A Visit to Microtel Inn & Suites in Palawan

By Jeffrey V. de Guzman

I just recently attended a seminar/workshop on Integrity Development Plan of Action which was held at the Microtel Inn & Suites in Puerto Princesa City, Palawan.  If you are planning for a short vacation or extended stay to rest from your stressful work in the city, the place can be an option.

Refresher Course First Batch Socials at Harbor Square


Refresher Course on Malaria Microscopy for Medical Technologists

The Malaria Control Program (MCP) of the National Center for Disease Prevention and Control, Department of Health in collaboration with Center for Health Development 3 through the support of Global Fund Consolidated Malaria Project conduct Refresher Course on Malaria Microscopy for Medical Technologists from Global Fund Provinces expansion sites to further enhance their knowledge, skills, and capabilities in diagnosing malaria. A refresher course will be conducted on a regular basis every after three (3) or five (5) years.

The training course was divided into three (3) batches with at least thirteen (13) participants each. It was held at the Orchid Garden Suites, Manila on June 28 – July 2, 2010 for the first batch; July 5 – 9, 2010 for the second batch; and July 12 – 16 for the third batch.

The course objective to equip participants with knowledge and skills on malaria microscopy were satisfactorily achieved through lecture discussions, actual demonstrations, and microscopy sessions using bench microscopes with topics on the morphology of human malaria, basic laboratory techniques, the new drug policy, care and maintenance of microscope, parasite quantification, quality assurance, and PHILMIS.

All participants were able to finish the course with satisfactory grades. A comparison of the general average of the class in the pre and post tests showed a significant increase in the theoretical and practical examinations.

Evaluation of the course by the participants resulted to a very high overall rating. Participants expressed their satisfaction in the training materials, coverage of the course, venue, facilitators, and the general atmosphere in the conduct of the training.

Workable Recording and Documentation System for Microscope Preventive Maintenance

It has been said, “work not recorded is work not done”. Therefore, such job must have a corresponding job request / report. Preventive maintenance report indicating among other things such as, the nature of work done, parts used, date of repair / PM, and other important and useful information are usually found.

Equipment Record
Records shall be maintained which include the
 Name of equipment
 Manufacturer’s name, serial number or other unique identification
 Date received and placed in service
 Condition when received (new, used)
 Records of calibration, date of next calibration
 Details of maintenance carried out
 Current location, where appropriate
 Copy of manufacturer’s operating instructions, where available
History of damage, malfunction or repair

Routine Inspection
 Ocular check of the physical surface
 Checking electrical plugs, sockets, cables, bulbs
 Check screws and other mechanical parts
 Check optical elements from mechanical damage and dirt
Check illumination by plugging it to electric power source

Performance Check
 Run the field stop diaphragm throughout its full range
 Move all the blades of iris by its lever control
 Run the condenser height adjustment full range; check its centering screw if it moves the condenser smoothly.
 Check the mechanical stage if it can move the specimen smoothly and without play throughout its full range. Check by observing at the microscope’s highest magnification.
Parameter: 1 micron stage movement observed at 1000X magnification looks like 1 mm viewed without a microscope and at a distance of 250 mm.
 Objectives mounting shoulder, nosepiece must be absolutely clean. If not, centering and focusing are lost.
 Rotate nosepiece through 360ยบ and observe all clicking stop positions from either side without any play
 Run the fine and coarse adjustment knobs throughout their full range of adjustment.
 Make sure that the upper surface of the stand and the corresponding mounting surfaces of the observation tube must be cleaned & free of corrosion.
 Adjustment of interpupillary distance of the tube must run smoothly and without exerting undue force.
 All optical surfaces must be absolutely cleaned. Pay special attention to: light bulb, cover glass on field stop, condenser front lens, objective front lens, upper surface of eye lens. Inspect and clean accordingly.

Microscope Bulb Installation & Replacement

• Setting the line voltage selector switch in position
Ascertain that the line voltage selector switch (1) is set in conformity with the local line voltage. If not, the switch should be set at 100V (110~120V) or 200V (220~240V) correctly by means of a screw driver.


1. Turn the microscope on its side and pull the lamp housing knob (1) to open the lamp housing cover (2)
2. Install the bulb.
• 6V, 20W halogen bulb
Hold the halogen bulb contained in a polyethylene bag to avoid leaning finger prints on the bulb and insert the contact pins into the bulb socket all the way (3).

• 110V/120V 30W tungsten bulb
Insert the tungsten bulb with its mirror portion (4) located at the lower side into the bulb socket; (3) then, pressing it against the socket, rotate the bulb clockwise.

– Before use, wipe off fingerprints or soils on the bulb.
– 110 V bulb for local line voltage 120V or higher.
– After bulb installation, close the lamp housing cover (2) , pushing in the cover knob (1) .
– If the bulb burns out during observation, be certain to cool the defective bulb completely before replacement.
Tungsten Bulb
• Pull power plug
– Place microscope on its side so that rack and knob of the mechanical stage are facing up
• Loosen clamping screw
– Remove lamp socket from spring clamp. Unscrew burnt-out lamp from the socket, and insert new 6V, 5W filament lamp. Wipe off any fingerprints on the lamp bulb.

• To insert new lamp, put lamp socket into spring clamp, turning and shifting it until lamp coil and its mirror image are opposite each other when observing lamp and concave mirror. Insert lamp holder with filament lamp in receptacle so that screw fits into slot. Tighten clamping screw
