Single‐port surgery: Current applications and limitations

Introduction: In an attempt to further enhance the benefits of cosmesis and reduced morbidity of minimally invasive surgery, single‐port (incision) laparoscopic surgery (SPS) has emerged as a bridge between conventional laparoscopy and natural orifice transluminal endoscopic surgery. As the expertise and instrumentation required are an extension of standard laparoscopic techniques, SPS has been adapted for a variety of procedures and specialties in a short span of time. Discussion: In this article, we discuss the various SPS techniques, as well as the new devices and instrumentation available for facilitating SPS. We also review current applications reported for SPS in various surgical specialties. We present a comprehensive review of the potential benefits, limitations and risks of these novel techniques. Conclusion: Initial reports have demonstrated the technical feasibility and safety of SPS for a wide range of surgical applications. With specialized instrumentation and refinement of technique, its role will increase in coming years. Future work is necessary to improve existing instrumentation, to increase clinical experience and to assess the benefits of this surgical approach.     

Alternate forms of selective reminding for children

Abstract

Two alternate forms of Selective Reminding were constructed according to criteria suggested by Kraemer, Peabody, Tinklenberg, and Yesavage (1983). The new forms, as well as the four-footed-animal version, were administered to 55 children aged 9- to 12-years-old from middle and lower socioeconomic groups. The two new forms were equivalent on two dependent measures of the Selective Reminding test. The results suggest that the two new alternate forms are equivalent and reliable for clinical use.     

Anal infections with concomitant <Emphasis Type="Italic">Chlamydia trachomatis</Emphasis>genotypes among men who have sex with men in Amsterdam,the Netherlands

Background  

Lymphogranuloma venereum (LGV) proctitis is caused by Chlamydia trachomatis (Ct) genotype L and is endemic among men who have sex with men (MSM) in western society. Genotype L infections need to be distinguished from non-LGV (genotypes A-K) Ct infections since they require prolonged antibiotic treatment. For this purpose, an in-house developed pmpH based LGV polymerase chain reaction (PCR) test is used at the Amsterdam STI outpatient clinic. We investigated retrospectively the anal Ct genotype distribution, and the frequency of concomitant genotype infections in MSM infected with LGV and non-LGV Ct infections. To detect concomitant Ct genotype infections, the pmpH LGV PCR and genoTyping Reverse Hybridization Assay (Ct-DT RHA) were used.     

Synthesis of carbon‐14‐labeled isotopomer of 6‐(4‐methanesulfonylphenyl)‐5‐[4‐(2‐piperidin‐1‐yl‐ethoxy)phenoxy]‐naphthalen‐2‐ol HCL salt (LY2066948‐[14C] HCL salt)

Carbon‐14‐labeled 6‐(4‐methanesulfonylphenyl)‐5‐[4‐(2‐piperidin‐1‐yl‐ethoxy)phenoxy]naphthalen‐2‐ol, a novel selective estrogen receptor modulator (SERM) was synthesized. The key component, 6‐methoxy‐1‐tetralone‐[carbonyl‐¹⁴C], was synthesized from 3‐(3‐methoxyphenyl)‐propionic acid via an intra‐molecular Friedel–Crafts acylation of 4‐(3‐methoxyphenyl)butanoic acid‐[carboxy‐¹⁴C]. A palladium catalyzed alpha‐keto arylation of 6‐methoxy‐1‐tetralone with 4‐methanesulfonyl‐phenyl bromide, followed by a sequence of bromination, DDQ dehydrogenation, aryl Ullmann reaction, and demethylation with BBr₃ gave the desired product LY2066948‐[¹⁴C].
