Objectives To analyze the risk factors for cardiovascular disease (CVD) in patients with chronic obstructive pulmonary disease (COPD) of different severities. Methods The study included 50 patients with mild-to-moderate COPD and 50 with severe-to-very severe COPD admitted between January 2014 and January 2016. Comorbidities were recorded on the basis of data obtained from medical charts and clinical evaluations. The Charlson comorbidity index was calculated, and the Hospital Anxiety and Depression Scale (HADS) score was determined in each subject. Results There were more prevalences of smoking, depression and dyslipidemia in the patients with mild-to-moderate COPD than those with severe-to-very severe COPD (all P<0.001). The prevalences of high blood pressure, diabetes mellitus, alcoholism, and chronic heart failure were not different significantly between the two groups. The Charlson comorbidity index and HADS scores were not different between the two groups. Conclusions Comorbidities are fairly common in COPD regardless of its severity. Certain risk factors for CVD, as smoking, dyslipidemia, and depression, appear to be more prevalent in patients with mild-to-moderate COPD.
ObjectivesTo explore the safety and efficacy of beta-blockers (BBs) in patients with chronic obstructive pulmonary disease (COPD) and its effect on prognosis. MethodsThe data of 366 patients with acute exacerbation of COPD in this department were analyzed retrospectively. The use rate and related events of BBs were evaluated, including comorbidity, indications, contraindications and related clinical indicators. ResultsOf the 366 patients, 156 (42.6%) had at least one indication of the use of BBs, but only 53 (34.0%) of these patients used BBs, and 61 patients (39.1%) had no contraindications but did not use BBs. At admission, 72 patients (19.7%) were treated with BBs, 177 (45.6%) with antiplatelet drugs, 145 (39.6%) with statins, and angiotensin converting enzyme inhibitor/angiotensin II receptor blocker was used in 168 (45.9%) patients. Twenty-five patients (6.8%) had ischemic heart disease during hospitalization. Fifty-seven patients (15.6%) had cardiovascular and cerebrovascular events during admission. The patients with cardiovascular and cerebrovascular events had longer hospitalization (P<0.01) and higher in-hospital mortality (P=0.02). ConclusionsPatients with COPD have a clear indication of BBs use, but the clinical use rate is still very low. Further research is needed to explore the prescription disorders of BBs in patients with COPD.
ObjectivesTo investigate the clinical and imaging characteristics of pleural effusion in patients with acute pulmonary embolism (APE).MethodsComputed tomographic pulmonary angiography (CTPA) scans and clinical data of suspected APE patients from January 2014 to December 2018 were analyzed.ResultsA total of 1024 suspected APE patients underwent CTPA examination in the imaging department of our hospital. Two hundred patients (19.5%) were diagnosed with APE. Imaging findings of pleural effusion were revealed in 70 cases (35.0%). The majority of APE patients without pleural effusion were males (82.3% vs. 64.3%, P<0.01), and the majority of APE patients with pleural effusion were females (35.7% vs. 17.7%, P<0.01). Most of the effusions were bilateral, small to moderate, with peripheral embolism (62.9%, P<0.05). Pulmonary consolidation, atelectasis and ground-glass opacity were common manifestations of CTPA. Compared with patients with simple pulmonary embolism, pulmonary embolism with pleural effusion was more common (62.9% and 33.8%, respectively, OR=3.279 and 95%CI 1.798 - 6.091, P<0.001). Diagnostic thoracic puncture was performed in 6 cases (8.6%). Pleural effusion was exudate in these 6 patients, with normal blood sugar and neutrophils predominated.ConclusionsAbout one third of APE patients are associated with pleural effusion, which most presented with small and bilateral pleural effusions. The main embolism associated with pleural effusion is peripheral embolism. There is a significant correlation between pulmonary consolidation and pleural effusion. Pleural effusion is mostly exudate and neutrophils often predominate.
ObjectiveTo explore the clinical features and EEG features of gelastic seizures, and analyze its value of lateral localization of epileptogenic area. MethodsAll patients with gelastic seizures admitted to the Sanbo Brain Hospital of Capital Medical University between January 2014 and December 2023 were reviewed and analyzed for history, symptomatology, imaging, electroencephalographic features and surgical protocols in patients who met the inclusion criteria and were followed up for at least 1 year, and surgical efficacy was assessed by using the Engel grading. ResultsA total of 51 patients with gelastic seizures were included, there were 32 (62.75%) males and 19 (37.25%) females, 21 (41.18%) with hypothalamic hamartomas (HH) and 30 (58.82%) with non-hypothalamic hamartomas. The age of onset was earlier in the HH group than in the non-HH group, with a median age of onset of 24.00 (0.00 ~ 96.00) and 78.00 (1.00 ~ 396.00) months (P<0.001). There are three types of laughter according to their characteristics: smiling or pleasant expressions, laughing out loud, crying or bitter laughter, with smiling or pleasant expressions being the most common (49.02%). Simple laughter is rare in all patients and is often accompanied by other manifestations such as autonomic symptoms, automatic movements, complex movements, and tonic seizures. Most of the HH group started with laughter whereas in the non-HH group laughter appeared mostly in the mid to late stages (P=0.007). Most of the HH group (57.14%) had preserved consciousness whereas most of the non-HH group (83.33%) had loss of consciousness (P=0.003). The interictal discharges in the HH group were mostly diffuse or multiregional, whereas those in the non-HH group were mostly regional (P=0.035). The onset of EEG during the seizure period in the HH group was mostly diffuse, whereas those in the non-HH group were mostly regional, mainly in the frontal and temporal regions, but there was no significant difference between the two groups (P=0.148). The non-HH group was mostly seen in those with definite lesions, and the most common type of lesion was FCD (focal cortical dysplasia, FCD). All patients enrolled in the group underwent surgical treatment, and stereoelectroencephalogram (SEEG) electrode implantation was performed in 13 cases in the HH group and in 17 cases in the non-HH group. 61.90% of the patients in the HH group had an Engel grade I, and 73.33% of the patients in the non-HH group had an Engel grade I. ConclusionsGelastic seizures has a complex neural network, with common causes other than hypothalamic hamartomas, and is most commonly seen in frontal or temporal lobe epilepsy, as well as in the insula or parietal lobe, with the most common type of lesion being FCD. The symptomatology, stage of onset, and electroencephalographic features of gelastic seizures can help in the differential diagnosis, and SEEG can help define the origin of the seizure and its diffusion pathway. The overall prognosis of surgical treatment was better in both the hypothalamic hamartomas and non-hypothalamic hamartomas groups.
