(2020) Isik, Semra; Cevik, Serdar; Turhan, Ali Haydar; Baygul, Arzu; Hanimoglu, Hakan; 32239487
AIM: To investigate the relationship between the distribution of ABO or Rhesus (Rh) blood group antigens and the incidence of myelomeningocele. MATERIAL and METHODS: A retrospective data was reviewed for all myelomeningocele patients operated at a tertiary academic hospital between years 2014 and 2019. Age, sex, delivery method, physical and neurological examination findings, and radiological findings alongside with blood type of each patient were recorded. The data of blood group distribution among the study patients was compared to the data of healthy individuals in the same region. RESULTS: Patients with group B and AB showed a higher chance of developing myelomeningocele. Rh-positive blood group was associated with high incidence of myelomeningocele (93.5%), whereas Rh-negative blood group showed least association (6.5%). Rh-positive blood group was also found to be more frequent in patients with myelomeningocele with hydrocephalus and Chiari malformation. CONCLUSION: The findings of this study show that ABO and Rh blood groups have an effect on the development of myelomeningocele under the influence of environmental or genetic factors.

(2020) Cevik, Serdar; Yilmaz, Hakan; Kaplan, Atilla; Yetkinel, Selcuk; Evran, Sevket; Calis, Fatih; Akkaya, Enes; Katar, Salim; Baygul, Arzu; Hanimoglu, Hakan; 0000-0002-2165-9168; 31851846; AAL-1530-2021
Introduction: Estrogen helps to maintain the health of collagen-containing tissues including the intervertebral disc. Estrogen deficiency after menopause negatively affects the quality of vertebral end plates and induces development of degenerative disc disease (DDD). However, there is no study examining the relationship between parity and spinal degeneration in young women. The aim of this study was to define the relationship between parity and development of vertebral endplate signal changes and DDD in young premenopausal women. Materials and methods: This case-control case study included 224 patients aged 20-40 years with a history of low back pain for at least 3 months. Pfirrmann's grade, Modic changes (MCs), and Schmorl's nodes (SNs) were graded based on magnetic resonance images. Patients' parity, demographics, body mass index, physical activity level, and disability scores were assessed using a questionnaire. Results: The prevalence of abnormal total Pfirrmann's score (>10) and MCs was higher in primiparous patients than multiparous and grand-multiparous; however, it was not statistically significant. The presence of SN was statistically significantly associated with low parity. According to multivariate logistic regression analysis, it was found that the number of births increases by 1 unit, the abnormality in Pfirrmann's score decreases by 1.36 times. Conclusions: This cross-sectional study shows that parity is associated with DDD and vertebral end plate changes. SNs were significantly associated with parity. Modic changes and DDD were less common in grand multipara and multipara young women than in primipara women. These results indicate that low parity may possibly be associated with the development of spinal degeneration.
Effect of Antithrombotic Therapy on Development of Acute Subdural Hematoma After Burr Hole Drainage of Chronic Subdural Hematoma
(2020) Yuksel, Mehmet Onur; Cevik, Serdar; Erdogan, Baris; Tunckale, Tamer; Katar, Salim; Isik, Semra; Caliskan, Tezcan; Evran, Sevket; 32996579
AIM: To evaluate the relationship between the time from cessation of anticoagulant/antiplatelet medication to surgery and risk of postoperative acute subdural hematoma (ASDH) after burr hole drainage of chronic subdural hematoma (CSDH). MATERIAL and METHODS: A retrospective study of patients who underwent burr hole drainage of CSDH between December 2014 and December 2019 was performed. Demographic and clinical data regarding age, gender, medication (antithrombotic therapy), smoking, daily alcohol consumption, history of head trauma, presenting symptoms, and neurological examination were collected from the medical records. Patients were divided into 3 groups based on time from referral to surgery: <24 hours, 24-72 hours, and >72 hours. RESULTS: One hundred seventeen patients underwent burr hole drainage of CSDH during the 5-year study period. Seventy-two patients were male (61.5%) and 45 were female (38.5%). Mean age was 70.5 +/- 7.2 years. Postoperative ASDH occurred in 2 of the 32 patients (6.3%) who were not taking antithrombotic medication and 6 of the 85 patients (7.1%) who were taking antithrombotic medication. The difference was not significant (p=0.797). CONCLUSION: The risk of ASDH after burr hole drainage of CSDH was not affected by antithrombotic medication. Although the literature suggests that antiplatelet and anticoagulant drugs to be discontinued between 5 and 7 days before surgery, our results showed that acute hemorrhage was not detected in any patient who underwent surgery more than 72 hours after referral.
The Role of Age on Effectiveness of Active Repositioning Therapy in Positional Skull Deformities
(2020) Ozkilic, Alper; Cevik, Serdar; Isik, Semra
Purpose: Non-synostotic positional deformities are currently diagnosed in nearly half of the newborns, however not any evidence-based guidelines are available for management. The aim of this study is to assess the effect of active repositioning treatment at infants with positional skull deformities. Method: A retrospective data of 158 infants treated with active repositioning as a conservative treatment for at least 2 months were analyzed in this study. Anthropometric 3D scanner measurements of pre-and post-treatment diagonal difference, cranial vault asymmetry index, cranial ratio were evaluated for each patient. Infants were separated to 4 different groups according to their morphologic deformation types as plagiocephaly, brachycephaly, scaphocephaly and combined (brachycephaly+plagiocephaly), and 2 groups according to age at onset of treatment. Results: In combined group, pre-treatment mean diagonal difference and cranial vault asymmetry index values decreased from 9.38 mm and 6.9% to 6.94 mm and 4.9% respectively. In plagiocephaly group, mean pre-treatment results changed from 10.32 mm and 7.5% to 7.83 mm and 5.5% respectively after treatment. All these changes were statistically significant. Effectiveness of timing of repositioning treatment on different positional skull deformities was analyzed and outcome was found significantly improved when the active repositioning treatment was started before 4 months of age. Conclusion: Improvement rates of the asymmetry decrease with age due to decreasing skull enlargement rate. Early diagnosis, especially before 4 months of age, more parental education, and close follow-up are important for babies with this condition who may benefit just from repositioning treatment.
The role of age on helmet therapy in deformational plagiocephaly and asymmetric brachycephaly
(2020) Cevik, Serdar; Isik, Semra; Ozkilic, Alper; 0000-0002-6929-7135; 31482314; K-6580-2015
Purpose This study aimed to investigate the effect of age at helmet therapy onset on treatment efficacy in moderate-to-severe deformational plagiocephaly (DP) and combined DP and asymmetrical brachycephaly (AB) in infants. Methods Ninety-eight infants who were referred to our institution and who underwent helmet therapy between 2014 and 2018 were retrospectively reviewed. Patients with DP [cranial vault asymmetry index (CVAI) > 7% and DD > 10 mm] and AB [CVAI > 7% and cephalic ratio (CR) >= 94] were included. Pre- and post-treatment calvarial asymmetries (difference among DD, CVAI, and CR) were measured using 3D screening systems (SmartSoc and Omega Scanner 3D). Infants were classified according to age at treatment onset: group 1 (age, < 6 months) and group 2 (age, >= 6 months). Results CVAI was statistically different between treatment onset and end in subgroups. Moreover, the regression of CVAI between groups DP1 (- 7.5% +/- 1.2%) versus DP2 (- 5.4% +/- 1.5%; p = 0.001) and groups AB1 (- 6.6% +/- 1.4%) versus AB2 (- 4.4 +/- 2.5; p = 0.0013) was statistically significant. CVAI was < 3.5% and CR was <= 89 (assumed as normal cranial shape) after treatment in 48%, 40%, 32%, and 6% of infants in groups DP1, DP2, AB1, and AB2, respectively. Conclusion These findings emphasize the efficacy of helmet therapy for DP and AB. Helmet is an appropriate treatment option particularly for infants with severe DP and AB, and early onset of helmet therapy before the age of 6 months is advised.
