Fetomaternal outcome in pregnancy with oligohydramnios

Background: Oligohydramnios has been correlated with increased risk of FGR, meconium aspiration, birth asphyxia, low APGAR scores and congenital anomalies. Early detection of oligohydramnios and its management may help in reduction of perinatal morbidity and mortality. The aim and objectives of the study was to study the effect of oligohydramnios on fetal outcome in form of FGR, fetal distress, altered APGAR scores, NICU admission and early neonatal morbidity and mortality and to study maternal morbidity in the form of operative delivery and induced labour.Methods: 100 patients in third trimester of pregnancy with oligohydramnios confirmed by ultrasound measurement of AFI were selected randomly after satisfying inclusion and exclusion criteria.Results: Incidence of oligohydramnios and operative intervention for the same was seen more in primipara (52%). Most common causes of oligohydramnios were idiopathic (52%) followed by PIH (25%). Operative morbidity was highest in PIH (60%). Most common indication of caesarean section was fetal distress due to cord compression or FGR. 7% patients had fetoplacental insufficiency on Doppler study.Conclusions: Oligohydramnios demands intensive fetal surveillance and proper antepartum and intrapartum care. Due to high rates of intrapartum complications, perinatal morbidity and mortality, rates of caesarean section are rising, but decision between vaginal delivery and caesarean section should be well balanced so that unnecessary operative morbidity is prevented without jeopardizing the fetal well-being

Efficacy of synthetic pyrethroid and propoxur aerosol in the control of German cockroaches (Dictyoptera: Blatellidae) in cookhouses

Background & objectives: A field trial was carried out in cookhouses in an urban area to evaluate the efficacy of synthetic pyrethroid (0.02% deltamethrin + 0.13% allethrin) and propoxur aerosols (2%) in the control of German cockroaches (Blatella germanica)

Efficacy of synthetic pyrethroid and propoxur aerosol in the control of German cockroaches (Dictyoptera: Blatellidae) in cookhouses

Background & objectives: A field trial was carried out in cookhouses in an urban area to evaluate theefficacy of synthetic pyrethroid (0.02% deltamethrin + 0.13% allethrin) and propoxur aerosols (2%) inthe control of German cockroaches (Blatella germanica).Methods: A total of six cookhouses were selected by simple random sampling method (two each forthe two insecticide treatments and two for control).Results: It was observed that 89.36–87.8 and 77.95–59.74% reductions were achieved with propoxurand synthetic pyrethroid treatment respectively by first week post-treatment. The reduction in propoxurtreated areas by eight weeks post-treatment was 82.98–76.13%, whereas the reduction in thesame time period in synthetic pyrethroid treated areas ranged from 14.36% to an increase in density bya phenomenal 157.86% in one of the treated sites.Interpretation & conclusion: The study reports the efficacy of propoxur aerosol (2%) treatment oversynthetic pyrethroid (0.02% deltamethrin + 0.13% allethrin) in the control of cockroach infestation incookhouses in urban area

Antiviral treatment for acute retinal necrosis:A systematic review and meta-analysis

Acute retinal necrosis is a progressive intraocular inflammatory syndrome characterized by diffuse necrotizing retinitis that can lead to a poor visual outcome, mainly from retinal detachment. The antiviral treatment approach for acute retinal necrosis varies as there are no established guidelines. We summarize the outcomes of acute retinal necrosis with available antiviral treatments. Electronic searches were conducted in PubMed/MEDLINE, EMBASE, Scopus, and Google Scholar for interventional and observational studies. Meta-analysis was performed to evaluate the pooled proportion of the predefined selected outcomes. This study was registered in PROSPERO (CRD42022320987). Thirty-four studies with a total of 963 participants and 1,090 eyes were included in the final analysis. The estimated varicella-zoster virus and herpes simplex virus polymerase chain reaction-positive cases were 63% (95% CI: 55–71%) and 35% (95% CI: 28–42%), respectively. The 3 main antiviral treatment approaches identified were oral antivirals alone, intravenous antivirals alone, and a combination of systemic (oral or intravenous) and intravitreal antivirals. The overall pooled estimated proportions of visual acuity improvement, recurrence, and retinal detachment were 37% (95% CI: 27–47%), 14% (95% CI: 8–21%), and 43% (95% CI: 38–50%), respectively. Patients treated with systemic and intravitreal antivirals showed a trend towards better visual outcomes than those treated with systemic antivirals (oral or intravenous) alone, even though this analysis was not statistically significant (test for subgroup differences P = 0.83).</p

Levothyroxine in Women with Thyroid Peroxidase Antibodies before Conception

BackgroundThyroid peroxidase antibodies are associated with an increased risk of miscarriage and preterm birth, even when thyroid function is normal. Small trials indicate that the use of levothyroxine could reduce the incidence of such adverse outcomes.MethodsWe conducted a double-blind, placebo-controlled trial to investigate whether levothyroxine treatment would increase live-birth rates among euthyroid women who had thyroid peroxidase antibodies and a history of miscarriage or infertility. A total of 19,585 women from 49 hospitals in the United Kingdom underwent testing for thyroid peroxidase antibodies and thyroid function. We randomly assigned 952 women to receive either 50 μg once daily of levothyroxine (476 women) or placebo (476 women) before conception through the end of pregnancy. The primary outcome was live birth after at least 34 weeks of gestation.ResultsThe follow-up rate for the primary outcome was 98.7% (940 of 952 women). A total of 266 of 470 women in the levothyroxine group (56.6%) and 274 of 470 women in the placebo group (58.3%) became pregnant. The live-birth rate was 37.4% (176 of 470 women) in the levothyroxine group and 37.9% (178 of 470 women) in the placebo group (relative risk, 0.97; 95% confidence interval [CI], 0.83 to 1.14, P=0.74; absolute difference, −0.4 percentage points; 95% CI, −6.6 to 5.8). There were no significant between-group differences in other pregnancy outcomes, including pregnancy loss or preterm birth, or in neonatal outcomes. Serious adverse events occurred in 5.9% of women in the levothyroxine group and 3.8% in the placebo group (P=0.14).ConclusionsThe use of levothyroxine in euthyroid women with thyroid peroxidase antibodies did not result in a higher rate of live births than placebo.
