Adjunctive benefits of systemic etoricoxib in non-surgical treatment of aggressive periodontitis: Short-term evaluation

Background: This pilot study assessed the effect of short-duration treatment with etoricoxib as adjuvant therapy to scaling and root planing (SRP) on the clinical and radiographic parameters and prostaglandin E-2 (PGE(2)) levels in aggressive periodontitis. Methods: Subjects were randomly allocated to test or control treatment (n = 10 in each group) and submitted to SRP and treatment with etoricoxib, 120 mg/day, or placebo for 7 days. Probing depth, clinical attachment level (CAL), gingival recession, visible plaque index, bleeding on probing, linear distance (LD) from the cemento-enamel junction to the alveolar crest, and analysis of the gray levels were recorded before and 1 month after the therapies. The prostaglandin E-2 (PGE(2)) level in the gingival crevicular fluid (GCF) was measured by radioimmunoassay at the beginning of the study and 7 and 30 days after treatment. Results: No significant difference in the clinical parameters was observed between the groups at the end of the experimental period, although both groups presented significant improvement in all variables examined. There was a decrease in CAL from 5.54 +/- 0.47 mm to 3.59 +/- 0.53 mm in the test group and from 5.92 +/- 1.10 mmto 3.69 +/- 0.80 mm in the control group. A significant reduction in PGE(2) was found after 7 days of treatment. LD differed between the groups. Conclusion: Etoricoxib did not promote additional improvement in the clinical parameters; however, it produced an initial reduction in the PGE(2) levels in the GCF, which could be related to the discrete improvement in the bone condition.

Efficacy and tolerance of metronidazole and miconazole nitrate in treatment of vaginitis

Objective: To evaluate the efficacy and tolerability of a vaginal pessary containing 750 mg of metronidazole and 200 mg of miconazole nitrate used daily for 7 days in the treatment of vaginitis. Methods: Ninety-two women with vaginitis participated in this phase 3 study using one vaginal pessary daily for 7 days. Gynecological and microbiological evaluations were carried out prior to and following treatment. Results: Reductions occurred in symptoms and signs of vaginitis. Clinical cure rate was 87.7%, while the cure rates according to microscopy and Candida albicans culture were 81.8% and 73.9%, respectively. The cure rate for bacterial vaginosis was 75% and culture of Gardnerella vaginalis turned negative in 63.6% of cases following treatment. The medication was well tolerated. Conclusion: Use of a combination of 750 mg of metronidazole and 200 mg of miconazole in a single daily application was found to be effective in the treatment of the most common causes of vaginitis.

Cannabidiol for the treatment of psychosis in Parkinson`s disease

The management of psychosis in Parkinson`s disease (PD) has been considered a great challenge for clinicians and there is a need for new pharmacological intervention. Previously an antipsychotic and neuroprotective effect of Cannabidiol (CBD) has been suggested. Therefore, the aim of the present study was to directly evaluate for the first time, the efficacy, tolerability and safety of CBD on PD patients with psychotic symptoms. This was an open-label pilot study. Six consecutive outpatients (four men and two women) with the diagnosis of PD and who had psychosis for at least 3 months were selected for the study. All patients received CBD in flexible dose (started with an oral dose of 150 mg/day) for 4 weeks, in addition to their usual therapy. The psychotic symptoms evaluated by the Brief Psychiatric Rating Scale and the Parkinson Psychosis Questionnaire showed a significant decrease under CBD treatment. CBD did not worsen the motor function and decreased the total scores of the Unified Parkinson`s Disease Rating Scale. No adverse effect was observed during the treatment. These preliminary data suggest that CBD may be effective, safe and well tolerated for the treatment of the psychosis in PD.

Intravitreal triamcinolone versus bevacizumab for treatment of refractory diabetic macular oedema (IBEME study)

Background/aims: The aim of this study was to compare the morphological and visual acuity outcomes associated with a single intravitreal injection of triamcinolone acetonide versus bevacizumab for the treatment of refractory diffuse diabetic macular oedema. Methods: Twenty-eight patients were randomly assigned to receive a single intravitreal injection of either 4 mg/0.1 ml triamcinolone acetonide or 1.5 mg/0.06 ml bevacizumab. Comprehensive ophthalmic evaluation was performed at baseline and at weeks 1, 4, 8 (+/- 1), 12 (+/- 2) and 24 (+/- 2) after treatment. Main outcome measures included central macular thickness measured with optical coherence tomography (OCT) and best corrected Early Treatment Diabetic Retinopathy Study (ETDRS) visual acuity. Results: Twenty-six patients (26 eyes) completed all study visits (two patients missed two consecutive study visits). Central macular thickness was significantly reduced in the intravitreal triamcinolone group compared with the bevacizumab group at weeks 4, 8, 12 and 24 (p<0.05). Logarithm of the minimum angle of resolution (LogMAR) best-corrected visual acuity was significantly higher at weeks 8 (0.69; similar to 20/100(+1)) and 12 (0.74; 20/100(-2)) in the intravitreal triamcinolone group compared with the bevacizumab group (weeks 8 (0.83; similar to 20/125(-1)) and 12 (0.86; 20/ 160(+2))) (p<0.05). Significant change from baseline in mean intraocular pressure (mmHg) was seen at week 4 (+2.25) only in the intravitreal triamcinolone group (p<0.0001). No patient had observed cataract progression during the study. Conclusions: One single intravitreal injection of triamcinolone may offer certain advantages over bevacizumab in the short-term management of refractory diabetic macular oedema, specifically with regard to changes in central macular thickness. The actual clinical relevance of our preliminary findings, however, remains to be determined in future larger studies.

Is Suppression of Hypothalamic-Pituitary-Adrenal Axis Significant During Clinical Treatment of Phimosis?

Purpose: Corticoids have been an option for phimosis treatment since 1993. However, long-term use or repeated cycles pose a concern regarding drug absorption and consequent systemic effects. The aim of this study was to investigate the effect of topical corticoids used in treating phimosis on the hypothalamus-pituitary-adrenal axis in children. Materials and Methods: A total of 31 children were included in the study. Cortisol secretion was evaluated by the measurement of salivary cortisol in saliva samples collected at 9:00 a.m, before starting treatment and after 8 weeks of topical treatment with 0.05% clobetasol propionate. Salivary cortisol was determined by radioimmunoassay. To confirm that use of clobetasol propionate was not detected by the assay, the presence of cortisol circadian rhythm was checked by an extra saliva sample obtained at 11:00 p.m. from 10 children, and was observed to be maintained in all of them. Results: No significant difference in salivary cortisol levels was observed between samples obtained at 9:00 a.m. before starting treatment and after completing treatment when the entire group was analyzed. However, in 2 children the salivary cortisol levels after treatment were lower than the cutoff value (358 ng/dl) assumed to be suggestive of hypothalamus-pituitary-adrenal axis suppression. Conclusions: Topical clobetasol propionate used twice daily for clinical treatment of phimosis does not affect the hypothalamus-pituitary-adrenal axis in most patients. However, salivary cortisol level should be considered as a laboratory marker in long-term treatment or during repeated cycles to detect possible hypothalamus-pituitary-adrenal axis suppression.

Long-term treatment of familial male-limited precocious puberty (testotoxicosis) with cyproterone acetate or ketoconazole

Background Familial male-limited precocious puberty (FMPP) or testotoxicosis is a rare gonadotrophin-independent form of sexual precocity caused by constitutively activating mutations of the LH receptor. Several clinical therapeutic approaches have been reported for this disorder, but with a paucity of long-term outcome data. Objective To evaluate the long-term treatment of testotoxicosis with cyproterone acetate or ketoconazole. Design A multicentric retrospective clinical study. Patients Ten boys from eight unrelated Brazilian families who carried known LH-receptor activating mutations were treated with 70 mg/m(2) cyproterone acetate (n = 5) or 10 mg/kg ketoconazole (n = 5) for a mean period of 5 and 8 years, respectively. Measurements Chronological and bone ages, bone age/chronological age ratio, target height (TH) range, adult height, basal and GnRH-stimulated gonadotrophin levels and basal testosterone levels were assessed. Results Growth velocity decreased significantly during treatment with cyproterone acetate or ketoconazole when compared to pretreatment value in each group (P < 0.05). Bone age/chronological age ratio decreased significantly after cyproterone acetate or ketoconazole therapy. Basal testosterone levels were significantly lower in patients undergoing ketoconazole compared to cyproterone acetate treatment [0.6 +/- 0.3 nmol/l (42 +/- 21 ng/dl) vs. 5.6 +/- 4.0 nmol/l (392 +/- 280 ng/dl); P < 0.05], as expected. Secondary gonadotrophin-dependent precocious puberty occurred at a similar frequency (40%) in both groups. Five patients have attained adult height and two patients have already reached 90% of their adult height. Two of them achieved their TH range and one patient, for whom TH was not available, had an adult height of 0.3 SDS. Four boys (two in each group) did not attain their TH range. Conclusion Long-term treatment with cyproterone acetate or ketoconazole resulted in similar outcomes without important side-effects in boys with testotoxicosis. However, both therapies showed limited efficacy in attaining normal adult height.

Treatment of Hepatocellular Carcinoma With Liver Transplantation: A Single-Center Experience From Brazil

Introduction. Orthotopic liver transplantation (OLT) is the treatment of choice of hepatocellular carcinoma (HCC) for patients with cirrhosis, mainly those with early HCC. Herein we have present the clinical characteristics and outcomes of cirrhotic patients with HCC who underwent OLT from cadaveric donors in our institution. Methods. From May 2001 to May 2009, we performed 121 OLT including 24 patients (19.8%) with cirrhosis and HCC within the Milan criteria. In 4 cases, HCC was an incidental finding in the explants. Results. The patients` average age was 55 +/- 10 years, including 82% men. Fifty percent of patients were Child class B or C. The average Model for End Stage Liver Disease for Child A, B, and C categories were 11, 15, and 18, respectively. The HCC diagnosis was made by 2 dynamic images in 16 cases; 1 dynamic image plus alphafetoprotein >400 ng/mL in 4; and 4 by histologic confirmation. Twenty patients received a locoregional treatment before OLT: 6 percutaneous ethanol injection, 9 transarterial chemoembolization, 1 transarterial embolization, and 4 a combination of these modalities. The median follow-up after OLT was 19.7 months (range, 1-51). A vascular invasion was observed in the explant of 1 patient, who developed an HCC recurrence and succumbed at 8 months after OLT. Two further patients, without vascular invasion or satellite tumor displayed tumor recurrences at 7 and 3 months after OLT, and death at 2 and 1 month after the diagnosis. The remaining 25 patients have not shown a tumor recurrence. Conclusion. In the present evaluation, OLT patients with early HCC and no vascular invasion showed satisfactory results and good disease-free survival. Strictly following the Milan criteria for liver transplantation in patients with HCC greatly reduces but does not completely avoid, the chances of tumor recurrence.

Treatment of Brain Arteriovenous Malformations by Double Arterial Catheterization with Simultaneous Injection of Onyx: Retrospective Series of 17 Patients

BACKGROUND AND PURPOSE: The use of Onyx in the treatment of intracranial AVMs has increased the cure rate of endovascular embolization compared with the use of liquid adhesive agents. Inadvertent occlusion of the draining veins before the complete exclusion of the nidus constitutes a major risk of bleeding. We report a case series using the technique of double simultaneous arterial catheterization as an approach to achieve the complete, exclusion of the nidus before reaching the venous drainage, through a more controlled hemodynamic filling. MATERIALS AND METHODS: Between April 2008 and November 2009, 17 patients with brain AVMs were treated by the DACT. The mean age of the patients was 32.7 years (range, 6-54 years), with 9 females and 8 males. The clinical onset was characterized by intracranial hemorrhage in 8 patients and by seizures in 7. The size of the AVMs ranged from 13 to 54 mm (average, 26.2 mm). The DACT was always used with the objective of curing the AVM. RESULTS: All 17 patients completed the EVT. The average number of sessions conducted was 1.4 (range, 1-3 sessions), with the average injection amount of 6.9 mL of Onyx (range, 2-25.2 mL). Sixteen AVMs (94.1%) were angiographically cured by embolization. Clinical complications occurred in 2 patients (11.7%); 1 of these was permanent (5.9%). No deaths were registered. CONCLUSIONS: This preliminary series shows that the DACT presents satisfactory results when used with curative intent.

Interchangeability among therapeutics equivalents of lamotrigine in the treatment of refractory epilepsy patients: risks and benefits

Introduction. Epilepsy is a condition characterized by signs and symptoms of neurological disorder. Lamotrigine has been widely used, mainly due to their greater tolerability and lower rate of drug interactions with other antiepileptic drugs however the newest antiepileptic drugs have high cost to patient. In Brazil there are three different sort of pharmaceutical equivalents (reference, generic and similar), and the Brazilian health care authorities offers to users the possibility to receive them free of charge. Moreover these pharmaceutical equivalents can change during the treatment of epilepsy because this authorities buy the cheapest by public tender two or three times a year. Aim. To evaluate the clinical and laboratory findings related to the most frequently used therapeutic equivalents of lamotrigine (reference drugs and similar products). Patients and methods. Two similar formulations (A and B) and one reference (C) were tested in nine epileptic refractory patients. The study was divided into three periods of 42 days, one for each formulation, and medical data about the frequency of seizures, the occurrence of side effects and measurement of plasma concentrations of lamotrigine were collected. Results. The average number of seizures/week and plasma concentration of lamotrigine for formulations A, B and C were not statistically significant differences. Three patients during the use of the formulation C presented mild and transitory side effects. Conclusion. Similar or reference drugs showed satisfactory results, however the interchangeability among the formulations raise the difficulty for the management of seizures in refractory epilepsy.

Clinical study of cryosurgery efficacy in the treatment of skin and subcutaneous tumors in dogs and cats

Objective-To evaluate the efficacy of cryosurgery for treatment of skin and subcutaneous tumors in dogs and cats. Study Design-Prospective study. Animals-Dogs (n = 20), cats (10). Methods-Cutaneous or subcutaneous tumors were treated by liquid nitrogen cryosurgical spray (1 cm from target tissue at 90 degrees until a 5-mm halo of frozen tissue was achieved) for 15-60 seconds. Malignant lesions had 3 freeze-thaw cycles benign tumors, 2 cycles. The second or third freeze cycle was performed after complete thaw of the preceding freeze. Wounds healed by second intention. Follow-up was weekly for 1 month and then twice monthly until wounds healed, and final outcome was determined by telephone interview of owners. Results-Tumor size ranged from 0.3 to 11 cm, diameter with 28 (60%) being 0.3-1 cm; 8 (17%) 1.1-3cm, and 11 (23%) >3.4cm. Complications included edema, erythema and for extremity lesions, pain and lameness. Treated lesions (n = 47) had an overall remission of 98% (mean follow-up.. 345 +/- 172.02 days [range, 150-750 days]). One malignant peripheral nerve sheath tumor recurred 7 months after cryosurgical treatment. Conclusion-Cryo surgery is an efficient method for treatment of skin and subcutaneous tumors in dogs and cats. Clinical Relevance-Cryosurgical ablation is an effective means of treating small cutaneous or subcutaneous tumors in dogs and cats, especially in older animals where wound closure or cosmetic outcome might limit surgical excision alone.

E-mail: alegtd@yahoo.com.br The goal of this study was to evaluate the in vitro sensitivity to enrofloxacin of bacteria isolated from the oral cavity of cats with chronic gingivitis. Twenty five cats male and famale with variable degrees of gingivitis were included in this study. The samples were colected by culturette swabs and submitted to bacterial culture and sensitivity. The results showed that 91% of the bacteria isolated from the culture were sensitive to enrofloxacin, demonstrating that this antibiotic is a good option in the clinical treatment or post-operative treatment of feline chronic gingivitis.

A randomized controlled trial of homeopathic treatment of weaned piglets in a commercial swine herd

Aim: To evaluate the zootechnic performance and occurrence of diarrhea in piglets in the week post-weaning comparing supplementation with sucrose saline which contained or did not contain added homeopathic medicine. Method. Animals were randomly divided into three groups of 24 piglets each. The control group did not receive any treatment. Another group received sucrose saline, and the third group received sucrose saline with homeopathic medicine added, in the period of zero to seven days post-weaning. The homeopathic treatment consisted of Echinacea angustifolia, Avena sativa, Ignatia amara, Calcarea carbonica, all 6cH. Piglets were weighed daily for weight gain or loss, and observed for diarrhea and feed intake. Results: Animals receiving sucrose saline alone and sucrose saline with homeopathy had less weight loss than control (p = 0.017, p = 0.0001 respectively). There was no statistical difference in relation to overall incidence of diarrhea or food consumption. These data suggest that the supplementation with sucrose saline with added homeopathic medicine in the first seven days post-weaning may be an useful option to reduce weight loss in weaned piglets. Homeopathy (2008) 97, 202-205.

Pre-treatment of cattle sperm and/or oocyte with antibody to lipocalin type prostaglandin D synthase inhibits in vitro fertilization and increases sperm-oocyte binding

The present study was conducted to determine the affect of pre-treating of oocytes and/or sperm with a rabbit polyclonal antibody against recombinant cattle lipocalin type prostaglandin D synthase (alpha L-PGDS) on in vitro sperm-oocyte binding and fertilization. In vitro matured cattle oocytes were incubated (39 degrees C, 5% CO2 in air) for I It in the following treatments either 500 mu L of fertilization medium (FM) or FM with alpha L-PGDS (1:2000). Frozen-thawed spermatozoa were washed by a 45/90% layered Percoll gradient centrifugation and incubated for I h either FM or FM with a L-PGDS. This study utilized five different treatments: (1) no antibody (control); (2) a rabbit IgG against a non-bovine antigen, bacterial histidase (alpha-hist); (3) a L-PGDS at fertilization time (with fertilization medium); (4) alpha L-PGDS-treated oocytes; or (5) a L-PGDS-treated sperm. Pre-treated oocytes were incubated with 10 X 10(4) washed spermatozoa per 25 oocytes. Oocytes used to assess sperm binding were stained with Hoescht 33342, and the number of sperm bound per zonae pellucidae counted. The remaining oocytes were fixed in acid alcohol, stained with 1% acetate-orcein and observed to determine the presence of pronuclei. More sperm bound to the zonae pellucidae when oocytes and/or sperm were pre-treated with alpha. L-PGDS: (1) 26.4 +/- 3.0; (2) 25.6 +/- 3.0; (3) 59.7 +/- 3.0; (4) 56.4 +/- 3.0; and (5) 57.1 +/- 3.0. Addition of alpha L-PGDS with sperm, oocytes, or both, decreased fertilization (P < 0.05) compared with the control: (1) 89.2 +/- 2.0%; (2) 87.5 +/- 2.0%; (3) 19.4 +/- 2.0%; (4) 27.2 +/- 3.1%; and (5) 14.1 +/- 3.4%. The alpha L-PGDS reacts with both oocytes and spermatozoa, resulting in increases of in vitro sperm-oocyte binding and inhibition of fertilization. These observations suggest that L-PGDS may have a role in cattle fertilization. (c) 2007 Elsevier B.V. All rights reserved.

GLOBAL POSTURAL REEDUCATION AND STATIC STRETCHING EXERCISES IN THE TREATMENT OF MYOGENIC TEMPOROMANDIBULAR DISORDERS: A RANDOMIZED STUDY

Objective: The purpose of this study was to compare 2 different interventions, global postural reeducation (GPR) and static stretching exercises (SS), in the treatment of women with temporomandibular disorders (TMDs). Methods: A total of 28 subjects with TMDs were randomized into 2 treatment groups: GPR, where therapy involved muscle global chain stretching, or SS, with conventional static stretching; but only 24 completed the study. Eight treatment sessions lasting 40 minutes each (weekly) were performed. Assessments were conducted at baseline, immediately after treatment end, and 2 months later. Measurements included pain intensity at the temporomandibular joint, headache, cervicalgia, teeth clenching, ear symptoms, restricted sleep, and difficulties for mastication, using a visual analogue scale. In addition, electromyographic activity and pain thresholds were measured at the masseter, anterior temporalis, stemocleidomastoid, and upper trapezius muscles. Two-way analysis of variance with Tukey post hoc test was used for between-group comparisons. Significance level was .05. Results: Comparing the pain assessments using the visual analogue scale, no significant differences were seen with the exception of severity of headaches at treatment end (GPR, 3.92 +/- 2.98 cm; SS, 1.64 +/- 1.66 cm; P < .024). In addition, no significant differences were seen for pain thresholds and for electromyographic activity (P > .05). Conclusions: For the subjects in this study, both GPR and SS were similarly effective for the treatment of TMDs with muscular component. They equally reduced pain intensity, increased pain thresholds, and decreased electromyographic activity. (J Manipulative Physiol Ther 2010;33:500-507)
