Diplopia in orbital fractures: a simple method to evaluate eye motility.
This study on eye motility demonstrates a new application of electro-oculography which proved to have a high potential for establishing and diagnosing the cause of diplopia in orbital floor fractures. Electro-oculography is objective and easy to perform even when the restricted eye is covered. The 'uninjured' eye can be used as the reference. Any motility difference between the left and the right eye was easily detected. ⋯ Simulated entrapment was easily detected as a distinct difference between right and left eye motility recordings (p<0.001). Recordings of patients with diplopia differed significantly from those of healthy test subjects with respect to velocity (p<0.05) and range of motility (p<0.05).

Postoperative pain after paediatric adenoidectomy and differences between the pain scores made by the recovery room staff, the parent and the child.
The parents scored the postoperative pain higher than the nurse. The nurse's score correlated better than the parent's to the child's score. There was no gender difference regarding the pain after adenoidectomy. ⋯ The postoperative pain scores were higher at 10 min after the operation than after 30 min. The parents scored the pain higher than the nurse did, but there was still a strong correlation between the observers' rating of the pain. The correlation between the nurse's and the child's assessments was stronger than the correlation between the parent's and the child's assessments. There was no gender difference in how the pain was perceived by the child. The parents tended to score the pain higher with older age of the child.

Gentamicin ototoxicity: clinical features and the effect on the human vestibulo-ocular reflex.
Gentamicin ototoxicity presents with gait imbalance and oscillopsia, but only rarely with hearing loss and vertigo. Sinusoidal rotational stimuli with high accelerations such as the bedside head-thrust test or rotational step changes in velocity are useful to diagnose bilateral vestibulopathy. ⋯ All patients presented with imbalance and 33 out of 35 had oscillopsia. Three patients reported a noticeable change in hearing and five reported vertigo. Of the 35 patients, 15 were in renal failure at the time of gentamicin administration. Patients with pre-existing peripheral neuropathy compensated poorly. Sinusoidal rotational testing demonstrated profoundly decreased gain and increased phase lead over the entire frequency range, with a subset of patients having relatively preserved gain at the intermediate frequencies (0.8-1.6 Hz) and low acceleration (<30 degrees/s). There was little or no response to high acceleration step changes in velocity. The time constant measured both by sinusoidal and step responses was ultra-low. All patients tested had a positive head-thrust test bilaterally.

Risk of facial palsy and severe Frey's syndrome after conservative parotidectomy for benign disease: analysis of 610 operations.
Advanced age, long operation time and large specimen volume were significant risk factors for transient facial palsy after conservative parotidectomy. Revision operation was the only risk factor for development of a permanent palsy. Risk factors for Frey's syndrome were not found. The incidence of Frey's syndrome was not altered by the use of a sternocleidomastoid muscle flap or other implantation material. ⋯ The rates of transient facial palsies, permanent facial palsies and Frey's syndrome were 18%, 4%, and 4%, respectively. Significant univariate and multivariate risk factors for development of a transient facial palsy were age>70 years, operation time>260 min, and a specimen volume>70 cm3. The only significant risk factor for the development of a permanent palsy was prior surgery. A significant risk factor for the development of Frey's syndrome could not be estimated.

Case ReportsMucormycosis in an immunocompetent patient: follow-up of 1 year after treatment.
Mucormycosis is a rare acute fatal fungal infection. It is typically observed in diabetic or immunocompromised patients but not in systemically healthy individuals. ⋯ He was treated by surgery and removal of the necrotic bone and amphotericin B medication. At 1-year follow-up he shows complete recovery.
