Male infertility microsurgery represents the fastest growing sub-specialty in urology and clinical andrology over the past two decades. The importance of microsurgery for male infertility has risen as a part of the urologist's armamentarium in the medical and surgical management of male infertility. Despite the advances in male infertility microsurgery in China, the lack of standardized and well-organized training programs for male infertility microsurgery remains a serious problem affecting its development. In this article, Zhao and Peng have shared their experience with the learning curve of male infertility microsurgery at the Center for Male Reproductive Medicine and Microsurgery, Weill Medical College of Cornell University, which centers on how to pay attention to the details and basic principles of microsurgery. Male infertility microsurgery is physically, technically and mentally challenging, and must be first learned in the laboratory. Clinical success depends heavily upon appropriate training in a microsurgical laboratory. Good training can significantly reduce operation time and surgical errors as well as improve the quality of outcomes.

Objective: To evaluate the effect of several beverages on the physical properties of SonicFill (Kerr Corp.,USA), a new bulk-fill dental composite, over a period of time. Methods: A total of 28 discs (10 mm x 2mm) were prepared and randomly assigned into 4 groups (n=7) according to the beverages they wouldbe immersed in. The beverages chosen were Coca-Cola?, Nescafe? coffee, Lipton tea? and distilledwater (control). Surface roughness, microhardness and colour stability were evaluated using 3D opticalsurface texture analyser, Vickers microhardness tester and spectrophotometer respectively. Readingswere recorded at the time intervals of 24 hours, 1 week and 1 moth after immersion. The data obtainedwere analysed using one-way ANOVA, repeated measures ANOVA and MANOVA. Results: There weresignificant differences in surface roughness for only two pairs of groups (distilled water and Coca-Cola,distilled water and coffee). However, there was no significant difference between the groups within thechosen time. Statistical analysis showed significant difference in microhardness between time only forCoca-Cola, with significant differences between 24 hours and 1 week; and 24 hours and 1 month. Forthe colour evaluation, there was significant difference between the groups within time. Conclusions:All the beverages chosen were able to affect the physical properties of the SonicFill. However, noparticular beverage had a higher or lower impact on the surface roughness than the other beverages.Microhardness was affected by distilled water and Coca-Cola, in ascending order. Colour was affectedmost by coffee, followed by tea and Coca-Cola.

Aedes alboscutellatus was recorded first in Korea. This mosquito was collected near Demilitarized Zone of Korea Penninsula from 1979-1980. Its morphology and taxonomical position was described(abstracted from English content).

HIV/STIs remain a major global public health problem. One of the global strategies for the prevention and control of HIV/STIs is to interrupt their transmission, which requires the public health methods based on scientific evidence and cost-effectiveness. The scale-up of male circumcision services in the priority countries of the HIV-prevention project in sub-Saharan Africa has been hampered by the scarcity of trained providers and relative technical difficulty of male circumcision techniques recommended by WHO and UNAIDS. Shang Ring is an innovative and disposable device for male circumcision, which has been safely used for over 600 000 males in China since 2006. Clinical studies of more than 3 000 cases of Shang Ring circumcision in China, Kenya, Zambia, and Uganda have demonstrated its safety, effectiveness, acceptability and ease of use. The most obvious advantages of Shang Ring include short procedure time (3-6 min), excellent postoperative cosmesis, low rate of complications, high acceptance by clients and providers, ease of use, and standardization for reliable performance. As an innovative technique, Shang Ring has a great potential for facilitating the safe and effective scale-up of circumcision services. This article comprehensively reviews the clinical studies of Shang Ring male circumcision in China and Africa.

This is the case of a 71 year old male who developed multiple myeloma (MM) and chronic myelogenous leukemia (CML) within a two year period. The patient initially presented with osteolytic lesions of the lumbar spine, and following the initial work-up a diagnosis of multiple myeloma with an IgG kappa paraproteinemia was made and appropriate treatment was given. Two years later the patient developed a progressively worsening leukocytosis which was found to be due to Philadelphia Chromosome (Ph1) positive CML. The occurrence in the same patient of two distinct hematologic malignancies suggests a neoplastic transformation of a pluripotent stem cell. A review of the literature appears to support the existence of a relationship between MM and CML as well as a relationship between MM and the myeloproliferative disorders.

Verruca vulgaris of the larynx (VVL) is an extremely rare disease that can be easily misdiagnosed as papillary keratosis, squamous papilloma or verrucous carcinoma, which would have led to needless operation. We experienced a case of VVL in a 66-year-old man with 1-year history of progressive hoarseness. Whitish lesions in both vocal cords were observed by using indirect laryngoscopy and completely removed via microlaryngeal surgery with CO2 laser.

It is well recognized that the sensitivity of animals to lipopolysaccharide (LPS) endotoxin varies tremendously. And, it has been recently observed that Sprague-Dawley rats dramatically increase the activity of hepatic endogenous antioxidative enzyme systems after LPS administration. This finding suggests that the relative resistance of rats to LPS may be related to a concomitant increase in the activities of the hepatic antioxidant systems. This study was designed to examine if the above reported hepatic change in rats given LPS could be observed at the systemic level. Male Sprague-Dawley or Wistar rats, weighing 250 - 350 g, were given increasing doses (10 - 100 mg/kg) of LPS i.p. under 1.0% isoflurane anesthesia. Antioxidant capacity (AOC), blood gas analysis, and the cardiovascular parameters of the arterial blood of animals were determined over a 4 hour period following LPS administration. In addition, we studied the effect of pretreatment with the non-specific nitric oxide synthase inhibitor, L-N(G)-Nitroarginine methyl ester hydrochloride (L-NAME), given 50 mg/kg s.c. one and 24 hours before the administration of 20 mg/kg LPS i.p. in Sprague-Dawley rats. Rats given sufficiently high doses of E. coli LPS to produce behavioral effects also showed increased plasma AOCs in the early period after the administration of LPS. Similar changes were noted in Sprague-Dawley and Wistar rat strains, but at different doses that reflect their differential sensitivities to the LPS induced inflammatory response. Also, the resistance of the Sprague-Dawley strain of rats to LPS was not altered by the prior administration of L-NAME, nor was the plasma AOC altered. In conclusion, our study suggests that the rat strains are relatively resistant to develop the toxic signs of LPS in the early period after the administration of LPS, especially in Sprague-Dawley rats. Moreover, endotoxin-induced increases in plasma AOC may contribute to the rats' resistance to LPS intoxication.

Paranasal sinus mucoceles are an uncommon cause of isolated palsies of cranial nerves III, IV, and VI. The trochlear nerve has been reported to be less frequently affected than the abducens and oculomotor nerves. Isolated sphenoid sinus diseases may cause serious complications by involving adjacent vital structures such as the optic nerve, cavernous sinus, internal carotid artery, and cranial nerves III–VI. We report a case of a 76-year-old woman who presented to our emergency department with a chief complaint of acute double vision and headache. Her diplopia was diagnosed as left trochlear nerve palsy. Brain CT and MRI revealed expanding cystic lesions in both sphenoid sinuses with bony erosion of the left sinus wall. The patient underwent an endoscopic intranasal sphenoidotomy and recovered completely from diplopia at postoperative 2 months. The relationship between the trochlear nerve palsy and its anatomy is also discussed.

Methods: A prospective, single-center, consecutive cohort study was conducted over a period of 30 months. All new patients with low back-related disorders regardless of pathology completed a Yellow Flag Questionnaire that was adapted from the psychosocial flags framework. Clinicians assessing these patients completed a standardized form to determine which and how many yellow flags they had identified during the consultation. Results: A total of 130 patients were included in the analysis, and the clinicians reported an average of 5 flags (range, 0–9). Fear of movement or injury was the most frequently reported yellow flag, reported by 87.7% (n=114) of patients. Clinician sensitivity in detecting yellow flags was poor, correctly identifying only 2 flags, on average, of the 5 reported by patients, with an overall sensitivity of only 39%. Conclusions The ability of spine specialists to identify yellow flags is poor and can be improved by asking patients to complete a simple screening questionnaire.
