The impact of asymptomatic vertebral fractures on quality of life in older community-dwelling women: the Sao Paulo Ageing & Health Study

OBJECTIVES: The aim of this study was to investigate the impact of asymptomatic vertebral fractures on the quality of life in older women as part of the Sao Paulo Ageing & Health Study. METHODS: This study was a cross-sectional study with a random sample of 180 women 65 years of age or older with or without vertebral fractures. The Quality of Life Questionnaire of the European Foundation for Osteoporosis was administered to all subjects. Anthropometric data were obtained by physical examination, and the body mass index was calculated. Lateral thoracic and lumbar spine X-ray scans were obtained to identify asymptomatic vertebral fractures using a semi-quantitative method. RESULTS: Women with asymptomatic vertebral fractures had lower total scores [61.4(15.3) vs. 67.1(14.2), p = 0.03] and worse physical function domain scores [69.5(20.1) vs. 77.3(17.1), p = 0.02] for the Quality of Life Questionnaire of the European Foundation for Osteoporosis compared with women without fractures. The total score of this questionnaire was also worse in women classified as obese than in women classified as overweight or normal. High physical activity was related to a better total score for this questionnaire (p = 0.01). Likewise, lower physical function scores were observed in women with higher body mass index values (p < 0.05) and lower physical activity levels (p < 0.05). Generalized linear models with gamma distributions and logarithmic link functions, adjusted for age, showed that lower total scores and physical function domain scores for the Quality of Life Questionnaire of the European Foundation for Osteoporosis were related to a high body mass index, lower physical activity, and the presence of vertebral fractures (p < 0.05). CONCLUSION: Vertebral fractures are associated with decreased quality of life mainly physical functioning in older community-dwelling women regardless of age, body mass index, and physical activity. Therefore, the results highlight the importance of preventing and controlling asymptomatic vertebral fractures to reduce their impact on quality of life among older women.

Somatotroph pituitary adenoma with acromegaly and autosomal dominant polycystic kidney disease: SSTR5 polymorphism and PKD1 mutation

A 39-year-old woman with autosomal dominant polycystic kidney disease (ADPKD) presented with acromegaly and a pituitary macroadenoma. There was a family history of this renal disorder. She had undergone surgery for pituitary adenoma 6 years prior. Physical examination disclosed bitemporal hemianopsia and elevation of both basal growth hormone (GH) 106 ng/mL (normal 0-5) and insulin-like growth factor (IGF-1) 811 ng/mL (normal 48-255) blood levels. A magnetic resonance imaging scan disclosed a 3.0 cm sellar and suprasellar mass with both optic chiasm compression and left cavernous sinus invasion. Pathologic, cytogenetic, molecular and in silico analysis was undertaken. Histologic, immunohistochemical and ultrastructural studies of the lesion disclosed a sparsely granulated somatotroph adenoma. Standard chromosome analysis on the blood sample showed no abnormality. Sequence analysis of the coding regions of PKD1 and PKD2 employing DNA from both peripheral leukocytes and the tumor revealed the most common PKD1 mutation, 5014_5015delAG. Analysis of the entire SSTR5 gene disclosed the variant c.142C > A (p.L48M, rs4988483) in the heterozygous state in both blood and tumor, while no pathogenic mutations were noted in the MEN1, AIP, p27Kip1 and SSTR2 genes. To our knowledge, this is the fourth reported case of a GH-producing pituitary adenoma associated with ADPKD, but the first subjected to extensive morphological, ultrastructural, cytogenetic and molecular studies. The physical proximity of the PKD1 and SSTR5 genes on chromosome 16 suggests a causal relationship between ADPKD and somatotroph adenoma.

Hand-carried ultrasound performed at bedside in cardiology inpatient setting – a comparative study with comprehensive echocardiography

Abstract Background Hand-carried ultrasound (HCU) devices have been demonstrated to improve the diagnosis of cardiac diseases over physical examination, and have the potential to broaden the versatility in ultrasound application. The role of these devices in the assessment of hospitalized patients is not completely established. In this study we sought to perform a direct comparison between bedside evaluation using HCU and comprehensive echocardiography (CE), in cardiology inpatient setting. Methods We studied 44 consecutive patients (mean age 54 ± 18 years, 25 men) who underwent bedside echocardiography using HCU and CE. HCU was performed by a cardiologist with level-2 training in the performance and interpretation of echocardiography, using two-dimensional imaging, color Doppler, and simple calliper measurements. CE was performed by an experienced echocardiographer (level-3 training) and considered as the gold standard. Results There were no significant differences in cardiac chamber dimensions and left ventricular ejection fraction determined by the two techniques. The agreement between HCU and CE for the detection of segmental wall motion abnormalities was 83% (Kappa = 0.58). There was good agreement for detecting significant mitral valve regurgitation (Kappa = 0.85), aortic regurgitation (kappa = 0.89), and tricuspid regurgitation (Kappa = 0.74). A complete evaluation of patients with stenotic and prosthetic dysfunctional valves, as well as pulmonary hypertension, was not possible using HCU due to its technical limitations in determining hemodynamic parameters. Conclusion Bedside evaluation using HCU is helpful for assessing cardiac chamber dimensions, left ventricular global and segmental function, and significant valvular regurgitation. However, it has limitations regarding hemodynamic assessment, an important issue in the cardiology inpatient setting.

Observational study on efficacy of negative expiratory pressure test proposed as screening for obstructive sleep apnea syndrome among commercial interstate bus drivers - protocol study

Abstract Background Obstructive sleep apnea (OSA) is a respiratory disease characterized by the collapse of the extrathoracic airway and has important social implications related to accidents and cardiovascular risk. The main objective of the present study was to investigate whether the drop in expiratory flow and the volume expired in 0.2 s during the application of negative expiratory pressure (NEP) are associated with the presence and severity of OSA in a population of professional interstate bus drivers who travel medium and long distances. Methods/Design An observational, analytic study will be carried out involving adult male subjects of an interstate bus company. Those who agree to participate will undergo a detailed patient history, physical examination involving determination of blood pressure, anthropometric data, circumference measurements (hips, waist and neck), tonsils and Mallampati index. Moreover, specific questionnaires addressing sleep apnea and excessive daytime sleepiness will be administered. Data acquisition will be completely anonymous. Following the medical examination, the participants will perform a spirometry, NEP test and standard overnight polysomnography. The NEP test is performed through the administration of negative pressure at the mouth during expiration. This is a practical test performed while awake and requires little cooperation from the subject. In the absence of expiratory flow limitation, the increase in the pressure gradient between the alveoli and open upper airway caused by NEP results in an increase in expiratory flow. Discussion Despite the abundance of scientific evidence, OSA is still underdiagnosed in the general population. In addition, diagnostic procedures are expensive, and predictive criteria are still unsatisfactory. Because increased upper airway collapsibility is one of the main determinants of OSA, the response to the application of NEP could be a predictor of this disorder. With the enrollment of this study protocol, the expectation is to encounter predictive NEP values for different degrees of OSA in order to contribute toward an early diagnosis of this condition and reduce its impact and complications among commercial interstate bus drivers.

Clinical judgment to estimate pretest probability in the diagnosis of Cushing's syndrome under a Bayesian perspective

OBJECTIVE: To estimate the pretest probability of Cushing's syndrome (CS) diagnosis by a Bayesian approach using intuitive clinical judgment. MATERIALS AND METHODS: Physicians were requested, in seven endocrinology meetings, to answer three questions: "Based on your personal expertise, after obtaining clinical history and physical examination, without using laboratorial tests, what is your probability of diagnosing Cushing's Syndrome?"; "For how long have you been practicing Endocrinology?"; and "Where do you work?". A Bayesian beta regression, using the WinBugs software was employed. RESULTS: We obtained 294 questionnaires. The mean pretest probability of CS diagnosis was 51.6% (95%CI: 48.7-54.3). The probability was directly related to experience in endocrinology, but not with the place of work. CONCLUSION: Pretest probability of CS diagnosis was estimated using a Bayesian methodology. Although pretest likelihood can be context-dependent, experience based on years of practice may help the practitioner to diagnosis CS. Arq Bras Endocrinol Metab. 2012;56(9):633-7

Carcinoma de células escamosas em glândula mamária de gata doméstica

Background: In the feline species, 80% to 93% of neoplasias in the mammary gland are malignant, being the majority carcinomas. Among them, there is the mammary squamous cell carcinoma, which amounts to a very rare neoplasm in the domestic cat, with considerable potential for malignancy. This study aimed to report a case of squamous cell mammary carcinoma in the feline species. Case: A female cat, mixed breed, ten years old, presented history of skin lesion. The cat had been spayed two years before, but with previous administration of contraceptives. At the physical examination, it was observed ulcer between the caudal abdominal mammary glands. The occurrence of skin or mammary neoplasia was conceived. The following complementary tests were requested: complete blood count, serum biochemical profi le (renal and hepatic), chest radiographs, abdominal ultrasound, and incisional biopsy of the ulcerated region periphery, followed by classic histopathology. The lesion histopathology was compatible with squamous cell carcinoma of the mammary gland. Due to such a diagnosis, bilateral mastectomy was recommended. The material obtained during the surgical procedure was sent for anatomopathological analysis. Microscopically, surgical margins infi ltration and a regional lymph node were verifi ed. The owner was advised of the need for complementary therapies and medical monitoring of the cat. However, there was no return. It is noteworthy that the animal’s physical and laboratory examinations showed no neoplasia in other regions, being the squamous cell carcinoma of the mammary gland considered primary. Discussion: The malignant mammary neoplasia genesis in feline species, in general, seems to be related to steroid hormones. The ovariectomized females are less likely to develop the disease when compared to intact cats, but there is no protective effect of surgery on those spayed after two years of age regarding the appearance of the neoplasia. Thus, at the time the reported patient was ovariectomized, this effect no longer occurred. The synthetic progestins regularly used to prevent estrus increase by three times the risk of breast carcinomas onset. In humans, there is no clear defi nition of the etiology and pathogenesis of mammary squamous cell carcinoma. However, it has been suggested its association with extreme forms of squamous metaplasia present in pre-existing mammary adenocarcinoma, besides cysts, chronic infl ammations, abscesses and mammary gland adenofi bromas. In a hypothetical way, this etiology could also be related to the feline mammary carcinoma, although, for the case at issue, the exogenous and endogenous hormonal infl uence should not be excluded. It has been reported that mammary squamous cell carcinomas in cats are classifi ed in grades II and III (ie, moderately and poorly differentiated, respectively). Thus, they are considered tumors with more unfavorable prognosis. However, the monitoring of the clinical course, in order to evaluate possible recurrence of the neoplasia and metastases to distant sites, was not possible as the animal under discussion did not return. The squamous cell carcinoma is the most common skin tumor in feline species, despite the primary location in the mammary gland. It is, therefore, important to differentiate squamous cell carcinoma originated in the breast from histological types derived from skin. The description of this special and rare feline mammary carcinoma is important due to its particular characteristics and potential for malignancy.

Usefulness of clinical findings, nerve conduction studies and ultrasonography to predict response to surgical release in idiopathic carpal tunnel syndrome.

[EN] OBJECTIVES: To assess the usefulness of clinical findings, nerve conduction studies and ultrasonography performed by a rheumatologist to predict success in patients with idiopathic carpal tunnel syndrome (CTS) undergoing median nerve release. METHODS: Ninety consecutive patients with CTS (112 wrists) completed a specific CTS questionnaire and underwent physical examination and nerve conduction studies. Ultrasound examination was performed by a rheumatologist who was blind to any patient's data. Outcome variables were improvement >25% in symptoms of the CTS questionnaire and patient's overall satisfaction (5-point Likert scale) at 3 months postoperatively. Success was defined as improvement in both outcome variables. Receiver operating characteristics (ROC) curves and logistic regression analyses were used to assess the best predictive combination of preoperative findings. RESULTS: Success was achieved in 63% of the operated wrists. Utility parameters and area under the ROC curve (AUC) for individual findings was poor, ranging from 0.481 of the nerve conduction study to 0.634 of the cross-sectional area at tunnel outlet. Logistic regression identified the preoperative US parameters as the best predictive variables for success after 3 months. The best predictive combination (AUC=0.708) included a negative Phalen maneuver, plus absence of thenar atrophy, plus less than moderately abnormalities on nerve conduction studies plus a large maximal cross-sectional area along the tunnel by ultrasonography. CONCLUSION: Although cross-sectional area of the median nerve was the only predictor of success after three months of surgical release, isolated preoperative findings are not reliable predictors of success in patients with idiopathic CTS. A combination of findings that include ultrasound improves prediction.

Well-being, distress and health status in a population of adolescent students

The present work explores the psychosocial issues emerging from a large cross-sectional study aimed to assess the prevalence, clinical manifestations, and psychosocial correlates of hyperandrogenism in a population of Italian high school students. Participants were 1804 adolescents, aged between 15 and 19 years, who volunteered to fill in a package of self-report questionnaires (including the Psychosocial Index, the Symptom Questionnaire and Ryff’s Psychological Well-Being scales for the assessment of psychological aspects) and undergo a comprehensive physical examination. Significant gender differences were found with regard to psychological distress, with females reporting higher scores compared with males, but not on well-being dimensions. The relationships of well-being to distress were found to be complex. Although inversely associated, well-being and ill-being appeared to be distinct domains of mental functioning. The evaluation of the moderating effects of well-being in the association between stress and psychological distress indicated that well-being may act as a protective factor, contributing to less pronounced psychological distress as stress levels increased. Higher rates of somatic complaints were found among current smokers. However, substance use (i.e., smoking and drug use) was also found to be positively associated with some well-being dimensions. A considerable number of participants were found to present with disordered eating symptoms, particularly females, and associated higher stress levels and lower quality of life. Sport activities were found to favourably affect psychological health. As to clinical signs of hyperandrogenism, a significant impairment in psychosocial functioning was found among females, whereas no effects on psychological measures could be detected among males. Subgroups of adolescents with distinct clinical and psychological characteristics could be identified by means of cluster analysis. The present study provides new insights into better understanding of the complex relationships between well-being, distress and health status in the adolescent population, with important clinical implications.

Betreuungsbedürfnisse von Patientinnen im Rahmen der gynäkologischen Krebsfrüherkennungsuntersuchung : Entwicklung eines Erfassungsinstrumentes

Da es bis dato kein spezifisches Instrument gibt, um die Betreuungsbedürfnisse von Patientinnen im Rahmen der gynäkologischen Krebsfrüherkennungsuntersuchung zu erfassen, war es das Ziel der vorliegenden explorativen Studie, eben jene subjektiven Betreuungsbedürfnisse aufzudecken und sie in ein praxistaugliches und messbares Format zu überführen - den Fragebogen „Betreuungsbedürfnisse – Gynäkologische Krebsfrüherkennungsuntersuchung (BB-G KFU)“. Wir stellten hierzu folgende Hypothesen auf: Es ist möglich (a) Betreuungsbedürfnisse zu explorieren und in reliablen Skalen abzubilden, (b) die Wichtigkeit der Betreuungsbedürfnisse in Form einer Wertigkeitsrangfolge abzubilden, (c) Determinanten der Betreuungsbedürfnisse (Alter, Sozialstatus, Familienstand, Gesundheitsbezogene Kontrollüberzeugungen) zu detektieren. Wir entwickelten einen Fragebogen auf der Basis einer ausführlichen systematischen Literaturrecherche, Leitfadeninterviews mit gynäkologischen Patientinnen sowie einer Befragung von 18 Experten. Dieser Fragebogen beinhaltete 58 Arzt bezogene Betreuungsbedürfnisse-Items, 12 Arzthelferinnen bezogene Betreuungsbedürfnisse-Items und 21 Praxisorganisation und Praxisstruktur bezogene Betreuungsbedürfnisse-Items. Die Probandinnen bewerteten die Wichtigkeit der Erfüllung jedes Items anhand einer fünfstufigen Antwortskala im Likert-Format (1 = nicht wichtig, 5 = sehr wichtig). Zudem wurden soziodemografische Daten sowie gesundheitsbezogene Kontrollüberzeugungen der Probandinnen erhoben. Im Sinne einer multizentrisch angelegten Querschnittstudie wurde der Fragebogen an 1.000 Patientinnen in zehn gynäkologischen Praxen in drei deutschen Bundesländern ausgegeben. Insgesamt erhielten wir 965 ausgefüllte Fragebögen zurück. Mittels deskriptiver Statistiken konnten die soziodemografischen Daten sowie die einzelnen Betreuungsbedürfnisse-Items ausgewertet werden. Zur Entwicklung reliabler Betreuungsbedürfnis-Skalen wurde der Datensatz einer Hauptkomponentenanalyse (PCA mit Varimax-Rotation) unterzogen. Auf diesem Wege konnte ein Erfassungsinstrument (Fragebogen „Betreuungsbedürfnisse – Gynäkologische Krebsfrüherkennungsuntersuchung (BB-G KFU)“) bestehend aus sieben reliablen Betreuungsbedürfnis-Skalen (BB-S) entwickelt werden, welche die psychosozialen Betreuungsbedürfnisse und -wünsche von Patientinnen mit Bezug auf den Gynäkologen (BB-S-A), die Arzthelferin (BB-S-AH) sowie die Praxisstruktur (BB-S-P) abzubilden vermögen: „Bedürfnis nach Information“ (BB-S-A-I), „Bedürfnis nach Respekt und Einfühlungsvermögen im Rahmen der körperlichen Untersuchung“ (BB-S-A-RE), „Bedürfnis nach Zuwendung und Verfügbarkeit“ (BB-S-A-ZV), „Bedürfnis nach Zuwendung und Service“ (BB-S-AH-ZS), „Bedürfnis nach logistischer Unterstützung“ (BB-S-AH-L), „Bedürfnis nach Basisausstattung und Erreichbarkeit“ (BB-S-P-BE) und „Bedürfnis nach Zusatzausstattung“ (BB-S-P-Z). Die durch die drei arztbezogenen Komponenten (bestehend aus 33 Items) aufgeklärte Gesamtvarianz beträgt 40,29%, die der arzthelferinnenbezogenen 2-Komponentenlösung (11 Items) 48,92%, und die Totalvarianz der zwei Dimensionen mit Bezug auf die Praxisstruktur (19 Items) liegt bei 41,68%. Die Reliabilitäten der sieben Skalen sind als akzeptabel bis sehr gut zu bewerten (Cronbachs α = .71 - .89). Anhand der Korrelationen zum KKG (Fragen zu Kontrollüberzeugungen über Krankheit und Gesundheit von Lohaus und Schmitt) konnten erste positive Hinweise auf die Validität des BB-G KFU gefunden werden. Durch den Vergleich der einzelnen Mittelwerte konnte die hierarchische Organisation der Betreuungsbedürfnisse gemäß ihrer Wichtigkeit sichtbar gemacht werden: Die Arbeit zeigt, dass Patientinnen im Rahmen der gynäkologischen KFU der Informationsvermittlung durch den Arzt (BB-S-A-I; M = 1,51; SD = 0,47) wie auch der ärztlichen Zuwendung und Verfügbarkeit (BB-S-A-ZV; M = 1,39; SD = 0,38) in der Wertigkeitsrangfolge einen besonders hohen Platz einräumen. Die Datenanalysen zeigen zudem eine Abhängigkeit der Betreuungsbedürfnisse vom Alter und vom Sozialstatus der Patientinnen, jedoch nicht vom Familienstand und den gesundheitsbezogenen Kontrollüberzeugungen.

Spa-drain entrapment complicated by suspicions of nonaccidental trauma and epilepsy onset

We present here the case of an adolescent female near-drowning victim who was reportedly discovered submerged and unconscious by family members in a whirlpool spa. Physical examination revealed extensive posterior soft tissue bruising, which raised the suspicion of nonaccidental trauma. Detailed forensic evaluation of the injuries and the scene proved that the soft tissue findings represented an unusual manifestation of whirlpool-spa suction-vent injury. Medical evaluation indicated that epilepsy onset might have contributed to the near-drowning, although forensic evaluation of this possibility was less convincing. In this article we review these rare but important injuries, which have the potential to be confused with child abuse, and detail the atypical presentation and clinically presumed etiologic event in our case.

[Abdominal pain - differential diagnoses and diagnostic strategies in patients with chronic symptoms]

Abdominal pain is a very common complaint in a primary care consultation. The causes of abdominal pain are extremely diverse and range from conditions that require urgent surgical remedy to those without serious underlying pathology where the problem either settles spontaneously, or becomes chronic without any abnormalities on laboratory or clinical workup. While tests are helpful in confirming diagnoses, clinical judgement based on a careful history and physical examination remains extremely important in choosing from the extremely wide differential diagnoses and in the management of the condition. In this article, we will deal with chronically recurrent intermittent abdominal pain. Our aim is especially to provide guidance on the possibility that abdominal pain is a symptom of chronic inflammatory bowel disease (IBD) or an identifiable functional condition and when the diagnosis of irritable bowel syndrome should be made.

[Needle in the haystack - potentially dangerous syncope in childhood]

Syncope is a frequently observed symptom in pediatrics with teenagers being the age group most often affected. In contrast to older age, organic cardiac causes of syncope in child-hood are observed in a minority of only 2-5% of cases, in their majority pediatric syncopes thus are neurocardiogenic in origin. The rare organic cardiac causes that may manifest with syncope are all potentially dangerous entities such as cardiomyopathies, genetic primary electrical disease and some forms of structural heart disease, as well as some other rare diseases such as e.g. primary pulmonary hypertension. These diseases have to be actively looked for or excluded. Guidelines recommend patient evaluation including history, physical examination and ECG, which is sufficient to sort out suspect cases after a syncopal episode.

Genetic evaluation of short stature

After a proper medical history, growth analysis and physical examination of a short child, followed by radiological and laboratory screening, the clinician may decide to perform genetic testing. We propose several clinical algorithms that can be used to establish the diagnosis. GH1 and GHRHR should be tested in children with severe isolated growth hormone deficiency and a positive family history. A multiple pituitary dysfunction can be caused by defects in several genes, of which PROP1 and POU1F1 are most common. GH resistance can be caused by genetic defects in GHR, STAT5B, IGF1, IGFALS, which all have their specific clinical and biochemical characteristics. IGF-I resistance is seen in heterozygous defects of the IGF1R. If besides short stature additional abnormalities are present, these should be matched with known dysmorphic syndromes. If no obvious candidate gene can be determined, a whole genome approach can be taken to check for deletions, duplications and/or uniparental disomies.

Incomplete ovariosalpingectomy and subsequent malignant granulosa cell tumor in a female green iguana (Iguana iguana)

Case Description-A 9-year-old spayed female green iguana (Iguana iguana) was evaluated because of a distended coelom and weight loss. History included a single episode of egg binding and subsequent bilateral ovariosalpingectomy.;Clinical Findings-Physical examination revealed a mass within the coelomic cavity. Ultrasonography revealed a large, irregular mass with hypoechoic regions and coelomic effusion. Clinicopathologic derangements included heterophilia, monocytosis, lymphopenia, basophilia, hypocholesterolemia, hypoproteinemia, and hypercalcemia. Results of cytologic evaluation of the mass were suggestive of malignant epithelial neoplasia, but neoplastic cells were not found in the effusion. An ovarian tumor was suspected on the basis of clinical signs, clinicopathologic findings, and results of cytologic evaluation of the mass.;Treatment and Outcome-Surgical exploration revealed a large left ovary, a normal-appearing contralateral ovary, and a mass in the fat body, all of which were removed and submitted for histologic examination. The histologic diagnosis was granulosa cell tumor with metastasis to the fat body. The patient died 11 months after evaluation, and disseminated granulosa cell tumor was confirmed at necropsy; histologic examination at that time also identified systemic mastocytosis.;Clinical Relevance-Granulosa cell tumors are uncommon in reptiles, and this was the first granulosa cell tumor described antemortem cytologically, histologically, and ultrastructurally in an iguana. Findings in this iguana underscored concerns associated with incomplete oophorectomy of iguanas; cytologic and histopathologic findings were similar to those observed in other domestic animals. Oophorectomy should be considered as an alternative to standard ovariosalpingectomy to avoid potential complications in pet reptiles, and use of microsurgical instruments and vascular clips is advised.
