Childhood dizziness may take many forms; most often it presents as acute short-lived spinning attacks associated with headaches and nausea and less frequently as long-lasting symptoms with unsteadiness. Migrainous vertigo and middle ear infections are considered to be the most common causes of childhood dizziness, while head injury and pathology of the central nervous system are less common causes. We present a case history of a 10-year-old girl with acute positional vertigo attacks. Investigations and treatment demonstrated that this patient had canalithiasis variant Benign Paroxysmal Positional Vertigo (BPPV) in the lateral canal of the inner ear. The conventional view among many vestibular specialists is that childhood BPPV does not exist. We have demonstrated the opposite, and propose that childhood BPPV is more widespread than previously thought. We believe that children often spontaneously reposition dislodged otoconia through normal childhood play activities (e. g. tumbling, running, jumping, rolling etc.) thus avoiding the need to present for treatment with Epley and/ or Barbecue manoeuvres.

The objective of the study was to compare the efficacy of palanosetron (0.25 mg), granisetron (3.0 mg) and ondansetron (8.0 mg) used as anti-emetics for the prevention of postoperative nausea/vomiting in patients undergoing middle ear surgery. The study was done among 75 adult patients (age group 30-45 years) of which 50 were males and rest (25) females, all of ASA I and ASA II. The patients were randomly allocated into 3 equal groups: Group I (n = 25) received injection palanosetron (0.25 mg) IV, group II (n = 25) received injection granisetron (3 mg) IV and group III (n = 25) received injection ondansetron (8.0 mg) IV at the end of the surgical procedure. A standard general anaesthesia technique was employed. Emetic episodes and safety assessments were performed during two periods of 0-6 hours in the postanaesthesia care unit and 6-24 hours in the ward after anaesthesia. The incidence of emesis-free patients during the 0-6 hours period was 100% for group I; 72% for group II and 56% for group III. During the 6-24 hours period incidence of emesis-free patients were 96% for group I; 56% for group II and 32% for group III. So to conclude, a single dose of palanosetron (0.25 mg) is a superior anti-emetic to granisetron (3.0 mg) or ondansetron (8.0 mg) in complete prevention of postoperative nausea and vomiting after middle ear surgery during the first 24 hours period.

A 70 year-old man was admitted under the diagnosis of subarachnoid haemorrhage and presented with a history of ear pain, followed by acute onset of severe headache, nausea, vomiting, impaired consciousness, and fever. However, a computed tomography (CT) showed an acute mastoiditis and pneumocephalus, and a lumbar puncture confirmed the diagnosis meningitis. The increased middle ear pressure relative to the intracranial pressure had caused air and bacteria to penetrate intracerebrally. This case illustrates the importance of a rapid diagnostic workup in acute onset headache including a careful anamnesis, CT and lumbar puncture.

Actinomyces is a rare pathogen that can be the cause of infections in the digestive and urinary tracts, skin, genitalia, and lungs, which generally have an indolent clinical course. However, in some cases these can be locally destructive and become generalized infections. Actinomyces has been previously implicated in infections of the middle ear, nasopharynx, and sinuses, occasionally causing complications such as chronic mastoiditis. Here we describe the case of a 10-year-old-male presenting with nausea, vomiting, and headache who developed intracranial complications of actinomycotic mastoiditis.

Inner ear barotrauma can occur when the gas-filled chambers of the ear have difficulty equalizing pressure with the outside environment after changes in ambient pressure. This can transpire even with small pressure changes. Hypobaric or hyperbaric environments can place significant stress on the structures of the middle and inner ear. If methods to equalize pressure between the middle ear and other connected gas-filled spaces (i.e., Valsalva maneuver) are unsuccessful, middle ear overpressurization can occur. This force can be transmitted to the fluid-filled inner ear, making it susceptible to injury. Damage specifically to the structures of the vestibulocochlear system can lead to symptoms of vertigo, hearing loss, and tinnitus. This article discusses the case of a 23-year-old male Marine who presented with symptoms of nausea and gait instability after performing underwater pool competency exercises to a maximum depth of 13 feet, without breathing compressed air. Diagnosis and management of inner ear barotrauma are reviewed, as is differentiation from inner ear decompression sickness.

Objective First, to survey our national otolaryngology colleagues on their postoperative care habits (hospitalization vs day surgery) after elective middle ear surgery. Second, to evaluate the necessity of hospitalization and safety of day surgery after these procedures. Methods A national survey regarding postoperative habits after elective middle ear surgery was launched. Then, the cases of all patients having undergone these surgical procedures at our center between 2010 and 2016 were reviewed. They were divided into 2 groups: hospitalization and day surgery. Postoperative events during hospitalization and rate of consultation/readmission for day surgery were recorded. Results Heterogeneity in postoperative habits for most elective otologic surgery exists among otolaryngologists. For tympanoplasty, however, day surgery was uniformly favored. At our institution, 88.6% of hospitalization patients had no complications during their stay. Complications noted for others were nausea (7.2%), bleeding (3.1%), hematoma (0.5%), and sensorineural hearing loss (0.5%). In the day surgery group, 3.0% consulted within 48 hours following their procedure, and the readmission rate was 1.3%. Nausea was the only cause for readmission, and stapes surgery accounted for 100% of readmissions. Discussion Most elective middle ear surgery can be safely performed as day care. Hospitalization does not provide care that could not have been provided at home in the majority of cases. Overnight hospital stay may be considered for stapes surgery. Implications for Practice Day surgery for elective middle ear surgery is sufficient for most cases. Transferring these cases to day care should lower costs to our health care system and increase bed availability.
