Objectives: The aim of the present study is to develop a Turkish version of the ABILHAND-Kids Survey, which evaluates upper extremity function in children with cerebral palsy (CP), and to carry out a validity and reliability study of the survey for Turkish CP patients. Materials and methods: Between November 2016 and March 2017, a total of 109 pediatric CP patients (62 males, 47 females; mean age 9.3±2.9 years; range, 6 to 15 years) followed in our outpatient clinic were included. The demographic characteristics and type of CP of the patients were recorded. A functional evaluation was made using the ABILHAND-Kids and Manual Ability Classification System (MACS) surveys. The reliability of the surveys was tested based on internal consistency (Cronbach`s α) and test-retest (intraclass correlation coefficient [ICC]) methods. The validity of the approach was evaluated using converted scores from an ABILHAND-Kids Rasch analysis and a correlation of the MACS levels. Results: The ICC value for the test/retest reliability was 0.98 and internal consistency was 0.94. A strong negative correlation was found between the Turkish version of the ABILHAND-Kids and MACS surveys (r=-0.849; p<0.001). A Rasch analysis indicated good item fit, unidimensionality, and model fit. Conclusion: The Turkish version of the ABILHAND-Kids survey is a reliable and valid scale for the assessment of manual ability in Turkish children with CP.

Purpose: This study aimed to evaluate the effectiveness of the laser-assisted new attachment procedure (LANAP) and low-level laser therapy (LLLT) on clinical, biochemical, and radiographic parameters when applied alongside scaling and root planing (SRP). Methods: The study was designed as a randomized controlled, single-blind, parallel trial involving 68 patients diagnosed with periodontitis. The participants were divided into three groups: Group 1: SRP (control), Group 2: LANAP, and Group 3: LLLT. Clinical measurements, gingival crevicular fluid (GCF) samples, and standard periapical radiographs were obtained pre-treatment and at one- and three-month follow-ups. In GCF, interleukin-1beta (IL-1β), interleukin-10 (IL-10), and vascular endothelial growth factor (VEGF) were analyzed. Results: In moderate (4–6 mm) and deep pockets (≥ 7 mm), laser-treated groups showed a significant reduction in pocket depth (PD) and clinical attachment level (CAL) compared to the control group. However, there were no statistically significant differences in biochemical markers between the groups. Group 2 demonstrated significant bone filling compared to the control group. Conclusion: In deep pockets, laser-treated groups provide additional benefits to SRP. The application of LLLT positively affected recession (REC).

Aim: To investigate the changes in ophthalmologists' working conditions and mental health status in Turkey during the first wave of the COVID-19 outbreak and reveal the relevant individual and workplace-related factors. Methods: This cross-sectional, nationwide, the survey-based study collected data between June and September 2020. Demographic characteristics, working conditions, precautionary measures in the workplace, and participants' Depression Anxiety Stress Scale (DASS-21) and Insomnia Severity Index (ISI) ratings were investigated. Results: This study included 360 actively working ophthalmologists. While 64% of them worked in the pandemic hospitals, 44% were actively involved in COVID-related departments. Among those, 56 (35%) declared that they had all personal protective equipment in sufficient quantity in their COVID department. Despite the restrictions, 32% reported continuing to see 25 to 50 patients per day in ophthalmology clinics, with the most common complaint being the ocular "itching and burning" sensation. 53% stated that they did not perform any surgeries. Symptoms of depression, anxiety, stress and insomnia were present in 65%, 56.9%, and 43% and 46.9% of participants, respectively. All DASS-21 subscales and ISI scores were found to be significantly higher during the pandemic. Female gender, older age, and lower satisfaction levels of hygiene conditions in COVID clinics were independent predictors of higher DASS-21 subscale scores in multivariate analysis. Being a resident was a major predictor of depression. Ophthalmologists working in a pandemic hospital were more likely to experience insomnia. Conclusion: Ophthalmologists have actively worked in COVID departments during the pandemic. Increased psychological distress among ophthalmologists compared to the pre-pandemic period is caused by personal factors and many determinants related to the workplace and practice patterns. Therefore, decreasing the transmission risk by creating a protective workplace and developing psychological support policies should be considered to minimize adverse psychological effects.

The precise assessment of hemothorax risk resulting from a rib fracture is not feasible. CT images, patient characteristics, and clinical experience are utilized in daily practice to assess risk intuitively. This study aimed to identify specific markers on CT images that can predict the risk of hemothorax. The study was retrospectively conducted between May 2021 and December 2023 at three different centers. Patients diagnosed with hemothorax at the initial assessment or during follow-up were identified among those being followed for rib fractures. An investigation was carried out to examine the relationship between the number of rib fractures, displacement status, and the location of the fracture on the rib arch with the risk of hemothorax. Of the 273 patients included in the study, 201 (73.6%) were male. The mean age was 53.9 ± 17.27 (19–93) years. Lateral (p = 0.029) and posterior (p < 0.001) location of the fracture and displacement of at least one fracture (p = 0.003) were associated with an increased risk. There was a significant correlation between the number of rib fractures and the risk of hemothorax (p < 0.001). The optimal cut-off for the number of rib fractures associated with a high risk of hemothorax was determined to be 4. Anatomical characteristics of a rib fracture can be useful to assess the risk of hemothorax practically in patients with thoracic trauma especially in emergency rooms. Patients with four or more rib fractures, at least one displaced rib fracture, and lateral and posterior rib fractures should be followed more carefully for hemothorax.

Aims: Left ventricular non-compaction cardiomyopathy (LVNC) is a poorly understood entity resulting in heart failure. Whether it is a distinct form of cardiomyopathy or an anatomical phenotype is a subject of discussion. The current diagnosis is based on morphologic findings by comparing the compacted to non-compacted myocardium. The study aimed to compare demographic and prognostic variables of patients with dilated cardiomyopathy (DCM) and LVNC. Emphasis was given to cardiac magnetic resonance (CMR) imaging analysis. Data on survival were also assessed. Methods and results: We retrospectively evaluated the characteristics and outcomes of 262 non-ischaemic cardiomyopathy patients with LVNC and DCM phenotypes. Petersen's CMR criteria of non-compacted to the compacted myocardial ratio 2.3 were used to diagnose LVNC. The primary endpoint was a composite endpoint of major adverse cardiovascular events comprising cardiovascular-related death, left ventricular assisted device implantation, or heart transplantation. A total of 262 patients with CMR data were included in the study. One hundred fifty-five patients who fulfilled CMR criteria were diagnosed as LVNC. CMR findings revealed that LVNC patients had higher left ventricular end-diastolic (137.2 ± 51.6, 116.8 ± 44.6, P = 0.002) and systolic volume index (98.4 ± 49.5, 85.9 ± 42.7, P = 0.049). Cardiac haemodynamics, cardiac output (5.61 ± 2.03, 4.96 ± 1.83; P = 0.010), stroke volume (73.9 ± 28.8, 65.1 ± 25.1; P = 0.013), and cardiac index (2.85 ± 1.0, 2.37 ± 0.72; P < 0.0001), were higher in LVNC patients. Of all the 249 patients, 102 (40.9%) patients demonstrated late gadolinium enhancement (LGE). According to Petersen's criteria, the Kaplan–Meier survival outcome did not reveal significant differences (hazard ratio [HR]: 1.53, 95% confidence interval [CI]: [0.89–2.63], P = 0.11). The presence or pattern of LGE did not show significant importance for endpoint-free survival. Most of the sub-epicardial LGE pattern was found in LVNC patients (94.4%). When receiver operator characteristics analysis was applied to NC/C ratio to discriminate the primary endpoint, a higher NC/C ratio of 2.57 was associated with adverse events (HR: 1.90, 95% CI: [1.12–3.24], P = 0.016). Conclusions: Our study questions the criteria being used for the diagnosis of LVNC. Further evaluation of CMR variables and association of these findings with demographic variables and survival is mandatory.
