Intra-Abdominal Spilled Gallstones Mimicking Malignancy: A Case Report and a Literature Review.

The incidence of gallstone spillage and gallbladder perforation has increased as a result of the rising use of laparoscopic cholecystectomy. The presence of gallstones in the abdomen may lead to adhesions, inflammation, infection, and obstruction of biliary ducts. Since different etiologies can occur with spillage of gallstones, variation in presentation is expected. We report a case of a laparoscopic cholecystectomy complication after four years of surgery. The patient's clinical presentation mimicked malignancy.

Health and Safety in Temporary Work Zone Road Construction Project in Saudi Arabia: Risks and Solutions.

Road project sites are dangerous and crash-prone, with many hazards that can cause injuries and can result in the deaths of road users or site-workers. Work zones for road construction or maintenance can potentially contribute to increasing these crashes. Many studies have addressed this issue; however, there is a lack of similar studies in Saudi Arabia. Therefore, this study contributes to developing safety practices for road work zones in Saudi Arabia by identifying, analyzing, and controlling the main risk factors. A survey approach was used to identify risk factors and potential countermeasures from road users' and civil engineering experts' perceptions. The main findings showed that most participants believed that the presence of work zones on the road might increase the probability of crash occurrence and that the highest risk factor that could cause a crash in a work zone is related to driver behavior. Both groups agreed that strict action against contractors or consultants who have safety violations would enhance road safety in work zones. Considering the findings of this study, decision-makers should take strong action to implement and improve road safety practices.

Efficacy of a bismuth-based quadruple therapy regimen for Helicobacter pylori eradication in Saudi Arabia.

BACKGROUND/AIM: The treatment efficacy of Helicobacter pylori (H. pylori) has been decreasing over time due to resistance to multiple antimicrobial therapies. The most effective treatment regimen for Saudi Arabian patients infected with H. pylori is still unknown. We aimed to study the eradication rate of 10 days of quadruple therapy; bismuth subcitrate potassium 140 mg, metronidazole 125 mg, and tetracycline 125 mg for H. pylori infection in a Saudi population. PATIENTS AND METHODS: This was a prospective, open-label, non-randomized controlled trial. Patients with H. pylori infection were diagnosed by upper gastrointestinal (GI) endoscopy and rapid urease test (RUT) or histology. Patients who tested positive were recruited. Eligible patients were prescribed a 10-day course of quadruple therapy and received three capsules 4 times daily for 10 days along with omeprazole 20 mg twice daily. H. pylori was considered eradicated if the urea breath test (UBT) was negative after 6 weeks of completing the treatment. RESULTS: Ninety-two patients with H. pylori infection were recruited. Three patients withdrew from the trial and another seven patients lost follow-up. We analyzed 82 patient's data as per-protocol analysis, of whom 66 (80%) were naive to H. pylori treatment. Four patients had failed previous treatment with the sequential regimen and 12 patients had treatment with clarithromycin-based triple therapy. The post-treatment UBT for H. pylori infection was negative by per-protocol analysis in 72/82 patients (87.8%), and 72/92 (78.3%) by intention-to-treat analysis. There was no correlation between previous treatment failure and treatment response to the bismuth-based quadruple therapy (P value = 0.28). CONCLUSIONS: Treatment with a bismuth-based quadruple therapy was effective in eradicating H. pylori infection in 78.3% of Saudi patients with an ITT analysis and in 87.8% as per-protocol analysis.

Levodopa-Carbidopa Intestinal Gel Infusion Therapy in Advanced Parkinson's Disease: Single Middle Eastern Center Experience.

BACKGROUND: Levodopa therapy in Parkinson's disease (PD) is often associated with disabling motor and non-motor complications in patients with advanced disease due to the variable absorption of levodopa because of an irregular or erratic emptying of the gastric content. METHODS: Prospective single movement disorder center study using pre-set selection criteria, unified PD scale (UPDRS III), non-motor symptoms scale (NMSS), and PD questionnaire-8 (PDQ-8) to evaluate the efficacy, safety, and long-term treatment outcomes using levodopa-carbidopa intestinal gel (LCIG) infusion in patients with advanced PD, who were followed up every 6 months. RESULTS: Twenty patients were recruited over a period of 6 years. Disease duration prior to LCIG infusion ranged from 5 to 18 years (mean 11.4 ± 4.2). The mean follow-up time on LCIG therapy was 48.5 ± 23.2 months (range 11-83 months). Mean 'off' time, UPDRS III, NMSS, and PDQ-8 improvement were statistically significant. Two patients dropped out and 66.7% of patients required tube replacement. CONCLUSION: LCIG infusion monotherapy demonstrated significant improvement in reducing the 'off' time, reducing levodopa-induced dyskinesia, and improving non-motor symptoms and quality of life. This therapy is recommended for patients in whom motor fluctuations are inadequately treated with traditional oral PD therapy.

Tenofovir in the treatment of naïve and refractory chronic Hepatitis B: A single center experience in Saudi Arabia.

BACKGROUND/AIMS: Tenofovir disoproxil fumarate (TDF) is a nucleotide analog used in the treatment of chronic hepatitis B (CHB) infection. This study evaluated the efficacy of TDF in achieving undetectable HBV DNA after 48 weeks of treatment in a Saudi cohort of CHB patients. PATIENTS AND METHODS: This retrospective study included patients treated at a tertiary care center in Saudi Arabia from January 2009 to December 2012. Of the 68 eligible patients, 51 were treatment naïve and 17 were treatment-refractory. Twenty-three patients tested positive for HBeAg. The remaining 45 patients were HBeAg-negative. RESULTS: The mean HBV DNA viral load decreased from 95 million IU/mL at baseline to 263 IU/mL after 48 weeks of treatment (P < 0.001). Overall, 62% of patients achieved a complete virological response (CVR) and 37% a partial virological response (PVR). Respective CVR and PVR rates according to subgroup were: HBeAg-positive (21.7% and 78.3%) and HBeAg-negative (84.4% and 15.6%). At 48 weeks, HBV DNA was undetectable in 66.7% of treatment-naÏve and 53% of treatment-refractory patients (P = 0.3). Seroconversion occurred in 13 (57%) of HBeAg-positive patients. Two (3%) of the HBeAg-negative patients lost HBsAg at follow up. Mean alanine aminotransferase decreased significantly from 134 U/L before treatment to 37 U/L at 48 weeks (P < 0.001). Significant adverse events were not encountered during the study period. CONCLUSION: Forty-eight weeks of treatment with TDF reduced HBV DNA to undetectable levels in more than half of our patients regardless of whether they were treatment-naïve or refractory. HBeAg-negative (vs positive) patients experienced a better response rate.

Functional soft palate reconstruction: a comprehensive surgical approach.

BACKGROUND: Dysfunction of the soft palate is devastating to the patient's quality of life, resulting in unintelligible speech and poor swallowing. Reconstruction of the soft palate is complex because the dynamic fibromuscular structure cannot be duplicated. The efficacy of soft palate reconstruction has therefore been called into question. The purpose of this article is: (1) to describe our comprehensive surgical paradigm for soft palate reconstruction, (2) to provide details of the surgical techniques used, and (3) to report on patient functional outcomes. METHODS: Fifty-two patients spanning 3 different size-based categories of soft palate reconstruction were included in the final analysis. Using videofluoroscopic studies of swallowing, the presence of nasopharyngeal reflux and any instance of aspiration of a bolus into the airway was noted. In addition, a simple diet survey was completed, and the use of a g-tube was noted. RESULTS: The results revealed that our protocol for soft palate reconstruction provided the majority of our patients with separation of the oropharynx and nasopharynx, while maintaining nasal patency. Restoration of swallowing function was timely, with 91% of the patients returning to an oral diet at the early postoperative visit and only 14% of patients demonstrating mild nasopharyngeal reflux. CONCLUSION: We have developed a comprehensive reconstructive protocol that provides patients with separation of the oropharynx and nasopharynx, while maintaining nasal patency. Restoration of function is timely, with reestablishment of normal intelligibility and resonance of speech as well as safe and efficient swallowing function.
