An experience of ultrasound-guided hydrostatic reduction of intrussusception at a tertiary care centre.

BACKGROUND: Intussusception is an important and one of the most commonly encountered diagnoses of intestinal obstruction in the paediatric age group. Ultrasound-guided hydrostatic reduction is an effective, nonoperative treatment modality for this condition and is associated with a high success rate. In addition, it is simple and safe as the entire procedure is carried out with real-time ultrasound, without the hazard of radiation. The aim of this study was to evaluate the effi cacy and safety of ultrasound-guided hydrostatic reduction in the management of intussusceptions in the paediatric age group. METHOD: A case study was carried out on 89 patients diagnosed with intussusception using high-resolution ultrasonography over a period of two years, spanning February 2012 to January 2014. Ultrasound-guided hydrostatic reduction was performed in 78 of these patients, and 11 patients were excluded owing to clinical contraindications. Follow-up ultrasound was performed after 24 hours to rule out recurrence. RESULTS: The disease was most prevalent in the age group 6-24 months. The ileocolic type was the most common. Mean duration (hours) was 17.02 ± 20.81 for time to presentation. Complete therapeutic reduction was achieved in 70 of the 78 cases, with a success rate of 90%. Two recurrences occurred in the following 24 hours, which were successfully reduced on the second attempt. Complications and mortality did not occur secondary to the procedure. CONCLUSION: Our study found that ultrasound-guided hydrostatic reduction is a simple, safe and effective nonoperative treatment for intussusceptions in the paediatric age group, and should be the fi rst line of management in appropriate patients.

Trans-axillary first rib excision for thoracic outlet syndrome.

AIM: Thoracic outlet syndrome (TOS) is a clinical diagnosis treatable by excision of the first rib. This study was undertaken to assess the alleviation of symptoms following trans-axillary rib excision in patients with a diagnosis of TOS suggested by a positive Elevated Arm Stress Test and, by inference, to estimate the prevalence of the syndrome. METHOD: A retrospective review of trans-axillary first rib excision was performed. No referrals were accepted from outwith the catchment area of our hospital. Post-operative symptomatic improvement was accepted as a confirmation of correct pre-operative diagnosis. RESULTS: Over six years, 52 rib resections were performed in 46 patients, mean age (+/- S.D.) 38.8 (+/- 10.6) years. The indications for surgery were principally neurological symptoms (n = 42 excisions), arterial compromise (n = 5) and venous compromise (n = 5). Symptoms had been present for a mean of 15.8 months prior to surgery. The median follow-up after surgery was 33 months. 42 patients (48 resections) showed immediate improvement in symptoms following surgery, although symptoms recurred in three patients (4 resections) between 6 and 8 months post-operatively. In the final two years of this study, 20 resections resulting in symptomatic improvement were performed, suggesting a prevalence for TOS of at least 10 per 100,000 per year. CONCLUSIONS: Thoracic outlet decompression was performed more frequently in this series than many previous reports, suggesting that TOS may be under-diagnosed.

Course and characteristics of anaemia in patients with rheumatoid arthritis of recent onset.

OBJECTIVE: To describe the incidence, cause, and course of anaemia in rheumatoid arthritis (RA). METHODS: Medical records of 225 patients who received a diagnosis of RA between 1990 and 1992 were reviewed longitudinally for mention of anaemia. Anaemia was classified as anaemia of chronic disease if ferritin concentrations reflected adequate body iron stores. Among iron depleted anaemic patients, iron deficiency anaemia was identified using the response to iron supplementation. RESULTS: Anaemia developed in 64% of the patients, mostly within 18 months of follow up, but disappeared again in 54% of those patients. The prevalence of anaemia varied from 39% to 53% throughout follow up. Iron depletion was found in 38% of anaemic patients; 40% of them did not recover from their anaemia after iron supplementation and were classified as having anaemia of chronic disease. Anaemia of chronic disease thus caused 77% and iron deficiency anaemia 23% of observed anaemia. Recovery from anaemia occurred in 42% of the patients with anaemia of chronic disease and in 72% of iron depleted patients after iron supplementation. Anaemic patients, particularly those with anaemia of chronic disease, had a significantly greater number of the American College of Rheumatism criteria for RA, significantly more erosive joint damage, and significantly increased concentrations of serum rheumatoid factor than patients without anaemia. CONCLUSION: Anaemia appeared as a frequent and dynamic manifestation. Recovery and recurrence of anaemia was observed throughout follow up, leading to a longstanding and relatively high prevalence of the condition. Iron deficiency was diagnosed frequently and follow up revealed a considerable overlap with anaemia of chronic disease, making this the most important cause of anaemia in RA. Recovery from anaemia occurred more frequently in iron depleted anaemic patients than in those with anaemia of chronic disease. Anaemic patients, particularly those with anaemia of chronic disease, seemed to have a more serious course of their RA compared with non-anaemic patients.
