Hiatal hernia (HH) is associated with gastroesophageal reflux disease (GERD); the effect of HH size on GERD is not well defined. To evaluate the relationship between HH size as measured by high-resolution esophageal manometry (HREM) and reflux parameters on esophageal pH-impedance testing (multichannel intraluminal impedance-pH [MII-pH]) to define HH sizes associated with GERD. HREM and MII-pH studies were reviewed. The relationship of HH size to other parameters was analyzed with multivariable logistic regression. Correlation coefficients were determined using Spearman and Pearson's tests. A total of 897 patients underwent both HREM and MII-pH. There were 529 (58.9%) patients with HH size <1 cm, 203 (22.6%) with HH 1.0–1.9 cm, and 165 (18.4%) with HH ≥2 cm. Larger HH size was associated with lower esophageal sphincter (LES) basal and residual pressures (r  = −0.43 and r  = −0.48, p  < 0.01), higher acid exposure time (AET) (r  = 0.17, p  < 0.01), number of acidic refluxes (r  = 0.16, p  < 0.05), and number of reflux episodes detected by impedance (total r  = 0.22, p  < 0.01). HH ≥ 2 cm compared with smaller size HH was associated with higher proximal AET%, acidic refluxes, and reflux episodes detected by impedance (p  < 0.05). Increasing HH size was associated with older age, higher AET, and number of reflux episodes. HH ≥2 cm was associated with multiple worsened GERD parameters. Low LES pressure was weakly associated with an increase in the number of reflux episodes. Larger HHs, particularly >2 cm, are associated with more severe GERD parameters. [ABSTRACT FROM AUTHOR]

Hyperthyroidism is associated with increased risk of cardiovascular conditions. We report a case of a 50-year-old woman with no prior cardiac history who presented to the emergency department with shortness of breath, chest pain, lower extremity swelling, and generalized fatigue. She was found to have Graves’ Disease (GD) and extensive coronary artery disease (CAD), suggesting the possibility of increased risk of de novo CAD in patients with GD in the absence of other risk factors.

Acquired adult-onset zinc deficiency is occasionally reported in patients with malnutrition states, such as alcoholism, or malabsorptive states, such as post-bariatric surgery. The defining symptoms of hypozincemia include a classic triad of necrolytic dermatitis, diffuse alopecia, and diarrhea. We report a case of zinc deficiency in a 39-year-old man with history of gastric bypass surgery and alcoholism. For this patient, severe hypozincemia confirmed acrodermatitis, and zinc supplementation was met with gradual improvement. [ABSTRACT FROM AUTHOR]

Background: Arsenic (As), one of the most significant hazards in the environment affecting millions of people around the world is associated with several diseases including cancers, Diabetes Mellitus (DM) and Hypertension (Htn). Drinking water contaminated with inorganic arsenic (iAs) is the primary route of exposure. This study was conducted to determine the difference in the prevalence of DM and Htn in areas with different levels of water contamination of As. Materials and Methods: In this analytic ecologic study, after measurement of As level in drinking water in all urban regions of Qazvin Province (Islamic Republic of Iran), two cities with As level of 20-30 µ/L and two with the As level <5 µg/L were selected as exposed and unexposed groups, respectively. Measuring the prevalence of above-mentioned diseases in the 30-60 year-old population of the said regions as total sampling, the results were statistically analyzed and compared. Results: The mean prevalence of Htn in exposed and unexposed areas were 7.09% and 3.73%, respectively and for DM were 4.53% and 1.99% in the said groups, respectively. There was a positive correlation between As level and Htn (P < 0.001) and between As level and DM (P < 0.001). Conclusion: High level of As in drinking water, even in the range of 20-30 µg/L has a relationship with increased prevalence of DM and Htn. [ABSTRACT FROM AUTHOR]

Background: Patients with gastroparesis often consume only small meals due to early satiety. Aims: (1) Describe meal eating characteristics of patients with gastroparesis; (2) Relate meal eating characteristics to symptoms, gastric emptying (GE), and body weight. Methods: Patients with gastroparesis filled out questionnaires including Patient Assessment of Upper GI Symptoms (PAGI-SYM), and questionnaire about meal habits and body weight. Patients underwent gastric emptying scintigraphy. Results: Of 192 gastroparesis patients, 93% endorsed early satiety (ES) with severity of 3.7 ± 1.5 (scored from 0–5) and 93% endorsed postprandial fullness (PPF) with severity of 3.9 ± 1.3. Time spent consuming meals averaged 13.6 ± 17.7 min. Main reasons patients stopped eating were fullness (61%), nausea (48%), and abdominal pain (31%). Time spent eating correlated inversely with severity of nausea (r = −0.18, p < 0.05), stomach fullness (r = −0.21, p < 0.01), PPF (r = −0.23, p < 0.01), loss of appetite (r = −0.34, p < 0.01). Postprandial fullness lasted for 316 ± 344 min. Duration of PPF correlated with nausea (r = 0.30, p < 0.01), retching (r = 0.29, p < 0.01), vomiting (r = 0.28, p < 0.01), stomach fullness (r = 0.33, p < 0.01), loss of appetite (r = 0.35, p < 0.01), and constipation (r = 0.27, p < 0.01). Underweight patients had increased inability to finish a normal size meal (p < 0.01), loss of appetite (p < 0.01), and lower abdominal pain/discomfort (p < 0.05). Patients had lost 3.06 ± 10.60 kgs from their baseline weight. Weight loss correlated with nausea (r = 0.26, p < 0.01), ES (r = 0.30, p < 0.01), loss of appetite (r = 0.28, p < 0.01). Conclusions: Early satiety and postprandial fullness were common with high severity. The main reasons for meal cessation were early satiety, nausea, and abdominal pain. Body weight and change in body weight were associated with symptoms of gastroparesis. [ABSTRACT FROM AUTHOR]

Background: Peripheral neuropathy (PN) is present in diabetic gastroparesis but is not described in idiopathic gastroparesis.Aims: (1) Determine prevalence of PN in idiopathic gastroparesis; (2) assess if patients with symptoms of gastroparesis and PN differ in gastric emptying and symptoms, both gastrointestinal and psychosocial, from patients without PN (nPN); (3) compare this relationship to that in other etiological groups.Methods: 250 patients with symptoms of gastroparesis underwent gastric emptying scintigraphy and answered questionnaires including severity of gastroparesis symptoms using the Gastroparesis Cardinal Symptom Index (GCSI) and presence of peripheral neuropathy using the Neuropathy Total Symptom Score-6 (NTSS-6).Results: PN, defined by NTSS-6 > 6, was present in 70/250 (28%) patients: 22/148 (15%) idiopathic, 33/61 (54%) diabetic, and 11/32 (34%) postsurgical (p < 0.01). Among 148 patients with symptoms of idiopathic gastroparesis, defined as non-diabetic, non-postsurgical, and not caused by a known disorder such as Parkinson's or connective tissue disease, symptoms of gastroparesis were more severe in PN than nPN: bloating (4.05 ± 1.17 vs. 2.99 ± 1.61, p < 0.01), abdominal distension (3.86 ± 1.49 vs. 2.45 ± 1.68, p < 0.01), and upper abdominal pain (3.64 ± 1.22 vs. 2.71 ± 1.78, p = 0.03). Ninety-nine idiopathic patients underwent gastric emptying scintigraphy: 7/43 (16%) patients with delayed gastric emptying and 9/56 (16%) patients with normal gastric emptying had PN. Among patients with idiopathic gastroparesis, abdominal distension (4.43 ± 0.53 vs. 2.89 ± 1.68, p = 0.01) was more severe in PN than nPN. The association of PN and worse gastrointestinal symptoms was not as apparent in patients with symptoms of diabetic or postsurgical gastroparesis.Conclusions: PN was present in 70/250 (28%) of patients with symptoms of gastroparesis and was present to a lesser extent in idiopathic than diabetic gastroparesis. The presence of PN in IG was associated with more severe gastroparetic symptoms than in nPN. Screening for PN may help identify a gastroparesis cohort with peripheral neuropathy who are more symptomatic. [ABSTRACT FROM AUTHOR]

Background: Gastric emptying scintigraphy (GES) reports percent retention at 1, 2, and 4 h. Time to empty half the meal (T½) could simplify GE reporting. Aims: To compare the performance of GES T½ to 1‐, 2‐, and 4‐h retention. Methods: GES studies were reviewed; results determined according to retention at 1, 2, and 4 h. T½ was determined using 3 methods: (1) GES curve fitting using 0, 0.5, 1, 2, 3, and 4 h data; (2) linear interpolation using 0, 0.5, 1, 2, 3, and 4 h data; and (3) linear interpolation using only 0, 1, 2, and 4 h data. Results: Of 495 patients, 265 had normal GE, 4 rapid GE (<30% retention at 1 h), and 226 delayed GE: 17 delayed only at 2 h (>60% ret); 94 delayed only at 4 h (>10% ret); and 115 delayed at both 2 h and 4 h. Strong correlations were seen between each T½ method and 1, 2, 3, and 4 h %‐empty values: curve‐fit T½ (r = −0.851, −0.942, −0.864, −0.744), linear T½ using all imaging times (r = −0.848, −0.972, −0.878, −0.763), and linear T½ using standard imaging times (r = −0.853, −0.974, −0.868, −0.760). The 132 min cutoff for delayed GE captures 99.1% to 100% of delayed GE at both 2 h and 4 h, 76.5% to 94.1% delayed at 2 h only, but only 36.7% to 39.4% delayed at 4 h only; 3.5 to 11.3% of patients with normal GE miscategorized as delayed. Conclusions: GES T½ correlates more strongly with retention at 2 h than at 4 h. T½ alone may misclassify patients, particularly those with late‐phase (4 h only) delays, reducing its utility for diagnosing gastroparesis. [ABSTRACT FROM AUTHOR]

Background: Symptoms of gastroparesis (Gp) can fluctuate at different times of the day. Our aims are (1) To characterize Gp symptom variability throughout the day and in relation to meals and (2) to compare the daily symptom variability in subtypes of Gp—diabetic gastroparesis (DGp) and idiopathic gastroparesis (IGp). Methods: Patients with Gp filled Patient Assessment of Gastrointestinal Symptoms (PAGI‐SYM) and completed a modified GCSI‐DD seven times a day (GCSI‐Throughout the Day [GCSI‐TTD]; before and after meals, and before going to bed) over a 2‐week period. Key Results: A total of 44 patients participated (86% females), including 29 (66%) with IGp, 13 (30%) with DGp, and 2 (4%) with postsurgical Gp. Using the GCSI‐TTD, patients with Gp reported significant postprandial worsening of overall symptom severity, as well as severities of nausea, early satiety, stomach fullness, and abdominal pain. Patients also had progressive worsening of the overall symptom severity, early satiety, stomach fullness, and abdominal pain during the day; however, nausea severity did not differ during the day. Number of vomiting and retching episodes did not show significant variations postprandially or during the day. Patients with IGp had greater symptom severity throughout the day and greater postprandial increase in symptoms compared to patients with DGp. Conclusions and Inferences: Patients with Gp experience postprandial worsening of overall symptom severity, as well as severities of nausea, early satiety, stomach fullness, and abdominal pain. These symptoms also progressively worsen during the day, except for the severity of nausea which persists throughout the day. Understanding the symptom variability in patients with Gp throughout the day and postprandially may be useful in treatment of patients with Gp. [ABSTRACT FROM AUTHOR]

While bacteremia due to Serratia marcescens is not uncommon, it rarely causes infective endocarditis. We report an isolated case of a 53-year-old male with history of intravenous drug abuse who presented with multiple acute pain symptoms and was found to have S. marcescens bacteremia with septic emboli in his spleen, brain, and testes, secondary to a large aortic vegetation, as well as aortic infective endocarditis with severe aortic regurgitation requiring aortic valve replacement. His course of disease was further complicated by epidural and psoas abscesses and a necrotic testicle requiring orchiectomy due to his ongoing intravenous drug abuse. This case is an atypical presentation of S. marcescens infection, as he had no overt signs of infection such as fever or significant leukocytosis that are typical of bacteremia, and it also highlights the severity and complicated nature of S. marcescens-infective endocarditis.

Background: Dyspeptic symptoms are not well correlated with gastric emptying (GE) results. Aims: To determine (a) prevalence of delayed SB transit (SBT) in patients undergoing GE scintigraphy for symptoms of gastroparesis; (b) symptoms associated with delayed SBT. Methods: Patients with symptoms of gastroparesis underwent combined GE and SBT scintigraphy (GES/SBTS). Patients ingested a mixed solid (S)‐liquid (L) meal with egg whites labeled with 500 µCi Tc‐99 m sulfur colloid and water with 125 µCi In‐111 DTPA. Retained S and L gastric activity and percent of L In‐111 activity in terminal ileum (TI) and/or cecum/colon at 6 h were determined. Patient Assessment of Gastrointestinal Symptoms (PAGI‐SYM) assessed symptoms from 0 (none) to 5 (very severe). Key Results: Of 363 patients, 174 (47.9%) had delayed S GE, 141 (38.8%) delayed L GE, and 70 (19.3%) delayed SBT. Delayed SBT was seen in 24 (6.6%) with normal S GE and 46 (12.7%) with delayed S GE. Patients with isolated delayed SBT had highest symptom scores for postprandial fullness (3.5), stomach fullness (3.4), nausea (3.2), bloating (3.2), compared to isolated delayed S GE who had highest symptom scores for postprandial fullness (3.7), nausea (3.6), stomach fullness (3.4), and early satiety (3.3). Conclusions & Inferences: Delayed SBT occurred in 19.3% of dyspeptic patients using GES/SBTS. While postprandial and stomach fullness were common to both delayed S GE and delayed SBT, early satiety was associated with delayed S GE whereas bloating was associated with delayed SBT. Thus, SBTS can augment GES to help explain some symptoms associated with dyspepsia and suspected gastroparesis. [ABSTRACT FROM AUTHOR]

Patients with chronic constipation who do not respond to initial treatments often need further evaluation for dyssynergic defecation (DD) and slow transit constipation (STC). The aims of this study are to characterize the prevalence of DD and STC in patients referred to a motility center with chronic constipation and correlate diagnoses of DD and STC to patient demographics, medical history, and symptoms. High-resolution ARM (HR-ARM), balloon expulsion testing (BET) and whole gut transit scintigraphy (WGTS) of consecutive patients with chronic constipation were reviewed. Patients completed questionnaires describing their medical history and symptoms at the time of testing. A total of 230 patients completed HR-ARM, BET, and WGTS. Fifty (22%) patients had DD, and 127 (55%) patients had STC. Thirty patients (13%) had both DD and STC. There were no symptoms that were suggestive of STC vs. DD; however, patients with STC and DD reported more severe constipation than patients with normal transit and anorectal function. Patients with chronic constipation often need evaluation for both DD and STC to better understand their pathophysiology of symptoms and help direct treatment. [ABSTRACT FROM AUTHOR]
