Well-Differentiated Thyroid Cancer: The Philippine General Hospital Experience.

BACKGROUND: Well-differentiated thyroid cancer (WDTC) is the most common form of thyroid malignancy. While it is typically associated with good prognosis, it may exhibit higher recurrence and mortality rates in selected groups, particularly Filipinos. This paper aims to describe the experience of a Philippine Hospital in managing patients with differentiated thyroid cancer. METHODS: We performed a retrospective cohort study of 723 patients with WDTC (649 papillary and 79 follicular), evaluating the clinicopathologic profiles, ultrasound features, management received, tumor recurrence, and eventual outcome over a mean follow-up period of 5 years. RESULTS: The mean age at diagnosis was 44±13 years (range, 18 to 82), with a majority of cases occurring in the younger age group (<45 years). Most tumors were between 2 and 4 cm in size. The majority of papillary thyroid cancers (PTCs, 63.2%) and follicular thyroid cancers (FTCs, 54.4%) initially presented as stage 1, with a greater proportion of FTC cases (12.7% vs. 3.7%) presenting with distant metastases. Nodal metastases at presentation were more frequent among patients with PTC (29.9% vs. 7.6%). A majority of cases were treated by complete thyroidectomy, followed by radioactive iodine therapy and thyroid stimulating hormone suppression, resulting in a disease-free state. Excluding patients with distant metastases at presentation, the recurrence rates for papillary and FTC were 30.1% and 18.8%, respectively. CONCLUSION: Overall, PTC among Filipinos was associated with a more aggressive and recurrent behavior. FTC among Filipinos appeared to behave similarly with other racial groups.

Validation of the oral health screening questionnaire in predicting serious periodontitis among adult Filipinos with type 2 diabetes mellitus / Journal of the ASEAN Federation of Endocrine Societies

@#<p style="text-align: justify;"><strong>BACKGROUND:</strong> Periodontitis affects more than half of patients with diabetes. In resource poor areas in the Philippines, access to routine dental visits may be difficult and thus, a selective approach might be needed to identify those who need dental evaluation and management. An easy-to-administer oral health self-report questionnaire was developed in order to predict serious (moderate to severe) periodontitis.<br /><strong>OBJECTIVE:</strong> The study aims to determine the validity of the Oral Health Screening Questionnaire for Persons with Diabetes (OHSQPD) in estimating the prevalence of serious periodontitis.<br /><strong>METHODOLOGY:</strong> A cross-sectional criterion-referenced study of 175 participants with T2DM were included in the study. They were asked to answer the questionnaire and then made to undergo a full dental examination to identify the presence and severity of periodontitis. The validity of the questionnaire was assessed by determining the sensitivity, specificity, positive predictive value, negative predictive value and area under the receiver-operating curve (AUROC) with the dental examination as the gold standard.<br /><strong>RESULTS:</strong> Using the questionnaire, the prevalence of serious periodontitis was 61% (106) based on an optimal cut-off score of ?12. At this score, the questionnaire yielded a sensitivity of 80.4% and a specificity of 70.6%, with an AUROC of 0.83.<br /><strong>CONCLUSION:</strong> The OHSQPD is a valid tool in detecting serious periodontitis</p>

Risk Factors for Recurrence in Filipinos with Well-Differentiated Thyroid Cancer.

BACKGROUND: The incidence of well-differentiated thyroid cancer (WDTC) has increased in recent years. Despite its excellent prognosis, increasing morbidity from recurrent diseases continues to affect long-term outcomes. Among at-risk populations, Filipinos have the highest incidence of thyroid cancer worldwide, characterized by a highly aggressive and recurrent form of disease. Here, we sought to identify risk factors associated with disease recurrence among Filipinos with WDTC. METHODS: This retrospective cohort study examined 723 patients diagnosed with WDTC seen at Philippine General Hospital. Affected individuals were classified based on the presence or absence of disease recurrence. Multivariate logistic regression analyses were used to determine significant predictors of recurrence. RESULTS: Multiple risk factors, including age >45 years (odds ratio [OR], 1.44), multifocality of cancer (OR, 1.43), nodal involvement (OR, 4.0), and distant metastases at presentation (OR, 2.78), were significantly associated with a recurrence of papillary thyroid cancer (PTC). In contrast, follicular variant histology (OR, 0.60) and postsurgical radioactive iodine therapy (OR, 0.31) were protective for PTC recurrence. Distant metastases at presentation (OR, 19.4) and postsurgical radioactive iodine therapy (OR, 0.41) were associated with follicular thyroid cancer (FTC) recurrence. CONCLUSION: Lymph node metastases at presentation was the strongest predictor of recurrence in PTC, whereas distant metastases at presentation was the strongest for FTC recurrence. Among Filipinos, stratification of WDTC patients based on recurrence risk factors identified in this study will be helpful in guiding the intensity of treatment strategies and long-term thyroid cancer surveillance.

Anaplastic Thyroid Cancer: Experience of the Philippine General Hospital.

BACKGROUND: Anaplastic thyroid cancer (ATC) is a rare type of thyroid malignancy and one of the most aggressive solid tumors, responsible for between 14% and 50% of the total annual mortality associated with thyroid cancer. METHODS: A retrospective study was made of all ATC cases diagnosed by biopsy in the Philippine General Hospital between 2008 and 2013. RESULTS: A total of 15 patients were identified, with a median age at diagnosis of 63 years. All tumors were at least 6 cm in size upon diagnosis. All patients had a previous history of thyroid pathology, presenting with an average duration of 11 years. Eleven patients presented with cervical lymphadenopathies, whereas seven exhibited signs of distant metastases, for which the lungs appeared to be the most common site. More than 70% of the patients presented with a rapidly growing neck mass, leading to airway obstruction. Only three patients were treated using curative surgery; the majority received palliative and supportive forms of treatment. In addition, only three patients were offered radiotherapy. Chemotherapy was not offered to any patient. Only two patients were confirmed to still be alive during the study period. The median survival time for the other patients was 3 months; in the majority of cases the patient died within the first year following diagnosis. CONCLUSION: Our experience with ATC demonstrated concordance with other institutions with respect to current clinical profile, presentation, and prognosis. An absence of distant metastases and lymph node involvement was associated with improved survival outcomes, whereas age at diagnosis and tumor size did not affect survival. Curative surgery offers the most effective means of prolonging survival. Radiotherapy and chemotherapy in combination with surgery represents a promising treatment strategy.

Fluoxymesterone-induced gynaecomastia in a patient with childhood aplastic anaemia.

Gynaecomastia is a benign condition characterised by enlargement of the male breast. Drug-induced gynaecomastia merits deep consideration as it may account for as many as 25% of all cases of gynaecomastia in adults. Although the mechanism is not fully clear, some mechanisms include oestrogen-like activities, stimulation of testicular production of oestrogens, inhibition of testosterone synthesis or blockade of androgen action. Anabolic steroids, in particular when used during the pubertal stage, may cause significant irreversible gynaecomastia. We report a case of 28-year-old Filipino man with persistent gynaecomastia from fluoxymesterone used for aplastic anaemia during his prepubertal stage. Hormonal work ups for gynaecomastia all turned out normal, thus isolating the drug as the cause. The patient was unable to undergo breast reconstruction surgery due to haematological contraindications, but eventually referred to psychiatry for counselling. This case will highlight the paradoxical effect of androgenic steroid used during childhood on male breast proliferation during puberty.

Distal renal tubular acidosis in primary hyperparathyroidism.

Primary hyperparathyroidism manifests biochemically as a disturbance in serum calcium homeostasis. The kidney appears to be the central organ that sets the serum calcium level. Hyperchloraemia, defective urinary acidification and renal tubular acidosis have been reported to be associated with primary hyperparathyroidism. Distal renal tubular acidosis due to primary hyperparathyroidism is rarely reported. Renal tubular dysfunction due to significant hypercalciuria appears to be one of the proposed mechanisms. This case report will highlight a case of primary hyperparathyroidism in a 26-year old Filipino man due to a solitary functioning parathyroid adenoma presenting with recurrent nephrolithiasis leading to distal renal tubular acidosis manifesting with hypokalaemia and hypomagnesaemia. The patient underwent a minimally invasive selective parathyroidectomy that resulted in full reversal of hypercalcaemia and hyperparathyroidism together with the features of distal renal tubular acidosis. He is currently on frequent follow-up for monitoring of electrolyte abnormalities and gradual resolution of nephrocalcinosis.

Incidental diagnosis of rectal cancer in a patient with papillary thyroid cancer

BACKGROUND: Differentiated thyroid cancer is a common endocrine malignancy with an indolent course and high overall survival rate. With more cases diagnosed early, survivors of this cancer live longer and hence are at risk of second primary cancers. In patients with known primary malignancy, work-up often focuses on the primary disease, so that coexistence of another primary malignant lesion can be missed.CASE PRESENTATION: We report a case of a 78 year-old Filipino male diagnosed to have papillary thyroid cancer with nodal metastases presenting with an incidental rectosigmoid cancer on pre-operative workup.TREATMENT AND OUTCOME: Patient eventually underwent complete surgical removal of both malignancies. He is currently on levothyroxine suppression therapy with no evidence of tumor recurrence for both malignancy and is on close follow-up for cancer recurrence surveillance.CONCLUSION: Clinical vigilance for cancer screening and surveillance is mandatory for patients diagnosed with any type of primary malignancy to reduce the rate of missing secondary primary malignancy simultaneously present in the same patient , Early cancer detection might improve cancer patient's overall prognosis and eventually proved to be life-saving.

Validation of salivary cortisol among Filipino adults suspected with Cushing's syndrome

BACKGROUND: Cushing's syndrome is a state of hypercortisolism manifesting non-specific clinical; features where its diagnosis entails biochemical confirmation of cortisol excess. this study aims to validate the efficacy of midnight salivary cortisol as a screening test for Filipino suspected with Cushing's syndrome and determine the cut-off value applicable in the local setting. METHODS: This is a cross-sectional study of Filipinos suspected with endogenous Cushing's syndrome seen at a tertiary hospital. Modification of plasma cortisol measured by RIA was used to measure salivary cortisol. The sensitivity, specificity, positive predictive curve, negative predictive curve and area under the screening tests were estimated and compared using 48 hour low dose dexamethasone suppression test (LDDST) as the reference standard. RESULTS: The determine cut-off value (? 7.0 nmol/L) for salivary cortisol showed a relatively high sensitivity (91.3%) and specificity (89.5%) in detecting cases suspected of Cushing's syndrome. One milligram (1mg) dexamethasone suppression test had the highest sensitivity (100%) but had the lowest specificity (68.4%) as a screening test. The area under the curve of the three diagnostic test appeared to be similar when compared with the low dose dexamethasone suppression test. CONCLUSIONS: Using a cut-off value of 7nmol/L, local utility if late-night salivary cortisol has a high sensitivity and specificity in detecting Cushing's syndrome. It has a similar efficiency with 24-hour urine free cortisol and 1mg dexamethasone suppression test as a screening test for Cushing's syndrome. Salivary cortisol may be considered as a valid initial screening test for Filipinos suspected of cushing's syndrome.

Overwhelming hypercalcaemia in mandibular ameloblastoma.

Ameloblastoma is considered to be a benign odontogenic tumour of epithelial in origin that is slow growing but recurrent and invasive in nature. Some of its features have been sources of debate among experts regarding its benign or malignant character. We report a case of a 20-year-old Filipino woman with right mandibular ameloblastoma presenting with overwhelming hypercalcaemia. Work ups for hypercalcaemia eventually revealed tumoral hypercalcaemia, which was initially controlled with intravenous bisphosphanate. The patient eventually underwent tumour excision and mandibular reconstruction, which totally corrected hypercalcaemia. This case will highlight the rare association of hypercalcaemia among patients with ameloblastoma.

Spondylitic psoriatic arthritis presenting as acute urinary retention.

Psoriatic arthritis is a seronegative arthropathy occurring in the presence of psoriasis. In majority of cases, typical psoriatic skin lesions precede joint disease, making diagnosis of psoriatic arthritis without typical skin lesions, a diagnostic challenge. Nail lesions are commonly seen in patients affected by this condition, making it a useful clue in the diagnosis of psoriatic arthritis. This is a case of a 58-year-old Filipino woman presenting with sudden acute urinary retention and weakness of both lower extremities accompanied with active polyarthritis. Onycholytic nail changes initially thought to be a fungal nail infection led to the diagnosis of psoriatic arthritis involving the spine. The patient was eventually treated with methotrexate and non-steroidal anti-inflammatory drugs leading to full resolution of symptoms. The patient is currently ambulatory and on regular follow-up. This case report highlights the importance of clinical and physical findings particularly the nails that would lead to a diagnosis of psoriatic arthritis.

Splenic actinomycosis mimicking malignant lymphoma - A rare case of abdominal actinomycosis

BACKGROUND: Splenic Actinomycosis is a rare entity which usually presents as a difficult diagnostic case. It is a chronic granulomatous infectious disease, caused by Actinomyces which is commonly associated with history of abdominal surgery and manipulation. Majority of cases would present as an enlarging abdominal mass often mimicking malignant tumors.CASE PRESENTATION: This paper presents a rare case of splenic actinomycosis in a 24-year-old Filipino female presenting as multiple splenic abscesses leading to gradual progressive ascites initially thought to be due to a malignant lymphoma. On physical examination, massive ascites and splenomegaly were the only abnormality appreciated. Initial radiologic imaging (x-ray, ultrasound, CT scan) revealed presence of multiple splenic nodules associated with extensive mediastinal and retroperitoneal lymphadenopathy as well as peritoneal extension/carcinomatosis (Figure 1 and 2). Splenic biopsy revealed presence of actinomyces (Figure 3).TREATMENT AND OUTCOME: Patient was started on amoxicillin 2.0 g per day for 24 months which led to a significant resolution of her massive ascites. Subsequent abdominal ultrasound showed gradual reduction in the hepatic and splenic size with resolution of splenic foci. Patient is currently on frequent follow-up.CONCLUSION: Splenic actinomycosis although extremely rare should be included as a differential diagnosis when presented with an unusual splenic mass or abscess on CT scan. Majority would mimic different forms of malignancy hence early histologic biopsy is usually needed to prevent unnecessary extensive and invasive surgical procedures. Radiologic and biochemical test are usually non-specific and not helpful with the establishment of the diagnosis. Although surgery remains to be the cornerstone for its management, prolonged antibiotic therapy might show promising results due to intensive closer follow up and accessibility to monitoring modalities for treatment response.

A survey of knowledge, attitudes and practices of sedation and analgesia among medical residents and pulmonary fellows-in-training at the University of the Philippines-Philippine General Hospital

BACKGROUND: Providing sedation and analgesia for patients especially in the intensive care units remains difficult and controversial for clinicians and many institutions.OBJECTIVE: The purpose of this study is to describe the knowledge, attitudes and practices on sedation and analgesia among medical residents and pulmonary fellows-in-training in a tertiary care hospital.METHODS: The research design is a prospective descriptive survey of 67 participants.RESULTS: Midazolam is the preferred sedative agent for continuous infusion. The top two reasons why sedation is used according to the knowledge of the study participants were agitation and patient comfort. Monitoring neurologic status is the primary reason why sedation is not used. Majority of the medical residents said that 50% of the mechanically ventilated patients require continuous intravenous sedation. On the other hand, pulmonary fellows-in-training said that 50-75% of mechanically ventilated patients require continuous intravenous sedation. Twenty three participants (34.32%) have used a sedation scale, of which majority uses Ramsay Sedation Scale. Morphine is the preferred analgesic agents of the study participants. Unavailability of analgesic agents is the top reason why analgesia is not used.CONCLUSION AND RECOMMENDATION: The medical residents and pulmonary fellows-in-training showed differences inknowledge, attitudes and practices with regard to use of sedation and analgesia. To increase their knowledge and improve their practice, they should be given medical education and training in sedation and analgesia.

Fountain of steroid from an ectopic ACTH-producing tumour.

This case is of a 39-year-old Filipino woman who within 2 months developed, Cushing's features she had no known comorbidities and no history of steroid intake. The patient also presented with hyperpigmentation of knuckles and toes, metabolic alkalosis and persistent hypokalaemia noted as proximal muscle weakness. The patient was referred to our institution for acutely worsening behavioural and psychiatric changes. Work-up for endogenous Cushing's syndrome revealed a significant adrenocorticotropic hormone production from an ectopic source. Further imaging was requested to locate the tumour, but the patient eventually succumbed to the drastic complications of hypercortisolism. On autopsy, the patient was found to have an ectopic well-differentiated neuroendocrine tumour located at the pancreatic head with metastasis to the right hepatic lobe.

'Golden Kernels within the skin': disseminated cutaneous gout.

Presented in this paper is a case of a young Filipino man presenting with recurrent acute gouty flares leading to chronic tophaceous gout and unusual cutaneous manifestations (miliary gout, panniculitis, ulcerations). Unusual sites within the body (torso, shoulder, forearms, thigh) revealed multiple urate dermal deposition. Self-medication with steroids eventually led to secondary Cushing's syndrome and eventual emergence of metabolic complications.

Rachitic chest in a young adult male: Fanconi's syndrome--idiopathic type.

Presented in this paper is a case of a 36-year-old Filipino man presenting with a chronic history of intermittent proximal muscle weakness and paralysis which was associated with failure to thrive, severe bony deformities, muscle wasting and multiple electrolyte abnormalities (hypokalaemia, hypocalcaemia, hypomagnesaemia). Severe skeletal deformities led to a pathological fracture of the femoral bone and restrictive chest wall expansion during inspiration necessitating admission and consult at our institution. Correction of multiple electrolyte abnormalities was the mainstay of treatment for this case and resulted into full reversal of paralytic symptoms but skeletal and osseous abnormalities persisted. This case highlights the insidious course and subtle signs of Fanconi's syndrome leading to disfiguring skeletal deformities and abnormalities if not diagnosed early. Early suspicion and eventual diagnosis might be the key for these patients to have normal productive life devoid of crippling complications.
