THE PREVALENCE: The exact prevalence of deglutition disorders in the elderly is not known. It appears frequent in very old patients and in those suffering from polypathological symptoms, affecting 50% of the populations in long-term care units. THE EFFECTS OF AGING: Physiological aging alters various parameters of swallowing, however it seems that these modifications related to age have little effect on healthy subjects. However, they may increase vulnerability in those presenting with intercurrent pathologies. CONCOMITANT DISORDERS: Other than the decrease in efficient mastication and the existence of xerostomia, frequently observed contributing factors, many diseases may be responsible for dysphagia in the elderly. Neurological disorders, particularly cerebral vascular diseases, central nervous system degenerative disorders and neuro-motor diseases predominate. In the aging, muscular disorders and after effects of various diseases can set-in. Modifications in oropharyngeal anatomy generally results from cancerous lesions of the aero-digestive junction, but also, occasionally from extrinsic compression that does not necessarily reflect a neoplastic etiology. Zenker's diverticulitis represents a cause of dysphagia specific to the elderly. Problems in swallowing of iatrogenic origin are also frequent, following cervical radiotherapy or after oropharyngeal surgery, during tracheal intubation or when using feeding tubes and also during various medical treatments. UNDERRATED CONSEQUENCES: Dysphagia leads to multiple morbid after effects, primarily alteration in quality of life, dehydration, undernutrition, asphyxia and congestion and recurrent infections of the respiratory tract. The responsibility of deglutition disorders in the occurrence of these complications is difficult to assess in weak elderly subjects because of the frequent concomitance with multiple deficiencies and incapacities.

FROM AN ETIOLOGICAL POINT OF VIEW: Thoracic pain is a frequent symptom. Before confirming the oesophageal origin of the pain, a coronary disease must be excluded. Two principle causes are source of thoracic pain of oesophageal origin: gastro-oesophageal reflux disease and oesophageal motility abnormalities. THE DIAGNOSTIC APPROACH: This must include the questioning of the patient and the usual paraclinical examinations. To confirm the diagnosis, these examinations must establish a chronological relationship between the symptoms and the abnormalities. For economic reasons, following a normal gastroscopy, there is a tendency to propose an empirical proton pump inhibitor (PPI) test rather than a 24 hour pH-metry antireflux as first line. The improvement or even the disappearance of the symptoms confirms the diagnosis; long-term treatment with a double dose of PPI should therefore be envisaged. The pH-metry with search for results should be proposed to the non-responders and to patients with atypical reflux manifestations. Dysphagia and odynophagia suggest an oesophageal motility disorder that basal manometry should confirm. A chronological relationship is rarely revealed, but the sensitivity of the pH-meter can be enhanced by provocation tests. REGARDING TREATMENT: Other than achalasia, treatment of the other spastic-like motor disorders is not well codified. Diltiazem is efficient. Some patients exhibit a hyperalgic oesophagus. The physiopathological mechanisms are still theoretical. Low dose tricyclic antidepressors and psychological management are useful.

THE INFLAMMATORY MYOPATHIES INCLUDE THREE DISTINCT ENTITIES: polymyositis (PM), dermatomyositis (DM), and inclusion body myositis (IBM). A T-cell-mediated cytotoxic process in PM and IBM and a complement-mediated microangiopathy in DM are the hallmarks of the underlying autoimmune processes. The most consistent therapeutic problem remains the distinction of PM from the difficult-to-treat mimics such as s-IBM, necrotizing myopathies and inflammatory dystrophies. This review provides a step-by-step approach to the treatment of inflammatory myopathies, highlights the common pitfalls and mistakes in therapy, and identifies the emerging new therapies. In uncontrolled studies, PM and DM respond to prednisone to some degree and for some period of time, while a combination with one immu-nosuppressive drug (azathioprine, cyclosporine, mycophenolate, methotrexate) offers additional benefit or steroid-sparing effect. In contrast, IBM is resistant to most of these therapies, most of the time. Controlled studies have shown that IVIg is effective and safe for the treatment of DM, where is used as a second, and at times first, line therapy. IVIg seems to be also effective in the majority of patients with PM based on uncontrolled series, but it offers transient help to a small number of patients with IBM especially those with dysphagia. Bona fide patients with PM and DM who become resistant to the aforementioned therapies, may respond to rituximab, tacrolimus or rarely to an tumor necrosis factor alpha inhibitor. For IBM patients, experience with alemtuzumab, a T-cell-depleting monoclonal antibody, is encouraging.

THE GASTROINTESTINAL (GI) TRACT IS A MAJOR SITE OF DISEASE IN HIV INFECTION: almost half of HIV-infected patients present with GI symptoms, and almost all patients develop GI complications. GI symptoms such as anorexia, weight loss, dysphagia, odynophagia, abdominal pain, and diarrhea are frequent and usually nonspecific among these patients. Endoscopy is the diagnostic test of choice for most HIV-associated GI diseases, as endoscopic and histopathologic evaluation can render diagnoses in patients with non-specific symptoms. In the past three decades, studies have elucidated a variety of HIV-associated inflammatory, infectious, and neoplastic GI diseases, often with specific predilection for various sites. HIV-associated esophageal disease, for example, commonly includes candidiasis, cytomegalovirus (CMV) and herpes simplex virus (HSV) infection, Kaposi's sarcoma (KS), and idiopathic ulceration. Gastric disease, though less common than esophageal disease, frequently involves CMV, Mycobacterium avium-intracellulare (MAI), and neoplasia (KS, lymphoma). Small bowel biopsies and intestinal aspirates from HIV-infected patients often show HIV enteropathy, MAI, protozoa (Giardia, Isospora, Cryptosporidia, amebae, Microsporidia), and helminths (Strongyloides stercoralis). Colorectal biopsies demonstrate viral (CMV, HSV), bacterial (Clostridia, Salmonella, Shigella, Campylobacter), fungal (cryptococcosis, histoplasmosis), and neoplastic (KS, lymphoma) processes. Herein, we review HIV-associated GI pathology, with emphasis on common endoscopic biopsy diagnoses.

PRESBYPHAGIA: THE INFLUENCE OF PRIMARY AGING ON SWALLOWING FUNCTION: Elderly often get confronted with swallowing difficulties. It is important to differentiate between presbyphagia, which describes the influence of primary aging on swallow function and dysphagia, which is a pathological swallowing disorder caused by age related diseases and their treatment. In this literature overview the focus is on presbyphagia. The influence of primary aging on the oropharyngeal swallowing function and on other body functions that are indirectly related to swallowing will be discussed. From the literature we learn that in primary aging a number of functions stay preserved, a number of functions deteriorate, and some compensatory mechanisms are evident. The swallow safety as such however, stays preserved. To conclude with we discuss some clinical implications concerning both the detection of swallowing disorders in the elderly and the establishment of preventive action for the healthy elderly.

Double aortic arch (DAA) is a rare congenital anomaly of the heart and aorta in which a vascular ring that surrounds the trachea and esophagus is formed. In most patients, respiratory distress and dysphagia develop in childhood, and asymptomatic adult patients are rarely known. Herein, we describe a patient with lung cancer and DAA. A 66-year-old man who had DAA underwent video-assisted thoracoscopic right upper lobectomy and mediastinal lymph node dissection for primary lung cancer. Lymph node dissection of the right upper mediastinum revealed that the right recurrent laryngeal nerve branched from the right vagus nerve just beneath the right aortic arch. Additionally, the right aortic arch narrowed the space surrounding the trachea, superior vena cava, and arch of the azygos vein, impeding the stapling of the truncus anterior artery and right upper lobe pulmonary vein with the video-assisted thoracoscopic approach. KEY POINTS: SIGNIFICANT FINDINGS OF THE STUDY: In double aortic arch, the recurrent laryngeal nerve branches from the vagus nerve just beneath the ipsilateral aortic arch. The right aortic arch narrows the space surrounding the trachea, superior vena cava, and arch of the azygos vein. WHAT THIS STUDY ADDS: The anatomy of a double aortic arch impedes mediastinal lymph node dissection on the ventral side of the trachea. Handling autosuture devices for stapling pulmonary arteries and veins is also difficult.
