ObjectiveTo investigate the clinical characteristics of non-tuberculous mycobacterium (NTM) pulmonary disease and pulmonary tuberculosis, as well as the bacterial distribution of NTM pulmonary disease. Methods The bacterial distribution and clinical characteristics of 104 patients with NTM lung disease hospitalized in Jiangxi Provincial People’s Hospital from May 2017 to May 2020 were retrospectively analyzed, as well as the clinicplal characteristics of 155 patients with tuberculosis hospitalized during the same period. Results The age of NTM lung disease group [(60±15) years] was higher than that of tuberculosis group [(55±19) years]. There were statistically significant differences in basic diseases (such as malignant tumor, type 2 diabetes, old tuberculosis, bronchiectasis), laboratory examination (such as blood routine examination, albumin) and chest imaging characteristics between the two groups (P<0.05). There was no significant difference in clinical symptoms (such as cough, sputum or fever) (P>0.05). The common underlying diseases of NTM lung disease were malignant tumor (29%), bronchiectasis (21%), chronic obstructive pulmonary disease (19%), etc. The common clinical symptoms of NTM lung disease included cough, sputum, fever, hemoptysis, chest tightness and shortness of breath, and other non-specific respiratory symptoms. The common manifestations of NTM lung disease on chest high-resolution CT (HRCT) included patchy images (82%), mediastinal lymph node enalargement (35%), pleural thickening (31%), pleural effusion (26%) and other signs. The isolates of NTM included Mycobacterium avium (50%), Mycobacterium intracellulare (21%), Mycobacterium chelonae/abscessus (14%), Mycobacterium fortuitum (5%), Mycobacterium gordonae (4%), Mycobacterium gilvum (3%), and Mycobacterium smegmatis (3%). Multivariate Logistic regression analysis showed that advanced age (OR=1.027) was a risk factor for NTM lung disease. Conclusions The clinical manifestations of NTM lung disease and tuberculosis are similar and difficult to distinguish. For male patients over 60 years old with malignant tumor, old tuberculosis, bronchiectasis and other basic diseases, and the chest HRCT findings are mainly bronchiectasis, NTM lung disease should be actively excluded. There is little difference in clinical manifestations between different strains of NTM lung disease, and the treatment cycle of NTM lung disease is long and easy to be interrupted, requiring enhanced follow-up.
Objective To summarize the clinical features, diagnosis and treatment of postinfection bronchiolitis obliterans. Methods Clinical manifestation, chest X-ray, characteristics of lung function,computed tomography ( CT) of 6 patients with postinfection bronchiolitis obliterans from August 2009 to June2012 were analyzed retrospectively.Results All 6 cases were diagnosed as bronchiolitis obliterans after pneumonia. One patient had severe pneumonia complicated with congenital atrial septal defect and heart failure. 3 cases were complicated with varying degrees of cardiac insufficiency. Adenovirus in sputumsample were found in2 cases, smear positive for parainfluenza virus was found in1 case, mycoplasma were found in 2 cases, and no specific pathogen was found in the last one. All 6 cases were suffered frompersistent cough,wheezing and shortness of breath with three depression sign in 4 cases. The symptoms lasted for at least 6 weeks. Crackles and wheezing were present in all 6 cases. Small airway lesion was presented by pulmonary CT. Bronchiectasis was showed in 2 cases, atelectasis in 1 case, and consolidation in 1 case. Pulmonary function tests showed mixed ventilatory dysfunction. Bronchofiberscope examination was operated in5 cases,only endotracheitis was found. Prednisone and azithromycin were given orally in all the cases, but the clinical symptoms were persistent in the course of treatment and no death occured. Conclusions Clinical symptoms of bronchiolitis obliterans are characterized by persistent cough and wheezing. Small airway lesions were present in pulmonary CT. Repeated lower respiratory infection is common. Prednisone is widely used in treatment of bronchiolitis obliterans, but the therapeutic effect is uncertain.
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.
ObjectiveTo observe the clinical and fundus imaging features of acute macular neuroretinopathy (AMN) associated with COVID-19. MethodsA retrospective case study. A total of 32 eyes of 18 patients diagnosed of AMN associated with COVID-19 at Chengdu Aidi Eye Hospital from December 2022 to February 2023 were included. All patients had a history of fever 1 to 5 days prior to ocular onset and tested positive for SARS CoV-2 antigen. All patients were examined by best-corrected visual acuity (BCVA), color fundus photography, scanning laser ophthalmoscope (SLO), infrared fundus photography (IR), and optical coherence tomography (OCT); OCT angiography, visual field and multifocal electroretinogram (mf-ERG) were performed in 6 patients (11 eyes), 3 patients (6 eyes) and 1 patient (2 eyes), respectively. Follow-up time was 8-10 weeks. The clinical and fundus imaging features were observed and analyzed.ResultsThere were 6 males (12 eyes) and 12 females (20 eyes), aged from 15 to 36 years, with the mean age of (28.00±5.86) years. Fourteen patients were bilateral and 4 patients were unilateral. The time from the onset of eye symptoms to seeing a doctor was ranged from 1 day to 8 weeks. Among them, 6 patients (10 eyes) visited the doctor within 3 days of onset, while 12 patients (22 eyes) visited the doctor after 3 days of onset. The BCVA was 0.80±0.29. Fundus color photography and SLO examination showed that only 2 patients (4 eyes) showed sheet or petal-like dark red lesions in the macular area, and no obvious abnormal changes were observed in other patients. No obvious abnormalities were found in AF examination of all patients. IR examination showed no significant abnormality in 6 cases which came to hospital within 3 days after the onset, but irregular hyporeflective dark shadow lesions in the macular region of patients with more than 3-day course of disease was observed. OCT examinations of all eyes showed hyperreflective band or patchy lesion on the outer plexiform layer (OPL) and outer nuclear layer (ONL) and affect the ellipsoid zone (EZ) and interdigitation zone (IZ). In 11 eyes of 6 patients undergoing OCTA examination, the blood flow density of the choroidal capillary layer in the focal area decreased. In 6 eyes of 3 patients who underwent visual field examination, the physiologic scotoma was slightly enlarged. One patient (2 eyes) receiving mf-ERG showed a concave reduction in macular center amplitude. The hyperreflective band lesion on OPL and ONL disappear rapidly within 2 weeks, while the continuity of EZ recovered slowly, and the disruption of IZ kept existing for more than 10 weeks. ConclusionsMost AMN associated with COVID-19 are young women; IR showed irregular weak reflex in the lesion area. OCT showed strong OPL and ONL reflection. OCTA was characterized by decreased blood flow density in the choroidal capillary layer of the focal area.
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.
Glioma related epilepsy (GRE) is a complication that seriously affects the quality of life and treatment process of glioma patients. The genes and biomolecules in the tumor microenvironment may contribute to the mechanisms and pathways of epilepsy. In addition, it has been found that epileptic seizures can promote the growth of brain tumors, making controlling epilepsy a key factor in treating brain tumors., However, in current understanding, not all genetic molecular features carried by gliomas themselves are involved in the pathogenesis of GRE. With the deepening understanding of GRE, it has been discovered that some molecular features of gliomas are involved in the pathogenesis of GRE, mainly through the Ras/Raf/MAPK (MEK)/ERK and PI3K/AKT/mTOR pathways, which are also involved in the pathogenesis of gliomas. In 2021, the World Health Organization (WHO) classified diffuse gliomas into two categories: adult and pediatric, and further subdivided them into types such as astrocytoma, oligodendroglioma, and glioblastoma. This classification helps to more accurately understand and apply the molecular characteristics of gliomas, promote the standardization of tumor pathological diagnosis, and may have an impact on the treatment and prognosis evaluation of GRE. This review links genes and biomolecules in the tumor microenvironment through the latest WHO classification, summarizes previous research and recent findings, and provides a deeper understanding of the molecular characteristics of gliomas and their relationship with epilepsy related molecular pathways. It explores more effective treatment methods to suppress epilepsy symptoms and tumor growth, which is of great significance for improving the diagnosis and treatment of GRE.
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 investigate clinical features and progress in women with catamenial epilepsy. MethodsThe data obtained from retrospective study in 20 patients with catamenial epilepsy and reviewing published study of catamenial epilepsy. ResultsSeizures of all cases were relatived with the menstrual cycle. Seizures that only occured perimenstrually in 7 cases, 13 cases experienced exacerbation during this time. Only 2 of the 20 cases pointed to generalized sizures.12 of 18 cases which were partial seizures identified with complex partial seizures. Of 17 patients who had EEG results, 1 showed mild abnormal waves, 1 showed slow waves, 1 showed sharp waves, 1 showed spike and slow wave complex, 2 showed generalized polyspike and slow wave complex, 11 showed focal sharp waves,spike waves and spike and slow wave complex. All patients accepted 1 or more AEDs treatment.1 patient seizure free for 2 years after menopause, 2 cases of treatment were unclear, 5 cases had positive outcomes(4 cases seizure free for 1 and more years,1 case for 6 months), 12 cases were poorly controlled, especially 9 cases were refractory epilepsy. ConclusionIt is found that catamenial epilepsy more commonly in facal and the rate of refractory epilepsy is higher. Treatment of catamenial epilepsy power with more samples, multi-center clinical trials.
Objective To propose the terminology of acoustic hypersensitivity, and investigate its clinical features and relationship with tinnitus. Methods A total of 214 patients with acoustic hypersensitivity or tinnitus as their first chief complaint were recruited and studied between January 2014 to January 2016. Detailed information of clinical manifestations, accompanying symptoms and related medical history were collected in the patients with acoustic hypersensitivity. Patients were instructed to complete the Hyperacusis Questionnaire and the Self-rating Anxiety Scale. The Tinnitus Evaluation Questionnaire was used to evaluate tinnitus severity in patients with tinnitus. Results Among the patients with acoustic hypersensitivity as their first chief complaint, 93.3% had tinnitus; 47.3% of the patients with tinnitus as their first chief complaint had acoustic hypersensitivity and the prevalence of acoustic hypersensitivity increased as the tinnitus severity increased. In terms of onset of the two symptoms, simultaneous acoustic hypersensitivity and tinnitus occurred in 55.1% of the patients, acoustic hypersensitivity occurred after tinnitus in 34.7% of the patients, and acoustic hypersensitivity occurred before tinnitus in 10.2% of the patients. Most patients with acoustic hypersensitivity as the first chief complaint felt uncomfortable to any sounds that are louder than usual. The main manifestations included feeling disturbed, echoing in the ear or head, ear fullness or pain. Discomfort in 68.6% of the patients disappeared when there was no environmental sound. It was found that hearing loss, ear fullness, vertigo, and anxiety were usually present in patients with acoustic hypersensitivity, and 28.6% of the patients with acoustic hypersensitivity had a history of noise exposure. Conclusions Acoustic hypersensitivity occurs together with tinnitus for the majority of time, which shows a close relationship between these two symptoms. However, acoustic hypersensitivity shows different clinical manifestations from tinnitus. It is important to unify the terminology and standardize the concept of acoustic hypersensitivity among clinicians. It is also critical to conduct more clinical research in terms of diagnosing and evaluating acoustic hypersensitivity.
