'After they see what you have, they contact you': a qualitative study of national team football players', coaches' and clinicians' experiences in engaging with a context-specific injury surveillance system.

BACKGROUND: Sports injury surveillance systems aid injury prevention, but their development without considering end-users' perspectives has led to low adherence and honesty in self-reporting by players, compromising their effectiveness. Context-specific injury surveillance systems have been proposed to address these challenges, but there is a limited understanding of stakeholders' perceptions and experiences in using them. OBJECTIVE: Following the implementation of a context-specific injury surveillance system with 100% player adherence over 60 weeks, the study aimed to investigate Under-21 Maltese national football team players', coaches' and clinicians' experiences of how and why they engaged with the system. METHOD: Seventeen semi-structured interviews with Under-21 Maltese male national football team players (n = 12), their coaches (n = 3) and clinicians (n = 2) were conducted. Data were analysed using reflexive thematic analysis. RESULTS: Participants highlighted questionnaire-related factors that motivated engagement with the context-specific injury surveillance system (theme 1) and factors influencing further engagement with the system based on stakeholders' actions (theme 2). Perceived outcomes experienced as a result of engaging with the injury surveillance system (theme 3), in turn, motivated players to continue reporting and engaging with the system. CONCLUSION: To encourage players' sustained reporting, injury-related information collected from well-designed questionnaires should serve to stimulate communication and teamwork among stakeholders, to prevent injuries and enhance performance.

Encephalitis as an initial presentation of type 2 amiodarone-induced thyrotoxicosis.

We report a case of a woman in her mid-20s presenting with encephalitis as the initial presentation of type 2 amiodarone-induced thyrotoxicosis (AIT). She was on amiodarone in view of a history of hypertrophic cardiomyopathy. Symptomatology included acute personality change and focal myoclonic jerks.Cerebrospinal fluid analysis showed a non-specific protein count elevation with negative microbiology, virology, autoimmune screen and onconeural antibodies. The electroencephalogram was consistent with a generalised cerebral dysrhythmia. An MRI of the head revealed symmetrical oedema within the motor cortices and a high T2 signal within the cerebellar dentate nuclei, with no restricted diffusion. Blood investigations confirmed thyrotoxicosis with negative antithyroid antibodies. She did not fulfil the criteria for a thyroid storm. Other possible causes of encephalitis were excluded.There was an excellent clinical, laboratory and radiological response to glucocorticoids, suggesting a diagnosis of steroid-responsive encephalitis secondary to type 2-AIT in the absence of a thyroid storm.

Thyroid dysfunction in pregnancy - a retrospective observational analysis of a Maltese cohort.

BACKGROUND: Thyroid dysfunction is known to adversely affect pregnancy. This study evaluates the prevalence of thyroid disorders and explores their association with pregnancy complications/comorbidities and modes of delivery in the Maltese pregnant population over a ten year period. DESIGN: A population based observational study. METHOD: We analysed data from the National Obstetrics Information Service of the Department of Health Informations and Research (NOIS) for all births delivered in Malta between 2006 and 2016. Cases identified and recorded by NOIS to have had some form of thyroid dysfunction during pregnancy were confirmed by cross-referencing  with laboratory results found in patients' medical records and/or iSOFT® database system. Using the Statistical Package for the Social sciences (SPSS®)  demographic data, past obstetric and medical history and obstetric outcomes were analysed for pregnancies with thyroid dysfunction and compared to data pertaining to pregnancies in euthyroid patients, that is those with no recorded thyroid dysfunction on NOIS. Chi square/Fisher's exact test were used to compare categorical variables while ANOVA/Mann-Whitney U test was used to compare continuous variables. Statistical significance was defined by a two-sided p value <0.05. RESULTS: Data was available for 46,283 women (mean [SD] age = 29.2 [5.4] years). 587 pregnancies (1.3%) suffered from thyroid dysfunction. Of these, 67.3% were hypothyroid, 3.2% had hyperthyroidism, 28.3% had isolated hypothyroxinaemia (IHT) while 1.2% had a history of thyroid carcinoma. Patients with IHT and hypothyroidism were older than euthyroid patients (p < 0.001).  IHT and hypothyroid patients had a statistically significant higher body mass index (BMI) than euthyroid women (p=0.001 for hypothyroid women, p = 0.035 for IHT). Hypothyroid  and IHT women were more likely to have had a previous lower segment caesarean section  (p=0.043,  and 0.006 respectively). Type 1 diabetes and gestational diabetes  p = 0.012) were more common associated comorbidities in hypothyroid pregnancies. Offspring of patients with IHT had a higher birth weight than those born to euthyroid patients (p=0.009). Patients with hyperthyroidism were found to have a significantly increased risk of early preterm delivery before 34 weeks of gestation and were also more likely to have suspected intrauterine growth restriction and low mean birth weight. We report no significant differences in past history of obstetric loss, antenatal complications, mode of delivery, gestational age at delivery and postpartum haemorrhage rates across thyroid categories. CONCLUSIONS: Available evidence suggests that thyroid dysfunction is more likely in the setting of older age, and higher body mass index. Moreover, it impacts on neonatal birth weight, rates of early preterm delivery and intrauterine growth restriction.

Perceiving, reporting and managing an injury - perspectives from national team football players, coaches, and health professionals.

BACKGROUND: Injury perceptions and related risk-mitigating interventions are context-dependent. Despite this, most injury surveillance systems are not context-specific as they do not integrate end-users perspectives. PURPOSE: To explore how Maltese national team football players, coaches, and health professionals perceive a football-related injury and how their context influences their perceptions and behaviours towards reporting and managing a football injury. METHODS: 13 semi-structured interviews with Maltese female and male national team football players (n = 7), coaches (n = 3), and health professionals (n = 3) were conducted. Data were analysed using thematic analysis. RESULTS: Three themes were identified: (1) How do I perceive an injury? Consisted of various constructs of a sports injury, yet commonly defined based on performance limitations. (2) How do I deal with an injury? Encapsulated the process of managing the injury (3) What influences my perception, reporting and management of an injury? Comprised personal and contextual factors that influenced the perception and, consequently, the management of an injury. CONCLUSION: Performance limitations should be used as part of future injury definitions in injury surveillance systems. Human interaction should be involved in all the processes of an injury surveillance framework, emphasising its active role to guide the injury management process.

Predictors of autoimmune thyroid disease.

This case-control study sought to investigate whether thyroid autoimmunity is significantly associated with identifiable and potentially modifiable environmental factors. A total of 324 individuals were recruited: 164 cases (with positive thyroid peroxidase antibodies [TPO-Ab] and/or thyroid-stimulating hormone receptor antibodies [TSH-R Ab]) and 160 controls (negative antibodies) who had been screened for thyroid autoimmunity within the previous 12 months. A questionnaire sought information on drug, social, and reproductive history, stress, and iodine intake, while blood specimens were collected to measure glycosylated hemoglobin, thyroid function, TPO-Ab/TSH-R Ab status, 25-hydroxyvitamin D level, and hepatitis C antibody status. Both TPO-Ab-positive and TSH-R Ab-positive individuals were exposed to a higher amount of smoking pack-years (P = 0.038 and 0.037, respectively). No significant predictors of TSH-R Ab positivity were identified on multivariate regression analysis. The odds for TPO-Ab positivity was increased by female gender (odds ratio [OR] 2.815, 95% confidence interval [CI], 1.387, 5.714; P = 0.004) and discontinuation of smoking (OR 2.367, 95% CI, 1.213, 4.621; P = 0.012), while birth in winter (OR 0.470, 95% CI, 0.253, 0.871; P = 0.017) and higher intake of iodine-rich foods (OR 0.864, 95% CI, 0.761, 0.981; P = 0.024) decreased the odds for TPO-Ab development. Therefore, avoidance of ever starting smoking and correction of iodine deficiency may help protect against TPO-Ab development.

Retiform Purpura of the Lower Limbs Associated with Levamisole-Adulterated Cocaine.

A young man was treated in hospital for sepsis, disseminated intravascular coagulation and multi-organ failure. He was a regular intranasal cocaine user up to 1 day prior to symptom onset. Clinical examination revealed extensive retiform purpura affecting both his lower limbs. Skin biopsy revealed widespread thrombosis in the small- and medium-sized vessels of the mid dermis and the subcutaneous fat with surrounding leucocytoclasis. There was also extensive ischaemic necrosis of the upper reticular and papillary dermis and focal ischaemic necrosis of the epidermis. These findings were in keeping with a thrombotic vasculopathy with associated cutaneous ischaemic necrosis, likely associated with levamisole-adulterated cocaine (LAC). An autoimmune screen showed extremely raised levels of anti-B2-glycoprotein IgM, IgG and anti-cardiolipin IgG antibodies, usually seen in antiphospholipid syndrome (APS). The literature describes how APS could be secondary to various underlying conditions, including LAC, and that levamisole toxicity may mimic APS and hence be missed. LEARNING POINTS: Levamisole is a common adulterant found in cocaine; the resultant toxicity can present with cutaneous manifestations, namely retiform purpura and skin necrosis, similar to antiphospholipid syndrome.Patients presenting with such features should be asked about illicit drug use, specifically cocaine, and investigated by screening urine for drugs of abuse and serum antihuman elastase antibody when possible.

Neurosyphilis in a suspected case of giant cell arteritis.

A 67-year-old man had a few month history of deteriorating visual acuity. He had originally presented to ophthalmology with right-sided visual blurring. This subsequently progressed to involve the left eye. At this point, he was empirically treated with high-dose glucocorticoids, both orally and intravenously, with the suspicion that giant cell arteritis was causing acute visual deterioration of his left eye. Unfortunately, his symptoms did not improve. During an admission to hospital for a pneumonia, he underwent further investigations for this bilateral visual loss. He was diagnosed with left neuroretinitis and right vitritis. A thorough workup revealed positive syphilis serology and cerebrospinal fluid was positive on venereal disease research laboratory testing. He was diagnosed and treated for neurosyphilis with intravenous benzylpenicillin 4 million units 4 hourly for 14 days. His left-sided vision improved but he still suffers from severe visual impairment in his right eye.

Post-Streptococcus mitis infection polyserositis.

We report a case of a 42-year-old man who presented with acute epigastric and retrosternal chest pain and exertional dyspnoea, and was subsequently diagnosed with polyserositis secondary to post-Streptococcal mitis infection. A CT scan showed a large pericardial effusion requiring pericardiocentesis, small bilateral pleural effusions and small amount of ascites. Several serological tests were done, which were all found to be normal. Pericardial and pleural fluid aspirates revealed an exudate. Culture of the pleural fluid yielded growth of S.  mitis and this was deemed the cause of the polyserositis, which is rare. The patient made a spontaneous recovery. He was started on colchicine by the cardiologists to help prevent pericardial fluid recurrence and this was continued for 3 months. A dental review confirmed the presence of dental caries, the possible source of infection. On follow-up, the patient remained well with no further relapses.

Adrenal medullary hyperplasia mimicking pheochromocytoma.

A 59-year-old woman, a known case of hypertension, was incidentally diagnosed with a large right-sided adrenal mass. Investigations for a functional adrenal lesion resulted in very high preoperative norepinephrine levels. A right adrenalectomy was performed. Histology showed adrenal medullary hyperplasia (AMH). AMH is a rare diagnosis and its incidence is poorly documented in the literature. This is a benign entity which resembles pheochromocytoma (PCC) in both clinical and biochemical manner. AMH is usually bilateral and may occur in isolation or in association with PCC. In fact, some authors consider it to be a precursor to PCC. Thus, these patients need long-term follow-up in view of the risk of development of PCC later.

Pre-eclampsia complicated by severe hyponatraemia.

A 41-year-old woman was diagnosed with pre-eclampsia at 35 weeks gestation. She was treated with antihypertensives but, unfortunately, her condition became complicated by severe hyponatraemia. Her sodium levels rapidly dropped to 125 mmol/L. The cause for the hyponatraemia was the syndrome of inappropriate antidiuretic hormone secretion. She was initially managed with fluid restriction, but an emergency caesarean section was necessary in view of fetal distress. Her sodium levels returned to normal within 48 hours of delivery.Pre-eclampsia is rarely associated with hyponatraemia. A low maternal sodium level further increases the mother's risk for seizures during this state. Additionally, the fetal sodium rapidly equilibrates to the mother's and may result in fetal tachycardia, jaundice and polyhdraminios. All these factors may necessitate an emergency fetal delivery.

Association of cholesterol and lifestyle markers with type 1 diabetes incidence rates at a population level.

Background: We investigated the hypotheses that mean population body mass index (BMI), systolic blood pressure (SBP), fasting plasma glucose (FPG), total cholesterol (TC) and the prevalence of type 2 diabetes (T2DM) are correlated with type 1 diabetes (T1DM) incidence rates. Methods: Population-based mean incidence rates for T1DM in children aged ≤14 years participating in the World Health Organization Diabetes Mondial (DiaMond) project were compared with population mean values for BMI, SBP, TC and FPG, as well as prevalence rates for T2DM as reported by The Global Burden of Metabolic Risk Factors Chronic Diseases Collaborating Group, using Spearman's rank correlation and multiple regression analysis. Results: The mean incidence rate for T1DM in boys was significantly correlated with country mean BMI, SBP and TC in men and mean TC in women, and negatively correlated with the country incidence of T2DM in either gender. We also found significant correlations between mean incidence rates of T1DM in girls and mean BMI, SBP and TC in men and mean TC in women. In multiple regression analyses, mean TC emerged as the sole significant predictor for T1DM in both boys (P < 0.001, adjusted R2 = 0.393) and girls (P < 0.001, adjusted R2 = 0.372). Conclusion: Population mean total cholesterol is a significant predictor for country incidence of type 1 diabetes in both boys and girls. This association may fuel the rising incidence rates of type 1 diabetes reported in many countries.

Carbimazole-induced exudative pleural effusions.

Carbimazole, an antithyroid drug, is associated with a significant number of side effects, but pleuropulmonary complications are rare. We report the case of a 42-year-old Caucasian man who developed dyspnoea secondary to bilateral exudative pleural effusions while on carbimazole therapy. Extensive investigations, including a vasculitic screen, ruled out other potential causes for this patient's clinical presentation. This patient's pleural effusions gradually resolved within a few months of stopping carbimazole therapy, suggesting a role for the latter in the aetiopathogenesis of his presentation. Clinicians should consider discontinuing treatment with carbimazole and introducing alternative antithyroid therapy in this setting, once other potential causes of a pleural effusion have been systematically ruled out.

Refractory hypocalcaemia complicating metastatic prostatic carcinoma.

A 72-year-old man with a background of ischaemic heart disease was referred to the accident and emergency department with a 1-week history of worsening dyspnoea and lethargy. A chest X-ray revealed a right-sided lobar pneumonia and a prolonged corrected QT interval was noted on his ECG at presentation. Laboratory investigations confirmed severe hypocalcaemia, significant vitamin D deficiency and relative hypoparathyroidism. A markedly elevated prostate-specific antigen was also identified. Bone scintigraphy demonstrated widespread osteoblastic bone metastases. Severe hypocalcaemia persisted despite treatment and he succumbed after 60 days of hospitalisation.
