Preoperative Signs and Symptoms as Prognostic Markers in Nasal Septoplasty

Identification of preoperative signs and symptoms that may predict the outcome of surgery is important, for both patient selection and the development of interventions for improving outcomes. The purpose of this study was to assess the value of some selected preoperative signs and symptoms for predicting outcomes of nasal septoplasty. Patients undergoing septoplasty with or without turbinoplasty responded to the Nasal Surgical Questionnaire (NSQ) preoperatively and six months postoperatively. The questionnaire contains visual analogue scales (VAS) for nasal obstruction during the day and at night. We compared preoperative and postoperative VAS scores in patients with unilateral versus bilateral septal deviation and patients with low versus high preoperative scores. Of 446 patients undergoing septoplasty from September 2014 to December 2015 who had responded to the preoperative NSQ, 286 (64.1%) also returned the postoperative version. There was greater improvement in obstruction in patients with preoperative unilateral compared to bilateral septal deviation (day scores, ). The grade of deviation and the presence of concomitant bony conchal hypertrophy did not influence results. Patients with lower preoperative VAS scores obtained better end results than those with higher scores (). Type of septal deviation and preoperative VAS scores may aid in predicting outcome of nasal surgery.

Development of anticancer agents targeting the Hedgehog signaling

AbstractHedgehog signaling is an evolutionarily conserved pathway which is essential in embryonic and postnatal development as well as adult organ homeostasis. Abnormal regulation of Hedgehog signaling is implicated in many diseases including cancer. Consequently, substantial efforts have made in the past to develop potential therapeutic agents that specifically target the Hedgehog signaling for cancer treatment. Here, we review the therapeutic agents for inhibition of the Hedgehog signaling and their clinical advances in cancer treatment.

Heterotopic Purkinje Cells: a Comparative Postmortem Study of Essential Tremor and Spinocerebellar Ataxias 1, 2, 3, and 6

AbstractEssential tremor (ET) is among the most common neurological diseases. Postmortem studies have noted a series of pathological changes in the ET cerebellum. Heterotopic Purkinje cells (PCs) are those whose cell body is mis-localized in the molecular layer. In neurodegenerative settings, these are viewed as a marker of the progression of neuronal degeneration. We (1) quantify heterotopias in ET cases vs. controls, (2) compare ET cases to other cerebellar degenerative conditions (spinocerebellar ataxias (SCAs) 1, 2, 3, and 6), (3) compare these SCAs to one another, and (4) assess heterotopia within the context of associated PC loss in each disease. Heterotopic PCs were quantified using a standard LH&E-stained section of the neocerebellum. Counts were normalized to PC layer length (n-heterotopia count). It is also valuable to consider PC counts when assessing heterotopia, as loss of PCs extends both to normally located as well as heterotopic PCs. Therefore, we divided n-heterot…

A Rare Complication After Septoplasty: Visual Loss Due to Right Retinal Artery Spasm

Abstract Septoplasty is a commonly used procedure for correcting septal cartilage deformities. Hemorrhage, abscesses, scaling, adhesions, and scar tissue are often seen after the operation of the septoplasty, but temporary or permanent visual loss due to local anesthetic use has been reported very rarely in the literature. The authors also aimed to present a female patient with retinal artery spasm in the right eye after septoplasty in this article. A 27-year-old female patient was admitted to the authors' clinic with long-standing nasal obstruction and postnasal drip. There was no feature in her history and also no sign other than nasal septal deviation on physical examination. The patient was informed about the operation and the operation was planned. Emergency eye consultation was requested after the patient said that the right eye of the patient had never seen in the postoperative wake-up hall. Examination by an ophthalmologist; mild exotropia and total loss of vision in the r…
