Prevention of intrahepatic recurrence by adjuvant (131)iodine-labeled lipiodol after resection for hepatocellular carcinoma in HCV-related cirrhosis.
AIM: To evaluate the impact of postoperative injection into the hepatic artery of 131-iodine-labeled lipiodol on disease-free and overall survival rates in patients who underwent liver surgical resection for hepatocellular carcinoma. METHODS: Ten consecutive patients with HCV (hepatitis C virus)-related cirrhosis who underwent liver surgical resection for hepatocellular carcinoma were treated with adjuvant injection of 131-iodine-labeled lipiodol. They were matched with 20 HCV-positive cirrhotic controls who underwent liver resection alone; patients were paired in terms of age, Child-Pugh class, tumor size, microscopic vascular invasion, tumor histological pattern, presence of satellite nodules and type of surgical resection. Recurrence was defined as the development of a new hypervascularizated nodule in the liver. RESULTS: No significant differences were found between the two groups in clinical, biologic and histologic characteristics, except a lower platelet count in the control group. None of the treated patients developed an intrahepatic recurrence until the 15th month from liver resection, whereas recurrences occurred in nine of the 20 patients in the control group (p=0.01). From 18 months onwards, recurrences appeared also in the treated patients, and after 36 months of follow-up both recurrence rate and overall survival were not significantly different between the two groups. CONCLUSIONS: Intrahepatic injection of 131-iodine-labeled lipiodol improves the disease-free survival rate following liver resection of hepatocellular carcinoma in the short term up to 15 months; this advantage fades, however, away after 36 months.

Randomized clinical trial of liver resection with and without hepatic pedicle clamping.
BACKGROUND: The purpose of this study was to compare the perioperative outcome of liver resection with and without intermittent hepatic pedicle clamping. METHODS: Between June 2002 and June 2004, 126 consecutive patients with resectable liver tumours were randomized to undergo resection with (63 patients) or without (63 patients) intermittent hepatic pedicle clamping. RESULTS: The transection time was significantly higher in the group without hepatic pedicle clamping. The blood loss per cm(2) was similar in the two groups: 2.7 ml/cm(2) in the group with versus 3.2 ml/cm(2) in group without hepatic pedicle clamping (P = 0.425). In the subset of patients with an abnormal liver, there were no differences in blood loss per transection surface: 3.1 ml/cm(2) in the group with versus 2.9 ml/cm(2) in the group without clamping (P = 0.829). The rate of blood transfusions was not higher in the non-clamping group. No differences were observed in the postoperative liver enzyme serum levels, the in-hospital mortality (one patient in each group) or the number of complications. CONCLUSION: This study showed clearly that liver resection without hepatic pedicle clamping is safe, even in patients with a diseased liver.

Cryptosporidium outbreak linked to interactive water feature, UK: importance of guidelines.
A need for national guidelines relating to interactive water features was highlighted following three outbreaks of cryptosporidiosis in the United Kingdom, all of which were related to public water features. In August 2003 the Health Protection Agency South West of England was notified of an outbreak of cryptosporidiosis associated with an interactive water feature designed for water play within an adventure park. The water feature was implicated following samples with a high coliform count and the presence of faecal coliforms. A case was defined as any child (younger than 16 years of age) who had visited the park during August and who subsequently had gastrointestinal symptoms and a faecal sample positive for cryptosporidium. Seventy one children were identified in the cohort. This outbreak of cryptosporidiosis was characterised by a very high attack rate (89%), relatively severe in duration (median 8 days) and had a relatively high hospital admission (16% of cases). The epidemic curve was consistent with a point source of infection, which corresponded to the date 80% of the cohort visited the park. This outbreak has similarities to two other cryptosporidiosis outbreaks reported in England in 2003 that involved public water features. These outbreaks raise issues about the operation and maintenance of water-based recreational attractions that very often involve children. The paper reflects on the basic control measures that can be taken and highlights the need for guidelines, especially since such attractions are becoming increasingly common. The Pool Water Treatment Advisory Group in United Kingdom has now produced guidelines.

First measurement of the transverse spin asymmetries of the deuteron in semi-inclusive deep inelastic scattering.
First measurements of the Collins and Sivers asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarized 6LiD target are presented. The data were taken in 2002 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c. The Collins asymmetry turns out to be compatible with zero, as does the measured Sivers asymmetry within the present statistical errors.

Clinical and pharmacokinetic phase II study of pegylated liposomal doxorubicin and vinorelbine in heavily pretreated recurrent ovarian carcinoma.
BACKGROUND: This multicenter phase II study evaluated feasibility, clinical efficacy, toxicity and pharmacokinetics of the combination of pegylated liposomal doxorubicin (PLD) and vinorelbine (VNR) in patients with platinum-paclitaxel pretreated recurrent ovarian cancer. PATIENTS AND METHODS: All patients received prior treatment with platinum and paclitaxel. Thirty-two heavily pretreated (median number of chemotherapy regimens two, range one to six) ovarian cancer patients received treatment with PLD 30 mg/m(2) and VNR 30 mg/m(2) every three weeks for six cycles. Ten patients entered the pharmacokinetic study, five receiving the PLD-VNR and five the VNR-PLD sequence. RESULTS: In 30 patients evaluated for response and toxicity, the overall response rate was 37% and 10% of patients achieved stable disease. Median time to progression and overall survival were 5.5 months (range 1-10) and 9 months (range 2-16), respectively. Toxicity was generally mild and reversible. VNR AUC(tot) and plasma levels were considerably higher in the PLD-VNR sequence. CONCLUSIONS: The PLD-VNR regimen exhibits significant activity in heavily pretreated patients, is well tolerated and is associated with encouraging survival. Preliminary pharmacokinetic results suggest the PLD-VNR sequence for further clinical applications. This regimen should be considered as a treatment option in patients with chemotherapy-resistant ovarian cancer.

Laparoscopic identification of pelvic nerves in patients with deep infiltrating endometriosis.
BACKGROUND: Nerve sparing is suggested for cancer surgery, but no experience is available for deep endometriosis. The aim of this study was to laparoscopically identify the pelvic nerves in the posterior pelvis. METHODS: A total of 24 patients operated for deep endometriosis were considered. During surgery and on videotapes of the procedures, we evaluated single- or double-sided resection of the uterosacral ligaments and other structure's visualization of the inferior hypogastric and the splanchnic nerves. The most important objective criteria for resection of the nerves was urinary retention after surgery, which was compared to surgical resection on the videotapes. RESULTS: Visualization of the inferior hypogastric nerves was possible in 20 of 22 patients (90.1%). Eight of the 24 patients had at least one inferior hypogastric nerve resected (33.3%). In seven patients (29.2%) resection of the uterosacral ligaments was bilateral, and in three of these the nerves were resected. Postoperatively, the median residual urine volume after the first spontaneous voiding was 40 ml (range, 20-400). Seven of eight patients (29.2%) with resection of the nerves had urinary retention and self-catheterization at discharge. The difference in urinary residuum after first voiding between patients undergoing self-catheterization and patients released without the catheter was significant ( p < 0.01). The median time to resume the voiding function in patients with self-catheterization was 18 days (range, 9-45). CONCLUSIONS: Nerve visualization is possible by means of laparoscopic surgery for deep endometriosis in a high rate of patients. Careful technique is necessary, but the laparoscopic approach may help. Even single-sided radical dissection can induce important urinary retention.

Neuronal cytoskeletal alterations in an experimental model of depression.
It has been proposed that depression is associated with hippocampal morphological changes. The apical dendrite atrophy of hippocampal CA3 pyramidal neurons has been described in experimental models of depression. The aim of the present study was to determine which cytoskeletal components are involved in the morphological changes previously described in the hippocampus of depressed animals. The expression of different neuronal cytoskeletal markers was analyzed by immunohistochemistry in rats exposed to a learned helplessness paradigm, an experimental model of depression. Rats were trained with 60 inescapable foot shocks (0.6 mA/15 s) and escape latencies and failures were tested 4 days after training. Animals in which learned helplessness behavior persisted for 21 days were included in the depressed group. No foot shocks were delivered to control rats. Microtubule-associated protein 2 (MAP-2) and light (NFL; 68 kDa), medium (NFM; 160 kDa) and heavy (NFH; 200 kDa) neurofilament subunit immunostainings were analyzed employing morphometric parameters. In the depressed group, NFL immunostaining decreased 55% (P<0.05) and 60% (P<0.001) in CA3 and dentate gyrus, respectively. In the same areas, MAP-2, NFM and NFH immunostainings did not differ between depressed and control animals. Since NFL is present in the core of mature neurofilament, it is proposed that hippocampal depression-associated plastic alterations may be due to changes in the dynamics of the neurofilament assembly.

Rehabilitative residential treatment in patients with severe mental disorders: personality features associated with short-term outcome.
The aims of this study were to evaluate the outcome of inpatients with severe psychiatric disorders after 6 months of multimodal residential treatment. Ninety-one subjects admitted to residential prolonged treatment at an Italian rehabilitative complex were included in the study. Within 6 months, the program of treatment was effective in reducing symptoms and improving the patients' psychosocial functioning. The study of personality can be useful to "dose" symptomatic (pharmacological and psychotherapeutic) and rehabilitative treatments in the therapy program.

Adaptive changes in the rat hippocampal glutamatergic neurotransmission are observed during long-term treatment with lorazepam.
RATIONALE: Chronic treatment with benzodiazepines induces tolerance to most of their pharmacological effects. The best-studied neurochemical correlation to this phenomenon involves GABAergic adaptive changes. However, some compensation by excitatory neurotransmission could also be postulated. OBJECTIVE: The aim of this work was to investigate the effect of chronic treatment with benzodiazepines on several parameters of hippocampal glutamatergic neurotransmission. METHODS: Rats were injected (IP) with a single dose or daily doses (21 days) of 1 mg/kg lorazepam (LZ) or vehicle. Thirty minutes after the last dose, animals were killed and parameters were measured in the dissected hippocampi. We determined one presynaptic parameter, in vitro glutamate release induced by a 60 mM K(+) stimulus. [(3)H]MK-801 binding to postsynaptic NMDA receptors and the NMDA-stimulated efflux of cGMP were also evaluated. RESULTS: While no changes were observed in any of the parameters after a single dose of the drug, we found an increase of 206% in in vitro glutamate release in chronically treated animals [two-way ANOVA: F(1,16)=6.22], together with an increment of 103% in the NMDA-stimulated cGMP efflux [two-way ANOVA: F(1,18)=14.05]. No changes either in K(D) or in B(max) values for [(3)H]MK-801 binding to hippocampal membranes were observed. CONCLUSIONS: Taken together, these changes strongly suggest that a compensatory increase in the glutamatergic response develops in the hippocampus during chronic treatment with LZ. Our findings might indicate a contribution of glutamatergic mechanisms to the tolerance to hippocampal-mediated effects of LZ, such as amnesic and anticonvulsant activities.

Prospective randomized study of steroids in the prevention of ischaemic injury during hepatic resection with pedicle clamping.
BACKGROUND: The major drawback of hepatic pedicle clamping is ischaemia-reperfusion injury with impairment of liver function. Perioperative steroid administration has been advocated to reduce liver damage. The aim of this prospective, randomized study was to determine whether steroid administration can reduce liver injury and improve short-term outcome. METHODS: Fifty-three patients undergoing liver resection were randomized to a steroid group (group 1) or to a control group (group 2); patients in group 1 received methylprednisolone 30 mg/kg 30 min before liver resection whereas those in group 2 did not. Serum levels of interleukin (IL) 6, total bilirubin, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and prothrombin time (PT) were measured. Length of stay, and type and number of complications were recorded. RESULTS: Serum IL-6 levels were significantly lower in the steroid group than in the control group 24 h after surgery. Steroid administration significantly modified AST, ALT and PT levels only in patients with chronic liver disease. Overall and lung-related morbidity were not significantly different between the two groups. CONCLUSIONS: Steroid administration suppresses serum IL-6 levels, but has no effect on short-term outcome.

Malignant struma ovarii: a case report of laparoscopic management.
BACKGROUND: Struma ovarii is a rare disease. Malignant transformation is even rarer. Data about its management are lacking. We describe the first reported case of a malignant struma ovarii treated and staged by laparoscopy. CASE: A 49-year-old patient was operated by laparoscopy for a right ovarian teratoma. The patient did not show symptoms of hyperthyroidism. The ovarian teratoma was removed in a plastic bag and definitive histology showed foci of papillary adenocarcinoma in a struma ovarii. The patient was then staged by laparoscopic surgery undergoing left adnexectomy, multiple peritoneal and omental biopsies, and common iliac and paracaval lymph node sampling. Hysterectomy was not performed. The postoperative course was uneventful and the patient was released on the second day. Thyroglobulin level was monitored and the patient is free of disease after more than 1 year. CONCLUSION: The preoperative diagnosis of malignant struma ovarii is difficult. Even with cautious evaluation of the patient, some risk of wrong diagnosis is possible. This is why a meticulous technique of laparoscopic surgery in removing the ovary is important. Laparoscopic staging may also intervene in very limited cases; the expertise to perform open staging of the patient is necessary but the postoperative course is fast.

The role of the French-Italian glossary of complications in the outcome evaluation of cervical cancer treatment: an Italian multicentric study.
UNLABELLED: The optimal treatment for cervical cancer is still a controversial matter: in the last two decades a lot of different modalities combining surgery, radiotherapy (RT) and chemotherapy (CHT) have been suggested and analysed in clinical trials. Nevertheless, analysis of treatment in cancer patients should be directed not only to survival, but also to the cost of complications and quality of life. In June 1988, a French-Italian co-operative group set up a glossary in which the complications of the treatment of cervical cancer are described and ranked. Nowadays, this is the only international system based upon an accurate description of symptoms and signs of complications following multidisciplinary treatment. The glossary was based on our previous experience in treating patients by surgery alone, RT or their combinations. Recently multimodality treatment includes also CHT. The aim of the present study was to verify whether the glossary is still a useful clinical instrument in outcome evaluation of cervical cancer treatment. MATERIALS AND METHODS: The analysis has been done on a retrospective consecutive series of 579 patients affected by cervical cancer, treated in five Italian institutions. A minimum of 12 months follow up was required. All medical records of the patients enrolled, were examined by two independent reviewers in order to classify the complications according to the glossary. RESULTS: Out of 579 patients 319 (55.1%) were free of complications and 260 (44.9%) experienced at least one complication. We found 436 complications. The distribution by Grade was: G1 58.9%, G2 27.5%, G3 13.5%. We had no fatal complication (G4). The glossary included all observed complications, except for pulmonary fibrosis. CONCLUSION: The glossary is still a useful instrument in evaluating the outcome of cervical cancer treatment, whatever the therapy, and should be considered in quality of life assessment.

The clinical outcome of patients with stage Ia1 and Ia2 squamous cell carcinoma of the uterine cervix: a Cooperation Task Force (CTF) study.
PURPOSE OF INVESTIGATION: The objective of this retrospective multicenter study was to assess the clinical outcome of patients with microinvasive squamous cell carcinoma of the uterine cervix. METHODS: The hospital records of 166 patients with microinvasive squamous cell carcinoma of the uterine cervix were reviewed. All cases were retrospectively staged according the 1994 International Federation of Gynecology and Obstetrics (FIGO) nomenclature. One hundred and forty-three cases were in Stage Ia1 and 23 in Stage Ia2 disease. Surgery consisted of conization alone in 30 (18.1%) patients, total hysterectomy in 82 (49.4%), and radical hysterectomy in 54 (32.5%). All patients in whom conization was the definite treatment had Stage Ia1 disease and had cone margins negative for intraepithelial or invasive lesions. RESULTS: None of the 67 patients submitted to pelvic lymphadenectomy had histologically proven metastatic lymph nodes. Of the 166 patients, eight (4.8%) had an intraepithelial recurrence and four (2.4%) had an invasive recurrence. With regard to FIGO substage, disease recurred in nine (6.3%) out of 143 patients with Stage Ia1 and three (13.0%) out of 23 with Stage Ia2 cervical cancer. With regard to type of surgery, disease recurred in three (10.0%) out of the patients treated with conization alone, four (4.9%) out those who underwent total hysterectomy, and five (9.3%) out of those who underwent radical hysterectomy. It is worth noting that none of the 30 patients treated with conization alone had recurrent invasive cancer after a median follow-up of 45 months. However three (10%) of these patients developed a cervical intraepithelial neoplasia (CIN) III after 16, 33, and 94 months, respectively, from conization. CONCLUSIONS: Conization can represent the definite treatment for patients with Stage Ia1 squamous cell cervical cancer, if cone margins and apex are disease-free. For patients with Stage Ia2 cervical cancer extrafascial hysterectomy with pelvic lymphadenectomy might be an adequate standard therapy, although the need for lymph node dissection is questionable.

Rho(0) meson production in the pp-->pppi(+)pi(-) reaction at 3.67 GeV/c.
Total and differential cross sections for the exclusive reaction pp-->pp rho observed via the pi(+)pi(-) decay channel have been measured at p(beam)=3.67 GeV/c. The observed total meson production cross section is determined to be (23.4+/-0.8+/-8) mu b and is significantly lower than typical cross sections used in model calculations for heavy-ion collisions. The differential cross sections measured indicate a strong anisotropy (approximately cos(theta(CM)(rho)) in the rho(0) meson production.

Different types of hysterectomy in the radio-surgical treatment of early cervical cancer (FIGO Ib-IIa).
PURPOSE OF INVESTIGATION: Surgery and radiotherapy achieved equivalent results for FIGO stages Ib-IIa invasive cervical carcinoma. The integration of radiotherapy and surgery provided the same results for a selected series of patients without increasing the rate of complications. The aim of the study was to verify if, applying a radio-surgical protocol, the reduction of the surgery extension on the parametrium in one of two consecutive series might achieve the same results in terms of survival and recurrence rates with fewer complications. MATERIAL AND METHODS: We analysed actuarial survival (with >10-year follow-up), local control rates and morbidity of 390 patients who had different the kinds of surgery applied in the radio-surgical treatment protocol: Protocol A: brachytherapy plus type III radical hysterectomy vs Protocol B: brachytherapy plus type II radical hysterectomy. Patients were all included in an analysis of complications according to the French-Italian glossary. RESULTS: Analyses showed no differences in terms of survival, patterns of recurrences and onset time within the two protocols. Urinary complications were more frequent and severe in protocol A vs protocol B (G2: 26.5% vs. 6.1%; G3: 5.3% vs. 3.6%). CONCLUSION: Our study pointed out that the reduction of the surgery extension allowed the same overall survival and relapses with fewer complications particularly in terms of grade of severity.

Repeat hepatectomy for colorectal liver metastases: A worthwhile operation?
BACKGROUND AND OBJECTIVES: After curative resection of hepatic colorectal metastases, 10-20% of patients experience a resectable hepatic recurrence. We wanted to assess the expected risk-to-benefit ratio in comparison to first hepatectomy and to determine the prognostic factors associated with survival. METHODS: Twenty-nine patients from a group of 152 patients resected for colorectal liver metastases underwent 32 repeat hepatectomies. RESULTS: In-hospital mortality was 3.5% (1/29 patients); the morbidity after repeat hepatectomy was lower than that after first hepatic resection. Combined extrahepatic surgery was performed on 34.5% of repeat hepatectomies vs. 6.9% of first hepatectomies (P = 0.01). Overall actuarial 3-year survival was 35.1%: four patients have survived more than 3 years and one survived for more than 5 years. The number of hepatic metastases and the carcinoembryonic antigen (CEA) serum levels were significant prognostic factors on univariate analysis. The synchronous resection of hepatic and extrahepatic disease was not associated with a lower survival rate when compared with that of patients without extrahepatic localization: three patients of the former group are alive and disease-free at more than 2 years. CONCLUSIONS: Repeat hepatic resection can provide long-term survival rates similar to those of first liver resection, with comparable mortality and morbidity. The presence of resectable extrahepatic disease must not be an absolute contraindication to synchronous hepatectomy because long-term survival is possible.
