Diabetic neuropathic cachexia associated with malabsorption.

Diabetic neuropathic cachexia is characterized by neuropathic pain and severe weight loss of unknown aetiology. We describe four patients with diabetic neuropathic cachexia who were found to have malabsorption. Four diabetic patients presented with neuropathic pain, anorexia, depression and weight loss of 16 (range 10-21) kg. None complained of diarrhoea. There were three males and one female, median age 54 (46-67) years. A butterfat test showed a serum turbidity difference of 9 (6-10) light scattering units (normal greater than 60 units). The median serum xylose was low and there was delayed urinary xylose excretion. Urinary indicans, small bowel histology, liver function tests, and thyroid and renal function were normal. Ultrasound scans of liver, gall bladder and pancreas, and endoscopic retrograde cholangiopancreatogram were normal. The patients were treated with pancreatic supplements and a high calorie diet. Three have completely recovered and the other patient is improving. Thus these cases of diabetic neuropathic cachexia appeared to be associated with malabsorption which may be due to pancreatic dysfunction. It is suggested that the management of diabetic neuropathic cachexia should include the investigation and treatment of malabsorption.

The apomorphine test in parkinsonian syndromes.

The dopamine receptor agonist apomorphine has been used successfully to treat on-off swings in Parkinson's disease. Its value as a predictor of dopa responsiveness in idiopathic Parkinson's disease (IPD) was assessed and its potential role in differentiating IPD from the Parkinsonian plus syndromes (PPS) of multisystem atrophy, progressive supranuclear palsy and olivopontocerebellar atrophy was investigated. The response to an injection of apomorphine was observed in 20 patients with IPD and eight with PPS after being off levodopa for 12 hours. Patients were reassessed after taking levodopa for one month. Nineteen of the 20 patients (95%) with IPD showed a positive response to apomorphine and 18 (90%) to oral levodopa. In the PPS group, two patients (25%) responded to the apomorphine injection but not to oral levodopa. Apomorphine produced severe drowsiness in the PPS patients. It is suggested that the test can predict dopa responsiveness in IPD and may be of help in confirming a doubtful diagnosis. It has potential value in differentiating IPD from PPS.

Low dose botulinum toxin in spasmodic torticollis.

Botulinum toxin has been successfully used to treat spasmodic torticollis. The optimum dosage is not clear and the recommended doses in the United Kingdom are 20-25 ng. We have used much lower doses (average 13 ng) without loss of efficacy and accompanied by a reduction in side effects. We treated 12 patients (eight women and four men) with a mean duration of torticollis of 4 years. Eleven of the 12 patients (91%) showed an improvement in total scores for pain and degree of head movement. The benefits appeared a week after treatment and lasted for 3 months. Side effects were minimal and transient. Our experience suggests low doses of the toxin may be equally efficacious.

Multiple sclerosis associated with water intoxication.

We present a case of well documented multiple sclerosis which presented with the syndrome of inappropriate antidiuretic hormone secretion, following an exacerbation of the disease. This is a poorly documented association.

Multiple sclerosis associated with trismus.

This report describes the case history of a middle-aged lady who presented with symptoms and signs over one year leading to a diagnosis of multiple sclerosis. During one of her relapses, she developed trismus--an association that has not been described before in multiple sclerosis.

Coarctation of the aorta associated with a sinus venosus atrial septal defect presenting with endocarditis in middle age.

We report the case of a 44 year old man who presented with an infective endocarditis and was found to have a coarctation of the aorta associated with a sinus venosus atrial septal defect and a small ventricular septal defect. The association of coarctation with a sinus venous atrial septal defect presenting with endocarditis in an adult is extremely rare.

Bilateral subdural haematomas and normal CT brain scans.

We describe the case of a 59-year-old man who presented with headaches suggestive of raised intracranial pressure. He had a normal computerised tomographic (CT) scan on two occasions over a period of two months during which time he continued to deteriorate. Eventually, a magnetic resonance imaging (MRI) scan showed the presence of bilateral subdural haematomas. This case thus illustrates that normal CT scans may not exclude an intracranial pathology--and, if in doubt, an MRI scan should be sought.

ACE inhibitors and diuretics causing hypokalaemia.

Angiotensin-converting enzyme (ACE) inhibitors and diuretics are known to cause hyperkalaemia. We undertook a prospective analysis over a period of six months of patients admitted under our care. Of 217 patients, 39 (18 per cent) were admitted with congestive cardiac failure/left ventricular failure. Of these 39 patients, 21 (54 per cent) were prescribed ACE inhibitors. Seven of these 21 patients subsequently developed hypokalaemia. This was irrespective of the type or dose of the diuretic but seemed to be related to the dose of the ACE inhibitor. In three cases the hypokalaemia was corrected by the addition of a potassium-sparing diuretic; in two cases a potassium supplement was added; and in the other three an increase in the dose of the ACE inhibitor for the resistant heart failure corrected the potassium deficit. This study shows that one should be alert to both hyperkalaemia and hypokalaemia when using a combination of ACE inhibitors and diuretics.
