The role of single pill combination therapy for stroke prevention remains to be established. We explored the perspectives of stroke survivors and healthcare professionals on single pill combination therapy for stroke prevention.

We conducted focus groups involving stroke survivors and healthcare professionals.

We recruited six stroke survivors: four (67%) were female and mean age was 70 ± 12 years; and eight healthcare professionals (three Stroke Consultants, two Nurse Specialists, three General Practitioners). Improved adherence is the main perceived benefit of single pill combination therapy, although concerns exist surrounding less individualised care, unsuitability for use in the acute setting, reduced ability to titrate doses and difficulty identifying the cause of side effects. The clinical stability of patients, alongside single pill combination therapy efficacy, cost, side effect profile and evidence base for impact on risk factors and clinical outcomes are key factors influencing acceptability. Stroke survivors and healthcare professionals feel single pill combination therapy is most suitable for stable patients, although there is no evidence base for its use in this context.

Stroke healthcare professionals and stroke survivors are most amenable to using single pill combination therapy for stable patients, although its role in this context should be evaluated in studies with risk factor targets and clinical outcomes as endpoints.

Capillary (finger prick) blood sampling is commonplace in paediatric practice but this method is prone to produce spurious laboratory results.

A five-year-old girl presented with abdominal pain, epigastric tenderness, tachycardia and reduced oxygen saturation. A venous blood sample haemolysed, and serum amylase on a finger prick sample was reported as 2831 units/L. The working diagnosis was acute pancreatitis and respiratory tract infection. A repeat amylase 9 h later was within the normal range. The patient was known to bite her fingers and the possibility of salivary contamination was considered. Serum isoenzyme analysis confirmed presence of high salivary amylase levels with no pancreatic amylase detected. A viral respiratory tract infection and buried gastrostomy bumper were eventually thought to account for the patient’s presentation.

Increased awareness of the potential for salivary contamination of serum amylase in finger prick samples may prevent misdiagnoses of pancreatitis.

von Willebrand disease is the most common hereditary coagulopathy and is characterised by a deficiency in the quantity or quality of the von Willebrand factor. Heyde Syndrome, in contrast, is an acquired form of von Willebrand syndrome (AVWS) due to calcific aortic valve stenosis, characterised by gastrointestinal bleeding from angiodysplasia.

A 73-year-old patient presented with severe gastrointestinal bleeding and stated that she suffered from hereditary von Willebrand disease. Upon echocardiography, a severe aortic valve stenosis was found, and hence the suspicion of additional AVWS was raised. Since endoscopic interventions and conservative therapeutic approaches did not result in a cessation of the bleeding, transcatheter aortic valve implantation (TAVI) was performed to stop the additional shear stress on von Willebrand factor. This resulted in cessation of the bleeding.

Retrospectively, this life-threatening gastrointestinal bleeding was a result of severe Heyde Syndrome, which could be alleviated by TAVI. Whether the patient had suffered from inherited von Willebrand disease in the past, remains uncertain. AVWS should be considered in patients with suspected inherited von Willebrand disease and concomitant severe aortic valve stenosis, since it constitutes a treatable cause of a potentially severe bleeding disorder.

Sialorrhoea, which has been defined as excessive amount of saliva in the mouth, can be a debilitating symptom. Psychoactive drugs may cause an increase or decrease in saliva secretion. Antidepressant drugs, especially tricyclic antidepressants and less often serotonin reuptake inhibitors, are often associated with a decrease in salivation and the complaint of dry mouth.

A 46-year-old male patient with complaints of being depressed, lack of motivation, irritability and difficulty in falling asleep was started on sertraline treatment and had trouble with sialorrhoea after the dose increase, without other causes of hypersalivation.

We could not find report of any case with antidepressant-associated sialorrhoea in the literature. Future cases may support a relationship between sertraline and sialorrhoea.
