Therapeutic study, Level I.

BackgroundIn this study, starch and polycaprolactone (PCL), composite nanofibers were fabricated by co-axial needle electrospinning technique. Processing parameters such as polymer concentration, flow rate and voltage had a marked influence on the composite fiber diameter. Fourier transform infrared spectroscopy, scanning electron microscopy (SEM), mechanical and physical properties (such as density, viscosity and electrical conductivity) of the composite fibres were evaluated. Moreover, a cell culture test was performed in order to determine their cytotoxicity for wound dressing application.ResultsThe effect of starch ratio in the solution on the properties and morphological structure of the fibers produced was presented. With lower starch concentration values, the fibers have greater ultimate tensile strength characteristic (mostly 4 and 5 wt%). According to SEM results, it can be figured out that the nanofibers fabricated have good spinnability and morphology. The mean diameter of the fibers is about 150 nm. According to results of cell culture study, the finding can be determined that the increase of starch in the fiber also increases the cell viability.ConclusionsComposite nanofibers of starch/PCL have been prepared using a co-axial needle electrospinning technique. PCL was successfully encapsulated within starch. Fiber formation was observed for different ratio of starch. With several test, analysis and measurement performed, some important parameters such as quality and effectuality of each fiber obtained for wound dressing applications were discussed in detail.

AIMTo evaluate social media usage of orthopaedic patients to search for solutions to their health problems.METHODSThe study data were collected using face-to-face questionnaire with randomly selected 1890 patients aged over 18 years who had been admitted to the orthopaedic clinics in different cities and provinces across Turkey. The questionnaire consists of a total of 16 questions pertaining to internet and social media usage and demographics of patients, patients’ choice of institution for treatment, patient complaints on admission, online hospital and physician ratings, communication between the patient and the physician and its effects.RESULTSIt was found that 34.2% (n = 647) of the participants consulted with an orthopaedist using the internet and 48.7% (n = 315) of them preferred websites that allow users to ask questions to a physician. Of all question-askers, 48.5% (n = 314) reported having found the answers helpful. Based on the educational level of the participants, there was a highly significant difference between the rates of asking questions to an orthopaedist using the internet (P = 0.001). The rate of question-asking was significantly lower in patients with an elementary education than that in those with secondary, high school and undergraduate education (P = 0.001) The rate of reporting that the answers given was helpful was significantly higher in participants with an undergraduate degree compared to those who were illiterate, those with primary, elementary or high school education (P = 0.001). It was also found that the usage of the internet for health problems was higher among managers-qualified participants than unemployed-housewives, officers, workers-intermediate staff (P < 0.05).CONCLUSIONWe concluded that patients have been increasingly using the internet and social media to select a specific physician or to seek solution to their health problems in an effective way. Even though the internet and social media offer beneficial effects for physicians or patients, there is still much obscurity regarding their harms and further studies are warranted for necessary arrangements to be made.

IntroductionSynovial chondromatosis is a mono-articular arthropathy rarely seen in diarthrodial joints. The classic treatment for synovial chondromatosis is open arthrotomy, synovectomy and complete removal of the free fragments. With recent advances in arthroscopic techniques and methods, the indications for arthroscopic treatment have been extended.Presentation of caseA 33-year old female presented with complaints of pain in the right shoulder. On the radiological examination, there were seen to be multiple calcified radio-opaque lesions filling all area of the glenohumeral joint. On computed tomography (CT) examination, again multiple radio-opaque free fragments were determined. Arthroscopy was applied to the right shoulder. The free fragments were completely removed. Approximately 33 free fragments, ranging in size from 0.5 to 1.3 cm, were removed.DiscussionCases of synovial chondromatosis in the shoulder have been rarely reported in literature. Generally the disease is self-limiting. Clinically, symptoms are generally not specific. Restrictions in the joint range of movement occur associated with the mechanical effect of the free fragments and in periods of active use, local pain and swelling may be seen in the shoulder. Simple removal of the free fragments, others have stated that removal with synovectomy is necessary to prevent recurrence of the cartilaginous metaplastic focus. Recurrence rates vary from 0 to 31%.ConclusionArthroscopic surgery can be successfully applied in the treatment of synovial chondromatosis. The advantages of the method include good visualisation during surgery, low morbidity and early healing.

DDH is still common among newborns in Turkey. Hip US is recommended for detection and follow-up of DDH in newborns.
