Diffuse infiltrating retinoblastoma is an extremely rare form of retinoblastoma which is characterized by its atypical growth pattern. This unusual presentation adds complexity to the diagnostic process. The purpose of this paper is to report a rare presentation of diffuse infiltrating retinoblastoma presenting after an ocular trauma. We described a 7-year-old Filipino boy presenting with total hyphema following an ocular trauma. Comprehensive ophthalmologic clinical and diagnostic evaluations were performed including visual acuity, slitlamp biomicroscopy, ocular ultrasound, neuroimaging, and histopathology post enucleation to determine diagnosis. The misleading, atypical presentation of diffuse infiltrating retinoblastoma may delay diagnosis. While this dilemma is expected in these scenarios, it should be remembered that timing of diagnosis in retinoblastoma is crucial, as this also equates to optimal management. One should remain vigilant for these uncommon presentations especially in the setting of any intraocular inflammation in children.

BACKGROUND

Tuberculosis (TB) has long been a recognized infectious disease contributory to worldwide mortalities. Most cases are from low- to middle-income countries, including the Philippines. Hepatobiliary TB comprises only a small portion of extrapulmonary TB. Tuberculous liver abscess (TLA) usually presents with nonspecific findings causing delay in the diagnosis. Due to this, further reports are needed for early detection along with timely treatment for future courses.

CASE

Presenting a 17-year-old male who came in with right upper quadrant abdominal pain associated with intermittent fever. The symptoms persisted and eventually progressed to abdominal distention, weight loss and jaundice. Initial laboratories were taken including an ultrasound finding of a complex lesion in the hepatic lobe. He was initially managed with empiric antibiotic therapy – Ciprofloxacin and Metronidazole, however, despite it, there was persistence of right upper quadrant pain, abdominal distention and jaundice. Due to this, further work-up was done with drainage of the abscess. Cultures were taken revealing tubercle bacilli along with other microbial growth. Antibiotics and antituberculosis medications sensitive to the microorganisms were started. With the noted improvement of jaundice and abdominal distention and resolution of pain and fever, he was discharged.

CONCLUSION

 Tuberculous liver abscess is an uncommon presentation of extrapulmonary tuberculosis in an
immunocompetent male with right upper quadrant abdominal pain and jaundice. Although TB is endemic in the
Philippines, this gastrointestinal involvement is often not immediately recognized. Thus, with any suspicion of liver abscess,
tuberculous (TLA) type should be included in the differentials for early diagnosis and management.

BACKGROUND

Perimyocarditis due to inflammation of the pericardium and myocardium results in myocellular damage. Myocarditis, or myocardial inflammation, occurs after cardiac injury. Gallbladder edema, in the absence of cholecystitis, may occur in numerous conditions including cardiac inflammation.

CASE PRESENTATION

A 28-year-old previously healthy female presented with chest pain, orthopnea, exertional dyspnea and a history of fever. She also reported intermittent right upper quadrant pain. Physical exam revealed a pericardial friction rub. Electrocardiogram (ECG) showed sinus rhythm with nonspecific ST-T changes; troponin I was elevated. Echocardiography demonstrated segmental wall motion abnormalities, pericardial thickening and preserved systolic function. Initially managed as acute coronary syndrome, she was later diagnosed with perimyocarditis. On the second hospital day, she developed recurrence of right upper quadrant abdominal pain. Abdominal ultrasound revealed gallbladder edema with pericholecystic fluid, but no stones. Liver enzymes were elevated. Acalculous cholecystitis was considered and cholecystostomy offered instead due to aspirin therapy. However, repeat imaging showed resolution of cardiac and gallbladder findings, and surgery was deferred. Cardiac MRI postdischarge was unremarkable.

CONCLUSION

Perimyocarditis may present with gallbladder edema mimicking acalculous cholecystitis, potentially leading to unnecessary surgical intervention. This case emphasizes the importance of considering cardiac etiologies in atypical abdominal presentations.

OBJECTIVE

This study aimed to identify the different risk factors for developing sepsis in patients undergoing percutaneous nephrolithotomy

METHODS

This is a case-control study of all patients who underwent percutaneous nephrolithotomy in the National Kidney and Transplant Institute from 2017 to 2021. Demographic, stone characteristics, perioperative data and post-operative parameters were recorded. The association of clinical variables and sepsis was determined using logistic regression analysis.

RESULTS

A total of 536 patients who underwent percutaneous nephrolithotomy were included in the study with 58 of them suffering from sepsis with a prevalence rate of 9.9%. The majority [392 (67.82%)] of the patients were 31-59 years old. Majority of patients suffering from sepsis also belonged to the same age group were predominantly male [33 (56.9%)], mostly diabetic [15 (26.32%)] and hypertensive [14 (24.56%)] and underwent previous PCNL [49 (8.45%)]. Imaging of patients who had sepsis showed staghorn calculi [30 (51.72%)] with mild [20 (34.48%)] and moderate [23 (39.66%)] seen on imaging. Patients who were requiring transfusion post operatively (Grade II Clavien-Dindo Classification) were seen to have sepsis.

CONCLUSION

The following factors are contributory to the development of sepsis: a high Guy's stone score, high degree of obstruction or hydronephrosis, previous stone surgery and a higher volume of blood loss.

Introduction: Sodium-glucose cotransporter-2 (SGLT2) inhibitors are cornerstone therapies for heart failure and diabetes, offering proven cardiorenal benefits. However, expanded use necessitates vigilance regarding adverse effects, particularly genitourinary infections. While mild cystitis is common, serious upper urinary tract infections remain rare and potentially life-threatening. We describe a case of renal abscess presenting as recurrent urinary tract infections (UTI) following SGLT2 inhibitor initiation, emphasizing the need for clinical vigilance. Case: A 69-year-old male with a significant cardiovascular history, including heart failure with reduced ejection fraction (HFrEF), hypertrophic cardiomyopathy with an implantable cardioverter-defibrillator for non-sustained ventricular tachycardia, diabetes mellitus, hypertension, and hyperlipidemia, presented with a 1-week history of right flank pain, dysuria, urinary frequency, and fever. Initial labs confirmed infection: leukocytosis (22.6 × 10³/ µL), markedly elevated CRP (200 mg/L), and bacteriuria. He was diagnosed with a UTI and started on IV Cefuroxime. This marked his third UTI admission in 5 months, following discharge just 3 weeks prior for septic shock secondary to UTI, establishing a relapsing pattern. Subsequent urine and blood cultures were unremarkable. Medication review revealed Dapagliflozin had been initiated for HFrEF 8 months ago. Following clinical improvement from each prior UTI episode, Dapagliflozin was consistently restarted. Despite an initial antibiotic response, symptoms recurred after discharge each time. The recurrent nature of his infections prompted a renal ultrasound revealing a large (5.3 × 7.5 × 7.4 cm), non-drainable, heterogeneously hypoechoic collection at the left kidney’s mid-lower pole, diagnostic of an early renal abscess. Conclusion This report highlights renal abscess as a rare and severe complication of SGLT2 inhibitor therapy. It serves as a critical reminder that recurrent or relapsing UTIs in patients on these agents should prompt immediate investigation with renal imaging to rule out deep-seated pathology rather than simple cystitis. While these drugs offer proven cardiorenal benefits, their role in promoting urological infections necessitates a cautious approach.

A 53-year-old male with uncontrolled diabetes mellitus who presented with progressive scrotal swelling and straining was found to have a scrotal mass highly suggestive of scrotal abscess on inguinoscrotal ultrasound. Incision and drainage of abscess revealed a mass extending from the bulbous urethra. Subsequent urethrotomy revealed a large stone enclosed in a wide based urethral diverticulum. Urethral diverticulum (UD) is a rare urologic disease entity with a prevalence rate of 0.5 to 5% for both sexes. One complication of UD includes the formation of stone calculi which only occurs in 1% to 10% of all UD cases. UD calculi masqueraded by scrotal abscess has caused diagnostic dilemma as reported cases are often misdiagnosed. Furthermore, the lack of a standard guideline for surgical management of UD in males has led to individualization of the surgical technique done in reported cases. Only 2 other similar cases have been reported in literature worldwide.

Sepsis is a life-threatening organ dysfunction caused by the host's dysregulated response to infection, with a complex pathogenesis and high mortality rate. Currently, there are no clear and effective treatment drugs available. Epigenetic modification serves as a major mechanism regulating gene expression under pathological and physiological conditions, and it has been shown to play a critical role in regulating the occurrence and development of sepsis. Histone acetylation modification, as a sophisticated epigenetic modification mechanism, plays a crucial regulatory role in many aspects of life. It can jointly regulate the acetylation status of histones through histone acetyltransferase (HAT) and histone deacetylase (HDAC), thereby changing DNA expression and dynamically regulating sepsis related gene expression at the epigenetic level. Previous studies have shown that histone acetylation can participate in the progression of sepsis by regulating inflammatory mediators, nuclear factor-ΚB (NF-ΚB) signaling pathway, autophagy, efferocytosis, ferroptosis, pyroptosis. These mechanisms are promising targets for novel sepsis treatments. In addition, with the deepening of research, it has been found that various selective/non selective histone deacetylase inhibitors (HDACI) can regulate histone acetylation status by acting on different HDAC targets, which has been shown to alleviate organ damage caused by sepsis and improve prognosis in septic animal models. This article further summarizes the role and potential applications of histone acetylation in sepsis, providing new ideas for the treatment of sepsis.

Septic shock, a prevalent critical condition in intensive care units (ICU) and a major cause of patient mortality, is fundamentally attributed to microcirculatory dysfunction. Traditional macrocirculatory parameters are often insufficiently sensitive to reflect microcirculatory status. Consequently monitoring peripheral microcirculatory function holds crucial significance for assessing disease progression and evaluating therapeutic efficacy in septic shock. The peripheral perfusion index (PPI), obtained from a standard pulse oximeter, is based on photoplethysmography (PPG). It calculates the differential absorption of red and infrared light emitted by the sensor between pulsatile arterial blood and non-pulsatile tissue, enabling real-time reflection of peripheral perfusion and thus providing non-invasive, continuous monitoring of microcirculatory function. Although often overlooked compared to other ICU monitoring parameters, PPI has demonstrated notable clinical advances in septic shock management. Specifically, in early identification, PPI combined with sequential organ failure assessment (SOFA) predicts disease progression, with its dynamic changes further aiding prognosis assessment. During fluid resuscitation, it guides fluid responsiveness evaluation and serves as a therapeutic target to optimize strategies. In circulatory support, it assists in determining vasoactive drug initiation timing and dosage titration. Additionally, PPI aids mechanical ventilation weaning and organ dysfunction evaluation. This article reviews the principles, influencing factors, and clinical application advances of PPI in septic shock, aiming to provide clinicians with a basis for individualized intervention, improved patient outcomes, and the advancement of precision medicine in septic shock management.

OBJECTIVE: To explore the correlation between albumin (Alb) combined with diuretic treatment and the mortality risk of septic patients with pre-existing congestive heart failure based on the United States Critical Care Medical Information Database-IV (MIMIC-IV), and to conduct the external validation. METHODS: A retrospective cohort study was conducted. The clinical data of septic patients with pre-existing congestive heart failure admitted to the intensive care unit (ICU) from 2008 to 2019 in the MIMIC-IV 2.0 were extracted, including demographic characteristics, comorbidities, laboratory indicators on the first day of ICU admission, severity of illness, treatment measures, etc. For external validation, clinical data were collected from septic patients with pre-existing congestive heart failure admitted to the ICU of the Second People's Hospital of Shenzhen from October 2022 to December 2023. The patients were divided into Alb alone group and Alb combined with diuretic group. The ICU mortality was defined as the primary outcome event, and the 30-day and 60-day mortality were defined as the secondary outcomes. Multivariate Cox proportional hazard regression analysis was conducted to investigate the relationship between Alb combined with diuretic treatment and the mortality risk of ICU and 30 days in septic patients with pre-existing congestive heart failure, and subgroup analysis was performed. Kaplan-Meier survival curve was plotted to compared the 60-day cumulative survival rate between the Alb alone group and Alb combined with diuretic group. RESULTS: (1) Analysis results of data from MIMIC-IV: a total 1 754 patients were enrolled, of which 378 in the Alb alone group, and 1 376 in the Alb combined with diuretic group. Compared with the Alb alone group, the patients in the Alb combined with diuretic group had significantly lower ICU, 30-day, and 60-day mortality [ICU mortality: 19.11% (263/1 376) vs. 30.42% (115/378), 30-day mortality: 18.90% (260/1 376) vs. 32.54% (123/378), 60-day mortality: 24.49% (337/1 376) vs. 39.15% (148/378), all P < 0.05]. Based on the multivariate Cox proportional hazard regression adjusted models considering demographic characteristics, comorbidities, laboratory indicators, severity of illness, and treatment measures, it was shown that the use of Alb combined with diuretic was significantly associated with a reduced risk death of ICU and 30 days [ICU mortality risk: hazard ratio (HR) = 0.597, 95% confidence interval (95%CI) was 0.460-0.774, P < 0.001; 30-day mortality risk: HR = 0.557, 95%CI was 0.433-0.716, P < 0.001]. Subgroup analysis revealed that after adjusting for variables, regardless of gender, age, and whether or not patients had comorbidities such as hypertension, diabetes, severe liver disease, acute renal insufficiency, and sequential organ failure assessment (SOFA) score, the ICU mortality risk was significantly reduced in patients treated with Alb combined with diuretic (all HR < 1, P < 0.05), with no interaction observed (all P > 0.05). Kaplan-Meier survival curve showed the 60-day cumulative survival rate of patients in the Alb combined with diuretic group was significantly higher than that in the Alb alone group (Log-rank test: χ ² = 49.62, P < 0.05). (2) External validation: a total of 385 patients were enrolled, of which 144 in the Alb alone group, and 241 in the Alb combined with diuretic group. Compared with the Alb alone group, the patients of the Alb combined with diuretic group had significantly lower ICU, 30-day, and 60-day mortality [ICU mortality: 19.92% (48/241) vs. 31.25% (45/144), 30-day mortality: 19.09% (46/241) vs. 28.47% (41/144), 60-day mortality: 24.07% (58/241) vs. 34.03% (49/144), all P < 0.05]. The results of multivariate Cox proportional hazard regression analysis, subgroup analysis, and Kaplan-Meier survival curve analysis were consistent with the data analysis of the MIMIC-IV database. CONCLUSIONS Combination therapy of Alb and diuretic was associated with reduced mortality risk in septic patients with pre-existing congestive heart failure.

OBJECTIVE: To observe change in serum growth differentiation factor 11 (GDF11) and killer cell lectin-like receptor B1 (KLRB1), to construct a nomogram model for 28-day death in patients with septic shock, and to explore its predictive value. METHODS: A prospective observational study was conducted. The patients with septic shock admitted to the emergency intensive care unit (ICU) of Cangzhou Central Hospital from September 2023 to March 2025 were selected as the septic shock group, the patients with sepsis admitted to the emergency general ward during the same period were selected as the sepsis group, and healthy individuals undergoing physical examination during the same period were selected as the control group. On the day of hospital admission or physical examination for the research subjects, the levels of serum GDF11 and KLRB1 were detected by enzyme-linked immunosorbent assay (ELISA). The patients with septic shock were divided into survival and death groups based on their 28-day survival status. The patients' gender, age, past medical history, infection site, severity of illness, mechanical ventilation, blood purification, infection indicators, biochemical indicators, coagulation function indicators, and blood lactic acid (Lac) were collected. The clinical data of the patients with septic shock between the two groups with different prognoses were compared. Multivariate Logistic regression analysis was used to screen the risk factors for 28-day death in patients with septic shock, and bivariate Pearson correlation analysis was conducted. A nomogram model was constructed based on the risk factors for 28-day death in patients with septic shock. The discrimination and calibration of the nomogram model were evaluated using the receiver operator characteristic curve (ROC curve), Hosmer-Lemeshow goodness-of-fit test, and calibration curve. The clinical utility of the model was evaluated using clinical decision curve analysis (DCA). RESULTS: A total of 168 patients in the emergency ICU were enrolled in the septic shock group, 40 patients in the emergency general ward were enrolled in the sepsis group, and 40 healthy individuals were enrolled in the control group. Compared with the healthy control group, the serum GDF11 levels in the sepsis and septic shock groups were significantly increased (μg/L: 13.09±3.51, 19.28±5.36 vs. 4.17±0.92, both P < 0.05), and the serum KLRB1 levels were significantly decreased (ng/L: 57.36±11.28, 45.52±9.07 vs. 84.19±17.16, both P < 0.05), with more significant changes in the septic shock group (both P < 0.05). Among the 168 patients with septic shock, 96 survived and 72 died within 28 days. Compared with the survival group, the serum GDF11 level in the death group was significantly increased (μg/L: 24.24±4.81 vs. 15.56±4.62, P < 0.05), and the serum KLRB1 level was significantly decreased (ng/L: 28.53±8.69 vs. 58.26±9.45, P < 0.05). There were also statistically significant differences in sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation II (APACHEII) score, procalcitonin (PCT), activated partial thromboplastin time (APTT), D-dimer, and Lac between the two groups. Multivariate Logistic regression analysis showed that SOFA score [odds ratio (OR) = 1.96, 95% confidence interval (95%CI) was 1.38-3.65), Lac (OR = 1.38, 95%CI was 1.09-2.01), GDF11 (OR = 1.54, 95%CI was 1.21-2.33) and KLRB1 (OR = 0.64, 95%CI was 0.41-0.78) were independent risk factors for 28-day death in patients with septic shock (all P < 0.05). Bivariate Pearson correlation analysis showed that SOFA score was significantly positively correlated with Lac and GDF11 (r value was 0.37 and 0.58, respectively, both P < 0.05), and significantly negatively correlated with KLRB1 (r = -0.72, P < 0.05). A nomogram model was constructed based on the risk factors for 28-day death in patients with septic shock. ROC curve analysis showed that the area under the ROC curve (AUC) of the nomogram model for predicting 28-day death in patients with septic shock was 0.963 (95%CI was 0.929-0.990), indicating that the model had good discrimination and predictive ability. The Hosmer-Lemeshow goodness-of-fit test (χ ² = 9.578, P = 0.295) and calibration curve indicated that the predicted values of the model were in good agreement with the actual values. DCA indicated that the model provided a high net benefit for clinical decision-making. CONCLUSIONS The serum GDF11 level was significantly increased and the KLRB1 level was significantly decreased in patients with septic shock. The nomogram model based on GDF11 and KLRB1 could more accurately evaluate the 28-day death of patients with septic shock.
