Bronchioloalveolar carcinoma may present with a variety of radiographic and clinical appearances. The authors reviewed the radiographs of 17 patients with pathologically proven bronchioloalveolar carcinoma, retrospectively. Seven cases were of the localized form. Among the seven five showed a localized mass and two showed localized consolidation. Ten cases were of the diffuse form. Among the ten, three showed diffuse nodules, two showed diffuse consolidation, and five showed a combined pattern of nodules and consolidations. Progression of disease was observed in 9 patients. In these cases, localized forms progressed to a diffuse forms and nodular patterns progressed to a consolidation pattern. Seven cases of the diffuse form were given antituberculous medications on hospital admission. In summary, bronchioloalveolar carcinoma has varied radiographic patterns, and often mimicks other pulmonary diseases such as pulmonary tuberculosis.

PURPOSE: The aim of this retrospective study is to analyze the relationship between local factors and survival rate of dental implant which had been installed and restored in Seoul Veterans Hospital dental center for past 10 years. And when the relationship is found out, it could be helpful to predict the prognosis of dental implants. MATERIALS AND METHODS: A retrospective study of patients receiving root-shaped screw-type dental implants placed from January 2000 to December 2009 was conducted. 6385 implants were placed in 3755 patients. The following data were collected from the dental records and radiographs: patient's age, gender, implant type and surface, length, diameter, location of implant placement, bone quality, prosthesis type. The correlations between these data and survival rate were analyzed. Statistical analysis was performed with the use of Kaplan-Meier analysis, Chi-square test and odds ratio. RESULTS: In all, 6385 implants were placed in 3755 patients (3120 male, 635 female; mean age 65 +/- 10.58 years). 108 implants failed and the cumulative survival rate was 96.33%. There were significant differences in age, implant type and surface, length, location and prosthesis type (P<.05). No significant differences were found in relation to the following factors: gender, diameter and bone quality (P>.05). CONCLUSION: Related factors such as age, implant type, length, location and prosthesis type had a significant effect on the implant survival.

Pulmonary histiocytosis X is a rare granulomatous disorder of unknown etiology that alters the interstitium of the lung. When confined to the lung, it is known as primary pulmonary histiocytosis X or eosinophilic granuloma of the lung. The chest radiograph shows characteristic nodular, reticular, and cystic abnormalities, which are most apparent in the upper and middle lung zones, but spare the costophrenic angles, The CT demonstrates innumerable small cysts with thin walls, and fine nodules. Recently we experienced pathologically proven primary pulmonary histiocystosis X in 35 years old male patients who had recurrent pneumothorax.

Trigeminal neuropathy commonly presents prolonged disorder of sensation in the distribution of the fifth cranial nerve of unilateral side and involves more than one division. We are reporting a case of a pure trigeminal motor neuropathy without sensory symptoms. 38-year-old man suffered from a mild common cold followed by progressive weakness and wasting of right masticatory muscles without pain or sensory change. Neurological examination revealed sunken cheek and temple area with weakness of the masticatory muscles and normal sensation of the face and normal taste. And all other cranial nerve were intact. Electrophysiological study revealed abnormal spontaneous activities with no voluntary motor unit potentials from the right temporalis and masseter muscles. The masseter reflex examination elicited by reflex hammer stimulation showed very small amplitudes from the right side. Trigeminal evoked potential, brainstem evoked potential and electrophysiological trigeminal blink reflex were normal. The imaging studies of the brain(CT and MRI) demonstrated atrophy of the right trigeminal motor nerve innervated muscles suggesting a pure trigeminal motor neuropathy without sensory involvement. We suspected a viral infection as the cause of their condition.

PURPOSE: To evaluate the efficiency of a surgical method using original breaks to drain subretinal fluid without using retinotomy and perfluorocarbon liquid for patients with rhegmatogenous retinal detachment (RRD). METHODS: A retrospective chart review comparing 41 eyes of 41 patients who received vitrectomy, and used original breaks to drain subretinal fluid without using perfluorocarbon liquid, and 40 eyes of 40 patients who received vitrectomy using perfluorocarbon liquid for simple RRD between February 2014 and December 2017 was conducted. All patients were followed for a minimum of 6 months after surgery. RESULTS: The primary anatomical success percentages were 97.6% and 97.5% for groups that did not and did use perfluorocarbon liquid, respectively. Retinal detachment recurred in one eye from both groups. The final success percentage was 100%. The preoperative mean logMAR best-corrected visual acuity (BCVA) of 0.87 ± 0.80 improved to 0.30 ± 0.30 at postoperative 6 months for the group that did not use perfluorocarbon liquid, while it improved from 0.86 ± 0.71 to 0.42 ± 0.52 for the group that did use perfluorocarbon liquid. Both groups showed significant BCVA improvement (p < 0.01). There was no significant difference in the incidence of complications caused by the use of perfluorocarbon liquid. CONCLUSIONS: Using original breaks to drain subretinal fluid without perfluorocarbon liquid in cases with RRD may be an effective and safe surgical technique for functional and anatomical recovery without serious complications.

Purpose: To evaluate changes in central macular thickness (CMT) and subfoveal choroidal thickness (SFCT) after phacovitrectomy over a 2-year period in idiopathic epiretinal membrane (ERM) patients. Methods: The records of 52 idiopathic ERM patients (52 eyes) who underwent phacovitrectomy, without recurrence of the condition over a 2-year follow-up period, were reviewed retrospectively. Changes in CMT and SFCT, as measured by optical coherence tomography, were analyzed and compared with those of a normal control group over a 2-year period. Results: The mean preoperative CMT and SFCT were 425.67 ± 84.67 and 257.56 ± 90.13 μm, respectively. Postoperative CMT was reduced significantly to 372.17 ± 45.26 μm at 1 year and 363.15 ± 47.35 μm at 2 years (p < 0.001). SFCT at 1 and 2 years postoperatively was significantly reduced to 238.85 ± 84.85 and 230.31 ± 87.95 μm, respectively (p < 0.001). In the control group, there was no significant change in CMT; however, the SFCT decreased by 11.09 ± 22.36 μm during the 2-year follow-up (p = 0.007). In contrast, in the patient group, CMT and SFCT decreased by 62.52 ± 71.45 and 27.25 ± 41.97 μm, respectively, showing a significant difference from the control group (p < 0.001 and p = 0.043, respectively). Both before surgery and at 1 year postoperatively, the thinner the CMT, the better the best-corrected visual acuity (BCVA) (p = 0.010 and p = 0.018, respectively). A better postoperative BCVA at 2 years was associated with a thinner CMT and better BCVA before surgery (p < 0.001 and p < 0.001, respectively). Conclusions Following a phacovitrectomy procedure, ERM patients showed significant reductions in both the CMT and SFCT at the 2-year follow-up.
