Purpose:
This study evaluated the objective changes in the contralateral eye after unilateral cataract surgery.
Methods:
The study was designed as retrospective observational study. It included 44 patients who underwent unilateral cataract surgery. Collected data were uncorrected and corrected visual acuity, spherical equivalent, intraocular pressure, contrast sensitivity (CS), stereoacuity, and anterior segment optical coherence tomography parameters. Data were collected preoperatively, and 1 week and 1 month postoperatively for each eye.
Results:
Following unilateral cataract surgery, the pupil size of the fellow eye decreased from 3.46 mm to 3.17 mm (postoperative week 1, p = 0.003) and 3.08 mm (postoperative month 1, p < 0.001). Anterior chamber depth of the fellow eye increased significantly from 3.16 mm to 3.27 mm (postoperative week 1, p = 0.005) and 3.26 mm (postoperative month 1, p = 0.001). Uncorrected distance visual acuity (UDVA) of the fellow eye improved significantly at postoperative week 1 (p = 0.042) and postoperative month 1 (p = 0.044). Change of UDVA of the fellow eye at postoperative month 1 was significantly correlated with that of the treated eye (p = 0.039).
Conclusions
Anterior chamber structures changed and UDVA improved in the contralateral eye after unilateral cataract surgery in our cohort. Because fellow eyes were positively affected by monocular cataract surgery, it would be good information if planning for unilateral cataract surgery due to inevitable reasons.

OBJECTIVE: The purpose of this study was to analyze the relationship between fracture pattern and the development of acute radiculopathy after osteoporotic lumbar compression fracture. METHODS: This study included 59 patients who underwent bone cement augmentation for osteoporotic compression fracture below the L2 level, which can lead to radiculopathic radiating pain. The patients were divided into two groups according to the presence of radiculopathy (group A : back pain only; group B : back pain with newly developed radiating pain). We categorized compression fractures into three types by the position of the fracture line. The incidence of newly developed radiculopathy was examined retrospectively for each compression fracture type. RESULTS: The overall incidence of newly developed leg pain (group B) was 25%, and the frequency increased with descending spinal levels (L2 : 0%, L3 : 22%, L4 : 43%, and L5 : 63%). The back pain-only group (group A) had mostly superior-type fractures. On the other hand, the back pain with radiculopathy group (group B) had mostly inferior-type fractures. Most patients in group B showed significant relief of leg pain as well as back pain after bone cement augmentation. CONCLUSION: The incidence of a newly developed, radiating pain after osteoporotic compression fractures increased gradually from the L3 to L5 levels. Most of these fractures were of the inferior type, and the bone cement augmentation procedures seemed to be sufficient for relief of both back and radiating pain.

Intracranial calcifications are relatively common computed tomographic findings in the field of neurosurgery, and cysticercosis, tuberculosis, HIV, and cryptococcus are acquired intracranial infections typically associated with calcifications. However, intracranial calcification caused by a bacterial brain abscess is rare. Here, we present a rare case of intracranial calcification caused by a bacterial brain abscess, from which staphylococcus hominis was isolated. To the best of our knowledge, no previous report has been published on intracranial calcification caused by bacterial brain abscess after decompressive craniectomy for traumatic brain injury. In this article, the pathophysiological mechanism of this uncommon entity is discussed and relevant literature reviewed.

A Schmorl's node is defined as a simple endplate intravertebral herniation resulting from trauma or idiopathic causes. Although Schmorl's nodes have been considered clinically insignificant, they might indicate an active symptomatic process or cause serious complications. In this study, we report an interesting case of complete separation of a vertebral body caused by an untreated Schmorl's node accompanying severe osteoporosis. To our knowledge, this is the first clinical report in the published literature to evaluate the complete separation of a vertebral body associated with a Schmorl's node.

OBJECTIVES AND OMPORTANCE: The present study investigated the levels of basic fibroblast growth factor(bFGF) in the CSF of patients with moyamoya disease and its clinical significance. METHODS: The levels of bFGF in CSF, taken from 26 hemispheres of 14 moyamoya patients and 20 patients without vascular anomaly(control group), were measured by an enzyme-linked immunosorbent assay. We analyzed the correlation between the level of bFGF and the clinical factors such as age, onset pattern, development of neovascularization, and cerebral circulation. RESULTS: The CSF of moyamoya patients contained a high concentration of bFGF to a significant extent. The bFGF level was apparently elevated in the patients in whom neovascularization from indirect revascularization, such as modified encephalo-duro-arterio-synangiosis(EDAS) was well developed. A linear correlation between the values of bFGF and clinical progression was noted. CONCLUSIONS: The elevation of bFGF in moyamoya disease seems to be specific. Clinically, the bFGF level may be considered a useful indicator to predict the efficacy of indirect revascularization.
