[Perforated diverticulitis of the colon: modalities of the surgical treatment].
A retrospective study was carried on 66 patients surgically treated for perforated diverticular colonic disease: 22 had acute phlegmon or pericolic abscess and underwent primary resection and anastomosis. Of the remaining 44 patients, who had multiple pericolic and/or pelvic abscesses, or generalized peritonitis, in 30 cases the Hartmann procedure was used, 6 underwent Mikulicz operation, while drainage with proximal colostomy was performed in 5 cases, and simple suture and drainage in the last 3 cases. Operative mortality was 18.2%. Mortality rate was higher in patients treated by colostomy and drainage. The Hartmann procedure and resection-anastomosis patients had a mortality rate of 23.3% and 4.4% respectively. No mortality was registered among patients treated with suture and drainage.

[Leiomyosarcoma in jejunal diverticulum. A case report and review of the literature].
The Authors describe a case of double jejunal diverticulum, characterized by the presence of a leiomyosarcoma in one diverticulum and ectopic pancreatic mucosa in the other. The rarity of the occurrence of a leiomyosarcoma in the diverticular area is outlined; only few cases have been reported in Literature, excluding those originating, from Meckel's diverticulum. Barium X-rays of the small intestine allowed the neoplasia to be discovered, while an Echo-Color-Doppler examination suggested the histological type given the high vascularization typical of leiomyosarcomas.

Lung cancer in young patients.
Despite the increasing frequency of lung cancer, the percentage occurring in young patients is very low (1.3-5.5% of all lung cancers). In 1992, of the 78,124 cases observed in Italy, 2.8% involved patients under 40 years of age. We reviewed a series of 800 patients with histologically proven lung cancer, candidates to a long-term follow-up. Of these, 23 (2.9%) were under 40 years of age, with a low male/female ratio (1.87:1). Fifty-two percent were smokers and 82.6% presented symptoms as the time of diagnosis. The most frequent histologic types were adenocarcinoma and large-cell type, which carried a better outcome (10-year survival of 28.5%) than epidermoid and small-cell types (p = 0.013). These tumors detected in 13% and 17.4% of cases, were unresectable (except for one epidermoid carcinoma), with a survival expectancy of 0% at two years. Considering all patients, resection was possible in nine cases, being curative in seven, with an overall 10-year survival rate of 44.4% (p = 0.002 vs non-resected patients). Stage I-II had the best prognosis with a 10-year survival rate of 80% (p = 0.022 vs resected stage III-IV). Patients undergoing primary chemotherapy and/or radiotherapy had the worst prognosis with no survivors at 30 months. In young patients clinical and pathological parameters had almost the same distribution except for sex and histologic type and offered almost the same survival probability as in patients over 40 years of age. When prognostic findings were tested by univariate analysis, only resectability was found to have an independent favourable impact on survival (hazard risk: 7.47; 95% confidence interval: 1.50-37.14).

[Update on deep thrombophlebitis and pulmonary thromboembolism].
Pulmonary thromboembolism, a frequent complication in deep vein thrombosis, is still a pathology with a high rate of mortality and morbidity. The authors underline that this pathology is particularly frequent after some types of surgery and in subjects with primary or secondary risk factors. The paper analysis the pathogenesis of deep-vein thrombosis and the physiopathology of pulmonary embolism. The authors then outline the current management in terms of the diagnosis, prophylaxis, and medical and surgical therapy of this pathology.

Amplitude and speed change of the optokinetic response in patients with and without neglect.
The present study quantitatively investigated the slow and quick phases of optokinetic nystagmus (OKN) in four groups of patients: right unilateral brain-damaged patients with neglect, left and right patients without neglect or hemianopia and patients with left or right retrogeniculate lesions and lateral homonymous hemianopia. Our results indicate that only neglect patients show a perturbation of both components of OKN. A comparison among MRI images of different patients shows that a region involving area 37 and adjacent areas 39 and 19, was impaired in all patients with neglect, but not in any other patient with either right or left lesions.

Simultaneous determination of plasma levels of alpha-ketoisocaproic acid and leucine and evaluation of alpha-[1-13C]ketoisocaproic acid and [1-13C]leucine enrichment by gas chromatography-mass spectrometry.
A sensitive method for the simultaneous analysis of plasma alpha-ketoisocaproic acid (KIC) and leucine using GC-MS is described. Plasma was deproteinized after addition of both alpha-ketovaleric acid and norleucine as internal standards. Derivatization of the compounds involved protection of the keto groups with methoxyamine and tert-butyldimethylsilylation under optimized conditions. Mass spectral analyses were carried out in electron impact ionization mode and the gas chromatographic conditions selected prevented interference by other keto acids and amino acids normally present in plasma or by the biological matrix. Determination of both plasma levels and isotopic enrichment of KIC and leucine required a single injection and was easily accomplished in 7-9 min. The good reproducibility of the method, in addition to rapidity and simplicity, permits several samples to be accurately analyzed daily. Therefore, the method is particularly useful for studies on the metabolism of amino acids.

[Current trends in the treatment of giant nonparasitic cysts of the liver].
The authors report 10 cases of giant non-parasitic congenital cysts of the liver (7.7-25 cm in size). All the patients were symptomatic; preoperative ultrasonography was diagnostic in all cases allowing to discover the cyst. Six patients underwent partial resection of the cyst (in one of these a cystojejunostomy was performed), while atypical hepatic resection was performed in two cases, enucleation in one and left lobectomy in another case. No evidence of malignant degeneration was found in the histologic study of the specimens. No mortality nor morbidity were registered. All patients were followed up for 1-20 years and no recurrences were found. The authors point out that partial resection of the cyst is a safe operation with good immediate and long-term results.

Intracystic carcinoma of the breast. Our experience.
Malignant tumours of the breast occurring as cysts present an incidence from 0.3% to 0.7%. The Authors report their experience during 15 years in 470 patients with carcinoma of the breast. Endocystic carcinoma appeared in 0.6% of patients: the diagnosis is not always possible with cytology, but ultrasound scans make possible to identiphy cysts which have to undergo biopsy because solid areas within the cystic cavity have been detected. In this case surgery is advised even if the cytological examination has been negative.

[The use of a transillumination method for locating the subclavian vein for its catheterization. A preliminary study].
After commenting brief on the complications related to the cannulation of the subclavian vein, the paper outlines a simple and original method for finding the latter. An illuminator optical fibre is inserted in the fore region of the elbow and this enables the subclavian vein to be located by transillumination.

[Risks and complications of total parenteral nutrition. Personal experience].
Total parenteral nutrition is now a broadly used method whose efficacy is confirmed, even if it is still not free from risk of complications. The Authors report their own clinical experience on 130 cases in the period 1981-1988. Complications were registered in 4.6% of the observed cases. They underline the problems relating to this subject.

[Angioplasty of the deep femoral artery using a semirigid PTFE prosthesis. Experimental studies].
Underlining the importance of Profundus Femoral Artery and its capacity to make up for lower limb's haemodynamics during obliterative arteriopathy, the Authors conceive a funnel-shaped intravascular prosthesis, Goretex constructed (PTFE), to introduce, in case of obstruction, in the artery lumen with a suitable instrument. The research is performed through ten oldster dogs whose average weight is twenty-four kilograms. Isolated the deep Femoral Artery and carried out an arteriotomy of about two centimetres on the Common Femoral Artery, we bring the prothesis in Profundis Femoral Artery and we fix it to the wall of the Common Femoral Artery with 8/O microsurgical dots. After thirty days, the arteriographic test shows the patency of the endoprosthesis with normal peripheral flow in nine animals out of ten. By virtue of this preliminary experiment, the Authors point out the semplicity of this intervention, also feasible in local anaesthesia, the good tolerability of the prosthesis and its perfect integration with the surrounding arterious wall, without shifts or dissecting laminar flows between the external prosthesis wall and the vessel lumen of the animal.

[Radical surgery and loco-regional chemotherapy in the treatment of liver metastases of stomach and colorectal cancer].
The results of surgical treatment of hepatic metastasis from stomach and colo-rectal cancer in a series of 28 patients have been assessed. 21 cases were subjected to hepatic resection (stomach cancer: 7 cases; colorectal: 14 cases) and 7 underwent locoregional chemotherapy through the gastroduodenal artery with fully implantable catheters (stomach ca.: 1 case; colorectal ca.: 6 cases). Of patients who underwent hepatic resection, 3 died postoperatively and 4 are still alive 5 years after the operation. Of the 7 patients treated with locoregional chemotherapy, 4 can be evaluated: 2 responded to treatment, 1 stabilised and 1 progressed. Clinically noteworthy toxicity was observed in one patient only.

[Etiopathogenetic and histopathologic aspects of acute necrotico-hemorrhagic pancreatitis in experimental animals].
In this study, the Authors have provoked experimentally acute pancreatitis in the rat by different methods, in order to find out morphological modifications of the pancreas in the initial stage of the disease. In case of biliary and pancreatic duct obstruction with pure pancreatic reflux, both oedema and inflammatory infiltrations were evident, whereas, in the presence of biliary reflux too, more serious histological features were detected. In conclusion, the first sign of alteration in acute pancreatitis could be represented by the association of intraductal hypertension and pure pancreatic reflux.
