ObjectiveTo analyze the clinical characteristics and pathogenesis in patients with chronic obstructive pulmonary disease (COPD) with ventilator-associated pneumonia (VAP). MethodsNinety-two patients with VAP who underwent mechanical ventilation via tracheal incubation due to COPD and respiratory failure were recruited in the study.The clinical characteristics,bacterial culture and antibiotics sensitivity of specimen from tracheal secretion and bronchoalveolar lavage fluid were retrospectively analyzed. ResultsThe main pathogenic bacteria in the patients with COPD with VAP were as following,ie. Ainetobacter baumanii(24.1%),Pseudomonas aeruginosa (17.6%),Klebsiella spp (15.9%),Methicillin-resistant Staphylococcus aureus(14.7%),and Escherichia coli(10.6%) in which Gram negative bacteria were predominant. When compared with the patients who received antibiotics before mechanical ventilation,the mortality in the patients who did not receive antibiotics before mechanical ventilation was significantly lower (17.9% vs. 40.6%,P<0.01). The patients who received de-escalation antibiotics therapy had lower mortality than those who received escalation antibiotics therapy(19.3% vs. 57.1%,P<0.01). There was no significant difference in mortality between the patients who suffered from VAP less or more than 4 days after mechanical ventilation (54.8% vs. 45.2%,P>0.05). ConclusionsHigh drug resistant rate is observed in patients with COPD and VAP especially in those patients who using antibiotic before mechanical ventilation. De-escalation antibiotics therapy can lower the mortality. The mortality rate is not significant different between early-onset and late-onset VAP in patients with COPD.
ObjectiveTo explore the clinical characteristic, operation time, and methods of elderly calculous cholecystitis. MethodsThe data of 386 cases of elderly calculous cholecystitis in our hospital from January 2008 to April 2014 were retrospectivly analyzed. ResultsIn 386 patients, 234 cases were chronic cholecystitis, 152 cases were acute calculous cholecystitis; there were preoperative complications in 174 cases (45.08%); 234 cases of chronic calculous cholecystitis patients underwent elective operation, 35 cases in 152 cases of acute phase underwent operation at 72 h, the remaining 117 cases underwent operation in within 2 weeks of onset. Laparoscopic cholecystectomy (LC) were in 283 cases, including transfer laparotomy operation in 8 cases; underwent conventional open cholecystectomy in 103 cases. Postoperative complications occurred in 49 cases, the complication rate was 12.69%, including incision infection, pulmonary infection, acute urinary retention, urinary tract infection, biliary fistula and so on. Three hundreds and eighty-four cases were cured, 2 cases died, for cholecystolithiasis complicated with severe acute cholangitis, died from multi organ failure in 3 days after operation. ConclusionsThe clinical characteristics of elderly calculous cholecystitis is unique. To strictly grasp the operation indication, selection of operation time, take individual operation method with the disease, and strengthen treatment of perioperative period are the key to improve the cure rate and the operation success rate of elderly cholecystitis.
Objective To summarize the cl inical characteristics of 596 patients with fracture in Wenchuan earthquake and to investigate the therapeutic methods and effects of early treatment. Methods From May 12th 2008 to May 21st 2008, 596 patients with fracture caused by Wenchuan earthquake were treated, including 283 males and 313 females aged1.9-102 years (median 43 years). The time from injury to hospital ization varied from 12 minutes to 4 days. There were 132 cases of upper extremity fracture, 496 cases lower extremity fracture, 10 cases clavicular fracture, 16 cases scapular fracture, 23 cases pelvis fracture, and 59 cases spinal fracture. Among them, 183 cases were open fracture and 413 cases were closed fracture. And 214 cases had multiple fracture (35.9%) and 68 cases had crush injury in l imbs which scored (6.84 ± 2.48) points according to the mangled extremity severity score (MESS). Thirty-six cases were combined with neurovascular injury. The wound of the open fracture was contaminated at different degrees, but no gas gangrene was observed. Open fracture was treated with suturing or no suturing after debridement, open reduction and internal or external fixation. Closed fracture was fixed with spl ints, cast and traction. Forty-nine patients whom were highly suspected as osseous fascia compartment syndrome received incision decompression timely, and 34 patients whose MESS were above 7.0 points or suffering from crush injury of l ifethreatening systemic symptoms received amputation. Results Apart from 34 patients receiving amputation, 460 patients achieved functional reduction of fracture after manipulative reduction and 102 cases got satisfactory reduction after surgery. Postoperatively, 289 patients were transferred to other hospitals. Among the rest 307 patients, 34 with severe wound infection were healed after multiple debridement, anti-infection, and skin flap transplantation (16 cases healed by first intention and 18 cases healed by second intention), 42 cases with crush syndrome were treated with open decompression and amputation, and nodeep venous thrombosis of lower l imb, stress ulcer and death were observed after operation (29 cases healed by first intention and 13 cases healed by second intention). Conclusion By aiming at the features of fracture caused by earthquake, the prompt and professional treatment can achieve good therapeutic effects.
ObjectiveTo retrospectively study the acute epileptic seizures of patients with anti-N-methyl-D-aspartate receptor (anti-NMDAR)and anti-leucine-rich glioma-inactivated 1(anti-LGI1)encephalitis. The characteristics and short-term prognosis provide reference for early clinical diagnosis and treatment.MethodsThe patients with anti-NMDAR and anti-LGI1 encephalitis who were admitted to the Department of Neurology of Sichuan Provincial People’s Hospital from January 2018 to June 2020 were continuously included. The general information, clinical manifestations, acute seizures and types of seizures were reviewed and analyzed.To evaluate the difference between the characteristics of two kinds of autoimmune encephalitis in the acute phase of seizures and the short-term prognosis.ResultsA total of 75 patients with anti-NMDAR encephalitis and anti-LGI1 encephalitis (41 males and 34 females) were included, of which average ages are(32.8±17.9)years, average courses are(1.8±1.1)months.59 and 16 are respectively positive for anti-NMDAR and anti-LGI1 antibodies, respectively. Of the 75 cases, 56 cases (74.7%) had seizures in the acute phase. Among the 56 cases of seizures, 38 cases (67.8%) were accompanied by disturbances of consciousness, 5 cases (8.9%) of autonomic dysfunction, and 24 cases of decreased oxygenation capacity. (42.9%) and 20 cases (35.7%) who were admitted to NICU, there was a significant statistical difference compared with the seizure-free group (P<0.05). The median age of anti-NMDAR encephalitis in the acute stage of seizures was 23 years, and that of anti-LGI1 encephalitis was 56.5 years (P<0.05). Anti-NMDAR encephalitis and anti-LGI1 encephalitis are common in the acute phase of epileptic seizures (55.9%vs.53.8%). Anti-NMDAR encephalitis has more frequent seizures and status epilepticus in the acute phase (P<0.05). After early and rational use of anti-epileptic drugs(AEDs) and immunotherapy and other symptomatic and supportive treatments, 70% of 56 patients were effectively controlled for seizure. Follow-up 3 months later, 18 patients (32.1%) stopped using anti-epileptic drugs (AEDs), While 30 patients (53.5%) continued to receive AEDs treatment, of which 25 patients (44.6%) had no seizures.ConclusionBoth anti-NMDAR encephalitis and anti-LGI1 encephalitis have a higher risk of seizures in the acute phase. Patients with seizures are more likely to have disturbances in consciousness, decreased oxygenation capacity, and higher rates of admission to NICU. Anti-NMDAR encephalitis is more common in young people around 30 years old, and anti-LGI1 encephalitis is more likely to develop around 60 years old. Patients with anti-NMDAR encephalitis are more likely to have abnormal electroencephalograms, have a longer average hospital stay, and are more likely to have recurrent seizures and status epilepticus in the acute phase. After timely diagnosis and intervention treatment, most patients' seizures can be well controlled. After the acute phase, AEDs can be withdrawed in one third of patients.
ObjectiveTo analyze the clinical and epidemiological characteristics of hospitalized avian influenza A (H7N9) virus infections in Hunan province from 2013 to 2017, and provide evidences for control, diagnosis and treatment of this disease.MethodsNinety-one hospitalized patients were confirmed with H7N9 infection in Hunan. Excluding 2 patients less than 18 years old and 10 with missing data, 79 patients with H7N9 infection were analyzed.ResultsMost confirmed cases were affected in the second and fifth epidemic wave and number of patients in the fifth wave was more than the sum in prior 4 waves. Epidemiological characteristics, clinical symptoms and case fatality did not change significantly. Administration of antiviral drugs was more active in the fifth wave [from illness onset to antiviral drug: (6.3±2.4)d vs. (7.6±2.4)d, P=0.047]. Multiple logistic regression analysis showed that shock (OR=4.683, 95%CI 1.136–19.301, P=0.033) was the independent risk factor of H7N9 infections. There were no significant differences in case fatality among group oseltamivir, group oseltamivir+peramivir, and group peramivir.ConclusionsPatients with avian influenza A (H7N9) increased in the fifth wave but clinical characteristics changed little. Antiviral treatment should be more active. Shock is an independent risk factor of H7N9 infections. Oseltamivir-peramivir biotherapy can not reduce case fatality compared with oseltamivir or peramivir monotherapy.
Objective To analyze the clinical characteristics and the treatment of 20 confirmed A/H1N1 flu cases of serious conditions. Methods The 20 confirmed A/H1N1 flu cases of serious conditions were collected and we analyzed their Clinical characteristics, treatment and prognosis. Results The 20 cases of serious conditions were given Oseltamivir, endotrachealintubation, ventilator ventilator assistant, high dose intravenous injection of Gamma-globulin/ albuminum/plasam of A/H1N1 flu rehabilitation, appropriate liquid recovery and hypothermic treatment, etc. A total of 19 of 20 confirmed A/H1N1 flu cases of serious conditions were cured and 1 case died. Conclusion The intent observation, early detection and early intervention are very helpful for A/H1N1 flu cases of serious conditions.
Objective To systematically review the prevalence, clinical characteristics, and prognosis of fulminant type 1 diabetes mellitus (F1DM) in China. Methods The CNKI, WanFang Data, CBM and PubMed databases were searched to collect Chinese F1MD case reports from January 1, 2000 to March 30, 2022. Data analysis was performed using Stata 16.0 software and RevMan 5.3 software. Results A total of 874 cases were included in 233 papers, involving 410 males (46.91%) and 464 females (53.09%). The age of onset was 29.32±1.09 years and the course of disease was 3.74±0.63 days. The BMI was 21.18±0.52 kg/m2, HbA1c was 6.58%±0.08%, the level of fasting C-peptide was 0.04±0.010 ng/mL, level of C-peptide 2 h after meal was 0.09±0.020 ng/mL, the level of blood glucose at the doctor’s office was 34.72±2.89 mmol/L, and the level of arterial blood gas pH was 7.09±0.015. Among them, 734 patients had diabetic ketoacidosis (84.55%), 496 patients had infection of the upper respiratory or digestive tract before onset (56.75%), 4 patients died (0.46%), 78 patients were GADA positive, 11 patients were ICA positive, 13 patients were IAA positive, and 109 were pregnant patients (90 fetal deaths, 82.57%). Conclusion Chinese F1DM is a special but common subtype of diabetes. Its characteristics include a relatively young age of onset, devastating islet damage, and rapid progression, and it is often accompanied by severe metabolic disorders, complications, and grim prognosis. Clinicians should pay more attention to F1DM.
ObjectiveTo strengthen the understanding to hypersensitivity pneumonitis and make early diagnosis and standard treatment by analyzing the clinical features, the diagnosis and treatment of a patient diagnosed as hypersensitivity pneumonitis presenting as progressive fibrotic interstitial lung disease in combination with literature review.MethodsThe diagnosis and treatment process and relevant clinical data of the patient were analyzed retrospectively and literatures were reviewed. Based on 282 relevant literatures, the diagnostic methods, treatment and prognostic factors of hypersensitivity pneumonitis were summarized.ResultsThe patient, female, 45 years old, self-employed, was admitted to the hospital due to "cough, sputum for 9 years, dyspnea for more than 6 months" without obvious extrapulmonary clinical manifestations. Creaks at the bottom of the lungs and clubbed toes were found through physical examination. High-resolution computed tomography indicated that the main manifestations were ground glass and grid-like shadows, presenting characteristics of interstitial pneumonia. The pulmonary lesions aggravated gradually, and part of the lung lobe presented honeycomb lung at the time of diagnosis. Eight years ago, she performed fibrobronchoscopy in other hospital revealing an increased lymphocyte proportion (39%) in bronchoalveolar lavage fluid. Lung function suggested very severe restrictive ventilation dysfunction. She was given prednisone for a short time, and the drug was stopped by herself with uncertain efficacy. Later, she performed frozen lung biopsy suggesting peribronchiolar metaplasia interstitial broadening with lymphocytic infiltration, without granuloma or fibroblast lesions. No obvious abnormity was seen in makers of infections and immunology. At this point, the patient was clearly diagnosed as hypersensitivity pneumonitis. Meanwhile, the patient's pulmonary lesions were still mainly made of ground glass and plaques, partly with changes like honeycomb. Poor response was obtained with anti-inflammatory treatment of prednisone for 3 months and anti-fibrosis treatment of pirfenidon for more than 2 months. Literature review resulted in 87 patients, including 39 males (44.82%) and 48 females (55.18%), with an average age of (47.0±18.4) years. Seventy patients (80.46%) had clear allergens. 3.45% patients' lymphocyte percentage in bronchoalveolar lavage fluid ranged from 20% to 39%, and 19.54% patients' lymphocyte percentage was more than 40%. 4.60% of the patients achieved remission through detachment from allergens; 71.27% of the patients achieved remission with glucocorticoid treatment, 14.94% improved with glucocorticoid treatment, and 1.15% died; 6.89% of the patients achieved remission after receiving anti-allergy therapy. Patients with chronic hypersensitivity pneumonia were found with poor prognosis.ConclusionsIn patients with diffuse interstitial pulmonary fibrosis with unknown cause, transbronchoscope freezing lung biopsy as early as possible is a feasible method for early diagnosis and improving prognosis. Patients with hypersensitivity pneumonitis with a long course of pulmonary fibrosis have a poor response to glucocorticoid and other classic treatments, and most of them have a poor prognosis.
Objective To analyze the clinical features and outcomes of pregnant women with acute diarrhea. Methods We collected the clinical data of 133 pregnant women with acute diarrhea (group A) admitted into Tangshan Maternal and Child Health Hospital and Kailuan General Hospital between June 2009 and June 2015. Another 100 acute diarrhea patients without pregnancy (group B) and 100 pregnant women without acute diarrhea (group C) were regarded as controls. All the patients’ medical history, symptoms and signs, laboratory examination results, diagnosis and treatment, termination of pregnancy and pregnancy outcomes were retrospectively analyzed. Results The average age of group A patients was (29.72±5.19) years old, and 83.46% of them came to hospital within 24 hours. There were significant differences in vomiting, abdominal pain, white blood cells, neutrophils, C-reactive protein, white blood cells in the feces, fibrinogen, prothrombin time, activated partial prothrombin time, thrombin time and the recovery time of the laboratory indicators between group A and group B (P<0.05). The neonatal weight of group A was lower than that of group C, and the difference was statistically significant (P<0.05). Regression analysis showed that hemoglobin and albumin had significant influence on acute diarrhea during pregnancy (P<0.05). Conclusion Pregnancy with acute diarrhea is a kind of severe obstetric complication, which may lead to adverse pregnancy.
ObjectiveTo investigate the clinical characteristics and prognosis of cerebral hemorrhage in young and elderly patients, to provide evidences for individual clinical diagnosis and treatment, and lay a foundation for building a predictive model of prognosis in cerebral hemorrhage.MethodsPatients with spontaneous cerebral hemorrhage in the Third People’s Hospital of Chengdu were recruited prospectively and continuously from January 2014 to January 2019. They were divided into the youth group (≤50 years old) and the elderly group (>50 years old), and their risk factors, disease characteristics, etiology, and prognosis were analyzed.ResultsA total of 757 patients were recruited. There were 160 cases (21.1%) in the youth group, including 120 males and 40 females, aged from 17 to 50 years, with an average age of (42.06±7.62) years old; 597 cases (78.9%) in the elderly group, including 361 males and 236 females, aged from 51 to 96 years, with an average age of (69.34±10.56) years old. The incidences of hypertension (74.2% vs. 51.2%), diabetes (15.1% vs. 4.4%), coronary heart disease (12.1% vs. 1.3%), and the level of blood glucose at admission [7.1 (5.8, 8.4) vs. 6.3 (5.3, 8.1) mmol/L] in the elderly group were higher than those in the youth group (P<0.05), respectively. However, the proportions of males (60.5% vs. 75.0%), smoking (24.5% vs. 36.9%), and the diastolic blood pressure at admission [(92.37±18.50) vs. (100.95±25.25) mm Hg (1 mm Hg=0.133 kPa)] in the elderly group were lower than those in the youth group (P<0.05), respectively. There was no significant difference between the two groups in systolic blood pressure at admission, Glasgow Coma Score, National Institutes of Health Stroke Scale score, initial hematoma volume, hematoma enlargement, brain hernia, location of hemorrhage, midline shift, hydrocephalus, combined subarachnoid hemorrhage, or intraventricular extension (P>0.05). Hypertension was the most common etiology in the two groups. There was a significant difference in the etiology of cerebral hemorrhage between the two groups (P<0.05), the difference was mainly reflected in cerebral amyloid angiopathy, cavernous hemangioma, and arteriovenous malformation. The fatality rate during hospitalization (9.4% vs. 20.9%), 3 months after discharge (10.3% vs. 26.3%), and at 1 year follow-up (19.0% vs. 37.6%) in the youth group was lower than that in the elderly group (P<0.05), respectively. The disability rate 3 months after discharge and at 1 year follow-up in the youth group was lower than that in the elderly group (32.1% vs. 44.2%, 16.9% vs. 34.4%; P<0.05), respectively.ConclusionsThe education of healthy lifestyles should be strengthened to reduce the adverse effects of smoking in young patients. Young patients should choose antihypertensives that can control diastolic blood pressure better. There are more structural abnormalities in young patients, so routine vascular examination is reasonable. It is necessary to focus on whether the original underlying diseases are stable in elderly patients. Cerebral amyloid angiopathy is an important cause of cerebral hemorrhage in elderly patients, and is a risk factor of recurrence. Anticoagulation or antiplatelet therapy should be cautious.
