Making a Psychological Help to be used Through Intraoperative Strength Failures.
We present an example workflow of all data preparation steps. In a case study using data from water monitoring sites in Southern Germany, the resulting stream network and derived site characteristics matched those constructed using STARS, an ArcGIS custom toolbox. An advantage of openSTARS is that it relies on free and open-source GRASS GIS and R functions, unlike the original STARS toolbox which depends on proprietary ArcGIS. openSTARS also comes without a graphical user interface, to enhance reproducibility and reusability of the workflow, thereby harmonizing and simplifying the data pre-processing prior to statistical modelling. Overall, openSTARS facilitates the use of spatial regression and other applications on stream networks and contributes to reproducible science with applications in hydrology, environmental sciences and ecology.
Lobar lymph node metastases in non-primary tumor-bearing lobes (NTBL) are rarely reported. This study examined the risk factors of lobar lymph node metastasis in NTBL.

We retrospectively studied 301 patients with non-small-cell lung cancer (NSCLC) who underwent surgical pulmonary resection with systematic lymph node dissection plus extended lobar lymph node dissection of NTBL. Patients were classified into positive and negative NTBL groups. Unconditional logistic regression was used to identify the risk factors for lobar lymph node metastasis in NTBL.

NTBL lobar lymph nodes were identified in 38 patients (12.6%). A higher proportion of adenocarcinomas occurred in the positive NTBL group compared to the negative NTBL group (73.7% vs. 46.4%, P = 0.01). Risk of NTBL lobar lymph node metastases was significantly elevated in the lower lobe of primary site compared to the upper lobe (OR = 2.61, 95% CI = 1.26-5.75, P = 0.01), and with adenocarcinomas compared to squamous cell carcinomas (OR = 2.75, 95% CI = 1.09-7.65, P = 0.04). No differences were observed when comparing left and right lobes. NTBL lobar lymph node metastasis was most often observed among patients with larger tumor size, N1/N2 nodal involvement, with lymph vascular invasion (LVI), and visceral pleural invasion (VPI).

NTBL lobar lymph node metastases occurred more often in patients with a primary NSCLC tumor in the lower lobe, with adenocarcinomas, larger tumor size, N1/N2 nodal involvement, LVI or VPI. Extended lymphadenectomy including NTBL nodes may be clinically advantageous when these risk factors are present.

The classical clinical finding is substantial nocturnal pain and imaging findings. The management of osteoid osteomas include open surgical excision or minimally invasive percutaneous interventions. Why and which treatment modality should be considered between CT-guided radiofrequency ablation and open surgical excision for osteoid osteomas in unusual locations? MATERIAL AND METHODS We retrospectively reviewed 17 patients with osteoid osteomas in unusual locations included cuboid, triquetrum, coronoid process, and proximal phalanx. We evaluated the duration from symptoms to diagnosis, activity related pain, clinical findings, and possible recurrence or complications. The minimum clinical follow-up was 51 ± 34.8 months. RESULTS CT-guided radiofrequency ablation was applied to 3 patients and open surgical excision procedures to 14. All the complaints of patients gone after treatment. No mion. Which management modality is superior may change depending on the location of the lesion between CT-guided radiofrequency ablation and surgical excision. Key words osteoid osteoma, unusual locations, CT guided, radiofrequency ablation, benign bone tumor.PURPOSE OF THE STUDY Unsatisfactory functional results following hemiarthroplasty (HA) are seen in the treatment of 3- and 4-part proximal humeral fractures due to tuberosity healing problems and rotator cuff tears. Reverse shoulder arthroplasty (RSA) has been popular for improving functional outcomes. This study compares the results of HA and RSA in the treatment of comminuted proximal humeral fractures in the elderly. MATERIAL AND METHODS Patients over 60 years of age with three- or four-part proximal humeral fractures were included in the study. Twenty-five patients were treated with HA and 33 patients with RSA. The patients were evaluated with/using the American Shoulder and Elbow Surgeons (ASES) and Constant scores, active and passive ranges of motions of the shoulders and muscle strength measurements of HA and RSA patients were compared. RESULTS The mean age of the patients was 66 (60-85) years in the HA group and 73 (60-83) years in the RSA group. The mean ASES and Constant scores were 44.6 and 70 (p=0.06), 24 and 49 (p=0.022), respectively. The mean active abduction was measured as 50° and 90° (p=0.001), flexions as 70° and 120° (p=0.02), and external rotation as 30° and 50° (p=0.210), respectively. CONCLUSIONS In the treatment of three- or four-part proximal humeral fractures of the elderly, RSA gives significantly better functional results compared to HA. Key words proximal humeral fractures, hemiarthroplasty, reverse shoulder arthroplasty.PURPOSE OF THE STUDY In this study it is aimed to prospectively evaluate the safety and efficacy of 20 mg/2 ml Hyaluronic Acid (HA) injections for non-operative palliation treatment of osteoarthritis (OA) of the knee joint. MATERIAL AND METHODS After institutional review board approval was obtained for the study, 63 patients were enrolled and followed prospectively. All the patients have signed informed consent form. Patients who had diagnosis of gonarthrosis according to clinical and radiological evaluation, were given nonsteroid antiinflammatory drug (NSAID) treatment for four weeks. Patients between 55-80 years old in both sexes, whose pain did not relieve were included to the study and were followed up for 6 months. They were applied HA injections in total; three times with one week of interval. Patients were evaluated three times during the study. First one at third week (at the control visit of third injection), secondly at third month and lastly at sixth month.

The purpose of this study was to provide a comparative evaluation of complications in the treatment of trochanteric fractures using 2-screw proximal femoral nail versus proximal femoral anti-rotational blade nail. MATERIAL AND METHODS A retrospective review was conducted between March 2013 and March 2019. The study included 519 patients (358 females and 161 males) treated surgically for trochanteric fractures. The mean age was 79.8±12.0 (24-100) years. A1.2 type of fracture occurred in 153 (29.5%) cases, A1.3 type in 155 (29.9%), A 2.2 type in 90 (17.4%), A2.3 type in 95 (18.3%), A3.1 type in 11 (2.1%), A3.2 type in 7 (1.3%) and A3.3 type in 8 (1.5%) cases. Patients were treated either by 2-screw nail PFN (393 patients (75.7%) or by anti-rotational blade nail PFNA (126 patients (24.3%). RESULTS Our primary objective wew implant is used. When antirotational blade is used, compression of spongiosis around blade is observed, which increases stability, especially in an osteoporotic bone. In our study, complications in these two types of nails were retrospectively compared. Considered as the limitation of our study is the retrospective nature of evaluation, which made it impossible the create two study groups with equal or similar number of patients, to follow up the patients postoperatively for a long period of time and to evaluate fracture union and limb function. CONCLUSIONS In our study no statistically significant difference in postoperative mechanical and infectious complications was confirmed between the 2-screw proximal femoral nail and the proximal femoral nail with antirotational blade. We have arrived at the conclusion that both types of nails are equivalent in treating trochanteric fractures. Key words intramedullary nail, screw, blade, trochanteric fracture, complication.PURPOSE OF THE STUDY The study gives a retrospective assessment of the outcomes of surgical treatment in patients who sustained a subtrochanteric fracture. MATERIAL AND METHODS In the period 2010-2018, a total of 118 patients with a subtrochanteric fracture, namely 75 males and 43 females, the mean age 61 years, were treated at our department. The study group included the patients who met the following inclusion criteria age 18+, fracture treated by intramedullary nailing, follow-up for at least 12 months, in case of impaired healing and need for revision surgery follow-up until complete healing was achieved. Exclusion criteria - pathological fractures, periprosthetic fractures, pertrochanteric fractures with extension into subtrochanteric region, intertrochanteric fractures, fractures during bisphosphonate treatment, incomplete radiological documentation, non-compliance with the condition of 12-month follow-up. In 54 patients (46%) the injury was caused by high-energy impact, in the remaining 64 patients (54he most commonly used are the intramedullary implants. Displacement to varosity, flexion displacement or a combination of both cause impaired healing with non-union and failed osteosynthesis. Treatment of non-union is extremely challenging and always consists in the correction of anatomical relationships. Key words subtrochanteric fractures, surgical treatment, outcomes, complications.PURPOSE OF THE STUDY This study is a component part of the project focused on cartilage imaging after the treatment of a defect. It aims to compare the evaluation of postoperative status performed by two radiologists with the use of 2D MOCART scoring system and to determine whether this method is a reliable tool for the evaluation of postoperative changes. MATERIAL AND METHODS The study evaluated 78 MRI examinations from 25 patients (one patient had two defects treated), each of whom underwent 3 MRI examinations at 6, 12 and 18 months after surgery. The MRI examinations were performed on Philips Ingenia 3T scanner with 8-channel knee coil, in line with the routine protocol (coronal, sagittal and transversal PD SPAIR, coronal T1, sagittal PD HR, sagittal bFFE). The MRI examinations were evaluated independently by two radiologists using the 2D MOCART (Magnetic Resonance Observation of Cartilage Repair Tissue) score. RESULTS The raters agreed in a total of 592 of 702 evaluations, therefore the inter-rater reliabeported in the evaluation of effusion, where in some cases, its volume was underestimated, when traced back retrospectively. CONCLUSIONS The results of this study confirm that despite certain doubts regarding subjective perception of some of the evaluation criteria the 2D MOCART scoring system is a very good and objective tool to evaluate the effects of surgery. Key words magnetic resonance imaging , hyaline cartilage, classification.
