A comprehensive analysis of patients with cerebral arteriovenous malformation with headache: assessment of risk factors and treatment effectiveness.

BACKGROUND: Due to the high mortality and disability rate of intracranial hemorrhage, headache is not the main focus of research on cerebral arteriovenous malformation (AVM), so research on headaches in AVM is still scarce, and the clinical understanding is shallow. This study aims to delineate the risk factors associated with headaches in AVM and to compare the effectiveness of various intervention treatments versus conservative treatment in alleviating headache symptoms. METHODS: This study conducted a retrospective analysis of AVMs who were treated in our institution from August 2011 to December 2021. Multivariable logistic regression analysis was employed to assess the risk factors for headaches in AVMs with unruptured, non-epileptic. Additionally, the effectiveness of different intervention treatments compared to conservative management in alleviating headaches was evaluated through propensity score matching (PSM). RESULTS: A total of 946 patients were included in the analysis of risk factors for headaches. Multivariate logistic regression analysis identified that female (OR 1.532, 95% CI 1.173-2.001, p = 0.002), supply artery dilatation (OR 1.423, 95% CI 1.082-1.872, p = 0.012), and occipital lobe (OR 1.785, 95% CI 1.307-2.439, p < 0.001) as independent risk factors for the occurrence of headaches. There were 443 AVMs with headache symptoms. After propensity score matching, the microsurgery group (OR 7.27, 95% CI 2.82-18.7 p < 0.001), stereotactic radiosurgery group(OR 9.46, 95% CI 2.26-39.6, p = 0.002), and multimodality treatment group (OR 8.34 95% CI 2.87-24.3, p < 0.001) demonstrate significant headache relief compared to the conservative group. However, there was no significant difference between the embolization group (OR 2.24 95% CI 0.88-5.69, p = 0.091) and the conservative group. CONCLUSIONS: This study identified potential risk factors for headaches in AVMs and found that microsurgery, stereotactic radiosurgery, and multimodal therapy had significant benefits in headache relief compared to conservative treatment. These findings provide important guidance for clinicians when developing treatment options that can help improve overall treatment outcomes and quality of life for patients.

Conservative Management of Large Post-Intubation Tracheal Laceration.

ABSTRACT: Tracheal rupture is a very rare but life-threatening complication of endotracheal intubation. It is more common in women and patients older than 50 years old. Overinflation of endotracheal tube cuff and tracheal wall weakening are the most important pathogenetic mechanisms. Laceration sites are located in the posterior membranous wall in most cases. Subcutaneous and mediastinal emphysema and respiratory distress are the most common manifestations. A 55-year-old female presented with postoperative subcutaneous and mediastinal emphysema without dyspnea because of a tear in the posterior tracheal wall. The diagnosis was based on clinical manifestation, chest computer tomography scans (CT), and endoscopic findings. A conservative approach by broad-spectrum antibiotic therapy was decided because of patients' vital signs stability and the absence of esophageal injury. The follow-up showed that there was no lesion in the posterior tracheal wall. Our case showed that in clinically stable patients without mediastinitis and with spontaneous breathing, conservative management of tracheal tears is a safe procedure.

Conservative treatment of Peyronie's disease: a guide.

PURPOSE: To review the literature on the topic, to suggest a common line of treatment applicable across a wide community of specialists, and to contribute in maintaining the high level of interest in this disease. METHODS: A comprehensive and exhaustive review of the literature was performed, identifying hundreds of articles on the topic. RESULTS: Peyronie's disease is a condition that has been recognized, studied, and treated for centuries; despite this, if one excludes surgery in cases in which the deformity is stable, no clear treatment (or line of treatment) is available for complete relief of signs and symptoms. Treatment options were divided into local, oral, and injection therapy, and a wide variety of drugs, remedies, and options were identified. CONCLUSIONS: Low-intensity extracorporeal shock wave therapy, vacuum therapy, penile traction therapy, phosphodiesterase type 5 inhibitors, hyaluronic acid, and collagenase of Clostridium histolyticum may be recommended only in specific contexts. Further studies on individual options or potential combinations are required.

Conservative treatment of congenital radial head subluxation and non-traumatic elbow locking: A case report.

Congenital radial head subluxation is relatively rare and may be overlooked due to mild symptoms. The diagnosis mainly relies on imaging and history. Observation is an option for those with insignificant symptoms, while surgical intervention, such as ulnar osteotomy or arthroscopy, is often required when dysfunction exists. A 30-year-old man was admitted with congenital radial head dislocation, which was treated with manipulative repositioning. During follow-up, the patient regained the original mobility of the elbow joint and had no recurrence of dislocation. In conclusion, in adults with congenital dislocation of the radial head, we recommend conservative treatment as a first step.

Assessment of Radiation Induced Pneumonitis and Pericarditis in Patients Undergoing Breast Conservative Treatment Using Hypofractionated Simultaneous Integrated Boost Technique.

INTRODUCTION: To determine the proportion of radiationinduced pneumonitis and pericarditis in patients who have received Hypo-fractionated Radiation along with simultaneous integrated boost technique after breast conservative surgery using a prospective observational study from a tertiary hospital. MATERIALS & METHODS: The incidence of radiationinduced pneumonitis and pericarditis was evaluated in all adult patients with biopsy-proven early-stage unilateral breast cancer who underwent breast-conserving surgery followed by hypo-fractionated radiation with a simultaneous integrated boost technique. Baseline assessments including a six-minute walk test, highresolution computed tomography (HRCT), pulmonary function tests (PFTs), electrocardiography (ECG) and echocardiography (ECHO) were performed. At three months post-radiation treatment, patients underwent follow-up assessments with a six-minute walk test, ECG and ECHO. At six months post-radiation treatment, patients underwent further assessments with a six-minute walk test, ECG, ECHO, PFTs, and HRCT of the thorax. Data analysis was performed using SPSS version 19. RESULTS: Our study investigated the incidence of acute radiation-induced pneumonitis and pericarditis in patients treated with hypofractionated VMAT-SIB technique in 20 eligible early breast cancer patients. The study found that the technique is feasible and achieves encouraging dosimetric parameters, including well achieved ipsilateral lung and heart doses. The reduced treatment time of 3-4 weeks compared to the previous 6-7 weeks with sequential boost was also found to be desirable in resource-constrained settings. The incidence of acute radiation pneumonitis and pericarditis was acceptable and comparable to existing data, with 90% of patients experiencing grade 1 radiation pneumonitis according to CTCAE v5.0. Post-treatment pulmonary function tests showed significant changes, particularly in patients who had received neoadjuvant chemotherapy and nodal irradiation. The six-minute walk test and Borg scale also showed a significant positive correlation with pulmonary function tests. There was no significant pericarditis during the follow-up. The study proposes that the hypofractionated radiotherapy using VMAT-SIB is a suitable alternative to conventional fractionation, with acceptable acute toxicities, but longer follow-up is required to assess the impact on late toxicities. CONCLUSION: Our research has shown that hypofractionated adjuvant radiotherapy with SIB is a safe and feasible treatment for patients with early breast cancer. This treatment method doesn't pose any significant short-term risks to the lungs or heart, and the SIB technique provides better coverage, conformity and sparing of organs at risk. Additionally, patients have reported positive cosmetic outcomes with this treatment. However, to make more accurate conclusions, we need to conduct further studies with larger sample sizes and longer follow-up periods to evaluate the potential longterm side effects of this treatment using VMAT in whole breast radiation.

Synovial fluid monocyte-to-lymphocyte ratio in knee osteoarthritis patients predicts patient response to conservative treatment: a retrospective cohort study.

BACKGROUND: Biomarkers that predict the treatment response in patients with knee osteoarthritis are scarce. This study aimed to investigate the potential role of synovial fluid cell counts and their ratios as biomarkers of primary knee osteoarthritis. METHODS: This retrospective study investigated 96 consecutive knee osteoarthritis patients with knee effusion who underwent joint fluid aspiration analysis and received concomitant intra-articular corticosteroid injections and blood tests. The monocyte-to-lymphocyte ratio (MLR) and neutrophil-to-lymphocyte ratio (NLR) were calculated. After 6 months of treatment, patients were divided into two groups: the responder group showing symptom resolution, defined by a visual analog scale (VAS) score of ≤ 3, without additional treatment, and the non-responder group showing residual symptoms, defined by a VAS score of > 3 and requiring further intervention, such as additional medication, repeated injections, or surgical treatment. Unpaired t-tests and univariate and multivariate logistic regression analyses were conducted between the two groups to predict treatment response after conservative treatment. The predictive value was calculated using the area under the receiver operating characteristic curve, and the optimal cutoff value was determined. RESULTS: Synovial fluid MLR was significantly higher in the non-responder group compared to the responder group (1.86 ± 1.64 vs. 1.11 ± 1.37, respectively; p = 0.02). After accounting for confounding variables, odds ratio of non-responder due to increased MLR were 1.63 (95% confidence interval: 1.11-2.39). The optimal MLR cutoff value for predicting patient response to conservative treatment was 0.941. CONCLUSIONS: MLR may be a potential biomarker for predicting the response to conservative treatment in patients with primary knee osteoarthritis.

Self-inflicted very-low-velocity penetrating head injury: A CARE-compliant case report.

RATIONALE: Low-velocity penetrating head injury (PHI) is rare, comprising 0.2% to 0.4% of head traumas, but can be devastating and is associated with significant morbidity and mortality. No previous case of very-low-velocity PHI due to self-inflicted stabbing with a gimlet has been reported. PATIENT CONCERNS: A 62-year-old man was admitted to the hospital with bleeding head and abdominal wounds after stabbing his abdomen with a gimlet, and then hammering the same gimlet into his forehead and removing the gimlet himself. DIAGNOSES: Upon examination at admission, stab wounds were present on the forehead and the right upper quadrant. Computed tomography (CT) of the head revealed a bone defect in the left frontal bone and showed the intracranial path of the gimlet surrounded by mild hemorrhage and pneumocephalus. Magnetic resonance imaging (MRI) confirmed a small amount of hemorrhage with pneumocephalus but no vascular injury. INTERVENTIONS: Conservative treatment without surgery. OUTCOMES: Follow-up MRI on hospital day 58 showed no abscess or traumatic intracranial aneurysm. The patient achieved full recovery of motor and mental functions with conservative treatment and was discharged on hospital day 69. LESSONS: Very-low-velocity PHI might be successfully treated with conservative treatment.

Early range of motion results in good elbow function following conservative treatment of non-displaced radial head fractures.

INTRODUCTION: The aim of this study was to evaluate the range of motion (ROM), elbow function and predictors for good elbow function after conservative treatment of non-displaced radial head fractures. MATERIAL AND METHODS: All patients with non-displaced radial head fractures (displacement < 2 mm), that were diagnosed between January 1st 2017 and December 31st 2021 in a level I trauma center, were included in this retrospective case series and the charts were evaluated for ROM and elbow function. Elbow function was categorized as "good" or "bad" depending on the ROM measured defined by Morrey et al. Overall, 73 patients (33 male, 40 female) with an average age of 38 years (+/- 13 years) could be included. RESULTS: Conservative treatment had good clinical results for ROM and elbow function. After 6 weeks mean flexion was 131° (SD 13°), extension 8° (SD 7°), Pronation 83° (SD 11°) and Supination 83° (SD 13). Patients with a good elbow function after one week showed a good elbow function after completing the treatment. CONCLUSIONS: A clinical assessment after one week should always be performed and the study showed that it is a good predictor for good elbow function. In cases of bad elbow function further controls should be considered.

Acute diverticulitis with extraluminal air: is conservative treatment sufficient? A single-center retrospective study.

BACKGROUND: Acute diverticulitis with extraluminal air constitutes a heterogeneous condition whose management is controversial. The aims of this study are to report the failure rate of conservative treatment for diverticulitis with extraluminal air and to report risk factors of conservative treatment failure. METHODS: A retrospective study was performed from an institutional review board-approved database of patients admitted with acute diverticulitis with extraluminal air from 2015 to 2021 at a tertiary referral center. All patients managed for acute diverticulitis with covered perforation (without intraabdominal abscess) were included. The primary endpoint was failure of medical treatment, defined as a need for unplanned surgery or percutaneous drainage within 30 days after admission. RESULTS: Ninety-three patients (61% male, mean age 57 ± 17 years) were retrospectively included. Ten patients had failure of conservative treatment (11%). These patients were significantly older than 50 years (n = 9/10, 90% versus n = 47/83, 57%, p = 0.007), associated with cardiovascular disease (n = 6/10, 60% versus n = 10/83, 12%, p = 0.002), American Society of Anesthesiologists (ASA) score of 3-4 (n = 4/7, 57% versus 6/33, 18%, p = 0.05), under anticoagulant and antiplatelet (n = 6/10, 60% versus n = 11/83, 13%, p = 0.04) and steroid or immunosuppressive therapy (n = 3/10, 30% versus 5/83, 6%, p = 0.04), and with distant pneumoperitoneum location (n = 7/10, 70% versus n = 14/83, 17%, p = 0.001) compared with those with successful conservative treatment. On multivariate analysis, only distant pneumoperitoneum was an independent risk factor of failure (odds ratio (OR) 6.5, 95% confidence interval (CI) [2-21], p = 0.002). CONCLUSIONS: Conservative treatment with antibiotics for acute diverticulitis with extraluminal air is safe with a success rate of 89%. Patients with distant pneumoperitoneum should be carefully monitored.

Clinical outcomes of conservative versus surgical treatment for patients with proximal humeral fracture before physiotherapy.

Fear of movement, pain, and loss of shoulder function are the most common problems irrespective of their approach to management after proximal humeral fracture (PHF). However, it has been unclear whether there could be differences between both treatments in early clinical outcomes. It can help physiotherapists to guide in choosing treatment approaches. This study aimed to compare kinesiophobia, pain, range of motion (ROM), shoulder function, and Quality of life (QoL) in patients treated with either conservative (CT) versus surgical (ST) after PHF. In addition, it aimed to determine correlations between fear of movement and seconder outcome measures. This cross-sectional study enrolled the patients having 5-6 weeks (being permitted active movement) after being treated either CT or ST and receiving no physical therapy. Pain, passive and active ROMs, shoulder function, fear of movement, and QoL were evaluated. 42 patients were recruited. Kinesiophobia scores were similar (p=0.55) and moderate in both groups. There was a significant difference in degrees of shoulder active flexion, active and passive abduction in favor of the CT group (p=0.05, p=0.02, p=0.04, respectively). However, there was no difference between groups regarding the remaining clinical outcomes. Furthermore, kinesiophobia showed a moderate negative correlation with energy/fatigue, social functioning, and general health. These findings showed that patients treated surgically did not have more kinesiophobia, less function, and QoL before starting physiotherapy, despite having soft tissue damage and different types of fractures. However, surgically treated patients had significantly less range of motion.

Switches in non-invasive respiratory support strategies during acute hypoxemic respiratory failure: Need to monitoring from a retrospective observational study

Objective To explore combined non-invasive-respiratory-support (NIRS) patterns, reasons for NIRS switching, and their potential impact on clinical outcomes in acute-hypoxemic-respiratory-failure (AHRF) patients. Design Retrospective, single-center observational study. Setting Intensive Care Medicine. Patients AHRF patients (cardiac origin and respiratory acidosis excluded) underwent combined NIRS therapies such as non-invasive-ventilation (NIV) and High-Flow-Nasal-Cannula (HFNC). Interventions Patients were classified based on the first NIRS switch performed (HFNC-to-NIV or NIV-to-HFNC), and further specific NIRS switching strategies (NIV trial-like vs. Non-NIV trial-like and single vs. multiples switches) were independently evaluated. Main variables of interest Reasons for switching, NIRS failure and mortality rates. Results A total of 63 patients with AHRF were included, receiving combined NIRS, 58.7% classified in the HFNC-to-NIV group and 41.3% in the NIV-to-HFNC group. Reason for switching from HFNC to NIV was AHRF worsening (100%), while from NIV to HFNC was respiratory improvement (76.9%). NIRS failure rates were higher in the HFNC-to-NIV than in NIV-to-HFNC group (81% vs. 35%, p < 0.001). Among HFNC-to-NIV patients, there was no difference in the failure rate between the NIV trial-like and non-NIV trial-like groups (86% vs. 78%, p = 0.575) but the mortality rate was significantly lower in NIV trial-like group (14% vs. 52%, p = 0.02). Among NIV to HFNC patients, NIV failure was lower in the single switch group compared to the multiple switches group (15% vs. 53%, p = 0.039), with a shorter length of stay (5 [2–8] vs. 12 [8–30] days, p = 0.001). Conclusions NIRS combination is used in real life and both switches’ strategies, HFNC to NIV and NIV to HFNC, are common in AHRF management. Transitioning from HFNC to NIV is suggested as a therapeutic escalation and in this context performance of a NIV-trial could be beneficial. ... (AU)

Objetivo Explorar los patrones combinados de soporte-respiratorio-no-invasivo (SRNI), las razones para cambiar de SRNI y su potencial impacto en los resultados clínicos en pacientes con insuficiencia-respiratoria-aguda-hipoxémica (IRAH). Diseño Estudio observacional retrospectivo unicéntrico. Ámbito Cuidados Intensivos. Pacientes Pacientes con IRAH (excluyendo causa cardíaca y acidosis respiratoria) que recibieron tanto ventilación-no-invasiva (VNI) como cánula-nasal-de-alto-flujo (CNAF). Intervenciones Se categorizó a los pacientes según el primer cambio de SRNI realizado (CNAF-to-VNI o VNI-to-CNAF) y se evaluaron estrategias específicas de SRNI (VNI trial-like vs. Non-VNI trial-like y cambio único vs. múltiples cambios de NIRS) de manera independiente. Variables de interés principales Razones para el cambio, así como las tasas de fracaso de SRNI y la mortalidad. Resultados Un total de 63 pacientes recibieron SRNI combinado, 58,7% clasificados en el grupo CNAF-to-VNI y 41,3% en el grupo VNI-to-CNAF. Los cambios de CNAF a VNI ocurrieron por empeoramiento de la IRHA (100%) y de VNI a CNAF por mejora respiratoria (76.9%). Las tasas de fracaso de SRNI fueron mayores de CNAF a VNI que de VNI a CNAF (81% vs. 35%, p < 0.001). Dentro de los pacientes de CNAF a VNI, no hubo diferencia en las tasas de fracaso entre los grupos VNI trial-like y no-VNI trial-like (86% vs. 78%, p = 0.575), pero la mortalidad fue menor en el grupo VNI trial-like (14% vs. 52%, p = 0.02). Dentro de los pacientes de VNI a CNAF, el fracaso de VNI fue menor en grupo de cambio único vs. múltiple (15% vs. 53%, p = 0.039). Conclusiones Los cambios de estrategia de SRNI son comunes en el manejo clínico diario de la IRHA. El cambio de CNAF a VNI impresiona de ser una escalada terapéutica y en este contexto la realización de un VNI-trial puede ser beneficioso. Al contrario, cambiar de VNI a CNAF impresiona de ser una desescalada terapéutica y parece segura si no hay fracaso ... (AU)

Spinal degeneration and lumbar multifidus muscle quality may independently affect clinical outcomes in patients conservatively managed for low back or leg pain.

Few non-surgical, longitudinal studies have evaluated the relations between spinal degeneration, lumbar multifidus muscle (LMM) quality, and clinical outcomes. None have assessed the potential mediating role of the LMM between degenerative pathology and 12-month clinical outcomes. This prospective cohort study used baseline and 12-month follow-up data from 569 patients conservatively managed for low back or back-related leg pain to estimate the effects of aggregate degenerative lumbar MRI findings and LMM quality on 12-month low back and leg pain intensity (0-10) and disability (0-23) outcomes, and explored the mediating role of LMM quality between degenerative findings and 12-month clinical outcomes. Adjusted mixed effects generalized linear models separately estimated the effect of aggregate spinal pathology and LMM quality. Mediation models estimated the direct and indirect effects of pathology on leg pain, and pathology and LMM quality on leg pain, respectively. Multivariable analysis identified a leg pain rating change of 0.99 [0.14; 1.84] (unstandardized beta coefficients [95% CI]) in the presence of ≥ 4 pathologies, and a disability rating change of - 0.65 [- 0.14; - 1.16] for each 10% increase in muscle quality, but no effect on back pain intensity. Muscle quality had a non-significant mediating role (13.4%) between pathology and leg pain intensity. The number of different pathologies present demonstrated a small effect on 12-month leg pain intensity outcomes, while higher LMM quality had a direct effect on 12-month disability ratings but no mediating effect between pathology and leg pain. The relations between degenerative pathology, LMM quality, and pain-related outcomes appear complex and may include independent pathways.

Conservative management for pediatric craniocervical Pott's disease: A case study and literature review.

Craniocervical Pott's disease is rare, particularly in the pediatric population. The importance of motion preservation in this age group renders managing this disease even more challenging. The literature regarding craniocervical Pott's disease comes from endemic regions. Most authors will agree on early surgical intervention in cases of neurological compromise or severe instability, while patients with minimal symptoms will do well with conservative management. Controversy remains when patients are mildly symptomatic but with imaging findings concerning for significant instability. Here, we present the case of a 15-year-old male presenting with craniocervical tuberculoma with radiographic instability and advanced bony destruction without overt neurological deficits. He was managed with a rigid cervical collar and completed 1 year of anti-tuberculosis therapy. At 1-year follow-up, he had an intact range of motion, was pain-free, and remained neurologically intact. Although this case suggests good outcomes with conservative management are possible, more long-term follow-up is required to assess the need for delayed surgical intervention in this unique population.

Conservative treatment of 3- and 4-part proximal humeral fractures: Can poor outcomes be predicted?

PURPOSE: 3- and 4-part proximal humeral fractures are frequently treated conservatively. This study aims to combine radiographic, and patient reported outcome data to identify factors leading to poor outcomes following conservative treatment. METHODS: A retrospective local database analysis identified 3- and 4-part fractures. Radiographic and functional outcomes including Oxford Shoulder Score (OSS), QuickDash (QD), Subjective Shoulder Score (SSV) and VAS pain scores were collected. RESULTS: 104 patients were included at mean follow-up of 55 months. Analysis highlighted significant OSS differences in 3- versus 4-part (p = 0.027), dominant arm injury (p = 0.046), age > 65 (p = 0.006), varus coronal neck-shaft angle < 115 versus 115-155 degrees (p = 0.008), posterior head tilt > 155 degrees (p = 0.005), greater tuberosity (GT) displacement > 5 mm (p = 0.001), GT comminution (p = 0.01), medial calcar hinge displacement > 2 mm (p = 0.032). According to QD scores; age > 65 (p = 0.012), varus neck-shaft angle (p = 0.01), GT displacement > 5 mm (p = 0.001), GT comminution (p = 0.01), medial calcar hinge displacement > 2 mm (p = 0.006). SSV varied significantly with 3- versus 4-part fractures (p = 0.005), age > 65 (p = 0.04), varus neck-shaft angle (p = 0.001), posterior head tilt (p = 0.005), GT displacement > 5 mm (p = 0.001), GT comminution (p = 0.003), and medial calcar hinge displacement > 2 mm (p = 0.001). CONCLUSION: We highlight risk factors for unfavourable outcomes following conservative management, aiding surgeons in shared decision-making and patient expectation management.

[Conservative treatment of valvular heart disease in adults]. / Konservative Therapie von Herzklappenvitien im Erwachsenenalter.

Currently, there is no specific medication approved for the treatment of valvular heart disease per se. Except for secondary mitral valve insufficiency and tricuspid valve insufficiency in pulmonary hypertension, drug therapy for higher-grade valvular heart disease is limited to diuretic therapy for symptom control. Conservative therapy for comorbidities and potential heart failure can be beneficial regardless of the specific valve lesion. In cases of aortic valve stenosis or insufficiency, controlling arterial hypertension is important. Patients with mitral valve stenosis benefit from rhythm and rate control. Diuretics can help reduce regurgitant volume in patients with primary mitral valve insufficiency and tricuspid valve insufficiency. In addition to drug therapy, maintaining functional capacity is crucial for the outcome of patients. Therefore, it is recommended to engage in active physical activity whenever possible, despite the presence of valvular heart disease.

No Differences in Clinical, Functional, or Patient-Reported Outcomes Following Trial of Nonoperative Management Before Open Reduction and Internal Fixation of Humeral Shaft Fractures.

OBJECTIVES: To test the hypothesis that primary osteosynthesis of humeral shaft fractures may lead to more favorable clinical, functional, and patient-reported outcomes than fixation following a trial of nonoperative management. DESIGN: Retrospective cohort review. SETTING: Academic level I trauma center. PATIENT SELECTION CRITERIA: Adult patients who presented with humeral shaft fractures and ultimately underwent open reduction and internal fixation (ORIF) from May 2011 to May 2021. Patients who underwent ORIF within 2 weeks of injury were grouped into the primary osteosynthesis cohort, and patients who underwent ORIF >4 weeks from the date of injury were grouped into the trial of nonoperative cohort. OUTCOME MEASURES AND COMPARISONS: Postoperative complications, elbow arc of motion, time to radiographic union, and patient-reported outcomes were investigated and compared between the primary osteosynthesis and trial of nonoperative management cohorts. RESULTS: One hundred twenty-seven patients fit the study criteria, 84 underwent primary osteosynthesis and 43 trialed initial nonoperative treatment. No differences were found in patient demographics between the primary osteosynthesis and trial of nonoperative management cohorts, including age (53 ± 19 vs. 57 ± 18; P = 0.25), sex (39% vs. 44% male, 61% vs. 56% female; P = 0.70), and Body Mass Index (BMI) (30 ± 6 vs. 32 ± 9; P = 0.38). The average time to operative intervention in the primary osteosynthesis group was 4 days (0-14 days) and 105 days (28-332 days) in the trial of nonoperative treatment group ( P < 0.01). No differences were found with regard to intraoperative blood loss, total operative time, time to radiographic union (determined using the Radiographic Union Scores for Humeral scoring system), or overall complication rates, including primary and secondary radial nerve injuries ( P = 0.23 and 0.86, respectively). Patients reported similar patient-reported outcomes measurement information system pain interference ( P = 0.73), depression (D) ( P = 0.99), and physical function ( P = 0.66) scores at their 6-month postsurgical follow-up visits. CONCLUSIONS: Patients who attempted a trial of nonoperative management for humeral shaft fractures before ORIF had similar clinical, functional, and patient-reported outcomes as those who underwent primary osteosynthesis. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Improved Short-Term Prognosis of Pediatric Partial-Thickness Burns: Emergency Conservative Debridement Under Topical Anesthesia.

OBJECTIVES: Early wound management for pediatric patients with partial-thickness burns in the emergency department remains debatable. This study aims to evaluate the value of emergency conservative debridement under topical anesthesia in improving short-term prognosis of pediatric partial-thickness burns. METHODS: This retrospective cohort study enrolled children with partial-thickness thermal burns presenting to the emergency department within 6 hours postburn. All the enrolled patients were divided into 2 groups: the debridement group and the dressing group. The associations between emergency conservative debridement and time to reepithelialization was analyzed by using Kaplan-Meier curves with log rank test and multivariate Cox regression analysis. Moreover, the associations between emergency conservative debridement and in-hospital cost and length of stay were also evaluated. RESULTS: All baseline characteristics between groups were comparable (all P > 0.05). Emergency conservative debridement under topical anesthesia significantly decreased the median value of time to reepithelialization (13 vs 14 days, P = 0.02). Cox regression analysis showed that emergency conservative debridement significantly improved wound reepithelialization after adjusting for burn size (odds ratio, 4.07; 95% confidence interval, 1.64-10.11; P < 0.01). The mean length of stay of patients receiving conservative wound debridement was lower than that of patients in the wound dressing group (14.3 ± 7.3 vs 18.8 ± 10.4 days, P < 0.01), but not in terms of mean in-hospital cost per 1% total body surface area (2.8 ± 1.9 vs 3.0 ± 2.1 × 103 RMB per 1% total body surface area, P = 0.58). CONCLUSIONS: Emergency conservative debridement of pediatric partial-thickness burns under topical anesthesia significantly improves the wound healing outcomes without increasing health care burden.
