Dacryoadenitis associated with Acanthamoeba keratitis.

OBJECTIVE: To report the incidence of dacryoadenitis as a symptom associated with Acanthamoeba keratitis. METHODS: We investigated all cases of Acanthamoeba keratitis (20 patients and 21 eyes) diagnosed and treated at Tokyo Dental College, Ichikawa General Hospital, Ichikawa, Japan, between May 1, 1994, and November 30, 2005. We recorded the incidence of dacryoadenitis diagnosed using clinical signs of lacrimal gland swelling and pain on pressure, computed tomography, magnetic resonance imaging, and histopathologic analysis. RESULTS: Eight eyes (38%) of 8 patients had dacryoadenitis simultaneously with Acanthamoeba keratitis. Dacryoadenitis was diagnosed using histopathologic analysis and computed tomography in 1 patient, histopathologic analysis and magnetic resonance imaging in 1, magnetic resonance imaging in 2, and clinical signs alone in 4. Histopathologic examination in 2 patients revealed moderate infiltration of lymphocytes and plasma cells in the lacrimal gland compatible with dacryoadenitis. No Acanthamoeba organisms were found in the lacrimal gland. The standard protocol for Acanthamoeba keratitis was performed without particular treatment of dacryoadenitis in all patients. Lacrimal gland swelling improved after a mean of 10 weeks (range, 4-17 weeks) in conjunction with symptoms of keratitis; however, 1 patient (patient 1) required levator muscle surgery and blepharoplasty for residual ptosis. CONCLUSION: Dacryoadenitis is a clinical finding associated with Acanthamoeba keratitis.

Treatment of large conjunctival nevus by resection and reconstruction using amniotic membrane.

BACKGROUND: Nevus of the bulbar conjunctiva is a benign pigmented lesion of the ocular surface. Unless a biopsy is required for ruling out malignant melanoma, a nevus is usually excised for cosmetic reasons only. However, with large lesions involving two or more quadrants of the bulbar conjunctiva, a total resection can be difficult. In this report, we present a case of a huge nevus treated by surgical excision and amniotic membrane transplantation for reconstruction of the bulbar conjunctiva. METHODS: A 54-year-old Japanese man was referred to our clinic with suspected malignant tumor of the bulbar conjunctiva in his right eye. A large and diffuse pigmented tumor with numerous small cysts was present mainly on the upper bulbar conjunctiva. Resection of the conjunctival tumor and amniotic membrane transplantation for reconstruction of the bulbar conjunctiva were performed. RESULTS: The histopathological diagnosis was conjunctival nevus. Epithelialization of the bulbar conjunctiva over the amniotic membrane sheet was completed 4 weeks after resection. At 44-month follow-up, there was no recurrence or any postoperative complication. CONCLUSION: Surgical resection combined with reconstruction by amniotic membrane transplantation is effective for the treatment of large conjunctival nevus.

Grip strength in the frail elderly.

OBJECTIVE: To explore the relationship of impairment types to grip strength in the live-at-home frail elderly. DESIGN: All data in this cross-sectional study were collected in face-to-face interviews in subjects' homes by a nurse or occupational therapist. A total of 832 elders with activity limitations, as determined by the FIM instrument, participated in the study. Subjects were divided into three age groups (60-69, 70-79, and 80+ yrs) and four impairment groups: (1) minimally impaired, (2) visually impaired, (3) motor impaired, and (4) cognitively impaired. The outcome measures included the average (in kilograms) of three grip-strength trials per hand measured with the Jamar dynamometer at the second handle setting. RESULTS: There were significant differences in grip strength scores among all age groups, indicating that grip strength decreased with age. Among impairment groups, the minimally impaired and visually impaired groups had significantly greater grip strength scores than the motor-impaired and the cognitively impaired groups. There were no significant differences between the minimally impaired and visually impaired groups or between the motor-impaired and the cognitively impaired groups. CONCLUSIONS: Age and sex are not the only determining factors of grip strength in the frail elderly. The type of impairment affects grip strength as well. Thus, age-based norms may not be the only basis for interpreting evaluation data and establishing treatment goals with this population.

Dissatisfaction and nonuse of assistive devices among frail elders.

This article is based on the Rehabilitation Engineering Research Center on Aging Consumer Assessments Study. The sample included 1,056 subjects who reported use or nonuse of assistive devices. Of these subjects, 873 identified reasons for not using or being dissatisfied with certain assistive devices. Study participants owned a mean of 14.2 assistive devices, used 84.8% of the devices they owned, and were satisfied with 84.2% of the devices they owned. Devices were grouped into categories based on the type of impairment they addressed (hearing, vision, cognitive, and musculoskeletal/neuromotor). Study participants owned the largest number of devices in the musculoskeletal/neuromotor category (mean of 10.6 devices). Devices in the hearing impairment category were rated lowest by participants in terms of satisfaction. Almost half of all reasons listed for not using certain assistive devices related to perceived lack of need.

Problems with dressing in the frail elderly.

OBJECTIVE: Dressing is an important activity of daily living, yet many older adults have difficulty due to impairments. The purpose of this study was to explore the use of assistive devices for dressing by older persons with impairments, and to look at differences among frail elders with no dressing difficulty, upper-extremity-only dressing difficulty, lower-extremity-only dressing difficulty, and both upper- and lower-extremity dressing difficulty. METHOD: We conducted in-home interviews and functional assessments with 1,101 elderly persons with activities of daily living and/or instrumental activities of daily living limitations in Western New York and Northern Florida. Participants were assigned to one of four groups based on Functional Independence Measure item scores for upper-extremity dressing and lower-extremity dressing. Descriptive statistics were used to report results. RESULTS: Compared to women, there were relatively more men with lower-extremity dressing difficulty than with upper-extremity dressing difficulty. The group with both upper- and lower-extremity dressing difficulty reported the highest level of pain and scored lowest on all measures of functional status and mental status. The most commonly used dressing devices were associated with lower-extremity dressing. CONCLUSION: There are differences in gender, health status, functional status, and mental status among elderly persons grouped by upper- or lower-extremity dressing difficulty. Results suggest that therapists should consider such differences as gender and type of difficulty (upper- or lower-extremity dressing) in both therapeutic approaches and recommendations for assistive devices. Pain is another important consideration, but it can often be reduced during dressing by using assistive devices.
