ObjectiveTo analyze the epidemiological and clinical characteristics of severe cases of coronavirus disease 2019 (COVID-19) in order to provide reference for clinical diagnosis and treatment.MethodThe epidemiological histories, clinical characteristics, laboratory examinations, chest images, and treatment outcomes of 20 confirmed cases of severe COVID-19 admitted to Public Health Clinical Center of Chengdu from January 16th to February 5th, 2020 were retrospectively analyzed.ResultsAmong the 20 patients with severe COVID-19, 12 were male and 8 were female. The age ranged from 34 to 84 years old, with an average of (57.4±16.5) years old. Thirteen patients (65.0%) had one or more co-existing diseases, such as hypertension (9 cases), diabetes (6 cases), and coronary atherosclerotic heart disease (4 cases). Eleven cases (55.0%) had a history of living or traveling in Wuhan, 4 cases (20.0%) had a history of living in non-Wuhan areas of Hubei Province, 3 cases (15.0%) had a history of contact with confirmed COVID-19 patients, while 2 cases had no above-mentioned epidemiological history, but had a history of traveling in non-epidemic areas. The main symptoms were fever (100.0%), cough (100.0%), shortness of breath (75.0%), and fatigue (65.0). Some patients developed into acute respiratory distress syndrome in 3-10 d after onset. The white blood cell count of the patients was normal or decreased, the hypersensitive C-reactive protein and serum amyloid protein significantly increased, while the CD4+ T lymphocyte count and CD56+ natural killer cell count significantly decreased. Sixteen patients (80.0%) were given transnasal hyperbaric oxygenation [among whom 6 patients (30.0%) were transferred to non-invasive ventilator after no improvement], 3 patients (15.0%) were given tracheal intubated ventilator, and 1 patient (5.0%) was treated by tracheal intubated ventilator combined with extracorporeal membrane oxygenation to support breathing. By April 8th, 2020, 3 patients died and the remaining 17 had been cured and discharged, with an average length of hospital stay of 21.4 d. The 3 death cases were all elderly with underlying diseases such as heart disease and pulmonary disease.ConclusionsSevere COVID-19 is associated with hypertension, diabetes, heart disease, and other basic diseases, and some patients develope acute respiratory distress syndrome. Respiratory support may help to improve prognosis.
Objective To analyze the spinal injury in Wenchuan earthquake and to investigate its cl inical features. Methods Data of 146 patients in Wenchuan earthquake with spinal injuries (79 males, 67 females; aged 11-88 years old, average 51 years old) were collected and analyzed epidemiologically. Two patients under 16 years of age, 15 patients withthe fractures of spinous process, transverse process or vertebra lamina, 1 patient with spinal fractures of type A2 according to AO classification but no corresponding type in Denis classification, and 9 patients with upper cervical injuries were excluded. The remaining 119 patients were divided into two groups according to their age: group A in which 78 patients were under 60 years of age, including 40 males and 38 females aged 18-58 years old (average 41 years old), and group B in which 41 patients were 60 years of age or above, including 24 males and 17 females aged 60-88 years old (average 71 years old). Analyses for the two groups were compared. Results The leading causes of spinal injuries were fall from high places (27.40%) and crush by heavy objects (67.81%). According to Denis classification, the major types of spinal injuries were burst fracture (54.62%) and compression fracture (33.61%). Serious nerve injury, defined as grade A, B and C in ASIA neurological function assessment, occurred in 31.51% of patients. The most common injured site was in thoracic or lumbar vertebrae (78.77%), and 52.74% of patients had combined injuries, among which the fractures of l imb (30.14%) and rib (19.86%) were the most common. Multilevel spinal fractures happened to 22.60% of patients. Comparative analysis revealed the rate of injury caused by fall from high places in group A (34.62%) was much higher than that in group B (12.20%). The commonest type of fracture in group A was burst fracture (58.97%), and it was compression fracture in group B (48.78%). The rate of serious nerve injury in group B (24.39%) was much lower than that in group A (44.87%). The rate of combined injury and multilevel vertebral body injury in group B was 70.73% and 39.02%, respectively, which was much higher than that in group A (combined injury 43.59%; multilevel vertebral body injury 21.79%). There were significant differences between two groups in all the indicators derived from cl inical data (P lt; 0.05). Conclusion In Wenchuan earthquake, the leading causes of spinal injuries are fall from high places and crush by heavy objects, the major types of fracture are compression fracture and burst fracture, and the occurrence rates of spinal injury, combined injury and multilevel vertebral body injury are high.
ObjectiveTo analyze the clinical features of psychogenic non-epileptic seizures (Psychogenic nonepileptic seizures, PNES) in Tibetan population in Tibet, so as to help clinicians identify the disease.MethodsRetrospective analyzed the clinical data of patients with PNES in the Department of Neurology, People's Hospital of Tibet Autonomous Region from June 2016 to December 2018.ResultsIn general clinical data, there were significant differences between male and female patients in the results of video electroencephalogram (EEG) monitoring the non-epileptic seizures (P< 0.05). There were no significant differences in mean age, mean onset time, family history of epilepsy, head injury and marital status between male and female patients (P> 0.05). There was no significant difference in symptoms between male and female, but there were differences among different age groups (P> 0.05). In the onset age, the main manifestation was young women, but there was no significant difference in the onset of PNES among different age groups.ConclusionsThere was significant differences between male and female PNES petients, but no significant differences in onset time, marriage and family history of epilepsy between the male and female patients with PNES in Tibet. The clinical manifestations of PNES were different in different ages of patients in Tibet.
Objective To investigate the clinical features, diagnosis, and treatment of patients with localized epithelioid sarcoma (ES).Methods From January 2000 to September 2006, 11 patients with ES weretreated. There were 7 males and 4 females aged 14-41 years. The patients’ agesat the initial onset were 9-41 years, averaged 27.7 years. The ES was located in the upper extremity in 7 patients，lower extremity in 3, and abdomen in 1. Among the patients, 10 had a recurrence. Tumor lt; 2cm was seen in 7 patients, 2-5cm in 1, and gt;5 cm in 3. One patient underwent an operation of local resection at another hospital. Seven patients underwent an expanding resection surgery, and the tumors with the surrounding normal tissues 3 cm above were removed. Three patients underwent a radical surgery, including extremity amputation or finger amputation. All the patients underwent routine radiotherapy and chemotherapy after operation. Results All the wounds had a healing at the firstintention without complications. All the flaps survived and the grafted bone had a fusion. Among the 11 patients followed up for 5-54 months averaged 23.2 months, 8 had a recurrence 2-20 months (average, 8.9 months) after operation, witha recurrence rate of 73%. And among the patients, 3 had a further radical surgery of extremity amputation. Four patients had a metastasis in the axillary lymphnodes 6-24 months after operation, and 1 patient had a lung metastasis 10 months after operation. They did not have a further surgical treatment. Four patients died of systemic failure 6-14 months after operation. Conclusion An early expanding resection surgery combined with postoperative chemotherapy and radiotherapy is the therapy of choice for treating ES.
ObjectiveTo investigate the clinical features and changes of EEG in children with late onset epilepsy spasm. MethodsThe clinical data, treatment, follow-up and outcome of 13 patients with late-onset epilepsy spasms were analyzed retrospectively from June 2010 to August 2015 in Bo ai Hospital of Zhong Shan City.Affiliated Southern Medical University ResultsThirteen cases of children were enrolled in the group, including 9 males and 4 females, the onset of age were 1 year 3 months to 5 years 7 months, duration of treatment were 1 year 5 months to 4 years 8months.Seven cases of children had clear cause in 13 patients: 2 cases of viral encephalitis, 3 cases of HIE, 1 case of neonatal sepsis, ARDS, and 1 case of methylmalonic acid hyperchomocysteinemia.Six cases did not clear the cause.Spasm is still the main type of Seizures.Seven cases had seizures with partial origin.the most onset time were awake period and wake up for the time, and coexisted with other types of seizures.EEG in Epileptic seizures period was a broad range of high amplitude slow wave, slow bursts, complex or non-composite low amplitude fast wave, sometimes with the burst after the voltage attenuation of a few seconds, string or isolation occurs.Synchronous bilateral deltoid EMG monitoring showed bilateral or unilateral synchronous EMG 1 ~ 2s Bilateral or unilateral synchronous EMG outbreak1-2s.Intermittent EEG showed multifocal and extensive epileptic discharge, still sharp (spine) slow wave continuous release based.Treatment: All children underwent ACTH or methylprednisolone immunoregulation treatment, 3 cases underwent ketone diet therapy.At the same time choice valproic acid, topiramate, clonazepam, lamotrigine, levarabesilan and other anti-broad-spectrum antiepileptic drugs, according to the history.all children were taken in combination with the way.Prognosis: 13 patients'seizures reduced or controled after the end of the ACTH or methylprednisolone immunotherapy course.followed-up 3 to 12 months, the clinical attack control were failed 3 cases had relatively good prognosis, treated with Ketogenic diet (Lasted for 1 year 3 mothes~2 years 5 mothes), one case of attack control, mental improvement significantly, Another 2 cases, the numbers of episodes were reduced and the level of intelligence were significantly improved. ConclusionPerinatal factors and acquired brain injury are the most common cause of pathogenesis.Spasm as a major form of attack, and other forms of coexistence.EEG is not typical of high degree of performance.Simultaneous EMG monitoring shows bilateral or unilateral synchronous EMG outbreaks.The treatment of various antiepileptic drugs were ineffective.The vast majority of patients developed refractory epilepsy.Ketogenic diet treatment may be a relatively good choice.

ObjectiveTo analyze the clinical characteristics of thrombo embolism (TE) in Chinese hypertrophic cardiomyopathy (HCM) patients. MethodsThis study retrospectively analyzed HCM patients admitted to West China Hospital of Sichuan University. The endpoints were defined as a composite of TE events, including ischemic stroke, transient ischemic attack, and peripheral arterial embolization. ResultsA total of 537 HCM patients were included with a median follow-up of 4.2 years. Forty-two patients reached the TE endpoint and the incidence was 1.9%. The annual incidence of TE was approximately 1.1% and 6.6% for HCM patients without/with atrial fibrillation, respectively. The recurrence rate of TE was high (approximately 26.2%). The mean age was 66.4±13.7 years for the first TE, and the incidence of TE was significantly increased at age ≥70 years. ConclusionThe incidence of TE is high in HCM patients, especially in those with atrial fibrillation, and the recurrence rate of TE is also high.
ObjectiveTo explore the clinical features and prognosis of ischemic cerebral infarction in young population,and to provide a reference for clinical prevention of cerebral infarction in young population. MethodsA total of 547 patients with ischemic cerebral infarction diagnosed between January 2008 and June 2013 were included,and the difference in clinical data and outcomes between young and old patients were retrospectively compared. ResultsThe 547 patients included 233 young and 314 old patients,and there were more male patients in young group.As compared to the old group,the proportion of hypertension was significantly lower in young group (51.9%,64.3%;P=0.004);while smoking (51.9%,5.7%;P=0.000) and alcoholism (53.2%,28.3%;P=0.000) were significantly higher in young group.Moreover,there were more patients with vascular malformations in young group than that in old group (7.3%,3.2%;P=0.028).And there were also more patients in young group received thrombolytic therapy and antiplatelet therapy (98.3%,86.9;P=0.000),and the prognosis of young patients was significantly better than that of old patients. ConclusionThe prognosis of young patients with ischemic stroke prognosis is relatively good,and changing bad habits would be an effective measure to prevent and reduce the occurrence of ischemic cerebral infarction in young population.
Objective To improve the knowledge of pulmonary mucormycosis through summarizing the clinical features and treatment of the disease. Methods A retrospective analysis was conducted on two cases of mucormycosis. The literature review was carried out with " pulmonary mucormycosis” as the research terms respectively in CNKI and Pubmed database. Search time ranged from January 2000 to June 2016. Results The first case was a 61-year-old male patient complained of cough, expectoration and dyspnea for 5 days. Chest computerized tomography (CT) showed lung nodules in the right upper lobe and bronchial cut off sign of apical bronchus. The patient received bronchoscopic examination and pathological findings indicated mucormycosis. Amphotericin B was recommended for the treatment. The patient recovered after treatment and was discharged. The second case was a 44-year-old female patient admitted to our hospital due to cough accompanied with expectoration and fever for over 10 days. Chest CT scan showed multiple double-pulmonary circular nodules and cavities with different sizes and clear boundary. The maximum cavity diameter was about 1.8cm, and the density of soft tissue was found in the part of the cavity. The patient received CT-guided percutaneous lung biopsy and pathological findings indicated fungal hyphae which was accorded with mucor infection. The patient received amphotericin B, voriconazole and posaconazole treatment, but with bad curative effect. She gave up therapy and died one week later after discharged. A total of 6 literatures were reviewed in above-mentioned databases. The clinical manifestations were nonspecific and the patients were likely to accompany with other diseases. The duration from the onset of symptoms to exact diagnosis was 37.5 days. Chest CT scan and pathological examination played important roles in the diagnosis of mucormycosis. Proper antifungal treatment could improve the prognosis. Conclusions Mucormycosis is a rare invasive fungal disease with high mortality. The clinical manifestations are nonspecific. Early diagnosis and appropriate treatment contribute to better prognosis.
ObjectiveTo explore the clinical and video EEG features of patients with post-stroke epilepsy (PSE).MethodsThe clinical data of 68 patients with epilepsy after cerebral infarction and 33 patients with epilepsy after cerebral hemorrhage were analyzed retrospectively from January 2015 to June 2018 in the Affilated Hospital of Jining Medical University. There were 5 cases of early-onset epilepsy, and the rest were late-onset epilepsy. There were 68 cases of cerebral infarction (1 case showed post-infarction hemorrhagic transformation), 33 cases of cerebral hemorrhage; 51 females, 50 males (f∶m = 1.02∶1); the onset age was 45 ~ 101 years, with an average of (68.10 ± 10.26) years.ResultsThe time from seizure to stroke in 101 cases was (28.92 ± 35.61) months, 60 cases (59.40%) ≤ 1 year, 26 cases (25.74%) 1 ~ 5 years, and 15 cases (14.85%) 5 ~ 10 years. Post-stroke epilepsy had no relation to gender (P>0.05). The age of onset is mostly in 60 to 75 years old (62.38%). Seizure often happen within 1 year after stroke (59.4%). The type of attack is focal seizure (77.23%). Cortical infarction (77.94%), cerebral artery stenosis (83.82%), hypertension, diabetes, and atrial fibrillation are risk factors for epilepsy after infarction. The abnormal rate of EEG for PSE is 90.1%, which was manifested as slow wave in the lesion side, epileptic wave in the lesion side or contralateral side.ConclusionsThe location, duration, age and severity of cerebral artery stenosis in patients with PSE are closely related to the occurrence of seizure. VEEG plays an important role in the diagnosis, treatment and prognosis of epilepsy.
