Evidence-based approach to dyspepsia: from Helicobacter pylori to functional disease.

Patients with dyspepsia may present with associated complaints of abdominal pain, bloating, fullness, acid reflux, and epigastric tenderness on examination. The evaluation of patients with dyspepsia includes taking a comprehensive history and performing a physical examination. Although taking a patient history has its limitations in making an accurate diagnosis, it is useful in guiding the selection of subsequent diagnostic tests. Differential diagnoses of dyspepsia are best addressed using an anatomical approach. Patients with chronic dyspepsia lasting > 1 month should be evaluated for the presence of alarm features. Alarm features mandate an upper gastrointestinal endoscopy examination, as these may be suggestive of a malignancy. In patients without alarm features, a Helicobacter pylori test-and-treat strategy is cost-effective if the prevalence of H. pylori infection is high. Tests for H. pylori infection can be divided into non-invasive and minimally invasive tests. Many different antibiotic combination therapies (eg, triple therapy, quadruple therapy, levofloxacin-based therapy, sequential therapy, concomitant therapy, and probiotics with eradication therapy) are now available for the eradication of H. pylori infection. In patients who are symptomatic without an organic pathology, functional dyspepsia and other causes of abdominal pain need to be considered. Functional dyspepsia is best managed using a multifaceted approach by establishing a good physician-patient relationship, dietary and lifestyle interventions, medical therapy, psychotherapy, and the use of psychotropic medications. This review rationalizes the current-day recommendations for the evaluation and management of patients with dyspepsia in a clinical setting.

An unusual cause of 'ptosis'.

A 29-year-old man with a history of dental restoration procedure was referred for a left Bell's palsy. At the emergency department, he complained instead of deteriorating unilateral ptosis and dysphagia. Incidentally, trismus was also noted. He was diagnosed with cephalic tetanus, which rapidly progressed to generalized tetanus. Ptosis is an unusual presenting complaint of tetanus. In this case, we attempt to explain how facial weakness, ptosis, and cephalic tetanus are all related. We also highlight the key aspects of tetanus in relation to the emergency physician.

Validation of the English version of the Asthma Quality of Life Questionnaire in a multi-ethnic Asian population.

The purpose of study was to assess the validity, reliability and acceptability of the English version of the Asthma Quality of Life Questionnaire in a multi-ethnic Asian population. The English version of the Standardized Asthma Quality of Life Questionnaire (AQLQ-S) and the Asthma Control Questionnaire (ACQ) were self-completed by 119 English-speaking Chinese, Malay and Indian asthmatic subjects, aged 17-78. Spirometric measurements, peak expiratory flow rate, current clinical symptoms and treatment requirements were documented. Reliability and responsiveness were analyzed in a subgroup of 57 patients who were reassessed 6 weeks later. The Cronbach alpha reliability coefficient for internal consistency of the AQLQ-S was 0.97 (0.96-0.98) for the overall score. The intraclass correlation coefficient (ICC) overall score was 0.97 (95% CI: 0.94-0.99) while the responsiveness index was 1.29 with strong longitudinal validity for clinical and spirometric measures of asthma severity and asthma control score (p < 0.001). The results of this study showed that the English version of the AQLQ-S is a sensitive and valid instrument for measuring health-related quality of life in asthmatic subjects from a multi-ethnic Asian population.
