Neuroendoscopic and microscopic transsphenoidal approaches have been widely used in the resection of nonfunctional pituitary adenomas. However, the clinical efficacy in neuroendoscopic and microscopic surgery is still controversial. AIM To explore the clinical efficacy of neuroendoscopic and microscopic transsphenoidal approach for resection of nonfunctional pituitary adenomas. METHODS We retrospectively analyzed 251 patients with nonfunctional pituitary adenomas;138 underwent neuroendoscopic surgery via transsphenoidal approach, and 113 underwent microscopic surgery via transsphenoidal approach between July 2010 and September 2015. All patients were followed up for > 6 mo. Gender, age, course of disease, tumor diameter, tumor location, and percentage of patients with headache, visual impairment, sexual dysfunction, and menstrual disorders were contrasted between the two groups to compare the difference of preoperative data. Cure rate, symptom improvement rate, recurrence rate, the postoperative hospital stay, operating time, intraoperative blood loss, and the incidence of postoperative complications were compared in order to evaluate the advantages and disadvantages of neuroendoscopic and microscopic surgery.RESULTS There was no significant difference in cure rate, symptom improvement rate, and recurrence rate between neuroendoscopy group and microscopy group (82.6% vs 85.8%, P > 0.05;90.6% vs 93.8%, P > 0.05;5.1% vs 9.7%, P > 0.05). In the neuroendoscopy group, the postoperative hospital stay was 8.4 ± 0.6 d;operating time was 167.2 ± 9.6 min;intraoperative blood loss was 83.4 ± 9.3 mL, and the rates of diabetes insipidus and electrolyte imbalance were 4.3% and 8.0%, respectively. The corresponding results in the microscopic group were 11.2 ± 0.6 d, 199.7 ± 9.3 min, 138.8 ± 13.6 mL, and 32.7% and 20.4%, respectively. There were significant differences in postoperative hospital stay, operating time, intraoperative blood loss, and the rates of diabetes insipidus and electrolyte imbalance between the two groups (P < 0.05). CONCLUSION Neuroendoscopic and microscopic transsphenoidal approaches have similar clinical efficacy for the resection of nonfunctional pituitary adenomas. Neuroendoscopic surgery reduces operating time, intraoperative bleeding, postoperative recovery, and complications.展开更多

But predictive biomarkers do not always work. When unsuccessful, they add cost, complexity, and time to drug development. This perspective describes phases 2 and 3 development methods that efficiently and adaptively check the ability of a biomarker to predict clinical outcomes. In the end, the biomarker is emphasized to the extent that it can actually predict.展开更多

Moreover, it has been recently proposed the existence of a distinct diagnostic subgroup of schizo-obsessive disorder. However, the further investigation of the OCS or OCD-schizophrenia diagnostic comorbidity presupposes the accurate clinical differential diagnosis of obsessions and compulsions from delusions and repetitive delusional behaviours, respectively. In turn, this could be facilitated by a careful comparative examination of the phenomenological features of typical obsessions/compulsions and delusions/repetitive delusional behaviours, respectively. Thiswas precisely the primary aim of the present investigation. Our examination included seven features of obsessions/delusions(source of origin and sense of ownership of the thought, conviction, consistency with one's belief-system, awareness of its inaccuracy, awareness of its symptomatic nature, resistance, and emotional impact) and five features of repetitive behaviours(aim of repetitive behaviours, awareness of their inappropriateness, awareness of their symptomatic nature, and their immediate effect on underlying thought, and their emotional impact). Several of these clinical features, if properly and empathically investigated, can help discriminate obsessions and compulsive rituals from delusions and delusional repetitive behaviours, respectively, in patients with schizophrenic disorders. We comment on the results of our examination as well as on those of another recent similar investigation. Moreover, we also address several still controversial issues, such as the nature of insight, the diagnostic status of poor insight in OCD, the conceptualization and differential diagnosis of compulsions from other categories of repetitive behaviours, as well as the diagnostic weight assigned to compulsions in contemporary psychiatric diagnostic systems. We stress the importance of the feature of mental reflexivity for understanding the nature of insight and the ambiguous diagnostic status of poor insight in OCD which may be either a marker of the chronicity of obsessions, or a marker of their delusionality. Furthermore, we criticize two major shortcomings of contemporary psychiatric diagnostic systems(DSM-IV, DSM-V, ICD-10) in their criteria or guidelines for the diagnosis of OCD or OCS: first, the diagnostic parity between obsessions and compulsions and, second, the inadequate conceptualization of compulsions. We argue that these shortcomings might artificially inflate the clinical prevalence of OC symptoms in the course of schizophrenic disorders. Still, contrary to a recent proposal, we do not exclude on purely a priori grounds the possibility of a concurrence of genuine obsessions along with delusions in patients with schizophrenia.展开更多

They represent less than 1% of thymic malignancies. They often present with an advanced disease and metastasize to regional lymph nodes and distant sites. They have a worse prognosis with a 5-year survival rate of 30%-50%, while thymomas are much less invasive and have a 5-year survival of approximately 78%. We report a rare form of clinical presentation of a thymic carcinoma in which the diagnosis of myasthenia gravis was the cornerstone of the diagnosis of cancer. Surgery is considered the salvage treatment when possible. Radiotherapy is a second choice of salvage treatment, when possible depending on its localization and relation to nearby structures such as vascular structures. Molecular target therapy is a more directed, more expensive but less toxic treatment. Further studies need to be carried out for its approval worldwide, outside clinical trials.展开更多

This research is to explore the clinical effect of primary total hip replacement (THA) via direct anterior approach (DAA) and posterolateral approach (PLA) in the treatment of femoral neck fracture. Methods: Retrospective analysis of 100 cases of elderly patients with femoral neck fracture who underwent total hip arthroplasty admitted to Tianyou Hospital affiliated to Wuhan University of Science and Technology from January 2019 to January 2022. 50 patients treated with DAA approach were included in the observation group, and 50 patients treated with PLA approach were included in the control group. The operation indexes, postoperative acetabular abduction angle and anteversion angle, hip joint function, Harris score and complications were compared between the two groups. Result: The length of incision in the observation group was shorter than that in the control group, and the amount of intraoperative bleeding and postoperative hospital stay were shorter than those in the control group (P < 0.05);There was a statistically significant difference between the two groups in the ratio of acetabular abduction angle and its safe zone, and the length difference of both lower limbs (P < 0.05), while there was no statistically significant difference between the two groups in the ratio of acetabular anteversion angle and its safe zone, eccentricity, and its recovery rate (P > 0.05);Harris score of hip joint: 6 months after operation, the anterior approach group was significantly higher than the posterolateral approach group (P < 0.05), and there was no statistical difference between the two groups 12 months after operation (P > 0.05);The total incidence of complications in the observation group was lower than that in the control group, with a statistically significant difference (P Conclusion: DAA and PLA approaches for total hip replacement can restore the hip joint structure of patients with femoral neck fractures and achieve good results, but DAA approach has greater advantages in early postoperative recovery, improvement of hip joint function, small surgical injury, high application value, so it is recommended.展开更多
