Pituitary function before and after transsphenoidal adenomectomy in patients with Cushing's disease.

Over the past 4 years 11 patients with Cushing's disease have been operated on by a transsphenoidal microsurgical technique. All patients had small intrahypophyseal adenomas found at operation. Eight of the 11 patients had a remission of the disease on the basis of clinical evaluation and hormonal studies. The endocrinological results revealed a transient state of hypocorticism in all successfully treated patients. Within 6-8 months after operation recovery of hypothalamic-pituitary-adrenal function and other tropin function took place. These findings, together with the absence of recurrence up to now, further confirm the efficacy of transsphenoidal surgery in the management of patients with Cushing's disease.

Traumatic brain lacerations in children: surgical results and follow-up.

75 children ranging in age from 3 months to 14 years, operated on for post-traumatic cerebral lacerations, within an 18-year period, have been analyzed. These represent 2.1% of 3,460 children sustaining head injury and hospitalized during this same period. Total mortality was 16%. The cases were divided into 2 groups: (A) cerebral lacerations underlying a depressed fracture (coup lesion) -- 68 cases. In 42 cases the lacerations were focal without edema and/or intracerebral hematoma. 1 child died and 41 survived. In 26 cases the laceration was diffuse and accompanied by cerebral edema and/or intracerebral hematoma. 6 children died and 20 survived. (B) Brain lacerations following a contrecoup lesion -- 7 cases, 5 of these children died and 2 survived. The follow-up of the surviving patients in the above two groups has been discussed.

[Effect of metoprolol on the exercise tolerance in patients with stable angina pectoris (author's transl)].

The effect on the exercise tolerance induced by a new selective beta1-receptor antagonist, metoprolol, given by a single administration per os, has been evaluated in 16 patients with stable angina pectoris. The study was a double blind cross-over between metoprolol 100 mg and placebo. Patients were hospitalized for the time required for the performance of the study; every cardioactive drug, except for trinitrine, was stopped 72 hours prior to the study period. Exercise testing was performed two hours after the intake of the drug, in a sitting position on a bicycle ergometer; the workload was increased by 25 Watts increments every two minutes. Compared to placebo, the total workload performed and duration of exercise increased after metoprolol (P less than 0.001), heart rate decreased (P less than 0.001) both in the resting state and during exercise test, systolic blood pressure didn't change in the resting state but decreased during exercise test (P less than 0.01), pressure-rate product, an useful index of changes in myocardial oxygen consumption decreased both in the resting state (P less than 0.001) and during exercise test (P less than 0.001). It is concluded that metoprolol induces a significant increase in exercise tolerance. This is due to a marked reduction in oxygen myocardial consumption resulting by both decreased heart rate and systolic pressure.

Long-term results in 62 cases of post-traumatic complete apallic syndrome.

After the transition state of decerebrate coma, at least four different kinds of the so-called apallic status can be identified: 1. Complete apallic syndrome: coma vigil, alertness without any awareness, mass movements only, impairment of sleep rhythm, absence of any emotional responses, postural abnormalities, some primitive motor responses, tetraplegia, and alteration of muscle tone. 2. Incomplete apallic syndrome: some of the features of the complete apallic syndrome are lacking, and the patient shows emotional reactions with appropriate grimacing and some appropriate motor responses. 3. False apallic syndrome: most signs of complete apallic syndrome are present, but the patient is in touch with the environment. This condition is somewhat similar to the so-called locked-in syndrome. 4. Functional apallic syndrome: full clinical picture of the complete apallic syndrome but full recovery within a few days. Long-term results in 62 patients, aged between 4 and 62, affected by a post-traumatic complete apallic syndrome are reported. Thirty two patients were operated upon and 30 were not operated upon. Out of these cases, 38 died after weeks or months; 3 patients entered a chronic apallic status; 2 patients are improving; 10 recovered with severe neurological or psychic sequels or both; 4 recovered with minimal sequels, and 5 without sequels; no patients in these two last groups were aged more than 20.

Skull changes and intellectual status in hydrocephalic children following CSF shunting.

A total of 76 shunt-treated hydrocephalic children were examined at least once between two and 12-years after surgery to determine what skull changes had occurred and to assess the children's intellectual status. The high incidence of skull changes in shunt-treated, non-tumoral, hydrocephalic children was confirmed. A strict relationship existed between skull changes and low intracranial pressure. The results indicate that impairment of mental development parallels the degree of skull changes, suggesting a close relationship between impaired mental development and cerebrospinal fluid hypotension.
