Abstract
PURPOSE To develop prediction models for severe retinopathy of prematurity (ROP) based on risk factors in preterm Thai infants to reduce unnecessary eye examinations in low-risk infants. METHODS This retrospective cohort study included preterm infants screened for ROP in a tertiary hospital in Bangkok, Thailand, between September 2009 and December 2020. A predictive score model and a risk factor-based algorithm were developed based on the risk factors identified by a multivariate logistic regression analysis. Validity scores, and corresponding 95% confidence intervals (CIs), were reported. RESULTS The mean gestational age and birth weight (standard deviation) of 845 enrolled infants were 30.3 (2.6) weeks and 1264.9 (398.1) g, respectively. The prevalence of ROP was 26.2%. Independent risk factors across models included gestational age, birth weight, no antenatal steroid use, postnatal steroid use, duration of oxygen supplementation, and weight gain during the first 4 weeks of life. The predictive score had a sensitivity (95% CI) of 92.2% (83.0, 96.6), negative predictive value (NPV) of 99.2% (98.1, 99.6), and negative likelihood ratio (NLR) of 0.1. The risk factor-based algorithm revealed a sensitivity of 100% (94, 100), NPV of 100% (99, 100), and NLR of 0. Similar validity was observed when "any oxygen supplementation" replaced "duration of oxygen supplementation." Predictive score, unmodified, and modified algorithms reduced eye examinations by 71%, 43%, and 16%, respectively. CONCLUSIONS Our risk factor-based algorithm offered an efficient approach to reducing unnecessary eye examinations while maintaining the safety of infants at risk of severe ROP. Prospective validation of the model is required.

Abstract
PURPOSE To validate Postnatal Growth and Retinopathy of Prematurity (G-ROP) criteria for Thai infants. STUDY DESIGN A retrospective review of infants receiving ROP screening during 2009-2020. METHODS Baseline characteristics, clinical progression and final ROP outcomes were collected. G-ROP was applied to infants who met at least one of the following 6 criteria: birth weight (BW) below 1051 g, gestational age (GA) under 28 weeks, weight gain (WG) less than 120 g during postnatal day 10-19, WG less than 180 g during day 20-29, WG less than 170 g during day 30-39 and hydrocephalus. RESULTS A total of 684 infants (boys, 53.4%) were included. Median (IQR) BW was 1200 (960-1470) grams and median GA was 30 (28-32) weeks. Prevalence of ROP was 26.6%, with 28 (4.1%) having type 1, 19 (2.8%) type 2 and, 135 (19.7%) having other ROP. Treatment was performed in 26 infants (3.8%). Sensitivity of G-ROP to include type 1, 2 or treatment-requiring ROP cases was 100% with 36.9% specificity, excluding 235 (34.4%) cases of unnecessary screening. To adjust for our setting of initial eye examination at 4 weeks' postnatal date, the last 2 criteria of G-ROP were replaced by the occurrence of grade 3 or 4 intraventricular hemorrhage (IVH). This modified G-ROP criteria yielded 100% sensitivity, 42.5% specificity and excluded 271 (39.6%) cases of unnecessary screening. CONCLUSION G-ROP criteria can be applied to our hospital setting. Occurrence of IVH grade 3 or 4 was proposed as an alternative in modified G-ROP criteria.

Abstract
Autoimmune retinopathy (AIR) is a rare immune-mediated inflammation of the retina. The autoantibodies against retinal proteins and glycolytic enzymes were reported to be involved in the pathogenesis. This retrospective cohort study assessed the antiretinal autoantibody profiles and their association with clinical outcomes of AIR patients in Thailand. We included 44 patients, 75% were females, with the overall median age of onset of 48 (17-74, IQR 40-55.5) years. Common clinical presentations were nyctalopia (65.9%), blurred vision (52.3%), constricted visual field (43.2%), and nonrecordable electroretinography (65.9%). Underlying malignancy and autoimmune diseases were found in 2 and 12 female patients, respectively. We found 41 autoantibodies, with anti-α-enolase (65.9%) showing the highest prevalence, followed by anti-CAII (43.2%), anti-aldolase (40.9%), and anti-GAPDH (36.4%). Anti-aldolase was associated with male gender (P = 0.012, OR 7.11, 95% CI 1.54-32.91). Anti-CAII showed significant association with age of onset (P = 0.025, 95% CI - 17.28 to - 1.24), while anti-α-enolase (P = 0.002, OR 4.37, 95% CI 1.83-10.37) and anti-GAPDH (P = 0.001, OR 1.87, 95% CI 1.32-2.64) were significantly associated with nonrecordable electroretinography. Association between the antibody profiles and clinical outcomes may be used to direct and adjust the treatment plans and provide insights in the pathogenesis of AIR.

Abstract
BACKGROUND Although ultraviolet A1 (UVA1) phototherapy is available for nearly 30 years, only few studies have been conducted for plaque-type psoriasis. OBJECTIVES To determine the efficacy and safety of UVA1 phototherapy in psoriasis by assessing the clinical and histological outcomes. METHODS This open study enrolled 15 patients with moderate to severe plaque-type psoriasis. All of the patients had skin type IV. A whole-body UVA1 device consisting of 24 lamps, was irradiated at a medium dose of 50 J/cm2 three-times weekly for 30 sessions. Topical and systemic psoriasis treatments were discontinued before and during treatment; patients could only use emollients and antihistamines until 1-month post-completion. Psoriasis Area and Severity Index (PASI) scores were determined at baseline; at sessions 10th, 20th and 30th; and 1 month after treatment. Four-millimetre punch biopsies were obtained from the same psoriasis lesion at baseline and session 30th. Changes in histopathological gradings and polymorphonuclear, lymphocyte and Langerhans cell numbers were monitored. RESULTS Twelve patients completed the study. The mean age was 41.3 years (range: 25-71). The median PASI scores at baseline, session 30th and 1-month post-treatment were 16 (8.2, 43.3), 11 (4.4, 43.3) and 9.2 (2.7, 36.4), respectively. Although the PASI scores had improved significantly by 1-month post-treatment (P = .006), the histological parameters demonstrated minimal changes. All patients tolerated the phototherapy well and the most common side effect was skin tanning. CONCLUSIONS While medium-dose UVA1 phototherapy demonstrated some efficacy in moderate to severe plaque-type psoriasis. However, it might not be an excellent choice.

Abstract
BACKGROUND Previous studies showed that significant proportion of medical students consumed caffeine to face sleep-deprived daily schedules. OBJECTIVE To monitor the trend of caffeinated-beverage consumption among Siriraj medical students as well as to study possible factors associated with caffeine dependency. MATERIAL AND METHOD The questionnaire was distributed to a class of medical students for 2 consecutive years. Statistical analysis was performed for descriptive purpose. RESULTS 269 (89.7%) and 225 (74.5%) questionnaires were returned in year 1 and year 2, respectively 16.2% refused to take caffeine-beverages totally. 13% of those who consumed caffeinated-beverages developed caffeine dependence. From logistical analysis, positive history of smoking-family member and female sex were the only other two factors associated with caffeine dependency (OR 2.19, 95% CI 1.04-4.61 and 1.76, 95% CI 1.01-3.07, respectively). Other investigated factors included: exercise (p = 0.08); sleep hours (p = 0.24); reading beverage labels (p = 0.87); alcohol consumption (p = 0.59); class performance (p = 0.87); family member coffee-drinking habits (p = 0.66);family member alcohol-drinking habits (p = 0.18); and family income (p = 0.06). CONCLUSION Caffeinated-beverage consumption was common among Siriraj medical students. No significant change was detected in the pattern of caffeinated-beverage consumption within the study period. Positive history of smoking family members and female sex were found as the only other two factors correlated with caffeine dependency.

Abstract
Background A strong inverse relationship of functional limitation and socioeconomic status has been established in western ageing society. Functional limitation can be related to chronic diseases, disuse, cognitive decline, and ageing. Among chronic diseases in the Thai population, cerebrovascular diseases, diabetes, and arthritis are common. These factors are known to contribute to disability and poor quality of life in the elder population. Neuropsychiatric problems, cognitive decline, dementia, and cultural issues in elderly people also can alter the quality of life of the elderly. Methods The Dementia and Disability Project in Thai Elderly (DDP) aims at comprehensively assessing community dwelling Thai elderly to understand the relationship between disability and motor function, neuropsychiatric symptoms, cognitive function, and chronic diseases. The DDP is the first study to look at the prevalence and etiology of dementia and of mild cognitive impairment (MCI) in Thai elders and to explore the relationship of cognition, disability, small vessel diseases and cortical degeneration with neuroimaging in Thai elderly people. 1998 Thai elders were screened in 2004–2006 and diagnosed as having MCI or dementia. 223 elders with MCI or dementia and cognitively normal elderly had brain magnetic resonance imaging (MRI) or at baseline. 319 elders from the 3 groups had blood tests to investigate the risks and possible etiologies of dementia including genotyping at baseline. Results The mean age of elders in this study is 69.51(SD=6.71, min=60, max=95) years. 689(34.9%) are men and 1284(65.1%) are women. Mean body weight was 58.36(SD=11.20) kgs. The regression model reveals that performance on gait and balance and serum triglyceride predicts activity of daily living performance (adjusted r2 = 0.280, f=2.644, p=0.003). The majority of abnormal gait in Thai elders was lower level gait disturbance. Only 1.5% (29/1952) had highest level gait disorders. 39.5% of 1964 subjects were free of chronic diseases. Treatment gap (indicating those who have untreated or inadequate treatment) of diabetes mellitus and hypertension in Thai elders in this study was 37% and 55.5% respectively. 62.6% of Thai elders have ApoE3E3 allele. Prevalence of positive ApoE4 gene in this study is 22.85%. 38.6% of Thai elders who had MRI brain study have moderate to severe white matter lesions. Conclusion The large and comprehensive set of measurements in DDP allows a wide-ranging explanation of the functional and clinical features to be investigated in relation to white matter lesions or cortical atrophy of the brain in Thai elderly population. An almost 2 year follow up was made available to those with MCI and dementia and some of the cognitively normal elderly. The longitudinal design will provide great understanding of the possible contributors to disability in the elderly and to the progression of cognitive decline in Thai elders.

Abstract
BACKGROUND Activities of daily living (ADL) vary across cultures, and measure of ADL needs to be specific to the population under study. We developed an ADL measure for Thai elderly with dementia and investigated the reliability and validity of this instrument. MATERIALS AND METHODS Item construction was accomplished with a panel of neurologists and a rehabilitation medicine physician. One hundred eighty-one subjects were interviewed using the Thai ADL measure. Of this sample, one hundred fifty-nine had dementia according to the Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria. These data were analyzed for internal consistency; concurrent validity was determined by comparison with the Barthel Index, Functional Assessment Questionnaire (FAQ), Thai Mental State Exam (TMSE), and Clinical Dementia Rating (CDR) scale; and discriminant validity was determined by comparison with the Neuropsychiatric Inventory (NPI). Thirty subjects were tested to determine interrater and test-retest reliability. RESULTS Thai ADL measure was composed of six basic ADL and seven instrumental ADL. It had high correlation with TMSE scores (r = -.69), CDR scores (r = .81), Barthel Index scores (r = -.80), and FAQ scores (r = .88), and moderate correlation with NPI scores (r = .46). The instrument had high test-retest reliability (intraclass correlation coefficient [ICC] = .92, .89) and high interrater reliability (ICC = .96, .93). CONCLUSION The Thai ADL scale is easy to use and it has high reliability. It had high concurrent validity with previously published ADL scales. The methodology used to develop the Thai ADL scale can provide a model for creating culturally competent ADL scales.

Abstract
BACKGROUND Studies taken from different hospitalized patient populations, environments, and geographic regions reveal differences in the numbers and species of organisms colonizing the skin. Our aim was to determine the types and amounts of skin flora, and examine the factors associated with variations in microbial skin flora in patients in Thailand. METHOD We studied 350 outpatients and 500 inpatients at Siriraj Hospital in Bangkok, Thailand. The skin at the forearm and the sternum of each patient was cultured by contact plate technique. RESULTS The number of skin flora colony-forming units (CFUs) were correlated to the site of sampling. There was a significant correlation of CFUs between samples from the forearm and the sternum in patients who were hospitalized (r = 0.6; P <.001) and in outpatients (r = 0.5; P <.001). The numbers of micro-organisms on the sternum was significantly greater than the number cultured from the forearm for all patients. Inpatients had significantly more organisms on the the forearm and sternum compared with outpatients. High counts (CFUs > 600) were found more frequently in patients who were hospitalized; had chronic obstructive pulmonary disease, diabetes mellitus, or autoimmune diseases; and were undergoing operation and receiving antibiotics. Acinetobacter spp and methicillin-resistant Staphyloccoccus aureus were found more frequently in patients who were hospitalized. CONCLUSION Skin flora of patients in tertiary care hospitals in Thailand has higher CFUs, and A baumannii is prevalent, especially in patients who are hospitalized.

Abstract
OBJECTIVE To investigate an association between endogenous estradiol (E(2)) levels and cognition and behavior in elderly individuals. PATIENTS We studied 135 community-based men and women aged 52 to 85 years in urban Bangkok, Thailand; 72 had dementia and 63 did not. MATERIALS AND METHODS Dementia was diagnosed using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria after appropriate investigations. Blood samples for assay were collected in the morning after 6 hours of fasting. Levels of E(2) were measured by radioimmunoassay (double antibody technique). The Thai version of the Mini-Mental State Examination was used to assess cognition; the Neuropsychiatric Inventory was used to assess neuropsychiatric symptoms; and the Functional Assessment Questionnaire was used to assess instrumental activities of daily living. RESULTS There was no correlation between age and level of E(2) in either men or women. Individuals with lower estrogen levels had more behavioral disturbances (men: r = -0.467, n = 45; P =.001; women: r = -0.384, n = 90; P<.001) and worse cognition (men: r = 0.316, n = 45; P =.03; women: r = 0.243, n = 90; P =.02) and function (men: r = -0.417, n = 45; P =.004; women: r = -0.437, n = 90; P<.001). The threshold level of endogenous E(2) in elderly individuals for the risk of developing dementia was less than 15 pg/mL (<55 pmol/L) in men and less than 1 pg/mL (<4 pmol/L) in women. CONCLUSION Lower E(2) levels are correlated with poor cognitive, behavioral, and functional status in older individuals.

Abstract
OBJECTIVE To examine the association of physical and biochemical risk factors for dementia and cognitive status in an urban population based Thai elderly. MATERIAL AND METHOD This study was part of an integrated health research project from 1997 to 1999. Subjects were 550 elders who lived in a community within 10 km from Siriraj Hospital, Bangkok, Thailand. They were 55 years and older. Thai mental state examination (TMSE) was applied to all subjects as the screening test for dementia. Those who scored less than or equal to 24 out of 30 were categorised as having cognitive impairment or suspected of having dementia, and they were then examined in detail for the diagnosis of dementia using the DSM IV criteria. Blood pressure and body weight were recorded. Blood was drawn for biochemical and haematological analysis including the serology for syphilis and thyroid function test as the basic screening investigation for dementia. Descriptive data, expressed as the mean, standard deviation, Pearson Chi square and ANOVA tests were analysed with SPSS 9.0 in the study. RESULTS Of 550 subjects, 261 (47.45%) were classified as the normal subjects group, 49 (8.91%) as the cognitively impaired group, and 240 (43.82%) as the dementia group. 377 subjects (68.55%) were female and the distribution of females in each subgroup ranged from 63.3-75.5 per cent. The mean age in the normal group was 67.47 +/- 6.05 years, the cognitively impaired group was 70.14 years and the dementia group was 69.63 +/- 9.21 years. Systolic blood pressure (BP), diastolic BP, serum cholesterol, SGOT, GGT, serum albumin, haemoglobin, MCHC, neutrophil counts and weight were statistically significant factors that were associated with cognitive status. Both systolic and diastolic BP were high in the higher cognitive status group. Serum albumin, serum cholesterol levels and body weight were also higher in the high cognitive status group. CONCLUSION This study demonstrated an association between nutritional status and cognitive status in Thai elderly. Poorer nutritional factor in lower cognitive function individuals might explain a lower of both systolic and diastolic BP in the dementia subjects compared to the healthy subjects.

Abstract
OBJECTIVE To survey the prevalence of cognitive impairment in the elderly and to estimate the prevalence of dementia in the community dwelling Thai population. To assess the psychometric property of Thai Mental State Examination (TMSE). MATERIAL AND METHOD We conducted a countrywide survey of 3,177 Thai elderly who were 60 years old and over from 1995 to 1997. Medical history and ability to carry out daily activities were taken by trained medical personnel. Thai Mental State Examination (TMSE) was used for cognitive study. Every elderly person involved in this study was examined by either an internist or a neurologist. Blood was taken for haematological and biochemical analysis. SPSS 6.0 was the main statistical analysis of the data. RESULTS Three thousand one hundred and seventy seven elderly people were enrolled in this study, thirty eight point eight per cent were male and sixty one point two per cent were female. There was correlation between age, education and TMSE (r=-0.345, r=0.473, p<0.001). We found no correlation between TMSE, mean arterial blood pressure (BP), systolic BP, diastolic BP, haematocrit, cholesterol, triglyceride, blood sugar and syphilitic serology. Multiple cut off points of TMSE was proposed to utilise the twenty fifth percentile in each five yearly age interval. Those who were under the 25th percentile of TMSE and had impaired daily activities were diagnosed as dementia. The prevalence of dementia was 9.88 percentiles in our study. CONCLUSION Dementia is a common problem in the Thai elderly. As treatment has become available for several etiologies of dementia, early detection and assessment of dementia with a cognitive screening test are essential. Public education to distinguish between dementia and old age needs to be emphasised.

Abstract
UNLABELLED The association between ApoE E4 and dementia is reported in Alzheimer's disease and other dementia such as in multi-infarct dementia. OBJECTIVES To examine the association between apolipoprotein E genotype (ApoE) and dementia in Thai elderly and patients to examine the alleles frequencies of ApoE in a Thai population. MATERIAL AND METHOD Seventy-eight cases and ninety-four controls from a community based population were recruited. Their ages were all over 50 years. Dementia was diagnosed by DSM IV criteria. Blood was taken and stored for DNA extraction and for restriction enzyme analysis of ApoE genotype. Descriptive analysis and odds ratios from SPSS 9.0 program were used in this study. RESULTS Alleles frequencies of ApoE E2, E, E4 in normal controls were 0.03, 0.80, 0.17 and alleles frequencies of ApoE E3, E4 in dementia subjects were 0.71 and 0.29, respectively. Odds ratios for dementia risk of apolipoprotein genes were as follows: 0.62 for ApoE E3 and 1.98 for ApoE E4. In this study, forty-two dementia subjects had Alzheimer's disease. Fifty nine point five per cent of Alzheimer's disease subjects carried ApoE E4 (positive predictive value is 0.60). CONCLUSION Thai elderly carry ApoE genotype distribution similar to that reported in other ethnic groups. Bearing ApoE E4 gene increases the risk of developing dementia. The use of ApoE genotyping can only be a diagnostic adjunct for Alzheimer's disease.

Abstract
The effectiveness and adverse effects of continuous epidural analgesia was studied in 104 patients undergoing thoracic operations at Siriraj Hospital. Patients were divided into 3 groups according to the type of surgical approach and the technique of epidural analgesia. Group 1 patients (n = 72) received thoracic epidural block using bupivacaine and morphine combined with light general anesthesia for exploratory thoracotomy; group 2 patients (n = 21) received the identical anesthetic technique, the operation was achieved through median sternotomy; group 3 patients (n = 11) had a similar type of operation to group 1, the anesthetic technique was lumbar epidural block using morphine and combined with light general anesthesia. Continuous epidural morphine infusion was given 0.1-0.4 mg/h during postoperation in all patients for providing adequate pain relief. The results revealed that a 10 cm visual analogue scale (VAS) pain scores were satisfactory and comparable in all groups. Lumbar epidural patients consumed a significantly larger dose of morphine than thoracic epidural groups (P < 0.01). Intraoperative hypotension occurred 43.05 per cent and 19.05 per cent in group 1 and 2, but none was found in group 3 (P < 0.05). Postoperative respiratory depression was found 54.16 per cent in group 1, 33.33 per cent in group 2 and 9.09 per cent in group 3 (P < 0.05), and was mostly mild to moderate, except three patients in group 1 and one in group 2 who needed mechanical ventilatory support. There were no differences among the groups in the incidence of nausea/vomiting and pruritus. It is concluded that both thoracic and lumbar epidural morphine provide excellent postthoracotomy pain relief, whereas, respiratory depression is more common with thoracic than lumbar epidural morphine.

Abstract
BACKGROUND A knowledge of the epidemiology of Pneumocystis carinii pneumonia (PCP) is important for the development of a strategy for primary PCP prophylaxis and empiric treatment for severe pneumonia in HIV-infected children. However, little is known about the epidemiology of PCP in developing countries. Objective. To measure the relative rate of PCP among hospitalized HIV-infected children with severe pneumonia in Bangkok and evaluate the effect of a strategy of primary PCP prophylaxis in HIV-exposed infants. METHODS All HIV-infected children hospitalized from January, 1996, to December, 1997, for severe pneumonia were investigated for PCP with the use of specimens obtained from bronchoalveolar lavage, endotracheal aspiration or lung tissue necropsy. Characteristics associated with severe pneumonia were described, and the differences between PCP and non-PCP in these severely ill children were analyzed. In June, 1996, a strategy of primary PCP prophylaxis using trimethoprim-sulfamethoxazole in all HIV-exposed infants from 1 to 6 month of age was initiated in our institution. The effect of this strategy was evaluated. RESULTS Of 279 hospitalized HIV-infected children 128 (46%) were diagnosed with pneumonia and 26 (20%) of these had severe pneumonia. P. carinii was identified in 9 (35%) children with severe pneumonia. After June, 1996, the rate of severe pneumonia among all hospitalized children decreased from 16% from January through June, 1996, to 7% from July, 1996, through December, 1997 (P = 0.02). Cases of PCP decreased from 9 in 1996 to zero in 1997. The percentage of HIV-infected children receiving PCP prophylaxis at the time of admission increased from 53% before June, 1996, to 72% in late 1997 (P = 0.04). The overall percentage of patients with severe pneumonia receiving PCP prophylaxis at the time of admission was 34%. Breakthrough PCP occurred in 2 children with poor compliance. Patients with PCP were significantly younger than those without PCP (mean age, 10.6+/-10.6 vs. 29.8+/-28.3 months, P = 0.02). CONCLUSION PCP occurred in one-third of cases of severe pneumonia in HIV-infected children in Bangkok. The data suggest that PCP prophylaxis can prevent both PCP and non-PCP.
