Periprocedural management of antithrombotic therapy and open issues in cancer patients.

Perioperative management of patients who are receiving anticoagulant or antiplatelet drugs and require surgical or invasive procedure is a dilemma for clinicians. The discontinuation exposes the patient to an exceedingly high risk of thromboembolism while there is an exceedingly high bleeding risk if antithrombotic therapy is continued, strictly related to the type of surgery. This complex management is based on the assessment of thromboembolic and bleeding risk. In this review we analyze the strategies to optimize the perioperative use of antithrombotic drugs with special attention to new oral anticoagulant drugs, also in cancer patients.

Anal transitional zone adenocarcinoma following restorative proctocolectomy for ulcerative colitis: case report and review of literature.

Conservative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become the intervention of choice for severe ulcerative colitis (UC) requiring surgery. Sporadically, the occurrence of carcinoma arising in or near the ileo-anal pouch after IPAA for UC has been reported. This issue is of utmost importance as an endoscopic follow-up is mandatory also after the operation. The present paper reports a case of cancer which developed four years after proctocolectomy with IPAA in a young man suffering from UC. Moreover, the authors provide update (PubMed research) by literature review on this issue.

[Role of EUS in a diagnostic and staging algorithm of pancreatic carcinoma: the surgeon point of view]. / Il ruolo dell'EUS in un algoritmo diagnostico-stadiativo del carcinoma pancreatico: il punto di vista del chirurgo.

Survival of pancreatic cancer is improved by surgery and is related to R0 resection. An accurate diagnosis and a careful staging are mandatory. Differential diagnosis must be estabilished between the different pancreatic lesions as carcinoma, chronic pancreatitis, cystic or endocrine neoplasms. Endoscopic ultrasound (EUS) is the best technique for diagnosis and allows cytological examination by fine needle aspiration (FNA). Preoperative resectability is defined by EUS in borderline tumors. EUS is a useful procedure for the surgical strategy of pancreatic cancer.

Serum HCV RNA levels correlate with histological liver damage and concur with steatosis in progression of chronic hepatitis C.

The role of HCV RNA levels and host factors in the severity of liver injury was studied. Enrolled were 298 consecutive liver biopsy-proven chronic hepatitis (CH) C patients (179 men; median age: 52 years, range 19-68; CH, 198; cirrhosis, 100) and 18 chronic hepatitis C with normal ALT. HCV genotypes were: 1a, 4.3%; 1b, 53%; 2a/c, 28%; 3a, 7%; 4, 1.3%, and mixed 6.4%. Serum HCV RNA levels were similar for all genotypes (median: 2.8 x 10(6) eq/ml; range <0.2-69). In patients with chronic hepatitis without cirrhosis, the serum HCV RNA levels reflected the grade of liver necroinflammatory activity (R = 0.45; P < 0.001) and the stage of fibrosis (R = 0.51; P < 0.001), regardless of age, gender, HCV genotype, hepatic steatosis, and hepatic iron overload. Patients with high serum HCV RNA levels (> or =3 x 10(6) eq/ml) had higher ALT values (P < 0.002) than those with lower HCV RNA levels. Patients with normal ALT showed low HCV RNA levels (median: 0.82 x 10(6) eq/ml) and histological features of minimal or mild chronic hepatitis. Cirrhotic patients showed significantly lower levels of viremia than those with chronic hepatitis with a similar HAI. The data of a subgroup of 62 patients with an established time of infection showed that for a similar duration of disease, patients with serum HCV RNA levels > or =3 x 10(6) eq/ml had a significantly higher fibrosis score than those with lower levels. HAI and fibrosis score were significantly higher in patients with HCV RNA levels > or =3 x 10(6) eq/ml and grade 3-4 steatosis than those with lower HCV RNA levels and steatosis grades. The data indicate that the liver damage is correlated with the HCV RNA levels and that a high viral load acts together with steatosis in accelerating the progression of liver injury.

[Postoperative treatment of alcohol withdrawal syndrome in a patient operated for oral cancer]. / Terapia della sindrome da astinenza da alcol nel postoperatorio in paziente trattato chirurgicamente per carcinoma orale.

A case of alcohol withdrawal occurred in a patient affected by cancer of the oral cavity is reported. The patient underwent resection of the floor of the oral cavity, partial glossectomy mandibulectomy and neck dissection; reconstruction was done using microsurgical forearm radial flap. The patient didn't refer his alcohol dependence before operation and withdrawal symptoms with agitation, tachycardia, tachypnea, tremors and vomiting appeared during his postoperative recovery in intensive care where the patient was unable to take any alcohol. A therapeutic plan to use in patients operated for oral cancer with alcohol withdrawal (92% association of oral cancer with alcohol dependence) is reported.

Dual or single hepatitis B and C virus infections in childhood cancer survivors: long-term follow-up and effect of interferon treatment.

We conducted a long-term prospective study of 89 cancer survivor children who had acquired hepatitis B virus (HBV) and/or hepatitis C virus (HCV) during treatment for neoplasia, the aim being to evaluate the natural history of the diseases and the effect of interferon (IFN) treatment. Patients were followed up for a median period of 13 years (range, 8 to 20); 46 were infected by HBV, 11 by HCV, and 32 coinfected by HBV and HCV. A spontaneous clearance of hepatitis B surface antigen (HBsAg) occurred more frequently in coinfected patients (19%) than in the HBV-infected (2%; P =.004), with an annual seroconversion rate of 2.1% and 0.2%, respectively (P =.008). Loss of hepatitis Be antigen (HBeAg) occurred in 44% of coinfected and in 28% of HBV-infected patients. Clearance of serum HCV-RNA was observed in 34% and 9%, respectively, of coinfected and HCV-infected patients. Seventeen HBV-infected, 4 HCV-infected, and 16 coinfected patients received alpha-IFN treatment. In the HBV group, 6 patients (35%) cleared serum HBV DNA and seroconverted to anti-HBe; in the HCV-group, none cleared HCV-RNA. In the coinfected group, 1 patient cleared both HBV DNA and HCV-RNA, 6 patients cleared serum HCV-RNA alone, and 1 only HBV DNA and HBeAg. Overall, the diseases showed a mild histological course with no evidence of liver cirrhosis. A reciprocal interference on viral replication between HBV and HCV may occur in coinfected patients. Treatment seems to be effective for selected cases and is justified in view of the uncertain prognosis of the disease in these patients.

[Syndrome X and microvascular angina]. / Sindrome X ed angina microvascolare.

The term X syndrome is used to indicate a group of patients who present anginous symptoms and ischemic-type electrocardiographic alterations which appear during exercise tolerance tests, dipiridamol tests or Holter's dynamic monitoring where coronary ultrasonography reveals no evident coronary lesions, vasospastic angina, arterial hypertension and/or diabetes mellitus, block of the left branch when resting or exercising, cardiomyopathy or valvulopathy. The highest incidence is in females with a mean age of around 50. A reduced reserve of coronary flow, highlighted both in response to vasodilatators or rapid stimulation and by positron emission tomography (PET), underlies this syndrome. It is thought to be caused by a dysfunction of the coronary microcirculation which consists in a deficit of the endothelium-dependent vasodilatory mechanisms, probably also owing to the accumulation of vasoconstrictive type substances, like endothelin-1. In addition to a dysfunction of the coronary microcirculation, one widely backed hypothesis concerns the existence of an altered perception of painful symptoms in patients with X syndrome: the anomalous constriction of prearteries might cause an increased release of adenosine, able to provoke angina despite the scarce signs of myocardial ischemia in terms of the metabolic or functional profile. From a therapeutic point of view, treatment of these patients is often ineffective: treatment should be based on the use of nitrates, calcium-antagonists or beta-blockers, if necessary moving on to other forms of therapy (aceinhibitors, xanthine methylate, estrogens, alphablockers, imipramine); the simultaneous use of tranquillizers may be useful in view of the anxious personality often characteristic of these patients.
