Abstract
Blindness can be the consequence of trauma, which until now had only been described in cases involving direct facial or cranial trauma. In our case a 53-year-old street worker became irreversibly blind after a thoracoabdominal compression trauma. The investigations performed were inconclusive regarding the cause of blindness. We postulate a massive increase in venous blood pressure with capillary stasis and consequent optic nerve damage. Fat emboli syndrome or posterior ischemic optic neuropathy could be causes, but unrealistic for this case. It still comes into question why such a mechanism has not been seen in other blast injury cases. In the end, the additional factor that resulted here in complete irreversible blindness remains unclear.

Combined copy status of 18q21 genes in colorectal cancer shows frequent retention of SMAD7. Genes Chromosomes Cancer 2001; 31:240-7.

Abstract
Deletions of chromosome band 18q21 appear with very high frequency in a variety of carcinomas, especially in colorectal cancer. Potent tumor suppressor genes located in this region encode transforming growth factor beta (TGF-beta) signal transducers SMAD2 and SMAD4, and inactivation of either one leads to impaired TGF-beta-mediated cell growth/apoptosis. Following the assignment of SMAD7 to 18q21, we first refined the SMAD7 gene position within this region by genetically mapping SMAD7 between SMAD2 and SMAD4. Further, to compare the respective frequencies of genetic alterations of these three SMAD genes in colorectal cancer, we undertook a large-scale evaluation of the copy status of each of these genes on DNA samples from colorectal tumor biopsy material. Among a subset of 233 DNA samples for which data were available for all four genes, SMAD4, SMAD2, and the nearby gene DCC showed high deletion rates (66%, 64%, and 59%, respectively), whereas SMAD7 was deleted in only 48% of the tumors. Unexpectedly, we found some gene duplications; SMAD7 appears to be more frequently amplified (10%) than the three other genes (4-7%). Compiled data for SMAD genes in each tumor show that the most common combination (26% of all the tumors) consists of the simultaneous deletions of SMAD2 and SMAD4 associated with normal diploidy or even duplication of SMAD7. Since SMAD7 normally counteracts SMAD2 and SMAD4 in TGF-beta signaling, we hypothesize that the tumor might not benefit from simultaneous SMAD7 inactivation, thereby exerting selective pressure to retain or even to duplicate the SMAD7 gene.

Abstract
Public perception of organ donation critically affects the availability of organ transplantation in the Western world. To assess the attitude of young adults towards the donation of organs and to investigate potential factors influencing their knowledge and actual behavior regarding organ transplantation, we evaluated a handout questionnaire survey of all Swiss-Italian recruits during six of the years 1989-98 (n = 7272). The attitude of recruits towards organ donation did not change significantly within the 10-year survey period: 61% of young men would personally donate their organs in the case of brain death, 13% would refuse, and 26% had not made up their mind. If they had to decide for close relatives, 50% would consent; 60% of recruits neither knew their next of kin's attitude nor had informed them about their own opinion; 80% felt they were insufficiently informed about organ transplantation. A significantly more positive attitude towards organ donation was found among men who felt they were sufficiently informed, who had close next of kin who were aware of their personal attitude (p < 0.0001), who had contacts with transplanted persons (p < 0.015), or who believed in an existence after death (p < 0.001; chi2-test). Our results suggest that there is potentially large support towards organ donation in this population. To minimize the high rate of indecisiveness, young adults need more appropriate information on the subject and they ask for it.

Abstract
Hospital staff have a key function in asking for potential organ donors, but little is known about their own attitudes towards donation. In a community hospital with 7-8 multi-organ extraction procedures each year 199 staff members were surveyed. Although only 7% of the responding staff would personally refuse to donate an organ, 23 % would not give consent to organ donation from a close relative. 47 % of those prepared to be donors had signed a donor card. Donors informed their family more frequently (88 %) about their personal attitude towards organ donation than non-donors (60 %), or undecided personnel (43,8 %; chi-square P = 0,004). No significant difference in attitude according to medical profession subgroups was found. The findings are in line with general population surveys and indicate that much work needs to be done to encourage medical staff involved in organ donation to set an example to the community.

Abstract
We present the case of a 57-year old man who underwent total parathyroidectomy with autotransplantation into the brachioradial muscle (Wells' method) due to secondary hyperparathyroidism as a complication of chronic renal failure. Three years later the patient developed recurrent secondary hyperparathyroidism due to graft hyperplasia resulting in the removal of the graft. We point out various problems associated with Wells' method and discuss alternative surgical techniques.

Abstract
The correction of complex long bone deformities with concurrent bending, twisting and shortening is primarily based on complex preoperative planning. Up to now, wedge-shaped cortico-spongiose osteotomy has usually been performed. The single cut osteotomy requires more complex mathematical calculations and was therefore less frequently undertaken. In this paper, we present a graphical approach to define the plane of the single-cut osteotomy without any calculations. The resulting osteotomy allows a simultaneous correction of a deformation in the coronal and sagittal planes, as well as a coexisting torsional error. The advantages of this graphical approach are evident. Preoperative planning is significantly simplified and abbreviated as mathematical calculations are no longer needed. Furthermore, the precision by which the osteotomy plane is defined is not decreased by application of this method. However, the osteotomy should be done preoperatively in a model.

Abstract
BACKGROUND Familial adenomatous polyposis (FAP) is a clinically well defined hereditary disease caused by germline mutations within the adenomatous polyposis coli (APC) gene. Although several techniques are applied in the mutation analysis of FAP kindreds about 20-50% of cases remain unclear, with no APC mutation identified (APC negative). AIMS To delineate phenotypic differences between APC positive and APC negative patients with respect to colonic and extracolonic disease in order to determine whether additional mechanisms are involved in the pathogenesis of FAP. METHODS The entire coding region of the APC gene was analysed using single stranded conformation polymorphism and protein truncation tests in 50 Swiss FAP families with a total of 161 affected individuals. Differences in phenotypic manifestation were statistically evaluated by Student's t test, Fisher's exact test, and chi2 test. RESULTS Thirty six families (72%) were APC positive. Statistically significant differences between APC positive and APC negative groups were found for the mean age at diagnosis of colonic polyposis (35.2 versus 45.3 years, respectively) and for the occurrence of stomach polyps (14 patients, all APC positive). Additionally, APC negative patients displayed lower polyp numbers at diagnosis and less extracolonic manifestations. CONCLUSIONS FAP kindreds without detected APC gene mutations present with a notably milder disease phenotype compared with APC positive families, suggesting that different genetic factors might be involved.

The diaphragmatic injury can easily be overlooked. This report illustrates the diagnostic dilemma in a patient where the injury was missed at the time of initial presentation. The role of thoracoscopy both for diagnosis and therapy is discussed.

Abstract
BACKGROUND We evaluated the advantages and risks of laparoscopic cholecystectomy during pregnancy in symptomatic patients. MATERIAL AND METHODS Three gravid women at an estimated 14 to 26 weeks gestational age underwent laparoscopic cholecystectomy for symptomatic cholelithiasis or biliary pancreatitis. One patient was obese. The operation was successfully completed under tocolytic medication. DISCUSSION Although rare, gallbladder disease is the second most common abdominal condition during pregnancy requiring operation, being second only to appendicitis. Medical management is the most common approach to treatment, and the surgical intervention is reserved for patients who fail to respond to conservative methods or who have choledocholithiasis, biliary obstruction or pancreatitis. The laparoscopic approach is controversial, and some authors still agree that pregnancy is a contra indication to laparoscopic cholecystectomy. We report our experience with three laparoscopic cholecystectomies performed without complication during pregnancy. On the basis of our experience and a review of the literature, we believe that the laparoscopic cholecystectomy, undertaken preferentially during the second trimester, is a valid alternative to classic management in terms of risks for the foetus and comfort for the mother.

Abstract
Meckel's diverticulum is the most common anomaly of the gastrointestinal tract. Neoplasms are extremely rare. We report a case of carcinoid tumor of Meckel's diverticulum in a patient with acute abdominal pain. So far, 111 cases have been reported. Review of the literature reveals that carcinoids are the most common malignant tumors of Meckel's diverticulum. Two thirds of the patients remain asymptomatic. Metastases are seen in 25% at diagnosis. The probability of metastases depends on the size of the primary tumor. Because of the early metastases rate even in small tumors, aggressive surgical management is justified.

Abstract
Between 1981 and 1993, 27 bronchial carcinoids were diagnosed in patients living in the Swiss Canton of Ticino, with a mean age of 55 (24-78) years. The incidence was 0.79/100,000 inhabitants. Main symptoms were cough (41%), hemoptysis (30%) and bronchial obstruction such as pneumonia or atelectasis (26%). There were no cases with carcinoid crisis. Preoperative evaluation included chest X-ray (100%), bronchoscopic biopsy (84%), computed tomography (44%) and mediastinoscopy (15%). Some 69% of the patients underwent lobectomy and 15% segmental resection. Pneumonectomy was required for curative surgery in 2 patients. One patient underwent bronchoscopic resection. Surgery is generally indicated. The 5-year survival rate for typical carcinoid was 94% and was significantly reduced to 42% in atypical carcinoid cases (p = 0.02). Prognosis after radical surgery is favorable and depends mainly on lymph node involvement and the histological type of carcinoid.

Abstract
Ischemic preconditioning (IP) refers to a phenomenon whereby short periods of ischemia reduce tissue damage after a subsequent sustained ischemia. The effect of IP before tourniquet ischemia of the extremities has not yet been evaluated. We developed a rat model of skeletal muscle ischemia and measured the effect of IP on postischemic function and high-energy phosphate levels. IP consisted in three cycles of 10 min ischemia and 10 min reperfusion each. IP improved significantly skeletal muscle function after 3 hours of ischemia and 2 hours of reperfusion. High-energy phosphate levels, however, remained unchanged. This study shows a protective effect of IP in skeletal muscles. These results furthermore suggest that the protection of energy metabolism is not a mechanism of IP in this model. IP could be easily performed before surgery of the extremities under tourniquet ischemia. The protective effect on postischemic skeletal muscle has therefore to be further investigated.

The treatment with allopurinol demonstrates of on benefit or phosphocreatine and ATP kinetics. These results outline that reutilization of hypoxanthine doesn't represent a protective mechanism of allopurinol on skeletal muscles. The role of hypoxanthine reutilization has to be investigated with further researches.

Abstract
The APC gene is mutated in the germline of people from families where there is a predisposition to develop polyposis coli. Many mutations have been described but the relation between their site and the phenotypic expression of the disease remains unclear. The most commonly seen mutation occurs at codon 1309. Many other mutations have been described towards the 5' end of exon 15 of the APC gene but comparatively few have been seen towards the 3' end. Recent reports have indicated the possibility of a functional boundary with respect to severity and age of onset of disease, which lies towards the 5' end of the gene. This report describes a large family whose affected members present with a very variable phenotype ranging from an early onset and severe form to a comparatively mild later onset one. The mutation that predisposes to disease in this family is at a previously undescribed site that lies towards the 3' end of exon 15 of the APC gene, which results in a stop codon. Interestingly, the stop codon is 63 codons downstream of the mutation and therefore may affect the expression of the disease. The addition of this mutation to the growing list of mutations described in the APC gene may provide some insight into the genotype/phenotype relation of the disease thus contributing to the understanding and significance of mutations at specific sites in the APC gene.

Abstract
The localized fibrous tumors of the pleura are rare neoplasms, also known as "benign pleural fibromas" or "localized mesotheliomas", but those names are inaccurate. The tumors are composed of undifferentiated mesenchymal cells, intermediate and differentiated fibroblasts and collagenous interstitial tissue. Their origin is normally the submesothelial layer of the visceral pleura. Mesothelial differentiation is not present. The grading of malignancy doesn't correlate with final outcome, adequacy of surgical excision being the most important factor. This neoplasm may recur but retain its basical histologic features. The positive results for vimentin and negative results for cytokeratin antibodies help to distinguish the localized fibrous tumors from the mesothelioma. We present too cases and their diagnostic possibilities.

Abstract
During the last years the cases of severe group A streptococcus infection have increased. The clinical manifestation of this streptococcal toxic shock syndrome is similar to the better known toxic shock syndrome (TSS) provocated by staphylococcus. Shock, bacteremia and acute respiratory distress syndrome are common features, and death has been associated with this infection in 30% of patients. We present the case of a 46-year-old man who fell gravely ill with sepsis, diarrhoe, scarlatina rash, desquamation of hands and feet and acute abdomen caused by group A streptococcus infection. Finally we discussed the possible port of entry of this infection, the different clinical manifestation and the concepts of treatment.

Abstract
The management of severe hepatic trauma may represent a challenge in the presence of haemodynamic instability, coagulopathy, hypothermia or metabolic failure. Moreover, the choice of treatment should consider the prevention of complications. The omentum has many advantages including hemostasis, infection preventing, viability and adaptability to reconstruction as a space filler. We report the case of a 19 year-old patient who sustained a gunshot wound, involving the right elbow and forearm and the abdomen with burst of right kidney and a penetrating centro-hepatic injury (stage IV). Surgical treatment was successfully performed in two times, by gauze packing for temporary control of haemostasis and after 24 hours by omental packing to fill the dead space of hepatic lesion. The viable omentum was placed through the hepatic hole and fixed posteriorly to the skin. The postoperative period was uneventful, excluding the development of a biliary fistula which resolved after external drainage. We conclude that omental packing is a valid solution when dealing with penetrating liver injury.

Abstract
533 patients with diagnosis of operable colorectal carcinoma were randomized to receive either a single course of portal infusion with Mitomycin-C (MMC) and 5-Fluorouracil (5-FU) starting immediately after operation, or no adjuvant treatment. Of these, 505 (94%) were evaluable. Over the median follow-up of 8 years, the adjuvant therapy reduced the risk of recurrence by 22% (Hazard ratio = 0.78%, 95% CI 0.61-0.99; P = 0.045). The relative reduction of relapse on death was similar in all subgroups (i.e. nodal status, localization). However, adjuvant portal chemotherapy proved to be most efficient in the subgroups of patients with tumor involvement of the regional lymph nodes (Dukes C) and of patients with colon cancer. Analysis of the pattern of relapse showed that most of the difference in overall and disease-free survival is to be attributed to a consistent reduction of all kinds of tumor recurrences (i.e. local relapses, liver metastases and/or other distant metastases) in the treated group, rather than to liver relapses alone. We conclude therefore, that part of significant benefit obtained for patients with operable colorectal carcinoma treated with a single course of adjuvant chemotherapy via the portal vein might be due to the additional systemic effects of the portal chemotherapy and further study of perioperative treatment with and without prolonged chemotherapy appears worthwhile.

Many victims of tragic accidents get lifetime disabled. Direct and indirect costs of traffic injuries are yearly 3 billions of swiss francs. Only a small percentage (6%) is devoted to medical treatment. The most part is due to compensation of income, disability with its allocations and lost productivity. Among "avoidable" deaths, traffic victims are an essential portion because the are young. More efforts should be undertaken to lower road mortality because she erodes the swiss population pyramid in a significant manner.

Abstract
The present retrospective study evaluates 197 mediastinoscopies, performed between 1981 and 1990. The aim of the study was an actual evaluation of mediastinoscopy as an investigation for diagnosis and staging of intrathoracic diseases. Although the introduction of CT-scanning has caused a considerable decrease in the number of performed mediastinoscopies per year, we find that mediastinoscopy because of its high sensitivity (75%) and specificity (100%) still has an important place in the evaluation of intrathoracic diseases. It represents no alternative to CT, but a complementary diagnostic tool. As a conclusion four indications for mediastinoscopy today are proposed.

Abstract
Little is known about the consumption of medical and surgical services by the most informed consumer in the health care market: the physician-patient. Such knowledge should be important for the understanding of the role of information on consumption, supplier-induced demand, the doctor-patient relationship, unnecessary medical services, and the adequacy of professional practices to the renal health needs of the "ordinary patient." We measured by questionnaire the standardized consumption of seven common surgical procedures. Except for appendectomy, the age- and sex-standardized consumption for each of the common surgical procedures was always significantly higher in the general population than for the "gold standard" of physician-patients. The data suggest that (a) contrary to prior research, doctors have much lower rates of surgery than does the general population; and (b) in a fee-for-services health care market without financial barriers to medical care, less-informed patients are greater consumers of common surgical procedures.

Abstract
Through indirect ophthalmoscopic examination it was possible to analyse three families originated from the same Swiss alpine valley (Poschiavo) and carrying Gardner syndrome (SdG) to check if their members with SdG were presenting hypertrophic changes of the retinal epithelium which is supposed to be an early symptom of that syndrome. This lesion was found to be present only in two out of 11 patients (18%) with at least one symptom of SdG. Because of its lacking sensitivity, ophthalmoscopic examination is not able to substitute colonoscopy as a valid screening method to find out which members of a SdG-family are at risk to develop colonic poliposis and cancer.

Abstract
The IMT-NV system proposed by the AO-ASIF for classifying soft tissue injuries associated with long bone fractures allows to avoid the troubles of the historical discussion between two different opinions: which is the most important feature of an open fracture? The extent of the skin lesion or the deeper muscular and neurovascular damage? This classification as it is proposed in the new AO-manual will bring more precision and more possibilities in comparing different surgical approaches to this hard challenge called open fracture.

Abstract
Between 1981 and 1987, 533 patients from 9 institutions have been entered in a randomized trial to assess the value of adjuvant portal infusion (5-Fluorouracil, Mitomycin C) compared to radical surgery alone. Analysis of 469 evaluable patients at a median follow-up of 5.8 years revealed 110 recurrences in the control and 94 recurrences in the infusion group. Estimated 5-year disease-free survival was 52% and 61% respectively (hazard ratio 1:0.75; 95% confidence interval 0.57-0.99; p = 0.046). Overall survival was 59% in the control and 69 in the infusion group (p = 0.048). Adjuvant portal infusion did not influence the occurrence of liver metastases but reduced the overall recurrence rate.

Abstract
We analysed the esophageal manometry of 36 patients before, and of 25 patients 1 to 14 years (5.8 years) after, fundoplication. The results were compared with the findings in 30 asymptomatic volunteers. Fundoplication raised the mean lower esophageal sphincter pressure from 6.2 mm Hg to 14.5 mm Hg, i.e. normal values (controls 20.2 mm Hg). The shortened lower esophageal sphincter length and its intraabdominal segment were overcorrected (increase from 3.2 to 5.2 cm [controls 4.1 cm] and 1.3 to 2.6 cm [controls 2.1 cm] respectively). The rate of non-specific motility disorders after fundoplication was reduced from 61% to 28% (controls 7%). A clear relationship between the success of fundoplication and either preoperative or postoperative manometric results could not be established.

Abstract
A prospective, randomized trial of adjuvant portal infusion of 5-fluorouracil in combination with mitomycin C was conducted on 469 patients with operable colorectal cancer. A single postoperative course of the cytotoxic agents was compared with radical surgery alone. The actuarial 5-year survival (median follow-up 48 months) was 70 +/- 3% in the chemotherapy group and 57 +/- 4% in the control group (p = 0.10). The respective figures for disease-free survival were 62 +/- 4% and 53 +/- 4% (p = 0.09). Among the 195 cases with strict adherence to the protocol for adjuvant chemotherapy there were 59 recurrences and 44 deaths in the follow-up period, whereas in the 274 with no or incomplete chemotherapy there were 120 recurrences and 99 deaths (p less than 0.05). Perioperative adjuvant chemotherapy via portal infusion proved to be feasible in a multicenter setting. Follow-up will be continued, in order to provide definitive information on survival according to randomization.

Abstract
More recently a number of retrospective analyses in rather ill defined patient populations demonstrated an association between perioperative blood transfusion and recurrence after curative resection of colorectal cancer. In the randomized trial (SAKK 40/81) (adjuvant cytotoxic intraportal infusion versus no further treatment) we evaluated the transfusion status in a well defined, prospectively documented and controlled patient population. Of 457 patients, 353 (77.2%) received either pre-, intra- or postoperatively blood transfusions. After a median follow-up of 4 years, the transfused patients developed significantly more recurrences (38.2%) than patients without blood transfusions (23.1%), the death-rate being 33.7% versus 23.0%, respectively. Patients without transfusion but treated with adjuvant intraportal chemotherapy are strikingly doing better (10.5% recurrences) than patients with perioperative blood transfusion not having an adjuvant treatment (44.5% recurrences).

Abstract
Between July 1981 and June 1987, 533 patients from 7 participating institutions have been entered in a prospective randomized trial to assess the value of adjuvant portal infusion (5-Fluorouracil 500 mg/m2/d x 7 continuous infusion + Mitomycin-C 10 mg/m2 on day 1 as a bolus injection through portal venous catheter) compared to radical surgery alone. The portal venous catheter was placed through any side-branch of the mesenteric venous system during laparotomy for the primary tumour. Using the transabdominal route, there have been no catheter-related complications. Overall hospital mortality in the study was 1.75% and was not influenced by adjuvant treatment. Analysis of 469 eligible patients at a median follow-up of 48 months revealed 39.1% recurrencies in the control group and 31.8% in the infusion group (p = 0.09, logrank). Median survival of control patients is 72 months, of chemotherapy treated patients not yet reached. Significant survival advantages have been detected for those 195 (85%) patients who received full-dose adjuvant chemotherapy (67% versus 53% 5-year survival). Due to the low number of deaths in this trial, prolonged follow-up is needed for definitive survival conclusions.

Abstract
In the paper we present the results of an epidemiological study we conducted upon injuries due to road accidents in Canton Ticino. We investigated into 1471 injured patients admitted to hospital during 1982 in Canton Ticino, all the in- and out-patients at the Ospedale Civico during 1985 and all the seriously injured patients in road accidents where the scientific police (SIR) were called in. 106 (8%) patients died, 206 (15%) were seriously injured (87 patients with chronic infirmity) and 1062 had slight injuries. The total lesions were 2900 and 839 surgical operations were necessary. These patients needed a total of 7804 days of hospitalization (677 days in the intensive care unit). Motorcycles represented 46.5 of the involved vehicles. The major risk groups by age are: 14-17-year-olds (motorcyclist), 18-29-year-olds (automobilists and motorcyclists), up to 13 and over 60 years of age (pedestrians). The percentage of the total road accidents which occur at the week-end is of 49.4%. At peak hours (17.00 p.m.) the percentage of accident is 8.1% (115 accidents) and in the small hours the percentage is of 5.5% (74 accidents). The annual hospitalization costs amounted to 3,200,000 SFr., whereas the real costs corresponding to production loss, social expenditures (25.737 were the days of disability) and in- and out-patient care are as high as 100 million francs.

Abstract
Three years after surgery on average seventy patients with surgically "treated" or "repaired" lesions of the anterior cruciate ligament were evaluated. According to the operative technique, the patients were divided into 4 groups: Group I: suture of ligament only, Group II: Eriksson-Trillat plasty, Group III: McIntosh plasty, Group IV: Dacron plasty. The results were assessed according to the Marschall-score. Good results were obtained in the first group. The results with the fourth group were at the time of the examination "good" too, however, one third of them had to be reoperated in the following six months. For fresh ruptures of the ACL we advocate the primary suture of the ligament with, if necessary, an augmentation.

Abstract
We report our experience with 11 patients treated with an external fixator that was dynamized at some stage of the treatment. In 7 patients bone union occurred without any other measures, 2 patients were protected in a cast after the external fixator removal, while 2 patients developed a non union that was plated and subsequently healed. According to these experiences, dynamization of an external fixator seems to be a reliable and elegant way to treat simple open shaft fractures, the method is however not advocated for more complex or comminuted fractures.

Abstract
Analgesia is an important problem in myasthenia gravis patients who have undergone transsternal thymectomy. Postoperative pain interferes with pulmonary function, which is already limited by the disease. The choice of medication is restricted because many analgesics are synergic to the myasthenia gravis syndrome and detrimental to the patient. Three patients with severe myasthenia gravis are presented who had undergone transsternal thymectomy with good postoperative results. They received high thoracal epidural anesthesia (C7-Th1/Th1-Th2/Th2-Th3) with a solution of bupivacaine and morphine (20 ml 0.25% bupivacaine with 10% morphine). The patients were extubated in the first 48 hours and monitoring of respiratory function (CV2, PO2, PCO2) showed satisfactory values. With this type of analgesia we obtained early mobilization and good patient cooperation. Although limited this favourable experience confirms that high thoracal epidural anesthesia is a sure technique which allows rapid weaning from the ventilator and maximum comfort for the patient. It avoids the use of other medication or analgesics which are contraindicated in these patients.
