The accuracy of dry surgical field sublabial biopsy in the diagnosis of sicca syndrome.

BACKGROUND: Sublabial gland biopsy is the 'gold standard' in establishing the diagnosis of primary Sjögren's syndrome. Bleeding and nerve damage are complications. Our centre has adopted the use of the chalazion clamp to provide a dry surgical field to address these challenges. This study aimed to assess the accuracy of minor salivary gland harvest rate using this technique. METHOD: A retrospective review of all minor salivary gland biopsies was carried out in a single tertiary referral centre over a five-year period. RESULTS: Forty-one biopsy patients were identified, with a mean age of 56.1 years. There was 100 per cent accuracy in harvest rate in our series. Twelve patients (29 per cent) were positive for primary Sjögren's syndrome. No patients had a complication immediately or at one month follow up. CONCLUSION: Dry surgical field sublabial gland biopsy is a safe and highly effective technique in the diagnosis of primary Sjögren's syndrome. Initial results indicate it may provide a higher harvest rate with fewer complications than traditional non-ischaemic techniques.

What the blogosphere has to say about adult tonsillectomy.

OBJECTIVES: Tonsillectomy has generated extensive comment on the internet, but this content has not been examined in a scientific manner. This study aimed to determine what the blogosphere has to say about adult tonsillectomy and to report whether this information can be used to improve post-surgical care. METHODS: The internet was searched to find personal blogs relating to tonsillectomy. A retrospective review of data collected on these blogs was carried out and the blogs were conceptually analysed by the authors. RESULTS: Fifty blogs were included. Seventy per cent of patients had read blogs prior to their procedure. The average pain score where available was 7.2. Complications occurred in 10 per cent of patients. Only 1 patient (2 per cent) regretted having a tonsillectomy. CONCLUSION: It is important for otolaryngologists to stay in tune with the blogosphere as this unregulated and easily accessible source of information is both friend and foe but will ultimately help in pre-operative counselling and post-operative management.

Impact and Mechanism of Covid-19 on Mental Health and Wellbeing.

The Covid-19 pandemic has brought unprecedented pressure to healthcare systems worldwide, resulting in significant and precipitous changes in demand, burden and method of delivery. The psychosocial impact of this crisis is likely to increase over the course of the pandemic, peak later than medical cases and endure for longer thereby significantly exceeding medical morbidity. It will have far reaching impact on the individual, their family and their care providers. Frontline healthcare workers and those with pre-existing mental health difficulties are recognised at increased risk. Now that the initial surge has been expertly curtailed, it is essential that urgent consideration is now directed towards the mental health implications of the current outbreak and ensure that we are as ready for the increased MH needs of the community as we were for the intensive medical care.

Irish Inquiry Reports Relating to Perinatal Deaths and Pregnancy Loss Services.

Aims External inquiries are carried out following specific adverse events in healthcare, many in maternity care; to identify issues and make recommendations to improve standards of care. Methods Ten publically-available national inquiry reports published between 2005-2018 relating to pregnancy loss services, were reviewed by 2 clinicians, separately, examining the content and recommendations from each report. Results A total of 258 recommendations were made in 9 reports (90%). Five inquiries (50%) clearly stated that affected families were involved and four (40%) involved affected clinical staff. In 9 reports (90%) recommendations included: increase workforce staffing and/or training, strengthen clinical governance, enhance adverse incident management and comprehensive data collection e.g. maternity outcomes. Only two inquiry reports (20%) stated that feedback was sought from key stakeholders prior to publication. Conclusion A collaborative and standardised inquiry process involving and supporting all persons affected as well as key stakeholders would ensure that all relevant issues are identified, recommendations are implemented and essential lessons are learned.

A large case series of temporal bone fractures at a UK major trauma centre with an evidence-based management protocol.

OBJECTIVE: To review the management of temporal bone fractures at a major trauma centre and introduce an evidence-based protocol. METHODS: A review of reports of head computed tomography performed for trauma from January 2012 to July 2018 was conducted. Recorded data fields included: mode of trauma, patient age, associated intracranial injury, mortality, temporal bone fracture pattern, symptoms and intervention. RESULTS: Of 815 temporal bone fracture cases, records for 165 patients met the inclusion criteria; detailed analysis was performed on the records of these patients. CONCLUSION: Temporal bone fractures represent high-energy trauma. Initial management focuses on stabilisation of the patient and treatment of associated intracranial injury. Acute ENT intervention is directed towards the management of facial palsy and cerebrospinal fluid leak, and often requires multidisciplinary team input. The role of nerve conduction assessment for immediate facial palsy is variable across the UK. The administration of high-dose steroids in patients with temporal bone fracture and intracranial injury is not advised. A robust evidence-based approach is introduced for the management of significant ENT complications associated with temporal bone fractures.

Effect of neoadjuvant chemoradiation on preoperative pulmonary physiology, postoperative respiratory complications and quality of life in patients with oesophageal cancer.

BACKGROUND: It remains controversial whether neoadjuvant chemoradiation (nCRT) for oesophageal cancer influences operative morbidity, in particular pulmonary, and quality of life. This study combined clinical outcome data with systematic evaluation of pulmonary physiology to determine the impact of nCRT on pulmonary physiology and clinical outcomes in locally advanced oesophageal cancer. METHODS: Consecutive patients treated between 2010 and 2016 were included. Three-dimensional conformal radiation was standard, with a lung dose-volume histogram of V20 less than 25 per cent, and total radiation between 40 and 41·4 Gy. Forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and diffusion capacity for carbon monoxide (DLCO) were assessed at baseline and 1 month after nCRT. Radiation-induced lung injury (grade 2 or greater), comprehensive complications index (CCI) and pulmonary complications were monitored prospectively. Health-related quality of life was assessed among disease-free patients in survivorship. RESULTS: Some 228 patients were studied. Comparing pulmonary physiology values before with those after nCRT, FEV1 decreased from mean(s.d.) 96·8(17·7) to 91·5(20·4) per cent (-3·6(10·6) per cent; P < 0·001), FVC from 104·9(15·6) to 98·1(19·8) per cent (-3·2(11·9) per cent; P = 0·005) and DLCO from 97·6(20·7) to 82·2(20·4) per cent (-14·8(14·0) per cent; P < 0·001). Five patients (2·2 per cent) developed radiation-induced lung injury precluding surgical resection. Smoking (P = 0·005) and increased age (P < 0·001) independently predicted percentage change in DLCO. Carboplatin and paclitaxel with 41·4 Gy resulted in a greater DLCO decline than cisplatin and 5-fluorouracil with 40 Gy (P = 0·001). On multivariable analysis, post-treatment DLCO predicted CCI (P = 0·006), respiratory failure (P = 0·020) and reduced physical function in survivorship (P = 0·047). CONCLUSION: These data indicate that modern nCRT alters pulmonary physiology, in particular diffusion capacity, which is linked to short- and longer-term clinical consequences, highlighting a potentially modifiable index of risk.

ANTECEDENTES: El tema de si en el cáncer de esófago la quimiorradioterapia neoadyuvante (neoadjuvant chemoradiation, nCRT) repercute sobre la morbilidad postoperatoria, especialmente sobre la morbilidad pulmonar y la calidad de vida de los pacientes que sobreviven sigue siendo controvertido. Este estudio combina datos sobre resultados clínicos con una evaluación sistemática de la fisiología pulmonar para determinar el impacto de la nCRT sobre la fisiología pulmonar y los resultados clínicos en el cáncer de esófago localmente avanzado. MÉTODOS: Se incluyeron pacientes consecutivos tratados entre 2010-2016. La radioterapia conformal 3D fue la estándar, con un histograma dosis-volumen del pulmón V20 < 25% y radiación entre 40-41,4 Gy. Se evaluaron el volumen espiratorio forzado (forced expiratory volume, FEV1), la capacidad vital forzada (forced vital capacity, FVC) y la capacidad de difusión del monóxido de carbono (diffusion capacity for carbon monoxide, DLCO) al inicio y un mes tras la nCRT. La lesión pulmonar inducida por la radioterapia (EORTC grado ≥ 2), el índice de complicaciones integral (comprehensive complications index, CCI), grado de Clavien-Dindo, y complicaciones pulmonares fueron analizadas de manera prospectiva. Se evaluó la calidad de vida relacionada con la salud entre los pacientes supervivientes libres de enfermedad (EORTC QLQ-C30, OG25, OES18). RESULTADOS: Se estudiaron un total de 228 pacientes. Al comparar los valores de la fisiología pulmonar antes y después de la nCRT respectivamente, la FEV1 disminuyó de 96,8 ± 17,7% a 91,5 ± 20,4% (-3,6 ± 10,6%, P = 0,0002), la FVC de 104,9 ± 15,6 a 98,1 ± 19,8% (-3,2 ± 11,9%, P = 0,005) y la DLCO de 97,6 ± 20,7 a 82,2 ± 20,4% (-14,8 ± 14,0%, P < 0,0001). Cinco pacientes (2,2%) desarrollaron lesión pulmonar relacionada con la radioterapia impidiendo la resección quirúrgica. Los factores predictores independientes de %ΔDLCO fueron el hábito tabáquico (P = 0,005) y la edad avanzada (P < 0,001). El tratamiento con carboplatino/paclitaxel/41,4Gy determinó un mayor descenso de la DLCO en comparación con cisplatino/5-fluorouracilo/40Gy (P = 0,001). En el análisis multivariable, la DLCO tras el tratamiento fue una variable predictora de CCI (P = 0,006), fracaso respiratorio/intubación prolongada (P = 0,020) y reducción de la función física en los supervivientes (P = 0,047). CONCLUSIÓN: Estos datos indican que la moderna nCRT altera la fisiología pulmonar, especialmente la difusión pulmonar, con consecuencias clínicas a corto y largo plazo. La DLCO podría constituir un factor de riesgo potencialmente modificable.

Preclinic telephone consultations: an observational cohort study.

Patients referred to secondary care for specialist respiratory review frequently undergo multiple hospital attendances for investigations and consultations. This study evaluated the potential of a preclinic telephone consultation and subsequent coordination of tests and face-to-face consultations to reduce hospital visits. Total hospital attendances were recorded for three cohorts (participants, non-participants and comparators) for 6 months from first specialist contact. Patients completed the medical interview satisfaction scale-21 (MISS-21). The study showed that a preclinic telephone consultation can significantly reduce hospital visits over a fixed period without reducing patient satisfaction. In total, 20.8% of the participant group had three or more hospital attendances compared with 42.9% of the non-participant group (p = 0.001) and 44.7% of the comparator group (p = 0.002). Participants had fewer follow up visits and lower rates of non-attendance/late rearrangement of appointments. This service reduces unnecessary hospital visits, seems to improve patient compliance and may save costs associated with non-attendance and follow up consultations.

Preclinical pharmacology of robenacoxib: a novel selective inhibitor of cyclooxygenase-2.

This manuscript reports the results of preclinical studies in the rat with robenacoxib, a novel selective cyclooxygenase (COX)-2 inhibitor. Robenacoxib selectively inhibited COX-2 in vitro as evidenced from COX-1:COX-2 IC50 ratios of 27:1 in purified enzyme preparations and >967:1 in isolated cell assays. Binding to COX-1 was rapid and readily reversible (dissociation t(1/2) << 1 min), whilst COX-2 binding was slowly reversible (t(1/2) = 25 min). In vivo, robenacoxib inhibited PGE2 production (an index of COX-2 inhibition) in lipopolysaccharide (LPS)-stimulated air pouches (ID50 0.3 mg/kg) and for at least 24 h in zymosan-induced inflammatory exudate (at 2 mg/kg). Robenacoxib was COX-1 sparing, as it inhibited serum TxB2 synthesis ex vivo (an index of COX-1 inhibition) only at very high doses (100 mg/kg but not at 2-30 mg/kg). Robenacoxib inhibited carrageenan-induced paw oedema (ID50 0.40-0.48 mg/kg), LPS-induced fever (ID50 1.1 mg/kg) and Randall-Selitto pain (10 mg/kg). Robenacoxib was highly bound to plasma protein (99.9% at 50 ng/mL in vitro). After intravenous dosing, clearance was 2.4 mL/min/kg and volume of distribution at steady-state was 306 mL/kg. Robenacoxib was preferentially distributed into inflammatory exudate; the AUC for exudate was 2.9 times higher than for blood and the MRT in exudate (15.9 h) was three times longer than in blood (5.3 h). Robenacoxib produced significantly less gastric ulceration and intestinal permeability as compared with the reference nonsteroidal anti-inflammatory drug (NSAID), diclofenac, and did not inhibit PGE2 or 6-keto PGF(1alpha) concentrations in the stomach and ileum at 30 mg/kg. Robenacoxib also had no relevant effects on kidney function at 30 mg/kg. In summary, results of preclinical studies in rats studies suggest that robenacoxib has an attractive pharmacological profile for potential use in the intended target species, cats and dogs.

Cardiac troponin I and N-terminal pro-brain natriuretic peptide in umbilical artery blood in relation to fetal heart rate abnormalities during labor.

The use of continuous fetal heart rate (FHR) recordings to monitor fetal well-being during labor is standard clinical practice in developed countries. Little is known about the relationship, if any, that exists between these FHR abnormalities and the fetal cardiac musculature and function. The aim of this study was to investigate umbilical artery serum levels of cardiac troponin I, a sensitive and specific marker of myocardial necrosis, and N-terminal pro-brain natriuretic peptide (pro-BNP), a sensitive marker of left ventricular dysfunction, in relation to FHR abnormalities. Umbilical artery blood samples were taken from 27 cases immediately after delivery of the infant. There was evidence of significant FHR abnormalities in 11 of these cases (group 2) and the FHR recording was normal in 16 cases (group 1). The mean N-terminal pro-BNP level in umbilical artery serum in group 2 was 413 fmol/L (SEM = 85) and in group 1 was 223 fmol/L (SEM = 28)(p = 0.022). There was no significant difference observed in cardiac troponin I levels between the two groups. Umbilical artery serum N-terminal pro-BNP is elevated in association with fetal heart rate abnormality in the late stage of labor. This finding suggests that some degree of cardiac compromise accompanies FHR abnormality.

Amino-terminal pro-brain natriuretic peptide in normal and hypertensive pregnancy.

OBJECTIVES: To investigate serum levels of amino-terminal pro-brain natriuretic peptide (Nt pro-BNP) as an index of left-ventricular function in normal pregnancy and pregnancies complicated by hypertension and also to investigate levels in both primigravid and multigravid women. METHODS: Women with hypertension in pregnancy (at least two readings of systolic blood pressure > 140 mm Hg and diastolic blood pressure > 90 mm Hg) (n = 24) and normotensive women (n = 42) were included in the study. Serum Nt pro-BNP was measured using an enzyme-linked immunosorbent assay technique. RESULTS: The median serum Nt pro-BNP level in pregnancies complicated by hypertension was 420 fmol/L, which was significantly greater than that measured in samples obtained from normotensive women in pregnancy (340 fmol/L) (p = 0.03). There was a nonsignificant trend toward increased levels in proteinuric as compared to nonproteinuric hypertension in pregnancy. Multigravida had higher Nt pro-BNP levels (n = 26; median Nt pro-BNP = 358 fmol/L) than primigravida (n = 16; median Nt pro-BNP = 278 fmol/L) (p = 0.01) in association with normal pregnancy. Multigravida also demonstrated a dramatic rise in serum Nt pro-BNP levels in association with hypertension in pregnancy (n = 13; median Nt pro-BNP = 572 fmol/L) as compared to normal pregnancy (n = 26; median Nt pro-BNP = 358 fmol/L) (p = 0.009). CONCLUSION: Serum Nt pro-BNP is elevated in women with hypertensive disorders of pregnancy, indicating elevated left-ventricular filling pressures. Measured serum levels in both normal and hypertensive pregnancy are higher in multigravida than in primigravida.

Learning disability nursing: shared learning should be encouraged.

People with learning disabilities often have multiple and complex health needs and need access to a range of specialist skills. Professionals are often unclear about each other's roles. Sharing common areas of learning will lead to a greater understanding of these roles.
