Q

Radiotherapy in breast cancer?

A

Whole breast radiotherapy is recommended after a woman has had a wide-local excision as this may reduce the risk of recurrence by around two-thirds. For women who’ve had a mastectomy radiotherapy is offered for T3-T4 tumours and for those with four or more positive axillary nodes

Q

Hormonal therapy for breast cancer?

A

Adjuvant hormonal therapy is offered if tumours are positive for hormone receptors. For many years this was done using tamoxifen for 5 years after diagnosis. Tamoxifen is still used in pre- and peri-menopausal women. In post-menopausal women, aromatase inhibitors such as anastrozole are used for this purpose*. This is important as aromatisation accounts for the majority of oestrogen production in post-menopausal women and therefore anastrozole is used for ER +ve breast cancer in this group.

Q

Renal stones Initial Rx?

A

Stones < 5 mm will usually pass spontaneously. Lithotripsy and nephrolithotomy may be for severe cases.

Most renal stones measuring less than 5mm in maximum diameter will typically pass within 4 weeks of symptom onset. More intensive and urgent treatment is indicated in the presence of ureteric obstruction, renal developmental abnormality such as horseshoe kidney and previous renal transplant. Ureteric obstruction due to stones together with infection is a surgical emergency and the system must be decompressed. Options include nephrostomy tube placement, insertion of ureteric catheters and ureteric stent placement.

174
Q

Therapeutic selection for renal stones?

A
  1. Ureteric calculi <5mm = manage expectantly
  2. Complex renal calculi and staghorn calculi = percutaneous nephrolithotomy
  3. Stone burden of less than 2cm in aggregate = lithotripsy
  4. Stone burden of less than 2cm in pregnant females = ureteroscopy
175
Q

ESWL process?

A

A shock wave is generated external to the patient, internally cavitation bubbles and mechanical stress lead to stone fragmentation. The passage of shock waves can result in the development of solid organ injury. Fragmentation of larger stones may result in the development of ureteric obstruction. The procedure is uncomfortable for patients and analgesia is required during the procedure and afterwards.

176
Q

Ureteroscopy process?

A

A ureteroscope is passed retrograde through the ureter and into the renal pelvis. It is indicated in individuals (e.g. pregnant females) where lithotripsy is contraindicated and in complex stone disease. In most cases a stent is left in situ for 4 weeks after the procedure.

177
Q

Percutaneous nephrolithotomy procedure?

A

In this procedure, access is gained to the renal collecting system. Once access is achieved, intra corporeal lithotripsy or stone fragmentation is performed and stone fragments removed.

2. +/- digital subtraction angiogram (catheter angiogram)

194
Q

SAH Rx?

A

Depends on causative pathology
1. Intracranial aneurysms are at risk of rebleeding and therefore require prompt intervention, preferably within 24 hours
2. Coiling by interventional radiologist
3. Craniotomy and clipping by BSX
4. Until the aneurysm is treated, the patient should be kept on strict bed rest, well-controlled blood pressure and should avoid straining in order to prevent a re-bleed of the aneurysm
5. Vasospasm is prevented using a 21-day course of nimodipine (a calcium channel inhibitor targeting the brain vasculature) and treated with hypervolaemia, induced-hypertension and haemodilution
6. Hydrocephalus is temporarily treated with an external ventricular drain (CSF diverted into a bag at the bedside) or, if required, a long-term ventriculo-peritoneal shunt

195
Q

Complications of aneurysmal SAH?

215
Q

Superficial thrombophlebitis mushkies?

A

Superficial thrombophlebitis, as the name suggests describes the inflammation associated with thrombosis of one of the superficial veins, usually the long saphenous vein of the leg. This process is usually non-infective in nature but secondary bacterial infection may rarely occur resulting in septic thrombophlebitis.

Around 20% with superficial thrombophlebitis will have an underlying deep vein thrombosis (DVT) at presentation and 3-4% of patients will progress to a DVT if untreated. The risk of DVT is partly linked to the length of vein affected - an inflammed vein > 5 cm is more likely to have an associated DVT.

  3. No observed respiratory effort in response to disconnection of the ventilator for long enough (typically 5 minutes) to ensure elevation of the arterial partial pressure of carbon dioxide to at least 6.0 kPa (6.5 kPa in patients with chronic carbon dioxide retention). Adequate oxygenation is ensured by pre-oxygenation and diffusion oxygenation during the disconnection (so the brain stem respiratory centre is not challenged by the ultimate, anoxic, drive stimulus)
219
Q

Brainstem death testing done by?

268
Q

Priapism Ix?

A
  1. Cavernosal blood gas analysis to differentiate between ischaemic and non-ischaemic: in ischaemic priapism pO2 and pH would be reduced whilst pCO2 would be increased
  2. Doppler or duplex ultrasonography: this can be used as an alternative to blood gas analysis to assess for blood flow within the penis.
  3. A full blood count and toxicology screen can be used to assess for an underlying cause of the priapism.
  4. Diagnosis of priapism is largely clinical, with investigations helping to categorise into ischaemic and non-ischaemic as well as assessing for the underlying cause.
269
Q

Priapism Rx?

A
  1. Non-ischaemic = not a medical emergency and is normally suitable for observation as a 1st line option
  2. Ischaemic = medical emergency. If the priapism has lasted longer than 4 hours, the first-line treatment is aspiration of blood from the cavernosa, this is often combined with injection of a saline flush to help clear viscous blood that has pooled. If aspiration and injection fails, then intracavernosal injection of a vasoconstrictive agent such as phenylephrine is used and repeated at 5 minute intervals. If medical therapy fails then surgical options can be considered

Q

Malignant hyperthermia?

A

A rare, serious side effect of volatile liquid anaesthetics (isoflurane, desflurane, sevoflurane), which cause all skeletal muscle to rapidly contract, including during a neuromuscular blockade. MH is a genetic disorder, manifesting due to calcium overload in the skeletal muscle causing sustained muscular contraction and rhabdomyolysis, resulting in excess anaerobic metabolism causing acidosis. End-tidal CO2 increases as a result, along with body temperature which causes diaphoresis (excess sweating)
