Spontaneous resolution of gallstone ileus followed by imaging: A case report and a literature review.

Gallstone ileus (GI) is a rare cause of acute abdomen in an emergency setting and a rare complication of cholelithiasis in the elderly, with a female prevalence. Radiologists play a key role in the diagnosis and management of this condition and, with a multimodal approach, diagnostic accuracy usually increases. Spontaneous resolution of GI has previously been reported for stones smaller than 2 cm.

Secondary Neurolymphomatosis of the Radial Nerve: A Diagnostic Challenge.

BACKGROUND Secondary neurolymphomatosis is a rare clinical condition that may be observed in patients with hematologic malignancies. Clinical findings can overlap with other conditions. Diagnosis can be obtained by magnetic resonance imaging (MRI) and imaging with positron emission tomography (PET) and confirmed by biopsy.

Five-Membered N-Heterocyclic Scaffolds as Novel Amino Bioisosteres at γ-Aminobutyric Acid (GABA) Type A Receptors and GABA Transporters.

Given the heterogeneity within the γ-aminobutyric acid (GABA) receptor and transporter families, a detailed insight into the pharmacology is still relatively sparse. To enable studies of the physiological roles governed by specific receptor and transporter subtypes, a series of GABA analogues comprising five-membered nitrogen- and sulfur-containing heterocycles as amine bioisosteres were synthesized and pharmacologically characterized at native and selected recombinant GABA receptors and GABA transporters. The dihydrothiazole and imidazoline analogues, 5-7, displayed moderate GAT activities and GABA receptor binding affinities in the mid-nanomolar range ( K, 90-450 nM).

Role of color Doppler ultrasound in the early diagnosis of a major complication after percutaneous renal biopsy: two case reports.

Percutaneous renal biopsy (PRB) is an important procedure in the diagnostic and prognostic evaluation of renal disorders. Despite the relative simplicity, it can be a possible cause of iatrogenic renovascular injury. We describe two cases of iatrogenic pseudoaneurysm, a major post-biopsy complication, in two pediatric patients with persistent micro- and macro-hematuria, promptly diagnosed using color Doppler ultrasound, confirmed with renal arteriography and treated with embolization.

Clinical signs and radiographic evidence of esophageal perforation after tetraplegia.

A diagnosis of esophageal perforation at some time after cervical spine surgery is difficult to establish since there exists no clinical picture specific to tetraplegic patients. We carried out a detailed retrospective study of revelatory clinical manifestations and conventional radiographic data in a series of 16 patients hospitalized at Hôpital Henry-Gabrielle (Lyon, France) for rehabilitation purposes between 1983 and 2010 and who presented this complication. The most frequent clinical picture associates cervical pain, fever and dysphagia.
