BACKGROUND

Medication compliance contributes to preventing significant morbidities, such as stroke, among hypertensive patients.

OBJECTIVE

This study aimed to examine the factors affecting hypertensive patients' medication compliance in Sambag II, Cebu City.

METHODS

This study is an observational cross-sectional study. The study was conducted in Barangay Sambag II of Cebu City and involved 170 random, voluntary, self-reporting hypertensive patients. The Tao Yamane formula was used to determine the sample size. An interviewer-guided survey questionnaire was utilized to collect the data for the pilot study. The data were analyzed using Cronbach’s Alpha Test for internal consistency and reliability.

RESULTS

Three factors were shown to influence compliance with antihypertensive medications. These are the source of medication, access to medication, and symptoms experienced before intake of anti-hypertensive medications. A factor that significantly affects compliance is the source of medication, wherein hypertensive patients prefer medications from retail pharmacies compared to the free medications supplied by the local health center.

CONCLUSION

Residents of Sambag II, Cebu City preferred medications from retail pharmacies over the free medications provided by the local health center. Local health units may use this information to implement information drugs regarding the efficacy of medications provided by government agencies. Further studies are recommended to use subgroup analysis on factors influencing compliance and non-compliance to anti-hypertensive medicines.

Objectives: To determine the overall diagnostic yield of bronchoscopy-guided sampling methods in detecting lung cancer at the University of the Philippines, Philippine General Hospital. The diagnostic yield, equivalent to sensitivity, is defined as the number of bronchoscopic sampling or biopsy procedures with a diagnosis of malignancy divided by the total number of confirmed malignant cases. Methods: This is a cross-sectional, retrospective sensitivity study involving bronchoscopy procedures from January 2014 to December 2018. Surgical Pathology and Cytology Reports of eligible cases were accessed through the institutional Laboratory Information System. Sensitive patient information was omitted, and each case was assigned a unique code. The overall diagnostic yield/sensitivity of bronchoscopy and the diagnostic yield/sensitivity of each technique were calculated. Results: A total of 100 patients satisfied the inclusion and exclusion criteria. Primary lung malignancies are more common in males and the elderly. The most common primary lung cancer is adenocarcinoma (33%). Bronchoscopy, regardless of whether single or multiple techniques were used, has a diagnostic yield of 86% (CI: 77.6-92.1%). Of the individual techniques, those that obtain solid tissues (endobronchial and transbronchial biopsies; 88.2% [CI: 78.1-94.8%] and 80.0% [CI: 28.4-99.5%], respectively) have higher yields compared to techniques that obtain cytologic samples (bronchial washing and brushing; 54.2% [43.7-64.4%] and 70.1% [58.6-80%], respectively). Conclusion Bronchoscopy, as a diagnostic procedure for pulmonary malignancies, has relatively high sensitivity and may be used for lesions located centrally and can be inspected visually. A multidisciplinary approach to patient selection for bronchoscopy helps improve the utility of the various bronchoscopic techniques.

This is the case of a 37-year-old female patient presenting with a 10-year history of a gradually enlarging right infra-auricular mass. A parotidectomy was performed. The surgical pathology specimen consisted of an 18 cm diameter encapsulated nodular mass with a homogenous, cream-tan solid surface. Microscopic section showed an encapsulated neoplasm with abundant chondromyxoid stroma and tubular epithelial elements characteristic of a pleomorphic adenoma. (Figure 1) Randomly scattered within the tumor were foci of haphazard and complex glands. (Figure 2) These glands exhibited nuclear pleomorphism, luminal necrosis, and mitoses compatible with an adenocarcinomatous proliferation. (Figure 3) Based on these features, the case was signed out as an intracapsular carcinoma ex pleomorphic adenoma.

Carcinoma ex pleomorphic adenoma is a carcinoma arising from a pre-existing pleomorphic adenoma. The antecedent benign tumor may either be a long-standing one, often with a history measured in decades, or characterized by a protracted history of excisions and multiple recurrences.1,2 The carcinoma on the other hand is either epithelial or myoepithelial in derivation. By morphologic sub-type, the most commonly reported carcinoma arising in a pleomorphic adenoma is a salivary duct carcinoma or an adenocarcinoma that is not otherwise specified (NOS).1,3 Residual pleomorphic adenoma tissue is identifiable either in its typical morphology, a chondromyxoid stroma, or a hyalinized sclerotic nodule.1

Aside from the type of carcinoma arising from the pleomorphic adenoma, another parameter that has to be reported is the extent of involvement by the carcinomatous component. A carcinoma that is entirely limited to within the parent tumor that is still enclosed by a complete capsule is termed an "intracapsular" or "non-invasive" carcinoma ex pleomorphic adenoma.1,2 Once the carcinoma breaches the capsule and infiltrates the surrounding tissue, then it is considered invasive. If the invasion is less than 4 - 6 mm beyond the capsular border, the tumor is termed "minimally invasive". Carcinomatous elements that extend beyond this threshold is termed "widely invasive".1 This threshold is greater than the previous threshold of 1.5 mm recommended in an earlier edition of the WHO classification although the present edition does state that this threshold is preliminary and requires further validation.1,2,4 It has to be pointed out though that quantifying invasion may not always be possible in tumors that have positive margins, those that are intrinsically unencapsulated such as minor salivary gland tumors, and those with complex multinodular growth patterns such as in recurrent pleomorphic adenoma.1 This difficulty has to be stated in the report and what conditions preclude quantifying the degree of invasion.

Non-invasive carcinoma ex pleomorphic adenoma has quite a good outcome with very low reported rates of recurrence or regional metastasis. In a review of thirty cases and a report of an additional three cases, only one case showed recurrence or metastasis.3 This favorable outcome certainly contrasts with that of the widely invasive type where metastasis is reported to occur in up to 70% of cases.1 Another review of ten cases showed one case developing metastasis, and recommended that non-invasive cases should thus still be followed up closely after primary treatment because regional or distant metastasis can occur.2

To the best of our knowledge, there are no published local data on the incidence of early malignant transformation of pleomorphic adenomas in the Filipino population. Hence, we take this opportunity to report this case. Awareness of the entity and prudent liberal sampling of these tumors may help address this gap.
