Musculoskeletal Dysfunction and Pain in Adults with Asthma

Background. The mechanical alterations related to the overload of respiratory muscles observed in adults with persistent asthma might lead to the development of chronic alterations in posture, musculoskeletal dysfunction and pain; however, these changes remain poorly understood. Objective. This study aimed to assess postural alignment, muscle shortening and chronic pain in adults with persistent asthma. Methods. This cross-sectional and controlled study enrolled 30 patients with mild (n = 17) and severe ( n = 13) persistent asthma. Fifteen non-asthmatic volunteers were also assessed. Asthma was classified by the Global Initiative for Asthma (GINA) guidelines. Postural alignment and muscle shortening were evaluated by head and shoulder positions, chest wall mobility, and posterior ( trunk and lower limb) muscle flexibility. In addition, the measures used were previously tested for their reproducibility. Pain complaints were also assessed. Results. In comparison with non-asthmatic subjects, patients with mild or severe persistent asthma held their head and shoulders more forward and had lower chest wall expansion, decreased shoulder internal rotation, and decreased thoracic spine flexibility. Chronic lower thoracic, cervical, and shoulder pain was significantly increased in patients with mild or severe asthma compared with non-asthmatic subjects (p < 0.05). Conclusion. Adults with persistent asthma have musculoskeletal dysfunction and chronic pain that is independent of the severity of their disease but that might be related to their age at the onset of disease symptoms.

Seven-year trend analysis of nosocomial candidemia and antifungal (fluconazole and caspofungin) use in Intensive Care Units at a Brazilian University Hospital

Candidemia is associated with high morbidity and mortality resulting in significant increases in the length of patients` hospitalization and in healthcare costs. Critically ill patients are at particular risk for candidemia because of their debilitated condition and frequent need for invasive procedures. The aim of this study was to characterize the incidence and epidemiology of candidemia over a seven-year period in intensive care units (ICUs) and the use of fluconazole and caspofungin in a large university-affiliated hospital. All cases of candidemia were identified by surveillance, using the Centers for Diseases Control and Prevention criteria. Demographic variables, use of antifungal (fluconazole and caspofungin) and patient outcomes were evaluated. The 2 test for linear trend was employed to evaluate the distribution of Candida spp. and the use of fluconazole and caspofungin by defined daily dose (DDD) per 1,000 patients-days during the study period. One hundred and eight episodes of candidemia were identified. The overall incidence of candidemia (P=0.20) and incidence of non-Candida albicans Candida infections (P=0.32) remained stable over the study period and ranged from 0.3-0.9 episodes per 1,000 catheter-days and 0.39-0.83 episodes per 1,000 patients-days. However, the use of fluconazole and caspofungin increased significantly (P0.001). While there were no reports of the use of fluconazole for prophylaxis in 1999, its use for this purpose increased from 3% in 2000 to 7.0% (P=0.07) in 2006. C. albicans was the most frequent specie isolated and burns and cancer were the most frequent underlying conditions. The overall mortality was 76%. There was no difference between C. albicans and non-C. albicans Candida infections when the crude and 14-day mortality rates were compared. Our data demonstrated that C. albicans is still the most frequent species causing candidemia in our intensive care units. Our rates of candidemia are lower than those reported from the region and similar to American and European hospitals. Although the incidence of blood stream infections (BSI) and candidemia remained stable, the use of fluconazole and caspofungin increased significantly over the years included in this study but had no impact on the incidence of infections caused by non-C. albicans Candida species.

Microangiopathy of the inner ear, deafness, and cochlear implantation in a patient with Susac syndrome

Conclusion: The cochlear implant was beneficial as an attempt to restore hearing and improve communication abilities in this patient with profound sensorineural hearing loss secondary to Susac syndrome. Objective: To report the audiological outcomes of cochlear implantation (CI) in a young woman with Susac syndrome after a 6-month follow-up period. Susac syndrome is a rare disorder. It is clinically characterized by a typical triad of sensorineural deafness, encephalopathy, and visual defect, due to microangiopathy involving the brain, inner ear, and retina. Methods: This was a retrospective review of a case at a tertiary referral center. After diagnosis, the patient was evaluated by a multidisciplinary team and received a cochlear implant in her right ear. Results: The patient achieved 100% open-set sentence recognition in noise conditions and 92% monosyllable and 68% medial consonant recognition in quiet conditions after 6 months of implant use. She reported the use of the telephone 3 months after activation.

Two-Year Outcome of Partial Lacrimal Punctal Occlusion in the Management of Dry Eye Related to Sjogren Syndrome

Purpose: To analyze the influence of thermal partial punctal occlusion on the ocular surface of dry eye related to Sjogren syndrome. Material and Methods: Thirty-seven eyes of 19 patients (3 male and 16 female; 49.11 +/- 14.33 years old) with keratoconjunctivitis sicca were enrolled in this study. Superior and inferior partial occlusion were performed in both eyes under topical anesthesia using thermal cautery with a sterile tip to obtain lacrimal punctum smaller than 0.5 mm. Schirmer I, break-up-time, diameter of lacrimal puncta, corneal fluorescein, and rose Bengal staining scores were analyzed before and after 24 weeks and after 24 months of the procedure. All measurements were performed under controlled climate. Results: The average lacrimal punctum diameter before the procedure was 0.65 +/- 0.134 mm. All lacrimal puncta were successfully reduced to less than 0.5 mm after 4 weeks of the procedure. The average Schirmer I test values improved statistically after 24 weeks and maintained stable after 24 months. Average break-up-time, rose Bengal, and fluorescein staining score values improved statistically after 24 weeks and improved even more after 24 months. Average Schirmer I test, break-up-time, rose Bengal, and fluorescein staining scores showed significant improvement (p < 0.0001) after 24 months of partial thermal punctal occlusion. Conclusion: Our study showed that reducing the punctum diameter to 0.5 mm can improve vital staining scores, break-up-time, and Schirmer I test in dry eye related to Sjogren syndrome.

The efficacy of functional endoscopic sinus surgery in the evolution of fever of unknown origin in ICU patients

Conclusion: Functional endoscopic sinus surgery (FESS) was found to be effective in treating fever of unknown origin (FUO) in intensive care unit (ICU) patients with rhinosinusitis, with 62% of patients showing improvement within 5 days of the procedure. Objective: To correlate improvement in FUO with FESS drainage of the paranasal sinuses. Methods: Fifty patients that developed FUO during ICU stay, with CT findings suggestive of rhinosinusitis, and showed no improvement in fever after clinical treatment underwent FESS for drainage of the paranasal sinuses and were evaluated for postoperative improvement of fever. Results: The study sample consisted of 50 patients (74% of whom were male, mean age 48.1 years). The most frequent diagnoses at ICU admission were tetanus, pulmonary disease, and cardiovascular disease. In all, 68% of patients underwent nasogastric or enteral intubation. CT scanning most commonly showed involvement of the sphenoid sinus. In 54% of cases, sinusitis was bilateral and extended throughout the maxillary, ethmoidal, and sphenoidal sinuses. Sinusectomy was performed in all patients, and pathological secretion in the paranasal sinuses was seen in 52% of patients during surgery. Gram-negative bacteria were the most commonly isolated organisms, followed by Gram-positive bacteria and fungi. Improvement of fever was found in 82% of patients after FESS; 38% of these improved within the first 48 h post-procedure, and the remaining 62% within the first 5 postoperative days.

Acupuncture-ameliorated menopausal symptoms: single-blind, placebo-controlled, randomized trial

Objectives To evaluate the effects of acupuncture and sham-acupuncture on women with menopausal symptoms as reflected in the intensity of their hot flushes and the Kupperman Menopausal Index (KMI). Method This was a randomized, single-blind, placebo-controlled, cross-over trial with 81 patients assigned to two groups: Group 1 received 12 months of acupuncture, then 6 months of sham-acupuncture treatment (n = 56) and Group 2 received 6 months of sham-acupuncture, then 12 months of acupuncture treatment (n = 25). The needles were inserted in a harmonic craniocaudal manner at a depth of about 2 cm, and each session lasted approximately 40 min. The efficacy of acupuncture in ameliorating the climacteric symptoms of patients in postmenopause was determined through the KMI and the intensity of hot flushes. The analysis of variance method for two factors and repeated measures was applied. Results The baseline values of the women in both groups were similar for the KMI score and number of hot flushes. At the end of 6 months, the values for the KMI and hot flushes for the women in Group 1 were lower than those of the women in Group 2 (p < 0.05). After 12 months, the KMI and hot flush data were similar in both groups. After 18 months, the values of the KMI and hot flushes for the women in Group 2 for were lower than those of the women in Group 1 (p < 0.05). Conclusion Acupuncture treatment for relieving menopausal symptoms may be effective for decreasing hot flushes and the KMI score in postmenopausal women.

Dyslipidemia in women with polycystic ovary syndrome: incidence, pattern and predictors

One hundred forty-two women with polycystic ovary syndrome (PCOS) with an average body mass index (BMI) of 29.1 kg/m(2) and average age of 25.12 years were studied. By BMI, 30.2% were normal, 38.0% were overweight and 31.6% were obese. Thirty-one eumenorrheic women matched for BMI and age, with no evidence of hyperandrogenism, were recruited as controls. The incidence of dyslipidemia in the PCOS group was twice that of the Control group (76.1% versus 32.25%). The most frequent abnormalities were low high-density lipoprotein cholesterol (HDL-C; 57.6%) and high triglyceride (TG) (28.3%). HDL-C was significantly lower in all subgroups of women with PCOS when compared to the subgroups of normal women. No significant differences were seen in the total cholesterol (p = 0.307), low-density lipoprotein cholesterol (LDL-C; p = 0.283) and TGs (p = 0.113) levels among the subgroups. An independent effect on HDL-C was detected for glucose (p = 0.004) and fasting insulin (p = 0.01); on TG for age (p = 0.003) and homeostatic model assessment insulin resistance (p = 0.03) and on total cholesterol and LDL-C for age (p = 0.02 and p = 0.033, respectively). In conclusion, dyslipidemia is common in women with PCOS, mainly due to low HDL-C levels. BMI has a significant impact on this abnormality.

Influence of the CYP17 polymorphism on vasomotor symptoms in postmenopausal women: a pilot study

Objective To evaluate the influence of CYP17 polymorphism on menopausal symptoms after estrogen treatment. Methods A total of 130 women were recruited, but only 100 of these were selected according to inclusion and exclusion criteria; they were treated with 0.3 mg/day conjugated equine estrogens. One year later, the study was completed by 71 women. The analysis of the Kupperman menopausal index symptoms was made with information provided by the patients on daily diary cards. Blood samples were analyzed and the women were divided into two groups based on the CYP17, 5`-untranslated region: group A (wild-type homozygote and heterozygote) and group B (mutated homozygote). Results The values for the Kupperman menopausal index were similar in both groups at baseline. The symptoms in both groups decreased after 1 year of treatment when compared to those at baseline. The improvement rate was approximately 27.09% and 32.18%, in groups A and B, respectively. The levels of estrogen after treatment were higher in both groups in comparison with the baseline values. The testosterone level rose in group B with the 1-year treatment (0.48 +/- 0.16 ng/ml), reaching a higher level than the level in group A after treatment. The sex hormone binding globulin (SHBG) level showed a significant increase after the 1-year treatment in group B, surpassing both the baseline and the after-treatment values in group A (p < 0.01). Conclusion Our data suggest that the CYP17 polymorphism did not influence the action of estrogen on menopause symptoms during the 1-year treatment. The extra production of estrogen and androgen may have been countered by the elevation of SHBG levels.

Protein profile of the luteal phase endometrium by tissue microarray assessment

To investigate the luteal phase endometrial expression of leukemia inhibitor factor (LIF), insulin-like growth factor 1 (IGF-1), progesterone receptor (PR), claudin 4 (CLDN4), vascular-endothelial growth factor receptor 3 (VEGFR-3), bone morphogenetic protein 4 (BMP-4) and citokeratin 7 (CK-7), we obtained luteal phase endometrial samples from 52 women. Samples were dated and integrated using a tissue microarray (TMA). Samples were immunostained for LIF, IGF-1, PR, CLDN4, VEGFR-3, BMP-4 and CK-7. Frequencies of positive expressions at the early, mid and late luteal phases were compared by two proportions test. Concomitant expression of these proteins was assessed with Chi-square or Fischer`s test. The frequency of LIF was positively correlated to the frequency of IGF-1 (r = 0.99; p < 0.05) and PR (r = 0.99; p < 0.05), and the correlation between IGF-1 and PR tended to be significant (r = 0.98; p < 0.1). The expression of PR was associated with the absence of CLDN4 (p < 0.001). Thus, expression of LIF, IGF-1 and PR are correlated during the luteal phase, and immunohistochemistry for these proteins might be used to assist in the assessment of endometrial maturation. In addition, the expression of CLDN4 and PR was not concomitant, warranting further investigation on the relationship of their endometrial expression.

CYP17 polymorphism and hot flushes in postmenopausal women

Objective To investigate the association between the CYP17 alpha gene polymorphism and hot flushes in postmenopausal women. Methods Ninety-three non-hysterectomized, postmenopausal women were enrolled in this study. Vasomotor symptoms were assessed at the baseline visit and based on information provided by each participant. The genotypic polymorphism of CYP17 alpha gene was analyzed by PCR-RFLP assay using genomic DNA isolated from peripheral blood lymphocytes. Results Thirty-six women reported hot flushes of mild intensity, 25 reported hot flushes of moderate intensity and 32 of severe intensity. There was no significant difference between the severity of hot flushes and the CYP17 genotype or allele frequencies, 0.58 and 0.67 respectively. No association was found between hot flush severity and the CYP17 allele (odds ratio = 1.17, p = 0.61). Conclusion The results of this study suggest that the CYP17 MspAI polymorphism was not significantly associated with an increased risk of reporting hot flushes. At the World Congress on Menopause in Madrid, May 2008, Dr Massad-Costa was awarded the Robert Greenblatt Prize for Basic Science for the study reported in this paper.

The effects of cinnarizine on menopausal symptoms in women

Objective To evaluate the effectiveness and safety of cinnarizine in the treatment of menopausal symptoms. Design A total of 100 climacteric and symptomatic women participated in a double-blind, placebo-controlled study. They were divided into two groups of the same size: Gcin, intake of 25 mg of cinnarizine every 12 h for 6 months (n = 50); and Gpla, placebo intake every 12 hours for 6 months (n = 50). Menopausal symptoms were evaluated according to the Kupperman menopausal index on the first visit and at 6 months of treatment. A total of 62 women completed the study: 27 from the Gcin group and 35 from the Gpla group. Results Based on the Kupperman menopausal index, there were no statistically significant differences between the two groups before and after the treatment. Conclusion Our data suggest cinnarizine is not effective on menopausal symptoms because it had no more efficacy than placebo.

Evaluation of melatonin on the precocious puberty: a pilot study

Objective. To evaluate the effect of 6-sulphatoxymelatonin on the sleep quality of girls with precocious puberty. Study design. Ninety-nine girls were divided into three groups: GI, precocious puberty; GII, normal prepubescent; GIII, normal puberty. Questionnaires containing demographic and clinical data were applied. Blood was collected for hormonal evaluation for 6-sulphatoxymelatonin. The modified Rush Sleep Diary was used. Results. The levels of 6-sulphatoxymelatonin were highest in the group without pubertal development (75.23 +/- 10.84 ng/ml), second highest in the group with normal puberty (45.66 +/- 3.87 ng/ml, p < 0.001) and lowest in the group with true precocious puberty (37.04 +/- 5.47 ng/ml). The amount of day sleep was greater in the group without pubertal development compared to other groups. Conclusion. Despite the sleep data, melatonin may be involved in the precocious puberty process.

Platelet GSK3B activity in patients with late-life depression: Marker of depressive episode severity and cognitive impairment?

Objective. Increased GSK3B activity has been reported as a state marker of major affective episodes in patients with depression and bipolar disorder. No study so far has addressed GSK3B activity in late-life depression. The aims of the present study were to determine GSK3B activity in platelets of elderly patients with major depression, and the association between GSK3B activity and the severity of depressive symptoms and cognitive impairment. Methods. Forty drug-free elderly patients with major depressive episode were compared to healthy older adults (n == 13). Severity of the depressive episode and current cognitive state were determined by the Hamilton Depression Scale (HAM-D) and the Cambridge Cognitive Test (CAMCOG), respectively. Total- and ser-9-phosphorylated GSK3B (tGSK3B and pGSK3B) were determined in platelets by enzyme immunometric assays (EIA). GSK3B activity was indirectly inferred by the GSK3B ratio (i.e. pGSK3B/tGSK3B). Results. Elderly depressed patients had significantly lower pGSK3B levels (P == 0.03) and GSK3B ratio (P == 0.03), indicating higher GSK3B activity. Higher GSK3B activity were observed in patients with severe depressive episode (HAM-D scores > 22, P == 0.03) and with cognitive impairment (CAMCOG scores < 86, P == 0.01). Conclusion. The present findings provide additional evidence of the involvement of GSK3B in the pathophysiology of late-life major depression. Higher GSK3B activity may be more relevant in those patients with more severe depressive symptoms and cognitive impairment.

Lateral ventricle differences between first-episode schizophrenia and first-episode psychotic bipolar disorder: A population-based morphometric MRI study

Objectives. The extent to which psychotic disorders fall into distinct diagnostic categories or can be regarded as lying on a single continuum is controversial. We compared lateral ventricle volumes between a large sample of patients with first-episode schizophrenia or bipolar disorder and a healthy control group from the same neighbourhood. Methods. Population-based MRI study with 88 first-episode psychosis (FEP) patients, grouped into those with schizophrenia/schizophreniform disorder (N = 62), bipolar disorder (N = 26) and 94 controls. Results. Right and left lateral ventricular and right temporal horn volumes were larger in FEP subjects than controls. Within the FEP sample, post-hoc tests revealed larger left lateral ventricles and larger right and left temporal horns in schizophrenia subjects relative to controls, while there was no difference between patients with bipolar disorder and controls. None of the findings was attributable to effects of antipsychotics. Conclusions. This large-sample population-based MRI study showed that neuroanatomical abnormalities in subjects with schizophrenia relative to controls from the same neighbourhood are evident at the first episode of illness, but are not detectable in bipolar disorder patients. These data are consistent with a model of psychosis in which early brain insults of neurodevelopmental origin are more relevant to schizophrenia than to bipolar disorder.
