Characterization of pneumatic retinopexy failures and the pneumatic pump: a new complication of pneumatic retinopexy [Case Report]

Gorovoy, Ian R; Eller, Andrew W; Friberg, Thomas R; Coe, Rodney
BACKGROUND:We review a three-year series of cases with pneumatic retinopexy (PR), specifically evaluating failures and suggesting a new mechanism of failure. METHODS:One hundred and thirty-five consecutive patients who underwent PR for rhegmatogenous retinal detachments were included. The primary outcome measure was the characteristics of PR failures. Secondary outcome measures included preoperative clinical characteristics. RESULTS:Seventy-five percent of the patients had successful results with PR; 100% were ultimately reattached with additional surgery. All but 1 failure (97%) occurred within the first postoperative month and 85% occurred by postoperative Day 10. The most common cause of failure was a new detachment from a new break (23 of 35 failures). Risk factors for failure included presenting visual acuity worse than 20/60 (odds ratio [OR] = 1.89), male gender (OR = 1.52), age >60 years (OR = 1.32), >2 breaks (OR = 1.28), pseudophakia/aphakia (OR = 1.20), and detachments after trabeculectomy (OR = 2.43). Lattice degeneration, high myopia (>-6.00 diopters), left eye, detachment after cataract surgery or yttrium aluminum garnet capsulotomy had minimal influence on outcome (all OR < 1.10). CONCLUSION/CONCLUSIONS:Characterization of PR failures will improve patient selection. We have named a new complication secondary to a patient performing the steamroller maneuver five times the "pneumatic pump."

Repair of limbal dermoid with excision and placement of a circumlimbal pericardial graft [Case Report]

Lazzaro, Douglas R; Coe, Rodney
OBJECTIVES: To report the treatment of a limbal dermoid tumor with excision of the lesion combined with the placement of a processed pericardial graft. METHODS: A case report of a new approach to treat large limbal dermoids after excision of the lesion from the cornea and limbus. RESULTS: The surgical result was very reasonable from a cosmetic result, and the patient recovered quite well. CONCLUSIONS: The use of processed pericardium on the scleral side of the lesion has not been reported previously with limbal dermoid excision. Intraoperatively, the abnormal tissue blended with the sclera and excision of perilimbal tissue was necessary to obtain a clear margin. One might want to consider the method described here for the treatment of large limbal dermoid lesions when the pathology seems indistinct at the conjunctival-corneal border during surgery.

Microarray analyses of peripheral blood cells identifies unique gene expression signature in psoriatic arthritis

Batliwalla, Franak M; Li, Wentian; Ritchlin, Christopher T; Xiao, Xiangli; Brenner, Max; Laragione, Teresina; Shao, Tianmeng; Durham, Robert; Kemshetti, Sunil; Schwarz, Edward; Coe, Rodney; Kern, Marlena; Baechler, Emily C; Behrens, Timothy W; Gregersen, Peter K; Gulko, Percio S
Psoriatic arthritis (PsA) is a chronic and erosive form of arthritis of unknown cause. We aimed to characterize the PsA phenotype using gene expression profiling and comparing it with healthy control subjects and patients rheumatoid arthritis (RA). Peripheral blood cells (PBCs) of 19 patients with active PsA and 19 age- and sex-matched control subjects were used in the analyses of PsA, with blood samples collected in PaxGene tubes. A significant alteration in the pattern of expression of 313 genes was noted in the PBCs of PsA patients on Affymetrix U133A arrays: 257 genes were expressed at reduced levels in PsA, and 56 genes were expressed at increased levels, compared with controls. Downregulated genes tended to cluster to certain chromosomal regions, including those containing the psoriasis susceptibility loci PSORS1 and PSORS2. Among the genes with the most significantly reduced expression were those involved in downregulation or suppression of innate and acquired immune responses, such as SIGIRR, STAT3, SHP1, IKBKB, IL-11RA, and TCF7, suggesting inappropriate control that favors proin-flammatory responses. Several members of the MAPK signaling pathway and tumor suppressor genes showed reduced expression. Three proinflammatory genes--S100A8, S100A12, and thioredoxin--showed increased expression. Logistic regression and recursive partitioning analysis determined that one gene, nucleoporin 62 kDa, could correctly classify all controls and 94.7% of the PsA patients. Using a dataset of 48 RA samples for comparison, the combination of two genes, MAP3K3 followed by CACNA1S, was enough to correctly classify all RA and PsA patients. Thus, PBC gene expression profiling identified a gene expression signature that differentiated PsA from RA, and PsA from controls. Several novel genes were differentially expressed in PsA and may prove to be diagnostic biomarkers or serve as new targets for the development of therapies
