RESUMO

OBJECTIVES: Hip fractures are increasingly common among the elderly population, who often present with a high burden of comorbidities necessitating preoperative stabilization. As a result, preoperative cardiology consultations are frequently conducted in clinical practice. The aim of this study was to investigate the additional recommendations provided by preoperative cardiology consultations and the impact of consultations on the management and outcomes of elderly patients undergoing hip fracture surgery. PATIENTS AND METHODS: This matched cohort study was performed to retrospectively assess the clinical data of patients who were treated for hip fractures at our institution between January 2016 and December 2017. Individuals who were 60 years old or older with available clinical and radiological data were included. A total of 262 patients who met these criteria were included, with 192 undergoing cardiology consultation and 70 not. Through matching for age, sex, ASA grade, fracture type, and surgery type, two groups (Group A, preoperative cardiology consultation requested; Group B, preoperative cardiology consultation not requested) of 50 patients each were formed. The duration between hospital admission and surgery, recommendations provided by cardiology consultation, type of anaesthesia and surgery, length of hospital stay, incidence of medical and orthopaedic complications, and one-year mortality status were compared between the groups. RESULTS: The mean age of Group A was 78.5 (± 7.4) years, whereas that of Group B was 78.4 (± 7.4) years (p = 0.99). Both groups included 30 female patients and 20 male patients each. There were no significant differences in anaesthesia type or the incidence of medical or orthopaedic complications between the groups. However, Group A experienced a significantly longer duration between admission and surgery (5 [1/9] days vs. 3 [0/7] days; p = 0.00) and a longer hospital stay (7 [3/15] days vs. 5 [1/19] days; p = 0.01) than did Group B. The one-year mortality rate did not significantly differ between the groups (30% vs. 20%; p = 0.36). Notably, only 3 out of 50 patients received additional treatments following cardiology consultation beyond routine recommendations. CONCLUSION: Preoperative cardiology consultations before hip fracture surgery rarely leads to a change in treatment. Additionally, these evaluations delay surgery and extend the hospital stay.

RESUMO

INTRODUCTION: In total knee arthroplasty (TKA), choosing the correct implant size is important. There is lack of data on accuracy of templating on haemophilic knees. Our aim was to test the accuracy of 2D digital templating for TKA on haemophilic arthropathy (HA) of knee. MATERIALS AND METHODS: TKAs performed on HA between January 2011 and January 2022 were screened. Osteoarthritis (OA) group was created as control group by a one-to-one matching regarding type of implant used. Intra- and interobserver correlations were measured in HA, then correlation between templated and implanted sizes was investigated in four assessments (femur AP, femur lateral, tibia AP, tibia lateral), then compared with OA group. Fifty-eight knees in each group included. RESULTS: Regarding intraobserver correlation in HA, there was excellent correlation for femur AP [.93 (.73-.98)], femur lateral [.98 (.91-.99)], and tibia AP (1.0) templating. Regarding interobserver correlation in HA, excellent correlation was observed for femur lateral [.93 (.74-.98)] and tibia AP templating [.90 (.65-.97)]. Regarding correlation of templated and applied sizes in HA; tibia AP, tibia lateral and femur lateral templating showed good correlation [.81 (.70-.89), .86 (.77-.91), .79 (.67-.87) while femur AP templating showed moderate correlation [.67 (.50-.79)]. Comparing HA and OA, there was no difference in correlation levels regarding femur AP, femur lateral, tibia AP and tibia lateral templating (p = .056, p = .781, p = .761, p = .083, respectively). CONCLUSION: Although 2D digital templating shows comparable correlation in HA and OA, clinical applicability of templating on HA appears to be limited in its current state.

RESUMO

Introduction: Medial open wedge high tibial osteotomy is a biological procedure for treating unicompartmental knee osteoarthritis. The literature repeatedly highlights the significance of preserving an intact lateral hinge during this procedure. We investigated the temporal course of distraction forces during distraction at the osteotomy site, aiming to quantitatively measure and analyse temporal changes in distraction forces at different distraction points for intact and fractured lateral hinges. Materials and Methods: This biomechanical study was conducted on 10 human cadavers, which were divided into two groups: one with preserved 1 cm intact lateral cortexes (ILCs) and the other with completely osteotomised fractured lateral cortexes (FLCs). An experimental setup was custom designed to facilitate the required force measurement during distraction. The distraction forces were recorded with a force gauge at 0.5-mm intervals throughout the distraction. Results: There was a significant difference between the ILC and FLC groups in distraction forces at all points (8-15 mm). The ILC group consistently exhibited higher distraction force values, with FLC recording values ranging from 8.8% to 13.2% of ILC's. Lateral hinge fractures caused an 86.7% reduction in the initial required force for distraction, significantly impacting the force required for distraction. The ILC group displayed a linear increase in the required distraction force up to 12.5 mm of distraction, which reached 3.7 times the initial value at 12.5 mm of distraction. The FLC group had lower baseline required distraction forces, following a relatively linear trend with more limited increases. Conclusion: FLCs in medial opening wedge osteotomy are associated with significant reductions in the force required for distraction, and a sudden decrease in distraction force during distraction may indicate a lateral hinge fracture. Force measurement devices for use during distraction could offer valuable insights and provide surgeons with immediate warnings for LHFs. Level of Evidence: Level IV.

RESUMO

Study Design: Pre-clinical animal experiment. Objective: In this study, we investigated therapeutic effects of silibinin in a spinal cord injury (SCI) model. In SCI, loss of cells due to secondary damage mechanisms exceeds that caused by primary damage. Ferroptosis, which is iron-dependent non-apoptotic cell death, is shown to be influential in the pathogenesis of SCI. Methods: The study was conducted as an in vivo experiment using a total of 78 adult male/female Sprague Dawley rats. Groups were as follows: Sham, SCI, deferoxamine (DFO) treatment, and silibinin treatment. There were subgroups with follow-up periods of 24 h, 72 h, and 6 weeks in all groups. Malondialdehyde (MDA), glutathione (GSH), and Fe2+ levels were measured by spectrophotometry. Glutathione peroxidase-4 (GPX4), ferroportin (FPN), transferrin receptor (TfR1), and 4-hydroxynonenal (4-HNE)-modified protein levels were assessed by Western blotting. Functional recovery was assessed using Basso-Beattie-Bresnahan test. Results: Silibinin achieved significant suppression in MDA and 4-HNE levels compared to the SCI both in 72-h and 6 weeks group (p < 0.05). GSH, GPX4, and FNP levels were found to be significantly higher in the silibinin 24 h, 72 h, and 6 weeks group compared to corresponding SCI groups (p < 0.05). Significant reduction in iron levels was observed in silibinin treated rats in 72 h and 6 weeks group (p < 0.05). Silibinin substantially suppressed TfR1 levels in 24 h and 72 h groups (p < 0.05). Significant difference among recovery capacities was observed as follows: Silibinin > DFO > SCI (p < 0.05). Conclusion: Impact of silibinin on iron metabolism and lipid peroxidation, both of which are features of ferroptosis, may contribute to therapeutic activity. Within this context, our findings posit silibinin as a potential therapeutic candidate possessing antiferroptotic properties in SCI model. Therapeutic agents capable of effectively and safely mitigating ferroptotic cell death hold the potential to be critical points of future clinical investigations.

RESUMO

BACKGROUND: The aim of this study was to compare the effects of four different immobilization methods [single sugar tong splint (SSTS), double sugar tong splint (DSTS), short arm cast (SAC), and long arm cast (LAC)] commonly used for restricting forearm rotation in the upper extremity. METHODS: Forty healthy volunteers were included in the study. Dominant extremities were used for measurements. Basal pronation and supination of the forearm were measured with a custom-made goniometer, and the total rotation arc was calculated without any immobilization. Next, the measurements were repeated with the SAC, LAC, SSTS and DSTS. Each measurement was compared to the baseline value, and the percentage of rotation restriction was calculated. RESULTS: The most superior restriction rates were observed for the LAC (p = 0.00). No statistically significant difference was detected between the SSTS and DSTS in terms of the restriction of supination, pronation or the rotation arc (p values, 1.00, 0.18, and 0.50, respectively). Statistically significant differences were not detected between the SAC and the SSTS in any of the three parameters (p values, 0.25; 1.00; 1.00, respectively). When the SAC and DSTS were compared, while there was no significant difference between the two methods in pronation (p = 0.50), a statistically significant difference was detected in supination (p = 0.01) and in the total rotation arc (p = 0.03). CONCLUSION: The LAC provides superior results in restricting forearm rotation. The SAC and SSTS had similar effects on forearm rotation. The DSTS, which contains, in addition to the SSTS, a sugar tong portion above the elbow, does not provide additional rotational stability.

RESUMO

INTRODUCTION AND CLINICAL IMPORTANCE: Human scabies is a contagious skin condition caused by the Sarcoptes scabiei mite, leading to skin damage and subsequent mechanical irritation from scratching. This impaired skin integrity predisposes individuals to skin infections. While the association between scabies and skin infections caused by Staphylococcus aureus and Streptococcus pyogenes is well-documented, there is limited literature on the risk of surgical site infections in such cases. CASE PRESENTATION: This case report aims to explore this risk by presenting a case of surgical site infection caused by Streptococcus pyogenes following surgery for a complex elbow injury in a patient with scabies infestation. DISCUSSION: Scabies infestation leads to direct spread of bacteria and contributes to bacterial infection. Furthermore, complement inhibition and dysbiosis induced by the scabies may facilitate the occurrence of these bacterial infections. CONCLUSION: Skin infections are frequently encountered in scabies infestations. Preferred incision should be evaluated meticulously before surgery. Further studies are needed to reach a definitive conclusion on this subject.

RESUMO

INTRODUCTION: Compartment syndrome is an emergency which requires prompt intervention. While main challenge typically revolves around determining necessity for fasciotomy in suspected cases, etiology is often pronounced, leaving little room for differential diagnosis. CASE REPORT: We report a case with unconventional presentation and clinical course, ultimately diagnosed as Munchausen Syndrome. DISCUSSION: It has been reported that individuals with Munchausen syndrome are successful at manipulating healthcare professionals. They often study the symptoms of their sickness, examination findings, and findings that may alert doctors, mastering their techniques over time. CONCLUSION: It is of importance to consider Munchausen Syndrome as a potential cause, particularly in cases where clinical history and course of symptoms do not align with our experiences and cannot be reconciled with other possible diagnostic patterns.

RESUMO

BACKGROUND: Malignancies involving the pelvic ring present numerous challenges, especially in the periacetabular area. Extensive resection of the pelvic region without reconstruction can lead to severe functional impairment. Numerous reconstructive options exist, but all have drawbacks. Extracorporeally irradiated autografts are one option for reconstruction after periacetabular resections; they offer the potential advantages of eliminating the risk of allogeneic reactions associated with allografts and preserving local anatomy. However, little is known about the durability and risks of this approach in pelvic reconstruction. QUESTIONS/PURPOSES: (1) What are the survival rates of the autograft used, and if there is graft loss, what is the extent of this loss? (2) What are the functional outcomes after the implementation of this method? (3) What is the rate and nature of complications associated with this approach? METHODS: This is a retrospective case series from one subspecialty tumor unit that evaluated patients treated between January 2005 to January 2022. During that time, three surgeons treated 48 patients with Type II resections (defined as resection of periacetabular area). Patients treated with isolated Type II resections were eligible, as were those treated either with Type I+II resections, Type II+III resections, Type I+II+III resections, and Type I+II+III+IV resections. Of those, 21% (10 of 48) were treated primarily with a cone prosthesis, 13% (6 of 48) were treated without femoral reconstruction, 10% (5 of 48) were treated with resection without reconstruction, and 6% (3 of 48) had a THA on the sacrum, leaving 50% (24 of 48) of patients who were treated with femoral and acetabular reconstruction using extracorporeally irradiated autograft and total hip replacement; those patients were potentially eligible for this study. During that time span, we used this approach in all Type II pelvic resection procedures, when a part of the hemipelvis could be preserved without resection (other than Type I+II+III+IV) and where we predicted that there would be sufficient bone stock after tumor removal. Of those, 21% (5 of 24) were lost to follow-up before 2 years, and 13% (3 of 24) died within 2 years with the reconstruction intact and without any reoperation or graft loss, leaving 67% (16 of 24) for analysis here. Demographic characteristics, type of tumor, tumor origin site, type of applied resection, and extent of applied surgical procedure were noted. Of 16 patients, 12 were male, with a mean age of 38 ± 21 years. Tumor types included chondrosarcoma in eight patients, malignant mesenchymal tumor in four patients, osteosarcoma in two patients, and Ewing sarcoma in two patients. Among these, 10 patients had tumors originating from the pelvis, whereas six patients had tumors originating from the proximal femur. We used a Kaplan-Meier estimator to calculate survivorship free from total or partial graft removal at 72 months. To measure functional results, the Musculoskeletal Tumor Society (MSTS) scoring system was utilized at most recent follow-up so as to be able to evaluate the impact of complications (if any) on the ultimate result. The MSTS score ranges from a minimum of 0 points to a maximum of 30 points, where a higher score reflects lower pain and higher functional and emotional capacity. Related complications, time of complications, secondary interventions, and mortality rates were also ascertained from chart review. RESULTS: Graft survival rate at 72 months after initial reconstruction, free from partial or total graft removal, was 50% (95% CI 26% to 75%). Kaplan-Meier analyses revealed estimated mean time of graft removal as 43 months (95% CI 28 to 58). The graft was protected in eight patients on their final follow-up radiographs. The median (range) MSTS score was 18 (6 to 25) of 30 points at most-recent follow-up (these scores include patients who have had their grafts removed). In all, 15 of 16 patients had 17 complications; 16 were major complications (defined as those substantial enough to result in further surgery or a life- or limb-threatening event). A total of 14 of those 15 patients underwent one or more secondary procedures (a total of 21 unplanned additional procedures were performed in those patients). Deep infection was the most common complication, occurring in eight patients. Prosthesis dislocation occurred in four patients. Three patients developed aseptic acetabular component loosening, two had graft fractures, and one patient developed heterotopic ossification. CONCLUSION: Composite reconstruction with extracorporeal irradiated autografts plus total hip replacement is a feasible reconstruction technique after Type II pelvic resections, although complications and reoperations were common. Although no reconstruction technique has been proven superior to other alternatives, the high risk of complications and reoperations associated with this technique should be considered when selecting from among possible alternative reconstruction methods. LEVEL OF EVIDENCE: Level IV, therapeutic study.

RESUMO

INTRODUCTION: Knees affected by haemophilic arthropathy exhibit distinct differences in both bone morphology and soft tissue behaviour. This study aims to analyse the morphological characteristics of the distal femur and patellofemoral joint in patients with haemophilia in comparison to normal healthy population. MATERIAL AND METHODS: Study was conducted as pair-matched case-control study with 43 individuals in both the haemophilia group and the control group. Patellar luxation, patellar tilt (PT), length of the patella in both axis (pAP, pML), depth and angle of trochlear sulcus (SD, SA), lateral trochlear inclination (LTI), medial and lateral femoral facet length (mFL, LFL), intercondylar depth (ID), transepicondylar axis (TEA) and lateral condyle length (LCL) were assessed on knee MRI. Correlation between Pettersson score and measured variables were also analysed. RESULTS: PT was medial sided in 10 (23.2%) cases in haemophilic group. Mean values of pAP, pML, PT were significantly lower in haemophilia group (p < .001, p: .007, p = .001 respectively). There were no significant changes in SA (p = .628), SD (p = .340), LTI (p = .685), LFL (p = .241) and MFC-LFC (p = .770) whilst mFL was significantly longer in haemophilia group (p = .009). ID (p < .001), TEA (p = .007) and LCL (p = .001) were all shorter in haemophilia group. Pettersson score was inversely correlated with pAP, pML, ID, TEA, LCL, pML/SA and ID/LCL. CONCLUSION: Morphological changes in haemophilic arthropathy involve a smaller and medially-tilted patella, narrowed lateral condyle and transepicondylar axis, combined with reduced intercondylar depth. These alterations must keep in mind especially in pre- and intraoperative assessments for arthroplasty procedures.

RESUMO

INTRODUCTION: While long bone fractures are commonly seen in individuals with Osteogenesis Imperfecta (OI), femoral neck fractures (FNF) are exceedingly rare. There is a lack of comprehensive data regarding the etiology of FNFs, their characteristics, and the treatment protocols. Our aim was to determine the characteristics of femoral neck fractures in children with OI. MATERIALS AND METHODS: This study was conducted as retrospective series covering period of January 2011-December 2022. Total of 14 femoral neck fractures in 12 patients were included into final analysis. Age, gender, fracture location, ambulation level, injury mechanism, Sillence type, pre-fracture collo-diaphyseal angle, presence of previous implants and applied treatments were noted. RESULTS: The mean age was 9.3 (range: 3-16), 8 out of 12 patients were males. Sillence type 3 OI was most common (50 %) type. Among 12 patients, 2 (16.6 %) were restricted ambulatory while 5 (41.6 %) were non-ambulatory. Seven patients had prior femoral implants. Six fractures were managed non-operatively, while others underwent surgery, with cannulated screws (42.8 %) or plate osteosynthesis (7.1 %). All eight cases (100 %) with minor trauma or unknown origin were Sillence type 3-4, displaying varus deformity. FNFs that occured in mobile patients required higher-energy traumas. CONCLUSION: Femoral neck fractures in OI showed differing trauma mechanisms in ambulatory vs. non-ambulatory patients. Non-surgical treatment may be considered with in patients with high-risk anesthesia concerns, requiring higher level clinical studies.

RESUMO

BACKGROUND: Purpose of this study was to identify factors affecting return to work time and functional outcomes after low-velocity gunshot injuries related to foot. Related complications are also analyzed. METHOD: This study conducted as retrospective cohort study in tertiary care university hospital. Data on 26 patients obtained through retrospective database search. Type of causing weapon, anatomic location of wound, wound type according to Gustilo Anderson classification, extend of damage regarding injured structures, extend of soft tissue damage, duration of hospital stay, need of reconstructive surgery, return-to-work time, follow-up period and functional scores at final follow-up were recorded. Factors affecting functional outcome and return-to-work time were analyzed. RESULTS: Total of 12 patients (46.2 %) experienced complications, with eight being deep soft tissue infections. The mean MFS score for the study group was 77.27 (±11.82). The mean MFS for the pistol group was 83.46 (±6.90), extent of soft tissue damage was an independent risk factor (OR 10.67, 95 % CI 1.70-66.72, p = 0.011) for poor outcomes. On average, patients took 10.12 months (±7.59) to return to work, the type of gun used was an independent variable associated with delayed return to work (OR 144, 95 % CI 8.04-2578.09, p = 0.011). CONCLUSION: Gunshot injuries related to foot can lead to a high rate of complications, loss of workdays, and permanent functional losses. Therefore, it is crucial to develop appropriate treatment plans and manage inevitable complications in these injuries. LEVEL OF EVIDENCE: Level IV, Case series.

RESUMO

INTRODUCTION: Surgical treatment of AO/OTA 43-C pilon fractures has not yet taken a standard form. We aimed to evaluate whether patients that appeared to be labelled as unsupported columns according to the four-column theory would affect long-term clinical and radiological outcomes. MATERIALS AND METHODS: Patients with AO/OTA 43-C type who were treated surgically between January 2010 and December 2019 were included in the study. 53 fractures in 52 patients who received osteosynthesis were categorized based on the fixed columns. These groups were formed as fully supported columns (FSC- Group A), partly supported columns (PSC-Group B), Ankle range of motions (ROM), Burwell Charnley's reduction evaluation criteria, Kellgren-Lawrence ankle osteoarthritis staging system, and American Orthopedic Foot and Ankle Society (AOFAS) Scoring System, Olerud-Molander Ankle Score, Visual Analog Scale were used for evaluating radiological and functional outcomes. RESULTS: The mean follow-up period was 72.6 (12-131) months. Mean age was 42.6 (18-76). Two groups were homogenously distributed in terms of age (p = 0.785), sex (p = 0.376), laterality (p = 0.732), smoking status (p = 0.488) and reduction quality. There was no difference in AOFAS score (p = 0.452), Olerud-Molander score (p = 0.354) and VAS scores (p = 0.589). TAS, TLS and TT angle measurements suggested no difference between groups (p = 0.493, p = 0.834, p = 0.577). There was no difference between groups in terms of infection (p = 0.734), malunion (p = 0.688) and arthritis (p = 0.483) CONCLUSION: We presented findings that contradicted the hypothesis positing the existence of four distinct columns in pilon fractures, as well as the notion that each fractured column requires support from distinct implants. LEVEL OF EVIDENCE: Level III.

RESUMO

OBJECTIVE: In this experimental animal study, a novel bilayered scaffold used in the treatment of osteochondral defects in rabbit knees was evaluated. This novel scaffold's upper (cartilage) layer consists of polyglycolic acid and hyaluronic acid, and the lower (bone) layer consists of ß-tricalcium phosphate. The purpose of this study was to evaluate the efficacy of this novel scaffold, combined with or without mesenchymal stem cells (MSCs), in the treatment of osteochondral defects in rabbit knees. METHODS: Osteochondral defects were created in the left femoral trochlea of 30 rabbits. In group A, defects were treated with scaffold combined with MSCs; in group B, defects were treated with cell-free scaffolds; and group C was a control group with defects left untreated. In the 12th week, animals were sacrificed for macroscopic evaluation. RESULTS: The mean International Cartilage Repair Society (ICRS) macroscopic scores were 4.95 for group A, 6.16 for group B, and 8.25 for group C. The mean Oswestry Arthroscopic Scores (OAS) were 1.65 for group A, 3.39 for group B, and 6.05 for group C. The macroscopic scores were significantly higher in group C than group A for ICRS scores and group A and group B for OAS (P < .001, P < .000, P < .022). CONCLUSION: In essence, our findings indicate that the newly developed osteochondral scaffold, when tested in a rabbit model, is not as effective as expected in repairing full-thickness osteochondral defects, with or without the supplementation of MSCs. Further investigation is required to enhance the effectiveness of this novel combination.

RESUMO

Isolated popliteus injury is a rare clinical condition which can be treated either surgically or conservatively. Factors such as the patient's age, activity level, and cooperation with the medical team are determinants to choose the most optimal treatment option. A 29-year-old female patient presented with a knee injury caused by a low-speed motorcycle accident. Further examination suggested an isolated popliteus injury without any concomitant knee injury. We opted for surgical treatment, as it allowed us to act more confidently in the postoperative follow-up and the patient did not inspire confidence in the medical team in terms of close follow-up and compliance with the physical therapy protocols that would be required, if conservative treatment was chosen. In conclusion, isolated popliteus injury is a rare condition with no consensus on the treatment algorithm. Both surgical and conservative treatments can yield good to excellent results. Surgical treatment may be considered in selected cases where an optimal close follow-up regimen seems to be unlikely.

RESUMO

Osteochondral damage is a commonly encountered issue in the daily orthopedic practice and has been extensively researched across various areas, including tissue transplantations, tissue engineering products, stem cell applications, and cell culture studies. The absence of a universally accepted treatment as the gold standard for osteochondral damage indicates the necessity for further studies in this field in the future. Although the biomechanical characteristics of the rabbit knee do not perfectly mimic those of the human knee, experimental studies conducted on rabbit knees are considered the most practical experimental model for testing a well-constructed experimental hypothesis. Our article endeavors to impart our practical insights and experiences to researchers without experience whom seeking to design studies utilizing this model. We aim to offer valuable guidance for preoperative, operative, and postoperative considerations. •Rabbits used in osteochondral healing models should be at least 4 months old or older. Inducing damage in the trochlea is a well-established technique and relatively easy to apply.•Do not use pointy ended drills as it might create uneven damage. Do not place applied treatment agent in inappropriate level in relation to the surrounding cartilage surface.

INTRODUCTION: Patellar tendon ossification is a rare complication that primarily occurs following a knee injury. This article aims to describe, for the first time, a case of patellar tendon ossification following synovectomy. CASE PRESENTATION: A 48-year-old male with a diagnosis of rheumatoid arthritis presented with swelling in his left knee following a synovectomy procedure. After a thorough physical examination, radiographic assessment, and computed tomography, the patient was diagnosed with total patellar tendon ossification. Subsequently, the patient underwent excision of the ossified mass and tendon reconstruction using an Achilles allograft. DISCUSSION: The primary causes of patellar tendon ossification are iatrogenic and traumatic injuries. The presence of rheumatoid arthritis, which negatively affects tissue healing, may exacerbate this condition. Smaller lesions can be managed conservatively or through resection and repair. In cases of extensive ossification, resection and reconstruction are necessary. A comprehensive literature review is also provided. CONCLUSION: The occurrence of patellar tendon swelling following trauma or surgery should raise suspicion of patellar tendon ossification. Rheumatoid arthritis is a risk factor for the development of patellar tendon ossification. In cases of extensive ossification, successful treatment can be achieved through reconstruction using an Achilles allograft.

RESUMO

Purpose: The purpose of this study is to evaluate the side effects associated with hyperbaric oxygen therapy and provide recommendations to prevent them in patients with diabetic foot ulcers. Introduction: The use of hyperbaric oxygen therapy in the treatment of diabetic foot ulcers remains a contentious issue, and minimizing side effects is critical. While the incidence of side effects related to hyperbaric oxygen (HBO2) therapy is low, it is essential to evaluate cases in a multifaceted and interdisciplinary manner to prevent adverse outcomes. Methods: A retrospective cohort study was conducted over the period of 2018-2020, involving a dataset of 100 patients. The primary objective of the study was to examine the frequency and types of side effects experienced by patients who underwent hyperbaric oxygen therapy (HBO) for diabetic foot ulcers (DFUs). In addition, we analyzed various wound characteristics, characteristics of hospitalizations, the surgical or medical interventions received by patients, and laboratory parameters including CRP levels, total blood count, culture results, HbA1c levels, duration of diabetes, treatment received for diabetes, and antibiotic therapy regimens. Results: The percentage of patients who experienced side effects was as low as 6%, and none of them were critical. The most common side effect was discomfort due to the confined space in the chamber. Conclusion: Appropriate patient selection, combined with a multidisciplinary approach to evaluate eligibility, is crucial to avoid adverse side effects. Patient education and early screening for side effects are also essential. Since various treatment protocols exist for HBO2 therapy, pooled data from different protocols may be misleading. Further studies focused on side effects with specific indications are necessary.

RESUMO

OBJECTIVES: The aim of this study was to compare the results of single sugar-tong splint (SSTS) and long arm cast (LAC) as an immobilization method in pediatric distal forearm fractures. PATIENTS AND METHODS: Between January 2016 and December 2019, a total of 186 pediatric patients (143 males, 43 females; mean age: 10.3±3 years; range, 4 to 15 years) with distal forearm fractures were retrospectively analyzed. The patients were divided into two groups according to the immobilization method: SSTS group (n=74) and LAC group (n=112). All patients were evaluated at the time of admission, immediately after the reduction, and at one, two, and four weeks. Sagittal and coronal plane angulations and translation percentages of the radius at each visit were calculated. Alterations in coronal angle, sagittal angle, sagittal translation and coronal translation were calculated by subtracting the measurements after reduction from the measurements at four weeks. RESULTS: Both groups were comparable in terms of demographic characteristics, fracture localization, and side of injured extremity. There was a statistically significant difference only in the sagittal angulations in the first (LAC: 4.7; SSTS: 6.5; p=0.009) and second week (LAC: 5.3; SSTS: 6.8; p=0.024). The rest of radiological measurements were comparable. In the LAC group, seven patients had re-intervention (three manipulations, four surgeries) and in the SSTS group, three patients had re-intervention (two manipulations, one surgery) (p=0.657). CONCLUSION: Our study results suggest that SSTS and LAC are comparable in terms of radiological results and need for re-intervention as an immobilization method of pediatric distal forearm fractures.

RESUMO

Amputations related to diabetic foot ulcers (DFU) are associated with high morbidity and mortality rates. Glycaemic control and close follow-up protocols are essential to prevent such ulcers. Coronavirus disease (COVID) related restrictions and regulations might have a negative impact on patients who are with DFU or candidates for DFU. We retrospectively analysed 126 cases that had DFU underwent amputation surgery. Comparative analyses were done between cases that were admitted before COVID restrictions (Group A) and cases admitted after COVID restrictions (Group B). Two groups were homogenic demographically. There was no significant difference between groups in terms of mortality (p = 0.239) and amputation rates (p = 0.461). The number of emergent cases in the pandemic period doubled the number in pre-pandemic period even though this finding was not statistically significant (p = 0.112). Fastly adapted consulting practice and follow-up protocols to compensate for the problems created by COVID-related regulations seem to be effective in terms of mortality and amputation rates.

RESUMO

Research on spinal cord injuries is an important and living topic that raises many critical questions that need to be addressed. While numerous articles have compiled and compared various models of spinal cord injuries, there is limited comprehensive guide with clear instructions available for researchers who are unfamiliar with clip compression model. This model creates acute compression damage in spinal cord, which aims to mimic the nature of traumatic spinal cord damage in humans. Purpose of this article is to share our experience on clip compression model, with experience gained from more than 150 animals, and to provide guidance for researchers with lack of experience who wish to design studies with this model. We have defined several key variables, as well as the difficulties that may arise when applying this model.-Proper preparation, good infrastructure and necessary tools and knowledge of anatomy related is essential to the success of this model.-Good exposure with non-bleeding surgical site is key factor for surgical step.-Postoperative care is particularly challenging, and researchers should consider extending their studies over a reasonable time period to ensure that appropriate care could be provided.
