[Injuries to the diaphragm (author's transl)]. / Zwerchfellverletzungen.

A traumatic rupture of the diaphragm is nearly always accompanied by injuries to the intrathoracic and abdominal structures. As the symptoms arising from these injured organs generally predominate, the presence of a ruptured diaphragm is apt to remain unrecognized or to be diagnosed at a very late stage. If the diagnosis is made immediately after the accident surgical repair should follow promptly; if the rupture is of long standing (traumatic hernia) surgery should preferably be performed during a symptom-free interval. An analysis of the case material showed that the left diaphragm was more often involved than the right one, an observation that tallies with the published reports. The transthoracic approach provides a clearer view of the operating area and was, therefore, chosen. The post-operative results were satisfactory; mortality rate was nil.

Investigations were carried out using RPHA on 5299 blood serums, originating from 235 hen flocks vaccinated in four ways: Flox and orally with the vaccine strain La Sotta, intramusculary with Komarov's vaccine strain and by aerosol using the strains La Sotta and Komarov. Two hundred and eleven blood serums originating from 12 flocks, in which fowl pest was detected, were also investigated. Postinfection titer dynamics was followed in three flocks containing 20000 birds. It was established that aerosol vaccination results in highest mean geometrical titers--log2 6.3 on the average; intramuscular vaccination--in log2 5.9, oral vaccination--in log2 5.3, and Flox vaccination--in log2 4.7 on the average. The maximal value of the vaccine titers did not surpass log210, while post infection titers were of higher order and reached up to log214, which is of diagnostic value. Postinfection titers of higher than log210 value were preserved up to 5 months from the beginning of the disease, a fact of retrospective diagnostic value.
