The diagnostic value of the neutrophil-lymphocyte ratio in distinguishing between subarachnoid hemorrhage and migraine

Can Neutrophil-to-Lymphocyte or Platelet-to-Lymphocyte Ratio Be Used to Predict Postoperative Nausea and Vomiting in Breast Reduction?

“…There are various factors related to the risk of nausea and vomiting, and inflammation increases this risk. In several studies, the neutrophil-lymphocyte ratio (NLR) or the thrombocytelymphocyte ratio (PLR) has been suggested as a parameter to be used in the diagnosis and follow-up of the inflammatory diseases [12][13][14][15]. However, although this relationship has been reported in only a limited number of studies for rhinoplasty in the literature, the literature provides no information about this relationship for breast reduction operations.…”

May Neutrophil to Lymphocyte Ratio Serve a Role in the Prediction of Clinical Features of Migraine?

“…However, in this study, migraineurs during the interictal period were not investigated. Eryigit et al also did not find any statistically significant difference in the NLR between migraine and other patients with primary headache syndromes [8]. Nevertheless, this study was in a retrospective design and no data were given regarding if the migraineurs were during the attack period or interictal period.…”

“…NLR is an easily measured, reproducible, and inexpensive marker, and it is a parameter to be used also for subclinical inflammation [25]. Therefore, its utility on the clinical grounds including its diagnostic significance, prognostic role, and its possible contribution regarding the underlying pathophysiology has constituted an attractive topic of research interest [7,8,10]. The prognostic or diagnostic role of NLR has been investigated rather in a limited number of studies focusing on neurological disorders, which included patients with acute stroke, subarachnoid hemorrhage, restless leg syndrome, multiple sclerosis, and headaches [6-8, 10, 13, 26, 27].…”

“…The prognostic or diagnostic role of NLR has been investigated rather in a limited number of studies focusing on neurological disorders, which included patients with acute stroke, subarachnoid hemorrhage, restless leg syndrome, multiple sclerosis, and headaches [6-8, 10, 13, 26, 27]. To the best of our knowledge, there are only three previous reports evaluating the significance of the NLR for the evaluation of patients with migraine [8,10,13]. In the study by Karabulut et al on 92 patients with migraines during the attack period, the value of NLR was found to be higher in the patients, compared to the controls [10].…”

“…However, even when WBC is within normal limits, an increased neutrophil to lymphocyte ratio (NLR) may indicate inflammation and inflammation-related pathologies [4]. The NLR has been used in the evaluation and prognostication of various diseases, including coronary artery diseases, malignancies, rheumatologic diseases, and neurological diseases [5][6][7][8][9][10][11][12]. Few studies have investigated the value of this marker in the evaluation of migraineurs [8,10,13].…”
