Rectocele is often associated with anorectal symptoms. Various surgical techniques have been described to repair the rectocele. The surgical results are variable. This study evaluated the results of transanal repair of rectocele, with particular emphasis on the impact of concomitant anismus on postoperative functional outcome. Fifty-nine consecutive females who underwent transanal repair of rectocele for obstructed defecation were prospectively reviewed. All 59 patients were parous with a median parity of 2 (range, 1-6) and a median age of 58 (range, 46-68) years. The median length of follow-up was 19 (range, 6-40) months. Anismus was detected by anorectal physiology and defecography. The functional outcome was assessed by a standard questionnaire, physical examination, anorectal manometry, neurophysiology, and defecography. The quality-of-life index was obtained using a visual analog scale (from 1-10, with 10 being the best). The functional outcome of transanal repair of rectocele was superior in patients without anismus. Forty (93 percent) of the 43 patients without anismus showed improved evacuation after repair compared with 6 (38 percent) of the 16 patients with anismus (Panismus was not present (Panismus, effectively corrects obstructed defecation.

The aim of this study was to evaluate the use of a magnetic resonance (MR)-based classification system of obstructive defecation syndrome (ODS) to guide physicians in patient management. The medical records and imaging series of 105 consecutive patients (90 female, 15 male, aged 21-78 years, mean age 46.1 ± 5.1 years) referred to our center between April 2011 and January 2012 for symptoms of ODS were retrospectively examined. After history taking and a complete clinical examination, patients underwent MR imaging according to a standard protocol using a 0.35 T permanent field, horizontally oriented open-configuration magnet. Static and dynamic MR-defecography was performed using recognized parameters and well-established diagnostic criteria. Sixty-seven out of 105 (64 %) patients found the prone position more comfortable for the evacuation of rectal contrast while 10/105 (9.5 %) were unable to empty their rectum despite repeated attempts. Increased hiatus size, anterior rectocele and focal or extensive defects of the levator ani muscle were the most frequent abnormalities (67.6, 60.0 and 51.4 %, respectively). An MR-based classification was developed based on the combinations of abnormalities found: Grade 1 = functional abnormality, including paradoxical contraction of the puborectalis muscle, without anatomical defect affecting the musculo-fascial structures; Grade 2 = functional defect associated with a minor anatomical defect such as rectocele ≤ 2 cm in size and/or first-degree intussusception; Grade 3 = severe defects confined to the posterior anatomical compartment, including >2 cm rectocele, second- or higher-degree intussusception, full-thickness external rectal prolapse, poor mesorectal posterior fixation, rectal descent >5 cm, levator ani muscle rupture, ballooning of the levator hiatus and focal detachment of the endopelvic fascia; Grade 4 = combined defects of two or three pelvic floor compartments, including cystocele, hysterocele, enlarged urogenital

Recently, the Obstructed Defecation Syndrome score (ODS score) was developed and validated by Renzi to assess clinical staging and to allow evaluation and comparison of the efficacy of treatment of this disorder. Our goal is to validate the Portuguese version of Renzi ODS score, according to the Consensus based Standards for the selection of the Health Measurement Instruments (COSMIN) checklist. Following guidelines for cross-cultural validity, Renzi ODS score was translated into the Portuguese language. Then, a group of patients and healthy controls were invited to fill in the Renzi ODS score at baseline, after 2 weeks and 3 months, respectively. We assessed internal consistency, reliability and measurement error, content and construct validity, responsiveness and interpretability. A total of 113 individuals (77 patients; 36 healthy controls) completed the questionnaire. Seventy and 30 patients repeated the Renzi ODS score after 2 weeks and 3 months respectively. Factor analysis confirmed the unidimensionality of the scale. Cronbach's α coefficient of 0.77 supported item's homogeneity. Weighted quadratic kappa of 0.89 established test-retest reliability. The smallest detectable change at the individual level was 2.66 and at the group level was 0.30. Renzi ODS score and the total (-0.32) and physical (-0.43) SF-36 scores correlated negatively. Patient and control's groups significantly differed (11 points). The change score of Renzi ODS score between baseline and 3 months correlated negatively with the clinical evolution (-0.86). ROC analysis showed minimal important change of 2.00 with AUC 0.97. Neither floor nor ceiling effects were observed. This work validated the Portuguese version of Renzi ODS score. We can now use this reliable, responsive, and interpretable (at the group level) tool to evaluate Portuguese ODS patients.

Defecography is the gold standard for assessing functional anorectal disorders but is limited by the need for a specific radiologic environment, exposure of patients to radiation, and inability to show all anatomic structures involved in defecation. Echodefecography is a 3-dimensional dynamic ultrasound technique developed to overcome these limitations. This study was designed to validate the effectiveness of echodefecography compared with defecography in the assessment of anorectal dysfunctions related to obstructed defecation. Multicenter, prospective observational study. Women with symptoms of obstructed defecation. Six centers for colorectal surgery (3 in Brazil, 1 in Texas, 1 in Florida, and 1 in Venezuela). Defecography was performed after inserting 150 mL of barium paste in the rectum. Echodefecography was performed with a 2050 endoprobe through 3 automatic scans. The κ statistic was used to assess agreement between echodefecography and defecography in the evaluation of rectocele, intussusception, anismus, and grade III enterocele. Eighty-six women were evaluated: median Wexner constipation score, 13.4 (range, 6-23); median age, 53.4 (range, 26-77) years. Rectocele was identified with substantial agreement between the 2 methods (defecography, 80 patients; echodefecography, 76 patients; κ = 0.61; 95% CI = 0.48-0.73). The 2 techniques demonstrated identical findings in 6 patients without rectocele, and in 9 patients with grade I, 29 with grade II, and 19 patients with grade III rectoceles. Defecography identified rectal intussusception in 42 patients, with echodefecography identifying 37 of these cases, plus 4 additional cases, yielding substantial agreement (κ = 0.79; 95% CI = 0.57-1.0). Intussusception was associated with rectocele in 28 patients for both methods (κ = 0.62; 95% CI = 0.41-0.83). There was substantial agreement for anismus (κ = 0.61; 95% CI = 0.40-0.81) and for rectocele combined with anismus (κ = 0.61; 95% CI = 0.40-0.82). Agreement for

Recent developments in diagnostic imaging have made gynecologists, colorectal surgeons and gastroenterologists realize as never before that they share a common interest in anorectal and pelvic floor dysfunction. While we often may be using different words to describe the same phenomenon (e.g. anismus/vaginismus) or attributing different meanings to the same words (e.g. rectocele), we look after patients with problems that transcend the borders of our respective specialties. Like no other diagnostic modality, imaging helps us understand each other and provides new insights into conditions we all need to learn to investigate better in order to improve clinical management. In this review we attempt to show what modern ultrasound imaging can contribute to the diagnostic work-up of patients with posterior vaginal wall prolapse, obstructed defecation and rectal intussusception/prolapse. In summary, it is evident that translabial/perineal ultrasound can serve as a first-line diagnostic tool in women with such complaints, replacing defecation proctography and MR proctography in a large proportion of female patients. This is advantageous for the women themselves because ultrasound is much better tolerated, as well as for healthcare systems since sonographic imaging is much less expensive. However, there is a substantial need for education, which currently remains unmet. Copyright © 2012 ISUOG. Published by John Wiley & Sons, Ltd.

This study aims to show pelvic floor dysfunctions in women with obstructed defecation syndrome (ODS), comparing nulliparous to those with vaginal delivery or cesarean section using the echodefecography (ECD). Three hundred seventy female patients with ODS were reviewed retrospectively and were divided in Group I-105 nulliparous, Group II-165 had at least one vaginal delivery, and Group III-comprised of 100 patients delivered only by cesarean section. All patients had been submitted to ECD to identify pelvic floor dysfunctions. No statistical significance was found between the groups with regard to anorectocele grade. Intussusception was identified in 40% from G I, 55.0% from G II, and 30.0% from G III, with statistical significance between Groups I and II. Intussusception was associated with significant anorectocele in 24.8%, 36.3%, and 18% patients from G I, II, and III, respectively. Anismus was identified in 39.0% from G I, 28.5% from G II, and 60% from G III, with statistical significance between Groups I and III. Anismus was associated with significant anorectocele in 22.8%, 15.7%, and 24% patients from G I, II, and III, respectively. Sigmoidocele/enterocele was identified in 7.6% from G I, 10.9% G II, and was associated with significant rectocele in 3.8% and 7.3% patients from G I and II, respectively. The distribution of pelvic floor dysfunctions showed no specific pattern across the groups, suggesting the absence of a correlation between these dysfunctions and vaginal delivery.

Anteriorly displaced anus is an anomaly that is debated with regard to its nomenclature, diagnosis and management. To describe MRI anatomy of the anal canal in children with anteriorly displaced anus and its impact on the process of defecation. We prospectively examined ten children (7 girls, 3 boys; age range 7 months to 8 years, mean 3 years) with anteriorly displaced anus between August 2009 and April 2012. Noncontrast MRI examinations were performed on a 1.5-T magnet. T1- and T2-weighted turbo spin-echo images were acquired in axial, sagittal and coronal planes of the pelvis. The anorectal angle and the relative hiatal distance were measured in mid-sagittal images, and compared with those of a control group using the Mann-Whitney test. In children with anteriorly displaced anus, no anatomical abnormality was depicted at the level of the proximal anal canal. However, the distal anal canal was displaced anteriorly, running out its external muscle cuff, which remained un-displaced at the usual site of the anus. This changes the orientation of the central axis of the anal canal by passing across instead of along the fibers of the longitudinal muscle coat. Children with anteriorly displaced anus had a more obtuse anorectal angle (mean 112.1 ), which was significantly greater than that of the control group (mean 86.2 ). MRI is a valuable tool in studying the anatomy of the anal canal in children with anteriorly displaced anus. The abnormal orientation of the longitudinal muscle across the anal canal can explain the obstructed defecation in these children. Based on this study, it might be of interest to use MRI in studying equivocal cases and children with unexplained constipation. (orig.)

Obstructed defecation syndrome (ODS), most commonly found in females, can be treated by a transanal or abdominal approach with good success rate. Nevertheless, patients may experience de novo or persisting pelvic floor dysfunctions after surgery. The aim of this study was to compare the functional outcome of stapled transanal rectal resection (STARR) and ventral rectopexy (VRP) in a series of ODS patients. Forty-nine female patients who had surgery for ODS between 2006 and 2016 were retrospectively evaluated: 28 (median age 60 years, IQR 54-69 years) had VRP and 21 (median age 58 years, IQR 51-66 years) had STARR. ODS was scored with the ODS score while the overall pelvic floor function was assessed with the three axial perineal evaluation (TAPE) score. Quality-of-life was evaluated by the patient assessment of constipation quality-of-life (PAC-Qol) questionnaire administered preoperatively and after 1 year of follow-up. The preoperative median ODS score and TAPE score were comparable in both groups. After a median follow-up of 12 months (range 12-18 months), the median ODS score was 12 (range 10-20) in the STARR group and 9 (range 3-15) in the VRP one (p = 0.02), while the median TAPE score was 70.5 (IQR 60.6-77.3) in the former and 76.8 (IQR 70.2-89.7) in the latter (p = 0.01). Postoperatively the physical domain of the PAC-QoL score had a median value of 2.74 (IQR 1.7-3.75) in the STARR group compared to 1.5 (IQR 1-2.5) in the VRP group (p = 0.03). No major complications were recorded in either group. VRP and STARR can improve defecation in patients with ODS with minimal complications, but the overall pelvic wellness evaluated by the TAPE score improves significantly only after VRP, suggesting a better performance of VRP than STARR when overall pelvic floor function is concerned.

Surgical treatment of constipation and obstructed defecation (OD) carries frequent recurrences, as OD is an 'iceberg syndrome' characterized by 'underwater rocks' or occult diseases which may affect the outcome of surgery. The aim of this study was to evaluate occult disorders, in order to alert the clinician of these and minimize failures. One hundred consecutive constipated patients with OD symptoms, 81 women, median age 52 years, underwent perineal examination, proctoscopy, anorectal manometry and anal/vaginal ultrasound (US). Anorectal physiology and imaging tests were also carried out when indicated, as well as psychological and urogynaecological consultations. Symptoms were graded using a modified 1-20 constipation score. Both evident (e.g. rectocele) and occult (e.g. anismus) diseases were prospectively evaluated using a novel 'iceberg diagram'. The type of treatment, whether conservative or surgical, was also recorded. Fifty-four (54%) patients had both mucosal prolapse and rectocele. All patients had at least two occult OD-related diseases, 66 patients had at least three of them: anxiety-depression, anismus and rectal hyposensation were the most frequent (66%, 44% and 33%, respectively). The median constipation score was 11 (range 2-20), the median number of 'occult disorders' was 5 (range 2-8). Conservative treatment was carried out in most cases. Surgery was carried out in 14 (14%) patients. The novel 'iceberg diagram' allowed the adequate evaluation of OD-related occult diseases and better selection of patients for treatment. Most were managed conservatively, and only a minority were treated by surgery.

Full text: Idiopathic constipation may be due to delayed colonic transit or ano-rectal dysfunction and obstructive defecation. The aim of this study was to relate patterns of colonic transit to results of ano-rectal manometry. Sixteen patients (4 males, 12 females, age 20-58 years) were studied. All underwent ano-rectal manometric studies and colonic transit studies. The transit studies were performed following the oral ingestion of 4 MBq 67 Gacitrate with images performed at 6, 24, 48 and 72 h. Computed data on half clearance times (T 1/2 ), mean activity positions (MAP) and segmental tracer retention were obtained. Five patients had normal ano-rectal manometry, 7 decreased rectal sensation and 4 absent or paradoxical ano-rectal reflex (anismus). The T 1/2 for subjects with normal manometry was 78.5 ± 11.9 h, decreased rectal sensation 73 ± 4.9 h and the anismus group 52 ± 12.1 h (P < 0.05). Total retention at 72 h was less at 56 ± 3.73 h in the anismus group compared to normal manometry (74.7 ± 12.2) and decreased rectal sensation (90.7 ± 12.1), with higher MAP and less tracer in the right colon at 48 h in the anismus group (P < 0.05). The results indicate that colonic transit studies in constipated patients with anismus have different patterns to those with normal anorectal manometry or decreased rectal sensation

Full Text Available Sleep-related breathing disorders in children are a clinical problem which is more and more often diagnosed by doctors nowadays. They can be the basis for diagnosing obstructive sleep apnoea syndrome that causes a number of complications: lowering the quality of life, behavioural problems, complications involving cardiovascular system. The incidence of obstructive sleep apnoea syndrome in the paediatric population is estimated to be at the level of 2%. The symptoms of obstructive sleep apnoea syndrome can be divided into daytime and night ones. Night symptoms in children include: snoring, apnoea, breathing with open mouth (both during the day and at night, dry tongue and mouth during sleep, agitated sleep in unnatural positions. Among daytime symptoms of obstructive sleep apnoea syndrome there are: irritability, aggressiveness, hyperactivity, attention deficit disorder, delayed development and growth pattern (mainly failure to thrive, learning problems, morning headaches. Parents often do not connect the night and daytime symptoms with the possible development of obstructive sleep apnoea syndrome in their children. The main predisposing factor of obstructive sleep apnoea syndrome in children is adenotonsillar hypertrophy. Effective and in most cases preferred treatment for the management of obstructive sleep apnoea syndrome in children is adenotonsillectomy. Polysomnography and polygraphy are diagnostic tools helpful in the study of sleep-related disorders. The objective of this study was to systematise the knowledge on the epidemiology, aetiology, clinical image and prevention of obstructive sleep apnoea syndrome in children.

Stapled transanal rectal resection (STARR) is a promising new treatment for obstructed defecation syndrome (ODS). It may be performed using either a double-stapling technique (PPH-STARR) or with the new Contour Transtar (CT) device. The aim of this study was to evaluate the two techniques with respect to morbidity and functional outcomes. Patients presenting with ODS were evaluated using standardized clinical and radiological investigations and prospectively entered into a database. A total of 150 Patients were treated with either PPH-STARR (n = 68) or CT (n = 82) and further evaluated at 12 month postoperatively. The mean size of the resected specimen was 27 cm(2) (SD +/-4.86 cm(2)) in the PPH-STARR group and 46 cm(2) (SD +/-10.6 cm(2)) in the CT group [P < 0.001]. Morbidity was 7.3% (n = 5) in the PPH-STARR group and 7.5% (n = 6) in the CT group. The most common complication was minor postoperative bleeding in both groups (PPH-STARR: n = 2, 2.9%; CT: n = 2, 2.4%) Overall there were no septic complications and no surgical re-interventions. There was a tendency for more postoperative pain following CT (n = 3, 3.6%) as compared with PPH-STARR (n = 1, 1.4%). Constipation Scores (CCS) were 15.50 +/- 5.71 in the PPH-STARR group and 15.70 +/- 5.84 in the CT group preoperatively and decreased significantly to 8.25 (SD +/-1.45) and 8.01 (SD +/-2.31) 12-months after surgery. Values did not differ significantly between the two groups. Contour Transtar is as safe and effective as PPH-STARR and provides a true circumferential resection of rectal intussusception. This may benefit selected patients and result in improved long-term durability of the technique.

[Correlation between obstructive apnea syndrome and difficult airway in ENT surgery].

ENT patients with obstructive sleep apnea syndrome have a tendency of collapsing the upper airways in addition to anatomical obstacles. Obstructive sleep apnea syndrome is related to the increased risk of difficult airway and also increased perioperative complications. In order to identify these patients in the preoperative period, the STOP Bang questionnaire has been highlighted because it is summarized and easy to apply. Evaluate through the STOP Bang questionnaire whether patients undergoing ENT surgery with a diagnosis of obstructive sleep apnea syndrome have a higher risk of complications, particularly the occurrence of difficult airway. Measurements of anatomical parameters for difficult airway and questionnaire application for clinical prediction of obstructive sleep apnea syndrome were performed in 48 patients with a previous polysomnographic study. The sample detected difficult airway in about 18.7% of patients, all of them with obstructive sleep apnea syndrome. This group had older age, cervical circumference > 40cm, ASA II and Cormack III/IV. Patients with obstructive sleep apnea syndrome had higher body mass index, cervical circumference, and frequent apnea. In subgroup analysis, the group with severe obstructive sleep apnea syndrome showed a significantly higher SB score compared to patients without this syndrome or with a mild/moderate obstructive sleep apnea syndrome. The STOP Bang questionnaire was not able to predict difficult airway and mild obstructive sleep apnea syndrome, but it identified marked obstructive sleep apnea syndrome. All patients with difficult airway had moderate and marked obstructive sleep apnea syndrome, although this syndrome did not involve difficult airway. The variables Cormack III/IV and BMI greater than 35 Kg.m -2 were able to predict difficult airway and obstructive sleep apnea syndrome, respectively.

Obstructive sleep apnea syndrome is a common problem among children and is recognized as a cause of significant medical morbidity. Since the 1980s, it has been suggested that obstructive sleep apnea syndrome is a risk factor for growth failure in children. In many cases, it has been shown that growth failure is reversible once the obstructive sleep apnea syndrome is resolved. The objectives of this study were to analyze and compare growth failure prevalence in a Mediterranean population of children with obstructive sleep apnea syndrome and healthy children matched in age and sex, and to assess the effectiveness of tonsillectomy and adenoidectomy in resolving growth retardation. We compared 172 children with obstructive sleep apnea syndrome (apnea-hypopnea index ≥ 3) who had undergone tonsillectomy and adenoidectomy with 172 healthy controls in terms of key anthropometric parameters. Most of the criteria used for growth failure were higher to a statistically significant degree in the study group vs the control group: height-for-age ≤ 3rd percentile (7.56% vs 2.91%; p = 0.044), weight-for-age ≤ 5th percentile (9.30% vs 2.33%; p = 0.005), weight-for-age ≤ 3rd percentile (8.14% vs 2.33%; p = 0.013) and height and/or weight for-age ≤ 5th percentile (13.95% vs 5.81%; p = 0.009). The height-for-age ≤ 5th percentile was almost at the limit of statistical significance (8.72% for the study group vs 4.65% for the control group; p = 0.097). At one-year post-surgery follow-up, 10 of 15 children with height-for-age ≤ 5th percentile had achieved catch-up growth (66.6%), and 14 of 24 children with height- and/or weight-for-age ≤ 5th percentile had normalized growth (58.33%). For children with failure to thrive or who have growth failure, physicians should consider the possibility of obstructive sleep apnea. A significant number of children with obstructive sleep apnea concurrent with growth failure could benefit from

Treating Pelvic Floor Disorders of Defecation: Management or Cure?

Science.gov (United States)

Rao, Satish S.C.; Go, Jorge T.

2013-01-01

Pelvic floor disorders that affect defecation consist of structural disorders such as rectocele and functional disorders such as dyssynergic defecation. Evaluation includes a good history and physical examination, a careful digital rectal exam, as well as physiological tests such as anorectal manometry, colonic transit study and balloon expulsion test. Defecography and dynamic magnetic resonance imaging may facilitate detection of structural defects. Their management consists of education and counseling regarding bowel function, diet, laxatives and behavioral therapies. Recently, several randomized clinical trials have shown that biofeedback therapy is effective in dyssynergic defecation. Dyssynergia may also co-exist in structural disorders such as solitary rectal ulcer syndrome or rectocele. Hence, before proceeding with surgery, neuromuscular training or biofeedback should be considered. Several surgical approaches including stapled transanal rectal resection (STARR) have been advocated, but there is lack of well controlled randomized studies and their efficacy is unproven.

Cushing's syndrome is rare in pregnancy but can cause spontaneous abortion, stillbirth or premature birth. We report a case of transient hypertrophic obstructive cardiomyopathy in a newborn whose mother had hypercortisolism due to a primary adrenal lesion. There was no family history of hypertrophic obstructive cardiomyopathy. Follow-up revealed complete resolution of the cardiac abnormalities in the infant. Cushing's syndrome in the mother resolved after delivery. Although maternal hypercortisolism seldom results in symptomatic hypercortisolism in the newborn, hypertrophic obstructive cardiomyopathy can occur.

Full Text Available In this study we evaluated the incidence and severity of obstructive sleep apnea and Obstructive sleep apnea syndrome in patients with thromboangiitis obliterans for reduction of crisis. In 40 patients with Buerger's disease daily sleepiness and risk of Obstructive sleep apnea were evaluated using the Epworth sleeping scale (ESS and the Stop-Bang score. An Apnea-link device was used for evaluation of chest motion, peripheral oxygenation, and nasal airflow during night-time sleep. The apnea/hypopnea index (AHI and respiratory tdisurbance index were used for Obstructive sleep apnea syndrome diagnosis. All subjects were cigarette smokers and 80% were opium addicted. The prevalence of Obstructive sleep apnea (AHI>5 was 80%, but incidence of Obstructive sleep apnea syndrome (AHI>5 + ESS≥10 was 5% (2/40. There was no association between duration or frequency of hospitalization and Obstructive sleep apnea syndrome (P=0.74 and 0.86, respectively. In addition, no correlation between ESS and Stop-Bang scores and AHI was observed (P=0.58 and 0.41, respectively. There was an inverse correlation between smoking rate and AHI (P=0.032, r = −0.48. We did not find an association between Buerger's disease and Obstructive sleep apnea syndrome. Although the AHI was high (80% and daily sleepiness was low. The negative correlation of smoking with AHI and on the other hand daily napping in addiction may be caused by the absence of a clear relationship between Obstructive sleep apnea syndrome and Buerger's disease.

Full Text Available Objective: To provide an overview of the healthcare and societal consequences and costs of untreated obstructive sleep apnea syndrome. Data sources: PubMed database for English-language studies with no start date restrictions and with an end date of September 2014. Methods: A comprehensive literature review was performed to identify all studies that discussed the physiologic, clinical and societal consequences of obstructive sleep apnea syndrome as well as the costs associated with these consequences. There were 106 studies that formed the basis of this analysis. Conclusions: Undiagnosed and untreated obstructive sleep apnea syndrome can lead to abnormal physiology that can have serious implications including increased cardiovascular disease, stroke, metabolic disease, excessive daytime sleepiness, work-place errors, traffic accidents and death. These consequences result in significant economic burden. Both, the health and societal consequences and their costs can be decreased with identification and treatment of sleep apnea. Implications for practice: Treatment of obstructive sleep apnea syndrome, despite its consequences, is limited by lack of diagnosis, poor patient acceptance, lack of access to effective therapies, and lack of a variety of effective therapies. Newer modes of therapy that are effective, cost efficient and more accepted by patients need to be developed.

2017-08-01

Full Text Available Obstructive sleep apnea-hypopnea syndrome (OSAHS is a disease characterized by recurrent upper airway obstruction (UAO, with decreased airflow, intermittent hypoxemia, and awakening during sleep. Two essential factors are related to the pathophysiology of OSAHS: anatomical alterations and reduction or absence of neural control. While studying OSAHS, the site or sites of obstruction of the UA should be identified; they may extend from the nasal wings to the hypopharynx. Another important factor in this syndrome is the nervous influence on muscle tone of the hypopharynx, as well as the changes in blood pH, which are secondary to micro-arousals. Body position and sleep stage determine the severity. The pathophysiology of OSAHS should be understood to properly study a patient and provide the best treatment option.

2008-02-15

Chronic obstructive pulmonary disease (COPD) and sleep apnea-hypopnea syndrome (SAHS) are both common diseases affecting respectively 10 and 5% of the adult population over 40 years of age, and their coexistence, which is denominated overlap syndrome, can be expected to occur in about 0.5% of this population. A recent epidemiologic study has shown that the prevalence of SAHS is not higher in COPD than in the general population, and that the coexistence of the two conditions is due to chance and not through a pathophysiologic linkage between these two diseases. Patients with overlap have a more important sleep-related O(2) desaturation than do patients with COPD with the same degree of bronchial obstruction. They have an increased risk of developing hypercapnic respiratory insufficiency and pulmonary hypertension when compared with patients with SAHS alone and with patients with "usual" COPD. In patients with overlap, hypoxemia, hypercapnia, and pulmonary hypertension can be observed in the presence of mild to moderate bronchial obstruction, which is different from "usual" COPD. Therapy of the overlap syndrome consists of nasal continuous positive airway pressure or nocturnal noninvasive ventilation (NIV), with or without associated nocturnal O(2). Patients who are markedly hypoxemic during daytime (Pa(O(2)) < 55-60 mm Hg) should be given conventional long-term O(2) therapy in addition to nocturnal ventilation.

Chronic obstructive parotitis related to Sjogren syndrome is not uncommon, but it is rarely reported in the literature. The aim of this study was to describe our experience in the treatment of chronic obstructive parotitis related to Sjogren syndrome. Seventeen cases of chronic obstructive parotitis related to Sjogren syndrome treated with sialendoscopy from June 2014 to June 2015 at the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medical University, were retrospectively reviewed. The cohort underwent ultrasonography, salivary gland scintigraphy, and sialography before sialendoscopy. All patients were asked to complete a visual analogue scale (VAS) evaluation before and 6 months after surgery. A paired t test was conducted, and P parotid glands) successfully underwent interventional sialendoscopy under local anesthesia. The mean preoperative VAS score was 6, and the mean VAS score 6 months after sialendoscopy was significantly lower at 4.5 (P < .05). Interventional sialendoscopy plays a significant role in the treatment of chronic obstructive parotitis related to Sjogren syndrome. Copyright © 2016 Elsevier Inc. All rights reserved.

Full Text Available Background: As obesity increases, the frequency of obstructive sleep apnea and obesity hypoventilation syndrome increases also. However, obesity hypoventilation syndrome frequency is not known, as capnography and arterial blood gas analysis are not routinely performed in sleep laboratories. Aims: To investigate the frequency and predictors of obesity hypoventilation syndrome in obese subjects. Study Design: Retrospective clinical study Methods: Obese subjects who had arterial blood gas analysis admitted to the sleep laboratory and polysomnography were retrospectively analyzed. Subjects with restrictive (except obesity and obstructive pulmonary pathologies were excluded. Demographics, Epworth-Sleepiness-Scale scores, polysomnographic data, arterial blood gas analysis, and spirometric measurements were recorded. Results: Of the 419 subjects, 45.1% had obesity hypoventilation syndrome. Apnea hypopnea index (p<0.001, oxygen desaturation index (p<0.001 and sleep time with SpO2<90% (p<0.001 were statistically higher in subjects with obesity hypoventilation syndrome compared to subjects with eucapnic obstructive sleep apnea. The nocturnal mean SpO2 (p<0.001 and lowest SpO2 (p<0.001 were also statistically lower in subjects with obesity hypoventilation syndrome. Logistic regression analysis showed that the lowest SpO2, oxygen desaturation index, apnea hypopnea index and sleep time with SpO2 <90% were related factors for obesity hypoventilation syndrome. Conclusion: Obesity hypoventilation syndrome should be considered when oxygen desaturation index, apnea hypopnea index and sleep time with SpO2 <90% are high

Goltz-Gorlin syndrome is a rare autosomal dominant hereditary disease associated with a high rate of spontaneous mutation. Diagnosis is based on clinically defined major and minor criteria. The disease is caused by a gene mutation locating to chromosome 9q22-31. We report on a young Goltz-Gorlin syndrome patient with obstructive sleep apnea syndrome. Due to intolerance to continuous positive airway pressure (CPAP) therapy and in order to avoid a tracheotomy, we opted for an alternative therapy comprising interdisciplinary multi-level surgery.

Overlap Syndrome in Respiratory Medicine: Asthma and Chronic Obstructive Pulmonary Disease

2014-02-01

Full Text Available Asthma and chronic obstructive pulmonary disease (COPD are highly prevalent chronic diseases in the general population. Both are characterized by similar mechanisms: airway inflammation, airway obstruction, and airway hyperresponsiveness. However, the distinction between the two obstructive diseases is not always clear. Multiple epidemiological studies demonstrate that in elderly people with obstructive airway disease, as many as half or more may have overlapping diagnoses of asthma and COPD. A COPD-Asthma overlap syndrome is defined as an airflow obstruction that is not completely reversible, accompanied by symptoms and signs of increased obstruction reversibility. For the clinical identification of overlap syndrome COPD-Asthma Spanish guidelines proposed six diagnostic criteria. The major criteria include very positive bronchodilator test [increase in forced expiratory volume in one second (FEV1 ≥15% and ≥400 ml], eosinophilia in sputum, and personal history of asthma. The minor criteria include high total IgE, personal history of atopy and positive bronchodilator test (increase in FEV1 ≥12% and ≥200 ml on two or more occasions. The overlap syndrome COPD-Asthma is associated with enhanced response to inhaled corticosteroids due to the predominance of eosinophilic bronchial inflammation.The future clinical studies and multicenter clinical trials should lead to the investigation of disease mechanisms and simultaneous development of the novel treatment.

Full Text Available The paper presents the data on research of aspiration syndrome prevalence among young children treated in the City children’s pulmonary department due to protracted course of obstructive bronchitis. The structure of microaspiration reasons in young children was studied (2010–2015. The most significant reasons of microaspiration syndrome development were revealed depending on children age. Modified questionnaire for the parents was used to collect anamnesis effectively. The children with perinatal impairment of nervous system, preterm children, and the children with morphological and physio­logical nasopharyngeal defects, with muscular dystonia are firstly in risk group for microaspiration syndrome. Microaspiration may manifest with frequent regurgitation, vomiting during cough, meal leaking from the nose, correlation of coughing fit with feeding, exacerbation or development of coughing in prone position, fit of night coughing and asphyxia, long-term hacking after cough attack. Pediatricians are recommended to observe attentively their patients during each feeding as dysphagy could be inconstant. Microaspiration syndrome is a challenging for diagnosis and requires complex approach, as mostly diagnostic procedures are invasive. Timely diagnosis and treatment of microaaspiration syndrome allow decrease respiratory diseases rate in young children and reduce obstructive bronchitis duration.

Several studies have investigated the prevalence and risk factors of insomnia in subjects with obstructive sleep apnea syndrome. However, few studies have investigated the prevalence and risk factors for obstructive sleep apnea syndrome in insomnia sufferers. Thus, the aim of this study was to examine the prevalence and risk factors of moderate to severe obstructive sleep apnea syndrome in a large sample of insomnia sufferers. Data from 1311 insomnia sufferers who were recruited from the research database of the sleep laboratory of the Erasme Hospital were analysed. An apnea-hypopnea index of ≥15 events per hour was used as the cut-off score for moderate to severe obstructive sleep apnea syndrome. Logistic regression analyses were conducted to examine clinical and demographic risk factors of moderate to severe obstructive sleep apnea syndrome in insomnia sufferers. The prevalence of moderate to severe obstructive sleep apnea syndrome in our sample of insomnia sufferers was 13.88%. Multivariate logistic regression analysis revealed that male gender, snoring, excessive daytime sleepiness, lower maintenance insomnia complaint, presence of metabolic syndrome, age ≥ 50 & 30 kg/m 2 , and CRP >7 mg/L were significant risk factors of moderate to severe obstructive sleep apnea syndrome in insomnia sufferers. Moderate to severe obstructive sleep apnea syndrome is a common pathology in insomnia sufferers. The identification of these different risk factors advances a new perspective for more effective screening of moderate to severe obstructive sleep apnea syndrome in insomnia sufferers.

Full Text Available The nasal polyposis is a chronic inflammatory process of the nasal mucosa. Although it is rare in children, there may be also association with cystic fibrosis and primary ciliary dyskinesia. About 50% of primary ciliary dyskinesia patients develop situs inversus and it is known as Kartagener's syndrome. The Kartagener's sydrome is a rare autosomal recessive disorder characterized by sinusitis, bronchiectasis, situs inversus. Clinically, patients present to the otolaryngologist with nasal obstruction. We as pediatricians, should consider nasal polyposis as a rare cause of nasal obstruction in children. In the presence of recurrent upper and lower respiratory tract infections accompanying nasal polyposis, Kartagener's syndrome must be kept in mind as a rare reason.

Obstructive sleep apnea syndrome and laryngopharyngeal reflux are diseases with a high prevalence in the overall population; however, it remains unclear whether they are diseases with the same risk factors present in the same populations or if there is any association between them. To evaluate and determine the prevalence of laryngopharyngeal reflux in patients with moderate and severe obstructive apnea syndrome and also to determine its predictive factors. Historical cohort, cross-sectional study of patients aged 18-70 years, referred to a tertiary service Otorhinolaryngology outpatient clinic with a polysomnographic diagnosis of moderate or severe obstructive sleep apnea syndrome. The reflux symptom index questionnaire and the reflux finding score at indirect videolaryngoscopy were applied to the assessed population, considering the inclusion and exclusion criteria. Fifty-six patients were evaluated, of which 64.3% had a positive laryngopharyngeal reflux (positive reflux symptom index and/or positive endolaryngeal reflux finding score). Body mass index was a predictor of reflux presence in this group of patients with moderate to severe obstructive sleep apnea syndrome. In patients with positive score for endoscopic findings and reflux symptom index (12.3%), there was a trend toward significance for a higher mean apnea-hypopnea index and a higher percentage of sleep time with oxyhemoglobin saturation below 90% (p=0.05). The prevalence of laryngopharyngeal reflux was higher in this group of patients with moderate to severe obstructive sleep apnea syndrome, and the body mass index was a predictor of laryngopharyngeal reflux in these patients. There was a trend toward greater oxyhemoglobin desaturation in patients with a positive score for reflux symptoms index (RSI) and reflux finding score (RFS).

Chronic obstructive pulmonary disease (COPD) and the obstructive sleep apnoea-hypopnoea syndrome (OSAHS) are both common diseases affecting respectively 10 and 5% of the adult population over 40 years of age. Their coexistence, which is denominated "Overlap Syndrome", can be expected to occur in about 0.5% of this population. Two recent epidemiologic studies have shown that the prevalence of OSAHS is not higher in COPD than in the general population, and that the coexistence of the two conditions is due to chance and not through a pathophysiological linkage. Patients with "overlap" have a higher risk of sleep-related O(2) desaturation than do patients with COPD alone and the same degree of bronchial obstruction. They have an increased risk of developing hypercapnic respiratory failure and pulmonary hypertension when compared with patients with OSAHS alone and with patients with "usual" COPD. In patients with overlap, hypoxaemia, hypercapnia, and pulmonary hypertension can be observed in the presence of mild to moderate bronchial obstruction, which is different from "usual" COPD. Treatment of the overlap syndrome consists of nasal continuous positive airway pressure or nocturnal non-invasive ventilation (NIV), with or without nocturnal O(2).

Obstructive sleep apnoea syndrome in children and anaesthesia

Directory of Open Access Journals (Sweden)

A Rudra

2010-01-01

Full Text Available Obstructive sleep apnoea syndrome (OSAS is a common medical disorder among adults, which is increasingly being recognized in children too. It is a breathing disorder characterized by upper airway obstruction with or without intermittent complete obstruction that disrupts normal breathing during sleep. Anatomical and neuromuscular disorders are mainly responsible for this disorder. This disorder leads to a state of chronic hypoxemia, which has significant cardiac, pulmonary and central nervous system implications. Diagnosis of OSAS is based on thorough history and clinical examination along with appropriate sleep studies including polysomnography. The mainstay of treatment of paediatric OSAS is adenotonsillectomy. Good anaesthetic practice in Paediatric patients with OSAS revolves around good and ideal airway management. Early detection of airway obstruction, intense monitoring to warn of impending airway problems and appropriate and early intervention of airway compromise are good anaesthetic practices. Coexisting medical problems should be adequately addressed and safe analgesic techniques in the perioperative period go towards improving outcomes in patients with paediatric OSAS.

The prevalence of obstructive sleep apnea-hypopnea syndrome in the general childhood population is 1-2% and the most common cause is adenotonsillar hypertrophy. However, beyond adenotonsillar hypertrophy, there are other highly prevalent causes of this syndrome in children. The causes are often multifactorial and include muscular hypotonia, dentofacial abnormalities, soft tissue hypertrophy of the airway, and neurological disorders). Collaboration between different specialties involved in the care of these children is essential, given the wide variability of conditions and how frequently different factors are involved in their genesis, as well as the different treatments to be applied. We carried out a wide literature review of other causes of obstructive sleep apnea-hypopnea syndrome in children, beyond adenotonsillar hypertrophy. We organised the prevalence of this syndrome in each pathology and the reasons that cause it, as well as their interactions and management, in a consistent manner.

The acute electrocardiographic changes during apneic episodes in patients with sleep apnea are well known. Long-term electro-cardiographic changes in these patients are not well studied. We conducted a retrospective case-control study to assess the electrocardiographic changes in African-American patients with established obstructive sleep apnea syndrome (OSA). A significant percentage of patients with OSA had abnormal EKGs as compared to the control group. The effect of sleep apnea on the cardiovascular system is more complex in African-Americans due to higher prevalence of co-morbid conditions. Seventy-three percent of our patients with OSA had metabolic syndrome.

Psychological factors are well known to be involved in onset and exacerbation of IBS. A few studies have reported effectiveness of traditional herbal (Kampo medicines in IBS treatment. Yokukansan (YKS has been shown to have anti-stress and anxiolytic effects. We investigated the effect of YKS on defecation induced by stress and involvement of oxytocin (OT, a peptide hormone produced by the hypothalamus, in order to elucidate the mechanism of YKS action. Methods and results: Male Wistar rats were divided into four groups; control, YKS (300 mg/kg PO-treated non-stress (YKS, acute stress (Stress, and YKS (300 mg/kg PO-treated acute stress (Stress+YKS groups. Rats in the Stress and Stress+YKS groups were exposed to a 15-min psychological stress procedure involving novel environmental stress. Levels of plasma OT in the YKS group were significantly higher compared with those in the Control group (P < 0.05, and OT levels in the Stress+YKS group were remarkably higher than those in the other groups (P < 0.01. Next, rats were divided into four groups; Stress, Stress+YKS, Atosiban (OT receptor antagonist; 1 mg/kg IP-treated Stress+YKS (Stress+YKS+B, and OT (0.04 mg/kg IP-treated acute stress (Stress+OT groups. Rats were exposed to acute stress as in the previous experiment, and defecation during the stress load was measured. Administration of YKS or OT significantly inhibited defecation; however, administration of Atosiban partially abolished the inhibitory effect of YKS. Finally, direct action of YKS on motility of isolated colon was assessed. YKS (1 mg/mL, 5 mg/mL did not

Sinusoidal obstruction syndrome (SOS) is characterized by damage to small hepatic vessels affecting particularly sinusoidal endothelium. Damaged sinusoids can be associated with a partial or complete occlusion of small hepatic veins, hence the previous denomination of hepatic veno-occlusive disease (VOD). Exposure to certain exogenous toxins appears to be specific to this condition and is frequently included in its definition. Typical histopathological features of SOS in a liver biopsy specimen are presented in the text. The purpose of this article is to provide an overview on the different entities corresponding to this general definition. Such entities include: (i) liver disease related to pyrrolizidine alcaloids; (ii) liver injury related to conditioning for hematopoietic stem cell transplantation; (iii) vascular liver disease occurring in patients treated with chemotherapy for liver metastasis of colorectal cancer; and (iv) other liver diseases related to toxic agents.

Upper gastrointestinal obstruction secondary to aortoduodenal syndrome owing to a noninflammatory abdominal aortic aneurysm.

LENUS (Irish Health Repository)

Cahill, Kevin

2012-01-31

Aortoduodenal syndrome is a rare complication of an abdominal aortic aneurysm wherein the aneurysm sac obstructs the patient\\'s duodenum. It presents with the symptoms of an upper gastrointestinal tract obstruction and requires surgical intervention to relieve it. Previously, gastric bypass surgery was advocated, but now aortic replacement is the mainstay of treatment. We report a case of a 67-year-old woman whose aortoduodenal syndrome was successfully managed and review the literature on this topic.

Obstructive sleep apnea syndrome obstructive sleep apnea syndrome is associated with symptoms including habitual snoring, witness apnea and excessive daytime sleepiness. Also obstructive sleep apnea syndrome is related to some occupations which are needed attention for work accident. We aimed to determine the prevalence of snoring, witnessed apnea and excessive daytime sleepiness in coal workers and healthy adults in Zonguldak city center, and also evaluate the differences between these groups. This study consisted of 423 underground coal workers and 355 individuals living in centre of Zonguldak. Study and comparison group were chosen by nonstratified randomized sampling method. Data were collected by a questionnaire that included information regarding snoring, witnessed apnea and excessive daytime sleepiness. Mean age was 43.3 ± 6.05 years in miners and 44.3 ± 11.8 years in comparison group. In miners, snoring frequency was determined as 42.6%, witnessed apneas were 4.0%, and daytime sleepiness were 4.7%. In comparison group, these symptoms were 38.6%, 4.8% and 2.8% respectively. There were no statistical differences between coal workers and comparison group in these symptoms. Also snoring prevalence was higher in smoker miners. We found that major symptoms of obstructive sleep apnea syndrome in coal workers are similar to general population in Zonguldak. Further studies that constucted higher populations and with polysomnography are needed to evaluate these findings.

Full Text Available Since obstructive sleep apnea-hypopnea syndrome (OSAHS is a multisystemic disease, it also affects the endocrine system. Normal production of hormones can be influenced by the presence of intermittent hypoxia, inflammation, and oxidative stress; for example, subjects with obesity and OSAHS have much higher leptin levels than obese subjects without OSAHS. This article discusses the relationship between sleep apnea and obesity, metabolic syndrome (MS, diabetes mellitus type 2 (DM2, neuroendocrine disorders and osteoporosis.

The Mirizzi syndromes involves obstruction of the common hepatic duct by a gallstone impacted in the bladder neck or in the cystic duct. It is accompanied by and inflammatory reaction that usually produces a biliary fistula. On rare occasions, this disorder can lead to obstructive jaundice. We reviewed nine cases of Mirizzi syndrome, comparing the findings according to different imaging techniques. All the patients underwent ultrasound study, three were assessed by computerized tomography (CT) and three by transhepatic cholangiography (THC). In eight patients, the diagnosis was confirmed intraoperatively: the remaining patient was diagnosed on the basis of the clinical evidence of obstructive jaundice, ultrasound and THC. In eight patients, ultrasound disclosed dilation of the intrahepatic bile duct. Scleroatrophic bladder with a large stone in the infundibular zone was observed in five cases, and numerous small calculi were found in the remaining four patients, two of whom presented thickening of the bladder walls: the walls were normal in the other two. Pneumobilia was observed one case. CT revealed dilation of the intrahepatic bile duct in all three cases in which it was performed. A cavity containing a calculus was observed in one case and pneumobilia in another. THC disclosed dilation of the intrahepatic bile duct and a lateral filling defect in the common hepatic duct in all three patients in whom it was performed. Two patients were found to have cholecystocholedochal fistulas. The Mirizzi syndrome should be suspected when a scleroatrophic gallbladder or gallstones compress the common hepatic duct, causing proximal, but not distal, bile duct dilation. In these case, THC should be carried out to confirm the diagnosis and determine whether or not a fistula is present since the surgical treatment varies depending on the existence of fistulas and their location.

This coexistence is known as overlap syndrome and is the result of chance rather than a pathophysiological link. Although there are claims of a very high incidence of OSAS in COPD patients, recent studies report that it is similar to the general population. Overlap patients present sleep-disordered breathing associated to upper and lower airway obstruction and a reduction in respiratory drive. These patients present unique characteristics, which set them apart from either COPD or OSAS patients. COPD and OSAS are independent risk factors for cardiovascular events and their coexistence in overlap syndrome probably increases this risk. The mechanisms underlying cardiovascular risk are still unclear, but may involve systemic inflammation, endothelial dysfunction, and tonic elevation of sympathetic neural activity. The treatment of choice for overlap syndrome in stable patients is CPAP with supplemental oxygen for correction of upper airway obstructive episodes and hypoxemia during sleep.Keywords: chronic obstructive pulmonary disease, obstructive sleep apnea syndrome, overlap syndrome, sleep, cardiovascular disease

Purpose: Ogilvie's syndrome is defined as an acute pseudo-obstruction of the colon, characterized by the signs, symptoms and radiological pattern of a large-bowel obstruction, but without a detectable organic cause. The aetiology of Ogilvie's syndrome appears to be multifactorial, with a series of possibly interacting pathogenic noxae all resulting in colon inactivity. Our study reports on six cases of Ogilvie's syndrome diagnosed and treated between 1997 and 2002. Materials and methods: From October 1997 to September 2002 we studied six patients affected by pseudo-obstruction of the colon. The pseudo-obstruction was recurrent in two cases. Acute dilatation of the colon without radiologically-detectable organic obstruction was the inclusion criterion for the study. Results: Plain abdominal radiography revealed colon dilatation that extended to the splenic flexure in three patients, to the hepatic flexure in two patients, and confined to the transverse colon in one patient. None of the patients showed air-fluid levels of the small intestine. Conclusion: The most relevant clinical finding in Ogilvie's syndrome is abdominal distension, which arises suddenly, has a progressive course and reaches massive levels. The first-line diagnostic investigation is plain abdominal radiography which shows extreme colon dilatation without air-fluid levels of the small intestine. In three of our patients, conservative therapy alone was able to restore normal conditions within five days; two patients required decompressive colonoscopy, and one patient died from cardio-circulatory arrest after 48 hours [it

Phenotype of asthma-chronic obstructive pulmonary disease overlap syndrome.

Rhee, Chin Kook

2015-07-01

Many patients with asthma or chronic obstructive pulmonary disease (COPD) have overlapping characteristics of both diseases. By spirometric definition, patients with both fixed airflow obstruction (AO) and bronchodilator reversibility or fixed AO and bronchial hyperresponsiveness can be considered to have asthma-COPD overlap syndrome (ACOS). However, patients regarded to have ACOS by spirometric criteria alone are heterogeneous and can be classified by phenotype. Eosinophilic inflammation, a history of allergic disease, and smoke exposure are important components in the classification of ACOS. Each phenotype has a different underlying pathophysiology, set of characteristics, and prognosis. Medical treatment for ACOS should be tailored according to phenotype. A narrower definition of ACOS that includes both spirometric and clinical criteria is needed.

2017-08-01

Full Text Available Obstructive sleep apnea-hypopnea syndrome (OSAHS is characterized by the partial obstruction or total collapse of the upper airway in an intermittent and repetitive manner; in this scenario, surgical management was initially regarded as an alternative for treating this pathology. Nowadays, surgery is highly recognized because it improves tolerance and adaptation to positive pressure therapy; it remains as the first line of treatment, although high rates of effectiveness are not achieved. The first step before considering any surgical procedure is an adequate topographic diagnosis; therefore, a nasofibrolaryngoscopy should always be performed to identify the obstruction site(s. It is known that 75% of patients have obstructions at multiple levels, so correcting OSAHS by up to 95% is possible when the approach considers all the levels. Current procedures include nasal surgery, soft palate, tonsils, tongue base, hypoglossal nerve stimulator and facial skeletal procedures, as well as adjuvant procedures that include radiofrequency and palate implants.

Knowing the risk factors associated to sleep disorders allows to develop therapeutic measures focused on their origin. Modifiable factors such as overweight/obesity, smoking and consumption of central nervous system depressants are especially important since prevention of these conditions may have an impact on the prevention of the onset of the obstructive sleep apnea-hypopnea syndrome.

Localizing obstructive sites with dynamic MRI and consequentially proper therapy selection for obstructive sleep apnea/hypopnea syndrome

International Nuclear Information System (INIS)

Oda, Makoto

2004-01-01

At present, selection of therapies for obstructive sleep apnea/hypopnea syndrome (OSAHS) relies on the localizing the obstructive sites and determination of its severity by polysomnography (PSG). Many methods have been applied to localize the obstructive sites. We attempted to evaluate the morphology of upper airway during sleep with dynamic MRI, and assessed the severity of OSAHS and results of therapies in groups classified by the patterns of obstructive sites. A categorizing system was set up, by which the obstructive sites were reviewed on axial and sagittal sections and accordingly classified into four patterns: front-to-back pattern, left-to-right pattern, circular pattern and epiglottis pattern. Comparison of apnea/hypopnea index (AHI), lowest SpO2 and BMI was performed between the different patterns. The results showed that the left-to-right pattern and circular pattern had a higher AHI and lower lowest SpO2, and more cases of obesity with higher BMI were found in these two groups. We also evaluated the results of different therapies for different obstructive site patterns. Radiofrequency coblation of soft palate was found to be effective for the front-to-back pattern. Improvement was found in 67% of all the cases that received uvulopalatopharyngoplasty (UPPP), while a significant postoperative improvement of AHI was confirmed in left-to-right pattern and circular pattern groups. No significant difference in the results was found between different obstructive sites or patterns when nasal continuous positive airway pressure (n-CPAP) was applied alone. Being completely free from CPAP (completed treatment with improvement of symptoms) was achieved in 71.4% of all the cases and 85.7% in the left-to-right pattern group who received UPPP. We conclude that an optimal treatment results could be achieved by selecting the therapies based on the severity of OSAHS and result of localizing the obstructive sites by dynamic MRI. (author)

Congenital high airway obstruction syndrome (CHAOS) is a rare life-threatening condition characterised by complete or near-complete developmental obstruction of the foetal airway. Although antenatal imaging findings have been described, the postmortem MRI findings have not been reported. To present postmortem MRI features of CHAOS. We retrospectively reviewed our hospital pathology and imaging databases for cases of CHAOS over a 2-year period. We identified two cases of CHAOS. In both cases, postmortem plain radiographs demonstrated gross abdominal distension with distortion and splaying of the rib cage. Both foetuses had characteristic postmortem MRI findings including large-volume fluid-filled lungs on T2-weighted imaging, diaphragmatic eversion, fluid-filled airway dilatation below the level of obstruction, centrally positioned and compressed heart, and massive ascites. One foetus had an associated limb abnormality. Postmortem MRI in foetuses suspected of having CHAOS allows confirmation of the diagnosis, determination of the anatomical level of the atresia or stenosis, and identification of associated abnormalities without the need for invasive autopsy.

Full Text Available CONTEXT: The correlation between vaginal delivery, age and pelvic floor dysfunctions involving obstructed defecation is still a matter of controversy. OBJECTIVES: To determine the influence of age, mode of delivery and parity on the prevalence of posterior pelvic floor dysfunctions in women with obstructed defecation syndrome. METHODS: Four hundred sixty-nine females with obstructed defecation syndrome were retrospectively evaluated using dynamic 3D ultrasonography to quantify posterior pelvic floor dysfunctions (rectocele grade II or III, rectal intussusception, paradoxical contraction/non-relaxation of the puborectalis and entero/ sigmoidocele grade III. In addition, sphincter damage was evaluated. Patients were grouped according to age (50y and stratified by mode of delivery and parity: group I (50y: 251 patients, 60 nulliparous, 148 vaginal delivery and 43 only caesarean section. Additionally, patients were stratified by number of vaginal deliveries: 0 - nulliparous (n = 135, 1 - vaginal (n = 46, >1 - vaginal (n = 166. RESULTS: Rectocele grade II or III, intussusception, rectocele + intussusception and sphincter damage were more prevalent in Group II (P = 0.0432; P = 0.0028; P = 0.0178; P = 0.0001. The stratified groups (nulliparous, vaginal delivery and cesarean did not differ significantly with regard to rectocele, intussusception or anismus in each age group. Entero/sigmoidocele was more prevalent in the vaginal group 50y. No correlation was found between rectocele and the number of vaginal deliveries. CONCLUSION: Higher age (>50 years was shown to influence the prevalence of significant rectocele, intussusception and sphincter damage in women. However, delivery mode and parity were not correlated with the prevalence of rectocele, intussusception and anismus in women with obstructed defecation.

This study aimed to compare the efficiency of the STOP-BANG and Berlin Obstructive Sleep Apnoea Syndrome questionnaires for evaluating potential respiratory complications during the perioperative period. Questionnaires that are used to determine obstructive sleep apnoea risk are not widely used for surgical patients. Among the questionnaires that are commonly used for obstructive sleep apnoea screening, it remains unclear whether the STOP-BANG or Berlin Obstructive Sleep Apnoea Syndrome questionnaire is more effective in terms of ease of use, usage period and diagnosis of surgical patients with obstructive sleep apnoea risk. This study was designed as a descriptive and prospective study. The study included 126 patients over 18 years of age who were American Society of Anesthesiologists classification class I-II and underwent laparoscopic cholecystectomy. To determine the potential obstructive sleep apnoea syndrome risk, the STOP-BANG and Berlin questionnaires were administered. Respiratory complications were then observed during the perioperative period. During intubation and extubation, we observed statistically significant differences in difficult intubation, difficult facemask ventilation and desaturation frequency between the high- and low-risk groups for obstructive sleep apnoea syndrome, as determined by the STOP-BANG questionnaire. During extubation, statistically significant differences in coughing, breath-holding and desaturation frequency were observed between the high-risk and low-risk groups, according to the Berlin questionnaire. In the post-anaesthesia care unit, both questionnaires found statistically significant differences between the low- and high-risk groups. Obstructive sleep apnoea syndrome screening questionnaires administered during the preoperative period are useful for predicting perioperative respiratory complications. It may be most useful to administer the STOP-BANG questionnaire as the initial evaluation. Questionnaires may be used to

Membranous obstruction of the hepatic inferior vena cava (MOVC) is one of the common causes of Budd-Chiari syndrome. The aim of this study is to ascertain and compare the characteristic sonographic and CT findings of Budd-Chiari syndrome caused by MOVC. We studied 10 patients of Budd-Chiari syndrome caused by MOVC thorough sonography and CT. MOVC was confirmed by operation and/or inferior vena cavography. The cases included 9 men and one woman. With sonography, IVC obstruction was diagnosed in 9 cases. The cause of IVC obstruction was web in 5 cases and fibrous cord in 3 cases. The cause was unspecified in one case. Obliteration of the hepatic veins and intrahepatic collateral vessels were delineated in 9 cases. With color doppler sonography, the directions of blood flow of the hepatic veins through the intervenous communication were fairly well demonstrated in all 5 cases. With CT, IVC obstruction was diagnosed in 7 cases. The obliteration of the hepatic segment of the IVC were segmental in 6 cases and diffuse in one case. CT demonstrated communicating vessels between the hepatic veins in 3 cases. Furthermore, systemic collateral vessels (azygos and hemiazygos veins, veins along the abdominal wall, and internal mammary veins) were demonstrated in all cases. Liver cirrhosis was combined in all cases and hepatoma developed in 4 cases. Sonography is useful to detect the MOVC and to demonstrate hepatic venous obstruction and intrahepatic collateral vessels. Color doppler sonography is easily performed to show the direction of the blood flow through interconnecting vessels. CT shows the obliterated segment of the IVC clearly and multiple prominent systemic collaterals. In conclusion, Budd-Chiari syndrome caused by MOVC is accurately diagnosed by combined color doppler sonography and CT

To investigate the symptoms most frequently found in children with a polysomnographic diagnosis of obstructive sleep apnea-hypopnea syndrome (OSAHS). We evaluated 38 children consecutively referred to the sleep laboratory with suspicion of OSAHS between June of 2003 and December of 2004. The patients were submitted to a pre-sleep questionnaire and to polysomnography. The mean age was 7.8 +/- 4 years (range, 2-15 years), and 50% of the children were male. Children without apnea accounted for 7.9% of the sample. The obstructive sleep apnea observed in the remainder was mild in 42.1%, moderate in 28.9% and severe in 22.1%. Severe cases of apnea were most common among children under the age of six (pre-school age). In children with OSAHS, the most common symptoms were snoring and nasal obstruction, which were observed in 74.3 and 72.7% of the children, respectively. Excessive sleepiness and bruxism were seen in 29.4 and 34.3%, respectively, and reflux disease was seen in only 3.1%. Restless legs and difficulty in falling asleep were identified in 65 and 33%, respectively. All of the children diagnosed with severe OSAHS also presented snoring and bruxism. Snoring and nasal obstruction were the most common symptoms found in our sample of children and adolescents with OSAHS. In addition, OSAHS severity was associated with being in the lower age bracket.

Angiographic and hemodynamic evaluation of the mesoatrial shunt in patients with Budd-Chiari syndrome and inferior vena caval obstruction

Obstruction of the inferior vena cava (IVC) is not uncommon in patients with the Budd-Chiari syndrome. The caval obstruction may be due to thrombus or compression by an enlarged caudate lobe. Conventional portosystemic shunts are not possible in the presence of an obstructed IVC; the mesoatrial shunt is indicated in these patients. Between 1973 and 1986, the authors studied 13 patients (ten female, three male) with Budd-Chiari syndrome and IVC obstruction in whom mesoatrial shunts were subsequently constructed. Polycythemia rubra vera was the most common predisposing condition. Preoperative evaluation included US, scintigraphy, CT, and angiography (hepatic arteriography, hepatic venography and pressure measurements, inferior vena cavography, arterial portography). Postoperatively shunts were assessed angiographically and hemodynamically, and several patients underwent CT. The shunts were catheterized via a brachial or femoral venous approach, which allowed pressures along the shunt from the superior mesenteric vein to the right atrium to be measured. The mesoatrial shunt is a relatively new procedure which is indicated in patients with the Budd-Chiari syndrome complicated by IVC obstruction. Shunt patency may be demonstrated arteriographically or with CT, but hemodynamic evaluation with measurement of pressure gradients is required to assess shunt function

Anorectal manometry (ARCM) provides valuable information in children with chronic constipation and fecal incontinence but may not be tolerated in the awake child. This study aimed to evaluate the effect of ketamine anesthesia on the assessment of anorectal function by manometry and to evaluate defecation dynamics and anal sphincter resting pressure in the context of pathophysiology of chronic functional (idiopathic) constipation and soiling in children. This was a prospective study of children who were investigated for symptoms of chronic constipation and soiling between April 2001 and April 2004. We studied 52 consecutive children who had awake ARCM, biofeedback training and endosonography (awake group) and 64 children who had ketamine anesthesia for ARCM and endosonography (ketamine group). We age matched 31 children who had awake anorectal studies with 27 who had ketamine anesthesia. The children in awake and ketamine groups were comparable for age, duration of bowel symptoms and duration of laxative treatments. ARCM profile was comparable between the awake and the ketamine groups with regard to anal sphincter resting pressure, rectal capacity, amplitude of rectal contractions, frequency of rectal and IAS contractions and functional length of anal canal. Of 52 children who had awake ARCM, dyssynergia of the EAS muscles was observed in 22 (42%) and median squeeze pressure was 87mm Hg (range 25-134). The anal sphincter resting pressure was non-obstructive and comparable to healthy normal children. Rectoanal inhibitory reflex was seen in all children excluding diagnosis of Hirschsprung disease. Ketamine anesthesia does not affect quantitative or qualitative measurements of autonomic anorectal function and can be used reliably in children who will not tolerate the manometry while awake. Paradoxical contraction of the EAS can only be evaluated in the awake children and should be investigated further as the underlying cause of obstructive defecation in patients with

Sergio Garbarino

Full Text Available OBJECTIVE: To determine the frequency of obstructive sleep apnea syndrome (OSAS, metabolic syndrome and common mental disorders in the working population of 11 small enterprises and the feasibility of a program of action for health. METHOD: The clinical risk of OSAS, the prevalence of metabolic syndrome, and the level of psychological disorders were assessed during routine medical examination at the workplace in 2012. The response to medical advice was assessed in 2013. RESULTS: 12.3% of the workers were suspected of being affected by OSAS. One or more components of metabolic syndrome were present in 24.5% of cases. OSAS in "healthy" workers was significantly associated with the presence of one or more components of metabolic syndrome (OR = 3.83; 95%CI 1.45-10.13 and with a psychological disorders score in the highest quartile (OR = 4.67; 95%CI = 1.72-12.64. Workers with suspected OSAS were reluctant to follow advice about undergoing further tests under the NHS. However, in some cases, confirmation of the OSAS diagnosis and subsequent treatment led to an improvement in metabolic condition. CONCLUSION: Although participation in treatment was limited, anecdotal cases support the idea that prevention of obstructive sleep apnea in the workplace might be useful for workers' health.

Fifteen subjects presenting with intractable constipation due to obstructive defecation, mean (SEM) duration 8.8 (1.8) years, had the inappropriate contraction and electromyographic changes in the pelvic floor muscles and external and sphincter typical of this condition. An electromyographically derived index was used to grade its severity. A self applied biofeedback device was used to allow electromyographic recording of the abnormal external anal sphincter. The subjects were encouraged to reduce the abnormal electromyographic activity on straining after instruction and training. The procedure was intended as a relearning process in which the non-relaxing activity of the pelvic floor was gradually suppressed. Biofeedback training was maintained on a domiciliary basis for a mean time of 3.1 weeks and resulted in a significant reduction in the anismus index (mean (SEM) 69.9 (7.8)% before biofeedback, mean 14 (3.9)% after biofeedback, p less than 0.01). There was an associated reduction in the time spent straining at stool and in the difficulty of defecation and an increased frequency of defecation. Defecatory video proctograms in six subjects showed improvements in the anorectal angle during straining and evacuation. The clinical benefit to the patients persisted after a mean follow up of 6.2 months.

The aim of the study was to determine the prevalence of stressful life events including (sexual) abuse in children with functional defecation disorders by performing a systematic review. We searched MEDLINE, EMBASE, and PsycINFO for cohort, case-control and cross-sectional studies investigating the prevalence of stressful life events, including (sexual) abuse in children with functional defecation disorders. The search yielded 946 articles, of which 8 were included with data from 654 children with functional constipation and 1931 children with (constipation-associated) fecal incontinence (FI). Overall, children with functional defecation disorders had been significantly more exposed to stressful life events than healthy children, with prevalence rates ranging from 1.6% to 90.9%. Being bullied, being a relational victim, interruption of toilet training, punishment by parents during toilet training, and hospitalization were significantly related to FI, whereas separation from the best friend, failure in an examination, severe illness in a close family member, loss of job by a parent, frequent punishment, and living in a war-affected area were significantly related to constipation. Only 1 study measured the prevalence of child abuse, which reported a significantly higher prevalence of child (sexual) abuse in children with FI compared with controls. The prevalence of stressful life events, including (sexual) abuse is significantly higher in children with functional defecation disorders compared with healthy children. To gain more insight into the true prevalence of child (sexual) abuse in children with functional defecation disorders, more studies are clearly needed.

This study was designed to clarify the mechanism of disordered defecation after low anterior resection (LAR). Twenty four patients were divided into two groups, the poor motility group (Group I), including 12 subjects who defecated over four times per day, and the good motility group (Group II), including 12 subjects who defecated under three times per day. At first, a polyethylene-tube was inserted into the cecum using a colonoscope and a guide wire. 37 MBq 99m TcDTPA in 50 ml of tepid saline containing 5 mg of bisacodyl was infused into the cecum through the tube. Transit time and expulsion ratio from the rectum (ERr) were studied. The average times of propelling RI-solution from the transverse colon to the descending colon, from the descending colon to the rectum, and from the rectum to defecation were 37.5 seconds and 163.7 seconds, 48.7 and 293.5, 47.7 and 215.5, respectively in Group I and Group II. ERr was 84.3% in Group I and 94.5% in Group II. There are significant differences between these two groups. Colonic transit time in Group I was shorter than that in Group II, and ERr in Group I was less than that in Group II. These results suggest that the disordered defecation after LAR may be partly caused by poor colonic motility and dysfunction of the neorectum. (author)

Full Text Available Insulin resistance is often associated with obstructive sleep apnoea syndrome (OSAS and could contribute to cardiovascular risk in OSAS. Sleep loss and intermittent hypoxia could contribute to the pathogenesis of the metabolic alterations associated with obesity, a common feature of OSAS. The biology of the adipocyte is being increasingly studied, and it has been found that hypoxia negatively affects adipocyte function. In November 2007, the European Respiratory Society and two EU COST Actions (Cardiovascular risk in OSAS (B26 and Adipose tissue and the metabolic syndrome (BM0602, held a Research Seminar in Düsseldorf, Germany, to discuss the following: 1 the effects of hypoxia on glucose metabolism and adipocyte function; 2 the role of inflammatory activation in OSAS and obesity; 3 the alarming rates of obesity and OSAS in children; 4 the harmful effects of the metabolic syndrome in OSAS; 5 the effects of OSAS treatment on metabolic variables; and 6 the relationship between daytime sleepiness and hormonal and inflammatory responses. Insulin resistance in skeletal muscle, the role of the endocannabinoid system and novel pharmacological approaches to treat insulin resistance were also discussed. As obesity and hypoxia could be the basic links between OSAS and adipocyte dysfunction, further research is needed to translate these new data into clinical practice.

The correlation between vaginal delivery, age and pelvic floor dysfunctions involving obstructed defecation is still a matter of controversy. To determine the influence of age, mode of delivery and parity on the prevalence of posterior pelvic floor dysfunctions in women with obstructed defecation syndrome. Four hundred sixty-nine females with obstructed defecation syndrome were retrospectively evaluated using dynamic 3D ultrasonography to quantify posterior pelvic floor dysfunctions (rectocele grade II or III, rectal intussusception, paradoxical contraction/non-relaxation of the puborectalis and entero/ sigmoidocele grade III). In addition, sphincter damage was evaluated. Patients were grouped according to age (≤50y x >50y) and stratified by mode of delivery and parity: group I (≤50y): 218 patients, 75 nulliparous, 64 vaginal delivery and 79 only cesarean section and group II (>50y): 251 patients, 60 nulliparous, 148 vaginal delivery and 43 only caesarean section. Additionally, patients were stratified by number of vaginal deliveries: 0 - nulliparous (n = 135), 1 - vaginal (n = 46), >1 - vaginal (n = 166). Rectocele grade II or III, intussusception, rectocele + intussusception and sphincter damage were more prevalent in Group II (P = 0.0432; P = 0.0028; P = 0.0178; P = 0.0001). The stratified groups (nulliparous, vaginal delivery and cesarean) did not differ significantly with regard to rectocele, intussusception or anismus in each age group. Entero/sigmoidocele was more prevalent in the vaginal group 50y. No correlation was found between rectocele and the number of vaginal deliveries. Higher age (>50 years) was shown to influence the prevalence of significant rectocele, intussusception and sphincter damage in women. However, delivery mode and parity were not correlated with the prevalence of rectocele, intussusception and anismus in women with obstructed defecation.

Budd-Chiari syndrome (BCS) is a rare clinical entity characterized by post-sinusoidal portal hypertension caused by the obstruction to the hepatic vein outflow. The diagnosis is suggested by hepatic scintigraphy and is usually confirmed by hepatic venography, inferior vena cavography and biopsy. The scintigraphic finding of BCS caused by the obstruction of main hepatic vein has been reported to consist typically of hypertrophy of the caudate lobe with increased radionuclide accumulation. Such a typical finding has been accounted for by the fact that the venous outflow from the caudate lobe is preserved when the main hepatic vein is obstructed. But usually, the hepatic venous outflow from the caudate lobe is also obstructed in BCS due to inferior vena caval obstruction. So hepatic scintigraphic findings of BCS due to inferior vena caval obstruction show different findings as compared with the BCS due to hepatic vein obstruction. We evaluate the hepatic scintigrams of the 13 cases of BCS due to inferior vena caval obstruction and review the literatures. The results are as follows: 1) We cannot observe the caudate lobe hypertrophy with increased uptake, which is known as a classic finding in BCS due to hepatic vein obstruction. 2) The most prominent hepatic scintigraphic findings of BCS are nonhomogenous uptake in the liver with extrahepatic uptake in the all cases. 3) We can see cold areas at the superior aspect of right hepatic lobe in 7 cases (54%). This is a useful finding suggesting BCS due to inferior vena caval obstruction.

Hillarp, B.; Rosen, I.; Wickstroem, O.; Malmoe Allmaenna Sjukhus

1991-01-01

Percutaneous submental electrical stimulation during sleep may be a new therapeutic method for patients with obstructive sleep apnea syndrome (OSAS). Electrical stimulation to the submental region during obstructive apnea is reported to break the apnea without arousal and to diminish apneic index, time spent in apnea, and oxygen desaturation. The mode of breaking the apnea by electrical stimulation has not yet been shown. However, genioglossus is supposed to be the muscle responsible for breaking the apnea by forward movement of the tongue. To visualize the effect of submental electrical stimulation, one patient with severe OSAS has been examined with videoradiography. Submental electrical stimulation evoked an immediate complex muscle activity in the tongue, palate, and hyoid bone. This was followed by a forward movement of the tongue which consistently broke obstructive apnea without apparent arousal. Time spent in apnea was diminished but intervals between apnea were not affected. (orig.)

To describe clinicofunctional features of essential and pulmogenic hypertension in chronic bronchoobstructive syndrome, 24-h profile of arterial pressure (AP), intracardiac hemodynamics and to propose differential diagnostic criteria for these hypertension forms. 24-h monitoring of arterial pressure (MAP), cardiohemodynamics, external respiration function (ERF) and blood gases examinations were made in 100 hypertensive subjects with chronic obstructive bronchitis and bronchial asthma. Significant differences were found between the groups of essential and pulmogenic hypertension by major values of MAP, echo-CG and ERF. Early disturbances in diastolic function of both the ventricles in essential and pulmonary hypertension in chronic bronchial obstruction arise long before clinical, x-ray and ECG signs of chronic pulmonary heart. The findings enable formulation of criteria of differential diagnosis of essential and pulmogenic hypertension and identify the latter as an independent nosological entity.

Full Text Available Obstructive sleep apnoea (OSA is a highly prevalent disorder associated with complications such as arterial hypertension, cardiovascular diseases and traffic accidents. The resources allocated for OSA are insufficient and OSA is a significant public health problem. Portable recording devices have been developed for the detection of OSA syndrome and have proved capable of providing an equivalent diagnosis to in-laboratory polysomnography (PSG, at least in patients with a high pre-test probability of OSA syndrome. PSG becomes important in patients who have symptoms and certain comorbidities such as chronic obstructive pulmonary disease or stroke, as well as in patients with a clinical history suggesting a different sleep disorder. Continuous positive airway pressure is the most effective treatment in OSA. Ambulatory monitoring of the therapeutic modalities has been evaluated to enhance the care process and reduce costs compared to the conventional approach, without sacrificing efficiency. This review evaluates the role of portable monitoring devices in the diagnostic process of OSA and the search for alternative strategies based on ambulatory management protocols.

Ogilvie's syndrome (OS), a massive dilation of the colon in the absence of mechanical obstruction, is a rare postsurgical complication. The high mortality rate (normally 15 - 31% and upto 45% after caecal perforation) explains the seriousness of this clinical situation. Early diagnosis is made by plain abdominal X-ray and CT abdomen. Conservative treatment is usually effective and surgery should be reserved for complicated cases or refractory to conservative treatment. We report a case of 25 years primigravida who developed OS, 24 hours after cesarean section, which was treated by conservative methods. (author)

Identification of risk factors for obstructive sleep apnea (OSA) is important to enable comprehensive intervention to reduce OSA-related cardiovascular disease (CVD). The metabolic syndrome outcome study (MetSO) provides a unique opportunity to address these factors. This study investigated risk of OSA among blacks with metabolic syndrome. The present study utilized data from MetSO, an NIH-funded cohort study of blacks with metabolic syndrome. A total of 1,035 patients provided data for the analysis. These included sociodemographic factors, health risks, and medical history. Physician-diagnosed conditions were obtained using an electronic medical record system (Allscripts, Sunrise Enterprise). Patients were diagnosed with metabolic syndrome using criteria articulated in the joint interim statement for harmonizing the metabolic syndrome. Patients with a score ≥6 on the Apnea Risk Evaluation System (ARES) questionnaire were considered at risk for OSA. Obesity is defined by body mass index (BMI ≥ 30 kg/m 2 ). Of the 1,035 patients screened in the MetSO cohort, 48.9% were at high risk for OSA. Using multivariate-adjusted logistic regression analysis, we observed that obesity was the strongest predictor of OSA risk (OR=1.59, 95%CI=1.24-2.04, pmetabolic syndrome.

In sub-Saharan Africa, it is estimated that 215 million people continue to engage in open defecation. This practice facilitates the transmission of diarrheal diseases - one of the leading causes of mortality in children under 5 in sub-Saharan Africa. The main purpose of this study is to: estimate changes in open defecation prevalence between 2005 and 2010 across countries in sub-Saharan Africa; examine the association between national level indices and changes in open defecation prevalence; and assess how many countries can achieve 'open defecation free status' by 2015. After applying selection criteria, this study analyzed country-level data for 34 sub-Saharan African countries. Seven country-level indices were collected: 1) presence of a national sanitation policy; 2) budget line for sanitation; 3) budget allocated to sanitation; 4) annual per capita GDP; 5) GDP growth; 6) implementation of total sanitation approaches; and 7) per capita aid disbursement for water supply and sanitation. The relationships between these country-level indices and the change in open defecation from 2005 to 2010 were investigated using Wilcoxon Signed-Rank test and Spearman's rank correlation test. Only 3 countries (i.e. Ethiopia, Angola and Sao Tome and Principe) decreased open defecation by 10% or more between 2005 and 2010. No significant associations were observed between the change in open defecation prevalence and all of national level indices except per capita aid disbursement. Per capita aid disbursement for water and sanitation was positively associated with a reduction in open defecation (p-value = 0.02) for a subset of 29 low-income countries from 2005 to 2010. Only one country in our analysis, Angola, is on track to end open defecation by 2015 based on their performance between 2000 and 2010. Most of the national level indices, including a country's economic status, were not associated with the change in the open defecation prevalence. Based on current trends, the goal

Background: Constipation and encopresis frequently cause problems with respect to emotional wellbeing, and social and family life. Instruments to measure Health Related Quality of Life (HRQoL) in these disorders are not available. Methods: A disease specific HRQoL instrument, the "Defecation Disorder List" (DDL) for children with constipation or functional non-retentive faecal soiling (FNRFS) was developed using accepted guidelines. For each phase of the process, different samples of patients were used. The final phase of development included 27 children. Reliability was assessed in two ways: internal consistency of domains with Cronbach's alpha, and test-retest reliability with intra-class correlation coefficients (ICC). To assess validity, comparable items and domains were correlated with Tacqol, a generic HRQoL instrument for children (TNO-AZL). Results: In the final phase of the development, 27 children completed the instrument. It consisted of 37 items in four domains. The response rate was 96%. Reliability was good for all domains, with Cronbach's alpha values ranging from 0.61 to 0.76. Measures of test-retest stability were good for all four domains with ICCs ranging from 0.82 to 0.92. Validity based on comparison with the Tacqol instrument was moderate. Conclusion: The DDL is promising as a measure of HRQoL in childhood defecation disorders. PMID:15557046

Full Text Available Objective. To investigate the effect of bronchial obstruction syndrome on perioperative characteristics in patients undergoing coronary artery bypass grafting (CABG.Methods. Body plethysmography and spiroergometry at rest were used to study respiratory function and consumption of O2. To evaluate the effectiveness of pulmonary ventilation, the oxygen utilization coefficient of (O2CU was calculated in 178 patients prior to scheduled surgery. The relationship of external ventilation parameters and perioperative clinical characteristics was analyzed. Results. A bronchial obstruction syndrome was detected in 30 (16.9% patients, with 21 (11.2% of them having no chronic obstructive pulmonary disease diagnosis. 4 patients (2.3% with obstructive pulmonary disease had no bronchial obstruction. Thus, chronic obstructive pulmonary disease was misdiagnosed in 13.5% cases. In patients undergoing isolated CABG, negative relationship was revealed between the Tiffno index and hospital stay (regression coefficient –6.9, 95%, confidence interval –14.4… 0.6; p = 0.07. In patients operated with the myocardium stabilized, bimammary grafting tended to increase hospital stay by an average of 4.3 days (95% CI 1.5–7.1; p=0.003. The majority of patients had a low O2CU. O2CU lower than 16.2 ml/l is associated with an increased risk of postoperative atrial fibrillation (AF in the postoperative period (OR 2.96; 95% CI 1.01–9.83; p = 0.04. No significant associations were observed between the degree of bronchial obstruction and the number of perioperative complications. Conclusion. The degree of bronchial obstruction could be positively associated with the length of hospital stay. A critically low level of O2CU is explained by an increased risk of postoperative AF. Further research might result in the identification of predictors for respiratory complications and long-term mortality in patients after CABG.

Surgical treatment of a Pattern I Obstructive Sleep Apnea Syndrome individual - clinical case report

Directory of Open Access Journals (Sweden)

Christiane Cavalcante Feitoza

Full Text Available Obstructive Sleep Apnea Syndrome (OSA is a multifactorial disease that highly alters a persons quality of life. It is characterized by the repeated interruption of breathing during sleep, due to an obstruction or the collapse of the upper airways. Since it is a multifactorial etiological disorder, it requires a thorough diagnosis and treatment with an interdisciplinary team, which comprises several professionals such as a surgical dentist, phonoaudiologist, otorhinolaryngologist, sleep doctor, neurologist and physiotherapist. The diagnosis and the degree of severity of the syndrome is determined through a polysomnography examination. After that, the best form of treatment is devised depending on the gravity of the case. In cases of moderate to severe apnea, invasive treatment through surgical procedures such as maxillomandibular advancement remains the preferred option as it increases the posterior air space, reducing and/or eliminating the obstruction. Thus, improving the patients respiratory function and, consequently, his quality of life as it is shown in the clinical case at hand. In which the male patient, facial pattern type I, 41 years of age, diagnosed with moderate OSA (Apnea-Hypopnea Index - AHI of 23.19, decided to have a surgical treatment instead of a conservative one, resulting in the cure of apnea (AHI of 0.3.

The afferent loop syndrome corresponds to an acute or chronic obstruction of the afferent loop following a partial gastrectomy with Billroth II gastro-jejunal anastomosis. We describe the case of a 77-year-old man with history of partial gastrectomy for peptic ulcer disease performed 31 years ago and currently admitted for jaundice and poor general status. MR imaging showed dilatation of biliary and pancreatic ducts and showed a soft tissue mass between the afferent loop and the residual stomach. Endoscopy showed complete obstruction of the afferent loop by a biopsy-proven adenocarcinoma. The patient died of sepsis shortly after endoscopy of septicemia. (authors)

Obstructive sleep apnea in chronic obstructive pulmonary disease patients.

LENUS (Irish Health Repository)

Lee, Ruth

2012-02-01

PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) represent two of the most prevalent chronic respiratory disorders and cardiovascular diseases are major co-morbidities in both. Co-existence of both disorders (overlap syndrome) occurs in 1% of adults and overlap patients have worse nocturnal hypoxemia and hypercapnia than COPD and OSA patients alone. The present review discusses recent data concerning the pathophysiological and clinical significance of the overlap syndrome. RECENT FINDINGS: The severity of obstructive ventilatory impairment and hyperinflation, especially the inspiratory capacity to total lung capacity (TLC) ratio, correlates with the severity of sleep-related breathing disturbances. Early treatment with continuous positive airway pressure (CPAP) improves survival, reduces hospitalization and pulmonary hypertension, and also reduces hypoxemia. Evidence of systemic inflammation and oxidative stress in COPD and sleep apnea provides insight into potential interactions between both disorders that may predispose to cardiovascular disease. Long-term outcome studies of overlap patients currently underway should provide further evidence of the clinical significance of the overlap syndrome. SUMMARY: Studies of overlap syndrome patients at a clinical, physiological and molecular level should provide insight into disease mechanisms and consequences of COPD and sleep apnea, in addition to identifying potential relationships with cardiovascular disease.

Sleep apnea syndrome. Examination of pharyngeal obstruction with high-speed MR and polysomnography

1995-01-01

We attempted to determine the usefulness of high-speed MR imaging for evaluating the severity of sleep apnea syndrome (SAS) by comparing findings of pharyngeal obstruction obtained with high-speed MR with those of all-night polysomnography (PSG). A total of 33 patients with SAS underwent turbo-FLASH MR examination, while awake and after i.v. injection of hydroxyzine hydrochloride. Serial images were examined by cinemode. Pharyngeal findings on MR were divided into single-site obstruction (SO) at the velopharynx, multiple-site obstruction (MO), and no obstruction (NO). PSG findings were analyzed to determine the predominant type of apnea, severity as evaluated by an apnea index (AI), and the lowest SaO 2 value during sleep. Seventy-five percent of the central apnea group had SO, and 70% of the mixed apneas had MO, while only 15% of the obstructed apneas had MO. The percentage of patients with severe SAS (AI of 20% or higher) was 48% for the SO, and 70% for the MO. The lowest SaO 2 value tended to be low in the mixed apnea in the case of PSG, and tended to be low in the MO at MR examination. Analysis of pharyngeal dynamics using high-speed MR may provide some useful information for evaluating the severity of SAS. (orig.)

Full Text Available Abstract Background Apical ballooning syndrome (or Takotsubo cardiomyopathy is a syndrome of transient left ventricular apical ballooning. Although first described in Japanese patients, it is now well reported in the Caucasian population. The syndrome mimicks an acute myocardial infarction but is characterised by the absence of obstructive coronary disease. We describe a serious and poorly understood complication of Takotsubo cardiomyopathy. Case Presentation We present the case of a 65 year-old lady referred to us from a rural hospital where she was treated with thrombolytic therapy for a presumed acute anterior myocardial infarction. Four hours after thrombolysis she developed acute pulmonary oedema and a new systolic murmur. It was presumed she had acute mitral regurgitation secondary to a ruptured papillary muscle, ischaemic dysfunction or an acute ventricular septal defect. Echocardiogram revealed severe mitral regurgitation, left ventricular apical ballooning, and systolic anterior motion of the mitral valve with significant left ventricular outflow tract gradient (60–70 mmHg. Coronary angiography revealed no obstructive coronary lesions. She had an intra-aortic balloon pump inserted with no improvement in her parlous haemodynamic state. We elected to replace her mitral valve to correct the outflow tract gradient and mitral regurgitation. Intra-operatively the mitral valve was mildly myxomatous but there were no structural abnormalities. She had a mechanical mitral valve replacement with a 29 mm St Jude valve. Post-operatively, her left ventricular outflow obstruction resolved and ventricular function returned to normal over the subsequent 10 days. She recovered well. Conclusion This case represents a serious and poorly understood association of Takotsubo cardiomyopathy with acute pulmonary oedema, severe mitral regurgitaton and systolic anterior motion of the mitral valve with significant left ventricular outflow tract obstruction.

Full Text Available We report a case of a 64-year-old lady who developed clinical features of Wernicke-Korsakoff syndrome following a laparotomy for small bowel obstruction. Following the operation she developed paralytic ileus and required total parenteral nutrition for one month. A suspected history of average 40 units of weekly alcohol consumption prior to the operation could not be confirmed and the patient did not show any sign of alcohol dependence. Within a few months of treatment with a daily oral dose of thiamine 200 mgs supplemented by multivitamins the patient showed subjective evidence of improvement in confusion, confabulation, and anterograde amnesia, although objective tests showed residual deficits in many areas of cognitive functioning, including immediate and delayed recall of verbal and non-verbal materials, planning and switching of attention.

We report a case of sinusoidal obstruction syndrome, a typical and life-threatening complication after allogeneic stem-cell transplantation, successfully treated with defibrotide despite massive multiple organ failure. A 64-year-old Caucasian woman underwent allogeneic peripheral blood stem-cell transplantation from her human leukocyte antigen-identical sister against aggressive lymphoplasmocytoid immunocytoma. Seven days later, the patient developed severe sinusoidal obstruction syndrome according to the modified Seattle criteria. We initiated treatment with defibrotide. Despite early treatment, multiple organ failure with kidney failure requiring dialysis and ventilator-dependent lung failure aggravated the clinical course. Furthermore, central nervous dysfunction occurred as well as transfusion refractory thrombocytopenia. As highlighted in our report, defibrotide is the most promising drug in the treatment of the formerly, almost lethal, severe sinusoidal obstruction syndrome to date. This is demonstrated very clearly in our patient. She improved completely, even after renal, cerebral and respiratory failure.

Obstructive sleep apnea syndrome (OSAS) has been shown to be associated to upper airway inflammation. The object of the present study was to establish the presence of bronchial inflammation in OSAS subjects. In 16 subjects affected by OSAS, and in 14 healthy volunteers, airway inflammation was detected by the cellular analysis of the induced sputum. OSAS patients, as compared to control subjects, showed a higher percentage of neutrophils (66.7+/-18.9 vs. 25.8+/-15.6) (Pbronchial inflammation characterized by a significant increase in neutrophils.

The case of a 50 year old male with the Fiessinger-Leroy-Reiter syndrome, ankylosing spondylitis and generalised pustular psoriasis is reported. This condition wax complicated by non-obstructive cardiomyopathy, congestive cardiac failure and first-degree atrioventricular block, the site of which was localised by electrophysiological studies (nodal block with an infrahisian conduction defect). After failure of several therapeutic regimes, a spectacular improvement was obtained with Methotrexate associated with a diuretic; the signs of heart failure regressed and the cardiomyopathy stablised. A parallel improvement was seen in the skin, cardiac and articular lesions and has been maintained with an 18 months follow-up. Left ventricular performance was studied by echocardiography. The mechanism of the beneficial effect of Methotrexate is unclear; this therapeutic trial is to be extended to include other cases of primary cardiomyopathy without obstruction.

Shmelev, E I; Stepanian, I E

1996-01-01

The paper provides the results of a follow-up of 70 patients with active pulmonary tuberculosis in whom the administration of antituberculous drugs induced eosinophilia and bronchial obstructive syndrome. To eliminate the side effects of antituberculous therapy, a plasmapheresis regimen was performed in 44 patients, the remaining patients were given only bronchodilators and antihistamine drugs. Plasmapheresis as a means for correcting drug-induced eosinophilia and bronchial obstructive syndrome was found to be more effective than drug therapy and, in some cases, enabled antituberculous therapy to be continued, without changing a combination of drugs. It is recommended that plasmapheresis should be used in cases of inadequate efficiency of conventional methods for correcting drug intolerance.

The roles of dentistry in obstructive sleep apnea syndrome (OSAS) are mainly: Craniofacial skeletal diagnosis, Treatment by oral appliance, Prevention of craniofacial skeletal problem. We use cephalometrics, CT and MRI to diagnose craniofacial skeleton of the patients and treat the OSAS patient by the oral appliance. We could make the airway of the OSAS patients bigger by the orthodontic treatment and ENT doctor could make the airway of the patient's patency by removing tonsils and adenoids. If the patient has the airway patency, the mandible of the patient could grow naturally in advanced position and have the airway bigger, consequently the patient could avoid OSAS in his future.

Therapeutic approaches to asthma-chronic obstructive pulmonary disease overlap syndromes.

Science.gov (United States)

Barnes, Peter J

2015-09-01

The recognition that there are some patients with features of asthma and chronic obstructive pulmonary disease (COPD) has highlighted the need to develop more specific treatments for these clinical phenotypes. Some patients with COPD have predominantly eosinophilic inflammation and might respond to high doses of inhaled corticosteroids and newly developed specific antieosinophil therapies, including blocking antibodies against IL-5, IL-13, IL-33, and thymic stromal lymphopoietin, as well as oral chemoattractant receptor-homologous molecule expressed on TH2 cells antagonists. Other patients have severe asthma or are asthmatic patients who smoke with features of COPD-induced inflammation and might benefit from treatments targeting neutrophils, including macrolides, CXCR2 antagonists, phosphodiesterase 4 inhibitors, p38 mitogen-activating protein kinase inhibitors, and antibodies against IL-1 and IL-17. Other patients appear to have largely fixed obstruction with little inflammation and might respond to long-acting bronchodilators, including long-acting muscarinic antagonists, to reduce hyperinflation. Highly selected patients with severe asthma might benefit from bronchial thermoplasty. Some patients with overlap syndromes can be conveniently treated with triple fixed-dose combination inhaler therapy with an inhaled corticosteroid, long-acting β2-agonist, and long-acting muscarinic antagonist, several of which are now in development. Corticosteroid resistance is a feature of asthma-COPD overlap syndrome, and understanding the various molecular mechanisms of this resistance has identified novel therapeutic targets and presented the prospect of therapies that can restore corticosteroid responsiveness.

Effect of eliminating open defecation on diarrhoeal morbidity: an ecological study of Nyando and Nambale sub-counties, Kenya

Directory of Open Access Journals (Sweden)

John Njuguna

2016-08-01

Full Text Available Abstract Background Defecating in the open predisposes people to soil transmitted helminthes and diarrhoeal diseases. An estimated 5.6 million Kenyans defecate in the open. Kenya launched a program to eradicate open defecation by 2013 in the rural areas. By end of 2013, only two sub-counties had eliminated open defecation. These are Nambale and Nyando. The study looked at the impact of eradicating open defecation on diarrhea prevalence among children in these two sub-counties. Methods Data on diarrhoea morbidity among children under 5 years was extracted from the Kenya Health Information System for all the sub-counties in Busia and Kisumu counties for 2012, 2013 and 2014 respectively. Prevalence was calculated for each sub-county in Kisumu for comparison with Nyando’s. Prevalence was also calculated for each sub-county in Busia County and compared to that of Nambale sub-county. A Mann–Whitney U Test was done to test the null hypothesis that diarrhoea prevalence was similar in both open defecation and open defecation free sub-counties. Results A Mann–Whitney U Test revealed significant difference in diarrhoeal prevalence of open defecation sub-counties (Md = 18.4, n = 34 and open defecation free sub-counties (Md = 9.8, n = 5, U = 9, z = −3.2, p = .001. Among the two Counties, Nambale had the lowest prevalence. It recorded a decline from 9.8 to 5.7 % across the three years. Prevalence for diarrhoea cases in Nyando declined from 19.1 to 15.2 % across the three years. Nyando initially had the second highest prevalence in Kisumu County and by 2014 it had the lowest prevalence. Conclusions The two sub-counties with open defecation free status had lower prevalence of diarrhoea cases compared to sub-counties which were yet to attain open defecation free status. This suggests that elimination of open defecation may reduce the number of diarrhoea cases.

The asthma-chronic obstructive pulmonary disease overlap syndrome (ACOS): opportunities and challenges.

2015-01-01

Some individuals share characteristics of asthma and chronic obstructive pulmonary disease (COPD). The asthma-COPD overlap syndrome (ACOS) has been defined as symptoms of increased variability of airflow in association with an incompletely reversible airflow obstruction. In this review, we present the latest findings in the diagnosis, characterization and management of ACOS. Around 15-20% of COPD patients may have an ACOS. Patients with ACOS are characterized by increased reversibility of airflow obstruction, eosinophilic bronchial and systemic inflammation, and increased response to inhaled corticosteroids, compared with the remaining patients with COPD. Patients with ACOS have more frequent exacerbations, more wheezing and dyspnoea, but similar cough and sputum production compared with COPD. The relevance of the ACOS is to identify patients with COPD who may have underlying eosinophilic inflammation that responds to inhaled corticosteroids. So far, the previous diagnosis of asthma in a patient with COPD is the more reliable criterion for ACOS. Ongoing studies will clarify if concentrations of blood eosinophils may be useful to identify this subgroup of patients with COPD. If this is the case, the interest of ACOS may shift to that of eosinophilic COPD, which is easier to diagnose and has clear therapeutic implications.

Full Text Available Embora SAOS seja uma patologia comum, é frequentemente subdiagnosticada. Seus sinais e sintomas são, na sua maioria, subjetivos e, portanto, deve haver suspeição diagnóstica quando existir roncos, sonolência diurna, cansaço, desânimo e alteração de humor. Escalas e tabelas com boa sensibilidade, que incluem os sintomas clínicos mais relevantes e dados do exame físico, podem indicar o diagnóstico de SAOS. A confirmação diagnóstica é realizada através de polissonografia, considerada o método padrão ouro.Although obstructive sleep apnea syndrome is a common disease, it often goes undiagnosed. The signs and symptoms of the syndrome are mostly subjective. Therefore, snoring, daytime sleepiness, fatigue, dejection and mood changes should raise the suspicion of obstructive sleep apnea syndrome. Scales and tables that have good sensitivity and include the most relevant clinical symptoms and physical examination results can suggest a diagnosis of obstructive sleep apnea syndrome. The diagnosis is confirmed by polysomnography, which is considered the gold standard method.

Evidence that central pathways that mediate defecation utilize ghrelin receptors but do not require endogenous ghrelin.

In laboratory animals and in human, centrally penetrant ghrelin receptor agonists, given systemically or orally, cause defecation. Animal studies show that the effect is due to activation of ghrelin receptors in the spinal lumbosacral defecation centers. However, it is not known whether there is a physiological role of ghrelin or the ghrelin receptor in the control of defecation. Using immunohistochemistry and immunoassay, we detected and measured ghrelin in the stomach, but were unable to detect ghrelin by either method in the lumbosacral spinal cord, or other regions of the CNS In rats in which the thoracic spinal cord was transected 5 weeks before, the effects of a ghrelin agonist on colorectal propulsion were significantly enhanced, but defecation caused by water avoidance stress (WAS) was reduced. In knockout rats that expressed no ghrelin and in wild-type rats, WAS-induced defecation was reduced by a ghrelin receptor antagonist, to similar extents. We conclude that the ghrelin receptors of the lumbosacral defecation centers have a physiological role in the control of defecation, but that their role is not dependent on ghrelin. This implies that a transmitter other than ghrelin engages the ghrelin receptor or a ghrelin receptor complex. © 2017 The Authors.

We present a derma-respiratory syndrome in a patient occupationally exposed to trichloroethylene (TCE). At the beginning of its industrial use trichloroethylene was considered harmless. But, in time it showed a high noxious capacity. It produces an important and various pathology, which evolves as acute or chronic disease. The case we present shows that trichloroethylene can induce cutaneous pathology that excels contact dermatitis. It also proves that trichloroethylene can produce systemic effects (obstructive respiratory syndrome). The particularity of the case is based on the succession of the events, first the cutaneous and then the respiratory effects. A long period of time was necessary for the installation of the symptoms (for cutaneous and bronchial sensitization to take place). The case presented is the proof that trichloroethylene's great toxicity cannot be doubted and that the clinical forms due to sensitization to trichloroethylene can be dramatic.

Defective collagen biosynthesis in Marfan syndrome predisposes to dural defects such as dural ectasia, meningocele, and pseudomeningocele; thus, an increased index of suspicion for these conditions should be present in the clinical setting of Marfan syndrome. The authors describe a young woman with Marfan syndrome who was being treated with anticoagulants for a prosthetic heart valve and who presented with a spontaneous retroperitoneal hemorrhage requiring surgical evacuation. No CSF leak was encountered at surgery, but she developed progressively more severe positional headaches over the following year. She then experienced the sudden onset of acute urinary obstruction, at which time CT revealed a 17 × 15 × 13-cm presacral pseudomeningocele communicating with the thecal sac through a sacral bone defect. An anterior surgical approach was used for drainage of the pseudomeningocele as well as for primary closure of the dural defect with a bovine pericardial patch and autologous subcutaneous fat graft. After a short period of lumbar subarachnoid drainage of the CSF, the patient was able to resume normal activity without recurrent symptoms. To the authors' knowledge, such a pseudomeningocele in a patient with Marfan syndrome has been reported only twice, and this case features the largest pseudomeningocele to date. They also review the pertinent literature regarding presentation, diagnosis, and management of these lesions.

Chronic obstructive pulmonary disease and obstructive sleep apnea. Association, consequences and treatment.

Science.gov (United States)

Pronzato, C

2010-12-01

Obstructive sleep apnea syndrome (OSAS) and chronic obstructive pulmonary disease (COPD) are two diseases that often co-exist within an individual. This co-existence, known as overlap syndrome (OS), is the result of chance rather than a pathophysiological linkage and epidemiological studies indicate a prevalence of 1% in adult males. Patients vith OS have a more important sleep-related O2 desaturation than COPD patients with the same degree of bronchial obstruction and show an increased risk of developing hypercapnic respiratory failure and pulmonary hypertension when compared with patients affected by only one of he diseases. COPD and OSAS are independent risk factors for cardiovascular events and their co-existence in OS probably increases this risk. Evidence of systemic inflammation in COPD and sleep apnea and consequentely OS, is interesting because it may contribute to the pathogenesis of cardiovascular diseases. Treatment consists of continuous positive airway pressure (CPAP) or non-invasive positive pressure ventilation (NIPPV), with or without associated O2, for correction of the upper airway obstructive episodes and hypoxemia during sleep.

The aim of this study was to determine the metabolic biomarkers for abnormal Savda syndrome in patients with chronic obstructive pulmonary disease (COPD). Based on Traditional Uyghur Medicine (TUM) theory, a total of 103 patients with COPD were classified into abnormal Savda and non-abnormal Savda syndrome groups and 52 healthy volunteers acted as the control group. Blood samples from the three groups were analyzed using nuclear magnetic resonance (NMR) spectroscopy combined with orthogonal projection to latent structure-discriminant analysis. NMR tests showed that the regional distributions of the patients with COPD with abnormal Savda syndrome, those with non-abnormal Savda syndrome and the control group were completely separate (P>0.05). The patients with COPD with abnormal Savda syndrome exhibited relatively low levels of amino acids, glycoproteins and unsaturated lipids (PAbnormal Savda syndrome was one of the main types of syndrome among the patients with COPD; increased age, a longer duration of illness and a higher disease severity were characteristic of this type of syndrome. In addition, the present study provided biochemical evidence for the TUM theory-based classification of patients with COPD; these biomarkers can be used in the clinic for the diagnosis of COPD with abnormal Savda syndrome. The study also demonstrated that the plasma metabolic disorder in patients with COPD with abnormal Savda syndrome was more serious than that in the control and COPD with non-abnormal Savda syndrome groups. The plasma metabolic disorder was also associated with a low immune function of the body and endocrine and energy metabolism disorders.

2013-01-01

Full Text Available Obstructive sleep apnea (OSA may occur in association with obesity-hypoventilation (Pickwickian syndrome, a disorder of ventilatory control affecting individuals with morbid obesity. Through the pressor effects of chronic hypercapnia and hypoxemia, this syndrome may result in pulmonary hypertension, right heart failure, and massive peripheral edema. We present a case of severe scrotal edema in a 36-year-old male with OSA and obesity-hypoventilation syndrome. A tracheostomy was performed to relieve hypoxemia and led to dramatic improvement of scrotal edema. No scrotal surgery was necessary. Followup at two months showed complete resolution of scrotal edema, improvement in mental status, and normalization of arterial blood gas measurements. This case demonstrates that OSA and obesity-hypoventilation syndrome may present with massive scrotal edema. Furthermore, if OSA is recognized as the cause of right heart failure, and if the apnea is corrected, the resultant improvement in cardiac function may allow reversal of massive peripheral, including scrotal, edema.

Iikura, M

1995-06-01

The functional disorder of defecation after low anterior resection (LAR) was studied from the aspect of colonic motility in an experiment with dogs using a strain gage transducer, and the following results were obtained: 1) In early phase after LAR, the frequency of the colonic contractile waves increased at the proximal and distal sites of the anastomosis in both subgroups of dogs denervated and innervated of hypogastric and pelvic nerves. The increase was more remarkable at the distal site of the anastomosis. Also, the contractile waves were not propagated across the anastomosis. 2) After LAR, strong colonic contractions occurred during defecation only at the distal anastomosis. Various patterns of contraction time required for defecation were demonstrated as compared to a single pattern in control dogs. 3) The frequency of the occurrence of colonic contractile waves and the propagation of the contraction tended to be normalized with time after LAR both in denervated and innervated groups, though the recovery was faster in the latter subgroup. 4) The frequency of defecation increased after LAR both in denervated and innervated groups compared to be in the control dogs, though more remarkable in the denervated groups. Although tended to be gradually normalized with time after LAR, the colectomized dogs required a long time for normalization of the frequency of defecation. These results suggested the significant effect of reduction in reservoir space and disturbed continuity of intramural plexus caused by colectomy. Less severity, however, of functional disorder of defecation and earlier recovery from colonic motility disorder in the subgroup of the dogs innervated of autonomic nerves indicated usefulness of retaining autonomic nerves in colectomy.

To analyze the correlation between risk factors and ischemic cerebral stroke of wind-phlegm collateral obstruction syndrome and qi deficiency blood stasis syndrome. Totally 900 patients of the two syndrome types were recruited. Risk factors correlated to ischemic cerebral stroke such as gender, age, time of onset, site of infarction, tongue proper, tongue fur, pulse picture, hypertension, diabetes, past stroke history, hyperlipidemia, hematocrit, smoking, drinking, genetic factor, blood type, complications were analyzed using Chi-square test and non-conditional Logistic regression analysis. Statistical significance existed between the two syndrome types in age (X2 = 8.2392, P = 0.0413), hyperlipidemia (X2 = 4.8386, P = 0.0278), tongue proper (X2 = 7.9470, P = 0.0048), and tongue fur (X2 = 4.3298, P = 0.0375). Statistical significance existed between the two syndrome types in hyperlipidemia, tongue proper, and tongue fur, and their OR value was 0.699 (P = 0.0282), 0.332 (P =0.0071), and 0.667 (P = 0.0382) respectively. The OR value of the past stroke history was 3.226 (P = 0.0314), that of complications 0.203 (P = 0.0705), and that of anterior circulation infarction 0.214 (P = 0.0098). Among different ages groups, the constituent ratio of qi deficiency blood stasis syndrome was obviously higher than that of wind-phlegm collateral obstruction syndrome. Besides, patients of qi deficiency blood stasis syndrome were liable to suffer from hyperlipidemia, anterior circulation infarction, and complications. The age, blood lipid levels, site of infarction, complications are closely correlated with Chinese syndrome types of ischemic cerebral stroke, which can provide objective indices for typing ischemic cerebral stroke.

Children with Down syndrome (DS) have a high prevalence of sleep problems, including behavioural sleep disturbances and obstructive sleep apnea. Sleep problems are associated with a wide range of adverse health effects. Since children with DS are already known to have many comorbidities, they are particularly susceptible for the negative impact of sleep problems. Aim of this study is (1) to evaluate the prevalence of sleep problems in children with DS, (2) compare the prevalence of sleep problems in children with DS with a community sample of typical developing school-aged children, and (3) to correlate the existence of sleep problems in children with DS and OSA. Children enrolled at the multidisciplinary Down team of the University Hospital Antwerp and seen at the ENT department were eligible for this study. The prevalence of sleep problems was evaluated by the use of the Child Sleep Habits Questionnaire (CSHQ) and a full overnight polysomnography was performed to screen for obstructive sleep apnea. Parents of fifty-four children with DS, aged 7.5 years (5.4-11.6), completed the CSHQ and an overall prevalence of sleep problems was found in 74.1%. In 57.1% of the children OSA was diagnosed with a median obstructive apnea-hypopnea index (oAHI) 7.25/h (5.7-9.8). Overall sleep problems were not age-or gender related, however boys suffer more from daytime sleepiness. Symptoms of sleep disordered breathing correlate with parasomnias, a longer sleep duration and more daytime sleepiness. No correlation was found between sleep problems and underlying OSA. Children with Down syndrome have a significantly higher prevalence of sleep problems, compared to normal developing healthy school-aged children. We didn't find any correlation between the parental report of sleep problems and underlying OSA, or OSA severity. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Full Text Available   Introduction: Sulfur mustard (SM, a toxic alkylating gas, can cause serious long-term pulmonary complications such as chronic obstructive pulmonary disease (COPD. Metabolic syndrome (MetS is one of the important comorbidities of COPD. This study was designed to evaluate the frequency of metabolic syndrome in Iranian chemical warfare patients (CWPs with COPD. Materials and Methods: Thirty CWPs with a mean age of 46.93± 6.8 were enrolled in this study. The following parameters were studied in: complete pulmonary function tests, health-related quality of life, serum triglycerides (TG, high density lipoprotein (HDL and fasting blood sugar (FBS levels. Additionally, 32 COPD patients and 56 healthy persons were considered as control groups who were matched to CWPs. Results: We found a statistically significant difference in the frequency of MetS between the COPD patients and the healthy control group (p=0.04. Additionally, we observed a statistically significant difference in the mean HDL levels among these groups (p=

Chronic obstructive pulmonary disease and obstructive sleep apnea: overlaps in pathophysiology, systemic inflammation, and cardiovascular disease.

2012-02-01

Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea syndrome represent two of the most prevalent chronic respiratory disorders in clinical practice, and cardiovascular diseases represent a major comorbidity in each disorder. The two disorders coexist (overlap syndrome) in approximately 1% of adults but asymptomatic lower airway obstruction together with sleep-disordered breathing is more prevalent. Although obstructive sleep apnea syndrome has similar prevalence in COPD as the general population, and vice versa, factors such as body mass index and smoking influence relationships. Nocturnal oxygen desaturation develops in COPD, independent of apnea\\/hypopnea, and is more severe in the overlap syndrome, thus predisposing to pulmonary hypertension. Furthermore, upper airway flow limitation contributes to nocturnal desaturation in COPD without apnea\\/hypopnea. Evidence of systemic inflammation in COPD and sleep apnea, involving C-reactive protein and IL-6, in addition to nuclear factor-kappaB-dependent pathways involving tumor necrosis factor-alpha and IL-8, provides insight into potential basic interactions between both disorders. Furthermore, oxidative stress develops in each disorder, in addition to activation and\\/or dysfunction of circulating leukocytes. These findings are clinically relevant because systemic inflammation may contribute to the pathogenesis of cardiovascular diseases and the cell\\/molecular pathways involved are similar to those identified in COPD and sleep apnea. However, the pathophysiological and clinical significance of systemic inflammation in COPD and sleep apnea is not proven, and thus, studies of patients with the overlap syndrome should provide insight into the mechanisms of systemic inflammation in COPD and sleep apnea, in addition to potential relationships with cardiovascular disease.

Poor sanitation remains a major public health concern linked to several important health outcomes; emerging evidence indicates a link to childhood stunting. In India over half of the population defecates in the open; the prevalence of stunting remains very high. Recently published data on levels of stunting in 112 districts of India provide an opportunity to explore the relationship between levels of open defecation and stunting within this population. We conducted an ecological regression analysis to assess the association between the prevalence of open defecation and stunting after adjustment for potential confounding factors. Data from the 2011 HUNGaMA survey was used for the outcome of interest, stunting; data from the 2011 Indian Census for the same districts was used for the exposure of interest, open defecation. After adjustment for various potential confounding factors--including socio-economic status, maternal education and calorie availability--a 10 percent increase in open defecation was associated with a 0.7 percentage point increase in both stunting and severe stunting. Differences in open defecation can statistically account for 35 to 55 percent of the average difference in stunting between districts identified as low-performing and high-performing in the HUNGaMA data. In addition, using a Monte Carlo simulation, we explored the effect on statistical power of the common practice of dichotomizing continuous height data into binary stunting indicators. Our simulation showed that dichotomization of height sacrifices statistical power, suggesting that our estimate of the association between open defecation and stunting may be a lower bound. Whilst our analysis is ecological and therefore vulnerable to residual confounding, these findings use the most recently collected large-scale data from India to add to a growing body of suggestive evidence for an effect of poor sanitation on human growth. New intervention studies, currently underway, may shed more

Objective: To evaluate the application value of MRI fast SPGR single slice scan in patients with obstructive sleep apnea-hypopnea syndrome when comparing the images between fast SPGR single slice scan and continuous dynamic scan. Methods: Eighteen patients with obstructive sleep apnea-hypopnea syndrome were examined by fast SPGR single slice scan and continuous dynamic scan in turn. Fast SPGR single slice scans were conducted when the phases of apnea, inspiration and expiration appeared on the respiratory wave of the subjects. Fast SPGR continuous dynamic scans were conducted when the patients were awake and apneic. The scan planes were median sagittal plane and axial planes (the slice of middle part of palate, the slice of inferior part of palate, the slice of middle part of lingual root and the slice of 0.5 cm beneath the free margin of epiglottis). The obstructed sites and the cross-sectional areas of upper airway were compared between the two scan methods. Results: Seven cases showed complete obstruction at the narrowest sites of upper airway when apnea appeared; eleven cases showed marked decrease in cross-sectional areas at the narrowest sites compared with the areas when the patients were awake; two cases manifested multiple narrowness. The obstructed sites showed by the two scan methods were same. The difference of the cross-sectional areas of upper airway between the two scan methods was insignificant (P > 0.05). Conclusion: Fast SPGR single slice scan can accurately reflect the obstructed sites of upper airway when the breath breaks off and is the complementary method of continuous dynamic scan. Sometimes, single slice scan can replace continuous dynamic scan.

Full Text Available Obstructive sleep apnoea is a condition which affects an estimated 50% of children with Down syndrome, particularly in their early years. It can cause serious sequelae in affected children but may not be recognised by parents or health professionals. Routine screening has been recommended in some countries but is not standard practice. There are no validated questionnaire based tools available to screen this population of children for this particular sleep-related disorder. Using existing validated sleep questionnaire items, we have developed a questionnaire to screen children with Down syndrome up to 6 years of age for obstructive sleep apnoea, which corresponds with the recommendations made in UK national guidelines. This paper describes these first steps in demonstrating content validity for a new questionnaire which will be subject to further in-depth psychometric analysis. Relevance, clarity and age-appropriateness was rated for 33 items using a content review questionnaire by a group of 18 health professionals with expertise in respiratory paediatrics, neurodevelopmental paediatrics and sleep physiology. The content validity index was calculated for individual items and contributed to decisions about item inclusion. Scale level content validity index for the modified questionnaire of 14 items was at an accepted level of 0.78. Two parents of children with Down syndrome took part in cognitive interviews after completing the modified questionnaire. We describe the development of this 14 item questionnaire to screen for OSA in children with DS from infancy to 6 years.

Congenital high airway obstruction syndrome (CHAOS) is a rare disorder defined as any fetal abnormality that obstructs the larynx or trachea. Prompt airway intervention at delivery after accurate prenatal diagnosis may allow survival of this otherwise fatal condition. To identify prenatal MRI findings in CHAOS, to compare these findings with those of fetal US, to determine if imaging alters diagnosis and management decisions, and to correlate prenatal with postnatal imaging findings. Records and MRI scans of ten fetuses with CHAOS were reviewed, and the findings correlated with outside and same-day fetal US and postnatal imaging findings. Fetal lung volumes were measured on MRI scans. Large lung volumes were found in 90% of the fetuses. Increased lung signal intensity, inverted diaphragm, and a dilated, fluid-filled lower airway were identified in all. The obstruction level was identified in 90%. MRI changed screening US diagnosis in 70%, but was concordant with the tertiary care US imaging in 90%. Seven fetuses were terminated or died in utero, and three fetuses survived after ex utero intrapartum tracheostomy placement. Autopsy or bronchoscopy performed in 60% confirmed CHAOS. Postnatal chest radiographs and CT showed hyperinflation, while US and fluoroscopy showed diminished diaphragmatic motion. MRI demonstrates large lung volumes, increased lung signal intensity, inverted diaphragm, and dilated fluid-filled lower airway, and usually identifies the obstruction level. The degree of correlation between MRI and tertiary prenatal US is high, but CHAOS is frequently misdiagnosed on screening US. Correct diagnosis may enable planned airway management. Voluminous lungs and diaphragmatic abnormalities persist on postnatal imaging. (orig.)

Simón, Miguel A; Bueno, Ana M

The aim of this study was to evaluate the efficacy of biofeedback therapy in the treatment of dyssynergic defecation in chronically constipated community-dwelling elderly women. After an initial assessment phase carried out during 1 month, 20 chronically constipated women with dyssynergic defecation were randomly assigned to either electromyographic biofeedback (EMG-BF) group (n=10) or control group (n=10). Outcome measures used to evaluate the efficacy of treatment were weekly stool frequency, sensation of incomplete evacuation, difficulty evacuation level, mean EMG-activity (μV) of the external anal sphincter during straining to defecate and Anismus index. The results obtained in this randomized controlled trial showed significant differences between the groups in all the dependent variables after 1 month of treatment. Moreover, there was no difference between the groups neither in age nor in the duration of chronic constipation symptoms. At the follow-up, 3 months later, clinical gains were maintained. This study demonstrates that the EMG-BF is an effective behavioral therapy for the treatment of dyssynergic defecation in community-dwelling elderly women.

To establish the diagnostic test accuracy of evacuation proctography, magnetic resonance imaging (MRI), transperineal ultrasonography, and endovaginal ultrasonography for detecting posterior pelvic floor disorders (rectocele, enterocele, intussusception, and anismus) in women with obstructed defecation syndrome and secondarily to identify the most patient-friendly imaging technique. In this prospective cohort study, 131 women with symptoms of obstructed defecation syndrome underwent evacuation proctogram, MRI, and transperineal and endovaginal ultrasonography. Images were analyzed by two blinded observers. In the absence of a reference standard, latent class analysis was used to assess diagnostic test accuracy of multiple tests with area under the curve (AUC) as the primary outcome measure. Secondary outcome measures were interobserver agreement calculated as Cohen's κ and patient acceptability using a visual analog scale. No significant differences in diagnostic accuracy were found among the imaging techniques for all the target conditions. Estimates of diagnostic test accuracy were highest for rectocele using MRI (AUC 0.79) or transperineal ultrasonography (AUC 0.85), for enterocele using transperineal (AUC 0.73) or endovaginal ultrasonography (AUC 0.87), for intussusception using evacuation proctography (AUC 0.76) or endovaginal ultrasonography (AUC 0.77), and for anismus using endovaginal (AUC 0.95) or transperineal ultrasonography (AUC 0.78). Interobserver agreement for the diagnosis of rectocele (κ 0.53-0.72), enterocele (κ 0.54-0.94) and anismus (κ 0.43-0.81) was moderate to excellent, but poor to fair for intussusception (κ -0.03 to 0.37) with all techniques. Patient acceptability was better for transperineal and endovaginal ultrasonography as compared with MRI and evacuation proctography (P<.001). Evacuation proctography, MRI, and transperineal and endovaginal ultrasonography were shown to have similar diagnostic test accuracy. Evacuation proctography

Obstructive sleep apnea syndrome and cognitive impairment: effects of CPAP

Directory of Open Access Journals (Sweden)

Alessandra Giordano

2011-10-01

Full Text Available Obstructive Sleep Apnea Syndrome (OSAS is a sleep disorder characterised by repetitive episodes of upper airway obstruction (apnea or reduced airflow (hypopnoea despite persistent respiratory effort. Apnea is defined as the cessation of breathing for at least 10 seconds during sleep, while hypopnoea is defined as at least 30% reduction in airflow for 10 seconds associated with oxygen desaturation and sleep fragmentation. The presence in the general population is about 4%. The principal symptoms are: excessive daytime sleepiness (EDS, snoring, dry throat, morning headache, night sweats, gastro-esophageal reflux, and increased blood pressure.Long term complications can be: increased cardio-cerebrovascular risk and cognitive impairment such as deficiency in attention, vigilance, visual abilities, thought, speech, perception and short term memory.Continuous Positive Airway Pressure (CPAP is currently the best non-invasive therapy for OSAS.CPAP guarantees the opening of upper airways using pulmonary reflexive mechanisms increasing lung volume during exhalation and resistance reduction, decreasing electromyografical muscular activity around airways.The causes of cognitive impairments and their possible reversibility after CPAP treatment have been analysed in numerous studies. The findings, albeit controversial, show that memory, attention and executive functions are the most compromised cognitive functions.The necessity of increasing the patient compliance with ventilotherapy is evident, in order to prevent cognitive deterioration and, when possible, rehabilitate the compromised functions, a difficult task for executive functions.

We determined the distribution of the Arg16Gly and Gln27Glu polymorphisms of the beta-2 adrenergic receptor gene (ADRB2) in patients with obstructive sleep apnea syndrome as well as a control group in Northeastern Turkey. A total of 52 patients diagnosed with obstructive sleep apnea in a sleep laboratory and 78 control subjects were examined. Peripheral blood samples were taken from patients diagnosed with obstructive sleep apnea by polysomnography. DNA was extracted from blood samples and amplified using polymerase chain reaction. Amplification products were digested with restriction enzymes to investigate gene polymorphisms. Restriction products were extracted from agarose gel electrophoresis and polymorphisms were analyzed using gel images. The Arg16Gly polymorphism was observed in 18 of 52 patients and in 23 of 78 controls. The Gln27Glu polymorphism was observed in 21 of 52 patients and in 28 of 78 controls. In conclusion, there was no correlation among polymorphic frequencies between patient and control groups. Based on the results, these polymorphisms do not contribute to the clinical diagnosis of this syndrome. However, the distribution of Arg16Gly vs Gln27Glu polymorphisms may contribute to obesity in patients with a body mass index greater than 30 (P sleep apnea disease are changed.

The purpose of this study was to apply dynamic MRI for the positional diagnosis of airway obstruction during snoring and sleep apnea and to compare the apnea hypopnea index (AHI) and the square measure of the pharynx obtained before and after laser-assisted uvula-palate-pharyngoplasty (LAUP). From December 1997 to October 1998, dynamic MRI and overnight monitoring were performed at the hospital of Tokyo Medical University on 42 patients who complained of snoring and symptoms related to sleep apnea syndrome (SAS). Of the 42 patients, four exhibited collapse at the position of the soft palate (soft palate type) as diagnosed by dynamic MRI, and four exhibited collapse at the position of the soft palate as well as the tongue (complex type). LAUP was performed on these eight patients with obstructive SAS (OSAS). After LAUP, the AHI of these eight patients with OSAS decreased significantly (p<0.05). The square measure of the pharynx of these eight patients was increased (p<0.01). The AHI of all four patients with soft-palate obstruction decreased, and the square measure of the pharynx of three of these four patients increased. The AHI of three of four patients with the complex type decreased, while the square measure of the pharynx of two of these four patients increased. (author)

We wanted to evaluate whether both the colonic transit time (CTT) and defecography are necessary for diagnosing constipated patients, and we also wanted to assess the defecographic findings of patients with outlet obstruction on CTT. Over the recent 3 years, 26 patients (21 women and 5 men, mean age: 59 years) underwent both CTT and defecography because of their chronic constipations or defecation difficulty. The mean interval between the 2 studies was 48 days. Colonoscopy, barium enema and manometry were performed in 22, 8 and all the patients, respectively. On CTT, 13 patients (50.0%) were normal and 13 patients (50.0%) were abnormal; the abnormal results were composed of outlet obstruction (n = 8, 30.8%), outlet obstruction and colon inertia (n = 2, 7.7%), colon inertia (n = 2, 7.7%), and outlet obstruction and hindgut dysfunction (n = 1, 3.8%). On defecography, 6 patients (23.1%) were normal and 20 patients (76.9%) were abnormal; the results were composed of rectocele (n = 8, 30.7%), rectocele and perineal descent syndrome (PDS; n = 4, 15.4%), PDS and rectal intussusception (n = 3, 11.5%), spastic pelvic floor syndrome (SPFS; n = 3, 11.5%), rectocele and SPFS (n = 1, 3.8%), and rectal intussusception (n = 1, 3.8%). Of the 11 patients with outlet obstruction on CTT, rectocele (n = 4, 36.4%), SPFS (n = 1, 9.1%), rectocele and PDS (n = 1, 9.1%), and PDS and rectal intussusception (n = 1, 9.1%) were demonstrated on defecography, except for the 4 normal cases. Both CTT and defecography were necessary for diagnosing the patients with chronic constipation in compensation, and 63.6% of the patients with pelvic outlet obstruction showed an abnormal pelvic defecation function

Over the recent 3 years, 26 patients (21 women and 5 men, mean age: 59 years) underwent both CTT and defecography because of their chronic constipations or defecation difficulty. The mean interval between the 2 studies was 48 days. Colonoscopy, barium enema and manometry were performed in 22, 8 and all the patients, respectively. On CTT, 13 patients (50.0%) were normal and 13 patients (50.0%) were abnormal; the abnormal results were composed of outlet obstruction (n = 8, 30.8%), outlet obstruction and colon inertia (n = 2, 7.7%), colon inertia (n = 2, 7.7%), and outlet obstruction and hindgut dysfunction (n = 1, 3.8%). On defecography, 6 patients (23.1%) were normal and 20 patients (76.9%) were abnormal; the results were composed of rectocele (n = 8, 30.7%), rectocele and perineal descent syndrome (PDS; n = 4, 15.4%), PDS and rectal intussusception (n = 3, 11.5%), spastic pelvic floor syndrome (SPFS; n = 3, 11.5%), rectocele and SPFS (n = 1, 3.8%), and rectal intussusception (n = 1, 3.8%). Of the 11 patients with outlet obstruction on CTT, rectocele (n = 4, 36.4%), SPFS (n = 1, 9.1%), rectocele and PDS (n = 1, 9.1%), and PDS and rectal intussusception (n = 1, 9.1%) were demonstrated on defecography, except for the 4 normal cases. Both CTT and defecography were necessary for diagnosing the patients with chronic constipation in compensation, and 63.6% of the patients with pelvic outlet obstruction showed an abnormal pelvic defecation function.

Objective: To evaluate the clinical value of percutaneous transluminal angioplasty with stenting (PTAS) for the treatment of superior vana cava obstructive syndrome (SVCOS). Methods: 15 cases of SVCOS including 10 cases of lung cancer with mediastinal lymphatic metastasis, 3 cases as malignant lymphoma and 2 cases of esophageal cancer with mediastinal lymphadenopathy, were undergone right subclavian vein or elbow vein catheterization for pressure measurement and DSA imaging of SVC with displaying the obstructive characteristics. A self-expanding stent was then implanted through right femoral vein catheterization. Results: 15 cases were all successfully under-taken angioplasty and stenting, except 1 case with a long stricture over 10 cm requiring 2 stents. After successful stent placement, DSA revealed smooth flow of contrast with almost normal diameter of SVC lumen, together with disappearance or relief of SVCOS. The SVC pressure decreased from 30.5±2.3 cmH 2 O down to 8.8 ± 1.5 cmH 2 O after recanalization, with a significant difference in statistics (P<0.01). All the patients were followed up for 6 months and obstructive symptom did not reappear except one case complicated with thrombosis which was treated by regional thrombolysis and balloon dilation leading to obviously improved symptom. Conclusion: PTAS for the treatment of SVCOS is effective, safe, simple and of less complications. (authors)

Full Text Available Gastric outlet obstruction caused by a large gallstone in the duodenum or pylorus (Bouveret's syndrome is a rare complication of gallstone disease. The presenting symptoms are often nonspecific and include nausea, vomiting, epigastric pain and a history of gallbladder disease. Although the diagnosis is established only at surgery in many cases, preoperative recognition by imaging techniques and endoscopy is desirable. Surgical treatment aims at removal of the ectopic gallstone, closure of the fistula and cholecystectomy. A case of Bouveret's syndrome is presented where endoscopic extraction of the duodenal gallstone was accomplished providing definitive treatment for this patient.

Full Text Available Introduction: Patients with obstructive sleep apnea syndrome usually present with changes in upper airway morphology and/or body fat distribution, which may occur throughout life and increase the severity of obstructive sleep apnea syndrome with age. Objective: To correlate cephalometric and anthropometric measures with obstructive sleep apnea syndrome severity in different age groups. Methods: A retrospective study of cephalometric and anthropometric measures of 102 patients with obstructive sleep apnea syndrome was analyzed. Patients were divided into three age groups (≥20 and <40 years, ≥40 and <60 years, and ≥60 years. Pearson's correlation was performed for these measures with the apnea-hypopnea index in the full sample, and subsequently by age group. Results: The cephalometric measures MP-H (distance between the mandibular plane and the hyoid bone and PNS-P (distance between the posterior nasal spine and the tip of the soft palate and the neck and waist circumferences showed a statistically significant correlation with apnea-hypopnea index in both the full sample and in the ≥40 and <60 years age group. These variables did not show any significant correlation with the other two age groups (<40 and ≥60 years. Conclusion: Cephalometric measurements MP-H and PNS-P and cervical and waist circumfer- ences correlated with obstructive sleep apnea syndrome severity in patients in the ≥40 and <60 age group.

Obstructive lung diseases represent a major health problem worldwide due to their high prevalence associated with elevated socioeconomic costs. Bronchial asthma and chronic obstructive pulmonary disease are chronic obstructive ventilatory disorders with airway inflammation, however they are separate nosological entities based on thedifferent development, diagnostic and therapeutic approaches, and prognostic features. However, these diseases may coexist and can be defined as the coexistence of increased variability of airflow in a patient with incompletely reversible airway obstruction. This phenotype is called asthma - chronic obstructive pulmonary disease overlap syndrome. The syndrome is a clinical and scientific challenge as the majority of these patients have been excluded from the clinical and pharmacological trials, thus well-defined clinical characteristics and therapeutic approaches are lacking. The aim of this review is to summarize the currently available literature focusing on pathophysiological and clinical features, and discuss possible therapeutic approaches of patients with asthma - chronic obstructive pulmonary disease overlap syndrome.

Full Text Available Aim. To assess the impact of metabolic abnormalities in combination with obstructive sleep apnea on endothelial function and vascular stiffness parameters in patients with arterial hypertension 1-2 degrees. Material and methods. Patients (n=74 with metabolic syndrome and obstructive sleep apnea were included into the study. All patients underwent cardiorespiratory monitoring of sleep using SomnoCheck2 device (Wiennmann, Germany and were divided into two groups based on its results. Patients with apnea-hypopnea index (AHI <30 episodes per hour were included into group 1 and patients with AHI >30 episodes per hour – into group 2. Monitoring of ambulatory blood pressure (BP and arterial stiffness was performed by the device BPLab ("Peter Telegin", Russia. Endothelial function was assessed in a probe of flow-mediated dilation by the ultrasound device MyLab 90 (Esaote, Italy. Diameter of the common carotid artery (DCCA and the intima-media thickness (IMT were determined. Results. Patients with AHI >30 episodes per hour had higher mean daily and night systolic BP and pulse BP in aorta and brachial artery. Pulse wave velocity in aorta in per day averaged was also higher in these patients (8.2±0.8 vs 9.1±1.1 m/sec; p<0.05. Mean level of flow-mediated dilation was significantly lower in patients with severe sleep apnea> (8.8% (5.6; 13.1 vs 4.5% (2.2; 8.0; p<0.05. Prevalence of negative index of reactivity in group 2 was 2 times higher than this in group 1. An increase in IMT and DCCA in patients with severe obstructive sleep apnea was also revealed. Conclusion. Severe sleep apnea in patients with metabolic syndrome in combination with hypertension aggravates structural changes and endothelial dysfunction of the main arteries, as well as contributes to the progression of atherosclerosis.

A 47-year-old female patient had a subclinical superior vena caval syndrome which developed into the \\'full blown\\' acute condition when she was placed into the left lateral position after mediastinoscopy. She developed airway obstruction requiring urgent re-intubation and subsequent admission to the intensive care unit. This subclinical condition might have been suspected pre-operatively if closer attention had been paid to the history, physical examination and review of the computerised axial tomography scan: she had a history of intermittent dysponea, wheeze and cough which was worse on waking and improved as the day progressed, she had a positive Pemberton\\'s sign and the computerised axial tomography scan showed that the lesion was encroaching on the superior vena cava.

Studies suggest an independent association between Obstructive Sleep Apnoea Syndrome (OSAS) and cardiovascular death. The purpose of our study is to examine doctors\\' awareness of this association and to determine whether this correlates with recording of OSAS on death certificates. We contacted the Central Statistics Office (CSO) and obtained relevant mention of OSAS on death certificates. We surveyed doctors on their view of OSAS-related deaths, CSO data from 2008-2011 reveal two deaths with OSAS documented as a direct cause and 52 deaths with OSAS as a contributory cause. Seventy-five doctors\\' surveyed (41%) believe OSAS can be a direct cause of death and 177 (96%) believe OSAS can be an indirect cause of death. Only 22 (12%) had putdown OSAS as a cause of death. OSAS is seldom recorded on death certificates. This is at odds with epidemiological forecasts and contrary to an opinion poll from a selection of doctors.

The syndrome of intestinal pseudo-obstruction is a complex of signs and symptoms of intestinal obstruction without evidence of mechanical obstruction of the intestinal lumen. A patient with radiation-induced intestinal pseudoobstruction is described. The patient is a 74-year old woman with a history of chronic diarrhea, recurrent episodes of crampy abdominal pain, nausea and vomiting since receiving a 13,000 rad radiation dose to the pelvis in 1954. She has been hospitalized on many occasions for symptoms and signs of bowel obstruction. Upper gastrointestinal contrast roentgenograms with small bowel follow-through done during these episodes revealed multiple dilated loops of small bowel with no obstructing lesion. Barium enemas revealed no obstructing lesion. Each episode resolved with conservative therapy. Other secondary causes for intestinal pseudo-obstruction were ruled out in our patient. She gave no history of familial gastrointestinal disorders. Although postirradiation motility abnormalities have been demonstrated experimentally this is the first report of radiation induced intestinal pseudo-obstruction

Full Text Available Chronic and repetitive intermittent hypoxia and dysfunction of sleep architecture mainly contribute to obstructive sleep apnea syndrome (OSAS. More and more evidences demonstrate it is a systemic disease, which is common encountered in clinic and strongly related to the systemic lesion of central nervous system. The central nervous system complications comprise cognitive impairment, brain atrophy and the growing risk of stroke and so on. Early treatment for OSAS has a positive significance on complications of central nervous system, and even the damage can be completely reversed.

Constipation is a common feature of Prader-Willi syndrome. Research exploring the prevalence, cause and treatment options for constipation is limited and lacks objective measurements such as anorectal manometry. We report a case of a 16-year-old lady with Prader-Willi syndrome presenting with rectal pain and constipation for 2 years despite multiple medications and weekly enemas. She also noted passive fecal incontinence that required frequent manual disimpactions. Anorectal manometry revealed an abnormal relaxation of the puborectalis and external sphincter muscles on push maneuvers suggesting dyssynergic defecation and rectal hypersensitivity. Contraction and relaxation of her pelvic muscles were recorded with electromyography. Relaxation of the puborectalis muscle improved significantly after three biofeedback sessions. Patient was successfully tapered off laxatives and has been maintained on linaclotide only. Dyssynergic defecation may be a common finding in Prader-Willi syndrome. In selected cases we recommend anorectal manometry to identify neuromuscular dysfunction and subsequent biofeedback therapy depending on the degree of mental retardation to minimize overuse of laxatives.

Congenital high airway obstruction syndrome (CHAOS) is a rare life-threatening syndrome. Most cases are diagnosed prenatally by US. We report a fetus with this syndrome that showed a unique course revealed on MRI. Ultrasonography at 22 weeks demonstrated that the fetus had ascites and bilaterally enlarged hyperechoic lungs. Congenital infection, congenital cystic adenomatoid malformation or CHAOS was suspected. Subsequent MRI performed at 24 weeks demonstrated bilaterally enlarged high-signal lungs, dilated bronchi, massive ascites, subcutaneous oedema and polyhydramnios. MRI confirmed the diagnosis of CHAOS. A second MRI at 35 weeks showed that the bilateral lung enlargement, ascites, oedema and polyhydramnios had resolved, but that the appearance of the airway was unchanged. The infant was delivered by caesarean section at 38 weeks of gestation and immediate tracheostomy was performed. This spontaneous regression was explained by a tracheo-oesophageal fistula that may have decreased the intrathoracic pressure. (orig.)

2003-04-01

Full Text Available Data from the Chagas Disease Control Program indicate a growing domiciliary and peridomiciliary invasion of Triatoma rubrovaria in the State of Rio Grande do Sul, where it has become the most frequent triatomine species captured there since the control of T. infestans. Bionomic characteristics that could influence the vectorial capacity of T. rubrovaria as vector of Trypanosoma cruzi were evaluated: patterns of (i feeding, (ii defecation, and (iii resistance to starvation, using insects fed on mice. Fifty three percent of the females showed a defecation pattern conducive to chagasic transmission, defecating either on or near the bite site. The averages of the resistance to starvation varied from 48.1 to 179 days, for the first and fifth nymphal stages, respectively. Our study shows that with respect to the patterns of feeding, defecation and resistance to fasting, T. rubrovaria presented similar rates to the ones observed for other effective vector species, such as T. infestans. Thus, based on our studies we conclude that T. rubrovaria has biological characteristics that can positively influence its capacity to become infected and transmit T. cruzi, and also to keep residual populations after chemical control interventions.

Bowel habits vary depending on food consumption and genetic factors. The knowledge regarding this physiological phenomenon is limited. Thorough understanding of normal bowel habits is essential for correct diagnosis of defecation disorders. This study evaluated the normal bowel habits of Sri Lankan children. Children ages 10 to 16 years were randomly selected from 5 schools in 4 districts. Those without defecation disorders were recruited. Details regarding their bowel habits during previous 2 months were collected using a validated, self-administered questionnaire. A total of 2273 children were enrolled (mean age 13.2 years, SD 1.7 years, boys 49.7%). Of them, 1748 (76.9%) opened bowels once daily, whereas 149 (6.6%) and 11 (0.5%) had 3/day defecations, respectively. Stool consistency was normal in 1997 (87.9%), hard in 86 (3.8%), and changing consistency in 163 (7.1%). Straining was present in 639 (28.1%), painful defecation in 241 (10.6%), and bleeding in 49 (2.2%). One hundred six (4.7%) children reported stool withholding. Bulky stool was present in 158 (7.0%). Straining, bulky stools, and withholding posture were more common in boys, whereas painful defecation and bleeding were reported more often in girls (Pwar-affected areas (P < 0.05). Bowel frequency < 3/week, bulky stools, painful defecation, straining, and withholding posture were more common in those exposed to stressful life events (P < 0.05). The present study provides data on normal bowel habits of Sri Lankan schoolchildren and provides a firm platform to evaluate defecation disorders in them.

We aimed to study survival and causes of death in patients with ST-elevation acute coronary syndrome (STE-ACS) with and without obstructive coronary artery disease (CAD). We included 4793 consecutive patients with STE-ACS triaged for acute coronary angiography at a large cardiac invasive centre (2009-2014). Of these, 88% had obstructive CAD (stenosis ≥50%), 6% had non-obstructive CAD (stenosis 1-49%), and 5% had normal coronary arteries. Patients without obstructive CAD were younger and more often female with fewer cardiovascular risk factors. Median follow-up time was 2.6 years. Compared with patients with obstructive CAD, the short-term hazard of death (≤30 days) was lower in both patients with non-obstructive CAD [hazard ratio (HR) 0.49, 95% confidence interval (CI) 0.27-0.89, P = 0.018] and normal coronary arteries (HR 0.31, 95% CI 0.11-0.83, P = 0.021). In contrast, the long-term hazard of death (>30 days) was similar in patients with non-obstructive CAD (HR 1.15, 95% CI 0.77-1.72, P = 0.487) and higher in patients with normal coronary arteries (HR 2.44, 95% CI 1.58-3.76, P Causes of death were cardiovascular in 70% of patients with obstructive CAD, 38% with non-obstructive CAD, and 32% with normal coronary arteries. Finally, patients without obstructive CAD had lower survival compared with an age and sex matched general population. STE-ACS patients without obstructive CAD had a long-term risk of death similar to or higher than patients with obstructive CAD. Causes of death were less often cardiovascular. This suggests that STE-ACS patients without obstructive CAD warrant medical attention and close follow-up. Published on behalf of the European Society of Cardiology.

The afferent loop syndrome corresponds to an acute or chronic obstruction of the afferent loop following a partial gastrectomy with Billroth II gastro-jejunal anastomosis. We describe the case of a 77-year-old man with history of partial gastrectomy for peptic ulcer disease performed 31 years ago and currently admitted for jaundice and poor general status. MR imaging showed dilatation of biliary and pancreatic ducts and showed a soft tissue mass between the afferent loop and the residual stomach. Endoscopy showed complete obstruction of the afferent loop by a biopsy-proven adenocarcinoma. The patient died of sepsis shortly after endoscopy of septicemia. (authors)

Obstructive Sleep Apnoea Syndrome and Weight Loss: Review

Directory of Open Access Journals (Sweden)

Douglas C. Cowan

2012-01-01

Full Text Available Obstructive sleep apnoea (OSA syndrome is common, and obesity is a major risk factor. Increased peripharyngeal and central adiposity result in increased pharyngeal collapsibility, through increased mechanical loading around the upper airway, reduced tracheal traction on the pharynx, and reduced neuromuscular activity, particularly during sleep. Significant and sustained weight loss, if achieved, is likely to be a useful therapeutic option in the management of OSA and may be attempted by behavioural, pharmacological, and surgical approaches. Behavioural therapy programs that focus on aspects such as dietary intervention, exercise prescription patients and general lifestyle counselling have been tested. Bariatric surgery is an option in the severely obese when nonsurgical measures have failed, and laparoscopic adjustable gastric banding and Roux-en-Y gastric bypass are the most commonly employed techniques in the United Kingdom. Most evidence for efficacy of surgery comes from cohort studies. The role of sibutramine in OSA in the obese patients has been investigated, however, there are concerns regarding associated cardiovascular risk. In this paper the links between obesity and OSA are discussed, and the recent studies evaluating the behavioural, pharmacological and surgical approaches to weight loss in OSA are reviewed.

TrpA1 Regulates Defecation of Food-Borne Pathogens under the Control of the Duox Pathway.

Directory of Open Access Journals (Sweden)

Full Text Available Pathogen expulsion from the gut is an important defense strategy against infection, but little is known about how interaction between the intestinal microbiome and host immunity modulates defecation. In Drosophila melanogaster, dual oxidase (Duox kills pathogenic microbes by generating the microbicidal reactive oxygen species (ROS, hypochlorous acid (HOCl in response to bacterially excreted uracil. The physiological function of enzymatically generated HOCl in the gut is, however, unknown aside from its anti-microbial activity. Drosophila TRPA1 is an evolutionarily conserved receptor for reactive chemicals like HOCl, but a role for this molecule in mediating responses to gut microbial content has not been described. Here we identify a molecular mechanism through which bacteria-produced uracil facilitates pathogen-clearing defecation. Ingestion of uracil increases defecation frequency, requiring the Duox pathway and TrpA1. The TrpA1(A transcript spliced with exon10b (TrpA1(A10b that is present in a subset of midgut enteroendocrine cells (EECs is critical for uracil-dependent defecation. TRPA1(A10b heterologously expressed in Xenopus oocytes is an excellent HOCl receptor characterized with elevated sensitivity and fast activation kinetics of macroscopic HOCl-evoked currents compared to those of the alternative TRPA1(A10a isoform. Consistent with TrpA1's role in defecation, uracil-excreting Erwinia carotovora showed higher persistence in TrpA1-deficient guts. Taken together, our results propose that the uracil/Duox pathway promotes bacteria expulsion from the gut through the HOCl-sensitive receptor, TRPA1(A10b, thereby minimizing the chances that bacteria adapt to survive host defense systems.

Although 30-50% of constipated patients exhibit dyssynergia, an optimal method of diagnosis is unclear. Recently, consensus criteria have been proposed but their utility is unknown. To examine the diagnostic yield of colorectal tests, reproducibility of manometry and utility of Rome II criteria. A total of 100 patients with difficult defecation were prospectively evaluated with anorectal manometry, balloon expulsion, colonic transit and defecography. Fifty-three patients had repeat manometry. During attempted defecation, 30 showed normal and 70 one of three abnormal manometric patterns. Forty-six patients fulfilled Rome criteria and showed paradoxical anal contraction (type I) or impaired anal relaxation (type III) with adequate propulsion. However, 24 (34%) showed impaired propulsion (type II). Forty-five (64%) had slow transit, 42 (60%) impaired balloon expulsion and 26 (37%) abnormal defecography. Defecography provided no additional discriminant utility. Evidence of dyssynergia was reproducible in 51 of 53 patients. Symptoms alone could not differentiate dyssynergic subtypes or patients. Dyssynergic patients exhibited three patterns that were reproducible: paradoxical contraction, impaired propulsion and impaired relaxation. Although useful, Rome II criteria may be insufficient to identify or subclassify dyssynergic defecation. Symptoms together with abnormal manometry, abnormal balloon expulsion or colonic marker retention are necessary to optimally identify patients with difficult defecation.

Sinusoidal obstruction syndrome (SOS) is a life-threatening complication generally occurring after hematopoietic stem cell transplantation. SOS after standard dose chemotherapy in malignancies is rare. Between the year 1995 and 2016, 414 patients were diagnosed with acute lymphoblastic leukemia and 113 patients were diagnosed with Wilms tumor in our institution. Among these patients, 4 patients with acute lymphoblastic leukemia (0.96%) and 2 patients with Wilms tumor (1.7%) developed SOS during treatment. SOS behaves like a local disseminated intravascular coagulation. Defibrotide has proved to be effective in SOS. In this article, we report our experience with defibrotide in SOS.

To present a rare anomaly consisting of uterus didelphys, longitudinal vaginal septum, obstructed hemivagina with pyocolpos, fistula to the open vaginal canal, and ipsilateral renal agenesis, referred as Herlyn-Werner-Wunderlich syndrome (HWWS). A 14-year-old girl with recurring purulent vaginal discharge lasting for a few months. Preoperative examination revealed one vaginal canal with one cervical opening on the right side. There was a fistula leading from the obstructed vaginal canal to the left vagina. Intravaginal ultrasound examination demonstrated a longitudinal vaginal septum and a closed pyocolpos on the right side. The longitudinal vaginal septum was excised by way of electrocauterization under direct vision. HWWS should be considered in the differential diagnosis in patients with uterus didelphys and unusual symptoms such as pyocolpos and vaginal discharge.

Obstructive sleep apnoea (OSA) is a relatively common disorder, in developed country with prevalence estimated to lie between 2 and 4% in adult population. The diagnosis of this syndrome is made on the basis of characteristic clinical features and the results of nocturnal polysomnography. There is no data concerning the OSA in developing country. It is therefore of interest to determine the clinic and polysomnographic profile of this disease and to landmark factors correlated with severity in our country. This was achieved by studying a set of 63 OSA. The mean of age was 53 + 13 years with sex ratio 1. The means of Epworth sleepiness scale score, BMI and Apnoea/Hypopnoea index (AHI) were respectively 16 + 4, 38.8 + 7 kg/m2 and 51.7 + 28.6. 44% of patients have OSA severe with IAH > 50/h. Arousal index and desaturation index were respectively 36.4 + 21.7 and 49 + 26. Trial of continuous positive airway pressure (CPAP) therapy was proposed first to 40 patients, 17 were able to use CPAP.

A 60-year-old man was admitted to our hospital because of a persistent fever with enlargement of multiple lymph nodes in the mediastinum and around the pancreatic head. He was diagnosed with tuberculosis and human immunodeficiency virus infection. We started antiretroviral therapy three weeks after the initiation of anti-tuberculous therapy. Two weeks later, jaundice appeared with dilatation of the biliary tract due to further enlargement of the lymph nodes, which seemed to be immune reconstitution inflammatory syndrome (IRIS). The administration of corticosteroids resolved the obstructive jaundice without surgical treatment or endoscopic drainage. Obstructive jaundice caused by IRIS should first be treated with corticosteroids before invasive treatment.

Full Text Available Diarrheal diseases account for 7% of deaths in children under five years of age in Tanzania. Improving sanitation is an essential step towards reducing these deaths. This secondary analysis examined rural Tanzanian households’ sanitation behaviors and attitudes in order to identify barriers and drivers to latrine adoption. The analysis was conducted using results from a cross-sectional study of 1000 households in five rural districts of Tanzania. Motivating factors, perceptions, and constraints surrounding open defecation and latrine adoption were assessed using behavioral change theory. Results showed a significant association between use of improved sanitation and satisfaction with current sanitation facility (OR: 5.91; CI: 2.95–11.85; p = 0.008. Livestock-keeping was strongly associated with practicing open defecation (OR: 0.22; CI 0.063–0.75; p < 0.001. Of the 93 total households that practiced open defecation, 79 (85% were dissatisfied with the practice, 62 (67% had plans to build a latrine and 17 (18% had started saving for a latrine. Among households that planned to build a latrine, health was the primary reason stated (60%. The inability to pay for upgrading sanitation infrastructure was commonly reported among the households. Future efforts should consider methods to reduce costs and ease payments for households to upgrade sanitation infrastructure. Messages to increase demand for latrine adoption in rural Tanzania should integrate themes of privacy, safety, prestige and health. Findings indicate a need for lower cost sanitation options and financing strategies to increase household ability to adopt sanitation facilities.

To compare the clinical efficacies of two surgical procedures for hemorrhoid rectal prolapse with outlet obstruction-induced constipation. One hundred eight inpatients who underwent surgery for outlet obstructive constipation caused by internal rectal prolapse and circumferential hemorrhoids at the First Affiliated Hospital of Xinjiang Medical University from June 2012 to June 2013 were prospectively included in the study. The patients with rectal prolapse hemorrhoids with outlet obstruction-induced constipation were randomly divided into two groups to undergo either a procedure for prolapse and hemorrhoids (PPH) (n = 54) or conventional surgery (n = 54; control group). Short-term (operative time, postoperative hospital stay, postoperative urinary retention, postoperative perianal edema, and postoperative pain) and long-term (postoperative anal stenosis, postoperative sensory anal incontinence, postoperative recurrence, and postoperative difficulty in defecation) clinical effects were compared between the two groups. The short- and long-term efficacies of the two procedures were determined. In terms of short-term clinical effects, operative time and postoperative hospital stay were significantly shorter in the PPH group than in the control group (24.36 ± 5.16 min vs 44.27 ± 6.57 min, 2.1 ± 1.4 d vs 3.6 ± 2.3 d, both P hemorrhoids.

Full Text Available A large number of predisposing factors (obesity, nasal obstruction, adenoid hypertrophy, macroglossia, etc. are reported to be associated with obstructive sleep apnea syndrome (OUAS. In addition to these factors, the large goiter and hypothyroidism were reported to be associated with OSAS as well. However, this relationship could not yet be fully demonstrated. In our case related to plonjon goiter, we wanted to show the effect of hyroidectomy to OSAS and #8211;if there is- and the relationship between pressure and OSAS. Two years ago, a 72-year-old female with BMI: 26.8 kg/m2 patient was admitted to our clinic with complaints of respiratory standstill during sleep, snoring, morning headaches and drowsiness during daylight. In the chest X-ray, chest computed tomography and ultrasonography applied to the patient, it was detected that the trachea was deviated to the left due to euthyroid plonjon goiter and severe OSAS and polisomnografisi (PSG was diagnosed for the patient. The patients apnea-hypopnea index (AHI was measured 63.1/h. With the aim of treatment, in 7cm H2O pressure, nasal continuous positive airway pressure (nCPAP was applied to the patient and AHI decreased to the level of 11.4/h. Thyroidectomy was performed one month after the diagnosis. AHI was found 34.8 /h on the PSG applied for the purpose of 8 week-postoperative control. There were recovery on the levels of total sleep time, AHI, obstructive apnea index, hypopnea index, average desaturation index, stage 3 and REM as 16%, 44.8%, 84.7%, 19%, 38.3%, 52.4% and 28% respectively when compared the preoperative term with and postoperative term. It was demonstrated that there was no change of the in the degree of OSAS after thyroidectomy but only some partial improvement in the OSAS. The conclusion that there may be some improvements in nCPAP pressures after thyroidectomy and nCPAP treatment should not be stopped was reached. Also, it should be kept in mind that patients who apply to

The role of gender and menopause in obstructive sleep apnoea is well known; however, no study has reported the impact of gender on the clinical presentation and the nocturnal respiratory events in patients with obesity hypoventilation syndrome. Therefore, this study prospectively evaluated differences in the clinical characteristics of women and men with obesity hypoventilation syndrome in a large cohort of patients with obstructive sleep apnoea. During the study period, a total of 1973 patients were referred to the sleep clinic with clinical suspicion of obstructive sleep apnoea. All patients underwent overnight polysomnography, during which time spirometry, arterial blood samples and thyroid tests were routinely obtained. Among 1973 consecutive patients, 1693 (617 women) were diagnosed with obstructive sleep apnoea, among whom 144 suffered from obesity hypoventilation syndrome (96 women). The prevalence of obesity hypoventilation syndrome among women and men was 15.6% and 4.5%, respectively (P obesity hypoventilation syndrome were significantly older than men with obesity hypoventilation syndrome (61.5 ± 11.9 years versus 49.1 ± 12.5 years, P differences between genders regarding symptoms, body mass index, spirometric data or daytime PaCO2 , women with obesity hypoventilation syndrome suffered significantly more from hypertension, diabetes and hypothyroidism. The prevalence of obesity hypoventilation syndrome was higher in post-menopausal (21%) compared with pre-menopausal (5.3%) women (P obesity hypoventilation syndrome. In conclusion, this study reported that among subjects referred to the sleep disorders clinic for evaluation of obstructive sleep apnoea, obesity hypoventilation syndrome is more prevalent in women than men, and that women with obesity hypoventilation syndrome suffer from significantly more co-morbidities.

The morbidity and mortality of obstructive sleep apnea-hypopnea syndrome (OSAHS) are regarded as consequences of its adverse effects on the cardiovascular system. Chronic intermittent hypoxia (CIH) induced by OSAHS can result in vascular endothelial injury, thus promoting development of atherosclerosis (AS). Studies have shown that CIH is an independent risk factor for the occurrence and development of AS, but the underlying mechanism remains unclear. Here, we review clinical and fundamental ...

To evaluate the usefulness of flexible covered stent in the treatment of acute colorectal obstruction secondary to colorectal carcinoma. Materials and Methods : Flexible covered stents were placed in 11 patients with clinical and radiologic signs of acute colonic obstruction secondary to colorectal carcinoma. The purposes of stent insertion were pre-operative bowel preparation in seven patients and palliative treatment in four. A fistula was present in two;in one this was between the proximal jejunum and colon, and the other was rectovaginal. The usefulness of stent insertion for the purpose of preoperative bowel preparation was evaluated according to the feasibility and status of bowel preparation, as decided by the operator. Palliative treatment for the relief of symptoms of acute bowel obstruction was evaluated according to the number and amount of defecation,bowel dilatation in simple abdomen radiography, and the presence of complications. Results : Bowel preparation for the purpose of preoperative bowel cleansing was easy in seven patients;the fecal materials remaining in the colon presented no problems during surgery. In one of four patients palliative treatment involved a colostomy;this was due to recurrent stent obstruction by fecal materials after three months, and in two other patients there was stent obstruction after two and five months, respectively. The stent in one of four patients who underwent palliative treatment was removed because of stent migration three days after insertion;the stents in two patients with fistulas covered the fistulas successfully. Complications after stent insertion were anal pain in three patients, anal bleeding in three and stent migration in one. Conclusion : The flexible covered stent was an effective device for the relief of acute colonic obstruction secondary to malignant rectosigmoid neoplasia. It allowed for single-stage operation and covered the fistula. We believe however that for further evaluation of the

Full Text Available Objective: To report a case of corneal neovascularization with secondary lipid keratopathy in a patient treated with continuous positive airway pressure (CPAP for obstructive sleep apnea-hypopnea syndrome (OSAHS. Case Report: A 49-year-old male had been diagnosed with obstructive sleep apnea syndrome 10 years ago and has been treated with the application of a CPAP machine during night sleep ever since. For the past year, the patient had been complaining for ocular irritation and excessive tearing of the left eye on awakening. Slit-lamp biomicroscopy revealed the presence of neovascularization and lipid exudation in the inferior third of the cornea of the left eye. Ocular patching during night sleep resulted in recession of the reported symptoms and shrinkage of the neovascularization, while the area of lipid exudation ceased to enlarge. Conclusion: To the best of our knowledge, this is the first report of corneal neovascularization in a patient using a CPAP machine for OSAHS.

Children with functional constipation often state an inability to sense an urge to defecate and/or inability to feel incontinence. We used colon manometry to assess whether there was a sensory abnormality in patients who denied sensation. A physician observed all of the colon manometries in the preceding 20 years, and included behavioral observations in the procedure reports. We reviewed the charts of these patients. Of 150 subjects with normal manometry and a diagnosis of functional constipation, 56 volunteered that they had no urge to defecate or complained of abdominal pain. For all who denied sensation, the first high-amplitude propagating colonic contraction (HAPC) was associated with retentive posturing and facial grimaces. When queried, all reported they felt nothing. The examiner explained the HAPC was causing pain, and informed the child that the pain would resolve if they defecated. With subsequent HAPCs, every patient acknowledged an urge to defecate and successfully defecated. Most agreed that a similar pain sensation was present daily, but was misinterpreted to be abdominal pain. Colon manometry may be useful not only for objective findings to discriminate neuromuscular disease from functional symptoms but also to understand psychological issues and aid in helping the child and family understand the maladaptive behaviors in functional constipation.

Sleep. 5: Driving and automobile crashes in patients with obstructive sleep apnoea/hypopnoea syndrome.

Driving is a complex task involving distinct cognitive, perceptual, motor, and decision making skills. After placing the vehicle on the road, the driver must constantly survey the ever changing roadway environment to keep the vehicle in the lane and moving at an appropriate safe speed. This surveillance involves two distinct visual tasks: estimating and responding to the oncoming curvature and controlling lane position. Driving is therefore a divided attention task involving speed and lane control as well as monitoring. To do this in a safe manner requires careful attention and alertness which can be problematic for patients with obstructive sleep apnoea/hypopnoea syndrome (OSAHS) or other sleep disorders.

Impact of Facial Conformation on Canine Health: Brachycephalic Obstructive Airway Syndrome

2015-01-01

The domestic dog may be the most morphologically diverse terrestrial mammalian species known to man; pedigree dogs are artificially selected for extreme aesthetics dictated by formal Breed Standards, and breed-related disorders linked to conformation are ubiquitous and diverse. Brachycephaly–foreshortening of the facial skeleton–is a discrete mutation that has been selected for in many popular dog breeds e.g. the Bulldog, Pug, and French Bulldog. A chronic, debilitating respiratory syndrome, whereby soft tissue blocks the airways, predominantly affects dogs with this conformation, and thus is labelled Brachycephalic Obstructive Airway Syndrome (BOAS). Despite the name of the syndrome, scientific evidence quantitatively linking brachycephaly with BOAS is lacking, but it could aid efforts to select for healthier conformations. Here we show, in (1) an exploratory study of 700 dogs of diverse breeds and conformations, and (2) a confirmatory study of 154 brachycephalic dogs, that BOAS risk increases sharply in a non-linear manner as relative muzzle length shortens. BOAS only occurred in dogs whose muzzles comprised less than half their cranial lengths. Thicker neck girths also increased BOAS risk in both populations: a risk factor for human sleep apnoea and not previously realised in dogs; and obesity was found to further increase BOAS risk. This study provides evidence that breeding for brachycephaly leads to an increased risk of BOAS in dogs, with risk increasing as the morphology becomes more exaggerated. As such, dog breeders and buyers should be aware of this risk when selecting dogs, and breeding organisations should actively discourage exaggeration of this high-risk conformation in breed standards and the show ring.

The application value of small intestine decompression combined with oral feeding in the middle and late period of malignant small bowel obstruction was examined. A total of 22 patients with advanced malignant small bowel obstruction were included in the present study. An ileus tube was inserted via the nose under fluoroscopy into the obstructed small intestine of each patient. At the same time, the insertion depth the of the catheter was adjusted. When the catheter was blocked, small bowel selective angiography was performed to determine the location and cause of the obstruction and the extent of the obstruction, and to determine the length of the small intestine in the site of obstruction, and to select the variety and tolerance of enteral nutrition. We observed the decompression tube flow and ease of intestinal obstruction. In total, 20 patients were treated with oral enteral nutrition after abdominal distension, and 22 cases were treated by the nose to observe the drainage and the relief of intestinal obstruction. The distal end of the catheter was placed in a predetermined position. The symptoms of intestinal obstruction were relieved 1-4 days after decompression. The 22 patients with selective angiography of the small intestine showed positive X-ray signs: 18 patients with oral enteral nutrition therapy had improved the nutritional situation 2 weeks later. In 12 cases, where there was anal defecation exhaust, 2 had transient removal of intestinal obstruction catheter. In conclusion, this comprehensive treatment based on small intestine decompression combined with enteral nutrition is expected to become a new therapeutic approach and method for the treatment of patients with advanced tumor small bowel obstruction.

Non-Obstructive Middle Lobe Syndrome: An Unusual Cause of Recurrent Pneumonia in an Elderly Woman

2017-11-01

Full Text Available An 84-year-old woman had five episodes of pneumonia in 4 months. Despite extensive comorbidities and advanced age, her health status was good and the recurrence seemed unjustified. Exhaustive background investigation revealed 14 episodes of right-sided pneumonias during the 3 previous years and an inconclusive investigation with CT of the thorax and bronchofibroscopy, despite some fibrotic and atelectasic alterations in the right middle lobe. A new right-sided x-ray showed a wedge-shaped density extending anteriorly and inferiorly from the hilum, and CT of the thorax revealed aggravated middle lobe abnormalities with thickening of the bronchial wall and segment atelectasis, without any visible airway obstruction. After extensive work-up had excluded other causes of recurrent pneumonia and immunodeficiency, a non-obstructive middle lobe syndrome (MLS was deemed responsible for the repeated episodes of pneumonia. MLS is characterised by chronic hypoventilation and atelectasis of the middle lobe, facilitating secretion accumulation, chronic inflammation and repeated infection. After treatment with bronchodilators and immunostimulants was initiated, the patient experienced no recurrences for several months.

What are the anatomic variants (and their frequencies) of double uterus, obstructed hemivagina and ipsilateral renal agenesis? Most cases examined (72.4%) were of the classic anatomic variant of the Herlyn-Werner-Wunderlich syndrome (with didelphys uterus, obstructed hemivagina and ipsilateral renal agenesis) but the 27.6% of cases are of a rare variant of the syndrome (with uterus septum or cervical agenesis), showing relevant clinical and surgical implications. The extreme variability of anatomic structures involved in this syndrome (both uterus, cervico-vaginal and renal anomalies) is well known, even if a complete and uniform analysis of all its heterogeneous presentations in a large series is lacking. This is a retrospective study with 87 patients referred to our third level referral center between 1981 and 2011. We analyzed the laparoscopic and chart records of 87 women, who referred to our institute with double uterus, unilateral cervico-vaginal obstruction and ipsilateral renal anomalies. Sixty-three of 87 patients had the more classic variant of didelphys uterus with obstructed hemivagina; 10/87 patients had septate bicollis uterus with obstructed hemivagina; 9/87 patients had bicornuate bicollis uterus with obstructed hemivagina; 4/87 patients had didelphys uterus with unilateral cervical atresia; 1/87 patients had bicornuate uterus with one septate cervix and unilateral obstructed hemivagina. This is a retrospective study with a long enrolling period (30 years). New insights in the anatomic variants of this rare syndrome with their relevant surgical implications.

Asthma and chronic obstructive pulmonary disease (COPD) are highly prevalent chronic diseases in the general population. Both are characterized by similar mechanisms: airway inflammation, airway obstruction, and airway hyperresponsiveness. However, the distinction between the two obstructive diseases is not always clear. Multiple epidemiological studies demonstrate that in elderly people with obstructive airway disease, as many as half or more may have overlapping diagnoses of asthma and COPD...

Excessive daytime sleepiness is a common symptom in obstructive sleep apnea (OSA). Previous studies have showed that excessive daytime sleepiness is associated with some individual components of metabolic syndrome. We performed a large cross-sectional study to explore the relationship between excessive daytime sleepiness and metabolic syndrome in male OSA patients. A total of 2241 suspected male OSA patients were consecutively recruited from 2007 to 2013. Subjective daytime sleepiness was assessed using the Epworth sleepiness scale. Anthropometric, metabolic, and polysomnographic parameters were measured. Metabolic score was used to evaluate the severity of metabolic syndrome. Among the male OSA patients, most metabolic parameters varied by excessive daytime sleepiness. In the severe group, male OSA patients with excessive daytime sleepiness were more obese, with higher blood pressure, more severe insulin resistance and dyslipidemia than non-sleepy patients. Patients with metabolic syndrome also had a higher prevalence of excessive daytime sleepiness and scored higher on the Epworth sleepiness scale. Excessive daytime sleepiness was independently associated with an increased risk of metabolic syndrome (odds ratio =1.242, 95% confidence interval: 1.019-1.512). No substantial interaction was observed between excessive daytime sleepiness and OSA/ obesity. Excessive daytime sleepiness was related to metabolic disorders and independently associated with an increased risk of metabolic syndrome in men with OSA. Excessive daytime sleepiness should be taken into consideration for OSA patients, as it may be a simple and useful clinical indicator for evaluating the risk of metabolic syndrome.

We reviewed the sonographic and MRI findings of tracheolaryngeal obstruction in the fetus. Conditions that can cause tracheolaryngeal obstruction include extrinsic causes such as lymphatic malformation, cervical teratoma and vascular rings and intrinsic causes such as congenital high airway obstruction syndrome (CHAOS). Accurate distinction of these conditions by sonography or MRI can help facilitate parental counseling and management, including the decision to utilize the ex utero intrapartum treatment (EXIT) procedure.

Children with Down syndrome are described as having macroglossia as well as midface hypoplasia. We reviewed anatomic parameters on MRI to determine whether adolescents with Down syndrome have true macroglossia or relatively large tongues compared to the small size of their oral cavity. This has implications for the treatment of obstructive sleep apnea, which occurs at a relatively high rate among patients with Down syndrome. To determine whether adolescents with Down syndrome have relative rather than true macroglossia. On sagittal and axial MR images, parameters for tongue size (area in sagittal midline), the bony craniofacial confines of the retroglossal pharynx (distance between the mandibular rami and distance between the posterior aspect of the mental mandible and the anterior aspect of the spine), and the size of the tongue relative to the craniofacial bony parameters [tongue area/(transverse diameter x anterior-to-posterior diameter)] were compared between 16 patients with Down syndrome and 16 age- and gender-matched controls. The tongue area was significantly smaller in patients with Down syndrome (2,432 mm{sup 2}) than in the control patients (2,767 mm{sup 2}; P=0.02). The craniofacial bony parameters were also smaller in patients with Down syndrome than in the controls (left-right 69.8 vs. 80.1 mm, P<0.001; anterior-posterior 64.2 vs. 74.9 mm, P<0.001). However, the size of the tongue relative to the craniofacial parameters was larger in the patients with Down syndrome (0.54) than in the controls (0.46; P<0.001). Children with Down syndrome do not have true macroglossia but have relatively large tongues compared to the bony confines of the oral cavity. (orig.)

Full Text Available Introduction: Phenotypic overlap between the two main chronic airway pulmonary diseases, asthma and chronic obstructive pulmonary disease (COPD, has been the subject of debate for decades, and recently the nomenclature of asthma-COPD overlap syndrome (ACOS was adopted for this condition. The definition of this entity in the literature is, however, very heterogeneous, it is therefore important to define how it applies to Portugal. Methods: A literature review of ACOS was made in a first phase resulting in the drawing up of a document that was later submitted for discussion among a panel of chronic lung diseases experts, resulting in reflexions about diagnosis, treatment and clinical guidance for ACOS patients. Results: There was a consensus among the experts that the diagnosis of ACOS should be considered in the concomitant presence of: clinical manifestations characteristic of both asthma and COPD, persistent airway obstruction (post-bronchodilator FEV1/FVC 300 eosinophils/μL or >5% of leukocytes and previous history of atopy should also be considered. The recommended first line pharmacological treatment in these patients is the ICS/LABA association; if symptomatic control is not achieved or in case of clinical severity, triple therapy with ICS/LABA/LAMA may be used. An effective control of the exposure to risk factors, vaccination, respiratory rehabilitation and treatment of comorbidities is also important. Conclusions: The creation of initial guidelines on ACOS, which can be applied in the Portuguese context, has an important role in the generation of a broad nationwide consensus. This will give, in the near future, a far better clinical, functional and epidemiological characterization of ACOS patients, with the ultimate goal of achieving better therapeutic guidance.

Japan is an aging society, and the number of elderly patients with asthma and chronic obstructive pulmonary disease (COPD) is consequently increasing, with an estimated incidence of approximately 5 million. In 2014, asthma-COPD overlap syndrome (ACOS) was defined by a joint project of Global Initiative for Asthma (GINA) committee and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) committee. The main aims of this consensus-based document are to assist clinicians, especially those in primary care or nonpulmonary specialties. In this article, we discussed parameters to differentiate asthma and COPD in elderly patients and showed prevalence, clinical features and treatment of ACOS on the basis of the guidelines of GINA and GOLD. Furthermore, we showed also referral for specialized investigations.

Hepatic sinusoidal obstruction syndrome (SOS) is a life-threatening syndrome that generally occurs as a complication after hematopoietic stem cell transplantation or, less commonly, after conventional chemotherapy. Regarding SOS in rhabdomyosarcoma patients who received conventional chemotherapy, the doses of chemotherapeutic agents are associated with the development of SOS. Several cases of SOS in rhabdomyosarcoma patients after receiving chemotherapy with escalated doses of cyclophosphamide have been reported. Here, we report on a 9-year-old female with rhabdomyosarcoma who developed severe SOS after receiving chemotherapy consisting of vincristine, actinomycin-D, and a moderate dose of cyclophosphamide. She was treated successfully with defibrotide without sequelae to the liver.

To investigate the relationship of IL-1β and IL-6 cytokine gene polymorphisms with obstructive sleep apnea syndrome (OSAS) in 61 patients admitted to the neurology clinic in Kafkas University Hospital with insomnia problem who were diagnosed with OSAS in sleeping labs, and 80 healthy subjects not associated with the syndrome. METHODS :Blood samples were taken to isolate DNA from patients diagnosed with OSAS based on polysomnography results and healthy controls. DNA amplification of the genes was performed with PCR. Amplification products were cut with the restriction enzymes in order to determine IL-1 gene (TaqI) and IL-6 gene (Lwel) polymorphisms. The cut DNA fragments were carried out in agarose gel electrophoresis, and RFLP analysis was performed by utilizing the images with gel imaging system. PCR products were sequenced with an Applied Biosystems Automated Sequencer. Polymorphic changes were observed for IL-1β gene in 26 of 62 patients (41.9%), and 16 of the 80 (25.8%) in the control group. The incidence of polymorphic changes in IL-6 gene was in seen in seven (of the 62 patients) (11.3%), and in the 16 (20%) controls. The findings on the genomic level in OSAS may provide an important contribution to diagnosis of obstructive sleep apnea syndrome in clinical practice, as well as it helps to obtain the results easily about environmental and genetic interaction of OSAS patients.

Full Text Available Introduction. Left ventricular outflow obstruction might be part of the pathophysiological mechanism of Tako-tsubo cardiomyopathy. This obstruction can be masked by Tako-tsubo cardiomyopathy and diagnosed only by followup. Case Presentation. A 70-year-old female presented with Tako-tsubo cardiomyopathy and masked obstructive hypertrophic cardiomyopathy at presentation. Conclusion. Tako-tsubo cardiomyopathy typically presents like an acute MI and is characterized by severe, but transient, regional left ventricular systolic dysfunction. Prompt evaluation of the coronary status is, therefore, mandatory. The prognosis under medical treatment of heart failure symptoms and watchful waiting is favourable. Previous studies showed that LVOT obstruction might be part of the pathophysiological mechanism of TCM. This paper supports this theory. However, TCM may also mask any preexisting LVOT obstruction.

Full Text Available Abstract Introduction We present the case of a patient with colon cancer who, while receiving bevacizumab, developed sinusoidal obstruction syndrome (veno-occlusive disease (SOSVOD. Certain antitumour agents such as 6-mercaptopurine and 6-thioguanine have also been reported to initiate hepatic SOSVOD in isolated cases. There have been no reports so far correlating bevacizumab with SOSVOD. Case presentation A 77-year-old man was being treated with oxaliplatin and a modified de Gramont regimen of 5-fluorouracil for metastatic colon cancer. Bevacizumab (7.5 mg/kg was added from the seventh cycle onwards. Protracted neutropenia and thrombocytopenia led to discontinuation of oxaliplatin after the ninth cycle. A computed tomography scan showed complete response and bevacizumab was continued for another 3 months, after which time the patient developed right hypochondrial pain, transudative ascites, splenomegaly and abnormal liver function tests. Upper gastrointestinal endoscopy showed oesophageal varices. Liver biopsy showed features considered to be consistent with SOSVOD. Bevacizumab was stopped and a policy of watchful waiting was adopted. He tolerated the acute damage to his liver and subsequently the ascites resolved and liver function tests normalised. Conclusion We need to be aware that bevacizumab can cause sinusoidal obstruction syndrome (veno-occlusive disease and that the occurrence of ascites should not be attributed to progressive disease without appropriate evaluation.

Solitary rectal ulcer syndrome (SRUS) is often resistant to medical and surgical treatment. This study assessed the effect of biofeedback in decreasing the symptoms and the healing of endoscopic signs in SRUS patients. Before starting the treatment, endoscopy and colorectal manometry was performed to evaluate dyssynergic defecation. Patients were followed every four weeks, and during each visit their response to treatment was evaluated regarding to manometry pattern. After at least 50% improvement in manometry parameters, recipients underwent rectosigmoidoscopy. Endoscopic response to biofeedback treatment and clinical symptoms were investigated. Duration of symptoms was 43.11±36.42 months in responder and 63.9 ± 45.74 months in non-responder group (P=0.22). There were more ulcers in non-responder group than responder group (1.50 ±0.71 versus 1.33±- 0.71 before and 1.30 ± 0.95 versus 0.67 ±0.50 after biofeedback), although the difference was not significant (P=0.604, 0.10 respectively). The most prevalent symptoms were constipation (79%), rectal bleeding (68%) and anorectal pain (53%). The most notable improvement in symptoms after biofeedback occured in abdominal pain and incomplete evacuation, and the least was seen in mucosal discharge and toilet waiting as shown in the bar chart. Endoscopic cure was observed in 4 of 10 patients of the non-responder group while 8 patients in responder group experienced endoscopic improvement. It seems that biofeedback has significant effect for pathophysiologic symptoms such as incomplete evacuation and obstructive defecation. Improvement of clinical symptoms does not mean endoscopic cure; so to demonstrate remission the patients have to go under rectosigmoidoscopy.

The initial signs of hepatic sinusoidal obstruction syndrome (HSOS) can be challenging to recognize in children, especially outside the hematopoietic stem cell transplantation setting. To assist clinicians to promptly identify HSOS, the European Society for Blood and Marrow Transplantation has proposed pediatric HSOS diagnostic criteria which emphasize unexplained consumptive and transfusion-refractory thrombocytopenia. To highlight the importance of these "bellwether" early signs of HSOS and the efficacy of pre-emptive treatment with defibrotide, we describe the case of a child with a right 11th rib primitive neuroectodermal tumor who developed HSOS following focal radiotherapy and actinomycin-D treatment. © 2018 The Authors.

Full Text Available Introduction. Obstructive sleep apnea syndrome (OSAS is a disease with increasing prevalence nowadays, being associated with multiple cardiovascular diseases, such as arterial hypertension. The objective of the study was to evaluate the effect of continuous positive airway pressure (CPAP on blood pressure values. Materials and methods. We performed a prospective interventional study on 52 patients with obstructive sleep apnea syndrome. The patients were divided into 2 groups: Group A (who received both pharmacological and CPAP treatment and Group B (who received only pharmacological treatment, and were followed up at 3 and 6 months. The statistical analysis was made with SPSS and Microsoft Excel. At the same time, using the surrogate marker –RDW, we tried to evaluate the persistence of systemic inflammation, knowing that OSAS is associated with inflammation. Results. The systolic blood pressure values decreased at 6 months in all OSAS patients who have used CPAP, including patients with normal values of blood pressure. At the same time, the lack of OSAS treatment led to increased values of blood pressure by approximately 10 mmHg. We noticed a link between RDW, age and blood pressure values, respectively the increase of RDW and age may result in an increase in blood pressure. Conclusions. The OSAS treatment can decrease the blood pressure values. A higher RDW may be considered a negative prognostic factor for these patients, reflecting the role of systemic inflammation in the appearance of cardiovascular disorders.

Asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) is defined as having both features of asthma and COPD, which are airway hyper-responsiveness and incompletely reversible airway obstruction. However, socioeconomic impact of ACOS have not been well appreciated. Adults with available wheezing history and acceptable spirometry were selected from the fourth Korean National Health and Nutrition Examination Survey (KNHANES IV) in 2007-2009. Their data were merged with the Korean National Health Insurance claim data. 'Asthma group' was defined as having self-reported wheezing history and FEV 1 /FVC ≥0.7, 'COPD group' was defined as having FEV 1 /FVC COPD, 8.4%; asthma, 5.8% and NAD, 83.6%. Total length of healthcare utilization and medical costs of ACOS group was the top among four groups (PCOPD group (P=0.025). Multiple linear regression analyses showed that ACOS group (β=12.63, P<0.001) and asthma group (β=6.14, P<0.001) were significantly associated with longer duration of healthcare utilization and ACOS group (β=350,475.88, P=0.008) and asthma group (β=386,876.81, P<0.001) were associated with higher medical costs. This study demonstrated that ACOS independently influences healthcare utilization after adjusting several factors. In order to utilize limited medical resources efficiently, it may be necessary to find and manage ACOS patients.

How much crude oil can zooplankton ingest? Estimating the quantity of dispersed crude oil defecated by planktonic copepods

Almeda, Rodrigo; Connelly, Tara L.; Buskey, Edward J.

2016-01-01

We investigated and quantified defecation rates of crude oil by 3 species of marine planktonic copepods (Temora turbinata, Acartia tonsa, and Parvocalanus crassirostris) and a natural copepod assemblage after exposure to mechanically or chemically dispersed crude oil. Between 88 and 100% of the analyzed fecal pellets from three species of copepods and a natural copepod assemblage exposed for 48 h to physically or chemically dispersed light crude oil contained crude oil droplets. Crude oil droplets inside fecal pellets were smaller (median diameter: 2.4–3.5 μm) than droplets in the physically and chemically dispersed oil emulsions (median diameter: 6.6 and 8.0 μm, respectively). This suggests that copepods can reject large crude oil droplets or that crude oil droplets are broken into smaller oil droplets before or during ingestion. Depending on the species and experimental treatments, crude oil defecation rates ranged from 5.3 to 245 ng-oil copepod"−"1 d"−"1, which represent a mean weight-specific defecation rate of 0.026 μg-oil μg-C_c_o_p_e_p_o_d"1 d"−"1. Considering a dispersed crude oil concentration commonly found in the water column after oil spills (1 μl L"−"1) and copepod abundances in high productive coastal areas, copepods may defecate ∼1.3–2.6 mg-oil m"−"3 d"−"1, which would represent ∼0.15%–0.30% of the total dispersed oil per day. Our results indicate that ingestion and subsequent defecation of crude oil by planktonic copepods has a small influence on the overall mass of oil spills in the short term, but may be quantitatively important in the flux of oil from surface water to sediments and in the transfer of low-solubility, toxic petroleum hydrocarbons into food webs after crude oil spills in the sea. - Highlights: • Copepods exposed to dispersed crude oil produced fecal pellets contained numerous small oil droplets (2.4 to 3.5 µm). • Copepods could reject large oil droplets or oil droplets are broken into

Snoring and the obstructive sleep apnea syndrome are common and chronic ailments with potentially serious medical complications. There are several accepted treatments, but these can be uncomfortable, inconvenient, and expensive. A number of alternative treatments have been reported to be beneficial in the treatment of obstructive sleep apnea and snoring. They are advertised in magazines, on the radio and television, and on the Internet. The lay press is reporting about the effectiveness of these treatments without the benefit of clinical trials or scientific studies. Among the therapies currently being promoted for the treatment of snoring and sleep apnea is biomagnetic therapy. Unlike many of the other treatments which have not undergone scientific evaluation, biomagnetic therapy has been evaluated in the past. In fact, the evaluation of biomagnetic therapy is one of the first controlled scientific investigations found in the literature. This report showed that magnet therapy had no medicinal value. Despite this clear evidence, magnetic therapy continues to be utilized today and currently is being promoted for the treatment of snoring and sleep apnea. At out Sleep Disorder Center, we have had the opportunity to evaluate a patient with severe obstructive sleep apnea both before and after treatment with magnetic therapy, as well as with conventional therapy. Our study clearly indicates there was no benefit from magnetic therapy in this case. While alternative therapy may be helpful in the treatment of certain medical conditions, extreme care must be exercised to prevent inappropriate treatment or undertreat-ment of significant medical problems. Close clinical follow-up and controlled studies are important in determining the effectiveness of therapies.

To review the efficacy and safety of defibrotide as well as its pharmacology, mechanism of action, pharmacokinetics (PK), drug-drug interactions, dosing, cost considerations, and place in therapy. A PubMed search was performed through August 2017 using the terms defibrotide, oligonucleotide, hepatic veno-occlusive disease (VOD), sinusoidal obstruction syndrome (SOS), and hematopoietic cell transplantation (HCT). Other data sources were from references of identified studies, review articles, and conference abstracts plus manufacturer product labeling and website, the Food and Drug Administration website, and clinicaltrials.gov. English-language trials that examined defibrotide's pharmacodynamics, mechanism, PK, efficacy, safety, dosing, and cost-effectiveness were included. Trials have confirmed the safety and efficacy of defibrotide for treatment of VOD/SOS in adult and pediatric HCT patients, with complete response rates and day +100 overall survival rates ranging from 25.5% to 76% and 35% to 64%, respectively. The British Committee for Standards in Haematology/British Society for Blood and Marrow Transplantation Guidelines recommend defibrotide prophylaxis in pediatric and adult HCT patients with risk factors for VOD/SOS; however, its prophylactic use in the United States is controversial. Although there are efficacy data to support this strategy, cost-effectiveness data have not shown it to be cost-effective. Defibrotide has manageable toxicities, with low rates of grade 3 to 4 adverse effects. Defibrotide is the first medication approved in the United States for the treatment of adults and children with hepatic VOD/SOS, with renal or pulmonary dysfunction following HCT. Data evaluating defibrotide for VOD/SOS prevention are conflicting and have not shown cost-effectiveness.

Obstructive sleep apnea syndrome has multifactorial causes. Although indications for surgery are evaluated by well-known diagnostic tests in the awake state, these do not always correlate with satisfactory surgical results. To undertake a systematic review on endoscopy during sleep, as one element of the diagnosis routine, aiming to identify upper airway obstruction sites in adult patients with OSAS. By means of electronic databases, a systematic review was performed of studies using drug-induced sleep endoscopy to identify obstruction sites in patients with OSAS. Ten articles were selected that demonstrated the importance of identifying multilevel obstruction, especially in relation to retrolingual and laryngeal collapse in OSAS. DISE is an additional method to reveal obstruction sites that have not been detected in awake patients. Copyright © 2015 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Relationship between aldosterone and the metabolic syndrome in patients with obstructive sleep apnea hypopnea syndrome: effect of continuous positive airway pressure treatment.

Directory of Open Access Journals (Sweden)

Antonia Barceló

Full Text Available BACKGROUND: Metabolic syndrome (MS occurs frequently in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS. We hypothesized that aldosterone levels are elevated in OSAHS and associated with the presence of MS. METHODS: We studied 66 patients with OSAHS (33 with MS and 33 without MS and 35 controls. The occurrence of the MS was analyzed according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III clinical criteria. Measurements of plasma renin activity (PRA, aldosterone, aldosterone:PRA ratio, creatinine, glucose, triglycerides, cholesterol and HDL cholesterol were obtained at baseline and after CPAP treatment. RESULTS: Aldosterone levels were associated with the severity of OSAHS and higher than controls (p = 0.046. Significant differences in aldosterone levels were detected between OSAHS patients with and without MS (p = 0.041. A significant reduction was observed in the aldosterone levels in patients under CPAP treatment (p = 0.012. CONCLUSION: This study shows that aldosterone levels are elevated in OSAHS in comparison to controls, and that CPAP therapy reduces aldosterone levels. It also shows that aldosterone levels are associated with the presence of metabolic syndrome, suggesting that aldosterone excess might predispose or aggravate the metabolic and cardiovascular complications of OSAHS. TRIAL REGISTRATION: The study is not a randomized controlled trial and was not registered.

Objective: To evaluate the efficiency and safety of intraluminal stent as a treatment of malignant obstruction of digestive tract and esophago-bronchial fistula. Methods: In total 71 patients suffered with malignant obstruction or esophago-bronchial fistula were treated with permanent nickel-titanium alloy, partially covered stents. All the procedures were performed under DSA guidance. Inserted via the oral anal access, the stents were placed at the sites of obstructions or the fistulas. Esophagogram or colonogram were done before and post the intervention. The clinical efficiency was assessed by function of swallowing or defecation in follow-up. Results: In 62 patients (96.9%), function of swallowing was restored after the stent was placed in upper digestive tract without drinking triggered coughing. Symptoms were immediately relieved after the stent was placed in sigmoid colon or rectum. Displacement of stents was seen in 2 cases (2.8%); restenosis in 2 (2.8%); hoarse voice was noted in 1 case (1.4%); intense thoracic pain was complained in 2 cases (2.8%); mild pain was noted in 12 cases (16.9%); and massive hemorrhage was complicated in 1 case (1.4%). All complications were successfully controlled after proper treatment. Conclusion: It is an effective, easy and safe method to treat malignant obstruction of digestive tract or esophago-bronchial fistula using partially covered nickel-titanium alloy stent. (authors)

Children with Down syndrome are at increased risk of obstructive sleep apnea (OSA). The aim of the study was to describe the management of OSA in a large cohort of children with Down syndrome. A retrospective analysis of sleep studies and consequent management was performed for all consecutive Down syndrome patients evaluated between September 2013 and April 2016. The data of 57 patients were analyzed: 51/53 had an interpretable overnight polygraphy and 4 the recording of nocturnal gas exchange. Mean age at baseline sleep study was 6.2 ± 5.9 years. Eighteen patients (32%) had prior upper airway surgery. Mean apnea-hypopnea index (AHI) was 14 ± 16 events/hr with 41 of the 51 (80%) patients having OSA with an AHI >1 event/hr and 20 patients (39%) having an AHI ≥10 events/hr. Consequently, eight patients (14%) had upper airway surgery. OSA improved in all patients except two who needed noninvasive respiratory support. Nineteen (33%) patients required noninvasive respiratory support. Mean age at noninvasive respiratory support initiation was 7 ± 7 years. On 11 patients with objective adherence data available, mean compliance at 2 ± 1 years of treatment was excellent with an average use per night of 8 hr46 ± 3 hr59 and 9 patients using the noninvasive respiratory support >4 hr/night. Noninvasive respiratory support was associated with an improvement of nocturnal gas exchange. The prevalence of OSA is high in Down syndrome. Upper airway surgery is not always able to correct OSA. Noninvasive respiratory support represents then an effective treatment for OSA and good compliance may be achieved in a majority of patients. © 2017 Wiley Periodicals, Inc.

Full Text Available The sustainable use of white-tailed deer in Mexico can only be performed in Management Units for the Conservation of Wildlife (UMA , for its acronym in Spanish , based on a management plan for legal operation. Among the methods for population estimate harvest rates, highlights fecal count groups, depending on the frequency at which a deer excretes daily, and whose values are estimated from captive specimens and tolerant observer, but considering subspecies and different from the northern Sinaloa conditions. Using these rates of defecation can lead to overharvesting. This research was conducted in the farmed deer of the indigenous ejido (Mayo-Yoreme ethnic group called “Los Capomos”, in the municipality of El Fuerte, Sinaloa, between October 2011 and May 2012, to estimate the rate of defecation counts from fecal groups, obtained from a confined deer population and in apparent equilibrium with its environment through adjustments to the model of Eberhardt and Van Etten. It was found that the lowest rate published defecation (12.7 deer fecal groups per day, the estimated population accounted for half of the known population, which would prevent excessive use of native deer in the wild. However, the pattern of random grouping of excreta in confinement, makes it advisable that it be used in conditions of freedom, since it presupposes the mathematical model used aggregate grouping patterns.

2011-01-01

Chronic perineal pain is the anorectal and perineal pain without underlying organic disease, anorectal or endopelvic, which has been excluded by careful physical examination, radiological and endoscopic investigations. A variety of neuromuscular disorders of the pelvic floor lead to the different pathological conditions such as anorectal incontinence, urinary incontinence and constipation of obstructed defecation, sexual dysfunction and pain syndromes. The most common functional disorders of the pelvic floor muscles, accompanied by perineal pain are levator ani syndrome, proctalgia fugax, myofascial syndrome and coccygodynia. In the diagnosis of these syndromes, contributing to a thorough history, physical examination, selected specialized investigations and the exclusion of organic disease with proctalgia is carried out. Accurate diagnosis of the syndromes helps in choosing an appropriate treatment and in avoiding unnecessary and ineffective surgical procedures, which often are performed in an attempt to alleviate the patient's symptoms.

Budd-Chiari syndrome occurs when venous outflow from the liver is obstructed. The obstruction may occur at any point from the hepatic venules to the left atrium. The syndrome most often occurs in patients with underlying thrombotic disorders such as polycythemia rubra vera, paroxysmal nocturnal hemoglobinuria and pregnancy. It may also occur secondary to a variety of tumours, chronic inflammatory diseases and infections. Imaging plays an important role both in establishing the diagnosis of Budd-Chiari syndrome as well as evaluating for underlying causes and complications such as portal hypertension. In this review article, we discuss the role of modern imaging in the evaluation of Budd-Chiari syndrome. (orig.)

We, herein, examined the role of the intraluminal contents and continuity of colonic intrinsic neurons in intracolonic capsaicin-induced enhancement of colonic motility and defecation. Five beagle dogs were equipped with three strain gauge force transducers throughout the colon. The colonic contractile activity in response to intracolonic capsaicin was studied in intact dogs, dogs after colonic cleansing and dogs with transection/re-anastomosis (T/R) between the proximal and middle colon. The effects of intravenous yohimbine, a α2 adrenergic antagonist, on the colonic motility and defecation were also studied in the same models. In intact dogs, capsaicin (10 mg) and yohimbine (2 mg/kg) immediately induced contractions throughout the colon, with defecation occurring in all experiments. In dogs after colonic cleansing and T/R, the capsaicin (10 mg)-induced enhancement of colonic motility was decreased in the middle and distal colon, and capsaicin-induced defecation was observed in 0-20 % of experiments (p continuity of the colonic intrinsic nerves as well as the intraluminal contents appear to play an important role in the colonic motor response to intracolonic capsaicin.

Severe obesity sometimes leads to a chronic alveolar hypoventilation: obesity hypoventilation syndrome (OHS), (Pao245mmHG and body mass index (BMI)>30Kg/m2). The association with an OSAS is frequent. To assess predicting factors that lead to hypoventilation in a population of obese patients with SAS and to deduct the type of association between OHS and SAS. We have study during 4 years, at pneumology service of Charles Nicolle hospital, 62 obese patients (BMI>30Kg /m2), 41men and 21 women and presenting an OSAS. We excluded those carriers of a bronchial obstruction (VEMS/CV 40) in 77.8% of patients of the G1 with significant difference with the G2 (P=0.004). We noted that there is a positive interrelationship between BMI and Paco2. We identified severe gazométrique perturbation in G1 (Pao2 medium = 61± 9 mmHg,Paco2 medium=50 ± 7 mmHg), in the G2 we noted a moderate hypoxemia. Patients of the group1 make of the minimal desaturation of 63 ± 17% and a Sao2 average of 81 ± 20% what is meaningfully more important than in the G2. The alveolar hypoventilation in SAS seems to be in correlation with the degree of obesity. The hypercapnie in the OHS is in relation neither with the SAOS nor with its severity. The OHSSAS association is usual but not synonym; the OHS is an autonomous disease.

Rashid, Aatif; Nanjappa, Sowmya; Greene, John N

2017-01-01

Right middle lobe (RML) syndrome is defined as recurrent or chronic obstruction or infection of the middle lobe of the right lung. Nonobstructive causes of middle lobe syndrome include inflammatory processes and defects in the bronchial anatomy and collateral ventilation. We report on 2 case patients with RML syndrome, one due to infection with Mycobacterium avium complex followed by M asiaticum infection and the other due to allergic bronchopulmonary aspergillosis. A history of atopy, asthma, or chronic obstructive pulmonary disease has been reported in up to one-half of those with RML. The diagnosis can be made by plain radiography, computed tomography, and bronchoscopy. Medical treatment consists of bronchodilators, mucolytics, and antimicrobials. Patients whose disease is unresponsive to treatment and those with obstructive RML syndrome can be offered surgical treatment.

Background: Patients with obstructive sleep apnea/hypopnea syndrome (OSAHS), even those generally compliant with CPAP therapy, often intermittently discontinue CPAP. Study Objective: Examine the impact of CPAP withdrawal on sleep, sleep disordered breathing (SDB), and daytime function in subjects with varying severity of OSAHS. Patients and Interventions: Forty-two subjects (26M/16 F) with OSAHS (AHI4% = 45.2 ± 35.5/h pretreatment) on CPAP for 4 months were evaluated on the second night of CPAP withdrawal. Sleep architecture, SDB indices, and subjective/objective daytime function were assessed pretreatment, on CPAP therapy, and after CPAP withdrawal. Comparisons were made between pretreatment and CPAP withdrawal for the entire group, and for subgroups of mild/moderate (AHI4% 30/h, n = 20) SDB. Results: Overall, and for mild/moderate subjects, SDB indices returned to pretreatment values on CPAP withdrawal but with fewer apneas and more hypopneas/RERAs. For severe SDB, the event frequency (AI, AHI4%, and RDI) was lower and O2 desaturation was improved on CPAP withdrawal. Across SDB severity, sleep architecture showed lower %REM (15.6% vs 12.9%, P = 0.009) on the CPAP withdrawal compared to pretreatment. Stanford Sleepiness Score, MSLT, and PVT measures were not significantly different between pretreatment and CPAP withdrawal. Conclusions: Over a wide range of SDB severity CPAP withdrawal results in recurrence of SDB, albeit with less severe O2 desaturation. Subjective/objective daytime function returned to pretreatment levels. Sleep architecture changes on CPAP withdrawal (acute SDB) may reflect reduced sleep pressure compared to pretreatment chronic SDB. Our data suggest detrimental effects of even brief withdrawal of CPAP in subjects with both mild and severe OSAHS. Citation: Young LR; Taxin ZH; Norman RG; Walsleben JA; Rapoport DM; Ayappa I.

Results. We have examined 80 children aged from 6 months to 3 years with acute obstructive bronchitis, and 40 age-matched children with acute nonobstructive bronchitis. The factors of high risk were determined and the mathematical model for predicting bronchial obstruction in acute bronchitis was created. Father’s age over 38 years, intrauterine growth restriction, maladjustment syndrome, early artificial feeding, genetic predisposition to atopy, passive smoking, fever in the postvaccination period, history of acute obstructive bronchitis and number of its episodes more than 2, paratrophia became prognostically significant. Fever up to 37.7 °C, mild intoxication syndrome up to 3 days, slow nasal breathing, IL-13 within 4.05–6.71 pg/ml and the relative number of lymphocytes expressing NF-kB less than 49.8 % were also associated with the development of bronchial obstruction in acute bronchitis.

The role of nasal CPAP in obstructive sleep apnoea syndrome due to mandibular hypoplasia.

Miller, Stanley D W

2012-02-01

Melnick Needles syndrome (MNS), Treacher Collins syndrome (TCS) and Pierre Robin syndrome (PRS) are congenital abnormalities with characteristic facial appearances that include micrognathia. A 20-year-old girl with MNS, a 16-year-old boy with TCS and a 12-year-old girl with PRS attended the sleep apnoea clinic at our institution at different times. Diagnostic sleep studies were initially performed on all three patients to confirm the diagnosis of obstructive sleep apnoea syndrome (OSAS). They subsequently commenced nasal CPAP (nCPAP) treatment and their progress was followed. A limited sleep study on the patient with MNS demonstrated moderate\\/severe OSAS with an AHI of 33 events\\/h. Commencement of nCPAP resulted in symptomatic improvement. Overnight oximetry in the patient with TCS showed repeated desaturation to SpO2<90%. Subsequent treatment by nCPAP almost completely abolished the desaturation events. Overnight polysomnography in the patient with PRS demonstrated severe OSAS with an AHI of 49 events\\/h. After 3 years of nCPAP therapy, this patient requested discontinuation of treatment. Subsequent polysomnography without nCPAP revealed an AHI of <5 events\\/h. The use of nCPAP in the patients with MNS and TCS resulted in effective control of their sleep abnormalities. Mandibular growth and enlargement of the posterior airway space led to resolution of OSAS in the patient with PRS. There is a definite role for nCPAP therapy in patients with congenital micrognathia and OSAS. The use of nCPAP may obviate the need for more invasive corrective surgery for OSAS and is not necessarily a life-long requirement.

Airflow obstruction: is it asthma or is it COPD?

Full Text Available Paola Rogliani, Josuel Ora, Ermanno Puxeddu, Mario Cazzola Department of Systems Medicine, Tor Vergata University of Rome, Rome, Italy Abstract: Despite the availability of guideline recommendations, diagnostic confusion between COPD and asthma appears common, and often it is very difficult to decide whether the obstruction is caused by asthma or COPD in a patient with airway obstruction. However, there are well-defined features that help in differentiating asthma from COPD in the presence of fixed airflow obstruction. Nonetheless, the presentations of asthma and COPD can converge and mimic each other, making it difficult to give these patients a diagnosis of either condition. The association of asthma and COPD in the same patient has been designated mixed asthma–COPD phenotype or overlap syndrome. However, since the absence of a clear definition and the inclusion of patients with different characteristics under this umbrella term, it may not facilitate treatment decisions, especially in the absence of clinical trials addressing this heterogeneous population. We are realizing that neither asthma nor COPD are single diseases, but rather syndromes consisting of several endotypes and phenotypes, consequently comprising a spectrum of diseases that must be recognized and adequately treated with targeted therapy. Therefore, we must treat patients by personalizing therapy on the basis of those treatable traits present in each subject.

Sinusoidal obstruction syndrome (SOS), a form of drug-induced liver injury related to oxaliplatin treatment, is associated with postoperative morbidity after hepatectomy. This study aimed to examine the impact of regorafenib, the first small-molecule kinase inhibitor to show efficacy against metastatic colorectal cancer, on a rat model of SOS. Rats with monocrotaline (MCT)-induced SOS were divided into two groups according to treatment with either regorafenib (6 mg/kg) or vehicle alone, which were administered at 12 and 36 h, respectively, before MCT administration. Histopathologic examination and serum biochemistry tests were performed 48 h after MCT administration. Sinusoidal endothelial cells were evaluated by immunohistochemistry and electron microscopy. To examine whether regorafenib preserved remnant liver function, a 30% hepatectomy was performed in each group. The rats in the vehicle group displayed typical SOS features, whereas these features were suppressed in the regorafenib group. The total SOS scores were significantly lower in the regorafenib group than in the vehicle group. Immunohistochemistry and electron microscopy showed that regorafenib had a protective effect on sinusoidal endothelial cells. The postoperative survival rate after 7 d was significantly better in the regorafenib group than that in the vehicle group (26.7% versus 6.7%, P Regorafenib reduced the phosphorylation of extracellular signal-regulated kinase, which induced matrix metalloproteinase-9 (MMP-9) activation and decreased the activity of MMP-9, one of the crucial mediators of SOS development. Regorafenib suppressed MCT-induced SOS, concomitant with attenuating extracellular signal-regulated kinase phosphorylation, and MMP-9 activation, suggesting that regorafenib may be a favorable agent for use in combination with oxaliplatin-based chemotherapy.

The obstructive sleep apnoea syndrome (OSAS) results from a combination of structural and neuromotor factors; however, the relative contributions of these factors have not been studied during the important developmental phase of adolescence. We hypothesised that adenotonsillar volume (ATV), nasopharyngeal airway volume (NPAV), upper airway critical closing pressure (Pcrit) in the hypotonic and activated neuromotor states, upper airway electromyographic response to subatmospheric pressure and the ventilatory response to CO 2 during sleep would be major predictors of OSAS risk. 42 obese adolescents with OSAS and 37 weight-matched controls underwent upper airway MRI, measurements of Pcrit, genioglossal electromyography and ventilatory response to CO 2 during wakefulness and sleep. ATV, NPAV, activated and hypotonic Pcrit, genioglossal electromyography and ventilatory response to CO 2 during sleep were all associated with OSAS risk. Multivariate models adjusted for age, gender, body mass index and race indicated that ATV, NPAV and activated Pcrit each independently affected apnoea risk in adolescents; genioglossal electromyography was independently associated in a reduced sample. There was significant interaction between NPAV and activated Pcrit (p=0.021), with activated Pcrit more strongly associated with OSAS in adolescents with larger NPAVs and NPAV more strongly associated with OSAS in adolescents with more negative activated closing pressure. OSAS in adolescents is mediated by a combination of anatomic (ATV, NPAV) and neuromotor factors (activated Pcrit). This may have important implications for the management of OSAS in adolescents.

Thin-section CT studies in six patients with bronchiolitis obliterans syndrome (age range, 2 months to 5 1/2 years) and in 15 control patients without obstructive airway disease (age range, 2 months to 7 years) who underwent bilateral lung transplantation were retrospectively reviewed. The thin-section CT scans were obtained during quiet sleep at a median of 24 months (range, 6-36 months) after transplantation. The CT studies were evaluated for mosaic perfusion, bronchial dilatation, bronchial wall thickening, and mucous plugging Final diagnoses in all patients were based pulmonary function test results. Thin-section CT findings in the six patients with clinically proved bronchiolitis obliterans syndrome were mosaic perfusion in five (83%) bronchial dilation in three (50%), and bronchial wall thickening in one (17%). Of the 15 control patients with normal pulmonary function test results, six (40%) had mosaic perfusion; none had bronchial dilatation or bronchial wall thickening. Mucous plugging was not seen in either group. Only the association of bronchial dilatation with bronchiolitis obliterans syndrome was significant (P = .02). Infants and young children with bronchiolitis obliterans syndrome after lung transplantation are more likely to have CT abnormalities than those with normal pulmonary function test results.

Débora Aparecida Oliveira Modena

Full Text Available Summary Introduction: The obstructive sleep apnea syndrome (OSAS is a respiratory illness, characterized by recurrent episodes of apnea and hypopnea, leading to reduction or cessation of the airflow. Obesity is one of the major risk factors for the development of OSAS. To help in the diagnosis of this disease, easily applicable and low-cost questionnaries were developed, such as the Berlin Questionnaire (BQ. Objective: To evaluate the efficacy of the BQ for the screening of OSAS among candidates to bariatric surgery in a multidisciplinary preoperative program. Method: This is an observational, descriptive and cross-sectional study which evaluated obese individuals that were being prepared for bariatric surgery by means of the BQ. Results: BQ was able to detect that minimal variations in the body mass index, neck circumference and hip-to-waist ratio lead to changes in the risk to develop OSAS; the higher the values of these variables, the higher the risk for OSAS development. Conclusion: BQ was an efficient and reliable tool to demonstrate the high risk for OSAS development in individual with obesity.

Paediatric Obstructive Sleep Apnoea-Hypopnoea Syndrome (OSAS) is a multisystemic condition affecting child's health status that may be investigated analyzing demand for healthcare. to quantify the frequency of medical consultations in children with OSAS over a 5-year period, compared to a healthy population. A longitudinal, case-control, ambispective study was conducted at a hospital pertaining to the national public health system. 69 consecutive children referred for OSAS were recruited with no diseases other than OSAS so that healthcare demand was purely attributed to this condition. Matched healthy control children were selected to compare these data. Data regarding frequency of the medical consultations were obtained over 5 years: the year of the treatment ("Year0"), 1 and 2 years before ("Year -1" and "Year -2" respectively), and 1 and 2 years after treatment ("Year+1" and "Year+2") RESULTS: Frequentation Index (FI), as ratio between the use of health services by OSAS children and healthy controls was 1.89 during Year-2, and 2.15 during Year-1 (Pde Otorrinolaringología y Cirugía de Cabeza y Cuello.

Structural abnormalities in the upper airway and surrounding soft tissues may contribute to the obstructive sleep apnea syndrome (OSAS). The authors have utilized MR imaging (3-mm contiguous T1-weighted sagittal images obtained with a local coil at 1.5 T) combined with a computer graphics-based analysis of three-dimensional geometry to study the upper airways of 10 awake, supine normal subjects (29--50 years-old), seven patients with OSAS (34--54 years old), and a nonapneic snorer (24 years old). Upper-airway anatomic segments were compared with regard to regional volumes, minimum cross-sectional areas, and pharyngeal wall thickness. Results to date show a smaller retropalatial airway volume in the patients with OSAS (1.8 cm 3 ± 0.8 [SEM]) and a smaller minimum cross-sectional retropalatal area in patients with OSAS (0.45 cm 2 ) than in the nonapneic snorer (0.9 cm 2 ) and the normal subjects (2.5 cm 2 ± 0.2)

A new type of defecation disorder due to insufficient fixation of the rectum to the sacrum is improved by rectopexy: A report of three cases

Full Text Available Chronic constipation is the most common clinical disorder in children. However, some cases of constipation do not meet the criteria defined by Rome III. We encountered such defecation disorders in three patients who presented with constipation as a chief complaint along with excessive strain and bleeding hemorrhoids during defecation despite normal stools. Contrast enema revealed that the rectum was separated from the sacrum in each patient, which may have been caused by insufficient fixation of the rectum. Conservative treatment with laxatives and suppositories failed to achieve improvement. Therefore, all underwent a laparoscopic rectopexy. After surgery, each patient was able to evacuate without strain and the hemorrhoids disappeared. Insufficient fixation of the rectum should be considered as a potential cause of defecation disorders. Rectopexy is effective for this type of defecation disorder.

1992-03-15

Chronic intestinal pseudoobstruction syndrome is a rare clinical condition in which impaired intestinal peristalsis causes recurrent symptoms of bowel obstruction in the absence of a mechanical occlusion. This syndrome may involve variable segments of small or large bowel, and may be associated with urinary bladder retention. This study included 6 children(3 boys and 3 girls) of chronic intestinal obstruction. Four were symptomatic at birth and two were of the ages of one month and one year. All had abdominal distension and deflection difficulty. Five had urinary bladder distension. Despite parenteral nutrition and surgical intervention(ileostomy or colostomy), bowel obstruction persisted and four patients expired from sepses within one year. All had gaseous distension of small and large bowel on abdominal films. In small bowel series, consistent findings were variable degree of dilatation, decreased peristalsis(prolonged transit time) and microcolon or microrectum. This disease entity must be differentiated from congenital megacolon, ileal atresia and megacystis syndrome.

Cardiovascular disease in obstructive sleep apnoea syndrome: the role of intermittent hypoxia and inflammation.

LENUS (Irish Health Repository)

Garvey, J F

2012-02-01

There is increasing evidence that intermittent hypoxia plays a role in the development of cardiovascular risk in obstructive sleep apnoea syndrome (OSAS) through the activation of inflammatory pathways. The development of translational models of intermittent hypoxia has allowed investigation of its role in the activation of inflammatory mechanisms and promotion of cardiovascular disease in OSAS. There are noticeable differences in the response to intermittent hypoxia between body tissues but the hypoxia-sensitive transcription factors hypoxia-inducible factor-1 and nuclear factor-kappaB appear to play a key role in mediating the inflammatory and cardiovascular consequences of OSAS. Expanding our understanding of these pathways, the cross-talk between them and the activation of inflammatory mechanisms by intermittent hypoxia in OSAS will provide new avenues of therapeutic opportunity for the disease.

Caenorhabditis elegans Male Copulation Circuitry Incorporates Sex-Shared Defecation Components To Promote Intromission and Sperm Transfer

Sexual dimorphism can be achieved using a variety of mechanisms, including sex-specific circuits and sex-specific function of shared circuits, though how these work together to produce sexually dimorphic behaviors requires further investigation. Here, we explore how components of the sex-shared defecation circuitry are incorporated into the sex-specific male mating circuitry in Caenorhabditis elegans to produce successful copulation. Using behavioral studies, calcium imaging, and genetic manipulation, we show that aspects of the defecation system are coopted by the male copulatory circuitry to facilitate intromission and ejaculation. Similar to hermaphrodites, male defecation is initiated by an intestinal calcium wave, but circuit activity is coordinated differently during mating. In hermaphrodites, the tail neuron DVB promotes expulsion of gut contents through the release of the neurotransmitter GABA onto the anal depressor muscle. However, in the male, both neuron and muscle take on modified functions to promote successful copulation. Males require calcium-dependent activator protein for secretion (CAPS)/unc-31, a dense core vesicle exocytosis activator protein, in the DVB to regulate copulatory spicule insertion, while the anal depressor is remodeled to promote release of sperm into the hermaphrodite. This work shows how sex-shared circuitry is modified in multiple ways to contribute to sex-specific mating. PMID:28031243

Constipation is a common health problem that adversely affects quality of life and the prognosis of hospitalized patients with acute coronary syndromes (ACS). The purpose of this study was to develop and test the sweet potato/footbath/acupressure massage (SFA) intervention as a safe treatment for prevention of constipation and to increase satisfaction with bowel emptying in hospitalized patients with ACS. The study was a prospective, randomized controlled trial with a sample of 93 patients (SFA group, n = 44; usual care group, n = 49). Patients in the SFA group received SFA intervention combined with usual care. The results showed that there were statistical differences between the two groups in terms of (1) the incidence of constipation; (2) the use of laxatives and enemas; (3) patients' subjective satisfaction with their bowel emptying during hospitalization; and (4) sensation of incomplete evacuation and anorectal obstruction/blockade. The SFA intervention was more effective, economical, and practical than usual care alone in managing constipation and satisfaction with defecation in patients hospitalized with ACS.

To establish the diagnostic test accuracy of both two-dimensional (2D) and four-dimensional (4D) transperineal ultrasound, to assess if 4D ultrasound imaging provides additional value in the diagnosis of posterior pelvic floor disorders in women with obstructed defaecation syndrome. In this prospective cohort study, 121 consecutive women with obstructed defaecation syndrome were recruited. Symptoms of obstructed defaecation and signs of pelvic organ prolapse were assessed using validated methods. All women underwent both 2D transperineal ultrasound (Pro-focus, 8802 transducer, BK-medical) and 4D transperineal ultrasound (Voluson i, RAB4-8-RS transducer, GE). Imaging analysis was performed by two blinded observers. Pelvic floor disorders were dichotomised into presence or absence according pre-defined cut-off values. In the absence of a reference standard a composite reference standard was created from a combination of results of evacuation proctogram, magnetic resonance imaging and endovaginal ultrasound. Primary outcome measures were diagnostic test characteristics of 2D and 4D transperineal ultrasound for diagnosis or rectocele, enterocele, intussusception and anismus. Secondary outcome measures were interobserver agreement, agreement between the two techniques and correlation of signs and symptoms to imaging findings. For diagnosis of all four posterior pelvic floor disorders there was no difference in sensitivity and specificity between 2D and 4D TPUS (p= 0.131 - 1.000). A good agreement between 2D and 4D TPUS was found for the diagnosis of rectocele (ĸ 0.675) and a moderate agreement for diagnosis of enterocele, intussusception and anismus (ĸ 0.465 - 0.545). There was no difference in rectocele depth measurements between both TPUS techniques (19.9 mm vs 19.0 mm, p=0.802). Inter-observer agreement was comparable for both techniques, however 2D TPUS had an excellent interobserver agreement for diagnosis of enterocele and rectocele depth measurements. Diagnosis

Pharmacological Management of Elderly Patients with Asthma-Chronic Obstructive Pulmonary Disease Overlap Syndrome: Room for Speculation?

Castiglia, Daniela; Battaglia, Salvatore; Benfante, Alida; Sorino, Claudio; Scichilone, Nicola

2016-06-01

Asthma and chronic obstructive pulmonary disease (COPD) are two distinct diseases that share a condition of chronic inflammation of the airways and bronchial obstruction. In clinical settings, it is not rare to come across patients who present with clinical and functional features of both diseases, posing a diagnostic dilemma. The overlap condition has been termed asthma-COPD overlap syndrome (ACOS), and mainly occurs in individuals with long-standing asthma, especially if they are also current or former smokers. Patients with ACOS have poorer health-related quality of life and a higher exacerbation rate than subjects with asthma or COPD alone. Whether ACOS is a distinct nosological entity with genetic variants or rather a condition of concomitant diseases that overlap is still a matter of debate. However, there is no doubt that extended life expectancy has increased the prevalence of asthma and COPD in older ages, and thus the probability that overlap conditions occur in clinical settings. In addition, age-associated changes of the lung create the basis for the two entities to converge on the same subject. ACOS patients may benefit from a stepwise treatment similar to that of asthma and COPD; however, the proposed therapeutic algorithms are only speculative and extrapolated from studies that are not representative of the ACOS population. Inhaled corticosteroids are the mainstay of therapy, and always in conjunction with long-acting bronchodilators. The potential heterogeneity of the overlap syndrome in terms of inflammatory features (T helper-1 vs. T helper-2 pathways) may be responsible for the different responses to treatments. The interaction between respiratory drugs and concomitant diseases should be carefully evaluated. Similarly, the effect of non-respiratory drugs, such as aspirin, statins, and β-blockers, on lung function needs to be properly assessed.

Sinusoidal Obstruction Syndrome (Hepatic Veno-Occlusive Disease)

Fan, Cathy Q.; Crawford, James M.

2014-01-01

Hepatic sinusoidal obstruction syndrome (SOS) is an obliterative venulitis of the terminal hepatic venules, which in its more severe forms imparts a high risk of mortality. SOS, also known as veno-occlusive disease (VOD), occurs as a result of cytoreductive therapy prior to hematopoietic stem cell transplantation (HSCT), following oxaliplatin-containing adjuvant or neoadjuvant chemotherapy for colorectal carcinoma metastatic to the liver and treated by partial hepatectomy, in patients taking pyrrolizidine alkaloid-containing herbal remedies, and in other particular settings such as the autosomal recessive condition of veno-occlusive disease with immunodeficiency (VODI). A central pathogenic event is toxic destruction of hepatic sinusoidal endothelial cells (SEC), with sloughing and downstream occlusion of terminal hepatic venules. Contributing factors are SEC glutathione depletion, nitric oxide depletion, increased intrahepatic expression of matrix metalloproteinases and vascular endothelial growth factor (VEGF), and activation of clotting factors. The clinical presentation of SOS includes jaundice, development of right upper-quadrant pain and tender hepatomegaly, ascites, and unexplained weight gain. Owing to the potentially critical condition of these patients, transjugular biopsy may be the preferred route for liver biopsy to exclude other potential causes of liver dysfunction and to establish a diagnosis of SOS. Treatment includes rigorous fluid management so as to avoid excessive fluid overload while avoiding too rapid diuresis or pericentesis, potential use of pharmaceutics such as defibrotide, coagulolytic agents, or methylprednisolone, and liver transplantation. Proposed strategies for prevention and prophylaxis include reduced-intensity conditioning radiation for HSCT, treatment with ursodeoxycholic acid, and inclusion of bevacizumab with oxaliplatin-based chemotherapeutic regimes. While significant progress has been made in understanding the pathogenesis

Results: There were 145, 56, and 34 patients in the mild, moderate, and severe COPD groups, respectively. The mean age increased gradually (52.4, 56.4, and 60.0 years) from the mild towards the severe COPD groups, respectively (p<0.05 nearly in all steps). Similarly, the mean direction (p<0.05 nearly in all steps). Parallel to them, the mean body mass index increased Conclusion: The metabolic syndrome includes some reversible indicators such as overweight, hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, impaired fasting glucose, impaired glucose tolerance, and white coat hypertension for the development of terminal diseases including obesity, hypertension, diabetes mellitus, peripheral artery disease, coronary heart disease, and stroke. In our opinion, COPD may be one of the terminal end points of the syndrome. (author)

To define the MRI findings of congenital high airway obstruction sequence (CHAOS) in a series of fetuses. Prenatal fetal MR images were reviewed in seven fetuses with CHAOS at 21 to 27 weeks of gestation. The MRI findings were reviewed. The MRI parameters evaluated included the appearance of the lungs and diaphragm, presence or absence of hydrops, amount of amniotic fluid, airway appearance, predicted level of airway obstruction, and any additional findings or suspected genetic syndromes. All the fetuses viewed (7 of 7) demonstrated the following MRI findings: dilated airway below the level of obstruction, increased lung signal, markedly increased lung volumes with flattened or inverted hemidiaphragms, massive ascites, centrally positioned and compressed heart, as well as placentomegaly. Other frequent findings were anasarca (6 of 7) and polyhydramnios (3 of 7). MRI identified the level of obstruction as laryngeal in five cases and tracheal in two cases. In four of the patients, surgery or autopsy confirmed the MRI predicted level of obstruction. Associated abnormalities were found in 4 of 7 (genetic syndromes in 2). Postnatal radiography (n = 3) showed markedly hyperinflated lungs with inverted or flattened hemidiaphragms, strandy perihilar opacities, pneumothoraces and tracheotomy. Two fetuses were terminated and one fetus demised in utero. Four fetuses were delivered via ex utero intrapartum treatment procedure. MRI shows a consistent pattern of abnormalities in fetuses with CHAOS, accurately identifies the level of airway obstruction, and helps differentiate from other lung abnormalities such as bilateral congenital pulmonary airway malformation by demonstrating an abnormally dilated airway distal to the obstruction.

Full text: Introduction: Obstructive sleep apnoea syndrome (OSAS) is associated with a large number of predisposing factors (obesity, nasal obstruction, adenoid hypertrophy, macroglossia etc.). In addition to these factors goiter and hypothyroidism have been reported to be associated with OSAS. Objectives and tasks: In our case with retrosternal goiter, values of OSAS before and after thyroidectomy were shown. Materials and methods: Seventy-two years old, BMI: 26,8 kg/m 2 , female patient was admitted our hospital because of complaints to stop breathing during sleep, snoring, morning headache and daytime drowsiness. Results: Thorax CT and ultrasonography of thyroid shown retrosternal goiter and left tracheal deviation. Severe OSAS was diagnosed by polysomnography (PSG). Thyroid function tests were normal. Apneahypopnea index (AHI) was 63,1/h. Patients was performed 7 cm H 2 O nasal continuous positive airway pressure (gvrnCPAP). AHI was 11,4/h under nCPAP. One month after OSAS diagnosis the patient underwent thyroidectomy operation. Pathological examination was reported as multinodular GOITER. In postoperative period CPAP treatment couldn't continue, because patient was not compliant. In postoperative 8-th weeks, PSG was performed; AHI was 34,8/h. The patient's weight and BMI didn't change. Conclusion: In our case, despite absence of continued CPAP treatment after thyroidectomy, symptoms and PSG values improved partially. As a result of these findings, especially, compression of upper airway and deterioration of venous circulation of patients with large goiter may lead to an increase in OSAS symptoms. During patients with OSAS are treated with CPAP, goiter needs to be investigated

Sleep-related disorders in chronic obstructive pulmonary disease.

LENUS (Irish Health Repository)

Crinion, Sophie J

2014-02-01

Sleep may have several negative consequences in patients with chronic obstructive pulmonary disease (COPD). Sleep is typically fragmented with diminished slow wave and rapid-eye-movement sleep, which likely represents an important contributing factor to daytime symptoms such as fatigue and lethargy. Furthermore, normal physiological adaptations during sleep, which result in mild hypoventilation in normal subjects, are more pronounced in COPD, which can result in clinically important nocturnal oxygen desaturation. The co-existence of obstructive sleep apnea and COPD is also common, principally because of the high prevalence of each disorder, and there is little convincing evidence that one disorder predisposes to the other. Nonetheless, this co-existence, termed the overlap syndrome, typically results in more pronounced nocturnal oxygen desaturation and there is a high prevalence of pulmonary hypertension in such patients. Management of sleep disorders in patients with COPD should address both sleep quality and disordered gas exchange. Non-invasive pressure support is beneficial in selected cases, particularly during acute exacerbations associated with respiratory failure, and is particularly helpful in patients with the overlap syndrome. There is limited evidence of benefit from pressure support in the chronic setting in COPD patients without obstructive sleep apnea.

Dyssynergic defecation may play an important role in postoperative Hirschsprung's disease patients with severe persistent constipation: analysis of a case series.

After surgery for Hirschsprung's disease (HD) the majority of patients have satisfactory clinical outcomes. Nevertheless, a substantial number of patients remain who suffer from severe persistent constipation. Current consensus attributes these complaints to the hallmarks of HD. In non-HD patients a cause for severe constipation is dyssynergic defecation. Retrospectively, we reviewed the medical records of ten postoperative HD patients with severe persistent constipation who had undergone extensive anorectal function tests to diagnose the reason for the constipation. We analyzed the results of these tests. During the last three years, ten postoperative HD patients with severe persistent constipation were given extensive anorectal function tests. All ten patients were diagnosed with dyssynergic defecation. The ages at the time of diagnosis ranged from 7 to 19years with a median age of 12years. Signs of an enlarged rectum were seen in all ten patients, with a maximum measured value of 845mL. Patients with HD may also suffer from dyssynergic defecation. It is important to consider this possibility when dealing with severe persistent constipation in postoperative HD patients. Viable options for treating dyssynergic defecation are available that could prevent irreversible long-term complications. Copyright © 2014 Elsevier Inc. All rights reserved.

Chagas disease is caused by the protozoan Trypanosoma cruzi Panstrongylus chinai (Del Ponte) is highly domiciliated in the Peruvian and Ecuadorian Andes and has been found naturally infected with T. cruzi The objective of this study was to describe the life cycle, feeding, and defecation patterns of P. chinai in the Loja province within southern Ecuador. To characterize its life cycle, a cohort of 70 individuals was followed from egg to adult. At each stage of development, prefeeding time, feeding time, weight of ingested meal, proportional weight increase, and the time to the first defecation were recorded. Panstrongylus chinai completed its development in 371.4 ± 22.3 d, (95% CI 355.4-387.4), which means that it is likely a univoltine species. Prefeeding time, feeding time, and weight of ingested meal increased as individuals developed through nymphal stages. Moreover, time to first defecation was shortest in the early nymphal stages, suggesting higher vector potential in the early developmental stages. Data obtained in this study represent an important advance in our knowledge of the biology of P. chinai, which should be considered as a secondary Chagas disease vector species in the Andean valleys of Loja (Ecuador) and in the north of Peru, and included in entomological surveillance programs. © The Authors 2016.

2008-01-01

Budd-Chiari syndrome is an uncommon but often fatal disorder resulting from obstruction of hepatic venous outflow tract at the level of the hepatic veins, the inferior vena cava. The CT and MRI characteristics of Budd-Chiari syndrome are reviewed in this article especially for displaying the exact site and extent of the obstruction. In addition to this direct sign, the indirect findings of venous obstruction such as the presence of intra-and extrahepatic collateral veins, caudate lobe enlargement, inhomogeneous liver enhancement, and regenerative nodules can also be demonstrated. Awareness of these findings is important for early diagnosis and appropriate treatment. (authors)

Full Text Available Overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (COPD and obstructive sleep apnea (OSA, was first defined by Flenley. Although it can refer to concomitant occurrence of any of the pulmonary diseases and OSA, overlap syndrome is commonly considered as the coexistence of OSA and COPD. This disease has unique adverse health consequences distinct from either condition alone. Given the high prevalence of each solitary disease, overlap syndrome is also likely to be common and clinically relevant. Despite the fact that overlap syndrome has been described in the literature for nearly 30 years, paucity of evaluations and studies limited the discussion on diagnosis, prevalence, pathophysiology, treatment, and outcomes of this disease. This review article addresses these issues by reviewing several recent studies conducted in Iran or other countries. This review suggests that overlap syndrome has worse outcomes than either disease alone. Our findings accentuated the urgent need for further studies on overlap syndrome and all overlaps between OSA and chronic pulmonary disease to provide a deeper insight into diagnosis and non-invasive treatments of this disease.

Multi-feature snore sound analysis in obstructive sleep apnea–hypopnea syndrome

2011-01-01

Snoring is the most common symptom of obstructive sleep apnea hypopnea syndrome (OSAHS), which is a serious disease with high community prevalence. The standard method of OSAHS diagnosis, known as polysomnography (PSG), is expensive and time consuming. There is evidence suggesting that snore-related sounds (SRS) carry sufficient information to diagnose OSAHS. In this paper we present a technique for diagnosing OSAHS based solely on snore sound analysis. The method comprises a logistic regression model fed with snore parameters derived from its features such as the pitch and total airway response (TAR) estimated using a higher order statistics (HOS)-based algorithm. Pitch represents a time domain characteristic of the airway vibrations and the TAR represents the acoustical changes brought about by the collapsing upper airways. The performance of the proposed method was evaluated using the technique of K-fold cross validation, on a clinical database consisting of overnight snoring sounds of 41 subjects. The method achieved 89.3% sensitivity with 92.3% specificity (the area under the ROC curve was 0.96). These results establish the feasibility of developing a snore-based OSAHS community-screening device, which does not require any contact measurements

Obstructive sleep apnea syndrome and hypothyroidism - merely concurrence or causal association?

2016-01-01

The prevalence of obstructive sleep apnea-hypopnea syndrome (OSAHS) ranges from 4 to 7% in men and from 2 to 5% in women. Its deleterious consequences such as traffic accidents, cardiovascular complications increasing morbidity and mortality, make it a major health problem. Apart from obesity (a major risk factor for OSAHS), hypothyroid patients are prone to reveal this phenotype. Although hypothyroidism seems an acknowledged risk factor for OSAHS, some authors report the lack of clinically relevant association. The argument partly depends on the increased prevalence of hypothyroidism in OSAHS patients, but the epidemiological data is limited and somehow inconsistent; even less is known about sub-clinical hypothyroidism in OSAHS patients. Even if frequency of overt and sub-clinical hypothyroidism in OSAHS patients is comparable to the general population, screening for it seems beneficial, as hormone replacement therapy may improve sleep disordered breathing. Unfortunately, this favorable outcome was found only in a few studies with limited number of patients with hypothyroidism. Yet, despite the lack of international guidelines and no large multicentre studies on the topic available, we think that TSH screening might prove beneficial in vast majority of OSAHS patients.

The wood cockroach Cryptocercus punctulatus nests as family units inside decayed wood, a substrate known for its high microbial load. We tested the hypothesis that defecation within their nests, a common occurrence in this species, reduces the probability of fungal development. Conidia of the entomopathogenic fungus, Metarhizium anisopliae, were incubated with crushed feces and subsequently plated on potato dextrose agar. Relative to controls, the viability of fungal conidia was significantly reduced following incubation with feces and was negatively correlated with incubation time. Although the cockroach's hindgut contained abundant β-1,3-glucanase activity, its feces had no detectable enzymatic function. Hence, these enzymes are unlikely the source of the fungistasis. Instead, the antifungal compound(s) of the feces involved heat-sensitive factor(s) of potential microbial origin. When feces were boiled or when they were subjected to ultraviolet radiation and subsequently incubated with conidia, viability was "rescued" and germination rates were similar to those of controls. Filtration experiments indicate that the fungistatic activity of feces results from chemical interference. Because Cryptocercidae cockroaches have been considered appropriate models to make inferences about the factors fostering the evolution of termite sociality, we suggest that nesting in microbe-rich environments likely selected for the coupling of intranest defecation and feces fungistasis in the common ancestor of wood cockroaches and termites. This might in turn have served as a preadaptation that prevented mycosis as these phylogenetically related taxa diverged and evolved respectively into subsocial and eusocial organizations.

The authors describe the surgical approach, findings, and 8-year follow-up in a 29-year-old woman, with severe Freeman-Sheldon syndrome, presenting with congenital blepharophimosis of both upper eyelids resulting in near-complete functional visual obstruction. To avoid possible Freeman-Sheldon syndrome-associated complications of malignant hyperthermia, difficult vascular access, and challenging endotracheal intubation, the surgery was completed under local anesthesia without sedation, and anatomical and functional correction was immediate and remained stable at 8-year follow-up. Unlike many congenital craniofacial syndromes, which frequently involve life-long impairments, important implications exist for plastic surgeons to facilitate opportunities for patients to overcome functional limitations.

A 36-year-old female with symptoms of orthostatic intolerance and syncope was diagnosed with vasovagal syncope on a tilt table test and with postural tachycardia syndrome (POTS) after a repeat tilt table test. However, an echocardiogram at our institution revealed obstructive cardiomyopathy without severe septal hypertrophy, with a striking increase in left ventricular outflow tract gradient from 7 mmHg at rest to 75 mmHg during Valsalva, with a septal thickness of only 1.3 cm. Cardiac MRI showed an apically displaced multiheaded posteromedial papillary muscle with suggestion of aberrant chordal attachments to the anterior mitral leaflet contributing to systolic anterior motion of the mitral valve. She underwent surgery with reorientation of the posterior medial papillary muscle head, resection of the tethering secondary chordae to the A1 segment of the mitral valve, chordal shortening and tacking of the chordae to the A1 and A2 segments of the mitral valve, and gentle septal myectomy. After surgery, she had significant improvement in her prior symptoms. To our knowledge, this is the first reported case of obstructive cardiomyopathy without severe septal hypertrophy with abnormalities in papillary muscle and chordal attachment, in a patient diagnosed with vasovagal syncope and POTS.

Nucleosomes and cell-free double-stranded DNA (dsDNA) have been suggested as promising biomarkers in cell death-related diseases, such as acute coronary syndrome (ACS). Currently, the impact of obstructive sleep apnea (OSA) in patients with ACS is unclear. Our aim was to evaluate the relationship between OSA, dsDNA, and nucleosomes and to assess their potential implication in the development of ACS. Up to 549 patients were included in the study and divided into four groups (145 ACS; 290 ACS + OSA; 62 OSA; 52 controls). All patients underwent a sleep study, and serum concentrations of dsDNA and nucleosomes were measured. Nucleosome and dsDNA levels were higher in patients with OSA than in controls (nucleosomes: 1.47 ± 0.88 arbitary units [AU] vs. 1.00 ± 0.33 AU; p Sleep Research Society 2017.

Raggi, Alberto; Ferri, Raffaele

2012-02-28

Cognitive functions may be altered in patients with obstructive sleep apnea syndrome (OSAS) and it has been proposed that vigilance and attention changes play a fundamental role in all aspects of cognitive deficits noted in this disease. The use of event-related potentials (ERPs) is a high-time resolution technique that can be used to explore the presence of cognitive dysfunction. We review 23 empirical articles on ERPs in OSAS in order to contribute to the clarification of the pattern of cognitive deficits that are specific to this disease and to see whether there might be an improvement of abnormal psychophysiological findings with continuous positive airway pressure (CPAP) treatment. We conclude that ERP studies have contributed to demonstrating changes in cognitive attentive processing in OSAS, mainly in association with altered functioning of the prefrontal cortex, and that CPAP treatment may improve vigilance and attention and generally improve cerebral information processing in these patients. The remaining deficits during sufficient CPAP therapy may, however, reflect irreversible hypoxic cerebral damage.

Sinusoidal obstruction syndrome (SOS) is one of the life-threatening complications caused by endothelial damage to the hepatic sinusoids after hematopoietic stem cell transplantation. However, a satisfactory treatment for SOS has not yet been established. Defibrotide has anti-thrombotic, anti-ischemic, anti-inflammatory, and thrombolytic properties without systemic anticoagulant effects. We treated eight post-transplant SOS patients with defibrotide. Three patients responded to the therapy and the initial response was observed within a week. In addition to the improvement of liver function, rapid recovery of response to diuretic drugs followed by the improvement of renal function was observed. All of the five patients with respiratory dysfunction died despite administration of defibrotide, suggesting that early treatment might lead to better outcomes. There were no severe adverse effects directly due to defibrotide administration. Defibrotide seems to be a promising treatment for SOS, and the initiation of a clinical study in Japan would be important.

Antenatal Bartter syndrome is a rare condition that can present with different clinical features. These features include early onset maternal polyhydramnios, failure to thrive, prematurity and nephrocalcinosis.We are presenting this 20-day-old girl who had an antenatal history of polyhydramnios. She developed persistent non-bilious vomiting that was associated with constipation soon after birth. She presented with failure to thrive and features suggestive of intestinal obstruction. On the initial evaluation, she was noted to have hypokalaemic, hyponatraemic metabolic alkalosis. The initial work-up was done to exclude surgical and renal causes of her presentation, and the diagnosis was confirmed by gene analysis to be type III-classic Bartter syndrome. She was closely monitored for her growth and development with the appropriate salt replacement therapy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

This paper presents a radiologic evaluation of defecation disorders. Twenty-five patients with symptoms of defecation disorders who presented clinically the findings of dysplasia of the external anal sphincter were examined with endorectal US, defecography, and CT. The findings were compared with those of 15 patients who were given a radiologic examination of the pelvis for other reasons. All patients of the first group underwent surgery. The radiological findings are as follows: defecography: a short anal canal (below 1 cm) and a dorsal anocele; CT: a failure of attachment of the external and sphincter to the coccyx; Endorectal US and CT: absence of posterior parts of the external anal sphincter. None of these findings were demonstrated in the comparison group. All patients of the first group underwent surgery and were proved intraoperatively to have dysplasia of the external anal sphincter, which was corrected subsequently. The authors' results show that at least two kinds of external and anal sphincter dysplasia exist. The results of the radiologic examinations correspond with the intraoperative findings. The authors believe that in chronic constipation in children or adults the radiologic examinations mentioned above should be done because surgical correction of anal sphincter dysplasia leads to an immediate improvement of defecation disorders

Obstructive sleep apnea syndrome (OSAS) has received much attention in recent years due to its significant harm to human health and high morbidity rate. A respiration monitoring system is needed to detect OSAS, so that the patient can receive treatment in a timely manner. Wired and wireless OSAS monitoring systems have been developed, but they require a wire connection and batteries to operate, and they are bulky, heavy and not user-friendly. In this paper, we propose the use of a flexible surface acoustic wave (SAW) microsensor to detect and monitor OSAS by measuring the humidity change associated with the respiration of a person. SAW sensors on rigid 128° YX LiNbO3 substrate are also characterized for this application. Results show both types of SAW sensors are suitable for OSAS monitoring with good sensitivity, repeatability and reliability, and the response time and recovery time for the flexible SAW sensors are 1.125 and 0.75 s, respectively. Our work demonstrates the potential for an innovative flexible microsensor for the detection and monitoring of OSAS.

Soluble (Prorenin Receptor and Obstructive Sleep Apnea Syndrome: Oxidative Stress in Brain?

Directory of Open Access Journals (Sweden)

Kazuhiro Takahashi

2017-06-01

Full Text Available (Prorenin receptor ((PRR is a multi-functional molecule that is related to both the renin-angiotensin system (RAS and vacuolar H+-ATPase (v-ATPase, an ATP-dependent multi-subunit proton pump. Soluble (PRR (s(PRR, which consists of the extracellular domain of (PRR, is present in blood and urine. Elevated plasma s(PRR concentrations are reported in patients with chronic kidney disease and pregnant women with hypertension or diabetes mellitus. In addition, we have shown that plasma s(PRR concentrations are elevated in patients with obstructive sleep apnea syndrome (OSAS. Interestingly, the levels are elevated in parallel with the severity of OSAS, but are not related to the presence of hypertension or the status of the circulating RAS in OSAS. It is known that v-ATPase activity protects cells from endogenous oxidative stress, and loss of v-ATPase activity results in chronic oxidative stress. We hypothesize that hypoxia and subsequent oxidative stress, perhaps in the brain, may be one of the factors that elevate plasma s(PRR levels in OSAS.

The relationship between obstructive sleep apnea syndrome (OSAS) and bronchial hyperresponsiveness (BHR) is not well known. In this study, we investigated the association between BHR and disease severity in patients with OSAS. Fourty seven (37 male/10 female) OSAS patients admitted with polysomnography enrolled to the study. Histamine bronchial challenge test was performed and body mass index (BMI, kg/m2) was calculated. Presence of BHR was diagnosed as positivity of bronchial provocative test (BPT) (PD values ≤ 16 mg/mL). Patients were questioned with Epworth sleepiness scale (ESS). Histamine bronchial challenge test was positive in 21 of 47 patients. There were significant negative correlations between PD 20 value and AHI (r= -0.47, p= 0.03), BMI (r= -0.45, p= 0.03), and ESS score (r= -0.45, p= 0.03) in the patients with BHR. In addition, AHI (p= 0.03), BMI (p= 0.02), ESS scores (p= 0.03) were higher in patients with BHR (21 patients) than in patients not having BHR (26 patients). Significant negative relation was found between PD 20 value and AHI (b=-0.45, p= 0.03) and significant positive relation was found between presence of BHR and AHI (p= 0.04), BMI (p= 0.03) independently of age and sex in multiple regression analysis. BHR is common in patients with OSAS. As severity of OSAS increased, severity of BHR increased. In addition, obesity may trigger presence of BHR in patients with OSAS.

The Rapunzel syndrome describes a disorder in which a significant amount of hair is swallowed, forming a trichobezoar that extends past the stomach into the small intestines. Given the indigestible nature of hair, it subsequently leads to obstruction within the gastrointestinal system. Clinically, patients may present with symptoms of gastrointestinal obstruction, including abdominal complaints such as pain, nausea, vomiting, and diarrhea. However, due to its broad and nonspecific presenting symptoms, the diagnosis of Rapunzel syndrome warrants consideration once other common etiologies have been excluded. Surgical intervention is often required to remove the abdominal mass. This unusual syndrome is often associated with psychiatric disorders, affecting young women most commonly. In this report, we will discuss a unique case of Rapunzel syndrome in a one-month postpartum woman.

Full Text Available The urofacial syndrome is characterized by functional obstructive uropathy asso-ciated with an inverted smile. The importance of the subject is that it sheds light, not only on the muscles of facial expression, but also on the inheritance of voiding disorders and lower urinary tract malformations. We report a 10-year-old-male patient who had the urofacial syndrome. Early diagnosis of the urofacial syndrome is important to avoid upper urinary tract damage and renal failure.

Congenital high airway obstruction syndrome (CHAOS) caused by laryngeal atresia was diagnosed by prenatal ultrasound in a male fetus at 26 weeks of gestation. Findings included massive ascites, subcutaneous edema, enlarged hyperechogenic lungs with diaphragmatic inversion, dilated trachea, polyhydramnios, and breech presentation. Those findings of CHAOS spontaneously returned to normal by 33 weeks of gestation. However, the placenta was localized to the anterior uterine wall. In addition, the fetal position had been breech until delivery. At 36 weeks of gestation, a planned ex utero intrapartum treatment (EXIT) procedure was performed following intraoperative external cephalic version (ECV) in which the fetus was approached from the posterior wall of the uterus. Laryngoscopy revealed the predicted laryngeal obstruction, and tracheostomy was placed. Intraoperative ECV may be a useful technique in breech presentation before EXIT procedure. © 2012 The Authors.

Uterine didelphys with obstructed hemivagina and ipsilateral renal anomalies is a rare congenital malformation of the female urogenital tract. While the urinary anomalies almost always involve renal agenesis, we report a rare case of a 17-year-old girl with the malformation associated with ectopic ureteral insertion into the obstructed hemivagina, which was diagnosed preoperatively by MR imaging. To the best of our knowledge, preoperative MR imaging diagnosis of the ectopic ureter associated with this syndrome has not been previously reported. Accurate preoperative diagnosis of ectopic ureteral insertion associated with this syndrome is important for surgical planning. (orig.)

Full Text Available ABSTRACT INTRODUCTION: Obstructive sleep apnea syndrome (OSAS is a common disorder that can lead to cardiovascular morbidity and mortality, as well as to metabolic, neurological, and behavioral consequences. It is currently believed that nasal obstruction compromises the quality of sleep when it results in breathing disorders and fragmentation of sleep. However, recent studies have failed to objectively associate sleep quality and nasal obstruction. OBJECTIVE: The aim of this systematic review is to evaluate the influence of nasal obstruction on OSAS and polysomnographic indices associated with respiratory events. METHODS: Eleven original articles published from 2003 to 2013 were selected, which addressed surgical and non-surgical treatment for nasal obstruction, performing polysomnography type 1 before and after the intervention. RESULTS/CONCLUSIONS: In most trials, nasal obstruction was not related to the apnea-hypopnea index (AHI, indicating no improvement in OSAS with reduction in nasal resistance. However, few researchers evaluated other polysomnography indices, such as the arousal index and rapid eye movement (REM sleep percentage. These could change with nasal obstruction, since it is possible that the nasal obstruction does not completely block the upper airways, but can increase negative intrathoracic pressure, leading to sleep fragmentation.

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a multisystemic disorder in which impaired intestinal motor activity causes recurrent symptoms of intestinal obstruction in the absence of mechanical occlusion, associated with bladder distention without distal obstruction of the urinary tract. MMIHS and prune belly syndrome may overlap in most of the clinical features and discrimination of these two entities is important because the prognosis, management and consulting with parents are completely different. MMIHS outcome is very poor and in this article we present two neonates with MMIHS that both died in a few days. PMID:23729700

Full Text Available Abstract Background Brachycephalic dogs have unique upper respiratory anatomy with abnormal breathing patterns similar to those in humans with obstructive sleep apnea syndrome (OSAS. The objective of this study was to evaluate the correlation between anatomical components, clinical signs and several biomarkers, used to determine systemic inflammation and myocardial damage (C-reactive protein, CRP; Haptoglobin, Hp; cardiac troponin I, cTnI, in dogs with brachycephalic upper airway obstructive syndrome (BAOS. Results Fifty brachycephalic dogs were included in the study and the following information was studied: signalment, clinical signs, thoracic radiographs, blood work, ECG, components of BAOS, and CRP, Hp and cTnI levels. A high proportion of dogs with BAOS (88% had gastrointestinal signs. The prevalence of anatomic components of BAOS was: elongated soft palate (100%, stenotic nares (96%, everted laryngeal saccules (32% and tracheal hypoplasia (29.1%. Increased serum levels of biomarkers were found in a variable proportion of dogs: 14% (7/50 had values of CRP > 20 mg/L, 22.9% (11/48 had values of Hp > 3 g/L and 47.8% (22/46 had levels of cTnI > 0.05 ng/dl. Dogs with everted laryngeal saccules had more severe respiratory signs (p Conclusions According to the low percentage of patients with elevated levels of CRP and Hp, BAOS does not seem to cause an evident systemic inflammatory status. Some degree of myocardial damage may occur in dogs with BAOS that can be detected by cTnI concentration.

Community Approaches to Total Sanitation (CATS) programmes, like the Sanitasi Total Berbasis Masyarakat (STBM) programme of the Government of Indonesia, have played a significant role in reducing open defecation though still little is known about the sustainability of the outcomes. We assessed the sustainability of verified Open Defecation Free (ODF) villages and explored the association between slippage occurrence and the strength of social norms through a government conducted cross-sectional data collection in rural Indonesia. The study surveyed 587 households and held focus group discussions (FGDs) in six ODF villages two years after the government's ODF verification. Overall, the slippage rate (i.e., a combination of sub-optimal use of a latrine and open defecation at respondent level) was estimated to be 14.5% (95% CI 11.6-17.3). Results of multivariate logistic regression analyses indicated that (1) weaker social norms, as measured by respondents' perceptions around latrine ownership coverage in their community, (2) a lack of all-year round water access, and (3) wealth levels (i.e., not being in the richest quintile), were found to be significantly associated with slippage occurrence. These findings, together with qualitative analysis, concluded that CATS programmes, including a combination of demand creation, removal of perceived constraints through community support mechanisms, and continued encouragement to pursue higher levels of services with post-ODF follow-up, could stabilize social norms and help to sustain longer-term latrine usage in study communities. Further investigation and at a larger scale, would be important to strengthen these findings.

The Rome II and III diagnostic criteria for dyssynergic defecation recommended the exclusion of irritable bowel syndrome (IBS). This study determined the effect of biofeedback therapy on dyssynergic constipation in patients with or without IBS. This study was a nonrandomized, single blinded, semi experimental study. Dyssynergic defecation patients with and without IBS were asked to undergo biofeedback therapy 8 sessions. The defecation dynamics and balloon expulsion time were evaluated before, at the end and 1 month after the biofeedback therapy. IBS symptoms were graded using a 4-point Likert scale. Mann-Whitney U-test, Wilcoxon test and Friedman test were applied to analyze data using SPSS software package (SPSS Inc., Chicago, IL, USA). After the biofeedback therapy, the IBS symptoms have been decreased significantly (the median of 2 before and 1 after therapy, P anismus index in IBS group by the mean of 0.75 ± 0.31, 0.28 ± 0.07 and 0.28 ± 0.06 in three phases, respectively. Similar results were found in non-IBS patients (the mean of 0.74 ± 0.32, 0.28 ± 0.08, 0.27 ± 0.08 in three phases, respectively). The symptoms of constipation (sensation of incomplete evacuation, difficult and painful defecation), defecation facilitative manual maneuver frequency, pelvic floor muscles resting amplitude and strain amplitude decreased and squeezing amplitude improved significantly after biofeedback therapy in both groups with and without IBS (P 0.05) with respect to outcome. No complication was observed in treatment groups. Dyssynergic constipation patients with and without IBS will likely benefit from biofeedback therapy.

Subjects and methods: The study was a cross-sectional prospective controlled clinical study. Heart rate variability indices of 24 COPD (n = 12 and COPD+OSAS (n = 12 patients were evaluated and compared by electrocardiographic recordings acquired during rest, active postural maneuver (APM, respiratory sinus arrhythmia maneuver (RSA-m, and the 6-minute walk test (6MWT. Results: The COPD group presented higher parasympathetic modulation during APM when compared to the COPD+OSAS group (P = 0.02. The COPD+OSAS group presented higher sympathetic modulation during RSA-m when compared to the COPD group (P = 0.00. The performance during 6MWT was similarly impaired in both groups, despite the greater severity of the COPD group. Conclusion: Subjects with COPD+OSAS present marked sympathetic modulation, and the presence of OSAS in COPD subjects has a negative impact on functional capacity regardless of the severity of lung disease.

To compare the results of computed tomography venography (CTV) with a fixed and a flexible delayed scan time for Budd-Chiari syndrome (BCS) with inferior vena cava (IVC) obstruction. A total of 209 consecutive BCS patients with IVC obstruction underwent either a CTV with a fixed delayed scan time of 180s (n=87) or a flexible delayed scan time for good image quality according to IVC blood flow in color Doppler ultrasonography (n=122). The IVC blood flow velocity was measured using a color Doppler ultrasound prior to CT scan. Image quality was classified as either good, moderate, or poor. Image quality, surrounding structures and the morphology of the IVC obstruction were compared between the two groups using a χ 2 -test or paired or unpaired t-tests as appropriate. Inter-observer agreement was assessed using Kappa statistics. There was no significant difference in IVC blood flow velocity between the two groups. Overall image quality, surrounding structures and IVC obstruction morphology delineation on the flexible delayed scan time of CTV images were rated better relative to those obtained by fixed delayed scan time of CTV images (ptime of CTV. There were no significant differences in Kappa statistics between Group A and Group B. The flexible delayed scan time of CTV was associated with better detection and more reliable characterization of BCS with IVC obstruction compared to a fixed delayed scan time.

2015-01-01

Full Text Available Backround/Aim. Anismus is paradoxal pressure increase or pressure decrease less than 20% of external anal sphincter during defecation straining. This study analyzed the presence of anismus as within a group of patients with the positive Rome III criteria for functional constipation. We used anorectal manometry as the determination method for anismus. Methods. We used anorectal waterperfused manometry in 60 patients with obstructive defecation defined by the Rome III criteria for functional constipation. We also analyzed anorectal function in 30 healthy subjects. Results. The presence of anismus is more frequent in the group of patients with obstructive defecation compared to the control group (a highly statistically significant difference, p < 0.01. Furthermore, we found that the Rome III criteria for functional constipation showed 90% accuracy in predicting obstructive defecation. We analyzed the correlation of anismus with the presence of weak external anal sphincter, rectal sensibility disorders, enlarged piles, diverticular disease and anatomic variations of colon. We found no correlation between them in any of these cases. Conclusion. There is a significant correlation between anismus and positive Rome III criteria for functional constipation. Anorectal manometry should be performed in all patients with the positive Rome III criteria for functional constipation.

In Europe, Defitelio (defibrotide) has a Market Authorization in curative treatment of severe sinusoidal obstruction syndrome (SOS) but not in prophylaxis (2013). In France, defibrotide has had a compassionate-use program since 2009. Today, the high cost of defibrotide remains a major hurdle for hospital budgets. Medicine and economic issues were evaluated for the 39 hospitals of the French Public Assistance-Hospitals of Paris (AP-HP). We analyzed literature reviews, consumption, and expenditures through AP-HP data in 2014 and patient profiles with defibrotide in the corresponding diagnostic-related groups (DRGs) and consulted a board of hematologists. Finally, 18 publications were selected. Between 2011 and 2014 consumption increased to €5.2M. In 2014, 80 patients receiving defibrotide were mainly ascribed to the DRG "hematopoietic stem cell transplantation" levels 3 or 4. The tariffs attributed to drugs (€3544 to 4084) cover a small part of treatment costs (€97,524 for an adult). French experts thus recommended a harmonization of indications in prophylaxis (off-label use), improvement of pretransplant care, and optimization of the number of vials used. The economic impact led experts to change their practices. They recommended the restriction of defibrotide use to SOS curative treatment and to high-risk situations in prophylaxis.

Rapunzel Syndrome: A Rare Postpartum Case

Directory of Open Access Journals (Sweden)

Teshome Tegene

2013-01-01

Full Text Available The Rapunzel syndrome describes a disorder in which a significant amount of hair is swallowed, forming a trichobezoar that extends past the stomach into the small intestines. Given the indigestible nature of hair, it subsequently leads to obstruction within the gastrointestinal system. Clinically, patients may present with symptoms of gastrointestinal obstruction, including abdominal complaints such as pain, nausea, vomiting, and diarrhea. However, due to its broad and nonspecific presenting symptoms, the diagnosis of Rapunzel syndrome warrants consideration once other common etiologies have been excluded. Surgical intervention is often required to remove the abdominal mass. This unusual syndrome is often associated with psychiatric disorders, affecting young women most commonly. In this report, we will discuss a unique case of Rapunzel syndrome in a one-month postpartum woman.

Chronic obstructive pulmonary disease and sleep related disorders.

Science.gov (United States)

Tsai, Sheila C

2017-03-01

Sleep related disorders are common and under-recognized in the chronic obstructive pulmonary disease (COPD) population. COPD symptoms can disrupt sleep. Similarly, sleep disorders can affect COPD. This review highlights the common sleep disorders seen in COPD patients, their impact, and potential management. Treatment of sleep disorders may improve quality of life in COPD patients. Optimizing inhaler therapy improves sleep quality. Increased inflammatory markers are noted in patients with the overlap syndrome of COPD and obstructive sleep apnea versus COPD alone. There are potential benefits of noninvasive positive pressure ventilation therapy for overlap syndrome patients with hypercapnia. Nocturnal supplemental oxygen may be beneficial in certain COPD subtypes. Nonbenzodiazepine hypnotic therapy for insomnia has shown benefit without associated respiratory failure or worsening respiratory symptoms. Melatonin may provide mild hypnotic and antioxidant benefits. This article discusses the impact of sleep disorders on COPD patients and the potential benefits of managing sleep disorders on respiratory disease control and quality of life.

The article deals with the problem of osteoporosis in patients with cardiovascular and broncho-obstructive disease. The risk factors and clinical functional features of osteoporosis are analyzed in patients with coronary heart disease, hypertension, chronic obstructive pulmonary disease, bronchial asthma. Indicators of bone mineral density in patients with cardiovascular and broncho-obstructive disease on average meet the criteria for osteopenia. Most examinees had a high risk of osteoporotic fractures as a result of significant reduction in bone mineral density. The presence of osteoporosis in patients with cardiovascular and broncho-obstructive pathology from the point of co-morbidity results in a syndrome of mutual aggravation that determines the need for a comprehensive diagnosis, treatment and prevention.

Obstructive sleep apnea syndrome (OSAS) is a common disorder that can lead to cardiovascular morbidity and mortality, as well as to metabolic, neurological, and behavioral consequences. It is currently believed that nasal obstruction compromises the quality of sleep when it results in breathing disorders and fragmentation of sleep. However, recent studies have failed to objectively associate sleep quality and nasal obstruction. The aim of this systematic review is to evaluate the influence of nasal obstruction on OSAS and polysomnographic indices associated with respiratory events. Eleven original articles published from 2003 to 2013 were selected, which addressed surgical and non-surgical treatment for nasal obstruction, performing polysomnography type 1 before and after the intervention. In most trials, nasal obstruction was not related to the apnea-hypopnea index (AHI), indicating no improvement in OSAS with reduction in nasal resistance. However, few researchers evaluated other polysomnography indices, such as the arousal index and rapid eye movement (REM) sleep percentage. These could change with nasal obstruction, since it is possible that the nasal obstruction does not completely block the upper airways, but can increase negative intrathoracic pressure, leading to sleep fragmentation.

Inflammatory cardiovascular risk markers in obstructive sleep apnoea syndrome.

LENUS (Irish Health Repository)

Ryan, Silke

2012-02-01

Obstructive sleep apnoea syndrome (OSAS) represents a highly prevalent disease and is recognized as a major public health burden. Large-scale epidemiological studies have demonstrated an independent relationship between OSAS and various cardiovascular disorders. The pathogenesis of cardiovascular complications in OSAS is not completely understood, but given the complexity of the disorder, a multifactorial etiology is likely. Inflammatory processes have emerged as critical in the pathogenesis of atherosclerosis in general and they mediate many of the stages of atheroma formation. Circulating levels of several markers of inflammation have been associated with future cardiovascular risk. These markers include cell adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1) and selectins, cytokines such as tumour necrosis factor alpha (TNF-alpha) and interleukin 6 (IL-6), chemokines such as IL-8, and C-reactive protein (CRP). There is increasing evidence that inflammatory processes also play a central role in the cardiovascular pathophysiology of OSAS. This is supported by cell culture and animal studies identifying a preferential activation of inflammatory pathways by intermittent hypoxia (IH), the hallmark of OSAS. A number of studies have selectively examined the expression of inflammatory factors in OSAS patients with different conclusions. These different findings may have been contributed to by a number of methodological factors such as small subject numbers, inadequately matched study populations, particularly in terms of body mass index (BMI), and inclusion of patients with pre-existing cardiovascular or metabolic diseases. This review will focus on the potential role of various inflammatory markers in OSAS with a critical analysis of the current literature.

Feeding and defecation behavior of Triatoma rubida (Uhler, 1894) (Hemiptera: Reduviidae) under laboratory conditions, and its potential role as a vector of Chagas disease in Arizona, USA.

Chagas disease is caused by the parasite Trypanosoma cruzi, which is transmitted to humans by blood-sucking triatomine insects. This disease is endemic throughout Mexico and Central and South America, but only a few autochthonous cases have been reported in the United States, despite the fact that infected insects readily invade houses and feed on humans. Competent vectors defecate during or shortly after feeding so that infective feces contact the host. We thus studied the feeding and defecation behaviors of the prevalent species in southern Arizona, Triatoma rubida. We found that whereas defecation during feeding was frequent in females (93%), it was very rare in immature stages (3%), and absent in males. Furthermore, more than half of the immature insects that exhibited multiple feeding bouts (62%) defecated during interruptions of feeding, i.e., while likely on or near the host. These results indicate that T. rubida potentially could transmit T. cruzi to humans.

Tamayo Martínez, Nathalie; Rosselli Cock, Diego

Obstructive sleep apnea syndrome (OSAS) is a condition associated with multiple negative outcomes. People with mental illness might be at increased risk of having it, given that medication given has adverse effects on weight and there are alterations in sleep associated with them; however, there are few studies in this population. Describe the patients and the results of polysomnography ordered based on clinical symptoms in a psychiatric outpatient clinic between 2012 and 2014. A case series in which medical records were evaluated. 58 patients who underwent polysomnography, 89% of them had OSAS, 16% were obese and 19% were been treated with benzodiazepines. This is a condition that must be considered during the clinical evaluation of patients with mental illness, since its presence should make clinicians think about drug treatment and follow up.

Recognizing sleep-disordered breathing is on the rise every year. Manifestations, such as snoring, that were earlier considered mere inconvenients are now acquiring greater importance concerning life quality and social impact. To compare the clinical history to polysomnogram (PSG) results in the Obstructive Sleep Apnea/Hypopnea Syndrome (OSAHS). 125 patients were analyzed, in a retrospective study. Specific questionnaires, avaliations of Body Mass Index and Epworth Scale were carried out. Among the patients, 75 were males and 50 were females. The main symptom was snoring. 46% had normal PSG, 30% had light OSAHS, 15% moderate and 9% severe OSAHS and it was not observed a correlation between clinical data and PSG results. Concerning clinical symptoms, only insomnia has shown relevance when univariably analyzed in normal and light OSAHS patients (plosing its importance when analyzed together with other factors. the clinical history, per se, is not sufficient to define OSAHS' diagnosis or it's severity.

Full Text Available Untreated obstructive sleep apnea-hypopnea syndrome (OSAHS is associated with significant direct and indirect medical costs. This disorder also has a significant negative impact on work performance and safety, and is implicated in a substantial proportion of motor vehicular crashes. Timely diagnosis and optimal therapy have shown a lower utilization rate related to health care systems and reduced costs, while adverse risks are mitigated at the same time. Prompt diagnosis and optimal therapy have shown to decrease heath care utilizaton and costs, as well as mitigating these adverse risks. Similarly, untreated OSAHS is associated with higher unemployment rates. For health care professionals, having a patient with OSAHS involved in a MVC is of paramount importance for a several reasons, including personal and public damage, as well as the potential physical disability that may be caused by the accident. In Latin America, measuring direct and indirect costs is necessary considering the public health problem associated with OSAHS and the implications mentioned above.

Effects of Adenotonsillectomy on Neurocognitive Function in Pediatric Obstructive Sleep Apnea Syndrome

2014-01-01

Full Text Available Obstructive sleep apnea syndrome (OSAS in children does not only present with symptoms of sleep disturbances but also with associated symptoms such as growth failure, enuresis, academic learning difficulties, and behavioral problems, including attention deficit/hyperactivity disorder- (ADHD- like symptoms. We evaluated neurocognitive functions before and after adenotonsillectomy in a patient with OSAS. An 11-year-old boy suspected of having ADHD with nocturnal enuresis was referred for evaluation. He was found to have adenotonsillar hypertrophy. Presence of snoring was evident only after detailed medical interview. Polysomnography confirmed the diagnosis of OSAS, which was subsequently treated by adenotonsillectomy. The apnea/hypopnea index decreased from 21.9 at baseline to 1.8 after surgery, and the frequency of enuresis fell from almost nightly to 2-3 times per month. Neurocognitive and behavioral assessment after the treatment of OSAS showed significant improvement in cognitive functions, especially attention capacity and considerable amelioration of behavioral problems including ADHD-like symptoms. As the most common cause of pediatric OSAS is adenotonsillar hypertrophy, medical interview and oropharyngeal examination should always be performed in children suspected of having ADHD. The necessity of sleep evaluation for children with ADHD-like symptoms was also emphasized.

The aim of this systematic literature review was to assess the impact of obstructive sleep apnea syndrome (OSAS) on patients' occupational health. We selected 19 studies that dealt with issues related to job performance and productivity, absenteeism, and psychosocial health of patients with OSAS and assessed the risk of bias in their conclusions. Although methodologically rigorous studies are needed to confirm these findings, the results obtained suggest the existence of multiple relationships between OSAS and work limitations of patients (i.e., difficulties maintaining attention, learning new tasks, or performing monotonous tasks). The studies reviewed reached more scientifically consistent conclusions about such patients' risk of taking more days of sick leave or having work disability, particularly if they reported excessive daytime sleepiness. Very few studies have explored the relationship between OSAS and psychosocial occupational health of patients. Thus, there is a need for research to clarify these aspects of occupational medicine. OSAS has numerous effects on patients' occupational health, yet, in general, results should be confirmed by studies with sufficiently large samples in which OSAS is diagnosed with reliable methods and occupational variables are assessed with standardized and validated questionnaires.

2013-12-01

Full Text Available Objective: Obstructive sleep apnea syndrome (OSAS is characterized by recurrent upper airway obstruction and intermittent hypoxia during sleep. Intermittent hypoxia and increased inflammatory activity plays a role in increased risk of cardiovascular disease in the OSAS. OSAS is an important cause of morbidity and mortality and cardiovascular disorders are the most important complications of OSAS. Mean platelet volume (MPV is a marker of platelet activation and function, and increased platelet volume is associated with increased platelet activity. Different diseases related with inflammation, hypoxia, vascular injury, thrombosis and atherosclerosis were found to be associated with MPV. In this study, we aimed to investigate the relationship between OSAS and MPV. Methods: In this retrospective study, data of sex and age matched 33 patients with moderate OSAS, 34 patients with severe OSAS and 30 healthy subjects were evaluated. Results: The mean MPV was found in control, moderate OSAS and severe OSAS groups as 7.83±1.00, 8.26±1.40 and 8.94±1.20 (fL respectively. The mean MPV value was significantly higher in severe OSAS group than control subjects (p=0.001. In correlation analysis, there were positive correlation between MPV with apnea-hypopnea index and total sleep time, and negative correlation between MPV with platelet count and minimum oxygen saturation (Respectively, p=0.003 / R=0.295, p=0.030 / R=0.221, p=0.011 / R= -0.257, p=0.019 / R= -0.238. Conclusion: In this study, the increased MPV was associated with severe OSAS and the results of this study suggest that the platelet activation is increased in OSAS. Hypoxia caused by OSAS, due to the activated platelets, may play a role in the development of cardiovascular diseases which is an important cause of morbidity and mortality in OSAS.

2010-11-01

Full Text Available Abstract Introduction Cases of gallstone ileus account for 1% to 4% of all instances of mechanical bowel obstruction. The majority of obstructing gallstones are located in the terminal ileum. Less than 10% of impacted gallstones are located in the duodenum. A gastric outlet obstruction secondary to a gallstone ileus is known as Bouveret syndrome. Gallstones usually enter the bowel through a biliary enteral fistula. Little is known about the formation of such fistulae in the course of gallstone disease. Case presentation We report the case of a 72-year-old Caucasian woman born in Germany with a gastric outlet obstruction due to a gallstone ileus (Bouveret syndrome, with a large gallstone impacted in the third part of the duodenum. Diagnostic investigations of our patient included plain abdominal films, gastroscopy and abdominal computed tomography, which showed a biliary enteric fistula between the gallbladder and the duodenal bulb. Our patient was successfully treated by laparotomy, duodenotomy, extraction of the stone, cholecystectomy, and resection of the fistula in a one-stage surgical approach. Histopathological examination showed chronic and acute cholecystitis, with perforated ulceration of the duodenal wall and acute purulent inflammation of the surrounding fatty tissue. Four months prior to developing a gallstone ileus our patient had been hospitalized for cholecystitis, a large gallstone in the gallbladder, cholangitis and a small obstructing gallstone in the common biliary duct. She had been treated with endoscopic retrograde cholangiopancreatography, endoscopic biliary sphincterotomy, balloon extraction of the common biliary duct gallstone, and intravenous antibiotics. At the time of her first presentation, abdominal ultrasound and endoscopic examination (including esophagogastroduodenoscopy and endoscopic retrograde cholangiopancreatography had not shown any evidence of a biliary enteral fistula.

Full Text Available Objectives: The present retrospective study analyzes sagittal cephalometric changes in patients affected by obstructive sleep apnea syndrome submitted to maxillomandubular advancement. Material and Methods: 15 adult sleep apnea syndrome (OSAS patients diagnosed by polysomnography (PSG and treated with maxillomandubular advancement (MMA were included in this study. Pre- (T1 and postsurgical (T2 PSG studies assessing the apnea/hypopnea index (AHI and the lowest oxygen saturation (LSAT level were compared. Lateral cephalometric radiographs at T1 and T2 measuring sagittal cephalometric variables (SNA, SNB, and ANB were analyzed, as were the amount of maxillary and mandibular advancement (Co-A and Co-Pog, the distance from the mandibular plane to the most anterior point of the hyoid bone (Mp-H, and the posterior airway space (PAS.Results: Postoperatively, the overall mean AHI dropped from 58.7 ± 16 to 8.1 ± 7.8 events per hour (P < 0.001. The mean preoperative LSAT increased from 71% preoperatively to 90% after surgery (P < 0.001. All the patients in our study were successfully treated (AHI < 20 or reduced by 50%. Cephalometric analysis performed after surgery showed a statistically significant correlation between the mean SNA variation and the decrease in the AHI (P = 0.01. The overall mean SNA increase was 6°.Conclusions: Our findings suggest that the improvement observed in the respiratory symptoms, namely the apnea/hypopnea episodes, is correlated with the SNA increase after surgery. This finding may help maxillofacial surgeons to establish selective criteria for the surgical approach to sleep apnea syndrome patients.

2007-02-01

Colonic J-pouch-anal anastomosis or colonic side-to-end anastomosis is the reconstruction of choice after low anterior resection. However, the mechanisms of defecation after both reconstruction forms are still speculative. Low anterior rectal resections were performed in 12 dogs with six colonic J-pouch-anal (pouch) and six coloanal side-to-end (SE) reconstructions. Four months postoperative stool frequency, intestinal transit time, and neorectal compliance were determined by radiography and barostat. Defecation mechanisms were evaluated radiographically during expulsion of artificial stool. One dog with pouch reconstruction could not be evaluated due to an anastomotic leak, while the others had uncomplicated course. Spontaneous stool frequency was significantly increased with both reconstruction methods (control 2.0+/-0.9, pouch 2.7+/-1.2, SE 3.3+/-0.9 day; panastomosis. Our results show that pouch evacuation is passive and independent from pouch motility. The functional principle of the colonic J-pouch is not its reservoir function but a delay of colonic motility.

For this purpose, 435 patients with PT with signs of BOS (forced expiratory volume at 1 second (FEV1) 70% of the normal values; 2) 229 patients with FEV1 69-50%; 3) 102 patients with FEV1 bronchial obstructive syndrome in patients with pulmonary tuberculosis was highly effective, promotes the amelioration of the degree of respiratory symptoms in patients with IPT by 2 to 8 times, in those with FCPT by more than 2-3 times, and in those with PS by 1.45-10 times. The differences in the efficiency of bronchodilator therapy depend on the baseline level of bronchial obstruction. In patients with pulmonary tuberculosis concurrent with BO, the use of current inhalation bronchodilator therapy results in a substantial increase in FEV1, which differentiates BOS in PT from COLD. The use of the proposed therapy in the multimodality treatment of patients with pulmonary tuberculosis showed no statistically significant differences in the changes in the degree of X-ray symptoms while this therapy permits acceleration of abacillation in patients with IPT by 16.8% and in those with FCPT by 14.8%. Effective bronchodilator therapy considerably enhances life quality in patients. Thus, early systematic and long-term performance of the bronchodilator therapy, based on the principles of bronchodilator therapy for COLD, in patients with PT concurrent with BOS may substantially enhance the efficiency of treatment in this category of patients.

The transient left ventricular apical ballooning syndrome, also known as Takotsubo cardiomyopathy, is characterized by transient left ventricular dysfunction in the absence of obstructive epicardial coronary disease. Although the syndrome has been reported in Japan since 1990, it is rare in other regions. Rapid recognition of the syndrome can modify the diagnostic and therapeutic attitude i.e. avoiding thrombolysis and performing catheterization in the acute phase. (author)

Although previous studies demonstrated that patients with obstructive sleep apnea syndrome (OSAS) may present subclinical manifestations of dysphagia, in not one were different textures and volumes systematically studied. The aim of this study was to analyze the signs and symptoms of oropharyngeal dysphagia using fiberoptic endoscopic evaluation of swallowing (FEES) with boluses of different textures and volumes in a large cohort of patients with OSAS. A total of 72 OSAS patients without symptoms of dysphagia were enrolled. The cohort was divided in two groups: 30 patients with moderate OSAS and 42 patients with severe OSAS. Each patient underwent a FEES examination using 5, 10 and 20 ml of liquids and semisolids, and solids. Spillage, penetration, aspiration, retention, and piecemeal deglutition were considered. The penetration-aspiration scale (PAS), pooling score (PS), and dysphagia outcome and severity scale (DOSS) were used for quantitative analysis. Each patient completed the SWAL-QOL questionnaire. Forty-six patients (64 %) presented spillage, 20 (28 %) piecemeal deglutition, 26 (36 %) penetration, and 30 (44 %) retention. No differences were found in the PAS, PS, and DOSS scores between patients with moderate and severe OSAS. Patients with severe OSAS scored higher General Burden and Food selection subscales of the SWAL-QOL. Depending on the DOSS score, the cohort of patients was divided into those with and those without signs of dysphagia. Patients with signs of dysphagia scored lower in the General Burden and Symptoms subscales of the SWAL-QOL. OSAS patients show signs of swallowing impairment in about half of the population; clinicians involved in the management of these patients should include questions on swallowing when taking the medical history.

To evaluate peculiarities of a clinical course and changes in bronchial mucosa in bronchial asthma (BA) patients with chronic obstructive pulmonary disease (COPD) in combination with hyperoxaluria (HOU); informative value of some laboratory and device findings including oxalates assay in bronchial lavage fluid for specification of the diagnosis, role of oxalates in development of obstructive syndrome and choice of optimal therapy. Oxalates were examined in daily urine, bronchoalveolar lavage fluid and exhaled air condensate of 104 patients with BA and COPD, 77 of which had HOU and an atypical course of bronchial obstruction syndrome. Conception of airways inflammation in patients with oxalate metabolism disturbances is proposed. It is shown that insoluble oxalates participate in pathogenesis of bronchial obstruction. Oxalate metabolism disturbances are an important factor in pathogenesis of airways inflammation and development of bronchial obstruction in predisposed patients. Therefore, administration of insoluble oxalates lowering therapy may effectively prevent formation and progression of obstructive pulmonary diseases in this group of patients.

This is a case of a 59-year-old woman with Bouveret syndrome. An initial endoscopic approach to management is described. Gallstone ileus occurs when a gallstone passes from a cholecystoduodenal fistula or a choledochoduodenal fistula into the gastrointestinal tract and causes obstruction, usually at the ileocecal valve. Bouveret syndrome is a variant of gallstone ileus where the gallstone lodges in the duodenum or pylorus causing a gastric outlet obstruction. The endoscopic and surgical management of this process are important to keep in mind and may be evolving as endoscopic therapies improve.

Dynamic graciloplasty (DGP) improves anal continence and quality of life for most patients. However, in some patients, DGP fails and fecal incontinence is unsolved or only partially improved. Constipation is also a significant problem after DGP, occurring in 13-90%. Colonic irrigation can be considered as an additional or salvage treatment for defecation disorders after unsuccessful or partially successful DGP. In this study, the effectiveness of colonic irrigation for the treatment of persistent fecal incontinence and/or constipation after DGP is investigated. Patients with defecation disorders after DGP visiting the outpatient clinic of the University Hospital Maastricht were selected for colonic irrigation as additional therapy or salvage therapy in the period between January 1999 and June 2003. The Biotrol(R) Irrimatic pump or the irrigation bag was used for colonic irrigation. Relevant physical and medical history was collected. The patients were asked to fill out a detailed questionnaire about colonic irrigation. Forty-six patients were included in the study with a mean age of 59.3 +/- 12.4 years (80% female). On average, the patients started the irrigation 21.39 +/- 38.77 months after the DGP. Eight patients started irrigation before the DGP. Fifty-two percent of the patients used the irrigation as additional therapy for fecal incontinence, 24% for constipation, and 24% for both. Irrigation was usually performed in the morning. The mean frequency of irrigation was 0.90 +/- 0.40 times per day. The mean amount of water used for the irrigation was 2.27 +/- 1.75 l with a mean duration of 39 +/- 23 min. Four patients performed antegrade irrigation through a colostomy or appendicostomy, with good results. Overall, 81% of the patients were satisfied with the irrigation. Thirty-seven percent of the patients with fecal incontinence reached (pseudo-)continence, and in 30% of the patients, the constipation completely resolved. Side effects of the irrigation were

Iliac vein compression syndrome (also known as May-Thurner syndrome or Cockett's syndrome) is a rare clinical entity in which the left common iliac vein is compressed when it passes between the right common iliac artery and the spine. The sustained compression and trauma caused by the pulsatile force of the artery on the vein damage the intima and lead to the formation of membranes or bands in the vascular lumen that hinder or obstruct the flow of blood in the vein, favoring thrombus formation. The current treatment strategy of choice is endovascular vein patch angioplasty and stenting with the aim of improving the caliber of the lumen and enabling normal venous drainage. We present two cases of May-Thurner syndrome and review the clinical and CT findings. Copyright © 2011 SERAM. Published by Elsevier Espana. All rights reserved.

Obstructive sleep apnea-hypopnea syndrome and cognitive impairments in the elderly

Full Text Available Obstructive sleep apnea-hypopnea syndrome (OSAHS is a common sleep-related breathing disorder that is associated with significant morbidity and mortality. It has received increasing attention that neurocognitive deficits occur with a high frequency in OSAHS. However, it is rarely known that OSAHS impacts on cognition in the elderly in whom an increased prevalence of OSAHS is present. In this review we consider recent studies in the association between OSAHS and cognitive impairments, with specific interest in the older population. Firstly, we elucidate the characteristics of OSAHS and OSAHS-related cognitive impairments in the older patients. Many studies have showed that the prevalence of OSAHS increases with age and it is higher in the elderly than other population. Moreover, OSAHS is associated with higher incidence of comorbidities and increased risk of clinical deterioration in the elderly, especially the neurocognitive impairments which even can develop dementia. Subsequently, we discuss the possible reasons of cognitive impairments that caused or aggravated by OSAHS in the elderly. The intermittent hypoxia (IH-related disturbances of homeostasis such as oxidative stress, inflammation, and age-related changes such as the changes of sleep architecture, the declined expression level of anti-aging gene, medical comorbidities and polypharmacy, may be both contribute to the increased risk of cognitive impairments in the older patients with OSAHS.

Children with the obstructive sleep apnea syndrome (OSAS) have impaired responses to hypercapnia, subatmospheric pressure, and inspiratory resistive loading during sleep. This may be due, in part, to an impairment in the afferent limb of the upper airway sensory pathway. Therefore, we hypothesized that children with OSAS had diminished upper airway sensation compared to controls. Case-control. Academic hospital. Subjects with OSAS aged 6-16 years, and age- and BMI-matched controls. Two-point discrimination (TPD) was measured during wakefulness with modified calipers in the anterior tongue, right interior cheek, and hard palate. Thirteen children with OSAS and 9 controls were tested. The age (mean +/- SD) for OSAS and controls was 11 +/- 4 vs. 13 +/- 2 years (NS); OSAS BMI Z score 2.4 +/- 0.5, controls 2.2 +/- 0.5 (NS); OSAS apnea hypopnea index 31 +/- 48, controls 0.4 +/- 0.5 events/hour (P Children with OSAS had impaired TPD in the anterior tongue (median [range]) = 9 [3-14] mm, controls 3 [1-7], P = 0.002) and hard palate (OSAS 6 [3-9] mm, controls 3 [1-4], P children with OSAS during wakefulness. We speculate that this impairment might be due to a primary sensory function abnormality or secondary to nerve damage and/or hypoxemia caused by OSAS. Further studies after treatment of OSAS are needed.

Obstructive sleep apnea (OSA) is a recurrent episode of partial or complete upper airway obstruction during sleep despite ongoing respiratory efforts and is implicated as the risk factor of cardiovascular disease. The OSA syndrome is typified by recurring partial or total occlusion of the pharynx, sleep fragmentation, episodes of gasping, and, eventually, daytime sleepiness. If it is left untreated, OSA syndrome can cause hypertension, coronary artery disease congestive heart disease, insulin resistance and death. In this review, we describe the pathogenesis and diagnosis of OSA. We also focused on the continuous positive airway pressure (CPAP) as the main therapy for OSA. CPAP has been shown to provide benefit for not only respiratory system, but also for cardiovascular system and metabolic system. Finally, we discussed briefly about the issue of adherence of using CPAP that could contribute to lower compliant in patient with OSA.

2016-01-01

The morbidity and mortality of obstructive sleep apnea-hypopnea syndrome (OSAHS) are regarded as consequences of its adverse effects on the cardiovascular system. Chronic intermittent hypoxia (CIH) induced by OSAHS can result in vascular endothelial injury, thus promoting development of atherosclerosis (AS). Studies have shown that CIH is an independent risk factor for the occurrence and development of AS, but the underlying mechanism remains unclear. Here, we review clinical and fundamental studies reported during the last 10 years on the occurrence and development of AS mediated by CIH, focusing on inflammation, oxidative stress, insulin resistance, cell apoptosis, vascular endothelial injury, platelet activation, and neuroendocrine disorders. This review will offer current evidence and perspective to researchers for the development of effective intervention strategies for OSAHS-related cardiocerebrovascular diseases.

Obstructive sleep apnoea syndrome is associated with significant morbidity. A high prevalence of obstructive sleep apnoea (OSA) symptoms has been reported in patients with asthma and chronic obstructive pulmonary disease (COPD). There are limited studies regarding relationship between atopy and OSA. To study the risk of obstructive sleep apnoea among middle aged chronic obstructive pulmonary disease and asthma patients by a home based sleep study and its association with atopy. Patients with asthma and COPD were evaluated for OSA symptoms by Epworth sleepiness scale (ESS) and Berlin questionnaire (BQ). ESS score > or = 9 was considered as high risk for OSA. Patients having high risk for OSA by ESS and BQ were further evaluated for OSA by home based sleep study. Skin prick test against common allergens was done to diagnose atopy in these patients. Among 400 patients (229, 57.25% male and 171, 42.75% female) 328 were asthmatics and 72 were COPD patients. ESS and BQ was positive in 11.25% (45/400) and 18.25% (73/400) patients respectively. ESS was positive in 10.67% (35/328) of asthma and 13.88% (10/72) of COPD patients. BQ was positive in 18.29% (60/328) of asthmatic and 18.05% (13/72) of COPD patients. Skin prick test was positive in 74.16% patients. The maximum positivity was found in asthmatics (139/155, 89.68%) compared to COPD patients (16/155, 10.32%). Skin prick test was done for 40 patients out of 73 of Asthma and COPD patients who were found positive by ESS and BQ. 72.5% patients were found to be atopic. Out of 19 patients in whom home polysomnography was done, 13 patients consented for skin prick test with common aeroallergens and 9 (69.23%) patients were found to be atopic. There is an increased risk of obstructive sleep apnoea among middle aged chronic obstructive pulmonary disease and asthma patients. Atopy could be associated with OSA. The association needs to be proved in a larger study.

BACKGROUND The objective of the present study was to investigate whether the analysis of magnesium (Mg), high-sensitivity C-reactive protein (hsCRP), and ischemia-modified albumin (IMA) concentrations can be used as a non-invasive and convenient method for diagnosing obstructive sleep apnea syndrome (OSAS). MATERIAL AND METHODS After polysomnography, venous blood was collected from 33 patients with OSAS and 30 control individuals. Serum levels of Mg, hsCRP, and IMA were investigated. The relationship between these factors and apnea-hypopnea index (AHI) was analyzed using the Pearson correlation coefficient. The role of the factors was determined using a receiver operating characteristic (ROC) curve and multivariate logistic regression analysis. RESULTS The levels of hsCRP and IMA were significantly higher in patients with OSAS than in control subjects, while the levels of Mg were lower (PMIh, which is obtained by multivariate analysis, yielded an AUC value of 0.93 (0.83-0.98). Continuous positive airway pressure (CPAP) treatment reversed the changes in the serum levels of Mg, hsCRP, and IMA. CONCLUSIONS Patients with OSAS show reduced serum Mg levels and elevated serum hsCRP and IMA levels. These observed alterations can be reversed by CPAP treatment. A novel model, named MIh, may be a promising tool for OSAS diagnosis.

Obstructive sleep apnea syndrome (OSAS) is associated with cardiovascular diseases, in particular systemic arterial hypertension. We postulated that intermittent nocturnal hypoxia in OSAS may be associated to decreased fractional exhaled nitric oxide (FENO) levels from distal airspaces. Multiple flow rate measurements have been used to fractionate nitric oxide (NO) from alveolar and bronchial sources in 34 patients with OSAS, in 29 healthy control subjects, and in 8 hypertensive non-OSAS patients. The effect of 2 days of treatment with nasal continuous positive airway pressure (nCPAP) on FENO was examined in 18 patients with severe OSAS. We found that the mean [+/- SE] concentrations of exhaled NO at a rate of 50 mL/s was 21.8 +/- 1.9 parts per billion (ppb) in patients with OSAS, 25.1 +/- 3.3 ppb in healthy control subjects, and 15.4 +/- 1.7 ppb in hypertensive control patients. The mean fractional alveolar NO concentration (CANO) in OSAS patients was significantly lower than that in control subjects (2.96 +/- 0.48 vs 5.35 +/- 0.83 ppb, respectively; p bronchial FENO, is impaired in patients with OSAS and that this impairment is associated with an increased risk of hypertension. NO production within the alveolar space is modified by treatment with nCPAP.

Full Text Available Background and Objective This study aimed to investigate objective and subjective continuous positive airway pressure (CPAP compliance in patients with obstructive sleep apnea syndrome (OSAS. Moreover, we evaluated the factors and benefits associated with good CPAP compliance. Methods Subjects were 153 OSAS patients who underwent polysomnography for CPAP titration. Subjective compliance was defined as reported CPAP use of at least 4 hours a day for five or more days per week, and objective compliance was defined as CPAP use of at least 4 hours a day for more than 70% of the time recorded in the CPAP machine. Results The subjective and objective compliance rates were 34.0% and 20.7%, respectively. Subjectively compliant patients had lower minimum O2 saturation and higher % of time with O2 saturation lower than 90% than did patients declining CPAP treatment. Objectively compliant patients had lower insomnia and depression score and lower minimum O2 saturation than did patients declining CPAP treatment. Daytime sleepiness and subjective sleep quality improved to the same extent in both objectively and subjectively compliant patients. Conclusions Lower insomnia score and more severe OSA correlate with good CPAP compliance. CPAP effect was comparable between subjectively and objectively compliant patients.

Full Text Available Abstract Introduction This is the first case report of Mirizzi syndrome associated with hepatic artery pseudoaneurysm. Case presentation A 54-year-old man presented with painful obstructive jaundice and weight loss. Computed tomography showed a hilar mass in the liver. Following an episode of haemobilia, angiography demonstrated a pseudoaneurysm of a branch of the right hepatic artery that was embolised. At surgery, a gallstone causing Mirizzi type II syndrome was found to be responsible for the biliary obstruction and a necrotic inflammatory mass and haematoma were found to be extending into the liver. The mass was debrided and drained, the obstructing stones removed and the bile duct drained with a t-tube. The patient made a full recovery. Conclusion This case highlights another situation where there may be difficulty in differentiating Mirizzi syndrome from biliary tract cancer.

Chronic obstructive pulmonary disease is the fourth leading cause of mortality worldwide. It is defined as a persistent airflow limitation usually progressive and not fully reversible to treatment. The diagnosis of chronic obstructive pulmonary disease and severity of disease is confirmed by spirometry. Chronic obstructive pulmonary disease produces electrical changes in the heart which shows characteristic electrocardiogram pattern. The aim of this study was to observe and evaluate diagnostic values of electrocardiogram changes in chronic obstructive pulmonary disease patients with no other comorbidity. We analyzed 110 electrocardiogram findings in clinically stable chronic obstructive pulmonary disease patients and evaluated the forced expiratory volume in the first second, ratio of forces expiratory volume in the first second to the fixed vital capacity, chest radiographs and electrocardiogram changes such as p wave height, QRS axis and voltage, right bundle branch block, left bundle branch block, right ventricular hypertrophy, T wave inversion in leads V1-V3, S1S2S3 syndrome, transition zone in praecordial lead and QT interval. We found electrocardiogram changes in 64% patients, while 36% had normal electrocardiogram. The most frequent electrocardiogram changes observed were transition zone (76.36%) low QRS (50%) and p pulmonale (14.54%). Left axis deviation was observed in 27.27% patients. Diagnostic values of electrocardiogram in patients with chronic obstructive pulmonary disease suggest that chronic obstructive pulmonary disease patients should be screened electrocardiographically in addition to other clinical investigations.

Megacystis Microcolon Intestinal Hypoperistalsis Syndrome is a quite rare congenital anomaly that presents with a functional obstruction of the gastrointestinal tract which is usually fatal. It is three to four times more prevalent in females. We present a case of a rare association of a male neonate with Megacystis Microcolon Intestinal Hypoperistalsis Syndrome who in addition had the classical triad of Prune Belly Syndrome and thus suggest a possibility of different spectrums with a common pathogenesis.

The prevalence, profiles, and potential risk factors of snoring and obstructive sleep apnea-hypopnea syndrome (OSAHS) in China are largely unknown. This study aims to investigate the prevalence, profiles, and potential risk factors for snoring and OSAHS in Guangxi, China, and the association between OSAHS and ethnicity. Urban and rural population-based cluster samples were randomly selected in each of eight counties/cities. All residents aged 14 years or older in the selected clusters were interviewed using a standardized questionnaire. A subject was considered to have clinically diagnosed OSAHS if snoring was loud and habitual, breathing pauses were observed, and the subject experienced excessive daytime sleepiness. Among 12,742 sampled subjects, 10,819 completed the questionnaire (response rate = 84.9%). The overall OSAHS prevalence was 4.1% (men, 5.7% (5.1-6.3%); women, 2.4% (2.0-2.9%); Zhuang people, 3.2% (2.8-3.7%); Han people 6.0% (5.2-6.8%).The overall rate of habitual snoring was 11.5 % (men, 17.1% (16.1-18.1%); women, 5.6% (5.0-6.2%)). Univariate analysis showed that the OSAHS prevalence was significantly higher among the following groups: urban residents, elderly individuals, smokers, drinkers, those with higher body mass indexes (BMI), those with more years of schooling, those with nasal problems, those whose parents are Han, and those who usually sleep in prone position. However, multiple logistic regression analysis revealed that only urban residency, age, smoking status, drinking status, and BMI were the risk factors for OSAHS. OSAHS is prevalent in individuals aged 14 years or older in Guangxi, China. Han and Zhuang people differ significantly in their obstructive sleep apnea (OSA) prevalence, but this difference is explained by the combination of classic OSA risk factors.

The purpose of this study was to determine the effects of obstructive sleep apnea syndrome (OSAS) on the submacular and peripapillary retinal nerve fiber layer (RNFL) and choroidal thickness (ChT). Eighty-four eyes of 42 male patients with OSAS and 112 eyes of 56 aged-matched and body mass index-matched healthy male subjects were enrolled in this case-control study. The ChT and peripapillary RNFL thickness was measured using enhanced depth imaging optical coherence tomography. The ChT and RNFL thickness measurements of the groups were compared, and correlations among the Apnea Hypopnea Index (AHI) values and these measurements were calculated. Right and left eyes were separately evaluated. There were no significant differences in the subfoveal and temporal ChT between the groups (p > 0.05). The OSAS group had significantly thicker ChT at 0.5 and 1.5 mm nasal to the fovea in both eyes than the control group (p 0.05). Between AHI and mean RNFL thickness showed a median negative correlation (r = - 0.411, p = 0.001). The choroidal thickening in patients with OSAS may be associated with the pathophysiology of the neurodegeneration process of the disease.

Hepatic veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is an unpredictable condition associated with endothelial-cell damage due to conditioning for hematopoietic stem-cell transplantation (HSCT) or chemotherapy without HSCT. Mortality in patients with VOD/SOS and multi-organ dysfunction (MOD) may be >80%. Areas covered: Defibrotide is the only approved drug for the treatment of severe hepatic VOD/SOS after HSCT in the European Union and hepatic VOD/SOS with renal or pulmonary dysfunction in the United States. Its efficacy in patients with VOD/SOS with MOD post-HSCT was demonstrated in a clinical-trial program that included a historically controlled treatment study, a phase 2 trial, and a large T-IND expanded-access program that also included patients without MOD and who received chemotherapy without HSCT. Expert commentary: Defibrotide appears to protect endothelial cells and restore the thrombolytic-fibrinolytic balance. It addresses a significant clinical need and has demonstrated favorable Day +100 survival and overall adverse-event rates that seem similar to control groups receiving supportive care alone. Currently, defibrotide is under investigation for the prevention of VOD/SOS in high-risk pediatric and adult patients.

Sinusoidal obstruction syndrome (SOS) (formerly known as hepatic veno-occlusive disease (VOD)) is a life-threatening complication subsequent to hematopoietic stem cell transplantation. However, no completely satisfactory strategies for the treatment of SOS have been established yet. Defibrotide is a single-stranded polydeoxyribonucleotide with anti-thrombotic, anti-ischemic, anti-inflammatory and thrombolytic properties, but without systemic anticoagulant effects, and some encouraging results have been reported in western countries. We treated four patients with defibrotide for SOS, since there seemed to be no possibility to cure the patients with conventionally available treatments in Japan. All patients showed evidence of multiple organ failure at the start of the treatment. Defibrotide was administered intravenously in normal saline in four divided doses for 14 to 27 days. Three patients (75%) responded to the therapy, while one died of SOS and cytomegalovirus infection despite intensive therapy. None of the patients suffered from significant adverse effects such as severe hemorrhage. This is the first report dealing with the treatment with defibrotide of Japanese patients with SOS. Because defibrotide is considered to be promising for the treatment of SOS, it is important to start a phase II study as soon as possible.

Kleine–Levin Syndrome: A case report

Full Text Available The Kleine–Levin Syndrome is a differential diagnosis for patients with diurnal excessive sleepiness and a suspicion of narcolepsy. It is characterized by paroxysmal attacks of diurnal excessive sleepiness, associated with one or more symptoms of hyperphagia, hypersexuality, coprolalia and copropraxia. During crisis intervals, there are no symptoms. This pathology predominantly manifests itself in teenagers, being more frequent among males. The course of this disease is unpredictable, with variable duration and frequency. The most accepted physiopathology is that of a hypothalamic dysfunction, although and recently, there has appeared a hypothesis of a post-infectious autoimmune disorder. These patients show an elevated body mass index, which can predispose to association with comorbidities such as the sleep obstructive apnea syndrome. Treatment involves medications with different effects, but there is no specific and effective therapy. Our article shows a classic case of Kleine–Levin Syndrome associated with sleep obstructive apnea syndrome, a rare association in the literature.

To provide a comprehensive review of studies on information processing speed in patients with obstructive sleep apnea syndrome (OSAS) as compared to healthy controls and normative data, and to determine whether continuous positive airway pressure (CPAP) treatment improves information processing speed. A systematic review was performed on studies drawn from Medline and PsycINFO (January 1990-December 2011) and identified from lists of references in these studies. After inclusion criteria, 159 articles were left for abstract review, and after exclusion criteria 44 articles were fully reviewed. The number of patients in the studies reviewed ranged from 10 to 157 and the study samples consisted mainly of men. Half of the studies reported that patients with OSAS showed reduced information processing speed when compared to healthy controls. Reduced information processing speed was seen more often (75%) when compared to norm-referenced data. Psychomotor speed seemed to be particularly liable to change. CPAP treatment improved processing speed, but the improvement was marginal when compared to placebo or conservative treatment. Patients with OSAS are affected by reduced information processing speed, which may persist despite CPAP treatment. Information processing is usually assessed as part of other cognitive functioning, not as a cognitive domain per se. However, it is important to take account of information processing speed when assessing other aspects of cognitive functioning. This will make it possible to determine whether cognitive decline in patients with OSAS is based on lower-level or higher-level cognitive processes or both. © 2013 John Wiley & Sons A/S.

We examined the risk factors for automobile accidents caused by falling asleep while driving in subjects with obstructive sleep apnea syndrome (OSAS). We asked licensed drivers with history of snoring and excessive daytime sleepiness who had undergone polysomnography (PSG) at the Department of Sleep Medicine/Sleep Disorders Center at Aichi Medical University Hospital to complete the questionnaires on accidents caused by falling asleep while driving. As a subjective measure of sleepiness, we used the Epworth sleepiness scale (ESS). Based on PSG results, 2387 subjects diagnosed with OSAS were divided into three groups according to apnea-hypopnea index (AHI): mild-to-moderate (5 ≤ AHI accidents in the past 5 years due to falling asleep. Our multivariate analysis suggests that scores on the ESS and patient-reported frequency of feeling drowsy while regular driving and working are related to automobile accidents caused by falling asleep while driving.

The concept of veno-occlusive disease (VOD), along with our understanding of it, has historically been and remains an evolving phenomenon. This review presents a broad view of VOD, also known as sinusoidal obstruction syndrome (SOS), including (1) traditional hematopoietic stem cell transplant-associated VOD/SOS, (2) late-onset VOD/SOS, (3) pulmonary VOD, and (4) VOD/SOS associated with chemotherapy only. Several VOD/SOS management modalities exist that include modes for both prophylaxis and treatment. An extensive review of the literature on monoclonal antibodies, both approved and pending approval by the US Food and Drug Administration, reveals that only a few have been associated with an increased risk for VOD/SOS. In fact, bevacizumab appears to have a protective effect against the development of VOD/SOS. As the landscape of cancer treatment changes, careful attention needs to be focused on how new therapies affect the incidence of VOD/SOS.

To determine the influence of manipulations aimed at increasing the transdiaphragmatic pressure gradient on the gastro-esophageal junction (GEJ) of dogs with brachycephalic airway obstructive syndrome (BAOS), and to identify the manipulation that most improves the detection of GEJ abnormalities and sliding hiatal hernia (SHH) in dogs with BAOS. In vivo experimental pilot study and prospective clinical study. Five purpose-bred Beagles and 20 dogs diagnosed with BAOS. Respiratory and digestive clinical signs as well as respiratory and GEJ abnormalities were scored. The presence of SHH was investigated using radiography and endoscopy in standard conditions. Endoscopic investigation was repeated after manipulations including manual pressure on the cranial abdomen (MP), Trendelenburg position (30°), or temporary complete endotracheal tube obstruction (ETO). No SHH was detected in any normal dog under any condition. Sixty-five percent of dogs with BAOS presented with digestive clinical signs, including vomiting and/or regurgitation. SHH was observed in only one dog via radiography and was not detected via endoscopy. Manipulations during endoscopy influenced GEJ abnormalities and allowed the detection of SHH in 2 (30°), 4 (ETO), and 5 (MP) dogs, respectively. Digestive clinical signs correlated with GEJ abnormalities observed only in dogs with ETO (P = .02). Manipulations aimed at increasing the transdiaphragmatic pressure gradient during endoscopy in BAOS dogs allowed the detection of GEJ abnormalities and SHH that were not detected under standard conditions. Although MP allowed detection of SHH in more dogs than ETO, scores under MP did not correlate with digestive clinical signs. Therefore, ETO may be more accurate manipulation for the detection of GEJ abnormalities in BAOS dogs. © 2017 The American College of Veterinary Surgeons.

Obstructive respiratory disorders during sleep present an important medical and social problem. Serious dysfunctions of cardiovascular, nervous, endocrine and other vital systems of the body reduce longevity and life quality. On the other hand, load nocturnal snore and abnormal during sleepiness cause great damage to family life, reduce working capacity and induce accidents. X-ray visualization of the upper airways is essential in diagnosing obstructive upper airway states and selecting patients for surgical treatment. The paper presents the author's own experience in using various X-ray diagnostic methods in patients with chronic snore and obstructive sleep apnoea-hypopnoea syndrome [ru

Diaphragmatic electromyogram was recorded during NREM sleep in 4 patients affected by obstructive sleep apnoea (OSA) syndrome in order to evaluate the behaviour of expiratory time (TE) in the course of the obstructive apnoea-ventilation cycle. The two components of TE, i.e. time of post-inspiratory inspiratory activity (TPIIA) and time of expiratory phase 2 (TE2) were separately analysed. TPIIA showed a short duration, with only minor variations, within the apnoea, while its duration was more variable and longer in the interapnoeic periods: the longest TPIIA values were associated with the highest inspiratory volumes in the same breaths. This behaviour seemed regulated according to the need of a more or less effective expiratory flow braking, probably as a result of pulmonary stretch receptors discharge. Conversely TE2 showed a continuous gradual modulation, progressively increasing in the pre-apnoeic period, decreasing during the apnoea and increasing in the post-apnoeic period: these TE2 variations seemed related to oscillations in chemical drive. These data show that TE in the obstructive apnoea-ventilation cycle results from a different modulation in its two components and suggest that both mechanical and chemical influences play a role in its overall duration.

Full Text Available ntroduction: Considering the high prevalence of obstructive sleep apnea syndrome (OSAS and its complications, proper diagnosis and treatment is particularly important. Since the standard diagnostic test for OSAS is polysomnography, which is not widely available, finding a simple, available, and cheap diagnostic method is very helpful. The aim of this study was to evaluate the efficiency of anterior rhinomanometry and upper respiratory tract examination in diagnosis of the OSAS. Materials and Methods: In this observational analytic study, all patients referred to BAMDAD sleep clinic for polysomnography from Feb 2007 to Jul 2007 were evaluated by anterior rhinomanometry as well as upper respiratory tract examination and results were compared with each other. Results: Of 66 patients participated in our study, 31 patients were in the normal group, 19 in mild apnea group, and 16 in moderate to severe apnea group. The results of ENT examination showed clear obstruction in 22 patients. 12 of them were in moderate to severe apnea group, and 9 of them in mild apnea group. Only one patient with abnormal examination was in the normal group. The respiratory tract resistance which was measured by anterior rhinomanometry showed no significant association with positive results of polysomnography. Conclusion: Our study showed that although anterior rhinomanometry is invalid for diagnosis of OSAS, ENT examination (such as noctural oxymetry can be a useful diagnostic method for OSAS.

Poor sanitation is thought to be a major cause of enteric infections among young children. However, there are no previously published randomized trials to measure the health impacts of large-scale sanitation programs. India's Total Sanitation Campaign (TSC) is one such program that seeks to end the practice of open defecation by changing social norms and behaviors, and providing technical support and financial subsidies. The objective of this study was to measure the effect of the TSC implemented with capacity building support from the World Bank's Water and Sanitation Program in Madhya Pradesh on availability of individual household latrines (IHLs), defecation behaviors, and child health (diarrhea, highly credible gastrointestinal illness [HCGI], parasitic infections, anemia, growth). We conducted a cluster-randomized, controlled trial in 80 rural villages. Field staff collected baseline measures of sanitation conditions, behaviors, and child health (May-July 2009), and revisited households 21 months later (February-April 2011) after the program was delivered. The study enrolled a random sample of 5,209 children village with improved sanitation facilities as defined by the WHO/UNICEF Joint Monitoring Programme by an average of 19% (95% CI for difference: 12%-26%; group means: 22% control versus 41% intervention), decreased open defecation among adults by an average of 10% (95% CI for difference: 4%-15%; group means: 73% intervention versus 84% control). However, the intervention did not improve child health measured in terms of multiple health outcomes (diarrhea, HCGI, helminth infections, anemia, growth). Limitations of the study included a relatively short follow-up period following implementation, evidence for contamination in ten of the 40 control villages, and bias possible in self-reported outcomes for diarrhea, HCGI, and open defecation behaviors. The intervention led to modest increases in availability of IHLs and even more modest reductions in open

A 21-year-old male developed significant swelling of his tongue after a respiratory arrest. The patient had a history of Hurler\\'s syndrome. Magnetic resonance imaging (MRI) angiogram delineated that the swelling was due to compression of his internal jugular veins at the level of the first rib, resulting in thoracic inlet obstruction. The standard surgical treatment of thoracic inlet obstruction was not suitable in this patient\\'s case due to his short thick neck and his characteristic Hurler\\'s syndrome body habitus. Therefore, a novel surgical strategy was used to decompress his head and neck vessels. The manubrium was widened using an iliac crest bone graft, stabilised using internal fixation plates and reconstructed with a pectoral muscle flap.

Full Text Available Background: Obstructive sleep apnea syndrome (OSAS is a common sleep disorder characterized by repeated upper airway obstruction during sleep. While respiratory pauses followed by loud snoring and daytime sleepiness are the main symptoms of OSAS, the patients may complain from sleep disruption, headache, mood disturbance, irritability, and memory impairment. However, the association of sleep apnea with anxiety and depression is not completely understood. Adherence to continuous positive airway pressure (CPAP, the treatment of choice for OSAS, may be influenced by psychological conditions, especially claustrophobia. The aim of this study was to evaluate the association of OSAS with anxiety and depression symptoms. This study also investigated the association of anxiety with body mass index (BMI and the severity of OSAS. Materials and Methods: We conducted a cross-sectional study on 178 adult individuals diagnosed with OSAS at the sleep laboratory between September 2008 and May 2012. The participants were interviewed according to a checklist regarding both their chief complaints and other associated symptoms. The psychological status was assessed according to Beck anxiety inventory (BAI and Beck depression inventory (BDI scoring. The severity of breathing disorder was classified as mild, moderate, and severe based on apnea-hypopnea index (AHI which was ascertained by overnight polysomnography. Daytime sleepiness was assessed by Epworth sleepiness scale (ESS. Results: The mean (SD age of participants was 50.33 years. In terms of sex, 85.5% of the study population were males and14.4% were females. We found no relation between sex and the symptoms of OSAS. Regarding the frequency of anxiety and depression symptoms, 53.9% of the individuals had some degree of anxiety, while 46.1% demonstrated depressive symptoms. In terms of OSAS severity, this study showed that OSAS severity was associated with the frequency of anxiety, chocking, and sleepiness (P

METHODS: A cross-sectional study was conducted on patients with typical angina and positive exercise tolerance test undergoing coronary angiography in our center. 342 consecutive patients with CSX were enrolled into this study and were matched regarding age and sex with 342 patients with acute coronary syndrome (ACS and also 342 patients with chronic stable angina (SA. Cardiovascular risk factors as well as biochemistry profile of the patients were recorded. RESULTS: Mean age of the studied patients was 53.0 years and 41.5% were male. There was no significant difference between the CSX patients and CAD patients regarding body mass index (BMI. Frequency of diabetes mellitus, hyperlipidemia, smoking, family history of premature CAD and hypertension was significantly lower in patients with CSX than ACS and SA patients. Patients with CSX had significantly higher levels of high-density lipoprotein cholesterol (HDL-cholesterol than comparators while the levels of low-density lipoprotein cholesterol (LDL-cholesterol, total cholesterol, triglyceride and fasting blood sugar (FBS were significantly lower in patients with CSX than CAD patients. CONCLUSION: The present study demonstrated that CSX patients had substantially lower frequency of all conventional CVD risk factors than patients with obstructive CAD. This might aid in developing novel scoring systems or appropriateness criteria for angiographic evaluation of patients with typical angina and positive exercise test in order to reduce the rate of negative results.   Keywords: Cardiac Syndrome X, Microvascular Dysfunction

Roles and Mechanisms of Obstructive Sleep Apnea-Hypopnea Syndrome and Chronic Intermittent Hypoxia in Atherosclerosis: Evidence and Prospective

Directory of Open Access Journals (Sweden)

Linqin Ma

2016-01-01

Full Text Available The morbidity and mortality of obstructive sleep apnea-hypopnea syndrome (OSAHS are regarded as consequences of its adverse effects on the cardiovascular system. Chronic intermittent hypoxia (CIH induced by OSAHS can result in vascular endothelial injury, thus promoting development of atherosclerosis (AS. Studies have shown that CIH is an independent risk factor for the occurrence and development of AS, but the underlying mechanism remains unclear. Here, we review clinical and fundamental studies reported during the last 10 years on the occurrence and development of AS mediated by CIH, focusing on inflammation, oxidative stress, insulin resistance, cell apoptosis, vascular endothelial injury, platelet activation, and neuroendocrine disorders. This review will offer current evidence and perspective to researchers for the development of effective intervention strategies for OSAHS-related cardiocerebrovascular diseases.

Hepatic Sinusoidal Obstruction Syndrome During Chemotherapy for Childhood Medulloblastoma: Report of a Case and Review of the Literature

2014-01-01

Hepatic sinusoidal obstruction syndrome (HSOS), also known as veno-occlusive disease, is a well-recognized toxic complication after autologous and allogeneic hematopoietic stem cell transplant, during treatment of Wilms tumor and rhabdomyosarcoma associated with actinomycin-D, and during acute lymphoblastic leukemia therapy due to oral 6-thioguanine. However, its occurrence in the context of chemotherapy regimens for other childhood malignancies is rare. We report a 5-year-old girl with high-risk anaplastic medulloblastoma, who developed severe HSOS during her second cycle of maintenance chemotherapy, consisting of vincristine, cisplatin, and cyclophosphamide. She was treated with defibrotide with complete resolution of the HSOS. These findings and a review of the literature, highlight the occurrence of HSOS in children outside the established settings of hematopoietic stem cell transplantation, Wilms tumor, rhabdomyosarcoma, and acute lymphoblastic leukemia.

Leptin is a hormone with well-investigated functions concerning body composition, energy homeostasis and feeding behavior in humans. The obstructive sleep apnea syndrome (OSAS) is strongly associated with obesity, which is known to be closely associated with hyperleptinemia. More recently, ghrelin, a hormone that also influences appetite and energy homeostasis, has been discovered. The aim of this study was to investigate serum leptin and ghrelin levels in obese patients with OSAS in comparison with equally obese controls without OSAS. Thirty untreated obese patients with moderate-severe OSAS (apnea-hypopnea index: AHI > or =15) and 22 obese controls (AHI <5) were studied. To confirm the diagnosis, all patients underwent standard polysomnography in our sleep disorders center. Serum samples were taken at 08:00 h in the morning after overnight fasting. Significantly higher serum leptin levels were found in OSAS patients compared to controls (p = 0.012), but there was no significant difference in serum ghrelin levels between OSAS patients and controls. Serum leptin levels were significantly correlated with body mass index in both OSAS patients (r = 0.55, p = 0.002) and controls (r = 0.46, p = 0.028), but only in OSAS patients was the leptin level significantly correlated with AHI (r = 0.38, p = 0.036). These data support findings suggesting that leptin is a hormonal factor affected by OSAS and not determined by obesity alone. Further studies are needed to investigate the relationship between serum ghrelin and OSAS. (c) 2005 S. Karger AG, Basel

Sinusoidal obstruction syndrome (SOS) is a frequent, troubling, and potentially fatal complication of hematopoietic stem cell transplantation. Despite promising results with defibrotide (DF), no treatment has been established as standard. DF is a single-stranded polydeoxyribonucleotide, obtained from controlled depolymerization of porcine intestinal mucosal cells. It has antithrombotic, antiischemic, antiinflammatory, and thrombolytic properties without significant side effects. We retrospectively evaluated the charts of 80 consecutive patients, with 89 hematopoietic stem cell transplants for hematologic malignancies. The results of early initiation of DF treatment in 14 patients with SOS are presented in this study. Fourteen patients, 8 males and 6 females % median age 40.5 years (range, 16-46 years) were diagnosed to have SOS. Disease severity was classified as severe in 6 (42.85%), moderate in 4 (28.57%), and mild in 4 (28.57%) patients. We treated 14 patients with DF for a median of 21.5 days (range, 4-39 days). All 14 patients received DF after the diagnosis of SOS. Three patients with severe and all of the patients with mild to moderate SOS responded to treatment with complete resolution of SOS-related signs and symptoms. All patients responding to DF were alive at 100 days posttransplantation. There was no significant drug-related side effect among patients treated with DF. With an overall response rate of 78.56% and a 50% complete response rate in severe SOS cases and minimal side effects, we suggest that DF is the best available agent to treat SOS.

Superior Vena Cava Syndrome due to Thrombosis: A Rare Paraneoplastic Presentation of Bronchogenic Carcinoma

Directory of Open Access Journals (Sweden)

Avradip Santra

2016-07-01

Full Text Available Superior vena cava (SVC syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable state, e.g., malignancy. Here, an unusual case of sudden onset SVC syndrome has been reported, which on initial radiologic evaluation was found to have a lung nodule without any significant mediastinal mass or adenopathy compressing SVC. Subsequent investigation with Doppler ultrasonography of the neck showed thrombosis in the right internal jugular, right subclavian and right brachiocephalic vein, which was responsible for SVC syndrome. Histopathological evaluation of lung nodule confirmed presence of an adenocarcinoma. Therefore, venous thromboembolism as a paraneoplastic syndrome should be kept in mind while evaluating a case of SVC obstruction in a cancer patient. Management of the underlying disease is of prime importance in such cases and anticoagulation is the mainstay of therapy. Ability to identify paraneoplastic syndrome may have a significant effect on clinical outcome, ranging from early diagnosis to improved quality of life of the patient.

BACKGROUND: Hepatic sinusoidal obstruction syndrome (SOS) during treatment of childhood acute lymphoblastic leukemia (ALL) has mainly been associated with 6-thioguanine. The occurrence of several SOS cases after the introduction of extended pegylated asparaginase (PEG-asparaginase) therapy...... in the Nordic Society of Paediatric Haematology and Oncology (NOPHO) ALL2008 protocol led us to hypothesize that PEG-asparaginase, combined with other drugs, may trigger SOS during 6-thioguanine-free maintenance therapy. PROCEDURE: In children with ALL treated in Denmark according to the NOPHO ALL2008 protocol...... children receiving PEG-asparaginase biweekly, 29 developed SOS (≥2 criteria: hyperbilirubinemia, hepatomegaly, ascites, weight gain ≥2.5%, unexplained thrombocytopenia

We examined 28 children aged from 5 months to 6 years. The average age of the patients was 33.7 months (95% CI 24.5–43.0. Viruses have been identified in 75 % of patients. In 39.3 % we found bocavirus. Metapneumovirus was detected in 10.7 % of patients. Exacerbation of bronchial asthma 2.3 times more likely was associated with bocavirus infection compared to patients with obstructive bronchitis (RR = 2.3 (95% CI 0.9–6.2. Duration of bronchoobstructive syndrome in children with bronchial asthma was significantly higher (p < 0.0001 than in children with obstructive bronchitis — 5.3 days (95% CI 4.1–6.4 versus 2.7 days (95% CI 2.3–3.1. The findings confirm a significant role of viral infection and new respiratory viruses in causing bronchoobstructive syndrome in children.

A series of 9 patients of a mean age of 48 years, operated on for compression of the ilio-femoral venous axis is reported. The cause of obstruction was external compression in 3 cases, a retroperitoneal sarcoma in 1 case, and an infrarenal aortic aneurysm in 2. Two patients presented with a Cockett's syndrome, 3 with a chronic ilio-femoral thrombosis, and one with a post-traumatic segmentary stenosis. Treatment consisted in a resection/Dacron grafting of 2 infrarenal aortic aneurysms, one femoro-caval bypass graft, 2 transpositions of the right common iliac artery in the left hypogastric artery for Cockett's syndrome, 3 Palma's operations for chronic thrombosis, and one internal jugular vein interposition for segmentary stenosis. There were no postoperative deaths and no early thromboses of venous reconstructions performed. All the patients were relieved of symptoms during the follow-up period, whose mean length was 38 months. The cause of venous obstruction and the presence of symptoms which are resistant to medical treatment are the main indications to ilio-femoral venous revascularization. The choice of the optimal treatment in each single case yields satisfactory results.

Williams syndrome is characterized by obstructive aortopathy attributable to heterozygous loss of ELN , the gene encoding elastin. Lesions are thought to result primarily from excessive smooth muscle cell (SMC) proliferation and consequent medial expansion, although an initially smaller caliber and increased stiffness of the aorta may contribute to luminal narrowing. The relative contributions of such abnormalities to the obstructive phenotype had not been defined. We quantified determinants of luminal stenosis in thoracic aortas of Eln -/- mice incompletely rescued by human ELN . Moderate obstruction was largely because of deficient circumferential growth, most prominently of ascending segments, despite increased axial growth. Medial thickening was evident in these smaller diameter elastin-deficient aortas, with medial area similar to that of larger diameter control aortas. There was no difference in cross-sectional SMC number between mutant and wild-type genotypes at multiple stages of postnatal development. Decreased elastin content was associated with medial fibrosis and reduced aortic distensibility because of increased structural stiffness but preserved material stiffness. Elastin-deficient SMCs exhibited greater contractile-to-proliferative phenotypic modulation in vitro than in vivo. We confirmed increased medial collagen without evidence of increased medial area or SMC number in a small ascending aorta with thickened media of a Williams syndrome subject. Deficient circumferential growth is the predominant mechanism for moderate obstructive aortic disease resulting from partial elastin deficiency. Our findings suggest that diverse aortic manifestations in Williams syndrome result from graded elastin content, and SMC hyperplasia causing medial expansion requires additional elastin loss superimposed on ELN haploinsufficiency. © 2017 American Heart Association, Inc.

Based on basic treatment of blood glucose regulation, warming acupuncture was applied at Pishu (BL 20), Shenshu (BL 23), Guanyuanshu (BL 26), Zusanli (ST 36), Chongyang (ST 42), Quchi (LI 11) and Hegu (LI 4) in the warming acupuncture group, while acupuncture was applied at the identical acupoints in the conventional acupuncture group. Both the treatments were given once a day with an interval of one day every six days; totally the treatment was given for 4 weeks. The TCM symptom score, Toronto clinical scoring system (TCSS) and nerve conduction velocity (NCV) before and after treatment were compared in the two groups. After treatment, the TCM symptom scores in the two groups were significantly reduced (both P nervus peroneus communis, as well as sensory nerve of tibial nerve and sural nerve was improved in the warming acupuncture group (all P 0.05). Warming acupuncture and conventional acupuncture could both increase TCM symptom score, improve NCV in patients of DPN with syndrome of yang deficiency and cold coagulation, obstruction of collaterals and blood stasis; warming acupuncture has advantage in symptom improvement.

The hot spot on liver scan was demonstrated by many authors in various conditions such as SVC obstruction, Budd-Chiari syndrome, liver abscess, hemangioma of liver, hepatic venoocclusive diseases, IVC obstruction, and tricuspid insufficiency. And the appearance of hot spot in SVC obstruction is due to unusual collateral circulation. But there was no report of this hots pot on liver scan in our country. We have recently observed one patient with SVC obstruction who shows well-defined area of increased radioactivity between right and left lobe of liver on liver scan using 99m Tc-tin colloid, and demonstrated collateral circulations with RI venography using 99m Tc-O 4 . The injection site of radiocolloid was left antecubital vein. This hot spot did not appear when the radiocolloid was injected into right leg vein. We report here this hoe spot on liver scan in SVC obstruction with review of some literatures.

Full Text Available Abstract Background and objectives: Children with Down Syndrome are vulnerable to significant upper airway obstruction due to relative macroglossia and dynamic airway collapse. The objective of this study was to compare the upper airway dimensions of children with Down Syndrome and obstructive sleep apnea with normal airway under dexmedetomidine sedation. Methods: IRB approval was obtained. In this retrospective study, clinically indicated dynamic sagittal midline magnetic resonance images of the upper airway were obtained under low (1 mcg/kg/h and high (3 mcg/kg/h dose dexmedetomidine. Airway anteroposterior diameters and sectional areas were measured as minimum and maximum dimensions by two independent observers at soft palate (nasopharyngeal airway and at base of the tongue (retroglossal airway. Results and conclusions: Minimum anteroposterior diameter and minimum sectional area at nasopharynx and retroglossal airway were significantly reduced in Down Syndrome compared to normal airway at both low and high dose dexmedetomidine. However, there were no significant differences between low and high dose dexmedetomidine in both Down Syndrome and normal airway. The mean apnea hypopnea index in Down Syndrome was 16 ± 11. Under dexmedetomidine sedation, children with Down Syndrome and obstructive sleep apnea when compared to normal airway children show significant reductions in airway dimensions most pronounced at the narrowest points in the nasopharyngeal and retroglossal airways.

To describe the CT and MRI features of hepatic sinusoidal obstruction syndrome (HSOS) caused by herbal medicine Gynura segetum. The CT and MRI features of 16 consecutive Gynura segetum induced HSOS cases (12 men, 4 women) were analyzed. Eight patients had CT; three patients had MRI, and the remaining five patients had both CT and MRI examinations. Based on their clinical presentations and outcomes, the patients were classified into three categories: mild, moderate, and severe. The severity of the disease was also evaluated radiologically based on the abnormal hepatic patchy enhancement in post-contrast CT or MRI images. Ascites, patchy liver enhancement, and main right hepatic vein narrowing or occlusion were present in all 16 cases. Hepatomegaly and gallbladder wall thickening were present in 14 cases (87.5%, 14/16). Periportal high intensity on T2-weighted images was present in 6 cases (75%, 6/8). Normal liver parenchymal enhancement surrounding the main hepatic vein forming a clover-like sign was observed in 4 cases (25%, 4/16). The extent of patchy liver enhancement was statistically associated with clinical severity classification (kappa = 0.565). Ascites, patchy liver enhancement, and the main hepatic veins narrowing were the most frequent signs of herbal medicine induced HSOS. The grade of abnormal patchy liver enhancement was associated with the clinical severity.

Disorders of the pelvic floor and anal sphincters; a gastroenterologist’s perspective

Directory of Open Access Journals (Sweden)

Eamonn M.M. Quigley, MD FRCP FACP FACG FRCPI

2013-03-01

Full Text Available The integration and coordination of the musculature of the pelvic floor and the anal sphincters is critical to two important physiological functions: defecation and continence. Consequently, disorders affecting the pelvic floor muscles, the anal sphincters, their innervation or their precise coordination will, depending on their nature, result either in obstructed defecation or fecal incontinence. Both of these disorders are much more common in females and the latter, in particular, is linked with parity. While the symptomatology, presentation and optimal mode of investigation of fecal incontinence are well standardized, considerable debate and controversy continues to surround the contributions of pelvic floor and anal sphincter dysfunction to chronic constipation and the optimal clinical approach to their investigation remains to be defined. In appropriately chosen cases surgical intervention may provide the best outcome for sufferers from incontinence; biofeedback approaches may be of value in both incontinence and obstructed defecation and surgery has little role to play in the latter.

Neurobiology of Depression and Irritable Bowel Syndrome Comorbidity

Full Text Available Irritable bowel syndrome is a disabling functional disorder with a frequent comorbidity of depression though underlying mechanisms remain yet little understood. Various signs and symptoms have been determined as diagnostic criteria in recent years and standardized as Rome-III criteria. Irritable bowel syndrome can have constipation-dominant, diarrhea-dominant or mixed clinical presentations. Main features can be summarized as continuous and recurrent abdominal pain or discomfort associated with a change of stool frequency or consistency and usually relief of symptoms with defe-cation in the absence of physical or laboratory abnormalities indicative of an organic etiology. The frequency of major depressive disorder diagnosis reaches up to two thirds of irritable bowel syndrome patients. Moreover, the comorbidity of irritable bowel syndrome among patients with major depression is highly frequent (30%. The mechanism underlying irritable bowel syndrome which have been considered as a kind of a somatization disorder for a long time and now as a functional bowel disease is in the brain-gut axis. Low grade mucosal inflammation and cytokines originating from mucosal inflammation have important functions in the pathophysiology of irritable bowel syndrome and its comorbidity with major depression. Besides the inflammatory factors lumbosacral visceral hyperexcitability which is an individual variation is proposed as the main underlying cause of irritable bowel syndrome. Visceral hyper-excitability is mediated by cytokines and neuro-mediators and stress is known to increase the effect of this mechanism. Furthermore, molecules participating in this mechanism (e.g. cytokines, corticotrophin releasing factor, neurokinins and monoamines play important roles in the pathophysiology of depression. Increased activation in the pain matrix (thalamus – insula – prefrontal cortex and insufficiency of endogenous pain inhibitory system are regarded as possible

Obstructive sleep apnea (OSA) occurs commonly in the U.S. population and is seen in both obese as well as non-obese individuals. OSA is a disease characterized by periodic upper airway collapse during sleep, which then results in either apnea, hypopnea, or both. The disorder leads to a variety of medical complications. Neuropsychiatric complications include daytime somnolence, cognitive dysfunction, and depression. Increased incidence of motor vehicle accidents has been documented in these patients and probably reflects disordered reflex mechanisms or excessive somnolence. More importantly, vascular disorders such as hypertension, stroke, congestive cardiac failure, arrhythmias, and atherosclerosis occur frequently in these patients. The lungs may be affected by pulmonary hypertension and worsening of asthma. Recent data from several laboratories demonstrate that obstructive sleep apnea is characterized by an inflammatory response. Cytokines are elaborated during the hypoxemic episodes leading to inflammatory responses as marked clinically by elevated C-reactive protein (CRP). As elevated CRP levels are considered markers of the acute phase response and characterize progression of vascular injury in coronary artery disease, it is likely that obstructive sleep apnea could lead to worsening of vasculopathy. Moreover, as inflammatory mechanisms regulate bronchial asthma, it is also likely that cytokines and superoxide radicals generated during hypoxemic episodes could exacerbate reactive airway disease. Patients with Cough, Obstructive sleep apnea, Rhinosinusitis, and Esophageal reflux clustered together can be categorized by the acronym, "CORE", syndrome. The purpose of this manuscript is to review the inflammatory responses that occur in patients with obstructive sleep apnea and relate them to the occurrence of cardiopulmonary disease.

Obesity in children is assumed to serve as a major risk factor in pediatric obstructive sleep apnea syndrome (OSAS). However, the prevalence of OSAS in otherwise healthy obese children from the community is unknown. To determine the prevalence of OSAS in obese children identified and recruited from primary care centers. A cross-sectional, prospective, multicenter study. Spanish children ages 3-14 y with a body mass index (BMI) greater than or equal to the 95th percentile for age and sex were randomly selected, and underwent medical history, snoring, and Pediatric Sleep Questionnaire (PSQ) assessments, as well as physical examination, nasopharyngoscopy, and nocturnal polysomnography (NPSG) recordings. Two hundred forty-eight children (54.4% males) with mean age of 10.8 ± 2.6 y were studied with a BMI of 28.0 ± 4.7 kg/m(2) corresponding to 96.8 ± 0.6 percentile when adjusted for age and sex. The mean respiratory disturbance index (RDI), obstructive RDI (ORDI), and obstructive apnea-hypopnea index (OAHI) were 5.58 ± 9.90, 5.06 ± 9.57, and 3.39 ± 8.78/h total sleep time (TST), respectively. Using ≥ 3/h TST as the cutoff for the presence of OSAS, the prevalence of OSAS ranged from 21.5% to 39.5% depending on whether OAHI, ORDI, or RDI were used. The prevalence of obstructive sleep apnea syndrome (OSAS) in obese children from the general population is high. Obese children should be screened for the presence of OSAS.

Sinusoidal obstruction syndrome (SOS) is a serious complication of hematopoietic stem cell transplantation (HSCT), with a mortality rate of up to 90%. We report our experience on the use of defibrotide for SOS prophylaxis in HSCT. We retrospectively reviewed data of 49 patients who received defibrotide as SOS prophylaxis during the course of HSCT at the National Cancer Center, Goyang, Korea, between August 2005 and July 2008. Thirty-four patients (69.4%) were classified as a high-risk group for developing SOS. Defibrotide was well-tolerated, without any grade 3 or 4 toxicity. The median value of maximum total bilirubin within 100 days after HSCT was within the normal range. SOS was diagnosed in only 1 patient, who underwent autologous HSCT due to relapsed medulloblastoma. There was no day 100 treatment-related mortality in our study. Defibrotide appears to be a safe prophylaxis for SOS. This study suggests that it could be effective to use prophylactic defibrotide in advance to improve HSCT outcomes in patients at risk of SOS.

Role of Oxidative Stress in the Neurocognitive Dysfunction of Obstructive Sleep Apnea Syndrome

Li Zhou

2016-01-01

Full Text Available Obstructive sleep apnea syndrome (OSAS is characterized by chronic nocturnal intermittent hypoxia and sleep fragmentations. Neurocognitive dysfunction, a significant and extraordinary complication of OSAS, influences patients’ career, family, and social life and reduces quality of life to some extent. Previous researches revealed that repetitive hypoxia and reoxygenation caused mitochondria and endoplasmic reticulum dysfunction, overactivated NADPH oxidase, xanthine oxidase, and uncoupling nitric oxide synthase, induced an imbalance between prooxidants and antioxidants, and then got rise to a series of oxidative stress (OS responses, such as protein oxidation, lipid peroxidation, and DNA oxidation along with inflammatory reaction. OS in brain could trigger neuron injury especially in the hippocampus and cerebral cortex regions. Those two regions are fairly susceptible to hypoxia and oxidative stress production which could consequently result in cognitive dysfunction. Apart from continuous positive airway pressure (CPAP, antioxidant may be a promising therapeutic method to improve partially reversible neurocognitive function. Understanding the role that OS played in the cognitive deficits is crucial for future research and therapeutic strategy development. In this paper, recent important literature concerning the relationship between oxidative stress and cognitive impairment in OSAS will be summarized and the results can provide a rewarding overview for future breakthrough in this field.

Aging is associated with an increase in the prevalence of obstructive sleep apnea syndrome (OSAS) as well as the shortening of telomeres. It is known that OSAS-related factors are stimuli that can contribute to the acceleration of cellular senescence. Thus, the present study aimed to compare the leukocyte telomere length (LTL) between OSAS patients and controls, as well as to verify the correlation between LTL and sleep parameters. We used DNA extracted of 928 individuals from EPISONO to measure the LTL by the quantitative real-time polymerase chain reaction. All individuals were subjected to one full-night polysomnography. LTL was significantly shorter in OSAS patients compared to controls. The results showed negative correlations between LTL and the following variables: apnea-hypopnea index, respiratory disturbance index, desaturation index and wake after sleep onset. LTL was positively correlated with sleep efficiency, total sleep time, basal, minimum and maximum oxygen saturation. Lastly, it was observed that OSAS severity was associated with shorter LTL even after adjusting for sex, age, years of schooling, body mass index, diabetes, stroke and heart attack. In conclusion, our study indicates the presence of an association between LTL and OSAS and a significant impact of severity of OSAS in telomeres shortening.

In this study, examined were prevalence of asymptomatic cerebrovascular disease (ACD) in patients with obstructive sleep apnea syndrome (OSAS) and relationship between its severity and ACD prevalence. Subjects were 192 cases (M 170/F 20, av. age 50.6 y) with chief complaint of snore, sleep apnea (apnea-hypopnea index/AHI 0-118.4/h), midday drowsiness and so on without CD history, who underwent the overnight polysomnographic recording, vascular risk assessment like life habits, blood pressure and impaired GT, and brain MRI. The last item was conducted with Siemence 1.5T machine to get T1-, T2-weighted and FLAIR images to evaluate asymptomatic lacunar infarction (ALI) and periventricular hyperintensity (PVH). Light (AHI<15/h), moderate (15≤AHI<30) and severe (AHI≥30) OSASs were found in 44, 35 and 61 cases, respectively. ALIs were found in 7 light, 17 moderate and 61 severe cases and PVH, in 9, 19 and 61 cases, respectively. Thus it was revealed that patients with moderate to severe OSAS had complication of ACD in a higher rate than those with light OSAS and that prevalence of ACD was higher in OSAS patients with AHI 15/h or more.

Oxaliplatin is an important chemotherapeutic agent, used in the treatment of hepatic colorectal metastases, and known to induce the sinusoidal obstruction syndrome (SOS). Pathophysiological knowledge concerning SOS is based on a rat model. Therefore, the aim was to perform a comprehensive study of the features of human SOS, using both light microscopy (LM) and electron microscopy (EM). Included were all patients of whom wedge liver biopsies were collected during a partial hepatectomy for colorectal liver metastases, in a 4-year period. The wedge biopsy were perfusion fixated and processed for LM and EM. The SOS lesions were selected by LM and details were studied using EM. Material was available of 30 patients, of whom 28 patients received neo-adjuvant oxaliplatin. Eighteen (64%) of the 28 patients showed SOS lesions, based on microscopy. The lesions consisted of sinusoidal endothelial cell detachment from the space of Disse on EM. In the enlarged space of Disse a variable amount of erythrocytes were located. Sinusoidal endothelial cell detachment was present in human SOS, accompanied by enlargement of the space of Disse and erythrocytes in this area. These findings, originally described in a rat model, were now for the first time confirmed in human livers under clinically relevant settings. Copyright © 2016 Elsevier Ltd. All rights reserved.

Chronic constipation affects more than 17% of the global population worldwide, and up to 50% of patients were outlet obstruction constipation (OOC). Women and the elderly are most likely to be affected, due to female-specific risk factors, such as menopause, parity and multiparity. The aim of our study was to investigate the association of compartment defects in anorectal and pelvic floor dysfunction with female outlet obstruction constipation (OOC) by MR defecography. Fifty-six consecutive women diagnosed with outlet obstruction constipation from October 2009 to July 2011 were included. They were categorized into the following groups: anorectal disorder only group (27 patients) and anorectal disorder plus multi-compartment pelvic disorder group (29 patients). Relevant measurements were taken at rest, during squeezing and straining. Anismus was significantly more common in the anorectal disorder group compared to the multi-compartment pelvic disorder group. Conversely, rectocele, rectal prolapse, and descending perineum were significantly more common in the multi-compartment pelvic disorder group compared to the anorectal disorder group. Of the total 56 OOC patients, 34 (60.7%) exhibited anismus and 38 (67.9%) rectocele. Among the anismus patients, there were 8 patients (23.5%) with combined cystocele, and 6 patients (17.6%) with combined vaginal/cervical prolapse. Among the rectocele patients, there were 23 patients (60.5%) with combined cystocele and 18 patients (47.4%) with combined vaginal/cervical prolapse. With respect to anorectal defects, 13 anismus patients (38.2%) were with signal posterior pelvic defects, 4 rectocele patients (10.5%) presented with signal posterior pelvic defects. Inadequate defecatory propulsion due to outlet obstruction constipation is often associated with multi-compartment pelvic floor disorders, whereas not about dyssynergic defecation.

Small upper airway measurements areas and high body mass index are recognized risk factors for obstructive sleep apnea syndrome (OSAS) in non-elderly populations; however, there is limited information regarding elderly patients. We evaluated whether upper airway volume is associated with OSAS and OSAS treated with continuous positive airway pressure (CPAP) treatment and whether BMI is correlated with upper airway volume and measurements in elderly subjects. In 60 volunteers aged 75.58±0.9 years: 20 OSAS, 20 OSAS chronically treated with CPAP, and 20 controls, semi-automatic segmentation, retropalatal distance and transverse diameter of the supra-epiglottic upper airway were evaluated using 3DT1-weighted magnetic resonance imaging. Anteroposterior to transverse diameter ratio was defined as retropalatar diameter/transverse diameter. There were no significant differences in supra-epiglottic upper airway volume between OSAS, CPAP treated patients, and controls. There were significant differences in retropalatal distance and anteroposterior to transverse diameter ratio between OSAS, CPAP treated patients, and controls (P = 0.008 and Psupra-epiglottic upper airway volume. In elderly subjects, OSAS and body mass index are not associated with changes in supra-epiglottic upper airway volume but are associated with modification of pharynx shape.

Full Text Available Patients with obstructive sleep apnea syndrome (OSAS may have impaired neuropsychological performance. The aim of the study is to assess neuropsychological function in OSAS patients before and on continous positive airway pressure (CPAP therapy to assess different neuropsychological tests – especially of sensomotor memory – in OSAS patients, and to relate neuropsychological test results to polysomnographic findings. Therefore, 36 normal controls and 18 OSAS patients performed tests of attention capacity and memory with retrieval in the evening and the following morning. Six weeks later, the tests were repeated (patients on CPAP. Controls performed significantly better than patients in the tests of attention and of memory of facts without and on CPAP therapy. Moreover, good compliance of CPAP therapy was not associated with better performance. However, there was no significant difference between controls and patients in the tests of sensomotor memory. The neuropsychological results depended on oxygen values, the arousal index, and sleep stages. There is no group difference in overnight improvement in the neuropsychological tests, which could indicate that sleep has an important function in homeostatic regulation rather than in consolidation.

Full Text Available The aim of research was to estimate the influence of hormone metabolism and sleep apnea on patients with obesity. 76 patients (37 males and 39 females with obesity were included in this study. After night polysomnography all patients were divided in two groups comparableby age, sex ratio and BMI. The first group consisted of 41 patients with obstructive sleep apnea syndrome (OSAS, the second (controls – 35 patients without breath disorders during sleep. OSAS is accompanied by the increase in urinary cortisol during the night, high levels ofbasal insulin, disturbances of hepatic production of IGF-1, dysfunction of the pituitary-gonadal axis. Our results show that sleep-related breathing disorders render markedly and negatively affect on hormonal parameters of patients with obesity. As a reliable difference of basalsecretion of orexin A in obese patients with and without OSAS was not revealed (42,0 [14; 99,5] vs. 18,0 [14,5; 124,5] pg/ml; р=0,9, we were not able to show the existence that the existence of OSAS is followed by any special changes of activity of the orexin system.

Stress cardiomyopathy (SC) syndrome represents a reversible form of cardiomyopathy that commonly presents proximate to an acute emotional or physiologic stressor. The clinical presentation is similar to an acute coronary syndrome in the absence of obstructive coronary artery disease to explain the unusual distribution of associated transient wall motion abnormalities. Postmenopausal women seem particularly prone to SC for unclear reasons. The pathophysiology of the syndrome is unknown but may involve pathologic sympathetic myocardial stimulation.

Anismus causes obstructed defecation as a result of inappropriate contraction of the puborectalis/external sphincter. Proctographic failure to empty after 30 s is used as a simple surrogate for simultaneous electromyography/proctography. Botulinum toxin is theoretically attractive but efficacy is variable. We aimed to evaluate the efficacy of botulinum toxin to treat obstructed defecation caused by anismus. Botulinum toxin was administered, under local anaesthetic, into the puborectalis/external sphincter of patients with proctographic anismus. Responders (resolution followed by recurrence of obstructed defecation over a 1- to 2-month period) underwent repeat injection. Nonresponders underwent rectal examination under anaesthetic (EUA). EUA-diagnosed rectal prolapse was graded using the Oxford Prolapse Grade 1-5. Fifty-six patients were treated with botulinum toxin. Twenty-two (39%) responded initially and 21/22 (95%) underwent repeat treatment. At a median follow up of 19.2 (range, 7.0-30.4) months, 20/21 (95%) had a sustained response and required no further treatment. Isolated obstructed defecation symptoms (OR = 7.8, P = 0.008), but not proctographic or physiological factors, predicted response on logistic regression analysis. In 33 (97%) of 34 nonresponders, significant abnormalities were demonstrated at EUA: 31 (94%) had a grade 3-5 rectal prolapse, one had internal anal sphincter myopathy and one had a fissure. Exclusion of these alternative diagnoses revised the initial response rate to 96%. Simple proctographic criteria overdiagnose anismus and underdiagnose rectal prolapse. This explains the published variable response to botulinum toxin. Failure to respond should prompt EUA seeking undiagnosed rectal prolapse. A response to an initial dose of botulinum toxin might be considered a more reliable diagnosis of anismus than proctography. © 2011 The Authors.

Full Text Available Herlyn-Werner-Wunderlich (HWW syndrome is an uncommon combined müllerian duct anomalies (MDAs and mesonephric duct malformation of female urogenital tract characterized by uterus didelphys and obstructed hemi-vagina and ipsilateral renal agenesis (OHVIRA syndrome. We present a rare and unusual case of this syndrome in a 19 year-old female who suffered from hypomenorrhoea and abdominal pain. She had an obstructed hemi-vagina on right side which led to marked distention of ipsilateral cervix, while proximal hemi-vagina compressed the contralateral side causing its partial obstruction resulting in hypomenorrhoea. Understanding the imaging findings of this rare condition is important for early diagnosis in order to prevent complications which may lead to infertility.

Anismus: the cause of constipation? Results of investigation and treatment.

Anismus, or failure of the somatic sphincter apparatus to relax at defecation, has been implicated as a major contributor to the problem of obstructed defecation. Current diagnostic methods depend on laboratory measurements of attempted defecation and the most complex, dynamic proctography has been the mainstay of diagnosis. Using a new computerized ambulatory method of recording sphincter function in these patients at home, we report an 80% reduction in our diagnostic rate suggesting that conventional tests fail to accurately diagnose this condition, probably because they poorly represent the natural physiology of defecation. Treatment of this distressing condition is more complex and a variety of surgical and pharmacological measures have failed. Biofeedback retraining of anorectal function of these patients has been very successful and represents the management of choice.

Objective: To investigate the correlation of soft tissue structure of upper airway with the pathogenesis of obstructive sleep apnea syndrome (OSAS) in adolescents age group by analyzing magnetic resonance imaging (MRI) of upper airway. Methods: The subjects were divided into obese OSAS, obese controls and normal weight controls groups according to the results from polysomnography and body mass index measurements; Upper airway was scanned by MRI sagittally and axially; upper airway at all levels and soft tissue was analyzed by Amira Medical image analysis system. Results: Tongue volumes in obese OSAS and obese controls were significantly greater than that in normal weight controls (P<0.05); tonsil and adenoid volumes in obese OSAS were significantly higher than those in two control groups (P<0.05 or P<0.001), but no significant difference was found between two control groups. The volumes of lateral pharyngeal wall in obese OSAS were higher than those in obese controls and normal weight controls (P<0.05 or P<0.001), and they were higher in obese controls compared with normal weight controls (P<0.05). In obese OSAS group, positive correlations were found between volumes of lateral pharyngeal wall and apnea/hypopnea index (AHI) (r=0.879, P<0.01), as well volumes of tonsils and AHI (r=0.824, P<0.01). Conclusion: Obesity can increase the soft tissue volumes around upper airway, there by increase the upper airway obstruction; lateral pharyngeal wall and adenoid volumes play major roles in evaluating the severity of OSAS in adolescents.

Objective: To investigate the clinical value of multivoxel 1 H magnetic resonance spectroscopy ( 1 H-MRS) in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Materials and Methods: 20 patients (case group) with moderate to severe clinically diagnosed OSAHS and 20 age-gender matched healthy volunteers (control group) underwent brain multivoxel 1 H-MRS examinations. The ratios of brain metabolites of centrum ovale and basal ganglia were recorded respectively. Related clinical indexes, including sleep apnea and hypopnea index (AHI) and the average night-time oxygen saturation (SpO 2 ), were recorded. Results: In region of centrum ovale, the NAA/Cho and NAA/Cr of the case group decreased and were significantly lower than that of control group (P<0.05). The Cho/Cr of the case group was significantly increased compared to the controls (P<0.05). In region of basal ganglia, the NAA/Cho, NAA/Cr, and Cho/Cr had no significantly difference between the two groups (P>0.05). Lactate peak was not detected in the two groups. In the region of centrum ovale, the AHI showed inverse correlation to the NAA/Cho (P<0.05). The SpO 2 showed positive correlations to the NAA/Cho (P<0.05). There was no correlation between clinical indexes and NAA/Cr or Cho/Cr (P>0.05). Conclusion: Multivoxel 1 H-MRS could early detect the changes of cerebral metabolism in patients with OSAHS. It provides an objective imaging basis for the clinical diagnosis and treatment. (authors)

Obstructive sleep apnea (OSA) is a common respiratory disorder associated with hypertension and cardiovascular complications. Blood pressure variability may be a sign of risk of cardiovascular events. The aim of this study was to investigate the hypothesis that severe OSA syndrome is associated with increased blood pressure variability. Based on respiratory polygraphy, 58 patients were categorized into two groups: severe OSA with apnea/hypopnea index (AHI) greater than 29 episodes per hour (mean 52.2 ± 19.0/h) and mild-to-moderate OSA with AHI between 5 and 30 episodes per hour (mean 20.2 ± 7.8/h). A 24-h noninvasive blood pressure monitoring was performed. The standard deviation of mean blood pressure was used as the indicator of blood pressure variability. In patients with severe, compared with mild-to-moderate OSA, a higher mean nocturnal systolic blood pressure (133.2 ± 17.4 mmHg vs. 117.7 ± 31.2 mmHg, p variability (12.1 ± 6.0 vs. 7.6 ± 4.3, p variability (10.5 ± 6.1 vs. 7.3 ± 4.0 p variability (9.1 ± 4.9 mmHg vs. 6.8 ± 3.5 mmHg) were detected. The findings of the study point to increased nocturnal systolic and diastolic arterial blood pressure and blood pressure variability as risk factors of cardiovascular complications in patients with severe OSA.

Ectrodactyly-ectodermal dysplasia and clefting syndrome or "Lobster claw" deformity is a rare congenital anomaly that affects tissues of ectodermal and mesodermal origin. Nasolacrimal duct (NLD) obstruction with or without atresia of lacrimal passage is a common finding of such a syndrome. The authors report here even a rarer presentation of the syndrome which manifested as bilateral NLD obstruction and lacrimal fistula along with cleft lip and palate, syndactyly affecting all four limbs, mild mental retardation, otitis media, and sinusitis. Lacrimal duct obstruction and fistula were managed successfully with endoscopic dacryocystorhinostomy (DCR) which is a good alternative to lacrimal probing or open DCR in such a case.

To evaluate the results and clinical impact of defecography in patients with anorectal diseases, 304 defecographic examinations from 304 patients were reviewed. The defecographic results were screened for the anorectal angle and perineal descent at rest, squeezing and during straining. Changes of rectal configuration and canal width during straining were reviewed. 304 patients had defecation problems such as terminal constipation, defecation difficulty, blood or mucus discharge, tenesmus, obstruction sensation etc.. They were performed anorectal physical examination and anal manometry etc., and were later treated by operation and conservative management. Normal anorectal angle were measured to be 101 .deg., 91 .deg., 131 .deg. at rest, during squeezing and straining respectively. In the spastic pelvic floor syndrome, increase of anorectal angle less than 10 degrees from rest to straining was observed. Incontinent patients had a larger anorectal angle (mean: 128 .deg.) at rest. 7.8cm of perineal descent was found in descending perineal syndrome in comparison to 4.0cm in normal. Normal anal canal width was measured 1.4cm only during straining, but identified in incontinent patients at rest (mean: 1.2cm). Abnormal rectal configuration was found in 254 defecographic examinations: rectoceles were observed in 235 cases and were associated with rectal prolapse in 115 cases, and rectal prolapses were found in 134 cases. In conclusion, the anorectal angle was valuable in evaluation of spastic pelvic floor syndrome and fecal incontinence. Degree of perineal descent was abnormally increased in descending perineal syndrome. In the cases of the rectoceles and rectal prolapses, defecography is helpful in preoperative evaluation of rectal wall change and postoperative follow up

The burden of chronic obstructive pulmonary disease (COPD) is increasing, yet there are limited data on early life risk factors. To investigate the role of childhood lung function in adult COPD phenotypes. Prebronchodilator spirometry was performed for a cohort of 7-year-old Tasmanian children (n = 8,583) in 1968 who were resurveyed at 45 years, and a selected subsample (n = 1,389) underwent prebronchodilator and post-bronchodilator spirometry. For this analysis, COPD was spirometrically defined as a post-bronchodilator FEV 1 /FVC less than the lower limit of normal. Asthma-COPD overlap syndrome (ACOS) was defined as the coexistence of both COPD and current asthma. Associations between childhood lung function and asthma/COPD/ACOS were examined using multinomial regression. At 45 years, 959 participants had neither current asthma nor COPD (unaffected), 269 had current asthma alone, 59 had COPD alone, and 68 had ACOS. The reweighted prevalence of asthma alone was 13.5%, COPD alone 4.1%, and ACOS 2.9%. The lowest quartile of FEV 1 at 7 years was associated with ACOS (odds ratio, 2.93; 95% confidence interval, 1.32-6.52), but not COPD or asthma alone. The lowest quartile of FEV 1 /FVC ratio at 7 years was associated with ACOS (odds ratio, 16.3; 95% confidence interval, 4.7-55.9) and COPD (odds ratio, 5.76; 95% confidence interval, 1.9-17.4), but not asthma alone. Being in the lowest quartile for lung function at age 7 may have long-term consequences for the development of COPD and ACOS by middle age. Screening of lung function in school age children may identify a high-risk group that could be targeted for intervention. Further research is needed to understand possible modifiers of these associations and develop interventions for children with impaired lung function.

Full Text Available A associação entre SAOS e a síndrome metabólica é reconhecida, sendo denominada síndrome Z. Os critérios para a síndrome metabólica incluem pelo menos três dos seguintes fatores: obesidade central (circunferência da cintura > 102 cm em homens e > 88 cm em mulheres; triglicérides > 150 mg/dL; HDL colesterol 130/85 mmHg; e glicemia de jejum > 100 mg/dL. A obesidade central esta associada a SAOS e síndrome metabólica, havendo evidências de que a apneia do sono seja um fator de risco independente da obesidade, intolerância à glicose e resistência insulínica. Embora a obesidade central seja um fator de risco para ambas as condições, há evidências de que a apneia do sono seja um fator de risco independente para a intolerância à glicose e a resistência à insulina. Os mecanismos implicados decorrem da ativação do sistema nervoso simpático e do eixo hipotálamo-hipófise-adrenal; da ativação de fatores pró-inflamatórios, como IL-6 e TNF-α; e da diminuição dos níveis de adiponectina mediados principalmente pela hipoxemia intermitente relacionada às apneias. Apesar dessas evidências, os resultados dos estudos são controversos em relação aos benefícios do tratamento da apneia do sono com CPAP nas alterações metabólicas. Adicionalmente, os poucos estudos que abordaram a apneia do sono obstrutiva como um fator de risco para as dislipidemias apresentaram resultados discordantes. Estudos controlados, populacionais e longitudinais são necessários para esclarecer a interação entre a apneia do sono e as consequências metabólicas no sentido de se tratar adequadamente esses indivíduos.There is a recognized association between obstructive sleep apnea syndrome and metabolic syndrome, designated syndrome Z.

Obstructive sleep apnea and hypopnea syndrome (OSAHS) is one of the developmental factors of high blood pressure (HBP), a relevant global public health problem. OSAHS is characterized by the reduction or complete cessation of respiratory airflow due to intermittent airway collapse. Additionally, significant changes in sleep rhythm and pattern are observed in these patients. To evaluate the association between OSAHS and sleep quality in essential and resistant hypertensives. A cross-sectional, observational study evaluated 43 hypertensive patients treated at the outpatient clinics of the Faculdade de Medicina do ABC (FMABC) who were medicated with two or more antihypertensive drugs and divided into nonresistant or resistant to treatment. Group I (using up to two antihypertensive agents - 60.47% of the sample) presented mean systolic blood pressure (SBP) of 127.5±6.4 mmHg, mean diastolic blood pressure (DBP) of 79.6±5.2 mmHg, mean body mass index (BMI) of 27.2±5.3 kg/m2 and mean age of 51.2±15.1 years. Group II (using more than two antihypertensive drugs - 37.2% of the sample) presented mean SBP of 132.1±9.3 mmHg, mean DBP of 84.5±5.8 mmHg, mean BMI of 27.2±7.2 kg/m2 and mean age of 55.5±13.4 years. The patients presented low quality of sleep/sleep disorder evaluated by the Pittsburgh Sleep Quality Index (PSQI), which represents a preponderant factor for OSAHS. Patients at high risk for OSAHS had poor sleep quality and high levels of DBP, suggesting a causal relation between these parameters. However, they did not present a higher prevalence of resistant high blood pressure (RHBP).

New treatments for relapse of acute myeloid leukaemia (AML), include gemtuzumab ozogamicin (GO), an anti-CD33 monoclonal antibody. We describe a second case of GO-induced sinusoidal obstructive syndrome (SOS) effectively treated with defibrotide (DF). No stem-cell transplantation was involved. On day 23 after the first GO dose, a patient presented with ascites, weight gain, liver enlargement and pain in the right upper quadrant. Sudden hepatic cytolysis (transaminases at six times the normal range: grade 3) and cholestasis [alkaline phosphatase ALP and gamma-glutamyltransferase (GGT) respectively at four and eight times the normal range: grade 2] were observed but there was no evidence of increase serum bilirubin. Treatment with DF (Prociclide), Crinos; 10 mg/kg/day, or 200 mg, q.i.d.) improved the hepatic abnormality within a few days (serum transaminases decreased from 312 to 103 IU/L for aspartate aminotransferase (AST) and from 141 to 80 IU/L for alanine aminotransferase (ALT) within 3 days ALP increased from 253 to 383 IU/L and gamma-GT from 238 to 417 IU/L 4 days after administration of DF. The clinical and biological features of our case suggest a direct involvement of GO in causing SOS, even when used as monotherapy, without allogenic stem-cell transplantation. Low dose DF (10 mg/kg/day) given early during the development of SOS associated with GO was effective. Unfortunately, in our case the patient eventually died of multi-organ failure probably because of failure of GO.

Severe bronchial obstruction due to one of the major pulmonary diseases: asthma, COPD, or emphysema often requires mechanical ventilation support. Otherwise, patients are at risk of severe hypooxygenation with consecutive overloading and dilatation of the right cardiac ventricle with subsequent failure. This review focuses on how to manage a calculated ventilation therapy of patients suffering from bronchial obstruction and relevant patents. Options and pitfalls of invasive and non-invasive ventilation in the intensive care setting regarding clinical improvement and final outcome are discussed. The non-invasive ventilation is very efficient in treating acute or chronic respiratory failure in COPD patients and is capable of shortening the duration of hospitalization. Further non-invasive ventilation can successfully support the weaning after a long-lasting ventilation therapy and improve the prognosis of COPD patients. "Permissive hypercapnia" is unequivocally established in invasive ventilation therapy of severe bronchial obstruction in situations of limited ventilation. When intrinsic positive end-expiratory pressure (PEEP) and elevated airways resistance are present PEEP may be useful although external-PEEP application relieves over-inflation only in selected patients with airway obstruction during controlled mechanical ventilation. Upper limit of airways peak pressure used in "protective ventilation" of adult respiratory distress syndrome (ARDS) patients can be exceeded under certain circumstances.

Background Research suggests that the lived experience of inadequate sanitation may contribute to poor health outcomes above and beyond pathogen exposure, particularly among women. The goal of this research was to understand women’s lived experiences of sanitation by documenting their urination-related, defecation-related and menstruation-related concerns, to use findings to develop a definition of sanitation insecurity among women in low-income settings and to develop a conceptual model to explain the factors that contribute to their experiences, including potential behavioural and health consequences. Methods We conducted 69 Free-List Interviews and eight focus group discussions in a rural population in Odisha, India to identify women’s sanitation concerns and to build an understanding of sanitation insecurity. Findings We found that women at different life stages in rural Odisha, India have a multitude of unaddressed urination, defecation and menstruation concerns. Concerns fell into four domains: the sociocultural context, the physical environment, the social environment and personal constraints. These varied by season, time of day, life stage and toilet ownership, and were linked with an array of adaptations (ie, suppression, withholding food and water) and consequences (ie, scolding, shame, fear). Our derived definition and conceptual model of sanitation insecurity reflect these four domains. Discussion To sincerely address women’s sanitation needs, our findings indicate that more is needed than facilities that change the physical environment alone. Efforts to enable urinating, defecating and managing menstruation independently, comfortably, safely, hygienically, privately, healthily, with dignity and as needed require transformative approaches that also address the gendered, sociocultural and social environments that impact women despite facility access. This research lays the groundwork for future sanitation studies to validate or refine the proposed

More than 1 billion people are currently infected with soil-transmitted helminths and schistosomes. The global strategy to control helminthiases is the regular administration of anthelmintic drugs to at-risk populations. However, rapid re-infection occurs in areas where hygiene, access to clean water, and sanitation are inadequate. In July 2011, inhabitants from two villages and seven hamlets of the Taabo health demographic surveillance system in south-central Côte d'Ivoire provided stool and urine samples. Kato-Katz and ether-concentration methods were used for the diagnosis of Schistosoma mansoni, soil-transmitted helminths (Ascaris lumbricoides, Trichuris trichiura, and hookworm), and intestinal protozoa. Urine samples were subjected to a filtration method for the diagnosis of Schistosoma haematobium. A questionnaire was administered to households to obtain information on knowledge, attitude, practice, and beliefs in relation to hygiene, sanitation, and defecation behavior. Logistic regression models were employed to assess for associations between questionnaire data and parasitic infections. A total of 1,894 participants had complete data records. Parasitological examinations revealed prevalences of hookworm, S. haematobium, T. trichiura, S. mansoni, and A. lumbricoides of 33.5%, 7.0%, 1.6%, 1.3% and 0.8%, respectively. Giardia intestinalis and Entamoeba histolytica/E. dispar were detected in 15.0% and 14.4% of the participants, respectively. Only one out of five households reported the presence of a latrine, and hence, open defecation was common. Logistic regression analysis revealed that age, sex, socioeconomic status, hygiene, and defecation behavior are determinants for helminths and intestinal protozoa infections. We found that inadequate sanitation and hygiene behavior are associated with soil-transmitted helminths and intestinal protozoa infections in the Taabo area of south-central Côte d'Ivoire. Our data will serve as a benchmark to monitor the

To determine of pattern analysis of defecography can predict the responsiveness of biofeedback therapy in patients with chronic functional constipation. Over a two-year period, 104 patients with chronic functional constipation underwent defecography and biofeedback therapy. Two blinded readers analyzed the defecographic findings and classified them into six types; I = normal defecation, II = hypertonic lower anal sphincter (poor anal opening due to a persistent contraction of the lower anal sphincter), III dyskinetic puborectal sling (inadequate laxity of the puborectal sling), IV spastic pelvic floor syndrome (persistent contraction of both the puborectal sling and the lower and sphincter), V unclassified (including paradoxical contraction of the anal sphincter), VI anatomical obstruction. In addition, the degree of rectal contraction during defecation was scored (grade 0 to 3). After biofeedback therapy, the differences in the defecography patterns or rectal contraction between the two groups, the responsive or non-responsive group, were analyzed. The defecograms revealed that the type IV of the spastic pelvic floor syndrome was most common (50 of 104 patients, 48%), followed by II (21/104, 20%), III (12/104, 11.5%), V (9/104, 9%) and VI (12/104, 11.5%). Biofeedback therapy showed a therapeutic response in 71 out of 104 patients (68%) but failed in 33 patients (32%). However, there were no significant differences in the defecographic pattern between the responsive and non-responsive groups ({rho} = 0.630). The defecograms revealed contractions in 78 patients (75%) and moderate to vigorous contractions (more than grade 2) in 66 patients. Most of the biofeedback-responsive group showed rectal contractions (66 of 71 patients, 93%, {rho} < 0.001). In patients with chronic functional constipation, there was no significant difference in the morphological patterns of the defecogram between the responsive and non-responsive biofeedback groups.

The hot spot on liver scan was demonstrated by many authors in various conditions such as SVC obstruction, Budd-Chiari syndrome, liver abscess, hemangioma of liver, hepatic venoocclusive diseases, IVC obstruction, and tricuspid insufficiency. And the appearance of hot spot in SVC obstruction is due to unusual collateral circulation. But there was no report of this hots pot on liver scan in our country. We have recently observed one patient with SVC obstruction who shows well-defined area of increased radioactivity between right and left lobe of liver on liver scan using {sup 99m}Tc-tin colloid, and demonstrated collateral circulations with RI venography using {sup 99m}Tc-O{sub 4}. The injection site of radiocolloid was left antecubital vein. This hot spot did not appear when the radiocolloid was injected into right leg vein. We report here this hoe spot on liver scan in SVC obstruction with review of some literatures.

The overlap syndrome of asthma and COPD: what are its features and how important is it?

There is a need to re-evaluate the concept of asthma and chronic obstructive pulmonary disease (COPD) as separate conditions, and to consider situations when they may coexist, or when one condition may evolve into the other. Epidemiological studies show that in older people with obstructive airway disease, as many as half or more may have overlapping diagnoses of asthma and COPD (overlap syndrome). These people are typically excluded from current therapy trials, which limit the generalisability of these trials, and this presents a problem for evidence-based guidelines for obstructive airway diseases. Studying overlap syndrome may shed light on the mechanisms of COPD development. Overlap syndrome is recognised by the coexistence of increased variability of airflow in a patient with incompletely reversible airway obstruction. Patients typically have inflammatory features that resemble COPD, with increased airway neutrophilia, as well as features of airway wall remodelling. Overlap syndrome can develop when there is accelerated decline in lung function, or incomplete lung growth, or both. The risk factors for these events are shared, such that increasing age, bronchial hyper-responsiveness, tobacco smoke exposure, asthma and lower respiratory infections/exacerbations are significant risk factors for both incomplete lung growth and accelerated loss of lung function. Studying these events may offer new insights into the mechanisms and treatment of obstructive airway diseases.

Background: Little is known about the association of race-ethnicity and the relationship of continuous positive airway pressure (CPAP) adherence with functional outcomes of sleep in American samples with obstructive sleep apnea syndrome (OSAS). This retrospective study examines whether race-ethnicity moderates the relationship between CPAP adherence and functional outcomes of sleep in OSAS. Methods: Over 4 months, consecutive OSAS patients had CPAP data downloads and completed questionnaires (demographics, Functional Outcomes of Sleep Questionnaire [FOSQ], Epworth Sleepiness Scale [ESS], Insomnia Severity Index [ISI]) at the Miami VA sleep center. Medical diagnoses and polysomnography data were obtained from medical record. CPAP adherence was measured as mean daily hours of use. Hierarchical regression modeling was used to explore the differential impact of race-ethnicity and CPAP adherence on functional outcomes of sleep. Results: Two hundred twenty-seven veterans (93% male, age 59 ± 11 years) were included; 142 (63%) participants self-reported as white or Hispanic, and 85 participants (37%) as black. Hierarchical regression analyses failed to show main effects for race-ethnicity or CPAP use and FOSQ scores; however, the interaction of race-ethnicity with CPAP adherence was significantly associated with the total FOSQ (p = 0.04), Social (p = 0.02), and Intimacy (p = 0.01) subscale scores. For blacks, in adjusted analyses, CPAP adherence was positively associated with Social and Intimacy FOSQ subscales; however, no significant relationship was noted between CPAP use and FOSQ scores in whites/Hispanics. Conclusions: Race-ethnicity may moderate the relationship between CPAP adherence and some functional outcomes of sleep; however, further studies are needed. Citation: Wallace DM, Wohlgemuth WK.

The main curative treatment of colorectal cancer remains the surgery. However, when metastases are suspected, surgery is followed by a preventive chemotherapy using oxaliplatin which, unfortunately, may cause liver sinusoidal obstruction syndrome (SOS). Such hepatic damage is barely detected during or after chemotherapy due to a lack of effective diagnostic procedures, but liver biopsy. The primary objective of the present study was to identify potential early diagnosis biomarkers of SOS using a metabonomic approach. SOS was induced in rats by monocrotaline, a prototypical toxic substance. 1 H NMR spectroscopy analysis of urine samples collected from rats treated with monocrotaline showed significant metabolic changes as compared to controls. During a first phase, cellular protective mechanisms such as an increased synthesis of GSH (reduced taurine) and the recruitment of cell osmolytes in the liver (betaine) were seen. In the second phase, the disturbance of the urea cycle (increased ornithine and urea reduction) leading to the depletion of NO, the alteration in the GSH synthesis (increased creatine and GSH precursors (glutamate, dimethylglycine and sarcosine)), and the liver necrosis (decrease taurine and increase creatine) all indicate the development of SOS. - Highlights: • Urine metabonomic profiles of SOS have been identified. • Urine osmoprotectants and anti-oxidants indicated an initial liver protection. • Liver necrosis was demonstrated by increased urine levels of taurine and creatine. • NO depletion was suggested by changes in ornithine and urea

Sinusoidal obstructive syndrome (SOS) is a potentially fatal form of hepatic injury after hematopoietic stem cell transplantation. Patients can develop liver dysfunction, portal hypertension, ascites, coagulopathies, and multisystem organ failure. The mortality rate of severe SOS has been reported as high as 98% by day 100 after transplantation. Defibrotide, which is now approved for the treatment of SOS, has significantly decreased mortality. Defibrotide is a polynucleotide with profibrinolytic, anti-ischemic, and anti-inflammatory activity. These properties can increase the risk of life-threatening bleeding in this patient population. Previous protocols have suggested maintaining international normalized ratio ≤ 1.5, platelets > 30 k/uL, and fibrinogen ≥ 150 mg/dL to minimize this risk of bleeding. However, this can be challenging in fluid-sensitive patients with SOS. Thromboelastography (TEG) is a functional assay that evaluates the balance of procoagulant and anticoagulant proteins. In this series, TEG was used to guide defibrotide therapy as well as blood product transfusions in SOS patients with abnormal coagulation studies. Each patient recovered from SOS and had no bleeding complications. A randomized clinical trial is the next step in supporting the use of TEG in SOS patients with abnormal coagulation studies receiving defibrotide therapy.

Thanks to modern multimodal treatment the ouctome of patients with colorectal cancer has experienced significant improvements. As a downside, agent specific side effects have been observed such as sinusoidal obstruction syndrome (SOS) after oxaliplatin chemotherapy (OX). Bevazicumab targeting VEGF is nowadays comprehensively used in combination protocols with OX but its impact on hepatotoxicity is thus far elusive and focus of the present study. After MCT administration 67% of animals developed SOS. GOT serum concentration significantly increased in animals developing SOS ( p SOS. In contrast, animals receiving VEGF developed SOS merely in 40% while increasing the VEGF dose led to a further decrease in SOS development to 25%. MMP 9 concentration in animals developing SOS was significantly higher compared to controls ( p SOS paralleled by MMP 9 production. Therefore, OX-Bevacizumab combination therapies should be administered with caution, especially if liver parenchyma damage is apparent. Male Sprague-Dawley rats were gavaged Monocrotaline (MCT) to induce SOS. Recombinant VEGF or an Anti-VEGF antibody was administered to MCT-treated rats and the hepatotoxic effect monitored in defined time intervals. MMP 9 expression in the liver was measured by ELISA.

Hepatic sinusoidal obstruction syndrome (HSOS) can be caused by pyrrolizidine alkaloids(PAs)-containing herbals. Since PAs exposure is obscure and clinical presentation of HSOS is unspecific, it is challenge to establish the diagnosis of PAs-induced HSOS. Gynura segetum is one of the most wide-use herbals containing PAs. The aim of our study is to describe the features of contrast-enhanced computed tomography (CT) in gynura segetum-induced HSOS, and then determine diagnostic performance of radiological signs. We retrospectively analyzed medical records and CT images of HSOS patients (71 cases) and the controls (222 cases) enrolled from January 1, 2008, to Oct 31, 2015. The common findings of contrast CT in PAs-induced HSOS included: ascites (100%), hepatomegaly (78.87%), gallbladder wall thickening (86.96%), pleural effusion (70.42%), hepatic vein narrowing (87.32%), patchy liver enhancement (92.96%), and heterogeneous hypoattenuation (100%); of these signs, patchy enhancement and heterogeneous hypoattenuation were valuable features. Then, the result of diagnostic performance demonstrated that contrast CT possessed better performance in diagnosing PAs-induced HSOS compared with various parameters of Seattle criteria. In conclusion, the patients with PAs-induced HSOS display distinct radiologic features at CT-scan, which reveals that contrast-enhanced CT provides an effective noninvasive method for diagnosing PAs-induced HSOS.

Background Poor sanitation is thought to be a major cause of enteric infections among young children. However, there are no previously published randomized trials to measure the health impacts of large-scale sanitation programs. India's Total Sanitation Campaign (TSC) is one such program that seeks to end the practice of open defecation by changing social norms and behaviors, and providing technical support and financial subsidies. The objective of this study was to measure the effect of the TSC implemented with capacity building support from the World Bank's Water and Sanitation Program in Madhya Pradesh on availability of individual household latrines (IHLs), defecation behaviors, and child health (diarrhea, highly credible gastrointestinal illness [HCGI], parasitic infections, anemia, growth). Methods and Findings We conducted a cluster-randomized, controlled trial in 80 rural villages. Field staff collected baseline measures of sanitation conditions, behaviors, and child health (May–July 2009), and revisited households 21 months later (February–April 2011) after the program was delivered. The study enrolled a random sample of 5,209 children <5 years old from 3,039 households that had at least one child <24 months at the beginning of the study. A random subsample of 1,150 children <24 months at enrollment were tested for soil transmitted helminth and protozoan infections in stool. The randomization successfully balanced intervention and control groups, and we estimated differences between groups in an intention to treat analysis. The intervention increased percentage of households in a village with improved sanitation facilities as defined by the WHO/UNICEF Joint Monitoring Programme by an average of 19% (95% CI for difference: 12%–26%; group means: 22% control versus 41% intervention), decreased open defecation among adults by an average of 10% (95% CI for difference: 4%–15%; group means: 73% intervention versus 84% control).

Obstructive sleep apnea syndrome (OSA) and periodic limb movement in sleep syndrome (PLMS) are two common sleep disorders. Previous studies showed that OSA and PLMS share common features, such as increased cardio-vascular risk, both apnea events and limb movements occur periodically, they are usually associated with cortical arousals, and both of them can induce declines in peripheral oxygen saturation measured with pulse oximetry. However, the question whether apnea events and limb movements also show similar characteristics in cerebral hemodynamic and oxygenation has never been addressed. In this pilot study, we will first time compare the cerebral hemodynamic changes induced by apnea events and limb movements in patients with OSA (n=4) and PLMS (n=4) with NIRS. In patients with OSA, we found periodic oscillations in HbO2, HHb, and blood volume induced by apnea/hypopnea events, HbO2 and HHb showed reverse changing trends. By contrast, the periodic oscillations linked to limb movements were only found in HbO2 and blood volume in patients with PLMS. These findings of different cerebral hemodynamics patterns between apnea events and limb movements may indicate different regulations of nervous system between these two sleep disorders.

One of the causes of open defecation (OD) is low awareness of local community towards open defecation free behavior. This community does not have a healthy toilet and usually defecate in the river. This poor environment is coupled with poverty and small footprint. Therefore, the tr.iggering methods should be modified by including the finance concept in form of stimulant funds to accelerate ODF targets by using appropriate technology for land limitations. The construction of healthy toilet in Kelurahan Kebonsari, Jambangan sub-district, was conducted in RW2 which consisted of RT 6 (4 units) and RT 7 (1 unit) and 2 units in RT 2 of RW 3. Construction was initiated with focus group discussion and indepth interview to locate the proper location to be triggered. Healthy toilet construction was conducted in cooperation among self-help community, Institut Teknologi Sepuluh Nopember (ITS), and the community itself. Every month the users had to pay the toilet construction (capacity of 0.75 m3) of IDR 100,000 for 10 months. Therefore, with this healthy toilet construction, KelurahanKebonsari becomes one of ODF village in Surabaya City.

BACKROUND/AIM: Anismus is paradoxal pressure increase or pressure decrease less than 20% of external anal sphincter during defecation straining. This study analyzed the presence of anismus as within a group of patients with the positive Rome III criteria for functional constipation. We used anorectal manometry as the determination method for anismus. We used anorectal water-perfused manometry in 60 patients with obstructive defecation defined by the Rome III criteria for functional constipation. We also analyzed anorectal function in 30 healthy subjects. The presence of anismus is more frequent in the group of patients with obstructive defecation compared to the control group (a highly statistically significant difference, p anismus with the presence of weak external anal sphincter, rectal sensibility disorders, enlarged piles, diverticular disease and anatomic variations of colon. We found no correlation between them in any of these cases. There is a significant correlation between anismus and positive Rome III criteria for functional constipation. Anorectal manometry should be performed in all patients with the positive Rome III criteria for functional constipation.

Membranous obstruction is the most common cause of Budd-Chiari syndrome in Orientals. Recently, percutaneous transluminal balloon angioplasty (PTBA) has been successfully applied as a treatment of membranous obstruction. We evaluated etiologies and clinical manifestations in our cases and the usefulness of PTBA. Twelve cases of Budd-Chiari syndrome were analyzed. 50.3 years was the average age of the cases (ranging from 37 to 67 years). Major symptoms or signs were superficial collateral vessels on the chest or the abdomen in 6 cases, ascites in 3, abdominal pain in 4, hepatomegaly in 4, splenomegaly in 3, melena or hematemesis in 2, and leg edema in 2. Upper gastrointestinal endoscopy showed esophageal varices in 6 cases and two of these 6 cases had gastric varices. Of 8 cases with liver cirrhosis, 4 were classified as Child-Pugh class A and 4 as B. Four patients with cirrhosis had concurrent hepatocellular carcinoma including 1 patient who was HBs Ag positive. Etiologies were membranous obstruction in 11 cases and protein C deficiency in 1 case. The main site of obstruction was IVC in 8 and hepatic vein in 4. PTBA was successfully performed in 8 cases of membranous obstruction. During the mean follow-up period of 27.6 months (12-40 months), there were no reobstructions except in 2 cases. The most common cause of Budd-Chiari syndrome in our cases was membranous obstruction of IVC. Percutaneous transluminal balloon angioplasty is a very useful treatment method.

She was found to have severe bowel obstruction due to advanced transverse colon cancer on plain computed tomography (CT) and colonoscopy. We performed colonic stenting safely, and the symptom promptly improved. Defecation and flatus were observed on the same day of stenting, and the patient was able to start drinking and eating on the next day. Enhanced abdominal CT revealed multiple liver metastasis, peritoneal dissemination, ascites, and cystic ovarian tumor. After treatment with 1 course of 5-fluorouracil, Leucovorin, and oxaliplatin (mFOLFOX6), the patient was discharged on day 14 after admission. The rapidly enlarging ovarian tumors and primary colonic lesion with SEMS were surgically removed after treatment with mFOLFOX6 for 4 months in an outpatient basis. The patient has been alive with a good quality of life (QOL) and being treated with bevacizumab plus mFOLFOX6/Leucovorin, 5-fluorouracil, and irinotecan( FOLFIRI) for 6 months. SEMS placement could be safe and effective for the treatment of obstruction of the right colon, and could maintain a good QOL in patients.

Full Text Available The diagnosis of constipation is complicated due to the multiplicity and complexity of the causes. Regarding diagnostic tests, proctography is the best choice because it provides information on functions and visualization of abnormalities. Objective: To measure the isolated value of proctography in patients with obstructed defecation. Method: We evaluated 40 constipated patients at the Coloproctology Clinic of Santa Casa de Misericórdia de São Paulo. The test was performed by introducing 120 mL of barium contrast in the rectum and by analyzing the different stages of evacuation. Three x-rays were performed in the lateral position: rest, anal contraction and evacuation. Results: The diagnoses were: rectocele: 2 (5.0%; anismus: 8 (20.0%; perineal descent: 13 (32.5%; sigmoidocele: 6 (15.0%; internal invagination: 10 (25.0%; rectocele + sigmoidocele 9 (22.5%; rectocele + internal invagination 11 (27.5%; rectocele + anismus: 18 (45.0%. Several patients presented multiple disorders. Conclusion: Constipation by obstructed defecation depends on multiple factors and it is important to have an accurate diagnosis. Proctography is essential, but insufficient as a single procedure. The other tests contribute with the diagnosis, therefore, they should be included in the investigation.O diagnóstico da constipação é difícil pela multiplicidade e complexidade das causas.

To investigate the prethrombotic state (PTS) in patients with obstructive sleep apnea syndrome (OS-AS) and the effect of continuous positive airway pressure ventilation (CPAP) on their PTS, the blood samples of 49 patients with OSAS were taken before treatment and on day 30 after treatment respectively. The platelet aggregation ( PAG), P-selections, endothdlin-1 (ET-1) and plasma vom willebrand factor (vWF) in 49 patients and 42 health controls were detected by radioimmunoassay and enzyme-immunoassay. The results showed that the PAG, P-selections, ET-1 and vWF in patients with OSAS before treatment were significantly higher than those after treatment and in control group (P 0.05). The results indicate that there were PTS in most patients with OSAS before treatment. The activity of platelet could be corrected, and the function of endotheliocyte could be repaired after CPAP treatment. It had certain effect in lightening the clinical symptoms. (authors)

The prevalence of congenital heart defects (CHD) in Kabuki syndrome ranges from 28% to 80%. Between January 2012 and December 2015, 28 patients had a molecularly proven diagnosis of Kabuki syndrome. Pathogenic variants in KMT2D (MLL2) were detected in 27 patients, and in KDM6A gene in one. CHD was diagnosed in 19/27 (70%) patients with KMT2D (MLL2) variant, while the single patient with KDM6A change had a normal heart. The anatomic types among patients with CHD included aortic coarctation (4/19 = 21%) alone or associated with an additional CHD, bicuspid aortic valve (4/19 = 21%) alone or associated with an additional CHD, perimembranous subaortic ventricular septal defect (3/19 = 16%), atrial septal defect ostium secundum type (3/19 = 16%), conotruncal heart defects (3/19 = 16%). Additional CHDs diagnosed in single patients included aortic dilatation with mitral anomaly and hypoplastic left heart syndrome. We also reviewed CHDs in patients with a molecular diagnosis of Kabuki syndrome reported in the literature. In conclusion, a CHD is detected in 70% of patients with KMT2D (MLL2) pathogenic variants, most commonly left-sided obstructive lesions, including multiple left-sided obstructions similar to those observed in the spectrum of the Shone complex, and septal defects. Clinical management of Kabuki syndrome should include echocardiogram at the time of diagnosis, with particular attention to left-sided obstructive lesions and mitral anomalies, and annual monitoring for aortic arch dilatation. © 2017 Wiley Periodicals, Inc.

Background. Defecography is used by a majority of colorectal surgeons for it is the only method for anatomic and dynamic studies of the act of defecation. The method provides information on different aspects of anorectal and pelvic floor function and offers the possibility of visualizing the development of anatomic abnormalities. Methods. We analyzed the defecography findings carried out at 56 patients (50 female and 6 male) from 24 to 83 years of age (the average age 58.3 years) with proctologic ailments such as: faecal incontinence, sensation of obstruction in the rectum, constipations, rectal prolapse, solitary ulceration of rectum. The values of Parks' angle (ARA - the anorectal angle) were measured at rest, at strain and during defecation. Other parameters measured included: duration of sphincter relaxation, overall duration of defecation, mobility of the pelvic diaphragm. Results. Abnormal values of Parks' angle at rest and at strain were found in patients with the following problems: faecal incontinence, sensation of obstruction in rectum and constipation. However, they did not turn out to be characteristic for patients with rectal prolapse. Defecography has helped to detect concomitant rectocele in patients suffering from constipation and sensation of obstruction in the rectum. Defecography has also proved to be effective in the evaluation of patients who suffered from solitary ulceration of rectum. During the examination of these patients it has been observed that Parks' angle in various phases of defecation has flattened. The duration of sphincter relaxation in the studied group was changeable and did not depend on the kind of pathology. Conclusions. Defecography is one of the examinations which can be helpful in the evaluation of patient's motor functions both before and after the operation. (author)
