Preliminary results about a novel technique of mesh positioning in the abdominal wall hernia repair.

INTRODUCTION: The surgical techniques described to approach the incisional hernia repair are various and there is not consensus about which of them to use. The Intra-Peritoneal Onlay Technique (IPOM) with classic mesh positioning is burdened by high post-operative complication rate. The study shows the preliminary results of a novel technique of open IPOM mesh positioning with "percutaneous" approach. PATIENTS AND METHODS: From January 2010 to December 2016 patients with abdominal wall incisional hernia that underwent surgical operation via open mesh technique for abdominal wall hernia repair at the "Policlinico Paolo Giaccone" at Palermo University Hospital were identified and the data collected were retrospectively reviewed; patients' medical and surgical records were collected from charts and the surgical registries. One hundred thirty-five patients with open IPOM percutaneous mesh positioning were selected. DISCUSSION AND CONCLUSIONS: The observational study proposed showed that the technique described for the abdominal wall incisional hernia repair seems to be hopeful in order to set a post-operative course not burdened by elevated rate of post-operative complications, estimated to be near 37% vs 13% reported by our series.

The abdominal wall incisional hernia repair in cirrhotic patients.

BACKGROUND: The incidence of abdominal wall hernia in cirrhotic patients with ascites is between 20 and 40%. Controversies regarding the treatment modality and surgical timing of abdominal wall incisional hernia repair in cirrhotic patients remain. The study proposed wants to analyze the abdominal incisional hernia repair in cirrhotic patients with ascites performed in a single center to determine post-operative morbidity, mortality and complication rate. PATIENTS AND METHODS: Cirrhotic patients with abdominal incisional hernia that underwent surgical operation for abdominal wall hernia repair at the "Policlinico Paolo Giaccone" at Palermo University Hospital between January 2015 and December 2016 were identified and the data collected were retrospectively reviewed; patients' medical and surgical records were collected from charts and the surgical and ICU registries. The degree of hepatic dysfunction was classified using Child-Pugh classification. Post-operative mortality was considered up to 30-days after surgery. A follow-up period of 6 months at least was performed to evaluate hernia recurrence and complications. RESULTS: Mortality rate is of 18.5% (p 0.002). Recurrence rate (p 0.004) and seroma formation rate (p 0.001) are most frequent in urgency group. The elevated ASA score and the prediction of a complicated post-operative course is higher in urgency group (p 0.004) as higher is the in-hospital stay (p 0.001) and the ICU stay (p 0.001). CONCLUSIONS: Elective surgery for abdominal wall hernia repair in cirrhotic patients seems to be successful and associated with lower mortality/morbidity rate and recurrence rate than urgency.

Multiparametric evaluation of risk factors associated to seroma formation in abdominal wall surgery.

INTRODUCTION: Incisional hernia is one of the main topics in the general surgery since there is not a unanimous consensus concerning to the best surgical methodology to adopt. It seems that prosthetic surgery is the best technique, even if responsible for the development of periprosthetic seroma. The aim of this study is to assess whether the preoperative abnormalities of the bio-humoral parameters may be considered as risk factors for seroma. PATIENTS AND METHODS: From July 2016 to July 2017 at the "Policlinico Paolo Giaccone", Palermo, Department of Emergency Surgery, 56 patients included in this study, underwent laparotomic mesh repair. The inclusion criteria were: age > 18 years, incisional hernia W2R0 according to the Chevrel classification and a monoperator technique. The main variables were: sex, age, BMI, smoke, ASA score, and co-morbidities. Among the main serum-blood variables: natraemia, kalaemia, chloraemia, calcaemia, PCR, level of glucose, creatinine, albumin and proteins in the blood. The data were analyzed using SPSS software. RESULTS: Univariate analysis highlighted hypo- and hyper-natraemia, hyper-kalaemia, hypo-chloraemia, high levels of PCR, hyper-glycemia, low level of serum-blood albumin and proteins, as statistically significant variables. Multivariate analysis revealed a p<0.05 for PCR, hypo-albuminemia and total serum-blood-protein level. CONCLUSIONS: Alterations of pre-operative bio-humoral parameters could be associated to a greater risk of seroma development. A better understanding of such alterations may lead to more efficient risk stratification methods. This could be essential to better address the medical resources, reducing the post-operative complications and the outpatient controls as well as the risk associated to seroma.

Treatment of bulimia nervosa with sertraline: a randomized controlled trial.

Bulimia nervosa (BN) is one of the most frequently encountered eating disorders in industrialized societies. It has been suggested that reduced serotonin activity may trigger some of the cognitive and mood disturbances associated with BN. Thus, pharmacologic treatment of BN is mainly based on the use of selective serotonin reuptake inhibitors, which have proved effective. At present, the biological basis of this disorder is not completely clear. The aim of this randomized, controlled trial was to verify the efficacy of sertraline, a selective serotonin reuptake inhibitor, in a group of patients with a diagnosis of BN. Twenty female outpatients, with an age range of 24 to 36 years and a diagnosis of purging type BN as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM IV), were assigned randomly to two treatment groups. The first group received sertraline 100 mg/day for 12 weeks; the second group received placebo. The study was conducted for 12 weeks, with weekly clinical assessments. At the end of the observation period, the group treated with sertraline had a statistically significant reduction in the number of binge eating crises and purging compared with the group who received placebo. In no case was treatment interrupted because of side effects. This study confirms that sertraline is well tolerated and effective in reducing binge-eating crises and purging in patients with BN.

Reflections on the meaning of care.

Health care is increasingly delivered by using medical technologies and specialized procedures. However, the systems through which it is delivered are coming under attack as lacking in care. Medicine is very capable of treating the human body, but it may be losing its sensitivity towards persons, especially concerning the vulnerability they are experiencing. Nurses are finding that the demands for more efficiency and cost-effective measures do not allow them sufficient time to offer the personal care for which they have always felt responsible. The question of the meaning of care surfaces especially in treating those who are approaching death. The need is to balance the various dimensions of care, keeping its focus on the well-being of persons.

Muscle protein turnover in chronic renal failure patients with metabolic acidosis or normal acid-base balance.

It is currently unknown if metabolic acidosis has any effect on muscle protein metabolism in patients with chronic renal failure (CRF). To address this question, muscle protein turnover was studied in patients with CRF and controls in the postabsorptive state by using the forearm perfusion method together with the 3H-phenylalanine kinetics. Nine patients were acidotic ([HCO-3]a = 20 +/- 0.5 mEq/l) whereas 4 patients had a normal acid-base balance ([HCO-3]a = 25 +/- 0.3 mEq/l). In patients with metabolic acidosis the rates of phenylalanine appearance and disposal from the forearm were increased as compared to controls. Phenylalanine net balance, i.e. net proteolysis, was only slightly higher than in controls. In patients under a normal acid-base balance both rates of appearance and disposal of phenylalanine as well as phenylalanine net balance were similar to controls. These preliminary data suggest that metabolic acidosis can enhance the rate of muscle protein degradation in patients with CRF.

Differential inactivation of three bacteriophages by acid and alkaline pH used in the membrane adsorption-elution method of virus recovery.

The study was prompted by our inability to concentrate phages by a membrane adsorption method effective for polioviruses. Consequently two coliphages WPK and T4, and F116 of Pseudomonas aeruginosa were tested for their resistance to acid (pH 5.2-3.2) and alkaline (pH 10-11.5) exposures. Only T4 proved acid resistant allowing for acid adsorption, and only WPK was sufficiently alkaline resistant to allow for alkaline elution. Thus, the differential susceptibility of various phages precludes the use of the acid membrane adsorption-alkaline elution method as a general method for the concentration of phages from large volumes of water.
