ABSTRACT

Laryngopharyngeal foreign bodies are among the cases most frequently encountered by otolaryngologists. Most foreign bodies can be easily removed without any complications. However, surgical removal is required in some cases. Therefore, a delayed diagnosis or misdiagnosis could cause fatal complications for patients who need a surgical approach. We report a rare case of extraluminal migration of a foreign body to the deep cervical space. The foreign body (a fishbone) was removed by a surgical approach. With a literature review, we also propose an algorithm for the management of suspicious foreign bodies in the neck.

ABSTRACT

Purpose@#Croup is a clinical manifestation of coronavirus disease 2019 (COVID-19) in children. The Omicron variant of severe acute respiratory syndrome coronavirus 2 usually causes an upper respiratory tract infection. We investigated the differences between croups caused by COVID-19 and by other respiratory viruses (ORV). @*Methods@#We reviewed clinical characteristics, therapeutic measures, and the Westley Croup Score of children with croup who visited the emergency department of Gyeongsang National University Hospital from January 1 through April 7, 2022. According to the laboratory-confirmed viruses, they were divided into 2 groups: COVID-19 and ORV. Between the 2 groups, we compared the abovementioned features. Moderate-to-severe croup was defined by a Westley Croup Score of 3 or higher. @*Results@#A total of 20 children were diagnosed with croup caused by COVID-19 (n = 11; median age, 18 months) or by ORV (n = 9; 7 months). Median Westley Croup Score was higher in the COVID-19 group than in the ORV group (5.0 [range, 0-10.0] vs. 2.0 [1.0-5.0]; P = 0.031). Among the components of the scoring system, only stridor showed a significant difference (e.g., “stridor at rest”: COVID-19, 8 of 11 vs. ORV, 2 of 9; P = 0.046). Median C-reactive protein concentration was higher in the COVID-19 group (3.2 vs. 0.4 mg/L; P = 0.007). Severity of the COVID-19 group was marginally higher than that of the ORV group in terms of the median oxygen saturation (95% vs. 98%; P = 0.056) and the proportions of moderate-to-severe croup (9 of 11 vs. 3 of 9; P = 0.065) and application of high-flow nasal cannula (4 of 11 vs. 0 of 9; P = 0.094). @*Conclusion@#Croup caused by COVID-19 during the period of dominance of the Omicron variant outbreak might be more severe than croup caused by ORV.

ABSTRACT

Lobular capillary hemangioma (LCH) is a type of benign vascular tumor. It arises from vascular endothelial cells and contains capillaries arranged in a lobular pattern. In the head and neck, the most common presenting location of LCH is the lips, and presentation in the larynx is very rare. LCH might not be distinct from granuloma in macroscopic views. We report a 71-year-old female with LCH of the larynx that was totally resected via laryngeal microsurgery with a CO2 laser and briefly review the literature.

ABSTRACT

Chyle leakage from the neck, which usually occurs after iatrogenic injury of the thoracic or lymphatic duct, is an uncommon complication of head and neck surgeries, which include neck dissection or thyroidectomy. A small amount of chyle leakage can be treated with conservative approaches, such as nutritional limitation, somatostatin analogues, and wound compression. However, massive or uncontrolled chyle leakage requires surgical exploration of the wound and thoracic duct ligation via the chest or transabdominal thoracic duct embolization can be applied. Here, we report a case of intractable massive chyle leakage in a 78-year-old male after a left neck level V lymph node biopsy, which was not controlled after conservative management and explorative surgery. Various treatment approaches were attempted and successful management of chyle leakage was ultimately achieved by thoracic duct embolization.

ABSTRACT

Background and Objectives@#Pilomatricoma is a frequently diagnosed skin lesion of the head and neck that may often be misdiagnosed as other skin lesions. This study evaluated whether ultrasonography (USG) or computed tomography (CT) is the most helpful imaging modality for the accurate preoperative diagnosis of pilomatricoma in head and neck regions of children and adolescents.Subjects and Method A retrospective review was conducted for 59 patients with pilomatricoma under the age of 19 years. All cases were pathologically confirmed with pilomatricoma in the head or neck. @*Results@#Preoperative imaging examinations were performed with USG in six cases and with CT in nine cases. The accuracy of preoperative diagnosis was compared between three groups: 1) with clinical findings only, 2) with USG, and 3) with CT. The correct preoperative diagnosis was made in 18 (30.5%) of the total of 59 cases. Using only clinical findings, 10 (22.7%) out of 44 patients were diagnosed as pilomatricoma. With the addition of USG, pilomatricoma was diagnosed in 1 (16.7%) out of six cases, whereas with the addition of CT, 7 (77.8%) out of 9 cases (77.8%) were diagnosed correctly. Preoperative diagnosis of pilomatricoma with CT imaging was more accurate than clinical findings only (vs. CT; odds ratio [OR]=11.900, 95% confidence interval [CI] 2.126-66.615; p=0.001) or USG (vs. CT; OR=17.500, 95% CI 1.223-250.357; p=0.020). @*Conclusion@#In the preoperative diagnosis of pilomatricoma, imaging modalities such as CT and USG are helpful, with CT offering higher diagnostic accuracy and USG procedural benefits in younger children.

ABSTRACT

Liposarcomas are common mesenchymal malignant tumors arising from adipose tissue. Although liposarcomas are the most frequent type of soft tissue sarcomas, accounting for approximately 20% of all soft tissue sarcomas, they are rare in the head and neck, particularly in the oral cavity. Oral liposarcomas have been reported to occur mainly on the buccal mucosa, with other sites including the floor of the mouth, tongue, palate, and mandible. This report describes a 76-yearold male patient with an atypical lipomatous tumor/well-differentiated liposarcoma of the tongue that underwent surgical excision. This report also reviews published data on these rare tumors.

ABSTRACT

Anterior neck mass is a common symptom that is seen in otolaryngology surgery centers. Common types include thyroid tumor and thyroglossal duct cyst. In an elderly patient, a differentiated thyroid carcinoma should be suspected especially if it moves when swallowing. We encountered a typical presentation of a solitary thyroid nodule-like mass without pulsation in an 81-year-old female. We presented a rare diagnosis of pulsatile anterior neck swelling in which a high-riding subclavian artery should be considered as a differential diagnosis. Ultrasonography, Doppler scan, and contrast CT scan revealed that the neck mass corresponds to the high-riding subclavian artery. Therefore, ultrasonography is essential to detect any vascular lesion prior to biopsy or fine needle aspiration cytology as to avoid catastrophic hemorrhage.

ABSTRACT

Primary thyroid lymphoma is a rare malignancy that can grow rapidly and compress the airway. In such cases, a tracheostomy or thyroidectomy is generally required. Here, we report a case of a 76-year-old woman diagnosed with primary thyroid diffuse large B-cell lymphoma (DLBL), with dyspnea attributed to tracheal compression by the enlarged thyroid. The patient’s poor general condition meant that thyroidectomy was considered challenging. Therefore, a temporary endotracheal silicone stent was successfully inserted to maintain the airway, as tracheal stenting has been shown to be an effective treatment for both benign and malignant obstructive airway diseases. We conclude that, in patients with primary thyroid DLBL who present with airway compression but are not eligible for surgery, tracheal stent insertion can maintain the airway and allow time for chemotherapy to be administered.

ABSTRACT

BACKGROUND: Clear and proper feedback is necessary to decrease the gap between knowledge and practice. Feedback can improve clinical competence of medical students up to expertise level.METHODS: A total of 180 4th-year students of Daegu-Kyungbuk consortium area participated in the scheduled feedback program of clinical performance examination on August 26th in 2017. Among them, 167 students filled out the questionnaire on helpfulness of the direct observation and feedback of faculty and standardized patient (SP), helpfulness for history taking (Hx), physical examination (PE), and patient-physician interaction (PPI), and any change of clinical competence and clinical reasoning of the students preand post-feedback. All the responses were measured on 5-point Likert scale.RESULTS: Among the total students, 88.6% responded that direct feedback at the practice is helpful, particularly 95.2% of faculty and 76.6% of SP. A 37.3% answered that it was helpful for all the categories of feedback, but only 25.3% for PE and 24.7% for Hx. A 56.3% responded that feedback is helpful for both disease questions and counseling practice. Mean score of self-assessment by the students increased from 2.52 to 3.36 for Hx, 2.30 to 3.24 for PE, 2.46 to 3.33 for clinical reasoning, 2.84 to 3.59 for PPI, and 2.44 to 3.28 for overall competence. And all these differences were found to be statistically significant (P <0.001)CONCLUSION: A majority of students responded that the direct feedback from faculty and SP was helpful at the clinical practice of Hx, PE, and PPI, and increased the level of clinical competence.

ABSTRACT

BACKGROUND AND OBJECTIVES@#This study examined the expressions of p16 and the programmed cell death 1 ligand (PD-L1) in patients with oropharyngeal cancer (OPC) treated with radiotherapy (RT) to identify the correlation between p16 and PD-L1 expression, and to examine the prognostic significance of these markers for OPC patients receiving RT.SUBJECTS AND METHOD: Forty-eight OPC patients diagnosed and treated at a tertiary referral hospital were enrolled in this retrospective analysis. Patients were initially treated with RT or chemoradiotherapy (CRT) with curative intent and completed the planned schedule. Expression of p16 and PD-L1 by primary tumors was evaluated by immunohistochemistry, and results were interpreted separately and dichotomized according to outcome analyses.@*RESULTS@#Of the 48 patients, 25 (52.1%) expressed p16 and 15 (31.3%) expressed PD-L1. Expression of these markers showed a mutual positive correlation (p=0.046). Positive PD-L1 expression was associated with poor complete remission (CR) rates after RT (p=0.040). Positive p16 expression was associated with better recurrence-free survival (RFS) (p=0.004) but not overall survival (OS) (p=0.192). PD-L1 expression showed no independent association with survival (p>0.05); however, PD-L1 expression tended toward poorer RFS, even in p16-positive individuals.@*CONCLUSION@#There was a positive correlation between the expression of p16 and PD-L1 in OPCs. PD-L1 expression was associated with poorer CR rates after RT or CRT. PD-L1 alone did not show an association with RFS or OS, but when combined with p16, it tended toward poorer RFS, even in p16-positive cases.

ABSTRACT

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to “surgical management of oral cancer” published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrandomized Studies) and AMSTAR (A Measurement Tool to Assess the Methodological Quality of Systematic Reviews). Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. Additional directives are provided as expert opinions and Delphi questionnaire when insufficient evidence existed. The Committee developed 68 evidence-based recommendations in 34 categories intended to assist clinicians and patients and counselors, and health policy-makers. Proper surgical treatment selection for oral cancer, which is directed by patient- and subsite-specific factors, remains the greatest predictor of successful treatment outcomes. These guidelines are intended for use in conjunction with the individual patient's treatment goals.

ABSTRACT

A 56-year-old female presented with clinical features of acute tonsillitis with subsequent cervical lymphadenitis. After taking empirical antibiotics for 1 week, the acute infection symptoms and signs were resolved. However, an asymmetric enlargement of the left palatine tonsil with ipsilateral neck swelling remained. Subsequent tonsillectomy and lymph node excisional biopsy were performed due to the possibility of malignancy. The patient was eventually diagnosed as malignant lymphoma according to pathological confirmation. We demonstrate the diagnostic challenges in such a rare case and emphasize the importance of differentiating malignant lymphoma from an atypically presenting acute infectious disease.

ABSTRACT

An intrathyroid thyroglossal duct cyst (TGDC) presented as an anterior neck mass in a 62-year-old male without history of prior thyroid disease or infection. This cyst was clinically indistinguishable from a thyroid nodule. In addition to that, fine needle aspiration cytology revealed normal–looking squamous cells. Diagnosis, work-up, management approach, and treatment of intrathyroid TGDC are discussed as well as distinguishing features between intrathyrod TGDC with tract and without tract. This is the very rare case of intrathyroid TGDC in Korean population and the possibility of intrathyroid TGDC should remain in the differential diagnosis of thyroid nodule.

ABSTRACT

Tuberculosis of the retropharynx is extremely rare. The diagnosis is frequently delayed because of its anatomical location and atypical symptom. It would be crucial to consider tuberculosis infection as a possible source of abscess and should be mindful about the tests to diagnose it. We experienced a 23-year-old man with retropharyngeal abscess caused by tuberculosis presenting hypernasality and hoarseness in the throat. In this article, we reviewed the etiology, diagnosis, and treatment of this case, with a review of literatures.

ABSTRACT

OBJECTIVES: Our school introduced a new curriculum based on faculty-directed, intensive, small-group teaching of clinical skills in the third-year medical students. To examine its effects, we compared the mean scores on an OSCE between the third- and fourth-year medical students. METHODS: Third- and fourth-year students did rotations at the same five OSCE stations. They then completed a brief self-reporting questionnaire survey to examine the degree of satisfaction with new curriculum in the third-year students and clinical practice in the fourth-year students, as well as their perception of confidence and preparedness. We analyzed the OSCE data obtained from 158 students, 133 of whom also completed the questionnaire. RESULTS: Mean OSCE scores on the breast examination and wet smear stations were significantly higher in the third-year group (P < 0.001). But mean OSCE scores of motor-sensory examination and lumbar puncture were significantly higher in the fourth-year group (P < 0.05). The mean OSCE scores had no significant correlation with satisfaction. In addition, the self-ratings of confidence had a high degree of correlation with satisfaction with new curriculum (r = 0.673) and clinical practice (r = 0.692). Furthermore, there was a moderate degree of correlation between satisfaction and preparedness in both groups (r = 0.403 and 0.449). CONCLUSIONS: There is no significant difference in the effect on the degree of clinical performance and confidence between an intensive-small group teaching and a 1-year clinical practice. If combined, intensive small group teaching and clinical practice would be useful to improve the degree of ability and confidence in medical students.

ABSTRACT

Follicular thyroid carcinoma is the second most common form of thyroid cancer. It accounts for 10 percent of all thyroid cancer, and is found three times more frequently in men than in woman. It is well known that follicular thyroid carcinoma usually occurs in regions where it is hard for people to intake iodine. Most follicular thyroid carcinomas occur asymptomatically but occasionally reveal as masses in the thyroid nodules. The occurence of metastasis of follicular thyroid cancer in the lymph node is less than 10%, which is relatively low compared to that of papillary cancer. Follicular carcinomas are metastasized hematogenously and are common in the bone, liver, lung and brain. It is especially rare for metastatic follicular thyroid cancer to be diagnosed as renal tumor. We recently experienced and further investigated a case of follicular thyroid carcinoma that metastasised to the kidney in a 57-year-old woman, who had had abdominal distension. We report this case with a review of the reference.

ABSTRACT

BACKGROUND/AIMS: Gastric cancer (GC) is the second most common cancer in Korea and the most common in men in the south of the country. We investigated the incidence of synchronous GC in patients with head and neck squamous cell carcinoma (HNSCC) in the southern part of Korea. MATERIALS AND METHODS: We retrospectively reviewed the medical records of HNSCC patients treated between 2011 and 2014. In patients with synchronous GC, evaluation included a history of smoking and alcohol consumption, endoscopic findings, Campylobacter-like organism (CLO) test, and immunohistochemical analysis of preserved HNSCC tissues. RESULTS: Analysis of the records of 153 HNSCC patients revealed tumors of the larynx in 56 patients (36.6%), of the pharynx in 74 patients (48.4%), and tumors at other locations in 23 patients (15.0%). The mean age of patients was 66.0 years, and the men:women ratio was 8:1. Synchronous cancers were detected in 12 patients. We observed esophageal squamous cell carcinoma (SCC) in five patients (3.3%), and gastric adenocarcinoma in seven patients (4.6%). Synchronous GC was detected in patients with laryngeal SCC. All cases of GC were classified as early GC. CONCLUSIONS: Synchronous GC was as frequent as esophageal SCC in patients with HNSCC, and all cases of GC were observed to be early stage cancers in this study. Thorough endoscopic examination should be performed in patients with laryngeal cancer to detect the presence of synchronous GC.
