Labiaplasty revision surgery with using clitoral hood flap: A case-cohort study
(Springer, 2024) Şahin, Eda Adeviye; Ağlamış, Özgür; Şahin, Hanifi; Ozan Şahin, Elif; Yılmaz Ergani, Seval
Background: The demand for labia minora reduction surgery has increased due to aesthetic preferences and discomfort caused by labial hypertrophy. This study aims to share experiences with labial reconstruction using clitoral hood flaps in patients who underwent aggressive trim labiaplasty. Methods: Twenty-eight patients who had previously undergone only labiaplasty surgery were included in this study. Surgical techniques focused on preserving blood supply and achieving symmetry. Postoperative care included hospitalization, wound care training, and regular follow-up visits. Complications were monitored and managed as needed. Results: All 28 patients, comprising 23 bilateral and 5 unilateral labiaplasty cases, underwent revision surgery using 49 clitoral hood flaps. Complications occurred in 6 cases, including suture dehiscence, flap necrosis, and infection, all of which were effectively managed. All flaps maintained their viability, and high patient satisfaction was reported. Conclusion: Clitoral hood flap reconstruction following aggressive trim labiaplasty is a viable technique with minimal complications and high patient satisfaction. Further multicenter, long-term studies are necessary to validate these findings and improve surgical outcomes.

Distribution of branches of anterior choroidal artery in the uncus: An anatomical study
(Springer, 2024) Kaçur, İdil; Nteli Chatzioglou, Gkionoul; Nas, Emine; Şahan, Orhun; Kale, Ayşin; Çakır, Halit; Coşkun, Osman; Gayretli, Özcan
The aim of our study was to examine the relationship between uncus and uncal branches of anterior choroidal artery (AChA) and to observe the morphological and morphometric features of these branches. 124 hemispheres from 62 fresh cadavers were included in the study. Measurement of the length of AChA and the distances of the uncal branches to the origin of AChA were measured by ImageJ software. Morphological variations of uncal branches originating from AChA were observed. The length of AChA was found as mean 26.24 ± 4.34 mm. It was determined that the average distance of these uncal branches arising from the AChA was 13.48 ± 7.31 mm. In 4 out of 124 AChAs, no branches were observed. 594 branches originating from 120 were detected. 130/594 branches appeared to be terminal branches. AChAs of 80/120 hemispheres have been reported to have uncal branches. Thirty of 130 uncal branches were observed to originate as the first branch of AChA. It was found that uncal branches may originate from AChA with a variability between 1 and 4. When evaluated according to the origin of each branch from the AChA, it was observed that the uncal branches originated from the midpoint of the AChA on average. Also, in 64 hemispheres, morophological variations were detected regarding the origin of uncal branches. We believe that the morphological and morphometric data we obtained from the uncal branches of the AChA are of clinical importance in terms of understanding this complex region and minimizing errors in surgical procedures.

Early period survival and neurologic prognosis in newborns with perinatal asphyxia: A tertiary center experience and a mortality chart
(Brieflands, 2025) Yaman, Akan; Kandemir, İbrahim; Alp Ünkar, Zeynep
Background: Clinicians require more data regarding mortality and brain damage risk factors in perinatal asphyxia. Objectives: To assess early term outcomes and identify mortality risk factors in perinatal asphyxia. Methods: This study was conducted in a referral-center tertiary intensive care unit in Istanbul, Turkey, between 2016 and 2023. We included all patients who underwent therapeutic hypothermia treatment due to perinatal asphyxia. We recorded laboratory follow-up data, magnetic resonance imaging (MRI) findings, amplitude-integrated electroencephalograms (aEEG) results, mortality, and clinical outcomes. Both conventional frequentist statistical methods and Bayesian methods were used for analysis. Results: A total of 164 patients were included in the study, with an overall mortality rate of 9.8%. Risk factors for mortality included LDH, troponin I, INR, lactate, 2nd day creatinine, voltage anomalies, seizures, and male gender, as well as APGAR scores. A basic chart for mortality prediction was developed. The Sarnat score showed strong evidence, and APGAR 1 showed anecdotal evidence for association with brain damage, although brain damage was independent of laboratory results and other clinical findings, based on moderate and anecdotal evidence from Bayesian calculations. Cranial MRI findings revealed profound damage in 14.8% of Sarnat 1, 21.8% of Sarnat 2, and 50% of Sarnat 3 patients. Conclusions: This study presents prognostic factors for survival and brain damage in perinatal asphyxia. We recommend obtaining cranial MRI for all patients diagnosed with asphyxia, as most laboratory tests were independent of brain damage. Given that profound brain damage can occur even in Sarnat stage I patients, we emphasize the importance of therapeutic hypothermia for these patients.

Yaşlılarda safra kesesi hastalıklarına yaklaşım
(Akademisyen Kitabevi, 2024) As, Abdullah; Kanat, Burhan Hakan; Öndeş, Bahadır
Yaşlılığın ne olduğu ve hangi yaştan itibaren başladığı daima tartışılan bir konu olmuştur. Son yüzyıl içinde, tıp ve teknolojideki gelişmekte paralel olarak insan yaşamının uzadığı bilinen bir gerçektir. Bu durumla birlikte, dünya üzerindeki insan nüfusunun giderek yaslandığı ve yaşlı hastalara cerrahi müdahale gerekliliğinin giderek artmakta olduğu gözlenmektedir. Dünya Sağlık Örgütü verilerine göre 2019 yılı itibari ile 60 yaşını geçen insan popülasyonu 1 milyara yükselmiştir. 2030 yılına kadar bu rakamın 1.4 milyara, 2050 yılı itibariyle ise 2.1 milyara çıkacağı ön görülmektedir.

The worldwide medical impact of hepatitis D virus infection: Focus to Central Asia
(Academic Press, 2025) Aghayeva, Gulnara; Rizzetto, Mario; Örmeci, Necati; Turcanu, Adela; Abbas, Zaigham; Bedewy, Essam; Satapathy, Sanjaya K.; Al-Mahtab, Mamun; Singh, Shivaram Prasad; Akbar, Sheikh Mohammad Fazle; Ala, Aftab; Schiano, Thomas D.
Hepatitis D virus (HDV) requires hepatitis B virus (HBV) for its replication. Concurrent infection with HBV and HDV results in more severe disease outcomes than infection with HBV alone, inducing cirrhosis, fulminant hepatitis, and hepatocellular carcinoma, and representing a significant cause of global mortality. Central Asia remains an area of high HDV prevalence but local features of the infection were poorly detailed in the past. Until recently, interferon has represented the only treatment option in patients with chronic hepatitis D; however, it is associated with low efficacy and a high burden of side effects. The discovery of the entry inhibitor bulevirtide has represented a breakthrough in HDV treatment. Other compounds (i.e., lonafarnib, new anti-hepatitis B virus drugs) are under development to provide alternative or combined strategies for HDV cure.
