RESUMEN

AIM: To review and compare the incidence of juvenile onset recurrent respiratory papillomatosis (JRRP) at Starship Children's Hospital (SSH) before and after the introduction of a national HPV vaccination programme. METHODS: Patients treated for JRRP at SSH were identified retrospectively using ICD-10 code D14.1 over a 14-year period. The incidence of JRRP in the 10-year period prior to the introduction of HPV vaccination (1 September 1998 to 31 August 2008) was compared with the incidence after its introduction. A second comparison was made between the pre-vaccination incidence with the incidence over the most recent 6 years when the vaccination became more widely available. All New Zealand hospital ORL departments that referred children with JRRP to SSH exclusively were included. RESULTS: SSH manages about half of the New Zealand paediatric population with JRRP. The incidence of JRRP before the introduction of the HPV vaccination programme was 0.21 per 100,000 per year in children 14 years of age and younger. This remained stable between 2008 and 2022 (0.23 vs 0.21 per 100,000 per year). The mean incidence in the later post-vaccination period was 0.15 per 100,000 per year based on small numbers. CONCLUSION: The mean incidence of JRRP before and after the introduction of HPV has remained unchanged in children treated at SSH. More recently, a reduction in incidence has been noted, although this is based on small numbers. The low HPV vaccination rate (≤70%) may explain why a significant reduction in the incidence of JRRP seen overseas has not been observed in New Zealand. Ongoing surveillance and a national study would provide more insight into the true incidence and evolving trends.

RESUMEN

BACKGROUND: Late airway complications, as consequence of immunosuppression following pediatric liver transplantation are uncommonly reported. METHODS: In this retrospective case series, we describe two young children presenting with symptoms of airway obstruction, secondary to differing pathologies in the supraglottic airway, as a result of immunosuppression following liver transplantation. RESULTS: Case 1, a 2-year-old girl who presented with stridor 12-months following liver transplantation, was found to have a proliferative soft tissue mass involving the supraglottic larynx. Biopsies were consistent with infiltrative eosinophilic laryngitis and associated eosinophilic esophagitis. Case 2, a 12-month-old female who presented with stridor 5-months following liver transplantation, was found to have an exophytic soft tissue mass involving the supraglottis and hypopharynx. Biopsies revealed polymorphic Epstein-Barr virus (EBV) driven post-transplant lymphoproliferative disease (PTLD). Case 1 was managed with local resection and high dose oral corticosteroids. Case 2 responded to debulking of the necrotic supraglottic mass, reduction of immunosuppression and rituximab. CONCLUSION: A high index of suspicion needs to be maintained for complications of immunosuppression for appropriate diagnosis of airway presentations following pediatric liver transplantation. Further research is necessary to improve early detection and consolidate management strategies for these airway lesions.

RESUMEN

OBJECTIVE: To evaluate the learning curve of BiZact™ tonsillectomy amongst trainees and fellows as a further technical skill. METHODS: Prospective audit of consecutive BiZact™ tonsillectomies undertaken by a trainee and fellow at Starship Children's Hospital. Primary outcomes measured were operative time from gag open to gag closed, readmission and post tonsillectomy bleed rates. Secondary outcomes included need for bipolar rescue dissection, bipolar haemostasis including site and side, tonsil size (Brodsky grade 1-4) and depth (shallow or deep). Operative time was plotted against number of procedures performed and moving averages was used to investigate the learning curve. Generalised linear model was applied to examine the association between operation time and tonsil depth. RESULTS: Mean operative time for the trainee and fellow was similar (07 min 34 s versus 07min and 37 s). We observed a trend of decreased operative time over number of procedures performed by the trainee but the learning curve was short. The fellow's initial time was lower than the trainee's and remained similar over time. No bipolar rescue dissection was required. Additional bipolar haemostasis was required 95% of the time, but the majority involved the superior pole only (87.5%, p = 0.0001). The overall operative time for shallow tonsils was shorter than for deep tonsils (06 min 31 s versus 08 min 09 s, p = 0.0066). A learning curve was evident for both shallow and deep tonsils for both surgeons combined but was steeper for deep. There were no primary bleeds and the secondary haemorrhage rate was 5.8% (3/51 cases) with no returns to theatre. CONCLUSION: This is the first study to investigate the BiZact™ tonsillectomy learning curve. BiZact™ tonsillectomy is safe and easy to learn. We observed a clear trend of shallow tonsils being quicker to remove than deep tonsils using this technique. The secondary bleed rate of 5.8% is comparable to the previously published Starship rate of 4.7% for all tonsillectomies performed over a 10 year period. Moving averages is a useful method to assess operative learning curves during training and beyond.

RESUMEN

This national study quantifies procedural and surgical skills training at medical schools in the United Kingdom (UK), a stipulated requirement of all graduates by the General Medical Council (GMC). A questionnaire recorded basic procedural and surgical skills training provided by medical schools and surgical societies in the UK. Skills were extracted from (1) GMC Tomorrows Doctors and (2) The Royal College of Surgeons Intercollegiate Basic Surgical Skills (BSS) course. Data from medical school curricula and extra-curricular student surgical societies were compared against the national GMC guidelines and BSS course content. Data were analysed using Mann-Whitney U tests. Representatives from 23 medical schools completed the survey (71.9% response). Thirty one skills extracted from the BSS course were split into 5 categories, with skills content cross referenced against GMC documentation. Training of surgical skills by medical schools was as follows: Gowning and gloving (72.8%), handling instruments (29.4%), knot tying (17.4%), suturing (24.7%), other surgical techniques (4.3%). Surgical societies provided significantly more training of knot tying (64.4%, P = 0.0013) and suturing (64.5%, P = 0.0325) than medical schools. Medical schools provide minimal basic surgical skills training, partially supplemented by extracurricular student surgical societies. Our findings suggest senior medical students do not possess simple surgical and procedural skills. Newly qualified doctors are at risk of being unable to safely perform practical procedures, contradicting GMC Guidelines. We propose a National Undergraduate Curriculum in Surgery and Surgical Skills to equip newly qualified doctors with basic procedural skills to maximise patient safety.

RESUMEN

Undergraduate training in surgical safety is essential to maximize patient safety. This national review quantified undergraduate surgical safety training. Training of 2 international safety initiatives was quantified: (1) World Health Organization (WHO) "Guidelines for Safe Surgery" and (2) Department of Health (DoH) "Principles of the Productive Operating Theatre." Also, 13 additional safety skills were quantified. Data were analyzed using Mann-Whitney U tests. In all, 23 universities entered the study (71.9% response). Safety skills from WHO and DoH documents were formally taught in 4 UK medical schools (17.4%). Individual components of the documents were taught more frequently (47.6%). Half (50.9%) of the additional safety skills identified were taught. Surgical societies supplemented safety training, although the total amount of training provided was less than that in university curricula (P < .0001). Surgical safety training is inadequate in UK medical schools. To protect patients and maximize safety, a national undergraduate safety curriculum is recommended.

RESUMEN

BACKGROUND: Acute otitis media is very common, but diagnostic criteria and treatment recommendations vary considerably. METHODS: Medline, the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials were searched using the key words 'acute otitis media' AND 'diagnosis' OR 'diagnostic criteria' OR 'definition', and by combining the terms 'acute otitis media' AND 'guidelines'. PubMed was searched using the key words 'mastoiditis' and 'prevalence'. RESULTS: The 11 most recently published guidelines unanimously agreed that adequate analgesia should be prescribed in all cases. The majority recommended that routine antibiotic prescription should be avoided in mild to moderate cases and when there was diagnostic uncertainty in patients two years and older. Antibiotics were recommended in children two years and younger, most commonly a 5-day course of amoxicillin (or a macrolide in patients allergic to penicillin). CONCLUSION: Level 1A evidence shows that selected cases of acute otitis media benefit from antibiotic prescription.

RESUMEN

Tacrolimus (FK506) is a widely used immunosuppressant in organ transplantation. However, it also has neurotrophic activity that occurs independently of its immunosuppressive effects. Other neurotrophic immunophilin ligands that do not exhibit immunosuppression have subsequently been developed and studied in various models of nerve injury. This article reviews the literature on the use of tacrolimus and other immunophilin ligands in peripheral nerve, cranial nerve and spinal cord injuries. The most convincing evidence of enhanced nerve regeneration is seen with systemic administration of tacrolimus in peripheral nerve injury, although clinical use is limited due to its immunosuppressive side effects. Local tacrolimus delivery to the site of nerve repair in peripheral and cranial nerve injury is less effective but requires further investigation. Tacrolimus can enhance outcomes in nerve allograft reconstruction and accelerates reinnervation of complex functional allograft transplants. Other non-immunosuppressive immunophilins ligands such as V-10367 and FK1706 demonstrate enhanced neuroregeneration in the peripheral nervous system and CNS. Mixed results are found in the application of immunophilin ligands to treat spinal cord injury. Immunophilin ligands have great potential in the treatment of nerve injury, but further preclinical studies are necessary to permit translation into clinical trials.

RESUMEN

We present this unusual case of a 60-year-old gentleman who presented with meningism and reduced conscious level. Imaging demonstrated a perforated sigmoid colon with retroperitoneal air associated with pneumorrhachis and pneumocranium. He required a Hartmann's procedure and broad spectrum intra-thecal antibiotics which led to resolution of the pneumorrhachis and pneumocranium.

RESUMEN

Cholecystocolic fistula is a rare cause of diarrhoea, and the diagnosis may be significantly delayed. Air in the biliary tree on imaging should raise suspicion, and barium enema or endoscopic retrograde cholangiopancreatography will be diagnostic. Cholestyramine should provide effective symptomatic relief until definitive treatment is arranged. We report on two patients with cholecystocolic fistula presenting with severe diarrhoea. They were treated successfully by endoscopic retrograde cholangiopancreatography.
