However quality cialis 2.5mg erectile dysfunction doctors fort lauderdale, a relatively large number of patients had discontinued Atripla due to CNS toxicity (Walmsley 2013) purchase cialis 20mg fast delivery vacuum pump for erectile dysfunction in dubai. Dolutegravir also performed very well in the FLAMINGO trial in which it was tested against darunavir (Clotet 2014). No resistance mutations were observed in cases of therapy failure. Treatment-experienced patients: In SAILING, a randomised, double-blind, non-inferi- ority study in 715 patients with a detectable viral load and with resistance to two or more classes of antiretroviral drugs, 50 mg dolutegravir QD were well tolerated with greater virological effect compared with 400 mg raltegravir BID. At 24 weeks, 79% versus 70% of the patients had achieved an undetectable viral load. Of note, significantly fewer patients had virological failure with treatment-emergent integrase- inhibitor resistance than on raltegravir (Cahn 2013). Even in the setting of INSTI resistance mutations, dolutegravir retains its efficacy. Preliminary data from the VIKING study showed that a higher dosage (50 mg BID instead of 50 mg OD) may help over- come raltegravir resistance (Eron 2013, Castagna 2014). Tolerance was excellent and better than with efavirenz, showing only a slight increase in creatine levels, which seems not to be significant and is caused by inhibition of a renal transporter system. The resistance barrier is possibly higher than with other integrase inhibitors, prob- ably due to prolonged binding with integrase complexes (Hightower 2011). Cross- resistance with other integrase inhibitors does not seem obligatory (Kobayashi 2011). An important resistance mutation appears at T124A, as well as mutations typical for raltegravir at codon 148. Efficacy seems to decline with Q148V and additional muta- tions (Canducci 2011, Garrido 2011, Castagna 2014). However, etravirine reduces the levels of dolutegravir significantly (Song 2011). This also applies for antacids and it is rec- ommended not to administer them simultaneously (Patel 2011). When rifampicin is given, a higher dose of dolutegravir seems necessary (Dooley 2012). Fortunately, there is no effect of food intake on resorption (Song 2012). Since its approval in 2014, dolutegravir has rapidly gained an important role in HIV medicine. Good tolerability, high resistance barrier, once-daily dosing and the absence of any booster requirements are major advantages. The coformulation with ABC+3TC, the first STR without tenofovir, is also very attractive. Elvitegravir (ELV, Vitekta, also part of Stribild) is an integrase strand transfer inhibitor developed by Gilead, with a biochemical similarity to chinolone antibi- otics (Sato 2006). In a study with 40 patients (ART-naïve and pre-treated), viral load decreased by 2 logs at 10 days of monotherapy (DeJesus 2006). In pre-treated patients there was a good effect when compared to a boosted PI (Zolopa 2010). A disadvan- tage is that elvitegravir must be boosted (Kearney 2006), but on the other hand a single administration per day seems possible. Stribild, a fixed-dose combination of the four Gilead substances tenofovir, FTC, cobicistat and elvitegravir in a single tablet, showed good efficacy in a phase II trial on therapy- naïve patients (Cohen 2011). Two large phase III trials investigating QUAD on therapy-naïve patients led to the approval of Stribild. In 236-0102, 700 patients received either Stribild, or Atripla (Sax 2012) and in 236-0103, 708 patients were treated with either Stribild or TDF+FTC+atazanavir/r (DeJesus 2012). After 48 weeks, 88% under Stribild (versus 84%) and 90% (versus 87%), respectively, achieved a viral load below 50 copies/ml. Both trials showed no difference in subgroups (sex, age, CD4 T-cell count, amount of viral load).

Selection of cases for the beginner There is no need to examine the patient under To attempt a case beyond ones capabilities is not anesthesia. If the fistula cannot be easily seen in the only demoralizing for the surgeon but a disaster for conscious patient using a Sim’s speculum then it is the patient, as the best chance of cure is always the not a simple case. Of all the new cases presenting only should confine themselves to: about one-quarter will be suitable for a beginner. History taking does not help that much in selecting • Small fistulae at least 4cm from the external the simpler cases. A small hole leaks just as much as urethral orifice. Cases not to attempt Some cases not to attempt as a beginner are shown in Figures 9–12. The scar tissue must be excised so a generous mobilization will be required to reach healthy bladder. The probe should be kept in the fistula during the dissection otherwise the track may be lost (a) (b) Figure 9 (a,b) This juxta-urethral fistula is pulled up behind the symphysis and adherent to bone, making access difficult. There is also complete separation of urethra and bladder (a small circumferential fistula). This requires an end-to-end anastomosis of bladder to urethra (a) (b) (c) Figure 10 (a–c) This is a juxta-cervical fistula which opens high into an open cervical canal. It is a challenging one to repair but has an excellent prognosis because the urethro-vesical junction is undamaged 248 Vesico-vaginal and Recto-vaginal Fistula (a) Figure 11 The defect in the vagina is so large that the (b) bladder has prolapsed but this is perfectly curable by a regular fistula surgeon A simple fistula repair, step by step See Figure 13 for a simple fistula repair. Another larger but simple fistula is illustrated in Figure 14. Bladder stones These are uncommon but can occur with small simple fistulae. It is essential to detect a stone at the start as it should be removed and the repair post- poned. Always use a metal catheter at the start to sound out the bladder. The feel and sound on tapping a stone is quite distinctive. Sometimes they can be suspected during the examination, as this Figure 12 (a,b) This is a large fistula high in the vagina may be uncomfortable.
