INTRODUCTION: We aimed to compare the early clinical manifestations, laboratory results and chest computed tomography (CT) images of COVID-19 patients with those of other community-acquired pneumonia (CAP) patients to differentiate CAP from COVID-19 before reverse transcription-polymerase chain reaction results are obtained. METHODS: The clinical and laboratory data and chest CT images of 51 patients were assessed in a fever observation ward for evidence of COVID-19 between January and February 2020. RESULTS: 24 patients had laboratory-confirmed COVID-19, whereas 27 individuals had negative results. No statistical difference in clinical features was found between COVID-19 and CAP patients, except for diarrhoea. There was a significant difference in lymphocyte and eosinophil counts between COVID-19 and CAP patients. In total, 22 (91.67%) COVID-19 patients had bilateral involvement and multiple lesions according to their lung CT images; the left lower lobe (87.50%) and right lower lobe (95.83%) were affected most often, and all lesions were located in the peripheral zones of the lung. The most common CT feature of COVID-19 was ground-glass opacity, found in 95.83% of patients, compared to 66.67% of CAP patients. CONCLUSION Diarrhoea, lymphocyte counts, eosinophil counts and CT findings (e.g. ground-glass opacity) could help to distinguish COVID-19 from CAP at an early stage of infection, based on findings from our fever observation ward.

We reported a pediatric case of Kawasaki disease complicated with mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) from Beijing Tsinghua Changgung Hospital. The clinical data were retrospectively analyzed and the related literature was reviewed. The clinical features, treatment and prognosis of the disease were summarized to improve recognition of Kawasaki disease complicated with MERS. A 7-year-old boy was diagnosed with Kawasaki disease due to continuous high fever for 6 d, accompanied by strawberry tongue, conjunctival congestion, erythema-like hyperemia rash, and cervical enlarged lymph nodes. And treatment was started with intravenous immunoglobulin (IVIG: 2 g/kg) and oral aspirin [40 mg/(kg·d)]. Twenty-four hours after the treatment of IVIG, the patient' s fever persisted and in addition he developed headache and drowsiness. His cranial magnetic resonance imaging (MRI) demonstrated a localized lesion in the splenium of the corpus callosum with high intensity signal on diffusion-weighted images (DWI) and T2-weighted, and low intensity signal on apparent diffusion coefficient (ADC) and T1-weighted. Based on these findings, he was diagnosed with MERS-complicated Kawasaki disease. Methylprednisolone [2 mg/(kg·d)] treatment was started intravenously, and within several hours he was afebrile and the neurological symptoms disappeared. A follow-up MRI was conducted after 1 week was normal. He was discharged without any neurological sequelae and coronary artery lesions. A total of 12 qualified foreign literature were retrieved, with no Chinese literature searched. Seventeen children were reported, the median age was 6.5 years (range: 1-14 years), among them 11 cases were children over 5 years old, and 4 cases were complicated with coronary artery lesions. All children had neurological symptoms, such as consciousness disorder, visual hallucination or convulsion. MRI conformed to MERS imaging changes. After active treatment, the neurological manifestations and radiological abnormalities completely disappeared, leaving no neurological sequelae. Kawasaki disease complicated with MERS had not been reported in China by now. Literature that identified Kawasaki disease complicated with MERS mostly occurred in children over 5 years old. Cranial MRI examination is helpful for early diagnosis. Timely treatment can reverse MERS in a short time, without neurological sequelae left.

Hemophagocytic lymphohistiocytosis (HLH) was a life-threatening syndrome due to the uncontrolled immune activation of cytotoxic T lymphocytes, natural killer (NK) cells, and macrophages. HLH is characterized by primary and secondary causes, the early diagnosis and treatment of patients are closely related to the prognosis and clinical outcome of patients. The clinical presentation is variable but mostly includes prolonged fever, splenomegaly, coagulopathy, hypertriglyceridemia, and hemophagocytosis, none of them is specific and particular for HLH. Tuberculosis (TB) infection is one of the causes of HLH. HLH caused by TB is very rare clinically, but it has a high mortality. For patients with fever of unknown origin, HLH-related clinical manifestations sometimes present before the final diagnosis of TB, and HLH is associated with the most significant mortality rate. This article is mainly about a 28-year-old patient with HLH who suffered from severe TB infection. The patient attended a hospital with a history of 2 months of prolonged fever, 10 days booger and subcutaneous hemorrhage in lower limbs. Before this, he was in good health and denied any history of tuberculosis exposure. Combined with relevant laboratory test results (such as splenomegaly, hemoglobin, platelet count, and hypertriglyceridemia) and clinical manifestations (e.g. fever), the patient was diagnosed with hemophagocytic lymphohistiocytosis, but the etiology of HLH remained to be determined. To confirm the etiology, the patient was asked about the relevant medical history (intermittent low back pain) and was performed chest CT scan, bone marrow biopsy, and fundus photography. Finally, he was diagnosed with hemophagocytic lymphohistiocytosis caused by hematogenous disseminated pulmonary tuberculosis. In response to this, intravenous methylprednisolone and anti-tuberculosis treatment (isoniazid, pyrazinamide, moxifloxacin, and amikacin) were administered to the patient. After more than a month of treatment, the patient recovered from HLH caused by severe TB infection. Therefore, this case suggests that we should be vigilant to the patient who admitted to the hospital with fever for unknown reasons, to diagnose HLH as early as possible and clarify its cause, then perform interventions and treatment, especially HLH secondary to tuberculosis. Also, cases of atypical TB and severe TB should be carefully monitored to achieve early diagnosis and early intervention.

OBJECTIVE: To study the clinical features of children with recurrent Kawasaki disease (KD). METHODS: PubMed, Web of Science, Embase, CNKI, Wanfang Med Online, and Weipu Data were searched for case-control studies on the clinical features of initial and recurrent KD. The articles were screened according to the inclusion and exclusion criteria. RevMan 5.3 software was used to perform the Meta analysis. Effect models were selected based on the results of heterogeneity test, and then pooled RESULTS: A total of 9 case-control studies were included, with 12 059 children with KD in total, among whom 206 children had recurrent KD (127 boys/61.7%; 79 girls/38.3%). The results of the Meta analysis showed that compared with the initial KD onset, the children with recurrent KD had a shorter duration of fever ( CONCLUSIONS Current evidence shows that children with recurrent KD tend to have a shorter duration of fever and a lower incidence of swelling of the hands and feet. KD recurrence is more common in boys. Current evidence does not show an increased risk of developing coronary artery lesions in children with recurrent KD.

Objective To explore the clinical and laboratory characteristics and the prognosis of disseminated non-tuberculous mycobacteria(NTM)diseases in human immunodeficiency virus(HIV)negative patients. Methods Cases of disseminated NTM disease were retrospectively collected in Peking Union Medical College Hospital from January 2012 to October 2018.Clinical manifestations,laboratory findings,treatment,and prognosis of these cases were retrieved from the electronic medical record system. Results Among the 23 HIV negative patients with disseminated NTM disease,21 had underlying diseases,with rheumatoid immune disease(n=7)as the most common one.The main clinical manifestation was fever(n=23).Laboratory tests showed anemia [hemoglobin(85.78±25.47)g/L],hypoalbuminemia [albumin 29(27-32)g/L],elevated erythrocyte sedimentation rate [(85.73±43.78)mm/h] and hypersensitive C-reactive protein [(112.00±70.90)mg/L],and reduction of lymphocyte count [0.69(0.29-2.10)×10 /L].Lymphocyte subset analysis indicated reduction in CD4 T cells [213(113-775)/μl],CD8 T cells [267(99-457)/μl],B cells [39(4-165)/μl],and NK cells [88(32-279)/μl] and elevation of human leukocyte antigen-D related(HLA-DR),and CD38 expression in CD8 T cells [HLA-DR CD8 /CD8 ,60(40-68)%;CD38 CD8 /CD8 ,81(65-90)%].The most common species of NTM was Mycobacterium intracellular(n=6).Lymphocyte,CD8 T cell,B cell,and NK cell counts were significantly lower in dead patients than surviving patients(P =0.045,P=0.045,P=0.032,and P=0.010,respectively). Conclusions Disseminated NTM disease in HIV negative patients is mainly manifested as fever,anemia,hypoalbuminemia,and elevated inflammatory indicators.It is more likely to occur in immunocompromised patients.Patients with decreased lymphocytes,CD8 T cells,B cells and NK cells tend to have a poor prognosis.

PURPOSE: We aimed to study clinicopathological parameters and complications of patients who underwent magnetic resonance imaging-transrectal ultrasonography fusion guided prostate biopsy (MRI-TRUS FGB). MATERIALS AND METHODS: We investigated 576 patients who underwent MRI-TRUS FGB of prostate from May 2003 to December 2017 retrospectively. The clinicopathological features and complications were presented, using the modified Clavien-Dindo classification system. RESULTS: Fourteen patients (2.4%) readmitted within 30 days after MRI-TRUS FGB due to complications, and 85.7% (12 of 14) of them complained mild to moderate complications, the Clavien-Dindo classification grades I and II. The most common complication was hematuria (n=5, 0.9%), followed by acute urinary retention (n=3, 0.5%), dysuria (n=2, 0.3%), fever (n=1, 0.2%), hematochezia (n=1, 0.2%). According to multivariate analysis, only age was the significant risk factor of overall complications and bleeding related complications. Two hundred thirteen patients were diagnosed as prostate cancer after MRI-TRUS FGB. When the Likert suspicious scale of prostate cancer on apparent diffusion coefficient (ADC) was ≤4, 27.8% (137 of 493) were diagnosed as prostate cancer, of whom 56.2% (77 of 137) were confirmed as prostate cancer only at randomized 12 cores. When the ADC suspicious level was grade 5, 91.6% (76 of 83) were diagnosed as prostate cancer, of whom 11.8% (7 of 76) were confirmed as prostate cancer only at randomized 12 cores. CONCLUSIONS: The present study demonstrates the safety of MRI-TRUS FGB in terms of complications. When ADC suspicious level is grade 5, MRI-TRUS FGB alone could be a reasonable measure to diagnose prostate cancer, but randomized 12-core prostate biopsy would be recommended additionally when ADC suspicious level is ≤4.

PURPOSE: Familial Mediterranean fever (FMF) is an auto inflammatory disease characterized by periodic fever, synovitis and serositis. Patients may be admitted to gastroenterology units due to gastrointestinal symptoms. In this study; we aimed to analyze endoscopic findings and diagnostic utility of endoscopic procedure in children with FMF. METHODS: Patient with FMF that was performed endoscopy for the gastrointestinal symptoms were included to the study (39 of 164 patients, 53 procedure). A control group was randomly designed as age and gender matched four endoscopic procedures per one endoscopic procedure of patients with FMF (n=212). RESULTS: No different was found between the patients and control group in esophagogastroscopy findings. However, the diagnosis of gastrointestinal pathology was made by esophagogastroscopy in 46.2% patients. Colonoscopic examination revealed that the frequency of inflammatory bowel disease (IBD) was higher in undiagnosed patients compared to both the control group (50.0% vs. 6.9%, p < 0.05, odds ratio [OR]:13.4 and 95% confidence inteval [95% CI]: 2.1–84.3) and the patients under colchicine treatment (50.0% vs. 8.3%, p < 0.05, OR: 11 and 95% CI: 0.8–147.8). Colonoscopic procedure that was made after the diagnosis was found to provide contribution by 16.7% in determining the etiology of the additional symptoms. CONCLUSION: Patients with FMF may be admitted to pediatric gastroenterology outpatient clinic prior to diagnosis or during the follow-up period. The frequency of IBD is high in undiagnosed patients with FMF. Endoscopic procedures may be helpful in these patients for the diagnosis accompanying mucosal lesions.
