Isolated conjugate gaze palsy after frontal lobe tumour surgery

Isolated conjugate gaze palsy following unilateral frontal lobe surgery is uncommon. When it does occur, usually it recovers within hours. We report a case of isolated conjugate gaze palsy which persisted for four weeks post-operatively before recovery commenced.

Cataract surgery induces retinal pro-inflammatory gene expression and protein secretion

To investigate the effect(s) of cataract surgery on the expression of pro-inflammatory genes and proteins in the retina using an experimental rodent model. An extracapsular lens extraction was performed in one eye of C57BL/6 mice (n=24); the contralateral unoperated eyes (n =24) as well as eyes from unoperated animals (n = 9) served as controls. The neurosensory retina and retinal pigment epithelium (RPE)/choroid were collected postoperatively. Expression of genes involved in the acute inflammatory/ injury response, including IL-1ß, fibroblast growth factor, transforming growth factor ß, chemokine CCL2, SDF-1, and complements C3, C4, and factor B (CFB), were examined by real-time PCR and, selectively, by immunohistochemistry. The expression of IL-1 ß and CCL2 genes was markedly upregulated (>0-fold, P >0.01) in the neurosensory retina 30 minutes postoperatively and maintained for the 2-week postoperative period of observation; IL-1 ß expression was also upregulated in RPE/choroid. The expression of complement C3 (>-fold) and CFB (>0-fold) genes in the neurosensory retina was also significantly upregulated (P

Pre-Operative Visits to Reduce Patient Anxiety: A Study

The aim of this study was to evaluate the effect of pre-operative visits by theatre nurses on pre- and post-operative levels of anxiety in two groups of general surgical patients, and to see if the outcome was reflected in the level of post-operative pain, nausea, mobility or length of hospitalisation. One group received pre-operative visits while the other group did not. Results of the study showed a significant decrease in anxiety 24 to 72 hours post-operatively for the visited group. A positive relationship between pre-operative anxiety levels and the level of pain, nausea and lack of independence experienced by both groups was also found. Length of hospitalisation was unaffected by the level of anxiety experienced in both groups. The author recommends that all surgical patients should receive a visit from theatre nurses before their operation.

Recurrent lower gastrointestinal bleeding secondary to cytomegalovirus-associated colonic ulcer in a non human immunodeficiency virus infected patient:Timely diagnosis and treatment averted surgery

Mr C, a 68-year-old Chinese male with diabetes mellitus, previous stroke and ischaemic cardiomyopathy on clopidogrel, presented with haematochezia. Colonoscopy showed a sigmoid ulcer, which was treated endoscopically. Histology of the biopsy from the ulcer revealed non-specific changes. However, he presented with recurrent bleeding from this non-healing sigmoid ulcer. A review of the histologic specimen revealed CMV intranuclear inclusion bodies. He was treated with intravenous ganciclovir, with no further hematochezia.
