History Of

A 25-year-old man was referred to the urology department after a subacute history of left back pain, burning micturition associated with pneumaturia and fecaluria. Ultrasonography was performed showing hydronephrosis, and plain film radiography demonstrated a long vertical left pelvic calculi. Uro-computed tomography (CT) combined with a water enema CT showed a 10 cm long calculus with the cranial extremity fistulating the sigmoidal wall. Surgical treatment included left nephroureterectomy and sigmoidectomy with a colorectal anastomosis. Postoperative course was uneventful.

This case report presents a lipofibromatous hamartoma of the median nerve in a 31-year-old man who presents local deformity and a sensory deficit in the nerve territory. The tumor was evaluated with magnetic resonance, computed tomography, and plain film radiography, studying the pathognomonic findings of this tumor. The patient did not want surgical treatment because of prior surgical sequelae. A prior surgical biopsy was reported as a peripheral nerve with normal axonal fascicles surrounded by abundant fibroadipose tissue. This tumor has a low incidence with less than 180 cases reported in the literature.

Plain Film Radiography

Cone beam computed tomography (CBCT) can be a useful adjunct to conventional plain film radiography, but its use must be carefully justified as the radiation dose is generally higher. Factors affecting the dose include the field of view (FOV) size, the exposure factors, the angle of rotation and voxel size. Once justified, the exposure should be fully optimised to ensure the dose to the patient is kept as low as possible while ensuring there is no reduction in the diagnostic yield. The European Commission (EC) and the Faculty of General Dental Practice (FGDP)(UK) have published selection criteria on the use of CBCT in dentistry. This article provides an overview of CBCT and summarises the latest guidance on selection criteria relevant to the general dental practitioner.

Objective This study aims to define a reliable protocol for radiographic identification of placement and tip foldover of newly designed precurved and straight electrodes. Study Design Prospective imaging study. Setting Academic institution. Methods Three models of cochlear implants (Cochlear, MED-EL, and Advanced Bionics) were inserted into fresh cadaveric specimens (n = 2) in 3 configurations (normal positioning in the scala tympani, intracochlear tip foldover, and placement into the vestibular system) for a total of 9 implant scenarios. Specimens were imaged with plain radiography in Stenvers projection, as well as by high-resolution computed tomography. Results Electrode placement and presence or absence of electrode tip foldover were easily identified in all 9 scenarios on plain radiography based on the described technique. Each was confirmed with high-resolution computed tomography. Plain film temporal bone images of new electrode designs with proper and improper placement are provided for reference. Conclusion A defined protocol for intraoperative plain film radiography allowed for reliable imaging of 3 newly designed cochlear implant electrodes and immediate identification of extracochlear placement and tip foldover. Findings may be used for intraoperative confirmation of electrode array placement.

The author presents a patient who developed a subacute subdural hematoma approximately 2 weeks after normal delivery with history of postnatal convulsion and lateralizing neurological symptoms. On day 12, she started to feel a nonpostural and severe throbbing headache with motor aphasia and right hemiparesis power grade 4, she was referred to our department. Left subacute subdural hematoma was confirmed by a computed tomography scan. Physical examination revealed only mild right hemiparesis. Left burr hole trepanation was performed and this was followed by uneventful postoperative course, and it completely recovered after 4 weeks. Chronic subdural hematoma should be considered when postpartum patients who have history of ecclampsia with mild to severe, persistent, and non-postural headache.Nepal Journal of Neuroscience.

Abstract We report a case of a 58-year-old female with Stanford type A aortic dissection sparring the donor aorta 2 years after heart transplantation. Lumbar spine magnetic resonance examination for low back pain discovered the aortic dissection which was confirmed by following computed tomography angiography. The patient received surgical treatment including total arc replacement and thoracic aortic endovascular repair and recovered well.

Extent Of Disease

Fifty patients who underwent intranasal sphenoethmoidectomy at the St Louis University Medical Center between July 1977 and April 1980 have been evaluated with respect to preoperative extent of disease and medication requirement as well as postoperative course and reduction in medication requirements, if any. These patients were followed jointly by the Departments of Allergy and Otolaryngology. Most of these patients were not allergic, and over half had intrinsic asthma. Fifteen of the 50 patients, all asthmatic, gave a history of aspirin sensitivity. Many had had previous nasal surgical treatment for polyps. Patients on large corticosteroid dosages had long-lasting reductions or elimination of their corticosteroid requirements in most cases. Similarly, most patients had long-lasting nasal airway improvement and reduction or elimination of recurring sinusitis. Antibiotics and antihistamine-decongestant preparations were sharply diminished in these patients. Although aspirin sensitivity was associated with some of the more severe asthmatic patients, it appeared not to be a factor in the responses to surgical treatment.

Bacillus Calmette-Guérin (BCG) is an attenuated strain of Mycobacterium bovis that has been effectively used in the treatment of non-muscle invasive bladder carcinoma. The complications of this treatment are uncommon, and the causes of dissemination are still discussed. We report a case of disseminated tuberculosis in a 66-year-old smoking man without a history of pulmonary diseases, who underwent immunotherapy with BCG after the initial surgical treatment of bladder cancer. After the last BCG instillation, he developed a fever. The diagnosis of sepsis was not confirmed, and miliary pulmonary tuberculosis was suspected. The diagnosis was confirmed by clinical manifestation, computed tomography of the lungs, and histological examination.
