Valsalva-Like Retinopathy Spontaneously Occurred after Ocular Massage

Purpose

The aim of this study is to describe a case of Valsalva-like retinopathy that occurred after ocular massage.

Case Presentation

A healthy 44-year-old Japanese female had massaged her eye with strong pressure several times. Subsequently, she noticed a loss in the left central vision. A left-eye fundus examination showed a dense preretinal hemorrhage located under the internal limiting membrane at the posterior pole and a mild vitreous hemorrhage. We performed a neodymium-doped yttrium-aluminium-garnet laser membranotomy to perforate the internal limiting membrane. Her best-corrected visual acuity improved from 0.01 to 1.0. No retinal vascular abnormalities in the macular area were found.

Conclusion

Ocular massage can cause Valsalva-like retinopathy.Key Words: Neodymium-doped yttrium-aluminium-garnet laser membranotomy, Ocular massage, Valsalva-like retinopathy     

Adjunctive Use of Nonsteroidal Anti-inflammatory Drugs for Schizophrenia: A Meta-analytic Investigation of Randomized Controlled Trials

Objective: To meta-analytically assess the efficacy and tolerability of nonsteroidal anti-inflammatory drugs (NSAIDs) vs placebo in schizophrenia. Method: Searching PubMed, PsycINFO, ISI Web of Science, and the US National Institute of Mental Health clinical trials registry from database inception to December 31, 2012, we conducted a systematic review/meta-analysis of randomized placebo-controlled studies assessing the efficacy of adjunctive NSAIDs. Primary outcome was the change in Positive and Negative Syndrome Scale (PANSS) total score. Secondary outcomes included change in PANSS positive and negative subscores, all-cause discontinuation, and tolerability outcomes. Random effects, pooled, standardized mean changes (Hedges’ g) and risk ratios were calculated. Results: Across 8 studies, including 3 unpublished reports (n = 774), the mean effect size for PANSS total score was −0.236 (95% CI: −0.484 to 0.012, P = .063, I² = 60.6%), showing only trend-level superiority for NSAIDs over placebo. The mean effect sizes for the PANSS positive and negative scores were −0.189 (95% CI: −0.373 to −0.005, P = .044) and −0.026 (95% CI: −0.169 to 0.117, P = .72), respectively. The relative risk for all-cause discontinuation was 1.13 (95% CI: 0.794 to 1.599, P = .503). Significant superiority of NSAIDs over placebo regarding PANSS total scores was moderated by aspirin treatment (N = 2, P = .017), inpatient status (N = 4, P = .029), first-episode status (N = 2, P = .048), and (in meta-regression analyses) lower PANSS negative subscores (N = 6, P = .026). Interpretation: These results indicate that adjunctive NSAIDs for schizophrenia may not benefit patients treated with first-line antipsychotics judged by PANSS total score change. NSAIDs may have benefits for positive symptoms, but the effect was minimal/small. However, due to a limited database, further controlled studies are needed, especially in first-episode patients.Key words: schizophrenia, inflammation, treatment resistance, augmentation, concomitant, nonsteroidal anti-inflammatory     

Differences in expression patterns of cathepsin C/dipeptidyl peptidase I in normal,pathological and aged mouse central nervous system

Cathepsin C (CC) (EC 3.4.14.1, dipeptidyl peptidase I) is a lysosomal cysteine protease that is required for the activation of several granule‐associated serine proteases in vivo. CC has been shown to be constitutively expressed in various tissues, but the enzyme is hardly detectable in central nervous system (CNS) tissues. In the present study, we investigated the regional and cellular distribution of CC in normal, aging and pathological mouse brains. Immunoblotting failed to detect CC protein in whole brain tissues of normal mice, as previously described. However, low proteolytic activity of CC was detected in a brain region‐dependent manner, and granular immunohistochemical signals were found in neuronal perikarya of particular brain regions, including the accessory olfactory bulb, the septum, CA2 of the hippocampus, a part of the cerebral cortex, the medial geniculate, and the inferior colliculus. In aged mice, the number of CC‐positive neurons increased to some extent. The protein level of CC and its proteolytic activity showed significant increases in particular brain regions of mouse models with pathological conditions – the thalamus in cathepsin D‐deficient mice, the hippocampus of ipsilateral brain hemispheres after hypoxic–ischemic brain injury, and peri‐damaged portions of brains after penetrating injury. In such pathological conditions, the majority of the cells that were strongly immunopositive for CC were activated microglia. These lines of evidence suggest that CC is involved in normal neuronal function in certain brain regions, and also participates in inflammatory processes accompanying pathogenesis in the CNS.     

A case of micronodular pneumocyte hyperplasia diagnosed through lung biopsy using thoracoscopy

We present a case of a 39-year-old woman with sporadic tuberous sclerosis (TSC), whose chest radiograph demonstrated bilateral diffuse nodular shadowing. A transbronchial lung biopsy specimen revealed the possibility of multiple atypical adenomatous hyperplasia (AAH), which had not been reported in TSC. Thoracoscopic lung biopsy was, therefore, performed. The specimens revealed the characteristic histological and immunohistochemical features of micronodular pneumocyte hyperplasia, which has been reported as an extremely rare pulmonary manifestation of TSC. In addition, no evidence of AAH or any other pulmonary involvements of TSC including lymphangioleiomyomatosis were detected in biopsy specimens obtained at thoracoscopy.
