Ciliates of the genus Gruberia are poorly studied. Consequently, most species lack detailed morphological descriptions, and all gene sequences in GenBank are not classified at the species level. In this study, a detailed morphological description of a population of G. lanceolata from Brazil is presented, based on live and protargol-stained organisms. We also present the 18S rRNA gene sequence and the phylogenetic position of this species. The primary characteristics of G. lanceolata from the Maricá Lagoon are as follows: an elongate fusiform body 280-870 × 40-160 μm in size; rosy cortical granules; a peristome occupying approximately 1/3-1/2 of body length; an adoral zone comprising 115-330 membranelles; a paroral membrane in 35-50 fragments; and a moniliform macronucleus with 11-16 nodules...

BACKGROUND: Previous meta-analyses of randomised controlled trials (RCTs) have suggested a reduction in parastomal hernias (PSH) with prophylactic mesh. However, concerns persist regarding variably supportive evidence and cost. We performed an updated systematic review and meta-analysis to inform a novel cost-effectiveness analysis. METHODS: The PubMed, EMBASE and Cochrane Centre Register of Controlled Trials databases were searched (February 2018). We included RCTs assessing mesh reinforcement during stoma formation...

Fecal diversion with ostomy construction can be a temporary or definitive surgical measure for the treatment of refractory inflammatory bowel disease (IBD). However, the fecal diversion surgery is associated with various stoma, peristomal complications, and recurrence or occurrence of de novo small bowel Crohn's disease (CD). Stoma complications often need enterostomal therapy or surgical revision. Peristomal cutaneous lesions, such as pyoderma gangrenosum, usually require immunomodulator or biological therapy...

Liquid drops impacting on a solid surface is a familiar phenomenon. On rainy days, it is quite important for leaves to drain off impacting raindrops. Water can bounce off or flow down a water-repellent leaf easily, but with difficulty on a hydrophilic leaf. Here, we show an interesting phenomenon in which impacting drops on the hydrophilic pitcher rim of Nepenthes alata can spread outward to prohibit water filling the pitcher tank. We mimic the peristome surface through a designed 3D printing and replicating way and report a time-dependently switchable liquid transport based on biomimetic topological structures, where surface curvature can work synergistically with the surface microtextures to manipulate the switchable spreading performance...

Two new species of cheilostome Bryozoa are described from the Faroe Islands archipelago. Cinclidia aculeata n. gen. et sp. is a new cribrilinid taxon, distinguished from other cribrimorphs by the skeletal characters of the frontal shield and ooecium, and the absence of avicularia. A second new species, Turbicellepora faroensis n. sp., is distinguished by the shape of the orificial sinus, peristome, and suboral and interzooidal avicularia as well as by the presence of distolateral, tube-shaped adventitious avicularia (paired or single)...

Introduction  To prevent or diminish pulmonary problems in laryngectomized patients, continuous use of a heat and moisture exchanger (HME) is recommended. Therefore, automatic speaking valves are also often combined with an HME to enable hands-free speech. In order to keep these devices in place, most commonly, peristomal patches are used. Objective  This prospective clinical 2 × 2 crossover study aims at assessing the added value of a new patch for HME application, the Provox StabiliBase OptiDerm (SBO)...

BACKGROUND: Enteral nutrition (EN) is a safe and cost-effective intervention with significant morbidity and mortality benefit that can also be associated with complications. Peristomal infections can occur in 5%-30% of cases after percutaneous endoscopic gastrostomy placement. Despite this common occurrence, widespread use of objective diagnostic criteria is not prevalent, possibly leading to overuse of antibiotics. METHODS: All patients who were reporting symptoms consistent with peristomal infection were evaluated...

Peristomal skin problems represent one of the most common complications of a tracheostomy. A quasi-experimental study was conducted among patients ages 18 to 65 years hospitalized in a Turkish university hospital ear-nose-throat clinic between August 15, 2013, and December 15, 2013, to compare the effect of using or not using a barrier cream on the peristomal skin with regard to pH, moisture, temperature, color, odor, turgor, infections, and lesions after tracheostomy surgery. Patients were selected using a purposeful sampling method and included if they had not undergone another operation for a complication (eg, pneumothorax, tube misplacement, hemorrhage) within 24 hours following the tracheostomy operation...

OBJECTIVE: There are a limited number of studies examining the effects of products used in stoma care. This study compares the effects of 3 different methods of care on the peristomal skin integrity of children with percutaneous endoscopic gastrostomy (PEG) tubes. METHODS: In this randomized controlled study, 60 children were allocated to the 3 study groups (group 1: hydrogel, group 2: soap and water, group 3: saline solution). Dressings were changed daily for all groups during the first week, then weekly for group 1 and daily for groups 2 and 3...

Necrotizing fasciitis (NF) is a rare entity with its subacute form being even rarer. The condition has also been described to occur in the peristomal area in relation to different clinical scenarios. However, it has not been described in the setting of adjuvant chemotherapy where these medications have already been given. While the diagnosis may be delayed or missed due to the subtle symptomatology of the indolent subacute form of NF, another reason for a delayed or missed diagnosis may be the excessive use of tape and the stoma belt around the stomal appliance to prolong the life of the appliance beyond its recommended days of usage due to economic constraints...

Skin complications are common in people who have an ostomy, and often involve the skin's function as a barrier breaking down. Many products have been developed to prevent and treat complications. However, in developing countries, they may be too expensive for patients to buy or not be available. Three case studies found the use of rhassoul, an affordable clay that is readily available in Morocco, to manage peristomal skin damage and protect the skin. Its protective properties are believed to include its ability to absorb and neutralise substances in ostomy output that damage skin and to act as a barrier...

BACKGROUND: Ileostomy construction is a common procedure but can be associated with morbidity. The stoma is commonly secured to the skin using transcutaneous sutures. It is hypothesized that intracutaneous sutures result in a tighter adherence of the peristomal skin to the stoma plate to prevent faecal leakage. The study aimed to compare the effect of intracutaneous versus transcutaneous suturing of ileostomies on faecal leakage and quality of life. METHODS: This randomized trial was undertaken in 11 hospitals in the Netherlands...

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) placement is the modality of choice for long-term enteral nutrition in view of technical ease and cost-effectiveness. Peristomal infection (PI) remains the most common complication following PEG tube placement. The aim of this study was to assess the incidence and risk factors for PI and outline a microbiological profile that can aid in prophylactic and therapeutic strategies. METHODS: A retrospective study of 781 patients who underwent PEG placement (Cook PEG-Pull-S-20Fr/24Fr) from 2010 to 2015 at our tertiary care center were included...

Helminth parasites have been studied as potential accumulators for different pollutants. Echinostoma paraensei is a foodborne trematode whose vertebrate host, the rodent Nectomys squamipes, is naturally exposed to environmental pesticides. However, little information exists regarding the pesticide's effects on helminths. This study investigated the morphological effects on the trematode, E. paraensei, after experimental Roundup® herbicide exposure, in concentrations below those recommended for agricultural use...

Background and study aims:  Insertion of a percutaneous endoscopic gastrostomy (PEG) with push-through technique and T-fastener fixation (PEG-T) has recently been introduced in pediatric patients. The T-fasteners allow a primary insertion of a balloon gastrostomy. Due to limited data on the results of this technique in children, we have investigated peri- and postoperative outcomes after implementation of PEG-T in our department. Patients and methods:  This retrospective chart review included all patients below 18 years who underwent PEG-T placement from 2010 to 2014...

The ability to perform hygroscopic movements has evolved in many plant lineages and relates to a multitude of different functions such as seed burial, flower protection or regulation of diaspore release. In most mosses, spore release is controlled by hygroscopic movements of the peristome teeth and also of the spore capsule. Our study presents, for the first time, temporally and spatially well-resolved kinematic analyses of these complex shape changes in response to humidity conditions and provides insights into the sophisticated functional morphology and anatomy of the peristome teeth...
