The aim of this systematic review was to synthesise the characteristics of older adults (OA) and to give an account of how and when multicomponent exercise (MCE) has been used to improve physical and psychological health, as well as their cognitive function. This systematic review was conducted on 21 articles published in PsycINFO, Medline, and Web of Science databases from 2009 to 2019, using the procedures set out in the PRISMA statement. The total sample consisted of 3,768 older adults with a mean age of 74.2. More than three-quarters (76%) of the articles studied older adults that lived in the community. evidenced Frailty was observed in the subjects in 23.8% of the articles. In 76% of the studies, a health professional was responsible for the program. Just under half (48%) of the studies were carried out in places equipped for exercise. The most frequent parameters used were two weekly 45 to 60-minute-long sessions for six months. The most frequent variables for physical health, psychological health, and cognitive function were muscle strength, social function, and memory, respectively. To assess physical health, psychological health, and cognitive function, the most frequent tools used were the timed up and go test (TUG), the geriatric depression scale (GDS), and the mini-mental state examination (MMSE), respectively. It was concluded that there is an age and health profile of OA who participate in MCE. The parameters and times most frequently used in MCE, along with the most frequently used parameters and times were recorded. In addition, the variables of interest, and the tools used to evaluate the effects of MCE on physical and psychological health and cognitive functions, were identified.
The Covid-19 pandemic has had a profound impact on the Otolaryngology outpatient clinical practice, which is at high risk of respiratory viral transmission due to the close contact between the examiner and the patient's airway secretions [1]. Moreover, most otolaryngological procedures, including oropharyngoscopy, generate droplets or aerosols from high viral shedding areas [1]. Thus, only non-deferrable consultations were performed in the outbreak's acute phase. Along with the re-opening of elective clinical services and the impending second wave of the outbreak, a reorganization is necessary to minimize the risk of nosocomial transmission [1].

This video (Video 1) shows how to safely conduct an outpatient Otorhinolaryngological consultation, focusing on complete ear, nose and throat examination, according to evidences from the published literature and Otolaryngological societies guidelines [2,3].

After telephonic screening, patients reporting Covid-19 symptoms or closecontact with a Covid-19 case withonal otolaryngological examination [5]. When necessary, nasal topic decongestion and anesthesia must be performed using cottonoids rather than sprays [3]. The patient keeps the nose and mouth covered throughout the consultation, lowering the surgical mask on the mouth for nasal endoscopy and removing it only for oropharyngoscopy. After the consultation, the doffing procedure must be carried out carefully to avoid contamination [4]. All the equipment and surfaces must undergo high-level disinfection with 70% alcohol or 0.1% bleach solutions [3]. Proper room ventilation must precede the next consultation [3].

The hints provided in this video are useful to ensure both patient and examiner safety during Otolaryngological outpatient consultations and to reduce SARS-CoV-2 transmission.

The spiral rotational advancement flap is a single-stage technique that has been described for the closure of nasal ala defects and in nipple reconstruction. Herein we present our experience using the spiral flap for closure of moderately sized defects of the scalp vertex in children. Compared to other scalp reconstructive approaches, such as a simple rotational flap or primary linear closure, the spiral flap design offers improved cosmesis through recreation of the natural whorl pattern within the hair-bearing scalp. Scar camouflage is especially important in the pediatric population, as increased skin elasticity and continued cranial growth impart a high risk of scar widening in children.

The electronic patient database at a single, urban, academic, tertiary pediatric otolaryngology and facial plastic surgery practice was queried to identify children who had undergone scalp reconstruction. The medical records of three children who had undergone spiral rotational advancement flap closure by a single surgoach has the added advantage of simulating the natural hair whorl in a cosmetically sensitive region and may serve as an effective alternative to linear reconstruction methods. The technique described can be added to the armamentarium of the pediatric plastic surgeon.
To calculate the minimal clinically important difference (MCID) of the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity Computer Adaptive Test (UE CAT) and Quick-Disabilities of the Arm, Shoulder, and Hand (QuickDASH) for ligament reconstruction tendon interposition (LRTI) patients.

Adult patients treated with LRTI for trapeziometacarpal OA by fellowship-trained hand surgeons between December 2014 and February 2018 at an academic tertiary institution were included. Outcomes were prospectively collected at each visit by tablet computer, including the QuickDASH, PROMIS UE, Pain Interference, Depression, and Anxiety CATs. Inclusion required a response to the anchor question "How much relief and/or improvement do you feel you have experienced as a result of your treatment?" on a 6-option Likert scale, as well as preoperative (≤120 days before surgery) and follow-up (2-26 weeks) outcomes. We calculated MCID both by an anchor-based approach using the mean score of the minimal change group, and with the 0.5 SD method.

Of 145 included participants, mean age was 63 ± 8 years and 74% were female. NHWD-870 Anchor-based MCID estimates for the total cohort were 4.2 for the PROMIS UE CAT and 8.8 for the QuickDASH. The MCID estimates using the 0.5 SD method were 4.8 and 11.7, respectively.

We propose MCID values of 4.2 to 4.8 for the PROMIS UE CAT and 8.8 to 11.7 for the QuickDASH when powering clinical studies or when assessing improvement among a cohort of patients who have undergone LRTI surgery.

Minimal clinically important difference estimates are helpful when interpreting clinical outcomes after LRTI and for powering prospective trials.

The purpose was to describe the impact of botulinum toxin A (BTX-A) administration in patients with ischemic vasospasm on the magnitude and timing of pain relief and subsequent effect on opioid use. The secondary purposes were to determine the role of photoplethysomgraph (PPG) testing on treatment decisions, effect on patient-reported outcomes, and additional procedures.

A retrospective analysis of patients who received BTX-A injections was performed. Botulinum toxin type A was injected subcutaneously in symptom-specific 2-level patterns. Pain, shortened version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH), and opioid use (quantified by median morphine equivalents) were recorded and the need for repeat injections or unplanned surgeries was assessed.

All patients (n= 20 patients; 31 hands) had ischemic pain from vasospasm and failed multiple pharmacological options. Average follow-up was 10.5 months. All patients had abnormal PPG amplitude (mean, 6.43 mm) at room temperature and increascity to improve after warm water immersion was helpful in consideration of BTX-A use.

To localize the brain structures involved in blepharospasm.

This is a retrospective consecutive series of brain MRI's of patients with secondary blepharospasm whose immediate past medical history included cerebrovascular accident or head trauma.

Six patients, including 4 with CVA with ischemic or hemorrhagic lesions of the thalamus and caudate nuclei and 2 with head trauma with contusive sequellae to the tectal plate and frontal cortical and cerebellar atrophy.

According to the literature, brain lesions associated with blepharospasm involve mainly the thalamus, head of the caudate nucleus, corpus striatum, globus pallidus, internal capsule, cerebral cortex and cerebellum. This study demonstrates that blepharospasm is associated with a lesion of a complex neural network - cortex-thalamus-globus pallidus-cortex - and does not correspond to a single, unique lesion. This network is connected with ascending and descending sensory-motor pathways and motor nuclei.

Patients with hepatitis C virus (HCV) have an increased risk of complications after total joint arthroplasty (TJA). There is a limited but growing body of evidence on the benefit of preoperative antiviral treatment to reduce complications after TJA. What has not been well established is the effect of preoperative antiviral treatment among those with advanced disease as indicated by hepatic fibrosis.

In total, 270 patients at 2 urban medical centers were reviewed for patient demographics, comorbidities, HCV treatment, hepatic fibrosis status, surgical information, and postoperative complications. Patients were divided into 2 groups based on their antiviral treatment status prior to TJA Treated (n= 129) and Untreated (n= 141). Pearson's chi-squared test, Student's t-test, and multivariate logistic regressions were used to analyze complications between groups.

Patients in the Treated group had significantly fewer all-type complications (4.7% vs 14.9%, P= .007), infections (2.3% vs 12.1%, P= .002), and reope presence of hepatic fibrosis.
Femoral component rotation in total knee arthroplasty (TKA) has a significant impact on balance and patellofemoral kinematics. However, normal anatomic relationships between rotational axes are poorly understood. As such, we sought to characterize anatomic femoral rotational axes in patients undergoing primary TKA.

We identified 100 patients who underwent a primary TKA with a preoperative computed tomography scan. The angles between the surgical epicondylar axis (SEA) and the anterior-posterior (AP) axis to the posterior condylar axis (PCA) were measured independently by a musculoskeletal fellowship-trained radiologist and a fellowship-trained arthroplasty surgeon. We simulated an ideal TKA in which the femoral component was placed exactly 3° external to the PCA and measured resulting rotation.

The SEA was on average 1.5° externally rotated to the PCA (range 3.1° internal to 7.0° external). The AP axis was on average 4.5° externally rotated to the PCA (range 2.3° internal to 10.3° external). The AP axis was a mean 2.
