Iron deficiency anaemia over the last decades - Osler's disease diagnosed by Doppler and contrast-enhanced ultrasound.

CASE REPORT: A 72-year-old woman with a 30-year history of iron deficiency anaemia was admitted for fatigue and increasing weakness. On physical examination, the patient appeared dyspneic and pallor. The tongue showed angiodysplasias. Laboratory analysis showed a microcytary anaemia with an iron deficiency. Firstly a routine ultrasound examination (iU22, Philips Medical Systems) was performed. A left accessory artery, a dilated common hepatic artery and ectatic tortuous intrahepatic liver arteries were found. A contrast-enhanced ultrasound (CEUS) detected two intrahepatic arteriosystemic shunts in the left liver lobe. Endoscopy revealed multiple angiodysplasias of the stomach and the duodenum, 4 isolated angiodysplasias in the colon and telangiectasias in the oropharyngeal region. The angiodysplasias were treated with argon plasma coagulation. Osler's disease was diagnosed based on the Curacao criteria. CONCLUSION: Transabdominal B-mode sonography in combination with colour Doppler, pulsed wave Doppler and contrast-enhanced ultrasound is a very important tool to detect hepatic vascular malformations. It is an excellent procedure for the screening of patients with an iron deficiency anaemia. For the first time, we have demonstrated CEUS as an additional approach in the diagnosis of liver involvement in patients with Osler's disease.

Biomechanical evaluation of two reconstruction techniques for posterolateral instability of the knee.

We evaluated two reconstruction techniques for a simulated posterolateral corner injury on ten pairs of cadaver knees. Specimens were mounted at 30° and 90° of knee flexion to record external rotation and varus movement. Instability was created by transversely sectioning the lateral collateral ligament at its midpoint and the popliteus tendon was released at the lateral femoral condyle. The left knee was randomly assigned for reconstruction using either a combined or fibula-based treatment with the right knee receiving the other. After sectioning, laxity increased in all the specimens. Each technique restored external rotatory and varus stability at both flexion angles to levels similar to the intact condition. For the fibula-based reconstruction method, varus laxity at 30° of knee flexion did not differ from the intact state, but was significantly less than after the combined method. Both the fibula-based and combined posterolateral reconstruction techniques are equally effective in restoring stability following the simulated injury.

[Ultrasonographic diagnosis of a biliary-digestive fistula with gallstone ileus]. / Sonographische Diagnose einer biliodigestiven Fistel mit Gallensteinileus.

HISTORY AND CLINICAL FINDINGS: A 72-year-old woman was admitted to the hospital with upper abdominal pain, nausea, vomiting, and obstipation. INVESTIGATIONS: Percutaneous ultrasound found aerobilia, a biliary-digestive fistula, and an ileus with gallstones within the small bowel. The findings were confirmed at computed tomography. TREATMENT AND COURSE: A gallstone ileus on the basis of a biliary-digestive fistula was diagnosed. The patient was treated by surgery and with antibiotics. CONCLUSION: This case report demonstrates that percutaneous ultrasonography should be used as the first imaging procedure in the diagnosis of acute abdominal pain. This procedure makes it possible to detect a gallstone ileus. It is important also to define various intestinal structures accurately.

Revision arthroscopic partial meniscectomy of the knee. A retrospective review.

The aim in this study was to find out if there were any revision operations in patients who underwent an arthroscopic partial meniscectomy and we attempted to identify the factor(s) that may be associated with the need for that revision. We reviewed 1,603 patients who underwent an arthroscopic partial meniscectomy, and 16 cases of revision were identified (rate 1%). Nine factors were analysed: age, sex, affected knee, affected meniscus, private or National Health Service (NHS) patient, symptoms prior to the most recent meniscectomy, type of tear, history of re-injury and the progression of Outerbridge changes to the articular surfaces. There was a significant risk for a revision meniscectomy in patients with horizontal/partial thickness tears compared to flap tears. No additional factor analysed was significantly associated with a revision procedure.
