Primary cutaneous lymphomas: exploration of 10-year data from supraregional mutlidisciplinary team meetings in Glasgow, UK.

Primary cutaneous lymphomas (PCLs) are non-Hodgkin lymphomas, presenting in the skin. They are classified into cutaneous B-cell lymphomas (CBCLs) or cutaneous T-cell lymphomas (CTCLs). The most common CTCL subtypes are mycosis fungoides (MF) and Sézary syndrome (SS). All patient's cases should be discussed at a specialist multidisciplinary team (MDT) meeting. This is the first published review, to our knowledge, of PCL MDT case discussion in the UK. Patient cases between 2008 and 2019 were reviewed to assess: frequency of PCL subtype, documentation of CTCL staging and management of MF/SS. Of 356, 103 (29%) were CBCLs and the majority (n = 200, 56%) were CTCLs. MF/SS was the diagnosis in 120 (34%). Staging was documented in 44% (n = 53) of patients with MF/SS. Management largely followed guidelines for MF/SS, topical corticosteroids were the most common treatment (n = 93, 78%). Frequency of PCL subtype is largely comparable with previously published data. Documentation of CTCL staging is low, but higher than other reports. Our work begins to address the gap in real-world data on CTCLs. A standardized approach to data collection would inform clinical practice.

Paediatric dermatology teleconsultations: a survey of healthcare professionals in the UK.

The COVID-19 pandemic catapulted dermatology services into a digital era, with the rapid introduction of teleconsultations. The UK National Health Service operational planning guidance recommends ≥ 25% of consultations are delivered remotely. There is a lack of data regarding the acceptability and effectiveness of paediatric dermatology teleconsultations. We surveyed UK healthcare professionals (HCPs) to explore their experiences of teleconsultations in paediatric dermatology, with a focus on follow-up consultations for paediatric eczema (PE), to inform a future clinical trial. There were 119 responses. Pre-pandemic, 37% provided some form of teleconsultation service, rising to 92% post-pandemic. In total, 41% (n = 49) now carry out > 25% of consultations remotely. We found 55% felt teleconsultations were less effective than face-to-face ones for PE follow-up. Eighty HCPs offered teleconsultations for PE. Among the HPCs who offered teleconsultations for PE, the most effective format for follow-up consultations was felt to be telephone with photographs (52/80, 65%). Our results demonstrate varying opinion on the effectiveness and optimal format of paediatric teleconsultations, supporting the need for further research.

Curious facial plaque diagnosed as nodular primary localised cutaneous amyloidosis.

Nodular primary localised cutaneous amyloidosis (NPLCA) is the rarest form of cutaneous amyloidosis, with a predilection for facial and acral skin. We present a 63-year-old Caucasian with a 10-year history of an asymptomatic plaque on his left cheek, starting 2 years after being scratched by a cat in the same area. A biopsy showed nodules of eosinophilic material in the deep dermis and subcutaneous fat, with plasma cells in the dermis. Congo red staining displayed apple-green birefringence within the eosinophilic material. Immunohistochemistry for serum amyloid P was positive within the eosinophilic material and immunohistochemistry showed lambda light chain restriction within the plasma cells, consistent with NPLCA. The causal relationship of the cat scratch to NPLCA in our patient remains unclear. While trauma-induced amyloidosis has been recognised in papular and macular amyloid, few case reports indicate an association with nodular amyloidosis.

Managing children with sialorrhoea (drooling): Experience from the first 301 children in our saliva control clinic.

OBJECTIVES: Sialorrhoea (drooling) is defined as the involuntary escape of saliva from the mouth. It is considered normal in young children but may cause social problems in older children. Sialorrhoea is frequently seen in children with cerebral palsy, with rates between 10% and 58% and in other neurodevelopmental diseases. Management of these children can be challenging and often requires an individual and stepwise approach. This is a large case series of children managed at the saliva control clinic in Glasgow, Scotland. METHODS: A chart review of all children attending the saliva control clinic between 2006 and June 2012 was performed. This was to ensure that all children would have long term follow up (3 years minimum). Drooling severity was assessed on the child's first attendance at clinic, and at review following a treatment option, using the Teacher Drooling Scale (TDS). RESULTS: The total number of children attending this clinic was 301, of which 274 had adequate records for inclusion in the study. 176 (64%) were male. The mean age was 7.3 (median 5) years. In terms of development 35 (13%) of children were developing normally and 50 (18%) had general developmental delay. There were 105 (38%) children with cerebral palsy. The final management of sialorrhoea in these children was simple reassurance and advice for 34 (12%), speech and language therapy for 62 (23%) anticholinergics in 90 patients (33%), botox for 30 (11%) and surgery for 71 (26%) children. The rate of non-tolerance of anticholinergics is 30%; 90 of the 298 children tried on anticholinergics had side effects leading to the treatment being stopped. The average teachers drooling score was 4.24 before clinic and 1.59 after clinic. Satisfactory results were achieved in 215 (78%) of children. CONCLUSION: Our data illustrates that effective patient management requires all treatment options to be available, including speech therapy, medications, botulinum toxin and surgery. This is one of the larger case series of children attending a saliva control clinic.

Botulinum toxin A for children with salivary control problems.

OBJECTIVE: The aim of this study was to review the response of children who have received botulinum toxin A (BtA) injections for saliva control in our institution. METHODS: Retrospective case series of children attending a saliva control clinic in a paediatric tertiary referral hospital. Children were identified from the saliva control database, which has been in place since its creation in 2006. Prior to receiving BtA all the children in the study had previously undertaken a 3-month trial of pharmacological therapy, with no effect. All BtA injections were performed freehand to the parotid and submandibular glands. The background diagnosis, comorbidities for the child, age at presentation, dose of BtA, the response, and any complications were recorded. RESULTS: 97 children were identified and 175 BtA doses were given (median per child: 1, mean: 1.9). 59 (61%) were male. The age range was between 2 months and 18 years (mean 8.6 years, median 8.8 years). The dose injected varied between 0.52 units/kg and 21.28 unit/kg (mean 5 units/kg, median 4.2 units/kg). These were performed using local anaesthetic on 131 (75%) occasions. The remainder were performed under general anaesthetic. Responses to BtA were classed as effective 109 (62%), partially effective 14 (8%) or not effective 50 (29%). The response duration was between 0.25 and 18 months (mean 4 months). Complications were seen following 22 injections (10.9%). Data modelled using binary logistic regression found that male gender and children with cerebral palsy are statistically predicted to have a better response to BtA. CONCLUSION: Botulinum A injected under local anaesthetic is a safe, effective treatment for children with sialorrhoea. Ultrasound guidance is not necessary as long as anatomical landmarks are used for placement. The main adverse effect that can result is dysphagia, which is of concern in children that can swallow independently prior to injection. Male sex and cerebral palsy are statistically independent positive predictive factors for successful outcome of BtA injections for sialorrhoea, however this does not preclude other children from receiving or benefitting from it. Children that respond well to BtA initially, are likely to respond well in the future.

Amino acid content of selected plant, algae and insect species: a search for alternative protein sources for use in pet foods.

In response to global economic duress and heightened consumer awareness of nutrition and health, sustainable and natural ingredients are in demand. Identification of alternative sources of nitrogen and amino acids, including taurine, may help meet dietary requirements while fostering sustainability and natural feeding approaches. Twenty plants, eighteen marine algae and five insect species were analysed. All samples were freeze-dried, hydrolysed and filtered prior to amino acid analysis. Samples for amino acids were analysed in duplicate and averaged. Nitrogen was analysed and crude protein (CP) determined by calculation. With the exception of taurine concentration in soldier fly larvae, all insects exceeded both the National Research Council's canine and feline minimal requirements (MR) for growth of all essential amino acids (EAA) and CP. Although some plants and marine algal species exceeded the canine and feline MR for growth for EAA and CP, only very low concentrations of taurine were found in plants. Taurine concentration in insects was variable but high, with the greatest concentration found in ants (6·42 mg/g DM) and adult flesh flies (3·33 mg/g DM). Taurine was also high in some macroalgae, especially the red algal species: Mazaella spp. (4·11 mg/g DM), Porphyra spp. (1·22 mg/g DM) and Chondracanthus spp. (6·28 mg/g DM). Preliminary results suggest that insects and some marine algal species may be practical alternatives to traditional protein and supplemental taurine sources in pet foods. Safety, bioavailability, palatability and source variability of alternative items as food ingredients should be investigated prior to incorporation into canine and feline diets.

Gaps in detailed knowledge of human papillomavirus (HPV) and the HPV vaccine among medical students in Scotland.

BACKGROUND: A vaccination programme targeted against human papillomavirus (HPV) types 16 and 18 was introduced in the UK in 2008, with the aim of decreasing incidence of cervical disease. Vaccine roll out to 12-13 year old girls with a catch-up programme for girls aged up to 17 years and 364 days was accompanied by a very comprehensive public health information (PHI) campaign which described the role of HPV in the development of cervical cancer. METHODS: A brief questionnaire, designed to assess acquisition of knowledge of HPV infection and its association to cervical cancer, was administered to two different cohorts of male and female 1st year medical students (school leavers: 83% in age range 17-20) at a UK university. The study was timed so that the first survey in 2008 immediately followed a summer's intensive PHI campaign and very shortly after vaccine roll-out (150 students). The second survey was exactly one year later over which time there was a sustained PHI campaign (213 students). RESULTS: We addressed three research questions: knowledge about three specific details of HPV infection that could be acquired from PHI, whether length of the PHI campaign and/or vaccination of females had any bearing on HPV knowledge, and knowledge differences between men and women regarding HPV. No female student in the 2008 cohort had completed the three-dose vaccine schedule compared to 58.4% of female students in 2009. Overall, participants' knowledge regarding the sexually transmitted nature of HPV and its association with cervical cancer was high in both year groups. However, in both years, less than 50% of students correctly identified that HPV causes over 90% of cases of cervical cancer. Males gave fewer correct answers for these two details in 2009. In 2008 only around 50% of students recognised that the current vaccine protects against a limited subset of cervical cancer-causing HPV sub-types, although there was a significant increase in correct response among female students in the 2009 cohort compared to the 2008 cohort. CONCLUSIONS: This study highlights a lack of understanding regarding the extent of protection against cervical cancer conferred by the HPV vaccine, even among an educated population in the UK who could have a vested interest in acquiring such knowledge. The intensive PHI campaign accompanying the first year of HPV vaccination seemed to have little effect on knowledge over time. This is one of the first studies to assess detailed knowledge of HPV in both males and females. There is scope for continued improvements to PHI regarding the link between HPV infection and cervical cancer.

Effects of genetic management on reproduction, growth, and survival in captive endangered pygmy rabbits (Brachylagus idahoensis).

A quarter of all lagomorph species worldwide are threatened with extinction. Captive breeding programs, such as that developed for the Columbia Basin (CB) pygmy rabbit (Brachylagus idahoensis), sometimes are implemented as emergency conservation measures to restore small, genetically distinct populations. However, small source populations also may have low genetic diversity, which may influence attributes related to fitness, including growth, survival, and reproduction. We used mixed-effects regression models to explore the influence of genetic pedigree (% CB) on pairing success, growth, and survival during the 10-year captive breeding program at Washington State University, which included controlled pairings and outbreeding with pygmy rabbits from Idaho. Pairing success, juvenile growth, and juvenile survival declined with increasing CB pedigree of 1 or both parents, suggesting inbreeding depression among the small number of related founders. Demographic variables such as age, sex, and previous pregnancies, and environmental variables such as month and temperature at birth also were associated with production of pygmy rabbits. Our study illustrates the difficulty of retaining a unique genome of a small source population while simultaneously producing enough rabbits for restoration into natural habitat as part of endangered species recovery programs.
