A rare aberrant distal branch preventing complete internal carotid artery occlusion.

A 72-year-old man presented with a 3-day history of recurrent transient ischaemic attacks comprising slurred speech, left arm weakness and paresthesia. Carotid Doppler revealed total occlusion of the right internal carotid artery (ICA). Computed tomography angiography demonstrated occlusion of the proximal right ICA over a length of 1.5 cm. The ICA distal to the occlusion was entirely normal. In view of the normal distal ICA, a decision was made to proceed with surgical exploration and right carotid endarterectomy, on the basis that there must have been some flow through the lesion. Intra-operatively, there was an extensive plaque in the carotid bulb and proximal ICA causing 80-90% stenosis. Fresh thrombus completed the occlusion. An aberrant branch of the ICA was identified distal to the plaque, the backflow through which maintained patency of the distal ICA. A standard endarterectomy was performed. The patient recovered uneventfully, being discharged on the second post-operative day.

The influence of experience and specialisation on the reliability of a common clinical sign.

OBJECTIVES: To explore the influence of experience and specialisation on clinical judgement by comparing accuracy in diagnosing anaemia between a consultant general surgeon, a consultant ophthalmologist and their registrars. PATIENTS AND METHODS: Conjunctival inspection of 101 patients, subsequent correlation with haemoglobin concentration. MAIN OUTCOME MEASURES: Number of correct and incorrect diagnoses of anaemia. RESULTS: 54 patients were anaemic and 47 were not. Overall accuracy in diagnosing anaemia ranged from 0.61-0.69, sensitivity 0.52-0.65 and specificity 0.62-0.83. Agreements between pairs of examiners were 0.68-0.81, with kappa values of 0.36-0.60 when adjusted for chance agreement. CONCLUSIONS: Neither experience nor specialisation significantly influenced our ability to diagnose anaemia, based on conjunctival inspection. Without critical analysis of clinical signs, we are unaware of their diagnostic limitations.

Selective endoscopy in management of ingested foreign bodies of the upper gastrointestinal tract: is it safe?

During a four-year period, 308 patients presented following ingestion of foreign bodies. Ingestion was accidental in 272 cases (88.3%) and deliberate in the remainder. Symptoms at presentation included dysphagia, odynophagia, nausea and vomiting, chest pain and pharyngeal discomfort. Sixty-eight patients were asymptomatic. A policy of expectant management and selective endoscopy was employed. Following initial assessment 202 patients (65.6%) were discharged without treatment, 30 (9.7%) of whom were later reviewed as outpatients and did not require admission. Forty-nine patients (16%) were admitted for treatment; 27 had oesophagoscopy, five bronchoscopy and two had foreign body extraction with direct laryngoscopy. In nine patients who were endoscoped, no foreign body was identified. Twenty-seven others were referred to the otorhinolaryngology service in another hospital. There were no deaths in the group and morbidity was 1.2%. We conclude that a policy of selective endoscopy is safe and effective in the management of patients following ingestion of foreign bodies.

Deliberate ingestion of foreign bodies by institutionalised psychiatric hospital patients and prison inmates.

Deliberate and recurrent foreign body ingestion is a common problem among institutionalised patients. We review our experience with 36 cases of deliberate foreign body ingestion by prisoners or psychiatric patients, thirty of whom were institutionalised at the time of ingestion. Symptoms were frequently severe in the prison inmate group but, in contrast, psychiatric patients presented with few, if any, symptoms. A majority of objects pass spontaneously or remain in situ without complication. Twenty-four patients were discharged following initial evaluation and without specific treatment. Eight of these were reviewed electively and discharged within one week. Twelve patients were admitted for observation, seven of whom were discharged within 48 hrs. Upper gastrointestinal endoscopy was performed in four patients and an intragastric foreign body identified in two cases. Laparotomy was performed in two cases for unresolving mechanical intestinal obstruction. Management should be conservative when possible, with surgery indicated only for complications.

Paget's disease of the breast in a man without underlying breast carcinoma.

A case of histologically confirmed Paget's disease of the breast in a 72 year old man, without underlying breast carcinoma, is reported. This report raises questions about the pathogenesis of this condition and suggests that Paget's disease is an independent, intraepidermal carcinoma rather than a direct extension of intraductal carcinoma of the breast to the nipple and areola.
