Treatment outcomes of oral leukoplakia on the irradiated or nonirradiated mucosa among survivors of head and neck cancer in the papulation where practice of betel nut chewing and cigarette smoking are widespread.

BACKGROUND: Radiotherapy (RT) has numerous effects on the oral mucosa, primarily genetic alterations and changes in the microenvironment. The characteristics of oral leukoplakia (OL) may differ between patients who have received previous head and neck cancer (HNC) treatment with radiation therapy and those who have not. Due to a lack of data on this scenario, we aimed to investigate the surgical outcomes of OL by comparing these two patient groups. METHODS: This retrospective cohort study enrolled a total of 224 OL lesions in 124 patients who underwent carbon dioxide laser (CO2 laser) surgery from July 2002 to Aug 2021. All patients had received previous treatments for HNC, with 59 patients undergoing only surgical approach, 65 patients undergoing RT, and 46 patients undergoing concurrent chemotherapy during RT. The analysis was performed on a per-lesion basis, not a per-capita basis. We investigated the associations of clinicopathological characteristics and treatment outcomes of OL lesions that developed from irradiated or nonirradiated oral mucosa. RESULTS: The median follow-up time was 5.87 years. Postoperative recurrence of OL occurred in 30 patients. Malignant transformation occurred in 17 patients with the incidence rate 4.19% annually and 13.7% cumulatively. The average time for OL transforming into squamous cell carcinoma was 3.27 ± 3.26 years (median 1.82, range 0.11 - 11.90). In univariate analysis, non-homogeneous morphology (P = 0.042), moderate to high-grade dysplasia (P = 0.041), and nonirradiated oral mucosa (P = 0.0047) were predictors for malignant transformation. However, in the Cox proportional hazard model, only nonirradiated oral mucosa remained an independent prognostic factor related to postoperative malignant transformation of OL (P = 0.031, HR 5.08, CI95 1.16 - 22.25). CONCLUSION: In the population whose OL is strongly aetiologically linked to environmental carcinogens such as betel nut and tobacco, OL lesions that develop on previously irradiated oral mucosa have a lower risk for postoperative malignant transformation compared to those that develop on nonirradiated mucosa. This finding highlights the potential impacts of radiation on OL. Further research is needed to confirm this observation and elucidate the underlying mechanism.

Fungal Abscess of Anterior Nasal Septum Complicating Maxillary Sinus Fungal Ball Rhinosinusitis Caused by Aspergillus flavus: Case Report and Review of Literature.

Anterior nasal septum abscess is not a rare clinical disease entity. In terms of the etiologies of the disease, bacteria are obviously more common than fungi. Fungal culture and pathological examination are essential for diagnosis of a fungal abscess of the anterior nasal septum and the basis of prescription of antifungal agents. We report a 57-year-old male patient who came to our outpatient clinic due to refractory nasal congestion for 3 weeks despite receiving treatments by a local medical doctor. Radical surgery with postoperative adjuvant radiotherapy for the right buccal cancer was carried out 14 years ago. The patient has diabetes mellitus and the blood sugar level has been well controlled by oral hypoglycemic agents over the past several years. Computed tomography revealed an abscess in the anterior septum along with rhinosinusitis. Incision and drainage of the nasal septum abscess and functional endoscopic sinus surgery were carried out. Fungal culture and pathological examination confirmed a fungal abscess in the anterior nasal septum and fungal ball rhinosinusitis. Antibiotics and an antifungal agent were given, and the postoperative course was uneventful. A dialectical argument was made regarding the causal relationship between the fungal abscess of the anterior nasal septum and maxillary fungal ball sinusitis. A literature review of the previous case reports was carried out to elucidate the immune status of patients of this disease. In order to reach a rapid establishment of a fungal abscess of the anterior nasal septum, clinicians should keep this disease in mind and remain vigilant. An immuno-compromised status is more commonly found in patients with fungal abscess of the anterior nasal septum and is another important characteristic of this disease. Prompt diagnosis and effective treatment are equally important in patients with lower immune status of this kind, and the latter is based on the former.

Modified Killian Method for Flexible Nasopharyngoscopic Observation of the Hypopharynx: A Systematic Review and Meta-Analysis.

OBJECTIVE: Flexible nasopharyngoscopy is a common procedure for evaluating the hypopharynx. The modified Killian method has been reported to enhance visualization during this examination. The aim of this study was to compare the visibility of the hypopharynx using conventional and modified Killian methods. METHODS: A systematic literature search was conducted in PubMed, EMBASE, and the Cochrane Library to identify studies that compared the visibility of the hypopharynx using the 2 methods. Comprehensive meta-analysis software was used to analyze the data. Studies that evaluated the overall hypopharyngeal visibility score and the visibility of the pyriform sinus, postcricoid region, and upper esophageal sphincter were included. RESULTS: Five studies were included in the analysis. The pooled results showed that the modified Killian method significantly improved overall visibility score (SMD=1.09; 95% CI, 0.39-1.80) and complete visibility of the pyriform sinus, postcricoid region, and upper esophageal sphincter (log OR=3.83; 95% CI, 2.30-5.35; log OR=4.20; 95% CI, 3.21-5.19; log OR=3.38; 95% CI, 1.68-5.08). CONCLUSION: The modified Killian method is a valuable technique for improving hypopharyngeal visibility during flexible nasopharyngoscopy. This technique can enhance the detection of potential abnormalities or lesions, leading to better diagnostic accuracy and improved patient outcomes.

Postauricular incision versus conventional transcervical incision in submandibular gland excision: A systematic review and meta-analysis.

Surgical removal of the submandibular gland is indicated for different conditions affecting the gland, such as neoplasm, sialadenitis, and sialolithiasis, and different types of surgical approaches have been reported. The purpose of this meta-analysis was to evaluate the differences between the postauricular approach and conventional transcervical approach in submandibular gland excision. A systematic review was performed using PubMed, Embase and the Cochrane Library to identify studies comparing outcomes of submandibular gland surgery via the postauricular approach and conventional transcervical approach. The data of interest were analyzed with Comprehensive Meta-Analysis software (version 3; Biostat, Englewood, NJ). Dichotomous data and continuous data were analyzed by calculating the risk difference (RD) and the mean difference (MD) with the 95% confidence interval (CI), respectively. The results show that the postauricular incision is a feasible approach to access the submandibular gland, and compared with the conventional transcervical approach, it requires a longer operative duration but has a similar complication rate and yields better cosmetic outcomes.

Postauricular Incision Versus Modified Blair Incision in Parotidectomy: A Systematic Review and Meta-Analysis.

OBJECTIVE: The mainstay of first-line treatment of parotid tumors is adequate surgical removal. The present study was conducted to compare the differences between parotidectomy with postauricular incision (PI) and modified Blair incision (MBI). DATA SOURCES: A systematic search of PubMed, Embase and the Cochrane Library was performed. METHODS: The data of interest and study characteristics were extracted from the included studies. Statistical analysis was performed with Comprehensive Meta-Analysis software (version 3; BioStat, Englewood, NJ). Dichotomous data and continuous data were analyzed by calculating the risk difference and the mean difference with the 95% confidence interval respectively. RESULTS: Four retrospective studies were included in the present meta-analysis. The pooled results revealed that the cosmetic satisfaction score was higher in the PI group (MD = 2.67; 95% CI, 2.12 to 3.23) and that intraoperative blood loss was lower in the PI group (MD = -55.35; 95% CI, -100.33 to -10.36). The operative duration (MD = -5.15; 95% CI, -24.06 to 13.75), tumor size (MD = -.07; 95% CI, -.27 to .13) and incidences of common postoperative complications were comparable between the two groups. CONCLUSIONS: According to these findings, the use of PI in parotidectomies may be one of the options for improving cosmetic outcomes. This technique may be considered if oncological safety can be secured.

Sleep deprivation and immunoglobulin E level.

Objectives: Sleep deprivation is a common issue for modern people and leads to many morbidities and mortality. Some papers also suspected the relationship between Immunoglobulin E (IgE) level and sleep deprivation. The purpose of this article is to make the vicious circle between serum IgE level and sleep deprivation clear. Materials and methods: In this study, we included 4,460 population aged around 48 years old respective 2,145 males and 2,315 females enrolled in the National Health and Nutrition Examination Survey (NHANES). Sleep durations were recorded, in hours, in whole numbers by the participants. The levels of total IgE were measured by anti-IgE. All procedures were analyzed using SPSS version 18 (SPSS, Inc., Chicago, IL, USA). Result: The statistical significance between higher IgE level and ≤5 h sleep duration was noted (Beta coefficients: 64.04, 95% confidence interval (CI): 2.35, 125.72, P = 0.042). In sex difference, the correlation between short sleep duration and high serum IgE levels was noted in male [Beta coefficients: 120.225 (P = 0.008)] but not in female. There were no positive findings in the ethnicity-based correlation between serum IgE levels and sleep duration. Conclusion: This study indicated that short sleep duration (≤5 h) is associated with higher serum IgE levels, especially in men. Further longitudinal investigations concerning the effect of sleep deprivation on serum IgE might provide a better explanation for the pathophysiology underlying autoimmune disease and sleep deprivation.

The Big Five Personality Traits as Predictors of Negative Emotional States in University Students in Taiwan.

Negative emotional states, such as stress, anxiety, and depression, are prevalent in university students. Personality traits have been shown to be associated with a wide range of behaviors in students, such as academic motivation, achievement, and social well-being. The aim of this study was to investigate the association between the Big Five personality traits and negative emotion states in university students in Taiwan. A cross-sectional study was conducted on 580 university students in Taiwan. Negative emotional states were evaluated using the Depression Anxiety Stress Scale-21 (DASS-21) and the Big Five personality traits were measured using the 48-item Big Five Inventory. A hierarchical linear regression analysis was used to assess the factors associated with DASS-21 scores. Neuroticism (standardized beta [std. ß] = 0.45, p < 0.001) and openness (std. ß = 0.12, p = 0.003) were significantly associated with DASS-21 scores, while agreeableness (std. ß = -0.10, p = 0.007) was significantly and inversely associated with DASS-21 scores. Personality traits could be used to identify students at risk of negative emotional states and to undertake appropriate preventive strategies.

Association between oral intake magnesium and sarcopenia: a cross-sectional study.

BACKGROUND: Sarcopenia is a common skeletal muscle disorder in the elderly population. The patients with sarcopenia increased the cost of care and the risk for hospitalization. Magnesium deficiency might increase reactive oxygen species and protein damage. The purpose of our study was to demonstrate the relation between oral intake magnesium and sarcopenia by European Working Group on Sarcopenia in Older People (EWGSOP) 2 definition. METHODS: Our study included 2532 participants with 1310 males and 1222 females. The multiple logistic regression model was designed to test the cross-sectional protective outcome of oral intake magnesium for sarcopenia. RESULTS: Oral intake magnesium had a protective outcome with sarcopenia (odd ratio (OR) = 0.997, 95% CI = 0.996, 0.998, P < 0.001). After fully adjusted, the significance persisted with OR = 0.998 (95% CI = 0.996, 0.999, P < 0.001). CONCLUSION: Results of the present study showed the dose dependent relationship between oral intake magnesium and sarcopenia. Sufficient oral intake magnesium might prevent patient from sarcopenia.

Unraveling the relationship between serum 25­hydroxyvitamin D levels and trabecular bone score in American adults.

INTRODUCTION: Trabecular bone score (TBS) is a novel way for clinicians to evaluate bone quality. It is directly associated with the mechanical strength of bones and helps predict fractures. Vitamin D, a secosteroid that enhances calcium absorption, is commonly used to strengthen the skeletal system. OBJECTIVES: The present analysis aimed to determine the relationship between vitamin D levels and TBS by analyzing data from the National Health and Nutrition Examination Survey. PATIENTS AND METHODS: A total of 4464 persons (2148 men and 2316 women) were included in our study. The participants were analyzed according to sex, obesity status, and T­score using regression models. RESULTS: We noted a remarkably positive relationship between serum levels of 25­hydroxyvitamin D (25[OH]D) and TBS after the results were fully adjusted (ß = 0.319; 95% CI, 0.145-0.494; P <0.001). T­score analysis showed that serum 25(OH)D levels were related to TBS in the group of participants with normal bone mineral density (T­score >-1) (ß = 0.311; 95% CI, 0.097-0.525; P = 0.005). However, in the osteopenia (T­score between -1 and -2.5) and osteoporosis (T­score <-2.5) group there was no such association (P >0.05). CONCLUSIONS: Our study shows that low serum levels of 25(OH)D may decrease the TBS, which represents the skeletal microarchitecture and is a fracture risk factor in individuals with normal T­scores.

Postauricular Incision Versus Conventional Transcervical Incision in Second Branchial Cleft Cyst Excision: A Systematic Review and Meta-Analysis.

Surgical removal is the treatment of choice for second branchial cleft cysts (SBCCs), which are congenital anomalies. The conventional procedure is performed through a transcervical approach, which would lead to a visible scar in the anterior neck. Conversely, the postauricular approach could keep the scar in the hairline or retroauricular sulcus, rendering it almost invisible after the surgery. The purpose of this meta-analysis was to evaluate the differences between the postauricular and conventional transcervical approaches to SBCC excision. A systematic review was performed using PubMed, Embase, and the Cochrane Library to identify studies comparing outcomes of SBCC surgery via postauricular and conventional transcervical approaches. The data of interest were analyzed with Comprehensive Meta-Analysis software (version 3). The data of interest were analyzed by calculating the risk difference (RD), the standardized mean difference, and the mean difference (MD) with the 95% confidence interval (CI). Three studies were eligible for the final analysis. The pooled analysis demonstrated that the cosmetic satisfaction score was significantly higher with the postauricular approach (standardized mean difference, 2.12; 95% CI, 0.68-3.56). The operative duration was significantly longer with the postauricular approach than with the conventional transcervical approach (MD, 12.81; 95% CI, 2.39-23.23). The incidences of postoperative marginal mandibular nerve palsy (RD, 0.00; 95% CI, -0.09 to 0.09), bleeding complications (RD, -0.02; 95% CI, -0.09 to 0.05), salivary complications (RD, -0.00; 95% CI, -0.07 to 0.06), cyst size (MD, 0.02; 95% CI, -0.96-0.99), and length of hospital stay (MD, -2.50; CI, -7.30 to 2.30) were comparable between the 2 groups. The postauricular approach is feasible for use in SBCC excision and yields better cosmetic outcomes, a longer operative duration, and a similar rate of complications.

Endoscope-assisted versus conventional neck dissection in patients with oral cancer: a systematic review and meta-analysis.

BACKGROUND: Neck dissection is an integral component of the treatment of head and neck cancers. The present meta-analysis aimed to compare the use of endoscope-assisted neck dissection (END) with conventional neck dissection (CND) in the existing English literature. METHODS: A search of PubMed (MEDLINE), Embase, and the Cochrane Library for articles reporting the results of the two techniques of neck dissection was completed independently by two individuals. The authors analyzed the data from each study using a random-effects model. RESULTS: The pooled analysis demonstrated comparable lymph node yield, intraoperative blood loss, incidence of locoregional recurrence, and incidence of complications between the two groups. A significantly longer operative time but a shorter length of hospital stay was observed in the END group compared with the other group. CONCLUSIONS: Compared with conventional techniques, END offers similar oncologic outcomes and complication rates; however, it requires a longer operative time. Future studies with long-term follow-up and assessment of patient satisfaction are needed to confirm the clinical use of END.

Post-Irradiation Sinus Mucosa Disease in Nasopharyngeal Carcinoma Patients Treated with Intensity-Modulated Proton Therapy.

In the past decade, patients with nasopharyngeal cancer (NPC) have been deemed candidates for proton radiotherapy, due to the large and comprehensive target volumes and the necessity for the retention of the surrounding healthy tissues. In this study, we aimed to compare the incidence and severity of post-irradiation sinusitis by detecting sinus mucosa diseases (SMDs) via the magnetic resonance imaging (MRI) of patients with NPC after intensity-modulated proton therapy (IMPT) and volume-modulated arc therapy (VMAT). A total of 53 patients in the IMPT group and 54 patients in the VMAT group were enrolled in this study. There were significantly lower endoscopic scores and Lund-Mackay staging scores determined from MRI scans in the IMPT group during different follow-up periods. For the most vulnerable sinuses, the incidence and severity of SMD were the highest during the third post-radiotherapy month in both groups. These decreased steadily, and there was no significant increase in the incidence and severity of SMD during the second post-radiotherapy year in the IMPT group. Our data show that NPC patients with IMPT have a significantly lower incidence and decreased severity of SMD than those with VMAT. A better and faster recovery of sinonasal function after radiotherapy in the IMPT group was also observed.

Systematic review and meta-analysis of modified facelift incision versus modified Blair incision in parotidectomy.

Surgical removal is the treatment of choice for many neoplasms of the parotid gland. This meta-analysis aimed to evaluate the differences between parotidectomy using a modified facelift incision (MFI) and parotidectomy using a modified Blair incision (MBI). A systematic search of the available literature in PubMed, Embase and the Cochrane Library was performed. Studies of adult patients who underwent open parotidectomy with presumed benign parotid neoplasms based on preoperative examinations were reviewed. The surgical outcomes of the MFI and MBI groups were collected. Intraoperative and postoperative parameters, including operative time, tumor size, cosmetic satisfaction, and incidences of facial palsy, Frey's syndrome and salivary complications, were compared. Dichotomous data and continuous data were analyzed by calculating the risk difference (RD) and the mean difference (MD) with the 95% confidence interval (CI), respectively. Seven studies were included in the final analysis. The pooled analysis demonstrated that the cosmetic satisfaction score was significantly higher in the MFI group (MD = 1.66; 95% CI 0.87-2.46). The operative duration in the MFI group was significantly longer than that in the MBI group (MD = 0.07; 95% CI 0.00-0.14). The MFI group exhibited a smaller tumor size (MD = - 2.27; 95% CI - 4.25 to - 0.30) and a lower incidence of Frey's syndrome (RD = - 0.18; 95% CI - 0.27 to - 0.10). The incidence of postoperative temporary facial palsy (RD = - 0.05; 95% CI - 0.12 to 0.03), permanent facial palsy (RD = - 0.01; 95% CI - 0.06 to 0.03) and salivary complications (RD = - 0.00; 95% CI - 0.05 to 0.05) was comparable between the two groups. Based on these results, MFI may be a feasible technique for improving the cosmetic results of patients who need parotidectomy when oncological safety can be ensured.

Differences in clinical and imaging presentation of maxillary sinus fungus ball with and without intralesional hyperdensity.

Maxillary sinus fungal balls (MSFBs) mostly occur in older individuals and demonstrate female predominance. Early diagnosis is important to avoid treatment delays. Intralesional hyperdensity (IH) indicates the presence of heavy metal deposition within fungal hyphae and has been the most specific characteristic of MSFB on computed tomography (CT). For those without IH on CT, the diagnosis of MSFB remains challenging. This study aimed to characterize clinical presentation of MSFB with and without IH and to study factors contributing to MSFB with no IH formation. We retrospectively identified 588 patients with MSFB. The clinical characteristics and CT findings were reviewed. Patients with unilateral MSFB had a mean age of 57.4 years and demonstrated female predominance (64.63%). The female-to-male ratio was highest at 51-60 years (2.02) and rose to 2.60 in MSFB with IH only. Compared to those with IH, MSFB without IH was significantly more common in males (OR = 2.49), in those with diabetes mellitus (DM) (OR = 1.87), adjacent maxillary odontogenic pathology (OR = 1.75). Complete opacification on CT was less common in MSFB without IH (OR = 0.60). Patients with MSFB without IH were more likely to have DM, no female predominance, adjacent maxillary odontogenic pathology, and partial opacification of the sinus, compared to those with IH. These may be helpful in better understanding of the formation of MSFBs without IH, early identification of them and prevention of post-operative recurrence.

Low-Grade Ovarian Serous Adenocarcinoma with Lymph Node Metastasis in Neck.

Low-grade ovarian serous adenocarcinoma is rarely encountered in the neck region. The diagnosis of this rare malignancy entity in the neck is challenging for both clinicians and pathologists. A 53-year-old female with a chief complaint of a right lower neck mass that had been growing for approximately 2 weeks. The ultrasound-guided fine needle aspiration cytology favored malignancy. The positron emission tomography/computed tomography scan revealed the clustered enlarged lymph nodes with increased radioactivity uptake in the right neck level V, and strong radioactivity uptake was also displayed in the right ovarian regions. Pelvis magnetic resonance imaging displayed right adnexal complex mass supporting the ovarian cancer. An en bloc resection of the right neck lymph node was conducted. Ovarian serous adenocarcinoma with metastasis of lymph nodes in the neck was confirmed through histopathological findings. This study reviews the clinical features of low-grade ovarian serous carcinoma metastasizing to lymph nodes in neck. Although very rare, ovarian cancer with neck metastasis should be considered in the differential diagnosis of a neck mass lesion. The clinical staging would be relatively high due to the quiet entity of the cancer.

Investigation on returning to work in liver cancer survivors in Taiwan: a 5-year follow-up study.

BACKGROUND: Primary liver cancer is the fifth most common malignancy and limits patients' quality of life and working ability. Return to work after cancer treatment is an important step in social recovery. In addition, return to work represents the recovery of financial ability and improvements in self-confidence. The purpose of this article is to discuss the relationship between return to work and various covariables in workers with liver cancer. METHODS: The national registry cohort study collected adult workers newly diagnosed with liver cancer from 2004 to 2010 in Taiwan. There were 2451 workers included in our study. Primary liver cancer was diagnosed by using the International Classification of Diseases for Oncology code. Return to work after liver cancer survival was determined as returning to the same work or reemployment within five years after cancer diagnosis. The associations between independent variables and return to work were analyzed by Cox proportional hazard models. RESULTS: Workers who underwent surgery were more likely to return to work not only in the 2nd year but also in the 5th year. A lower survival rate was noted in the non-return-to-work group (p < 0.001) among all patients with liver cancer. The completely adjusted model identified that the rate of return to work was related to all-cause mortality with a hazard ratio of 0.244 (95% Confidence Intervals: 0.235-0.253). CONCLUSIONS: Our study indicated the impacts of treatment on the return to work of liver cancer survivors. In addition, in patient with liver cancer, return to work had positive effect on the survival rate.

Low urine pH is a risk factor for low muscle mass: A new way to predict sarcopenia.

AIMS: Sarcopenia, one of the primary diseases of the older adult population, is a condition characterized by loss of skeletal muscle mass, strength and functionality. Due to its considerable economic impact, preventive interventions for sarcopenia play an important role in the older adult population. Urine includes many indicators of physiology and pathophysiology. Urine analysis is used to diagnose many different diseases. The goal of this cohort study was to examine the relationship between urine pH level and skeletal muscle mass. METHODS: This community-based cross-sectional study was carried out among 9712 Taiwanese individuals (4992 men and 4720 women). We used urine pH as an independent variable and skeletal muscle mass as a dependent variable. Bioelectric impedance analysis was used to measure the percentage of skeletal muscle mass (PSMM). We collected first fasting morning urine samples after overnight fasting, and urine pH was measured with a dipstick. In the by-sex and by-obesity analyses, we stratified the sample into two subgroups and a linear regression model was used for covariate adjustment. RESULTS: In the fully adjusted model, all-subject analysis showed a statistically significant association between urine pH and the PSMM with a ß coefficient of 0.820 (95% CI 0.615-1.025; P < 0.001). Additionally, by-sex analysis showed that urine pH was related to the PSMM in both sexes, with ß coefficients of 0.261 (95% CI 0.006-0.516; P = 0.045) in men and 0.179 (95% CI 0.029-0.328; P = 0.019) in women. By-obesity status analysis showed that urine pH was related to the PSMM in the body mass index <27 group with a ß coefficient of 0.284 (95% CI 0.101-0.466; P = 0.002) after full adjustment. However, for the body mass index ≥27 group, there was no significant relationship between urine pH and the PSMM (P > 0.05). CONCLUSION: The results showed the impacts of urine pH levels on skeletal muscle mass in both sexes and non-obese populations. Due to its easily accessible and economical characteristics, urine analysis is a convenient way to approach patients with low skeletal muscle mass and predict sarcopenia.

A Retrospective Cohort Study of Oral Leukoplakia in Female Patients-Analysis of Risk Factors Related to Treatment Outcomes.

BACKGROUND: The aim of this study was to make a comparison of clinicopathological characteristics of oral leukoplakia between male and female patients following carbon dioxide laser excision for oral leukoplakia and analyze the factors associated with the treatment outcomes in female patients. METHODS: Medical records of patients with oral leukoplakia receiving laser surgery from 2002 to 2020 were retrospectively reviewed and analyzed statistically. RESULTS: A total of 485 patients were enrolled, including 412 male (84.95%) and 73 female (15.05%). Regarding the locations, the predilection site of oral leukoplakia in male patients was buccal mucosa (p = 0.0001) and that for women patients was tongue (p = 0.033). The differences of recurrence and malignant transformation between both sexes were not significant (p > 0.05). Among female patients, area of oral leukoplakia was the risk factor related to recurrence (p < 0.05). Clinical morphology and postoperative recurrence were the risk factors related to malignant transformation (p < 0.05). CONCLUSIONS: In comparison with male patients, there was no significant difference of the postoperative recurrence and malignant transformation of oral leukoplakia in female patients. Among the female patients, clinicians should pay more attention to large-sized and non-homogeneous leukoplakia, and postoperative recurrent lesions.

Toxoplasmic Lymphadenitis Presenting as a Tiny Neck Tumor.

(1) Background: Toxoplasmic lymphadenitis (TL), caused by the protozoan Toxoplasma gondii, is a worldwide zoonosis. We report a case of TL in the head and neck region diagnosed using ultrasound (US)-guided fine needle aspiration cytology (FNAC), serological tests, and pathological findings. (2) Case Presentation: A 51-year-old female with a chief complaint of a left posterior neck mass that had been growing for approximately 2 weeks. TL was confirmed by histopathological examinations and serological tests. US-guided FNAC and en bloc resection of the lymph node were performed. The diagnosis was confirmed as TL in the neck. (3) Conclusions: We suggest that US-guided FNAC should be considered as the first-line test for assessing a tiny mass before a definitive treatment is chosen.
