Outcomes of Abdominoplasty in Tumescent Local Anesthesia Combined with Subdural Anesthesia.

BACKGROUND: Abdominoplasty is a common surgical procedure performed under general anesthesia, and although the use of TLA combined with subdural anesthesia has never been reported in abdominoplasty, it offers several benefits such as safe and effective local anesthesia and vasoconstriction. We outline our experience with the TLA technique for primary abdominoplasty over the last 7 years. METHODS: From 2014 to 2021, TLA and subdural anesthesia have been used in primary abdominoplasty surgeries for 106 patients. The TLA solution consisted of 25 mL of 2% lidocaine, 8 mEq of sodium bicarbonate, and 1 mL of epinephrine (1 mg/1 mL) diluted in 1000 mL of 0.9% saline solution. The solution was then injected with a 2-mm cannula into the subcutaneous adipose tissue in the suprafascial plane. The subdural anesthesia was performed at intervertebral level L1-L2 using Ropivacaine 15/18 mg in 4 ml. RESULTS: Patients aged from 32 to 75 years. The amount of tumescent solution infiltrated ranged between 500 and 1000 mL. Mean surgery time was 70 minutes, and recovery room time averaged at 240 minutes. Major complications related to the surgery were observed in 12.26% of patients, including eight hematomas and five seromas. Two patients experienced wound dehiscence, and no dystrophic scar formation was observed. Eventually, there was no need for a conversion to general anesthesia. CONCLUSIONS: Tumescent local anesthesia combined with subdural anesthesia is a highly effective and safe method for performing abdominoplasty. This technique has proven to be an excellent choice for primary abdominoplasty, providing significant benefits to patients and surgeons alike due to its safe administration, precise pain management during and after surgery, and minimal postoperative side effects.

One-Stage Immediate Alloplastic Breast Reconstruction in Large and Ptotic Breasts: An Institutional Algorithm.

Immediate implant-based breast reconstruction in patients with large and ptotic breasts may be challenging due to skin redundancy. The use of a reduction mammoplasty pattern for the mastectomy skin excision has proven to be a reliable option for these patients as it allows for a better shape, projection, and symmetrization. This approach has been described in the literature for both one- and two-stage reconstruction with either sub- or pre-pectoral reconstruction with an acellular dermal matrix (ADM) or non-biological mesh. One-stage immediate breast reconstructions have a positive significant impact on patients' psychosocial well-being and quality of life. The purpose of this paper is to describe an institutional algorithm that allows one to perform one-stage implant-based breast reconstructions in patients with large and ptotic breasts.

HLA-DQ Genotyping, Duodenal Histology, and Response to Exclusion Diet in Autistic Children With Gastrointestinal Symptoms.

OBJECTIVES: A correlation between autism spectrum disorders (ASDs) and gastrointestinal (GI) problems, and a possible link between gluten consumption and ASD have been increasingly reported. Gluten/casein-free diet (GCFD) is often undertaken, with conflicting results. This study aimed at evaluating the distribution of human leukocyte antigen (HLA)-DQ2/DQ8 typing among patients with ASD with GI symptoms, together with its correlation with duodenal histology and response to GCFD. METHODS: Between 2002 and 2015 all patients with ASD with GI symptoms referred to our outpatient clinic, displaying clinical, laboratory, or ultrasound findings suggestive of organic disease, underwent endoscopy, celiac disease (CD) serum antibodies testing and HLA-DQ2/DQ8 genotyping. Patients were prescribed a 6-month GCFD, and then clinically reassessed. RESULTS: Among 151 enrolled patients, 134 (89%) were negative for CD-specific antibodies; 72 (48%) were positive for HLA-DQ2/DQ8; and 56 (37%) showed duodenal microscopic inflammation. Clinical improvement was observed in non-CD patients irrespective of the rigorous or partial adherence to the diet, being the difference nonstatistically significant. Response to diet was related to the presence of histological duodenal alterations at baseline (odds ratio 11.323, 95% confidence interval 1.386-92.549 for Marsh 2 pattern), but not to HLA-DQ2/DQ8 positivity (odds ratio 1.120, 95% confidence interval 0.462-2.716). CONCLUSIONS: Our data suggest that children with ASD with GI symptoms have a high prevalence of duodenal intraepithelial lymphocytic infiltration, which seems to be linked to a mechanism other than autoimmune response to gluten consumption. Alteration of duodenal histology, but not the HLA-DQ2/DQ8 status, was associated with clinical response to the diet.

Non-Alcoholic Fatty Liver Disease and Extra-Hepatic Cancers.

Non-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease but the second cause of death among NAFLD patients are attributed to malignancies at both gastrointestinal (liver, colon, esophagus, stomach, and pancreas) and extra-intestinal sites (kidney in men, and breast in women). Obesity and related metabolic abnormalities are associated with increased incidence or mortality for a number of cancers. NAFLD has an intertwined relationship with metabolic syndrome and significantly contributes to the risk of hepatocellular carcinoma (HCC), but recent evidence have fuelled concerns that NAFLD may be a new, and added, risk factor for extra-hepatic cancers, particularly in the gastrointestinal tract. In this review we critically appraise key studies on NAFLD-associated extra-hepatic cancers and speculate on how NAFLD may influence carcinogenesis at these sites.

Homozygous familial hypercholesterolemia in childhood: Genotype-phenotype description, established therapies and perspectives.

Familial hypercholesterolemia (FH) is a co-dominantly inherited disorder of plasma lipoprotein metabolism. The prevalence of heterozygous FH (HeFH) is between 1/500 and 1/200 whereas that of homozygous form (HoFH) is about 1/1,000,000. Diagnosis is based on cutaneous xanthomas and untreated levels of LDL-cholesterol over 500 mg/dl before 10 years of age. Life expectancy, without treatment, does not exceed 20 years of age. The aim of this study is to characterise in details a cohort of 8 HoFH paediatric patients in order to illustrate all the current therapeutic options and to add some clinical and genetic information about this rare disease. We collected demographic, clinical, biological, imaging and genotype details. Furthermore, clinical and biochemical response to different treatment methods was retrospectively evaluated. All patients had genetically proven HoFH. All patients were subject to a lipid-lowering diet and medical treatment (except one), three patients underwent a liver transplant and one an hepatocytes infusion. Medical treatment was well tolerated with a median reduction of 44% and 47% in LDL-Cholesterol and Total Cholesterol respectively. The hepatocytes transplant produced a further, though slight, decrease in cholesterol levels as opposed to medical therapy alone. Transplanted patients normalized their cholesterol levels. Since the very high cardiovascular risk, HoFH requires immediate diagnosis, treatment and monitoring. Nowadays, the use of statins remains the cornerstone of medical therapy and liver transplantation is the possibly curative therapy. Besides, high hopes are pinned in new drugs (antibody targeting PCSK9, Mipomersen and Lomitapide) and stem cells.

Clinical impact of A/H1/N1/09 influenza in patients with cirrhosis: experience from a nosocomial cluster of infection.

A/H1N1/09 influenza is associated with a high risk of complications in patients with chronic diseases, but data on morbidity and mortality in patients with cirrhosis are limited. A cluster of A/H1N1/09 infection in 48 patients admitted to a Gastro-Hepatology Unit is reported. Nosocomial spread, clinical outcome, and viral characteristics of A/H1N1/09 strains from a study group of 48 inpatients (21 and 27 with and without cirrhosis, respectively) were compared with those from a control group of 44 outpatients with mild influenza-like illness and without cirrhosis. A/H1N1/09 infection was confirmed in 8/48 (17%) inpatients. A/H1N1/09 infection rate did not differ in patients with and without cirrhosis (4/21, 19%; 4/27, 15%), but three patients with cirrhosis died of pneumonia and acute respiratory distress syndrome, with fungal or bacterial superinfection in two cases, despite antiviral treatment. None of patients without cirrhosis died. Viral sequences showed the presence of hemagglutinin mutation D222G in two out of three fatal cases and S183P in seven out of eight infected patients. These mutants were not detected in the outpatients group. Even if A/H1N1/09 infection rate in hospitalized patients with and without cirrhosis was not significantly different, cirrhosis and D222G/S183P substitutions were significantly associated with severe disease and poor outcome, also suggesting fungal or bacterial superinfection and portal hypertension as risk factors for A/H1N1/09 disease severity in patients with cirrhosis. Vaccination, preventive and early treatment and a strict control of nosocomial spread should be activated carefully in patients with cirrhosis during epidemics influenza.

Safety and efficacy of endoscopic retrograde cholangiopancreatography in patients with post-liver transplant biliary complications: results of a cohort study with long-term follow-up.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is the standard approach for the management of biliary complications in liver transplant patients; however, its safety and efficacy have not been established in this setting. This study was performed to evaluate the safety and long-term efficacy of ERCP in transplant patients. METHODS: The case reports of 1,500 liver transplant patients were reviewed. Orthotopic liver transplantation (OLT) patients were matched 1:2 with non-OLT patients and followed-up for long-term outcome (median, 7.4 years). RESULTS: Of the 1,500 liver transplant patients, 94 (6.3%) underwent 150 ERCPs after OLT. Anastomotic strictures were present in 45 patients, biliary stones in 24, biliary leaks in 7, papillary stenosis in 2, and primary sclerosing cholangitis in 1. An ERCP success rate of 90.7% was achieved; biliary stenting led to resolution of the bile leak in 7/7 (100%) patients, and biliary stones were removed in 21/24 (87.5%) patients. In addition, 34 of 45 patients with anastomotic stricture underwent endoscopic dilation. We obtained complete resolution in 22/34 (64.7%) patients. OLT patients did not show a higher probability of complications (odds ratio [OR], 1.04), of pancreatitis (OR, 0.80) or of bleeding (OR, 1.34). CONCLUSIONS: ERCP is safe and effective for the treatment of post-OLT biliary complications, has a low rate of pancreatitis and results in a durable effect.
