Approximately 20% of hepatocellular carcinomas (HCC) occur in noncirrhotic livers. Resection may be considered for patients with HCC, provided sufficient future liver remnant is available, regardless of the tumor size. Tumors located posteriorly near the right hepatic vein (RHV), or inferior vena cava can be managed through anterior or caudal approaches. RHV is typically conserved during right posterior sectionectomy. When a large posteriorly placed tumor causes chronic compression on RHV, the right anterior section drainage is redirected preferentially to the middle hepatic vein. The division of RHV in such instances does not cause congestion of segments 8 and 5. The technical complexity of laparoscopic right posterior sectionectomy arises from the large transection surface, positioned horizontally. We describe in this multimedia article, a case of large HCC in segments 6 and 7, which was successfully treated using laparoscopic anatomic right posterior sectionectomy.

Median arcuate ligament syndrome (MALS) is a rare condition and a diagnosis of exclusion. We present a 30-year-old man, who had postprandial upper abdominal pain and weight loss of 6 kg in 3 months. His gastroscopy and abdominal ultrasound results were both unremarkable. Computed tomographic angiography showed characteristic compression of the celiac artery by thickened median arcuate ligament causing a ‘J’ shaped course of artery with poststenotic dilatation and dilated branches of the celiac artery. The patient underwent laparoscopic release of the median arcuate ligament. The intraoperative blood loss was 20 mL and duration of the procedure was 140 minutes. The patient had an uneventful recovery and was discharged on postoperative day 2. The symptoms subsided 2 months following surgery and he started gaining weight. Laparoscopic division of the median arcuate ligament is a minimally invasive, safe, and effective method to decompress the celiac artery.

Tongue-lip adhesion in Pierre Robin sequence

Patients with Pierre Robin sequence exhibit varying degrees of airway obstruction and feeding difficulty. In some patients, airway obstruction may be profound, warranting surgical intervention to maintain a patent airway. The purpose of this article is to highlight the advantages of the tongue-lip adhesion procedure for the management of airway obstruction in such patients compared to the currently available options.

Probiotics are live microorganisms which upon ingestion confer health benefits to the host such as prevention of infection in the digestive tract, activate, and modulate the immune response and increase the number of native bacteria in the gut. The present study was aimed to isolate bacteria from donkey dung and characterize for probiotic activity. Bacterial cultures were isolated from excreta of infant donkey and were characterized using standard procedures. Cultures were grown anaerobically, and in total 16 cultures showing Lactobacillus morphology were further screened for the probiotic property. Isolate LB-VII was found to be non-hemolytic and has the ability to tolerate 1.2% bile, pH 1.5~10, 8% NaCl as well as showed growth at 42°C. The culture survived gastric and intestinal environment and showed bile salt hydrolysis activity. LB-VII exhibited 100% auto-aggregation and hydrophobic reaction. The culture could also co-aggregate with Escherichia coli, Enterococcus faecalis, and Staphylococcus aureus, a property, which is required to control pathogens. Moreover, the isolate resist a wide range of antibiotic. All these characters make LB-VII a good probiotic culture and was identified as L. plantarum by molecular methods.

Purified melanin pigment from Klebsiella sp. GSK was characterized by thermogravimetric, differential thermal, X ray diffraction and elemental analysis. This melanin pigment is structurally amorphous in nature. It is thermally stable up to 300oC and emits a strong exothermic peak at 700oC. Its carbon, hydrogen and nitrogen composition is 47.9%, 6.9% and 12.0%, respectively. It was used to scavenge metal ions and free radicals. After immobilizing the pigment and using it to adsorb copper and lead ions, the metal ion adsorption capacity was evaluated by atomic absorption spectroscopy (AAS) and the identity of melanin functional groups involved in the binding of metal ions was determined by Fourier transform infrared (FT-IR) spectroscopy. Batch adsorption studies showed that 169 mg/g of copper and 280 mg/g of lead were adsorbed onto melanin-alginate beads. The metal ion adsorption capacity of the melanin-alginate beads was relatively significant compared to alginate beads. The metal ion desorption capacity of HCl was greater (81.5% and 99% for copper and lead, respectively) than that of EDTA (80% and 71% for copper and lead, respectively). The ability of the melanin pigment to scavenge free radicals was evaluated by inhibition of the oxidation of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2`-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and was shown to be about 74% and 98%, respectively, compared with standard antioxidants.

In vitro evaluation of octenidine as an antimicrobial agent against Staphylococcus epidermidis in disinfecting the root canal system

Objectives: Irrigants are imperative in endodontic therapy for the elimination of pathogens from the infected root canal. The present study compared the antimicrobial efficacy of octenidine dihydrochloride (OCT) with chlorhexidine (CHX) and sodium hypochlorite (NaOCl) against Staphylococcus epidermidis ( S. epidermidis ) for root canal disinfection. Materials and Methods: The minimum inhibitory concentration (MIC) was obtained using serial dilution method. The agar diffusion method was then used to determine the zones of inhibition for each irrigant. Lastly, forty 6-mm dentin blocks were prepared from human mandibular premolars and inoculated with S. epidermidis . Samples were randomly divided into 4 groups of 10 blocks and irrigated for 3 minutes with saline (control), 2% CHX, 3% NaOCl, or 0.1% OCT. Dentin samples were then collected immediately for microbial analysis, including an analysis of colony-forming units (CFUs). Results: The MICs of each tested irrigant were 0.05% for CHX, 0.25% for NaOCl, and 0.0125% for OCT. All tested irrigants showed concentration-dependent increase in zones of inhibition, and 3% NaOCl showed the largest zone of inhibition amongst all tested irrigants ( p < 0.05). There were no significant differences among the CFU measurements of 2% CHX, 3% NaOCl, and 0.1% OCT showing complete elimination of S. epidermidis in all samples. Conclusions: This study showed that OCT was comparable to or even more effective than CHX and NaOCl, demonstrating antimicrobial activity at low concentrations against S. epidermidis .
