AIM: To analyze the demographic and clinical data of preterm or low birth weight newborns with periventricular hemorrhage. MATERIAL and METHODS: This retrospective study analyzed patients admitted to the neonatal intensive care unit of a Bahcesehir University School of Medicine -Affiliated Hospital due to preterm birth or low birth weight between June 1, 2012, and April 30, 2021. Categorical values were evaluated by Pearson chi-square or Fisher's exact test. The Mann -Whitney U test compared continuous values between the groups. Logistic regression was used to evaluate the factors that affected permanent cerebrospinal fluid (CSF) diversion. RESULTS: The study finally evaluated 180 newborns. Ninety-one newborns (50.5%) had grade I, 18 (10%) had grade II, 22 (12.2%) had grade III, and 49 (27.2%) had grade IV hemorrhage. One hundred and forty-nine patients (82.8%) were delivered by cesarean section, and 31 (17.2%) were delivered vaginally. All patients with low-grade hemorrhage who needed temporary CSF diversion eventually required permanent CSF diversion. For high-grade hemorrhage, 15 (grade III, 1; grade IV, 14) of 51 (29.4%) patients with ventricular access device (VAD) insertion required permanent CSF diversion. Fifteen (grade III, 6; grade IV, 9) of these 51 (29.4%) patients did not need permanent CSF diversion; thus, their VADs were removed. CONCLUSION: The permanent CSF diversion rate was significantly higher in the high-grade hemorrhage group, which had significantly lower weight and gestational age at birth. Moreover, only weight at VAD insertion had minimal effect on the need for permanent CSF diversion.

Introduction: Deep brain stimulation (DBS) is a standard surgical treatment method which is generally applied to subthalamic nucleus in Parkinson's patients in cases where medical treatment is insufficient in treating the motor symptoms. It is known that Subthalamic Nucleus Deep Brain Stimulation (STN-DBS) treats many motor symptoms. However, the results of studies on speech and voice vary. The aim of the study is analysing the effect of STN-DBS on the characteristics of voice. Materials/methods: A total of 12 patients, (8 male-4 female) with an age average of 58.8 +/- 9.6, who have been applied DBS surgery on STN included in the study. The voice recordings of the patients have been done prior to surgery and 6 months after the surgery. The evaluation of voice has been carried out through the instrumental method. The patients' voice recordings of the /a,e,i/ vowels have been done. The obtained recordings were evaluated by the Praat programme and the effects on jhitter, shimmer, fundamental frequency (F0) and noise harmonic rate (NHR) were analysed. Results: Numerical values of F0 of all female participants have been decreased for all of the vowels postoperatively. In the females; jhitter and fraction parameters were found to be significantly different (0.056 and 0.017, perspectively) for the vowel /e/. In addition, p values in the shimmer for vowels /e,i/ were thought to be clinically significant (.087, .079 and .076) respectively. All these changes in second measurements were found to indicate worsening vocal quality after the DBS in females. In males, there is not any significant difference observed between two measures in any of the parameters of any vowels. Conclusions: Acoustic voice quality deteriorated after STN-DBS predominantly for females however this deterioration was not prominent audio-perceptually. This finding commented as a result of the fact that that voice quality deviance of the participants was not severe.
