Objectives:
To compare Predictive Index for Osteoporosis (PIO) with Osteoporosis Self-Assessment Tool for Asians (OSTA) as a clinical tool for identifying the risk of osteoporosis in Filipino men 50e69 and Filipino women 50e65 years of age.
Methods:
This was an analytic study that employed a cross sectional approach that included Filipino men and women seen at the Outpatient Charity Department or at the private clinics and who underwent dual energy X-ray absorptiometry. All subjects completed a structured questionnaire and their weight and height were obtained, from which their PIO and OSTA scores were computed.
Results:
A total of 81 patients were included in the study. OSTA has an area under the curve of 0.712 which turns out to be significant (P ¼ 0.0004), with a calculated likelihood ratio of 1.64. The receiver operating characteristic (ROC) curve of PIO showed that the optimal cut off is > 0.962 and the calculated likelihood ratio that this patient may have osteoporosis is 1.38. Comparing the sensitivity and specificity, the resulting P value of 0.2728 denotes that the area under the curve of the 2 tools is not significantly different.
Conclusions
The optimal cut-off point of OSTA and PIO to discriminate high-risk and low-risk patients for osteoporosis were 0.712 and 0.686, respectively, based on ROC analysis. The performance measures of OSTA and PIO did not vary significantly in predicting the risk for osteoporosis in Filipino adults.

The cell origin, histopathologic features, and prognosis of medullary and papillary thyroid carcinoma are different and to have them occur simultaneously in a single patient is a rare occurrence. This is a case of a 38-year-old female who presented with an enlarging anterior neck mass whose fine needle aspiration biopsy could not rule out a papillary lesion. Thus, she was advised to undergo total thyroidectomy, and her final histopath showed a simultaneous medullary and papillary thyroid carcinoma. Her initial serum calcitonin was elevated at 252 pg/ ml, and it remained persistently elevated over the course of 7 months. A repeat ultrasound revealed solid nodules with coarse calcifications and enlarged lymph nodes at both submandibular regions. This warranted a repeat surgery with neck dissection with the finding of eight lymph nodes positive for metastatic carcinoma. On follow up after her second surgery, the calcitonin decreased to 42.70 pg/ml. Knowledge of this simultaneous occurrence of medullary thyroid carcinoma and papillary cancer is important for its prognostic implications and therapeutic plan

Introduction:
Peripheral Artery Disease (PAD) is a significant marker of cardiovascular disease and is prevalent but underdiagnosed. Ankle-Brachial Index (ABI) is the recommended screening test for PAD. However, not all clinics have a Doppler ultrasound. ABI by palpation offers a more feasible alternative.
Objective:
This study aims to determine the validity of ABI measurement by palpation method in the screening of PAD.
Methodology:
This prospective validation study utilized a cross-sectional analytic design. Three physicians performed the ABI by palpation method and their result was compared to the Doppler ABI. The accuracy indices for validation was computed per physician conducting the ABI by palpation and also as an average of all 3 palpation method readings. During the course of sampling, there were no patients with severe PAD found during the prospective period.
Results:
The accuracy of Ankle Brachial Index using Palpation method yielded the following ranges, sensitivity between 63.16 % - 73.68%, specificity of 94.06% - 98.02%, PPV within 85.37% - 95.45%, and NPV within 80.73% - 86.84% in predicting PAD. The accuracy indices were clinically acceptable. Meanwhile, the raters’ usage of Ankle Brachial Index using Palpation method demonstrated a substantial agreement with ABI by Doppler Method performed by the angiologist (Cohen Kappa >0.60).
Conclusion
The ABI by palpation is a good screening tool for PAD, but the person performing it must be adequately trained to do the procedure. The procedure is affordable and convenient, and should be done routinely during clinic visits in the physical examination of patients with known risk factors for PAD.
