Salil Sood, Ian Street, Adam Donne
Hoarseness or dysphonia are terms used to describe a change in the quality of the voice. The voice quality can be raspy, breathy, strained, fatigued, rough, tremulous or weak. There may be a change in pitch, restriction of range, voice breaks, decreased projection, or abnormal resonance. It is important to remember that a voice disorder is not a disease in itself but rather a presentation of an underlying pathology. Clinicians' knowledge of paediatric hoarseness is limited as it can be difficult to examine children using fibreoptic laryngoscopy and the child may not comprehend the need for detailed examination...

BACKGROUND: Videolaryngoscopy is a valuable technique for endotracheal intubation. When used in the perioperative period, different videolaryngoscopes vary both in terms of technical use and intubation success rates. However, in the prehospital environment, the relative performance of different videolaryngoscopic systems is less well studied. METHODS: We conducted this prospective, randomized, multicenter study at 4 German prehospital emergency medicine centers...

The incidence of congenital stridor is on rise due to improved neonate and infant survival rate. The gold standard investigation for evaluation of stridor is rigid laryngotracheobronchoscopy, but this is invasive and requires general anesthesia. Flexible fibreoptic laryngoscopy, a relatively simple and less invasive procedure can be done under topical anaesthesia for evaluation of stridor. In this study, we have presented our experience of flexible laryngoscopy in children with congenital stridor, their results and management...

Myxomas are rare in the vocal cords. A 69-year-old man was admitted with one-year history of progressive dysphonia. Laryngoscopy revealed a polypoid mass on the right vocal cord. The diagnosis was cellular myxoma. A review of the literature including the present case revealed eleven reported cases of myxoma. Ten cases were classic myxoma. To the best of our knowledge, cellular myxoma has not been previously reported in the vocal cord. Hypercellularity does not affect the behavior of cellular myxoma. However, its recognition is important to prevent confusion with the group of low-grade myxoid sarcomas...

BACKGROUND: Preeclampsia is associated with greater narrowing of the airway than normal pregnancy, but it is not known if these changes worsen during labor and delivery. The aim of the study was to evaluate the airway during and after labor in women with or without preeclampsia. METHODS: Twenty-five normal and 25 severely preeclamptic pregnant women in early labor were recruited in this single-center, prospective, case-control study. Airway assessment was performed (a) before active labor (b) within one hour of delivery and (c) 24-48 h postpartum...

Background and Aims: Haemodynamic responses to laryngoscopy and endotracheal intubation and their hazards are well documented. The purpose of the study was to compare the effects of laryngoscopy and intubation on cardiovascular responses when the appropriate moment for intubation was directed by either clinical judgment or train-of-four assessment. Methods: A total of 68 patients, posted for laparoscopic cholecystectomy, were randomised into two groups. In Group M patients, the trachea was intubated after train of four counts became zero in adductor pollicis muscle, whereas in Group C patients, the trachea was intubated after the clinical judgment of jaw muscle relaxation...

Background and Aims: Apnoeic oxygenation during laryngoscopy has been emphasised in recent recommendations for airway management. We aimed to compare the effect of nasal oxygen supplementation on time for pulse oximeter oxygen saturation (SpO2) to fall from 100% to 92% (desaturation safety time), to assess the arterial oxygen partial pressures (PaO2) with and without nasal oxygen supplementation and the time for SpO2 to recover from 92% to 100% after initiation of ventilation. Methods: This is a prospective randomised placebo-controlled trial involving sixty patients, where nasal oxygen supplementation given at 10 L/min during apnoea of laryngoscopy in one group of patients (Group O2) was compared to no oxygen supplementation in other group (Group NoO2)...

REVIEW
S R Tasbihgou, M F Vogels, A R Absalom
Unintended accidental awareness during general anaesthesia represents failure of successful anaesthesia, and so has been the subject of numerous studies during the past decades. As return to consciousness is both difficult to describe and identify, the reported incidence rates vary widely. Similarly, a wide range of techniques have been employed to identify cases of accidental awareness. Studies which have used the isolated forearm technique to identify responsiveness to command during intended anaesthesia have shown remarkably high incidences of awareness...

Case summary: An 8-year-old female spayed Siamese indoor cat presented with a 3 week history of inspiratory dyspnoea, stridor and open-mouth breathing after exercise. Laryngoscopy, tracheoscopy, bronchoscopy and retroflexed nasopharyngoscopy were performed, and identified a multilobulated intraluminal mass within the trachea. Brush cytology was performed on the mass but was inconclusive in providing a definitive diagnosis. A CT scan of the neck failed to identify an obvious intraluminal mass and was negative to contrast uptake...

Background: Lymphoepithelial carcinoma is a tumor mostly diagnosed in the nasopharynx, but it has also been described in a variety of nonnasopharyngeal sites. It is extremely rare in the larynx and should be distinguished from squamous cell carcinoma. Therefore, it must be known by clinicians, pathologists and oncologists. In this case report, we discuss its etiopathogeny, its epidemiological, clinical, pathological and therapeutic aspects, and its outcome. Case presentation: An 81-year-old Morrocan man, smoker for 40 years, presented with a 1 year history of dysphonia, dyspnea and dysphagia...
