OBJECTIVE

This study compared the demographics, clinical profile, treatment, and outcomes of retinoblastoma patients seen at medical institutions in the Philippines between two time periods: 2010 to 2015 and 2016 to 2020.

METHODS

This was a multicenter, analytical, cohort study using review of medical charts and databases of retinoblastoma patients seen in 11 medical institutions from 2010 to 2020.

RESULTS

There were 636 patients (821 eyes) included in this study: 330 patients were seen in 2010 to 2015 while 306 in 2016 to 2020. More cases per annum were seen in the latter timeline. The number of patients with unilateral disease was not significantly different between the two time periods (p=0.51). Age at onset of symptom, age at initial consultation, and delay in consult were also not significantly different between the two time periods (p > 0.05). Patients had significantly different distributions of intraocular grades (p < 0.0001) and systemic staging (p < 0.0001) between the two time periods. Enucleation was the most common surgical treatment performed in both timelines. There was significant difference in the status of patients based on the need for systemic chemotherapy (p < 0.01). There was significant difference in outcome between the two time periods, including the proportions of living and deceased patients.

CONCLUSION

This study compared the most comprehensive data on retinoblastoma patients in the country. There was no improvement in early health seeking behavior based on similar age at initial consult and delay in consult. Enucleation remained the most common treatment mode as opposed to chemotherapy due to similar percentage of patients with unilateral disease, an indication for enucleation rather than chemotherapy.

Objective: To carry out the genetic characterization and evolutionary analysis of three avian orthoavulavirus 1 (AOAV-1) isolates from poultry workers with respiratory symptoms. Methods: Using Illumina MiSeq, whole-genome sequencing was carried out to assess the evolutionary dynamics of three AOAV-1 isolates. A phylogenetic and comparative analysis of all coding genes was done using bioinformatics tools. Results: Phylogenetic analysis and genetic distance estimation suggested a close relationship among human- and avian-originated velogenic strains of genotype XIII, sub-genotype XIII.2.1. Several substitutions in the significant structural and biological motifs were exclusively identified in the human-originated strains. Conclusions: To our knowledge, this is the first report of a velogenic AOAV-1 isolate from natural infection of the human upper respiratory tract. Our findings highlight the evolution and zoonotic potential of velogenic AOAV-1 in a disease endemic setting.

Objectives: To investigate trends of osteoporosis treatment rates, and factors affecting osteoporosis treatment after hip fracture admission within a single health care system in Hawaii. Methods: A retrospective chart review was conducted of patients aged 50 years or older and hospitalized for hip fractures between January 1, 2011 and December 31, 2019 at Hawaii Pacific Health, a large health care system in Hawaii. We collected data on basic demographics and osteoporosis medication prescription from electronic medical records. We evaluated trends of osteoporosis treatment rates and performed logistic regression to determine factors associated with osteoporosis treatment. Results: The mean for treatment rates for osteoporosis from 2011 to 2019 was 17.2% (range 8.8%-26.0%). From 2011 to 2019 there was a small increase in treatment rates from 16.3% in 2011 to 24.1% in 2019. Men were less likely to receive osteoporosis treatment after admission for hip fracture. Patients discharged to a facility were more likely to receive osteoporosis treatment. As compared to women, men who had a hip fracture were less likely to receive dual-energy X-ray absorptiometry scan, and osteoporosis medication before hip fracture admission. Conclusions The use of osteoporosis medication for secondary prevention after admission for hip fracture in Hawaii from 2011 to 2019 was low. However, there was a small increase in treatment rates from 2011 to 2019. Disparities in treatment of osteoporosis after hip fracture were noted in men. Significant work is needed to increase treatment rates further, and to address the disparity in osteoporosis treatment between men and women.

INTRODUCTION: Haze is a recurrent problem in Southeast Asia. Exposure to haze is linked to ophthalmic, respiratory and cardiovascular diseases, and mortality. In this study, we investigated the role of demographic factors, knowledge and perceived risk in influencing protective behaviours during the 2013 haze in Singapore. METHODS: We evaluated 696 adults in a cross-sectional study. Participants were sampled via a 2-stage simple random sampling without replacement from a large residential district in Singapore in 2015. The questionnaire measured the participant's knowledge, perceived risk and behaviours during the Southeast Asian haze crisis in 2013. Reliability and validity of the questionnaire were assessed using comparative fit index (≥0.96) and root mean square error of approximation (≤0.05). We performed structural equation modelling to examine the relationship between the hypothesised factors and protective behaviours. RESULTS: More than 95% of the individuals engaged in at least 1 form of protective behaviour. Knowledge was strongly associated with protective behaviours via direct effect (β=0.45, 95% CI 0.19-0.69, CONCLUSION Knowledge was associated with protective behaviours, suggesting the importance of public education. Efforts should target those of lower education level and smokers. The wearing of N95 masks correlates with uptake of other protective behaviours.

INTRODUCTIONDiabetes mellitus (DM) is a major cause of chronic kidney disease (CKD). The epidemiology of CKD secondary to type 2 DM (T2DM) (i.e. diabetic nephropathy (DN)) has not been well studied in Singapore, a multi-ethnic Asian population. We aimed to determine the prevalence of CKD in adult patients with T2DM.

MATERIALS AND METHODSWe conducted a cross-sectional study on patients (n = 1861) aged 21 to 89 years with T2DM who had attended the DM centre of a single acute care public hospital or a primary care polyclinic between August 2011 and November 2013. Demographic and clinical data were obtained from patients using a standard questionnaire. Spot urine and fasting blood samples were sent to an accredited hospital laboratory for urinary albumin, serum creatinine, HbA1c and lipid measurement. CKD was defined and classified using the 2012 Kidney Disease: Improving Global Outcomes (KDIGO) guidelines and classification.

RESULTSThe distribution by risk of adverse CKD outcomes was: low risk, 47%; moderate risk, 27.2%; high risk, 12.8%; and very high risk, 13%. The prevalence of CKD in patients with T2DM was 53%. Variables significantly associated with CKD include neuropathy, blood pressure ≥140/80 mmHg, triglycerides ≥1.7 mmol, body mass index, duration of diabetes, HbA1c ≥8%, age, cardiovascular disease, and proliferative retinopathy.

CONCLUSIONCKD was highly prevalent among patients with T2DM in Singapore. Several risk factors for CKD are well recognised and amenable to intervention. Routine rigorous screening for DN and enhanced programme for global risk factors reduction will be critical to stem the tide of DN.

We report a case of a diabetic patient with an infected leg wound leading to septicemia and abscess formation in the contra-lateral leg due to Streptococcus canis. This organism belongs to the Lancefield group G and is more commonly found in dogs. It is often mistaken for Streptococcus dysgalactiae which is a human strain of streptococci. Infections in humans are not common and usually involve infected wounds or ulcers and the surrounding soft tissue. In most reported cases, patients had close contact with domestic dogs and a pre-existing wound as a portal of entry. Our patient recovered after surgical debridement and drainage of abscess together with antibiotics. This organism is sensitive to common antibiotics like penicillin, amoxycillin, cephalosporins and erythromycin. The incidence of infections due to Streptococcus canis may be under-reported as laboratories may just report an isolate as group G streptococcus. Susceptible patients with wounds or ulcers should be counselled on proper wound care and advised to avoid or minimise contact with the family dog.

INTRODUCTIONThis study aims to review the results of hearing screens in newborns with cleft deformities.

MATERIALS AND METHODSA retrospective audit of 123 newborns with cleft deformities, born between 1 April 2002 and 1 December 2008, was conducted. Data on the results of universal newborn hearing screens (UNHS) and high-risk hearing screens, age at diagnosis, severity/type of hearing loss and mode of intervention were obtained from a prospectively maintained hearing database.

RESULTSThirty-one of 123 newborns (25.2%) failed the first automated auditory brainstem response (AABR). Seventy percent of infants (56 out of 80) who passed the UNHS failed the high-risk hearing screens which was conducted at 3 to 6 months of age. Otolaryngology referral rate was 67.5% (83/123); 90.3% of 31 newborns who failed the first AABR eventually required otolaryngology referrals. Incidence of hearing loss was 24.4% (30/123; 25 conductive, 2 mixed and 3 sensorineural), significantly higher than the hospital incidence of 0.3% (OR: 124.9, 95% CI, 81.1 to 192.4, P <0.01). In terms of severity, 8 were mild, 15 moderate, 5 severe, 2 profound. Eighteen out of 30 infants (60%) were detected from the high-risk hearing screens after passing the first AABR.

CONCLUSIONThese newborns had a higher risk of failing the UNHS and high-risk hearing screen. There was a higher incidence of hearing loss which was mainly conductive. Failure of the first AABR was an accurate predictor of an eventual otolaryngology referral, suggesting that a second AABR may be unnecessary. High-risk hearing screens helped to identify hearing loss which might have been missed out early on in life or which might have evolved later in infancy.
