Isolated Right Pulmonary Agenesis in a 2-Month-Old Infant in the Pediatric Ward of Hospital of Mali

Introduction: Pulmonary agenesis is a rare congenital abnormality defined by the absence of parenchyma, bronchi and pulmonary vessels, frequently associated with other malformations. We describe a case of isolated right pulmonary agenesis diagnosed in the pediatric ward of the Mali Hospital. Clinical case: He was a month-old baby boy, born at term by cesarean section of a well-followed pregnancy. He was not resuscitated. He developed dyspnea after a cold. An emergency chest X-ray revealed a right opaque lung. He was referred to the hospital for the exploration of this opacity. At the entrance, it weighed 3910 g, size: 54 cm and the temperature was 36.9°C. He had a polypnea, an intercostal print. The sounds of the heart were diverted to the right. The rest of the clinical examination was without much particularity. The chest CT scan confirmed the right pulmonary agenesis. Abdominal and cardiac ultrasound was normal. A healing includes oxygenotherapy, serum glucose 10% minding 100 ml/ Kg/day and amoxicillin minding 100 mg/ Kg/day at 3 times by oral way. After 24 hours of treatment, we observed an improvement in dyspnea. On D2, he was weaned off oxygen and resumed feeding. Conclusion: Pulmonary agenesis is a rare congenital anomaly that is frequently associated with other malformations, thus making its prognosis poor. The search for malformative abnormalities should be systematic in right pulmonary agenesis.

Utility of flexible fiberoptic bronchoscopy for critically ill pediatric patients:A systematic review

AIM: To investigate the diagnostic yield, therapeutic efficacy, and rate of adverse events related to flexible fiberoptic bronchoscopy(FFB) in critically ill children. METHODS: We searched Pub Med, SCOPUS, OVID, and EMBASE databases through July 2014 for English language publications studying FFB performed in the intensive care unit in children < 18 years old. We identified 666 studies, of which 89 full-text studies were screened for further review. Two reviewers independently determined that 27 of these studies met inclusion criteria and extracted data. We examined the diagnostic yield of FFB among upper and lower airway evaluations, as well as the utility of bronchoalveolar lavage(BAL). RESULTS: We found that FFB led to a change in medical management in 28.9%(range 21.9%-69.2%) of critically ill children. The diagnostic yield of FFB was 82%(range 45.2%-100%). Infectious organisms were identified in 25.7%(17.6%-75%) of BALs performed, resulting in a change of antimicrobial management in 19.1%(range: 12.2%-75%). FFB successfully reexpanded atelectasis or removed mucus plugs in 60.3%(range: 23.8%-100%) of patients with atelectasis. Adverse events were reported in 12.9%(range: 0.5%-71.4%) of patients. The most common adverse effects of FFB were transient hypotension, hypoxia and/or bradycardia that resolved with minimal intervention, such as oxygen supplementation or removal of the bronchoscope. Serious adverse events were uncommon; 2.1% of adverse events required intervention such as bag-mask ventilation or intubation and atropine for hypoxia and bradycardia, normal saline boluses for hypotension, or lavage and suctioning for hemorrhage. CONCLUSION: FFB is safe and effective for diagnostic and therapeutic use in critically ill pediatric patients.

Improving antibiotic prescribing in the emergency department for uncomplicated community-acquired pneumonia

BACKGROUND:The Pediatric Infectious Disease Society(PIDS)and Infectious Disease Society of America(IDSA)published an evidence-based guideline for the treatment of uncomplicated communityacquired pneumonia(CAP)in children,recommending aminopenicillins as the first-line therapy.Poor guideline compliance with 10%–50%of patients admitted to the hospital receiving narrow-spectrum antibiotics has been reported.A new clinical practice guideline(CPG)was implemented in our emergency department(ED)for uncomplicated CAP.The aim of this study was to examine baseline knowledge and ED provider prescribing patterns pre-and post-CPG implementation.METHODS:Prior to CPG-implementation,an anonymous case-based survey was distributed to evaluate knowledge of the current PIDS/IDSA guideline.A retrospective chart review of patients treated in the ED for CAP from January 2015 to February 2017 was performed to assess prescribing patterns for intravenous(IV)antibiotics in the ED at Children’s National Health System pre-and post-CPG implementation.RESULTS:ED providers were aware of the PIDS/IDSA guideline recommendations,with 86.4%of survey responders selecting ampicillin as the initial antibiotic of choice.However,only 41.2%of patients admitted to the hospital with uncomplicated CAP pre-CPG received ampicillin(P<0.01).There was no statistically signifi cant increase in ampicillin prescribing post-CPG(P=0.40).CONCLUSIONS:Providers in the ED are aware of the PIDS/IDSA guideline regarding the first-line therapy for uncomplicated CAP;however,this knowledge does not translate into clinical practice.Implementation of a CPG in isolation did not significantly change prescribing patterns for uncomplicated CAP.

Time Course of Elevations in Plasma Olprinone Concentration during Pediatric Cardiac Surgery

Purpose: Little research has been reported to date on the usefulness of olprinone in pediatric cardiac surgery, and no standard pediatric infusion protocol is currently established. Our study sought to confirm that the regimen described herein rapidly achieves the requisite plasma olprinone concentrations. Methods: For the purposes of our study, we enrolled 13 patients: 7 biventricular repair candidates and 6 Fontan-type operation candidates. We administered a continuous infusion of olprinone to our study subjects at 0.3 μg/kg/min with no loading dose starting approximately 30 minutes (min) before weaning from cardiopulmonary bypass (CPB). We performed blood sampling at 15, 30, 45, 60, 90, and 120 min after the start of infusion and at the same elapsed intervals after separation from CPB. We measured plasma olprinone concentrations using ultra-fast liquid chromatography. Results: We observed effective plasma olpri-none concentrations (>20 ng/ml) at 30 min after weaning from CPB, or at 60 min after the start of infusion. Conclusion: We conclude that continuous olprinone infusion at 0.3 μg/kg/min without a loading dose initiated immediately after the release of aortic cross-clamping or immediately after the completion of all surgical procedures quickly and reliably achieves effective plasma concentrations.

Medium-Term Results of Balloon Valvuloplasty of Native Pulmonary Valve Stenosis with and without Supravalvular Obstruction in Childhood

Objectives:Factors influencing results of balloon valvuloplasty(BVP)of pulmonary valve stenosis(PS)in children are investigated.Background:BVP has become the standard of care for PS,medium-term results are not uniform and depend on various preconditions.Methods:We analysed the medium-term results of BVP of PS in children in an observational,single centre study.Need for additional procedure was defined as outcome after initial BVP.Results:We included 143 children(83 female)at a median(IQR)age of 2.6(0.26–9.24)months and body weight of 5(3.4–8)kg at BVP with a follow–up of 5.04(1.6–10.2)years.We used balloon size of 10(9–14)mm and maximal balloon pressure of 4(3.5–10)atm,resulting in balloon–to–pulmonary annulus ratio of 1.28(1.2–1.4).Systolic pressure gradient of PS was reduced with BVP(43.5 mmHg vs.14.0 mmHg,p<0.001)and confirmed by echocardiography(68.0 mmHg vs.25.0 mmHg,p<0.001)day 1 post procedure.Pulmonary BVP with associated supravalvular PS resulted in a relevant reduction of systolic pressure gradient in 23 of 31 patients(74.2%).Early additional procedure was necessary in 14 patients(9.8%)after 0.2(0.1–0.7)years due to residual PS(n=13)and infective endocarditis(n=1).Factors for additional procedures were associated supravalvular PS with a higher residual pressure gradient,but not genetic syndrome.During further follow–up of 5.04(1.6–10.2)years no further additional procedures were needed.Conclusions:Pulmonary BVP of native pulmonary valve stenosis leads to excellent medium-term results,even in 3 of 4 infants with associated supravalvular obstruction sufficient pressure relief can be obtained.

Prediction of Pulmonary Arterial Pressure Level after Repair of Congenital Cardiac Communications and Discharge from the Hospital: Role of Down Syndrome and Early Postoperative Hemodynamics

Background:Postoperative pulmonary hypertension limits the success of surgical treatment in some patients with unrestrictive congenital cardiac communications.Identifying patients at risk of developing postoperative pulmonary hypertension is important to individualize follow-up strategies.Methods:We analyzed a prospective cohort of 52 pediatric patients(age 3 to 35 months)looking for perioperative predictors of mildly elevated pulmonary arterial pressure 6 months after surgery,defined as a systolic pressure greater than 30 mmHg by transthoracic echocardiography.This corresponds to a mean pulmonary arterial pressure of>20 mmHg.Clinical,echocardiographic and hemodynamic parameters were investigated.Perioperative hemodynamics was assessed by directly measuring pulmonary and systemic arterial pressures using indwelling catheters.Early postoperative pulmonary hemodynamics was defined as the mean pulmonary/systemic mean arterial pressure ratio(PAP/SAP)obtained per patient during the first 6 h of postoperative care.Results:Among the factors that were investigated as possible predictors,perioperative hemodynamics and the presence of Down syndrome were initially selected using univariate analysis(p<0.030).Early postoperative PAP/SAP was correlated with PAP/SAP obtained in the operating room just after cardiopulmonary bypass(r=0.70,p<0.001),and it was higher in subjects with Down syndrome than in nonsyndromic individuals(p=0.003).Early postoperative PAP/SAP was the only predictor selected using multivariate analysis.It was characterized as an independent predictor after adjustments for possible confounders.An early postoperative PAP/SAP of>0.35 was 76%sensitive and 74%specific at predicting a systolic pulmonary arterial pressure of>30 mmHg 6 months after surgery(hazard ratio with 95%CI 8.972[2.428–33.158],p=0.002).Conclusion:The hypertensive early postoperative behavior of the pulmonary circulation was strongly but not exclusively associated with Down syndrome,and it was characterized as an independent predictor of altered pulmonary arterial pressure after discharge from the hospital.

Massive pulmonary embolism in Klippel-Trenaunay syndrome after leg raising:A case report

BACKGROUND Klippel-Trenaunay syndrome(KTS)is a rare congenital disorder characterized by a combination of capillary malformations,soft-tissue or bone hypertrophy,and varicose veins or venous malformations.The syndrome predisposes patients to hypercoagulable states,including venous thromboembolism and pulmonary embolism(PE).CASE SUMMARY A 12-year-old girl with KTS was scheduled excision of verrucous hyperkeratosis in the left foot and posterior aspect of the left leg and left thigh and excision of a cutaneous hemangioma in the right buttock.After induction,the surgeon elevated the patient’s leg for sterilization,whereupon she experienced a massive PE and refractory cardiac arrest.Extracorporeal membrane oxygenation(ECMO)was performed after prolonged resuscitation,and she had a return of spontaneous circulation.After this episode,the patient was discharged without any neurologic complications.CONCLUSION The mechanism of PE,a lethal disease,involves a preexisting deep vein thrombosis that is mechanically dislodged by compression or changing positions and travels to the pulmonary artery.Therefore,patients predisposed to PE should be prescribed prophylactic anticoagulants.If the patient has unstable vital signs,resuscitation should be started immediately,and extracorporeal cardiopulmonary resuscitation should be considered in settings with existing ECMO protocols,expertise,and equipment.Awareness of PE in patients with KTS while leg raising for sterilization is critical.

Current Status of Community-Acquired Pneumonia in Patients with Chronic Obstructive Pulmonary Disease

Objective：Worldwide,community-acquired pneumonia （CAP） is a common infection that occurs in older adults,who may have pulmonary comorbidities,including chronic obstructive pulmonary disease （COPD）.Although there have been clinical studies on the coexistence of CAP with COPD,there remain some controversial findings.This review presents the current status of COPD in CAP patients,including the disease burden,clinical characteristics,risk factors,microbial etiology,and antibiotic treatment.Data Sources：A literature review included full peer-reviewed publications up to January 2018 derived from the PubMed database,using the keywords ＂community-acquired pneumonia＂ and ＂chronic obstructive pulmonary disease＂.Study Selection：Papers in English were reviewed,with no restriction on study design.Results：COPD patients who are treated with inhaled corticosteroids are at an increased risk of CAP and have a worse prognosis,but data regarding the increased mortality remains unclear.Although Streptococcus pneumoniae is still regarded as the most common bacteria isolated from patients with CAP and COPD,Pseudomonas aeruginosa is also important,and physicians should pay close attention to the occurrence of antimicrobial resistance,particularly in these two organisms.Conclusions：COPD is a common and important predisposing comorbidity in patients who develop CAP.COPD often aggravates the clinical symptoms of patients with CAP,complicating treatment,but generally does not appear to affect prognosis.

肺部超声在小儿肺部疾病中的应用进展

超声在诊断实性脏器、含液性脏器及浅表组织等疾病方面具有准确、经济、非侵入性等优点。既往认为超声仅用于诊断胸膜炎、胸腔积液等肺部疾病,近年认为超声在其他肺部疾病(气胸、肺炎、肺间质病变、呼吸窘迫综合征、先天性肺畸形等)诊断方面也具有潜力。由于气体的存在和胸廓的干扰,肺脏不适用超声检查,而小儿胸腔的特殊解剖结构使其可通过超声检查时肺表面产生的超声伪像(B线)诊断肺部疾病,因此肺部超声被认为是诊断肺部疾病的有效方法之一,特别是小儿,基本上可以替代X线,以防电离辐射。
