Inequitable access to Ebola vaccines and the resurgence of Ebola in Africa: A state of arts review.

The Ebola virus, a member of the filoviridae family of viruses, is responsible for causing Ebola Virus Disease (EVD) with a case fatality rate as high as 50%. The largest EVD outbreak was recorded in West Africa from March 2013 to June 2016, leading to over 28 000 cases and 11 000 deaths. It affected several countries, including Nigeria, Senegal, Guinea, Liberia, and Sierra Leone. Until then, EVD was predominantly reported in remote villages in central and west Africa close to tropical rainforests. Human mobility, behavioral and cultural norms, the use of bushmeat, burial customs, preference for traditional remedies and treatments, and resistance to health interventions are just a few of the social factors that considerably aid and amplify the risk of transmission. The scale and persistence of recent ebola outbreaks, as well as the risk of widespread global transmission and its ability for bioterrorism, have led to a rethinking of public health strategies to curb the disease, such as the expedition of Ebola vaccine production. However, as vaccine production lags in the subcontinent, among other challenges, the risk of another ebola outbreak is likely and feared by public health authorities in the region. This review describes the inequality of vaccine production in Africa and the resurgence of EVD, emphasizing the significance of health equality.

Pyrocarbon Lunate Replacements Perform Well at Two Years: A Retrospective Case Series and Technique from Two UK Tertiary Centres.

Background: We report medium-term results in our case series of patients with Kienböck disease receiving a pyrocarbon lunate replacement (Integra, Smith and Nephew, Watford, UK). Methods: Patients with Kienböck receiving a pyrocarbon lunate between September 2012 and November 2020, with stage 3b and above were included. Patients were staged preoperatively with radiographs and MRIs. Pre- and postoperative visual analogue scores and movement were documented. Postoperative radiographs were obtained at 6 weeks, 6 months and 1 year. Results: Seven patients were identified, all female, with a median age of 28.0 years. All but one had 3b disease and the median follow-up was 2 years (range 13-112 months). A mean 9/10 preoperative VAS score improved to 1/10 by 3 months postoperatively (p < 0.001, paired t-test). No major complications were seen, and implants were stable radiologically. Conclusions: A semi-constrained pyrocarbon lunate can provide good results for patients with advanced Kienböck's disease, offering an alternative to proximal row carpectomy salvage surgery. Level of Evidence: Level IV (Therapeutic).

Correlation between the length from the elbow to the distal interphalangeal joint of the little finger and the length of the intramedullary nail selected for femoral fracture fixation.

AIM: To determine whether there is a correlation between the length of forearm to the distal interphalangeal joint (DIPJ) of the little finger and length of antegrade intramedullary (IM) femoral nails in adults. STUDY DESIGN AND METHODS: Measurements from the tip of the olecranon to the DIPJ of the ipsilateral upper limb was taken in 30 patients undergoing antegrade IM femoral nails. The length of the IM nails inserted was determined by intra-operative measurements using a guide wire. The two measurements were analysed for correlation and mean difference. RESULTS: The mean forearm to DIP of little finger length was 38.86 with a standard deviation of 2.83. The mean IM length and standard deviation were 38.56 and 2.77 respectively. The difference between the two means 0.3 (95% CI). Correlation testing between the two variables shows a positive relationship (Pearson Correlation factor of 1). The scatter plot shows a positive linear relationship. CONCLUSIONS: Length of the forearm from the tip of the olecranon to the DIP joint of the little finger represents the ideal length of IM nail for the femur. It can be readily performed with the use of a tape measure and can serve as a useful adjunct to determining ideal length in cases where the contralateral femur cannot be used.

Patella resurfacing during total knee arthroplasty: have we got the issue covered?

BACKGROUND: Management of the patella during total knee arthroplasty (TKA) is controversial. Multiple studies have examined mechanical and clinical results of TKA with native and resurfaced patellae with no clear consensus. METHODS: We surveyed a large cohort of consultant surgeons in a questionnaire based study in order to assess the indications for patella resurfacing and to correlate practice with degree of specialization, experience and volume of procedures performed. RESULTS: Six hundred and nineteen surgeons were included. The main indication for patella resurfacing was patellofemoral arthritis. The ratio of those who always:sometimes:never resurfaced was 1:2:1 irrespective of experience or volume performed. There was no difference between knee specialists and non-specialists (p = 0.977) or between high and lower volume surgeons (p = 0.826). Senior and high volume surgeons tended to always resurface. CONCLUSIONS: The majority of surgeons only sometimes resurfaced the patella. The number who always and never resurfaced were similar. There was a tendency for more experienced and high volume surgeons to always resurface.

Injuries associated with recreational horse riding and changes over the last 20 years: a review.

OBJECTIVE: To assess the incidence and distribution of recreational equestrian injuries seen in the Kent and Sussex region and review the available literature on this subject. DESIGN: This is a retrospective case series with historical controls. SETTING: Kent and Sussex region, England. MAIN OUTCOME MEASUREMENT: Injuries related to horses in the recreational setting. METHODS: Subjects were selected from our acute injury database. Notes of all patients presenting with horse riding-related injuries between January and December 2010 were reviewed. Skeletal injuries were confirmed using our Picture Archiving and Communications Systems (PACS) system. Data were tabulated and grouped using Microsoft Excel software. Statistics were calculated using Graph Pad software. RESULTS: During the study period, 155 patients presented with a total of 199 injuries related to horses, accounting for 0.3% of all presentations; 69% were soft tissue injuries. The most commonly affected areas were the extremities (77 patients, 49.7%) followed by injuries to the head (38 patients, 24.5%) and trunk (36 patients, 23.2%). Seventeen patients (11%) were admitted. Patients presenting with head injuries suffered significantly more injuries compared to other groups (1.65 compared to 1.4 injuries, p < 0.0002). CONCLUSION: A larger number of persons were riding for a longer period of the year compared to previous studies in the United Kingdom. There was also a shift in the patterns of injury seen in this population over the last two to three decades.

The use of locking plates in proximal humeral fractures: Comparison of outcome by patient age and fracture pattern.

PURPOSE: This study was undertaken to evaluate the efficacy of a proximal humeral locking plate, and to specifically study the effect of patient age and fracture type on the outcome. MATERIALS AND METHODS: Thirty-one cases of proximal humeral fractures fixed by using the proximal humeral interlocking (PHILOS) plate were reviewed. RESULTS: Average functional scores (minimum 18 months post operation) per AO / ASIF fracture type were 25.3 for type A, 21.4 for type B, and 22.7 for type C. There was no statistically significant difference between the groups. The functional scores for patients over 65 years of age were significantly inferior (P = 0.03). At a final radiological review (mean 12 months post operation), 30 (96%) of the patients demonstrated fracture union. Seven patients (22.5%) required a second surgical procedure. CONCLUSION: We obtained both good functional results and bone healing with the PHILOS plate, irrespective of fracture type; the older patients had a poorer outcome. We caution the surgeons on the high potential for reoperations with its use.
