Ligneous periodontitis (LP) is a rare periodontal disease in which plasminogen deficiency and fibrin deposition both play a part, resulting in characteristic gingival enlargement and periodontal breakdown. Recent data suggest that oxidant/antioxidant changes are significant in the pathology of oral diseases. This study examines the gingival histopathology in 2 cases with LP. To examine the antioxidant (AO) status, the activity of the major AOs glutathione (GSH), catalase (CAT), and glutathione S-transferase (GST) and the malondialdehyde (MDA) levels, a product of lipid peroxidation, were measured and compared with healthy control subjects. The histopathologic examination of the gingiva revealed subepithelial fibrin accumulation and irregular extensive downward proliferation of the epithelium. Biochemical analysis showed that the CAT, GST, and MDA levels were higher in LP patients than in the control subjects, and the GSH level was lower. Our preliminary findings show that in LP, the AO capacity of the gingiva changes or decreases and lipid peroxidation increases, which suggests that oxidative stress is involved in the pathology of the periodontal breakdown observed in this disease. 相似文献

A 14-year-old boy had a 1-month history of diplopia (due to a VI nerve palsy), motor ataxia and dizziness. Brain MRI showed
a 1.5-cm mass posterior to the pons. Histopathological examination of a biopsy specimen showed the lesion to be of viral origin.
After 3 months, the ataxia and dizziness had resolved and the MRI findings returned to normal. By 5 months the abducens paralysis
had also resolved. Viral encephalitis should be considered in the differential diagnosis of posterior fossa tumours.

The purpose of this case series was to evaluate menstrual suppression in sex assigned at birth female adolescents identifying as male or gender non-conforming. A retrospective chart review of four gender minority youth (GMY), age 14-17, was performed for gender identity history, type and success of menstrual suppression, method satisfaction, side effects and improvement in menstrual distress. Menstrual suppression was successful in three patients, one patient discontinued use due to side effects that caused an increase in gender dysphoria. Menstrual distress and bleeding pattern improved in the majority of GMY in this series but side effects, as well as contraindications, may limit their use. In conclusion, menstrual dysphoria can be life-threatening for GMY and it is important that clinicians consider menstrual suppression in GMY with menstrual dysphoria. This series emphasizes the importance of individualized treatment plans. 相似文献

We present the case of a 71-year-old woman with a 7-year history of a giant left atrial myxoma. The myxoma was attached to the atrial septum and occupied almost the entire left atrial cavity. The patient was hospitalized 4 times because of dyspnea on exertion, palpitations, fatigue, general asthenia, and weight loss. During prior hospitalizations, the patient had refused cardiac surgery. She developed several complications, including atrial fibrillation, mitral and tricuspid regurgitation, mesenteric embolism, pulmonary edema, and thrombotic stroke. We herein describe the natural history of left atrial myxoma in an elderly patient over a 7-year period. 相似文献

A case of an 18-year-old gardener who sustained an anterior–superior dislocation of the sternoclavicular joint while playing handball and falling on his right shoulder is presented. Non-surgical treatment failed, and the patient could willingly dislocate the right clavicle while abduction and external rotation of the arm. This painful condition was finally treated with surgical reconstruction of the sternoclavicular joint using gracilis tendon autograft and repair of the discus. Level of evidence Therapeutic study, case report and technical note, Level IV. 相似文献
