Extranodal nasal-type natural killer/T-cell lymphoma with nasal septal perforation.

There are very few reports of extranodal nasal-type NKTL with septal perforation, as seen in our patient. In addition, extranodal nasal-type NKTL is often diagnosed as chronic inflammation on histopathological examination. Therefore, if nasal septal perforation does not improve with appropriate conservative treatment, clinicians should consider a malignant disease such as extranodal nasal-type NKTL.

A robust approach for industrial small-object detection using an improved faster regional convolutional neural network.

With the increasing pace in the industrial sector, the need for a smart environment is also increasing and the production of industrial products in terms of quality always matters. There is a strong burden on the industrial environment to continue to reduce impulsive downtime, concert deprivation, and safety risks, which needs an efficient solution to detect and improve potential obligations as soon as possible. The systems working in industrial environments for generating industrial products are very fast and generate products rapidly, sometimes leading to faulty products.

Positional changes in the uvula tip after adenotonsillectomy in children: preliminary result.

Background: Adenotonsillectomy has become the primary treatment for children with sleep-disordered breathing or obstructive sleep apnea. However, few studies have investigated positional changes in the soft palate or uvula after adenotonsillectomy in children. The present study aimed to evaluate positional changes in the uvula tip using cephalometric analyses after adenotonsillectomy in children.

Number of seasonal exposures to Japanese cedar pollen increases the risk of sensitization: Observational study in Korean adults.

Sensitization to seasonal allergens usually requires repeated exposure to them. However, research on the extent of exposure that increases the risk of sensitization to specific allergens is lacking. Therefore, we investigated the levels of exposure to Japanese cedar pollen that increased the risk of sensitization to it.

Computed Tomography Findings in Patients with Samter's Triad: An Observational Study.

Samter's Triad is a disorder characterized by chronic rhinosinusitis (CRS) with nasal polyps (NPs), asthma, and intolerance to cyclooxygenase-1 inhibitors. However, there have been no studies investigating the prediction of Samter's Triad using imaging findings. Therefore, the authors aimed to investigate whether there is a difference in computed tomography (CT) findings between patients who have CRS with NPs and those with Samter's Triad.

Chronological changes in rhinitis symptoms present in school-aged children with allergic sensitization.

Introduction: It is difficult to accurately predict the natural course of allergic rhinitis (AR), because it is affected by a wide variety of environmental influences, as well as genetic predisposition. Considering the high prevalence of allergic rhinitis in children and adolescents, caregivers should be given appropriate information regarding the disease course. This study aimed to understand the prognosis of allergic rhinitis by examining the relationship between allergic sensitization and rhinitis symptoms during this developmental period.

Predictive local receptive fields based respiratory motion tracking for motion-adaptive radiotherapy.

Extracranial robotic radiotherapy employs external markers and a correlation model to trace the tumor motion caused by the respiration. The real-time tracking of tumor motion however requires a prediction model to compensate the latencies induced by the software (image data acquisition and processing) and hardware (mechanical and kinematic) limitations of the treatment system. A new prediction algorithm based on local receptive fields extreme learning machines (pLRF-ELM) is proposed for respiratory motion prediction.

The association between the parenting stress of the mother and the incidence of allergic rhinitis in their children.

Objectives: The prevalence of allergic rhinitis and the social burden related to the management of allergic rhinitis have persistently increased. There are many studies investigating the association between the allergic diseases of children and the stress of their parent. However, the relationship between parenting stress and the incidence of allergic rhinitis among children requires further investigation.

Mucosal Melanoma Originating From the Eustachian Tube.

A 77-year-old man was referred with a 4-month history of hearing impairment and ear fullness of the left ear. Otoscopic examination revealed an effusion in the left middle ear, and nasal endoscopic examination revealed a dark polypoid lesion at the opening of the left Eustachian tube. In addition to the lesion of the Eustachian tube, a dark mucosal lesion was seen at the posterior choana and the posterior end of the nasal septum.

The role of adjuvant external beam radiation therapy for papillary thyroid carcinoma invading the trachea.

Purpose: To evaluate the effect of adjuvant external beam radiation therapy (EBRT) on local failure-free survival rate (LFFS) for papillary thyroid cancer (PTC) invading the trachea.

Materials And Methods: Fifty-six patients with locally advanced PTC invading the trachea were treated with surgical resection. After surgery, 21 patients received adjuvant EBRT and radioactive iodine therapy (EBRT group) and 35 patients were treated with radioactive iodine therapy (control group).

Relationship between various anthropometric measures and apnea-hypopnea index in Korean men.

Objective: Body mass index (BMI) has been shown to be strongly correlated with severity of OSA. However, BMI has not been shown to be correlated with sleep apnea in all patients studied. The purpose of this study was to evaluate the relationship between various anthropometric measures and severity of OSA according to BMI in men.

Sialolithiasis of an Accessory Parotid Gland Causing Mid-Cheek Pain.

A 52-year-old woman presented with a slightly painful swelling of the right cheek area without postprandial aggravation of the symptom last 1 week. On physical examination, an approximately 1.5 cm sized firm, slightly tender mass was palpated on the right mid-cheek region, and she did not show any abnormal findings on neurologic examination.

Serum periostin level is not associated with allergic rhinitis or allergic sensitization in Korean children.

Objectives: Periostin is a matricellular protein, synthesized in the airway epithelium and induced by interleukin (IL)-4 and IL-13. The significance of periostin as a biomarker of T helper type 2 cell (Th2)-induced airway inflammation, and as a measure of the response to Th2-targeted therapy, has recently been highlighted. We explored the relationship between serum periostin and allergic rhinitis in Korean children.

An object localization optimization technique in medical images using plant growth simulation algorithm.

The analysis of leukocyte images has drawn interest from fields of both medicine and computer vision for quite some time where different techniques have been applied to automate the process of manual analysis and classification of such images. Manual analysis of blood samples to identify leukocytes is time-consuming and susceptible to error due to the different morphological features of the cells. In this article, the nature-inspired plant growth simulation algorithm has been applied to optimize the image processing technique of object localization of medical images of leukocytes.

New allergen sensitization might be associated with increased body mass index in children.

Background: Results of previous studies have shown a relationship between obesity and allergic diseases. However, concrete evidence about the association between obesity and allergies has been lacking.

Objective: The present study aimed to evaluate the potential association between body mass index (BMI) and the change in sensitization on skin-prick tests in children over a 2-year follow-up period.

The association between serum lead and total immunoglobulin E levels according to allergic sensitization.

Background: Results of several studies showed that blood lead concentration is positively associated with total immunoglobulin E (IgE) value. However, no study has investigated whether allergic sensitization could be responsible for the association between lead exposure and total IgE value.

Objective: We investigated whether there was difference in the association between lead exposure and the total IgE value, depending on the presence or absence of Dermatophagoides farinae sensitization.
