Natural history of pelvic organ prolapse in symptomatic patients actively seeking treatment.

INTRODUCTION AND HYPOTHESIS: At our institution many symptomatic patients must wait months or years for surgery. Our aim was to determine the rates of clinically significant pelvic organ prolapse (POP) progression and identify risk factors associated with POP progression. METHODS: Data from a prospectively maintained database of POP patients evaluated between 2008 and 2013 were analyzed. Women with symptomatic POP and two or more POP-Q examinations prior to surgery were included. POP progression was defined as having any of the POP-Q points Aa, Ba, C, D, Ap or Bp above the hymen at the baseline examination and at or below the hymen at the follow-up examination. Multivariable logistic analysis was preformed and the results are presented as odds ratios (OR) with 95% confidence intervals (CI). RESULTS: Of consecutive patients evaluated between July 2008 and June 2013, 388 met the inclusion criteria and were included. The median time between the POP-Q examinations was 9.9 months (IQR 7.8 to 13.8 months). The POP progression rate was 29.1% (95% CI 24.6-33.6%). Predictors of progression included age (OR 1.7, 95% CI 1.01-2.87) and the baseline status of points Ba, C, Bp and gH (OR 1.91, 95% CI 1.01-3.62; OR 0.53, 95% CI 0.3-0.94; OR 0.54, 95% CI 0.32-0.93; OR 2.15, 95% CI 1.13-4.1; respectively). POP-Q point correlations showed that anterior and posterior compartment points evolve with apical compartment points and gH evolves with both the anterior compartment and the apex. CONCLUSIONS: Up to 29.1% of symptomatic patients with POP showed clinically significant progression over a median follow-up of 9.9 months. The likelihood of progression was not significantly associated with time. Those ≥60 years of age as well as those with point Ba ≥4 cm or gH ≥5 cm at baseline were at increased risk of POP progression.

Association between pelvic floor disorder symptoms and QoL scores with depressive symptoms among pelvic organ prolapse patients.

BACKGROUND: There is no consensus on the relationship between depressive symptoms (DS) and pelvic organ prolapse (POP) symptoms and quality of life (QoL). Our hypothesis was that women with DS and POP have worse symptoms and QoL than those without DS and POP. AIM: Our aim was to compare two groups of POP patients, those with depressive symptoms and those without, and evaluate the association of symptoms and QoL. MATERIALS AND METHODS: This planned report is part of a prospective study evaluating the impact of pessary use among symptomatic POP patients. Patients were evaluated by POP quantification (POP-Q), pelvic ultrasound (US), voiding diaries, stress test, pad test, Pelvic Floor Distress Inventory (PFDI-20), Prolapse QoL (P-QoL) and the Goldberg Health Questionnaire (GHQ-12) (psychological health screening for DS when score ≥5). A sample size of 78 patients was required to demonstrate a 50-point difference in the global PFDI-20 score with 80% power and 95% probability. RESULTS: Ninety-one women with POP were included. GHQ-12 was positive in 47 (51.6%) patients. No differences were found in POP-Q, pad and stress test between those with a positive GHQ-12 and those without. However, GHQ-12 was associated with higher PFDI-20 scores and higher scores in seven of nine P-QoL domains. GHQ-12 persisted as an independent risk factor for worse P-QoL scores after multivariable analysis. CONCLUSION: A 'positive' screening for DS was associated with worse PFDI-20 and P-QoL scores despite no difference in objective measurements. It may be that depressed patients interpret their symptoms differently.

[Burnout syndrome in medical and obstetric perception of violence]. / Síndrome de desgaste profesional en médicos y percepción de la violencia obstétrica.

BACKGROUND: Obstetric violence involves a violation of reproductive rights of women during pregnancy, childbirth and postpartum. It has been associated with lack of empathy and emotional discomfort of physicians. OBJECTIVE: To identify the perceptions of obstetric violence and to determine the possible relationship with burnout syndrome. MATERIAL AND METHODS: We evaluated 29 physicians whose scope of work relates to obstetrics and gynecology. The evaluation instruments were: a) questionnaire on professional perception that collects demographic information, situations of perceived obstetric violence, major concerns of physicians in their professional work, and includes an scale about level of job satisfaction, b) the Maslach Burnout inventory, and c) Jefferson Scale of Physician Empathy. RESULTS: The most prevalent obstetric violence situations perceived were: medical malpractice and harmful practices (10/29), discrimination (10/29), rude treatment and verbal attacks (11/29). Seventeen participants reported lack of information on obstetric violence and not have tools to cope with this problem. Regarding the burnout syndrome, it was associated with several items of the scale of empathy and with the scale of job satisfaction. CONCLUSIONS: This study shows the importance of providing knowledge and tools to deal with obstetric violence and stress management to prevent such situations on medical practices.

Optimal length of triple therapy for H pylori eradication in a population with high prevalence of infection in Chile.

AIM: To compare the efficacy of 7-d versus 14-d triple therapy for the treatment of H pylori infection in Chile, with a prevalence of 73% in general population. METHODS: H pylori-infected patients diagnosed by rapid urease test, with non-ulcer dyspepsia or peptic ulcer disease were randomized to receive omeprazole 20 mg bid, amoxicillin 1 g bid, and clarithromycin 500 mg bid for 7 (OAC7) or 14 (OAC14) d. Primary outcome was eradication rate 6 wk after the treatment. Subgroup analysis was carried out considering the eradication rate among patients with or without peptic ulcer disease and eradication rate among smokers or non-smokers. RESULTS: One hundred and thirty-one patients were randomized to OAC7 (n = 69) or OAC14 (n = 62). The overall eradication rate (intention-to-treat) was 78.3% in OAC7 and 85.5% in OAC14 groups, without a significant difference (P =0.37). No significant difference in the eradication rate was found among the patients with peptic ulcer disease (n = 31) between the OAC7 group (85.7%) and OAC14 group (87.5%). However, smokers had an obviously lower eradication rate compared to non-smokers, particularly in the OAC7 group (57.1% in smokers vs 83.6% in non-smokers; P = 0.06). Adverse effects rate were similar between both groups. CONCLUSION: Short-term efficacy of triple therapy with OAC for 7 d is comparable to 14 d in this high-prevalence population. Longer follow-up, and studies focused to some subgroups of patients (smokers and non-ulcer patients) are necessary to support widespread use of 7-d instead of 10-14-d triple therapy in a developing country like Chile.

Value of adenosine deaminase (ADA) in ascitic fluid for the diagnosis of tuberculous peritonitis: a meta-analysis.

BACKGROUND AND GOALS: Adenosine deaminase (ADA) levels are used for diagnosing tuberculosis in several locations and although many studies have evaluated ADA levels in ascitic fluid. These studies have defined arbitrary cut-off points creating difficulties in the clinical application of the results. The goals of this study are: to determine the usefulness of ADA levels in ascitic fluid as a diagnostic test for peritoneal tuberculosis (PTB) and define the best cut-off point. STUDY: A systematic review was done on the basis of 2 independent searches. We selected prospective studies that included consecutive patients. Diagnosis of PTB had to be confirmed by bacteriologic or histologic methods and ADA levels determined by the Giusti method. Inclusion/exclusion criteria were applied by 2 independent reviewers. A receiver operating characteristic curve was constructed to establish the optimal cut-off point and the likelihood ratios (LRs) estimated using fixed-effect pooled method. RESULTS: Twelve prospective studies were found. Four of them met the inclusion criteria and were thus included in the meta-analysis. They included 264 patients, of which 50 (18.9%) had PTB. ADA levels showed high sensitivity (100%) and specificity (97%) using cut-off values from 36 to 40 IU/L. The included studies were homogeneous. Optimal cut-off point was determined at 39 IU/L, and LRs were 26.8 and 0.038 for values above and below this cut-off. CONCLUSIONS: This study supports the proposition that ADA determination is a fast and discriminating test for diagnosing PTB with an optimal cut-off value of 39 IU/L.

Incidence and prevalence of hepatitis C virus infection in Chile.

UNLABELLED: Chronic hepatitis C is a major cause of liver-related morbidity and mortality. Epidemiological data regarding this infection in developing countries is scanty. METHODS: Prevalence of hepatitis C (HCV) infection was investigated in a random sample of Chilean general adult population older than 20 years of age. Additionally, frequency of HCV infection was assessed in group of native Chilean Amerindians (Mapuche Indians) living in an isolated locality of the Southern Chile. Incidence of HCV infection was estimated using serum samples separated by 7 years (1993-2000). RESULTS: Among 959 subjects, prevalence of anti-HCV antibodies was 1.15% (95% CI 0.48-1.82%) and 0.83% when only RIBA-confirmed cases were considered. Among these subjects, 62.5% had detectable HCV RNA in serum and 40% of them had a history of blood transfusion. Age distribution of cases showed a steadily increasing prevalence with age. Estimated incidence of new HCV infections was 15 per 100,000 subjects per year in the period 1993-2000. No cases were detected among the 145 Mapuche subjects studied. CONCLUSIONS: HCV infection is a prevalent disease in the Hispanic population of Chile with a low incidence in the last decade, whereas it was not detected in an isolated Mapuche Indian community. Age distribution of prevalence suggests that the peak of infection in Chile occurred 30 to 50 years ago.

Cuantificación de hormonas tiroideas y tirotropina en niños críticamente enfermos con septisemia / Quantification of the thyroid hormones and thyrotropine in critically-ill septicemic children

Estudiamos la función hipotálamo, hipofisiaria, tiroidea en 23 niños críticamente enfermos con septicemia y 15 controles sin patología que afectara dicho eje. La comparación de los resultados de las cuantificaciones de 3,3'5-triiodotironina (T3), 3,3'-5'-triiodotironina evidenció franca disminución de T3 y T4 y elevación de T3r y TSH en los septicémicos, con diferencia estadísticamente significativa (P<0.001). Estas alteraciones bioquímicas que traducen un mecanismo del organismo para mantener la homeostasis y evitar el cataolismo, mediante la conservación de energía, mostraron su normalización espontánea en 18 sobrevivientes de los niños septicémicos al recuperarse
