A simplified regimen of targeted antifungal prophylaxis in liver transplant recipients: A single-center experience.

BACKGROUND: Invasive fungal infection (IFI) is a severe complication of liver transplantation burdened by high mortality. Guidelines recommend targeted rather than universal antifungal prophylaxis based on tiers of risk. METHODS: We aimed to evaluate IFI incidence, risk factors, and outcome after implementation of a simplified two-tiered targeted prophylaxis regimen based on a single broad-spectrum antifungal drug (amphotericin B). Patients presenting 1 or more risk factors according to literature were administered prophylaxis. Prospectively collected data on all adult patients transplanted in Turin from January 2011 to December 2015 were reviewed. RESULTS: Patients re-transplanted before postoperative day 7 were considered once, yielding a study cohort of 581 cases. Prophylaxis was administered to 299 (51.4%) patients; adherence to protocol was 94.1%. Sixteen patients developed 18 IFIs for an overall rate of 2.8%. All IFI cases were in targeted prophylaxis group; none of the non-prophylaxis group developed IFI. Most cases (81.3%) presented within 30 days after transplantation during prophylaxis; predominant pathogens were molds (94.4%). Only 1 case of candidemia was observed. One-year mortality in IFI patients was 33.3% vs 6.4% in patients without IFI (P = .001); IFI attributable mortality was 6.3%. At multivariate analysis, significant risk factors for IFI were renal replacement therapy (OR = 8.1) and re-operation (OR = 5.2). CONCLUSIONS: The implementation of a simplified targeted prophylaxis regimen appeared to be safe and applicable and was associated with low IFI incidence and mortality. Association of IFI with re-operation and renal replacement therapy calls for further studies to identify optimal prophylaxis in this subset of patients.

Anterolateral adipofascial turnover flap of the leg: Anatomical study.

AIM: The aim of this study is to clearly define the vascularisation of the lateral paratibial septum of the leg, defining the basis for a vertical pedicled adipofascial flap harvested from the anterolateral aspect of the leg to cover pretibial soft tissue defects. MATERIALS AND METHODS: Twelve cadaver legs (eight fixed with formalin and four fresh) were dissected. The vessels running into the lateral paratibial septum were identified. The number of vessels were noted and evaluated at the lateral border of the proximal, middle and distal thirds of the leg. In addition, an angiographic study was performed on two limbs to confirm the connection between tibialis anterior artery and the overlaying fascia through these septal vessels. RESULTS: All the specimens had periosteo-septal vessels running in the lateral aspect of the tibia. The average number was 6.6. The distribution was constant in all the thirds of the leg. CONCLUSION: These data are useful to propose the harvesting technique for adipofascial flap with vertical pedicle as a suitable reconstructive option to cover pretibial soft tissue defects.

Simultaneous Liver-Kidney Transplantation in Adults: A Single-center Experience Comparing Results With Isolated Liver Transplantation.

BACKGROUND: After introduction of the Model for End-Stage Liver Disease (MELD) score in 2002, a worldwide increasing number of simultaneous liver-kidney transplantations (SLKTx) has been observed. However, organ shortage puts into question the allocation of 2 grafts to 1 recipient. This retrospective, single-center study compared SLKTx results with isolated liver transplantation (LTx). METHODS: Between 1995 and 2013, 37 SLKTx were performed in adult recipients. Every SLKTx was matched by donor age (±5 years) and transplantation date with 2 LTx (n = 74). Pretransplant, intraoperative, and post-transplant variables were collected; liver graft and patient survivals were calculated. RESULTS: As expected, donor age was similar in the 2 groups (median, 39.7 years), whereas serum creatinine level, glomerular filtration rate, and MELD and D-MELD (donor age*MELD) scores were significantly higher in the SLKTx group. SLKTx had longer waiting list time (P = .0034) as well as higher surgical difficulty, testified by more blood transfusions (P = .0083), increased use of classic caval reconstruction (P = .0024), and more frequent need of abdominal packing for bleeding control (P = .0003). In addition, duration of hospital stay (P < .0001), second-look surgery (P = .0082), post-transplant dialysis (P < .0001), and post-transplant infections (P = .04) were significantly greater in SLKTx group. Acute rejection episodes involving the liver were significantly less in SLKTx than in LTx (14% vs 41%; P = .0045). Liver graft and patient survival at 10 years after transplantation was similar in the 2 groups (liver graft: SLKTx, 80% vs LTx, 77% [P = .85]; patient: SLKTx, 86% vs LTx, 79% [P = .56]). CONCLUSIONS: Despite being technically challenging, SLKTx provided excellent long-term results and was shown to be an effective use of liver grafts.

Minimization of anti-hepatitis B surface antigen immunoglobulins for prophylaxis of hepatitis B viral recurrence in the first month after liver transplantation: the meaning of HBsAg quantitative level at the time of transplant.

BACKGROUND: Hepatitis B virus recurrence after liver transplantation (LT) has practically disappeared with a prophylaxis combining anti-hepatitis B surface antigen Immunoglobulins (HBIg) and antiviral drugs. Recently, cost-saving requirements pushed us to move from a fixed schedule of 50,000 IU intravenous HBIg in the first month after LT to an "on demand" administration guided by close monitoring of HBV surface antigen (HBsAg) and anti-HBV surface Antigen antibody (HBsAb) with a serological target of HBsAg negative and HBsAb>300 mIU/mL. In this context, we investigated the meaning of HBsAg quantitative determination at LT in predicting the need of HBIg in the first month after LT. METHODS: From February 2012 to July 2013, we performed 35 LTs in HBsAg-positive patients, 18 of whom had hepatitis Delta virus coinfection (Delta-positive). Anti-HBV prophylaxis was based on nucleos(t)ide analogues from day 1 post-LT and intravenous HBIg (10,000 IU intraoperatively and, in the following days, 5,000 IU and 2,500 IU pulses to reach and maintain the serological target). RESULTS: The HBsAg quantitative level at LT was significantly higher in Delta-positive recipients. Complete negativization of HBsAg and HBsAb serum level>300 mIU/mL was achieved on day 3 in Delta-positive and on day 2 in Delta-negative. A positive linear correlation between HBsAg quantitative level at LT and HBIg administered in the first month after LT was observed (RHO=.788), with a total of 32,500 IU HBIg used in HDV-positive and 22,000 IU in HDV-negative recipients (P=.0016). Compared to the old schedule, we saved a median of 14,750 IU in HDV-positive and 28,000 IU in Delta-negative. No HBV recurrence was observed in a median follow-up of 10.5 months. CONCLUSIONS: Delta-positive patients need higher doses of HBIg to reach the serological target after LT because they have greater HBsAg quantitative levels at LT. In future studies, pre-LT HBsAg quantitative determination will be helpful to predict the actual need of HBIg early after LT.

Should fat graft be recommended in tendon scar treatment? Considerations on three cases (two feet and a severe burned hand).

OBJECTIVES: Lipostructure has been reported as a successful ancillary tool for surgery in tenolysis procedures, but to date no reports of its capability to resolve tendon adherence without further surgery have been reported. The aim of this study is to highlight the role of lipografting in the treatment of tendon and joint adherences. PATIENTS AND METHODS: In our experience, we started treating important tendon adherences together with nerve entrapment on the dorsal aspect of the foot in two cases and in a severe burned hand. RESULTS: We achieved good results both in terms of function and sensory recovery. A twenty four month follow up showed good maintenance of the ROM. We also reported gaining of almost 30-40 degrees of a flexion contracure in the second finger of a burned hand, minimizing further surgery for scar contracture and tenoarthrolysis, with a stable follow up. CONCLUSIONS: We suggest that prior to refer to surgery scars involving tendons as well as joints should be considered for lipografting.

Liver transplantation for hepatocellular carcinoma within Milan Criteria in patients with Model for End-Stage Liver Disease score below 15: the impact of the etiology of cirrhosis on long-term survival.

BACKGROUND: Liver transplantation (OLT) is the gold standard therapy for patients with cirrhosis complicated by hepatocellular carcinoma (HCC) within Milan Criteria (MC). We evaluated the impact of the etiology of the underlying liver disease on long-term outcomes of patients undergoing OLT for HCC within MC having a Model for End-stage Liver Disease (MELD) score < 15. METHODS: From November 2002 to December 2009, we performed 203 primary OLTs from brain-dead donors in recipients with HCC and cirrhosis with biochemical MELD scores below 15. We excluded 31 patients outside MC on the explant pathology of the native liver. The remaining 172 were divided into 3 groups according to the etiology of the underlying cirrhosis: hepatitis C virus-positive (HCV+; n = 78; 45%), hepatitis B virus-positive (HBV+; n = 65; 38%) and other indications (n = 29; 17%). The groups were compared for donor and recipient features, donor-recipient match, and transplant variables. The study endpoint was long-term patient survival. RESULTS: The groups were similar, except for a greater prevalence of hepatitis B core antibody-positive grafts in the HBV+ group and less frequent HCC bridging procedures in the other indications group. After a median follow-up of 72 months, HCC recurrence was observed in 8 (4.7%) patients (6 HCV+, 2 other indications), 5 of whom died. Overall 5-year patient survival of 82%, revealed significant differences among groups: 98.3% in HBV+, 67.1% in HCV+, and 85.8% in other indications (HBV+ vs other indications: P = .01; HBV+ vs HCV+: P = .0001; HCV+ vs other indications: P = NS). In the HCV+ group, recurrent HCV hepatitis was the most frequent cause of death. Upon multivariate analysis, HBV positivity in the recipient was an independent predictor of better patient survival (hazard ratio = 0.10, 95% confidence interval 0.02-0.64, P = .013). CONCLUSIONS: Etiology of the underlying cirrhosis significantly influenced the long-term survival after OLT of patients with HCC within MC and MELD < 15. It should be taken into account in estimation of survival benefit.

The effects of a multimodal training program on burnout syndrome in gynecologic oncology nurses and on the multidisciplinary psychosocial care of gynecologic cancer patients: an Italian experience.

OBJECTIVE: In cancer care, the burden of psycho-emotional elements involved on the patient-healthcare provider relationship cannot be ignored. The aim of this work is to have an impact on the level of burnout experienced by European Institute of Oncology (IEO) gynecologic oncology nurses (N = 14) and on quality of multidisciplinary team work. METHOD: We designed a 12 session multimodal training program consisting of a 1.5 hour theoretical lesson on a specific issue related to gynecologic cancer patient care, 20 minute projection of a short film, and 1.75 hours of role-playing exercises and experiential exchanges. The Link Burnout Questionnaire (Santinello, 2007) was administered before and after the completion of the intervention. We also monitored the number of patients referred to the Psycho-oncology Service as an indicator of the efficacy of the multidisciplinary approach. RESULTS: After the completion of the program, the general level of burnout significantly diminished (p = 0.02); in particular, a significant decrease was observed in the "personal inefficacy" subscale (p = 0.01). The number of patients referred to the Psycho-oncology Service increased by 50%. SIGNIFICANCE OF RESULTS: Nurses are in the first line of those seeing patients through the entire course of the disease. For this reason, they are at a particularly high risk of developing work-related distress. Structured training programs can be a valid answer to work-related distress, and feeling part of a multidisciplinary team helps in providing patients with better psychosocial care.

Outcomes of liver transplantation in simultaneously hepatitis B surface antigen and hepatitis C virus RNA positive recipients: the deleterious effect of donor hepatitis B core antibody positivity.

BACKGROUND: Recent data from Italian studies have shown excellent results of liver transplantation (LT) in hepatitis B virus (HBV)-infected patients with grafts from hepatitis B core antibody (HBcAb)-positive donors, whereas such grafts in hepatitis C virus (HCV)-infected recipients have displayed poorer outcomes. We investigated the results of LT with HBcAb-positive grafts in patients with ongoing HBV and HCV coinfections. METHODS: From August 1999 to December 2009, we performed 27 adult primary LTs from deceased heart-beating donors into recipients showing hepatitis B surface antigen (HBsAg)- and HCV-RNA-positivity simultaneously: 12 patients received a graft from an HBsAg-negative HBcAb-positive donor (core+D group) and 15 from an HBcAb-negative donor (core-D group). Immunosuppression included a calcineurin inhibitor, antimetabolite and steroids which were suspended at 6 months. Anti-HBV prophylaxis was always perfomed with anti-HBs immunoglobulins and nucleos(t)idic analogues. RESULTS: The groups were similar regarding variables of donor, recipient, donor-recipient match, LT procedure, and acute rejection treatment. Median follow-up for surviving grafts was 67 months (range, 16-141). Among all patients, HCV-RNA remained positive after LT. The prevalence of histologically proven recurrent HCV hepatitis was similar in the 2 groups: 83% core+D vs 73% core-D. No recurrent HBV hepatitis occurred during the follow-up. Graft survival at 5 years was significantly lower in the core+D group (core+D 48% vs core-D 87%; P = .018), in which a significantly higher prevalence of graft loss was caused by HCV recurrence (core+D 5/12, 42% vs core-D 1/15, 7%; P = .03). All of the 5 core+D patients who lost their grafts due to HCV recurrence did not receive anti-HCV therapy (4 owing to an aggressive disease and 1 because of patient refusal). CONCLUSIONS: Outcomes of LT in patients with ongoing HBV and HCV coinfection are adversely affected by donor HBcAb positivity, an effect that is mainly mediated by the dismal course of HCV recurrence after LT.

Outcomes of liver transplantation from hepatitis B core antibody-positive donors in viral cirrhosis patients: the prevailing negative effect of recipient hepatitis C virus infection.

BACKGROUND: Liver transplantation (LT) with grafts from hepatitis B core antibody (HBcAb)-positive donors has been the object of recent studies, suggesting different outcomes depending on the etiology of viral cirrhosis in the recipient. METHODS: From November 2002 to December 2009, we transplanted 124 livers from hepatitis B surface antigen (HBsAg)-negative HBcAb-positive deceased heart-beating donors to adult recipients with viral cirrhosis, classified as: HBsAg positive (group 1; n = 63); hepatitis C virus (HCV) RNA positive (group 2; n = 52); and simultaneously HBsAg and HCV-RNA positive (group 3; n = 9). Immunosuppression included a calcineurin inhibitor, mycophenolate, and steroids (tapered to suspension in 6 months). In all groups, anti-HBV prophylaxis was performed with anti-HBs immunoglobulins and nucleos(t)idic analogues. RESULTS: The groups were similar regarding donor, recipient, donor-recipient match, transplant procedure, variables, and treatment of acute rejection, except for younger recipient age in group 1 (P = .009), lower recipient body mass index in group 3 (P = .03), and longer cold ischemia time in group 2 (P = .003). Median follow-up for surviving grafts was 63 (range, 16-102) months. No case of recurrent or de novo hepatitis B occurred. The prevalence of histologically proven recurrent HCV hepatitis was similar in groups 2 and 3 (65% vs 78%). Graft survival at 5 years was 86% in group 1, 35% in group 2, and 31% in group 3 (P < .0001 for group 1 vs 2; P < .01 for group 1 vs 3). On multivariate analysis, independent predictors of worse graft survival were HCV infection in the recipient (HR 8.08, 95% CI 3.36-17.97; P < .0001) and MELD at LT ≥25 (HR 3.72, 95% CI 1.12-12.37; P = .032). CONCLUSIONS: The presence of HCV infection in the recipient is the factor which most negatively influenced the outcome of LT using grafts from HBcAb-positive donors. Allocation of such grafts should consider the type of viral cirrhosis among LT candidates.

θ-burst stimulation of the left hemisphere accelerates recovery of hemispatial neglect.

OBJECTIVE: Cortico-cortical circuits originating from the posterior parietal cortex (PPC) of the intact left hemisphere (LH) may become hyperexcitable in patients with hemispatial neglect due to a right hemispheric (RH) stroke. METHODS: In the current randomized, double-blind, sham-controlled study, we investigated safety and efficacy of continuous theta-burst stimulation (cTBS) in 10 sessions over 2 weeks applied over the intact PPC of the LH in subacute ischemic stroke patients. Severity of neglect was assessed through the standardized Behavioral Inattention Test (BIT). We also measured, by means of bifocal transcranial magnetic stimulation (TMS), how cTBS modified the excitability of the parieto-frontal functional connections in the intact LH. RESULTS: We found that 2 weeks of cTBS, but not sham cTBS, were effective in improving neglect symptoms as measured by BIT score. BIT scores improved by 16.3% after 2 weeks of cTBS and 22.6% at 1 month follow-up. We also found that hyperexcitability of LH parieto-frontal circuits was reduced following treatment with real but not sham cTBS. CONCLUSION: These findings suggest that a 2-week course of cTBS over the LH PPC may be a potential effective strategy in accelerating recovery from visuospatial neglect in subacute stroke patients, possibly counteracting the hyperexcitability of LH parieto-frontal circuits. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that left posterior parietal cortex theta-burst stimulation improves hemispatial neglect for up to 2 weeks after treatment.

Deep Sedation in Paediatric MR: a Review of Our Case Histories.

Sedation in paediatric MR is a necessary choice because very often we are dealing with uncooperative patients about to undergo lengthy examinations. The aim of this a retrospective study is to demonstrate that profound sedation with halogenated vapour Sevorane, together with specific systems for monitoring vital signs, is a safe and reliable technique. In accordance with current guidelines, it is considered essential to have an expert anaesthetist present in order to reduce the risk of incidents, which, in the case of difficulty in the airways, as seen in literature, could have fatal outcomes.

The orbicularis oculi muscle flap: its use for treatment of lagophthalmos and a review of its use for other applications.

BACKGROUND: The management of lagophthalmos in patients with long-standing facial palsy is difficult, since the immobility and scleral show have to be corrected to protect the vision. In this article, the authors describe the treatment of paralytic eye with a static technique using a medially based orbicularis oculi muscle flap (OOMF) from the upper eyelid in patients with lagophthalmos. PATIENTS AND METHODS: From April 2006 to May 2008, five Caucasian patients with ages ranging from 45 to 71 years (mean, 61 years) were treated at the Plastic Surgery Unit of Messina University. All patients underwent orbicularis oculi muscle (OOM) transposition flap to support the lower orbicularis oculi and create a suspension of the eyelid. To validate the anatomical features of the OOM transposition flap, four fresh cadaver heads (eight eyelids) were dissected to demonstrate flap viability, feasibility and suspension effect. RESULTS: We achieved resolution of the lagophthalmos and good cosmetic appearance in all cases. The distance between the upper and lower eyelid points during eye closing (as for sleep) was reduced postoperatively on the paralysed side compared to the contralateral healthy side. Follow-up time ranged from 3 to 25 months (mean, 12 months). All patients healed well with no complications of the flaps. There was no flap contraction, recurrent deformity or significant donor-site morbidity in the follow-up period. The incision scars were almost invisible. CONCLUSIONS: The authors believe that the switching of upper blepharoplasty technique from the upper eyelid to the paralysed and scarred lower lid can be used as a tool to treat lagophthalmos.

External biliary fistula in orthotopic liver transplantation.

During orthotopic liver transplantation (OLT), various situations may occur in which biliary reconstruction is neither technically feasible nor recommended. One bridge to a delayed anastomosis can be an external biliary fistula (EBF). This procedure allows the surgeon to execute hemostatic maneuvers, such as abdominal packing; therefore, biliary reconstruction can be subsequently performed in a bloodless operative field without edematous tissues. EBF can be made by placing in the donor biliary tract a cannula that is fixed to the bile duct using 2-0 silk ties and secured outside the abdominal wall. The biliary anastomosis will be performed within 2 days after the OLT. The aim of this study was to examine the safety of EBF in terms of the incidence of biliary complications compared with a direct anastomosis. Among 1,634 adult OLTs performed in 17 years in our center, 1,322 were carried out with termino-terminal hepaticocholedochostomy (HC-TT); two with side-to-side hepaticocholedochostomy; 208 with hepaticojejunostomy (HJ); 31 with EBF and delayed HC-TT, and 71 with EBF and delayed HJ. Biliary complication rates in the EBF group were 24.5%, including 23.9% in the delayed HJ and 25.8% in the delayed HC-TT. Biliary complication incidence among all OLTs was 24.6% (P = NS). No complications related to the procedure were observed. Therefore, EBF is a safe technique without a higher biliary complication rate. It may be useful when a direct biliary anastomosis is dangerous.

Does nipple preservation in mastectomy improve satisfaction with cosmetic results, psychological adjustment, body image and sexuality?

We investigated the influence of nipple areolar complex (NAC) sparing in mastectomy, on patient satisfaction with cosmetic results, body-image, sexuality and psychological well-being. We developed a specific questionnaire and compared two groups of women who underwent radical mastectomy with immediate breast reconstruction (IBR). Between 2004 and 2006, 310 women with NAC preservation and 143 patients with successive NAC reconstruction were mailed the questionnaire at follow-up 1 year after definitive complete breast reconstruction surgery. 256 questionnaires was available. Our results showed significant differences in favour of the NAC sparing group regarding body image (difficulty in looking at themselves naked and being seen naked by their partners after surgery, P = 0.001 and P = 0.003, respectively); regarding satisfaction with the appearance of the nipple (P < .0001) and with the sensitivity of the nipple (P = 0.001); regarding the feeling of mutilation (P = 0.003). NAC sparing in mastectomy has a positive impact on patient satisfaction, body image and psychological adjustment.

MBL2 and MASP2 gene polymorphisms in patients with hepatocellular carcinoma.

The pathogenesis of hepatocellular carcinoma (HCC) is not fully understood, but the majority of patients with HCC are associated with hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. Mannan-binding lectin (MBL) is a collectin that can act directly as opsonine or activate MBL-associated serine proteases (MASPs) thus initiating the antibody-independent pathway of the complement system. In our study, we analysed two MBL2 and MASP2 functional polymorphisms (MBL2 allele A/0 and MASP2 D120G) as well as MASP2 polymorphism (Y371D) responsible for an amino acidic change in the protein in 215 HCC patients (HBV-infected, HCV-infected, HBV/HCV co-infected and patients with HCC with no viral infection) and 164 healthy controls to give new insights regarding the role of these two molecules in HCC and viral infection pathogenesis. No significant association was found between MBL2 or MASP2 alleles or genotypes, neither comparing the total patients with HCC and healthy controls nor between the different groups of HCC subjects divided for type of viral infection. Also, dividing the total HCC patients group into low MBL producer (A0 and 00 genotypes) and normal producer (AA genotype) and comparing MASP2 polymorphisms in these two groups, no significant differences were found. Our data do not seem to suggest a role for MBL2 and MASP2 polymorphisms in HCC susceptibility either for HBV-HCV infection-dependent HCC or for HCC raised as a consequence of exposure to different risk factors.

Morphological MRI and 3D Myelocisternography MRI in Spontaneous Intracranial Hypotension. A Report of Four Cases.

Spontaneous intracranial hypotension (SIH) is a polyhedric syndrome whose common denominator is postural headache. We describe four cases of spontaneous intracranial hypotension, their clinical-iconographic aspects, and emphasize the use of morphological MRI in the diagnosis and follow-up of this condition. In addition, we propose 3D myelocisternography MRI as a further contribution in cerebrospinal fluid losses causing postural headache.

Preoperative integrated imaging in paediatric cochlear implantation.

Sensorineural hearing loss affects one to two children out of 1000 born apparently healthy and 9% approximately of those born with the risk of different pathologies. The origin of premature deafness is unknown in 25% of children whereas it is genetic in some cases. Prevention and early diagnosis, possibly within six to eight months, aim to avoid deafness becoming a cause of disability. The aim of the present study was to establish the optimal preoperative assessment with a diagnostic imaging protocol involving the integrated use of CT and MRI in the selection of the candidates for cochlear implantation. Twenty children were assessed, divided into three different groups: A) those who had CT only; B) those who had only MR; C) those who had both CT and MRI. The purpose was to estimate diagnostic accuracy in preoperative planning and the role of imaging in the diagnostic protocol for children's deafness. The petrous pyramid was studied with a CT Picker PQ 6000 system to high resolution in the axial and coronal planes, and with an MR Intera Philips 0.5 T device by means of acquisition of sequences B-TFE T2 3D and MIP reconstructions on radial coronal plans. This study was completed successfully for morphological brain MRI examination to complete the diagnosis. The following abnormalities were found in six patients (30%): one case of incomplete partition (Mondini malformation); two cases of vestibular aqueduct enlargement; two cases with anomalous jugular bulb positioning; one case with cochlear ossification. In the remaining 70%: eight patients had no anatomical anomalies; CT and MRI imaging were normal in six patients with minor abnormalities disclosed at surgery (one case of the stapedial artery emerging from the promontory); three anatomical variants of the round window, and two abnormal course of the facial nerve). We emphasize the importance of integrated CT and MRI imaging in the study of children with sensorineural hearing loss. The combination of CT and MRI has been shown to be superior to either modality used alone in view of "risk-free" cochear implantation. High resolution computed tomography and magnetic resonance images obtained by B-TFE T2-weighted 3D sequences help the surgeon in planning the operation and predict operative difficulty and potential complications in paediatric cochlear implant candidates.

Antiprotozoal activity of Brazilian plant extracts from isoquinoline alkaloid-producing families.

Leishmaniasis and Chagas disease afflict the poorest countries in the world. The Brazilian flora represents a rich source for the screening of potential antiparasitic compounds. In this work, we tested the total alkaloid and ethanol extracts of nine different plants from Brazilian families which produce isoquinoline alkaloids, to determine their in vitro antiparasitic effect against L. chagasi and T. cruzi parasites. Promastigotes of L. chagasi were shown to be susceptible only to the total alkaloid extracts of A. crassiflora (EC50 value = 24.89 microg/ml), A. coriacea (EC50 value = 41.60 microg/ml), C. ovalifolia (EC50 value = 63.88 microg/ml) and G. australis (EC50 value = 37.88 microg/ml). Except for the G. australis total alkaloids, all the three extracts presented a considerable activity when tested against intracellular amastigotes. The most effective alkaloid extracts were those from A. crassiflora and C. ovalifolia, which reduced the number of infected macrophages at 25 microg/ml by 86.1% and 89.8%, respectively. Among the 18 tested extracts, 16 showed anti-Trypanosoma activity. Eight extracts (A. crassiflora, A. coriacea, C. ovalifolia, D. furfuracea, D. lanceolata, S. guianensis, X. emarginata and G. australis) were the most effective against the trypomastigotes, killing approximately 100% of the parasites at the maximal concentration of 100 microg/ml. Cytotoxicity against mammalian cells was evaluated for all extracts, but potential ones showed little or no cytotoxicity and a considerable antiparasitic effect, including D. furfuracea, D. lanceolata, G. australis, S. guianensis and X. emarginata. Plants are a rich source of natural compounds, and a powerful tool for the development of new arsenals for the therapy of protozoan diseases.

The orbicularis oculi myocutaneus flap in the repair of the medial canthal region. A new strategy for canthal resurfacing.

The aim of this study was to review the surgical anatomy and the variants of the orbicularis oculi myocutaneus flap (OOMF) for reconstruction of inner canthus defects. Anatomic studies in fresh heads were carried out to demonstrate its blood and nerve supply. Four cases of epitheliomas of the inner canthus were treated with surgical excision and reconstructed with medially based island and nonisland OOMF. A 36-months follow-up showed no deformities of the flap, good colour matching and satisfaction scars. The flap is recommended for small to medium size defects of the inner canthus in patient with skin excess in the eyelid.

[Fournier's gangrene: case report and review of recent literature]. / Malattia di Fournier: caso clinico e revisione della letteratura internazionale recente.

OBJECTIVE: The authors report their experience in diagnosis and treatment of one case of Fournier's gangrene; recent international literature review. EXPERIMENTAL DESIGN: Complete clinical report. Diagnostic, clinical and prognostic indication, evaluation of effectiveness of surgical treatment (debridement and necrosectomy) and follow-up; comparison between indications and multidisciplinary approach proposed by international literature. SETTING: Operative Unit of General and Thoracic Surgery. University "Paolo Giaccone" of Palermo. INTERVENTION: Repeated surgical treatment previous multimodal approach, according to international guide-lines. RESULTS: Complete recovery with "restitutio ad integrum". No relapse were recorded at follow up. CONCLUSIONS: Fournier's gangrene is an uncommon and aggressive synergistic fasciitis of the perineum and genital organs, which may bring the patient to death; it is a true surgical emergency. The disease can no longer be considered to be idiopathic; in most cases a urologic, colorectal or cutaneous source can be identified. Despite antibiotics and aggressive debridement, the mortality rate remains high, particularly in the elderly, in patients with renal failure, and in patients with extensive disease. The presentation is highly variable, necessitating a high index of suspicion. High risk patients include diabetics, alcoholics and debilitated and immunosuppressed individuals. As the AIDS population increases, the incidence of Fournier's gangrene may increase as well. In questionable cases, imaging modalities should be performed to allow early diagnosis and to reduce misses diagnosis. Broad spectrum antibiotics (while waiting for the results of culture and antibiogram effectuated on tissue specimens obtained during necrosectomy) and aggressive debridement remain the hallmarks of treatment. Hyperbaric oxygen therapy and improved local wound care may decrease the extent of tissue destruction. The surgical operation has to be performed in emergency to avoid a rapid spread of tissue necrosis and a possible development towards septic shock. Reconstructive techniques afford better cosmetic results. With early recognition, prompt treatment, improved wound care and reconstructive efforts, the mortality rates and cosmetic results should continue to improve.
