Eight male patients with amyloid polyneuropathy, seven of whom had symptoms of dysfunction of the urinary bladder, were studied by cystometry and micturition analysis and compared with eight male controls. Most of the patients with amyloidosis had an increased bladder capacity. The need to micturate was reduced, and urine retention was common. In most of them detrusor function could not be demonstrated. The maximal flow rate was usually diminished and the resistance to flow elevated. In some of the patients there was increased rigidity of the bladder wall.

Grip strength of the human hand--measurements on normal subjects with a new hand strength analysis system (Hastras).

This study describes a method of acquiring data from healthy and non-injured men that can be used as reference data when measuring the grip strength of the human hand using newly developed, PC-based hand strength analysis equipment--'Hastras'. Hastras can be used for continuous measurement and recording of force when the subject grips a sensor with maximum power. Computerized analysis of the force signal gives information about maximum force, fatigue, area and rise (force/s). The statistical analysis of the measurements on 81 subjects are consistent with earlier published data from other hand strength equipment. It is concluded that Hastras gives easy processing and storage of data, and also a detailed analysis of grip function.

Pre- and postoperative respiratory muscle strength in primary hyperparathyroidism.

Muscle function in ten hyperparathyroid patients and six patients with benign thyroid disease was assessed by measuring maximal expiratory (Pe max) and inspiratory (Pi max) pressures before and 6-12 months after neck surgery. Pe max was improved in all the hyperparathyroid patients postoperatively (p less than 0.002), while the median value of Pi max was unchanged. In the control (thyroid) group there was no significant postoperative change in either Pe max or Pi max. It is concluded that normalization of hypercalcemia improves respiratory muscular capacity, which can be quantified by measuring maximal expiratory pressure.
