Clinical patterns of congenital ocular anomalies in the pediatric age group (0 to 5 years) and its association with various demographic parameters

Purpose:Congenital ocular anomalies are rare but important cause of childhood blindness. This study aimed to observe the clinical patterns of congenital ocular anomalies in the pediatric age group (0 to 5 years) and its association with various demographic parameters.Methods:Hospital-based cross-sectional study done on all pediatric patients in the 0-to-5-year age group presenting with congenital ocular anomalies to the Ophthalmology department of a tertiary care hospital in Eastern India between October 2018 and October 2020. Thorough clinical history was obtained, and comprehensive ocular examination was done in each case.Results:A total of 5686 patients in the 0 to 5 years age group attended the eye OPD during the study period. Congenital ocular anomalies were seen in 140 patients. The prevalence of ocular anomalies was 2.46%. Average age of patients was 3.32 ± 1.42 years. There were 74 (52.9%) males and 66 (47.1%) females. Unilateral and bilateral involvement was seen in 100 (71.45%) and 40 (28.6%) cases, respectively. Antenatal period was uneventful in 92.14% cases. Decreased vision was the most common presentation (40%). Congenital nasolacrimal duct obstruction was the most common anomaly seen in 29 (20.71%) cases followed by congenital cataract in 21 (15%) cases.Conclusion:Few of the congenital ocular anomalies can be prevented by increasing community awareness. Findings of the study can act as a reference guide for clinicians and health professionals for counseling and health planning.     

In vitro antiprotozoal activity of some xanthones isolated from the roots of Andrographis paniculata

Four xanthones isolated from the roots of Andrographis paniculata were tested in vitro for antiprotozoal activity against Trypanosoma brucei brucei, Trypanosoma cruzi and Leishmania infantum. Compound TDR13011 (1,2-dihydroxy-6,8-dimethoxy-xanthone) showed good activity against T. b. brucei and L. infantum with a 50% inhibitory concentration (IC50) of 4.6 microg/ml and 8 microg/ml respectively. Xanthones from the roots of Andrographis paniculata exhibited promising anti-protozoal activity and these compounds could be chemically modified to obtain a more potent product.     

Mutational Analysis of the Rhodopsin Gene in Sector Retinitis Pigmentosa

Background: To determine the role of rhodopsin (RHO) gene mutations in patients with sector retinitis pigmentosa (RP) from Northern Ireland.

Design: A case series of sector RP in a tertiary ocular genetics clinic.

Participants: Four patients with sector RP were recruited from the Royal Victoria Hospital (Belfast, Northern Ireland) and Altnagelvin Hospital (Londonderry, Northern Ireland) following informed consent.

Methods: The diagnosis of sector RP was based on clinical examination, International Society for Clinical Electrophysiology of Vision (ISCEV) standard electrophysiology, and visual field analysis. DNA was extracted from peripheral blood leucocytes and the coding regions and adjacent flanking intronic sequences of the RHO gene were polymerase chain reaction (PCR) amplified and cycle sequenced.

Main Outcome Measure: Rhodopsin mutational status.

Results: A heterozygous missense mutation in RHO (c.173C?>?T) resulting in a non-conservative substitution of threonine to methionine (p. Thr58Met) was identified in one patient and was absent from 360 control individuals. This non-conservative substitution (p.Thr58Met) replaces a highly evolutionary conserved polar hydrophilic threonine residue with a non-polar hydrophobic methionine residue at position 58 near the cytoplasmic border of helix A of RHO.

Conclusions: The study identified a RHO gene mutation (p.Thr58Met) not previously reported in RP in a patient with sector RP. These findings outline the phenotypic variability associated with RHO mutations. It has been proposed that the regional effects of RHO mutations are likely to result from interplay between mutant alleles and other genetic, epigenetic and environmental factors.     

Does Scalp Cooling Have the Same Efficacy in Black Patients Receiving Chemotherapy for Breast Cancer?

Lessons Learned

• Despite U.S. Food and Drug Administration approval to reduce alopecia, data on efficacy of scalp cooling in Black patients with cancer are limited by lack of minority representation in prior clinical trials.
• Scalp cooling devices may have less efficacy in Black patients; additional studies are required to explore the possible causes for this, including hair texture and cap design.

BackgroundThe Paxman scalp cooling (SC) device is U.S. Food and Drug Administration (FDA)‐approved for prevention of chemotherapy‐induced alopecia. Studies report 50%–80% success rates and high patient satisfaction, yet there have been no studies of SC in Black patients. We conducted a phase II feasibility study of Paxman SC with a planned enrollment of 30 Black patients receiving chemotherapy for stage I–III breast cancer.MethodsBlack patients who planned to receive at least four cycles of chemotherapy with non‐anthracycline (NAC) or anthracycline (AC) regimens were eligible. Alopecia was assessed by trained oncology providers using the modified Dean scale (MDS) prior to each chemotherapy session. Distress related to alopecia was measured by the Chemotherapy Alopecia Distress Scale (CADS).ResultsFifteen patients enrolled in the intervention before the study was closed early because of lack of efficacy. Median MDS and CADS increased after SC, suggesting increased hair loss (p < .001) and alopecia distress (p = .04). Only one participant was successful in preventing significant hair loss; the majority stopped SC before chemotherapy completion because of grade 3 alopecia (>50% hair loss).ConclusionSC may not be efficacious in preventing alopecia in Black women. Differences in hair thickness, hair volume, and limitations of cooling cap design are possible contributing factors.     

Status of Foot‐and‐mouth Disease in India

Foot‐and‐mouth disease (FMD) is endemic in India and causes severe economic loss. Status of FMD in the country for five fiscal years is presented. Outbreaks were more in number in 2007–2008 than 2010–2011. Three serotypes of FMD virus (O, A and Asia1) are prevalent. Serotype O was responsible for 80% of the confirmed outbreaks/cases, whereas Asia1 and A caused 12% and 8%, respectively. Geographical region‐wise assessment indicated varying prevalence rate in different regions viz; 43% in Eastern region, 31.5% in Southern region, 11.6% in North‐eastern region, 5% Central region, 4.4% Western region and 4% in Northern region. Highest number of outbreaks/cases was recorded in the month of September and lowest in June. Emergence and re‐emergence of different genotypes/lineages within the serotypes were evident in real‐time investigation carried out from time to time. Continues antigenic divergence in serotype A resulted in change in the vaccine strain in 2009. As on date, all genetic diversity within the serotypes is well tolerated by the vaccine strains. Unrestricted animal movements in the country play a major role in the spread of FMD.     

Transseptal Catheterization without Needle Puncture

Objective - The aim was to see if probing the fossa ovalis for transseptal puncture during balloon mitral valvuloplasty will reduce time consumed for the procedure. Design - Twenty-five patients had probing of fossa ovalis for left atrial entry (group I). In 30 patients (group II), standard needle puncture was done for left atrial entry. Puncture time and fluoroscopy time were noted and oxymetry was done. Later, a further 60 patients underwent probing of fossa ovalis for validation of the technique. Results     

Sheehan's syndrome: clinical profile, pituitary hormone responses and computed sellar tomography

Twenty patients with the typical clinical presentation of Sheehan's syndrome were studied. All had a severe degree of hypopituitarism. The circulating mean basal levels of thyroid hormones, Cortisol and prolactin were significantly lower (p< 0.05 to <0.02) compared to those in 50 age matched controls. The provoked pituitary responses to combined pituitary stimulation in 13 patients were markedly lower (p <0.02 to <0.001) than those in ten age matched control subjects. Sellar computed tomography revealed an empty sella in all the patients; partial in five and complete in the remaining. A secondary empty sella is considered a characteristic finding in the classical form of Sheehan's syndrome. (Aust NZ J Med 1993; 23: 26–31.)
