ABSTRACT

BACKGROUND: To study the association between sleep quality and oral health related variables, which still have conflicts in the literature. MATERIAL AND METHODS: This was a population-based case-control study between subjects with versus without sleep disorders from the Brazilian Public Health System (SUS), city of Maringá (N=1,643). Subjects answered self-reported questionnaires: a) Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), b) Sleep Assessment Questionnaire (SAQ) and c) North York Dental Health Survey (NYDHS). RESULTS: No significant difference was found for gender, marital status, or income; however, non-Caucasians, people with lower levels of education, and those between 20 to 50 years old had worse scores of sleep disorders in the SAQ. Self-perceived oral health, masticatory capacity to eat foods, and gingival bleeding was significantly worse among subjects with self-reported sleep disorders. Self-reported tooth loss, edentulism and use of removable partial dentures (with clasps) or complete dentures showed no significant difference between groups. Self-reported sleep disorder subjects presented significantly higher prevalence of both self-reported tooth and TMJ pain. CONCLUSIONS: It can be concluded that individuals with self-reported sleep disorders presented worse self-perceived oral health for most studied variables.

ABSTRACT

BACKGROUND: To evaluate the treatment efficacy of a mandibular advancement intraoral appliance (MOA) for treatment of obstructive sleep apnea syndrome (OSAS) in pediatric patients. MATERIAL AND METHODS: Eighteen patients (mean=8.39 years old, women=44.4%) were selected. Sleep disorders, sleep bruxism, and temporomandibular disorders were assessed by the Sleep Disturbance Scale for Children (SDSC), the BiteStrip® (portable SB device), and the Research Diagnostic Criteria for Temporomandibular Disorders, respectively. The clinical diagnosis of OSAS was confirmed with a type 3 portable monitor device (ApneaLinkTM Plus). A silicon-based material MOA was used by patients for 60 days, and the results were compared to baseline. RESULTS: The median RDI was significantly reduced from 10 to 4.5 events/hour. Nadir SpO2 significantly increased from 82.6% to 88.9%. Total snoring events/hour have also significantly decreased from 205.5 to 91.5. Signs and symptoms of TMD remained unaltered. There was also a reduction from moderate to absence of SB in 12 patients. Similarly, all variables measured by the SDSC have had very significant reductions: disorders of initiating and maintaining sleep, sleep disordered breathing, disorders of arousal, nightmares, sleep wake transition disorders, disorders of excessive somnolence, and sleep hyperhidrosis. CONCLUSIONS: In selected cases, OA maybe considered as an alternative for the OSAS treatment.

ABSTRACT

The objective of this study was to systematically evaluate gender differences in the prevalence of TMD. A systematic review was performed in PubMed, EMBASE, Web of Science and LILACS in duplicate by two independent reviewers. The inclusion criteria were cross-sectional studies that reported the prevalence of TMD for men and women and that used the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I group diagnostic criteria:(group I = muscle disorders; group II = disc displacements; group III = arthralgias/arthritis/arthrosis).To be eligible for inclusion, studies must include adult individuals (>18 years) from a non-clinical population (ie without pre-diagnosis of TMD); in other words, from population-based studies. There were no restrictions on the year and language of publication. The quality of the articles was assessed by an adapted version of the Newcastle-Ottawa Scale(NOS), and the publication bias was assessed by a funnel plot graph. Data were quantitatively analysed by meta-analysis using odds ratio (OR) as the measure effect. The electronic search retrieved a total of 6104 articles, of which 112 articles were selected for full-text reading according to the eligibility criteria. By means of manual search, one study was retrieved. Five articles were selected for meta-analysis with a combined sample of 2518 subjects. Women had higher prevalence of TMD in all RDC/TMD diagnostic groups. The meta-analysis yielded the following results: (a) OR = 2.24 for global TMD (groups I, II and III combined), (b) OR = 2.09 for group I, (c) OR = 1.6 for group II and (d) OR = 2.08 for group III. The importance of gender in the development of TMD has been demonstrated, with a two times greater risk of women to develop it as compared to men.

ABSTRACT

AIM: This registry study aimed to evaluate the effects of supplementation with pycnogenol on altered endothelial function (EF) in borderline hypertensive, hyperlipidemic and hyperglycemic subjects without atherosclerotic changes in their main arteries and no coronary artery disease. METHODS: Flow mediated dilatation (FMD) and endothelium-independent (EID) dilatation were measured with brachial ultrasound after occlusion. Also, after occlusion, laser Doppler (LDF) flux and distal straingauge flow were measured. Oxidative stress (oxstress) was evaluated at 8 and 12 weeks. 93 subjects with borderline symptoms were enrolled into the study: 32 hypertensives, 31 hyperlipidemics, 30 hyperglycemics. All participants were instructed to follow the best available management to control their symptoms. In addition to best management, half of the subjects in each group used 150 mg/day Pycnogenol(®). 31 normal subjects were included as control. RESULTS: After 12 weeks metabolic values and blood pressure were back to normal in all subjects. Values were slightly better under Pycnogenol(®). FMD increased after 8 weeks from an average 5.3;3.4% to 8.2;2.2% with a further increase to 8.8;3.1% (P<0.05) at 12 weeks. No effects were found in controls and normal subjects. EID of normal subjects was consistently higher with 26%. LDF skin flux increased with Pycnogenol(®) at 8 weeks and 12 weeks. The final flux increase was not different from normal values. In controls flux after occlusion was not improved at 8 weeks; there was a significant but minor increase at 12 weeks. Flux increases were superior in all Pycnogenol(®) subjects. In Pycnogenol(®) subjects, limb flow after occlusion increased at 8 weeks with a further increase at 12 weeks. In controls inclusion flow after occlusion was comparable at 8 and 12 weeks. Oxidative stress was significantly decreased in Pycnogenol(®) subjects at 8 and 12 weeks. Minor differences were observed in controls. CONCLUSION: This open registry study indicates that Pycnogenol(®) improves EF in preclinical, borderline subjects in a macro-microcirculatory model. This observation may suggest an important preventive possibility for borderline hypertensive, hyperglycemic and hyperlipidemic subjects.

ABSTRACT

Sixteen Italian Mediterranean Buffalo young bulls were divided into two groups fed isoprotein and isoenergy diets and only differing for protein source of concentrate: faba bean (FB) vs soybean (SB). Animals were slaughtered at 350 kg BW. Meat from FB group showed significantly lower fat, protein, cholesterol and saturated fatty acids than SB group. Significant differences were also found between the three muscles analysed [Longissimus thoracis (LT), Semitendinosus (ST) and Iliopsoas plus Psoas minor (IP)]. ST showed the most favourable fatty acids profile: lower SFA, higher PUFA, MUFA, ω-3, ω-6, CLA and, consequently, lower values for both atherogenic and thrombogenic indexes. Results showed that faba bean can be used as a protein source alternative to soybean in the diet of young buffalo bulls for the production of high quality meat.

ABSTRACT

This open, controlled study evaluated the effects of 6 month supplementation with Pycnogenol® maritime pine bark extract on health risk factors in subjects with metabolic syndrome. Pycnogenol® was used with the aim of improving risk factors associated with metabolic syndrome, central obesity, elevated triglycerides (TG), low HDL cholesterol, high blood pressure and fasting blood glucose. Sixty-four subjects (range 45-55 years) presenting with all five risk factors of metabolic syndrome were included, and Pycnogenol® was administered for 6 months. A group of 66 equivalent subjects were followed up as controls. In the 6-month study Pycnogenol® supplementation 150 mg/day decreased waist circumference, TG levels, blood pressure and increased the HDL cholesterol levels in subjects. Pycnogenol lowered fasting glucose from baseline 123 ± 8.6 mg/dl to 106.4 ± 5.3 after 3 months and to 105.3 ± 2.5 at the end of the study (p < 0.05 vs controls). Men's waist circumference decreased with Pycnogenol from 106.2 ± 2.2 cm to 98.8 ± 2.3 cm and to 98.3 ± 2.1 after 3 and 6 months. Women's waist decreased from 90.9 ± 1.6 cm to 84.6 ± 2.1 cm and to 83.6 ± 2.2 cm after 3 and 6 months. Both genders waist circumference reduction was significant as compared to controls at both time points. In addition, plasma free radicals decrease in the Pycnogenol group was more effective than in the control group (-34.6%; p < 0.05). In conclusion, this study indicates a role for Pycnogenol® for improving health risk factors in subjects with metabolic syndrome.

ABSTRACT

PURPOSE: Fear of cancer recurrence (FCR) is common and associated with younger age. This study aimed to explore the prevalence and correlates of FCR amongst younger survivors of early breast cancer. SUBJECTS: A total of 218 women aged 18-45 were diagnosed with stage 0-2 breast cancer at least 1 year earlier. METHODS: The participants completed a web-based survey including a validated measure of FCR and items exploring medical surveillance practices and health care use. RESULTS: A total of 70% of participants reported clinical levels of FCR. Higher FCR was associated with higher frequency of unscheduled visits to the GP, higher frequency of breast self-examination and other forms of self-examination for cancer, not having mammograms or ultrasounds or other forms of cancer screening in the past year, more complementary therapy use and the use of counselling and support groups. CONCLUSIONS: Young women with breast cancer are particularly vulnerable to FCR. The present study provides preliminary evidence that FCR is associated with higher health costs and lower surveillance rates which may compromise health outcomes. Routine screening for FCR in follow-up care is recommended.

ABSTRACT

Knowledge of the characteristics of the normal human aorta has been constrained by lack of data on fresh aortic tissue, especially from healthy individuals. In this study, the gene expression and morphological characteristics of the thoracic ascending aorta (AA) of healthy organ donors have been evaluated, with the aim of providing reference data for the analysis of pathological AAs. We analysed by RT-PCR the differential expression of mRNAs coding for myocardin, smoothelin, alpha-smooth muscle actin (alpha-SMA) and the ED-A isoform of fibronectin (ED-A FN) in AA specimens from donors, integrating the results with immunohistochemical analysis of the same targets. Morphological and morphometric characteristics of the AAs were also evaluated. In order to account for possible regional variations in wall structure, the convexity of the aortic profile was compared to the concavity. No differences in gene expression occurred for any of the target genes between the concavity and the convexity of AAs. Immunohistochemistry revealed a different distribution of total FN and of its ED-A isoform in the media and in the intima. Smoothelin is expressed by the majority of cells in the media, with some positive cells also in the intima. Alpha-SMA is expressed in all the tunicae. Immunohistochemistry also revealed in the convexity of 50% of AAs the presence of discrete areas in the subadventital media with altered structure and cell morphology and with altered gene expression, resulting positive for ED-A FN and alpha-SMA, but not for smoothelin, indicating the occurrence of early lesions also in macroscopically healthy AAs.

ABSTRACT

AIM: The simplification of the management of asthma in the different clinical phases of this common chronic inflammatory disorder is the main goal of therapy. Pycnogenol®, a standardized extract of French maritime pine bark, inhibits expression of 5-lipoxygenase and consequently decreases leukotriene levels in asthmatic patients. Pycnogenol® anti-inflammatory activities may be supportive when taken in addition to inhalation corticosteroid (ICS), putatively allowing for a reduction in dosage and frequency of ICS administration. METHODS: This study evaluated the efficacy of Pycnogenol® during a period of six months for improving allergic (mite in house dust) asthma management in patients with stable, controlled conditions. Pycnogenol® was used at a daily dosage of 100 mg, distributed as 50 mg in the morning at 9 am and again in the evening at 9 pm). An individual patient's asthma condition was graded in five steps based on the daily dosage of inhaled fluticasone propionate with step 1 indicating 0 µg and step 5 the maximum dose of 500 µg ICS twice daily. RESULTS: A total 76 patients were enrolled for this study. The group taking Pycnogenol® in addition to ICS and the group taking only ICS were comparable for age, gender and clinical characteristics including FEV1. The analysis of therapeutic ranking steps showed that 55% of patients taking Pycnogenol® improved as judged by passing to a lower ICS dose step. In comparison, only 6% of patients depending exclusively on ICS progressed to a lower (ICS dose) therapeutic step. No deterioration (passage to a higher ICS therapeutic step) was observed in the Pycnogenol® group, whereas in 18.8% of patients depending exclusively on corticosteroids a deterioration requiring a higher dosage step was observed. The passage to different therapeutic steps was statistical significant between groups (P<0.05). Drop-outs were associated entirely to irregularities in follow-up and not due to medical reasons. No serious adverse events were observed in both groups and tolerability of Pycnogenol® was very good. The levels of asthma control in the 6 interventional months as compared to the same period in the previous year were compared. In the Pycnogenol® group, night-awakenings were less frequent, the number of days with PEF<80% were decreased, days with asthma score >1 were lower, requirement for salbutamol and additional asthma medication less frequent, and consultation of general practitioner and specialist required less commonly. All these parameters were statistical significantly improved in Pycnogenol® + ICS group versus the ICS control group where no considerable changes were observed. Various common signs and symptoms were evaluated by visual analog scale, (dry) cough, severity of chest symptoms, wheezing, dyspnea and daytime symptoms. In the ICS-only group values did not improve while they did improve significantly in the ICS + Pycnogenol® group (P<0.05 vs. ICS only group). A decrease by 15.2% of the specific IgE titer was found in the Pycnogenol® + ICS group, whereas the titer increased by 13.4% in the ICS-only group, while IgG1 and IgG4 remained unchanged in both groups. CONCLUSION: Pycnogenol® administration was effective for better control of signs and symptoms of allergic asthma and reduced the need for medication.

ABSTRACT

AIM: Patients with tinnitus constitute a very large group without a real, specific therapeutic solution. With noninvasive, color duplex it is possible to measure flow in the cochlear artery and to follow duplex flow changes due to treatments in most patients. The aim of this preliminary evaluation was to study flow variations in patients with "mild-to-moderate" tinnitus, possibly associated to cochlear hypo-perfusion, after administration of Acustop (used as a food supplement). The aim was to improve cochlear flow decreasing the level of tinnitus. METHODS: Patients with "mild-to-moderate", "idiopathic", monolateral tinnitus, present for at least 4 weeks were included; no vertigo or important hearing loss had been observed. The origin of tinnitus had been sudden (hours or days). The tinnitus was associated to a decrease in cochlear flow measured by color Duplex at the affected ear. A group of 42 patients was evaluated; 25 used Acustop; there were 17 controls (follow-up only). Groups were comparable for their clinical problem and other details. The average duration of treatment was 4 weeks. RESULTS: No side effects were observed and no drop-outs were recorded. Flow velocity at the level of the affected inner ear was significantly lower (both the diastolic and systolic components; P<0.05) in comparison with the other ear. This was considered an indication of the vascular origin of the tinnitus. With Acustop treatment there was a significant improvement in systolic (P<0.05) and diastolic flow velocity (P<0.05). The increase in flow velocity was not significant in controls. An analogue scale line was used to measure symptoms in the Acustop group: it was 8.2;2 at inclusion; it decreased to 3.1;1.5 at 4 weeks (P<0.05). The score was 8.4;2 in controls at inclusion; at 4 weeks the score was 7.1;2.2 (not significant). Tinnitus scale: the value at inclusion of the tinnitus scale in the Acustop group a was 8.5;1.1 versus 8.3;1.2 in controls. After 4 weeks the score was 3.1;1.1 (P<0.05) in the Acustop group vs 7.2 in controls; the difference between the two groups was significant; P<0.025). CONCLUSION: In conclusion, these results suggest that in selected patients with tinnitus and altered inner ear perfusion Acustop appears to be effective in relieving tinnitus possibly by improving cochlear flow. More studies should be planned to evaluate better the potential applications of Acustop in this very interesting field. This clinical problem affects a large number of patients, without a real therapeutic solution at the moment, decreasing their quality of life and their performing abilities.

ABSTRACT

The aim of this study was to evaluate the efficacy of colostrum (ARD Colostrum) in association with the immunomodulator Bifivir in the prevention of flu episodes compared with anti-flu vaccination. The registry groups included no prevention, vaccination, vaccination+immunomodulators, and immunomodulators only. Groups were comparable for age and sex distribution. In the group without prevention there were 8 major episodes and 12 minor episodes out of 34 subjects (8-12/34); in the vaccination group the respective figures were 8-13/38; in the group treated with a combination of vaccination and immunomodulators (ARD Colostrum + Bifivir) the figures were 4-9/33; and in the group treated with immunomodulators only there were 11 viral episodes (3-8) in 36 subjects. The episodes in the vaccination+immunomodulators and immunomodulators only groups were significantly lower compared with the other two groups (P<0.05). The number of episodes registered with the immunnomodulators was significantly lower than those observed in patients using vaccination or no prevention (P<0.05). The number of days of disease was higher in untreated controls compared to the groups treated with immunomodulators (P<0.05) and 2 times higher in the vaccination group compared to the same groups (P<0.05). The average relative costs were significantly lower (2.3 times) in the immunomodulators groups in comparison with the other groups (P<0.05). No problems concerning tolerability or side effects were observed during the study. Compliance was very good. In conclusion, the administration of immunomodulators is very cost effective and appears to be more effective than vaccination to prevent flu.

ABSTRACT

Microbial screening is a primary concern for many products. Traditional techniques based on standard plate count (SPC) are accurate, but time consuming. Furthermore, they require a laboratory environment and qualified personnel. The impedance technique (IT) looking for changes in the electrical characteristics of the sample under test (SUT) induced by bacterial metabolism represents an interesting alternative to SPC since it is faster (3-12h vs. 24-72 h for SPC) and can be easily implemented in automatic form. With this approach, the essential parameter is the time for bacteria concentration to reach a critical threshold value (about 10(7) cfu mL(-1)) capable of inducing significant variations in the SUT impedance, measured by applying a 100 mV peak-to-peak 200 Hz sinusoidal test signal at time intervals of 5 min. The results of this work show good correlation between data obtained with the SPC approach and with impedance measurements lasting only 3h, in the case of highly contaminated samples (10(6) cfu mL(-1)). Furthermore, this work introduces a portable system for impedance measurements composed of an incubation chamber containing the SUT, a thermoregulation board to control the target temperature and an impedance measurement board. The mix of cheap electronics and fast detection time provides a useful tool for microbial screening in industrial and commercial environments.

ABSTRACT

AIM: In addition to contemporary compression therapy, one of the therapeutic approaches is the use of a topical wound care agent. The goal of this pilot registry study is to evaluate the efficacy and safety of a uniquely designed ointment containing multivalent silver oxide (Ag4O4) in the healing of difficult diabetic or venous ulcerations. METHODS: Patients who had ulcers resulting from chronic venous insufficiency or diabetes participated in this open-label, randomized registry study. All patients were evaluated by measuring both the area of the ulceration and microcirculatory parameters. 148 patients were included in the study and categorized into two main groups: venous ulcers and diabetic ulcers. Each main group was then randomized into two sub-groups: topical treatment with silver oxide ointment and the control group (standard cleaning and compression management methods, without silver ointment). All patients were treated with accepted cleaning and compression management. RESULTS. In subjects with venous ulcers: After 4 weeks, the silver treatment was more effective than the control group treatment: Skin PO2 was increased 2.1 times more than the control group (17.4% to 8.2%) and skin flux (RF) was improved 1.6 times more than the control group (-38.7% to -24.2%). The total surface area of the ulcer was significantly reduced in the silver treatment group by 1.9 times the control group (-88.7% to -46.9%). In addition, in the silver treatment group we observed complete closure of the ulceration in 42% of subjects compared to 22% in the control group (P=<0.05). In subjects with diabetic ulcers: after 4 weeks, the silver treatment was more effective than the control group treatment: Skin PO2 increased 2.6 times more than the control group (23.3% to 9.1%) and skin flux (RF) was significantly improved 4.3 times more than the control group(-26.7% to -6.2%). The total surface area of the ulcer was significantly reduced in the silver treatment group by 3.7 times the control group (-89.0% to -23.9%). In addition, in the silver treatment group we observed complete closure of the ulceration in 39% of subjects compared to 16% in the control group (P

ABSTRACT

AIM: In this study we investigated benefits of a Pycnogenol - coenzyme Q10 combination (PycnoQ10) taken as an adjunct to medical treatment in stable heart failure patients. The aim of this single-blinded, 12-week observational study was to provide functional parameters such as exercise capacity, ejection fraction and distal edema. METHODS: The essential element for inclusion was a stable level of heart failure within the past three months and stable NYHA class II or III (6 months). The heart failure management was in accordance with AHA guidelines for "best treatment." The treatment and control groups were comparable at baseline. The mean age of the PycnoQ10-treated patients was 61.3+/-7.1 years and 62.1+/-3.7 in the control group. All patients were taking medication and most patients (>75%) used three or more drugs for heart failure treatment. There were two dropouts in the PycnoQ10 treatment group and 6 in the control group (5 NYHA III patients). RESULTS: Nine PycnoQ10 treated patients (out of 32) and 3 (out of 21) taking placebo improved NYHA class. Systolic and diastolic pressure as well as heart rate and respiratory rate were significantly lowered with PycnoQ10 as compared to the control group (P<0.05). No significant changes were observed in controls. Heart ejection fraction increased by 22.4% in the treatment group (P<0.05) versus 4.0% in controls. Walking distance on treadmill increased 3.3-fold in PycnoQ10 treated patients (P<0.05) but marginally improved in the control group. Distal edema decreased significantly in PycnoQ10 treated patients and only slightly in controls. CONCLUSION: The association of Pycnogenol and CoQ10 may offer an important therapeutic option with a very good tolerability that improves heart failure management without side effects.

ABSTRACT

AIM: Based on the results of the soluble antioxidants test (SAT), we have produced a combination of oral antioxidants aimed at increasing the antioxidant power of saliva. Several antioxidants are included in this product (Vit E, beta-carotene, Vit A, Vit C, polyphenols, cathechins, ellagic acid, anthocyanins, coenzyme Q10 and pyridoxine in association with Se, Zn, L-cysteine). The aim of this registry study was to evaluate the efficacy of these antioxidants in saliva, plasma and urines. METHODS: MF Odontovis, an antioxidant complex, was administered to healthy subjects in the evening for one week with a final administration in the morning. RESULTS: Plasma, urine and saliva showed an increase in antioxidant power following both the evening administration and the final morning administration. The antioxidant action appeared to be present even at night when salival secretion is lower. Plasma SAT levels (SATs) in the morning following evening treatment were increased by 21% in comparison with controls. Morning administration increased levels up to 34% when measured 4 hours after treatment. Comparable increases were observed in saliva (SATs and morning values were +44 %; +58% two hours after morning administration and +28 % after 4 hours). In urine the evening administration caused an increase in antioxidant power (+6%). CONCLUSION: This study indicated that antioxidant levels can be increased with specific nutritional supplement. The clinical value of an increased antioxidant power in biological fluids, particularly in saliva, may be relevant for future trials of prevention and treatment.

ABSTRACT

AIM: A proprietary complex of curcumin with soy phosphatidylcholine (Meriva®, Indena SpA) was evaluated in a registry study to define its efficacy in 50 patients with osteoarthritis (OA) at dosages corresponding to 200 mg curcumin per diem. METHODS: OA signs/symptoms were evaluated by the WOMAC scores. Mobility was studied by walking performance (treadmill), and inflammatory status was assessed by measurements of C-reactive protein (CRP). RESULTS: After three months of treatment, the global WOMAC score decreased by 58% (P<0.05), walking distance in the treadmill test was prolonged from 76 m to 332 m (P<0.05), and CRP levels decreased from 168 +/- 18 to 11.3 +/-. 4.1 mg/L in the subpopulation with high CRP. In comparison, the control group experienced only a modest improvement in these parameters (2% in the WOMAC score, from 82 m to 129 m in the treadmill test, and from 175 +/- 12.3 to 112 +/- 22.2 mg/L in the CRP plasma concentration), while the treatment costs (use of anti-inflammatory drugs, treatment and hospitalization) were reduced significantly in the treatment group. CONCLUSION: These results show that Meriva® is clinically effective in the management and treatment of osteoarthritis and suggest that the increased stability and better absorption of curcumin induced by complexation with phospholipids have clinical relevance, setting the stage for larger and more prolonged studies.

ABSTRACT

AIM: The aim of this preliminary evaluation was to study the efficacy of Pycnogenol in improving cochlear flow in patients with mild-to-moderate tinnitus present for at least two weeks (without vertigo or important hearing loss), possibly associated with cochlear hypo-perfusion. METHODS: Patients with mild-to-moderate, idiopatic, monolateral tinnitus present for at least 2 weeks were included; no vertigo or important hearing loss had been found in a specific examination. The origin of tinnitus had been sudden (hours or days). Fifty-eight patients used Pycnogenol: 24 used 150 mg/day (group A; mean age 43.2+/-4.3) and 34 patients 100 mg/day (group B: mean age 42.4+/-3.8). Controls included 24 patients (mean age 42.3+/-4.5). The groups were comparable for their clinical problem and age and sex. The average duration of treatment was 34.3+/-3.1 days. No side effects were observed and no drop-outs occurred. RESULTS: The variations in cochlear flow velocity (in cm/s at the cochlear artery), at inclusion and after four weeks of treatment indicated that flow velocity at the level of the affected ear was significantly lower (both the diastolic and systolic components; P<0.05) in comparison with the other ear. The treatment favored an improvement in systolic (P<0.05) and diastolic flow velocity (P<0.05) in the two treatment groups A+B. The increase in flow velocity was very limited and not significant in controls. CONCLUSION: These results suggest that in selected patients with tinnitus and altered perfusion, Pycnogenol is effective in a short period of time in relieving tinnitus symptoms by improving cochlear blood flow. The effect is more pronounced with higher Pycnogenol dosage. More studies should be planned to better evaluate the pathology and potential applications of Pycnogenol in a larger number of patients who are currently without a real therapeutic solution.
