Surgical treatment of a rare case of tracheal inflammatory pseudotumor in pediatric age

Tracheal inflammatory pseudotumor (IPT) is a rare solid lesion with an unpredictable biological course. Treatment can vary and surgical resection may sometimes be necessary, even in pediatric age. We report the case of a 12-year-old male patient who presented to our institution with sudden dyspnoea after some months of wheezing and cough, wrongly considered and treated as asthma. Neck-chest CT-scan and fiberbronchoscopy showed an intraluminal tracheal mass, originating from the left antero-lateral wall at the level of the 5th cartilagineous tracheal ring, involving three rings, that was removed by rigid bronchoscopy. Histopathology revealed a tracheal IPT. Due to rapid tendency to recurrence of the lesion, two more endoscopic recanalizations were performed, but a new recurrence appeared, with CT evidence of transmural involvement of the tracheal wall. Resection of the three involved tracheal rings and termino-terminal tracheal anastomosis were successfully performed through cervicotomy and sternal split. CT-scan and fiberbronchoscopy at 17 months from surgery show a stable tracheal lumen without signs of recurrence. A tracheal IPT should be suspected in any pediatric patients with tracheal mass and asthmatic symptoms. After radical removal prognosis is generally excellent and recurrences after tracheal resection are rare.

Propranolol as first-line treatment of a severe subglottic haemangioma

Subglottic haemangioma (SGH) is a rare, benign tumour in children, which is potentially life-threatening because of airway obstruction. We report the case of a full-term 2-month-old infant girl admitted to our institution with stridor, dyspnoea and oxygen desaturation caused by a SGH and treated with propranolol. Neck-chest computed tomography (CT) revealed a contrast-enhancing, 10-mm, subglottic elliptic lesion, referable to SGH. Pre-treatment fibrobronchoscopy showed a sub-occlusive SGH closing more than 75% of the laryngotracheal airway. In agreement with our neonatologists and ear, nose and throat (ENT) specialists, we decided to begin oral propranolol therapy, which rapidly and dramatically improved respiratory symptoms. Fibrobronchoscopy six days after treatment confirmed a reduction of subglottic narrowing. Six months later the patient is doing well and without respiratory symptoms. To the best of our knowledge, this is the first reported case of the successful treatment with propranolol of an SGH obstructing more than 75% of the airway. The case is evidence of the effectiveness of oral propranolol as first-line treatment in the management of severely-obstructive paediatric SGH and the importance of CT and fibrobronchoscopy in the diagnosis; it also demonstrates the importance of multidisciplinary cooperation between thoracic surgeons, anaesthesiologists, neonatologists and ENT specialists in the treatment of these patients.

Surgical treatment of a rare case of epithelioid hemangioendothelioma of the azygos vein

Epithelioid hemangioendothelioma (EHE) of soft tissues is a rare low-grade vascular tumour, with variable malignancy. Mediastinal localization is exceptional. We report the first case of a radically resected EHE of the azygos vein (AV). A 47-year old man presented to our institution with an asymptomatic incidental neck-chest computerized tomography (CT) evidence of a 3 cm mediastinal mass, resembling a station 4R lymphadenopathy, with rather distinct margins, strictly adjacent to the AV. (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET)/CT revealed a SUV max of 2.3. Fiberbronchoscopy with EBUS-trans-tracheal needle aspiration of station 4R yielded nondiagnostic cytology result. A right lateral thoracotomy revealed an ovoidal mediastinal mass originating from the AV, unresectable from it but showing cleavage from the superior vena cava. The mass with the involved AV was resected en bloc by vascular stapler. Histopathology revealed a venous EHE arising from the AV. For the low mitotic rate and small tumour size, no adjuvant therapy was administered. Total body CT scan at one year from surgery shows neither local recurrence, nor distant metastases. EHE should be considered in the differential diagnosis of mediastinal masses in adult patients. After radical removal prognosis is generally favourable, but strict follow-up must be performed because aggressive forms have been described.

Tracheal Resection With Patient Under Local Anesthesia and Conscious Sedation

The authors describe the case of a woman with a 2-year history of dyspnea and stridor caused by a tracheal hamartoma. The patient underwent tracheal resection and end-to-end anastomosis under monitored local anesthesia and conscious sedation, which was achieved by boluses of ketamine and midazolam. Local anesthesia was obtained by the use of stepwise local infiltration of 2% lidocaine and 7.5 mg/mL ropivacaine during the operation. The patient remained awake during the entire procedure, thus permitting the movement of the vocal cords to be monitored. Mechanical ventilation was never required. The postoperative period was uneventful, and the patient did not describe having any discomfort.

Early and late outcome after surgical treatment of acquired non-malignant tracheo-oesophageal fistulae

OBJECTIVES Tracheo-oesophageal fistula (TOF) is a rare, life-threatening condition. We report our results of surgical treatment and evaluation of the outcome of acquired non-malignant TOF. METHODS Twenty-five patients (aged 49 ± 21 years) with TOF were operated on between 2001 and 2011. Tracheo-oesophageal fistula was due to prolonged intubation/tracheostomy (84%), was secondary to other surgery (8%) or trauma (4%) or was idiopathic (4%). The tracheal defect was 2.4 ± 1.3 cm long and was associated with tracheal stenosis in seven (28%) patients. Surgical treatment consisted of direct suturing of the oesophageal defect in two layers (or end-to-end oesophageal resection and anastomosis in one case) associated with tracheal suturing (n = 15; 60%), tracheal resection and anastomosis (n = 8; 32%) or covering of a large tracheal defect by an intercostal muscle flap or by a resorbable patch with muscle apposition (n = 2; 8%). The surgical approach was cervicotomy (n = 14; 56%), cervicotomy plus median sternotomy or split (n = 6; 24%), thoracotomy (n = 4; 16%) or cervicotomy plus sternal spit plus thoracotomy (n = 1; 4%). In 18 (72%) cases a muscular flap was used and in six (24%) a protective tracheostomy was performed. RESULTS No perioperative deaths occurred. Morbidity occurred in eight (32%) patients; none of them required a second surgical look. At median follow-up of 41 months, the outcome was excellent or good for 22 patients (88%), two (8%) are still dependent on jejunostomy and tracheostomy for neurological diseases and one (4%) is under mechanical ventilation for end-stage respiratory failure. CONCLUSIONS Surgical treatment of TOF is associated with good results in terms of control of acute symptoms and long-term outcome, particularly concerning oral intake and spontaneous breathing.

Right-sided approach for management of left-main-bronchial stump problems

OBJECTIVE Although the incidence of bronchopleural fistula (BPF) has decreased in the past decades, it remains a serious complication following pulmonary resection. The management of left-sided bronchial stump fistulas is difficult and depends on the choice of the approach. In contrast to several surgical procedures published in the past, herein we report our experience managing five left-main-bronchial stump (LMBS) problems through a right thoracotomy route. METHODS Five women, who underwent left pneumonectomy and later developed BPF, were managed with this novel procedure at our Institution. BPF appeared between 12 days and 24 years after pneumonectomy. Diagnosis of BPF or bronchoesophageal fistula (BEF) was made by computed tomography (CT) scan and fiberoptic bronchoscopy. Through a right posterolateral thoracotomy incision, the LMBS was re-stapled and covered with pedicled flaps in all cases. In patient #4, carinal resection was performed also, with temporary extracorporeal membrane oxygenation (ECMO) application. RESULTS The main results are depicted in the table. In all cases, encircling of the LMBS and stapling at the level of the carina was performed without difficulties. In patients #1, #2 and #3, resection of the bronchial stump remnant was also done and, in patient #4, carinal resection was also performed. All patients are doing well, with no evidence of recurrence of fistula. CONCLUSIONS We advocate the right posterolateral thoracotomy route for the management of left-sided BPFs as an alternative to transternal transpericardial and transthoracic closures. It is a safe, feasible and time-efficient approach that provides control of central structures and avoids previously manipulated or infected operative fields.

Chest wall stabilization and reconstruction: short and long-term results 5 years after the introduction of a new titanium plates system

BACKGROUND We report short and long-term results with the dedicated Synthes(®) titanium plates system, introduced 5 years ago, for chest wall stabilization and reconstruction. METHODS We retrospectively analyzed (January 2010 to December 2014) 27 consecutive patients (22 males, 5 females; range 16-83 years, median age 60 years), treated with this system: primary [3] and secondary [8] chest wall tumor; flail chest [5]; multiple ribs fractures [5]; sternal dehiscence-diastasis [3]; sternal fracture [1]; sternoclavicular joint dislocation [1]; Poland syndrome [1]. Short-term results were evaluated as: operating time, post-operative morbidity, mortality, hospital stay; long-term results as: survival, plates-related morbidity, spirometric values, chest pain [measured with Verbal Rating Scale (VRS) and SF12 standard V1 questionnaire]. RESULTS Each patient received from 1 to 10 (median 2) titanium plates/splints; median operating time was 150 min (range: 115-430 min). Post-operative course: 15 patients (55.6%) uneventful, 10 (37%) minor complications, 2 (7.4%) major complications; no post-operative mortality. Median post-operative hospital stay was 13 days (range: 5-129 days). At a median follow-up of 20 months (range: 1-59 months), 21 patients (78%) were alive, 6 (22%) died. Three patients presented long-term plates-related morbidity: plates rupture [2], pin plate dislodgment [1]; two required a second surgical look. One-year from surgery median spirometric values were: FVC 3.31 L (90%), FEV1 2.46 L (78%), DLCO 20.9 mL/mmHg/min (76%). On 21 alive patients, 7 (33.3%) reported no pain (VRS score 0), 10 (47.6%) mild (score 2), 4 (19.1%) moderate (score 4), no-one severe (score >4); 15 (71.5%) reported none or mild, 6 (28.5%) moderate pain influencing quality of life. CONCLUSIONS An optimal chest wall stabilization and reconstruction was achieved with the Synthes(®) titanium plates system, with minimal morbidity, no post-operative mortality, acceptable operating time and post-operative hospital stay. Long-term restoration of a normal respiratory function was achieved, with minimal plates-related morbidity and chest pain.

Local Food Resources to Fight Children Malnutrition and Infectious Diseases in Mozambique

Objective: To develop sustainable recipes, using local food resources, as a possible solution to manage children malnutrition and nutritional lack in Mozambique, thus preventing infectious diseases. Methods: Our work was based on the Dietary Reference Intake (DRI) reports for children aged 4-8 years old. After having listed more than 60 commonly consumed local foods in Mozambique, we developed some recipes, indicating composition, energy and nutrients values. Information on nutrients concentrations was taken from the National Nutrient Database for Standard References, the Food Composition Tables for Mozambique and the Research Center for Aliments and Nutrition. In the recipes, the traditional way of listing ingredients was reported, which were then turned into international, standardized values. Results: We elaborated some different local food recipes, easy to prepare, at low cost and useful in a systematic approach in order to fight malnutrition in Sofala Province, Mozambique. Each recipe included functions and daily Recommended Dietary Allowance (RDA) of: water, proteins, lipids, carbohydrates, fibers, sodium, potassium, iron, calcium, phosphorus and vitamins. We suggested recipes richer in vitamins and micro/macro nutrients for breakfast, while those providing high caloric intake were more indicated for the main meal. The resulting recipes have been made understandable, for both local and international population, thanks to the coexistence of traditional and international description of ingredients. Conclusion: Local recipes approach is a possible promising tool among the most cost-effective/high impact interventions against child malnutrition and mortality from infectious diseases in Mozambique.

Pulmonary Infections of Surgical Interest in Childhood

Thoracic surgeons often treat children with infections: pneumonia with abscess and/or empyema, multiresistant or complicated tuberculosis, or parasitic and fungal infections. The pediatric patient with serious infection presents anatomic and metabolic-functional frailty. Anesthesiologists and surgeons must consider this aspect to reduce surgical impairment and improve outcome. This article reviews the causes, pathophysiology, clinical aspects, diagnosis, and management of pleuropulmonary infections of surgical interest in childhood.

Teenage pregnancies in Mozambique: the experience of “Servicios Amigos dos Adolescentes” clinics in Beira

The purpose of this article is to provide insights into the demand for pregnancy-related health services by adolescent girls and young women in Mozambique. We analysed the patient registers for the first year of operation (2014) of the Servicios Amigos dos Adolescentes (SAAJ) [Friendly Services for Adolescents] clinics in Beira, Mozambique. These registers provide details of the service demands of, and services provided to the 8 290 adolescent girls and young women who accessed the 6 SAAJ clinics in 2014. Analysis of that record, with disaggregation of the patients according to age (9 years or less; 10–14; 15–19; 20–24; 25 and older), show that 3 021 (36%) were pregnant or had previously been pregnant; most being girls in the 15–19 age band (59%). Being pregnant or having been pregnant previously was associated with dropping out of school. Of all the girls and women, 60% agreed to HIV testing and counselling; the HIV prevalence rate amongst this group was 4–5% amongst adolescents and 25% amongst women 25 years and older. A minority of the girls and women who were pregnant or had been pregnant previously agreed to HIV testing and counselling. Notwithstanding the limitations for analysis, the results were alarming: substantially high HIV prevalence rates were indicated (2% amongst 10–14 year old girls; 8% amongst 15–19 year olds; 10% amongst 20–24 year olds; and 28% amongst >24 year olds). The data from the SAAJ clinics and results pertain only to conditions in Beira. However, as the first empirical assessment of pregnancy-related service demand amongst adolescent girls and young women in the country and involving a relatively large sample, we contend that this study affirms the need for expansion of sexual and reproductive health (SRH) services, including HIV services, for adolescent girls and young women in Mozambique.
