INTRODUCTION

There is significantly increased morbidity among patients who undergo major amputation because of diabetic foot ulcers (DFU) . Various risk factors contribute to this outcome with endothelial dysfunction potentially linked to poor wound healing. The Neutrophil Lymphocyte Ratio (NLR) may indicate endothelial dysfunction.

OBJECTIVES

This study aimed to evaluate the accuracy and utility of NLR as a predictor of major amputation in patients admitted for DFU, whose white blood cell counts (WBCs) were elevated or normal. Major amputation is defined as amputation above the tibiotalar joint.

METHODOLOGY

This retrospective cohort analysis included patients admitted at East Avenue Medical Center for DFU. The primary endpoint was major amputation of the lower extremities. Data were analyzed using Receiver Operating Characteristic (ROC) analysis and logistic regression.

RESULTS

The study included 280 DFU patients, predominantly male (62.86%) with a mean age of 57.01±10.72 years. Elevated WBC was found in 176 patients (62.86%) while 104 had normal WBC (37.14%). Major amputation of the lower extremity was performed on 112 patients (40%), with 81 having elevated WBC and 31 normal WBC. The median NLR in patients with elevated WBC undergoing major amputation was 12.86 (IQR: 2.36-95) compared to 5.71 (IQR: 1.91-31.67) in those who did not, indicating NLR as an independent predictor of major amputation (Adjusted OR 1.23; 95% CI 1.14-1.34; p < 0.001). ROC analysis showed an AUC of 0.8234 with an optimal cutoff of 9.33 (72.8% sensitivity, 86.3% specificity). Other predictive variables included University of Texas Stage 3D (Adjusted OR 8.20; 95% CI 2.52-26.75; p < 0.001), Wagner Grade 4 (Adjusted OR 4.6; 95% CI 1.28-16.55; p=0.019), and severe infection (Adjusted OR 2.91; 95% CI 1.22-6.93; p=0.016). For patients with normal WBC, median NLR was 18 (IQR: 1.54-45.5) in those who had major amputation versus 3.13 (IQR: 1.14-12.29) in those who did not undergo major amputation. ROC analysis showed an AUC of 0.9068 with an optimal cutoff of 6.92 (87.1% sensitivity, 98.6% specificity). NLR was also an independent predictor in these subjects (Adjusted OR 1.48; 95% CI 1.14-1.92; p=0.003) alongside smoking history (Adjusted OR 9.14; 95% CI 1.26-66.56; p=0.029) and UT3D (Adjusted OR 17.38; 95% CI 2.21-136.59; p=0.007).

CONCLUSION

Forty percent of DFU patients had major amputations. NLR independently predicted major amputation in DFU patients with both elevated and normal WBC.

Adrenal cortical carcinoma (ACC) is a rare malignancy, and oncocytic ACC (OAC) is a rare histopathologic variant of ACC, with <70 cases documented worldwide as of 2021. This is a case of a 64-year-old female initially presenting with epigastric-to-periumbilical pain, left flank pain, nausea, vomiting, and bloatedness. Computed tomography (CT) urogram revealed a 12.2 x 12.7 x 15 cm left adrenal mass, with pulmonary metastases on chest CT. The patient was clinically and biochemically unremarkable based on the hormonal panel. Left thoracoabdominal adrenalectomy was done, and the left adrenal mass was identified as a high-grade non-functioning OAC on histopathology and immunohistochemistry. The patient showed clinical improvement on chemotherapy with etoposide, cisplatin, doxorubicin (EDP), without mitotane, due to local unavailability. In conclusion, while EDP + mitotane is the standard therapy for metastatic cases, EDP alone showed promising outcomes in improving quality of life and resolving paraneoplastic neuropathy in the absence of mitotane. To date and to the best of our knowledge, this is the first documented case of non-functioning OAC in the Philippines. DS-related Kaposi sarcoma (KS) progresses rapidly with early mucosal and systemic involvement. Early diagnosis and treatment are crucial as they significantly impact the outcome. This is a case of disseminated cutaneous and gastrointestinal KS in a 24-year-old Filipino male living with HIV, presenting with hyperpigmented violaceous subcutaneous nodules, odynophagia, progressive dysphagia, and symptomatic anemia. Capsule endoscopy demonstrated utility in diagnosing gastrointestinal KS lesions, highlighting its crucial role when conventional upper endoscopy was challenging due to oropharyngeal involvement. Diagnostic limitations, mainly the unavailability of human herpesvirus-8 (HHV-8) immunohistochemical stain, were addressed through high clinical suspicion. Multidisciplinary approach including chemotherapy with liposomal doxorubicin, radiotherapy, and supportive care eventually yielded good clinical response. This case emphasizes the importance of early diagnosis, timely intervention, and long-term surveillance in achieving favorable outcomes for patients with KS despite some diagnostic limitations.
