Protocol for management of pregnant patients requiring emergency minor oral surgical procedures: a prospective study in 52 patients.

Objectives: Dental or maxillofacial emergencies are uncommon during pregnancy, but if they occur, they are challenging to treat due to potential risks. The mother should not be denied necessary medical or dental care because of pregnancy. The aim of the study is to observe outcomes of pregnancy in patients requiring emergency minor oral surgical procedures during gestation and to determine the safety of the pregnant woman undergoing the procedure and the fetus. Materials and Methods: The study was conducted on 52 pregnant women requiring emergency oral surgical procedures. A standard treatment protocol for treatment of specific entities was followed. Close monitoring and observation were the primary goal of treatment. All patients were followed postoperatively until complete recovery from the surgical procedures and then until birth of the baby. A control group of 52 healthy pregnant patients who did not require oral surgical procedures was considered for statistical analysis. The measurements to calculate observation were fetal loss (spontaneous abortion), preterm birth, low-birth weight, or incidence of any congenital anomalies in the baby and its association with surgical procedures. Results: No fetal loss occurred in any of the cases. However, four patients experienced preterm birth and seven neonates exhibited low birth weights. No congenital abnormalities were discovered. In one instance, a patient who underwent surgery for a mandibular symphysis fracture under general anesthesia in the 31st week of pregnancy experienced labor pain on the fourth postoperative day, requiring an emergency Caesarean section. Conclusion: The results of our study demonstrate that, compared to the control group, minor emergency surgeries performed during pregnancy have no discernible negative effects on the fetus. These procedures can safely be performed by adhering to our described protocols.

Vitreous Seed Classification and Regression Patterns in Eyes With Retinoblastoma.

Purpose: This work subclassifies retinoblastoma vitreous seeds and evaluates the efficacy, regression patterns, and adverse effects of combination intravitreal melphalan and topotecan chemotherapy for resistant and recurrent vitreous seeds. Methods: A retrospective review of medical records was conducted of patients with retinoblastoma and resistant or recurrent vitreous seeds who were treated with intravitreal melphalan and topotecan injections from August 2014 to July 2018. Main outcome measures included regression pattern, time for regression, time for recurrence of seeds, treatment outcomes, and ocular toxicity. Results: Nineteen eyes received 138 intravitreal injections over 74 treatment sessions (mean, 7.26 injections per eye); vitreous seeds regressed in 18 eyes. Of cloud vitreous seeds, curvilinear (n = 2) and sphero-linear (n = 2) subtypes were observed. During regression, some sphere seeds showed an intermediary streak-like pattern and took longer to regress (mean, 11.13 ± 14.05 months and 11.67 ± 8.62 injections) than those without the intermediary streak-like pattern (mean, 3.55 ± 2.57 months and 4.2 ± 1.87 injections). Mean follow-up was 34.87 ± 21.09 months (median, 35 months; range, 11-96 months). Anterior segment toxicity was seen in 10 (53%) eyes and posterior segment toxicity in 5 (26%) eyes. Kaplan-Meier survival estimates for globe salvage at 2 years was 94% and 73% at 5 years. Kaplan-Meier survival for vitreous seed-free status was 94% at 2 years and 65% at 5 years. Conclusions: An expanded vitreous seed classification system that further subcategorizes hitherto unrecognized vitreous seed morphology is needed. An intermediate streaking process results in a prolonged regression time for sphere vitreous seeds.

PERIPHERAL EXUDATIVE HEMORRHAGIC CHORIORETINOPATHY-A NEW ADDITION TO THE SPECTRUM OF PACHYCHOROID DISEASE?

PURPOSE: To demonstrate choroidal vascular changes and report a novel choroidal thickness contour in eyes with peripheral exudative hemorrhagic chorioretinopathy (PEHCR). METHODS: Retrospective, observational, comparative case series. Fourteen eyes of nine patients with PEHCR and 14 eyes of 14 age-matched and sex-matched controls underwent swept-source optical coherence tomography. Choroidal thickness was measured from posterior edge of the retinal pigment epithelium-Bruch membrane to choroidoscleral interface at 11 points 1,000 µm apart. Large choroidal vessel thickness was also measured. RESULTS: In PEHCR group, the choroid was thinnest at 3 mm nasal to fovea (mean 95.3 ± 33.5 µm) and thickest at 7 mm temporal to fovea (mean 272.7 ± 80.2 µm), with gradual increase in choroidal thickness from nasal to temporal periphery. The choroid was thickest subfoveally (259.7 ± 63.8 µm) in the control group. The choroid was significantly thicker in temporal periphery in PEHCR eyes as compared to controls (P = 0.0002). The mean large choroidal vessel thickness was 202.4 ± 50.8 µm in the PEHCR group and 160.6 ± 40.5 µm in the control group (P = 0.0235). CONCLUSION: Peripheral exudative hemorrhagic chorioretinopathy eyes showed progressively increasing choroidal thickness toward the temporal periphery, compared with age-matched and sex-matched controls. This gave rise to a club-shaped choroidal contour compared with the bowl-shaped contour seen in control eyes. Thicker choroid and pachyvessels favor inclusion of PEHCR in the pachychoroid disease spectrum.

Intra-Arterial Chemotherapy for Retinoblastoma: Four-Year Results from Tertiary Center in India.

BACKGROUND: There are limited reports of intra-arterial chemotherapy (IAC) for retinoblastoma (RB) from developing world. OBJECTIVES: In this study, we report our 4-year experience of IAC for RB from India. METHODS: Retrospective, interventional case series. Primary outcome measures included tumor regression, vitreous seeds and subretinal seeds control, and globe salvage. Secondary outcome measures were best-corrected visual acuity and treatment complications. RESULTS: Fifteen eyes underwent 53 IAC procedures over mean 28.6 ± 13.8 months (range 10-51 months). IAC was employed as primary (n = 6) or secondary (n = 9) chemotherapy. Following IAC, complete regression of main tumor was seen in 7 eyes (47%) and partial regression in 3 (20%) eyes. Enucleation was done in 5(33%) eyes. Globe salvage rates were achieved in 1 eye (100%) in group B, 2 eyes (67%) in group C (n = 3), 6 eyes (67%) in group D (n = 9), and 1 eye (50%) in group E (n = 2). Following IAC, Kaplan-Meier survival curve showed 93% globe survival rate at 1 year, 76% at 2 years, and 66% at 3, and 4 years. CONCLUSION: IAC has enhanced globe salvage rates in eyes with RB. Multicenter studies with longer follow-up are necessary to better understand outcomes in the long term.

Incidence, outcomes, and risk factors for hemorrhagic complications in eyes with polypoidal choroidal vasculopathy following photodynamic therapy in Indian subjects.

PURPOSE: To evaluate the incidence, outcomes, and risk factors for hemorrhagic complications in eyes with polypoidal choroidal vasculopathy (PCV) following photodynamic therapy (PDT). METHODS: Medical records of 94 eyes of 86 consecutive patients with PCV who underwent PDT between January 2007 and December 2014 were retrospectively reviewed. The diagnosis of PCV was based on clinical features and indocyanine green angiography. Eyes were treated with PDT monotherapy or a combination of PDT plus anti-vascular endothelial growth factor. PDT was performed at (standard [SFPDT] or reduced fluence RFPDT). RESULTS: Ninety-four eyes had 119 PDT treatment sessions (mean: 1.3 sessions). Mean presenting vision was 0.46 ± 0.44 logarithm of the minimum angle of resolution (logMAR). Following PDT, ten eyes (11%) of nine patients had hemorrhagic complications such as subretinal hemorrhage (SRH; n = 5), subretinal pigment epithelium (RPE) hemorrhage (n = 1), breakthrough vitreous hemorrhage (BVH; n = 3), and SRH with sub-RPE hemorrhage and BVH (n = 1). Median interval to hemorrhage following PDT was 2 months. Age (P = 0.842), duration of symptoms (P = 0.352), number of laser spots (P = 0.219), and laser spot size (LSS) (P = 0.096) were not significantly associated with increased risk of hemorrhagic complications. Female gender was associated with reduced risk of hemorrhage (P = 0.045). SFPDT was significantly associated with increased risk of hemorrhage (P = 0.026). The probability of developing hemorrhagic complications in SFPDT group was 0.24 compared to 0.07 in RFPDT group (P = 0.039). Multivariate logistic regression analysis showed SFPDT as the only significant risk factor for hemorrhage following PDT (odds ratio 5.3, 95% confidence interval 1.1-24.8, P = 0.03). Mean final vision was 0.61 ± 0.53 logMAR at mean follow-up of 33 months (median = 22 months; range = 2-157 months). CONCLUSION: Age, LSS, number of laser spots, preexisting hemorrhages, or use of anticoagulants were not associated with increased risk of hemorrhagic complications. SFPDT was significantly associated with increased risk of hemorrhagic complications in such eyes.

Intra-arterial chemotherapy for retinoblastoma: Two-year results from tertiary eye-care center in India.

AIM: The aim of this study is to describe treatment outcomes and complications of selective intra-arterial chemotherapy (IAC) for intraocular retinoblastoma (RB). MATERIALS AND METHODS: A retrospective, interventional series of 10 eyes with RB which underwent IAC using melphalan (5 mg/7.5 mg) and topotecan (1 mg), or melphalan (5 mg/7.5 mg) alone. Treatment outcomes were evaluated in terms of tumor control, vitreous seeds (VS) and subretinal seeds (SRS) control, and globe salvage rates. RESULTS: Ten eyes of 10 patients underwent 38 IAC sessions (mean = 3.8; median = 4; range = 3-5 sessions). Following IAC, complete regression of main tumor was seen in 9 eyes (90%) and partial regression in 1 (10%). All four eyes with SRS showed complete regression (100%). Of 5 eyes with VS, 3 eyes (60%) showed complete regression, 1 eye (20%) showed relapse, while 1 eye (20%) showed no response. Globe salvage was achieved in 8 of 10 eyes (80%). Complications included transient ophthalmic artery narrowing (n = 2), branched retinal vein occlusion (n = 1), forehead skin pigmentation (n = 1), and vitreous hemorrhage (n = 2). There was no case of stroke, hemiplegia, metastasis, or death. Transient hematological changes included relative pancytopenia (n = 4), relative leukopenia (n = 5), and relative thrombocytopenia (n = 4). Mean follow-up was 26 months (median = 28, range = 13-36) from the initiation of first IAC. CONCLUSIONS: IAC is an effective therapy for globe preservation in eyes with intraocular RB, in the setting of a developing country like India. Larger studies with longer follow-up are required to validate these results.

Grandmothers' influence on child care.

OBJECTIVE: This paper compares child care-giving and child's nutritional status among rural families where grandmothers were present and those where grandmothers were absent. METHODS: From 27 villages in rural Vadodara, four were randomly selected and all the families (n=31) with children (3-24 months) where grandmothers were present (GMP) were compared with 39 families where grandmothers were absent (GMA). Semi structured questionnaires were used to assess beliefs-practices of mothers and grandmothers regarding breastfeeding and complementary feeding (BF-CF). Nutrient intake of the children and nutritional status were measured using standard procedures. RESULTS: Some deleterious practices were present in a similar proportion of both GMP and GMA groups: giving prelacteals, delaying initiation of BF, exclusive breastfeeding < 3 months and delaying initiation of CF. Favorable practices present in significantly more GMP were: active feeding and use of anganwadi services. Grandmother's help enabled mother to practice more care-giving behaviors. However, children in both the groups had low calorie intake CONCLUSION: Role of family members in childcare and the benefits of including them in interventions to improve child survival, health and nutrition status need to be further researched.
