BACKGROUND: In the Philippines, screening for ear problems especially in children at entry to school is usually undertaken by school nurses and teachers who typically do not have specialized instrumentation. The penlight has recently been employed as screening method in determing the possibilities of ear problems in public school communities. This study attempts to determine the accuracy of the penlight as an alternative method for screening to assess the common external ear abnormalities among Grade 1 students in an elementary school. OBJECTIVES: 1. To compare the result of otologic examination using the penlight versus otoscopy in determining of common pediatric ear problems. 2. To determine the sensitivity, specificity and predictive values of penlight examination in the screening of ear canal and tympanic membrane for abnormal conditions among Grade 1 students. METHODS: Otologic examination with the use of a penlight was carried out by the tranined nurse in ears of Grade 1 students and the results compared with those obtained from otoscopy done by an otolaryngologist. Presence of ear conditions such as cerumen, discharge, foreign body, tympanic membrane visualization, and an overall assessment were recorded in an Excel file. The examiners were both blinded with the findings. RESULTS: Ninety-four students (188 test ears) with a median age of 6 years, ranging from 5 to 10 years, and a 1:1 sex distribution were included in the study. The result showed an excellent agreement (P<.001) between the penlight and otoscopic examination. The sensitivity and specificity were of 98.6% and 100%, respectively. The PPV is nearly 100% and NPV of 95.2% and and overall accuracy of 98.94%. CONCLUSIONS There is an excellent agreement between the nurse‘s findings and otolaryngologist‘s findings in examining the ear canal and tympanic membrane. The penlight has on overall accuracy of 98.94%, in identifying cerumen, discharge, foreign body and visualizing the tympanic membrane. Thus, this study shows that with trained nurse in otologic examination, the penlight is an effective screening in identifying common ear problem among children.

BRAF V600E is a possible biomarker for risk stratification and prognostication in papillary thyroid carcinoma. Studies on its association with aggressive clinicopathological features among East Asian populations are limited. This study examines the clinical and histopathological features of this mutation in Filipinos with conventional papillary thyroid carcinoma. Methods: Formalin-fixed, paraffin embedded thyroid tissue blocks of papillary carcinoma for the study period January 2010 to December 2012 were retrieved. Slides were reviewed and described according to tumour size, variant type, sclerosis, multifocality, subcapsular location, extra-thyroidal extension, nodal metastasis, and nodal extracapsular spread. Medical records were reviewed for patient demographics and characteristics. Mutation status was determined using realtime polymerase chain reaction and sequencing. Results: Sixty-five patients were included in this study. BRAF V600E mutation prevalence was 38.46%. The mutation positive group was predominantly female, young (mean age 36 years), with tumour size less than 4 cm, and late-stage disease. Extra-thyroidal extension (60%), significant sclerosis (96%), and subcapsular tumour location (72%) were the most frequent findings. Eighty-three percent of patients with nodal metastasis had extracapsular spread. Conclusions: Compared to some Asian populations, this study of Filipino patients shows a lower prevalence of BRAF V600E mutation. The clinical and histopathological features of mutation positive patients raise important issues regarding extent of surgical excision and appropriate management of neck metastasis for this group.

BACKGROUND: Healthcare access and usage may vary according to socioeconomic class (SEC). Knowing this variable's effect on patient attitudes, practices, and health seeking behavior allows better understanding of compliance, adherence to treatment, and educational needs on allergic rhinitis (AR). OBJECTIVE: This study seeks to assess the attitudes and practices on AR of Filipinos in the National Capital Region. METHODS: A cross sectional survey of 301 Filipinos, stratified into socioeconomic groups ABC1, C2, and DE, was conducted from December 2014 to February 2015. A previously validated and pilot tested questionnaire on AR was administered via structured face to face interviews. RESULTS: Most respondents attributed their symptoms to "colds" (ABC1 77%, C2 79%, DE 78%); most did not consult a physician for their symptoms. Only 26% of all respondents were aware of AR. Only the ABC1 group had respondents who specifically used the term AR. Most respondents' symptoms fulfilled criteria for moderate to severe disease. Sleep was the activity most affected by AR (62%). For symptom relief, over the counter antihistamine-decongestants were the most preferred drug preparations (ABC1 30%, C2 38%, DE 34%). Groups ABC1 and C2 cited family, television, and Internet as the top primary sources of health information; DE cited family, television, and friends. CONCLUSION: Regardless of SEC, Filipinos are not aware of AR. Lack of awareness and gaps in knowledge can result to an underestimation of the condition, decrease in health seeking behavior, unmet patient needs, and undertreatment of disease.

BACKGROUND: Treatment of allergic rhinitis (AR) consistent with consensus guidelines is reported to result in better patient outcomes. However, physicians may manage patients independently of guidelines. Asian data on physician perspectives regarding AR diagnosis and management is limited. OBJECTIVE: The study objective is to assess attitudes and practices on AR of Filipino specialists and generalists. METHODS: A cross sectional survey of 100 specialists and 100 generalists was conducted from November 2014 to January 2015. A previously validated and pilot tested questionnaire was administered via structured face to face interviews. RESULTS: Specialists reported greater adequate knowledge of AR (specialists, 58%; generalists, 39%) and adherence to guidelines (specialists, 84%; generalists, 54%). Diagnostic tests were not routinely used (specialists, 81%; generalists, 92%). Monotherapy, specifically antihistamines, was preferred for mild AR. For moderate-severe AR, preference for monotherapy versus combination therapy (specialists, 49% vs. 51%; generalists, 44% vs. 56%) was similar. Both groups preferred intranasal corticosteroid spray (INCS) for monotherapy and antileukotrienes, antihistamines, INCS for combination therapy. For adjuvant therapy, specialists (82%) preferred nasal irrigation/douche. Primary consideration for choice of therapy was efficacy. Cost was the perceived reason for patients' noncompliance with treatment. CONCLUSION: Despite differences in awareness of and adherence to guidelines, prescribing patterns on management of mild and moderate-severe AR are similar among Filipino specialists and generalists. This can be attributed to a shared perception of efficacy and cost as drivers for therapeutic choices.

BACKGROUND: There is a large global variation in sensitization patterns to aeroallergens due to differences in climate, urbanization, and lifestyle. Knowledge of the most common inhalant allergens is important for appropriate prevention and management of allergic rhinitis (AR). OBJECTIVE: This study aims to provide data on aeroallergen sensitization patterns and associated comorbid diseases of adult Filipinos with AR. METHODS: Medical records of adult Filipinos seen in an Otolaryngology-Allergy Clinic from January 2011 to 2016 were reviewed. Inclusion criteria used was presence of clinically defined AR and positive skin test to at least one aeroallergen in the test panel. Demographics, comorbid conditions, and results of skin prick test were determined. Standard descriptive statistics were used for analysis. RESULTS: One hundred ninety-one adult patients were included in this study. Mean age was 38.8 years, and majority lived in an urban area (71.2%). Most patients exhibited polysensitization (97.4%). All exhibited sensitization to indoor and 86.9% to outdoor allergens. The most common indoor allergens were Dermatophagoides pteronyssinus (97.4%), Dermatophagoides farinae, (95.8%), cockroach (80.1%), and molds (72.8%). Bermuda (67%), Johnson grass (58.7%), and Acacia (58.2%) were the most common outdoor allergens. Urticaria (18.8%), dermatitis (16.8%), and asthma (11.5%) were the most common associated comorbid disease. Twelve percent of patients had more than one associated comorbid disease. Asthma + urticaria followed by asthma + dermatitis were the most common co-morbid combinations. One patient had three comorbid diseases: asthma + urticaria + rhinosinusitis. CONCLUSION: Compared to earlier studies, aeroallergen sensitization patterns of Filipinos remain unchanged. This study also identifies for the first time, the associated comorbid diseases of AR in this population. Understanding these factors can guide treatment strategies to reduce disease burden.

Objective: To present a case of a double ectopic thyroid gland in a 10-year old boy and discuss the pros and cons of the different management options that were available. Methods: Design: Case Report. Setting: Tertiary Hospital in Metro Manila. Subject: One (1). Results: A 10-year-old boy presented with hoarseness and easy fatigability for 6 years. Rigid endoscopy and CT scan showed an infraglottic mass originating from the anterior tracheal wall causing obstruction. Biopsy revealed thyroid tissue with atypia. Thyroid scintigraphy showed uptake in the submental and midline anterior neck. Thyroid hormone levels were consistent with hypothyroidism. Levothyroxine returned hormone levels to normal and resulted in complete regression of the mass with no symptoms of dyspnea, stridor or bleeding. Conclusion The management of ectopic thyroid presents a challenge as there are no guidelines for optimal treatment. Thyroid hormone insufficiency is a frequent occurrence, and emphasis must be given to its monitoring. Surgery in a critical airway lesion such as this may be reserved for cases where the patient experiences dyspnea and stridor or lack of response to thyroid hormone treatment.

The diagnosis of lymphatic malformations can present problems with diagnosis and treatment. Non-response to a chosen procedure can magnify the initial problems or create new ones. We present such a case.

CASE REPORT

            A 9-year-old boy initially presented with a 3-year history of soft upper eyelid mass with red-violet discoloration after hitting his head on a wooden post. About 2 years before this presentation, progressive enlargement in size of the mass with extension to the left maxillary and left scalp region prompted an ophthalmologic consult, and Magnetic Resonance Imaging (MRI) of the orbit and Magnetic Resonance Angiography (MRA) of intracranial vessels revealed a venous-lymphatic malformation. (Figure 1) He was then referred to our institution for further management.

            The patient was noted to have a 4x2 cm reddish vascular mass over the left eyelid with no thrill or bruit and a surrounding 9x9 cm bluish left facial swelling in the periorbital region extending to the maxillary area corresponding to the MRI images. A repeat MRI/MRA showed a prominent branch of the left external carotid artery coursing towards the mass. (Figure 2)

An angiogram of the neck for possible coil insertion into the prominent vessel from the external carotid artery was performed by interventional radiology. However, the left common carotid, left external carotid, and left vertebral arteries showed no evidence of high- or low-flow arteriovenous malformation. (Figure 3) This favored a hypovascular, space-occupying lesion consistent with a cystic lymphatic malformation and the boy was referred back to our service for possible surgery.

Meanwhile, the mass continuously increased in size and by the time he was seen again in our clinic, the mass measured 15x15x20 cm occupying the left hemifacial area from the midportion of the parietal bone superiorly to the body of the mandible inferiorly, with violaceous skin discoloration and verrucous infraorbital lesions. (Figure 4) The patient was not considered a good candidate for surgical excision due to the size of the mass relative to his body, and initial sclerotherapy was planned to possibly decrease the size of the mass enough for excision of any residuals.

Percutaneous Sclerotherapy was performed using a guidewire-catheter replacement technique. An initial drainage of 800mL of non-clotting serosanguinous fluid was followed by infusion of 3% sodium tertradecyl sulfate, followed by 99% ethanol infusion. There was gross decrease in the size of the mass after the procedure. (Figure 5) A pigtail drainage catheter was maintained to continuously drain fluid from the lesion. On the 10th hospital day, the boy had febrile episodes associated with enlargement of the left hemifacial mass. Blood cultures showed no bacterial growth. Culture of the pigtail catheter tip grew Morganella morganii. Amikacin 170mg IV every 8 hours was started but fever was unrelenting. Wound cultures grew Methicillin Resistant Staphylococcus Aureus, and Co-trimoxazole 40mg/200mg per 5ml Pediatric Suspension, 10ml every 12 hours and Metronidazole 200mg/5mL oral suspension, 5mL every 8 hours were initiated.

During this month-long post-operative period, the mass continued to expand to its preoperative size. (Figure 6) Due to lack of funds, the antibiotics were given by mouth and the patient was discharged. On 3-month follow up, the mass had grown to even larger than the pre-embolization stage.

 DISCUSSION

            Lymphatic malformations (LM) are made up of variously dilated lymphatic channels or cysts, lined by endothelial cells with a lymphatic phenotype.1  Histologically, LM is classified into the macrocystic type, consisting of cysts larger than 2 cm with clear boundaries, and the microcystic type consisting of cysts smaller than 2 cm that appear diffuse and sprouted without clear boundaries. The two types coexist in the combined type.2  

            A 5-stage clinicoradiologic staging system has been devised by de Serres et al. based on cervical LM laterality and relationship to the hyoid bone predicting operative risk and surgical outcome.3 The higher the clinicoradiologic stage, the greater the potential risk of intraoperative and postoperative complications.  In general, bilateral microcystic suprahyoid LMs are more difficult to treat than infrahyoid LMs, especially when there are microcystic LMs involving the oral cavity, tongue, and/or pharynx. In this case, confirming whether it was a high-flow or a low-flow disease presented a dilemma early on. We relied on the initial MRI/MRA findings of a possible arterial feeding vessel, considering that MRI/MRI is more than 90% accurate in the diagnosis of high-flow vascular anomalies.4 However, during angiography for coil insertion, there were no feeding vessels found and a low-flow disease was considered. Thus, there were further delays in management associated with these procedures.

            In our case, the patient had a unilateral suprahyoid LM that has a complication rate of 41% with an average of 1.5 procedures to treat and cure the disease.3 The possible complications that were considered included facial nerve palsy, seroma, exsanguination and most importantly, functional compromise due to the projected large post-operative defect and location of the mass which could affect function of the left eye, feeding problems and long term facial disfigurement.5

            Considering these possible complications, we planned to attempt initial sclerotherapy before considering surgery. However, we encountered infection of the pigtail site and wound, and sclerotherapy failed to decrease the size of the mass. At the moment, subjecting the patient to repeat sclerotherapy may have a higher chance of failure.

            Noting that the treatment of lymphatic malformation should be directed towards preservation of functional and aesthetic integrity,5 we present our case for consideration.
