[THE INCIDENCE OF PERIPARTUM HYSTERECTOMY IN FIVE CROATIAN HOSPITALS DURING A SIXTEEN-YEAR PERIOD].

Introduction: Peripartal hysterectomy (PPH) is a life saving surgical procedure that is performed when conservative measures fail to control bleeding. According to literature data there is an increase in incidence among developed countries.

Aim: To define the rate of PPH during two eight-year periods in five Croatian hospitals in respect to mode of delivery.

The effects of prior antagonist muscle vibration on performance of rapid movements.

The effects of prior vibration of the antagonist triceps muscle on the performance of rapid discrete elbow flexion movements were studied in healthy volunteers. The subjects performed 520 movements over five experimental sessions. The application of prior vibration resulted in a shift of the initial position, an undershoot of the final position in untrained subjects, and also in trained subjects if not applied during practice.

Effects of cutaneous afferent input on fatigue-induced changes in fusimotor activity of decerebrate cats.

Interaction of cutaneous and small-diameter, primarily fatigue-induced, muscle afferent inputs on fusimotor neurons has been studied in decerebrate cats. Spike discharges of fusimotor neurons to medial gastrocnemius were recorded from filaments dissected free from this muscle nerve. Non-noxious mechanical stimuli (10 Hz, 2 mm vibration) were applied to the skin area on the lateral side of the heel, innervated by sural nerve, during long-lasting (250 s) fatiguing contraction of lateral gastrocnemius and soleus muscles, elicited by electrical stimulation (40 Hz, 1.

Central changes in muscle fatigue during sustained submaximal isometric voluntary contraction as revealed by transcranial magnetic stimulation.

Changes in responses to transcranial magnetic stimulation (TMS) during submaximal isometric voluntary contraction (60% of maximal voluntary contraction (MVC) of the adductor pollicis muscle and the subsequent recovery period have been studied in healthy volunteers. TMS at twice the motor threshold was applied during the sustained contraction, as well as at rest and during short-lasting (2 s) 60% MVCs before and immediately after the sustained contraction, and at 5 min intervals during the recovery period. Both motor evoked potential (MEP) magnitude (peak and area) and silent period (SP) duration in electromyographic activity (EMG) of the adductor pollicis muscle showed a gradual decrease up to the endurance point and an increase thereafter.

Fusimotor outflow to pretibial flexors during fatiguing contractions of the triceps surae in decerebrate cats.

Changes in discharge rate of fusimotor neurones to pretibial flexor muscles were recorded during and after long-lasting fatiguing isometric and/or isotonic contractions of triceps surae in decerebrate cats. The contractions were elicited by electrical stimulation of the nerves to triceps. Fusimotor spikes were recorded from nerve filaments dissected free from the peroneal nerve.
