In our study, we demonstrated that central venous ports and PICC lines in patients undergoing infusional chemotherapy had lower line infection rates than tunnelled catheters, and only ports have been shown to be almost complication-free. In addition, we found infection rates higher in CVCs s cared for by patient/carers rather than hospital only care, and higher in colorectal patients with stomas. Therefore, we recommend that central venous ports are a safe, acceptable CVC option for infusional chemotherapy for adults with solid tumours.

Acute localized scleroderma (morphea) can present as severe generalized oedema with rapid weight gain and oliguria. The putative mechanism is increased capillary permeability. CASE HISTORYA woman of 67 was referred to the renal service for investigation of severe and increasing peripheral oedema which had not responded to treatment with diuretics. Her weight had risen by 12 kg in a few weeks. On close questioning she indicated that the skin of her swollen legs had become abnormal in texture, 'hard', and she had also noticed hardening of the skin of the forearms and lower abdomen. 7 years previously seronegative rheumatoid arthritis had been diagnosed, mainly affecting her hands; this had responded to weekly methotrexate, which she was still taking.There was sacral and pretibial oedema, with abdominal swelling; the lungs were normal and jugular venous pressure was not raised. She had striking dermatographia, acrosclerosis and hardening of the skin of both legs. Dipstick testing of urine revealed neither proteinuria nor haematuria. On admission, plasma sodium was 138 mmol/L, potassium 3.9 mmol/L, albumin 28 g/L, urea 4.7 mmol/L and creatinine 76 mmol/L. C-reactive protein was 70 mg/L. Haemoglobin was 11.9 g/L with normal white cell count and differential; platelet count was 454Â10 9 /L. Results of the following were all normal: plasma glucose, calcium, phosphate, bilirubin, alanine aminotransferase, alkaline phosphatase, immunoglobulins and protein electrophoresis, and complement C3 and C4; clotting tests; thyroid function tests; bone marrow biopsy; and abdominal CT scan (apart from generalized oedema). An echocardiogram showed normal left ventricular function but there was some dilatation of the right ventricle with moderate tricuspid regurgitation. Initial urine volume was only 500 mL/day, though creatinine clearance was normal. Albuminuria remained undetectable, but she had tubular proteinuria; 24-hour urinary sodium excretion was very low (12 mmol/24 h) and remained so for several weeks; urine osmolality was 982 mosm/kg, with plasma osmolality 294 mosm/kg. Colloid oncotic pressure was slightly reduced at 19 mmHg (normal range 20-23). After admission she gained a further 20 kg (about 1 kg/day), despite fluid restriction. Further investigations showed serum aldosterone normal, renin about twice the upper limit of normal, rheumatoid factor negative, antinuclear antibody (ANA) weakly positive at 1:20, anti Ro, La, Sm, RNP, Jo-1 and SCL070 all negative. Urinary cortisol was normal.A diagnosis of morphea was suggested and was confirmed by skin biopsies. She was treated first with methylprednisolone, then with oral steroids and a trial of penicillamine. The skin disorder stabilized and the oedema subsided over a few months. Renal function, which did not change during the hospital admission, remained stable during 2 years of follow up with plasma creatinine around 90 mmol/L and an isotopic glomerular filtration rate of 60 mL/min/m 2 . She has required treatment for hypertension, currently well controlled on two drugs....

Severe acute headache is a common presenting symptom to an accident and emergency department. Spontaneous intracranial hypotension (SIH) is an increasingly recognised cause of these symptoms and has characteristic clinical and imaging findings. SIH is characterised by headache worse on standing, low opening cerebrospinal fluid pressures at lumbar puncture and uniform pachymeningeal enhancement with gadolinium enhanced magnetic resonance imaging of the brain, all in the absence of dural trauma. Atypical presentations occur and severe neurological decline can rarely be associated with this condition. A review of five patients presenting recently to our institution with classical imaging findings together with a review of the literature is presented.

A 39-year-old woman presented to the maxillofacial clinic of the authors' institution with a 2-year history of pain in the right side of the throat radiating to the right face and ear. On clinical examination, there was scarring in the anterior pillar of the fauces, more prominent on the right side. There was no ulceration or palpable neck mass. The temporomandibular joints were normal. The patient gave a history of tonsillectomy 19 years ago. An orthopantomogram (Figure 1) demonstrated elongated styloid processes bilaterally, measuring 4.4 cm on the right and 4 cm on the left. Palpation of the styloid process following review of the orthopantomogram resulted in exacerbation of the patient's symptoms on the right side. Unenhanced computed tomography (Figure 2) of the neck confirming the clinical diagnosis of elongated styloid process or Eagle's syndrome. The patient underwent right-sided styloidectomy through an intra-oral approach. She was symptom free at 1 year follow-up.
