The first description of ultrasound-guided dorsal scapular nerve blockade using a single-shot local anesthetic technique for the diagnosis and treatment of neck pain is reported. A 38-year-old female patient presented with neck pain, and the history and clinical examination strongly suggested myofascial pain affecting the middle scalene muscle. The pain had been unresponsive to pharmacological therapy or physiotherapy. After identifying the dorsal scapular nerve (DSN) in the body of the middle scalene muscle, an ultrasound-guided nerve block was performed using a single injection of local anesthetic to alleviate the patient’s pain. It has been demonstrated that the dorsal scapular nerve can be identified in the neck and effectively blocked using ultrasound guidance. This technique has the potential to assist in the diagnosis and treatment of neck pain originating from the middle scalene muscle.展开更多

A 35-year-old female presented to the pain clinic with severe chronic cervicogenic headache impacting her sleep, work and activities of daily living. Conservative management had failed to adequately resolve her pain. Ultrasound-guided suboccipital hydrodissection of the greater occipital nerve was performed with the patient in the prone position. After skin sterilization, the linear ultrasound transducer was oriented in a transverse orientation at the level of the C2-C3 vertebrae. The needle was advanced from medial to lateral “in-plane” under direct ultrasound visualization, until the needle was positioned at the C2 lamina. After confirming the needle tip position, 10 ml of hydrodissection fluid was injected with good visualization of distribution of the solution. The patient described immediate and significant improvement in her symptoms. She reported a sustained decrease in pain scores when followed up in the pain clinic at six and twelve weeks respectively. To the best of our knowledge this is the first application of ultrasound-guided hydrodissection of the GON for cervicogenic headache. It offers a novel, safe and effective technique to aid in the diagnosis and treatment of a common pain condition.展开更多

Since routine laboratory testing, the prevalence of the disease has increased from 0.1% to 0.4% worldwide. The only curative treatment is parathyroidectomy. Nowadays, preoperative localization studies have become standard before surgical treatment, and the first stage imaging methods are cervical ultrasonography (US) and/or Sestamibi scintigraphy. Objectives: To describe the accuracy of US and Sestamibi for detection of hyperfunctioning parathyroid adenomas preoperatively in patients with confirmed pHPT from our medical institution. Results: This is a retrospective study from a prospectively kept database that included thirty-one patients with the confirmed diagnosis of pHPT clinically and biochemically. The average age was 57.8 years old. Preoperative US and surgery findings were compared with a sensitivity of 51%. Preoperative Sestamibi and surgery findings were compared resulting in a sensitivity of 71%. Both imaging methods combined, resulted in a sensitivity of 80%. Conclusion: In patients with pHPT, Sestamibi is an effective method for localizing parathyroid pathology preoperatively, but the false negative rate can be high. US tends to have a wider range explained by the operator-dependent factor. The combination of US and Sestamibi reduces the rate of false negatives, as reported in international literature. It is important to mention that these studies cannot be used as a confirmatory test for this disease. It should only be used as an adjunct to help plan the operation.展开更多
