Liver resection for hemoperitoneum caused by spontaneous rupture of unrecognized hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is an increasingly common form of cancer. Although its spontaneous rupture is rare in Western countries, it constitutes a surgical emergency and is associated with high mortality. There is a lack of consensus as to the best approach and what parameters to use in choosing it. The three main approaches are conservative, endovascular and resection - the treatment of choice for acute abdominal bleeding. We report a case of hemoperitoneum following the spontaneous rupture of an unrecognized HCV-related HCC in a patient with no history of liver disease. The patient was successfully treated by emergency surgery, with resection of two segments of the left liver.

[Traumatic retroperitoneal haematoma]. / L'ematoma retroperitoneale post-traumatico.

The management of traumatic retroperitoneal haematomas is still a much debated question. Although the diagnosis has become easier using CT with contrast medium, the therapeutic decisions are still difficult because of the great variability of the lesions, which may be simple but very often complicated. Our study is based on 1086 treated patients, 29.5% of the 3682 critical abdominal polytrauma seen in 35 years. Mortality has been 12.9% with a medium ISS (Injury Severity Score) of 23.4. 71.4% of the cases were closed traumas, 28,6% were open traumas. The most common single lesions have been pelvic (43%), followed by the renal traumas (39%). Regarding the associated lesions, the thoracic traumas cause an increment of the ISS score up to 26.2% and of mortality up to 14.6%. The maxillofacial traumas associated with traumatic retroperitoneal haematomas represent 11%, mainly associated with motorcycle accidents, which have increased in the last years from 2,4% in the 70s to 32% these days. Our approach to these patients has been basically conservative. Following the indications obtained by the CT, we widely used interventional angiography, especially for renal lesions and, after pelvic stabilization, for pelvic haematomas. We have chosen surgery considering the kind of traumas (open or closed), the location of the haematoma and especially, the clinical course of the patient's hemodynamic condition.

[Total thyroidectomy: initial experience of a territorial reference center]. / La tiroidectomia totale: esperienza iniziale di un centro di riferimento territoriale.

Authors report their initial experience in surgical treatment of thyroid diseases in an area with high percentage of thyroid tumors. Since January 2006, we examinated 428 patients. By clinical features, hormonal profile, imaging and US-guided FNAB, we selected 134 of them for surgery; 93 patients underwent thyroidectomy in January-November 2006. The Authors analyse therapeutic choises and surgical techniques, stressing the high percentage of thyroid neoplasms.

[Gastrointestinal opportunistic infections and human immunodeficiency virus (HIV). Case report]. / Infezioni opprtuniste gastrointestinali e HIV. Caso clinico.

There have been millions of people found to have AIDS. Death rates from AIDS have declined 15% to 20% in the past 5 years. However, nearly 75000 people will die with AIDS in this year. Patients with AIDS are also at risk for developing both Aids-defining cancers, such as Kaposi's sarcoma and non-Hodgkin lymphoma, and non-Aids-defining cancers and opportunistic infections. In patients with advanced Aids, the Cytomegalovirus is a frequent cause of chorioretinitis, pneumonitis, chronic perineal ulcerations and oesophagitis. It has been involved in endocrine, bone marrow, central nervous system and kidney abnormalities. CMV infection of the small bowel accounts for only 4.3% of all cytomegalovirus infection of the GI tract (large bowel 47%, duodenum 21,7%, stomach 17,4%); isolated cases of small bowel perforation due to CMV have been reported in AIDS patients, and all but one patient died. The Authors report a rare case of an HIV-positive young man with gastroenteric Cytomegalovirus infection responsible for generalized peritonitis from multiple perforations.

Survival in kidney transplantation from living donors: a single-center experience.

BACKGROUND: Transplantation from living donors, in Italy, is still not accepted, in particular those from unrelated donors. The aim of this paper was to present the experience of one transplant center. MATERIALS AND METHODS: Since 1982, 608 transplants were performed from living donors using cyclosporine as the main component of immunosuppressive therapy. Among those, 402 transplants were from related living donors (338 one haplotype pairs and 25 zero haplotypes pairs) and 206 from unrelated living donors (171 spouses and 35 emotionally related subjects). RESULTS: Graft survival at 1, 5, and 10 years showed no statistically meaningful difference between the two groups. A group of 19 transplants performed in predialytic phase patients was compared with a contemporaneous group of 167 transplants performed in patients who were already receiving dialysis. These two groups did not show any statistically meaningful difference in graft survival at 1, 5, or 10 years. DISCUSSION AND CONCLUSIONS: We think that transplants from living donors, whether related or unrelated, must always be proposed as a therapeutic option for end-stage renal disease patients, since they show an higher graft survival than that from cadaveric donors, independent of the compatibility between donor and recipient and independent of the degree of relationship of the pair. Transplantation from living donors definitely is a complementary, not substitutive, program to that from cadaveric donors, which should always be encouraged with awareness campaigns among the population and targeted programs for healthy personnel.
