RESUMO

BACKGROUND/AIM: Postnasal drip may be related to several diseases, but not all patients are clearly diagnosed. Patients with chronic, idiopathic postnasal drip symptoms are easily overlooked, and their clinical features are yet to be identified. This study aimed to analyze the clinical features and response to first generation antihistamine-decongestant therapy in patients with chronic idiopathic postnasal drip, suggesting it as a distinct entity. PATIENTS AND METHODS: A retrospective cohort study involving 157 chronic idiopathic postnasal drip patients was conducted, analyzing demographics, symptoms, and treatment response to first-generation antihistamines and nasal decongestants. RESULTS: Mean age of patients was 55.4±17.0 years old. Median duration of symptom was 36 months (range=12-66 months) and severity in the visual analogue scale was 7 (range=5-8). Throat discomfort was the most frequently associated symptom (73.7%). Cough was recorded in 30.3% of patients. Viscosity of postnasal drip was associated with rhinorrhea and throat discomfort. Of the patients, 71.6% responded positively to 1st generation antihistamine-decongestant medication. However, 25.9% of patients presented symptom re-occurrence. Patients with nasal stiffness or persistent symptoms presented a higher re-occurrence rate compared to others. CONCLUSION: This study outlines the clinical features of patients with chronic idiopathic postnasal drip and suggests it as a distinctive entity., This proposal aims to enhance diagnostic precision and promote further research in the field.

RESUMO

Pretreatment values of the neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) are well-established prognosticators in various cancers, including head and neck cancers. However, there are no studies on whether temporal changes in the NLR and PLR values after treatment are related to the development of recurrence. Therefore, in this study, we aimed to develop a deep neural network (DNN) model to discern cancer recurrence from temporal NLR and PLR values during follow-up after concurrent chemoradiotherapy (CCRT) and to evaluate the model's performance compared with conventional machine learning (ML) models. Along with conventional ML models such as logistic regression (LR), random forest (RF), and gradient boosting (GB), the DNN model to discern recurrences was trained using a dataset of 778 consecutive patients with primary head and neck cancers who received CCRT. There were 16 input features used, including 12 laboratory values related to the NLR and the PLR. Along with the original training dataset (N = 778), data were augmented to split the training dataset (N = 900). The model performance was measured using ROC-AUC and PR-AUC values. External validation was performed using a dataset of 173 patients from an unrelated external institution. The ROC-AUC and PR-AUC values of the DNN model were 0.828 ± 0.032 and 0.663 ± 0.069, respectively, in the original training dataset, which were higher than the ROC-AUC and PR-AUC values of the LR, RF, and GB models in the original training dataset. With the recursive feature elimination (RFE) algorithm, five input features were selected. The ROC-AUC and PR-AUC values of the DNN-RFE model were higher than those of the original DNN model (0.883 ± 0.027 and 0.778 ± 0.042, respectively). The ROC-AUC and PR-AUC values of the DNN-RFE model trained with a split dataset were 0.889 ± 0.032 and 0.771 ± 0.044, respectively. In the external validation, the ROC-AUC values of the DNN-RFE model trained with the original dataset and the same model trained with the split dataset were 0.710 and 0.784, respectively. The DNN model with feature selection using the RFE algorithm showed the best performance among the ML models to discern a recurrence after CCRT in patients with head and neck cancers. Data augmentation by splitting training data was helpful for model performance. The performance of the DNN-RFE model was also validated with an external dataset.

RESUMO

Sudden hearing loss is an easily encountered disease in clinics, but its prognosis has not been completely elucidated. In the present study, we investigated the long-term prognosis of sudden hearing loss with 130 patients who were diagnosed based on strict criteria and provided uniform treatment. The patients with incomplete recovery were reevaluated after 2 months without receiving additional treatment. Hearing levels at different time points were compared. Moreover, the associated factors affecting the degree of hearing improvement over time were evaluated using stepwise multiple linear regression. After treatment, 73 out of the 130 (56.1%) patients attained incomplete recovery and were reevaluated after 2 months. Seventeen out of the seventy-three (23.3%) patients showed a grade promotion, fifty-four (74%) were constant, and two (2.7%) were aggravated. The mean interaural hearing differences (IHDs) showed significant improvement. Old age, poor initial IHD, and poor recovery grade were significantly associated with a profitable delayed hearing gain. Poorer hearing level at the time of onset might be a sign for slower recovery rather than a poorer prognostic factor. The treatment outcome of idiopathic sudden sensorineural hearing loss (ISSNHL) should be evaluated at least 2 months after treatment completion, and counseling is required due to the need for long-term follow-up in patients with ISSNHL.

RESUMO

We report a case with rare complication of cerebral venous thrombosis, as well as an incomplete response, after sigmoid sinus resurfacing surgery for pulsatile tinnitus (PT). A 24-year-old female patient with PT originating from the sigmoid sinus underwent sigmoid sinus resurfacing surgery. The tinnitus was immediately resolved, but it recurred with headache 5 days after surgery. A cerebral venous thrombosis was identified and treated, but PT persisted, although its frequency and loudness decreased. Sigmoid sinus resurfacing surgery is a safe and effective method to treat PT, but in some patients, it can cause serious complications and/or persistent tinnitus. In our patient, factors such as changes in blood viscosity due to warfarin intake or increased blood flow due to weight loss may have influenced the persistence of the tinnitus. It is important to identify the various associated factors and the weight of each of these factors to provide more tailored treatment of PT for individual patients in the future and to reduce complications and increase the effectiveness of sigmoid sinus resurfacing surgery.

RESUMO

The role of systemic inflammation has not been clearly defined in thyroid cancers. There have been conflicting reports on whether systemic inflammatory markers have predictive value for thyroid cancers. We aimed to evaluate the association between systemic inflammatory markers and clinicopathological factors in thyroid cancers and to assess their predictive value for thyroid cancers in detail. Five hundred thirty-one patients who underwent surgery for thyroid nodules were included. The patient population consisted of 99 individuals (18.6%) with benign thyroid nodules and 432 individuals (81.4%) with thyroid cancers. In 432 patients with thyroid cancers, neutrophil-to-lymphocyte ratio (NLR) was significantly higher in the cases with tumors greater than 2 cm than in those with tumors less than 2 cm. (p = 0.027). NLR and platelet-to-lymphocyte ratio (PLR) were significantly higher in cases with lateral lymph node metastasis (LNM) than in those without LNM (p = 0.007 and 0.090, respectively). The nodule size was significantly higher in benign thyroid nodules than in thyroid cancers (p < 0.001). When the cases were stratified by tumor size, NLR was a significant predictor of thyroid cancers in cases with nodules greater than 2 cm (Exp(B) = 1.85, 95% CI = 1.15-2.97, p = 0.011), but not in those with nodules less than 2 cm. In thyroid cancers, preoperative NLR was associated with pathological prognosticators such as tumor size and lateral lymph node metastasis. When the size difference between thyroid cancers and benign thyroid nodules was adjusted, NLR could be a significant predictor of thyroid cancers.

RESUMO

OBJECTIVE: To define clear clinical characteristics and management strategies of herniation of temporomandibular joint (TMJ) into the external auditory canal (EAC). DATA SOURCE: MEDLINE, PubMed, and EMBASE databases. STUDY SELECTION: A search was conducted using the keywords "temporomandibular joint" and "herniation" with all of their synonyms. Literature selection criteria included articles published in English, and articles dating back no further than 1970. RESULTS: Forty articles regarding 51 cases were eligible for critical appraisal. According to the previously published papers, TMJ herniation has following characteristics; symptoms are nonspecific, but a distinguishable feature is a protruding mass into the EAC that can be seen to appear and disappear as the mouth opens and closes. High-resolution computed tomography scans are sensitive to the bony defect and are helpful in diagnosing TMJ herniation. In the surgical treatment of TMJ herniation, wall reconstruction rather than simple mass excision could be a safe and long-lasting strategy. CONCLUSIONS: Herniation of TMJ into the EAC is a rare condition, but can be encountered in the clinic at any time. This literature review could be helpful in the diagnosis and treatment of TMJ herniation into the EAC.
