BACKGROUND: Malabsorption syndromes are known chronic complications of bariatric surgery. Therefore, it is recommended to take oral supplementation with multivitamins. Wernicke\'s encephalopathy represents an acute neuropsychiatric syndrome associated with alcoholism or severe malnutrition; sporadic cases of this potential complication related to bariatric surgery are described in the literature. We present a case of Wernicke\'s encephalopathy due to severe vitamin B1 deficiency after bariatric surgery.
METHODS: A 31-year-old woman with deaf-mutism from the age of 3 years old, operated 3 months before with a mini-gastric bypass for severe obesity, was transferred to our unit after accessing the emergency room. In the immediate medical history, there was the sudden and rapid decline in vision, leading to complete loss of vision, marked asthenia, and paresthesia in the four limbs. Considering the previous bariatric surgery, the diagnosis of non-alcoholic Wernicke\'s syndrome was suspected, for which IV therapy with Vitamin B1 was started at a dosage of 5 vials of 200 mg in 100 cc of saline solution (three times a day for the first 72 hours, subsequently 1 once/day). After 12 hours, there was an improvement in visual acuity, and the symptoms completely resolved within 48 hours. She was discharged with complete resolution of all symptoms after 1 month.
CONCLUSIONS: Initial vision loss without confusion or encephalopathy is one atypical presentation of Wernicke syndrome. Clinical suspicion must be high in case of alcoholism or post-bariatric surgery. Early recognition of atypical symptoms, including vision loss, and timely administration of therapy improves the prognosis of this potentially reversible but time-dependent neurological emergency.

If the term \"genetics\" is a relatively recent proposition, introduced in 1905 by English biologist William Bateson, who rediscovered and spread in the scientific community Mendel\'s principles of inheritance, since the dawn of human civilization the influence of heredity has been recognized, especially in agricultural crops and animal breeding. And, later, in familial dynasties. In this concise review, we outline the evolution of the idea of hereditary hearing loss, up to the current knowledge of molecular genetics and epigenetics.

BACKGROUND: Cochlear implants are now an acceptable therapeutic option for those patients with irreversible hearing loss and deaf-mutism. The surgery is time consuming and complicated. Hence, the technique of anaesthesia plays a crucial role in success of cochlear implant surgery. Cochlear implant patients have various types of syndromes which are important from anaesthetic as well as surgical point of view. Pre-implant preparation requires objective assessment of hearing, plain X-rays of skull and a CT scan of the temporal bone. Anaesthesia is required for objective assessment of hearing in children under five years of age, to obtain X-rays of skull, magnetic resonance imaging (MRI), CT scan, brain evoked response audiometry (BERA) testing and finally for cochlear implant surgery. Anaesthetic considerations include preoperative familiarisation with the patient and his family. Syndromal illnesses have specific anaesthetic significance such as presence of difficult airway or prolonged QT interval. Parental presence is highly desirable during induction of anaesthesia. Electro-surgical instruments especially monopolar ones, should not be used once the cochlear implant is in place.
METHODS: In our institution, all cases (15 children) received their cochlear implants under general anaesthesia and formed the study group. Children were administered midazolam orally and inj ketamine during CT scan. Our techniques of general anaesthesia were modified to permit use of nerve stimulators during surgery. To minimise the incidence of vertigo particularly after cochleostomy, postoperative nausea and vomiting, all patients received glycopyrrolate and fentanyl citrate intravenously prior to induction. Other agents used were, thiopentone, suxamethonium and end-tidal 1.3 MAC halothane in 1:2 mixture of oxygen and nitrous oxide (O2 and N2O). Electro diathermy was switched off, before the cochlear device was implanted on the patient. Patients were allowed to breathe spontaneously whenever nerve stimulator was used to locate the facial nerve. Inj Ondansetron 0.1 mg/kg was used as anti-emetic agent. Postoperative pain relief was initially provided with fentanyl 1 μg/kg IV and later with syrup ibuprofen.
RESULTS: There were no remarkable anaesthetic or surgical complication in our series except perilymph leakage in two cases.

The objective of this review is to remind the ENT community of the essential role of the French teams in the development and finalization of the multi-electrode cochlear implant (MCI), which has deliberately been neglected, and to repair the oblivion into which France was curiously cast at the end of the last century. It aims to underline significant scientific publications from the researchers who played key roles in the development of MCIs. In conclusion, the Parisian team of the ENT Lab in Saint Antoine Hospital in Paris can claim priority for its work in five regards. We were the first: (1) to plot in 1976 a frequency map of the whole length of three living human cochleas; (2) on September 22, 1976, to set up total cochlear implantation in a deaf adult male with eight electrodes; (3) on March 16, 1977, to apply for a patent for an implantable hearing aid in humans; (4) to describe sound signal processing (SSP) for a functional cochlear implant able to supply totally deaf patients with speech discrimination without the help of lip-reading; (5) in 1983, to experimentally demonstrate why it was necessary to place a cochlear implant as early as possible, in case of profound neonatal deafness. An injustice has occurred. These facts will be brought to the knowledge of the scientific community.

BACKGROUND: Speech-language pathologists/Otolaryngologists recognize high prevalence of speech and language disorder among children. The aim of the study is to find out the epidemiological profile of speech and language disorder in north central Nigeria.
METHODS: A five year retrospective review of all referral to speech and language therapy unit ENT Department between January 2005 and December 2009. Information retrieved and analysed included bio-data, clinical presentation and diagnosis of the patients. Descriptive analysis of these data were done.
RESULTS: A total of 146 patients were seen out of which 89 (61%) were under five, 32 (21.9%) were between 5-10 years, 20 (13.7%) in the range of 11-20 yrs and 2 (1.4%) were between 21-34 yrs. None was observed in the elderly. Male preponderance was noted with male to female ratio of 1.9:1.0. The commonest diagnosis was deaf-mutism in 84 (57.5%) followed by delayed speech development in 31(21.2%) patients. The least diagnosis was aphasia in 2 (1.4%) patients.
CONCLUSIONS: Speech and language disorder was commonest among the under five\'s with non in the elderly, There was a higher prevalence amongst males and deaf-mutism was the commonest observed.
