1.Precision medicine meets AI
Journal of Medicine University of Santo Tomas 2024;8(2):1403-1404
There are rapid advancements in AI-driven diagnostics and wearable technologies, which are enabling early disease prediction, especially in conditions like Parkinson's disease. Precision medicine, underpinned by molecular biology and genomic data, allows clinicians to tailor treatment based on patient phenotypes, significantly enhancing personalized healthcare. AI complements this by processing vast datasets, from health records to biomarker evaluations, supporting more precise diagnostics and treatment recommendations.

Kennedys disease (KD) is a rare, slowly progressive neurodegenerative disorder of motor neurons in the spinal cord and brain stem. Most of the cases of KD in clinical practice are misdiagnosed. The knowledge of the initial presentation, the range of age within which the disease would manifest and the clinical course of the disease would be very helpful to better manage and anticipate the outcome of such cases. This report highlights the typical earliest presentation of KD and the clearcut clinical picture of KD that differentiates it from other motor neuron diseases of grave scenario and prognosis We report clinical details of 4 male patients with KD seen in our center. Diagnosis of these four patients were based on their clinical picture the time they were first seen. Common features in their history and presentation were the onset of prolonged and intermittent muscle cramps followed by weakness and atrophy of the muscles involved. All of them developed gynecomastia. Three of them have concomitant diabetes, and one has thyroid problem. All of them were initially diagnosed as Amyotrophic lateral Sclerosis.

4.Fork in the road: Pick research and publication
Journal of Medicine University of Santo Tomas 2022;6(2):943-
I see clinicians often and when time is kind, a conversation about research ensues. There is always interest but to actually engage in research, many shake their heads and sigh “no time.” I wonder about lost opportunities to learn and study diseases when clinicians are not inclined to or not supported in research.
At every stage of medical education, training, and professional practice whether in academia or in clinic or hospital, physicians inevitably encounter a fork in the road. The paths of clinician and/or academician are large lanes in the highway, yet at a junction, the highway becomes two roads, one to remain as clinician or academicians and the other to pursue research and publication. As well-known, many choose to remain in clinic or in classroom.

7.Viewpoint: Physician as a Clinician, Researcher, and Academician

The daily work life of physicians who function as clinicians, researchers, and academicians is focused on improving public health and patient outcomes in three usually compartmentalized settings: clinics, classrooms, and centers for research. In these settings, physicians are addressing patients’ medical concerns based on evidence, and at the same time, considering if new information could lead to research and discovery for better patient outcomes. The physician then proceeds to mentor, teach, and train medical students in quality evidence-based clinical practice and the conduct of scientific research. The importance of operationally blending these three disciplines with research as a common thread is not only a big challenge for these physicians but also an opportunity to innovate for better public health.

8.A pilot study on the effect of statins, fibrates and its combination in rat nerves.

Philippine Journal of Neurology 2004;8(1):1-5
OBJECTIVE: To determine the histopathological effect of statins, fibrates and its combination in rat nerves
METHODOLOGY: This is a pilot experimental study. Four male albino rats were used in this study. Each rat was given therapeutic doses of simvastatin alone, gemfibrozil alone, gemfibrozil and simvastatin combination and placebo. On day 21, the sciatic nerve was harvested for histopathologic examination
RESULTS: Although not marked, the combination of simvastatin and gemfibrozil produced more axonal degeneration than did simvastatin alone or gemfibrozil alone. Axonal degeneration was documented on teased nerve fibers and epon cross sections
CONCLUSION: The use of lipid lowering agents may induce peripheral neuropathy Recommendation: This pilot study serves as rationale to proceed with an experiment not only to document neuropathy but also correlate the possible association of the pathomechanism of myotoxicity and neurotoxicity of lipid lowering agents.

OBJECTIVE: To determine the prevalence of anxiety and its correlation with the quality of life among cognitively-intact, community dwelling Filipino patients with idiopathic Parkinson disease (PD) seen at the Movement Disorders Clinic of a tertiary hospital.
STUDY DESIGN: Prospective, cross-sectional study.
METHODS: Seventy six (76) Filipino outpatients fulfilling the United Kingdom Parkinson Disease Society Brain Bank Clinical Diagnostic Criteria for PD were included in the study. Demographic data were obtained including: age, sex, onset of disease, disease duration and medication intake. The Mini Mental State Examination (MMSE) was done to exclude significant cognitive impairment. The Hamilton Anxiety scale (HAM-A) was administered to quantify anxiety. The degree of anxiety was correlated with the quality of life instrument, Short form health survey (SF 36); and the functional and motor severity using the Unified Parkinson Disease Rating Scales (UPDRS).
FINDINGS: Our cohort of patients had a mean: age of 61 years (range: 42 - 81 years), and disease duration of 1.3 years (33 months). Out of the 76 patients, 37( 48.6%) probably had significant anxiety symptoms based on the the HAM A. Anxiety greatly impacts scores on SF 36.
CONCLUSION: The prevalence of anxiety among this Filipino cohort of patients is 48.6% which is higher than commonly reported worldwide. The presence of anxiety significantly correlated with poorer quality of life.
