An untimely death
Tuesday, 29 March 2011
Patient with DKA
Madam PG is a 29 year old young woman with poorly controlled diabetes on oral hypoglycaemic agents for the past 2 years, who also has history of peptic ulcer disease and 2 recent admissions for diabetic ketoacidosis. She presented on the 21st of March 2011 with nausea and vomiting for 2 days associated with epigastric pain. During this period she was unable to tolerate orally and had not been able to take her medication. She had no symptoms suggestive of a respiratory or urinary tract infection. On admission she was moderately dehydrated and lethargic however she was not in respiratory distress. Her capillary blood glucose reading was 23.6 mmol/L and her vital signs were as follows: BP: 130/80, pulse: 110, temperature: 37.2C, respiratory rate : 20 and SPO2: 100% on room air. Her venous blood gases showed metabolic acidosis, her serum ketone level was 5.8 mmol/L and ketones were also detected in her urine. She was also noted to have a thyroid enlargement however she was clinically euthyroid. In the ward, she was treated with an intravenous insulin infusion, initiated at 6 units per hour (0.1units/kg/hour), and rehydrating fluids both of which were adjusted according to her blood glucose level. Potassium supplementation (1g/hr of KCL in each alternate bottle of fluid) was commenced on day 2 of admission when her K+ levels dropped from 4.5 mmol/L to 3.6 mmol/L. On day 5 of admission her general condition improved and she was no longer acidotic (VBG: no acidosis, serum ketones: 0). She was started on of s/c actrapid insulin in place of IV insulin and was discharged well on the 27th of March 2011 with s/c mixtard insulin and T. Metformin.
Issues in this case
From her diagnosis 2 years ago, Madam PG has been labeled as a type 2 diabetic. However, because of her young age, frequent episodes of DKA, poor diabetic control with OHAs as well as the associated clinical finding of a goiter, could Madam PG be a Type 1 diabetic instead? During clerking, it was also revealed that her mother was also diagnosed with type 2 diabetes at a relatively young age (in her early 30s), another fact in favour of type 1 DM. In the ward, the managing doctors considered ordering a C-Peptide measurement for her. However, it was not done as the rationale was that, whether she has type 1 or type 2 diabetes will not change the subsequent management because she will be started on insulin following this admission. Should more have been done for her in terms of diagnosis of type 1 DM? Would an autoimmune screen be necessary as she also has a thyroid enlargement?

Supply vs demand??
Patient, Madam SA, a 44 year old Malay lady was admitted on 15th of March for cramping over both upper limbs, lower limbs and neck.
It was due to hypocalcaemia that she has been having since 3 years ago. Patient was put on long term calcium supplement after a thyroidectomy in year 2008. She claimed that since the operation, she had frequent cramps and was told that she developed hypocalcaemia as a complication of that surgery and needed life-long calcium supplement and to hospital for monthly calcium Injection.
However, things did not go well as very often, the hospital claimed that they ran out of stock. Even with calcium supplement patient was still having cramps very often and with inadequate supply, her condition got worse. She claimed that she has hoarseness of voice as a result of the operation as well also. She has one son studying KL and seldom visits her as he is busy with his studies. Her husband passed away 10 years ago in an accident. She currently stays alone and had stopped working since her thyroidectomy 3 years ago.
She said that she was feeling very sad and hopeless because all she wanted at that time when she went for the surgery was to be euthyroid but she ended up having all these complications instead. She regretted going for the surgery and has depressive symptoms because of that.
Lets focus on her problems. Firstly, the operation itself. She came in for what she came was hyperthyroidism and ended up having hoarseness of voice and frequent cramps as a result.
She was put on calcium supplements but in the end, the supply ran out not once, but continuously. She also developed depression in the end.
From a high hope of actually treating her hyperthroidism, she ended up with cramps every now and then, hoarseness of voice and also depression.
The least we can do now is to try to find a way to help her on getting an uninterrupted supply of medication.
Any comments?? Ways to ensure she gets her medication?
In my opinion, we can try talking to the pharmacist, try to work this out. Buying from pharmacies by herself is difficult due top her financial constraint. Maybe hospital buy for her or maybe getting emergency supply from other hospitals?
Haematuria
Among the many other problems of his, he developed frank haematuria on the 2nd day of admission. He told the house officer but the medical team didn't seem to be bothered by it. The haematuria didn't stop and accumulated to about 200mls. This was his first episode of haematuria.
This could have been a few of many things, among which trauma from CBD insertion (although perhaps unlikely as he continued to bleed for a whole day), possibly from paraphymosis as he was also complaining of penile pain.
So, I decided to bring this to the attention of the doctor in charge as if the blood clots, this could lead to urinary obstruction resulting in further complications. However, the doctors dismissed it as statin myositis. Upon looking up his investigations that were done on admission (the day before), I found raised CK (3x upper limit), LDH and AST (both raised 2x upper limit), which could be in keeping with myositis. But from the simple knowledge that I have, I understand that even if it were truly statin myositis, it should not be dismissed as it could be fatal in some patients and that the statin should be withdrawn.
In my opinion, this case raises important issues surrounding professionalism and ethics as well as mismanagement and patient safety. What was further upsetting was that despite Mr. J having haematuria and complaining of groin pain, no one had examined the groin area. How could we have made a difference in the management of this Mr. J?
Treatment with Anticoagulants
Along with aspirin, sublingual glyceryl trinitrate (GTN) and oxygen therapy, a stat dose of fondaparinux was givin in the Accident & Emergency Department. His pain was relieved.
In the ward, he was treated with aspirin, simvastatin, isosorbide dinitrate, enalapril and metoprolol with sublingual GTN to use when necessary. Fondaparinux was replaced with clexane on the 2nd day of admission.
He developed no complications during his stay and serial ECG taking showed no further ischaemia. He was discharged on the 4th day of admission, to be reviewed in a month's time. Medications prescribed were aspirin, simvastatin, isosorbide dinitrate, enalapril, metoprolol and sublingual GTN. He was also referred for an echocardiogram.
Queries:
1. Why was fondaparinux replaced with clexane? I have observed that this is done quite regularly in the medical ward. If cost is the reason fondaparinux was replaced with clexane, why begin with fondaparinux initially?
2. Can these two anticoagulants be used interchangeably?

Patient With No Known Contacts
Post-Stroke Blood Pressure Control
Diagnosis: Acute Ischaemic Stroke with left-sided hemiparesis, with underlying hypertension and hyperlipidaemia
During admission, his blood pressure was 148/80mmHg. The patient was given tablet Amlodipine 5mg OD on the first day but withheld on the second day on the second day of admission.
Blood Pressure Control
In poor flow state as occurs with thrombotic ischaemic stroke, the cerebral vasculature is without vasoregulatory capability and thus relies directly on mean arterial pressure (MAP) to maintain cerebral blood flow. Therefore, aggressive efforts to lower blood pressure may decrease perfusion pressure and may worsen ischaemia.
I think this patient should not be given Amlodipine as his blood pressure was not high during admission. Antihypertensive agent may worsen cerebral ischaemia in acute ischaemic stroke.
Therefore, antihypertensive agent should only be given 2 weeks after the event.
What would the appropriate blood pressure control in this case?

Short case
On physical examination, he was cachexic looking. His hydration status was good. His apex beat was deviated. There was grade 2 diastolic mumur heard over the left lower sternal border and collapsing pulse was presence. however, he had no stigmata of infective endocarditis. There was tenderness over left lumbar and left iliac fossa. however, the abdomen was soft, no guarding and no hepatosplenomegaly.
His ECG showed left ventricular hypertrophy, T wave inversion at V1-6. Troponin-T and non specific cardiac enzymes were not elevated at the time of presentation. His FBC and renal profile were normal. Chest X-ray showed cardiomegaly and no other changes.
The other test results were not back.
He was treated as acute coronary syndrome and acute gastroenteritis (HIV related). He was also reffered to optalmologist for checking CMV retinitis.
On the next day, he requested to discharge. His chest pain resolved but still have minimal abdominal pain and diarrhoea. The doctor allowed him to discharge.
DO YOU AGREE WITH THE DOCTOR DECISION?
Case 3
This is a patient I saw last week in the male ward.
Mr A, a 60-year-old Chinese man, previously diagnosed with nasopharyngeal carcinoma 10 years ago and currently in remission for 5 years now, was admitted for chronic cough for 5 years. The cough started insidiously 5 years ago and at that time the sputum was greenish-whitish in colour. However, 2 years ago, he started having hemoptysis as well. The sputum coughed up now is thick blood mixed with mucus and about half cup to one cup each time. He also complains of intermittent low grade fever for the past 2 years and night sweats as well. He also has dizziness and headache after a bout of hemoptysis. However, he does not have any palpitations or fainting spells. He contracted nasopharyngeal cancer 10 years ago as he was working in a glue factory then. He had a growth in left nostril and completed radio and chemotherapy for it. He was told that his cancer was cured after completing therapy. He is under follow-up at Hospital Melaka for it. He currently has anosmia, reduced hearing but his sense of taste is still present. He does not have any TB contact and no other person staying with him has any similar signs and symptoms. He stays with his wife and his sister now. He is fully dependant on his wife and sister for income and housing as he lost his job at the glue factory as the factory closed down.
On examination, Mr A is alert, comfortable and cooperative. He cannot lie supine on his bed as he claims it will irritate his throat and cause him to cough. There is clubbing over all his fingers and toes. Capillary refill time is less than 2 seconds. However, he has pallor over his hands and conjunctiva. He does not have any jaundice. There is no signs of Horner's syndrome. Trachea was not deviated. On examination of his lungs, there is equal chest expansion of both lung fields. On tactile fremitus, there was increased resonance over the right middle and lower lobes of the lungs. On percussion, there was dullness over the right middle and lower lobes. On auscultation, there were normal vesicular breath sounds heard with no added sounds. On vocal fremitus, there was increased resonance over the right middle and lower lobes of the right lung as well.
Mr A had undergone many chest X-rays and CT scans over the past 5 years. The latest chest X-ray found a dense well-defined nodule in the right lower zone measuring about 3.5x2.5cm. CT scan in 2007 found consolidation of the right middle and lower lobe. Small bullae were seen within consolidation. AFB sputum was done in 2008 for one sample and was negative. ESR was also raised at 77. Full blood count showed hemoglobin 8.8 but other parameters were normal.
From the case, my differential diagnoses would be either a TB infection or a lung carcinoma, either primary or secondary from his previous nasopharyngeal carcinoma. Either way his symptoms are sinister and should not be allowed to drag on further. However, he was only admitted for less than 12 hours. He was treated with antibiotics for pneumonia and discharged with a follow-up visit to the MOPC 2 weeks later. The MO-in-charge thought of the above differential diagnoses but did not bother to take further action to investigate further. The official diagnosis written in the case notes was also pneumonia. The other symptoms were made light of. I feel that it is very unethical to just push the patient off and not bother about what will happen to him when he has already gone through so many prior investigations. Mr A was very desperate for someone to just listen to him and diagnose and treat him properly. Hopefully whoever who will see Mr A in the MOPC will attend to his symptoms properly and treat him as soon as possible.
