Symptoms Of Abdominal Pain Research Articles

Whipple Disease in 2 Southwest Missouri Patients

Abstract Whipple disease (WD) is a rare condition caused by infection with Tropheryma whipplei, a ubiquitous bacterium whose detailed pathogenesis has yet to be elucidated. Its vague defining symptoms of polyarthralgia, weight loss, diarrhea, and abdominal pain do not lend themselves to a rapid diagnosis. The importance of considering WD in a differential diagnosis and recognizing the many manifestations of the condition must not be underestimated. Inadequate or delayed diagnosis can have a significant impact on morbidity and mortality. In this report, we describe 2 cases of classic WD, including representative imaging and histopathology, that were diagnosed almost simultaneously in 2 unrelated adult residents of Southwest Missouri.

Poor Subjective Sleep Quality Predicts Symptoms in Irritable Bowel Syndrome Using the Experience Sampling Method.

Sleep quality may affect symptom experience in irritable bowel syndrome (IBS). Our aim was to investigate the relationship between sleep quality and gastrointestinal (GI) symptoms using actigraphy and the experience sampling method. Patients with IBS were recruited from a tertiary Neurogastroenterology clinic and the community. GI symptoms and mood were recorded on a smartphone application, 10 times per day, over 7 consecutive days. Subjective sleep quality was recorded every morning to reflect the night before. Objective measures of sleep quality were estimated from wrist-worn actigraphy. Cross-lagged structural equation models were built to assess the directionality of sleep-symptom relationships over time. Eighty patients with IBS completed the study (mean age: 37 years [range 20-68], 89% female, 78% community). Approximately 66% had a Pittsburgh Sleep Quality Index score ≥ 8, indicating a clinically significant sleep disturbance. Approximately 82% (95% CI: 72-90) screened positive for a sleep disorder, most commonly insomnia. In cross-lagged analysis, poor subjective sleep quality predicted next-day abdominal pain (0.036 < P < 0.040) and lower GI symptoms (0.030 < P < 0.032), but not vice versa. No significant relationship with GI symptoms was found for any objective sleep measure using actigraphy. Poor subjective sleep quality was associated with higher next-day lower GI symptom levels, but not vice versa. Objective sleep measures did not predict next-day abdominal symptoms, potentially supporting the conclusion that it is the perception of sleep quality that is most influential. This study may be used to guide future research into the effect of sleep interventions on GI symptoms.

Prevalence of vomiting and nausea and associated factors after chronic and acute gluten exposure in celiac disease

BackgroundVomiting and nausea seem to be relatively specific symptoms related to gluten ingestion in treated celiac disease. However, the overall prevalence and associated factors of these symptoms after chronic gluten exposure at celiac disease diagnosis and acute re-exposure during gluten challenge remain obscure.MethodsMedical data on 815 adult celiac disease patients were collected at diagnosis from the medical records and through supplementary interviews. An additional 74 patients underwent a three-day (10 g/day) gluten challenge (wheat, barley, rye or a combination of the three grains) while in remission. Prevalence of vomiting/nausea and associated factors were evaluated in both cohorts. A literature review was conducted to summarize earlier studies.ResultsTwenty-eight (3%) patients presented with vomiting at diagnosis. They were less often screen-detected and suffered from extra-intestinal symptoms, and had more often abdominal pain (71% vs. 49%, p = 0.021), diarrhea (61% vs. 40%, p = 0.031), weight loss (36% vs. 17%, p = 0.019) and childhood symptoms (61% vs. 33%, p = 0.002) than those without vomiting (n = 787). The groups were comparable in other clinical-demographic data and in genetic, serological, and histological findings. Short-term gluten challenge provoked vomiting/nausea in 14/74 (19%) patients. They consumed gluten-free oats less often than those without these symptoms (64% vs. 92%, p = 0.017), whereas the groups did not differ in clinical-demographic features at diagnosis, presence of comorbidities, duration of gluten-free diet, or in other symptoms or grain used ingested during the challenge. According to the literature, prevalence of vomiting/nausea at celiac disease diagnosis has varied 3–46% and during gluten challenge 13–61%.ConclusionsIn chronic gluten exposure at celiac disease diagnosis, vomiting was associated with other gastrointestinal symptoms and onset of symptoms already in childhood, whereas regular consumption of oats may increase the tolerance against vomiting/nausea after acute re-exposure in treated celiac disease.

Gastrointestinal Symptoms in Pediatric Patients with Anxiety Disorders and Their Relationship to Selective Serotonin Reuptake Inhibitor Treatment or Placebo.

Gastrointestinal symptoms are commonly reported as adverse effects of selective serotonin reuptake inhibitors (SSRIs), the first-line pharmacologic treatment for pediatric anxiety disorders; however, the temporal course of these symptoms during treatment, although believed to be transient, has never been prospectively evaluated. Additionally, rates of gastrointestinal symptoms and functional gastrointestinal syndromes in anxious youth are poorly understood. We examined gastrointestinal symptoms in youth with anxiety disorders during a double-blind, placebo-controlled trial of escitalopram (n = 51). Then, in a separate sample of prospectively treated children and adolescents with generalized, social and/or separation anxiety disorders (n = 56), we examined the frequency of gastrointestinal symptoms based on the Questionnaire on Pediatric Gastrointestinal Symptoms (QPGS) and ROME III criteria and the association of these symptoms with clinical and demographic characteristics using logistic regression. The frequency/severity of abdominal pain, diarrhea, bloating constipation or total gastrointestinal symptoms did not differ between patients receiving placebo (n = 25) or escitalopram (n = 26). However, escitalopram-treated youth had transient changes in nausea/vomiting and total upper gastrointestinal symptoms during the first two weeks of treatment. ROME III criteria for functional gastrointestinal syndromes were present in 12/56 patients (21.4%). QPGS-related functional gastrointestinal syndromes and symptoms were unrelated to treatment, treatment type, or clinical or demographic variables. Gastrointestinal symptoms are common in youth with anxiety and SSRIs produce transient-rather than sustained-gastrointestinal symptoms. Assessing gastrointestinal symptoms prior to pharmacotherapy and discussing factors that increase (or decrease) the likelihood of transient SSRI-related symptoms in youth may decrease patient uncertainty related to side effects and decrease medication-related anxiety.

Trends in Gastroparesis Management: A United States Population-based Study From 2010 to 2020.

There is little consensus on the medical management of gastroparesis, a disorder characterized by delayed gastric emptying with symptoms of early satiety, nausea, vomiting, and upper abdominal pain. We utilized population-level data to: (1) describe the prevalence of different pharmacological and nonpharmacological therapies in patients with gastroparesis; and (2) trend the prevalence of these therapies from 2010 to 2020. More than 59 million unique medical records across 26 US-based major health care systems were surveyed using the Explorys platform to identify a cohort of adults with gastroparesis who completed both a gastric emptying study and upper endoscopy or upper gastrointestinal tract imaging. Prevalence of antiemetic, prokinetic, neuromodulator prescriptions, and surgical therapies for gastroparesis were searched within this cohort and trended annually from 2010 to 2020. Antiemetics (72% of patients), prokinetics (47%), and neuromodulators (75% of patients, 44% of patients without a concomitant psychiatric or diabetic peripheral neuropathy diagnosis) were all commonly used in the treatment of patients with gastroparesis. From 2010 to 2020, there was an increase in the prevalence of antiemetic and neuromodulator prescriptions (36.4% to 57.6%, P <0.001 and 47.0% to 66.9%, P <0.001, respectively), whereas the prevalence of prokinetics remained relatively constant (31.8% to 31.6%, P =0.52). Procedural and surgical treatments were used in 5% of gastroparesis patients. Treatments for gastroparesis have changed over the last decade: antiemetic and neuromodulator use has increased whereas prokinetic use has remained constant. This practice pattern may reflect the growing number and availability of antiemetics and neuromodulators and the small number and known side effects of prokinetics.

Clinical information associated with bacterial culture proven Burkholderia pseudomallei among melioiodosis patients in Buriram province

Indirect hemagglutination assay (IHA) is a general rapid diagnosis procedure in melioidosis patients combined with clinical information. The Burkholderia pseudomallei culture technique requires prolonged time before getting culture results. Related factors of bacterial culture proven melioidosis and the appropriate cut-off point for IHA are unfashionable and need to be updated. A cross-sectional study was conducted among melioidosis patients using data reported in the medical records. Univariable analysis was performed by Chi-square test and Student T-test as appropriate. Multivariable logistic regression was finally used to identify the contributing factors to bacterial culture proven cases. The results were shown as adjusted odds ratio (AdjOR) and 95%CI. Validity domains, sensitivity, specificity, predictive values, and likelihood ratios at each cut-off point for IHA were demonstrated. The results revealed that after adjustment for abdominal pain symptoms, diabetes mellitus (DM)(p-value &lt; 0.001) and dyspnea symptoms (p-value = 0.025) were the associated factors of bacterial culture proven cases. The IHA titer &gt; 1: 10240 provided the highest positive and negative predictive values, 30% and 69% respectively. Both positive and negative likelihood ratios of this cut-off point were also accounted for as 0.95 and 1.003, respectively. Health personnel should perform melioidosis diagnosis by the use of clinical information and an appropriate cut-off point for IHA, especially in diabetic patients who have dyspnea.

Synchronous bilateral ovarian torsion followed by recurrent unilateral torsion in a patient undergoing fertility treatment: A case report and literature review

BackgroundOvarian torsion (OT) is a gynaecological emergency and requires prompt recognition and treatment in order to prevent the loss of ovarian function. Patients who are undergoing fertility treatment are at an increased risk of developing OT. ObjectiveThe diagnosis of OT in patients undergoing fertility treatment can be challenging as they often present with abdominal pain and other non-specific symptoms. We highlight the importance of early diagnosis of suspected torsion and performed a literature review on cases of bilateral OT to review its presentation, investigation, and subsequent management.Case report: A 32-year-old nulliparous woman who was undergoing controlled ovarian stimulation presented with lower abdominal pain and was initially managed as ovarian hyperstimulation syndrome (OHSS). Her pain did not subside following conservative management and she proceeded to have a laparoscopy which demonstrated synchronous bilateral ovarian torsion (SBOT), both ovaries were detorted. Eight months later, she was preparing for her frozen embryo transfer (FET) cycle, patient again presented with significant right sided abdominal pain and was found to have a recurrent torsion of the right ovary which was again detorted successfully. ConclusionsClinicians should have a low-threshold to investigate and rule out OT in patients who present with lower abdominal pain, especially in those with additional risk factors for torsion. Patients with confirmed torsion can be successfully managed with detorsion of the ovaries. Further research is needed to determine the best management option for patients with recurrent torsion episodes.

Case Report: Primary small bowel adenocarcinoma with peritoneal metastasis responded well to a CapeOX + bevacizumab regimen

BackgroundSmall bowel adenocarcinoma (SBA) is a rare condition often presenting with various non-specific gastrointestinal symptoms, making its diagnosis challenging. Delayed diagnosis is common, as patients may not receive the correct diagnosis until complications arise, necessitating further investigations. Furthermore, the management of SBA patients poses difficulties due to the scarcity of high-quality evidence.Case presentationIn this report, we present the case of an elderly man with SBA in the ileum who arrived at our emergency room with acute abdominal pain. The diagnosis was not made until the SBA caused a perforation, leading to acute abdominal pain. An emergent exploratory laparotomy revealed a 3 cm × 3 cm perforated tumor in the ileum, along with widespread metastatic nodules on the omentum, ascending colon, descending colon, and rectum. Postoperative pathological evaluation confirmed the diagnosis of SBA with peritoneal metastasis (pT4N2M1, stage IV). Following surgery, the patient received palliative systemic chemotherapy, which included the CapeOX regimen and the anti-VEGF monoclonal antibody bevacizumab. Remarkably, the patient responded well to this therapy, displaying good tolerance, and we observed no signs of disease progression. As of now, the patient is in good health and continuing with regular follow-up.ConclusionThe early diagnosis of small bowel adenocarcinoma remains a challenge. Delayed diagnosis can lead to a poor prognosis, underscoring the importance of considering SBA as a potential diagnosis for patients with unexplained abdominal pain and gastrointestinal symptoms. This case also highlights the efficacy of palliative chemotherapy with the CapeOX regimen combined with bevacizumab in controlling SBA.

Physical Activity for Quiescent and Mildly Active Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis.

Physical activity (PA) may benefit people with inflammatory bowel diseases (IBD) by improving immunological response, musculoskeletal function, and psychological health. We distilled available evidence on the efficacy and safety of PA to improve health-related quality of life (HRQoL) and relieve persistent symptoms of fatigue, joint pain, abdominal pain, stress, anxiety, and depression in individuals with quiescent/mild IBD. We searched for trials in eight databases and trial registries. Trials using PA as an adjunct therapy in the management of adults (≥18 years) with quiescent or mild IBD, published in English between 2011 and 2023 were identified. Summary effect estimates were expressed as standardized mean difference (SMD) or mean difference (MD) with 95% confidence interval (CI) using random-effects model. From the 10,862 citations retrieved, we included seven randomized controlled trials (RCTs) and one non-RCT. There was no evidence of benefit of PA on HRQoL (SMD 0.34, 95%CI -0.08 to 0.77; I2 57%); high heterogeneity was noted among included trials. PA was found to be efficacious in reducing anxiety (SMD -0.35, 95%CI -0.65 to -0.05; I2 0%). There was insufficient evidence to make conclusions regarding changes in fatigue, joint pain, abdominal pain, stress, and depression. All trials deemed physical activity safe. PA contributes to reducing anxiety in quiescent/mild IBD. There is marked heterogeneity in methodology among trials investigating PA in adults with quiescent/mild IBD. This review highlights the need for consistent definitions of PA types and intensities in this field of research.

The Use of Pictograms in the Evaluation of Functional Abdominal Pain Disorders in Children

To evaluate whether the use of pictograms improves symptom evaluation for children with functional abdominal pain disorders (FAPDs). This survey study was conducted in 2 academic centers and included patients aged 8-18years visiting the outpatient clinic for FAPD symptom evaluation. Patients were randomized to fill out the questionnaire without or with accompanying pictograms to assess gastrointestinal symptoms. Afterwards, patients underwent clinical health assessment by the healthcare professional (HCP). Subsequently, the HCP filled out the same questionnaire without pictograms, while blinded to the questionnaire completed by the patient. Primary outcome was the level of agreement between identified symptoms as assessed by patients and HCP. We included 144 children (questionnaire without accompanying pictograms [n=82] and with accompanying pictograms [n=62]). Overall agreements rates were not significantly different (without pictograms median, 70% vs with pictograms median, 70%). Accompanying pictograms did not significantly improve the assessment of abdominal pain symptoms. Accompanying pictograms were beneficial for concordance rates for nausea and vomiting symptoms (without pictograms median, 67% vs with pictograms median, 100%; P=.047). Subgroup analyses for children aged 8-12years of age revealed similar results (concordance on the presence of nausea and vomiting without pictograms median, 67% vs with pictograms median, 100%; P=.015). Subgroup analyses for children ages 12-18years showed no significant differences in concordance rates. Pictograms do not seem to improve the assessment of FAPDs. However, the use of pictograms improves the evaluation of nausea and vomiting, especially for children aged 8-12years. Therefore, HCPs could consider using pictograms in that setting during consultations.

La clasificación 4A para pacientes con insuficiencia tricuspídea

Introduction and objectivesSignificant tricuspid regurgitation (TR) is associated with increased morbidity and mortality. Clinical evaluation of TR patients is challenging. Our aim was to establish a new clinical classification specific for patients with TR, the 4A classification, and evaluate its prognostic performance. MethodsWe included patients with isolated TR that was at least severe and without previous episodes of heart failure (HF) who were assessed in the heart valve clinic. We registered signs and symptoms of asthenia, ankle swelling, abdominal pain or distention and/or anorexia and followed up the patients every 6 months. The 4A classification ranged from A0 (no A) to A3 (3 or 4 As present). We defined a combined endpoint consisting of hospital admission due to right HF or cardiovascular mortality. ResultsWe included 135 patients with significant TR between 2016 and 2021 (69% females, mean age 78±7 years). During a median follow-up of 26 [IQR, 10-41] months, 39% (n=53) patients had the combined endpoint: 34% (n=46) were admitted for HF and 5% (n=7) died. At baseline, 94% of the patients were in NYHA I or II, while 24% were in classes A2 or A3. The presence of A2 or A3 conferred a high incidence of events. The change in 4A class remained an independent marker of HF and cardiovascular mortality (adjusted HR per unit of change of 4A class, 1.95 [1.37-2.77]; P<.001). ConclusionsThis study reports a novel clinical classification specifically for patients with TR that is based on signs and symptoms of right HF and has prognostic value for events.

A retrospective review of α-gal syndrome complicating the management of suspected pancreatic exocrine insufficiency in one gastroenterology clinic in central Virginia

The galactose-α-1,3-galactose (α-gal) mammalian meat allergy, α-gal syndrome, often includes diarrhea, abdominal pain, and other gastrointestinal (GI) symptoms. Pancreatic exocrine insufficiency causes similar symptoms. The pancreatic replacement enzymes, referred to here as pancreatic enzymes, used to treat pancreatic insufficiency are porcine products and contain α-gal. Patients with pancreatic insufficiency who also have α-gal syndrome may be intolerant of mammalian products in their diet and of α-gal in pancreatic enzymes. In this article, we describe 40 patients from one GI clinic in central Virginia with suspected pancreatic insufficiency and increased α-gal immunoglobulin E (IgE) levels. Over 50% of these patients had some clinical improvement when mammalian products were removed from the diet. Most patients could tolerate pancreatic enzymes; 10% could not tolerate them due to suspected allergy symptoms, but none developed anaphylaxis. Understanding that α-gal syndrome can be superimposed on pancreatic exocrine insufficiency and exacerbate symptoms, and that treatment with pancreatic enzymes may increase GI and/or allergy symptoms in this group, will lead to improved medical management of this complex patient population.

Unmasking the Hidden Fetus: Introducing the Circled Delta Sign and Reversed Circled Delta Sign for Accurate Identification on Abdominal Radiography.

BACKGROUND Ionizing radiation poses potential health risk to fetuses, including growth retardation, organ malformations, neurological effects, fetal death, and cancer. Therefore, pregnant women rarely undergo X-ray imaging, unless absolutely necessary. However, they can be inadvertently exposed to X-rays while undergoing an examination without being aware of their pregnancy. Given that the likelihood of a fetus appearing on an abdominal radiograph is low, physicians can be unfamiliar with the appearance of a fetus on such images. If a fetus incidentally appears on an abdominal radiograph, the clinician can encounter difficulties in identifying the fetus, potentially leading to unexpected harm during subsequent imaging procedures. CASE REPORT A 41-year-old woman presented with symptoms of postprandial abdominal pain, abdominal fullness, and urinary frequency. Abdominal radiography revealed a large mass with calcifications in the pelvis and lower abdomen, raising suspicion of a large pelvic tumor, such as a teratoma. However, subsequent ultrasound unexpectedly revealed that the woman was actually 6 months pregnant. The presumed tumor was an enlarged uterus, and the presumed calcifications were the fetus's bones. Before X-ray, the woman had denied being pregnant, mistakenly attributing her condition to excess weight and irregular menstrual cycles. Fortunately, the use of ultrasound instead of computed tomography prevented radiation exposure to the fetus, and the baby was delivered in a healthy state at full term. CONCLUSIONS To avoid unintended harm to fetuses, clinicians should consider the possibility of pregnancy when evaluating a pelvic mass in women of childbearing age. To aid clinicians in accurately identifying fetuses on abdominal radiography and thereby reduce the likelihood of misdiagnosis, we propose the "circled delta sign" and the "reversed circled delta sign".

Ectopic decidual reaction – A diagnostic dilemma

The occurrence of decidualization outside the endometrium, is called as ectopic decidual reaction. It can involve any abdominal organs, such as ovary, fallopian tube, cervix, uterine surface, omentum, etc. and present as grey white nodules. These nodules grossly mimic metastatic disease and granulomas, causing a diagnostic dilemma. Decidual reaction is a benign condition and can regress spontaneously in the postpartum period. Thus, it is important to accurately diagnose these lesions for optimal treatment. Histologic examination followed by immunohistochemistry can be performed on the biopsies sampled during cesarean sections, tubal ligation, appendectomy, etc. to obtain a correct diagnosis. Peritoneal location of ectopic decidua is less frequent and can be an incidental finding. Few patients may present with the symptoms of abdominal pain, hemorrhage or irritable bowel syndrome. We thereby, report a case of peritoneal ectopic decidual reaction and discuss its histopathological features, immunohistochemistry and the differential diagnosis.

Ectopic insulinoma: a systematic review.

Knowledge of ectopic insulinomas comes from single cases. We performed a systematic review through PubMed, Web of Science, Embase, eLibrary and ScienceDirect of all cases reported in the last four decades. We also describe one unreported patient. From 28 patients with ectopic insulinoma, 78.6% were female and mean age was 55.7 ± 19.2 years. Hypoglycaemia was the first symptom in 85.7% while 14.3% complained of abdominal pain or genital symptoms. Median tumour diameter was 27.5 [15-52.5] mm and it was localised by CT (73.1%), MRI (88.9%), [68Ga]Ga-DOTA-exedin-4 PET/CT (100%), 68Ga-labelled-DOTA-conjugated somatostatin analogue PET/TC (100%), somatostatin receptor scintigraphy (40%) and endoscopic ultrasound (50%). Ectopic insulinomas were located at duodenum (n = 3), jejunum (n = 2), and one respectively at stomach, liver, appendix, rectum, mesentery, ligament of Treitz, gastrosplenic ligament, hepatoduodenal ligament and splenic hilum. Seven insulinomas were affecting the female reproductive organs: ovary (n = 5), cervix (n = 2) and remaining tumours were at retroperitoneum (n = 3), kidney (n = 2), spleen (n = 1) and pelvis (n = 1). 89.3% underwent surgery (66.7% surgery vs. 33.3% laparoscopy) and 16% underwent an ineffective pancreatectomy. 85.7% had localized disease at diagnosis and 14.3% developed distant metastasis. Median follow-up time was 14.5 [4.5-35.5] months and mortality was reported in 28.6% with median time until death of 60 [5-144] months. In conclusion, ectopic insulinomas are presented as hypoglycaemia with female preponderance. Functional imaging [68Ga]Ga-DOTA-exedin-4 PET/CT and 68Ga-labelled-DOTA-conjugated somatostatin analogue PET/TC have very high sensitivity. Clinicians should be alert to the possibility of extra-pancreatic insulinomas when classic diagnostic tests and intraoperative pancreas exploration failed to locate the tumour.

Patient-reported outcomes, weight loss, and remission of type 2 diabetes 3 years after gastric bypass and sleeve gastrectomy (Oseberg); a single-centre, randomised controlled trial

Little is known about the comparative effects of various bariatric procedures on patient-reported outcomes. We aimed to compare 3-year effects of gastric bypass and sleeve gastrectomy on patient-reported outcome measures in patients with obesity and type 2 diabetes. The Oseberg trial was a single-centre, parallel-group, randomised trial at Vestfold Hospital Trust, a public tertiary obesity centre in Tønsberg, Norway. Eligible patients were aged 18 years or older with previously verified BMI 35·0 kg/m2 or greater. Diabetes was diagnosed if glycated haemoglobin was at least 6·5% (48 mmol/mol) or by their use of anti-diabetic medications with glycated haemoglobin at least 6·1% (43 mmol/mol). Eligible patients were randomly assigned (1:1) to gastric bypass or sleeve gastrectomy. All patients received identical preoperative and postoperative treatment. Randomisation was done with a computerised random number generator and a block size of ten. Study personnel, patients, and the primary outcome assessor were blinded to allocations for 1 year. The prespecified secondary outcomes reported here were 3-year changes in several clinically important patient-reported outcomes, weight loss, and diabetes remission. Analyses were done in the intention to treat population. This trial is ongoing, closed to recruitment and is registered with ClinicalTrials.gov, NCT01778738. Between Oct 15, 2012 and Sept 1, 2017, 319 consecutive patients with type 2 diabetes scheduled for bariatric surgery were assessed for eligibility. 101 patients were not eligible (29 did not have type 2 diabetes according to inclusion criteria and 72 other exclusion criteria) and 93 declined to participate. 109 patients were enrolled and randomly assigned to sleeve gastrectomy (n=55) or gastric bypass (n=54). 72 (66%) of 109 patients were female and 37 (34%) were male. 104 (95%) of patients were White. 16 patients were lost to follow up and 93 (85%) patients completed the 3-year follow-up. Three additional patients were contacted by phone for registration of comorbidities Compared with sleeve gastrectomy, gastric bypass was associated with a greater improvement in weight-related quality of life (between group difference 9·4, 95% CI 3·3 to 15·5), less reflux symptoms (0·54, 0·17 to -0·90), greater total bodyweight loss (8% difference, 25% vs 17%), and a higher probability of diabetes remission (67% vs 33%, risk ratio 2·00; 95% CI 1·27 to 3·14). Five patients reported postprandial hypoglycaemia in the third year after gastric bypass versus none after sleeve-gastrectomy (p=0·059). Symptoms of abdominal pain, indigestion, diarrhoea, dumping syndrome, depression, binge eating, and appetitive drive did not differ between groups. At 3 years, gastric bypass was superior to sleeve gastrectomy in patients with type 2 diabetes and obesity regarding weight related quality of life, reflux symptoms, weight loss, and remission of diabetes, while symptoms of abdominal pain, indigestion, diarrhoea, dumping, depression and binge eating did not differ between groups. This new patient-reported knowledge can be used in the shared decision-making process to inform patients about similarities and differences between expected outcomes after the two surgical procedures.

IDENTIFICATION OF BENZOIC ACID BY GC AND MASS SPECTROMETRY

Benzoic acid is an aromatic carboxylic acid naturally present in plant and animal tissues which can also be produced by microorganisms. Benzoic acid and a wide range of derivatives and related benzenoid compounds, such as salts, alkyl esters, parabens, benzyl alcohol, benzaldehyde and benzoyl peroxide, are commonly used as antibacterial and antifungal preservatives and as flavouring agents in food, cosmetic, hygiene, and pharmaceutical products. Benzoic acid (BA) is a commonly used antimicrobial preservative in food and beverages, especially in carbonated beverages, as it presents in its strongest antibacterial activity at pH 2.5–4.0. BA has inhibitory effects on the proliferation of bacteria and yeasts, a major cause of food spoilage. Although the addition of BA can extend the shelf life of drinks and prevent nutritional losses.Excessive intake of BA may cause diarrhea, abdominal pain, and other symptoms and even interfere with the intermediate metabolic processes of the body.

A rare outcome of liposuction complicated by the development of peritonitis following perforation of the small intestine: a case report

There are a growing number of demands for liposuction each year and it is one of the most performed procedures in plastic surgery for aesthetic purposes. Bowel perforation and peritonitis are rare, but life-threatening complications following liposuction. However, there is a lack of awareness of these ill-fated outcomes which are underestimated and under-reported in the literature. We present the case of a 63-year-old male admitted to emergency department (ED) with the symptoms of abdominal pain and distension with anorexia and nausea. The patient stated that he had not been feeling well since the liposuction procedure which he received 6 days prior. During the physical examination, there was mild abdominal distension with tenderness and some guarding in all 4 quadrants. A computed tomography (CT) scan showed pneumoperitoneum. The patient underwent an exploratory laparotomy where multiple small bowel perforations were repaired and a part of the small bowel was resected. The patient eventually recovered well and was discharged on post-op day 12. Bowel perforation which can lead to peritonitis following liposuction is rare, but the risk increases in patients with a previous history of abdominal surgery such as hernia repair, as in this patient. Increased awareness of possible life-threatening complications and close follow-up in patients with risk factors are essential to prevent undesirable outcomes and promptly treat the patient.

A Randomized Parallel-group Study of Digital Gut-directed Hypnotherapy vs Muscle Relaxation for Irritable Bowel Syndrome

Gut-directed hypnotherapy (GDH) is effective for treating irritable bowel syndrome (IBS), but access limits its widespread use. We report the first randomized controlled trial comparing the safety and efficacy of a self-administered, digital GDH treatment program with that of digital muscle relaxation (MR) in adults with IBS. After a 4-week run-in period, patients were randomized to 12 weeks of treatment with digital GDH (Regulora), or digital MR accessed via a mobile app on a smartphone or tablet. The primary endpoint was abdominal pain response, defined as ≥30% reduction from baseline in average daily abdominal pain intensity in the 4 weeks following treatment. Key secondary outcomes included mean change from baseline in abdominal pain, stool consistency, and stool frequency. Of 378 randomized patients, 362 were treated and included in the efficacy analysis. A similar proportion of the GDH (30.4%) and MR (27.1%) groups met the primary endpoint, with no significant difference between the groups (P= .5352). Significantly more patients treated with GDH than MR were abdominal pain responders during the last 4 weeks of treatment (30.9% vs 21.5%; P= .0232) and over the entire treatment period (29.3% vs 18.8%; P= .0254). Improvements in abdominal pain, stool consistency, and stool frequency were consistent across IBS subtypes. No patients experienced serious adverse events or adverse events leading to study discontinuation. Treatment with a digital GDH program led to an improvement in abdominal pain and stool symptoms in patients with IBS, supporting a role for this intervention as part of integrated care for IBS. gov identifier NCT04133519.

Code Pseudo Stroke - A Case of Hypokalaemic Periodic Paralysis Mimicking Stroke.

Hypokalaemic periodic paralysis is an acute flaccid paralysis secondary to hypokalaemia, triggered by hyperthyroidism, environmental elements such as a high carbohydrate intake or rest after intense exercise, and an underlying genetic component with mutations in the muscle ion channels.The pursuit of code stroke protocol in the in-patient setting must bear in mind reversible but potentially fatal and disabling alternative diagnoses such as stroke mimics including hypokalaemic periodic paralysis.Stroke mimics defined as acute onset neurological deficits that are not related to vascular cause are a true challenge, multiple scales have been created to distinguish them from an actual stroke, such as the Recognition of Stroke in the Emergency Room (ROSIER) scale.
