The contribution of medical burden to 22q11.2 deletion syndrome quality of life and functioning.

PURPOSE: To date, there is no systematic method to quantify the medical burden of individuals with 22q11.2 deletion syndrome (22q11.2DS). This study aimed to design a Medical Burden Scale for 22q11.2DS to evaluate the effect of medical symptoms severity on quality of life (QoL) and functioning in individuals with this syndrome. METHODS: Individuals with 22q11.2DS (n = 76) were included in the study. A multidisciplinary group of physicians determined the severity of symptoms (on a scale of 0 to 4) of 8 major medical systems affected in 22q11.2DS, as well as the level of cognitive deficits and psychiatric morbidity. Regression models were used to evaluate the impact of medical, cognitive, and psychiatric symptoms' severity on global assessment of functioning (GAF) and QoL. RESULTS: The total Medical Burden Scale score was significantly associated with both QoL and GAF scores, beyond the effect of the psychiatric and cognitive deficits. We also found that QoL and GAF scores were associated with the severity scores of specific medical systems, particularly neurological symptoms, but also cardiovascular, ear-nose-throat, endocrinology, and orthopedics. CONCLUSION: Quantifying the medical burden of 22q11.2DS individuals is feasible and indicates the overall and specific contribution of medical symptoms to QoL and functioning of 22q11.2DS individuals.

COVID-19 vaccination in patients with multiple sclerosis: What we have learnt by February 2021.

BACKGROUND: Since vaccination against coronavirus disease 2019 (COVID-19) became available, risks related to vaccinating patients with multiple sclerosis (MS) need to be carefully assessed. OBJECTIVE: Characterize safety and occurrence of immediate relapses following COVID-19 vaccination in a large cohort of MS patients. METHODS: We assessed the safety of BNT162b2 COVID-19 vaccination in adult MS patients. RESULTS: Between 20 December 2020 and 25 January 2021, 555 MS patients received the first dose of BNT162b2 vaccine and 435 received the second dose. There were three cases of COVID-19 infection encountered after the first dose. Safety profile of COVID-19 vaccine was characterized by pain at the injection site, fatigue, and headache. No increased risk of relapse activity was noted over a median follow-up of 20 and 38 days after first and second vaccine doses, respectively. The rate of patients with acute relapse was 2.1% and 1.6% following the first and second doses, respectively, similar to the rate in non-vaccinating patients during the corresponding period. Mild increase in the rate of adverse events was noted in younger patients (18-55 years), among patients with lower disability (Expanded Disability Status Scale (EDSS) ⩽3.0), and in patients treated with immunomodulatory drugs. CONCLUSION: COVID-19 BNT162b2 vaccine proved safe for MS patients. No increased risk of relapse activity was noted.

Physical activity participation according to the pyramidal, sensory, and cerebellar functional systems in multiple sclerosis.

The objective of the study was to examine the differences in physical activity participation with the pyramidal, cerebellar, and sensory functional systems in people with multiple sclerosis (PwMS). This cross-sectional study included 289 PwMS with a median EDSS of 2.0 (range 0-6.5) and a mean disease duration of 6.8 (SD = 8.4) years. The Godin leisure-time exercise questionnaire (GLTEQ) assessed physical activity participation. The sample was divided into seven groups according to the pyramidal, cerebellar, and sensory functional system scores derived from the EDSS data. Additionally, PwMS were divided into three physical activity subgroups (active, moderately active, and insufficiently active). Furthermore, PwMS were categorized into four levels of disability based on their global Expanded Disability Status Scale (EDSS) score [very mild (0-1.5), mild (2.0-3.5), moderate (4.0-5.5), and severe (6.0-6.5)]. In the physical activity subgroups, 159 (55.0%) were classified as insufficiently active, 59 (20.4%) as moderately active, and 71 (24.6%) as active. Pyramidal, cerebellar, and sensory impairments were demonstrated in 134 (46.4%), 73 (25.3%), and 85 (29.4%) patients, respectively. No differences were found for the GLTEQ scores for all seven functional system groups (P value = 0.168). As for the EDSS disability subgroups, the percentage of active patients (moderately at least) were 60%, 45.8%, 36.5%, and 15.4%, for the very mild, mild, moderate, and severe subgroups, respectively. This study found that participation in leisure-time physical activity is independent from the pyramidal, cerebellar, and sensory functional systems in PwMS.

The relationship between gait variability and cognitive functions differs between fallers and non-fallers in MS.

The objective of the study was to determine if cognitive function is associated with step time variability in people with multiple sclerosis (PwMS). The study included 355 PwMS (218 women), average age 41.1 (SD = 13.5), disease duration 5.9 (SD = 7.3) years, and a median expanded disability status scale score of 2.5. We separately analyzed the sample group of fallers and non-fallers based on their fall history. Gait variability was measured by an electronic walkway and all participants completed a computerized cognitive test battery designed to evaluate multiple cognitive domains. Fallers (43.7%) demonstrated elevated step time variability (%CV), 5.0 (SD = 3.4) vs. 3.5 (SD = 1.6), P < 0.001 compared to the non-faller subjects. According to the regression analysis in the non-fallers' group, step time variability was found significantly associated with the global cognitive score (P = 0.001), executive function subcategory (P = 0.038), and motor skills subcategory (P < 0.001). No relationship between step time variability and any cognitive domain was demonstrated in the faller group. This study illustrated that the association between gait variability and cognition occurs only in PwMS without a fall history. From a clinical standpoint, these findings might help medical professionals to create improved assessment tests and rehabilitation strategies in the MS population.

Management of the spastic hip in cerebral palsy.

PURPOSE OF REVIEW: Spastic hip dysplasia (SHD) is a common finding in patients with cerebral palsy, with a higher incidence in more involved patients, causing disability and reducing quality of life in these patients. SHD is the most serious orthopedic problem seen in cerebral palsy patients, and requires special attention and tenacious evaluation of the patients. The aim of this article is to review the new developments in the treatment of SHD. RECENT FINDINGS: Patients with cerebral palsy were shown to have better hip joint morphology when they had access to hip surveillance programmes, with proactive search of patients with progressing hip subluxation and early intervention. Prediction of progression of SHD is now available based on the experience of these programmes.Patients who underwent hip joint reconstruction showed that incongruent joints remodeled following a Dega osteotomy. Patients who underwent a varus osteotomy of the femoral neck without pelvic reconstruction had a higher rate of recurrence when they were older and the SHD was more severe. Health-related quality of life measures improved following hip joint reconstructions and salvage procedures. CONCLUSION: Patients with cerebral palsy should be monitored with a well-defined hip surveillance programme, with early identification and timely intervention for SHD.

Construct Validity of the Four Square Step Test in Multiple Sclerosis.

OBJECTIVE: To expand the construct validity of the Four Square Step Test (FSST) in people with multiple sclerosis (PWMS). DESIGN: Cross-sectional study. SETTING: Multiple sclerosis center. PARTICIPANTS: PWMS (N=218; 133 women, 85 men; mean age, 43.2±13.5y; mean disease duration, 7.5±7.7y since diagnosis) were enrolled in the study. The Expanded Disability Status Scale score was 3.1±1.3, indicating minimal to moderate neurologic disability. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The FSST, posturography measures, 2-minute walk test, timed Up & Go test, timed 25-foot walk, fall status, Falls Efficacy Scale International, Modified Fatigue Impact Scale, instrumented cognitive assessment, and 12-item Multiple Sclerosis Walking Scale. RESULTS: The FSST score of the total sample was 11.0±4.9. Significant differences were observed between the very mild, mild, and moderate disability groups: 8.8±3.4, 11.1±4.9, and 14.1±5.3, respectively. In terms of fall status, the fallers demonstrated a significant slower FSST score than the nonfallers (12.5±5.7 vs 9.0±2.6, respectively). Modest significant correlation scores were found between the FSST and the timed Up & Go test and 2-minute walk test (Pearson ρ=.652 and ρ=-.575, respectively). In terms of posturography, all measures were significantly associated with the FSST scores. A significant positive relation was observed with the visual spatial cognitive domain (Pearson ρ=-.207). CONCLUSIONS: The current study supports and broadens the construct validity of the FSST in PWMS.

Effect of Alfacalcidol on multiple sclerosis-related fatigue: A randomized, double-blind placebo-controlled study.

CONTEXT: Fatigue is one of the most common and disabling symptoms of multiple sclerosis (MS); however, there is no medication that has been approved specifically to treat MS-related fatigue. OBJECTIVE: We aimed to evaluate the effect of vitamin D analogue, Alfacalcidol, on MS-related fatigue. DESIGN, SETTINGS, PARTICIPANTS: This was a randomized, double-blind, parallel group, placebo-controlled trial in patients with clinically definite MS by McDonald criteria conducted in a single university-affiliated medical center in Israel. Randomly selected patients from the Sheba MS Registry computerized database (N=600) were assessed using the self-report Fatigue Severity Scale (FSS). Patients with clinically meaningful fatigue (N=259) were further assessed for trial eligibility, and MS patients with significant fatigue (N=158; 61%, 118 females, mean age 41.1 ± 9.2 years and mean disease duration of 6.2 ± 5.5 years) were included in the study and randomized to receive treatment or placebo. INTERVENTION: Alfacalcidol (1 mcg/d, N=80) or placebo (N=78) was administered for six consecutive months. MAIN OUTCOME MEASURE: The primary endpoint of the study was the change between Alfacalcidol and placebo-treated patients in the Fatigue Impact Scale (FIS) score; the cut-off point for improvement was defined as 30% decrease. All analyses followed the intention-to-treat principle and were performed for all participants based on the group they were randomly allocated regardless of whether or not they dropped out. RESULTS: Alfacalcidol decreased the mean relative FIS score as compared with placebo (-41.6% vs. -27.4%, p=0.007, respectively). This advantage was further emphasized when the modified FIS (MFIS) relative change was calculated. Quality of Life (QoL) improved in Alfacalcidol-treated patients as compared with placebo in the RAYS psychological (p=0.033) and social (p=0.043) sub-scales. The Alfacalcidol-treated group had reduced number of relapses (p=0.006) and higher proportion of relapse-free patients (p=0.007). Reduction of relapses by Alfacalcidol became significant at 4 months of treatment, was sustained at 6 months and decayed 2 months after drug discontinuation. Alfacalcidol treatment was safe and no serious adverse events were recorded. CONCLUSION: Alfacalcidol is a safe and effective treatment strategy to decrease fatigue and improve QoL in patients with MS.

A personalized, intense physical rehabilitation program improves walking in people with multiple sclerosis presenting with different levels of disability: a retrospective cohort.

BACKGROUND: People with multiple sclerosis (PwMS) endure walking limitations. To address this restriction, various physical rehabilitation programs have been implemented with no consensus regarding their efficacy. Our objective was to report on the efficacy of an integrated tailored physical rehabilitation program on walking in people with multiple sclerosis categorized according to their level of neurological disability. METHODS: Retrospective data were examined and analyzed. Specifically, data obtained from all patients who participated in the Multiple Sclerosis Center's 3 week rehabilitation program were extracted for in depth exploration. The personalized rehabilitation program included three major components modified according to the patient's specific impairments and functional needs: (a) goal directed physical therapy (b) moderately intense aerobic exercise training on a bicycle ergometer and (c) aquatic therapy chiefly oriented to body structures appropriate to movement. Gait outcome measurements included the 10 meter, 20 meter, Timed up and go and 2 minute walking tests measured pre and post the rehabilitation program. Three hundred and twelve people with relapsing-remitting multiple sclerosis were included in the final analysis. Patients were categorized into mild (n = 87), moderate (n = 104) and severely (n = 121) disabled groups. RESULTS: All clinical walking outcome measurements demonstrated statistically significant improvements, however, only an increase in the 2 minute walking test was above the minimal clinical difference value. The moderate and severe groups considerably improved compared to the mild gait disability group. Mean change scores (%) of the pre-post intervention period of the 2 minute walking test were 19.0 (S.E. = 3.4) in the moderate group, 16.2 (S.E. = 5.4) in the severe group and 10.9 (S.E. = 2.3) in the mild gait disability group. CONCLUSIONS: We presented comprehensive evidence verifying the effects of an intense goal-directed physical rehabilitation program on ambulation in people with multiple sclerosis presenting with different neurological impairment levels.

The value of hip aspiration in pediatric transient synovitis.

INTRODUCTION: Hip transient synovitis (TS) is a common pediatric orthopaedic problem. Although a self-limiting illness, it often makes the patient temporarily disabled and poses a diagnostic difficulty because of its similarity to septic arthritis in clinical manifestations. The aim of this study was to evaluate the use of a single ultrasound-guided hip aspiration as a treatment modality for TS. METHODS: Between the years 1984 and 1989, 112 children with TS were treated through bed rest and using nonsteroidal anti-inflammatory drugs (group 1). Between the years 1990 and 1999, 119 children diagnosed with TS were treated using hip aspiration, bed rest, and nonsteroidal anti-inflammatory drugs (group 2). Recovery parameters were compared between these patient groups. RESULTS: Twenty-four hours after admission, limping was noted in 92% and 10% of the patients in groups 1 and 2, respectively, (P < 0.001). Refusal to bear weight was observed in 14% and 1% in groups 1 and 2, respectively, (P < 0.001), and hip joint pain was reported in 81% and 6% in groups 1 and 2, respectively, (P < 0.001). Larger joint effusions were found to be the reason behind the inability to bear weight. CONCLUSIONS: Pain due to TS may be because of capsule stretching owing to the accumulation of joint effusion. Ultrasound-guided hip aspiration relieves pain and limitation in movement and provides rapid differential diagnosis from septic arthritis of the hip joint.

Scoliosis in RETT Syndrome: A National Referral Centre Experience.

STUDY DESIGN: This was a retrospective case series. OBJECTIVE: The objective of this study was to discuss the treatment challenges in scoliosis patients with Rett syndrome (RTT) in a national referral centre for RTT. We describe structural characteristics of curves, age of onset, genetic mutation, ambulation status, and treatment through RTT progression. Based on this unique experience, we aimed to suggest guidelines for scoliosis treatment in RTT patients. SUMMARY OF BACKGROUND DATA: RTT is a neurodevelopmental disorder associated with a mutation in the methyl-CpG binding protein 2 (MECP2) gene, primarily in females with significant features of growth failure, gastrointestinal and pulmonary dysfunction, ataxia, seizures, and intellectual disability. Scoliosis is the most common orthopedic manifestation of RTT and is present in 64%-75% of patients. No clear guidelines for scoliosis treatment in RTT are available, and typically patients are treated according to guidelines of another neuromuscular scoliosis. METHODS: Clinical and radiographic data were gathered, including MECP2 mutation type, scoliosis characteristics, preoperative treatment, surgical treatment, functional status, and postoperative follow-up. RESULTS: Our cohort included 102 patients with RTT. They were 36 who presented with scoliosis; 18 were treated surgically. C-curve was found in 17 patients and S-type in 19. Scoliosis treatment onset was 8.76 years in the C-type group and 13.88 years in the S-type group. The average curve at the time of surgery was 52.42 degrees. The average time until surgery was 2.44 years. Seventeen patients underwent posterior spinal fusion, and 1 patient underwent posterior spinal fusion+anterior spinal fusion with an average correction of 40 degrees. The most common mutation was R255X nucleotide (30% of cases). The most severe curves had mutations R168X and R270X nucleotides. CONCLUSIONS: We advise early monitoring for patients with RTT and scoliosis due to early and rapid progression. Common mutations found were R255X, R168X, R270X, and T158M. We recommend surgical treatment in every curve above 45 degrees, independently of age.

The month of birth and the incidence of multiple sclerosis in the Israeli population.

BACKGROUND: Recent studies on date of birth of multiple sclerosis (MS) patients showed a spring peak and an autumn nadir. We examined the effect of date of birth in a large group of MS patients and non-MS patients, compared to the general population in Israel. METHODS: A retrospective analysis was performed in a large cohort of MS patients and patients with other neurological disorders. The date of birth, gender, and country of birth were identified for each patient. The results were compared to a national database. RESULTS: There were 2,264 MS patients and 1,758 patients with other diagnoses. No significant peak or nadir in the date of birth was identified in either group, both in patients born in Israel or in immigrants. No difference was found compared to the national birth rate. When we controlled for the country of birth, there was no difference. CONCLUSION: An increased frequency of MS patients born in the months of April and May was considered as a proof of maternal influence. The results of our study show that this finding is not consistent worldwide. The month of birth was not found to be a significant factor in Israeli MS patients.

Reducing musculoskeletal disorders among computer operators: comparison between ergonomics interventions at the workplace.

Typing is associated with musculoskeletal disorders (MSDs) caused by multiple risk factors. This control study aimed to evaluate the efficacy of a workplace intervention for reducing MSDs among computer workers. Sixty-six subjects with and without MSD were assigned consecutively to one of three groups: ergonomics intervention (work site and body posture adjustments, muscle activity training and exercises) accompanied with biofeedback training, the same ergonomics intervention without biofeedback and a control group. Evaluation of MSDs, body posture, psychosocial status, upper extremity (UE) kinematics and muscle surface electromyography were carried out before and after the intervention in the workplace and the motion lab. Our main hypothesis that significant differences in the reduction of MSDs will exist between subjects in the study groups and controls was confirmed (χ(2) = 13.3; p = 0.001). Significant changes were found in UE kinematics and posture as well. Both ergonomics interventions effectively reduced MSD and improved body posture. PRACTITIONER SUMMARY: This study aimed to test the efficacy of an individual workplace intervention programme among computer workers by evaluating musculoskeletal disorders (MSDs), body posture, upper extremity kinematics, muscle activity and psychosocial factors were tested. The proposed ergonomics interventions effectively reduced MSDs and improved body posture.

Treatment of Septic Arthritis of the Hip Joint Using Repeated Aspirations: When Should We Operate?

Background: The well-accepted treatment of septic arthritis of the hip joint (SAHJ) is surgical drainage of the joint, but repeated aspirations of the hip joint under sonography, have been used for over twenty years with significant success in some centers, including ours. In recent years, we identified some children who did not respond to aspirations and had to undergo arthrotomies. We were concerned that some children may have reached the operating room after a longer than ideal time. Objective: Identification of the characteristics of patients who did not respond to repeated aspirations and development of a treatment algorithm that expedites decision-making regarding the necessity of surgery. Methods: This is a single-center retrospective cohort analysis. All the patients diagnosed with SAHJ between 2007 and 2019 were identified. Patients who responded to repeated aspirations were compared to those who did not improve and required surgery. Demographic and clinical data and laboratory results were obtained from the patients' electronic medical records. Results: Forty-eight children (88.9%) were treated successfully with repeated aspirations and six children (11.1%) did not improve after aspirations and underwent hip arthrotomies. Five out of 48 children from the aspiration group (10.4%) and 4 out of 6 from the arthrotomy group (66.7%) had chronic comorbidities (p = 0.0051). The mean duration of fever over 38.5 degrees centigrade and the length of stay were higher in the arthrotomy group (p = 0.0040, p = 0.0301, respectively). When we examined the change in C-reactive protein (CRP) levels before and after the first aspiration (Delta CRP), we found a decrease in the aspiration group and an increase in the arthrotomy group (p = 0.0044). Conclusion: The new algorithm which we present allows an expeditious assessment of the patient's response to the repeated aspiration method and thus prevents unnecessary surgeries for the treatment of SAHJ. Patients with chronic comorbidities, prolonged fever, and an increase in CRP level following the first aspiration, are at risk of treatment failure and should be treated with an arthrotomy. Level of evidence for clinical articles: Level 4-cohort study.

Longitudinal relationships between disability and gait characteristics in people with MS.

Longitudinal data are vital in order to understand intra individual gait changes with the progression of multiple sclerosis (MS). Therefore, the primary aim of this study was to explore the relationship between changes in disability with changes in major spatio-temporal parameters of gait in people with MS (PwMS). PwMS (n = 83) completed two gait assessments performed at separate time points (M1, M2). For each individual, the absolute difference between the Expanded Disability Status Scale (EDSS) score, key spatio-temporal parameters of gait, Falls Efficacy Scale International (FES-I), and the 12-item Multiple Sclerosis Walking Scale (MSWS-12), were calculated. The mean time difference between M1 and M2 was 2.5 (SD = 1.7) years. At M2, PwMS presented with shorter strides, a wider base of support, increased perceived mobility difficulties and fear of falling compared with M1. According to the odds ratio (OR) analysis, the odds of experiencing an increase in the EDSS score was significantly higher once the MSWS-12 score increased at M2 compared with M1 (OR = 7.930, p = 0.004). This observation was highlighted specifically in people with mild-moderate MS (OR = 12.427, p < 0.001). The increase in the EDSS score was not associated with changes in key spatio-temporal parameters of gait. The present study provides a better understanding of gait and disease progression in PwMS, highlighting the significant role of the MSWS-12.

Motoric cognitive risk syndrome in people with multiple sclerosis: prevalence and correlations with disease-related factors.

Background: The motoric cognitive risk (MCR) syndrome, defined as the coexistence of slow gait and subjective cognitive complaints, has as yet not been researched in people with multiple sclerosis (pwMS). Objective: To examine the prevalence of the MCR syndrome in pwMS and its association with disability, disease duration, perceived fatigue, and fear of falling. Methods: The study comprised 618 pwMS [43.7 (SD = 12.6) years, 61.7% females]. Gait speed was measured by the GAITRite™ electronic walkway (CIR Systems, Inc. Haverton, PA, USA). Cognitive status was defined according to the global cognitive score computed by the NeuroTrax™ cognitive battery (NeuroTrax Corporation, Medina, NY, USA). The sample was divided into four main groups: 'normal', 'cognitively impaired', 'gait impaired' or 'MCR'. Perceived fatigue was assessed by the Modified Fatigue Impact Scale; fear of falling by the Falls Efficacy Scale International. Results: Sixty-three (10.2%) patients were diagnosed with MCR. The percentage of subjects categorized as MCR was 26.0% in severely disabled pwMS compared with 10.9%, 6.0%, and 4.6% in moderately, mildly and very mildly disabled pwMS, respectively. Subjects in the MCR group presented with elevated fatigue compared with patients classified as normal [49.7 (SD = 23.3) vs 26.5 (SD = 19.2), p < 0.001]. Fear of falling was significantly higher in the MCR and gait impairment groups compared with the cognitively impaired and normal groups. Conclusions: The current study corroborates the presence of MCR in pwMS. Nevertheless, future longitudinal research is warranted to better understand its application.

Prone vs Supine Positioning for Femoral Derotation Osteotomy: Kinematic and Physical Examination Outcomes Suggest Both Can Achieve Desired Results.

Background: Femoral derotation osteotomy (FDO) for correction of internal rotation gait resulting from cerebral palsy (CP) can be performed with the patient in the prone or supine position. It is not known whether patient positioning during FDO affects the change in hip rotation. Purpose/Questions: We sought to compare the change in hip rotation following FDO performed on patients with CP in the prone or supine position through kinematic analysis. Methods: We conducted a consecutive retrospective cohort study of children with CP, ages 3 to 18 years and with Gross Motor Function Classification System (GMFCS) levels I to III, who underwent prone or supine FDO and pre- and postoperative motion analysis. The prone group included 37 patients (68 limbs) between 1990 and 1995. The supine group included 26 patients (47 limbs) between 2005 and 2015. The groups were matched for gender, age, and GMFCS level. The primary outcome was hip rotation in degrees during stance phase. Secondary outcomes included temporal-spatial parameters, hip abduction, hip and knee extension, and hip and knee passive range of motion (ROM). Results: The prone group had more bilateral patients (100%) than the supine group (81%). The supine group underwent more concomitant procedures. There was no difference between the prone and supine groups in postoperative stance hip rotation; both groups had significantly improved stance hip rotation, step width, and hip rotation passive ROM, pre- to postoperatively. Prone patients had improved postoperative hip extension, pelvic tilt, velocity, and cadence. Conclusions: There was no significant different in stance hip rotation between supine and prone FDO groups. Advocates of prone positioning for FDO suggest it allows more accurate assessment of rotation. Supine positioning may be more convenient when additional procedures are required. Based on our findings, either approach can achieve the desired result.

COVID-19 vaccination in patients with multiple sclerosis: Safety and humoral efficacy of the third booster dose.

BACKGROUND: As immunity against SARS-COV-2 wanes following first and second doses of vaccination, a third dose is administered in several countries around the world. Similarly to the first doses, risks related to vaccination and humoral immune response in patients with multiple sclerosis (MS) need to be assessed. OBJECTIVE: Characterize safety and humoral immune response following the third dose of COVID-19 vaccination in a large cohort of MS patients. METHODS: We assessed the safety of the third dose of the BNT162b2-COVID-19 mRNA vaccination in adult MS patients and evaluated SARS-CoV-2 IgG response. RESULTS: Two hundred and eleven adult MS patients received a third dose of BNT162b2 COVID-19 vaccination. Median follow up time was 66 days from vaccine administration (IQR 54-84). The frequency of any adverse event was 54.5%, with the most common reported adverse events being fatigue, local pain at the injection site, fever and muscle or joint pain. Transient increase in MS symptoms was reported in 3.8% of patients, none of them requiring treatment. The rate of acute relapses treated with IV steroids was 3.3%. In a sub-group of 55 patients, 20 untreated and 35 treated with vaccination-safe disease-modifying treatments, SARS-CoV-2 IgG levels increased 21-fold (median ± SD 21.6 ± 53.05). CONCLUSIONS: The third dose of COVID-19-BNT162b2 vaccine proved safe for MS patients, with no increased risk of relapse activity. Untreated patients and patients treated with vaccination-safe disease-modifying treatments show significant increase in SARS-CoV-2 IgG levels following the third dose of vaccination.

Fractures of the humerus in the neonatal period.

BACKGROUND: Fractures of the humerus in neonates can pose a diagnostic challenge, especially when the fracture occurs in the proximal or distal epiphysis. OBJECTIVES: To review our experience in the diagnosis and treatment of birth-related humeral fractures. METHODS: Between the years 2001 and 2009, seven newborn patients and two patients treated in the neonatal intensive care unit sustained a fracture of the humerus. Four of the fractures occurred in the humeral shaft, three in the proximal epiphysis and two in the distal epiphysis. In all the newborn patients the diagnosis was made on the first day of life using radiography and ultrasonography. The fractures of the shaft and of the distal epiphysis were treated by gentle manipulation and casting, and the fractures of the proximal epiphysis were treated by swaddling. RESULTS: All of the patients demonstrated fracture union within 2 weeks, and radiographs at the age of 6 months demonstrated complete remodeling of the fracture. CONCLUSIONS: Ultrasonography is a simple, readily available and inexpensive modality for the diagnosis of birth-related fractures of the humerus, especially in the yet unossified epiphyses.

[Middle third clavicle fractures--diagnosis, complications and treatment].

Clavicle fractures compose 2.5% to 5% of all fractures, and usually occur due to a direct blow to the shoulder. The incidence of these fractures persistently increases. Most of the fractures are in the middle third--a result of the unique structure of the clavicle and its ligamentous and muscular attachments. The fracture diagnosis includes focused physical examination, radiographic evaluation, and comprehensive evaluation of the patient, considering the fact that the fracture can be the result of significant energy absorption and can hide other injuries. Usually treatment is non-operative, and results in fracture union of 95%. Healing is achieved with a certain amount of deformity. The most common treatment is a sling or figure-of-8 dressing worn for several weeks. When absolute surgical indications (open fracture or neurovascular injury) or relative surgical indications (multiple injuries or floating shoulder) exist, several surgical procedures can be chosen. The fracture displacement as a predictive factor for union or function after healing is controversial. Complications associated with clavicle fractures are the result of either conservative or surgical treatment. The most common complication is an esthetic defect. Other complications are non-union, mal-union, limited range of motion and neurovascular injury.
