[Use of high frequency ventilation in patients with respiratory insufficiency].
High frequency ventilation is very common today for treatment of patients with respiratory insufficiency in the ICU as well as intraoperatively. This special kind of artificial ventilation is suitable for patients with decreased lung volume and reduced thoracic and lung compliance. Favourable results in the treatment of ARDS are described. ⋯ The resulting lower peak and mean airway pressure is advantageous. Therefore the barotrauma of the lung is reduced during high frequency ventilation. For these reasons high frequency ventilation is an alternative method for ventilation of patients with so called "stiff lungs" with reduced thoracic and lung compliance.

In general aluminium dust induced fibrosis of the lungs occurs very rarely. Based on an own observation of a clinical case the problem of clinical and pathological diagnosis is discussed. Aluminium was detected in the lung by histological, chemical and atomic absorption spectroscopy procedures. Anamnesis, epicrisis, clinical symptomatology and the result of autopsy permit to diagnose aluminium dust induced fibrosis of the lung, taking into consideration the detection of aluminium dust by chemical and atomic absorption spectroscopy methods.

[Animal experiment studies of high frequency jet ventilation with a newly developed pneumatically controlled respirator].
The effects of high frequency jet ventilation (HFJV) were investigated in 12 mongrel dogs with normal lungs. A newly developed HFJV device with purely pneumatic regulation was used. ⋯ Accordingly, HFJV is possible with the tested device under clinical conditions in the frequency range between 80 and 300/min, with a breathing time ratio of 1:21 to 1:1 and a driving pressure up to 0.4 MPa with an oxygen concentration of FiO2 = 0.21 to 1.0. Before clinical use, however, investigations on the damaged lung of the dog are necessary.

The immunotherapy with purified bee and wasp venom is indicated for patients with severe general reactions after insect stings, positive prick test and positive RAST. One hundred seventy four persons were treated for three years with bee venom (SSW Dresden) and 34 patients with wasp venom (Reless). Challenge by a stinging bee after treatment proved in 90 per cent complete protection. ⋯ Therefore rush desensitization should be performed in indoor patients till a top dose of 100 micrograms/ml is reached. Booster injections can be given to outdoor patients. All individuals with systemic reactions after insect stings have to get an emergency treatment kit and must be familiar with its application.
