In the review of a series of 71 clavicle shaft fracture that were treated with open reduction and internal fixation, we tried a direct comparison between two fixation modes, that is, the fixation with plate and screws (54 cases) and the intramedullary nailing with Knowles pin (17 cases). The average time to healing was not significantly different between the two group; 10.8 weeks after the plating and 11.7 weeks with Knowles pinning. The rate of successful healing within four months after the surgery were also high in both groups: one delayed union and one nonunion in the plate group, and one delayed union in the Knowles pin group. There was one loosening in the Knowles pin group, which needed reoperation. Intramedullary fixation has several advantages compared with fixation with a plate and screws. It can be performed through a shorter incision: less dissection of soft tissue is needed: and, after healing, the pin is easily removed through a small incision under local anesthesia.

2.Maxillary IARPD, mandibular fixed implant supported prostheses in patient with crossed occlusion: a case report
The Journal of Korean Academy of Prosthodontics 2025;63(1):40-49
The crossed occlusion is unstable, and for the treatment of such occlusal conditions, it is recommended to form a balance of occlusal force between the arch in contact with occlusal contact, to secure stable vertical support by symmetrically placing the implants in the posterior area, and it is necessary to improve the distorted occlusal plane, to have a regular check-up and to check whether the occlusal conditions are maintained stably after treatment. In this case, in order to resolve unstable occlusal condition in patient with crossed occlusion, the existing occlusal vertical dimension was maintained at the state of wearing the dentures, and the implant placement positions were planned based on the diagnostic waxup, and then the implants were placed using a surgical guides, and after the temporary prostheses stage, the final fixed prostheses were fabricated by incorporating the temporary prostheses form adapted by the patient to develop a stable vertical support, and finally the anterior maxillary region was restored with implant-supported removable partial denture. In this case, the patient adapted well without discomfort during the four-month follow-up and satisfactory aesthetic and functional clinical results were obtained, leading to this report.

Congenital middle ear cholesteatoma is a keratinizing squamous epithelial cyst that classically presents as a white "pearl" in either the anterosuperior or posterosuperior quadrants behind an intact tympanic membrane. The presenting features of congenital cholesteatoma depend upon the initial site of the disease. The most common presentation of this disease is a conductive hearing loss or a facial palsy of gradual onset. Other presentations include incapacitating vertigo with nystagmus, a feeling of fullness in the ear, frequent otalgia, an abnormal eardrum noted at physical examination for an unrelated condition and meningitis. Recently, we experienced a case of congenital cholesteatoma that was presented as a post-auricular fistula. In considering the management of such a fistula, it would be important to recognize the possibility that the disease may present in this way.

Pilomatricomas are rare, usually benign and solitary, asymptomatic, calcifying tumors of the hair matrix cell, which mostly appear in the first and second decade of life. However, they may occur in adulthood. The most prevalent sites of pilomatricomas in children are the head and neck but they may occur anywhere. The typical presentation is a firm, slowly enlarging, freely mobile, well-circumscribed subcutaneous nodule, measuring 0.5 to 3 cm in diameter. The tumors are generally solitary, often adherent to overlying skin. Multiple pilomatricoma is relatively rare. Spontaneous regression is never observed, complete surgical excision is a treatment of choice. We present two cases of pilomatricoma arising from the right posterior auricle and the left posterior neck, which were treated with simple excision.

BACKGROUND: Low bone mineral density (BMD) increases fracture risk. Anemia is highly prevalent. Some studies suggested that anemia is an independent risk factor for osteoporosis. The aim of this study was to evaluate the association between hemoglobin (Hb) level and BMD in Korean adults. METHODS: This study was based on data from the Korea National Health and Nutrition Examination Survey 2008 to 2011. Propensity score-matching was performed to establish a dataset for analysis. Regression analyses were used to evaluate the association between Hb and BMD. Mean BMD scores were compared between normal and anemia groups, and among normal, anemia with low ferritin, and anemia without low ferritin groups. RESULTS: There were partial positive associations between Hb and BMD in men, but negative associations in women. The normal group had lower mean BMD scores than the anemia group in men. However, the anemia group had higher whole-body and lumbar-spine BMD scores than the normal group in women. In a comparison of the three groups, the anemia without low ferritin group had the lowest all-site BMD scores in men and women. However, the anemia with low ferritin group had the highest all-site BMD scores in women. In postmenopausal women, the anemia without low ferritin group had the lowest all-site BMD scores. In premenopausal women, the anemia with low ferritin group had the highest whole-body BMD scores. CONCLUSIONS: This study found that Hb and anemia status were associated with BMD scores. However, the associations were different according to sex. This may be due to the etiology of anemia or low Hb levels.

Metronidazole-induced encephalopathy is a very rare complication of the long standing use of metronidazole. The encephalopathy is bilateral and symmetric in nature. We report on the magnetic resonance imaging (MRI) and clinical course of metronidazole-induced encephalopathy in a 60-year-old female with a persistent anaerobic brain abscess after draining of the abscess. After 3 months of metronidazole administration, the patient complained of dysarthria, tingling sense of all extremities, and left hemiparesis. MRI revealed symmetric hyperintensity lesions in medulla, pons, dentate nuclei of cerebellum, and splenium of corpus callosum, all of which represent typical findings of metronidazole-induced encephalopathy. In addition, asymmetric lesions in midbrain, thalamus, putamen and cerebral subcortical white matter were noted. The patient recovered after discontinuation of metronidazole and the remaining abscess was successfully treated with meropenem and levofloxacine.
