Kinematics of the East Anatolian Fault Zone between Turkoglu (Kahramanmaras) and Celikhan (Adiyaman), eastern Turkey

In this study we determined the stress regime acting along the East Anatolian Fault Zone between Turkoglu (Kahramanmaras) and Celikhan (Adiyaman), from the Neocene to present-day, based on the inversion of striations measured on faults and on the focal mechanisms of earthquakes having magnitudes greater than 5.0. The inversions yield a strike-slip stress regime with a reverse component (i.e., transpression) operative in the Neocene to present with a consistent N-to NW-trending or, axis 156 +/- 11 degrees and an E- to NE-trending sigma(3) axis, sigma(7) 9 degrees sigma(3), producing left-lateral motion along the East Anatolian Fault Zone. The inversions of focal mechanisms yield a strike-slip stress deviator characterized by an approximately N-S (N1 degrees W)-trending sigma(1), and an approximately E-W (N89 degrees E)-trending sigma(3) axis. Both the kinematic analysis and structural observations indicate that the stress regime operating in the study area has had a transpressional character, giving rise to the Mio-Pliocene compressive structures (reverse faults, thrusts and folds) observed in the study area. Field observations allow estimation of a Pliocene age for the strike-slip East Anatolian Fault Zone

Infected pancreatic necrosis: outcomes and clinical predictors of mortality. A post hoc analysis of the MANCTRA-1 international study

: The identification of high-risk patients in the early stages of infected pancreatic necrosis (IPN) is critical, because it could help the clinicians to adopt more effective management strategies. We conducted a post hoc analysis of the MANCTRA-1 international study to assess the association between clinical risk factors and mortality among adult patients with IPN. Univariable and multivariable logistic regression models were used to identify prognostic factors of mortality. We identified 247 consecutive patients with IPN hospitalised between January 2019 and December 2020. History of uncontrolled arterial hypertension (p = 0.032; 95% CI 1.135-15.882; aOR 4.245), qSOFA (p = 0.005; 95% CI 1.359-5.879; aOR 2.828), renal failure (p = 0.022; 95% CI 1.138-5.442; aOR 2.489), and haemodynamic failure (p = 0.018; 95% CI 1.184-5.978; aOR 2.661), were identified as independent predictors of mortality in IPN patients. Cholangitis (p = 0.003; 95% CI 1.598-9.930; aOR 3.983), abdominal compartment syndrome (p = 0.032; 95% CI 1.090-6.967; aOR 2.735), and gastrointestinal/intra-abdominal bleeding (p = 0.009; 95% CI 1.286-5.712; aOR 2.710) were independently associated with the risk of mortality. Upfront open surgical necrosectomy was strongly associated with the risk of mortality (p < 0.001; 95% CI 1.912-7.442; aOR 3.772), whereas endoscopic drainage of pancreatic necrosis (p = 0.018; 95% CI 0.138-0.834; aOR 0.339) and enteral nutrition (p = 0.003; 95% CI 0.143-0.716; aOR 0.320) were found as protective factors. Organ failure, acute cholangitis, and upfront open surgical necrosectomy were the most significant predictors of mortality. Our study confirmed that, even in a subgroup of particularly ill patients such as those with IPN, upfront open surgery should be avoided as much as possible.

Global disparities in surgeons’ workloads, academic engagement and rest periods: the on-calL shIft fOr geNEral SurgeonS (LIONESS) study

: The workload of general surgeons is multifaceted, encompassing not only surgical procedures but also a myriad of other responsibilities. From April to May 2023, we conducted a CHERRIES-compliant internet-based survey analyzing clinical practice, academic engagement, and post-on-call rest. The questionnaire featured six sections with 35 questions. Statistical analysis used Chi-square tests, ANOVA, and logistic regression (SPSS® v. 28). The survey received a total of 1.046 responses (65.4%). Over 78.0% of responders came from Europe, 65.1% came from a general surgery unit; 92.8% of European and 87.5% of North American respondents were involved in research, compared to 71.7% in Africa. Europe led in publishing research studies (6.6 ± 8.6 yearly). Teaching involvement was high in North America (100%) and Africa (91.7%). Surgeons reported an average of 6.7 ± 4.9 on-call shifts per month, with European and North American surgeons experiencing 6.5 ± 4.9 and 7.8 ± 4.1 on-calls monthly, respectively. African surgeons had the highest on-call frequency (8.7 ± 6.1). Post-on-call, only 35.1% of respondents received a day off. Europeans were most likely (40%) to have a day off, while African surgeons were least likely (6.7%). On the adjusted multivariable analysis HDI (Human Development Index) (aOR 1.993) hospital capacity > 400 beds (aOR 2.423), working in a specialty surgery unit (aOR 2.087), and making the on-call in-house (aOR 5.446), significantly predicted the likelihood of having a day off after an on-call shift. Our study revealed critical insights into the disparities in workload, access to research, and professional opportunities for surgeons across different continents, underscored by the HDI

Granulomatous conjunctivitis in an ostrich

Ostriches lack meibom glands, but have small lacrimal glands ventral to the lateral canthus, with ductules that open into the inside of the lower eyelid. Chalazion is a chronic granulomatous inflammation of the meibom glands that may develop from blockage of the ductules into the conjunctiva. A 2-year-old female ostrich presented with chronic granulomatous conjunctivitis, with clinical and histopathologic findings similar to chalazion of other species. The granulomatous dacryoadenitic mass was excised and no recurrence occurred at 4 months. This is the first case of chronic granulomatous conjunctivitis reported in the ostrich

Urethrostomy done using the anastomosis technique of the prepuce mucosa to the pelvic urethra in cats with penile urethral obstruction

Penile urethral obstruction in cats is a commonly seen clinical manifestation. In cases where there is no response to catheterisation and medical intervention, surgery is needed to provide urination and correct uremia and hyperkalemia. Several surgical techniques have been described. The perineal urethrostomy technique, reported by Wilson and Harrison in 1971, has been used extensively and since then various modifications of this technique have been developed by other researchers. In 2000, Yeh and Chin described a modified perineal urethrostomy technique created by use of the prepuce mucosa. This technique was used in our clinic in 20 cats with penile urethral obstruction. Seventeen cats recovered without complication. A 2.6 mm diameter catheter was placed in each of the 3 cases in which leakage was determined in the anastomosis site. The urine gathered in the site subcutaneously was drained. Normal urination was achieved in 2 of the 3 patients treated with this technique. The remaining case was re-operated and the perineal urethrostomy technique, in which the urethra was sutured to the perineal skin (the Wilson and Harrison method, 1971), was applied. The advantages of this technique over the classical perineal urethrostomy technique are; return to urination shortly after the operation, better urination potential compared to normal cats, a more aesthetic appearance compared to other techniques (similar to a castrated cat), no narrowing of the orifice caused by re-growth of hair. It was also understood that, anastomosis of the urethra and the prepuce mucosa must be carried out with utmost care in order to prevent urine leakage

Fundoscopic normal variations of the retina in Turkish sheepdogs and multifocal retinal dysplasia: A comparative study in Akbash and Kangal breeds

In this study, normal fundoscopic variations and genetic retinal diseases of Turkish sheepdogs (Akbash and Kangal) have been assessed. According to comparative results obtained from 35 Akbash and 35 Kangal dogs, it was determined that blue tapetal regions were present at a rate of 65% in the Akbash breed and yellow-green tapetal regions were present at a rate of 60% in the Kangal breed. No fundoscopic or clinical sign suggesting albunism, subalbunism or progressive retinal atrophy was observed in either group. However, multifocal retina dysplasia was seen at a rate of 17.1% in the Akbash breed and 5.4% in the Kangal breed. The fact that all of these lesions, which presented typical fundoscopic appearance, were seen in females was interpreted as coincidental. It was of particular interest that these retinal dysplasias, which did not disrupt sight, occurred 3 times more in the Akbash breed compared to the Kangal breed

Limbal pseudotumor in a Cob Pony

A tumor-like tissue mass of lateral-limbal site in the right eye of a 12-year-old Cob Pony mare was presented for surgical removal. The mass, covering the lateral limbus, bulbar conjunctiva and part of the cornea, was surgically removed, and the corneal defect repaired with a pedicle bulbar conjunctival graft. The mass was inflammatory in nature containing mononuclear cells. No recurrence or complication occurred at 6- and 12-month follow-up examination

-ABSTRACTS POSTERS- ABSTRACTS PREPUCIAL URETHROSTOMY PERFORMED USING THE COATING TECHNIQUE

Penile urethral obstruction in cats is a commonly seen clinical presentation. In cases where there is no response to catheterisation or medical intervention, surgery is needed to enable urination and correct uremia and hyperkalemia. Several surgical techniques have been described. Great care must be taken to minimize leakage in the anastomosis site and promote healing when performing the pelvic urethra and prepucial mucosa anastomosis. To achieve this, the line of anastomosis has been reinforced by covering the anastomosis with the bilateral bulbourethral tissue, m. ischiourethralis and m. ischiocavernosus using simple mattress sutures. This modifi cation, which varies from the technique performed by Yeh and Saroglu, has been termed the coating technique. Advantages of this RS S new technique over standard perineal urethrostomy have been discussed. This technique was used in the treatment of 49 cats with penile urethra obstruction presented to our clinic. 47 cats showed uncomplicated recovery. Stenosis developed after 1 month in 2 cases in which normal urination was resumed by performing the standard perineal urethrostomy technique. Following anastomosis, a male dog urethral catheter with an outer diameter of 2.6 mm was placed in each patient. The reasons for using a catheter in this technique were explained. In order to avoid infection, the catheter was changed at 7-day intervals, remaining in situ for 2 weeks and was removed after 14 days. All cats with obstruction returned to good health
