Aim: The aim of this study was to assess the role of labelled leukocyte scintigraphy in the diagnosis and monitorization of response to therapy of patients with active bronchiectasis. Material and methods: Twenty patients underwent 99mTechnetium hexamethylpropyleneamine oxime (99mTc-HMPAO) labelledwhite blood cell (WBC) scintigraphy. A second scintigraphywas performed in 13 patients at 10 day o...

Various non-invasive investigations were carried out in patients infected with HIV who had respiratory symptoms with and without pneumocystis pneumonia (with pneumonia, n = 13 (five smokers); without pneumonia, n = 22 (13 smokers]. These included chest radiography; lung function tests (forced expiratory volume in one second, forced vital capacity; transfer factor and coefficient for carbon mono...

Background Familial amyloid polyneuropathy (FAP) is a severe hereditary disease, due to production by the liver of a genetic variant transthyretin (TTR) resulting in tissue amyloid deposits. Cardiac involvement is of major prognostic value. Diphosphonate scintigraphy has been proposed as a diagnostic tool for TTR-related cardiac amyloidosis, but there is no consensus on the optimal radiopharmac...

BACKGROUND Skeletal uptake of 99mTc labelled methylene diphosphonate (99mTc-MDP) is used for producing images of pathological bone uptake due to its incorporation to the sites of active bone turnover. This study was done to validate bone turnover markers using total skeletal uptake (TSU) of 99mTc-MDP. METHODS 22 postmenopausal women (52-80 years) volunteered to participate. Scintigraphy was p...

The purpose of this study was to establish whether liposomes administered via the intravenous route promote granulocyte aggregation and pulmonary leukostasis. White cells (labelled with [111In]tropolanate) and positively and negatively charged liposomes (containing entrapped [99mTc]DTPA) were administered i.v. to rats. The blood clearance and tissue distribution of 111In label was not altered b...

BACKGROUND The permeability of the alveolar-capillary barrier to technetium-99m labelled diethylenetriamine pentaacetate (99mTc DTPA) is known to be greatly increased in smokers, but the underlying mechanism is poorly understood. Abnormal permeability of the alveolar epithelium as well as impaired surfactant function has been suggested. The purpose of this study was to examine transudation of u...

A 77 year old male with history of renal lithiasis leading to right nefrectomy and end stage renal disease (ESRD) secondary to possible vascular nephropathy and focal segmental glomerulosclerosis diagnosed in 2009, started ambulatory peritoneal dialysis (APD) due to clinical decline. Insufficient drainage of the peritoneal dialysis solution with progressive bilateral testicular edema (more seve...

We reviewed all patients with a clinically infected foot ulcer attending a specialised neuropathic foot clinic. Neuropathy was confirmed by the inability to feel a 5.07 Semmes-Weinstein hair, areflexia and impaired vibration sense, as measured by a biothesiometer. Of 40 patients who attended the clinic over a two-year period, six with ischaemic ulcers were excluded. The remaining 34 had plain r...

In BCRL (breast cancer-related lymphoedema), arm swelling is unevenly distributed and some regions are partly or entirely spared. In particular, the hand may or not be swollen, but when involved functional impairment can be substantial. We have found previously that, when the ipsilateral hand is spared of swelling (in a limb with swelling proximal to the hand), the local lymph drainage rate con...

The residue and extraction of technetium-labelled methylene diphosphonate (99mTc-MDP), a substance used in bone scanning, was examined in the canine tibia and found to be low. Examination of washout curves suggested that there were four compartments in cortical bone, a vascular, a perivascular, a bone fluid and a bone compartment. After an osteotomy in the canine tibia the residue of 99mTc-MDP ...
