Prevalence of Helicobacter pylori infection and chronic dyspeptic symptoms among immigrants from developing countries and people born in industrialized countries.

The relationship between Helicobacter pylori infection and chronic dyspepsia is controversial. To determine the effect of H. pylori infection on dyspeptic symptoms, we compared the prevalence of H. pylori infection in immigrants from developing countries and people born in industrialized countries. Upper abdominal symptoms were assessed by a questionnaire and H. pylori infection was determined with a 13C-urea breath test and serology. H. pylori infection was found in 63% of subjects from developing countries and 11% of subjects from industrialized countries. There was no difference in the prevalence of dyspeptic symptoms between the 2 groups. The lack of difference in chronic dyspeptic symptoms between the groups, despite a major difference in the H. pylori prevalence, suggests that H. pylori infection is not a major contributor to chronic dyspepsia.

[Massive pleural effusion in liver cirrhosis without ascites].

We present two patients with masive pleural effusion, asociated to cirrhosis. There was no clinical evidence of ascites, and in the first case it didn't even show up in the CT scanning. Al other posible causes were discarded and the therapeutic response was analysed. We evaluated the pathophysiologic mechanisms of the syndrome and we suggest the pneumoperitoneum as a diagnostic procedure which is easy to apply and carries low costs.

[Esophageal sensitivity. Projection of esophageal pain induced by balloon distension].

UNLABELLED: The esophagus is source of several kinds of painful sensibility. Esophageal sensoriality follows the general visceral sensibility laws with some individual differences. We have investigated the areas of pain projection induced by a progressive balloon distension in 2 cm scales from 38 to 22 cm. of the dental row. It was registered the number of painful responses in everyone of the 13 frontal zones an 10 dorsal zones in which the chest was divided. Epigastrium and the base of neck were included. It was considered the first patient's symptom or until a maximum of 15 ml. of air (diameter = 3.2 cm.) 101 patients were examined. 1153 responses in the all 9 stimulated levels were obtained. 93.8% were in frontal zones, and 82.4% of them in median areas (from epigastrium to neck). There were not differences between both sexes. The inferior esophagus was significantly less sensible than the superior esophagus. The number of projections to the superior chest was proportionally larger. There were individual patterns which could be usefull in a particular patient. CONCLUSIONS: a) the esophagus is not equally sensible in its whole extension; b) the metameric projection is multiple and predominates in frontal areas; c) the existence of "trigger zones" obligate to examine the whole extension of the esophagus when intraesophageal distension of a balloon is used as a diagnostic test.

Selected measures of ankle dorsiflexion range of motion: differences and intercorrelations.

The purpose of this investigation was to describe and compare ankle dorsiflexion range of motion (ADROM) measurements obtained using the heel, fifth metatarsal, and plantar surface of foot as distal surface landmarks while the ankle was dorsiflexed under three conditions. The conditions were: 1) passive ankle dorsiflexion with force adequate to encounter notable tension in the plantar flexor muscles, 2) passive ankle dorsiflexion with a maximal force, and 3) as in number 2 but actively assisted by the subject. Thirty-six women had their ankles dorsiflexed three times under each of the three conditions. Slide photographs were taken of the procedure. The photographs were projected and ADROM measured using the three distal landmarks. Analysis of variance demonstrated that ADROM measurements were significantly different (p less than 0.001) under the three conditions of measurement and when the different landmarks were used. The majority (83.3%) of the ADROM measurements were correlated significantly (P less than .01) with one another regardless of the condition or landmark of measurement. Clinicians should be aware that measurements of ADROM will differ depending on the conditions of measurement and the landmarks used. Despite the differences, measurements obtained using various combinations of conditions and landmarks will provide an indication of ADROM.

Pathomechanics of structural foot deformities.

This article presents the most common structural foot deformities encountered in clinical practice. The deformities are defined, and the expected compensations at the subtalar joint (STJ) are described. The theoretical consequences of the STJ compensations on proximal and distal tissues are presented. A biomechanical rationale for certain tissue disorders is described. The possible effects of abnormal STJ compensation on osseous development are briefly discussed.

Evaluation of functional ankle dorsiflexion using subtalar neutral position. A clinical report.

This article presents the use of a specific technique when measuring ankle joint dorsiflexion for the purpose of determining the presence or absence of sufficient motion for ambulation. The importance of locating and maintaining the subtalar joint in the neutral position when applying either measuring or stretching techniques is emphasized. A brief discussion of selected compensatory mechanisms is presented to alert clinicians to symptoms that occur in the lower extremity and that may result from insufficient ankle dorsiflexion.
