Double-blind double-dummy crossover comparison of the effect of a single dose of cimetidine and trithiozine on gastric secretion.

Twelve patients with duodenal ulcer were admitted to a double-blind double-dummy single dose study in which the H2-receptor antagonist effect of Cimetidine and the activity of Trithiozine, endowed with an unknown mechanism, on gastric acid secretion were compared. For the balanced incomplete block design each patient received two out of four treatments. The single doses tested were 200 and 400 mg of both drugs. Cimetidine reduced all the parameters investigated, while Trithiozine increased basal acid output and acid concentration and did not affect maximal and peak acid output, basal and maximal volume and maximal acid concentration. The multiple range comparison between mean adjusted differences of the four doses were significantly in favour of Cimetidine, except for PAO, basal volume and basal acid concentration, despite the remarkable percent difference between Cimetidine and Trithiozine. In this study, Cimetidine confirmed its inhibitory properties, and Trithiozine did not appear to be an antisecretory agent.

[Aortic dissection: role of the general surgeon in diagnostic-therapeutic procedure].

Aortic dissection occurs when there is a tear or separation of the aortic intima from the media; flow of blood into the intima-media space allows the tear to develop into a dissecting hematoma. Aortic dissection is a rare condition which represents an acute cardiovascular emergency for which the appropriate therapy is immediate surgical correction. Patients with aortic dissection show a heterogeneous constellation of symptoms; hence, clinical suspicion is often difficult. Only a minority of patients has "classic" symptomatology, the electrocardiogram is often misleading and the chest radiogram is almost always non-specific. In Italy, the usual "hospital routine practice" assigns the key-role in the emergency diagnostic procedure for these patients to the general surgeon. In view of the necessity of immediate cardiac surgery and the overwhelming likelihood of adverse events when surgery is delayed, techniques for diagnosis must be accurate, widely available and easily and quickly used. The present study consists of four case-reports of aortic dissection thoroughly examined and confronted with the literature. Management strategy based on emergency echocardiography is a reliable, feasible and successful technique for evaluating patients with aortic dissection. It allows a rapid accurate diagnosis with a single examination that can also be performed in the emergency room and provides information of sufficient diagnostic value to allow immediate cardiovascular surgery. CT scan and/or MRI are also valid tools for the emergency diagnosis of aortic dissection. However, a major problem still exists: the range of symptoms is sufficiently broad that a high index of "personal suspicion" of aortic dissection is required on the part of the general surgeon when he performs the role of "emergency-team leader".

[Adenocarcinoma of the duodenojejunal flexure. A report of 2 clinical cases and a review of the literature].

The authors report two cases of adenocarcinoma of the duodenojejunal angle and remark the rarity of this pathology, the difficulty of making diagnosis peculiar to neoplasm of the small intestine and the difficulty of treatment peculiar to tumours of the duodenum. According to the literature the diagnosis was determined through X-ray films, after traditional endoscopy was inadequate. Surgical treatment is radical, with extensive exeresis procedures (unless the mesenteric upper vessels are infiltrated) since the prognosis of this tumours is good.

[An intramural hematoma of the duodenum].

Intramural hematoma of the duodenum is a rare event which is usually associated with trauma. Because of the rarity of this problem, there has been little conformity of opinions as to diagnosis and treatment of this disease. The authors report on a case of intramural hematoma of the duodenum post-traumatically occurred in a young woman. Etiopathogenesis, diagnosis and treatment of hematoma of the duodenum are thoroughly examined in the present study. Plain abdominal radiography, oral barium study, ultrasound examination, CT and RNM are diagnostic tools in this disease. It appears that most patients with intramural hematoma of the duodenum would respond well to conservative management; surgery should be reserved for those cases that remain obstructed over seven days or have evidence of peritonitis. However surgery is mandatory in cases of uncertain diagnosis. The evacuation of hematoma is considered the most effective and safest surgical treatment.

[Mesh repair of inguinal and femoral hernia].

The authors describe a 6-year experience with mesh repair of inguinal and femoral hernia in a surgical teaching department. Two hundred and ninety-seven hernioplasties were performed in 256 consecutive patients: 237 Trabucco sutureless and 11 Lichtenstein tension-free hernioplasties for inguinal hernia; 21 tension-free hernioplasties for femoral hernia; 20 Wantz GPRVS and 8 Rutkow tension-free hernioplaties for recurrences. Local anaesthesia was used in 59% of cases. Seventy-two patients (28.1%) refused this type of anaesthesia. The hospital stay was two days in all cases. The local postoperative morbidity rate was 8.7% (wound infections: 1.0%; neuralgia: 1.3%; haematomas: 2.0%; seromas: 2.3%; no testicular atrophies). The recurrence rate was 1.9% in the group of patients undergoing surgery from 1994 to 1997 (103 herniorrhaphies; follow-up: 3-6 years) and 0% in the group of patients operated on after 1997 (170 herniorrhaphies; follow-up: 2 years-6 months). The results confirm that the use of a prosthetic mesh (patch and plug) is the treatment of choice for hernia repair. Moreover, this experience in a surgical teaching department shows that these procedures can be safely and effectively performed by all surgeons.
