In Italy, a person suffering from a mental disorder who commits a crime will be given a custodial security order and serve the period of admission at a Residenza per la esecuzione delle misure di sicurezza (REMS) (Residence for the Execution of Security Measures, hereinafter "REMS"). These institutions have been established recently and though equipped with the necessary safety measures, the focus is on psychiatric therapy. Despite being present on a national scale, access is very limited in terms of capacity. Immediate remedial measures are needed, so much so that the European Court of Human Rights recently condemned Italy for this very reason. This article, through a review of the constitutive principles of these institutions, shows how they have very positive aspects such as the attention to necessary psychotherapy in order to protect the right to health and the real taking charge of the fragility of the subjects; however, it is seen how there are many negative aspects linked above all to the scarce availability of places in these structures. The article provides suggestions on a more comprehensive strategy for facilities for detainees with mental disorders.

Increased awareness of the spleen's immunologic function and the risk of overwhelming post-splenectomy sepsis has aroused interest in methods of splenic preservation in patients with abdominal trauma. During an 8-year period, 164 patients with documented blunt splenic injuries were treated in accordance with an evolving therapeutic program. Definitive treatment included nonoperative management in 19 patients (group I, 11.6%), repair in 50 (group II, 30.5%) and splenectomy in 95 (group III, 57.9%). Mortality and morbidity were higher in group III (6.3% and 34.3% respectively) according to the Injury Severity Score (ISS 33.3 +/- 13). In group II one patient died from severe head injuries. Only one patient failed nonoperative management and required laparotomy with resultant splenectomy on hospital day 10. Observation without surgery has proved to be safe and effective in children (failure incidence less than 10%); success rates in adults would not parallel the experience reported in children because of differences in anatomy and mechanism of injury. Selective criteria, including hemodynamic stability after initial fluid challenge, normal level of consciousness, lack of peritoneal signs, transfusion requirements of less than 4 units of blood, CT demonstration of minor splenic lesion and exclusion of associated abdominal injuries requiring surgery, make eligible for nonoperative management 12 to 18% of adults with anticipated success in over 75%. Operative repair or partial splenectomy can be employed in many patients, both adults and children, with a 1% incidence of rebleeding necessitating reoperation.

Current knowledge of physiopathology allows better understanding of the metabolic and immunological alterations that occur after trauma, thus allowing more adequate treatment. Nutritional support is recognized as an important therapeutic intervention to promote wound healing, reduce the risk of infection and improve survival. The patient with severe trauma needs nutritional support from the beginning of treatment. The early administration of enteral nutrition is an important factor in the reduction of gut bacterial translocation and thus of septic complications. In the early phase, the parenteral route is capable of providing a sufficient calorific and protein support, whilst awaiting the recovery of the enteral route.

The authors present their experience in the treatment of acute bleeding from oesophageal varices. From 1983 to 1991, 596 patients underwent sclerotherapy during diagnostic endoscopy; a stop to bleeding was achieved in 512 cases (86%). Twenty-seven surgical emergency decompressive shunts were performed, 14 total portal-systemic and 13 selective; operative mortality was 64% and 54% respectively. One patient was submitted to oesophageal-gastric devascularization. Hundred-sixty elective shunts were performed, 99 total portal-systemic and 61 selective; operative mortality was 8% and 11% respectively. Since 1990 3 patients received liver transplantation. The 5-year survival rate of patients submitted to selective shunts was 46%; the 5-year survival rate of nonalcoholic cirrhotics submitted to shunt SRD was 73%.

Imipenem was tested on 65 gram-negative bacterial strains consecutively isolated in patients affected by hospital infection and used as empiric therapy in 52 patients presenting a hospital infection suspected of gram-negative origin. More than 96% of the tested strains resulted sensitive to imipenem. This antibiotic showed a good clinical result in more than 80% of the cases when used as therapy. Therefore imipenem could be considered the drug of first choice in patients with a severe prognosis and a nosocomial infection suspected to be due to a gram-negative microorganism.

The treatment of traumatic ruptures of the duodenum is one of the greatest controversies in surgery. The injury mechanisms, diagnostic criteria and factors underlying the prognosis are analysed and indications suggested for the various types of intervention. The problem relating to the operating technique are specified.

The results of surgery in 5 cases of traumatic rupture of the duodenum are presented. The site of the laceration, the time between trauma and operation, associated lesions, diagnostic routine and type of operation are specified. The mortality encountered (40%) should be related to the seriousness of the lesions.

A rare case of intestinal metastasis of a neuroendocrine carcinoma of the skin (Merkel Cell Tumor) is reported. The primary tumor was excised from the left arm two years earlier and followed an aggressive course with lymph-nodes, tonsillar and intestinal spread. Histologically, the intestinal lesion was similar to the primary tumor with small, undifferentiated cells. Undifferentiated small cell carcinoma and lymphomas of the gastrointestinal tract are to be considered in the differential diagnosis. Merkel Cells Tumor usually affects head and neck (44%) and extremities (48%), and is a highly malignant neoplasia, with early recurrence and distant metastases. Wide surgical excision of the primary lesion is the treatment of choice, while controversial is the role of prophylactic regional lymphadenectomy. Adjuvant radio- and chemo-therapy is frequently associated.

Host immunosuppression after trauma contributes to septic morbidity. The macrophage is a key element in the host immune response. This study evaluated glucan, a macrophage stimulant, in a prospective, randomized, double-blind study of 38 trauma patients undergoing surgery. Glucan (21 patients), 50 mg/m2, or placebo (17 patients) was given intravenously daily for 7 days. Delayed hypersensitivity skin testing was performed on days 1 and 7 after trauma. Serum interleukin-1 (IL-1) and tumor necrosis factor (TNF) were assayed after trauma. While the total mortality rate was significantly less in the glucan group (0% versus 29%) (p less than 0.05), the mortality rate from sepsis was not statistically different (0% versus 17.6%). Glucan therapy significantly decreased septic morbidity (9.5% versus 49%; p less than 0.05). Serum IL-1 had a greater increase in glucan patients on day 3 after trauma (143.4 +/- 19.3% versus 78.6 +/- 11.7%; p less than 0.05), but there was no difference thereafter. Serum TNF did not vary between groups. Early increase in IL-1 correlated with subsequent skin test conversion to positive. Neither serum IL-1 nor TNF was a reliable indicator of future sepsis. Further clinical trials are indicated to evaluate biologic response modifiers that activate macrophages in the trauma patient.

Seventeen cases of segmental portal hypertension due to splenic vein thrombosis are reported. This syndrome may be asymptomatic for a long time and then present suddenly in the form of a serious picture of high digestive haemorrhage due to rupture of gastric fundus varices as a result of hypertrophied submucous collateral drainage circulation. Useful for diagnosis are oesophagogastroduodenoscopy, which points to stomach varices, and splenoportography or splenic artery angiography with venous phase, which highlight pathognomonic dilatation and tortuosity of the gastroepiploic veins. Surgical exploration typically shows: presence of large epiploic vessels, splenomegaly, absence of changes in the liver and in the portal and mesenteric circulation. Curative treatment of choice is splenectomy.

Personal experience in the postoperative treatment of patients with liver traumas is reported, and a comparison is made between those treated in ordinary wards and those admitted to intensive care units. The latter had shorter stays (24 days as opposed to 40) and fewer postoperative complications, assuming a comparable picture of preoperative shock and associated lesions. The difference is attributed to the possibility offered by such units of providing closer surveillance and more rational management.

A colour video picture transmission system in real time with data transmission via a broad wave optical fibre cable has been set up to link Turin University's Orthopaedic Traumatology Centre and Emergency Surgery Clinic. The system consists of two stations. The transmitter station is equipped with a mobile TV camera or TV monitor and various electrical medical equipment. The receiving station consists of a picture reception monitor. The coded video signal is transmitted via the optical fibre; sound transmission is via a special telephone line. This experimental system was set up to see if patients with multiple injuries could receive diagnosis at a distance, thus avoiding unnecessary travelling. Experience of 100 link-ups has demonstrated that the system effectively cuts diagnosis and therapy times and is as efficient as in loco inspection by a surgeon. In addition it can be used to provide specialised consulting services to rural hospitals without special equipment. This reduces waiting times for emergency treatment and can also prevent the pointless transfer of patients to big hospitals in cases where the specialist can prescribe intermediate therapy or surgery.

In this study kidneys were harvested from bred-for-research cats weighing 4 to 5 kg. General principles of donor bilateral nephrectomy en bloc with aorta, vena cava, renal vessels, and ureters were followed. After the harvest the grafts were placed in lactated Ringer slush. A cuff was prepared on the renal vein over a 10 French plastic tube. The aorta was divided and left in connection with the renal artery at each side. Twenty female checkered Flemish giant rabbits weighing 4.0-6.0 kg served as recipients. After premedication with 40 mg/kg of ketamine, anesthesia was maintained with repeated doses (every 10-15 min) of a 0.1-mL mixture of 5 parts ketamine and 1 part acepromazine diluted 50% in a normal saline. Arterial pressure, CVP, blood gases, and temperature were monitored. Through a limited midline incision a native left nephrectomy was performed. The venous anastomosis was performed with a cuff technique without clamping the vena cava (which causes severe hemodynamic instability); the anastomotic time was 2-3 min. The arterial anastomosis was performed with an end-to-side aorta-to-aorta anastomosis; the anastomotic time was 5 to 7 min. There were no episodes of venous or arterial thrombosis. The donor procedure took approximately 40 min, and the backtable preparation of the graft an additional 45 to 60 min. Preparation of the recipient for the anastomosis took 15 min and the anastomotic time (warm ischemia) was 13 +/- 5 min. In this model suitable for xenograft research the duration of the surgery in the recipient has been greatly reduced because of (1) the previous backtable preparation of the graft, and (2) the cuff technique used for venous anastomosis. The present anesthesia regimen and careful hemodynamic monitoring were also important in the success of this model.
