the overall population; however, it remains unclear whether they are diseases with the same risk factors present in the same populations or if there is any association between them. To evaluate and determine the prevalence of laryngopharyngeal reflux in patients with moderate and severe obstructive apnea syndrome and also to determine its predictive factors. Historical cohort, cross-sectional study of patients aged 18-70 years, referred to a tertiary service Otorhinolaryngology outpatient clinic with a polysomnographic diagnosis of moderate or severe obstructive sleep apnea syndrome. The reflux symptom index questionnaire and the reflux finding score at indirect videolaryngoscopy were applied to the assessed population, considering the inclusion and exclusion criteria. Fifty-six patients were evaluated, of which 64.3% had a positive laryngopharyngeal reflux (positive reflux symptom index and/or positive endolaryngeal reflux finding score). Body mass index was a predictor of reflux presence in this group of patients with moderate to severe obstructive sleep apnea syndrome. In patients with positive score for endoscopic findings and reflux symptom index (12.3%), there was a trend toward significance for a higher mean apnea-hypopnea index and a higher percentage of sleep time with oxyhemoglobin saturation below 90% (p=0.05). The prevalence of laryngopharyngeal reflux was higher in this group of patients with moderate to severe obstructive sleep apnea syndrome, and the body mass index was a predictor of laryngopharyngeal reflux in these patients. There was a trend toward greater oxyhemoglobin desaturation in patients with a positive score for reflux symptoms index (RSI) and reflux finding score (RFS).

Our aim was to collect a large number of cases to characterize clinical presentation, outcome, and prognosis of chronic intestinal pseusoobstruction in children. We conducted a retrospective multicenter study that included children treated for chronic intestinal pseusoobstruction defined as recurrent episodes of intestinal obstruction with no mechanical obstruction, excluding Hirschsprung's disease. In all, 105 children, 57 boys and 48 girls, were studied, including five familial forms. Prenatal diagnosis was made in 18 patients. Eighty patients were less than 12 months old at onset; the disease began at birth for 37 patients. The most frequent signs were abdominal distension, vomiting, and constipation. Megacystis was noted in myopathies (7 cases), neuropathies (10 cases) and unclassified forms (13 cases). For all but three cases (two patients with CMV infection, one with Munchhausen-by-proxy syndrome), the associated diseases and disorders could not account for chronic intestinal pseusoobstruction as a secondary disorder. At least one full-thickness biopsy from the digestive tract was studied for 99 patients. The diagnosis recorded was visceral neuropathy in 58 cases, visceral myopathy in 17 cases, and uncertain or normal biopsy results in 24 cases. Seventy-eight children were fed intravenously, and only 18 were able to be fed orally throughout their illness. Seventy-one patients underwent surgery during their illness, and 217 surgical procedures, a mean of 3 per patient, were performed. Ostomy was the most performed procedure. Follow-up continued in 89 patients for 3 months to 16 years (mean 85 months). Forty-two patients were still fed by parenteral (39 patients) or enteral nutrition (3 patients) at the time of the study. Eleven patients died between the age of 1 month and 14 years 7 months.

Intestinal Failure: New Definition and Clinical Implications.

Intestinal failure (IF) is a state in which the nutritional demands of the body are not met by the gastrointestinal absorptive surface. It is a long-recognized complication associated with short bowel syndrome, which results in malabsorption after significant resection of the intestine for many reasons or functional dysmotility. Etiologies have included Crohn's disease, vascular complications, and the effects of radiation enteritis, as well as the effects of intestinal obstruction, dysmotility, or congenital defects. While IF has been long-recognized, it has historically not been uniformly defined, which has made both recognition and management challenging. This review examines the previous definitions of IF as well as the newer definition and classification of IF and how it is essential to IF clinical guidelines.

The present study investigated the effect of Daikenchuto (DKT) on postoperative intestinal adhesion in rats. We evaluated the effects of DKT, constituent medical herbs and active compounds on talc-induced intestinal adhesion in rats and DKT-induced contractions using isolated guinea pig ileum. DKT significantly prevented adhesion formation, and this action was inhibited by pretreatment with atropine or ruthenium red. The constituent medical herbs, Zanthoxylum Fruit and Maltose Syrup Powder significantly prevented adhesion formation. Moreover, hydroxy sanshool (HS) prevented adhesion formation, and this action was inhibited by pretreatment with ruthenium red. In contrast, DKT-induced contractions were inhibited by tetrodotoxin, atropine, and capsazepine. These results suggested that DKT had a preventive action on postoperative adhesive intestinal obstruction, and that this action was mediated by sensory and cholinergic nerves. Furthermore, HS was found to be one of the active compound of DKT, and its action was mediated by sensory nerves.

Obstructive sleep apnoea syndrome (OSAS), characterised by intermittent hypoxia/re-oxygenation, has been identified as an independent risk factor for cardiovascular diseases and endothelial dysfunction. Our aim was to investigate flow-mediated dilatation (FMD) in patients with obstructive sleep apnoea with and without metabolic syndrome. Fifty-two subjects with OSAS diagnosed by polysomnography were classified into 2 groups according to the presence and absence of the metabolic syndrome and also according to the severity: mild to moderate OSAS group and severe OSAS group. Endothelial function of the brachial artery was evaluated by using high-resolution vascular ultrasound. Endothelial-dependent dilatation (EDD) was assessed by establishing reactive hyperaemia and endothelial-independent dilatation (EID) was determined by using sublingual isosorbide dinitrate. Spearman correlation and regression analysis were performed. EDD was not significantly different in patients with OSAS and metabolic syndrome as compared with OSAS without metabolic syndrome (4.62 +/- 0.69 versus 4.49 +/- 0.93, P >0.05). Endothelial dysfunction in OSA may be independent of metabolic syndrome.

Several studies have investigated the prevalence and risk factors of insomnia in subjects with obstructive sleep apnea syndrome. However, few studies have investigated the prevalence and risk factors for obstructive sleep apnea syndrome in insomnia sufferers. Thus, the aim of this study was to examine the prevalence and risk factors of moderate to severe obstructive sleep apnea syndrome in a large sample of insomnia sufferers. Data from 1311 insomnia sufferers who were recruited from the research database of the sleep laboratory of the Erasme Hospital were analysed. An apnea-hypopnea index of ≥15 events per hour was used as the cut-off score for moderate to severe obstructive sleep apnea syndrome. Logistic regression analyses were conducted to examine clinical and demographic risk factors of moderate to severe obstructive sleep apnea syndrome in insomnia sufferers. The prevalence of moderate to severe obstructive sleep apnea syndrome in our sample of insomnia sufferers was 13.88%. Multivariate logistic regression analysis revealed that male gender, snoring, excessive daytime sleepiness, lower maintenance insomnia complaint, presence of metabolic syndrome, age ≥ 50 & <65 years, age ≥ 65 years, BMI ≥ 25 & <30 kg/m 2 , BMI >30 kg/m 2 , and CRP >7 mg/L were significant risk factors of moderate to severe obstructive sleep apnea syndrome in insomnia sufferers. Moderate to severe obstructive sleep apnea syndrome is a common pathology in insomnia sufferers. The identification of these different risk factors advances a new perspective for more effective screening of moderate to severe obstructive sleep apnea syndrome in insomnia sufferers.

[Obstructive sleep apnea-hypopnea syndrome in children: beyond adenotonsillar hypertrophy].

Esteller, Eduard

2015-01-01

The prevalence of obstructive sleep apnea-hypopnea syndrome in the general childhood population is 1-2% and the most common cause is adenotonsillar hypertrophy. However, beyond adenotonsillar hypertrophy, there are other highly prevalent causes of this syndrome in children. The causes are often multifactorial and include muscular hypotonia, dentofacial abnormalities, soft tissue hypertrophy of the airway, and neurological disorders). Collaboration between different specialties involved in the care of these children is essential, given the wide variability of conditions and how frequently different factors are involved in their genesis, as well as the different treatments to be applied. We carried out a wide literature review of other causes of obstructive sleep apnea-hypopnea syndrome in children, beyond adenotonsillar hypertrophy. We organised the prevalence of this syndrome in each pathology and the reasons that cause it, as well as their interactions and management, in a consistent manner.

Fructokinase, Fructans, Intestinal Permeability, and Metabolic Syndrome: An Equine Connection?

Fructose is a simple sugar present in honey and fruit, but can also exist as a polymer (fructans) in pasture grasses. Mammals are unable to metabolize fructans, but certain gram positive bacteria contain fructanases and can convert fructans to fructose in the gut. Recent studies suggest that fructose generated from bacteria, or directly obtained from the diet, can induce both increased intestinal permeability and features of metabolic syndrome, especially the development of insulin resistance. The development of insulin resistance is driven in part by the metabolism of fructose by fructokinase C in the liver, which results in oxidative stress in the hepatocyte. Similarly, the metabolism of fructose in the small bowel by intestinal fructokinase may lead to increased intestinal permeability and endotoxemia. While speculative, these observations raise the possibility that the mechanism by which fructans induce laminitis could involve intestinal and hepatic fructokinase. Further studies are indicated to determine the role of fructanases, fructose and fructokinase in equine metabolic syndrome and laminitis. PMID:23439477

Sickle cell disease is a chronic hematologic disease with variable but often severe systemic symptoms. In this report, we describe a 6-year-old boy presenting with acute bowel pseudo-obstruction. During this episode, previously undiagnosed sickle cell disease was discovered upon peripheral blood smear analysis. The condition was therefore interpreted as a massive intestinal vaso-occlusive crisis or "girdle syndrome". Conservative treatment with hydration therapy, analgesia and a manual partial exchange transfusion was initiated. The patient fully recovered within 5 days. Girdle syndrome is a rare but severe adverse event associated with sickle cell disease that must be considered as differential diagnosis in patients with sickle cell disease. © Georg Thieme Verlag KG Stuttgart · New York.

The persistence of the onphalomesenteric duct has been reported in several pediatric publications either through the appearance of Meckel diverticulum that are commonest, or by the appearance of segments with partial or total permeability of itself. Sporadic cases have appeared where this anomaly has originated episodes of intestinal obstruction in infants and children specially under the form of a fibrous band. However, adult presentations extremely infrequent. The case presented in this report shows compatible findings with a onphalomesenteric conduit with partial permeability, that I originate an intestinal picture of obstruction in a young adult.

Bowel obstruction in patients with Alpers-Huttenlocher syndrome.

Spiegler, J; Stefanova, I; Hellenbroich, Y; Sperner, J

Alpers-Huttenlocher syndrome (AHS) is a very rare autosomal recessive disorder. AHS is caused by homozygous or compound heterozygous mutations in the nuclear gene encoding mitochondrial DNA polymerase gamma (POLG, chromosome 15q25). Most patients become symptomatic before the age of 2 years. We report 3 patients who were treated in our clinic between 2007 and 2010. All patients suffered from myoclonic seizures and had at least one refractory convulsive status which led to the diagnosis. All of them had varying degrees of developmental delay, 2 of them additionally ataxia. Gastrointestinal motility problems were severe in all patients despite only mildly deranged liver function. While in most aspects our patients present with typical AHS features, they also share intestinal problems, a feature that has not been recognized as typical for AHS before. AHS is a multisystem disorder that does affect all cell systems. Liver and brain are organs with the highest energy demand and are therefore usually affected early in the disease course of AHS. However, constipation and bowel obstruction should be regarded as typical complications in AHS and patients should be monitored and treated to improve quality of life. Regarding treatment options for epilepsy in AHS ketogenic diet as well as lacosamide might be considered. © Georg Thieme Verlag KG Stuttgart · New York.

Neonatal ovarian torsion complicated by intestinal obstruction and perforation, and review of the literature.

We present a case of neonatal ovarian torsion complicated by bowel obstruction and perforation and review the literature regarding the incidence of bowel obstruction in neonatal ovarian cysts, the presentation, and treatment. A term neonate was prenatally diagnosed with a cystic abdominal mass palpable on physical examination. A postnatal abdominal x-ray showed paucity of gas in the left hemiabdomen with rightward displacement of bowel loops. Exploratory laparotomy on day 2 of life revealed a large cystic mass in the left lower quadrant consistent with a torsed left ovary, an omental band causing strangulation of the bowel mesentery, and a perforation of the distal ileum. Our literature search revealed 19 reported cases of neonatal ovarian cysts resulting in bowel obstruction. Infants may present with a palpable abdominal mass, respiratory distress, as well as signs and symptoms of intestinal obstruction. Two mechanisms exist for bowel obstruction: adhesions caused by a torsed necrotic ovary and mass effect of a large ovarian cyst, often measuring 9 to 10 cm in diameter. Options to treat ovarian cysts include antenatal or postnatal aspiration, laparoscopy, and laparotomy. Cysts less than 4 to 5 cm can be observed, whereas operative intervention is indicated in symptomatic cases and in persistent or enlarging ovarian cysts. Copyright 2010 Elsevier Inc.

Intestinal volvulus is a life-threatening emergency requiring prompt surgical management. Prenatal intestinal volvulus is rare, and most are secondary to intestinal atresia, mesenteric defect or without any underlying cause. Cystic fibrosis (CF) is known to cause digestive tract disorders. After birth, 10-15% of newborns with CF may develop intestinal obstruction within a few days of birth because of meconial ileus. 1 This obstruction is a result of dehydrated thickened meconium obstructing the intestinal lumen. We report two cases of fetuses with prenatal diagnosis of segmental volvulus in whom CF was diagnosed. 2016 BMJ Publishing Group Ltd.

Sinusoidal obstruction syndrome.

2016-09-01

Sinusoidal obstruction syndrome (SOS) is characterized by damage to small hepatic vessels affecting particularly sinusoidal endothelium. Damaged sinusoids can be associated with a partial or complete occlusion of small hepatic veins, hence the previous denomination of hepatic veno-occlusive disease (VOD). Exposure to certain exogenous toxins appears to be specific to this condition and is frequently included in its definition. Typical histopathological features of SOS in a liver biopsy specimen are presented in the text. The purpose of this article is to provide an overview on the different entities corresponding to this general definition. Such entities include: (i) liver disease related to pyrrolizidine alcaloids; (ii) liver injury related to conditioning for hematopoietic stem cell transplantation; (iii) vascular liver disease occurring in patients treated with chemotherapy for liver metastasis of colorectal cancer; and (iv) other liver diseases related to toxic agents.

To evaluate airway obstruction due to abnormal intranasal anatomy in 3 brachycephalic dog breeds using computed tomography and rhinoscopy. Prospective clinical study. A total of 132 brachycephalic dogs (66 Pugs, 55 French Bulldogs, and 11 English Bulldogs) with severe respiratory distress due to brachycephalic syndrome. Computed tomography and anterior and posterior rhinoscopy were performed to evaluate endonasal obstruction. All dogs had abnormal conchal growth that obstructed the intranasal airways. Rostral aberrant turbinates (RAT) were common in Pugs (90.9%) but less frequent in French (56.4%) and English (36.4%) Bulldogs. Caudal aberrant turbinates (CAT) obstructing the nasopharyngeal meatus were commonly found in all breeds (66.7%). Deviation of the nasal septum was an almost consistent finding in Pugs (98.5%) but was less common in bulldogs. Obstructing turbinates had multiple points of mucosal contact responsible for obstruction of the intranasal airway. Interconchal and intraconchal mucosal contacts were evident in 91.7% of dogs. Selective breeding for short head conformation reduces the size of the nasal cavities to such an extent that intranasal structures grow aberrantly and malformed, leading to obstructed air conducting spaces. Intranasal airway obstruction of brachycephalic dogs may contribute to their exercise and heat intolerance because of impaired pulmonary ventilation and compromised thermoregulatory functions of the canine nose. Failure to address intranasal obstruction might be an explanation for lack of therapeutic success after conventional surgery for brachycephalic syndrome. Future consideration should be given to the diagnosis, management, and treatment of this newly described aspect of airway obstruction. © Copyright 2016 by The American College of Veterinary Surgeons.

Percutaneous endoscopic colostomy (PEC) is increasingly proposed as an alternative to surgery to treat various disorders, including acute colonic pseudo-obstruction, chronic intestinal pseudo-obstruction and relapsing sigmoid volvulus. We report on a severe complication that occurred two months after PEC placement. A 74-year-old man with a history of chronic intestinal pseudo-obstruction evolving since 8 years was readmitted to our hospital and received PEC to provide long-standing relief. The procedure was uneventful and greatly improved the patient’s quality of life. Two months later, the patient developed acute stercoral peritonitis. At laparotomy, the colostomy flange was embedded in the abdominal wall but no pressure necrosis was found at the level of the colonic wall. This complication was likely related to inadvertent traction of the colostomy tube. Subtotal colectomy with terminal ileostomy was performed. We review the major features of 60 cases of PEC reported to date, including indications and complications. PMID:17465514

OBJECTIVE: Obstructive sleep apnea syndrome is associated with cardiovascular diseases and thromboembolic events. The mean platelet volume (MPV) is a predictor of cardiovascular thromboembolic events. The aim of the present study is to investigate the association between the MPV and disease severity in patients with obstructive sleep apnea syndrome. METHODS: We prospectively included 194 obstructive sleep apnea syndrome patients without cardiovascular disease (mean age 56.5±12.5 years) who were undergoing sleep tests. An overnight full laboratory polisomnography examination was conducted on each patient. The patients were divided into 3 groups according to the apnea-hypopnea index (AHI): (1) AHIlow group: 5≤AHI<15, (2) AHImid group: 1530. RESULTS: The highest MPV values were found in the AHIhigh group compared with other groups (p<0.05 for all). Multiple linear regression analysis indicated that the MPV was associated with the AHI (β=0.500, p<0.001) and the high sensitivity C-reactive protein (hs-CRP) level (β=0.194, p=0.010). CONCLUSION: The MPV is independently associated with both disease severity and inflammation in patients with obstructive sleep apnea syndrome. PMID:26222817

To describe the pattern of upper airway (UA) obstruction during drug-induced sedation endoscopy (DISE) and to evaluate the outcome of DISE-directed treatment. Prospective study of DISE in surgically naive obstructive sleep apnea syndrome (OSAS) children without syndromic comorbidity or craniofacial abnormalities. Treatment was individually tailored according to UA findings during DISE and polysomnographic data. Reported values are median (lower-upper quartile). Thirty-seven children aged 4.1 years (2.1-6.0), with body mass index z-score 0.3 (-0.9 to 0.9), and obstructive apnea-hypopnea index (oAHI) 9.0/h (6.1-19.3) were included. Adenotonsillar obstruction was found in 33 cases (89%) as an isolated entity or as part of a multi-level obstruction. These children were treated with adenotonsillectomy (n = 28), adenoidectomy (n = 3), or tonsillectomy (n = 2). The remaining four patients received non-surgical treatment. Pre-postoperative polysomnographic data in 22 patients showed a significant improvement in oAHI from 8.6/h (6.7-20.7) to 1.0/h (0.6-2.0) (P = 0.001). Only two of these 22 children had residual OSAS (oAHI ≥ 5/h), indicating a success rate of 91%. Based on UA findings during DISE, a non-surgical treatment was proposed for 11% of children. A 91% success rate was obtained in those treated with (adeno)tonsillectomy. These data suggest that DISE may be helpful to identify patients most likely to benefit from UA surgery.

The aim of this study was to examine the relationships between gluteal adipose tissue fatty acids and sleep quality in obese patients with obstructive sleep apnoea syndrome after controlling for possible confounders. Sixty-three patients with obstructive sleep apnoea syndrome based on overnight attended polysomnography were included. Gluteal adipose tissue fatty acids were analysed by gas chromatography. Anthropometric measurements were carried out. Depressive symptoms were assessed by the Zung Self-rating Depression Scale. Saturated fatty acids were positively related to total sleep time, sleep efficiency and rapid eye movement sleep. Significant positive associations were found between polyunsaturated fatty acids and sleep efficiency and rapid eye movement sleep. Moreover, n-3 fatty acids were positively associated with sleep efficiency, slow wave sleep and rapid eye movement sleep. This study revealed independent associations between certain gluteal adipose tissue fatty acids and sleep quality after controlling for age, gender, obesity, obstructive sleep apnoea syndrome indices and Zung Self-rating Depression Scale scores in patients with moderate to severe obstructive sleep apnoea syndrome. © 2013 European Sleep Research Society.

2008-07-01

Intranasal corticosteroids have been advanced as a nonsurgical therapeutic alternative for pediatric obstructive sleep apnea syndrome, particularly for patients with mild disease, and aims at reducing the size of hypertrophic adenotonsillar tissue. Of 71 possible candidates, 62 children with polysomnographically diagnosed mild obstructive sleep apnea syndrome were recruited onto a double-blind, randomized, crossover trial of intranasal budesonide (32 microg per nostril at bedtime) or placebo for 6 weeks followed by an additional 6-week treatment in the alternative treatment arm after allowing for a 2-week washout period. Polysomnographic assessment and radiographs for assessment of adenoid size were performed after completion of each phase. There were significant improvements in both polysomnographic measures (sleep latency, slow-wave sleep, and rapid-eye-movement sleep), in the magnitude of respiratory disturbance (apnea/hypopnea index, nadir pulse oxygen saturation), and in adenoid size among the 48 children who completed the treatment phase compared with 32 children who received placebo in their initial arm, with normalization of sleep measures in 54.1% of the treated children. Furthermore, discontinuation of treatment for 8 weeks for 25 children revealed a sustained duration of the initial treatment effect. A 6-week treatment with intranasal budesonide effectively reduced the severity of mild obstructive sleep apnea syndrome and the magnitude of the underlying adenoidal hypertrophy, and this effect persisted for at least 8 weeks after cessation of therapy. These findings justify the use of topical steroids as the initial therapeutic option in otherwise healthy children with mild obstructive sleep apnea.

We present a case of extensive gastric heterotopia involving the small intestine associated with congenital short bowel syndrome and malrotation. The infant showed a normal mesenteric artery, without signs of "apple peel" deformity. Gastric heterotopia extended from the duodenum to the mid-ileum involving the short bowel. Gastric mucosa heterotopia may involve any segment of the gastrointestinal tract. It can be associated with pancreatic heterotopia and Meckel diverticulum. However, our case showed involvement of two-thirds of the small intestine without pancreatic heterotopia. To our knowledge, this is the first report of gastric heterotopia with congenital short gut syndrome and malrotation.

Two birds from a zoological collection suffered fatal intestinal obstruction after each ingested single particles of polyacrylamide gel. Polyacrylamide gel, used in soils for gardening and agriculture, exists as small granules in the dehydrated state but expands markedly upon exposure to water. Polyacrylamide gel might, therefore, be an unrecognized hazard for captive and wild birds and other small animals if consumed.

Snoring sounds generated by different vibrators of the upper airway may be useful indicators of obstruction sites in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). This study aimed to investigate associations between snoring sounds, obstruction sites, and surgical responses (≥50% reduction in the apnea-hypopnea index [AHI] and <10 events/hour) in patients with OSAHS. This prospective cohort study recruited 36 OSAHS patients for 6-hour snoring sound recordings during in-lab full-night polysomnography, drug-induced sleep endoscopy (DISE), and relocation pharyngoplasty. All patients received follow-up polysomnography after 6 months. Fifteen (42%) patients with at least two complete obstruction sites defined by DISE were significantly, positively associated with maximal snoring sound intensity (40–300 Hz; odds ratio [OR], 1.25, 95% confidence interval [CI] 1.05–1.49) and body mass index (OR, 1.48, 95% CI 1.02–2.15) after logistic regression analysis. Tonsil obstruction was significantly, inversely correlated with mean snoring sound intensity (301–850 Hz; OR, 0.84, 95% CI 0.74–0.96). Moreover, baseline tonsil obstruction detected by either DISE or mean snoring sound intensity (301–850 Hz), and AHI could significantly predict the surgical response. Our findings suggest that snoring sound detection may be helpful in determining obstruction sites and predict surgical responses. PMID:27471038

Obstructive sleep apnea syndrome obstructive sleep apnea syndrome is associated with symptoms including habitual snoring, witness apnea and excessive daytime sleepiness. Also obstructive sleep apnea syndrome is related to some occupations which are needed attention for work accident. We aimed to determine the prevalence of snoring, witnessed apnea and excessive daytime sleepiness in coal workers and healthy adults in Zonguldak city center, and also evaluate the differences between these groups. This study consisted of 423 underground coal workers and 355 individuals living in centre of Zonguldak. Study and comparison group were chosen by nonstratified randomized sampling method. Data were collected by a questionnaire that included information regarding snoring, witnessed apnea and excessive daytime sleepiness. Mean age was 43.3 ± 6.05 years in miners and 44.3 ± 11.8 years in comparison group. In miners, snoring frequency was determined as 42.6%, witnessed apneas were 4.0%, and daytime sleepiness were 4.7%. In comparison group, these symptoms were 38.6%, 4.8% and 2.8% respectively. There were no statistical differences between coal workers and comparison group in these symptoms. Also snoring prevalence was higher in smoker miners. We found that major symptoms of obstructive sleep apnea syndrome in coal workers are similar to general population in Zonguldak. Further studies that constucted higher populations and with polysomnography are needed to evaluate these findings.

An 85-year-old woman with no history of abdominal surgery complained of abdominal pain and vomiting and was referred to us with a diagnosis of intestinal obstruction a few days later. Upon admission to our facility, she presented with marked abdominal swelling and prominent kyphosis. Because of the kyphosis, most of the dilated bowel was compressing her thoracic cavity. No obvious strangulation or free air was observed via abdominal computed tomography imaging. We attempted decompression using a nasogastric tube, but the symptoms persisted. Surgery was performed 2 days after admission. The origin of the obstruction was a compression of the ileocecal region by the costal arch. The bowel was discolored, and thus surgically excised. There were no major postsurgical complications other than a mild wound infection. Until now, there have been no reports of advanced kyphosis inducing ileus, but there are concerns of an increase in similar cases as society continues to age. PMID:23971780

Numerous studies have reported an association between nasal obstruction and obstructive sleep apnea syndrome (OSAS), but the precise nature of this relationship remains to be clarified. This paper aimed to summarize data and theories on the role of the nose in the pathophysiology of sleep apnea as well as to discuss the benefits of surgical and medical nasal treatments. A number of pathophysiological mechanisms can potentially explain the role of nasal pathology in OSAS. These include the Starling resistor model, the unstable oral airway, the nasal ventilatory reflex, and the role of nitric oxide (NO). Pharmacological treatment presents some beneficial effects on the frequency of respiratory events and sleep architecture. Nonetheless, objective data assessing snoring and daytime sleepiness are still necessary. Nasal surgery can improve the quality of life and snoring in a select group of patients with mild OSAS and septal deviation but is not an effective treatment for OSA as such. Despite the conflicting results in the literature, it is important that patients who are not perfectly adapted to CPAP are evaluated in detail, in order to identify whether there are obstructive factors that could be surgically corrected.

Chronic intestinal pseudo-obstructive (CIPO) conditions are considered the most severe disorders of gut motility. They continue to present significant challenges in clinical care despite considerable recent progress in our understanding of pathophysiology, resulting in unacceptable levels of morbidity and mortality. Major contributors to the disappointing lack of progress in paediatric CIPO include a dearth of clarity and uniformity across all aspects of clinical care from definition and diagnosis to management. In order to assist medical care providers in identifying, evaluating, and managing children with CIPO, experts in this condition within the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition as well as selected external experts, were charged with the task of developing a uniform document of evidence- and consensus-based recommendations. Ten clinically relevant questions addressing terminology, diagnostic, therapeutic, and prognostic topics were formulated. A systematic literature search was performed from inception to June 2017 using a number of established electronic databases as well as repositories. The approach of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) was applied to evaluate outcome measures for the research questions. Levels of evidence and quality of evidence were assessed using the classification system of the Oxford Centre for Evidence-Based Medicine (diagnosis) and the GRADE system (treatment). Each of the recommendations were discussed, finalized, and voted upon using the nominal voting technique to obtain consensus. This evidence- and consensus-based position paper provides recommendations specifically for chronic intestinal pseudo-obstruction in infants and children. It proposes these be termed paediatric intestinal pseudo-obstructive (PIPO) disorders to distinguish them from adult onset CIPO. The manuscript provides guidance on the diagnosis, evaluation, and treatment of children

Neonatal intestinal obstruction due to a tumour is rare. We report a six-day-old male neonate who presented with abdominal distension and vomiting. Laparotomy revealed colonic obstruction caused by a stenosing fibrotic lesion in the proximal transverse colon. Histopathological examination of the resected specimen confirmed fibromatosis. We believe this represents the third reported case of solitary colonic fibromatosis. The literature on neonatal intestinal fibromatosis is reviewed.

2018-06-01

Our aim in this study was to analyze whether soft palate length and velum obstruction during sleep are correlated and to determine the effects of related parameters on obstructive sleep apnea syndrome (OSAS) severity. We used computed tomography to measure soft palate length and drug-induced sleep endoscopy (DISE) to evaluate velum obstruction severity. Patients also underwent polysomnography (PSG) for evaluation of OSAS severity. A retrospective cohort of 67 patients with OSAS treated between May 1st, 2013 and July 31st, 2016 was analyzed. Each patient underwent DISE, PSG, and computed tomography. Using DISE, velum obstruction was categorized by the VOTE classification method. Using computed tomography, soft palate length was measured as the length of the posterior nasal spine to the uvula. Correlations of velum obstruction in DISE and PSG parameters (obstructive apnea, hypopnea, apnea hypopnea index (AHI), respiratory effort related arousal (RERA), respiratory disturbance index (RDI), baseline SaO 2 , and minimum SaO 2 ) with soft palate length were also analyzed. Among the 67 patients, the average PNS-U length was 39.90±4.19mm. Length was significantly different by age but not by other demographic characteristics such as sex, past history, or BMI. DISE revealed a statistically significant difference of velum obstruction degree; the cutoff value for PNS-U was 39.47mm. The PSG results, obstructive apnea, AHI, RDI, baseline SaO 2 , and minimum SaO 2 were correlated with PNS-U length, while other results such as hypopnea and RERA showed no correlation. Analysis of soft palate length showed that increased PNS-U length was associated with higher rates of obstructive apnea, AHI, and RDI as assessed by PSG. In contrast, lower baseline SaO 2 and minimum SaO 2 values were seen by PSG; more severe velum obstruction was seen by DISE. We propose that when a soft palate is suspected in OSAS, computed tomography measurement of soft palate length is a valid method for

Patients suffering from chronic idiopathic intestinal pseudo-obstruction (CIIPO) clearly benefit from home parenteral nutrition (HPN) to maintain adequate nutritional status and general health. But intestinal dismotility can seriously disturb their quality of life (QOL) to the point of making it intolerable. Report our clinical experience on the management of chronic severe occlusive symptoms in CIIPO by near total small bowel resection. A 20-year retrospective study of eight patients with end-stage CIIPO maintained on HPN and suffering of chronic occlusive symptoms refractory to medical treatment underwent extensive small bowel resection preserving less than 70 cm of total small bowel and less than 20 cm of ileum. The jejunum was anastomosed either to the ileum or to the colon. Six patients were completely relieved from obstructive symptoms. Two patients needed a second operation to remove the residual ileum because of recurrent symptoms. Two were significantly improved. There was no post-operative death. All patients experienced a significant improvement in their QOL. Near total small bowel resection appears to be a safe and effective procedure in end-stage CIIPO patients, refractory to optimal medical treatment.

Increasing evidence suggests that the intestinal microbiota is closely correlated with the host's health status. Thus, a serious disturbance that disrupts the stability of the intestinal microecosystem could cause host disease. Shrimps are one of the most important products among fishery trading commodities. However, digestive system diseases, such as white feces syndrome (WFS), frequently occur in shrimp culture and have led to enormous economic losses across the world. The WFS occurrences are unclear. Here, we compared intestinal bacterial communities of WFS shrimp and healthy shrimp. Intestinal bacterial communities of WFS shrimp exhibited less diversity but were more heterogeneous than those of healthy shrimp. The intestinal bacterial communities were significantly different between WFS shrimp and healthy shrimp; compared with healthy shrimp, in WFS shrimp, Candidatus Bacilloplasma and Phascolarctobacterium were overrepresented, whereas Paracoccus and Lactococcus were underrepresented. PICRUSt functional predictions indicated that the relative abundances of genes involved in energy metabolism and genetic information processing were significantly greater in WFS shrimp. Collectively, we found that the composition and predicted functions of the intestinal bacterial community were markedly shifted by WFS. Significant increases in Candidatus Bacilloplasma and Phascolarctobacterium and decreases in Paracoccus and Lactococcus may contribute to WFS in shrimp.

Psychological comorbidity is highly present in irritable bowel syndrome (IBS). Recent research points to a role of intestinal microbiota in visceral hypersensitivity, anxiety, and depression. Increased disease reactivity to psychological stress has been described too. A few clinical studies have attempted to identify features of dysbiosis in IBS. While animal studies revealed strong associations between stress and gut microbiota, studies in humans are rare. This review covers the most important studies on intestinal microbial correlates of psychological and clinical features in IBS, including stress, anxiety, and depression.

Ehlers-Danlos syndrome is a rare clinical condition caused by a genetic change that results in the formation of structurally or functionally altered collagen. The clinical manifestations are varied, being the most obvious skin hypermotility and increased joint flexibility, although other systems - such as cardiovascular, respiratory and neurological - may also be affected. This paper presents the report of a patient who sought medical attention with complaints of atypical chest pain. Clinical evaluation enabled hypothetical diagnosis of hypertrophic obstructive cardiomyopathy and Ehlers-Danlos syndrome. Initial electrocardiogram, echocardiogram and 24 hours holter allowed the confirmation of the first hypothesis. A skin biopsy performed later associated clinical data and confirmed the second hypothesis. PMID:26312722

Recurrent intestinal volvulus in midgut malrotation causing acute bowel obstruction: A case report

Intestinal malrotation occurs when there is a disruption in the normal embryological development of the bowel. The majority of patients present with clinical features in childhood, though rarely a first presentation can take place in adulthood. Recurrent bowel obstruction in patients with previous abdominal operation for midgut malrotation is mostly due to adhesions but very few reported cases have been due to recurrent volvulus. We present the case of a 22-year-old gentleman who had laparotomy in childhood for small bowel volvulus and then presented with acute bowel obstruction. Preoperative computerised tomography scan showed small bowel obstruction and features in keeping with midgut malrotation. Emergency laparotomy findings confirmed midgut malrotation with absent appendix, abnormal location of caecum, ascending colon and small bowel. In addition, there were small bowel volvulus and a segment of terminal ileal stricture. Limited right hemicolectomy was performed with excellent postoperative recovery. This case is presented to illustrate a rare occurrence and raise an awareness of the possibility of dreadful recurrent volvulus even several years following an initial Ladd’s procedure for midgut malrotation. Therefore, one will need to exercise a high index of suspicion and this becomes very crucial in order to ensure prompt surgical intervention and thereby preventing an attendant bowel ischaemia with its associated high fatality.

An update on cardiovascular effects of obstructive sleep apnoea syndrome.

PubMed

Uyar, Meral; Davutoglu, Vedat

2016-09-01

Obstructive sleep apnoea syndrome is an important health problem which may cause or worsen systemic diseases. Chronic intermittent hypoxia during repetitive airflow cessations may cause endothelial dysfunction. Sleep apnoea is also shown to be associated with hypercoagulability which may be due to decreased nitric oxide levels and impaired vasodilatation. Endothelial dysfunction, increased systemic inflammation, sympathetic nervous system activation, increased oxidative stress and dysglycaemia may all contribute to cardiovascular processes such as hypertension, arrhythmia, stroke, heart failure and coronary artery disease in patients with obstructive sleep apnoea. Treatment approaches in patients with obstructive sleep apnoea mainly focus on maintaining upper airway patency either with positive airway pressure devices or upper airway appliances. Strategies involving positive airway pressure therapy are associated with decreased morbidity and mortality. Obstructive sleep apnoea should be suspected as an underlying mechanism in patients with cardiovascular disease and warrants appropriate treatment. Published by the BMJ Publishing Group Limited.

A number of disorders have been described to cause protein losing enteropathy (PLE) in children. Primary intestinal lymphangiectasia (PIL) is one mechanism leading to PLE. Few syndromes are associated with PIL; Hennekam syndrome (HS) is one of them. The principal treatment for PIL is a high protein, low fat diet with medium chain triglycerides supplementation. Supportive therapy includes albumin infusion. Few publications have supported the use of octreotide to diminish protein loss and minimize hypoalbuminemia seen in PIL. There are no publications on the treatment of PIL with octreotide in patients with HS. We report two children with HS and PLE in which we used octreotide to decrease intestinal protein loss. In one patient, octreotide increased serum albumin to an acceptable level without further need for albumin infusions. The other patient responded more dramatically with near normal serum albumin levels and cessation of albumin infusions. In achieving a good response to octreotide in both patients, we add to the publications supporting the use of octreotide in PIL and suggest that octreotide should be tried in patients with PIL secondary to HS. To the best of our knowledge, this is the first case report on the use of octreotide in HS-associated PIL.

Maternally inherited diabetes and deafness (MIDD) has been related to an A to G transition in the mitochondrial tRNA Leu (UUR) gene at the base pair 3243. This subtype of diabetes is characterized by maternal transmission, young age at onset and bilateral hearing impairment. Besides diabetes and deafness, the main diagnostic features, a wide range of multisystemic symptoms may be associated with the A3243G mutation. Organs that are most metabolically active, such as muscles, myocardium, retina, cochlea, kidney and brain are frequently affected. Gastrointestinal tract symptoms are also common in patients with mitochondrial disease and constipation and diarrhea are the most frequent manifestations. However, there are few prior reports of intestinal pseudo obstruction in MIDD patients. Here we report the case of a patient with MIDD associated with the mtDNA A3243G mutation who developed chronic intestinal pseudo obstruction, and the introduction of Coenzyme Q10 as adjunctive therapy led to a solution of the pseudo obstruction.

Acute GI obstruction.

PubMed

Hucl, Tomas

2013-10-01

Acute gastrointestinal obstruction occurs when the normal flow of intestinal contents is interrupted. The blockage can occur at any level throughout the gastrointestinal tract. The clinical symptoms depend on the level and extent of obstruction. Various benign and malignant processes can produce acute gastrointestinal obstruction, which often represents a medical emergency because of the potential for bowel ischemia leading to perforation and peritonitis. Early recognition and appropriate treatment are thus essential. The typical clinical symptoms associated with obstruction include nausea, vomiting, dysphagia, abdominal pain and failure to pass bowel movements. Abdominal distention, tympany due to an air-filled stomach and high-pitched bowel sounds suggest the diagnosis. The diagnostic process involves imaging including radiography, ultrasonography, contrast fluoroscopy and computer tomography in less certain cases. In patients with uncomplicated obstruction, management is conservative, including fluid resuscitation, electrolyte replacement, intestinal decompression and bowel rest. In many cases, endoscopy may aid in both the diagnostic process and in therapy. Endoscopy can be used for bowel decompression, dilation of strictures or placement of self-expandable metal stents to restore the luminal flow either as a final treatment or to allow for a delay until elective surgical therapy. When gastrointestinal obstruction results in ischemia, perforation or peritonitis, emergency surgery is required. Copyright © 2013. Published by Elsevier Ltd.

To evaluate the upper airway characteristics in the early postoperative period after maxilomandibular advancement for obstructive sleep apnea syndrome. Nasopharyngolaryngoscopy was performed before and 48 hours after surgery on 70 consecutive patients who underwent maxillomandibular advancement for obstructive sleep apnea syndrome. The preoperative and the postoperative evaluations were performed by the same examiner for consistency. Mild to moderate lateral pharyngeal wall edema was identified in 70 consecutive patients. Fourteen patients (20%) had edema as well as ecchymosis involving the pyriform sinus and aryepiglottic fold. Four of these patients (6%) were also noted to have hypopharyngeal hematoma involving the pyriform sinus, aryepiglottic fold, arytenoid, and false vocal cord that partially obstructed the airway. These four patients were closely monitored for 1 to 2 additional days for possible expanding hematoma leading to airway compromise. None of these patients were found to have airway difficulty, and the minimum oxygen saturation was more than 90% throughout the hospitalization. All four patients were discharged uneventfully, and the hematoma resolved completely within 10 days. Although postoperative edema was expected after maxillomandibular advancement, hypopharyngeal hematoma was unexpected. Although none of our patients had evidence of airway difficulty, the possibility of an expanding hypopharyngeal hematoma should be considered in patients complaining of breathing difficulty after maxillomandibular advancement surgery.

Assessing the severity of glossopharyngeal obstruction is important for the diagnosis and therapy of obstructive sleep apnea hypopnea syndrome (OSAHS). The polysomnography (PSG) with nasopharyngeal tube insertion (NPT-PSG) has shown good results in assessing glossopharyngeal obstruction. The objective of this study was to compare NPT-PSG with Friedman tongue position (FTP) classification which was also used to evaluate the glossopharyngeal obstruction. One hundred and five patients with OSAHS diagnosed by PSG were included in the study. All the patients were successfully examined by NPT-PSG. Based on the grade of FTP classification, 105 patients were divided into four groups. The differences of the general clinical data, PSG and NPT-PSG results were analyzed among the four groups. And the coincidence of diagnosing glossopharyngeal obstruction of two methods was calculated. There was no significant difference among the four groups in general clinical data and PSG results. However, NPT-PSG results were significantly different among the four groups. Following with the increasing FTP, apnea hypopnea index increased and lowest saturation of blood oxygen decreased. There were 38 patients with and other 38 patients without glossopharyngeal obstruction diagnosed by both methods. The coincidence of two methods was 72.4 %. NPT-PSG is an easy and effective method in assessing the severity of glossopharyngeal obstruction. The coincidence between the NPT-PSG and FTP classification is good. But in some special OSAHS patients such as glossoptosis, unsuccessful uvulopalatopharyngoplasty or suspicious pachyglossia, NPT-PSG is better than FTP classification.

The narrowing pattern of the upper airway in obstructive sleep apnea patients may be different in sleep as compared with awake. Three different types of obstruction were observed in these subjects during drug-induced sleep. The different obstruction pattern during drug-induced sleep suggests that different strategies should be selected in upper airway management. To identify the sites of narrowing and evaluate dynamic upper airway movement in patients with obstructive sleep apnea syndrome (OSAS) while awake and asleep. This study included 10 patients treated for OSAS between August 2003 and June 2004. Overnight polysomnography was performed on all patients. Parameters including gender, age, neck circumference, and body mass index were recorded. Ultra-fast MRI during awake and drug-induced sleep was arranged to evaluate the dynamic motion of the upper airway. The narrowing pattern of the upper airway during awake differed from the narrowing pattern during drug-induced sleep in 3 of 10 subjects. Three different types, palatal obstruction, combined upper and lower pharyngeal obstruction, and circumferential obstruction of the upper airway, were observed in these patients during drug-induced sleep.

Neonatal small left colon syndrome in the offspring of diabetic mothers-an analysis of 105 children.

2009-12-01

Neonatal small left colon syndrome (NSLCS) is considered a rare cause of neonatal intestinal obstruction, with few documented cases in the English literature. Maternal diabetes has been reported in 40% to 50% of the published cases of NSLCS. Currently, the incidence of maternal diabetes is increasing, but there has been no study to ascertain the incidence and significance of NSLCS in this population. This review aims to assess the current significance of NSLCS and its association with maternal diabetes. This was a retrospective review of 105 offspring of diabetic mothers who were admitted during the period 2004 to 2008 to our neonatal unit with special emphasis on associated NSLCS. There were 6 cases of intestinal obstruction in this group of 105 children. Five children, including a pair of twins, had classic features of NSLCS as demonstrated in the contrast enema with an abrupt transition at the splenic flexure and a narrow left colon. Conservative treatment was successful in all, negating the need for further invasive investigation. The sixth child had rectosigmoid Hirschprung disease. During the study period, there were no other cases of NSLCS in the nondiabetic population. Neonatal small left colon syndrome is the most common cause of intestinal obstruction in offspring of diabetic mothers. Neonatal small left colon syndrome can be confidently diagnosed in this population based on the classic clinical and radiologic findings. The incidence of NSLCS can be expected to increase as the incidence of maternal diabetes increases.

Intestinal microbiota in pathophysiology and management of irritable bowel syndrome

PubMed Central

Lee, Kang Nyeong; Lee, Oh Young

2014-01-01

Irritable bowel syndrome (IBS) is a functional bowel disorder without any structural or metabolic abnormalities that sufficiently explain the symptoms, which include abdominal pain and discomfort, and bowel habit changes such as diarrhea and constipation. Its pathogenesis is multifactorial: visceral hypersensitivity, dysmotility, psychosocial factors, genetic or environmental factors, dysregulation of the brain-gut axis, and altered intestinal microbiota have all been proposed as possible causes. The human intestinal microbiota are composed of more than 1000 different bacterial species and 1014 cells, and are essential for the development, function, and homeostasis of the intestine, and for individual health. The putative mechanisms that explain the role of microbiota in the development of IBS include altered composition or metabolic activity of the microbiota, mucosal immune activation and inflammation, increased intestinal permeability and impaired mucosal barrier function, sensory-motor disturbances provoked by the microbiota, and a disturbed gut-microbiota-brain axis. Therefore, modulation of the intestinal microbiota through dietary changes, and use of antibiotics, probiotics, and anti-inflammatory agents has been suggested as strategies for managing IBS symptoms. This review summarizes and discusses the accumulating evidence that intestinal microbiota play a role in the pathophysiology and management of IBS. PMID:25083061

Autoimmune polyglandular syndromes (APS) comprise a wide clinical spectrum of autoimmune disorders. APS is divided into Type I, Type II, Type I and Type IV depending upon the pattern of disease combination. Ghronic diarrhoea is one of the many manifestations of APS and many aetiological factors have been suggested for it. Apart from the established aetiological factors, intestinal lymphangiectasia may be responsible for chronic diarrhea in some cases.Intestinal lymphangiectasia has been reported in Type I APS. We report a case of Type III APS with hypocalcaemia and hypothyroidism who had chronic diarrhea of long duration and was finally diagnosed to have intestinal lymphangiectasia.

Metamemory beliefs and episodic memory in obstructive sleep apnea syndrome.

PubMed

Daurat, Agnès; Huet, Nathalie; Tiberge, Michel

2010-08-01

This study assessed metamemory and its role in actual episodic memory performance in 26 patients with obstructive sleep apnea syndrome and 27 healthy controls. Metamemory knowledge and memory beliefs were assessed using the Metamemory Inventory in Adulthood. Episodic memory performance was investigated with the Remember/Know paradigm. Subjective sleepiness was evaluated. Patients underwent a polysomnographic assessment. In contrast to the control group's more stable memory beliefs, patients self-assessed their memory as declining across time, and felt more anxious about their memory. There was only a modest difference between patients' self-perceptions of their memory capacities and those of the control group, but patients' actual memory performance was strongly disturbed. While the latter was significantly correlated with severity of obstructive sleep apnea, scores on the Metamemory Inventory in Adulthood scales were not correlated with physiological measures, subjective sleepiness, or episodic memory performance. Obstructive sleep apnea may affect prefrontal cortex functioning and hence the ability to assess one's own memory impairment.

Primary chronic intestinal pseudo-obstruction (CIPO) is a rare, potentially life-threatening disorder characterized by severely impaired gastrointestinal motility. The objective of this study was to examine the contribution of ACTG2, LMOD1, MYH11, and MYLK mutations in an Australasian cohort of patients with a diagnosis of primary CIPO associated with visceral myopathy. Pediatric and adult patients with primary CIPO and suspected visceral myopathy were recruited from across Australia and New Zealand. Sanger sequencing of the genes encoding enteric gamma-actin (ACTG2) and smooth muscle leiomodin (LMOD1) was performed on DNA from patients, and their relatives, where available. MYH11 and MYLK were screened by next-generation sequencing. We identified heterozygous missense variants in ACTG2 in 7 of 17 families (~41%) diagnosed with CIPO and its associated conditions. We also identified a previously unpublished missense mutation (c.443C>T, p.Arg148Leu) in one family. One case presented with megacystis-microcolon-intestinal hypoperistalsis syndrome in utero with subsequent termination of pregnancy at 28 weeks' gestation. All of the substitutions identified occurred at arginine residues. No likely pathogenic variants in LMOD1, MYH11, or MYLK were identified within our cohort. ACTG2 mutations represent a significant underlying cause of primary CIPO with visceral myopathy and associated phenotypes in Australasian patients. Thus, ACTG2 sequencing should be considered in cases presenting with hypoperistalsis phenotypes with suspected visceral myopathy. It is likely that variants in other genes encoding enteric smooth muscle contractile proteins will contribute further to the genetic heterogeneity of hypoperistalsis phenotypes. © 2018 John Wiley & Sons Ltd.

Loss of significant intestinal length from congenital anomaly or disease may lead to short bowel syndrome (SBS); intestinal failure may be partially offset by a gain in epithelial surface area, termed adaptation. Current in vivo models of SBS are costly and technically challenging. Operative times and survival rates have slowed extension to transgenic models. We created a new reproducible in vivo model of SBS in zebrafish, a tractable vertebrate model, to facilitate investigation of the mechanisms of intestinal adaptation. Proximal intestinal diversion at segment 1 (S1, equivalent to jejunum) was performed in adult male zebrafish. SBS fish emptied distal intestinal contents via stoma as in the human disease. After 2 wk, S1 was dilated compared with controls and villus ridges had increased complexity, contributing to greater villus epithelial perimeter. The number of intervillus pockets, the intestinal stem cell zone of the zebrafish increased and contained a higher number of bromodeoxyuridine (BrdU)-labeled cells after 2 wk of SBS. Egf receptor and a subset of its ligands, also drivers of adaptation, were upregulated in SBS fish. Igf has been reported as a driver of intestinal adaptation in other animal models, and SBS fish exposed to a pharmacological inhibitor of the Igf receptor failed to demonstrate signs of intestinal adaptation, such as increased inner epithelial perimeter and BrdU incorporation. We describe a technically feasible model of human SBS in the zebrafish, a faster and less expensive tool to investigate intestinal stem cell plasticity as well as the mechanisms that drive intestinal adaptation.

To investigate the symptoms most frequently found in children with a polysomnographic diagnosis of obstructive sleep apnea-hypopnea syndrome (OSAHS). We evaluated 38 children consecutively referred to the sleep laboratory with suspicion of OSAHS between June of 2003 and December of 2004. The patients were submitted to a pre-sleep questionnaire and to polysomnography. The mean age was 7.8 +/- 4 years (range, 2-15 years), and 50% of the children were male. Children without apnea accounted for 7.9% of the sample. The obstructive sleep apnea observed in the remainder was mild in 42.1%, moderate in 28.9% and severe in 22.1%. Severe cases of apnea were most common among children under the age of six (pre-school age). In children with OSAHS, the most common symptoms were snoring and nasal obstruction, which were observed in 74.3 and 72.7% of the children, respectively. Excessive sleepiness and bruxism were seen in 29.4 and 34.3%, respectively, and reflux disease was seen in only 3.1%. Restless legs and difficulty in falling asleep were identified in 65 and 33%, respectively. All of the children diagnosed with severe OSAHS also presented snoring and bruxism. Snoring and nasal obstruction were the most common symptoms found in our sample of children and adolescents with OSAHS. In addition, OSAHS severity was associated with being in the lower age bracket.

This study aimed to compare the efficiency of the STOP-BANG and Berlin Obstructive Sleep Apnoea Syndrome questionnaires for evaluating potential respiratory complications during the perioperative period. Questionnaires that are used to determine obstructive sleep apnoea risk are not widely used for surgical patients. Among the questionnaires that are commonly used for obstructive sleep apnoea screening, it remains unclear whether the STOP-BANG or Berlin Obstructive Sleep Apnoea Syndrome questionnaire is more effective in terms of ease of use, usage period and diagnosis of surgical patients with obstructive sleep apnoea risk. This study was designed as a descriptive and prospective study. The study included 126 patients over 18 years of age who were American Society of Anesthesiologists classification class I-II and underwent laparoscopic cholecystectomy. To determine the potential obstructive sleep apnoea syndrome risk, the STOP-BANG and Berlin questionnaires were administered. Respiratory complications were then observed during the perioperative period. During intubation and extubation, we observed statistically significant differences in difficult intubation, difficult facemask ventilation and desaturation frequency between the high- and low-risk groups for obstructive sleep apnoea syndrome, as determined by the STOP-BANG questionnaire. During extubation, statistically significant differences in coughing, breath-holding and desaturation frequency were observed between the high-risk and low-risk groups, according to the Berlin questionnaire. In the post-anaesthesia care unit, both questionnaires found statistically significant differences between the low- and high-risk groups. Obstructive sleep apnoea syndrome screening questionnaires administered during the preoperative period are useful for predicting perioperative respiratory complications. It may be most useful to administer the STOP-BANG questionnaire as the initial evaluation. Questionnaires may be used to

We report a case of obstructive sleep apnea that occurred as a result of Forestier disease and describe the surgical treatment that was performed. The patient is a 56-year-old man who presented dysphagia for solids and liquids, snoring (score 10) and excessive daytime sleepiness for 5 years. On fiber optic laryngoscopy examination, there was interarytenoid edema and protrusion of the posterior wall of the larynx. The cervical X-Ray showed protrusion of intervertebral disc between C3-C5 (skeletal hyperostosis) and the polysomnography revealed apnea-hypopnea index (AHI) of 56 events/h. Surgery was performed by the otorhinolaryngology and orthopedic teams. The patient evolved with complete symptom resolution and an AHI of 3,9 events/h on the control polysomnography. This is the first reported case of Forestier Syndrome (FS) associated with Obstructive Sleep Apnea (OSA) that was proposed surgical treatment and the patient evolved with complete symptom improvement.

Intussusception is defined as telescoping of a segment of gastrointestinal tract into an adjacent one. In small children, it is the commonest cause of intestinal obstruction. More than 90% of childhood intussusceptions are idiopathic. We report a rare case of localized small intestinal lymphangiectasia, presenting as intussusception in a 6-month-old male child. The child presented with features of acute intestinal obstruction for which he was later operated. The gross examination of excised ileocecal mass revealed intussusception. Histopathologic examination revealed lymphangiectasia of small intestine, which acted as a lead point for ileocecal intussusception. Postoperative period was uneventful.

AIM: To investigate the effects of propolis on bacterial translocation and ultrastructure of intestinal morphology in experimental obstructive jaundice. METHODS: Thirty Wistar-Albino male rats were randomly divided into three groups, each including 10 animals: groupI, sham-operated; group II, ligation and division of the common bile duct (BDL); group III, BDL followed by oral supplementation of propolis 100 mg/kg per day. Liver, blood, spleen, mesenteric lymph nodes, and ileal samples were taken for microbiological, light and transmission electron microscopic examination on postoperative 7th d after sacrification. RESULTS: The mean number of villi per centimeter and mean mucosal height of the propolis group were significantly different in the BDL group (P = 0.001 and 0.012, respectively). The electron microscopic changes were also different between these groups. Sham and BDL + propolis groups had similar incidence of bacterial translocation (BT). The BDL group had significantly higher rates of BT as compared with sham and BDL + propolis groups. BT was predominantly detected in MLNs and the most commonly isolated bacteria was Escherichia coli. CONCLUSION: Propolis showed a significant protective effect on ileal mucosa and reduced bacterial translocation in the experimental obstructive jaundice model. Further studies should be carried out to explain the mechanisms of these effects. PMID:17876893

AIM: To evaluate the effects of honey on bacterial translocation and intestinal villus histopathology in experimental obstructive jaundice. METHODS: Thirty Wistar-Albino rats were randomly divided into three groups each including 10 animals: group I, sham-operated; group II, ligation and section of the common bile duct (BDL); group III, bile duct ligation followed by oral supplementation of honey (BDL + honey) 10 g/kg per day. Liver, blood, spleen, mesenteric lymph nodes, and ileal samples were taken for microbiological, light and transmission electrone microscopic examination. RESULTS: Although the number of villi per centimeter and the height of the mucosa were higher in sham group, there was no statistically significant difference between sham and BDL + honey groups (P > 0.05). On the other hand, there was a statistically significant difference between BDL group and other groups (P < 0.05). The electron microscopic changes were also different between these groups. Sham and honey groups had similar incidence of bacterial translocation (P > 0.05). BDL group had significantly higher rates of bacterial translocation as compared with sham and honey groups. Bacterial translocation was predominantly detected in mesenteric lymph nodes. CONCLUSION: Supplementation of honey in presence of obstructive jaundice ameliorates bacterial translocation and improves ileal morphology. PMID:18528939

Intestinal transplantation: The anesthesia perspective.

PubMed

Dalal, Aparna

2016-04-01

Intestinal transplantation is a complex and challenging surgery. It is very effective for treating intestinal failure, especially for those patients who cannot tolerate parenteral nutrition nor have extensive abdominal disease. Chronic parental nutrition can induce intestinal failure associated liver disease (IFALD). According to United Network for Organ Sharing (UNOS) data, children with intestinal failure affected by liver disease secondary to parenteral nutrition have the highest mortality on a waiting list when compared with all candidates for solid organ transplantation. Intestinal transplant grafts can be isolated or combined with the liver/duodenum/pancreas. Organ Procurement and Transplantation Network (OPTN) has defined intestinal donor criteria. Living donor intestinal transplant (LDIT) has the advantages of optimal timing, short ischemia time and good human leukocyte antigen matching contributing to lower postoperative complications in the recipient. Thoracic epidurals provide excellent analgesia for the donors, as well as recipients. Recipient management can be challenging. Thrombosis and obstruction of venous access maybe common due to prolonged parenteral nutrition and/or hypercoaguability. Thromboelastography (TEG) is helpful for managing intraoperative product therapy or thrombosis. Large fluid shifts and electrolyte disturbances may occur due to massive blood loss, dehydration, third spacing etc. Intestinal grafts are susceptible to warm and cold ischemia and ischemia-reperfusion injury (IRI). Post-reperfusion syndrome is common. Cardiac or pulmonary clots can be monitored with transesophageal echocardiography (TEE) and treated with recombinant tissue plasminogen activator. Vasopressors maybe used to ensure stable hemodynamics. Post-intestinal transplant patients may need anesthesia for procedures such as biopsies for surveillance of rejection, bronchoscopy, endoscopy, postoperative hemorrhage, anastomotic leaks, thrombosis of grafts etc. Asepsis

Objective This purpose of this case study is to describe a natural method to help in management of obstructive sleep apnea syndrome (OSAS), which is known to be a common and debilitating condition. Clinical Features Obstructive sleep apnea syndrome is typically managed with a continuous positive airway pressure (CPAP) device, which the patient wears during sleep to help maintain respiration. This report describes the chiropractic management and resolution of OSAS with dietary modifications in a 55-year-old man who wore a CPAP for 10 years. Intervention and Outcome After adhering to dietary modifications for 3 months, the patient no longer required the use of the CPAP device and continues to have a normal active lifestyle almost 7 years later. Conclusion Dietary modifications may be an effective tool to improve the management of OSAS. PMID:22014867

We report on two patients with recurrent episodes of chronic intestinal pseudo-obstruction (CIPO). A 50-year-old woman with severe multiple sclerosis and an 84-year-old man with Parkinson's disease and dementia had multiple hospital admissions because of pain and distended abdomen. Radiographic and endoscopic findings showed massive dilation of the colon without any evidence of obstruction. Conservative management resolved symptoms only for a short period of time. As these patients were poor candidates for any surgical treatment we carried out percutaneous endoscopic colostomy by placing a 20-Fr tube in the cecum with the introducer method. The procedure led to durable symptom relief without complications. We present these two cases and give a review through the existing literature of the procedure in CIPO. © 2015 Japan Gastroenterological Endoscopy Society.

Off-site consultations by board-certified veterinary radiologists benefit residents and emergency clinicians by providing immediate feedback and potentially improving patient outcome. Smartphone devices and compressed images transmitted by email or text greatly facilitate availability of these off-site consultations. Criticism of a smartphone interface for off-site consultation is mostly directed at image degradation relative to the standard radiographic viewing room and monitors. The purpose of this retrospective, cross-sectional, methods comparison study was to compare the accuracy of abdominal radiographs in two imaging interfaces (Joint Photographic Experts Group, off-site, smartphone vs. Digital Imaging and Communications in Medicine, on-site, standard workstation) for the diagnosis of small intestinal mechanical obstruction in vomiting dogs and cats. Two board-certified radiologists graded randomized abdominal radiographs using a five-point Likert scale for the presence of mechanical obstruction in 100 dogs or cats presenting for vomiting. The area under the receiver operator characteristic curves for both imaging interfaces was high. The accuracy of the smartphone and traditional workstation was not statistically significantly different for either reviewer (P = 0.384 and P = 0.536). Correlation coefficients were 0.821 and 0.705 for each reviewer when the same radiographic study was viewed in different formats. Accuracy differences between radiologists were potentially related to years of experience. We conclude that off-site expert consultation with a smartphone provides an acceptable interface for accurate diagnosis of small intestinal mechanical obstruction in dogs and cat. © 2016 American College of Veterinary Radiology.

OBJECTIVES: This study evaluated the effect of Continuous Positive Airway Pressure treatment on oxidative stress parameters and the quality of life of elderly patients with obstructive sleep apnea syndrome. METHODS: In total, 30 obstructive sleep apnea syndrome patients and 27 subjects without obstructive sleep apnea syndrome were included in this study. Both groups underwent quality of life and oxidative stress evaluations at baseline and after six months. Polysomnography was performed in both groups at baseline and a second time in the obstructive sleep apnea syndrome group after six months of Continuous Positive Airway Pressure treatment. All of the variables were compared between the control and obstructive sleep apnea syndrome groups in this prospective case-control study. RESULTS: The baseline concentrations of the antioxidant enzyme catalase were higher in the obstructive sleep apnea syndrome group than the control group. After Continuous Positive Airway Pressure treatment, the obstructive sleep apnea syndrome group exhibited a reduction in the level of oxidative stress, as indicated by a decrease in the level of lipid peroxidation measured by the malondialdehyde (MDA) concentration [pre: 2.7 nmol malondialdehyde/mL (95% 1.6-3.7) vs. post: 1.3 nmol MDA/mL (0.7-1.9), p<0.01]. Additionally, improvements were observed in two domains covered by the SF-36 questionnaire: functional capacity [pre: 77.4 (69.2-85.5) vs. post: 83.4 (76.9-89.9), p = 0.002] and pain [pre: 65.4 (52.8-78.1) vs. post: 77.8 (67.2-88.3), p = 0.004]. CONCLUSION: Our study demonstrated that the use of Continuous Positive Airway Pressure to treat obstructive sleep apnea syndrome in elderly patients reduced oxidative stress and improved the quality of life.

Intestinal Membrane Permeability and Hypersensitivity In the Irritable Bowel Syndrome

PubMed Central

Zhou, QiQi; Zhang, Buyi; Verne, G. Nicholas

2009-01-01

Irritable bowel syndrome (IBS) is a common gastrointestinal disorder in which the underlying pathophysiology is poorly understood; however, increased intestinal permeability in diarrhea-predominant IBS patients has been reported. Here we demonstrate diarrhea-predominant IBS patients (D-IBS) that display increased intestinal permeability. We have also found that increased intestinal membrane permeability is associated with visceral and thermal hypersensitivity in this subset of D-IBS patients. We evaluated 54 D-IBS patients and 22 controls for intestinal membrane permeability using the lactulose / mannitol method. All subjects ingested 5 g laclulose and 2 g mannitol in 100 ml of water after which their urine was collected. We also evaluated the mean mechanical visual analogue (MVAS) pain rating to nociceptive thermal and visceral stimulation in all subjects. All study participants also completed the FBDSI scale. Approximately 39% of diarrhea-predominant IBS patients have increased intestinal membrane permeability as measured by the lactulose / mannitol ratio. These IBS patients also demonstrated higher M-VAS pain intensity reading scale. Interestingly, the IBS patients with hypersensitivity and increased intestinal permeability had a higher FBDSI score (100.8±5.4) compared to IBS patients with normal membrane permeability and sensitivity (51.6±12.7) and controls (6.1 ± 5.6) (p<0.001). A subset of D-IBS patients have increased intestinal membrane permeability that is associated with an increased FBDSI score and increased hypersensitivity to visceral and thermal nociceptive pain stimuli. Thus, increased intestinal membrane permeability in D-IBS patients may lead to more severe IBS symptoms and hypersensitivity to somatic and visceral stimuli. PMID:19595511

Bezoars are an unusual cause of acute intestinal obstruction in children. Most cases are trichobezoars in adolescent girls who swallow their hair. Lactobezoars are another unusual but occasionally reported cause of intestinal obstruction in neonates. Phytobezoars and food bolus bezoars are the least common types of intestinal obstruction that have been reported in children. Of the few paediatric cases that have been described, the majority involve persimmons. Moreover, all of these cases involve the ingestion of raw fibres or fruit that have not been cooked. We report a case of a girl who presented with acute ileal obstruction because of lentil soup bezoar. Given the wide use of this otherwise nutritional foodstuff, we highlight the danger from its inappropriate preparation to the health of children. This is the first reported case of intestinal obstruction caused by lentils in children and we hope to raise concern among paediatricians regarding this matter. PMID:24692381

The interaction among heart failure (HF), chronic kidney disease (CKD), and anemia is called cardio-renal anemia syndrome. The mechanism of anemia in cardio-renal anemia syndrome is complex and remains completely unknown. We have previously reported that impaired intestinal iron transporters may contribute to the mechanism of anemia in HF using in vivo HF model rats. In this study, we assessed intestinal iron transporters in CKD model rats to investigate the association of intestinal iron transporters in the mechanism of cardio-renal anemia syndrome. CKD was induced by 5/6 nephrectomy in Sprague-Dawley rats. Sham-operated rats served as a control. After 24-week surgery, CKD rats exhibited normocytic normochromic anemia and normal serum erythropoietin levels despite of anemia. Serum iron levels were decreased in CKD rats compared with the controls. Of interest, intestinal expression of critical iron importers, such as duodenal cytochrome b (Dcyt-b) and divalent metal transporter 1 (DMT-1), was decreased in CKD rats compared with the controls. On the other hand, intestinal expression of ferroportin, an intestinal iron exporter, was not different in the control and CKD groups. Moreover, hepatic expression of hepcidin, a regulator of iron homeostasis, did not differ between the control and CKD groups. These results suggest that impaired intestinal expression of Dcyt-b and DMT-1 might be associated with the reduction of an iron uptake in CKD. Taken together, impaired these intestinal iron transporters may become a novel therapeutic target for cardio-renal anemia syndrome.

Sixty patients diagnosed with obstructive sleep apnea syndrome (OSAS) underwent uvulopalatopharyngoplasty (UPPP). The effects of surgery were studied based on endoscopic findings during drug-induced sleep and determination of the apnea-hypopnea index (AHI) before and after the operation. Changes in the form of the airway during sleep in the recumbent position were observed, and the role of upper airway endoscopy in the diagnosis and surgical treatment of OSAS was determined. The site of airway obstruction during sleep induced by i.v. injection of 10 mg of diazepam was classified into five types, and changes in AHI and the site of airway obstruction were compared before and after surgery. Changes in airway morphology during sleep in the supine and recumbent positions were also compared before surgery. The postoperative improvement rate was 74.4% for the soft palatal type of obstruction, 76.2% for the tonsillar type, 53.3% for the circumferential palatal type and 34.0% for the mixed type. Treatment produced excellent or good effects for the soft palatal and tonsillar types of obstruction. However, many patients with the circumferential palatal and mixed types of obstruction showed only some improvement or no change. Good airway morphology was maintained in the recumbent position by patients with the soft palatal type of obstruction. With the circumferential palatal and mixed types of obstruction, improvement can be expected from operations which include surgical treatment of the posterior pharyngeal wall or lateral funiculus, or with midline laser glossectomy. A good operative outcome can be predicted in patients showing improvement of apnea in the recumbent position preoperatively.

Experiments to determine the effect of furnishing an ample supply of sodium chloride on the toxemia of pyloric and intestinal obstruction are reported. A fall in chlorides is the first and seemingly most significant change to take place in the blood after pyloric and intestinal obstruction. The chloride is apparently utilized by the body as a protective measure against the primary toxic substance. Two dogs with pyloric obstruction were given 50 cc. of 10 per cent NaCl subcutaneously daily. One lived 3 days, the other 4. The blood showed little change, except a marked terminal rise in chlorides. Animals given a like amount of distilled water or 25 per cent glucose showed the changes typical of untreated animals. The obstruction of the pylorus was released in six dogs 48 to 72 hours after the initial operation. Two died within 24 hours after the second operation with a high non-protein nitrogen in the blood. Two survived but showed a high level of non-protein nitrogen in the blood and a high nitrogen excretion in the urine, low blood chlorides, and a marked alkalosis. One dog in such a state died on the 13th day from peritonitis, arising in a wound infection. The other showed a marked fall in non-protein nitrogen in the blood following the administration of 10 gm. of sodium chloride by mouth, but died following the intravenous injection of 25 per cent sodium chloride. Two animals were given 50 cc. of 10 per cent NaCl subcutaneously, at the time of the second operation. The blood rapidly returned to normal and complete recovery followed. Two dogs with the duodenum obstructed by section and inversion of the cut ends were treated with 10 per cent sodium chloride after the obstruction had existed for 48 hours and the characteristic blood changes had developed. The non-protein nitrogen returned to normal within 48 hours after treatment was begun. One dog died following a lateral anastomosis for relief of the obstruction. A second operation was not attempted in the other

In the management of short bowel syndrome (SBS), the benefits of treatment with growth hormone (GH), glutamine, and enteral nutrition (EN) on intestinal adaptation among children patients is still controversial. The aim of present study is to determine whether GH, glutamine, and EN have positive effect on intestinal adaptation in children with SBS. Sixteen children with SBS (small bowel remnant length, 56.75 ± 8.09 cm; mean ± SE) were treated with GH (0.05 mg/kg/d), glutamine (0.45 mg/kg/d), plus EN-enriched fiber diet for four weeks. After four weeks of treatment, patients were discharged home; GH was discontinued, but the EN with glutamine was continued. Repeated treatment was performed if there were lose weight, dysplasia, or severe diarrhea. All patients completed the treatment. Body weight, intestinal absorptive capacity, and plasma levels of proteins were significantly improved after complete treatment, without any major adverse effects. On follow-up, no death was reported. Treatment with GH, glutamine, and EN in early stage significantly improved intestinal adaptation in pediatric patients with SBS. Furthermore, the positive effect of the treatment does not seem to be sustained once GH discontinued until the residual intestinal adaptation reaches its maximum.

A one and half years male child presented with constipation with severe colicky abdominal pain, bilious vomiting & abdominal distension. He had history of recurrent bouts of constipation followed by gastroenteritis since birth for which he had taken symptomatic treatment & sometimes remained symptom free but he had no other significant history or associated condition. In laboratory investigations, barium enema study of large gut result simulates to Hirschsprung's disease but suction rectal biopsy revealed normal rectal tissue texture. So, consideration of diagnostic tools along with patient's general condition decision was taken for diagnostic laparotomy & peroperatively the child was diagnosed as a case of intestinal obstruction due to congenital colonic stenosis in the descending colon. After resection of stenotic segment and end to end anastomosis, histopathologycal examination of resected stenosed colon was done & it was finally proved as congenital stenosis in the descending colon. The post operative period of the patient was uneventful and he was discharged on 7th postoperative day & followed up upto 6 months. He had been found alright without any complain. Here we tried to high light that the congenital colonic stenosis as a rare, but might be a possible cause of partial/complete intestinal obstruction from newborn to older children in any part of the colon & that should kept in mind for avoiding diagnostic dilemma & proper management of patient.

Metabolic syndrome is an emerging problem in developed countries and presents itself as a potential threat worldwide. The role of diabetes, dyslipidaemia and hepatic steatosis as pivotal components of the metabolic syndrome is well known. However, their common persistent chronic inflammation and its potential cause still elude. This systematic review aims to present evidence of the mechanisms that link the intestinal microbioma, innate immunity and metabolic syndrome. A comprehensive research was made using PubMed database and 35 articles were selected. We found that metabolic syndrome is associated to increased levels of innate immunity receptors, namely, Toll-like receptors, both in intestine and systemically and its polymorphisms may change the risk of metabolic syndrome development. Microbioma dysbiosis is also present in metabolic syndrome, with lower prevalence of Bacteroidetes and increased prevalence of Firmicutes populations. The data suggest that the link between intestinal microbiota and Toll-like receptors can negatively endanger the metabolic homeostasis. Current evidence suggests that innate immunity and intestinal microbiota may be the hidden link in the metabolic syndrome development mechanisms. In the near future, this can be the key in the development of new prophylactic and therapeutic strategies to treat metabolic syndrome patients.

Sinusoidal obstruction syndrome (SOS) is a frequent, troubling, and potentially fatal complication of hematopoietic stem cell transplantation. Despite promising results with defibrotide (DF), no treatment has been established as standard. DF is a single-stranded polydeoxyribonucleotide, obtained from controlled depolymerization of porcine intestinal mucosal cells. It has antithrombotic, antiischemic, antiinflammatory, and thrombolytic properties without significant side effects. We retrospectively evaluated the charts of 80 consecutive patients, with 89 hematopoietic stem cell transplants for hematologic malignancies. The results of early initiation of DF treatment in 14 patients with SOS are presented in this study. Fourteen patients, 8 males and 6 females % median age 40.5 years (range, 16-46 years) were diagnosed to have SOS. Disease severity was classified as severe in 6 (42.85%), moderate in 4 (28.57%), and mild in 4 (28.57%) patients. We treated 14 patients with DF for a median of 21.5 days (range, 4-39 days). All 14 patients received DF after the diagnosis of SOS. Three patients with severe and all of the patients with mild to moderate SOS responded to treatment with complete resolution of SOS-related signs and symptoms. All patients responding to DF were alive at 100 days posttransplantation. There was no significant drug-related side effect among patients treated with DF. With an overall response rate of 78.56% and a 50% complete response rate in severe SOS cases and minimal side effects, we suggest that DF is the best available agent to treat SOS.

Longitudinal intestinal lengthening and tailoring (LILT) is a well-established surgical treatment for short bowel syndrome. It has been shown to enhance peristalsis, decrease bacterial overgrowth, and extend mucosal contact time for nutrients. We present the results of a long-term follow-up of patients who underwent LILT and define prognostic parameters for the survival of these patients. Between 1987 and 2006, 53 patients underwent LILT in our institution. The main diagnoses were gastroschisis, intestinal volvulus, intestinal atresias, and necrotizing enterocolitis. LILT was performed at a mean age of 24 months (range 4144 months). The follow-up time was 79.76 months (range 6234 months). After LILT, 41 of 53 patients survived, and 36 of 41 surviving patients were successfully weaned from parenteral nutrition (PN). In long-term follow-up 79% stayed free of PN. The overall survival rate was 77.36%. Weight gain occurred in 58% of the patients after LILT. The quality of life after LILT is on a high level, with most patients having normal physical strength and participating in normal social life and education. Prognostic factors for survival after LILT in short bowel syndrome are length of small intestine (0.06582 + 0.0131 x bowel cm), length of large bowel (P = 0.039), preoperative liver function, and successful weaning from PN within 18 months postoperatively (P = 0.0032). Patients undergoing LILT in short bowel syndrome have a high survival rate, weight gain, and a high quality of life. Autologous gastrointestinal reconstruction remains therefore the first choice in the treatment of patients with short bowel syndrome.

Lipoma is the most common benign mesenchymal neoplasm. About 16% of lipomas arise in the head and neck region, especially in the posterior neck. Large lipomas that originate from the retropharyngeal space may cause dyspnea, dysphagia, and snoring and occasionally may lead to obstructive sleep apnea syndrome (OSAS). Herein, we report a 45-year-old male patient with OSAS caused by a giant retropharyngeal lipoma with emphasis on CT findings. PMID:28912996

The goal of this study was to evaluate the influence of obstructive sleep apnoea on the severity and short-term prognosis of patients admitted for acute coronary syndrome. Obstructive sleep apnoea was defined as an apnoea-hypopnoea index (AHI) >15 h(-1). We evaluated the acute coronary syndrome severity (ejection fraction, Killip class, number of diseased vessels, and plasma peak troponin) and short-term prognosis (length of hospitalisation, complications and mortality). We included 213 patients with obstructive sleep apnoea (mean±sd AHI 30±14 h(-1), 61±10 years, 80% males) and 218 controls (AHI 6±4 h(-1), 57±12 years, 82% males). Patients with obstructive sleep apnoea exhibited a higher prevalence of systemic hypertension (55% versus 37%, p<0.001), higher body mass index (29±4 kg·m(-2) versus 26±4 kg·m(-2), p<0.001), and lower percentage of smokers (61% versus 71%, p=0.04). After adjusting for smoking, age, body mass index and hypertension, the plasma peak troponin levels were significantly elevated in the obstructive sleep apnoea group (831±908 ng·L(-1) versus 987±884 ng·L(-1), p=0.03) and higher AHI severity was associated with an increased number of diseased vessels (p=0.04). The mean length of stay in the coronary care unit was higher in the obstructive sleep apnoea group (p=0.03). This study indicates that obstructive sleep apnoea is related to an increase in the peak plasma troponin levels, number of diseased vessels, and length of stay in the coronary care unit.

Contemporary Surgery for Obstructive Sleep Apnea Syndrome

PubMed Central

2009-01-01

Surgical treatment of obstructive sleep apnea syndrome (OSAS) has been available in some form for greater than three decades. Early management for airway obstruction during sleep relied on tracheotomy which although life saving was not well accepted by patients. In the early eighties two new forms of treatment for OSAS were developed. Surgically a technique described as a uvulopalatopharyngoplasty (UPPP) was used to treat the retropalatal region for snoring and sleep apnea. Concurrently sleep medicine developed a nasal continuous positive airway pressure (CPAP) device to manage nocturnal airway obstruction. Both of these measures were used to expand and stabilize the pharyngeal airway space during sleep. The goal for each technique was to limit or alleviate OSAS. Almost 30 yr later these two treatment modalities continue to be the mainstay of contemporary treatment. As expected, CPAP device technology improved over time along with durable goods. Surgery followed suit and additional techniques were developed to treat soft and bony structures of the entire upper airway (nose, palate and tongue base). This review will only focus on the contemporary surgical methods that have demonstrated relatively consistent positive clinical outcomes. Not all surgical and medical treatment modalities are successful or even partially successful for every patient. Advances in the treatment of OSAS are hindered by the fact that the primary etiology is still unknown. However, both medicine and surgery continue to improve diagnostic and treatment methods. Methods of diagnosis as well as treatment regimens should always include both medical and surgical collaborations so the health and quality of life of our patients can best be served. PMID:19784401

Management of patients with obstructed defecation syndrome is still controversial. To analyze the efficacy of clinical, clinical treatment followed by biofeedback, and surgical treatment in patients with obstructed defecation, rectocele and multiple dysfunctions evaluated with echodefecography. The study included 103 females aged 26-84 years with obstructed defecation, grade-II/III rectocele and multiple dysfunctions on echodefecography. Patients were distributed into three treatment groups and constipation scores were assigned. Group I: 34 (33%) patients with significant improvement of symptoms through clinical management only. Group II: 14 (14%) with improvement through clinical treatment plus biofeedback. Group III: 55 (53%) referred to surgery due to treatment failure. Group I: 20 (59%) patients had grade-II rectocele, 14 (41%) grade-III. Obstructed defecation syndrome was associated with intussusception (41%), mucosal prolapse (41%), anismus (29%), enterocele (9%) or 2 dysfunctions (23%). The average constipation score decreased significantly from 11 to 5. Group II: 11 (79%) grade-II rectocele, 3 (21%) grade-III, associated with intussusception (7%), mucosal prolapse (43%), anismus (71%) or 2 dysfunctions (29%). There was significant decrease in constipation score from 13 to 6. Group III: 8 (15%) grade-II rectocele, 47 (85%) grade-III, associated with intussusception (42%), mucosal prolapse (40%) or 2 dysfunctions (32%). The constipation score remained unchanged despite clinical treatment and biofeedback. Twenty-three underwent surgery had a significantly decrease in constipation score from 12 to 4. The remaining 32 (31%) patients which 22 refused surgery, 6 had low anal pressure and 4 had slow transit. Approximately 50% of patients with obstructed defecation, rectocele and multiple dysfunctions presented a satisfactory response to clinical treatment and/or biofeedback. Surgical repair was mainly required in patients with grade-III rectocele whose constipation

Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a severe disease characterized by functional obstruction in the urinary and gastrointestinal tract. The molecular basis of this condition started to be defined recently, and the genes related to the syndrome (ACTG2-heterozygous variant in sporadic cases; and MYH11 (myosin heavy chain 11), LMOD1 (leiomodin 1) and MYLK (myosin light chain (MLC) kinase)-autosomal recessive inheritance), encode proteins involved in the smooth muscle contraction, supporting a myopathic basis for the disease. In the present article, we described a family with two affected siblings with MMIHS born to consanguineous parents and the molecular investigation performed to define the genetic etiology. Previous whole exome sequencing of the affected child and parents did not identify a candidate gene for the disease in this family, but now we present a reanalysis of the data that led to the identification of a homozygous deletion encompassing the last exon of MYL9 (myosin regulatory light chain 9) in the affected individual. MYL9 gene encodes a regulatory myosin MLC and the phosphorylation of this protein is a crucial step in the contraction process of smooth muscle cell. Despite the absence of human or animal phenotype related to MYL9, a cause-effect relationship between MYL9 and the MMIHS seems biologically plausible. The present study reveals a strong candidate gene for autosomal recessive forms of MMIHS, expanding the molecular basis of this disease and reinforces the myopathic basis of this condition.

Obstructive sleep apnea syndrome and fatty liver: Association or causal link?

Ahmed, Mohamed H; Byrne, Christopher D

2010-01-01

Obstructive sleep apnea (OSA) is a complex disorder that consists of upper airway obstruction, chronic intermittent hypoxia and sleep fragmentation. OSA is well known to be associated with hypoxia, insulin resistance and glucose intolerance, and these factors can occur in the presence or absence of obesity and metabolic syndrome. Although it is well established that insulin resistance, glucose intolerance and obesity occur frequently with non-alcoholic fatty liver disease (NAFLD), it is now becoming apparent that hypoxia might also be important in the development of NAFLD, and it is recognized that there is increased risk of NAFLD with OSA. This review discusses the association between OSA, NAFLD and cardiovascular disease, and describes the potential role of hypoxia in the development of NAFLD with OSA. PMID:20818807

Intestinal lymphangiectasia (IL) is a rare disease characterized by dilatation of intestinal lymphatics. It can be classified as primary or secondary according to the underlying etiology. The clinical presentations of IL are pitting edema, chylous ascites, pleural effusion, acute appendicitis, diarrhea, lymphocytopenia, malabsorption, and intestinal obstruction. The diagnosis is made by intestinal endoscopy and biopsies. Dietary modification is the mainstay in the management of IL with a variable response. Here we report 2 patients with IL in Bahrain who showed positive response to dietary modification. PMID:26837404

2011-01-01

Study Objective: Continuous positive airway pressure (CPAP) titration studies are commonly performed using a nasal mask but some patients may prefer a full-face or oronasal mask. There is little evidence regarding the equivalence of different mask interfaces used to initiate treatment. We hypothesized that oronasal breathing when using an oronasal mask increases upper airway collapsibility and that a higher pressure may be required to maintain airway patency. We also assessed patient preferences for the 2 mask interfaces. Design: Prospective, randomized, cross-over design with 2 consecutive CPAP titration nights. Setting: Accredited laboratory in a university hospital. Patients or Participants: Twenty-four treatment-naive subjects with obstructive sleep apnea syndrome and respiratory disturbance index of greater than 15 events per hour. Interventions: CPAP titration was performed using an auto-titrating machine with randomization to a nasal or oronasal mask, followed by a second titration night using the alternate mask style. Measurements and Results: There was no significant difference in the mean pressures determined between nasal and oronasal masks, although 43% of subjects had nasal-to-oronasal mask-pressure differences of 2 cm H2O or more. Residual respiratory events, arousals, and measured leak were all greater with the oronasal mask. Seventy-nine percent of subjects preferred the nasal mask. Conclusions: Patients with obstructive sleep apnea syndrome can generally switch between nasal and oronasal masks without changing machine pressure, although there are individual differences that may be clinically significant. Measured leak is greater with the oronasal mask. Most patients with obstructive sleep apnea syndrome prefer a nasal mask as the interface for initiation of CPAP.

A prospective, randomized, controlled study was performed to evaluate the effects of perioperative alanyl-glutamine-supplemented parenteral nutrition (PN) support on the immunologic function, intestinal permeability, and nutrition status of surgical patients with chronic radiation enteritis (CRE)-induced intestinal obstruction. Patients who received 0.4 g/kg/d alanyl-glutamine and isonitrogenous PN were assigned to an alanyl-glutamine-supplemented PN (Gln-PN) group and a control group, respectively. Serum levels of alanine aminotransferase and glutamine, body fat mass (FM), immunologic function, and intestinal permeability were measured before and after surgery. Serum glutamine levels of the Gln-PN group significantly exceeded that of the control group (P < .001; Gln-PN, baseline 460.7 ± 42.5 vs 523.3 ± 48.6 µmol/L on postoperative day 14 [POD14], P < .001; control, baseline 451.9 ± 44.0 vs 453.8 ± 42.3 µmol/L on POD14, P = .708). Lactulose/mannitol ratios of both groups decreased over time (Gln-PN, baseline 0.129 ± 0.0403 vs 0.024 ± 0.0107 on POD1 4; control, baseline 0.125 ± 0.0378 vs 0.044 ± 0.0126 on POD14, P < .001 in both groups). CD4/CD8-positive T-lymphocyte ratios significantly rose in both groups, with significant intergroup difference (P < .001; Gln-PN, baseline 1.36 ± 0.32 vs 1.82 ± 0.30 on POD14, P < .001; control, baseline 1.37 ± 0.25 vs 1.63 ± 0.31 on POD14, P < .001). In the Gln-PN group, FM increased from 3.68 ± 1.68 kg at baseline to 5.22 ± 1.42 kg on POD14 (P < .001). FM of control group increased from 3.84 ± 1.57 kg at baseline to 5.40 ± 1.54 kg on POD14 (P < .001). However, there were no significant intergroup differences (P = .614). Gln-PN significantly boosted the immune state and decreased the intestinal permeability of CRE patients. However, Gln-PN was not superior to standard PN in improving the nutrition state and intestinal motility of surgical patients with CRE-induced intestinal obstruction. © 2015 American Society

The absence or hipoplasia vaginal can turn out to be isolated, associated with ambiguous genitalia, or as anatomical variant in a syndrome of sewer. The fundamental aim in the creation of a new vagina is: to obtain a good aesthetic result, to fulfil functional criteria (elasticity, sensibility, physiological inclination) and to improve the quality of life of the patients avoiding the use of molds and minimizing the morbidity of the zones donors. In this work let's sense beforehand our experience in the accomplishment of neovaginas with intestine. We analyze the clinical record of 13 patients treated surgically in the last ten years. We differentiate two groups according to the age, the diagnosis and the type of surgery: a) the first group of 8 patients present syndrome of insensibility to the androgens (4), syndrome of Rokitansky (2), extrofia of sewer (1) and mixed gonadal disgenesia (1). This group of patients were controlled in the adolescence by an average of age of 19 years (11-35 years), they fulfilling a neovagina with sigma; b) the second group of 5 patients with sewer (3), extrofia of sewer (1) and congenital suprarrenal hiperplasia (1). This group was controlled prematurely by a middle ages of one year (4 months-3 years). The intestinal segment used as neovagina was sigma (2), ileon (2) and rectum (1), and was performed during the surgical correction of her congenital malformation. Two patients have presented intestinal obstruction in the postoperatory immediate one. Four patients have needed removal of a small vaginal prolapse, and three have needed vaginal transitory expansions for introit stenosis. The long-term evolution has been favorable with an excellent aesthetic aspect. Four patients recount sexual fully satisfactory relations. We believe that the neovagina with sigma is at present the best option in patients with absence or hipoplasia vaginal. The advantages are the possibility of precocious and one time correction, a neovagina of dimensions and

Recently, T cells were classified into two categories: intrathymic T cells (ITCs; thymus-derived T cells) and extrathymic T cells (ETCs). ETC, localized in the liver and intestinal intraepithelium (IE), play an important immunologic role in the suppressed condition of T-cell development in the thymus. Given the fact that complications of surgery in patients with obstructive jaundice are often related to immunosuppression in the gut-liver circulation, we attempted to investigate the changes in the proportion of ETCs in mice with obstructive jaundice. Three mice models were prepared ( n = 10 per group): sham group with simple laparotomy; ligation group with common bile duct ligation; deoxycholic acid (DCA) group with an oral intake of DCA as a model of the presence of bile salts in the gut lumen. In each model, total mononuclear cells (MNCs), ITCs in the thymus, and ETCs in the liver and IE were counted using monoclonal antibodies in conjunction with a two-color immunofluorescence test by flow cytometry. In the ligation group the number of MNCs was reduced in the thymus and IE, and only those in the IE recovered after oral intake of DCA. A decrease of ITCs in the thymus and the increase in ETCs in the liver and IE occurred simultaneously during the early phase of biliary obstruction. At day 7 after biliary obstruction, ETCs in the livers of the DCA and ligation groups decreased to nearly the level in the sham group. However, on day 7 the ETCs in the IE remained significantly higher in the DCA group than in the ligation group. These results suggested that ETCs can act in place of ITCs at an early phase of obstructive jaundice, and the presence of bile in the gut lumen may be associated with the consumption of ETCs in the IE, a reaction that may bring about improved immunoreactivity.

2010-01-01

Data on morphological and biomechanical remodeling are needed to understand the mechanisms behind intestinal obstruction. The effect of partial obstruction on mechanical properties with reference to the zero-stress state and on the histomorphological properties of the guinea pig small intestine was determined in this study. Partial obstruction and sham operation were surgically created in mid-jejunum of guinea pigs. The animals survived 2, 4, 7, and 14 days respectively. The age-matched guinea pigs that were not operated served as normal controls. The segment proximal to the obstruction site was used for histological analysis, no-load state and zero-stress state data, and distension test. The segment for distension was immersed in an organ bath and inflated to 10 cmH20. The outer diameter change during the inflation was monitored using a microscope with CCD camera. Circumferential stresses and strains were computed from the diameter, pressure and the zero-stress state data. The opening angle and absolute value of residual strain decreased (P<0.01 and P<0.001) whereas the wall thickness, wall cross-sectional area, and the wall stiffness increased after 7 days obstruction (P<0.05, P<0.01). Histologically, the muscle and submucosa layers, especially the circumferential muscle layer increased in thickness after obstruction. The opening angle and residual strain mainly depended on the thickness of the muscle layer whereas the wall stiffness mainly depended on the thickness of the submucosa layer. In conclusion, the histomorphological and biomechanical properties of small intestine (referenced for the first time to the zero-stress state) remodel proximal to the obstruction site in a time-dependent manner.

Obstructive Sleep Apnea Syndrome (OSA) is a multifactorial disease that highly alters a persons quality of life. It is characterized by the repeated interruption of breathing during sleep, due to an obstruction or the collapse of the upper airways. Since it is a multifactorial etiological disorder, it requires a thorough diagnosis and treatment with an interdisciplinary team, which comprises several professionals such as a surgical dentist, phonoaudiologist, otorhinolaryngologist, sleep doctor, neurologist and physiotherapist. The diagnosis and the degree of severity of the syndrome is determined through a polysomnography examination. After that, the best form of treatment is devised depending on the gravity of the case. In cases of moderate to severe apnea, invasive treatment through surgical procedures such as maxillomandibular advancement remains the preferred option as it increases the posterior air space, reducing and/or eliminating the obstruction. Thus, improving the patients respiratory function and, consequently, his quality of life as it is shown in the clinical case at hand. In which the male patient, facial pattern type I, 41 years of age, diagnosed with moderate OSA (Apnea-Hypopnea Index - AHI of 23.19), decided to have a surgical treatment instead of a conservative one, resulting in the cure of apnea (AHI of 0.3).

To evaluate the usefulness of serum biochemical variables and scintigraphic study results for differentiating between dogs and cats with complete extrahepatic biliary obstruction (EHO) and those with partial EHO or patent bile ducts. Retrospective case series. 17 dogs and 1 cat. Animals that underwent hepatobiliary scintigraphy and had either surgical or postmortem confirmation of the degree of bile duct patency were included. Scintigraphic images were evaluated and biliary tracts were classified as patent, partially obstructed but patent, or obstructed. Surgery or postmortem examination was considered the gold standard for diagnosis, and compared with those findings, sensitivity and specificity of scintigraphy were calculated. With absence of radioactivity in the intestinal tract as the diagnostic criterion for EHO, the sensitivity and specificity of scintigraphic diagnosis were both 83% when final images were acquired at 19 to 24 hours, compared with 100% and 33%, respectively, when 180 minutes was used as the cutoff time. Animals with partial biliary obstruction had less intestinal radioactivity that arrived later than that observed in animals with patent biliary tracts. Animals in which intestinal radioactivity has not been observed after the standard 3 to 4 hours should undergo additional scintigraphic imaging. Findings in animals with partial biliary obstruction include delayed arrival of radioactivity and less radioactivity in the intestine. Distinguishing between complete and partial biliary tract obstruction is important because animals with partial obstruction may respond favorably to medical management and should not be given an erroneous diagnosis of complete obstruction.

We report a case of a 64-year-old lady who developed clinical features of Wernicke-Korsakoff syndrome following a laparotomy for small bowel obstruction. Following the operation she developed paralytic ileus and required total parenteral nutrition for one month. A suspected history of average 40 units of weekly alcohol consumption prior to the operation could not be confirmed and the patient did not show any sign of alcohol dependence. Within a few months of treatment with a daily oral dose of thiamine 200 mgs supplemented by multivitamins the patient showed subjective evidence of improvement in confusion, confabulation, and anterograde amnesia, although objective tests showed residual deficits in many areas of cognitive functioning, including immediate and delayed recall of verbal and non-verbal materials, planning and switching of attention.

We report a case of sinusoidal obstruction syndrome, a typical and life-threatening complication after allogeneic stem-cell transplantation, successfully treated with defibrotide despite massive multiple organ failure. A 64-year-old Caucasian woman underwent allogeneic peripheral blood stem-cell transplantation from her human leukocyte antigen-identical sister against aggressive lymphoplasmocytoid immunocytoma. Seven days later, the patient developed severe sinusoidal obstruction syndrome according to the modified Seattle criteria. We initiated treatment with defibrotide. Despite early treatment, multiple organ failure with kidney failure requiring dialysis and ventilator-dependent lung failure aggravated the clinical course. Furthermore, central nervous dysfunction occurred as well as transfusion refractory thrombocytopenia. As highlighted in our report, defibrotide is the most promising drug in the treatment of the formerly, almost lethal, severe sinusoidal obstruction syndrome to date. This is demonstrated very clearly in our patient. She improved completely, even after renal, cerebral and respiratory failure.

Obstructive sleep apnea syndrome and upper airway inflammation.

PubMed

Inancli, Hasan M; Enoz, Murat

2010-01-01

Obstructive sleep apnea syndrome (OSAS) is associated with inflammatory processes and elevated plasma cytokines. Inflammatory processes associated with OSAS may also act as potential mediators of cardiovascular morbidity in these patients. OSAS is associated with elevated levels of C reactive protein (CRP), as a marker of inflammation and cardiovascular risk. At the inflammatory point of view, the levels of TNF-alpha, IL-6, hsCRP, adhesion molecules, monocyte chemo attractant protein-1 and resist in were markedly and significantly elevated in patients with sleep apnea than those in normal control subjects. We reviewed several recent patents and literature in English about OSAS and upper airway inflammation relation since 1966 from the Medline database.

To evaluate the results of combined multilevel surgery with transoral robotic surgery (TORS) in patients with obstructive sleep apnea/hypopnea syndrome for multilevel upper airway obstruction. Subjects who underwent combined sleep surgery via TORS were evaluated. The drug-induced sleep endoscopy was used in diagnosing the presence of level-specific upper airway collapse and to detect the type of surgery. Pre- and postoperative Apnea-hypopnea index, Epworth sleepiness scale lowest oxygen saturation, total operation time, robotic set-up time and robotic surgery time, blood loss value, and complications were recorded. Twenty five subjects were identified. All subjects underwent base of tongue (BOT) + epiglottoplasty. The tracheotomy was not performed for any patient. Overall, 72% of patients met the criteria for cure, 8% met the criteria for cure, and 20% of patients met the criteria for failure. There was a significant decrease between preoperative and postoperative Apnea-hypopnea index scores (28.7 ± 17.8 SD versus 9.4 ± 12.4, P = 0.000) and Epworth sleepiness scale scores (13.5 ± 2.8 versus 3.4 ± 1.6, P = 0.000). There was a significant increase between preoperative and postoperative ED SPO2 levels (80.7 ± 7.6 versus 82.6 ± 18.1, P = 0.001). TORS BOT, epiglottoplasty, and multilevel procedures in patients with obstructive sleep apnea/hypopnea syndrome can be regarded as feasible, safe, and effective technique.

The obstructed defecation syndrome is a frequent condition in the female population. Rectocele and rectal intussusception may cause symptoms of obstructed defecation. The aim of this study is to carry out an economic cost-revenue analysis comparing the rectocele and the rectal intussusception surgical techniques using a double-transanal, circular stapler (Stapled Trans-Anal Rectal Resection - STARR) with other techniques used to repair the same defects. The analysis involved the systematic calculation of the costs incurred during hospitalisation. The revenue estimate was obtained according to the rate quantification of the Diagnosis Related Group (DRG) associated with each hospitalisation. Our analysis confirmed that the global expenditure for the STARR technique amounts to 3,579.09 Euro as against 5,401.15 Euro for rectocele abdominal repair and 3,469.32 Euro for perineal repair. The intussusception repair cost according to Delorme's procedure amounts to 5,877.41Euro as against 3,579.09 Euro for the STARR technique. The revenue analysis revealed a substantial gain for the Health Authority as regards the treatment of rectocele and rectal intussusception for obstructed defecation syndrome. The highest revenue, 6,168. 52 Euro, was obtained with intussusception repair with STARR as compared to Delorme's procedure which presented revenue amounting to 2,359.04. Lower revenues are recorded if the STARR technique is intended for rectocele repair; in this case the revenue amounts to 1,778.12 Euro as against 869.67 Euro and 1,887.89 Euro for abdominal and perineal repair, respectively.

The case of a 50 year old male with the Fiessinger-Leroy-Reiter syndrome, ankylosing spondylitis and generalised pustular psoriasis is reported. This condition wax complicated by non-obstructive cardiomyopathy, congestive cardiac failure and first-degree atrioventricular block, the site of which was localised by electrophysiological studies (nodal block with an infrahisian conduction defect). After failure of several therapeutic regimes, a spectacular improvement was obtained with Methotrexate associated with a diuretic; the signs of heart failure regressed and the cardiomyopathy stablised. A parallel improvement was seen in the skin, cardiac and articular lesions and has been maintained with an 18 months follow-up. Left ventricular performance was studied by echocardiography. The mechanism of the beneficial effect of Methotrexate is unclear; this therapeutic trial is to be extended to include other cases of primary cardiomyopathy without obstruction.

In the present study, we reconstructed upper airway and soft palate models of 3 obstructive sleep apnea—hypopnea syndrome (OSAHS) patients with nasal obstruction. The airflow distribution and movement of the soft palate before and after surgery were described by a numerical simulation method. The curative effect of nasal surgery was evaluated for the three patients with OSAHS. The degree of nasal obstruction in the 3 patients was improved after surgery. For 2 patients with mild OSAHS, the upper airway resistance and soft palate displacement were reduced after surgery. These changes contributed to the mitigation of respiratory airflow limitation. For the patient with severe OSAHS, the upper airway resistance and soft palate displacement increased after surgery, which aggravated the airway obstruction. The efficacy of nasal surgery for patients with OSAHS is determined by the degree of improvement in nasal obstruction and whether the effects on the pharynx are beneficial. Numerical simulation results are consistent with the polysomnogram (PSG) test results, chief complaints, and clinical findings, and can indirectly reflect the degree of nasal patency and improvement of snoring symptoms, and further, provide a theoretical basis to solve relevant clinical problems.

Is obstructive sleep apnoea syndrome really one of the causes of secondary polycythaemia?

PubMed

Solmaz, Soner; Duksal, Faysal; Ganidağlı, Sencer

2015-03-01

It is widely believed that sleep apnoea syndrome leads to polycythaemia, but the evidence is largely anecdotal. We believe that polycythaemia is not commonly seen in patients with sleep apnoea syndrome. Therefore, we aimed to determine the relationship between polycythaemia and sleep apnoea syndrome. The study included 335 patients diagnosed with obstructive sleep apnoea (OSA) syndrome, all of whom underwent standard nocturnal polysomnography. There were no significant differences in haemoglobin levels or haematocrit (P > 0.05) between the OSA groups in all patients. Of the 335 patients, only 1 male patient with severe OSA (0.3%) had clinically significant polycythaemia. According to regression analysis, there was a weak linear correlation between haemoglobin levels and lowest oxygen saturation levels in female patients (r = -0.242, P = 0.021). We think that OSA is very rarely the reason for secondary polycythaemia.

A Pro-Inflammatory Role for Nuclear Factor Kappa B in Childhood Obstructive Sleep Apnea Syndrome

PubMed Central

Israel, Lee P.; Benharoch, Daniel; Gopas, Jacob; Goldbart, Aviv D.

2013-01-01

Study Objectives: Childhood obstructive sleep apnea syndrome (OSAS) is associated with an elevation of inflammatory markers such as C-reactive protein (CRP) that correlates with specific morbidities and subsides following intervention. In adults, OSAS is associated with activation of the transcription factor nuclear factor kappa B (NF-kB). We explored the mechanisms underlying NF-kB activation, based on the hypothesis that specific NF-kB signaling is activated in children with OSAS. Design: Adenoid and tonsillar tissues from children with OSAS and matched controls were immunostained against NF-kB classical (p65 and p50) and alternative (RelB and p52) pathway subunits, and NF-kB-dependent cytokines: interleukin (IL)- 1α, IL-1β, tumor necrosis factor-α, and IL-8). Serum CRP levels were measured in all subjects. NF-kB induction was evaluated by a luciferase-NF-kB reporter assay in L428 cells constitutively expressing NF-kB and in Jurkat cells with inducible NF-kB expression. p65 translocation to the nucleus, reflecting NF-kB activation, was measured in cells expressing fluorescent NF-kB-p65-GFP (green fluorescent protein). Setting: Sleep research laboratory. Patients or Participants: Twenty-five children with OSAS and 24 without OSAS. Interventions: N/A. Measurements and Results: Higher expression of IL-1α and classical NF-kB subunits p65 and p50 was observed in adenoids and tonsils of children with OSAS. Patient serum induced NF-kB activity, as measured by a luciferase-NF-kB reporter assay and by induction of p65 nuclear translocation in cells permanently transfected with GFP-p65 plasmid. IL-1β showed increased epithelial expression in OSAS tissues. Conclusions: Nuclear factor kappa B is locally and systemically activated in children with obstructive sleep apnea syndrome. This observation may motivate the search for new anti-inflammatory strategies for controlling nuclear factor kappa B activation in obstructive sleep apnea syndrome. Citation: Israel LP

Intestinal Volvulus in Idiopathic Steatorrhea

Warner, H. A.; Kinnear, D. G.; Cameron, D. G.

1963-01-01

Volvulus of the intestine has recently been observed in three patients with idiopathic steatorrhea in relapse. Two patients gave a history of intermittent abdominal pain, distension and obstipation. Radiographic studies during these attacks revealed obstruction at the level of the sigmoid colon. Reduction under proctoscopic control was achieved in one instance, spontaneous resolution occurring in the other. The third patient presented as a surgical emergency and underwent operative reduction of a small intestinal volvulus. Persistence of diarrhea and weight loss postoperatively led to further investigation and a diagnosis of idiopathic steatorrhea. In all cases, treatment resulted in clinical remission with a coincident disappearance of obstructive intestinal symptoms. The pathogenesis of volvulus in sprue is poorly understood. Atonicity and dilatation of the bowel and stretching of the mesentery likely represent important factors. The symptoms of recurrent abdominal pain and distension in idiopathic steatorrhea necessitate an increased awareness of intestinal volvulus as a complication of this disease.

Waugh's Syndrome: Blessing in Disguise.

PubMed

Behera, Chinmaya Ranjan; Mohanty, Subrat K

Waugh's syndrome is the association between intestinal malrotion and intussusceptions. We report a case of Waugh's syndrome in a one year old child who presented to us with acute bowel obstruction and bleeding per rectum. Due to malrotation, there was easy prolapsing of ileocolic region into the nonfixed ascending colon and the intussusceptum advanced into the descending colon and rectum without compromising vascularity of the bowel. In most of the cases the intussusceptum advancing into the rectum is associated with bowel gangrene even when ceacum is mobile. But in our case, mobile caecum with malrotation proved to be blessing in disguise in preventing such a complication. A Meckel's diverticulum was also an incidental finding in this case. Waugh's syndrome is missed in cases of close reduction of intussusception and may be a reason for recurrence. Though a rare entity, the probability of Waugh's syndrome should be kept in mind during surgery, during hydrostatic reduction of intussusceptions, and in case of recurrent ileocolic intussusceptions.

Twin to twin transfusion syndrome (TTTS) is caused by aberrant vascular connections between infant twins and results in high morbidity and mortality in the perinatal period. In donor infants with TTTS and symptoms of intestinal obstruction, small-bowel lesions have been reported in most cases. We report on a 33(+6) gestational wk donor infant with TTTS who had intermittent obstructive episodes, including delayed meconium passage and colonic dilatation on abdominal X-ray. The diagnosis of Hirschsprung's disease was based on a lateral pelvic film with a reversed rectosigmoid ratio. A subsequent barium colon study and rectal suction biopsy indicated a short segment aganglionosis of the colon.

This is a case of a 33 weeks pregnant woman, presented 2 years after laparoscopic Roux-en-Y gastric bypass, with abdominal pain for 2 days. A laparoscopic cholecystectomy was performed 1 day earlier in another hospital, without improving the pain. She presented at our hospital with acute abdominal pain and clinical signs of intestinal obstruction, undergoing an exploratory laparotomy that revealed a volvulus and necrosis of the jejunum from the gastroenteroanastomosis through the lateral enteroenterostomy, which was resected with the reconstruction of the Roux-en-Y limb performed at the same operation. Patient and neonate presented with improvement after surgery and the patient was discharged on postoperative day 15. Internal hernias after bariatric surgery have been reported as the cause of acute abdomen problems during pregnancy, which may progress to necrosis and perforation. The delay of surgical intervention could have brought a tragic outcome for mother and neonate.

Neonatal short bowel syndrome following massive gut resection is associated with malabsorption of nutrients. The intestinotrophic factor glucagon-like peptide 2 (GLP-2) improves gut function in adult patients with short bowel syndrome, but its effect in pediatric patients remains unknown. Our objective was to test the efficacy of the long-acting synthetic human GLP-2 analogue, teduglutide (ALX-0600), in a neonatal piglet jejunostomy model. Two-day-old pigs were subjected to resection of 50% of the small intestine (distal part), and the remnant intestine was exteriorized on the abdominal wall as a jejunostomy. All pigs were given total parenteral nutrition for 7 days and a single daily injection of the following doses of teduglutide: 0.01 (n = 6), 0.02 (n = 6), 0.1 (n = 5), or 0.2 mg · kg · day (n = 6), and compared with placebo (n = 9). Body weight increment was similar for all 4 teduglutide groups but higher than placebo (P < 0.05). There was a dose-dependent increase in weight per length of the remnant intestine (P < 0.01) and fractional protein synthesis rate in the intestine was increased in the 0.2 mg · kg · day group versus placebo (P < 0.001); however, functional and structural endpoints including activity of digestive enzymes, absorption of enteral nutrients, and immunohistochemistry (Ki67, villin, FABP2, ChgA, and GLP-2R) were not affected by the treatment. Teduglutide induces trophicity on the remnant intestine but has limited acute effects on functional endpoints. Significant effects of teduglutide on gut function may require a longer adaptation period and/or a more frequent administration of the peptide. In perspective, GLP-2 or its analogues may be relevant to improve intestinal adaptation in pediatric patients with short bowel syndrome.

Obstructive sleep apnea syndrome (OSAS) has been reported among children aged 3-6 years. Adenotonsillar hypertrophy is the most common cause of OSAS. The upper airway obstruction results in repeated obstructive apneas and hypopneas, associated with oxygen desaturations and sleep fragmentation. OSAS in children is associated with higher respiratory morbidity as well as significant clinical consequences, mainly neurocognitive and behavioral problems, impaired growth and cardiac dysfunction. The objectives of the present study were to determine the clinical and sleep characteristics of OSAS in children younger than 2 years, and to evaluate morbidity and health care utilization of infants with OSAS. This retrospective study included 35 children younger than 2 years of age, referred for polysomnography because of suspected OSAS. The controL group included healthy children, matched by age, gender and pediatrician. A total of 33 infants were diagnosed with OSAS. Mean apnea/hypopnea index [AHI) was 18.7 +/- 18.1 events/ hour [range 1.3-90.2]. In 10 infants a pattern of intermittent hypoxemia was observed. Infants with OSAS demonstrated a higher number of primary care clinic visits (20.8 +/- 14 vs. 12.1 +/- 6.6, P < 0.02). A higher percentage of children with OSAS visited the emergency room (60.6% vs. 32.2%, P < 0.03), and was hospitalized (36.3% vs. 12.9%, P < 0.03). Duration of hospitalization was also higher in the OSAS group [23.2 +/- 14.1% vs. 3 +/- 2.1%, P < 0.05). The number of drug prescriptions was higher among the study group [25.9 +/- 21.8% vs. 13.6 +/- 10.1, P < 0.03). Thirteen patients underwent adenoidectomy with or without tonsillectomy, resulting in improvement of AHI, decreasing from 26.4 +/- 24 before to 3.6 +/- 4.5 events per hour after surgery (p < 0.01). OSAS can be found in infants younger than 2 years of age. OSAS at this young age is characterized by a higher morbidity in comparison to healthy children. Early diagnosis and treatment may prevent

Small bowel volvulus is a rare cause of intestinal obstruction in adult patients. This disease is more common in children and its aetiology and management is different to that in adults. A 30 year-old male with sarcoidosis presents with acute abdomen and clinical data of intestinal obstruction. Small bowel volvulus is diagnosed by a contrast abdominal tomography and an exploratory laparotomy is performed with devolvulation and no intestinal resection. In the days following surgery, he developed a recurrent small bowel volvulus, which was again managed with surgery, but without intestinal resection. Medical treatment for sarcoidosis was started, and with his clinical progress being satisfactory,he was discharged to home. Making an early and correct diagnosis of small bowel volvulus prevents large intestinal resections. Many surgical procedures have been described with a high rate of complications. Therefore, conservative surgical management (no intestinal resection) is recommended as the best treatment with the lowest morbidity and mortality rate.

The aim of the study was to assess correlations of subgingival biofilm and intestinal microbiota in patients with chronic periodontal disease (CPD) and metabolic syndrome (MS). The study included 80 patients divided in 2 groups: 40 healthy individuals with no signs of periodontal disease and 40 patients with CPD and MS. Oral and intestinal microbial consortia compositions were revealed using deep sequencing libraries of 16S rDNA. The study showed than the qualitative composition of the intestinal microbiome in patients with CPD differ significantly from the microbiome of controls. Real-time PCR of subgingival microflora in CPD patients revealed high content of P. gingivalis, T. forsythia and T. denticola, while in intestinal microbiome dominated representatives of Enterobacteriaceae and Eubacteriaceae families with signs of intestinal dysbiosis mostly associated with the decrease of protective species.

To investigate the neutrophil-to-lymphocyte ratio and sleep apnoea severity relationship. Patients (n = 178) were assigned to five groups according to apnoea-hypopnea indices and continuous positive airway pressure use. White blood cell, neutrophil, lymphocyte and neutrophil-to-lymphocyte ratio values were compared for each group. The neutrophil-to-lymphocyte ratio values of severe obstructive sleep apnoea syndrome patients (group 4) were significantly higher than those of: control patients (group 1), mild obstructive sleep apnoea syndrome patients (group 2) and patients treated with continuous positive airway pressure (group 5) (p = 0.008, p = 0.008 and p = 0.003). Minimum oxygen saturation values of group 4 were significantly lower than those of groups 1, 2 and 5 (p = 0.0005, p = 0.011 and p = 0.001). There was a positive correlation between apnoea-hypopnea index and neutrophil-to-lymphocyte ratio (r = 0.758, p = 0.034), and a negative correlation between apnoea-hypopnea index and minimum oxygen saturation (r = -0.179, p = 0.012). Neutrophil-to-lymphocyte ratio may be used to determine disease severity, complementing polysomnography.

Patients with severe tracheal obstruction in Morquio A syndrome are at risk of dying of sleep apnea and related complications. Tracheal obstruction also leads to life-threatening complications during anesthesia as a result of the difficulty in managing the upper airway due to factors inherent to the Morquio A syndrome, compounded by the difficulty in intubating the trachea. A detailed description of the obstructive pathology of the trachea is not available in the literature probably due to lack of a homogenous group of Morquio A patients to study at any one particular center. We present a series of cases with significant tracheal obstruction who were unrecognized due to the difficulty in interpreting tracheal narrowing airway symptoms. Our goal is to provide the guidelines in the management of these patients that allow earlier recognition and intervention of tracheal obstruction. Sagittal MRI images of the cervical spine of 28 Morquio A patients (12 ± 8.14 years) showed that19/28 (67.9%) patients had at least 25% tracheal narrowing and that narrowing worsened with age (all 8 patients over 15 years had greater than 50% narrowing). Eight out of 28 patients were categorized as severe (>75%) tracheal narrowing when images were evaluated in neutral head and neck position. Of the 19 patients with tracheal narrowing, compression by the tortuous brachiocephalic artery was the most common cause (n = 15). Evidence of such tracheal narrowing was evident as early as at 2 years of age. The etiology of tracheal impingement by the brachiocephalic artery in Morquio A appears to be due to a combination of the narrow thoracic inlet crowding structures and the disproportionate growth of trachea and brachiocephalic artery in relationship to the chest cavity leading to tracheal tortuosity. In conclusion, tracheal narrowing, often due to impression from the crossing tortuous brachiocephalic artery, increases with age in Morquio A patients. Greater attention to the trachea is needed

Intestinal malrotation is a rare cause of bowel obstruction in adults and it could create a perplexing situation for surgeons not familiar with this pediatric pathology. Symptomatic patients present either acutely with bowel obstruction and intestinal ischemia with a midgut or cecal volvolus, or chronically with vague abdominal pain. Several modalities can be used to describe the intestinal abnormality such as barium X-ray, computer tomography scans, angiography and sometimes also the explorative laparotomy. The authors report on a case 62 years-old women presented to Emergency Center for plurime episodies of biliar emesis and diffuse abdominal pain in the last 5 days and treated for bowel obstruction secondary to a midgut volvolus in anomaly of fetal intestinal rotation.

SBS patients develop clinical mal-absorption and dehydration relative to the reduction of absorptive area, acceleration of gastrointestinal transit time and modifications of the gastrointestinal intra-luminal environment. As a consequence of severe mal-absorption, patients require parenteral nutrition (PN). In adults, the overall adaptation following intestinal resection includes spontaneous and complex compensatory processes such as hyperphagia, mucosal remodeling of the remaining part of the intestine and major modifications of the microbiota. SBS patients, with colon in continuity, harbor a specific fecal microbiota that we called “lactobiota” because it is enriched in the Lactobacillus/Leuconostoc group and depleted in anaerobic micro-organisms (especially Clostridium and Bacteroides). In some patients, the lactobiota-driven fermentative activities lead to an accumulation of fecal d/l-lactates and an increased risk of d-encephalopathy. Better knowledge of clinical parameters and lactobiota characteristics has made it possible to stratify patients and define group at risk for d-encephalopathy crises. PMID:27681910

Some patients previously diagnosed with irritable bowel syndrome (IBS) may develop microscopic colitis or small intestinal bacterial overgrowth (SIBO). To estimate the prevalence of microscopic colitis and SIBO in patients with IBS, to evaluate the symptoms and the efficacy of treatment. We examined patients with IBS admitted in our clinic during a three-year period. We identified patients with microscopic colitis by performing total colonoscopy with multiple biopsies from normal intestinal mucosa and those with SIBO by performing a H2-breath test with glucose. We compared the symptoms and the effectiveness of the treatment. Out of the 132 patients initially diagnosed with IBS 3% (n=4) had microscopic colitis and 43.9% (n=58) had SIBO. Diarrhea was the main symptom in patients with microscopic colitis and SIBO (p=0.041), while abdominal pain, abdominal bloating and flatulence were prominent in IBS patients (p=0.042; p=0.039; p=0.048). Specific treatment with rifaximin in SIBO patients negativated H2-breath test in 70.9% cases. Patients suspected to have irritable bowel syndrome should be evaluated for microscopic colitis and SIBO. The proper diagnosis and the specific treatment may cure some difficult cases of the so called "irritable bowel syndrome".

Continuous positive airway pressure (CPAP) titration studies are commonly performed using a nasal mask but some patients may prefer a full-face or oronasal mask. There is little evidence regarding the equivalence of different mask interfaces used to initiate treatment. We hypothesized that oronasal breathing when using an oronasal mask increases upper airway collapsibility and that a higher pressure may be required to maintain airway patency. We also assessed patient preferences for the 2 mask interfaces. Prospective, randomized, cross-over design with 2 consecutive CPAP titration nights. Accredited laboratory in a university hospital. Twenty-four treatment-naive subjects with obstructive sleep apnea syndrome and respiratory disturbance index of greater than 15 events per hour. CPAP titration was performed using an auto-titrating machine with randomization to a nasal or oronasal mask, followed by a second titration night using the alternate mask style. There was no significant difference in the mean pressures determined between nasal and oronasal masks, although 43% of subjects had nasal-to-oronasal mask-pressure differences of 2 cm H(2)O or more. Residual respiratory events, arousals, and measured leak were all greater with the oronasal mask. Seventy-nine percent of subjects preferred the nasal mask. Patients with obstructive sleep apnea syndrome can generally switch between nasal and oronasal masks without changing machine pressure, although there are individual differences that may be clinically significant. Measured leak is greater with the oronasal mask. Most patients with obstructive sleep apnea syndrome prefer a nasal mask as the interface for initiation of CPAP.

The aim of the present study was to evaluate the diagnostic accuracy of magnetic resonance (MR) defecography and compare it with videodefecography in the evaluation of obstructed defecation syndrome. This was a prospective cohort test accuracy study conducted at one major tertiary referral center on patients with a diagnosis of obstructed defecation syndrome who were referred to the colorectal surgery clinic in a consecutive series from 2009 to 2012. All patients underwent a clinical examination, videodefecography, and MR defecography in the supine position. We analyzed diagnostic accuracy for MR defecography and performed an agreement analysis using Cohen's kappa index (κ) for each diagnostic imaging examination performed with videodefecography and MR defecography. We included 40 patients with Rome III diagnostic criteria of obstructed defecation syndrome. The degree of agreement between the two tests was as follows: almost perfect for anismus (κ = 0.88) and rectal prolapse (κ = 0.83), substantial for enterocele (κ = 0.80) and rectocele grade III (κ = 0.65), moderate for intussusception (κ = 0.50) and rectocele grade II (κ = 0.49), and slight for rectocele grade I (κ = 0.30) and excessive perineal descent (κ = 0.22). Eighteen cystoceles and 11 colpoceles were diagnosed only by MR defecography. Most patients (54%) stated that videodefecography was the more uncomfortable test. MR defecography could become the imaging test of choice for evaluating obstructed defecation syndrome.

To assess relationships between obstructive lung diseases, respiratory symptoms, and comorbidities by gender. Data from 12 594 adult respondents to the 2012 South Carolina Behavioral Risk Factor Surveillance System telephone survey were used. Five categories of chronic obstructive airway disease (OAD) were defined: former asthma only, current asthma only, chronic obstructive pulmonary disease (COPD) only, asthma-COPD overlap syndrome (ACOS), and none. Associations of these categories with respiratory symptoms (frequent productive cough, shortness of breath, and impaired physical activities due to breathing problems), overall health, and comorbidities were assessed using multivariable logistic regression for men and women. Overall, 16.2% of men and 18.7% of women reported a physician diagnosis of COPD and/or asthma. Former asthma only was higher among men than women (4.9% vs. 3.2%, t-test p = 0.008). Current asthma only was more prevalent among women than men (7.2% vs. 4.7%, p < 0.001), as was ACOS (4.0% vs. 2.2%, p < 0.001). Having COPD only did not differ between women (4.3%) and men (4.4%). Adults with ACOS were most likely to report the 3 respiratory symptoms. COPD only and ACOS were associated with higher likelihoods of poor health and most comorbidities for men and women. Current asthma only was also associated with these outcomes among women, but not among men. In this large population-based sample, women were more likely than men to report ACOS and current asthma, but not COPD alone. Gender differences were evident between the OAD groups in sociodemographic characteristics, respiratory symptoms, and comorbidities, as well as overall health.

Intestinal ischemia-reperfusion injury in horses: pathogenesis and therapeutics.

PubMed

Wong, David M; Moore, Rustin M; Brockus, Charles W

2012-08-01

This article discusses the potential role of oxidative injury to the intestinal tract of horses and the therapeutic approaches that have been investigated to decrease cellular damage secondary to ischemia-reperfusion (IR) injury. Equine colic is a major concern for horse owners and veterinary practitioners. Strangulating and obstructive lesions of the small and large intestines commonly require intervention in patients via exploratory celiotomy. However, the application of information from experimentally induced IR injury in horses to clinical cases of naturally occurring equine colic is not clear. Thus, while the exact mechanisms and clinical significance of intestinal IR are being defined and may be matters of academic debate, a review of the available information may provide knowledge of potential underlying pathophysiologic mechanisms contributing to intestinal injury in equine colic. This information may allow clinicians to offer additional therapeutic strategies for horses with strangulating obstruction of the small or large intestine. Further clinical study of the therapeutic options for horses with naturally occurring disease is warranted.

Giant pseudomeningocele causing urinary obstruction in a patient with Marfan syndrome.

Defective collagen biosynthesis in Marfan syndrome predisposes to dural defects such as dural ectasia, meningocele, and pseudomeningocele; thus, an increased index of suspicion for these conditions should be present in the clinical setting of Marfan syndrome. The authors describe a young woman with Marfan syndrome who was being treated with anticoagulants for a prosthetic heart valve and who presented with a spontaneous retroperitoneal hemorrhage requiring surgical evacuation. No CSF leak was encountered at surgery, but she developed progressively more severe positional headaches over the following year. She then experienced the sudden onset of acute urinary obstruction, at which time CT revealed a 17 × 15 × 13-cm presacral pseudomeningocele communicating with the thecal sac through a sacral bone defect. An anterior surgical approach was used for drainage of the pseudomeningocele as well as for primary closure of the dural defect with a bovine pericardial patch and autologous subcutaneous fat graft. After a short period of lumbar subarachnoid drainage of the CSF, the patient was able to resume normal activity without recurrent symptoms. To the authors' knowledge, such a pseudomeningocele in a patient with Marfan syndrome has been reported only twice, and this case features the largest pseudomeningocele to date. They also review the pertinent literature regarding presentation, diagnosis, and management of these lesions.

Approximately 15-20% of patients with chronic obstructive pulmonary disease (COPD) also display characteristics of asthma. In May 2014, the asthma-COPD overlap syndrome (ACOS) was briefly addressed in the Global Initiative for Asthma (GINA) and Global Initiative for Chronic Obstructive Lung Disease (GOLD) strategy documents. We evaluated how pulmonologists diagnose and treat ACOS and how they assess its control. Pulmonologists from two university healthcare centers, having ≥ 1 year experience, treating patients with asthma, COPD, or ACOS, were invited to participate in focus groups. Two focus groups (1 hour duration) were convened with seven and five participants, respectively. According to pulmonologists from both institutions, ACOS is a new name for an existing syndrome rather than a new disease. It is characterized by incomplete reversible airflow limitations and changes in forced expiratory volume in one second over time. The pulmonologists noted that its diagnosis must be based on clinical characteristics, pulmonary function test results, and clinical intuition. To diagnose ACOS, pulmonologists must rely on their clinical judgment. They also agreed that the treatment of patients with ACOS should target the features of both asthma and COPD. Pulmonologists from both institutions used asthma control criteria to assess ACOS control. A deeper understanding would enable clinicians to establish specific criteria for the diagnosis, treatment, and follow-up of subjects with ACOS.

In endemic regions, visceral leishmaniasis is one of the most common opportunistic infections in HIV positive patients. Simultaneous infection with Leishmania and HIV has been reported in some countries but this is the first report of such a case in Iran. Our patient was a 27 years old man with intermittent night fever, abdominal pain, loss of appetite, vomiting, watery diarrhea and severe weight loss for 6 months. He had low socio-economic status with an imprisonment history. The patient was quite cachectic and had low grade fever. Physical exam and upper GI endoscopy revealed oropharyngeal candidiasis. Microscopic evaluation of duodenal biopsy material showed Leishmania amastigotes in macrophages of lamina propria. Leishman bodies were also observed in bone marrow aspiration specimen. Serologic tests were positive for Leishmania infantum. HIV antibody was also positive with a CD4+cell count of 80/μl. The diagnosis was acquired immunodeficiency syndrome with simultaneous visceral leishmaniasis involving intestinal mucosa.

Non-surgical treatment of obstructive sleep apnea syndrome.

Obstructive sleep apnea syndrome (OSAS), a pervasive disease, is closely associated with complications such as cardiovascular diseases, neurocognitive diseases, and metabolic syndromes. Continuous positive airway pressure (CPAP) is the standard treatment for OSAS, with low compliance due to multifarious factors. The two other modes of ventilation, bi-level positive airway pressure (BPAP) and autotitrating positive airway pressure (APAP), which were developed from CPAP, are slightly different from CPAP in specific groups, as well as the corresponding treatment effect and compliance. The compliance of traditional positional therapy is not high, but with the emergence of the neck-based position treatment device, its compliance and indications have changed. Although CPAP is superior to mandibular advancement device (MAD) in improving AHI, MAD seems to be comparable to CPAP in improving other indicators. Corticosteroids and leukotriene receptor antagonists are effective treatments for mild OSAS children. Whether corticosteroids can be used in other OSAS groups and their adjunctive functions to CPAP remains unclear. The combination of these two kinds of drugs appears to be more effective than single drug. Researches on transcutaneous electrical stimulation are still not enough. Its effectiveness and stimulation settings still need further study. This review summarized the various OSAS non-surgical treatments from indications, treatment outcomes, compliance, adverse reactions, and recent progress.

Endogenous glucagon-like peptide-2 (GLP-2) levels and intestinal adaptation are reduced in distal-intestinal resection animal models of short bowel syndrome (SBS) that lack remnant ileum. We hypothesized that exogenous GLP-2 would improve intestinal adaptation in a distal-intestinal resection neonatal piglet model of SBS. In all, 35 piglets were randomized to 2 treatment and 3 surgical groups: control (sham), 75% mid-intestinal resection (JI), and 75% distal-intestinal resection (JC). Parenteral nutrition (PN) commenced on day 1 and was weaned as enteral nutrition (EN) advanced. IV GLP-2 (11 nmol/kg/d) or saline was initiated on day 2. Piglets were maintained for 14 d. Clinical, functional, morphological, and histological outcomes were obtained. JC-GLP-2 piglets had fewer days on PN (10.0 ± 0.6 vs. 13.8 ± 0.2), more days on EN (4.0 ± 0.6 vs. 0.2 ± 0.2), a higher percentage of EN at termination (92 ± 5 vs. 52 ± 10%), fewer days of diarrhea (8.0 ± 0.7 vs. 12.3 ± 0.4), increased intestinal length (19 ± 4 vs. -5 ± 3%), and deeper jejunal crypts (248 ± 21 vs. 172 ± 12 μm), compared with saline piglets. GLP-2 therapy improves clinical, morphological, and histological outcomes of intestinal adaptation in a distal-intestinal resection model of SBS. Since this anatomical subtype represents the majority of clinical cases of neonatal SBS, these results support a potential role for GLP-2 therapy in pediatric SBS.

This study investigated the role of drug-induced sleep endoscopy (DISE) in the surgical treatment planning of patients with obstructive sleep apnea syndrome (OSAS). This study was conducted using patients diagnosed with OSAS between January 2007 and March 2009, who were scheduled for surgical treatment. DISE was performed using propofol in patients considered to have upper respiratory tract obstruction as indicated by Muller's maneuver. After completing the sleep endoscopy, the patient was intubated and surgery was performed (tonsillectomy and uvulopalatopharyngoplasty). A successful operation was defined as a decrease in the respiratory disturbance index to below 5 or a decrease of ≥50 % following the operation. The study included 20 patients (4 female and 16 male) aged 19-57 years. No statistically significant correlation between modified Mallampati class and operation success or between the polysomnographic stage of disease and operation success was identified. A significantly high operation success rate was found in the group with obstruction of the upper airway according to DISE (p < 0.05), whereas a significantly low operation success rate was found in the group with obstruction of the lower airway according to DISE (p < 0.01). DISE may be used to identify the localization of obstruction for diagnostic purposes, and it can be helpful in selecting the treatment method.

[Intrauterine intestinal volvulus].

Intrauterine intestinal volvulus is an extremely rare case of acute congenital intestinal obstruction. The diagnosis is usually possible in the third trimester of a pregnancy. Fetal midgut volvulus is most likely to be recognized by observing a typical clockwise whirlpool sign during color Doppler investigation. Multiple dilated intestinal loops with fluid levels are usually visible during the antenatal ultrasound as well. Physical and radiographic findings in the newborn indicate intestinal obstruction and an emergency surgery is required. The authors describe intrauterine volvulus in 3 female newborns in which surgical treatment was individualized. The decision about primary or delayed anastomosis after resection of the gangrenous part of the small bowel was made at the time of the surgery and depended on the general condition of the newborn, as well as presence or absence of meconium peritonitis. Double loop jejunostomy was performed in case of two newborns, followed by a delayed end-to-end anastomosis. In case of the third newborn, good blood supply of the small intestine after untwisting and 0.25% lignocaine injections into mesentery led to the assumption that the torsion was not complete and ischemia was reversible. In the two cases of incomplete rotation the cecum was sutured to the left abdominal wall to prevent further twisting. The postoperative course was uneventful and oral alimentation caused no problems. Physical development of all these children has been normal (current age: 1-2 years) and the parents have not observed any disorders or problems regarding passage of food through the alimentary canal. Prompt antenatal diagnosis of this surgical emergency and adequate choice of intervention may greatly reduce mortality due to intrauterine volvulus.

Fabricated induced illness (FII) is recognised amongst children presenting with suspected Chronic Intestinal Pseudo-Obstruction (CIPO) (Hyman 2012). We aimed to investigate the presence, nature and potential causes of social concerns in children being referred to our national centre with possible CIPO. All patients accepted into the CIPO diagnostic pathway over 3 years (April 2012-April 2015) were reviewed. Acceptance criteria included all of the following (1) referral from a paediatric gastroenterologist or surgeon suspecting a diagnosis of CIPO, (2) mechanical obstruction of the intestine excluded and 3) reliance on specialised enteral or parenteral feeding. The presence and nature of social concerns were recorded pre- & post-assessment along with associated characteristics pertaining to the referral, family situation as well as child protection. Comparison was made to referrals to the IBD service within the department. Of 78 accepted children (mean 5.2 years, 42F) 57 were diagnosed with CIPO, 53 (4.2yrs 31F) by abnormal antroduodenal manometry (ADM) and 4, unsuitable for ADM, by clinical picture. Of the remaining 21 patients (5.8yrs 12F) with normal ADM, 8 were found to have FII; 4 driven by a parent and 4 by the patient (teenage girls). The remaining 13 patients had non-CIPO diagnoses. Of those with normal ADM 17/21 had social concerns; 10 with formal child protection or FII and 7 with concerns over treatment compliance and ambiguity of symptoms. Of those with CIPO 18/57 had social concerns including 2 formally listed as child protection for neglect/parenting concerns and 1 with possible FII. The remaining CIPO cases had a variety of concerns mainly around ambiguity and reliability of reporting. Comparison with a newly diagnosed IBD cohort (161 patients) during the same period revealed only 7 with social concerns. Recurrent themes in those with social concerns, particularly CIPO, included consumerism, internet and media involvement (Facebook, fundraising and

Inflammation and oxidative stress in obstructive sleep apnea syndrome.

Similar to obesity, with which it is closely associated, obstructive sleep apnea syndrome (OSAS) is rapidly becoming a worldwide epidemic. Current knowledge of its pathogenesis has been significantly enriched by numerous experimental studies that have demonstrated an important role of oxidative stress and inflammation. Furthermore, new and exciting data strongly connect these two components in the perpetuation of the condition via the overexpression of nuclear factor kappaB. Experimental data support the hypothesis that nutrition might represent a promising future approach with antioxidants currently being good candidates for the modulation of cardiovascular sequelae, although weight reduction and controlled positive airway pressure remain the only established treatments for OSAS. We discuss herein the recent literature that illustrates these new paradigms and speculate on possible implications and future scenarios.

Budd-Chiari syndrome (BCS) is an uncommon clinical condition with a complex etiology. Pathogenesis of BCS is still poorly understood. We included hepatic veno-occlusive lesion tissues of 20 patients (patients group) with hepatic venous obstruction BCS and compared with 20 similar tissues with other etiologies (control group). Morphological changes in hepatic veno-occlusive lesion tissues and the positive expression of proliferating cell nuclear antigen (PCNA), C-myc, and P-53 were observed by the pathological examination (H&E staining) and immunohistochemistry assay. Our results showed that PCNA and C-myc positive cell densities were significantly higher in patient group than control group. P-53 positive cell density showed increasing trends in patients than control group. Moreover, we observed irregular hyperplasia in intimal tissue, fibrous connective tissue, and smooth muscle cell, accompanied by tissue degeneration (hyaloid degeneration and fibrinoid degeneration) and a large quantity of inflammatory cell infiltration. In conclusion, an overexpression of PCNA, C-myc, and a weak positive expression of P53 might launch the extremely irregular hepatic venous intimal hyperplasia, which is probably one of the etiologies of hepatic venous obstruction BCS.

To evaluate the effects of chlorella crude extract (CCE) on intestinal adaptation in rats subjected to short bowel syndrome (SBS). Wistar rats weighing 230-260 g were used in the study. After anesthesia a 75% small bowel resection was performed. Rats were randomized and divided into groups. Control group (n = 10): where 5% dextrose was given through a gastrostomy tube, Enteral nutrition (EN) group (n = 10): Isocaloric and isonitrogen EN (Alitraq, Abbott, USA), study group (n = 10): CCE was administrated through a gastrostomy tube. Rats were sacrificed on the fifteenth postoperative day and blood and tissue samples were taken. Histopathologic evaluation, intestinal mucosal protein and DNA levels, intestinal proliferation and apoptosis were determined in intestinal tissues, and total protein, albumin and citrulline levels in blood were studied. In rats receiving CCE, villus lengthening, crypt depth, mucosal DNA and protein levels, intestinal proliferation, and serum citrulline, protein and albumin levels were found to be significantly higher than those in control group. Apoptosis in CCE treated rats was significantly reduced when compared to EN group rats. CCE has beneficial effects on intestinal adaptation in experimental SBS.

Obstructive Sleep Apnea Syndrome: From Phenotype to Genetic Basis

Obstructive sleep apnea syndrome (OSAS) is a complex chronic clinical syndrome, characterized by snoring, periodic apnea, hypoxemia during sleep, and daytime hypersomnolence. It affects 4-5% of the general population. Racial studies and chromosomal mapping, familial studies and twin studies have provided evidence for the possible link between the OSAS and genetic factors and also most of the risk factors involved in the pathogenesis of OSAS are largely genetically determined. A percentage of 35-40% of its variance can be attributed to genetic factors. It is likely that genetic factors associated with craniofacial structure, body fat distribution and neural control of the upper airway muscles interact to produce the OSAS phenotype. Although the role of specific genes that influence the development of OSAS has not yet been identified, current researches, especially in animal model, suggest that several genetic systems may be important. In this chapter, we will first define the OSAS phenotype, the pathogenesis and the risk factors involved in the OSAS that may be inherited, then, we will review the current progress in the genetics of OSAS and suggest a few future perspectives in the development of therapeutic agents for this complex disease entity.

Massive scrotal edema: an unusual manifestation of obstructive sleep apnea and obesity-hypoventilation syndrome.

PubMed

Dreifuss, Stephanie E; Manders, Ernest K

2013-01-01

Obstructive sleep apnea (OSA) may occur in association with obesity-hypoventilation (Pickwickian) syndrome, a disorder of ventilatory control affecting individuals with morbid obesity. Through the pressor effects of chronic hypercapnia and hypoxemia, this syndrome may result in pulmonary hypertension, right heart failure, and massive peripheral edema. We present a case of severe scrotal edema in a 36-year-old male with OSA and obesity-hypoventilation syndrome. A tracheostomy was performed to relieve hypoxemia and led to dramatic improvement of scrotal edema. No scrotal surgery was necessary. Followup at two months showed complete resolution of scrotal edema, improvement in mental status, and normalization of arterial blood gas measurements. This case demonstrates that OSA and obesity-hypoventilation syndrome may present with massive scrotal edema. Furthermore, if OSA is recognized as the cause of right heart failure, and if the apnea is corrected, the resultant improvement in cardiac function may allow reversal of massive peripheral, including scrotal, edema.

[Physiological patterns of intestinal microbiota. The role of dysbacteriosis in obesity, insulin resistance, diabetes and metabolic syndrome].

PubMed

Halmos, Tamás; Suba, Ilona

2016-01-03

The intestinal microbiota is well-known for a long time, but due to newly recognized functions, clinician's attention has turned to it again in the last decade. About 100 000 billion bacteria are present in the human intestines. The composition of bacteriota living in diverse parts of the intestinal tract is variable according to age, body weight, geological site, and diet as well. Normal bacteriota defend the organism against the penetration of harmful microorganisms, and has many other functions in the gut wall integrity, innate immunity, insulin sensitivity, metabolism, and it is in cross-talk with the brain functions as well. It's a recent recognition, that intestinal microbiota has a direct effect on the brain, and the brain also influences the microbiota. This two-way gut-brain axis consists of microbiota, immune and neuroendocrine system, as well as of the autonomic and central nervous system. Emerging from fermentation of carbohydrates, short-chain fatty acids develop into the intestines, which produce butyrates, acetates and propionates, having favorable effects on different metabolic processes. Composition of the intestinal microbiota is affected by the circadian rhythm, such as in shift workers. Dysruption of circadian rhythm may influence intestinal microbiota. The imbalance between the microbiota and host organism leads to dysbacteriosis. From the membrane of Gram-negative bacteria lipopolysacharides penetrate into the blood stream, via impaired permeability of the intestinal mucosa. These processes induce metabolic endotoxaemia, inflammation, impaired glucose metabolism, insulin resistance, obesity, and contribute to the development of metabolic syndrome, type 2 diabetes, inflammarory bowel diseases, autoimmunity and carcinogenesis. Encouraging therapeutic possibility is to restore the normal microbiota either using pro- or prebiotics, fecal transplantation or bariatric surgery. Human investigations seem to prove that fecal transplant from lean

Medications can impact cognitive function. Obstructive sleep apnea syndrome (OSAS) is associated with cognitive impairment. There is currently a paucity of data evaluating the impact of medications on sleep architecture and cognition in untreated OSAS. Our objective was to evaluate the impact of obstructive sleep apnea syndrome (OSAS) and medications on cognition by a screening questionnaire called the Mail-In Cognitive Function Screening Instrument (MCFSI). We conducted a retrospective chart review on consecutive adults (age > 18 years) with OSAS seen in Medical University of South Carolina Sleep Clinic between January 1, 2012 and May 8, 2013, for whom the Mail-In Cognitive Function Screening Instrument (MCFSI) score was available and who were not on continuous positive airway pressure (CPAP). The correlation between different medications, sleep study variables, and MCFSI scores was studied. Univariate analysis revealed that many medications had significant correlations with MCFSI scores, including antidepressants (p = 0.05), antipsychotics (p = 0.01), anxiolytics (p = 0.005), statins (p = 0.077) and narcotics (p = 0.006). The mean percentage of rapid eye movement (REM) sleep (p = 0.04) and Epworth Sleepiness Scale (p = 0.01) were also significantly correlated with MCFSI scores. Multivariate analysis revealed that Epworth Sleepiness Scale and use of antipsychotics, narcotics, and anxiolytics correlated with higher MCFSI scores (worse cognition) and conversely that statin use was associated with improved cognition. Medications have a significant impact on cognitive function in OSAS. Thus, medication use should be considered in future studies of cognitive function in patients with OSAS.

The α subunit of the heterotrimeric G stimulatory protein (Gsa), encoded by the guanine nucleotide binding protein, α-stimulating gene (Gnas, in mice), is expressed ubiquitously and mediates receptor-stimulated production of cyclic adenosine monophosphate and activation of the protein kinase A signaling pathway. We investigated the roles of Gsa in vivo in smooth muscle cells of mice. We performed studies of mice with Cre recombinase-mediated disruption of Gnas in smooth muscle cells (Gsa SMKO and SM22-CreER T2 , induced in adult mice by tamoxifen). Intestinal tissues were collected for histologic, biochemical, molecular, cell biology, and physiology analyses. Intestinal function was assessed in mice using the whole-gut transit time test. We compared gene expression patterns of intestinal smooth muscle from mice with vs without disruption of Gnas. Biopsy specimens from ileum of patients with chronic intestinal pseudo-obstruction and age-matched control biopsies were analyzed by immunohistochemistry. Disruption of Gnas in smooth muscle of mice reduced intestinal motility and led to death within 4 weeks. Tamoxifen-induced disruption of Gnas in adult mice impaired contraction of intestinal smooth muscle and peristalsis. More than 80% of these died within 3 months of tamoxifen exposure, with features of intestinal pseudo-obstruction characterized by chronic intestinal dilation and dysmotility. Gsa deficiency reduced intestinal levels of cyclic adenosine monophosphate and transcriptional activity of the cyclic adenosine monophosphate response element binding protein 1 (CREB1); this resulted in decreased expression of the forkhead box F1 gene (Foxf1) and protein, and contractile proteins, such as myosin heavy chain 11; actin, α2, smooth muscle, aorta; calponin 1; and myosin light chain kinase. We found decreased levels of Gsa, FOXF1, CREB1, and phosphorylated CREB1 proteins in intestinal muscle layers of patients with chronic intestinal pseudo-obstruction

Knowledge of risk factors is particularly useful to prevent or manage pelvic floor dysfunction but although a number of such factors have been proposed, results remain inconsistent. The purpose of this study was to evaluate the impact of aging on the incidence of posterior pelvic floor disorders in women with obstructed defecation syndrome evaluated using echodefecography. A total of 334 patients with obstructed defecation were evaluated using echodefecography in order to quantify posterior pelvic floor dysfunction (rectocele, intussusception, mucosal prolapse, paradoxical contraction or non-relaxation of the puborectalis muscle, and grade III enterocele/sigmoidocele). Patients were grouped according to the age (Group I = patients up to 50 years of age; Group II = patients over 50 years of age) to evaluate the isolated and associated incidence of dysfunctions. To evaluate the relationship between dysfunction and age-related changes, patients were also stratified into decades. Group I included 196 patients and Group II included 138. The incidence of significant rectocele, intussusception, rectocele associated with intussusception, rectocele associated with mucosal prolapse and 3 associated disorders was higher in Group II, whereas anismus was more prevalent in Group I. The incidence of significant rectocele, intussusception, mucosal prolapse and grade III enterocele/sigmoidocele was found to increase with age. Conversely, anismus decreased with age. Aging was shown to influence the incidence of posterior pelvic floor disorders (rectocele, intussusception, mucosa prolapse and enterocele/sigmoidocele), but not the incidence of anismus, in women with obstructed defecation syndrome.

Intestinal adenocarcinomas were identified in 76 adult deer from a closed herd of 193 breeding animals grazing pasture heavily infested with bracken fern (Pteridium aquilinum). Tumors were observed postmortem in 32 animals with rapid weight loss, and similar neoplasms were detected in a further 44 clinically normal deer at "cull." Tumors were located in distal ileum, cecum, and proximal colon and presented as single (26%) or multiple (74%), variably sized, pale-gray, firm, poorly circumscribed neoplasms with associated intestinal strictures. Histopathologically tumors were well-differentiated, locally infiltrative, low-grade adenocarcinomas of tubular (51%), mucinous (33.5%), or mixed (15.5%) types. Extraintestinal metastases were not observed. The high incidence of intestinal adenocarcinoma within this herd suggests a specific and novel syndrome, and genetic and/or environmental factors may be involved in the pathogenesis. © The Author(s) 2014.

Duplications of the alimentary tract are congenital malformations. The ileum is the most commonly affected organ. A lot of duplications are incidentally diagnosed but most of patients present a combination of pain or complications such as obstructive symptoms, intestinal intussusception, perforation or volvulus. We report the case of a 6-years-old girl, with intermittent abdominal pain and vomits for two months long. Laboratory work was completely normal and in the radiology analysis (abdominal sonography and magnetic resonance) a cystic image with intestinal volvulus was observed. The patient underwent laparotomy, Ladd's procedure was done and the cyst was resected. In conclusion, if a patient is admitted with abdominal pain and obstructive symptoms, it is important to consider duplication of the alimentary tract as a possible diagnosis.

Introduction. The aim of the study was to evaluate our children who are operated on for anomalous congenital band while increasing the awareness of this rare reason of intestinal obstruction in children which causes a diagnostic challenge. Patients and Methods. We retrospectively reviewed the records of fourteen children treated surgically for intestinal obstructions caused by anomalous congenital bands. Results. The bands were located between the following regions: the ascending colon and the mesentery of the terminal ileum in 4 patients, the jejunum and mesentery of the terminal ileum in 3 patients, the ileum and mesentery of the terminal ileum in 2 patients, the ligament of Treitz and mesentery of the jejunum in one patient, the ligament of Treitz and mesentery of the terminal ileum in one patient, duodenum and duodenum in one patient, the ileum and mesentery of the ileum in one patient, the jejunum and mesentery of the jejunum in one patient, and Meckel's diverticulum and its ileal mesentery in one patient. Band excision was adequate in all of the patients except the two who received resection anastomosis for intestinal necrosis. Conclusion. Although congenital anomalous bands are rare, they should be considered in the differential diagnosis of patients with an intestinal obstruction.

Study Objectives: To investigate differences in cortical thickness in patients with obstructive sleep apnea (OSA) syndrome and healthy controls. Design: Cortical thickness was measured using a three-dimensional surface-based method that enabled more accurate measurement in deep sulci and localized regional mapping. Setting: University hospital. Patients: Thirty-eight male patients with severe OSA (mean apnea-hypopnea index > 30/h) and 36 age-matched male healthy controls were enrolled. Interventions: Cortical thickness was obtained at 81,924 vertices across the entire brain by reconstructing inner and outer cortical surfaces using an automated anatomical pipeline. Measurements: Group difference in cortical thickness and correlation between patients' data and thickness were analyzed by a general linear model. Results: Localized cortical thinning in patients was found in the orbitorectal gyri, dorsolateral/ventromedial prefrontal regions, pericentral gyri, anterior cingulate, insula, inferior parietal lobule, uncus, and basolateral temporal regions at corrected P < 0.05. Patients with OSA showed impaired attention and learning difficulty in memory tests compared to healthy controls. Higher number of respiratory arousals was related to cortical thinning of the anterior cingulate and inferior parietal lobule. A significant correlation was observed between the longer apnea maximum duration and the cortical thinning of the dorsolateral prefrontal regions, pericentral gyri, and insula. Retention scores in visual memory tests were associated with cortical thickness of parahippocampal gyrus and uncus. Conclusions: Brain regions with cortical thinning may provide elucidations for prefrontal cognitive dysfunction, upper airway sensorimotor dysregulation, and cardiovascular disturbances in OSA patients, that experience sleep disruption including sleep fragmentation and oxygen desaturation.

To evaluate the diagnosis value of photoplethysmography (PPG)-based device for detecting obstructive sleep apnea syndrome. Patients who visited sleep medicine center in West China hospital from March 2014 to March 2015 with a main complain of snoring were selected into this study, and they were simultaneously monitored with the PPG-based device while undergoing polysomnography (PSG). Using PSG as"gold standard", the sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV) as well as corresponding areas under the receiver operator curves for an apnea hypopnea index (AHI) ≥5/h, ≥15/h and ≥30/h were calculated for PPG. Valid results were available for 93 subjects, among them there were 64 men and 29 women with a mean age of (44±13) years old.There were no significant difference between total sleep time, wake time after sleep onset, AHI and oxygen saturation derived by PPG and PSG.Positive correlation was found between PPG-derived and PSG-derived AHI (r=0.945). For AHI≥5/h, ≥15/h and ≥30/h respectively according PSG, sensitivity was 93%, 88%, 92%, specificity was 79%, 93%, 95%, PPV was 95%, 97%, 96%, NPV 75%, 76%, 91% for PPG. The corresponding areas under the receiver operator characteristic curves were 0.981, 0.996 and 0.995 respectively. PPG-derived data is consistent with simultaneous in-lab PSG in the diagnosis of obstructive sleep apnea syndrome.

The Waardenburg-Shah syndrome is an autosomal recessive disease with varied penetration where Hirschsprung's disease and the Waardenburg syndrome are seen together. Although the length of the involved intestinal segment varies in this syndrome, most patients had total colonic aganglionosis with or without small bowel involvement. We present in this study 2 siblings and one first-degree relative for a total of 3 male patients with Waardenburg syndrome and total colonic aganglionosis with or without small bowel involvement, together with their clinical characteristics and treatment methods. The patients who presented with intestinal obstruction findings within the first 48 hours after birth were operated on with 2 patients under elective conditions and 1 as an emergency. The ganglionic segment lengths were 6, 8, and 20 cm, respectively. Aganglionic enterostomy was performed, and the Ziegler operation was used for these patients. The enterostomies started to function on the third postoperative week, and they started to gain weight. However, all died because of sepsis on the 5th to 12th month. Waardenburg-Shah syndrome patients have a higher incidence of total colonic aganglionosis with or without small bowel involvement. The Ziegler operation may be used in patients with inadequate ganglionic bowel length to gain some time for the child to grow and to decrease total parenteral nutrition complications.

Obstructive sleep apnea (OSA) is a common disorder characterized by the reduction or complete cessation in airflow resulting from an obstruction of the upper airway. Several studies have observed an increased risk for cardiovascular morbidity and mortality among OSA patients. Metabolic syndrome (MetS), a cluster of cardiovascular risk factors characterized by the presence of insulin resistance, is often found in patients with OSA, but the complex interplay between these two syndromes is not well understood. In this study, we present the results of a genetic association analysis of 373 candidate SNPs for MetS selected in a previous genome wide association analysis (GWAS). The 384 selected SNPs were genotyped using the Illumina VeraCode Technology in 387 subjects retrospectively assessed at the Internal Medicine Unit of the “Virgen de Valme” University Hospital (Seville, Spain). In order to increase the power of this study and to validate our findings in an independent population, we used data from the Framingham Sleep study which comprises 368 individuals. Only the rs11211631 polymorphism was associated with OSA in both populations, with an estimated OR=0.57 (0.42-0.79) in the joint analysis (p=7.21 × 10-4). This SNP was selected in the previous GWAS for MetS components using a digenic approach, but was not significant in the monogenic study. We have also identified two SNPs (rs2687855 and rs4299396) with a protective effect from OSA only in the abdominal obese subpopulation. As a whole, our study does not support that OSA and MetS share major genetic determinants, although both syndromes share common epidemiological and clinical features. PMID:23524009

Peutz-Jeghers Syndrome (PJS) is an uncommon autosomal dominant hamartomatous polyposis syndrome. Morbidity arises from polyp-related complications and increased risks of malignancy. We report on PJS patients registered in the Singapore Polyposis Registry, identified principal causes of morbidity and appraised current management strategies. A followup protocol based on recent literature has been proposed. A search of a prospectively collected database in the Singapore Polyposis Registry was made. Only patients who fulfilled the diagnostic criteria of PJS were included. The clinical records were retrieved for review. Information on affected family members was obtained from the Registry's pedigree records. Seven unrelated patients fulfilled the criteria of having PJS. Principal causes of morbidity include recurrent bouts of abdominal colic, episodes of intestinal obstruction, gastrointestinal bleeding and the need for repeated laparotomies. Six out of 7 patients had initial presentation with acute intestinal obstruction requiring emergency laparotomy. Management was mostly problem-oriented and marked inter-surgeon variation with regard to cancer screening and genetic counselling was observed. Patients with PJS suffer gastrointestinal complications from polyposis and are at increased risks for developing cancers. A move towards surveillance and planned comprehensive care may reduce the morbidity of the condition. A protocol driven approach conducted in the setting of a Polyposis Registry is ideally suited to facilitate such care.

Ingested magnets can cause intestinal fistulas, perforation, and obstruction. There have been reports of magnet ingestion causing intestinal volvulus, but multiple magnet ingestion causing perforation and intestinal volvulus in a child is very unusual. We report the case of a 4-year-old girl, who ingested four magnets she acquired as toys, which caused intestinal volvulus and perforation as a result of pressure necrosis, several days after ingestion. At surgery we repaired two perforations, but additional bowel resection was not required. The patient was discharged on postoperative day 10. If multiple magnet ingestion is suspected in a child, the child must be monitored carefully. If there are signs of obstruction, emergency surgery is mandatory.

We determined the distribution of the Arg16Gly and Gln27Glu polymorphisms of the beta-2 adrenergic receptor gene (ADRB2) in patients with obstructive sleep apnea syndrome as well as a control group in Northeastern Turkey. A total of 52 patients diagnosed with obstructive sleep apnea in a sleep laboratory and 78 control subjects were examined. Peripheral blood samples were taken from patients diagnosed with obstructive sleep apnea by polysomnography. DNA was extracted from blood samples and amplified using polymerase chain reaction. Amplification products were digested with restriction enzymes to investigate gene polymorphisms. Restriction products were extracted from agarose gel electrophoresis and polymorphisms were analyzed using gel images. The Arg16Gly polymorphism was observed in 18 of 52 patients and in 23 of 78 controls. The Gln27Glu polymorphism was observed in 21 of 52 patients and in 28 of 78 controls. In conclusion, there was no correlation among polymorphic frequencies between patient and control groups. Based on the results, these polymorphisms do not contribute to the clinical diagnosis of this syndrome. However, the distribution of Arg16Gly vs Gln27Glu polymorphisms may contribute to obesity in patients with a body mass index greater than 30 (P < 0.05). Different results may be obtained if the parameters of obstructive sleep apnea disease are changed.

Waugh’s Syndrome: Blessing in Disguise

PubMed Central

Mohanty, Subrat K

2014-01-01

Waugh’s syndrome is the association between intestinal malrotion and intussusceptions. We report a case of Waugh’s syndrome in a one year old child who presented to us with acute bowel obstruction and bleeding per rectum. Due to malrotation, there was easy prolapsing of ileocolic region into the nonfixed ascending colon and the intussusceptum advanced into the descending colon and rectum without compromising vascularity of the bowel. In most of the cases the intussusceptum advancing into the rectum is associated with bowel gangrene even when ceacum is mobile. But in our case, mobile caecum with malrotation proved to be blessing in disguise in preventing such a complication. A Meckel’s diverticulum was also an incidental finding in this case. Waugh's syndrome is missed in cases of close reduction of intussusception and may be a reason for recurrence. Though a rare entity, the probability of Waugh’s syndrome should be kept in mind during surgery, during hydrostatic reduction of intussusceptions, and in case of recurrent ileocolic intussusceptions.

Baguet, Jean-Philippe; Barone-Rochette, Gilles; Pépin, Jean-Louis

2009-04-01

Obstructive sleep apnea syndrome (OSAS), due to upper airway collapse, is frequent but still underestimated. The dose-response relation between OSAS and hypertension (HTN) is now well established. Logically, therefore, blood pressure must be tested in every apneic patient, if necessary by ambulatory blood pressure monitoring. Multiple mechanisms explain this relation, most importantly the increase in sympathetic activity during apnea episodes. OSAS-related hypertension has several characteristics: it is highly prevalent, predominantly diastolic and nocturnal, and frequently affects non-dippers; and the HTN tends to be resistant to treatment. OSAS promotes the formation of arterial lesions (parietal thickening of the carotid artery, increased aortic stiffness, and endothelial dysfunction); the more severe the OSAS, the more severe the lesions. The beneficial effects on blood pressure of continuous positive airway pressure (CPAP), the benchmark treatment for OSAS, are still debated but appear to be significant for untreated or refractory hypertension, for severe OSAS, and when CPAP compliance is good. It also seems promising for the reduction of arterial lesions linked to OSAS.

Mechanical small bowel obstruction following a blunt abdominal trauma: A case report

Introduction Intestinal obstruction following abdominal trauma has previously been described. However, in most reported cases pathological finding was intestinal stenosis. Presentation of the case A 51-year-old male was admitted after a motor vehicle accident. Initial focused abdominal sonogram for trauma and enhanced computerized tomography were normal, however there was a fracture of the tibia. Three days later, he complained of abdominal pain, constipation, and vomiting. An exploratory laparotomy showed bleeding from the omentum and mechanical small bowel obstruction due to a fibrous band. Discussion The patient had prior abdominal surgery, but clinical and radiological findings indicate that the impact of the motor vehicle accident initiated his condition either by causing rotation of a bowel segment around the fibrous band, or by formation of a fibrous band secondary to minimal bleeding from the omentum. Conclusion High index of suspicion of intestinal obstruction is mandatory in trauma patients presenting with complaints of abdominal pain, vomiting, and constipation despite uneventful CT scan.

We report 2 rare cases of afferent loop syndrome caused by obstruction at the jejuno-jejunostomy site in the Roux-en-Y loop after total gastrectomy, which was successfully treated by endoscopic balloon dilatation of the anastomotic stenosis. Case 1: A 62-year-old woman presented with malaise and lower abdominal distension 6 months after laparoscopy-assisted total gastrectomy with Roux-en-Y reconstruction. She was diagnosed with afferent loop syndrome; CT imaging indicated marked dilatation of the afferent loop, with membranous obstruction at the jejuno-jejunostomy site in the Roux-en-Y loop. Although almost complete occlusion was noted at the jejuno-jejunostomy site, the obstruction was successfully relieved by endoscopic balloon dilation using TandemTM XL Triple Lumen ERCP Cannula (Boston Scientific)®. Case 2: A 70-year-old man presented with malaise and lower abdominal distension 3 years after laparoscopy-assisted total gastrectomy with Roux-en-Y reconstruction. He was diagnosed with afferent loop syndrome; CT imaging indicated complete obstruction at the jejuno-jejunostomy site in the Roux-en-Y loop. As in case 1, the obstruction was successfully treated by endoscopic balloon dilatation of the occluded anastomosis.

Over the last decades, the incidence of infestation by minor parasites has decreased in developed countries. Infectious agents can also suppress autoimmune and allergic disorders. Some investigations show that various protozoa and helminthes are connected with the main immune-mediated intestinal conditions including celiac disease (CD), inflammatory bowel diseases (IBD) and irritable bowel syndrome (IBS). Celiac disease is a digestive and autoimmune disorder that can damage the small intestine and characterized by a multitude gastrointestinal (GI) and extra GI symptoms. IBD (including ulcerative colitis and Crohn’s disease) is a group of inflammatory conditions of the small intestine and colon. The etiology of IBD is unknown, but it may be related to instability in the intestinal microflora that leading to an immoderate inflammatory response to commensal microbiota. Irritable bowel syndrome (IBS) is a common, long-term condition of the digestive system. Bloating, diarrhoea and/or constipation are nonspecific symptoms of IBS. Various studies have shown that some intestinal parasites can effect on immune system of infected hosts and in some cases, they are able to modify and change the host’s immune responses, particularly in autoimmune disorders like celiac disease and IBD. The main objective of this review is to investigate the relationship between intestinal parasites and different inflammatory bowel disorders. PMID:25926937

Crockett, David Jeffrey; Goudy, Steven L.; Chinnadurai, Sivakumar; Wootten, Christopher Todd

2014-01-01

Introduction: Surgical treatment of velopharyngeal insufficiency (VPI) in 22q11.2 deletion syndrome is often warranted. In this patient population, VPI is characterized by poor palatal elevation and muscular hypotonia with an intact palate. We hypothesize that 22q11.2 deletion patients are at greater risk of obstructive sleep apnea (OSA) after surgical correction of VPI, due, in part, to their functional hypotonia, large velopharyngeal gap size, and the need to surgically obstruct the velopharynx. Methods: We performed a retrospective analysis of patients with 22q11.2 deletion syndrome treated at a tertiary pediatric hospital between the years of 2002 and 2012. The incidence of VPI, need for surgery, post-operative polysomnogram, post-operative VPI assessment, and OSA treatments were evaluated. Results: Forty-three patients (18 males, 25 females, ages 1–14 years) fitting the inclusion criteria were identified. Twenty-eight patients were evaluated by speech pathology due to hypernasality. Twenty-one patients had insufficient velopharyngeal function and required surgery. Fifteen underwent pharyngeal flap surgery, three underwent sphincter pharyngoplasty, two underwent Furlow palatoplasty, and one underwent combined sphincter pharyngoplasty with Furlow palatoplasty. Of these, eight had post-operative snoring. Six of these underwent polysomnography (five underwent pharyngeal flap surgeries and one underwent sphincter pharyngoplasty). Four patients were found to have OSA based on the results of the polysomnography (average apnea/hypopnea index of 4.9 events/h, median = 5.1, SD = 2.1). Two required continuous positive airway pressure (CPAP) due to moderate OSA. Conclusion: Surgery is often necessary to correct VPI in patients with 22q11.2 deletion syndrome. Monitoring for OSA should be considered after surgical correction of VPI due to a high occurrence in this population. Furthermore, families should be counseled of the risk of OSA after surgery and the

Congenital segmental dilatation (CSD) of the intestine is a rare developmental anomaly characterized by sharply demarcated dilatation of a gastrointestinal segment and may present with intestinal obstruction. We report three cases of CSD of the intestine in neonates with varied presentation. First patient was mistaken as pneumoperitoneum on abdominal radiograph, which led to initial abdominal drain placement. The 2nd patient was a case of anorectal malformation associated with congenital pouch colon (CPC) and CSD of ileum; and the third case presented as neonatal intestinal obstruction and found to have CSD of ileum. All the patients were successfully managed in our department. PMID:27896163

An 8-year boy was admitted to the ER of one of Warsaw's pediatric hospitals with a history of having bloody vomiting the day before. During admission the boy collapsed and lost consciousness. CPR was unsuccessful. On medico-legal autopsy, two foreign objects (small magnetic spheres--0.5 cm in diameter) were found in two different places in the small and large intestines and were notably attracted magnetically one to another. A loop of approximately 1-m length with features of small intestinal hemorrhagic necrosis and small intestinal mechanical obstruction was found. The cause of death was intestinal volvulus and small intestinal mechanical obstruction caused by ingestion of foreign objects (two neodymium magnets). Most likely these small magnetic spheres were part of a popular toy, the safety of which, lately, has been widely discussed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Epidemiological studies have suggested that obstructive sleep apnea syndrome (OSAS) may increase the risk of developing cognitive impairment. In patients with Alzheimer's disease (AD), the prevalence of OSAS is much higher than that expected in cognitively healthy subjects. A deeper knowledge of the pathophysiological link between OSAS and AD and the demonstration that OSAS may directly influence the development of cognitive alterations, would increase prevention and treatment strategies for AD patients. In this article, we discuss the evidence of the association between OSAS and dementia. Moreover, we present data about the functional and anatomic cerebral changes induced by OSAS and the possible effects on cognitive activities and on AD pathogenesis. The possibility to positively influence cognitive impairment by OSAS treatment will be also discussed.

Obstructive Sleep Apnea, Obesity, and the Development of Acute Respiratory Distress Syndrome

2014-01-01

Background: Obstructive sleep apnea (OSA) may increase the risk of respiratory complications and acute respiratory distress syndrome (ARDS) among surgical patients. OSA is more prevalent among obese individuals; obesity can predispose to ARDS. Hypothesis: It is unclear whether OSA independently contributes towards the risk of ARDS among hospitalized patients. Methods: This is a pre-planned retrospective subgroup analysis of the prospectively identified cohort of 5,584 patients across 22 hospitals with at least one risk factor for ARDS at the time of hospitalization from a trial by the US Critical Illness and Injury Trials Group designed to validate the Lung Injury Prediction Score. A total of 252 patients (4.5%) had a diagnosis of OSA at the time of hospitalization; of those, 66% were obese. Following multivariate adjustment in the logistic regression model, there was no significant relationship between OSA and development of ARDS (OR = 0.65, 95%CI = 0.32-1.22). However, body mass index (BMI) was associated with subsequent ARDS development (OR = 1.02, 95%CI = 1.00-1.04, p = 0.03). Neither OSA nor BMI affected mechanical ventilation requirement or mortality. Conclusions: Prior diagnosis of OSA did not independently affect development of ARDS among patients with at least one predisposing condition, nor the need for mechanical ventilation or hospital mortality. Obesity appeared to independently increase the risk of ARDS. Citation: Karnatovskaia LV, Lee AS, Bender SP, Talmor D, Festic E.

This study was conducted over a period of 2 years and comprised of a total of 18 patients of both sexes, from a pool of 64 patients who presented with clinical features of OSAS. All the surgeries were done by the same surgeon and standardised criteria for diagnosis was followed. Only those Patients who were diagnosed to have moderate to severe OSAS of the obstructive type with single level retro palatal obstruction were treated surgically with LAUP, and followed up for a period of 6 months. Of the 18 patients 16 reported of improvement in quality of life, as assessed by Functional Outcomes of Sleep Questionnaire (FOSQ), accounting for 88.8%. The results support the surgical treatment for OSAS of moderate to severe single level retro palatal type, as evidenced by the FOSQ scoring. LAUP is a very good surgical option in alleviating the symptoms of moderate to severe single level retro palatal OSAS.

Obesity has been associated with obstructive sleep apnea and hepatic steatosis. We investigated the effects of obstructive sleep apnea and treatment with nasal continuous positive airway pressure (CPAP) on serum aminotransferase levels in obese patients. We studied 40 obese men with obstructive sleep apnea syndrome. None had hepatitis B antigen or C antibody, autoimmune disease, or an excessive intake of alcohol. Serum levels of aspartate aminotransferase, alanine aminotransferase, triglyceride, glucose, insulin, and leptin were determined in the afternoon and in the morning immediately after sleep, before and after nasal CPAP treatment. Aminotransferase levels were abnormal in 35% (n = 14) of patients. Before treatment, mean (+/- SD) aspartate aminotransferase levels were higher in the morning than in the previous afternoon (presleep, 34 +/- 20 IU/L; postsleep, 39 +/- 28 IU/L; P = 0.006). The overnight mean increases in aminotransferase levels were less marked after the first night of nasal CPAP treatment (aspartate aminotransferase: from 6 +/- 11 IU/L to 2 +/- 6 IU/L, P = 0.0003; alanine aminotransferase: from 5 +/- 9 IU/L to 2 +/- 6 IU/L, P = 0.006). Leptin levels (n = 23) decreased significantly after treatment (P = 0.0002), whereas insulin resistance (calculated by the homeostasis model assessment method) and triglyceride levels were unchanged. Improvements in aspartate and alanine aminotransferase levels were maintained after 1 and 6 months of nasal CPAP treatment. Nasal CPAP therapy may have beneficial effects on serum aminotransferase abnormalities in obese patients who have obstructive sleep apnea. Copyright 2003 by Excerpta Medica Inc.

Aim: The herbal prescription Chang'an II is derived from a classical TCM formula Tong-Xie-Yao-Fang for the treatment of liver-qi stagnation and spleen deficiency syndrome of irritable bowel syndrome (IBS). In this study we investigated the effects of Chang'an II on the intestinal mucosal immune barrier in a rat post-inflammation IBS (PI-IBS) model. Methods: A rat model of PI-IBS was established using a multi-stimulation paradigm including early postnatal sibling deprivation, bondage and intrarectal administration of TNBS. Four weeks after TNBS administration, the rats were treated with Chang'an II (2.85, 5.71 and 11.42 g·kg−1·d−1, ig) for 14 d. Intestinal sensitivity was assessed based on the abdominal withdrawal reflex (AWR) scores and fecal water content. Open field test and two-bottle sucrose intake test were used to evaluate the behavioral changes. CD4+ and CD8+ cells were counted and IL-1β and IL-4 levels were measured in intestinal mucosa. Transmission electron microscopy was used to evaluate ultrastructural changes of the intestinal mucosal barrier. Results: PI-IBS model rats showed significantly increased AWR reactivity and fecal water content, and decreased locomotor activity and sucrose intake. Chang'an II treatment not only reduced AWR reactivity and fecal water content, but also suppressed the anxiety and depressive behaviors. Ultrastructural study revealed that the gut mucosal barrier function was severely damaged in PI-IBS model rats, whereas Chang'an II treatment relieved intestinal mucosal inflammation and repaired the gut mucosal barrier. Furthermore, PI-IBS model rats showed a significantly reduced CD4+/CD8+ cell ratio in lamina propria and submucosa, and increased IL-1β and reduced IL-4 expression in intestinal mucosa, whereas Chang'an II treatment reversed PI-IBS-induced changes in CD4+/CD8+ cell ratio and expression of IL-1β and IL-4. Conclusion: Chang'an II treatment protects the intestinal mucosa against PI-IBS through anti

Phytobezoar-induced small bowel obstruction is an uncommon clinical entity accounting for 2-4.8% of all mechanical intestinal obstructions. In addition, presentation with features of acute surgical abdomen is extremely rare, accounting for only 1% of the patients. The aim of this report is to present a very rare case of a phytobezoar-induced small bowel obstruction in a male patient who presented with acute surgical abdomen. A correct preoperative diagnosis was made based on the patient's history and characteristic imaging features on the emergency computed tomography (CT) scan. A 55-year-old man with previous gastrectomy presented with typical manifestations of acute abdomen. CT scan demonstrated dilatated small bowel loops and an intraluminal ileal mass with a mottled appearance. At exploratory laparotomy, a phytobezoar was found impacted in the terminal ileum and was removed through an enterotomy. Phytobezoar should be considered in patients with previous gastric outlet surgery who present with bowel obstruction and features of acute surgical abdomen. The presence of a well-defined intraluminal mass with a mottled gas pattern on emergency CT scan is suggestive of an intestinal phytobezoar. Copyright © 2013 Elsevier Inc. All rights reserved.

Necrotizing enterocolitis (NEC) is the most common intestinal emergency among premature infants. Risk factors in premature infants include immature intestinal immunity and an intestinal microbiota dominated by hospital-acquired bacteria. Some probiotics have been shown to decrease the incidence of NEC in premature infants. Among term infants, NEC is rare. However, among term infants with cyanotic congenital heart disease (CCHD), the incidence of NEC is similar to that of premature infants but with even greater mortality rates. Mechanisms by which NEC occurs in term infants with CCHD are unknown. Of central interest is the potential role of changes in the intestinal microbiota and whether these can be modified with probiotic bacteria; accordingly, we review the literature, propose hypotheses and present the rationale for future studies involving preliminary probiotic clinical trials.

Obstructive Sleep Apnoea/Hypopnoea Syndrome and Hypertension

The obstructive sleep apnoea/hypopnoea syndrome (OSAHS) is a common disorder, affecting around 2–4% of the middle-aged population. There is a strong association between OSAHS and hypertension, based on animal, large epidemiological and interventional studies. The epidemiological studies have shown a dose-response relationship between apnoea/hypopnoea index (AHI) and the risk of developing hypertension. Different mechanisms may have a role in the process of elevated blood pressure in OSAHS. Sympathetic activity is increased in OSAHS patients during sleep and wakefulness. This increase in sympathetic activity is probably due to activation of baroreflexes and chemoreflexes by frequent arousals and hypoxaemia a result of apnoea or hypopnoea events. Continuous positive airway pressure (CPAP) has been shown to reduce sympathetic stimulation and blood pressure in OSAHS patients. Altered endothelial function may also have a role in the pathogenesis of hypertension in OSAHS subjects. Reduction of nitric oxide (NO) production and increase in the formation of free radicals may be responsible for the impairment of the vasodilatation of micro-vasculature in these subjects as a result of hypoxaemia. It has been shown that effective CPAP therapy has a reversible effect on endothelial dysfunction. PMID:21748071

Obstructive defecation syndrome (ODS) presents a common medical problem, which can be caused by various pelvic disorders; multiple disorders are frequently diagnosed. At the present, a high number of corrective techniques are available via various surgical approaches. Laparoscopic resection rectopexy is a minimally invasive technique, which comprises redundant sigmoidal resection with rectal mobilisation and fixation. The aim of this paper was to evaluate the safety and effectiveness of laparoscopic resection rectopexy in the treatment of patients with ODS. The evaluation was performed via our own patients data analysis and via literature search focused on laparoscopic resection rectopexy. In total, 12 patients with ODS undergoing laparoscopic resection rectopexy in University Hospital Ostrava during the study period (2012-2015) were included in the study. In our study group, mean age was 64.5 years and mean BMI was 21.9; the group included 11 women (91.6%). ODS was caused by multiple pelvic disorders in all patients. Dolichosigmoideum and rectal prolapse (internal or external) were diagnosed in all included patients. On top of that, rectocoele and enterocoele were diagnosed in several patients. Laparoscopic resection rectopexy was performed without intraoperative complications; mean operative time was 144 minutes. Mean postoperative length of hospital stay was 7 days. Postoperative 30-day morbidity was 16.6%. All postoperative complications were classified as grade II according to Clavien-Dindo classification. Mean preoperative Wexner score was 23.6 points; mean score 6 months after the surgery was 11.3 points. Significant improvement in ODS symptoms was noted in 58.3% of patients, and a slight improvement in 16.6% of patients; resection rectopexy provided no clinical effect in 25% of patients. It is fundamental to carefully select those patients with ODS who could possibly profit from the surgery. Our results, in accordance with published data, suggest that

Background This study was performed to evaluate neck circumference (NC) and metabolic syndrome (MS) parameters in severe and non-severe (mild-moderate) obstructive sleep apnea syndrome (OSAS) patients according to apnea-hypopnea index (AHI). Material/Method We enrolled 44 patients diagnosed with OSAS based on overnight polysomnography. The diagnosis of OSAS was based on AHI. Apnea is a pause of airflow for more than 10 seconds. and hypopnea is a decrease of airflow for more than 10 seconds and oxygen desaturation of 4% or greater. AHI score. per hour; below 5 normal. 5–29 mild-moderate. 30 and above were grouped as severe OSAS. Height. weight. neck circumference (NC). waist circumference (WC) and body mass index (BMI) of the patients were measured. MS was diagnosed by the Adult Treatment Panel (ATP) III criteria (≥3 of the following abnormalities): 1) WC ≥94 cm for males, ≥80 cm for females; 2) arterial blood pressure ≥130/85 mmHg; 3) fasting blood glucose ≥100 mg/dl; 4) high density lipoprotein (HDL) cholesterol <40 mg/dl in man, <50 mg/dl in women; 5) triglycerides ≥150 mg/dl. Results Mean BMI and NC were higher in severe OSAS patients compared to non-severe patients (p=0.021. p<0.001). According to ATP III criteria. 64% of severe and 61.1% of non-severe OSAS patients were MS (p=0.847). A logistic regression model displayed an association with NC as a risk factor for severe OSAS (p=0.01). but not with MS. Conclusions In this study. NC in severe OSAS patients was significantly higher than in non-severe OSAS patients. The prevalence of metabolic syndrome was not correlated with OSAS severity. NC is an independent risk factor for severe OSAS. PMID:23403781

Obstructive sleep apnea syndrome in Prader-Willi Syndrome: an unrecognized and untreated cause of cognitive and behavioral deficits?

Prader-Willi Syndrome (PWS) is a rare genetic disorder characterized by a range of physical, psychological, and physiological abnormalities. It is also distinguished by the high prevalence of obstructive sleep apnea syndrome (OSAS), i.e., repetitive upper airway collapse during sleep resulting in hypoxia and sleep fragmentation. In non-PWS populations, OSAS is associated with a range of neurocognitive and psychosocial deficits. Importantly, these deficits are at least partly reversible following treatment. Given the findings in non-PWS populations, it is possible that OSAS may contribute to neurocognitive and psychosocial deficits in PWS. The present review examines this possibility. While acknowledging a primary contribution from the primary genetic abnormality to central neural dysfunction in PWS, we conclude that OSAS may be an important secondary contributing factor to reduced neurocognitive and psychosocial performance. Treatment of OSAS may have potential benefits in improving neurocognitive performance and behavior in PWS, but this awaits confirmatory investigation.

Surgery for obstructed defecation syndrome-is there an ideal technique

Obstructive defecation syndrome (ODS) is a common disorder with a considerable impact on the quality of life of affected patients. Surgery for ODS remains a challenging topic. There exists a great variety of operative techniques to treat patients with ODS. According to the surgeon’s preference the approach can be transanal, transvaginal, transperineal or transabdominal. All techniques have its advantages and disadvantages. Notably, high evidence based studies are significantly lacking in literature, thus making accurate assessments difficult. Careful patient’s selection is crucial to achieve optimal functional results. It is mandatory to assess not only defecation disorders but also evaluate overall pelvic floor symptoms, such as fecal incontinence and urinary disorders for choosing an appropriate and tailored strategy. Radiological investigation is essential but may not explain complaints of every patient. PMID:25574075

Study Objectives: To estimate the frequency of obstructive sleep apnea syndrome (OSAS) in dental patients with tooth wear, and to assess the role of dentists in the identification of patients at risk of OSAS. Methods: Dental patients with tooth wear and treated with occlusal splint were prospectively recruited to perform sleep study. The severity of tooth wear was established by the treating dentist before patient referral to sleep disorders unit. Sleep questionnaires, anthropometric measurements, and validated respiratory polygraphy were performed. Results: All patients with dental wear were offered a sleepiness analysis. Of 31 recruited patients, 30 (77% males) participated in this study. Patients' mean age was 58.5 ± 10.7 years (range: 35–90 years) and the body mass index was 27.9 ± 3.4 kg/m2. Tooth wear was mild in 13 patients, moderate in 8 and severe in 9. The mean apnea-hypopnea index (AHI) was 32.4 ± 24.9. AHI < 5 was reported in 2 patients, AHI of 5–29 in 17, and AHI ≥ 30 in 11. A statistically significant association was found between AHI severity and tooth wear severity (Spearman R = 0.505; p = 0.004). Conclusions: Tooth wear could be a tool to identify those patients at risk of having OSAS. This highlights the importance of dental professionals to identify and refer patients with OSAS.

Intestinal lymphangiectasia (IL) is a rare disease characterized by dilatation of intestinal lymphatics. It can be classified as primary or secondary according to the underlying etiology. The clinical presentations of IL are pitting edema, chylous ascites, pleural effusion, acute appendicitis, diarrhea, lymphocytopenia, malabsorption, and intestinal obstruction. The diagnosis is made by intestinal endoscopy and biopsies. Dietary modification is the mainstay in the management of IL with a variable response. Here we report 2 patients with IL in Bahrain who showed positive response to dietary modification.

The aim of research is to study of the spirometry figures of bronchoobstructive syndrome in concomitant intestinal parasitosis. There are 81 patients aged from 5 to 61 years (male 43, female 38) were examined. The patients were divided into 2 groups: 1 group - patients treated only with bronchodilator therapy (14 patients with protozoa, 14 - with helminth, 12 - with combination of parasitosis); 2 group - patients treated with bronchodilator therapy in common with anti-parasitic therapy (14 patients with protozoa, 17 - with helminth, 10 - with combination of parasitosis). There are 22 patients with bronchoobstructive syndrome without parasites were included in control group. Functional disorders at the initial examination are not significantly distinguished between patients with protozoa, helminth, with combined parasitosis and patients without parasites. Considerable differences manifested in dynamics after treatment: only bronchodilator therapy of patients infected with parasites is not lead to sufficient increase of the indices of external respiration function, even the decreasing of the most parameters were observed in patients with helminth. The least growth of spirometric indices were observed in patients from group 1 - 2,17/ 5,09% predicted volumes (-6,81min; 10,54max), the highest growth were observed in patients from group 2 - 20,26/ 12,45% p.v. (2,77min; 43,85max). The spirographic indicators increase after treatment in the control group was more moderate in comparison with 1 and 2 groups - 5,96/ 2,97% p.v. (0,39min; 9,59max). Thus, using antiparasitic therapy in common with bronchodilator therapy in treatment of patients with intestinal parasitosis (group 2) is lead to the reliably significant positive dynamic of spirometry parameters in comparison not only to 1 group (<0,05 for many parameters) but also to control group (<0,01 for many parameters).

Children with Down syndrome are at high risk of obstructive sleep apnoea (OSA) and screening is recommended. Diagnosis of OSA should be confirmed with multichannel sleep studies. We aimed to determine whether home pulse oximetry (HPO) discriminates children at high risk of OSA, who need further diagnostic multichannel sleep studies. Cross-sectional prospective study in a training sample recruited through three UK centres. Validation sample used single-centre retrospective analysis of clinical data. Children with Down syndrome aged 0.5-6 years. Diagnostic multichannel sleep study and HPO. Sensitivity and specificity of HPO to predict moderate-to-severe OSA. 161/202 children with Down syndrome met quality criteria for inclusion and 25 had OSA. In this training sample, the best HPO parameter predictors of OSA were the delta 12 s index >0.555 (sensitivity 92%, specificity 65%) and 3% oxyhaemoglobin (SpO 2 ) desaturation index (3% ODI)>6.15 dips/hour (sensitivity 92%, specificity 63%). Combining variables (delta 12 s index, 3% ODI, mean and minimum SpO 2 ) achieved sensitivity of 96% but reduced specificity to 52%. All predictors retained or improved sensitivity in a clinical validation sample of 50 children with variable loss of specificity, best overall was the delta 12 s index, a measure of baseline SpO 2 variability (sensitivity 92%; specificity 63%). HPO screening could halve the number of children with Down syndrome needing multichannel sleep studies and reduce the burden on children, families and health services alike. This approach offers a practical universal screening approach for OSA in Down syndrome that is accessible to the non-specialist paediatrician. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

We report the case of a 19-year-old military trainee that presented to the emergency department with a 3-week history of diffuse abdominal pain, 1 to 2 hours postprandially. The timing, onset, quality, and location of her pain was concerning for intestinal angina. Her serum chemistry, hematology, and liver function tests were normal. The radiologist's interpretation of the computed tomography angiogram of the abdomen was an abnormally narrow takeoff angle of the superior mesenteric artery (SMA) from the aorta near the third portion of the duodenum. She was diagnosed with SMA syndrome and received additional evaluation and treatment by her gastroenterologist and surgeon. SMA syndrome is rare and can cause bowel obstruction, perforation, gastric wall pneumatosis, and portal venous gas formation. Computed tomography angiography can be used to promptly diagnose this syndrome in the emergency department. Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.

2011-01-01

Previous studies have demonstrated morphological and biomechanical remodeling in the intestine proximal to an obstruction. The present study aimed to obtain stress and strain thresholds to initiate contraction and the maximal contraction stress and strain in partially obstructed guinea pig jejunal segments. Partial obstruction and sham operations were surgically created in mid-jejunum of male guinea pigs. The animals survived 2, 4, 7, and 14 days, respectively. Animals not being operated on served as normal controls. The segments were used for no-load state, zero-stress state and distension analyses. The segment was inflated to 10 cmH2O pressure in an organ bath containing 37°C Krebs solution and the outer diameter change was monitored. The stress and strain at the contraction threshold and at maximum contraction were computed from the diameter, pressure and the zero-stress state data. Young’s modulus was determined at the contraction threshold. The muscle layer thickness in obstructed intestinal segments increased up to 300%. Compared with sham-obstructed and normal groups, the contraction stress threshold, the maximum contraction stress and the Young’s modulus at the contraction threshold increased whereas the strain threshold and maximum contraction strain decreased after 7 days obstruction (P<0.05 and 0.01). In conclusion, in the partially obstructed intestinal segments, a larger distension force was needed to evoke contraction likely due to tissue remodeling. Higher contraction stresses were produced and the contraction deformation (strain) became smaller. PMID:21632056

The effect of a synthetic somatostatin analog was studied in a patient with severe secretory diarrhea due to pancreatic cholera syndrome. Basal intestinal perfusion studies indicated an absence of water and sodium absorption, and active chloride secretion in the small bowel. Intravenous administration of the somatostatin analog (1 microgram/kg.h) changed zero net water movement to absorption (122 mL/30 cm of the jejunum per hour). Chloride secretion changed to absorption (5.0 to 7.9 meq/30 cm.h), and plasma vasoactive intestinal polypeptide concentration was reduced from 330 to 45 pmol/L (normal, less than 51). When the analog was given subcutaneously, 100 micrograms twice daily, stool weight decreased, and plasma vasoactive intestinal polypeptide concentration fell toward the normal range (67 pmol/L). Plasma concentration of pancreatic polypeptide was initially elevated and dropped during intravenous infusion of somatostatin analog but returned to baseline on maintenance therapy with the analog delivered subcutaneously. The patient has not had further diarrhea during 9 months of therapy.

Objectives Small bowel volvulus is a rare disease, which is also challenging to diagnose. The aims of this study were to characterize the clinical and radiological features associated with small bowel volvulus and treatment and to identify risk factors for associated small bowel necrosis. Methods Patients with small bowel volvulus who underwent operations from January 2001 to December 2015 at the First Affiliated Hospital of China Medical University (Shenyang, China) were reviewed. Clinical, surgical and postsurgical data were registered and analyzed. Results Thirty-one patients were included for analysis. Fifteen patients were female (48.4%), with an average age of 47.7 years (18–79 years). The clinical signs and symptoms were unspecific and resembled intestinal obstruction. Clinical examination revealed abdominal distension and/or diffuse tenderness with or without signs of peritonitis. The use of CT scans, X-rays or ultrasound did not differ significantly between patients. In 9 of 20 patients that received abdominal CT scans, “whirlpool sign” on the CT scan was present. Secondary small bowel volvulus was present in 58.1% of patients, and causes included bands (3), adhesion (7), congenital anomalies (7) and stromal tumor (1). Out of the 31 patients, 15 with gangrenous small bowel had to undergo intestinal resection. Intestinal gangrene was present with higher neutrophils count (p<0.0001) and the presence of bloody ascites (p = 0.004). Three patients died of septic shock (9.68%), and the recurrence rate was 3.23%. Conclusions To complete an early and accurate diagnosis, a CT scan plus physical exam seems to be the best plan. After diagnosis, an urgent laparotomy must be performed to avoid intestinal necrosis and perforation. After surgery, more than 90% of the patients can expect to have a favorable prognosis.

Three patients died of septic shock (9.68%), and the recurrence rate was 3.23%. To complete an early and accurate diagnosis, a CT scan plus physical exam seems to be the best plan. After diagnosis, an urgent laparotomy must be performed to avoid intestinal necrosis and perforation. After surgery, more than 90% of the patients can expect to have a favorable prognosis.

Citrulline is a non-essential amino acid produced solely in the enterocyte. The aim of this study was to analyse the role of serum citrulline as a biomarker of enterocyte load in children with intestinal failure due to short bowel syndrome (SBS) and its relationship to enteral adaptation. Plasma citrulline concentration was determined by chromatography (normal value>15 μmol/L) in 57 patients (age 0.5-18 years) admitted to our Intestinal Rehabilitation Unit with intestinal failure. Those who were dehydrated, with renal insufficiency, or other conditions able to modify the results were excluded. Patients were divided into 4 groups: group i: SBS totally dependent on parenteral nutrition (PN); group ii: SBS under mixed enteral-parenteral nutrition; group iii: IF weaned from PN after a rehabilitation period; group iv: small bowel transplanted patients weaned from PN and taking a normal diet. The mean ± SD plasma citrulline values were: group i (n=15): 7.1 ± 4.1; group ii (n=11): 15.8 ± 8.9; group iii (n=13): 20.6 ± 7.5; group iv (n=25): 28.8 ± 10.1. Values were significantly lower in group i in comparison with groups ii-iii-iv (P<.001), and in group ii in comparison with groups iii-iv (P<.001). A low citrulline was associated with remnant small bowel length (P<.001, r=0.85). In group iv citrulline levels decreased >50% in 3 patients who developed moderate-severe rejection, and in one patient who developed viral enteritis. 1. Plasma citrulline could be a sensitive and specific biomarker of the residual functional enterocyte load. 2. It is related to enteral feeding tolerance. 3. Its prognostic value in the process of intestinal adaptation and as a rejection marker in small bowel transplanted patients needs to be confirmed. Copyright © 2012 Asociación Española de Pediatría.

Objective: To assess the correlation between obstructive sleep apnea hypopnea syndrome(OSAHS) and chronic obstructive pulmonary disease(COPD). Method: Databases such as Chinese Biomedical Literature Database, PubMed, Chinese Academic Journals full-text database, Wanfang Resource Database and Chongqing VIP have been searched to collect literatures about the relationship between OSAHS and COPD. The literature in conference proceedings and certain unpublished articles were also manually retrieved. RCT conformed to the condition was evaluated according to the standards of literature assessment, and the data has been extracted. The RevMan5.3 software was applied to carry out the same Metaanalysis. Result: Totally 19 articles were included, and Metaanalysis reveal that overlap syndrome(OS) patient's apnea hypopnea index is significantly higher than those of OSAHS patients［WMD=7.56, 95% CI （4.19,10.94）, P <0.01］; The LSaO₂ of OS patients is significantly lower than OSAHS patients［WMD=-10.50, 95% CI (-11.58, -6.08), P <0.01］; OS patients' FEV₁/FVC is significantly lower than COPD patients［WMD=4.65,95% CI （1.15,8.15）, P <0.01］.The results revealed that subgroup analysis according to the sample volume, age, body mass index(BMI) and FEV₁/FVC between OS patients and OSAHS patients has heterogeneity, but when analysis with the score of ESS the heterogeneity does not exist. Further, the subgroup analysis according to the sample volume, BMI, AHI,LSaO₂ and the time of Oxygen is lower than 90%(T90) those index between OS patients and COPD patients has heterogeneity, and the heterogeneity does not exist when subgroup is analyses with neck circumference. The funnel schema was nearly symmetry with little bias. Conclusion: The experimental results indicate that OSAHS is significantly related with COPD, and they may be the mutual risk factor for each other..

The relationship between physical activity and metabolic syndrome in people with chronic obstructive pulmonary disease.

PubMed

Park, Soo Kyung; Larson, Janet L

2014-01-01

The prevalence of metabolic syndrome has been reported to be 20% to 50% in people with chronic obstructive pulmonary disease (COPD). Because such people are sedentary and physically inactive, they are at risk of metabolic syndrome. The extent of this problem, however, is not fully understood. This study examined the relationship of sedentary time and physical activity to metabolic syndrome and the components of metabolic syndrome in a population-based sample of people with COPD. This was a secondary analysis of existing cross-sectional data. Subjects with COPD (n = 223) were drawn from the National Health and Nutrition Examination Survey data set (2003-2006). Physical activity was measured by accelerometry. Waist circumference, triglyceride level, high-density lipoprotein cholesterol level, blood pressure, and fasting glucose level were used to describe metabolic syndrome. Descriptive and inferential statistics were used for analysis. Fifty-five percent of the sample had metabolic syndrome. No significant differences in sedentary time and level of physical activity were found in people with COPD and metabolic syndrome and people with COPD only. However, those with a mean activity count of greater than 240 counts per minute had a lower prevalence of metabolic syndrome. Waist circumference and glucose level were significantly associated with the time spent in sedentary, light, and moderate to vigorous physical activity. Metabolic syndrome is highly prevalent in people with COPD, and greater physical activity and less sedentary time are associated with lower rates of metabolic syndrome. This suggests that interventions to decrease the risk of metabolic syndrome in people with COPD should include both reducing sedentary time and increasing the time and intensity of physical activity.

Patients with adhesive small intestine obstruction (ASIO) are difficult to evaluate and to manage and their treatment is still controversial. The diagnostic and therapeutic role of water-soluble contrast medium (Gastrografin) in ASIO is still debated. This study was designed to determine the therapeutic role of Gastrografin in patients with ASIO. The study was a multicenter, prospective, randomized, controlled investigation. The primary end points were the evaluation of the operative rate reduction and shortening the hospital stay after the use of Gastrografin. A total of 76 patients were randomized into two groups: the control group received traditional treatment (TT), whereas the study group (GG) received in addition a Gastrografin meal and follow-through study immediately. Patients with Gastrografin in the colon within 36 hours were considered to be partially obstructed and submitted to nonoperative management. If after 36 hours, the Gastrografin had not entered the colon, the subjects were submitted to laparotomy. No significant differences were found in age, sex, intravenous administration of prokinetics, incidence and characteristics of the previous procedures in surgical history of the patients, previous episodes of ASIO and surgery for adhesiolysis, or duration of symptoms before admission. In the GG group obstruction resolved subsequently in 31 of 38 cases (81.5%) after a mean time of 6.4 hours. The remaining seven patients were submitted to surgery, and one of them needed bowel resection for strangulation. In the control group, 21 patients were not submitted to surgery (55%), whereas 17 showed persistent untreatable obstruction and required laparotomy: 2 of them underwent bowel resection for strangulation. The difference in the operative rate between the two treatment groups reached statistical significance (p = 0.013). The time from the hospital admission for obstruction to resolution of symptoms was significantly lower in the GG group (6.4 vs. 43 hours

We report a case of eosinophilic granulomatosis with polyangiitis (EGPA; formerly known as Churg-Strauss syndrome) complicated by perforation of the small intestine and necrotizing cholecystitis. A 69-year-old man with a history of bronchial asthma was admitted with mononeuritis multiplex. The laboratory findings included remarkable eosinophilia. He was treated with corticosteroids and his laboratory indices showed improvement; however, his functional deficits remained. His neuropathy gradually improved after the addition of intravenous immunoglobulin (IVIG). He was subsequently treated with oral prednisolone (40 mg/day) as maintenance therapy. Within a month after finishing IVIG, he developed perforation of the small intestine and necrotizing cholecystitis. Intestinal perforation has often been reported as a gastrointestinal complication of EGPA. In contrast, cholecystitis is a rare complication. We report this case because the manifestation of more than one complication is extremely rare. Gastrointestinal symptoms may be a complication of EGPA itself and/or immunosuppressive treatment.

Radiation enteritis and radiation scoliosis

Any patient with radiation scoliosis should be suspected of having a visceral lesion as well. Chronic radiation enteritis may be manifested by intestinal obstruction, fistulas, perforation, and hemorrhage. Intestinal obstruction is the most common complication, and must be differentiated from postoperative cast or from spinal-traction syndrome. Obstruction that does not respond promptly to conservative measures must be treated surgically. Irradiated bowel is ischemic, and necrosis with spontaneous perforation can only be avoided with early diagnosis and surgical intervention.

Giant Meckel’s diverticulum: An exceptional cause of intestinal obstruction

PubMed Central

Akbulut, Sami; Yagmur, Yusuf

2014-01-01

Meckel’s diverticulum (MD) results from incomplete involution of the proximal portion of the vitelline (also known as the omphalomesenteric) duct during weeks 5-7 of foetal development. Although MD is the most commonly diagnosed congenital gastrointestinal anomaly, it is estimated to affect only 2% of the population worldwide. Most cases are asymptomatic, and diagnosis is often made following investigation of unexplained gastrointestinal bleeding, perforation, inflammation or obstruction that prompt clinic presentation. While MD range in size from 1-10 cm, cases of giant MD (≥ 5 cm) are relatively rare and associated with more severe forms of the complications, especially for obstruction. Herein, we report a case of giant MD with secondary small bowel obstruction in an adult male that was successfully managed by surgical resection and anastomosis created with endoscopic stapler device (80 mm, endo-GIA stapler). Patient was discharged on post-operative day 6 without any complications. Histopathologic examination indicated Meckel’s diverticulitis without gastric or pancreatic metaplasia. PMID:24672650

Background. A novel mutation in the ACTG2 gene is described in a pregnant patient followed up for chronic intestinal pseudoobstruction (CIPO) during pregnancy and her fetus with megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS). Case. 24-year-old gravida 1 para 1 with CIPO and persistent nausea and vomiting in pregnancy, admitted at 28 weeks of gestation. Ultrasound revealed a fetus measuring greater than the 95th percentile, polyhydramnios, and megacystis. At delivery, the newborn was noted to have an enlarged bladder, microcolon, and intolerance of oral intake. Genetic testing of mother and child revealed a novel mutation in the ACTG2 gene (C632F>A, p.R211Q). Conclusion. This is the first case in the literature describing a novel mutation in ACTG2 associated with visceral myopathy affecting both mother and fetus/neonate. Visceral myopathy should be included in the differential diagnosis of megacystis diagnosed by ultrasound, and suspicion should increase with family history of CIPO or MMIHS.

The nitric oxide precursor L-arginine (ARG) has been shown to influence intestinal morphology and intestinal absorptive function. The purpose of the present study was to determine the effect of enteral ARG supplementation on structural intestinal adaptation, cell proliferation, and apoptosis in a rat model of short bowel syndrome (SBS). Thirty male Sprague-Dawley rats were divided into three experimental groups: Sham rats underwent bowel transection, SBS rats underwent 75% small bowel resection, and SBS-ARG rats underwent bowel resection and were treated with ARG given in the drinking water (2%). Parameters of intestinal adaptation, enterocyte proliferation and enterocyte apoptosis were determined on day 14 following operation. We have demonstrated that SBS-ARG animals had a lower jejunal and ileal mucosal weight, jejunal mucosal DNA and protein, ileal mucosal protein, jejunal villus height, jejunal and ileal crypt depth, and enterocyte proliferation index and a greater enterocyte apoptosis compared to SBS untreated animals. We conclude that in a rat model of SBS enteral L-arginine inhibits structural intestinal adaptation. Possible mechanism for this effect may be decreased cell proliferation and increased cell apoptosis.

Intestinal anastomosis is a surgical procedure that restores bowel continuity after surgical resection to treat intestinal malignancy, inflammation, or obstruction. Despite the routine nature of intestinal anastomosis procedures, the rate of complications is high. Standard visual inspection cannot distinguish the tissue subsurface and small changes in spectral characteristics of the tissue, so existing tissue anastomosis techniques that rely on human vision to guide suturing could lead to problems such as bleeding and leakage from suturing sites. We present a proof-of-concept study using a portable multispectral imaging (MSI) platform for tissue characterization and preoperative surgical planning in intestinal anastomosis. The platform is composed of a fiber ring light-guided MSI system coupled with polarizers and image analysis software. The system is tested on ex vivo porcine intestine tissue, and we demonstrate the feasibility of identifying optimal regions for suture placement.

Study Objectives: To investigate differences in brain gray matter concentrations or volumes in patients with obstructive sleep apnea syndrome (OSA) and healthy volunteers. Designs: Optimized voxel-based morphometry, an automated processing technique for MRI, was used to characterize structural differences in gray matter in newly diagnosed male patients. Setting: University hospital Patients and Participants: The study consisted of 36 male OSA and 31 non-apneic male healthy volunteers matched for age (mean age, 44.8 years). Interventions: Using the t-test, gray matter differences were identified. The statistical significance level was set to a false discovery rate P < 0.05 with an extent threshold of kE > 200 voxels. Measurements and Results: The mean apnea-hypopnea index (AHI) of patients was 52.5/ h. On visual inspection of MRI, no structural abnormalities were observed. Compared to healthy volunteers, the gray matter concentrations of OSA patients were significantly decreased in the left gyrus rectus, bilateral superior frontal gyri, left precentral gyrus, bilateral frontomarginal gyri, bilateral anterior cingulate gyri, right insular gyrus, bilateral caudate nuclei, bilateral thalami, bilateral amygdalo-hippocampi, bilateral inferior temporal gyri, and bilateral quadrangular and biventer lobules in the cerebellum (false discovery rate P < 0.05). Gray matter volume was not different between OSA patients and healthy volunteers. Conclusions: The brain gray matter deficits may suggest that memory impairment, affective and cardiovascular disturbances, executive dysfunctions, and dysregulation of autonomic and respiratory control frequently found in OSA patients might be related to morphological differences in the brain gray matter areas.

Study Objectives: In children, most obstructive events occur during rapid eye movement (REM) sleep. We hypothesized that children with the obstructive sleep apnea syndrome (OSAS), in contrast to age-matched control subjects, would not maintain airflow in the face of an upper airway inspiratory pressure drop during REM sleep. Design: During slow wave sleep (SWS) and REM sleep, we measured airflow, inspiratory time, inspiratory time/total respiratory cycle time, respiratory rate, tidal volume, and minute ventilation at a holding pressure at which flow limitation occurred and at 5 cm H2O below the holding pressure in children with OSAS and in control subjects. Setting: Sleep laboratory. Participants: Fourteen children with OSAS and 23 normal control subjects. Results: In both sleep states, control subjects were able to maintain airflow, whereas subjects with OSAS preserved airflow in SWS but had a significant decrease in airflow during REM sleep (change in airflow of 18.58 ± 12.41 mL/s for control subjects vs −44.33 ± 14.09 mL/s for children with OSAS, P = 0.002). Although tidal volume decreased, patients with OSAS were able to maintain minute ventilation by increasing the respiratory rate and also had an increase in inspiratory time and inspiratory time per total respiratory cycle time Conclusion: Children with OSAS do not maintain airflow in the face of upper-airway inspiratory-pressure drops during REM sleep, indicating a more collapsible upper airway, compared with that of control subjects during REM sleep. However, compensatory mechanisms exist to maintain minute ventilation. Local reflexes, central control mechanisms, or both reflexes and control mechanisms need to be further explored to better understand the pathophysiology of this abnormality and the compensation mechanism.

Patients with obstructive sleep apnea syndrome usually present with changes in upper airway morphology and/or body fat distribution, which may occur throughout life and increase the severity of obstructive sleep apnea syndrome with age. To correlate cephalometric and anthropometric measures with obstructive sleep apnea syndrome severity in different age groups. A retrospective study of cephalometric and anthropometric measures of 102 patients with obstructive sleep apnea syndrome was analyzed. Patients were divided into three age groups (≥20 and <40 years, ≥40 and <60 years, and ≥60 years). Pearson's correlation was performed for these measures with the apnea-hypopnea index in the full sample, and subsequently by age group. The cephalometric measures MP-H (distance between the mandibular plane and the hyoid bone) and PNS-P (distance between the posterior nasal spine and the tip of the soft palate) and the neck and waist circumferences showed a statistically significant correlation with apnea-hypopnea index in both the full sample and in the ≥40 and <60 years age group. These variables did not show any significant correlation with the other two age groups (<40 and ≥60 years). Cephalometric measurements MP-H and PNS-P and cervical and waist circumferences correlated with obstructive sleep apnea syndrome severity in patients in the ≥40 and <60 age group.

2014-01-01

Prom1/CD133 has been identified in colorectal, hepatocellular, and pancreatic cancer as a cancer stem cell marker and has been used as such to predict colon cancer recurrence in humans. Its potential molecular function as well as its role as a marker of intestinal regeneration is still not fully known. We evaluated the role of Prom1 in intestinal regeneration in inflammatory bowel disease (IBD), determined the function of Prom1, and characterized the effect of a lack of Prom1 on intestinal tumor formation in animal models. Our results suggest that Apc mutations lead to an increase in Prom1 expressing cells in the intestinal crypt stem cell compartment and in early intestinal adenomas. Also, Prom1 knockout mice are more susceptible to intestinal tumor formation. We conclude that Prom1 likely plays a role in regulating intestinal homeostasis and that these results clearly illustrate the role of Prom1 in intestinal regeneration. We further conclude that Prom1 may provide a novel therapeutic target for patients with gastrointestinal conditions such as IBD, short bowel syndrome, and colorectal cancer. PMID:25452936

Forty-nine patients with a mean age of 25 months underwent a longitudinal intestinal lengthening procedure for short bowel syndrome (SBS) in our institution. Indications for the operation were dependence on parenteral nutrition in spite of adequate conservative management. The small bowel was lengthened from a mean of 27 cm to a mean of 51 cm. There was no intraoperative mortality. The following early complications occurred in our early series: ischemia of a short bowel segment of 2 cm, requiring resection in two patients, insufficiency of the longitudinal anastomosis in two patients and an intra-abdominal abscess in one. Four of 9 non-survivors died of liver failure and 3 of sepsis. Follow-up showed that 19 patients were weaned from parenteral nutrition after a mean of 9.1 months. Long-term complications encountered were dismotility with malabsorption due to bacterial overgrowth caused by progressive dilatation of the bowel, d-lactic acidosis, cholelithiasis and urolithiasis. A longitudinal intestinal lengthening procedure is an effective and safe surgical approach for SBS, provided it is performed in time, the patient's preoperative condition is optimized and technical surgical details are taken into account.

Background: Understanding the genetic transmission of obstructive sleep apnea syndrome (OSAS) will help clinicians identify patients at risk and offer opportunities for intervention and treatment at specialist clinics. Objective: To estimate familial risk of hospitalization for OSAS in the adult population of Sweden, and to determine if there are any differences by age and sex. Design, Setting, and Participants: Using the MigMed database at the Karolinska Institute, we divided the population of Sweden into sibling groups based on a shared mother and father and ascertained the presence or absence of a primary hospital diagnosis of OSAS in each individual during the follow-up period, 1997 to 2004. Individuals were categorized as having or not having a sibling with OSAS, based on the presence or absence of the disorder in at least 1 of their siblings. Standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) were estimated for men and women with a sibling with OSAS, compared with men and women in the reference group (SIR = 1). Results: After accounting for socioeconomic status, age, geographic region, and period of diagnosis, men with at least 1 sibling who had OSAS had a SIR of 3.42 (95% CI, 2.18–5.36); the corresponding SIR in women was 3.25 (95% CI, 1.84–5.65). Conclusions: Our results indicate that physicians should consider family history of OSAS when deciding whether to refer a patient for further sleep examinations.

Objective: Smoking is a known risk factor for snoring, and is reported to be associated with an increased prevalence of obstructive sleep apnea syndrome (OSAS). The purpose of this was to determine the relationship of smoking to the severity of OSAS and examine what local histological changes in the uvular mucosa of OSAS patients might influence this relationship. Study Design and Methods: Fifty-seven OSAS subjects were included and classified according to smoking history and OSAS severity. Twenty-eight subjects were heavy smokers and 29 were nonsmokers; these 57 patients were divided according to moderate or severe OSAS. Histologic changes in the uvular mucosa were evaluated in all subjects as well as smoking duration and OSAS severity. Results: Among smokers, moderate-to-severe OSAS was more common, and apnea, hypopnea, and oxygen desaturation indices were higher. Moreover, smoking duration and OSAS severity were significantly correlated. Increased thickness and edema of the uvular mucosa lamina propria were observed in moderate and severe OSAS patients, and only smokers had significant changes in uvular mucosa histology. Positive staining for calcitonin gene-related peptide (CGRP), a neuroinflammatory marker for peripheral nerves, was increased in the uvular mucosa of smokers. Conclusions: Our results suggest that smoking may worsen OSAS through exacerbation of upper airway collapse at the level of the uvula, and that histological changes of the uvular mucosa correlated with smoking might be due to increased CGRP-related neurogenic inflammation.

Energy absorption from a liquid test meal, intestinal transit rate and water and sodium output over a six hour period were measured in five patients with an ileostomy and 12 patients with the short bowel syndrome, five of whom were on longterm parenteral nutrition. The proportion of total energy absorbed was greatest in the ileostomists (median 87%, range 82-92%), less in short bowel patients not on parenteral nutrition (median 67%, range 59-78%, p less than 0.01) and least in the short bowel group who needed it (median 27%, range 2-63%, p less than 0.01). Transit rate was more rapid in the short bowel patients compared with the ileostomists. A close correlation was observed between percentage energy absorption and the dry weight of the stools/stoma effluent collected during the six hour test period (r = -0.99, p less than 0.001). This simple non-invasive test quantitates the degree of intestinal failure and may be of practical help in management. PMID:2495238

The various ill effects that tobacco smoking has on health have been largely studied, particularly on vascular, neoplastic, and respiratory diseases. Lately, the discussion about the negative impact of cigarette smoking moved towards sleep medicine. Tobacco consumption has been associated with sleep disordered architecture, both during regular intake and after withdrawal. Its effects on sleep disordered breathing (SDB) and especially obstructive sleep apnea syndrome (OSAS) still remain a matter of debate. It is unclear whether smoking represents a risk factor for OSAS or whether smoking cessation has any beneficial effects on OSAS and its therapy. There seems to be a synergistic effect between smoking and OSAS, both causing an increase in cardiovascular morbidity. Future studies are needed in order to establish the strength of this association. We aim to review the literature regarding the consequences of smoking on sleep architecture and SDB, adding emphasis on OSAS clinical implications and treatment.

We aimed to study survival and causes of death in patients with ST-elevation acute coronary syndrome (STE-ACS) with and without obstructive coronary artery disease (CAD). We included 4793 consecutive patients with STE-ACS triaged for acute coronary angiography at a large cardiac invasive centre (2009-2014). Of these, 88% had obstructive CAD (stenosis ≥50%), 6% had non-obstructive CAD (stenosis 1-49%), and 5% had normal coronary arteries. Patients without obstructive CAD were younger and more often female with fewer cardiovascular risk factors. Median follow-up time was 2.6 years. Compared with patients with obstructive CAD, the short-term hazard of death (≤30 days) was lower in both patients with non-obstructive CAD [hazard ratio (HR) 0.49, 95% confidence interval (CI) 0.27-0.89, P = 0.018] and normal coronary arteries (HR 0.31, 95% CI 0.11-0.83, P = 0.021). In contrast, the long-term hazard of death (>30 days) was similar in patients with non-obstructive CAD (HR 1.15, 95% CI 0.77-1.72, P = 0.487) and higher in patients with normal coronary arteries (HR 2.44, 95% CI 1.58-3.76, P < 0.001), regardless of troponin levels. Causes of death were cardiovascular in 70% of patients with obstructive CAD, 38% with non-obstructive CAD, and 32% with normal coronary arteries. Finally, patients without obstructive CAD had lower survival compared with an age and sex matched general population. STE-ACS patients without obstructive CAD had a long-term risk of death similar to or higher than patients with obstructive CAD. Causes of death were less often cardiovascular. This suggests that STE-ACS patients without obstructive CAD warrant medical attention and close follow-up. Published on behalf of the European Society of Cardiology.

To describe signalment, clinical findings, imaging and treatment of intestinal sand impaction in the dog. Medical records of dogs with radiographic evidence of small intestinal sand impaction were reviewed. Sand impaction resulting in small intestinal obstruction was diagnosed in eight dogs. All dogs presented with signs of vomiting. Other clinical signs included anorexia, lethargy and abdominal pain. Radiographs confirmed the presence of radio-opaque material consistent with sand causing distension of the terminal small intestine in all dogs. Four dogs were treated surgically for their impaction and four dogs were managed medically. Seven of the eight dogs survived. Both medical and surgical management of intestinal sand impaction in the dog can be effective and both afford a good prognosis for recovery.

Abstract. Intestinal anastomosis is a surgical procedure that restores bowel continuity after surgical resection to treat intestinal malignancy, inflammation, or obstruction. Despite the routine nature of intestinal anastomosis procedures, the rate of complications is high. Standard visual inspection cannot distinguish the tissue subsurface and small changes in spectral characteristics of the tissue, so existing tissue anastomosis techniques that rely on human vision to guide suturing could lead to problems such as bleeding and leakage from suturing sites. We present a proof-of-concept study using a portable multispectral imaging (MSI) platform for tissue characterization and preoperative surgical planning in intestinal anastomosis. The platform is composed of a fiber ring light-guided MSI system coupled with polarizers and image analysis software. The system is tested on ex vivo porcine intestine tissue, and we demonstrate the feasibility of identifying optimal regions for suture placement. PMID:26440616

Congenital intestinal lymphangiectasia is a disease which leads to protein losing enteropathy. Tortuous, dilated lymphatic vessels in the intestinal wall and mesenterium are typical features of the disease. Clinical manifestations include malabsorption, diarrhea, steatorrhea, edema and effusions. Specific diet and medication are required for disease control. A 19-year old male patient was hospitalized due to diarrhea, abdominal swelling, weariness and fatigue. Physical examination revealed growth impairment, ascites, and lymphedema of the right hand and forearm. Laboratory assessment indicated iron deficiency anaemia, lymphopenia, malabsorption, inflammatory syndrome, and urinary infection. Enteroscopy and video capsule endoscopy demonstrated dilated lymphatic vessels in the small intestine. The diagnosis was confirmed by intestinal biopsy. The patient was put on high-protein diet containing medium-chain fatty acids, somatotropin and supportive therapy. Congenital intestinal lymphangiectasia is a rare disease, usually diagnosed in childhood. Early recognition of the disease and adequate treatment can prevent development of various complications.

Sinusoidal obstruction syndrome (SOS) is a life-threatening complication generally occurring after hematopoietic stem cell transplantation. SOS after standard dose chemotherapy in malignancies is rare. Between the year 1995 and 2016, 414 patients were diagnosed with acute lymphoblastic leukemia and 113 patients were diagnosed with Wilms tumor in our institution. Among these patients, 4 patients with acute lymphoblastic leukemia (0.96%) and 2 patients with Wilms tumor (1.7%) developed SOS during treatment. SOS behaves like a local disseminated intravascular coagulation. Defibrotide has proved to be effective in SOS. In this article, we report our experience with defibrotide in SOS.

It is unknown whether short sleep duration, obstructive sleep apnea, and overnight shift work are associated with the risk of recurrent cardiovascular events in patients after an acute coronary syndrome. SOLID-TIMI 52 (The Stabilization of PLaques UsIng Darapladib-Thrombolysis in Myocardial Infarction 52 Trial) was a multinational, double-blind, placebo-controlled trial that enrolled 13 026 patients ≤30 days of acute coronary syndrome. At baseline, all patients were to complete the Berlin questionnaire to assess risk of obstructive sleep apnea and a sleep and shift work survey. Median follow-up was 2.5 years. The primary outcome was major coronary events (MCE; coronary heart disease death, myocardial infarction, or urgent revascularization). Cox models were adjusted for clinical predictors. Patients who reported <6 hours sleep per night had a 29% higher risk of MCE (adjusted hazard ratio, 1.29; 95% confidence interval, 1.12-1.49; P <0.001) compared with those with longer sleep. Patients who screened positive for obstructive sleep apnea had a 12% higher risk of MCE (1.12; 1.00-1.24; P =0.04) than those who did not screen positive. Overnight shift work (≥3 night shifts/week for ≥1 year) was associated with a 15% higher risk of MCE (1.15; 1.03-1.29; P =0.01). A step-wise increase in cardiovascular risk was observed for individuals with more than 1 sleep-related risk factor. Individuals with all 3 sleep-related risk factors had a 2-fold higher risk of MCE (2.01; 1.49-2.71; P <0.0001). Short sleep duration, obstructive sleep apnea, and overnight shift work are under-recognized as predictors of adverse outcomes after acute coronary syndrome. Increased efforts should be made to identify, treat, and educate patients about the importance of sleep for the potential prevention of cardiovascular events. URL: http://www.clinicaltrials.gov.

Crohn's disease (CD) is an autoimmune disease, which may cause obstructing intestinal strictures due to inflammation, fibrosis (deposition of collagen), or a combination of both. Identifying the different stages of the disease progression is still challenging. In this work, we indicated the feasibility of non-invasively characterizing intestinal strictures using photoacoustic imaging (PAI), utilizing the uniquely optical absorption of hemoglobin and collagen. Surgically removed human intestinal stricture specimens were investigated with a prototype PAI system. 2D PA images with acoustic resolution at wavelength 532, 1210 and 1310 nm were formulated, and furthermore, the PA histochemical components images which show the microscopic distributions of histochemical components were solved. Imaging experiments on surgically removed human intestinal specimens has demonstrated the solved PA images were significantly different associated with the presence of fibrosis, which could be applied to characterize the intestinal strictures for given specimens.

Of 72 patients with obstructive sleep apnea syndrome (OSAS) 32 had erectile dysfunction (ED). OSAS patients with erectile dysfunction had hypogonadism in 24 cases, in 8 men testosterone level was normal. A polysomnographic investigation with monitoring of nocturnal spontaneous erections showed that 32 patients had severe sleep fragmentation with reduced or complete absence of REM and deep sleep phases. In nocturnal penile tumescencia quantitative and qualitative characteristics were abnormal suggesting organic nature of erectile dysfunction in these patients. Eight ED and OSAS patients with normal testosterone received standard OSAS therapy with administration of FDE-5 type inhibitors. Six months later improvement of the erectile function was observed in 6 patients. OSAS patients with hypogonadism were divided into 2 groups. Group 1 (n = 5) received CPAP therapy and group 2 (n = 19) received OSAS standard therapy. Group 2 was treated with inhibitors of FDE-5 type. Three months later improvement of erectile function was seen only in 8. Group 1 received the inhibitors and testosterone replacement. Three months later all 5 patients had no ED complaints, their testosterone was normal. It is recommended to perform monitoring of nocturnal spontaneous erections in the algorithm of examination of all men with OSAS. All patients with OSAS, ED and documented hypogonadism need testosterone replacement therapy if its level persists low despite adequate therapy of OSAS.

Acute confusional syndrome, or delirium, is a transitory mental state characterized by the fluctuating alteration of awareness and attention levels. We present the case of a patient with acute confusional syndrome associated with obstructive sleep apnea syndrome (OSAS) aggravated by metabolic acidosis induced by oral acetazolamide treatment.A 70-year-old man with no history of neurological disease was referred with a clinical picture consistent with acute confusional syndrome presenting between midnight and dawn. During the admission examination infectious, toxic, and neurologic causes, or those related to metabolic or heart disease were ruled out. Arterial blood gases measured during one of the nighttime episodes of acute confusional syndrome showed mild hypoxia and hypercapnia with mixed acidosis. Signs and symptoms suggestive of OSAS had been developing over the months prior to admission, with snoring, sleep apnea, and moderate daytime drowsiness. Polysomnography demonstrated severe OSAS with an apnea-hypopnea index of 38. Mean arterial oxygen saturation was 83%; time oxygen saturation remained below 90% was 44%. The attending physician ordered the withdrawal of oral acetazolamide, which was considered the cause of the metabolic component of acidosis. Treatment with continuous positive airway pressure was initiated at 9 cm H2O, after a titration polysomnographic study. The patient continued to improve.OSAS, for which very effective treatment is available, should be included among diseases that may trigger acute confusional syndrome.

To present a rare anomaly consisting of uterus didelphys, longitudinal vaginal septum, obstructed hemivagina with pyocolpos, fistula to the open vaginal canal, and ipsilateral renal agenesis, referred as Herlyn-Werner-Wunderlich syndrome (HWWS). A 14-year-old girl with recurring purulent vaginal discharge lasting for a few months. Preoperative examination revealed one vaginal canal with one cervical opening on the right side. There was a fistula leading from the obstructed vaginal canal to the left vagina. Intravaginal ultrasound examination demonstrated a longitudinal vaginal septum and a closed pyocolpos on the right side. The longitudinal vaginal septum was excised by way of electrocauterization under direct vision. HWWS should be considered in the differential diagnosis in patients with uterus didelphys and unusual symptoms such as pyocolpos and vaginal discharge.

A 60-year-old man was admitted to our hospital because of a persistent fever with enlargement of multiple lymph nodes in the mediastinum and around the pancreatic head. He was diagnosed with tuberculosis and human immunodeficiency virus infection. We started antiretroviral therapy three weeks after the initiation of anti-tuberculous therapy. Two weeks later, jaundice appeared with dilatation of the biliary tract due to further enlargement of the lymph nodes, which seemed to be immune reconstitution inflammatory syndrome (IRIS). The administration of corticosteroids resolved the obstructive jaundice without surgical treatment or endoscopic drainage. Obstructive jaundice caused by IRIS should first be treated with corticosteroids before invasive treatment.

Obstructive sleep apnea (OSA) is now being recognized as an additional contributing factor to the pathogenesis of obesity-related comorbidities. At the same time, there is now increasing evidence to suggest that intestinal wall permeability plays a role in the development of metabolic syndrome. In the present study, circulating zonulin and fatty acid binding protein (I-FABP) were measured in association with metabolic, hepatic, and inflammatory parameters. Compared with controls, plasma I-FABP levels were significantly higher in patients with OSA (571 pg/mL [IQR 290-950] vs 396 pg/mL [IQR 234-559], p = 0.04). Zonulin levels were similar between groups. Significant relationships were observed between zonulin levels and waist circumference (p < 0.05), glucose (p < 0.05), and insulin (p < 0.05). In addition, in the OSA group, zonulin levels correlated negatively with the mean nocturnal oxygenation saturation (p < 0.05) and positively with total cholesterol (p < 0.05), alanine aminotransferase (ALT) (p < 0.005), aminotransferase (AST) (p < 0.01), gamma glutamyltransferase (GGT) (p < 0.005), and high-sensitivity C-reactive protein (hs-CRP) (p < 0.05). Multivariate analysis showed that associations between zonulin and ALT, AST, and hs-CRP were attenuated, but not eliminated, after adjustment for other variables. The results of this study suggest that OSA is a risk factor for intestinal damage, regardless of metabolic profile, and that intestinal permeability might be a possible contributor to nonalcoholic fatty liver disease in patients with OSA.

Intestinal Rotation Abnormalities and Midgut Volvulus.

PubMed

Langer, Jacob C

2017-02-01

Rotation abnormalities may be asymptomatic or may be associated with obstruction caused by bands, midgut volvulus, or associated atresia or web. The most important goal of clinicians is to determine whether the patient has midgut volvulus with intestinal ischemia, in which case an emergency laparotomy should be done. If the patient is not acutely ill, the next goal is to determine whether the patient has a narrow-based small bowel mesentery. In general, the outcomes for children with a rotation abnormality are excellent, unless there has been midgut volvulus with significant intestinal ischemia. Copyright © 2016 Elsevier Inc.

There are various hormones and growth factors which may modify the intestinal absorption of nutrients, and which might thereby be useful in a therapeutic setting, such as in persons with short bowel syndrome. In partI, we focus first on insulin-like growth factors, epidermal and transferring growth factors, thyroid hormones and glucocorticosteroids. Part II will detail the effects of glucagon-like peptide (GLP)-2 on intestinal absorption and adaptation, and the potential for an additive effect of GLP2 plus steroids. PMID:19152442

Intestinal lymphangiectasia is a rare autosomal dominant disorder or acquired condition that leads to lymph obstruction, poor chyle transport and concomitant problems. We describe the cases of two women with chronic diarrhea in whom the common signs of lymphagiectasia-hypoalbuminemia, lymphopenia and distal edema- were found. One of them also had pleural effusion and chylous ascites. The diagnosis was performed by intestinal biopsy. We herein review the histopathologic, radiographic and endoscopic features of this disorder and case reports in Mexican population.

Few data are available about the pattern of upper airway (UA) obstruction in children <2 years with obstructive sleep apnea syndrome (OSAS). Also, the role of adenoidectomy versus adenotonsillectomy (AT) is poorly defined in this age group. We performed drug-induced sedation endoscopy (DISE) in young OSAS children to investigate the pattern of UA obstruction and the value of DISE in therapeutic decision making. Retrospective analysis of ≤2-year-old children undergoing DISE-directed UA surgery. OSAS severity and the treatment outcomes were documented by polysomnography. Data are available for 28 patients, age 1.5 years (1.3-1.8), BMI-z score 0.5 (-0.7 to 1.3) with severe OSAS, obstructive apnea/hypopnea index (oAHI) 13.8/hr (7.5-28.3). All but 3 had (>50%) obstruction at the level of the adenoids, and all but 5 had (>50%) tonsillar obstruction. DISE-directed treatment consisted of adenoidectomy (n = 4), tonsillectomy (n = 1), and AT (n = 23). There was a significant improvement in respiratory parameters. Twenty children (71.4%) had a postoperative oAHI <2/hr. None had palatal or tongue base obstruction. Five children had a circumferential UA narrowing (hypotonia), 2 of them had residual OSAS. DISE showed a collapse of the epiglottis in 6 and late-onset laryngomalacia in 4. These findings did not affect surgical outcome. Adenotonsillar hypertrophy is the major cause of UA obstruction, and DISE-directed UA surgery was curative in 71,4% of children ≤2 years. We suggest that DISE may be helpful in surgical decision making. Circumferential UA narrowing may result in less favorable surgical outcomes.

Eco-Doppler evaluation of intestinal peristalsis in normal and in some pathological conditions: preliminary data.

Duplex-Doppler sonography could be employed in the quantitative investigation of intestinal motility. Preliminary data indicate reproductivity of the method in normal subjects and possible clinical applications in some pathological conditions affecting intestinal transit. Particularly, the possibility to discriminate between segments at different peristaltic activity seems to be very useful in intestinal obstruction. Further studies are necessary to validate this method.

BACKGROUND Intestinal Behçet's disease-like symptoms are rare complications of myelodysplastic syndrome and are often refractory to immunosuppressive therapies. We described a case of myelodysplastic syndrome complicated by Behçet's disease-like symptoms treated with prednisolone and azacitidine. CASE REPORT A 68-year-old Japanese woman was admitted to our hospital because of persistent high fever and lower abdominal pain. Oral ulcerations developed after admission, and multiple ulcers were found in her terminal ileum by endoscopic examination. She was diagnosed with myelodysplastic syndrome with trisomy 8 by bone marrow examination. Her symptoms diminished after administration of prednisolone, but relapsed afterwards. She began azacitidine therapy and her symptoms have been controlled for at least 10 months. CONCLUSIONS This case might suggest the possibility of azacitidine as a treatment option for myelodysplastic syndrome complicated by Behçet's disease-like symptoms.

Influence of defunctionalization and mechanical forces on intestinal epithelial wound healing

2012-01-01

The influence on mucosal healing of luminal nutrient flow and the forces it creates are poorly understood. We hypothesized that altered deformation and extracellular pressure mediate, in part, the effects of defunctionalization on mucosal healing. We created patent or partially obstructing defunctionalizing jejunal Roux-en-Y anastomoses in rats to investigate mucosal healing in the absence or presence of luminal nutrient flow and measured luminal pressures to document partial obstruction. We used serosal acetic acid to induce ulcers in the proximal, distal, and defunctionalized intestinal segments. After 3 days, we assessed ulcer area, proliferation, and phosphorylated ERK. In vitro, we measured proliferation and migration in Caco-2 and IEC-6 intestinal epithelial cells subjected to cyclic strain, increased extracellular pressure, or strain and pressure together. Defunctionalization of intestine without obstruction reduced phosphorylated ERK, slowed ulcer healing, and inhibited mucosal proliferation. This outcome was blocked by PD-98059. Partial obstruction delayed ulcer healing but stimulated proliferation independently of ERK. In vitro, strain increased Caco-2 and IEC-6 proliferation and reduced migration across collagen but reduced proliferation and increased migration across fibronectin. In contrast, increased pressure and the combination of pressure and strain increased proliferation and reduced migration independently of substrate. PD-98059 reduced basal migration but increased migration under pressure. These results suggest that loss of the repetitive distension may decrease mucosal healing in defunctionalized bowel, while increased luminal pressure above anastomoses or in spastic bowel disease could further inhibit mucosal healing, despite peristaltic repetitive strain. ERK may mediate the effects of repetitive deformation but not the effects of pressure. PMID:22997197

Pharmacological strategies to enhance adaptation in intestinal failure.

PubMed

Pape, Ulrich-Frank; Maasberg, Sebastian; Pascher, Andreas

2016-04-01

Intestinal failure because of more or less extensive resection of parts of the small and large intestine (short bowel syndrome) results from the reduction of absorptive surface of the remaining intestine and frequently results in dependence on parenteral nutrition. Parenteral nutrition, although lifesaving, is associated with short and long-term complications as well as with reduced quality of life and overall survival. Pharmacological enhancement of the physiological intestinal adaptive response by subcutaneous application of the glucagon-like peptide 2 analogue teduglutide results in an improved, hyperadaptive response. This is reflected by decreased parenteral calorie and fluid requirements, decreased parenteral nutrition infusion days per week including complete weaning off parenteral nutrition with complete oral autonomy, improved quality of life, and metabolic and nutritional stability. The advent of teduglutide as an authority-approved specific medication for intestinal failure in parenteral nutrition-dependent short bowel syndrome offers an effective and beneficial treatment for these patients. As a result, patients are more stable whether for medical or further surgical management including intestinal transplantation. Long-term efficacy and safety still have to be proven.

Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract. Most cases are asymptomatic; however, when symptomatic, it is often misdiagnosed at presentation. Common complications presenting in adults include bleeding, obstruction, diverticulitis, and perforation. Tumors within a Meckel's diverticulum are rare. Herein, we present a gastrointestinal stromal tumor arising from the Meckel's diverticulum that led to intestinal obstruction by volvulus.

We aimed to assess the prevalence of obstructive sleep apnea (OSA) in 8 year old school children with Down syndrome (DS). While the prevalence in otherwise healthy children is below 5%, the prevalence estimates in children with DS are uncertain (30-80%). OSA directly affects cognitive development and school performance. Population based cross sectional study in a limited geographical area. Polysomnography (PSG) with video and audio recordings was performed in 8-year-old children with DS in a pediatric sleep unit according to the guidelines of American Academy of Sleep Medicine. Twenty-nine of all 32 children with DS within a restricted area comprising >50% of the Norwegian population and 54% of the children with DS born in Norway in 2002 were enrolled. This study reports an apnea hypopnea index AHI>1.5 in 28 of 29 children and an obstructive apnea index (OAI)>1 in 24 of 29 children. 19 children (66%) had an AHI>5 and 17 children (59%) had an OAI>5 which indicated moderate to severe OSA. No correlation was found between OSA and obesity or gender. The high prevalence of disease found in these previously undiagnosed 8-year-old children underlines the importance of performing OSA diagnostics in children with DS throughout childhood. These findings suggest that the prevalence of OSA remains high up to early school years. In contrast to earlier publications, this current study has the advantage of being population based, the study is performed on children of a narrow age band to estimate prevalence of disease and the diagnostic gold standard of PSG is applied.

Stapled transanal rectal resection has become the primary surgical procedure for surgical treatment of obstructed defecation syndrome caused by rectocele or rectal intussusception. The procedure is generally performed with 2 circular staplers. Recently, a dedicated contour-curved stapler was developed. This study was designed to compare the effects of these stapler types on relief of symptoms. A randomized controlled trial was conducted at a regional referral center in Naples, Italy. Patients with obstructed defecation syndrome and rectocele or rectal intussusception, treated from November 2005 through September 2007. Participants were randomly assigned to undergo stapled transanal rectal resection with 2 circular staplers or the contour-curved stapler. The primary end point was success rate at 24 months, defined by symptom improvement on an obstructed defecation syndrome scale. Secondary end points included success rate at 12 months, Agachan-Wexner constipation score, and rates of early and late complications at 12 and 24 months. Of 198 patients evaluated, 63 patients (31.8%) satisfied criteria. Follow-up data were available for 61 patients: 30 patients (28 women) in the circular stapler group (mean age, 53; range, 41-75 years) and 31 (29 women) in the contour-curved stapler group (mean age, 55; range, 38-69 years). At 24-month follow-up, success was achieved in 21 patients (70.0%) with the circular staplers and in 27 (87.0%) with the contour-curved stapler (P = .10). Symptom scores improved significantly in both groups from baseline to 12 months (P < .0001). Improvement was maintained in the contour-curved stapler group: mean score, 5.0 (SD, 1.6) at 12 months and 5.5 (1.5) at 24 months (P = .20). In the circular stapler group, symptom scores worsened from 4.5 (1.5) at 12 months to 9.0 (1.3) at 24 months (P < .0001). At 24 months, the groups differed significantly in symptom scores (P < .0001) and constipation scores (P = .03). No significant differences were seen

Autoantibodies against voltage-gated potassium channels (VGKC-Abs) are associated with acquired neuromyotonia (Isaacs' syndrome) and related disorders such as Morvan's syndrome and some cases of limbic encephalitis. The mechanisms underlying the various phenotypes induced by VGKC-Abs are not fully understood. Recently, we reported a case of LE with VGKC-Abs accompanied by severe intestinal pseudo-obstruction and thymoma. Thymectomy and immunosuppressive therapy induced dramatic clinical improvement of LE symptoms, and VGKC-Abs titers decreased from 1254 pM to 549 pM (normal>100 pM). Seventeen months later, the patient developed progressive generalized muscle cramping, paresthesias in his lower extremities, excessive sweating, and severe constipation. There was no recurrence of the LE. Electromyography showed fasciculation potentials and myokymic discharges, and the plasma VGKC-Abs titer was again elevated to 879 pM. Here we report a case of Isaacs' syndrome after complete remission of LE with VGKC-Abs that may provide an insight into a possible link among VGKC-Abs associated syndromes.

To report a case of corneal neovascularization with secondary lipid keratopathy in a patient treated with continuous positive airway pressure (CPAP) for obstructive sleep apnea-hypopnea syndrome (OSAHS). A 49-year-old male had been diagnosed with obstructive sleep apnea syndrome 10 years ago and has been treated with the application of a CPAP machine during night sleep ever since. For the past year, the patient had been complaining for ocular irritation and excessive tearing of the left eye on awakening. Slit-lamp biomicroscopy revealed the presence of neovascularization and lipid exudation in the inferior third of the cornea of the left eye. Ocular patching during night sleep resulted in recession of the reported symptoms and shrinkage of the neovascularization, while the area of lipid exudation ceased to enlarge. To the best of our knowledge, this is the first report of corneal neovascularization in a patient using a CPAP machine for OSAHS.

The superior vena cava (SVC) syndrome in cystic fibrosis (CF) patients is rare, but presents unique challenges in the peri-transplant period. We reviewed our experience of SVC syndrome in CF recipients undergoing lung transplantation. This is a retrospective case series from a single center chart-review. SVC obstruction is defined by clinically significant stenosis or obstruction of the SVC as detected by contrast studies. We identified SVC obstruction in seven post-transplant cases and one pre-transplant case. All eight patients had previous or current history of indwelling central venous catheters. Three recipients experienced operative complications. Five of the seven recipients suffered at least one episode of post-operative SVC obstruction or bleeding despite prophylactic anticoagulation. At a median follow-up of 29 months, six of the seven patients transplanted are well. Strategies are available to minimize the risks of intra/peri-operative acute life-threatening SVC obstruction in CF patients. Copyright © 2014 European Cystic Fibrosis Society.

Sleep. 5: Driving and automobile crashes in patients with obstructive sleep apnoea/hypopnoea syndrome.

Driving is a complex task involving distinct cognitive, perceptual, motor, and decision making skills. After placing the vehicle on the road, the driver must constantly survey the ever changing roadway environment to keep the vehicle in the lane and moving at an appropriate safe speed. This surveillance involves two distinct visual tasks: estimating and responding to the oncoming curvature and controlling lane position. Driving is therefore a divided attention task involving speed and lane control as well as monitoring. To do this in a safe manner requires careful attention and alertness which can be problematic for patients with obstructive sleep apnoea/hypopnoea syndrome (OSAHS) or other sleep disorders.

Impact of Facial Conformation on Canine Health: Brachycephalic Obstructive Airway Syndrome

The domestic dog may be the most morphologically diverse terrestrial mammalian species known to man; pedigree dogs are artificially selected for extreme aesthetics dictated by formal Breed Standards, and breed-related disorders linked to conformation are ubiquitous and diverse. Brachycephaly–foreshortening of the facial skeleton–is a discrete mutation that has been selected for in many popular dog breeds e.g. the Bulldog, Pug, and French Bulldog. A chronic, debilitating respiratory syndrome, whereby soft tissue blocks the airways, predominantly affects dogs with this conformation, and thus is labelled Brachycephalic Obstructive Airway Syndrome (BOAS). Despite the name of the syndrome, scientific evidence quantitatively linking brachycephaly with BOAS is lacking, but it could aid efforts to select for healthier conformations. Here we show, in (1) an exploratory study of 700 dogs of diverse breeds and conformations, and (2) a confirmatory study of 154 brachycephalic dogs, that BOAS risk increases sharply in a non-linear manner as relative muzzle length shortens. BOAS only occurred in dogs whose muzzles comprised less than half their cranial lengths. Thicker neck girths also increased BOAS risk in both populations: a risk factor for human sleep apnoea and not previously realised in dogs; and obesity was found to further increase BOAS risk. This study provides evidence that breeding for brachycephaly leads to an increased risk of BOAS in dogs, with risk increasing as the morphology becomes more exaggerated. As such, dog breeders and buyers should be aware of this risk when selecting dogs, and breeding organisations should actively discourage exaggeration of this high-risk conformation in breed standards and the show ring.

Study Objectives: To assess the proportion of patients with obstructive sleep apnea hypopnea syndrome (OSAHS) reporting previous or current use and interest in future use of complementary and alternative medicine (CAM) therapies. Design: Cross-sectional, point-of-care, anonymous survey. Setting: Sleep disorders center at a Midwest tertiary care center. Participants: Six hundred forty-six consecutive patients undergoing polysomnography. Measurements: The survey instrument comprised 45 items specifically related to CAM therapies, in addition to obtaining baseline data. Results: Response rate was 81% (522/646). A total of 406/522 (78%) patients were diagnosed with OSAHS. Mean age ± SD was 57 ± 14 years, and 267 participants (66%) were men. Overall, 237 (58%) participants reported ever using CAM. Ever and current CAM use specifically for improving sleep was reported by 20% and 7% of the participants, respectively. Twenty-six percent of participants reported ever using biologic products, and 52% reported ever using nonbiologic CAM treatments. A high proportion (58%) of the participants showed interest in future CAM use for improving sleep. Conclusion: A high proportion of patients with OSAHS report previous or current use, and interest in future use, of CAM treatments. This underscores the need to conduct further research in this field. Citation: Sood A; Narayanan S; Wahner-Roedler DL; Knudsen K; Sood R; Loehrer LL; Hanson AC; Kuzniar TJ; Olson EJ.

Background: Obstructive sleep apnea (OSA) syndrome has a negative impact on the health of millions of adolescents and youth. The aim of this study was to evaluate the associations of OSA syndrome with obesity and cardiometabolic risk factors among adolescents and youth at risk for metabolic syndrome (MS). Methods: A total of 558 subjects aged 14–28 years were recruited from the Beijing Child and Adolescent Metabolic Syndrome Study. Each underwent a 2-h oral glucose tolerance test (OGTT), echocardiography, and liver ultrasonography. Anthropometric measures, blood levels of glucose, lipids, and liver enzymes were assessed. Subjects with high or low risk for OSA were identified by Berlin Questionnaire (BQ). Results: Among the subjects in obesity, 33.7% of whom were likely to have OSA by BQ. Subjects with high risk for OSA had higher neck and waist circumference and fat mass percentage compared to those with low risk for OSA (P < 0.001). Moreover, significant differences in levels of lipids, glucose after OGTT, and liver enzymes, as well as echocardiographic parameters were found between the two groups with high or low risk for OSA (P < 0.05). The rates of nonalcoholic fatty liver disease (71.0% vs. 24.2%), MS (38.9% vs. 7.0%), and its components in high-risk group were significantly higher than in low-risk group. Conclusions: The prevalence of OSA by BQ was high in obese adolescents and youth. A high risk for OSA indicates a high cardiometabolic risk. Mechanisms mediating the observed associations require further investigation. PMID:26315072

Little information is available regarding medical utilization and cost in patients with overlap syndrome of chronic obstructive pulmonary disease (COPD) and asthma. The purpose of this study is to analyze medical utilization and cost in patients with overlap syndrome and to compare them to COPD patients without asthma. Using the 2009 Korean National Health Insurance (NHI) database, COPD patients were identified. Medical utilization and costs were also analyzed. Of a total of 185,147 patients identified with COPD, 101,004 patients were classified with overlap syndrome of COPD and asthma and 84,143 patients with COPD without asthma. In 2009, the percentages of emergency room visits, admissions, and intensive care unit admissions were 14.6%, 30.5%, and 0.5%, respectively, in the patients with overlap syndrome group and 5.0%, 14.1%, and 0.2%, respectively, in the COPD patients without asthma group (p < 0.05 for all comparisons). The cost of medical utilization was 790 ± 71 US dollars per person and 3,373 ± 4,628 dollars per person for outpatient and inpatient services, respectively, in the patients with overlap syndrome and 413 ± 512 and 3,010 ± 5,013, respectively, in the COPD patients without asthma (p < 0.05 for all comparisons). Multiple linear regression showed that age, sex, overlap syndrome, hospitalization in the last year, low socioeconomic status, and type of hospital use were significant factors affecting medical utilization and cost. In patients with overlap syndrome, both medical utilization and cost were higher than in COPD patients without asthma.

The aim of the study was to determine some biochemical factors reflecting oxidant-antioxidant balance in the blood of patients being in different stages of the obstructive sleep apnea syndrome (OSAS). The patients, suspected of OSAS, were submitted to biochemical and somnographic examinations. APolyMesam device was used to establish the severity of apnea episodes. The control group was composed of subjects without OSAS. The following parameters were determined: concentration of plasma total antioxidant status, TAS; activity of erythrocyte Cu, Zn-superoxide dysmutase, SOD; plasma lipid peroxidation products, TBARS. The OSAS patients had lower levels of SOD and TAS, and increased level of TBARS. We conclude that oxidative stress markers increase in the blood of OSAS patients to a variable degree, depending on the severity of the syndrome and, therefore, may be suitable for a clinical follow-up of such patients.

This retrospective clinical study reports on the experience of palliative venting gastrostomy (PVG) in an integrated acute teaching hospital and hospice-based palliative care service over a seven-year period (1989-97). PVG was performed for 51 patients with refractory nausea and vomiting resulting from varying degrees and levels of persisting or intermittent malignant bowel obstruction. There were 32 females and 19 males; the mean age was 61 years (range 25-86 years). All patients had advanced and incurable cancer with intra-abdominal spread, originating from the following primary sites: colon and rectum (27), ovary (16), breast (2), pancreas (2), and other (4). The venting gastrostomy tube was inserted endoscopically by a railroading technique in 46 patients (using a 16- to 20-French Dobhoff PEG tube), at open laparotomy in four cases and under radiological (abdominal computerized tomography) control in one case. Endoscopic insertion was attempted and abandoned for technical reasons in a further two cases. The median survival of all 51 patients from the time of gastrostomy insertion was 17 days (range 1-190). In 47/51 (92%), the symptoms of nausea and vomiting were relieved by the procedure, and these patients experienced restoration of some level of oral soft food and fluid intake. Twenty patients were discharged home, and six died at home. In a small group of highly selected patients, for whom pharmacological measures failed to palliate the effects of malignant bowel obstruction, PVG was shown to be a safe and effective means of abolishing or substantially improving vomiting. Provided that the intervention is appropriate to the given clinical situation and acceptable to the patient, it should be considered.

What are the anatomic variants (and their frequencies) of double uterus, obstructed hemivagina and ipsilateral renal agenesis? Most cases examined (72.4%) were of the classic anatomic variant of the Herlyn-Werner-Wunderlich syndrome (with didelphys uterus, obstructed hemivagina and ipsilateral renal agenesis) but the 27.6% of cases are of a rare variant of the syndrome (with uterus septum or cervical agenesis), showing relevant clinical and surgical implications. The extreme variability of anatomic structures involved in this syndrome (both uterus, cervico-vaginal and renal anomalies) is well known, even if a complete and uniform analysis of all its heterogeneous presentations in a large series is lacking. This is a retrospective study with 87 patients referred to our third level referral center between 1981 and 2011. We analyzed the laparoscopic and chart records of 87 women, who referred to our institute with double uterus, unilateral cervico-vaginal obstruction and ipsilateral renal anomalies. Sixty-three of 87 patients had the more classic variant of didelphys uterus with obstructed hemivagina; 10/87 patients had septate bicollis uterus with obstructed hemivagina; 9/87 patients had bicornuate bicollis uterus with obstructed hemivagina; 4/87 patients had didelphys uterus with unilateral cervical atresia; 1/87 patients had bicornuate uterus with one septate cervix and unilateral obstructed hemivagina. This is a retrospective study with a long enrolling period (30 years). New insights in the anatomic variants of this rare syndrome with their relevant surgical implications.

We previously reported that the plasma level of endotoxin and colonic expression of IgA in the mouse increased with obstructive jaundice induced by bile duct ligation (BDL). To elucidate the mechanism of the BDL-induced increase, we analyzed the effect of BDL on intestinal flora in wild type and inducible nitric oxide synthase (iNOS)-deficient mice (iNOS−/−) using the terminal restriction fragment length polymorphism analysis (T-RFLP) and 16S rDNA clone libraries. The amounts of bacterial DNA detected in fecal samples from both animal groups pretreated with antibiotics were extremely low as compared with untreated groups. We found that the profiles of enteric bacteria changed markedly after BDL. The bacterial composition is significantly different between not only wild type and iNOS−/− mice but also those before and after BDL, respectively. Among enteric bacteria examined, Lactobacillus murinus was found to increase markedly after BDL in rectum of both animal groups. However, Escherichia coli markedly increased after BDL in the iNOS−/− mice. These findings suggest that profiles of enteric flora change markedly in animals during obstructive jaundice by some mechanism that is affected by bile constituents and iNOS-derived NO.

Insulin has been shown to influence intestinal structure and absorptive function. The purpose of the present study was to evaluate the effects of parenteral insulin on structural intestinal adaptation, cell proliferation, and apoptosis in a rat model of short bowel syndrome (SBS). Male Sprague-Dawley rats were divided into three experimental groups: sham rats underwent bowel transection and reanastomosis, SBS rats underwent a 75% small bowel resection, and SBS-INS rats underwent a 75% small bowel resection and were treated with insulin given subcutaneously at a dose of 1 U/kg, twice daily, from day 3 through day 14. Parameters of intestinal adaptation, enterocyte proliferation, and enterocyte apoptosis were determined on day 15 following operation. SBS rats demonstrated a significant increase in jejunal and ileal bowel and mucosal weight, villus height and crypt depth, and cell proliferation index compared with the sham group. SBS-INS animals demonstrated higher jejunal and ileal bowel and mucosal weights, jejunal and ileal mucosal DNA and protein, and jejunal and ileal crypt depth compared with SBS animals. SBS-INS rats also had a greater cell proliferation index in both jejunum and ileum and a trend toward a decrease in enterocyte apoptotic index in jejunum and ileum compared with the SBS untreated group. In conclusion, parenteral insulin stimulates structural intestinal adaptation in a rat model of SBS. Increased cell proliferation is the main mechanism responsible for increased cell mass.

Is it intestinal tuberculosis again? Case report.

Brat, Kristián; Merta, Zdeněk; Čundrle, Ivan

This case report focuses on an immigrant admitted to the Department of Respiratory Diseases, University Hospital Brno due to suspicion of relapsing intestinal tuberculosis. The patient presented with fever, night sweat, weight loss, diarrhea, and a history of several tuberculosis attacks in the last few years. None of the examinations confirmed the presence of active tuberculosis but raised suspicion of hematological malignancy. Pancytopenia was present in the peripheral blood. However, bone marrow examination and flowcytometry excluded the presence of a hematological malignancy. The results pointed to the possibility of vitamin B12 or folate deficiency that were both confirmed consequently by serum biochemical tests. Cobalamin and folate deficiency were caused by short bowel syndrome that developed after a major intestinal resection that the patient underwent in his past. Combined treatment including vitamins, pancreatic enzymes substitution, antidiarrhoics and spasmolytics was administered. The general health status of the patient improved rapidly with restitution of hematopoiesis, weight gain, and a decrease by 80% in daily number of stools. Clinical appearance of intestinal tuberculosis, short bowel syndrome and of cobalamin and folate deficiency as well as pathophysiology, diagnosis and treatment of these uncommon or even rare diseases are discussed in this case report.Key words: intestinal tuberculosis - pancytopenia - short bowel syndrome - vitamin B12 deficiency.

Excessive daytime sleepiness is a common symptom in obstructive sleep apnea (OSA). Previous studies have showed that excessive daytime sleepiness is associated with some individual components of metabolic syndrome. We performed a large cross-sectional study to explore the relationship between excessive daytime sleepiness and metabolic syndrome in male OSA patients. A total of 2241 suspected male OSA patients were consecutively recruited from 2007 to 2013. Subjective daytime sleepiness was assessed using the Epworth sleepiness scale. Anthropometric, metabolic, and polysomnographic parameters were measured. Metabolic score was used to evaluate the severity of metabolic syndrome. Among the male OSA patients, most metabolic parameters varied by excessive daytime sleepiness. In the severe group, male OSA patients with excessive daytime sleepiness were more obese, with higher blood pressure, more severe insulin resistance and dyslipidemia than non-sleepy patients. Patients with metabolic syndrome also had a higher prevalence of excessive daytime sleepiness and scored higher on the Epworth sleepiness scale. Excessive daytime sleepiness was independently associated with an increased risk of metabolic syndrome (odds ratio =1.242, 95% confidence interval: 1.019-1.512). No substantial interaction was observed between excessive daytime sleepiness and OSA/ obesity. Excessive daytime sleepiness was related to metabolic disorders and independently associated with an increased risk of metabolic syndrome in men with OSA. Excessive daytime sleepiness should be taken into consideration for OSA patients, as it may be a simple and useful clinical indicator for evaluating the risk of metabolic syndrome.

Drug-induced sleep endoscopy is a diagnostic technique that allows dynamic evaluation of the upper airway during artificial sleep. The lack of a standardized procedure and the difficulties associated with direct visual detection of obstructive events result in poor intraobserver and interobserver reliability, especially when otolaryngology surgeons not experienced in the technique are involved. To describe a drug-induced sleep endoscopy technique implemented with simultaneous polygraphic monitoring of cardiorespiratory parameters (DISE-PG) in patients with a diagnosis of obstructive sleep apnea syndrome and discuss the technique's possible advantages compared with the standard procedure. This prospective cohort study included 50 consecutive patients with obstructive sleep apnea syndrome who underwent DISE-PG from March 1, 2013, to June 30, 2014. A standard protocol was adopted, and all the procedures were carried out in an operation room by an experienced otolaryngology surgeon under the supervision of an anesthesiologist.

Obstructive sleep apnea syndrome (OSAS) and hypertension: Pathogenic mechanisms and possible therapeutic approaches

PubMed Central

Zhang, Wang

2012-01-01

Obstructive sleep apnea syndrome (OSAS), a chronic condition characterized by collapse of the pharynx during sleep, has been increasingly recognized as a health issue of growing importance over the last decade. Recently emerging evidence suggests that there is a causal link between OSAS and hypertension, and hypertension represents an independent risk factor in OSAS patients. However, the pathophysiological basis for patients with OSAS having an increased risk for hypertension remains to be elucidated. The main acute physiological outcomes of OSAS are intermittent hypoxia, intrapleural pressure changes, and arousal from sleep, which might induce endothelial dysfunction, sympathetic activation, renin–angiotensin–aldosterone system activation, lipid metabolism dysfunction, and increased oxidative stress. This brief review focuses on the current understanding of the complex association between OSAS and hypertension. PMID:23009224

Treatment of Obstructive Sleep Apnea Syndrome with Nasal Positive Airway Pressure Improves Golf Performance

Study Objectives: Obstructive sleep apnea syndrome (OSAS) is associated with impairment of cognitive function, and improvement is often noted with treatment. Golf is a sport that requires a range of cognitive skills. We evaluated the impact of nasal positive airway pressure (PAP) therapy on the handicap index (HI) of golfers with OSAS. Methods: Golfers underwent a nocturnal polysomnogram (NPSG) to determine whether they had significant OSAS (respiratory disturbance index > 15). Twelve subjects with a positive NPSG were treated with PAP. HI, an Epworth Sleepiness Scale (ESS), and sleep questionnaire (SQ) were submitted upon study entry. After 20 rounds of golf on PAP treatment, the HI was recalculated, and the questionnaires were repeated. A matched control group composed of non-OSAS subjects was studied to assess the impact of the study construct on HI, ESS, and SQ. Statistical comparisons between pre- and post-PAP treatment were calculated. Results: The control subjects demonstrated no significant change in HI, ESS, or SQ during this study, while the OSAS group demonstrated a significant drop in average HI (11.3%, p = 0.01), ESS, (p = 0.01), and SQ (p = 0.003). Among the more skilled golfers (defined as HI ≤ 12), the average HI dropped by an even greater degree (31.5%). Average utilization of PAP was 91.4% based on data card reporting. Conclusions: Treatment of OSAS with PAP enhanced performance in golfers with this condition. Treatment adherence was unusually high in this study. Non-medical performance improvement may be a strong motivator for selected subjects with OSAS to seek treatment and maximize adherence.

Intestinal failure is a rare, debilitating condition that presents both acute and chronic medical management challenges. The condition is incompatible with life in the absence of the safe application of specialized and individualized medical therapy that includes surgery, medical equipment, nutritional products, and standard nursing care. Intestinal rehabilitation programs are best suited to provide such complex care with the goal of achieving enteral autonomy and oral feeding with or without intestinal transplantation. These programs almost all include pediatric surgeons, pediatric gastroenterologists, specialized nurses, and dietitians; many also include a variety of other medical and allied medical specialists. Intestinal rehabilitation programs provide integrated interdisciplinary care, more discussion of patient management by involved specialists, continuity of care through various treatment interventions, close follow-up of outpatients, improved patient and family education, earlier treatment of complications, and learning from the accumulated patient databases. Quality assurance and research collaboration among centers are also goals of many of these programs. The combined and coordinated talents and skills of multiple types of health care practitioners have the potential to ameliorate the impact of intestinal failure and improve health outcomes and quality of life.

Drug-Induced Sleep Endoscopy is a method with which somnolence is pharmacologically induced and collapse is evaluated through nasal endoscopy in patients with Obstructive Sleep Apnea Syndrome. We aimed to evaluate efficiency of dexmedetomidine or propofol used for sedation in patients undergoing drug-induced sleep endoscopy. A total of 40 patients aged between 18 and 65 years old in the ASA STATUS I-II group were included in the study. After premedicatıon wıth midazolam 0.05 mg/kg intravenously, patients were randomly divided into two groups and administered intravenous (iv) propofol with the loading dose of 0.7 mg/kg for 10 minutes, followed 0.5 mg/kg/h infusion (Group P); or dexmedetomidine with the loading dose of 1 mcg/kg for 10 minutes, followed by 0.3 mcg/kg/h infusion (Group D). Haemodynamic and respiratuary parameters, Bispectral index score, Ramsey sedation score, time to achieve sufficient sedation, surgeon's and patients' satisfaction, postoperative Aldrete score and side effects were recorded. Time to achieve sufficient sedation, Bispectral index scores at 5, 10 and 15th. minutes intraoperatively, first Aldrete score in the recovery room, SpO2 values and respiratory rates all over the surgical procedure and in the recovery room were found lower in Group P (P<0.05). Bispectral index scores, mean arterial pressure and heart rate in the recovery room were significantly lower in Group D (P<0.05). Dexmedetomidine may be preferred as a safer agent with respecting to respiratory function compared with propofol in obstructive sleep apnea patients who known to be susceptible to hypoxia and hypercarbia.

Japan is an aging society, and the number of elderly patients with asthma and chronic obstructive pulmonary disease (COPD) is consequently increasing, with an estimated incidence of approximately 5 million. In 2014, asthma-COPD overlap syndrome (ACOS) was defined by a joint project of Global Initiative for Asthma (GINA) committee and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) committee. The main aims of this consensus-based document are to assist clinicians, especially those in primary care or nonpulmonary specialties. In this article, we discussed parameters to differentiate asthma and COPD in elderly patients and showed prevalence, clinical features and treatment of ACOS on the basis of the guidelines of GINA and GOLD. Furthermore, we showed also referral for specialized investigations.

Hepatic sinusoidal obstruction syndrome (SOS) is a life-threatening syndrome that generally occurs as a complication after hematopoietic stem cell transplantation or, less commonly, after conventional chemotherapy. Regarding SOS in rhabdomyosarcoma patients who received conventional chemotherapy, the doses of chemotherapeutic agents are associated with the development of SOS. Several cases of SOS in rhabdomyosarcoma patients after receiving chemotherapy with escalated doses of cyclophosphamide have been reported. Here, we report on a 9-year-old female with rhabdomyosarcoma who developed severe SOS after receiving chemotherapy consisting of vincristine, actinomycin-D, and a moderate dose of cyclophosphamide. She was treated successfully with defibrotide without sequelae to the liver.

To investigate the relationship of IL-1β and IL-6 cytokine gene polymorphisms with obstructive sleep apnea syndrome (OSAS) in 61 patients admitted to the neurology clinic in Kafkas University Hospital with insomnia problem who were diagnosed with OSAS in sleeping labs, and 80 healthy subjects not associated with the syndrome. METHODS :Blood samples were taken to isolate DNA from patients diagnosed with OSAS based on polysomnography results and healthy controls. DNA amplification of the genes was performed with PCR. Amplification products were cut with the restriction enzymes in order to determine IL-1 gene (TaqI) and IL-6 gene (Lwel) polymorphisms. The cut DNA fragments were carried out in agarose gel electrophoresis, and RFLP analysis was performed by utilizing the images with gel imaging system. PCR products were sequenced with an Applied Biosystems Automated Sequencer. Polymorphic changes were observed for IL-1β gene in 26 of 62 patients (41.9%), and 16 of the 80 (25.8%) in the control group. The incidence of polymorphic changes in IL-6 gene was in seen in seven (of the 62 patients) (11.3%), and in the 16 (20%) controls. The findings on the genomic level in OSAS may provide an important contribution to diagnosis of obstructive sleep apnea syndrome in clinical practice, as well as it helps to obtain the results easily about environmental and genetic interaction of OSAS patients.

We reviewed the sonographic and MRI findings of tracheolaryngeal obstruction in the fetus. Conditions that can cause tracheolaryngeal obstruction include extrinsic causes such as lymphatic malformation, cervical teratoma and vascular rings and intrinsic causes such as congenital high airway obstruction syndrome (CHAOS). Accurate distinction of these conditions by sonography or MRI can help facilitate parental counseling and management, including the decision to utilize the ex utero intrapartum treatment (EXIT) procedure.

As a result of the increasing of life expectancy, the incidence of pathologies that can lead to operation for bowel obstruction is also increasing. Comorbidities and reduced physiological reserve can decrease elderly patients' ability to tolerate operations especially in an emergency context. We retrospectively evaluated the treatment and outcomes of a cohort of patients aged more than 85 years who underwent emergency surgery for intestinal occlusion. 278 patients who were admitted to our Institution and operated for acute bowel obstruction have been included in our study. We divided the study population in 2 groups (group A: patients aged > 85 years old; group B patients aged ≤ 85 years). We evaluated the differences between the two groups in terms of intestinal occlusion aetiology, surgical procedures, morbidity and mortality rates. Group A consisted of 57 patients, group B of 221; elderly patients trend in ASA score classification was significantly towards high risk for elderly group; statistical analysis did not show differences in terms of bowel obstruction aetiology (except colon volvulus, more frequent in advanced age), type of procedure, duration of hospital stay, procedure - related complication rate. Perioperative mortality was significantly higher in elderly group, due to the mayor incidence of cardiovascular and respiratory fatal events directly related to pre - existing comorbidities. Despite the high surgical risk, early diagnosis and treatment of the obstructive disease can lead to achieve encouraging outcomes also in extremely advanced age; an aggressive evaluation of comorbidies and the cardio - respiratory risks reduction, when possible, could be useful in improve postoperative outcomes in terms of mortality.

Sonographic diagnosis of fetal intestinal volvulus with ileal atresia: a case report.

Fetal intestinal volvulus is a rare life-threatening condition usually manifesting after birth with most cases being associated with intestinal malrotation. It appears on prenatal sonography (US) as a twisting of the bowel loops around the mesenteric artery, leading to mechanical obstruction and ischemic necrosis of the bowel. We report a case of intrauterine intestinal volvulus with ileal atresia, suspected when US revealed a typical "whirlpool" sign at 37 weeks' gestation, with a segment of markedly distended bowel loops and small amount of fetal ascites.

Bowel dilatation occurs proximal to an obstruction and predisposes to intestinal dysmotility. The present study sought to determine whether or not changes in smooth muscle contractility and the thickness of the proximal, dilated bowel wall can be reversed following relief of the obstruction. Three groups of seven male Wistar rats were studied. In 8-week-old animals in a control group and a sham-operated group, a small segment of bowel (designated as R1 for controls and R2 for shams) was resected 5.0 cm from the cecum. In the third (operated) group, a narrow, isoperistaltic intestinal loop was created proximal to an end-to-end anastomosis of the ileum in 4-week-old animals. When these animals were 6 weeks old, the loop was re-anastomosed to the distal small bowel (after resection of the loop's distal portion, referred to as R3). Two weeks later, a small segment of bowel was resected proximal to the anastomosis (R4). We evaluated the thickness of the smooth muscle layers and the in vitro contractile responses of circular smooth muscle ileal strips (R1-R4) to electrical stimulation and pharmacological stimulation (with KCl, acetylcholine (ACh), substance P, N(G)-nitro-l-arginine methyl ester (L-NAME) and histamine). The amplitudes of contraction in response to electrical and Ach-mediated stimulation were higher for R3 than for R4 (P<0.001), R1 and R2 (both P<0.05). Compared with R1 and R2, the smooth muscle layer was three times as thick in R3 (P<0.001) and 2.5 times as thick in R4 (P<0.01). Our study provides evidence of the possible recovery of intestinal motility (in response to neurotransmitters involved in gut function) after the relief of an obstruction. If ileal motility can conceivably return to normal values, conservative surgical procedures in pediatric patients should be preferred (in order to leave a sufficient length of bowel and avoid short bowel syndrome). © 2013 Elsevier Inc.

Obstructive apnea during sleep is associated with peripheral vasoconstriction

Obstructive apnea during sleep is associated with a substantial transient blood pressure elevation. The mechanism of this pressor response is unclear. In this study we measured muscle sympathetic nerve activity (MSNA), mean arterial pressure (Psa), and mean limb blood velocity as an index of blood flow (MBV, Doppler) and calculated changes in limb vascular resistance during and after apneas during both wakefulness and sleep in patients with the obstructive sleep apnea syndrome. Immediately postapnea during sleep Psa increased significantly compared with the earlier stages of apnea and this was preceded by a rise of MSNA (n = 5). In contrast to blood pressure, MBV remained unchanged. Because resistance = blood pressure/blood flow, limb vascular resistance increased by 29 +/- 8% from late apnea to postapnea (n = 7, p < 0.002). Voluntary breathhold maneuvers during room air exposure evoked similar responses (n = 10). Supplemental oxygen administered via nonrebreather face mask attenuated the MSNA and vasoconstrictor responses to obstructive (n = 2) and voluntary apneas (n = 10). Our data suggest that obstructive apneas in patients with the obstructive apnea syndrome are accompanied by transient limb vasoconstriction. This vasoconstrictor response appears to be, at least in part, mediated by the sympathetic nervous system and may be linked to hypoxia.

The initial signs of hepatic sinusoidal obstruction syndrome (HSOS) can be challenging to recognize in children, especially outside the hematopoietic stem cell transplantation setting. To assist clinicians to promptly identify HSOS, the European Society for Blood and Marrow Transplantation has proposed pediatric HSOS diagnostic criteria which emphasize unexplained consumptive and transfusion-refractory thrombocytopenia. To highlight the importance of these "bellwether" early signs of HSOS and the efficacy of pre-emptive treatment with defibrotide, we describe the case of a child with a right 11th rib primitive neuroectodermal tumor who developed HSOS following focal radiotherapy and actinomycin-D treatment. © 2018 The Authors.

Study Objective: Positional therapy (PT) is an effective therapy in positional obstructive sleep apnea syndrome (POSAS) when used, but the compliance of PT is low. The objective of this study was to investigate whether a new kind of PT is effective and can improve compliance. Methods: 29 patients were treated with the sleep position trainer (SPT), 26 patients with the tennis ball technique (TBT). At baseline and 1 month polysomnography, Epworth Sleepiness Scale (ESS) and the Quebec Sleep Questionnaire (QSQ) were taken. Daily compliance was objectively measured in both groups. Results: Both therapies prevent supine sleep position to a median of 0% (min-max: SPT 0.0% to 67%, TBT 0.0% to 38.9%), resulting in a treatment success (AHI < 5) in 68.0% of the SPT and 42.9% of the TBT patients. The ESS at baseline was < 10 in both groups. Sleep quality parameters, such as wake after sleep onset (WASO; p = 0.001) and awakenings (p = 0.006), improved more in the SPT group. Total QSQ scores (0.4 ± 0.2, p = 0.03), the QSQ domains nocturnal symptoms (0.7 ± 0.2, p = 0.01), and social interactions (0.8 ± 0.3, p = 0.02) changed in favor of the SPT group. Effective compliance (≥ 4 h/night + ≥ 5 days/week) was 75.9% for the SPT and 42.3% for the TBT users (p = 0.01). Conclusion: In mild POSAS with normal EES the new SPT device and the standard TBT are equally effective in reducing respiratory indices. However, compared to the TBT, sleep quality, quality of life, and compliance improved significantly more in the SPT group.

To review the efficacy and safety of defibrotide as well as its pharmacology, mechanism of action, pharmacokinetics (PK), drug-drug interactions, dosing, cost considerations, and place in therapy. A PubMed search was performed through August 2017 using the terms defibrotide, oligonucleotide, hepatic veno-occlusive disease (VOD), sinusoidal obstruction syndrome (SOS), and hematopoietic cell transplantation (HCT). Other data sources were from references of identified studies, review articles, and conference abstracts plus manufacturer product labeling and website, the Food and Drug Administration website, and clinicaltrials.gov. English-language trials that examined defibrotide's pharmacodynamics, mechanism, PK, efficacy, safety, dosing, and cost-effectiveness were included. Trials have confirmed the safety and efficacy of defibrotide for treatment of VOD/SOS in adult and pediatric HCT patients, with complete response rates and day +100 overall survival rates ranging from 25.5% to 76% and 35% to 64%, respectively. The British Committee for Standards in Haematology/British Society for Blood and Marrow Transplantation Guidelines recommend defibrotide prophylaxis in pediatric and adult HCT patients with risk factors for VOD/SOS; however, its prophylactic use in the United States is controversial. Although there are efficacy data to support this strategy, cost-effectiveness data have not shown it to be cost-effective. Defibrotide has manageable toxicities, with low rates of grade 3 to 4 adverse effects. Defibrotide is the first medication approved in the United States for the treatment of adults and children with hepatic VOD/SOS, with renal or pulmonary dysfunction following HCT. Data evaluating defibrotide for VOD/SOS prevention are conflicting and have not shown cost-effectiveness.

Long standing hypothyroidism presenting as an ovarian mass has been well described in literature as the Van Wyk Grumbach syndrome (hypothyroidism, isosexual precocious puberty and ovarian mass). Here, authors report this entity in a 11 y 7 mo old girl child who was referred to a surgeon in view of intestinal obstruction along with a multiloculated ovarian cyst. On evaluation, she was found to have raised serum creatinine, short stature, delayed bone age and pituitary enlargement. She was diagnosed with autoimmune thyroiditis and was started on replacement therapy with thyroxine, after which the ovarian cysts regressed. This entity should be kept in mind in cases of ovarian cysts, especially those with isosexual precocity, to prevent unnecessary evaluation and surgical misadventures.

Sodium oxybate (SXB) is approved for cataplexy and excessive daytime sleepiness in narcolepsy. Obstructive sleep apnea syndrome (OSAS) affects ∼9-50% of narcoleptics. Effects of 2-week SXB administration on apnea-hypopnea index (AHI), oxygen saturation (SaO(2)), and sleep architecture were investigated in OSAS patients. OSAS patients (n = 48) received 2-week SXB or placebo (PBO) treatment with polysomnography at baseline and day 14. The primary outcome measure was change from baseline in mean AHI. Secondary outcomes included changes from baseline in SaO(2), and sleep architecture. Compared with PBO, SXB significantly increased reduction in mean AHI and obstructive apnea index with SXB (-0.8 ± 13.3 vs. -8.2 ± 10.0; p = 0.0327 and 3.54 ± 11.1 vs. -4.72 ± 7.7; p = 0.0054, respectively) and significantly increased change in slow wave sleep duration (5.2 ± 25.0 min vs. 29.4 ± 37.0 min; p = 0.0038). There were no differences between treatments in SaO2, central apneic events, or other measures. Adverse events, most commonly headache, were noted in nine of 27 (33%) and six of 23 (26%) patients receiving SXB and PBO, respectively. Short-term use of 4.5 g/night SXB did not generate respiratory depressant effects in OSAS patients as measured by AHI, obstructive apnea events, central apneas, and SaO2. Extended use of SXB in higher therapeutic doses in OSAS has not been studied, and merits caution.

Magnetic therapy is ineffective for the treatment of snoring and obstructive sleep apnea syndrome.

Snoring and the obstructive sleep apnea syndrome are common and chronic ailments with potentially serious medical complications. There are several accepted treatments, but these can be uncomfortable, inconvenient, and expensive. A number of alternative treatments have been reported to be beneficial in the treatment of obstructive sleep apnea and snoring. They are advertised in magazines, on the radio and television, and on the Internet. The lay press is reporting about the effectiveness of these treatments without the benefit of clinical trials or scientific studies. Among the therapies currently being promoted for the treatment of snoring and sleep apnea is biomagnetic therapy. Unlike many of the other treatments which have not undergone scientific evaluation, biomagnetic therapy has been evaluated in the past. In fact, the evaluation of biomagnetic therapy is one of the first controlled scientific investigations found in the literature. This report showed that magnet therapy had no medicinal value. Despite this clear evidence, magnetic therapy continues to be utilized today and currently is being promoted for the treatment of snoring and sleep apnea. At out Sleep Disorder Center, we have had the opportunity to evaluate a patient with severe obstructive sleep apnea both before and after treatment with magnetic therapy, as well as with conventional therapy. Our study clearly indicates there was no benefit from magnetic therapy in this case. While alternative therapy may be helpful in the treatment of certain medical conditions, extreme care must be exercised to prevent inappropriate treatment or undertreat-ment of significant medical problems. Close clinical follow-up and controlled studies are important in determining the effectiveness of therapies.

New Data Pre-processing on Assessing of Obstructive Sleep Apnea Syndrome: Line Based Normalization Method (LBNM)

NASA Astrophysics Data System (ADS)

Sleep disorders are a very common unawareness illness among public. Obstructive Sleep Apnea Syndrome (OSAS) is characterized with decreased oxygen saturation level and repetitive upper respiratory tract obstruction episodes during full night sleep. In the present study, we have proposed a novel data normalization method called Line Based Normalization Method (LBNM) to evaluate OSAS using real data set obtained from Polysomnography device as a diagnostic tool in patients and clinically suspected of suffering OSAS. Here, we have combined the LBNM and classification methods comprising C4.5 decision tree classifier and Artificial Neural Network (ANN) to diagnose the OSAS. Firstly, each clinical feature in OSAS dataset is scaled by LBNM method in the range of [0,1]. Secondly, normalized OSAS dataset is classified using different classifier algorithms including C4.5 decision tree classifier and ANN, respectively. The proposed normalization method was compared with min-max normalization, z-score normalization, and decimal scaling methods existing in literature on the diagnosis of OSAS. LBNM has produced very promising results on the assessing of OSAS. Also, this method could be applied to other biomedical datasets.

Intestinal obstruction due to a phytobezoar within a Meckel diverticulum is exceedingly rare, with only seven reported cases in the surgical literature. The most important precipitating factor is the ingestion of agents high in fiber and cellulose. Small bowel obstruction in all but one case was due to retrograde propagation of the bezoar into the small bowel lumen. We report the clinical and CT findings in such a patient following a vegetarian diet. 14 refs., 2 figs.

Obstructive sleep apnea syndrome has multifactorial causes. Although indications for surgery are evaluated by well-known diagnostic tests in the awake state, these do not always correlate with satisfactory surgical results. To undertake a systematic review on endoscopy during sleep, as one element of the diagnosis routine, aiming to identify upper airway obstruction sites in adult patients with OSAS. By means of electronic databases, a systematic review was performed of studies using drug-induced sleep endoscopy to identify obstruction sites in patients with OSAS. Ten articles were selected that demonstrated the importance of identifying multilevel obstruction, especially in relation to retrolingual and laryngeal collapse in OSAS. DISE is an additional method to reveal obstruction sites that have not been detected in awake patients. Copyright © 2015 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Recently, the intestinal microbiota has been emphasised as an important contributor to the development of metabolic syndrome. Dietary fibre may exert beneficial effects through modulation of the intestinal microbiota and metabolic end products. We investigated the effects of a diet enriched with two different dietary fibres, arabinoxylan and resistant starch type 2, on the gut microbiome and faecal short-chain fatty acids. Nineteen adults with metabolic syndrome completed this randomised crossover study with two 4-week interventions of a diet enriched with arabinoxylan and resistant starch and a low-fibre Western-style diet. Faecal samples were collected before and at the end of the interventions for fermentative end-product analysis and 16S ribosomal RNA bacterial gene amplification for identification of bacterial taxa. Faecal carbohydrate residues were used to verify compliance. The diet enriched with arabinoxylan and resistant starch resulted in significant reductions in the total species diversity of the faecal-associated intestinal microbiota but also increased the heterogeneity of bacterial communities both between and within subjects. The proportion of Bifidobacterium was increased by arabinoxylan and resistant starch consumption (P<0.001), whereas the proportions of certain bacterial genera associated with dysbiotic intestinal communities were reduced. Furthermore, the total short-chain fatty acids (P<0.01), acetate (P<0.01) and butyrate concentrations (P<0.01) were higher by the end of the diet enriched with arabinoxylan and resistant starch compared with those resulting from the Western-style diet. The concentrations of isobutyrate (P = 0.05) and isovalerate (P = 0.03) decreased in response to the arabinoxylan and resistant starch enriched diet, indicating reduced protein fermentation. In conclusion, arabinoxylan and resistant starch intake changes the microbiome and short-chain fatty acid compositions, with potential beneficial effects on colonic health

Study Objective: To (1) replicate our prior result of low cerebrospinal fluid (CSF) histamine levels in human narcolepsy in a different sample population and to (2) evaluate if histamine contents are altered in other types of hypersomnia with and without hypocretin deficiency. Design: Cross sectional studies. Setting and Patients: Sixty-seven narcolepsy subjects, 26 idiopathic hypersomnia (IHS) subjects, 16 obstructive sleep apnea syndrome (OSAS) subjects, and 73 neurological controls were included. All patients were Japanese. Diagnoses were made according to ICSD-2. Results: We found significant reductions in CSF histamine levels in hypocretin deficient narcolepsy with cataplexy (mean ± SEM; 176.0 ± 25.8 pg/mL), hypocretin non-deficient narcolepsy with cataplexy (97.8 ± 38.4 pg/mL), hypocretin non-deficient narcolepsy without cataplexy (113.6 ± 16.4 pg/mL), and idiopathic hypersomnia (161.0 ± 29.3 pg/mL); the levels in OSAS (259.3 ± 46.6 pg/mL) did not statistically differ from those in the controls (333.8 ± 22.0 pg/mL). Low CSF histamine levels were mostly observed in non-medicated patients; significant reductions in histamine levels were evident in non-medicated patients with hypocretin deficient narcolepsy with cataplexy (112.1 ± 16.3 pg/mL) and idiopathic hypersomnia (143.3 ± 28.8 pg/mL), while the levels in the medicated patients were in the normal range. Conclusion: The study confirmed reduced CSF histamine levels in hypocretin-deficient narcolepsy with cataplexy. Similar degrees of reduction were also observed in hypocretin non-deficient narcolepsy and in idiopathic hypersomnia, while those in OSAS (non central nervous system hypersomnia) were not altered. The decrease in histamine in these subjects were more specifically observed in non-medicated subjects, suggesting CSF histamine is a biomarker reflecting the degree of hypersomnia of central origin.

Obstructive Sleep Apnoea Syndrome (OSAS) is a respiratory disorder characterized by recurrent airflow obstruction caused by total or partial collapse of the upper airway. OSAS is an established independent factor of cardiovascular risk together with other risk factors such as smoking and increased lipids. The aim of our study was to measure serum levels of aldosterone and renin in OSAS patients that did not suffer from arterial hypertension and compare them to matched healthy subjects in order to reveal the impact of chronic intermittent hypoxia on the renin-angiotensin-aldosterone system. The patients that enrolled in this study were 19 OSAS patients who had undergone overnight polysomnography and had an Apnoea Hypopnoea Index (AHI) greater than 10 events/hour. They were compared to 20 healthy non-OSAS closely matched controls. Serum aldosterone and direct renin concentration were measured by radioimmunoassay. Aldosterone concentration follows a diurnal variation; therefore, all blood samples were obtained at the same time (6 AM). There were no significant differences in serum aldosterone levels between the two studied groups of OSAS patients and the healthy subjects group (140.6 pg/ml ± 25.2 vs. 133.2 pg/ml ± 18.5 with p = 0.223). Similar were the results for the renin levels (25.0 ± 6.9 vs. 24.9 ± 4.4 with p = 0.360). Our study suggests that patients with OSAS, but without existing hypertension have aldosterone and renin levels similar to healthy subjects. According to our findings a direct connection between OSAS and the development of arterial hypertension may not be established via sympathetic system activation.

Children with Down syndrome are at increased risk of obstructive sleep apnea (OSA). The aim of the study was to describe the management of OSA in a large cohort of children with Down syndrome. A retrospective analysis of sleep studies and consequent management was performed for all consecutive Down syndrome patients evaluated between September 2013 and April 2016. The data of 57 patients were analyzed: 51/53 had an interpretable overnight polygraphy and 4 the recording of nocturnal gas exchange. Mean age at baseline sleep study was 6.2 ± 5.9 years. Eighteen patients (32%) had prior upper airway surgery. Mean apnea-hypopnea index (AHI) was 14 ± 16 events/hr with 41 of the 51 (80%) patients having OSA with an AHI >1 event/hr and 20 patients (39%) having an AHI ≥10 events/hr. Consequently, eight patients (14%) had upper airway surgery. OSA improved in all patients except two who needed noninvasive respiratory support. Nineteen (33%) patients required noninvasive respiratory support. Mean age at noninvasive respiratory support initiation was 7 ± 7 years. On 11 patients with objective adherence data available, mean compliance at 2 ± 1 years of treatment was excellent with an average use per night of 8 hr46 ± 3 hr59 and 9 patients using the noninvasive respiratory support >4 hr/night. Noninvasive respiratory support was associated with an improvement of nocturnal gas exchange. The prevalence of OSA is high in Down syndrome. Upper airway surgery is not always able to correct OSA. Noninvasive respiratory support represents then an effective treatment for OSA and good compliance may be achieved in a majority of patients. © 2017 Wiley Periodicals, Inc.

To investigate the inter-relation between high sensitivity C-reactive protein and glycated hemoglobin in prediction of risk of obstructive sleep apnea. We included all individuals participating in a check-up program at the Preventive Medicine Center of Hospital Israelita Albert Einstein in 2014. The Berlin questionnaire for risk of obstructive sleep apnea was used, and the high sensitivity C-reactive protein and glycated hemoglobin levels were evaluated. The sample included 7,115 participants (age 43.4±9.6 years, 24.4% women). The Berlin questionnaire showed changes in 434 (6.1%) individuals. This finding was associated with high sensitivity C-reactive protein and glycated hemoglobin levels (p<0.001). However, only the association between the Berlin questionnaire result and glycated hemoglobin remained significant in the adjusted multivariate analysis, for the traditional risk factors and for an additional model, including high-density lipoprotein cholesterol and triglycerides. The glycated hemoglobin, even below the threshold for diagnosis of diabetes, is independently associated with obstructive sleep apnea syndrome, even after adjustment for obesity and C-reactive protein. These findings suggest a possible pathophysiological link between changes in insulin resistance and obstructive sleep apnea syndrome, independently from obesity or low-grade inflammation.

AIM: To investigate the mechanisms of Lactobacillus plantarum (L. plantarum) action on gut barrier in preoperative and postoperative experimental obstructive jaundice in rats. METHODS: Forty rats were randomly divided into groups of sham-operation, bile duct ligation (BDL), BDL + L. plantarum, BDL + internal biliary drainage (IBD), and BDL + IBD + L. plantarum. Ten days after L. plantarum administration, blood and ileal samples were collected from the rats for morphological examination, and intestinal barrier function, liver function, intestinal oxidative stress and protein kinase C (PKC) activity measurement. The distribution and expression of the PKC and tight junction (TJ) proteins, such as occludin, zonula occludens-1, claudin-1, claudin-4, junction adhesion molecule-A and F-actin, were examined by confocal laser scanning microscopy, immunohistochemistry, Western blotting, real-time fluorescent quantitative polymerase chain reaction assay. RESULTS: L. plantarum administration substantially restored gut barrier, decreased enterocyte apoptosis, improved intestinal oxidative stress, promoted the activity and expression of protein kinase (BDL vs BDL + L. plantarum, 0.295 ± 0.007 vs 0.349 ± 0.003, P < 0.05; BDL + IBD vs BDL + IBD + L. plantarum, 0.407 ± 0.046 vs 0.465 ± 0.135, P < 0.05), and particularly enhanced the expression and phosphorylation of TJ proteins in the experimental obstructive jaundice (BDL vs BDL + L. plantarum, 0.266 ± 0.118 vs 0.326 ± 0.009, P < 0.05). The protective effect of L. plantarum was more prominent after internal biliary drainage ( BDL + IBD vs BDL + IBD + L. plantarum, 0.415 ± 0.105 vs 0.494 ± 0.145, P < 0.05). CONCLUSION: L. plantarum can decrease intestinal epithelial cell apoptosis, reduce oxidative stress, and prevent TJ disruption in biliary obstruction by activating the PKC pathway. PMID:22912548

Obstructive sleep apnoea syndrome (OSAS) is one of the most relevant chronic respiratory pathologies due to its high prevalence and impact in morbidity and mortality. In 2001, the Asociación Argentina de Medicina Respiratoria (AAMR) published the first Argentinean Consensus on Sleep-Related breathing Disorders. Since then, wide new scientific evidence has emerged, increasing significantly the knowledge about this pathology. According to this, the Sleep-Related breathing Disorders and Oxygen Therapy Section of the AAMR, decided to update its Consensus, developing this Practical Guidelines on Management of patients with OSAS. A working group was created with members belonging to the section, experts in OSAS. They extensively reviewed the literature and wrote these guidelines, orientated to practical resolution of clinical problems and giving answers to questions emerged from dealing with patients who suffer from this syndrome. The document defines OSAS and describes the diagnosis and severity criteria, as well as the risk factors, ways of presentation and epidemiology. Clinical consequences, mainly on cognition, cardiovascular system and metabolism are pointed out. Different diagnostic methods, with their indications and technical aspects for validation and interpretation are detailed. Finally, we describe therapeutic alternatives, as well as practical aspects of their implementation. The authors' aim was to generate an accessible tool for teaching and spreading the knowledge on these disorders, which have a great impact in public health.

Obstructive sleep apnea syndrome and hypertension: mechanism of the linkage and 24-h blood pressure control.

PubMed

Hypertensive patients with obstructive sleep apnea syndrome (OSAS) constitute a high-risk group for metabolic syndrome. OSAS directly induces negative intrathoracic pressure and decreases pulmonary stretch receptor stimulation, chemoreceptor stimulation, hypoxemia, hypercapnia and microarousal. These changes potentiate various risk factors, including the sympathetic nervous system, renin-angiotensin-aldosterone system and inflammation. Early detection and treatment of OSAS in asymptomatic hypertensive patients is essentially important to prevent hypertensive target organ damage and subsequent cardiovascular events. Continuous positive airway pressure (CPAP) therapy, a first-line treatment in hypertensive patients with moderate to severe OSAS, reduces ambulatory BP level, particularly during the sleep period, and midnight BP surge. However, individual differences in the BP-lowering effect of CPAP have been observed. OSAS hypertensive patients who do not tolerate CPAP remain at a high risk for cardiovascular disease because of negative intrathoracic pressure and need more aggressive antihypertensive treatment to achieve 24-h BP control with nocturnal BP <120/70 mm Hg.

Allergic rhinitis (AR) and obstructive sleep apnea syndrome (OSAS) are worldwide prevalent diseases. These diseases impair patient quality of life. The aim of this study was to investigate and compare the efficacy of treatment of AR on OSAS by objective and subjective methods. The study group was composed of 80 OSAS patients with AR between the ages of 30 and 50 years. The patients were admitted with the complaint of snoring, and they were asked about AR-related symptoms (nasal discharge, nasal itching, sneeze, and nasal obstruction). Daytime somnolence was measured by the Epworth sleepiness scale (ESS). Sleep parameters on polysomnography tests before and after treatment were compared, and the effects of different AR treatment protocols on sleep quality were evaluated. When pretreatment and posttreatment apnea-hypopnea index (AHI) values of the groups were compared, the most significant difference was observed in the nasal steroid (Ns) + antihistamine (Ah) group (p < 0.05). The ESS results were significantly decreased in the Ns and Ns + Ah groups after treatment (p < 0.05). AHI oxygen saturation <90% were significantly decreased in the Ns and Ns + Ah groups after treatment (p < 0.05). Nasal obstruction due to nasal congestion causes increases in airway resistance and can lead to development of OSAS. We concluded that treating AR with Ns has both positive effects on OSAS and daily activity. However, adding Ah to this treatment did not show improved effects compared with placebo treatment.

Small bowel obstruction (SBO) is common in adult surgical procedures, mainly due to postoperative adhesions. Acute SBO in adults without history of abdominal surgery, trauma or clinical hernia is less common and has various etiologies. Congenital band is an extremely rare cause. A 56-year-old man was admitted to our hospital with a two-day history of abdominal pain and bilious vomiting. He had no history of abdominal surgery or any other medical problems. A contrast-enhanced CT of the abdomen showed a distention of small bowel loops with transition point in the right hypochondrium. Distended loops of small bowel were located in the left side of the abdomen, whereas collapsed loops was located in the right side. The normal bowel wall enhancement was preserved. After initial treatment with intravenous fluid and nasogastric suction, he was operated. At laparoscopy a band obstructing the ileum was clearly observed. This anomalous band extending from gallbladder to transverse mesocolon caused a small window leading to internal herniation of the small bowel and obstruction. The band was coagulated and divided. Postoperative outcome was uneventful and the patient was discharged on the second postoperative day. There was no recurrence of symptoms on subsequent follow-up. Congenital peritoneal bands are not frequently encountered in surgical practice and these bands are often difficult to classify and define. Diagnosis of acute intestinal obstruction due to CPB must be included in the differential diagnosis in any patient with no history of abdominal surgery, trauma, clinical hernia, inflammatory bowel disease or peritoneal tuberculosis. Despite technological advances in radiology preoperative diagnosis remains difficult, however the diagnosis of SBO due to CPB must be considered in any patient with no history of abdominal surgery, Trauma or clinical hernia consulting for occlusive syndrome. The laparoscopic approach should be intended initially for its feasibility and

Computational fluid dynamics (CFD) analysis may quantify the severity of anatomical airway restriction in obstructive sleep apnea syndrome (OSAS) better than anatomical measurements alone. However, optimal CFD model endpoints to characterize or assess OSAS have not been determined. To model upper airway fluid dynamics using CFD and investigate the strength of correlation between various CFD endpoints, anatomical endpoints, and OSAS severity, in obese children with OSAS and controls. CFD models derived from magnetic resonance images were solved at subject-specific peak tidal inspiratory flow; pressure at the choanae was set by nasal resistance. Model endpoints included airway wall minimum pressure (Pmin), flow resistance in the pharynx (Rpharynx), and pressure drop from choanae to a minimum cross section where tonsils and adenoids constrict the pharynx (dPTAmax). Significance of endpoints was analyzed using paired comparisons (t-test or Wilcoxon signed rank test) and Spearman correlation. Fifteen subject pairs were analyzed. Rpharynx and dPTAmax were higher in OSAS than control and most significantly correlated to obstructive apnea-hypopnea index (oAHI), r = 0.48 and r = 0.49, respectively (P < 0.01). Airway minimum cross-sectional correlation to oAHI was weaker (r = −0.39); Pmin was not significantly correlated. CFD model endpoints based on pressure drops in the pharynx were more closely associated with the presence and severity of OSAS than pressures including nasal resistance, or anatomical endpoints. This study supports the usefulness of CFD to characterize anatomical restriction of the pharynx and as an additional tool to evaluate subjects with OSAS. PMID:24265282

Inadequate absorptive surface area poses a great challenge to the patients suffering a variety of intestinal diseases causing short bowel syndrome. To date, these patients are managed with total parenteral nutrition or intestinal transplantation. However, these carry significant morbidity and mortality. Currently, by emergence of tissue engineering, anticipations to utilize an alternative method to increase the intestinal absorptive surface area are increasing. In this paper, we will review the improvements made over time in attempting elongating the intestine with surgical techniques as well as using intestinal bioengineering. Performing sequential intestinal lengthening was the preliminary method applied in humans. However, these methods did not reach widespread use and has limited outcome. Subsequent experimental methods were developed utilizing scaffolds to regenerate intestinal tissue and organoids unit from the intestinal epithelium. Stem cells also have been studied and applied in all types of tissue engineering. Biomaterials were utilized as a structural support for naive cells to produce bio-engineered tissue that can achieve a near-normal anatomical structure. A promising novel approach is the elongation of the intestine with an acellular biologic scaffold to generate a neo-formed intestinal tissue that showed, for the first time, evidence of absorption in vivo. In the large intestine, studies are more focused on regeneration and engineering of sphincters and will be briefly reviewed. From the review of the existing literature, it can be concluded that significant progress has been achieved in these experimental methods but that these now need to be fully translated into a pre-clinical and clinical experimentation to become a future viable therapeutic option.

Craniofacial malformations including cleft lip and/or palate (CL/P) increase risk for obstructive sleep apnea (OSA). While 30% of CL/P occurs in the context of underlying genetic syndromes, few studies have investigated the prevalence of OSA in this high-risk group. This study aims to determine the incidence and risk factors of positive screening for OSA in this complex patient population. The Pediatric Sleep Questionnaire (PSQ) was prospectively administered to all patients cared for by the cleft lip and palate clinic at the Children's Hospital of Philadelphia between January 2011 and August 2013. The PSQ is a 22-item, validated screening tool for OSA with a sensitivity and specificity of 0.83 and 0.87 in detecting an apnea-hypopnea index (AHI) >5/hour in healthy children. The Fisher exact and Chi-square tests were used for purposes of comparison. 178 patients with syndromic CL/P completed the PSQ. Mean cohort age was 8.1 ± 4.4 years. Patients were predominately female (53.9%), Caucasian (78.1%), and had Veau Class II cleft (50.6%). Craniofacial syndromes included isolated Pierre Robin Sequence (PRS) (29.8%), 22q11.2 deletion syndrome (14.6%), Van der Woude syndrome (6.7%), and other rare genetic abnormalities (28.8%). The overall incidence of positive OSA screening was 32.0%. Males were at increased risk for positive OSA screening (P = 0.030), as were non-Caucasians (P = 0.044). Symptoms with the highest positive predictive value for OSA were "others comment on child appearing sleepy" (76.2%) and "stops breathing during the night" (75.0%). Notably, patients with 22q11.2 deletion syndrome were at highest risk for positive screens (50.0%, P = 0.042). Nearly a third of our patients with syndromic CL/P screened positively for OSA (32.0%), highlighting the importance of screening in this at-risk population. Future work will correlate screening results with polysomnograms to help validate these findings. Diagnostic, III. Copyright © 2014 British Association of

The basic research in the center includes: epidemic survey of OSAHS and snoring in a Beijing population, setting up the cephalometric and MRI standard of airway and surrounding structures for non-snoring Chinese, aetology exploring OSAHS from views of airway size, craniofacial form, neck circumference and genioglossus muscle activity. Clinically, different dental appliances were developed. The treatment effects of the oral appliances for OSAHS patients were evaluated quantitatively. Two and three dimension changes of the airway and surrounding structures, genioglossus muscle activity, as well as snoring loudness following mandible advancing and opening were studied. Besides, research was expended to OSAHS in children recently. Under the support of National Nature Science Foundation 7 PhD and 3 MS students have graduated. More than 60 papers were published domestically and abroad and two awards were received from the National Ministry of Education and Chinese Medical Association in the past 10 years. This paper is a review of the past and current situation of dental research on OSAHS in China.

The obstructive sleep apnoea syndrome (OSAS) results from a combination of structural and neuromotor factors; however, the relative contributions of these factors have not been studied during the important developmental phase of adolescence. We hypothesised that adenotonsillar volume (ATV), nasopharyngeal airway volume (NPAV), upper airway critical closing pressure (Pcrit) in the hypotonic and activated neuromotor states, upper airway electromyographic response to subatmospheric pressure and the ventilatory response to CO 2 during sleep would be major predictors of OSAS risk. 42 obese adolescents with OSAS and 37 weight-matched controls underwent upper airway MRI, measurements of Pcrit, genioglossal electromyography and ventilatory response to CO 2 during wakefulness and sleep. ATV, NPAV, activated and hypotonic Pcrit, genioglossal electromyography and ventilatory response to CO 2 during sleep were all associated with OSAS risk. Multivariate models adjusted for age, gender, body mass index and race indicated that ATV, NPAV and activated Pcrit each independently affected apnoea risk in adolescents; genioglossal electromyography was independently associated in a reduced sample. There was significant interaction between NPAV and activated Pcrit (p=0.021), with activated Pcrit more strongly associated with OSAS in adolescents with larger NPAVs and NPAV more strongly associated with OSAS in adolescents with more negative activated closing pressure. OSAS in adolescents is mediated by a combination of anatomic (ATV, NPAV) and neuromotor factors (activated Pcrit). This may have important implications for the management of OSAS in adolescents.

Obstruction of bile flow results in bacterial proliferation and mucosal injury in the small intestine that can lead to the translocation of bacteria across the epithelial barrier and systemic infection. These adverse effects of biliary obstruction can be inhibited by administration of bile acids. Here we show that the farnesoid X receptor (FXR), a nuclear receptor for bile acids, induces genes involved in enteroprotection and inhibits bacterial overgrowth and mucosal injury in ileum caused by bile duct ligation. Mice lacking FXR have increased ileal levels of bacteria and a compromised epithelial barrier. These findings reveal a central role for FXR in protecting the distal small intestine from bacterial invasion and suggest that FXR agonists may prevent epithelial deterioration and bacterial translocation in patients with impaired bile flow.

Aerophagia induced by the nasal obstruction on experimental animals.

The excessive accumulation of gas in the gastrointestinal tracts was invariably induced on experimental animals (mice, rats, guinea pigs, hamsters and rabbits) by simply obstructing nasal passages. The analysis of the gas showed the almost identical composition to the ambient air or flutus which was largely due to swallowed air. Also the numerous small foams were found on and underneath the epithelial lining of small intestine. The pathological evaluation was done both macroscopically and microscopically. Dying animals after nasal obstruction showed hemorrhagic and necrotic changes in the jejunum and ileum. This observation may cast some light to the pathogenesis of necrotizing enterocolitis in human neonatal.

Intestinal lymphangiectasia in the adult may be characterized as a disorder with dilated intestinal lacteals causing loss of lymph into the lumen of the small intestine and resultant hypoproteinemia, hypogammaglobulinemia, hypoalbuminemia and reduced number of circulating lymphocytes or lymphopenia. Most often, intestinal lymphangiectasia has been recorded in children, often in neonates, usually with other congenital abnormalities but initial definition in adults including the elderly has become increasingly more common. Shared clinical features with the pediatric population such as bilateral lower limb edema, sometimes with lymphedema, pleural effusion and chylous ascites may occur but these reflect the severe end of the clinical spectrum. In some, diarrhea occurs with steatorrhea along with increased fecal loss of protein, reflected in increased fecal alpha-1-antitrypsin levels, while others may present with iron deficiency anemia, sometimes associated with occult small intestinal bleeding. Most lymphangiectasia in adults detected in recent years, however, appears to have few or no clinical features of malabsorption. Diagnosis remains dependent on endoscopic changes confirmed by small bowel biopsy showing histological evidence of intestinal lymphangiectasia. In some, video capsule endoscopy and enteroscopy have revealed more extensive changes along the length of the small intestine. A critical diagnostic element in adults with lymphangiectasia is the exclusion of entities (e.g. malignancies including lymphoma) that might lead to obstruction of the lymphatic system and "secondary" changes in the small bowel biopsy. In addition, occult infectious (e.g. Whipple's disease from Tropheryma whipplei) or inflammatory disorders (e.g. Crohn's disease) may also present with profound changes in intestinal permeability and protein-losing enteropathy that also require exclusion.

A 66-year-old man presented at our emergency department with severe intermittent abdominal pain. His history revealed that he had eaten several mochi (rice cakes) without sufficiently chewing them before swallowing. Following computed tomography that showed a high value, he was diagnosed with an obstruction caused by mochi. Although mochi obstruction can sometimes improve with conservative treatment, this case required laparotomy. Medical literature in English on small bowel obstruction due to mochi is rare, but fortunately in this case we were able to collect complete laboratory and imaging data. Furthermore, due to the surgical findings, we could clearly diagnose the pathophysiology of mochi obstruction. Here we describe a case of small bowel obstruction due to mochi, and review the literature to determine the characteristics of intestinal obstruction caused by it.

Intestinal malrotation in the newborn is usually diagnosed after signs of intestinal obstruction, such as bilious emesis, and corrected with the Ladd procedure. The objective of this report is to describe the presentation of severe cases of midgut volvulus presenting in infancy, and to discuss the characteristics of these cases. We performed a 7-year review at our institution and present two cases of catastrophic midgut volvulus presenting in the post-neonatal period, ending in death soon after the onset of symptoms. These two patients also had significant laboratory abnormalities compared to patients with more typical presentations resulting in favorable outcomes. Although most cases of intestinal malrotation in infancy can be treated successfully, in some circumstances, patients' symptoms may not be detected early enough for effective treatment, and therefore may result in catastrophic midgut volvulus and death.

We investigated endothelial dysfunction, an early manifestation of atherosclerosis, in patients with mild obstructive sleep apnea syndrome (OSAS) (5/h < AHI < 15/h). Endothelium-dependent and -independent vasodilatory function was tested in 10 patients with mild OSAS, 12 healthy controls and 20 subjects with moderate to severe OSAS using the hand vein compliance technique. Maximum endothelium-dependent vasodilation to bradykinin (Emax) was significantly blunted in patients with mild OSAS (68.6 +/- 30.2 %) compared to healthy controls (94.8 +/- 9.5 %; p < 0.05; moderate to severe OSAS: 57.1 +/- 23.4 %; p = 0.33). Mean endothelium-independent venodilation was not altered. After 160.7 +/- 82.2 nights of CPAP therapy, mean Emax was significantly improved to 90.8 +/- 23.8 % (p < 0.01 vs. baseline; p = 0.7 vs. healthy controls) in 7 patients with mild OSAS. Systemic endothelium-dependent venodilation is markedly reduced in subjects with mild OSAS, which may imply adverse cardiovascular consequences. CPAP-treatment leads to a sustained restoration of endothelial dysfunction in these patients and is thus highly recommended.

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a well-recognized clinical sleep disorder that results in chronically fragmented sleep and recurrent hypoxemia. The primary daytime sequelae of the disorder include patient reports of excessive daytime sleepiness, depression, and attention and concentration problems. It has been well established that OSAHS negatively impacts certain aspects of cognitive functioning. The primary goals of this article are to (1) clarify the pattern of cognitive deficits that are specific to OSAHS; (2) identify the specific cognitive domains that improve with treatment; and (3) elucidate the possible mechanisms of cognitive dysfunction in OSAHS. At the conclusion of the paper, we propose a potential neurofunctional theory to account for the etiology of cognitive deficits in OSAHS. Thirty-seven peer-reviewed articles were selected for this review. In general, findings were equivocal for most cognitive domains. Treatment, however, was noted to improve attention/vigilance in most studies and consistently did not improve constructional abilities or psychomotor functioning. The results are discussed in the context of a neurofunctional theory for the effects of OSAHS on the brain.

Obstructive Sleep Apnea Syndrome (OSAS) Increases Pedestrian Injury Risk in Children

Objectives To evaluate pedestrian behavior, including reaction time, impulsivity, risk-taking, attention, and decision-making, in children with obstructive sleep apnea syndrome (OSAS) compared with healthy controls. Study design Using a case control design, sixty 8- to 16-year-olds with newly diagnosed and untreated OSAS engaged in a virtual reality pedestrian environment. Sixty-one healthy children matched using a yoke-control procedure by age, race, gender and household income served as controls. Results Children with OSAS were riskier pedestrians than healthy children of the same age, race, and sex. Children with OSAS waited less time to cross (p<.01). The groups did not differ in looking at oncoming traffic or taking longer to decide to cross. Conclusions Results suggest OSAS may have significant consequences on children’s daytime functioning in a critical domain of personal safety, pedestrian skills. Children with OSAS appeared to have greater impulsivity when crossing streets. Results highlight the need for heightened awareness of the consequences of untreated sleep disorders and identify a possible target for pediatric injury prevention. PMID:25444002

Sleep-related painful erection (SRPE) is a rare sleep disorder characterized by recurrent, painful penile erections occurring when awakening from rapid eye movement sleep, while erections are painless during wakefulness. Almost 35 cases have been reported worldwide, and only two of them had an associated obstructive sleep apnea syndrome (OSAS). We report a new case of a 61-year-old man suffering from SRPE associated with OSAS. The adequate treatment of respiratory events with continuous positive airway pressure did not alleviate the SRPE symptoms and excessive daytime sleepiness. The SRPE diagnosis was made by polysomnography coupled with video surveillance when the patient was referred to the sleep laboratory for residual excessive daytime sleepiness. The patient had 2-4 episodes of SRPE/night. Beta-blocker did not alleviate the SRPE, but a transient improvement was noted when the patient was treated with paroxetine. In contrast with the two previously published cases of SRPE plus OSAS, continuous positive airway treatment did not improve SRPE symptoms in our patient.

Microparticles are deemed true biomarkers and vectors of biological information between cells. Depending on their origin, the composition of microparticles varies and the subsequent message transported by them, such as proteins, mRNA, or miRNA, can differ. In obstructive sleep apnea syndrome (OSAS), circulating microparticles are associated with endothelial dysfunction by reducing endothelial-derived nitric oxide production. Here, we have analyzed the potential role of circulating microparticles from OSAS patients on the regulation of angiogenesis and the involved pathway. VEGF content carried by circulating microparticles from OSAS patients was increased when compared with microparticles from non-OSAS patients. Circulating microparticles from OSAS patients induced an increase of angiogenesis that was abolished in the presence of the antagonist of endothelin-1 receptor type B. In addition, endothelin-1 secretion was increased in human endothelial cells treated by OSAS microparticles. We highlight that circulating microparticles from OSAS patients can modify the secretome of endothelial cells leading to angiogenesis. Copyright © 2013 Elsevier B.V. All rights reserved.

Alternatives to CPAP in the treatment of the obstructive sleep apnea syndrome.

PubMed

Bloch, Konrad E

2006-04-29

The obstructive sleep apnoea syndrome (OSAS) results in excessive daytime sleepiness, impaired quality of life, and is associated with an increased risk of traffic accidents and cardiovascular disease. Nasal continuous positive airway pressure (CPAP), the standard treatment for OSAS provides immediate relief of symptoms and has only minor side effects. Nevertheless, an alternative treatment is needed if CPAP is not feasible for medical or psychological reasons. Removable oral appliances that advance the mandible when fitted to the teeth during sleep also improve nocturnal breathing disturbances, symptoms, quality of life, vigilance and blood pressure in OSAS patients. Their long-term effectiveness and side effects require further study. In morbidly obese patients suffering from OSAS bariatric surgery should be considered as a treatment that reduces obesity and at the same time improves OSAS. In selected patients including those with adeno-tonsillar hypertrophy, and cranio-facial malformations various surgical techniques that enlarge the upper airway may be a treatment option for OSAS.

We report a patient with severe obstructive sleep apnea syndrome, diabetes mellitus, and hypertension, with postoperative complications following tracheostomy. His stormy postoperative course is presented with emphasis on glycemic control and hypertension. We present a cautionary tale of a significant reduction in medications to control blood pressure and hyperglycemia following tracheostomy for severe OSA. The severe reduction in blood pressure and hypoglycemia could mimic sepsis and clinicans need to be vigilant to these dramatic effects following tracheostomy and appropriately adjust baseline medications.

Duodenal obstruction caused by ileocolic intussusception in the absence of intestinal malrotation is extremely rare. We present and discuss the imaging findings in an infant with an intussusception secondary to a duplication cyst in whom sonography also showed inversion of the orientation of the mesenteric vessels and a distended stomach. A contrast medium study revealed a proximal duodenal obstruction with a beak appearance suggestive of midgut volvulus. At surgery, an ileocolic intussusception causing duodenal obstruction without concomitant malrotation or volvulus was found. The combination of duodenal obstruction and abnormal relationship of the mesenteric vessels as a result of ileocolic intussusception has not previously been reported in the literature.

Fecal impaction if left untreated can lead to the hardening of stools and the formation of fecalith. Fecaliths rarely cause serious complications and are usually managed conservatively. We present this rare case of a giant fecalith causing near obstruction in an institutionalized paraplegic patient at high risk for chronic constipation and fecal impaction. This case was also unusual for causing ischemic pressure necrosis in the rectum, thereby highlighting the possible serious complications of fecalith. PMID:28611554

To determine factors that may predict intestinal pseudo-obstruction (IpsO) in systemic lupus erythematosus (SLE) patients complicated by digestive manifestations. SLE patients with digestive manifestations (n = 135) were followed at Southern Medical University affiliated Nanfang Hospital from 2000 until 2013. Demographic variables, clinical features, and laboratory data were compared between the two groups. Univariate and multivariate logistic regression models were used to establish factors that predispose to IpsO in these patients. At the end of the study period, 32 (23.7%) patients had developed IpsO. Mortality (9 patients) was infrequent and the cause of death was unrelated to IpsO. Independent predictors of IpsO in SLE were ureterectasia, anti-U1 RNP(+), peritonitis, and low C3 levels. Regular abdominal X-ray examinations are recommended in SLE patients with ureterectasia, anti-U1 RNP(+), peritonitis, or low C3 levels, as early diagnosis and therapy may prevent unnecessary surgical intervention and improve the disease course. © The Author(s) 2015.

Congenital obstruction of the left ventricular outflow tract remains a significant problem and multilevel obstruction can often coexist. Obstruction can take several morphological forms and may involve the subvalvar, valvar or supravalvar portion of the aortic valve complex. Congenital valvar stenosis presenting in the neonatal period represents a spectrum of disorders ranging from the hypoplastic left heart syndrome to almost normal hearts. Treatment options vary dependent on the severity of the left ventricular outflow tract obstruction (LVOTO) and the variable degree of left ventricular hypoplasia as well as the associated lesions such as arch hypoplasia and coarctation.

Human endocrine-cerebro-osteodysplasia (ECO) syndrome, caused by the loss-of-function mutation R272Q in the ICK (intestinal cell kinase) gene, is a neonatal-lethal developmental disorder. To elucidate the molecular basis of ECO syndrome, we constructed an Ick R272Q knock-in mouse model that recapitulates ECO pathological phenotypes. Newborns bearing Ick R272Q homozygous mutations die at birth due to respiratory distress. Ick mutant lungs exhibit not only impaired branching morphogenesis associated with reduced mesenchymal proliferation, but also significant airspace deficiency in primitive alveoli concomitant with abnormal interstitial mesenchymal differentiation. ICK dysfunction induces elongated primary cilia and perturbs ciliary Hedgehog signaling and autophagy during lung sacculation. Our study identifies an essential role for ICK in lung development and advances the mechanistic understanding of ECO syndrome. PMID:28380258

The aim of this study was to understand the role of enterocele in the pathogenesis of the obstructed defecation syndrome (ODS) a new defecographic classification based on function. A total of 597 patients (551 women, 46 men) who underwent cinedefecography between November 2001 and November 2005 were studied. A total of 567 (95%) underwent cinedefecography as they had symptoms of ODS. Enterocele was classified into three types. Enterocele was found in 127 (23%) female and one (2.2%) male patients. Thirty-eight (6.9%) patients had type A, 38(6.9%) type B, and 27(4.9%) type C enterocele. A total of 24 patients (4.35%) had sigmoidocele. In patients with type C enterocele, the finding of a radiological pattern of ODS was higher (26/27) than that in the other groups (A + B + Sigmoidocele) (23/100) (P < 0.001). An obstructed evacuation pattern was found in 49 (38.5%) patients with enterocele and in 148 (34.9%) patients in the control group. Type C enterocele is often associated with a radiological pattern of ODS and usually presents as an isolated condition. Type B is less frequently associated with ODS and is more frequently accompanied by other pathological conditions.

Diffuse disturbance in gastrointestinal motility may be present in patients with irritable bowel syndrome (IBS). To further investigate small intestinal motility in IBS patients small intestinal transit time (SITT) was determined and related to the symptom status. 11 female patients with IBS (mean age 29 years) were divided into those whose predominate symptom was diarrhea (N=6), and those with only constipation (N=5). All subjects ingested an isosmotic solution of lactulose (10 gm in 150cc of water) labeled with 99m-Tc-DTPA (Sn). The patient was studied supine under a 25 inch gamma camera with data collected at 1 frame per minute formore » 180 minutes or until activity appeared in the ascending colon. Regions of interest were selected over the cecum and ascending colon. The time of first appearance of radioactivity in the region of the cecum was taken as the small intestinal transit time. SITT in the 5 normal females was 98.7 +- 13 min (mean +- SEM). SITT in the IBS patients with diarrhea, 67.3 +- 7 min was significantly faster (p< 0.08). SITT in the constipated IBS patients, 126 +- 12 min, was slower than normals and significantly different from diarrhea patients (p< 0.001). These studies show that IBS patients with diarrhea have significantly faster SITT than normals while constipated IBS patients have significantly slower SITT than the diarrhea subgroup. Further, this study emphasizes the need to study the various symptomatic subgroups of IBs patients independently and indicates a possible role for abnormal SITT in the pathogenesis of IBS.« less

To establish the diagnostic test accuracy of both two-dimensional (2D) and four-dimensional (4D) transperineal ultrasound, to assess if 4D ultrasound imaging provides additional value in the diagnosis of posterior pelvic floor disorders in women with obstructed defaecation syndrome. In this prospective cohort study, 121 consecutive women with obstructed defaecation syndrome were recruited. Symptoms of obstructed defaecation and signs of pelvic organ prolapse were assessed using validated methods. All women underwent both 2D transperineal ultrasound (Pro-focus, 8802 transducer, BK-medical) and 4D transperineal ultrasound (Voluson i, RAB4-8-RS transducer, GE). Imaging analysis was performed by two blinded observers. Pelvic floor disorders were dichotomised into presence or absence according pre-defined cut-off values. In the absence of a reference standard a composite reference standard was created from a combination of results of evacuation proctogram, magnetic resonance imaging and endovaginal ultrasound. Primary outcome measures were diagnostic test characteristics of 2D and 4D transperineal ultrasound for diagnosis or rectocele, enterocele, intussusception and anismus. Secondary outcome measures were interobserver agreement, agreement between the two techniques and correlation of signs and symptoms to imaging findings. For diagnosis of all four posterior pelvic floor disorders there was no difference in sensitivity and specificity between 2D and 4D TPUS (p= 0.131 - 1.000). A good agreement between 2D and 4D TPUS was found for the diagnosis of rectocele (ĸ 0.675) and a moderate agreement for diagnosis of enterocele, intussusception and anismus (ĸ 0.465 - 0.545). There was no difference in rectocele depth measurements between both TPUS techniques (19.9 mm vs 19.0 mm, p=0.802). Inter-observer agreement was comparable for both techniques, however 2D TPUS had an excellent interobserver agreement for diagnosis of enterocele and rectocele depth measurements. Diagnosis

Cytomegalovirus is the most common cause of congenital infection in the developed countries. Gastrointestinal involvement has been extensively described in both adult and paediatric immunocompromised patients but it is infrequent in congenital or perinatal CMV infection. We report on a case of coexistent congenital Cytomegalovirus infection with intestinal malrotation and positive intestinal Cytomegalovirus biopsy. At birth the neonate showed clinical and radiological evidence of intestinal obstruction. Meconium passed only after evacuative nursing procedures; stooling pattern was irregular; gastric residuals were bile-stained. Laparatomy revealed a complete intestinal malrotation and contextually gastrointestinal biopsy samples of the appendix confirmed the diagnosis of CMV gastrointestinal disease. Intravenous ganciclovir was initiated for 2 weeks, followed by oral valgancyclovir for 6 month. CMV-induced proinflammatory process may be responsible of the interruption of the normal development of the gut or could in turn lead to a disruption in the normal development of the gut potentiating the mechanism causing malrotation. We suggest the hypothesis that an inflammatory process induced by CMV congenital infection may be responsible, in the early gestation, of the intestinal end-organ disease, as the intestinal malrotation. CMV infection should always be excluded in full-term infants presenting with colonic stricture or malrotation.

Sinusoidal Obstruction Syndrome (Hepatic Veno-Occlusive Disease)

PubMed Central

Fan, Cathy Q.; Crawford, James M.

2014-01-01

Hepatic sinusoidal obstruction syndrome (SOS) is an obliterative venulitis of the terminal hepatic venules, which in its more severe forms imparts a high risk of mortality. SOS, also known as veno-occlusive disease (VOD), occurs as a result of cytoreductive therapy prior to hematopoietic stem cell transplantation (HSCT), following oxaliplatin-containing adjuvant or neoadjuvant chemotherapy for colorectal carcinoma metastatic to the liver and treated by partial hepatectomy, in patients taking pyrrolizidine alkaloid-containing herbal remedies, and in other particular settings such as the autosomal recessive condition of veno-occlusive disease with immunodeficiency (VODI). A central pathogenic event is toxic destruction of hepatic sinusoidal endothelial cells (SEC), with sloughing and downstream occlusion of terminal hepatic venules. Contributing factors are SEC glutathione depletion, nitric oxide depletion, increased intrahepatic expression of matrix metalloproteinases and vascular endothelial growth factor (VEGF), and activation of clotting factors. The clinical presentation of SOS includes jaundice, development of right upper-quadrant pain and tender hepatomegaly, ascites, and unexplained weight gain. Owing to the potentially critical condition of these patients, transjugular biopsy may be the preferred route for liver biopsy to exclude other potential causes of liver dysfunction and to establish a diagnosis of SOS. Treatment includes rigorous fluid management so as to avoid excessive fluid overload while avoiding too rapid diuresis or pericentesis, potential use of pharmaceutics such as defibrotide, coagulolytic agents, or methylprednisolone, and liver transplantation. Proposed strategies for prevention and prophylaxis include reduced-intensity conditioning radiation for HSCT, treatment with ursodeoxycholic acid, and inclusion of bevacizumab with oxaliplatin-based chemotherapeutic regimes. While significant progress has been made in understanding the pathogenesis

2016-11-01

A 46-year-old Chinese woman with a history of cholecystectomy and appendicectomy presented to the emergency department with symptoms of intestinal obstruction. Physical examination revealed central abdominal tenderness but no clinical features of peritonism. Plain radiography of the abdomen revealed a grossly distended large bowel loop with the long axis extending from the right lower abdomen toward the epigastrium, and an intraluminal air-fluid level. These findings were suspicious for an acute caecal volvulus, which was confirmed on subsequent contrast-enhanced computed tomography (CT) of the abdomen and pelvis. CT demonstrated an abnormal positional relationship between the superior mesenteric vein and artery, indicative of an underlying intestinal malrotation. This case highlights the utility of preoperative imaging in establishing the diagnosis of an uncommon cause of bowel obstruction. It also shows the importance of recognising the characteristic imaging features early, so as to ensure appropriate and expedient management, thus reducing patient morbidity arising from complications.

Abstract Background: The constellation of metabolic syndrome, although controversial with regard to its clinical usefulness, is epidemiologically related to increased diabetes risk and cardiovascular mortality. Our goal was to investigate the associations among neck circumference (NC), obstructive sleep apnea syndromes (OSAS), and metabolic syndrome in obese men and women sleeping less than 6.5 hr per night. Methods: This was a cross-sectional study of obese men and premenopausal obese women sleeping less than 6.5 hr per night. We enrolled 120 individuals (92 women), age 40.5±6.9 years and body mass index (BMI) 38.6±6.5 kg/m2. Metabolic syndrome severity was assessed by a score and OSAS was defined as a respiratory disturbance index (RDI) ≥5. Metabolic end endocrine parameters were measured, and sleep duration was determined by actigraphy and validated questionnaires. Results: Metabolic syndrome was found in 41% and OSAS in 58% (28% had both). Subjects with metabolic syndrome were 3 years older and more often Caucasian; they had higher RDI scores, larger NC, more visceral fat, lower serum adiponectin, higher 24-hr urinary norepinephrine (NE) excretion, and lower growth hormone concentrations. A NC of ≥38 cm had a sensitivity of 54% and 58% and a specificity of 70% and 79% in predicting the presence of metabolic syndrome and OSAS, respectively. RDI, adiponectin, and NC accounted for approximately 30% of the variability in the metabolic syndrome score, as estimated by an age-, gender-, and race-corrected multivariate model (R2=0.376, P<0.001). Conclusion: Greater NC is associated with OSAS and metabolic syndrome in short-sleeping obese men and premenopausal obese women. Addition of NC to the definition of metabolic syndrome should be considered and needs to be validated in future studies. PMID:24571423

Successful treatment of a 14-year-old patient with intestinal malrotation with laparoscopic Ladd procedure: case report and literature review

PubMed Central

2013-01-01

Midgut malrotation is an anomaly of intestinal rotation that occurs during fetal development and usually presents in the neonatal period. We present a rare case of malrotation in a 14-year-old patient who presented with cramping, generalized right abdominal pain, and vomiting for a duration of one day. A computed tomography abdominal scan and upper gastrointestinal contrast studies showed malrotation of the small bowel without volvulus. Laparoscopy revealed typical Ladd’s bands and a distended flabby third and fourth duodenal portion extrinsically obstructing the misplaced duodeno-jejunal junction. The Ladd procedure, including widening of the mesenteric base and appendectomy, was performed. Symptoms completely resolved in a half-year follow up period. Patients with midgut malrotation may present with vague abdominal pain, intestinal obstruction, or intestinal ischemia. The laparoscopic Ladd procedure is feasible and safe, and it appears to be as effective as the standard open Ladd procedure in the diagnosis and treatment of teenage or adult patients with intestinal malrotation.

Severe short bowel syndrome (SBS) is a major cause of chronic (Type 3) intestinal failure (IF) where structural and functional changes contribute to malabsorption and risk of micronutrient deficiencies. Chronic IF may be reversible, depending on anatomy and intestinal adaptation, but most patients require long-term nutritional support, generally in the form of parenteral nutrition (PN). SBS management begins with dietary changes and pharmacologic therapies taking into account individual anatomy and physiology, but these are rarely sufficient to avoid PN. New hormonal therapies targeting intestinal adaptation hold promise. Surgical options for SBS including intestinal transplant are available, but have significant limitations. Home PN (HPN) is therefore the mainstay of treatment for severe SBS. HPN involves chronic administration of macronutrients, micronutrients, fluid, and electrolytes via central venous access in the patient's home. HPN requires careful clinical and biochemical monitoring. Main complications of HPN are related to venous access (infection, thrombosis) and metabolic complications including intestinal failure associated liver disease (IFALD). Although HPN significantly impacts quality of life, outcomes are generally good and survival is mostly determined by the underlying disease. As chronic intestinal failure is a rare disease, registries are a promising strategy for studying HPN patients to improve outcomes.

Untreated chronic obstructive pulmonary disease (COPD) co-existing with obstructive sleep apnea (OSA), also known as overlap syndrome, has higher cardiovascular mortality than COPD alone but its underlying mechanism remains unclear. We hypothesize that the presence of overlap syndrome is associated with more extensive right ventricular (RV) remodeling compared to patients with COPD alone. Adult COPD patients (GOLD stage 2 or higher) with at least 10 pack-years of smoking history were included. Overnight laboratory-based polysomnography was performed to test for OSA. Subjects with an apnea-hypopnea index (AHI) >10/h were classified as having overlap syndrome (n = 7), else classified as having COPD-only (n = 11). A cardiac MRI was performed to assess right and left cardiac chambers sizes, ventricular masses, and cine function. RV mass index (RVMI) was markedly higher in the overlap group than the COPD-only group (19 ± 6 versus 11 ± 6; p = 0.02). Overlap syndrome subjects had a reduced RV remodeling index (defined as the ratio between RVMI and RV end-diastolic volume index) compared to the COPD-only group (0.27 ± 0.06 versus 0.18 ± 0.08; p = 0.02). In the overlap syndrome subjects, the extent of RV remodeling was associated with severity of oxygen desaturation (R(2) = 0.65, p = 0.03). Our pilot results suggest that untreated overlap syndrome may cause more extensive RV remodeling than COPD alone.

A one-year-old male Golden Retriever presented with acute onset of vomiting and hemorrhagic diarrhea since 2 days. The dog was depressed, showing abdominal pain, 12% dehydration, tachycardia, and a bounding pulse. Diagnostic imaging showed severe dilatation and fluid retention of the entire gastrointestinal tract with decreased motility. A foreign body was found in the gastroduodenal region, but there was no obstruction or plication. The dog was tentatively diagnosed with acute hemorrhagic diarrhea syndrome and rapidly recovered after supportive treatment. However, on the morning of day 4, anorexia and vomiting recurred, and diagnostic imaging revealed intestinal plication with free peritoneal fluid, not found on the previous image. An emergency laparotomy revealed the foreign body to be two used feminine hygiene products. These contaminated products were suspected to induce acute hemorrhagic diarrhea syndrome, and led to subsequent complication in this large dog.

A Pneumocystis jiroveci infection-associated mass clinically mimicking a malignancy (ie, pseudotumor) is rare and usually occurs in the lung in association with Pneumocystis pneumonia. Pneumocystis jiroveci pseudotumors of the small intestine are extremely rare and represent an unusual form of disseminated P jiroveci infection. We present a case of small-intestine P jiroveci pseudotumor as an acquired immunodeficiency syndrome-presenting illness in a patient with coinfection with cytomegalovirus, no pulmonary symptoms, and no known risk factors for human immunodeficiency virus infection. This case reinforces the potential importance of cytomegalovirus coinfection in the disseminated form of Pneumocystis infection and illustrates the importance of an expanded differential diagnosis when confronted with a clinically atypical mass lesion.

Human endocrine-cerebro-osteodysplasia (ECO) syndrome, caused by the loss-of-function mutation R272Q in the intestinal cell kinase (ICK) gene, is a neonatal-lethal developmental disorder. To elucidate the molecular basis of ECO syndrome, we constructed an Ick R272Q knock-in mouse model that recapitulates ECO pathological phenotypes. Newborns bearing Ick R272Q homozygous mutations die at birth due to respiratory distress. Ick mutant lungs exhibit not only impaired branching morphogenesis associated with reduced mesenchymal proliferation but also significant airspace deficiency in primitive alveoli concomitant with abnormal interstitial mesenchymal differentiation. ICK dysfunction induces elongated primary cilia and perturbs ciliary Hedgehog signaling and autophagy during lung sacculation. Our study identifies an essential role for ICK in lung development and advances the mechanistic understanding of ECO syndrome. © 2017 Federation of European Biochemical Societies.

There is growing evidence that leptin regulation is altered in obstructive sleep apnea syndrome (OSAS). Several potential mechanisms have been purported to explain how sleep apnea may alter leptin levels. We investigated whether repeated apneas, hypoxia, or excessive daytime sleepiness influenced the levels of leptin in OSAS patients. We also evaluated whether a 3-month continuous positive airway pressure (CPAP) treatment affected leptin levels in patients. Randomly selected 31 untreated, otherwise healthy male, overweight [body mass index (BMI) >25 kg/m(2)] obstructive sleep apnea syndrome (OSAS) patients [apnea-hypopnea index (AHI) ≥15] and 25 control (AHI <5) were included in this study. To confirm the diagnosis, all subjects underwent standard polysomnography. Serum samples were taken at 07:00-08:00 a.m. after overnight fasting. The OSAS patients that had regular CPAP treatment (n=26) were re-evaulated 3 months later. Leptin levels (50.5±17.5 grams/L in OSAS and 56.3±25.5 grams/L in controls) and lipid profiles (TC, TGs, HDL-C, and LDL-C) between patient and control groups did not differ (P>0.05). Leptin levels were not correlated with the AHI, oxygen saturation, or excessive daytime sleepiness. CPAP treatment did not significantly change the (BMI), waist and neck circumference, or leptin levels in OSAS patients. Furthermore, we found no correlation between the decrease in serum leptin levels and parameters that were improved by CPAP treatment. Leptin levels and lipid profile of overweight subjects with and without OSAS were not different, and our results suggest that OSAS-related parameters and CPAP treatment do not play a significant role in the serum leptin levels.

In order to investigate the properties of somatostatin-14 we studied an experimental model of simple mechanical and closed loop occlusion. Forty-eight New Zealand rabbits were assigned randomly to three groups of 16: group C (controls) was operated and treated with saline solution (4 cc/Kg/h); group A was operated and initially treated with saline solution and an equal dose of somatostatin-14 (3.5 micrograms/Kg/h; and group B was operated and treated in the same manner as group A, but later, 8 hours after the laparotomy. The animals were sacrificed 24 hours later; intestinal secretion was quantified, blood and intestinal fluid chemistries were performed and specimens of the intestine were prepared for histological examination. Descriptive statistical analysis of the results was performed with the ANOVA, a semi-quantitative test and the covariance test. Somatostatin-14 produced an improvement in the volume of intestinal secretion in the treated groups compared with the control group. The results were statistically significant in group B treated after an 8-hour delay: closed loop (ml): 6.40 +/- 1.12, 2.50 +/- 0.94, 1.85 +/- 0.83 and simple mechanical occlusion (ml): 175 +/- 33.05, 89.50 +/- 9.27, 57.18 +/- 21.23, p < 0.01 for groups C, A and B C, A and B respectively. Net secretion of Cl and Na ions was also improved, p < 0.01.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a 16-year-old pubescent pediatric patient with obstructive sleep apnea syndrome (OSAS) and short stature whose apnea hypopnea index (AHI) was significantly reduced following the use of an orthodontic oral appliance that advances the mandible ventrally. The mandible was advanced 64% of the maximal mandibular protrusive position with use of the appliance over a 3-year period. The patient's AHI without the appliance in place decreased from 101.6/h at baseline to 11/h after treatment. Moreover, the patient's height increased 14 cm during treatment, resulting in height close to the average height for his age. Cephalometric analysis revealed an improvement in his retrognathic mandible and proclination of the upper front teeth. In conclusion, an orthodontic mandibular advancement oral appliance played an important role not only in improving the patient's OSAS but also in normalizing his physical growth during puberty.

Neuronal Intestinal Dysplasia type B (NID B) is a complex alteration of the enteric nervous system belonging to the group of intestinal dysganglionoses which may involve rectum, colon, and small intestine. Second only to Hirschsprung diseases (HSCR), NID B is one of the most frequent causes of chronic constipation and pseudo-obstructive intestinal dysmotility. Since NID B is often associated with HSCR and point mutations in the RET proto-oncogene have been identified in HSCR patients, we analyzed two NID B pedigrees to investigate if RET mutations might cause also the NID B phenotype. Linkage analysis demonstrated that the NID B locusmore » is not linked to RET in the pedigrees analysed. Further genetic analyses will possibility improve the understanding of the cause and facilitate diagnostic procedures in NID B. 20 refs., 1 fig., 2 tabs.« less

The obstructive sleep apnea syndrome (OSAS) involves recurrent sleep-related upper airways (UA) collapse. UA mechanical properties and neural control are altered, imposing a mechanical load on inspiration. UA collapse does not occur during wakefulness, hence arousal-dependent compensation. Experimental inspiratory loading in normal subjects elicits respiratory-related cortical activity. The objective of this study was to test whether awake OSAS patients would exhibit a similar cortical activity. Descriptive physiology study. Sleep laboratory in a large university affiliated tertiary hospital. 26 patients with moderate OSAS according to polysomnography (5 < apnea-hypopnea index [AHI] ≤ 30, n = 14) or severe OSAS (AHI > 30, n = 12); 13 non-OSAS patients for comparison. None. Respiratory time-locked electroencephalographic segments ensemble averaged and analyzed for slow premotor potentials preceding inspiration ("pre-inspiratory potentials" [PIPs]). PIPs were present in 1/13 controls and 11/26 patients (P = 0.0336; 4/14 "moderate" and 7/12 "severe" patients). Awake OSAS patients therefore exhibit respiratory-related cortical activity during quiet breathing significantly more frequently than non-OSAS individuals. The corresponding PIPs resemble those observed during prepared voluntary inspirations and in response to experimental inspiratory loads in normal subjects, which involve a cortical network comprising the supplementary motor area. A respiratory-related cortical activity could contribute to the increased neural drive to upper airway and to inspiratory muscles that has previously been described in obstructive sleep apnea, and could therefore contribute to the arousal-dependent compensation of upper airway abnormalities. Whether or not such cortical compensatory mechanisms have cognitive consequences remains to be determined. © 2015 Associated Professional Sleep Societies, LLC.

We have limited knowledge about the association between the composition of the intestinal microbiota and clinical features of irritable bowel syndrome (IBS). We collected information on the fecal and mucosa-associated microbiota of patients with IBS and evaluated whether these were associated with symptoms. We collected fecal and mucosal samples from adult patients who met the Rome III criteria for IBS at a secondary/tertiary care outpatient clinics in Sweden, as well as from healthy subjects. The exploratory set comprised 149 subjects (110 with IBS and 39 healthy subjects); 232 fecal samples and 59 mucosal biopsy samples were collected and analyzed by 16S ribosomal RNA targeted pyrosequencing. The validation set comprised 46 subjects (29 with IBS and 17 healthy subjects); 46 fecal samples, but no mucosal samples, were collected and analyzed. For each subject, we measured exhaled H 2 and CH 4 , oro-anal transit time, and the severity of psychological and gastrointestinal symptoms. Fecal methanogens were measured by quantitative polymerase chain reaction. Numerical ecology analyses and a machine learning procedure were used to analyze the data. Fecal microbiota showed covariation with mucosal adherent microbiota. By using classic approaches, we found no differences in fecal microbiota abundance or composition between patients with IBS vs healthy patients. A machine learning procedure, a computational statistical technique, allowed us to reduce the 16S ribosomal RNA data complexity into a microbial signature for severe IBS, consisting of 90 bacterial operational taxonomic units. We confirmed the robustness of the intestinal microbial signature for severe IBS in the validation set. The signature was able to discriminate between patients with severe symptoms, patients with mild/moderate symptoms, and healthy subjects. By using this intestinal microbiota signature, we found IBS symptom severity to be associated negatively with microbial richness, exhaled CH 4 , presence

These practice parameters are an update of the previously published recommendations regarding the use of autotitrating positive airway pressure (APAP) devices for titrating pressures and treating adult patients with obstructive sleep apnea syndrome. Continuous positive airway pressure (CPAP) at an effective setting verified by attended polysomnography is a standard treatment for obstructive sleep apnea (OSA). APAP devices change the treatment pressure based on feedback from various patient measures such as airflow, pressure fluctuations, or measures of airway resistance. These devices may aid in the pressure titration process, address possible changes in pressure requirements throughout a given night and from night to night, aid in treatment of OSA when attended CPAP titration has not or cannot be accomplished, or improve patient comfort. A task force of the Standards of Practice Committee of the American Academy of Sleep Medicine has reviewed the literature published since the 2002 practice parameter on the use of APAP. Current recommendations follow: (1) APAP devices are not recommended to diagnose OSA; (2) patients with congestive heart failure, patients with significant lung disease such as chronic obstructive pulmonary disease; patients expected to have nocturnal arterial oxyhemoglobin desaturation due to conditions other than OSA (e.g., obesity hypoventilation syndrome); patients who do not snore (either naturally or as a result of palate surgery); and patients who have central sleep apnea syndromes are not currently candidates for APAP titration or treatment; (3) APAP devices are not currently recommended for split-night titration; (4) certain APAP devices may be used during attended titration with polysomnography to identify a single pressure for use with standard CPAP for treatment of moderate to severe OSA; (5) certain APAP devices may be initiated and used in the self-adjusting mode for unattended treatment of patients with moderate to severe OSA without

[Purpose] The aim of this study was to ascertain the prevalence of chronic widespread musculoskeletal pain in patients with obstructive sleep apnea syndrome and to assess the relationship between sleep disorder and pain, quality of life, and disability. [Subjects and Methods] Seventy-four patients were included in the study and classified as having mild, moderate, or severe obstructive sleep apnea. Chronic widespread pain, quality of life, and disability were evaluated. [Results] Forty-one patients (55.4%) had chronic widespread pain. Female patients had a higher incidence of chronic pain, and female patients with chronic pain had higher body mass indexes, pain levels, and disability scores than did male patients. Physical component scores of female patients with chronic pain were lower than those of male patients. No correlation was observed between the degree of sleep disorder and severity of pain, pain duration, disability, or quality of life in obstructive sleep apnea patients with pain. [Conclusion] This study showed a 55.4% prevalence of chronic widespread pain in patients with obstructive sleep apnea and a greater risk of chronic pain in female than in male patients. Female patients with obstructive sleep apnea and chronic pain have higher pain and disability levels and a lower quality of life.
