Nocturnal heartburn and related sleep disturbances are common among patients with gastroesophageal reflux disease (GERD). This study evaluated the efficacy of dexlansoprazole MR 30 mg in relieving nocturnal heartburn and GERD-related sleep disturbances, improving work productivity, and decreasing nocturnal symptom severity in patients with symptomatic GERD. Patients (N=305) with frequent, moderate-to-very severe nocturnal heartburn and associated sleep disturbances were randomized 1:1 in a double-blind fashion to receive dexlansoprazole MR or placebo once daily for 4 weeks. The primary end point was the percentage of nights without heartburn. Secondary end points were the percentage of patients with relief of nocturnal heartburn and of GERD-related sleep disturbances over the last 7 days of treatment. At baseline and week 4/final visit, patients completed questionnaires that assessed sleep quality, work productivity, and the severity and impact of nocturnal GERD symptoms. Dexlansoprazole MR 30 mg (n=152) was superior to placebo (n=153) in median percentage of nights without heartburn (73.1 vs. 35.7%, respectively; P<0.001). Dexlansoprazole MR was significantly better than placebo in percentage of patients with relief of nocturnal heartburn and GERD-related sleep disturbances (47.5 vs. 19.6%, 69.7 vs. 47.9%, respectively; P<0.001), and led to significantly greater improvements in sleep quality and work productivity and decreased nocturnal symptom severity. Adverse events were similar across treatment groups. In patients with symptomatic GERD, dexlansoprazole MR 30 mg is significantly more efficacious than placebo in providing relief from nocturnal heartburn, in reducing GERD-related sleep disturbances and the consequent impairments in work productivity, and in improving sleep quality/quality of life.

Chronic gastroesophageal reflux disease (GERD) is a risk factor for Barrett's esophagus (BE), the most important surrogate marker for the development of esophageal adenocarcinoma (EAC). The need to document the presence of intestinal metaplasia in esophageal biopsies from a columnar lined esophagus (CLE) to diagnose BE is debated. The objective of this study was to prospectively evaluate the prevalence and risk factors of CLE in a large cohort of GERD patients undergoing upper endoscopy. Consecutive patients presenting to the endoscopy unit at a tertiary referral center for their index upper endoscopy for evaluation of GERD symptoms were enrolled in this prospective cohort study. Patients were asked to complete a validated GERD questionnaire that documents the onset of GERD symptoms (heartburn and acid regurgitation) and grades the frequency and severity of symptoms experienced over the past year. Demographic information, body mass index, and use of aspirin/nonsteroidal antiinflammatory drugs were recorded. Endoscopic details including length of CLE, presence and size of hiatal hernia were noted. Patients with CLE (cases) were compared with those without CLE (controls) using Fischer's exact test and t-test. All factors that were statistically significant (P<0.05) were then entered into stepwise logistic regression to evaluate for independent predictors of CLE. A total of 1058 patients with GERD symptoms were prospectively enrolled. On index endoscopy, the prevalence of CLE was 23.3%, whereas of CLE with documented intestinal metaplasia was 14.1%. On univariate analysis, male gender, Caucasian race, heartburn duration of >5 years, presence and size of hiatal hernia were significantly associated with the presence of CLE compared with controls (P<0.05). On multivariate analysis, heartburn duration >5 years (odds ratio (OR): 1.50, 95% confidence interval (CI): 1.07-2.09, P=0.01), Caucasian race (OR: 2.40, 95% CI: 1.42-4.03, P=0.001), and hiatal hernia (OR: 2.07, 95% CI

Gastroesophageal reflux disease (GERD) causes a wide range of symptoms. Some patients present with typical symptoms such as heartburn and regurgitation and others with atypical symptoms such as chest pain. The mechanism responsible for the varying clinical presentation of GERD is still not fully elucidated. The aim of this study was to prospectively evaluate differences in central and local intraesophageal factors between patients with typical GERD symptoms and those with noncardiac chest pain (NCCP). Patients presenting with typical and atypical symptoms suspicious of GERD underwent upper endoscopy and 24-hour pH monitoring with four sensors, each positioned at a different esophageal level. All patients completed GERD symptom, Hospital Anxiety and Depression Scale, and Symptom Stress Rating questionnaires. From January 2006 to December 2009, 50 patients were recruited, 29 with typical symptoms, and 21 with NCCP. Patients with proven GERD and NCCP had higher proximal extension of acid during reflux episodes than patients with typical symptoms. They were found to be older, had a shorter history of symptom onset, worse anxiety scores, and more endoscopic findings compatible with gastritis. Proximal extension of acid during the reflux episodes in patients with GERD presenting with NCCP may play a role in symptom generation. © 2012 Copyright the Authors.

Endotherapy and surgery for GERD.

PubMed

Triadafilopoulos, George

2007-07-01

Today, there are several modalities to treat gastroesophageal reflux disease (GERD) (medications, endoscopic therapies, surgery) and such therapies can be used either singly, or in tandem, or in combination with the others, aiming at "normalization" of the patient's GERD-related quality of life and, if possible, esophageal acid exposure. Several intermediate end points or clinically significant outcomes have not been reached by some therapeutic modalities and no single modality is or can be perfect. Statistically significant improvements in these intermediate end points have been shown in "some" but not all studies. Although healing of esophagitis can be accomplished with either medical or surgical therapy, there is inadequate data with endotherapies, because most patients treated with endotherapies have had prior trials of proton pump inhibitors (PPIs) and hence healed their esophagitis. Effective prevention of complications, such as esophageal adenocarcinoma, remains challenging for all modalities. Patients who have not normalized their GERD-related quality of life with once or twice daily PPI therapy should undergo functional esophageal evaluation with pH testing and esophageal motility study and they should be evaluated by both an endoscopist and a surgeon. The decision on how to proceed should be made on the basis of the criteria for endotherapy and surgery, availability of local endoscopic and surgical expertise and patients' preference. Such multimodality therapy model is in many ways similar to the long-term management of coronary artery disease where pharmacotherapy, angioplasty, and bypass surgery are frequently used in tandem or in combination. Multimodality therapy aiming at normalization of GERD-related quality of life is an option today, and should be available to all patients in need of therapy. The target population for GERD endotherapy currently consists of PPI-dependent GERD patients, who have a small (<2-cm-long) or no sliding hiatal hernia, and

Emerging therapeutic options in GERD.

Gastroesophageal reflux disease (GERD) is a prevalent problem resulting in a high level of healthcare consultation and expenditure in the Western World. Although standard medical therapy (in the form of proton pump inhibitor drugs) is effective in the majority of cases, there remains a significant proportion who are refractory to treatment. In addition, surgical therapy (in the form of laparoscopic fundoplication) is not always effective, and in some can be associated with significant side-effects, particularly gas-bloat, flatulence and dysphagia. As such there remains an unmet need in GERD to develop new therapies for refractory cases, and to develop alternatives to fundoplication with fewer side-effects. This article discusses the current state of pharmacological and non-pharmacological emerging therapies for GERD. Copyright © 2013 Elsevier Ltd. All rights reserved.

Mucosal Impedance: a New Approach to Diagnosing Gastroesophageal Reflux Disease and Eosinophilic Esophagitis.

PubMed

Barrett, Caroline; Choksi, Yash; Vaezi, Michael F

2018-06-09

In this review, we discuss current diagnostic testing modalities for both gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE) and then introduce mucosal impedance (MI), a novel technology that measures epithelial integrity in real time during endoscopy. We describe the advantages and disadvantages of MI as compared with traditional diagnostic testing. We review studies that demonstrate that GERD and EoE have distinct MI patterns, and that physicians can accurately diagnose and distinguish the two during endoscopy with minimal time added to the procedure. We also review studies showing that MI has the capability to assess treatment response in both GERD and EoE and that it can be used to diagnose GERD in patients with extraesophageal reflux symptoms. Mucosal impedance testing is a major advancement in the diagnosis of GERD and EoE. Future studies are planned to assess whether MI can be used as a treatment endpoint in EoE and whether it can be used to predict response to anti-reflux surgery.

There are various identifiable diseases or conditions that can be associated with an apparent life-threatening event (ALTE) in infancy. The present study was carried out to investigate the etiology of ALTE based on the discharge diagnoses. A protocol for the complete work-up used to examine the cause of ALTE was designed, and was carried out for 69 infants with ALTE. Gastroesophageal reflux disease (GERD) was demonstrated in 38 cases, and chronic gastric volvulus (CGV) was diagnosed in 21 (associated with GERD in 13 infants). Four cases of pertussis and two cases each of sepsis, laryngomalacia, respiratory immaturity, and premature ventricular contractions were found. Others cases presented with pneumonia, meningitis, intussuception, food allergy, epilepsy, and adenoid vegetations. In 12 of the 69 infants with ALTE, no abnormalities were found in any of the studies performed, including two patients with breath-holding spells. In 17 cases, two or more possibly contributing findings were diagnosed. It is important to recognize that gastroesophageal impairments such as GERD or CGV could be responsible for many incidences of ALTE in infancy. The authors recommend a trial be established to investigate the causes of ALTE, including gastroesophageal evaluations in all infants with ALTE.

Comparison of the Carlsson-Dent and GERD-Q questionnaires for gastroesophageal reflux disease symptom detection in a general population.

Gastroesophageal reflux disease (GERD) is an extremely common pathology in the general population and one of the main reasons for consultation in gastroenterology. There are different instruments for detecting its symptoms, but few studies comparing one tool with another have been conducted in Mexico. To compare the effectiveness of the Carlsson-Dent questionnaire (CDQ) and the GERD-Q questionnaire (GQQ) in detecting GERD symptoms in a general population. A prospective, descriptive, cross-sectional study was conducted on 220 individuals in an open population within the time frame of May-June 2015. The subjects were evaluated through the self-assessment CDQ and GQQ. The positive scores from the CDQ (≥ 4) were compared with those of the GQQ (≥ 8), to determine which of the two instruments more easily detected patients with GERD symptoms. Fifty-seven percent of the patients were men and the mean patient age was 38.1 years. Fifty percent of the subjects presented with GERD symptoms with a positive score in at least one questionnaire; 45% had positive CDQ results and 23% had positive GQQ results. Fifty-seven percent of the patients with a positive CDQ score presented with overweight/obesity, as did 72% of the patients with a positive GQQ result. Finally, 20% of the individuals had positive results for reflux symptoms in both questionnaires. There was a prevalence of GERD symptoms in 50% of the individuals studied from a general population. The GQQ detected a greater number of GERD symptoms in patients that presented with overweight/obesity and the CDQ was considered easier for patients to understand and answer. It is striking that there was only 20% agreement between the two questionnaires, suggesting that they may be useful for identifying GERD symptoms in different populations.

Dilated intercellular spaces as a marker of GERD.

PubMed

Orlando, Lori A; Orlando, Roy C

2009-06-01

Gastroesophageal reflux disease (GERD) is typically heralded by the substernal burning pain of heartburn. On endoscopic examination, about one third of GERD subjects with heartburn have erosive disease, and the remainder have nonerosive reflux disease (NERD). Unlike patients with erosive disease, those with NERD (approximately 50%) often do not respond to therapy with proton pump inhibitors (PPIs), raising the question of whether they have NERD and, if they do, whether the cause of their symptoms is similar to those who respond to PPIs. Recently, biopsies established that subjects with heartburn and PPI-responsive NERD, like those with erosive esophagitis, have lesions within the esophageal epithelium known as dilated intercellular space (DIS). In this article, we discuss the physicochemical basis for DIS in acid-injured esophageal epithelium and its significance in GERD. Although DIS is not pathognomic of GERD, it is a marker of a break in the epithelial (junctional) barrier reflecting an increase in paracellular permeability.

Systematic reviews of the literature show that the dental erosion is associated with the gastroesophageal reflux disease (GERD).The prevalence of the problem may not be exclusively similar in different countries. The purpose of this study was to investigate the association of gastro-esophageal reflux disease (GERD) with dental erosion in a sample of Iranian population regarding the standing difference in the Iranian oral hygiene and diet. Material s and Method: 140 patients with the average age of 30 to 50 years old comprised the study group. The participants were already eligible for the endoscopic examination, diagnosed by their gastroenterologist. All patients completed a detailed questionnaire regarding the medical and dental situations. After completing the questionnaire and before endoscopy, dental examination was performed by two blinded dentists.The endoscopy was then performed by a gastroenterologist and the patients were divided into three groups of healthy, suspected to GERD, and positive GERD. Data were collected and analyzed by Chi- Square test. The cross tabulation test was performed to compare the qualitative variants and discover the correlations. The statistical significance was adopted as: p < 0.05. The prevalence of dental erosion in GERD patients (22.6%) was found to be higher than the suspected (5.3%) and the healthy (7%) individuals. This study declared the GERD patients are at higher risk of developing dental erosion compared to the healthy individuals in a sample of Iranian population.

Dyspepsia and gastroesophageal reflux disease (GERD): is there any correlation?

PubMed

Simadibrata, Marcellus

2009-10-01

Dyspepsia is a syndrome characterized by symptoms and signs of upper gastrointestinal tract and the adjacent organs. It is estimated that 25% of the community have symptoms of dyspepsia syndrome. One-third of patients who visit general physician practices are patients with dyspepsia syndrome; and half of patients who visit gastroenterologists are also patients with dyspepsia syndrome. Dyspepsia syndrome and gastroesophageal reflux disease (GERD) are very prevalent in the community throughout the world.Gastroesophageal reflux disease (GERD) is more and more commonly found in daily medical practice. Until now,the natural history of disease on GERD and dyspepsia is hardly understood, even though many scientists studied both conditions and there are frequently overlapping. In an individual, GERD and dyspepsia may occur simultaneously and therefore they are hardly to be discriminated.The management of GERD is performed in keeping with Indonesia and Asia Pacific consensus, life-style modification and administering the acid suppression agents (Proton pump inhibitor (drug of choice), H2-receptor antagonist, etc),prokinetic agents (Cisapride, domperidone, etc). Life-style modification shall be performed as follows, i.e. sleep with 30-45 degree elevated head or upper chest, do not avoid sour beverages, chocolate, coffee or alcohol, avoid fat and various fried foods, sour food, less stress, stop smoking, small but frequent feeding, etc. There is a correlation between dyspepsia syndrome and gastroesophageal reflux disease(GERD), particularly between the functional dyspepsia and non-erosive gastroesophageal reflux (NERD). More appropriate definition is necessary to differentiate the dyspepsia syndrome and GERD. Further studies are needed to establish distinct definition and criteria between dyspepsia syndrome and GERD.

Clinical history, questionnaire data and response to antisecretory therapy are insufficient to make a conclusive diagnosis of GERD in isolation, but are of value in determining need for further investigation. Conclusive evidence for reflux on oesophageal testing include advanced grade erosive oesophagitis (LA grades C and D), long-segment Barrett's mucosa or peptic strictures on endoscopy or distal oesophageal acid exposure time (AET) >6% on ambulatory pH or pH-impedance monitoring. A normal endoscopy does not exclude GERD, but provides supportive evidence refuting GERD in conjunction with distal AET <4% and <40 reflux episodes on pH-impedance monitoring off proton pump inhibitors. Reflux-symptom association on ambulatory reflux monitoring provides supportive evidence for reflux triggered symptoms, and may predict a better treatment outcome when present. When endoscopy and pH or pH-impedance monitoring are inconclusive, adjunctive evidence from biopsy findings (histopathology scores, dilated intercellular spaces), motor evaluation (hypotensive lower oesophageal sphincter, hiatus hernia and oesophageal body hypomotility on high-resolution manometry) and novel impedance metrics (baseline impedance, postreflux swallow-induced peristaltic wave index) can add confidence for a GERD diagnosis; however, diagnosis cannot be based on these findings alone. An assessment of anatomy, motor function, reflux burden and symptomatic phenotype will therefore help direct management. Future GERD management strategies should focus on defining individual patient phenotypes based on the level of refluxate exposure, mechanism of reflux, efficacy of clearance, underlying anatomy of the oesophagogastric junction and psychometrics defining symptomatic presentations. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

We aimed to evaluate the prevalence of irritable bowel syndrome (IBS) in patients with typical reflux symptoms as distinguished into gastroesophageal reflux disease (GERD), hypersensitive esophagus (HE), and functional heartburn (FH) by means of endoscopy and multichannel intraluminal impedance (MII)-pH monitoring. The secondary aim was to detect pathophysiological and clinical differences between different sub-groups of patients with heartburn. Patients underwent a structured interview based on questionnaires for GERD, IBS, anxiety, and depression. Off-therapy upper-gastrointestinal (GI) endoscopy and 24 h MII-pH monitoring were performed in all cases. In patients with IBS, fecal calprotectin was measured and colonoscopy was scheduled for values >100 mg/kg to exclude organic disease. Multivariate logistic regression analysis was performed to identify independent risk factors for FH. Of the 697 consecutive heartburn patients who entered the study, 454 (65%) had reflux-related heartburn (GERD+HE), whereas 243 (35%) had FH. IBS was found in 147/454 (33%) GERD/HE but in 187/243 (77%) FH patients (P<0.001). At multivariate analysis, IBS and anxiety were independent risk factors for FH in comparison with reflux-related heartburn (GERD+HE). IBS overlaps more frequently with FH than with GERD and HE, suggesting common pathways and treatment. HE showed intermediate characteristic between GERD and FH.

This article reviews the known pathophysiological mechanisms of comorbid gastroesophageal reflux disease (GERD) in the diabetic patient, discusses therapeutic options in care, and provides an approach to its evaluation and management. We searched for review articles published in the past 10 years through a PubMed search using the filters diabetes mellitus, GERD, pathophysiology, and management. The search only yielded a handful of articles, so we independently included relevant studies from these review articles along with related citations as suggested by PubMed. We found diabetic patients are more prone to developing GERD and may present with atypical manifestations. A number of mechanisms have been proposed to elucidate the connection between these two diseases. Studies involving treatment options for comorbid disease suggest conflicting drug-drug interactions. Currently, there are no published guidelines specifically for the evaluation and management of GERD in the diabetic patient. Although there are several proposed mechanisms for the higher prevalence of GERD in the diabetic patient, this complex interrelationship requires further research. Understanding the pathophysiology will help direct diagnostic evaluation. In our review, we propose a management algorithm for GERD in the diabetic patient. © 2015 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

Background Despite increasing cancer burden in Malawi, pathology services are limited. We describe operations during the first 20 months of a new pathology laboratory in Lilongwe, with emphasis on cancer diagnoses. Methods and Findings We performed a cross-sectional study of specimens from the Kamuzu Central Hospital pathology laboratory between July 1, 2011 and February 28, 2013. Patient and specimen characteristics, and final diagnoses are summarized. Diagnoses were categorized as malignant, premalignant, infectious, other pathology, normal or benign, or nondiagnostic. Patient characteristics associated with premalignancy and malignancy were assessed using logistic regression. Of 2772 specimens, 2758 (99%) with a recorded final diagnosis were included, drawn from 2639 unique patients. Mean age was 38 years and 63% were female. Of those with documented HIV status, 51% had unknown status, and 36% with known status were infected. Histologic specimens comprised 91% of cases, and cytologic specimens 9%. Malignant diagnoses were most common overall (n = 861, 31%). Among cancers, cervical cancer was most common (n = 117, 14%), followed by lymphoma (n = 91, 11%), esophageal cancer (n = 86, 10%), sarcoma excluding Kaposi sarcoma (n = 75, 9%), and breast cancer (n = 61, 7%). HIV status was known for 95 (11%) of malignancies, with HIV prevalence ranging from 9% for breast cancer to 81% for cervical cancer. Increasing age was consistently associated with malignancy [bivariable odds ratio 1.24 per decade increase (95% CI 1.19–1.29) among 2685 patients with known age; multivariable odds ratio 1.33 per decade increase (95% CI 1.14–1.56) among 317 patients with known age, gender, and HIV status], while HIV infection and gender were not. Conclusions Despite selection and referral bias inherent in these data, a new pathology laboratory in Lilongwe has created a robust platform for cancer care and research.

Venous infarction of a leiomyoma is known as red degeneration of leiomyoma (RDL) and can be a cause of acute abdomen. Although magnetic resonance imaging (MRI) is the only modality that can depict the inner condition of a leiomyoma, the typical MR findings of RDL are sometimes identified incidentally even in asymptomatic patients. The purpose of this study is to clarify common pathological findings of uterine tumors preoperatively diagnosed as RDL by MRI. We diagnosed 28 cases of RDL by MRI from March 2007 to April 2015. The ten lesions subjected to pathological analysis after resection were included in the study and reviewed by a gynecological pathologist. The average time from MRI to operation was 4.7 months. The typical beefy-red color was not observed on the cut surface of the tumor except in one tumor resected during the acute phase. All lesions diagnosed as RDL by MRI had common pathological findings consistent with red degeneration of leiomyoma, including coagulative necrosis. Other common pathological features of RDL besides extensive coagulative necrosis appear to be a lack of inflammatory cell infiltrate or hemorrhage in the entire lesion. Although RDL is known to cause acute abdomen, its typical MR findings can be observed even in asymptomatic patients in a condition that manifests long after red degeneration. The characteristic pathological findings in both the acute phase and the chronic phase that we found in this study, along with radiology reports, will be helpful references for gynecologists and pathologists in suspecting a history of red degeneration and confirming the diagnosis.

Itopride is a newly developed prokinetic agent, which enhances gastric motility through both antidopaminergic and anti-acetylcholinesterasic actions. The importance of esophageal motor dysfunction in the pathogenesis of gastro-esophageal reflux disease (GERD) makes it interesting to examine the effect of itopride on esophageal acid exposure. The effect of itopride on esophageal acid reflux variables for 24 h was studied in 26 patients with GERD symptoms, pre-entry total acid exposure time (pH<4) of more than 5% and mild esophagitis (Savary-Miller grades I, II) proven by endoscopy. Ambulatory 24-h pH-metry and symptom assessment were performed after treatments with 150 or 300 mg itopride thrice a day (t.i.d.) for 30 d in random order, using an open label method. For evaluating the safety of itopride, blood biochemical laboratory test was performed and the serum prolactin level was also examined before and after treatment. Total symptom score was significantly decreased after treatment in 150- or 300-mg group. Itopride 300 mg was significantly effective than 150 mg on decreasing the total per cent time with pH<4, total time with pH<4 and DeMeester score. No serious adverse effects were observed with administration of itopride in both groups. Itopride 100 mg t.i.d. is effective on decreasing pathologic reflux in patient with GERD and therefore it has the potential to be effective in the treatment of this disease.

Symptoms of infantile gastroesophageal reflux disease (GERD) may overlap with oropharyngeal dysphagia, but the evaluation and treatment of these conditions vary greatly. In this investigation, the incidence of oropharyngeal dysphagia in infants with GERD-like symptoms is determined. A retrospective chart review was performed on infants referred to a pediatric gastroenterology clinic for GERD-like symptoms. A feeding screen was performed in all infants. Standardized bedside swallow evaluation and modified barium swallow (MBS) studies were then performed when clinically indicated. A similarly aged cohort of normal participants also underwent a standard bedside swallow evaluation for group comparison. Study population included 67 infants. A swallow evaluation was recommended in 39 of 67 infants with abnormalities noted in all. Swallowing abnormalities were more frequent and clustered in infants with GERD-like symptoms vs controls. MBS was abnormal in 16 of 17 qualifying infants. Characteristics of at-risk infants included extreme prematurity, developmental delay, or symptoms refractory to antireflux medications. Oropharyngeal dysphagia is prominent in infants with GERD-like symptoms.

Unfortunately, the identification of patients with GERD who aspirate still lacks clear diagnostic indicators. The authors hypothesized that symptoms of GERD and detection of pepsin and bile acids in the bronchoalveolar lavage fluid (BAL) and exhaled breath condensate (EBC) are effective for identifying lung transplantation patients with GERD-induced aspiration. From November 2009 to November 2010, 85 lung transplantation patients undergoing surveillance bronchoscopy were prospectively enrolled. For these patients, self-reported symptoms of GERD were correlated with levels of pepsin and bile acids in BAL and EBC and with GERD status assessed by 24-h pH monitoring. The sensitivity and specificity of pepsin and bile acids in BAL and EBC also were compared with the presence of GERD in 24-h pH monitoring. The typical symptoms of GERD (heartburn and regurgitation) had modest sensitivity and specificity for detecting GERD and aspiration. The atypical symptoms of GERD (aspiration and bronchitis) showed better identification of aspiration as measured by detection of pepsin and bile acids in BAL. The sensitivity and specificity of pepsin in BAL compared with GERD by 24-h pH monitoring were respectively 60 and 45 %, whereas the sensitivity and specificity of bile acids in BAL were 67 and 80 %. These data indicate that the measurement of pepsin and bile acids in BAL can provide additional data for identifying lung transplantation patients at risk for GERD-induced aspiration compared with symptoms or 24-h pH monitoring alone. These results support a diagnostic role for detecting markers of aspiration in BAL, but this must be validated in larger studies.

NEED AND PURPOSE: The scarcity of literature and lack of published guidelines on gastroesophageal reflux disease (GERD) from India, have necessitated this review. A literature search in PubMed was conducted with regard to epidemiology, clinical features, investigation and management of GERD in children. English language studies published full over the last 20 years were considered and relevant information was extracted. Nearly half of all healthy babies regurgitate at least once a day by 4 months of age and this subsides in 90% of them by 1 year. In contrast, GERD prevalence increases with age and by adolescence it is similar to adults (20%). While regurgitation in infancy does not need investigation or therapy, empirical proton pump inhibitor (PPI) for 4 weeks is justified in older children with classical GERD symptoms. There is no gold-standard investigation for GERD. A pH study with or without impedance is useful in extraesophageal manifestations and endoscopy in esophagitis. Proton pump inhibitors (PPI) play a pivotal role in the management of GERD and its long-term use has been shown to be safe in children. Antireflux surgery plays a minor role due to, its associated morbidity and high failure rate, especially in the high risk group who needs it most. Regurgitation in infancy need not be investigated unless there are warning features. Empirical PPI therapy is justified in older children and adolescents with typical reflux symptoms. pH study in extraesophageal manifestations and endoscopy for esophagitis are the investigations of choice. PPI is the mainstay of therapy in GERD.

The growing importance of symptom assessment is evident from the numerous clinical studies on gastroesophageal reflux disease (GERD) assessing treatment-induced symptom relief. However, to date, the a priori selection of criteria defining symptom relief has been arbitrary. The present study was designed to prospectively identify GERD symptom thresholds for the broad spectrum of GERD-related symptoms assessed by the validated reflux questionnaire (ReQuest) and its subscales, ReQuest-GI (gastrointestinal symptoms) and ReQuest-WSO (general well-being, sleep disturbances, other complaints), in individuals without evidence of GERD. In this 4-day evaluation in Germany, 385 individuals without evidence of GERD were included. On the first day, participants completed the ReQuest, the Gastrointestinal Symptom Rating Scale, and the Psychological General Well-Being scale. On the other days, participants filled in the ReQuest only. GERD symptom thresholds were calculated for ReQuest and its subscales, based on the respective 90th percentiles. GERD symptom thresholds were 3.37 for ReQuest, 0.95 for ReQuest-GI, and 2.46 for ReQuest-WSO. Even individuals without evidence of GERD may experience some mild symptoms that are commonly ascribed to GERD. GERD symptom thresholds derived in this study can be used to define the global symptom relief in patients with GERD. Copyright 2007 S. Karger AG, Basel.

Background The GerdQ scoring system may be a useful tool for managing gastro-oesophageal reflux disease. However, GerdQ has not been fully validated in Asian countries. Objective To validate the Japanese version of GerdQ and to compare this version to the Carlsson-Dent questionnaire (CDQ) in both general and hospital-based populations. Methods The questionnaires, including the Japanese versions of GerdQ and CDQ, and questions designed to collect demographic information, were sent to a general population via the web, and to a hospital-based population via conventional mail. The optimal cutoff GerdQ score and the differences in the characteristics between GerdQ and CDQ were assessed. Results The answers from 863 web-responders and 303 conventional-mail responders were analysed. When a GerdQ cutoff score was set at 8, GerdQ significantly predicted the presence of reflux oesophagitis. Although the GerdQ scores were correlated with the CDQ scores, the concordance rates were poor. Multivariate analysis results indicated that, the additional use of over-the-counter medications was associated with GerdQ score ≥ 8, but not with CDQ score ≥ 6. Conclusions The GerdQ cutoff score of 8 was appropriate for the Japanese population. Compared with CDQ, GerdQ was more useful for evaluating treatment efficacy and detecting patients’ unmet medical needs. PMID:24917957

Baseline impedance measured with ambulatory impedance pH monitoring (MII-pH) and a mucosal impedance catheter detects gastroesophageal reflux disease (GERD). However, these tools are limited by cost or patient tolerance. We investigated whether baseline impedance measured during high-resolution impedance manometry (HRIM) distinguishes GERD patients from controls. Consecutive patients with clinical HRIM and MII-pH testing were identified. Gastroesophageal reflux disease was defined by esophageal pH <4 for ≥5% of both the supine and total study time, whereas controls had an esophageal pH <4 for ≤3% of the study performed off PPI. Baseline impedance was measured over 15 seconds during the landmark period of HRIM and over three 10 minute intervals during the overnight period of MII-pH. Among 29 GERD patients and 26 controls, GERD patients had a mean esophageal acid exposure time of 22.7% compared to 1.2% in controls (P<.0001). Mean baseline impedance during HRIM was lower in GERD (1061 Ω) than controls (2814 Ω) (P<.0001). Baseline mucosal impedance measured during HRIM and MII-pH correlated (r=0.59, P<.0001). High-resolution esophageal manometry baseline impedance had high diagnostic accuracy for GERD, with an area under the curve (AUC) of 0.931 on receiver operating characteristics (ROC) analysis. A HRIM baseline impedance threshold of 1582 Ω had a sensitivity of 86.2% and specificity of 88.5% for GERD, with a positive predictive value of 89.3% and negative predictive value of 85.2%. Baseline impedance measured during HRIM can reliably discriminate GERD patients with at least moderate esophageal acid exposure from controls. This diagnostic tool may represent an accurate, cost-effective, and less invasive test for GERD. © 2016 John Wiley & Sons Ltd.

Refractory heartburn despite acid suppression may be explained by ongoing gastroesophageal reflux disease (GERD) or functional heartburn (FH), i.e., symptoms without evidence of GERD. Impedance-pH monitoring (impedance-pH) detects acid and nonacid reflux and is useful for evaluating acid-suppressed, refractory patients. Intercellular space diameter (ISD) of esophageal epithelium measured by transmission electron microscopy (TEM) is a marker of epithelial damage present in both erosive and nonerosive reflux disease. ISD has not been used to study refractory heartburn or FH. Our aim was to compare ISD in healthy controls and refractory heartburn patients with GERD and FH. In refractory heartburn patients (heartburn more than twice/week for at least 2 months despite proton pump inhibitor (PPI) b.i.d.), erosive esophagitis and/or abnormal impedance-pH (increased acid exposure or positive symptom index) defined GERD; normal esophagogastroduodenoscopy (EGD)/impedance-pH defined FH. Asymptomatic, healthy controls had normal EGD and pH-metry. Mean ISD in each subject, determined by blinded TEM of esophageal biopsies, was the average of 100 measurements (10 measurements in each of 10 micrographs). In all, 11 healthy controls, 11 FH, and 15 GERD patients were studied. Mean ISD was significantly higher in GERD compared with controls (0.87 vs. 0.32 μm, P=0.003) and FH (0.87 vs. 0.42 μm, P=0.012). Mean ISD was similar in FH and controls (0.42 vs. 0.32 μm, P=0.1). The proportion of patients with abnormal ISD was significantly higher for GERD compared with FH (60 vs. 9%, P=0.014). ISD is increased in refractory heartburn patients with GERD but not those with FH. Our findings suggest that measurement of ISD by TEM might be a useful tool to distinguish GERD from FH in patients with refractory heartburn.

The objective of this study was to define the rates of discrepancy between outside pathological diagnoses and secondary reviews. We assessed the rates of discordance between outside diagnoses and secondary reviews, categorizing by organ site and minor or major (affecting patient care) discordances. A total of 9,289 consecutive surgical pathology (SP) and cytopathology (CP) cases reviewed in 2015 were identified. For 8,191 outside SP cases reviewed, the overall discordance rate (DR) was 14.2% (2.2% major, 12.0% minor). Specifically, neuropathology had the highest DR (10.9%), cutaneous and breast the lowest (1.1% each). Among 1,098 CP cases, the total DR was 13.7% (3.0% major, 10.7% minor). The majority of CP cases (1,066) were non-gynecological and had a total DR of 13.4% (2.7% major, 10.7% minor). While major DR was low, certain subspecialties had high DRs. This project can help identify areas where focused education could help improve pathological diagnostic accuracy for cancer.

Gastroesophageal reflux disease (GERD) is associated with many respiratory disorders, among which, chronic cough, laryngitis, and asthma are among the most common. We investigated lung function, including gas diffusion capacity, in children with poor asthma control or chronic laryngitis with untreated GERD. A total of 71 children, aged 6-17 years, with chronic respiratory and other symptoms suggestive for GERD, were enrolled and divided into 2 groups: chronic laryngitis and asthma. Participants underwent 24-hour pH monitoring and lung function assessment, measurement of single-breath diffusing capacity of the lung for carbon monoxide (DLCO), and fraction of exhaled nitric oxide (FENO) measurement. 24-hour pH monitoring was positive for GERD in 92.1% of preselected children with asthma and 90.1% of children with chronic recurrent laryngitis. All flows (PEF, MEF75, MEF50, and MEF25) were significantly lower in the asthma group, while FENO and DLCO were significantly lower in the laryngitis group. A significant inverse relationship was found between DLCO and all reflux indexes in the laryngitis group. Each unit change of Johnson-DeMeester score and Boix-Ochoa score increased the odds for significantly lower DLCO in laryngitis patients by 3.9% and 5.5%, respectively. In children with uncontrolled asthma and chronic laryngitis, the regurgitation of gastric contents due to GERD contributes to poor asthma control and aggravation of chronic laryngitis. Despite having normal lung function, the gas diffusion capacity should be controlled in patients with GERD and chronic laryngitis, and it might be the very first abnormality in distal airways.

We can place Kant as one of the pillars of contemporary medicine. Firstly, as an Illuminist, his work subordinates the collection of empirical data, which in medical science is constitutional to reason. This was the basis of a rational medical science. Secondly, he is the father of medical regulation, having set the philosophical control ground stone for physicians by the State. His work "Critique of Practical Reason" drafts all the future codes of ethics and bioethics. We will hereby study his relationship with medicine based on the text "The Conflict with the Faculty of Medicine" and other auxiliary texts.We can find in Kant's works the description of a series of symptoms that were related to a nonspecific dyspeptic syndrome that nowadays would be diagnosed as a strong indication that he suffered from gastroesophageal reflux disease (GERD).

Stretta procedure (0 vs. 19.4%, p = 0.006). Conclusions MII-pH monitoring effectively detected respiratory-related predictive parameters, including total/proximal reflux episodes and symptom correlations. We found that GERD patients with respiratory symptoms exhibited more proximal and total reflux episodes but not more acid-related episodes, as determined by MII-pH monitoring. Thus, such monitoring could be useful for diagnosing atypical GERD patients with respiratory symptoms. Furthermore, LTF exhibited a more significant effect on controlling typical symptoms in all GERD patients and reducing the recurrence rate than the Stretta procedure in patients with respiratory symptoms.

Bringing GERD Management up to PAR-2.

Souza, Rhonda F

Proton pump inhibitors (PPIs) are extremely effective for mucosal healing of reflux esophagitis, but less so for relieving the symptom of heartburn. PPIs block the secretion of gastric acid, the caustic effects of which have been assumed to be the primary culprit in the pathogenesis of reflux esophagitis. However, mounting data suggest that reflux-stimulated, immune-mediated mechanisms may underlie the development of esophagitis in patients with gastroesophageal reflux disease (GERD). Thus, the future of GERD therapy, particularly for patients who are refractory to PPIs, may be the targeting of proteins such as proteinase-activated receptor-2, which have central roles in the generation of immune-mediated esophageal mucosal damage and in eliciting the symptom of heartburn.

Suture and staple-based endoluminal devices for gastroesophageal reflux disease (GERD) and obesity have failed to demonstrate long-term efficacy. To demonstrate the feasibility of mucosal excision and full-thickness suture apposition of the excision beds to create sufficient scar tissue formation at the gastroesophageal junction for the intraluminal treatment of GERD or obesity. Survival animal experiments. Seven mongrel dogs. Interventions. Under general endotracheal anesthesia, a Barostat test was performed on 4 dogs. A mucosal excision device was introduced through the esophagus into the proximal stomach. Two to 4 mucosal excisions were performed on all dogs at or just below the gastroesophageal junction and the mucosal pieces were removed. After hemostasis, an intraluminal suturing instrument was introduced and either 2 or 4 sutures were placed through the excision beds to bring them into apposition. These were tied and the suture strands cut. All dogs were survived for 2 months. End-term endoscopies were performed, and a repeat Barostat procedure was performed on the animals undergoing an antireflux procedure. After euthanasia the stomachs were explanted, examined, photographed, and sectioned for histologic examination. All dogs survived without complication. In the 4 GERD dogs, the Barostat studies demonstrated a significant decrease in gastroesophageal junction compliance. In the 3 dogs undergoing the obesity procedure, the gastric outlet apposition to a 6-mm endoscope was satisfactory with full insufflation and the desired scarring was seen on histologic examination. It is possible to create adequate gastroesophageal junction scarring for the treatment of GERD and obesity. A clinical pilot study will be initiated.

We investigated factors related to proton pump inhibitor (PPI) -refractory gastroesophageal reflux disease (GERD) symptoms, particularly with respect to acid, the CYP2C19 genotype and psychological aspects. Patients with an Frequency Scale for the Symptoms of GERD (FSSG) score of ≥8 after the initial treatment were switched to therapy with rabeprazole at a dose of 20 mg once daily for eight weeks. We investigated the rate of improvement in PPI-refractory GERD symptoms, background factors, the Hospital Anxiety and Depression Scale (HADS) score and the CYP2C19 genotype. Patients Sixty patients endoscopically diagnosed with reflux esophagitis within the past six months who had received omeprazole at a dose of 20 mg once daily for eight weeks or longer were enrolled. In 71.6% of the patients, the FSSG score decreased to <8 after treatment with omeprazole at a dose of 20 mg once daily for ≥8 weeks, resulting in improvements in their GERD symptoms. Significant factors related to omeprazole-refractory GERD symptoms included a longer disease duration (p=0.0004) and higher HADS score (p=0.01). Among the omeprazole-refractory cases, only 23.5% of the patients showed symptom improvement after switching to rabeprazole. There were no significant differences in the average scores for FSSG (p=0.089) or HADS (p=0.182), before or after the drug change. A total of 92% of the rabeprazole poor responders were homo/hetero extensive metabolizers for the CYP2C19 genotype. Our findings suggest that switching the PPI from omeprazole (20 mg once daily) to rabeprazole (20 mg once daily) is not a significant effective therapeutic strategy for improving PPI-refractory GERD symptoms, taking into consideration possible psychometric factors and patients who require stronger acid suppression than that achieved with a double dose of PPIs for PPI-refractory GERD symptoms.

Gastroesophageal reflux disease (GERD) represents one of the most common gastrointestinal disorders, but is still a challenge to cure. Proton pump inhibitors (PPIs) are currently the GERD's standard treatment, although not successful in all patients; some concerns have been raised regarding their long term consumption. Recently, some studies showed the benefits of inspiratory muscle training in increasing the lower esophageal sphincter pressure in patients affected by GERD, thereby reducing their symptoms. Relevant published studies were searched in Pubmed, Google Scholar, Ovid or Medical Subject Headings using the following keywords: "GERD" and physiotherapy", "GERD" and "exercise", "GERD" and "breathing", "GERD and "training". At the end of our selection process, four publications have been included for systematic review. All of them were prospective controlled studies, mainly based on the training of the diaphragm muscle. GERD symptoms, pH-manometry values and PPIs usage were assessed. Among the non-surgical, non-pharmacological treatment modalities, the breathing training on diaphragm could play an important role in selected patients to manage the symptoms of GERD.

Background A Stanford University study reported that in asymptomatic GERD patients who were being treated with a proton pump inhibitor (PPI), 50% had pathologic esophageal acid exposure. Aim We considered the possibility that the high prevalence of pathologic esophageal reflux might simply have resulted from calculating acidity as time pH < 4. Methods We calculated integrated acidity and time pH < 4 from the 49 recordings of 24-hour gastric and esophageal pH from the Stanford study as well as from another study of 57 GERD subjects, 26 of whom were treated for 8 days with 20 mg omeprazole or 20 mg rabeprazole in a 2-way crossover fashion. Results The prevalence of pathologic 24-hour esophageal reflux in both studies was significantly higher when measured as time pH < 4 than when measured as integrated acidity. This difference was entirely attributable to a difference between the two measures during the nocturnal period. Nocturnal gastric acid breakthrough was not a useful predictor of pathologic nocturnal esophageal reflux. Conclusion In GERD subjects treated with a PPI, measuring time esophageal pH < 4 will significantly overestimate the prevalence of pathologic esophageal acid exposure over 24 hours and during the nocturnal period.

Gastroesophageal reflux disease (GERD) has in recent times become an important public health issue owing to the considerable health care resources utilized in its management, its deleterious effect on quality of life and the increasing prevalence of a relatively rare complication of reflux disease - esophageal adenocarcinoma. We review here the major current challenges in the field of reflux disease and its complications, and provide some approaches that may be useful in management. The issues to be faced include the very limited comprehension of the reasons behind the increasing prevalence of the disease, difficulties in correlating symptoms with objective data of pathological gastroesophageal reflux and the relatively unsophisticated tools we are employing to investigate the underlying pathophysiology. It is certain that the lack of well-defined and characterized methodologies to compare the effects of therapy require the development of more effective questionnaire-type analytic tools. In regard to treatment, there is little doubt that the widely prescribed proton pump inhibitors have dose-equivalent efficacy and are the most highly effective agents capable of suppressing acid, controlling many of the symptoms of GERD and healing erosions. Nevertheless, many patients continue to experience symptoms on withdrawal or at night. Pharmacological agents that can effectively increase lower esophageal sphincter pressure or promote motility are as yet unavailable. Although the introduction of laparoscopic techniques has resulted in a modest revival in surgical intervention using a variety of 'wrap-type' operations, the indications are few and the procedure is associated with a significant morbidity and even mortality especially if the expertise of the surgeon is an issue. Endoscopic techniques of regulating reflux are at this time experimental and not applicable to the general population. Intestinal metaplasia in the lower esophagus is probably very common.

The goal of this systematic review by the American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee was to derive recommendations from the medical literature regarding the surgical treatment of pediatric gastroesophageal reflux disease (GERD). Five questions were addressed by searching the MEDLINE, Cochrane, Embase, Central, and National Guideline Clearinghouse databases using relevant search terms. Consensus recommendations were derived for each question based on the best available evidence. There was insufficient evidence to formulate recommendations for all questions. Fundoplication does not affect the rate of hospitalization for aspiration pneumonia, apnea, or reflux-related symptoms. Fundoplication is effective in reducing all parameters of esophageal acid exposure without altering esophageal motility. Laparoscopic fundoplication may be comparable to open fundoplication with regard to short-term clinical outcomes. Partial fundoplication and complete fundoplication are comparable in effectiveness for subjective control of GERD. Fundoplication may benefit GERD patients with asthma, but may not improve outcomes in patients with neurologic impairment or esophageal atresia. Overall GERD recurrence rates are likely below 20%. High-quality evidence is lacking regarding the surgical management of GERD in the pediatric population. Definitive conclusions regarding the effectiveness of fundoplication are limited by patient heterogeneity and lack of a standardized outcomes reporting framework.

Gastro-esophageal reflux disease (GERD) is the most common digestive disease in industrialized countries (Europe and North America) and is associated with microscopic changes in the squamous epithelium. However, biopsy is not presently included in the routine diagnostic flow chart of GERD. In contrast, esophageal biopsy is mandatory when diagnosing Barrett's esophagus. High quality histology reports are necessary to provide information on diagnosis and can also be important for research and epidemiological studies. It has been evident for decades that pathology reports vary between institutions and even within a single institution. Standardization of reporting is the best way to ensure that information necessary for patient management is included in pathology reports. This paper details the histological criteria for diagnosing GERD-associated microscopic esophagitis, other forms of esophagitis with specific features and columnar metaplasia in the lower esophagus (Barrett's esophagus). It provides a detailed description of appropriate sampling criteria, individual lesions and how they contribute to the histology report. Copyright © 2011 Editrice Gastroenterologica Italiana S.r.l.

Gastro-esophageal reflux disease (GERD) impairs quality of life; however, the association between GERD and work productivity has not been well investigated in Japan. This study was designed to compare the impact of GERD on productivity between Japanese workers with GERD symptoms that persisted vs resolved on medical therapy. A cross-sectional Web-based survey was conducted in workers. The impact of GERD on work and daily productivity was evaluated using a Web-reported Work Productivity and Activity Impairment Questionnaire for patients with GERD and a GERD symptom severity Questionnaire. Demographic information, clinical history, and satisfaction with GERD medication were also ascertained. A total of 20 000 subjects were invited to the survey. After the exclusion of patients with a history of gastrointestinal (GI) malignancy, peptic ulcer, upper GI surgery, and unemployment, 650 participants were included in the analysis. Participants with persistent GERD symptoms reported a significantly greater losses of work productivity (11.4 ± 13.4 h/week), absenteeism (0.7 ± 3.1 h/week), presenteeism (10.7 ± 12.6 h/week), costs (20 100 ± 26 800 JPY/week), and lower daily productivity (71.3% [95% confidence interval, 69.0-73.7]) than those whose symptoms were alleviated with medications. The level of dissatisfaction with GERD medications among participants with persistent GERD symptoms was significantly correlated with loss of work and daily productivity (p < 0.001). GERD places a significant burden on work and daily productivity despite medical therapy. Ineffective GERD therapy is associated with greater productivity loss. © 2014 John Wiley & Sons Ltd.

AIM To evaluate the psychometric properties of a newly developed questionnaire, known as the gastroesophageal reflux and dyspepsia therapeutic efficacy and satisfaction test (GERD-TEST), in patients with GERD. METHODS Japanese patients with predominant GERD symptoms recruited according to the Montreal definition were treated for 4 wk using a standard dose of proton pump inhibitor (PPI). The GERD-TEST and the Medical Outcome Study Short Form-8 Health Survey (SF-8) were administered at baseline and after 4 wk of treatment. The GERD-TEST contains three domains: the severity of GERD and functional dyspepsia (FD) symptoms (5 items), the level of dissatisfaction with daily life (DS) (4 items), and the therapeutic efficacy as assessed by the patients and medication compliance (4 items). RESULTS A total of 290 patients were eligible at baseline; 198 of these patients completed 4 wk of PPI therapy. The internal consistency reliability as evaluated using the Cronbach’s α values for the GERD, FD and DS subscales ranged from 0.75 to 0.82. The scores for the GERD, FD and DS items/subscales were significantly correlated with the physical and mental component summary scores of the SF-8. After 4 wk of PPI treatment, the scores for the GERD items/subscales were greatly reduced, ranging in value from 1.51 to 1.87 and with a large effect size (P < 0.0001, Cohen’s d; 1.29-1.63). Statistically significant differences in the changes in the scores for the GERD items/subscales were observed between treatment responders and non-responders (P < 0.0001). CONCLUSION The GERD-TEST has a good reliability, a good convergent and concurrent validity, and is responsive to the effects of treatment. The GERD-TEST is a simple, easy to understand, and multifaceted PRO instrument applicable to both clinical trials and the primary care of GERD patients. PMID:28811716

To evaluate the psychometric properties of a newly developed questionnaire, known as the gastroesophageal reflux and dyspepsia therapeutic efficacy and satisfaction test (GERD-TEST), in patients with GERD. Japanese patients with predominant GERD symptoms recruited according to the Montreal definition were treated for 4 wk using a standard dose of proton pump inhibitor (PPI). The GERD-TEST and the Medical Outcome Study Short Form-8 Health Survey (SF-8) were administered at baseline and after 4 wk of treatment. The GERD-TEST contains three domains: the severity of GERD and functional dyspepsia (FD) symptoms (5 items), the level of dissatisfaction with daily life (DS) (4 items), and the therapeutic efficacy as assessed by the patients and medication compliance (4 items). A total of 290 patients were eligible at baseline; 198 of these patients completed 4 wk of PPI therapy. The internal consistency reliability as evaluated using the Cronbach's α values for the GERD, FD and DS subscales ranged from 0.75 to 0.82. The scores for the GERD, FD and DS items/subscales were significantly correlated with the physical and mental component summary scores of the SF-8. After 4 wk of PPI treatment, the scores for the GERD items/subscales were greatly reduced, ranging in value from 1.51 to 1.87 and with a large effect size ( P < 0.0001, Cohen's d ; 1.29-1.63). Statistically significant differences in the changes in the scores for the GERD items/subscales were observed between treatment responders and non-responders ( P < 0.0001). The GERD-TEST has a good reliability, a good convergent and concurrent validity, and is responsive to the effects of treatment. The GERD-TEST is a simple, easy to understand, and multifaceted PRO instrument applicable to both clinical trials and the primary care of GERD patients.

Medical therapy of gastroesophageal reflux disease (GERD) is based on the use of proton pump inhibitors (PPIs) as first choice treatment. Despite their effectiveness, about 20-30% of patients report an inadequate response and alternative drugs are required. Areas covered: This review provides an overview of current pharmacotherapy for treating GERD by showing the results of PPIs, reflux inhibitors, antidepressants and mucosa protective medications. Expert opinion: Medical therapy of GERD does not definitely cure the disease, because even PPIs are not able to change the key factors responsible for it. However, they remain the mainstay of medical treatment, allowing us to alleviate symptoms, heal esophagitis and prevent complications in the majority of cases. Nevertheless, many patients do not respond, because acid does not play any pathogenetic role. Prokinetics and reflux inhibitors have the potential to control motor abnormalities, but the results of clinical trials are inconsistent. Antidepressant drugs are effective in specific subgroups of NERD patients with visceral hypersensitivity, but larger, controlled clinical studies are necessary. Protective drugs or medical devices have been recently adopted to reinforce mucosal resistance and preliminary trials have confirmed their efficacy either combined with or as add-on medication to PPIs in refractory patients.

Gastroesophageal reflux disease (GERD) is one of the most common diagnoses in a gastroenterologist's practice. Gastroesophageal reflux (GER) describes the retrograde movement of gastric contents through the lower oesophageal sphincter (LES) to the oesophagus. GER can occur physiologically and may be accompanied by symptoms. The introduction of endoscopes and ambulatory devices for continuous monitoring of oesophageal pH (24 h pH monitoring) has led to great improvement in the ability to diagnose reflux disease and reflux-associated complications. The development of pathological reflux and GERD can be attributed to many factors. Pathophysiology of GERD includes transient lower oesophageal sphincter relaxations (TLESRs), incompetent LES because of a decreased lower oesophageal sphincter pressure (LESP) and deficient or delayed oesophageal acid clearance. Uncomplicated GERD may be treated by modification of lifestyle and eating habits in an early stage of GERD. The various agents currently used for treatment of GERD include mucoprotective substances, antacids, H2-blockers, prokinetics and proton pump inhibitors (PPIs). Although these drugs are effective, they do not necessarily influence the underlying causes of the disease by improving the oesophageal clearance, increasing the LESP or reducing the frequency of TLESRs. The following article gives an overview regarding current concepts of the pathophysiology and pharmacological treatment of GERD stressing on pharmacoeconomic issues of the treatment and discusses the advantages and disadvantages for step-up and step-down therapy.

The primary objective was to assess gastroesophageal reflux disease (GERD) symptom resolution rates with esomeprazole by erosive esophagitis (EE) status, and the secondary objective was to evaluate potential predictors of the presence of EE and heartburn resolution. Patients with GERD who have EE have higher reported symptom resolution rates than those with nonerosive reflux disease (NERD) when treated with proton pump inhibitors (PPIs). This open-label multicenter study included adults with GERD symptoms. Patients were stratified by EE status after endoscopy and received once-daily esomeprazole 40 mg for 4 weeks. Questionnaires determined symptom response rates, and baseline predictors of EE or heartburn resolution were evaluated. Potential predictors, including years with GERD, history of EE, and time to relief with antacids, were examined. Heartburn resolution rates at 4 weeks were higher for patients with EE than NERD (69% [124/179] vs. 48% [85/177]; p < 0.0001). Multivariate models had moderate predictive ability for EE (c-index, 0.76) and poor predictive ability (c-index, 0.57) for heartburn resolution. However, faster heartburn relief with antacid use, particularly within 15 min, was predictive of EE and heartburn resolution. Patients with EE have higher heartburn resolution rates than patients with NERD after treatment, although recall bias may be possible. Fast relief with antacid use is predictive of EE and heartburn resolution with a PPI and suggests that a history of antacid relief may provide corroborative evidence to empiric PPI therapy in determining whether patients with heartburn have acid reflux disease.

A standard chemotherapy for recurrent/metastatic salivary gland cancers has not been established. Combination chemotherapy of carboplatin and paclitaxel should be evaluated as a treatment option. This study retrospectively reviewed salivary gland cancer patients who received combination chemotherapy of carboplatin and paclitaxel. The differences in objective responses and in the prognoses according to the different pathological diagnoses were evaluated. A total of 38 patients were enrolled in the study; of them, 18 had salivary duct carcinomas (SDCs), nine had adenoid cystic carcinomas (ACCs), and 11 had other pathological diagnoses. Objective responses were observed in 15 (39%) patients. The median progression-free survival (PFS) was 6.5 months, and the median overall survival (OS) was 26.5 months. ACC patients had relatively low response rates (9%), but there were no significant differences in PFS or OS compared to other sub-types. The treatment was well tolerated, with few adverse events. Salivary gland cancer patients showed a moderate clinical response to the combination chemotherapy of carboplatin and paclitaxel. The objective response rates differed according to the pathological diagnoses, but there were no significant differences in prognoses.

While there is evidence that physiological data correlate poorly with quality-of-life data or patient-perceived symptom severity, most outcome studies of antireflux surgery still refer physiologic criteria. The aim of this prospective study was to establish whether concomitant aerophagia in GERD (gastroesophageal reflux disease) patients might influence the surgical outcome of laparoscopic 'floppy' Nissen fundoplication. A total of 112 patients were divided into 2 subgroups: group 1 comprising GERD patients without aerophagia (n = 94; 84%); group 2 of GERD patients with concomitant aerophagia (n = 28; 16%). In all patients, requirements for surgery included an evaluation of symptoms (list of 17 symptoms; patients' grading from no--mild to moderate--severe), quality of life (Gastrointestinal Quality of Life Index: GIQLI), esophagogastroduodenoscopy, esophageal manometry and 24-h pH monitoring. Additionally, we asked for any potential stress relations to GERD symptoms. Surgical outcome was assessed 3 months and 1 year postoperatively. In group 2 patients before surgery, we found a significantly higher percentage with a mild impairment of esophageal motility, with a subjectively and objectively dominant reflux in the upright position, with a lower grading of esophagitis or Barrett esophagus, and with a stronger belief that stress was in any relation to perceived symptoms compared with group 1 patients. Additionally, these patients perceived typical and untypical symptoms more intensively. Factors such as DeMeester score and lower esophageal sphincter pressure did not differ preoperatively, the same as after antireflux surgery. Both groups profit significantly from surgery-a continuous reduction of symptom severity and quality-of-life improvement was found. Group 1 patients showed an improvement in mean GIQLI from 93.4+/-8.3 points preoperatively to 123.1+/-7.3 and 122.9+/-9.0 points 3 months and 1 year postoperatively, whereas group 2 patients demonstrated a lower

Antireflux therapy may lead to recovery of impaired mucosal integrity in gastro-esophageal reflux disease (GERD) patients as reflected by an increase in baseline impedance. The study objective was to evaluate the effect of endoscopic fundoplication and proton pump inhibitor (PPI) PPI therapy on baseline impedance and heartburn severity in GERD patients. Forty-seven GERD patients randomized to endoscopic fundoplication (n = 32) or PPI therapy (n = 15), and 29 healthy controls were included. Before randomization and 6 months after treatment, baseline impedance was obtained during 24-h pH-impedance monitoring. Heartburn severity was evaluated using the GERD-HRQL questionnaire. Before treatment, baseline impedance in GERD patients was lower than in healthy controls (p < 0.001). Antireflux therapy increased baseline impedance (from 1498 [IQR 951-2472] to 2393 [IQR 1353-3027] Ω, p = 0.001), however it only led to a partial recovery when compared to healthy controls (2393 [IQR 1353-3027] vs 2983 [2335-3810] Ω, p < 0.01). The effect of both treatment options was not significantly different (p = 0.13) despite the increased number of non-acid reflux events in the PPI group. No correlation was found between baseline impedance and GERD symptoms before or after treatment. Reduction in acid reflux by endoscopic fundoplication or PPI therapy leads to an increase in baseline impedance in GERD patients, likely to reflect recovery of mucosal integrity. The impact of non-acid reflux events on esophageal mucosal integrity may be limited as no difference in the increase in baseline impedance was observed after both treatment options. The lack of association between impedance baseline and heartburn severity indicates that other factors may contribute to heartburn perception in GERD. © 2014 John Wiley & Sons Ltd.

The purpose of this study was to examine psychosocial factors related to gastroesophageal reflux disease (GERD) and their effects on quality of life (QOL) in firefighters. Data were collected from 1217 firefighters in a Korean province. We measured psychological symptoms using the scale. In order to observe the influence of the high-risk group on occupational stress, we conduct logistic multiple linear regression. The correlation between psychological factors and QOL was also analyzed and performed a hierarchical regression analysis. GERD was observed in 32.2% of subjects. Subjects with GERD showed higher depressive symptom, anxiety and occupational stress scores, and lower self-esteem and QOL scores relative to those observed in GERD - negative subject. GERD risk was higher for the following occupational stress subcategories: job demand, lack of reward, interpersonal conflict, and occupational climate. The stepwise regression analysis showed that depressive symptoms, occupational stress, self-esteem, and anxiety were the best predictors of QOL. The results suggest that psychological and medical approaches should be combined in GERD assessment.

Transoral incisionless fundoplication (TIF) with the EsophyX™ device creates an antireflux valve with good functional results in patients with gastro-esophageal reflux disease (GERD). The aim of this study was to assess the long-term effect of TIF 2.0 on pathological reflux and symptoms in GERD patients with daily dependence on proton pump inhibitors (PPI). Fifty patients underwent TIF. All underwent GERD-HRQL and GERD-QUAL questionnaires, upper GI endoscopy, esophageal manometry, and 24-h pH-impedance before and 6, 12, and 24 months after TIF, and subsequent yearly clinical re-evaluation. Patients were followed for up to six years (mean 52.7 ± 19.7 months). In all, 83.7, 79.6, 87.8, and 84.4% of patients stopped or halved the PPI therapy 6, 12, 24, and 36 months after TIF. Three-year figure remained stable up to 6 years. Symptom scores off PPI were significantly lower at 6, 12, 24, and 36 months. At 6 months, Hill's grade I of the newly created valve persisted in all pre-procedure Hill's grade I patients, in 66.7% of grade II and 58.3% of grade III. This figure remained substantially unchanged at 12 and 24 months, too. Impedance monitoring indicated significantly fewer total and acid refluxes after treatment (p = 0.01). Factors predicting good outcomes were pre-procedure Hill's grade I-II, no hiatal hernia or hernia ≤2 cm (p = 0.03), absence of ineffective esophageal motility (p < 0.0001), and number of fasteners deployed (p = 0.01). TIF by the EsophyX achieved lasting elimination of daily dependence on PPI in 75-80% of patients for up to 6 years. TIF seems an effective therapy for selected symptomatic GERD patients.

The aim of this study was to explore determinants of residual reflux symptoms among patients with gastroesophageal reflux disease (GERD) despite maintenance treatment with acid suppressive medication (ASM). Primary care GERD patients on chronic ASM were classified as symptom-free (55%) or symptomatic (45%) according to the impact of their residual reflux symptoms (QolRad). They were compared with respect to lifestyle (BMI, alcohol, smoking, physical exercise), compliance (daily ASM dosage), disease history, psychological factors (SCL-90) and quality of life (SF-36). None of the investigated lifestyle factors, nor dosage and disease history were related to residual symptoms. However, symptomatic patients differed from patients with relief on all psychological and quality of life dimensions. In a multiple logistic regression model somatization, hostility, mental health, body pain, as well as gender were independently associated with residual symptoms; the derived ROC curve had an AUC of 0.78. The majority of GERD patients is symptom-free on chronic ASM; they display a healthy psychological state and high quality of life. Residual symptoms however, are associated with psychological distress and lower quality of life. Recognition of this subgroup might hold the key to improving long-term management of gastroesophageal reflux. Copyright 2008 S. Karger AG, Basel.

Is the advanced age a contraindication to GERD laparoscopic surgery? Results of a long term follow-up

PubMed Central

2013-01-01

Background In this prospective non randomized observational cohort study we have evaluated the influence of age on outcome of laparoscopic total fundoplication for GERD. Methods Six hundred and twenty consecutive patients underwent total laparoscopic fundoplication for GERD. Five hundred and twenty-four patients were younger than 65 years (YG), and 96 patients were 65 years or older (EG). The following parameters were considered in the preoperative and postoperative evaluation: presence, duration, and severity of GERD symptoms, presence of a hiatal hernia, manometric and 24 hour pH-monitoring data, duration of operation, incidence of complications and length of hospital stay. Results Elderly patients more often had atypical symptoms of GERD and at manometric evaluation had a higher rate of impaired esophageal peristalsis in comparison with younger patients. The duration of the operation was similar between the two groups. The incidence of intraoperative and postoperative complications was low and the difference was not statistically significant between the two groups. An excellent outcome was observed in 93.0% of young patients and in 88.9% of elderly patients (p = NS). Conclusions Laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients, warranting low morbidity and mortality rates and a significant improvement of symptoms comparable to younger patients.

A cross-sectional study was carried out at Shifa International Hospital Islamabad over a period of 6 months, to determine the frequency and compare the different lifestyle modifications among patients with Gastroesophageal Reflux Disease (GERD) of different monthly income groups. Two hundred patients of GERD were enrolled in the study and divided into two groups based on monthly income less than and more than Rs. 30,000 respectively. Data was analyzed using SPSS 21. Descriptive statistics were calculated. Chi-square test was applied keeping p-value <0.05. Mean age was 40±13 years, 82 (41%) males and 118 (59%) females. Walking was undertaken by 32% after meals and 87.5% consumed tea. Significant difference was seen between income groups and higher intake of fried and spicy foods respectively. Thus, effort needs to be made in creating awareness and counseling patients to practice lifestyle modifications to reduce GERD symptoms and stop sole reliance on medications.

Despite the increasing role of mobile applications (apps) in patient education, there has been little inquiry evaluating the quality of these resources. Because poor health literacy has been associated with inferior health outcomes, evaluating the quality of patient education materials takes on great importance. Our objective was to employ validated readability tools for the evaluation of gastroesophageal reflux (GERD) mobile apps. GERD-specific apps found in the Apple App Store (Apple Inc., Cupertino CA) were evaluated using the Readability Studio Professional Version 2015 for Windows (Oleander Software, Ltd, Vandalia, OH). All text was evaluated using nine validated algorithms measuring readability including Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook grading, Gunning Fog index, Coleman-Liau, New Fog Count formula, Raygor Readability Estimate, FORCAST, Fry graph, and Flesch Reading Ease score. Average reading grade levels for individual GERD apps ranged from 9.6 to 12.9 (interquartile range 10.3-12). The average reading grade level for all apps analyzed was 11.1 ± 0.2 standard error of the mean (SEM), with an average Flesch Reading Ease score for all mobile apps analyzed of 51 ± 2.05 (SEM), falling into the "fairly difficult" category given by this measure. Raygor Readability estimates that most mobile apps have a reading grade level between 10 and 12, with the majority of this outcome due to long words. This analysis demonstrates the feasibility of assessing readability of mobile health apps. Our findings suggest significant gaps in potential comprehension between the apps analyzed and the average reader, diminishing the utility of these resources. We hope our findings influence future mobile health-related app development and thereby improve patient outcomes in GERD and other chronic diseases. NA.

The diagnosis of gastro-oesophageal reflux disease (GERD) in clinical practice is limited by the sensitivity and specificity of symptoms and diagnostic testing. To determine if adding histology as a criterion and excluding patients with epigastric pain enhances the diagnosis for GERD. Patients with frequent upper gastrointestinal symptoms who had not taken a proton pump inhibitor in the previous 2 months and who had evaluable distal oesophageal biopsies were included (Diamond study: NCT00291746). Epithelial hyperplasia was identified when total epithelial thickness was at least 430 μm. Investigation-based GERD criteria were: presence of erosive oesophagitis, pathological oesophageal acid exposure and/or positive symptom-acid association probability. Symptoms were assessed using the Reflux Disease Questionnaire and a pre-specified checklist. Overall, 127 (55%) of the 231 included patients met investigation-based GERD criteria and 195 (84%) met symptom-based criteria. Epithelial hyperplasia was present in 89 individuals, of whom 61 (69%) met investigation-based criteria and 83 (93%) met symptom-based criteria. Adding epithelial hyperplasia as a criterion increased the number of patients diagnosed with GERD on investigation by 28 [12%; number needed to diagnose (NND): 8], to 155 (67%). The proportion of patients with a symptom-based GERD diagnosis who met investigation-based criteria including epithelial hyperplasia was significantly greater when concomitant epigastric pain was absent than when it was present (P < 0.05; NND: 8). Histology increases diagnosis of GERD and should be performed when clinical suspicion is high and endoscopy is negative. Excluding patients with epigastric pain enhances sensitivity for the diagnosis of GERD. © 2017 John Wiley & Sons Ltd.

The objective of this study was to examine the relationship of work loss associated with gastro- the relationship of work loss associated with gastro- the relationship of work loss associated with gastro-esophageal reflux disease (GERD) and peptic ulcer disease (GERD) and peptic ulcer disease (PUD) in a large population of employed individuals in the United States (US) and quantify the individuals in the United States (US) and quantify the economic impact of these diseases to the employer. A proprietary database that contained work place absence, disability and workers' compensation data in addition to prescription drug and medical claims was used to answer the objectives. Employees with a medical claim with an ICD-9 code for GERD or PUD were identified from 1 January 1997 to 31 December 2000. A cohort of controls was identified for the same time period using the method of frequency matching on age, gender, industry type, occupational status, and employment status. Work absence rates and health care costs were compared between the groups after adjusting for demo graphic, and employment differences using analysis of covariance models. There were significantly lower (p < 0.05) prescription, and outpatient costs in the controls compared to the disease groups, although the eta-square values were very low. The mean work absence attributed to sick days was 2.8 (+/- 2.3) for controls, 3.4 (+/- 2.5) for GERD, 3.2 (+/- 2.6) for PUD, and 3.2 (+/- 2.3) days for GERD + PUD. For work loss, a significantly higher (p < 0.05) rate of adjusted all-cause absenteeism and sickness-related absenteeism were observed between the disease groups versus the controls. In particular, controls had an average of 1.2 to 1.6 days and 0.4 to 0.6 lower all-cause and sickness-related absenteeism compared to the disease groups. The incremental economic impact projected to a hypothetical employed population was estimated to be $3441 for GERD, $1374 for PUD, and $4803 for GERD + PUD per employee per

Respiratory manifestations of gastroesophageal reflux disease (GERD), particularly chronic cough, are being recognized with increased frequency in children. This survey aimed to investigate the efficacy of laparoscopic Nissen fundoplication for treatment of GERD-related respiratory symptoms not responsive to medical therapy in neurological normal children. We collected data of children with GERD-related respiratory complaints not responsive to medical therapy who underwent laparoscopic Nissen fundoplication in four European centers of Pediatric Surgery over a 10-year period. We excluded children with neurological impairment. A total of 220 laparoscopic Nissen procedures were performed in the period 2005-2015. Twenty-four (12 boys and 12 girls, average age 9.5 years) out of the 220 patients (10.9%) presented with chronic cough and other respiratory manifestations, including asthma, reactive airway disease, and recurrent pneumonia. Average operative time was 65 minutes (range 45-100). As for postoperative complications, two tight wraps requiring endoscopic dilatation (IIIb Clavien) and two relapses of GERD for slipped Nissen requiring reoperation (IIIb Clavien) were recorded. None of these complications occurred in the group of patients with GERD-related respiratory symptoms. At follow-up evaluation, respiratory symptoms disappeared with a significant improvement of quality of life scoring (I Grade Visick) in 22/24 patients (91.6%). Our results confirm that GERD should be investigated as one of the possible etiologic factors in any child with persistent respiratory complaints. In patients with symptoms not responsive to medical therapy, laparoscopic Nissen fundoplication is the treatment of choice with a very high success rate (>90% in our series), a very low morbidity, a significant improvement in airway symptoms, and a marked reduction in the need for medications.

Patients with gastroesophageal reflux disease (GERD) are routinely prescribed one of the six FDA approved proton pump inhibitors (PPI). All of these PPI are inhibitors of CYP2C19 enzyme to varying degrees. The phenotype pantoprazole- 13 C breath test (Ptz-BT) was used to identify patients who are poor metabolizers (PM) and the extent of phenoconversion of CYP2C19 enzyme activity caused by four PPI (omeprazole, esomprazole pantoprazole and rabeprazole) in 54 newly diagnosed GERD patients prior to initiating randomly selected PPI therapy and 30 d after PPI therapy. The phenoconversion after 30 d of PPI therapy in GERD patients was statistically significant (p  =0.001) with omeprazole/esomeprazole (n  =  27) strong CYP2C19 inhibitors, while there was no change in CYP2C19 enzyme activity (p  =  0.8) with pantoprazole/ rabeprazole (n  =  27), weak CYP2C19 inhibitors. The concommitant use of omeprazole/esomeprazole, therefore, could have critical clinical relevance in individualizing medications metabolized primarily by CYP2C19 such as PPI, clopidogrel, phenytoin, cyclophosphamide, thalidomide, citalopram, clonazepam, diazepam, proguanil, tivantinib etc. The rapid (30 min), in vivo, and non-invasive phenotype Ptz-BT can evaluate CYP2C19 enzyme activity. More importantly, it can identify GERD patients with low CYP2C19 enzyme activity (PM), caused by PPI or other concomitant medications, who would benefit from dose adjustments to maintain efficacy and avoid toxicity. The existing CYP2C19 genotype tests cannot predict the phenotype nor can it detect phenoconversion due to non genetic factors.

Background/Aims The occurrence of gastroesophageal reflux disease (GERD) is known to be associated with lower post-treatment lower esophageal sphincter pressure in patients with achalasia. This study aimed to elucidate whether GERD after pneumatic balloon dilatation (PD) has a prognostic role and to investigate how the clinical course of GERD is. Methods A total of 79 consecutive patients who were first diagnosed with primary achalasia and underwent PD as an initial treatment were included in this retrospective study. Single PD was performed using a 3.0 cm balloon. The patients were divided into two groups: 1) who developed GERD after PD (GERD group) and 2) who did not develop GERD after PD (non-GERD group). GERD was defined as pathological acid exposure, reflux esophagitis or typical reflux symptoms. Results Twenty one patients (26.6%) developed GERD after PD during follow-up. There were no significant differences between the two groups in demographic or clinical factors including pre- and post-treatment manometric results. All patients in GERD group were well responsive to maintenance proton pump inhibitor therapy including on demand therapy or did not require maintenance. During a median follow-up of 17.8 months (interquartile range, 7.1–42.7 months), achalasia recurred in 15 patients (19.0%). However, the incidence of recurrence did not differ according to the occurrence of GERD after PD. Conclusions GERD often occurs after even a single PD for achalasia. However, GERD after PD is well responsive to PPI therapy. Our data suggest that GERD after PD during follow-up does not appear to have a prognostic role. PMID:24840373

Accounting for the effect of GERD symptoms on patients' health-related quality of life: supporting optimal disease management by primary care physicians.

To review, from a primary care physician (PCP) perspective, the use of patient-reported outcome (PRO) instruments for assessment of gastro-oesophageal reflux disease (GERD) symptoms, their impact on health-related quality of life (HRQL) and the effectiveness of therapy. While generic and disease-specific PRO instruments have been used in the assessment of GERD, the latter can be considered to be more appropriate as they focus only on problems relevant to the disease in question (and therefore tend to be more responsive to change). Such instruments include the Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaire and the Gastrointestinal Symptom Rating Scale and the Reflux Disease Questionnaire (RDQ). Their use indicates that GERD symptoms are troublesome and significantly reduce patients' HRQL, and that effective treatment of GERD improves HRQL. The GERD Impact Scale (GIS) questionnaire, primarily developed for use within primary care, can also help to determine the impact of symptoms on patients' everyday lives and, in turn, the benefit of appropriately targeted therapy. Notably, these PRO instruments were developed from focus groups of GERD patients, and only aspects rated of highest importance are used in the final instruments. Consequently, PCPs can feel confident that these questionnaires encompass the most relevant points that they are likely to ask in terms of how symptoms affect patients' everyday lives. Primary care physicians are encouraged to make wider use of PRO instruments within routine practice to improve communication with their GERD patients that, in turn, could lead to improved clinical outcomes and greater patient satisfaction.

The attachment styles and parental bonding by 64 patients (M age = 43.2 yr., SD = 13.3) with Gastroesophageal Reflux Disease (GERD) were compared with those of 64 patients (M age = 42.2 yr., SD = 13.5) with Inflammatory Bowel Disease (IBD) and 126 Healthy participants (M age = 42.2 yr., SD = 12.1). Analysis of scores on the Attachment Style Questionnaire indicated insecure attachment in both the patient and control groups. The Parental Bonding scores indicated perceptions of Affectionless Control by parents in both patient groups. In particular, the mean Father-Protection subscale scores were significantly higher for in the GERD group than in the Healthy and IBD groups.

The aim of this study was to estimate the heritability (h2) and genetic correlation (ρG) between GERD symptoms severity, metabolic syndrome components, and inflammation markers in Mexican families. Cross-sectional study which included 32 extended families resident in Mexico City. GERD symptoms severity was assessed by the ReQuest in Practice questionnaire. Heritability and genetic correlation were determined using the Sequential Oligogenic Linkage Analysis Routines software. 585 subjects were included, the mean age was 42 (±16.7) years, 57% were women. The heritability of the severity of some GERD symptoms was h2 = 0.27, 0.27, 0.37, and 0.34 (p-value <1.0x10-5) for acidity complaints, lower abdominal complaints, sleep disturbances, and total ReQuest score, respectively. Heritability of metabolic syndrome components ranged from 0.40 for fasting plasma glucose to 0.61 for body mass index and diabetes mellitus. The heritability for fibrinogen and C-reactive protein was 0.64 and 0.38, respectively. Statistically significant genetic correlations were found between acidity complaints and fasting plasma glucose (ρG = 0.40); sleep disturbances and fasting plasma glucose (ρG = 0.36); acidity complaints and diabetes mellitus (ρG = 0.49) and between total ReQuest score and fasting plasma glucose (ρG = 0.43). The rest of metabolic syndrome components did not correlate with GERD symptoms. Genetic factors substantially explain the phenotypic variance of the severity of some GERD symptoms, metabolic syndrome components and inflammation markers. Observed genetic correlations suggest that these phenotypes share common genes. These findings suggest conducting further investigation, as the determination of a linkage analysis in order to identify regions of susceptibility for developing of GERD and metabolic syndrome.

Chest pain experienced by patients with coronary artery disease can be partly due to gastroesophageal reflux-induced chest pain (GERP). Empirical proton pump inhibitor (PPI) therapy has been recommended as an initial clinical approach for treating GERP. However, PPI use may lead to some health problems. The Gastroesophageal Reflux Disease Questionnaire (GerdQ) may represent a noninvasive and cost-effective approach for avoiding PPI misuse and for identifying the appropriate patients for the PPI trial test. The aim of this pilot study was to prospectively evaluate the association between GerdQ scores and PPI response in patients with coronary artery disease (CAD) and GERP to determine whether the GerdQ predicts the PPI response in patients with CAD and GERP and to further validate the clinical application value of the GerdQ. A total of 154 consecutive patients with potential GERP were recruited to complete a GerdQ with subsequent PPI therapy. Based on the PPI trial result, patients were divided into a PPI-positive response group and a PPI-negative response group. The difference in the GerdQ scores between the two groups was assessed. The receiver operating characteristic (ROC) curve of GerdQ score was drawn according to the PPI response as the gold standard. The ability of GerdQ to predict the PPI response was assessed. A total of 96 patients completed the entire study; 62 patients (64.6%) were assigned to the PPI-positive response group, and 34 patients (35.4%) to the PPI-negative response group. The GerdQ score of the PPI-positive response group (8.11 ± 3.315) was significantly higher than that of the PPI-negative response group (4.41 ± 2.743), and the difference was statistically significant (t = 5.863, P = 0.000). The ROC curve was drawn according to a PPI response assessment result with a score above 2 as the gold standard. The area under curve was 0.806. When the critical value of GerdQ score was 7.5, Youden index was up to 0.514, the diagnostic sensitivity

Look--but also listen! ReQuest: A new dimension-oriented GERD symptom scale.

PubMed

The symptom spectrum of gastroesophageal reflux disease (GERD) is much wider than is commonly believed, and in about half the patients endoscopic examination is negative. The role of endoscopy to assess response to treatment is therefore much reduced in GERD. Assessment of symptoms is becoming increasingly important, so different outcome measures are required. The Reflux Questionnaire ReQuest was thus designed as a brief, effective and robust method of tracking and quantifying GERD symptoms during treatment. It comprises seven dimensions: general well-being, acid complaints, upper abdominal/stomach complaints, lower abdominal/digestive complaints, nausea, sleep disturbances and other complaints. In the short version of ReQuest the symptom burden of each dimension is measured by its frequency and intensity (except general well-being, for which only the intensity was determined). The long version also includes 67 symptom descriptions that constitute the dimensions (except general well-being). The rigorous validation process included clinical trial evaluation and statistical assessment of the findings. Important measures of the instrument, such as internal consistency, test/ retest reliability, construct validity and the responsiveness to changes during treatment, among others, all fulfilled or exceeded requirements, thereby demonstrating the accuracy of the instrument. ReQuest meets the criteria set by regulatory authorities and serves as the primary outcome measure for symptom assessment in future clinical trials of current and new treatments.

Gastroesophageal reflux disease (GERD) is recognized as one of the most common disorders of the upper gastrointestinal tract (GIT). The best choice of management for advanced GERD is laparoscopic surgery. To compare and evaluate the results of surgical treatment of GERD patients operated on using two different techniques. Between 2001 and 2012, 353 patients (211 female and 142 male), aged 17-76 years (mean 44), underwent laparoscopic antireflux surgery. The study included patients who underwent a Toupet fundoplication or Wroblewski Tadeusz procedure (WTP). The mean age of the group was 47.77 years (17-80 years). Forty-nine (32.45%) patients had severe symptoms, 93 (61.58%) had mild symptoms and 9 (5.96%) had a single mild but intolerable sign of GERD. Eighty-six (56.95%) patients had a Toupet fundoplication and 65 (43.04%) had a WTP. The follow-up period was 18-144 months. The average operating time for Toupet fundoplication and the WTP procedure was 164 min (90-300 min) and 147 min (90-210 min), respectively. The perioperative mortality rate was 0.66%. The average post-operative hospitalization period was 5.4 days (2-16 post-operative days (POD) = Toupet) vs. 4.7 days (2-9 POD = WTP). No reoperations were performed. No major surgical complications were identified. Wroblewski Tadeusz procedure due to a low percentage of post-operative complications, good quality of life of patients and a zero recurrence rate of hiatal hernia should be a method of choice.

To assess the accuracy of pathology reports on gallbladder specimens from patients operated on for incidental gallbladder carcinoma. Demographic data, details on pathological reports including gross and microscopic features section were recorded in 100 selected patients with incidental gallbladder carcinoma diagnosed from 2004 to 2007. Pathology reports had a conventional format in 93% of cases, without any standardization. Turnaround time ranged from 1 to 35 days. Frozen sections were performed in 20% of cases. The reports failed to give information on prognostic histological factors: exact tumour site (missing in 55% of cases), depth of tumour infiltration within the gallbladder wall (missing in 10%), surgical margins (missing in 40% for the cystic duct margin), tumour differentiation (missing in 28%), vascular invasion (missing in 52%) and perineural invasion (missing in 51%). Lymph node status could be assessed in 44% of cases. Distances between the tumour and the cystic duct and circumferential margins were not specified in 68% and 84% of cases. Only 29% of the reports clearly stated the pTNM stage in the conclusion section. The pT stage with margin status and tumour site was only mentioned in 30% of the reports. Pathology reports on gallbladder carcinoma from participating centres frequently lacked important information on key prognostic histological factors.

The Use of Visual Arts as a Window to Diagnosing Medical Pathologies.

Observation is a key step preceding diagnosis, prognostication, and treatment. Careful patient observation is a skill that is learned but rarely explicitly taught. Furthermore, proper clinical observation requires more than a glance; it requires attention to detail. In medical school, the art of learning to look can be taught using the medical humanities and especially visual arts such as paintings and film. Research shows that such training improves not only observation skills but also teamwork, listening skills, and reflective and analytical thinking. Overall, the use of visual arts in medical school curricula can build visual literacy: the capacity to identify and analyze facial features, emotions, and general bodily presentations, including contextual features such as clothing, hair, and body art. With the ability to formulate and convey a detailed "picture" of the patient, clinicians can integrate aesthetic and clinical knowledge, helping facilitate the diagnosing of medical pathologies. © 2016 American Medical Association.

Dental neglect and high levels of unmet dental needs are becoming increasingly prevalent among elderly residents of long-term care facilities, although frail, elderly, and dependent populations are the most in need of professional dental care. Little is known about the validity of teledentistry for diagnosing dental pathology in nursing home residents. To evaluate the accuracy of teledentistry for diagnosing dental pathology, assessing the rehabilitation status of dental prostheses, and evaluating the chewing ability of older adults living in nursing homes (using direct examination as a gold standard). Multicenter diagnostic accuracy study performed in France and Germany. Eight nursing homes in France and Germany. Nursing home residents with oral or dental complaints, self-reported or reported by caregivers, willing to receive oral or dental preventive care. In total, 235 patients were examined. The mean age was 84.4 ± 8.3 years, and 59.1% of the subjects were female. The patients were examined twice. Each patient was his or her own control. First, the dental surgeon established a diagnosis by reviewing a video recorded in the nursing home and accessed remotely. Second, within a maximum of 7 days, patients were examined conventionally (face-to-face) by the same surgeon who established the initial diagnosis. All residents received a comprehensive clinical examination in their home by a trained geriatrician and underwent a dental hygiene evaluation that used the Silness-Loe and Greene-Vermillion dental hygiene assessment indices. The diagnoses established via the video recording and in the face-to-face setting were compared. The main outcome measure was number of dental pathologies. In total, 128 (55.4%) patients had a dental pathology. The sensitivity of teledentistry for diagnosing dental pathology was 93.8% (95% confidence interval [CI] 90.7-96.9), and the specificity was 94.2% (95% CI 91.2-97.2).

We describe the National Registry for Fetal Cardiac Pathology, a program under the Polish Ministry of Health aimed at improving the prenatal diagnosis, care, and management of congenital heart disease (CHD). An online database was created to prospectively record diagnosis, prenatal care, delivery, follow-up, and still images and video for fetuses with CHD. A certification program in fetal cardiac ultrasound was also implemented. Optimal screening and referral centers were identified by number of fetuses entered in the Registry yearly by each center. From 2004 to 2009, 2910 fetuses with CHD were registered (2473 structural, 437 functional anomalies). The most common reasons for referral for fetal echocardiography were abnormal four-chamber view (56.0%) and extra-cardiac anomalies (8.2% ), while the most common diagnoses were atrioventricular septal defects (10.2%) and hypoplastic left heart syndrome (9.7%). Prenatal diagnosis increased yearly, from 10.0% of neonatal diagnoses in 2003 to 38.0% in 2008. From inception of the registry up to 2009 there has been a fourfold increase in the number of neonates referred for cardiac surgery in whom the condition was prenatally diagnosed. Equally important achievements include the establishment of a certification program for fetal echocardiography and the organization of prenatal and neonatal management. © 2012 John Wiley & Sons, Ltd.

Disease burden and associated costs are not well understood among patients with gastroesophageal reflux disease (GERD) who have persistent symptoms despite optimized proton pump inhibitor (PPI) therapy. The aim of this study was to investigate disease burden and costs of GERD in partial responders to PPI therapy. The Partial Response to PPI treatment: the Cost to Society and the Burden to the Patient in the US (REMAIN US) study was a 12-month, multicenter, noninterventional, observational study of 552 partial PPI responders in the USA. Participating sites were comprised of family practice (n = 30), internal medicine (n = 8), and specialist (gastroenterologist) centers (n = 15). GERD symptoms, health-related quality of life (HRQL), and impact on productivity were evaluated from patient-reported outcome instruments. Resource utilization data were also collected. Patients had a high symptom burden, impaired HRQL, and reduced productivity while at work and in daily activities, despite optimized PPI therapy. Mean annual GERD-related costs were US$9944 per patient, comprising total direct costs and mean productivity loss costs of US$4068 and US$5876 per patient, respectively. Patients with GERD and a partial response to PPI therapy have considerable direct and indirect costs, along with substantial impairments in HRQL and productivity.

This study is to determine the association of ambulatory pH monitoring (24hr pH) with symptoms of gastroesophageal reflux and its other investigations. The clinical and epidemiological profiles of subjects referred for reflux disorders are also studied. Symptoms or group of symptoms, profiles and prior investigations of 1259 consecutive pediatric subjects (with 1332 24hr pH studies performed) referred for evaluation of reflux disorders between 1988 and 2012 were retrospectively studied. Chi-square or fisher exact test was used for hypothesis testing, student t-test for the comparison of means and the Wilcoxon rank-sum test for comparing medians of continuous variables. Gastroesophageal reflux disease (GERD), defined as reflux causing major symptoms and complications, was diagnosed in 57.5% subjects of the total sample. Forty-three percent were girls and 56.7% were boys. The most common age group was between 4 months and 2 years (51.2%). Vomiting (64.4%) and irritability (74%) were the most common symptoms with the neurological conditions (23.2%) being the most frequent underlying condition. The parameters used in 24hr pH were significantly higher in those diagnosed with GERD (P < 0.0001). The prevalence of GERD was found to be significantly higher when both gastrointestinal and respiratory symptoms were present (P = 0.008) at 66.4% than when compared with gastrointestinal (56.5%) and respiratory (52.2%) symptoms in isolation. Symptoms alone were not reliable in diagnosing GERD. Only 57.5% had GERD among patients referred for reflux disorders. 24hr pH is reliable and should be considered routine in reflux disorders, as it identifies patients with pathologic reflux and avoids a needless surgery. © 2016 International Society for Diseases of the Esophagus.

Impact of transoral incisionless fundoplication (TIF) on subjective and objective GERD indices: a systematic review of the published literature.

Wendling, Mark R; Melvin, W Scott; Perry, Kyle A

2013-10-01

Gastroesophageal reflux disease (GERD) remains a significant problem for the medical community. Many endoluminal treatments for GERD have been developed with little success. Currently, transoral incisionless fundoplication (TIF) attempts to recreate a surgical fundoplication through placement of full-thickness polypropylene H-fasteners. This, the most recent procedure to gain FDA approval, has shown some promise in the early data. However, questions of its safety profile, efficacy, and durability remain. The Cochrane Library and MEDLINE through PubMed were searched to identify published studies reporting on subjective and objective GERD indices after TIF. The search was limited to human studies published in English from 2006 up to March 2012. Data collected included GERD-HRQL and RSI scores, PPI discontinuation and patient satisfaction rates, pH study metrics, complications, and treatment failures. Statistical analysis was performed with weighted t tests. Titles and abstracts of 214 papers were initially reviewed. Fifteen studies were found to be eligible, reporting on over 550 procedures. Both GERD-HRQL scores (21.9 vs. 5.9, p < 0.0001) and RSI scores (24.5 vs. 5.4, p ≤ 0.0001) were significantly reduced after TIF. Overall patient satisfaction was 72 %. The overall rate of PPI discontinuation was 67 % across all studies, with a mean follow-up of 8.3 months. pH metrics were not consistently normalized. The major complication rate was 3.2 % and the failure rate was 7.2 % across all studies. TIF appears to provide symptomatic relief with reasonable levels of patient satisfaction at short-term follow-up. A well-designed prospective clinical trial is needed to assess the effectiveness and durability of TIF as well as to identify the patient population that will benefit from this procedure.

Endoluminal therapies have emerged as adjuncts for the treatment of gastroesophageal reflux disease (GERD) in select patients. To compare the effectiveness of endoscopic full-thickness plication and endoscopic radiofrequency treatments for patients with GERD. A total of 126 patients who underwent either endoscopic full-thickness plication (FTP) of the gastric cardia or endoscopic radiofrequency (RF) treatment of the esophagogastric junction during a 4-year period were included (68 underwent RF and 58 underwent FTP). Follow-up data was obtained for 51% of patients (mean follow-up, 6 months). Comparison of medication use, symptom scores, and pH values at baseline and follow-up. In the RF group, patients with moderate to severe heartburn decreased from 55% to 22% (P < .01), and proton pump inhibitor (PPI) use decreased from 84% to 50% (P = .01). Decreases were also seen for dysphagia, voice symptoms, and cough. Percentage of time the pH was less than 4 was unchanged. In the FTP group, patients with moderate to severe heartburn decreased from 53% to 43% (P = .3), and PPI use decreased from 95% to 43% (P = .01). Percentage of time the pH was less than 4 decreased from 10.0% to 6.1% (P = .05). Decreases were also seen for regurgitation, voice symptoms, and dysphagia. There was no change in scores for chest pain or asthma in either group. For patients with GERD, RF and FTP both resulted in a decrease in both PPI use and in scores for voice symptoms and dysphagia. In addition, RF resulted in decreased heartburn and cough, while FTP resulted in the most dramatic reduction in regurgitation. Our experience indicates that both procedures are effective, providing symptomatic relief and reduction in PPI use. For patients whose chief complaint is regurgitation, FTP may be the preferred procedure.

Recently, an 'acid pocket' has been described in the proximal stomach, particularly evident postprandially in GERD patients, when heartburn is common. By creating a low density gel 'raft' that floats on top of gastric contents, alginate-antacid formulations may neutralise the 'acid pocket'. To assess the ability of a commercial high-concentration alginate-antacid formulation to neutralize and/or displace the acid pocket in GERD patients. The 'acid pocket' was studied in ten symptomatic GERD patients. Measurements were made using concurrent stepwise pH pull-throughs, high resolution manometry and fluoroscopy in a semi-recumbent posture. Each subject was studied in three conditions: fasted, 20 min after consuming a high-fat meal and 20 min later after a 20 mL oral dose of an alginate-antacid formulation (Gaviscon Double Action Liquid, Reckitt Benckiser Healthcare, Hull, UK). The relative position of pH transition points (pH >4) to the EGJ high-pressure zone was analysed. Most patients (8/10) exhibited an acidified segment extending from the proximal stomach into the EGJ when fasted that persisted postprandially. Gaviscon neutralised the acidified segment in six of the eight subjects shifting the pH transition point significantly away from the EGJ. The length and pressure of the EGJ high-pressure zone were minimally affected. Gaviscon can eliminate or displace the 'acid pocket' in GERD patients. Considering that EGJ length was unchanged throughout, this effect was likely attributable to the alginate 'raft' displacing gastric contents away from the EGJ. These findings suggest the alginate-antacid formulation to be an appropriately targeted postprandial GERD therapy. © 2011 Blackwell Publishing Ltd.

The efficacy of transoral incisionless fundoplication (TIF) performed with the EsophyX device (Redmond, Washington, USA) and its long-term outcomes in gastresophageal reflux disease (GERD) are debated. We, therefore, performed a systematic review with meta-analysis of studies evaluating the role of TIF in GERD. A systematic search of EMBASE, SCOPUS, PubMed, and the Cochrane Library Central was performed. All original studies reporting outcomes in GERD patients who underwent TIF were identified. Only randomized controlled trials (RCTs) evaluating the efficacy of TIF, and prospective observational studies reporting outcomes after TIF were included. A total of 18 studies (963 patients) published between 2007 and 2015 were identified, including five RCTs and 13 prospective observational studies. The pooled relative risk of response rate to TIF versus PPIs/sham was 2.44 (95 % CI 1.25-4.79, p = 0.0009) in RCTs in the intention-to-treat analysis. The total number of refluxes was reduced after TIF compared with the PPIs/sham group. The esophageal acid exposure time and acid reflux episodes after TIF were not significantly improved. Proton-pump inhibitors (PPIs) usage increased with time and most of the patients resumed PPIs treatment at reduced dosage during the long-term follow-up. The total satisfaction rate after TIF was about 69.15 % in 6 months. The incidence of severe adverse events consisting of gastrointestinal perforation and bleeding was 2.4 %. TIF is an alternative intervention in controlling GERD-related symptoms with comparable short-term patient satisfaction. Long-term results showed decreased efficacy with time. Patients often resume PPIs at reduced doses in the near future.

There is a paucity of large-scale studies evaluating the clinical benefit of the Gaviscon Double Action (DA) alginate-antacid formulation for treating gastroesophageal reflux disease (GERD) symptoms. Randomised double-blind placebo-controlled parallel-group study to evaluate efficacy and safety of Gaviscon DA in reducing heartburn, regurgitation and dyspepsia symptoms in individuals with mild-to-moderate GERD in China. Participants with symptomatic GERD (n = 1107) were randomised to receive Gaviscon DA or placebo (two tablets four times daily) for seven consecutive days. The primary endpoint compared the change in Reflux Disease Questionnaire (RDQ) score for the GERD (heartburn + regurgitation) dimension between Gaviscon DA and placebo. Secondary endpoints compared the change in RDQ scores for individual heartburn, regurgitation and dyspepsia dimensions, overall treatment evaluation (OTE) scores and incidence of adverse events (AEs). Mean RDQ GERD scores: 2.51 for Gaviscon DA and 2.50 for placebo at baseline; 1.25 for Gaviscon DA and 1.46 for placebo post treatment. Gaviscon DA was statistically superior to placebo in reducing GERD and dyspepsia RDQ scores [least-squares mean (LSM) difference: GERD -0.21, P < 0.0001; dyspepsia -0.18, P = 0.0004], despite a substantial placebo response. The Gaviscon DA group reported more favourable overall treatment responses than the placebo group across all OTE categories (P < 0.0001). Superior relief of GERD symptoms was observed both in those with non-erosive and those with erosive reflux disease (LSM difference -0.14 [P = 0.038] and -0.29 [P < 0.0001] respectively). Incidence of AEs was similar in both groups. Gaviscon DA tablets provide effective and safe reduction in acid reflux and dyspepsia symptoms in Chinese individuals with mild-to-moderate GERD.

Referral for a second opinion is an important aspect of pathology practice, which reduces the rate of diagnostic error and ensures consistency with diagnoses. The Oral Pathology Centre (OPC) is the only specialist oral diagnostic centre in New Zealand. OPC provides diagnostic services to dentists and dental specialists throughout New Zealand and acts as a referral centre for second opinions for oral pathology specimens that have been sent to anatomical pathologists. The aim of this study was to review second opinion referral cases sent to the OPC over a 15-year period and to assess the levels of concordance between the original and final diagnoses. The findings indicated that the majority of referred cases were odontogenic lesions, followed by connective tissue, epithelial and salivary lesions. The most prevalent diagnoses were ameloblastoma and keratocystic odontogenic tumour, followed by oral squamous cell carcinoma. Discordant diagnoses were recorded in 24% of cases. Diagnostic discrepancies were higher in odontogenic and salivary gland lesions, resulting in the change of diagnoses. Second opinion of oral pathology cases should be encouraged in view of the relative rarity of these lesions in general pathology laboratories and the rates of diagnostic discrepancy, particularly for odontogenic and salivary gland lesions.

Although proton pump inhibitors (PPI) have a record of remarkable effectiveness and safety in the management of gastroesophageal reflux disease (GERD), several treatment challenges with PPI have emerged. Dexlansoprazole MR is the (R)-enantiomer of lansoprazole contained in a formulation that produces two distinct releases of drug and significantly extends the duration of active plasma concentrations and % time pH > 4 beyond that of conventional single-release PPI. Dexlansoprazole MR can be administered without regard to meals or the timing of meals in most patients. Dexlansoprazole MR 60 mg demonstrated similar efficacy for healing of erosive esophagitis at 8 weeks compared with lansoprazole 30 mg, and dexlansoprazole MR 30 mg was superior to placebo for maintenance of healed erosive esophagitis at 6 months with 99% of nights and 96% of days heartburn-free over 6 months in patients taking dexlansoprazole MR 30 mg. Superior relief of heartburn occurred in patients taking dexlansoprazole MR 30 mg (55% heartburn-free 24-hour periods) vs placebo (14%) for symptomatic nonerosive GERD. The safety profile of dexlansoprazole MR is similar to that of lansoprazole. The extended pharmacodynamic effects, added convenience, and efficacy and safety of dexlansoprazole MR offer a novel approach to gastric pH control in patients with acid-related disorders.

Objective: The purpose of this study was to examine the role of multiple pathologies in the expression of dementia in the oldest-old. Methods: A total of 183 participants of The 90+ Study with longitudinal follow-up and autopsy were included in this clinical-pathologic investigation. Eight pathologic diagnoses (Alzheimer disease [AD], microinfarcts, hippocampal sclerosis, macroinfarcts, Lewy body disease, cerebral amyloid angiopathy, white matter disease, and others) were dichotomized. We estimated the odds of dementia in relation to each individual pathologic diagnosis and to the total number of diagnoses. We also examined dementia severity in relation to number of pathologic diagnoses. Results: The presence of multiple pathologic diagnoses was common and occurred more frequently in those with dementia compared with those without dementia (45% vs 14%). Higher numbers of pathologic diagnoses were also associated with greater dementia severity. Participants with intermediate/high AD pathology alone were 3 times more likely to have dementia (odds ratio = 3.5), but those with single non-AD pathologies were 12 times more likely to have dementia (odds ratio = 12.4). When a second pathology was present, the likelihood of dementia increased 4-fold in those with intermediate/high AD pathology but did not change in those with non-AD pathologies, suggesting that pathologies may interrelate in different ways. Conclusions: In the oldest-old, the presence of multiple pathologies is associated with increased likelihood and severity of dementia. The effect of the individual pathologies may be additive or perhaps synergistic and requires further research. Multiple pathologies will need to be targeted to reduce the burden of dementia in the population. PMID:26180144

To evaluate the effects of transcranial direct current stimulation (tDCS) on esophageal peristalsis in patients with gastroesophageal reflux disease (GERD). Patients with GERD preliminary diagnosis were included in a randomized double-blind sham-controlled study. Esophageal manometry was performed before and during transcranial direct current stimulation (tDCS) of the right precentral cortex. Half of patients were randomly assigned to anodal, half to sham stimulation. Distal waves amplitude and pathological waves percentage were measured, after swallowing water boli, for ten subsequent times. Last, a 24h pH-bilimetry was done to diagnose non-erosive reflux disease (NERD) or functional heartburn (FH). The values obtained before and during anodal or sham tDCS were compared. Sixty-eight patients were enrolled in the study. Distal waves mean amplitude increased significantly only during anodal tDCS in NERD (p=0.00002) and FH subgroups (p=0.008) while percentage of pathological waves strongly decreased only in NERDs (p=0.002). Transcranial stimulation can influence cortical control of esophageal motility and improve pathological motor pattern in NERD and FH but not in erosive reflux disease (ERD) patients. Pathophysiological processes in GERD are not only due to peripheral damage but to central neural control involvement as well. In ERD patients dysfunctions of the cortico-esophageal circuit seem to be more severe and may affect central nervous system physiology.

Communication skills in diagnostic pathology.

2016-01-01

Communication is an essential element of good medical practice also in pathology. In contrast to technical or diagnostic skills, communication skills are not easy to define, teach, or assess. Rules almost do not exist. In this paper, which has a rather personal character and cannot be taken as a set of guidelines, important aspects of communication in pathology are explored. This includes what should be communicated to the pathologist on the pathology request form, communication between pathologists during internal (interpathologist) consultation, communication around frozen section diagnoses, modalities of communication of a final diagnosis, with whom and how critical and unexpected findings should be communicated, (in-)adequate routes of communication for pathology diagnoses, who will (or might) receive pathology reports, and what should be communicated and how in case of an error or a technical problem. An earlier more formal description of what the responsibilities are of a pathologist as communicator and as collaborator in a medical team is added in separate tables. The intention of the paper is to stimulate reflection and discussion rather than to formulate strict rules.

A causal relationship between cough and gastroesophageal reflux disease (GERD) has been established: a pro/con debate.

Along with upper airway cough syndrome (formerly, postnasal drip syndrome) and eosinophilic airway inflammation (asthma, nonasthmatic eosinophilic bronchitis), gastroesophageal reflux disease (GERD) is generally considered among the most common etiologies of chronic cough. Indeed, cough management guidelines published by numerous respiratory societies worldwide recommend evaluation and treatment of GERD as an integral component of the diagnostic/therapeutic algorithm for the management of chronic cough. However, a significant number of patients with chronic cough presumed due to GERD do not report improvement despite aggressive acid-suppressive therapy. Some of these refractory cases may be due to the recently appreciated entity of nonacid or weakly acidic reflux. Further contributing to the controversy are recent studies that demonstrate that patients with chronic cough do not have excessive reflux events relative to healthy volunteers. Although a temporal relationship between cough and reflux events has been suggested by studies utilizing impedance-pH monitoring of reflux events and objective cough recording, consensus is lacking in terms of whether this temporal relationship proves a causal link between reflux and cough. The fourth American Cough Conference (New York, June 2013) provided an ideal forum for the debate of this issue between two internationally recognized experts in the field of reflux and chronic cough.

Gastroesophageal reflux disease (GERD) can be difficult to diagnose - symptoms alone are often not enough, and thus, objective testing is often required. GERD is a manifestation of pathologic levels of reflux into the esophagus of acidic, nonacidic, and/or bilious gastric content. However, in our current evidence-based knowledge approach, we only have reasonable outcome data in regards to acid reflux, as this particular type of refluxate predictably causes symptoms and mucosal damage, which improves with medical or surgical therapy. While there are data suggesting that nonacid reflux may be responsible for ongoing symptoms despite acid suppression in some patients, outcome data about this issue are limited. Therefore, this working group believes that it is essential to confirm the presence of acid reflux in patients with 'refractory' GERD symptoms or extraesophageal symptoms thought to be caused by gastroesophageal reflux before an escalation of antireflux therapy is considered. If patients do not have pathologic acid reflux off antisecretory therapy, they are unlikely to have clinically significant nonacid or bile reflux. Patients who do not have pathologic acid gastroesophageal reflux parameters on ambulatory pH monitoring then: (i) could attempt to discontinue antisecretory medications like proton pump inhibitors and H2-receptor antagonists (which are expensive and which carry risks - i.e. C. diff, etc.); (ii) may undergo further evaluation for other causes of their esophageal symptoms (e.g. functional heartburn or chest pain, eosinophilic esophagitis, gastroparesis, achalasia, other esophageal motor disorders); and (iii) can be referred to an ear, nose, and throat/pulmonary/allergy physician for assessment of non-GERD causes of their extraesophageal symptoms. © 2012 Copyright the Authors.

In the era of mini invasive surgery, the surgical approach of the esogastric junction occupies an important role, which regards both the results and the complete, long-term patient satisfaction. The main benign pathology of the esogastric pole includes hiatal hernia, gastroesophageal reflux disease, cardiospasm, oesophageal diverticula. The present study is based on the experience of our clinic in the laparoscopic treatment of esogastric pathology that contains 85 patients in 10 years. Out of these, 15 were operated on for cardiospasm, 29 for hiatal hernia and 41 for gastroesophageal reflux disease (GERD). The investigation protocol consisted in barium swallows and endoscopy, both pre and postoperatively. The results obtained allowed us to underline the superiority of the surgical treatment over the medical one. Likewise, medical literature reports rates of success of 90% in antireflux surgery. The latter is conditioned by correct determination of the reflux causes and by the choice of the adequate time to perform the surgery, in concordance with the local anatomical conditions. As far as the two techniques used (complete or partial fundoplication) are concerned, there were no significant differences in the postoperative evolution of the patients, but we have to mention, nevertheless, the increased incidence of dysphagia after Nissen. The data presented confirm the superiority of laparoscopic surgery over the classic one, due to the superior aesthetic result, the shortened admission time –with reduced costs and rapid social reinsertion.

The ReQuest (Reflux Questionnaire) is a new instrument: a diary developed specifically to allow patients to measure the totality of their gastroesophageal reflux disease (GERD) symptoms and to track changes each day during treatment, an increasingly important need in clinical trials. This paper reviews the background, development, testing, and validation of the instrument and shows how its flexibility allows it to be used in new ways to assess different aspects of GERD. There were four key steps. (1) A full symptom spectrum was gathered from experts, literature and, crucially, from GERD patients, and comprised 67 symptom descriptions. (2) By expert consensus, these symptom descriptions were empirically condensed into six easier-to-handle 'dimensions' (acid complaints, upper abdominal/stomach complaints, lower abdominal/digestive complaints, nausea, sleep disturbances, other complaints), to which the seventh, general well-being, was added, a key feature of the instrument. The symptom burden of each dimension is measured as frequency x intensity (general well-being: intensity only). (3) This prototype instrument was tested in PPI clinical trials involving patients with erosive and non-erosive GERD, while the data generated were used to validate the prototype. (4) Finally, the scale was refined by factor analysis, a statistical process. Detailed statistical testing validating the scale and factor analysis confirmed that empirically condensing the symptom descriptions into dimensions did not affect the measurement properties of the instrument. FURTHER APPLICATION: The structure of ReQuest and its product, which is numerical, makes the instrument highly flexible and allows for its use in other GERD areas. (1) Its subscales, ReQuest-GI and ReQuest-WSO, measure symptoms traditionally associated with reflux and with general well-being, respectively, and permit these to be quantified and tracked independently.

Potential mechanism of corpus-predominant gastritis after PPI therapy in Helicobacter pylori-positive patients with GERD.

The long-term use of proton pump inhibitors (PPIs) exacerbates corpus atrophic gastritis in patients with Helicobacter pylori (H. pylori) infection. To identify a potential mechanism for this change, we discuss interactions between pH, bile acids, and H. pylori. Duodenogastric reflux, which includes bile, occurs in healthy individuals, and bile reflux is increased in patients with gastroesophageal reflux disease (GERD). Diluted human plasma and bile acids have been found to be significant chemoattractants and chemorepellents, respectively, for the bacillus H. pylori. Although only taurine conjugates, with a pKa of 1.8-1.9, are soluble in an acidic environment, glycine conjugates, with a pKa of 4.3-5.2, as well as taurine-conjugated bile acids are soluble in the presence of PPI therapy. Thus, the soluble bile acid concentrations in the gastric contents of patients with GERD after continuous PPI therapy are considerably higher than that in those with intact acid production. In the distal stomach, the high concentration of soluble bile acids is likely to act as a bactericide or chemorepellent for H. pylori. In contrast, the mucous layer in the proximal stomach has an optimal bile concentration that forms chemotactic gradients with plasma components required to direct H. pylori to the epithelial surface. H. pylori may then colonize in the stomach body rather than in the pyloric antrum, which may explain the occurrence of corpus-predominant gastritis after PPI therapy in H. pylori-positive patients with GERD.

AIM: To investigate the predictors of success in step-down of proton pump inhibitor and to assess the quality of life (QOL). METHODS: Patients who had heartburn twice a week or more were treated with 20 mg omeprazole (OPZ) once daily for 8 wk as an initial therapy (study 1). Patients whose heartburn decreased to once a week or less at the end of the initial therapy were enrolled in study 2 and treated with 10 mg OPZ as maintenance therapy for an additional 6 mo (study 2). QOL was investigated using the gastrointestinal symptom rating scale (GSRS) before initial therapy, after both 4 and 8 wk of initial therapy, and at 1, 2, 3, and 6 mo after starting maintenance therapy. RESULTS: In study 1, 108 patients were analyzed. Their characteristics were as follows; median age: 63 (range: 20-88) years, sex: 46 women and 62 men. The success rate of the initial therapy was 76%. In the patients with successful initial therapy, abdominal pain, indigestion and reflux GSRS scores were improved. In study 2, 83 patients were analyzed. Seventy of 83 patients completed the study 2 protocol. In the per-protocol analysis, 80% of 70 patients were successful for step-down. On multivariate analysis of baseline demographic data and clinical information, no previous treatment for gastroesophageal reflux disease (GERD) [odds ratio (OR) 0.255, 95% CI: 0.06-0.98] and a lower indigestion score in GSRS at the beginning of step-down therapy (OR 0.214, 95% CI: 0.06-0.73) were found to be the predictors of successful step-down therapy. The improved GSRS scores by initial therapy were maintained through the step-down therapy. CONCLUSION: OPZ was effective for most GERD patients. However, those who have had previous treatment for GERD and experience dyspepsia before step-down require particular monitoring for relapse. PMID:21472108

Purpose To investigate the initial clinical value of fluorine 18 ( 18 F) fluorocholine (FCH) dynamic positron emission tomography (PET)/magnetic resonance (MR) imaging by comparing its parameters with clinical-pathologic findings in patients with newly diagnosed intermediate- to high-risk prostate cancer (PCa) who plan to undergo radical prostatectomy. Materials and Methods The institutional review board approved the study protocol, and informed written consent was obtained from all subjects for this HIPAA-compliant study. Twelve men (mean age ± standard deviation, 61.7 years ± 8.4; range, 46-74 years) with untreated intermediate- to high-risk PCa characterized according to Cancer of the Prostate Risk Assessment (CAPRA) underwent preoperative FCH dynamic PET/MR imaging followed by radical prostatectomy between April and November 2015. PET/MR imaging parameters including average and maximum K1 (delivery rate constant) and standardized uptake values (SUVs) and Prostate Imaging Reporting and Data System (PI-RADS) version 2 scores were measured and compared with clinical-pathologic characteristics. For statistical analysis, the Spearman rank correlation and Mann-Whitney U tests were performed. Results Of the PET parameters, maximum SUV of primary tumors showed significant correlations with several clinical-pathologic parameters including serum prostate-specific antigen level (ρ = 0.71, P = .01), pathologic stage (ρ = 0.59, P = .043), and postsurgical CAPRA score (ρ = 0.72, P = .008). The overall PI-RADS score showed significant correlations with pathologic tumor volume (ρ = 0.81, P < .001), percentage of tumor cells with Gleason scores greater than 3 (ρ = 0.59, P = .02), and postsurgical CAPRA score (ρ = 0.58, P = .046).

A method is provided for detecting pathological macromolecules in a patient, comprising obtaining body fluid from the patient, pretreating the body fluid, subjecting the pretreated body fluid to size-exclusion chromatography to create an excluded fluid, and analyzing the excluded fluid to detect macromolecules having a predetermined molecular weight. The method also allows for comparing elution spectra with reference spectra of suspect pathologic proteins.

Patients with gastroesophageal reflux disease (GERD) also have various extra-esophageal symptoms. Laryngopharyngeal reflux disease (LPRD) is a subtype of GERD associated with globus sensation, but proton pump inhibitor (PPI) therapy achieves disappointing results. This study investigated esophageal motility in GERD patients with globus sensation who were resistant to PPI therapy. The subjects were 350 patients with globus sensation. All patients underwent both laryngoscopy and upper gastrointestinal endoscopy to exclude organic disease. After 4 weeks of treatment with rabeprazole sodium (20 mg daily), the patients were divided into PPI-responsive and PPI-resistant groups. Then we investigated esophageal motility in the PPI-resistant group by a multichannel intraluminal impedance and manometry study. A total of 119 patients (55.6%) were resistant to PPI therapy, among whom 57 patients (47.9%) had abnormal esophageal motility. They included 36 patients (66.4%) with ineffective esophageal motility, 9 patients (14.4%) with achalasia, 6 patients (9.6%) with diffuse esophageal spasm, 5 patients (8%) with nutcracker esophagus, and 1 patient (1.6%) with hypertensive lower esophageal sphincter. There were significant differences of upper esophageal sphincter pressure and esophageal body peristalsis between the patients with PPI-resistant LPRD and healthy controls matched for age and sex. Among patients with PPI-resistant LPRD, 47.9% had abnormal esophageal motility.

Clinical examination of the shoulder joint has gained attention as clinicians aim to use an evidence-based examination of the biceps tendon, with the desire for a proper diagnosis while minimizing costly imaging procedures. The purpose of this study is to create a decision tree analysis that enables the development of a clinical algorithm for diagnosing long head of biceps (LHB) pathology. A literature review of Level I and II diagnostic studies was conducted to extract characteristics of clinical tests for LHB pathology through a systematic review of PubMed, Medline, Ovid, and Cochrane Review databases. Tests were combined in series and parallel to determine sensitivities and specificities, and positive and negative likelihood ratios were determined for each combination using a subjective pretest probability. The "gold standard" for diagnosis in all included studies was arthroscopy or arthrotomy. The optimal testing modality was use of the uppercut test combined with the tenderness to palpation of the biceps tendon test. This combination achieved a sensitivity of 88.4% when performed in parallel and a specificity of 93.8% when performed in series. These tests used in combination optimize post-test probability accuracy greater than any single individual test. Performing the uppercut test and biceps groove tenderness to palpation test together has the highest sensitivity and specificity of known physical examinations maneuvers to aid in the diagnosis of LHB pathology compared with diagnostic arthroscopy (practical, evidence-based, comprehensive examination). A decision tree analysis aides in the practical, evidence-based, comprehensive examination diagnostic accuracy post-testing based on the ordinal scale pretest probability.

Among 264 children suspected of GERD, acid GER was confirmed in 138 children on the basis of 24-hour pH monitoring. Comparative analysis of parameters of 24-hour intraesophageal pH monitoring with dual-channel probe (in proximal channel) in children with acid GER: primary and secondary to cow milk allergy and/or other food allergy (CMA/FA) diagnosed; comparison of examined values of pH monitoring parameters with regard to duration of the disease (preliminary study and prospective studies--after 1, 2, 4 and 9 years of clinical observation and/or conservative treatment). 264 children suspected of GERD, aged: 1.5-102 months; x = 20.78 +/- 17.23 months, were enrolled in a study. In order to differentiate acid primary GER from GER secondary to CMA/FA in 138 (52.3%) children with GERD immunoallergological tests were performed. Positive result of oral food challenge test confirmed the allergy being the cause of GER. 138 children with pathological acid GER were qualified into two groups: 1 and 2. Group 1--76 patients (55.1%), aged: 4-102 months; x = 25.2 +/- 27.28 months, with pathological primary GER. Group 2--62 patients (44.9%), aged: 4-74 months; x = 21.53 +/- 17.79 months, with pathological GER secondary to CMA/FA. Significant differentiation of the mean values of these parameters between preliminary study and control studies within groups was shown in the case of: number of episodes of acid GER and duration of the longest episode of acid GER, acid GER index: total and supine (proximal channel). Statistical significance (p < 0.05) was higher in group 1, especially during prospective clinical observation and/or conservative treatment. At the same time significant differentiation of the mean values of: number of episodes of acid GER and episodes of acid GER lasting more than 5 minutes and mean values of acid GER index: total and supine was shown between the groups. Statistical significance (p < 0.05) was higher in group 2. The preliminary study of examined children

The first drug selected for treatment of gastro-oesophageal reflux disease (GERD) and prevention of the recurrence is a proton pump inhibitor (PPI), but recently, a potassium-competitive acid blocker (P-CAB) was put on the market in Japan. Its onset of effect is faster than PPI, and it takes more than 2 days to recover acid secretion after the withdrawal period. Therefore, unlike PPI, the usefulness of every other day administration or discontinuous administration is expected. This study is a prospective, multicentre, open-label, two-period randomised cross-over study to compare the efficacy and safety of PPI every other day administration and P-CAB every other day administration in 120 patients who receive erosive GERD maintenance therapy with PPI. Patients will be randomly allocated to receive 4 weeks P-CAB or PPI followed by 4 weeks cross over, where those on P-CAB will receive PPI and vice versa. The primary endpoint is proportion of asymptomatic patients. Secondary endpoints are suppressive effect of GERD symptoms, proportion of asymptomatic patients at each time point, safety and cost-saving effect of P-CAB every other day administration, compliance with every other day administration, and proportion of asymptomatic patients at the first month of study drug administration. This study was approved by the National Hospital Organization Central Review Board for Clinical Trials (5 December 2017). If P-CAB every other day administration is established as one of GERD maintenance therapies, there is merit in both medical cost reduction and the safety to alleviate elevation in serum gastrin.

There is symptom overlap between gastro-esophageal reflux disease (GERD) and functional dyspepsia (FD). We aimed to test the hypothesis that FD cases are now more likely mislabeled as GERD. In subjects from Olmsted County, MN seen at Mayo Clinic: (i) Investigation of GERD and FD diagnosis rates between 1985 and 2009. (ii) Assessment of survey-based upper gastrointestinal symptoms between 1988 and 2009. (iii) Analysis of patients reporting GERD and/or FD symptoms and subsequently receiving a consistent diagnosis of GERD and/or FD during a medical encounter. (iv) Assess the association between PPI use and GERD and/or FD symptoms and between actual diagnoses received. (i) Yearly GERD diagnosis rates rose between 1985 and 2009 (325-1866 per 100 000). FD diagnosis rates rose from 45 in 1985, to 964 in 1999 but decreased to 452 per 100 000 in 2009. (ii) Reported GERD symptoms did not significantly change between three survey waves in the years 1988-2009 (p = 0.052), whereas FD symptoms slightly increased (p = 0.01). (iii) 62.9% of subjects reporting GERD symptoms received a GERD diagnosis, however only 12.5% of subjects reporting FD symptoms received a FD diagnosis. (iv) PPI use was associated with documented GERD diagnosis (p < 0.001), however there was no significant association between GERD symptoms and PPI use (p = 0.078). We have found evidence supporting a systematic bias away from diagnosing FD, favoring a GERD diagnosis. © 2014 John Wiley & Sons Ltd.

Even compared to other clinical laboratories, the pathological laboratory conducts troublesome work, and many of the work processes are also manual. Therefore, the introduction of the systematic management of administration is necessary. It will be a shortcut to use existing standards such as ISO 15189 for this purpose. There is no standard specialized for the pathological laboratory, but it is considered to be important to a pathological laboratory in particular. 1. Safety nianagement of the personnel and environmental conditions. Comply with laws and regulations concerning the handling of hazardous materials. 2. Pre-examination processes. The laboratory shall have documented procedures for the proper collection and handling of primary samples. Developed and documented criteria for acceptance or rejection of samples are applied. 3. Examination processes. Selection, verification, and validation of the examination procedures. Devise a system that can constantly monitor the traceability of the sample. 4. Post-examination processes. Storage, retention, and disposal of clinical samples. 5. Release of results. When examination results fall within established alert or critical intervals, immediately notify the physicians. The important point is to recognize the needs of the client and be aware that pathological diagnoses are always "the final diagnoses".

Postprandial accumulation of gastric secretions in the proximal stomach above the meal adjacent to the esophagogastric junction (EGJ), referred to as the 'acid pocket', has been proposed as a pathophysiological factor in gastro-esophageal reflux disease (GERD) and as a target for GERD treatment. This study assessed the effect of proton pump inhibitor (PPI) therapy on the volume, distribution and acidity of gastric secretions in GERD and healthy subjects (HS). A randomized, double blind, cross-over study in 12 HS and 12 GERD patients pre-treated with 40 mg pantoprazole (PPI) or placebo b.i.d. was performed. Postprandial secretion volume (SV), formation of a secretion layer and contact between the layer and the EGJ were quantified by Magnetic Resonance Imaging (MRI). Multi-channel pH-monitoring assessed intragastric pH. A distinct layer of undiluted acid secretion was present on top of gastric contents in almost all participants on and off high-dose acid suppression. PPI reduced SV (193 ml to 100 ml, in HS, 227 ml to 94 ml in GERD; p < 0.01) and thickness of the acid layer (26 mm to 7 mm, 36 mm to 9 mm respectively, p < 0.01). No differences in secretion volume or layer thickness were observed between groups; however, off treatment, contact time between the secretion layer and EGJ was 2.6 times longer in GERD compared to HS (p = 0.012). This was not the case on PPI. MRI can visualize and quantify the volume and distribution dynamics of gastric secretions that form a layer in the proximal stomach after ingestion of a liquid meal. The secretion volume and the secretion layer on top of gastric contents is similar in GERD patients and HS; however contact between the layer of undiluted secretion and the EGJ is prolonged in patients. High dose PPI reduced secretion volume by about 50% and reduced contact time between secretion and EGJ towards normal levels. NCT01212614.

Boredom proneness in pathological gambling.

To test the hypothesis that pathological gamblers seek stimulation as a means of reducing aversive under-aroused states of boredom and/or depression, the Beck Depression Inventory, Zuckerman's Sensation Seeking Scale and a Boredom Proneness Scale were administered to 48 diagnosed pathological gamblers and a control group of 40 family physician patients. Analyses of variance showed pathological gamblers obtained significantly higher boredom proneness and depression scores than those of controls. That the Boredom Proneness Scale failed to correlate with the Zuckerman Boredom Susceptibility subscale suggested the two measure differing dimensions. Results indicated the possible existence of three subtypes of pathological gamblers, one group characterized by boredom, another by depression, and a third by a mixture of both depression and boredom.

Chronic obstructive pulmonary disease (COPD) patients have a high incidence of gastroesophageal reflux disease (GERD) whose pathophysiology seems to be linked to an increased trans-diaphragmatic pressure gradient and not to a defective esophagogastric barrier. Inhaled beta agonist bronchodilators are a common therapy used by patients with COPD. This drug knowingly not only leads to a decrease in the lower esophageal sphincter (LES) resting pressure, favoring GERD, but also may improve ventilatory parameters, therefore preventing GERD. This study aims to evaluate the effect of inhaled beta agonist bronchodilators on the trans-diaphragmatic pressure gradient and the esophagogastric barrier. We studied 21 patients (mean age 67 years, 57 % males) with COPD and GERD. All patients underwent high-resolution manometry and esophageal pH monitoring. Abdominal and thoracic pressure, trans-diaphragmatic pressure gradient (abdominal-thoracic pressure), and the LES retention pressure (LES basal pressure-transdiaphragmatic gradient) were measured before and 5 min after inhaling beta agonist bronchodilators. The administration of inhaled beta agonist bronchodilators leads to the following: (a) a simultaneous increase in abdominal and thoracic pressure not affecting the trans-diaphragmatic pressure gradient and (b) a decrease in the LES resting pressure with a reduction of the LES retention pressure. In conclusion, inhaled beta agonist bronchodilators not only increase the thoracic pressure but also lead to an increased abdominal pressure favoring GERD by affecting the esophagogastric barrier.

Ameloblastomas are odontogenic tumors that can present some distinct clinicopathological profiles when comparing different populations and studies. Objectives: The aim of the present study was to analyze the clinicopathological features from a series of ameloblastomas diagnosed in a single Oral Pathology service in Brazil in an 8-year period. Study Design: The files were revised and all cases diagnosed as ameloblastomas in the period were retrieved. All hematoxylin and eosin stained histological slides were reviewed and all clinical and radiological information were obtained through a review of the laboratory forms. Data were descriptively analyzed and a comparison was performed with the different ameloblastomas subtypes. Results: Seventy ameloblastomas composed the final sample, including 57 (81%) solid/multicystic, 9 (13%) unicystic, 2 (3%) desmoplastic and 2 (3%) peripheral ameloblastomas. Mean age of the affected patients was in the forth decade of life and there was a slight male predominance. Most tumors presented as multilocular radiolucencies, were located in the posterior mandible and showed the follicular and plexiform histological patterns. There was no difference on the mean age of the patients affected by solid and unicystic ameloblastomas. Conclusions: The present results showed that the clinicopathological features of the ameloblastomas included in this Brazilian sample were similar to the features described in most other worldwide populations. Key words:Ameloblastoma, solid, unicystic, review, epidemiology, histology. PMID:25129244

Magnetic sphincter augmentation (MSA) is approved for uncomplicated GERD. Multiple studies have shown MSA to compare favorably to laparoscopic Nissen fundoplication (LNF) in terms of symptom control with results out to 5 years. The MSA device itself, however, is an added cost to an anti-reflux surgery, and direct cost comparison studies have not been done between MSA and LNF. The aim of the study was to compare charges, complications, and outcome of MSA versus LNF at 1 year. This is a retrospective analysis of all patients who underwent MSA or LNF for the treatment of GERD between January 2010 and June 2013. Patient charges were collected for the surgical admission. We also collected data on 30-day complications and symptom control at 1 year assessed by GERD-HRQL score and PPI use. There were 119 patients included in the study, 52 MSA and 67 LNF. There was no significant difference between the mean charges for MSA and LNF ($48,491 vs. $50,111, p = 0.506). There were significant differences in OR time (66 min MSA vs. 82 min LNF, p < 0.01) and LOS (17 h MSA vs. 38 h LNF, p < 0.01). At 1-year follow-up, mean GERD-HRQL was 4.3 for MSA versus 5.1 for LNF (p = 0.47) and 85 % of MSA patients versus 92 % of LNF patients were free from PPIs (p = 0.37). MSA patients reported less gas bloat symptoms (23 vs. 53 %, p ≤ 0.01) and inability to belch (10 vs. 36 %, p ≤ 0.01) and vomit (4 vs. 19 %, p ≤ 0.01). The side effect profile of MSA is better than LNF as evidenced by less gas bloat and increase ability to belch and vomit. LNF and MSA are comparable in symptom control, safety, and overall hospital charges. The charge for the MSA device is offset by less charges in other categories as a result of the shorter operative time and LOS.

Proton pump inhibitor-responsive esophageal eosinophilia: a historical perspective on a novel and evolving entity.

PubMed

Molina-Infante, Javier; Katzka, David A; Dellon, Evan S

2015-01-01

Eosinophilic esophagitis (EoE) is an emerging chronic esophageal disease, first described in 1993, with a steadily increasing incidence and prevalence in western countries. Over the 80's and early 90's, dense esophageal eosinophilia was mostly associated gastroesophageal reflux disease (GERD). For the next 15 years, EoE and GERD were rigidly considered separate entities: Esophageal eosinophilia with pathological acid exposure on pH monitoring or response to proton pump inhibitor (PPI) therapy was GERD, whereas normal pH monitoring or absence of response to PPIs was EoE. Updated guidelines in 2011 described a novel phenotype, proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE), referring to patients who appear to have EoE clinically, but who achieve complete remission after PPI therapy. Currently, PPI-REE must be formally excluded before diagnosing EoE, since 30-40% of patients with suspected EoE are eventually diagnosed with PPI-REE.Interestingly, PPI-REE and EoE remain undistinguishable based on clinical, endoscopic, and histological findings, pH monitoring, and measurement of tissue markers and cytokines related to eosinophilic inflammation.This review article aims to revisit the relatively novel concept of PPI-REE from a historical perspective, given the strong belief that only GERD, as an acid peptic disorder, could respond to the acid suppressing ability of PPI therapy, is becoming outdated. Evolving evidence suggests that PPI-REE is genetically and phenotypically undistinguishable from EoE and PPI therapy alone can almost completely reverse allergic inflammation. As such, PPI-REE might constitute a subphenotype of EoE and PPI therapy may be the first therapeutic step and diet/ steroids may represent step up therapy. Possibly, the term PPI-REE will be soon replaced by PPI-responsive EoE. The mechanism as to why some patients respond to PPI therapy (PPI-REE) while others do not (EoE), remains to be elucidated.

To estimate esophageal and gastric pH values on an empty stomach and after stimulation of gastric secretion and gastric and duodenal motor-evacuatory activity in patients with gastroesophageal reflux disease (GERD) associated with pathological refluxes, such as gastroesophageal reflux (GER) and duodenogastroesophageal reflux (DGER). The observational cross-sectional study was conducted to investigate and compare the parameters of intraesophageal and intragastric pH metry and peripheral electrogastroenterography in 103 GERD patients with endoscopically positive distal reflux esophagitis in GER and DGER. The patients with GERD developed pathological esophageal refluxes (both GER and DGER) in various degrees of impaired gastric production, from anacidity to hyperacidity. The patients with predominant DGER were found to have gastric hyperacidity and normal acidity slightly less frequently than those with predominant GER. The patients with GERD developing in the presence of predominant GER had moderate gastric stasis with discoordinated antroduodenal propulsion resulting from hypomotor dyskinesia of the stomach and duodenum. When DGER was predominant in the patients with GERD, the signs of gastric stasis and duodenal hyperkinesia were concurrent with discoordinated antroduodenal and duodenojejunal propulsion. The specific features of the esophagogastroduodenal secretory and motor evacuatory disorders found create conditions for the pathological refluxes into the esophagus, which differ in the composition of refluxate.

The clinical syndrome of primary progressive aphasia (PPA) can be associated with a variety of neuropathologic diagnoses at autopsy. Thirty percent of cases have Alzheimer disease (AD) pathology, most often in the usual distribution, which defies principles of brain–behavior organization, in that aphasia is not symptomatic of limbic disease. The present study investigated whether concomitant TDP-43 pathology could resolve the lack of clinicoanatomic concordance. In this paper, 16 cases of clinical PPA and 10 cases of primarily non-aphasic frontotemporal dementia (FTD), all with AD pathology, were investigated to determine whether their atypical clinical phenotypes reflected the presence of additional TDP-43 pathology. A comparison group consisted of 27 cases of pathologic AD with the typical amnestic clinical phenotype of probable AD. Concomitant TDP-43 pathology was discovered in only three of the FTD and PPA but in more than half of the typical amnestic clinical phenotypes. Hippocampal sclerosis (HS) was closely associated with TDP-43 pathology when all groups were combined for analysis. Therefore, the clinical phenotypes of PPA and FTD in cases with pathologic AD are only rarely associated with TDP-43 proteinopathy. Furthermore, medial temporal TDP-43 pathology is more tightly linked to HS than to clinical phenotype. These findings challenge the current notions about clinicopathologic correlation, especially about the role of multiple pathologies. PMID:20361198

Given the crucial role of pathology reporting in the management of breast cancers, we aimed to investigate the quality and variability of breast cancer pathology reporting in Belgium. Detailed information on non-molecular and molecular parameters was retrieved from the pathology protocols available at the Belgian Cancer Registry for 10,007 breast cancers diagnosed in Belgium in 2008. Substantial underreporting was shown for several clinically relevant non-molecular parameters, such as lymphovascular invasion. High-volume laboratories performed only slightly better than others, and analyses at the individual laboratory level showed clear inter-laboratory variability in reporting for all volume categories. Information on ER/PR and HER2 IHC was mentioned in respectively 91.7% and 90.8% of evaluative cases. HER2 ISH data were available for 78.5% of the cases judged to be 2+ for HER2 IHC. For cases with different specimens analysed, discordance between these specimens was highest for HER2, followed by PR. For HER2, results obtained from different laboratories were even less concordant. In addition, inter-laboratory differences were noted in the used ER/PR scoring systems, the proportion of ER-/PR+ cases, and the relation between histological grade and ER/PR positivity. Data on Ki67 were only available for 43.8% of the investigated cases, and showed inconsistent use of cut-off values. Breast pathology reporting in Belgium in 2008 was suboptimal and showed considerable inter-laboratory variability. Synoptic reporting has been proposed as a facilitator towards increased reporting quality and harmonization, but the lack of aligned informatics remains a major hurdle in its concrete implementation.

Recent studies have shown that the peripheral inflammation may cause the up-regulation of central nervous system inflammation and therefore possibly plays a vital role in the pathophysiology of subsequent psychiatric disorders. We explored the relationship between gastroesophageal reflux disease (GERD) and the subsequent development of psychiatric disorders including schizophrenia as well as bipolar, depressive, anxiety, and sleep disorders. We investigated patients who were diagnosed with GERD according to the data in the Taiwan National Health Insurance Research Database. A comparison cohort comprised patients without GERD who were matched according to age and sex. The incidence rate and the hazard ratios (HRs) of subsequent new-onset psychiatric disorders were calculated for both cohorts, based on the diagnoses of psychiatrists. The GERD cohort consisted of 3813 patients, and the comparison cohort comprised 15,252 matched control patients without GERD. The risks of depressive disorder (HR=3.37, 95% confidence interval [CI]=2.49-4.57), anxiety disorder (HR=2.99, 95% CI=2.12-4.22), and sleep disorder (HR=2.69, 95% CI=1.83-3.94), were higher in the GERD cohort than in the comparison cohort. In addition, the incidence of newly diagnosed depressive, anxiety, and sleep disorders remained significantly increased in all of the stratified follow-up durations (0-1, ≥1year). GERD may increase the risks of subsequent depressive, anxiety, and sleep disorders. These psychiatric disorders have a negative effect on people's quality of life. Clinicians should pay a particular attention to psychiatric comorbidities in GERD patients. Copyright © 2015 European Federation of Internal Medicine. Published by Elsevier B.V. All rights reserved.

The purpose of this study was to investigate the impact of gastroesophageal reflux disease (GERD) on dental erosion (DE) in children and analyze the association between dental erosion and diet, oral hygiene, and sociodemographic characteristics. This case-control study encompassed 43 two- to 14-year-olds diagnosed positive for GERD by the 24-hour pH monitoring, paired by age group with 136 healthy controls, in Belo Horizonte, Minas Gerais, Brazil. DE was assessed by one calibrated examiner using the O'Sullivan index. A questionnaire was self-administered by parents collecting information regarding sociodemographics, oral hygiene, and dietary habits. Dental erosion experience was compared between the groups, and a stratified analysis was performed (P<0.05). Dental erosion was diagnosed in 10.6 percent (N equals 19) of all the children; 25.6 percent (N equals 11) of GERD children and 5.9 percent (N equals eight) of children without GERD, P=0.001). Dental erosion was not associated with dietary consumption or sociodemographic characteristics in both groups (P≥0.05). Children who used adult toothpaste had a 5.79 higher chance of having dental erosion in the group with GERD. Children diagnosed with gastroesophageal reflux disease were at an increased risk of having dental erosion when compared to healthy subjects; among the GERD children, dental erosion was associated with the use of adult toothpaste.

SUMMARY Children with GERD may benefit from gastric acid suppression with proton pump inhibitors such as pantoprazole. Effective treatment with pantoprazole requires correct dosing and understanding of the drug’s kinetic profile in children. The aim of these studies was to characterize the pharmacokinetic (PK) profile of single and multiple doses of pantoprazole delayed-release tablets in pediatric patients with GERD aged ≥6 through 11 years (study 1) and 12 through 16 years (study 2). Patients were randomly assigned to receive pantoprazole 20 or 40 mg once daily. Plasma pantoprazole concentrations were obtained at intervals through 12 hours after the single dose, and at 2 and 4 hours after multiple doses for PK evaluation. PK parameters were derived by standard noncompartmental methods and examined as a function of both drug dose and patient age. Safety was also monitored. Pantoprazole PK was dose independent (when dose normalized) and similar toPK reported from adult studies. There was no evidence of accumulation with multiple dosing or reports of serious drug-associated adverse events. In children aged 6 to 16 years with GERD, currently available pantoprazole delayed-release tablets can be used to provide systemic exposure similar to that in adults. PMID:20852004

The pathological manifestations in the kidneys in systemic lupus erythematosus (SLE) are commonly known as lupus nephritis. We have studied the pathological changes in renal biopsies from 59 cases of clinically diagnosed SLE obtained over a 15-year period from a racially diverse population in the Sydney metropolitan area. Our aim was to see if there was any regional variation in the morphological changes. Renal biopsy changes were assessed by routine light, immunofluorescence, and electron microscopy. We used the modified 1974 World Health Organization classification of lupus nephritis to classify cases into six classes. Disease severity was assessed by age, sex, and across racial groups, including Caucasian, Asian, Middle Eastern, Mediterranean, Indian subcontinental, South American, and Pacific Islander. Our analysis showed that cases of lupus nephritis contributed 5.4% of our total renal biopsies examined over a 15-year period. The overall incidence of biopsy-proven cases was 0.49 per 100,000 per year. The ages of our patients ranged from 10 to 79 years, with most below 50 years of age. A female to male ratio was determined to be 4.4:1. There was no relationship to ethnicity, nor was there a relationship between any of these parameters and the class or severity of disease. Renal biopsy with multimodal morphological and immunohistochemical analysis remains the gold standard for diagnosis and determination of the level of disease in lupus nephritis. Based on this approach we have identified an incidence rate for southwest Sydney that is slightly higher but comparable to that found in a similar study from the United Kingdom. We also found that there was no relationship between sex, race, or age and severity of disease.

Gastroesophageal reflux disease (GERD) can mimic epileptic seizure, and may be misdiagnosed as epilepsy. On the other hand, GERD can be more commonly seen in children with neurological disorders such as cerebral palsy (CP); this co-incidence may complicate the management of patients by mimicking refractory seizures. The purpose of our study was to evaluate the clinical features, definite diagnoses and treatment approaches of the patients with clinically suspected GERD who were referred to the division of pediatric neurology with a suspected diagnosis of epileptic seizure. We also aimed to investigate the occurrence of GERD in children with epilepsy and/or CP. Fifty-seven children who had a final diagnosis of GERD but were initially suspected of having epileptic seizures were assessed prospectively. All patients were assigned to 3 groups according to definite diagnoses as follows: patients with only GERD who were misdiagnosed as having epileptic seizure (group 1: n=16; 28.1%), those with comorbidity of epilepsy and GERD (group 2: n=21; 36.8%), and those with the coexistence of GERD with epilepsy and CP (group 3: n=20; 35.1%). Five patients (8.8%) did not respond to anti-reflux treatment and laparoscopic reflux surgery was performed. The positive effect of GERD therapy on paroxysmal nonepileptic events was observed in 51/57 (89.5%) patients. GERD is one of the important causes of paroxysmal nonepileptic events. In addition, GERD must be kept in mind at the initial diagnosis and also in the long-term management of patients with neurological disorders such as epilepsy and CP.

Gastroesophageal reflux disease (GERD) has become the most commonly seen gastrointestinal disorder in outpatient clinics. In the United States, around 20% of the general population experience heartburn on a weekly basis. Although clinical complaints can be mild or moderate, patients with GERD may develop further complications, such as peptic strictures, Barrett's esophagus (BE), and even esophageal adenocarcinoma (EAC). Pathologically, GERD is developed as a result of chronic and enhanced exposure of the esophageal epithelium to noxious gastric refluxate. In this review article, we provide an overview of GERD, and then focus on the roles of stromal cells, interleukin 4 (IL-4), and adiponectin in GERD and BE. The importance of inflammation and immunomodulators in GERD pathogenesis is highlighted. Targeting the immunomodulators or inflammation in general may improve the therapeutic outcome of GERD, in particular, in those refractory to proton pump inhibitors. PMID:27441783

Bone Sarcoma Pathology: Diagnostic Approach for Optimal Therapy.

PubMed

Rosenberg, Andrew E

2017-01-01

The pathologic interpretation of malignant bone tumors is one of the more challenging areas in surgical pathology. This is based on the reality that primary bone sarcomas are uncommon, demonstrate significant morphologic heterogeneity, and have a broad spectrum of biology. Accordingly, it is difficult for pathologists to acquire the necessary experience to confidently and accurately diagnose bone sarcomas. The task is further complicated by the fact that it requires the integration of clinical and radiologic information into the diagnostic process. Lastly, molecular aberrations in sarcomas are being newly discovered and their identification is often critical to make specific diagnoses. The pathologist's role in guiding optimal treatment in biopsy specimens is to make an accurate diagnosis and provide the grade and molecular aberrations when appropriate. The pathology report of resected tumors must confirm this information and assess the surgical resection margins and the percentage of necrosis if the sarcoma has been treated with neoadjuvant systemic therapy.

Pathological diagnosis involves very delicate and complex consequent processing that is conducted by a pathologist. The recognition of false patterns might be an important cause of misdiagnosis in the field of surgical pathology. In this study, we evaluated the influence of visual and cognitive bias in surgical pathologic diagnosis, focusing on the influence of "mental rotation." We designed three sets of the same images of uterine cervix biopsied specimens (original, left to right mirror images, and 180-degree rotated images), and recruited 32 pathologists to diagnose the 3 set items individually. First, the items found to be adequate for analysis by classical test theory, Generalizability theory, and item response theory. The results showed statistically no differences in difficulty, discrimination indices, and response duration time between the image sets. Mental rotation did not influence the pathologists' diagnosis in practice. Interestingly, outliers were more frequent in rotated image sets, suggesting that the mental rotation process may influence the pathological diagnoses of a few individual pathologists. © Copyright: Yonsei University College of Medicine 2018.

Time trends of US hospitalization for esophageal disease.

The occurrence of reflux disease seems to be rising in the United States. The aim of the present study was to follow the time trends of hospitalization for gastroesophageal reflux disease (GERD) and other esophageal disease during the past 4 decades. US hospital utilization data were available for individual years from 1970 to 2010 through the National Hospital Discharge Survey. Esophageal diagnoses were stratified by their ninth revision of the International Classification of Diseases codes. Annual hospitalizations were expressed as rates per 100,000 living US population. GERD was by far the most common esophageal disorder resulting in hospitalization. However, in only 5% of instances did GERD-related diagnoses constitute the primary cause of hospitalization. Between 1970 and 2010 the rates of GERD-related hospitalizations increased in an exponential manner almost 10-fold. This rise affected both sex and all age groups alike. A 3-fold rise was noted in hospitalizations for esophageal adenocarcinoma. Other esophageal diagnoses, such as achalasia, dyskinesia, or stricture were characterized by falling or stable trends. US hospitalization data show a continued exponential rise in the occurrence of GERD without any signs of leveling off. These trends are likely to represent ongoing changes in the underlying incidence and prevalence of the disease.

Progressive supranuclear palsy (PSP) is a neuropathologically defined disease presenting with a broad spectrum of clinical phenotypes. To identify clinical features and investigations that predict or exclude PSP pathology during life, aiming at an optimization of the clinical diagnostic criteria for PSP. We performed a systematic review of the literature published since 1996 to identify clinical features and investigations that may predict or exclude PSP pathology. We then extracted standardized data from clinical charts of patients with pathologically diagnosed PSP and relevant disease controls and calculated the sensitivity, specificity, and positive predictive value of key clinical features for PSP in this cohort. Of 4166 articles identified by the database inquiry, 269 met predefined standards. The literature review identified clinical features predictive of PSP, including features of the following 4 functional domains: ocular motor dysfunction, postural instability, akinesia, and cognitive dysfunction. No biomarker or genetic feature was found reliably validated to predict definite PSP. High-quality original natural history data were available from 206 patients with pathologically diagnosed PSP and from 231 pathologically diagnosed disease controls (54 corticobasal degeneration, 51 multiple system atrophy with predominant parkinsonism, 53 Parkinson's disease, 73 behavioral variant frontotemporal dementia). We identified clinical features that predicted PSP pathology, including phenotypes other than Richardson's syndrome, with varying sensitivity and specificity. Our results highlight the clinical variability of PSP and the high prevalence of phenotypes other than Richardson's syndrome. The features of variant phenotypes with high specificity and sensitivity should serve to optimize clinical diagnosis of PSP. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and Movement Disorder Society.

To determine if patients evaluated using the pediatric chest pain standardized clinical assessment and management plan (SCAMP) in cardiology clinic were later diagnosed with unrecognized cardiac pathology, and to determine if other patients with cardiac pathology not enrolled in the SCAMP would have been identified using the algorithm. Patients 7-21 years of age, newly diagnosed with hypertrophic or dilated cardiomyopathy, coronary anomalies, pulmonary embolus, pulmonary hypertension, pericarditis, or myocarditis were identified from the Boston Children's Hospital (BCH) cardiac database between July 1, 2010 and December 31, 2012. Patients were cross-referenced to the SCAMP database or retrospectively assessed with the SCAMP algorithm. Among 98 patients with cardiac pathology, 34 (35%) reported chest pain, of whom 10 were diagnosed as outpatients. None of these patients were enrolled in the SCAMP because of alternate chief complaints (n = 4) or referral to BCH for management of the new diagnosis (n = 6). Each of these patients would have had an echocardiogram recommended by retrospective application of the SCAMP algorithm. Two other patients with cardiac pathology were among the 1124 patients assessed by the SCAMP. One patient initially diagnosed with noncardiac chest pain presented 18 months later and was diagnosed with myocarditis as an inpatient. One patient seen initially in the emergency department was subsequently diagnosed with pericarditis as an outpatient. Patients assessed by the chest pain SCAMP at BCH were not later diagnosed with cardiac pathology that was missed at the initial encounter. Nonenrolled outpatients with cardiac pathology and chest pain would have been successfully identified with the SCAMP algorithm. © 2016 Wiley Periodicals, Inc.

Little is known about the distribution of diagnoses that account for fatigue in patients in primary care. We evaluated the diagnoses established within 1 year after presentation with fatigue in primary care that were possibly associated with the fatigue. We conducted a prospective observational cohort study with 1-year follow-up. We included adult patients who presented with a new episode of fatigue between June 2004 and January 2006. We extracted data on diagnoses during the follow-up period from the patients' medical records as well as data on pre-existing chronic diseases. Of the 571 patients for whom diagnostic data were available, 268 (46.9%) had received one or more diagnoses that could be associated with fatigue. The diagnoses were diverse and mostly included symptom diagnoses, with main categories being musculoskeletal (19.4%) and psychological problems (16.5%). Clear somatic pathology was diagnosed in 47 (8.2%) of the patients. Most diagnoses were not made during the consultation when fatigue was presented. Only a minority of patients were diagnosed with serious pathology. Half of the patients did not receive any diagnosis that could explain their fatigue. Nevertheless, because of the wide range of conditions and symptoms that may explain or co-occur with the fatigue, fatigue is a complex problem that deserves attention not only as a symptom of underlying specific disease.

A 80-years-old woman suddenly presented with aphasia, right hemiparesis, and dysesthesia. MRA showed the left middle cerebral artery occlusion. She was diagnosed as hyperacute ischemic stroke. She was treated with intravenous recombinant tissue plasminogen activator and underwent endovascular thrombectomy. On admission, she had a fever and high C reactive protein, and was treated with antibiotic therapy. The pathological diagnosis of the retrieved thrombus revealed the cluster of the gram positive cocci. The blood culture was negative and thransthoracic echocardiogram did not detect the vegetation. She was finally diagnosed as cardioembolic stroke due to infective endocarditis based on the pathological diagnosis of the retrieved thrombus. The pathological diagnosis of the retrieved thrombus was quite important to clarify the cause of ischemic stroke.

An international group of experts evaluated and revised recommendations for ambulatory reflux monitoring for the diagnosis of gastro-esophageal reflux disease (GERD). Literature search was focused on indications and technical recommendations for GERD testing and phenotypes definitions. Statements were proposed and discussed during several structured meetings. Reflux testing should be performed after cessation of acid suppressive medication in patients with a low likelihood of GERD. In this setting, testing can be either catheter-based or wireless pH-monitoring or pH-impedance monitoring. In patients with a high probability of GERD (esophagitis grade C and D, histology proven Barrett's mucosa >1 cm, peptic stricture, previous positive pH monitoring) and persistent symptoms, pH-impedance monitoring should be performed on treatment. Recommendations are provided for data acquisition and analysis. Esophageal acid exposure is considered as pathological if acid exposure time (AET) is greater than 6% on pH testing. Number of reflux episodes and baseline impedance are exploratory metrics that may complement AET. Positive symptom reflux association is defined as symptom index (SI) >50% or symptom association probability (SAP) >95%. A positive symptom-reflux association in the absence of pathological AET defines hypersensitivity to reflux. The consensus group determined that grade C or D esophagitis, peptic stricture, histology proven Barrett's mucosa >1 cm, and esophageal acid exposure greater >6% are sufficient to define pathological GERD. Further testing should be considered when none of these criteria are fulfilled. © 2017 John Wiley & Sons Ltd.

Intertumor heterogeneity has been proposed as a potential mechanism to account for variability in cognitive performance in women diagnosed with breast cancer. The purpose of this study was to explore associations between variation in pathologic tumor features (PTFs) and variability in preadjuvant therapy cognitive performance in postmenopausal women newly diagnosed with early-stage breast cancer. Participants (N = 329) completed a comprehensive battery of neuropsychological tests to evaluate cognitive performance after primary surgery but prior to initiation of adjuvant anastrozole±chemotherapy. PTF data were abstracted from medical records. Robust multiple linear regression models were fit to estimate associations between individual PTFs and the cognitive function composite domain scores. All models controlled for age, estimated intelligence, and levels of depressive symptoms, anxiety, fatigue, and pain. Diagnosis of a HER2-positive tumor contributed to poorer verbal (b = -0.287, P = 0.018), visual (b = -0.270, P = 0.001), and visual working (b = -0.490, P < 0.001) memory performance compared to diagnosis of a HER2-negative tumor. Similarly, as HER2 immunohistochemistry classification score increased, verbal (b = -0.072, P = 0.093), visual (b = -0.081, P = 0.003), and visual working (b = -0.170, P < 0.001) memory performance score decreased. Associations with performance were also noted between location, focality/centricity, hormone receptor expression, cellular proliferation (i.e., Ki67), and Oncotype DX ® Breast Cancer Assay Recurrence Score ® .) Our results suggest that certain PTFs related to more aggressive tumor phenotypes or inferior breast cancer prognosis may be implicated in poorer preadjuvant therapy cognitive performance. Follow-up studies that include a cognitive assessment before primary surgery should be conducted to further delineate the role of intertumor heterogeneity on cognitive performance. © 2016 The Authors

A prime concern for gastroesophageal reflux disease (GERD) patients is fast symptom control. Sparse valid information is available on the rapidity of the effect of proton pump inhibitors in providing symptom relief. The new reflux questionnaire ReQuest is validated for daily assessment of changes in GERD symptoms. Therefore, this study investigated the efficacy of 20 mg pantoprazole and 20 mg esomeprazole with regard to the time to symptom relief in patients with endoscopy-negative GERD (enGERD) using ReQuest. 529 patients were treated with pantoprazole or esomeprazole over 4 weeks. ReQuest symptom scores were assessed daily. The mean and median times to first and sustained symptom relief were determined. Median time to first symptom relief was 2 days for both drugs (intention-to-treat population). The median time to sustained symptom relief was 3 days shorter with pantoprazole (10.0 vs. 13.0 days). The Hodges-Lehmann estimator for the difference in time to reach first and sustained symptom relief between both groups was 0.00 days. For both variables the one-sided 95% CI (Moses) was [0.00; infinity[, documenting no significant differences between the treatment groups. The rapidity of symptom control can be evaluated by clinically significant parameters using ReQuest. Pantoprazole and esomeprazole are equally effective in the time to first and sustained symptom relief. Copyright 2007 S. Karger AG, Basel.

The coexistence of gastroesophageal reflux disease (GERD) and COPD has been recognized, but there has been no comprehensive evaluation of the impact of GERD on COPD-related health status and patient-centered outcomes. Cross-sectional and longitudinal study of 4,483 participants in the COPDGene cohort who met GOLD criteria for COPD. Physician-diagnosed GERD was ascertained by questionnaire. Clinical features, spirometry and imaging were compared between COPD subjects without versus with GERD. We evaluated the relationship between GERD and symptoms, exacerbations and markers of microaspiration in univariate and multivariate models. Associations were additionally tested for the confounding effect of covariates associated with a diagnosis of GERD and the use of proton-pump inhibitor medications (PPIs). To determine whether GERD is simply a marker for the presence of other conditions independently associated with worse COPD outcomes, we also tested models incorporating a GERD propensity score. GERD was reported by 29% of subjects with female predominance. Subjects with GERD were more likely to have chronic bronchitis symptoms, higher prevalence of prior cardiovascular events (combined myocardial infarction, coronary artery disease and stroke 21.3% vs. 13.4.0%, p < 0.0001). Subjects with GERD also had more severe dyspnea (MMRC score 2.2 vs. 1.8, p < 0.0001), and poorer quality of life (QOL) scores (St. George's Respiratory Questionnaire (SGRQ) total score 41.8 vs. 34.9, p < 0.0001; SF36 Physical Component Score 38.2 vs. 41.4, p < 0.0001). In multivariate models, a significant relationship was detected between GERD and SGRQ (3.4 points difference, p < 0.001) and frequent exacerbations at baseline (≥2 exacerbation per annum at inclusion OR 1.40, p = 0.006). During a mean follow-up time of two years, GERD was also associated with frequent (≥2/year exacerbations OR 1.40, p = 0.006), even in models in which PPIs, GERD-PPI interactions and a

Cerebral amyloid angiopathy (CAA) is a degenerative disorder characterized by amyloid-β (Aβ) deposition in the brain microvessels. CAA is also known to contribute not only to cortical microbleeds but also lobar hemorrhages. This retrospective study examined CAA pathologically in patients who underwent direct surgeries for lobar hemorrhage. Thirty-three patients with lobar hemorrhage underwent open surgery with biopsy from 2007 to 2016 in our hospital. Cortical tissues over hematomas obtained surgically were pathologically examined using hematoxylin, eosin stain, and anti-Aβ antibody to diagnose CAA. We also investigated the advanced degree of CAA and clinical features of each patient with lobar hemorrhage. In the 33 patients, 4 yielded specimens that were insufficient to evaluate CAA pathologically. Twenty-four of the remaining 29 patients (82.8%) were pathologically diagnosed with CAA. The majority of CAA-positive patients had moderate or severe CAA based on a grading scale to estimate the advanced degree of CAA. About half of the CAA-positive patients had hypertension, and four took anticoagulant or antiplatelet agents. In five patients who were not pathologically diagnosed with CAA, one had severe liver function disorder, three had uncontrollable hypertension, and one had no obvious risk factor. Our pathological findings suggest that severe CAA with vasculopathic change markedly contributes to lobar hemorrhage. The coexistence of severe CAA and risk factors such as hypertension, anticoagulants or antiplatelets may readily induce lobar hemorrhage.

Published reports have shown the prevalence and incidence of gastroesophageal reflux disease (GERD) is increasing in Japan. The objective of this study is to examine change in GERD incidence, and to understand current patient demographics, medical costs, treatment status, and the suitability of current treatment based on analysis of an insurance claims database. An insurance claims database with data on ∼1.9 million company employees from January 2005 to May 2015 was used. Prevalence, demographics, and medical costs were analyzed by cross-sectional analysis, and incidence and treatment status were analyzed by longitudinal analysis among newly-diagnosed GERD patients. GERD prevalence in 2014 was 3.3% among 20-59 year-olds, accounting for 40,134 people in the database, and GERD incidence increased from 0.63% in 2009 to 0.98% in 2014. In 2014, mean medical cost per patient per month for GERD patients aged 20-59 was JPY 31,900 (USD 266 as of January 2016), which was ∼2.4-times the mean national healthcare cost. The most frequently prescribed drugs for newly-diagnosed GERD patients were proton pump inhibitors (PPIs). Although PPIs were prescribed more often in patients with more doctor visit months, over 20% of patients that made frequent doctor visits (19 or more visits during a 24 calendar months period) were prescribed PPIs during only 1 calendar month or not at all. The database included only reimbursable claims data and, therefore, did not cover over-the-counter drugs. The database also consisted of employee-based claims data, so included little data on people aged 60 years and older. Given the increasing incidence of GERD in Japan there is a need for up-to-date information on GERD incidence. This study suggests that some GERD patients may not be receiving appropriate treatment according to Japanese guidelines, which is needed to improve symptom control.

This 2015 study investigated whether Lebanese paediatricians diagnosed and managed gastro-oesophageal reflux disease (GERD) in infants and children in accordance with the 2009 guidelines from the North American and European Societies for Paediatric Gastroenterology, Hepatology and Nutrition. Paediatricians members of the Lebanese Order of Physicians with updated email addresses were invited to complete a web-based survey between September and November 2015, to assess their knowledge and management of GERD. Responses were received from 114 of the 543 paediatricians, and 96 were analysed. Only two respondents complied fully with the international guidelines. The majority diagnosed GERD in infants based solely on their medical history and examination. Moreover, nearly two-thirds of the respondents would start an empiric trial with acid suppression. Around half of the respondents considered proton pump inhibitors to be the mainstay of GERD treatment. This was the first Lebanese study that surveyed the management of paediatric GERD. Only 2.1% of the paediatricians followed the guidelines on the evidence-based management of GERD. This highlights the need for studies to assess barriers to guideline implementation and the development of new guidelines accounting for regional factors, mainly the cost of investigations and prevalence of medical insurance. ©2016 Foundation Acta Paediatrica.

Pulmonary neuroendocrine tumors (pNETs) are difficult to classify. We performed a population-based analysis to investigate the application of pNET nomenclature in daily pathology practice. Conclusions from pathology reports (2003-2012) describing carcinoids, (large cell) neuroendocrine carcinomas (NECs), and carcinomas with neuroendocrine features/differentiation were retrieved from the Dutch Pathology Registry by queries on location and diagnosis and screened for terminology. Cases with a nonpulmonary or unknown origin and small cell lung cancer were excluded. Diagnoses were clustered into subgroups and the retrieved terminology was compared with the 2015 World Health Organization (WHO) diagnoses. By means of an online questionnaire, interpretation of the non-WHO nomenclature retrieved from pathology reports was evaluated (by 35 physicians and 19 pathologists). A total of 3216 unique pathology report conclusions with 55 different pNET diagnoses (n = 3052) and 20 uncertain diagnoses (n = 164) were analyzed. Non-WHO nomenclature was used in 15% of diagnoses (n = 488). Diagnoses could be clustered into carcinoids (n = 1086), NEC (n = 1316), carcinomas with neuroendocrine features/differentiation (n = 624), and unspecified pNETs (n = 26). Non-WHO nomenclature within these clusters was found for 7% of carcinoids, 20% of NECs, 13% of carcinomas with neuroendocrine features/differentiation, and 100% of unspecified pNETs and was observed more often in conclusions regarding biopsy or cytological specimens (62% and 12%) compared with resection specimens (26%). Analysis of the questionnaire results revealed that 4 of 19 diagnoses based on non-WHO nomenclature were uniformly interpreted (>50% agreement) by physicians, as were 10 of 19 diagnoses by pathologists. In 15% of pNETs other than small cell lung cancer, a non-WHO nomenclature diagnosis was provided, more frequently on the basis of smaller specimens. The interpretation was different between physicians and

The present work describes the formulation and evaluation of the gastroretentive system of Itopride hydrochloride. In this research, we have formulated floating hydrogel-based microspheres employing calcium carbonate (CaCO(3)) as a gas forming agent dispersed in alginate matrix. In vitro characterizations such as drug content, particle size, and drug release were carried out. GI motility was determined by administration of charcoal meal to rats. Results demonstrated that prepared microspheres were spherical in shape with smooth surface, good loading efficiency, and excellent buoyancy. The gastro retentive dosage form of itiopride demonstrated significant antacid, anti-ulcer, and anti-GERD activity after 12 hours in comparison with the conventional dosage form.

Limited data exist regarding the psychosocial aspects of gastroesophageal reflux disease (GERD). Some GERD subgroups, such as functional heartburn and hypersensitive esophagus, might show different psychiatric comorbidities than others. We aimed to evaluate the psychiatric comorbidities of GERD subgroups using a cross-sectional design. A group of GERD patients at a tertiary outpatient clinic were evaluated via upper GIS (gastrointestinal system) endoscopy, esophageal manometry, and 24-h impedance-pH monitoring. Thirty-nine patients diagnosed with erosive reflux disease, 44 with non-erosive reflux disease, 20 with functional heartburn, 11 with hypersensitive esophagus, and 44 healthy controls participated. Psychiatric diagnoses were made using the Structured Clinical Interview for Diagnostics and Statistical Manual of Mental Disorders IV. Psychometric measurements of the patients were performed using the Somatosensory Amplification Scale, Beck Depression Inventory, State-Trait Anxiety Inventory, and Short-Form 36. Healthy controls were evaluated with the same psychometric scales except for the Short-Form 36. All of the GERD subgroups were significantly more depressed than the control group. Depressive disorders were significantly more prevalent in the functional heartburn group than in the non-erosive reflux disease and erosive reflux disease groups. The trait anxiety level of the functional heartburn group was significantly higher than those of the control and non-erosive reflux disease groups. The quality of life scores of the GERD subgroups were significantly lower than the population standards. Depressive disorders were frequently comorbid in the GERD subgroups studied (30-65 %). It is essential to consider the high prevalence rates of comorbid depression when managing GERD.

Studies of cell lines and of animal models of pancreatic cancer have raised a number of provocative questions about the nature and origins of human pancreatic cancer and have provided several leads into exciting new approaches for the treatment of this deadly cancer. In addition, clinicians with little or no contact with human pathology have challenged the way that pancreatic pathology is practiced, suggesting that “genetic signals” may be more accurate than today’s multi-modal approach to diagnoses. In this review we consider eight provocative issues in pancreas pathology, with an emphasis on “the evidence derived from man.” PMID:23060061

Gastroesophageal reflux disease and non-digestive tract diseases.

PubMed

Chen, Ying

2015-05-01

Over the past decade, incidence of gastroesophageal reflux disease (GERD) showed an increasing trend resulting from factors, including lifestyle and dietary habits; however, both etiology and pathological mechanisms remain controversial. GERD occurs as a result of a variety of mechanisms and there is no single factor. Symptoms of GERD are often non-typical, with a likelihood of being overlooked by non-gastroenterology professionals. Therefore, improving GERD awareness in non-gastroenterology practitioners, along with early diagnosis and treatment, provide potential benefit to clinicians and patients alike. Increasing evidence suggests GERD has specific connections with a variety of non-digestive tract conditions, may contribute an aggravating compounding effect on other diseases, prolong hospitalization, and increase subsequent medical costs. This review considers and emphasizes the association between GERD and non-digestive tract conditions, including atrial fibrillation, chronic obstructive pulmonary disease, primary pulmonary fibrosis and energy metabolism related to diet.

Gastroesophageal reflux disease (GERD) is associated with allograft dysfunction after lung transplantation (LTX). We attempted to identify outcomes in LTX recipients with clinical evidence of GERD. Retrospective review of 162 LTX recipients at our institution between January 1994 and June 2006 was performed. GERD was confirmed in symptomatic patients by esophagogastroduodenoscopy (EGD) and/or esophagography. Occurrence of biopsy-proven obliterative bronchiolitis (OB) and bronchiolitis obliterans syndrome (BOS) were analyzed. Kaplan-Meier analysis of survival and Cox proportional hazard analysis of risk factors were performed. GERD was diagnosed in 21 (13%) of patients, usually following LTX (71%). There was no difference in mean survival (1603 +/- 300 vs. 1422 +/- 131 days; log rank P > 0.05), or development of OB (5% vs. 6%, respectively; P > 0.05) in patients with GERD compared with patients without GERD. However, there was correlation between GERD and BOS (P = 0.01). Symptomatic GERD is increased following LTX. Patients with symptomatic GERD demonstrated an increased incidence of BOS, but survival was not affected in this study. More sensitive and specific diagnostic tools should be implemented in all LTX recipients to investigate the impact of symptomatic and silent GERD and thus improve outcomes after LTX.

Measurement of esophago-gastric junction (EGJ) cross-sectional area (CSA) and distensibility by an Endolumenal Functional Lumen Imaging Probe (EndoFLIP®) may distinguish between gastro-esophageal reflux disease (GERD) patients and healthy volunteers (HV). We aimed to assess the agreement of EndoFLIP® measurements with clinical and physiologic diagnosis of GERD. Twenty-one HV and 18 patients with typical GERD symptoms were studied. After gastroscopy, EGJ CSA, and distensibility were measured by EndoFLIP®. Forty-eight hour esophageal pH monitoring was then performed by a wireless system. The ability of EndoFLIP® to discriminate GERD patient and HVs was assessed. Planned secondary analysis then assessed whether EGJ CSA and distensibility were increased in individuals with pathologic acid exposure. Healthy volunteers were younger and had lower body mass index (BMI; both p < 0.001). Pathologic acid exposure was present in 3/21 (14%) HVs and 9/18 (50%) patients (p = 0.126). At 30 mL EndoFLIP® bag volume, EGJ CSA was higher (p = 0.058) and EGJ distensibility was lower (p = 0.020) in HVs than patients. Secondary analysis showed that EGJ measurements were similar in participants with and without pathologic acid exposure (CSA 98 mm² vs 107 mm²; p = 0.789, distensibility; p = 0.704). An inverse association between BMI and CSA (R² = 0.2758, p = 0.001) and distensibility (R² = 0.2005, p = 0.005) was present. Endolumenal Functional Lumen Imaging Probe is not useful for GERD diagnosis because EGJ CSA and distensibility do not distinguish between HVs and GERD patients defined by clinical presentation or pH measurement. This unexpected result may be due to an important, confounding interaction of obesity. © 2013 John Wiley & Sons Ltd.

Pathology is a medical subspecialty that practices the diagnosis of disease. Microscopic examination of tissue reveals information enabling the pathologist to render accurate diagnoses and to guide therapy. The basic process by which anatomic pathologists render diagnoses has remained relatively unchanged over the last century, yet advances in information technology now offer significant opportunities in image-based diagnostic and research applications. Pathology has lagged behind other healthcare practices such as radiology where digital adoption is widespread. As devices that generate whole slide images become more practical and affordable, practices will increasingly adopt this technology and eventually produce an explosion of data that will quickly eclipse the already vast quantities of radiology imaging data. These advances are accompanied by significant challenges for data management and storage, but they also introduce new opportunities to improve patient care by streamlining and standardizing diagnostic approaches and uncovering disease mechanisms. Computer-based image analysis is already available in commercial diagnostic systems, but further advances in image analysis algorithms are warranted in order to fully realize the benefits of digital pathology in medical discovery and patient care. In coming decades, pathology image analysis will extend beyond the streamlining of diagnostic workflows and minimizing interobserver variability and will begin to provide diagnostic assistance, identify therapeutic targets, and predict patient outcomes and therapeutic responses.

To investigate the relationship between pathological oropharyngeal (OP) acid exposure and esophageal motility in patients with extra-esophageal syndromes. In this prospective study we enrolled consecutive outpatients with extra-esophageal symptoms suspected to be related to gastroesophageal reflux disease (GERD). We enrolled only patients with a reflux symptom index (RSI) score-higher than 13 and with previous lung, allergy and ear, nose and throat evaluations excluding other specific diagnoses. All patients underwent 24-h OP pH-metry with the Dx probe and esophageal high-resolution manometry (HRM). Patients were divided into two groups on the basis of a normal or pathological pH-metric finding (Ryan Score) and all manometric characteristics of the two groups were compared. We examined 135 patients with chronic extra-esophageal syndromes. Fifty-one were considered eligible for the study. Of these, 42 decided to participate in the protocol. Patients were divided into two groups on the basis of normal or pathological OP acid exposure. All the HRM parameters were compared for the two groups. Significant differences were found in the median upper esophageal sphincter resting pressure (median 71 mmHg vs 126 mmHg, P = 0.004) and the median proximal contractile integral (median 215.5 cm•mmHg•s vs 313.5 cm•mmHg•s, P = 0.039), both being lower in the group with pathological OP acid exposure, and the number of contractions with small or large breaks, which were more frequent in the same group. This group also had a larger number of peristaltic contractions with breaks in the 20 mmHg isobaric contour (38.7% vs 15.38%, P < 0.0001). In patients with suspected GERD-related extra-esophageal syndromes pathological OP acid exposure was associated with weaker proximal esophageal motility.

AIM: To investigate the incidence of gastroesophageal reflux disease (GERD) and its related risk factors in Uygur and Han Chinese adult in Urumqi, China. METHODS: A population-based cross-sectional survey was undertaken in a total of 972 Uygur (684 male and 288 female) aged from 24 to 61 and 1023 Han Chinese (752 male and 271 female) aged from 23 to 63 years. All participants were recruited from the residents who visited hospital for health examination from November 2011 to May 2012. Each participant signed an informed consent and completed a GERD questionnaire (Gerd Q) and a lifestyle-food frequency questionnaire survey. Participants whose Gerd Q score was ≥ 8 and met one of the following requirements would be enrolled into this research: (1) being diagnosed with erosive esophagitis (EE) or Barrett’s esophagus (BE) by endoscopy; (2) negative manifestation under endoscopy (non-erosive reflux disease, NERD) with abnormal acid reflux revealed by 24-h esophageal pH monitoring; and (3) suffering from typical heartburn and regurgitation with positive result of proton pump inhibitor test. RESULTS: According to Gerd Q scoring criteria, 340 cases of Uygur and 286 cases of Han Chinese were defined as GERD. GERD incidence in Uygur was significantly higher than in Han Chinese (35% vs 28%, χ2 = 11.09, P < 0.005), Gerd Q score in Uygur was higher than in Han Chinese (7.85 ± 3.1 vs 7.15 ± 2.9, P < 0.005), and Gerd Q total score in Uygur male was higher than in female (8.15 ± 2.8 vs 6.85 ± 2.5, P < 0.005). According to normalized methods, 304 (31%) cases of Uygur were diagnosed with GERD, including 89 cases of EE, 185 cases of NERD and 30 cases of BE; 256 (25%) cases of Han Chinese were diagnosed with GERD, including 90 cases of EE, 140 cases of NERD and 26 cases of BE. GERD incidence in Uygur was significantly higher than in Han Chinese (31% vs 25%, χ2 = 9.34, P < 0.005) while the incidences were higher in males of both groups than in females (26% vs 5% in Uygur, χ2

Predictive analytics can provide valuable support to the effective management of pathology facilities. The introduction of new tests and technologies in anatomical pathology will increase the volume of specimens to be processed, as well as the complexity of pathology processes. In order for predictive analytics to address managerial challenges associated with the volume and complexity increases, it is important to pinpoint the areas where pathology managers would most benefit from predictive capabilities. We illustrate common issues in managing pathology facilities with an analysis of the surgical specimen process at the Department of Pathology and Laboratory Medicine (DPLM) at The Ottawa Hospital, which processes all surgical specimens for the Eastern Ontario Regional Laboratory Association. We then show how predictive analytics could be used to support management. Our proposed approach can be generalized beyond the DPLM, contributing to a more effective management of pathology facilities and in turn to quicker clinical diagnoses.

The objective of the study was to evaluate whether texture analysis using histogram and gray level co-occurrence matrix (GLCM) parameters can help clinicians diagnose lymphocytic thyroiditis (LT) and differentiate LT according to pathologic grade. The background thyroid pathology of 441 patients was classified into no evidence of LT, chronic LT (CLT), and Hashimoto's thyroiditis (HT). Histogram and GLCM parameters were extracted from the regions of interest on ultrasound. The diagnostic performances of the parameters for diagnosing and differentiating LT were calculated. Of the histogram and GLCM parameters, the mean on histogram had the highest Az (0.63) and VUS (0.303). As the degrees of LT increased, the mean decreased and the standard deviation and entropy increased. The mean on histogram from gray-scale ultrasound showed the best diagnostic performance as a single parameter in differentiating LT according to pathologic grade as well as in diagnosing LT.

Pathologists use diverse terminology when interpreting melanocytic neoplasms, potentially compromising quality of care. We sought to evaluate the Melanocytic Pathology Assessment Tool and Hierarchy for Diagnosis (MPATH-Dx) scheme, a 5-category classification system for melanocytic lesions. Participants (n = 16) of the 2013 International Melanoma Pathology Study Group Workshop provided independent case-level diagnoses and treatment suggestions for 48 melanocytic lesions. Individual diagnoses (including, when necessary, least and most severe diagnoses) were mapped to corresponding MPATH-Dx classes. Interrater agreement and correlation between MPATH-Dx categorization and treatment suggestions were evaluated. Most participants were board-certified dermatopathologists (n = 15), age 50 years or older (n = 12), male (n = 9), based in the United States (n = 11), and primary academic faculty (n = 14). Overall, participants generated 634 case-level diagnoses with treatment suggestions. Mean weighted kappa coefficients for diagnostic agreement after MPATH-Dx mapping (assuming least and most severe diagnoses, when necessary) were 0.70 (95% confidence interval 0.68-0.71) and 0.72 (95% confidence interval 0.71-0.73), respectively, whereas correlation between MPATH-Dx categorization and treatment suggestions was 0.91. This was a small sample size of experienced pathologists in a testing situation. Varying diagnostic nomenclature can be classified into a concise hierarchy using the MPATH-Dx scheme. Further research is needed to determine whether this classification system can facilitate diagnostic concordance in general pathology practice and improve patient care.

With changing indications for performing medical liver biopsies, we aimed to develop a tool to allow pathologists to evaluate the current usefulness, value and impact of their medical liver biopsy service. We designed and piloted a questionnaire-based clinico-pathological audit for medical liver biopsies. The audit tool was simple to implement and provided useful information about our service. Hepatologists felt that 96% of reports were clinically useful. 56% of biopsies confirmed clinical diagnoses, 46% helped differentiate between diagnoses and 42% were able to exclude possible diagnoses. 74% resulted in a change of management and 27% of liver biopsies resulted in a diagnosis which was not clinically suspected. We demonstrate the usefulness of an audit tool in providing evidence of the value of the liver pathology service in a large UK regional centre. Published by the BMJ Publishing Group Limited.

The aim of the study was a retrospective evaluation of 299 cases that were histopathologically diagnosed as cystic echinococcosis (CE) in the pathology laboratory of our hospital in a seven years period. All specimens sent to the laboratory were examined microscopically following macroscopic and hematoxylin eosin (H-E) staining. 299 cases were reviewed according to age, gender and organ affected by the cyst, more than one specimen of the same organ was evaluated once. Of the 299 cases, 44.5% (133) were male whereas 55.5% (166) of them were female. Additionally, %5 (15) of the cases were between 0-15 ages, %31.8 (95) of them were between 16-30 ages, %29.4 (88) of them were between 31-45 ages, % 24.4 (73) of them were between 46-60 ages and %9.4 (28) of them were older than 61. Cysts were mostly localized in liver, lungs and peritoneal cavity, %71.9 (215), %11.4 (34) and %4.7 (14) respectively. Demographic features of our cases were mostly in line with the previous literature. Because of the presence of atypical localized cases, during pathologic evaluation of all surgical cystic specimens, elements of this parasite should be searched and evaluated carefully.

Gastroesophageal reflux disease (GERD) is typically diagnosed based on symptoms of regurgitation and heartburn, although it may also manifest as asthma-like symptoms, laryngitis, or dental erosion. The purpose of this prospective, cross-sectional study was to assess the prevalence of dental erosion in people with GERD and to evaluate the association between GERD and dental erosion. The presence, severity, and pattern of dental erosion was assessed in 51 participants with GERD and 50 participants without GERD using the Smith and Knight tooth wear index. Medical, dietary, and dental histories were collected by questionnaire. Factors potentially related to dental erosion, including GERD, were evaluated by logistic regression. Dental erosion was observed in 31 (60.8%) participants with GERD and 14 (28%) participants without GERD. Bivariate analysis revealed that participants with GERD were more likely to experience dental erosion (crude odds ratio [cOR]: 2.74; 95% CI: 1.19, 6.32) than participants without GERD. Multivariate analysis also revealed that participants with GERD had a higher risk of dental erosion (adjusted odds ratio [aOR]: 3.97; 95% CI: 1.45, 10.89). Consumption of grains and legumes, the most frequently consumed foods in China, did not correlate with dental erosion. However, carbonated beverage consumption was significantly associated with GERD and dental erosion (aOR: 3.34; 95% CI: 1.01, 11.04; P=.04). GERD was positively correlated with dental erosion. Carbonated beverage consumption can increase the risk of both GERD and dental erosion. Copyright © 2016 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc.

Pathological predictive factors are the most important markers when selecting early breast cancer adjuvant therapy. In randomized clinical trials the variability in pathology report after central pathology review is noteworthy. We evaluated the discordance rate (DR) and inter-rater agreement between local and central histopathological report and the clinical implication on treatment decision. A retrospective analysis was conducted in a series of consecutive early breast cancer tumors diagnosed by local pathologists and subsequently reviewed at the Pathology Division of European Institute of Oncology. The inter-rater agreement (k) between local and central pathology was calculated for Ki-67, grading, hormone receptors (ER/PgR) and HER2/neu. The Bland-Altman plots were derived to determine discrepancies in Ki-67, ER and PgR. DR was calculated for ER/PgR and HER2. From 2007 to 2013, 187 pathology specimens from 10 Cancer Centers were reviewed. Substantial agreement was observed for ER (k0.612; 95% CI, 0538-0.686), PgR (k0.659; 95% CI, 0580-0.737), Ki-67 (k0.609; 95% CI, 0.534-0.684) and grading (k0.669; 95% CI, 0.569-0.769). Moderate agreement was found for HER2 (k0.546; 95% CI, 0444-0.649). DR was 9.5% (negativity to positivity) and 31.7% (positivity to negativity) for HER2 and 26.2% (negativity to positivity) and 12.5% (positivity to negativity) for ER/PgR. According to changes in Her2 and ER/PgR status, 23 (12.2%) and 33 (17.6%) systemic prescription were respectively modified. In our retrospective analysis, central pathological review has a significant impact in the decision-making process in early breast cancer, as shown in clinical trials. Further studies are warranted to confirm these provocative results. Copyright © 2016 Elsevier Ltd. All rights reserved.

Advanced lung disease is associated with gastroesophageal reflux disease (GERD). The thoracoabdominal pressure gradient (TAPG) facilitates gastroesophageal reflux, but the effects of TAPG on gastroesophageal reflux in patients with pulmonary disease have not been well defined. Patients diagnosed with end-stage lung disease are expected to have the most extreme derangement in respiratory mechanics. The aim of this study is to explore the relationship between TAPG and reflux in lung transplant (LTx) candidates. We reviewed LTx recipients who underwent pretransplant esophageal high-resolution manometry and a 24-hour pH study. Patients were excluded if they were undergoing redo LTx, had manometric hiatal hernia, or had previously undergone foregut surgery. TAPG was defined as the intra-abdominal pressure minus the intrathoracic pressure during inspiration. Adjusted TAPG was calculated by the TAPG minus the resting lower esophageal sphincter (LES) pressure (LESP). Twenty-two patients with normal esophageal function tests (i.e., normal esophageal motility with neither manometric hiatal hernia nor pathological reflux on 24-hour pH monitoring) were selected as the pulmonary disease-free control group. In total, 204 patients underwent LTx between January 2015 and December 2016. Of these, 77 patients met inclusion criteria. We compared patients with obstructive lung disease (OLD, n = 33; 42.9%) and those with restrictive lung disease (RLD, n = 42; 54.5%). 2/77 patients (2.6%) had pulmonary arterial hypertension. GERD was more common in the RLD group than in the OLD group (24.2% vs. 47.6%, P = 0.038). TAPG was similar between the OLD group and the controls (14.2 vs. 15.3 mmHg, P = 0.850); however, patients in the RLD group had significantly higher TAPG than the controls (24.4 vs. 15.3 mmHg, P = 0.002). Although TAPG was not correlated with GERD, the adjusted TAPG correlated with reflux in all 77 patients with end-stage lung disease (DeMeester score, rs = 0.256, P�

GERD is among the most common outpatient disease processes encountered by clinicians on a daily basis. This review provides insights about how to approach GERD in terms of disease management and treatment. Review articles were searched using PUBMED and MEDLINE using criteria that included English language articles published in the last 5 years concerning studies carried out only in humans. The key words used in the searches were GERD, PPI, and erosive esophagitis. Recommendations from the American College of Gastroenterology are also included in this manuscript. The search resulted in ∼260 articles. The manuscript brings together and presents the results of recent recommendations from professional societies and recently published review articles on GERD. GERD is one of the most common diagnoses made by gastroenterologists and primary care physicians. It is important to recognize the typical and atypical presentations of GERD. This paper helps primary care physicians understand the disease's pathophysiology, and when, how, and with what to treat GERD before referring patients to gastroenterologists or surgeons.

Chest radiographs and computed tomographic (CT) scans of the mediastinum were correlated with pathologic findings of the thymus following thymectomy in 57 patients with myasthenia gravis. Based on the patient's age and the overall morphology of the anterior mediastinum, CT scans were assigned one of four grades in an attempt to predict thymus pathologic findings. Using this grading, 14 of 16 cases of thymoma were suspected or definitely diagnosed. One of the two cases not diagnosed on CT was a microscopic tumor. There were no false-positive diagnoses in 11 cases graded as definitely thymoma. We conclude that thymoma can bemore » sensitively diagnosed in patients older than 40 years of age. However, thymoma cannot be predicted with a high level of confidence in patients younger than 40 because of the difficulty in differentiating normal thymus or hyperplasia from thymoma. Recommendations for the use of CT in the preoperative evaluation of myasthenic patients are presented.« less

Intermittent and on-demand use of proton pump inhibitors in the management of symptomatic gastroesophageal reflux disease.

PubMed

2003-03-01

The epidemic of gastroesophageal reflux disease (GERD) in industrialized nations is currently spreading to less-developed ones, with more than half of the patients having symptomatic or mild erosive GERD. The long-term management of GERD has been dominated by daily maintenance treatment with proton pump inhibitors (PPI) to prevent relapse. It is common, however, for many patients with mild disease and infrequent symptom relapses to use a PPI only when symptoms demand. Patients with symptomatic or mild erosive GERD are therefore ideal for on-demand or intermittent treatment. The efficacy of such a strategy of intermittent treatment, or treatment of symptoms on demand, has recently been evaluated in four randomized controlled studies. These trials demonstrate that such therapeutic strategies reduce symptoms, improve quality of life, and are cost effective. In clinical practice, the author has found these treatment strategies suitable for approximately 60% of newly diagnosed patients with GERD for the long-term management of symptomatic GERD of mild or moderate severity.

Oral manifestations in gastroesophageal reflux disease.

Many systemic diseases exert their influence on oral health. Among these, gastroesophageal reflux disease (GERD) is the most common. In this study, 100 patients who were previously diagnosed with GERD were examined following a 12-hour fast and evaluated in terms of the severity (grade) of the disease as well as any oral, dental, and/or salivary pH changes. Results found 11 patients with tooth erosion. These patients were older, and their average mean duration of GERD was longer in comparison to those without erosion. There was an inverse relationship between salivary pH and the GERD duration and grade of severity. As the GERD grade increased, the severity of tooth erosion increased. Patients with erosion also exhibited oral mucosal changes. Thus severe, long-term GERD was found to be potentially detrimental to oral soft tissues, dental structures, and salivary pH, whereas milder forms of the disease did not necessarily cause dental side effects.

Few studies have examined the incidence of complications from gastro-esophageal reflux disease (GERD) in children and adolescents in primary care. Here we aimed to describe the natural history of GERD in a pediatric population with no reflux esophagitis at initial diagnosis, assessing diagnoses of new esophageal complications and extra-esophageal conditions. We used The Health Improvement Network UK primary care database (which includes data on more than 2 million patients) to identify individuals aged 1-17 years with a first diagnosis of gastro-esophageal reflux or heartburn in the period 2000-2005, via a computerized search followed by a manual review of the patient records. This search identified 1242 individuals with an incident diagnosis of GERD but no record of esophagitis. This cohort was followed-up to detect new diagnoses of esophageal complications and extra-esophageal conditions. During a mean follow-up period of almost 4 years, 40 children and adolescents had a confirmed new diagnosis of reflux esophagitis (incidence: 10.9 per 1000 person-years). No cases of Barrett's esophagus, esophageal stricture or esophageal ulcer were reported. Individuals with GERD had double the risk of an extra-esophageal condition such as asthma, pneumonia, cough or chest pain compared with children and adolescents with no diagnosis of GERD. Children and adolescents with GERD may be at risk of developing reflux esophagitis and a range of other extra-esophageal conditions, but more severe esophageal complications are rare.

Gastroesophageal reflux disease (GERD) is a very common condition whose consequences of are localized not only in the esophagus; extra-esophageal involvement has frequently been reported. The aim of the study is to examine the incidence and pattern of dental erosion in GERD patients. A total of 50 patients were recruited in this study (control -25 and GERD -25). All participants diagnosed having GERD by the endoscopic examination by their gastroenterologist are included. The patients were examined for dental erosion and will be quantified using Basic erosive wear examination index. The results showed that the incidence of dental erosion was 88% as compared to 32% in the control group which was found to be statistically significant.

To assess values of 24-h esophageal pH-monitoring parameters with dual-channel probe (distal and proximal channel) in children suspected of gastroesophageal reflux disease (GERD). 264 children suspected of gastroesophageal reflux (GER) were enrolled in a study (mean age c=20.78+/-17.23 mo). The outcomes of this study, immunoallerrgological tests and positive result of oral food challenge test with a potentially noxious nutrient, enabled to qualify children into particular study groups. 32 (12.1%) infants (group 1) had physiological GER diagnosed. Pathological acid GER was confirmed in 138 (52.3%) children. Primary GER was diagnosed in 76 (28.8%) children (group 2) and GER secondary to allergy to cow milk protein and/or other food (CMA/FA) in 62 (23.5%) children (group 3). 32 (12.1%) of them had CMA/FA (group 4-reference group), and in remaining 62 (23.5%) children neither GER nor CMA/FA was confirmed (group 5). Mean values of pH monitoring parameters measured in distal and proximal channel were analyzed in individual groups. This analysis showed statistically significant differentiation of mean values in the case of: number of episodes of acid GER, episodes of acid GER lasting >5 min, duration of the longest episode of acid GER in both channels, acid GER index total and supine in proximal channel. Statistically significant differences of mean values among examined groups, especially between group 2 and 3 in the case of total acid GER index (only distal channel) were confirmed. 24-h esophageal pH monitoring confirmed pathological acid GER in 52.3% of children with typical and atypical symptoms of GERD. The similar pH-monitoring values obtained in group 2 and 3 confirm the necessity of implementation of differential diagnosis for primary vs secondary cause of GER.

Studies on the association between gastroesophageal reflux disease (GERD) and sleep apnea syndrome (SAS) have reported conflicting results, and attention has not been paid to the relationship between GERD and other sleep disorders. The aim of the study was to evaluate the relationship between GERD and various aspects of sleep disturbances. A total of 564 subjects who were referred to a sleep laboratory were enrolled in the study. They underwent nocturnal polysomnography (NPSG), and they were asked to complete a GERD questionnaire. The questionnaire consisted of 14 items, and included questions on seven reflux symptoms, namely, heartburn, acid regurgitation, chest pain, hoarseness, globus sensation, coughing and epigastric soreness. Subjects reporting heartburn or acid regurgitation at least once a week were classified as having GERD. Among 564 participants, 51 subjects (9.0%) were diagnosed as having GERD. GERD patients had higher scores in Beck depression inventory (p<.01), Epworth sleepiness scale (p=.03), Pittsburg sleep quality index (p<.01), more spontaneous arousals in NPSG, and more alcohol consumption than non-GERD patients. There was no association between presence of GERD, SAS-related variables, and body mass index (BMI). GERD was significantly associated with poor sleep quality (adjusted OR, 3.5; 95% CI, 1.3-9.3) and depressed mood (adjusted OR, 2.8; 95% CI, 1.5-5.3). Poor subjective sleep and depressive symptoms are associated with the presence of GERD with no association between SAS, BMI and GERD. In managing patients with GERD, psychiatric and sleep symptoms need to be evaluated and appropriately treated. © 2013.

Acute aortic regurgitation (AR) is an important finding associated with a wide variety of disease processes. Its timely diagnosis is of utmost importance. Delay in diagnosis could prove fatal. We describe a case of acute severe AR that was timely diagnosed using real time three-dimensional (3D) transesophageal echocardiogram (3D TEE). Not only did it diagnose but also the images obtained by 3D TEE clearly matched with the pathologic specimen. Using this sophisticated imaging modality that is mostly available at the tertiary centers helped in the timely diagnosis, which lead to the optimal management saving his life. Echocardiography and especially 3D TEE can diagnose AR very accurately. Surgical intervention is the definitive treatment but medical therapy is utilized to stabilize the patient initially.

Recent Advances in Noncardiac Chest Pain in Korea

2012-01-01

Gastroesophageal reflux disease (GERD) is the most common cause of noncardiac chest pain (NCCP) and is present in up to 60% of patients with NCCP in Western countries. In Korea, after a reasonable cardiac evaluation, GERD is reported to underlie 41% of NCCP cases. Typical reflux symptoms are frequent in Korean patients suffering from NCCP. Therefore, a careful history of the predominant symptoms, including heartburn and acid regurgitation, is relatively indicative of the GERD diagnosis in Korea. In Korea, in contrast to Western countries, patients aged 40 years and over who have been diagnosed with NCCP but who are without alarming features should undergo endoscopy to exclude gastric cancer or peptic ulcers because of the higher prevalence of peptic ulcer disease and gastric cancers in the region. In a primary care setting, in the absence of any alarming symptoms, a symptomatic response to a trial of a proton pump inhibitor (PPI) is sufficient for the presumptive diagnosis of GERD. In addition, the optimal duration of a PPI test may be at least 2 weeks, as GERD symptoms tend to be less frequent or atypical in Korean patients than in patients from Western countries. In patients diagnosed with GERD-related NCCP, long-term therapy (more than 2 months) with double the standard dose of a PPI is required to alleviate symptoms. Esophageal dysmotility is relatively uncommon, and pain modulators seem to offer significant improvement of chest pain control in non-GERD-related NCCP. Most traditionally available tricyclics or heterocyclics have many undesirable effects. Therefore, newer drugs with fewer side effects (for example, the serotonin - norepinephrine reuptake inhibitors) may be needed. PMID:22375165

Pediatric spine pathology poses a diagnostic challenge for radiologists. Acquired spine pathology often yields nonspecific signs and symptoms in children, especially in the younger age groups, and diagnostic delay can carry significant morbidity. This review is focused on some of the more common diagnostic dilemmas we face when attempting to evaluate and diagnose acquired pediatric spine anomalies in daily practice. An understanding of some of the key differentiating features of these disease processes in conjunction with pertinent history, physical exam, and advanced imaging techniques can indicate the correct diagnosis.

The advanced specialist diploma in ophthalmic pathology was jointly ratified by the Royal College of Pathologists and the Institute of Biomedical Science in 2008. It results in extended roles for suitably qualified Biomedical Scientists (BMSs) in ophthalmic pathology specimen dissection and histological reporting of selected specimens, specifically non-neoplastic corneas. This study aimed to examine the reporting of corneal histology by a BMS training towards this diploma in comparison with a Consultant Ophthalmic Pathologist. This report covers a non-interventional, prospective examination of BMS's diagnostic skills. After 6 months training, 50 consecutive corneal cases were reported by the BMS and the same case reported by the consultant ophthalmic pathologist. The BMS's diagnosis was compared with the final consultant's diagnosis. This exercise was then repeated after 24 months of training. After 6 months, the BMS's diagnoses matched the consultant diagnoses in 44/50 (88%) cases. After 24 months, the BMS's diagnoses matched the consultant diagnoses in 48/50 (96%) of cases. The results indicate that BMS's reporting of corneal histology is a real and safe possibility. Furthermore, it indicated deficiencies in BMS's diagnostic skills to inform further training/knowledge acquisition.

This pilot study was a comparison of dimensional models assessing personality traits and personality pathology in a clinical sample of adults diagnosed with ADHD and adults diagnosed with borderline personality disorder (BPD), and a nonclinical control sample of healthy adults. Personality traits were assessed using the NEO-Personality Inventory-Revised (NEO-PI-R) and dimensional personality pathology with the Dimensional Assessment of Personality Pathology-Basic Questionnaire (DAPP-BQ). Adults with ADHD and BPD produced higher Emotional Dysregulation/Neuroticism and Dissocial Behavior scores than controls. For the Extraversion/Inhibitedness scale, adults with BPD produced significantly lower scores than adults with ADHD and controls. On the Conscientiousness/Compulsivity domains, Conscientiousness scores were lower for both disorders, whereas low Compulsivity values were specific to adult ADHD. Our results suggest that patients with adult ADHD and BPD have distinguishable profiles of personality traits and personality pathology. © The Author(s) 2012.

A small angle (His angle) between the oesophagus and the fundus of the stomach is considered to act as flap valve and anti-reflux barrier. A wide angle results in dysfunction of the oesophagogastric junction and subsequently in gastroesophageal reflux disease (GERD). Here, we used real-time magnetic resonance imaging (MRI) at 50 ms resolution (20 frames per second) in 12 volunteers and 12 patients with GERD to assess transport of pineapple juice through the oesophagogastric junction and reflux during Valsalva. We found that the intra-abdominal part of the oesophagus was bended towards the left side resulting in an angle of 75.3 ± 17.4, which was significantly larger during Valsava (P = 0.017). Reflux and several underlying pathologies were detected in 11 out of 12 patients. Our data visualize oesophagogastric junction physiology and disprove the flap valve hypothesis. Further, non-invasive real-time MRI has considerable potential for the diagnosis of causative pathologies leading to GERD. PMID:26175205

Evaluation of a Diagnostic Encyclopedia Workstation for ovarian pathology.

The Diagnostic Encyclopedia Workstation (DEW) is a computer system that provides completely integrated pictorial and textual information as reference knowledge in the field of ovarian pathology. The textual component comprises information per diagnosis such as descriptions of macroscopic and microscopic images, clinical signs, and prognosis. In addition, the system offers lists of differential diagnoses and criteria to differentiate among lists of differential diagnoses and criteria to differentiate among them. The present study evaluates to what extent the system influences the diagnostic process in efficiency and outcome. Therefore, two groups of six pathologists each, covering a wide spectrum of experience in ovarian pathology, participated in the evaluation of the DEW. The quality of the resulting diagnoses was statistically analyzed with the Wilcoxon rank sum test with respect to five different viewpoints: classification, morphology, clinical consequences, duration of diagnostic process, and consensus among the participants. The results are discussed and it is concluded that classification and morphology showed better results when books were used. The evaluation experiment was, however, very rigid and negatively biased with respect to the DEW system. Positive aspects of the encyclopedia are the easy access to diagnostic and differential diagnostic information and the large set of illustrations. Insight is acquired with respect to existing bottlenecks and how they may be overcome.

There are limited data in the literature related to concomitant genital or extra-genital organ pathologies in patients with borderline ovarian tumors (BOTs). The aim of this study was to evaluate our experience with 183 patients to draw attention to the accompanying organ pathologies with BOTs. One hundred eighty-three patients with BOTs, diagnosed and/or treated in our center between January of 2000 and March of 2013 were evaluated retrospectively. Data related to age, tumor histology, lesion side, disease stage, accompanying incidental ipsilateral and/or contralateral ovarian pathologies, treatment approaches, and follow-up periods were investigated. Incidental gynecologic and non-gynecologic concomitant organ pathologies were also recorded. The mean age at diagnosis was 40.6 years (range: 17-78). Ninety- five patients (51%) were ≤40 years. A hundred and forty-seven patients (80%) were at stage IA of the disease. The most common type of BOT was serous in histology. Non-invasive tumor implants were diagnosed in 4% and uterine involvement was found 2% among patients who underwent hysterectomies. There were 12 patients with positive peritoneal washings. Only 17 and 84 patients respectively had concomitant ipsilateral and concomitant contralateral incidental ovarian pathologies. The most common type of uterine, appendicular and omental pathologies were chronic cervicitis, lymphoid hyperplasia and chronic inflammatory reaction. According to our findings most of accompanying pathologies for BOT are benign in nature. Nevertheless, there were additional malignant diseases necessitating further therapy. We emphasize the importance of the evaluation of all abdominal organs during surgery.

New technology has considerably advanced the diagnosis of small-bowel pathology. However, its significance in clinical algorithms has not yet been fully assessed. The aim of the present analysis was to compare the diagnostic utility and yield of video-capsule enteroscopy (VCE) to that of magnetic resonance imaging (MRI) in patients with suspected or established Crohn's disease (Group I), obscure gastrointestinal blood loss (Group II), or suspected tumors (Group III). Forty-six out of 182 patients who underwent both modalities were included: 21 in Group I, 20 in Group II, and five in Group III. Pathology was assessed in three predetermined sections of the small bowel (upper, middle, and lower). The McNemar and Wilcoxon tests were used for statistical analysis. In Group I, lesions were found by VCE in nine of the 21 patients and by MRI in six. In five patients, both modalities showed pathology. In Group II, pathological changes were detected in 11 of the 20 patients by VCE and in eight patients by MRI. In five cases, pathology was found with both modalities. In Group III, neither modality showed small-bowel pathology. For the patient groups combined, diagnostic yield was 43% with VCE and 30% with MRI. The diagnostic yield of VCE was superior to that of MRI in the upper small bowel in both Groups I and II. VCE is superior to MRI for the detection of lesions related to Crohn's disease or obscure gastrointestinal bleeding in the upper small bowel.

The Penn State Worry Questionnaire (PSWQ) was administered to 123 outpatients with principal diagnoses of generalized anxiety disorder (GAD), social anxiety disorder (SAD), panic disorder with agoraphobia, and panic disorder without agoraphobia (PD) to examine the specificity of pathological worry for GAD. The mean PSWQ scores in patients with GAD and SAD were significantly higher than the mean PSWQ scores in patients with PD, while not differing significantly in the subgroups without any co-occurring depressive or anxiety disorders. Patients with any co-occurring depressive or anxiety disorder scored significantly higher on the PSWQ. In a logistic regression analysis, high PSWQ scores independently predicted only GAD and SAD diagnoses. The study suggests that pathological worry is specific not only for GAD, and indicates that a significant relationship exists between pathological worry, GAD and SAD, and that depressive and anxiety disorders co-occurrence increases levels of pathological worry in patients with anxiety disorders.

The aim of this study was to analyse the impact of hiatal hernia repair (HHR) on gastro-oesophageal reflux disease (GERD) in morbidly obese patients with hiatus hernia undergoing laparoscopic sleeve gastrectomy (LSG). It is a retrospective study involving ten morbidly obese patients with large hiatus hernia diagnosed on pre-operative endoscopy who underwent LSG and simultaneous HHR. The patients were assessed for symptoms of GERD using a Severity symptom score (SS) questionnaire and anti-reflux medications. Of the ten patients, five patients had GERD preoperatively. At the mean follow-up of 11.70 ± 6.07 months after surgery, four patients (80%) showed complete resolution while one patient complained of persistence of symptoms. Endoscopy in this patient revealed resolution of esophagitis indicating that the persistent symptoms were not attributable to reflux. The other five patients without GERD remained free of any symptom attributable to GERD. Thus, in all ten patients, repair of hiatal hernia (HH) during LSG led to either resolution of GERD or prevented any new onset symptom related to GER. In morbidly obese patients with HH with or without GERD undergoing LSG, repair of the hiatus hernia helps in amelioration of GERD and prevents any new onset GER. Thus, the presence of HH should not be considered as a contraindication for LSG.

It is not yet clear if laparoscopic sleeve gastrectomy (LSG) causes newly onset gastroesophageal reflux (GERD) or worsens already existing GERD. This is due to the absence of prospective studies using objective assessment measures of GERD such as pH monitoring. Our study aims at assessing GERD 1-year post-LSG procedure for obesity. Twelve asymptomatic obese patients were studied prospectively by using 24-h multichannel intraluminal impedance-pHmetry (MIIpH) pre- and 12 months post-LSG. Of patients' 1-year post-LSG, 83.33 % of patients' suffer from GERD (either newly onset or worsening of already existing) as indicated by abnormal DeMeester score. Mean DeMeester score 1-year post LSG was 47, almost 2.5 times higher than the preoperative score (p = 0.072). The percentage of total time with pH lower than four was statistically significant higher postoperatively (13.27 % vs 3.87 %, p = 0.048). This study is one of the few assessing GERD post-LSG by using 24-h MIIpH. The majority of patients suffer from GERD 12 months postoperatively, implying that close postoperative monitor for GERD with the use of pH testing and upper gastrointestinal endoscopy in order to early diagnose GERD and identify possible mucosal injury and also a prophylactic proton pump inhibitor use may be of great importance.

Gastroesophageal reflux disease (GERD) and Barrett's Esophagus (BE), which are prevalent in the World Trade Center (WTC) exposed and general populations, negatively impact quality of life and cost of healthcare. GERD, a risk factor of BE, is linked to obstructive airways disease (OAD). We aim to identify serum biomarkers of GERD/BE, and assess the respiratory and clinical phenotype of a longitudinal cohort of never-smoking, male, WTC-exposed rescue workers presenting with pulmonary symptoms. Biomarkers collected soon after WTC-exposure were evaluated in optimized predictive models of GERD/BE. In the WTC-exposed cohort, the prevalence of BE is at least 6 times higher than in the general population. GERD/BE cases had similar lung function, D LCO , bronchodilator response and long-acting β-agonist use compared to controls. In confounder-adjusted regression models, TNF-α ≥ 6 pg/mL predicted both GERD and BE. GERD was also predicted by C-peptide ≥ 360 pg/mL, while BE was predicted by fractalkine ≥ 250 pg/mL and IP-10 ≥ 290 pg/mL. Finally, participants with GERD had significantly increased use of short-acting β-agonist compared to controls. Overall, biomarkers sampled prior to GERD/BE presentation showed strong predictive abilities of disease development. This study frames future investigations to further our understanding of aerodigestive pathology due to particulate matter exposure.

Data are limited regarding the role of proteinase-activated receptor-2 (PAR-2) in the esophageal mucosa in gastroesophageal reflux disease (GERD) patients. Our aim was to study PAR-2 expression and its relationship with different GERD-related clinical and pathologic parameters. Histomorphologic alterations in eosophageal mucosa in nonerosive reflux disease (NERD) and erosive reflux disease (ERD) were also, evaluated. Endoscopic biopsies of the esophageal mucosa were obtained from 94 GERD patients and 20 participants for histopathologic analysis and PAR-2 immunohistochemical staining. The present study demonstrated significantly higher PAR-2 expression in GERD patients compared with control, whereas no significant differences were seen between NERD and ERD groups. PAR-2 expression significantly correlated with histologic score (r=0.572, P<0.001) and severity of heartburn (r=0.541, P<0.001). PAR-2 expression was significantly associated with basal cell hyperplasia, and dilated intercellular spaces and inflammatory cell count (P<0.05). Histologic analysis revealed GERD-related histomorphologic alterations in the esophageal mucosa of GERD patients with significant differences (P<0.05) among groups. Total histologic score was significantly correlated with heartburn (r=0.299, P=0.025) and endoscopic severity (r=0.359, P=0.027) in NERD and ERD patients, respectively. Taken together, this study provides evidence for the major role of PAR-2 in the pathogenesis of GERD and GERD-associated mucosal alterations.

None of current diagnostic methods has been proven to be a reliable tool for gastro-esophageal reflux disease (GERD). Pepsin in saliva has been proposed as a promising diagnostic biomarker for gastro-esophageal reflux. We aimed to determine the diagnostic value of salivary pepsin detection for GERD. Two hundred and fifty patients with symptoms suggestive of GERD and 35 asymptomatic healthy volunteers provided saliva on morning waking, after lunch and dinner for pepsin determination using the Peptest lateral flow device. All patients underwent 24-h multichannel intraluminal impedance pH (24-h MII-pH) monitoring and upper gastrointestinal endoscopy. Based on 24-h MII-pH and endoscopy study, patients were defined as GERD (abnormal MII-pH results and/or reflux esophagitis) and non-GERD otherwise. Patients with GERD had a higher prevalence of pepsin in saliva and higher pepsin concentration than patients with non-GERD and healthy controls (P < 0.001 for all). The pepsin test had a sensitivity of 73% and a specificity of 88.3% for diagnosing GERD using the optimal cut-off value of 76 ng/mL. Postprandial saliva samples collected when the symptoms occurred had a more powerful ability to identify GERD. Salivary pepsin test had moderate diagnostic value for GERD. It may be a promising tool to replace the use of currently invasive tools with advantages of non-invasive, easy to perform and cost effective.

Whilst studies have consistently identified early symptom reduction as an important predictor of treatment outcome, the impact of early change on common comorbid features has not been investigated. This study of CBT for eating disorders explored patterns of early change in eating pathology and longer-term change in personality pathology, anxiety and depression. It also explored the impact of early change in eating pathology on overall change in personality pathology, anxiety and depression. Participants were 179 adults diagnosed with eating disorders who were offered a course of CBT in an out-patient community eating disorders service in the UK. Patients completed a measure of eating disorder psychopathology at the start of treatment and following the 6th session. They also completed measures of personality disorder cognitions, anxiety and depression at the start and end of treatment. There were significant changes in eating pathology over the first six sessions of treatment. Significant improvements were also seen in personality disorder pathology, anxiety and depression by the end of therapy. Effect sizes were medium to large for both completer and intention to treat analyses. Early changes in eating pathology were associated with later changes in common comorbid features, with early reduction in restraint being a key predictor. These findings demonstrate that early symptom change can be achieved in CBT for eating disorders when delivered in routine clinical practice. Such change has long-term benefits that go beyond the domain of eating pathology, enhancing change in personality pathology, anxiety and depression. Copyright © 2015 Elsevier Ltd.

Hyperspectral imaging (HSI) is an emerging technology for medical diagnosis. This research work presents a proof-of-concept on the use of HSI data to automatically detect human brain tumor tissue in pathological slides. The samples, consisting of hyperspectral cubes collected from 400 nm to 1000 nm, were acquired from ten different patients diagnosed with high-grade glioma. Based on the diagnosis provided by pathologists, a spectral library of normal and tumor tissues was created and processed using three different supervised classification algorithms. Results prove that HSI is a suitable technique to automatically detect high-grade tumors from pathological slides. PMID:29552415

We report on the results of using the optical coherence tomography (OCT) as one of the diagnostic methods at the Department of Gynecology of the Nizhny Novgorod Regional Hospital. An endoscopic OCT device adjusted for gynecological examinations with colposcopy, hysteroscopy and laparoscopy has been developed at the Institute of Applied Physics. It provides clinicians with sharp (up to 15 - 20 micron resolution) images of 1.5 mm thick superficial mucosa layers in the female genital tract, that are recorded at the 0.83 micron wavelength with approximately 1 frame/second rate for a 200 X 200 pixel image. Data obtained during examination of more than 100 patients demonstrate the capability of OCT in estimation of structural alterations in organs, connected with different types of pathologies and functional states of the female genital system. We present first results of OCT application to assess the adequacy of cervical pathologies treatment (electro-, laser surgery and cryotherapy) and to control the healing process.

Gastroesophageal reflux disease (GERD) is a common chronic gastrointestinal tract disease. The incidence is higher in Asian and Arab countries. In Saudi Arabia, there are few studies that have assessed the prevalence of GERD among some cities' communities. Hence, this study aims to study the prevalence of GERD among the general population of Saudi Arabia. A cross-sectional study was designed to determine the prevalence of GERD among the community of Saudi Arabia. The sample was randomly gathered through self-administered validated GERD questionnaire (GerdQ) to diagnose GERD, during the period from November to December 2016. The sociodemographic data was assessed for all participants. The data were analysed using Statistical Package for Social Sciences version 21.0 (SPSS); the t -test was used to assess the association of GERD and sociodemographic data. The sample was comprised of 2,043 participants. Female and male were 51.8% and 48.2%, respectively. Mean age was 29.6 years with the standard deviation of 10.5 years. The GERD prevalence was 28.7%. It was found statistically significant among divorced/widow (34.9%, P = 0.003). In contrast, there was no association between GERD's prevalence and gender, age, residence status, education level, occupation, and blood group (P > 0.05). The prevalence of GERD among Saudi population is higher than that in Western countries and East Asia. It affects divorced/widow, obese and those with a sedentary lifestyle. It is advocated that national programs and educational campaigns for prevention of this disease and its complications should be established.

Studies have shown that chronic inflammation may play a vital role in the pathophysiology of both gastroesophageal reflux disease (GERD) and bipolar disorder. Among patients with GERD, the risk of bipolar disorder has not been well characterized. We explored the relationship between GERD and the subsequent development of bipolar disorder, and examined the risk factors for bipolar disorder in patients with GERD. We identified patients who were diagnosed with GERD in the Taiwan National Health Insurance Research Database. A comparison cohort without GERD was matched according to age, sex, and comorbidities. The occurrence of bipolar disorder was evaluated in both cohorts based on diagnosis and the prescription of medications. The GERD cohort consisted of 21,674 patients, and the comparison cohort consisted of 21,674 matched control patients without GERD. The incidence of bipolar disorder (incidence rate ratio [IRR] 2.29, 95% confidence interval [CI] 1.58-3.36, P<.001) was higher among GERD patients than among comparison cohort. Multivariate, matched regression models showed that the female sex (hazard ratio [HR] 1.78, 95% CI 1.76-2.74, P = .008), being younger than 60 years old (HR 2.35, 95% CI 1.33-4.16, P = .003), and alcohol use disorder (HR 4.89, 95% CI 3.06-7.84, P = .004) were independent risk factors for the development of bipolar disorder among GERD patients. GERD may increase the risk of developing bipolar disorder. Based on our data, we suggest that attention should be focused on female patients younger than 60 years, and patients with alcohol use disorder, following a GERD diagnosis.

Integrating pathology and radiology disciplines: an emerging opportunity?

PubMed Central

2012-01-01

Pathology and radiology form the core of cancer diagnosis, yet the workflows of both specialties remain ad hoc and occur in separate "silos," with no direct linkage between their case accessioning and/or reporting systems, even when both departments belong to the same host institution. Because both radiologists' and pathologists' data are essential to making correct diagnoses and appropriate patient management and treatment decisions, this isolation of radiology and pathology workflows can be detrimental to the quality and outcomes of patient care. These detrimental effects underscore the need for pathology and radiology workflow integration and for systems that facilitate the synthesis of all data produced by both specialties. With the enormous technological advances currently occurring in both fields, the opportunity has emerged to develop an integrated diagnostic reporting system that supports both specialties and, therefore, improves the overall quality of patient care.

This study aimed to investigate the prevalence of the overlap between gastroesophageal reflux disease (GERD) and functional bowel disorders (FBD) in the general population in rural areas in China. A population-based cross-sectional study was conducted in six villages in Nanmazhuang area in Lankao County (Henan Province, China) from December 2010 to October 2011. The GERD questionnaire (GerdQ) and Rome III criteria were used for the diagnosis of GERD and FBD and to determine the prevalence of GERD-FBD overlap. The response rate to the questionnaires of the patients was 91.5%. In all, 2950 of 3700 residents with a mean age of 42.4 ± 16.8 years were included. Among them, 4.8% were diagnosed with GERD and 4.6% with FBD. The proportion of respondents with FBD was significantly higher in the GERD group than that in the non-GERD group (25.53% vs 3.60%, P < 0.05). The prevalence of GERD in the FBD group was significantly higher than that in the non-FBD group (26.28% vs 3.73%, P < 0.05). The prevalence of GERD-FBD overlap in the general rural population was 1.22%. Logistic regression analysis indicated that anxiety was an independent predictor for the GERD-FBD overlap in GERD and FBD (odds ratio [OR] 1.05, 95% confidence interval [CI] 1.02-1.09 and OR 1.06, 95% CI 1.02-1.10, respectively). GERD-FBD overlap is more common than expected by chance in the general rural population, and anxiety is significantly related to the overlap. © 2015 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

New Trends of Emerging Technologies in Digital Pathology.

The future paradigm of pathology will be digital. Instead of conventional microscopy, a pathologist will perform a diagnosis through interacting with images on computer screens and performing quantitative analysis. The fourth generation of virtual slide telepathology systems, so-called virtual microscopy and whole-slide imaging (WSI), has allowed for the storage and fast dissemination of image data in pathology and other biomedical areas. These novel digital imaging modalities encompass high-resolution scanning of tissue slides and derived technologies, including automatic digitization and computational processing of whole microscopic slides. Moreover, automated image analysis with WSI can extract specific diagnostic features of diseases and quantify individual components of these features to support diagnoses and provide informative clinical measures of disease. Therefore, the challenge is to apply information technology and image analysis methods to exploit the new and emerging digital pathology technologies effectively in order to process and model all the data and information contained in WSI. The final objective is to support the complex workflow from specimen receipt to anatomic pathology report transmission, that is, to improve diagnosis both in terms of pathologists' efficiency and with new information. This article reviews the main concerns about and novel methods of digital pathology discussed at the latest workshop in the field carried out within the European project AIDPATH (Academia and Industry Collaboration for Digital Pathology). © 2016 S.

Cervical cancer remains one of the most significant problem in oncogynecology. It tends towards treatment approaches that provide termination of pathological processes along with preservation of the patient's life quality. There is a need in earlier and more accurate diagnosis of pathological states, objective assessment of physiological processes, and adequate monitoring of the course of treatment. In our previous publications we have reported unique capabilities of the Optical Coherence Tomography (OCT) to image in vivo the mucosa structure of the cervix and to monitor various physiological and pathological alterations. In this report, we present results of OCT application to diagnose different stages of cervical cancer and to control its treatment at early stages. We have performed OCT-colposcopy in 11 female patients with cervical cancer to derive OCT criteria of this disease, to provide exact demarcation of a pathological area, and to determine a real size of a tumor. We have found that, in general, borders of a tumor, defined visually and detected with OCT by violation of the basement membrane in exocervix, do not coincide. The mismatch depends on a stage of cancer and can be as much as several millimeters. This information is especially important for evaluation of linear dimension of tumors with 3 - 5 mm invasion and also for differential diagnosis between the T1 and T2 stages with cancer extension onto vagina.

Gastroesophageal reflux disease (GERD) is a gastrointestinal disorder in which stomach acids are chronically regurgitated into the esophagus and oral cavity. Continual exposure of the teeth to these acids can cause severe tooth wear. Dentists are often the first healthcare professionals to diagnose dental erosion in patients with GERD. This article presents a case report of a 27-year-old male smoker with tooth wear and dentin sensitivity caused by GERD associated with bruxism. After diagnosis, a multidisciplinary treatment plan was established. The initial treatment approach consisted of medical follow-up with counseling on dietary and smoking habits, as well as management of the gastric disorders with medication. GERD management and the dental treatment performed for the eroded dentition are described, including diagnosis, treatment planning, and restorative therapy.

The prevalence of oral and maxillofacial pathology has not previously been reported in the Australian paediatric population. This study aimed to audit a large pathology service to provide insight into the prevalence of oral and maxillofacial pathology. Written records of a major Australian oral pathology service were imported into an electronic database. Age, gender and histological diagnosis were assessed. Prevalence of histological diagnoses as a percentage of the major diagnostic categories and of the whole sample were calculated, as well as gender predilections and mean age of presentation of disease. A total of 1305 oral pathology specimens, collected from paediatric patients aged 16 and under were included in the analysis. The most common pathology was dental pathology (24.4%), followed by odontogenic cysts (18.5%) and mucosal pathology (17.0%). The most frequently encountered lesion was the dentigerous cyst (9.4%), followed by fibrous hyperplasia (8.3%), radicular cyst (5.2%) and chronic periapical granuloma (5.2%). In the paediatric population, dental pathology and specifically, the dentigerous cyst is the most common pathology type sent for histopathology, suggesting a high prevalence of pathology of dental origin occurring in Australian children. © 2014 Australian Dental Association.

To compare long-term occurrence of gastroesophageal reflux disease (GERD) between two different types of peroral endoscopic myotomy (POEM) for achalasia. We included all patients with achalasia who underwent POEM at our hospital from August 2011 to October 2012 and had complete GERD evaluation with ≥ 3 years of follow-up. They were divided into circular or full-thickness myotomy groups according to the depth of myotomy. Demographics, Eckardt score, manometry results, 24-h pH monitoring, and GERD symptoms were recorded and compared between the two groups. We studied 56 patients (32 circular myotomy and 24 full-thickness myotomy) with complete GERD evaluation. There was no significant difference between the two groups in terms of treatment success (defined as Eckardt score ≤ 3), postoperative Eckardt score, mean basal lower esophageal sphincter pressure, and 4-s integrated relaxation pressure (4sIRP). Postoperative abnormal esophageal acid exposure was found in 25 patients (44.6%). A total of 13 patients (23.2%) had GERD symptoms and 12 had esophagitis (21.4%). Clinically relevant GERD (abnormal esophageal acid exposure associated with GERD symptoms and/or esophagitis) was diagnosed in 13 patients (23.2%). Multivariate analysis revealed that full-thickness myotomy and low level of postoperative 4sIRP were predictive factors for clinically relevant GERD. Efficacy and manometry are comparable between achalasia patients treated with circular or full-thickness myotomy. But patients with full-thickness myotomy and low postoperative 4sIRP have more GERD.

Gastroesophageal reflux disease in COPD: links and risks.

PubMed

Lee, Annemarie L; Goldstein, Roger S

2015-01-01

COPD is a long-term condition associated with considerable disability with a clinical course characterized by episodes of worsening respiratory signs and symptoms associated with exacerbations. Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal conditions in the general population and has emerged as a comorbidity of COPD. GERD may be diagnosed by both symptomatic approaches (including both typical and atypical symptoms) and objective measurements. Based on a mix of diagnostic approaches, the prevalence of GERD in COPD ranges from 17% to 78%. Although GERD is usually confined to the lower esophagus in some individuals, it may be associated with pulmonary microaspiration of gastric contents. Possible mechanisms that may contribute to GERD in COPD originate from gastroesophageal dysfunction, including altered pressure in the lower esophageal sphincter (which normally protect against GERD) and changes in esophageal motility. Proposed respiratory contributions to the development of GERD include respiratory medications that may alter esophageal sphincter tone and changes in respiratory mechanics, with increased lung hyperinflation compromising the antireflux barrier. Although the specific cause and effect relationship between GERD and COPD has not been fully elucidated, GERD may influence lung disease severity and has been identified as a significant predictor of acute exacerbations of COPD. Further clinical effects could include a poorer health-related quality of life and an increased cost in health care, although these factors require further clarification. There are both medical and surgical options available for the treatment of GERD in COPD and while extensive studies in this population have not been undertaken, this comorbidity may be amenable to treatment.

The aim of this study was to evaluate and compare the area, perimeter, and form (D factor and fractal dimension) of the dental wear among bruxist and nonbruxist children with mixed dentition in order to determine if the dental wear may be used as criteria to diagnose bruxism. The children were 8 to 11 years old and were classified as bruxist or nonbruxist, according to anxiety level and temporomandibular disorders. Dental casts of the upper arch were obtained for the bruxist (n = 24) and the control (n = 29) group. The dental wear was measured in digital format and processed automatically. The complete and pathological dental wear was compared between the two groups, using the Student's t-test and Mann-Whitney test. Statistically significant differences were observed between the two groups, with a higher area, perimeter, and more irregular form of the pathological dental wear among the bruxist group. Regarding complete dental wear, differences were only significant for the D factor (an un-dimensional quantitative parameter which produces a relation between the area and the perimeter of an object). Digital imaging of dental wear may be used as criteria to diagnose bruxism in children with mixed dentition after making an analysis of the area, perimeter, and irregularity of the form of pathological dental wear.

A randomized controlled trial (RCT) investigated patients with gastroesophageal reflux disease (GERD) who were stable and symptomatically controlled with long-term medical therapy to compare ongoing optimized medical therapy with laparoscopic Nissen fundoplication (LNF). Of the 180 patients eligible for randomization, 104 gave informed consent, and 3 withdrew from the study immediately after randomization. The patients randomized to medical therapy received optimized treatment with proton pump inhibitors (PPIs) using a standardized management protocol based on best evidence and published guidelines. The surgical patients underwent LNF by one of four surgeons using a previously published technique. The patients underwent symptom evaluation using the GERD symptom scale (GERSS) and the global visual analog scale (VAS) for overall symptom control. They had 24-h esophageal pH monitoring at baseline and after 3 years. The medical patients were evaluated receiving PPI, and the surgical patients were evaluated not receiving PPI. For the 3-year follow-up assessment, 93 patients were available. At 3 years, surgery was associated with more heartburn-free days, showing a mean difference of -1.35 days per week (p = 0.0077) and a lower VAS score (p = 0.0093) than medical management. Surgical patients reported improved quality of life on the general health subscore of the Medical Outcomes Survey Short Form 36 (SF-36) at 3 years, with a mean difference of -12.19 (p = 0.0124). The groups did not differ significantly in terms of GERSS or acid exposure on 24-h esophageal pH monitoring at 3 years. There were six treatment failures (11.8%) in the surgical group and eight treatment failures (16%) in the medical group by 3 years. For patients whose GERD symptoms are stable and controlled with PPI, continuing medical therapy and laparoscopic antireflux surgery are equally effective, although surgery may result in better symptom control and quality of life.

Whole slide imaging (WSI), or “virtual” microscopy, involves the scanning (digitization) of glass slides to produce “digital slides”. WSI has been advocated for diagnostic, educational and research purposes. When used for remote frozen section diagnosis, WSI requires a thorough implementation period coupled with trained support personnel. Adoption of WSI for rendering pathologic diagnoses on a routine basis has been shown to be successful in only a few “niche” applications. Wider adoption will most likely require full integration with the laboratory information system, continuous automated scanning, high-bandwidth connectivity, massive storage capacity, and more intuitive user interfaces. Nevertheless, WSI has been reported to enhance specific pathology practices, such as scanning slides received in consultation or of legal cases, of slides to be used for patient care conferences, for quality assurance purposes, to retain records of slides to be sent out or destroyed by ancillary testing, and for performing digital image analysis. In addition to technical issues, regulatory and validation requirements related to WSI have yet to be adequately addressed. Although limited validation studies have been published using WSI there are currently no standard guidelines for validating WSI for diagnostic use in the clinical laboratory. This review addresses the current status of WSI in pathology related to regulation and validation, the provision of remote and routine pathologic diagnoses, educational uses, implementation issues, and the cost-benefit analysis of adopting WSI in routine clinical practice.

Increased levels of anxiety and depression have been associated with esophageal hyperalgesia and an increased risk of gastroesophageal reflux disease (GERD). We investigated the effects of anxiety and depression on GERD symptoms and the perception of reflux episodes in a well-characterized group of patients. We performed a prospective study of 225 consecutive patients who had symptoms of GERD evaluated. Patients underwent ambulatory 24-hour pH impedance monitoring, and levels of anxiety and depression were assessed using the Hospital Anxiety and Depression Scale. GERD was diagnosed in 147 patients (78 patients had functional heartburn); 36 patients were hypersensitive to gastroesophageal reflux. Among patients with GERD, increased levels of anxiety were associated with more severe retrosternal pain and retrosternal burning. Furthermore, increased levels of anxiety and depression each were associated with lower scores of the mental component of quality of life questionnaire. Levels of anxiety or depression were not associated with the number of reflux symptoms reported during 24-hour pH impedance monitoring or with the number of symptoms associated with a reflux event. Among GERD patients with hypersensitivity to reflux, levels of anxiety and depression and decreases in quality of life were similar to those of other patients with GERD. Patients with functional heartburn had higher levels of anxiety than patients with GERD. In patients with GERD, increased levels of anxiety are associated with increased severity of retrosternal pain and heartburn and reduced quality of life. Patients with GERD with hypersensitivity to gastroesophageal reflux have similar levels of anxiety and similar quality-of-life scores as other patients with GERD. Copyright © 2015 AGA Institute.

Patients with gastroesophageal reflux disease (GERD) present with comorbid complications with implications for healthcare utilization. To date, little is known about the effects of GERD treatment with a proton-pump inhibitor (PPI) on patients’ subsequent healthcare utilization for acute respiratory infections (ARIs). This population-based study compared ARI episodes captured through outpatient visits, one year before and one year after GERD patients received PPI treatment. We used retrospective data from the Longitudinal Health Insurance Database 2005 in Taiwan, comparing 21,486 patients diagnosed with GERD from 2010 to 2012 with 21,486 age-sex matched comparison patients without GERD. Annual ARI episodes represented by ambulatory care visits for ARI (visits during a 7-day period bundled into one episode), were compared between the patient groups during the 1-year period before and after the index date (date of GERD diagnosis for study patients, first ambulatory visit in the same year for their matched comparison counterpart). Multiple regression analysis using a difference-in-difference approach was performed to estimate the adjusted association between GERD treatment and the subsequent annual ARI rate. We found that the mean annual ARI episode rate among GERD patients reduced by 11.4%, from 4.39 before PPI treatment, to 3.89 following treatment (mean change = -0.5 visit, 95% confidence interval (CI) = (-0.64, -0.36)). In Poisson regression analysis, GERD treatment showed an independent association with the annual ARI rate, showing a negative estimate (with p<0.001). The study suggests that GERD treatment with PPIs may help reduce healthcare visits for ARIs, highlighting the importance of treatment-seeking by GERD patients and compliance with treatment.

Challenge in pathologic diagnosis of Alport syndrome: evidence from correction of previous misdiagnosis

PubMed Central

2012-01-01

Background Pathologic studies play an important role in evaluating patients with Alport syndrome besides genotyping. Difficulties still exist in diagnosing Alport syndrome (AS), and misdiagnosis is a not-so-rare event, even in adult patient evaluated with renal biopsy. Methods We used nested case–control study to investigate 52 patients previously misdiagnosed and 52 patients initially diagnosed in the China Alport Syndrome Treatments and Outcomes Registry e-system. Results We found mesangial proliferative glomerulonephritis (MsPGN, 26.9%) and focal and segmental glomerulosclerosis (FSGS, 19.2%) were the most common misdiagnosis. FSGS was the most frequent misdiagnosis in female X-linked AS (fXLAS) patients (34.8%), and MsPGN in male X-linked AS (mXLAS) patients (41.2%). Previous misdiagnosed mXLAS patients (13/17, 76.5%) and autosomal recessive AS (ARAS) patients (8/12, 66.7%) were corrected after a second renal biopsy. While misdiagnosed fXLAS patients (18/23, 78.3%) were corrected after a family member diagnosed (34.8%) or after rechecking electronic microscopy and/or collagen-IV alpha-chains immunofluresence study (COL-IF) (43.5%) during follow-up. With COL-IF as an additional criterion for AS diagnosis, we found that patients with less than 3 criteria reached have increased risk of misdiagnosis (3.29-fold for all misdiagnosed AS patients and 3.90-fold for fXLAS patients). Conclusion We emphasize timely and careful study of electronic microscopy and COL-IF in pathologic evaluation of AS patients. With renal and/or skin COL-IF as additional criterion, 3 diagnosis criteria reached are the cutoff for diagnosing AS pathologically. PMID:23259488

High-resolution manometry (HRM) has resulted in new revelations regarding the pathophysiology of gastro-esophageal reflux disease (GERD). The impact of new HRM motor paradigms on reflux burden needs further definition, leading to a modern approach to motor testing in GERD. Focused literature searches were conducted, evaluating pathophysiology of GERD with emphasis on HRM. The results were discussed with an international group of experts to develop a consensus on the role of HRM in GERD. A proposed classification system for esophageal motor abnormalities associated with GERD was generated. Physiologic gastro-esophageal reflux is inherent in all humans, resulting from transient lower esophageal sphincter (LES) relaxations that allow venting of gastric air in the form of a belch. In pathological gastro-esophageal reflux, transient LES relaxations are accompanied by reflux of gastric contents. Structural disruption of the esophagogastric junction (EGJ) barrier, and incomplete clearance of the refluxate can contribute to abnormally high esophageal reflux burden that defines GERD. Esophageal HRM localizes the LES for pH and pH-impedance probe placement, and assesses esophageal body peristaltic performance prior to invasive antireflux therapies and antireflux surgery. Furthermore, HRM can assess EGJ and esophageal body mechanisms contributing to reflux, and exclude conditions that mimic GERD. Structural and motor EGJ and esophageal processes contribute to the pathophysiology of GERD. A classification scheme is proposed incorporating EGJ and esophageal motor findings, and contraction reserve on provocative tests during HRM. © 2017 John Wiley & Sons Ltd.

Histologic definition of gastro-esophageal reflux disease.

PubMed

Chandrasoma, Parakrama T

2013-07-01

To review recent data supporting the development of new histology-based definitions of gastro-esophageal reflux disease (GERD). Three precisely definable columnar epithelial types--cardiac, oxyntocardiac and intestinal--may be interposed between esophageal squamous epithelium and gastric oxyntic (acid secreting) mucosa. This enables definition of a new histologic concept: the squamo-oxyntic gap. The squamo-oxyntic gap is zero or very small in autopsies performed on patients without evidence of GERD. The gap progressively increases in length with the severity of GERD, indicating that the squamo-oxyntic gap is a marker for chronic GERD. The distal part of the gap lines gastric-type rugal folds and, therefore, is distal to the present endoscopic definition of the gastro-esophageal junction. I contend that this distal gap segment (which has esophageal submucosal glands) is actually the dilated distal esophagus; this is the pathologic correlate of destruction of the abdominal segment of the lower esophageal sphincter. The dilated distal esophagus is mistaken for 'gastric cardia' by present endoscopic definitions. I believe that these data support the adoption of novel histologic definitions of GERD as follows: the presence of any squamo-oxyntic gap defines GERD; the length of the gap is a measure of severity of chronic GERD; and the presence of intestinal metaplasia in the gap defines Barrett esophagus and cancer risk.

In the last two decades, non-invasive methods through acoustic analysis of voice signal have been proved to be excellent and reliable tool to diagnose vocal fold pathologies. This paper proposes a new feature vector based on the wavelet packet transform and singular value decomposition for the detection of vocal fold pathology. k-means clustering based feature weighting is proposed to increase the distinguishing performance of the proposed features. In this work, two databases Massachusetts Eye and Ear Infirmary (MEEI) voice disorders database and MAPACI speech pathology database are used. Four different supervised classifiers such as k-nearest neighbour (k-NN), least-square support vector machine, probabilistic neural network and general regression neural network are employed for testing the proposed features. The experimental results uncover that the proposed features give very promising classification accuracy of 100% for both MEEI database and MAPACI speech pathology database.

Chronic Cough and OSA: A New Association?

PubMed Central

Sundar, Krishna M.; Daly, Sarah E.

2011-01-01

Chronic cough is defined as cough lasting more than 2 months. Common causes for chronic cough in nonsmokers with normal chest radiographs and pulmonary functions include gastroesophageal reflux disease (GERD), cough-variant asthma (CVA), and upper airway cough syndrome (UACS). Current guidelines recommend diagnosing the etiology of chronic cough based upon the results of therapy for suspected GERD, CVA, and UACS. Despite following current recommendations for diagnosis and treatment, the cause for a significant proportion of chronic cough remains unexplained. Recent reports indicate the resolution of chronic cough following treatment of concomitantly diagnosed obstructive sleep apnea (OSA). Whether this represents a co-occurrence of two commonly prevalent disorders or a pathophysiologic relationship between OSA and cough remains unknown. This review offers insights into a pathophysiologic link between OSA and the commonly purported etiologies for cough, namely, GERD, UACS, and CVA. In addition, evidence for a relationship between airway inflammation that can trigger or perpetuate cough and OSA is discussed. This review explores mechanisms by which nocturnal continuous positive airway therapy resolves cough by improving underlying airway inflammation secondary to OSA and impacts upon GERD, CVA, and UACS.

Gastroesophageal reflux disease (GERD) has a large economic burden with important complications that include esophagitis, Barrett's esophagus, and adenocarcinoma. Despite endoscopy, validated patient questionnaires, and traditional ambulatory pH monitoring, the diagnosis of GERD continues to be challenging. Areas covered: This review will explore the difficulties in diagnosing GERD with a focus on new developments, ranging from basic fundamental changes (histology and immunohistochemistry) to direct patient care (narrow-band imaging, impedance, and response to anti-reflux surgery). We searched PubMed using the noted keywords. We included data from full-text articles published in English. Further relevant articles were identified from the reference lists of review articles. Expert commentary: Important advances in novel parameters in intraluminal impedance monitoring such as baseline impedance monitoring has created some insight into alternative diagnostic strategies in GERD. Recent advances in endoscopic assessment of esophageal epithelial integrity via mucosal impedance measurement is questioning the paradigm of prolonged ambulatory testing for GERD. The future of reflux diagnosis may very well be without the need for currently employed technologies and could be as simple as assessing changes in epithelia integrity as a surrogate marker for GERD. However, future studies must validate such an approach.

Meniscal tears are often associated with anterior cruciate ligament (ACL) injury and may lead to pain and discomfort in humans. Maximal preservation of meniscal tissue is highly desirable to mitigate the progression of osteoarthritis. Guidelines of which meniscal tears are amenable to repair and what part of damaged tissues should be removed are elusive and lacking consensus. Images of microstructural changes in meniscus would potentially guide the surgeons to manage the meniscal tears better, but the resolution of current diagnostic techniques is limited for this application. In this study, we demonstrated the feasibility of using optical coherence tomography (OCT) for the diagnosis of meniscal pathology. Torn medial menisci were collected from dogs with ACL insufficiency. The torn meniscus was divided into three tissue samples and scanned by OCT and scanning electron microscopy (SEM). OCT and SEM images of torn menisci were compared. Each sample was evaluated for gross and microstructural abnormalities and reduction or loss of birefringence from the OCT images. The abnormalities detected with OCT were described for each type of tear. OCT holds promise in non-destructive and fast assessment of microstructural changes and tissue birefringence of meniscal tears. Future development of intraoperative OCT may help surgeons in the decision making of meniscal treatment.

Nodular hidradenocarcinoma (NHAC), an eccrine carcinoma, has been reported in the dermatology and pathology literature, but few references have been made in the otolaryngology literature even though the head and neck is a common site of occurrence. A case report of a 37-year-old Hispanic man with a right-sided neck mass diagnosed preoperatively as a parotid mass by imaging and fine-needle aspiration is presented. After presentation at our multidisciplinary tumor board, excision of the mass was undertaken. Final pathology revealed a NHAC, which is presented in our report. NHAC is an aggressive malignant tumor that is often misdiagnosed preoperatively and that must be treated with aggressive multimodality therapy for increased survival.

Background. Incomplete control of troublesome regurgitation and extraesophageal manifestations of chronic gastroesophageal reflux disease (GERD) is a known limitation of proton pump inhibitor (PPI) therapy. This multicenter randomized study compared the efficacy of transoral incisionless fundoplication (TIF) against PPIs in controlling these symptoms in patients with small hiatal hernias. Methods. Between June and August 2012, 63 patients were randomized at 7 US community hospitals. Patients in the PPI group were placed on maximum standard dose (MSD). Patients in the TIF group underwent esophagogastric fundoplication using the EsophyX2 device. Primary outcome was elimination of daily troublesome regurgitation or extraesophageal symptoms. Secondary outcomes were normalization of esophageal acid exposure (EAE), PPI usage and healing of esophagitis. Results. Of 63 randomized patients (40 TIF and 23 PPI), 3 were lost to follow-up leaving 39 TIF and 21 PPI patients for analysis. At 6-month follow-up, troublesome regurgitation was eliminated in 97% of TIF patients versus 50% of PPI patients, relative risk (RR) = 1.9, 95% confidence interval (CI) = 1.2-3.11 (P = .006). Globally, 62% of TIF patients experienced elimination of regurgitation and extraesophageal symptoms versus 5% of PPI patients, RR = 12.9, 95% CI = 1.9-88.9 (P = .009). EAE was normalized in 54% of TIF patients (off PPIs) versus 52% of PPI patients (on MSD), RR = 1.0, 95% CI = 0.6-1.7 (P = .914). Ninety percent of TIF patients were off PPIs. Conclusion. At 6-month follow-up, TIF was more effective than MSD PPI therapy in eliminating troublesome regurgitation and extraesophageal symptoms of GERD. PMID:24756976

The cause of idiopathic pulmonary fibrosis (IPF) remains unknown, yet gastro-esophageal reflux disease (GERD) is highly prevalent in this population. GERD prevalence was studied, and esophageal function tests (EFT) were assessed in Chinese IPF patients. We prospectively studied 69 IPF patients who undertook both stationary High Resolution esophageal Manometry/Impedance (HRiM) and 24-hour esophageal Multi-Channel Intraluminal Impedance with pH Recordings (MII/pH). Patients were divided into GERD+ and GERD- groups according to pH results. Controls were HRiM treated healthy volunteers, and patients without IPF received HRiM and MII/pH diagnosed with GERD. 69 IPF patients, 62 healthy volunteers, and 88 IPF negative GERD patients were selected. GERD prevalence in IPF was 43/69 (62.3%), and 58.1% of patients presented with at least one typical symptom. Symptoms had a sensitivity of 58.1%, a specificity of 61.6%, a positive predictive value of 71.4% and a negative predictive of 47.1%. Compared with healthy volunteers, IPF patients had significantly decreased lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure (UESP) and complete bolus transit rate (CBTR). By contrast, IPF patients had increased total bolus transit time and prevalence of weak peristalsis. MII/pH showed that one third of IPF patients had abnormal distal and proximal reflux, especially non-acid reflux. Compared with GERD patients without IPF, GERD patients with IPF had significantly decreased CBTR and UESP with increased bolus exposure time. GERD prevalence in IPF was high, but symptoms alone were an unreliable predictor of reflux. IPF patients had lower LESP and UESP, impaired esophageal peristalsis and bolus clearance function with more proximal reflux events.

Mulberry hypertrophy occasionally coexists with sinonasal pathologies. There are very few reports in the literature on this clinical entity. We conducted a retrospective study to draw attention to this condition in the context of accompanying sinonasal pathologies. Our study group was made up of 68 patients-51 males and 17 females, aged 13 to 57 years (mean: 34.9)-who had been diagnosed with mulberry hypertrophy and at least one accompanying sinonasal pathology. All patients had a long-standing chronic discharge. Forty-nine of these patients (72.1%) had unilateral mulberry hypertrophy. The most common concomitant pathologies were chronic rhinosinusitis and ostiomeatal complex disease; others included septal deviation, nasal polyposis, allergic rhinitis, and concha bullosa. Thirty-six patients (52.9%) with varying degrees of choanal/nasal obstruction were operated on with endoscopic excision to treat the mulberry hypertrophy. In all, most patients underwent some sort of surgery to treat either the mulberry hypertrophy or the accompanying sinonasal pathology. Based on our findings, we suggest a clinical staging system to serve as a way to standardize management and guide future basic and clinical research.

- Intradepartmental consultation is a routine practice commonly used for new diagnoses. Expert interinstitutional case review provides insight into particularly challenging cases. - To investigate the practice of breast pathology consultation at a large tertiary care center. - We reviewed breast pathology cases sent for private consultation and internal cases reviewed by multiple pathologists at a tertiary center. Requisitions and reports were evaluated for diagnostic reason for consultation, rate of multiple pathologist review at the tertiary center, use of immunohistochemistry, and, for private consultation cases, type of sender and concordance with the outside diagnosis. - In the 985 private consultation cases, the most frequent reasons for review were borderline atypia (292 of 878; 33.3%), papillary lesion classification (151 of 878; 17.2%), evaluating invasion (123 of 878; 14%), subtyping carcinoma (75 of 878; 8.5%), and spindle cell (67 of 878; 7.6%) and fibroepithelial (65 of 878; 7.4%) lesion classification. Of 4981 consecutive internal cases, 358 (7.2%) were reviewed, most frequently for borderline atypia (90 of 358; 25.1%), subtyping carcinoma (63 of 358; 17.6%), staging/prognostic features (59 of 358; 16.5%), fibroepithelial lesion classification (45 of 358; 12.6%), evaluating invasion (37 of 358; 10.3%), and papillary (20 of 358; 5.6%) and spindle cell (18 of 358; 5.0%) lesion classification. Of all internal cases, those with a final diagnosis of atypia had a significantly higher rate of review (58 of 241; 24.1%) than those with benign (119 of 2933; 4.1%) or carcinoma (182 of 1807; 10.1%) diagnoses. Immunohistochemistry aided in diagnosis of 39.7% (391 of 985) and 21.2% (76 of 359) of consultation and internally reviewed cases, respectively. - This study confirms areas of breast pathology that represent diagnostic challenge and supports that pathologists are appropriately using expert consultation.

AIM To compare long-term occurrence of gastroesophageal reflux disease (GERD) between two different types of peroral endoscopic myotomy (POEM) for achalasia. METHODS We included all patients with achalasia who underwent POEM at our hospital from August 2011 to October 2012 and had complete GERD evaluation with ≥ 3 years of follow-up. They were divided into circular or full-thickness myotomy groups according to the depth of myotomy. Demographics, Eckardt score, manometry results, 24-h pH monitoring, and GERD symptoms were recorded and compared between the two groups. RESULTS We studied 56 patients (32 circular myotomy and 24 full-thickness myotomy) with complete GERD evaluation. There was no significant difference between the two groups in terms of treatment success (defined as Eckardt score ≤ 3), postoperative Eckardt score, mean basal lower esophageal sphincter pressure, and 4-s integrated relaxation pressure (4sIRP). Postoperative abnormal esophageal acid exposure was found in 25 patients (44.6%). A total of 13 patients (23.2%) had GERD symptoms and 12 had esophagitis (21.4%). Clinically relevant GERD (abnormal esophageal acid exposure associated with GERD symptoms and/or esophagitis) was diagnosed in 13 patients (23.2%). Multivariate analysis revealed that full-thickness myotomy and low level of postoperative 4sIRP were predictive factors for clinically relevant GERD. CONCLUSION Efficacy and manometry are comparable between achalasia patients treated with circular or full-thickness myotomy. But patients with full-thickness myotomy and low postoperative 4sIRP have more GERD. PMID:27895430

2014-01-01

Nocturnal bruxism is associated with gastroesophageal reflux disease (GERD), and GERD is strongly associated with obstructive sleep apnea (OSA). Gender and ethnic differences in the prevalence and clinical presentation of these often overlapping sleep disorders have not been well documented. Our aim was to examine the associations between, and the symptoms associated with, nocturnal GERD and sleep bruxism in patients with OSA, and to examine the influence of gender and ethnicity. A retrospective chart review was performed of patients diagnosed with OSA at an academic sleep center. The patients completed a sleep questionnaire prior to undergoing polysomnography. Patients with confirmed OSA were evaluated based on gender and ethnicity. Associations were determined between sleep bruxism and nocturnal GERD, and daytime sleepiness, insomnia, restless legs symptoms, and markers of OSA severity in each group. In these patients with OSA, the prevalence of nocturnal GERD (35%) and sleep bruxism (26%) were higher than the general population. Sleep bruxism was more common in Caucasians than in African Americans or Hispanics; there was no gender difference. Nocturnal GERD was similar among all gender and ethnic groups. Bruxism was associated with nocturnal GERD in females, restless legs symptoms in all subjects and in males, sleepiness in African Americans, and insomnia in Hispanics. Nocturnal GERD was associated with sleepiness in males and African Americans, insomnia in females, and restless legs symptoms in females and in Caucasians. Patients with OSA commonly have comorbid sleep bruxism and nocturnal GERD, which may require separate treatment. Providers should be aware of differences in clinical presentation among different ethnic and gender groups.

Early HPV infection in males is difficult to detect clinically and pathologically. This study assessed histopathology in diagnosing male genital HPV. External genital lesions (n = 352) were biopsied, diagnosed by a dermatopathologist, and HPV genotyped. A subset (n = 167) was diagnosed independently by a second dermatopathologist and also re-evaluated in detail, tabulating the presence of a set of histopathologic characteristics related to HPV infection. Cases that received discrepant diagnoses or HPV-related diagnoses were evaluated by a third dermatopathologist (n = 163). Across dermatopathologists, three-way concordance was fair (k = 0.30). Pairwise concordance for condyloma was fair to good (k = 0.30-0.67) and poor to moderate for penile intraepithelial neoplasia (k = -0.05 to 0.42). Diagnoses were 44-47% sensitive and 65-72% specific for HPV 6/11-containing lesions, and 20-37% sensitive and 98-99% specific for HPV 16/18. Presence of HPV 6/11 was 75-79% sensitive and 35% specific for predicting pathologic diagnosis of condyloma. For diagnosis of penile intraepithelial neoplasia, HPV 16/18 was 95-96% specific but only 40-64% sensitive. Rounded papillomatosis, hypergranulosis, and dilated vessels were significantly (P < 0.05) associated with HPV 6/11. Dysplasia was significantly (P = 0.001) associated with HPV 16/18. Dermatopathologists' diagnoses of early male genital HPV-related lesions appear discordant with low sensitivity, while genotyping may overestimate clinically significant HPV-related disease. Rounded papillomatosis, hypergranulosis, and dilated vessels may help establish diagnosis of early condyloma. © 2015 Wiley Periodicals, Inc.

Original research in pathology: judgment, or evidence-based medicine?

PubMed

Crawford, James M

2007-02-01

Pathology is both a medical specialty and an investigative scientific discipline, concerned with understanding the essential nature of human disease. Ultimately, pathology is accountable as well, as measured by the accuracy of our diagnoses and the resultant patient care outcomes. As such, we must consider the evidence base underlying our practices. Within the realm of Laboratory Medicine, extensive attention has been given to testing accuracy and precision. Critical examination of the evidence base supporting the clinical use of specific laboratory tests or technologies is a separate endeavor, to which specific attention must be given. In the case of anatomic pathology and more specifically surgical pathology, the expertise required to render a diagnosis is derived foremost from experience, both personal and literature-based. In the first instance, knowledge of the linkage between one's own diagnoses and individual patient outcomes is required, to validate the role of one's own interpretations in the clinical course of patients. Experience comes from seeing this linkage first hand, from which hopefully comes wisdom and, ultimately, good clinical judgment. In the second instance, reading the literature and learning from experts is required. Only a minority of the relevant literature is published in pathology journals to which one may subscribe. A substantial portion of major papers relevant to the practice of anatomic pathology are published in collateral clinical specialty journals devoted to specific disease areas or organs. Active effort is therefore required to seek out the literature beyond the domain of pathology journals. In examining the published literature, the essential question then becomes: Does the practice of anatomic pathology fulfill the tenets of 'evidence-based medicine' (EBM)? If the pinnacle of EBM is 'systematic review of randomized clinical trials, with or without meta-analysis', then anatomic pathology falls far short. Our published

Participants were assessed for psychopathology and gambling disorders using the Mini International Neuropsychiatric Interview, the National Opinion Research Center DSM Screen for Gambling Problems, and the Adult ADHD Self-Report Scale. Facets of personality were assessed using the NEO Personality Inventory–Revised. Group differences emerged across several facets of personality when analyzed using multivariate statistics. Although both groups experienced difficulties in several areas compared with norming data (e.g., greater depression, higher impulsivity, lower self-esteem and lower self-discipline), these facets of personality were more pronounced in pathological gamblers with ADHD. Most notable among these differences are tendencies for gamblers with ADHD to experience greater levels of emotional instability, interpersonal sensitivity and stress proneness. Pathological gamblers with ADHD also appear to experience lower self-esteem, greater difficulty being assertive and lower levels of self-discipline. Surprisingly, both groups were comparable on facets of impulsivity. These findings suggest that pathological gamblers diagnosed with adult ADHD may experience additional challenges compared with pathological gamblers without ADHD. PMID:22815658

Smartphone applications (apps) have become increasingly prevalent in medicine. Due to most pathologists, pathology trainees, technicians, and medical students use smartphones; apps can be a different way for general pathology education. "General pathologist-helper (GP-HELPER)" is a novel app developed as a reference tool in general pathology and especially for general pathologists, developed for Android and iOS platforms. "GP-HELPER," was created using Mobincube website platform. This tool also integrates "FORUM GP-HELPER," an external website created using Miarroba website (http://forum-gp-helper.mboards.com) and "COMMUNITY GP-HELPER" a multichannel chat created using Chatango website platform. The application was released in July 2015, and it is been periodically updated since then. The app has permanent information (offline data) about different pathology protocols (TNM latest edition, protocols regarding management of tumors of unknown primary origin, and flowcharts for some of the most difficult tumors to diagnose) and a database with more than 5000 immunohistochemistry results from different tumors. Online data have links to more than 1100 reference pathology video lectures, 250 antibodies information, more than 70 pathology association websites, 46 pathology providers, and 78 outstanding pathology journal websites. Besides this information, the app has two interactive places such as "FORUM GP-HELPER" and "COMMUNITY GP-HELPER" that let users to stay in touch everywhere and every time. Expert consult section is also available. "GP-HELPER" pretends to integrate offline and online data about pathology with two interactive external places in order to represent a reference tool for general pathologists and associate members.

Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal pathology in infants and young children. Ultrasonography (US) has been considered to be a reliable diagnostic tool for GERD but the severity of GERD and the clinical implications based on imaging findings has not been evaluated. To compare the diagnostic value of lower esophageal US with that of barium swallow in demonstrating the severity of GERD. Fifty one pediatric patients, age between 1 month to 12 years, 34 male and 17 female with clinical suspicion of GERD were included. The patients were initially submitted to barium swallow (BS) and subsequently to transabdominal US. During BS, the number of gastroesophageal reflux episodes was documented in a 5-minute period. Transabdominal US documented the number and duration of reflux episodes during a 5-minute period, the angle of His, mucosal thickness, and intraabdominal esophageal length (IAEL). Duration and number of reflux episodes in US were significantly higher in patients that had severe gastroesophageal refluxes at BS. At US the cutoff point of 9.5 seconds (sensitivity 80%, specificity 60%) for reflux duration and more than 2 episodes in 5 minute ultrasound study (sensitivity 75%, specificity 58%) were defined to correlate with severe gastroesophageal reflux at BS.The angle of His, the esophageal wall mucosal thickness, and the IAEL did not correlate with the severity of GERD detected in BS. US can predict the severity of GERD. Therefore, except in the case of specific patients in whom mechanical causes are suspected to be responsible for GERD, BS can be replaced by US.

To report the number and frequency of incidental findings (IFs) detected during magnetic resonance (MR) imaging screening of the temporomandibular joint (TMJ) and to define related diseases. Bilateral TMJ MR images in the sagittal and coronal sections, from 518 patients with TMJ symptoms were evaluated retrospectively. Patients who were diagnosed with IFs were sent for consultation and clarification of the findings. Patient age, gender, IFs, locations, and diseases were classified and noted.  Results: Seventy-eight (15%) patients were diagnosed with 117 IFs. Of them, 43 were diagnosed with a single IF, and 35 were diagnosed with more than one IF. The most frequent locations were paranasal sinuses and mastoid air cells. The most frequent diseases were inflammatory and cystic lesions.  Discussion: While examining TMJ MR images, it is important to check for evidence of IFs or pathologies that may have mimicked signs and symptoms of TMJ disorders.

To study the specific features of the clinical course of gastroesophageal reflux disease (GERD) associated with duodenogastroesophageal reflux (DGER) in patients with chronic acalculous cholecystitis (CAC) and cholelithiasis (CL), as well as qualitative and quantitative characteristics. The clinical, morphological, motor tonic characteristics of the esophagogastroduodenal area, mucosal microbial biocenosis in the esophagus, stomach, and duodenum were studied in detail in 83 patients with GERD that was associated with DGER and ran concurrently with CAC or CL. Impaired duodenal propulsive activity as a concomitance of the signs of gastrostasis and duodenal dyskinesia with dyscoordination of both anthroduodenal and duodenojejunal propulsion and with the development of duodenogastric reflux and DGER, which in turn determine esophageal and gastric pH values is shown to be of importance in CAC and CL, which match GERD. Abnormal microbiocenosis in the upper digestive tract is characterized by the higher quantitative and qualitative content of the mucous microflora. Opportunistic microorganisms exhibit cytotoxic, hemolytic, lecithinase, caseinolytic, urease, and RNAase activities. The found specific features of the course of GERD associated with DGER in patients with biliary tract abnormalities lead us to search for novel therapeutic approaches based on the correction of digestive motor tonic disorders and abnormal microbiocenoses of the mucous flora in the esophagus, stomach, and duodenum.

The origin and significance of cardiac mucosa at the gastro-oesophageal junction are controversial. In the prospective Central European multicentre histoGERD trial, we aimed to assess the prevalence of cardiac mucosa, characterized by the presence of glands composed of mucous cells without parietal cells, and to relate its presence to features related to gastro-oesophageal reflux disease (GORD). One thousand and seventy-one individuals (576 females and 495 males; median age 53 years) were available for analysis. Overall, in biopsy specimens systematically taken from above and below the gastro-oesophageal junction, cardiac mucosa was observed in 713 (66.6%) individuals. Its presence was associated with patients' symptoms and/or complaints (P = 0.0025), histological changes of the squamous epithelium (P < 0.001) indicative of GORD, intestinal metaplasia (P < 0.001), and an endoscopic diagnosis of oesophagitis (P < 0.001). No association with an endoscopic diagnosis of Barrett's oesophagus or with gastric pathology, particularly Helicobacter infection, was observed. Cardiac mucosa is a common finding in biopsy specimens taken from the gastro-oesophageal junction. Its association with reflux symptoms, histological changes indicating GORD and the endoscopic diagnosis of oesophagitis suggests that injury and repair related to GORD contribute to its development and/or expansion. © 2014 John Wiley & Sons Ltd.

Forensic Pathology Education in Pathology Residency

Forensic pathology is a fundamental part of anatomic pathology training during pathology residency. However, the lack of information on forensic teaching suggests the highly variable nature of forensic education. A survey of pathology residency program directors was performed to determine key aspects of their respective forensic rotations and curriculum. A total of 38.3% of programs from across the country responded, and the survey results show 5.6% don’t require a forensic pathology rotation. In those that do, most forensic pathology rotations are 4 weeks long, are done at a medical examiner’s office, and require set prerequisites. A total of 21.1% of responding programs have residents who are not receiving documented evaluations for this rotation. While 39.6% of programs have a defined forensics curriculum, as many as 15% do not. Furthermore, nearly 43% of programs place no limit on counting forensic autopsies when applying for pathology board examinations. Our survey confirmed the inconsistent nature of forensic pathology training in resident education. Additionally, our curriculum was reorganized to create a more robust educational experience. A pre- and post-forensic lecture quiz and Resident In-Service Examination scores were analyzed to determine our curriculum’s impact and effectiveness. Analysis of our pre- and post-lecture quiz showed an improved overall average as well as an increase in Resident In-Service Examination scores, indicating improved general forensic pathology knowledge. Using this knowledge, along with changes in our curriculum, we generated a number of recommendations for improving forensic pathology education in pathology residency. PMID:28913415

Evaluation of the respiratory response to proton pump inhibitors (PPI) in children with obstructive sleep apnea syndrome (OSAS) and gastroesophageal reflux disease (GERD). Of 131 children diagnosed with OSAS (Apnea Hypopnea Index, AHI >1/h), 37 children (6.9 years; 28.24%) with GERD symptoms (>3 times/week) were included. Overnight polysomnography with 24h pH-metry was performed before and after 4-8 weeks of PPI treatment (omeprazole once a day, 1mg/kg). Of 37 children, 21 were diagnosed with acid GERD where pre- and post-treatment reflux indexes were 14.09±1.47 vs. 7.73±1.36; (p<0.001). The number of obstructive apneas and hypopneas decreased after PPI treatment, resulting in an AHI reduction from 13.08±3.11/h to 8.22±2.52/h; (p<0.01). Respiratory response to PPI ranged from complete resolution of OSA (three children with mild OSA; AHI<5/h; 10.31years; 14.29%) to lack of significant AHI change (six children with severe OSA; AHI>10/h; 3.62 years; 28.57%). Post-treatment AHI was predicted by pre-treatment reflux index (adjusted R(2)=0.487; p<0.001). Reduction of obstructive respiratory events following short-term PPI treatment in children with both GERD and OSAS may suggest a causal relationship between apnea and reflux in some children. Questionnaire screening for GERD in children with OSAS may be of benefit. Copyright © 2012 Elsevier B.V. All rights reserved.

Successful treatment of suspected organizing pneumonia in a patient without typical imaging and pathological characteristic: A case report.

Organizing pneumonia (OP) is a clinicopathological entity characterized by granulation tissue plugs in the lumen of small airways, alveolar ducts, and alveoli. Diagnosis of OP needs the combination of clinical features, imaging and pathology. But it occurs often that there are no typical pathological features to support the diagnosis, which poses a challenge for clinicians' diagnosis and treatment. We diagnosed a case of OP without typical imaging and pathological characteristic and treated successfully. Finally we confirmed the pathological diagnosis. Not every OP case is supported by pathological evidence and typical imaging changes. It is important for us to judge and decide the diagnosis according to clinical experience.

Evaluation of common elbow pathologies: a focus on physical examination.

Elbow tendinopathy accounts for the majority of elbow pathology in patients presenting to upper extremity and sports medicine surgeons. With increased participation in overhead sports in an aging population, the incidence of elbow injuries has risen. A comprehensive knowledge of elbow anatomy and biomechanical function of the elbow complex is prerequisite in the assessment of patients with elbow injuries; however, a thorough understanding of alternative and confounding pathologies is essential for accurate diagnosis. Because tendinopathy, tendonitis, and tendon tears have an anatomic basis for their pathology, a targeted history and meticulous physical examination often yields an accurate clinical diagnosis. The importance of physical examination and provocative examination maneuvers must be stressed in a technologically advanced era where clinical diagnosis is too commonly attained solely by advanced imaging modalities. A revived dedication to the physical examination may enhance our ability to correctly diagnose various pathologies about the elbow. Early and accurate clinical diagnosis is the first step in the proper initiation of treatment modalities and improvement in overall patient outcome.

To determine the impact of cortical Alzheimer disease pathology on shunt responsiveness in individuals treated for idiopathic normal pressure hydrocephalus (iNPH), 37 patients clinically diagnosed with iNPH participated in a prospective study in which performance on neurologic, psychometric, and gait measures before and 4 months after shunting was correlated with amyloid β plaques, neuritic plaques, and neurofibrillary tangles observed in cortical biopsies obtained during shunt insertion. No complications resulted from biopsy acquisition. Moderate to severe pathology was associated with worse baseline cognitive performance and diminished postoperative improvement on NPH symptom severity scales, gait measures, and cognitive instruments compared to patients lacking pathology.

ERP-based detection of brain pathology in rat models for preclinical Alzheimer's disease

NASA Astrophysics Data System (ADS)

Nouriziabari, Seyed Berdia

Early pathological features of Alzheimer's disease (AD) include the accumulation of hyperphosphorylated tau protein (HP-tau) in the entorhinal cortex and progressive loss of basal forebrain (BF) cholinergic neurons. These pathologies are known to remain asymptomatic for many years before AD is clinically diagnosed; however, they may induce aberrant brain processing which can be captured as an abnormality in event-related potentials (ERPs). Here, we examined cortical ERPs while a differential associative learning paradigm was applied to adult male rats with entorhinal HP-tau, pharmacological blockade of muscarinic acetylcholine receptors, or both conditions. Despite no impairment in differential associative and reversal learning, each pathological feature induced distinct abnormality in cortical ERPs to an extent that was sufficient for machine classifiers to accurately detect a specific type of pathology based on these ERP features. These results highlight a potential use of ERPs during differential associative learning as a biomarker for asymptomatic AD pathology.

In this study, we evaluated pathological changes in the tooth and pharynx of GERD rats to elucidate the association between gastric acid reflux and oral and pharyngeal diseases. An experimental rat model of chronic acid reflux esophagitis was surgically created. The oral cavities were observed histologically every 2 weeks until 20 weeks after surgery. At 10 weeks after surgery, molar crown heights in GERD rats were shorter than that in control rats, and inflammatory cell infiltration by gastric acid reflux was found in the periodontal mucosa of GERD rats. Furthermore, dental erosion progressed in GERD rats at 20 weeks after surgery, and enamel erosion and dentin exposure were observed. During the same period, inflammatory cell infiltration was observed in the mucosa of the posterior part of the tongue. These findings suggest that gastric acid reflux may be one of the exacerbating factors of dental erosion, periodontitis and glossitis. We investigated oral changes in an experimental rat model of GERD and observed development of dental erosion, periodontitis and glossitis. Our findings suggested chronic gastric acid reflux may be involved in the pathogenesis of oral disease. Copyright © 2017 Elsevier B.V. All rights reserved.

The opportunity to integrate clinical decision support systems into clinical practice is limited due to the lack of structured, machine readable data in the current format of the electronic health record. Natural language processing has been designed to convert free text into machine readable data. The aim of the current study was to ascertain the feasibility of using natural language processing to extract clinical information from >76,000 breast pathology reports. APPROACH AND PROCEDURE: Breast pathology reports from three institutions were analyzed using natural language processing software (Clearforest, Waltham, MA) to extract information on a variety of pathologic diagnoses of interest. Data tables were created from the extracted information according to date of surgery, side of surgery, and medical record number. The variety of ways in which each diagnosis could be represented was recorded, as a means of demonstrating the complexity of machine interpretation of free text. There was widespread variation in how pathologists reported common pathologic diagnoses. We report, for example, 124 ways of saying invasive ductal carcinoma and 95 ways of saying invasive lobular carcinoma. There were >4000 ways of saying invasive ductal carcinoma was not present. Natural language processor sensitivity and specificity were 99.1% and 96.5% when compared to expert human coders. We have demonstrated how a large body of free text medical information such as seen in breast pathology reports, can be converted to a machine readable format using natural language processing, and described the inherent complexities of the task.

Objective To describe the Alzheimer disease (AD)-like clinical and pathological features, including marked neurofibrillary tangle (NFT) pathology, of a familial prion disease due to a rare nonsense mutation of the prion gene (PRNP). Methods Longitudinal clinical assessments were available for the proband and her mother. After death, both underwent neuropathological evaluation. PRNP was sequenced after failure to find immunopositive Aβ deposits in the proband and the documentation of prion protein (PrP) immunopositive pathology. Results The proband presented at age 42 years with a 3-year history of progressive short-term memory impairment and depression. Neuropsychological testing found impaired memory performance, with relatively preserved attention and construction. She was diagnosed with AD and died at age 47 years. Neuropathologic evaluation revealed extensive limbic and neocortical NFT formation and neuritic plaques consistent with a Braak stage of VI. The NFTs were immunopositive, with multiple tau antibodies, and electron microscopy revealed paired helical filaments. However, the neuritic plaques were immunonegative for Aβ, whereas immunostaining for PrP was positive. The mother of the proband had a similar presentation, including depression, and had been diagnosed clinically and pathologically as AD. Reevaluation of her brain tissue confirmed similar tau and PrP immunostaining findings. Genetic analysis revealed that both the proband and her mother had a rare PRNP mutation (Q160X) that resulted in the production of truncated PrP. Interpretation We suggest that PRNP mutations that result in a truncation of PrP lead to a prolonged clinical course consistent with a clinical diagnosis of AD and severe AD-like NFTs. PMID:21416485

Study Objectives : Nocturnal bruxism is associated with gastroesophageal reflux disease (GERD), and GERD is strongly associated with obstructive sleep apnea (OSA). Gender and ethnic differences in the prevalence and clinical presentation of these often overlapping sleep disorders have not been well documented. Our aim was to examine the associations between, and the symptoms associated with, nocturnal GERD and sleep bruxism in patients with OSA, and to examine the influence of gender and ethnicity. Methods : A retrospective chart review was performed of patients diagnosed with OSA at an academic sleep center. The patients completed a sleep questionnaire prior to undergoing polysomnography. Patients with confirmed OSA were evaluated based on gender and ethnicity. Associations were determined between sleep bruxism and nocturnal GERD, and daytime sleepiness, insomnia, restless legs symptoms, and markers of OSA severity in each group. Results : In these patients with OSA, the prevalence of nocturnal GERD (35%) and sleep bruxism (26%) were higher than the general population. Sleep bruxism was more common in Caucasians than in African Americans or Hispanics; there was no gender difference. Nocturnal GERD was similar among all gender and ethnic groups. Bruxism was associated with nocturnal GERD in females, restless legs symptoms in all subjects and in males, sleepiness in African Americans, and insomnia in Hispanics. Nocturnal GERD was associated with sleepiness in males and African Americans, insomnia in females, and restless legs symptoms in females and in Caucasians. Conclusion : Patients with OSA commonly have comorbid sleep bruxism and nocturnal GERD, which may require separate treatment. Providers should be aware of differences in clinical presentation among different ethnic and gender groups. PMID:25352924

Introduction and objective: Colonic wall thickening is a common condition in a number of benignant and malignant diseases. This study investigated the accuracy of radiological diagnoses in patients diagnosed with colonic wall thickening using multislice CT (MDCT). Materials and Method: Files of patients with colonic wall thickening diagnosed with 64-slice MDCT were reviewed retrospectively. The colonoscopy results of these patients were grouped under neoplastic process (cancer and adenomatous polyp), inflammatory bowel disease (IBD), diverticulitis and other etiology (nonspecific events, ischemic colitis, solitary rectal ulcer, external compression, secondary to volvulus and radiotherapy), and the results were statistically evaluated. p values < 0.05 were considered statistically significant. Results: The study was performed on 505 files (290 males [57.4%], 215 females [42.6%], mean age: 49.15 ± 18.4 years). CT and colonoscopic diagnoses were reviewed and the following CT to colonoscopy ratios was observed: neoplastic process: 44.4% vs. 40.2%; IBD: 42.4% vs. 42.4%; diverticulitis: 4% vs. 4.2%; other etiology: 9.3% vs. 3.2%. Colonoscopy failed to identify pathology in 9.9% of the patients. The sensitivity, specificity, PPV, NPV and accuracy of CT were 95.6%, 90.4%, 87.1%, 96.8% and 92.4%, respectively, in detecting neoplastic processes; 97.2%, 97.9%, 97.2%, 97.9% and 97.6%, respectively, in detecting IBD; 90.5%, 99.8%, 95%, 99.6% and 99.4%, respectively, in detecting diverticulitis, and 50%, 96,7%, 62.5%, 94.6% and 92%, respectively, in detecting other etiology. Conclusion: While, accuracy of 64 slice-CT in diagnosing colonic wall thickenings secondary especially to neoplastic processes, IBD and diverticulitis was significantly higher, but differential diagnosis is challenging in pathologies due to other etiologies.

Abstract Baseline impedance (BI) measurement can be used to evaluate the status of the esophageal mucosa integrity. We hypothesized that impaired esophageal mucosal integrity may play a causative role in patients with nongastroesophageal reflux disease (non-GERD)–related noncardiac chest pain (NCCP). This retrospective study analyzed 24-hour multichannel intraluminal impedance-pH testing data from 77 patients with NCCP and 5 healthy volunteers. BI was calculated at 3 cm (distal esophagus) and 17 cm (proximal esophagus) above the lower esophageal sphincter. GERD was defined by the presence of pathologic acid exposure or reflux esophagitis. Among the 77 patients with NCCP, 16 (20.8%) were classified into the GERD-related NCCP group and 61 (79.2%) into the non-GERD-related NCCP group. BI (median, interquartile range) of the non-GERD-related NCCP group was lower than the control group at the proximal esophagus (2507 Ω, 2156–3217 vs 3855 Ω, 3238–4182, P = 0.001) but was similar at the distal esophagus. The GERD-related NCCP group showed lower BI than the control group at both the distal and proximal esophagus (2024 Ω, 1619–2308 vs 3203 Ω, 2366–3774, P = 0.007 and 2272 Ω, 1896–2908 vs 3855 Ω, 3238–4182, P = 0.003, respectively). At the distal esophagus, BI was lower in the GERD-related NCCP group than the non-GERD-related NCCP group (P = 0.002), whereas it did not differ between the 2 groups at the proximal esophagus. In conclusion, the mucosal integrity is impaired at the proximal esophagus in patients with non-GERD-related NCCP, which might be the pathogenic mechanism of NCCP. PMID:26705212

Chlamydia antibody test (CAT) has been proposed to predict tubal disease. A correlation between CA-125 and the extent of endometriosis has been found by others. In this study we explored whether a combination of the two tests adds to the predictive value of the individual tests for predicting tubal disease or endometriosis. We also used the combination of tests as a new index test to screen for severe pelvic pathology. This retrospective study compares the findings of 240 laparoscopies with the serological test results. Findings were classified according to the existing ASRM scoring systems for adnexal adhesions, distal tubal occlusion and endometriosis. Severe pelvic pathology was defined as the presence of ASRM classes III and IV tubal disease or ASRM classes III and IV endometriosis. The predictive value was calculated for both tests separately and for the combined test. The combined test was positive if at least one test result was abnormal (CAT positive and/or CA-125 > or =35 IU/ml). 67/240 women had tubal disease, 81/240 had some degree of endometriosis. The odds ratios (ORs) of the CAT and the combined test to diagnose severe tubal disease were 6.6 (2.6-17.0) and 7.3 (2.9-19.3), respectively. The ORs of the CA-125 and the combined test to diagnose severe endometriosis were 15.6 (6.2-40.2) and 3.0 (1.2-8.0), respectively. Severe pelvic pathology was present in 65/240 women (27%). The ORs for severe pelvic pathology of the CAT, CA-125 and the combined test were 2.5 (1.4-5.3), 4.9 (1.9-9.6) and 6.6 (3.3-13.4), respectively. If the combined test was normal 15 out 131 women (11%) were shown to have severe pelvic pathology. The combined test adds hardly anything to the predictive value of CAT alone to diagnose severe tubal disease. The combined test is better than the CAT to predict severe pelvic pathology, but is not significantly better than the CA-125. If both the CAT and CA-125 are normal one could consider not performing a laparoscopy.

The aim of this study was to investigate the added value of SPECT/spiral CT versus SPECT or CT alone in the differential diagnosis of solitary skeletal lesions. This was a retrospective study on a total of 69 patients who had a solitary skeletal "hot spot" that could not be definitively diagnosed using planar scintigraphy. Thus, SPECT/spiral CT was performed on the indeterminate lesions. SPECT, CT and SPECT/spiral CT images were independently interpreted by two experienced doctors who have both identification of CT and nuclear medicine. Each lesion was graded on a 4-point diagnostic scale (1: benign, 2: likely benign, 3: likely malignant, 4: malignant). The final diagnosis of each lesion was based on pathological confirmation after surgery within 3 weeks of the bone scan. Final diagnoses based on the pathological results revealed that 43 of the 69 patients were diagnosed with malignancy, and the remaining 26 patients were diagnosed as having benign lesions. For SPECT and CT scans, both of the reviewers rated 55.1 % (38/69) and 37.7 % (26/69) of lesions as equivocal, with the help of SPECT/CT, 33.3 % (23/69) of lesions were rated as equivocal. The diagnostic accuracies of SPECT, CT alone and SPECT/CT were 66.7 % (46/69) ,82.6 % (57/69) and 85.5 %(59/69), respectively. The kappa scores for the degree of agreement between SPECT, CT alone or SPECT/CT with pathological results were 0.185 (p = 0.054) , 0.612 (p < 0.001) and 0.671 (p < 0.001), respectively. Compared with SPECT or imaging alone, SPECT/spiral CT imaging was more accurate and valuable in the differential diagnosis of solitary skeletal lesions and resulted in significantly fewer equivocal findings.

The effectiveness of the concomitant repair of hiatal hernia (HHR) during laparoscopic sleeve gastrectomy (LSG) in reducing gastroesophageal reflux disease (GERD) symptoms is still unclear. The aim of this study is to assess the effect of concomitant HHR on postoperative GERD symptoms in our patient population. A retrospective review of patients who underwent LSG with or without HHR between 2011and 2014 was performed. Pre- and postoperative GERD symptoms were assessed at different time intervals until a maximum of 2 years after the surgery. The study included 165 patients; 76 (46%) underwent LSG with concomitant HHR (group A) while the rest underwent only LSG (group B). Baseline GERD complaints were more prevalent in group A (61.8 vs 41.6%, p = 0.04), in which 44 patients (57.9%) had evidence of hiatal hernia on preoperative EGD. In the remaining 32 patients, it was diagnosed intraoperatively. GERD symptoms did not significantly differ between the two groups after years 1 and 2. GERD remission was observed in 21.3% of the 76 patients who underwent concomitant HHR (group A) and in 29.7% of those who did not (group B) while new-onset GERD symptoms were reported in 12 patients (41.4%) in group A and in 24 patients (46.2%) in group B. Routine HHR at the time of LSG does not show an improvement in GERD symptoms. More prospective studies are needed to clarify the role of the routine dissection, identification, and repair of concomitant hiatal hernia during LSG.

Subvalvular aortic stenosis (SAS) and mitral dysplasia were diagnosed in an asymptomatic eight-week-old rottweiler. Clinical and pathological findings were compatible with a fixed and dynamic obstruction of the left ventricular outflow tract. Gross and microscopic pathological findings were consistent with the most severe form of SAS, described previously in Newfoundland dogs over six months of age. These observations demonstrate that very young asymptomatic puppies may suffer a severe complex form of SAS.

The reported incidence rate of occult thyroid carcinoma in patients operated for benign thyroid pathology has been much higher than expected in the last years,especially for multinodular goitre, which raises the question about which should the proper surgical management for these cases be. To assess the incidence rate of OTC in a single medium volume surgical center and to establish the correct indication for initial surgical management, as well as to identify the benign thyroid pathology most frequently associated with OTC. We also reviewed the relevant scientific literature on this topic. We conducted a retrospective study in the General Surgery Clinic of "Prof. dr. Agrippa Ionescu" Clinical Emergency Hospital, Bucharest, on a series of 145 patients who underwent surgical interventions for preoperatively diagnosed benign thyroid pathology over a ten year period, between 1st January 2002 - 31st December 2012. All cases of known thyroid cancer were excluded. Incidence rate of occult thyroid carcinoma in our series was 6.9 % (10 out of 145 patients), 80 % of them being diagnosed with multinodular goitre and two cases (20 %) with Hashimoto's lymphocytic thyroiditis. 6.8 % of all patients with multinodular goitre were found to present occult carcinoma,but this association was without statistical significance(p 0.05). Incidence rate of occult cancer among patients with Hashimoto thyroiditis was proved to be as high as 28.6%,statistically significant (p=0.020). The mean size of postoperatively diagnosed occult microcarcinoma was 7 mm, ranging between 3 mm and 14 mm, 90% of them being smaller than 1cm. Histologically, papillary microcarcinoma was found in all cases. The mean age of the patients diagnosed with occult microcarcinoma was 47.8 years with majority of the female gender. The most frequent operation performed was total thyroidectomy (70.8%). Overall morbidity in our series was 6.9% with a 0.7 % mortality rate (1 case). In our opinion, primary total thyroidectomy

Gastroesophageal reflux disease (GERD) and/or hiatus hernia (HH) are one of the most common disorders of the upper gastrointestinal tract. Despite the positive effect of sleeve gastrectomy (SG) regarding weight loss and improvement in obesity co-morbidities, there are concerns about the development of de novo gastroesophageal reflux disease or worsening the existing GERD after this bariatric operation. Furthermore, controversy exists on the consequences of SG in lower esophageal sphincter function and about the ideal procedure when a hiatus hernia is preoperatively diagnosed or discovered during the laparoscopic SG. This review systematically investigates the incidence, the pathophysiology of GERD and/or HH in morbidly obese individuals before and after SG, and the treatment options for concomitant HH repair during laparoscopic sleeve gastrectomy.

Background/Aims Gastroesophageal reflux disease (GERD) is one of the main causes of chronic cough. We evaluated the role of microaspiration in the pathogenesis of reflux-related cough by determining the amount of lipid-laden macrophages (LLMs) in bronchoalveolar lavage (BAL) specimens. Methods A total of 161 cases of chronic cough were evaluated, and 36 patients (average age 48.2 years) were recruited for this single center prospective study. Patients with a history of smoking, angiotensin converting enzyme inhibitor usage, any abnormality on pulmonary function tests, abnormal chest X-rays, occupational or environmental exposures, or upper airway cough syndrome were excluded. GERD was evaluated by 24-hour esophageal impedance-pH monitoring. BAL specimens for LLM determination were obtained from 34 patients by flexible bronchoscopy. Results Patients with pathological intra-esophageal reflux according to multichannel intraluminal impedance and pH monitoring had higher LLM positivity in BAL specimens than patients without pathological reflux (8/14 in reflux positive group vs 1/22 in reflux negative group; P = 0.004). The BAL cell distribution was not different between the 2 groups (P = 0.574 for macrophages, P = 0.348 for lymphocytes, P = 0.873 for neutrophils and P = 0.450 for eosinophils). Conclusions Our results confirm the role of the microaspiration of refluxate in the pathogenetic mechanism of chronic cough. While bronchoscopy is indicated in patients with chronic cough, in addition to the routine airway evaluation, BAL and LLM detection should be performed. LLM can be used to diagnose aspiration in reflux-related chronic cough. Future studies are needed to evaluate the response to anti-reflux medications or surgery in patients with LLM positivity.

Orbital infections and inflammations include a broad spectrum of orbital diseases that can be idiopathic, infectious, from primary or secondary inflammatory processes. Being able to properly diagnose and manage these orbital diseases in a timely manner can avoid permanent vision loss and possibly save a patient's life. When clinicians are faced with such patients, quite often the exact diagnosis cannot be made just based on clinical examination, various laboratory tests and imaging are needed. Moreover, orbital biopsies with histopathological analyses are often required, especially for the atypical cases. Thus, it is important for the clinicians to be familiar with the pathological features and characteristics of these orbital diseases. This review provides a comprehensive update on the clinical and pathological diagnosis of these orbital infections and inflammations. PMID:22224014

Gastroesophageal reflux disease (GERD) is common in patients with obesity. Diagnosing GERD is important as bariatric operations have different influence on GERD. We assessed reflux symptoms and objective findings prior to surgery. Work-up included esophageal symptoms quantification by VAS-scores, esophagogastroduodenoscopy (EGD) and 24-h impedance-pH (imp-pH) monitoring off PPI therapy. Imp-pH was classified as abnormal if either %time pH<4 was abnormal, total number of reflux episodes was elevated or symptom index (SI) was positive. Among 100 consecutive patients (68F, age 40±11years, BMI 44.9±6.9kg/m 2 ) 54% reported heartburn and/or regurgitation, 71% had objective evidence of GERD (38% endoscopic lesions and 33% only abnormal imp-pH results). Imp-pH was superior to EGD in identifying GERD (sensitivity 85% vs. 54%, p<0.01). Symptomatic and asymptomatic patients had similar prevalence of esophageal lesions (37% vs. 39%) and abnormal imp-pH findings (68% vs. 50%). Sixty nine percent of patients with abnormal %time pH<4 had a normal number of reflux episodes. Half of patients with obesity reported typical GERD symptoms and >70% had evidence of GERD. Poor acid clearance was the main mechanisms. Since typical reflux symptoms don't predict objective findings, endoscopy and reflux monitoring should be part of the surgery work-up especially before restrictive procedures.

Background/Aims Available data about reflux patterns and symptom determinants in the gastroesophageal reflux disease (GERD) subtypes off proton pump inhibitor (PPI) therapy are lacking. We aimed to evaluate reflux patterns and determinants of symptom perception in patients with GERD off PPI therapy by impedance-pH monitoring. Methods We retrospectively reviewed the impedance-pH data in patients diagnosed as GERD based on results of impedance-pH monitoring, endoscopy and/or typical symptoms. The characteristics of acid and weakly acidic reflux were evaluated. Symptomatic and asymptomatic reflux were compared according to GERD subtypes and individual symptoms. Results Forty-two patients (22 males, mean age 46 years) were diagnosed as GERD (17 erosive reflux disease, 9 pH(+) non-erosive reflux disease [NERD], 9 hypersensitive esophagus and 7 symptomatic NERD). A total of 1,725 reflux episodes were detected (855 acid [50%], 857 weakly acidic [50%] and 13 weakly alkaline reflux [< 1%]). Acid reflux was more frequently symptomatic and bolus clearance was longer compared with weakly acidic reflux. In terms of globus, weakly acidic reflux was more symptomatic. Symptomatic reflux was more frequently acid and mixed reflux; these associations were more pronounced in erosive reflux disease and symptomatic NERD. The perception of regurgitation was related to acid reflux, while that of globus was more related to weakly acidic reflux. Conclusions In patients not taking PPI, acid reflux was more frequently symptomatic and had longer bolus clearance. Symptomatic reflux was more frequently acid and mixed type; however, weakly acidic reflux was associated more with globus. These data suggest a role for impedance-pH data in the evaluation of globus.

The paper is describing the design and the performance of the computerized system, from its introduction in 1982 until the present day. The first device, using the MUMPS language on a mini-computer, followed by a VAX computer with terminals have been replaced in 1996 by an application program, using ORACLE, based on the client-server concept. The content and the particularities of the different data groups are discussed, concerning the functional components of the data bank: 'PATIENTS', 'SPECIMEN', 'SENDERS', 'REPORT' and 'DIAGNOSES'. By means of examples, we demonstrate the chronological evolution of the registration of persons, the distribution of the diagnoses according to the organ systems, the possibilities to combine various lesions and an algorithm to assure that a given lesion is registered only once per patient. In first place, the efficiency and the reliability of manual coding by a pathologist using the Systematized Nomenclature of Medicine (SNOMED; 2nd edition [1979/1982]) is discussed. The data bank currently contains 530,000 diagnoses, distributed among on SNOMED's five main modules, obtained from 1500 autopsies, 140,000 surgical and 180,000 cytological specimens. Concluding the article, an analysis is made of desirable developments in the future with the aim of a better integration of the acquired information in routine work and an enhanced use of the medical content for epidemiological research or statistical analysis.

The dual pathology consisting of hippocampal sclerosis plus focal cortical dysplasia (FCD) is often reported in patients with medication-resistant medial temporal lobe epilepsy (MTLE). To determine the histopathological changes that take place in the neocortex of patients with medication-resistant MTLE submitted to surgery and to evaluate the relation between the histopathological changes, pathological background and the clinical course of patients who had received surgical treatment. Tissue obtained by en bloc resection from the neocortex of 18 patients with MTLE refractory to medical treatment was processed histologically and a tailored temporal lobectomy was performed with electrocorticography. Dual pathology was diagnosed in 13 patients (72.2%). Imaging studies confirmed the existence of mesial sclerosis of the temporal in 100% of cases and there was no evidence of neocortical lesions. Histologically, 46.15% and 38.46% of the patients were diagnosed as belonging to FCD type 1a and FCD type 1b, respectively. Only one patient presented FCD type 2a. A statistically significant relation was found between the presence of dual pathology and the existence of an early precipitating injury (p = 0.04). One year after surgery, 72.7% (8/11) patients with dual pathology were classified as belonging to Engel class I. In patients with MTLE there are microscopic FCD-type alterations in the neocortex. There is an association between these alterations and the existence of an initial precipitating injury. Complete resection of the epileptogenic area, which is guaranteed by the lobectomy tailored by electrocorticography, allows patients to enjoy a favourable post-surgical progression one year after surgery.

A question arose in our practice of whether all cysts considered sebaceous should be sent for pathologic evaluation. To address this controversial topic, we performed a retrospective study of our single institution's histopathology database. A natural language search of the CoPath database across the institution was undertaken using the diagnosis of sebaceous cyst, epidermal cyst, epidermoid cyst, epithelial cyst, infundibular cyst, pilar cyst, trichilemmal cyst, and steatocystoma. A surgical pathologic review of all specimens with one of these preexcision diagnoses was included in the 15-year retrospective study of 1998 to 2013. All slides were confirmed to have undergone histopathologic review, and the preexcision diagnoses were compared with the postexcision diagnoses. Chart review was undertaken in instances of a diagnosis of malignancy. A total of 13,746 samples were identified. Forty-eight specimens had histopathologic diagnosis of malignancy, for an incidence of 0.3% and with the most common malignancy being squamous cell carcinoma. Chart review showed that for all cases, the surgeons reported uncertainty with regard to the diagnosis because of history or physical characteristics, or both. In addition, a comprehensive literature review showed results consistent with our data and illustrated 19 cases during the past 10 years in which most of the findings were squamous cell carcinoma. We propose the recommendation that routine pathologic evaluation of sebaceous cysts is necessary only when clinical suspicion exists.

Objective To define the scope and needs of computational pathology. Data Sources A meeting was convened in Boston, Massachusetts, in July 2014 prior to the annual Association of Pathology Chairs meeting, and it was attended by a variety of pathologists, including individuals highly invested in pathology informatics as well as chairs of pathology departments. Conclusions The meeting made recommendations to promote computational pathology, including clearly defining the field and articulating its value propositions; asserting that the value propositions for health care systems must include means to incorporate robust computational approaches to implement data-driven methods that aid in guiding individual and population health care; leveraging computational pathology as a center for data interpretation in modern health care systems; stating that realizing the value proposition will require working with institutional administrations, other departments, and pathology colleagues; declaring that a robust pipeline should be fostered that trains and develops future computational pathologists, for those with both pathology and non-pathology backgrounds; and deciding that computational pathology should serve as a hub for data-related research in health care systems. The dissemination of these recommendations to pathology and bioinformatics departments should help facilitate the development of computational pathology. PMID:26098131

Acromioclavicular joint (ACJ) dislocations are common injuries of the shoulder associated with physical activity. The diagnosis of concomitant injuries proves complicated due to the prominent clinical symptoms of acute ACJ dislocation. Because of increasing use of minimally invasive surgery techniques concomitant pathologies are diagnosed more often than with previous procedures. The aim of this study was to identify the incidence of concomitant intraarticular injuries in patients with high-grade acromioclavicular separation (Rockwood type III - V) as well as to reveal potential risk constellations. The concomitant pathologies were compiled during routine arthroscopically assisted treatment in altogether 163 patients (147 male; 16 female; mean age 36.8 years) with high-grade acromioclavicular separation (Rockwood type III: n = 60; Rockwood type IV: n = 6; Rockwood type V: n = 97). Acromioclavicular separation occurred less often in women than men (1:9). In patients under 35, the most common cause for ACJ dislocation was sporting activity (37.4%). Rockwood type V was observed significantly more often than the other types with 57.5% (Rockwood type III = 36.8%, Rockwood type IV 3.7%). Concomitant pathologies were diagnosed in 39.3% of the patients with that number rising to as much as 57.3% in patients above 35 years. Most common associated injuries were rotator cuff injuries (32.3%), chondral defects (30.6%) and SLAP-lesions (22.6%). Of all patients, 8.6% needed additional reconstructive surgery. Glenohumeral injuries are a much more common epiphenomenon during acromioclavicular separation than previously ascertained. High risk group for accompanying injuries are patients above 35 years with preexisting degenerative disease. The increasing use of minimally invasive techniques allows for an easier diagnosis and simultaneous treatment of the additional pathologies.

The study aimed to determine the characteristics and circumstances of cases sudden or unnatural death (n = 61) with evidence of pathological hoarding, their major organ pathology and toxicology. The mean age was 65·8 yrs (a mean of 16.1 years of potential life lost), 62·3% were male, and 28·2% were obese. 95·1% lived alone, and 96·7% died in their residence, with no medical intervention. In all cases severe squalor and extensive hoarding were noted. The direct cause of death was attributed to disease in 75·4%, heart disease being a significant factor in 52·5%. Accidents causing death directly related to hoarding occurred in two cases. Autopsy revealed extensive pathology: severe coronary artery narrowing (42·4%), myocardial replacement fibrosis (44·1%), emphysema (39·0%), nephrosclerosis (46·6%). Signs of hypothermia were present in 14·8%, and diabetes was diagnosed in 21·3%. The most commonly detected substance was alcohol (32·1%). Medications for heart disease (5·4%) or diabetes (7·1%) were rare. The overall clinical picture was of an isolated group, with a heavy burden of physical disease and, in all probability, a high level of psychiatric disorders, who died alone in their homes.

Global developmental delay (GDD) and intellectual disability (ID) are frequent reasons for consultation in paediatric neurology departments. Nowadays, array comparative genomic hybridisation (array-CGH) is one of the most widely used techniques for diagnosing these disorders. Our purpose was to determine the phenotypic features associated with pathological results in this genetic test. We conducted a blind study of the epidemiological, clinical, anthropometric, and morphological features of 80 patients with unexplained ID to determine which features were associated with pathological results in array-CGH. Pathological results were found in 27.5% of the patients. Factors associated with pathological results in array-CGH were a family history of GDD/ID (OR = 12.1), congenital malformations (OR = 5.33), having more than 3 facial dysmorphic features (OR = 20.9), and hypotonia (OR = 3.25). Our findings are consistent with those reported by other published series. We therefore conclude that the probability of having pathological results in array-CGH increases with the presence of any of the features mentioned above in patients with ID/GDD.

Abstract Blunt chest traumas mostly occur due to car accidents and can cause many cardiac complications such as septal rupture, free-wall rupture, coronary artery dissection or thrombosis, heart failure, arrhythmias, and chordae and papillary muscle rupture. One of the most serious complication is tricuspid regurgitation (TR), which can be simply diagnosed by physical examination and confirmed by echocardiography. We describe a 48-year-old female patient, diagnosed with severe TR 13 years after a blunt chest trauma due to a car accident. TR was diagnosed with transthoracic echocardiography and three dimensional transthoracic echocardiography had defined the exact pathology of the tricuspid valve. The patient underwent successful surgery with bioprosthetic valve implantation and was discharged at 6th postoperative day without any complication. The patient had no problem according to the follow-up one month and six months after operation. PMID:26157464

Dental erosion (DE) is the loss of the hard tissues of the tooth produced by the action of gastric juice, pepsin and acid on the dental enamel, its frequency ranges from 5 to 53.41 %. In Mexico there are no reports on the frequency and possible association. To establish the prevalence of dental erosion and its relationship to GERD. Prospective, observational, descriptive and comparative study was conducted in 60 patients diagnosed with GERD and 60 healthy patients at the Institute of Medical and Biological Research of the Universidad Veracruzana in Veracruz city. Anthropometric characteristics, dietary habits, oral hygiene, alcohol consumption, smoking, ED index and Index of decayed/missing dental pieces/sealed and correlation between severity of ED and GERD were analyzed. 78.67 % of patients with GERD had ED, 23.33 % corresponded to grade 0, 41.67 % to N1, N2 and 23.33 % to 11.67 % to N3. Predominance of females (2,3:1). The mean age was 50.92 +/- 13.52 years. The severity of dental erosion was significantly related to the severity of reflux, halitosis, CPO index and poor eating habits. There was no statistically significant difference in the other variables analyzed. Dental erosion has a high frequency in patients with GERD and reflux characteristics are directly related to their severity and therefore should be considered as a manifestation of GERD extraesophageal.

Expert algorithms in the field of intelligent patient monitoring have rapidly revolutionized patient care thereby improving patient safety. Patient monitoring during anesthesia requires cautious attention by anesthetists who are monitoring many modalities, diagnosing clinically critical events and performing patient management tasks simultaneously. The mishaps that occur during day-to-day anesthesia causing disastrous errors in anesthesia administration were classified and studied by Reason [1]. Human errors in anesthesia account for 82% of the preventable mishaps [2]. The aim of this paper is to develop a clinically useful diagnostic alarm system for detecting critical events during anesthesia administration. The development of an expert diagnostic alarm system called ;RT-SAAM' for detecting critical pathological events in the operating theatre is presented. This system provides decision support to the anesthetist by presenting the diagnostic results on an integrative, ergonomic display and thus enhancing patient safety. The performance of the system was validated through a series of offline and real-time testing in the operation theatre. When detecting absolute hypovolaemia (AHV), moderate level of agreement was observed between RT-SAAM and the human expert (anesthetist) during surgical procedures. RT-SAAM is a clinically useful diagnostic tool which can be easily modified for diagnosing additional critical pathological events like relative hypovolaemia, fall in cardiac output, sympathetic response and malignant hyperpyrexia during surgical procedures. RT-SAAM is currently being tested at the Auckland City Hospital with ethical approval from the local ethics committees.

To estimate excess health care expenditures associated with gastroesophageal reflux disease (GERD) among elderly individuals with chronic obstructive pulmonary disease (COPD) and examine the contribution of predisposing characteristics, enabling resources, need variables, personal health care practices, and external environment factors to the excess expenditures, using the Blinder-Oaxaca linear decomposition technique. This study utilized a cross-sectional, retrospective study design, using data from multiple years (2006-2009) of the Medicare Current Beneficiary Survey linked with fee-for-service Medicare claims. Presence of COPD and GERD was identified using diagnoses codes. Health care expenditures consisted of inpatient, outpatient, prescription drugs, dental, medical provider, and other services. For the analysis, t-tests were used to examine unadjusted subgroup differences in average health care expenditures by the presence of GERD. Ordinary least squares regressions on log-transformed health care expenditures were conducted to estimate the excess health care expenditures associated with GERD. The Blinder-Oaxaca linear decomposition technique was used to determine the contribution of predisposing characteristics, enabling resources, need variables, personal health care practices, and external environment factors, to excess health care expenditures associated with GERD. Among elderly Medicare beneficiaries with COPD, 29.3% had co-occurring GERD. Elderly Medicare beneficiaries with COPD/GERD had 1.5 times higher ($36,793 vs $24,722 [P<0.001]) expenditures than did those with COPD/no GERD. Ordinary least squares regression revealed that individuals with COPD/GERD had 36.3% (P<0.001) higher expenditures than did those with COPD/no GERD. Overall, 30.9% to 43.6% of the differences in average health care expenditures were explained by differences in predisposing characteristics, enabling resources, need variables, personal health care practices, and external

Gastro-Esophageal Reflux in Children.

Gastro-esophageal reflux (GER) is common in infants and children and has a varied clinical presentation: from infants with innocent regurgitation to infants and children with severe esophageal and extra-esophageal complications that define pathological gastro-esophageal reflux disease (GERD). Although the pathophysiology is similar to that of adults, symptoms of GERD in infants and children are often distinct from classic ones such as heartburn. The passage of gastric contents into the esophagus is a normal phenomenon occurring many times a day both in adults and children, but, in infants, several factors contribute to exacerbate this phenomenon, including a liquid milk-based diet, recumbent position and both structural and functional immaturity of the gastro-esophageal junction. This article focuses on the presentation, diagnosis and treatment of GERD that occurs in infants and children, based on available and current guidelines.

Background: Corticobasal syndrome (CBS) can be associated with different underlying pathologies that are difficult to predict based on clinical presentation. The aim of this study was to determine whether patterns of atrophy on imaging could be useful to help predict underlying pathology in CBS. Methods: This was a case-control study of 24 patients with CBS who had undergone MRI during life and came to autopsy. Pathologic diagnoses included frontotemporal lobar degeneration (FTLD) with TDP-43 immunoreactivity in 5 (CBS-TDP), Alzheimer disease (AD) in 6 (CBS-AD), corticobasal degeneration in 7 (CBS-CBD), and progressive supranuclear palsy in 6 (CBS-PSP). Voxel-based morphometry and atlas-based parcellation were used to assess atrophy across the CBS groups and compared to 24 age- and gender-matched controls. Results: All CBS pathologic groups showed gray matter loss in premotor cortices, supplemental motor area, and insula on imaging. However, CBS-TDP and CBS-AD showed more widespread patterns of loss, with frontotemporal loss observed in CBS-TDP and temporoparietal loss observed in CBS-AD. CBS-TDP showed significantly greater loss in prefrontal cortex than the other groups, whereas CBS-AD showed significantly greater loss in parietal lobe than the other groups. The focus of loss was similar in CBS-CBD and CBS-PSP, although more severe in CBS-CBD. Conclusions: Imaging patterns of atrophy in CBS vary according to pathologic diagnosis. Widespread atrophy points toward a pathologic diagnosis of FTLD-TDP or AD, with frontotemporal loss suggesting FTLD-TDP and temporoparietal loss suggesting AD. On the contrary, more focal atrophy predominantly involving the premotor and supplemental motor area suggests CBD or PSP pathology.

Majewski osteodysplastic primordial dwarfism type II (MOPDII) is characterized by severe prenatal and postnatal growth failure with microcephaly, characteristic skeletal dysplasia, an increased risk for cerebrovascular disease, and insulin resistance. MOPDII is caused by mutations in the pericentrin (PCNT) gene and is inherited in an autosomal-recessive manner. This study aimed to determine the incidence of hip pathology in patients with molecularly confirmed MOPDII and to describe the functional outcomes of surgical treatment. Thirty-three enrolled patients had a clinical diagnosis of MOPDII. Biallelic PCNT mutations or absent pericentrin protein was confirmed in 25 of these patients. Twelve patients (7 female) had appropriate clinical and radiographic records at this institution and were included in this study. The data collected included age at presentation, age at surgery, sex, body weight and height, weight-bearing status at diagnosis, and the clinical examination. Four patients (31%) had coxa vara: 3 unilateral and 1 bilateral. Three unilateral patients had in situ pinning at a mean age 4 years. The patient with bilateral coxa vara had valgus osteotomy at the age of 5 years. Two children had bilateral hip dysplasia and subluxation with no surgery. One patient had bilateral developmental hip dislocations. The patient was treated by open reduction-spica cast and 2 years after surgery, coxa valga was noted. Another patient was diagnosed at an age of 12 years with bilateral avascular necrosis of the hips. Four patients did not have hip pathology. Hip pathology is common among children with MOPDII; coxa vara is the most frequent diagnosis. Routine clinical and radiographic hip evaluation is important. The capital femoral epiphysis appears to slip down along the shaft, giving the appearance of a proximal femoral epiphysiolysis. A hip diagnosed with slipped capital femoral epiphysis in early life may progress to severe coxa vara. Level IV.

Is GERD a Factor in Osteonecrosis of the Jaw? Evidence of Pathology Linked to G6PD Deficiency and Sulfomucins

PubMed Central

Swanson, Nancy L.; Li, Chen

2016-01-01

Osteonecrosis of the jaw (ONJ), a rare side effect of bisphosphonate therapy, is a debilitating disorder with a poorly understood etiology. FDA's Adverse Event Reporting System (FAERS) provides the opportunity to investigate this disease. Our goals were to analyze FAERS data to discover possible relationships between ONJ and specific conditions and drugs and then to consult the scientific literature to deduce biological explanations. Our methodology revealed a very strong association between gastroesophageal reflux and bisphosphonate-induced ONJ, suggesting acidosis as a key factor. Overgrowth of acidophilic species, particularly Streptococcus mutans, in the oral microbiome in the context of insufficient acid buffering due to impaired salivary glands maintains the low pH that sustains damage to the mucosa. Significant associations between ONJ and adrenal insufficiency, vitamin C deficiency, and Sjögren's syndrome were found. Glucose 6 phosphate dehydrogenase (G6PD) deficiency can explain much of the pathology. An inability to maintain vitamin C and other antioxidants in the reduced form leads to vascular oxidative damage and impaired adrenal function. Thus, pathogen-induced acidosis, hypoxia, and insufficient antioxidant defenses together induce ONJ. G6PD deficiency and adrenal insufficiency are underlying factors. Impaired supply of adrenal-derived sulfated sterols such as DHEA sulfate may drive the disease process. PMID:27773962

Esophageal hypomotility and spastic motor disorders: current diagnosis and treatment.

PubMed

Valdovinos, Miguel A; Zavala-Solares, Monica R; Coss-Adame, Enrique

2014-11-01

Esophageal hypomotility (EH) is characterized by abnormal esophageal peristalsis, either from a reduction or absence of contractions, whereas spastic motor disorders (SMD) are characterized by an increase in the vigor and/or propagation velocity of esophageal body contractions. Their pathophysiology is not clearly known. The reduced excitation of the smooth muscle contraction mediated by cholinergic neurons and the impairment of inhibitory ganglion neuronal function mediated by nitric oxide are likely mechanisms of the peristaltic abnormalities seen in EH and SMD, respectively. Dysphagia and chest pain are the most frequent clinical manifestations for both of these dysfunctions, and gastroesophageal reflux disease (GERD) is commonly associated with these motor disorders. The introduction of high-resolution manometry (HRM) and esophageal pressure topography (EPT) has significantly enhanced the ability to diagnose EH and SMD. Novel EPT metrics in particular the development of the Chicago Classification of esophageal motor disorders has enabled improved characterization of these abnormalities. The first step in the management of EH and SMD is to treat GERD, especially when esophageal testing shows pathologic reflux. Smooth muscle relaxants (nitrates, calcium channel blockers, 5-phosphodiesterase inhibitors) and pain modulators may be useful in the management of dysphagia or pain in SMD. Endoscopic Botox injection and pneumatic dilation are the second-line therapies. Extended myotomy of the esophageal body or peroral endoscopic myotomy (POEM) may be considered in highly selected cases but lack evidence.

Background Depressed patients with comorbid personality pathology may fare worse in treatment for depression than those without this additional pathology, and comorbid personality pathology may be associated with superior response in one form of treatment relative to another, though recent findings have been mixed. We aimed to evaluate the effect of personality pathology on time to remission of patients randomly assigned to 1 of 2 treatment strategies for depression and to determine whether personality pathology moderated the effect of treatment assignment on outcome. Method Individuals undergoing an episode of unipolar major depression (n = 275) received interpersonal psychotherapy (Klerman, Weissman, Rounsaville, & Chevron, 1984) or selective serotonin reuptake inhibitor (SSRI) pharmacotherapy for depression. Depressive symptoms were measured with the HRSD-17. Remission was a mean HRSD-17 score of 7 or below over a period of 3 weeks. Personality disorders were measured according to SCID-II diagnoses, and personality pathology was measured dimensionally by summing the positive probes on the SCID-II. Results The presence of at least 1 personality disorder was not a significant predictor of time to remission, but a higher level of dimensionally measured personality pathology and the presence of borderline personality disorder were associated with a longer time to remission. Personality pathology did not moderate the effect of treatment assignment on time to remission. Conclusions The findings suggest that depressed individuals with comorbid personality pathology generally fare worse in treatment for depression, although in this report, the effect of personality pathology did not differ by the type of treatment received.

Digital pathology represents a transformative technology that impacts dermatologists and dermatopathologists from residency to academic and private practice. Two concerns are accuracy of interpretation from whole-slide images (WSI) and effect on workflow. Studies of considerably large series involving single-organ systems are lacking. To evaluate whether diagnosis from WSI on a digital microscope is inferior to diagnosis of glass slides from traditional microscopy (TM) in a large cohort of dermatopathology cases with attention on image resolution, specifically eosinophils in inflammatory cases and mitotic figures in melanomas, and to measure the workflow efficiency of WSI compared with TM. Three dermatopathologists established interobserver ground truth consensus (GTC) diagnosis for 499 previously diagnosed cases proportionally representing the spectrum of diagnoses seen in the laboratory. Cases were distributed to 3 different dermatopathologists who diagnosed by WSI and TM with a minimum 30-day washout between methodologies. Intraobserver WSI/TM diagnoses were compared, followed by interobserver comparison with GTC. Concordance, major discrepancies, and minor discrepancies were calculated and analyzed by paired noninferiority testing. We also measured pathologists' read rates to evaluate workflow efficiency between WSI and TM. This retrospective study was caried out in an independent, national, university-affiliated dermatopathology laboratory. Intraobserver concordance of diagnoses between WSI and TM methods and interobserver variance from GTC, following College of American Pathology guidelines. Mean intraobserver concordance between WSI and TM was 94%. Mean interobserver concordance was 94% for WSI and GTC and 94% for TM and GTC. Mean interobserver concordance between WSI, TM, and GTC was 91%. Diagnoses from WSI were noninferior to those from TM. Whole-slide image read rates were commensurate with WSI experience, achieving parity with TM by the most experienced

Ovarian cancer has one of the highest death/incidence rates and is commonly diagnosed at an advanced stage. In the recent WHO classification, new histotypes were classified which respond differently to chemotherapy. The e-standardized synoptic cancer pathology reports offer the clinicians essential and reliable information. The aim of our project was to develop an e-template for the standardized synoptic pathology reporting of ovarian carcinoma [based on the checklist of the College of American Pathologists (CAP) and the recent WHO/FIGO classification] to introduce a uniform and improved quality of cancer pathology reports. A functional and qualitative evaluation of the synoptic reporting was performed. An indispensable module for e-synoptic reporting was developed and integrated into the Hospital Information System (HIS). The electronic pathology system used a standardized structure with drop-down lists of defined elements to ensure completeness and consistency of reporting practices with the required guidelines. All ovarian cancer pathology reports (partial and final) with the corresponding glass slides selected from a 1-year current workflow were revised for the standard structured reports, and 42 tumors [13 borderline tumors and 29 carcinomas (mainly serous)] were included in the study. Analysis of the reports for completeness against the CAP checklist standard showed a lack of pTNM staging in 80% of the partial or final unstructured reports; ICD-O coding was missing in 83%. Much less frequently missed or unstated data were: ovarian capsule infiltration, angioinvasion and implant evaluation. The e-records of ovarian tumors were supplemented with digital macro- and micro-images and whole-slide images. The e-module developed for synoptic ovarian cancer pathology reporting was easily incorporated into HIS.CGM CliniNet and facilitated comprehensive reporting; it also provided open access to the database for concerned recipients.

To study the clinical and pathological features of Alport syndrome in children. The clinical and histopathological data of 10 hospitalized children with Alport syndrome from February 2007 to February 2009 were retrospectively reviewed. There were 7 males and 3 females, with the age ranging from 2 years to 6 years and 7 months (mean 3 years and 2 months). Five of 10 cases had positive family history. X-linked dominant inheritance Alport syndrome was diagnosed in 8 cases, and autosomal recessive inheritance Alport syndrome in 2 cases. Recurrent gross hematuria was found in 5 cases, hematuria and proteinuria in 3 cases, massive proteinuria in 1 case, and nephritic syndrome in 1 case. Under the light microscope, 8 cases presented with mesangial proliferation glomerulonephritis, and 2 cases with focal segmental glomerulosclerosis. Immunofluorescence assay showed that all cases had IgM deposition in glomerulus. Only 1 case showed typical glomerular basement membrane (GBM) pathological changes. All cases showed abnormal alpha-chain distribution in renal collagen IV. The children with Alport syndrome have diverse clinical manifestations. Characteristic histopathological presentations could not be found under a light microscope, mesangial proliferation glomerulonephritis is the dominant pathological change, and IgM deposition in glomerulus is common. The GBM pathological change in children is not common. Immunofluorescence assay of alpha-chain in collagen IV is needed for the diagnosis of Alport syndrome.

Lymphatic disease is a rarely cause of some very unspecific genitourinary manifestations, assuming a diagnostic challenge in most cases. The aim of this paper is to warn about the possible etiology of these urological lymphatic presentations and discuss its management. Retrospective review of clinical data in pediatric patients with urological pathology of lymphatic origin between 2008-2014. Three patients, two boys and a girl, were included. The complaints were: redundant prepuce, inguinal scrotal tumor and urinary incontinence. Clinical, diagnosis and treatment protocol is described. The first case is a male with genital lymphedema presented at birth as a redundant prepuce and the subsequent emergence of lower limb lymphedema, treated with compression bandages. The second case, a groin lymphangioma which debuted as a sudden painless inguinal tumor simulating a cord cyst, it was sclerosed and treated with OK- 432. Finally, a preteen who consulted for involuntary leakage of urine, genital lymphedema likely primary cause (lymphodisplasia) or malformation was diagnosed, which improved with two Lipiodol® embolization. Genitourinary manifestations can be the debut of more complex lymphatic pathology, so it is necessary to consider this cause, uncommon and nonspecific. Its management must be conservative initially by compression bandages, OK-432 or embolization with Lipiodol®.

Following up on the largest case-control study of malignant mesothelioma yet performed, investigators at the London School of Hygiene and Tropical Medicine assessed 1732 male and 670 female cases as of May 2013. Epidemiological findings of a subset of these were published previously, excluding patients who died or who refused to be interviewed. Pathology reports were collected for subjects, including those both eligible and ineligible for epidemiology study based on vital status. The current investigation examined 860 cases having pathology reports available. Sixty-one cases were diagnosed using cytology only, often with equivocal diagnoses, while 799 reported at least a biopsy of the tumor. Of these, 748 had pathology sufficiently detailed for evaluation. These reports were examined for basis of diagnosis, differences between study cases and ineligible cases, pathology characteristics, and immunohistochemical and other tests used. The most prominent subtype was epithelioid (64% of study cases but only 49% of ineligible cases). Biphasic subtype was present in 10% of study cases and 16% of those ineligible. Sarcomatoid subtype was present in 7% of study cases and 19% of ineligible cases, most of whom died. Twelve percent of study cases displayed no specified subtype, versus 7% of ineligible cases. Of recorded immunohistochemical stains specific for mesothelial cell origin, calretinin (95%) and CK 5/6 or CK5 alone (84%) were by far the most common. Calretinin and CK 5/6 or CK 5 alone were also most sensitive and positive in 92% of cases presenting with surgical pathology report. Ninety percent of cases had at least one immunohistochemical marker for possible lung carcinoma applied, with BER-Ep4 and TTF-1 the most frequent at 68% and CEA at 58%. TTF-1 and CEA were positive in 1% or less of cases. Patterns of use and positive and negative results for each of these as well as other immunohistochemical stains are presented and discussed, along with a brief historical

Objectives: To investigate the clinical, pathological, and sonographic characteristics of unexpected gallbladder carcinoma (UGC). Methods: Of 5424 patients who had undergone cholecystectomy from December 2006 to October 2013, 54 patients with primary gallbladder carcinomas confirmed by pathological diagnosis were identified. The patients were divided into two groups: diagnosed before operation (n=34) and UGC groups (n=20), of whom the clinical, pathological, and sonographic characteristics were compared. Results: No significant differences in age, gender, location of lesion, histological type, length of the gallbladder, existence of biliary sludge, and intestinal gas interference between the two groups were found (all P>0.05). The clinical symptoms, laboratory abnormalities, tumor markers, coexisting gallbladder stones, lesion size, lesion type, degree of differentiation, and tumor staging showed statistically significant differences between the two groups (all P<0.05). On ultrasound, the width of the gallbladder, gallbladder wall thickness, vascularity on color Doppler ultrasound, and bile volume in the gallbladder showed significant differences (all P<0.05). Conclusions: UGCs are commonly found at an early stage, often well-differentiated, wall thickened, and are generally accompanied with cholelithiasis. UGCs should be taken into consideration in cases with cholelithiasis or small gallbladder on ultrasound. PMID:26379911

Neuropsychiatric symptoms are common manifestations of Alzheimer's disease (AD). A number of studies have targeted psychosis, i.e., hallucinations and delusions in AD, but few have assessed agitation/aggression in AD. To investigate the risk factors and pathological substrates associated with presence [A(+)] and absence [A(-)] of agitation/aggression (A) in autopsy-confirmed AD. Data was collected from the UDS data as of 2015 on the NACC database. Patients were stratified as intermediate (IAD) or high (HAD) pathological load of AD. Clinical diagnoses were not considered; additional pathological diagnoses were treated as variables. Analysis of data did not include a control group or corrections for multiple comparisons. 1,716 patients met the eligibility criteria; 31.2% of the IAD and 47.8% of the HAD patients were A(+), indicating an association with severity of pathology (p = 0.001). Risk factors for A(+) included: age at initial visit, age at death, years of education, smoking (in females), recent cardiac events (in males), and clinical history of traumatic brain injury (TBI) (in males). A history of hypertension was not related to A(+). In terms of comorbidity, clinical diagnosis of Lewy body dementia syndrome was associated with A(+) but the association was not confirmed when pathological diagnosis based on demonstration of Lewy bodies was used as the criterion. The additional presence of phosphorylated TDP-43, but not tau pathologies, was associated with A(+)HAD. Vascular lesions, including lacunes, large arterial infarcts, and severity of atherosclerosis were negatively associated with A(+). Associated symptoms included delusions, hallucinations, and depression, but not irritability, aberrant motor behavior, sleep and night time behavioral changes, or changes in appetite and eating habits. Smoking, TBI, and phosphorylated TDP-43 are associated with A(+)AD in specific groups, respectively. A(+) is directly associated with AD pathology load and inversely

To the best of the authors' knowledge, this study is the first to evaluate the olfactory function of adult patients diagnosed with GERD. The results revealed that adults with GERD have diminished olfactory function. This study aimed to evaluate the olfactory abilities of subjects using the 'Sniffin' Sticks' olfactory test. A total of 35 men and women aged 18-60 years with a diagnosis of GERD and 45 healthy controls were included in the study. The Sniffin' Sticks olfactory test results of the two groups were compared, and the relationship between the study findings and the olfactory parameters was evaluated. The odor threshold (10.1; 9.5, p = 0.016), odor identification (9.6; 8.1, p < 0.001), and odor discrimination (10.7; 8.9, p < 0.001) of the GERD group were significantly lower than those of the control group. A statistically significant positive correlation was detected between the accompanying chronic pharyngitis, chronic sinusitis, and odor parameters. A significant correlation was not detected between the laryngeal findings and the olfactory parameters.

Gastroesophageal reflux disease (GERD) is one of the most common diseases affecting patients worldwide, but its risk factors and causes are not clearly known. The aim of this study was to investigate the effect of coffee intake on GERD by a meta-analysis. We searched online published research databases such as PubMed, EMBASE, and Cochrane Library for studies that were published up to December 2012. These publications were reviewed by two independent authors, and studies that fulfilled the criteria were selected. Whenever there was a disagreement between the authors, a consensus was reached by discussion. Fifteen case-control studies were included in the final analysis. A meta-analysis showed that there was no significant association between coffee intake and GERD. The odds ratio was 1.06 (95% confidence interval, 0.94-1.19). In subgroup analyses in which the groups were subdivided based on the definition of GERD (diagnosed by endoscopy or by symptoms alone), only the endoscopy group showed a significantly higher odds ratio. In subgroup analyses in which the groups were subdivided based on the amount of coffee intake, quality of study, and assessment of exposure, there was no significant association between coffee intake and GERD. © 2013 Wiley Periodicals, Inc. and the International Society for Diseases of the Esophagus.

The underutilized practice of photographing anatomic pathology specimens from surgical pathology and autopsies is an invaluable benefit to patients, clinicians, pathologists, and students. Photographic documentation of clinical specimens is essential for the effective practice of pathology. When considering what specimens to photograph, all grossly evident pathology, absent yet expected pathologic features, and gross-only specimens should be thoroughly documented. Specimen preparation prior to photography includes proper lighting and background, wiping surfaces of blood, removing material such as tubes or bandages, orienting the specimen in a logical fashion, framing the specimen to fill the screen, positioning of probes, and using the right-sized scale.

Computed tomography (CT) of the brain is preferred study on neurological emergencies. Physicians use CT to diagnose various types of intracranial hematomas, including epidural, subdural and intracerebral hematomas according to their locations and shapes. We propose a novel method that can automatically diagnose intracranial hematomas by combining machine vision and knowledge discovery techniques. The skull on the CT slice is located and the depth of each intracranial pixel is labeled. After normalization of the pixel intensities by their depth, the hyperdense area of intracranial hematoma is segmented with multi-resolution thresholding and region-growing. We then apply C4.5 algorithm to construct a decision tree using the features of the segmented hematoma and the diagnoses made by physicians. The algorithm was evaluated on 48 pathological images treated in a single institute. The two discovered rules closely resemble those used by human experts, and are able to make correct diagnoses in all cases.

Uncovering the hidden: complexity and strategies for diagnosing latent tuberculosis.

Tuberculosis produces two clinical manifestations: active and latent (non-apparent) disease. The latter is estimated to affect one-third of the world population and constitutes a source of continued transmission should the disease emerge from its hidden state (reactivation). Methods to diagnose latent TB have been evolving and aim to detect the disease in people who are truly infected with M. tuberculosis , versus those where other mycobacteria, or even other pathologies not related to TB, are present. The current use of proteomic and transcriptomic approaches may lead to improved detection methods in the coming years.

Hippocampal sclerosis of aging (HS-Aging) neuropathology was observed in more than 15% of aged individuals in prior studies. However, much remains unknown about the clinical correlates of HS-Aging pathology or the association(s) between HS-Aging, Alzheimer's disease (AD), and frontotemporal lobar degeneration (FTLD) pathology. Clinical and comorbid pathological features linked to HS-Aging pathology were analyzed using National Alzheimer's Coordinating Center (NACC) data. From autopsy data extending back to 1990 (n = 9,817 participants), the neuropathological diagnoses were evaluated from American AD Centers (ADCs). Among participants who died between 2005-2012 (n = 1,422), additional analyses identified clinical and pathological features associated with HS-Aging pathology. We also compared cognitive testing and longevity outcomes between HS-Aging cases and a subsample with non-tauopathy FTLD (n = 210). Reporting of HS-Aging pathology increased dramatically among ADCs in recent years, to nearly 20% of autopsies in 2012. Participants with relatively "pure" HS-Aging pathology were often diagnosed clinically as having probable (68%) or possible (15%) AD. However, the co-occurrence of HS-Aging pathology and AD neuropathology (AD-NP) did not indicate any pattern of correlation between the two pathologies. Compared with other pathologies, participants with HS-Aging pathology had higher overall cognitive/functional ability (versus AD-NP) and verbal fluency (versus both AD-NP and FTLD) but similar episodic memory impairment at one clinic visit 2-5 years prior to death. Patients with HS-Aging live considerably longer than patients with non-tauopathy FTLD. We conclude that the manifestations of HS-Aging, increasingly recognized in recent years, probably indicate a separate disease process of direct relevance to patient care, dementia research, and clinical trials.

Endoscopic examination followed by tissue biopsy is the gold standard in the evaluation of lesions of the upper aerodigestive tract. However, it can be difficult to distinguish between healthy mucosa, dysplasia, and invasive carcinoma. Optical coherence tomography (OCT) is a non-invasive technique which acquires high-resolution, cross-sectional images of tissue in vivo. Integrated into a surgical microscope, it allows the intraoperative evaluation of lesions simultaneously with microscopic visualization. In a prospective case series, we evaluated the use of OCT integrated into a surgical microscope during microlaryngoscopy to help differentiating various laryngeal pathologies. 33 patients with laryngeal pathologies were examined with an OCT- microscope (OPMedT iOCT-camera, HS Hi-R 1000G-microscope, Haag-Streit Surgical GmbH, Wedel, Germany) during microlaryngoscopy. The suspected intraoperative diagnoses were compared to the histopathological reports of subsequent tissue biopsies. Hands-free non-contact OCT revealed high-resolution images of the larynx with a varying penetration depth of up to 1.2 mm and an average of 0.6 mm. Picture quality was variable. OCT showed disorders of horizontal tissue layering in dysplasias with a disruption of the basement membrane in carcinomas. When comparing the suspected diagnosis during OCT-supported microlaryngoscopy with histology, 79% of the laryngeal lesions could be correctly identified. Premalignant lesions were difficult to diagnose and falsely classified as carcinoma. OCT integrated into a surgical microscope seems to be a promising adjunct tool to discriminate pathologies of the upper aerodigestive tract intraoperatively. However, picture quality and penetration depth were variable. Although premalignant lesions were difficult to diagnose, the system proved overall helpful for the intraoperative discrimination of benign and malignant tumors. Further studies will be necessary to define its value in the future. Lasers

Despite of high rates of adverse childhood experiences (ACEs) in pathological gamblers, researchers have rarely studied which types of ACEs often co-occur and how these profiles of ACEs are related to current psychopathology. We aimed to identify profiles of ACEs in pathological gamblers and examined how these profiles were related to gambling-related characteristics and current general psychopathology. In 329 current or lifetime pathological gamblers, diagnosed with the Composite Diagnostic Interview for DSM-IV, 10 types of ACEs were measured using the Adverse Childhood Experiences Questionnaire. Global psychopathology was assessed using the Symptom Checklist SCL-27. ACE profiles were identified using latent class analysis. Differences between ACE profiles in gambling-related characteristics and global psychopathology were analyzed using MANOVA. We found that four out of five gamblers (n=257, 78.1%) reported at least one ACE. Four distinct ACE profiles were identified: 'Low ACE', 'High ACE', 'Physical and emotional abuse', and 'Neglect'. The number of the fulfilled pathological gambling criteria and the severity of current global psychopathology differed between the ACE profiles: Gamblers with a 'High ACE' profile fulfilled more pathological gambling criteria and showed a more severe current psychopathology than gamblers of the 'Low ACE' profile. Gamblers with a 'Physical and emotional abuse' or an 'Emotion neglect' profile showed an intermediate severity of psychopathology. Our findings indicate that four different ACE profiles can be distinguished in pathological gamblers that differed in their gambling-related characteristics and current psychopathology. Systematic assessment of profiles of ACEs in pathological gamblers may inform about the severity of current global psychopathology that might be important to be addressed in addition to gambling-specific treatment.

Emerging dilemmas in the diagnosis and management of gastroesophageal reflux disease

PubMed Central

Kahrilas, Peter; Yadlapati, Rena; Roman, Sabine

2017-01-01

Gastroesophageal reflux disease (GERD) is common, but less so than widely reported because of inconsistencies in definition. In clinical practice, the diagnosis is usually based on a symptom assessment without testing, and the extent of diagnostic testing pursued should be limited to that which guides management or which protects the patient from the risks of a potentially morbid treatment or an undetected early (or imminent) esophageal adenocarcinoma or which does both. When testing is pursued, upper gastrointestinal endoscopy is the most useful initial diagnostic test because it evaluates for the major potential morbidities (Barrett’s, stricture, and cancer) associated with GERD and facilitates the identification of some alternative diagnostic possibilities such as eosinophilic esophagitis. However, endoscopy is insensitive for diagnosing GERD because most patients with GERD have non-erosive reflux disease, a persistent diagnostic dilemma. Although many studies have tried to objectify the diagnosis of GERD with improved technology, this is ultimately a pragmatic diagnosis based on response to proton pump inhibitor (PPI) therapy, and, in the end, response to PPI therapy becomes the major indication for continued PPI therapy. Conversely, in the absence of objective criteria for GERD and the absence of apparent clinical benefit, PPI therapy is not indicated and should be discontinued. PPIs are well tolerated and safe, but nothing is perfectly safe, and in the absence of measurable benefit, even a miniscule risk dominates the risk-benefit assessment. PMID:29034088

McCune Albright syndrome (MAS) is a clinical association of endocrine and nonendocrine anomalies caused by postzygotic mutation of the GNAS1 gene, leading to somatic activation of the stimulatory α-subunit of G protein (Gsα). Important advances have been made recently in describing pathological characteristics of many MAS-affected tissues, particularly pituitary, testicular, and adrenal disease. Other rarer disease related features are emerging. The objective of the investigation was to study the pathological and genetic findings of MAS on a tissue-by-tissue basis in classically and nonclassically affected tissues. This was a comprehensive autopsy and genetic analysis. The study was conducted at a tertiary referral university hospital. An adult male patient with MAS and severe disease burden including gigantism was the subject of the study. Interventions included clinical, hormonal, and radiographic studies and gross and microscopic pathology analyses, conventional PCR, and droplet digital PCR analyses of affected and nonaffected tissues. Pathological findings and the presence of GNAS1 mutations were measured. The patient was diagnosed with MAS syndrome at 6 years of age based on the association of café-au-lait spots and radiological signs of polyostotic fibrous dysplasia. Gigantism developed and hyperprolactinemia, hypogonadotropic hypogonadism, and hyperparathyroidism were diagnosed throughout the adult period. The patient died at the age of 39 years from a pulmonary embolism. A detailed study revealed mosaiscism for the p.R201C GNAS1 mutation distributed across many endocrine and nonendocrine tissues. These genetically implicated tissues included rare or previously undescribed disease associations including primary hyperparathyroidism and hyperplasia of the thymus and endocrine pancreas. This comprehensive pathological study of a single patient highlights the complex clinical profile of MAS and illustrates important advances in understanding the

2017-01-01

Foot problems are a major cause of morbidity and mortality in elephants, but are underreported due to difficulties in diagnosis, particularly of conditions affecting the bones and internal structures. Here we evaluate post-mortem computer tomographic (CT) scans of 52 feet from 21 elephants (seven African Loxodonta africana and 14 Asian Elephas maximus), describing both pathology and variant anatomy (including the appearance of phalangeal and sesamoid bones) that could be mistaken for disease. We found all the elephants in our study to have pathology of some type in at least one foot. The most common pathological changes observed were bone remodelling, enthesopathy, osseous cyst-like lesions, and osteoarthritis, with soft tissue mineralisation, osteitis, infectious osteoarthriti, subluxation, fracture and enostoses observed less frequently. Most feet had multiple categories of pathological change (81% with two or more diagnoses, versus 10% with a single diagnosis, and 9% without significant pathology). Much of the pathological change was focused over the middle/lateral digits, which bear most weight and experience high peak pressures during walking. We found remodelling and osteoarthritis to be correlated with increasing age, more enthesopathy in Asian elephants, and more cyst-like lesions in females. We also observed multipartite, missing and misshapen phalanges as common and apparently incidental findings. The proximal (paired) sesamoids can appear fused or absent, and the predigits (radial/tibial sesamoids) can be variably ossified, though are significantly more ossified in Asian elephants. Our study reinforces the need for regular examination and radiography of elephant feet to monitor for pathology and as a tool for improving welfare. PMID:28123909

Digital slides obtained from whole slide imaging (WSI) platforms are typically viewed in two dimensions using desktop personal computer monitors or more recently on mobile devices. To the best of our knowledge, we are not aware of any studies viewing digital pathology slides in a virtual reality (VR) environment. VR technology enables users to be artificially immersed in and interact with a computer-simulated world. Oculus Rift is among the world's first consumer-targeted VR headsets, intended primarily for enhanced gaming. Our aim was to explore the use of the Oculus Rift for examining digital pathology slides in a VR environment. An Oculus Rift Development Kit 2 (DK2) was connected to a 64-bit computer running Virtual Desktop software. Glass slides from twenty randomly selected lymph node cases (ten with benign and ten malignant diagnoses) were digitized using a WSI scanner. Three pathologists reviewed these digital slides on a 27-inch 5K display and with the Oculus Rift after a 2-week washout period. Recorded endpoints included concordance of final diagnoses and time required to examine slides. The pathologists also rated their ease of navigation, image quality, and diagnostic confidence for both modalities. There was 90% diagnostic concordance when reviewing WSI using a 5K display and Oculus Rift. The time required to examine digital pathology slides on the 5K display averaged 39 s (range 10-120 s), compared to 62 s with the Oculus Rift (range 15-270 s). All pathologists confirmed that digital pathology slides were easily viewable in a VR environment. The ratings for image quality and diagnostic confidence were higher when using the 5K display. Using the Oculus Rift DK2 to view and navigate pathology whole slide images in a virtual environment is feasible for diagnostic purposes. However, image resolution using the Oculus Rift device was limited. Interactive VR technologies such as the Oculus Rift are novel tools that may be of use in digital pathology.

Digital pathology offers potential improvements in workflow and interpretive accuracy. Although currently digital pathology is commonly used for research and education, its clinical use has been limited to niche applications such as frozen sections and remote second opinion consultations. This is mainly due to regulatory hurdles, but also to a dearth of data supporting a positive economic cost-benefit. Large scale adoption of digital pathology and the integration of digital slides into the routine anatomic/surgical pathology "slide less" clinical workflow will occur only if digital pathology will offer a quantifiable benefit, which could come in the form of more efficient and/or higher quality care. As a large academic-based health care organization expecting to adopt digital pathology for primary diagnosis upon its regulatory approval, our institution estimated potential operational cost savings offered by the implementation of an enterprise-wide digital pathology system (DPS). Projected cost savings were calculated for the first 5 years following implementation of a DPS based on operational data collected from the pathology department. Projected savings were based on two factors: (1) Productivity and lab consolidation savings; and (2) avoided treatment costs due to improvements in the accuracy of cancer diagnoses among nonsubspecialty pathologists. Detailed analyses of incremental treatment costs due to interpretive errors, resulting in either a false positive or false negative diagnosis, was performed for melanoma and breast cancer and extrapolated to 10 other common cancers. When phased in over 5-years, total cost savings based on anticipated improvements in pathology productivity and histology lab consolidation were estimated at $12.4 million for an institution with 219,000 annual accessions. The main contributing factors to these savings were gains in pathologist clinical full-time equivalent capacity impacted by improved pathologist productivity and workload

To investigate the influence of proton pump inhibitors (PPIs) exposure on the diagnosis of Helicobacter pylori (H. pylori) gastritis and intestinal metaplasia. Chronic PPI use is associated with masking of H. pylori infection. Patients with H. pylori infection are predisposed to gastric and duodenal ulcers, and long-term infection with this organism has been associated with gastric mucosal atrophy and serious long-term complications, such as gastric lymphoma and adenocarcinoma. Three hundred patients diagnosed with gastritis between January 2008 and April 2010 were included in our study. The computerized medical database of these patients was reviewed retrospectively in order to assess whether the type of gastritis diagnosed (H. pylori vs non-H. pylori gastritis) is influenced by PPI exposure. H. pylori density was graded as low, if corresponding to mild density following the Updated Sydney System, or high, if corresponding to moderate or severe densities in the Updated Sydney System. Patients were equally distributed between males and females with a median age at the time of diagnosis of 50 years old (range: 20-87). The histological types of gastritis were classified as H. pylori gastritis (n = 156, 52%) and non-H. pylori gastritis (n = 144, 48%). All patients with non-H. pylori gastritis had inactive chronic gastritis. Patients with no previous PPI exposure were more likely to be diagnosed with H. pylori gastritis than those with previous PPI exposure (71% vs 34.2%, P < 0.001). Intestinal metaplasia was more likely to be detected in the latter patients (1.4% vs 6.5%, P = 0.023). Multivariate analysis has also demonstrated that in the presence of previous PPI exposure (OR = 0.217, 95%CI: 0.123-0.385), GERD (OR = 0.317, 95%CI: 0.132-0.763, P = 0.01), alcohol intake (OR = 0.396, 95%CI: 0.195-0.804, P = 0.01), the detection of H. pylori was less likely. Chronic use of PPIs may mask H. pylori infections promoting the diagnosis of non-H. pylori gastritis and leads to a

The management of benign intraductal papilloma diagnosed on core needle biopsy (CNB) remains unclear. This study was designed to evaluate factors predicting malignancy in patients diagnosed with benign papilloma without atypia at ultrasound-guided CNB and to develop a scoring system predicting malignancy based on clinical, radiological and pathological factors on further excisional biopsy. The study enrolled patients diagnosed with benign papillomas (including benign and atypical papillary lesions) at CNB. Multivariate analysis was used to identify relevant clinical, radiological and pathological factors that may predict malignancy. A total of 520 CNBs were diagnosed with benign or atypical papilloma. Of these, 452 were benign papilloma without atypia. Of the 250 lesions subsequently excised surgically from 234 women, 17 (6.8%) were diagnosed with malignancy. Multivariate analysis revealed that bloody nipple discharge, size on imaging ≥15 mm, BI-RADS≥4b, peripheral location and palpability were independent predictors of malignancy. A scoring system was developed based on logistic regression models and beta coefficients for each variable. The area under the ROC curve was 0.947 (95% CI: 0.913-0.981, p < 0.001) and a negative predictive value was 100%. In a validation set of 62 patients, an area under the ROC curve was 0.926 (95% CI: 0.857-0.995, p < 0.001). A scoring system predicting malignancy in patients diagnosed by CNB with benign papilloma without atypia was developed. This system was able to identify a subset of patients with lesions likely to be benign, indicating that imaging follow-up rather than surgical excision may be appropriate.

Extra-esophageal presentation of gastroesophageal reflux disease: new understanding in a new era.

PubMed

Martinucci, Irene; Albano, Eleonora; Marchi, Santino; Blandizzi, Corrado

2017-09-01

Associations of gastroesophageal reflux disease (GERD) with extraesophageal manifestations, such as chronic cough, asthma, and laryngitis, are reported frequently, and there is a strong evidence of biological plausibility in support of this relationship. On the other hand, extraesophageal reflux disease (EERD) is usually multifactorial in nature with reflux being just one of the several potential contributing cofactors. Moreover, the accuracy of currently available diagnostic tests for EERD is suboptimal, and therefore the causal relationship between GERD and EERD remains far from being conclusively proven. In addition, there is a general paucity of data supporting a beneficial effect of anti-reflux treatments on symptoms of patients with suspected EERD. Therefore, diagnostic as well as therapeutic management of EERD remains largely empirical. Current guidelines suggest an initial empiric trial of proton pump inhibitors in patients without alarm features, who present also typical GERD symptoms. For those patients who improve with PPIs, GERD is presumed to be the etiology. In patients with refractory reflux, combined impedance/pH monitoring might provide the single best strategy for evaluating reflux symptoms. In this context, as symptoms ascribable to GERD may depend on other causes, investigations that excludes GERD can help to redirect the diagnostic and treatment efforts to other pathological conditions. The present review intends to discuss the current state of knowledge regarding the challenging diagnostic and therapeutic management of patients with suspected EERD, emphasizing the points of strengths and limitations of currently available diagnostic options, and to provide an update on major diagnostic innovations in this area.

Abstract The idiopathic inflammatory myopathies (IIM) are acquired muscle diseases characterized by muscle weakness and inflammation on muscle biopsy. Clinicoserologic classifications do not take muscle histology into account to distinguish the subsets of IIM. Our objective was to determine the pathologic features of each serologic subset of IIM and to correlate muscle biopsy results with the clinicoserologic classification defined by Troyanov et al, and with the final diagnoses. We retrospectively studied a cohort of 178 patients with clinicopathologic features suggestive of IIM with the exclusion of inclusion body myositis. At the end of follow-up, 156 of 178 cases were still categorized as IIM: pure dermatomyositis, n = 44; pure polymyositis, n = 14; overlap myositis, n = 68; necrotizing autoimmune myopathy, n = 8; cancer-associated myositis, n = 18; and unclassified IIM, n = 4. The diagnosis of IIM was ruled out in the 22 remaining cases. Pathologic dermatomyositis was the most frequent histologic picture in all serologic subsets of IIM, with the exception of patients with anti-Ku or anti-SRP autoantibodies, suggesting that it supports the histologic diagnosis of pure dermatomyositis, but also myositis of connective tissue diseases and cancer-associated myositis. Unspecified myositis was the second most frequent histologic pattern. It frequently correlated with overlap myositis, especially with anti-Ku or anti-PM-Scl autoantibodies. Pathologic polymyositis was rare and more frequently correlated with myositis mimickers than true polymyositis. The current study shows that clinicoserologic and pathologic data are complementary and must be taken into account when classifying patients with IIM patients. We propose guidelines for diagnosis according to both clinicoserologic and pathologic classifications, to be used in clinical practice. PMID:23269233

Effect of Lower Anogenital Squamous Terminology Recommendations on the Use of p16 Immunohistochemistry and the Proportion of High-Grade Diagnoses in Cervical Biopsy Specimens.

Thrall, Michael J

2016-04-01

The Lower Anogenital Squamous Terminology (LAST) group has recommended that cervical intraepithelial neoplasia (CIN) terminology be replaced by squamous intraepithelial lesion (SIL) terminology, with p16 immunohistochemistry used to separate lesions formerly diagnosed as CIN grade 2 into high-grade SILs (HSILs) and low-grade SILs. This study investigated the impact of these changes on the frequency of p16 testing and the diagnosis of high-grade lesions. Pathology reports for all cervical biopsy specimens in the 1 year before and after the introduction of LAST recommendations (July 2011 to June 2013) were examined. Before and after the implementation of LAST, 365 (15.4%) of 2,376 cases were diagnosed as high grade (CIN 2/3) vs 486 (17.6%) of 2,761 cases diagnosed as HSILs (P = .0343), and p16 was performed 79 (3.3%) times vs 383 (13.9%) times (P < .0001). Immunohistochemistry for p16 increased dramatically as a result of LAST recommendations, and high-grade diagnoses increased. © American Society for Clinical Pathology, 2016. All rights reserved.

Accumulating evidence suggests that prostatic cancers represent a group of histologically and molecularly heterogeneous diseases with variable clinical courses. In accordance with the increased knowledge of their clinicopathologies and genetics, the World Health Organization (WHO) classification of prostatic cancers has been revised. Additionally, recent data on their comprehensive molecular characterization have increased our understanding of the genomic basis of prostatic cancers and enabled us to classify them into subtypes with distinct molecular pathologies and clinical features. Our increased understanding of the molecular pathologies of prostatic cancers has permitted their evolution from a poorly understood, heterogeneous group of diseases with variable clinical courses to characteristic molecular subtypes that allow the implementation of personalized therapies and better patient management. This review provides perspectives on the new 2016 WHO classification of prostatic cancers as well as recent knowledge of their molecular pathologies. The WHO classification of prostatic cancers will require additional revisions to allow for reliable and clinically meaningful cancer diagnoses as a better understanding of their molecular characteristics is obtained.

On-site pathology services are an integral part of many dermatology and surgical dermatology practices in the United States. Assess the effectiveness and advantages of on-site pathology services. Biopsy data from 7 practices with on-site pathology services were reviewed to determine the diagnostic accuracy of malignancies from all lesional biopsies. Patient preference and convenience were queried and measured with satisfaction surveys. Of note, 1,052/1,379 (76.3%) of biopsies demonstrated a malignancy. Most patients underwent treatment of malignant lesions on a different day than the biopsy. Of the patients who scheduled a return visit for surgery on a later date, 42/246 (17.1%) reported incurring additional costs and 44/249 (17.7%) had a relative/friend who was inconvenienced. On-site pathology services provide efficient, effective, and convenient care for skin cancer patients. Fellowship-trained dermatologic surgeons use on-site pathology services to diagnose and treat clinically relevant nonmelanoma skin cancer.

Diagnosis of gastro esophageal reflux disease (GERD) in children is challenging. 24-h-pH-multichannel-intraluminal-impedance measurement (pH-MII) is the best diagnostic tool to display gastro esophageal reflux whereas esophageal endoscopy indicates mucosal lesions. The aim of this study was to compare esophageal endoscopy results with reflux parameters such as acid exposure time (reflux index RI), bolus exposure time (bolus index BI), baseline impedance level (BIL) detected by pH-MII in children with suspected GERD. Analysis of data from 285 children (38 infants) referred to our hospital with suspected GERD. Division into three 'reflux esophagitis' (RE)-stages depending on the severity of endoscopic and histological findings and comparison with reflux parameters in these stages. Further categorization into four groups based on the pH-MII-results. Children with high-grade esophagitis had a significantly lower BIL; otherwise there was no significant association between elevated reflux parameters and esophagitis. Pathological pH-MII results (RI and BI) were associated with lower BIL in the distal impedance channel. The BIL was significantly lower in infants compared to children >1 year regardless of the RI or BI. The main difference between these groups regarding reflux parameters was a longer BI and a higher number of retrograde bolus movements. Pathologic pH-MII results are not predictive for an erosive esophagitis and vice versa. Therefore, these two procedures cannot replace each other. A lower BIL is associated with esophagitis ≥ LA-grade B and may be caused by longer acid but also by longer bolus exposure and thus may be another useful parameter in GERD monitoring.

Thyroid-related mortality has remained constant despite the increasing incidence of thyroid carcinoma. Most thyroid nodules are benign; therefore, ultrasound and fine needle aspiration (FNA) are integral in cancer screening. We hypothesize that increased nodule size at ultrasound does not predict malignancy and correlation between nodule size at ultrasound and pathologic exam is good. Resected thyroids with preoperative ultrasounds were identified. Nodule size at ultrasound, FNA diagnosis by Bethesda category, size at pathologic examination, and final histologic diagnosis were recorded. Nodule characteristics at ultrasound and FNA diagnoses were correlated with gross characteristics and histologic diagnoses. Nodules for which correlation could not be established were excluded. Of 1003 nodules from 659 patients, 26% were malignant. Nodules <2 cm had the highest malignancy rate (∼30%). Risk was similar (∼20%) for nodules ≥2 cm. Of the 548 subject to FNA, 38% were malignant. Decreasing malignancy rates were observed with increasing size (57% for nodules <1 cm to 20% for nodules >6 cm). At ultrasound size cutoffs of 2, 3, 4, and 5 cm, smaller nodules had higher malignancy rates than larger nodules. Of the 455 not subject to FNA, 11% were malignant. Ultrasound size alone is a poor predictor of malignancy, but a relatively good predictor of final pathologic size (R 2  = 0.748), with less correlation at larger sizes. In nodules subject to FNA, false negative diagnoses were highest (6-8%) in nodules 3-6 cm, mostly due to encapsulated follicular variant of papillary carcinoma. Thyroid nodule size is inversely related to malignancy risk, as larger nodules have lower malignancy rates. However, the relationship of size to malignancy varies by FNA status. All nodules (regardless of FNA status) demonstrate a risk trough at ≥2 cm. Nodules subject to FNA show step-wise decline in malignancy rates by size, demonstrating that size alone should not be

To evaluate retrospectively the comorbidity of mental and addictive disorders in community mental health and substance misuse services in Madrid. The medical records of 400 patients from mental health and substance misuse services in Madrid were evaluated. Records were examined for the last 20 patients from each service unit. Dual pathology was constituted when a current diagnosis of mental and addictive disorders, excluding nicotine addiction, appeared on the patient's records. Prevalence of dual pathology was 34%. There were differences in the prevalence figures for the two kinds of service: 36.78% in substance misuse services, and 28.78% in mental health services. There was an association of dual diagnosis with alcohol or cocaine dependence, but not with opioid dependence. The mental disorders more prevalent in dually diagnosed than in non-dually diagnosed patients were mood disorders, personality disorders, and schizophrenia. There is a high prevalence of dual pathology in those seeking treatment, being higher in substance misuse services than in mental health services, and higher in patients with alcohol or cocaine dependence. These findings could be of help in the planning of care resource policies for these patients.

To test the hypothesis that late-life depression is associated with dementia-related pathology. Older participants (n = 1,965) in 3 longitudinal clinical-pathologic cohort studies who had no cognitive impairment at baseline underwent annual clinical evaluations for a mean of 8.0 years (SD = 5.0). The authors defined depression diagnostically, as major depression during the study period, and psychometrically, as elevated depressive symptoms during the study period, and established their relation to cognitive outcomes (incident dementia, rate of cognitive decline). A total of 657 participants died and underwent a uniform neuropathologic examination. The authors estimated the association of depression with 6 dementia-related markers (tau tangles, beta-amyloid plaques, Lewy bodies, hippocampal sclerosis, gross and microscopic infarcts) in logistic regression models. In the full cohort, 9.4% were diagnosed with major depression and 8.6% had chronically elevated depressive symptoms, both of which were related to adverse cognitive outcomes. In the 657 persons who died and had a neuropathologic examination, higher beta-amyloid plaque burden was associated with higher likelihood of major depression (present in 11.0%; OR = 1.392, 95% CI = 1.088, 1.780) but not with elevated depressive symptoms (present in 11.3%; OR = 0.919, 95% CI = 0.726, 1.165). None of the other pathologic markers was related to either of the depression measures. Neither dementia nor antidepressant medication modified the relation of pathology to depression. The results do not support the hypothesis that major depression is associated with dementia-related pathology. PsycINFO Database Record (c) 2016 APA, all rights reserved.

Objective: To describe an adolescent with pathologic aerophagia, a rare condition caused by excessive and inappropriate swallowing of air and to review its treatment and differential diagnoses. Case description: An 11-year-old mentally impaired blind girl presenting serious behavior problems and severe developmental delay with abdominal distension from the last 8 months. Her past history included a Nissen fundoplication. Abdominal CT and abdominal radiographs showed diffuse gas distension of the small bowel and colon. Hirschsprung's disease was excluded. The distention was minimal at the moment the child awoke and maximal at evening, and persisted after control of constipation. Audible repetitive and frequent movements of air swallowing were observed. The diagnosis of pathologic aerophagia associated to obsessive-compulsive disorder and developmental delay was made, but pharmacological treatment was unsuccessful. The patient was submitted to an endoscopic gastrostomy, permanently opened and elevated relative to the stomach. The distention was resolved, while maintaining oral nutrition. Comments: Pathologic aerophagia is a rare self-limiting condition in normal children exposed to high levels of stress and may be a persisting problem in children with psychiatric or neurologic disease. In this last group, the disease may cause serious complications. Pharmacological and behavioral treatments are ill-defined. Severe cases may demand surgical strategies, mainly decompressive gastrostomy. PMID:26100594

The etiology of iron deficiency (ID) without anemia in young men is unclear, and there are no evidence-based recommendations for the required gastrointestinal (GI) evaluation. The aims of this study were to examine the incidence of significant GI pathology and the development of anemia during the follow-up of young men presenting with ID, but without anemia. All young men (18-30 years) who served in the Israel Defense Forces during the years 2005-2013 and had at least a single laboratory test indicative of ID without anemia were followed until the diagnosis of significant GI pathology or discharge from military service. The study population included 2061 young men (mean age 20.7±1.8). During follow-up of 3150 person years, significant GI pathologies were diagnosed in 39 patients: inflammatory bowel disease in 25 (1.2%), celiac disease in 8 (0.4%), and peptic disease in 4 (0.1%). No cases of GI-related cancer were diagnosed. ID anemia developed during follow-up in 203 (9.8%). Lower baseline hemoglobin levels, lower ferritin levels, and younger age at diagnosis were more common among those who developed anemia. The development of anemia was a predisposing factor for the diagnosis of GI pathology (risk ratio=3.60, 95% confidence interval 1.34-8.32, P=0.012). Significant GI pathology is very uncommon in young men presenting with ID. Overt anemia developed in close to 10% of the study cohort. Therefore, we advise simple GI evaluation (celiac serology, C-reactive protein or fecal calprotectin, and urease breath test) as well as follow-up in this population.

Gastroesophageal Reflux: Regurgitation in the Infant Population.

2018-03-01

Gastroesophageal reflux (GER) is common in infancy and mainly treated through nonpharmacological interventions. Knowing the early warning signs of GER is important for nursing assessment. Untreated GER can become acute when an infant fails to gain weight and has recurrent, forceful vomiting. Further investigation of gastroesophageal reflux disease (GERD) is indicated when failure to gain weight, irritability, swallowing difficulties, regurgitation, and respiratory complications occur and should trigger referral to pediatric specialists. This article will share information about uncomplicated GER, GERD, and symptoms of these diagnoses, common screening tests, and treatment options. Copyright © 2017 Elsevier Inc. All rights reserved.

The goal of this study is to create an objective pathological diagnostic system for blood and lymphatic vessel invasion (BLI). 1450 surgically resected colorectal cancer specimens from eight hospitals were reviewed. Our first step was to compare the current practice of pathology assessment among eight hospitals. Then, H&E stained slides with or without histochemical/immunohistochemical staining were assessed by eight pathologists and concordance of BLI diagnosis was checked. In addition, histological findings associated with BLI having good concordance were reviewed. Based on these results, framework for developing diagnostic criterion was developed, using the Delphi method. The new criterion was evaluated using 40 colorectal cancer specimens. Frequency of BLI diagnoses, number of blocks obtained and stained for assessment of BLI varied among eight hospitals. Concordance was low for BLI diagnosis and was not any better when histochemical/immunohistochemical staining was provided. All histological findings associated with BLI from H&E staining were poor in agreement. However, observation of elastica-stained internal elastic membrane covering more than half of the circumference surrounding the tumour cluster as well as the presence of D2-40-stained endothelial cells covering more than half of the circumference surrounding the tumour cluster showed high concordance. Based on this observation, we developed a framework for pathological diagnostic criterion, using the Delphi method. This criterion was found to be useful in improving concordance of BLI diagnosis. A framework for pathological diagnostic criterion was developed by reviewing concordance and using the Delphi method. The criterion developed may serve as the basis for creating a standardised procedure for pathological diagnosis.

The pathology of acute appendicitis.

Carr, N J

2000-02-01

Although acute appendicitis is frequent, it is subject to common misconceptions. Furthermore, there is little good evidence to support some of our beliefs. This report reviews the role of the anatomic pathologist in diagnosis when acute appendicitis is suspected clinically and discusses what is known of its pathology. The conclusions that can be legitimately drawn from the literature are emphasized. A classification is proposed that incorporates intraluminal inflammation, acute mucosal inflammation, acute mucosal and submucosal inflammation, suppurative (phlegmonous) appendicitis, gangrenous appendicitis, and periappendicitis, and the significance of each of these diagnoses is discussed. The etiology and pathogenesis of acute appendicitis is reviewed. Contrary to popular belief, the best evidence indicates that obstruction is unlikely to be the primary cause, at least in the majority of cases. Ancillary techniques in the diagnosis of appendicitis, including laparoscopy and peritoneal aspiration cytology, are discussed.

This pathology PILOT study aims to define the role and feasibility of centralized pathology review in a cohort of 75 patients from different centers in the United States and Europe using digital slide scanning. The pathologic material from 75 patients who had been diagnosed with mycosis fungoides/Sézary syndrome and were clinically staged as IIb or above was retrieved from 11 participating centers. Each pathology reviewer was provided with the pathologic diagnosis (by the referring pathologist), and the following list of histopathologic criteria (presence or absence) from the initial report: epidermotropism, folliculotropism (FT), large cell transformation, syringotropism, and granulomas. Patients with advance stage were selected for this study as this is a population where there is significant variability in the diagnosis of pathologic prognostic and predictive biomarkers. The slides were digitally scanned with an Aperio scanner and consensus review of cases occurred when major or minor discrepancies between the referral diagnosis and central pathology review occurred. Among the 75 cases, 70 (93.3%) had a final consensus diagnosis between the 3 central review pathologists. The overall agreement between the consensus review and the referring pathologist was 60%. The overall agreement was also higher between the reviewers and consensus review, compared with the referring pathologist and consensus. 65.3% of cases had some type of discrepancy (major or minor) between the outside and consensus review. Major discrepancies were seen in 34 of 73 cases (46.6%; 73 cases indicated a yes or no response). Minor discrepancies were seen in 32 of 75 (42.7%) of cases. Most of the major discrepancies were accounted by a difference in interpretation in the presence or absence of large cell transformation or FT. Most minor discrepancies were explained by a different interpretation in the expression of CD30. We found digital slide scanning to be a beneficial, reliable, and practical

General practitioners (GPs) are key members of the health care profession who are required to have a considerable breadth of knowledge to manage and treat patients effectively in the community. Their skills and experience varies depending on the medical school they attended and their foundation training and specialist GP training schemes. Exposure to ear, nose, and throat (ENT)-specific pathology is often insufficient due to the lack of formal otolaryngology rotations, minimal relevant teaching opportunities, and inconsistencies in curricula, despite ENT-related pathology presentations being one of the commonest consultations in primary care. We undertook a learning needs assessment among Watford general practice vocational training scheme trainees to assess whether they lacked confidence in managing typical ENT pathology, as well as to ascertain whether they felt a formal and focused ENT teaching session would be beneficial to them. The results suggested they were interested in such a session, and therefore we organized a formal program on the assessment and management of acute and common ENT pathologies with a postteaching questionnaire to evaluate participant confidence in these domains. The results showed an improvement in participant knowledge and confidence regarding the assessment and management of ENT pathologies following the teaching session intervention. In addition, most attendees were overall very satisfied with the session. This study highlights the need for teaching specifically tailored to the learning needs of general practice vocational training scheme trainees, particularly in niche specialties, in order to prepare them adequately for clinical practice in the community setting.

Borderline risk lesions such as flat epithelial atypia (FEA) are increasingly being diagnosed on biopsy. The need for surgery is being debated. In this study, we determined the frequency of histological upgrade following a diagnosis of FEA on biopsy and evaluated potential predictive factors. Retrospective review was done of 194 women who underwent biopsy of indeterminate lesions (total 195 lesions) that were diagnosed as FEA. The review covered a 10-year period. Cases where malignancy was also present together with FEA within the same biopsy cores were excluded. Lesions diagnosed as FEA on biopsy were mostly asymptomatic and presented as microcalcifications on mammogram. Flat epithelial atypia was the only abnormality detected in one-third of cases, was associated with a benign or another borderline lesion in another third and was associated with atypical ductal hyperplasia (ADH) in another third. Six patients (3.1%) were later found to have ductal carcinoma-in-situ (DCIS) at surgery. The presence of ADH in the biopsy was the only predictor of histological upgrade to malignancy (P = 0.04, OR 11.24, 95% CI 1.10 - 115.10), and was present in 5 of the 6 patients. Surgery was advised in the last patient because of radiology-pathology discordance. Thirty-six lesions (18.5%) were not excised and no interval progression or malignancy was found on follow up. Histological upgrade to malignancy was uncommon in lesions found on biopsy to be FEA. Non-operative management of biopsy-proven FEA can be considered in the absence of ADH and radiology-pathology discordance. Copyright © 2017 Elsevier Ltd. All rights reserved.

Eighty pathology cases were sent independently to each of two telepathology servers. Cases were submitted from the Department of Pathology at the University of Kerman in Iran (40 cases) and from the Institute of Pathology in Berlin, Germany (40 cases). The telepathology servers were located in Berlin (the UICC server) and Basel in Switzerland (the iPATH server). A scoring system was developed to quantify the differences between the diagnoses of the referring pathologist and the remote expert. Preparation of the cases, as well as the submission of images, took considerably longer from Kerman than from Berlin; this was independent of the server system. The Kerman delay was mainly associated with a slower transmission rate and longer image preparation. The diagnostic gap between referrers' and experts' diagnoses was greater with the iPATH system, but not significantly so. The experts' response time was considerably shorter for the iPATH system. The results showed that telepathology is feasible for requesting pathologists working in a developing country or in an industrialized country. The key factor in the quality of the service is the work of the experts: they should be selected according to their diagnostic expertise, and their commitment to the provision of telepathology services is critical.

The current literature indicates that a considerable number of patients in ovarian carcinoma clinical trials have histopathological diagnoses in conflict with inclusion criteria. It has been suggested that specialised pathology review prior to randomisation should become the standard procedure in study protocols. We hypothesised that our new, internet-based high-throughput infrastructure would be capable of providing specialised pathology review within 10 working days (w.d.). Patients scheduled for the AGO OVAR17 ovarian carcinoma chemotherapy trial were registered for expert pathologic case review using a new internet-based central pathology review platform prior to randomisation. All original slides were requested from local pathologists. Slides were scanned and uploaded to a secured internet server. A network of experienced gynaecological pathologists was connected to the server through a custom-designed software platform. If deemed necessary by the expert pathologists, immunohistochemistry was available through a collaborating pathology lab. A total of 880 patients with an original diagnosis of ovarian epithelial carcinoma were registered for expert pathology review from October 2011 to July 2013. For case review, five gynaecopathologists from Austria, Switzerland and Germany were available online. Median number of w.d. required to complete the whole process from patient registration to transmission of final review diagnoses was 4 (range 2-31) (w.d.), and in 848 out of 880 (97.5%) cases, it amounted to ⩽10 w.d. In 2.5% (n=22) of cases, a major diagnostic discrepancy of potential clinical relevance was found leading to exclusion from the chemotherapy trial. Our results show that the use of a new internet-based infrastructure makes timely specialised case review, prior to patient randomisation feasible within ⩽10 w.d. Our new approach helped to protect against overtreatment with chemotherapy of patients with ovarian borderline tumours and inadequate treatment

In Landspitali University Hospital, magnetic resonance imaging is used non-selectively in addition to mammogram and ultrasound in the preoperative assessment of breast cancer patients. The aim of this study was to assess invasive tumor size on imaging, compare with pathological size and evaluate the impact of magnetic resonance imaging on the type of surgery performed. All women with invasive breast cancer, diagnosed in Iceland, between 2007 and 2009 were reviewed retrospectively. In all, 438 of 641 (68%) patients diagnosed had preoperative magnetic resonance imaging. Twelve patients treated with neoadjuvant chemotherapy were excluded and 65 patients with multifocal or contralateral disease were assessed separately. Correlations between microscopic and radiologic tumor sizes were relatively weak. All imaging methods were inaccurate especially for large tumors, resulting in an overall underestimation of tumor size for these tumors. Magnetic resonance imaging under- and overestimated pathological tumor size by more than 10 mm in 16/348 (4.6%) and 26/348 patients (7.5%), respectively. In 19 patients (73%), overestimation of size was seen exclusively on magnetic resonance imaging. For tumors under- or overestimated by magnetic resonance imaging, the mastectomy rates were 56% and 65%, respectively, compared to an overall mastectomy rate of 43%. Of 51 patients diagnosed with multifocal disease on pathology, 19 (37%) were diagnosed by mammogram or ultrasound and 40 (78%) by magnetic resonance imaging resulting in a total detection rate of 84% (43 patients). Fourteen (3%) patients were diagnosed preoperatively with contralateral disease. Of those tumors, all were detected on magnetic resonance imaging but seven (50%) were also detected on mammogram or ultrasound or both. Our results suggest that routine use of magnetic resonance imaging may result in both under- and overestimation of tumor size and increase mastectomy rates in a small proportion of patients.

To explore the relationship between pathological features and clinical manifestations in children with nephropathy under 6 years old. Renal biopsy by rapid percutaneous puncturation was performed on 313 children under 6 who were all diagnosed clinically as kidney diseases of 14 different kinds. The specimens were divided into 3 parts for microscope, electron microscope and immuno fluorescence examination respectively and processed by HE, PAS, PASM, and Masson staining. Immunofluorescence was used to detect the deposition of IgG, IgM, IgA, C3, C4, C1q, and Fb in the renal tissues. Additional examinations were done to detect HBs-Ag, HBeAg and HBcAg deposition in some cases with positive serum HBs-Ag. Altogether 290 of the specimens (290/313, 92.65%) were examined by electron microscope. All the renal biopsy performances were successful. The clinical manifestations comprised of persistent haematuria (32.92%, 103/313), idiopathic nephritic syndrome (26.1%, 82/313), acute nephritic syndrome (20.14%, 63/313), Henoch Schonlein purpura nephritis (8.32%, 26/313), HBV-nephritis (4.79%, 15/313), and isolated proteinuria (2.56%, 8/313). The main pathological patterns of glomerular disease were identified as mesangial proliferation (51.75%, 162/313), IgM nephropathy (8.31%,26/313), minor and minimal change (7.99%, 25/313), IgA nephropathy (7.35%, 23/313), endocapillary proliferative glomerulonephritis (5.11%, 16/313), focus segmental glomerulosclerosis (4.47%, 14/313), thin basement membrane nephropathy (4.47%, 14/313), and membrane nephropathy (4.47%, 14/313). Alport syndrome, congenital nephrotic syndrome, and thin basement membrane nephropathy can be diagnosed by electron microscope, white IgA nephropathy, IgM nephropathy and C1q nephropathy by immunopathology. Similar clinical manifestations may differ in the pathology and the clinical features of one pathological diagnosis may vary greatly. Renal biopsy is of great help to the diagnosis, treatment and the prognosis

Prior work has shown that digital images and microscopic slides can be interpreted with comparable diagnostic accuracy. Although accuracy has been well-validated, the interpretative time for digital images has scarcely been studied and concerns about efficiency remain a major barrier to adoption. We investigated the efficiency of digital pathology when compared with glass slide interpretation in the diagnosis of surgical pathology biopsy and resection specimens. Slides were pulled from 510 surgical pathology cases from 5 organ systems (gastrointestinal, gynecologic, liver, bladder, and brain). Original diagnoses were independently confirmed by 2 validating pathologists. Diagnostic slides were scanned using the Philips IntelliSite Pathology Solution. Each case was assessed independently on digital and optical by 3 reading pathologists, with a ≥6 week washout period between modalities. Reading pathologists recorded assessment times for each modality; digital times included time to load the case. Diagnostic accuracy was determined based on whether a rendered diagnosis differed significantly from the original diagnosis. Statistical analysis was performed to assess for differences in interpretative times across modalities. All 3 reading pathologists showed comparable diagnostic accuracy across optical and digital modalities (mean major discordance rates with original diagnosis: 4.8% vs. 4.4%, respectively). Mean assessment times ranged from 1.2 to 9.1 seconds slower on digital versus optical. The slowest reader showed a significant learning effect during the course of the study so that digital assessment times decreased over time and were comparable with optical times by the end of the series. Organ site and specimen type did not significantly influence differences in interpretative times. In summary, digital image reading times compare favorably relative to glass slides across a variety of organ systems and specimen types. Mean increase in assessment time is 4

The purpose of this study was to investigate differences in family functioning between families with clinical subjects in paediatric age and families taken from the Italian population. To this aim we used the Family Adaptability and Cohesion Evaluation Scale (FACES). Participants were children diagnosed with a psychopathology, recruited into the psychiatry department in a Paediatric Hospital of Rome. A total of 106 families participated in the study. The non-pathological sample is composed by 2,543 parents in different age periods of the life-cycle. Results showed significant differences in family functioning between pathological and non-pathological samples. Specifically, families from the pathological sample (particularly the ones who experienced eating disorders) were more frequently located in extreme or mid-range regions of Olson's circumplex model (p < .001). These findings suggest some considerations that can be useful in therapeutic works with families in a clinical setting. Critical aspects and clinical applications are discussed.

Breast cancer is the most common among women in our country, and its treatment is based on prognostic factors to categorize patients into different risk groups. In this study, the clinical and pathological features that play a role as a prognostic factor in a representative population with breast cancer in México are described. A descriptive analysis of the clinical and pathological features of women diagnosed with breast cancer, in a period from June 2005 to May 2014; registered in a database and calculated by simple frequencies. A total of 4,411 patients were included, the average age at diagnosis was 53 years, 19.7% were diagnosed by mammography screening program and 80.3% derived from any signs or symptoms. Regarding the stages at diagnosis, 6.8% were carcinoma in situ, 36% at early stages (I and IIA), 45% locally advanced (IIB to IIIC), 7.7% metastatic and 3.9% unclassifiable. A 79% were ductal histology, lobular 7.8% and the rest, other types. Of ductal carcinomas, 9.1% were grade I, 54.1% grade II, and 34.6% grade III. Regarding the biological subtypes, 65.7% were luminal, 10.9% luminal Her positive, 8.7% pure Her 2 positive and 14.6% triple negative. In the present study, we described the clinical and pathologic features of a group of Mexican women with breast cancer that might reflect a national landscape, and represent the prognostic factors to determine groups of risk and treatment decisions.

To assess the overall exposure after a single dose of esomeprazole in children with gastroesophageal reflux disease (GERD). Oral esomeprazole administered as an intact capsule with 30 - 180 mL of water, or as an opened capsule mixed with as much as 1 tablespoon of applesauce followed by 30 - 180 mL of water. In this randomized, open-label study of children aged 1 - 11 years with endoscopically proven GERD, patients weighing 8 - < 20 kg were randomized to a single 5- or 10-mg oral dose of esomeprazole, and patients weighing >= 20 kg were randomized to a single 10- or 20-mg oral dose of esomeprazole. Esomeprazole exposure (AUC(0-∞)), AUC from zero to last measurable concentration (AUC(0-t)), maximum plasma concentration (C(max)), time to C(max) (t(max)), terminal-phase half-life, apparent oral clearance, and apparent volume of distribution were determined. 28 patients were randomized to receive esomeprazole: 14 patients weighing 8 to < 20 kg received esomeprazole 5 mg (n = 7) or 10 mg (n = 7), and 14 patients weighing ≥20 kg received esomeprazole 10 mg (n = 6) or 20 mg (n = 8). Children weighing 8 - < 20 kg had a 1.8-fold higher exposure with the 10-mg vs. 5-mg dose (AUC(0-∞), 1.32 vs. 0.73 μmol·h/L, respectively); children weighing ≥ 20 kg had a 4.4-fold higher exposure with the 20-mg vs. 10-mg dose (AUC(0-∞), 3.06 vs. 0.69 μmol·h/L). C(max) was 2.2-fold higher for the 10-mg vs. 5-mg dose (8 to < 20 kg) and 2.4-fold higher for the 20-mg vs.10-mg dose (>= 20 kg). The pharmacokinetics of single-dose esomeprazole were dose-dependent in children weighing >= 20 kg but not in children weighing 8 to < 20 kg.

Posterior ankle impingement is a clinical diagnosis which can be seen following a traumatic hyper-plantar flexion event and may lead to painful symptoms in athletes such as female dancers ('en pointe'), football players, javelin throwers and gymnasts. Symptoms of posterior ankle impingement are due to failure to accommodate the reduced interval between the posterosuperior aspect of the talus and tibial plafond during plantar flexion, and can be due to osseous or soft tissue lesions. There are multiple causes of posterior ankle impingement. Most commonly, the structural correlates of impingement relate to post-traumatic synovitis and intra-articular fibrous bands-scar tissue, capsular scarring, or bony prominences. The aims of this pictorial review article is to describe different types of posterior ankle impingement due to traumatic and non-traumatic osseous and soft tissue pathology in athletes, to describe diagnostic imaging strategies of these pathologies, and illustrate their imaging features, including relevant differential diagnoses.

Pathology in Greece.

PubMed

Sakellariou, S; Patsouris, E

Pathology is the field of medicine that studies diseases. Ancient Greece hosted some of the earliest societies that laid the structural foundations of pathology. Initially, knowledge was based on observations but later on the key elements of pathology were established based on the dissection of animals and the autopsy of human cadavers. Christianized Greece under Ottoman rule (1453-1821) was not conducive to the development of pathology. After liberation, however, a series of events took place that paved the way for the establishment and further development of the specialty. The appointment in 1849 of two Professors of Pathology at the Medical School of Athens for didactical purposes proved to be the most important step in fostering the field of pathology in modern Greece. Presently in Greece there are seven university departments and 74 pathology laboratories in public hospitals, employing 415 specialized pathologists and 90 residents. The First Department of Pathology at the Medical School of Athens University is the oldest (1849) and largest in Greece, encompassing most pathology subspecialties.

pathologist. Coincidental overlaps of the area of subspecialty surgical pathology expertise with organ-related incoming cases did not influence decisions by the telepathologists to either defer those cases or to agree or disagree with the referring pathologist's provisional diagnoses. Conclusions: Subspecialty surgical pathologists effectively served as general surgical pathologists on a telepathology-based surgical pathology QA service. Concurrence rates with incoming surgical pathology report diagnoses, and case deferral rates, varied significantly among the 10 on-service telepathologists. We found no evidence that the higher deferral rates correlated with improving the accuracy or quality of the surgical pathology reports. PMID:25057432

In gastro-oesophageal reflux disease (GERD), heartburn responds well to acid suppression, but regurgitation is a common cause of incomplete treatment response. To assess the prevalence and burden of persistent, frequent regurgitation in primary care patients with GERD treated with acid suppression. We analysed observational data from 134 sites across six European countries in patients diagnosed with GERD. Within 3 months of the index visit, symptoms were assessed using the Reflux Disease Questionnaire, and their impact on sleep and work productivity with the Quality of Life in Reflux and Dyspepsia questionnaire and the Work Productivity and Activity Impairment Questionnaire, respectively. Patients provided information on concomitant over-the-counter (OTC) GERD medication use. Persistent, frequent (3-7 days/week) regurgitation was reported by 13.2% (153/1156) of GERD patients with no heartburn on acid suppression; the prevalence was very similar for patients with up to 2 days/week of ongoing mild heartburn. Among patients without heartburn, sleep disturbance of any type was reported by 50.7-60.1% with persistent, frequent regurgitation, compared with 38.1-51.1% and 14.4-19.2% of those with less frequent or no regurgitation respectively. Persistent, frequent regurgitation was associated with increased use of OTC medication and more hours of work missed, whether mild, infrequent heartburn was present or not. Frequent regurgitation, which persisted in 12-13% of patients with no or infrequent, mild heartburn on acid suppression, negatively affected sleep and work productivity, and increased use of OTC medication. Persistent, frequent regurgitation is problematic for primary care patients with GERD. © 2013 Blackwell Publishing Ltd.

Numerous definitions of adverse pathology at radical prostatectomy (RP) have been proposed and implemented for both research and clinical care, and there is tremendous variation in the specific criteria used to define adverse pathology in these settings. Given the current landscape in which magnetic resonance imaging criteria and biomarker cutoffs are validated for disparate adverse pathology definitions, we sought to identify which of these is most closely tied to biochemical recurrence (BCR) after RP. A total of 2,837 patients who underwent RP at a single institution for localized prostate cancer (PCa) were included. We evaluated the following existing definitions of adverse pathology at RP: (1) Gleason score ≥7, (2) primary Gleason pattern ≥4, (3) Gleason score ≥7 or pathologic stage T3-4, (4) pathologic stage T3-4, (5) primary Gleason pattern ≥4 or pathologic stage T3-4. The primary outcome measure was BCR. Multiple statistical techniques were used to assess BCR prediction. Of the 5 definitions assessed, 1 (primary Gleason pattern ≥4 or pathologic stage T3-4, 540 patients [19% of cohort]) consistently outperformed the other definitions across all statistical measures. Additionally, a total of only 13 (6.6%) and 34 (10.3%) men with very-low-risk and low-risk cancer per National Comprehensive Cancer Network guideline, respectively, met this definition of adverse pathology at the time of RP. Varying definitions of adverse pathology differ in their prognostic performance. The criteria defined by either primary Gleason pattern ≥4 or pT3-4 disease appears to most accurately predict BCR in this subset of patients with lower risk PCa at the time of diagnosis. Additionally, men with very-low-risk or low-risk PCa per National Comprehensive Cancer Network guidelines are relatively unlikely to have adverse pathology at the time of surgical resection. These data may help inform the use of imaging and molecular markers as well as the intensity of surveillance in

In this work, the spatial localization of leucocytes, bacteria, and erythrocytes in the crystal pattern of a dried droplet of cerebrospinal fluid (CSF) is established. Characteristic lines are detected and identified in the Raman spectrum of the CSF that point to the presence of pathologic cells therein and can be used in a timely way to diagnose meningitis, the spectroscopic sample preparation procedure being simple enough. A dry CSF sample retains its characteristic spectral features for no less than three days, which is important for its safe keeping and transportation, and also for the computer processing of its spectra.

Diagnosing clostridial enteric disease in poultry.

Cooper, Kerry K; Songer, J Glenn; Uzal, Francisco A

2013-05-01

The world's poultry industry has grown into a multibillion-dollar business, the success of which hinges on healthy intestinal tracts, which result in effective feed conversion. Enteric disease in poultry can have devastating economic effects on producers, due to high mortality rates and poor feed efficiency. Clostridia are considered to be among the most important agents of enteric disease in poultry. Diagnosis of enteric diseases produced by clostridia is usually challenging, mainly because many clostridial species can be normal inhabitants of the gut, making it difficult to determine their role in virulence. The most common clostridial enteric disease in poultry is necrotic enteritis, caused by Clostridium perfringens, which typically occurs in broiler chickens but has also been diagnosed in various avian species including turkeys, waterfowl, and ostriches. Diagnosis is based on clinical and pathological findings. Negative culture and toxin detection results may be used to rule out this disease, but isolation of C. perfringens and/or detection of its alpha toxin are of little value to confirm the disease because both are often found in the intestine of healthy birds. Ulcerative enteritis, caused by Clostridium colinum, is the other major clostridial enteric disease of poultry. Diagnosis of ulcerative enteritis is by documentation of typical pathological findings, coupled with isolation of C. colinum from the intestine of affected birds. Other clostridial enteric diseases include infections produced by Clostridium difficile, Clostridium fallax, and Clostridium baratii.

The objective of the present study was to estimate the influence of gastroesophageal reflux disease (GERD) on the pH values in the pharynx and nose. It included 87 patients at the age varying from 18 to 81 years admitted to the Irkutsk-based Railway Clinical Hospital and allocated to four groups. Group 1 was comprised of 25 patients presenting with gastroesophageal reflux disease and chronic rhinosinusitis (CRS), group 2 consisted of 29 patients with CRS in the absence of GERD, group 3 included 22 patients with nasal septum deformations (NSD) and GERD, group 4 included 11 patients with NSD and motor rhinitis without GERD. The control group was formed from 10 volunteers. pH was measured by the contact method with the use ofEkokhim indicator paper. Gastroesophageal reflux disease was diagnosed following the recommendations of the Montreal consensus. It was shown that pH values in the pharynx of the patients with compromised nasal breathing of any origin in combination with GERD were lower than in the absence of GERD and in the healthy volunteers. The study groups did not differ in terms of pH values in the nasal cavity. It is concluded that pH values 4 or lower may serve as the criterion for pharyngo-laryngeal reflux (PLR) concomitant with HERD while pH 5 occurs more frequently in the patients with compromised nasal breathing of any etiology, regardless of the presence or absence of GERD.Disordered nasal breathing of any genesis in the patients presenting with gastroesophageal reflux disease was associated with the feeling of the lump in the throat, congestion of the respiratory tract and the nose, pain in the ears, cardialgia, and irregular heartbeat. It isrecommended to use pH measurements as a criterion for diagnostics of pharyngo-laryngeal reflux in the patients presenting with gastroesophageal reflux disease.

Peroral endoscopic myotomy (POEM) does not include any antireflux procedure, resulting in a certain risk of iatrogenic gastroesophageal reflux disease (GERD). The aim of the present study was to evaluate the incidence of iatrogenic GERD after POEM and identify preoperative, perioperative and postoperative factors associated with GERD. All patients treated at a single center who had a complete GERD evaluation after POEM were included in the study. Demographics, preoperative and follow-up data, results of functional studies and procedural data were collected and analyzed. A total of 103 patients (mean age 46.6 years, 47 males) were included. Postoperative altered esophageal acid exposure was attested in 52 patients (50.5%). A total of 19 patients (18.4%) had heartburn and 21 had esophagitis (20.4%). Overall, a clinically relevant GERD (altered esophageal acid exposure, associated with heartburn and/or esophagitis) was diagnosed in 30 patients (29.1%). Correlation between the severity of esophageal acid exposure with heartburn and esophagitis after POEM was found. Patients with heartburn had a lower postoperative 4-second integrated relaxation pressure compared to patients without symptoms (7.6 ± 3.8 mmHg vs 10.01 ± 4.4 mmHg, p<0.05). No correlations were identified with patient sex, age, postoperative body mass index, esophageal shape (sigmoid vs non sigmoid), lower esophageal sphincter pressure, length of myotomy, previous therapies and type of achalasia at high-resolution manometry. Preoperative, perioperative or postoperative factors minimally correlated with GERD after POEM. Clinically relevant GERD was identified in less than one-third of patients, but all patients were well controlled with medical therapy. © 2015 The Authors Digestive Endoscopy © 2015 Japan Gastroenterological Endoscopy Society.

Summary Pathology consensus review for clinical trials and disease classification has historically been performed by manual light microscopy with sequential section review by study pathologists, or multi-headed microscope review. Limitations of this approach include high intra- and inter-reader variability, costs, and delays for slide mailing and consensus reviews. To improve this, the Nephrotic Syndrome Study Network (NEPTUNE) is systematically applying digital pathology review in a multicenter study using renal biopsy whole slide imaging (WSI) for observation-based data collection. Study pathology materials are acquired, scanned, uploaded, and stored in a web-based information system that is accessed through a web-browser interface. Quality control includes metadata and image quality review. Initially, digital slides are annotated, with each glomerulus identified, given a unique number, and maintained in all levels until the glomerulus disappears or sections end. The software allows viewing and annotation of multiple slide sections concurrently. Analysis utilizes “descriptors” for patterns of injury, rather than diagnoses, in renal parenchymal compartments. This multidimensional representation via WSI, allows more accurate glomerular counting and identification of all lesions in each glomerulus, with data available in a searchable database. The use of WSI brings about efficiency critical to pathology review in a clinical trial setting, including independent review by multiple pathologists, improved intraobserver and interobserver reproducibility, efficiencies and risk reduction in slide circulation and mailing, centralized management of data integrity and slide images for current or future studies, and web-based consensus meetings. The overall effect is improved incorporation of pathology review in a budget neutral approach. PMID:23393107

The group of non-small cell lung carcinomas includes tumors that are variable at the clinical, histopathological and molecular levels. Advances in the understanding of molecular pathology of lung adenocarcinomas in particular has led to changes in their histopathological classification and treatment. Patients diagnosed with lung adenocarcinoma harboring specific mutations benefit from the administration of specific targeted therapy. Therefore, pathologists closely involved in the diagnostics of lung tumors significantly contribute to the diagnostic-therapeutical algorithm. Analysis of EGFR gene mutations in lung adenocarcinomas is already routinely performed and the presence of activating mutations in EGFR is the main indication for the administration of tyrosinkinase inhibitors. Besides EGFR mutations, EML4-ALK rearrangement is also being analysed and there is potential in analysing BRAF mutations as well. The aim of this review is to summarize the role of the most relevant molecules that also serve as the therapeutic target for practicing pathologists.

Aims The goal of this study is to create an objective pathological diagnostic system for blood and lymphatic vessel invasion (BLI). Methods 1450 surgically resected colorectal cancer specimens from eight hospitals were reviewed. Our first step was to compare the current practice of pathology assessment among eight hospitals. Then, H&E stained slides with or without histochemical/immunohistochemical staining were assessed by eight pathologists and concordance of BLI diagnosis was checked. In addition, histological findings associated with BLI having good concordance were reviewed. Based on these results, framework for developing diagnostic criterion was developed, using the Delphi method. The new criterion was evaluated using 40 colorectal cancer specimens. Results Frequency of BLI diagnoses, number of blocks obtained and stained for assessment of BLI varied among eight hospitals. Concordance was low for BLI diagnosis and was not any better when histochemical/immunohistochemical staining was provided. All histological findings associated with BLI from H&E staining were poor in agreement. However, observation of elastica-stained internal elastic membrane covering more than half of the circumference surrounding the tumour cluster as well as the presence of D2-40-stained endothelial cells covering more than half of the circumference surrounding the tumour cluster showed high concordance. Based on this observation, we developed a framework for pathological diagnostic criterion, using the Delphi method. This criterion was found to be useful in improving concordance of BLI diagnosis. Conclusions A framework for pathological diagnostic criterion was developed by reviewing concordance and using the Delphi method. The criterion developed may serve as the basis for creating a standardised procedure for pathological diagnosis. PMID:23592799

The right atrium: gateway to the heart--anatomic and pathologic imaging findings.

2015-01-01

Knowledge of right atrial anatomic and pathologic imaging findings and associated clinical symptoms is important to avoid false-positive diagnoses and missed findings. Complete evaluation of the heart often requires a multimodality approach that includes radiography, echocardiography, computed tomography (CT), magnetic resonance (MR) imaging, and invasive angiography. In general, CT provides the highest spatial resolution of these modalities at the cost of radiation exposure to the patient. Echocardiography and MR imaging offer complementary and detailed information for functional evaluation without added radiation exposure. The advantages and disadvantages of each modality for the evaluation of right atrial anatomic structure, size, and pathologic findings are discussed. Cardiac MR imaging is the reference standard for evaluation of right atrial size and volume but often is too time consuming and resource intensive to perform in routine clinical practice. Therefore, established reference ranges for two-dimensional transthoracic echocardiography are often used. Right atrial pathologic findings can be broadly categorized into (a) congenital anomalies (cor triatriatum dexter, Ebstein anomaly, and aneurysm), (b) disorders of volume (tricuspid regurgitation, pathologic mimics such as a pseudoaneurysm, and atrial septal defect), (c) disorders of pressure (tricuspid stenosis, restrictive cardiomyopathy, and constrictive pericarditis), and (d) masses (pseudomasses, thrombus, lipomatous hypertrophy of the interatrial septum, lipoma, myxoma, sarcoma, and metastatic disease). Familiarity with each pathologic entity and its treatment options is essential to ensure that appropriate imaging modalities are selected. Online supplemental material is available for this article.

The Surveillance, Epidemiology and End Results (SEER) program of the National Cancer Institute collects data on cancer diagnoses, treatment and survival for approximately 30% of the United States (U.S.) population. To reflect advances in research and oncology practice, approaches to cancer control are evolving from simply enumerating the development of cancers by organ sites in populations to include monitoring of cancer occurrence by histopathologic and molecular subtype, as defined by driver mutations and other alterations. SEER is an important population-based resource for understanding the implications of pathology diagnoses across demographic groups, geographic regions, and time, and provides unique insights into the practice of oncology in the U.S that are not attainable from other sources. It provides incidence, survival and mortality data for histopathologic cancer subtypes, and data by molecular subtyping is expanding. The program is developing systems to capture additional biomarker data, results from special populations, and expand bio-specimen banking to enable cutting edge cancer research that can improve oncology practice. Pathology has always been central and critical to the effectiveness of SEER, and strengthening this relationship in this modern era of cancer diagnosis could be mutually beneficial. Achieving this goal requires close interactions between pathologists and the SEER program. This review provides a brief overview of SEER, focuses on facets relevant to pathology practice and research, and highlights the opportunities and challenges for pathologists to benefit from and enhance the value of SEER data.

Insulin and leptin have proliferative and anti-apoptotic effects. Ghrelin promotes gastric emptying and secretion of growth hormone and inhibits inflammation. We assessed whether diabetes mellitus and serum levels of insulin, leptin, and ghrelin are associated with gastroesophageal reflux disease (GERD) and Barrett's esophagus. We conducted a case-control study in 822 men undergoing colorectal cancer screening who were recruited to also undergo upper endoscopy. We identified 70 with Barrett's esophagus; 80 additional men with Barrett's esophagus were recruited shortly after their clinical diagnoses. Serum levels of insulin, leptin, and ghrelin were assayed in all 104 fasting men with Barrett's esophagus without diabetes and 271 without diabetes or Barrett's esophagus. Logistic regression was used to estimate the effects of diabetes and levels of insulin, leptin, and ghrelin on GERD and Barrett's esophagus. Among men with GERD, diabetes was inversely associated with Barrett's esophagus (adjusted odds ratio [OR] = 0.383; 95% confidence interval [CI]: 0.179-0.821). Among nondiabetics, hyperinsulinemia was positively associated with Barrett's esophagus, but the association was attenuated by adjustment for leptin and ghrelin. Leptin was positively associated with Barrett's esophagus, adjusting for obesity, GERD, and levels of insulin and ghrelin (OR for 3(rd) vs 1(st) tertile = 3.25; 95% CI: 1.29-8.17); this association was stronger in men with GERD (P = .01 for OR heterogeneity). Ghrelin was positively associated with Barrett's esophagus (OR for an increment of 400 pg/mL = 1.39; 95% CI: 1.09-1.76), but inversely associated with GERD (OR for 3(rd) vs 1(st) tertile = 0.364; 95% CI: 0.195-0.680). Based on a case-control study, leptin was associated with Barrett's esophagus, particularly in men with GERD. Serum insulin level was associated with Barrett's esophagus, but might be mediated by leptin. Serum ghrelin was inversely associated with GERD, as hypothesized, but

Background/Aims: In this study, we aimed to determine the prevalence of gastroesophageal reflux disease (GERD) in the general population of the capital city of Riyadh and to assess its association with other factors including age, smoking, body mass index (BMI), asthma, as well as the presence of other co-morbid diseases. Materials and Methods: We used the Gastroesophageal Reflux Disease Questionnaire (GerdQ) for diagnosing GERD, based on a GerdQ score of 8 or more. Riyadh was divided into four quadrants, and from each area, a single shopping mall was chosen randomly to conduct our surveys. Data collected included age, sex, history of smoking, history of asthma or any other medical condition, dietary habits, monthly household income, history and frequency of heartburn, epigastric pain, regurgitation of food, nausea, sleep disturbance from heartburn, the use of common over-the-counter antacids for the control of their symptoms, and their height and weight. Results: Over a 4-week period from the 19 December 2012 to 17 January 2013, a total of 1265 individuals were included in the survey. The mean age was 29.97 ± 11.58 years. Females formed 67.81% of the respondents and 62.73% had one or more episodes of heartburn per week. Based on a cutoff GERDQ score of 8, the prevalence of GERD in the surveyed population was 45.4%. GERD was more prevalent in older individuals (mean age 31.9 vs. 30.0 years, P < 0.001) and in those with a higher BMI (27.29 vs. 26.31 kg/m2, P = 0.02). There was no difference between males (45.43%) and females (45.13%) (P = 0.92); there was a trend of a higher prevalence in smokers (51.63% vs. 44.41%), but it did not reach statistical significance (P = 0.09). Conclusion: Symptoms suggestive of GERD as determined by the translated GerdQ are prevalent among this study population. PMID:25038211

Morbidly obese patients are affected by gastroesophageal reflux disease (GERD) and hiatal hernia (HH) more frequently than lean patients. Because of conflicting results, the indication to sleeve gastrectomy (SG) in patients with GERD is still debated. To evaluate the incidence of GERD on the basis of clinical, endoscopic, and histologic data in patients undergoing SG. University hospital, Rome, Italy. From July 2007 to January 2010, 162 patients underwent primary SG. Preoperatively all patients underwent visual analogue scale (VAS) evaluation of GERD symptoms, proton pump inhibitors (PPIs) consumption recording, and esophagogastroduodenoscopy (EGD). Stomach resection started 6 cm from pylorus on a 48Fr bougie. Staple line was reinforced by an oversewing suture. A postoperative clinical control with VAS evaluation, PPI consumption, and EGD was proposed to all patients. Three patients were excluded because of the occurrence of major postoperative complications. A total of 110 patients accepted to take part in the study (follow-up rate: 69.1%). At a mean 58 months of follow-up, incidence of GERD symptoms, VAS mean score, and PPI intake significantly increased compared with preoperative values (68.1% versus 33.6%: P<.0001; 3 versus 1.8: P = .018; 57.2% versus 19.1%: P<.0001) At EGD, an upward migration of the "Z" line and a biliary-like esophageal reflux was found in 73.6% and 74.5% of cases, respectively. A significant increase in the incidence and in the severity of erosive esophagitis (EE) was evidenced, whereas nondysplastic Barrett's esophagus (BE) was newly diagnosed in 19 patients (17.2%). No significant correlations were found between GERD symptoms and endoscopic findings. In the present series the incidence of EE and of BE in SG patients was considerably higher than that reported in the current literature, and it was not related to GERD symptoms. Endoscopic surveillance after SG should be advocated irrespective of the presence of GERD symptoms. Copyright �

Significant progress in the knowledge of carcinogenesis and natural history of colorectal carcinoma (CRC), especially in polyp-cancer sequention and time for transition, are important prerequisites for a new approach to diagnosis. Surgical resection is the mainstay therapy for colorectal cancer, and pathologic assessment of the resected specimen provides data for assessment of outcome and rationale for adjuvant therapy. A pathology report includes TNM stage, tumor type, histologic grade, status of resection margins, and vascular invasion. The purpose of this paper was to highlight the pathological features and their correlations with postoperative evolution and prognosis of this cancer. Data was collected using the database system of the Emergency County Hospital of Craiova, Romania. A total of 302 patients from January 2003 to December 2005 were included. The average survival for the entire group was 44.35 ± 28.94 months, and the D'Agostino-Pearson test for batch distribution showed abnormal distribution with two peaks, separated by a group of five patients who survived between 37 and 8 months. Fifty-one (38.05%) patients presented a median survival of 73.54 ± 10.47 months. Factors that contribute to a favorable prognosis in CRC are vegetant gross tumors and papillary microscopic forms, G1 and G2 degree of differentiation and disease diagnosed in stages I and II.

To describe an adolescent with pathologic aerophagia, a rare condition caused by excessive and inappropriate swallowing of air and to review its treatment and differential diagnoses. An 11 year-old mentally impaired blind girl presenting serious behavior problems and severe developmental delay with abdominal distension from the last 8 months. Her past history included a Nissen fundoplication. Abdominal CT and abdominal radiographs showed diffuse gas distension of the small bowel and colon. Hirschsprung's disease was excluded. The distention was minimal at the moment the child awoke and maximal at evening, and persisted after control of constipation. Audible repetitive and frequent movements of air swallowing were observed. The diagnosis of pathologic aerophagia associated to obsessive compulsive disorder and developmental delay was made, but pharmacological treatment was unsuccessful. The patient was submitted to an endoscopic gastrostomy, permanently opened and elevated relative to the stomach. The distention was resolved, while maintaining oral nutrition Pathologic aerophagia is a rare self-limiting condition in normal children exposed to high levels of stress and may be a persisting problem in children with psychiatric or neurologic disease. In this last group, the disease may cause serious complications. Pharmacological and behavioral treatments are ill-defined. Severe cases may demand surgical strategies, mainly decompressive gastrostomy. Copyright © 2015 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda. All rights reserved.

A case review by specialist diagnostic pathologists as part of a Gynecologic Oncology Multi-disciplinary Tumor group has the potential to influence the management of patients with cancer. The primary aim of this study was to determine the frequency of diagnostic discrepancies between the initial (nonspecialist) and final pathological diagnoses in cases referred to the Gynecologic Oncology Tumor Conference (TC) in Western Australia and the impact of such revised diagnosis on clinical management. A secondary aim was to assess the evolving workload encountered by the TC during a 5-year interval. The records of the weekly TC for the 2 calendar years 2008 and 2013 were examined, and histological and cytological specimens that had been initially assessed by "outside" (nonspecialist) pathology departments, and subsequently reviewed by specialist pathologists, were assessed. The initial and final diagnoses were compared, and where the pathological findings were amended upon review, it was determined whether the change affected clinical management. Diagnostic discrepancies that resulted in a change in patient management were classified as major, whereas discrepancies that did not affect patient management were classified as minor. A total of 481 outside cases were included among 2387 cases presented for histological review at the TC during the 2 years. For outside cases alone, the incidence of major diagnostic discrepancies was 3.4% in 2008, 5.5% in 2013 (no significant difference, P = 0.3787), and 4.6% for the 2 years combined. A recommendation for surgery was the most common change in clinical management as a result of major discrepancy. The minor discrepancy rate was 4.4% of outside cases for both years combined. Pathological discrepancies (major and minor) of the uterine corpus and cervix were most frequent, followed by those of the vulva and ovary. There was a 48.4% increase in total case discussions at the TC during the interval period with a significant rise in

The acid pocket: a target for treatment in reflux disease?

The nadir esophageal pH of reflux observed during pH monitoring in the postprandial period is often more acidic than the concomitant intragastric pH. This paradox prompted the discovery of the "acid pocket", an area of unbuffered gastric acid that accumulates in the proximal stomach after meals and serves as the reservoir for acid reflux in healthy individuals and gastroesophageal reflux disease (GERD) patients. However, there are differentiating features between these populations in the size and position of the acid pocket, with GERD patients predisposed to upward migration of the proximal margin onto the esophageal mucosa, particularly when supine. This upward migration of acid, sometimes referred to as an "acid film", likely contributes to mucosal pathology in the region of the squamocolumnar junction. Furthermore, movement of the acid pocket itself to a supradiaphragmatic location with hiatus hernia increases the propensity for acid reflux by all conventional mechanisms. Consequently, the acid pocket is an attractive target for GERD therapy. It may be targeted in a global way with proton pump inhibitors that attenuate acid pocket development, or with alginate/antacid combinations that colocalize with the acid pocket and displace it distally, thereby demonstrating the potential for selective targeting of the acid pocket in GERD.

Erosion of the palmar (flexor) aspect of the navicular bone is difficult to diagnose with conventional imaging techniques. To review the clinical, magnetic resonance (MR) and pathological features of deep erosions of the palmar aspect of the navicular bone. Cases of deep erosions of the palmar aspect of the navicular bone, diagnosed by standing low field MR imaging, were selected. Clinical details, results of diagnostic procedures, MR features and pathological findings were reviewed. Deep erosions of the palmar aspect of the navicular bone were diagnosed in 16 mature horses, 6 of which were bilaterally lame. Sudden onset of lameness was recorded in 63%. Radiography prior to MR imaging showed equivocal changes in 7 horses. The MR features consisted of focal areas of intermediate or high signal intensity on T1-, T2*- and T2-weighted images and STIR images affecting the dorsal aspect of the deep digital flexor tendon, the fibrocartilage of the palmar aspect, subchondral compact bone and medulla of the navicular bone. On follow-up, 7/16 horses (44%) had been subjected to euthanasia and only one was being worked at its previous level. Erosions of the palmar aspect of the navicular bone were confirmed post mortem in 2 horses. Histologically, the lesions were characterised by localised degeneration of fibrocartilage with underlying focal osteonecrosis and fibroplasia. The adjacent deep digital flexor tendon showed fibril formation and fibrocartilaginous metaplasia. Deep erosions of the palmar aspect of the navicular bone are more easily diagnosed by standing low field MR imaging than by conventional radiography. The lesions involve degeneration of the palmar fibrocartilage with underlying osteonecrosis and fibroplasia affecting the subchondral compact bone and medulla, and carry a poor prognosis for return to performance. Diagnosis of shallow erosive lesions of the palmar fibrocartilage may allow therapeutic intervention earlier in the disease process, thereby preventing

Background Community data suggest frequent co-occurrence between schizophrenia/schizoaffective disorder and problem gambling. However, gambling behaviors in large samples of patients with schizophrenia/schizoaffective disorder have not been systematically examined to date. Methods A sample of outpatient subjects (n=337) diagnosed with schizophrenia/schizoaffective disorder or schizoaffective disorder and treated in either a VA hospital or a local state mental health center was interviewed in order to examine the prevalence estimates and clinical correlates of problem and pathological gambling. Multinomial logistic regression models investigated clinically relevant measures in recreational or problem/pathological gamblers, as compared to non-gamblers. Results Sixty-five participants (19%) met criteria for past-year problem/pathological gambling, with 10% meeting criteria for pathological gambling. Significant correlates of problem and pathological gambling from multivariable models included greater alcohol use severity (p=0.007), higher depression scores (p=0.04), and more outpatient mental health care utilization (p=0.03). Participants with problem/pathological gambling were more likely than recreational gamblers to gamble for excitement, gamble more frequently and heavily, and report either sports or card gambling as favorite. Conclusions A substantial proportion of individuals in treatment for psychotic disorders report past-year gambling problems. Patients with co-occurring alcohol use problems and depression may be at particularly high risk. These findings suggest the need for improved prevention and treatment efforts related to problem/pathological gambling in individuals with psychotic disorders. PMID:19538900

Aerophagia is a disorder caused by abnormal accumulation of air in the gastrointestinal tract as a result of repetitive and frequent inflow of air through the mouth. For the diagnosis of this condition, it is difficult to objectively measure the air swallowing. However, multichannel intraluminal impedance monitoring facilitates the differential diagnosis between normal air swallowing and pathologic aerophagia, and can aid in the determination of the frequency and amount of air swallowed. In this report, in addition to a literature review, we describe a case of 36-year-old man with abdominal distension who was diagnosed with aerophagia using esophageal impedance monitoring and was treated with clonazepam.

Pathological jealousy evokes emotions, thoughts, and behaviors that cause damage to social and interpersonal relationships. On the other hand, pathological love is the uncontrollable behavior of caring for a partner that results in neglecting the needs of the self. The aim of the present research was to assess the similarities and differences between the two psychopathologies of love. To this end, thirty-two individuals with pathological jealousy and 33 individuals with pathological love were compared on demographics, aspects of romantic relationship (jealousy, satisfaction, love style), psychiatric co-morbidities, personality and psychological characteristics (e.g., impulsivity). In a univariate analysis individuals with pathological jealousy were more likely to be in a current relationship and reported greater satisfaction. The avoidant attachment and the ludus love style were associated with pathological jealousy whereas the secure attachment and agape love style was associated with pathological love. Almost three-quarters (72.3%) of the sample met criteria for a current psychiatric disorder, however no differences emerged between the pathological jealousy and pathological love groups. In a binary logistic regression, relationship status and impairments in parenting significantly differentiated the groups. While both pathological jealousy and pathological love share similarities, they also present with unique differences, which may have important treatment implications. Copyright © 2017 Elsevier B.V.

New developments in digital pathology: from telepathology to virtual pathology laboratory.

2004-01-01

To analyse the present status and future development of computerized diagnostic pathology in terms of work-flow integrative telepathology and virtual laboratory. Telepathology has left its childhood. The technical development of telepathology is mature, in contrast to that of virtual pathology. Two kinds of virtual pathology laboratories are emerging: a) those with distributed pathologists and distributed (>=1) laboratories associated to individual biopsy stations/surgical theatres, and b) distributed pathologists working in a centralized laboratory. Both are under technical development. Telepathology can be used for e-learning and e-training in pathology, as exemplarily demonstrated on Digital Lung Pathology Pathology (www.pathology-online.org). A virtual pathology institution (mode a) accepts a complete case with the patient's history, clinical findings, and (pre-selected) images for first diagnosis. The diagnostic responsibility is that of a conventional institution. The internet serves as platform for information transfer, and an open server such as the iPATH (http://telepath.patho.unibas.ch) for coordination and performance of the diagnostic procedure. The size of images has to be limited, and usual different magnifications have to be used. A group of pathologists is "on duty", or selects one member for a predefined duty period. The diagnostic statement of the pathologist(s) on duty is retransmitted to the sender with full responsibility. First experiences of a virtual pathology institution group working with the iPATH server (Dr. L. Banach, Dr. G. Haroske, Dr. I. Hurwitz, Dr. K. Kayser, Dr. K.D. Kunze, Dr. M. Oberholzer,) working with a small hospital of the Salomon islands are promising. A centralized virtual pathology institution (mode b) depends upon the digitalisation of a complete slide, and the transfer of large sized images to different pathologists working in one institution. The technical performance of complete slide digitalisation is still under

Influence of proton pump inhibitors on gastritis diagnosis and pathologic gastric changes

AIM: To investigate the influence of proton pump inhibitors (PPIs) exposure on the diagnosis of Helicobacter pylori (H. pylori) gastritis and intestinal metaplasia. METHODS: Chronic PPI use is associated with masking of H. pylori infection. Patients with H. pylori infection are predisposed to gastric and duodenal ulcers, and long-term infection with this organism has been associated with gastric mucosal atrophy and serious long-term complications, such as gastric lymphoma and adenocarcinoma. Three hundred patients diagnosed with gastritis between January 2008 and April 2010 were included in our study. The computerized medical database of these patients was reviewed retrospectively in order to assess whether the type of gastritis diagnosed (H. pylori vs non-H. pylori gastritis) is influenced by PPI exposure. H. pylori density was graded as low, if corresponding to mild density following the Updated Sydney System, or high, if corresponding to moderate or severe densities in the Updated Sydney System. RESULTS: Patients were equally distributed between males and females with a median age at the time of diagnosis of 50 years old (range: 20-87). The histological types of gastritis were classified as H. pylori gastritis (n = 156, 52%) and non-H. pylori gastritis (n = 144, 48%). All patients with non-H. pylori gastritis had inactive chronic gastritis. Patients with no previous PPI exposure were more likely to be diagnosed with H. pylori gastritis than those with previous PPI exposure (71% vs 34.2%, P < 0.001). Intestinal metaplasia was more likely to be detected in the latter patients (1.4% vs 6.5%, P = 0.023). Multivariate analysis has also demonstrated that in the presence of previous PPI exposure (OR = 0.217, 95%CI: 0.123-0.385), GERD (OR = 0.317, 95%CI: 0.132-0.763, P = 0.01), alcohol intake (OR = 0.396, 95%CI: 0.195-0.804, P = 0.01), the detection of H. pylori was less likely. Chronic use of PPIs may mask H. pylori infections promoting the diagnosis of non-H. pylori

Pathological processes observed in the stomatognathic systems of mammalian species are a useful source of information about the habits, evolution and general health of such animals. Studies of pathological conditions on teeth are common in humans and other primates, but rare in wild animals in general and marine mammals in particular. For cetaceans, previous studies provided scanty records of dental anomalies in a few species. This is the first broad and systematic inventory of dental pathology in dolphins. Specimens stored at scientific collections from the southern coast of Brazil were visually inspected under a stereoscopic microscope using a dental explorer. Diagnosis of lesions and anomalies followed literature descriptions. Abnormalities such as caries-like lesions, mineralized calculus deposits, dental erosion, enamel anomalies (hypoplasia and exogenous pigmentation), root resorption, germination and other shape anomalies, were diagnosed in the delphinids Sotalia guianensis, Delphinus capensis, Stenella frontalis, Stenella coeruleoalba, Lagenodelphis hosei, Pseudorca crassidens, Orcinus orca, Steno bredanensis and Tursiops truncatus. Endogenous causes may be related to the occurrence of certain conditions, but the aetiology of caries-like lesions and calculus accumulation is still unknown for cetaceans. The diagnosis of alveolar anomalies and other bone lesions in specimens with dental pathology lead us to believe these lesions modify the integrity of the periodontal ligament and bony tissues, adding to the burden of morbidity of affected animals.

Varieties of Pathological Self-mutilation.

PubMed

Favazza, A R; Rosenthal, R J

1990-01-01

Pathological self-mutilation appears as a non-specific symptom as well as a specific syndrome. Since psychotic persons may commit horrifying acts, such as enucleation of an eye or amputation of a body part, identification of high risk patients is crucial. Stereotypical self-mutilation, such as head banging and biting off of fingertips, is associated with mental retardation and with the syndromes of Lesch-Nyhan, deLange, and Tourette. This type of self-mutilation is the focus of biological research or endorphins and on dopamine receptors. Skin cutting and burning, the most common type of self-mutilation, is often associated with personality disorders, post-traumatic stress disorder, and multiple personality disorder. When cutting and burning become established as responses to disturbing psychological symptoms on environmental events, a specific Axis I impulse disorder known as Repetitive Self Mutilation may be diagnosed. Patients with this newly identified syndrome may alternate their direct acts of self-mutilation with eating disorders and episodic alcoholism.

Gastroesophageal reflux disease: an Asian perspective.

PubMed

Wu, Justin C Y

2008-12-01

The prevalence of gastroesophageal reflux disease (GERD) ranges from 2.5% to 7.1% in most population-based studies in Asia. There is evidence that GERD and its complications are rising, coinciding with a decline in Helicobacter pylori (H. pylori) infection. Asian GERD patients share similar risk factors and pathophysiological mechanisms with their Western counterparts. Possible causes for the lower prevalence of GERD include less obesity and hiatus hernia, a lesser degree of esophageal dysmotility, a high prevalence of virulent strains of H. pylori, and low awareness. Owing to the lack of precise translation for 'heartburn' in most Asian languages, reflux symptoms are often overlooked or misinterpreted as dyspepsia or chest pain. Furthermore, a symptom-based diagnosis with a therapeutic trial of the proton pump inhibitor (PPI) may be hampered by the high prevalence of H. pylori-related disease. The risk stratification for prompt endoscopy, use of a locally-validated, diagnostic symptom questionnaire, and response to H. pylori'test and treat' help improve the accuracy of the PPI test for diagnoses. PPI remain the gold standard treatment, and 'on-demand' PPI have been shown to be a cost-effective, long-term treatment. The clinical course of GERD is benign in most patients in Asia. The risk of progression from non-erosive reflux disease to erosive esophagitis is low, and treatment response to a conventional dose of PPI is generally higher. Although H. pylori eradication may lead to more resilient GERD in a subset of patients, the benefits of H. pylori eradication outweigh the risks, especially in Asian populations with a high incidence of gastric cancer.

Proton pump inhibitors (PPI) are among the most commonly prescribed medicines and their overuse is widespread in both primary and secondary care. Inappropriate prescription is of particular concern among elderly patients, who have often multiple comorbidities and need many drugs. We evaluate the appropriateness of drugs for peptic ulcer or gastro-esophageal reflux disease (GERD) in a sample of elderly patients (65 years old or older) at admission and discharge in 38 internal medicine wards between January 2008 and December 2008, according to the presence of specific conditions or gastro-toxic drug combinations. Among 1155 patients eligible for the analysis, 466 (40.3%) were treated with drugs for GERD or peptic ulcer were at hospital admission and 647 (56.0%) at discharge; 62.4% of patients receiving a drug for peptic ulcer or GERD at admission and 63.2% at discharge were inappropriately treated. Among these, the number of other drugs prescribed was associated with greater use of drugs for peptic ulcer or GERD, even after adjustment for age, sex and number of diagnoses at admission (OR 95% CI=1.26 (1.18-1.34), p=.0001) or discharge (OR 95% CI=1.11 (1.05-1.18), p=0.0003). Prevalence of inappropriate prescription of drugs for peptic ulcer or GERD remained almost the same at admission and discharge. Inappropriate use of these drugs is related to the concomitant use of other drugs. Careful assessment of clinical conditions and stricter adherence to evidence-based guidelines are essential for a rational and cost-effective use of drugs for peptic ulcer or GERD.

2014-01-01

Objective To update the findings of the 2005 systematic review of population-based studies assessing the epidemiology of gastro-oesophageal reflux disease (GERD). Design PubMed and Embase were screened for new references using the original search strings. Studies were required to be population-based, to include ≥200 individuals, to have response rates ≥50% and recall periods <12 months. GERD was defined as heartburn and/or regurgitation on at least 1 day a week, or according to the Montreal definition, or diagnosed by a clinician. Temporal and geographic trends in disease prevalence were examined using a Poisson regression model. Results 16 studies of GERD epidemiology published since the original review were found to be suitable for inclusion (15 reporting prevalence and one reporting incidence), and were added to the 13 prevalence and two incidence studies found previously. The range of GERD prevalence estimates was 18.1%–27.8% in North America, 8.8%–25.9% in Europe, 2.5%–7.8% in East Asia, 8.7%–33.1% in the Middle East, 11.6% in Australia and 23.0% in South America. Incidence per 1000 person-years was approximately 5 in the overall UK and US populations, and 0.84 in paediatric patients aged 1– 17 years in the UK. Evidence suggests an increase in GERD prevalence since 1995 (p<0.0001), particularly in North America and East Asia. Conclusions GERD is prevalent worldwide, and disease burden may be increasing. Prevalence estimates show considerable geographic variation, but only East Asia shows estimates consistently lower than 10%. PMID:23853213

Ultrasonography (US) cannot demonstrate all the etiologies of biliary tract dilatation in patients with jaundice. Thus, we evaluated the etiologic yield of endosonography (EUS) for suspected obstructive jaundice when no definite pathology was found on US. Additionally, we sought to identify the predictors of the most common etiologies. We performed a retrospective review of 123 consecutive patients who had undergone EUS for suspected obstructive jaundice when no definite pathology was identified on US. The most common diagnoses included no pathological obstruction (n = 43), pancreatobiliary malignancy (n = 41), and choledocholithiasis (n = 28). Pancreatobiliary malignancy was associated with common bile duct (CBD) dilatation, and fever and elevated alanine aminotransferase were predictors of choledocholithiasis (p < 0.05). The accuracy of EUS was 95.9% (118/123) for overall cause of suspected obstructive jaundice, 100% (40/40) for no pathological finding, 100% (23/23) for ampullary cancer, 100% (13/13) for pancreatic cancer, 75% (3/4) for CBD cancer, and 92.9% (26/28) for choledocholithiasis, respectively. Besides the two patients with focal chronic pancreatitis misdiagnosed as with pancreatic cancer, EUS missed the lesions in one CBD cancer patient and two patients with choledocholithiasis. The overall accuracy of EUS in ascertaining pancreatobiliary malignancy and choledocholithiasis was comparable (97.6%, 40/41 vs. 92.9%, 26/28; p > 0.05). Marked CBD dilatation (≥12 mm) should remind us of the high risk of malignancy, and the presence of CBD dilatation and fever is suggestive of choledocholithiasis. Negative EUS findings cannot assure any pathological obstruction in patients with clinically suspected obstructive jaundice. Copyright © 2013. Published by Elsevier B.V.

Alginate-based formulations are frequently used as add-on proton pump inhibitor (PPI) therapy to help control of heartburn and regurgitation. There are limited data regarding the mechanisms and effects of alginate-based formulations. We aimed to evaluate the effects of the sodium alginate intake and its likely temporal relations on intraesophageal reflux events by MII-pH in patients with and without hiatal hernia (HH). Fifty GERD patients (18 with HH, 32 without HH) with heartburn or regurgitation once a week or more common were included. After combined multichannel intraluminal impedance and pH-metry (MII-pH) had been performed, all patients were asked to eat the same standard meal (double cheeseburger, 1 banana, 100 g regular yoghurt, and 200 mL water with total energy value of 744 kcal: 37.6% of carbohydrates, 21.2% of proteins, and 41.2% of lipids) during two consecutive days. On separate random two consecutive days, all patients took 10 mL of sodium alginate (GA; Gaviscon Advance; Reckitt Benckiser Healthcare, Hull, UK) or 10 mL of water, 30 minutes after the refluxogenic meal. After eating refluxogenic meal, patients were examined ½ hour for basal conditions, 1 hour in upright, and 1 hour in supine positions. Alginate significantly decreased acid reflux after intake at the first hour in comparison to water in patients with HH (6.1 vs. 13.7, P = 0.004) and without HH (3.5 vs. 5.5, P = 0.001). Weakly acid reflux were increased at the first hour in patients with HH (3.4 vs. 1.3, P = 0.019) and without HH (1.7 vs. 5, P = 0.02) compared to water. There was no distinctive effect of alginate on the height of proximal migration of reflux events in patients with HH and without HH. Alginate decreases acid reflux events within a limited time period, especially at the first hour both in patients with and without HH. Alginate has no effect on the height of reflux events along the esophagus both in patients with and without HH. © The Authors 2017. Published by Oxford

Current diagnostic tests for gastroesophageal reflux disease (GERD) do not consistently measure chronicity of reflux. Mucosal impedance (MI) is a minimally invasive measurement to assess esophageal conductivity changes due to GERD. We aimed to investigate MI pattern in patients with symptoms of extraesophageal reflux (EER) in a prospective longitudinal cohort study. Patients with potential symptoms of EER undergoing esophagogastroduodenoscopy (EGD) with wireless pH monitoring were studied. Participants included those with erosive esophagitis (E+), normal EGD/abnormal pH (E-/pH+), and normal EGD/normal pH (E-/pH-). MI was measured from the site of injury in patients with E+, as well as at 2, 5, and 10 cm above the squamocolumnar junction (SCJ) in all participants. Forty-one patients with symptoms of EER were studied. MI measurements at 2 cm above the SCJ were significantly (P = 0.04) different among the three groups, with MI lowest for E+ and greatest for E-/pH- patients. Although not statistically significant, there is a graded increase in median (interquartile range) MI axially along the esophagus at 5 cm (P = 0.20) and at 10 cm (P = 0.27) above the SCJ, with those with reflux (E+ and E-/pH+) having a lower MI than those without. Patients with symptoms of EER and evidence of acid reflux have an MI lower than those without at 2 cm above the SCJ, with a trend at 5 cm and 10 cm as well. MI may be a tool to assess presence of GERD in patients presenting with EER symptoms. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

The failure to consider travel-related diagnoses, the lack of diagnostic capacity for specialized laboratory testing, and the declining number of autopsies may affect the diagnosis and management of travel-related infections. Pre- and post-mortem pathology can help determine causes of illness and death in international travelers. We conducted a retrospective review of biopsy and autopsy specimens sent to the Infectious Diseases Pathology Branch laboratory (IDPBL) at the Centers for Disease Control and Prevention (CDC) for diagnostic testing from 1995 through 2015. Cases were included if the specimen submitted for diagnosis was from a traveler with prior international travel during the disease incubation period and the cause of illness or death was unknown at the time of specimen submission. Twenty-one travelers, six (29%) with biopsy specimens and 15 (71%) with autopsy specimens, met the inclusion criteria. Among the 15 travelers who underwent autopsies, the most common diagnoses were protozoal infections (7 travelers; 47%), including five malaria cases, followed by viral infections (6 travelers; 40%). Biopsy or autopsy specimens can assist in diagnosing infectious diseases in travelers, especially from pathogens not endemic in the U.S. CDC's IDPBL provides a useful resource for clinicians considering infectious diseases in returned travelers.

Equine maxillary cheek teeth apical infections are a significant disorder because of frequent spread of infection to the supporting bones. The accuracy of computed tomographic imaging (CT) of this disorder has not been fully assessed. To compare the radiographic and CT findings in horses diagnosed with maxillary cheek teeth apical infections with pathological findings in the extracted teeth to assess the accuracy of these imaging techniques. Observational clinical study. Thirty-two maxillary cheek teeth (in 29 horses) diagnosed with apical infections by clinical, radiographic and principally by CT examinations, were extracted orally. The extracted teeth were subjected to further CT, gross pathological and histological examinations. Four normal teeth extracted from a cadaver served as controls. Pulpar and apical changes highly indicative of maxillary cheek teeth apical infection were present in all 32 teeth on CT, but in just 17/32 teeth (53%) radiographically. Gross pulpar/apical abnormalities and histological pulpar/periapical changes were present in 31/32 (97%) extracted teeth. On CT, one tooth contained small gas pockets in the apical aspect of one pulp and adjacent periodontal space, however no pathological changes were found following its extraction. The study is descriptive and is confined to a small number of cases. This study showed a 97% agreement between CT diagnosis of maxillary cheek teeth apical infection and the presence of pathological changes in the extracted teeth, confirming the diagnostic accuracy of CT compared with radiography for this disorder. © 2017 EVJ Ltd.

Childhood Maltreatment as Predictor of Pathological Personality Traits Using PSY-5 in an Adult Psychiatric Sample.

PubMed

Choi, Ji Young; Park, Soo Hyun

2018-02-01

Extant literature indicates that childhood maltreatment is significantly associated with personality disorders. With the recent call for a more dimensional approach to understanding personality and pathological personality traits, the aim of the present study was to examine whether the experience of childhood maltreatment is associated with pathological personality traits as measured by the Personality Psychopathology Five (PSY-5). We analyzed data from 557 adult psychiatric patients with diverse psychiatric diagnoses, including mood disorders, schizophrenia spectrum disorders, and anxiety disorders. Hierarchical multiple regression analyses were conducted to determine the degree to which childhood maltreatment explained the five trait dimensions after controlling for demographic variables, presence of psychotic symptoms, and degree of depressive symptoms. Childhood maltreatment significantly predicted all of the five trait dimensions of the PSY-5. This suggests that childhood maltreatment may negatively affect the development of an adaptive adjustment system, thereby potentially contributing to the emergence of pathological personality traits.

Evaluation of gastroesophageal reflux before and after sleeve gastrectomy using symptom scoring, scintigraphy, and endoscopy.

The effect of laparoscopic sleeve gastrectomy (SG) on gastroesophageal reflux disease (GERD) has been a controversial issue. There have been limited studies on this aspect and most of the published studies are retrospective. Therefore, a prospective study was designed to objectively assess the problem. The objective of this study was to assess the impact of SG on symptoms of gastroesophageal reflux using questionnaire, endoscopy, and radionuclide scintigraphy. Thirty-two patients undergoing laparoscopic sleeve gastrectomy were assessed for gastroesophageal reflux using Carlsson Dent Questionnaire and GERD questionnaire before and after surgery at three monthly intervals. They were also subjected to upper GI endoscopy (UGIE) and radionuclide scintigraphy both pre- and postoperatively. Mean preoperative weight and body mass index were 126.5 kg and 47.8 kg/m2, respectively. Mean percent excess weight loss at 12 months was 64.3 ± 18.4. Both the Carlsson Dent Score (CDS) and Severity Score (SS) exhibited a decline from 2.88 to 1.63 (p<0.05) and 2.28 to 1.06 (p<0.05), respectively after 12 months. Radionuclide scintigraphy revealed a significant rise of GERD from 6.25% to 78.1% in the postoperative period (p<0.001). UGIE showed a rise in incidence of esophagitis from 18.8% to 25%; however, there was improvement in all patients except one in terms of reduction of severity of esophagitis. Presence of GERD may not be considered as a contra-indication for sleeve gastrectomy. There is improvement of GERD as assessed by symptom questionnaires, as well as improvement in grade of esophagitis. The new onset GERD detected on scintigraphy may not be pathologic as there is a decrease in total acid production postsurgery; however, it still remains an important issue and needs long-term follow-up.

The Diagnostic Dilemma of Pathological Appearance and Performance Enhancing Drug Use

PubMed Central

Hildebrandt, Tom; Lai, Justine K.; Langenbucher, James W.; Schneider, Melanie; Yehuda, Rachel; Pfaff, Donald W.

2010-01-01

Appearance and performance enhancing drug (APED) use includes the use of a range of pharmacologically distinct substances and concurrent investment in outward appearance or achievement, dietary control, and frequent exercise. A number of existing reviews and conceptual papers have defined pathological forms of APED use within the APED class of anabolic-androgenic steroids (AASs) and using the framework of AAS dependence. We review published data on APED use including human studies of AAS users and identified three defining phenomenological features associated with increased health risk and pathology. These features included (1) polypharmacy or the concurrent use of several pharmacologically distinct substances used to change outward appearance or increase likelihood of personal achievement; (2) significant body image disturbance; (3) rigid practices and preoccupations with diet and exercise. Investigations into the latent structure of APED use suggest these features cluster together in a homogenous group of APED users who have the highest health risk and most psychopathology. These features are discussed in the context of AAS dependence and problems with defining classic tolerance-withdrawal symptoms among APED users. Suggestions for a resolution and outline for future research needed to determine the best system for identifying and diagnosing pathological APED use are discussed. PMID:21115306

Updates of pathologic myopia.

Complications from pathologic myopia are a major cause of visual impairment and blindness, especially in east Asia. The eyes with pathologic myopia may develop loss of the best-corrected vision due to various pathologies in the macula, peripheral retina and the optic nerve. Despite its importance, the definition of pathologic myopia has been inconsistent. The refractive error or axial length alone often does not adequately reflect the 'pathologic myopia'. Posterior staphyloma, which is a hallmark lesion of pathologic myopia, can occur also in non-highly myopic eyes. Recently a revised classification system for myopic maculopathy has been proposed to standardize the definition among epidemiological studies. In this META-PM (meta analyses of pathologic myopia) study classification, pathologic myopia was defined as the eyes having chorioretinal atrophy equal to or more severe than diffuse atrophy. In addition, the advent of new imaging technologies such as optical coherence tomography (OCT) and three dimensional magnetic resonance imaging (3D MRI) has enabled the detailed observation of various pathologies specific to pathologic myopia. New therapeutic approaches including intravitreal injections of anti-vascular endothelial growth factor agents and the advance of vitreoretinal surgeries have greatly improved the prognosis of patients with pathologic myopia. The purpose of this review article is to provide an update on topics related to the field of pathologic myopia, and to outline the remaining issues which need to be solved in the future.

A method for diagnosing diseases having retinal manifestations including retinal pathologies includes the steps of providing a CBIR system including an archive of stored digital retinal photography images and diagnosed patient data corresponding to the retinal photography images, the stored images each indexed in a CBIR database using a plurality of feature vectors, the feature vectors corresponding to distinct descriptive characteristics of the stored images. A query image of the retina of a patient is obtained. Using image processing, regions or structures in the query image are identified. The regions or structures are then described using the plurality of feature vectors. At least one relevant stored image from the archive based on similarity to the regions or structures is retrieved, and an eye disease or a disease having retinal manifestations in the patient is diagnosed based on the diagnosed patient data associated with the relevant stored image(s).

To elucidate the association between gastric acid reflux and respiratory diseases by studying the histological changes of the lower airway in rats with chronic acid reflux esophagitis. An experimental rat model of chronic acid reflux esophagitis was surgically created. The lower airways of these rats were histologically observed for more than 50 weeks. Although there were no histological changes which induced gastric acid reflux at 10 weeks after surgery, thickening of the basal laminae and the proliferation of the collagenous fibers were observed in the alveolar epithelium at 20 weeks after surgery. At 50 weeks after surgery, the collagenous fibers obliterated the pulmonary alveoli and bronchial lumen. These findings observed in the GERD rats are similar to the pathological findings of human pulmonary fibrosis. In this study, we reported pathological changes in the lower airways of GERD rat models observed for more than 50 weeks. These results suggest that gastric acid reflux may be one of the pathogenic or exacerbating factors of pulmonary fibrosis. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The aim of this study was to investigate the follow-up results and characteristics of oval circumscribed lesions with fast initial enhancement on preoperative magnetic resonance imaging (MRI) in patients with newly diagnosed breast cancer.Preoperative data from consecutive patients newly diagnosed with breast cancer between 2010 and 2013 were retrospectively reviewed. Only MRI reports containing, "oval shape, circumscribed margin, and fast initial enhancement," were extracted and analyzed. Follow-up results and clinical and pathological findings were evaluated.A total of 430 oval circumscribed lesions with fast initial enhancement were included. Forty-eight lesions were pathologically confirmed at initial workup and 382 were followed up. Among the 48 lesions, 14 were found to have additional malignancy and 34 were benign. Among the 382 followed-up lesions, only 1 was subsequently confirmed to be malignant. There were no evident changes in any of the remaining lesions during follow-up. The overall rate of malignancy was 3.5% (15/430). When lesions exhibited delayed washout enhancing kinetics (P < .001), were located ipsilaterally (P = .007), and closer to the primary tumor (P = .012), the possibility of malignancy was high. High T2-weighted imaging signal intensity suggested benignity (P = .043).Although the probability of being diagnosed with malignancy during follow-up in this study was low (0.3%), this investigation revealed several preoperative MRI characteristics that should alert clinicians to the possibility of malignancy.

The objective was to quantify the prevalence of dual diagnosis and to evaluate the characteristics of these patients from community mental health and substance misuse services in Madrid. The sample consisted of 837 outpatients from Madrid, 208 from mental health services and 629 from substance misuse services. We used the Mini International Neuropsychiatric Interview (MINI) and Personality Disorder Questionnaire (PDQ4+) to evaluate disorders from axis I and II. It was considered that 517 (61.8%) patients had dual pathology (current diagnoses of axis I or II disorders and an addictive disorder): 36,1% in mental health services and 70,3% in substance misuse services. There were fewer males amongst the dual patients and it was also found that they had a worse employment situation, along with higher figures of alcohol and cannabis dependence than addicts without dual diagnoses (n=194). When comparing them with patients with mental disorder diagnoses only, excluding substance use disorder (n=126), there were differences in all socio-demographic characteristics analyzed, and dual patients were associated with diagnoses of bipolar disorder, agoraphobia, generalized anxiety disorder, post-traumatic stress disorder, and had more suicide risk and different personality disorders. Thus, dual pathology is higher in patients who are in treatment and have differential characteristics (higher suicide risk, worse employment situation) that suggest greater severity that could be of help in the planning of care resource policies for these patients.

The Value of Ensari's Proposal in Evaluating the Mucosal Pathology of Childhood Celiac Disease: Old Classification versus New Version.

PubMed

Güreşci, Servet; Hızlı, Samil; Simşek, Gülçin Güler

2012-09-01

Small intestinal biopsy remains the gold standard in diagnosing celiac disease (CD); however, the wide spectrum of histopathological states and differential diagnosis of CD is still a diagnostic problem for pathologists. Recently, Ensari reviewed the literature and proposed an update of the histopathological diagnosis and classification for CD. In this study, the histopathological materials of 54 children in whom CD was diagnosed at our hospital were reviewed to compare the previous Marsh and Modified Marsh-Oberhuber classifications with this new proposal. In this study, we show that the Ensari classification is as accurate as the Marsh and Modified Marsh classifications in describing the consecutive states of mucosal damage seen in CD. Ensari's classification is simple, practical and facilitative in diagnosing and subtyping of mucosal pathology of CD.

Large structured databases of pathology findings are valuable in deriving new clinical insights. However, they are labor intensive to create and generally require manual annotation. There has been some work in the bioinformatics community to support automating this work via machine learning in English. Our contribution is to provide an automated approach to construct such structured databases in Chinese, and to set the stage for extraction from other languages. We collected 2104 de-identified Chinese benign and malignant breast pathology reports from Hunan Cancer Hospital. Physicians with native Chinese proficiency reviewed the reports and annotated a variety of binary and numerical pathologic entities. After excluding 78 cases with a bilateral lesion in the same report, 1216 cases were used as a training set for the algorithm, which was then refined by 405 development cases. The Natural language processing algorithm was tested by using the remaining 405 cases to evaluate the machine learning outcome. The model was used to extract 13 binary entities and 8 numerical entities. When compared to physicians with native Chinese proficiency, the model showed a per-entity accuracy from 91 to 100% for all common diagnoses on the test set. The overall accuracy of binary entities was 98% and of numerical entities was 95%. In a per-report evaluation for binary entities with more than 100 training cases, 85% of all the testing reports were completely correct and 11% had an error in 1 out of 22 entities. We have demonstrated that Chinese breast pathology reports can be automatically parsed into structured data using standard machine learning approaches. The results of our study demonstrate that techniques effective in parsing English reports can be scaled to other languages.

Thermal Injuries in Veterinary Forensic Pathology.

Localized thermal injuries in animals may be caused by exposure to fire and radiant heat, contact with hot items including hot liquids or steam, inhalation of hot air, and exposure to cold temperatures. In addition, animal fire victims may have intoxications caused by smoke gas. This article reviews the causes, pathogenetic aspects, morphological findings, additional investigations, differential diagnoses, and causes of death in various forms of thermal injuries. Since these cases do not occur frequently in diagnostic pathology, they represent a challenging task in general but also with respect to forensic or criminal aspects, such as whether a lesion represents an accidental or nonaccidental effect. Besides detailed information about the circumstances at the location, thermal injuries in animals require a thorough morphological evaluation, including additional investigations in conjunction with a profound knowledge about the possible lesion spectrum and suitable additional investigations. © The Author(s) 2016.

Diagnosis and treatment of gastroesophageal reflux disease complicated by Barrett's esophagus.

2017-08-31

The aim of the study was to evaluate the effectiveness of a diagnostic and therapeutic algorithm for gastroesophageal reflux disease complicated by Barrett's esophagus in 46 patients. A diagnostic and therapeutic algorithm for complicated GERD was developed. To describe the changes in the esophagus with reflux esophagitis, the Los Angeles classification was used. Intestinal metaplasia of the epithelium in the lower third of the esophagus was assessed using videoendoscopy, chromoscopy, and biopsy. Quality of life was assessed with the Gastro-Intestinal Quality of Life Index. The used methods were modeling, clinical, analytical, comparative, standardized, and questionnaire-based. Results and their discussion. Among the complications of GERD, Barrett's esophagus was diagnosed in 9 (19.6 %), peptic ulcer in the esophagus in 10 (21.7 %), peptic stricture of the esophagus in 4 (8.7 %), esophageal-gastric bleeding in 23 (50.0 %), including Malory-Weiss syndrome in 18, and erosive ulcerous bleeding in 5 people. Hiatal hernia was diagnosed in 171 (87.7 %) patients (sliding in 157 (91.8%), paraesophageal hernia in 2 (1.2%), and mixed hernia in 12 (7.0%) cases). One hundred ninety-five patients underwent laparoscopic surgery. Nissen fundoplication was conducted in 176 (90.2%) patients, Toupet fundoplication in 14 (7.2%), and Dor fundoplication in 5 (2.6%). It was established that the use of the diagnostic and treatment algorithm promoted systematization and objectification of changes in complicated GERD, contributed to early diagnosis, helped in choosing treatment, and improved quality of life. Argon coagulation and use of PPIs for 8-12 weeks before surgery led to the regeneration of the mucous membrane in the esophagus. The developed diagnostic and therapeutic algorithm facilitated systematization and objectification of changes in complicated GERD, contributed to early diagnosis, helped in choosing treatment, and improved quality of life.

The diagnosis of gastro-esophageal reflux disease cannot be made with barium esophagograms.

For over 50 years, barium studies have been used to diagnose gastro-esophageal reflux disease (GERD), but the value of this test is controversial. Our study aimed to determine if barium esophagograms can be used to diagnose GERD. Barium esophagograms and pH-impedance measurement were performed in 20 subjects with reflux symptoms. pH-impedance measurements were used as gold standard for the diagnosis of GERD. Gastro-esophageal reflux measured with the barium study was defined as a positive outcome. 50% of patients presented gastro-esophageal reflux on the barium esophagogram. No significant differences were observed in acid exposure time between subjects with (median: 7.4%; interquartile range, IQR: 8.4%) or without reflux at barium esophagography (median: 5.95%; IQR: 13.05%; p > 0.05). Nor did we find differences in median proximal extent of reflux measured with impedance monitoring between patients with a positive (median: 6.7%; IQR: 1.95%) and negative barium study (median: 7.1%; IQR: 0.68%; p > 0.05). Patients with reflux on barium esophagogram did not have a positive symptom association probability more often than those who did not have reflux at barium esophagography. Lastly, there were no differences in numbers of acid, weakly acidic or total reflux episodes between those with positive or negative barium esophagogram (p > 0.05). No correlations were found between the maximum proximal extent of gastro-esophageal reflux during esophagography and pH-impedance parameters. Presence or absence of gastro-esophageal reflux during barium esophagography does not correlate with incidence or extent of reflux observed during 24-h pH-impedance monitoring and is not of value for the diagnosis of GERD. © 2014 John Wiley & Sons Ltd.

The European Veterinary Renal Pathology Service (EVRPS) is the first Web-based registry for canine renal biopsy specimens in Europe. The aim was to verify whether differences exist between the clinical and laboratory presentation of dogs with nephropathy according to renal pathological findings, as defined by light and electron microscopy of renal biopsy specimens submitted to EVRPS. Renal biopsy specimens of dogs were collected from the archive of the service (n = 254). Cases were included if both light and electron microscopy were available (n = 162). Renal biopsy specimens were classified based on the morphological diagnoses. Thereafter, they were grouped into 3 disease categories, including immune-complex-mediated glomerulonephritis (ICGN), non-immune-complex-mediated GN (non-ICGN), and renal lesions not otherwise specified (RL-NOS). Differences among morphological diagnoses and among disease categories were investigated for clinical and laboratory variables. Serum albumin concentration was lower in dogs with ICGN than in those with non-ICGN (P = 0.006) or RL-NOS (P = 0.000), and the urine protein-to-creatinine ratio (UPC) was significantly higher in ICGN than in the other 2 disease categories. Regarding morphological diagnoses, albumin was significantly lower in amyloidosis (AMY) and membranous (MGN), membranoproliferative (MPGN) or mixed glomerulonephritis (MixGN) than in minimal change disease, primary (FSGS I) or secondary (FSGS II) focal and segmental glomerulosclerosis and juvenile nephropathies (JN). The UPC was higher in MPGN than in FSGS I and FSGS II. Dogs with ICGN, in particular MPGN, had higher protein loss than those with non-ICGN or RL-NOS, leading to more severe hypoalbuminemia. Clinical and laboratory differentiation among dogs with the different morphological diagnoses and among dogs with different disease categories was difficult due to overlapping results.

Medical errors in pathological diagnosis give a huge amount of physical and psychological damage to patients as well as medical staffs. We discussed here how to avoid medical errors in surgical pathology laboratory through our experience. Handling of surgical specimens and diagnosing process requires intensive labor and involves many steps. Each hospital reports many kinds of accidents or incidents, however, many laboratories share common problems and each process has its specific risk for the certain error. We analyzed the problems in each process and concentrated on avoiding misaccessioning, mislabeling, and misreporting. We have made several changes in our system, such as barcode labels, digital images of all specimens, putting specimens in embedding cassettes directly on the endoscopic biopsied specimens, and using a multitissue control block as controls in immunohistochemistry. Some problems are still left behind, but we have reduced the errors by decreasing the number of artificial operation as much as possible. A pathological system recognizing the status of read or unread the pathological reports by clinician are now underconstruction. We also discussed about quality assurance of diagnosis, cooperation with clinicians and other comedical staffs, and organization and method. In order to operate riskless work, it is important for all the medical staffs to have common awareness of the problems, keeping careful observations, and sharing all the information in common. Incorporation of an organizational management tool such as ISO 15189 and utilizing PDCA cycle is also helpful for safety management and quality improvement of the laboratory.

Diagnosing co-occurring substance-related disorders: agreement between SCID, Hispanic clinicians, and Non-Hispanic clinicians.

Given the composition of the mental health and substance abuse workforce in the United States, Hispanic immigrants are often assigned to non-Hispanic, English-speaking clinicians. This produces challenges in communication and in understanding linguistic and cultural nuances and greatly impacts the accuracy of diagnoses and the delivery of appropriate services. With the inclusion of objective criteria in diagnostic categories, clinician-to-clinician agreement ought not to be impacted by the ethnicity of the client or the clinician. Both practice and research, however, suggest that this is not the case, particularly when diagnosing co-occurring mental health and substance abuse disorders. We explored the degree to which Hispanic and non-Hispanic clinicians agreed with each other and with the Structured Clinical Interview for DSM-IV-TR, Research Version (SCID) when diagnosing co-occurring substance-related disorders. Using a naturalistic design, 88 adult clients were videotaped in diagnostic intake interviews (utilizing the DSM-IV-TR) with Hispanic or non-Hispanic clinicians. Videotapes were then viewed and rated by clinicians who were ethnically cross-matched to those on tape. Clients were also administered the SCID. Data were collected from September 15, 2003, through February 7, 2005. Non-Hispanic clinicians diagnosed significantly more substance-related disorders than Hispanic clinicians, and both Hispanic and non-Hispanic clinicians significantly under-diagnosed substance-related diagnoses compared to the SCID. Clinicians had very low diagnostic reliability with each other and with the SCID. Implications for the assessment, diagnosis, and treatment of co-occurring substance-related disorders are discussed. Findings seem to concur with past research suggesting that clinicians may be influenced by factors other than the diagnostic criteria (e.g., cultural and social biases) when diagnosing, and that they may make erroneous attributions of pathology when diagnosing

Molecular pathology is an essential element of pathology training. As more molecular tests have become available, there is an increasing need for pathology trainees to receive a strong foundation in molecular pathology. Appointed by the Training and Education Committee of the Association for Molecular Pathology, the Molecular Curriculum Task Force has developed a suggested curriculum in molecular pathology for residents. The foundations of molecular pathology are presented as a series of goals and objectives that residency programs can use to develop their educational programs. As pathologists continue to expand their roles to include regular clinical consultations in the realm of molecular testing, a strong foundation in molecular pathology and genomic medicine has become essential to the practice of pathology.

Connecting Eating Pathology with Risk for Engaging in Suicidal Behavior: The Mediating Role of Experiential Avoidance.

PubMed

Skinner, Kayla D; Rojas, Sasha M; Veilleux, Jennifer C

2017-02-01

Individuals with eating pathology, particularly those with diagnosed eating disorders, are at high risk for suicide. It is less clear whether undiagnosed eating pathology and subsyndromal eating disorders carry the same risk and, if so, what mechanisms may explain why higher levels of eating pathology yield greater risk for engaging in suicidal behaviors. The indirect relationship between disordered eating and risk for suicidal behaviors via facets of experiential avoidance was tested using a multiple-mediator model. The model was tested using bootstrapping estimates of indirect effects in a sample of 218 noncollege student adults (Mage = 32.33, 66.1% women) with a history of suicidal attempt and/or history of nonsuicidal self-injury (NSSI). Results revealed that disordered eating indirectly predicted risk for suicidal behaviors, distress aversion (i.e., negative attitudes or dislike of distress), and procrastination (i.e., delaying engagement with distressing activities). Results suggest that targeting experiential avoidance and helping those who have a history of engaging in suicidal behaviors and/or NSSI develop regulation strategies to use during times of distress may be of utmost importance for treatment and prevention of eating pathology. © 2016 The American Association of Suicidology.

Wireless pH-monitoring is an accurate method for diagnosing adults with gastroesophageal reflux disease (GERD). The aim of this study was to evaluate the use of the Bravo capsule on children investigated for GERD in terms of safety, tolerability and feasibility before and after administration of proton pump inhibitors. A Bravo capsule was inserted during upper endoscopy under general anaesthesia or deep sedation with propofol. 48-hour pH-metry was performed in 106 children (50 males, 56 females) at the median age of 11 years (range 17 months-18 years). On the second day of investigation, proton pump inhibitor (PPI) was given at a mean dose of 1.6 mg/kg (SD ±0.6 mg). The definition of GERD was set to a reflux index (RI) of ≥5% and DeMeester score (DMS) ≥14.7. Application of the capsule was successful in 103 of the 106 children (97.2%) and interpretable in 99 of these 103 (96.1%). 49 of the children with interpretable results (49.5%) had GERD according to RI, while 51 (56.7%) had GERD according to DMS. After PPI was given on day 2, RI decreased from a median of 4.9% (range 0.3-63.4%) to 2.2% (0-58.0%), while DMS decreased from a median of 17.6 (range 2.2-207.6) to 8.2 (0.3-178.6), respectively (p < 0.0001). No severe adverse events were reported. Wireless pH-metry is a safe and tolerable method when investigating children for GERD. PPI given on the second day of assessment provides additional information on response to treatment suggesting that pH-metry preferably should be extended to 48 hours.

OBJECTIVES Risk factors for Barrett’s esophagus include gastroesophageal reflux disease (GERD) symptoms, age, abdominal obesity, and tobacco use. We aimed to develop a tool using these factors to predict the presence of Barrett’s esophagus. METHODS Male colorectal cancer (CRC) screenees were recruited to undergo upper endoscopy, identifying newly diagnosed cases of Barrett’s esophagus. Logistic regression models predicting Barrett’s esophagus using GERD symptoms alone and together with abdominal obesity, tobacco use, and age were compared. RESULTS Barrett’s esophagus was found in 70 (8.5%) of 822 CRC screenees. Mutually adjusting for other covariates, Barrett’s esophagus was associated with weekly GERD (odds ratio (OR) = 2.33, 95% confidence interval (Cl)=1.34, 4.05), age (OR per 10 years = 1.53, 95% CI = 1.05, 2.25), waist-to-hip ratio (OR per 0.10 = 1.44, 95% Cl=0.898, 2.32) and packyears of cigarette use (OR per 10 pack-years = 1.09, 95% CI = 1.04, 1.14). A model including those four factors had a greater area under the receiver operating characteristics curve than did a model based on GERD frequency and duration alone (0.72 vs. 0.61, P<0.001), and it had a net reclassification improvement index of 19–25%. CONCLUSIONS The prevalence of Barrett’s esophagus was substantial in our population of older overweight men. A model based on GERD, age, abdominal obesity, and cigarette use more accurately classified the presence of Barrett’s esophagus than did a model based on GERD alone. Following validation of the tool in another population, its use in clinical practice might improve the efficiency of screening for Barrett’s esophagus. PMID:23318485

Traditionally organized gross pathology reports, which are widely used in pathology resident and pathologists' assistant training programs, may not offer the most efficient method of communicating pertinent information to treating physicians. Instructional materials for teaching gross pathology dictation are limited and the teaching methods used are inconsistent. Raymond's Paragraph System, a gross pathology report formatting system, was developed for use at a cancer center and has been implemented at The Methodist Hospital, Houston, Tex, an academic medical center. Unlike traditionally organized reports in which everything is normally dictated in 1 long paragraph, this system separates the dictation into multiple paragraphs creating an organized and comprehensible report. Recent literature regarding formatting of pathology reports focuses primarily on the organization of specimen diagnoses and overall report layout. However, little literature is available that highlights organization of the specimen gross descriptions. To provide instruction to pathologists, pathology residents and fellows, and pathologists' assistant students about an alternative method of organizing gross pathology reports. Review of pertinent literature relating to preparation of gross pathology reports, report formatting, and pathology laboratory credentialing requirements. The paragraph system offers a viable alternative to traditionally organized pathology reports. Primarily, it provides a working model for medical professionals-in-training. It helps create user-friendly pathology reports by giving precise and concise information in a standardized format. This article provides an overview of the system and discusses our experience in its implementation.

Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the fungus Paracoccidioides brasiliensis and is endemic to Brazil. The aim of this study was to perform a retrospective analysis of the PCM cases in the countryside south of Rio Grande do Sul, Brazil. The files from four histopathology laboratories located in the city of Pelotas were obtained, and all of the epidemiological and clinical data from the PCM diagnosed cases were collected for analysis. A total of 123 PCM cases diagnosed between 1966 and 2009 were selected. Of these patients, 104 (84.5%) were male, and 17 were female. The patients ranged from 02 to 92 years of age. Fifty-two cases (41.9%) were obtained from the oral pathology laboratory, and the remaining 71 cases (58.1%) were obtained from the three general pathology laboratories. Of all of the patients studied, 65.2% lived in rural zones and worked in agriculture or other related fields. Data on the evolution of this disease was available for 43 cases, and the time frame ranged from 20 to 2920 days (mean = 572.3 days). An accurate diagnosis performed in less than 30 days only occurred in 21% of the cases. PCM is endemic to the countryside of Rio Grande do Sul. Therefore, it is recommended that PCM be included as a differential diagnosis, mainly for individuals between 30 and 60 years of age, living in rural zones and who have respiratory signs and associated-oropharyngeal lesions.

In developed countries, there has been increased incidental detection of renal cell carcinoma (RCC). The incidence, pathological stage and survival of incidentally detected carcinoma in a developing country in Asia where, from 1990 to 1998, 165 renal cell carcinomas were identified. The clinical presentation, diagnostic-imaging modality employed, pathological staging and patient survival was reviewed. Incidental renal cancers included those that were diagnosed through health screening or detected incidentally through imaging studies for other conditions. The survival between these incidentally detected lesions and their symptomatic counterparts (suspected group) was compared. Sixty-four patients (39%) had their tumours detected incidentally, including 39 who were entirely asymptomatic and 25 who presented with non-specific symptoms, not initially suggestive of RCC. For the entire group, computed tomography provided the definitive diagnosis in 81% of cases. The incidental detection group had significantly smaller size of tumour (5.9 cm c.f. 7.6 cm), lower stage and lower histological grading. In particular, 78% of patients with incidental RCC had stage I or II diseases (TNM stage classification), compared with 57% of patients with suspected tumour (p < 0.05; Chi-square test). The disease free survival was significantly better for those with incidental detection (86% c.f. 66% at last follow up; p < 0.05; log-rank test) over a mean follow up period of 33 months (range 1-91). Regression analysis showed that stage of disease was the only independent variable predictive of clinical outcome. In conclusion, that significant numbers of RCC were detected incidentally. These tumours were of a lower clinical pathological stage and had a better prognosis.

Pathology-related cases in the Norwegian System of Patient Injury Compensation in the period 2010-2015.

2016-12-01

The Norwegian System of Patient Injury Compensation (NPE) processes compensation claims from patients who complain about malpractice in the health services. A wrong diagnosis in pathology may cause serious injury to the patient, but the incidence of compensation claims is unknown, because pathology is not specified as a separate category in NPE’s statistics. Knowledge about errors is required to assess quality-enhancing measures. We have therefore searched through the NPE records to identify cases whose background stems from errors committed in pathology departments and laboratories. We have searched through the NPE records for cases related to pathology for the years 2010 – 2015. During this period the NPE processed a total of 26 600 cases, of which 93 were related to pathology. The compensation claim was upheld in 66 cases, resulting in total compensation payments amounting to NOK 63 million. False-negative results in the form of undetected diagnoses were the most frequent grounds for compensation claims (63 cases), with an undetected malignant melanoma (n = 23) or atypia in cell samples from the cervix uteri (n = 16) as the major groups. Sixteen cases involved non-diagnostic issues such as mix-up of samples (n = 8), contamination of samples (n = 4) or delayed responses (n = 4). The number of compensation claims caused by errors in pathology diagnostics is low in relative terms. The errors may, however, be of a serious nature, especially if malignant conditions are overlooked or samples mixed up.

2009-01-01

Objectives To determine whether a longitudinal, case-based evaluation system can predict acquisition of competency in surgical pathology and how trainees at risk can be identified early. Design Data were collected for trainee performance on surgical pathology cases (how well their diagnosis agreed with the faculty diagnosis) and compared with training outcomes. Negative training outcomes included failure to complete the residency, failure to pass the anatomic pathology component of the American Board of Pathology examination, and/or failure to obtain or hold a position immediately following training. Findings Thirty-three trainees recorded diagnoses for 54 326 surgical pathology cases, with outcome data available for 15 residents. Mean case-based performance was significantly higher for those with positive outcomes, and outcome status could be predicted as early as postgraduate year-1 (P  =  .0001). Performance on the first postgraduate year-1 rotation was significantly associated with the outcome (P  =  .02). Although trainees with unsuccessful outcomes improved their performance more rapidly, they started below residents with successful outcomes and did not make up the difference during training. There was no significant difference in Step 1 or 2 United States Medical Licensing Examination (USMLE) scores when compared with performance or final outcomes (P  =  .43 and P  =  .68, respectively) and the resident in-service examination (RISE) had limited predictive ability. Discussion Differences between successful- and unsuccessful-outcome residents were most evident in early residency, ideal for designing interventions or counseling residents to consider another specialty. Conclusion Our longitudinal case-based system successfully identified trainees at risk for failure to acquire critical competencies for surgical pathology early in the program. PMID:21975705

Gastroesophageal reflux disease (GERD) and psychological stress are associated with sleep disturbances. The aim of the present study was to examine the prevalence of sleep disturbances, anxiety, and depression by GERD subtypes and to identify factors associated with sleep disturbances in general population. A total of 2002 Japanese subjects, who underwent annual health checkups, were enrolled and asked to fill out a questionnaire, including the frequency scale for the symptoms of GERD (FSSG), Athens Insomnia Scale (AIS), Rome III questionnaire, and Hospital Anxiety and Depression Scale (HADS). GERD was divided into asymptomatic erosive reflux disease (a-ERD), symptomatic ERD (s-ERD), and non-erosive reflux disease (NERD), according to the presence or absence of esophageal mucosal injury on endoscopy, and the FSSG scores. Sleep disturbances were diagnosed in subjects with AIS score ≥6. Prevalence of sleep disturbances was significantly higher in GERD subjects than in controls (35.9 and 14.7%, respectively), especially, in the NERD group (45.1%). Sleep duration was significantly shorter in the s-ERD group compared with other groups. Subjects in the NERD and s-ERD groups showed higher HADS scores, resulting in higher incidences of anxiety and depression than those in the control and a-ERD groups. Reflux symptoms, anxiety, depression, and coexisting functional dyspepsia, but not the presence of esophageal mucosal injury, were associated with an increased odds ratio for sleep disturbances. There were significant positive associations among reflux symptoms, psychological stress, and sleep disturbance in Japanese adults. Further studies investigating the efficacy of therapy are needed.

We define the scope and needs within the new discipline of computational pathology, a discipline critical to the future of both the practice of pathology and, more broadly, medical practice in general. To define the scope and needs of computational pathology. A meeting was convened in Boston, Massachusetts, in July 2014 prior to the annual Association of Pathology Chairs meeting, and it was attended by a variety of pathologists, including individuals highly invested in pathology informatics as well as chairs of pathology departments. The meeting made recommendations to promote computational pathology, including clearly defining the field and articulating its value propositions; asserting that the value propositions for health care systems must include means to incorporate robust computational approaches to implement data-driven methods that aid in guiding individual and population health care; leveraging computational pathology as a center for data interpretation in modern health care systems; stating that realizing the value proposition will require working with institutional administrations, other departments, and pathology colleagues; declaring that a robust pipeline should be fostered that trains and develops future computational pathologists, for those with both pathology and nonpathology backgrounds; and deciding that computational pathology should serve as a hub for data-related research in health care systems. The dissemination of these recommendations to pathology and bioinformatics departments should help facilitate the development of computational pathology.

Our objective was to investigate the association between parenting style and eating disorder symptoms in patients treated in an intensive outpatient center for eating disorders. The study design is a cross-sectional survey set in a community-based facility for eating disorders. Participants included 53 families, including 32 with a child meeting the DSM-IV criteria for anorexia nervosa, 18 for bulimia nervosa, and 3 diagnosed ED-NOS. Data was collected using the Parental Authority Questionnaire (PAQ), the Eating Disorders Inventory-2 (EDI-2) and the Eating Attitudes Test (EAT-26). Significant, negative correlations were found between drive for thinness scores and body dissatisfaction scores and the patient's perception of the father as authoritative. Total patient EDI score was significantly and positively correlated with patient's perception of the father as authoritarian and inversely correlated with her perception of him as authoritative. These results emphasize the importance of fathers' role in the eating disorder pathology, a relatively untapped area of research.

Using pathology-specific laboratory profiles in Clinical Pathology to reduce inappropriate test requesting: two completed audit cycles

Background Systematic reviews have shown that, although well prepared, the Consensus Guidelines have failed to change clinical practice. In the healthcare district of Castelnovo né Monti (Reggio Emilia, Italy), it became necessary for the GPs and Clinical Pathologists to work together to jointly define laboratory profiles. Methods Observational study with two cycles of retrospective audit on test request forms, in a primary care setting. Objectives of the study were to develop pathology-specific laboratory profiles and to increase the number of provisional diagnoses on laboratory test request forms. A Multiprofessional Multidisciplinary Inter-hospital Work Team developed pathology-specific laboratory profiles for more effective test requesting. After 8 training sessions that used a combined strategy with multifaceted interventions, the 23 General Practitioners (GPs) in the trial district (Castelnovo nè Monti) tested the profiles; the 21 GPs in the Puianello district were the control group; all GPs in both districts participated in the trial. All laboratory tests for both healthcare districts are performed at the Laboratory located in the trial district. A baseline and a 1-year audit were performed in both districts on the GPs’ request forms. Results Seven pathology-specific laboratory profiles for outpatients were developed. In the year after the first audit cycle: 1) the number of tests requested in the trial district was distinctly lower than that in the previous year, with a decrease of about 5% (p < 0.001); 2) the provisional diagnosis on the request forms was 52.8% in the trial district and 42% in the control district (P < 0.001); 3) the decrease of the number of tests on each request form was much more marked in the trial district (8.73 vs. 10.77; p < 0.001). Conclusions The first audit cycle showed a significant decrease in the number of tests ordered only in the trial district. The combined strategy used in this study improved the

This study was undertaken to determine the prevalence of flat epithelial atypia at ultrasound-guided and stereotactically guided needle biopsies, to describe the mammographic and sonographic features of flat epithelial atypia, and to determine the significance of lesions diagnosed as flat epithelial atypia at imaging-guided needle biopsies. Retrospective review of a database of 1369 consecutive sonographically and stereotactically guided needle biopsies performed during a 12-month period yielded 33 lesions with flat epithelial atypia as the most severe pathologic entity (32 patients). Two radiologists retrospectively reviewed the imaging presentation, by combined consensus, according to the BI-RADS lexicon. Twenty-two of 33 flat epithelial atypia diagnoses (67%) were obtained under stereotactic guidance, and 11 (33%) were obtained under sonographic guidance. Six patients had synchronous breast cancer. Flat epithelial atypia lesions presented mammographically most often as microcalcifications (20/33 [61%]) distributed in a cluster (14/20 [70%]) with amorphous morphology (13/20 [65%]). Sonographically, flat epithelial atypia lesions appeared most often as masses (9/11 [82%]), with an irregular shape (6/9 [67%]), microlobulated margins (5/9 [56%]), and hypoechoic or complex echotexture (7/9 [78%]). Twenty-eight of 33 lesions (85%) were surgically excised, confirming the flat epithelial atypia diagnosis in 11 of the 28 lesions (39%), yielding carcinoma in four (14%) and atypical ductal hyperplasia in six (21%). Columnar cell changes without atypia were diagnosed in four lesions (14%), and lobular carcinoma in situ was diagnosed in three lesions (11%). Mammographic and sonographic presentation of flat epithelial atypia is not specific (clustered amorphous microcalcifications and irregular, hypoechoic or complex masses). Given the underestimation rate of malignancy, surgical excision should be considered when imaging-guided biopsy yields flat epithelial atypia.

Sun Yat-Sen Cancer Center is the only cancer center in Taiwan. The hospital maintains a policy, and the division of oncology makes a concerted effort to obtain and review pertinent pathologic specimens in all patients who had pathologic diagnosis performed at other institution before rendering therapy. A 1-year retrospective study was undertaken to assess the frequency of discordant diagnosis of our second-opinion pathology slide review and determine its impact on patient care. Discrepancies were classified into four basic categories: A) no diagnostic disagreement; B) no diagnostic disagreement but pertinent information not included, such as tumor size, lymphovascular invasion, perineural invasion, histologic grading, margin status, extracapsular spread in metastatic lymph nodes; and C) major diagnostic disagreement, which was defined as follows; 1) change from benign to malignant, 2) change from malignant to benign, 3) a different type of neoplasm, and 4) change in N and M classification in TMN staging framework. Of 715 cases, a total of 673 (94%) showed no discrepancy. However, 35 of 673 (5.2%) cases failed to offer pertinent information (category B). Major disagreement was found in 42 16%) cases (category C). This study illustrated the fact that second pathology slide review prior to therapy can identify a small group of cases that result in a major change in their therapeutic plan. Admittedly, the review of pathology slides involves additional time and effort for both consulting and referring institutions. It can ensure quality medical care and limit medicolegal liability. As the Association of Directors of Anatomic and Surgical Pathology recommended, second pathology review should be standard practice. It is necessary that our major Pathology Association and Societies adopt a strong position on this matter to influence government or insurance company to pay for this service rendered by pathologists.

- Breast magnetic resonance imaging (MRI) is now used routinely for high-risk screening and in the evaluation of the extent of disease in newly diagnosed breast cancer patients. Morphologic characteristics and the kinetic pattern largely determine how suspicious a breast lesion is on MRI. Because of its high sensitivity, MRI identifies a large number of suspicious lesions. However, the low to moderate specificity and the additional cost have raised questions regarding its frequent use. - To identify the pathologic entities that frequently present as suspicious enhancing lesions and to identify specific MRI characteristics that may be predictive of malignancy. - One hundred seventy-seven MRI-guided biopsies from 152 patients were included in the study. The indication for MRI, MRI features, pathologic findings, and patient demographics were recorded. The MRI findings and the pathology slides were reviewed by a dedicated breast radiologist and breast pathologists. - Seventy-one percent (126 of 177) of MRI-guided breast biopsies were benign, 11% (20 of 177) showed epithelial atypia, and 18% (31 of 177) showed malignancy. The vast majority (84%; 62 of 74) of MRI lesions with persistent kinetics were benign. However, 57% (17 of 30) of lesions with washout kinetics and 65% (62 of 95) of mass lesions were also benign. - Magnetic resonance imaging detects malignancies undetected by other imaging modalities but also detects a wide variety of benign lesions. Benign and malignant lesions identified by MRI share similar morphologic and kinetic features, necessitating biopsy for histologic confirmation.

The most common complication after laparoscopic Heller-Dor (LHD) is gastroesophageal reflux disease (GERD). The present study aimed (a) to analyze the true incidence of postoperative reflux by objectively assessing a large group of LHD patients and (b) to see whether the presence of typical GERD symptoms correlates with the real incidence of postoperative reflux. After LHD, patients were assessed by means of a symptom score, endoscopy, esophageal manometry, and 24-h pH monitoring. Patients were assigned to three groups: those did not accept to perform 24-h pH monitoring (group NP); those with normal postoperative pH findings (group A); and those with pathological postoperative acid exposure (group B). Four hundred sixty-three of the 806 LHD patients agreed to undergo follow-up 24-h pH monitoring. Normal pH findings were seen in 423 patients (group A, 91.4 %), while 40 (8.6 %) had a pathological acid exposure (group B). The median symptom scores were similar: 3.0 (IQR 0-8) in group A and 6.0 (IQR 0-10) in group B (p = 0.29). At endoscopy, the percentage of esophagitis was also similar (11 % in group A, 19 % in group B; p = 0.28). This study demonstrated that, after LHD was performed by experienced surgeons, the true incidence of postoperative GERD is very low. The incidence of this possible complication should be assessed by pH monitoring because endoscopic findings and symptoms may be misleading.

Brain injuries are becoming increasingly common in athletes and represent an important diagnostic challenge. Early detection and management of brain injuries in sports are of utmost importance in preventing chronic neurological and psychiatric decline. These types of injuries incurred during sports are referred to as mild traumatic brain injuries, which represent a heterogeneous spectrum of disease. The most dramatic manifestation of chronic mild traumatic brain injuries is termed chronic traumatic encephalopathy, which is associated with profound neuropsychiatric deficits. Because chronic traumatic encephalopathy can only be diagnosed by postmortem examination, new diagnostic methodologies are needed for early detection and amelioration of disease burden. This review examines the pathology driving changes in athletes participating in high-impact sports and how this understanding can lead to innovations in neuroimaging and biomarker discovery.

We conducted a population-based patterns of care study of vulvar carcinoma. This paper describes the changes in reporting based on pathology review. This is a retrospective population-based cohort study. We obtained all pathology records available from the provincial cancer registry for primary invasive squamous cell carcinoma of the vulva diagnosed between 1998 and 2007. Pathology reviews were conducted centrally by a group of gynecologic pathologists and were identified during abstraction. Corresponding original reports were matched to pathology review reports based on accession numbers. We compared the reported value for presence/absence of invasion, grade, depth, thickness, size, lymphovascular space invasion, peripheral margin status, and deep margin status in the original and review report. A total of 1011 vulvar resection reports were identified. From these, we identified 316 pairs of original/review reports. Missing data were common but improved in the reviews. In total, 55 (17%) reports had at least 1 change from the original to the review based on presence of invasion, depth, lymphovascular space invasion, or margin. When we included reports where a variable was missing in the original but then completed in the review, there were clinically relevant changes in 210 reports (66%). Vulvar carcinoma is a rare diagnosis and pathology reviews resulted in potentially important clinical changes in a significant proportion of cases. Referral pathologists play an important role in contributing to high-quality clinical decisions.

For asymptomatic benign papillomas detected at ultrasonography-guided 14-gauge core-needle biopsy (US-CNB), the decision to perform excision versus observation has been a topic of debate. We sought to determine which subgroup of asymptomatic benign papillomas without atypia diagnosed at US-CNB can be safely managed by observation versus immediate excision. Overall, 230 asymptomatic benign papillomas in 197 women (mean age 46.6 ± 9.5 years; range 22-78), diagnosed at US-CNB using immunohistochemistry staining when needed and then managed by surgery (n = 144) or vacuum-assisted excision (VAE) with at least 12 months of follow-up after benign VAE results (n = 86) were included in this study. The upgrade rate to malignancy was calculated. Clinical and radiological variables, including age, size, Breast Image Reporting and Data System (BI-RADS) category, and imaging-pathology correlation were evaluated to find associations with malignancy using multivariate analysis. The upgrade rate to malignancy was 2.6 % (6 of 230): four were ductal carcinomas in situ and two were 1.5- and 9-mm-sized invasive ductal carcinomas without lymph node metastasis. The upgrade rates of papillomas with a BI-RADS category 3-4a and imaging-pathology concordance were 1.4 and 1.8 %, respectively. Category 4b-5 and imaging-pathology discordance were independently associated with malignancy, with upgrade rates of 13 and 50 %, respectively. Age and lesion size were not associated with malignancy. Asymptomatic benign papillomas with probable benign or low suspicious US features or imaging-pathology concordance can be followed-up as opposed to immediate excision.

ᅟ: Obesity is a global epidemic and will soon become the number one priority in healthcare management. Bariatric surgery causes a significant improvement in obesity and its related complications. Pre-operative esophago-gastro-duodenoscopy (EGD) is done by several bariatric surgical teams across the world but is still not mandatory. To study the percentage of symptomatic and asymptomatic pathological EGD findings in obese patients undergoing bariatric surgery and to analyze whether these findings influence the eventual choice of bariatric surgery. All patients posted for bariatric surgery at our institute from January 2015 to March 2017 had a pre-operative EGD done by the same team of endoscopists. In this study, totally, 675 patients were assessed prior to routine bariatric surgery. 78.52% of all pre-operative patients had an abnormal EGD. The most common endoscopic abnormalities found were hiatus hernia (52.44%), gastritis (46.22%), presence of Helicobacter (H.) pylori (46.67%), reflux esophagitis (16.89%), Barrett's esophagus (1.78%), gastric erosions (13.19%), and polyps (7.41%). Fifty patients had upper gastrointestinal polyps: 41 in the stomach, 3 in the esophagus, and 6 in the duodenum, mostly benign hyperplastic or inflammatory polyps. Two patients had gastrointestinal stromal tumor (GIST), 6 leiomyoma, and 6 neuroendocrine tumors (NET). Of those with endoscopic evidence of gastroesophageal reflux disease (GERD), 70 (60.03%) of patients were asymptomatic. The pre-operative EGD findings resulted in a change of the planned surgical procedure in 67 (9.93%) patients. Our study suggests that a large percentage of patients undergoing bariatric surgery have pathologically significant endoscopic findings of which a significant number are asymptomatic; this can lead to a change in the planned bariatric procedure in a section of patients; hence, we believe that EGD should be made mandatory as a pre-operative investigation in all bariatric surgery patients.

[Once again: theoretical pathology].

Theoretical pathology refers to the attempt to reintroduce methodical approaches from the humanities, philosophical logic and "gestalt philosophy" into medical research and pathology. Diseases, in particular disease entities and more complex polypathogenetic mechanisms of disease, have a "gestalt quality" due to the significance of their pathophysiologic coherence: they have a "gestalt". The Research group Theoretical Pathology at the Academy of Science in Heidelberg are credited with having revitalized the philosophical notion of "gestalt" for morphological and pathological diagnostics. Gestalt means interrelated schemes of pathophysiological significance in the mind of the diagnostician. In pathology, additive and associative diagnostic are simply not possible without considering the notion of synthetic entities in Kant's logic.

A case is reported of a 20-year-old woman with generalized severe gingival overgrowth covering almost all of the teeth with diastemata, diagnosed as idiopathic gingival fibromatosis. After initial therapy, the patient underwent surgery consisting of a full-mouth internal beveled gingivectomy. Postoperatively, the maxillary anterior teeth spontaneously moved to almost optimal positions. Removing the cause by gingivectomy can lead to spontaneous correction of the pathologic tooth migration. With supportive periodontal treatment, the patient showed no recurrence of gingival enlargement or repositioning of the teeth at the 5-year follow-up.

Transactivating responsive sequence (TAR) DNA-binding protein 43-kDa (TDP-43) pathology has been described in various brain diseases, but the full anatomical distribution and clinical and biological implications of that pathology are incompletely characterized. Here, we describe TDP-43 neuropathology in the basal forebrain, hypothalamus, and adjacent nuclei in 98 individuals (mean age, 86 years; median final mini-mental state examination score, 27). On examination blinded to clinical and pathologic diagnoses, we identified TDP-43 pathology that most frequently involved the ventromedial basal forebrain in 19 individuals (19.4%). As expected, many of these brains had comorbid pathologies including those of Alzheimer disease (AD), Lewy body disease (LBD), and/or hippocampal sclerosis of aging (HS-Aging). The basal forebrain TDP-43 pathology was strongly associated with comorbid HS-Aging (odds ratio = 6.8, p = 0.001), whereas there was no significant association between basal forebrain TDP-43 pathology and either AD or LBD neuropathology. In this sample, there were some cases with apparent preclinical TDP-43 pathology in the basal forebrain that may indicate that this is an early affected area in HS-Aging. We conclude that TDP-43 pathology in the basal forebrain is strongly associated with HS-Aging. These results raise questions about a specific pathogenetic relationship between basal forebrain TDP-43 and non-HS-Aging comorbid diseases (AD and LBD). PMID:26971127

From telepathology to virtual pathology institution: the new world of digital pathology.

Kayser, K; Kayser, G; Radziszowski, D; Oehmann, A

Telepathology has left its childhood. Its technical development is mature, and its use for primary (frozen section) and secondary (expert consultation) diagnosis has been expanded to a great amount. This is in contrast to a virtual pathology laboratory, which is still under technical constraints. Similar to telepathology, which can also be used for e-learning and e-training in pathology, as exemplarily is demonstrated on Digital Lung Pathology (Klaus.Kayser@charite.de) at least two kinds of virtual pathology laboratories will be implemented in the near future: a) those with distributed pathologists and distributed (> or = 1) laboratories associated to individual biopsy stations/surgical theatres, and b) distributed pathologists (usually situated in one institution) and a centralized laboratory, which digitizes complete histological slides. Both scenarios are under intensive technical investigations. The features of virtual pathology comprise a virtual pathology institution (mode a) that accepts a complete case with the patient's history, clinical findings, and (pre-selected) images for first diagnosis. The diagnostic responsibility is that of a conventional institution. The Internet serves as platform for information transfer, and an open server such as the iPATH (http://telepath.patho.unibas.ch) for coordination and performance of the diagnostic procedure. The size and number of transferred images have to be limited, and usual different magnifications have to be used. The sender needs to possess experiences in image sampling techniques, which present with the most significant information. A group of pathologists is "on duty", or selects one member for a predefined duty period. The diagnostic statement of the pathologist(s) on duty is retransmitted to the sender with full responsibility. The first experiences of a virtual pathology institution group working with the iPATH server working with a small hospital of the Salomon islands are promising. A centralized

In spite of considerable progress in neuropathological research on Alzheimer's disease (AD), knowledge regarding the exact pathoanatomical distribution of the tau cytoskeletal pathology in the thalamus of AD patients in the advanced Braak and Braak AD stages V or VI of the cortical cytoskeletal pathology is still fragmentary. Investigation of serial 100 μm-thick brain tissue sections through the thalamus of clinically diagnosed AD patients with Braak and Braak AD stage V or VI cytoskeletal pathologies immunostained with the anti-tau AT8 antibody, along with the affection of the extraterritorial reticular nucleus of the thalamus, reveals a consistent and severe tau immunoreactive cytoskeletal pathology in the limbic nuclei of the thalamus (e.g., paraventricular, anterodorsal and laterodorsal nuclei, limitans-suprageniculate complex). The thalamic nuclei integrated into the associative networks of the human brain (e.g., ventral anterior and mediodorsal nuclei) are only mildly affected, while its motor precerebellar (ventral lateral nucleus) and sensory nuclei (e.g., lateral and medial geniculate bodies, ventral posterior medial and lateral nuclei, parvocellular part of the ventral posterior medial nucleus) are more or less spared. The highly stereotypical and characteristic thalamic distribution pattern of the AD-related tau cytoskeletal pathology represents an anatomical mirror of the hierarchical topographic distribution of the cytoskeletal pathology in the interconnected regions of the cerebral cortex of AD patients. These pathoanatomical parallels support the pathophysiological concept of a transneuronal spread of the disease process of AD along anatomical pathways. The AD-related tau cytoskeletal pathology in the thalamus most likely contributes substantially to the neuropsychiatric disease symptoms (e.g., dementia), attention deficits, oculomotor dysfunctions, altered non-discriminative aspects of pain experience of AD patients, and the disruption of their

Premature ovarian insufficiency (POI) is defined as a cessation of function of ovaries in women younger than 40 years old. Brain-derived neurotrophic factor (BDNF) is a protein critically involved in neuronal growth and metabolism. BDNF also has been shown to be important regulator of oocyte maturation. Recent data show that BDNF can be potentially involved in POI pathology. The aim of the study was to assess the BDNF plasma concentrations in patients diagnosed with idiopathic POI. 23 women diagnosed with POI (age 31 ± 7 years) and 18 (age 31 ± 3) controls were included to the study, matched according to age and body mass index. The BDNF concentrations were measured using competitive enzyme-linked immunosorbent assay (ELISA). Hormonal and metabolic parameters were measured in all individuals, in controls in late follicular phase. The POI group demonstrated lower mean plasma concentrations of BDNF (429.25 ± 65.52 pg/ml) in comparison to healthy controls (479.75 ± 34.75 pg/ml, p = 0.0345). The BDNF plasma concentration correlated negatively (R = -0.79, p < 0.001) with number of months since last menstrual period. There was a positive correlation between BDNF and progesterone in controls. In conclusion, POI patients show significantly lower BDNF plasma concentration and it correlates with the duration of amenorrhea. This observation brings important potential insights to the pathology of POI.

This study was conducted to provide sonographic measurements of the abdominal esophagus length in neonates and infants with and without gastroesophageal reflux disease (GERD) and to investigate its diagnostic value. GERD severity was also evaluated and correlated with esophageal length. It is a prospective case-control study. This prospective case-control study comprised 235 neonates and infants (120 without reflux and 115 with reflux). There were 40 children without reflux in each of three age categories: less than 1 month, 1-6 months, and 6-12 months. Of the children with reflux, 40 were less than 1 month old; 37, 1-6 months; and 38, 6-12 months. The abdominal esophagus was measured from its entrance into the diaphragm to the base of gastric folds in fed infants. GERD was sonographically diagnosed and confirmed by a barium meal. The number of refluxes during a 10-min period were recorded. Neonates and infants with reflux had a significantly shorter abdominal esophagus than subjects without reflux: the mean difference in neonates, 4.65 mm; 1-6 months, 4.57 mm; 6-12 months, 3.61 mm. Children with severe reflux had a shorter esophagus compared with those with mild and moderate reflux only in the neonate group. Therefore, thinking of GERD and carefully looking for its symptoms is necessary to avoid unnecessary utilization of healthcare resources in children with severe reflux.

The purpose of this study was to evaluate the prevalence of cold sensitivity in patients with hand- and wrist-related diagnoses. We included English-speaking adults who were more than 1 month following hand injury or onset of symptoms. Patients were asked if exposure to cold air or water provoked cold-related symptoms and to rank symptom severity (scale 0-10). Statistical analyses evaluated the relationships between the cold sensitivity and independent variables (age, gender, history of trauma, and time from injury/symptoms). There were 197 patients (mean age 49 ± 16 years): 98 trauma and 99 non-trauma cases. Cold-induced symptoms were reported by 34 %, with 10 % reporting severe symptoms. Exposure to cold air is the most common catalyst; mean severity score was 6.7 ± 2.2. Those with traumatic injuries compared to non-trauma diagnoses reported significantly more cold-induced symptoms (p = .04). Using backward linear regression, the significant predictors of cold symptom severity were trauma (p = .004) and time since onset (p = .003). Including only the trauma patients in the regression model, the significant predictor was time since injury (p = .005). Cold-induced symptoms are reported by more than 30 % of hand-related diagnoses, and exposure to cold air was the most commonly reported trigger. The significant predictors of cold-induced symptoms are traumatic injuries and longer time from injury. This study provides evidence of the common problem of cold sensitivity in patients with hand pathology. Prognostic Level II.

The modern ultrasound dopplerography give us the big possibilities in investigation of gemodynamical changes in all stages of abdomen pathology. Many of researches devoted to using of noninvasive methods in practical medicine. Now ultrasound Dopplerography is one of the basic one. We investigated 250 patients from 30 to 77 ages, including 149 men and 101 women. The basic diagnosis of all patients was the Ischaemic Pancreatitis. The Second diagnoses of pathology were the Ischaemic Disease of Heart, Gypertension, Atherosclerosis, Diabet, Vascular Disease of Extremities. We researched the abdominal aorta and her branches: Arteria Mesenterica Superior (AMS), truncus coeliacus (TC), arteria hepatica communis (AHC), arteria lienalis (AL). For investigation we use the following equipment: ACUSON 128 XP/10c, BIOMEDIC, GENERAL ELECTRIC (USA, Japan). We analyzed the following componetns of gemodynamical changes of abdominal vessels: index of pulsation, index of resistance, ratio of systol-dystol, speed of blood circulation. Statistical program included the following one: 'basic statistic's,' 'analytic program.' In conclusion we determined that the all gemodynamical components of abdominal vessels had considerable changes in abdominal ischaemia than in normal situation. Using the computer's program for definition degree of gemodynamical changes, we can recommend the individual plan of diagnostical and treatment program.

A primary intestinal lymphangiectasia patient diagnosed by capsule endoscopy and confirmed at surgery: a case report.

Intestinal lymphangiectasia (IL) is a rare disease characterized by dilated lymphatic vessles in the intestinal wall and small bowel mesentery which induce loss of protein and lymphocytes into bowel lumen. Because it most often occurs in the intestine and cannot be detected by upper gastroendoscopy or colonoscopy, and the value of common image examinations such as X-ray and computerized tomography (CT) are limited, the diagnosis of IL is difficult, usually needing the help of surgery. Capsule endoscopy is useful in diagnosing intestinal diseases, such as IL. We here report a case of IL in a female patient who was admitted for the complaint of recurrent edema accompanied with diarrhea and abdominal pain over the last twenty years, and aggravated ten days ago. She was diagnosed by M2A capsule endoscopy as a primary IL and confirmed by surgical and pathological examination.

The current understanding of associations between lung disease and military deployment to Southwest Asia, including Iraq and Afghanistan, is both controversial and limited. We sought to clarify the relation between military deployment and biopsy-proven lung disease. Retrospective data were analyzed for military personnel with non-neoplastic lung biopsies evaluated at the Armed Forces Institute of Pathology or Joint Pathology Center (January 2005 to December 2012). Of 391 subjects, 137 (35.0%) had deployed to Southwest Asia prior to biopsy. Compared to non-deployed subjects, those deployed were younger (median age 37 vs. 51 years) with higher representation of African Americans (30.0 vs. 16.9%). Deployed patients were more likely diagnosed with non-necrotizing granulomas (OR 2.4). Non-deployed subjects had higher frequency of idiopathic interstitial pneumonias, particularly organizing pneumonia. Prevalence of small airways diseases including constrictive bronchiolitis was low. This study provides a broader understanding of diversity of biopsy-proven non-neoplastic lung disease as it relates to military deployment to Southwest Asia and importantly did not show an increased prevalence of small airway disease to include constrictive bronchiolitis.

Pathology is a discipline of medicine that adds great benefit to aging studies of mice by integrating in vivo, biochemical, and molecular data. It is not possible to diagnose systemic illness, co-morbidities, and proximate causes of death in aging studies without the morphologic context provided by histopathology. To date, many rodent aging studies do not utilize endpoints supported by systematic histopathology, which leaves studies incomplete, contradictory, and difficult to interpret. Similar to traditional toxicity studies, if the effect of a drug, dietary treatment, or altered gene expression on aging is to be studied, systematic pathology analysis must be included to determine the causes of age-related illness, moribundity, and death. In this Commentary we discuss the factors which should be considered in the design of aging studies in mice, with the inclusion of robust pathology practices modified after those developed by toxicologic and discovery research pathologists. Investigators in the field of aging must consider the use of histopathology in their rodent aging studies in this era of integrative and preclinical geriatric science (geroscience). PMID:26792843

Spontaneous regressions of brain stem gliomas are extremely rare. Only six cases have been reported in the literature. We describe the case of a patient who was diagnosed with a pontomedullary dorsal brain stem glioma at the age of 15 years. An open biopsy showed the presence of an anaplastic glioma. Because the patient and her parents refused conventional therapies, including radiation and chemotherapy, we followed up the patient by performing magnetic resonance imaging scans on her every 3 months. At 3 months after biopsy, we observed the radiological disappearance of her tumor. One year after biopsy, the tumor retained the spontaneous complete regression observed earlier. In this case report, we present the first report of the spontaneous complete regression of a brain stem glioma that was histologically proven to be a high-grade glioma and we believe that this regression was the natural progression of this case, as may be the scenario in a few other cases of brain stem gliomas.
