Tuberculosis is a global disease with a high prevalence rate in the Philippines. Frank hemoptysis often occurs later in the disease and is usually not massive since the availability of anti-Koch’s treatment. However, Rasmussen’s aneurysm, a pulmonary vascular complication secondary to tuberculosis from the weakening of the pulmonary arterial wall adjacent or within a tuberculous cavity, can be an uncommon cause of massive and potentially fatal hemoptysis.

A 35-year-old male patient presented with episodes of hemoptysis while being treated for pulmonary tuberculosis for two weeks. An episode of massive hemoptysis of ~400ml prompted his admission. Chest tomography with contrast showed bronchiectatic changes, cavitary formation, and an aneurysmal dilatation of the anterior segmental artery of the left upper lobe. He was diagnosed with Rasmussen’s aneurysm. A multidisciplinary team consisting of pulmonologists, interventional radiologists and thoracic surgeons planned for a surgical intervention as coil embolization was deemed to be difficult due to the wide neck character of the aneurysm. On re-admission after patient optimization, repeat chest tomography showed interval regression of pulmonary cavity with thrombosis of the previously identified Rasmussen’s aneurysm. Patient completed his 6-month antitubercular treatment with no further episodes of hemoptysis.

In patients with tuberculosis, hemoptysis results from involvement of the parenchyma, bronchiectasis, or erosion of residual cavities. Hemoptysis from the rupture of a dilated vessel such as Rasmussen’s aneurysm is a rare cause. Chest tomography with contrast is the imaging modality of choice as it demonstrates the focal pulmonary artery dilatation. Embolization or surgical lobectomy are typically utilized to control the bleeding. However, treatment with anti-tuberculous regimen may result already in regression and eventual thrombosis of the aneurysm. Watchful monitoring is imperative as massive hemoptysis may recur; radiologists and surgeons must be available at any time in case intervention is required.

Background and Objectives: Mechanical ventilators are essential albeit expensive equipment to support critically ill patients who have gone into respiratory failure. Adequate numbers should always be available to ensure that a hospital provides the optimal care to patients but the number of patients requiring them at any one time is unpredictable. Finding therefore the best balance in providing adequate ventilator numbers while ensuring the financial sustainability of a hospital is important. Methods: A quantitative method using Monte Carlo Simulation was used to identify the optimal strategy for acquiring ventilators in a large private tertiary medical center in Metro Manila. The number of ventilators needed to provide ventilator needs 90% of the days per month (27/30) was determined using historical data on ventilator use over a period of four years. Four acquisition strategies were investigated: three ownership strategies (outright purchase, installment, and staggered purchase) and a rental strategy. Return on Investment (ROI), Internal Rate of Return (IRR), Modified Internal Rate of Return (MIRR), Net Present Value (NPV), and Payback period (or Breakeven Point) for each strategy were determined to help recommend the best strategy. A qualitative survey was also conducted among doctors, nurses, and respiratory therapists who were taking care of patients hooked to ventilators to find out their experiences comparing hospital-owned and rental ventilators. Results: It was found that a total of 11 respirators were needed by the hospital to ensure that enough respirators were available for its patients at least 90% of the days in any month based on the previous four-year period. This meant acquiring three more ventilators as the hospital already owned eight. Among the strategies studied, projected over a 10-year period, the installment strategy (50% down payment with 0% interest over a 5-year period) proved to be the most financially advantageous with ROI = 9.36 times, IRR = 97% per year, MIRR = 26% per year, NPV = ₱39,324,297.60 and Payback period = 1.03 years). A more realistic installment strategy with 15% (paid quarterly or annually) and 25% annual interest rates were also explored with their financial parameters quite like but not as good as the 0% interest. The outright purchase of three ventilators came in lower (ROI = 4.53 times, IRR = 55% per year, MIRR = 19% per year, NPV = ₱38,064,297.60 and Payback period = 1.81 years) followed last by staggered purchase with ROI = 3.56 times, IRR = 64% per year, MIRR = 28% per year, NPV = ₱29,905,438.08, and payback period of 2.06 years. As there was no investment needed for the rental strategy, the only financial parameter available for it is the NPV which came out as ₱21,234,057.60. The qualitative part of the study showed that most of the healthcare workers involved in the care of patients attached to the ventilator were aware of the rental ventilators. The rental ventilators were generally described as of lower functionality and can more easily break down. The respondents almost uniformly expressed a preference for the hospital-owned ventilators. Conclusion This analysis showed that the best ventilator ownership strategy from a purely financial perspective for this hospital is by installment with a 50% down payment and 0% interest. Moderate rates of 15% and 25% interest per year were also good. These were followed by outright purchase and lastly by staggered purchase. The rental strategy gave the lowest cumulative 10-year income compared to any of the ownership strategies, but may still be considered good income because the hospital did not make any investment. However, it seems that most of the healthcare workers involved in taking care of patients on ventilators thought the rental ventilators were of lower quality and preferred the hospital-owned ventilators.

Myeloid sarcoma, characterized by the presence of immature myeloid cells occurring at an extramedullary site, is a rare manifestation of acute myelogenous leukemia (AML). Spinal cord compression as an initial presentation of AML is very rare with only a few reported cases. We discuss a case of a 22-year-old male who presented with bicytopenia and paraplegia. Workups were consistent with AML with monocytic differentiation. Chromosomal analysis revealed loss of Y and t (8;21). Spinal cord MRI showed intradural extramedullary-enhancing soft tissue lesions at levels T2 to T7 and L5 to S1, suspected to be myeloid sarcoma. Patient, however, succumbed to severe nosocomial infection prior to initiation of chemotherapy and radiotherapy.

BACKGROUND

The University of the Philippines College of Medicine has been lauded for its research output, especially among faculty members. Research is also integrated in its curriculum for medical students in pursuit of “six-star physicians.” However, there has been no consolidated analysis on the outcomes of feedback collected from students.

OBJECTIVES

The study aims to describe the perception of research education among medical students in Learning Units III to VII (LU III-VII) from academic year 2017-2018 to 2019-2020 in the University of the Philippines College of Medicine (UPCM).

METHODS

Through a mixed-method descriptive design, students enrolled in the MD and MD-PHD program from LU III-VII of the UPCM were invited to participate in a survey. Furthermore, a review of the student research database and course evaluations were conducted.

RESULTS

A total of 197 student-initiated studies were conducted according to the college database, varying in types and approaches. However, only 4% of the registered research was published. Research-oriented courses were also rated highly among the medical students. This was consistent with positive attitudes towards research among the majority of participants. However, only 32.2% of the target sample size participated in the survey.

CONCLUSION

Participants of the survey had positive perceptions regarding their research education. However, there are several areas for improvement such as provision of grants, publication assistance, compliance with research registration, and mentorship in data analysis.
