Prevalence and characterisation of exercise-induced laryngeal obstruction in patients with exercise-induced dyspnoea.

OBJECTIVE: The prevalence of exercise-induced laryngeal obstruction is largely unknown. This study aimed to evaluate the prevalence of this condition in a selected study population of patients with exercise-induced dyspnoea. METHOD: A retrospective analysis was conducted of demographic data, co-morbidities, medication, symptoms, performance level of sporting activities, continuous laryngoscopy exercise test results and subsequent treatment. RESULTS: Data from 184 patients were analysed. The overall prevalence of exercise-induced laryngeal obstruction in the study population was 40 per cent, and the highest prevalence was among females aged under 18 years (61 per cent). However, a high prevalence among males aged under 18 years (50 per cent) and among adults regardless of gender (34 per cent) was also found. CONCLUSION: The prevalence of exercise-induced laryngeal obstruction is clinically relevant regardless of age and gender. Clinicians are encouraged to consider exercise-induced laryngeal obstruction as a possible diagnosis in patients suffering from exercise-induced respiratory symptoms. No single characteristic that can distinguish exercise-induced laryngeal obstruction from other similar conditions was identified.

Risk of hematoma after hemithyroidectomy in an outpatient setting: a systematic review and meta-analysis.

PURPOSE: After thyroid surgery, the overriding concern is the risk of post-thyroid bleeding (PTB). This systematic review and meta-analysis aimed to assess the safety of hemithyroidectomy in an outpatient setting compared to an inpatient setting. The objectives were to (1) find the proportion of PTB in patients scheduled for outpatient hemithyroidectomy, (2) examine if outpatient hemithyroidectomy is clinically safe compared to an inpatient setting and (3) evaluate which selection criteria are most relevant for hemithyroidectomy in an outpatient setting. METHODS: A systematic review was conducted using the following databases: MEDLINE (Ovid), EMBASE (Ovid) and the Cochrane Library from inception until September 2021. We included studies reporting on PTB of patients after hemithyroidectomy in an outpatient setting. The risk of bias was assessed using the Newcastle-Ottawa tool. The results were synthesised using Bayesian meta-analysis. Certainty in evidence was assessed using the GRADE approach. RESULTS: This review included 11 cohort studies and 9 descriptive studies reporting solely on outpatients resulting in a total of 46,866 patients. PTB was experienced by 58 of the 9025 outpatients (0.6%) and 415 of the 37,841 inpatients (1.1%). There was no difference between the PTB rate of outpatients and inpatients (RR 0.715 CrI [0.396-1.243]). The certainty of the evidence was very low due to the high risk of bias. CONCLUSION: The risk of PTB in an outpatient setting is very low, and outpatient hemithyroidectomy should be considered clinically safe. The most relevant selection criteria to consider in outpatient hemithyroidectomy are (1) relevant comorbidities and (2) psycho/-social factors.

Outpatient hemithyroidectomy for benign thyroid disease.

INTRODUCTION: Hemithyroidectomy for benign thyroid disease has traditionally been considered an inpatient procedure due to concerns about post-operative complications, in particular the risk of post-thyroidectomy bleeding (PTB). Hemithyroidectomy in an outpatient setting has not yet been evaluated in a Danish context. This study aimed to evaluate outpatient compared to inpatient hemithyroidectomy in selected patients (no suspicion of malignancy, lesser-than 100 ml lobe, American Society of Anesthesiologists class I or II and no anticoagulation therapy) to investigate the safety of the procedure. METHODS: This cohort study was conducted between June 2014 and June 2019 in a Danish regional hospital and included all hemithyroidectomy patients. Data were obtained retrospectively from medical records. The primary outcome was PTB, and secondary outcomes included nerve injury, infection, perioperative drain placement, reintervention and unplanned hospital contacts. RESULTS: Hemithyroidectomy was performed in 229 patients. For 137 patients, the procedure was planned in an outpatient setting; and among these, 124 patients (91%) were completed as planned. None of the patients in either the outpatient or inpatient setting experienced PTB. In the outpatient group, 1.5% had permanent nerve injury of the recurrent nerve and 0.7% had a superficial wound infection which was treated with oral antibiotics. CONCLUSIONS: Hemithyroidectomy for benign thyroid disease is safe to perform in an outpatient setting for a selected patient group. FUNDING: none. TRIAL REGISTRATION: not relevant.

A Scandcleft randomised trials of primary surgery for unilateral cleft lip and palate: 1. Planning and management.

BACKGROUND AND AIMS: Longstanding uncertainty surrounds the selection of surgical protocols for the closure of unilateral cleft lip and palate, and randomised trials have only rarely been performed. This paper is an introduction to three randomised trials of primary surgery for children born with complete unilateral cleft lip and palate (UCLP). It presents the protocol developed for the trials in CONSORT format, and describes the management structure that was developed to achieve the long-term engagement and commitment required to complete the project. METHOD: Ten established national or regional cleft centres participated. Lip and soft palate closure at 3-4 months, and hard palate closure at 12 months served as a common method in each trial. Trial 1 compared this with hard palate closure at 36 months. Trial 2 compared it with lip closure at 3-4 months and hard and soft palate closure at 12 months. Trial 3 compared it with lip and hard palate closure at 3-4 months and soft palate closure at 12 months. The primary outcomes were speech and dentofacial development, with a series of perioperative and longer-term secondary outcomes. RESULTS: Recruitment of 448 infants took place over a 9-year period, with 99.8% subsequent retention at 5 years. CONCLUSION: The series of reports that follow this introductory paper include comparisons at age 5 of surgical outcomes, speech outcomes, measures of dentofacial development and appearance, and parental satisfaction. The outcomes recorded and the numbers analysed for each outcome and time point are described in the series. TRIAL REGISTRATION: ISRCTN29932826.

Scandcleft randomised trials of primary surgery for unilateral cleft lip and palate: 3. Descriptive study of postoperative nursing care following first stage cleft closure.

BACKGROUND: Cleft lip and palate is one of the most common congenital anomalies requiring surgical treatment in children, normally commenced in the first year of life. Following the initiation of a group of multicentre surgical trials of primary surgery, variations in postoperative recovery and management became apparent. An agreement was made for a nurse-led survey in eight surgical centres to document postoperative care and recovery. MATERIALS AND METHODS: A postoperative recovery clinical report form was developed to capture relevant data for the children participating in the four arms of the trials. This included the age and weight at admission, the postoperative recovery setting, pain management, postoperative feeding, post-operative complications, and length of hospital stay. RESULTS: Four hundred and three nursing forms from the first surgical procedure were returned for analysis. Differences in important aspects of care such as postoperative analgesia and postoperative feeding were evident. Postoperative care was influenced by local custom and practice, as little firm clinical evidence exists to guide optimal management. CONCLUSION: Postoperative recovery may play a significant role in the future selection of surgical protocols, and future trials need to consider cross-study site training to familiarise nurses, prior to any changes in surgical methods.
