Antrochoanal polyps (ACPs) are benign polypoid lesions arising from the maxillary antrum and they extend into the choana. They occur more commonly in children and young adults, and they are almost always unilateral. The etiopathogenesis of ACPs is not clear. Nasal obstruction and nasal drainage are the most common presenting symptoms. The differential diagnosis should include the causes of unilateral nasal obstruction. Nasal endoscopy and computed tomography scans are the main diagnostic techniques, and the treatment of ACPs is always surgical. Functional endoscopic sinus surgery (FESS) and powered instrumentation during FESS for complete removal of ACPs are extremely safe and effective procedures. Physicians should focus on detecting the exact origin and extent of the polyp to prevent recurrence.

Epistaxis, active bleeding from the nose, is a common ear nose and throat emergency, and can be severe or even fatal. We report a severe life threatening recurrent massive nasal bleeding caused by intranasal heroin use that has not hitherto been reported in the English literature. A 24-year-old male who took heroin several times nasally presented with massive nasal bleeding. A blood transfusion and an operation to halt nasal bleeding were required. The patient did not experience a bleeding attack 2 months following cessation of nasal heroin use.

PURPOSE: Single incision laparoscopic cholecystectomy (SILC) has become a more frequently performed method for benign gallbladder diseases all over the world. The effects of SILC technique on oxidative stress have not been well documented. The aim of this study was to evaluate the effect of laparoscopic cholecystectomy techniques on systemic oxidative stress by using ischemia modified albumin (IMA). METHODS: In total, 70 patients who had been diagnosed with benign gallbladder pathology were enrolled for this prospective study. Twenty-one patients underwent SILC and 49 patients underwent laparoscopic cholecystectomy (LC). All operations were performed under a standard anesthesia protocol. Serum IMA levels were analysed before operation, 45 minutes and 24 hours after operation. RESULTS: Demographics and preoperative characteristics of the patients were similiar in each group. The mean duration of operation was 37.5 ± 12.5 and 44.6 ± 14.3 minutes in LC and SILC group, respectively. In both groups, there was no statistically significant difference in hospital stay, operative time, or conversion to open surgery. Operative technique did not effect the 45th minute and 24th hour IMA levels. However, prolonged operative time (>30 minutes) caused an early increase in the level of IMA. Twenty-fourth hour IMA levels were not different. CONCLUSION: SILC is an effective and safe surgical prosedure for benign gallbladder diseases. Independent of the surgical technique for cholecystectomy, the prolonged operative time could increase the tissue ischemia.

Clinical and Experimental Vaccine Research 2022;11(1):1-11
Purpose:
Lumpy skin disease (LSD) is a highly contagious and economically important viral infection of cattle, which leads to financial losses in the livestock industry of affected countries. Vaccination is the most effective control measure to prevent the disease. Heterologous sheep pox (SP) vaccine was used against LSD in Turkey. In this research, it was aimed to adapt SP Bakırköy vaccine strain attenuated in lamb kidney cells to Madin-Darby bovine kidney (MDBK) cells to provide better protection than commercial SP vaccine in cattle.
Materials and Methods:
To evaluate safety and efficacy of vaccines, while animals were immunized with 10 doses (104.75 50% tissue culture infectious dose [TCID50]) and 5 doses of SP vaccine (104 TCID50) produced in MDBK cells, others were immunized with commercial Penpox-M vaccine (103.9TCID50). Two cattle were kept as unvaccinated. At day 31 post-vaccination, all animals were challenged with the virulent LSD virus. Blood and swab samples were taken on certain days post-inoculation. Logarithmic differences challenge virus titers between vaccinated and unvaccinated animals were calculated.
Results:
The clinical sign was not observed in animals immunized with 10 doses of SP vaccine. The differences between the animals immunized with SP vaccine and control group was less than log 2.5 and the viremia occurred in immunized animals. The difference in titer was higher than log 2.5 in animals immunized with the Penpox-M, and viremia did not occur.
Conclusion
SP vaccine strain propagated in MDBK cells and can be used for immunization to prevent LSD infections. However, SP vaccine strain propagated in MDBK showed poor protection as compared to Penpox-M.

Objective:
This study conducted virological investigations of calves showing diarrhea and respiratory and neurological signs.
Methods:
An outbreak of diarrhea, respiratory, and neurological disorders occurred among the 12 calves in July 2022 in Istanbul, Türkiye. Two of these calves exhibited neurological signs and died a few days after the appearance of symptoms. One of these calves was necropsied and analyzed using molecular and histopathological tests.
Results:
BCoV RNA was detected in the brain, lung, spleen, liver, and intestine of the calf that had neurological signs by real-time reverse transcription polymerase chain reaction.Immunostaining was also observed in the intestine and brain. A 622 bp S1 gene product was noted on gel electrophoresis only in the brain. Phylogenetic analysis indicated that the BCoV detected in this study had a high proximity to the BCoV strain GIb with 99.19% nucleotide sequence homology to the strains detected in Poland, Israel, Türkiye, and France. No distinct genetic lineages were observed when the brain isolate was compared with the respiratory and enteric strains reported to GenBank. In addition, the highest identity (98,72%) was obtained with the HECV 4408 and L07748 strains of human coronaviruses.
Conclusions
and Relevance: The strain detected in a calf brain belongs to the GIb-European lineage and shares high sequence homology with BCoV strains detected in Europe and Israel. In addition, the similarity between the human coronaviruses (4408 and L07748) raises questions about the zoonotic potential of the strains detected in this study.

PURPOSE: The aim of the present study was to evaluate the predictive value of volume of the specimen/body mass index (VS/BMI) ratio for recurrence after surgical therapy of pilonidal disease. METHODS: Ninety-eight patients with primary pilonidal disease were enrolled in this study. The VS/BMI ratio was calculated for each patient. This ratio was defined as the specimen index (SI). VS, BMI and SI were evaluated to determine whether there is a relationship between these parameters and recurrence of pilonidal disease. In addition, the predictive ability of SI for recurrence was analyzed by receiver operating characteristic (ROC) curve. RESULTS: VS and SI were found to be higher in patients with recurrence. ROC curve analysis showed that VS and SI are predictive factors for recurrence in patients treated with primary closure, nevertheless our new index had higher sensitivity and specificity than VS (sensitivity 85.7% vs 71.4% and specificity 90.7% vs 85.1%, respectively). The cut-off level for the greatest sensitivity and specificity for SI was 1.29. CONCLUSION: Recurrence is higher in patients with high VS regardless of the operation method. SI may be a predictive value in patients treated with primary closure.

Journal of Stroke 2015;17(3):312-319
BACKGROUND AND PURPOSE: To investigate an association between left atrial (LA) structural and P wave dispersion (PWD) during sinus rhythm, and electrical remodeling in cryptogenic stroke (CS) patients. METHODS: Forty CS patients and 40 age- and sex-matched healthy controls were enrolled. P wave calculations were based on 12-lead electrocardiography (ECG) at a 50-mm/s-paper speed with an amplitude of 10 mm/mV. Difference between the maximum and minimum P wave duration was the P wave dispersion (PWD=Pmax-Pmin). LA deformation was evaluated by speckle tracking echocardiography within 3 days of the acute event. RESULTS: PWD was 30.1+/-7.0 ms and 27.4+/-3.5 ms in CS and control group (P=0.02), whereas LA maximum volume index [LAVImax] was 20.4+/-4.5 mL/m2 and 19.9+/-2.4 mL/m2 in CS and control group, respectively (P = 0.04). While global peak LA strain was [pLA-S] (LA reservoir function) 41.4 +/- 6.3% and 44.5 +/- 7.1% in CS and control group, (P = 0.04), global peak late diastolic strain rate values [pLA-SRa] (LA pump function) were 2.5 +/- 0.4% and 2.9 +/- 0.5% in CS and control group, respectively (P = 0.001). A mild and a strong negative correlation between global pLA-S and LAVImax (r=-0.49; P<0.01), and between PWD and global pLA-S (r = -0.52; P < 0.01), respectively, was observed in CS. CONCLUSIONS: Increased PWD is associated with impaired LA mechanical functions and enlargement, and involved in the pathophysiology of AF or an AF-like physiology in CS.
