Impact of Different Evaluation Methods for Diagnostic Tasks in Panoramic Radiography

The aim of this study was to evaluate the observers’ diagnostic performance in panoramic radiography using monitor, tablet, X-ray image view box, and against window daylight as a visualization method in different diagnostic tasks. Thirty panoramic radiography were assessed by three calibrated observers for each visualization method, in standardized light conditions, concerning dental caries, widened periodontal ligament space, and periapical bone defects from the four first molars; mucosal thickening and retention cysts in maxillary sinus; and stylo-hyoid ligament calcification and atheroma. A five-point confidence scale was used. The standard-reference was performed by two experienced observers. Diagnostic values using window light were significantly lower for caries and periapical bone defect and retention cyst, stylo-hyoid ligament calcification detection (p<0.05). For atheroma detection, X-ray image view box, tablet, and widow light had lower accuracy than the evaluation on the monitor (p<0.05). Observer’s diagnostic performances are worsened using window light as an evaluation method for panoramic radiography for dental, sinus, and calcification disorders, while the monitor was the most reliable method.

Long-term broncocele anamnesis, triggered by typical carcinoid

The paper presents a case of a single bronchocele (bronchogenic retention cyst) caused by a typical carcinoid that was observed for a long time. During the initial complex examination, including computed tomography with intravenous contrast, fibrobronchoscopy, and immunological and bacteriological examinations of tuberculosis, there were no changes for the oncological and infectious nature. The changes were interpreted as the result of a postponed nonspecific inflammatory process. Most of them were monitored using chest X-ray and the changes were stable. After 15 years, a control chest X-ray revealed an increase in the size of the compaction in the lung and the appearance of a mass with calcification in the medial sections of the compaction zone. Additional examination, including computed tomography with biopsy, determined that the obstruction of the bronchus was caused by a neoplasm [according to histological examination (typical carcinoid)]. It should be noted that the initial detection of negative study results requires oncological alertness and periodic examinations in dynamics.

Epidermoid Cyst of Vocal Cord - A Rare Case Report

Vocal cord swellings are a commonly encountered clinical entity. However, Vocal cord cysts are rare. Also, these are mostly retention cysts caused by obstruction of a glandular duct. We hereby report a case of vocal cord cyst which was diagnosed as retention cyst clinically. However, on excision followed by histopathological examination a diagnosis of epidermoid cyst was made. This case is reported due to the finding of a very rare entity and also to re-emphasize the importance of histopathology as gold standard in examination of lesions. Key words: Vocal cord cyst, epidermoid cyst, Vocal cord swelling.

The frequency of maxillary sinus pathologic findings in cone-beam computed tomography images of patients candidate for dental implant treatment

Background. Maxillary sinus pathologic conditions increase the risk of complications during sinus augmentation surgeries in the posterior maxilla. The present study aimed to determine the frequencies of maxillary sinus pathologic findings on patients’ cone-beam computed tomography (CBCT) images to receive dental implants. Methods. In this descriptive/cross-sectional study, 140 CBCT images of patients who were candidates to receive dental implants were evaluated for the presence of maxillary sinus pathologic entities during 6 months, were divided into five categories: mucosal thickening of >5 mm, retention cyst, partial or complete opacification of the sinus, polypoidal mucosal thickening, and healthy patients. Age, gender, and dental status were evaluated in terms of relationship with the sinus pathologic findings. Absolute and relative frequencies were used to describe data. The chi-squared test was used to analyze the variables. Statistical significance was set at P<0.05. Results. The frequency of maxillary sinus pathologic entities on CBCT images was 63.5%. The pathologic conditions in descending frequency were as follows: mucosal thickening (31.4%), retention cyst (17.1%), partial or complete opacification of the sinus (9.3%), and polypoidal mucosal thickening (5.7%). The frequency of pathologic findings in the maxillary sinus was higher in the <46-year age group and subjects with partial edentulism; however, the differences were not significant. Conclusion. In the present study, the most frequent maxillary sinus pathologic entity was mucosal thickening. There was no relationship between age, sex, and dentition status and maxillary sinus pathologic findings.

RIGA FEDE DISEASE- AN UNUSUAL PRESENTATION

A 7-year-old female child came to hospital with history of swelling over left side of tongue from 10 days. Swelling was identied accidentally by her mother. There were no complaints per se from the patient. On examination there was 2x1cm smooth swelling over dorsal surface of the left side of tongue in anterior one-third. It was a rm swelling with well-dened margins. Magnetic Resonant Imaging of neck with contrast was done which showed a T1 Hypointense with T2 hyperintense peripherally enhancing lesion of the left genioglossus which was suggestive of Fibroma/Dermoid cyst/mucous retention cyst. Cyst was excised in toto under General Anaesthesia and sent for Histopathological examination which showed features of Riga Fede disease (Eosinophilic ulcer of the tongue). Patient was followed up for 3 months and no signs of recurrence were seen.

Unilateral tonsillar swelling: role and urgency of tonsillectomy

Unilateral tonsillar swelling is a fairly common presenting complaint in an Ear, Nose and Throat (ENT) department. It may or may not be associated with any other symptoms. Most of the time, the tonsil asymmetry is secondary to previous history of tonsillitis, quinsy, and tonsil stones. Other benign lesions to cause tonsil swelling may include a mucus retention cyst, lipoma, polyp or papilloma. Sometimes, it is the site of primary malignancy but in these situations, it is often associated with red flag symptoms like pain in the mouth, dysphagia, odynophagia, referred otalgia, weight loss, night sweating, haemoptysis, haematemesis, hoarseness or neck nodes. Most of the patients with suspected tonsillar malignancy have underlying risk factors like smoking and excessive alcohol intake. However, lately, the tonsil squamous cell carcinoma can be found in younger patients with no history of smoking or drinking as there is rising incidence of human papilloma virus related oropharyngeal malignancy. Sometimes, lymphoma may manifest as a tonsil enlargement. If, after detailed history and examination, there remains any doubt about the underlying cause of unilateral tonsil swelling then tonsillectomy should be considered for histological analysis. it is our practice to perform bilateral tonsillectomy in such cases. We present a case of unilateral tonsillar swelling and discuss its management.
