Skull Base Primary Extracranial Meningioma with Hyperostosis in a Small Mixed-Breed Dog.

A 7 yr old female spayed Chihuahua-terrier mix was presented for a progressive dry, hacking cough over 9 mo, with dyspnea aggravated by eating and drinking. Computed tomography of the skull revealed a large mineral attenuating mass associated with the left skull base, without intracranial involvement. A modified ventral paramedian hypophysectomy approach along the medial aspect of the left ramus was used to approach the base of the skull. Ninety percent of the mass was debulked via high-speed pneumatic burr. Histopathology was consistent with hyperostosis originating from a primary extracranial meningioma (ECM), with the tissue staining positive for vimentin and negative for cytokeratin. The patient was symptom free for 9 mo before clinical signs returned because of tumor recurrence and was euthanized 11 mo postoperation because of diminished quality of life. ECM is uncommonly reported in the dog, and to the authors' knowledge has not previously been reported with hyperostosis or located along the skull base at the level of the tympanic bulla. Additionally, although hyperostosis predominantly occurs as diffuse bone thickening adjacent to a meningioma, proliferative focal hyperostosis is uncommon. Given the findings in this patient, ECM should be considered as a differential diagnosis for osseous skull base masses.

Myofascial low back pain treatment.

Myofascial pain is a common musculoskeletal problem, with the low back being one of the commonest affected regions. Several treatments have been used for myofascial low back pain through physical therapies, pharmacologic agents, injections, and other such therapies. This review will provide an update based on recently published literature in the field of myofascial low back pain along with a brief description of a sequenced, multidisciplinary treatment protocol called Skilled Hands-on Approach for the Release of myofascia, Articular, Neural and Soft tissue mobilization (SHARANS) protocol. A comprehensive multidisciplinary approach is recommended for the successful management of individuals with myofascial low back pain.

Effectiveness of sustained stretching of the inferior capsule in the management of a frozen shoulder.

BACKGROUND: Physiotherapy treatment of frozen shoulder is varied, but most lack specific focus on the underlying disorder, which is the adhered shoulder capsule. Although positive effects were found after physiotherapy, the recurrence and prolonged disability of a frozen shoulder are major factors to focus on to provide the appropriate treatment. QUESTIONS/PURPOSES: We wished to study the effectiveness of a shoulder countertraction apparatus on ROM, pain, and function in patients with a frozen shoulder and compare their results with those of control subjects who received conventional physiotherapy. METHODS: A total of 100 participants were randomly assigned to an experimental group and a control group, with each group having 50 participants. The control group received physiotherapy and the experimental group received countertraction and physiotherapy. The total treatment time was 20 minutes a day for 5 days per week for 2 weeks. The outcome measures used were goniometer measurements, VAS, and the Oxford Shoulder Score. RESULTS: Improvements were seen in the scores for shoulder flexion (94.1° ± 19.79° at baseline increased to 161.9° ± 13.05° after intervention), abduction ROM (90.4° ± 21.18° at baseline increased to 154.8° ± 13.21° after intervention), and pain (8.00 ± 0.78 at baseline decreased to 3.48 ± 0.71 after intervention) in the experimental group. Sixty percent of the participants (n = 30) were improved to the fourth stage of satisfactory joint function according to the Oxford Shoulder Score in the experimental group compared with 18% (n = 9) in the control group (p < 0.001). CONCLUSIONS: Incorporating shoulder countertraction along with physiotherapy improves shoulder function compared with physiotherapy alone for the treatment of a frozen shoulder. Additional studies are needed focusing on this concept to increase the generalizability of the counter-traction apparatus in various groups. LEVEL OF EVIDENCE: Level II, prospective comparative study. See the Instructions for Authors for a complete description of levels of evidence.

The Nigerian Military Public Health Response to COVID-19: A 14-Month Appraisal.

The COVID-19 pandemic has caused significant morbidity and mortality since its emergence in December 2019. In Nigeria, the government inaugurated the Presidential Task Force on COVID-19 to coordinate resources while the Nigeria Centre for Disease Control led the public health response. The Nigeria Ministry of Defence Health Implementation Programme (MODHIP), in partnership with the US Army Medical Research Directorate - Africa/Nigeria, responded immediately to the pandemic by establishing a public health emergency operations center to coordinate the military response in support of national efforts. MODHIP has 5 functional units and 6 pillars that coordinate testing, surveillance, case management, risk communication, logistics, research, and infection prevention and control. It developed an incident action plan and each pillar had its own terms of reference to guide specific response activities while preventing duplication of efforts within the military and the Nigeria Centre for Disease Control. In addition, awareness and sensitization sessions were conducted on preventive practices for COVID-19 and infrastructure was provided for hand hygiene and screening at all military facilities. Military laboratories were configured for SARS-CoV-2 testing while selected military health facilities were equipped and designated as COVID-19 treatment centers. Research proposals aimed at better understanding the disease and controlling it were also developed. The traditional combat role of the military was redirected to complement this public health emergency response. In this article, we highlight gaps, opportunities, and lessons to improve military participation in public health emergency response in the future. More funding and multisectoral collaboration with civilian institutions are key to strengthening military public health emergency preparedness and response capabilities.

Comparison of Hepatic Arterial Infusion Pump Chemotherapy vs Resection for Patients With Multifocal Intrahepatic Cholangiocarcinoma.

Importance: Intrahepatic cholangiocarcinoma (iCCA) is often multifocal (ie, satellites or intrahepatic metastases) at presentation. Objective: To compare the overall survival (OS) of patients with multifocal iCCA after hepatic arterial infusion pump (HAIP) floxuridine chemotherapy vs resection. Design, Setting, and Participants: In this cohort study, patients with histologically confirmed, multifocal iCCA were eligible. The HAIP group consisted of consecutive patients from a single center who underwent HAIP floxuridine chemotherapy for unresectable multifocal iCCA between January 1, 2001, and December 31, 2018. The resection group consisted of consecutive patients from 12 centers who underwent a curative-intent resection for multifocal iCCA between January 1, 1990, and December 31, 2017. Resectable metastatic disease to regional lymph nodes and previous systemic therapy were permitted. Patients with distant metastatic disease (ie, stage IV), those who underwent resection before starting HAIP floxuridine chemotherapy, and those who received a liver transplant were excluded. Data were analyzed on September 1, 2021. Main Outcomes and Measures: Overall survival in the 2 treatment groups was compared using the Kaplan-Meier method and log-rank test. Results: A total of 319 patients with multifocal iCCA were included: 141 in the HAIP group (median [IQR] age, 62 [53-70] years; 79 [56.0%] women) and 178 in the resection group (median [IQR] age, 60 [50-69] years; 91 [51.1%] men). The HAIP group was characterized by a higher percentage of bilobar disease (88.0% [n = 124] vs 34.3% [n = 61]), larger tumors (median, 8.4 cm vs 7.0 cm), and a higher proportion of patients with 4 or more lesions (66.7% [94] vs 24.2% [43]). Postoperative mortality after 30 days was 0.8% (95% CI, 0.0%-2.1%) in the HAIP group vs 6.2% (95% CI, 2.3%-9.7%) in the resection group (P = .01). The median OS for HAIP was 20.3 months vs 18.9 months for resection (P = .32). Five-year OS in patients with 2 or 3 lesions was 23.7% (95% CI, 12.3%-45.7%) in the HAIP group vs 25.7% (95% CI, 17.9%-37.0%) in the resection group. Five-year OS in patients with 4 or more lesions was 5.0% (95% CI, 1.7%-14.3%) in the HAIP group vs 6.8% (95% CI, 1.8%-25.3%) in the resection group. After adjustment for tumor diameter, number of tumors, and lymph node metastases, the hazard ratio of HAIP vs resection was 0.75 (95% CI, 0.55-1.03; P = .07). Conclusions and Relevance: This cohort study found that patients with multifocal iCCA had similar OS after HAIP floxuridine chemotherapy vs resection. Resection of multifocal intrahepatic cholangiocarcinoma needs to be considered carefully given the complication rate of major liver resection; HAIP floxuridine chemotherapy may be an effective alternative option.

Classification of osteoporosis by artificial neural network based on monarch butterfly optimisation algorithm.

Osteoporosis is a life threatening disease which commonly affects women mostly after their menopause. It primarily causes mild bone fractures, which on advanced stage leads to the death of an individual. The diagnosis of osteoporosis is done based on bone mineral density (BMD) values obtained through various clinical methods experimented from various skeletal regions. The main objective of the authors' work is to develop a hybrid classifier model that discriminates the osteoporotic patient from healthy person, based on BMD values. In this Letter, the authors propose the monarch butterfly optimisation-based artificial neural network classifier which helps in earlier diagnosis and prevention of osteoporosis. The experiments were conducted using 10-fold cross-validation method for two datasets lumbar spine and femoral neck. The results were compared with other similar hybrid approaches. The proposed method resulted with the accuracy, specificity and sensitivity of 97.9% ± 0.14, 98.33% ± 0.03 and 95.24% ± 0.08, respectively, for lumbar spine dataset and 99.3% ± 0.16%, 99.2% ± 0.13 and 100, respectively, for femoral neck dataset. Further, its performance is compared using receiver operating characteristics analysis and Wilcoxon signed-rank test. The results proved that the proposed classifier is efficient and it outperformed the other approaches in all the cases.

Efficacy of an activity monitor as a biofeedback device in cerebral palsy.

BACKGROUND: Assessment of physical outcomes in patients with cerebral palsy (CP) is considered an effective way to monitor their progress, evaluate interventions and guide health care policy. However, no study using an activity monitor (AM) as a biofeedback device in treatment of people with CP has been published. Hence, the objective of this study was to evaluate the use of the AM as a biofeedback device in individuals with CP after a type of single-event multilevel surgery (SEMLS) called Single-Event Multilevel Lever Arm Restoration and Anti-Spasticity Surgery (SEMLARASS). METHOD: A randomized, controlled trial was conducted among 40 individuals with CP in the age group between 10 to 20 years who underwent SEMLARASS. They were randomly assigned to two groups: Group A (n = 20) and Group B (n = 20). Both groups received intensive rehabilitation including different types of activity-based training for around three hours per day. Both groups were assessed with standard subjective outcomes (Physician Rating Scale (PRS), Dynamic Gait Index (DGI) and Functional Mobility Scale (FMS)) and objective outcomes with the use of an AM (IntenzLife, Model No. 56084-1) for measuring step count, distance walked and calories used. During the intervention, for Group A, they were also given an AM after presetting individualized stride length and body weight, to monitor their daily activity levels. The AM was worn around the neck of the person throughout the day and provided a daily report of the measurements and acted as a biofeedback device for individuals with CP who were given specific targets to achieve on a weekly basis. Both groups were evaluated before and after eight weeks of intensive rehabilitation. RESULTS: Group A showed significant differences in the scores of step count (p < 0.001), distance walked (p < 0.001), PRS (p < 0.001), DGI (p < 0.010) and FMS (p < 0.001) when compared to Group B after intensive rehabilitation. However, the calories used (p < 0.086) was not significantly different. CONCLUSION: The AM, which is considered to be a valid and reliable tool for assessing the level of physical activity in CP, can also be used as a biofeedback device for improving specific walking parameters in persons with CP post-SEMLARASS.

Effectiveness of a low-cost body weight support training device in the rehabilitation of cerebral palsy.

BACKGROUND: Body weight supported treadmill training (BWSTT) has been proven to be effective in rehabilitation of persons with cerebral palsy (CP). However, it has still not found widespread usage, especially in industrially developing countries, due to its high cost. Treadmill training promotes a rhythmical movement of the lower extremities through motor learning, which can be enhanced by BWSTT for persons with CP. Hence, the research and development team of a tertiary level neuromusculoskeletal rehabilitation center designed a low-cost body weight support training (BWST) device. The aim of this study was to evaluate the effectiveness of the BWST device on gait and ambulation in persons with CP post single-event multilevel surgery (SEMLS) of the lower extremities. METHOD: A randomized controlled trial was conducted in 50 persons with CP aged between 5 and 20 years, who underwent a type of SEMLS called single-event multilevel lever arm restoration and anti-spasticity surgery (SEMLARASS). They were randomly assigned to two groups: group A (n = 25) received gait training and treadmill training with the BWST device, and group B (n = 25) received gait training and treadmill training without the BWST device. The designed BWST device was manually operated and based on an un-weighing principle in which a vest of different sizes un-weighed 10-30% of the individual's weight transmitted to the ground by means of adjustable counterweights fixed on a movable metallic frame which had an adjustable top lever (holding the vest) and a handle bar for the patient to hold. The entire cost for the finished BWST device was estimated around 700 USD. The study duration was 5 weeks with 1 h of intervention per day for 6 days per week. Physician Rating Scale (PRS), Dynamic Gait Index (DGI) and Functional Mobility Scale (FMS) were the primary outcome measures. RESULTS: Group A showed significant positive differences in the scores of PRS (p < 0.001), DGI (p < 0.001) and FMS (p < 0.01) when compared with group B, 5 weeks after the intervention, and the results were maintained at a follow-up of 12 months. CONCLUSION: The low-cost BWST device was found to be clinically effective in improving gait and ambulation in persons with CP following SEMLARASS.
