Refracture following vertebral fragility fracture when bone fragility is not recognized: summarizing findings from comparator arms of randomized clinical trials.

PURPOSE: Since vertebral fragility fractures (VFFs) might increase the risk of subsequent fractures, we evaluated the incidence rate and the refracture risk of subsequent vertebral and non-vertebral fragility fractures (nVFFs) in untreated patients with a previous VFF. METHODS: We systematically searched PubMed, Embase, and Cochrane Library up to February 2022 for randomized clinical trials (RCTs) that analyzed the occurrence of subsequent fractures in untreated patients with prior VFFs. Two authors independently extracted data and appraised the risk of bias in the selected studies. Primary outcomes were subsequent VFFs, while secondary outcomes were further nVFFs. The outcome of refracture within ≥ 2 years after the index fracture was measured as (i) rate, expressed per 100 person-years (PYs), and (ii) risk, expressed in percentage. RESULTS: Forty RCTs met our inclusion criteria, ranging from medium to high quality. Among untreated patients with prior VFFs, the rate of subsequent VFFs and nVFFs was 12 [95% confidence interval (CI) 9-16] and 6 (95% CI 5-8%) per 100 PYs, respectively. The higher the number of previous VFFs, the higher the incidence. Moreover, the risk of VFFs and nVFFs increased within 2 (16.6% and 8%) and 4 years (35.1% and 17.4%) based on the index VFF. CONCLUSION: The highest risk of subsequent VFFs or nVFFs was already detected within 2 years following the initial VFF. Thus, prompt interventions should be designed to improve the detection and treatment of VFFs, aiming to reduce the risk of future FFs and properly implement secondary preventive measures.

A systematic review on the performance of fracture risk assessment tools: FRAX, DeFRA, FRA-HS.

PURPOSE: Preventing fragility fractures by treating osteoporosis may reduce disability and mortality worldwide. Algorithms combining clinical risk factors with bone mineral density have been developed to better estimate fracture risk and possible treatment thresholds. This systematic review supported panel members of the Italian Fragility Fracture Guidelines in recommending the use of best-performant tool. The clinical performance of the three most used fracture risk assessment tools (DeFRA, FRAX, and FRA-HS) was assessed in at-risk patients. METHODS: PubMed, Embase, and Cochrane Library were searched till December 2020 for studies investigating risk assessment tools for predicting major osteoporotic or hip fractures in patients with osteoporosis or fragility fractures. Sensitivity (Sn), specificity (Sp), and areas under the curve (AUCs) were evaluated for all tools at different thresholds. Quality assessment was performed using the Quality Assessment of Diagnostic Accuracy Studies-2; certainty of evidence (CoE) was evaluated using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: Forty-three articles were considered (40, 1, and 2 for FRAX, FRA-HS, and DeFRA, respectively), with the CoE ranging from very low to high quality. A reduction of Sn and increase of Sp for major osteoporotic fractures were observed among women and the entire population with cut-off augmentation. No significant differences were found on comparing FRAX to DeFRA in women (AUC 59-88% vs. 74%) and diabetics (AUC 73% vs. 89%). FRAX demonstrated non-significantly better discriminatory power than FRA-HS among men. CONCLUSION: The task force formulated appropriate recommendations on the use of any fracture risk assessment tools in patients with or at risk of fragility fractures, since no statistically significant differences emerged across different prediction tools.

The integrated structure of care: evidence for the efficacy of models of clinical governance in the prevention of fragility fractures after recent sentinel fracture after the age of 50 years.

Randomized clinical trials and observational studies on the implementation of clinical governance models, in patients who had experienced a fragility fracture, were examined. Literature was systematically reviewed and summarized by a panel of experts who formulated recommendations for the Italian guideline. PURPOSE: After experiencing a fracture, several strategies may be adopted to reduce the risk of recurrent fragility fractures and associated morbidity and mortality. Clinical governance models, such as the fracture liaison service (FLS), have been introduced for the identification, treatment, and monitoring of patients with secondary fragility fractures. A systematic review was conducted to evaluate the association between multidisciplinary care systems and several outcomes in patients with a fragility fracture in the context of the development of the Italian Guidelines. METHODS: PubMed, Embase, and the Cochrane Library were investigated up to December 2020 to update the search of the Scottish Intercollegiate Guidelines Network. Randomized clinical trials (RCTs) and observational studies that analyzed clinical governance models in patients who had experienced a fragility fracture were eligible. Three authors independently extracted data and appraised the risk of bias in the included studies. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation methodology. Effect sizes were pooled in a meta-analysis using random-effects models. Primary outcomes were bone mineral density values, antiosteoporotic therapy initiation, adherence to antiosteoporotic medications, subsequent fracture, and mortality risk, while secondary outcomes were quality of life and physical performance. RESULTS: Fifteen RCTs and 62 observational studies, ranging from very low to low quality for bone mineral density values, antiosteoporotic initiation, adherence to antiosteoporotic medications, subsequent fracture, mortality, met our inclusion criteria. The implementation of clinical governance models compared to their pre-implementation or standard care/non-attenders significantly improved BMD testing rate, and increased the number of patients who initiated antiosteoporotic therapy and enhanced their adherence to the medications. Moreover, the treatment by clinical governance model respect to standard care/non-attenders significantly reduced the risk of subsequent fracture and mortality. The integrated structure of care enhanced the quality of life and physical function among patients with fragility fractures. CONCLUSIONS: Based on our findings, clinicians should promote the management of patients experiencing a fragility fracture through structured and integrated models of care. The task force has formulated appropriate recommendations on the implementation of multidisciplinary care systems in patients with, or at risk of, fragility fractures.

Outcome and cost at a children's hospital following resuscitation for out-of-hospital cardiopulmonary arrest.

OBJECTIVE: To determine the outcome and cost for children resuscitated following out-of-hospital cardiopulmonary arrest. DESIGN: Retrospective case series. SETTING: An organized prehospital emergency medical system within Birmingham, Ala, in a county with 150,493 children under the age of 15 years. PATIENTS: Sixty-three pediatric victims of out-of-hospital cardiopulmonary arrest of any cause presenting to the emergency department of a children's hospital. INTERVENTION: Standard resuscitative techniques were performed for all patients until resuscitative efforts were discontinued in the hospital emergency department or successful resuscitation was achieved. MAIN OUTCOME MEASURES: Successful resuscitation, survival to hospital discharge, neurological outcome, final disposition, and cost of hospital care. RESULTS: Of 63 children with out-of-hospital cardiopulmonary arrest treated in the emergency department of a children's hospital, 60 were pulseless and apneic on arrival, 18 (28.6%) were successfully resuscitated and admitted to the intensive care unit, and six (9.5%) were discharged from the hospital. Five of the survivors had severe neurological deficits and one appeared normal. On follow-up, two patients had died (1 month and 7 months after discharge), three were in a vegetative state, and one was normal. The normal patient had successful defibrillation prior to arrival at the emergency department. The average inpatient charge was $10,667 per patient for those who died and $100,000 for those discharged. CONCLUSIONS: Aggressive treatment does not lead to intact survival for victims of out-of-hospital cardiopulmonary arrest who present to the pediatric emergency department with a preterminal rhythm and absence of spontaneous circulation. Resuscitation efforts in the emergency department are commonly successful but lead to death or severe neurological sequelae at discharge with extremely high cost of care.

[Acute epiglottitis]. / Epiglotitis aguda.

Acute epiglottitis caused by Haemophilus influenzae type B (Hib) is seldom described in Chile. To reinforce the need to take this severe entity into account in the differential diagnosis of acute upper respiratory tract obstructions, the case of a 9 month old girl is described, who's symptoms were initially attributed to acute laryngitis, but showed not response to racemic epinephrine and betamethasone therapy. The correct diagnosis of acute epiglottitis was suggested five hours after admission by lateral neck's radiographs and confirmed by direct laryngoscopic examination under general anesthesia. Appropriate treatment was soon instituted including tracheal intubation respiratory support and antibiotics. An uneventful clinical course proceeded from then on. Hemophilus influenzae B was isolated from blood cultures.

[Multidisciplinary management of malignant hepatic tumors in children: a recent national experience]. / Manejo multidisciplinario de tumores hepáticos malignos en el niño: una experiencia nacional reciente.

BACKGROUND: Malignant hepatic tumors (Mht) are rare in children. Among them hepatoblastoma (HB) is the most common. AIM: To report the results of the multidisciplinary management in 6 consecutive children: five HB and one metastatic Wilms tumor (MWT). PATIENTS AND METHODS: The mean age of patients was 42 months. All HB patients had elevated serum alfafetoprotein (median 150,000 ng/ml). All patients received preoperative chemotherapy: HB patients received carboplatin/doxorubicin alternating with cisplatin, and the MWT patient, vincristine alone. Surgery included two formal right and two formal left hepatectomies, one extensive central resection with partial left segmentectomy, and one lateral segmentectomy. Extracorporeal circulation was used in the child with atrial involvement. All patients received postoperative chemotherapy. RESULTS: All tumors had variable regresion on preoperative chemotherapy. Complete resection with negative margins was achieved in all patients. The degree of tumor necrosis on histology ranged from 60% to 90%. Alfafetoprotein levels fell to under 10 ng/ml in all HB cases, one to three months after surgery. All patients survive free of disease at a median follow up of 19 months. CONCLUSION: A multidisciplinary approach including the well timed used of chemotherapy and surgery is highly effective in the management of pediatric malignant tumors.
