Infect Drug Resist 2024; 17:1961-1969. [PMID: 38779350 PMCID: PMC11108758 DOI: 10.2147/idr.s459626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 04/29/2024] [Indexed: 05/25/2024] Open
Abstract
Purpose To explore the clinical characteristics, treatment, and long-term prognosis of mycoplasma pneumoniae pneumonia (MPP) combined with pulmonary embolism (PE) in children. Patients and Methods The medical records of 16 children who were diagnosed with MPP associated with PE between January 2016 and January 2023 at Children's Hospital, Zhejiang University School of Medicine were retrospectively reviewed. Results The average age patients were 8.24 ± 1.99 years. All cases were diagnosed with refractory mycoplasma pneumoniae pneumonia (RMPP) and presented complications in the form of necrotizing pneumonia (NP). The main symptoms observed were cough and fever (n = 16, 100%), chest pain (n = 8, 50%), dyspnea (n = 8, 50%), and hemoptysis (n = 4, 25%). In these cases, 12 patients had involvement of the pulmonary artery, 3 patients experienced issues with the pulmonary vein, and 1 patient had simultaneous involvement of both the pulmonary artery and pulmonary vein. Among the 12 pulmonary artery embolism cases, 6 involved the right pulmonary artery, 4 involved the left pulmonary artery, and 2 involved both the right and left pulmonary arteries. The mean D-dimer level was 8.50 ± 4.76 mg/L. All patients received anticoagulant therapy, and after treatment, there was a significant improvement in their symptoms and lung lesions. Conclusion Children with RMPP, chest pain, hemoptysis, and elevated D-dimer levels should be closely monitored for the potential development of PE. The co-occurrence of MPP and PE often involves the presence of NP. In cases of confirmed PE, anticoagulation therapy may be a suitable consideration. PE and NP resulting from MPP generally had a favorable overall prognosis.

Front Endocrinol (Lausanne) 2024; 15:1292025. [PMID: 38681768 PMCID: PMC11047119 DOI: 10.3389/fendo.2024.1292025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2023] [Accepted: 03/12/2024] [Indexed: 05/01/2024] Open
Abstract
Background Craniopharyngioma (CP), although slow growing and histologically benign, has high morbidity, mostly related to hypothalamus-pituitary dysfunction and electrolyte imbalance. Increased risk of vascular complications has been described. However, data are still poor, especially in the paediatric population. The aim of our study was to evaluate the occurrence, timing, and predisposing factors of deep venous thrombosis (DVT) and other vascular alterations in neurosurgical paediatric CP patients. Materials and Methods In a single-centre, retrospective study, we investigated 19 CP patients (11 males, 8 females, mean age 10.5 ± 4.3 years), who underwent neurosurgery between December 2016 and August 2022, referred to Meyer Children's Hospital IRCCS in Florence. Results Five patients (26.3%) presented vascular events, which all occurred in connection with sodium imbalances. Three DVT (two with associated pulmonary embolism, in one case leading to death) developed in the post-operative period, most frequently at 7-10 days. Elevated D-dimers, a reduced partial activated thrombin time and a prolonged C-reactive protein increase were highly related to thrombotic vascular events. One case of posterior cerebral artery pseudoaneurysm was described soon after neurosurgery, requiring vascular stenting. Superficial vein thrombophlebitis was a late complication in one patient with other predisposing factors. Conclusion CP patients undergoing neurosurgery are at risk of developing DVT and vascular alterations, thus careful follow-up is mandatory. In our study, we found that the phase of transition from central diabetes insipidus to a syndrome of inappropriate antidiuretic hormone secretion may be a period of significant risk for DVT occurrence. Careful vascular follow-up is mandatory in CP-operated patients.

Abstract
OBJECTIVE This study aimed to investigate the clinical characteristics and long-term prognosis of mycoplasma pneumoniae pneumonia (MPP)-associated thrombosis and to gain a better understanding of the diagnosis and treatment of the disease. METHODS The medical records of 14 children with MPP-associated thrombosis between January 2016 and April 2020 were retrospectively reviewed at the Tianjin Children's Hospital. RESULTS The ages of the patients ranged from 3 to 12 years old. Among the 14 cases, there were five cases of pulmonary embolism, two cases of cerebral infarction, one case of splenic infarction, one case of cardiac embolism, two cases of cardiac embolism with comorbid pulmonary embolism, one case of internal carotid artery and pulmonary embolism, one case of combined internal carotid artery and the cerebral infarction, and one case combined cardiac embolism and lower limb artery embolism. All cases had elevated D-dimer levels. After thrombolysis and anticoagulation therapy, three cases with cerebral embolism still suffered from neurological sequelae. In contrast, the remaining cases did not develop complications. CONCLUSION MPP-associated thrombosis can occur in any vessel of the body. Thrombosis-associated symptoms may be complex and non-specific. Elevated D-dimer levels in a child with refractory mycoplasma pneumoniae pneumonia should raise suspicion of thrombosis. The long-term prognosis of thrombosis was favorable after the timely administration of anticoagulant therapy.

Abstract
Venous thromboembolism (VTE) in children is a rare occurrence, although in recent decades we have seen an increase due to several factors, such as the rise in survival of subjects with chronic conditions, the use of catheters, and the increased sensitivity of diagnostic tools. Besides inherited thrombophilia, acquired conditions such as cardiovascular diseases, infections, chronic disorders, obesity and malignancy are also common risk factors for paediatric VTE. The treatment of paediatric VTE consists of the use of heparins and/or vitamin K antagonists to prevent dissemination, embolization, and secondary VTE. Randomized clinical trials of direct oral anticoagulants in paediatric VTE are ongoing, with the aim to improve the compliance and the care of patients. We reviewed the physiological and pathological mechanisms underlying paediatric thrombosis and updated the current diagnosis and treatment options.

Abstract
Central venous access is frequently essential for the management of many acute and chronic conditions in children. Millions of central venous access devices (CVADs) are placed each year. In this review article, we discuss the indications for long-term vascular access, the types of devices available, the state of the art of central venous cannulation and device placement, and the complications of long-term central venous access. We pay a special attention to the challenges of, and options for long-term central venous access, also those in developing countries, with limited financial, human, and material resources.

Abstract
BACKGROUND Venous thromboembolism (VTE) - which includes deep venous thrombosis (DVT) and pulmonary embolism (PE) - has been increasingly recognized in the pediatric population. The estimated incidence is 0.07-0.14 cases per 10,000 children. Most cases are associated with two or more risk factors. Medium and long-term complications include recurrence and post-thrombotic syndrome (PTS). OBJECTIVE To characterize the adolescent population with the diagnosis of DVT of lower limbs in a tertiary hospital, regarding its clinical presentation, associated risk factors, treatment and outcome. METHODS Retrospective analysis of adolescents with the diagnosis of DVT of lower limbs in our hospital for a period of 7 years. RESULTS Eight patients were identified; seven were females; median age was 15 years. The main symptoms were local pain and edema. Left lower limb was affected in six patients. PE occurred in two cases. Positive family history of venous thromboembolism was found in five patients. Seven patients had at least two identifiable risk factors. Combined oral contraceptive pill use was the most common (seven patients). Factor V Leiden mutation was found in three patients and protein C deficiency in one. Iliac vein compression syndrome was diagnosed in one patient. The median time for discharge was 8 days. Election treatment was enoxaparin followed by warfarin, for a median period of 10.9 months. Three patients developed PTS. CONCLUSIONS Although uncommon, VTE is an emerging reality in adolescents, particularly in females using oral contraceptive pills. Appropriated prevention strategies and treatment are required as most orientations are extrapolated from adults.

Abstract
Using the 2012 Kids Inpatient Database, we assessed records of pediatric patients (<21 years old) with fractures of the upper limb, lower limb, spine, pelvis, and multiple locations and calculated the overall prevalence of venous thromboembolism (VTE) and associated potential risk factors. 387 (0.68%) of 57 183 patients with one or more fractures were diagnosed with VTE. Children sustaining fractures of the axial skeleton and those with multiple fractures had a higher prevalence of VTE than those with isolated extremity fractures. Associated risk factors included the presence of a central venous catheter. A prospective, multicenter study is needed to confirm our findings.

Abstract
BACKGROUND The Italian Registry of Thrombosis in Children (RITI) was established by a multidisciplinary team with the aims of improving knowledge about neonatal and paediatric thrombotic events in Italy and providing a preliminary source of data for the future development of specific clinical trials and diagnostic-therapeutic protocols. MATERIALS AND METHODS We analysed the subset of RITI data concerning paediatric systemic venous thromboembolic events that occurred between January 2007 and June 2013. RESULTS Eighty-five deep venous thromboses and seven pulmonary emboli were registered in the RITI. A prevalence peak was observed in children aged 10 to 18 years and, unexpectedly, in children aged 1 to 5 years. A central venous line was the main risk factor (55% of venous thromboembolic events); surgery (not cardiac) (25%), concomitant infections (23%) and malignancy (22%) were the clinical conditions most often associated with the onset of venous thromboembolism. There was a diagnostic delay of more than 24 hours in 37% of the venous thromboembolic events. Doppler ultrasound was the most widely used test for the objective diagnosis of deep venous thrombosis (87%). Antithrombotic therapy was administered in 96% of venous thromboembolic events, mainly low molecular weight heparin (60%). In 2% of cases recurrences occurred, while post-thrombotic syndrome developed in 8.5% of cases. DISCUSSION Although the data from the RITI are largely in agreement with published data, peaks of prevalence of thrombosis, risk factors and objective tests used for the diagnosis showed some peculiarities which may deserve attention.

Abstract
Descending iliofemoral thrombosis in children is a rare event. Anticoagulation therapy with low-molecular-weight-heparin is standard of care. However, patency cannot be achieved in all cases, increasing the risk for rethrombosis and postthrombotic syndrome. To reduce the risk of venous valve failure in adults, local catheter-directed thrombolysis is used to reopen vessels. Two adolescent girls (17 and 15 years old) presented with acute descending iliofemoral thrombosis of the left common iliac, external, and common femoral veins. Anticoagulation with enoxaparin was started until insertion of an EkoSonic Mach 4e catheter for ultrasound-assisted local thrombolysis with recombinant tissue plasminogen activator and administration of unfractionated heparin. Success was monitored by increases in D-dimer levels and ultrasound findings. After 24 hours respectively 48 hours, complete recanalization was obtained. No complication occurred except minimal local bleeding. Screening for hereditary thrombophilia revealed a heterozygous antithrombin mutation in 1 girl (ie, the 15-year-old). May-Thurner syndrome was identified in both girls, necessitating stenting of the left common iliac veins and continuation of anticoagulation therapy with enoxaparin and acetylsalicylic acid. No rethrombosis or complications occurred during the follow-up period. Ultrasound-assisted catheter-directed local thrombolysis with the EkoSonic Mach 4e system was effective in achieving immediate recanalization of the occluded veins and should be considered in children experiencing descending iliofemoral thrombosis. The fast recanalization might reduce the incidence of postthrombotic syndrome. May-Thurner syndrome is regularly found in these patients, and if present, requires stenting of the common iliac vein to avoid early reocclusion. However, long-term patency of iliac vein stenting in children remains to be examined.

Abstract
BACKGROUND Although venous thromboembolism (VTE) has been well studied in the pediatric trauma population, rates of VTE associated with elective pediatric orthopaedic procedures have not been addressed in current literature. The purpose of this retrospective study was to identify the incidence of VTE in the elective pediatric orthopaedic surgical population and delineate subsets of this population at greatest risk. This study may provide valuable data to begin the process of resolving the controversy surrounding deep vein thrombosis prophylaxis in the pediatric orthopaedic population. METHODS The Pediatric Health Information System was queried for patients admitted on an ambulatory or inpatient basis, aged below 18 years, from January 2006 to March 2011 during which an elective orthopaedic surgery was the principal procedure performed. Patients with diagnoses or procedures related to infection, trauma, malignancy, or coagulopathies were excluded. Patients admitted through the emergency department or whose orthopaedic procedure was not performed on the admission date were excluded. Age, sex, ethnicity, race, admission year, and all procedures/diagnoses were recorded. The presence of VTE at the index admission or any subsequent readmission within 90 days was recorded. All criteria were coded using ICD-9-CM codes. Generalized logistic regression analyses were used to identify factors related to VTE. RESULTS A total of 143,808 admissions (117,676 patients) matched the inclusion criteria. Thirty-three had a VTE during the index admission with an additional 41 at subsequent readmissions, for a total incidence of 0.0515% by admission and 0.0629% by patient. In the multivariable model, variables significantly (P<0.05) related to VTE included increasing age, admission type, diagnosis of metabolic conditions, obesity, and/or syndromes, and complications of implanted devices and/or surgical procedures. No procedure variables were significantly related to VTE in the multivariable model. CONCLUSIONS The incidence of VTE in this cohort of pediatric patients undergoing elective orthopaedic surgery was 0.0515%. In children, underlying diagnosis seems to be a stronger predictor of VTE than procedures performed. Diagnosis with a metabolic condition, syndrome, and/or obesity, complications of implanted devices and/or surgical procedures, older age, and admission as an inpatient were significantly related to the development of a VTE.

Abstract
Recent literature has reported an apparent increase in the incidence of pediatric venous thromboembolism over the last 10 years. In our study, data were collected from all children (ages 0 to 18 y) with a thrombotic event between January 2000 and May 2012, to determine whether an increased incidence of thromboembolism (TE) was evident and to investigate mitigating factors in the development of the TE. A total of 134 patients were entered into the study, 42% under the age of 1 year. There was no conclusive evidence of an increased incidence in our population over the period of the study. Within our population the peripheral venous system was the most common location for TE followed by cerebral vascular accidents. A thrombophilic risk factor was found in 84% of the patients. In our study 4.5% of the children had a second event.

Abstract
Low-molecular weight heparins are currently the most commonly used anticoagulants in children and newborns. However, since thrombotic complications rarely occur outside large children's hospitals, physicians often encounter some practical problems in managing these treatments when a pediatric thrombosis specialist is not available. The drug of choice is enoxaparin, due to its favorable FXa/FIIa ratio and the availability of pharmacokinetic and pharmacodynamic data. The treatment of acute thrombosis should be started with two daily injections but when compliance is an issue, a single daily administration schedule could be chosen for secondary prophylaxis ensuring careful measurement of the post 24-hour anti-FXa activity. Furthermore, a subcutaneous device may be a useful tool and a topical dermal anesthetic could be effective in controlling pain without affecting anti-FXa levels. In neonate and toddlers, where mini doses are frequently needed, the dead space of syringes and needles could represent an issue and therefore the use of insulin syringes without dead space is advisable, while a dilution of the drug is useful with other syringes. This article derives from a nonsystematic review of the available literature, with special attention to recent international guidelines and expert recommendations, combined to authors' clinical practice in large tertiary pediatric hospitals and will provide concise and practical information for the use of low-molecular weight heparin in childhood and infancy in a sort of "answering frequently asked questions."

Abstract
We performed a systematic review of published studies that evaluated the potential risk factors and outcomes of venous thromboembolism (VTE) in hospitalized children. A total of 761 VTE patients from six published studies were identified. The mean prevalence of VTE in children admitted to the hospital was 9.7/10 000 admissions. The presence of a central venous catheter was found to be the single most important predisposing cause of VTE, with a pooled percentage of 29%. Infection was the second most common cause of the disease (20%). Pulmonary embolism occurred in 15% (113/745) of the patients. The overall recurrence rate of VTE was 16% (74/464) and the mortality rate was 8% (59/704). Although uncommon, orthopedic surgeons need to be aware of the unique risk factors for VTE among pediatric inpatients. Hospitalized children and adolescents with known risk factors for VTE should be considered candidates for VTE screening or prophylaxis.

Abstract
BACKGROUND The term venous thromboembolism (VTE) includes deep venous thrombosis of the extremity and pulmonary embolism, a potentially fatal clinical entity. Although the prevalence of VTE may be lower in children compared with adults, recent reports suggest a possible rise in this diagnosis among pediatric patients, especially in association with certain risk factors. We assessed the clinical experience and practice of members of the Pediatric Orthopaedic Society of North America (POSNA) related to VTE among their pediatric patients. METHODS A 36-question online survey was sent to all 636 active POSNA members. The proportion of surgeons who had encountered at least 1 child with VTE and the respondents' practice of using thromboprophylaxis in children (<18 y old) was assessed. The relationship of responders' experience with VTE among pediatric patients with various practice characteristics was evaluated. RESULTS The response rate was 56% (354/636). More than half (55%) [95% confidence interval (CI), 50%-60%] of the respondents could recall at least 1 (median, 2 cases/member) pediatric patient with deep venous thrombosis and 29% (95% CI, 24%-34%) could recall ≥1 child with pulmonary embolism. Approximately one quarter (23%) (95% CI, 18%-27%) of all respondents reported never using mechanical prophylaxis and almost one half (45%) (95% CI, 40%-50%) of respondents reported never using pharmacologic prophylaxis against VTE in children. Only 16% (95% CI, 12%-20%) of the respondents had a thromboprophylaxis protocol for pediatric patients. Respondent characteristics such as being in clinical practice <5 years (P=0.01) and having a surgical volume of <100 cases/y (P=0.03) were associated with a lower likelihood of encountering a pediatric patient with VTE. CONCLUSIONS More than half of responding active POSNA members reported having come across at least 1 case of VTE among pediatric patients during their practice. The routine use of VTE prophylaxis for children is uncommon among pediatric orthopaedists. Further studies aimed at determining the prevalence of VTE and developing specific guidelines for prophylaxis among pediatric patients seeking orthopaedic care are warranted. LEVEL OF EVIDENCE IV.
