Background:
Laparoscopic sleeve gastrectomy (LSG) causes significant postoperative pain, necessitating effective multimodal analgesia strategies. This study evaluated the efficacy of the external oblique intercostal block (EOIB) in this context.
Methods:
This prospective, randomized, controlled, single-blind study conducted between April and December 2023 included 60 patients who underwent LSG. Patients were divided into the EOIB (30 ml 0.25% bupivacaine/side) and control (no block) groups. The primary outcome was the cumulative intravenous morphine milligram equivalent (MME) consumption in the first 24 h postoperatively. Secondary outcomes included 12-h MME consumption, pain scores, intraoperative remifentanil use, rescue analgesia requirements, time to first analgesic request, nausea/vomiting scores, antiemetic use, and American Pain Society Patient Outcome Questionnaire-Revised Turkish Version (APS-POQ-R-TR) scores.
Results:
The control group had significantly higher median opioid consumption than the EOIB group at 12 (14.4 vs. 5.8 mg; P < 0.001) and 24 h (25.9 vs. 10.6 mg; P < 0.001) postoperatively. The need for rescue analgesics did not differ significantly (43.3 vs. 23.3%; P = 0.1). The EOIB group exhibited significantly higher patient satisfaction (APS-POQ-R-TR score 2.91 vs. 4.42; P < 0.001) and consistently lower pain scores across all time points (P < 0.001). The EOIB group had lower nausea/vomiting scores (P < 0.001), fewer patients requiring antiemetics (16.7% vs. 40%; P = 0.045), longer time to first morphine request (57.5 vs. 25 min; P < 0.001), and lower remifentanil use (850 vs. 1050 μg; P < 0.001).
Conclusions
The preoperative EOIB, as a part of multimodal analgesia, provides effective analgesia for acute pain in patients undergoing LSG.

The hepatitis C virus (HCV) is a blood-borne pathogen that causes acute or chronic infection of the liver, sometimes leading to serious liver damage and fatality. The objective of this study was to evaluate HCV prevalence in patients attending the Regional Training and Research Hospital for Medical Examination and Surgery in Samsun Province of Turkey between 2014 and 2017. Blood specimens taken from 152 596 patients were screened for HCV infection by using the anti-HCV assay. Seropositive samples were subjected to polymerase chain reaction (PCR) testing in order to determine whether the HCV infection was active. Genotyping was then performed. Overall, HCV seropositivity and active HCV infection were 2.76% and 2.05%, respectively. Foreign nationals accounted for 5.61% of the seropositive samples and 1.37% of active HCV infective samples. We further report that 2017 was the year with the highest seroprevalence which was 3.64%. HCV genotype 1 was the most common genotype detected in residents of Samsun Province at 89.86%, followed by Genotype 3 at 4.54%. This study provides important information on the levels of HCV infection in the Samsun region of Turkey. The data indicate that there was a rising trend of HCV infection between 2014 and 2017.

Leishmaniasis causes significant morbidity and mortality worldwide. In our country, there has been a
significant increase in the number of cases of leishmaniasis in the last decade. In our study, the effects
of Hypericum thymbrifolium, Hypericum scabrum and Eryngium creticum plant extracts were tested on
Leishmania major, Leishmania tropica and Leishmania infantum/donovani, which were clinically resistant
by not responding to Glucantime® therapy. Cytotoxicity of these extracts were evaluated by XTT method
in the human fibroblast cell line. Possible active ingredients were detected by GC-MS analysis from plant
extracts. Glucantime® resistance was detected at concentrations of 50 µg/mL and lower in 4 of the 7
strains tested. No living leishmania parasites were found in leishmania strains treated with plant extracts
at concentrations of 100 µg/mL or higher. The concentrations of plant extracts included in the study
on the WI-38 human fibroblast cell line were not cytotoxic. According to the GC-MS analysis, several
active substances with biological activities and anti-parasitic effects, such as Thiophene, Germacrene-D,
trans-Geranylgeraniol, Pyridine, and Maleimides, were identified. Based on the findings of the study, it
is believed that these identified active substances when supported by in-vivo studies, will pave the way
for future research and have the potential to be developed as anti-leishmania drugs.
