Study on ecologic microorganisms in lesions of acute guttate psoriasis induced by upper respiratory tract infection / 天津医药

Objective To investigate the characteristics of lesions of acute guttate psoriasis induced by upper respiratory tract infection, and to compare the difference in the different species between patients and healthy controls. Methods A total of 11 cases of acute guttate psoriasis induced by upper respiratory tract infection and 11 cases of healthy control without skin lesions of any dermatosis were included in this study. The 16SrDNA sequencing technology was used for analyzing data. The aseptic cotton swabs were used for sampling. DNA extraction and quality inspection were then performed. PCR amplification, library construction, microbial gene extraction, purification and recovery process were also performed. Then the gene samples were sent to be sequenced and to annotate the species. Finally, the data were analyzed by α and β diversity analysis to find the differences in microbial species and the diversity of microbial community. LEfSe analysis was used to find the species with significant difference, and the results were verified by the rank test. Results There was no significant difference in α diversity analysis between the two groups. There was a trend of difference in β diversity analysis between the two groups. However, LEfSe analysis (LED Score was 4) and rank test (P＜0.05) found that acinetobacter was a statistically significant different species and played a major role in the lesions of acute guttate psoriasis. Conclusion The skin lesions of microbiota is developing from one steady state to another one in the primary or recurrent acute guttate psoriasis patients with the history of upper respiratory infection. The different species of acinetobacter may play a key role in this change. However there is no significant difference in the overall microbial community between two groups.

Current Status and Clinical Studies of Oriental Herbs in Sexual Medicine in Korea

Erectile dysfunction (ED) is one of the most common diseases among aging men. Although previous studies have shown that type 5 phosphodiesterase inhibitors (PDE5-Is) are very effective for the treatment of ED, many researchers are currently attempting to identify therapeutic agents from natural sources with comparable or better effects than PDE5-Is. Herbal medicine is thought to be advantageous because it is natural; moreover, it not only treats isolated symptoms, but also maintains general well-being. Furthermore, since newly created chemical compound libraries have limited structural diversity with regard to pharmaceutical agents, more attention has recently been paid to the ability of oriental herbs to enhance physical health, including sexual function. Herein, we review the current status of Korean preclinical or clinical studies of the application of oriental herbs to sexual medicine.

An Unexpected Course after Simultaneous Urethral Repair and Reimplantation of Penile Prosthesis in a Patient with a Urethral Stricture

We experienced the growth of urethral hair along the urethral stricture six years after simultaneous urethral repair and reimplantation of penile prosthesis (RPP) in a patient with a urethral stricture. We detected hair in the urethra with a stricture on the bulbous urethra. Further, we performed hair removal by using a pair of cystoscopic forceps and internal urethrotomy. Then, we performed RPP, and the patient voided well; the prosthesis worked very well and without any complications. One-stage urethroplasty with a pedicle island of the penile skin and RPP in a simultaneous stage may be an option for treating the long-segment urethral stricture in the penile prosthesis patient. However, we should pay attention to the urethral hair growth that can occur after urethral repair performed using a skin graft.

Clinical research of 24-hour double-probe pH-metry in the laryngopharyngeal reflux diseases / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To determine the clinical value of 24 h double-probe pH-metry for the diagnosis and treatment of laryngopharyngeal reflux (LPR).</p><p><b>METHODS</b>According to the pH-metry results (whether the reflux events record in the upper esophagus is more than 6.9), patients of refractory pharyngolaryngitis were divided into LPR and control groups (each of 17 cases). All patients treated with anti-acid therapy and conventional pharyngo-laryngitis therapy. Correlation between pH-metry and the reflux symptom index (RSI), the reflux symptom index (RFI) were analyzed. Changes of the RSI and RFI in different group were calculated in post-treatment.</p><p><b>RESULTS</b>In the LPR group, the median reflux events of the upright time were higher than the supine time (Z = -3.62, P < 0.01), but the difference was not discovered in the control group (Z = -0.60, P > 0.05). There was no statistical difference between RSI, RSI and RFS with pH-metry, and with moderate concordance (k were 0.47, 0.53, P < 0.01, respectively). Compared to pre-treatment, the RSI and RFI were decreased both in LPR group and control group, Amplitude decreased in LPR group significantly higher than the control groups, with statistical difference (t were 3.74, 3.01, P < 0.01, respectively).</p><p><b>CONCLUSION</b>The 24 h double-probe pH-metry is significant for the anti-acid therapy of LPR.</p>
