Sudden onset single floater symptom in one eye: is urgent dilated fundal examination by an ophthalmologist warranted?

A 60 year-old lady presents to the emergency department complaining of a 3 day history of a sudden onset single floater in her left eye with no history of flashing lights or other visual problems. Her visual acuity is 6/6 aided in each eye. Dilated fundal examination of her retina with a direct ophthalmoscope is unable to exclude peripheral retinal pathology. You wonder whether she needs specialist dilated fundal examination by an ophthalmologist to exclude a retinal tear or detachment?

Corticosteroids may be beneficial for infant outpatients with viral bronchiolitis

Parents bring their 10 month old, previously healthy infant to the ED after two days of fever, rhinorrhea, cough, and poor feeding. Today the infant is wheezing and has labored breathing.

Is cyclizine is better than metoclopramide in patients with moderate to severe abdomen pain

A 38 year old man presents to the emergency dept with moderate to severe abdomen pain. He requires intravenous morphine for pain and is complaining of feeling nauseous so you decide to give him an intravenous anti-emetic. However, you are concerned that intravenous metoclopramide can increase gastric emptying and contra- indication in intestinal obstruction. You wonder whether there is any evidence to support the fact that metoclopramide is detrimental to patients with moderate to severe abdomen pain.

No evidence found that a femoral nerve block in cases of femoral shaft fractures can delay the diagnosis of compartment syndrome of the thigh.

A 30 year old man is brought into A&E following a bicycle accident. He is complaining of agonizing pain in his Right thigh. On examination his thigh is very swollen and any attempt to move it is extremely painful. You suspect a femoral shaft fracture and want to administer some strong analgesia and a splint and send him for x-ray. The orthopaedic registrar complains that a femoral block could potentially mask the symptoms of a compartment syndrome. You are wondering if there is any evidence to support this.

Smectite in Acute Diarrhoea

A 12-month-old boy with acute diarrhea is brought to the emergency department by his parents. He tolerates oral rehydration solution well but his parents still worry very much about his frequent loose stools. You wonder if the use of smectite would provide any additional benefit.

Calcium and vitamin D3 in osteoporotic fractures

Mrs. S, a 72-year-old female retired piano teacher presented to the AECC clinic with a 30-year history of upper cervical stiffness. She has had a history of corticosteroid use and had early menopause. Mrs. S has also not had any HRT. Cervical series of x-rays were taken, which showed generalised osteopaenia throughout the cervical spine. Mrs. S was referred for a DXA bone scan, which revealed a bone density of 2.2SD (standard deviation) below normal. Mrs. S is being treated with general mobilisation and myofascial therapy of the cervical spine. She asks your advice on whether supplements could be beneficial.

A new CURE? Clopidogrel ahead of coronary angioplasty in acute coronary syndromes

A thirty-five year-old man has presented with 12 hours of chest pain. ECG shows widespread T wave inversion and troponin T is 1.0. In view of his ongoing chest pain and young age the cardiologists decide to perform immediate angioplasty. You have given aspirin, oxygen, nitrates and morphine. As he is about to go for angioplasty, you wonder if a loading dose of clopidogrel will still confer any added benefit.

Atropine as a pre-procedure medication in elective pleural aspiration

A 24 yr old, otherwise fit and health student presents to the ED with pleruritic chest pain and shortness of breath. On examination he has absent breath sounds in the upper zone on the right side of his chest and his chest X ray confirms your clinical suspicion of a spontaneous pneumothorax. You decide to aspirate the pneumothorax. You have heard that this procedure may cause a vasovagal sycope and wonder whether this may be prevented by a injection of atropine prior to the procedure.

The treatment for a popliteal (Baker’s) cyst

A 53years old man is referred to physiotherapy with a painful, intact Baker's cyst. His knee is painful and swollen posteriorly, though not warm to the touch and has limited RoM of flexion and extension. In the absence of any firm treatment guidelines, you wonder if there is any additional benefit from using ICE and cryotherapy to reduce the popliteal swelling.

The effect of physiotherapy on myositis ossificans

A 28 years old man is referred to physiotherapy with a clinical and radiographic diagnosis of myositis ossificans 3 months after direct trauma to his right quadriceps muscle. He only has about 450 of right knee flexion and severe pain in the right thigh. You wonder whether an aggressive knee mobilisation regime rather than a more conservative approach might be beneficial to improve function quicker.

The effect of physiotherapy on hypersensitive post-operative scars

A 50 years old lady is 3 months post surgery to the wrist for Carpal Tunnel Syndrome. Although her previous symptoms related to CTS have resolved and her wound is well healed, her recovery has been hindered by a hypersensitive surgical scar. Consequently, she is referred to physiotherapy to help resolve these symptoms where there are mixed views about whether electrotherapy or a more manual form of therapy is the best technique for desensitising the scar.

Anticoagulation for acute ischaemic limbs

A 62 year old man with a longstanding history of peripheral vascular disease and atrial fibrillation presents to the emergency department with a 2 hour history of severe pain in the left forefoot. Examination reveals a cool, pale, pulseless left foot. You wonder whether low molecular weight or unfractionated heparin is better in this patient.

Is it my heart, doctor? Placental growth factor for detection of cardiac chest pain

A fifty year-old man presents with tight central chest pain for thirty minutes. There are no abnormalities on physical examination and his initial ECG is normal. He asks, "Is it my heart, doctor?". You explain that you cannot be certain but will do a blood test to make sure he hasn't had a heart attack in twelve hours time. He looks confused. You wonder why the triage of cardiac chest pain is still so difficult in the 21st century. Surely there is a better way of excluding acute coronary syndromes. Having heard about placental growth factor as a promising cardiac biomarker, you wonder if there is any evidence that it would be useful in this situation.

Can the use of thromboelastography predict and decrease bleeding and blood and blood product requirements in adult patients undergoing cardiac surgery?

You start work in a new unit which routinely uses thromboelastography to manage coagulopathy and guide treatment with blood component therapy following surgery. As you have no experience of the technique you decide to review the literature to identify whether the technique is actually beneficial in decreasing exposure to allogeneic blood and blood component therapy.

Can ventilation while on cardiopulmonary bypass improve post-operative lung function for patients undergoing cardiac surgery?

You are about to perform four coronary arterial bypass grafts on a 78-year-old ex steel worker. He has a 60 pack per year history of smoking and his lung function tests are significantly abnormal with an FEV1 only 40% of his predicted values. His coronary arterial targets are small and you feel that an on-pump technique is the only option. You discuss the case with the anaesthetist and he asks whether he could keep ventilating while the patient is on bypass in order to improve his post-operative lung function. You have significant concerns that this may make the case even more difficult but rather than refusing this request you resolve to search the literature for evidence that this will improve post-operative lung function as your anaesthetist suggests.

Is sympathectomy of benefit in critical leg ischaemia not amenable to revascularisation?

You recently admitted an 82-year-old arteriopath who has had an 8-month history of critical leg ischaemia and who has debilitating pain at rest. Lower limb arteriogram confirms three-vessel disease not amenable to revascularisation. A below knee amputation was discussed with the patient. The patient asks you if anything could be done rather than an amputation. You have heard of sympathectomy, but wanted to confirm from the literature that this may be a viable option.
