Background: The bone conductive implants (BCI) are nowadays a reliable alternative for rehabilitation of specific forms of hearing loss, i.e. conductive, mixed or single sided deafness (SSD).

Aims/Objective: To analyse the various factors in play when considering an auditory rehabilitation with a bone-conductive device (BCI).

Materials and Methods: The clinical charts of subjects who underwent BCI application at the same Implanting Center from 2005 to 2018 were retrieved analysing also the reason for eventual explantation and the alternative option (transition) for hearing rehabilitation.

Results: Nine BAHA Compact, 4 BAHA Intenso, 21 BAHA Divino, 3 BAHA BP100, 4 Ponto, 2 Sophono, 5 Bonebridge, 5 BAHA5 Attract; 11 BAHA5 Connect were used in 12 unilateral COM; 16 bilateral COM; 3 unilateral cholesteatoma; 6 bilateral cholesteatoma; 2 unilateral otosclerosis; 5 bilateral otosclerosis; 9 congenital malformations; 6 major otoneurosurgical procedures; 5 sudden deafness. Explantation was necessary for five subjects.

Conclusions: Middle ear pathology and sequels from surgery represent the most common reason for BCI implantation, both in unilateral and in bilateral cases. Transition from one implantable device to another one can be predictable, mostly when explantation is necessary.

Significance: The role of BCI for rehabilitation in middle ear pathology may be extremely important.  相似文献

A survey was carried out into the smoking habits and exposure to passive smoking among health staff in the hospitals of Faenza, Forli and Rimini (Emilia-Romagna, Northern Italy). 2453 subjects answered anonymously a 41 question questionnaire. 53% of the subjects were professional nurses, 16% doctors, 15% maintenance staff, 10% ancillary staff, 1% non-medical graduates, 2% were administrators and 3% were assigned to the category ‘others’.Of the subjects answering the questionnaire 39% were smokers, 19% ex-smokers and 42% non smokers. The highest number of smokers was found among women (41%) compared to men (37%) and among ancillary staff (48%) compared to nurses (41%) and doctors (31%). The males were mostly heavy smokers (≥20 cigarettes/d) and smoked strong cigarettes (≥12 mg/cig condensate content). The females were mostly light smokers (<10 cigarettes/d) and smoked light cigarettes (1–6 mg/cig condensate content). A high percentage of subjects (87%) smoked at work especially in areas reserved for staff. 43% and 26% of shift workers and non-shift workers tended not to modify their habit when on morning or afternoon shifts. During night shifts the majority of them increased their tobacco consumption.Around 87% of hospital employees stated they were exposed to passive smoking inside the hospital especially in cooking areas, at information desks and corridors. Nurses, ancillaries and maintenance staff were those most exposed and for a greater number of hours per day compared to doctors. Almost all subjects were aware of the harm caused by passive smoking. 56% of smokers, 65% of ex-smokers and 72% of non smokers said they were willing to participate in future campaigns to limit smoking in their hospitals.  相似文献

Pure red cell aplasia of pregnancy: a distinct clinical entity   总被引:1,自引:0,他引:1  
Summary. We describe a 31-year-old patient with pure red cell aplasia of pregnancy, successfully managed with regular blood transfusions. In vitro studies showed specific inhibition of day 14 erythroid colonies (BFU-E) using serum and purified immunoglobulin G (IgG) obtained from the patient at diagnosis (before blood transfusion). The inhibition of BFU-E disappeared when haematological remission occurred 3 weeks after delivery and she remains clinically well with a normal haemoglobin 4 years later.  相似文献

The authors report the cases of two patients with neonatal onset of hypoketotic hypoglycemia with hyperinsulinism and a poor response to diazoxide. Pancreatic venous sampling showed a diffuse pancreatic hyperplasia in one patient and a focal lesion in the other. The second patient, diagnosed after a significant delay, suffered severe long-term neurological sequelae, despite having more limited hyperplasia; the brain MRI also showed severe pathological changes in cortex and white matter, predominantly in the parietooccipital region. Early and accurate diagnosis is critical in these patients in whom hypoglycemia is compounded by a lack of the ketone bodies which represent a vital alternative source of energy for the central nervous system.  相似文献

Ten alcoholic Korsakoff patients and ten alcoholic control subjects were given several short-term memory, distractor type tasks in which consonant trigrams (verbal) and random shapes (nonverbal) were employed as the to-be-retained materials. The Korsakoff patients demonstrated a severe verbal memory deficit when the retention interval was filled with verbal distractor activity, but their retention of the same verbal material was intact when a nonverbal distractor task was used. In contrast, the Korsakoff patients' retention of nonverbal material was impaired regardless of the nature of the distractor activity. In fact, their retention of nonverbal material was impaired even when an unfilled retention interval was used.  相似文献
