The Co-Occurrence of Post-Traumatic Stress Disorder and Depression in Individuals with and without Traumatic Brain Injury: A Comprehensive Investigation.

Post-traumatic stress disorder (PTSD) is a prevalent psychiatric disorder that often occurs following war trauma. Despite its high prevalence, there is still a lack of comprehensive understanding regarding the mechanisms underlying its progression and treatment resistance. Recent research has shed light on the biological basis of PTSD, with neuroimaging studies revealing altered brain connectivity patterns in affected individuals. In war contexts, traumatic brain injury (TBI) is a common occurrence and is associated with a high prevalence of PTSD. This study aimed to compare the severity of PTSD and depression in patients with and without a history of TBI to shed light on the impact of comorbid TBI on the presentation of PTSD symptoms. To achieve this goal, a cross-sectional study was conducted involving a sample of 60 outpatients who were diagnosed with both PTSD and Depressive Disorder. The inclusion criteria required participants to meet the diagnostic criteria for both disorders using validated tools. The severities of PTSD and depressive symptoms were assessed using scales that have been widely used and validated in previous research. By utilizing these standardized assessment tools, this study aimed to ensure the reliability and validity of the obtained data. The results of this study revealed that patients with comorbid PTSD and TBI exhibited a significantly higher severity of PTSD symptoms compared to those with PTSD only. Specifically, the comorbid group demonstrated higher ratings of symptom intensity across all symptom clusters. These findings are consistent with previous research that has highlighted the impact of comorbid TBI on the intensity and persistence of PTSD symptoms. When controlling for PTSD severity, no significant differences were observed in the severity of depressive symptoms between the two groups. This suggests that the increased depressive symptoms observed in the comorbid group may be primarily driven by the presence of more intense PTSD symptoms rather than TBI per se. The findings highlight the need for an accurate diagnosis of TBI in individuals with PTSD to guide appropriate treatment interventions. Further research is warranted to delve into the underlying mechanisms that contribute to the interaction between TBI and PTSD and to develop targeted interventions for individuals with comorbid PTSD and TBI.

Association between Circle of Willis Configuration and Rupture of Cerebral Aneurysms.

Background and Objectives: Intracranial hemorrhage caused by the rupture of brain aneurysms occurs in almost 10 per 100,000 people whereas the incidence of such aneurysms is significantly higher, accounting for 4-9%.Linking certain factors to cerebral aneurysm rupture could help in explaining the significantly lower incidence of their rupture compared to their presence. The aim of this study is to determine the association between the corresponding circle of Willis configurations and rupture of cerebral aneurysms. MATERIALS AND METHODS: A group of 114 patients treated operatively for aruptured cerebral aneurysm and a group of 56 autopsied subjects were involved in the study. Four basic types of the circle of Willis configurations were formed-two symmetric types A and C, and two asymmetric types B and D. RESULTS: A statistically significantly higher presence of asymmetry of the circle of Willis was determined in the group of surgically-treated subjects (p = 0.001),witha significant presence of asymmetric Type B in this group (p < 0.001). The changeson the A1 segment in the group of surgically-treated subjects showed a statistically significant presence compared to the group of autopsied subjects (p = 0.001). Analyzing the presence of symmetry of the circle of Willis between the two groups, that is, the total presence of symmetric types A and C, indicated their statistically significant presence in the group of autopsied patients (p < 0.001). CONCLUSIONS: Changes such as hypoplasia or aplasia of A1 and the resulting asymmetry of the circle of Willis directly affect the possibility of the rupture of cerebral aneurysms. Detection of the corresponding types of the circle of Willis after diagnostic examination can be the basis for the development of a protocol for monitoring such patients.

Factors affecting the survival of patients with glioblastoma multiforme.

PURPOSE: Glioblastoma multiforme (GBM) is the most aggressive malignant tumor in the brain and no therapy can achieve full recovery/cure. The aim of this study was to identify which factors could improve the survival of operated patients, and to determine which kind of therapy was most successful. METHODS: The study was conducted at the Clinic for Neurosurgery in Nis, Clinical Centre Nis and the Oncology Institute, Clinical Center Nis. A cohort of patients who underwent surgery between January 2013 and December 2015 was studied and continuous monitoring of survival lasted until June 2017. RESULTS: Patients who underwent only biopsy have 3.82- fold greater chance of death than patients with complete tumor resection (HR 3,825; p=0.001). Karnofsky performance status score significantly affected survival (preoperatively and postoperatively; p<0.001). Apart from radiotherapy, three types of chemotherapy were applied: carmustine (BCNU) - 32.80% of the patients, procarbazine/lomustine/ vincristine (PCV) - 38.80% and temozolomide - 28.40%. Kaplan-Meier overall survival showed that patients treated with temozolomide had the longest survival compared to patients treated with BCNU and/or PCV chemotherapy. CONCLUSION: The best prognosis was seen in those patients who had complete tumor resection. Patients treated with temozolomide had the best survival compared with those treated with BCNU and PCV chemotherapy.

Predictors of Mortality in Long-Term Follow-Up of Patients with Terminal Alcoholic Cirrhosis: Is It Time to Accept Remodeled Scores?

OBJECTIVE: To identify the prognostic score that is the best predictor of outcome in patients hospitalized with decompensated liver cirrhosis. MATERIAL AND METHODS: In this prospective study, 126 patients were enrolled and followed up for 29 months. For each patient, prognostic scores were calculated; these included the Child-Turcotte-Pugh score (CTP score), CTP creatinine-modified I score, CTP creatinine-modified II score, Model for End-Stage Liver Disease (MELD score), MELD model for end-stage liver disease sodium-modified score, Integrated MELD score, updated MELD score, United Kingdom MELD, and the MELD score remodeled by serum sodium index (MESO index). Cox regression analysis was used to assess the ability of each of the scores for predicting mortality in patients with alcoholic cirrhosis. Their discriminatory ability was evaluated using receiver operating characteristic (ROC) curve analysis. RESULTS: The updated MELD score had the highest predictive value (3.29) among the tested scores (95% CI: 2.26-4.78). ROC curve analysis demonstrated that the MELD score of 22.50 (AUC = 0.914, 95% CI: 0.849-0.978; p < 0.001) had the best discriminative ability for identifying patients with a high risk of mortality; the next best was the MESO index of 16.00 (AUC = 0.912, 95% CI: 0.847-0.978; p < 0.001). CONCLUSION: The risk of mortality was highest in patients with the highest updated MELD score, and those with MELD scores >22.50 and a MESO index >16.00.

Aseptic intrafascial and extrafascial abscesses 10 years after a 2-level DIAM insertion procedure.

With the aim to prevent the so-called adjacent-segment disease in spinal fusion surgery and to serve as the primary surgical procedure for the management of low-back pain syndrome or neurogenic claudication in spinal stenosis, the so-called dynamic spine stabilization is applied using specifically designed implants: interspinous spacers, such as DIAM (Device for Intervertebral Assisted Motion), Coflex, and X-stop. It is commonly accepted that interspinous spacers are made from material that is well tolerated by the body, that their placement is simple, that complications are rare, and that they can greatly benefit the patients. So far, there have not been published studies reporting infective or other complications 10 or more years after the placement of DIAM spacers. The aim of this paper was to present a case of an extremely late complication (after 10 years) in the form of intra- and extrafascial dumbbell abscesses, concomitantly appearing at both levels treated with the DIAM spacer. The paper presents the existence of a significant correlation between CT and MRI findings as well as the deterioration in Oswestry Disability Index and visual analog scale scores. Over time, dynamic spine stabilization might possibly impact reactive accumulation of sterile fluid in the vicinity of an implant and could therefore be related to delayed complications even 10 years after surgery. The finding of a growing layer composed of thick aseptic fluid around the DIAM implant, with a simultaneous occurrence of spinous process osteolysis and formation of a mineralized pseudocyst, bears a considerable risk of delayed inflammatory complications, including abscess, and therefore requires the explantation of the DIAM implant.

Cervical epidural hematoma: case report.

INTRODUCTION: Cervical epidural hematoma is a rare phenomenon in children. MRI scan of the cervical spine is the method of choice in establishing diagnosis and a quick evacuation of hematoma and de- compression. CASE OUTLINE: We present a case of 11-year-old boy whose lower extremities were paralysed after a trivial injury of the cervical spine which he sustained while playing. Seven days after the injury, severe clinical symptoms appeared, and MRI of the spine showed the presence of cervical epidural hematoma. CONCLUSION: Cervical epidural hematoma in children is very rare. Adequate neurological examination, di- agnostics and urgent surgical intervention are of paramount importance for accomplishing good results. Early and persistent rehabilitation are the condition for achieving maximal recovery.

The activities of acid DNase and 5'nucleotidase in erosive reflux esophagitis and Barrett's epithelium.

BACKGROUND/AIMS: The study examines the relationship between activity of acid DNase and 5'nucleotidase (5'NT) and histological changes in reflux esophagitis. METHODOLOGY: Thirty-three patients were examined, 15 of whom with mild esophagitis, 12 with severe esophagitis and 6 with Barrett's epithelium. Patients were classified into 3 groups, according to Ismail-Beigi histological criteria: mild esophagitis group (ME); severe esophagitis group (SE); Barrett's esophagitis group (BE). DNase and 5'NT levels were measured biochemically both in healthy and injured tissue samples. RESULTS: Difference of acid DNase and 5'NT activity in healthy tissue versus injured tissue samples was the lowest in ME group: 0.55±4.47 U/g for acid DNase and 11.56±37.11 U/g for 5'NT, the difference increased to 4.43±1.64 U/g for acid DNase and 105.57±54.11 U/g for 5'NT in the SE group, while 6.07±2.92 U/g for acid DNase and 109.83±14.02 U/g for 5'NT as the highest levels were measured in the BE group. Difference in BE group is statistically significantly higher (p <0.05) compared to the ME group, confirmed by ANOVA with Dunnett's post hoc test. CONCLUSIONS: The study shows significant decrease of apotosis level that is detectable even before metaplasia was morphologically defined.

[Assessment of clinical depression comorbid with posttraumatic stress disorder].

BACKGROUND/AIM: Comorbidity of the posttraumatic stress disorder (PTSD) and depression is often recognized in the clinical practice. The aim of the paper was to determine the severity of depression and the group of symptoms which are the most prominent in clinical depression comorbid with PTSD. METHODS: Totally 60 patients were assessed and divided into the experimental and control group using the Structured Clinical Interview for DSM-IV Axis I Disorders, Investigator Version (SCID-I, modified) (SCID for DSM-IV) and ICD-10 diagnostic criteria. The presence and the severity of the disorders were assessed by means of the following intruments: Clinician-Administrated PTSD Scale for DSM-IV (CAPS-DX), Montgomery-Asberg Depression Rating Scale (MADRS) and 17-item Hamilton Rating Scale for Depression (HAMD). The differences between groups were evaluated using Student t test and by means of the correlational analysis of the data with p < 0.05. RESULTS: The obtained results showed that depression which was comorbid with PTSD was of significant clinical severity with 31.20 score on HAMD and 30.43 score on MADRS in PTSD-D group. The group of the symptoms: lassitude, inability to feel, suicidal thoughts and inner tension contributed mostly to the global severity of the comorbid clinical depression on MADRS. The group of the symptoms: suicide and somatic symptoms, gastrointestinal, guilt, hypochondriasis, work and activity, anxiety psychic, agitation, and weight loss, genital symptoms and anxiety somatic contributed mostly to the global severity of comorbid clinical depression on HAMD. The average score was 16.03 and 16.97 on HAMD and MADRS, respectively in PTSD group. CONCLUSION: Depression which is comorbid with posttraumatic stress disorder represents significant clinical entity with domination of the different groups of symptoms between the groups PTSD and PTSD-D on HAMD. Identification of aforementioned severity of illness and delineated group of symptoms lead the clinician to establish the diagnosis of depression, reduce the risk of diagnostic ommition of the depression and enable the clinician to chose the optimal treatment method for the delineated disorders.
