No full textIntroduction. Post-Endoscopic Retrograde Cholangio-Pancreatography pancreatitis (PEP) is a relevant (1-4%) complication of biliopancreatic operative endoscopy. Rectal nonsteroidal anti-inflammatory drugs (specifically, 100 mg of diclofenac) have shown promising prophylactic activity in PEP. The aim of our prospective study is to report whether prophylactic oral versus rectal suppository versus intramuscular diclofenac versus placebo are able to reduce the incidence and the severity of ERCP-induced pancreatitis.Materials and Methods. in this randomized, double-blinded, prospective study, 100 patients (49 male, 51 female), similar with regard to indication for ERCP, were enrolled between January 2016 and November 2017 to undergo ERCP in the Section of General and Thoracic Surgery of University Hospital of Palermo. They were randomized into five groups, respectively 20 patients with placebo by mouth; 20 patients with 50 mg diclofenac sodium enteric-coated capsules by mouth; 20 with 100 mg rectal suppository diclofenac, 20 with 75 mg/3 ml intramuscular diclofenac sodium, 20 with 75 mg/3 ml intramuscular diclofenac sodium and 20 with 75 mg/3 ml intravenous diclofenac. All drugs were administered 30 to 90 minutes before ERCP. All clinical data were collected one day before and 2, 12 and 24 hour after ERCP.Results. data were prospectively collected and to demonstrate the preventive effect of rectal diclofenac on PEP, a two-by-two table and chi-square test with Yates correction were used: the incidence of PEP was significantly lower (p < 0.001) in the rectal diclofenac group respect to other groups and, in the same way. the incidence of post-ERCP pain was significantly lower in the rectal diclofenac group than in the other groups (p = 0.001) and patients discharge was consequently earlier (p < 0.01).Conclusions. 100 mg dose rectal diclofenac administered 30-60 minutes before ERCP can effectively prevent PEP
Loup-assisted technique to create arterio-venous fistulas in elderly. A single centre experience
No full textAIMS: The radio-cephalic arteriovenous fistula (RCAVF) is the first choice treatment in end-stage renal disease patients. In the last few years, the hemodialysis population has shown a high percentage of elderly patients (> 65 year old) with comorbidities, mainly vascular diseases, which may adversely affect their vascular access success. The aim of this study was to evaluate the effectiveness of a loup-assisted technique to create RCAVFs in over 65 patients. PATIENTS AND METHODS: 98 consecutive patients with renal failure were prospectively observed. The patient were divided in relation to their age (> 65 year old; < 65 year old). In both groups, a microsurgical distal RCAVF was created. Statistics included the prevalence of distal RCAVF created, the incidence of immediate failure, the primary and secondary patency rate at one year. RESULTS: Distal RCAVF was created in 82.60% of patients younger than 65 years and in 73.07% of patients older than 65 years, with no statistically significant difference. The incidence of immediate failure, the primary and secondary patency at one year were not statistically significant between the two groups. CONCLUSIONS: Distal RCAVF should be the first choice vascular access even in ESRD elderly patients. The loup-assisted microsurgical fistula creation, allows to perform distal RCAVF with success, even in patients older than 65 years old, achieving similar results to younger patients
Abdominal Compartment Syndrome: diagnostic evaluation and possible treatment
No full textBACKGROUND: Abdominal compartment syndrome (ACS) is a clinical condition caused by an increase in intra-abdominal pressure. The incidence is variable, based on the type of patients taken into consideration, increasing exponentially in critical conditions, such as traumatized, burned patients in shock. The syndrome can also follow surgical procedures like transplantation of abdominal organs, for example configuring rare pictures such as RACS (post-transplant kidney syndrome). In most cases the symptoms are non-specific and varied according to the different etiology of the ACS, therefore the diagnosis may not be immediate. AIM: The aim of this work is to evaluate the best therapeutic approach based on the evidence in the literature. RESULTS: An early diagnosis, which can also identify the stages of intra-abdominal hypertension, is necessary to ensure the survival of the patient, implementing an integrated multidisciplinary treatment, expecially in the early stages of the development of the ACS. CONCLUSIONS: The definitive treatment is surgical and is based on the decompression of the abdomen
Remission of an HHV8-related extracavitary primary effusion lymphoma in an HIV-positive patient during antiretroviral treatment containing dolutegravir
No full textBackgroundHuman herpes virus 8 (HHV8) is the causative agent of Kaposi's sarcoma and has been associated with an increasing number of hematologic diseases such as primary effusion lymphoma (PEL) (both classic and extracavitary form), multicentric Castleman disease and the germinotropic lymphoproliferative disorder. PEL is a rare B cell non-Hodgkin lymphoma that primarily affects immunocompromised patients; aggressive chemotherapy and antiretroviral therapy (ART) with protease inhibitors have been used, with poor results. We present a case of extracavitary PEL in an HIV-infected patient, regressed after ART initiation.Case presentationA 42-year-old male was admitted to the emergency room because of several months of malaise, fever and progressive deterioration of the general conditions. On physical examination soft non-painful subcutaneous masses were palpable at retronuchal, retroauricolar and thoracic regions. HIV serology resulted positive: HIV plasma viremia was 782,270 copies/mL, CD4 103 cells/mL. The excision of one of the masses, metabolically active at a positron emission tomography (PET-CT) scan, revealed an HHV8-related extracavitary PEL. HHV8 plasma viremia was 44,826 copies/mL. ART with tenofovir alafenamide/emtricitabine/dolutegravir was started together with ganciclovir for cytomegalovirus chorioretinitis. The progressive disappearance of the masses was seen after 6weeks of ART, and a PET-CT scan resulted completely negative at 3months. After 19months of ART the patient was in remission of PEL, HIV viremia was undetectable (<20 copies/mL), CD4 count was 766 cells/mL and HHV8 viremia was undetectable.ConclusionsIn this clinical case, the complete regression of PEL has been achieved after the immune recovery, as a consequence of ART introduction, without chemotherapy. It cannot be excluded that ganciclovir, used for the treatment of CMV chorioretinitis, may have contributed to the control of HHV8 replication. Whether to try or not a conservative approach in HIV-infected PEL patients must be carefully evaluated, considering the patient's characteristics and the prognostic factors
Hepatitis B reactivation characterized by HBsAg negativity and anti-HbsAg antibodies persistence in haematopoietic stem cell transplanted patient after lamivudine withdrawal
No full textHBV reactivation is associated with high mortality rates in hematopoietic stem cell transplantation (HSCT) and prophylactic lamivudine (LMV) treatment is suggested to prevent this phenomenon. However, the duration of LMV treatment in HSCT patients is not fully defined and the time of immune recovery is considered the best parameter for a drug to be safely interrupted. In patients undergoing allogeneic HSCT, the time of immune recovery is not easy to define and may take years after transplantation and prolonged LMV treatments, which can lead to drug-resistant viral strains

No full textDiagnostic techniques and multidisciplinary approach in idiopathic granulomatous mastitis: A revision of the literature
No full textIdiopathic granulomatous mastitis (IGM) is a chronic benign inflammatory disease of the breast that may mimic breast cancer. It is most common in parous young fertile women, although it can occur in nulliparous women and in men. IGM is an idiopathic disease due to the influence of some environmental factors in genetically predisposed subjects. Several pathogenic hypothesis have been proposed in the last years (autoimmune, hormonal, infective genesis). IGM presents as a painful palpable mass located in one of the two udders. The skin is usually normal but could present signs of inflammation with or without lymph nodes involvement. Ultrasonography, mammography, magnetic resonance can be diagnosed an IGM, but pathog-nomonic radiological signs has not yet reported in literature. Biopsy findings show granulomatous lesion centered on the breast lobule, as in granulomatous mastitis induced by tuberculosis or sarcoidosis. The aim of this review of literature is to verify the development of new advanced diagnostic techniques and multidisciplinary approach for this condition. In the last years innovative approaches have modified IGM diagnosis and therapy, avoiding surgery in most of cases, introducing a more conservative medical approach based on recent etiopathological hypothesis.
