The efficacy of new neuronal growth factor in the healing of the sciatic nerves in rabbits.

Background and Objective: Regeneration of nervous tissue is unpredictable and an ideal growth factor to influence the healing of the injured nerves is not available. A recent study in rats had shown that a new neuronal growth factor (NNGF) was effective in the early healing of the sciatic nerves. The aim of this experimental study is to test the efficacy of NNGF in the healing of iatrogenic division of the sciatic nerves in a larger animal (rabbits). Methods: White New Zealand 20 male rabbits of 6 months of age were divided into two groups. Intramuscular ketamine and xylazine were used to anesthetize the animals. The sciatic nerves were divided using scalpel blade 15 and 10/0 Vicryl was used to repair the divided neural tissue. In the study group, 10 mg/kg body weight of NNGF was instilled on the top of the divided nerves and the wound was closed. At 4 weeks, the operated limbs were observed for any trophic skin changes. Nerve conduction studies were carried out using train-of-four-Watch SX, Organon (Ireland) Ltd., and Ireland. The rabbits were put to death humanely and the sciatic nerves were removed and delivered to the pathologist in 2% formalin. The pathologists were blinded about the two groups. Results: Electromyographic study done at 4 weeks showed in the untreated group; the mean twitches 1-T4 was 0.45 ± 0.31% and in the treated group, the average was 77.912 ± 5% (P > 0.001). Microscopic anatomy in the treated group revealed prominent healing by regeneration was evidenced by showing growth of its proximal segments into an empty endoneurial tube which was not seen in the control group. In the control group, the nerves showed no histological element of healing by regeneration. Conclusions: NNGF proves that in a larger animal at 4 weeks profoundly influenced early regeneration of experimentally created divisions of myelinated nerve tissue.

Résumé Contexte et objectif: La régénération des tissus nerveux est imprévisible et un facteur de croissance idéal pour influencer la guérison des nerfs blessés n'est pas disponible. Une étude récente chez le rat a montré qu'un nouveau facteur de croissance neuronal (NNGF) était efficace dans la guérison précoce des nerfs sciatiques. L'objectif de cette étude expérimentale est de tester l'efficacité du NNGF dans la guérison de la division iatrogène des nerfs sciatiques chez un animal plus grand (lapin). Méthodes: White New Zealand 20 lapins mâles de 6 mois ont été divisés en deux groupes. La kétamine intramusculaire et la xylazine ont été utilisées pour anesthésier les animaux. Les nerfs sciatiques ont été divisés en utilisant la lame scalpel 15 et 10/0 vicryl ont été utilisés pour réparer le tissu neural divisé. Dans le groupe d'étude, 10 mg / kg de poids corporel du NNGF ont été inculqués sur le dessus des nerfs divisés et la plaie a été fermée. À 4 semaines, les membres opérés ont été observés pour tout changement de peau trophique. Des études de conduction nerveuse ont été menées à l'aide de SX Train-of-Nat-Watch, Organon (Ireland) Ltd. et Ireland. Les lapins ont été mis à mort avec humanité et les nerfs sciatiques ont été retirés et livrés au pathologiste dans 2% de formol. Les pathologistes ont été aveuglés sur les deux groupes. Résultats: électromyographique L'étude réalisée à 4 semaines a montré dans le groupe non traité; Les contractions moyennes 1 à T4 étaient de 0,45 ± 0,31% et dans le groupe traité, la moyenne était de 77,912 ± 5% (p> 0,001). L'anatomie microscopique dans le groupe traité a révélé une guérison importante par régénération a été mise en évidence en montrant la croissance de ses segments proximaux dans un tube endoneurial vide qui n'a pas été observé dans le groupe témoin. Dans le groupe témoin, les nerfs n'ont montré aucun élément histologique de guérison par régénération. Conclusions: NNGF prouve que chez un animal plus grand à 4 semaines, a profondément influencé la régénération précoce des divisions créées expérimentalement du tissu nerveux myélinisé.

Quality of life post total knee arthroplasty: Saudi Arabian experience.

Background and Objective: Osteoarthritis of knee is quite common in Saudi Arabian population. Total knee arthroplasty (TKA) was reluctantly accepted in Saudi Arabia about 2 decades ago but there are few small number reports on quality of life (QOL) postsurgery. The objective of this study was to investigate the QOL and overall satisfaction postTKA. Methods: We retrospectively studied 200 patients' consecutive patients who underwent primary TKA at King Fahd Hospital of the University, AlKhobar, Saudi Arabia. Patient's age, sex, weight, height, body mass index, and range of movements at the time of surgery were extracted from the QuadraMED patients Database. The minimum follow-up was 24 months. At the last visit of 24 months, patients were evaluated using modified Western Ontario and McMaster Universities Osteoarthritis Index (MWOMAC), QOL using Short Form-36 Health Survey (SF-36), and patient satisfaction was assessed. Results: Among the 212 TKAs performed, 52 were male and 148 were female. One hundred and twenty two were right side and 90 were left side and 22 were bilateral. The mean age was 62.7 ± 5.1 years. There were no intraoperative complications. Nearly 95% resulted in patient satisfaction. SF-36 and all the parameters assessed significantly improved (P < 0.001). MWOMAC scores of the patients, which show all functions, had statistically significantly improved to (P < 0.001) except prayers before and after surgery did not change which was expected. The overall level of satisfaction was observed 95% of patients. Conclusions: Our study shows that TKA has a positive effect on pain, mobility, QOL, and ultimate satisfaction.

RésuméContexte et objectif: L'arthrose du genou est assez courante dans la population saoudienne. L'arthroplastie totale du genou (PTG) a été à contrecoeur accepté en Arabie saoudite il y a environ 2 décennies, mais il existe peu de rapports sur la qualité de vie (QOL) après la chirurgie. L'objectif de ce étude était d'étudier la qualité de vie et la satisfaction globale après PTG.

Autologous Bone Marrow-Derived Chondrocytes for Patients with Knee Osteoarthritis: A Randomized Controlled Trial.

RESULTS: There were a total of 60 patients who were followed up. Three patients in Group II were removed from the analysis as they underwent total knee arthroplasty (TKA). A notably significant improvement was noticed in the ABMDC group on all scores of VAS and MKSSSF with P < 0.0001. The control group continued to be dissatisfied with the treatment they were taking. CONCLUSIONS: This study reveals that a single injection of 5 million of ABMDC was efficient in reducing the symptoms, improving the functional score and betterment of QOL.

Prevalence of surgical site infection in orthopedic surgery: a 5-year analysis.

Surgical site infection (SSI) is disastrous in orthopedic practice as it is difficult to rid the bone and joint of the infection. This study was aimed to assess the prevalence of SSI in orthopedic practice and to identify risk factors associated with surgical site infections. All patients admitted to the orthopedic male and female wards between January 2006 and December 2011 were included in the study group. The data, which were collected from the medical charts and from the QuadraMed patient filing system, included age, sex, date of admission, type of admission (elective versus emergency), and classification of fractures. Analyses were made to find out the association between infection and risk factors, the χ (2) test was used. The strength of association of the single event with the variables was estimated using Relative Risk, with a 95% confidence interval and P < 0.05. A total of 79 of 3096 patients (2.55%) were included: 60 males and 19 females with the average age of 38.13 ± 19.1 years. Fifty-three patients were admitted directly to the orthopedic wards, 14 were transferred from the surgical intensive care unit, and 12 from other surgical wards. The most common infective organism was Staphylococcus species including Methicillin Resistant Staphylococcus aureus (MRSA), 23 patients (29.11%); Acinetobacter species, 17 patients (21.5%); Pseudomonas species, 15 patients (18.9%); and Enterococcus species, 14 patients (17.7%). Fifty-two (65.8%) had emergency procedures, and in 57 patients trauma surgery was performed. Three (3.78%) patients died as a result of uncontrolled septicemia. SSI was found to be common in our practice. Emergency surgical procedures carried the greatest risk with Staphylococcus species and Acinetobacter species being the most common infecting organisms. Proper measures need to be undertaken to control infection rates by every available method; antibiotics alone may not be sufficient to win this war.

Can double gloves improve surgeon-patient barrier efficiency?

The aim of this study was to compare double gloves (DGs) with single gloves (SGs) during orthopedic and trauma surgery in prevention of blood contact between patients and surgeons. DGs and SGs were collected after orthopedic operations, tested for size, site, and number of perforations. Medical records were reviewed for age, sex, type of operation, duration, and postoperative wound infection. Data were compared using t-test with level of statistical significance at P < 0.05. Five hundred seven operations yielded 1204 DGs and 830 pairs SGs. In DGs, perforations were detected in 220 outer glove and 39 inner glove (10.7%). In SGs, 226 perforations were detected (13.3%). The incidence of perforations in inner gloves of the double indicator glove was 1.6% (P < 0.001). During surgery, perforations were recognized in DGs in 67% compared with 12% in SGs (P < 0.005). This study confirms that DGs form an efficient barrier between patients and surgeons.
