Background: Noise-induced hearing loss (NIHL) is a prevalent hearing impairment, second only to age-related hearing loss. A change in the listening habits of adolescents may have contributed to the documented increase of hearing impairments in that age group.

Objectives: To examine the prevalence of NIHL among healthy young adults.

Methods: We conducted a retrospective study to examine audiograms of healthy candidates for the Israeli Air Force flight academy between 2018 and 2023. Hearing tests were performed by an expert audiologist using an audiometer.

Results: A total of 1940 audiograms were analyzed. The age range of the patients was 17–19 years. Using the British Society of Audiology classification, 174 (8.97%) audiograms and 313 frequencies were classified as impaired. The 8 kHz was the most affected frequency, accounting for 116 cases (37%).

Conclusions: Hearing impairment prevalence increased from 1% at entry into the education system to 8.45% at the end, respectively. Detecting hearing impairments early may minimize future disability and may reduce future disability and rehabilitation costs. Hearing screens for young adults due to the change in listening habits of adolescents may prove useful.

Background: Blast injuries impair hearing through several mechanisms that are distinct from other causes of acute acoustic trauma (AAT).

Objectives: To compare blast injured patients to those exposed to noise alone in their auditory response to hyperbaric oxygen (HBO) therapy with oral steroids.

Methods: Adult patients with evidence of a previously undocumented ≥ 30 dB pure-tone threshold within 30 days of AAT were treated with a combination of one 2.5 atm HBO therapy session for 90 minutes daily with oral prednisone. Exposure was classified by history as blast (for explosion-induced AAT) or noise. The change in high pure tone average (HPTA) was the primary outcome.

Results: Of 598 ears (387 patients) included in the final analysis, 259 were exposed to blast and 339 to noise. Before treatment, the blast injured patients had significantly more abnormal findings on otoscopy (87% vs. 95%, P = 0.003), higher pure-tone average (18 ± 11 dB vs 12 ± 9 dB; P < 0.001), and higher speech reception thresholds (16 ± 14 dB vs 10 ± 8 dB, P < 0.001). Following treatment, these patients exhibited a significantly smaller improvement in HPTA (6 ± 17 dB vs 10 ± 14 dB P = 0.022) with pure tone thresholds remaining significantly worse across all frequencies in the blast exposed group (mean difference ranging from 3.2 to 6.8 dB, all P < 0.05).

Conclusions: Blast injuries result in unique auditory characteristics and responses to HBO therapy compared to other causes of AAT.

We presented the emergent development of pulmonary hypertension and right ventricular impairment in a 64-year-old woman with metastatic breast cancer undergoing carboplatin–gemcitabine combination therapy. The patient's acute decompensation, characterized by dyspnea and desaturation, occurred 2 days after chemotherapy initiation. Clinical assessments revealed right ventricular dilation and systolic dysfunction, a rare manifestation not previously associated with the administered drugs, but which may be associated with cardiopulmonary toxicity of gemcitabine therapy. Prompt discontinuation of chemotherapy and initiation of diuretic therapy resulted in clinical improvement and resolution of the right ventricular dysfunction within several weeks. While a definitive causal link to gemcitabine remains inconclusive, this report highlights a potential and under-reported side effect, emphasizing the need for increased awareness and further investigation into the cardiopulmonary effects of gemcitabine.

Cognitive impairment due to different types of anemia is well-known. We reviewed the links between different types of anemia and the mechanism of cognition impairment as well as the direct involvement of micronutrients such as iron, vitamin B12, folic acid, and copper on cognitive function. Anemia can lead to cognitive impairment, yet the current health policy usually requires patient involvement in the treatment decision-making. Therefore, can an anemic patient be a partner to shared decision-making concerning the recommended treatment?

Background: Measurement of function is an essential component of routine rehabilitation work (mainly for quantifying function at different phases in the rehabilitation process), rehabilitation policy (admission and discharge criteria, length of stay in rehabilitation), goal setting, and outcome measurement.

Objective: To explore the scope of the scales used for function assessment by the various disciplines of rehabilitation medicine in rehabilitation facilities.

Method: A structured questionnaire was sent to 36 rehabilitation facilities. Respondents were asked to specify the scales they use for functional assessment for each of 15 selected pathologies. Also examined were satisfaction with the scales, as well as the existence of a computerized database of routine function assessment in the facility and the willingness to create a national agreed “common data set” of the assessments.

Results: The general response rate was 86.1% (31 of 36 questionnaires were returned). For the sake of data presentation, rehabilitation facilities were classified into four categories: general, geriatric, pediatric, and community. Most facilities performed function assessment using a total of 125 scales. Heterogeneity was found between facilities and between pathologies. The highest number of scales was found in the area of neurologic pathologies. For most pathologies, assessment of impairment was used more than assessment of disability. Most facilities in the survey did not have a computerized database of function assessments.

Conclusions: A “common data set” of function assessments in everyday clinical work would ensure standardization without necessarily limiting the use of additional scales and at the same time significantly minimize the current heterogeneity.
 

Background: The relationship between the amount of rehabilitation therapy and functional outcome in stroke patients has not been established.

Objectives: To evaluate the effectiveness of inpatient rehabilitation for post-acute stroke, and examine the relationship between intensity of therapies and functional status at discharge.

Methods: We evaluated 50 first-stroke patients, average age 63 years, in a prospective, descriptive study. The impairment and Functional Independence Measurement were assessed both at admission to rehabilitation and at discharge. Patients were monitored weekly during their stay by means of discipline-specific measures of activity level. Predictor variables included intensity of physical, occupational and speech therapies; demographic characteristics; length of stay; and time since the stroke.

Results: A significant reduction in impairment was observed at discharge. The predictors of gains and activity level at discharge as well as motor vs. cognitive components of the FIM[1] were neither consistent nor did they occur in the same trend of functional improvement. Greater FIM motor level at discharge was associated with younger age, higher admission motor and cognitive level, and receipt of any speech therapy, while greater FIM cognitive level was associated with higher cognitive level at admission, shorter interval from onset to admission, and more intense occupational therapy. More intense OT[2] was associated with greater and more cognitive improvement during the hospitalization.   

Conclusion: Since the sample was relatively small and heterogeneous in terms of the patients’ functional abilities, the findings cannot be generalized to the whole population of stroke patients. Further efforts to identify the best timing, modalities, intensity and frequency of the various treatments are needed to improve the cost-benefit equation of rehabilitation in stroke patients.
