The gastroenterologist's approach to dysphagia

Factors associated with signs of aspiration in older adults: A prospective study

This was a prospective cohort design study that followed a group of older adults for up to 12 months. Two hundred and ninety-one participants with a mean age of 81.4 ± 9.1 years were recruited. Signs of aspiration were screened by the Yale Swallow Protocol. Variables investigated for risk were oromotor functions, self-perception of swallowing function, cognitive function, and medical history. Seventy participants were revisited for a follow-up aspiration screening 8 to 9 months later. Multivariate logistic regression found that male sex, need for assistance for feeding and mobility, reduced cognitive function, subjective judgement of swallowing function, and oromotor function were major variables that can be used to screen for older adults who may require referrals for swallowing assessment. Those who continue to show signs of aspiration across time exhibit a more frail profile than their counterparts who do not.

Predictors of esophageal candidiasis among patients attending endoscopy unit in a tertiary hospital, Tanzania: a retrospective cross-sectional study

Background

Esophageal candidiasis is a common disease among patients with impaired cell mediated immunity. In the current study, we report esophageal candidiasis among patients with various co-morbidities attending the endoscopic unit at the Bugando Medical Centre.

Methods

This retrospective study was conducted from June to September 2015. All data of the patients who attended the endoscopic unit between 2009 and 2014 were retrieved and analyzed.

Results

A total of 622 patients who underwent oesophagogastroduodenoscopy were analyzed. A slight majority 334/622(53.7%) of patients were female. Out of 622 patients; 35(5.6%) had esophageal candidiasis. Decrease in age (OR 1.1, 95%CI; 1.0–1.1), female sex (OR 3.8, 95%CI; 1.1–13.1), drinking alcohol (OR 17.1, 95%CI; 4.9–58.9), smoking (OR 8.3, 95%CI; 1.7–41.0), antibiotic use (OR 5.7, 95%CI; 2.0–16.4), positive HIV status (OR 10.3, 95%CI; 4.6–6.0) and presence of peptic ulcer disease (OR 13.2, 95%CI; 3.5–49.0) independently predicted esophageal candidiasis.

Conclusion

Patients with a history of drinking alcohol, smoking, use of antibiotics and those with chronic diseases such as peptic ulcers were at high risk of developing esophageal candidiasis. Further studies are needed to identify Candida spp. and their anti-fungal susceptibility for proper management of esophageal candidiasis in HIV and non-HIV individuals.

Geriatric alcoholism

BACKGROUND

The authors reviewed the clinical features, epidemiology, diagnosis, medical treatment, orofacial findings and dental treatment of geriatric patients with alcoholism.

TYPES OF STUDIES REVIEWED

The authors conducted MEDLINE searches for the period 1995 through 2004 using the terms "alcoholism," "geriatric," "pathophysiology," "treatment" and "dentistry." They selected reports published in English in peer-reviewed journals for further review.

RESULTS

Physiological changes associated with aging permit the harmful effects of drinking alcohol to arise at lower levels of consumption than in younger people. Excessive use of alcohol exacerbates the medical and emotional problems associated with aging and predisposes the person to adverse drug reactions with medications controlling these illnesses.

CLINICAL IMPLICATIONS

The incidence of dental disease in this population is extensive because of diminished salivary flow and a disinterest in performing appropriate oral hygiene techniques. Concurrent abuse of tobacco products worsens dental disease and heightens the risk of developing oral cancer. Identification of patients who abuse alcohol, a cancer-screening examination, preventive dental education, and use of saliva substitutes and anticaries agents are indicated. Clinicians must take precautions when performing surgery and when prescribing or administering analgesics, antibiotics or sedative agents that are likely to have an adverse interaction with alcohol.

Estudo comparativo da deglutição com nasofibrolaringoscopia e videodeglutograma em pacientes com acidente vascular cerebral

Os distúrbios da deglutição são bastante freqüentes nos pacientes neurológicos e naqueles com doenças ou seqüelas de cirurgia de cabeça e pescoço, sendo causa de importante morbidade e mortalidade. Apesar do videodeglutograma (VD) ser considerado o exame de escolha para a avaliação dos distúrbios da deglutição, este exame apresenta limitações em algumas situações clínicas, além de expor o doente à radiação e ao risco de aspiração do contraste. Em anos recentes, têm sido também utilizadas fibras ópticas flexíveis para avaliar os pacientes com disfagia e outras queixas relacionadas à deglutição. OBJETIVO: Análise comparativa entre os dados obtidos pela NFL e VD em relação a parâmetros estudados por ambos métodos. FORMA DE ESTUDO: Caso controle. MATERIAL E MÉTODO: Foram avaliados prospectivamente 12 pacientes com seqüela de acidente vascular cerebral isquêmico, no período de janeiro a maio de 2002, por meio do estudo dinâmico da deglutição com nasofibrolaringoscopia (NFL) e VD, sendo os resultados comparados estatisticamente. RESULTADOS: Enquanto o VD permite a análise da fase preparatória oral e oral da deglutição e o início da fase faríngea, a NFL permite estudo da sensibilidade e mobilidade faringo-laríngea, além da visualização direta do alimento. Através do teste estatístico McNemar, nenhum dos parâmetros analisados apresentou divergência estatisticamente significante (p<0,05) quando comparados os resultados na NFL e VD. CONCLUSÕES: A análise comparativa entre os dados obtidos pelo NFL e VD em relação a parâmetros avaliados por ambos métodos, em pacientes com disfagia, mostraram não haver diferenças significativas entre eles.

[Clinical, endoscopical and manometric evaluation of swallowing in patients with acquired autoimmune myasthenia gravis]

Dysphagia, or difficulty swallowing, is a common problem following myasthenia gravis (MG) and may lead to aspiration of saliva, food or liquids. We herein present 22 MG patients, with complaint of dysphagia, evaluated by phonoaudiological evaluation, nasofibrolaryngoscopical analysis and manometry of upper esophageal sphincter. The main objective was to evaluate the phases of the swallowing process and anatomical and functional aspects of oropharyngeal musculature. The age of patients varied from 19 to 74 years; being 19 female and 3 male. The main data were: (1) statistically significant relation between the phonoaudiological clinical evaluation and nasofibrolaryngoscopical one; (2) stomatognatical system disorders present in 100%; (3) swallowing and chewing disorders present in 100%, when clinically evaluated, and in 81,8% when evaluated by the nasofibrolaryngoscopy; (4) statistically significant relation between penetration/aspiration and antecedents of pneumonia; (5) stomatognatical muscles very altered, difficulty controlling the bolus, collection of food in the pharynx or larynx and presence of penetration and/or aspiration showed significant correlation with weakness of a pharyngeal muscles. These findings justify the necessity to evaluate clinically the swallowing phases in MG patients, with the main purpose to prevent both aspiration and dehidration from inadequate oral intake.

Systemic causes of dysphagia in adults

Dysphagia is associated with many systemic disorders. This article presents information that can be used to assist with developing a differential diagnosis in patients who have dyshpagia without an obvious localized cause. The essentials of the history, physical examination, endoscopy, and special tests are outlined.
