The patient likely has celiac’s disease, but if she has been avoiding gluten, a biopsy may be negative. Even though a biopsy is the gold standard for diagnosis, she will need to re-introduce gluten into her diet prior to undergoing the biopsy.

Vitamin deficiencies can happen in alcoholics due to malabsorption. Vitamin C deficiency or scurvy can result in bleeding gums and early symptoms including body weakness and lethargy. Other vitamin deficiencies can cause the following:
B1 or thiamine – Wernicke’s encephalopathy
B12 or cyanocobalamin – spinal cord degeneration
Vitamin K – anticoagulant effects
Vitamin E – neuropathies.

Extended-spectrum beta-lactamases (ESBL) are enzymes that confer resistance to most beta-lactam antibiotics, including penicillins, cephalosporins, and the monobactam aztreonam. Extended spectrum beta-lactamase (ESBL) production is the main reason for multi-drug resistance among E.coli. Commonly used medications to treat ESBL-involved infections include carbapenems (imipenem, meropenem, and doripenem), cephamycins (cefoxitin and cefotetan), Fosfomycin, nitrofurantoin, beta-lactamase inhibitors (clavulanic acid, tazobactam, or sulbactam), non-beta-lactamases and colistin (if all other medications have failed.)

The respiratory depression and miosis in this patient indicate opiate poisoning. For this, the best treatment is naloxone.

The development of hepatic fibrosis reflects an alteration in the normally balanced processes of extracellular matrix production and degradation. [6] The extracellular matrix, the normal scaffolding for hepatocytes, is composed of collagens (especially types I, III, and V), glycoproteins, and proteoglycans. Increased collagen in the space of Disse (space b/w sinusoids and hepatocytes) leads to capillarization of sinusoids, and stellate cells also have contractile properties when activated. This is fibrosis processes. This can lead to the development of portal hypertension.

Ankylosing spondylitis (spondylarthritis) is a chronic inflammatory disease of the axial skeleton that leads to partial or even complete fusion and rigidity of the spine. Males are disproportionately affected and upwards of 90% of patients are positive for the HLA-B27 genotype, which predisposes to the disease. The most characteristic early finding is pain and stiffness in the neck and lower back, caused by inflammation of the vertebral column and the sacroiliac joints. The pain typically improves with activity and is especially prominent at night. Other articular findings include tenderness to percussion and displacement of the sacroiliac joints (Mennell’s sign), as well as limited spine mobility, which can progress to restrictive pulmonary disease.
The most common extra-articular manifestation is acute, unilateral anterior uveitis. Diagnosis is primarily based on symptoms and x-ray of the sacroiliac joints, with HLA-B27 testing and MRI reserved for inconclusive cases. There is no curative treatment, but regular physiotherapy can slow progression of the disease. Additionally, NSAIDs and/or tumour necrosis factor-? inhibitors may improve symptoms. In severe cases, surgery may be considered to improve quality of life. The spine adopts a bamboo shape, not lordosis. The pain usually improves as the day progresses. leg raise test causes pain in cases of meningitis etc not in this case.

A formula for estimating glomerular filtration rate (eGFR) is the Modification Diet of Renal Disease (MDRD) equation which takes into account the following variables: serum creatinine, age, gender, and ethnicity. Thus, serum urea is not required in this formula.

ERCP is necessary to look for any obstruction or compression of the extra-hepatic bile duct. The clay-coloured stools are a result of impaired bilirubin movement into the duodenum.

Spironolactone is an aldosterone antagonist diuretic that is well-known to cause gynaecomastia because it increases testosterone clearance and oestradiol production. The patient’s primary complaint of gynaecomastia should immediately prompt discontinuation of spironolactone and replacement with Eplerenone, which lacks the antiandrogenic effects, and thus there is less risk of gynaecomastia.

Myotonic dystrophy is the most likely diagnosis here.
It is a multisystem disorder causing cognitive impairment, cataracts, cardiac problems and testicular atrophy, as well as affecting the muscles. Patients have muscle weakness, normally worse distally, and/or myotonia (which is worse in cold weather).
On examination, patients may also have frontal balding, a myopathic facies, bilateral ptosis, an ophthalmoplegia and wasting of facial muscles and other limb muscles. Myotonic dystrophy is associated with diabetes mellitus and pituitary dysfunction.
Diagnosis is normally based on clinical features with a characteristic electromyogram (EMG) of myotonic discharges. Creatine kinase is generally normal and muscle biopsy is non-specific.
