#1
J A Sutton, R P Clauss
During 15 years, 23 clinical reports and 6 studies have demonstrated associations between sub-sedative doses of zolpidem and recoveries from brain damage due to strokes, trauma and hypoxia. Clinical findings include unexpected awakenings from vegetative states and regressions of stroke symptoms after dosing that disappear during elimination and reappear on repeat dosing. Initially single-photon emission computed tomography scans showed improved perfusion within, around and distant from infarctions. Then positron emission tomography scans and electroencephalography detected renewed metabolic and neuronal activity...

An area of increased activity in segment IV of liver (quadrate lobe) on (99m)Tc-sulfur colloid (TSC) scans has been well documented in patients with superior vena cava obstruction. Similarly intense enhancement of the quadrate lobe in the arterial phase may be seen on computed tomography in patients of superior vena cava syndrome. We present this imaging finding in a case of malignant thymoma causing superior vena cava syndrome and discuss the physiological cause and importance of this sign.

Systemic lupus erythematosus (SLE) is a multisystem disorder which can affect the gastrointestinal (GI) system. Although GI symptoms can manifest in 50% of patients with SLE, these have barely been reviewed due to difficulty in identifying different causes. This study aims to clarify clinical characteristics, diagnosis and treatment of the four major SLE-related GI system complications: protein-losing enteropathy (PLE), intestinal pseudo-obstruction (IPO), hepatic involvement and pancreatitis. It is a systematic review using MEDLINE and EMBASE databases and the major search terms were SLE, PLE, IPO, hepatitis and pancreatitis...

Multiple possibilities for the coordination of fac-[Re(CO)3(H2O)3](+) to a protein have been determined and include binding to Asp, Glu, Arg and His amino-acid residues as well as to the C-terminal carboxylate in the vicinity of Leu and Pro. The large number of rhenium metal complex binding sites that have been identified on specific residues thereby allow increased target identification for the design of future radiopharmaceuticals. The core experimental concept involved the use of state-of-art tuneable synchrotron radiation at the Diamond Light Source to optimize the rhenium anomalous dispersion signal to a large value (f'' of 12...

PURPOSE: Sentinel lymph node biopsy (SLNB) can be used for nodal staging in early cervical cancer. For this purpose, the tracers most commonly used are radiotracers based on technetium. For the last decade, indocyanine green (ICG) has been used as a tracer for SLNB in other malignancies with excellent results and, more recently, a combination of ICG and a radiotracer has been shown to have the advantages of both tracers. The aim of this study was to evaluate the role of ICG-(99m)Tc-nanocolloid in SLN detection in patients with cervical cancer...

BACKGROUND: Adenoid cystic carcinoma (ACC) of the larynx and trachea is very rare. CASE: A 45-year-old man with ACC of the larynx presenting as a thyroid mass is reported in this study. Physical examination revealed a large solid thyroid nodule in the left lobe without any lymphadenopathy. A technetium thyroid scan showed multinodular goiter with cold nodules in the left lobe, isthmus, and functioning nodules in the right lobe. A large thyroid mass originating from the left side of the larynx, mostly the left vocal cord and the infraglottic part, was seen using enhanced magnetic resonance imaging after rupture of the thyroid cartilage on the left side...

Preoperative evaluation of liver functional reserve is important in hepatobiliary surgery. Although the indocyanine green retention rate at 15 minutes (ICG-R15) is the gold standard for this purpose, a new method without technical complexity would be preferable. We assessed the usefulness of the previously established index of convexity (IOC). In total, 159 consecutive patients who underwent both technetium-99m-galactosyl human serum albumin ((99m)Tc-GSA) scintigraphy and the ICG-R15 were included. Correlation coefficients between indices from (99m)Tc-GSA scintigraphy and blood examinations including ICG-R15 were evaluated, and a conversion formula from the IOC to the ICG-R15 was established...

We report here a rare case of primary hyperparathyroidism that was associated with an ectopic parathyroid adenoma located in the mediastinum. A 66-year-old woman suffering from primary hyperparathyroidism had been followed-up on an outpatient basis for over 10 years. She suffered from persistent urolithiasis and osteopenia due to hypercalcemia. After technetium-99-sestamibi (99mTc-MIBI) scintigraphy revealed an ectopic adenoma in the superior mediastinum, thoracoscopic resection of the tumor was performed. Subsequently, her serum parathyroid hormone (PTH) level decreased dramatically and her serum calcium concentration was restored to normal...

BACKGROUND: There is a long history of nuclear medicine developments in orthopaedics beginning in the early 20(th) century. Technetium-99m ((99m)Tc) has a short half-life of six hours, emits 140 keV gamma rays and is the most widely used isotope, imaged with the Anger (gamma) camera. Gamma image quality and test sensitivity in painful prosthetic joints can be improved with single photon emission computed tomography (SPECT) and SPECT/CT. Positron Emission Tomography-Computed Tomography (PET-CT) with Sodium Fluoride ((18)F-NaF) and (18)Fluorine-fluorodeoxyglucose ((18)F-FDG) PET have promising and limited roles respectively in the investigation of painful prosthetic joints...
