OBJECTIVE: To determine the prevalence of menstrual and reproductive dysfunction among subjects who have undergone radioiodine treatment for thyroid carcinoma.
METHODOLOGY: This study enrolled adult women with Differentiated Thyroid Carcinoma who received the treatment at age 40 years and below. Data was processed using SAS program and evaluated using Fischer's test and Wilcoxon test.
RESULTS: The study enrolled 46 women. Three reported cycle irregularities, 4 reported changes in amount of bleeding and 1 had amenorrhea. The prevalence rate of menstrual abnormalities was 15.2%. These women received a significantly higher dose of radioactive iodine (RAI) (120 vs. 110 mCi, p = 0.0064). Eleven women tried to conceive and there were 5 births to 5 different subjects after radiation. There were no congenital anomalies and 1 miscarriage. Four women were menopausal with an average age of 44.4 years old.
CONCLUSION: This study showed that the prevalence of menstrual disturbances after high dose radioactive iodine treatment among thyroid cancer patients is 15.2%. The affected group received a significantly higher dose of radioactive iodine compared to the unaffected group.

BACKGROUND: Studies have shown that diabetes increases the prevalence and severity of periodontitis. Furthermore, among patients with Type 2 Diabetes Mellitus (DM), poorer glycemic control was found to be associated with poorer periodontal health.
OBJECTIVE: To determine the prevalence of periodontitis and its association with glycemic control among Filipino patients with Type 2 DM.
DESIGN: Cross-sectional study
MATERIALS AND METHODS: Diagnosed Type 2 DM patients 35 years and above were recruited from the out-patient clinics of St. Luke's Medical Center from June-October 2009. Periodontitis was evidenced by the presence of ?3mm probing depth and ?3mm periodontal attachment loss at the same site. Periodontitis severity was classified based on probing depth and furcation involvement. Glycemic control was assessed by laboratory assay for HbA1c grouped into <7% and ?7%. Association between glycemic cont rol and periodontitis and severity of  periodontitis were determined using Pearson chi square test for independence. A multiple logistic regression analysis was performed to determine the association of glycemic control with the presence of periodontitis, controlling for the effects of selected indicators. Level of significance was set at ?=0.05.
RESULTS: A total of 192 subjects were analyzed. Prevalence of periodontitis among the Type 2 DM population studied was 68.23%. In this study, we found out that for those whose length of time since last dental check-up was >1 year, the odds of having periodontitis is 3.8 times higher (95% CI 1.45-9.76, p-value 0.007) among subjects with HbA1c ?7% compared to those with HbA1c <7%.
CONCLUSION: Our findings suggest that periodontitis is prevalent among the Filipino Type 2 DM population studied. In this study, it is the interaction of both HbA1c ?7% and length of time since last dental check-up >1 year that resulted in a statistically significant association with periodontitis.

BACKGROUND: Secondary hyperparathyroidism (SHPT) can lead to significant morbidity, mortality, and additional healthcare resource ut i l i zat ion in chronic k idney disease. Baseline prevalence data is highly required. This study aims to determine the prevalence of secondary hyperparathyroidi sm (SPTH) in pat ient s wi th Type 2 diabetes undergoing hemodialysis.
MATERIALS AND METHODS: We reviewed all medical records of patients whose chronic kidney disease (CKD) was due to Type 2 diabetes mellitus and are undergoing chronic hemodialysis from 2000 to 2009. Excluded were those who underwent hemodialysis due to acute renal failure or for chronic renal failure due to other causes other than diabetic nephropathy (e.g. hypertensive nephropathy, chronic glomerulonephritis, etc). Data collected include age, sex, body mass index, bone markers, intact PTH, and urea reduction rate.
RESULTS: The age and sex adjusted period prevalence of secondary hyperparathyroidism was 28.9%, commonly seen in the 5th to the 6th decade of life. Patients with SPTH had higher serum intact PTH, higher total calcium level (mean 9.05 versus 8.6, p=.026) and a higher urea reduction rate (mean 54.1 versus 45.2, p=.045). There was a longer duration of hemodialysis sessions among those with secondary hyperparathyroidism (mean 2.4 years versus 1.78 years, p=.004). Dialysis was likewise more adequate.
CONCLUSION: Prolonged diabet ic kidney di sease is associated with secondary hyperparathyroidism for which a more aggressive monitoring of calcium and phosphorus imbalance is required.

Tuberculosis (TB) of the thyroid gland is rare, with acute abscess formation being the least common form of presentation. As such, TB of the thyroid may be overlooked as an initial clinical impression. A careful approach by history, physical examination, laboratory testing and radiologic imaging may aid in defining the etiology of the thyroid abscess, but these remain nonspecific. An accurate diagnosis may only be made by histologic examination. We present a case of a tuberculous abscess of the thyroid gland in a 37-year-old female. TB of the thyroid should also be considered when evaluating patients presenting with a painful thyroid nodule.

INTRODUCTION: Diabetes mellitus is rapidly increasing worldwide but the greatest increase is expected in developing countries including the Philippines. It is of public health concern to monitor countrywide prevalence of diabetes as it leads to significant cardiovascular-related mortality as well as significant complications such end stage renal disease, blindness, lower leg amputations and blindness.
METHODOLOGY: This is a national survey to estimate the prevalence of diabetes and pre-diabetes using the criteria of the World Health Organization through a stratified multi-stage sampling design representing each of the 17 regions in the country.
RESULTS AND DISCUSSION: The national prevalence of diabetes in the year 2008 was 7.2% (6.5-7.9); impaired glucose tolerance 7.0% (6.1-7.8) and impaired fasting glucose was 2.2% (2.2-3.1). There was a greater prevalence of individuals with diabetes in the urban areas at 8.5% (7.5-9.5) compared to the rural areas at 5.7% (4.6-6.8). Diabetes is slightly more preponderant among females at 7.4% (6.4-8.3) compared to males at 7.0% (6.1-8.0).
CONCLUSION: The prevalence of diabetes mellitus in the Philippines is rising with the prevalence in 2008 at 7.2%. The prevalence of pre-diabetes exceeds that of diabetes mellitus at approximately 10.2%.

Objective. Previous studies have demonstrated the role of genetic susceptibility in the pathogenesis of diabetic nephropathy. The study aimed to determine the frequencies of angiotensin I-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism in a pilot population of Filipino type 2 diabetic patients and normal controls. Methods. An analysis of the ACE gene polymorphism was performed in 42 diabetic patients with and without nephropathy, and 24 normal controls. The analysis was done using polymerase chain reaction, restriction enzyme digestion, and gel electrophoresis techniques to determine the polymorphism (II, DD or ID). Independent T-tests and chi-square tests were used to compare clinical characteristics, and logistic regression analysis was done to determine odds ratio for development of nephropathy. Results. The ID polymorphism of the ACE gene was more frequent (52.4%) in patients with diabetic nephropathy (n=21). In those without nephropathy (n=21), II was more common (61.9%). ID was the more frequent genotype in the normal controls (n=24) (58.3%). The odds of developing diabetic nephropathy were increased by 4.8 times in those with ID polymorphism, and 2.9 times in those with DD. Conclusion. The D allele was more common in patients with diabetic nephropathy, similar to the observation in South Indian patients. Since the study involved only a small pilot group, studies on a larger population is needed to establish the hypothesized role of the D allele in susceptibility to diabetic nephropathy in Filipinos.

BACKGROUND: Glutathione due to its favorable side effect of skin whitening has been used by cosmetic centers and by individuals buying it as an over the counter supplementation. Because of this, this compound is prone to misuse. To date, there are limited studies on the adverse effects of exogenous supplementation of glutathione.
OBJECTIVE: To determine the prevalence of thyroid dysfunction among individuals taking oral and intravenous glutathione
DESIGN: Cross-sectional study
METHODS:Healthy Filipino subjects, 21 to 50 years of age, currently taking oral or intravenous glutathione, with no preexisting/ known thyroid disease and history of radiation exposure, and not taking medications with known effect on thyroid function were included in the study. Blood extraction for thyroid function test and thyroid ultrasound were conducted.
RESULTS: A total of 36 subjects were analyzed with a mean age of 36.3±8 years, 86 percent were female. High dose glutathione (1000mg or more per day) was taken in by nine subjects (25%) while 27 subjects (75%) took doses below the recommended range (less than 1000ng per day). The prevalence of abnormal thyroid function was 5.56 percent (n=2). Both cases were taking low dose glutathione supplementation. No abnormal thyroid function was seen with higher doses of glutathione. No significant relationship was found between the duration of glutathione supplementation with thyroid function status. Thyroid stimulating hormone (TSH) levels were slightly higher among those taking high dose glutathione (mean=1.08 versus 1.04, p=.81). There was no significant differences in the duration and dose of supplementation with the size of the gland.
RECOMMENDATION:The direct effect of L-glutathione supplements on thyroid function must be established using a longitudinal prospective study design. We also propose a group to serve as a negative control during the comparisons.

INTRODUCTION: While waist circumference (WC) is widely used as an index for visceral fat accumulation and purportedly the primary pathology responsible for the metabolic syndrome (MS), its proposed cut-off value varies depending on the disparate diagnostic criteria used as well as on the gender, race and ethnic group being evaluated. Due to the strong association between MS and central obesity, waist circumference should be incorporated into the routine physical exam when assessing cardiovascular disease and diabetes risk. Currently however, there is no standard location for the measurement of WC. On literature review, we found no scientific rationale for preferring any one WC site to the others hence, this study.
OBJECTIVE: This study aims to (1) determine waist circumference measurement var iat ions among MS patients, (2005 NCEP-ATP III/AHA/NHLB criteria), at three levels: (A) umbilical level, (B) midline level (between the inferior margin of the ribs and the superior border of the iliac crest) and (C) level of the superior border of the iliac crest.
RESEARCH DESIGN AND METHODS: Across - sectional analytical study among adult patients, aged 40 to 69 years, diagnosed with MS using 2005 NCEP-ATP III/AHA/ NHLB criteria seen at the Philippine General Hospital, as part of the Asia-Oceania Survey on Metabolic Syndrome and Diabetes initiated by the Japan Diabetes Society.
RESULTS: A total of 187 MS individuals were included in the study (56% females). Both males and females were obese stage 1 (25.5 kg/m2 and 26.7 kg/m2 respectively). The mean WC measurements at level A in men was 92.9 cm (81.36 - 104.44 cm) and 93.83 cm (83.4 - 104.26 cm) in women; at level B, the mean WC in men was 90.73 cm (75.49 - 105.97 cm) and 91.51 cm (80.62 - 102.4 cm) in women; and at level C, the mean WC in men was 93.5 cm (81.97 - 105.03 cm) and 95.12 cm (85.11 - 105.13 cm) in women. Results showed that WC measurements at three levels did not significantly differ among MS patients when stratified to age and sex. However, when waist circumference was measured at three levels among all patients with MS, there was significant difference in WC taken at level B and level C (Sig = 0.009). Waist circumference at level A was similar and less variable to WC level B than WC at levelC.
CONCLUSIONS: Among patients with MS as defined by NCEPATP III/AHA/NHLB criteria, waist circumference at level B (midpoint level between the lower ribs and superior border of the iliac crest) was smaller than waist circumference at level A (umbilical level) and smaller than level C (superior border of the iliac crest) (WCB < WCA < WCC). There was greater variability in mean WC measurements at level B and level C. Mean WC measurements at level A (umbilical level) and level B (midpoint level) were similar and less variable and may be a better waist circumference measurements to level C (superior border of the iliac crest).

BACKGROUND:The national prevalence of goiters in the Philippines was 3.7% in 1987 and 6.7% in 1993. Since then, there has been no follow-up survey on goiter prevalence, nor has there been any national survey on the prevalence of abnormal thyroid dysfunction. The PhilTiDeS is a survey on the prevalence of both goiters and thyroid disorders in the Philippines.
OBJECTIVES:To determine the prevalence of various categories of abnormal thyroid dysfunction among the Filipino non-pregnant adult population and to describe the prevalence of thyroid enlargement in the Philippines in relation to thyroid dysfunction status.
MATERIALS AND METHODS:The PhilTiDes was a substudy of the 2008 National Nutrition and Health Survey (NNHeS), which covered all 17 regions and 80 provinces of the Philippines. It included all Filipino adults 20 years and older, who are non-pregnant and non-lactating. A standard questionnaire was used to collect data on previous diagnosis and current treatment for thyroid disorders, and neck examination by trained field personnel was done to assess the presence of goiter. Blood was extracted, processed and sent to an accredited laboratory for free T4 and TSH testing using micro-particle enzyme immunoassay.
RESULTS: A total of 4897 persons had thyroid function tests. Of these, 417 (8.53%) had thyroid function abnormalities with the most common abnormality being subclinical hyperthyroidism occurring in 5.33%. The other categories had the following prevalence: true hyperthyroidism 0.61% ; true hypothyroidism 0.41%; and subclinical hypothyroidism 2.18%. Majority of the population 4480 (91.47%) had normal thyroid function tests. Of those with subclinical hyperthyroidism, 55% are females with mean age of 48 years (95% CI 45.9-50.1 years) compared with the volunteers with normal thyroid function who were younger (mean age of 43.1, 95% CI 42.5-43.6 years). Out of the 7,227 volunteers who responded to the survey and clinical examination, a total of 674 (8.9%) had goiters. Out of the 674 subjects with goiters, 379 had diffuse enlargement (56%) while the rest had nodular goiter (44%). Among the sub-population (n= 4897) who underwent thyroid function testing, 9% of those with normal thyroid function tests have goiters.
CONCLUSION: The prevalence of thyroid function abnormalities in the Philippines is 8.53% with the greatest proportion of volunteers having subclinical thyroid disease. There is a low prevalence of both true or overt hyperthyroidism and hypothyroidism. In the larger survey, it was found that 8.9% of volunteers who were examined had goiters. The etiology of these goiters will need to be ascertained in future studies.

Objective: This study aims to determine the prevalence of metabolic syndrome and its individual components across different BMI categories among patients seen at Wellness Center and Obesity and Weight Management Center, St. Luke’s Medical Center Quezon City. Methodology: This was a 3-year retrospective study of patients seen at the institution from 2013 to 2016. The patients were divided according to Asia-Pacific BMI categories and presence of metabolic syndrome was determined as defined by NCEP/ATP III-AHA/NHLBI (2005). Results: This study included a total of 1367 adult patients with the mean age of 53 (SD= 12.4). The overall prevalence of metabolic syndrome is 51.0%. Its prevalence across the different BMI categories are as follows: 29.6 % with Normal BMI (BMI 18.5-22.9 kg/m2), 38.9% in overweight (BMI 23-24.9 kg/m2), 56.9% in Pre-Obese (BMI 25-29.9 kg/m2) and 62.4% in Obese (BMI ≥30 kg/m2) subgroup. Presence of central obesity using the Asian cut-off has the highest prevalence among patients with metabolic syndrome across all categories. In the group with normal BMI, hypertension and elevated blood glucose were highest with central obesity being the least common but still with 7.3% of individuals meeting the criteria for central obesity. Conclusion There is high prevalence of metabolic syndrome even in patients with normal BMI. Diagnosis and screening for its individual components should not only be confined to individuals with higher BMI.
