Fatal COVID-19 in a neonate after probable late intrauterine transmission.

We report the case of a 35-week gestation infant girl born by emergent cesarean section for fetal distress in a woman with recent coronavirus disease 2019 (COVID-19). Tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using polymerase chain reaction (PCR) on the infant at 24 and 48 hours of life were negative. However, at 72 hours of life, the infant's respiratory status worsened, and a repeat SARS-CoV-2 PCR was positive.

Efficacy of Levetiracetam and Phenobarbital as First-Line Treatment for Neonatal Seizures.

High neonatal seizure burden is associated with worsened neurodevelopmental outcomes. We compared the efficacy of initial treatment with levetiracetam vs phenobarbital for maintaining low seizure burden in a retrospective cohort of 25 neonates monitored with video electroencephalography (EEG). Video EEG tracing were reviewed and paired with medication bolus times to determine seizure burden after treatment.

[Rhinosurgery in children: developmental and surgical aspects of the growing nose].

The anatomy of the nasal skeleton in newborns and adults are not alike. The complete cartilaginous framework of the neonatal nose becomes partly and gradually ossified during the years of growth and is more vulnerable to trauma in that period. Injury in the early youth may have large consequences for development of a nasal deformity which will increase during growth and reach its peak during and after the adolescent growth spurt.

Pediatric otorhinolaryngology anno 2008: towards European standards for training?

The Union Européen des Médecins Spécialistes (UEMS) has been promoting harmonization of specialist training programs in Europe. Anticipating a future contribution to a European standard for training specialists for tertiary care of children with otorhinolaryngology (ORL)-related problems this Round Table was organized by ESPO. The presentations refer to six European countries.

Rhinosurgery in children: basic concepts.

In newborns, the main supporting structure of the nose is the dorsoseptal cartilage, a T-bar-formed complex of septum and upper lateral cartilages, which is essentially an external extension of the cartilage of the anterior cranial base. Later the anatomic situation gradually changes -- a potential pitfall for surgeons and radiologists. The vulnerability of various processes underlying postnatal development of the facial skeleton is discussed.

Quality of life during the first 3 months following discharge after surgery for head and neck cancer: prospective evaluation.

Objective: To identify patient groups that are prone to poorer quality of life (QoL) during the first 3 months following discharge from the hospital after surgery for head and neck cancer.

Design: Prospective evaluation of the QoL of surgically treated head and neck cancer patients measured with questionnaires at discharge and at 6 weeks and 3 months after discharge.

Setting: Department of Otolaryngology and Head and Neck Surgery of the Erasmus University Medical Centre, a tertiary health care centre in Rotterdam, The Netherlands.

Impact on quality of life of a telemedicine system supporting head and neck cancer patients: a controlled trial during the postoperative period at home.

Objectives: Telemedicine applications carry the potential to enhance the quality of life of patients, but studies evaluating telemedicine applications are still scarce. The evidence regarding the effectiveness of telemedicine is limited and not yet conclusive. This study investigated whether telemedicine could be beneficial to the quality of life of cancer patients.

Involving the patient: a prospective study on use, appreciation and effectiveness of an information system in head and neck cancer care.

Objective: To determine use, appreciation and effectiveness of an electronic health information support system in head and neck (H&N) cancer care.

Design: A prospective evaluation study. The evaluated system has four different functions: (1) communication amongst health care providers and between health care providers and patients, (2) information for health care providers and patients, (3) contact with fellow sufferers and (4) monitoring of discharged patients by means of electronic questionnaires.

Intrinsic and extrinsic forces determine the distortion of the split cricoid ring.

Objective: An anterior cricoid split (ACS) causes an immediate distortion of the cricoid cartilage resulting in an anterior gap due to retraction of the cut ends. The objective of this animal study is to investigate: (1) to what extent the distortion after ACS is influenced by non-cartilaginous structures like tunica elastica, membranes, ligaments and muscles, which are connected to the cricoid; (2) how distortion is changing with further development; (3) in what way the distortion is affected by scoring of the internal surface of the cricoid; and (4) whether an immediate or late injury-induced distortion is related to age.

Methods: Surgical interventions were performed in 20 young (8 weeks of age, 1300-1600 g) and 5 adult (28 weeks of age, 3500-4000 g) New Zealand White rabbits.

Controlling incision-induced distortion of nasal septal cartilage: a model to predict the effect of scoring of rabbit septa.

Cartilage can be shaped by scoring. In an exploratory study in living adult animals, this phenomenon was demonstrated in cartilage of the nasal septum. Bending was observed immediately after superficial scoring of the cartilage surface, and the cartilage always warped in the direction away from the scored side.

An information system to support the care for head and neck cancer patients.

The potential of Information and communication technology (ICT) as a method to improve care is widely acknowledged. However, before ICT can be used in a specific patient population, the needs of that population must first be made explicit. In this paper we aim to explore the feasibility and functionality of an electronic information system to support head and neck (H&N) cancer care.

Surgery of the lateral nasal wall and ethmoid: effects on sinonasal growth: an experimental study in rabbits.

Objective: To assess the impact of lateral nasal wall surgery on sinonasal growth

Methods: Twenty young New Zealand White rabbits, 6 weeks of age, were included in this experimental study. Surgery was performed on two groups of ten animals each (series I and II). Entrance to the left nasal cavity is achieved through the nasal dorsum via mobilization and rotation of the left nasal bone.

The dual role of perichondrium in cartilage wound healing.

Cartilage structures from the head and neck possess a certain but limited capacity to heal after injury. This capacity is accredited to the perichondrium. In this study, the role of the inner (cambium) and the outer (fibrous) layers of the perichondrium in cartilage wound healing in vitro is investigated.

Subglottic stenosis after endolaryngeal intubation in infants and children: result of wound healing processes.

Objective: To study the histopathology of subglottic stenosis in children of different ages after treatment during different periods of time, with or without laser application. Partial resection of the anterior cricoid with adhering stenotic subglottic area in the live young patient provides unique material for studying wound healing and scarring processes.

Methods: 25 specimens obtained from partial cricotracheal resection (PCTR) in children, were histologically processed and stained with Haematoxylin and Eosin, Resorcin and Fuchsin (for elastic fibers), and immunohistochemical staining (for the presence of macrophages).

A new in vivo model for testing cartilage grafts and biomaterials: the 'rabbit pinna punch-hole' model.

In this study an animal model was developed for evaluation of the feasibility of cartilage grafts. In the cartilage of the external ear of the rabbit multiple holes, 6 mm in diameter, were punched, leaving the adherent skin intact. Different experimental groups were evaluated.

Pediatric otorhinolaryngology in Europe.

Nowadays Europe encompasses more than 30 countries. These countries differ in climate, in culture, in population density, in history, in socio-economic system and in the organization of medical care. Despite these differences there is a general trend of unification in politics, in industry and in science.

Psychosocial and physical correlates of survival and recurrence in patients with head and neck carcinoma: results of a 6-year longitudinal study.

Background: Studies that have examined correlations between psychosocial factors and survival in cancer patients do not permit any definitive conclusions. To the authors' knowledge, to date no study has examined the relation between medical as well as quality of life variables and survival in head and neck carcinoma patients. The current study focused on the complex interactions among psychosocial, medical, behavioral, and demographic variables as they relate to prognosis in these patients.

Efficacy of perichondrium and a trabecular demineralized bone matrix for generating cartilage.

A pedicled auricular perichondrial flap wrapped around trabecular demineralized bovine bone matrix can generate an autologous cartilage graft. In earlier experimental studies, it was demonstrated that this graft could be used for nasal and cricoid reconstruction. It was assumed that the vascularization of the perichondrial flap was obligatory, but it was never proven that the flap should be pedicled.

Management of infantile subglottic hemangioma: laser vaporization, submucous resection, intubation, or intralesional steroids?

The infantile subglottic hemangioma can be treated in various ways. The results of the treatment used in the Sophia Children's Hospital, intralesional steroids and intubation (IS + I), are discussed and compared with the results of other current treatment methods: CO2 laser vaporization, submucous resection and intubation alone. A total of 18 infants were treated for subglottic hemangioma in our hospital: ten with IS + I alone, five were first treated with systemic therapy and later with IS + I alone and three with various therapies.

Wound healing of cartilage structures in the head and neck region.

This study was performed to determine the various processes involved in the behaviour of hyaline cartilage during the wound healing period after trauma or surgery of vulnerable structures like the nasal septal cartilage and the cricoid. The results of different procedures (perpendicular and parallel to the cartilage surface) in young and young-adult animals were analyzed: septal incision at different locations (young-old), cricoid split (young-old), suturing cartilage, closing defects with autologous cartilage (young), biomaterials (young) and newly engineered cartilage in 4- and 24-week-old rabbits (series of ten animals). Cartilage of the young rabbit and child have similar hyaline cartilage with a varying distribution in thickness.

The immediate effects of local trauma on the shape of the cricoid cartilage.

Injury-induced abnormal development of the cricoid ring has been demonstrated in previous growth studies. In this study we focused on the immediate effects of various types of lesions to the cricoid, eliminating the influence of inserting muscles. In isolated, vital cricoids (cricoid explants) the anterior arch was split, creating a small gap between the cut ends.
