INTRODUCTION:Radioactive iodine(I131) therapy is an established definitive treatment for Graves' hyperthyroidism.However,the optimal method of determining the radioiodine treatment dose remains controversial.
OBJECTIVE: To compare the efficacy of fixed dose versus  calculated  dose  regimen  in  the  treatment  of  Graves'  hyperthyroidism  among  Filipinos 
METHODOLOGY: Diagnosed   Graves'   disease   patients underwent  thyroid  ultrasound  to  estimate  thyroid  size. Patients  were  randomized  to  either  fixed  or  calculated dose  of  radioiodine  treatment.  For  fixed  dose  group,the  WHO  goiter  grading  was  utilized:  Grade   0   (5mCi),  Grade   1  (7mCi),  Grade2  (10mCi),  Grade  3  (15mCi).  For calculated  dose  group  the  following  formula  was  used:
                    Dose(mCi)= 160uCi/g thyroid x thyroid gland weight in grams x 100  /  24-hour RAIU(%)
Thyroid function test (TSH,FT4)  was monitored every  three  months  for  one  year. 
RESULTS: Of  the  60  patients  enrolled,  45  (fixed  dose;  n= 27,  calculated  dose;  n=  18)  completed  the  six  months follow-up  study.  Analysis  was  done  by  application  of  the  intention-to-treat  principle.  The  percentage  failure  rate  at  third  month  in  the  fixed  vs.  calculated  dose  group  was:  26  v.  28%  with  a  relative  risk  (RR)  value  of  0.93.  At  six  months  post-therapy,  there  was  a  noted  reduction  in  the  failure  rates  for  both  study  groups  (11  vs.  22%,  respectively),  with   a   further   reduction   in   the   relative   risk   value (0.67),  favoring  the  fixed  dose  group.
CONCLUSION: Fixed   dose   radioiodine   therapy   for Graves'   disease   is   observed   to   have   a   lower   risk   of   treatment   failure   (persistent   hyperthyroidism)   at   three  and  six  months  post-therapy  compared  to  the calculated  dose.

Anterior cruciate ligament (ACL) injury remains a common orthopedic case, especially in young adults with an active lifestyle. Activities of daily living and sports performance may be vastly compromised; thus, immediate diagnosis is essential. The researchers tested the diagnostic ability of the anterior tibial translocation sign (using the 5 mm cut-off) against the gold standard knee arthroscopy using cross-sectional study design. Analysis of the 23 magnetic resonance imaging (MRI) scans showed a sensitivity of 42.9% (true positives: 6 had ≥5 mm reading out of 14 positive arthroscopy fi ndings), specifi city of 77.8% (true negatives: 7 had <5 mm reading out of 9 negative arthroscopy fi ndings) and positive predictive value (PPV) of 75.0% (6 out of 8 positive arthroscopy fi ndings among ≥5 mm). In the sample data, 7 mm cut-off had the optimal trade-off between sensitivity and type I error, thus being the most predictive of ACL tear.

INTRODUCTION: Pre-impaired  glucose  tolerance  (pre-IGT) or  compensated  hyperinsulinemia,  is  defined  as  normal glucose,  and  elevated  insulin  two  hours  after  a  75-gram oral glucose load.  It is characteristic of the early stages of diabetes  mellitus  (DM),  where  beta  cells  compensate  for  insulin resistance by increasing insulin secretion to maintain normoglycemia. With  continuing  beta  cell  failure,  insulin  secretion  eventually  fails,  leading  to  the  progression  to diabetes.    Nonalcoholic  fatty  liver  disease  (NAFLD),  a common feature of insulin resistance, is found in 50-75% and 42-55% of DM and pre-diabetes patients. We determined if
NAFLD was present in patients with pre-IGT.
METHOD: A study on the determination of NAFLD - diagnosed by liver ultrasound in pre-IGT patients at a university hospital.Descriptive statistics, Chi square test of independence, 2x2 Fischer  Exact  test,  Z  test  of  difference  in  proportion, were used  for  statistical  analysis  with  a  p-value  set  at  0.05?.IBMSPSS ver 21 was used as software.
RESULTS:The mean age of 22 patients was 29.95 years, with average BMI of 25.73 kg/m2;77.3% were female.  Average lipid  panels  were  within  optimal  limits;  kidney  and  liver functions were normal.  The mean insulin level was 58.36 uIU/mL. NAFLD was identified in eight of the subjects.
CONCLUSION: Although  pre-IGT  is  a  subclinical  phase  in  the  diabetes  spectrum,  36%  already  have  NAFLD.This prevalence  was  lower  compared  to  diabetics  and  pre-diabetics, but higher compared to the general population.There was a noticeable trend of increasing insulin levels with increasing severity of fatty liver.
