ObjectiveTo analyze the clinical characteristics and epidemiological characteristics of patients with coronavirus disease 2019 treated early in Jiangxi province.MethodsFour-night patients with coronavirus disease 2019 treated in this hospital from January 21st to 27th, 2020 were included in this study. The epidemiological and clinical data of patients after admission were collected, and laboratory tests such as blood routine, urine routine, stool routine, liver and kidney function, electrolytes, myocardial enzymes, erythrocyte sedimentation (ESR), C-reactive protein (CRP), calcitonin, coagulation, T cell subset and Chest CT were reviewed. The clinical results of common and severe/critically ill patients were compared.ResultsOf the 49 patients, 40 were common and 9 were severe/critical. Fourty-six patients had a clear history of contact with Wuhan or other areas of Hubei. The sex ratio was 2.06∶1, and the average age was 42.9 years. The symptoms were mainly fever (78.7%), cough (38.8%), and fatigue (18.4%). 28.6% (14 cases) of patients had hypertension and diabetes. Serum lymphocyte count and calcium concentration of the patients were decreased, but lactate dehydrogenase, ESR, CRP and serum amyloid A were increased in these patients. T lymphocyte subsets (CD3+, CD4+, CD8+) decreased significantly in these patients. Forty-seven patients (95.9%) had single or scattered patchy ground glass density shadows on the chest CT. Compared with common patients, the patients with severe/critical patients were older (P=0.023), hospitalized later (P=0.002), and had higher comorbidities (P=0.017). ESR (P=0.001）, CRP (P=0.010) and the serum amyloid A (P=0.040) increased significantly, while CD3+ (P<0.001), CD4+ (P=0.012), CD8+ (P=0.006) decreased significantly in severe/critical patients.ConclusionsThe patients with coronavirus disease 2019 in Jiangxi province are commonly imported from Wuhan. Severe/critical patients are older, hospitalized later, and have more medical complications and more severe systemic inflammatory reactions than common patients.
Objective To investigate early clinical manifestations of osteogenic sarcoma to help establishment of an early diagnosis of the disease.Methods A total of 92 patients with osteogenic sarcoma in the extremities were admitted to our hospital from April 1984 to October 2002. Of the 92 patients, 71 (42 males and 29 females; averaged age 17.4 years, range 666 years; illness course 1-28 weeks) had a complete record of their medical history and examination. From their first medical visits, we obtained their clinical symptoms, physical sings, diagnoses, and duration of the delayed diagnoses. The patients were pathologically confirmed as having osteogenic sarcoma in the extremities, with the lesions located in the distal femur in 38 patients, proximal tibia in 22, proximal femur in 3, proximal fibula in 3, proximal humerus in 2, distal tibia in 2, and distalradius in 1. Results Of the 71 patients, 70 had a local pain and/or a palpable mass, 37 had a persistent pain with no difference between day and night, 23 had an intermittent pain, and 11 had a nocturnal pain. Of the 71 patients, 42 had an initial pain related to trauma, and 3 of the 42 patients had a pathologic fracture. The patients with the local mass had a delayed diagnosis of osteogenic sarcoma with a delayed duration of 1-14 weeks, averaged 4 weeks; however, the patients without the local mass had a delayed diagnosis of this disease, with a delayed duration of 3-30 weeks averaged 14 weeks. In the patients undergoing an X-ray examination at the first medical visit, the duration of the delayed diagnoses was 1-20 weeks, averaged 8 weeks, but in the patients without an X-ray examination at first, the duration was 4-30 weeks, averaged 16 weeks. Conclusion Intermittent and persistent pains and local masses are the most characteristic clinical manifestations in the early stage of osteogenic sarcoma. A history of trauma often helps to make a diagnosis of the disease. Carefulclinical examination and observation should be given to adolescent patients whohave a recurrent pain around the joint.
ObjectiveTo investigate the clinical and imaging features of patients with pulmonary lymphangioleiomyomatosis (PLAM),to improve the knowledge of this disease. MethodsEighteen patients with PLAM admitted into Zhongshan Hospital between 2003 and 2013 were retrospectively analyzed. Relevant literatures were reviewed. ResultsAll the 18 cases were female and had dyspnea on exertion. Three of them suffered from chylothorax,6 from pneumothorax and 5 from hemoptysis. The high resolution CT (HRCT) findings in all the 18 cases showed multiple small cysts with thin wall diffusely distributing in the bilateral lung. PLAM was confirmed by biopsy in 14 cases. Pulmonary function tests in 4 cases showed obstructive ventilatory dysfunction. Nine cases (50%) were misdiagnosed as other diseases. All the patients were given symptomatic and supportive treatment. Literatures review showed that as a rare diffuse lung disease,PLAM is more common in women of childbearing age,mainly presenting with dyspnea,hemoptysis,pneumothorax and chylothorax. Diagnosis of the disease relies on medical history,HRCT features and lung tissue biopsy pathology. HRCT examination has diagnostic value for PLAM. Although anti-estrogen treatment has certain effects,rapamycin may be a promising drug for PLAM therapy. ConclusionPatients with PLAM have characteristic clinical and radiographic manifestations. Early diagnosis and effective treatment are keys to the management of patients with PLAM.
ObjectiveTo observe and investigate the related factors that might affect clinical features of familial exudative vitreoretinopaty (FEVR) patients. MethodsA retrospective chart study. From January 2012 and December 2021, 42 patients with 84 eyes with a diagnosis of FEVR from Department of Ophthalmology, Peking University People's Hospital were included in the study. The patients came from 42 separate families. There were 31 males and 11 females, with an average age of first diagnosis was 16.6±33.7 months. There were 21 patients referred from other hospitals for the fundus disease found in eye screening after birth, 21 patients were first seen in our hospital. There were 4 and 38 premature and full-term infants, respectively. Two patients with a positive family history of FEVR. All patients are FEVR stages 1-5. The wide-angle digital pediatric retinal imaging system after general anesthesia for fluorescein fundus angiography (FFA) examination were performed for patients aged ＜5 years. If patients ≥ 5 years old, routine FFA examination was performed. Sixty-eight first-degree relatives from 28 families undergo routine fundus examinations and FFA examination. Genetic examination was performed for 26 families, including 26 probands and 57 first-degree relatives. Genetic examination were performed on gene the coreceptor of low density lipoprotein receptor-associated protein 5 (LRP5), Wnt receptor coiled protein 4 (FZD4), Norrie disease (NDP), tetraporin 12 (TSPAN12), catenin β1 (CTNNB1) genes known to be involved in FEVR. The clinical features and the genotype of FEVR were observed in relation to the clinical phenotype. ResultsAmong the 42 patients, 13 patients were first observed by strabismus and nystagmus, with the median age of 12 months. Eight patients were complained non-chasing or vision-related symptoms. Among the 84 eyes, FEVR stage 1 or 2, 3 or 4, and 5 were 50 (59.5%, 50/84), 31 (36.9%, 31/84), and 3 (3.6%, 3/84) eyes, respectively. Among the 23 patients who were > 3 months at first diagnosis, 16 patients had at least one eye severer than stage 3 (69.6%, 16/23). Of the 68 first-degree relatives, 22 (32.4%, 22/68) had FEVR-like changes. Among the 26 families that underwent genetic detection, 13 families (50%, 13/26) of 16 variants of FEVR-related genes were detected, of which 10 mutations of LRP5 gene were the most common. There were 10 families with single gene mutations, including 6, 2 and 2 families of LRP5, FZD4 and CTNNB1 genes, respectively. One family of LRP5 gene mutations were compound heterozygous mutations, 1 family with LRP5 gene mutaition combined with NDP gene mutation, and 1 family with LRP5 and TSPAN12 gene mutation. Among the proband with FEVR pathogenic genes, 6 cases with similiar stage of both eyes, and 7 cases with inconsistent disease stages, and there was no obvious correlation between gene mutations and clinical phenotypes. ConclusionIn addition to the age of first diagnosis, no exact factors affecting the clinical manifestations of FEVR are found, and the association between clinical phenotypic and genetic heterogeneity still needs to be further explored.
ObjectiveTo explore the clinical characteristics of different types of prolactinoma and the therapeutic effect of bromocriptine.MethodsThe medical records of patients with prolactinoma treated by bromocriptine from January 2010 to December 2016 were retrospectively analyzed, and the patients were followed up.ResultsA total of 106 cases of prolactinoma were included, in whom 67 were microprolactinomas, 31 were macroprolactinomas, and 8 were giant prolactinoma. There were differences in the distributions of gender and age, prolactin level, clinical manifestations and the effective dose of bromocriptine among the three groups (P<0.05). After the treatment of bromocriptine, the level of serum prolactin was restored to normal in 61 cases in microprolactinoma group, 26 cases in macroprolactinoma group and 6 cases in giant prolactioma group. For improvement of the main symptoms, there were 63 patients in microprolactinoma group, 27 in macroprolactinoma group and 6 in giant prolactioma group. Furthermore, the shrink or disappearance was achieved in 28 patients in microprolactinoma group, 23 in macroprolactinoma group, and 8 in giant prolactioma group. The statistical results showed no significant difference in normal prolactin level and improvement of symptoms among the three groups (P>0.05), but the reduction of tumor volume were statistically different (P<0.05).ConclusionsMicroprolactinomas and macroprolactinomas are mostly seen in childbearing-aged women with main manifestations of menstrual disorders and lactation, while giant prolactinomas are mostly seen in middle-aged men, with main manifestations of headaches and visual field disorders. Bromocriptine has a good effect on prolactin adenomas with various sizes. Therefore bromocriptine should be the first choice for different types of prolactinomas.
ObjectiveTo explore the effects of cytokines on Febrile seizures (FS) in children with febrile seizures (Febrile seizures), febrile seizures duration and prognosis, and to explore the correlation between cytokines and the clinical manifestations and prognosis of FS. MethodsA retrospective analysis was performed on 121 children with FS (77 cases in the simple FS group and 44 cases in the complex FS group) who were treated in the pediatrics department of the Maternal and Child Health Hospital of Inner Mongolia Autonomous Region from January 2021 to October 2022 as the experimental group, including 71 males and 50 females, with a male-to-female ratio of 1.42:1, according to the type of attack (93 cases in the comprehensive group, 44 cases in the complex FS group). The focal group (28 cases) and convulsion duration (91 cases in <5 min group and 30 cases in ≥5 min group) were divided into groups, and 127 cases of children with fever but no convulsions were compared with the control group. In addition, 121 children with FS were followed up for 1 year by neurology specialist outpatient department and telephone follow-up. According to the follow-up, they were divided into the first course group, the relapse group and the secondary epilepsy group, so as to further explore the correlation between cytokines and the prognosis of children with FS. ResultsExperimental group compared with control group: Serum IL-1β (1.38 pg/mL), IL-2 (2.26 pg/mL), IL-4 (1.53 pg/mL), IL-6 (10.51 pg/mL), IL-10 (3.09 pg/mL), IL-12p70 (1.74 pg/mL), TNF-α (2.11 pg/mL), IFN-γ (46.56 pg/mL), IL-1β (1.38 pg/mL), IL-1β (1.26 pg/mL), IL-4 (1.53 pg/mL), IL-6 (10.51 pg/mL), IL-10 (3.09 pg/mL), IL-12P70 (1.74 pg/mL), TNF-α (2.11 pg/mL), IFN-γ (46.56 pg/mL). IFN-α (25.92 pg/mL) levels were higher, and the differences were statistically significant (P<0.05). There was no significant difference between the simple group and the complex group (P>0.05). <5 min group compared with control group: serum levels of IL-2 (2.32 pg/mL), IL-4 (1.53 pg/mL), IL-6 (9.65 pg/mL), IL-12p70 (1.74 pg/mL), TNF-α (2.11 pg/mL), IFN-γ (44.63 pg/mL), IFN-α (29.67 pg/mL) were higher, and the differences were statistically significant (P<0.05). Compared with control group, the levels of IL-2 (2.06 pg/mL), IL-6 (14.67 pg/mL), IL-12p70 (1.97 pg/mL), IFN-γ (58.56 pg/mL) and IFN-α (17.50 pg/mL) in ≥5 min group were higher, and the differences were statistically significant (P<0.05). ROC curve analysis showed that serum IFN-α had a high predictive value for FS onset, the cut-off point was 8.64pg/ml, and the sensitivity and specificity were 75.63% and 76.38%, respectively. There was no significant difference between the first course of disease group, relapse group and secondary epilepsy group. ConclusionSerum proinflammatory cytokines IL-1β, IL-2, IL-6, IL-12p70, TNF-α, IFN-γ, IFN-α and anti-inflammatory cytokines IL-4 and IL-10 are involved in the pathogenesis of FS. There was no correlation between the simplicity and complexity of serum cytokines. IL-2, IL-6, IL-12p70, IFN-γ, IFN-α were positively correlated with the duration of convulsion. When serum IFN-α>8.64 pg/ml, the possibility of FS attack increased.
Hydroxychloroquine is widely used in a variety of autoimmune diseases. However, long-term use of hydroxychloroquine can cause severe retinopathy, which has a complex pathogenic mechanism and diverse clinical manifestations, mainly manifested as photoreceptor and retinal pigment epithelial damage and irreversible vision loss. Identifying damage before retinitis pigment epithelium lesions preserve central vision, so early detection is crucial to slow disease progression and reduce vision loss. The development of multimodal imaging technology and the issuance of the latest treatment guidelines provide a powerful tool for the early screening and treatment of hydroxychloroquine retinopathy. Proficient in the latest guidelines for the treatment of hydroxychloroquine can better guide clinicians to do a good job in disease screening and management, recommend risks, safe dosages and appropriate screening procedures to patients and strengthen the prevention of hydroxychloroquine retinopathy, which will help save the vision of more patients and reduce the waste of medical resources.
Pleuropulmonary blastoma (PPB) is a kind of rare malignancy which often occurs in children and is related to dysplasia. It always involves in pleura and lung. PPB is misdiagnosed easily because of its special pathophysiological characters and complex biological behavior. Early detection and correct treatment are very important for thoracic surgeon to cure PPB. This paper reviews the advance of pathophysiological characters, molecular genetic characters, clinical manifestation, clinical diagnosis and differential diagnosis, and treatment and prognosis of PPB.
Objective To improve the knowledge of pulmonary mucosa-associated lymphoid tissue (MALT)lymphoma. Methods A patient diagnosed as pulmonary MALT lymphoma was reported and related literatures were reviewed. Results The patient was a 58-year-old male,admitted due to intermittent fever,cough,sputum production,chest tightness and fatigue for 4 years.The patient was diagnosed as "pulmonary tuberculosis and tuberculous pleurisy" in other hospital and received anti-tuberculosis treatment for 3 years.The CT of the chest showed consolidation in the right middle lobe,right low lobe and left lower lobe with bronchial ventilation levy,miliary nodules in the right middle lobe,interstitial thickening,and right pleural effusion.Ultrasound guided lung biopsy pathology of the right lung showed diffuse small lymphocytes infiltration.The immunohistochemistry showed positive staining of CD20,CD79α and Vim,and weakly positive staining of Ki67(15%).Therefore,the patient was finally diagnosed pulmonary MALT lymphoma. Conclusions Pulmonary MALT lymphoma has no specific clinical manifestations,so is easy to be misdiagnosed as pulmonary tuberculosis,pneumonia or lung cancer.The patients with suspicious pulmonary MALT lymphoma should undergo percutaneous lung biopsy,transbronchial lung biopsy or open lung biopsy as soon as possible for immunohistochemistry staining to confirm the diagnosis.
ObjectiveTo summarize the clinical pathologic features of primary tonsil tumor, in order to provide reference for its diagnosis and treatment. MethodsWe retrospectively analyzed the clinical data from January 2002 to April 2012, and found 810 cases of malignant tumor and 113 cases of benign tumor. The pathologic patterns and clinical manifestations of these cases were recorded for analysis. ResultsMost tonsil tumors were unilateral, and the malignant types were much more than the benign. The most common malignant tonsil tumors were lymphoma (610 cases), followed by squamous cell carcinoma (172 cases); inverted papilloma was the most common benign tumor (87 cases). Paresthesia in the pharynx was the most common clinical manifestation that existed in almost all cases. ConclusionTonsil tumor pathological type is very important for its diagnosis, treatment and prognosis. Laying emphasis on pathological diagnosis and differential diagnosis could avoid missed diagnosis, misdiagnosis and improper treatment, which is particularly important for clinical physicians of the otolaryngology, head and neck surgery.
