Myelolipoma is a rare, benign tumour composed of fat and hematopoietic cells. Abdominal pain is often the only symptom and the result of compression by the tumour of contiguous organs. A personal case is reported after a review of the literature.
Malignant duodenocolic fistula is a rare condition in which radical surgical treatment is seldom possible. A personal case treated by pancreaticoduodenectomy is presented with a review of the literature.
By psychophysiologic training of internal and external rectal sphincters five incontinent subjects managed to recover a complete or incomplete self-control in very difficult situations, such as outcomes of surgical sphincter lesions, depression equivalents and ischemic nervous sufferings. So anus incontinence (perhaps preternatural anus incontinence) could be faced by means of biofeedback, especially if similar home sessions were associated.
Colonsphinctorometrography (CSMG) is a new, original method for the simultaneous investigation of the motility of the descending colon, sigmoid colon, rectosigmoid junction, rectum, and internal and external anal sphincters. A 60 cm open-ended tip sound with an external diameter of 10 mm is used. Three 3 cm long stimulating balloons are located at points 15 cm, 30 cm, and 50 cm along its length. A basal recording is taken for about 15 min with the patient absolutely at rest. The balloons are then inflated to measure the kinetic responses of colon and anal sphincters to stimuli of different volume. In addition to offering a pressure recording for the left colon and internal sphincter, the method also provides an EMG for the external sphincter and a pneumogram.

Surgical treatment of multinodular goiter is still now discussed: total versus subtotal thyroidectomy. Advantages of partial thyroidectomy are the low incidence of laryngeal nerve injury and the low risk of hypoparathyroidism. Disadvantages are the increased recurrent disease, the risk of carcinoma, the elevated possibility of laryngeal nerve lesions and permanent hypoparathyroidism after reoperations. Own experience regarding 401 thyroid operations is reported; 60 patients were operated for multinodular goiter; 48 subtotal and 12 total thyroidectomy were performed. Among those 1 (1.65%) inferior laryngeal lesion and 1 (1.65%) permanent hypoparathyroidism occurred. Anatomic knowledge and correct surgical procedure give a reduction in the mobility of total thyroidectomy which in selective case can be considered the treatment of choice.

A colosphincterometrographic study in 40 normal subjects revealed the existence of a colosphincteral reflex hitherto unknown to man. In all cases, insufflation of 30-40 cc air into a balloon placed 50 cm from the anus produced a relaxation of the internal sphincter muscle of the anus (colosphincteral reflex), a subjective feeling of imminent defaecation, and reflex contraction of the external sphincter muscle. The discovery of this new reflex suggests that the physiological mechanism of defaecation may even commence above the ampulla recti, which has always been regarded as the only reflexogenic segment of the large intestine.
