RESUMO
A 65-year-old patient was admitted to the hospital due to proptosis of the left eye accompanied with ophthalmodynia and toothache for two months. Ophthalmic examination revealed a palpable mass around the lateral orbit and temporal fossa, and maxillofacial CT suggested a malignant tumor invading the left orbital floor wall. One week later, the patient was diagnosed with left orbital cellulitis and septic shock due to peri-orbit redness, eyelid edema, chest tightness, nausea, vomiting, hypotension, and a marked increase in peripheral blood neutrophil count. The infection was well controlled after remission of shock, anti-infective therapy and surgical drainage. At 2 months after surgery, the surgical incision of the upper eyelid skin recovered well and the best corrected visual acuity of the left eye was 1.0.

Longitudinal intussusception microsurgical vasoepididymostomy (LIVE) increases the patency rate in men with epididymal obstructive azoospermia (EOA). Here, we retrospectively analyzed the early outcomes of our modified single-armed suture technique for LIVE in men with EOA. From February 2012 to November 2013, 51 men received the modified technique and 39 men provided at least one post-operative semen sample. The mean age was 31.4 years old for the men and 29.2 years old for their female partners. The mean duration of obstruction was 34.3 months. Patency was noted in 24 (61.5%) men and pregnancy was reported in 15 (38.5%) female partners. Motile spermatozoa in the epididymal fluid were observed intraoperatively in 14 (58.3%) patent men and 3 (20%) non-patent men, respectively (p < 0.05). In the patent cohort, the mean ages of the pregnant and non-pregnant female partners were 26.5 and 32.7 years old, respectively (p < 0.05). Our modified technique resulted in favorable patency and pregnancy rates in this study. Sperm motility in epididymal fluid and female partner age were important factors associated with the patency and pregnancy rates.

BACKGROUND: Sevoflurane and remifentanil are commonly combined to produce the hypnotic and analgesic effects required for clinical anaesthesia. Previous studies have characterized interactions between several i.v. drugs and inhalation agents. Aiming to extend this effort, we developed two new mathematical models to characterize the interactions manner and strength between sevoflurane and remifentanil. METHODS: Sixty-five adult Chinese patients undergoing elective operations received a target-controlled infusion of remifentanil (0-10 ng ml(-1)) and inhaled sevoflurane (0.3-3.4 vol.%) at various randomly selected target concentration pairs. After reaching pseudo-steady-state drug levels, the circulatory response to laryngoscopy and any circulatory depression (a side-effect) were observed for each pair of target concentrations. The pharmacodynamic interactions between sevoflurane and remifentanil were investigated by response surface methodology. NONMEM software was used to estimate the model parameters. RESULTS: The response surface models revealed significant synergy between sevoflurane and remifentanil. When the target remifentanil concentration was increased from 0 to 10 ng ml(-1), the C50, sevo decreased from 2.6 to 0.38 vol.% for the prevention of circulatory response to laryngoscopy and from 3.53 to 1.46 vol.% for the induction of circulatory depression. CONCLUSIONS: The new models can be used to characterize the interactions between these two drugs both qualitatively and quantitatively. Remifentanil significantly decreased the amount of sevoflurane required to eliminate patient response to clinical stimuli, thus reducing the likelihood of side-effects, specifically circulatory depression.

The study investigated the psychosexual status and sexual function in adults who had hypospadias surgery at different ages. A detailed questionnaire was mailed to 130 patients who underwent hypospadias surgery between January 1988 and December 2007, and 50 healthy males who served as the control group. The patients were divided into three groups based on their age at which surgery was completed: group A (n=32; <10 years); group B (n=45; 10-18 years); and group C (n=53; >18 years). The Zung Self-Rating Anxiety Scale and The Zung Self-Rating Depression Scale were used to assess psychosexual status; a designed questionnaire and the International Index of Erectile Function-5 were used to assess sexual function. The incidence of anxiety and depression was significantly higher in patients than that in controls (P < 0.001), and was correlated with the age at which surgery was completed. The length and circumference of penises in patients were shorter than those of control groups with statistically significant differences (P < 0.01). There were no significant differences between patients and controls regarding libido strength, overall sexual satisfaction and erectile function (P > 0.05). In conclusion, difference existed in certain aspects of psychosexual and penile development between patients and controls. Hypospadias surgery should be performed early.
