PURPOSE: To compare the diagnostic ability of undergraduate dental students to detect maxillary sinus abnormalities in panoramic radiographs (PR) and cone-beam computed tomography (CBCT). MATERIALS AND METHODS: This was a retrospective study based on the evaluation of PR and CBCT images. A pilot study was conducted to determine the number of students eligible to participate in the study. The images were evaluated by 2 students, and 280 maxillary sinuses were assessed using the following categories: normal, mucosal thickening, sinus polyp, antral pseudocyst, nonspecific opacification, periostitis, antrolith, and antrolith associated with mucosal thickening. The reference standard was established by the consensus of 2 oral radiologists based on the CBCT images. The kappa test, receiver operating characteristic curves, and 1-way analysis of variance with the Tukey-Kramer post-hoc test were employed. RESULTS: Intraobserver and interobserver reliability showed agreement ranging from substantial (0.809) to almost perfect (0.922). The agreement between the students' evaluations and the reference standard was reasonable (0.258) for PR and substantial (0.692) for CBCT. Comparisons of values of sensitivity, specificity, and accuracy showed that CBCT was significantly better (P<0.05). CONCLUSION: CBCT was better than PR for the detection of maxillary sinus abnormalities by dental students. However, CBCT should only be requested after a careful analysis of PR by students and more experienced professionals.

PURPOSE: An ingrown nail is common in military trainees who are exposed to highly demanding activities. Although the matrixectomy procedure has been the main treatment modality, several drawbacks may follow after the procedure, such as infection, periostitis, and continued pain that causes a delayed return to duty. This study examined the outcomes of a simple partial nail extraction with the hypothesis that this procedure may bring an earlier return to duty, lower the perioperative complications, and produce a comparable recurrence rate. MATERIALS AND METHODS: The medical records of patients who had surgical treatment for an ingrown nail in the authors' institution between April 2016 and December 2017 were reviewed retrospectively. Under the inclusion and exclusion criteria, 28 patients with a simple partial nail extraction (group A) and 29 patients with a partial nail extraction with matrixectomy (group B) were investigated. As the clinical outcome, the visual analogue scale (VAS) and satisfaction score, time to return to duty, complications, and recurrence rate were checked and compared between the groups. RESULTS: The VAS scores of group B were significantly higher during the first (p<0.001) and second (p=0.026) follow-up week than group A. The time to return to duty was shorter in group A (7.8 days) than group B (10.1 days), and this difference was significant (p<0.001). Group B had five patients with complications, whereas group A had none (p=0.028). No differences in the recurrence rate (p=0.197) and patient satisfaction (p=0.764) were found between the groups. CONCLUSION: In this study, simple partial nail extraction in military trainees resulted in lower postoperative pain, lower complication rates, and earlier return to duty than the procedure with matrixectomy. Military trainees are temporarily exposed to highly demanding activities. Thus, a satisfactory outcome would be expected with simple partial nail extraction without performing a radical procedure, such as a matrixectomy.

In prolonged chronic osteomyelitis, chronic inflammation and low-grade infections can result in new periosteal bone formation. Chronic osteomyelitis with proliferative periostitis (traditionally termed Garré's sclerosing osteomyelitis) mainly affects children and young adults. Here, we present two rare cases of an 11-year-old and a 12-year-old patient with suppurative chronic osteomyelitis with proliferative periostitis without any definitive infection source, such as dental caries or periodontitis. The source of infection was likely to be related to the development of a lower right third molar germ with follicular space widening. Management involved antibiotics and the removal of the third molar germ and surgical debridement. Disease remission and a normal appearance was observed at the six-month follow-up visit.

Pachydermoperiostosis (PDP) is a primary hypertrophic osteoarthropathy characterized by digital clubbing, pachydermia, and periostosis, which is inherited as an autosomal dominant or recessive trait. We report on a patient suffering from bilateral knee arthritis for 6 years who was newly diagnosed as PDP. PDP was confirmed by bilateral digital clubbing, hyperhidrosis, and cutis verticis gyrata, findings of pachydermatosis on the forehead and scalp, X-ray findings of proliferative periostitis. This case indicates that PDP is one of several possible rare diseases that should be considered in patients with undifferentiated arthritis.

Proliferative periostitis is a rare form of osteomyelitis that is characterized by new bone formation with periosteal reaction common causes of proliferative periostitis are dental caries, periodontitis, cysts, and trauma. While proliferative periostitis typically presents as a localized lesion, in this study, we describe an extensive form of proliferative periostitis involving the whole mandibular ramus and condyle. Because the radiographic findings were similar to osteogenic sarcoma, an accurate differential diagnosis was important for proper treatment.

Psoriatic onycho-pachydermo-periostitis (POPP) causes severe nail dystrophy, painful soft tissue swelling, and marked periosteal reaction of the involved distal phalanx. There are few reports of POPP involving the great toe. We report on 2 cases of POPP involving the fingertips. A 60-year-old woman presented with fusiform swelling of her right 4th fingertip with severe tenderness, and her fingernails and toenails had varying degrees of onycholysis. She had mixed multiple erosions and meta-epiphyseal periostitis at the distal phalanx of the right 4th finger but was treated successfully with methotrexate and cyclosporine. A 39-year-old woman presented with painful swelling of the left 2nd and 5th fingertip, psoriatic lesions on the knees and soles of the feet, and onycholysis without reactive periostitis of the left 2nd and 5th fingers. She was treated successfully with cyclosporine. Despite its rarity, POPP should be considered when diagnosing arthritic or infectious conditions affecting the distal interphalangeal joint.

Numerous causes of hypertrophic osteoarthropathy (HOA) have been reported. Commonly, secondary osteoarthropathy accompanies pulmonary diseases such as carcinoma of the lung, pleural tumors, lung abscesses, and bronchiectasis. However, HOA in inflammatory bowel disease is a rare complication. There are only a few reports of secondary HOA with Crohn's disease. Our purpose was to report another case of HOA in Crohn's disease. We describe a case of a 27-year-old man with underlying Crohn's disease presenting with 2 years of pain in multiple joints. Radiographic findings suggested HOA in extremities. We performed a conservative treatment including medication and rehabilitations. The patient's symptoms were much improved at the latest follow-up. Although numerous studies on HOA have been published, the pathogenesis of HOA is still unclear. Various treatment modalities were recommended but further studies to uncover the pathogenesis of HOA with Crohn's disease and to establish a treatment modality are needed.

Periostitis is one of the human diseases commonly encountered in archaeological samples. It is known to be an important health indicator for paleopathologists examining skeletal remains. In our recent study on a Joseon skeletal series (n=101), non-specific, primary periostitis was observed only in five individuals (#4, #29, #137, #175, and #290). Notably, there were no secondary periostitis-suggestive signs (e.g. syphilis), except for those caused by fractures (#33 and #41). As this is the inaugural Korean-skeletal-series report on periostitis, the results presented in these pages should prove significant to interested paleopathologists.

We describe the case of a 4-month-old male infant diagnosed with early congenital syphilis during evaluation of a left distal humerus fracture. This report emphasizes the importance of screening for syphilis among pregnant women and newborns, and is a reminder of the continued existence of congenital syphilis.
