Abstract Introduction The Mushtaq Method is a new shoulder reduction technique. It is a simple, reliable, and less traumatic time modulated procedure. Method Patients are placed in the supine position if plausible. Fully adducting the affected arm with the elbow at right angle. The practitioner applies gentle traction above the elbow with the other hand placed deep into the axilla, palpation of the humeral head is followed by lateral pressure resulting in a successful relocation. Internal rotation and a broad arm sling complete the technique. No assistants are needed, and simple analgesia was often enough. Results 95% had a successful reduction within 5 minutes. 75% required analgesia alone, and no periprocedural complications were observed. Conclusions With so many options already, available it is essential to understand what dictates the success and failures of these methods. We have a new, safe, easy to use method requiring minimal force. We hope to increase our cohort size in the future to draw firm conclusions.

Glenohumeral Dislocation

Luxatio erecta is a description for a specific and rare type of shoulder dislocation where the humeral head dislocates directly inferior. This rare form of glenohumeral dislocation accounts for only 0.5% of shoulder dislocations. It is even less common for both shoulders to be bilaterally dislocated inferiorly with the characteristic “hands up” posture. A limited number of these bilateral occurrences are described in the literature to date and most have been from higher energy trauma. We have described a low energy case of bilateral luxatio erecta and the reduction method used and the continued instability following successful reduction under procedural anesthesia.

Invasive Method

The most physiologic and low invasive method for reduction of anterior shoulder dislocation is Dzhanelidze technique that has been proposed in about 100 years ago. However this technique is not often applied in practical work. The authors have analyzed the efficacy of original Dzhanelidze technique at treatment of 6 patients and its popularity among practical trauma- and orthopaedic surgeons (n=54) from different hospitals in Vladivostok and Primorski Territory. It is shown that original shoulder dislocation reduction technique by Dzhanelidze without morphine use is not effective. Out of all surgeons who participated in questionnaire survey only 10 (18.5%) specialists apply Dzhanelidze method in practice. Physicians use various modifications of this method that considerably differ from the original technique. Description of Dzhanelidze technique in modern textbooks and manuals of surgery and traumatology are contradictory and significantly differ from the author’s technique.

AbstractIn this study, the hourly directions of eight banking stocks in Borsa Istanbul were predicted using linear-based, deep-learning (LSTM) and ensemble learning (LightGBM) models. These models were trained with four different feature sets and their performances were evaluated in terms of accuracy and F-measure metrics. While the first experiments directly used the own stock features as the model inputs, the second experiments utilized reduced stock features through Variational AutoEncoders (VAE). In the last experiments, in order to grasp the effects of the other banking stocks on individual stock performance, the features belonging to other stocks were also given as inputs to our models. While combining other stock features was done for both own (named as allstock_own) and VAE-reduced (named as allstock_VAE) stock features, the expanded dimensions of the feature sets were reduced by Recursive Feature Elimination. As the highest success rate increased up to 0.685 with allstock_own and LSTM with attention model, the combination of allstock_VAE and LSTM with the attention model obtained an accuracy rate of 0.675. Although the classification results achieved with both feature types was close, allstock_VAE achieved these results using nearly 16.67% less features compared to allstock_own. When all experimental results were examined, it was found out that the models trained with allstock_own and allstock_VAE achieved higher accuracy rates than those using individual stock features. It was also concluded that the results obtained with the VAE-reduced stock features were similar to those obtained by own stock features.

AbstractRadial head subluxation (RHS) is the most common upper extremity injury in children. Supination–flexion (SF) and hyperpronation (HP) are two methods for reducing this subluxation. This study purposed to compare the success rates of two methods of reduction and also to determine which technique would be less painful. In total, 154 patients with RHS were enrolled in this study and randomized into two groups. Patients were to undergo reduction by one of the two methods; if the primary attempt was unsuccessful, a second attempt was performed using the alternate technique. In the case of failure of the second attempt, the first reduction technique was repeated. The success rates and pain levels before and after successful reduction were recorded. On the first attempt, 72 of 77 patients who underwent HP had a successful reduction. Four patients in the HP group had a successful reduction on the second attempt. In the SF group, 76 of 77 patients had a successful reduction on the first attempt. The success rate on first attempts was higher in the SF group than in the HP group (p = 0.043). Pain levels before and after reduction were not statistically different between the groups (p > 0.05). The SF technique had a higher success rate at first attempt to reduce RHS, but pain levels were similar in both methods.

Background/Objectives: In order to minimize the damage and malfunction of the equipment and system from various surges, we studied the method of reducing the residual voltage according to the lead wire length of the surge protector.Methods/Statistical analysis: In buildings, SPD installation space is insufficient or narrow, resulting in longer lead wire of SPD, and SPD protection performance is decreased due to increase of voltage protection level and residual voltage. In this study, the voltage protection level and the residual voltage of the conventional SPD model and the proposed SPD model are analyzed according to the change of the connecting conductor length from 0.5to 100m.Findings: In the case of the conventional SPD model, the protection level of the SPD is excellent by measuring the voltage protection level at 1,410V even if the lead wire length of the connecting conductor is changed to 10m, but when it exceeds 10m, the protection performance and the protection cooperation are reduced. On the other hand, in the case of the proposed SPD model, the voltage protection level was measured to be 50 V or less even if the lead wire length of the connecting conductor was changed to100 m. Therefore, it is considered that SPD protection performance and protection cooperation are excellent.Improvements/Applications: The design technique of SPD obtained through this study will help to select the optimal installation site and reduce the budget.
