Mitochondria are complex dynamic intracellular organelles that are responsible for many aspects of muscle metabolism, including energy production via the Krebs cycle, fatty acid beta oxidation, and the respiratory chain and oxidative phosphorylation system; calcium homeostasis; cell signalling via the generation of reactive oxygen species; and regulation of apoptotic cell death. This lecture will discuss muscular phenotypes related to mitochondrial dysfunction, including ocula...

We present a case series of patients admitted to our hospital with various manifestations of Cushing’s. 71 male, known type 2 diabetes, hypertension referred for adrenal incidentaloma. Cushingoid features with non suppressed ACTH. Low dose dexamethasone test (LDSST): no suppression. 4 cm pituitary microadenoma (likely co-secretory as gonadotropins elevated). Offered IPSS and pituitary surgery. Declined the same due to fears of COVID opted for medical therapy with metyrapo...

Traditional literature agrees that Diabetic Ketoacidosis is typically associated with Type 1 Diabetes Mellitus, but can be associated with stress including infections in Type 2 diabetics. The authors did a restrospective evaluation of diabetic ketoacidosis presenting to a large district hospital in London. 343 patients were admitted with diagnosis of Diabetic Ketoacidosis during the COVID peaks from January 2020 to January 2021. 57% of these were Type 1 diabetics and 43% were ...

Disorders of sodium metabolism in sarcoidosis are predominated by diabetes insipidus; SIADH is extremely rare, restricted to sporadic case reports. We present the case of a 68 year old South Asian female presenting with a 3 year history of chronic, mild hyponatraemia, which was asymptomatic apart from mild lightheadedness. She had a history of stable sarcoidosis that was not requiring treatment, based on lung pathology. Despite fluid restriction, serum sodium remained around 1...

Introduction: Reproductive health is closely related with nutritional status of a country. Nutritional problems are different between developed and developing countries. In the context of Bangladesh there is no recent assessment. This study aims to assess the nutritional status and reproductive morbidity among women in Dhaka city.Description of methods: A cross-sectional study was performed in 400 women, aged 15–40 years, in Dhaka city. Sample was s...

Aims This is an investigation of potential oxidative effects of AGE in response to the antioxidant glutathione in cultured human gingival fibroblasts, using radiolabelled steroids as substrates and their product 5 alpha dihydrotestosterone (DHT) as a marker of wound healing.Methods Confluent monolayer cultures of human gingival fibroblasts were incubated with 14C-Testosterone and 14C-4-androstenedione respect...

Aims Nicotine (N) has detrimental effects on fibroblasts compounding those of AGE in uncontrolled diabetes. The impact of the antioxidant glutathione (G) is investigated to clarify mechanisms involved, using 5 alpha dihydrotestosterone (DHT) as a hormone marker of healing.MethodsHuman gingival fibroblasts in confluent culture were incubated in Eagle’s MEM, with 14C-testosterone / 14C-4-androstenedione an...

The association between hypomagnesaemia and proton pump inhibitors (PPIs) has been well-established in recent years, with a median onset of electrolyte disturbance around 5.5 years after PPI initiation. The mechanisms and aetiology of this potentially life-threatening side-effect remain unclear. We assessed the prevalence of PPI usage in all cases of severe hypomagnesaemia (defined for the purposes of the study as a magnesium level <0.4 mmol/l) in our hospital over the cou...

Prolactinomas are the most common functional pituitary tumours. Therapy is with dopamine agonists (DA). Cabergoline is frequently used as a first line agent; resistance to therapy is seen to other DA. We present a case of a 32 year old woman who moved to our area in the 1st trimester of pregnancy. She was known to have macroprolactinoma (maximal diameter > 1 cm), impinging on the optic chiasm. She was on cabergoline 0.5 mg once daily, but this was discontinued with no complica...

We present a case of a 50 year old patient with sepsis and a significant and symptomatic hypercalcaemia of 3.38 mmol/l with a background of MS. The infection responded to treatment however the hypercalcaemia persisted despite appropriate measures. Further investigation showed a suppressed PTH, normal ACE level, electrophoresis and 25(OH) vitamin D level, but found her to be thyrotoxic with TSH suppressed at <0.01, free T4 – 37.2 nmol/l, free T3 – 212 nmol/l. She ...
