Atypical granular cell tumour in a child: A rare case report.

We report an atypical granular cell tumour (GCT) presenting in a 6-year-old boy. GCTs are of neural origin and most cases arise in patients between the ages of 40 and 60. There are few reported cases in children, in whom malignant presentations are exceptionally rare. This patient presented with a 1 year history of a slowly enlarging nodule on the right anterior abdomen. Examination revealed a firm, nodular dermal skin lesion, which was fully excised. Histology revealed an atypical GCT.

A retrospective analysis of speech and hearing in patients receiving surgery for submucous cleft palate.

Submucous cleft palate (SMCP) is an uncommon subtype of cleft palate that is associated with symptoms of velopharyngeal insufficiency (VPI), the most common being hypernasal speech. A high proportion of patients also suffer from conductive hearing loss, which is thought to be due to eustachian tube dysfunction. A number of surgical techniques have been proposed to correct the anatomical defect that is responsible for VPI. This exploratory study aims to describe surgical techniques and clinical outcomes in a series of patients who underwent surgical repair of SMCP at a single regional specialist cleft centre between 1999 and 2018. Through a retrospective case note review, records of 57 patients who underwent SMCP repair between the ages of 6 months and 16 years were examined. Patients underwent one of the three surgical techniques: Intravelar Veloplasty, Furlow or a novel technique we have termed as "Hemi-Furlow". Hypernasality, measured on the Great Ormond Street Speech Assessment, showed evidence of improvement post-operatively in all three surgical groups (P<0.005), with no evidence to favour any specific approach. Post-operative complications, including wound dehiscence and fistulae, occurred in nine patients (15.8%). Nine patients (15.8%) required revisional surgery, either due to post-operative complications or persistent speech problems. Otological disease was present in 54.4% of patients, comprising conductive hearing loss due to otitis media with effusion (52.6%) and sensorineural hearing loss (1.8%). There is now a need for large, multi-centre studies with robust outcomes measures to further examine relationships between surgical techniques and clinical outcomes in people born with SMCP.

The impact of COVID-19 on cleft services in Great Britain & Northern Ireland.

INTRODUCTION: Cleft lip and/or palate is the most common craniofacial anomaly and occurs in 1 in 650 to 700 live births in the United Kingdom (UK). The majority of cleft surgery is elective, and as a result, almost all cleft surgery was suspended across the UK in March 2020 during the first national lockdown. The UK has centralised regional Cleft Services which all use the same agreed target-age standards for primary surgery including lip and palate repairs. The coronavirus disease-2019 (COVID-19) response has caused a delay in carrying out procedures. The severity of this delay depends on the impact of COVID-19 on local trusts and R-value within that region. As the country goes through the second and third wave, the impact could be long lasting, and we aimed to quantify it so that the data could be used to guide service prioritisation in the NHS and help future workforce planning. METHODS: An online survey was designed based on the cleft quality dashboard indicators and circulated nationally to all nine cleft regions in the UK. The survey was divided into three main headings: • Duration of suspended cleft services • Quantification of the impact on delayed in surgery/services • Changes needed to restart surgery/services RESULTS: We obtained a 60% response rate with five completed surveys from five out of nine regions. All regions reported that they suspended their cleft services in March 2020 around the time of the first wave and the first national lockdown. There has been an impact on delayed surgical and clinical interventions for cleft patients. Regions were affected differently with some on an exponential waiting list growth projection, whereas other teams are on track to recover from the backlog within 7-22 weeks. There has been an impact on the allied health professionals' services within the cleft multidisciplinary team. The cleft nurses' 24-h reviews, Speech And Language Therapy (SALT), and psychology maintained service delivery in some format. Patient-facing services such as audiology and dentistry were significantly disrupted and continue to experience delays due to reduced capacity. CONCLUSIONS: Various regions have seen a varied impact from COVID-19 on their services, from all cleft regions there seems to be an impact on achieving surgery within the national target age. The adverse effect of the COVID-19 impact is unlikely to be known for a few years to come; however, the data are a useful guide when supporting the allocation of resources within the healthcare setting. A prospective long-term study is required to assess the impact of COVID-19 on cleft surgery, follow-up, assess access to allied health professional MDT clinics, and long-term complications.

Splinting After Ear Reconstruction: A Stepwise and Inexpensive Workflow Protocol.

BACKGROUND: Long-term postoperative splinting plays a role in the prevention of contracture of the grafted skin after a second-stage ear reconstruction. The scar retraction could lead to an unfavorable aesthetic outcome. Splinting could play a role to overcome or prevent the loss of projection and the obliteration of the sulcus. MATERIAL AND METHODS: We have defined the characteristics of an ideal long-term splint and present a stepwise clinical protocol for the fabrication of an ethylene-vinyl acetate splint. The splint was applied to all patients included in a prospective study on the postoperative splinting regime. Ethylene-vinyl acetate has proved its safety and longevity in dental prosthetics. CONCLUSIONS: Patient compliance was optimal, and no allergic reactions, pressure sores, or skin necrosis were reported. The splint is self-retaining and light weight. Because of its transparent color, it can be easily camouflaged. A stepwise clinical protocol for the fabrication of a low-cost patient-specific ear splint is presented.

Successful Deep Inferior Epigastric Perforator Flap Harvest despite Preoperative Therapeutic Subcutaneous Heparin Administration into the Abdominal Pannus.

Abdominal free flaps for microsurgical breast reconstruction are most commonly harvested based on the deep inferior epigastric vessels that supply skin and fat via perforators through the rectus muscle and sheath. Intact perforator anatomy and connections are vital for subsequent optimal flap perfusion and avoidance of necrosis, be it partial or total. The intraflap vessels are delicate and easily damaged and it is generally advised that patients should avoid heparin injection into the abdominal pannus preoperatively as this may compromise the vascular perforators through direct needle laceration, pressure from bruising, haematoma formation, or perforator thrombosis secondary to external compression. We report three cases of successful deep inferior epigastric perforator (DIEP) flap harvest despite patients injecting therapeutic doses of low molecular weight heparin into their abdomens for thrombosed central venous lines (portacaths™) used for administering primary chemotherapy in breast cancer.

Please close this skin wound.

Acute cutaneous wounds following trauma are commonly encountered in the emergency department. This article explains the principles of their closure and provides advice on optimal management. Wound healing occurs in four phases: haemostatic, inflammatory, proliferative and maturation (Janis et al, 2010). The guidance below is based on the authors' personal practice, designed to promote transition through these stages and result in optimized healing with minimal scarring. It is intended to guide the reader through what can be a daunting prospect for many doctors in training: the acute closure of simple wounds.

Inflammatory bowel disease in CGD reproduces the clinicopathological features of Crohn's disease.

OBJECTIVES: Patients with chronic granulomatous disease (CGD), a rare congenital disorder characterized by defective neutrophil function, frequently develop an inflammatory bowel disease similar to Crohn's disease. The clinical presentations and concordance between the features of the bowel disease in these two conditions have never been formally evaluated. METHODS: Retrospective case note analysis of all adult patients with CGD treated at a tertiary care hospital. RESULTS: A total of 25 eligible patients were identified. Of these, 14 (56%) had experienced gastrointestinal symptoms in the preceding 3 years; and 11 (44%) had documented gastrointestinal inflammation not secondary to infection, manifesting throughout the alimentary canal including the upper gastrointestinal tract (45%), small intestine (27%), colon (73%), and rectum (73%). All had discontinuous inflammation and perianal involvement, and approximately half (55%) demonstrated epithelioid granulomata on histology. All patients fulfilled the Lennard-Jones criteria for the diagnosis of Crohn's disease. Therapeutic responses were observed in five patients to 5-aminosalicylates, and in individual patients to thalidomide, interferon-gamma, azathioprine, infliximab, and intestinal resection. CONCLUSIONS: There are striking clinical and pathological resemblances between the bowel diseases observed in CGD and Crohn's disease, supporting the possibility of mechanistic similarities in their pathogenesis. Patients with CGD appear particularly prone to developing perianal disease.

GABA release by basket cells onto Purkinje cells, in rat cerebellar slices, is directly controlled by presynaptic purinergic receptors, modulating Ca2+ influx.

In many brain regions, Ca(2+) influx through presynaptic P2X receptors influences GABA release from interneurones. In patch-clamp recordings of Purkinje cells (PCs) in rat cerebellar slices, broad spectrum P2 receptor antagonists, PPADS (30microM) or suramin (12microM), result in a decreased amplitude and increased failure rate of minimal evoked GABAergic synaptic currents from basket cells. The effect is mimicked by desensitizing P2X1/3-containing receptors with alpha,beta-methylene ATP. This suggests presynaptic facilitation of GABA release via P2XR-mediated Ca(2+) influx activated by endogenously released ATP. In contrast, activation of P2Y4 receptors (using UTP, 30microM, but not P2Y1 or P2Y6 receptor ligands) results in inhibition of GABA release. Immunological studies reveal the presence of most known P2Rs in >or=20% of GABAergic terminals in the cerebellum. P2X3 receptors and P2Y4 receptors occur in approximately 60% and 50% of GABAergic synaptosomes respectively and are localized presynaptically. Previous studies report that PC output is also influenced by postsynaptic purinergic receptors located on both PCs and interneurones. The high Ca(2+) permeability of the P2X receptor and the ability of ATP to influence intracellular Ca(2+) levels via P2Y receptor-mediated intracellular pathways make ATP the ideal transmitter for the multisite bidirectional modulation of the cerebellar cortical neuronal network.
