<p class="abstract">Thyroglossal cyst is the most common congenital anterior neck swelling in childhood. Commonly present as painless swelling in the 2nd decade of life but the cases are reported in the elderly age group also. It represents the persistent epithelial tract from the foramen cecum to the thyroid gland. Clinically can be diagnosed and can be differentiated with other mid-line swelling by movement with the protusion of tongue. It is usually related to the hyoid bone and may be supra-hyoid, infra-hyoid, lower part of the midline or rarely lingual in position. Ultrasonography is the investigation of choice for this cystic condition. It is safe, economical and easily available investigation among all the radiological study. MRI is helpful to diagnose cervical extension and lingual cyst. Inspite of close relation to the laryngeal structure it rarely present as laryngeal mass and causes stridor or sleep apnea as in our case. Classic Sistrunk procedure is the treatment of choice for the condition. Endoscopic CO2 Laser is useful in situation where only intraoral cyst present without cervical extension. Marsupialization is reserved for lingual cyst especially in Neonate. We are reporting this case which was present in the elderly and reported with long standing anterior neck swelling with inspiratory stridor on lying down position.</p>

Objective. To determine the added clinical benefit of nebulized budesonide in children with mild to moderate croup treated with 0.6 mg/kg oral dexamethasone. Design. Randomized, double-blind, placebo-controlled trial. Setting. Emergency department of a tertiary-care pediatric hospital with 47 000 visits per year. Participants. Children 3 months to 5 years of age with a syndrome consisting of hoarseness, inspiratory stridor, and barking cough and a croup score of 3 or greater after at least 15 minutes of mist therapy. Patients were excluded from the study if they had diagnoses of epiglottitis, chronic upper or lower airway disease (not including asthma), or severe croup or had received corticosteroids within the preceding 2 weeks. Intervention. All patients received 0.6 mg/kg oral dexamethasone and were randomly assigned to receive 4 mL (2 mg) of budesonide solution (n = 25) or 4 mL of 0.9% saline solution (n = 25) by updraft nebulizer with a continuous flow of oxygen at 5 to 6 L/min. Main Outcome Measures. The primary outcome measure was the proportion of patients in each group who had clinically important changes (two points) in the croup score during the 4 hours after treatment. Results. Eighty-four percent (n = 21) of the patients who received budesonide had clinically important responses, compared with 56% (n = 14) in the placebo group. The number of patients who would need to be treated with nebulized budesonide for one patient to have a clinically important response is four patients. Conclusions. Despite receiving simultaneous oral dexamethasone, pediatric outpatients with mild to moderate croup have added, clinically important improvement in respiratory symptoms after treatment with budesonide.

Laryngeal Involvement

In 1970, Perrone1 first reported laryngeal obstruction secondary to Candida albicans infection in a newborn. There have been several descriptions of congenital or neonatal infection with C albicans including pustubar dermatitis,2 pneumonia,3 meningitis, and arthritis.4 However, none of these reports noted laryngeal involvement. Recently, laryngitis and esophagitis were described in children with chronic mucocutaneous candidiasis.5 Adult patients predisposed to invasive candidal infections have had laryngeal involvement; on occasion their initial symptoms were those of upper airway obstruction.6 Infants and newborns with inspiratory stridor are usually evaluated for laryngomalacia, congenital subglottic stenosis, or vocal cord paralysis. Candidal laryngitis presenting as inspiratory stridor has not been well documented in the pediatric literature.

The development of the replacement transfusion for the prevention of brain damage associated with elevated levels of bilirubin in the blood has prompted numerous papers related to this procedure. The present report deals with a frequently observed phenomenon occurring during exchange transfusion, which seldom attracts attention until a disastrous episode takes place. This was our experience, and it therefore seemed desirable to re-evaluate the pathophysiology associated with pressure changes in the umbilical vein of the neonate. This report will present a case of marked negative pressure in the umbilical vein of a neonate exhibiting inspiratory stridor of partial airway obstruction, and also the physiologic data from some animal experi ments to demonstrate this phenomenon. CASE REPORT Infant B was the second-born, male twin of a 24-year-old, Rh-negative, gravida 4, para 3 mother. At term the maternal Rh antibody titer was 1:32. The membranes ruptured spontaneously 48 hours prior to delivery. Labor was induced with oxytocin (Pitocin) administered intravenously. Twin Infant A was delivered spontaneously, unassisted; it was then found that twin B presented as a "transverse lie." This second twin was delivered in 15 minutes by version and extraction. Respiration was initiated after endotracheal aspiration and was normal for 1 hour, after which an inspiratory stridor was noted associated with moderate cyanosis. The stridor and cyanosis improved with oxygen-mist therapy. The baby weighed 2,930 gm and the blood was Rh-positive and Coombs' positive, as was the blood of his twin. Bilirubin in the serum at birth was 3 mg/100 ml; hemoglobin, 14.5 gm/100 ml.

Background and objectiveThe differential diagnosis for exercise-associated breathlessness is broad, however, when a young athletic individual presents with respiratory symptoms, they are most often prescribed inhaler therapy for presumed exercise-induced asthma (EIA). The purpose of this study was therefore to use a novel sound-based approach to assessment to evaluate the prevalence of exertional respiratory symptoms and characterise abnormal breathing sounds in a large cohort of recreationally active individuals.MethodsCross-sectional field-based evaluation of individuals completing Parkrun.Phase 1Prerace, clinical assessment and baseline spirometry were conducted. At peak exercise and immediately postrace, breathing was monitored continuously using a smartphone. Recordings were analysed retrospectively and coded for signs of the predominant respiratory noise.Phase 2A subpopulation that reported symptoms with at least one audible sign of respiratory dysfunction was randomly selected and invited to attend the laboratory on a separate occasion to undergo objective clinical workup to confirm or refute EIA.ResultsForty-eight participants (22.6%) had at least one audible sign of respiratory dysfunction; inspiratory stridor (9.9%), expiratory wheeze (3.3%), combined stridor+wheeze (3.3%), cough (6.1%). Over one-third of the cohort (38.2%) were classified as symptomatic. Ten individuals attended a follow-up appointment, however, only one had objective evidence of EIA.ConclusionsThe most common audible sign, detected in approximately 1 in 10 individuals, was inspiratory stridor, a characteristic feature of upper airway closure occurring during exercise. Further work is now required to further validate the precision and feasibility of this diagnostic approach in cohorts reporting exertional breathing difficulty.

A two-year-old working Belgian shepherd dog was referred for diagnosis and management of a chronic cough, exercise intolerance and inspiratory stridor. A diagnosis of severe dorsal tracheal membrane redundancy was made based on radiography and tracheoscopy. Vomiting, weight loss and lethargy were also reported at initial presentation presumed secondary to dietary indiscretion, which was supported by the identification of undigested bones in the stomach on radiographs and ultrasound; these signs resolved with symptomatic treatment. The patient had previously been diagnosed with primary immune-mediated polyarthritis and had responded well to immunomodulatory medication. To correct the narrowing of the tracheal lumen, the dorsal tracheal membrane was plicated surgically, improving the tracheal diameter postoperatively. Twelve weeks later the dog had returned to full exercise, and the handler reported excellent exercise tolerance and no cough. Plication of excessive dorsal tracheal membrane is one possible treatment option for dogs with severe dorsal tracheal membrane redundancy.

Hypoxanthine Guanine Phosphoribosyl Transferase

Lesch-Nyhan disease (LND) is an X-linked recessive disorder caused by a deficiency in hypoxanthine-guanine phosphoribosyl transferase. Patients with LND experience involuntary movements, including dystonia, choreoathetosis, opisthotonos, ballismus, and self-injury. Alleviating these involuntary movements is important to improve the quality of life in patients with LND. Many clinicians have difficulty controlling these involuntary movements in their patients, and there are no established and effective treatments. A 6-month-old boy with LND presented with generalized dystonia and self-injury behavior that was alleviated after receiving S-adenosylmethionine (SAMe). His self-injury behavior completely resolved after he received SAMe and risperidone. Although he had often experienced inspiratory stridor because of laryngeal dystonia and frequently developed aspiration pneumonitis and bronchitis, no inspiratory stridor was noted after SAMe treatment. The patient is continuing to receive SAMe and risperidone. SAMe treatment alleviates dystonic movements and improves quality of life in pediatric patients with LND. Additional research is needed to determine the long-term safety and efficacy of SAMe and its appropriate dosage.
