We prospectively evaluated the initial presenting symptoms in 261 patients with Zollinger-Ellison syndrome (ZES) over a 25-year period. Twenty-two percent of the patients had multiple endocrine neoplasia-type 1 (MEN-1) with ZES. Mean age at onset was 41.1 +/- 0.7 years, with MEN-1 patients presenting at a younger age than those with sporadic ZES (p < 0.0001). ⋯ Gastrinoma extent and location have minimal effects on the clinical presentation. Overall, neither the introduction of successful antisecretory therapy nor widespread publication about ZES, attempting to increase awareness, has shortened the delay in diagnosis or reduced the incidence of patients presenting with peptic complications. The introduction of successful antisecretory therapy, however, has dramatically decreased the rate of surgery in controlling the acid secretion and likely led to patients presenting with less severe symptoms and fewer complications.

We report an illustrative case of advanced "hut lung," or domestically acquired particulate lung disease (DAPLD), in a recently emigrated nonsmoking Bangladeshi woman with a history of 171 hour-years of exposure to biomass smoke. She presented with symptoms of chronic cough, dyspnea, and early parenchymal lung disease. High-resolution computed tomography (CT) of the chest demonstrated numerous 2- to 3-mm nodules, sparing the pleural surface. ⋯ While a detailed environmental history is essential for making the diagnosis in most individuals, for patients with advanced DAPLD, invasive modalities such as bronchoscopy with transbronchial biopsy and examination of bronchoalveolar lavage fluid help differentiate it from other diseases. Recognition of this syndrome and removal of the patient from the environment is the only treatment. The development of well-controlled interventional trials and the commitment of sufficient resources to educate local populaces and develop alternative fuel sources, stove designs, and ventilation are essential toward reducing the magnitude of DAPLD.

Giant cell (temporal) arteritis (GCA) is the most common systemic vasculitis in Western countries. It involves large and medium-sized vessels with predisposition to the cranial arteries in the elderly. Cranial ischemic complications, in particular permanent visual loss, constitute the most feared aspects of this vasculitis. ⋯ The present study supports the claim that ocular ischemic complications are still frequent in biopsy-proven GCA patients from southern Europe. The presence of other ischemic complications constitutes an alarm for the development of irreversible blindness. In contrast, a higher inflammatory response may be a protective factor against the development of cranial ischemic events.

Review Case Reports
Central nervous system aspergillosis in patients with human immunodeficiency virus infection. Report of 6 cases and review.
Central nervous system (CNS) aspergillosis is a relatively uncommon complication of human immunodeficiency virus (HIV) infection. We describe 6 patients with the acquired immunodeficiency syndrome (AIDS) who developed CNS aspergillosis, and we review a total of 33 cases of CNS aspergillosis among HIV-infected individuals that were diagnosed by histology and/or culture. All patients were diagnosed with advanced HIV infection. ⋯ CNS aspergillosis should be included in the differential diagnosis of HIV-infected patients who present with nonspecific neurologic symptoms and signs. If we take into account the much higher prevalence of invasive aspergillosis of the lungs, the findings in the present report suggest that CNS aspergillosis in HIV-infected individuals occurs more often as a result of direct extension from the sinuses, orbits, and ears than through hematogenous spread from the lungs. Physicians should be aware that the CNS might be the only site of Aspergillus involvement and include CNS aspergillosis in the differential diagnosis of HIV-infected patients presenting with focal neurologic signs and symptoms, especially when the head CT reveals hypodense lesions.
