The Prognostic Value of Postoperative Lymph Node Ratio in Gastric Adenocarcinoma Patients Treated With Neoadjuvant Chemotherapy.

Objective In this study, we aimed to investigate the prognostic value of postoperative lymph node ratio (LNR)in locally advanced gastric cancer (GC) patients receiving neoadjuvant chemotherapy (NACT). Methods LNR was calculated as the ratio of positive LNs to the total LNs removed. The receiver operating characteristic (ROC) curve was plotted to estimate the cut-off value of LNR for recurrence.

Early neurological complications in children with classical galactosemia and p.gln188arg mutation.

Background: Despite implementation of a controlled diet, children with classical galactosemia (CG) may develop a variety of developmental and cognitive problems. In this study, we examined the early developmental status of, as well as the neurological and neuroradiological findings for, children with CG.

Methods: We retrospectively evaluated 46 galactosemia patients who were followed between 2003 and 2017.

A comparison of the effects of invasive mechanic ventilation/surfactant therapy and non-invasive nasal-continuous positive airway pressure in preterm newborns.

Aims: This study compared the early-term outcomes of mechanical ventilation (MV)/surfactant treatment with nasal-continuous positive airway pressure (nCPAP) in preterm infants with respiratory distress syndrome (RDS).

Materials And Methods: Data from newborns born between ≥24 and ≤32 weeks of gestation, hospitalized at our newborn intensive care unit, and diagnosed with RDS between January 2009 and February 2012 were analyzed.

Results: Of 193 newborns with RDS who were enrolled in the study, 113 were treated with nCPAP and 80 with MV at a level of 57.

A huge ovarian mucinous cystadenoma causing virilization, preterm labor, and persistent supine hypotensive syndrome during pregnancy.

Mucinous cystadenoma (MC) of the ovary is an unilateral, multilocular cystic benign epithelial tumor. Supposed to be hormone responsive, MC reaches huge sizes during pregnancy. Aortocaval compression is common during pregnancy, especially when the pregnant woman is in the supine position.

The difficulties encountered in conversion from classic pancreaticoduodenectomy to total laparoscopic pancreaticoduodenectomy.

Background: Recently, total laparoscopic pancreatectomy has been performed at many centres as an alternative to open surgery. In this study, we aimed to present the difficulties that we have encountered in converting from classic open pancreaticoduodenectomy to total laparoscopic pancreatectomy.

Materials And Methods: Between December 2012 and January 2014, we had 100 open pancreaticoduodenectomies.

Treatment of open fractures with a computer-assisted external fixator system without the use of fluoroscopy.

Background: Developed for the treatment of deformity correction, computer-assisted circular external fixators in recent years have also been used for fracture fixation. In this study, we aimed to present the efficacy of computer-assisted circular external fixator use in open long bone fractures with our new technique.

Methods: Between February 2013 and June 2014, 14 patients (mean age 24.

A rare reason of the elevated serum Ca 19-9 and Ca 125 levels in neonatal period: Hydrometrocolpos due to distal vaginal atresia.

• Hydrometrocolpos is a rare congenital malformation of the female in neonate. • CA 19-9 and CA 125 are widely used as tumor markers, however several benign conditions are also known to increase levels. • Here we report a newborn with hydrometrocolpos due to distal vaginal atresia and elevated serum CA 19-9 and CA 125 levels.

Pure squamous cell carcinoma of the duodenum.

Primary carcinomas of the small intestine are extremely rare neoplasms. Most of these are adenocarcinomas. Primary squamous cell carcinoma (SCC) of small intestine is exceptionally rare with only occasional case reports in the literature.

Early penile metastasis from primary bladder cancer as the first systemic manifestation: a case report.

Metastatic involement of penis is an exceptionally rare condition. 77% of the metastases are originated from the pelvic region; prostate and bladder are the most frequent primary locations. Retrograde venous route, retrograde lymphatic route, arterial spread, direct extension, implantation and secondary to instrumentation are the mechanisms of metastasis.

Stereolithographic volume evaluation of healing and shaping after rhinoplasty operations.

Nasal edema and volume changes are unavoidable processes during the healing period after rhinoplasty. Various applications were reported regarding the prevention of early edema; however, the literature shows no study focused on the course of the nasal edema and volume changes up-to-date. We aimed to study the nasal volume changes during the first year of postoperative healing period and to form a recovery and volume change diagram with the obtained data.

Lower lip reconstruction with local neuromusculocutaneous advancement flap.

Various reconstruction techniques, using the remaining lip or the adjacent cheek tissue, have been described for the repair of lower lip defects. With these techniques, microstomia, commissural distortion, functional insufficiency, and sensorial loss might be observed. The authors describe a technique of lower lip reconstruction with preservation of neuromuscular tissue as a single-stage procedure.

Pore structure engineering for carbon foams as possible bone implant material.

In this study authors aim to produce carbon foams with controllable pore size and distribution with high ratio of open porosity and to determine the cytotoxicity, and the bio-compatibility of the carbon foams by controlled experiments on the Dawley rats. Carbon foams are produced from Mitsubishi AR pitch at different pressures, temperatures, pressure release times, and additives for the purpose of using it as a bone implant material. Carbon foams with controllable range of pore sizes and distribution by using temperatures between 283 and 300 degrees C, pressures between 38 and 78 bar, and pressure release times between 5 and 600 s.

Simple alternative to the Wright needle in frontalis sling surgery.

The Wright needle is a widely used instrument for insertion of fascia lata or a synthetic material during frontalis suspension surgery; however, difficulties in handling this instrument are frequently encountered by many surgeons. We describe an 18-gauge needle with a 4/0 monofilament polypropylene suture as an alternative to the Wright needle for placement of the sling material in frontalis suspension surgery. Less slippage and easier control of the needle's direction and depth of tissue penetration result in more accurate placement of the material and a reduction in damage to the surrounding tissues.

Implant infection in porous orbital implants.

Purpose: To analyze implant infection in patients with porous orbital implants.

Methods: A retrospective analysis of 212 patients with one of five types of porous orbital implants (bone-derived hydroxyapatite [HA], coralline HA, synthetic HA, porous polyethylene, and aluminium oxide) was conducted. Reasons for surgery, type of surgery, type of implant, peg system used, time of pegging, problems before and after pegging, treatment, and follow-up duration were recorded for all patients, along with additional data including time of onset of infection, microorganism cultured, antibiotics used, patient response to antibiotic therapy, additional interventions, and final status for patients with infection.
