Electrodiagnostic evaluation in feline hypertrophic muscular dystrophy

Standard needle electromyography (EMG) of 56 muscles and nerve conduction velocities (NCV) of the ulnar and common peroneal nerves were investigated in each of six cats affected with hypertrophic feline muscular dystrophy, 10 related heterozygote carriers and 10 normal cats. The EMG findings were considered normal in carrier and control cats, and consisted of 33% normal readings, 22% myotonic discharges, 18% fibrillation potentials, 11% prolonged insertional potentials, 10% complex repetitive discharges and 6% positive sharp waves in affected cats. Muscles of the proximal limbs were most frequently affected. No differences in NCV were found between the three cat groups. It was concluded that dystrophin-deficient dystrophic cats have widespread and frequent EMG changes, predominantly myotonic discharges and fibrillation potentials, which are most pronounced in the proximal appendicular muscles.

Neuralgia of the glossopharyngeal nerve in a patient with posttonsillectomy scarring: recovery after local infiltration of procaine-case report and pathophysiologic discussion

We describe a patient with a three-year history of severe progressive left-sided glossopharyngeal neuralgia (GPN) that failed to adequately respond to various drug therapies. The application of lidocaine spray to the posterior pharyngeal wall provided no more than short-term relief. Apart from a large hypertrophic tonsillectomy scar on the left side all clinical and radiologic findings were normal. In terms of therapeutic local anaesthesia, the hypertrophic tonsillectomy scar tissue was completely infiltrated with the local anaesthetic (LA) procaine 1%. The patient has been almost completely pain-free ever since, and the lidocaine spray is no longer needed. Six weeks after the first treatment a repeat infiltration of the tonsillectomy scar led to the complete resolution of all symptoms. The patient has become totally symptom-free without the need to take any medication now for two and a half years. This is the first report of a successful therapeutic infiltration of a tonsillectomy scar using an LA in a patient with GPN that has been refractory to medical treatment for several years. A possible explanation may be that the positive feedback loop maintaining neurogenic inflammation is disrupted and "sympathetically maintained pain" resolved by LA infiltration.

The Rendez-vous technique for treatment of caesarean scar defects: a novel combined endoscopic approach.

BACKGROUND A caesarean scar defect is a late complication of caesarean birth with a wide range of prevalence between 56 and 84 % depending on which diagnostic tool and which definition is used [1]. The referred symptoms which include postmenstrual spotting and infertility are fortunately rare. Moreover, severe complications such as caesarean scar pregnancy and uterine rupture in the following pregnancy may occur. Given the increasing incidence of caesarean births, the potential morbidity associated with caesarean scars is likely to become more important. Recently, a few repair techniques were described in the literature including the hysteroscopic resection of scarred tissue or the laparoscopic repair with or without robotic assistance [2, 3]. METHODS Between June 2009 and February 2014, 21 women with caesarean scar defects were operated with the Rendez-vous technique, a minimally invasive surgery combining the laparoscopic and hysteroscopic approach. Data were retrospectively collected. The indications for this surgery included secondary infertility, previous caesarean scar pregnancy, recurrent miscarriage and postmenstrual spotting. Prior to operation, a transvaginal ultrasound was performed to examine the uterine wall defect. RESULTS The patient characteristics are provided in Table 1. In all cases, the operation was successfully completed laparoscopically. The median operation time was 125 min. One case was complicated by recurrence of the scar defect 6 weeks after the operation. No other intra- or post-operative complications were observed, and the median in-patient stay was 3 days. CONCLUSIONS The benefits of the technique include the feasibility and safety of the procedure, the "Halloween sign" (Fig. 1) which indicates the exact extent and localization of the scar defect and the immediate assessment of repair through the hysteroscopy at the end of the surgery. However, before further studies evaluate the efficacy of this method, the routine repair of caesarean scar defects cannot be recommended. A video of the technique is presented.

Laparoscopic Ultrasound-Guided Repair of Uterine Scar Isthmocele Connected With the Extra-Amniotic Space in Early Pregnancy.

We present a video of an ultrasound-guided laparoscopic surgical management of a large uterine scar isthmocele connected with the extra-amniotic space in early pregnancy. A case of a pregnant patient who was diagnosed with a large isthmocele connected with the extra-amniotic space on routine ultrasound at 8 weeks of gestational age is presented. The uterine defect was successfully sutured laparoscopically under ultrasound guidance. The pregnancy continued uneventfully, and a healthy baby was delivered via cesarean section at 38 weeks gestational age.
