  • A benign metastasizing pulmonary leiomyomatosis(BMPL) is a rare and uncommon variety of leiomyoma. BML affects middle-aged women who had a previous hysterectomy due to a histologically benign appearing leiomyoma. BMPL is characterized by asymptomatic multiple smooth muscle nodules with a less aggressive course than a leiomyosarcoma. A 45-year-old woman who had a hysterectomy for a uterine leiomyoma 4 years prior to this study presented with multiple variable-sized lung nodule. A percutaneous needle biopsy confirmed the benign metastasizing pulmonary leiomyomatosis. Here, we present this case with a review of the relevant literatures.

  • Objective: This clinical study was performed with a female patient to evaluate the effects of combined Eastern-Western medicine treatment on benign paroxysmal positional vertigo after acute vestibular neuritis.Method: We used acupuncture, herbal medication, Western medication, fluid therapy, and the canalith repositioning maneuver to treat a female patient suffering from dizzy spells. The vertigo scale was checked to assess any improvement in symptoms.Results: The patient had originally recovered from acute vestibular neuritis, but after the first discharge, she came down with benign paroxysmal positional vertigo and had to be rehospitalized. She eventually got better, however, and her score on the vertigo scale improved.Conclusion: This study demonstrates that combined Eastern-Western medicine treatment may be an effective option for treating benign paroxysmal positional vertigo after acute vestibular neuritis, despite the difficulty of the treatment in this case.

  • This study investigates open-source dynamic XSS filters used as security devices in web applications to account for the effectiveness of filters in protecting against XSS attacks. The experiment involves twelve representative filters, which are examined individually by placing them into the final output function of a custom-built single-input-form web application. To assess the effectiveness of the filters in their tasks of sanitizing XSS payloads and in preserving benign payloads, a black-box testing method is applied using an automated XSS testing framework. The result in working with malicious and benign payloads shows an important trade-off in the filters' tasks. Because the filters that only check for dangerous or safe elements, they seem to neglect to validate their values. As some safe values are mistreated as dangerous elements, their benign payload function is lost in the way. For the filters to be more effective, it is suggested that they should be able to validate the respective values of malicious and benign payloads; thus, minimizing the trade-off. This particular assessment of XSS filters provides important insight regarding the filters that can be used to mitigate threats, including the possible configurations to improve them in handling both malicious and benign payloads.

  • A 16-year-old male presented with pain in the right posterior mandible on chewing that had lasted for several months. The radiographic features of the lesion included a radiolucent-radiopaque mixed-density mass with a radiolucent rim attached to the root of the mandibular right first molar. The preliminary radiographic diagnosis was benign cementoblastoma, which was confirmed by histopathological examination following surgical excision. The lesion recurred 3 years after treatment; radiographically, it consisted of 3 round foci with mixed radiopacity, each with a radiolucent rim near the root of the mandibular right second premolar and the edentulous postoperative region. The lesion was diagnosed as recurrent benign cementoblastoma and a second surgery was scheduled. This report presented an unusual case of recurrent benign cementoblastoma following surgical excision and extraction of the involved tooth, along with a literature review on reported cases of recurrent benign cementoblastoma with a focus on its clinical features and the best treatment options.

  • Benign monomelic amyotrophy(BMA) is an uncommon cause of progressive mildly disabling atrophy and weakness of a limb. It predominantly affects the distal upper limb of young men. I present two men with BMA of the lower extremities. Although the disorder seemed clinically confined to a arm or leg, I confirmed by electromyography evidence of denervation in the other extremities. I reviewed the literatures and discuss the differential diagnosis. BMA is a diagnosis of exclusion that requires consideration in men with unilateral arm or leg atrophy and weakness.

  • Benign osteoblastoma is an uncommon primary bone tumor, extremely rare in calvarium. We present a case of a 25-year-old female with an osteoblastoma of parietal bone which was totally resected. The authors discussed the clinical presentation, radiographic finding, differential diagnosis and management of the benign calvarial osteoblastoma with a review of the literature.

  • Here presented six cases of benign tumors of the lung treated surgically between Dec. 1957 and Dec. 1983 in the Department of Thoracic Surgery, Seoul National University Hospital. They include four cases of hamartoma, one case of benign mesothelioma, and one case of Castlemans disease. The operative procedures are three cases of lobectomy, one case of segmentectomy, and two cases of mass excision. The operative results are excellent without complication.

  • Worm attacks can greatly distort network performance, and countering infections can exact a heavy toll on economic and technical resources. Worm modeling helps us to better understand the spread and propagation of worms through a network, and combining effective types of mitigation techniques helps prevent and mitigate the effects of worm attacks. In this paper, we propose a mathematical model which combines both dynamic quarantine and passive benign worms. This Passive Worm Dynamic Quarantine (PWDQ) model departs from previous models in that infected hosts will be recovered either by passive benign worms or quarantine measure. Computer simulation shows that the performance of our proposed model is significantly better than existing models, in terms of decreasing the number of infectious hosts and reducing the worm propagation speed.

  • The diagnostic accuracy of routine cytological preparations from effusions ranges from 60% to 70%. Immunohistochemical markers, especially tumor-associated antigens, have been successfully employed to increase diagnostic sensitivity in effusion cytology. However, more than two different antibodies in diagnosis of effusions are needed. In the view of prevalence of abnormalities of p53 gene in human malignancies we investigated the diagnostic usefulness of demonstration of p53 protein immunoreactivity in distinguishing benign changes versus malignant processes in effusions. p53 protein expression was studied immunohistochemically in 76 effusions(28 malignant and 48 benign) using anti-human p53 antibody p53 immunoreactivity was identified in 19 of 28(67.9%) malignant effusions. In contrast, no p53 immunoreactivity was observed in all benign effusions. A specificity of 100% and a sensitivity of 67.9% were observed. These results suggest that immunohistochemical detection of p53 protein seems to be helpful in distinguishing benign changes versus malignant processes in effusions, although its principal limitation is its relatively low sensitivity.
