Fetal complete atrioventricular block (CAVB) is usually autoimmune mediated. The risk of developing CAVB is 2% to 3% in anti-Ro/SS-A seropositive pregnancies and it increases 10 times after previous CAVB in siblings. Despite being a rare complication, CAVB carries a 20% mortality rate and substantial morbidity, as about 65% of newborns will eventually need life-long pacing. Once found, fetal CAVB is almost always irreversible, despite aggressive immunotherapy. This poor outcome prompted some research groups to address this situation. All groups followed anti-Ro/SS-A seropositive pregnancies on a weekly basis during the second trimester of pregnancy and tried to detect first degree atrioventricular block (AVB) using accurate echocardiographic tools, assuming they may characterize the initiation of the immune damage to the A-V conduction system, at which point the process might still be reversible. Some of the groups treated fetuses with first degree AVB with maternal oral fluorinated steroids. We summarized the results of all groups, including our group. We describe a case of a fetus that developed CAVB 6 days after normal sinus rhythm (NSR), who under aggressive dexamethasone therapy gradually reverted to NSR. This fetus had a previous sibling with CAVB. We assumed the immune damage to the conduction system in this small group of fetuses with a previous CAVB sibling may have occurred more quickly than usual. We therefore recommend a twice-weekly follow-up with these fetuses

Background: The evidence on the use of dexamethasone implants in the treatment of Behçet’s disease (BD)-related uveitis is limited to a few cases. 

Objectives: To evaluate the efficacy of dexamethasone implants on ocular functional, morphological, and clinical parameters in BD patients with severe refractory uveitis. 

Methods: Five eyes from five BD patients were enrolled. A single intravitreal dexamethasone injection was applied to each eye. Best corrected visual acuity (BCVA), central macular thickness (CMT) assessed with optical coherence tomography, retinal vasculitis assessed by fluorescein angiography, vitreous haze score (Nussenblatt scale), intraocular pressure (IOP), and lens status (LOCS III, Lens Opacities Classification System III) were recorded at baseline and at 1, 3, and 6 month follow-up visits.

Results: At baseline, all eyes showed marked macular edema and 4/5 had concomitant active retinal vasculitis. Mean BCVA was increased from baseline at each control visit with a mean improvement of 0.26 ± 0.18 lines at 6 months follow-up. Mean CMT decreased from baseline at each control visit with a mean improvement at 6 months follow-up of 198.80 ± 80.08 µm. At the end of the study, none of the eyes showed macular edema and the mean CMT was 276.80 ± 24.94 µm. Retinal vasculitis resolved in all eyes. One eye experienced an IOP spike during treatment that resolved spontaneously, and one eye developed a clinically significant lens opacity at 6 months follow-up. 

Conclusions: Treatment with a dexamethasone implant in BD-uveitis and inflammatory macular edema was safe and effective as an additional treatment combined with systemic immunomodulatory drugs.

Background: There is currently no standard salvage chemotherapy for the 40–50% of patients with non-Hodgkin’s lymphoma who fail first-line treatment.

Objectives: To review the experience of a major tertiary medical center with DVIP (dexamethasone, etoposide, ifosfamide and cisplatin) salvage therapy for primary refractory/relapsing NHL[1].

Methods: We reviewed the records of all patients with NHL who received DVIP salvage therapy during the period 1993 to 2005.

Results: We identified 37 adult patients (mean age 56.3 years): 29 with aggressive lymphoma and 8 with indolent lymphoma. Mean event-free survival was 13.5 months (range 0–82 months), mean time between diagnosis and DVIP treatment 18.5 months (range 2–101), and mean number of DVIP cycles 1.9. Four patients (11%) achieved a complete response and 9 (24%) a partial response (overall response 35%). Consolidation with stem cell transplantation was used in 14 patients with aggressive lymphoma and 4 with indolent lymphoma; 14 patients, all with aggressive lymphoma, responded (12 complete, 2 partial). Of the 10 patients who underwent SCT[2] despite no response to salvage DVIP, 6 achieved a complete response. Five year overall survival from diagnosis for the whole sample was 39.4 ± 8.7%, and 5 year post-DVIP overall survival 37.6 ± 8.0%. On multivariate analysis, SCT was the strongest predictor of survival (relative risk 0.73, P < 0.0001) followed by a high score on the International Prognostic Index (RR[3] 3.71, P = 0.032).

Conclusions: DVIP salvage therapy for NHL was associated with a low response rate of 35% but a 5 year post-DVIP survival rate of 37.6%. Patients who are refractory to salvage treatment with DVIP might still be salvaged with SCT.
