Introduction: Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy, with an incidence of 1–2 cases per million annually. Its occurrence during pregnancy is exceptionally uncommon, presenting significant diagnostic and management challenges due to overlapping physiological changes and concerns for both maternal and fetal outcomes. While most cases are hormonally functional, non-functioning ACC during pregnancy is particularly rare and may result in delayed diagnosis. Case: A 35-year-old Malay female was referred following ultrasonography for persistent back and left flank pain, which revealed a left adrenal incidentaloma and a concurrent 10-week intrauterine pregnancy. There were no clinical signs of hormone excess. Physical examination revealed a normotensive patient with a large, palpable left abdominal mass, without Cushingoid or virilizing features. Magnetic resonance imaging (MRI) demonstrated a 12.1 × 10.3 × 12.8 cm heterogeneous left adrenal mass with cystic and necrotic components, displacing adjacent structures. Hormonal evaluation was within normal limits: 24-hour urinary cortisol 320.2 nmol/24 hours (reference range [RR] 11.8–350), midnight salivary cortisol <3 and 4.2 nmol/L (RR <11.3), plasma metanephrine <0.2 nmol/L (RR <0.5), normetanephrine 0.6 nmol/L (RR <0.9), and 17-hydroxyprogesterone 223 ng/dL (RR <285), consistent with a non-functioning tumor. Following multidisciplinary consultation, the patient underwent open left adrenalectomy at 16 weeks’ gestation. Histopathological analysis confirmed ACC (Weiss score 8/9) without extra-adrenal extension. Surveillance MRI at 32 weeks demonstrated no recurrence or residual mass. At 40 weeks’ gestation, she delivered a healthy infant, and both mother and child remain well on follow-up. Conclusion Non-functioning ACC during pregnancy is rare and poses significant diagnostic challenges. Early imaging, comprehensive hormonal assessment, and timely surgical intervention during the second trimester are essential. Multidisciplinary management is crucial to optimizing maternal and fetal outcomes.

Introduction: Cushing’s syndrome is a multisystem disorder with significant cardiovascular morbidity, yet presentation as acute heart failure is uncommon. When driven by adrenocortical carcinoma (ACC), the clinical course is often aggressive and rapidly fatal, with particularly poor out-comes in resourcelimited settings where access to therapy is constrained. Case: A 39-year-old previously well female presented with acute decompensated heart failure, newly diagnosed hypertension, type 2 diabetes mellitus, and obesity, preceded by a 3-year history of secondary amenorrhea and progressive weight gain. On admission, she exhibited florid Cushingoid features. Biochemical evaluation confirmed severe adrenocorticotropic hormone (ACTH)-independent hypercortisolism: morning serum cortisol 1,950 nmol/L, failure of suppression on overnight dexamethasone suppression test (post-ODST cortisol 2022.9 nmol/L), and elevated 24-hour urinary free cortisol (2,069 nmol/24 hours, 2.56 × upper limit of normal). Androgen excess was evident, with elevated dehydroepiandrosterone sulfate (DHEAS more than 27 µmol/L) and testosterone (9.91 nmol/L). ACTH was suppressed, supporting an adrenal source, while aldosterone was normal. Contrast-enhanced computed tomography demonstrated a large left adrenal mass (12 cm) with tumor thrombus extending into the inferior vena cava and renal veins, with extensive hepatic and pulmonary metastases, consistent with advanced ACC. Management was limited by disease severity and resource constraints. Ketoconazole was contraindicated due to transaminitis, and alternative steroidogenesis inhibitors were unavailable, leaving metyrapone as the only feasible option. Oncological therapy was deferred due to sepsis and clinical instability. Her course was fulminant, complicated by recurrent heart failure, sepsis, and metabolic derangements, culminating in refractory cardiopulmonary failure. She died within 1 month of diagnosis, prior to definitive oncological intervention. Conclusion Fulminant cortisol-secreting ACC may present catastrophically as acute heart failure and progress rapidly. Early recognition and timely access to multimodal cortisollowering therapy are critical, particularly in resourcelimited settings. In fulminant hypercortisolism, the challenge is not diagnosis—but timing.

BACKGROUND

Cyanotic congenital heart disease (CHD) accounts for 20% of all cardiac malformations with an estimated incidence of 2.5–3 per 1,000 live births. An increasing number of patients now survive into adolescence, with or without intervention, forming a unique group requiring specialized care.

To determine factors influencing survival among adolescents with unrepaired cyanotic CHD.

This single-center case-control study was conducted from 2017 to 2022 in a specialized tertiary center in the Philippines. Sample size was based on a 2.6% total fatality rate among infants who underwent CHD operations. Binary logistic regression was used to identify significant predictors of survival, with pRESULTS

Among 125 subjects, 58% (72/125) were males with a median age of 16 years. The median age at diagnosis was 1 year and 1 month; 73% resided outside Metro Manila. Most patients were New York Heart Association (NYHA) Class I (49%), with Tetralogy of Fallot as the most common diagnosis (52%) and 26% had palliative procedures. Predictors of survival included place of origin (OR 0.38, 95% CI 0.15–0.95, p = 0.039), oxygen saturation (OR 1.12, 95% CI 1.06–1.17, pCONCLUSION

Optimizing oxygenation, improving access to care and strengthening targeted interventions are crucial for enhancing survival among adolescents with unrepaired cyanotic CHD.

INTRODUCTION

Early, high-quality cardiopulmonary resuscitation (CPR) improves survival in cardiac arrest. In the Philippines, guidelines specify chest compression depth, but challenges like fatigue and limited staff affect outcomes. This has led to interest in devices like the LUCAS, a portable, battery-powered machine that provides consistent compressions. This study evaluates the clinical profile, outcomes and risks of patients treated with LUCAS at a private tertiary hospital in the Philippines.A

This retrospective cohort study was conducted at a private tertiary hospital, reviewing records of patients who received LUCAS-assisted compressions (March 2023–September 2024) and manual compressions (March 2023–January 2024) based on inclusion criteria.

Out of the 188 cases, 63 patients received mechanical cardiopulmonary resuscitation (mCPR) and 122 received manual compressions. Demographics were similar between the groups with notable differences in hypertension and coronary artery disease prevalence. The causes of arrest varied: arrhythmias and cardiogenic shock were more common in the mCPR group, while septic shock and COVID-19 were predominant in the manual compression group. The mCPR group showed higher survival rates, improved rhythm recovery and lower asystole rates. However, no significant differences in long-term survival or other vital signs were observed between the groups.

The study suggests mCPR may improve immediate outcomes, particularly in cases of arrhythmias and cardiogenic shock, though long-term effects remain unclear. Chest fractures were commonly observed in LUCAS recipients. As the first Philippine study on mechanical CPR, it highlights potential benefits and underscores the need for further research on its risks and broader applications.

Introduction: Thyrotoxicosis typically manifests as a hypermetabolic state characterized by tachyarrhythmias, such as sinus tachycardia or atrial fibrillation. Bradyarrhythmia, specifically atrioventricular block (AVB), is a rare and atypical cardiac manifestation. While Graves’ disease is the leading cause of hyperthyroidism, non-autoimmune etiologies must be considered when thyroid-stimulating antibodies are absent. The exact mechanism for AVB in thyrotoxicosis remains unclear but may involve myocardial inflammation of the conduction system or autonomic dysfunction. Case: A 16-year-old male with no previous medical history presented with a sudden syncopal attack. Clinical evaluation revealed a complete heart block (CHB) in association with biochemical evidence of thyrotoxicosis, requiring a temporary transcutaneous pacemaker insertion. There were no features of Graves’ disease, such as exophthalmos and thyroid acropachy, and further investigation showed a negative thyroid receptor antibody (TRAb) titer with no family history of thyroid disorders. Thyroid ultrasonography showed increased vascularity, while scintigraphy imaging showed diffuse, homogeneous, and increased uptake in both thyroid lobes. The combination of negative serology and the absence of a family history, along with a hyperfunctional state on imaging, likely suggests a rare presentation of sporadic, non-autoimmune, nonfamilial form of thyrotoxicosis. Following the initiation of anti-thyroid therapy, the CHB completely resolved without the need for further cardiological intervention. He achieved a complete clinical remission after a few months and is being planned for radioactive iodine therapy. Conclusion Most of the thyrotoxicosis-associated CHB reported in the literature was due to Graves’ disease or some forms of autoimmune thyrotoxicosis, with auto-antibodies and activated lymphocytes having a role in the pathogenesis of the CHB. CHB in association with a non-autoimmune, non-familial form of thyrotoxicosis is indeed rare, and as this case illustrates, it completely went into spontaneous sinus rhythm upon initiation of conventional anti-thyroid therapy. This rare presentation of CHB is believed to have a benign clinical course.

Introduction: Thyroid stimulating hormone (TSH) suppression following differentiated thyroid carcinoma is widely recommended to reduce recurrence risk. However, this strategy assumes cardiovascular tolerance to supraphysiologic thyroid hormone exposure. In patients with advanced structural heart disease, this assumption may fail, exposing a critical limitation of guideline-directed TSH suppression. Case: We report a 71-year-old male with end-stage renal failure on hemodialysis and severe ischemic cardiomyopathy (ejection fraction 23%) who presented with acute decompensation characterized by dyspnea, rapid atrial fibrillation, and non–ST-elevation myocardial infarction. He had a history of papillary thyroid carcinoma treated with total thyroidectomy and radioactive iodine over 20 years prior and was maintained on levothyroxine 200 mcg daily for TSH suppression. Despite biochemically euthyroid indices (TSH 1.8 mIU/L, free thyroxine 4 17 pmol/L), he developed recurrent arrhythmia with heart failure decompensation. This case highlights a dissociation between biochemical euthyroidism and tissue-level thyrotoxicity in a structurally compromised myocardium. Papillary thyroid carcinoma after definitive therapy typically follows an indolent course with low short-term mortality. In contrast, in severe left ventricular dysfunction, excess thyroid hormone increases adrenergic sensitivity and myocardial oxygen demand, precipitating arrhythmia and ischemia. This risk is amplified in end-stage renal disease, where altered hormone handling renders biochemical indices less reliable. Conclusion Biochemical euthyroidism does not equate to physiological safety. In patients with advanced cardiovascular disease, thyroid hormone therapy should be titrated to cardiovascular tolerance rather than oncologic targets alone, and routine TSH suppression may be inappropriate.

Introduction: The coexistence of autoimmune thyroid disease and type 1 diabetes mellitus is well established; however, their sequential or concurrent presentation in very young children remains uncommon. We demonstrate two paediatric cases with concurrent Graves' disease and type 1 diabetes mellitus, each illustrating distinct complications and clinical courses. Cases: A 3-year-old female presented with anterior neck swelling, weight loss, and persistent tachycardia. Biochemical evaluation confirmed severe thyrotoxicosis (T4 152.3 pmol/L, TSH <0.008 mIU/L) with markedly elevated antithyroglobulin and anti–thyroid peroxidase antibodies. Thyroid ultrasonography demonstrated a diffusely enlarged, hypervascular gland with nodular changes, consistent with Graves’ disease. During longitudinal follow-up, she developed polyuria, polydipsia, and hyperglycemia, with positive pancreatic autoantibodies confirming type 1 diabetes mellitus. Notably, serial early morning cortisol measurements were persistently low, raising concern for evolving adrenal insufficiency and suspicion of autoimmune polyglandular syndrome type 2. Comprehensive endocrine evaluation is ongoing. A 4-year-old male presented with a 1-year history of recurrent self-limiting fever followed by significant fatigability for 1 month. Salient examination on admission revealed tachycardia, anterior neck swelling, and an incidental pansystolic murmur. Thyroid function tests confirmed thyrotoxicosis (T4 38.6 pmol/L, TSH <0.008 mIU/L). Serial serum glucose was markedly elevated on admission, prompting further testing that confirmed type 1 diabetes mellitus with positive pancreatic autoantibodies. Echocardiography demonstrated moderate-to-severe mitral regurgitation with heart failure secondary to prolonged uncontrolled hyperthyroidism state. Cardiac function improved with restoration of a euthyroid state, highlighting the reversible nature of thyrotoxic heart failure. Conclusion These cases highlight the progressive nature of childhood autoimmunity, where Graves’ disease may precede the development of type 1 diabetes mellitus and evolving features of autoimmune polyglandular syndrome type 2. They further emphasize that thyrotoxic heart failure is potentially reversible with restoration of a euthyroid state, underscoring the importance of early recognition and vigilant long-term surveillance.

A 19-year-old female with a 2-day history of involuntary fast jerk-like movements of the left upper and lower extremities presented at the emergency department. Patient had no other known comorbidities and family history was unremarkable. Anti-streptolysin O titer (ASO) and C-reactive protein (CRP) were all normal. Two-dimensional echocardiography (2D Echo) revealed thickened anterior mitral valve leaflet with prolapsed A2 scallop, mild mitral regurgitation, thickened right coronary cusp of aortic valve without restriction of motion, trivial aortic regurgitation, other findings were unremarkable. Patient was managed as a case of Sydenham’s chorea secondary to acute rheumatic fever, with valvular heart disease secondary. Patient was initially started on valproic acid 500mg tablet every 8 hours, benzathine penicillin 1.2M units intramuscular, and carvedilol 12.5mg/tablet twice a day. The patient was then shifted to haloperidol 5mg ¼ tablet twice a day, diphenhydramine 50mg intravenously coinciding with haloperidol doses due to visual side effects of valproic acid. This report highlights the importance of a high index of suspicion and complete history and physical examination in order to diagnose and manage movement disorders in a low-income setting.
