Adaptation of a quality of life questionnaire for Iranian patients with esophageal cancer.

INTRODUCTION: Evaluation of quality of life is very important in cancer patients. Esophagus-specific quality of life questionnaire (QLQ-OES18) is a disease-specific questionnaire for assessing quality of life in esophageal cancer (EC). So we aimed to translate and evaluate the reliability and validity of the QLQ-OES18 when applied to Iranian patients. MATERIALS AND METHODS: This study was designed as cross-sectional study on 62 newly confirmed EC in two referral hospital in Tehran, Iran. Reliability of the subscales was evaluated by intraclass correlation coefficients. Pearson's correlations of an item with its own scale and other scales were calculated to assess convergent and discriminant validity. Clinical validity was also evaluated by known-group comparisons. RESULTS: Cronbach's alpha was higher than 0.7 in most subscales. All subscales met the standards of convergent and discriminant validity. Also QLQ-OES18 had discriminatory power for differentiation between patient's groups with different clinical status. CONCLUSION: Our results provide evidences that Persian version of QLQ-OES18 is a valid and reliable questionnaire when applied to a sample of Iranian patients with EC and is recommended for use in clinical research.

Unusual presentation of transthyretin (ATTR) cardiac amyloidosis: A case report of pruritus as a possible initial symptom and challenging diagnosis.

Key Clinical Message: This case emphasizes the significance of cardiac amyloidosis as a potential diagnosis in individuals manifesting with lesion-free pruritus and normal liver tests. Abstract: Amyloidosis is a complex disorder in which misfolded proteins accumulate in various organs of the body. Cardiac amyloidosis (CA) can lead to heart failure, cardiac arrhythmia, sudden cardiac death, and deposition of proteins in coronary arteries. Diagnosing CA can be difficult, as the cardiac manifestations of amyloidosis can be similar to more prevalent etiologies. In addition, the accumulation of proteins in soft tissues, including the skin, can cause pruritus. In this paper, we present a 70-year-old man with generalized pruritus and no skin lesions, later diagnosed as CA after detecting ascites fluid. This case underscores the importance of considering amyloidosis in patients presenting with nonspecific symptoms, particularly those affecting the skin, and highlights the need for increased awareness of this disease among clinicians.

Dyssynergic Defecation: A Comprehensive Review on Diagnosis and Management.

About one-third of chronically constipated patients have an evacuation disorder, and dyssynergic defecation is a common cause of the evacuation disorder. In dyssynergic defecation, the coordination between abdominal and pelvic floor muscles during defecation is disrupted and patients cannot produce a normal bowel movement. The etiology of dyssynergic defecation is still unknown. Although a detailed history taking and a careful examination including digital rectal examination could be useful, other modalities such as anorectal manometry and balloon expulsion test are necessary for the diagnosis. Biofeedback therapy is one of the most effective and safe treatments. Here, we provide an overview of dyssynergic defecation as well as how to diagnose and manage this condition.

Comparison of the efficacy of diltiazem versus fluoxetine in the treatment of distal esophageal spasm: A randomized-controlled-trial.

BACKGROUND AND STUDY AIM: Distal esophageal spasm is an uncommon esophageal motility disorder presenting with non-cardiac chest pain and dysphagia. The main goal of therapy is symptom relief with pharmacologic, endoscopic, and surgical therapies. Pharmacologic treatment is less invasive and is the preferred method of choice. The purpose of this study was to compare the effectiveness of diltiazem versus fluoxetine in the treatment of distal esophageal spasm. PATIENTS AND METHODS: A total of 125 patients with distal esophageal spasm diagnosed using endoscopy, barium esophagogram, and manometry were evaluated. Patients were divided into diltiazem and fluoxetine groups and received a 2-month trial of diltiazem + omeprazole or fluoxetine + omeprazole, respectively. Of 125 patients, 55 were lost to follow up and 70 were eligible for final analysis. Clinical signs and symptoms were assessed before and after therapy using four validated questionnaires: Eckardt score, short form-36, heartburn score, and the hospital anxiety and depression scale. RESULTS: Both regimens significantly relieved symptoms (a decrease in mean Eckardt score of 2.57 and 3.18 for diltiazem and fluoxetine groups, respectively; and a decrease in mean heartburn score by 0.89 and 1.03 for diltiazem and fluoxetine groups, respectively). Patients' quality of life improved based on short form-36 (an increase in mean score of 2.37 and 3.95 for fluoxetine and diltiazem groups, respectively). There was no relationship between patients' improvement and severity of symptoms. Psychological findings based on the hospital anxiety and depression scale were inconsistent (a decrease in mean of 0.143 and 0.57 for fluoxetine and diltiazem groups, respectively; p > 0.05). CONCLUSION: Fluoxetine and diltiazem were effective for clinical symptom relief in patients with distal esophageal spasm, but were not promising for improving psychological symptoms. Neither regimen was superior in terms of efficacy. Consequently, it is key to consider side effects and comorbidities when choosing a therapy.

Identification of Streptococcus gallolyticus in tumor samples of Iranian patients diagnosed with colorectal cancer.

OBJECTIVE: Clinical outcomes of infection by S. gallolyticus have not been investigated extensively. We aimed to determine the prevalence of S. gallolyticus in tumor specimens obtained from Iranian patients diagnosed with colorectal cancer. Polymerase chain reaction was used to confirm the presence of S. gallolyticus in patients' tissue samples. RESULTS: Of 176 patients, 65 were diagnosed with colorectal cancer whereas 111 did not have any colon disease. No correlation was found between age, colonization with S. gallolyticus, gender, or risk factors. Overall, 72 (40%) patients carried S. gallolyticus; only 29% of the patients without colorectal cancer were positive for S. gallolyticus. Diagnosis of colorectal cancer and presence of S. gallolyticus significantly correlated (P = 0.006; odds ratio = 1.46; 95% CI = 1.21-3.87). Among the patients with colorectal cancer, 39 (60%) were positive with S. gallolyticus (P = 0.006) whereas 33 of 111 (29.7%) control subjects were positive for S. gallolyticus (P > 0.05); thus, 70.3% of the control subjects were not infected with S. gallolyticus. We found a high prevalence of S. gallolyticus among an Iranian cohort of patients with colorectal cancer. Despite previous reports, we report a positive correlation between colorectal cancer and S. gallolyticus colonization.

Novel description on esophageal timed barium swallow: a correlation between advanced parametrization and esophageal X-ray images.

Aim: The TBS-derived image processing method, based on the observer's diagnosis, has been developed in the current investigation. Image parametrization is proposed for both novel description and convergent shreds of evidence. Background: Condensed X-ray images of the esophageal timed barium swallow (TBS) provide substantial implications for elucidating the pathophysiological dimensions of esophageal motility disorders. Methods: Through the simultaneous study on TBS and high-resolution manometry (HRM) findings, we performed a retrospective cohort study on 252 patients from March 2018 to October 2019. Interventions, irrelevant information, and insufficient patient data were excluded. Only subjects with adequate data and acceptable test accuracy were considered for participation. We reviewed 117 Dicom (digital imaging and communications in medicine) X-ray images from patients with confirmed diagnoses of achalasia type II, esophagogastric junction outflow obstruction (EGJOO), or non-achalasia. Results: The results suggested a cut-off level of 47% in DDi (dilated diameter index) as a sign of the dilated body. In achalasia type II patients (n=66 images), the mean DDi was 55.6%. Our method presented a sensitivity of 95% and a specificity of 93% compared to images of the non-achalasia findings. The mean DDi in EGJOO patients was 50.4%, according to the 27 images. Moreover, results from EGJOO patients provided a sensitivity of 85% and specificity of 87%. Conclusion: TBS is an efficacious method and a prominent component in the process of achalasia diagnosis. Standard parametrization might develop radiological exports proposed by DDi. Our method could assist in obtaining a non-invasive medical diagnosis and help advance diagnostic reports to identify achalasia subtypes somewhat earlier. To the best of our knowledge, this interface is an innovative parametrization for TBS image review.

Colonization by Pseudomonas aeruginosa and Staphylococcus aureus of Antral Biopsy Specimens from Gastritis Patients Uninfected with Helicobacter Pylori.

PURPOSE: Roles and incidence of some microorganisms that transiently or permanently colonize the human stomach are still unknown despite advances in gastroenterology. We aimed to examine the incidence of four microorganisms, Helicobacter pylori, Pseudomonas aeruginosa, Staphylococcus aureus, and Staphylococcus epidermidis, in the antral biopsy specimens of patients with gastroduodenal conditions. PATIENTS AND METHODS: Patients (67 females, 33 males; mean age = 49.5 years) were initially examined and diagnosed by a gastroenterologist at the Mehrad Hospital, Tehran, Iran. We enrolled those who underwent the upper gastrointestinal endoscopy because of gastroduodenal conditions. Two antral biopsy samples were taken by endoscopy; the first sample was used for the "rapid urease test" to confirm H. pylori. The second was used for DNA extraction and PCR analyses with specific, corresponding primer sets to establish the presence of the four microorganisms. Our study was approved by the Ethics Committee at the Tarbiat Modares University, Tehran. RESULTS: Based on pathology and endoscopy findings, we divided the patients into three groups: 62 presented with gastritis, 18 with duodenal ulcer, and 20 gastric ulcer. The number of patients with P. aeruginosa but without H. pylori significantly differed from the number of those co-infected with both microorganisms (P = 0.03). Additionally, a similar significance was found between the incidence of S. aureus in patients without H. pylori and those with both infections (P = 0.04). Our results indicated that a significant number of patients with gastritis were colonized with P. aeruginosa or S. aureus without being co-infected with H. pylori (P < 0.001). Interestingly, the incidence of colonization by P. aeruginosa of patients without H. pylori (45/49, 91.8%) was higher than that by S. aureus (28/49, 57%). CONCLUSION: The number of patients without H. pylori but with P. aeruginosa or with S. aureus infection significantly differed from that with both infections, respectively. Our study thus shows that patients without H. pylori infection are prone to be colonized by P. aeruginosa or S. aureus, indicating that targeted antibiotic regimens are necessary for clinically treating them.

Microbial Contamination after Cardiac Surgery in a Hospital Cardiac Surgery Ward.

Surgery site infection is one of the most common postoperative complications which is associated with increased morbidity, mortality and admission costs. It is considered a priority to determine the level of nosocomial infection and its control in reflecting the quality of care. Therefore, this study aimed to evaluate the microbial contamination after cardiac surgery at a hospital cardiac surgery ward of Besat Hospital, Tehran. In this cross-sectional descriptive-analytic study (2013-2017), 610 patients underwent surgery at the Department of Cardiac Surgery of Besat Hospital. All necessary information such as urine culture, surgical site, histopathologic examination for the diagnosis of microbial contamination and microorganisms were collected from the patient records and inserted in the questionnaire. The data were analyzed using SPSS (version 25). The incidence of nosocomial infections following cardiac surgery reportedly ranged from 17% to 23%. Accordingly, pneumonia (51.2%) and local infections (22%) were the most common infections in the studied population. The mortality rate in our population was 11.4%. Moreover, 64.3% of the total mortality cases were reported in patients with sepsis. The mean age and duration of admission of patients with catheter infection were significantly higher than other subjects. Given the relatively high prevalence of the infection and its importance, it is necessary to take more serious measures to prevent and control these infections.

Helicobacter heilmannii Colonization Is Associated with High Risk for Gastritis.

INTRODUCTION: We aimed to study potential associations between colonization by four common non-pylori Helicobacter species and gastroduodenal diseases by comparing samples from patients infected with H. pylori with samples from non-infected subjects. MATERIALS AND METHODS: Patients (n = 190) who were subjected to upper gastrointestinal endoscopy because of gastroduodenal conditions were enrolled in this cross-sectional study. Antral biopsy samples were taken from patients in two major hospitals (Mehrad and Imam-Hossein) in Tehran, Iran, during 2017-2018. DNA was isolated from the biopsy specimens, and PCR amplification was used to identify the Helicobacter species by using their corresponding specific primer sets. RESULTS: Out of 120 cases positive for H. pylori, 46 (38%) were patients with gastritis, 23 (19%) with duodenal ulcer, 11 (9%) with gastric cancer, and 40 (33.3%) with gastric ulcer. Overall, 70 (36%) patients were negative for H. pylori. H. pylori cases were uninfected by any of the other tested Helicobacter species. Among the 70 patients without H. pylori, 34 had gastritis-31 (94%) of these were positive also for H. heilmannii (p = 0.001, Odds Ratio: 51.6; 95% Confidence Intervals: 11.8-225.6). We did not find any patient carrying mixed Helicobacter infections with any non-pylori Helicobacter species in this cohort. CONCLUSIONS: Given our evidence about the possibility of involvement of H. heilmannii in patients suffering from gastritis and nonexistence of mixed non-pylori Helicobacter infections, bacteriological testing of subjects negative for H. pylori becomes clinically relevant and important.

Solitary Rectal Ulcer Syndrome: A Narrative Review.

Solitary rectal ulcer syndrome is a multifactorial pathology, which entails a variety of clinical, histologic and endoscopic aspects that needs step-wise logical approach for management especially in relapsing refractory cases. Apart from the diagnostic dilemma that may be faced due to similarities of presentation with inflammatory bowel diseases or colorectal neoplastic lesions, the syndrome also overlaps with dyssynergic defecation syndrome, health anxiety disorder, obsessive compulsive disorder, and latent mucosal rectal prolapse, a systematic composite treatment modality including psychological, pharmacological, physiological and possibly surgical interventions are sometimes essential. Selecting appropriate treatment in this condition not only affects clinical outcome but also patients' experience and further stigma of SRUS life-long. In this review, we will discuss the detailed pathophysiology, diagnostic and therapeutic approaches in dealing with solitary rectal ulcer syndrome.

Efficacy of Chemoradiotherapy on Health-Related Quality of Life in Esophageal Cancer Patients with Dysphagia.

INTRODUCTION: Esophageal cancer is diagnosed with more than 480,000 patients per year and this disease became the eighth most common cancer worldwide. AIM: In this study, we tried to investigate the role of chemoradiotherapy in decreasing the severity of dysphagia and increasing the quality of life (QOL) in patients with esophageal cancer. METHODS: Patients were diagnosed with esophageal cancer, which were proven by pathological studies. Also, all of these patients had no primary surgeries for their esophageal cancer. For determining the cancer staging, the endoscopy, sonography, abdominal and pelvic computed tomography scans were assessed. RESULTS: In this study, 81% of patients showed responsiveness to the chemoradiotherapy and their dysphagia significantly was getting improved after treatment in comparison to the initial date (P<0.01). Also, the pain score significantly decreased after chemoradiotherapy. However, the analysis failed to show any significant difference between before and after treatment in 19% of patients who had high degrees of dysphagia and they were the candidate for surgery and stent putting. On the other hand, we demonstrated that there is no correlation between sex, age, tumor type and location with the recovery rate of dysphagia. In addition, we showed that none of the patients showed the recurrence of dysphagia during the study (1.5 years). CONCLUSION: Chemoradiotherapy could be a novel treatment for patients with inoperable esophageal cancer to reduce the severity of dysphagia and increasing the QOL of these individuals.

Carrying a 112 bp-segment in Helicobacter pylori dupA may associate with increased risk of duodenal ulcer.

The discovery of Helicobacter pylori in 1983 challenged researchers around the world to identify this pathogen's major virulence factors. The main rationale for this kind of research was to identify a biomarker associated with specific diseases following H. pylori colonization. Among different investigated virulence factors, duodenal ulcer promoting gene A (dupA) has been found to be associated with duodenal ulcer (DU), but its effect was different in various geographical regions. To determine the prevalence of dupA, we applied both classic primer pairs and our newly developed primers producing a highly conserved segment in PCR method. In our survey, 143 (47%) H. pylori isolates were obtained from 304H. pylori-colonized individuals [age range of 19-92; 113 (37%) males with the mean age of 50 and 191 (63%) females with the mean age of 49]. The presence of the dupA gene was investigated by using the different specific primers. The prevalence of the 112 bp segment isolated from H. pylori strains recovered from DU, GU and atrophy groups were significantly higher (81%, p value = .002, 64%, p = .065, 68% and p = .047 38%, respectively) than our control group, where the prevalence of the 112 bp segment was only 38%. Interestingly, a significant relationship was observed between the occurrence of DU and the presence of the 112 bp segment [p = .002; OR: 6.98; (95% CI: 1.94-25.00)]. Taken as a whole, we believe the 112 bp region of H. pylori dupA may serve as the first detected biomarker for the early detection of DU in patients admitted to hospitals.

Solitary rectal ulcer syndrome: A systematic review.

BACKGROUND: Solitary rectal ulcer (SRUS) may mislead the inflammatory bowel disease (IBD) or rectal polyps, which may reduce the actual prevalence of it. Various treatments for SRUS have been described that can be referred to therapeutic strategies such as biofeedback, enema of corticosteroid, topical therapy, and rectal mucosectomy. Nevertheless, biofeedback should be considered as the first stage of treatment, while surgical procedures have been offered for those who do not respond to conservative management and biofeedback or those who have total rectal prolapse and rectal full-thickness. METHODS: A systematic and comprehensive search will be performed using MEDLINE, PubMed, Scopus, EMBASE, AMED, the Cochrane Library, and Google Scholar. RESULTS: The results of this systematic review will be published in a peer-reviewed journal. CONCLUSION: To our knowledge, our study discusses the factors involved in the pathogenesis, clinical symptoms, diagnosis, treatment, and management of patients. This review can provide recommended strategies in a comprehensive and targeted vision for patients suffering from this syndrome.

Chronic constipation: A review of literature.

BACKGROUND: Chronic constipation is described as a common complication determined by difficult and/or rare passage of stool or both. The difference in definition of constipation has led to a wide range of reported prevalence (i.e., between 1% and 80%). Various factors are involved in the pathogenesis of the disease, including type of diet, genetic predisposition, colonic motility, absorption, social economic status, daily behaviors, and biological and pharmaceutical factors. Diagnostic and therapeutic options play a key role in the treatment of chronic constipation. There are still debates about the timing of these diagnostic and therapeutic algorithms. METHODS: A systematic and comprehensive search will be performed using MEDLINE, PubMed, EMBASE, AMED, the Cochrane Library and Google Scholar. Better understanding of the pathophysiology of chronic constipation and efficacy of pharmacological agent can help physicians for treating and managing symptoms.In this study, some of the old and new therapies in the treatment of chronic constipation have been studied based on the controlled studies and strong evidence. We are trying to address some of the controversial issues to manage the disease and to provide appropriate diagnostic options in an efficient and cost-effective way. RESULTS: The results of this systematic review will be published in a peer-reviewed journal. CONCLUSION: To our knowledge, our study will provide an overall estimate of chronic constipation to assess controversial issues, available diagnostic and therapeutic strategies of chronic constipation. ETHICS AND DISSEMINATION: Ethical approval and informed consent are not required, as the study will be a literature review and will not involve direct contact with patients or alterations to patient care.

Advances in the Diagnosis of GERD Using the Esophageal pH Monitoring, Gastro-Esophageal Impedance-pH Monitoring, And Pitfalls.

PH monitoring is not capable of detecting all types of reflux, especially when the amount of acid is very low or not at all in the refluxate. Multichannel intraluminal impedance-pH monitoring (MII-pH) is used as a new method to assess bolus transport. The types of reflexes including acid, weak acid and weak alkaline MII-pH is capable of distinguishing more reflux episodes based upon use of physical and chemical parameters of the refluxate, leads to a diagnosis of normal acid reflux from abnormal nonacidic reflux. 24-h oesophagal pH monitoring can be effectively used to assess the potential relationship between symptoms and refluxes. MII-pH is capable of distinguishing more reflux episodes based upon use of physical and chemical parameters of the refluxate, leads to a diagnosis of normal acid reflux from abnormal nonacidic reflux. It can be used to confirm gastro-oesophagal reflux episodes, where has a sensitivity and specificity for diagnosing GERD in comparison with endoscopy or pH-metry.

Diagnostic Efficacy of 24-hr Esophageal pH Monitoring in Patients with Refractory Gastroesophageal Reflux Disease.

BACKGROUND: Gastric reflux is one of the most important causes of the referral of patients to the internal clinic, which in some cases causes problems for patients due to resistance to common treatments. Therefore, timely diagnosis and treatment of this group of patients are very important. AIM: The purpose of the present study was to determine the off-proton pump inhibitor (off-PPI) 24 h pH-impedance analyses in patients with refractory gastroesophageal reflux disease (GERD) attending to Taleghani Hospital since 2009 to 2017. METHODS: In this observational descriptive-comparative off-PPI study, 572 patients with refractory GERD who were referred to Taleghani Hospital in Tehran from 2009 to 2017 were selected, and the results of 24 h pH Impedance analysis were then assessed. RESULTS: The results of 24h pH-impedance indicated that 7% of cases belonged to Pure Acid Reflux followed by weakly Acid (1%), non-acid (0.3%), mixed & gas (5.2%), functional (58.4%) and oesophagal hypersensitivity (28%). Furthermore, weakly acid plus acid was also found to be 8% and Weakly Acid + Acid + Non-Acid were determined as 8.3%. CONCLUSIONS: Our findings suggested that nearly more than half of the patients with refractory GERD would have a functional disorder in the 24h pH-impedance analysis.

Investigating Esophageal Stent-Placement Outcomes in Patients with Inoperable Non-Cervical Esophageal Cancer.

Background: Esophageal stent insertion in patients with inoperable esophageal cancer is usually accompanied with relatively high adverse symptoms and even mortality. The current study aims at investigating the outcomes of esophageal stenting in patients with inoperable non-cervical esophageal cancer. Materials and Methods: The current descriptive-analytical research evaluates 25 patients with esophageal cancer. The stent was placed in esophagus based upon endoscopy analysis with or without fluoroscopy and then the stent position and its opening was investigated by making use of CXRand Gastrografin studies. Demographic characteristics, dysphagia scores, stent placement side effects and the dysphagia-related indices were recorded and examined by taking advantage of a questionnaire which was administered pre and post stent insertion. Results: The study population was comprised of 15 women and 10 men. The individuals' average age was 69.20 ± 11.25 years. Dysphagia mean score was lowered from a value of 4.32 ± 0.80 to 2.00 ± 1.22 (P-value<0.05). The prevalent side effects were chest pain (64%), dysphagia recurrence (40%), stent blockage (20%), stent migration (16%), GI bleeding (8%), and malposition (8%). Also, it was found out that 64% of the patients survived for 6 months. Conclusion: The results indicated that although esophageal stenting is accompanied with side effects in patients with inoperable esophageal cancer, but it is the most frequently used and the most reliable method in relieving dysphagia and improving dysphagia-related life indices.

Biofeedback efficacy to improve clinical symptoms and endoscopic signs of solitary rectal ulcer syndrome.

Solitary rectal ulcer syndrome (SRUS) is often resistant to medical and surgical treatment. This study assessed the effect of biofeedback in decreasing the symptoms and the healing of endoscopic signs in SRUS patients. Before starting the treatment, endoscopy and colorectal manometry was performed to evaluate dyssynergic defecation. Patients were followed every four weeks, and during each visit their response to treatment was evaluated regarding to manometry pattern. After at least 50% improvement in manometry parameters, recipients underwent rectosigmoidoscopy. Endoscopic response to biofeedback treatment and clinical symptoms were investigated. Duration of symptoms was 43.11±36.42 months in responder and 63.9 ± 45.74 months in non-responder group (P=0.22). There were more ulcers in non-responder group than responder group (1.50 ±0.71 versus 1.33±- 0.71 before and 1.30 ± 0.95 versus 0.67 ±0.50 after biofeedback), although the difference was not significant (P=0.604, 0.10 respectively). The most prevalent symptoms were constipation (79%), rectal bleeding (68%) and anorectal pain (53%). The most notable improvement in symptoms after biofeedback occured in abdominal pain and incomplete evacuation, and the least was seen in mucosal discharge and toilet waiting as shown in the bar chart. Endoscopic cure was observed in 4 of 10 patients of the non-responder group while 8 patients in responder group experienced endoscopic improvement. It seems that biofeedback has significant effect for pathophysiologic symptoms such as incomplete evacuation and obstructive defecation. Improvement of clinical symptoms does not mean endoscopic cure; so to demonstrate remission the patients have to go under rectosigmoidoscopy.

Liver Hydatid Cyst and Acute Cholangitis: a Case Report.

Amongst the cause of cystic hepatic disease, hydatid cyst is common in the Asia, South America, and Africa. The definitive therapy for hepatic hydatid disease is surgical resection. Rupture of the hydatid cyst into the biliary tree can lead to serious cholangitis. In this report, a 22-year-old man is presented with the signs and symptoms of obstructive jaundice and cholangitis. Ultrasonography reported dilated common bile duct (CBD) with sludge and stones, a hydatid cyst adjacent to the gall bladder and mild thickening of gallbladder wall without a stone. MRCP revealed dilated CBD with a cyst in segment fifth of liver. Due to signs and symptoms of obstructive jaundice in addition to lab data and imaging modalities, the ruptured hydatid cyst into a biliary tree was considered, and surgical intervention was performed to extract daughter vesicles from the CBD. Post intervention, signs and symptoms and cholestasis enzymes were subsided.

Findings of impedance pH-monitoring in patients with atypical gastroesophageal reflux symptoms.

AIM: This study was designed to investigate about findings of Impedance pH-monitoring in patients with atypical symptoms of GERD. BACKGROUND: The routine treatment with proton pump inhibitors is not very effective in patients with atypical symptoms of Gastro-Esophageal Reflux Disease (GERD). It may be due to non-acid reflux which cannot be monitored using common methods such as pH-metry. Therefore, in these patients combinational procedure of multi channel intraluminal impedance and pH monitoring has been suggested as a new approach. PATIENTS AND METHODS: Sixty patients with atypical symptoms of GERD underwent combined impedance pH-monitoring. pH of reflux episodes, type of material refluxant, blous cleaning time, proximal extension and symptoms association probability (SAP) was recorded for each patient. RESULTS: Globus sensation was reported as the most common atypical symptom. 95% of patients experienced weakly acid reflux. Mixed and pure gas refluxates were more frequent than pure liquid reflux. Bolus clearing time was pathologic in 36.7% of cases and proximal extension was detected in 43 patients (71.7%). Of the 46 symptomatic patients, 33.3% had a positive SAP and 43.3% had a negative SAP. CONCLUSION: The findings of current study showed that the combinational procedure of MII and pH monitoring could provide important information for resistant to treatment patients' with atypical GERD symptoms.
