Cat-301 immunoreactivity in the lateral geniculate nucleus and visual cortex of the strabismic amblyopic cat

Purpose: It was investigated whether alterations in neuronal structure and function occasioned by strabismic amblyopia also may be reflected in alterations in the expression on Y type neurons of a Cat-301 antibody sensitive antigen in the lateral geniculate nucleus (LGN) and cortex of our cat model of strabismic amblyopia. Methods/Results: The percentage of positively labelled cells was reduced in LGN laminae that received input from the deviated eye in strabismic amblyopic cats compared with normal cats. In the strabismic cortex, the density of immunopositive neurons was significantly reduced compared with normal, the effect being most pronounced in layer IV Conclusions: Despite previous physiological recordings indicating a decrease in X-cell associated acuity in strabismic amblyopia, the present findings imply that the changes in the early visual experience occasioned by strabismus also produce specific molecular changes in theY neuronal class.     

Evacuation of hematomas using liposuction technology: Technique and literature review

Established nonexpanding hematomas can be successfully treated with minimal morbidity using standard liposucstion techniques at the bedside or in an outpatient setting under local anesthesia. The authors presents a series of eight patients and discuss current concepts of dealing with this common and distressing surgical complication.     

Image-guided aspiration of solitary occult breast 'cysts'.

During the 30-month period from March 1, 1988, through August 31, 1990, image-guided aspirations of 183 solitary occult breast masses, which were considered possible cysts, were performed. Indications for aspiration included (1) mass on mammography, either invisible on ultrasonography or with features atypical of a cyst, in 111 patients; (2) enlarging solitary mass on mammography with ultrasonic features suggesting a cyst in 45 patients; and (3) mammographic mass with features typical of a cyst in 27 patients, with confirmation requested by the referring physician. Of the group, 151 (83%) lesions were fluid-filled and 32 (17%) were solid. All aspirates had normal cytologic features. Of the 32 aspirates found to be solid, 19 were subsequently removed after wire localization and 13 were unchanged on mammography for a minimum of 6 months after aspiration. This is a simple and safe procedure, confirming the innocuous nature of an occult solitary breast cyst, and obviates the need for surgical biopsy.     

Trabeculodialysis for inflammatory glaucoma: a review of 25 cases.

We reviewed the results following trabeculodialysis in 25 eyes of 22 patients with secondary glaucoma due to chronic anterior uveitis. After 1 year, intraocular pressure (IOP) was uncontrolled (greater than 21 mm Hg) in 11 eyes (44%). Trabeculodialysis controlled IOP (less than 21 mm Hg) in 14 eyes (56%), with an average follow up of 52 months (range, 12 to 151 months). Sixteen eyes (64%) were aphakic, but did no worse than the phakic eyes. One eye developed a subchoroidal hemorrhage 3 days postoperatively which required drainage. No other serious complications were encountered. Trabeculodialysis is a safe procedure which can achieve pressure control in these difficult eyes.

Avoiding complications in arthroscopic subacromial space and instability surgery

Arthroscopic shoulder surgery has become a safe tool for evaluation and treatment of a wide range of shoulder problems with few complications. With ever-improving technology (and commitment to motor skill development among arthroscopists), we can expect to maintain this low rate despite increasing procedure complexity. Avoiding complications in arthroscopic shoulder surgery requires careful preoperative planning, judicious patient selection, a thorough understanding of arthroscopic anatomy, and facility with arthroscopic techniques.
