[The interest of electroneuromyography in peripheral facial palsy].

In case of peripheral facial palsy, electroneuromyogram of the facial nerve provides an indication of the nature (myelinic and/or axonal) and severity of nerve damage, thereby facilitating establishment of a prognosis, which is favorable for myelin damage, and guarded for severe axonal damage. The initial examination must be carried out during the second week. In case of severe axonal damage, examination results can be monitored at the third, and more particularly the sixth and the twelfth months.

[Low circulating anti-Müllerian hormone and normal follicle stimulating hormone levels: which prognosis in an IVF program?].

Objective: To evaluate the results of controlled ovarian hyperstimulation (COH) for IVF in patients with low anti-Müllerian hormone (AMH) and normal basal follicle stimulating hormone (FSH) and Estradiol levels (≤50 pg/mL).

Patients And Methods: A retrospective cohort study including 704 patients for whom AMH and FSH levels (measured between days 3 and 5 of the menstrual cycle) were available, is performed in the IVF center at the Sèvres Hospital (France). Three groups are designed and analyzed: group 1 with AMH less or equal to 2 ng/mL and FSH less or equal to 10 mUI/mL (study group), Group 2 with AMH greater than 2 ng/mL and FSH less or equal to 10 mUI/mL (control group) and Group 3 with AMH less or equal to 2 ng/mL and FSH greater than 10 mUI/mL (group with decreased ovarian reserve).

[Management of upper obstetrical brachial plexus palsy. Long-term results of non-operative treatment in 22 children].

Introduction: Treatment of obstetrical brachial plexus palsy (OBPP) is always debated, especially for upper plexus palsy. Some authors perform early surgical treatment in case of absence of biceps contraction at the age of 3 months. Others prefer to wait until the age of 6 months before considering a surgical procedure when no suspicion of root avulsion is found.

Synthesis of hydrochloric acid solution for total mercury determination in natural waters.

Total mercury (Hg(T)) determination requires the addition of concentrated hydrochloric acid solution (≥10 mol L(-1) HCl) in relatively high amounts to preserve the samples and to prepare reagent solutions. A method for the preparation of concentrated HCl with Hg(T) concentration of lower than 5 ng L(-1) is described in this article. It is based on the well-known chemical reaction: 2 NH(4)Cl + H(2)SO(4) → (NH(4))(2)SO(4) + 2 HCl.

What is the place of electroneuromyographic studies in the diagnosis and management of pudendal neuralgia related to entrapment syndrome?

Entrapment of the pudendal nerve may be at the origin of chronic perineal pain. This syndrome must be diagnosed because this can result in the indication of surgical decompression of the entrapped nerve for pain relief. Electroneuromyographic (ENMG) investigation is often performed in this context, based on needle electromyography and the study of sacral reflex and pudendal nerve motor latencies.
