Objective To investigate the diagnosis and management of AIDS patients accompanied with surgical diseases. Methods The clinical data of 40 AIDS patients accompanied with surgical diseases were analyzed retrospectively . Results Sixteen of the 40 patients with AIDS accompanied with surgical diseases were operated on,and the condition of the patients became better or cured after operation. Conclusions surgical operation is safe and beneficial to the AIDS patients accompanied with surgical diseases, if the operation is proformed in time.

Objective: To analyze the clinical features of death cases of dengue fever and the causes of their deaths. Methods: The clinical data and death reports of nine death cases of dengue fever in Guangdong Province from June 23, 2014 to September 10, 2019 were retrospectively analyzed. All of nine cases were positive for serum dengue virus RNA as confirmed by reverse transcription polymerase chain reaction, and some of the virus strains were serotyped. Results: The median age of the nine patients was 57.5 (range: 18-80) years. Among them, six patients were females; eight patients were local cases and one was imported case; all of nine cases occurred in September and October. The median time from onset to visit hospital and diagnosis was three and four days, respectively. Three of the nine patients had underlying diseases. All of nine cases had fever, including three with double-peak fever. Eight of the cases had three or more severe dengue fever warning indexes before admission. Three cases had severe bleeding upon admission, one case had shock, and six cases had organ failure. Three cases underwent invasive examination, including arterial puncture catheterization, endoscopic titanium clip hemostasis, and percutaneous transluminal coronary angiography. Two cases developed malignant arrhythmia and one had massive hemorrhage of subcutaneous soft tissue after operation. The death cases included four cases of cardiogenic shock and fatal arrhythmia, three cases of encephalitis and encephalopathy, one case of refractory shock, and one case of acute liver failure. Among the six cases that underwent serological typing, four were identified as dengue virus type 1 (DEN-1) and two were DEN-2. Conclusions Severe organ failure is the major cause of dengue fever-related death, especially fulminant myocarditis, and DEN-1 is most common. Early diagnosis and treatment, and avoidance of invasive procedures can effectively reduce the mortality rate of the severe dengue fever patients.

Objective To summarize and analyze the features of liver function in pediatric patients infected with Delta variant versus Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods In this study, an analysis was performed for the liver function test results of the locally transmitted or imported pediatric patients with SARS-CoV-2 infection during isolation who were admitted to Guangzhou Eighth People's Hospital, Guangzhou Medical University, since May 21, 2021, and the clinical data and the constituent ratio of liver injury were compared between the pediatric patients infected with Delta variant and those infected with Omicron variant. The independent samples t -test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. Results A total of 85 pediatric patients infected with SARS-CoV-2 were enrolled, among whom there were 32 (37.6%) pediatric patients infected with Delta variant and 53 (62.4%) pediatric patients infected with Omicron variant, and there were no significant differences between the two groups in age, sex, body height, body weight, and comorbidities (all P > 0.05). There were no significant differences between the two groups in alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase, total bilirubin, albumin, and cholinesterase (all P > 0.05), and the pediatric patients infected with Omicron variant had a significantly higher level of total bile acid (TBA) than those infected with Delta variant ( Z =-2.336, P =0.020). However, the median values of TBA were within the normal range and the ratios of abnormal TBA were no significant difference between the two groups ( P > 0.05). Among the 85 pediatric patients, 10 (11.8%) had a mild increase in liver function parameters, among whom 7 had an increase in TBA, 1 had an increase in ALT, 1 had increases in ALT and AST, and 1 had an increase in ALP. The analysis of liver injury in the pediatric patients infected with Delta variant or Omicron variant showed that there was no significant difference in the constituent ratio of liver injury caused by the two variants (6.3% vs 15.1%, χ 2 =0.691, P =0.406). Conclusion Mild liver injury is observed in pediatric patients infected with Delta and Omicron variants of SARS-CoV-2, but further studies are needed to evaluate the long-term influence of such infection on liver function.
