肺炎支原体肺炎闭塞性支气管炎1 例报告并文献复习

目的探讨肺炎支原体肺炎(MPP)闭塞性支气管炎的临床特点。方法回顾分析1例MPP闭塞性支气管炎患儿的临床资料,并复习相关文献,总结MPP继发闭塞性支气管炎的临床、影像学及支气管镜下特点。结果 4岁男童,以重症MPP 1月余后气促、活动不耐受为主要临床表现,体检发现左侧胸廓塌陷,左肺呼吸音低。肺部影像学示纵隔心影左移,左肺下叶不张,左肺下叶各段支气管扩张,右肺马赛克灌注征。支气管镜下见左上舌段、左下前外基底段亚支闭塞。经2次支气管镜球囊扩张、支气管肺泡灌洗及布地奈德雾化吸入等治疗,半年后胸部CT示部分肺复张。检索到19篇文献,72例患儿,其中有MPP病史49例。在MPP后1～2个月内逐渐出现气促、喘息、活动不耐受等表现,体格检查多可在患侧肺闻及支气管呼吸音,影像学则以持续性肺实变或肺不张为特点,通过阿奇霉素序贯联合糖皮质激素及支气管镜等治疗,随访17例,8例有所改善。结论重症MPP后出现气促、喘息、活动耐量下降等表现,影像检查提示单侧肺不张,应警惕闭塞性支气管炎,早期支气管镜诊治可能对改善预后有一定积极作用。     

儿童闭塞性细支气管炎的研究进展

闭塞性细支气管炎是指小气道损伤后炎症及纤维化引起的慢性气流阻塞的临床综合征,儿童表现为重症呼吸道感染后持续咳嗽、喘息及活动不耐受.重症下呼吸道感染、心肺移植、骨髓移植、Stevens-Johnson综合征、结缔组织病、吸入或摄入有毒物质及药物因素等均可导致闭塞性细支气管炎的发生.闭塞性细支气管炎诊断主要依据临床表现、高分辨率CT和肺功能检查,肺组织活检是诊断闭塞性细支气管炎的金标准.目前尚没有公认的闭塞性细支气管炎治疗准则.早期阶段是临床治疗的关键时期.多数采取持续使用糖皮质激素和支气管舒张剂,同时联合其他支持治疗.该文从病因、发病机制、病理、临床表现、辅助检查、诊断、鉴别诊断及治疗方面对儿童闭塞性细支气管炎进行综述.

儿童肺炎支原体肺炎细菌性肺炎所致塑型性支气管炎15例临床分析

目的 分析儿童肺炎支原体肺炎和（或）细菌性肺炎所致塑型性支气管炎的临床特点。方法 回顾性收集2007年1月至2010年3月在首都医科大学附属北京儿童医院诊断为塑型性支气管炎患儿的临床资料。依据其感染病原分为肺炎支原体肺炎组、肺炎支原体肺炎合并细菌感染组和细菌性肺炎组。分析3组患儿临床表现（发热、咳嗽、肺部体征、发热峰值及发热持续时间等）、实验室检查（WBC、CRP、转氨酶和病原培养等）、胸部CT、支气管镜所见气道黏膜损害、支气管塑型分泌物栓病理学检查和治疗情况。结果 15例塑型性支气管炎患儿进入分析,年龄2~15岁。肺炎支原体肺炎组5例,肺炎支原体肺炎合并细菌感染组6例,细菌性肺炎组4例。3组患儿均急性起病,均以发热和咳嗽为主要表现入院。①肺炎支原体肺炎组均无急性呼吸窘迫和肺外阳性体征;肺炎支原体肺炎合并细菌感染组需呼吸支持者和伴肺外阳性体征者均为1/6例;细菌性肺炎组需呼吸支持者和伴肺外阳性体征者均为3/4例。②3组胸部CT检查均提示单侧或双侧肺实变,肺不张和胸腔积液肺炎支原体肺炎组分别为1/5例和3/5例,肺炎支原体肺炎合并细菌感染组分别为3/6例和5/6例,细菌性肺炎组分别为3/4例和1/4例。③3组支气管镜检查均可见气道黏膜充血和肿胀,但程度和范围以肺炎支原体肺炎合并细菌感染组和细菌性肺炎组为著;气道黏膜局部损害以肺炎支原体肺炎合并细菌感染组为著,其中2例伴支气管通气不良,有远端支气管闭塞可能。④3组支气管镜检查均有支气管树样塑型分泌物栓栓取出,病理组织学分型均为Ⅰ型。结论 与细菌性肺炎相比,肺炎支原体肺炎在全身炎症反应较轻时即可发生塑型性支气管炎。肺炎支原体肺炎所致塑型性支气管炎的气道黏膜损害较轻,支气管塑型分泌物栓较短,应及时行支气管镜检查以协助诊治。     

Pulmonary lesions mimicking pericardial effusion on ultrasonography

Two children with right middle lobe lesions mimicking pericardial effusion on ultrasonography are presented. They were admitted with fever and chest radiographs showed atelectasis or consolidation of the middle lobe of the right lung along the right heart border. A low-echogenic layer suggesting pericardial fluid was seen on ultrasonography, but with a spatial distribution closely corresponding to the lesions seen on the chest radiographs. If the possibility that a lung lesion adjacent to the heart can simulate pericardial fluid on ultrasonography is kept in mind, the correct diagnosis should not be difficult to make.     

Massive lung collapse with partial resolution after several years: a case report

Background  

Bronchitis obliterans is a severe and extremely rare complication of respiratory tract infections in children and is characterized by massive atelectasis and collapse of the affected lung. Of the rare cases reported in the literature all surviving children underwent surgical resection of the collapsed lung.     

The therapeutic significance of bronchial suction-drainage in infants]

Bronchial suction-drainage in infants--according to our observations--is a life-saving procedure in cases of aspiration, severe bronchitis and retention of bronchial secretion. It can also be very effective in atelectasis, bronchopneumonia and pulmonary abscess. The earlier the drainage the quicker the clearing up of the atelectasis. An additional indication for performing bronchial suction in severe lower respiratory tract infections is to gagain secretion for bacterial culture. This is especially important in the Gram negative and Staphylococcus infections of young infants. The right upper pulmonary lobe is the most common localisation for atelectasis and pneumonia in this age group. One possible explanation for this could be that malformed bronchi are more frequently found in the right than in the left upper lobe. It is such a characteristical phenomenon in infancy that we called it "the right upper lobe syndrome".     

Mucoepidermoid carcinoma as an unusual cause for recurrent respiratory infections in a child

Recurrent respiratory infections in a 9-year-old girl prompted a chest radiograph and a CT scan, which showed a right middle lobe consolidation. Bronchoscopy revealed a tumor that totally obstructed the middle lobe. Open lung biopsy revealed a low-grade mucoepidermoid carcinoma. Middle and lower right lung lobectomy was performed, followed by an uneventful recovery. Cytogenetic investigation of tumor cells exhibited the translocation t(11;19). This case shows that further diagnostic modalities such as CT scanning should be performed early in children with recurrent lower respiratory tract infections who have suspicious radiographic findings such as persistent atelectasis or recurrent unifocal infiltration. Bronchial mucoepidermoid carcinoma is infrequent, and molecular investigations might shed additional light on the prognosis.     

中国儿童间质性肺疾病的临床研究

目的 了解中国儿童间质性肺疾病( ILD)的病因谱.方法 以2009年来自全国11家医院就诊的93例儿童ILD患者为研究对象,采用统一登记表格,详细记录其病史、症状、体征;所有病例均进行胸CT或高分辨率CT;住院期间常规检查项目包括血常规、血沉、C反应蛋白、血气分析,据病情轻重和年龄尽可能进行肺功能检查;具有诊断意义的项目包括呼吸道分泌物细菌培养、呼吸道病毒抗原检测、血清的病毒和支原体抗体检查,以及血清学的免疫抗体检查,痰、胃液、肺泡灌洗液涂片找含铁血黄素细胞等;对25例病例进行了支气管镜检,对14例病例进行了肺活检.由全国儿童弥漫性实质性肺疾病/间质性肺疾病协作组成员对每一病例进行集体讨论诊断.14例病例按临床-放射-病理(C-R-P)诊断模式达成诊断共识,79例病例根据临床及典型影像学改变、辅助检查做出最后诊断.结果 93例ILD患儿年龄8个月～14岁,平均年龄为4岁11个月,其中男53例,女40例.(1)93例ILD的病因谱为:闭塞性细支气管炎39例;特发性肺含铁血黄素沉着症39例;特发性间质性肺炎7例(其中非特异性间质性肺炎4例,急性间质性肺炎1例,淋巴细胞间质性肺炎1例,特发性肺纤维化1例);继发性的间质性肺炎2例(其中继发于系统性红斑狼疮的急性间质性肺炎1例,HIV感染引起的淋巴细胞间质性肺炎1例);外源性过敏性肺泡炎2例;闭塞性细支气管炎伴机化性肺炎1例,肺泡微石症1例,弥漫性泛细支气管炎1例,类脂性肺炎1例.(2)临床特点:72例有咳嗽,24例有气促,5例有三凹征,43例肺内可闻及湿啰音,8例有杵状指趾.(3)影像学特征:肺CT显示56例肺部有磨玻璃影;30例肺部有马赛克灌注征,其中11例伴有支气管扩张,8例伴有支气管壁增厚;1例弥漫性小叶中心性结节,伴小支气管和细支气管扩张;1例为弥漫性的细小结节影;1例为弥漫性网格影和泡性肺气肿.结论 儿童ILD是一组异质性疾病,本组共诊断出11种疾病,其中例数最多的前三位疾病为闭塞性细支气管炎、特发性肺含铁血黄素沉着症、特发性间质性肺炎.     

Cast bronchitis in infants and children

Seventy-two children (age range, 3 months to 5.5 years) with a clinical diagnosis of obstructive bronchitis (asthmatoid or spastic bronchitis or bronchiolitis) were found to have bronchial casts in the gastric fluid, and in 2 additional cases casts were spontaneously expectorated in the bronchial exudate. Cast bronchitis had a long-term course of 10 to 24 months in 65 of the 74 patients. Common radiologic findings included bronchi presumably filled with secretions, areas of atelectasis, and lung emphysema of varying degrees. Cast bronchitis did not appear to be associated with eosinophilia and elevated serum IgE levels. Therefore, an extrinsic allergic mechanism is not likely involved in the pathogenesis of the condition. Bronchial casts had varying consistencies; although they were usually soft, they were sometimes rather hard. They were hollow, often ramified, and white and measured from 0.5 to 2 cm in length. Histologically, they consisted of metaplastic squamous epithelium with a varying degree of inflammatory cells and noncellular material. Some differences in biochemical composition were observed between bronchial casts and bronchial exudate of acute catarrhal bronchitis. No viruses could be isolated in 11 cast specimens. Our results suggest that cast formation is mainly related to the metaplastic transformation of the bronchial epithelium and that this metaplasia may play an important pathophysiologic role in certain infants and children with obstructive bronchitis.     

Why mucous plugs commonly cause left lung collapse?

Sixty cases, with atelectasis/pneumonic consolidation associated with/without emphysema, aged three months to four years, were subjected to bronchoscopy. There was a preponderance of left lung pathology (40) over the right one (20). Of the 40 cases with left lung pathology, the lower lobe was involved in 88%, and the upper in 12%. Of the cases with right lung pathology upper lobe was involved in 40%, the middle lobe in 40% and the lower in 20%. There was no relationship of the laterality of the pathology attributable to the usual posture of the child during suckling. About 50% of the cases were benefited by bronchoscopic procedures. The preponderance of left lung pathology over the right in the pediatric age group is explained by the fact that an endogenous foreign body e.g. mucous plug, is more difficult to be expectorated out from the left lung than the right one because of anatomical differences. This results in retention of the blocking agent, leading to atelectasis/consolidation.     

Abnormal MIBG uptake in a neuroblastoma patient with right upper lobe atelectasis

A 3-month-old boy with a history of an abdominopelvic neuroblastoma presented 1?week after tumor resection for a routine follow-up 123-I Meta-iodobenzylguanidine (MIBG) scan to assess for residual mass. The study demonstrated abnormal radiotracer uptake in the right upper lobe, which correlated on the SPECT/CT to an area of airspace consolidation thought to be secondary to atelectasis. To the best of our knowledge, there is one published case of MIBG radiotracer uptake in the lung correlating with pneumonia; however, there are no reported cases to date in the literature of focal pulmonary MIBG uptake corresponding to atelectasis.
