ABSTRACT
Objective@#To determine the prevalence of sinonasal anatomic variations seen on paranasal sinus (PNS) CT scans of a sample of Filipino adults with chronic rhinosinusitis.@*Methods@#Design: Cross-sectional study Setting: Tertiary Government Training Hospital Participants: The PNS CT scans of 51 Filipino patients with chronic rhinosinusitis with and without nasal polyposis diagnosed at our outpatien Department of Otorhinolaryngology-Head and Neck Surgery between October 2015 to December 2020 were reviewed for the presence of sinonasal anatomic variants. The prevalence of the identified variants was calculated.@*Results@#The CT scans of 51 patients, 41 (80.4%) men and 10 (19.6%) women, were included. The median age was 48 years (Q25: 35, Q75: 56, IQR:21). The median Lund Mackay Score (LMS) was 15 (Q25: 12, Q75: 20, IQR:8). Majority (94%) had an LMS of ≥5. The most common anatomic variant in the study population was agger nasi (n=46/51, 90.2% present bilaterally) followed by uncinate process attachment to the lamina papyracea (n=90/102, 88.24%). The third to sixth most common findings were Keros type II classification (n=76/102, 74.51%), nasal septal deviation (n=35/51, 68.62%), optic nerve canal type 1 (n=67/102, 65.69%) and anterior ethmoid artery grade 1 (n=46/102, 45.1%), respectively. Less common variants were Onodi cell (n=13/51, 25.49% unilateral and n=10/51, 19.61% bilateral), Haller cell (n=8/51, 15.69% unilateral and n=1/51, 1.96% bilateral), supraorbital cell (n=4/51, 7.84% unilateral and n=4/51, 7.84% bilateral), middle turbinate concha bullosa (n=3/51, 5.88% unilateral and n=6/51, 11.76% bilateral), superior turbinate concha bullosa (n=2/51, 3.92% unilateral and n=1/51, 1.96% bilateral), pneumatized crista galli (n=2/51, 3.92%) and optic nerve dehiscence (n=1/51, 1.96% bilateral). @*Conclusion@#In the adult Filipino population with CRS sampled in this study, the six most common sinonasal anatomic variants were agger nasi, superior attachment of the uncinate process to the lamina papyracea, Keros type II classification, septal deviation, optic nerve canal type 1 and anterior ethmoid artery grade 1. Pre-operatively, the PNS CT scan of every patient must be meticulously evaluated for the sinonasal anatomic variants to avoid surgical complications.
ABSTRACT
Las urgencias oncológicas son complicaciones comunes de la evolución natural del tumor o de su manejo. Algunas pueden presentarse de manera sutil y ser pasadas por alto, lo que aumenta la morbimortalidad. El objetivo de esta revisión narrativa es recopilar información actualizada de las principales complicaciones oncológicas, para ello se realizó una revisión de artículos originales, revisiones sistemáticas y narrativas en bases de datos como Scopus, SciELO, PubMed, ScienceDirect y en el buscador Google Scholar. Se seleccionaron 63 referencias que mostraran información relevante acerca de las urgencias oncológicas planteadas para el desarrollo del artículo. En la revisión se discute que las complicaciones pueden clasificarse de acuerdo con su origen en infecciosas (neutropenia febril), metabólicas (síndrome de lisis tumoral e hipercalcemia maligna) y obstructivas (síndrome de vena cava superior, obstrucción intestinal, compresión medular y taponamiento cardiaco). El diagnóstico requiere un alto índice de sospecha, el médico debe tener la capacidad resolutiva y el conocimiento necesarios para el manejo y hacer uso racional de los recursos diagnósticos. Es necesario adoptar medidas terapéuticas que impacten positivamente en el pronóstico y que reduzcan la morbimortalidad.
Oncological emergencies are common complications resulting from the natural evolution of the tumor or its management; however, some of them may be subtle or even overlooked, which contributes to greater morbidity and mortality. Our aim was to gather updated information on the main oncological complications. A narrative literatura review was performed by searching for original articles, systematic reviews and narratives, in databases such as Scopus, SciELO, PubMed, ScienceDirect and in the Google Scholar search engine. 63 references were selected that addressed relevant information about the oncological emergencies raised for the development of the article. According to their origin, complications can be classified into infectious (febrile neutropenia), metabolic (tumor lysis syndrome and malignant hypercalcemia) and obstructive (superior vena cava syndrome, intestinal obstruction, spinal cord compression and cardiac tamponade). Facing these complications requires a high level of suspicion; the physician must be able to resolve each complication and have the necessary knowledge to approach each case, with a rational use of diagnostic resources. It is also necessary to adopt therapeutic measures that positively impact patients. patient prognosis, decreasing morbidity and death.
