Participants with restricted dominant shoulder internal rotation range of motion demonstrate no side-to-side difference in humeral head translation; and no difference before and after joint mobilization: a pilot study.

[Purpose] To compare humeral head translation (HHT) during shoulder elevation between dominant and non-dominant shoulders in participants with limited dominant shoulder internal rotation range of motion (ROM). To determine if joint mobilization alters HHT, and if relationships exist between the bicipital forearm angle and HHT. [Participants and Methods] Fifteen (9 female) participants (age 25.7 ± 6.8 years) with a minimum 15-degree dominant shoulder internal rotation ROM deficit compared to the opposite shoulder participated. All participants underwent bicipital forearm angle (BFA) measurements and ultrasound imaging to measure acromiohumeral and posterior glenohumeral distances in 3 positions: Resting, 90 degrees of shoulder flexion, and 60 degrees of shoulder abduction with full external rotation. Ultrasound images were used to calculate HHT. Participants' dominant shoulders underwent posterior glide mobilization, followed immediately by repeated ultrasound images and ROM measures. [Results] There was no dominant to non-dominant shoulder, or before and after mobilization HHT differences. No correlations existed between bicipital forearm angles and HHT or ROM gains after mobilization. [Conclusion] Participants with internal rotation ROM loss demonstrated symmetrical HHT. Joint mobilization increased ROM, but HHT was unchanged. No relationships existed between BFA and HHT.

Clinical and histopathological characteristics of primary focal segmental glomerulosclerosis in Turkish adults.

The data regarding primary FSGS (pFSGS) from different parts of the world differ. While the prevalence of pFSGS has been increasing in Western countries like the USA, it follows an inconsistent trend in Europe and Asia and a decreasing trend in Far Eastern countries such as China in the last two decades. There are undetermined factors to explain those national and geographic discrepancies. Herein, we aimed to reveal the current prevalence with clinical and histopathological characteristics of pFSGS in Turkish adults. This study includes the biopsy-proven pFSGS patients data recorded between 2009 and 2019, obtained from the national multicenter primary glomerulonephritis registry system of the Turkish Society of Nephrology Glomerular Diseases (TSN-GOLD) database. 850 of the 3875 primer glomerulonephritis patients(21.9%) have pFSGS. The mean age is 40.5 ± 14.2 and 435 (51.2%) of patients are male. Nephrotic syndrome is the most common biopsy indication (59.2%). 32.6% of patients have hematuria, 15.2% have leukocyturia and 7.8% have both. Serum creatinine, albumin, and proteinuria are 1.0 mg/dL (IQR = 0.7-1.4) mg/dl, 3.4 ± 0.9 g/dl, 3400 mg/day(IQR, 1774-5740), respectively. Females have lower mean arterial pressure (- 2.2 mmHg), higher eGFR (+ 10.0 mL/min/1.73 m2), and BMI (+ 1.6 kg/m2) than males. Thickened basal membrane(76.6%) and mesangial proliferation (53.5%) on light microscopy are the major findings after segmental sclerosis. IgM (32.7%) and C3 (32.9%) depositions are the most common findings on immunofluorescence microscopy. IgM positivity is related to lower eGFR, serum albumin, and higher proteinuria. The prevalence of pFSGS is stable although slightly increasing in Turkish adults. The characteristics of the patients are similar to those seen in Western countries.

Favorite colors of patients with drug-resistant epilepsy: pilot study.

OBJECTIVE: To evaluate the favorite colors of patients with drug-resistant epilepsy. METHODS: Following examination, 50 patients were diagnosed in accordance with the 2005 proposal of the International League Against Epilepsy and the definition of drugresistant epilepsy since 2010. The favorite color examination used a six-color tape and Trycolors, an online color mixing tool. The patients' color preferences were compared with those of 50 individuals without epilepsy. RESULTS: Patients with drug-resistant epilepsy preferred the color blue the most (30%), significantly more yellow (p = 0.0001), and significantly less green (p < 0.0001) compared to individuals without epilepsy. By mixing these colors at a certain percentage, we obtained the Go Ben color. SIGNIFICANCE: This information on preferred colors can help to improve compliance and can be utilized in designing medications and environments for patients with epilepsy.

Comment on "Posterior reversible encephalopathy syndrome in a patient with metastatic breast cancer: A case report".

Posterior reversible encephalopathy syndrome (PRES) is a neurotoxic encephalopathic state, manifesting clinical symptoms of headache, altered consciousness, visual disturbances, and seizures. Although several diseases have been identified as causative of PRES, the underlying mechanism remains unclear. Song et al recently published "Posterior reversible encephalopathy syndrome (PRES) in a patient with metastatic breast cancer: A case report" in the World Journal of Clinical Cases, highlighting and discussing the role of hypercalcemia in PRES as related to uncontrolled hypertension. To build upon this case description, we provide further insight into the possible underlying mechanisms of PRES through this commentary.

Clinical Accuracy of the Lateral-Anterior Drawer Test for Diagnosing Posterior Cruciate Ligament Rupture.

BACKGROUND: Commonly used clinical posterior cruciate ligament (PCL) tests present with diagnostic weaknesses requiring alternative clinical tests. The Lateral-Anterior Drawer test (LAD-test) is a suggested alternative that previously demonstrated concurrent validity in situ. Further in vivo LAD-test clinical accuracy examination is required prior to any recommendation for clinical adoption. Thus, this case-control study aims to (1) investigate the LAD-test's in vivo interrater and intra-rater reliability; (2) establish LAD-test concurrent validity against MRI as the reference standard; and (3) examine the correspondence between examiners' professional working experience and LAD-test diagnostic accuracy. METHODS: Three examiners with different professional experience levels, blindfolded during testing, and blinded from subjects' identity, medical history, and reference test outcome performed all LAD-testing twice per subject. Reliability analyses included percent agreement, Fleiss' kappa and Cohen's kappa coefficients with 95% Confidence Intervals (CIs) and prevalence-adjusted bias-adjusted kappa (PABAK) calculations. Validation parameters included sensitivity, specificity, likelihood ratios (LR + ; LR-), and predictive values (PPV; NPV) each accompanied by 95%CIs; each tester's percent agreement with the MRI; and their Youden Index. RESULTS: The study sample was comprised of 31 subjects of which 14 had a history of unilateral full-thickness PCL-rupture. Their 14 contralateral knees and both knees of 17 healthy subjects served as controls. In vivo LAD-test performance did not produce any negative ramifications for the tested subjects. Interrater reliability was moderate (test-1: Fleiss'κ = 0.41; 95% CI 0.40;0.41; test-2:Fleiss'κ = 0.51; 95% CI 0.50;0.51). Pairwise examiner's LAD-test outcome agreement ranged from 74 to 89%. Pairwise interrater reliability was fair-to-substantial (κ = 0.27 to κ = 0.65) with moderate-to-substantial PABAK (0.48-0.77). Intra-rater reliability was substantial-to-almost perfect (PABAK 0.65-0.97). Sensitivity and specificity ranged from 57 to 86% and 83 to 98%, respectively. The advanced and novice clinicians' Youden Indexes were acceptable. The same examiners' positive likelihood ratios revealed important and relative important effects, respectively. Positive predictive values were considerable for the advanced and novice clinicians, while negative predictive values were high for all examiners. CONCLUSION: Overall, the study results suggested LAD-test practicability. In vivo LAD-test performance did not produce any negative ramifications for the tested subjects. In subjects presenting with a chronic PCL-deficiency (i.e., > 3 months since initial injury), the LAD-test's clinical accuracy was comparable-to-superior to other commonly used clinical PCL-tests. Future studies to establish the LAD-test's usefulness in isolation as well as in combination with other clinical tests for acute PCL-rupture diagnostics are warranted. TRIAL REGISTRATION NUMBER: DRKS00013268 (09. November 2017).

Sleep Disorders in Acute Stroke.

Background: Stroke patients have sleep-wake disorders, mostly in form of insomnia, excessive daytime sleepiness/fatigue, or hypersomnia (increased sleep needs). Objective: The aim of this study was to analyze types of sleep disorder (SD) and their frequency in patients with sleep apnea and acute stroke in relation to the type of stroke and side of lesion. Methods: The study analyzed 110 patients with sleep apnea and acute stroke hospitalized in the Clinic of Neurology, University Clinical Centre Tuzla. Acute stroke has been verified either by computerized tomography or magnetic resonance imaging of the brain. SD was verified according to the Berlin Questionnaire Test, The Epworth Sleepiness Scale, The Stanford Sleepiness Scale and the General sleep questionnaire. Strokes were divided by: a) type, into hemorrhagic and ischemic, and b) the localization of the stroke, to right and left cerebral hemispheres. Results: Of the total number of respondents, all had some sleep disorder. 20% of respondents had severe level of SD, 35.4% moderate, 37.3% moderate- severe and 7.3% mild problems. There were no statistically significant differences in the frequency of SD among patients with ischemic and hemorrhagic stroke (p = 0.58). In relation to the side of lesion, there was more patient with SD and stroke in the both sides, but there were no statistically significant differences (X2=1.98, p=0.161). According Epworth Sleepiness Scale, Stanford Sleepiness Scale and Berlin Questionnaire test snoring was present in 81% and daytime sleepiness in all patients. Conclusion: SD as a neuropsychological disorder has a significant incidence in the acute phase of stroke in patients with sleep apnea. Sleep disorder is more common in ischemic stroke and stroke in the both hemisphere, but it is not statistically significant difference. Daytime sleepiness, fatigue and snoring are the most common sleep problems in patients with acute stroke and apnea, but it is not statistically significant.

Memory efficiency in patients with drug-resistant epilepsy.

OBJECTIVE: To evaluate memory in patients with drug-resistant epilepsy. METHODS: Following an examination, 50 patients were diagnosed in accordance with the 2005 proposal of the International League Against Epilepsy and the definition of drug-resistant epilepsy from 2010. The neuropsychological examination used the Wechsler Memory Scale. It assessed seven structural types of memory: general knowledge, orientation, mental control, logical memory, number memory, associative memory, and visual reproduction. The values were compared with 50 subjects without epilepsy. RESULTS: Patients with epilepsy had statistically significantly lower values in five of seven structural units of memory. The average value of overall memory efficacy in subjects with epilepsy was 96.5 ± 19.6, while in subjects without epilepsy it was 118 ± 15.6 (p = 0.0002). Memory impairments are greater in those taking polytherapy (p = 0.0429). The overall memory efficiency correlated significantly negatively with seizure frequency (p = 0.0015) and insignificantly negative with the duration of epilepsy (p = 0.1935). CONCLUSION: Patients with drug-resistant epilepsy have lower memory efficiency. Memory impairments are greater in those taking polytherapy, as with those with more frequent seizures. The duration of epilepsy has no significant effect on overall memory performance.

Acute Stroke Patients with Sleep Apnea Acording to the Disability and Incidence of Relapse.

BACKGROUND: Sleep is a complex process involving the interactions of several brain regions, which play a key role in regulating the sleep process, particularly the brainstem, thalamus, and anterior basal brain regions. The process of sleep is accompanied by a change in body functions, as well as a change in cerebral electrical activity, which is under the control of the autonomic nervous system. OBJECTIVE: The aim of the study was to analyze the frequency of stroke recurrence and disability of patients with stroke and apnea. METHODS: It was analyzed 110 acute stroke patients with sleep apnea. All patients were evaluated with: Glasgow scale, The American National Institutes of Health Scale Assessment, Mini Mental Test, The Sleep and snoring Questionnaire Test, The Berlin Questionnaire Test, The Epworth Sleepiness Scale, The Stanford Sleepiness Scale, and The general sleep questionnaire. RESULTS: The largest number of patients with apnea on admission had a degree of disability of 4, and on discharge of 1. There was a statistically significant difference between the mean values of incapacity for admission and discharge. The student's t - test did not determine a statistically significant difference in disability according to the Rankin scale between patients with and without apnea at admission (t = 0.059, p = 0.95) and discharge (t = 0.71, p = 0.48). According to the NIHS scale, patients of both sexes with apnea had a neurological deficit of 7.55 ± 5.22 on admission and 7.1 ± 4.3 without apnea. Statistically significant difference was not found on the neurological deficit of both sexes, with and without apnea, at admission and discharge. With apnea, there were 13 relapses of stroke during one year, and without apnea in only 3 patients. CONCLUSION: Patients with acute stroke have a significantly higher correlation rate according to sleep apnea. There is no significant correlation in the degree of disability between patients with and without apnea.

Does Sleep Apnea Affect the Outcome of Stroke Patients?

BACKGROUND: Sleep apnea is described as an isolated risk factor for stroke or recurrent stroke which could be cause of death. In our study, the aim was to determine whether sleep apnea affects the outcome of stroke patients. SUBJECTS AND METHODS: This is a prospective study in which a group of 110 patients in the acute phase of a stroke was evaluated sleep apnea. Acute stroke has been diagnosed either by computed tomography and magnetic resonance imaging of the brain. There was no significant difference in patient's age with or without sleep apnea neither in men nor women. Neurological, neuropsychiatric, pulmonary test were performed in all patients at five different time periods. In these time periods, all patients were evaluated: Glasgow scale, The American National Institutes of Health Scale Assessment, Mini Mental Test, The Sleep and snoring Questionnaire Test, The Berlin Questionnaire Test, The Epworth Sleepiness Scale, The Stanford Sleepiness Scale and The general sleep questionnaire. RESULTS: One year after the onset of stroke, 91 (82.7%) of 110 patients with apnea survived. The survival rate of patients with sleep apnea is significantly lower than without sleep apnea (p=0.01). In men with apnea, the survival rate was significantly lower in patients without apnea (p=0.004). The largest number of survivors of apnea had diabetes mellitus, followed by survival of patients with heart disease, body mass index >29 kg/m2 and hypertension, with hyperlipoproteinemia and smoking. The highest number of survivors without apnea was body mass index >29 kg/m2, followed by survival of patients with hyperlipoproteinemia, heart disease, hypertension, smoking, and diabetes mellitus. CONCLUSION: Patients with sleep apnea have a significant correlation in survival rates compared with sexually and age-matched subjects, associated with concomitant risk factors such as hypertension, body mass index, and smoking.

Cognitive Functionality of Patients with Delirium after Stroke.

BACKGROUND: Delirium is a syndrome that occurs in all age groups and in many clinical departments, and is most common in intensive care units. It is an emergency, in the overlapping fields of somatic medicine, neurology and psychiatry. Delirium occurs suddenly, dramatically, and requires a quick reaction, recognition and treatment. There are only a small number of studies that have reported delirium after a stroke. In our study, the goal was to determine the cognitive functionality of patients with delirium after a stroke. SUBJECTS AND METHODS: This is a prospective study in which a group of 100 delirium patients in the acute phase of a stroke were evaluated for cognitive function. The control group consisted of the same number of patients with acute stroke who were not diagnosed with delirium. Neurological, neuropsychiatric and neuropsychological tests were performed in all patients at five different time periods. In these time periods, all patients were evaluated: Glasgow Coma Scale; Delirium Assessment Scale; The American National Institutes of Health Scale Assessment; Information-Memory-Concentration test; Dementia Score; Mini-Mental Test. The findings of computed tomography of the brain and magnetic resonance imaging of the brain were interpreted by a radiologist who was not familiar with the goals of this study. RESULTS: Cognitive functioning of delirious patients is statistically significantly worse after three and six months, and one year from stroke compared to those without delirium. There is no statistically significant difference in cognitive functioning between delirious patients in relation to gender, age, location and type of stroke and patients without delirium throughout one year from stroke. There is no significant difference in cognitive functioning between delirious patients during one year from stroke in relation to severity and type of delirium, and statistically significantly higher degree of cognitive dysfunction has those older than ≥65 years. CONCLUSIONS: Delirium significantly reduces the cognitive functioning of patients after a stroke.

Comparative Evaluation of Orthostatic Hypotension in Patients with Diabetic Nephropathy.

INTRODUCTION: Orthostatic hypotension (OH) affects 5-20% of the population. Our study investigates the presence of OH in diabetic nephropathy (DNP) patients and the factors affecting OH in comparison with nondiabetic chronic kidney disease (NDCKD) patients. METHOD: Patients presented to the nephrology clinic, and those who consented were included in the study. DNP was defined by kidney biopsy and/or clinical criteria. NDCKD patients of the same sex, age, and eGFR were matched to DNP patients. Demographic parameters and medications were obtained from the records. OH was determined by Mayo clinic criteria. The same researcher used an electronic device to measure blood pressure (BP). All samples were taken and analyzed the same day for biochemical and hematologic parameters and albuminuria. RESULTS: 112 (51 F, 61 M, mean age: 62.56 ± 9.35 years) DNP and 94 (40 F, 54 M, mean age: 62.23 ± 10.08 years) NDCKD patients were included. There was no significant difference between DNP and NDCKD groups in terms of OH prevalence (70.5 vs. 61.7%, p = 0.181). Male patients had significantly higher OH prevalence than female patients (74.7 vs. 60.0%, p = 0.026). There was no significant difference in change in systolic BP between the groups (24.00 [10.00-32.00] mm Hg vs. 24.00 [13.75-30.25] mm Hg, p = 0.797), but the change in diastolic BP was significantly higher in the DNP group (8.00 [2.00-13.00] mm Hg vs. 6.00 [2.00-9.00] mm Hg, p = 0.025). In the DNP group, patients with OH had significantly higher uric acid levels than those without OH (7.18 ± 1.55 vs. 6.36 ± 1.65 mg/dL, p = 0.017). And, 73.7% of patients on calcium channel blockers developed OH (p = 0.015), and OH developed in 80.6% of 36 patients on alpha-blockers (p = 0.049). CONCLUSION: OH prevalence is very high in CKD, and etiology of CKD does not have a statistically significant effect on the frequency of OH, despite a difference that could be meaningful clinically. Therefore, patients with CKD are checked for OH, with or without concurrent diabetes mellitus. Evaluation of postural BP changes should be a part of nephrology practice.

Others Are to Blame (Displacement in patients with drug-resistant epilepsy).

OBJECTIVE: To evaluate the defense mechanisms (DM) in patients with drug-resistant epilepsy and, to determine whether displacement is associated with seizures. SUBJECTS AND METHODS: Following an examination, 50 patients were diagnosed in accordance with the 2005 proposal of the International League Against Epilepsy and the definition of drug-resistant epilepsy from 2010. The neuropsychological examination used the Defense Style Questionnaire (DSQ-40). We measured the intensity of individual DMs. Mature DMs: sublimation, humor, suppression and anticipation; neurotic DMs: undoing, pseudo-altruism, idealization and reactive formation; and immature DMs: projections, passive aggression, acting out, isolation, devaluation, autistic fantasies, denial, displacement, dissociation, splitting, rationalization and somatization. The values were compared with 50 subjects without epilepsy. RESULTS: Patients with drug-resistant epilepsy use immature defensive styles significantly more (p=0.0010). Displacement have a positive correlation with frequency of seizure (p=0.0412). CONCLUSION: Blaming others is a characteristic of the behavior of patients with drug-resistant epilepsy, especially if they have seizures. As such, they may be less adaptable in a micro social environment.

Risk Factors in Acute Stroke Patients With and Without Sleep Apnea.

BACKGROUND: More than 50% of stroke patients have sleep-disordered breathing (SDB), mostly in the form of obstructive sleep apnea (OSA). SDB represents both a risk factor and a consequence of stroke. The presence of SDB has been linked with the poorer long-term outcome and increased long-term stroke mortality. About 20 to 40% of stroke patients have sleep-wake disorders (SWD), mostly in form of insomnia, excessive daytime sleepiness/fatigue, or hypersomnia (increased sleep needs). OBJECTIVE: The aim of this study was to analyze the frequency of risk factors in patients with acute stroke and sleep apnea. METHODS: The study included patients without cognitive impairment or with mild cognitive impairment. The diagnosis of apnea syndrome was made on the basis of the Snoring and Apnea Syndrome Questionnaire, the Epworth Sleep Scale, the Berlin Questionnaire, the Stanford Sleepiness Scale, and the General Sleep Questionnaire. The severity of stroke was assessed by the National Institutes of Health Stroke Scale and the Rankin Disability Scale. Patients with a Glasgow score <8 on the day of neuropsychiatric examination were excluded from the study, as well as patients with epileptic seizures at the onset of stroke, with aphasia, with Mini - mental test <23, with verified previous dementia / cognitive impairment. RESULTS: There is no statistically significant difference in the age of men and women, both with apnea and without apnea. In patients with apnea, heart disease was in the first place 91.8%, followed by hypertension 86.4%, Body mass index 79.1%, hyperlipidemia 50%, smoking 38.2 % and diabetes mellitus 20.9%. Hypertension was the most common risk factor in patients without apnea 83.6%, followed by heart disease 81.0%, Body mass index 60.9%, hyperlipidemia 48.21%, smoking 28.2 % and diabetes mellitus 20%. CONCLUSION: Heart diseases, hypertension and body mass index are significantly more frequent in patients with than in patients without sleep apnea.

Oleh Hornykiewicz (1926-2020): Sixty Years since the Pioneering L-DOPA Application - One Year since the Death of the Pioneer.

Oleh Hornykiewicz was born on November 17, 1926 in Lamberg, Ukraine. After completing his studies in July 1951, he moved to the "Pharmacological Institute of the University of Vienna". In 1958, he started his research on centrally acting drugs at the same institute and came up with the idea of linking laboratory observations with animals with the basal ganglia of the human brain. Soon, Hornykiewicz initiated a new question: L-DOPA as a therapy for Parkinson's disease? Fortunately, after administration of this new drug, patients were able to perform motor activities which could not be prompted to any comparable degree by any known drug. In the following decades, initial fiction became an unavoidable fact. Dopamine, adapted and combined with carbidopa or benzerazide, has evolved into a drug that no longer recognizes the borders of countries and continents. Distinguished emeritus prof. Oleh Hornykiewicz died on May 26, 2020 at the age of 93 in Vienna, Austria. Unfortunately, despite everything he has done and deserved, the Nobel Prize was not received.

The relationship between measures of foot mobility and subtalar joint stiffness using vibration energy with color Doppler imaging-A clinical proof-of-concept validation study.

INTRODUCTION: Subtalar joint (STJ) dysfunction can contribute to movement disturbances. Vibration energy with color Doppler imaging (VECDI) may be useful for detecting STJ stiffness changes. OBJECTIVES: (1) Support proof-of-concept that VECDI could detect STJ stiffness differences; (2) Establish STJ stiffness range in asymptomatic volunteers; (3) Examine relationships between STJ stiffness and foot mobility; and (4) Assess VECDI precision and reliability for examining STJ stiffness. METHODS: After establishing cadaveric testing model proof-of-concept, STJ stiffness (threshold units, ΔTU), ankle complex passive range-of-motion (PROM) and midfoot-width-difference (MFWDiff) data were collected in 28 asymptomatic subjects in vivo. Three reliability measurements were collected per variable; Rater-1 collected on all subjects and rater-2 on the first ten subjects. Subjects were classified into three STJ stiffness groups. RESULTS: Cadaveric VECDI measurement intra-rater reliability was 0.80. A significantly lower STJ ΔTU (p = .002) and ankle complex PROM (p < .001) was observed during the screw fixation versus normal condition. A fair correlation (r = 0.660) was observed between cadaveric ΔTU and ankle complex PROM. In vivo VECDI measurements demonstrated good intra-rater (0.76-0.84) versus poor inter-rater (-3.11) reliability. Significant positive correlations were found between STJ stiffness and both dorsum (r = .440) and posterior (r = .390) PROM. MFWDiff exhibited poor relationships with stiffness (r = .103) and either dorsum (r = .256) or posterior (r = .301) PROM. STJ stiffness ranged from 2.33 to 7.50 ΔTUs, categorizing subjects' STJ stiffness as increased (n = 6), normal (n = 15), or decreased (n = 7). Significant ANOVA main effects for classification were found based on ΔTU (p< .001), dorsum PROM (p = .017), and posterior PROM (p = .036). Post-hoc tests revealed significant: (1) ΔTU differences between all stiffness groups (p < .001); (2) dorsum PROM differences between the increased versus normal (p = .044) and decreased (p = .017) stiffness groups; and (3) posterior PROM differences between the increased versus decreased stiffness groups (p = .044). A good relationship was found between STJ stiffness and dorsum PROM in the increased stiffness group (r = .853) versus poor, nonsignificant relationships in the normal (r = -.042) or decreased stiffness (r = -.014) groups. CONCLUSION: PROM may not clinically explain all aspects of joint mobility. Joint VECDI stiffness assessment should be considered as a complimentary measurement technique.
