Intravenous methylprednisolone-induced hypokalaemic periodic paralysis in a thyrotoxic patient: a case report and literature review.

Hypokalaemic periodic paralysis (HPP) is an uncommon complication of corticosteroid therapy, which may also be seen in thyrotoxicosis. It was mostly described in the Asian population, and it is rare in other ethnic groups. We present the case of a poorly controlled thyrotoxic Caucasian male with thyroid eye disease (TED) who suffered an acute quadriplegic episode caused by severe hypokalaemia and was admitted to the intensive care unit (ITU) within 24 hours of initiating intravenous methylprednisolone (IVMP) infusion.

Serosurveillance of SARS-CoV-2 in companion animals in Sarawak, Malaysia.

SARS-CoV-2 is a zoonotic betacoronavirus that was first reported at the dawn of 2019 in Wuhan, China and has since spread globally, causing an ongoing pandemic. Anthroponotic transmission was reported early, with confirmed infections reported in 26 species to date, including dogs and cats. However, there is a paucity of reports on the transmission of SARS-CoV-2 to companion animals, and thus, we aimed to estimate the seroprevalence of SARS-CoV-2 in dogs and cats in Sarawak, Malaysia.

Ectopic orbital meningioma: Fact or fiction?

Primary intraorbital ectopic meningiomas are rare and their existence remains controversial. We present a 30-year-old female with painless, non-axial proptosis and a palpable superomedial mass. The MRI demonstrated that the mass had no optic nerve sheath or sphenoid wing involvement and was initially reported to have no intracranial extension.

Key Issues When Reconstructing Extensive Upper Eyelid Defects With Description of a Dynamic, Frontalis Turnover Flap.

Reconstruction of full thickness, total upper eyelid defects represents a significant challenge in terms of recreating an upper eyelid which has acceptable cosmesis and a degree of dynamic function. Options include bridging, eyelid-sharing techniques (e.g.

Clinical and Imaging Features of Lacrimal Gland Involvement in Granulomatosis with Polyangiitis.

Purpose: Lacrimal gland involvement in granulomatosis with polyangiitis (GPA) commonly accompanies orbital disease, but occasionally may be the sole presentation preceding any other organ manifestation or systemic disease. Diagnosis of orbital GPA, especially in patients with lacrimal involvement as the initial presentation, can be difficult because of nonspecific clinical features and lack of diagnostic specificity on histologic and antineutrophilic cytoplasmic antibody (ANCA) testing. Orbital GPA can be associated with a high morbidity from potential visual loss or rapid progression of latent systemic disease, making early diagnosis important.

Clinical and imaging features predictive of orbital granulomatosis with polyangiitis and the risk of systemic involvement.

Objective: Granulomatosis with polyangiitis (GPA), previously Wegener's granulomatosis, requires prompt diagnosis and systemic review to exclude life-threatening disease. However, early diagnosis of orbital GPA may be difficult because anti-neutrophil cytoplasmic antibody (ANCA) and anti-PR3 antibody screening can be negative at presentation and orbital biopsies taken for diagnosis may not show the classic features of GPA. This study was designed to compare GPA with other causes of orbital inflammation and to identify the presenting clinical and imaging features most likely to predict GPA and its systemic spread.

Acute glaucoma secondary to angle obstruction by triamcinolone crystals.

Purpose: To present a case of acute glaucoma secondary to massive transit of triamcinolone acetonide into the anterior chamber in a pseudophakic, vitrectomized eye following intravitreal injection for treatment of cystoid macular edema.

Setting: Manchester Royal Eye Hospital.

Method: Case study.

Asymptomatic snowflake degeneration in a polymethyl methacrylate (PMMA) intraocular lens implant.

Snowflake degeneration is a late complication of polymethyl methacrylate (PMMA) intraocular lens implants. We report a case of asymptomatic advanced snowflake opacification presenting 13 years after implantation who maintained a visual acuity of 6/6. This report serves to illustrate the variability of the clinical effects of snowflake degeneration, which do not necessarily correlate with slit-lamp appearances.

Should patients set the agenda for informed consent? A prospective survey of desire for information and discussion prior to routine cataract surgery.

Purpose: To ascertain the level of information relating to specific risks desired by patients prior to cataract surgery.

Setting: Dedicated cataract surgery pre-assessment clinics of 2 hospitals in South West Wales, UK.

Methods: Consecutive patients (106) were recruited prospectively.
