Comparative StudyEffects of somatostatin, octreotide and pitressin plus nitroglycerine on systemic and portal haemodynamics in the control of acute variceal bleeding.
To examine the haemodynamic effects of somatostatin (SS) and octreotide (OC) versus pitressin plus nitroglycerine (PN) in the control of variceal bleeding, 224 patients with acute oesophageal and gastric variceal haemorrhage were randomly divided into three groups and treated with SS, OC and PN; they also had their Doppler ultrasound parameters measured before, during and after treatment. The success rates of bleeding control in the SS (80.9%, 86.8% and 89.7%, p<0.001) and OC (75.3%, 80.8% and 84.9%, p<0.01) groups were significantly higher than in the PN group (51.8%, 59.0% and 65.1%) at 24, 48 and 72 hours respectively, and the average duration of SS (12.7 + 6.8 h) and OC (13.8 + 8.0 h) was significantly lower than that of PN (24.6 + 15.4 h, p<0.001). Side-effects of SS (7.4%) and OC (8.2%) were less than those of PN (41.0%, p<0.001 and p<0.01). ⋯ Heart rate and cardiac output decreased significantly in patients treated with SS and OC; mean arterial pressure was unchanged. However, heart rate and mean arterial pressure increased, and cardiac output decreased, with PN. Somatostatin and octreotide were more effective than pitressin plus nitroglycerine in patients with acute variceal haemorrhage, with fewer side-effects, and may decrease PVF and portal vein pressure through reduction of cardiac output and dilatation of the visceral blood vessels.

Review Case ReportsFractured lateral epicondyle with associated elbow dislocation.
We describe a case series involving a very unusual injury in children, i.e. a Milch 1 fracture of the lateral condyle with an associated dislocation of the elbow. This fracture configuration is normally stable as the intact capitellotrochlear groove serves as a lateral buttress for the coronoid-olecranon ridge of the ulna. ⋯ These injuries usually present as a clinical dislocation and if the elbow is manipulated before radiographic imaging, the fracture line can be difficult to see on the post-reduction films. We recommend that all patients with a dislocated elbow should have elbow stability assessed under general anaesthesia, because a missed lateral condylar injury can lead to abnormalities in carrying angle, epiphyseolysis or an unstable elbow.

Management of chronic osteomyelitis in a developing country using ceftriaxone-PMMA beads: an initial study.
Chronic osteomyelitis is a debilitating disease that is fairly common in developing countries. Various operative techniques have been adopted in the management of this disease but there have been few reports of their use in Africa. In this report, we present our experience of the use of a modified two-staged Belfast operation in patients with chronic osteomyelitis in Ibadan, Nigeria. ⋯ There was recurrence of infection in three patients (8.6%) who had a suction drain inserted at the first stage and in six patients (17.1%) who had no suction drain at the first stage. The locally produced ceftriaxone-PMMA beads were found to be as efficient as the commercially available gentamicin beads in eluting antibiotics locally, thereby eliminating the residual infection in the bone cavities after the first stage. Another important outcome was a fourfold saving in cost in choosing to use ceftriaxone-PMMA beads rather than gentamicin beads.

Randomized Controlled Trial Multicenter Study Clinical TrialMultidose flurbiprofen 8.75 mg lozenges in the treatment of sore throat: a randomised, double-blind, placebo-controlled study in UK general practice centres.
The flurbiprofen 8.75 mg lozenge is a novel formulation that combines a demulcent effect with the analgesic activity of a non-steroidal anti-inflammatory drug. Previous controlled clinical studies have demonstrated the single- and multi-dose efficacy of these lozenges over placebo. ⋯ Additionally, significant benefit over placebo was demonstrated where concomitant antibiotic use was introduced, indicating that flurbiprofen 8.75 mg lozenges can be co-administered when antibiotic therapy is appropriate. No significant safety issues were identified.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of non-invasive ventilation and standard medical therapy in acute hypercapnic respiratory failure: a randomised controlled study at a tertiary health centre in SE Turkey.
This study was designed in a tertiary health centre in south-eastern Turkey to compare the effectiveness of non-invasive ventilation (NIV) plus standard medical therapy (ST) to ST alone, in acute hypercapnic respiratory failure (AHRF) due to chronic obstructive pulmonary disease (COPD) exacerbation. Thirty-four consecutive patients were randomly assigned to receive either NIV plus ST or ST alone. NIV was applied with a simple non-invasive ventilator through a full face mask in the general ward. ⋯ PaO2 (p<0.05) showed significant improvement only in the first hour of ST. The intubation rate and duration of hospitalisation in the NIV group were significantly shorter than those in the ST group (p<0.05). We conclude that NIV provides adjunctive therapeutic benefits compared with ST alone, and should be the choice of first step treatment in the AHRF due to COPD exacerbation in the appropriate setting and in selected patients.
