tb meds
I eat perfect rice
Isoniazid.
Rifampin
Ethambutol
Pyrazinamide.
tertiary hyperparathyroidism signs
Raised alkaline phosphatase levels
This is due to increased bone turnover (osteoblastic activity in particular) as a result of raised parathyroid levels. It is likely this patient has progressed from secondary to tertiary hyperparathyroidism, as persistent secondary hyperparathyroidism leads to autonomous production of parathyroid hormone, regardless of negative feedback from calcium levels.
prolonged PR interval
1st-degree heart block is caused by a delay in conduction from the SA node into the ventricles. As the AV node is supplied by the right coronary artery in 85% of individuals, disease in this artery may lead to first-degree heart block.
Acute Kidney Injury(AKI) and treatment
increase in serum creatinine of 26 μmol/L within 48 hours or an increase in serum creatinine ≥1.5 times above baseline value within 1 week or urine output of <0.5 ml/kg/hr for > 6 consecutive hours.
dialysis
signs of asthma
Tachypnoea- fast breathing
Hyperinflated chest
Hyper-resonance on chest percussion
Investigations in chronic asthma
Spirometry: FEV1/FVC <0.7 (obstructive spirometry)
Bronchodilator reversibility tests: Improvement of FEV1 >12% after bronchodilator therapy is diagnostic
Investigations in acute asthma
ABG: type 2 respiratory failure (low PaO2 and high PaCO2) is a sign of a life-threatening attack.
Routine blood tests (including FBC, CRP): to look for precipitating causes of an asthma attack, such as an infection.
Chest x-ray: to exclude differentials and possibly identify a precipitating infection.
asthma drugs
SABA
+ICS- beclometasone, Prednisolone, hydrocortisone
+LABA- salmeterol
+ Trial oral leukotriene receptor antagonist,/monelukast high-dose steroid, oral B2-agonist
tumours of the caecum and ascending colon
right hemicolectomy
tumours of the distal transverse colon and descending colon
left hemicolectomy
tumours of the sigmoid colon.
sigmoid colectomy
tumours >8 cm from the anal canal or involving the proximal 2/3 of the rectum
Anterior resection
tumours <8 cm from the anal canal or involving the distal 1/3 of the rectum.
Abdomino-perineal (AP) resection
Hepatic Adenoma surgery
<5cm or reducing in size - annual MRI
>5cm or increase in size - for surgical excision
HCC surgery
<2cm
peripheral lesions adenocarcinoma of the lung diagnosis
CT chest abdomen pelvis
then
biopsy would be the next investigation to carry out after a CT CAP to provide a definitive diagnosis. As this is a peripheral lesion it will most likely be obtained via transthoracic needle aspiration.
falls and elderly
Use the Fracture Risk Assessment Tool (FRAX)
This patient is elderly and clearly has a high falls risk, making her liable to have an osteoporotic fracture in the future. The FRAX score offers a formal way to quantify this risk, and if it is above a certain threshold, bisphosphonates should be given. If the risk is low, bisphosphonates do not need to be given, but if the risk is between the two extremes, a DEXA scan should be carried out to guide the need for bisphosphonates.
ramipril side effects
Ramipril causes hyperkalaemia by blocking the aldosterone pathway thereby leading to a retention of potassium.
2 week worsening SoB, stiffness and pain in wrists and fingers, particularly in the morning
dullness to percussion at the right lung base with associated reduced breath sounds
tenderness and boggy swelling at the metacarpo-phalangeal joints bilaterally.
Pleural fluid glucose <3.3 mmol/L
This is the correct answer. The patient presents with a pleural effusion, most likely an extra-articular manifestation of underlying rheumatoid arthritis. Almost 100% of effusions due to rheumatoid arthritis have low glucose levels.
absolute contraindication for diagnostic laparoscopy?
On warfarin with an INR of 2.8
An abdominal aortic aneurysm risks vascular rupture if not directly visualized. However, it is a relative contraindication rather than absolute.
MI and can’t get PCI till 2h and intracranial haemorrhage history
treatment
However, they have a previous intracranial haemorrhage which is an absolute contra-indication for fibrinolysis so PCI is the best option even if outside of the typical window.
diarrhoea after Bangladesh . He describes it as rice water looking and has also been vomiting.
and treatment
lassical description of a cholera infection. It is a Gram-negative aerobic bacterium. It is very rare or extinct in the western world, however in developing nations still exists. It is found in faecally contaminated water. It causes profuse watery diarrhoea and is treated with oral rehydration salts and fluids. Antibiotics can be given if the infection is severe, which lessens the severity and shortens the disease lifespan.- Doxycycline or co-trimoxazole)
Salmonella enterocolitis symptoms
t presents with diarrhoea, fever and cramps (usually within 12-36 hours of exposure). It can cause sepsis or meningitis, as well as septic arthritis.
fatigue, easy bruising, and tooth loss
multiple ecchmoses at non-traumatic sites, perifollicular haemorrhages, coiled hairs, and gingival swelling.
vitamin C deficiency. Refugee populations are at particular risk. There is a risk of intracerebral and endocardial haemorrhage,
5kg weight loss over the last 5 weeks and malaise
He also reports dark-coloured urine. He has a past medical history of familial adenomatous polyposis, for which he had a proctocolectomy 8 years ago.
On physical examination he is cachectic and there is scleral icterus.
Duodenal cancer
This is the correct answer. Patients with familial adenomatous polyposis (FAP) not only have a high risk of colorectal cancer, but are also at increased risk of duodenal cancer. Duodenal cancer is the 2nd highest cause of cancer death in FAP. Duodenal cancer can present with weight loss, nausea/vomiting, abdominal pain, and obstructive jaundice.
Mitral regurgitation
produces a pansystolic murmur that is heard best over the apex.
aortic stenosis
presents with syncope, shortness of breath and angina. It also produces an ejection systolic murmur heard best over the upper right sternal edge.
how to calc units
Units = strength % x volume (ml) ÷ 1000
Plummer Vinson Syndrome
triad of dysphagia, iron deficiency anaemia and glossitis/ inflamed tongue
Peutz-Jeghers syndrome
autosomal dominant
hamartomatous polyps in the GIT
pigmented lesions on the lips, face, palms and soles.
GI bleeding secondary to these polyps, and have an increased risk of developing gastric cancer. Management tends to be conservative, unless complications arise.
