To analyze the outcomes of j-pouch and side-to-end anastomosis in rectal cancer patients treated with laparoscopic hand-assisted low anterior resection. Prospective trial on cases randomized to have a colonic j-pouch or a side-to-end anastomosis after low anterior resection. Demographics, characteristics of disease and treatment, perioperative results, and functional outcomes and life quality were compared between the groups. Seventy four patients were randomized. Reservoir creation was withdrawn in 17 (23%) patients, mostly related to reach problem (n = 11, 64.7%). Anastomotic leakage rate was significantly higher in j-pouch group (8 [27.6%] vs. 0, p = 0.004). Stoma closure could not be achieved in 16 (28.1%) patients. Life quality and functional outcomes, measured 4, 8 and 12 months after the stoma reversal, were similar. Colonic j-pouch and side-to-end anastomosis are similar regarding perioperative measures including operation time, rates of postoperative complications, reoperation and 30-day mortality, and hospitalization period except anastomotic leak rate, which is higher in j-pouch group. Postoperative aspects are not different in patients receiving either technique including functional outcomes and life quality for the first year after stoma closure. In our opinion, both techniques may be preferred during the daily practice while performing laparoscopic surgery; but surgeons may be aware of a possibly higher anastomotic leak rate in case of a j-pouch.

Antimicrobial Protection of Marsupial Pouch Young

PubMed Central

Cheng, Yuanyuan; Belov, Katherine

2017-01-01

Marsupials diverged from eutherian mammals about 148 million years ago and represent a unique lineage of mammals with distinctive morphological and reproductive characteristics. Marsupials have significantly shorter gestation periods than eutherians. Pregnancy typically ranges from 15 to 35 days, with young being born at a very early developmental stage and lacking differentiated lymphoid tissues and mature effector cells. Recent microbiome studies of the marsupial pouch revealed that marsupial young can face intense microbial challenges after birth, as the pouch contains a broad range of Gram-positive and Gram-negative bacteria. Antimicrobials are believed to play a significant role in the immune protection of marsupial newborns during their pouch life. The skin of the post-reproductive pouch secretes antimicrobial lysozyme and dermcidin, which may contribute to the decreased density of certain bacteria in the pouch. A range of antimicrobial agents, such as immunoglobulins, lysozyme, transferrin, and cathelicidins, have been identified in marsupial milk. Antimicrobial assays have revealed that marsupial cathelicidins have broad-spectrum activity against a variety of bacteria and fungi, including several multi-drug resistant strains. In this article, we will review the action mechanisms of these antimicrobial compounds and discuss how they protect marsupial newborns from potentially pathogenic bacteria inside the pouch. We will also discuss the potential of marsupial antimicrobial compounds as a source of novel antibiotics. PMID:28326070

[A case of strangulated congenital diaphragmatic hernia with necrosis and rupture of the colon and herniation into a left hemithorax in an adult (author's transl)].

Sarris, M; Georgoulis, J; Gatos, M; Dariotis, A

This is a case report of a successful repair of congenital diaphragmatic hernia in a 48 years old male that contained the transverse colon which was strangulated and ruptured in the left thoracic cavity. It was approached in two stages. First through a laparotomy the proximal part of the transverse colon was divided. The side going to the hernial sac was sutured and the proximal stump was anastomosed to the descending colon. In a second stage, two days later, through a felt thoracotomy the strangulated and ruptured colon was resected and the distal stump of the transverse colon was sutured and the hernia repaired.

The etiology of pouch inflammation after restorative proctocolectomy is unknown. The fecal stream and immunological reactions are potential pathological factors. This study was performed to examine the impact of the fecal stream and stasis on immunological reactions in the pouch. Patients who underwent a restorative proctocolectomy with a covering ileostomy for ulcerative colitis were studied. Mucosal biopsy specimens were obtained from both the pouch and the proximal ileum at the time of ileostomy closure, and 3, 6, and 12 months after ileostomy closure. As a control group, normal ileal biopsies were obtained from patients with colonic polyps. At the time of ileostomy closure, mucosal interleukin-1beta, interleukin-6, interleukin-8, and tumor necrosis factor-alpha levels in the pouch and the proximal ileum were not significantly different from those in the normal control group. At 3 months after ileostomy closure, the mucosal cytokine levels in the pouch increased significantly compared with those at ileostomy closure, and their levels were significantly higher than those in the proximal ileum. At 6 and 12 months after ileostomy closure, the mucosal cytokine levels in the pouch did not change significantly compared with those at 3 months after ileostomy closure. The mucosal cytokine levels in the proximal ileum did not change significantly during the entire study. The immunological reactions in the pouch occurred soon after ileostomy closure, and continued for at least 1 yr. The fecal stream and stasis play an important part in the pathogenesis of immunological reactions in the ileal pouch.

Morbid obesity defined as BMI > 40 is a growing problem. It is primarily treated with diet, lifestyle changes, and medicine. However, at present, surgery remains the only effective option for the management. Seventeen patients were studied 2 months after laparoscopic gastric banding. The aims were to evaluate the association between (1) the extent of pouch filling and satiety, (2) gastric emptying and weight loss, and (3) the pouch pressure during a meal and the sensation of satiety and weight loss. The preoperative weight was 146 kg (range 108-202 kg). The average weight loss was 21 kg between the banding and the examination. The half time (T (50%)) for the pouch emptying was 3 min (quartiles 3-12.5) and the time to 90% of pouch emptying (T (90%)) was 40 min (24.5-60). The sensation of satiety lasted 75 min (57.5-105), and the feeling of hunger started after 90 min (40-90). Neither T (50%) nor T (90%) correlated to the weight loss (R = 0.006, P > 0.5 and R = 0.1, P > 0.5). The sensation of satiety did not correlate to T (50%) or T (90%) (R = 0.6, P = 0.12 and R = 0.5, P = 0.15). No association was found between the sensory data and the pressure decline. Significant association was found between the load of the meal expressed as the area under the pouch pressure curve and the weight loss (R = 0.786, P = 0.015). The satiety sensation lasted much longer than the pouch emptying and the pressure increase. The pressure load correlated to the weight loss. This indicates that neuroendocrine mechanisms caused by the accumulated mechanical load are most important for maintaining satiety.

Characterization of Commercial Li-ion Cells in Pouch Format

2014-01-01

The li-ion pouch design cells exhibit similar behavior under off-nominal conditions as those in metal cans that do not have the internal safety devices. Safety should be well characterized before batteries are designed. Some of the li-ion pouch cell designs studied in this program reacted most violently to overcharge conditions at the medium rates but were tolerant to overcharge at very low rates. Some pouch cell designs have higher tolerance to vacuum exposures than some others. A comparison of the pouch material itself does not show a correlation between this tolerance and the number of layers or composition of the pouch indicating that this is a property of the electrode stack design inside the pouch. Reduced pressure (8 to 10 psi) test environments show that the extent of capacity degradation under reduced pressure environments is much less than that observed under vacuum conditions. Lithium-ion Pouch format cells are not necessarily true polymer cells.

To assess the frequency of anterior pharyngeal pouch formation after total laryngectomy, and to discuss the causes and consequences of anterior pharyngeal pouch formation. A prospective, observational study of 43 patients undergoing total laryngectomy. Data collected included laryngeal defect closure type, tumour staging and demographic information. A barium swallow was performed on day 7-14 after surgery to assess for anterior pharyngeal pouch formation and fistula formation. The incidence of anterior pharyngeal pouch formation was 47 per cent. Patients who did not have an anterior pharyngeal pouch on swallow imaging assessment were less likely to develop a pharyngo-cutaneous fistula. There was no statistically significant association between laryngeal defect closure type and anterior pharyngeal pouch formation. The anterior pharyngeal pouch is a dynamic phenomenon best investigated with a fluoroscopic swallow imaging study. Its causes are multi-factorial. Absence of an anterior pharyngeal pouch appears to confer protection against pharyngo-cutaneous fistula formation, hastening commencement of adjuvant therapy and an oral diet.

We evaluated the surgical feasibility, sexual satisfaction and complications of vaginal reconstruction with sigmoid colon in patients with congenital absence of vagina and menses retention. Retrospective analysis of surgical techniques and long-term postoperative follow-up was performed for 22 patients who underwent vaginal reconstruction with sigmoid colon at a single hospital between 1977 and 2011 to treat congenital absence of vagina with menses retention. All patients achieved satisfactory sexual function after marriage. No patients experienced enterospastic abdominal pain during sexual intercourse. The neovaginas accommodated two or more fingers and had depths >10 cm. The mucous membranes were soft and flexible, and secretions of the sigmoid mucosa provided adequate and acceptable lubrication. No patient required vaginal stents, and none developed vaginal stenosis or reported pain with vaginal expansion. Fifteen of the 22 patients underwent hysterectomies due to cervical agenesis; seven retained their uterus and had onset of normal menses postoperatively. Two patients became pregnant 1 year after marriage; one achieved 38-week gestation, underwent cesarean section due to premature rupture of membranes, and delivered a healthy boy. The other experienced natural incomplete abortion and underwent curettage at her local hospital. This study confirms that sigmoid colon vaginal reconstruction is a good choice for treating congenital absence of vagina and menses retention and results in the closest approximation to the physical function of a normal female vagina. Reproductive ability can be retained in many cases for patients with a well-developed uterus and cervix.

An accessory penis is a very rare anomaly. Only five cases have been reported thus far to our knowledge. We present the case of a child aged 2 years and 10 months who had a penis-like structure (containing phallus and glans) attached to the right buttock. Associated anomalies were a non-communicating type of colonic duplication, a paramedian stenosed anal opening, a horse-shoe kidney, posterior urethral valves, scoliosis of the lumbo-sacral spine, polydactyly and equino-varus deformity of the right foot. As far as we can tell, this is the first report of an accessory penis associated with colonic duplication and other congenital anomalies. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Psychological impact of colostomy pouch change and disposal.

McKenzie, Frances; White, Craig A; Kendall, Sally; Finlayson, Aileen; Urquhart, Mary; Williams, Isabel

This article presents some of the findings from a multicentre cross-sectional correlational study to evaluate the relationship between colostomy pouch change and disposal practices and the patient's psychological wellbeing. Five questionnaires were used in a one-off interview with 86 patients. Patients were assessed at between one and four months postoperatively. Results from the Pouch Change and Disposal questionnaire showed that only 25% of patients found disposal of used appliances the most difficult part of their pouch change and disposal routine. Half felt that their body was out of their control and 33% reported avoiding social and leisure activities due to what was involved in their pouch change and disposal routine. Patients cited several factors, such as minimizing odour and having an appliance that could flush away, as factors which would help them to stop avoiding these activities. Stoma care nurses have a unique opportunity to improve the psychological wellbeing of their patients by considering the aspects of pouch change and disposal that pose the greatest challenge to individuals. Use of a modified version of the Pouch Change and Disposal questionnaire may be a useful tool in identifying those at risk of impaired quality of life.

A case of long diverticular colonic duplication producing acute abdominal pain in a 6-year-old girl is presented. Physical examination showed no signs of acute abdomen at the initial presentation. After a pain-free interval, there was a sudden onset of severe abdominal pain and a large tumor in the lower abdomen was observed. A plain x-ray showed an enormously dilated colonic pouch filled with gas. Excision of the T-shaped duplication and small part of the transverse colon was successful. Because of extensive fibrotic changes in the colon near the opening of duplication, a resection margin of at least 2 cm is recommended.

Safety and Long-Term Performance of Lithium-ion Pouch Cells

NASA Technical Reports Server (NTRS)

Jeevarajan, Judith

2012-01-01

Lithium-ion batteries have the highest energy density of the batteries available in the commercial market today. Although most lithium-ion cell designs use a metal can design, this has changed significantly in recent years. Cell designs are offered in the pouch format as they offer better volumetric and gravimetric energy densities and in some cases, higher tolerance to abuse or off-nominal conditions. In the past decade, several state-of-the-art lithium-ion pouch cell designs have been tested. The pouch cell designs have become more robust in the past two years but there are still a few issues that need to be looked into for optimization. The pouch cells seem to have a tendency to swell when left in storage under ambient conditions. The cells also swell under overvoltage and undervoltage conditions. A significant issue that has been observed is the swelling of the cells under a vacuum condition which could lead to deformation of the cell pouch after this exposure. This last factor would be very critical in the use of these cell designs for space applications as vacuum exposure is used to check for cell and battery leaks before it is flown into space. In rare cases, corrosion of the aluminum layer of the pouches has been observed in stored cells. Pouch material analysis has been carried out in an effort to understand the strength of the pouches and determine if this is a factor in the corrosion as well as unsafe condition of the cells as deformation of the inner layers of the pouch could occur when the cells swell under the various conditions described above. Pouch materials are typically aluminized plastic, made up of a layer of Al sandwiched between one or more layers of polymeric material. Deformations or cell manufacturing processes could lead to a compromise of the inner polymeric layer/s of the pouch leading to the corrosion of the Al layer in the aluminized pouch material. The safety of the pouch cell designs has been determined for cells from various

Methicillin-resistant Staphylococcus aureus (MRSA) is recognized as a cause of nosocomial infections in both human and veterinary medicine. Studies that examine the nasopharynx and guttural pouches of the horse as carriage sites for MRSA have not been reported. MRSA colonizes the nasopharynx and guttural pouch of horses. To determine the prevalence of MRSA in equine nasopharyngeal wash (NPW) and guttural pouch lavage (GPL) samples in a field population of horses. One hundred seventy-eight samples (123 NPW and 55 GPL) from 108 horses. Prospective study. Samples were collected from a convenience population of clinically ill horses with suspected Streptococcus equi subsp. equi (S. equi) infection, horses convalescing from a known S. equi infection, and asymptomatic horses undergoing S. equi screening. Samples were submitted for S. aureus aerobic bacterial culture with mannitol salt broth and two selective agars (cefoxitin CHROMagar as the PBP2a inducer and mannitol salt agar with oxacillin). Biochemical identification of Staphylococcus species and pulsed-field gel electrophoresis (PFGE), to determine clonal relationships between isolates, were performed. Methicillin-resistant Staphylococcus (MRS) was isolated from the nasopharynx of 7/108 (4%) horses. Three horses had MRSA (2.7%), and 4 had MR-Staphylococcus pseudintermedius (MRSP). MRSA was isolated from horses on the same farm. PFGE revealed the 3 MRSA as USA 500 strains. Sampling the nasopharynx and guttural pouch of community-based horses revealed a similarly low prevalence rate of MRSA as other studies sampling the nares of community-based horses. More study is required to determine the need for sampling multiple anatomic sites when screening horses for MRSA. Copyright © 2017 The Authors.

The infrequent mention of epipharyngeal pouches occurring in some species of bears indicates the scarcity of morphological and functional knowledge about these structures. In order to provide precise morphological data on the structure of these remarkable formations and to verify their taxonomic utility, the pharyngeal regions of 1 spectacled bear and 3 brown bears were examined. All these individuals possessed epipharyngeal pouches, which are tubular, blind-ending outpouchings of the caudodorsal pharyngeal wall equipped with respiratory epithelium and a thick layer of elastic fibres. While the spectacled bear and Ursus arctos syriacus possessed a single pouch on the caudodorsal wall of the nasopharynx, in Ursus arctos and Ursus arctos beringianus 2 unequally sized pouches were present. Two additional sacs of smaller size, representing outpouchings of the lateral pharyngeal wall, occurred in the spectacled bear. These findings prove epipharyngeal pouches to be constant and unique morphological features of the family Ursidae, the anatomical features suggesting involvement in the respiratory system most probably in important aspects of ursid phonation. This is the first description of epipharyngeal pouches in the spectacled bear. PMID:11322723

In this paper, we describe operative technique details and our results with a modified technique for jejunal pouch formation and interposition after total gastrectomy, with an overall aim to achieve results superior to jejunal pouch and Roux-en-Y reconstruction, as reported in the literature. Following total gastrectomy, the jejunum was divided approximately 20 cm distal to the ligament of Treitz. Marginal vessels were not divided in order to preserve the nerves in the 50 cm of distal jejunum which would be used for pouch construction. The pouch was constructed using a linear stapler (Endo GiA, United States Surgical Corp., Norwalk, Conn). A total of 15 gastric cancer patients underwent construction of a nerve-preserving jejunal pouch and interposition following total gastrectomy. None of the patients experienced postoperative complications due to pouch construction. Additionally, discomforts such as dumping or stagnation were not observed. Mild reflux esophagitis occurred in five of the 15 patients and was resolved by oral administration of camostat mesilate. Six months after surgery, the average patient's diet volume and body weight had gradually increased to 79% and 86%, respectively, of the presurgical levels. A dual phase, dual isotope radionucleid pouch emptying study was also performed six months after surgery. The intra-pouch RI retention rate was 47% for liquid food and 53% for solid food 120 minutes after intake. The emptying rate was slower for both solid and liquid food, as compared with healthy individuals. The pouch-emptying test demonstrated a satisfactory retention capacity and an acceptable emptying time as a gastric substitute. The patients who underwent gastric reconstruction with a nerve-preserving jejunal pouch with interposition have experienced a reasonably good quality of life.

Pouch dilatation following laparoscopic adjustable gastric banding: psychobehavioral factors (can psychiatrists predict pouch dilatation?).

2004-01-01

Laparoscopic adjustable gastric banding is increasingly being performed in morbidly obese individuals for weight loss. Some patients develop pouch dilatation as a postoperative complication that limits the utility of the procedure. Surgical variables are poor predictors of this complication. 5 patients from a series of 157 who underwent LAGB at a single center developed the condition. Psychiatric and surgical case-notes were analyzed retrospectively for the presence of operationally defined psychiatric disorders and compared to 10 controls from the same population. Cases were significantly more likely to have past or current binge eating, emotionally triggered eating with reduced awareness of the link, a history of affective disorder, reduced sexual functioning and successful preoperative weight loss. No difference between groups was observed for compliance with orlistat, childhood sexual abuse, relationships with parents, history of bulimia nervosa, rate of band inflation or preoperative BMI. Psychological factors may be better predictors of pouch dilatation than biomedical variables. Disordered eating can be an attempt to modulate negative emotions. Pouch dilatation may be a consequence of this eating behavior.

To identify the most common pathogens involved in infections of third and fourth branchial pouch cysts. Third and fourth branchial pouch cyst infections are an uncommon cause of anterior neck abscesses often confused with other entities, such as thyroglossal duct cysts and thyroid abscesses leading to misdiagnosis, recurrence, and increased morbidity related to a delay in diagnosis and appropriate treatment. Retrospective chart and literature review. Retrospective chart review case series of patients presenting to the Bobby R. Alford Department of Otolaryngology at Texas Children's Hospital from July 2004 to July 2008 with third and fourth branchial pouch cysts. A total of 11 patients were identified. All patients had left-sided lesions. Eikenella corrodens was found in 60% of cultures and was the most common organism identified in our patient group. Furthermore, 56% of the organisms isolated were anaerobic. All organisms with the exception of Staphylococcus aureus were identified as oral cavity flora. Third and fourth branchial pouch cysts provide a communication between the neck and the oral cavity through pyriform sinus tracts. The presence of oral cavity flora in a left anterior neck abscess should raise the suspicion of a branchial pouch anomaly, and subsequently alter therapeutic management.

The aim of this project was to establish and maintain an internet-based database of all ileal pouch procedures performed in major centres in Australasia. The initial three colorectal units contributing data are Auckland, northern Brisbane and Central Sydney Area Health Service. A web-based database was designed. The data collection method was tested on a subgroup of 20 patients to ensure functionality. Data were collected in five main categories: patient demographics, preoperative data, operative details, postoperative complications and functional results. Initial data are presented for 516 patients [363 J, (70%), 133 W (26%), 16 S pouches (3%)]. There were two deaths within 30 days (0.4%). The anastomotic leak rate overall, in handsewn (HSA) and stapled anastomoses (SA) respectively was 5.0%, 8.5% and 3.3% (P=0.02 for difference HSA vs SA). Incidence of pouchitis was 20% (ulcerative colitis 23%, Crohn's disease 20%, indeterminate colitis 22%, familial adenomatous polyposis 9%). Incidence of anal stricture requiring intervention (11% overall) was significantly greater in HSAs than in SAs (16%vs 9%, P=0.02). Incidence of small bowel obstruction at any time postoperatively was 16%. Functional data were available for 234 patients. The median frequency of bowel actions during waking hours was significantly less in W pouches than in J pouches (four vs five, P=0.0005). A national web-based database has been developed for access by all Australasian colorectal units. Initial Australasian data compare favourably with other international studies. Pouchitis continues to be a long-term problem. The leak rate and rate of late anal stricture requiring a procedure are higher if the anastomosis is handsewn rather than stapled. Functional results are better with the W pouch than with the J pouch.

Lateral congenital anomalies of the pharyngeal apparatus: part III. cadaveric representation of the course of second and third cleft and pouch fistulas.

"Stepladder" surgery for fistula from second or third pharyngeal cleft and pouch is "blind." Neither intraoperative methylene blue injection and probing nor preoperative imaging (fistulogram ultrasound, computed tomography, magnetic resonance imaging) reveal three-dimensional anatomic relations of fistulas. This article describes the most common second and third fistula courses and demonstrates representation of their tracts with wires in human cadavers. A second cleft and pouch fistula, at its external opening, pierces superficial cervical fascia (and platysma), then investing cervical fascia, and travels under the sternocleidomastoid muscle, superficial to the sternohyoid and anterior belly of omohyoid. It ascends along the carotid sheath, and at the upper border of the thyroid cartilage it pierces the pretracheal fascia. Characteristically, it courses between the carotid bifurcation and over the hypoglossal nerve. After passing beneath the posterior belly of the digastric muscle and the stylohyoid, it hooks around both glossopharyngeal nerve and stylopharyngeus muscle. The fistula reaches the pharynx below the superior constrictor muscle. The course of a third cleft and pouch fistula is similar until it has pierced pretracheal fascia; then it passes over the hypoglossal nerve and behind the internal carotid, finally descending parallel to the superior laryngeal nerve, reaching the thyrohyoid membrane cranial to the nerve.

According to up-to-date concepts for local spread of a rectal cancer it is possible to perform a radical rectal resection with a restorative anastomosis inspite of the fact that the tumor is located in the middle or the distal third of the rectum. Usually a total resection of the rectum and coloanal anstomosis have to be performed. There are two ways to restore the continuity of the gut: a straight coloanal anstomosis or J pouch anastomosis. 22 patients with rectal cancer localized between 4 and 9 cm from the anal verge, were operated and restorative anastomoses were performed. The first 18 patients were with a straight coloanal anastomosis. In the last 4 cases coloanal anastomoses were done between the anus and colocolic 7 cm J pouch. During the first month there were 6 patients with total and 9 with partial incontinence in the group with straight coloanal anastomosis. Transrectal sonography confirmed contractility of the puborectal muscle and sphinctermanometry showed lower resting tone and squeeze pressure in cases with incotinence. No incontinence was observed in the group with J pouch and the shinctermanometry data were the same as these of healthy controls. The rectal ampula has reservoir function and its loss after total resection of the rectum is the reason for frequent bowel movements, urgency and leakage. Reconstruction with a colonic J pouch is associated with better bowel function compared to the straight coloanal anastomosis.

Morphology of brood pouch formation in the pot-bellied seahorse Hippocampus abdominalis.

The reproductive strategies of vertebrates are diverse. Seahorses (Pisces: Syngnathidae) possess the unique characteristic of male pregnancy; i.e., males, not females, incubate embryos in a specialized structure called a 'brood pouch'. The brood pouch is formed along the ventral midline of the tail. The lumen of the brood pouch is surrounded by loose connective tissue, called pseudoplacenta, and dermis. We visualized and evaluated the morphology of brood pouch formation in Hippocampus abdominalis to gain generalizable insights into this process in seahorses. First, we employed several staining methods to characterize the pseudoplacenta and dermis of the brood pouch of mature male seahorses. The pseudoplacenta is composed mainly of reticular fibers, while the dermis is composed mainly of collagenous fibers. Further observations showed that pouch formation is initiated by linear projections of epithelia on both ventrolateral sides of the body. These projections elongated toward the ventral midline, eventually fused together, and then formed a baggy structure composed of a single dermis layer with neither smooth muscle nor pseudoplacenta. Finally, the pseudoplacenta was formed, together with two layers of dermis and smooth muscle. Thus, a fully developed brood pouch was established. The morphology of the luminal epithelium also changed during pouch formation. We analyzed the localization of C-type lectins as markers; haCTL II was localized in both the outer and luminal epithelia of the brood pouch throughout development in the male seahorse, whereas haCTL IV, which was not detected in the early stage of seahorse development, became localized only in the luminal epithelium as development proceeded. We categorized the processes of brood pouch formation during male seahorse development into three stages: (1) the early stage, characterized by formation of a baggy structure from the primordium; (2) the middle stage, characterized by the differentiation and establishment of

SUMMARY The pharyngeal pouches, which form by budding of the foregut endoderm, are essential for segmentation of the vertebrate face. To date, the cellular mechanism and segmental nature of such budding have remained elusive. Here, we find that Wnt11r and Wnt4a from the head mesoderm and ectoderm, respectively, play distinct roles in the segmental formation of pouches in zebrafish. Time-lapse microscopy, combined with mutant and tissue-specific transgenic experiments, reveal requirements of Wnt signaling in two phases of endodermal epithelial transitions. Initially, Wnt11r and Rac1 destabilize the endodermal epithelium to promote the lateral movement of pouch-forming cells. Next, Wnt4a and Cdc42 signaling induce the rearrangement of maturing pouch cells into bilayers through junctional localization of the Alcama immunoglobulin-domain protein, which functions to restabilize adherens junctions. We propose that this dynamic control of epithelial morphology by Wnt signaling may be a common theme for the budding of organ anlagen from the endoderm. PMID:23375584

A simplified technique for continent urinary diversion: an all-stapled colonic reservoir.

PubMed

Parra, R O

1991-12-01

A simple continent colonic reservoir was constructed in its entirety with the aid of surgical stapling techniques in 17 men and 10 women. In 5 men an orthotopic pouch was created and in the rest a continent stoma was designed. Detubularization of the entire colonic segment assures a low pressure system with disruption of directional peristaltic activity. The ureters are implanted by simply burying them in a mucosal furrow. Operative time required for the creation of the reservoir (excluding time for cystectomy) has ranged between 70 and 140 minutes (mean 95.4 minutes). With a followup of 9 to 60 months (mean 22.8 months) continence has been achieved in all but 1 patient with no ureteral reflux or obstruction. Urodynamically the pouch has achieved a large capacity (mean 750 cc) with low filling pressures (8.1 cm. water) because of technical ease of construction together with a shortened operative time due to the stapling techniques. This form of bladder replacement offers an option for select patients in whom continent urinary diversion is contemplated.

Ulcerative colitis (CU) or Familiar Polyposis (FAP) can be the indication for proctocolectomy reconstructed with J pouch. The complete removal of the colon mucosa is essential regarding the late complications and at the same time the atraumatic surgical technique is very important concerning on the long term functional results. Both aspects seems to be answered by the stapled ileo-anal anastomosis using a "procedure for prolaps and haemorrhoids (PPH)" stapler applied by us since 2000. 117 proctocolectomies reconstructed with J pouch and ileo-anal anastomosis were performed in our department between March 1990 and September 2016 indicated by CU or by FAP. In the first time period the ileo-anal anastomosis was sutured by hand (29 cases) and since 2000 the PPH stapler was applied as a routine (88 patients). Deviating ileostomy was performed in most cases of us. The data of the 117 patients were collected from the database of our hospital, 45 of them were interviewed personally and another 31 patients were contacted by phone, so 76 patients (65%) were eligible for follow-up. Frequency of stool, use of loperamid, level of incontinence (Wexner score) and perianal dermatitis were detected. The mean follow-up time was 18.6 years in the hand-sewn anastomosis group and 7.6 years in the PPH group. In the hand-sewn anastomosis group in 4/29 cases (13.8%) the removal of the pouch with definite ileostomy were necessary (2 pouchitis, 1 pouch necrosis, 1 recidiv rectum cancer); the mean stool frequency was 4.3 per day; the Wexner incontinence score was 8.5 and 2/15 patients (13.3%) live with ileostomy caused by incontinence. In the PPH stapled ileo-anal anastomosis group in 4/88 cases (4.5%) were the pouch removed (caused by pouchitis), the mean stool frequency was 4.0 per day; the Wexner score was 7.6 and 4/61 patients (6.6%) live with ileostomy caused by incontinence. Based on our experience the ileo-anal anastomosis performed by PPH stapler is technically feasible, seems to be

Colon replacement of vagina to restore menstrual function in 11 adolescent girls with vaginal or cervicovaginal agenesis.

Cervicovaginal or vaginal agenesis with functioning endometrial tissue is rare. We report the construction of a colon conduit which is anastomosed to posterior uterine wall or upper vaginal pouch to allow menstruation. We report seven girls with cervicovaginal agenesis and four with lower vaginal agenesis (aged 12-20 years) who presented with painful cryptomenorrheoa. All the girls wanted to conserve their uterus and menstruate normally. A colon conduit was constructed for the egress of menstrual blood. The colon conduit was anastomosed to the posterior uterine wall in the seven girls with cervicovaginal agenesis and to the distended upper vaginal pouch in the four girls with vaginal agenesis. Utero-colonic neovaginal anastomosis was performed only after excising a circular portion of the posterior myometrium to prevent stenosis. The colon conduit functioned effectively, providing an egress for regular painless menstruation. One patient had stenosis of the perineal neovaginal orifice for which dilations were done. One girl has married and reports satisfactory intercourse. The mean follow up is 2.2 years. This group of patients forms a separate subgroup needing a conduit not only for sexual function but also for menstruation. However, if treated by the method described herein, they should be cautioned against pregnancy if they have cervicovaginal agenesis and against vaginal delivery if they have vaginal agenesis.

Dietary and behavioral modifications have resulted in limited long-term success in curing morbidly obese patients, and surgery remains the only effective treatment. Of the surgical procedures that are the most commonly offered, Roux-en-Y gastric bypass (RYGB) appears to offer the best long-term results. However 5-15% of patients will not achieve successful weight loss after RYGB. There are many reports showing that the patients who underwent gastric bypass surgeries regain weight over time. The cause for this remains unclear. Several factors may contribute, including dilation of the gastric pouch and the gastrojejunal anastomosis. However, the data to support the link is sparse. The objective of this paper is to describe the surgical technique of wrapping the gastric pouch with a polytetrafluoroethylene (PTFE) mesh to prevent gastric pouch dilatation. In specific, we created a 20-30 ml gastric pouch and subsequently, the gastrojejunostomy was performed with a circular stapler. Afterwards, the mesentery was dissected and the gastric pouch was wrapped with the PTFE mesh. We have performed this procedure on three cadavers with an average operative time of 75 minutes. We found that the procedure of wrapping the gastric pouch was not particularly difficult. As a result, the gastric pouch, gastrojejunal anastomosis and the stump of the jejunum are all totally wrapped within the mesh. It may be effective in the prevention of dilatation.

To evaluate the disease course and management strategy for pouch neoplasia. Patients undergoing ileal pouch surgery for underlying ulcerative colitis who developed low-grade dysplasia (LGD), high-grade dysplasia, or adenocarcinoma in the pouch were identified. All eligible 44 patients were evaluated. Of the 22 patients with initial diagnosis of pouch LGD, 6 (27.3%) had persistence or progression after a median follow-up of 9.5 (4.1-17.6) years. Family history of colorectal cancer was shown to be a risk factor associated with persistence or progression of LGD (P = 0.03). Of the 12 patients with pouch high-grade dysplasia, 5 (41.7%) had a history of (n = 2, 16.7%) or synchronous (n = 4, 33.3%) pouch LGD. Pouch high-grade dysplasia either persisted or progressed in 3 patients (25.0%) after the initial management, during a median time interval of 5.4 (2.2-9.2) years. Of the 14 patients with pouch adenocarcinoma, 12 (85.7%) had a history of (n = 2, 14.3%) or synchronous dysplasia (n = 12, 85.7%). After a median follow-up of 2.1 (0.6-5.2) years, 6 patients with pouch cancer (42.9%) died. Comparison of patients with a final diagnosis of pouch adenocarcinoma (14, 32.6%), and those with dysplasia (29, 67.4%) showed that patients with adenocarcinoma were older (P = 0.04) and had a longer duration from IBD diagnosis or pouch construction to the detection of pouch neoplasia (P = 0.007 and P = 0.0013). The risk for progression of pouch dysplasia can be stratified. The presence of family history of colorectal cancer seemed to increase the risk for persistence or progression for patients with pouch LGD. The prognosis for pouch adenocarcinoma was poor.

The purpose of this study was to compare experiences and concerns about pouch seal leakage between persons with ostomies residing in North America (Canada and the United States) and Europe (United Kingdom, Netherlands, Sweden, Germany, Belgium, France, and Italy). Differences in reported pouch wear time and accessories used between the 2 groups were also examined. Secondary analysis of data from a cross-sectional study (Ostomy Life Study). Responses from persons residing in European countries (n = 1939) were compared with responses of 1387 individuals residing in North American countries. Persons with an ostomy completed a questionnaire that focused on 4 topics related to the daily use of an ostomy pouching system (pouch seal leakage, ballooning, appearance of pouching system such as color and size of the pouch and whether it is discrete under clothing, and coupling failure of 2-piece pouching systems). Pouch seal leakage was defined as stomal effluent seeping between the skin and the wafer of the ostomy pouching system. Statistical analysis was performed using a proportional odds model including various variable effects. Special attention was given to frequency of pouch seal leakage occurrences. All tests were 2-sided; P values ≤.05 were deemed statistically significant. Participants living in the North American countries indicated they were more likely to experience leakage from the ostomy (odds ratio = 2.610, 95% CI 2.187-3.115; P < .0001). Findings also indicated they were more likely to worry about pouch seal leakage than those in the European countries' data set (odds ratio = 2.722, 95% CI 2.283-3.246; P < .0001). Participants residing in the North American countries had significantly longer wear times than those participants in the European countries (P < .0001, χ test). The use of accessories was associated with a longer pouching system wear time. Study results suggest that participants from the North American countries indicated significantly more

To assess the application of multiple planar volume reconstruction (MPVR) and three-dimensional (3D) transparency lung volume rendering (TL-VR) with 64-row multidetector-row computed tomography (MDCT) in neonates with congenital esophageal atresia (EA) and distal tracheoesophageal fistula (TEF). Twenty neonates (17 boys, 3 girls) with EA and distal TEF at a mean age of 4.6 d (range 1-16 d) were enrolled in this study. A helical scan of 64-row MDCT was performed at the 64 mm × 0.625 mm collimation. EA and TEF were reconstructed with MPVR and TL-VR, respectively. Initial diagnosis of EA was made by chest radiography showing the inserted catheter in the proximal blind-ended esophageal pouch. Manifestations of MDCT images were compared with the findings at surgery. MDCT showed the proximal and distal esophageal pouches in 20 cases. No significant difference was observed in gaps between the proximal and distal esophageal pouches detected by MPVR and TL-VR. The lengths of gaps between the proximal and distal esophageal pouches detected by MPVR and TL-VR correlated well with the findings at surgery (R = 0.87, P < 0.001). The images of MPVR revealed the orifice of TEF in 13 cases, while TL-VR images showed the orifice of TEF in 4 cases. EA and distal TEF can be reconstructed using MPVR and TL-VR of 64-row MDCT, which is a noninvasive technique to demonstrate the distal esophageal pouches and inter-pouch distance in neonates with EA and distal TEF.

Restorative proctocolectomy with ileal pouch-anal anastomosis in 203 patients: the Auckland experience.

Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become an established operation for patients with ulcerative colitis and familial adenomatous polyposis (FAP). The results of a 15-year experience with IPAA are reported. Between September 1982 and June 1997, 203 patients had IPAA surgery. From a review of the charts, data were collected on the surgical procedure, the diagnosis and early and late complications. Pouch function was assessed by means of a postal questionnaire. Of the 201 patients (median age of 32 years; 89 women) with complete records, 122 had J pouches, 65 had W pouches and 14 S pouches were constructed. The pre-operative diagnosis in 88% was ulcerative colitis and in 10% it was FAP. During a median follow-up time of 6.1 years the diagnoses were changed for 8% of the patients; in 4% the diagnosis was changed to Crohn's disease. The overall mortality was 1.5% (early = 2, late = 1). The overall morbidity was 62% (early = 17%, late = 52%). The pouch was removed or was non-functional in 9%. All patients with a final diagnosis of Crohn's disease have had their pouch excised. The median stool frequency was 4.0 (range 1.3-8.7) during the day, and 0.7 (range 0-2.1) during the night. The fewer night-time stools (J = 1.0+/-0.6; W = 0.4+/-0.5 P < 0.0001) and the reduced requirement of the W-pouch patients for anti-diarrhoeals (P = 0.004) were offset by the need for two W-pouch patients to pass a catheter to empty their pouches. The type of patients who present for IPAA surgery and the outcomes observed in this series of Auckland patients are similar to those reported from major centres elsewhere.

The mucosa of the pelvic ileal reservoir undergoes adaptive changes--inflammatory, architectural, and metaplastic--on exposure to the faecal stream. Twenty three quadruple loop ileal pouches constructed for ulcerative colitis (20 patients) and familial adenomatous polyposis (FAP) (three patients) were studied. No patient fulfilled clinical, endoscopic, or histopathological criteria for pouchitis. Standard duplicate biopsy specimens were taken from the proximal limb, the anterior wall, the posterior wall, and the body of the reservoir. An established scoring system was used and showed a highly significant increase in inflammatory scores in posterior wall biopsy specimens compared with those from the anterior wall. These results suggest that the adaptive changes are the direct result of contact with static faecal contents. One patient only showed significant inflammation in the proximal limb. There was no evidence of mucosal prolapse in any anterior wall biopsy specimen. Patients with colitis showed substantially more inflammatory and architectural changes than those with FAP. Ninety six per cent of pouches showed some colonic phenotypic expression as defined by mucin histochemical and PR 3A5 immunohistochemical studies. Our results suggest, however, that there may not be complete colonic metaplasia and that the mucin changes and other phenotypic alterations may represent a non-specific response to pouch inflammation and not a prerequisite for the development of pouchitis. The focal nature of the inflammatory and architectural changes, which may be the result of direct contact with static faecal residue, are clearly shown. A single random biopsy specimen of pouch mucosa is of limited value in assessing pathological changes and screening for potential neoplastic change within the reservoir.

Restorative proctocolectomy with IPAA improves quality of life in patients with medically refractory ulcerative colitis. Although bowel obstruction is common, pouch volvulus is rare and described only in case reports. Diagnosis can be challenging, resulting in delayed care and heightened morbidity. The purpose of this study was to delineate the symptoms and successful management strategies used in patients with IPAA volvulus that result in pouch salvage. This study was a case series. The study was conducted at a tertiary referral center for ulcerative colitis in Milwaukee, Wisconsin. Patients included those with volvulus of the IPAA. Over the study period (2010-2015), 6 patients were diagnosed with IPAA volvulus. The primary outcomes were symptom manifestation, diagnostic practices, and treatment of pouch volvulus. Six patients with ulcerative colitis were identified with pouch volvulus. The majority (n = 4) underwent a laparoscopic pouch creation and had early symptom manifestation after surgery. Complications preceding volvulus included pouch ulceration (n = 5) and pouchitis (n = 4). The most common presenting symptoms of volvulus were abdominal pain (n = 4) and obstipation (n = 4). Multiple imaging modalities were used, but volvulus was most frequently identified by CT scan. Management was primarily operative (n = 5), composed of excision of the pouch (n = 3), pouch-pexy (n = 1), and detorsion with defect closure (n = 1). Both operative and nonoperative treatment with endoscopic detorsion resulted in low morbidity and improved patient symptoms. This single-institution study is limited by its retrospective design and small number of patients. IPAA volvulus is a rare and challenging cause of bowel obstruction in ulcerative colitis. Heralding signs and symptoms, such as pouch ulceration and acute obstipation, should initiate a workup for a twisting pouch. Diagnosis, which is multimodal, must occur early to avert necrosis and allow for preservation of a well

The aim was to evaluate the impact of weight gain on pouch outcomes after ileostomy closure. Consecutive inflammatory bowel disease patients with ileal pouches followed up at our subspecialty Pouch Center from 2002 to 2011 were studied. The association of excessive weight gain (defined as a 15% increase the index weight) with pouch outcomes were evaluated using univariate and multivariate analyses. A total of 846 patients met inclusion criteria, with 470 (55.6%) being men. The mean age at the diagnosis of inflammatory bowel disease and at pouch surgery was 27.2 ± 11.9 years and 37.8 ± 12.8 years, respectively. Patients with weight gain more likely had mechanical or surgical complications of the pouch (18.4% versus 12.3%, P = 0.049), Crohn's disease of the pouch (30.6% versus 18.5%, P = 0.001), Pouch Center visits (2.0 [1.0-4.0] versus 2.0 [1.0-3.0], P = 0.008), and postoperative pouch-related hospitalization (21.1% versus 10.6%, P < 0.001). After a median follow-up of 9.0 (interquartile range = 4.0-14.0) years, 68 patients (8.0%) developed pouch failure. In the multivariate analysis, excessive weight gain was an independent risk factor for pouch failure with a hazard ratio of 1.69 (95% confidence interval = 1.01-2.84, P = 0.048) after adjusting for preoperative or postoperative use of anti-tumor necrosis factor biologics, postoperative use of immunosuppressants, Crohn's disease of the pouch, mechanical or surgical complications of the pouch, and postoperative pouch-associated hospitalization. Excessive weight gain after closure of the ileostomy is associated with worse pouch outcomes in patients with inflammatory bowel disease. Appropriate weight control may help improve pouch retention.

Bmp signaling mediates endoderm pouch morphogenesis by regulating Fgf signaling in zebrafish

PubMed Central

Swartz, Mary E.; McCarthy, Neil; Norrie, Jacqueline L.; Eberhart, Johann K.

2016-01-01

The endodermal pouches are a series of reiterated structures that segment the pharyngeal arches and help pattern the vertebrate face. Multiple pathways regulate the complex process of endodermal development, including the Bone morphogenetic protein (Bmp) pathway. However, the role of Bmp signaling in pouch morphogenesis is poorly understood. Using genetic and chemical inhibitor approaches, we show that pouch morphogenesis requires Bmp signaling from 10-18 h post-fertilization, immediately following gastrulation. Blocking Bmp signaling during this window results in morphological defects to the pouches and craniofacial skeleton. Using genetic chimeras we show that Bmp signals directly to the endoderm for proper morphogenesis. Time-lapse imaging and analysis of reporter transgenics show that Bmp signaling is necessary for pouch outpocketing via the Fibroblast growth factor (Fgf) pathway. Double loss-of-function analyses demonstrate that Bmp and Fgf signaling interact synergistically in craniofacial development. Collectively, our analyses shed light on the tissue and signaling interactions that regulate development of the vertebrate face. PMID:27122171

Seahorse Brood Pouch Transcriptome Reveals Common Genes Associated with Vertebrate Pregnancy.

2015-12-01

Viviparity (live birth) has evolved more than 150 times in vertebrates, and represents an excellent model system for studying the evolution of complex traits. There are at least 23 independent origins of viviparity in fishes, with syngnathid fishes (seahorses and pipefish) unique in exhibiting male pregnancy. Male seahorses and pipefish have evolved specialized brooding pouches that provide protection, gas exchange, osmoregulation, and limited nutrient provisioning to developing embryos. Pouch structures differ widely across the Syngnathidae, offering an ideal opportunity to study the evolution of reproductive complexity. However, the physiological and genetic changes facilitating male pregnancy are largely unknown. We used transcriptome profiling to examine pouch gene expression at successive gestational stages in a syngnathid with the most complex brood pouch morphology, the seahorse Hippocampus abdominalis. Using a unique time-calibrated RNA-seq data set including brood pouch at key stages of embryonic development, we identified transcriptional changes associated with brood pouch remodeling, nutrient and waste transport, gas exchange, osmoregulation, and immunological protection of developing embryos at conception, development and parturition. Key seahorse transcripts share homology with genes of reproductive function in pregnant mammals, reptiles, and other live-bearing fish, suggesting a common toolkit of genes regulating pregnancy in divergent evolutionary lineages. © The Author 2015.

Increased Pouch Sizes and Resulting Changes in the Amounts of Nicotine and Tobacco-Specific N-Nitrosamines in Single Pouches of Camel Snus and Marlboro Snus

PubMed Central

Jensen, Joni; Biener, Lois; Bliss, Robin L.; Hecht, Stephen S.; Hatsukami, Dorothy K.

2012-01-01

Introduction: Initial analyses of the novel smokeless tobacco products Camel Snus and Marlboro Snus demonstrated that these products contain relatively low amounts of nicotine and the carcinogenic tobacco-specific nitrosamines N’-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), as compared with traditional smokeless products. It is unknown whether the modifications in packaging, flavors, and pouch sizes that occurred for both Camel Snus and Marlboro Snus since their first introduction to the market were accompanied by any changes in nicotine or nitrosamine levels. Methods: We examined the available data on nicotine and NNN and NNK levels in 60 samples of Camel Snus and 87 samples of Marlboro Snus that were analyzed in our laboratory between 2006 and 2010. Results: Due to the increase in pouch size, the amounts of total nicotine, unprotonated nicotine, and the sum of NNN and NNK present in the large Camel Snus pouches released in 2010 are 1.9-fold, 2.4-fold, and 3.3-fold higher, respectively, than in the original smaller pouches that entered the market in 2006. Total and unprotonated nicotine content in the current version of Marlboro Snus pouches are 2.1-fold and 1.9-fold higher, respectively, and the sum of NNN and NNK is 1.5-fold lower than in the original version. Conclusions: We observed an increase in nicotine content in single portions of Camel Snus and Marlboro Snus, and an increase in tobacco-specific N-nitrosamine content in single portions of Camel Snus, due to the increases in pouch size that occurred between 2006 and 2010. This finding stresses the importance of tobacco product regulation and ingredient disclosures. PMID:22259150

Ileal J-pouch vaginoplasty: reconstruction of a physiologic vagina with an ileal J-pouch.

2009-06-01

Vaginal reconstruction has been performed for more than a century. Main complications are vaginal stenosis requiring dilatation, dyspareunia, excessive mucus secretion, and poor aesthetic and functional outcome. Here we report a new operation method modified after Baldwin for intestinal vaginoplasty in a patient with pelvic exenteration after spinal cell carcinoma of the vagina. Because of balanced liquid resorption and mucus secretion with sufficient vessel length in the terminal ileum, this intestinal segment was chosen. A J-pouch of distal ileum was constructed pedicled on the ileocolic artery and accompanying nervous plexus, transferred into the lower pelvis and sutured to the vaginal stump. One year follow-up showed a highly satisfied, sexually active patient, with adequate vaginal size, optimal lubrication and no molesting fecal odor. Terminal ileum J-pouch vaginoplasty is an optimal method for vaginal reconstruction providing a sufficient vaginal lumen and lubrication and thereby restoring patients' sexual life and increasing life quality.

Laparoscopic Restorative Total Proctocolectomy With Ileal Pouch Anal Anastomosis for Familial Adenomatous Polyposis

PubMed Central

Palanivelu, C.; Sendhilkumar, K.; Parthasarathi, R.; Senthilnathan, P.; Maheshkumar, G.

2008-01-01

Background: Familial adenomatous polyposis is a hereditary disease characterized by the presence of thousands of colonic adenomas, which, if untreated, invariably undergo malignant transformation. Because this disease manifests at a young age, the laparoscopic approach to perform surgery would be desirable due to its cosmetic benefits. We describe our experience with this procedure and review the literature on the topic. Methods: This is a case series of 15 patients who underwent restorative proctocolectomy with ileo-anal pouch anastomosis for familial adenomatous polyposis between 2000 and 2007. The salient operative steps are described. Results: There were 9 males and 6 females, 32 to 52 years of age, with an average age of 44.8 years. The median body mass index was 21.5 (range, 17 to 28). Rectal cancer was already present in 4 patients at the time of diagnosis. The median operating time was 225 minutes. Mean blood loss was 60mL, with none of the patients requiring perioperative blood transfusion. None of the surgeries required conversion to the open approach. Bowel function resumed on the second postoperative day in 12 patients and on the third postoperative day in 3 patients. The median hospital stay was 8 days. Postoperatively, there was no mortality and no serious morbidity. Conclusion: Laparoscopic restorative proctocolectomy with ileal pouch anal anastomosis is a feasible surgery for familial adenomatous polyposis, and considering its cosmetic benefit, is a desirable option for this group of predominantly young patients.

Multiple pathways regulate the complex process of endodermal development, including the Bone morphogenetic protein (Bmp) pathway. However, the role of Bmp signaling in pouch morphogenesis is poorly understood. Using genetic and chemical inhibitor approaches, we show that pouch morphogenesis requires Bmp signaling from 10-18 h post-fertilization, immediately following gastrulation. Blocking Bmp signaling during this window results in morphological defects to the pouches and craniofacial skeleton. Using genetic chimeras we show that Bmp signals directly to the endoderm for proper morphogenesis. Time-lapse imaging and analysis of reporter transgenics show that Bmp signaling is necessary for pouch outpocketing via the Fibroblast growth factor (Fgf) pathway. Double loss-of-function analyses demonstrate that Bmp and Fgf signaling interact synergistically in craniofacial development. Collectively, our analyses shed light on the tissue and signaling interactions that regulate development of the vertebrate face. © 2016. Published by The Company of Biologists Ltd.

There are no published studies on the impact of peripouch fat on pouch outcomes in inflammatory bowel disease (IBD) patients. Patients with pelvic MRI-DIXON scans from our prospectively maintained Pouch Database between 2002 and 2016 were evaluated. Peripouch fat area was measured on MRI-DIXON-F images at the middle height level of the pouch (area M) and the highest level of the pouch (area H). Of all 1863 patients in the database, 197 eligible patients were included in this study. The median of area M was 52.4 cm2, so the 197 patients were classified into 2 groups: group 1 (Area-M <52.4 cm2) and group 2 (Area-M ≥52.4 cm2). Compared with group 1, group 2 was found to have thicker perianal fat, more Caucasian and more males. Group 2 also had a higher Area-H, more weight, height, and body mass index, along with greater age at IBD diagnosis, age at pouch construction and pouch age, and a higher frequency of total pouch complication (86.7% versus 66.7%, P = 0.001), chronic pouch complication (68.4% versus 51.5%, P = 0.016), and chronic antibiotic-refractory pouchitis (16.3% versus 7.1%, P = 0.043). Multivariate logistic analysis showed that Area-M was an independent risk factor for chronic antibiotic-refractory pouchitis (odds ratio [OR]: 1.025; 95% confidence interval [CI]: 1.007-1.042, P = 0.005). The 22 patients with 2 or more pelvic MRI-DIXON scans were further classified into 2 groups by the change from the initial to latest MRI-DIXON scans. Patients with Area-M increase ≥10% and Area-M/height increase ≥10% were found to have shorter pouch survivals than those with increase <10%. A new method was established for measuring peripouch fat using pelvic MRI-DIXON-F image. Our study suggests that accumulation of peripouch fat may be associated with poor outcomes in selected IBD patients suspected of inflammatory or mechanical disorders of the pouch. Whether this association is causal warrants further investigation.

Retort Pouch had become a choice to preserve foods nowadays, besides the used of the can. Both had their own advantages, and Retort Pouch became more popular for the reason of cheaper and easier to recycle. General Method usually used to estimate the lethality of commercial heat sterilization process. Lethality value wa s used for evaluating the efficacy of the thermal process. This study aimed to find whether different layers of pouch materials affect the lethality value and to find differences lethality in two types of multilayer retort pouch, PET/Aluminum Foil/Nylon/RCPP and PET/Nylon/Modified Aluminum/CPP. The result showed that the different layer arrangement was resulted different Sterilization Value (SV). PET/Nylon/Modified Aluminum/CPP had better heat penetration, implied by the higher value of lethality. PET/Nylon/Modified Aluminum/CPP had the lethality value of 6,24 minutes, whereas the lethality value of PET/Aluminum Foil/Nylon/RCPP was 3,54 minutes.

To examine whether patients with a mature normal pouch [> 1 year post ileostomy closure] have microbial stool characteristics that can predict pouch inflammation. Patients undergoing pouch surgery were recruited prospectively. Microbiota analysis of faecal samples was by 16S rRNA gene pyrosequencing. All patients had a normal pouch at baseline [T1]. Those without pouchitis during the first year of follow-up [T2] comprised the 'Normal Pouch-sustained' group and those who had experienced an episode of pouchitis comprised the 'Pre-Pouchitis' group. Twenty patients were recruited (age 53.6±13.1 years, pouch age [time from ileostomy closure] 8.1±5.1 years). Seven patients developed pouchitis during follow-up [within 265±93.6 days] and they were assigned to the Pre-Pouchitis group at T1: they had a decreased microbial diversity at T1 compared with the Normal Pouch-sustained patients [n = 13]. The Shannon diversity index for the Pre-Pouchitis patients was 3.4 vs 4.23 for the Normal Pouch-sustained patients [p = 0.011]. There were no substantial group differences in high taxonomic levels [order or above]. The genus Ruminococcus was significantly decreased in the Pre-Pouchitis patients' samples compared with those of the Normal Pouch-sustained patients (0.19% vs 0.78%, respectively, false discovery rate [FDR] = 0.05). The linear discriminant analysis with effect size estimation algorithm revealed that Lachnospira and Coprococcus genera were also decreased among Pre-Pouchitis patients compared with Normal Pouch-sustained patients [0.6% vs 1.95% and 2.1% vs 4%, respectively]. Patients with a normal mature pouch may be predisposed to acute pouchitis when faecal microbial diversity and certain microbial groups are decreased. These findings may aid in risk stratification of those patients. Copyright © 2016 European Crohn’s and Colitis Organisation (ECCO). Published by Oxford University Press. All rights reserved.

An animal model was proposed to clarify the difference in occurrence of enterocolitis in congenital aganglionosis. When gaseous distention of the colon was localized to the rectosigmoid area, enterocolitis never occurred. On the contrary, when it involved the left colon, enterocolitis occurred in 13 of 15 patients. Intestinal blood flow rates were simultaneously measured in the left colon and rectum of six dogs by using labeled microspheres and expressed in function of the intraluminal pressure. Results show that for elevated values of intraluminal pressure, blood flow was significantly lower in the left colon than in the rectum. These results may explain why ischemia and necrosis occurred more frequently in the left colon than in the rectum.

Microfluidic cassettes ("chips") for processing and analysis of clinical specimens and other sample types facilitate point-of-care (POC) immunoassays and nucleic acid based amplification tests. These single-use test chips can be self-contained and made amenable to autonomous operation-reducing or eliminating supporting instrumentation-by incorporating laminated, pliable "pouch" and membrane structures for fluid storage, pumping, mixing, and flow control. Materials and methods for integrating flexible pouch compartments and diaphragm valves into hard plastic (e.g., acrylic and polycarbonate) microfluidic "chips" for reagent storage, fluid actuation, and flow control are described. We review several versions of these pouch chips for immunoassay and nucleic acid amplification tests, and describe related fabrication techniques. These protocols thus offer a "toolbox" of methods for storage, pumping, and flow control functions in microfluidic devices.

The serologic status of patients with ulcerative colitis (UC) who develop postoperative pouchitis was compared with that of patients with Crohn's disease (CD) and unoperated patients with UC. Pouch patients were stratified into normal pouch, acute/recurrent acute pouchitis, and chronic pouchitis/Crohn's-like disease of the pouch groups. Antibodies against glycans associated with CD (anti-Saccharomyces cerevisiae, anti-laminaribioside, anti-chitobioside, and anti-mannobioside carbohydrate antibodies [ASCA, ALCA, ACCA, and AMCA, respectively]) were detected and correlated with type of inflammatory bowel disease and pouch behavior. A total of 501 patients with inflammatory bowel diseases were recruited: 250 (50%) CD, 124 (24.7%) unoperated UC, and 127 (25.3%) UC-pouch. At least 1 positive antibody was detected in 77.6% CD, 52.0% UC-pouch and 33.1% unoperated UC (P < 0.0001 for all). ACCA and AMCA prevalence in CD, UC-pouch and unoperated patients with UC were 33.2%, 24.4%, and 16.9% (P = 0.003 for all) and 35.2%, 26.8%, and 7.3%, respectively (P < 0.0001 for all). ALCA and ASCA were more prevalent in patients with CD than unoperated UC and UC-pouch patients. A longer interval since pouch surgery was associated with inflammatory pouch behavior: 12.45, 11.39, and 8.5 years for acute/recurrent acute pouchitis, chronic pouchitis/Crohn's-like disease of the pouch, and normal pouch, respectively, P = 0.01 for all. The prevalence of the CD-associated anti-glycan antibodies ACCA and AMCA is significantly increased in UC-pouch patients, suggesting that pouch surgery may trigger differential immune responses to glycans. The finding that the serology of UC-pouch patients shares similarities with that of patients with CD supports the notion that those 2 inflammatory bowel diseases share a common pathogenic pathway.

The purpose of this study was to describe the MR enterography (MRE) appearance of inflammation of the ileoanal pouch after ileal pouch-anal anastomosis (IPAA) surgery and to correlate it with pouch endoscopic and histopathologic findings. All MRE studies performed between October 1, 2007, and September 30, 2013, for patients who had previously undergone IPAA (n = 54) were retrieved. After review of medical records, the patients who underwent MRE, pouch endoscopy, and biopsy within 90 days (14 men, 14 women; mean age, 42.2 years; range, 24-67 years) were selected for inclusion in the study. Two blinded MRI radiologists in consensus retrospectively evaluated MRE studies for multiple MRI features. Two MRI scores were then calculated: an active and a composite inflammation score. A gastroenterologist retrospectively reviewed the pouch endoscopic images, and a pathologist reviewed the slides; both of these investigators were blinded. Both MRI scores were correlated with the pouch endoscopic and histopathologic findings. The composite MRI score had strong positive correlation with the endoscopic score (r = 0.61; p = 0.0005) but weak positive correlation with the histopathologic score (r = 0.31; p = 0.10, not statistically significant). The active inflammation MRI score had moderate positive correlation with the endoscopic score (r = 0.57; p = 0.0017) and weak positive correlation with the histopathologic score (r = 0.20; p = 0.31, not statistically significant). An MRI score ≥ 4 indicated the best results, with sensitivity of 86%, specificity of 79%, positive predictive value of 80%, negative predictive value of 85%, and accuracy of 82% for pouch inflammation. A positive likelihood ratio of 4.00 and negative likelihood ratio of 0.18 were obtained. In patients who have undergone IPAA surgery, the MRE findings strongly correlate with the pouch endoscopic findings with high sensitivity and positive predictive value for pouch inflammation. Therefore, MRE is a useful

Although the clinical results of Brooke ileostomy are good, patients are permanently incontinent of stool and gas. Alternative operations designed to restore enteric continence, such as ileal pouch-anal anastomosis, must not only be as safe and effective as Brooke ileostomy, but should provide an improved quality of life in order to establish long-term acceptability. Ileal pouch-anal anastomosis has been performed safely and good functional results have been reported. The quality of life after ileal pouch-anal anastomosis, however, has not been documented. Two hundred ninety-eight ileal pouch patients and 406 Brooke ileostomy patients who had the operations performed for chronic ulcerative colitis or familial adenomatous polyposis formed the basis of the study. After adjusting for age, diagnosis, and reoperation rate, logistic regression analysis of performance scores in seven different categories was used to discriminate between operations. Median follow-up was longer in Brooke ileostomy patients than in ileal pouch patients (104 months vs. 47 months, respectively), and Brooke ileostomy patients were slightly older (38 years vs. 32 years). A great majority of patients in each group were satisfied (93% Brooke ileostomy; 95% ileal pouch-anal anastomosis). Thirty-nine per cent of Brooke ileostomy patients, however, desired a change in the type of ileostomy they had. At 47 months, ileal pouch patients had a median of 5 stools per day and 1 at night, 77% did not experience any daytime incontinence, while 22% reported occasional spotting. In each performance category, the performance score discriminated between operations, with the probability of having had an ileal pouch-anal anastomosis operation increasing with improvement in performance scores (p less than 0.05). We concluded that after ileal pouch-anal anastomosis, patients experienced significant advantages in performing daily activities compared to patients with Brooke ileostomy and thus may experience a better

Pouchitis is often diagnosed based on symptoms and empirically treated with antibiotics (treat-first strategy). However, symptom assessment alone is not reliable for diagnosis, and an initial evaluation with pouch endoscopy (test-first strategy) has been shown to be more accurate. Cost-effectiveness of these strategies has not been compared. The aim of this study was to compare cost-effectiveness of different clinical approaches for patients with symptoms suggestive of pouchitis. Pouchitis was defined as pouchitis disease activity index scores > or =7. The frequency of pouchitis in symptomatic patients with ileal pouch was estimated to be 51%; the efficacy for initial therapy with metronidazole (MTZ) and ciprofloxacin (CIP) was 75% and 85%, respectively. Cost estimates were obtained from Medicare reimbursement data. Six competing strategies (MTZ trial, CIP trial, MTZ-then-CIP trial, CIP-then-MTZ trial, pouch endoscopy with biopsy, and pouch endoscopy without biopsy) were modeled in a decision tree. Costs per correct diagnosis with appropriate treatment were $194 for MTZ trial, $279 for CIP trial, $208 for MTZ-then-CIP trial, $261 for CIP-then-MTZ trial, $352 for pouch endoscopy with biopsy, and $243 for pouch endoscopy without biopsy. Of the two strategies with the lowest cost, the pouch endoscopy without biopsy strategy costs $50 more per patient than the MTZ trial strategy but results in an additional 15 days for early diagnosis and thus initiation of appropriate treatment (incremental cost-effectiveness ratio $3 per additional day gained). The results of base-case analysis were robust in sensitivity analyses. Although the MTZ-trial strategy had the lowest cost, the pouch endoscopy without biopsy strategy was most cost-effective. Therefore, based on its relatively low cost and the avoidance of both diagnostic delay and adverse effects associated with unnecessary antibiotics, pouch endoscopy without biopsy is the recommended strategy among those tested for the

The experimental system of Taenia crassiceps cysticerci infection in BALB/c mice is considered to be the most representative model of cysticercosis. In our work, mice were sacrificed 7 and 30days after infection, and pouch fluid was collected to determine the number of accumulated cells and the concentrations of IFNγ, IL-2, IL-4, IL-6, IL-10 and nitric oxide. The injection of 50 nonbudding cysticerci into normal mouse dorsal air pouches induced a high level of IFNγ and nitric oxide production relative to the parasite load. The air pouch provides a convenient cavity that allows studying the cellular immunological aspects of the T. crassiceps parasite. The nonbudding cysticerci recovered from the air pouches contained cells that can reconstitute complete cysts in the peritoneal cavity of mice. In conclusion, these results demonstrate that the air pouch model is an alternative tool for the evaluation of the immune characteristics of T. crassiceps infection. Copyright © 2013 Elsevier Inc.

During ontogeny, part of Rathke's pouch, a physiologically superior pouching of the stomodeal ectoderm, may remain, forming the usual anomaly known as Rathke's cleft cyst. More rarely, however, the entire pouch (i.e., the craniopharyngeal canal) remains, resulting in transsphenoidal meningoencephalocele. This study is aimed to provide a better understanding of the pathogenesis. We histologically evaluated the inferior protrusion of the putative hypophysial fossa in 35 embryonic and fetal heads, respectively (15 at 5-8 weeks and 20 at 12-16 weeks of gestation). In 3 of the 35 specimens, we observed a complete cleft originating from the adenohypophysis, passing through the sphenoid and connecting with the pharyngeal epithelium or pharyngobasilar fascia. In another 18 specimens, we observed a duct-like structure protruding from the fossa and ending in the sphenoid. The sellar protrusion contained vein-like structures and debris of red blood cells. The protrusion was located on the anterior or anterosuperior side of the notochord. No ossification center was observed around the sellar region of the embryos. Although ossification occurred in 12 of the 20 fetuses, nine of the latter showed no evidence of cleft or protrusion, indicating that the incidence of Rathke's pouch remnant was lower in the fetuses (11/20) than in the embryos (11/15). Rathke's pouch may be closed by ossification of the sphenoid, but increased cell proliferation and/or large amounts of degenerated veins may provide a structure resistant to the mechanical pressure caused by ossification.

The psychological impact stoma surgery can have on an individual is well documented within the literature (White and Hunt, 1997; Borwell, 2009; Williams, 2005; Brown, 2005). For many years, surgeons have explored and developed innovations in surgical techniques, in particular restorative procedures with a view of preventing permanent stoma formation; ileal anal pouch (IAP) now being the surgical procedure of choice for treatment of ulcerative colitis (UC) and familial adenomatous polyposis (FAP). However, high morbidity rates are associated with pouch longevity (Castillo et al 2005; Nessar and Wu, 2012) and once removed can lead to a high-output ileostomy with risks of electrolyte imbalance and malabsorption. This then creates the dilemma of whether the Kock pouch (KP) should be offered as a surgical option. This article offers a historical perspective of the KP and its place in the surgical management of UC and FAP. This article also presents results from a recent audit funded by the Ileostomy Association (IA), highlighting how patients manage their KP and the importance of maintaining bowel control and being free of an incontinent stoma as a means of coming to terms with their condition.

Beyond the brotherhood: Skoal Bandits' role in the evolution of marketing moist smokeless tobacco pouches.

Since 2006, "snus" smokeless tobacco has been sold in the U.S.. However, U.S. Smokeless Tobacco (USST) and Swedish Match developed and marketed pouched moist snuff tobacco (MST) since 1973. Analysis of previously secret tobacco documents, advertisements and trade press. USST partnered with Swedish Match, forming United Scandia International to develop pouch products as part of the "Lotus Project." Pouched MST was not commonly used, either in Sweden or the U.S. prior to the Lotus Project's innovation in 1973. The project aimed to transform smokeless tobacco from being perceived as an "unsightly habit of old men" into a relevant, socially acceptable urban activity, targeting 15-35 year-old men. While USST's initial pouched product "Good Luck," never gained mainstream traction, Skoal Bandits captured significant market share after its 1983 introduction. Internal market research found that smokers generally used Skoal Bandits in smokefree environments, yet continued to smoke cigarettes in other contexts. Over time, pouch products increasingly featured increased flavor, size, nicotine strength and user imagery variation. Marlboro and Camel Snus advertising mirrors historical advertising for Skoal Bandits, designed to recruit new users and smokers subjected to smokefree places. Despite serious efforts, pouched MST marketing has been unable to dispel its association with traditional smokeless tobacco stereotypes as macho and rural. Public education efforts to discourage new users and dual use of MST and cigarettes should emphasize that "new" pouch products are simply repackaging "old" smokeless tobacco.

The incidence of colonic diverticular disease varies with national origin, cultural background and diet. The frequency of this disease increases with advancing age. Right-sided diverticular disease is uncommon and reported to occur in 1-2% of surgical specimens in European and American series. In contrast the disease is more prevalent and reported in 43-50% of specimens in Asian series. Various lines of evidence suggest this variation may represent hereditary differences. The aim of the study is to report all cases of right sided diverticular disease underwent surgical resection or identified during pathological examination of right hemicoloectomy specimens A retrospective review of all surgical specimens with right sided colonic diverticular disease selected from a larger database of all colonic diverticulosis and diverticulitis surgical specimen reported between January 1993 and December 2010 at the Pathology Department McMaster University Medical Centre Canada. The clinical and pathological features of these cases were reviewed The review identified 15 cases of right colon diverticulosis. The clinical diagnoses of these cases were appendicitis, diverticulitis or adenocarcinoma. Eight cases of single congenital perforated diverticuli were identified and seven cases were incidental multiple acquired diverticuli found in specimen resected for right side colonic carcinomas/large adenomas. Laparotomy or laparoscopic assisted haemicolectomies were done for all cases. Pathological examination showed caecal wall thickening with inflammation associated with perforated diverticuli. Histology confirmed true solitary diverticuli that exhibited in two cases thick walled vessels in the submucosa and muscular layer indicating vascular malformation/angiodysplasia. Acquired diverticuli tend to be multiple and are mostly seen in specimens resected for neoplastic right colon diseases.

In the present study, we found several pharyngeal pouch remnants, such as cystic structures in thymus and parathyroid gland and fossulae extended from the piriform fossa, in the inbred cotton rats maintained at Hokkaido Institute of Public Health (HIS/Hiph) and University of Miyazaki (HIS/Mz). In HIS/Hiph, the fossulae extended from the apex of the piriform fossa into the thyroid glands and were lined with stratified squamous and cuboidal epithelium. Calcitonin-positive C-cells were present within their epithelium in HIS/Hiph. In contrast, the fossulae of HIS/Mz ran outside the thyroid glands toward the parathyroid glands; they were lined with columnar ciliated epithelium and a few goblet cells, but had no C-cells, which was consistent with the cystic structures in the thymus and the parathyroid gland. These results indicated that the fossulae were a remnant of the ultimobranchial body in HIS/Hiph and of the thymopharyngeal duct in HIS/Mz. Thus, the fossulae of the piriform fossa resembled the piriform sinus fistula in human. In conclusion, cotton rats frequently possessed pharyngeal pouch remnants, including the piriform sinus fistula, and therefore, might serve as a novel model to elucidate the mechanisms of pharyngeal pouch development.

Inflammatory complications including chronic refractory pouchitis and Crohn's disease (CD)-like complications of the pouch are common complications after ileal pouch-anal anastomosis (IPAA) following colectomy for ulcerative colitis (UC). We performed a systematic review and meta-analysis to evaluate the efficacy of anti-TNF therapy in distinguishing patients with chronic refractory pouchitis from those with CD-like complications of the pouch. We performed a systematic literature search to identify articles and abstracts reporting anti-TNF agents efficacy in treating inflammatory complications of the pouch after IPAA for UC. Short-term and long-term remissions were evaluated at 8 weeks 95%CI[5-10] and 12 months 95%CI[12-18.5], respectively. We identified 21 articles and 3 abstracts including 313 patients treated either with infliximab (n = 194) or adalimumab (n = 119) for inflammatory complications of the pouch. The rates of short-term and long-term clinical remission were 0.50 (95%CI [0.37-0.63]; I2 = 0.57) and 0.52 (95%CI[0.39-0.65]; I2 = 0.59), respectively. The rate of remission after anti-TNF induction therapy seemed to be higher in CD-like complications of the pouch 0.64 (95%CI[0.5-0.77]; I2 = 0.18), compared to refractory pouchitis 0.10 (95%CI [0.00-0.35]; I2 = 0.00) (P = 0.06), whereas no such difference appeared after long-term maintenance therapy 0.57 (95%CI[0.43-0.71]; I2 = 0.32) and 0.37 (95%CI [0.14-0.62]; I2 = 0.47), respectively (P = 0.57). Sensitivity analyses suggested no difference in outcomes. No significant publication bias has been detected. Anti-TNF agents have a clear trend to have higher and faster efficacy in CD-like complications of the pouch compared to refractory pouchitis, highlighting the need to differentiate these two entities both in daily practice and clinical trials. © 2018 Crohn’s & Colitis Foundation of America.

Bile acid absorption was investigated using 75Se Taurohomocholate (SeHCAT) in controls and patients who had undergone total colectomy with either conventional ileostomy or pouch-anal anastomosis for ulcerative colitis or adenomatous polyposis. Whole-body retention of SeHCAT after 168 hours was greater in the controls than the patients who had undergone colectomy (P less than .05). Retention of SeHCAT did not differ significantly between patients with an ileostomy and patients with pouch-anal anastomosis, but patients with an ileostomy and ileal resection of more than 20 cm retained less SeHCAT than patients with a pouch-anal anastomosis (P less than .01). Analysis of fecal bile acids from ileostomies and pouches showed that bacterial metabolism of primary conjugated bile acids was greater in patients with a pouch. It was concluded that bile acid absorption was not significantly impaired by construction of a pouch compared with conventional ileostomy, but bacterial metabolism of bile acids was greater in the pouches.

Birth rates in males with ulcerative colitis and ileal pouch-anal anastomosis have not been studied. This study aimed to estimate birth rates in males and females with ulcerative colitis and study the impact of ileal pouch-anal anastomosis. This was a retrospective registry-based cohort study that was performed over a 30-year period. Records for parenting a child from the same period were cross-linked with patient records, and birth rates were calculated using 15 through 49 years as age limits. All data were prospectively registered. All patients with ulcerative colitis and ulcerative colitis with ileal pouch-anal anastomosis between 1980 and 2010 were identified in Danish national databases. The primary outcomes measured were birth rates in females and males with ulcerative colitis and ulcerative colitis with ileal pouch-anal anastomosis. We included 27,379 patients with ulcerative colitis (12,812 males and 14,567 females); 1544 had ileal pouch-anal anastomosis (792 males and 752 females). Patients with ulcerative colitis have slightly reduced birth rates (males at 40.8 children/1000 years, background population 43.2, females at 46.2 children/1000 years, background population 49.1). After ileal pouch-anal anastomosis, males had increased birth rates at 47.8 children/1000 years in comparison with males with ulcerative colitis without ileal pouch-anal anastomosis (40.5 children/1000 years), whereas females had reduced birth rates at 27.6 children/1000 years in comparison with females with ulcerative colitis without ileal pouch-anal anastomosis (46.8 children/1000 years). Only birth rates were investigated and not fecundability. Furthermore, there is a question about misattributed paternity, but this has previously been shown to be less than 5%. Ulcerative colitis per se has little impact on birth rates in both sexes, but ileal pouch-anal anastomosis surgery leads to a reduction in birth rates in females and an increase in birth rates in males. This has clinical

Surgical considerations in FAP-related pouch surgery: Could we do better?

The ileoanal pouch has become the standard restorative procedure of choice for patients with the classical phenotype in FAP (familial adenomatous polyposis) and also for ulcerative colitis (UC). Whilst we tend to encounter descriptive analyses comparing functional outcome, fertility and quality of life (QOL) between series in literature, there may be an urgent need to discuss the subtle technical modifications that may be pivotal for improving long-term QOL in FAP patients. Our aim is to review the current literature and discuss the aspects of ileal pouch-anal anastomosis that may require specific reevaluation for FAP. Surgical strategies aimed at minimizing post-interventional desmoid growth is one of the most important aspects. For this study, the following topics of interest were selected: Timing of surgery, IRA or ileoanal pouch for classical FAP, laparoscopic or conventional surgery, TME or mesenteric dissection, preservation of the ileocolic vessels, handsewn or double-staple anastomosis, shape and size of pouch, protective ileostomy, Last and definitely not least: how to manage desmoid plaques or desmoids at the time of prophylactic surgery. For the depicted technicalities of the procedure, a review of recent literature was performed and evaluated. For the topics selected, only sparse reference in literature was identified that was focused on the specific condition situation of FAP. Almost all pouch literature focusses on the procedural aspects, and FAP patients are always a very minor number. Therefore it becomes obvious that the specific entity is not adequately taken into account. This is a serious bias for identification of important steps in the procedure that may be beneficial for patients with either of the diseases. The results of this study demonstrate that several technical differences for construction of ileoanal pouches in FAP patients deserve more attention and prospective evaluation-perhaps even randomized trials.

A portable, small footprint, light, general purpose analyzer (processor) to control the flow in immunoassay cassettes and to facilitate the detection of test results is described. The durable analyzer accepts disposable cassettes that contain pouches and reaction chambers for various unit operations such as hydration of dry reagents, stirring, and incubation. The analyzer includes individually controlled, linear actuators to compress the pouches in the cassette, which facilitates the pumping and mixing of sample and reagents, and to close diaphragm-based valves for flow control. The same types of actuators are used to compress pouches and actuate valves. The analyzer also houses a compact OEM scanner/reader to excite fluorescence and detect emission from labels. The analyzer is hydraulically isolated from the cassette, reducing the possibility of cross-contamination. The analyzer facilitates programmable, automated execution of a sequence of operations such as pumping and valving in a timely fashion, reducing the level of expertise required from the operator and the possibility for errors. The analyzer’s design is modular and expandable to accommodate cassettes of various complexities and additional functionalities. In this paper, the utility of the analyzer has been demonstrated with the execution of a simple, consecutive, lateral flow assay of a model biological system and the test results were detected with up converting phosphor labels that are excited at infrared frequencies and emit in the visible spectrum.

A small proportion of infants with oesophageal atresia (OA) are thought to have a proximal tracheoesophageal fistula (TOF). Failure to recognize these can hamper mobilization of the upper pouch and lead to life-threatening episodes of aspiration once oral feeding starts. We reviewed our experience of upper pouch fistulae to identify characteristic features of proximal TOF. A retrospective review of TOF/OA patient notes and bronchoscopy photographs and videos, identified from our database from 01/01/2006 to 12/31/2015, was performed. Eight (6.1%) infants were identified (M:F 5:3) from a total population of 131 newly diagnosed TOF/OA infants during the period. Their median gestational age was 33 (range 28-39) weeks, and median birth weight was 1647g (range 1100-3400g). Five were initially diagnosed with pure OA and 3 with a distal TOF. All patients underwent rigid bronchoscopy at the initial surgery but only one proximal fistula was identified. The 7 missed proximal fistulae were subsequently found either during on-table oesophagograms for gap assessment (n=2), at the time of thoracotomy when mobilizing the upper pouch (n=3), or during subsequent bronchoscopy for symptoms post OA repair (n=2). Two patients needed a further operation to divide the fistula. Review of the bronchoscopy videos identified four characteristic differences between upper and lower pouch fistulae. Proximal fistulae are found just distal to the vocal cords, are very small, often no more than a pit, do not open and close with ventilation, and are best identified by insufflation of the esophagus. Upper pouch fistulae are relatively easy to miss because of different characteristics compared with H-type or distal fistulae that have not previously been mentioned in the literature. level IV.

Clinico-Radiological Diagnosis of Isolated Congenital Esophageal Stenosis in a Preterm Neonate

A 2-day-old preterm female neonate weighing 1.6 kg and having excessive frothing from mouth was investigated for suspected esophageal atresia and tracheoesophageal fistula. X-ray findings of an unusually low-ending upper pouch (up to T8 level) and the absence of gas in abdomen lead to suspicion of an unusual variety of esophageal atresia. Hence unlike the usual management of pure esophageal atresia, in terms of esophagostomy and gastrostomy in neonatal period, right thoracotomy was performed allowing successful primary anastomosis. A high index of suspicion on the basis of radiological picture led to early diagnosis of a rare anomaly like congenital esophageal stenosis and successful management of this low birth weight baby.

The patient was a 63-year-old man,who first visited our hospital with the chief complaints of left lower quadrant pain and abdominal distension that had developed around November 13, 2004. On close examination, he was diagnosed with sigmoid colon cancer, multiple liver metastasis, and subileus due to a lung metastasis. His operation took place on December 12 of the same year. Intraoperatively, the sigmoid colon was firmly fixed to the retroperitonium, there was a hard node in the pouch of Douglas, and that part of the jejunum was involved. The lesion was judged to be unresectable,and thus loop colostomy, partial jejunectomy and gastrojejunostomy were performed. After the surgery,the patient was treated with 4 courses of therapy with oral Leucovorin (LV, 75 mg) +oral tegafur/uracil (UFT, 400 mg). As a result, the tumor marker levels decreased markedly, the lung metastasis was no longer observed and the liver metastases became smaller. Therefore, a second-look operation was performed on May 30, 2005. This time it was relatively easy to free the sigmoid colon. The node in the pouch of Douglas was no longer observed, and there were only 2 metastatic lesions in the liver (1 each in S 2 and S 6). Sigmoidectomy and partial hepatectomy were performed, and the stoma was closed. The patient made good progress after the operation and was discharged on the 11 th POD. At present he is receiving chemotherapy with UFT+oral LV as an outpatient. As this therapy is relatively easy to perform and imposes only a small burden on patients,we think that it may be effective not only as adjuvant chemotherapy but also as neoadjuvant chemotherapy in some patients.

Cancer in an unexpected site post pouch surgery for familial adenomatous polyposis (FAP).

Familial Adenomatous Polyposis (FAP) is a hereditary condition characterized by multiple colorectal adenomatous polyps. FAP is the most common adenomatous polyposis syndrome. Restorative proctocolectomy is the most commonly performed surgical procedure performed for patients suffering from FAP with different options for anastomosis, namely ileorectal anastomosis (IRA) or ileal pouch anal anastomosis (IPAA). The occurrence of adenomas is a common finding during follow up and surveillance post surgery for these patients. Although there are a few cases of carcinoma that were namely at the anal transitional zone (ATZ), there are only a few cases of ileal pouch related adenocarcinoma reported. This work has been reported in line with the SCARE criteria (Agha et al., 2016) [1]. We report a case of a 34-year-old man diagnosed with FAP who underwent proctocolectomy with IPAA, and subsequently referred to our center, who, despite appropriate measures and surveillance, developed adenocarcinoma in the ileal pouch. Restorative proctocolectomy for Familial Adenomatous Polyposis (FAP) is the mainstay of treatment. There are different surgical options, each with its own set of advantages and disadvantages. The most favored option is proctocolectomy with ileal pouch anal anastomosis (IPAA) due to because it involves resection of the rectum. Despite these interventions, adenomas and/or carcinomas have been reported on follow up post surgery. Although the risk of developing adenomas or carcinomas in the ileal pouch post proctocolectomy with IPAA is low it should not be neglected as cancer occurrence or recurrence is unpredictable even with appropriate measures.

The need for test systems for nanoparticle biocompatibility, toxicity, and inflammatory or adaptive immunological responses is paramount. Nanoparticles should be free of microbiological and chemical contaminants, and devoid of toxicity. Nevertheless, in the absence of contamination, these particles may still induce undesired immunological effects in vivo, such as enhanced autoimmunity, hypersensitivity reactions, and fibrosis. Here we show that artificial particles of specific sizes affect immune cell recruitment as tested in a dermal air pouch model in mice. In addition, we demonstrate that the composition of nanoparticles may influence immune cell recruitment in vivo. Aside from biophysical characterizations in terms of hydrodynamic diameter, zeta potential, concentration, and atomic concentration of metals, we show that – after first-line in vitro assays – characterization of cellular and molecular effects by dermal air pouch analysis is straightforward and should be included in the quality control of nanoparticles. We demonstrate this for innate immunological effects such as neutrophil recruitment and the production of immune-modulating matrix metalloproteases such as MMP-9; we propose the use of air pouch leukocytosis analysis as a future standard assay.

The coexistence of congenital left ventricular aneurysm and abnormal cardiac trabeculation with gene mutation has not been reported previously. Here, we report a case of coexisting congenital left ventricular aneurysm and prominent left ventricular trabeculation in a patient with LIM domain binding 3 gene mutation. A 30-year-old Asian man showed paroxysmal sinus tachycardia and Q waves in an electrocardiogram health check. There were no specific findings in physical examinations and serological tests. A coronary-computed tomography angiography check showed normal coronary artery and no coronary stenosis. Both left ventricle contrast echocardiography and cardiac magnetic resonance showed rare patterns of a combination of an apical aneurysm-like out-pouching structure with a wide connection to the left ventricle and prominent left ventricular trabecular meshwork. High-throughput sequencing examinations showed a novel mutation in the LDB3 gene (c.C793>T; p.Arg265Cys). Our finding indicates that the phenotypic expression of two heart conditions, congenital left ventricular aneurysm and prominent left ventricular trabeculation, although rare, can occur simultaneously with LDB3 gene mutation. Congenital left ventricular aneurysm and prominent left ventricular trabeculation may share the same genetic background.

To describe the multidetector-row computed tomography enterographic (MD-CTE) features of the ileal-anal pouch after ileal pouch anal anastomosis (IPAA) surgery and correlate them with pouch endoscopy and histopathologic findings. All MD-CTE examinations performed on patients who underwent IPAA from July 1, 2005 to December 1, 2010 (n = 35; 16 [45.7%] men; mean age, 37.7 years; age range, 22-72 years) were retrospectively evaluated in consensus by 2 radiologists. All studies were evaluated for the presence of multiple imaging features. Two radiographic scores were then calculated: a total radiographic score and a radiographic active inflammation score. In patients who underwent MD-CTE, pouch endoscopy, and biopsy within 30 days (n = 13), both scores were correlated with findings on pouch endoscopy and histopathology. Of the 35 patients, 33 (94%) had at least one MD-CTE finding of active or chronic pouch inflammation and 27 patients (77%) had at least one MD-CTE finding of active pouch inflammation. Of the 13 patients who underwent endoscopy and biopsy, the total radiographic score demonstrated a strong positive correlation with endoscopic score (r = 0.81; P = 0.001) and a moderate positive correlation with histopathologic score (r = 0.56; P = 0.047). The radiographic active inflammation score demonstrated a strong positive correlation with endoscopic score (r = 0.83; P = 0.0004), but only a weak nonsignificant positive correlation with histopathologic score (r = 0.492, P = 0.087). In patients who had IPAA surgery, findings on MD-CTE correlate positively with findings on pouch endoscopy and histopathology and are sensitive measures for pouch inflammation with high positive predictive value. Thus, MD-CTE can be a useful noninvasive test in the early evaluation of symptomatic patients.

A potential complication in women after ileal pouch-anal anastomosis (IPAA) is sexual impairment and reduced fertility. The aim was to evaluate sexual function and fertility after IPAA. All female patients who underwent an IPAA between 2004 and 2013 were retrospectively included. Sexual function, fertility, and continence were explored by the female sexual function index (FSFI), telephonic interview, and Wexner's score. Among 127 women included, 93 responded to the questionnaires (73.2%). Seventy five were sexually active, and 48 (64%) had normal sexual function (FSFI > 26). In univariate analysis, there was a significant relationship between ulcerative colitis (p = 0.0161), age > 40 years (p = 0.01311), number of bowel movements (p = 0.0238), nocturnal pouch activity (p = 0.0094), use of loperamide (p = 0.0283), and existence of sexual dysfunction. After multivariate analysis, age and nocturnal pouch activity were associated with a worse sexual function (p = 0.0235, OR = 3.3 (1.2-9.9) and p = 0.0094, OR = 4.1 (1.4-13.5)). Of 16 patients who wished to have children, 10 (63%) became pregnant without recourse to in vitro fertilization, of whom 3 had two or more pregnancies. In total, there were 13 children born after IPAA. The mean time between the first pregnancy and surgery was 24.8 ± 22 months. At 12 and 24 months after cessation of contraception, 57 and 67% had at least one pregnancy. While sexual function is impaired in a limited number of patients, the impact of surgery can be regarded as modest. Age and nocturnal pouch activity were some independent factors of worse sexual function. The risk of infertility should not preclude consideration of IPAA as a treatment option.

Mature cystic teratoma is a germ cell tumor of the ovaries and is often observed in clinical practice. However, extragonadal teratomas are rare tumors and have been reported outside the ovaries, (e.g., in the greater omentum). The mechanism underlying the development of extragonadal teratomas remains unknown. We encountered a case of extragonadal teratoma in the pouch of Douglas that appeared to be a parasitic dermoid cyst. From our experience and the literature review, we discuss the potential mechanism leading to the development of extragonadal teratomas. A 41-year-old nonpregnant woman was referred to our department due to myoma and anemia. A 4-cm asymptomatic mass in the pouch of Douglas was observed, and the patient was diagnosed with ovarian mature cystic teratoma. She underwent laparoscopic surgery, and intraoperative findings revealed that the fallopian tube was injured and torn, and a residual small ovary was observed in the left side of the ovary. A tumor measuring approximately 4 cm observed in the pouch of Douglas was extracted without rupturing. The tumor was diagnosed as a parasitic dermoid cyst by macroscopic and histopathological findings. Auto-amputation could be the underlying mechanism that leads to an isolated parasitic dermoid cyst in the pouch of Douglas. Copyright © 2015 AAGL. Published by Elsevier Inc. All rights reserved.

It is well established that ileoanal pouch-related septic complications (PRSC) increase the risk of pouch failure. There are a number of publications that describe the management of early PRSC in ulcerative colitis (UC) in small series. This article aims to systematically review and summarise the relevant contemporary data on this subject and provide an algorithm for the management of early PRSC. A systematic review was undertaken in accordance with PRISMA guidelines. Studies published between 2000 and 2017 describing the clinical management of PRSC in patients with UC within 30 days of primary ileoanal pouch surgery were included. A qualitative analysis was undertaken due to the heterogeneity and quality of studies included. 1157 abstracts and 266 full text articles were screened. Twelve studies were included for analysis involving a total of 207 patients. The studies described a range of techniques including image-guided, endoscopic, surgical and endocavitational vacuum methods. Based on the evidence from these studies, an algorithm was created to guide the management of early PRSC. The results of this review suggest that although successful salvage of early pouch related septic complications is improving there is little information available relating to methods of salvage and outcomes.. Novel techniques may offer increased chance of salvage but comparative studies with longer follow-up are required. This article is protected by copyright. All rights reserved.

We aimed to evaluate postoperative fecal incontinence scales of children who underwent laparoscopic proctocolectomy and ileal J-pouch anastomosis for familial adenomateous polyposis (FAP) and inflammatory bowel disease (IBD). Fecal incontinence scores were collected at 3 months post-surgery. A retrospective chart review was also performed to obtain the demographic data and operative technical details. The postoperative Wexner Fecal Incontinence Score was 0 in 9 of 11 patients and satisfactory in the remaining two. None of the children had a major complication. Even though the presented study does not have any comparable data, it seems that laparoscopic total proctocolectomy with ileal J-pouch anal anastomosis (TP IPAA) might be the best choice of surgery because it provides good continence with low complication rates.

An unusual colon atresia in a calf: at the junction of the distal loop and transverse colon. A brief overview

PubMed Central

Lombardero, Matilde; Yllera, María del Mar

2014-01-01

Congenital defects are those abnormalities present at birth. During embryogenesis, many anomalies can occur. The primitive gut tube lengthens quickly and rotates, allowing the gastrointestinal tract acquire its final position and orientation. Because the colon of large animals is complex, most changes occur in this segment. Thus, in ruminants, colon atresia is the most frequent malformation, affecting mainly ascending colon, at the level of the spiral loop. There are no previous references about a very atypical colon atresia at the junction of distal loop and transverse colon, such we have described in a 5-day-old calf, after a history of abdominal distention and absence of feces at birth, even with a patent anal opening. Atresia coli was detected at distal position of the typical colon atresia, at the junction of distal loop and transverse colon. In addition, the distal blind end was bent into a U-shape supported by the mesocolon. Besides the anatomical findings of this worthwhile atresia coli we discuss its possible etiology, in which local factors, such as a compromised blood supply during embryogenesis, are more consistent than genetic factors. Finding out the causes of atresia coli would help to reduce its incidence, lessen animal suffering and economic loss. PMID:25495264

Gastrointestinal duplications are uncommon congenital malformations that can occur anywhere along the gastrointestinal tract. Most cases are recognized before the age of 2 years, and those encountered in adults are rare. We describe here a case of ascending colon duplication in a 20-year-old male that caused intussusception and was treated laparoscopically. Although computed tomography revealed a cystic mass filled with stool-like material, the preoperative diagnosis was a submucosal tumor of the ascending colon. We performed a laparoscopic right colectomy, and the postoperative pathological diagnosis was duplication of the ascending colon, both cystic and tubular components. We conclude that gastrointestinal duplications, although rare, should be considered in the differential diagnosis of all abdominal and submucosal cystic lesions and that laparoscopy is a preferred approach for the surgical treatment of gastrointestinal duplications.

After 100 days of age the O2 consumption rate at low temperatures rose and at about 140 days of age a constant rate was maintained over the full ambient temperature range. 4. Heat transfer from joey to mother commenced after 100 days of age. 5. At 150-180 days of age the rate of O2 consumption at 20° C was approximately 12 times greater than at ages less than 100 days. A thermal neutral zone was established in the range 32-36° C by joeys older than 150 days. 6. At the usual pouch temperature of 36·5° C, O2 consumption per unit wet body weight rose from 12 ml./kg.min at birth to 17 ml./kg.min at the end of pouch life. On a unit dry body weight basis it fell from 120 to 56 ml./kg.min. This decline parallels the decrease in growth rate. PMID:5972171

Acute inflammation was induced by injecting carrageenan into a 6 day old air pouch in mice. Sodium aurothiomalate was then given twice to each of three groups of mice via different routes. It was found that the mice injected intravenously with sodium aurothiomalate showed the most striking reduction in the number of exudate leucocytes in the inflammatory cavity, although the amount of gold found in their inflamed pouch lining tissue was the least. The amount of gold in plasma was highest in the mice injected intravenously with sodium aurothiomalate and the least amount of gold was found in the mice injected directly into the air pouch with sodium aurothiomalate. The amount of gold in the inflamed pouch lining tissue reached its peak at 24 hours after injection and a significant decrease of exudate leucocytes was only seen 24 and 72 hours after injection. The amount of gold in the exudate fluid was negligible at all the times studied. No significant difference was noted in the degree of inflammatory suppression when increasing doses of sodium aurothiomalate were injected into the air pouch. These findings show that there is no direct correlation between the gold concentration in the inflamed tissue and suppression of the inflammatory reactions in the cavity. Chemotactic and phagocytic analysis of leucocytes in the exudate showed that there was a significant suppression of the neutrophil activities in all the mice treated with sodium aurothiomalate. It is therefore concluded that the significant reduction in the number of exudate leucocytes at the carrageenan induced inflammatory site after treatment with sodium aurothiomalate is most likely due to the direct action of gold on the functional activities of circulating neutrophils.

Studies on the physical, chemical, and microbiological qualities of fresh tilapia meat revealed its suitability for the preparation of ready to eat fish curry packed in retort pouches. Studies on the fatty acid profile of tilapia meat suggest fortification with polyunsaturated fatty acid (PUFA) to increase the nutritional value. Based on the commercial sterility, sensory evaluation, color, and texture profile analysis F(0) value of 6.94 and cook value of 107.24, with a total process time of 50.24 min at 116 °C was satisfactory for the development of tilapia fish curry in retort pouches. Thermally processed ready to eat south Indian type tilapia fish curry fortified with PUFA was developed and its keeping quality studied at ambient temperature. During storage, a slight increase in the fat content of fish meat was observed, with no significant change in the contents of moisture, protein, and ash. The thiobarbituric acid (TBA) values of fish curry significantly increased during storage. Fish curry fortified with 1% cod liver oil and fish curry without fortification (control) did not show any significant difference in the levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), during thermal processing and storage. Sensory analysis revealed that fortification of fish curry with cod liver oil had no impact on the quality. Tilapia fish curry processed at 116 °C and F(0) value of 7.0 (with or without fortification of cod liver oil) was fit for consumption, even after a period of 1-y storage in retort pouch. Tilapia is a lean variety of fish with white flesh and therefore an ideal choice as raw material for the development of ready to serve fish products such as fish curry in retort pouches for both domestic and international markets. Ready to eat thermal processed (116 °C and F(0) value of 7.0) south Indian type tilapia fish curry enriched with PUFA and packed in retort pouch was acceptable for consumption even after a storage period of 1 y at ambient

The use of biodegradable polymeric materials has been proposed as an environmentally-friendly alternative to petroleum-based packaging. To extend the shelf life of food products, these bioplastics must possess appropriate barrier properties and food-package stability. In the present study, shelf life analysis of packaged baby formula in biopolymeric, multilayer film, fabricated from poly(lactide) (PLA) and whey protein isolate (WPI), PLA/WPI/PLA and PLA pouches was performed at 4-35  o C and 50-59% relative humidity. Despite the possible sorption of food components into contact PLA surfaces, the results demonstated that the transparency and barrier properties of PLA-based pouches were insignificantly changed over time (P > 0.05), although the films showed a slow rate of color change. The baby formula packaged in PLA/WPI/PLA had a delayed lipid oxidation compared to the sample in the PLA pouch, especially at a higher temperature. The application of WPI in the multilayer structure shifted the shelf life determination factor from lipid oxidation to moisture gain. The results indicate that the PLA/WPI/PLA pouch has good storage stability. The film could be used to package dry food properly at 4-35  o C and 50-59% relative humidity for an extended period of time. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

After Roux-en-Y gastric bypass (RYGB), approximately 10% of patients have insufficient weight loss (excess body mass index loss<50%). Gastric pouch emptying may have a role in weight loss. To compare pouch emptying of patients with poor weight loss and patients with successful weight loss after RYGB. A research-intensive nonacademic hospital and center of expertise in bariatric surgery in the Netherlands METHODS: Female patients were included from among patients with the least (poor weight loss group [P-WL]) and the most weight loss (successful weight loss group [S-WL]) in our center 2 years after RYGB. Pouch emptying scintigraphy was performed after ingestion of a radiolabeled solid meal. Emptying curves, intestinal content (IC) at meal completion and after 15, 30, 45, and 60 minutes, half emptying time, and maximal pouch emptying rate were compared. Five individuals were included in P-WL and 5 in S-WL, on average 2.5 ± .3 years after RYGB. Total weight loss was 18 ± 4.1% in P-WL and 44 ± 5.7% in S-WL (P<.001). In P-WL, a fast initial pouch emptying and exponential emptying curve was observed, compared with a slower initial emptying and more linear curve in S-WL. Faster emptying in P-WL was also shown by a larger IC meal (42 ± 18% versus 4.0 ± 3.3%,), IC 15 (76 ± 15% versus 35 ± 22%), and IC 30 (85 ± 12% versus 54 ± 25%), and a greater maximal pouch emptying rate (17 ± 4.7 versus 5.6 ± 3.4%/min) compared with S-WL (P<.05). A linear correlation was found between total weight loss and maximal pouch emptying rate (Pearson R = .82, P = .004). Pouch emptying for solid food was faster in patients with the least weight loss compared with patients with the most weight loss after RYGB. If pouch emptying is an important mechanism in weight loss, altering the pouch outlet may improve poor weight loss management. Copyright © 2017 American Society for Bariatric Surgery.

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.

To examine the effects of three commonly used intra-articular depot corticosteroid preparations tested in a rat air pouch model and their effect against monosodium urate (MSU) crystal-induced inflammation. Rheumatologists use intra-articular corticosteroid preparations to relieve pain and inflammation of acute monoarthritis without really knowing their effects on the synovial fluid and membrane or the differences between distinct preparations. This work compares the effect of three commonly used corticosteroid preparations in vivo, showing that they behave differently. A subcutaneous air pouch was formed in male Sprague-Dawley rats. A first group of 6-day-old air pouches were injected with 10 ml of 6 mg/ml normal saline solution, 6 mg/ml betamethasone containing both depot betamethasone acetate and soluble betamethasone phosphate (Celestone) in 9 ml of normal saline solution, 20 mg/ml of prednisolone tebutate (Hydeltra) in 9 ml of normal saline solution or 20 mg/ml of triamcinolone hexacetonide (Aristospan) in 9 ml of normal saline solution. A second group (group 2) of air pouches were injected with 15 mg of synthetic MSU crystals and 24 h later they were reinjected with 1 ml of the same three corticosteroid suspensions. For each condition four rats were killed at 6, 24, 48 h and 7 days. Pouch fluid and tissue were analysed. In the first 6 h after normal saline solution or corticosteroid injection into the air pouch there were mildly increased leucocyte counts in the air pouch fluid. Betamethasone-injected pouches showed no cells in the fluid after 6 h and no crystals after 24 h, triamcinolone-injected pouches still showed rare cells at 7 days. Both triamcinolone and prednisolone crystals persisted in higher numbers and lasted longer in the fluid than did betamethasone (P<0.05). In group 2 MSU crystal phagocytosis in the fluid was decreased in the betamethasone- (P<0.01), prednisolone- (P<0.003) and triamcinolone- (P<0.006) injected pouches when compared with the

Transmesenteric hernias are extremely rare. A strangulated hernia through a mesenteric opening is a rare operative finding. Preoperative diagnosis still is difficult in spite of the imaging techniques currently available. The authors describe two cases of paediatric patients presenting with bowel obstruction resulting from a congenital mesenteric hernia. The first patient had a 3-cm wide congenital defect in the ileal mesentery through which the sigmoid colon had herniated. The second patient is a newborn infant who presented with symptoms and radiographic evidence of neonatal occlusion. At surgical exploration, a long segment of the small bowel had herniated in a defect in the ileal mesentery. A brief review of epidemiology and anatomy of transmesenteric hernias is included, along with a discussion of the difficulties in diagnosis and treatment of this condition.

Development and evaluation of a reflective solar disinfection pouch for treatment of drinking water.

A second-generation solar disinfection (SODIS) system (pouch) was constructed from food-grade, commercially available packaging materials selected to fully transmit and amplify the antimicrobial properties of sunlight. Depending upon the season, water source, and challenge organism, culturable bacteria were reduced between 3.5 and 5.5 log cycles. The system was also capable of reducing the background presumptive coliform population in nonsterile river water below the level of detection. Similar experiments conducted with a model virus, the F-specific RNA bacteriophage MS2, indicated that the pouch was slightly less efficient, reducing viable plaques by 3.5 log units in comparison to a 5.0 log reduction of enterotoxigenic Escherichia coli O18:H11 within the same time period. These results suggest that water of poor microbiological quality can be improved by using a freely available resource (sunlight) and a specifically designed plastic pouch constructed of food-grade packaging materials.

Harvey, B.V.; Squier, C.A.; Hall, B.K.

This study examined the effects of chlorhexidine (CHD) on the clinical appearance, morphology, and in vitro permeability of hamster cheek pouch mucosa. The cheek pouches were treated daily for 3 weeks with topical applications of saline, 0.2% CHD, or 2.0% CHD. Treatment with 2.0% CHD resulted in the formation of discrete white lesions in every animal in the group, whereas no changes were identified in any animal treated with 0.2% CHD or saline. Upon microscopic examination it was determined that treatment with 2.0% CHD resulted in a statistically significant increase in epithelial thickness, when compared to the other groups, andmore » the lesions were found to consist of hyperplastic areas of epithelium with associated inflammatory cell accumulations. Daily treatments with 2.0% CHD, 0.2% CHD or saline had no effect on the very low permeability of cheek pouch mucosa to /sup 14/C-CHD. However, treatment with 2.0% CHD resulted in decreased permeability to /sup 3/H/sub 2/O when compared to the other groups. Treatment with 2.0% CHD also resulted in a thickened permeability barrier, as determined using a tracer, horseradish peroxidase. It is concluded that topical applications of 0.2% T CHD have no detectable effect on cheek-pouch mucosa while applications of 2.0% CHD result in hyperplasia and a decrease in mucosal permeability. Results suggest that CHD should be used with caution clinically and at a concentration of 0.2% or less.« less

The authors report a case of congenital chloride diarrhea with molecular confirmation of diagnosis. A 10-mo-old boy presented with failure to thrive, voluminous diarrhea, dehydration, hyponatremia, hypokalemia, metabolic alkalosis and history of maternal polyhydramnios. The diagnosis of congenital chloride diarrhea was based on high fecal and low urinary chloride excretion, in addition to biochemical abnormalities. Genetic testing revealed a novel homozygous mutation in exon 4 of the SLC26A3 gene that encodes the protein regulating chloride bicarbonate absorption in distal ileum and colon. Therapy with oral fluids and electrolytes led to decrease in stool frequency and improvement in growth parameters.

Until recently, surgeons have been posed with a dilemma---whether or not they should preserve the terminal end of the distal rectal pouch and the fistula region in anorectal malformations (ARMs). A detailed histological study of this region was conducted to establish a consensus for preserving or excising this region for reconstruction of ARMs. Histopathological examination using haematoxylin and eosin-stained sections of the terminal portion of the distal rectal pouch and proximal portion of the rectourogenital or rectoperineal connection was performed in 60 cases of high, intermediate and low ARMs. Distorted internal sphincter was present in 93.3% of high, 90% of intermediate and 100% of low ARMs. The proximal fistula region was lined by transitional epithelium in 50% of cases, and anal glands were present in 83.3% and anal crypts in 68.3% of cases. The rectal pouch in the region of the internal sphincter and fistula was aganglionic in all cases. This study shows that the terminal end of the distal rectal pouch and proximal fistula region possess distorted anal features with aganglionosis, and contradicts the recommendation that this region should be reconstructed in patients with malformations.

The aim of this study was to evaluate the quality of life and functional emptying of J-pouch versus Roux-en-Y reconstruction after total gastrectomy for malignancy. This study was designed as a prospective, nonblinded, randomized, parallel clinical trial (Trial Number: MN Ostrava, 200604). With informed consent, patients undergoing gastrectomy for malignancy were randomized to J-pouch or Roux-en-Y reconstruction. The time taken for a test semisolid meal labeled with 99m Tc-sulfur colloid to exit the reconstructed parts was measured by dynamic scintigraphy 1 year after resection. Quality of life was measured using the Eypasch questionnaire at the same time as functional emptying assessment. This trial was investigator-initiated. In all, 72 patients were included into the study. The time taken for the test meal to exit the postgastrectomy reconstruction was 16.5±10.0 minutes (mean ± standard deviation) in the Roux-en-Y group and 89.4±37.8 minutes in the "J-pouch" group; the difference was statistically significant ( P <0.001). Emptying of the J-pouch appeared to be a linear decreasing function compared to the exponential pattern seen in the Roux-en-Y group. The quality of life measurement showed scores of 106±18.8 points (mean ± standard deviation) in the Roux-en-Y group compared to 122±22.5 points in the J-pouch group; the difference was statistically significant ( P =0.0016). There were no important adverse events. After total gastrectomy, a J-pouch reconstruction empties more slowly and is associated with higher quality of life compared to Roux-en-Y reconstruction. Whether these two observations have a direct causative link remains unanswered.

A fourth branchial pouch sinus is a rare congenital anomaly, which in a 13-year-old girl presented clinically as recurrent deep cervical abscesses. The location of the majority of these anomalies is the left side of the neck (90%). Radiological and endoscopic investigations verified the diagnosis. The internal orifice located at the apex of the pyriform sinus could facilitate contamination by infectious pharyngeal secretions and lead to abscess recurrence. Traditionally, the recommended treatment is radical surgery. It can, however, be technically difficult to excise the whole fistula tract. In this patient we used a non-invasive treatment modality; chemocauterization with 40% trichloroacetic acid (TCA). After three treatments the fistula was closed. To date (month no. 15) there has been no abscess recurrence. TCA chemocauterization seems to be a safe first-line treatment for patients with pyriform sinus fistulas.

The development of a left ventricular (LV) apical pouch in patients with apical hypertrophic cardiomyopathy (aHCM) has been thought to be the transition point that can become an apical aneurysm, which is linked to higher risk of adverse events. In our study, we sought to compare the ability of transthoracic echocardiography (echo) and cardiac magnetic resonance imaging (cMRI) to accurately identify the presence of an apical pouch or aneurysm in patients with aHCM. We retrospectively reviewed the charts of all consecutive patients that had features of aHCM on imaging. Data from cMRI and echo examinations were abstracted, and the ability of these diagnostic modalities to identify the presence of a LV apical pouch and aneurysm was analyzed. Of 31 patients with aHCM, 17 (54.8%) had an apical pouch and 2 were found to have apical aneurysm (6.5%) on cMRI. Echo with and without perflutren contrast was able to accurately identify both aneurysms, but only 47.1% (8/17) of apical pouches seen by cMRI. Two patients had apical thrombus that was identified by cMRI, but not by echo. Our findings indicate that cMRI is superior to echo in identifying apical pouches in patients with aHCM. Our results also suggest that in patients undergoing echo, the use of perflutren contrast for LV opacification increases the diagnostic yield. Further study is necessary to delineate whether earlier identification of an apical pouch will be of clinical benefit for patients with aHCM by altering clinical management and avoiding adverse cardiovascular events. © 2015, Wiley Periodicals, Inc.

Ulcerative colitis (UC) patients requiring colectomy often have a staged ileal pouch anal anastomosis (IPAA). There are no prospective data comparing timing of pouch creation. We aimed to compare 30-day adverse event rates for pouch creation at the time of colectomy (PTC) with delayed pouch creation (DPC). Using prospectively collected data from 2011-2015 through the National Surgical Quality Improvement Program, we conducted a cohort study including subjects aged ≥18 years with a postoperative diagnosis of UC. We assessed 30-day postoperative rates of unplanned readmissions, reoperations, and major and minor adverse events (AEs), comparing the stage of the surgery where the pouch creation took place. Using a modified Poisson regression model, we estimated risk ratios (RRs) with 95% confidence intervals (CIs) adjusting for age, sex, race, body mass index, smoking status, diabetes, albumin, and comorbidities. Of 2390 IPAA procedures, 1571 were PTC and 819 were DPC. In the PTC group, 51% were on chronic immunosuppression preoperatively, compared with 15% in the DPC group (P < 0.01). After controlling for confounders, patients who had DPC were significantly less likely to have unplanned reoperations (RR, 0.42; 95% CI, 0.24-0.75), major AEs (RR, 0.72; 95% CI, 0.52-0.99), and minor AEs (RR, 0.48; 95% CI, 0.32-0.73) than PTC. Patients undergoing delayed pouch creation were at lower risk for unplanned reoperations and major and minor adverse events compared with patients undergoing pouch creation at the time of colectomy. 10.1093/ibd/izy082_video1izy082.video15776112442001.

The Quechua manta pouch: a caretaking practice for buffering the Peruvian infant against the multiple stressors of high altitude.

The manta pouch--a caretaking practice of tightly swaddling and enclosing the infant in a set of cloths and blankets--and other caretaking practices are described for high-altitude resident (> 4,000 m) Quechua mother-infant pairs (N = 14). The manta pouch modifies the microenvironment inside the pouch so that, compared to the ambient environment, the temperature is higher and more stable, the humidity is higher, the partial pressure of O2 is lower, and stimulation levels are reduced. As the infant gets older, the characteristics of the pouch are modified such that the infant is increasingly exposed to ambient conditions. These caretaking practices may benefit the infant by buffering the infant from the multiple ecological stressors of high altitude, but they may also incur costs by exposing the infant to additional microenvironmental stressors (e.g., higher CO2 levels) and by reducing stimulation and limiting infant movement.

Model comparison for Escherichia coli growth in pouched food.

We recently studied the growth characteristics of Escherichia coli cells in pouched mashed potatoes (Fujikawa et al., J. Food Hyg. Soc. Japan, 47, 95-98 (2006)). Using those experimental data, in the present study, we compared a logistic model newly developed by us with the modified Gompertz and the Baranyi models, which are used as growth models worldwide. Bacterial growth curves at constant temperatures in the range of 12 to 34 degrees C were successfully described with the new logistic model, as well as with the other models. The Baranyi gave the least error in cell number and our model gave the least error in the rate constant and the lag period. For dynamic temperature, our model successfully predicted the bacterial growth, whereas the Baranyi model considerably overestimated it. Also, there was a discrepancy between the growth curves described with the differential equations of the Baranyi model and those obtained with DMfit, a software program for Baranyi model fitting. These results indicate that the new logistic model can be used to predict bacterial growth in pouched food.

To report our experience with different approaches for management of pouch stones in children with ileal-based urinary reservoir. Charts of children who underwent ileal-based urinary reservoirs between 2000 and 2009 were retrospectively reviewed. Patients who were diagnosed with reservoir calculi were identified; medical records were reviewed for patients' demographics, diversion details, stone criteria, mode of treatment, perioperative complications, and recurrence rate. We identified 26 children with pouch stones after urinary diversion. There were 11 boys (42%) and 15 girls (58%). Mean age was 11 years (range, 4-16 years). Mean time for diagnosis was 42 months (24-120 months). Pouch stones were asymptomatic in 10 patients (38%). Fifteen cases were postbladder augmentation and 11 cases postcontinent cutaneous diversion. The mean stone size was 4 cm (range, 1-10 cm), and mean Hounsfield Unit was 585 (205-1090). Seventeen children (65%) had positive urine culture result, whereas 9 children were sterile. Seven children (27%) required open poucholithotomy, whereas 19 patients (73%) were managed endoscopically. Percutaneous approach was done in 5 children, whereas urethral access was used in 7 children. Mechanical extraction was performed in 12 cases, and stone disintegration was required in 7 cases. Eight children developed stone recurrence. Mean time for recurrence was 11 months (range, 3-19 months). Six children were after endoscopic disintegration, and all required redo endoscopic extraction. Stone analysis was available in 15 patients (struvite stones in 10 cases and calcium phosphate in 5 cases). Pouch stones are established long-term complication of urinary diversion. Open and endoscopic approaches are valid treatment strategies. Copyright © 2015 Elsevier Inc. All rights reserved.

Congenital diaphragmatic disease is a quite common condition that usually occurs in the neonatal period, and the diagnosis of congenital diaphragmatic disease in adulthood is rare. A 64-years-old Caucasian woman was admitted in emergency at our Department, due to a bowel obstruction and dyspnea. A CT-scan showed a diaphragmatic herniation in the left area, with malposition of dilated transverse and descending colon in the chest. An emergency laparatomy was performed, showing a toxic megacolon, in the absence of a true diaphragmatic hernia, and a left diaphragm and left liver hypoplasia. An intraoperative bronchoscopy revealed concomitant hypoplasia of the left lung. A subtotal colectomy with ileo-rectal anastomosis was performed. The postoperative course was uneventful. Histological examination demonstrated hyperplasia of the muscularis mucosae of the colon and cytoplasmic vacuolization of the Auerbach plexus ganglia. The karyotype genetic analysis excluded concomitant microdeletion or duplication syndromes. To our knowledge, this seems to be the first reported case of toxic megacolon in a patient with congenital hypoplasia of the left bronchial-lung system, of the left liver, and of the left diaphragm. The correct development of the diaphragm is essential for the neighboring organs. The observed clinical pattern could be related to a partial modification of neural crest cell detachment or migration, which could be responsible for bowel and diaphragm defects, even though it was not included in typical neural crest cell syndromes. Further researches should be performed in order to define the sporadic or syndromic source of these multiorgan defects. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

The choice of the experimental aneurysm model is essential for valid embolization-device evaluations. So far, the use of the rabbit venous pouch arterial bifurcation aneurysm model has been limited by demanding microsurgery, low aneurysm patency rates, and high mortality. This study aimed to facilitate microsurgery and to reduce mortality by optimized peri-/postoperative management. Aneurysms were created in 16 New Zealand white rabbits under general intravenous anesthesia. Using modified microsurgical techniques, we sutured a jugular vein pouch into a bifurcation created between both CCAs. Aggressive anticoagulation (intraoperative intravenous: 1000-IU heparin, 10-mg acetylsalicylic acid/kg; postoperative subcutaneous: 14 days, 250-IU/kg /day heparin) and prolonged postoperative anesthesia (fentanyl patches: 12.5 μg/h for 72 hours) were applied. Angiographic characteristics of created experimental aneurysms were assessed. The reduced number of interrupted sutures and aggressive anticoagulation caused no intra-/postoperative bleeding, resulting in 0% mortality. Four weeks postoperation, angiography showed patency in 14 of 16 aneurysms (87.5%) and Ohshima type B bifurcation geometry. Mean values of parent-artery diameters (2.3 mm), aneurysm lengths (7.9 mm), and neck widths (4.1 mm) resulted in a mean 1.9 aspect ratio. Compared with historical controls, the use of modified microsurgical techniques, aggressive anticoagulation, and anesthesia resulted in higher aneurysm patency rates and lower mortality rates in the venous pouch arterial bifurcation aneurysm model. Gross morphologic features of these aneurysms were similar to those of most human intracranial aneurysms.

Inducing angiogenesis is one hallmark of cancer. Tumor induced neovasculature is often characterized as leaky, tortuous and chaotic, unlike a highly organized normal vasculature. Additionally, in the course of carcinogenesis, angiogenesis precedes a visible lesion. Tumor cannot grow beyond 1-2 mm in diameter without inducing angiogenesis. Therefore, capturing the event of angiogenesis may aid early detection of pre-cancer -important for better treatment prognoses in regions that lack the resources to manage invasive cancer. In this study, we imaged the neovascularization in vivo in a spontaneous hamster cheek pouch carcinogen model using a, non-invasive, label-free, high resolution, reflected-light spectral darkfield microscope. Hamsters' cheek pouches were painted with 7,12-Dimethylbenz[a]anthracene (DMBA) to induce pre-cancerous to cancerous changes, or mineral oil as control. High resolution spectral darkfield images were obtained over the course of pre-cancer development and in control cheek pouches. The vasculature was segmented with a multi-scale Gabor filter with an 85% accuracy compared with manually traced masks. Highly tortuous vasculature was observed only in the DMBA treated cheek pouches as early as 6 weeks of treatment. In addition, the highly tortuous vessels could be identified before a visible lesion occurred later during the treatment. The vessel patterns as determined by the tortuosity index were significantly different from that of the control cheek pouch. This preliminary study suggests that high-resolution darkfield microscopy is promising tool for pre-cancer and early cancer detection in low resource settings.

Pouchitis is the most frequent complication after ileal pouch-anal anastomosis for refractory ulcerative colitis. A non-standardized preventative treatment exists. Sulfasalazine has proved effective in acute pouchitis therapy. The aim of this study was to retrospectively evaluate the effect of sulfasalazine in primary prophylaxis of pouchitis after proctocolectomy with ileal pouch-anal anastomosis. Data files of patients who underwent total proctocolectomy with ileal pouch-anal anastomosis for refractory ulcerative colitis and/or dysplasia from January 2007 to December 2014, with a follow-up until August 2015, were analyzed. After closure of loop ileostomy, on a voluntary basis, patients received a primary prophylaxis of pouchitis with sulfasalazine (2000 mg per day) continually until acute pouchitis flare and/or drop out due to side effects. Follow-up data were available for 51 of the 55 surgical patients. Median follow-up time was 68 months (range 10-104). Thirty postoperative complications occurred in 25 patients. 45% of patients developed pouchitis. Sulfasalazine prophylaxis was administered in 39.2% of patients; 15% of the these developed pouchitis versus 64.5% (20/31) of the non-sulfasalazine patients (p < 0.001). Pouchitis-free survival curves were 90.55 months in sulfasalazine patients and 44.46 in non-sulfasalazine patients (log-rank test p = 0.001, Breslow p = 0.001). Sulfasalazine may be potentially administered in pouchitis prophylaxis after proctocolectomy with ileal pouch-anal anastomosis, but large prospectively controlled trials are needed.

The literature on gastric carcinoma after gastroplasty is reviewed.

Adenocarcinoma in the anal transitional zone after ileal pouch for ulcerative colitis: report of a case.

PubMed

Bell, Stephen W; Parry, B; Neill, M

2003-08-01

This article reports the seventh known case of adenocarcinoma arising in or adjacent to an ileal pouch after proctocolectomy for ulcerative colitis. It is the second reported case of adenocarcinoma in the anal transitional zone in this setting. A literature review is presented of the six previous cases published, and on the wider subject of how to best manage the anal transitional zone. It is concluded that this is a rare, but catastrophic, event with a potentially poor prognosis and can occur late (more than a decade) after the original surgery. All ileal pouches performed for ulcerative colitis should be followed for extended periods. The development of dysplasia necessitates close follow-up, including regular biopsies, and local excision and pouch advancement can manage persistent dysplasia. When operating for dysplasia or cancer, biopsies of the anal transitional zone should be performed or consideration given to mandatory mucosectomy.

Branchial pouch-derived anomalies may arise from remnants of the first, second, or third/fourth branchial arches. Branchial pouch-related structures are found within the thyroid gland in the form of solid cell rests, epithelial lined cyst with or without an associated lymphoid component, thymic and/or parathyroid tissue, and less commonly in the form of heterotopic cartilage. We present a rare case of left solid thyroid swelling nearby two cervical nodules in a seven-year-old female with a clinical diagnosis suggestive of malignant thyroid tumor with metastasis to the cervical lymph nodes. Histopathological examination revealed that it was compatible with third/fourth branchial pouch-derived anomaly composed of mature cartilage and thymic and parathyroid tissues for clinical and radiological correlations.

An interlaboratory study was carried out to determine the feasibility and reliability of a method using the hamster cheek pouch as a model for assessing the potential irritative properties of substances intended to be applied to the lips or other mucous membranes. The test substances were applied once daily to both pouches for 14 consecutive days. Local and general tolerances were appraised throughout the study. At the end of the study, histologic examination of the pouches and the main organs was performed. Results of the feasibility study, conducted on various types of commercial products, indicated that this model is suitable for preparations of various consistence and composition. Results of the reliability study, carried out on gel-type preparations containing various concentrations of a known irritant, sodium lauryl sulfate, indicated that the method elicits a dose-dependent reaction for this compound. This hamster cheek pouch method was reproducible for the various parameters under consideration: local tolerance, general tolerance, histologic examination. For all products, results were in good agreement among the various laboratories participating in the study. The French regulatory authorities of the Fraud Repression Department have accepted it as an official method for the evaluation of the potential irritative properties of cosmetics and hygiene products intended to be applied to the lips or other mucous membranes.

Poor pouch function after restorative proctocolectomy for ulcerative colitis is a considerable problem. Pouchitis and functional disorders are the most common reasons. Probiotics seem to have a beneficial effect in pouchitis but have not been assessed in functional pouch disorders. The aim was to analyse the effects of probiotics in patients with poor pouch function. Thirty-three patients were randomized to probiotics (Lactobacillus plantarum 299 and Bifidobacterium infantis Cure 21) or placebo in a double blinded, 1:1 fashion. The treatment effect was assessed by the pouch functional score (PFS; 0-15, 15 worst), pouchitis disease activity index (PDAI; 0-18, 18 worst), and levels of four faecal biomarkers of inflammation (calprotectin, lactoferrin, myeloperoxidase [MPO] and eosinophilic cationic protein [ECP]). Thirty-two patients were included (probiotics = 17, placebo = 16). There was no difference in change in the PFS from before to after treatment between the groups (median difference: -1.00, 95% C.I. -3.00 to 0.00, p = 0.119). Furthermore, probiotics had no effect on PDAI (median difference: 0.00, 95% C.I. 0.00-1.00, p = 0.786), or on faecal biomarkers. Significant correlations were observed between PDAI and each of the faecal biomarkers at study start. There were no correlations between PFS or PDAI symptom subscore and the biomarkers. PDAI endoscopic and histologic subscores correlated significantly to each of the biomarkers. The hypothesis that probiotics improves pouch-related dysfunction was not confirmed. Faecal biomarkers could play a future role in the management of pouch patients.

Mast cell (MC) activation in the hamster cheek pouch cancerization model is associated with the increase in tumor cell proliferation, mediated in turn by tryptase, a protease released from mast cell granules after activation. Tryptase induces tumor cell proliferation through the activation of PAR-2 (protease activated receptor-2) on the plasma membrane of carcinoma cells. The therapeutic success of boron neutron capture therapy mediated by boronophenylalanine (BPA-BNCT) in tumor control in the hamster cheek pouch oral cancer model has been previously reported by our laboratory. Early effects of BPA-BNCT on tumors of the hamster cheek pouch include a reduction in DNA-synthesis with the concomitant decrease in the proliferation of malignant cells. The aim of the present study was to investigate the early histological changes in mast cells after BPA-BNCT in tumors and premalignant tissue of the hamster cheek pouch. Tumor-bearing pouches were treated with BPA-BNCT or beam only (neutron irradiation without prior administration of the boron compound) and sacrificed 1day after treatment. The samples were fixed in Carnoy fixative and stained with alcian blue-safranin to identify all the populations of mast cells. Total, active and inactive mast cells (MC) were counted in the connective tissue and the adventitious tissue underlying the pouch wall and at the base of the tumors in pouches treated with BPA-BNCT, in keeping with a previously described technique. BPA-BNCT induced a marked reduction in the total number of mast cells in the pouch (p<0.05). This reduction in the total number of mast cells was due to a reduction in mast cells at the base of the tumor (p<0.005) and it occurred at the expense of the active mast cells (p<0.05). A slight reduction that did not reach statistical significance also occurred in the amount of mast cells in the pouch wall (that corresponds to the premalignant tissue in tumor-bearing pouches), and in the adventitious tissue. In this case the

Rheumatoid arthritis (RA) is a systemic inflammatory disease with cardiovascular complications as the leading cause of morbidity. Carvedilol is an adrenergic antagonist which has been safely used in treatment of several cardiovascular disorders. Given that carvedilol has powerful antioxidant/anti-inflammatory properties, we aimed to investigate its protective potential against arthritis that may add further benefits for its clinical usefulness especially in RA patients with concomitant cardiovascular disorders. Two models were studied in the same rat; adjuvant arthritis and subcutaneous air pouch edema. Carvedilol (10 mg/kg/day p.o. for 21 days) effectively suppressed inflammation in both models with comparable efficacy to the standardmore » anti-inflammatory diclofenac (5 mg/kg/day p.o.). Notably, carvedilol inhibited paw edema and abrogated the leukocyte invasion to air pouch exudates. The latter observation was confirmed by the histopathological assessment of the pouch lining that revealed mitigation of immuno-inflammatory cell influx. Carvedilol reduced/normalized oxidative stress markers (lipid peroxides, nitric oxide and protein thiols) and lowered the release of inflammatory cytokines (TNF-α and IL-6), and eicosanoids (PGE{sub 2} and LTB{sub 4}) in sera and exudates of arthritic rats. Interestingly, carvedilol, per se, didn't present any effect on assessed biochemical parameters in normal rats. Together, the current study highlights evidences for the promising anti-arthritic effects of carvedilol that could be mediated through attenuation of leukocyte migration, alleviation of oxidative stress and suppression of proinflammatory cytokines and eicosanoids. - Highlights: ► Carvedilol possesses promising anti-arthritic properties. ► It markedly suppressed inflammation in adjuvant arthritis and air pouch edema. ► It abrogated the leukocyte invasion to air pouch exudates and linings. ► It reduced/normalized oxidative stress markers in sera and exudates

AIM: To determine the effect of three digestive tract reconstruction procedures on pouch function, after radical surgery undertaken because of gastric cancer, as assessed by radionuclide dynamic imaging. METHODS: As a measure of the reservoir function, with a designed diet containing technetium-99m (99mTc), the emptying time of the gastric substitute was evaluated using a 99mTc-labeled solid test meal. Immediately after the meal, the patient was placed in front of a γ camera in a supine position and the radioactivity was measured over the whole abdomen every minute. A frame image was obtained. The emptying sequences were recorded by the microprocessor and then stored on a computer disk. According to a computer processing system, the half-emptying actual curve and the fitting curve of food containing isotope in the detected region were depicted, and the half-emptying actual curves of the three reconstruction procedures were directly compared. RESULTS: Of the three reconstruction procedures, the half-emptying time of food containing isotope in the Dual Braun type esophagojejunal anastomosis procedure (51.86 ± 6.43 min) was far closer to normal, significantly better than that of the proximal gastrectomy orthotopic reconstruction (30.07 ± 15.77 min, P = 0.002) and P type esophagojejunal anastomosis (27.88 ± 6.07 min, P = 0.001) methods. The half-emptying actual curve and fitting curves for the Dual Braun type esophagojejunal anastomosis were fairly similar while those of the proximal gastrectomy orthotopic reconstruction and P type esophagojejunal anastomosis were obviously separated, which indicated bad food conservation in the reconstructed pouches. CONCLUSION: Dual Braun type esophagojejunal anastomosis is the most useful of the three procedures for improving food accommodation in patients with a pouch and can retard evacuation of solid food from the reconstructed pouch.

Hospital records reviewed over a 12-year period determined that 6 horses had been presented for guttural pouch mycosis. All had a history of epistaxis and several had accompanying neurologic signs, including dysphagia. Initially, conformation of the disease was obtained by radiographic and endoscopic examinations. Surgical treatment was directed at controlling and preventing additional hemorrhage by occluding the arterial source of the hemorrhage. Direct treatment of the mycotic plaque present within the guttural pouch was conducted using transendoscopic technique to direct irradiation from the Nd:YAG laser. The protocol described for the laser application was successful in resolving the lesions and was less complicated and stressful than previously reported topically applied chemical protocols.

The antagonists of 5HT(3) receptors have shown impressive efficacy in rheumatoid arthritis, osteoarthritis or fibromyalgia. The mechanistic relationships between 5HT(3) receptors, angiogenesis and sequence of cytokine expression, and leukocyte recruitment during inflammation are not clear. We evaluate the effects of granisetron on inflammatory parameters and angiogenesis in rat air-pouch model. Male Wistar rats were anesthetized, and then 20 ml and 10 ml of sterile air were injected subcutaneously in the back on day 0 and day 3, respectively. On day 6, inflammation was induced by injection of 1 ml of carrageenan 1% into pouches. After 6 and 72 h, the rats were sacrificed; pouch fluid was collected in order to determine exudate volume, the number of accumulated cells and TNFalpha/PGE(2) concentration. Pouches were dissected out and weighed. Angiogenesis of granulomatous tissue was assayed using a hemoglobin kit. Leukocyte accumulation was dose-dependently inhibited by granisetron both at 6 and 72 h after induction of inflammation. All doses of granisetron decreased hemoglobin level in the whole granulation tissue in a bell-shaped manner. Vascular network formation was also inhibited by granisetron. Granisetron increased PGE(2) level at a lower dose (50 microg/pouch) but higher doses (100 and 200 microg/pouch) inhibited the release. At the same time, TNFalpha production was decreased by the lower dose and increased by higher doses of granisetron in a reciprocal fashion. Anti-inflammatory activities of 5HT(3) receptor antagonist, granisetron probably are mediated through modulation of TNFalpha/PGE(2) production and leukocyte infiltration. (c) 2010 Elsevier B.V.

Transverse colon volvulus is an uncommon cause of bowel obstruction in general. Predisposing factors are mental retardation, dysmotility disorders, chronic constipation and congenital megacolon. We presented transverse colon volvulus in a 16-year-old boy with cerebral palsy. Chronic constipation in neurologicaly impaired patient was a risk factor predisposing to volvulus. The patient was admitted to the hospital with enormous abdominal distension and acute respiratory insufficiency. A boy was emergently taken to the operating room for exploratory laparotomy. During the surgery, a 360º clockwise volvulus of the transverse colon was found. After reduction of volvulus, an enormous transverse colon was resected and colostomy was formed. In the postoperative period, despite the good functioning of stoma and intraabdominal normotension, numerous and long lasting respiratory problems developed. The patient was discharged from our institution after 8 months. Though very rare in pediatric group, the possibility of a transverse colon volvulus must be considered in the differential diagnosis of acute large bowel obstruction.

Objective We tested the hypothesis that differential stimulation of nitric oxide (NO) production can be induced in pre- and postcapillary segments of the microcirculation in the hamster cheek pouch. Methods We applied acetylcholine (ACh) or platelet-activating factor (PAF) topically and measured perivascular NO concentration ([NO]) with NO-sensitive microelectrodes in arterioles and venules of the hamster cheek pouch. We also measured NO in cultured coronary endothelial cells (CVEC) after ACh or PAF. Results ACh increased periarteriolar [NO] significantly in a dose-dependent manner. ACh at 1 μM increased [NO] from 438.1±43.4 nM at baseline to 647.9±66.3 nM, while 10 μM ACh increased [NO] from baseline to 1035.0±59.2 nM (P < 0.05). Neither 1 μM nor 10 μM ACh changed perivenular [NO] in the hamster cheek pouch. PAF, at 100 nM, increased perivenular [NO] from 326.6±50.8 nM to 622.8±41.5 nM. Importantly, 100 nM PAF did not increase periarteriolar [NO]. PAF increased [NO] from 3.6 ± 2.1 to 455.5 ± 19.9 in CVEC, while ACh had no effect. Conclusions We conclude that NO production can be stimulated in a differential manner in preand postcapillary segments in the hamster cheek pouch. ACh selectively stimulates the production of NO only in arterioles, while PAF stimulates the production of NO only in venules. PMID:19235626

More data are warranted on the economic impact of different treatment strategies in ulcerative colitis (UC) patients. We compared the costs and quality of life of UC patients with a pouch reconstruction, an ileostomy or anti-tumour necrosis factor α (TNFα) therapy. UC patients filled out 3-monthly questionnaires for 2 years. Differences in 3-monthly healthcare costs, productivity costs and patient costs were tested using mixed model analysis. Quality of life was assessed employing the ) and the inflammatory bowel disease questionnaire (IBDQ). Out of 915 UC patients, 81 (9%) had a pouch and 48 (5%) an ileostomy, and 34 (4%) were on anti-TNFα therapy. Anti-TNFα-treated patients reported high UC related-healthcare costs per 3 months (€5350). Medication use accounted for 92% of healthcare costs. UC-attributable healthcare costs were 3-fold higher in ileostomy patients compared with pouch patients (€1581 versus €407; p < 0.01). Main cost drivers in ileostomy patients were healthcare costs and ileostomy supplies (2 and 23% of healthcare costs, respectively). In pouch patients, the main cost driver was hospitalization, accounting for 50% of healthcare costs. Productivity loss did not differ between pouch and ileostomy patients (€483 versus €377; p < 0.23), but was significantly higher in anti-TNFα-treated patients (€1085). No difference was found in IBDQ scores, but pouch patients were found to have higher quality-adjusted life years than ileostomy patients and anti-TNFα-treated patients (0.90 [interquartile range 0.78-1.00] versus 0.84 [0.78-1.00] and 0.84 [0.69-1.00], respectively; p < 0.01). Patients receiving anti-TNFα therapy reported the highest healthcare cost, in which medication use was the major cost driver. Ileostomy patients were three times more expensive than pouch patients due to frequent hospitalization and ileostomy supplies. Copyright © 2015 European Crohn’s and Colitis Organisation (ECCO).

Budesonide has been studied in patients with primary sclerosing cholangitis (PSC). This study was designed to evaluate the efficacy of oral budesonide on liver function tests in patients with PSC and pouchitis associated with ileal pouch-anal anastomosis (IPAA). The study group consisted of 18 pouch patients with underlying ulcerative colitis (UC) and PSC who were treated with 9 mg daily of budesonide for their underlying pre-pouch ileitis and pouchitis for 1-3 months followed by 3-6 mg maintenance for another 9 months. Demographic and clinical variables were analyzed. The mean age was 39.4±12.4 years (range, 21-59 years). There was no significant change in aspartate aminotransferase (AST) [median (interquartile range) (IQR) 32 (25, 43.8) vs. 35.5 (25.5, 53), p=0.35], alanine aminotransferase (ALT) [37.5 (25.5, 49.5) vs. 40 (30, 84.3), p=0.29], alkaline phosphatase [142.5 (98.5, 264.5) vs. 126 (94.3, 189.5), p=0.35], serum bilirubin [0.7 (0.4, 1.3) vs., 0.6 (0.4, 1.6), p=0.13] or albumin levels [4.3 (3.9, 4.4) vs. 4.2 (3.8, 4.4), p=0.22] at the end of the treatment period (1 year). The revised Mayo Risk Score did not change significantly and three patients required evaluation for liver transplantation during treatment. There was a significant improvement in the endoscopy subscores in the afferent limb and pouch after a year of budesonide treatment (p=0.001). Oral budesonide appears to have no impact on liver function tests in pouch patients with PSC. However it significantly improved afferent limb and pouch inflammation in IPAA patients.

Wang, W.

1993-01-01

Paper substrate, especially circular filter paper placed inside a Petri dish, has long been used for the plant seed toxicity test (PSTT). Although this method is simple and inexpensive, recent evidence indicates that it gives results that are significantly different from those obtained using a method that does not involve paper, especially when testing metal cations. The study compared PSTT using three methods: filter paper, Growth Pouch-TM, and seed tray. The Growth Pouch-TM is a commercially available device. The seed tray is a newly designed plastic receptacle placed inside a Petri dish. The results of the Growth Pouch-TM method showed no toxic effects on rice for Ag up to 40 mg L-1 and Cd up to 20 mg L-1. Using the seed tray method, IC50 (50% inhibitory effect concentration) values were 0.55 and 1.4 mg L-1 for Ag and Cd, respectively. Although results of filter paper and seed tray methods were nearly identical for NaF, Cr(VI), and phenol, the toxicities of cations Ag and Cd were reduced by using the filter paper method; IC50 values were 22 and 18 mg L-1, respectively. The results clearly indicate that paper substrate is not advisable for PSTT.

Our research is exploiting the marsupial as a model to understand the signals required for lung development. Marsupials have a unique reproductive strategy, the mother gives birth to altricial neonate with an immature lung and the changes in milk composition during lactation in marsupials appears to provide bioactives that can regulate diverse aspects of lung development, including branching morphogenesis, cell proliferation and cell differentiation. These effects are seen with milk collected between 25 and 100days postpartum. To better understand the temporal effects of milk composition on postnatal lung development we used a cross-fostering technique to restrict the tammar pouch young to milk composition not extending beyond day 25 for 45days of its early postnatal life. These particular time points were selected as our previous study showed that milk protein collected prior to ~day 25 had no developmental effect on mouse embryonic lungs in culture. The comparative analysis of the foster group and control young at day 45 postpartum demonstrated that foster pouch young had significantly reduced lung size. The lungs in fostered young were comprised of large intermediate tissue, had a reduced size of airway lumen and a higher percentage of parenchymal tissue. In addition, expression of marker genes for lung development (BMP4, WNT11, AQP-4, HOPX and SPB) were significantly reduced in lungs from fostered young. Further, to identify the potential bioactive expressed by mammary gland that may have developmental effect on pouch young lungs, we performed proteomics analysis on tammar milk through mass-spectrometry and listed the potential bioactives (PDGF, IGFBP5, IGFBPL1 and EGFL6) secreted in milk that may be involved in regulating pouch young lung development. The data suggest that postnatal lung development in the tammar young is most likely regulated by maternal signalling factors supplied through milk. Copyright © 2016 The Authors.

Monkeypox is a zoonosis clinically similar to smallpox in humans. Recent evidence has shown a potential risk of increased incidence in central Africa. Despite attempts to isolate the virus from wild rodents and other small mammals, no reservoir host has been identified. In 2003,Monkeypox virus (MPXV) was accidentally introduced into the U.S. via the pet trade and was associated with the Gambian pouched rat (Cricetomys gambianus). Therefore, we investigated the potential reservoir competence of the Gambian pouched rat for MPXV by utilizing a combination of in vivo and in vitro methods. We inoculated three animals by the intradermal route and three animals by the intranasal route, with one mock-infected control for each route. Bioluminescent imaging (BLI) was used to track replicating virus in infected animals and virological assays (e.g. real time PCR, cell culture) were used to determine viral load in blood, urine, ocular, nasal, oral, and rectal swabs. Intradermal inoculation resulted in clinical signs of monkeypox infection in two of three animals. One severely ill animal was euthanized and the other affected animal recovered. In contrast, intranasal inoculation resulted in subclinical infection in all three animals. All animals, regardless of apparent or inapparent infection, shed virus in oral and nasal secretions. Additionally, BLI identified viral replication in the skin without grossly visible lesions. These results suggest that Gambian pouched rats may play an important role in transmission of the virus to humans, as they are hunted for consumption and it is possible for MPXV-infected pouched rats to shed infectious virus without displaying overt clinical signs.

As a breakthrough to open up the industrial use of novel environmentally benign packaging material, we propose the first report on portable chitosan-ZnO nano-composite pouches that will serve as elite entrants in smart packaging. A facile, one pot procedure was adopted for the preparation of the C-ZnC films. In order to tune the property of C-ZnC films, four different composite films were prepared by varying the concentration of ZnO. The prepared films were found to be much superior when compared to bare chitosan and other conventional films. Two bacterial strains that commonly contaminate in packed meat were selected as target microbes to elucidate the antimicrobial activity of the prepared C-ZnO film. Detailed investigations revealed that the antimicrobial efficiency is linearly related to the amount of ZnO nano-particles in the composite. The C-2 films exhibited excellent antimicrobial activity and was fabricated into packaging pouches for raw meat. The prepared pouches showed significant action against the microbes in raw meat owing to its complete inhibition of microbial growth on the sixth day of storage at 4°C. The C-2 pouches stand as a top-notch material when compared to polyethylene bag in extending the shelf life of raw meat. Copyright © 2017 Elsevier B.V. All rights reserved.

Colonic volvulus is a relatively uncommon cause of large bowel obstruction usually involving mobile, intra-peritoneal, colonic segments. Congenital or acquired anatomic variation may be associated with an increased risk of colonic volvulus which can occasionally involve retro-peritoneal segments. We report a case of 54-year-old female who presented to our Institution to perform a plain abdominal film series for acute onset of cramping abdominal pain. Both the upright and supine films showed signs of acute colonic obstruction which was thought to be due to an internal hernia of the transverse colon into the lesser sac. The patient was therefore submitted to a multi-detector contrast-enhanced computed tomography (CT). CT findings were initially thought to be consistent with the presumed diagnosis of internal hernia but further evaluation and coronal reformatting clearly depicted the presence of a colonic volvulus possibly resulting from a retro-gastric colon. At surgery, a volvulus of the ascending colon was found and a right hemi-colectomy had to be performed. However, a non rotated midgut with a right-sided duodeno-jejunal flexure and a left sided colon was also found at laparotomy and overlooked in the pre-operative CT. Retrospective evaluation of CT images was therefore performed and a number of CT signs of intestinal malrotation could be identified.

The present animal model of tumor neovascularization most often used by researchers is zebrafish. For studies on human breast cancer cell neovascularization, a new animal model was established to enable a more convenient study of tumor neovascularization. A sodium alginate-gelatin blend gel system was used to design the new animal model. The model was established using rabbit corneal pouch implantation. Then, the animal model was validated by human breast cancer cell lines MCF-7-Kindlin-2 and MCF-7-CMV. The experiment intuitively observed the relationship between tumor and neovascularization, and demonstrated the advantages of this animal model in the study of tumor neovascularization. The use of sodium alginate-gelatin blends to establish tumor neovascularization in a rabbit corneal pouch is a novel and ideal method for the study of neovascularization. It may be a better animal model for expanding the research in this area. Copyright © 2018 Elsevier Inc. All rights reserved.

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.

Oral squamous cell carcinoma (OSCC) is a public health problem. The hamster buccal pouch model is ideal for analyzing the development of OSCC. This research analysed the effects of sunitinib (tyrosine kinase inhibitor) in precancerous lesions induced by 7,12-dimethylbenz(a)anthracene (DMBA) in this model. Thirty-four male hamsters, divided into six groups: control—C (n = 7), acetone—A (n = 12), carbamide peroxide—CP (n = 5 ), acetone and CP—A+CP (n = 8), 1% DMBA in acetone and CP—DA+CP (n = 6), and 1% DMBA in acetone and CP and 4-week treatment with sunitinib—DA+CP+S (n = 7). The aspects evaluated were anatomopathological features (peribuccal area, paws, nose, and fur), histological sections of the hamster buccal pouches (qualitatively analyzed), epithelium thickness, and the rete ridge density (estimated). Sunitinib was unable to attenuate the decrease in weight gain induced by DMBA; no increase in volume was detected in the pouch and/or ulceration, observed in 43% of the animals in the DA+CP group. DA+CP groups presented a significant increase in rete ridge density compared to the control groups (P < 0.01) which was reverted by sunitinib in the DA+CP+S group. Sunitinib seems to have important benefits in early stage carcinogenesis and may be useful in chemoprevention. PMID:24693453

One of the best strategies to prevent the occurrence of oral cancer is to eliminate oral precancers and block their further malignant transformation. Previous studies showed that photosan-mediated photodynamic therapy (photosan-PDT) is very effective for human head and neck cancers. To avoid the systemic photodynamic toxicity of photosan, this study was designed to use a topical photosan-PDT for treatment of DMBA-induced hamster buccal pouch precancerous lesions. Twelve 10-week-old male Syrian golden hamsters were used in this study. DMBA was applied to the left buccal pouches thrice a week for 8 to 10 weeks and mineral oil was painted on the right buccal pouches thrice a week for 8 to 10 weeks as the normal controls. Six hamsters were euthanized for tissue harvest. Precancerous lesions of moderate to severe dysplasia were consistently induced and proven by histological examination. These induced precancerous lesions in the remaining 6 hamsters were used for testing the efficacy of topical photosan-PDT. Before PDT, fluorescence spectroscopy was used to determine when protoporphyrine IX (PpIX) reached its peak level in the lesional epithelial cells after topical application of photosan-gel. We found that PpIX reached its peak level in precancerous lesions about 13.5 min after topical application of photosan-gel. The precancerous lesions in 4 hamsters were treated with topical photosan-PDT using the 635-nm LED light once or twice a week. Complete regression of the precancerous lesions was found after 2-4 PDT treatments by visual and histological examination. Our findings indicate that topical photosan-PDT is a very effective treatment modality for DMBA-induced hamster buccal pouch precancerous lesions.

To assess the therapeutic potential of Lactobacillus acidophilus (LA) for the treatment of pouchitis in a rat model. Sprague Dawley rats underwent proctocolectomy and ileal pouch-anal anastomosis followed by administration of dextran sulfate sodium (DSS) to induce pouchitis. Rats with pouchitis were randomly divided into three groups: no intervention (NI), normal saline (NS, 3 mL/d normal saline for 7 d), and LA (3 mL/d LA at 1× 10 10 colony-forming units for 7 d). General body condition was recorded and pouch specimens were obtained for histological examination. mRNA expression levels of interleukin (IL)-1β, IL-6, IL-10, and tumor necrosis factor-α were determined by RT-PCR. Zonula occludens protein 1 (ZO-1) levels were measured by immunohistochemistry. LA reduced weight loss associated with pouchitis ( P < 0.05) and improved the symptoms of pouchitis in rats. Compared with the NI and NS groups, rats in the LA group showed earlier disappearance of hematochezia (6.17 ± 0.75, 6.50 ± 0.55, 3.17 ± 0.75, P < 0.05) and higher fecal scores (2.67 ± 0.48, 2.50 ± 0.51, 4.42 ± 0.50, respectively, P < 0.05). Histological scores were also lower in the LA group compared with the other two groups (7.17 ± 0.98, 8.00 ± 0.89, 4.00 ± 0.89, respectively, P < 0.05). mRNA expression levels of IL-1β, IL-6, and tumor necrosis factor-α were significantly reduced, while IL-10 mRNA levels were significantly increased in the LA group ( P < 0.05, respectively). ZO-1 protein levels were also significantly increased after administration of LA ( P < 0.05). LA alleviates pouchitis induced by DSS after ileal pouch-anal anastomosis by decreasing pro-inflammatory factors and increasing anti-inflammatory factors, and restoring ZO-1 expression in the mucosa.

Rhythmic motor activity and interlimb co-ordination in the developing pouch young of a wallaby (Macropus eugenii).

1. The forelimb motor behaviour of developing wallaby was studied. A clock-like alternating movement was reactivated whenever the animal was removed from the pouch. 2. Forelimb stepping frequency increased during the first 3 weeks of development, while the phase relationship remained constant. Forelimb activity could be affected by altering the afferent feedback from the contralateral limb, or an increase in ambient temperature. 3. In vitro experiments were performed using an isolated brainstem-spinal cord preparation from animals up to 6 weeks postnatal. Fictive locomotor activity could be evoked by electrical stimulation or bath-applied NMDA (< 10 microM). 4. Bath-applied strychnine (10-25 microM) and bicuculline (10-50 microM) disrupted the phase relationship between motor pools, while rhythmic motor discharge remained in the absence of these inhibitory pathways. 5. The present findings indicate that the pattern generator that underlies the robust forelimb movement during the first journey to the pouch is retained for different motor functions during in-pouch development. The neural network that underlies such behaviour can be divided into two major components, a rhythm generator within each hemicord, and a pattern co-ordinating pathway which involve both glycinergic and GABAergic interneurones.

African giant pouched rats (Cricetomys spp.) are large rodents native to subSaharan Africa. Wild-caught pouched rats identified as Cricetomys ansorgei (n = 49) were imported from Tanzania. A survey of gastrointestinal parasitism by fecal flotation revealed the presence of multiple parasites, including Nippostrongylus spp., Heterakis spp., Trichuris spp., Hymenolepis spp., Raillietina spp., and Eimeria spp. Oral self-administered fenbendazole (150 ppm), topical moxidectin (2 mg/kg), pyrantel pamoate (15 mg/kg), piperazine (100 mg/kg daily), and injectable ivermectin (0.25 mg/kg) were used to determine effective treatment options for the gastrointestinal parasites present in the colony. Pyrantel pamoate in a treat vehicle and piperazine in water bottles were easily administered and significantly reduced the numbers of animals shedding Nippostrongylus spp. and Heterakis spp. during the study. Moxidectin and ivermectin were clinically ineffective at reducing fecal egg shedding. Fenbendazole was most effective at clearing infection with Trichuris spp. Although 10 mg/kg praziquantel was ineffective, a single dose of 30 mg/kg praziquantel significantly reduced the number of African pouched rats that shed cestode embryos. A combination treatment may be necessary to successfully treat all parasites present in any given animal. PMID:28935004

To assess cost-effectiveness of fecal lactoferrin (FL) as the initial diagnostic approach to symptomatic patients with ileal pouch-anal anastomosis (IPAA). Four competing strategies [empiric metronidazole therapy (txMTZ), initial pouch endoscopy with biopsy (testBiop), initial FL assay followed by metronidazole therapy (testFL+MTZ), and initial FL assay followed by pouch endoscopy and biopsy (testFL+Biop)] were modeled in a decision tree. In the base-case, the average cost per patient was $241 for testFL+MTZ, $251 for txMTZ, $405 for testFL+Biop, and $431 for testBiop. The testBiop strategy had greater effectiveness compared with txMTZ but at an incremental cost of $158 per day. The txMTZ strategy was slightly more costly and minimally more effective than testFL+MTZ with an incremental cost effectiveness of just over $12 per day. However, the testFL+MTZ strategy was associated with a 31% absolute reduction in antibiotic exposure compared with the txMTZ strategy. Compared with empiric metronidazole therapy, FL before treatment with metronidazole is less costly with less exposure to antibiotics and less need for endoscopy, with only marginal decrease in effectiveness.

Management of third branchial pouch anomalies - an evolution of a minimally invasive technique.

The management of third branchial pouch anomalies has evolved in recent times with the popularisation of the endoscopic diathermy technique to sclerose the pyriform fossa sinus opening. We present our experience in managing 3 children with third branchial pouch anomalies and propose a minimally invasive management algorithm avoiding open neck surgery. Retrospective case review of 3 patients including demographics, mode of presentation, investigations, management and complications. Three children, two male and one female of mean age 9.6 years presented with painful left anterior neck swelling. Axial neck imaging showed a superficial abscess with air locules and a sinus tract leading towards the left pharynx. Diagnosis was confirmed by endoscopic examination of the pyriform fossa revealing a sinus opening. Two patients underwent open excision; one combined with diathermy to the sinus opening. The last patient was diagnosed at his initial presentation and managed with endoscopic diathermy of the sinus opening combined with percutaneous needle aspiration of the neck abscess at the same sitting. One patient had two recurrences, the first after initial open surgery and the second after the first cautery. Two patients developed temporary hoarseness after the procedure, which resolved within two weeks. All patients were free from recurrences at follow-up. Introduction of the technique of endoscopic diathermy to the pyriform fossa sinus opening in children with third branchial pouch anomalies has revolutionised their management avoiding open and potentially morbid surgery. Our algorithm takes this further by advocating percutaneous needle aspiration of the infective component and performing diathermy to the sinus opening at the first presentation.

Soluble interleukin-2 receptor (sIL-2R) is a glycoprotein derived from α chain of interleukin 2 receptors of mononuclear as well as T-cell membranes. The aims of this study were to detect the changes of serum soluble interleukin-2 receptor (sIL-2R) levels following heavy-ion beam irradiation in the hamster model with cheek pouch carcinoma, as well as to examine the impact of immune status of the hamster cheek pouch carcinoma model using heavy-ion beam irradiation. sIL-2R serum levels were detected by radioimmunoassay (RIA) in 40 hamsters bearing cheek pouch carcinoma prior to and following exposure to heavy-ion beam irradiation, and 8 normal animals served as the control. The sIL-2R serum level in hamster cheek pouch carcinoma model was significantly increased as compared to the normal control group (P<0.05). Results showed that an increase in the irradiation dose led to a gradual decrease in the sIL-2R serum level. Additionally, a statistical significance was observed compared to the tumor group (P<0.05). In conclusion, alterations in serum sIL-2R expression have an effect on the hamsters cheek pouch carcinoma model subsequent to heavy-ion beam irradiation. An increase in the irradiation dose indicated a decreased tendency in serum sIL-2R content. Detection of serum level changes may lead to an improved understanding of heavy-ion irradiation in vivo immune status, which is crucial for clinical diagnosis and prognosis. It can also provide a sensitive indicator to help estimate the effects of heavy-ion cancer targets. PMID:24748984

Intestinal obstruction attributable to internal hernia as a cause is a rare phenomenon with a reported incidence of 0.6%-5.8%. Internal hernias ensuing as a result of defect in the pouch of Douglas is extremely rare with only six such cases reported so far in the literature. We present a case of 74-year-old posthysterectomy status female who presented with features of intestinal obstruction. Intraoperatively, the site of obstruction was found to be a rent in the peritoneum of the pouch of Douglas through which a loop of ileum was found herniating. The viability of the bowel was confirmed, and the defect was closed. The postoperative course was uneventful. This report presents an extremely rare type of internal hernia caused by defect in the pouch of Douglas and review of the literature so far available.

Pregnancy outcomes and community health: the POUCH study of preterm delivery.

In light of the social/ethnic disparity in preterm delivery (PTD) rates, the Pregnancy Outcomes and Community Health (POUCH) Study takes a broad view of the determinants of PTD by attempting to link underlying biological and psychosocial factors. The relationships between placental pathology, maternal biomarkers, and antecedent psychosocial factors are evaluated in three hypothesised pathways of PTD - one characterised primarily by infection, one by maternal vascular disease, and one by premature elevations in corticotropin releasing hormone in the absence of histological evidence of placental pathology. Within each pathway, an emphasis is placed on understanding the roles of stress and of maternal serum alpha-fetoprotein, an early biomarker associated with PTD. The POUCH Study enrolls pregnant women from five Michigan communities. Information about these women and their environments is gathered through detailed interviews and collection of biological samples including hair, urine, saliva, blood, vaginal fluid, and vaginal smear at 15-26 weeks of gestation. We have chosen to focus on the second trimester--a time when pathological processes may have evolved to a detectable stage, but generally before the onset of biological changes that accompany labour. This focus is consistent with the long-range goal of early detection/intervention and prevention of PTD.

To decide whether the identical topography of short- and middle-wavelength cone photoreceptors in two species of rodents reflects the presence of both opsins in all cone cells. Double-label immunocytochemistry using antibodies directed against short-wavelength (S)-and middle- to long-wavelength (M/L)-sensitive opsin were used to determine the presence of visual pigments in cones of two species of rodents, the Siberian hamster (Phodopus sungorus) and the pouched mouse (Saccostomus campestris) from South Africa. Topographical distribution was determined from retinal whole-mounts, and the colocalization of visual pigments was examined using confocal laser scanning microscopy. Opsin colocalization was also confirmed in consecutive semithin tangential sections. The immunocytochemical results demonstrate that in both the Siberian hamster and the pouched mouse all retinal cones contain two visual pigments. No dorsoventral gradient in the differential expression of the two opsins is observed. The retina of the Siberian hamster and the pouched mouse is the first example to show a uniform coexpression of M and S cone opsins in all cones, without any topographical gradient in opsin expression. This finding makes these two species good models for the study of molecular control mechanisms in opsin coexpression in rodents, and renders them suitable as sources of dual cones for future investigations on the role and neural connections of this cone type.

Hamster cheek pouches were exposed to 2-chloroethyl ethyl sulfide [CEES, half-mustard gas (HMG)] at a concentration of 0.4, 2.0, or 5.0 mg/ml for 1 or 5 min. Twenty-four hours post-HMG exposure, tissue damage was assessed by both stereomicrography and optical coherence tomography (OCT). Damage that was not visible on gross visual examination was apparent in the OCT images. Tissue changes were found to be dependent on both HMG concentration and exposure time. The submucosal and muscle layers of the cheek pouch tissue showed the greatest amount of structural alteration. Routine light microscope histology was performed to confirm the OCT observations.

Treatment of subclinical carriers of Streptococcus equi subsp. equi with a gelatine-penicillin formulation deposited in the guttural pouch has been empirically proposed, but data on local tissue penicillin concentrations after treatment are lacking. We analysed tissue levels of penicillin after administration into the guttural pouches of four healthy horses. Two horses received local treatment with gelatine-penicillin and two horses received local treatment with an intramammary formulation of penicillin. Tissues were harvested for analysis either 12 or 24 h later. Results indicate that local treatment may be effective, but more research on optimal drug formulations in a larger sample size is warranted. © 2016 Australian Veterinary Association.

Propionyl-l-carnitine (pLc) exerts protective effects in different experimental models of ischemia-reperfusion (I/R). The aim of the present study was to assess the effects of intravenously and topically applied pLc on microvascular permeability increase induced by I/R in the hamster cheek pouch preparation. The hamster cheek pouch microcirculation was visualized by fluorescence microscopy. Microvascular permeability, leukocyte adhesion to venular walls, perfused capillary length, and capillary red blood cell velocity (V(RBC)) were evaluated by computer-assisted methods. E-selectin expression was assessed by in vitro analysis. Lipid peroxidation and reactive oxygen species (ROS) formation were determined by thiobarbituric acid-reactive substances (TBARS) and 2'-7'-dichlorofluorescein (DCF), respectively. In control animals, I/R caused a significant increase in permeability and in the leukocyte adhesion in venules. Capillary perfusion and V(RBC) decreased. TBARS levels and DCF fluorescence significantly increased compared with baseline. Intravenously infused pLc dose-dependently prevented leakage and leukocyte adhesion, preserved capillary perfusion, and induced vasodilation at the end of reperfusion, while ROS concentration decreased. Inhibition of nitric oxide synthase prior to pLc caused vasoconstriction and partially blunted the pLc-induced protective effects; inhibition of the endothelium-derived hyperpolarizing factor (EDHF) abolished pLc effects. Topical application of pLc on cheek pouch membrane produced the same effects as observed with intravenous administration. pLc decreased the E-selectin expression. pLc prevents microvascular changes induced by I/R injury. The reduction of permeability increase could be mainly due to EDHF release induce vasodilatation together with NO. The reduction of E-selectin expression prevents leukocyte adhesion and permeability increase.

E-selectin expression was assessed by in vitro analysis. Lipid peroxidation and reactive oxygen species (ROS) formation were determined by thiobarbituric acid-reactive substances (TBARS) and 2′-7′-dichlorofluorescein (DCF), respectively. Results In control animals, I/R caused a significant increase in permeability and in the leukocyte adhesion in venules. Capillary perfusion and VRBC decreased. TBARS levels and DCF fluorescence significantly increased compared with baseline. Intravenously infused pLc dose-dependently prevented leakage and leukocyte adhesion, preserved capillary perfusion, and induced vasodilation at the end of reperfusion, while ROS concentration decreased. Inhibition of nitric oxide synthase prior to pLc caused vasoconstriction and partially blunted the pLc-induced protective effects; inhibition of the endothelium-derived hyperpolarizing factor (EDHF) abolished pLc effects. Topical application of pLc on cheek pouch membrane produced the same effects as observed with intravenous administration. pLc decreased the E-selectin expression. Conclusions pLc prevents microvascular changes induced by I/R injury. The reduction of permeability increase could be mainly due to EDHF release induce vasodilatation together with NO. The reduction of E-selectin expression prevents leukocyte adhesion and permeability increase. PMID:21423374

OBJECTIVE To evaluate the use of a laparoscopic specimen retrieval pouch for removal of intact or fragmented cystic calculi from standing horses. DESIGN Retrospective case series. ANIMALS 8 horses (5 geldings and 3 mares) with cystic calculi. PROCEDURES Physical examination and cystoscopic, ultrasonographic, and hematologic evaluations of urinary tract function were performed for each horse. A diagnosis of cystic calculus was made on the basis of results of cystoscopy and ultrasonography. Concurrent urolithiasis or other urinary tract abnormalities identified during preoperative evaluation were recorded. Horses were sedated and placed in standing stocks, and the perineum was aseptically prepared. Direct access to the urinary bladder was gained in geldings via perineal urethrotomy or in mares by a transurethral approach. Calculi were visualized endoscopically, manipulated into the retrieval pouch, and removed intact or fragmented (for larger calculi). RESULTS For 4 geldings and 1 mare, fragmentation was necessary to facilitate calculus removal. Mean duration of surgery was 125 minutes, and trauma to the urinary bladder and urethra was limited to areas of hyperemia and submucosal petechiation. No postoperative complications were encountered for any horse. When lithotripsy was required, the retrieval pouch provided an effective means of stabilizing calculi and containing the fragments for removal. CONCLUSIONS AND CLINICAL RELEVANCE Use of the laparoscopic specimen retrieval pouch was an effective, minimally traumatic method for retrieving cystic calculi from standing horses. The pouch protected the urinary bladder and urethra from trauma during calculus removal and allowed for stabilization, containment, and fragmentation of calculi when necessary.

Tunguska, 1908: the gas pouch and soil fluidization hypothesis

2012-01-01

The Siberian taiga explosion of 30 June 1908 remains one of the great mysteries of the 20th century: millions of trees put down over an area of 2200 km2 without trace of a crater or meteorite fragments. Hundred years of failed searches have followed, resulting in as many flawed hypothesis which could not offer satisfactory explanations: meteorite, comet, UFO, etc. In the author's opinion, the cause is that the energy the explorers looked for was simply not there! The author's hypothesis is that a meteoroid encountered a gas pouch in the atmosphere, producing a devastating explosion, its effects being amplified by soil fluidization.

The pharmacokinetics (PK) of the photosensitizer tetra(m-hydroxyphenyl)chlorin (mTHPC) was measured by optical fiber-based light-induced fluorescence spectroscopy (LIFS) in the normal and tumoral cheek pouch mucosa of 29 Golden Syrian hamsters with chemically induced squamous cell carcinoma. Similar measurements were carried out on the normal oral cavity mucosa of five patients up to 30 days after injection. The drug doses were between 0.15 and 0.3 mg per kg of body weight (mg/kg), and the mTHPC fluorescence in the tissue was excited at 420 nm. The PK in both human and hamster exhibited similar behavior although the PK in the hamster mucosa was slightly delayed in comparison with that of its human counterpart. The mTHPC fluorescence signal of the hamster mucosa was smaller than that of the human mucosa by a factor of about 3 for the same injected drug dose. A linear correlation was found between the fluorescence signal and the mTHPC dose in the range from 0.075 to 0.5 mg/kg at times between 8 and 96 h after injection. No significant selectivity in mTHPC fluorescence between the tumoral and normal mucosa of the hamsters was found at any of the applied conditions. The sensitivity of the normal and tumoral hamster cheek pouch mucosa to mTHPC photodynamic therapy as a function of the light dose was determined by light irradiation at 650 nm and 150 mW/cm2, 4 days after the injection of a drug dose of 0.15 mg/kg. These results were compared with irradiations of the normal oral and normal and tumoral bronchial mucosa of 37 patients under the same conditions. The reaction to PDT of both types of human mucosae was considerably stronger than that of the hamster cheek pouch mucosa. The sensitivity to PDT became comparable between hamster and human mucosa when the drug dose for the hamster was increased to 0.5 mg/kg. A significant therapeutic selectivity between the normal and neoplastic hamster cheek pouch was observed. Less selectivity was found following irradiations of

In Taiwan, oral cancer has becomes the fastest growth male cancer disease due to the betel nut chewing habit combing with smoking and alcohol-drinking lifestyle of people. In order to eliminate the systemic phototoxic effect of 5-aminolevulinic acid (ALA), this study was designed to use a topical ALA-mediated PDT for treatment of DMBA-induced hamster buccal pouch precancerous lesions. DMBA was applied to one of the buccal pouches of hamsters thrice a week for 10 to 12 weeks. Cancerous lesions were induced and proven by histological examination. These DMBA-induced cancerous lesions were used for testing the efficacy of topical ALA-mediated PDT. Before PDT, fluorescence spectroscopy was used to determine when ALA reached its peak level in the lesional epithelial cells after topical application of ALA gel. We found that ALA reached its peak level in precancerous lesions about 2.5 hrs after topical application of ALA gel. The cancerous lesions in hamsters were then treated with topical ALA -mediated PDT with light exposure dose of 150 J/cm2 using LED 635 nm fiber-guided light device. Visual examination demonstrated that adjuvant topical ALA -mediated PDT group has shown better therapeutic results in compared to those of non-adjuvant topical ALA-mediated PDT group for DMBA-induced hamster buccal pouch precancerous lesions.

Lipomas of the colon are relatively rare benign soft tissue tumors derived from mature adipocytes of mesenchymatic origin. During colonoscopy, surgery or autopsy they are generally discovered incidentally. Most cases are asymptomatic, with a small tumor size, and do not need any special treatment. However, in the cases with larger in size of tumor some symptoms such as anemia, abdominal pain, constipation, diarrhea, bleeding, or intussusception may be presented. We reported a 47-year-old woman with colonic intussusception in the descending colon caused by colonic lipoma and diagnosed after surgical exploration for obstructive colonic mass. PMID:28224035

Giant African pouched rats recently have been used as mine-detection animals in Mozambique. To provide an example of the wide range of problems to which operant conditioning procedures can be applied and to illustrate the common challenges often faced in applying those procedures, this manuscript briefly describes how the rats are trained and used operationally. To date, the rats have performed well and it appears they can play a valuable role in humanitarian demining.

Background: We report a case of a neonate with proximal spinal muscular atrophy (SMA) type 1 (also known as Werdnig-Hoffmann disease or severe infantile acute SMA) associated with a Blake's pouch cyst; a malformation that is currently classified within the spectrum of Dandy-Walker complex. The association of the two conditions has not been previously reported in the English literature. A comprehensive review of the pertinent literature is presented. Case Description: A male neonate was noted to have paucity of movement of the four limbs with difficulty of breathing and poor feeding soon after birth. Respiratory distress with tachypnea, necessitated endotracheal intubation and mechanical ventilation. Pregnancy was uneventful except for decreased fetal movements reported by the mother during the third trimester. Neurological examination revealed generalized hypotonia with decreased muscle power of all limbs, nonelicitable deep tendon jerks, and occasional tongue fasciculations. Molecular genetic evaluation revealed a homozygous deletion of both exons 7 and 8 of the survival motor neuron 1 (SMN1) gene, and exon 5 of the neuronal apoptosis inhibitory protein (NAIP) gene on the long arm of chromosome 5 consistent with Werdnig-Hoffmann disease (SMA type 1). At the age of 5 months, a full anterior fontanelle and abnormal increase of the occipito-frontal circumference were noted. Computed tomographic (CT) scan and magnetic resonance imaging (MRI) of the brain revealed a tetraventricular hydrocephalus and features of Blake's pouch cyst of the fourth ventricle. Conclusions: This case represents a previously unreported association of Blake's pouch cyst and SMA type 1. PMID:25225621

Oral cancer has becomes the most prominent cancer disease in recent years in Taiwan. The reason is the betel nut chewing habit combing with smoking and alcohol-drinking lifestyle of people results in oral cancer becomes the fastest growth incident cancer amongst other major cancer diseases. In previous studies showed that photosan, haematoporphyrin derivative (HPD), has demonstrated effective PDT results on human head and neck disease studies. To avoid the systemic phototoxic effect of photosan, this study was designed to use a topical photosan-mediated PDT for treatment of DMBA-induced hamster buccal pouch cancerous lesions. DMBA was applied to one of the buccal pouches of hamsters thrice a week for 10 to 12 weeks. Cancerous lesions were induced and proven by histological examination. These DMBA-induced cancerous lesions were used for testing the efficacy of topical photosan-mediated PDT. Before PDT, fluorescence spectroscopy was used to determine when photosan reached its peak level in the lesional epithelial cells after topical application of photosan gel. We found that photosan reached its peak level in cancerous lesions about 13.5 min after topical application of photosan gel. The cancerous lesions in hamsters were then treated with topical photosan-mediated PDT (fluence rate: 600 mW/cm2; light exposure dose 200 J/cm2) using the portable Lumacare 635 nm fiber-guided light device. Visual examination demonstrated that topical photosan-mediated PDT was an applicable treatment modality for DMBA-induced hamster buccal pouch cancerous lesions.

Continent catheterizable ileal pouches require regular irrigations to reduce the risk of bacteriuria and urinary tract infections (UTIs). Our aim was to compare the UTI rate, patient friendliness, and costs of standard sterile irrigation versus irrigation with tap water. Twenty-three patients participated in a prospective randomized two-arm crossover single-center trial. Aseptic intermittent self-catheterization (ISC) combined with sterile sodium chloride (NaCl) 0.9% irrigation was compared with clean ISC and irrigation with tap water (H(2)O) during two study periods of 90 d each. Patients underwent daily pouch irrigations with NaCl 0.9% solution or tap water. Urine nitrite dipstick tests were evaluated daily; urine culture (UC) and patient friendliness were evaluated monthly. Costs were documented. A total of 3916 study days with nitrite testing and irrigation were analyzed, 1876 (48%) in the NaCl arm and 2040 (52%) in the H(2)O arm. In the NaCl arm, 418 study days (22%) with nitrite-positive dipsticks were recorded, 219 d (11%) in the H(2)O arm, significantly fewer (p=0.01). Of the 149 UCs, 96 (64%) were positive, 48 in each arm, revealing a total of 16 different germs. All patients preferred the H(2)O method. Monthly costs were up to 20 times lower in the H(2)O arm. Pouch irrigation with sterile NaCl 0.9% solution and tap water had comparable rates of positive UC. Irrigation with tap water significantly lowered the incidence of nitrite-positive study days and was substantially less costly and more patient friendly than NaCl irrigation. We therefore recommend the use of tap water (or bottled water) instead of sterile NaCl 0.9% solution for daily irrigation of continent catheterizable ileal pouches.

Restorative Procedures in Colonic Crohn Disease

PubMed Central

Martin, Sean T.; Vogel, Jon D.

2013-01-01

Surgical management for refractory Crohn colitis often involves creation of a temporary or permanent stoma. Traditionally, the procedure of choice has been a total proctocolectomy with permanent ileostomy. However, restorative procedures that help to avoid a permanent stoma are being used with more frequency. In this article, the authors will address these procedures, including colocolonic anastomosis, ileorectal anastomosis, ileal pouch rectal anastomosis, and ileal pouch anal anastomosis. Factors that may influence one's decision to perform these procedures, such as patient age and nutritional status, medical comorbidities, sphincter function, desire to avoid a permanent ostomy, and prior medical therapy, will be discussed. Functional outcomes regarding these procedures will also be described. One should keep in mind that surgery does not cure Crohn disease and that postoperative long-term management is essential in preventing progression or recurrence of disease. PMID:24436657

Manometry of the Upper Gut Following Roux-en-Y Gastric Bypass Indicates That the Gastric Pouch and Roux Limb Act as a Common Cavity.

2015-10-01

The motility of the upper gut after Roux-en-Y gastric bypass (RYGBP) is underexplored. We aimed to investigate the oesophago-gastro-Roux limb motor activity during fasting and after food intake. Eighteen morbidly obese patients were examined at least 2 years after RYGBP. A high-resolution manometry catheter was positioned to straddle the oesophagogastric junction, the gastric pouch and the proximal Roux limb using transmucosal potential difference measurements. Three patients with vertical banded gastroplasty (VBG) were also studied. During the fasting state, the gastric pouch had low or no activity whereas the Roux limb exhibited regular migrating motility complexes (MMCs) being initiated just distal to gastroenteroanastomosis. Median cycle duration was 72 min, and the median propagating velocity of the phase III MMC phase was 2.7 cm/min (n = 8). When patients were asked to eat until they felt comfortably full, intraluminal pressure increased by 6 to 8 cmH₂O without any significant difference between gastric pouch and the Roux limb (n = 9). The increased intraluminal pressure following food intake correlated neither to weight loss nor to meal size or rate of eating. A successful RYGBP is associated with MMC in the Roux limb during fasting. The gastric pouch and the Roux limb behaved as a common cavity during food ingestion. Data do not support the hypothesis that the alimentary limb pressure in response to food intake influences either meal size or weight loss.

The pathogenesis of diarrhea in intestinal inflammatory states is a multifactorial process involving the effects of inflammatory mediators on epithelial transport function. The effect of colonic inflammation on the gene expression of DRA (downregulated in adenoma), a chloride-sulfate anion transporter that is mutated in patients with congenital chloridorrhea, was examined in vivo as well as in an intestinal epithelial cell line. DRA mRNA expression was diminished five- to sevenfold in the HLA-B27/beta2m transgenic rat compared with control. In situ hybridization showed that DRA, which is normally expressed in the upper crypt and surface epithelium of the colon, was dramatically reduced in the surface epithelium of the HLA-B27/beta2m transgenic rat, the interleukin-10 (IL-10) knockout mouse with spontaneous colitis, and in patients with ulcerative colitis. Immunohistochemistry demonstrated that mRNA expression of DRA reflected that of protein expression in vivo. IL-1beta reduced DRA mRNA expression in vitro by inhibiting gene transcription. The loss of transport function in the surface epithelium of the colon by attenuation of transporter gene expression, perhaps inhibited at the level of gene transcription by proinflammatory cytokines, may play a role in the pathogenesis of diarrhea in colitis.

Aberrant arachidonic acid metabolism, especially altered cyclooxygenase and 5-lipoxygenase (LOX) activities, has been associated with chronic inflammation as well as carcinogenesis in human oral cavity tissues. Here, we examined the effect of Zyflamend, a product containing 10 concentrated herbal extracts, on development of 7,12-dimethylbenz[alpha]anthracene (DMBA)-induced inflammation and oral squamous cell carcinoma (SCC). A hamster cheek pouch model was used in which 0.5% DMBA was applied topically onto the left cheek pouch of male Syrian golden hamsters either three times per week for 3 weeks (short term) or 6 weeks (long term). Zyflamend was then applied topically at one of three different doses (25, 50 and 100 microl) onto the left cheek pouch three times for 1 week (short-term study) or chronically for 18 weeks. Zyflamend significantly reduced infiltration of inflammatory cells, incidence of hyperplasia and dysplastic lesions, bromodeoxyuridine-labeling index as well as number of SCC in a concentration-dependent manner. Application of Zyflamend (100 microl) reduced formation of leukotriene B(4) (LTB(4)) by 50% compared with DMBA-treated tissues. The reduction of LTB(4) was concentration dependent. The effect of Zyflamend on inhibition of LTB(4) formation was further confirmed with in vitro cell-based assay. Adding LTB(4) to RBL-1 cells, a rat leukemia cell line expressing high levels of 5-LOX and LTA(4) hydrolase, partially blocked antiproliferative effect of Zyflamend. This study demonstrates that Zyflamend inhibited LTB(4) formation and modulated adverse histopathological changes in the DMBA-induced hamster cheek pouch model. The study suggests that Zyflamend might prevent oral carcinogenesis at the post-initiation stage.

Congenital syphilis remains a major public health problem worldwide, and its incidence is increasing in the United States. This review highlights the ongoing problem of this preventable infection, and discusses vertical transmission and clinical manifestations while providing a practical algorithm for the evaluation and management of infants born to mothers with reactive serologic tests for syphilis. Every case of congenital syphilis must be seen as a failure of our public health system to provide optimal prenatal care to pregnant women, as congenital syphilis can be prevented by early and repeated prenatal serologic screening of mothers and penicillin treatment of infected women, their sexual partners, and their newborn infants.

Congenital syphilis is a serious, preventable, and nationally notifiable disease. Despite the existence of a surveillance case definition, congenital syphilis is sometimes classified differently using an algorithm on the Centers for Disease Control and Prevention's case reporting form. We reviewed Louisiana's congenital syphilis electronic reporting system for investigations of infants born from January 2010 to October 2011, abstracted data required for classification, and applied the surveillance definition and the algorithm. We calculated the sensitivities and specificities of the algorithm and Louisiana's classification using the surveillance definition as the surveillance gold standard. Among 349 congenital syphilis investigations, the surveillance definition identified 62 cases. The algorithm had a sensitivity of 91.9% and a specificity of 64.1%. Louisiana's classification had a sensitivity of 50% and a specificity of 91.3% compared with the surveillance definition. The differences between the algorithm and the surveillance definition led to misclassification of congenital syphilis cases. The algorithm should match the surveillance definition. Other state and local health departments should assure that their reported cases meet the surveillance definition.

Alveolar ridge augmentation by connective tissue grafting using a pouch method and modified connective tissue technique: A prospective study.

Localized alveolar ridge defect may create physiological and pathological problems. Developments in surgical techniques have made it simpler to change the configuration of a ridge to create a more aesthetic and more easily cleansable shape. The purpose of this study was to compare the efficacy of alveolar ridge augmentation using a subepithelial connective tissue graft in pouch and modified connective tissue graft technique. In this randomized, double blind, parallel and prospective study, 40 non-smoker individuals with 40 class III alveolar ridge defects in maxillary anterior were randomly divided in two groups. Group I received modified connective tissue graft, while group II were treated with subepithelial connective tissue graft in pouch technique. The defect size was measured in its horizontal and vertical dimension by utilizing a periodontal probe in a stone cast at base line, after 3 months, and 6 months post surgically. Analysis of variance and Bonferroni post-hoc test were used for statistical analysis. A two-tailed P < 0.05 was considered to be statistically significant. Mean values in horizontal width after 6 months were 4.70 ± 0.87 mm, and 4.05 ± 0.89 mm for group I and II, respectively. Regarding vertical heights, obtained mean values were 4.75 ± 0.97 mm and 3.70 ± 0.92 mm for group I and group II, respectively. Within the limitations of this study, connective tissue graft proposed significantly more improvement as compare to connective tissue graft in pouch.

Colon volvulus (CV) is the twisting or rotation of an intestinal segment over the mesenterium, which causes occlusion and vascular compromise. It is a frequent disease in individuals over 65 years-old. We report a young patient with right CV and necrosis. A 17 year-old male with clinical findings of acute abdomen presented in the emergency room. During the surgical procedure, a right sided was found, CV with ileocecal valve and caecum ischemia and right colon necrosis with mesenteric vessels thrombosis. The case presented begun with sudden abdominal pain, with intestinal occlusion data, and widespread peritoneal rebound tenderles which suggested an intestinal occlusion. A simple abdomen Rx showed prominent right side colon distention with air levels in small bowel and a "coffee bean" image, suggestive of CVA hemicolectomy with termino-lateral ileocolic anastomosis was performed. Right-sided CV is considered as congenital in origin. They corresponded to 21% of cases in Mexico, with an average age of presentation at 62 years. The CV represents 10% of the causes of large bowel obstruction in Mexico. This is the first case in young people reported in Mexican literature.

The association between pediatric cancer and congenital abnormalities is well known but, there is no exclusive data on the neonatal period and the underlying etiopathogenic mechanisms are unknown. First, to analyze the frequency of neonatal tumours associated with congenital abnormalities; and second, to comment on the likely etiopathogenic hypotheses of a relationship between neonatal tumours and congenital abnormalities. Historical series of neonatal tumours from La Fe University Children's Hospital in Valencia (Spain), from January 1990 to December 1999. Histological varieties of neonatal tumours and associated congenital abnormalities were described. A systematic review of the last 25 years was carried out using Medline, Cancerlit, Index Citation Science and Embase. The search profile used was the combination of "neonatal/congenital-tumors/cancer/neoplasms" and "congenital malformations/birth defects". 72 neonatal tumours were identified (2.8% of all pediatric cancers diagnosed in our hospital) and in 15 cases (20.8%) there was some associated malformation, disease or syndrome. The association between congenital abnormalities and neonatal tumours were: a) angiomas in three patients: two patients with congenital heart disease with a choanal stenosis, laryngomalacia; b) neuroblastomas in two patients: horseshoe kidney with vertebral anomalies and other with congenital heart disease; c) teratomas in two patients: one with cleft palate with vertebral anomalies and other with metatarsal varus; d) one tumour of the central nervous system with Bochdaleck hernia; e) heart tumours in four patients with tuberous sclerosis; f) acute leukaemia in one patient with Down syndrome and congenital heart disease; g) kidney tumour in one case with triventricular hydrocephaly, and h) adrenocortical tumour: hemihypertrophy. The publications included the tumours diagnosed in different pediatric periods and without unified criteria to classify the congenital abnormalities. Little data

Horseshoe kidney is a congenital malformation in which the bilateral kidneys are fused. It is frequently complicated by other congenital malformations and is often accompanied by anomalies of the ureteropelvic and vascular systems, which must be evaluated to avoid iatrogenic injury. We report a case of laparoscopic high anterior resection of rectosigmoid colon cancer associated with a horseshoe kidney using preoperative 3D-CT angiography. A 52-year-old Japanese man with lower abdominal pain underwent lower endoscopy, revealing a type 2 lesion in the rectosigmoid colon. He was diagnosed with rectosigmoid colon cancer with multiple lung metastases and a horseshoe kidney on computed tomography (CT) scan. Three-dimensional (3D)-CT angiography showed an aberrant renal artery at the isthmus from 3 cm under the inferior mesenteric artery (IMA) branch of the aorta. Laparoscopic anterior rectal resection was performed. During the operation, the inferior mesenteric artery, left ureter, left gonadal vessels, and hypogastric nerve plexus could be seen passing over the horseshoe kidney isthmus and were preserved. The left branch of aberrant renal artery that was close to IMA was also detected and preserved. To prevent intraoperative misidentification, 3D-CT angiography should be performed preoperatively to ascertain the precise positional relationships between the extra renal arteries and the kidney. We always must consider anomalous locations of renal vessels, ureter, gonadal vessels, and lumbar splanchnic nerve to avoid laparoscopic iatrogenic injury in patients with a horseshoe kidney.

The use of smokeless tobacco products (STPs) can cause many serious health problems. The oral microbiota plays important roles in oral and systemic health, and the disruption in the oral microbial population is linked to periodontal disease and other health problems. To assess the impact of smokeless tobacco on oral microbiota in vivo, high-throughput sequencing was used to examine the oral microbiota present in Syrian Golden hamster cheek pouches. Sixteen hamsters were divided into four groups and treated with the STP Grizzly snuff (0, 2.5, 25, or 250 mg) twice daily for 4 weeks. After 0, 1, 2, 3, and 4 weeks of treatment, bacterial genomic DNA was extracted from oral swabs sampled from the cheek pouches of the hamsters. The oral bacterial communities present in different hamster groups were characterized by sequencing the hypervariable regions V1-V2 and V4 of 16S rRNA using the Illumina MiSeq platform. Fifteen phyla, 27 classes, 59 orders, 123 families, and 250 genera were identified from 4,962,673 sequence reads from the cheek pouch samples. The bacterial diversity and taxonomic abundances for the different treatment groups were compared to the non-treated hamsters. Bacterial diversity was significantly decreased after 4 weeks of exposure to 2.5 mg, and significantly increased by exposure to 250 mg STP. Treatment with 250 mg STP significantly increased Firmicutes, transiently increased Cyanobacteria and TM7, and decreased Bacteroidetes and Fusobacteria compared to the control group. At the genus level, 4 weeks of administration of 250 mg STP significantly increased Granulicatella, Streptococcus, Oribacterium, Anaerococcus, Acidaminococcus, Actinomyces, Eubacterium, Negativicoccus, and Staphylococcus, and decreased Bacteroides, Buleidia, Dialister, and Leptotrichia, and transiently decreased Arcanobacterium compared to the control group. For the first time, an animal model was used for evaluating the effects of STP on oral microbiota by metagenomic

We present a case of mature congenital orbital teratoma managed with lid-sparing exenteration and dermis fat graft. This is a case report on the management of congenital orbital teratoma. A full-term baby was born in Fiji with prolapsed right globe which was surrounded by a nonpulsatile, cystic mass. Clinical and imaging features were consistent with congenital orbital teratoma. Due to limited surgical expertise, the patient was transferred to Adelaide, Australia for further management. The patient underwent a lid-sparing exenteration with frozen section control of the apical margin. A dermis fat graft from the groin was placed beneath the lid skin to provide volume. Histopathology revealed mature tissues from each of the three germ cell layers which confirmed the diagnosis of mature teratoma. We describe the successful use of demis fat graft in socket reconstruction following lid-sparing exenteration for congenital orbital teratoma.

Congenital plasminogen deficiency is caused by mutations in PLG, the gene coding for production of the zymogen plasminogen, and is an ultrarare disorder associated with abnormal accumulation or growth of fibrin-rich pseudomembranous lesions on mucous membranes. Left untreated, these lesions may impair organ function and impact quality of life. Plasminogen replacement therapy should provide an effective treatment of the manifestations of congenital plasminogen deficiency. An open-label phase 2/3 study of human Glu-plasminogen administered IV at 6.6 mg/kg every 2 to 4 days in 15 patients with congenital plasminogen deficiency is ongoing. Reported here are data on 14 patients who completed at least 12 weeks of treatment. The primary end point was an increase in trough plasminogen activity levels by at least an absolute 10% above baseline. The secondary end point was clinical success, defined as ≥50% improvement in lesion number/size or functionality impact from baseline. All patients achieved at least an absolute 10% increase in trough plasminogen activity above baseline. Clinical success was observed in all patients with clinically visible (conjunctiva and gingiva), nonvisible (nasopharynx, bronchus, colon, kidney, cervix, and vagina), and wound-healing manifestations of the disease. Therapeutic effects were rapid, as all but 2 lesions resolved or improved after 4 weeks of treatment. Human Glu-plasminogen was well tolerated in both children and adults. This study provides critical first evidence of the clinical utility of ongoing replacement therapy with human Glu-plasminogen for the treatment of children and adults with congenital plasminogen deficiency. This trial was registered at www.clinicaltrials.gov as #NCT02690714. PMID:29321155

Giant congenital melanocytic nevus*

2013-01-01

Giant congenital melanocytic nevus is usually defined as a melanocytic lesion present at birth that will reach a diameter ≥ 20 cm in adulthood. Its incidence is estimated in <1:20,000 newborns. Despite its rarity, this lesion is important because it may associate with severe complications such as malignant melanoma, affect the central nervous system (neurocutaneous melanosis), and have major psychosocial impact on the patient and his family due to its unsightly appearance. Giant congenital melanocytic nevus generally presents as a brown lesion, with flat or mammilated surface, well-demarcated borders and hypertrichosis. Congenital melanocytic nevus is primarily a clinical diagnosis. However, congenital nevi are histologically distinguished from acquired nevi mainly by their larger size, the spread of the nevus cells to the deep layers of the skin and by their more varied architecture and morphology. Although giant congenital melanocytic nevus is recognized as a risk factor for the development of melanoma, the precise magnitude of this risk is still controversial. The estimated lifetime risk of developing melanoma varies from 5 to 10%. On account of these uncertainties and the size of the lesions, the management of giant congenital melanocytic nevus needs individualization. Treatment may include surgical and non-surgical procedures, psychological intervention and/or clinical follow-up, with special attention to changes in color, texture or on the surface of the lesion. The only absolute indication for surgery in giant congenital melanocytic nevus is the development of a malignant neoplasm on the lesion. PMID:24474093

MucoCept is a biotherapeutic for prevention of HIV-1 infection in women and contains a human, vaginal Lactobacillus jensenii that has been genetically enhanced to express the HIV-1 entry inhibitor, modified cyanovirin-N (mCV-N). The objective of this study was to develop a solid vaginal dosage form that supports sustained vaginal colonization of the MucoCept Lactobacillus at levels previously shown, with freshly prepared cultures, to protect macaques from SHIV infection and to test this formulation in a macaque vaginal colonization model. Vaginally disintegrating tablets were prepared by lyophilizing the formulated bacteria in tablet-shaped molds, then packaging in foil pouches with desiccant. Disintegration time, potency and stability of the tablets were assessed. For colonization, non-synchronized macaques were dosed vaginally with either one tablet or five tablets delivered over five days. Vaginal samples were obtained at three, 14, and 21 days post-dosing and cultured to determine Lactobacillus colonization levels. To confirm identity of the MucoCept Lactobacillus strain, genomic DNA was extracted from samples on days 14 and 21 and a strain-specific PCR was performed. Supernatants from bacteria were tested for the presence of the mCV-N protein by Western blot. The tablets were easy to handle, disintegrated within two minutes, potent (5.7x1011 CFU/g), and stable at 4°C and 25°C. Vaginal administration of the tablets to macaques resulted in colonization of the MucoCept Lactobacillus in 66% of macaques at 14 days post-dosing and 83% after 21 days. There was no significant difference in colonization levels for the one or five tablet dosing regimens (p=0.88 Day 14, p=0.99 Day 21). Strain-specific PCR confirmed the presence of the bacteria even in culture-negative macaques. Finally, the presence of mCV-N protein was confirmed by Western blot analysis using a specific anti-mCV-N antibody.

Based on distinct epidemiologic features of Chinese type 2 diabetes mellitus (T2DM) patients, who tend to have abdominal fat deposition, but with normal or mildly overweight epidemiologic features, our center initially had treated T2DM with body mass index (BMI)<35 kg/m² by performing laparoscopic Roux-en-Y gastrojejunostomy since 2008. This procedure is successful in treating abnormal glucose metabolism but not in improving abdominal visceral obesity. However, since 2011, laparoscopic Roux-Y gastric bypass (LRYGB) with a small stomach pouch has been performed at our center, with prominent resolution of abdominal visceral obesity and lower incidences of postoperative complications. The purpose of the present study was to formally compare these different procedures. From 2011 to 2013, 60 patients who met the NIH criteria were recruited and randomly assigned to undergo either laparoscopic Roux-en-Y gastrojejunostomy (n = 30) or LRYGB with a small stomach pouch (n = 30). All of the patients were followed for 12 months, and pre- and postoperative changes in BMI, waist circumference, fasting plasma glucose (FPG), postprandial plasma glucose (PBG), glycated hemoglobin (HbA1c), homoeostatic model assessment (HOMA-IR), the body fat rate and major complications were recorded. Both procedures were successful in reducing HbA1c, FPG, and PBG levels and HOMA-IR scores. However, LRYGB with a small stomach pouch resulted in a greater reduction in FPG, PBG, and HbA1c levels, and HOMA-IR scores compared with Roux-en-Y gastrojejunostomy. In addition, the reductions in BMI, body fat content, waist circumference, and the incidence of postoperative marginal ulcers in the small-stomach-pouch LRYGB were significant. Both procedures are effective treatments for T2DM patients with BMI<35 kg/m². However, the advantages of resolved abnormal glucose metabolism and abdominal visceral obesity and decreased incidences of surgical complications are more obvious for LRYGB with a small gastric

Background: Localized alveolar ridge defect may create physiological and pathological problems. Developments in surgical techniques have made it simpler to change the configuration of a ridge to create a more aesthetic and more easily cleansable shape. The purpose of this study was to compare the efficacy of alveolar ridge augmentation using a subepithelial connective tissue graft in pouch and modified connective tissue graft technique. Materials and Methods: In this randomized, double blind, parallel and prospective study, 40 non-smoker individuals with 40 class III alveolar ridge defects in maxillary anterior were randomly divided in two groups. Group I received modified connective tissue graft, while group II were treated with subepithelial connective tissue graft in pouch technique. The defect size was measured in its horizontal and vertical dimension by utilizing a periodontal probe in a stone cast at base line, after 3 months, and 6 months post surgically. Analysis of variance and Bonferroni post-hoc test were used for statistical analysis. A two-tailed P < 0.05 was considered to be statistically significant. Results: Mean values in horizontal width after 6 months were 4.70 ± 0.87 mm, and 4.05 ± 0.89 mm for group I and II, respectively. Regarding vertical heights, obtained mean values were 4.75 ± 0.97 mm and 3.70 ± 0.92 mm for group I and group II, respectively. Conclusion: Within the limitations of this study, connective tissue graft proposed significantly more improvement as compare to connective tissue graft in pouch. PMID:26759591

In experimental aneurysm models, long-term patency without spontaneous thrombosis is the most important precondition for analyses of embolization devices. We recently reported the feasibility of creating complex venous pouch bifurcation aneurysms in the rabbit with low morbidity, low mortality, and high short-term aneurysm patency. In order to further evaluate our model, we examined the long-term patency rate. Various sizes of complex bilobular, bisaccular, and broad-neck venous pouch aneurysms were surgically formed at an artificially created bifurcation of both common carotid arteries in 17 rabbits. Early aggressive anticoagulation was continued for 1 month. The rabbits were followed up using contrast-enhanced three-dimensional 1.5-T magnetic resonance angiography (CE-3D-MRA) at 1 month and up to 1 year after creation of the bifurcation. At 1-month follow-up, all but one of the created aneurysms and all parent vessels proved to be patent. Three animals (18%) were lost during follow-up for reasons unrelated to aneurysm surgery. At 1-year follow-up, one animal showed partial and one complete spontaneous aneurysm thrombosis (aneurysm patency rate: 86%). Six out of 42 parent vessels were occluded at that time (vessel patency rate: 86%). Complex bilobular, bisaccular, and broad-neck microsurgical aneurysm formation in the rabbit bifurcation model demonstrates a high long-term patency rate but is complicated by high rates of unrelated procedural mortality and morbidity. There is no need for prolonged (>4 weeks) anticoagulation to achieve good long-term patency in complex venous pouch bifurcation aneurysms.

Congenital heart defects and extracardiac malformations.

To review the association between congenital heart defects and extracardiac malformations. Scientific articles were searched in the Medline, Lilacs, and SciELO databases, using the descriptors "congenital heart disease," "congenital heart defects," "congenital cardiac malformations," "extracardiac defects," and "extracardiac malformations." All case series that specifically explored the association between congenital heart defects and extracardiac malformations were included. Congenital heart diseases are responsible for about 40% of birth defects, being one of the most common and severe malformations. Extracardiac malformations are observed in 7 to 50% of the patients with congenital heart disease, bringing a greater risk of comorbidity and mortality and increasing the risks related to heart surgery. Different studies have attempted to assess the presence of extracardiac abnormalities in patients with congenital heart disease. Among the changes described, those of the urinary tract are more often reported. However, no study has evaluated all patients in the same way. Extracardiac abnormalities are frequent among patients with congenital heart disease, and patients with these alterations may present an increased risk of morbimortality. Therefore, some authors have been discussing the importance and cost-effectiveness of screening these children for other malformations by complementary exams.

Oesophageal atresia with trachea-oesophageal fistula is a rare foregut malformation that requires surgery soon after birth. Prenatal ultrasound diagnosis is based on the presence of polyhydramnios, a small or non-visible fetal stomach and the blind ending oesophagus, called the upper pouch (1). Neonates present with salivation, coughing, choking and attacks of cyanosis. A diagnosis of oesophageal atresia is confirmed by inserting a nasogastric tube and a thoraco-abdominal X-ray.

Congenital amusias.

In contrast to the sophisticated music processing reported in the general population, individuals with congenital amusia show deficits in music perception and production. Congenital amusia occurs without brain damage, sensory or cognitive deficits, and has been suggested as a lifelong deficit with genetic origin. Even though recognized for a long time, this disorder has been systematically studied only relatively recently for its behavioral and neural correlates. The currently most investigated hypothesis about the underlying deficits concerns the pitch dimension, notably with impaired pitch discrimination and memory. Anatomic and functional investigations of pitch processing revealed that the amusic brain presents abnormalities in the auditory and inferior frontal cortices, associated with decreased connectivity between these structures. The deficit also impairs processing of pitch in speech material and processing of the time dimension in music for some of the amusic individuals, but does not seem to affect spatial processing. Some studies suggest at least partial dissociation in the disorder between perception and production. Recent studies revealed spared implicit pitch perception in congenital amusia, supporting the power of implicit cognition in the music domain. Current challenges consist in defining different subtypes of congenital amusia as well as developing rehabilitation programs for this "musical handicap." © 2015 Elsevier B.V. All rights reserved.

Our aim was to assess the overall burden of congenital syndromes and non-cardiac comorbidities among adults with congenital heart disease and to assess their impact on circumstances of living and outcomes. Within a cohort of 1725 adults with congenital heart defects (65% defects of moderate or great complexity) followed at a single tertiary care center, congenital syndromes and comorbidities were identified by chart review. Their association with arrhythmias, circumstances of living and survival was analyzed. Within the study cohort, 232 patients (13%) had a genetic syndrome, 51% at least one comorbidity and 23% ≥2 comorbidities. Most prevalent comorbidities were systemic arterial hypertension (11%), thyroid dysfunction (9%), psychiatric disorders (9%), neurologic disorders (7%), chronic lung disease (7%), and previous stroke (6%). In contrast to higher congenital heart defect complexity, the presence of comorbidities had no impact on living circumstances but patients with comorbidities were less likely to work full-time. Atrial arrhythmias were more common among patients with moderate/great disease complexity and those with comorbidities but were less common among patients with congenital syndromes (p<0.01 for all comparisons). Patients with ≥2 comorbidities had lower survival estimates compared to those with ≤1 comorbidity (p=0.013). Congenital syndromes and comorbidities are highly prevalent in adults with congenital heart disease followed at specialist centers and add to the overall complexity of care. The presence of these additional factors has an impact on living circumstances, is associated with arrhythmias and needs to be further explored as prognostic markers. Copyright © 2017 Elsevier B.V.

Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the current gold standard in the surgical treatment of ulcerative colitis (UC) refractory to medical management. A procedure of significant magnitude carries its own risks including anastomotic failure, pelvic sepsis and a low rate of neoplastic degeneration overtime. Recent studies have shown that total colectomy with ileorectal anastomosis (IRA) has been associated with good long-term functional results in a selected group of UC patients amenable to undergo a strict surveillance for the relatively high risk of cancer in the rectum. This manuscript will review and compare the most recent literature on IRA and IPAA as it pertains to postoperative morbidity and mortality, failure rates, functional outcomes and cancer risk.

Congenital cholesteatoma may be expected in abnormally developed ear, it may cause bony erosion of the middle ear cleft and extend to the infratemporal fossa. We present the first case of congenital cholesteatoma of the infratemporal fossa in a patient with congenital aural atresia that has been complicated with acute mastoiditis. A sixteen year old Egyptian male patient presented with congenital cholesteatoma of the infratemporal fossa with congenital aural atresia complicated with acute mastoiditis. Two weeks earlier, the patient suffered pain necessitating hospital admission, magnetic resonance imaging revealed a soft tissue mass in the right infratemporal fossa. On presentation to our institute, Computerized tomography was done as a routine, it proved the diagnosis of mastoiditis, pure tone audiometry showed an air-bone gap of 60 dB. Cortical mastoidectomy was done for treatment of mastoiditis, removal of congenital cholesteatoma was carried out with reconstruction of external auditory canal. Follow-up of the patient for 2 years and 3 months showed a patent, infection free external auditory canal with an air-bone gap has been reduced to 35db. One year after the operation; MRI was done and it showed no residual or recurrent cholesteatoma. Congenital cholesteatoma of the infratemporal fossa in cases of congenital aural atresia can be managed safely even if it was associated with mastoiditis. It is an original case report of interest to the speciality of otolaryngology.

Giant colonic volvulus due to colonic pseudo-obstruction

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

Congenital Malaria in China

Abstract Background Congenital malaria, in which infants are directly infected with malaria parasites from their mother prior to or during birth, is a potentially life-threatening condition that occurs at relatively low rates in malaria-endemic regions. It is recognized as a serious problem in Plasmodium falciparum–endemic sub-Saharan Africa, where recent data suggests that it is more common than previously believed. In such regions where malaria transmission is high, neonates may be protected from disease caused by congenital malaria through the transfer of maternal antibodies against the parasite. However, in low P. vivax–endemic regions, immunity to vivax malaria is low; thus, there is the likelihood that congenital vivax malaria poses a more significant threat to newborn health. Malaria had previously been a major parasitic disease in China, and congenital malaria case reports in Chinese offer valuable information for understanding the risks posed by congenital malaria to neonatal health. As most of the literature documenting congenital malaria cases in China are written in Chinese and therefore are not easily accessible to the global malaria research community, we have undertaken an extensive review of the Chinese literature on this subject. Methods/Principal Findings Here, we reviewed congenital malaria cases from three major searchable Chinese journal databases, concentrating on data from 1915 through 2011. Following extensive screening, a total of 104 cases of congenital malaria were identified. These cases were distributed mainly in the eastern, central, and southern regions of China, as well as in the low-lying region of southwest China. The dominant species was P. vivax (92.50%), reflecting the malaria parasite species distribution in China. The leading clinical presentation was fever, and other clinical presentations were anaemia, jaundice, paleness, diarrhoea, vomiting, and general weakness. With the exception of two cases, all patients were cured

Ultrasound examinations during pregnancy are routine procedures used to detect fetal congenital malformations. Ultrasound monitoring of sigmoid colon mesenterial development could be useful for early detection of subjects at risk of sigmoid colon volvulus. The aim of our paper was to assess the sigmoid colon length, and sigmoid colon mesentery width and height in the late fetal period, and, using the results, to estimate the surface area of the mesocolon (in mm 2 ) in living fetuses. Moreover, we attempted to repeat some of these measurements in living fetuses using ultrasound imaging. The study was carried out on 209 formalin fixed human fetuses (100 female and 109 male) aged from 4th to 7th gestational months (102-203 days), with a crown-rump length of 132-342mm. The length of the sigmoid colon, as well as the height and width of its mesentery were measured. The surface area of the mesocolon was estimated. Correction for formalin induced shrinkage was applied. Pilot ultrasound examinations of live fetuses were performed. Mean values of sigmoid colon length, mesenteric width and height (formalin fixed fetuses) for respective gestational ages were: month 4: 21.46±6.7mm, 6.80±2.1mm, 5.5±1.49mm; month 5: 27.32±1.2mm, 7.62±2.01mm, 7.33±2.17mm; month 6: 47.56±9.57mm, 11.68±3.8mm, 10.3±3.05mm; month 7: 56.92±17.48mm. 15.32±8 mm, 12.81±3.16mm. The surface area ranges of the sigmoid colon mesentery found for respective gestational months (intrauterine fetuses) were as follows: month 4: 33.24-51.95mm 2 ; month 5: 49.63-77.6mm 2 ; month 6: 106.89-167.15mm 2 and month 7: 145.69-272.53mm 2 . The surface area of the sigmoid colon mesentery can be used as a simple parameter applied in fetal ultrasonographic evaluation. The development of the sigmoid colon accelerates in the 6th gestational month, and decelerates in the 7th gestational month. The sigmoid colon mesentery width was larger than its height between the 4th and 7th gestational months. Copyright © 2017

The objective of this study was to determine the reproducibility of rat results. Over an 18-month period 11,869 samples were examined by the rats. Intra-rater reliability was assessed through Yule's Q. Inter-rater reliability was assessed with Krippendorff's alpha. Intra-rater reliability was high, with a mean Yule's Q of 0.9. Inter-rater agreement was fair, with Krippendorf's alpha ranging from 0.15 to 0.45. Both Intra- and Inter-rater reliability was independent of the sex of the animals, but they were positively correlated with age. Both intra- and inter-rater agreement was lowest for samples designated as smear-negative by the clinics. Overall, the reproducibility of tuberculosis detection rat results was fair and diagnostic results were therefore independent of the rats used.

Hypothalamo-pituitary hormone insufficiency associated with cleft lip and palate.

Two male patients with congenital cleft lip and palate first seen at ages 10.2 and 21.5 years presented with typical signs of hypothalamic-interior pituitary hormone deficiencies. They were found to lack GH, LH, and FSH and to be partially deficient in TSH and ACTH. Several congenital defects may explain this rare syndrome affecting midline structures in the proximity of the maldeveloped palate, including Rathke's pouch, which migrates distally to develop into the anterior pituitary.

2018-03-01

Congenital portosystemic venous shunts are rare developmental anomalies resulting in diversion of portal flow to the systemic circulation and have been divided into extra- and intrahepatic shunts. They occur during liver and systemic venous vascular embryogenesis and are associated with other congenital abnormalities. They carry a higher risk of benign and malignant liver tumors and, if left untreated, can result in significant medical complications including systemic encephalopathy and pulmonary hypertension. This article reviews the various types of congenital portosystemic shunts and their anatomy, pathogenesis, symptomatology, and timing and options of treatment. What is Known: • The natural history and basic management of this rare congenital anomaly are presented. What is New: • This paper is a comprehensive review; highlights important topics in pathogenesis, clinical symptomatology, and treatment options; and proposes an algorithm in the management of congenital portosystemic shunt disease in order to provide a clear idea to a pediatrician. An effort has been made to emphasize the indications for treatment in the children population and link to the adult group by discussing the consequences of lack of treatment or delayed diagnosis.

Congenital heart disease in adults (adult congenital heart disease) is a growing burden for healthcare systems. While infant mortality due to congenital heart disease in the last four decades decreased by almost 3-fold, adult congenital heart disease prevalence increased by more than 2-fold in United States. Adult congenital heart disease prevalence is expected to increase steadily until 2050 in projections. Adult congenital heart disease is a multifaceted problem with many dimensions. This manuscript aims to provide an overview of the common adult congenital heart diseases and summarize important points in management of these diseases with possible problems and complications that the patients and the physicians face.

Laparoscopic surgery for colon cancer with intestinal malrotation in adults: Two case reports and review of literatures in Japan.

Intestinal malrotation is a congenital anomaly, and its occurrence in adults is rare. Colon cancer with intestinal malrotation is far more rare. We herein report two cases of colon cancer with intestinal malrotation treated with laparoscopic surgery and reviewed the literatures in Japan. Case 1 involved a 78-year-old man. Abdominal enhanced computed tomography (CT) showed that the tumor was located in the sigmoid colon. Intraoperatively, the cecum and ascending colon were located along the midline and the small intestine occupied the right side of the abdomen. The tumor was located in the cecum, and the patient was diagnosed with cecal cancer with intestinal malrotation. We performed laparoscopy-assisted ileocecal resection. Case 2 involved a 81-year-old man. Colonoscopy revealed a laterally spreading tumor in the cecum. Intraoperatively, the position of the small intestine and the ascending colon was similar to case 1, and Ladd's band was found in front of the duodenum. Thus, we diagnosed the patient with a laterally spreading cecal tumor with intestinal malrotation and performed laparoscopy-assisted ileocecal resection. A review of the literature revealed 49 cases of colon cancer with intestinal malrotation and laparoscopic surgery performed at 30.6%. If laparoscopic mesenteric excision for colon cancer with intestinal malrotation is unsafe because of the abnormalities of the artery, mesenteric excision should be performed outside the body. If the intestinal malrotation is diagnosed preoperatively, 3D-CT angiography should be used to reveal the vascular anatomic anomalies for safe performance of laparoscopic surgery.

Laparoscopic ileal pouch-anal anastomosis (IPAA) is associated with recovery benefits when compared with open IPAA. There is limited data on long-term quality of life and functional outcomes, which this study aimed to assess. An IRB-approved, prospectively maintained database was queried to identify patients undergoing laparoscopic IPAA (L), case-matched with open IPAA (O) based on age ± 5 years, gender, body mass index (BMI) ± 5 kg/m 2 , diagnosis, date of surgery ± 3 years, stapled/handsewn anastomosis, omission of diverting loop ileostomy and length of follow-up ± 3 years. We assessed functional results, dietary, social, work, sexual restrictions and the Cleveland Clinic global quality of life score (CGQoL) at 1, 2, 3, 4, 5 and 10 years postoperatively. Functional outcomes were assessed based on number of stools (day/night) and seepage protection use (day/night). Variables were evaluated with Kaplan-Meier survival curves, uni- and multivariable analyses. Out of 4595 IPAAs, 529 patients underwent L, of whom 404 patients were well matched 1:1 to an equivalent number of O based on all criteria. Median follow-ups were 2 (0.5-17.8) versus 2.4 (0.5-22.2) years in L versus O, respectively (p = 0.18). L was associated with significantly decreased number of stools at night and less frequent pad usage at 1 year, both during the day and at night. Functional outcomes became similar during further follow-up. L was also associated with improved overall CGQoL, and energy scores at 1 year postoperatively, and decreased social restrictions for 1-2 years. There were no significant differences in quality of health, dietary, work or sexual restrictions. Laparoscopy was not associated with increased risk of pouch failure (p = 0.07) or significantly different causes of pouch failure when compared to O. Laparoscopic and open IPAA are associated with equivalent long-term functional outcomes, quality of life and pouch survival rates. Laparoscopic

Congenital Morgagni's hernia (CMH) is rare and represents less than 5% of all congenital diaphragmatic hernias. This is a national review of our experience with CMH outlining clinical presentation, methods of diagnosis, associated anomalies, treatment, and outcome. The medical records of all patients with the diagnosis of CMH treated at four pediatric surgery units in Saudi Arabia were retrospectively reviewed for age at diagnosis, sex, presenting symptoms, associated anomalies, diagnosis, operative findings, treatment, and outcome. During a 20-year period (January 1990-December 2010), 53 infants and children with CMH were treated. There were 38 males and 15 females. Their age at diagnosis ranged from 1 month to 9 years (mean 22.2 months). Forty-three (81%) presented with recurrent chest infection. Twenty-two (44.5%) had right CMH, 15 (28.3%) had left-sided hernia and 16 (30.2%) had bilateral hernia. In 7, the diagnosis of bilaterality was made at the time of surgery. Associated anomalies were seen in 38 (71.7%). Twenty-one (39.6%) had congenital heart disease, 8 (15%) had malrotation, and 15 (28.3%) had Down syndrome. All were operated on. Twenty-nine (54.7%) underwent repair via an open approach. The remaining 24 (45.3%) underwent repair using minimal invasive surgery, laparoscopic-assisted hernia repair (19 patients) or totally laparoscopic approach (5 patients). At the time of surgery, the hernia sac content included the colon in 33 (62.3%), part of the left lobe of the liver in 13 (24.5%), the small intestines in 11 (20.75%), the omentum in 5 (9.4%), and the stomach in 4 (7.5%). In 12 (22.6%), the hernia sac was empty. When compared to the open repair, the laparoscopic-assisted approach was associated with a shorter operative time, an earlier commencement of feeds, less requirement for postoperative analgesia, a shorter hospital stay, and better cosmetic appearance. There was no mortality. On follow-up, 2 (7%) of the open surgical group developed recurrence

A fourth branchial pouch remnant is well known as a pyriform sinus fistula. However, there has been no report of a fistula composed of the complete remnant of the fourth branchial apparatus. We experienced patients with a congenital lower neck cutaneous fistula which was thought to be the skin-side remnant of the fourth branchial cleft. Seven children were referred to our hospital from 2009 to 2015 for the treatment of a cutaneous fistula situated near the sternoclavicular joint. All of them were surgically resected and their pathological characteristics were examined. Clinical charts were retrospectively reviewed. In six cases, the left side was affected. All cutaneous fistulas had a small skin orifice near the sternoclavicular joint and they were situated at the anterior edge of the sternocleidomastoid muscle. Abscess formation was seen in four cases. Surgical resection was performed at the age of 6 months to 9 years. These fistulas ran deep into the subcutaneous tissue and had a blind end. Pathological examination showed that the epithelial layer was mainly composed of a stratified squamous epithelium. In two cases the epithelium was composed of ciliated columnar epithelium. Recurrence has not been observed in any of the cases. The seven cases had a common clinical feature and were a definite clinical entity. Judging from the characteristics of our cases and the previous literature, we concluded that this lower neck cutaneous fistula was most likely a congenital skin-side remnant of the fourth branchial cleft.

Oral cancer has becomes the most prominent male cancer disease due to the local betel nut chewing habit combing with smoking and alcohol-drinking lifestyle. In order to minimize the systemic phototoxic effect of 5-aminolevulinic acid (ALA), this study was designed to use a topical ALA-mediated PDT for treatment of DMBA-induced hamster buccal pouch cancerous lesions. DMBA was applied to one of the buccal pouches of hamsters thrice a week for 8 to 10 weeks. Precancerous lesions were induced and proven by histological examination. These DMBA-induced cancerous lesions were used for testing the efficacy of topical ALA -mediated PDT. We found that ALA reached its peak level in cancerous lesions about 2.5 hrs after topical application of ALA gel. The precancerous lesions in hamsters were then treated with topical ALA -mediated PDT with light exposure dose of 75 and 100 J/cm2 using LED 635 nm Wonderlight device. It is suggesting that optimization of the given light dose is critical to the success of PDT results.

In Taiwan, oral cancer has become a prominent cancer because of its highest annual increase rate among all cancer diseases. Betel quid chewing habit is a major risk factor for oral precancerous and cancerous lesions and there are more than two million people who have this habit in Taiwan. Our previous studies showed that chlorophyll-pheophytin derivative (CPD)-mediated PDT is very effective for killing of SCC-4 cell lines in vitro. In order to decrease the systemic phototoxic effect of CPD, this study was designed to use a topical CPD-mediated PDT for treatment of DMBA-induced hamster buccal pouch precancerous lesions. DMBA was applied to one of the buccal pouches of hamsters thrice a week for 8 to 10 weeks. Precancerous lesions of moderate to severe dysplasia were induced and proven by histological examination. These induced precancerous lesions were used for testing the efficacy of topical CPD-mediated PDT. Before PDT, fluorescence spectroscopy was used to determine when CPD reached its peak level in the lesional epithelial cells after topical application of CPD gel. We found that CPD reached its peak level in precancerous lesions about 1 hour (range, 0 to 30 hours) after topical application of CPD gel. The precancerous lesions in hamsters were then treated with topical CPD-mediated PDT (fluence rate: 200 mW/cm2; light exposure dose 100 J/cm2) using the portable WonderLight LED 635 nm fiber-guided light device once or twice a week. Visual and histological examination demonstrated that topical CPD-mediated PDT was partially effective treatment modality for DMBA-induced hamster buccal pouch precancerous lesions.

Early detection of congenital syphilis.

Late congenital syphilis is a very rare clinical entity, and its early diagnosis and treatment is essential. Dental findings often provide valuable evidence for the diagnosis of late congenital syphilis. It occurs due to the transmission of the disease from an infected mother to her fetus through placenta. This long forgotten disease continues to effect pregnant women resulting in perinatal morbidity and mortality. Congenital syphilis is a preventable disease, and its presence reflects a failure of prenatal care delivery system, as well as syphilis control programs. We are reporting a case of late congenital syphilis with only Hutchinson's teeth.

Inhibitory effect of the Ruscus extract and of the flavonoid hesperidine methylchalcone on increased microvascular permeability induced by various agents in the hamster cheek pouch.

The Ruscus extract and the flavonoid hesperidine methylchalcone (HMC) are used in treatment of venous insufficiency. In the present study, we used the hamster cheek pouch preparation and investigated the effects of these substances on increased microvascular permeability induced by bradykinin, histamine, and leukotriene B4 (LTB4) applied topically. Experiments were performed on male hamsters; 30 min after completion of the cheek pouch preparation, fluorescein-labeled dextran [molecular weight (mol wt) 150,000] was given intravenously (i.v.). Bradykinin, histamine, and LTB4 increased the number of fluorescent vascular leakage sites from postcapillary venules, evidence for an increase in macromolecular permeability, which was quantified in ultraviolet (UV)-light microscope as the number of leaky sites in the prepared area. Ruscus extract and HMC, given i.v., significantly inhibited the macromolecular permeability-increasing effect of bradykinin, LTB4, and histamine. Ruscus extract, applied topically, dose dependently inhibited the macromolecular permeability-increasing effect of histamine. Our results show that Ruscus extract and HMC have a protective effect against leakage of FITC-dextran in the cheek pouch after administration of various permeability-increasing substances, which further supports data previously reported on patients with venous insufficiency.

To evaluate the outcomes of laparoscope-assisted peritoneal vaginoplasty for the treatment of congenital vaginal atresia. A retrospective study enrolled patients diagnosed with congenital vaginal atresia who were treated with one of two different laparoscope-assisted peritoneal vaginoplasty techniques (named Luohu-one and Luohu-two) between October 31, 2001 and December 31, 2014. Operative time, intraoperative bleeding volume, surgical difficulty, complications, and post-procedure sexual satisfaction were reported. Data were collected for 620 patients. The Luohu-one procedure was used in the treatment of 145 patients, while 475 patients were treated with the Luohu-two procedure. In 5 (0.8%) patients, it was necessary to perform a sigmoid colon vaginoplasty. During surgery, 16 patients experienced a rectal injury, among whom, 9 patients experienced a rectal-vaginal fistula. Follow-up data extending to 7years were available for 285 patients. Of these 285 patients, 231 agreed to report details of their sexual experiences. In total, 222 (96.1%) patients reported being very satisfied with their vaginal conditions and sex life. The Luohu-two procedure demonstrated shorter operative and recovery time, and reduced intraoperative bleeding. However, both procedures demonstrated satisfactory results. Laparoscope-assisted peritoneal vaginoplasty demonstrated good safety and effectiveness in the treatment of patients with congenital vaginal atresia.

Scoglio, Daniele; Ahmed Ali, Usama; Fichera, Alessandro

2014-01-01

Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the current gold standard in the surgical treatment of ulcerative colitis (UC) refractory to medical management. A procedure of significant magnitude carries its own risks including anastomotic failure, pelvic sepsis and a low rate of neoplastic degeneration overtime. Recent studies have shown that total colectomy with ileorectal anastomosis (IRA) has been associated with good long-term functional results in a selected group of UC patients amenable to undergo a strict surveillance for the relatively high risk of cancer in the rectum. This manuscript will review and compare the most recent literature on IRA and IPAA as it pertains to postoperative morbidity and mortality, failure rates, functional outcomes and cancer risk.

We propose to demonstrate that it is possible to implement a valid (diagnostic sensitivity for major cardiac malformations 90%), and universal (applied to over 90% of pregnant women), prenatal screening method for congenital heart defects. Prospective study. A total of 12478 pregnant women were evaluated between January 2008 and December 2010. Congenital heart diseases were screened using fetal extended basic echocardiography (cardiac ultrasound). The prevalence of birth defects in general and congenital heart disease was 2.5% (2.2-2.7%) and 0.9% (0.7-1%) respectively. Congenital heart disease had a higher rate of association with other structural abnormalities with 11.5% (5.6-17.4%), 21% for major congenital heart disease (9.9-32%), and chromosomal abnormalities of 15.9% (9.1-22.7%), with 32.6% for major congenital heart disease (19.8-45.3%). A fetal cardiac ultrasound assessment was performed on 99.2% of pregnant women. The fetal echocardiography is useful for the diagnosis of congenital heart disease in general, and major congenital heart disease, with a sensitivity of 42.8% (33.5-52.5%) and 90.4% (78.9-96.8%), respectively, and a specificity for both of 99.9% (99.8-99.9%). It is possible to perform a valid prenatal and universal screening of major congenital heart disease. Copyright © 2012 Asociación Española de Pediatría. Published by Elsevier Espana.

The Congenital Heart Surgeons' Society is a group of over 100 pediatric heart surgeons representing 72 institutions that specialize in the treatment of patients with congenital heart defects. The Society began in 1972 and incorporated as a not-for-profit charitable organization in 2004. It has become the face and voice of congenital heart surgery in North America. In 1985, the Society established a data center for multicenter clinical research studies to encourage congenital heart professionals to participate in improving outcomes for our patients. The goals of the Congenital Heart Surgeons' Society are to stimulate the study of congenital cardiac physiology, pathology, and management options which are instantiated in data collection, multi-institutional studies, and scientific meetings. Honest and open discussion of problems with possible solutions to the challenges facing congenital heart professionals have been the strength of the Congenital Heart Surgeons' Society. It is imperative for the growth of an organization to know from where it came in order to know to where it is going. The purpose of this article is to review the history of the Congenital Heart Surgeons' Society. © The Author(s) 2015.

Rapid promotion and progression of fibrovascular polyps by inflammation and/or hyperplasia in hamster check pouch: implications for carcinogenesis assay.

PubMed

McGaughey, C; Jensen, J L

1983-03-01

Tumor initiation by topical application of 7,12-dimethylbenz[a]anthracene (DMBA) in dimethyl sulfoxide (DMSO) followed by topical application of retinyl acetate (RA), ethylphenylpropiolate, or acetic acid in DMSO at inflammatory and hyperplasiogenic dose regimens caused the rapid promotion of fibrovascular polyps with dysplastic epithelium in hamster cheek pouch. Such lesions did not occur in control animals initiated with DMBA followed by application of DMSO only, where inflammation was also minimal. At the dose regimen employed, RA caused obvious cytotoxicity and tissue destruction. With EPP and AA, there was no histological evidence of tissue destruction. At dose regimens resulting in minimal inflammation and no apparent cytotoxicity, RA promoted almost no polyps, but a higher yield of other tumor types. Thus, inflammation and/or hyperplasia apparently exerted a strong polyp-promoting and progressive influence. This and other differences between the tumorigenic responses of hamster-pouch mucosa and mouse skin suggest that the former supplement the latter in carcinogenic risk assessment.

A retrospective clinical review. To review the use of modern instrumentation of the spine for congenital spinal deformities. Spinal instrumentation has evolved since the advent of the Harrington rod. There is a paucity of literature, which discusses the use of modern spinal instrumentation in congenital spine deformity cases. This review focuses on modern instrumentation techniques for congenital scoliosis and kyphosis. A systematic review was performed of the literature to discuss spinal implant use for congenital deformities. Spinal instrumentation may be safely and effectively used in cases of congenital spinal deformity. Spinal surgeons taking care of children with congenital spine deformities need to be trained in all aspects of modern spinal instrumentation.

To determine the frequency of congenital heart defects (CHD) in children with gastrointestinal malformations (GISM) and mortality rates in patients with GISM. Two hundred and forty two consecutive children patients with GISM followed up in Pediatric Surgery Clinics of our hospital were examined for cardiovascular anomaly by the Department of Pediatric Cardiology, and the CHD incidence was investigated by examining the records of the patients retrospectively. Chi-square test was used for the statistical analysis of data. Two hundred and forty two patients with gastrointestinal system malformations were included in the study. Of 242 patients, 135 (55.8%) were male and 107 (44.2%) were female, and their age range was 0-15 years. The most frequent GISM were anorectal malformations (43.2%), atresia involving stomach, ileum or colon (21%) and esophageal atresia/tracheoesophageal fistula (18.3%). Congenital heart defects were observed in 28.5% of the participants. The most frequent defects were as follows; atrial septal defect (31 patients, 44.9%) a, ventricular septal defect (17 patients, 24.6%) and patent ductus arteriosus (5 patients, 7.2%). There was no significant difference (p>0.05) in mortality rate in patients with CHD (16.7%) and without CHD (13.3%) undergoing operations for GISM. We would like to emphasize the importance of the earliest possible cardiological evaluation of all patients with gastrointestinal system malformations.

Altered cytokeratin expression during chemoprevention of experimental hamster buccal pouch carcinogenesis by garlic.

2002-03-01

Cytokeratins (also known as keratins (K)) are members of the family of intermediate filaments and form major components of the mammalian epithelial cell cytoskeleton. Cytokeratins have emerged as reliable cellular markers of oral cancer development and chemoprevention because of their abundance, stability and high antigenicity. We investigated the effect of aqueous garlic extract on cytokeratin expression during 7,12-dimethylbenz[a]anthracene (DMBA)-induced hamster buccal pouch (HBP) carcinogenesis. Hamsters were divided into four groups of six animals. Animals in group 1 were painted with a 0.5% solution of DMBA in liquid paraffin, on the right buccal pouches, three times a week for 14 weeks. Group 2 animals were painted with DMBA as in group 1 and also received 250 mg/kg body weight aqueous garlic extract orally on alternate days to the DMBA application. Group 3 animals received garlic extract only, as in group 2. Group 4 animals received neither DMBA nor garlic extract and served as the control. The hamsters were killed after an experimental period of 14 weeks. Cytokeratin expression was studied using human monoclonal antibodies AE1 and AE3, which react with type I and II keratins. In DMBA-induced squamous cell carcinomas, decreased expression of high molecular weight keratins was observed. Administration of garlic extract to animals painted with DMBA suppressed HBP carcinomas and restored normal cytokeratin expression. The results of the present study suggest that inhibition of HBP carcinogenesis by garlic may be due to its regulatory effects on differentiation, tumour invasiveness, migratory and metastatic potential. We suggest that one of the mechanisms of tumour inhibition by garlic is an influence on cellular differentiation.

Congenital dyserythropoietic anemia (CDA) is a heterogeneous group of rare congenital disorders characterized by ineffective erythropoiesis and dysplastic changes in erythroblasts. Diagnosis of CDA is based primarily on the morphology of bone marrow erythroblasts; however, genetic tests have recently become more important. Here, we performed genetic analysis of 10 Japanese patients who had been diagnosed with CDA based on laboratory findings and morphological characteristics. We examined 10 CDA patients via central review of bone marrow morphology and genetic analysis for congenital bone marrow failure syndromes. Sanger sequencing for CDAN1, SEC23B, and KLF1 was performed for all patients. We performed whole-exome sequencing in patients without mutation in these genes. Three patients carried pathogenic CDAN1 mutations, whereas no SEC23B mutations were identified in our cohort. WES unexpectedly identified gene mutations known to cause congenital hemolytic anemia in two patients: canonical G6PD p.Val394Leu mutation and SPTA1 p.Arg28His mutation. Comprehensive genetic analysis is warranted for more effective diagnosis of patients with suspected CDA.

AIM To explore the relationship between colonic secretory function and colonic motility. METHODS Using a rat model chronically implanted with intracerebroventricular (ICV) and cecal catheters, we validated the correlation between colonic secretion and colonic motor functions, as well as the role of ICV injection volume. RESULTS Compared to saline controls (5 μL/rat), ICV acyl ghrelin at 1 nmol/5 μL enhanced the total fecal weight, accelerated the colonic transit time, and increased the fecal pellet output during the first hour post-injection, while ICV des-acyl ghrelin at 1 nmol/5 μL only accelerated the colonic transit time. These stimulatory effects on colonic motility and/or secretion from acyl ghrelin and des-acyl ghrelin disappeared when the ICV injection volume increased to 10 μL compared with saline controls (10 μL/rat). Additionally, the ICV injection of 10 μL of saline significantly shortened the colonic transit time compared with the ICV injection of 5 μL of saline. The total fecal weight during the first hour post-injection correlated with the colonic transit time and fecal pellet output after the ICV injection of acyl ghrelin (1 nmol/5 μL), whereas the total fecal weight during the first hour post-injection correlated with the fecal pellet output but not the colonic transit time after the ICV injection of des-acyl ghrelin (1 nmol/5 μL). CONCLUSION Colonic secretion does not always correlate with colonic motility in response to different colonic stimulations. Acyl ghrelin stimulates colonic secretion. PMID:28028362

Clinicians working in the field of congenital and paediatric cardiology have long felt the need for a common diagnostic and therapeutic nomenclature and coding system with which to classify patients of all ages with congenital and acquired cardiac disease. A cohesive and comprehensive system of nomenclature, suitable for setting a global standard for multicentric analysis of outcomes and stratification of risk, has only recently emerged, namely, The International Paediatric and Congenital Cardiac Code. This review, will give an historical perspective on the development of systems of nomenclature in general, and specifically with respect to the diagnosis and treatment of patients with paediatric and congenital cardiac disease. Finally, current and future efforts to merge such systems into the paperless environment of the electronic health or patient record on a global scale are briefly explored. On October 6, 2000, The International Nomenclature Committee for Pediatric and Congenital Heart Disease was established. In January, 2005, the International Nomenclature Committee was constituted in Canada as The International Society for Nomenclature of Paediatric and Congenital Heart Disease. This International Society now has three working groups. The Nomenclature Working Group developed The International Paediatric and Congenital Cardiac Code and will continue to maintain, expand, update, and preserve this International Code. It will also provide ready access to the International Code for the global paediatric and congenital cardiology and cardiac surgery communities, related disciplines, the healthcare industry, and governmental agencies, both electronically and in published form. The Definitions Working Group will write definitions for the terms in the International Paediatric and Congenital Cardiac Code, building on the previously published definitions from the Nomenclature Working Group.

INTRODUCTION. During the last 30 years, the multidisciplinary treatments of colon and uterus neoplasm have yielded an increase in total survival rates, fostering therefore the increase of cases with regional relapse involving the urinary tract. In these cases the iterative surgery can be performed, if no disease secondary to pelvic pain, haemostatic or debulking procedure is present, and must be considered and discussed with the patient, according to his/her general status. MATERIALS AND METHODS. From 1997 to August 2007 we performed altogether 43 pelvic iterative surgeries, with simultaneous urologic surgical procedure because of pelvic tumor relapse in patients with uterus neoplasm and colon and rectal cancer. In 4 cases of anal cancer, the urological procedure were: one radical prostatectomy with continent vesicostomy in the first case, while in the other 3 cases radical pelvectomy with double-barrelled uretero-cutaneostomy. In 23 cases of colon cancer, the urologic procedures were: 9 cases of radical cystectomy with double-barrelled uretero-cutaneostomy, 4 cases of radical cystectomy with uretero-ileo-cutaneostomy according to Bricker- Wallace II procedure, and 9 cases of partial cystectomy with pelvic ureterectomy and ureterocystoneostomy according to Lich-Gregoire technique (7 cases) and Lembo-Boari (2 cases) procedure. In 16 cases of uterus cancer, the urological procedure were: 7 cases of partial cystectomy with pelvic ureterectomy and uretero-cystoneostomy according to Lich-Gregoire procedure; in 3 cases, a radical cystectomy with urinary continent cutaneous diversion according to the Ileal T-pouch procedure; 2 cases of total pelvectomy and double uretero-cutaneostomy, and 4 cases of bilateral uretero-cutaneostomy. RESULTS. No patients died in the perioperative time; early systemic complications were: 2 esophageal candidiasis, 1 case of venous thrombosis. CONCLUSIONS. The iterative pelvic surgery in the case of oncological relapse involving the urinary

Dermatoglyphs in congenital heart disease.

David, T J

1981-01-01

The palmar dermatoglyphs of 800 patients with anatomically proven congenital heart disease were compared with prints from 1000 controls. A review of the previous studies revealed major technical deficiencies, and the present study failed to confirm most of the previously reported positive findings. An overall increase in the incidence of hypothenar patterns was found, probably explaining the previous suggestion of increased atd angle in congenital heart disease. A large number of statistical comparisons inevitably produced a few 'significant' results, most of which were inconsistent in various ways. Two percent of cases were found to have rare epidermal ridge malformation, ridge dissociation. The nature of the relationship between this and congenital heart disease is obscure. Claims that there are diagnostically useful dermatoglyphic changes in congenital heart disease can be disregarded. PMID:7328614

Syphilis is a re-emerging infectious disease in Western Europe. Congenital syphilis is a potentially serious pathology affecting newborns of infected mothers. This disease is easily curable by a simple antibiotic treatment. Because of systematic antenatal screening it should no longer exist in industrialized countries. Nevertheless, we report a case of a six-week-old infant with a delayed diagnosis of congenital syphilis. Physicians, especially gynaecologists, obstetricians and paediatricians, have to be vigilant in order to allow for early diagnosis and appropriate treatment of congenital syphilis.

OBJECTIVE--To estimate the proportion of preventable congenital abnormalities in Hungary. DESIGN--Analysis of available Hungarian data-bases and of the effectiveness of primary, secondary, and tertiary preventive methods. SETTING--Databases of ad hoc epidemiological studies and of the Hungarian congenital abnormality registry. MAIN OUTCOME MEASURES--Prevalence at birth and prevalence after prevention in 73 congenital abnormality types or groups. RESULTS--Preventive methods are available for 51 (70%) of the 73 congenital abnormality types or groups evaluated. The birth prevalence of all congenital abnormalities could be reduced from 65 to 26 per 1000; thus 39 per 1000 (60%) are preventable. Without congenital dislocation of the hip, which is unusually common in Hungary, the preventable proportion of congenital abnormalities is 52%. CONCLUSION--Many congenital abnormalities can be prevented, but as they do not represent a single pathological category there is no single strategy for their prevention.

Topical 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT) is effective for treatment of human oral precancerous lesions. This animal study aimed to assess whether topical methotrexate (MTX) pretreatment could enhance the therapeutic effect of topical ALA-PDT on hamster buccal pouch precancerous lesions. Twenty hamster buccal pouch precancerous lesions were treated with either topical ALA-PDT with topical MTX pretreatment (topical MTX-ALA-PDT group, n = 10) or topical ALA-PDT alone (topical ALA-PDT group, n = 10). The intracellular protoporphyrin IX (PpIX) level in another 12 precancerous lesions (n = 6 for either the topical MTX-ALA or topical ALA group) was monitored by fluorescence spectroscopy. The intracellular PpIX reached its peak level in precancerous lesions 6.5 hours and 2.5 hours after topical ALA application for the topical MTX-ALA group (5.63-fold higher in the lesion than in the normal mucosa) and topical ALA group (2.42-fold higher in the lesion than in the normal mucosa), respectively. The complete response rate of precancerous lesions was 80% for the topical MTX-ALA-PDT group and 70% for the topical ALA-PDT group. In addition, the topical MTX-ALA-PDT group required a significantly lower mean treatment number (2.1 ± 0.6) to achieve complete response than the topical ALA-PDT group (4.4 ± 1.3, p < 0.001)). Moreover, the topical MTX-ALA-PDT group had a lower recurrence rate (12.5%) than the topical ALA-PDT group (28.6%). We conclude that topical MTX-pretreatment can increase intracellular PpIX production in hamster buccal pouch precancerous lesions and significantly improves the outcomes of the precancerous lesions treated with topical ALA-PDT.

During 1986 the authors came across two cases of brain abscess among children with congenital heart disease followed at the Pediatric Cardiology Service and decided to evaluate their global experience on the subject. In a retrospective study of 860 infants and children with cyanotic congenital heart disease and final diagnosis, there were four cases complicated with brain abscess. The following items were evaluated: prevalence of the complication, type of congenital heart disease, date and age at the diagnosis of brain abscess, diagnostic methods, neurosurgical treatment and results. The main findings were: all patients were above two years of age and had noncorrected cyanotic congenital heart disease belonging to the classic high risk group; the first two cases had been treated in other institutions and only scanty information was available; two recent cases had early diagnosis on CAT scan followed by neurosurgical treatment. All children survived. brain abscess is a rare but severe complication occurring in patients with noncorrected cyanotic congenital heart disease above two years of age; whenever prevention turns impossible, early diagnosis and treatment provide good short term and long term results. A multidisciplinar approach with full cooperation is advocated.

Since the introduction of cardiac surgery, the prospects for children born with a cardiac defect have improved spectacularly. Many reach adulthood and the population of adults with congenital heart disease is increasing and ageing. However, repair of congenital heart disease does not mean cure. Many adults with congenital heart disease encounter late complications. Late morbidity can be related to the congenital heart defect itself, but may also be the consequence of the surgical or medical treatment or longstanding alterations in hemodynamics, neurodevelopment and psychosocial development. This narrative review describes the cardiac and non-cardiac long-term morbidity in the adult population with congenital heart disease. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Expression of genes responsible for cell morphogenesis involved in differentiation in porcine buccal pouch mucosal cells during long-term primary culture and real-time proliferation in vitro.

Recently, using experimental animal model, we demonstrated that porcine buccal pouch mucosal cells reflect increased proliferation capability during primary cultivation in vitro. Although the histological structure and morphogenesis in oral cavity is well recognized, the molecular mechanisms which regulate this process still need further investigation. This study was aimed to analyze the molecular marker expression profile involved in morphogenesis and differentiation capacity of porcine buccal pouch mucosal cells during their long-term primary cultivation in vitro. The experiment was performed on buccal pouch mucosal cells isolated from 80 pubertal crossbred Landrace gilts. After collection, the cells were treated enzymatically and transferred into a primary in vitro culture (IVC) system and cultured for 30 days. The cells were collected for RNA isolation after 7, 15 and 30 days of IVC and were checked for their real-time proliferative status using the RTCA system. We found an increased expression of FN1 and SOX9 genes when calculated against ACTB after 7, and 30 days of IVC, (P less than 0.01, P less than 0.001, respectively). The CXCL12 mRNA was down-regulated after 7, 15 and 30 days of IVC, but not statistically significant. Similar expression profile was observed when calculated against HPRT, however, DAB2 was found to be higher expressed at day 15 of IVC, (P less than 0.05). The cell index measured during real-time cell proliferation was substantially increased between 96 h and 147h of IVC and reached the log phase. Since FN1 and SOX9 revealed significant increase of expression after long-term culture in vitro, it is suggested that expression of these differentiation and stemness genes is accompanied by cell proliferation. Moreover, FN1 and SOX9 might be recognized as new markers of buccal pouch mucosal cell proliferation and differentiation in pigs in in vitro primary culture model.

Colonic casts: unexpected complications of colonic ischaemia.

Introduction Extensive colonic ischaemia can result in passage of a colonic 'cast' (CC) through the rectum. Case Study We report a 69-year-old male who initially underwent surgery to remove a sessile polyp. On postoperative day (POD)15, he was febrile, suffering from diarrhoea, and was treated conservatively. On POD18, the patient returned to our hospital with a CC that presented after defaecation. Computed tomography of the abdomen revealed a CC extending from the descending colon to the anal orifice with presentation of air between the affected colonic wall and the CC. The patient was treated conservatively and discharged on POD20 without complications having passed the CC (≈80cm) completely and becoming afebrile. Conclusions In most cases, the cause of CC passage is surgery for colorectal cancer or repair of an abdominal aortic aneurysm. A mild-to-severe presentation is dependent upon the bowel-wall layers affected by ischaemia and which therefore are included in the CC.

Herein we report the case of a patient with primary amenorrhea and cyclic menouria. The patient was a 20-year-old woman with primary amenorrhea and inability to achieve sexual intercourse. Clinical examination revealed normally developed labia majora and minora, clitoris, and external urethral orifice, but no vaginal opening. A mature female pubic hair pattern was present, and axillary hair development was normal. Breasts were normally developed. Abdominopelvic magnetic resonance imaging demonstrated a remnant upper vagina and unicornuate uterus filled with fluid, and left-sided renal agenesis. Intraoperatively, a congenital vesicouterine fistulous tract was observed. The fistulous tract was completely resected. Vaginal reconstruction using a sigmoid colon pedicled flap was performed. The proximal part of the neovagina was connected to the remnant cervix, and a Foley catheter was left in the uterine cavity for 7 days to prevent obstruction. The patient has been menstruating regularly since the operation. Menouria might be an early sign of congenital vesicouterine fistula. Resection of the fistulous tract with uterine preservation might be considered in patients with vaginal agenesis. Copyright © 2011 AAGL. Published by Elsevier Inc. All rights reserved.

Pediatric congenital intracranial infections are a group of different and important entities that constitute a small percentage of all pediatric infections. The causal factors and clinical presentations are different in children compared with adults. They require early recognition because delay diagnosis and initiation of treatment may have catastrophic consequences. Despite improvements in prenatal screening, vaccine safety, and antibiotics, infections of the central nervous system remain an important cause of neurological disabilities worldwide. This article reviews the most common congenital infections and their imaging findings.

To determine the prevalence of congenital heart defects (CHDs) in patients with mild or severe congenital anorectal malformations (CARMs), and whether all patients with CARM need pediatric cardiology screening. We included 129 patients with CARM born between 2004 and 2013, and referred to University Medical Center Groningen. Recto-perineal and recto-vestibular fistulas were classified as mild CARMs, all others as severe. Significant patent foramen ovale, secundum atrial septal defect, and small ventricular septum defect were classified as minor CHDs, all others as major. Of 129 patients with CARM, 67% had mild CARM, 33% severe CARM, and 17% were additionally diagnosed with CHD. CHDs were distributed equally in patients with mild or severe CARMs. Patients with multiple congenital abnormalities were more frequently diagnosed with CHD (n = 16, 36%) than patients without multiple congenital malformations (n = 5, 9%, P = .001). Patients with CARM diagnosed with CHD using pediatric cardiac echo screening were younger than 3 months of age at diagnosis. Earlier general pediatric examinations missed 7 (50%) children with mild and 4 (50%) with severe CHDs. The severity of CARM could predict neither prevalence nor severity of CHD. More than one-half of CHDs were missed during the first physical examination. No new CHDs were found in patients older than 3 months of age at the time CARMs were diagnosed. We recommend screening all patients with CARM younger than 3 months of age for CHD at the time CARM is diagnosed. Preoperative echocardiography should be the rule in children younger than 3 months of age and with multiple congenital anomalies. Copyright © 2016 Elsevier Inc. All rights reserved.

To study the clinical features of congenital syphillis presenting congenital nephrotic syndrome (CNS) in children. Two cases diagnosed as congenital syphillis presenting CNS in our hospital were retrospectively analyzed and related data reviewed. The two children had edema, gross proteinuria, haematuria, hepatosplenomegaly, abdominal distention and anaema. Rapid plasmin regain (RPR) and treponema palidum hemagglutination assay (TPHA) were all positive. One chiild was also had renal biopsy and showed membraous nephropathy. Adequate penicillin therapy got satisfatory effects without steroid treatment. For children with early occurrence of proteinuria, edema accompanied by anaema, and hepatosplenomegaly, we should conside the possibility of syphillis nephropathy, which should be treated with enough dosage of penicillin in instead of steroid. Early diagnosis and treatmen could get complete recovery of CNS.

Numerous studies have found that congenitally blind individuals have better verbal memory than their normally sighted counterparts. However, it is not known whether this reflects superiority of verbal or memory abilities. In order to distinguish between these possibilities, we tested congenitally blind participants and normally sighted control participants, matched for age and education, on a range of verbal and spatial tasks. Congenitally blind participants were significantly better than sighted controls on all the verbal tasks but the groups did not differ significantly on the spatial tasks. Thus, the congenitally blind appear to have superior verbal, but not spatial, abilities. This may reflect greater reliance on verbal information and the involvement of visual cortex in language processing in the congenitally blind.

Cystic urolithiasis is the most common form of urolithiasis reported in horses. In contrast to the gelding or stallion, clinical disease is less common in the mare and manual removal techniques are possible because of their shorter, wider urethral anatomy. However, these manual removal techniques can be traumatic and are limited by the size of the urolith. This report describes the use of a commercial laparoscopic specimen pouch to remove a cystic urolith in a mare. This approach may allow the extraction of larger uroliths per urethra in the mare, while affording some protection to the mucosa of the bladder neck and urethra. © 2017 Australian Veterinary Association.

Primary congenital hypothyroidism is frequently seen endocrine disorder and one of the preventable cause of mental retardation. Aim of study was to evaluate the frequency of permanent/transient hypothyrodism, and to detect underlying reason to identfy any marker which carries potential to discriminate permanent/transient form. Forty eight cases older than 3 years of age, diagnosed as primary congenital hypothyroidism and started thyroxin therapy in newborn-period, and followed up between January 2007-June 2013 were included in the study. Thyroid hormon levels were evaluated and thyroid ultrasonography was performed in cases who are at the end of their 3 years of age, after 6 weeks of thyroxine free period. Thyroid sintigraphy was performed if serum thyroid-stimulating hormone was high (≥ 5 mIU/mL) and perchlorate discharge test was performed if uptake was normal or increased on sintigraphy. Cases with thyroid-stimulating hormone levels ≥ 5 mIU/mL were defined as permanent primary congenital hypothyroidism group and as transient primary congenital hypothyroidism group with normal thyroid hormones during 6 months. The mean age was 3.8±0.7 years. Mean diagnosis age was 16.6±6.5 days and 14 cases (29.2%) were diagnosed by screening program of Ministry of Health. There were 23 cases (14F, 9M) in permanent primary congenital hypothyroidism group and 12 (52.2%) of them were dysgenesis (8 hypoplasia, 4 ectopia), and 11 (47.8%) dyshormonogenesis. In transient primary congenital hypothyroidism group, there were 25 cases (17M, 8F). The mean thyroid-stimulating hormone levels at diagnosis were similar in two groups. The mean thyroxin dose in permanent primary congenital hypothyroidism group was significantly higher than transient group at the time of thyroxin cessation (2.1±0.7, 1.5±0.5 mg/kg/d, respectively, p=0.004). Thyroxin dose ≥1.6 mcg/kg/d was 72% sensitive and 69.6% specific for predicting permenant primary congenital hypothyroidism. Transient primary

Congenital hydrocephalus is an important birth defect, the genetics of which remains incompletely understood. To date, only 4 genes are known to cause Mendelian diseases in which congenital hydrocephalus is the main or sole clinical feature, 2 X-linked (L1CAM and AP1S2) and 2 autosomal recessive (CCDC88C and MPDZ). In this study, we aimed to determine the genetic etiology of familial congenital hydrocephalus with the assumption that these cases represent Mendelian forms of the disease. Exome sequencing combined, where applicable, with positional mapping. We identified a likely causal mutation in the majority of these families (21 of 27, 78%), spanning 16 genes, none of which is X-linked. Ciliopathies and dystroglycanopathies were the most common etiologies of congenital hydrocephalus in our cohort (19% and 26%, respectively). In 1 family with 4 affected members, we identified a homozygous truncating variant in EML1, which we propose as a novel cause of congenital hydrocephalus in addition to its suggested role in cortical malformation. Similarly, we show that recessive mutations in WDR81, previously linked to cerebellar ataxia, mental retardation, and disequilibrium syndrome 2, cause severe congenital hydrocephalus. Furthermore, we confirm the previously reported candidacy of MPDZ by presenting a phenotypic spectrum of congenital hydrocephalus associated with 5 recessive alleles. Our study highlights the importance of recessive mutations in familial congenital hydrocephalus and expands the locus heterogeneity of this condition.

Roles for FGF in lamprey pharyngeal pouch formation and skeletogenesis highlight ancestral functions in the vertebrate head.

A defining feature of vertebrates (craniates) is a pronounced head supported and protected by a cellularized endoskeleton. In jawed vertebrates (gnathostomes), the head skeleton is made of rigid three-dimensional elements connected by joints. By contrast, the head skeleton of modern jawless vertebrates (agnathans) consists of thin rods of flexible cellular cartilage, a condition thought to reflect the ancestral vertebrate state. To better understand the origin and evolution of the gnathostome head skeleton, we have been analyzing head skeleton development in the agnathan, lamprey. The fibroblast growth factors FGF3 and FGF8 have various roles during head development in jawed vertebrates, including pharyngeal pouch morphogenesis, patterning of the oral skeleton and chondrogenesis. We isolated lamprey homologs of FGF3, FGF8 and FGF receptors and asked whether these functions are ancestral features of vertebrate development or gnathostome novelties. Using gene expression and pharmacological agents, we found that proper formation of the lamprey head skeleton requires two phases of FGF signaling: an early phase during which FGFs drive pharyngeal pouch formation, and a later phase when they directly regulate skeletal differentiation and patterning. In the context of gene expression and functional studies in gnathostomes, our results suggest that these roles for FGFs arose in the first vertebrates and that the evolution of the jaw and gnathostome cellular cartilage was driven by changes developmentally downstream from pharyngeal FGF signaling.

To systematically review the current literature on treatment of third and fourth branchial pouch sinuses with endoscopic cauterization, including chemocauterization and electrocauterization, in comparison to surgical treatment. PubMed, Embase, and the Cochrane Library. We conducted a systematic search. Studies reporting original study data were included. After assessing the directness of evidence and risk of bias, studies with a low directness of evidence or a high risk of bias were excluded from analysis. Cumulative success rates after initial and recurrent treatments were calculated for both methods. A meta-analysis was conducted comparing the success rate of electrocauterization and surgery. A total of 2,263 articles were retrieved, of which seven retrospective and one prospective article were eligible for analysis. The cumulative success rate after primary treatment with cauterization ranged from 66.7% to 100%, and ranged from 77.8% to 100% after a second cauterization. The cumulative success rate after the first surgical treatment ranged from 50% to 100% and was 100% after the second surgical attempt. Meta-analysis on electrocauterization showed a nonsignificant risk ratio of 1.35 (95% confidence interval: 0.78-2.33). The effectiveness of cauterization in preventing recurrence seems to be comparable to surgical treatment. However, we suggest endoscopic cauterization as the treatment of choice for third and fourth branchial pouch sinuses because of the lower morbidity rate. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Genital ureaplasmas are considered opportunistic pathogens of human genitourinary tract involved in adverse pregnancy sequelae and infertility. While association of Ureaplasma urealyticum with urogenital tract infections is well established, the role of Ureaplasma parvum in these infections is still insufficient. In the study, we compared how often cervicovaginal colonization with U. parvum is associated with the presence of these microorganisms in the upper genitourinary tract of fertile and infertile women. We used PCR assay to determine the prevalence of U. parvum and U. urealyticum in pairs of specimens, i.e., vaginal swabs and Douglas' pouch fluid samples from consecutive 40 women with no symptoms of genital tract infection. In total, 19 (47.5 %) of the 40 samples were positive for ureaplasmas. U. parvum was simultaneously detected in pairs of samples in five (55.5 %) of the nine (47.4 %) women positive in PCR assay. As many as 5 (18.5 %) of the 27 infertile women and 1 (7.7 %) of the 13 fertile women showed infection of the upper genital tract with U. parvum. The results of the study demonstrated that colonization of the lower genital tract with U. parvum can produce asymptomatic infection of the upper reproductive system in women. These findings also imply that U. parvum may be present in the upper genital tract at the time of conception and might be involved in adverse pregnancy outcomes.

Lab-on-a-chip devices are often applied to point-of-care diagnostic solutions as they are low-cost, compact, disposable, and require only small sample volumes. For such devices, various reagents are required for sample preparation and analysis and, for an integrated solution to be realized, on-chip reagent storage and automated introduction are required. This work describes the implementation and characterization of effective liquid reagent storage and release mechanisms utilizing blister pouches applied to various point-of-care diagnostic device applications. The manufacturing aspects as well as performance parameters are evaluated.

Genetics of Congenital Heart Disease: Past and Present.

Congenital heart disease is the most common congenital anomaly, representing an important cause of infant morbidity and mortality. Congenital heart disease represents a group of heart anomalies that include septal defects, valve defects, and outflow tract anomalies. The exact genetic, epigenetic, or environmental basis of congenital heart disease remains poorly understood, although the exact mechanism is likely multifactorial. However, the development of new technologies including copy number variants, single-nucleotide polymorphism, next-generation sequencing are accelerating the detection of genetic causes of heart anomalies. Recent studies suggest a role of small non-coding RNAs, micro RNA, in congenital heart disease. The recently described epigenetic factors have also been found to contribute to cardiac morphogenesis. In this review, we present past and recent genetic discoveries in congenital heart disease.

The objectives of this review are to discuss the pathophysiology, clinical impact and treatment of major noncardiac anomalies, and prematurity in infants with congenital heart disease. MEDLINE and PubMed. Mortality risk is significantly higher in patients with congenital heart disease and associated anomalies compared with those in whom the heart defect occurs in isolation. Although most noncardiac structural anomalies do not require surgery in the neonatal period, several require surgery for survival. Management of such infants poses multiple challenges. Premature infants with congenital heart disease face challenges imposed by their immature organ systems, which are susceptible to injury or altered function by congenital heart disease and abnormal circulatory physiology independent of congenital heart disease. For optimal outcomes in premature infants or in infants with multiple congenital anomalies, a collaborative interdisciplinary approach is necessary.

Analysis of the prevalence of selected congenital anomalies in the Czech Republic in 1994-2009. Retrospective epidemiological analysis of the postnatal and overall (including prenatally diagnosed cases) prevalence of congenital anomalies from the database of the National Registry of Congenital Anomalies of the Czech Republic. Data from the National Registry of Congenital Anomalies (NRCA) maintained by the Institute of Health Information and Statistics of the Czech Republic (IHIS CR) were used. The analysis was carried out for the entire Czech Republic, based on the data from 1994 to 2009. Additional data on prenatally diagnosed anomalies were obtained from medical genetics centres and laboratories in the Czech Republic. This study analyzed the postnatal and overall (including prenatally diagnosed cases) prevalence of congenital anomalies. More detailed analysis was carried out for the following diagnoses: anencephaly, spina bifida, encephalocoele, congenital hydrocephalus, omphalocoele, gastroschisis, oesophageal atresia and stenosis, anorectal anomalies, and diaphragmatic hernia. Prevalence trends were analysed using Poisson regression. In 2009, a total of 118 348 live births were recorded in the Czech Republic, 60 368 boys and 57 980 girls. Of this total, 4 653, i.e. 2 745 boys and 1 908 girls, were diagnosed with congenital anomalies. In 2007-2009, the total of life births with congenital anomalies ranged between 4.6 and 4.8 thousand per year. The respective ranges in this three-year period were in the order of 2.7 and 2.8 thousand per year for boys and 1.9 thousand per year for girls. The prevalence of postnatally diagnosed anencephaly was minimal, as most cases were diagnosed prenatally, and the data did not vary significantly. The prevalence of postnatally diagnosed cases remained at the same level. The effectiveness of the prenatal diagnosis of spina bifida increased and thus the prevalence of postnatally diagnosed cases decreased. The prevalence of

In Portugal the screening for phenylketonuria (PKU) and congenital hypothyroidism (CH) was begun towards the end of 1979, and by 1990 59 cases of PKU and 227 cases of CH had been detected. The early initiation of treatment and the observed mental and motor development, point towards a normal development in these children. A trial screen for congenital adrenal hyperplasia was carried out in 100.000 newborns, from which it was concluded that, under the present conditions, screening at a national level is not justified. A similar study is currently being undertaken for biotinidase deficiency and cystic fibrosis. The results ares discussed, as are the cost/benefits evaluations.

Colon-targeted drug delivery and circumventing drug resistance are extremely important for colon cancer chemotherapy. Our previous work found that dimethyl fumarate (DMF), the approved drug by the FDA for the treatment of multiple sclerosis, exhibited anti-tumor activity on colon cancer cells. Based on the pharmacological properties of DMF and azo bond in olsalazine chemical structure, we designed azo polymeric micelles for colon-targeted dimethyl fumarate delivery for colon cancer therapy. We synthesized the star-shape amphiphilic polymer with azo bond and fabricated the DMF-loaded azo polymeric micelles. The four-arm polymer star-PCL-azo-mPEG (sPCEG-azo) (constituted by star-shape PCL (polycaprolactone) and mPEG (methoxypolyethylene glycols)-olsalazine) showed self-assembly ability. The average diameter and polydispersity index of the DMF-loaded sPCEG-azo polymeric micelles were 153.6nm and 0.195, respectively. In vitro drug release study showed that the cumulative release of DMF from the DMF-loaded sPCEG-azo polymeric micelles was no more than 20% in rat gastric fluid within 10h, whereas in the rat colonic fluids, the cumulative release of DMF reached 60% in the initial 2h and 100% within 10h, indicating that the DMF-loaded sPCEG-azo polymeric micelles had excellent colon-targeted property. The DMF-loaded sPCEG-azo polymeric micelles had no significant cytotoxicity on colon cancer cells in phosphate buffered solution (PBS) and rat gastric fluid. In rat colonic fluid, the micelles showed significant cytotoxic effect on colon cancer cells. The blank sPCEG-azo polymeric micelles (without DMF) showed no cytotoxic effect on colon cancer cells in rat colonic fluids. In conclusion, the DMF-loaded sPCEG-azo polymeric micelles show colon-targeted DMF release and anti-tumor activity, providing a novel approach potential for colon cancer therapy. Colon-targeted drug delivery and circumventing drug resistance are extremely important for colon cancer chemotherapy. Our

Sacral agenesis is a rare congenital defect which is associated with foot deformities such as congenital talipes equinovarus (CTEV) and less commonly congenital vertical talus (CVT). We report a 3-year-old Caucasian girl who was born with right CTEV and left CVT secondary to sacral agenesis. Her right foot was managed with a Ponseti casting method at 2 weeks, followed by an Achilles tenotomy at 4 months. The left foot was initially managed with a nocturnal dorsi-flexion splint. Both feet remained resistant and received open foot surgery at 10 months producing plantigrade feet with neutral hindfeet. At 19 months, she failed to achieve developmental milestones and examinations revealed abnormal lower limb reflexes. A full body MRI was performed which identified the sacral agenesis. We advocate early MRI of the spine to screen for spinal defects when presented with resistant foot deformities, especially when bilateral. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

To observe dynamically that Erigeron Breviscapus (Vant) Hand-Mazz (HEr) affects the expression of alpha-smooth muscle actin (alpha-SMA). To discuss the probable mechanism of obstructing leukoplakia carcinogenesis of this medicine. 120 golden hamsters were randomly divided into model group (48), HEr group (48) and control group (6). HEr was applied to obstruct the evolution of carcinogenesis of golden hamster cheek pouch. Immunohistochemistry was used to detect the expression level of alpha-SMA with cheek pouch specimen that besmears DMBA in 4-9 weeks. Results were compared with model group. Vessel density dyed with alpha-SMA continuously of HEr group was 65.76 significantly higher than that of model group 42.12 (P<0.001). High classification cases in HEr group were much more than model group when cases were divided into five groups as follow: 100%, 50%, 20%, 10%, 3% (P<0.01). HEr can raise the expression level of alpha-SMA exactly during the evolution of leukoplakia carcinogenesis of golden hamster, which shows that this medicine obstructs carcinogenesis by keeping the normal physiological function of vascular myoepithelial cell and integrity of vascular basement membrane.

Changing perspectives in screening for congenital hypothyroidism and congenital adrenal hyperplasia.

Mitchell, Marvin L; Hsu, Ho-Wen; Sahai, Inderneel

2014-02-01

The purpose of this review is to summarize recent information that has had a significant impact on the laboratory diagnosis and clinical management of newborns with congenital hypothyroidism and congenital adrenal hyperplasia (CAH). An approximate doubling of the incidence rate of congenital hypothyroidism in many parts of the world has been attributed to increased detection of infants with mild disease, delayed thyroid stimulating hormone elevations and demographic changes. A substantial number of children with modest thyroid stimulating hormone elevations on screening have permanent disease. Circulating levels of thyroxine may vary among hypothyroid children who are given identical dosages of medication. Treated infants should be monitored every 1-2 months during the first year of life. Although, generic and brand name thyroxine preparations may not be bioequivalent, children can be well controlled on generic formulations.Enzyme linked immunoassay assay for 17-hydroxyprogesterone is associated with a high rate of false positive specimens. In attempts to minimize this problem, some programs have resorted to two-tier screening of the initial specimen with steroid profiling as the second tier. Several programs are routinely testing second specimens in an effort to reduce the incidence of missed CAH cases. This review explains the uptick in incidence rate of congenital hypothyroidism and underscores issues in management that can affect developmental outcome. One specimen two-tier testing for CAH resulted in an increased false negative rate without significantly reducing the false positive rate. The benefit of collecting second specimens for CAH screening is problematic. Optimal treatment of CAH continues to pose a challenge.

This article reviews the changing epidemiology of congenital heart disease summarizing its impact on the demographics of the congenital heart disease population and the progress made in order to improve outcomes in this patient population. Birth prevalence of congenital heart disease can be modified by many factors. As a result of decreasing mortality and increasing survival in all forms of congenital heart disease, the median age of patients has increased and adults now compose two-thirds of patients with congenital heart disease. Disease burden and resulting health services utilization increase significantly across the lifespan. Bridging the gap between policy and quality of care can be improved by referral to specialized adult congenital heart disease centers and planning delivery of specialized services that are commensurate with population needs, program accreditation criteria and certified training of designated workforce.

The congenital heart disease includes abnormalities in heart structure that occur before birth. Such defects occur in the fetus while it is developing in the uterus during pregnancy. About 500,000 adults have congenital heart disease in USA (WebMD, Congenital heart defects medications, www.WebMD.com/heart-disease/tc/congenital-heart-defects-medications , 2014). 1 in every 100 children has defects in their heart due to genetic or chromosomal abnormalities, such as Down syndrome. The excessive alcohol consumption during pregnancy and use of medications, maternal viral infection, such as Rubella virus, measles (German), in the first trimester of pregnancy, all these are risk factors for congenital heart disease in children, and the risk increases if parent or sibling has a congenital heart defect. These are heart valves defects, atrial and ventricular septa defects, stenosis, the heart muscle abnormalities, and a hole inside wall of the heart which causes defect in blood circulation, heart failure, and eventual death. There are no particular symptoms of congenital heart disease, but shortness of breath and limited ability to do exercise, fatigue, abnormal sound of heart as heart murmur, which is diagnosed by a physician while listening to the heart beats. The echocardiogram or transesophageal echocardiogram, electrocardiogram, chest X-ray, cardiac catheterization, and MRI methods are used to detect congenital heart disease. Several medications are given depending on the severity of this disease, and catheter method and surgery are required for serious cases to repair heart valves or heart transplantation as in endocarditis. For genetic study, first DNA is extracted from blood followed by DNA sequence analysis and any defect in nucleotide sequence of DNA is determined. For congenital heart disease, genes in chromosome 1 show some defects in nucleotide sequence. In this review the causes, diagnosis, symptoms, and treatments of congenital heart disease are described.

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.

Congenital malaria in Urabá, Colombia

PubMed Central

2011-01-01

Background Congenital malaria has been considered a rare event; however, recent reports have shown frequencies ranging from 3% to 54.2% among newborns of mothers who had suffered malaria during pregnancy. There are only a few references concerning the epidemiological impact of this entity in Latin-America and Colombia. Objective The aim of the study was to measure the prevalence of congenital malaria in an endemic Colombian region and to determine some of its characteristics. Methods A prospective, descriptive study was carried out in the mothers who suffered malaria during pregnancy and their newborns. Neonates were clinically evaluated at birth and screened for Plasmodium spp. infection by thick smear from the umbilical cord and peripheral blood, and followed-up weekly during the first 21 days of postnatal life through clinical examinations and thick smears. Results 116 newborns were included in the study and 80 umbilical cord samples were obtained. Five cases of congenital infection were identified (four caused by P. vivax and one by P. falciparum), two in umbilical cord blood and three in newborn peripheral blood. One case was diagnosed at birth and the others during follow-up. Prevalence of congenital infection was 4.3%. One of the infected newborns was severely ill, while the others were asymptomatic and apparently healthy. The mothers of the newborns with congenital malaria had been diagnosed with malaria in the last trimester of pregnancy or during delivery, and also presented placental infection. Conclusions Congenital malaria may be a frequent event in newborns of mothers who have suffered malaria during pregnancy in Colombia. An association was found between congenital malaria and the diagnosis of malaria in the mother during the last trimester of pregnancy or during delivery, and the presence of placental infection.

1997-01-01

The effects of a purified micronized flavonoid fraction (S5682) on mean internal diameter and blood flow of arterioles and venules, as well as the functional capillary density (FCD) were evaluated in the hamster cheek pouch microvasculature before and after 90 min of total ischaemia. Male hamsters were treated for ten days, twice a day, with oral doses of S5682 (5, 20, 80 and 160 mg kg−1 day−1) or placebo (10% lactose solution). The cheek pouch preparation was placed under an intravital microscope coupled to a closed circuit TV system. Local ischaemia was obtained by a cuff mounted around the neck of the everted pouch where it leaves the mouth of the hamster. Measurements were performed before ischaemia, at the onset of reperfusion and 10, 20, 30, 45 and 60 min thereafter. Diameters were measured by means of an image shearing device. Red blood cell (RBC) velocity was analysed by use of the dual-slit photometric technique. Blood flow was calculated from diameters and RBC velocities. FCD, defined as the number of capillaries with flowing blood per field of observation, was also assessed. During reperfusion, placebo-treated animals showed a significant vasodilatation, a decrease in blood flow and FCD and S5682-treated animals showed a clear trend, dose-dependent, towards maintaining these parameters closer to the value found before ischaemia. In conclusion, our results indicate that S5682 improves the microvascular reactivity and FCD after ischaemia/reperfusion. These data suggest that S5682 could function as an antioxidant, which may explain its beneficial therapeutic effect in chronic venous insufficiency where oxidative stress is involved in the pathological mechanism.

Cotes, Claudia; Bonfante, Eliana; Lazor, Jillian; Jadhav, Siddharth; Caldas, Maria; Swischuk, Leonard

2015-01-01

The classification of posterior fossa congenital anomalies has been a controversial topic. Advances in genetics and imaging have allowed a better understanding of the embryologic development of these abnormalities. A new classification schema correlates the embryologic, morphologic, and genetic bases of these anomalies in order to better distinguish and describe them. Although they provide a better understanding of the clinical aspects and genetics of these disorders, it is crucial for the radiologist to be able to diagnose the congenital posterior fossa anomalies based on their morphology, since neuroimaging is usually the initial step when these disorders are suspected. We divide the most common posterior fossa congenital anomalies into two groups: 1) hindbrain malformations, including diseases with cerebellar or vermian agenesis, aplasia or hypoplasia and cystic posterior fossa anomalies; and 2) cranial vault malformations. In addition, we will review the embryologic development of the posterior fossa and, from the perspective of embryonic development, will describe the imaging appearance of congenital posterior fossa anomalies. Knowledge of the developmental bases of these malformations facilitates detection of the morphological changes identified on imaging, allowing accurate differentiation and diagnosis of congenital posterior fossa anomalies.

An atrial septal pouch (ASP) results from partial fusion of the septum primum and the septum secundum, and depending on the site of fusion, the pouch can be left-sided (LASP) or right-sided (RASP). LASPs have been described in association with thrombi found in patients admitted with acute strokes, raising awareness of its potential cardioembolic role, especially in those with no other clearly identifiable embolic source. We retrospectively studied 39 patients in whom the presence of an ASP had been identified by three-dimensional transesophageal echocardiography (3DTEE) and who had a two-dimensional transesophageal echocardiogram (2DTEE) performed during the same clinical encounter. The incremental value provided by 3DTEE over 2DTEE included the detection of six ASPs not found by 2DTEE; the detection of two ASPs in the same subject (in four patients) not identified by 2DTEE; larger ASP measurements of length and height in over 80% of the cases; and measurement of the ASP width (elevational axis) for the calculation of the area of the ASP opening, because of its unique capability to view the pouch en face. In addition, the volume of ASP and of the echogenic masses contained in the ASP (four of 39 patients) could be calculated by 3DTEE, which is a superior parameter of size characterization when compared to individual dimensions. One of these patients who presented with ischemic stroke diagnosed by magnetic resonance imaging had a large (>2 cm) mass in a LASP, with echolucencies similar to those seen in thrombi and associated with clot lysis and resolution. This mass completely disappeared on anticoagulant therapy lending credence that it was most likely a thrombus. There was no history of stroke or any other type of embolic event in the other three patients with masses in ASP. In conclusion, this retrospective study highlights the incremental value of 3DTEE over 2DTEE in the comprehensive assessment and characterization of ASPs, which can aid in the clarification of

Cytomegalovirus (CMV) is the most frequent cause of congenital infection, and both symptomatic and asymptomatic infants may have long term sequelae. Children with congenital CMV infection are chronically infected and excrete CMV in the urine for prolonged periods. However, the effect of prolonged viral replication on the long term outcome of these children is unknown. To determine whether duration of CMV excretion is associated with outcome at 6 years of life in symptomatic and asymptomatic congenitally infected children. Longitudinal cohort study. Children congenitally infected with CMV were identified at birth and followed prospectively in a study of long term effects of congenital CMV infection. The relationship between duration of CMV urinary excretion and growth, neurodevelopment and presence and progression of sensorineural hearing loss (SNHL) at 6 years of age was determined. There was no significant difference in the duration of viral urinary excretion between children born with asymptomatic (median, 4.55 years) and symptomatic (median, 2.97 years) congenital CMV infection (P = 0.11). Furthermore there was no association between long term growth or cognitive outcome and duration of viral excretion. However, a significantly greater proportion of children who excreted CMV for <4 years had SNHL and progressive SNHL compared with children with CMV excretion >4 years (P = 0.019, P = 0.009, respectively). Children congenitally infected with CMV are chronically infected for years, but the duration of CMV urinary excretion is not associated with abnormalities of growth, or neurodevelopmental deficits. However, SNHL and progressive SNHL were associated with a shorter duration of CMV excretion.

Gender influences the clinical presentation and the management of some acquired cardiovascular diseases, such as coronary artery disease, resulting in different outcomes. Differences between women and men are also noticed in congenital heart disease. They are mainly related to the prevalence and severity of some congenital heart defects at birth, and in adulthood to the prognosis, incidence of Eisenmenger syndrome and risks of pregnancy.

Infection with parainfluenza virus typically produces a mild, self-limited upper respiratory infection. However, parainfluenza infections have become increasingly recognized as a source of severe morbidity and mortality in immunocompromised patients. In this retrospective study we identified 6 patients with congenital immunodeficiency and positive respiratory cultures for parainfluenza virus who died and underwent complete autopsy. Tissues obtained at autopsy were studied using hematoxylin and eosin-stained sections, immunoperoxidase staining for parainfluenza virus, and in selected cases, electron microscopy. All 6 patients exhibited typical cytopathic effects of parainfluenza virus, including giant cell formation, in lung and/or bronchial tissues. Parainfluenza virus infection was also documented by giant cell formation and immunohistochemistry in the pancreas (in 3 of 6 patients) and the kidney or bladder (in 2 of 4 patients). Anti-parainfluenza antibody also specifically reacted with cells in the gastrointestinal tract (in 2 of 4), spleen (in 4 of 6), thymus and/or lymph nodes (in 4 of 4), and small blood vessels in various organs (in 4 of 6). Pancreatic, bladder, colon, and thymic epithelial cell lines were susceptible to experimental infections with clinical isolates of parainfluenza virus type 3 in vitro. Parainfluenza virus infection was serious in patients with congenital immunodeficiencies, contributing directly to death in 5 of the 6 patients studied. Because this virus is capable of infecting tissues in the gastrointestinal and urinary systems as well as in the respiratory tract, body secretions and fluids from each of these locations should be considered potentially infectious.

Sequential segmental classification of feline congenital heart disease.

PubMed

Scansen, Brian A; Schneider, Matthias; Bonagura, John D

2015-12-01

Feline congenital heart disease is less commonly encountered in veterinary medicine than acquired feline heart diseases such as cardiomyopathy. Understanding the wide spectrum of congenital cardiovascular disease demands a familiarity with a variety of lesions, occurring both in isolation and in combination, along with an appreciation of complex nomenclature and variable classification schemes. This review begins with an overview of congenital heart disease in the cat, including proposed etiologies and prevalence, examination approaches, and principles of therapy. Specific congenital defects are presented and organized by a sequential segmental classification with respect to their morphologic lesions. Highlights of diagnosis, treatment options, and prognosis are offered. It is hoped that this review will provide a framework for approaching congenital heart disease in the cat, and more broadly in other animal species based on the sequential segmental approach, which represents an adaptation of the common methodology used in children and adults with congenital heart disease.

Congenital aural atresia.

PubMed

Abdel-Aziz, Mosaad

2013-07-01

Congenital aural atresia is a spectrum of ear deformities present at birth that involves some degree of failure of the development of the external auditory canal. This malformation may be associated with other congenital anomalies; it occurs as a result of abnormal development of the first and second branchial arches and the first branchial cleft and most often occurs sporadically, although the disease may be manifested in different syndromes. Congenital aural atresia is considered one of the most difficult and challenging surgeries for the otologic surgeon. The goals of atresia surgery are to restore functional hearing, preferably without the requirement of a hearing aid, and to reconstruct a patent, infection-free external auditory canal. The repair is usually done at the age of 6 years, so children with bilateral atresia may need hearing amplification in the first few weeks of life until the age at surgery. To optimize the surgical outcome, careful audiological and radiological evaluation of the patient should be performed preoperatively. Also, postoperative frequent packing and regular follow-up are mandatory to avoid restenosis and infection of the newly created canal. With careful intraoperative dissection and regular follow-up, complications of surgery can be avoided.

Colonic diverticulosis may represent a risk factor for colonic adenomas by virtue of the fact that evolving data suggest that these 2 conditions may share common risk factors such as Western dietary pattern and physical inactivity. This study aims to investigate the association between colonic diverticulosis and colonic adenomas in mainland China. We conducted a cross-sectional study on patients who underwent colonoscopic examination between October 2013 and December 2014 in a university hospital in mainland China. Age, gender, colonic adenomas, advanced adenomas, and distribution of diverticulosis were recorded during the procedures. Multivariate logistic regression and stratified analysis were used to evaluate the associations between the prevalence of diverticulosis and age, sex, and presence of colonic adenomas and advanced adenomas. A total of 17,456 subjects were enrolled. The prevalence of colonic diverticulosis and adenoma was 2.4% and 13.2%, respectively. With regard to distribution of diverticula, most (365/424, 86.1%) were right-sided. Multiple logistic regression analysis suggested that age and male gender were independent risk factors for adenoma and advanced adenoma. There was no relationship between diverticulosis or location of diverticulosis and presence of adenoma and advanced adenoma adjusting by age and gender. In a stratified analysis according to age and gender, similar results were also noted. There was no statistical relationship between diverticulosis and the risk of adenoma and advanced adenoma. Our results may not be generalized to the Western population due to the fact that left-sided diverticular cases were very small in our study.

Zengshengping (ZSP) tablets had inhibitory effects on oral precancerous lesions by reducing the incidence of oral cancer. However, the severe liver toxicity caused by systemic administration of ZSP limits the long-term use of this anti-cancer drug. The purpose of this study was to evaluate the tumor inhibitory effects due to the topical application of extracts from ZSP, a Chinese herbal drug, on 7, 12-dimethlbenz(a)anthracene (DMBA) induced oral tumors in hamsters. The study also investigated the anti-cancer mechanisms of the ZSP extracts on oral carcinogenesis. DMBA (0.5%) was applied topically to the buccal pouches of Syrian golden hamsters (6 - 8 weeks old) three times per week for six weeks in order to induce the development of oral tumors. Different fractions of ZSP were either applied topically to the oral tumor lesions or fed orally at varying dosages to animals with oral tumors for 18 weeks. Tumor volume was measured by histopathological examination. Tumor cell proliferation was evaluated by counting BrdU labeled cells and by Western blotting for mitogen-activated protein kinase (MAPK) protein levels. The protein levels of apoptosis marker Caspase-3 and regulator Bcl-2 protein were also measured by Western blotting. Topical application of DMBA to the left pouch of hamsters induced oral tumor formation. Animals treated with DMBA showed a loss in body weight while animals treated with ZSP maintained normal body weights. Both the ZSP n-butanol fraction and water fraction significantly reduced tumor volume by 32.6% (P < 0.01) and 22.9% (P < 0.01) respectively. Topical application of ZSP also markedly decreased the BrdU-positive cell numbers in oral tumor lesions and reduced the expression level of MAPK. In addition, ZSP promoted tumor cell apoptosis by increasing Caspase-3 expression but decreasing Bcl-2 protein production. The n-butanol and water fractions of ZSP are effective at inhibiting tumor cell proliferation and stimulating apoptosis in oral cancer

Tcof1 acts as a modifier of Pax3 during enteric nervous system development and in the pathogenesis of colonic aganglionosis

Hirschsprung disease (HSCR) is a human congenital disorder, defined by the absence of ganglia from variable lengths of the colon. These ganglia comprise the enteric nervous system (ENS) and are derived from migratory neural crest cells (NCCs). The inheritance of HSCR is complex, often non-Mendelian and characterized by variable penetrance. Although extensive research has identified many key players in the pathogenesis of Hirschsprung disease, a large number of cases remain genetically undefined. Therefore, additional unidentified genes or modifiers must contribute to the etiology and pathogenesis of Hirschsprung disease. We have discovered that Tcof1 may be one such modifier. Haploinsufficiency of Tcof1 in mice results in a reduction of vagal NCCs and their delayed migration along the length of the gut during early development. This alone, however, is not sufficient to cause colonic aganglionosis as alterations in the balance of NCC proliferation and differentiation ensures NCC colonize the entire length of the gut of Tcof1+/− mice by E18.5. In contrast, Tcof1 haploinsufficiency is able to sensitize Pax3+/− mice to colonic aganglionosis. Although, Pax3 heterozygous mice do not show ENS defects, compound Pax3;Tcof1 heterozygous mice exhibit cumulative apoptosis which severely reduces the NCC population that migrates into the foregut. In addition, the proliferative capacity of these NCC is also diminished. Taken together with the opposing effects of Pax3 and Tcof1 on NCC differentiation, the synergistic haploinsufficiency of Tcof1 and Pax3 results in colonic aganglionosis in mice and may contribute to the pathogenesis of Hirschsprung disease.

Neurocutaneous melanocytosis is a rare congenital dysplasia of the neuroectodermal melanocyte precursor cells that leads to proliferation of melanin-producing cells in the skin and leptomeninges. We describe a newborn with a giant congenital melanocytic nevus on his back, buttocks, and thighs. His brain magnetic resonance imaging study revealed bilateral T1 hyperintense lesions in the cerebellum and in the amygdala, hydrocephalus, and a Blake's pouch cyst, consistent with neurocutaneous melanocytosis and Dandy-Walker malformation. Neurocutaneous melanocytosis has a wide clinical spectrum that includes hydrocephalus, epilepsy, cranial nerve palsy, increased intracranial pressure, and sensorimotor deficits. Copyright © 2014.

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.

Communication—indentation of Li-ion pouch cell: Effect of material homogenization on prediction of internal short circuit

Kumar, A.; Kalnaus, Sergiy; Simunovic, Srdjan; ...

2016-09-12

We performed finite element simulations of spherical indentation of Li-ion pouch cells. Our model fully resolves different layers in the cell. The results of the layer resolved models were compared to the models available in the literature that treat the cell as an equivalent homogenized continuum material. Simulations were carried out for different sizes of the spherical indenter. Here, we show that calibration of a failure criterion for the cell in the homogenized model depends on the indenter size, whereas in the layer-resoled model, such dependency is greatly diminished.

Liver involvement is common in patients with inflammatory bowel disease (IBD). However, the frequency and the significance of liver function test (LFT) abnormalities in patients with ileal pouch-anal anastomosis (IPAA) for underlying IBD have not been studied. The aim of this study was to evaluate the prevalence and to identify risk factors for abnormal LFTs in patients with IPAA and underlying IBD. All patients were identified from our prospectively maintained Pouchitis Database between 2002 and 2008. Abnormal LFTs were classified as the following: (i) any abnormal elevation of transaminases, and/or alkaline phosphatase (ALP), and/or bilirubin; (ii) hepatitis, if there was more than twice the elevation of transaminases; and (iii) cholestatic, if there was more than 1.5 times elevation of ALP. Clinical, endoscopic, and histological variables were assessed using Cox proportional hazard models for evaluating risk for abnormal LFTs. A total of 545 IPAA patients with underlying IBD were identified from the database, of which 373 patients who had LFTs done after their pouch surgery were included. This included 346 patients with ulcerative colitis, 25 with indeterminate colitis, and 2 with Crohn's colitis before surgery. Their mean age was 45.9+/-13.8 years. A total of 65 patients (17.4%) (40 men, 25 women, median age: 47 years) had abnormal LFTs. Of the patients, 52 (13.9%) had abnormal transaminases, whereas 15 (4%) were classified as having hepatitis. Thirty-five (9.4%) patients had an abnormal ALP level, with 18 (4.8%) classified as cholestatic. The most common cause of an abnormal LFT was transient elevation in 32 (49.2%) patients, followed by fatty liver (fatty change on imaging with body mass index (BMI) > or =25 kg/m(2) in the absence of other causes, including alcohol abuse and drug-induced hepatitis) in 10 (15.4%), drug-induced abnormal LFTs in 7 (10.7%), and chronic hepatitis B or C in 6 (9.2%).

Management of adolescents with congenital adrenal hyperplasia

PubMed Central

Merke, Deborah P; Poppas, Dix P

2014-01-01

The management of congenital adrenal hyperplasia involves suppression of adrenal androgen production, in addition to treatment of adrenal insufficiency. Management of adolescents with congenital adrenal hyperplasia is especially challenging because changes in the hormonal milieu during puberty can lead to inadequate suppression of adrenal androgens, psychosocial issues often affect adherence to medical therapy, and sexual function plays a major part in adolescence and young adulthood. For these reasons, treatment regimen reassessment is indicated during adolescence. Patients with non-classic congenital adrenal hyperplasia require reassessment regarding the need for glucocorticoid drug treatment. No clinical trials have compared various regimens for classic congenital adrenal hyperplasia in adults, thus therapy is individualised and based on the prevention of adverse outcomes. Extensive patient education is key during transition from paediatric care to adult care and should include education of females with classic congenital adrenal hyperplasia regarding their genital anatomy and surgical history. Common issues for these patients include urinary incontinence, vaginal stenosis, clitoral pain, and cosmetic concerns; for males with classic congenital adrenal hyperplasia, common issues include testicular adrenal rest tumours. Transition from paediatric to adult care is most successful when phased over many years. Education of health-care providers on how to successfully transition patients is greatly needed.

With the advances in congenital cardiac surgery and postoperative care, an increasing number of children with complex congenital heart disease now reach adulthood. There are already more adults than children living with a congenital heart defect, including patients with complex congenital heart defects. Among these adults with congenital heart disease, a significant number will develop ventricular dysfunction over time. Heart failure accounts for 26-42% of deaths in adults with congenital heart defects. Heart transplantation, or heart-lung transplantation in Eisenmenger syndrome, then becomes the ultimate therapeutic possibility for these patients. This population is deemed to be at high risk of mortality after heart transplantation, although their long-term survival is similar to that of patients transplanted for other reasons. Indeed, heart transplantation in adults with congenital heart disease is often challenging, because of several potential problems: complex cardiac and vascular anatomy, multiple previous palliative and corrective surgeries, and effects on other organs (kidney, liver, lungs) of long-standing cardiac dysfunction or cyanosis, with frequent elevation of pulmonary vascular resistance. In this review, we focus on the specific problems relating to heart and heart-lung transplantation in this population, revisit the indications/contraindications, and update the long-term outcomes.

Developmental genetics of congenital heart diseases has evolved from analysis of serial slices in embryos towards molecular genetics of cardiac morphogenesis with a dynamic view of cardiac development. Genetics of congenital heart diseases has also changed from formal genetic analysis of familial recurrences or population-based analysis to screening for mutations in candidates genes identified in animal models. Close cooperation between molecular embryologists, pathologists involved in heart development and pediatric cardiologists is crucial for further increase of knowledge in the field of cardiac morphogenesis and genetics of cardiac defects. The genetic model for congenital heart disease has to be revised to favor a polygenic origin rather than a monogenic one. The main mechanism is altered genic dosage that can account for heart diseases in chromosomal anomalies as well as in point mutations in syndromic and isolated congenital heart diseases. The use of big data grouping information from cardiac development, interactions between genes and proteins, epigenetic factors such as chromatin remodeling or DNA methylation is the current source for improving our knowledge in the field and to give clues for future therapies.

According to WHO hereditary diseases and congenital malformations contribute significantly to the health of population. Thus, the problems of epidemiology, clinical presentation, diagnosis and treatment of congenital abnormalities are of interest for many researchers [2]. In addition, the dynamic accounting for the incidence of congenital malformations and hereditary diseases allows the researchers to assess the ecological situation in the region [1]. The occurrence of congenital anomalies in the world varies; it depends heavily on how carefully the data is collected [4]. Multifactorial or polygenic diseases develop under the influence of environmental factors in the presence of defective genes. They can constitute up to 90% of all chronic pathology [2-5]. To determine the incidence of congenital anomalies under the influence of environmental factors. The study used the methodology of system evaluation of congenital anomalies incidence in Primorsky region, depending on bio-climatic and environmental conditions. The authors used health statistics for the period from 2000 to 2014, F.12 class for congenital abnormalities in adolescents and children that were compared in geographical and temporal aspects with environmental factors of 33 settlements in Primorsky region. The environment is represented by nature and climate (6 factor modules) and sanitation (7 factor modules) blocks of factors. When formalizing the information database of the environment a specially developed 10-point assessment scale was used. Statistical processing of the information was carried out using Pearson's chi-squared test and multiple regression method from SSPS application program package. The study found that over the 15-year period the level of congenital abnormalities in children increased by 27.5% and in adolescents - by 35.1%, and in 2014 it amounted to 1687.6 and 839.3 per 100 000 people, respectively. The predictive model shows a steady further growth of this pathology. The incidence

Congenital portosystemic shunt is a rare clinical entity that may progress to jaundice, severe encephalopathy, and pulmonary hypertension and require surgical correction or coil embolization. We present a novel approach to the management of children with congenital portosystemic shunt by means of a minimally invasive surgical technique. Congenital portosystemic shunts were identified between the superior mesenteric vein and inferior vena cava in case 1 and between the splenic vein and left renal vein in case 2. Both of them were successfully ligated by laparoscopic approach, and catheters were subsequently replaced to monitor portal venous pressure. The patients tolerated the procedure well, and short-term results were excellent. Laparoscopic ligation of congenital portosystemic shunt is technically feasible and less invasive to the management of patients with congenital portosystemic shunts, preventing late onset, life-threatening complications.

Colonic volvulus is a common cause of large bowel obstruction worldwide. It can affect all parts of the colon, but most commonly occurs in the sigmoid and cecal areas. This disease has been described for centuries, and was studied by Hippocrates himself. Currently, colonic volvulus is the third most common cause of large bowel obstruction worldwide, and is responsible for ∼15% of large bowel obstructions in the United States. This article will discuss the history of colonic volvulus, and the predisposing factors that lead to this disease. Moreover, the epidemiology and diagnosis of each type of colonic volvulus, along with the various treatment options will be reviewed. PMID:24294126

Recent increases in reported congenital syphilis have led to an urgent need to identify interventions that will have the greatest impact on congenital syphilis prevention. We sought to create a congenital syphilis prevention cascade using national syphilis surveillance data to (1) estimate the proportion of potential congenital syphilis cases averted with current prevention efforts, and (2) develop a classification framework to better describe why reported cases were not averted. We reviewed national syphilis and congenital syphilis case report data from 2016, including pregnancy status of all reported female syphilis cases and data on prenatal care, testing, and treatment status of mothers of reported congenital syphilis cases to derive estimates of the proportion of pregnant women with syphilis who received prenatal care, syphilis testing, and adequate syphilis treatment at least 30 days prior to delivery, as well as the proportion of potential congenital syphilis cases averted. Among the 2,508 pregnant women who were reported to have syphilis, an estimated 88.0% received prenatal care at least 30 days prior to delivery, 89.4% were tested for syphilis at least 30 days prior to delivery, and 76.9% received an adequate treatment regimen that began at least 30 days prior to delivery. Overall, an estimated 1,928 (75.0%) potential congenital syphilis cases in the United States were successfully averted. Among states that reported at least 10 syphilis cases among pregnant women, the estimated proportion of potential congenital syphilis cases averted ranged from 55.0% to 92.3%. While the majority of potential congenital syphilis cases in the United States were averted in 2016, there was substantial geographic variation, and significant gaps in delivering timely prenatal care, syphilis testing, and adequate treatment to pregnant women with syphilis were identified. The congenital syphilis prevention cascade is a useful tool to quantify programmatic successes and identify

What's New in Congenital Scoliosis?

PubMed

Pahys, Joshua M; Guille, James T

2018-03-01

Congenital scoliosis is a failure of vertebral formation, segmentation, or a combination of the 2 arising from abnormal vertebral development during weeks 4 to 6 of gestation. The associated spinal deformity can be of varying severity and result in a stable or progressive deformity based on the type and location of the anomalous vertebra(e). Bracing for congenital scoliosis is rarely indicated, while recent reports have demonstrated the utility of serial derotational casting for longer curves with multiple anomalous vertebrae as an effective "time buying strategy" to delay the need for surgery. Earlier hemivertebra excision and short-segment posterior spinal fusion have been advocated to prevent future curve progression of the deformity and/or the development of large compensatory curves. It has been shown in recent long-term follow-up studies that growth rates of the vertebral body and spinal canal are not as dramatically affected by pedicle screw instrumentation at a young age as once thought. Growth friendly surgery with either spine-based or rib-based anchors has demonstrated good results with curve correction while maintaining spinal growth. Rib-based anchors are typically more commonly indicated in the setting of chest wall abnormalities and/or when spinal anatomy precludes placement of spinal instrumentation. Recently, magnetically controlled growing rods have shown promising results in several studies that include a small subset of congenital scoliosis cases. A literature search was performed to identify existing studies related to the treatment of congenital scoliosis published from January 1, 2005 to June 1, 2016. Databases included PubMed, Medline, and the Cochrane Library. The search was limited to English articles and yielded 36 papers. This project was initiated by the Pediatric Orthopaedic Society of North America Publications Committee and was reviewed and approved by the Pediatric Orthopaedic Society of North America Presidential Line.

Congenital kyphoscoliosis (CKS) results from abnormal vertebral chondrification. Congenital fibrous bands occur in several locations with variable impact on vertebral development. We report a previously unreported case of a female infant with CKS presenting with an L2 hypoplastic vertebra and a costo-vertebral fibrous band extending to the skin in the form of a dimple. We also describe the therapeutic approach, consisting of surgical excision of the fibrous band and postoperative fulltime bracing, with a 7-year follow-up. We recommend a high index of suspicion in any unusual presentation of CKS and insist on case by case management in such cases.

Sodium mercaptoundecahydro-closo-dodecaborate (BSH) is being investigated clinically for BNCT. We examined the biodistribution of BSH and BPA administered jointly in different proportions in the hamster cheek pouch oral cancer model. The 3 assayed protocols were non-toxic, and showed preferential tumor boron uptake versus precancerous and normal tissue and therapeutic tumor boron concentration values (70–85 ppm). All 3 protocols warrant assessment in BNCT studies to contribute to the knowledge of (BSH+BPA)-BNCT radiobiology for head and neck cancer and optimize therapeutic efficacy.

We describe a previously unreported co-existence of retinitis pigmentosa and congenital toxoplasmosis. An eight year old male presented to our center with complaints of decreased night vision. Fundus evaluations in both the eyes demonstrated features typical of retinitis pigmentosa. There were well-defined punched out healed chorio-retinal scars suggestive of congenital toxoplasmosis. On the basis of history, clinical findings and reduction of a and b wave amplitudes on scotopic and photopic electroretinograph, a diagnosis of retinitis pigmentosa with congenital toxoplasmosis was made. Retinitis pigmentosa may co-exist with congenital toxoplasmosis that may affect the patient's overall ocular morbidity and visual acuity.

Congenital hearing loss (hearing loss present at birth) is one of the most prevalent chronic conditions in children. In the majority of developed countries, neonatal hearing-screening programmes enable early detection; early intervention will prevent delays in speech and language development and have long-lasting beneficial effects on social and emotional development and quality of life. A hearing loss diagnosis is usually followed by a search for an underlying aetiology. Congenital hearing loss might be attributed to environmental and prenatal factors, which prevail in low-income settings; congenital infections, particularly cytomegalovirus, are also a common risk factor for hearing loss. Genetic causes probably account for the majority of cases in developed countries; mutations can affect any component of the hearing pathway, in particular inner ear homeostasis (endolymph production and maintenance) and mechano-electrical transduction (conversion of a mechanical stimulus into electrochemical activity). Once the underlying cause of hearing loss is established, it might direct therapeutic decision-making and guide prevention and (genetic) counseling. Management options include specific antimicrobial therapies, surgical treatment of cranio-facial abnormalities and hearing aids. An improved understanding of the pathophysiology and molecular mechanisms underlying hearing loss and increased awareness of recent advances in genetic testing will promote the development of new treatment and screening strategies.

Congenital (spontaneous) intrahepatic portosystemic shunt is rare in the English literature. Most cases of portosystemic shunt occur after trauma, surgery, liver biopsy or as a result of chronic portal hypertension. Chronic shunting may result in encephalopathy, bleeding or hyperinsulinism. We report a case of an asymptomatic adult female with a presumed congenital intrahepatic portosystemic shunt and discuss the pertinent imaging findings and important key concepts related to this condition.

Management of Congenital Chest Wall Deformities

Congenital chest wall deformities are considered to be anomalies in chest wall growth. These can be categorized as either rib cage overgrowth or deformities related to inadequate growth (aplasia or dysplasia). Rib cage overgrowth leads to depression of the sternum (pectus excavatum) or protuberance of the sternum (pectus carinatum) and accounts for greater than 90% of congenital chest wall deformities. The remaining deformities are a result of inadequate growth. Evolution in the management of congenital chest wall deformities has made significant progress over the past 25 years. This article will review chest wall deformities and the current management strategies of these interesting anomalies. PMID:22294949

Colon Trauma: Evidence-Based Practices.

Colon injury is not uncommon and occurs in about a half of patients with penetrating hollow viscus injuries. Despite major advances in the operative management of penetrating colon wounds, there remains discussion regarding the appropriate treatment of destructive colon injuries, with a significant amount of scientific evidence supporting segmental resection with primary anastomosis in most patients without comorbidities or large transfusion requirement. Although literature is sparse concerning the management of blunt colon injuries, some studies have shown operative decision based on an algorithm originally defined for penetrating wounds should be considered in blunt colon injuries. The optimal management of colonic injuries in patients requiring damage control surgery (DCS) also remains controversial. Studies have recently reported that there is no increased risk compared with patients treated without DCS if fascial closure is completed on the first reoperation, or that a management algorithm for penetrating colon wounds is probably efficacious for colon injuries in the setting of DCS as well.

Congenital factor VII (FVII) deficiency is a rare bleeding disorder with autosomal recessive inheritance. The present female patient was diagnosed with congenital FVII deficiency because of low hepaplastin test (HPT), although vitamin K was given. Heterozygous p.A191T mutation was detected in the peripheral blood, and the same mutation was also found in the mother and sister. To the best of our knowledge, this is the fourth reported case of p.A191T mutation of FVII in the literature and the first to be reported in Japan. FVII coagulation activity (FVII:C) in asymptomatic heterozygous carriers is mildly reduced. Therefore, some patients may not be accurately diagnosed with congenital FVII deficiency. In infants with low HPT without vitamin K deficiency, congenital FVII deficiency should be considered. © 2015 Japan Pediatric Society.

Objective We investigated the prevalence of congenital renal and urologic anomalies in children with congenital hypothyroidism to determine whether further renal and urologic investigations would be of benefit. Study design Prevalence of congenital hypothyroidism was obtained from the New York State Congenital Malformation Registry. The occurrence of urinary tract anomalies were calculated for children with congenital hypothyroidism and compared to children without congenital hypothyroidism. In addition we obtained congenital hypothyroidism data from New York State newborn screening, and the cases were matched to Congenital Malformation Registry. Results Analysis of Congenital Malformation Registry data showed 980 children with congenital hypothyroidism and 3 661 585 children without congenital hypothyroidism born in New York State (1992-2005). Children with congenital hypothyroidism have a significantly increased risk of congenital renal and urological anomalies with the odds ratio (OR) of 13.2 (10.6-16.5). The other significantly increased defects in congenital hypothyroidism were cardiac, gastrointestinal, and skeletal. Analysis of matched data confirmed an increase of congenital renal and urologic anomalies with OR of 4.8 (3.7-6.3). Conclusions Children with congenital hypothyroidism have an increased prevalence of congenital renal and urologic anomalies. We suggest that these children should be evaluated for the presence of congenital renal and urologic anomalies with renal ultrasonography, and that further studies of common genes involved in thyroid and kidney development are warranted.

Since the creation of the Adult Congenital Heart Disease Units and of the High Obstetric Risk Units, there has been increasing interest in hemodynamic and obstetric outcomes in pregnant woman with congenital heart disease. Retrospective descriptive study of 56 women with congenital heart disease aged (mean [range]) 25 (18-40) years, who experienced a total of 84 pregnancies between January 1992 and August 2006. The women were divided into three pregnancy risk groups: A, low-risk; B, moderate-risk, and C, high-risk. The incidence of complications during pregnancy was 1.6%, 15%, and 20% in groups A, B, and C, respectively; the incidence during the puerperium was 2%, 23%, and 50%, respectively; and maternal mortality was 0%, 7.6%, and 25%, respectively. Overall, 69 children were born, and the prematurity rates in the three groups were 11%, 15%, and 100%, respectively. The following risk factors were studied: pulmonary hypertension, cyanosis, arrhythmia, left ventricular outflow tract obstruction, right ventricular dilatation, systemic right ventricle, and anticoagulation therapy. The risk factor most significantly associated with maternal or fetal morbidity or mortality was found to be pulmonary hypertension. Risk stratification in pregnant women with congenital heart disease provides prognostic information that can help multidisciplinary teams to target care to achieve the best results.

The aim of this paper is to address the dilemmas of the paediatric surgeon when facing an isolated, unilateral, congenital hydronephrosis and discuss the strategic options for the management of this condition. Congenital hydronephrosis, the most commonly diagnosed uropathy in children, is usually a benign and self-resolving condition. Nonobstructive hydronephrosis does not require operative treatment, while timely treatment is imperative for obstructive hydronephrosis before significant renal damage ensues. Managing congenital hydronephrosis is a challenging task. Thirty-two children with unilateral, isolated hydronephrosis and nonobstructed renography curves were followed up for 3 years. On the initial evaluation according to the grade of hydronephrosis: 22.6% were grade I, 54.8% grade II and 22.6% grade III. After 12 months of follow-up: 30% were grade I, 51 .5% grade II and 18.5% grade III, respectively. After the three-year follow-up, there were no hydroneproses greater than grade II. The mean value of the separate GFR of the affected kidney at initial evaluation was 42.83%, and 40.33% after three years. In three children the treatment was converted from conservative to surgical. Nonobstructive, congenital hydronephrosis is a benign condition not requiring any medical treatment, but aggressive observation is indicated.

Current mouse models for colorectal cancer often differ significantly from human colon cancer, being largely restricted to the small intestine. Here, we aim to develop a colon-specific inducible mouse model that can faithfully recapitulate human colon cancer initiation and progression. Carbonic anhydrase I (Car1) is a gene expressed uniquely in colonic epithelial cells. We generated a colon-specific inducible Car1 CreER knock-in (KI) mouse with broad Cre activity in epithelial cells of the proximal colon and cecum. Deletion of the tumor suppressor gene Apc using the Car1 CreER KI caused tumor formation in the cecum but did not yield adenomas in the proximal colon. Mutation of both Apc and Kras yielded microadenomas in both the cecum and the proximal colon, which progressed to macroadenomas with significant morbidity. Aggressive carcinomas with some invasion into lymph nodes developed upon combined induction of oncogenic mutations of Apc, Kras, p53, and Smad4 Importantly, no adenomas were observed in the small intestine. Additionally, we observed tumors from differentiated Car1-expressing cells with Apc/Kras mutations, suggesting that a top-down model of intestinal tumorigenesis can occur with multiple mutations. Our results establish the Car1 CreER KI as a valuable mouse model to study colon-specific tumorigenesis and metastasis as well as cancer-cell-of-origin questions.

Advancement in correction or palliation of congenital cardiac lesions has greatly improved the lifespan of congenital heart disease patients, resulting in a rapidly growing adult congenital heart disease (ACHD) population. As this group has increased in number and age, emerging science has highlighted the systemic nature of ACHD. Providers caring for these patients are tasked with long-term management of multiple neurologic, pulmonary, hepatic, renal, and endocrine manifestations that arise as syndromic associations with congenital heart defects or as sequelae of primary structural or hemodynamic abnormalities. In this review, we outline the current understanding and recent research into these extra-cardiac manifestations. Copyright © 2016 Elsevier Inc. All rights reserved.

2008-01-01

The aim of the article is to review the published scientific literature and epidemiological studies about the effect of selected environmental risk factors on congenital heart defects in infants. According to recent reports, the prevalence of congenital heart defects is around 1% of live births. Congenital heart malformations are the leading cause of infant mortality. Unfortunately, the majority of the causes of heart defects remain unknown. These malformations are caused by interaction of genetic and environmental factors. The article reviews selected environmental risk factors: maternal illnesses and conditions associated with metabolic disorder (maternal diabetes, obesity, phenylketonuria), maternal lifestyle factors (alcohol use, smoking), which may increase the risk of congenital heart defects.

Congenital hypothyroidism is the most common congenital endocrine disorder. The study aimed to determine the congenital hypothyroidism incidence by newborn screening programs in Henan Province, China. The screening programs for congenital hypothyroidism are based on the measurement of TSH in dried blood spots. The TSH concentration was measured in the dry blood spot specimen using a DELFIA fluoroimmunoassay. The TSH cutoff concentration was 8mU/l. The total coverage and the incidence of congenital hypothyroidism were 24.85% (5,142,148/20,694,441) and 0.37‰ (1992/5,142,148), respectively. The coverage and the incidence of CH were only 0.58% (4526/784,580) and 0.22‰ (1/4526) in 1997, respectively. However, the coverage and the incidence of CH were increased to 74.67% (1,203,278/1,611,582) and 0.32‰ (389/1,203,278). There were no significant differences in the number of congenital hypothyroidism between males and females (P>0.05). The number of congenital hypothyroidism was increased year after year. The newborn screening program for CH is successful and quite effective. Copyright © 2015 Elsevier B.V. All rights reserved.

Primary anorectoplasty in females with common anorectal malformations without colostomy.

The objective of this study is to assess the feasibility of primary posterior sagittal anorectoplasty in vestibular fistula without a covering colostomy. Girls presenting from July 1997 to July 2005 with vestibular fistula were included prospectively in the study, in a nonrandomized manner, after excluding those with megarectosigmoid and pouch colon. All underwent primary posterior sagittal anorectoplasty after total gut irrigation with normal saline. They were kept nil per oral until the fifth postoperative day. No patient was started on anal dilatation. Patients were assessed for immediate and delayed complications as well as voluntary bowel movements and continence. A total of 72 patients with an age range of 1.5 months to 8 years (median, 9 months) were studied after excluding 7 with pouch colon and 3 with megarectosigmoid. Of the 72, 3 had undergone previous surgery. Follow-up ranged from 7 months to 8 years. No wound dehiscence or recurrence of fistula was noted. There were 5 mild wound infections. At 1 month postoperative, all patients had 1 to 3 stools per day with no episodes of soiling. None required anal dilatations, laxatives, or enemas. Primary posterior sagittal anorectoplasty in vestibular fistula can be performed without a covering colostomy provided fecal contamination of the wound can be kept to the minimum in the first postoperative week. We achieve this by thorough total gut irrigation preoperatively and keeping the child nil per oral for the first 5 postoperative days. Continence rates are excellent and postoperative constipation is unlikely if megarectosigmoid and pouch colon are ruled out before surgery. Anal dilatation is not required after surgery.

Transverse loop colostomy and colonic motility.

The motility of the defunctionalized colon, distal to transverse loop colostomy, has never been studied "in vivo." The aim of our study was to evaluate the influence of transverse loop colostomy on colonic motility. Thirteen patients were examined before stoma closure by means of clinical evaluation and colonic manometry; we studied both the right and distal colon in both fasting and fed patients in order to detect motor activity. Quantitative and qualitative manometric analyses showed that the diverted colon had motor activity even if no regular colonic motor pattern was observed. The spreading of aboral propagated contractions (PCs) was sometimes recorded from the right colon to the distal colon. The response of the proximal and distal colon to a standard meal, when compared to fasting values, increased more than 40 and 35 %, respectively. Stool and gas ejections from the colostomy were never related to a particular type of colonic motility: Motor quiescence such as PCs was chaotically related to stool escape. In conclusion, motility of the defunctionalized colon is preserved in patients with transverse loop colostomy.

[Anatomy and pathogenesis of diverticular disease].

Wedel, T; Böttner, M

2014-04-01

Although diverticular disease is one of the most frequent gastrointestinal disorders the pathogenesis is not yet sufficiently clarified. The aim is to define the anatomy and pathogenesis of diverticular disease considering the risk factors and description of structural and functional alterations of the bowel wall. This article gives an appraisal of the literature, presentation and evaluation of classical etiological factors, analysis and discussion of novel pathogenetic concepts. Colonic diverticulosis is defined as an acquired out-pouching of multiple and initially asymptomatic pseudodiverticula through muscular gaps in the colon wall. Diverticular disease is characterized by diverticular bleeding and/or inflammatory processes (diverticulitis) with corresponding complications (e.g. abscess formation, fistula, covered and open perforation, peritonitis and stenosis). Risk factors for diverticular disease include increasing age, genetic predisposition, congenital connective tissue diseases, low fiber diet, high meat consumption and pronounced overweight. Alterations of connective tissue cause a weakening of preformed exit sites of diverticula and rigidity of the bowel wall with reduced flexibility. It is assumed that intestinal innervation disorders and structural alterations of the musculature induce abnormal contractile patterns with increased intraluminal pressure, thereby promoting the development of diverticula. Moreover, an increased release of pain-mediating neurotransmitters is considered to be responsible for persistent pain in chronic diverticular disease. According to the present data the pathogenesis of diverticular disease cannot be attributed to a single factor but should be considered as a multifactorial event.

The Adult Congenital Heart Association (ACHA) is dedicated to supporting patients with congenital heart disease. To guide patients to qualified providers and programs, it maintains a publicly accessible directory of dedicated adult congenital cardiac programs. We analyzed the directory in 2006 and 2015, aiming to evaluate the growth of the directory as a whole and to evaluate the growth of individual programs within the directory. We also hope this raises awareness of the growing opportunities that exist in adult congenital cardiology and cardiac surgery. Data in the directory are self-reported. Only data from US programs were collected and analyzed. By the end of 2015, compared to 2006, there were more programs reporting to the directory in more states (107 programs across 42 states vs 57 programs across 33 states), with higher overall clinical volume (591 vs 164 half-day clinics per week, 96,611 vs 34,446 patient visits). On average, each program was busier (5 vs 2 half-day clinics per week per program). Over the time period, the number of reported annual operations performed nearly doubled (4,346 operations by 210 surgeons vs 2,461 operations by 125 surgeons). Access to ancillary services including specific clinical diagnostic and therapeutic services also expanded. Between 2006 and 2015, the clinical directory and the individual programs have grown. Current directory data may provide benchmarks for staffing and services for newly emerging and existing programs. Verifying the accuracy of the information and inclusion of all programs will be important in the future.

Recurrent diverticulitis has been reported in up to 30% to 40% of patients who recover from an episode of colonic diverticular abscess, so elective interval resection is traditionally recommended. The aim of this study was to review the outcomes of patients who underwent percutaneous drainage of colonic diverticular abscess without subsequent operative intervention. This was an observational study. This investigation was conducted at a tertiary care academic medical center and a single-hospital health system. Patients treated for symptomatic colonic diverticular abscess from 2002 through 2007 were included. The primary outcomes measured were complications, recurrence, and colectomy-free survival. Two hundred eighteen patients underwent percutaneous drainage of colonic diverticular abscesses. Thirty-two patients (15%) did not undergo subsequent colonic resection. Abscess location was pelvic (n = 9) and paracolic (n = 23), the mean abscess size was 4.2 cm, and the median duration of percutaneous drainage was 20 days. The comorbidities of this group of patients included severe cardiac disease (n = 16), immunodeficiency (n = 7), and severe pulmonary disease (n = 6). Freedom from recurrence at 7.4 years was 0.58 (95% CI 0.42-0.73). All recurrences were managed nonoperatively. Recurrence was significantly associated with an abscess size larger than 5 cm. Colectomy-free survival at 7.4 years was 0.17 (95% CI 0.13-0.21). This study was limited by its retrospective, nonexperimental design and short follow-up. In selected patients, observation after percutaneous drainage of colonic diverticular abscess appears to be a safe and low-risk management option.

Angle closure glaucoma in congenital ectropion uvea.

Congenital ectropion uvea is a rare anomaly, which is associated with open, but dysplastic iridocorneal angles that cause childhood glaucoma. Herein, we present 3 cases of angle-closure glaucoma in children with congenital ectropion uvea. Three children were initially diagnosed with unilateral glaucoma secondary to congenital ectropion uvea at 7, 8 and 13 years of age. The three cases showed 360° of ectropion uvea and iris stromal atrophy in the affected eye. In one case, we have photographic documentation of progression to complete angle closure, which necessitated placement of a glaucoma drainage device 3 years after combined trabeculotomy and trabeculectomy. The 2 other cases, which presented as complete angle closure, also underwent glaucoma drainage device implantation. All three cases had early glaucoma drainage device encapsulation (within 4 months) and required additional surgery (cycloablation or trabeculectomy). Congenital ectropion uvea can be associated with angle-closure glaucoma, and placement of glaucoma drainage devices in all 3 of our cases showed early failure due to plate encapsulation. Glaucoma in congenital ectropion uvea requires attention to angle configuration and often requires multiple surgeries to obtain intraocular pressure control.

Two infants with congenital toxoplasmosis are presented. A girl born prematurely was treated postnatally after the mother had received antimicrobial treatment during pregnancy for acute toxoplasmosis. Apart from being small for gestational age, she remained without symptoms and treatment was ceased after 13 months. A 2-month-old boy presented with hydrocephalus and chorioretinitis, consistent with congenital toxoplasmosis. Despite antimicrobial treatment, at 12 months of age he suffered from epilepsy, cerebral palsy and vision impairment. Most infants with congenital toxoplasmosis (2 per 1000 live births in the Netherlands) are asymptomatic at birth. The education of pregnant women is crucial for the prevention of congenital toxoplasmosis. Awareness of antenatal and postnatal presenting signs and symptoms is important for clinicians, because early diagnosis and treatment may minimize sequelae. Untreated, the majority of affected infants will develop chorioretinitis, deafness and/or neurological symptoms.

OBJECTIVE To emphasize the need of an accurate diagnosis of congenital esophageal stenosis due to tracheobronchial remnants, since its treatment differs from other types of congenital narrowing. CASE DESCRIPTION Four cases of lower congenital esophageal stenosis due to tracheobronchial remnants, whose definitive diagnosis was made by histopathology. Except for the last case, in which a concomitant anti-reflux surgery was not performed, all had a favorable outcome after resection and anastomosis of the esophagus. COMMENTS The congenital esophageal stenosis is an intrinsic narrowing of the organ's wall associated with its structural malformation. The condition can be caused by tracheobronchial remnants, fibromuscular stenosis or membranous diaphragm and the first symptom is dysphagia after the introduction of solid food in the diet. The first-choice treatment to tracheobronchial remnants cases is the surgical resection and end-to-end anastomosis of the esophagus.

Congenital toxoplasmosis is considered a rare but potentially severe infection. Prenatal education about congenital toxoplasmosis could be the most efficient and least harmful intervention, yet its effectiveness is uncertain. To assess the effects of prenatal education for preventing congenital toxoplasmosis. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (15 January 2012), PubMed (1966 to 15 January 2012), EMBASE (1980 to 15 January 2012), CINAHL (1982 to 15 January 2012), LILACS (1982 to 15 January 2012), IMEMR (1984 to 15 January 2012), and reference lists of relevant papers, reviews and websites. Randomized and quasi-randomized controlled trials (RCTs) of all types of prenatal education on toxoplasmosis infection during pregnancy. Cluster-randomized trials were included. Two review authors independently assessed trials for inclusion and study quality. Two review authors extracted data. Data were checked for accuracy. Two cluster-randomized controlled trials (involving a total of 5455 women) met the inclusion criteria. The two included trials measured the effectiveness of the intervention in different ways which meant that meta-analysis of the results was not possible One trial (432 women enrolled) conducted in Canada was judged of low methodological quality. The authors did not report measure of association but only provided P values (P less than 0.05) for all outcomes. Moreover, losses to follow-up were high (34%, 147 out of 432 women initially enrolled). The authors concluded that prenatal education can effectively change pregnant women's behavior as it increased pet, personal and food hygiene. The second trial conducted in France was also judged of low methodological quality. Losses to follow-up were high (44.5%, 2233 out of 5023 women initially enrolled) and differential (40% in the intervention group and 52% in the control group). The authors concluded that prenatal education for congenital toxoplasmoses has a significant effect

A twin study of congenital hemiplegia.

PubMed

Goodman, R; Alberman, E

1996-01-01

Twins were more than three times more common in a large sample of London children with congenital hemiplegia than in the general population. This over-representation of twins could largely be explained by their higher rate of preterm birth, though twin-specific risk factors, including the consequences of a co-twin's death in utero, may also have played a part. None of the 34 co-twins who survived infancy had hemiplegia or any other form of cerebral palsy. Among 155 siblings of singletons with congenital hemiplegia, no child had hemiplegia and only one had cerebral palsy. Perhaps it is chance rather then genetic liability or an adverse environment that primarily governs who does and does not become congenitally hemiplegic.

Acute infection of toxoplasmosis during pregnancy is detrimental to the developing fetus. In the United States, approximately 1 in 10,000 live births are affected by congenital toxoplasmosis. Although multifactorial in etiology, maternal infection is primarily attributed to the consumption of contaminated meat or water. Infection and transmission to the fetus may result in devastating neurologic impairment. Screening methods for all pregnant women should be implemented in routine prenatal care. This article will highlight the inherent dangers of congenital toxoplasmosis, while including general care of the fetus for prevention of transmission, medical management, and long-term outcomes.

Congenital anomalies that are diagnosed in at least 120,000 US infants every year are the leading cause of infant death and contribute to disability and pediatric hospitalizations. Several large-scale epidemiologic studies have provided substantial evidence of an association between congenital anomalies and cancer risk in children, suggesting potential underlying cancer-predisposing conditions and the involvement of developmental genetic pathways. Electronic medical records from 1,107 pediatric, adolescent, and young adult oncology patients were reviewed. The observed number (O) of congenital anomalies among children with a specific pediatric cancer subtype was compared to the expected number (E) of anomalies based on the frequency of congenital anomalies in the entire study population. The O/E ratios were tested for significance using Fisher's exact test. The Kaplan-Meier method was used to compare overall and neurological malignancy survival rates following tumor diagnosis. Thirteen percent of patients had a congenital anomaly diagnosis prior to their cancer diagnosis. When stratified by congenital anomaly subtype, there was an excess of neurological anomalies among children with central nervous system tumors (O/E = 1.56, 95%CI 1.13-2.09). Male pediatric cancer patients were more likely than females to have a congenital anomaly, particularly those <5 years of age (O/E 1.35, 95%CI 0.97-1.82). Our study provides additional insight into the association between specific congenital anomaly types and pediatric cancer development. Moreover, it may help to inform the development of new screening policies and support hypothesis-driven research investigating mechanisms underlying tumor predisposition in children with congenital anomalies. © 2017 The Authors.

This study investigated the inhibitory effect of vitamin D-binding protein-derived macrophage-activating factor (GcMAF) on carcinogenesis and tumor growth, using a 9,10-dimethyl-1,2-benzanthracene (DMBA)-induced hamster cheek pouch carcinogenesis model, as well as the cytocidal effect of activated macrophages against HCPC-1, a cell line established from DMBA-induced cheek pouch carcinoma. DMBA application induced squamous cell carcinoma in all 15 hamsters of the control group at approximately 10 weeks, and all 15 hamsters died of tumor burden within 20 weeks. By contrast, 2 out of the 14 hamsters with GcMAF administration did not develop tumors and the remaining 12 hamsters showed a significant delay of tumor development for approximately 3.5 weeks. The growth of tumors formed was significantly suppressed and none of the hamsters died within the 20 weeks during which they were observed. When GcMAF administration was stopped at the 13th week of the experiment in 4 out of the 14 hamsters in the GcMAF-treated group, tumor growth was promoted, but none of the mice died within the 20-week period. On the other hand, when GcMAF administration was commenced after the 13th week in 5 out of the 15 hamsters in the control group, tumor growth was slightly suppressed and all 15 hamsters died of tumor burden. However, the mean survival time was significantly extended. GcMAF treatment activated peritoneal macrophages in vitro and in vivo, and these activated macrophages exhibited a marked cytocidal effect on HCPC-1 cells. Furthermore, the cytocidal effect of activated macrophages was enhanced by the addition of tumor-bearing hamster serum. These findings indicated that GcMAF possesses an inhibitory effect on tumor development and growth in a DMBA-induced hamster cheek pouch carcinogenesis model.

In accordance with the goals of the World Health Organization Regional Committee for Europe, the Italian national Measles and Rubella Elimination Plan 2010-2015 aimed to reduce the incidence of congenital rubella cases to <1 case/100,000 live births by 2015. In Italy, a passive national surveillance system for congenital rubella and rubella in pregnancy is active since 2005. We estimated the degree of underreporting of congenital rubella, performing a capture-recapture analysis of cases detected through two independent sources: the national surveillance system and the national hospital discharge database, in the years 2010-2014. We found that 6 out of 11 cases tracked in the retrospective case-finding from hospital registries had not been notified to the surveillance system, and we estimated a degree of underreporting of 53% for the period 2010-2014. This approach showed to be simple to perform, repeatable, and effective. In order to reduce underreporting, some actions aimed at strengthening surveillance procedures are needed. The adoption on a routine basis of the review of hospital discharge registries for case-finding, monthly zero-reporting, and actions to train and sensitize all the specialists involved in the care of pregnant women and the newborns to notification procedures are recommended. What is Known • In Italy, the incidence of congenital rubella was below the WHO target of 1/100,000 live births in 2005-2015, except for two peaks in 2008 and 2012 (5 and 4/100,000, respectively). • Further efforts are required to improve congenital rubella surveillance so that it is more sensitive and specific. The WHO proposes retrospective case-finding from hospital records as an alternative approach to detect infants with congenital rubella. What is New • Underreporting of congenital rubella in Italy was 53% in 2010-2014. • Hospital discharge registries resulted to be an appropriate source to detect congenital rubella cases.

Congenital radioulnar synostosis is a rare malformation of the upper limb, with functional limitations of the limb. A 10-year-old child with pain and restricted mobility of the elbow joint was admitted to the hospital. Plain film radiography and CT examination was performed. Radiological examinations showed a congenital radioulnar synostosis. The child underwent surgical treatment - derotational osteotomy. Diagnostic imaging including computed tomography with three-dimentional (3D) reconstructions, preceding surgery enables planning of the surgical treatment.

Inherited congenital bilateral atresia of the external auditory canal, congenital bilateral vertical talus and increased interocular distance.

PubMed

Rasmussen, N; Johnsen, N J; Thomsen, J

1979-01-01

Six out of twenty descendants of a reportedly affected grandfather have congenital bilateral symmetrical and isolated subtotal atresia of the external auditory canal. Four of the six affected descendants have bilateral foot anomalies--two affected cousins having congenital vertical talus. All of the three affected boys in the third generation have increased interocular distance. Short fifth fingers, bilateral single transverse palmar creases, pyloric stenosis and congenital exotropia were found infrequently and are considered coincidental features. Apart from the atresia, oto-rhinolaryngologic examination, mental function, dermatoglyphics, IgA, kidney function and heart function of the affected descendants were all normal. The karyotype of four affected descendants examined was normal. An autosomal dominant inheritance with variable expressivity is suggested.

Anti-inflammatory effects of Houttuynia cordata supercritical extract (HSE) were investigated in rat carrageenan-air pouch model. Oral administration of HSE (50-200 mg/kg) suppressed carrageenan-induced exudation and albumin leakage, as well as inflammatory cell infiltration at a high dose (200 mg/kg). Intraperitoneal injection of dexamethasone (2 mg/kg) only decreased exudation and cell infiltration, while indomethacin (2 mg/kg, i.p.) reduced exudate volume and albumin content without influence on the cell number. HSE lowered tumor-necrosis factor-α (TNF-α) and nitric oxide (NO), as well as prostaglandin E2 (PGE2). Dexamethasone only reduced TNF-α and NO, while indomethacin decreased PGE2. The results indicate that HSE exhibits anti-inflammatory effects by inhibiting both TNF-α-NO and cyclooxygenase-2-PGE2 pathways. PMID:22787488

To assess the extent to which the increased risk of congenital abnormalities seen in women with pre-gestational insulin-treated diabetes mellitus is unspecific or related to the embryology of specific organs. Cases with congenital abnormalities were identified in the population-based Hungarian Congenital Abnormality Registry from 1980 to 1996 with two newborn children without congenital abnormality selected from the National Birth Registry as controls. We adjusted for parity, maternal age, and use of antipsychotic drugs. Among cases we found 63/22,843 babies with maternal diabetes compared with 50/38,151 in the control group [adjusted prevalence odds ratio (POR) 2.1; 95% CI 1.5-3.1]. The association was strongest for the following congenital abnormalities: renal agenesis (POR: 14.8; 95% CI, 3.5-62.1), obstructive congenital abnormalities of the urinary tract (POR: 4.3; 95% CI, 1.3-13.9), cardiovascular congenital abnormalities (POR: 3.4; 95% CI, 2.0-5.7), and multiple congenital abnormalities (POR: 5.0; 95% CI, 2.4-10.2). These data indicate that pre-gestational maternal diabetes is associated with strong teratogenic effects on the kidney, urinary tract, and heart, and strongly associated with multiple congenital abnormalities. We found no material association between diabetes and spinal congenital abnormalities and limb deficiencies.

The clinical anatomy of congenital portosystemic venous shunts.

PubMed

Stringer, Mark D

2008-03-01

Congenital portosystemic venous shunts are rare. Their gross anatomy has not been well defined. Four different varieties of congenital portosystemic venous shunts are described in six children seen during a 10-year period, focusing on the anatomy of the shunt as determined by imaging studies and surgery. A detailed review of the literature indicates that congenital portosystemic venous shunts are best classified as: extrahepatic or intrahepatic. Extrahepatic shunts may be further subdivided into portocaval shunts (type 1 end-to-side and type 2 side-to-side) and others. Intrahepatic shunts are due to an abnormal intrahepatic connection between the portal vein and hepatic vein/inferior vena cava or a persistent patent ductus venosus. Additional congenital anomalies, particularly cardiac malformations, may be associated with any type. Some congenital intrahepatic portosystemic venous shunts close spontaneously in infancy; all other congenital portosystemic venous shunts tend to remain patent. To a variable extent, depending largely on the volume and duration of the shunt, affected individuals are at risk of developing hepatic encephalopathy and/or an intrahepatic tumor. The key to understanding the pathogenesis of these shunts lies in the normal developmental mechanisms underlying the formation of the portal vein and inferior vena cava in the embryo.

OBJECTIVE To emphasize the need of an accurate diagnosis of congenital esophageal stenosis due to tracheobronchial remnants, since its treatment differs from other types of congenital narrowing. CASE DESCRIPTION Four cases of lower congenital esophageal stenosis due to tracheobronchial remnants, whose definitive diagnosis was made by histopathology. Except for the last case, in which a concomitant anti-reflux surgery was not performed, all had a favorable outcome after resection and anastomosis of the esophagus. COMMENTS The congenital esophageal stenosis is an intrinsic narrowing of the organâ€(tm)s wall associated with its structural malformation. The condition can be caused by tracheobronchial remnants, fibromuscular stenosis or membranous diaphragm and the first symptom is dysphagia after the introduction of solid food in the diet. The first-choice treatment to tracheobronchial remnants cases is the surgical resection and end-to-end anastomosis of the esophagus. PMID:24142326

Anorectal malformations (ARM) are common congenital anomalies seen throughout the world. Comparison of outcome data has been hindered because of confusion related to classification and assessment systems. The goals of the Krinkenbeck Conference on ARM was to develop standards for an International Classification of ARM based on a modification of fistula type and adding rare and regional variants, and design a system for comparable follow up studies. Lesions were classified into major clinical groups based on the fistula location (perineal, recto-urethral, recto-vesical, vestibular), cloacal lesions, those with no fistula and anal stenosis. Rare and regional variants included pouch colon, rectal atresia or stenosis, rectovaginal fistula, H-fistula and others. Groups would be analyzed according to the type of procedure performed stratified for confounding associated conditions such as sacral anomalies and tethered cord. A standard method for postoperative assessment of continence was determined. A new International diagnostic classification system, operative groupings and a method of postoperative assessment of continence was developed by consensus of a large contingent of participants experienced in the management of patients with ARM. These methods should allow for a common standardization of diagnosis and comparing postoperative results.

Congenital syphilis is preventable and curable if maternal infection is detected early, and pregnant women in Korea are screened routinely for this disease. Nevertheless, the incidence of congenital syphilis is not decreasing. Prenatal diagnosis of congenital syphilis is difficult and treatment is usually based on maternal syphilis serology. Prenatal ultrasonographic examination may sometimes reveal abnormal features suggesting congenital infection. The authors report a case of congenital syphilis that was diagnosed in both fetus and asymptomatic mother following detection on prenatal ultrasonography of transient fetal pleural effusion. The case is noteworthy for its sonographic presentation as fetal pleural effusion rapidly resolved spontaneously.

Evolving colon injury management: a review.

Greer, Lauren T; Gillern, Suzanne M; Vertrees, Amy E

2013-02-01

The colon is the second most commonly injured intra-abdominal organ in penetrating trauma. Management of traumatic colon injuries has evolved significantly over the past 200 years. Traumatic colon injuries can have a wide spectrum of severity, presentation, and management options. There is strong evidence that most non-destructive colon injuries can be successfully managed with primary repair or primary anastomosis. The management of destructive colon injuries remains controversial with most favoring resection with primary anastomosis and others favor colonic diversion in specific circumstances. The historical management of traumatic colon injuries, common mechanisms of injury, demographics, presentation, assessment, diagnosis, management, and complications of traumatic colon injuries both in civilian and military practice are reviewed. The damage control revolution has added another layer of complexity to management with continued controversy.

Carotenoids have numerous biological properties that may underpin a role for them as chemopreventive agents. However, except for beta-carotene, little is known about how dietary carotenoids are associated with common cancers, including colon cancer. The objective of this study was to evaluate associations between dietary alpha-carotene, beta-carotene, lycopene, lutein, zeaxanthin, and beta-cryptoxanthin and the risk of colon cancer. Data were collected from 1993 case subjects with first primary incident adenocarcinoma of the colon and from 2410 population-based control subjects. Dietary data were collected from a detailed diet-history questionnaire and nutrient values for dietary carotenoids were obtained from the US Department of Agriculture-Nutrition Coordinating Center carotenoid database (1998 updated version). Lutein was inversely associated with colon cancer in both men and women [odds ratio (OR) for upper quintile of intake relative to lowest quintile of intake: 0.83; 95% CI: 0.66, 1.04; P = 0.04 for linear trend]. The greatest inverse association was observed among subjects in whom colon cancer was diagnosed when they were young (OR: 0.66; 95% CI: 0.48, 0.92; P = 0.02 for linear trend) and among those with tumors located in the proximal segment of the colon (OR: 0.65; 95% CI: 0.51, 0.91; P < 0.01 for linear trend). The associations with other carotenoids were unremarkable. The major dietary sources of lutein in subjects with colon cancer and in control subjects were spinach, broccoli, lettuce, tomatoes, oranges and orange juice, carrots, celery, and greens. These data suggest that incorporating these foods into the diet may help reduce the risk of developing colon cancer.

Restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis (IPAA) is the most frequently performed operation for intractable ulcerative colitis (UC) and for many patients with familial adenomatous polyposis (FAP). It can be complicated by a functional evacuation difficulty, which is not well understood. We aimed to evaluate the role of defaecating pouchography in an attempt to assess the mechanism of evacuation difficulty in pouch patients. All RPC patients who had had a defaecating pouchogram for evacuation difficulty at one hospital between 2006 and 2014 were retrospectively reviewed. The findings and features were correlated with the symptoms. Demographic, clinical and radiological variables were analysed. Eighty-seven [55 (63%) female] patients aged 47.6 ± 12.5 years (mean standard ± SD) were identified. Thirty-five had a mechanical outlet obstruction and 52 had no identified mechanical cause to explain the evacuation difficulty. The mean age of these 52 [33 (63%) female] patients was 48.2 ± 13 years. Of these 52 patients, significantly more used anti-diarrhoeal medication (P = 0.029), complained of a high frequency of defaecation (P = 0.005), experienced a longer time to the initiation of defaecation (P = 0.049) and underwent pouchoscopy (P = 0.003). Biofeedback appeared to improve the symptoms in 7 of 16 patients with a nonmechanical defaecatory difficulty. The most common findings on defaecating pouchography included residual barium of more than 33% after an attempted evacuation (46%, n = 24), slow evacuation (35%, n = 18) and mucosal irregularity (33%, n = 17). Correlation between radiological features and symptoms showed a statistically significant relationship between straining, anal pain, incontinence and urgency with patterns of anismus or pelvic floor descent or weakness seen on the defaecating pouchogram. Symptoms of incomplete evacuation, difficulty in the initiation of defaecation, high defaecatory frequency and

Case Presentations. The authors present two case reports of a congenital extrahepatic portosystemic shunt (Type II). In the first patient, apparently nonspecific symptoms, such as headache and fatigue, proved to be secondary to hypoglycemic episodes related to the presence of a portosystemic shunt, later confirmed on imaging. During portal vein angiography, endovascular embolization of the portocaval fistula achieved occlusion of the anomalous venous tract. In the second patient, affected by Down's syndrome, the diagnosis of a portosystemic malformation was made by routine ultrasonography, performed to rule out concurrent congenital anomalies. Because of the absence of symptoms, we chose to observe this patient. Conclusions. These two case reports demonstrate the clinical heterogeneity of this malformation and the need for a multidisciplinary approach. As part of a proper workup, clinical evaluation must always be followed by radiographic diagnosis.

Congenital toxoplasmosis is considered a rare but potentially severe infection. Prenatal education about congenital toxoplasmosis could be the most efficient and least harmful intervention, yet its effectiveness is uncertain. To assess the effects of prenatal education for preventing congenital toxoplasmosis. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 May 2015), and reference lists of relevant papers, reviews and websites. Randomized and quasi-randomized controlled trials of all types of prenatal education on toxoplasmosis infection during pregnancy. Cluster-randomized trials were eligible for inclusion. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Two cluster-randomized controlled trials (RCTs) (involving a total of 5455 women) met the inclusion criteria. The two included trials measured the effectiveness of the intervention in different ways, which meant that meta-analysis of the results was not possible. The overall quality of the two studies, as assessed using the GRADE approach, was low, with high risk of detection and attrition bias in both included trials.One trial (432 women enrolled) conducted in Canada was judged of low methodological quality. This trial did not report on any of the review's pre-specified primary outcomes and the secondary outcomes reported results only as P values. Moreover, losses to follow-up were high (34%, 147 out of 432 women initially enrolled). The authors concluded that prenatal education can effectively change pregnant women's behavior as it increased pet, personal and food hygiene. The second trial conducted in France was also judged of low methodological quality. Losses to follow-up were also high (44.5%, 2233 out of 5023 women initially enrolled) and differential (40% in the intervention group and 52% in the control group). The authors concluded that prenatal education for congenital toxoplasmoses has a

Congenital anophthalmia: current concepts in management.

Quaranta-Leoni, Francesco M

2011-09-01

The introduction of hydrogel socket and orbital expanders has modified the approach towards the rehabilitation of congenital anophthalmia. This study highlights the most recent advances for the treatment of congenital anophthalmia based on personal experience and the review of recent literature. Hydrogel socket expanders may be positioned as an out-patient procedure with topical anaesthesia, using cyanoacrylate glue as opposed to temporary tarsorraphy. Increased orbital volume has been confirmed by computed tomography (CT) scan or magnetic resonance imaging (MRI) following early dermis-fat graft in children with congenital anophthalmia. An orbital tissue expander made of an inflatable silicone globe sliding on a titanium T-plate and secured to the lateral orbital rim appears to be effective to stimulate orbital bone growth and development. Congenital anophthalmia has a complex cause with both genetic and environmental factors involved. The ideal treatment is simultaneous expansion of the eyelids, socket and orbital bones, and it should begin after birth as soon as possible. Socket expansion with self-inflating expanders is a useful technique, although custom-made conformers may produce similar results. Dermis-fat grafts are another reasonable option as an orbital implant, following adequate lid and socket expansion.

This study sets out to demonstrate the normal developmental steps of the tegmen tympani and thus explains the typical localization of congenital tegmental defects. For this study, 79 macerated and formalin-fixed human temporal bones from 14th fetal week to adults were observed and prepared. Macroscopic and microscopic examination of the prenatal and postnatal changes of the tegmen tympani during its development. Temporal bones from 14th fetal week to adults underwent descriptive anatomic studies to understand the normal development of the tegmen tympani and to find a possible cause of its congenital defects. The medial part of the tegmen tympani develops from the otic capsule during chondral ossification, thus forming the tegmental process of the petrous part. The lateral part shows membranous ossification. The tegmental process cases a temporary bony dehiscence lateral to the geniculate ganglion between the 23rd and 25th fetal week. Congenital defects develop near the geniculate ganglion and seem to be due to an incomplete development of tegmental process of otic capsule. Because of that, congenital lesion of the tegmen tympani can be defined as an inner ear defect.

The purpose was to determine the normal distribution of distended colon volumes as a guide for rectal contrast material administration protocols. All computed tomography colonography studies performed at Emory University Hospital, Atlanta, Georgia, between January 2009 and January 2015, were reviewed retrospectively. In total, 85 subjects were included in the analysis (64% [54 of 85] female and 36% [31 of 85] male). Mean patient age was 65 years (range: 42-86y). Distended colon volumes were determined from colon length and transaxial diameter measurements made using a 3-dimensional workstation. Age, sex, race, height, weight, and body mass index were recorded. The normal distributions of distended colon volumes and lengths were determined. Correlations between colonic volume and colonic length, and demographic variables were assessed. Mean colon volume was 2.1L (range: 0.7-4.4L). Nearly, 17% of patients had a distended colonic volume of >3L. Mean colon length was 197cm (range: 118-285cm). A weak negative correlation was found between age and colonic volume (r = -0.221; P = 0.04). A weak positive correlation was found between body mass index and colonic length (r = 0.368; P = 0.007). Otherwise, no significant correlations were found for distended colonic volume or length and demographic variables. In conclusion, an average of approximately 2L of contrast material may be necessary to achieve full colonic opacification. This volume is larger than previously reported volumes (0.8-1.5L) for rectal contrast material administration protocols. Copyright © 2015 Mosby, Inc. All rights reserved.

Congenital absent digits continue to be described by many confusing terms and are currently classified in categories I, V, and VI of the International Federation of Societies for Surgery of the Hand classification and seven subclassification systems. Very few classification systems provide any logical basis for surgical reconstruction. The purpose of this study was to develop a simple alphanumerical documentation system to reproducibly describe the morphological or radiographic appearance of congenital absent digits and facilitate communication of these childrens' hand anomalies from one hand surgeon to another. Dorsal and palmar photographs and PA radiographs of 235 hands in 204 children born with congenital absent digits over a 15-year period were analyzed to determine which digital rays were missing and their level of absence. Each hand can be described by three letters, R (radial), C (central), and U (ulnar), as well as numbers 1-5. The first letter and number designate which rays are missing and the second and third letters and numbers designate which rays remain present. There are 15 morphological phenotypes of congenital absent digits. The three most common phenotypes are U4R1 (a thumb but absence of all four fingers), R1U4 (absent thumb), and R5 (aplastic hand). This new documentation system allows hand surgeons to describe the simple morphological or radiographic appearance of congenital absent digits; incorporates all the previous subclassification systems that have attempted to describe congenital absent digits in radial, central, and ulnar deficiencies, symbrachydactyly, and congenital constriction ring syndrome; and has subsequently allowed the development of an algorithm which predicts whether conventional or microsurgical reconstruction is indicated for each specific phenotype.

The objective of this study is comparing colon diversion versus primary repair in penetrating colon gunshot injuries. A retrospective study of 63 cases of gunshot abdomen with penetrating colon injury were admitted to Al-jalla Hospital in 2011 in Benghazi, Libya. After surgical intervention, these patients were observed for any postoperative complications. During the study period, 63 eligible patients included, 62 (98.4%) were males and 1 (1.6%) was female. And the mean age was 29.24 years. Eighteen patients had an injury on the right side of the colon, while 16, 6, 11, 6, 2, 3, and 1 patients had an injury on the transverse, left, sigmoid, rectum, right transverse, left transverse, and total colonic injury, respectively. In the first group, 23 patients (36.5%) was treated with colon diversion, (2 with Hartmann's operation, 21 with loop colostomy). In the second group, 40 patients (63.4 %) was treated with primary repair. Eighteen (28.5%) with right hemicolectomy, 5 (7.9%) with transverse colon resection and anastomosis, and 17 (26.9%) with simple repair. We evaluate the rate of postoperative complication and compare the postoperative morbidity between both groups. In our study, there was no significant statistical difference between types of operations and rate of complications (P = 0.18). We could not see any advantage of the diversion over the primary repair. To reduce risk of the psychological trauma, complications of colostomy, unnecessary repeated hospitalization, decrease of economic cost, and complications of stoma revision operation, we should consider that the primary repair of penetrating colon injuries is an acceptable alternative method of treatment over the colostomy.

Over the past decade, amniotic fluid-derived stem cells have emerged as a novel, experimental approach for the treatment of a wide variety of congenital anomalies diagnosed either in utero or postnatally. There are a number of unique properties of amniotic fluid stem cells that have allowed it to become a major research focus. These include the relative ease of accessing amniotic fluid cells in a minimally invasive fashion by amniocentesis as well as the relatively rich population of progenitor cells obtained from a small aliquot of fluid. Mesenchymal stem cells, c-kit positive stem cells, as well as induced pluripotent stem cells have all been derived from human amniotic fluid in recent years. This article gives a pediatric surgeon’s perspective on amniotic fluid stem cell therapy for the management of congenital anomalies. The current status in the use of amniotic fluid-derived stem cells, particularly as they relate as substrates in tissue engineering-based applications, is described in various animal models. A roadmap for further study and eventual clinical application is also proposed. PMID:22986340

Context: Congenital glaucoma is a potentially blinding ocular disease of the childhood. Identification of the possible associated risk factors and may be helpful for prevention or early detection of this public health problem. Aims: To demonstrate the demographic features of congenital glaucoma subjects. Setting and Design: The charts of congenital glaucoma patients referred to Tamcelik Glaucoma Center were retrospectively reviewed through the dates of 2000 and 2013. Materials and Methods: Analyzed data included diagnosis, age at first presentation, symptoms at first presentation, laterality of the disease, sex, presence of consanguinity, family history of congenital glaucoma, maturity of the fetus at delivery, and maternal age at conception. Statistical Analysis Used: Statistical Package for Social Sciences (SPSS) version 19.0 by IBM (SPSS Inc, Chicago, Illinois, USA) was used to compare the mean of continuous variables with Student's t-test and analysis of variance (ANOVA) and χ2 test was used to test differences in proportions of categorical variables. Results: The data of 600 eyes of 311 patients were analyzed. The distribution of primary and secondary congenital glaucoma among the patients were 63.3% (n = 197) and 36.7% (n = 114), respectively. Of the 311 patients, 57.2% (n = 178) were male and 42.8% (n = 133) were female. The overall frequency of bilateral disease was 92.3% (n = 287). Overall rate of consanguinity and positive family history was 45.3% (n = 141) and 21.2% (n = 66), respectively. Conclusions: Bilateral disease in this study was more common than previously reported studies. Positive family history was more frequent in primary congenital glaucoma although not statistically significant. PMID:24881602

Congenital cytomegalovirus (CMV) infection is the second most frequent cause of mental retardation and sensorineural hearing loss, after genetic factors. Recently, pediatric forensic and fetopathological studies have led to progress in understanding the pathophysiological mechanisms underlying the various neurosensory sequelae. Thanks to the identification of certain prognostic factors of hearing loss, therapeutic protocols based on antiviral molecules are now proposed for target populations. This treatment has shown efficacy in limiting hearing threshold deterioration and even, in some cases, seems to provide partial recovery of hearing in symptomatic congenitally infected CMV neonates. However, optimal treatment duration and administration modalities are not clearly defined. This article reviews recent data concerning audiovestibular sequelae and their management in children congenitally infected by CMV. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Deprivation amblyopia and congenital hereditary cataract.

Amblyopia is a neurodevelopmental disorder of vision associated with decreased visual acuity, poor or absent stereopsis, and suppression of information from one eye.(1,2) Amblyopia may be caused by strabismus (strabismic amblyopia), refractive error (anisometropic amblyopia), or deprivation from obstructed vision (deprivation amblyopia). 1 In the developed world, amblyopia is the most common cause of childhood visual impairment, 3 which reduces quality of life 4 and also almost doubles the lifetime risk of legal blindness.(5, 6) Successful treatment of amblyopia greatly depends on early detection and treatment of predisposing disorders such as congenital cataract, which is the most common cause of deprivational amblyopia. Understanding the genetic causes of congenital cataract leads to more effective screening tests, early detection and treatment of infants and children who are at high risk for hereditary congenital cataract.

Familial Adenomatous Polyposis (FAP) is an autosomal dominant condition giving rise to multiple adenomatous polyps in the colon which invariably become malignant by the fourth decade. Congenital hypertrophy of retinal pigment epithelium (CHRPE) is one of its extra intestinal manifestations early in childhood seen, present in 90% of FAP population and is easy to detect. Patients diagnosed with FAP and at risk first degree family members were screened for CHRPE using a slit lamp and indirect ophthalmoscopy. The retina of 17 diagnosed FAP patients and 13 individuals at risk were examined. The site and size of CHRPE lesions were documented. Thirteen (76%) of 17 FAP patients (male-10, female - 7, median age - 30 years; range 15-55 years) had CHRPE lesions; seven (54%) had bilateral CHRPE lesions and six (46%) had unilateral lesions. A single lesion was detected in 6 (46%) while 7 (54%) patients had multiple lesions. Of 13 at risk individuals (7- male, female-6 ; median age 34; range 16-52 years), one was positive for CHRPE and 12 were free of retinal lesions. The sensitivity of the presence of a CHRPE lesion in association with colonic polyps in FAP was 76%, specificity 92%, positive predictive value 93%, and negative predictive value 75%. This study found a high sensitivity and specificity for a CHRPE lesion to be associated with colonic polyps of FAP and hence a useful screening method in a burdened health-care system. The method is minimally invasive and simple and would be of particular value in screening children at risk for FAP.

Hypoglycaemia is a common cause of morbidity in dogs with congenital portosystemic shunts but the aetiology is unknown. The hypothesis of this study was that dogs with congenital portosystemic shunts would have significantly higher insulin concentrations than dogs without congenital portosystemic shunts. The main objective of the study was to compare peripheral glucose and insulin concentrations between dogs with congenital portosystemic shunts and dogs without congenital portosystemic shunts. Peripheral serum insulin and plasma glucose concentrations were measured in dogs with congenital portosystemic shunts and without congenital portosystemic shunts and compared both between groups as well as to reference intervals derived from healthy dogs. Congenital portosystemic shunts were diagnosed in 41 dogs. Forty-eight dogs hospitalised with other conditions acted as controls. Serum insulin concentrations were mildly elevated (Ä40 μU/mL) in seven dogs and were markedly elevated in two dogs with congenital portosystemic shunts, yet mild hypoglycaemia (3·3 mmol/L) was detected in only one of these dogs. Four dogs with congenital portosystemic shunts showed fasting hypoglycaemia, yet insulin concentrations were within or below the reference interval in three. There was no difference between the median insulin concentration of dogs with congenital portosystemic shunts and without congenital portosystemic shunts. Hyperinsulinaemia is infrequently observed in dogs with congenital portosystemic shunts. The aetiology of hypoglycaemia in dogs with congenital portosystemic shunts merits further investigation. © 2012 British Small Animal Veterinary Association.

Congenital neutropenia is a heterogeneous bone marrow failure syndrome characterized by a maturation arrest of myelopoesis at the promyelocyte/myelocyte stage. Cyclic neutropenia (CyN) and severe congenital neutropenia (SCN) are two main forms of congenital neutropenia. Genetic analysis has shown that heterozygous mutations in the ELANE gene encoding the neutrophil elastase are the major cause of these disorders. We investigated the prevalence of ELANE mutations in a group of 16 patients from 14 families with congenital neutropenia. Five patients had typical manifestations of CyN, and 11 patients had SCN. Seven different heterozygous ELANE mutations were found, including four novel mutations. Copyright © 2011 Wiley-Liss, Inc.

Congenital heart defects are the most common of all congenital malformations, with a review of the literature reporting the incidence at 6 to 8 per 1000 live births. The Centers for Disease Control reports cyanotic heart defects occurred in 56.9 per 100,000 live births in the United States in 2005, with higher rates noted when maternal age exceeded 40 years. The incidence of congenital heart disease in premature infants is 12.5 per 1000 live births, excluding isolated patent ductus arteriosus and atrial septal defect. Despite advances in detection and treatment, congenital heart disease accounts for 3% of all infant deaths and 46% of death from congenital malformations. This article discusses the embryology, pathogenesis, clinical presentation, incidence, classifications, and management of congenital heart diseases.

The Tasmanian tiger or thylacine (Thylacinus cynocephalus) was an iconic Australian marsupial predator that was hunted to extinction in the early 1900s. Despite sharing striking similarities with canids, they failed to evolve many of the specialized anatomical features that characterize carnivorous placental mammals. These evolutionary limitations are thought to arise from functional constraints associated with the marsupial mode of reproduction, in which otherwise highly altricial young use their well-developed forelimbs to climb to the pouch and mouth to suckle. Here we present the first three-dimensional digital developmental series of the thylacine throughout its pouch life using X-ray computed tomography on all known ethanol-preserved specimens. Based on detailed skeletal measurements, we refine the species growth curve to improve age estimates for the individuals. Comparison of allometric growth trends in the appendicular skeleton (fore- and hindlimbs) with that of other placental and marsupial mammals revealed that despite their unique adult morphologies, thylacines retained a generalized early marsupial ontogeny. Our approach also revealed mislabelled specimens that possessed large epipubic bones (vestigial in thylacine) and differing vertebral numbers. All of our generated CT models are publicly available, preserving their developmental morphology and providing a novel digital resource for future studies of this unique marsupial. PMID:29515893

To evaluate the diagnostic value of anti-microbial peptide (cathelicidin), LL-37, in congenital pneumonia and its relation to 25 hydroxycholecalciferol [(25 OH)D] status. The study included 30 neonates with congenital pneumonia and culture proven sepsis admitted to neonatal intensive care unit of Ain Shams University and 30 healthy neonates as control group. All neonates were subjected to history taking, clinical examination and measurement of serum 25(OH)D and cathelicidin. Neonates with congenital pneumonia had significantly higher serum cathelicidin and lower serum 25(OH)D compared to controls. Serum cathelicidin was negatively correlated with Apgar score at 1 and 5 min and positively correlated with length of stay among patient group. Cut-off value of cathelicidin to diagnose congenital pneumonia was 17 pg/mmol with 93% sensitivity and 86% specificity. Neonates with congenital pneumonia had significantly high cathelicidin and low 25(OH)D suggesting a possible role of fetal 25(OH)D deficiency as predisposing factor for congenital pneumonia.

In acromegaly the long-term exposure to high growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels may result in specific complications in different human organs, including the thyroid gland and the colon. We will review here the evidence available regarding the characteristic thyroid and colon complications in acromegaly. This review summarizes the published data observing noncancerous structural abnormalities (thyroid nodules, colonic polyps) and thyroid and colon cancer in patients diagnosed with acromegaly. Thyroid micro-carcinomas are probably over-diagnosed among acromegalic patients. In regard to colon cancer, there is no sufficient data to suggest that colon cancer risk is higher in acromegaly compared to the general population.

Assessment of the long-term stability of retort pouch foods to support extended duration spaceflight.

2012-01-01

To determine the suitability of retort processed foods to support long-duration spaceflight, a series of 36-mo accelerated shelf life studies were performed on 13 representative retort pouch products. Combined sensory evaluations, physical properties assessments, and nutritional analyses were employed to determine shelf life endpoints for these foods, which were either observed during the analysis or extrapolated via mathematical projection. Data obtained through analysis of these 13 products were later used to estimate the shelf life values of all retort-processed spaceflight foods. In general, the major determinants of shelf life appear to be the development of off-flavor and off-color in products over time. These changes were assumed to be the result of Maillard and oxidation reactions, which can be initiated or accelerated as a result of the retort process and product formulation. Meat products and other vegetable entrées are projected to maintain their quality the longest, between 2 and 8 y, without refrigeration. Fruit and dessert products (1.5 to 5 y), dairy products (2.5 to 3.25 y), and starches, vegetable, and soup products (1 to 4 y) follow. Aside from considerable losses in B and C vitamin content, nutritional value of most products was maintained throughout shelf life. Fortification of storage-labile vitamins was proposed as a countermeasure to ensure long-term nutritive value of these products. The use of nonthermal sterilization technologies was also recommended, as a means to improve initial quality of these products and extend their shelf life for use in long-duration missions. Data obtained also emphasize the importance of low temperature storage in maintaining product quality. Retort sterilized pouch products are garnering increased commercial acceptance, largely due to their improved convenience and quality over metal-canned products. Assessment of the long-term stability of these products with ambient storage can identify potential areas for

Background Neonatal infections cause a significant proportion of deaths in the first week of life, yet little is known about risk factors and pathways of transmission for early-onset neonatal sepsis globally. We aimed to estimate the risk of neonatal infection (excluding sexually transmitted diseases [STDs] or congenital infections) in the first seven days of life among newborns of mothers with bacterial infection or colonization during the intrapartum period. Methods and Findings We searched PubMed, Embase, Scopus, Web of Science, Cochrane Library, and the World Health Organization Regional Databases for studies of maternal infection, vertical transmission, and neonatal infection published from January 1, 1960 to March 30, 2013. Studies were included that reported effect measures on the risk of neonatal infection among newborns exposed to maternal infection. Random effects meta-analyses were used to pool data and calculate the odds ratio estimates of risk of infection. Eighty-three studies met the inclusion criteria. Seven studies (8.4%) were from high neonatal mortality settings. Considerable heterogeneity existed between studies given the various definitions of laboratory-confirmed and clinical signs of infection, as well as for colonization and risk factors. The odds ratio for neonatal lab-confirmed infection among newborns of mothers with lab-confirmed infection was 6.6 (95% CI 3.9–11.2). Newborns of mothers with colonization had a 9.4 (95% CI 3.1–28.5) times higher odds of lab-confirmed infection than newborns of non-colonized mothers. Newborns of mothers with risk factors for infection (defined as prelabour rupture of membranes [PROM], preterm <37 weeks PROM, and prolonged ROM) had a 2.3 (95% CI 1.0–5.4) times higher odds of infection than newborns of mothers without risk factors. Conclusions Neonatal infection in the first week of life is associated with maternal infection and colonization. High-quality studies, particularly from settings with high

OBJECTIVE--To study the effect of periconceptional multivitamin supplementation on neural tube defects and other congenital abnormality entities. DESIGN--Randomised controlled trial of supplementation with multivitamins and trace elements. SETTING--Hungarian family planning programme. SUBJECTS--4156 pregnancies with known outcome and 3713 infants evaluated in the eighth month of life. INTERVENTIONS--A single tablet of a multivitamin including 0.8 mg of folic acid or trace elements supplement daily for at least one month before conception and at least two months after conception. MAIN OUTCOME MEASURES--Number of major and mild congenital abnormalities. RESULTS--The rate of all major congenital abnormalities was significantly lower in the group given vitamins than in the group given trace elements and this difference cannot be explained totally by the significant reduction of neural tube defects. The rate of major congenital abnormalities other than neural tube defects and genetic syndromes was 9.0/1000 in pregnancies with known outcome in the vitamin group and 16.6/1000 in the trace element group; relative risk 1.85 (95% confidence interval 1.02 to 3.38); difference, 7.6/1000. The rate of all major congenital abnormalities other than neural tube defects and genetic syndromes diagnosed up to the eighth month of life was 14.7/1000 informative pregnancies in the vitamin group and 28.3/1000 in the trace element group; relative risk 1.95 (1.23 to 3.09); difference, 13.6/1000. The rate of some congenital abnormalities was lower in the vitamin group than in the trace element group but the differences for each group of abnormalities were not significant. CONCLUSIONS--Periconceptional multivitamin supplementation can reduce not only the rate of neural tube defects but also the rate of other major non-genetic syndromatic congenital abnormalities. Further studies are needed to differentiate the chance effect and vitamin dependent effect. PMID:8324432

Health-related quality of life (HRQL) and disability were compared in ulcerative colitis (UC) patients who underwent restorative proctocolectomy versus patients who received treatment with anti-tumor necrosis factor (anti-TNF) agents. UC patients who underwent restorative proctocolectomy or started anti-TNF treatment between January 2010 and January 2015 were included at two tertiary referral centers. A matched cohort was created using propensity score matching for the covariates disease duration, Montreal classification, age, and sex. HRQL and disability were assessed using the Colorectal Functional Outcome (COREFO), Inflammatory Bowel Disease Disability Index (IBD-DI), EuroQol-5D-3L, and Short Form 36 (SF-36) questionnaires. In total, 297 patients were included, of whom 205 (69%) patients responded. Fifty-nine pouch patients were matched to 59 anti-TNF-treated patients. Pouch patients reported better general health scores (P=0.042) compared with the anti-TNF group (SF-36). No differences were found for the EuroQol-5D-3L and IBD-DI between the two groups. Pouch patients had significantly higher COREFO scores compared with anti-TNF-treated patients for 'stool frequency' (P<0.001), 'antidiarrheal medication use' (P<0.001), and 'stool-related aspects' (P=0.004), of which the latter was because of a higher perianal skin irritation frequency (P<0.001). UC patients who underwent restorative proctocolectomy reported a higher bowel movement frequency and more perianal skin irritation compared with anti-TNF-treated patients, but this did not affect overall disease-specific disability outcomes. Patients in the surgery group reported better outcomes for generic health compared with those in the anti-TNF group.

Recent progress in scientific research has facilitated accurate genetic and neuropathological diagnosis of congenital myopathies. However, given their relatively low incidence, congenital myopathies remain unfamiliar to the majority of care providers, and the levels of patient care are extremely variable. This consensus statement aims to provide care guidelines for congenital myopathies. The International Standard of Care Committee for Congenital Myopathies worked through frequent e-mail correspondences, periodic conference calls, 2 rounds of online surveys, and a 3-day workshop to achieve a consensus for diagnostic and clinical care recommendations. The committee includes 59 members from 10 medical disciplines. They are organized into 5 working groups: genetics/diagnosis, neurology, pulmonology, gastroenterology/nutrition/speech/oral care, and orthopedics/rehabilitation. In each care area the authors summarize the committee’s recommendations for symptom assessments and therapeutic interventions. It is the committee’s goal that through these recommendations, patients with congenital myopathies will receive optimal care and improve their disease outcome. PMID:22431881

Introduction Congenital heart disease is an abnormality in the structure or cardiocirculatory function, occurring from birth, even if diagnosed later. It can result in intrauterine death in childhood or in adulthood. Accounted for 6% of infant deaths in Brazil in 2007. Objective To estimate underreporting in the prevalence of congenital heart disease in Brazil and its subtypes. Methods The calculations of prevalence were performed by applying coefficients, giving them function rates for calculations of health problems. The study makes an approach between the literature and the governmental registries. It was adopted an estimate of 9: 1000 births and prevalence rates for subtypes applied to births of 2010. Estimates of births with congenital heart disease were compared with the reports to the Ministry of Health and were studied by descriptive methods with the use of rates and coefficients represented in tables. Results The incidence in Brazil is 25,757 new cases/year, distributed in: North 2,758; Northeast 7,570; Southeast 10,112; South 3,329; and Midwest 1,987. In 2010, were reported to System of Live Birth Information of Ministry of Health 1,377 cases of babies with congenital heart disease, representing 5.3% of the estimated for Brazil. In the same period, the most common subtypes were: ventricular septal defect (7,498); atrial septal defect (4,693); persistent ductus arteriosus (2,490); pulmonary stenosis (1,431); tetralogy of Fallot (973); coarctation of the aorta (973); transposition of the great arteries (887); and aortic stenosis 630. The prevalence of congenital heart disease, for the year of 2009, was 675,495 children and adolescents and 552,092 adults. Conclusion In Brazil, there is underreporting in the prevalence of congenital heart disease, signaling the need for adjustments in the methodology of registration. PMID:26107454

Liver disease is a major cause of morbidity and mortality. One of the most significant complications in patients with liver disease is the development of neurological disturbances, termed hepatic encephalopathy. The pathogenesis of hepatic encephalopathy is incompletely understood, which has resulted in the development of a wide range of experimental models. Congenital portosystemic shunt is one of the most common congenital disorders diagnosed in client owned dogs. Our recent studies have demonstrated that the pathophysiology of canine hepatic encephalopathy is very similar to human hepatic encephalopathy, which provides strong support for the use of dogs with a congenital portosystemic shunt as a naturally occurring model of human hepatic encephalopathy. Specifically, we have demonstrated an important role for ammonia and inflammation in the development of hepatic encephalopathy in dogs with a congenital portosystemic shunt. Despite the apparent importance of inflammation in driving hepatic encephalopathy in dogs, it is unclear whether inflammation resolves following the successful treatment of liver disease. We hypothesized that haematological and biochemical evidence of inflammation, as gauged by neutrophil, lymphocyte and monocyte concentrations together with C-reactive protein concentrations, would decrease following successful treatment of congenital portosystemic shunts in dogs. One hundred and forty dogs with a congenital portosystemic shunt were enrolled into the study. We found that the proportion of dogs with a monocyte concentration above the reference range was significantly greater in dogs with hepatic encephalopathy at time of initial diagnosis. Importantly, neutrophil and monocyte concentrations significantly decreased following surgical congenital portosystemic shunt attenuation. We also found a significant decrease in C-reactive protein concentrations following surgical attenuation of congenital portosystemic shunts. Our study demonstrates that

Objective Central systolic blood pressure (SBP) is a measure of arterial stiffness and strongly associated with atherosclerosis and end-organ damage. It is a stronger predictor of cardiovascular events and all-cause mortality than peripheral SBP. In particular, for children with congenital heart disease, a higher central SBP might impose a greater threat of cardiac damage. The aim of the study was to analyse and compare central SBP in children with congenital heart disease and in healthy counterparts. Patients and methods Central SBP was measured using an oscillometric method in 417 children (38.9% girls, 13.0 ± 3.2 years) with various congenital heart diseases between July 2014 and February 2017. The test results were compared with a recent healthy reference cohort of 1466 children (49.5% girls, 12.9 ± 2.5 years). Results After correction for several covariates in a general linear model, central SBP of children with congenital heart disease was significantly increased (congenital heart disease: 102.1 ± 10.2 vs. healthy reference cohort: 100.4 ± 8.6, p < .001). The analysis of congenital heart disease subgroups revealed higher central SBP in children with left heart obstructions (mean difference: 3.6 mmHg, p < .001), transpositions of the great arteries after arterial switch (mean difference: 2.2 mmHg, p = .017) and univentricular hearts after total cavopulmonary connection (mean difference: 2.1 mmHg, p = .015) compared with the reference. Conclusion Children with congenital heart disease have significantly higher central SBP compared with healthy peers, predisposing them to premature heart failure. Screening and long-term observations of central SBP in children with congenital heart disease seems warranted in order to evaluate the need for treatment.

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.

The Aristotle Basic Complexity score and the Risk Adjustment in Congenital Heart Surgery system were developed by consensus to compare outcomes of congenital cardiac surgery. We compared the predictive value of the 2 systems. Of all index congenital cardiac operations at our institution from 1982 to 2004 (n = 13,675), we were able to assign an Aristotle Basic Complexity score, a Risk Adjustment in Congenital Heart Surgery score, and both scores to 13,138 (96%), 11,533 (84%), and 11,438 (84%) operations, respectively. Models of in-hospital mortality and length of stay were generated for Aristotle Basic Complexity and Risk Adjustment in Congenital Heart Surgery using an identical data set in which both Aristotle Basic Complexity and Risk Adjustment in Congenital Heart Surgery scores were assigned. The likelihood ratio test for nested models and paired concordance statistics were used. After adjustment for year of operation, the odds ratios for Aristotle Basic Complexity score 3 versus 6, 9 versus 6, 12 versus 6, and 15 versus 6 were 0.29, 2.22, 7.62, and 26.54 (P < .0001). Similarly, odds ratios for Risk Adjustment in Congenital Heart Surgery categories 1 versus 2, 3 versus 2, 4 versus 2, and 5/6 versus 2 were 0.23, 1.98, 5.80, and 20.71 (P < .0001). Risk Adjustment in Congenital Heart Surgery added significant predictive value over Aristotle Basic Complexity (likelihood ratio chi2 = 162, P < .0001), whereas Aristotle Basic Complexity contributed much less predictive value over Risk Adjustment in Congenital Heart Surgery (likelihood ratio chi2 = 13.4, P = .009). Neither system fully adjusted for the child's age. The Risk Adjustment in Congenital Heart Surgery scores were more concordant with length of stay compared with Aristotle Basic Complexity scores (P < .0001). The predictive value of Risk Adjustment in Congenital Heart Surgery is higher than that of Aristotle Basic Complexity.

To compare the serum level of hyaluronic acid in dogs with congenital portosystemic shunt with that in healthy dogs and to investigate the perioperative change in serum hyaluronic acid following shunt attenuation. Blood samples were obtained from 29 congenital portosystemic shunt dogs before the operation, and 2 and 4 weeks after the operation from 17 and 7 dogs, respectively. The serum hyaluronic acid level of these dogs was measured and compared with that of 10 healthy beagles. The median preoperative hyaluronic acid level in dogs with congenital portosystemic shunt was significantly elevated compared with that in healthy dogs. Furthermore, the median postoperative hyaluronic acid level significantly decreased compared with the median preoperative levels in congenital portosystemic shunt dogs. In the case of dogs with congenital portosystemic shunt, the reduction of intrahepatic portal blood flow might lower the clearance rate of hyaluronic acid in hepatic sinusoidal endothelial cells, so hyaluronic acid clearance could be improved by attenuation of a shunt vessel. Hence, serum hyaluronic acid levels might be useful to evaluate liver function and also have the potential to evaluate successful attenuation of a shunt vessel in dogs with congenital portosystemic shunt. Further investigations are required to clarify whether serum hyaluronic acid offers significant benefits over existing markers such as serum bile acid or ammonia concentrations.

Previous studies have shown that early life trauma induced by maternal separation or colonic irritation leads to hypersensitivity to colorectal distension in adulthood. We tested the hypothesis that repetitive colorectal distension in neonates leads to abnormalities in colonic permeability and smooth muscle function in the adult rat. In neonatal rats, repetitive colorectal distension was performed on days 8, 10, and 12. As adults, stool consistency was graded from 0 (formed stool) to 3 (liquid stool). Colonic tissue was isolated for histology and myeloperoxidase levels. The colonic mucosa was placed in modified Ussing chambers for measurements of permeability and short-circuit current responses to forskolin, electrical field stimulation, and carbachol. Segments of colonic musculature were placed in organ baths and contractile response to potassium chloride, electrical field stimulation, and carbachol were determined. In adult rats that experienced neonatal colonic irritation, no significant changes in colonic histology or myeloperoxidase activity were observed; however, stool consistency scores were increased. Mucosal permeability, measured as an increase in basal conductance, was significantly increased but no changes in short-circuit current responses were observed. In adulthood, rats that underwent colorectal distension as neonates exhibited an elevated smooth muscle contractile response to potassium chloride, but no changes in response to electrical field stimulation or carbachol. In summary, neonatal colonic irritation, shown previously to produce colonic hypersensitivity, leads to significant alterations in colonic mucosal and smooth muscle function characterized by loose stools, increased mucosal permeability, and increased smooth muscle contractility in the absence of colon inflammation in adulthood.

Unilateral lung agenesis is an uncommon congenital abnormality, with a lack of reported accurate incidence estimates. Prognosis is also uncertain, with older literature reporting poor outcomes. The North of England register of congenital anomalies (Northern Congenital Abnormality Survey) records cases of congenital anomalies to mothers' resident in the region. We used the register to identify all patients with congenital lung agenesis born between 2004 and 2013 to calculate an accurate incidence estimate and report clinical outcomes with contemporary management. Four patients with congenital lung agenesis were born during the study period, giving an estimated incidence in the North of England of 1.22 per 100,000 live births (95% confidence interval, 0.33-3.11). Two patients had associated congenital heart disease requiring corrective surgery, and one had musculoskeletal anomalies. All four patients are alive and well without a regular oxygen requirement. Contrary to previous reports, the medium term outcomes in our patients have been good, even when lung agenesis is associated with other congenital anomalies. Long-term prognosis with modern management remains unknown, and the potential for the development of pulmonary hypertension remains a concern.

A case of moving ileal Taenia saginata parasites is presented with demonstrative images. We came across the parasites surprisingly while performing robot-assisted laparoscopic radical cystoprostatectomy with intracorporeal Studer pouch urinary diversion. We recommend stool sample evaluation in the preoperative period for possible presence of intestinal parasitic diseases, particularly in patients with bladder cancer who are admitted from areas with an increased incidence of intestinal parasitic diseases, before opening the bowel segments during surgery to perform radical cystectomy and urinary diversion.

Congenital hypothyroidism is a rare and underdiagnosed congenital endocrine disorder in dogs and cats and the true incidence is unknown. The disorder may cause a range of clinical signs depending on the primary defect, which affect production of thyroid hormones; some cases present when adult. Hallmark clinical signs of congenital hypothyroidism are mental impairment and skeletal developmental abnormalities, resulting in disproportionate dwarfism; goitre may or may not be present. Documented causes of congenital hypothyroidism in dogs include deficiency of, or unresponsiveness to, thyrotropin-releasing hormone (TRH) or thyroid-stimulating hormone (TSH), thyroid dysgenesis, dyshormonogenesis and iodine deficiency. In cats, TSH unresponsiveness, thyroid dysgenesis, dyshormonogenesis and iodine deficiency have been confirmed. Adequate replacement therapy results in a successful outcome in the majority of cases, especially when started early in life, as permanent developmental abnormalities can be prevented. This review describes reported cases in dogs and cats, diagnostic investigation, and recommendations for treatment.

The consensus is that a minimum of 12 lymph nodes should be analyzed at colectomy for colon cancer. However, right colon cancer and left colon cancer have different characteristics, and this threshold value for total number of lymph nodes retrieved may not be universally applicable. The data of 63,243 patients with colon cancer treated between 2004 and 2012 were retrieved from the National Cancer Institute's Surveillance, Epidemiology, and End Results database. Multivariate Cox regression analysis was used to determine the predictive value of total number of lymph nodes for survival after adjusting for lymph nodes ratio. The predictive value in left-sided colon cancer and right-sided colon cancer was compared. The optimal total number of lymph nodes cutoff value for prediction of overall survival was identified using the online tool Cutoff Finder. Survival of patients with high total number of lymph nodes (≥12) and low total number of lymph nodes (< 12) was compared by Kaplan-Meier analysis. After stratifying by lymph nodes ratio status, total number of lymph nodes≥12 remained an independent predictor of survival in the whole cohort and in right-sided colon cancer, but not in left-sided colon cancer. The optimal cutoff value for total number of lymph nodes was determined to be 11. Low total number of lymph nodes (< 11) was associated with significantly poorer survival after adjusting for lymph nodes ratio in all subgroups except in the subgroup with high lymph nodes ratio (0.5-1.0). Previous reports of the prognostic significance of total number of lymph nodes on node-positive colon cancer were confounded by lymph nodes ratio. The 12-node standard for total number of lymph nodes may not be equally applicable in right-sided colon cancer and left-sided colon cancer.

The genetics of congenital heart disease… understanding and improving long-term outcomes in congenital heart disease: a review for the general cardiologist and primary care physician.

PubMed

Simmons, M Abigail; Brueckner, Martina

2017-10-01

This review has two purposes: to provide an updated review of the genetic causes of congenital heart disease (CHD) and the clinical implications of these genetic mutations, and to provide a clinical algorithm for clinicians considering a genetics evaluation of a CHD patient. A large portion of congenital heart disease is thought to have a significant genetic contribution, and at this time a genetic cause can be identified in approximately 35% of patients. Through the advances made possible by next generation sequencing, many of the comorbidities that are frequently seen in patients with genetic congenital heart disease patients can be attributed to the genetic mutation that caused the congenital heart disease. These comorbidities are both cardiac and noncardiac and include: neurodevelopmental disability, pulmonary disease, heart failure, renal dysfunction, arrhythmia and an increased risk of malignancy. Identification of the genetic cause of congenital heart disease helps reduce patient morbidity and mortality by improving preventive and early intervention therapies to address these comorbidities. Through an understanding of the clinical implications of the genetic underpinning of congenital heart disease, clinicians can provide care tailored to an individual patient and continue to improve the outcomes of congenital heart disease patients.

Congenital absence of dermatoglyphs.

Congenital absence or unusual patterns of human dermatoglyphs (fingerprints) occur in several syndromes that are rare and poorly understood. The abnormalities of dermatoglyphs fall into four categories: complete absence, ridge hypoplasia, ridge dissociation, and ridges-off-the-end. Complete congenital absence of ridges is an exceedingly rare syndrome that consists of neonatal blisters and milia, adult traumatic blistering and fissuring, absence of sweating, contracture of digits, and absence of dermatoglyphs on the hands and feet. The syndrome is inherited in an autosomal dominant pattern, and only two kindreds have been described in the literature. We describe a newly identified patient and kindred with findings similar to the previously reported cases and review the clinical and histopathologic findings of this syndrome.

Restorative coloproctectomy (RCP) with ileal pouch-anal anastomosis (IPAA), is one of the surgical responses to the crucial question of prophylactic treatment in familial adenomatous polyposis (FAP). No consensus has been reached, until now, to choose between IPAA and ileo-rectal anastomosis (IRA), the rectal sparing prophylactic colectomy. This paper aims to review the latest issues related to IPAA and highlights its specificities compared to IRA. PubMed database was searched using the following search items: familial adenomatous polyposis, surgery, ileal pouch-anal anastomosis, ileo-rectal anastomosis. Papers published between 1978 and 2010 were selected. Absence of mortality, acceptable morbidity and good functional results combined to high quality of life have promoted the IPAA technique. New technical issues such as the double stapled technique, mesenteric lengthening, omission of temporary protective stoma can be addressed almost systematically for these patients. A laparoscopic approach, lessening the body image impact, has proven to be as effective and safe as the open approach to perform IPAA. Further advantages of laparoscopic IPAA rely on the lower adhesion formation resulting in less small bowel occlusion. Sexuality, fertility and childbirth are important functional issues often cited as threatened by the pelvic manoeuvres of the IPAA technique which can be prevented by close rectal wall dissection and a laparoscopic approach. IPAA offers the best available prophylaxis in FAP patients. Technical enhancements in IPAA will most probably decrease the functional risks. Thus IPAA remains the alternative to IRA for the prophylactic treatment of FAP.Nevertheless, based on the latest evidence, the choice between both procedures is still matter of debate.

We report on a series of patients with congenital anosmia to analyze its clinical characteristics and present illustrative cases. retrospective chart review. tertiary care centre. thirty-five patients with congenital anosmia were reviewed. A thorough medical history taking, physical examination, and nasal endoscopy were performed in all patients. T&T olfactory testing (n = 33), olfactory event-related potentials (OERPs) (n = 33), and sinonasal computed tomography (CT) (n = 35) were carried out. Magnetic resonance images (MRIs) of the olfactory pathway (n = 34) were available. Serum sex hormones were tested (n = 33). physical examination, olfactory testing, MRI of the olfactory pathway, and serum sex hormones. twenty cases were isolated congenital anosmia (ICA). Fifteen cases were congenital anosmia with other anomalies, including 12 cases with Kallmann syndrome (KS), two with CHARGE syndrome, and one with hypoplasia of the nasal cavity and nasal sinus. T&T olfactory testing indicated anosmia (n = 33). No OERP was obtained (n = 33). CT scans indicated three abnormal patients, including two with unilateral choanal atresia and one with hypoplasia of the nasal cavity and sinus. MRI demonstrated aplasia or hypoplasia of the olfactory bulbs, tracts, and olfactory sulci (n = 34). Serum sex hormones were low in 12 patients with KS. early diagnosis of congenital anosmia on the basis of olfactory symptoms is difficult. MRI of the olfactory pathway plays an important role in anatomic location. ICA is the most common congenital anosmia. KS is the primary presentation of congenital anosmia with other anomalies.

The “Silent” Global Burden of Congenital Cytomegalovirus

Human cytomegalovirus (CMV) is a leading cause of congenital infections worldwide. In the developed world, following the virtual elimination of circulating rubella, it is the commonest nongenetic cause of childhood hearing loss and an important cause of neurodevelopmental delay. The seroprevalence of CMV in adults and the incidence of congenital CMV infection are highest in developing countries (1 to 5% of births) and are most likely driven by nonprimary maternal infections. However, reliable estimates of prevalence and outcome from developing countries are not available. This is largely due to the dogma that maternal preexisting seroimmunity virtually eliminates the risk for sequelae. However, recent data demonstrating similar rates of sequelae, especially hearing loss, following primary and nonprimary maternal infection have underscored the importance of congenital CMV infection in resource-poor settings. Although a significant proportion of congenital CMV infections are attributable to maternal primary infection in well-resourced settings, the absence of specific interventions for seronegative mothers and uncertainty about fetal prognosis have discouraged routine maternal antibody screening. Despite these challenges, encouraging results from prototype vaccines have been reported, and the first randomized phase III trials of prenatal interventions and prolonged postnatal antiviral therapy are under way. Successful implementation of strategies to prevent or reduce the burden of congenital CMV infection will require heightened global awareness among clinicians and the general population. In this review, we highlight the global epidemiology of congenital CMV and the implications of growing knowledge in areas of prevention, diagnosis, prognosis, and management for both low (50 to 70%)- and high (>70%)-seroprevalence settings.

As the adult congenital heart disease population increases, poor transition from pediatric to adult care can lead to suboptimal quality of care and an increase in individual and institutional costs. In 2008, the American College of Cardiology and American Heart Association updated the adult congenital heart disease practice guidelines and in 2011, the American Heart Association recommended transition guidelines to standardize and encourage appropriate timing of transition to adult cardiac services. The objective of this study was to evaluate if patient age or complexity of congenital heart disease influences pediatric cardiologists' decision to transfer care to adult providers and to evaluate the compliance of different types of cardiology providers with current adult congenital heart disease treatment guidelines. A single-center retrospective review of 991 adult congenital heart disease patients identified by ICD-9 code from 2010 to 2012. Academic and community outpatient cardiology clinics. Nine hundred ninety-one patients who are 18 years and older with congenital heart disease. None. The compliance with health maintenance and transfer of care recommendations in the outpatient setting. For patients seen by pediatric cardiologists, only 20% had transfer of care discussions documented, most often in younger simple patients. Significant differences in compliance with preventative health guidelines were found between cardiology provider types. Even though a significant number of adults with congenital heart disease are lost to appropriate follow-up in their third and fourth decades of life, pediatric cardiologists discussed transfer of care with moderate and complex congenital heart disease patients less frequently. Appropriate transfer of adults with congenital heart disease to an adult congenital cardiologist provides an opportunity to reinforce the importance of regular follow-up in adulthood and may improve outcomes as adult congenital cardiologists followed the

In spite of availability of cost-effective preventive measures and treatment, a resurgence of congenital syphilis has currently been noted. During the past 4 years, we came across five low birth weight neonates with unusual symptoms, which subsequently proved to be manifestations of early congenital syphilis. All the mothers had apparently uneventful antenatal period. No investigation was done during pregnancy. They were unaware about their disease and were found to be positive for syphilis by Venereal Disease Research Laboratory Test and fluorescent treponemal antibody (absorbed) IgM test only after childbirth. Screening for other congenital infections was negative. All the neonates were positive for Venereal Disease Research Laboratory Test. They were treated with intravenous crystalline penicillin G for 10 days. Recovery was uneventful. We reemphasize the importance of raising public awareness, routine antenatal screening and treatment for all pregnant mothers to avoid such a potentially treatable condition.

The Hungarian Congenital Malformation Monitor has been operating since 1973 in order to detect the temporal and regional clusters of 12 indicator congenital malformations as early as possible. This Monitor takes part in the International Clearinghouse for Birth Defects Monitoring System. Three continuously increasing trends were detected in 1973--1976. They may be connected with the more complete notifications, although the increase of limb reduction deformities are only partly explained by this factor. Transitional (quarterly) significant clusters were observed in the case of anencephaly (1974, IV), spina bifida (1974, II; and 1975, III; 1976, III), cleft lip +/- cleft palate (1974, III). The possibility of three technical biases (changes in diagnosis, notification and evaluation of the given congenital malformation) has to be excluded before accepting the fact of a real epidemic. Subsequently, a case-control epidemiological study by personal interviews and with matched controls has to be performed.

Changing Landscape of Congenital Heart Disease.

Congenital heart disease is the most frequently occurring congenital disorder affecting ≈0.8% of live births. Thanks to great efforts and technical improvements, including the development of cardiopulmonary bypass in the 1950s, large-scale repair in these patients became possible, with subsequent dramatic reduction in morbidity and mortality. The ongoing search for progress and the growing understanding of the cardiovascular system and its pathophysiology refined all aspects of care for these patients. As a consequence, survival further increased over the past decades, and a new group of patients, those who survived congenital heart disease into adulthood, emerged. However, a large range of complications raised at the horizon as arrhythmias, endocarditis, pulmonary hypertension, and heart failure, and the need for additional treatment became clear. Technical solutions were sought in perfection and creation of new surgical techniques by developing catheter-based interventions, with elimination of open heart surgery and new electronic devices enabling, for example, multisite pacing and implantation of internal cardiac defibrillators to prevent sudden death. Over time, many pharmaceutical studies were conducted, changing clinical treatment slowly toward evidence-based care, although results were often limited by low numbers and clinical heterogeneity. More attention has been given to secondary issues like sports participation, pregnancy, work, and social-related difficulties. The relevance of these issues was already recognized in the 1970s when the need for specialized centers with multidisciplinary teams was proclaimed. Finally, research has become incorporated in care. Results of intervention studies and registries increased the knowledge on epidemiology of adults with congenital heart disease and their complications during life, and at the end, several guidelines became easily accessible, guiding physicians to deliver care appropriately.

Congenital heart defects affect nearly 1% of all newborns and are a significant cause of infant death. Clinical studies have identified a number of congenital heart syndromes associated with mutations in genes that are involved in the complex process of cardiogenesis. The African clawed frog, Xenopus, has been instrumental in studies of vertebrate heart development and provides a valuable tool to investigate the molecular mechanisms underlying human congenital heart diseases. In this review, we discuss the methodologies that make Xenopus an ideal model system to investigate heart development and disease. We also outline congenital heart conditions linked to cardiac genes that have been well-studied in Xenopus and describe some emerging technologies that will further aid in the study of these complex syndromes.

Congenital heart disease is the most common congenital defect. During childhood, survival is generally good but, in adulthood, late complications are not uncommon. Abnormal autonomic control in children with congenital heart disease may contribute considerably to the pathophysiology of these long term sequelae. This narrative review of 34 studies aims to summarize current knowledge on function of the autonomic nervous system in children with a congenital heart defect. Large scale studies that measure both branches of the nervous system for prolonged periods of time in well-defined patient cohorts in various phases of childhood and adolescence are currently lacking. Pending such studies, there is not yet a good grasp on the extent and direction of sympathetic and parasympathetic autonomic function in pediatric congenital heart disease. Longitudinal studies in homogenous patient groups linking autonomic nervous system function and clinical outcome are warranted. PMID:29367565

Golden Syrian hamsters are evaluated as an animal model for phototherapy of early squamous cell carcinomas of the mucosa of the upper aerodigestive tract, the esophagus and the tracheobronchial tree. Carcinomas of this type are induced on the hamster cheek pouch mucosa by the application of the carcinogen 7,12 DMBA. For phototherapeutic experiments on the animals we utilized meso- (tetrahydoxyphenyl)chlorin (mTHPC). The same drug is currently in phase I, II clinical trials for ENT patients with superficial squamous cell carcinomas. By means of light induced fluorescence (LIF) we measured in vivo the kinetics of the uptake and removal of mTHPC in the normal and tumoral cheek mucosa and in the skin. The photodynamic therapy (PDT) reaction of the tissue after excitation of the photosensitizer by laser light at 652 nm was studied. Both pharmacokinetics and PDT efficacy are compared between animal model and clinical results with special emphasis on selectivity between normal and tumoral mucosa. These first experiments show that this tumor model in the hamster cheek pouch seems to be suitable for tests of a number of PDT variables of new photosensitizers preceding their clinical application as well as for optimization of the multiple parameters of clinical phototherapy.

AIM: To provide further insight into the characterization of mucosa-associated Escherichia coli (E. coli) isolated from the colonic mucosa of cancer patients. METHODS: Phylogroups and the presence of cyclomodulin-encoding genes of mucosa-associated E. coli from colon cancer and diverticulosis specimens were determined by PCR. Adhesion and invasion experiments were performed with I-407 intestinal epithelial cells using gentamicin protection assay. Carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) expression in T84 intestinal epithelial cells was measured by enzyme-linked immunosorbent assay and by Western Blot. Gut colonization, inflammation and pro-carcinogenic potential were assessed in a chronic infection model using CEABAC10 transgenic mice. Cell proliferation was analyzed by real-time mRNA quantification of PCNA and immunohistochemistry staining of Ki67. RESULTS: Analysis of mucosa-associated E. coli from colon cancer and diverticulosis specimens showed that whatever the origin of the E. coli strains, 86% of cyclomodulin-positive E. coli belonged to B2 phylogroup and most harbored polyketide synthase (pks) island, which encodes colibactin, and/or cytotoxic necrotizing factor (cnf) genes. In vitro assays using I-407 intestinal epithelial cells revealed that mucosa-associated B2 E. coli strains were poorly adherent and invasive. However, mucosa-associated B2 E. coli similarly to Crohn’s disease-associated E. coli are able to induce CEACAM6 expression in T84 intestinal epithelial cells. In addition, in vivo experiments using a chronic infection model of CEACAM6 expressing mice showed that B2 E. coli strain 11G5 isolated from colon cancer is able to highly persist in the gut, and to induce colon inflammation, epithelial damages and cell proliferation. CONCLUSION: In conclusion, these data bring new insights into the ability of E. coli isolated from patients with colon cancer to establish persistent colonization, exacerbate inflammation and

The prevention of congenital toxoplasmosis is based on providing information to women, serologic diagnosis and treatment of the infected mother and child. In this article we present the results of 12 years of implementation of a congenital toxoplasmosis prevention program in which we measured the mother's infection incidence rate, the transmission rate and the number and severity of infection in newborns. The study was performed on 12035 pregnant women in the period 2000-2011. The prevalence rate of antibodies against Toxoplasma gondii was 18.33% (2206/12035). Thirty-seven out of 9792 susceptible women presented acute infection and the mother's infection incidence rate was 3.78 per 1000 births. The transplacental transmission rate was 5.4% (2/37). Two newborns presented congenital toxoplasmosis infection, one had no clinical signs while the other presented strabismus and chorioretinitis. Thirty-five infected mothers and the two children with congenital infection were treated. The transmission rates obtained allow consider this prevention program as a valid resource to minimize the impact of congenital toxoplasmosis.

Boron neutron capture therapy (BNCT) is based on selective accumulation of B-10 carriers in tumor followed by neutron irradiation. We demonstrated, in 2001, the therapeutic effect of BNCT mediated by BPA (boronophenylalanine) in the hamster cheek pouch model of oral cancer, at the RA-6 nuclear reactor. Between 2007 and 2011, the RA-6 was upgraded, leading to an improvement in the performance of the BNCT beam (B2 configuration). Our aim was to evaluate BPA-BNCT radiotoxicity and tumor control in the hamster cheek pouch model of oral cancer at the new "B2" configuration. We also evaluated, for the first time in the oral cancer model, the radioprotective effect of histamine against mucositis in precancerous tissue as the dose-limiting tissue. Cancerized pouches were exposed to: BPA-BNCT; BPA-BNCT + histamine; BO: Beam only; BO + histamine; CONTROL: cancerized, no-treatment. BNCT induced severe mucositis, with an incidence that was slightly higher than in "B1" experiments (86 vs 67%, respectively). BO induced low/moderate mucositis. Histamine slightly reduced the incidence of severe mucositis induced by BPA-BNCT (75 vs 86%) and prevented mucositis altogether in BO animals. Tumor overall response was significantly higher in BNCT (94-96%) than in control (16%) and BO groups (9-38%), and did not differ significantly from the "B1" results (91%). Histamine did not compromise BNCT therapeutic efficacy. BNCT radiotoxicity and therapeutic effect at the B1 and B2 configurations of RA-6 were consistent. Histamine slightly reduced mucositis in precancerous tissue even in this overly aggressive oral cancer model, without compromising tumor control.

There have been few publications regarding the prevalence of congenital upper extremity anomalies and no recent reports from the United States. The purpose of this investigation was to examine the prevalence of congenital upper extremity anomalies in the total birth population of New York State over a 19-year period utilizing the New York Congenital Malformations Registry (NYCMR) database. The NYCMR includes children with at least 1 birth anomaly diagnosed by 2 years of age and listed by diagnosis code. We scrutinized these codes for specific upper extremity anomalies, including polydactyly, syndactyly, reduction defects, clubhand malformations, and syndromes with upper limb anomalies. We included children born between 1992 and 2010. There were a total of 4,883,072 live births in New York State during the study period. The overall prevalence of congenital upper extremity anomalies was 27.2 cases per 10,000 live births. Polydactyly was most common with 12,418 cases and a prevalence rate of 23.4 per 10,000 live births. The next most common anomalies included syndactyly with 627 cases affecting the hands (1498 total) and reduction defects (1111 cases). Specific syndromes were quite rare and were noted in a total of 215 live births. The prevalence of anomalies was higher in New York City compared with New York State populations at 33.0 and 21.9 per 10,000 live births, respectively. The NYCMR data demonstrate that congenital upper extremity anomalies are more common than previously reported. This is in large part due to the high prevalence of polydactyly. Although registries are imperfect, such data are helpful in monitoring prevalence rates over time, identifying potential causes or associations, and guiding health care planning and future research.

OBJECTIVE: To review the relationship between congenital heart defects and chromosomal abnormalities detected by the karyotype. DATA SOURCES: Scientific articles were searched in MEDLINE database, using the descriptors "karyotype" OR "chromosomal" OR "chromosome" AND "heart defects, congenital". The research was limited to articles published in English from 1980 on. DATA SYNTHESIS: Congenital heart disease is characterized by an etiologically heterogeneous and not well understood group of lesions. Several researchers have evaluated the presence of chromosomal abnormalities detected by the karyotype in patients with congenital heart disease. However, most of the articles were retrospective studies developed in Europe and only some of the studied patients had a karyotype exam. In this review, only one study was conducted in Latin America, in Brazil. It is known that chromosomal abnormalities are frequent, being present in about one in every ten patients with congenital heart disease. Among the karyotype alterations in these patients, the most important is the trisomy 21 (Down syndrome). These patients often have associated extra-cardiac malformations, with a higher risk of morbidity and mortality, which makes heart surgery even more risky. CONCLUSIONS: Despite all the progress made in recent decades in the field of cytogenetic, the karyotype remains an essential tool in order to evaluate patients with congenital heart disease. The detailed dysmorphological physical examination is of great importance to indicate the need of a karyotype. PMID:25119760

Summary: Congenital symmastia is a medial confluence of the breasts. It is a rare anomaly with few reports in the literature and no standard treatment. In this article, we present a case of congenital symmastia treated by 3 steps: liposuction, fixation of the skin to the chest wall in the area of the intermammary sulcus, and postoperative intermammary compression. A successful result was achieved with normal cleavage between the breasts. So, this is considered the ideal treatment for this condition. PMID:28293510

Brain structure is changed in congenital anosmia.

Olfactory function in healthy people correlates with structural features of both the olfactory bulb and higher order olfactory processing areas, but we do not yet know how congenital anosmia affects these latter structures. In order to examine this question closer, we acquired T1 weighted magnetic resonance images from 17 subjects with congenital anosmia and from 17 age- and sex-matched controls. We compared white and gray matter volumes as well as cortical thickness between both groups. We found subjects with congenital anosmia to exhibit larger gray matter volumes in the left entorhinal and piriform cortices. Further, they had thicker orbitofrontal cortices bilaterally. Their left piriform cortex was also thicker than that of controls. These findings are in contrast to those observed in acquired anosmia, where reduced olfactory function is associated with reduced volumes and thickness. However, they fit well with observations from other sensory systems, e.g., vision, where congenital sensory loss is associated with a thicker primary cortex. This finding has been attributed to reduced or absent synaptic pruning as a result of missing peripheral sensory input. Our findings suggest that similar mechanisms take place in the olfactory system. © 2013.

The association between congenital facial paralysis and visual development has not been thoroughly studied. Of 27 pediatric cases of congenital facial paralysis, we identified 3 patients who developed amblyopia, a visual acuity decrease caused by abnormal visual development, as comorbidity. These 3 patients had facial paralysis in the periocular region and developed amblyopia on the paralyzed side. They started treatment by wearing an eye patch immediately after diagnosis and before the critical visual developmental period; all patients responded to the treatment. Our findings suggest that the incidence of amblyopia in the cases of congenital facial paralysis, particularly the paralysis in the periocular region, is higher than that in the general pediatric population. Interestingly, 2 of the 3 patients developed anisometropic amblyopia due to the hyperopia of the affected eye, implying that the periocular facial paralysis may have affected the refraction of the eye through yet unspecified mechanisms. Therefore, the physicians who manage facial paralysis should keep this pathology in mind, and when they see pediatric patients with congenital facial paralysis involving the periocular region, they should consult an ophthalmologist as soon as possible. © 2016 S.

The term congenital neutropenia encompasses a family of neutropenic disorders, both permanent and intermittent, severe (<0.5 G/l) or mild (between 0.5-1.5 G/l), which may also affect other organ systems such as the pancreas, central nervous system, heart, muscle and skin. Neutropenia can lead to life-threatening pyogenic infections, acute gingivostomatitis and chronic parodontal disease, and each successive infection may leave permanent sequelae. The risk of infection is roughly inversely proportional to the circulating polymorphonuclear neutrophil count and is particularly high at counts below 0.2 G/l.When neutropenia is detected, an attempt should be made to establish the etiology, distinguishing between acquired forms (the most frequent, including post viral neutropenia and auto immune neutropenia) and congenital forms that may either be isolated or part of a complex genetic disease.Except for ethnic neutropenia, which is a frequent but mild congenital form, probably with polygenic inheritance, all other forms of congenital neutropenia are extremely rare and have monogenic inheritance, which may be X-linked or autosomal, recessive or dominant.About half the forms of congenital neutropenia with no extra-hematopoietic manifestations and normal adaptive immunity are due to neutrophil elastase (ELANE) mutations.

Determine the prevalence of intraventricular hemorrhage in infants with moderate to severe congenital heart disease, investigate the impact of gestational age, cardiac diagnosis, and cardiac intervention on intraventricular hemorrhage, and compare intraventricular hemorrhage rates in preterm infants with and without congenital heart disease. A single-center retrospective review. A tertiary care children's hospital. All infants admitted to St. Louis Children's Hospital from 2007 to 2012 with moderate to severe congenital heart disease requiring cardiac intervention in the first 90 days of life and all preterm infants without congenital heart disease or congenital anomalies/known genetic diagnoses admitted during the same time period. None. Cranial ultrasound data were reviewed for presence/severity of intraventricular hemorrhage. Head CT and brain MRI data were also reviewed in the congenital heart disease infants. Univariate analyses were undertaken to determine associations with intraventricular hemorrhage, and a final multivariate logistic regression model was performed. There were 339 infants with congenital heart disease who met inclusion criteria and 25.4% were born preterm. Intraventricular hemorrhage was identified on cranial ultrasound in 13.3% of infants, with the majority of intraventricular hemorrhage being low-grade (grade I/II). The incidence increased as gestational age decreased such that intraventricular hemorrhage was present in 8.7% of term infants, 19.2% of late preterm infants, 26.3% of moderately preterm infants, and 53.3% of very preterm infants. There was no difference in intraventricular hemorrhage rates between cardiac diagnoses. Additionally, the rate of intraventricular hemorrhage did not increase after cardiac intervention, with only three infants demonstrating new/worsening high-grade (grade III/IV) intraventricular hemorrhage after surgery. In a multivariate model, only gestational age at birth and African-American race were predictors

The clinical presentation of congenital portosystemic shunt is variable and gastrointestinal bleeding is an uncommon presentation. To describe the imaging features of congenital portosystemic shunt as it presented in 11 children with (n = 6) and without gastrointestinal bleeding (n = 5). We performed a retrospective study on a clinical and imaging dataset of 11 children diagnosed with congenital portosystemic shunt. A total of 11 children with congenital portosystemic shunt were included in this study, 7 with extrahepatic portosystemic shunts and 4 with intrahepatic portosystemic shunts. Six patients with gastrointestinal bleeding had an extrahepatic portosystemic shunt, and the imaging results showed that the shunts originated from the splenomesenteric junction (n = 5) or splenic vein (n = 1) and connected to the internal iliac vein. Among the five cases of congenital portosystemic shunt without gastrointestinal bleeding, one case was an extrahepatic portosystemic shunt and the other four were intrahepatic portosystemic shunts. Most congenital portosystemic shunt patients with gastrointestinal bleeding had a shunt that drained portal blood into the iliac vein via an inferior mesenteric vein. This type of shunt was uncommon, but the concomitant rate of gastrointestinal bleeding with this type of shunt was high.

Potential implications of the helical heart in congenital heart defects.

The anatomic and functional observations made by Francisco Torrent-Guasp, in particular his discovery of the helical ventricular myocardial band (HVMB), have challenged what has been taught to cardiologists and cardiac surgeons over centuries. A literature debate is ongoing, with interdependent articles and comments from supporters and critics. Adequate understanding of heart structure and function is obviously indispensable for the decision-making process in congenital heart defects. The HVMB described by Torrent-Guasp and the potential impact on the understanding and treatment of congenital heart defects has been analyzed in the following settings: embryology, ventriculo-arterial discordance (transposition of great arteries), Ebstein's anomaly, pulmonary valve regurgitation after repair of tetralogy of Fallot, Ross operation, and other congenital heart defects. The common structural spiral feature is only one of the elements responsible for the functional interaction of right and left ventricles, and understanding the form/function relationship in congenital heart defects is more difficult than for acquired heart disease because of the variety and complexity of congenital heart defects. Individuals involved in the care of patients with congenital heart defects have to be stimulated to consider further investigations and alternative surgical strategies.

Yuan SM. Congenital heart defects in Williams syndrome. Turk J Pediatr 2017; 59: 225-232. Williams syndrome (WS), also known as Williams-Beuren syndrome, is a rare genetic disorder involving multiple systems including the circulatory system. However, the etiologies of the associated congenital heart defects in WS patients have not been sufficiently elucidated and represent therapeutic challenges. The typical congenital heart defects in WS were supravalvar aortic stenosis, pulmonary stenosis (both valvular and peripheral), aortic coarctation and mitral valvar prolapse. The atypical cardiovascular anomalies include tetralogy of Fallot, atrial septal defects, aortic and mitral valvular insufficiencies, bicuspid aortic valves, ventricular septal defects, total anomalous pulmonary venous return, double chambered right ventricle, Ebstein anomaly and arterial anomalies. Deletion of the elastin gene on chromosome 7q11.23 leads to deficiency or abnormal deposition of elastin during cardiovascular development, thereby leading to widespread cardiovascular abnormalities in WS. In this article, the distribution, treatment and surgical outcomes of typical and atypical cardiac defects in WS are discussed.

This article reviews the challenges in caring for individuals with congenital heart disease in developing countries and is drawn in part from the author's Presidential Address to the American Association for Thoracic Surgery in Philadelphia, May 2006. Economic globalization is resulting in demographic and lifestyle changes which are increasing the incidence of ischemic heart disease worldwide. A massive expansion of cardiothoracic surgery in developing countries is beginning. Although the rate of coronary surgery is contracting in Western countries, the population bulge that is approaching 65 years of age will also stretch surgical manpower and resources in developed countries within 10 to 20 years. The incidence of congenital heart disease is stable, but earlier and more accurate diagnosis is rapidly increasing the numbers of children needing the services of a congenital cardiac surgery team. Many opportunities for philanthropy are available, but care should be taken to assist in the most meaningful way by working with a long-term educational program and avoiding surgical tourism.

Effect of the black tea extracted from a mangrove plant species, Ceriops decandra (Griff.) was studied on dimethyl benz[a]anthracene (DMBA)-induced changes in blood hematology and plasma non-enzymatic antioxidants in male hamsters. Hamsters were painted with 0.5% solution of DMBA in liquid paraffin on the right buccal pouch three times in a week up to 14 weeks. Each application treated with 0.4mg of DMBA. The mangrove black tea extract (MBTE) was administrated orally with 5mgkg(-1) twice a day and then with DMBA on alternate days. Results showed that the DMBA caused a significant (P<0.05) decline in the levels of reduced glutathione (GSH), vitamin-C, -E, red blood cells, hemoglobin, mean corpuscular volume and hematocrit; and increase in the levels of WBC, platelets, lymphocytes and neutrophils. The MBTE prevented the DMBA-induced adverse changes significantly in blood and biochemical parameters of the male hamsters. This work concluded that the black tea extracted from the coastal mangrove species C. decandra prevented the DMBA-induced buccal pouch carcinogenesis in hamsters. Copyright © 2011 Elsevier B.V.

Congenital factor VII (FVII) deficiency is the commonest type of the rare bleeding disorders. Very few cases of congenital FVII deficiency developed inhibitor and liver transplant is considered as definitive treatment. In the literature, twelve patients with congenital FVII deficiency developed inhibitors. Two had spontaneous resolution of inhibitors and one did not respond to high dose recombinant factor VIIa (rFVIIa) and died. Regarding liver transplant in congenital FVII patients, seven patients underwent liver transplant with good prognosis. We report a 5-year-old girl with confirmed severe congenital FVII deficiency since neonatal period. She suffered from recurrent intracranial bleeding despite rFVIIa replacement. After auxiliary liver transplant at the age of 4, she continued to show persistent deranged clotting profile and was found to have inhibitor towards FVII. Interestingly, she was still responsive to rFVIIa replacement. © 2016 John Wiley & Sons Ltd.

Congenital pituitary hypothyroidism (pituitary cretinism) results in severe mental and growth retardation when it is not treated soon after birth. Since the introduction of neonatal mass screening of thyrotropin (TSH), most congenital hypothyroidism has been detected except for pituitary and hypothalamic hypothyroidism. In 1971, we reported the first familial case of congenital isolated TSH deficiency and thereafter began intensively investigating the molecular pathology of congenital pituitary hypothyroidism. After determining the entire structure of the human TSH beta gene, we identified the molecular pathology in this patient. Recently, we reported a familial case of congenital combined pituitary hormone deficiency (PIT1 abnormality). To examine the PIT1 gene, which encodes pituitary specific transcription factor, Pit-1/GHF-1, we determined its genomic structure. Sequence comparisons using PCR amplified PIT1 gene sequences revealed only one nonsense mutation in the patient, and established that this alteration caused the combined deficiencies of TSH, GH and PRL. We also discuss other recent progress in molecular pathology of congenital pituitary hypothyroidism.

The chemopreventive efficacy of turmeric has been established in experimental systems. However, its mechanism(s) of action are not fully elucidated in vivo. The present study investigates the mechanism of turmeric-mediated chemoprevention in 7,12-dimethylbenz(a)anthracene (DMBA)-induced hamster buccal pouch (HBP) carcinogenesis at 2, 4, 6, 10 and 12 weeks. Dietary turmeric (1%) led to decrease in DMBA-induced tumor burden and multiplicity, and enhanced the latency period in parallel, to its modulatory effects on oncogene products and various cellular responses during HBP tumorigenesis. DMBA-induced expression of ras oncogene product, p21 and downstream target, the mitogen-activated protein kinases were significantly decreased by turmeric duringmore » HBP carcinogenesis. Turmeric also diminished the DMBA-induced mRNA expression of proto-oncogenes (c-jun, c-fos) and NF-{kappa}B, leading to decreased protein levels and in further attenuation of DMBA-induced AP-1/NF-{kappa}B DNA-binding in the buccal pouch nuclear extracts. Besides, buccal pouch of hamsters receiving turmeric diet showed significant alterations in DMBA-induced effects: (a) decrease in cell proliferation (diminished PCNA and Bcl2 expression), (b) enhanced apoptosis (increased expression of Bax, caspase-3 and apoptotic index), (c) decrease in inflammation (levels of Cox-2, the downstream target of AP-1/NF-{kappa}B, and PGE2) and (d) aberrant expression of differentiation markers, the cytokeratins (1, 5, 8, and 18). Together, the protective effects of dietary turmeric converge on augmenting apoptosis of the initiated cells and decreasing cell proliferation in DMBA-treated animals, which in turn, is reflected in decreased tumor burden, multiplicity and enhanced latency period. Some of these biomarkers are likely to be helpful in monitoring clinical trials and evaluating drug effect measurements.« less

Quantitative measurement of feline colonic transit

Colonic transit scintigraphy, a method for quantitatively evaluating the movement of the fecal stream in vivo, was employed to evaluate colonic transit in the cat. Scintigraphy was performed in duplicate in five cats and repeated four times in one cat. After instillation of an 111In marker into the cecum through a surgically implanted silicone cecostomy tube, colonic movement of the instillate was quantitated for 24 h using gamma scintigraphy. Antegrade and retrograde motion of radionuclide was observed. The cecum and ascending colon emptied rapidly, with a half-emptying time of 1.68 +/- 0.56 h (mean +/- SE). After 24 h, 25.1more » +/- 5.2% of the activity remained in the transverse colon. The progression of the geometric center was initially rapid, followed later by a delayed phase. Geometric center reproducibility was found to be high when analyzed using simple linear regression (slope = 0.92; r = 0.73; P less than 0.01). Atropine (0.1 mg/kg im) was found to delay cecum and ascending colon emptying and delay progression of the geometric center. These results demonstrate both 1) the ability of colonic transit scintigraphy to detect changes in transit induced by pharmacological manipulation and 2) the fact that muscarinic blockade inhibits antegrade transit of the fecal stream. We conclude that feline colonic transit may be studied in a quantitative and reproducible manner with colonic transit scintigraphy.« less

The broad range of relatively rare procedures performed in pediatric cardiac catheterization laboratories has made the standardization of care and risk assessment in the field statistically quite problematic. However, with the growing number of patients who undergo cardiac catheterization, it has become imperative that the cardiology community overcomes these challenges to study patient outcomes. The Congenital Cardiac Catheterization Project on Outcomes was able to develop benchmarks, tools for measurement, and risk adjustment methods while exploring procedural efficacy. Based on the success of these efforts, the collaborative is pursuing a follow-up project, the Congenital Cardiac Catheterization Project on Outcomes-Quality Improvement, aimed at improving the outcomes for all patients undergoing catheterization for congenital heart disease by reducing radiation exposure.

Mortality throughout early childhood for Michigan children born with congenital anomalies, 1992-1998.

Congenital anomalies are a leading cause of infant deaths, accounting for almost a fifth of all infant deaths. Few studies have researched the survival experience of infants born with congenital anomalies past the infant stage. Using birth and death files routinely linked to the Michigan Birth Defects Registry, we identified all singleton infants during calendar years 1992 through 1998 with reportable congenital anomalies for our study. A comparative file of children born without congenital anomalies during the same time period was developed using linked birth and death files. The mortality data were assessed by age at death (through age six) and race to determine mortality rates, relative risks, hazard ratios, and survival trends. Throughout early childhood, children born with congenital anomalies had a high risk of mortality compared with all other children. The overall 7-year hazard ratio comparing children with congenital anomalies with all other children was 7.2. Overall mortality rates for black children were significantly higher than white children through the age of seven, irrespective of whether they had congenital anomalies. Among children with congenital anomalies, this disparity disappeared after adjusting for birth weight, sex, mother's age, mother's education, and number of organ systems affected. Compared with children without congenital anomalies, children born with congenital anomalies had a higher risk of mortality well beyond the infant period. Racial disparities in mortality rates among children with congenital anomalies were due to confounding factors.

A case of congenital hyperthyroidism, after pregnancy complicated by Graves' disease is presented. Fetal tachycardia was the cardial symptom. Caesarean section was performed in the 29 years old patient with normal thyroid function in the 29th week of pregnancy. The neonate showed symptoms of a congenital hyperthyroidism with goitre. Antithyroid antibodies were found in the serum of both mother and child. At the age of ten weeks, after a short course of thyrostatic treatment, the infant was discharged with normal thyroid function following complicationfree progress.

The aim of this study is to assess the short-term outcome of intraoperative colonic irrigation and primary anastomosis and to suggest the usefulness of the procedure when a preoperative mechanical bowel preparation is inappropriate. This retrospective study included 38 consecutive patients (19 male patients) who underwent intraoperative colonic irrigation and primary anastomosis for left colon disease between January 2010 and December 2016. The medical records of the patients were reviewed to evaluate the patients' characteristics, operative data, and postoperative short-term outcomes. Twenty-nine patients had colorectal cancer, 7 patients had perforated diverticulitis, and the remaining 2 patients included 1 with sigmoid volvulus and 1 with a perforated colon due to focal colonic ischemia. A diverting loop ileostomy was created in 4 patients who underwent a low anterior resection. Complications occurred in 15 patients (39.5%), and the majority was superficial surgical site infections (18.4%). Anastomotic leakage occurred in one patient (2.6%) who underwent an anterior resection due sigmoid colon cancer with obstruction. No significant difference in overall postoperative complications and superficial surgical site infections between patients with obstruction and those with peritonitis were noted. No mortality occurred during the first 30 postoperative days. The median hospital stay after surgery was 15 days (range, 8-39 days). Intraoperative colonic irrigation and primary anastomosis seem safe and feasible in selected patients. This procedure may reduce the burden of colostomy in patients requiring a left colon resection with an inappropriate preoperative mechanical bowel preparation.

Etiology and Treatment of Congenital Festoons.

Festoons and malar bags present a particular challenge to the plastic surgeon and commonly persist after the traditional lower blepharoplasty. They are more common than we think and a trained eye will be able to recognize them. Lower blepharoplasty in these patients requires addressing the lid-cheek junction and midcheek using additional techniques such as orbicularis retaining ligament (ORL) and zygomaticocutaneous ligament (ZCL) release, midface lift, microsuction, or even direct excision (Kpodzo e al. in Aesthet Surg J 34(2):235-248, 2014; Goldberg et al. in Plast Reconstr Surg 115(5):1395-1402, 2005; Mendelson et al. in Plast Reconstr Surg 110(3):885-896, 2002). The goal in these patients is to restore a smooth contour from the lower eyelid to the cheek. The review of literature shows the need for more than one surgery for treatment of the festoons (Furnas in Plast Reconstr Surg 61(4):540-546, 1978). One of the reasons WHY these cases are so challenging is that the festoons tend to persist even after surgical treatment. As Furnas said, "Malar mounds have acquired some notoriety for their persistence in the face of surgical efforts to remove them" (Furnas in Clin Plast Surg 20(2):367-385, 1993). This could be due to different etiology between acquired and congenital festoons. There are currently no cases of congenital festoons described in the literature. In the last 10 years, we have treated a total of 59 patients with festoons or malar mounds. We used the terminology of festoon for acquired cases and malar mound for congenital ones (Kpodzo et al. 2014). We were successful with treating 56 patients who developed acquired festoons later on in life; however, three cases required an additional treatment to improve residual puffiness that they had after the first operation. From the above findings, we hypothesized that there should be something common in patients with congenital festoons or malar mounds which are different from acquired festoons. All of these

Background Chagas disease is caused by the parasite Trypanosoma cruzi and endemic in much of Latin America. With increased globalization and immigration, it is a risk in any country due in part to congenital transmission. The frequency of congenital transmission is unclear. Objective To assess the frequency of congenital transmission of T. cruzi. Search Strategy PubMed, Journals@Ovid Full Text, EMBASE, CINAHL, Fuente Academica and BIREME databases were searched using seven search terms related to Chagas disease or Trypanosoma cruzi and congenital transmission. Selection Criteria The inclusion criteria were the following: Dutch, English, French, Portuguese or Spanish language; case report, case series or observational study; original data on congenital T. cruzi infection in humans; congenital infection rate reported or it could be derived. This systematic review included 13 case reports/series and 51 observational studies. Data Collection and Analysis Two investigators independently collected data on study characteristics, diagnosis and congenital infection rate. The principal summary measure – the congenital transmission rate – is defined as the number of congenitally infected infants divided by the number of infants born to infected mothers. A random effects model was utilized. Main Results The pooled congenital transmission rate was 4.7% (95% confidence interval: 3.9–5.6%). Endemic countries had a higher rate of congenital transmission compared to non-endemic (5.0% vs. 2.7%). Conclusions Congenital transmission of Chagas disease is a global problem. Overall risk of congenital infection in infants born to infected mothers is about 5%. The congenital mode of transmission requires targeted screening to prevent future cases of Chagas disease.

Colonic schwannomas are very rare gastrointestinal tumours originating from Schwann cells, which form the neural sheath. Primary schwannomas of the lower gastrointestinal tract are very rare and usually benign in nature. However, if they are not surgically removed, malign degeneration can occur. We report a case of a 79-year-old woman who presented to our clinic with rectal bleeding and constipation. She underwent a lower gastrointestinal tract endoscopy. A mass subtotally obstructing the lumen of the sigmoid colon was seen and biopsies were taken. Histopathological examination indicated a suspicion of gastrointestinal tumour and the patient underwent sigmoid colon resection after preoperative evaluation by laboratory analysis, abdominal ultrasonography and CT. Her postoperative course was uneventful and she was discharged on the fifth day for outpatient control. The histopathology report revealed schwannoma of the sigmoid colon. This was a case of schwannoma of the sigmoid colon that was successfully treated with total resection. PMID:25976197

Colonic strictures: dilation and stents.

PubMed

Adler, Douglas G

2015-04-01

Colonic strictures, both benign and malignant, are commonly encountered in clinical practice. Benign strictures are most commonly treated by balloon dilation and less frequently with stents. Balloon dilation can help forestall or obviate surgery in some patients. Colonic strictures of malignant etiology generally need to be managed by stents and/or surgery. This article reviews endoscopic approaches to the management of colonic strictures. Copyright © 2015 Elsevier Inc. All rights reserved.

Many studies show that congenital defects in infants conceived by assisted reproductive techniques (ART) are more than infants of normal conception (NC). The aim of this study is to determine the frequency of congenital anomalies in ART infants from Royan Institute and to compare congenital anomalies between two ART techniques.  In a cross-sectional descriptive study, 400 ART infants from Royan Institute who resided in Tehran were selected by non-random, consecutive sampling. Infants were examined twice (until 9 months of age) by a pediatrician. Infants' congenital anomalies were described by each body system or organ and type of ART. Data were analyzed by SPSS version 16 and Fisher's exact test. The frequency of different organ involvement in the two examinations were: 40 (10%) skin, 25 (6.2%) urogenital system, 21 (5.2%) gastrointestinal tract, 13 (3.2%) visual, and 8 (2%) cardiovascular system. Major congenital defects in infants conceived by in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) were hypospadiasis, inguinal hernia, patent ductus arteriosus plus ventricular septal defect (PDA + VSD), developmental dysplasia of the hip, lacrimal duct stenosis during the first year of life, hydronephrosis and urinary reflux over grade III, undescending testis, ureteropelvic junction stenosis, and torticoli. Two-thirds of ART infants had no defects. A total of 7% of IVF and ICSI infants had one of the major abovementioned congenital anomalies. This rate was higher than NC infants (2%-3%). There was no difference between the ICSI and IVF group.

Maternal reproductive history and the risk of isolated congenital malformations.

We examined the relationship between maternal reproductive history and the newborn's risk of isolated congenital malformations in a large case-control cohort from the Polish Registry of Congenital Malformations. Congenital malformations were classified into four categories: isolated congenital heart defects (n=1673), isolated cleft palate (n=255), cleft lip with or without cleft palate (n=448) and renal agenesis (n=103). The case groups were compared with a shared group of 2068 controls recruited in the same time period and geographic area. Multivariable logistic regression was used to assess the risk associated with maternal gravidity and of previous miscarriages after accounting for maternal age and other potential risk factors. In unadjusted analyses, maternal gravidity was significantly associated with increased risk of all four classes of congenital malformations. After adjustment, a significant association persisted for congenital heart defects [odds ratio (OR)=1.22, [95% confidence interval (CI) 1.09, 1.36], P=0.0007] and cleft lip with or without cleft palate (OR=1.21, [95% CI 1.09, 1.36], P=0.0005). A similar trend existed for isolated cleft palate (OR=1.18, [95% CI 1.02, 1.37], P=0.03). There was no appreciable increase in the risk of congenital malformations associated with a maternal history of miscarriages, but a trend for a protective effect on the occurrence of cleft lip with or without cleft palate was observed (OR=0.72, [95% CI 0.52, 0.99], P=0.045). Based on our data, maternal gravidity represents a significant risk factor for congenital heart defects and cleft lip with or without cleft palate in the newborn infant. Our data do not support an increase in risk because of past history of miscarriages. © 2011 Blackwell Publishing Ltd.

Inorganic arsenic can get easily through the placenta however there are very few human data on congenital anomalies related to arsenic exposure. Objective of our study was to explore the associations between arsenic content of drinking water and prevalence of some congenital anomalies. Four anomalies reported to the Hungarian Congenital Anomalies Registry between 1987 and 2003 were chosen to be analysed in relation to arsenic exposure: congenital anomalies of the circulatory system (n=9734) were considered as cases, while Down syndrome, club foot and multiple congenital malformations were used as controls (n=5880). Arsenic exposure of the mothers during pregnancy was estimated by using archive measurement data for each year and for each settlement where the mothers lived. Analysis of the associations between the prevalence of congenital heart anomalies and arsenic exposure during pregnancy was performed by logistic regression. The child's gender and age of the mother were adjusted for. The associations were evaluated by using the present EU health limit value of 10.0 μg/L arsenic concentration as a cut-off point. Regular consumption of drinking water with arsenic concentration above 10 μg/L during pregnancy was associated with an increased risk of congenital heart anomalies in general (adjusted OR=1.41; 95% C.I.: 1.28-1.56), and especially that of ductus Botalli persistens (adjusted OR=1.81, 95%C.I.: 1.54-2.11) and atrial septal defect (adjusted OR=1.79; 95%C.I.: 1.59-2.01). The presented results showed an increased risk of congenital heart anomalies among infants whose mothers were exposed to drinking water with arsenic content above 10 μg/L during pregnancy. Further studies of possible similar effects of concentrations below 10 μg/L are warranted. Copyright © 2014 Elsevier GmbH. All rights reserved.

Interventional Cardiology for Congenital Heart Disease

PubMed Central

2018-01-01

Congenital heart interventions are now replacing surgical palliation and correction in an evolving number of congenital heart defects. Right ventricular outflow tract and ductus arteriosus stenting have demonstrated favorable outcomes compared to surgical systemic to pulmonary artery shunting, and it is likely surgical pulmonary valve replacement will become an uncommon procedure within the next decade, mirroring current practices in the treatment of atrial septal defects. Challenges remain, including the lack of device design focused on smaller infants and the inevitable consequences of somatic growth. Increasing parental and physician expectancy has inevitably lead to higher risk interventions on smaller infants and appreciation of the consequences of these interventions on departmental outcome data needs to be considered. Registry data evaluating congenital heart interventions remain less robust than surgical registries, leading to a lack of insight into the longer-term consequences of our interventions. Increasing collaboration with surgical colleagues has not been met with necessary development of dedicated equipment for hybrid interventions aimed at minimizing the longer-term consequences of scar to the heart. Therefore, great challenges remain to ensure children and adults with congenital heart disease continue to benefit from an exponential growth in minimally invasive interventions and technology. This can only be achieved through a concerted collaborative approach from physicians, industry, academia and regulatory bodies supporting great innovators to continue the philosophy of thinking beyond the limits that has been the foundation of our specialty for the past 50 years.

The Adult Congenital and Pediatric Cardiology (AC/PC) Section was established to develop a clear voice within the American College of Cardiology and address the myriad issues facing the congenital heart disease profession. The Section is governed by the AC/PC Council, which includes pediatric cardiologists, adult congenital cardiologists, a cardiac care associate, and a fellow-in-training member. The Council is responsible for bidirectional communication between the College's Board of Trustees and the AC/PC Section members. Since its founding in 2004, Section objectives have been defined by the College's mission: to advocate for quality cardiovascular care through education, research promotion, and the development and application of standards and guidelines and to influence health care policy. The pillars of the College-advocacy, quality, education, and member engagement-serve as the defining template for the Section's strategy. The Section has developed work groups in advocacy, clinical practice, education and training, quality, and publications. A separate leadership group has been developed for adult congenital heart disease. Work groups are open to all Section members. Recognition of the importance of lifelong care in congenital heart disease led Section leaders to incorporate pediatric cardiology and adult congenital heart disease content into each of the work groups. There are more than 1,200 Section members, with nearly 400 members actively contributing to Section activities. This article outlines Section efforts to date and highlights significant successes to date. Copyright © 2012 American College of Cardiology Foundation. Published by Elsevier Inc.

To perform a genotype-phenotype correlation study in an X-linked congenital idiopathic nystagmus pedigree (pedigree 1) and to assess the allelic variance of the FRMD7 gene in congenital idiopathic nystagmus. Subjects from pedigree 1 underwent detailed clinical examination including nystagmology. Screening of FRMD7 was undertaken in pedigree 1 and in 37 other congenital idiopathic nystagmus probands and controls. Direct sequencing confirmed sequence changes. X-inactivation studies were performed in pedigree 1. The nystagmus phenotype was extremely variable in pedigree 1. We identified 2 FRMD7 mutations. However, 80% of X-linked families and 96% of simplex cases showed no mutations. X-inactivation studies demonstrated no clear causal link between skewing and variable penetrance. We confirm profound phenotypic variation in X-linked congenital idiopathic nystagmus pedigrees. We demonstrate that other congenital nystagmus genes exist besides FRMD7. We show that the role of X inactivation in variable penetrance is unclear in congenital idiopathic nystagmus. Clinical Relevance We demonstrate that phenotypic variation of nystagmus occurs in families with FRMD7 mutations. While FRMD7 mutations may be found in some cases of X-linked congenital idiopathic nystagmus, the diagnostic yield is low. X-inactivation assays are unhelpful as a test for carrier status for this disease.

Mental and behavioral disorders among people with congenital deafblindness.

The population of people with congenital deafblindness faces challenges concerning communication and mobility. Due to the significance of the sensory loss it is difficult to diagnose mental and behavioral disorders. This article investigates the prevalence of mental and behavioral disorders among 95 congenitally deafblind adults. Seventy-four percent were found to have a mental and/or behavioral diagnose. Mental retardation was found among 34%, psychosis among 13%. Mental and behavioral disorders, especially with symptoms of psychosis and mental retardation, are common among people with congenital deafblindness. Clinical experience is needed, as well as cross-disciplinary cooperation and specialized diagnostic methods together with a observation and intervention period in order to be able to assess and differentiate mental and behavioral symptoms from sensory deprivation in people with congenital deafblindness.

The aim of this study was to assess the prevalence of congenital defects observed in patients with Prader-Willi syndrome (PWS) and to compare this prevalence with that described in the general population. In addition, these findings were correlated with the different etiologic subtypes. A total of 180 children with PWS followed for 13 years were included in this study. Diagnosis was confirmed by the methylation test, and genetic subtypes were established by using fluorescence in situ hybridization or multiplex ligation-dependent probe amplification and microsatellite analyses. The prevalence of congenital defects was compared with national and international registries of congenital defects in the general population (Estudio Colaborativo Latinoamericano de Malformaciones Congénitas, European Surveillance of Congenital Anomalies, and the New York Registry). Twenty-two percent of the patients presented congenital defects with a risk of 5.4 to 18.7 times higher than that of the general population. The most frequent congenital defects were heart defects, renoureteral malformations, vertebral anomalies, hip dysplasia, clubfoot, and agenesis/hypoplasia of the corpus callosum. Each of these congenital defects was significantly more frequent in the children with PWS than in the general population. The congenital heart defects were more frequent in girls than in boys with PWS. No significant differences were found when the defects were correlated with the different etiologic subtypes. An increased prevalence of congenital defects was found in our PWS patients. This finding suggests the need for further studies in PWS children that allow physicians to detect the congenital defects found in this series and, thus, to anticipate complications, with the ultimate aim of enhancing the management of PWS patients.
