Comparison of the efficacy between transperineal ultrasound and endoanal ultrasound in diagnosing obstetrics anal sphincter injury / 中华超声影像学杂志

Objective:To study the agreements between transperineal ultrasound (TPUS) and endoanal ultrasound in assessing obstetrics anal sphincter injury (OASI), and to analyse the diagnostic efficacy of OASI in predicting AI relationship between OASI and anal incontinence (AI).Methods:A total of 217 women were prospectively recruited from the clinic in the Second Xiangya Hospital of Central South University from January 2021 to May 2022. Symptoms of AI were determined using the St Mark′s Incontinence Score (SMIS). TPUS and EAUS were performed by the same operator with the same machine on every participant for detecting OASI: OASI grades 3a, 3b, 3c, and 4 were performed according to the extent of the injuries in the anal sphincter complex. The angle of the defect in the external anal sphincter (EAS) was measured. A "significant EAS defect" was diagnosed as a defect affecting at least 2/3 of the length of the EAS with a defect angle of ≥30° in each slice.Ultrasound findings were compared between the two methods. The diagnostic efficacy of "ultrasound OASI" in predicting AI was analysed by logistic regression.Results:Of 217 women, twenty-eight (12.9%) suffered from AI with SMIS ranging from 5~20(11.9±4.5). On TPUS, 79 (36.4%) cases were suspected of OASI, that was 50 OASI 3a, 13 OASI 3b, and 16 OASI 3c/4. On EAUS, 78 (35.9%) cases were suspected of OASI that was 23 OASI 3a, 22 OASI 3b, 15 OASI 3c, and 18 OASI 4. Twenty-four "significant EAS defects" were diagnosed by TPUS and twenty-eight by EAUS, TPUS had excellent agreement with EAUS (weighted Kappa=0.91, P<0.001). Logistic regression analysis showed that "ultrasound OASI" was associated with AI symptoms. ROC curve analysis showed that the area under the curve (AUC) was 0.92, 0.87, 0.89, 0.92 for TPUS OASI 3b+ , EAUS OASI 3b+ , TPUS "Significant EAS defect" , and EAUS "Significant EAS defect" for predicting AI, respectively. Conclusions:TPUS has good agreement with EAUS in detecting OASI. OASI 3b+ and "significant EAS defect" on TPUS and EAUS had good performance in predicting AI symptoms.

Objective and significance of rotating to the department of medical imaging in standardized training of clinical pharmacists / 中华医学教育探索杂志

The rotation of clinical pharmacists in anti-infection specialty is an important part of standardized training. In view of the poor foundation of imaging diagnosis ability, short rotation time and unsystematic training scheme, the quality of standardized training has been significantly improved through strict management system, strengthening entrance education, reforming academic lecture mode, setting up tutorial system for training students and refining assessment system. It's of great significance for clinical pharmacists in the direction of anti-infection to understand systemic infection.

Analysis of Risk Factors of SkinAdverse Reactions by Intravenous Injection of Iodine ContrastAgent / 中国药房

OBJECTIVE：To investiga te main risk factors for adverse drug reactions （ADR）of skin by intravenous injection of iodine contrast agent. METHODS ：From Jan. 2009 to Apr. 2020，the patients suffering from skin ADR after enhanced CT with iodine contrast agent were collected from our hospital. The basic information ，laboratory test results before using iodine contrast agent and ADR related information were collected through hospital information system （HIS）. The use of iodine contrast agent ，main manifestations of skin ADR and drug combination were analyzed statistically. Taking the sex ，age，body mass index （BMI），the dosage of iodine contrast agent ，length of stay ，laboratory examination ，tumor history ，basic disease ，allergy history ，drinking history as independent variables ，the incidence of skin ADR related to iodine contrast agent was analyzed by single factor analysis ，and the variables with statistically significant were selected for multivariate Logistic stepwise regression analysis. RESULTS ：There were 157 cases of skin ADR ，involving 79 males（50.3％）and 78 females（49.7％）. The age ranged from 19 to 86 years old ，being（52.68± 18.73）years old in average. BMI was 14.6-40.7 kg/m2，being（22.5±3.7） kg/m2. 67 cases（42.68％）were treated with iprodione ，34 cases（21.66％）with iodixanol ，31 cases（19.74％）with iohexol and 25 cases（15.92％）with iopamidol ；the dose of iodine contrast agent were 50-100 mL，being（73.06±13.29）mL in average. There was no significant difference among different dosage of 4 kinds of iodine contrast agents （P≤0.05）. Among 4 kinds of iodine contrast agents ，the incidence of skin ADR induced by iopromide was the highest（0.197％）. The skin ADR related to iodine contrast agent was mainly acute （89.2％），the severity was mild （75.2％），and urticaria（38.9％）was the most common. After symptomatic treatment ，135 cases were cured ，13 cases were improved and 9 cases were not improved. Among the patients with iodine contrast agent related skin ADR ，the incidence of ADR induced by combined use of anti infective drugs was the highest （33.1％）；however，the combined use of anti-tumor drugs was the main cause of severe skin ADR. The length of stay ｛11～20 d[OR＝1.21，95％CI（1.07，1.20），P＝0.042]、21～30 d[OR＝1.39，95％CI（1.12，1.52），P＝0.035]、31～40 d[OR＝1.15，95％CI（1.03，1.37），P＝0.008]、＞40 d[OR＝1.33，95％CI（1.28，1.53），P＝0.003]｝，respitatory and circulatory system tumor history[OR ＝1.51，95％CI（1.35，1.61），P＝0.037]，injection allergy history[OR ＝1.50，95％CI（1.37，1.59），P＝0.005] can significantly increase the incidence of iodine contrast agent related skin ADR. CONCLUSIONS ：The main manifestation of skin ADR related to iodine contrast agent was urticaria. The main risk factors of skin ADR related to iodine contrast agent were length of stay （＞ 10 d），respiratory and circulatory system tumor history and injection allergy history.

Case Analysis of Participation of Clinical Pharmacists in Anti-infective Treatment for a Case of Septic Shock Induced by Intrauterine Infection / 中国药房

OBJECTIVE: To explore the role of clinical pharmacists in anti-infective treatment for the patient with septic shock induced by intrauterine infection. METHODS: Clinical pharmacists participated in anti-infective treatment for a patient with septic shock induced by intrauterine infection, and assisted physicians to formulate empirical anti-infective treatment, determine that Escherichia coli was pathogenic bacteria and analyze the causes of fluctuations in body temperature. According to the patient's disease condition and results of assistant examination, clinical pharmacists suggested using Imipenem and cilastatin sodium for injection 1. 0 g, ivgtt, q6 h, stopping Teicoplanin for injection, de-escalation using Cefoxitin sodium for injection 2. 0 g, ivgtt, q8 h for anti-infective treatment, with oral sequential therapy. RESULTS: Physicians adopted most advice of pharmacists. After 30 d anti-infective and symptomatic treatment, the patients symptoms were better than before, and discharged from the hospital. CONCLUSIONS: Clinical pharmacists participate in formulating individual anti-infective treatment regimen, so as to promote the rational use of antibiotics and improve the response rate and success rate of treatment.

Association of nocturnal serum cortisol level with diabetic microvascular complications in overweight/obese type 2 diabetic patients / 中华内分泌代谢杂志

Objective To explore the association of nocturnal serum cortisol levels with diabetic microvascular complications in overweight or obese patients with type 2 diabetes mellitus. Methods Serum cortisol levels of 316 overweight or obese type 2 diabetic patients were tested at midnight by the method of chemiluminescence. Diabetic microvascular complications were compared among various groups according to nocturnal serum cortisol levels. All the patients with nocturnal serum cortisol level > 50 nmol/L were asked to undergo overnight low-dose dexamethasone suppression test to rule out the possibility of subclincal Cushing's syndrome. The incidences of diabetic nephropathy ( DN ) , diabetic retinopathy ( DR ) , and diabetic peripheral neuropathy ( DPN ) were examined in all the patients. Results (1)The incidence of DN was gradually increased from 13.3％to 27.7％and 44.2％in patients with low, medium, and high cortisol level groups, showing a statistical difference among 3 groups ( P<0.05) . The incidences of DR in medium and high cortisol level groups were higher than that in low cortisol level group (40.6％and 47.7％vs 22.7％, both P<0.01). The incidence of DPN in high cortisol level group was higher as compared with low cortisol level group (60.5％ vs 38.7％, P<0.01). (2) Nocturnal serum cortisol level in patients with diabetic microvascular complications was higher than that in patients without complications [ (136.87 ± 105.78 vs 97.55 ± 93.48) nmol/L, P<0.01]. Nocturnal serum cortisol level in patients with multiple diabetic microvascular complications was higher than that in patients with single diabetic microvascular complication [ (151.66±114.54vs117.69±90.26)nmol/L,P<0.05].(3)Singlefactorlogisticregressionanalysisshowedthat higher nocturnal serum cortisol level was a risk factor for diabetic microvascular complications in addition to female, age, longer diabetic duration, higher fasting plasma glucose ( FPG ) . Multivariate logistic regression analysis showed that higher nocturnal serum cortisol level was still a risk factor for diabetic microvascular complications after adjusted by diabetic duration, FPG, HbA1C, and the use of insulin (P=0.013). Conclusion Nocturnal serum cortisol level seems to be a risk factor for diabetic microvascular complications in overweight or obese patients with type 2 diabetes mellitus.

Postoperative infection in laparoscopic cholecystectomy in treatment of acute cholecystitis complicated by choleperitonitis / 临床肝胆病杂志

Objective To investigate the influence of laparoscopic cholecystectomy (LC)versus open cholecystectomy (OC)on postopera-tive systemic infection and immune response in patients with acute cholecystitis complicated by choleperitonitis.Methods A prospective randomized controlled trial was performed for 45 patients who had a definite diagnosis of acute calculous cholecystitis complicated by cho-leperitonitis in Shanghai Liqun Hospital from January 2014 to June 2016.According to surgical procedures,the patients were randomized in-to LC group (23 patients)and OC group (22 patients).The length of hospital stay,postoperative complications,and deaths were evaluated in both groups.Blood samples were collected from all patients before surgery and at 1,3,and 6 days after surgery to compare the changes in neutrophil count,serum levels of C -reactive protein (CRP)and interleukin -6 (IL -6),and erythrocyte sedimentation rate (ESR),as well as the incidence of endotoxemia.The t -test was used for comparison of continuous data between groups,and the chi -square test was used for comparison of categorical data between groups.Results The LC group had a significantly shorter length of hospital stay than the OC group (5.4 ±2.7 d vs 10.2 ±3.5 d,t = -5.46,P <0.001).One patient (4.3%)in the LC group and 6 (27.3%)in the OC group ex-perienced peritoneal abscess after surgery,and there was a significant difference in the incidence rate of complications between the two groups (χ2 =4.77,P =0.03).In all patients,the mortality rate was 17.8% (8 /45),with 1 (4.3%)in the LC group and 7 (31.8%)in the OC group,and there was a significant difference between the two groups (χ2 =5.16,P =0.02).Of all patients in the OC group,4 died of peritoneal abscess,1 died of pulmonary embolism,and 1 died of myocardial infarction;of all patients in the LC group,1 died of my-ocardial infarction.There were no significant differences in inflammatory markers before surgery between the two groups.At 1,3,and 6 days after surgery,the LC group had significantly lower neutrophil count,serum levels of CRP and IL -6,and ESR (except at 1 day after surger-y)than the OC group (all P <0.05).Furthermore,the OC group had a significantly higher concentration of endotoxin than the LC group (P <0.05),but the level of endotoxin returned to normal at 2 days after surgery in both groups.Conclusion Compared with OC,LC can reduce the probability of endotoxemia,help with the establishment of immunological defense,and reduce the risk of postoperative infection.
