The Development of an Automatic Thyroid Cancer Staging, Prognosis Predicting and Follow-Up Strategy Suggesting Calculator with Concurrent Data Input Process / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: It takes considerable time and effort to make decisions about management and follow up for the thyroid cancer. Also there are risks of incorrectness or confusion on the part of thyroid specialists. We developed a thyroid cancer calculator that does automatic thyroid cancer staging, prognosis predicting and suggesting follow-up strategies in order to reduce the burden of thyroid specialists who have to memorize a lot of guidelines and statistics, and to give consistency to the treatment plan. MATERIALS AND METHOD: An automatic thyroid cancer calculator was developed by using a computer program called 'Qt 5.2 version', based on patient demographics, diagnosis, treatment, and follow-up status. This partly cited the history of prior thyroid cancer or other cancer registration, and focused on the specification of differentiated thyroid cancer. RESULTS: The program consisted of survival, recurrence and, dynamic re-stratification with follow-up. The patient registration form consisted of identification number, name and operation date, and patients needed to enter their thyroid cancer status, including clinical and pathologic information after registration. The entered information could be easily accessed in a few seconds. The program helped to update patient's current status, promptly collect data for clinical studies of thyroid cancers and provide better patient care. This program was simple, convenient and time-saving for users as it specifically contained important thyroid cancer items. CONCLUSION: Although this program is still in its primitive stage, the Kosin thyroid calculator reduces the workload of thyroid specialists and prevents the loss of clinical data. Furthermore, it could be a useful tool for the management and research of thyroid cancer.

2 Cases of Reduction of Orbital Floor Fracture Using Fibrin Glue for Securing Bioresorbable Panel

Many surgical methods for the reconstruction of orbital floor fractures have been reported, and theseinclude transorbital, transantral and transnasal endoscopic approaches, among others. The choice of surgical approach and materials for the reduction of orbital blowout fractures depends on the surgeon's experience and preference. For the cases of large orbital floor fractures, reduction has beenperformed most frequently through the transantral approach, and the herniated orbital tissue generally has been supported by asilastic block, silastic tube or urethral balloon catheter. However, the transantral approach has significant drawbacks that includethe requirement of removal surgery, displacement of materials, and inflammation of the maxillary sinus. To overcome these negative effects, the authors used fibrin glue tosecure the reduction through the transantral approach in two cases of patients with orbital floor fractures.

A Case of Atypical Maxillary Sinusitis Accompanied with Papillon-Lefevre Syndrome / 대한이비인후과학회지

Papillon-Lefevre syndrome (PLS) is an extremely rare autosomal recessive disorder characterized by palmoplantar keratoderma and periodontitis and occuring with an estimated incidence of 1-4 cases per million. Patients with PLS are highly susceptible to infection. The etiology of an infective susceptibility is unknown; however, an association with defects in neurophil dysfunction, insufficient lymphocyte response to pathogens, defects in monocyte functions and impairment of NK cell cytotoxic function has been suggested. To our knowledge, this is the first case report of atypical maxillary sinusitis accompanied by PLS, and we represent the case with a review of the related literatures.

Delayed Onset Diplopia due to Minimal Orbital Floor Fractures 16 Months Previously / 대한이비인후과학회지

Ocular symptoms related to orbital fracture occur immediately after the fracture in most cases. However, authors experienced a delayed onset diplopia occurred 16 months after orbital floor fracture. A 19-year-old man, who had right orbital floor fracture 16 months ago, presented with diplopia of upward gaze. At the time of the fracture, no surgery was performed because the fracture was minimal and there were no particular symptoms. Physical examinations revealed a minor ocular motility restriction of upward gaze, but orbital floor showed no definite interval change on computed tomography. Severe adhesion between the orbital fat tissue and orbital floor was noted intraoperatively and the adhesion was dissected. After the operation, the patient showed remarkable improvement in diplopia and restriction of the ocular motility.
