Infections at the bottom end of the gastrointestinal tract

This article concentrates on specific infections of the distal gastrointestinal (GI) tract, particularly those that are transmitted sexually, by anal intercourse. Syphilis, gonorrhoea and lymphogranuloma venereum (LGV) are age old and well known diseases, but the features may be unfamiliar to GI histopathologists. Every histopathology trainee will have seen Herpes simplex virus (HSV) infection of squamous epithelium (e.g. oesophagus, vulva and anus), but the HSV pseudotumour of the anus/perineum can present a pitfall to those who have not previously encountered this entity. Another, more recently described, entity that has a predilection for the ano-rectal region is Epstein–Barr Virus (EBV) positive mucocutaneous ulcer, and this also presents a diagnostic trap to the unwary.     

Surgical technique in constructing the jejunojejunostomy and the risk of small bowel obstruction after Roux-en-Y gastric bypass

BackgroundMechanical problems at the level of the jejunojejunostomy (JJ) have been identified as a cause of small bowel obstruction (SBO) after laparoscopic Roux-en-Y gastric bypass (RYGB).ObjectivesThe objective of the study was to investigate associations between specific surgical techniques used to construct the JJ and the subsequent risk of SBO.SettingNationwide Registry, Sweden.MethodsThe risk of SBO after primary RYGB surgery during 2012–2019 was assessed using data from the Scandinavian Obesity Surgery Registry and the Swedish National Patient Register. The impact of unidirectional or bidirectional stapling and length of the mesenteric division (0, 1–4, or ≥5 cm) at the JJ was analyzed with adjustments for known covariates.ResultsWe analyzed outcomes from 23,448 patients (mean follow-up = 4.3 ± 2.2 yr). In multivariate analysis, bidirectional stapling of the JJ was associated with a reduced 30-day risk of SBO (hazard ratio [HR] = .52, 95% confidence interval [CI] = .29–.95, P < .05), whereas limited mesenteric division (1–4 cm) increased the risk of SBO (HR = 1.66, 95% CI = 1.14–2.42, P < .01). The long-term incidence of SBO was increased by bidirectional stapling but unaffected by mesenteric division. However, mesenteric division decreased the long-term risk of SBO in patients with a bidirectionally stapled JJ (1–4 cm, HR = .59, 95% CI = .38–.90, P < .05; ≥5 cm, HR = .30, 95% CI = .14–.65, P < .005).ConclusionsThe surgical technique for construction of the JJ may affect the incidence of SBO after RYGB surgery.

基于健康信念模式的护理干预在慢性牙周炎患者种植修复治疗中的应用

目的探讨基于健康信念模式(HBM)的护理干预在慢性牙周炎患者种植修复治疗中的应用效果。方法选取2018年6月至2019年5月我院行种植修复治疗的慢性牙周炎患者72例,随机平均分为两组。对照组采用常规护理及健康教育,观察组在此基础上行基于HBM的护理干预,比较两组的牙科焦虑、畏惧程度,种植体周围PLI、 SBI、 PD。结果干预后,观察组的DAS、 DFS评分低于对照组(P <0.05);干预后6个月,观察组种植体周围PLI、 SBI及PD均优于对照组(P <0.05)。结论基于HBM的护理干预能降低慢性牙周炎患者种植修复的焦虑和畏惧水平,显著改善临床疗效,促进种植体周围健康,值得临床推广。     

Protective equipment-related pressure ulcers in healthcare workers during COVID-19 pandemic: A systematic review

AimThis systematic review was carried out to examine pressure ulcers in healthcare staff due to the use of protective equipment during COVID-19 pandemic and the precautions taken to prevent these injuries.MethodRelevant studies were retrospectively searched. Seven English keywords identified from MESH were used while searching. The search was carried out in five international databases by trying various combinations of these words during February 15–25, 2021. This systematic review was updated by rescanning databases on December 20, 2021 and a total of 611 studies were attained.Results17 studies which met the study inclusion criteria, which were conducted mostly through online survey method in different study designs and which included a total of 24,889 healthcare professionals were examined. The incidence of PPE-related pressure ulcers was found to be between 30% and 92.8%. Grade I pressure ulcers were the most common (44.1%–82%). The incidence of skin problems except PPE-related pressure ulcers such as itching, redness and dry skin was found to be between 42.8–88.1%. Risk factors that frequently played a role in the development of PPE-related pressure ulcers and other skin problems were longer use of PPE and sweating. PPE-related pressure ulcers and other skin problems were more frequent over the nose (nasal bone/nasal bridge), ears, forehead and cheeks. PPE-related itching, redness and dry skin mostly occurred. Several dressing applications were found to be effective in the prevention of PPE-related pressure ulcers and other skin problems that might develop especially on the facial region.ConclusionPPE-related pressure ulcers and other skin problems were found to be higher among healthcare professionals. Data regarding the sealing of dressing applications against viral transmission in the prevention of PPE-related pressure ulcers and other skin problems are limited. It is estimated that future studies will be performed to prevent device-related pressure ulcers in healthcare workers. It is suggested that there is a need to conduct studies with larger samples where expert researchers make observations for pressure ulcers in order to determine the prevalence and incidence of PPE-related pressure ulcers.     

Marginal ulcers after laparoscopic Roux-en-Y gastric bypass: analysis of the amount of daily and lifetime smoking on postoperative risk

BackgroundA common postoperative complication after laparoscopic Roux-en-Y gastric bypass (LRYGB) is the development of marginal ulcers (MUs) at the gastrojejunal anastomosis. Several risk factors, such as smoking, seem to have an impact on the development of MUs.ObjectiveVery little is known about how much smoking increases the risk. We therefore reviewed our patients regarding their smoking behavior and the development of MUs after LRYGB.SettingPrimary care hospital and a university hospital.MethodsThis study included 249 patients who underwent LRYGB surgery between 2010 and 2015 with at least 2 years of follow-up at a single institution. This retrospective analysis focused on the development of marginal ulcers after LRYGB, the time of appearance, and possible risk factors.ResultsA total of 27 (10.8%) patients in this study developed MUs. The majority of MUs (66.7%) occurred within the first postoperative year. Smoking is an independent and statistically significant predictor of the development of MUs with a 4.6-fold greater risk (P = .003). Light, moderate, and heavy daily smokers have the same rate of MUs (17.4% versus 17.1% versus 17.9%, respectively). Light smokers with <10 cigarettes per day are at significantly increased risk for MUs compared with nonsmokers (17.4 versus 4.2%, respectively; P = .027). Former and current smokers are at comparable risks for MUs (13.3% versus 17.5%, respectively; P = .685).ConclusionThe described incidence of 10.8% shows that marginal ulcers are one of the most important and frequent complications after LRYGB. Smoking at every intensity is associated with an extraordinary risk of MU formation after LRYGB and therefore, smoking cessation before bariatric surgery must be strongly recommended.     

Disability,kinesiophobia, perceived stress,and pain are not associated with trunk muscle strength or aerobic capacity in chronic nonspecific low back pain

ObjectivesTo investigate to which extent disability, psychological and pain-related factors are associated with the outcomes of an isometric trunk muscle strength test and a cardiopulmonary exercise test in persons with chronic nonspecific low back pain (CNSLBP).DesignCross-sectional study.SettingREVAL Rehabilitation Research Center (Hasselt, Belgium).ParticipantsPersons with CNSLBP.Main outcome measuresQuestionnaires concerning disability, patient specific functioning, kinesiophobia, perceived stress, pain intensity, and central sensitization were recorded. Outcomes of an isometric trunk strength test (maximum back and abdominal torque) and cardiopulmonary exercise test (VO₂max) were assessed. Multivariate linear regression models determined factors explaining outcome variance.ResultsData of 101 persons (39 males, mean age: 44.2y (SD = 9.6)) was assessed. Neither disability, nor psychological, nor pain-related factors were associated with the assessments. Variance in back muscle strength (R² = 0.44, F = p < 0.01), abdominal muscle strength (R² = 0.68, F = p < 0.01), and aerobic capacity (R² = 0.76, F = p < 0.01) could only be explained through the included demographics covariates (age, gender, weight).ConclusionThis study highlighted the lack of biopsychosocial factors in explaining variance in outcomes of abdominal and back strength, and aerobic capacity in persons with CNSLBP with characteristics as depicted in the current sample. This information supports the valid interpretation of the outcomes of these assessments.
