BACKGROUND AND OBJECTIVE To describe a novel technique using a guarded needle to drain suprachoroidal hemorrhage. PATIENTS AND METHODS A guarded needle is used to drain suprachoroidal hemorrhage under direct microscope visualization. A scleral buckling sleeve is used to create a guarded 26-gauge needle to avoid over-penetration of the needle beyond the suprachoroidal space. Active extrusion c...

Pain Physician Vol. 9, No. 3, 2006 To the Editor: We report a case of intravascular uptake of contrast during interlaminar cervical epidural steroid injection (ESI) despite absence of spontaneous blood backflow through the needle hub and negative aspiration for blood. A 67-year-old female patient with neck pain and radiation of pain into her right shoulder and upper arm was referred to our pain...

OBJECTIVE A crucial problem in the non-operative diagnosis of thyroid nodules is the significant amount of non-diagnostic biopsies. This is a challenge for practicing endocrinologists especially when the results of the repeated biopsies remain non-diagnostic. The lack of a concrete preoperative diagnosis may result in unnecessary thyroidectomies in patients. Alternatively, it may also lead to t...

In childhood the traditional diagnostic approach to thyroid nodules consists of clinical, laboratory, and imaging evaluations. A safe and accurate procedure is needed to promptly identify patients who require surgery. In regard to the usefulness of fine needle aspiration biopsy, the data in the literature concerning children and adolescents are scanty. The aim of this study was to evaluate and ...

In 78 consecutive patients, we performed fine-needle aspiration of the hip before revision surgery. At the revision operation biopsies were taken from the capsule and joint tissues. The aspirate and the homogenised soft-tissue specimens were cultured using a radiomefric technique. Fifteen hips proved to be infected and 63 sterile on culture of the tissues taken during revision surgery; 94% of t...

PURPOSE The purpose of this study was the clinical evaluation of ultrasound-guided biopsy in comparison with ultrasound-guided fine-needle aspiration biopsy of identical, non-palpable breast lesions. MATERIALS AND METHODS From August 1997 until July 1998, 73 ultrasound-guided biopsies were performed in 66 patients with non-palpable lesions of the breast. In 18 patients (age 33-77 years) with ...

OBJECTIVE To analyze the individual and combined diagnostic yield and clinical utility of transbronchial needle aspiration and transbronchial biopsy in the histologic diagnosis of sarcoidosis in stages I and II. PATIENTS AND METHODS We performed a prospective study enrolling all the patients admitted to our hospital between July 2001 and June 2006 with mediastinal lymph nodes of a diameter of...

The use of fine needle aspiration cytology detected papillary carcinoma in two patients with multinodular goitre measuring 0.7 cm and 0.9 cm in diameter, respectively. Like most of the cases from previous large series, the tumours progressed slowly as shown by absence of enlarged glands on surgical exploration and no clinical signs of metastasis after two and five years of follow up. This study...
