[Selective IgA defect. Clinical importance for stomatology]. / Selektiver IgA-Defekt. Klinische Bedeutung in der Stomatologie.

The clinical picture of 6 women suffering from selective IgA immunodeficiency were studied in a 2-13 years lasting period of immunological outdoor patients care. Despite of respiratory infections, otitis media, sinusitis, aphtosis and exogenous allergy the first detection of IgA deficiency was delayed til adulthood (mean age 42 years). A case of a 22 years old women with complicated fistula after molar tooth extraction showed the problems of dentistry in such diagnosis. No significant deviation concerning periodontitis and caries has been demonstrated in all patients. However, the rate of IgA deficiency demands basic knowledge about diagnosis, prevention of local and systemic complications in this disease by all practising dentists.

[Problems of bite injuries in the maxillo-facial region]. / Zur Problematik von Bissverletzungen in der Kiefer-Gesichts-Region.

Bite injuries by animals in the maxillo-facial-region require special managements of the treating physician or dentist. In the foreground stands the prophylaxis of the rabies. According to the lawful definitions the patient has to be transferred as quick as possible to the next department for rabies and inoculation. The local wound of bite must be treated with rabies-virucid medicaments. Because of aesthetic and functional reasons the primary plastic operation should be done even in cases of extensive wounds and defects in the facial region. By means of 19 cases these demands are based.

[Report on experiences of one year at the Gondar College of Medical Sciences in Ethiopia. 4. Influence of psychosocial factors on the development of orofacial function troubles]. / Erfahrungsbericht uber einen einjährigen Einsatz am Gondar College of Medical Sciences in Athiopien. 4. Mitteilung: Zum Einfluss psychosozialer Faktoren auf die Entstehung orofazialer Funktionsstörungen.

Functional disturbances of the orofacial system are permanent increasing in the European countries. These are so called psychosomatic diseases which you can find very often in patients with psychic evident personality profile. For the objective evaluation of the structure of personality are described various methods in the literature. 65 Ethiopian patients from the Gondar-region who showed parafunctional abrasions-facettes on the teeth are investigated by means of the Beck-Inventory and the Self-Control-Schedule of Rosenbaum. The influence and importance of psychosocial factors for the evocation of myoarthropathies could been demonstrated.

[Report on experiences with a one-year action at the Gondar College of Medical Sciences in Ethiopia. 3. Influence of diabetes mellitus on the teeth supporting apparatus]. / Erfahrungsbericht über einen einjährigen Einsatz am Gondar College of Medical Sciences in Athiopien. 3. Mitteilung: Zum Einfluss des Diabetes mellitus auf den Zahnhalteapparat.

Systemic diseases--like diabetes mellitus--are able to injure the local and common resistance of an organism. Therefore we must expect a more intensive and severer progress of gingivitis and periodontitis in diabetic patients in comparison with a non-diabetic control-group. On the Gondar College of Medical Sciences in Northwest-Ethiopia are investigated 77 Insulin-obliged diabetics and 312 persons for control by means of the plaque-Index, the Oral-Hygiene-Index simplified. The DMF/T-Index and the Gingivitis-respectively Periodontal-Disease-Index for evaluation of the oral health situation. The comparison shows that the diabetic group has a moderate higher Plaque-pictures of gingivitis or periodontitis. This confirms our opinion that the diabetes mellitus is a risk-factor for the development of periodontal diseases. Therefore patients with diabetes mellitus should perform a very intensive care for mouth-hygiene.

[Report of experience during 1-year at the Gondar College of Medical Sciences in Ethiopia. 2. Frequency of caries and periodontitis in Ethiopia]. / Erfahrungsbericht über einen einjährigen Einsatz am Gondar College of Medical Sciences in Athiopien. 2. Mitteilung: Zur Häufigkeit von Karies und Periodontitis in Athiopien.

On the basis of a clinical epidemiological study of 312 patients are made biostatistical investigations about prevalence and Severity of dental caries and marginal periodontitis. The situation of oral hygiene is evaluated by means of the PI of Løe and Silness and the OHI-S of Greene and Vermillion. The DMF/T-Index is used for the evaluation of the set of teeth and the GI of Løe and Silness like the PDI of Ramfjord for the evaluation of the periodontal state. It is shown that caries and marginal periodontitis are more seldom and of less severity in comparison with the situation in the population of industrialized countries. Causitive seems to be possible besides special habits the smaller consumption of sugar. With the increasing socio-economic standard a changing of the situation in the direction of industrialized countries is visible.

[The use of sulfonamide containing drug combinations in pyogenic processes of the maxillofacial region]. / Zum Einsatz von sulfonamidhaltigen Kombinationspräparaten bei pyogenen Prozessen im Kiefer-Gesichts-Bereich.

Compound preparations containing trimethoprim and sulphonamide have been available in the pharmacies of the GDR since 1974. These are the preparations Berlocombin 200 (trimethoprim + sulphamerazine) and Sulprim 120 and 480 (trimethoprim + sulphamethoxazole) which are of great efficacy and have a broad spectrum of action. The mode of action, side-effects, dosage, commercial dosage forms and contraindications are described. Clinical tests have shown that a success-rate of 80.3% may be expected from treating pyogenic processes. Compound preparations of this kind might fill, at least in part, the gap caused by the increasing ineffectiveness of penicillin which is due to bacterial resistance.

[Sialolithiasis]. / Ein Beitrag zur Sialolithiasis.

Affections of the major salivary glands are relatively rare in stomatology; but according to the indications of several authors, the proportion of sialolithiasis to the total amount of affections of the salivary glands (ranging from 20.5 to 55.5%) is great. The concretions are, as a rule, located in the duct system of the submandibular gland where they may reach, circumstances permitting, considerable sizes. The author's own investigations evidence that these calculi have a partly regular, partly irregular shell-like structure around a non-calcified centre. Chemical analysis by means of X-ray diffractometry revealed hydroxyapatite varying in the degree of cristallinity as the major component. Precursors in the form of octacalcium phosphate and dicalcium phosphate dihydrate have been disclosed. Salivary calculi must be removed (most frequently by surgical intervention) to avoid secondary diseases of the duct system of the respective gland.

[Results of an analysis of waiting time at a maxillofacial surgery outpatient department of a university hospital]. / Ergebnisse einer Wartezeitanalyse in der Kieferchirurgischen Ambulanz einer Universitätsklinik.

Waiting periods in public health institutions not only stress the patients and the personnel, but they are also attended by considerable economic disadvantages. For this reason, the waiting periods of patients of a maxillofacial outpatient department in the various examination and treatment stations were analyzed with the help of accompanying leaflets. According to the results obtained, the sequence of examinations and treatments was verified and reorganized with regard to the three main processes: research, medical care, and education and training. The control by a second analysis evidenced a reduction of the total waiting period from 46.0 to 36.9 minutes per patient. Further possibilities of reducing the waiting periods are indicated, and reasons are given for the necessity for scientific work organization in public health institutions.
