Sporotrichosis Mimicking Rosacea Lesions: A Case Report.

Sporotrichosis is a subacute or chronic infectious disease caused by sporothrix. It is mainly caused by Sporothrix inoculation after accidental skin injury during human labor. The clinical manifestations of sporotrichosis are variable, ranging from nodules, plaques, ulcers, verrucous lesions, and subcutaneous masses. Some reports indicate that sporotrichosis can mimic psoriasis-like lesions. We herein report a case of sporotrichosis mimicking rosacea lesions. In addition, the patient had a history of nasal trauma, and we believe that the patient was inoculated with Sporothrix after the nasal skin was damaged during labor activities. The patient was given itraconazole 200 mg orally daily for 3 months, which effectively resolved the rash.

Should corticosteroids be administered for local infiltration analgesia in knee arthroplasty? A meta-analysis and systematic review.

WHAT IS KNOWN AND OBJECTIVE: The benefits of local infiltration analgesia (LIA) in knee arthroplasty (KA) have been well-documented. However, it is unknown whether adding a corticosteroid to the composition of the LIA is beneficial. This study aimed to investigate the efficacy and safety of administering periarticular steroids intraoperatively in patients who underwent KA through a systematic review and meta-analysis. METHODS: A systematic search was conducted to identify relevant randomized controlled trials in the PubMed, Embase, Web of Science and Cochrane databases up to January 19th, 2021 to perform a meta-analysis. Outcome variables included pain scores, total opioid consumption, knee range of motion (ROM) and postoperative complications. RESULTS: Corticosteroid injections did not reduce pain scores at 6, 12, 24 or 72 h postoperatively, although a minimal degree of transient pain relief was achieved at 48 h postoperatively compared with those in the placebo group, nor was there a significant difference in total opioid consumption. However, patients receiving corticosteroids did exhibit a transient ROM increase on postoperative days 1, 2 and 3. Since the minimal clinically important difference (MCID) for ROM is unclear, it is unknown if the improvement in ROM is clinically significant. WHAT IS NEW AND CONCLUSION: Our specific end-point analysis demonstrated that corticosteroid administration did not provide pain relief or reduce opioid consumption compared with placebo. However, corticosteroids might provide a statistically significant, though transient and minimal improvement in knee ROM after KA, although no firm conclusions about the benefits of administering corticosteroids in KA can be made based on the available evidence.

Prevalence and Genotype Distribution of Human Papillomavirus From 9,182 Individuals Participated Health Examination.

BACKGROUND: Human papillomavirus (HPV) is the cause of nearly all cervical cancers and the primary cause of anal cancers. Prevalence of HPV varies largely among countries and regions, and population-based data are largely insufficient. The aim of this study is to determine the prevalence and genotype distribution of HPV infection among the women received a general health check. METHODS: In the years 2015, 2016, and 2017, a total of 553,654 individuals received a general health check in the Sichuan Provincial People's Hospital. Among them, 9,182 unselected and asymptomatic individuals received the HPV screening test. Samples of exfoliated endocervical cells were collected and DNA isolation was performed with a Cell Lysis Kit. Fragments of HPV DNA were amplified by PCR. Twenty-one different HPV genotypes, including HPV 6, 11, 16, 18, 31, 33, 35, 39, 42, 43, 44, 45, 51, 52, 53, 56, 58, 59, 66, 68, and CP8304, were detected from PCR products using a GenoArray Diagnostic Hybridization Kit. HPV genotype was read on the colored position on the array. RESULTS: A total of 1,207 individuals were positive for at least one HPV genotype, giving a crude prevalence of 13.2% (95% CI: 12.5 - 13.9%). The prevalence did not differ much among age groups. HPV-positive individuals were 291, 389, and 527 in 2015, 2016, and 2017, respectively. The majority of the HPV-positive participants (960/1,207 = 80%) had one type of virus. Approximately 15% had two genotypes of HPV. One individual had HPV of 6 different genotypes, including 16, 18, 52, 53, 56, and CP8304. The most frequent genotype was 52, followed by CP8304, 58, and 53. The oncogenic types 16 and 18 were found in 112 and 52 participants, corresponding to a prevalence of 0.9% (CI: 0.8 - 1.1%) and 0.4% (CI: 0.3 - 0.6%), respectively, for the 9,182 individuals included in this study. CONCLUSIONS: The prevalence of 13.2% for HPV among unselected and asymptomatic individuals who received a general health check is high in the Sichuan area. Identification of high-risk HPV types is essential for preventing or early detection of cervical cancers and consequently save life.

[Efficacy of treatment with siRNA targeting Bcl-2 in combination with HCPT against transplanted H22 hepatoma in mice].

OBJECTIVE: To investigate the efficacy of treatment with siRNA targeting Bcl-2 in combination with HCPT against H22 hepatoma transplanted in mice. METHODS: siRNA targeting Bcl-2 mRNA was successfully designed and synthesized. Then, the Bcl-2 siRNA was transfected into H22 hepatoma transplanted in mice in combination with HCPT for treatment. The changes of tumor volume, body weight and survival rate were observed. Tumor tissues were processed into paraffin blocks and sections were stained with hematoxylin and eosin (HE) to investigate the morphological changes of the tumor cells. RT-polymerase chain reaction (PT-PCR) was used to assess the expression of Bcl-2 mRNA in tumors and cells. Cell cycle and apoptosis of H22 hepatoma cells transplanted in mice were further determined by flow cytometry. RESULTS: After treatment for 21 days, the tumor volume was around (571.47 ± 67.31)mm³ in the group of siRNA in combination with HCPT, which was significant smaller than that of the groups of HCPT [(880.47 ± 107.31) mm³, P < 0.05], siRNA interfere [(1119.55 ± 158.60)mm³, P < 0.01] and saline (1357.64 ± 197.92)mm³, P < 0.01]. The median survival time of the group receiving siRNA in combination with HCPT treatment was 26 days, which was significantly longer than that of the group receiving HCPT (14 day, P < 0.05), siRNA interfere (21 day, P < 0.05) and saline (12 day, P < 0.05). Larger necrotic area, lower expression of Bcl-2 mRNA, less cells at S phase and more apoptotic cells could be obviously seen in tumor tissues in the group of siRNA in combination with HCPT treatment. CONCLUSION: Bcl-2 siRNA in combination with HCPT has good synergetic antitumor efficacy in H22 hepatoma-bearing mice.
