Bronchoscopic treatment of pediatric atelectasis: A modified segmental insufflation-surfactant instillation technique.

BACKGROUND: Atelectasis is a condition characterized by the collapse and nonaeration of lung regions and is considered a manifestation of an underlying disease process. The goal of atelectasis treatment is the restoration of volume loss. In the range of different treatment options, chest physiotherapy is often used as a first-line approach, and some cases require bronchoscopic interventions. METHODS: In this case series, we describe a modified bronchoscopic treatment procedure using pressure-controlled bronchoscopic segmental insufflation with surfactant application. RESULTS: The proposed approach resulted in significant improvement of lung volume across a range of patients including massive lobar, atypical rounded atelectasis in previously healthy patients, and in a particularly challenging case involving an infant suffering from spinal muscular atrophy type I. CONCLUSION: The modified segmental insufflation-surfactant instillation technique offers a safe and promising easily implementable treatment of persistent atelectasis caused by different underlying disease processes with positive long-term outcomes.

Is there an increased incidence of orchiectomy in pediatric patients with acute testicular torsion during COVID-19 pandemic?-A retrospective multicenter study.

INTRODUCTION: Testicular torsion is a real emergency condition which requires prompt diagnosis and surgical management to prevent testicular loss. During the coronavirus (COVID-19) pandemic, an increased avoidance of the emergency departments for non-COVID-19 illnesses has been reported in the medical literature. OBJECTIVE: The aim of this study was to investigate whether the COVID-19 pandemic caused increased number of orchiectomies in pediatric patients presenting with acute testicular torsion compared to pre-COVID-19 period. STUDY DESIGN: A total number of 119 pediatric patients who underwent surgery for acute testicular torsion from January 2019 to December 2020 were enrolled in retrospective multi-center study from six institutions in Croatia. The patients were divided in two groups. The first group (pre-COVID-19) consisted of the patients who underwent surgery before COVID-19 pandemic (n = 68), while the second group (COVID-19) consisted of the patients who underwent surgery during the COVID-19 pandemic (n = 51). Main outcomes of the study were orchiectomy rates and time from onset of the symptoms to emergency department presentation. RESULTS: During the COVID-19 pandemic period 43.1% (22/51) of the patients underwent orchiectomy while orchiectomy was performed in 16.2% (11/68) of the patients from the pre-COVID group (p = 0.001). Median time from onset of the symptoms to emergency department presentation during COVID-19 pandemic and pre-COVID-19 periods was 14h (IQR 5, 48) and 6h (IQR 3, 22) (p = 0.007), respectively. A higher proportion of patients waited over 24 h to present to emergency department during the COVID-19 pandemic compared to the pre-COVID-19 period (47% vs 8.8%, p = 0.007). CONCLUSION: During COVID-19 pandemic a significantly higher rates of orchiectomies and increase in delayed presentations for testicular torsion was found. More patient education during pandemic in regards to management of emergency conditions such as testicular torsion is required.

Early Childhood Fat Tissue Changes-Adipocyte Morphometry, Collagen Deposition, and Expression of CD163+ Cells in Subcutaneous and Visceral Adipose Tissue of Male Children.

Childhood obesity is a complex health problem, and not many studies have been done on adipose tissue remodeling in early childhood. The aim of this study was to examine extracellular matrix remodeling in the adipose tissue of healthy male children depending on their weight status. Subcutaneous and visceral adipose tissue was obtained from 45 otherwise healthy male children who underwent elective surgery for hernia repairs or orchidopexy. The children were divided into overweight/obese (n = 17) or normal weight groups (n = 28) depending on their body mass index (BMI) z-score. Serum was obtained for glucose, testosterone, triglyceride, total cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) measurements. Sections of adipose tissue were stained with hematoxylin and eosin to determine the adipocytes' surface area, and Masson's trichrome stain was used to detect the adipocytes' collagen content. Immunohistochemistry for CD163+ cells was also performed. The results showed that male children in the overweight group had higher serum triglyceride levels, greater adipocyte surface area and collagen content in their subcutaneous adipose tissue, more crown-like structures in fat tissues, and more CD163+ cells in their visceral adipose tissue than males in the normal weight group. In conclusion, in male children, obesity can lead to the hypertrophy of adipocytes, increased collagen deposition in subcutaneous adipose tissues, and changes in the polarization and accumulation of macrophages.

Aggressive progression of Takayasu's arteritis in infancy: a case report.

Takayasu's arteritis (TA) affects the aorta and its branches. Immunosuppressants are the usual course of therapy, while surgery has been used in acute cases. There is only scant information on TA in infancy, and the nonspecific symptoms in the initial stage of the disease make the diagnosis difficult and delayed, thus increasing the mortality rate. We describe a case of aggressive progression of TA in an infant. This child was the youngest to be affected with the disease as reported in the literature. A 3.5-month-old boy presented with cyanosis of both legs, tachycardia and antithrombin III deficiency. Computed tomography angiography (CTA) revealed thrombosis of distal aorta and both iliac arteries. Thrombectomy was performed at the level of both common femoral arteries. In addition, thigh amputation of the left leg had to be performed. TA was diagnosed postmortem with thrombosis of the distal aorta, its branches and upper mesenteric artery which was not occluded on previous CTA, glomerulonephritis and pulmonary parenchymal granulomatous infiltrations.

Conservative surgical management of necrotic tissues following meningococcal sepsis: case report of a child treated with hyperbaric oxygen.

This article presents the case of a 5-month-old infant, who survived a fulminant meningococcal sepsis with purpura fulminans, septic shock and severe DIC with gastrointestinal bleeding. Amputation and reconstructive surgery were considered to treat the multiple skin and limb necroses at high risk of superinfection, but the surgical intervention was delayed due to the extremely doubtful outcome. On Day 10 after the onset of the disease, a hemodynamic improvement was achieved. The baby overcame early critical period, but was still in poor general condition. The hyperbaric oxygenation (HBO2) as adjuvant therapy was started in the monoplace chamber using the following protocol: from first through fifth day 45 minutes twice a day on 1.5 atmosphere absolute (ATA); after a two-day break, once a day on 1.8 ATA for 60 minutes. During 52 HBO2 treatments multiple areas of necrotic skin and subcutaneous tissue, together with fingertips and toes, detached spontaneously. All wounds healed without reinfections. An increased oxygen concentration during HBO2 therapy promoted spontaneous wound healing. Bacterial superinfection was not observed in numerous low-perfused lesions. Since repeated anesthesia and surgical interventions were not needed, a final invalidity was minimized. To the best of our knowledge, this is the first report on the successful conservative surgical treatment of this mutilating disease without aggressive reconstructive surgery in an infant with the help of HBO2.
