BACKGROUND:Pilonidal sinus (PS) is a common disease of the sacrococcygeal-natal region. There are many treatment options, but there is still no consensus on the ideal treatment. We compared the results of our PS patients who were treated with primary...

Background: The present study investigated the effectiveness of platelet-rich plasma (PRP) and mesenchymal stem cells (MSCs) in wound healing suppressed by corticosteroid in rats. Methods: Forty rats were separated into four groups. To disrupt the wound-healing processes, intraperitoneal single dose 10 mg/kg methylprednisolone was administered to all rats with the exception of Sham-S group. Then, full-thickness incision was performed to the abdominal skin of all animals, and PRP or MSCs were applied to the incision line except the Sham-S and Sham-M group animals. Ten days later, all animals were sacrificed to investigate: tissue collagenization, inflammation, and re-epithelialization grades histopathologically; and tissue hydroxyproline (HP), interleukin-1β (IL-1β), tumor necrosis factor-α levels biochemically. Results: Collagenization (p = 0.003) and inflammation grade (p = 0.002) values were higher in PR group. Tissue HP level value was found to be high in MC group (p < 0.001). Tissue IL-1β level value of Sham-M group was lower than those of other groups (p < 0.001). Conclusions: This preliminary study revealed that PRP could improve the histopathological grades in wound healing which was suppressed by corticosteroid in rats, while MSCs could show their therapeutic effects via biochemical route. These positive effects were more salient in PR group.

Purpose: The ratio of c-reactive protein-to-albumin (CRP/Alb) is a biochemical marker of systemic inflammatory response and has been associated with poor survival in cancer. The purpose of this study was to investigate the effect of CRP/Alb ratios on prognosis in gastric cancers. Methods: This study included a retrospective review of a total of 147 patients with locally advanced gastric cancer. Mean platelet volume (MPV) was analyzed statistically to find a prognostic relationship between monocyte/lymphocyte ratio, platelet distribution volume (PDW), MPV/platelet, c-reactive protein/albumin ratio (CAR), and gastric cancer. Patients were staged according to the American Joint Cancer Committee (AJCC) Staging Guidelines. Results: The CRP/Alb ratio was independently associated with overall survival (OS) in patients with gastric cancer (GC). The CAR was above 0.25 in 52.7% (77) of the patients and below 0.25 in 47.3% (69) of the patients. Patients under 0.25 had statistically longer survival rates. Conclusion: A high preoperative CAR value could predict poor prognosis in locally advanced gastric patients. The same predictive value was not observed in other hematological parameters. This simple and cost-effective ratio can be used as a clinically accessible biomarker to assist clinicians in determining future treatment plans.

Background. Transversus abdominis plane (TAP) block is used for postoperative analgesia in laparoscopic cholecystectomy. In laparoscopic cholecystectomy, the incisions are located mainly on the upper right side of the abdomen. Aims. We aim to determine the efficacy of less‐invasive ultrasound‐guided right unilateral oblique subcostal TAP block in laparoscopic cholecystectomy on postoperative analgesia by comparing patients undergoing bilateral TAP block and a control group. Methods. Ninety patients were equally divided into control, unilateral, and bilateral TAP block groups. TAP blocks were conducted before anesthesia. No block was applied to the control group. Patients’ demographics and postoperative pain, satisfaction, and nausea‐vomiting scores and tramadol/ondansetron doses were evaluated. Results. There was no significant difference in the verbal numerical rating scale for pain scores at rest and during coughing (VNRS‐R and VNRS‐C) between unilateral and bilateral TAP block groups at postoperative 1 hour, 2 hour, 4 hour, 8 hour, 12 hour, and 24 hours. In addition, VNRS‐R and VNRS‐C scores were significantly higher in the control group than in the other two groups. Tramadol consumption in the control group was significantly higher than in the unilateral and bilateral TAP block groups (p ≤ 0.01), while no significant difference was identified between unilateral and bilateral TAP block groups (p = 0.303). Nausea‐vomiting scores and ondansetron consumption did not differ significantly between all the groups. Patient satisfaction was significantly higher in unilateral and bilateral groups (p < 0.01, p < 0.01) than in the control group, while there was no significant difference between unilateral and bilateral TAP block groups (p = 0.793). Conclusions. Right unilateral TAP block provides postoperative analgesia as effective as bilateral TAP block in laparoscopic cholecystectomy.

Bezoar is defined as the accumulation of undigested foreign bodies or nutrients in the gastrointestinal tract. These foreign bodies can be hair (trichobezoar), fibers or seeds of vegetables and fruits (phytobezoar), or remnants of milk (lactobezoar) and stones (lithobezoar). Lithobezoar, the accumulation of stones in the digestive tract, is commonly seen in stomach. In this paper, a 7-year-old girl with colonic lithobezoar who presented with constipation, abdominal pain, and the history of pica was successfully treated by the extraction of the stones under general anesthesia.

BACKGROUND:Liver failure is the most feared complication following hepatectomy. Post-hepatectomy liver failure (PHLF) is closely related to the remnant liver volume, and functional reserve. There are several methods for predicting PHLF prior to liver...
