Visual loss in pregnancy.

Visual loss in pregnancy may be caused by a variety of reasons including pituitary adenomas. Prolactinomas (PRLs) are the most common hormone-secreting tumours in pregnant women. As most PRLs present with menstrual abnormalities, infertility or galactorrhoea, they are most commonly diagnosed before pregnancy. We present the case of a 30-year-old primigravida who presented at 36+5 weeks gestation with headaches and left-sided visual loss. MRI of the pituitary gland confirmed a 10×11 mm left suprasellar mass. Results of her anterior pituitary function were unremarkable for her gestational age. Postpartum, she underwent an endoscopic endonasal resection of the pituitary tumour. The histology was consistent with a PRL. Literature review reveals only one possible case of a new diagnosis of a PRL during pregnancy. It highlights the importance to consider a wide range of differential diagnoses when assessing visual loss in pregnancy.

Man with epigastric pain and persistently elevated serum lipase.

Serum lipase and amylase are commonly requested in individuals presenting with abdominal pain for investigation of acute pancreatitis. Pancreatic hyperenzymaemia is not specific for acute pancreatitis, occurring in many other pancreatic and non-pancreatic conditions. Where persistent elevation of serum lipase and amylase occurs in the absence of a diagnosed cause or evidence of laboratory assay interference, ongoing radiological assessment for pancreatic disease is required for 24 months before a diagnosis of benign pancreatic hyperenzymaemia can be made. We report a case of a 71-year-old man with epigastric pain and elevated serum lipase levels. He was extensively investigated, but no pancreatic disease was detected. He is asymptomatic, but serum lipase levels remain elevated 18 months after his initial presentation.

Rare case of meningococcal sepsis-induced testicular failure, primary hypothyroidism and hypoadrenalism: Is there a link?

Severe illness can lead to multiple transient endocrinopathies. In adult patients, neuroendocrine alterations include sick euthyroid syndrome, an increase in corticosteroid levels, increase in prolactin levels, decreased insulin growth factor 1 levels and hypogonadism. We report the case of a 24-year-old man with meningococcal sepsis with multiple end-organ complications who developed persistent non-autoimmune hypothyroidism, adrenal insufficiency and primary hypogonadism all requiring hormone replacement. While adrenal insufficiency as part of the Waterhouse-Friderichsen syndrome is well described, reports of primary hypothyroidism and persistent primary hypogonadism in severe illness are exceedingly rare. Multiple combined endocrinopathies as in this case have not been reported previously. This case highlights the necessity of screening for endocrine abnormalities in severe illness and the need for treatment if persistent. It also raises a novel concept of meningococcal sepsis causing multiple endocrinopathies possibly via disseminated intravascular coagulopathy-related ischaemic damage.
