A profile of traumatic spinal cord injury and medical complications in Latvia

Study design: A single centre retrospective study. Objectives: To collect data and analyse the epidemiological profile of traumatic spinal cord injury and its medical complications during the subacute rehabilitation period. Setting: Spinal Cord Injury Rehabilitation Programme of the National Rehabilitation Centre, 'Vaivari', Jurmala, Latvia. Methods: Information was collected in 2015 from the medical records of 134 patients with a traumatic spinal cord injury admitted for primary rehabilitation between January 2011 and December 2014. Results: During this period, the median age of patients with a traumatic spinal cord injury was 39.5 years, and the male to female ratio was 5:1. The leading causes of traumatic spinal cord injuries were falls (37%), road traffic accidents (29%), sport and leisure activities (19%), other cause (8%), unidentified causes (5%), and assault (2%). The most common medical complications were pain (77%), spasticity (48%), urinary tract infections (45%), pressure ulcers (25%), and orthostatic hypotension (14%). Conclusions: Preventive measures in Latvia should be aimed primarily to address falls, road traffic accidents, and sport and leisure activities in the young male population. Medical complications are varied, and they are an important factor following traumatic spinal cord injury. The results obtained in this study comply with the data from studies in countries of the Baltic and North Sea regions of Europe.publishersversionPeer reviewe

Insufficient assessment of sexual dysfunction : A problem in gynecological practice

Background and Objective: Sexual health is an important part of a woman's life and well-being. Female sexual dysfunction is a complicated problem, it is often underestimated in the healthcare process, and its management is complex. Giving women the opportunity to talk about sexual problems is a fundamental part of healthcare and may improve their quality of life. The aim of this study was to find out patients' experience and attitudes toward the involvement of gynecologists addressing sexual issues, to disclose the main barriers to initiate a conversation, and to assess the prevalence of sexual disorders among patients in a gynecological clinic. Material and Methods: A questionnaire-based approach was used to survey 18- to 50-year-old voluntary patients in the gynecological clinic. The study population comprised 300 different gynecological (except oncologic) patients independently of reasons for being in the clinic. The duration of the study was 6 months. Results: Only one-third of the patients had ever been asked about their sexual life by a gynecologist, whilst the majority (80%) of the respondents reported they would like to be asked and discuss sexual issues. The patients mostly did not complain because of psychoemotional barriers, and shame was the main barrier for patients to talk about their problems. Sexual dysfunction was a frequent disorder among gynecological patients, reaching especially high levels in the arousal (46.41%) and lubrication (40.67%) domains. Conclusions: The assessment of sexual health is insufficient in gynecological care, and sexual history-taking and evaluation of sexual functions should be included in routine gynecological health assessments.publishersversionPeer reviewe

Evaluation of axonal optic nerve damage using visual evoked potentials and optical coherence tomography in patients with multiple sclerosis

Background and Objective: Axonal tissue impairment plays a substantial role in the development of disability in multiple sclerosis. The aim of our study was to analyze the clinical utility of visual evoked potentials (VEP) and optical coherence tomography (OCT) in the diagnosis of optic nerve axonal damage and to determine the correlation between the retinal nerve fiber layer at the temporal quadrant (RNFLT) thickness and the VEP amplitude in multiple sclerosis patients with and without a history of acute optic neuritis (ON). Material and Methods: This cross-sectional study included 69 relapsing-remitting patients with multiple sclerosis from Pauls Stradins Clinical University Hospital, who were divided into 2 groups: with and without a history of ON. The RNFLT thickness and the VEP amplitude were measured. Results: A total of 25 clinically affected eyes were studied. VEP showed a higher sensitivity (64%) than OCT (50%) in supporting a clinical diagnosis of ON. A significant correlation was found between the RNFLT thickness in the temporal segment and the average VEP amplitude both in the eyes of MS patients with (rs=0.42, P=0.01) and without a history of ON (rs=0.44, P<0.001). Conclusions: The evidence from this study suggests that diagnostics of optic nerve axonal damage is feasible by means of using the average VEP amplitude instead of OCT alone. However, the combination of VEP and OCT increases the chance to confirm the existence of ON. A significant correlation was found between structural and functional vision parameters for both patients with and without a history of ON.publishersversionPeer reviewe

Influence of severe carotid stenosis on cognition, depressive symptoms and quality of life

Publisher Copyright: © 2017 Pucite et al.Background: Carotid artery disease is not just a causal risk factor of ischemic stroke, but may predispose patients to depressive symptoms and low health related quality of life (HRQoL). Objectives: The objectives of the present study were to assess the association between severe carotid artery stenosis (CAS) and cognitive impairment, frequency of depressive symptoms and status of HRQoL. Methods: Cross - sectional study involved 55 patients with severe CAS and 54 patients with lower extremity peripheral artery disease (PAD). Cognitive impairment was assessed using Montreal Cognitive Assessment Scale (MoCA), depressive symptoms - PHQ-9 scale. HRQoL was measured using Medical Outcome Survey Short Form version 2 (SF-36v2). Results: Median MoCA score 24 [23;26] was significantly lower in patients with severe CAS than in patients with PAD - 26 [25-28],(p=0.005; effect size r=0.3). There was no statistically significant difference of median PHQ-9 scores the in CAS group (median PHQ-9 score 4.0 [5]) and in the PAD group (median PHQ-9 score 5.5 [7]), (p=0.08, effect size r=0.18). Mean SF-36v2 scores were similar in CAS and PAD groups except for bodily pain (p=0.001, Cohen's d value = 0.77) and vitality (p=0.02, Cohen's d value = 0.49). Conclusion: In summary, our findings indicate that severe CAS could play a role in cognitive decline. Further studies should be conducted using larger patient cohorts without ischemic brain lesions and with balanced vascular risk profiles to investigate impact of CAS on cognition. There was no association between severe CAS and depressive symptoms in the present study. As patients with severe CAS did not exhibit physical symptoms, HRQoL was better for those patients than for patients with lower extremity PAD.publishersversionPeer reviewe

Functional and Structural Evaluation of Afferent Visual System in Multiple Sclerosis Patients

Publisher Copyright: © 2015 by Daina Pastare.There is insufficient information about the progress and variability of multiple sclerosis (MS). Afferent visual pathways are an appropriate MS clinical model. Optical coherence tomography (OCT) allows to perform precise measurements of axonal tissue in the retinal nerve fibre layer (RNFL). Visual evoked potentials (VEP) provide information about the functional status of visual pathways. The aim of our study was to use OCT and VEP to evaluate MS patients with and without optic neuritis (ON) history and to determine relationships between functional and structural changes. The cross-sectional study included 76 relapsing-remitting MS patients and 28 healthy controls. The lowest mean VEP N75/P100 amplitude was found in ON affected eyes (8.16 mkV, SD = 4.60). However, it was observed that the mean amplitude in patients without ON (M = 9.86; SD = 4.63) was by 4.64 mkV lower than in controls (p 0.001) between RNFLT and mean P100 latency. In summary, we found that deterioration in the visual system was not associated with the clinical ON episode. Regardless of ON symptoms in history, there exists correlation between functional and structural changes.publishersversionPeer reviewe

A population based study of multiple myeloma patients with medication-related osteonecrosis of the jaw

Žurnāla mājaslapā pie raksta norādītas RSU afiliācijas, bet Scopus datubāzē Latvijas Universitātes afiliācijas.OBJECTIVE: Medication-related osteonecrosis of the jaw (MRONJ) is a rare complication of antiresorptive or antiangiogenetic therapy that manifests as an exposed bone with clinical signs of infection, persisting for more than 8 weeks, without history of radiation therapy or metastases to the jaws. The aim of the study was to describe the incidence, risk factors, staging process and clinical course of MRONJ in patients with multiple myeloma (MM). MATERIALS AND METHODS: We retrospectively analyzed all (126) newly diagnosed MM patients at Riga East Clinical University Hospital (Riga. Latvia) from June 2014 to June 2017. RESULTS: Among 88 MM patients treated with bisphosphonates (BP), 6 (6.8%) patients developed MRONJ. All six patients received intravenous nitrogen-containing BPs. The average time until MRONJ manifestation was under two years. For our patients the severity of MRONJ was stage I in two, stage II in three, and stage III in one patient. Five patients had MRONJ of mandibula and one of maxilla. All patients with MRONJ had undergone a dental extraction or a trauma before the development of MRONJ. CONCLUSION: We found that MRONJ correlated with the patient's age. The average time until MRONJ manifestation in reserach group is 2 years. One of triggerring MRONJ factors are tooth extraction or trauma.publishersversionPeer reviewe

An Overview of Adenoid Microbiome Using 16S rRNA Gene Sequencing-Based Metagenomic Analysis

Background and Objectives: the upper respiratory tract harbors the highest bacterial density in the whole respiratory system. Adenoids, which are located in the nasopharynx, are a major site of bacterial colonies in the upper airways. Our goal was to use culture-independent molecular techniques to identify the breadth of bacterial diversity in the adenoid vegetations of children suffering from chronic rhinosinusitis and obstructive sleep apnea. Materials and methods: in total, 21 adenoid samples were investigated using amplification and sequencing of the V3-V4 hypervariable region of the bacterial 16S rRNA gene. Results: among the most common bacterial species found were Veillonella atypica, Fusobactrium nucelatum, Shaalia odontolytica, and Moraxella catarrhalis. Veillonella atypica and Fusbacterium nucelatum dominated the microbiome in all 21 samples, attributing to more than 60% of all detected genetic material. Conclusions: since both Veillonella atypica and Fusobacterium nucleatum are, predominantly, oral cavity and dental microorganisms, our findings may suggest oral microbiome migration deeper into the oropharynx and nasopharynx where these bacteria colonize adenoid vegetations.publishersversionPeer reviewe

Solar retinopathy: a new setting of red, green, and blue channels

Purpose: To introduce a new color imaging technique using improved settings of red, green, and blue channels for improved delineation of retinal damage in patients with solar retinopathy. Method: A retrospective case series of patients with poor vision secondary to solar retinopathy were analyzed. All patients underwent visual acuity, refraction, and dilated fundus examination. A spectral domain–optical coherence tomography of the macula and color fundus imaging using optimized red, green, and blue color setting was performed. Patients were reviewed over a 6-month period. The data were analyzed for statistical significance using an independent t test and a receiver operating characteristic curve. Results: In total, 20 eyes of 10 patients were included between 2009 and 2017. The mean age was 24.9 ± 18.1 years. Best corrected visual acuity at first consultation was 0.78 ± 0.11 and after 6 months was 0.83 ± 0.09. Spectral domain–optical coherence tomography demonstrated retinal abnormalities at the myoid zone, ellipsoid zone, and the outer segment of photoreceptors. Receiver operating characteristic curve analysis showed an improving effect (area under the curve = 0.62; 95% confidence interval = 0.42–0.79). The color channels parameters, which improve visualization of the lesions were found to be 67-0.98-255 for the R-guided setting, 19-0.63-121 for the B-guided setting, and 7-1.00-129 for the G-guided setting. The ideal red, green, and blue setting was in 24-0.82-229. Conclusion: The use of a new setting of red, green, and blue channels could improve the diagnosis and monitoring of solar retinopathy, hence improving patient care
