The widely unknown hypothenar hammer syndrome (HHS) is caused by chronic mechanical trauma; in these cases the hypothenar is used as a tool. This may cause intimal lesions of the ulnar artery usually near the hamate bone resulting in thrombosis or aneurysms. ⋯ Positive evidence of causal relationship between occupational exposure and appearance of HHS has to be acknowledged as occupational disease.

Non-invasive mechanical ventilation (NIPPV) is an accepted choice of treatment in patients with chronic pulmonary disease and/or acute respiratory failure. Recently NIPPV was also proposed in the postoperative weaning period. ⋯ Non-invasive ventilation after lung transplantation enables earlier extubation and prevents weaning failure.

Non-invasive mechanical ventilation is used with success for ventilatory failure due to derangements of the respiratory pump. Efficacy in pulmonary diseases is controversial. Still non-invasive intermittent ventilation is reported as a mean of bridging the period till lung transplantation can be performed. ⋯ Non-invasive intermittent ventilation was seen as successful in 14 patients. Of these 4 are transplanted after up to 2 years, 4 are still waiting, 2 have not yet entered a lung transplantation program, 1 continued non-invasive intermittent ventilation after refusal to be enlisted, 3 meanwhile died. In the group of non-successful non-invasive intermittent ventilation 2 patients were transplanted after a short waiting period. All remaining 4 patients died. It seems that non-invasive intermittent ventilation may be helpful in prolonging the period of survival while waiting for lung transplantation.
