The effect of multilevel upper airway surgery on continuous positive airway pressure therapy in obstructive sleep apnea/hypopnea syndrome,,

THE LARYNGOSCOPE, Issue 1 2009
FACS, Michael Friedman MD
Abstract Objective: To investigate the effect of multilevel upper airway surgery (USA) on subsequent continuous positive airway pressure (CPAP) therapy in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS). Study Design: Fifty-two patients who underwent multilevel UAS with persistent symptoms of OSAHS represent the cohort for this study. All patients had undergone manual CPAP titrations both pre- and postoperatively. Patients were used as their own controls and were compared pre- and postoperatively with regard to body mass index, full night polysomnography (PSG), optimal CPAP pressure settings, presence of rapid eye-movement (REM) sleep, identification of mouth leakage, and CPAP compliance. Results: Postoperative values for apnea index (AI), apnea hypopnea index (AHI), and minimum oxygen saturation (min SaO2) were all significantly decreased from their preoperative levels. Compliance with CPAP therapy significantly increased from a mean 0.02 ± 0.14 hours per night prior to surgery to a 3.2 ± 2.6 hours per night following surgery (P < .001). In addition, the optimal CPAP pressure setting decreased significantly for a preoperative value of 10.6 ± 2.1 cm H2O to 9.8 ± 2.1 cm H2O following surgery. Fifty of the 52 patients (96.2%) studied were able to maintain optimal pressure settings without mouth leak, postoperatively. Conclusions: In this study, most patients who had persistent symptoms of OSAHS after multilevel UAS did not have significant mouth leak that would preclude CPAP therapy. In this cohort of patients, CPAP pressure setting as well as compliance was significantly improved postoperatively. Laryngoscope, 119:193,196, 2009 [source]


Changes in hip spasticity and strength following selective dorsal rhizotomy and physical therapy for spastic cerebral palsy

DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 4 2002
Jack R Engsberg PhD
Hip adductor spasticity and strength in participants with cerebral palsy (CP) were quantified before and after selective dorsal rhizotomy (SDR) and intensive physical therapy. Twenty-four participants with cerebral palsy (CP group) and 35 non-disabled participants (ND controls) were tested with a dynamometer (CP group: mean age 8 years 5 months, 13 males, 11 females; ND group: mean age 8 years 6 months, 19 males, 16 females). According to the Gross Motor Function Classification System (GMFCS), of the 24 participants with CP, eight were at level I, six were at level II, and 10 participants were at level III. For the spasticity measure, the dynamometer quantified the resistive torque of the hip adductors during passive abduction at 4 speeds. The adductor strength test recorded a maximum concentric contraction. CP group spasticity was significantly reduced following SDR and adductor strength was significantly increased after surgery. Both pre- and postoperative values remained significantly less than the ND controls. Spasticity results agreed with previous studies indicating a reduction. Strength results conflicted with previous literature subjectively reporting a decrease following SDR. However, results agreed with previous objective investigations examining knee and ankle strength, suggesting strength did not decrease following SDR. [source]


Open flap debridement with or without intentional cementum removal: a 4-month follow-up

JOURNAL OF CLINICAL PERIODONTOLOGY, Issue 9 2005
Antonio Wilson Sallum
Abstract Objectives: The aim of this study was to investigate the influence of cementum removal on periodontal repair. Material and Methods: Forty subjects with chronic periodontitis and presenting, at least, two proximal sites in anterior teeth (upper or lower) with probing depth 5 mm were selected. After oral hygiene instructions and ultrasonic supragingival instrumentation, the subjects were randomly assigned for one of the following groups: CIC, scaled with Gracey curettes; CIUS, scaled with ultrasonic device; CDC, calculus deattachment with Gracey curettes and brushing with saline solution; and CDUS, calculus deattachment with ultrasonic device and brushing with saline solution. Full-thickness flaps were reflected and the instrumentation was performed with a clinical microscope. Probing depth (PD), relative gingival margin level (RGML) and relative attachment level (RAL) were registered at five experimental periods: baseline and 30, 60, 90 and 120 days postoperative. Results: All the approaches were able to markedly reduce the PD values from the baseline to the other evaluation periods (p<0.0001). The increase in RGML values was statistically significant only for the CDUS group. There were no statistically significant differences between the baseline and postoperative values in all groups for the RAL changes. The changes in RAL were statistically significant only among the groups CDC and CDUS (p<0.0001). Conclusion: The conventional scaling and root planing and the calculus deattachment were effective in reducing the probing depth values, regardless of the instrumentation method. [source]


Vestibular Effects of Cochlear Implantation,

THE LARYNGOSCOPE, Issue S103 2004
Craig A. Buchman MD
Abstract Objectives/Hypothesis: Cochlear implantation (CI) carries with it the potential risk for vestibular system insult or stimulation with resultant dysfunction. As candidate profiles continue to evolve and with the recent development of bilateral CI, understanding the significance of this risk takes on an increasing importance. Study Design: Between 1997 to 2001, a prospective observational study was carried out in a tertiary care medical center to assess the effects of unilateral CI on the vestibular system. Methods: Assessment was performed using the dizziness handicap inventory (DHI), vestibulo-ocular reflex (VOR) testing using both alternate bithermal caloric irrigations (ENG) and rotational chair-generated sinusoidal harmonic accelerations (SHA), and computerized dynamic platform posturography (CDP) at preoperative, 1-month, 4-month, 1-year and 2-year postimplantation visits. CI was carried out without respect to the preoperative vestibular function test results. Results: Specifically, 86 patients were entered into the study after informed consent. For the group as a whole, pair wise comparisons revealed few significant differences between preoperative and postoperative values for VOR testing (ENG and SHA) at any of the follow-up intervals. Likewise, DHI testing was also unchanged except for significant reductions (improvements) in the emotional subcategory scores at both the 4-month and 1-year intervals. CDP results demonstrated substantial improvements in postural sway in the vestibular conditions (5 and 6) as well as composite scores with the device "off" and "on" at the 1-month, 4-month, 1-year, and 2-year intervals. Device activation appeared to improve postural stability in some conditions. Excluding those patients with preoperative areflexic or hyporeflexic responses in the implanted ear (total [warm + cool] caloric response , 15 deg/s), substantial reductions (,21 deg/s maximum slow phase velocity) in total caloric response were observed for 8 (29%) patients at the 4-month interval. These persisted throughout the study period. These changes were accompanied by significant low frequency phase changes on SHA testing confirming a VOR insult. Of interest, no significant changes were detected in the DHI or CDP, and there were no effects of age, sex, device manufacturer, or etiology of hearing loss (HL) for these patients. Conclusions: Unilateral CI rarely results in significant adverse effects on the vestibular system as measured by the DHI, ENG, SHA, and CDP. On the contrary, patients that underwent CI experienced significant improvements in the objective measures of postural stability as measured by CDP. Device activation in music appeared to have an additional positive effect on postural stability during CDP testing. Although VOR testing demonstrated some decreases in response, patients did not suffer from disabling vestibular effects following CI. The mechanism underlying these findings remains speculative. These findings should be considered in counseling patients about CI. [source]

ACTA OPHTHALMOLOGICA, Issue 3 2010
Joon Ho Roh
Abstract. Objective:, To evaluate the efficacy of the fluorescein dye disappearance test (FDDT) and measurement of tear meniscus height (TMH) in the diagnosis and postoperative assessment of nasolacrimal duct obstruction (NLDO). Methods:, The study group included 42 eyes of 42 patients who had a diagnosis of primary acquired nasolacrimal duct obstruction (PANDO) or functional nasolacrimal duct obstruction (FNDO) and underwent endoscopic transnasal dacryocystorhinostomy. The control group included 38 eyes of 38 people without tearing. The values of the FDDT, TMH and tearing symptom score (TSS), which was evaluated in five levels based on patients' history taking, were measured before surgery, and 1 day, 2 weeks, 1, 3 and 6 months after surgery. The values of the FDDT, TMH and TSS in the study group were compared with those of the control group. Results:, The preoperative values of the FDDT, TMH and TSS were 0.7 ± 0.4, 0.22 ± 0.08 mm and 1.6, respectively, in the control group and 3.0 ± 0.8, 0.53 ± 0.15 mm and 4.4, respectively, in the study group. These differences were statistically significant. Also, at each follow-up, the postoperative values of the FDDT and TMH decreased significantly compared to their preoperative values in the study group. The postoperative TSS decreased significantly compared to the preoperative values at each follow-up except at postoperative 1-day follow-up. There were no significant differences in the preoperative values of the FDDT, TMH and TSS between the types of NLDO. The TSS had positive correlations with the FDDT and TMH before and after surgery. Conclusion:, These results suggest that the FDDT and TMH measurement might be effective in the diagnosis and postoperative assessment of NLDO. [source]


Colour contrast sensitivity in cataract and pseudophakia

ACTA OPHTHALMOLOGICA, Issue 5 2000
Björn Friström
ABSTRACT. Purpose: To study the influence of cataract on peripheral and central colour contrast sensitivity. Methods: Peripheral and central colour contrast sensitivity was measured with a computer graphics system along the protan, deutan and tritan axes. Included were 30 patients with cataract divided into three sub-groups: cortical cataract, nuclear sclerosis and posterior subcapsular cataract. Colour contrast was measured before and after cataract operation. Results: There were significant differences in peripheral colour contrast thresholds comparing the preoperative and postoperative results. This difference existed even in patients (n=19) with a pre-operative visual acuity ,0.5 (mean 0.6). The tritan axis was the one most affected by cataract. There was no significant difference between cataract sub-groups. Also, the central colour contrast sensitivity was affected by cataract. Again, the tritan axis was the most affected one. There was no significant difference between the cataract sub-groups. We also found large and significant differences in central colour contrast thresholds between normal subjects and postoperative values from the cataract group in all colour axes. The colour contrast sensitivity was poorer in pseudophakes than in normals. There was a difference between the three groups of different IOL material used (PMMA, acrylic and silicone). The difference was significant in the protan axis, the acrylic group having the best colour contrast sensitivity. Conclusion: Peripheral colour contrast sensitivity was affected by cataract, even when only moderately developed. This finding is of importance and should be considered when the method is used to study other eye diseases e.g. glaucoma. Central colour contrast sensitivity was also affected by cataract. The pseudophakes were found to have poorer colour contrast sensitivity than normals. The material in the IOL seemed to be of importance for colour contrast. [source]


Quality of life before and after proctocolectomy and IPAA in patients with ulcerative proctocolitis , a prospective study

COLORECTAL DISEASE, Issue 2 2003
I. Berndtsson
Abstract Objective The principal aim of the present investigation was to study the general QoL and disease-specific adjustment before, and one-year after, operation with an ileal pouch anal-anastomosis (IPAA) in a consecutive series of patients with ulcerative colitis (UC). Patients and method Eleven patients were medically treated and 31 patients underwent colectomy with ileostomy. The patients were interviewed before the IPAA operation and again one-year after closure of the covering loop ileostomy. General quality of life was estimated with a Swedish instrument (according to Kajandi, score range 16,96) and a VA-scale. The instrument for disease-specific adjustment contained specific questions with five factors (score range 34,204). Open questions about quality of life were used to identify areas of concern, which were not included in the other instruments. Postoperative function was described in terms of a functional score (score range 0,15). Results The results of the general quality of life assessments did not differ significantly when comparing pre-operative to postoperative values. Disease-specific adjustment showed that the medically treated patients had a score of 162; interquartile range (IQR) 145,176. The patients with ileostomy scored 164; IQR 141,180. Postoperatively there was a statistically significant improvement in both groups to 189 (IQR 172,199), an increase of 15%. The open questions revealed restrictions in daily life for both patient groups pre-operatively with improvements after IPAA. The median grading of functional outcome according to the score system was 2. The most frequent problems were: patients who had occasional bowel movements at night, 40%; intermittent perianal soreness, 51%; antidiarrhoeal medication use, 61%. Conclusion General QoL did not change after IPAA. The bowel-specific adjustment in most factors improved in the majority of patients after IPAA. However, half of the IPAA patients had occasional bowel movements at night perianal soreness, and used antidiarrhoeal medication. [source]
