Insulin-dependent diabetes: a possible viral disease.

The available information regarding the possible relevance of viruses in the pathogenesis of insulin-dependent diabetes is reviewed. Experimental studies in animals, clinical cases, histopathologic findings as well as epidemiologic and family studies provide circumstantial evidence that at least some cases of the disease are triggered by infection. Moreover, since it is widely accepted that autoimmunity plays a key role in diabetogenesis, the possible relationship between viruses and the induction of autoimmune responses to pancreatic islets is discussed. In view of recent developments in our comprehension of several chronic "idiopathic" diseases, the role of persistent viral infections and virus-induced immunopathology deserve further consideration in the etiology and pathogenesis of diabetes.

[The esophageal motor pattern and the acid exposure of the distal esophagus in patients with gastroesophageal reflux].

Low-compliance standard manometry and 24-hour ambulatory pH monitoring were performed in 42 patients with typical gastro-esophageal reflux (GER) symptoms in order to assess correlations between esophageal motility pattern and pH profile. Our results show: 1) 36% of GER patients had a normal esophageal acid exposure; 2) pH profile and manometric pattern did not differ in patients with mild esophagitis from those without esophagitis; 3) low esophageal sphincter pressure in GER patients was significantly lower than in control subjects, irrespective of acid exposure; 4) the main motility disorders in the distal esophagus of reflux patients was the increased simultaneous wave rate which seemed to affect both recumbent esophageal clearance and reflux time.

Pulmonary and extrapulmonary tuberculosis.

Pulmonary tuberculosis: primary tuberculosis, usually asymptomatic, represents the first infection and is shown by a parenchymal mostly mid-pulmonary focus and satellite lymphadenopathy. Postprimary pulmonary tuberculosis, mostly located in the upper fields may be caused by endogenous reinfection for reactivation of a hematogenous focus formed during primary infection or from exogenous reinfection. Extrapulmonary tuberculosis: it includes numerous forms mostly from hematogenous spread. Miliary tuberculosis may involve a number of organs and apparatus besides the lung. Tuberculous meningitis predominantly involves the base of the skull, the fluid is clear with hypoglycorrhachia and lymphocyte pleocytosis. Lymph node tuberculosis is generally unilateral and cervical. Tuberculous pleuritis is exudative or dry. Other forms of tuberculous serositis are pericarditis and peritonitis. Renal tuberculosis involves the medullaris and intestinal tuberculosis the ileocecum; tuberculous spondilitis (Pott's disease) involves the last dorsal vertebrae. Other forms are osteoarthritis, genital tract tuberculosis, pancreatitis, laryngitis, otitis.
