In most cases there is a single etiological factor causing neuromotor developmental delay and epilepsy while sometimes more than one gene may be involved. These include the autosomal recessive inherited CAMSAP1 gene, which is associated with cortical developmental malformations such as pachygyria and lissencephaly and the autosomal dominant inherited NBEA gene, which plays crucial roles in vesicle trafficking as well as synapse structure and function. Loss of function of both genes together is a well-known disease mechanism.

Foreign bodies in the breast are rarely encountered and may infrequently lead to complications such as persistent breast pain, abscess, and/or granuloma formation, pneumothorax, or cardiac tamponade. We aimed to present a case with a foreign body in her right breast, which was diagnostically missed in previous screenings. A 44-year-old asymptomatic woman, who was included in the national breast cancer screening program, was found to have a 2 cm-sized metallic foreign body in the upper-outer quadrant of her right breast via mammographic imaging.

The negative effects of global warming also directly affect aquatic populations. Consequences such as evaporation due to chronic temperature increase, increase in salinity, and increase in stock density per unit volume are potential stress factors. While creating the trial design, an attempt was made to simulate the effects of global warming, especially on species living in salty and brackish water biotopes.

Aim: To investigate the effects of anti-human Leucocyte Antigen (HLA) antibody positivity on early hematopoietic stem cell transplantation (HSCT) results in patients with thalassemia major (TM).

Methods: One hundred and twenty-four HLA-matched HSCTs were performed in patients with TM between 2015 and 2022. Ninety-one patients were screened for anti-HLA antibodies by testing panel reactive antigens (PRA).

: Preeclampsia, a pregnancy-induced hypertensive disorder, shares cardiovascular characteristics in etiology, prognosis, and fetomaternal risks. Electrocardiography plays a pivotal role in assessing cardiovascular risks. Beyond conventional predictors, identifying easily obtainable and reproducible electrocardiographic markers may significantly contribute to the early identification of individuals at risk of preeclampsia.

Background And Hypothesis: Schizophrenia is a complex disorder thought to have neurodevelopmental and neurodegenerative aspects. Optical coherence tomography (OCT) measurements of schizophrenia patients revealed that the retinal layers of these patients were thinner than those of healthy controls. This study aimed to examine retinal changes in first-episode psychosis patients treated with electroconvulsive therapy (ECT) via OCT.

  • Contagious caprine pleuropneumonia (CCPP) is a serious and rapidly spreading disease in goats, causing significant economic losses in Asia, Africa, and the Middle East.* -
  • The study examined lung tissues from 40 goats with CCPP and 6 healthy controls to analyze the role of mast cells and the proteins IL-17 and IL-1β during different inflammation stages (peracute-acute vs. subacute-chronic).* -
  • Findings showed increased mast cell numbers and levels of IL-17 and IL-1β during the peracute-acute phase compared to controls, while these levels decreased in the subacute-chronic phase, highlighting their importance in the disease's progression.*

The Varroa destructor represents a significant threat to honey bees, leading to substantial yield losses and declines in colony health. Defense behaviors, including grooming (auto and allogrooming), serve as crucial mechanisms against Varroa infestations, yet the genetic basis of these behaviors remains elusive. This study examines the expression levels of hymenoptaecin (hym), neurexin-1 (AmNrx1), and CYP9Q3, potentially associated with defense behavior, in colonies of the Muğla honey bee ecotype (Apis mellifera anatoliaca) subjected to a Varroa selection program.

Article Synopsis
  • - The study focuses on validating and testing the reliability of the Turkish version of the Lumbar Stiffness Disability Index (Tr-LSDI) for patients post-lumbar fusion surgery, as the original version has not been confirmed in Türkiye.
  • - A total of 66 patients participated, with various analyses confirming that the Tr-LSDI has high content validity, good internal consistency (Cronbach's alpha of 0.934), and excellent test-retest reliability (ICC of 0.980).
  • - Results showed a strong correlation between Tr-LSDI scores and both the number of fusion levels and the Oswestry Disability Index, affirming its effectiveness as a tool for assessing lumbar stiffness in clinical settings. *

This study aims to explore the concept of liminality in the lives of chronic kidney disease (CKD) patients in Turkiye who are undergoing dialysis while awaiting kidney transplants. The research focuses on how patients experience this transitional state, being between life stages, and how they cope with the uncertainty of their condition while aspiring for a transplant. The research involved in-depth, semi-structured interviews and participant observations of 34 dialysis patients who had been registered on the national organ waiting list for over five years.

Article Synopsis
  • The study investigates the progression of Behçet's disease when it starts in childhood and how it affects patients in adulthood.
  • Out of 112 pediatric patients, 93 were analyzed, revealing that around 52.5% had major organ involvement, primarily affecting the eyes, with some showing new complications as they transitioned into adulthood.
  • The findings highlight the importance of continued monitoring for these patients, as nearly one-third experienced new symptoms or relapses post-childhood, underscoring the need for regular follow-ups to mitigate potential long-term damage.

  • Lateral condyle fractures are common in children (ages 6-10) and can be treated using open or closed reduction methods, but guidelines on treatment choices are unclear.
  • This study reviewed 111 patients who had surgery for Song type 4 and 5 fractures from 2011-2016, comparing outcomes between those treated with closed reduction and percutaneous pinning (CRPP) and open reduction and internal fixation (ORIF).
  • Results showed no significant differences in patient demographics or fracture displacement, but radiological outcomes indicated a higher rate of lateral spur formation in the ORIF group (47.5%) compared to the CRPP group (23%).

Radical cystectomy (RC) with the formation of an ileal orthotopic neobladder (ONB) may adversely affect long-term health-related quality of life (HRQOL). An advanced age at the time of ONB construction could further exacerbate the decline in HRQOL. This study aims to establish an evidence-based age threshold at the time of RC with ONB, beyond which a significant deterioration in HRQOL is observed.

Purpose: To determine whether color-rendered 3D MR neurography (MRN) images (heatmaps) improve diagnostic accuracy, reader confidence levels, and time savings to assess LS plexus lesions compared to the conventional grayscale images.

Materials And Methods: A cross-sectional study included adults of all genders with randomly chosen MRNs of LS plexus and known reference standards of normal or neuropathy (plexopathy and radiculopathy). Heatmaps were constructed using 3D MRN STIR images and color rendered with higher intensity to yellow and lower intensity to darker-red colors in 1-2 min on average and were available on PACS for the readers.

Background: Unexpected, sudden, and tragic losses can prompt us to reflect on the concept of a "good death." The earthquake disaster that struck our country in 2023 vividly demonstrated the challenging impact of such events, which can turn lives upside down and compel us to question the notion of a "good death." This study aims to determine the perceptions of a "good death" and the levels of trauma experienced by physicians and nurses who directly witnessed the earthquake disaster, and to understand the relationship between these factors.

Article Synopsis
  • The study investigates the link between Behçet's disease (BD) and apical periodontitis (AP), noting that this correlation hasn't been explored before.
  • It involved 98 participants (49 with BD and 49 controls), where AP presence was assessed through clinical and radiographic methods, considering different factors like medication and disease severity.
  • Results showed a higher prevalence of AP in BD patients compared to controls, indicating a significant association, but the effectiveness of endodontic treatments for BD patients was similar to that of healthy individuals.
