METHOD: A case series.
RESULTS: We present a case series of juvenile myasthenia gravis in a tertiary centre in Malaysia. Two of the three cases consist of a pair of twins who presented with ptosis of bilateral eyes; the first twin presented 4 months later than the second twin. These two cases were positive for anti-acetylcholine receptor antibodies and had generalized myasthenia gravis, whereas the other case was negative for receptor antibodies and was purely ocular myasthenia gravis.
CONCLUSION: Juvenile myasthenia gravis is relatively rare in toddlers. Early diagnosis and commencement of treatment is important to slow the progression of the disease and avoiding life-threatening events.
METHOD: We reviewed the medical records of 9550 women (9665 infants including 111 twins and two triplets) admitted to the labour wards of nine hospitals in four South East Asian countries during 2005. For women who gave birth before 34 weeks gestation we collected information on women's demographic and pregnancy background, the type, dose and use of corticosteroids, and key birth and infant outcomes.
RESULTS: Administration of antenatal corticosteroids to women who gave birth before 34 weeks gestation varied widely between countries (9% to 73%) and also between hospitals within countries (0% to 86%). Antenatal corticosteroids were most commonly given when women were between 28 and 34 weeks gestation (80%). Overall 6% of women received repeat doses of corticosteroids. Dexamethasone was the only type of antenatal corticosteroid used. Women receiving antenatal corticosteroids compared with those not given antenatal corticosteroids were less likely to have had a previous pregnancy and to be booked for birth at the hospital and almost three times as likely to have a current multiple pregnancy. Exposed women were less likely to be induced and almost twice as likely to have a caesarean section, a primary postpartum haemorrhage and postpartum pyrexia. Infants exposed to antenatal corticosteroids compared with infants not exposed were less likely to die. Live born exposed infants were less likely to have Apgar scores of < 7 at five minutes and less likely to have any lung disease.
CONCLUSION: In this survey the use of antenatal corticosteroids prior to preterm birth varied between countries and hospitals. Evaluation of the enablers and barriers to the uptake of this effective antenatal intervention at individual hospitals is needed.
OBJECTIVES: The objective of this review has been to evaluate the clinical effectiveness of available combined treatments modalities in the treatment of neovascular AMD.
DATA SOURCES: Central and Medline were searched for original research studies (Phase I, II, III), abstracts, and review articles concerning combination therapies for the control of neovascular AMD. We included randomized controlled trials (RCTs).
RESULTS: The results of therapeutic trials focused on the actual options in the management of neovascular AMD are discussed. Intravitreal treatment with substances targeting all isotypes of vascular endothelial growth factor (VEGF) results in a significant increase in visual acuity in patients with neovascular AMD. The combination with occlusive therapies like verteporfin photodynamic therapy (V-PDT) potentially offers a reduction of re-treatment frequency rate and long-term maintenance of the benefit reached. Despite the promise from combining anti-VEGF therapies with V-PDT, other combinations to improve outcomes with V-PDT deserve attention. Corticosteroids demonstrated an antiangiogenic effect and targeted the extravascular components of CNV, such as inflammatory cells and fibrocytes. Nevertheless, the study on the clinical application of corticosteroids will require a better understanding of the potential complications. Further developments interacting with various steps in the angiogenic cascade are under clinical or preclinical evaluation and may soon become available. In AMD the goal of a combination regimen is to address the therapy toward neovascular, inflammatory, and proliferative components of the disease.
CONCLUSIONS: Combined treatments strategies are an obvious step providing disease control when it is not achieved with a single therapeutic approach. One risk of using a single therapy to control AMD is a rebound induced by compensatory stimulation of other pathogenetic pathways. Combination therapy is a logical approach to address mechanisms of disease progression that appear to be self-sustaining once initiated.
PATIENTS AND METHODS: In total, 100 eyes from 50 patients on long-term intranasal steroids (>2 y) for allergic rhinitis and 90 eyes from 45 controls were included in this study. Patients on other forms of steroids and risk factors for glaucoma were excluded. IOP was measured and nonmydriatic stereoscopic optic disc photos were taken for each eye. The vertical cup-to-disc ratio and the status of the optic disc were evaluated.
RESULTS: The mean IOP for intranasal steroids group was significantly higher (15.24±2.31 mm Hg) compared to the control group (13.91±1.86 mm Hg; P=0.000). However, there were no significant differences in the vertical cup-to-disc ratio and the status of glaucomatous optic disc changes between the groups.
CONCLUSIONS: Prolonged use of intranasal steroids cause statistical significant increase in IOP in patients with allergic rhinitis although no significant glaucomatous disc changes were seen. We suggest patients on long-term use of intranasal steroid have a yearly eye examination to be monitored for IOP elevation and those with additional risk factors for glaucoma is closely monitored for glaucoma.
