Blood levels of selected nutritional status indicators in young men from a rapidly modernizing society in Abu Dhabi, United Arab Emirates.

Some blood levels of selected indicators of nutritional status were assessed in young adult males among the rapidly modernizing bedouin society of Abu Dhabi. Blood specimens from 30 indigenous army recruits were tested for the following: packed cell volume, total serum proteins, albumin, globulins, serum transferrin, serum calcium (total and ionized), serum iron, and total folates in serum and in red blood cells. A control group consisted of 10 male expatriate laboratory personnel of similar age. Except for iron and folates, all parameters were within normal range. Although the average serum iron was normal, 13.3% of the army recruits were serum iron deficient. The mean serum folate in both groups fell within the indeterminate range with two deficient recruits. The mean red blood cell folate was in the low normal value in the local people with one-third of them in the borderline range, and two deficiencies with no pathological effects. The control group was well within the acceptable normal range of red blood cell folate and the difference between the means of both samples was significant. Inappropriate amounts of vegetables in the diet and prolonged cooking may be the cause of such folate inadequacy.

[Roentgenologically demonstrable changes in pneumoconiosis (author's transl)].

Based on the new international definition of pneumoconiosis the various types of this lesion and their roentgenological appearance are described. The lesions may arise from fibrosis-inducing dusts (silica, asbestos) and also from the deposition of dust particles especially those of high atomic weight. Pneumoconiosis in coal miners, the most common dust-induced lung disease in Germany, is reviewed in detail and the X-ray demonstration of dust in the lungs is discussed.

[The judgement of collagen metabolism by hydroxyproline in plasma and urine and plasma collagenic peptidase under different diet (author's transl)].

In 34 subjects--coal workers with pneumoconiosis, patients with collagenic diseases and healthy subjects--the daily urinary excretion of hydroxyproline (HP) and the plasma concentrations of HP and of collagenic peptidase have been measured during one week under HP-free and HP-enriched diet. It is shown that a 24-hour period of HP-free diet is necessary and sufficient before collecting urine or plasma for diet independent measurements of total or non-protein bound HP. Concentrations in plasma correlate well with the amounts excreted in urine. Collagenic peptidase is independent from the diet and well suited for assessment of the activity of the metabolism of collagene. There are no differences between healthy subjects and coal workers with pneumoconiosis.

[Relation between actual barometric pressure at sea level and alveolar and arterial pO2: correlations in 3,054 coal workers with and without pneumoconiosis (author's transl)].

The correlation between barometric pressure and arterial oxygen pressure has been investigated in 3,054 coal miners. Furthermore, the correlation between alveolar oxygen pressure and alveolar-arterial oxygen pressure difference and barometric pressure has been investigated in 1,669 coal miners. For low and for high pO2a there are significant correlations to barometric pressure, in particular for the young age groups. PO2A and AaDO2 show closer correlations to barometric pressure in the middle range of pO2a (65--84 mm Hg). This points to different regulating mechanisms. A correction with a uniform factor is not possible and, for clinical purposes, unnecessary, since the influence of changing barometric pressure on pO2a is only about 1--3 mm Hg.

[Specific hyposensitization in allergic diseases (author's transl)].

Hyposensitization with semi-depot extracts was effective in 439 of 533 patients (82.4%) with allergic manifestations. The result suggests that treatment will be most effective when (1) the patient is young, (2) the disease is located in the respiratory tract, (3) the disease has been of relatively short duration, (4) the hyposensitization extract contains only one type of allergen, (5) only a few allergens are involved, (6) treatment continues over a long period of time, (7) the final dosage is high, and (8) dosage and time schedules are carefully followed. Success does not depend on the patient's sex or the occurrence of side effects during the treatment.

[Therapy in bronchial asthma].

A division into two main groups is made: causal and symptomatic treatment. The first group includes elimination and avoidance of allergens and the specific hyposensitization according to own experiences. The second group is divided into medicamentous treatment (bronchodilatators, DNCG, corticosteroids, secretolytics, antibiotics, tranquilizers) and into a nonmedicamentous treatment like physiotherapy, climate therapy and psychotherapy.

[Diagnostic measures in bronchial asthma].

The diagnostic steps for in five groups divided forms of bronchial asthma are listed and are discussed. The diagnosis includes: 1. the anamnesis. 2. the clinical examination including X-ray, lung function tests, bronchologic inspection a.s.o., 3. special examinations for allergy including skin tests, provocation tests and pharmacodynamic tests, 4. serological-immunological methods of examination including determination of total IgE, specific IgE and several serum proteins.

Asthma↗

[Classification of bronchial asthma].

The bronchial asthma disease is divided into 5 groups: 1. bronchial asthma caused by allergy, 2. bronchial asthma caused by infection, 3. bronchial asthma caused by physicochemical irritants, 4. bronchial asthma caused by exercise, 5. combination between the groups 1--4. Etiological factors, immunologic phenomena so far as known and pathogenic mechanisms are listed for each group and discussed.
