[Late post-traumatic diaphragmatic hernia: unusual cause of colonic occlusion]. / Ernia diaframmatica post-traumatica tardiva: una rara causa di occlusione colica.

Traumatic diaphragmatic rupture is not an uncommon problem, particularly in the last few years because of the increasing number of road accidents, improved diagnostic techniques and resuscitation techniques after serious traumas. In a certain number of cases, post-traumatic diaphragmatic hernias may become clinically manifest only months or years after thoracic or abdominal trauma and are still a challenge to surgeons because of the vague clinical symptoms and the diagnostic difficulties involved. The Authors report a case of acute colon occlusion due to diaphragmatic hernia 24 months after thoraco-abdominal trauma. None of the radiological or endoscopic examinations demonstrated the presence of diaphragmatic hernia. Laparoscopy showed a diaphragmatic rupture with incarceration of the left colonic segment. The laparoscopic procedure was converted for technical reasons and the diaphragmatic defect was closed with a primary suture.

[Small bowel diverticula in adults: clinical and therapeutic features. Report of 2 cases and review of the literature]. / I diverticoli del tenue nell'adulto. Aspetti clinici e terapeutici. Presentazione di 2 casi e revisione della letteratura.

The true diverticula of the small bowell are a very rare observation in clinical practice; they have a malformative origin and, occasionally, are acquired, contrary to what observed in the colon, where they are frequently an acquired pathology. They can involve the small bowel as a single lesion (Meckel's diverticulum), or as a segmentary disease (duodenal diverticula), or as a diffused diverticulosis. Generally they are asymptomatic and rarely they produce a true pathology. The symptomatic disease is primarily found in pediatric age and it requires a surgical procedure. This makes even more rare the diverticular pathology in the adult. The authors report 1 case of intestinal occlusion due to ileoileo-colic invagination arising from a Meckel's diverticulum and 1 case of intestinal occlusion in presence of a severe and acute diffuse diverticulosis of the small bowell, both in adult patients.

Correlation between disc potency and zone size in temafloxacin activity in vitro.

A multi-test disc potency evaluation of a new fluoroquinolone, temafloxacin, has been prepared in order to evaluate the variation of the zone dimension with the disc antibiotic concentration. A direct correlation between these parameters has been demonstrated. All pathogens have been isolated in hospitalized patients.

Prostacyclin effect on heart rate in the pig.

The purpose of this study was to assess the hemodynamic response after prostacyclin infusion into the venous system and into the carotid artery in the pig. During the study the following circulatory variables were studied: mean systemic arterial pressure, mean pulmonary arterial pressure, wedge pressure, heart rate, cardiac output, systolic and diastolic left ventricular pressure, stroke volume, total systemic resistance, total pulmonary resistance, left ventricular stroke work. Our results confirm that prostacyclin is a powerful hypotensive agent. The hypotensive effect seems to be due to a peripheral vasodilatation of arterial and venous vessels. Venous infusion caused only 19% tachycardia, as opposed to 36% caused by arterial infusion for the same percentage of blood pressure reduction. This suggests that prostacyclin probably stimulates cardiopulmonary vagal receptors. The effect of prostacyclin on heart rate, therefore, may be twofold and in opposite directions: one action causing tachycardia secondary to hypotension, and the other inviting bradycardia through direct vagal stimulation.

[Surgical technic in the treatment of pectus excavatum]. / Note di technica chirurgica nelk trattamento del pectus escavatum.

19 patients subjected to surgery for correction of p.e. have been followed up. The technique adopted is described. The results show the importance of early correction of the malformation and allow the indication to be extended to purely aesthetic needs.

[Pancreatic cystadenoma. Description of 2 cases and review]. / II cistoadenoma pancreatico. Descrizione di due casi e revisione della letteratura.

On the basis of two personal cases and a review of the most recent literature, the main features of this rare pancreatic condition are reported. Special attention is paid to the post-diagnostic importance of radical exeresis. This is the only way of preventing the patient running the risk of malignant degeneration. The observation of a bisalbuminaemic band and the association with an aberrant pancreatic adenoma were of interest in the two cases described.

[Short-term tolerability of 2 types of termino-terminal jejuno-ileal bypass]. / Tollerabilità a breve termine di due tipi di by-pass digiuno-ileale termino-terminale.

The short-term tolerability of two types of end-to-end jejuno-ileal bypasses with different distal ileal loop lengths was evaluated. A comparison was made for 20 days of the behaviour of the main parameters influenced by the malabsorption syndrome thus induced. It was found that the operation involving a greater loss of small intestine was burdened with a greater number of discharges per day, an increase in total water loss, and an elevatem operative risk. This was compensated by more rapid and more evident loss of weight. Evaluation of the real meaning of the inversion of the A:G ratio observed in the short term with this type of operation was postponed to allow a longer follow-up period to run.
