Introduction: Severe hypercortisolism is associated with profound impairment of both innate and adaptive immune responses, predisposing affected individuals to opportunistic infections. Excess glucocorticoids alter leukocyte trafficking, suppress pro-inflammatory cytokine production, and impair cellular immunity, increasing susceptibility to bacterial, viral, and fungal pathogens. In some cases, severe infections may precede the diagnosis of Cushing syndrome and represent the initial clinical manifestation. Early recognition is important as untreated hypercortisolism can lead to substantial morbidity and mortality. Case: A young adolescent male presented with progressive facial fullness and facial hyperpigmentation for 4 months, followed by 1 month of intermittent fever, cough, lower limb weakness, and hallucinations. On examination, he was tachypneic with cushingoid features including moon facies, pigmented acne over the face and chest, and nail bed hyperpigmentation. He was hypertensive and had severe hypokalemia with lymphopenia. Radiological imaging demonstrated multiple cavitary lung lesions and intracranial tuberculomas. Bronchoalveolar lavage identified multiple opportunistic pathogens, including Pneumocystis jirovecii, Aspergillus fumigatus, and Haemophilus influenzae, while cerebrospinal fluid testing was positive for cytomegalovirus. Given the unusual combination of infections, an underlying immunocompromised state was suspected. Endocrine evaluation revealed markedly elevated serum cortisol, with loss of diurnal rhythm and elevated adrenocorticotropic hormone (ACTH). Twenty-four-hour urinary cortisol was significantly increased, confirming severe ACTHdependent Cushing syndrome. Magnetic resonance imaging of the pituitary gland and computed tomography imaging of the thorax, abdomen, and pelvis did not identify the source of ACTH secretion. Conclusion This case highlights that overwhelming opportunistic infections may be the first manifestation of severe Cushing syndrome in children. Excess cortisol disrupts host defenses by impairing neutrophil chemotaxis and macrophage phagocytosis, suppressing T-cell-mediated immunity, and reducing cytokine signaling necessary for pathogen clearance. These mechanisms contribute to susceptibility to simultaneous bacterial, fungal, and viral infections. Clinicians should therefore consider underlying hypercortisolism in patients presenting with multiple or unusual opportunistic infections to enable earlier diagnosis and appropriate multidisciplinary management.

Introduction: Endogenous Cushing syndrome is a rare manifestation of chronic cortisol excess. It may present with severe hypercortisolism complicated by life-threatening opportunistic infections. Surgical management of a cortisol-secreting tumor is the mainstay of therapy. However, when the source is not found or when surgery is not feasible, medical therapies may be employed for rapid control of hypercortisolism. CASE: A 13-year-old male presented with breathlessness for one day. He also had a cough associated with weight loss, weakness, and hallucinations for 1 month. On presentation, he was tachypneic and had moon facies, acne, fine moustache, limb wasting, and pigmented nail beds. He was also hypertensive and developed an episode of seizure during admission. Investigation results showed severe hypokalemia and lymphopenia. Radiological examination revealed pneumothorax with multiple lung cavitations and brain tuberculomas. Bronchoalveolar lavage (BAL) was positive for Aspergillus fumigatus. However, both BAL and CSF PCR and culture for TB were negative. Serum ACTH was 379 pg/mL (0–46), and morning serum cortisol was 2,948 nmol/L with loss of diurnal rhythm. His 24-hour urine cortisol was 14,252 nmol/24 hour (31.7–282). This is consistent with ACTH-dependent Cushing syndrome. He was started on anti-TB and anti-fungal treatment. Serum cortisol levels were persistently high while on high-dose intravenous dexamethasone treatment for TB meningitis. An MRI pituitary and a CT scan thorax, abdomen, and pelvis could not reveal an ACTH-secreting tumor source. Metyrapone was started and titrated upwards to control the hypercortisolism. Serum cortisol reduced to 200–300 nmol/L after 1 month, and 24-hour urinary cortisol was down to 22.4 nmol/24 hour after 4 months, requiring weaning of metyrapone doses. Conclusion Metyrapone is effective in the rapid control of severe hypercortisolism with life-threatening complications, as illustrated in this case. However, it warrants careful monitoring and titration.

Malignant gastric outlet obstruction (MGOO) occurs in 2% to 25% of patients with pancreatic ductal adenocarcinoma (PDAC) who do not undergo surgical intervention. Over the past decade, duodenal self-expandable metal stent (D-SEMS) has been widely used for MGOO and has demonstrated high technical (89.1% to 100%) and clinical (85.7% to 94.3%) success rates.Endoscopic ultrasonography-guided gastroenterostomy (EUS-GE) has emerged as a promising alternative with comparable technical (89.3% to 98.9%) and clinical (89.0% to 100%) success rates. Notably, EUS-GE reduces the 6-month reintervention rate by approximately 25% relative to D-SEMS in patients with MGOO, thus making it an increasingly popular treatment option. Despite its advantages, EUS-GE may not be suitable for patients with massive ascites, extensive peritoneal carcinomatosis, gastric linitis plastica, or an inaccessible small bowel. Moreover, EUSGE requires a longer procedure time and incurs higher overall costs, even when considering the increased reintervention rate associated with D-SEMS. While the risk of adverse events is similar between EUS-GE and D-SEMS, EUS-GE requires a higher level of operator expertise to ensure safety and may also require deeper levels of anesthesia than D-SEMS. Advancements in cancer therapy have prolonged survival in PDAC patients, but most do not require reintervention for MGOO, unlike those with other malignancies. Thus, EUS-GE may be suitable for patients with a longer life span who are willing to undergo deep anesthesia at a high-volume center with an experienced specialist. Given these considerations, more comprehensive studies are needed before EUS-GE can be recommended as a standard replacement for D-SEMS in the treatment of MGOO.

Background: Delivering a poor prognosis to patients and their families is critically challenging in pediatric populations. The application of palliative care (PC) provides a bridge between accepting the occurrence of mortality and offering lifelong support.However, little is known about the specifics of PC. This study aims to explore the unmet need for PC in pediatric populations. Methods: We retrospectively reviewed the medical records of mortality cases in the Department of Pediatric Hematology and Oncology at Chang Gung Memorial Hospital. Statistical tests, including Chi-square and Student’s t-tests, were applied to determine the differences between early and late intervention groups in terms of the timing of PC introduction. Results: During the study period, 41 patients were included. Their median age was 11.8 years (IQR, 7.6-15.9). The majority of the disease statuses were refractory or relapsing (R/R). The incidence of memento application was significantly higher in the early intervention group (47.6% vs. 10%, P=0.0081). Vital signs variations tended to be end-of-life (EoL) indicators in this study. Conclusion The early introduction of PC encourages families to accompany their beloved child. EoL signs in the pediatric population include vital sign variations. With the presence of relevant EoL signs, clinical physicians can apply PC earlier to meet the needs.

Purpose: Colorectal cancer (CRC) often spreads to the liver, necessitating surgical treatment for CRC liver metastasis (CRLM). Iron-deficiency anemia is common in CRC patients and is associated with fatigue and weakness. This study investigated the effects of iron-deficiency anemia on the outcomes of surgical resection of CRLM. Methods: This population-based, retrospective study evaluated data from adults ≥20 years old with CRLM who underwent hepatic resection. All patient data were extracted from the 2005–2018 US National (Nationwide) Inpatient Sample (NIS) database. The outcome measures were in-hospital outcomes including 30-day mortality, unfavorable discharge, and prolonged length of hospital stay (LOS), and short-term complications such as bleeding and infection. Associations between iron-deficiency anemia and outcomes were determined using logistic regression analysis. Results: Data from 7,749 patients (representing 37,923 persons in the United States after weighting) were analyzed. Multivariable analysis revealed that iron-deficiency anemia was significantly associated with an increased risk of prolonged LOS (adjusted odds ratio [aOR], 2.76; 95% confidence interval [CI], 2.30–3.30), unfavorable discharge (aOR, 2.42; 95% CI, 1.83–3.19), bleeding (aOR, 5.05; 95% CI, 2.92–8.74), sepsis (aOR, 1.60; 95% CI, 1.04–2.46), pneumonia (aOR, 2.54; 95% CI, 1.72–3.74), and acute kidney injury (aOR, 1.71; 95% CI, 1.24–2.35). Subgroup analyses revealed consistent associations between iron-deficiency anemia and prolonged LOS across age, sex, and obesity status categories. Conclusion In patients undergoing hepatic resection for CRLM, iron-deficiency anemia is an independent risk factor for prolonged LOS, unfavorable discharge, and several critical postoperative complications. These findings underscore the need for proactive anemia management to optimize surgical outcomes.
