PURPOSE: Studies reported controversial results about prognosis of root resection with 0%-38% failure rate. The purpose of this study is to consider clinical efficacy of root resection. MATERIALS AND METHODS: This study reported three cases of root resection which were performed on different sites. In first case, lower right first molar showed pus discharge and 7 mm of probing pocket depth. It was diagnosed as fracture of mesial root. Hemisection of mesial root was performed In second case, upper right first molar showed severe bone loss on disto-buccal root and 7 mm of probing pocket. Resection of disto-buccal root was performed In third case, lower left second molar showed severe bone loss on distal root including apex and 15mm of probing pocket depth. Hemisection of distal root was performed. RESULT: In these three cases of root resection, compromised molars were treated successfully and conserved. CONCLUSION: Root resection is a successful procedure treating compromised multi-rooted teeth and conserving teeth when proper case selection is performed.

2.A Case of Long-term Residual Cholesteatoma.
Korean Journal of Otolaryngology - Head and Neck Surgery 1997;40(5):786-790
The estimated incidence of recurrent or residual cholesteatoma requiring revision mastoid surgery ranges from 2% to 10% in canal wall down mastoidectomy. The causes of failure of mastoidectomy include recurrent cholesteatoma, suppuration in unexentrated cells, and mechanical factors promoting retention of debris within the mastoid cavity. The authors have experienced a case of long-term residual cholesteatoma, without connection to the previous radical mastoidectomized cavity, which showing subscalp fistula and extradural granulation with continuous purulent discharge. So we report with a review of literature.

OBJECTIVE: The aim of this study is to assess the significance of an apparent diffusion coefficient(ADC) study for diagnosis of ventriculitis. METHODS: Seven patients with ventriculitis were enrolled in this study. Diffusion-weighted(DW) magnetic resonance images(MRI) and ADC maps in the dependent intraventricular collection, periventricular white matter and non-dependent cerebrospinal fluid(CSF) were obtained. The images and ADC data from the different lesions were compared. RESULTS: The DW MRI showed marked hyperintensity in the purulent pus lesion, and the corresponding ADC maps revealed prominent hypointensity and restricted ADC values compared with the non-dependent CSF and normal white matter. CONCLUSION: The decreased ADC value and increased signal intensity of the dependent intraventricular fluid on the DW MRI show restricted water diffusion in the purulent fluid, which is indicative of a pyogenic ventriculitis diagnosis.

BACKGROUND AND OBJECTIVES: There have been many studies concerning histologic changes and effectiveness of specific treatment in the experimentally induced sinusitis model, but there are few studies about natural course of paranasal sinusitis. This study aimed to analyze the natural course of sinusitis and the influence of stress on the natural disease course. MATERIALS AND METHOD: Natural ostia of 120 rabbits were occluded and reopened at 10 days after occlusion. Rabbits were divided into six groups according to duration from reopening to sacrifice. Each group was sacrificed at 1, 4, 8, 12, 19, 26 days after reopening of the natural ostium. Each group was divided into a control and stress subgroups. Radiologic, gross and histologic findings were analyzed. RESULTS: Percentage of rabbits showing partial or total haziness was highest at 3 days after reopening in the control subgroup and at 11 days in the stress subgroup. Percentage of the rabbits showing moderate or severe amount of pus in the sinus on gross examination was highest at 4 days in both subgroups. Degree of epithelial loss was most severe at 4 days in both subgroups. Subepithelial thickness was largest and inflammatory cell infiltrations were most severe at 8 days in both subgroups. Although there was a lack of statistical significance, stress subgroups showed more severe gross, radiologic, and histologic findings than those of control subgroups. CONCLUSION: This study shows that maxillary sinusitis is induced by natural ostium occlusion only and is improved with time without any treatment, and that stress might influence the severity of maxillary sinusitis.

The authors describe a case of tuberculous abscess of the cerebellum that originating probably from pulmonary lesion. The development of such a lesion indicates a persistence of infection and an immunological breakdown which may party have been due to unsatisfactory chemotherapy and protein malnutrition. Tuberculous brain abscess, an encapsulated collection of pus containing viable tubercle bacilli, is quite rare and it is different from tuberculoma in several points. Only five cases of tuberculous abscess have been fully documented and bacteriologically confirmed. The clinical, laboratory, and histopathological findings of those reported cases and the author's have been discussed.

The most common cause of chronic cutaneous sinus tract in the face and neck is chronically draining dental infection. The diagnosis is easily confirmed by dental examination and dental roentgenogram of the involved area, but this disease is frequently misdiagnosed and incorrectly treated in dermatologic department. We report four cases of cutaneous sinus tract of dental origin. First patient had a painful nodule with chronically draining pus and a dimple on the left cheek. Second patient had a dimple with draining bloody fluid on the right chin. Third patient had a pea-sized papule with draining serous fluid on the left chin. Fourth patient had a fluctuant erythematous plaque with draining pus and a dimple on the left buccal area. In all four patients radiologic examination of the maxillary and mandibular regions demonstrated radioluency at the apex of tooth consistent with periapical abscess.

Traumatic rupture of the corpus cavernosum of the penis is rare and has been reported infrequently. We experienced 4 cases of penile fracture for recent 2 years. They occurred during coitus(1 case), masturbation(2 cases), and through blunt trauma(1 case). The former 3 cases were treated with immediate surgical intervention about 12 hours after injury. When the last case patient visited hospital 5 days after injury, the penile abscess treated immediately with surgical intervention had developed. Surgery consisted of complete evacuation of the hematoma or pus and repairing of the tear at the tunica albuginea. The results were excellent, with complete early recovery of erectile function. Delayed wound healing was observed only in a patient who underwent surgery about 5 days after injury, but this did not cause any complication afterward. In our experiences, immediate surgical treatment is recommended in patients with fracture of the penis.

STUDY DESIGN: Infectious spondylitis patients were classified according to their cause in pyogenic and tuberculous and compared by each. SUMMARY OF LITERATURE REVIEW: Tuberculous spondylitis shows chronic clinical course and disc space sparing with much pus formation in radiologic finding compared to pyogenic spondylits. PURPOSE: To compare pyogenic and tuberculous spondylitis in clinical, radiological, pathological difference for appropriate management of infectious spondylitis. MATERIALS AND METHODS: We reviewed sixty two cases of infectious spondylitis confirmed by culture and pathologic findings of specimens which obtained by surgical method at the orthopaedic department of the Dong-A university hospital between June 1990 and November 1998. RESULTS: There were 18 cases of pyogenic and 44 cases of tuberculous spondylitis, and combined infection case was absent. Average period between beginning of symptom and diagnosis was 6.4 months in pyogenic spondylitis(4-11 months), 3.9 months in tuberculous spondylitis(3-39 months). The average number of affected vertebra was 2.3 in pyogenic spondylitis and 3.9 in tuberculous spondylitis. 6 cases of pyogenic spondylitis(33%) showed high fever(above 38degree C) which not presented in tuberculous spondylitis. We could not find considerable difference in leukocyte count, ESR, CRP level and simple radiologic finding, MRI finding between pyogenic and tuberculous spondylitis. CONCLUSIONS: In our study, most pyogenic spondylitis shows chronic and inactive feature, so clinical, radiological, laboratory findings are not appropriate guide to differentiate between pyogenic and tuberculous spondylitis. Culture growth of infecting agent and histologic examination are reliable and essential diagnostic method for pyogenic and tuberculous spondylitis.
