[Complex case with respiratory, endocrine and digestive manifestations--late complications after a colic replacement of the esophagus for lye ingestion]. / Caz complex cu tulburari respiratorii, endocrine si digestive--complicatii tardive post-esofagoplastie cu colon pentru ingestie de soda caustica.

Long term complications after colic replacement of the esophagus are well known and their managment is known as being difficult, due to multiple associated comorbidities; we present the case of a 26-year-old patient with multiple late complications after a coloesophagoplaty for lye ingestion during childhood. The patient finally died despite all the eforts of treatement during a prolonged hospitalisation. We will try to analyse the key moments on patient's evolution and discuss other possible options in this case.

[The present and future prospects in rapid molecular diagnosis of tuberculosis and MDR-TB (First Part)]. / Prezent si perspective în diagnosticul rapid molecular al tuberculozei si al MDR-tB (prima parte).

Tuberculosis is still one of the diseases with a major medical and social impact, and in terms of early diagnosis (which would imply a fair treatment and established at the time), difficulties related to the delay bacilli isolation in culture, decreased susceptibility testing methods to antituberculosis drugs, lack of methods for differentiation of M. Tuberculosis complex germs of non TB Mycobacteria, may have important clinical implications. Traditional testing of anti-TB drug susceptibility on solid Löwenstein-Jensen medium (gold standard) or liquid media can only be performed using grown samples. Determining the time it takes up to 42 days on solid media and 12 days for liquid media. For MDR/XDR TB cases is absolutely essential to reduce the detection time. In these cases prove their usefulness rapid diagnostic methods. Automatic testing in liquid medium, molecular hybridization methods are currently recommended by the current WHO guidelines. Rapid diagnosis of MDR-TB is extremely useful for the early establishment of an effective treatment tailored more accurately on the spectrum of sensitivity of the resistant strain (thus reducing the risk of developing additional resistance to other drugs) and control the spread of these strains. Genetic diagnostic methods, approved and recommended by the WHO, can reduce the time of diagnosis of TB case and, importantly, the case of MDR TB. They do not replace the current standard diagnostic methods and resistance profile, but complete them in selected cases.

[Proportion and site distribution of extrarespiratory tuberculosis in 2007-2010 in Romania]. / Ponderea si structura pe localizari a tuberculozei extrarespiratorii in perioada 2007-2010 în România.

In the actual context of an increased TB endemia (notification rate of 90.5 per thousand, meaning 21457 cases in 2010, but with a constant decreasing trend in the last 8 years), we wanted to see what is the share and structure of extra-respiratory tuberculosis in the period 2007-2010. In the interval 2007-2010 have been registered annually between 1252-1267 extra-respiratory TB cases. Extra-respiratory TB have been between 30% and 42,1% from all TB cases registered annually with the extra-pulmonary TB. In the descending order of cases recorded with TB extra respiratory in 2010, the first was extra-thoracic ganglionary TB (244 cases), followed by osteo-articulary (233) and those of meningo-encephalitis and CNS TB (133). Location of TB on the spine remains the most common form of skeletal TB, representing 62.2% (145 cases) of all osteo-articulary locations. The number of registered cases of pericardial effusions TB annually remains steady at 40-50 cases. The number still high of meningo encephalitis TB (severe prognosis, epidemiological severity) involves enhanced accountability measures in TB control of the territory. The collaboration between the pulmonologist and the body specialist constitutes compulsory condition of quality assistance in case of TB extra respiratory sites.

Trendelenburg chest optimization prolongs spontaneous breathing trials in ventilator-dependent patients with low cervical spinal cord injury.

Chest optimization, an evidence-based protocol-guided multimodal chest physiotherapy consisting of body positioning, sputum mobilization, bronchodilation, and lung hyperinflation, may be routinely administered to ventilator-dependent patients with low cervical spinal cord injury (CSCI) for improving pulmonary functional outcomes that facilitate weaning from mechanical ventilation. We undertook this study to determine whether position-specific chest optimization was associated with changes in spontaneous breathing trial (SBT) duration. Cardiac output (CO), alveolar minute volume (MValv), carbon dioxide elimination (VCO(2)), and static chest compliance (Cst) were measured during chest optimization; then MValv and rapid shallow breathing index (RSBI) were measured during SBT. Study participants (N = 12) were clinically stable ventilator-dependent patients with low CSCI. Trendelenburg chest optimization (TCO) was associated with significant increases in SBT (p < 0.001), CO (p < 0.001), MValv (p < 0.003), VCO(2) (p < 0.001), and Cst (p < 0.002). SBT following TCO was associated with significant increases in MValv (p < 0.03) and RSBI (p < 0.002). These preliminary findings suggest the importance of proper recumbent body positioning during evidence-based, protocol-guided multimodal chest physiotherapy for ventilator-dependent patients with low CSCI.

[Tuberculosis in Romania between 2006-2008]. / Tuberculoza in România intre anii 2006-2008.

The high level of TB incidence places Romania among first places in Europe and on the first place in European Union; in the last years a slowly, but hopefully descending trend can be observed (from 114.2 per hundred thousand in 2006 to 109.8 per hundred thousand in 2007 and 108 per hundred thousand in 2008). TB incidence in children has also decreased from 31.6 per hundred thousand in 2006 to 30.8 per hundred thousand in 2007 and 28.5 per hundred thousand in 2008. TB mortality decreased to 7.8 per hundred thousand in 2006 and 7.4 per hundred thousand in 2007. Every year, 800 cases with MDR TB are notified in Romania. The results obtained in the cohort of new patients with pulmonary SS(+) tuberculosis: the success rate reached in 2003 was 79.5% and 83.9% in 2006. The success rate was greater in pulmonary patients confirmed by culture: 82% in 2003 and 85.5% in 2006. In conclusion, the results of NTP implementation in Romania, reflected by the evolution of the principal epidemio-metrical indicators (decrease of the global incidence, TB incidence at children, TB mortality and increase of therapeutical successes) confirms the TB control activities efficacy.

Quantitative fluorescence in situ hybridization and its ability to predict bladder cancer recurrence and progression to muscle-invasive bladder cancer.

Fluorescence in situ hybridization (FISH) testing is used to detect bladder cancer in urine specimens. The purpose of this study was to determine whether there are associations between the percentage of chromosomally abnormal cells by FISH and time to bladder cancer recurrence and progression to metastasis. Clinical records were searched to identify patients with urine FISH results, history of non-invasive bladder cancer, and at least one follow-up pathological diagnosis. Covariates analyzed included age, gender, smoking status, treatment after FISH, cystoscopy result, and prior stage of bladder cancer. The percentage of abnormal cells (hazard ratio [HR] 1.03, 95% CI 1.02-1.03; P < 0.001), age (HR 1.02, 95% CI 1.00-1.03; P = 0.033), male gender (HR 0.60, 95% CI 0.41-0.87; P < 0.001), treatment (HR 0.37, 95% CI 0.25-0.55; P < 0.001), and history of TIS/T1-stage tumors (HR 1.66, 95% CI 1.23-2.24; P = 0.001) were significantly associated with time to cancer recurrence. Time to invasive cancer was significantly associated with the percentage of abnormal cells (HR 1.02, 95% CI 1.01, 1.03; P < 0.001), history of TIS/T1 tumor (HR 3.73, 95% CI 1.88, 7.38; P = 0.001), and treatment (HR 0.33, 95% CI 0.13, 0.83; P = 0.019), suggesting that the percentage of abnormal cells independently predicts cancer recurrence and progression to invasive disease in patients with a history of non-invasive bladder cancer.

[Multidrug resistant tuberculosis in Romania in the last years (2004-2007)--an extremely important social phenomenon]. / Tuberculoza multidrog rezistenta în România în ultimii ani (2004-2007)--un fenomen social de maxima importanta.

The emergence of resistance to drugs used to treat tuberculosis (TB), and particularly multidrug resistant (MDR-TB) strains, has become a significant public health problem in a number of countries and an obstacle to effective global TB control. In many other countries, the extent of drug resistance is unknown and the management of the patients with MDR-TB is inadequate. In countries where drug resistance has been identified, specific measures need to be taken within TB control programmes to address the problem through appropriate management of patients and adoption of strategies to prevent the propagation and dissemination of drug resistant TB, including MDR-TB. In Romania there are two centers for the management of MDR-TB cases: one in Bucharest at The National Pneumology Institute "Marius Nasta" and the other at Bisericani (Neamt district). The comparative analysis of MDR-TB cases and under treatment evolution was done, in the two excellence centers Bucharest and Bisericani from 2004 to 2007. This is a retrospective study of MDR-TB patients enrolled in Romania between 2004-2007. All patients evaluated were managed under The National Tuberculosis Programme approved protocols and had the opportunity to receive more than 24 months of treatment. In addition, follow-up data on successfully treated patients were collected at the beginning of 2007. This study is based on an MDR register, and a software collecting information on MDR-TB cases. In order to be accepted in one of the two MDR centers, patients need to fulfill certain criteria to improve the treatment results. A total number of 305 MDR-TB patients were registered at the beginning of 2007 in Bucharest MDR center; this study used a number of 170 MDR-TB patients from Bucharest who fulfilled the study's criteria in oppose to the 294 MDR-TB patients from Bisericani. 184 patients from the first cohort of DOTS-Plus project were evaluated until the end of the study: 55 were completed treatment and 54 cured, which means 59,23% succes rate. The conversion rate of culture at 4 months (for the first cohort) in MDR excellence centers was: Bucharest--72,5% and Bisericani--64%.

Dietary fat and cholesterol and the risk of cardiovascular disease among women with type 2 diabetes.

BACKGROUND: Nutritional therapy is a cornerstone of diabetes management, but no epidemiologic studies have investigated the relation between specific dietary fatty acids and cholesterol and cardiovascular disease (CVD) risk among diabetic patients. OBJECTIVE: This study assessed the relation between specific dietary fatty acids and cholesterol and CVD risk among women with type 2 diabetes. DESIGN: Among 5672 women with type 2 diabetes from the Nurses' Health Study, diet was assessed prospectively and updated periodically. Relative risks of CVD were estimated from Cox proportional hazards analysis after adjustment for potential confounders. RESULTS: Between 1980 and 1998, we identified 619 new cases of CVD (nonfatal myocardial infarction, fatal coronary heart disease, and stroke). The relative risk (RR) of CVD for an increase of 200 mg cholesterol/1000 kcal was 1.37 (95% CI: 1.12, 1.68; P = 0.003). Each 5% of energy intake from saturated fat, as compared with equivalent energy from carbohydrates, was associated with a 29% greater risk of CVD (RR: 1.29; 95% CI: 1.02, 1.63; P = 0.04). The ratio of polyunsaturated to saturated fat (P:S) was inversely associated with the risk of fatal CVD. We estimated that replacement of 5% of energy from saturated fat with equivalent energy from carbohydrates or monounsaturated fat was associated with a 22% or 37% lower risk of CVD, respectively. CONCLUSIONS: A higher intake of cholesterol and saturated fat and a low P:S were related to increased CVD risk among women with type 2 diabetes. Among diabetic persons, replacement of saturated fat with monounsaturated fat may be more effective in lowering CVD risk than is replacement with carbohydrates.

Physical activity in relation to cardiovascular disease and total mortality among men with type 2 diabetes.

BACKGROUND: The present study was conducted to examine the relationship of physical activity with risk of cardiovascular disease (CVD) and mortality among men with type 2 diabetes. CVD risk and mortality are increased in type 2 diabetes. Few epidemiological studies have investigated the effect of physical activity on these outcomes among type 2 diabetics. METHODS AND RESULTS: Of the 3058 men who reported a diagnosis of diabetes at age 30 years or older in the Health Professionals' Follow-up Study (HPFS), we excluded 255 who reported a physical impairment. In the remaining 2803 men, physical activity was assessed every 2 years; 266 new cases of CVD and 355 deaths of all causes were identified during 14 years of follow-up. Relative risks of CVD and death were estimated from Cox proportional hazards analysis with adjustment for potential confounders. The multivariate relative risks of CVD incidence corresponding to quintiles of total physical activity were 1.0, 0.87, 0.64, 0.72, and 0.67 (Ptrend=0.07). The corresponding multivariate relative risks for total mortality were 1.0, 0.80, 0.57, 0.58, and 0.58 (Ptrend=0.005). Walking was associated with reduced risk of total mortality. Relative risks across quintiles of walking were 1.0, 0.97, 0.87, 0.97, and 0.57 (Ptrend=0.002). Walking pace was inversely associated with CVD, fatal CVD, and total mortality independently of walking hours. CONCLUSIONS: Physical activity was associated with reduced risk of CVD, cardiovascular death, and total mortality in men with type 2 diabetes. Walking and walking pace were associated with reduced total mortality.

Exercise type and intensity in relation to coronary heart disease in men.

CONTEXT: Studies have shown an inverse relationship between exercise and risk of coronary heart disease (CHD), but data on type and intensity are sparse. OBJECTIVE: To assess the amount, type, and intensity of physical activity in relation to risk of CHD among men. DESIGN, SETTING, AND PARTICIPANTS: A cohort of 44 452 US men enrolled in the Health Professionals' Follow-up Study, followed up at 2-year intervals from 1986 through January 31, 1998, to assess potential CHD risk factors, identify newly diagnosed cases of CHD, and assess levels of leisure-time physical activity. MAIN OUTCOME MEASURE: Incident nonfatal myocardial infarction or fatal CHD occurring during the follow-up period. RESULTS: During 475 755 person-years, we documented 1700 new cases of CHD. Total physical activity, running, weight training, and rowing were each inversely associated with risk of CHD. The RRs (95% confidence intervals [CIs]) corresponding to quintiles of metabolic equivalent tasks (METs) for total physical activity adjusted for age, smoking, and other cardiovascular risk factors were 1.0, 0.90 (0.78-1.04), 0.87 (0.75-1.00), 0.83 (0.71-0.96), and 0.70 (0.59-0.82) (P<.001 for trend). Men who ran for an hour or more per week had a 42% risk reduction (RR, 0.58; 95% CI, 0.44-0.77) compared with men who did not run (P<.001 for trend). Men who trained with weights for 30 minutes or more per week had a 23% risk reduction (RR, 0.77; 95% CI, 0.61-0.98) compared with men who did not train with weights (P =.03 for trend). Rowing for 1 hour or more per week was associated with an 18% risk reduction (RR, 0.82; 05% CI, 0.68-0.99). Average exercise intensity was associated with reduced CHD risk independent of the total volume of physical activity. The RRs (95% CIs) corresponding to moderate (4-6 METs) and high (6-12 METs) activity intensities were 0.94 (0.83-1.04) and 0.83 (0.72-0.97) compared with low activity intensity (<4 METs) (P =.02 for trend). A half-hour per day or more of brisk walking was associated with an 18% risk reduction (RR, 0.82; 95% CI, 0.67-1.00). Walking pace was associated with reduced CHD risk independent of the number of walking hours. CONCLUSIONS: Total physical activity, running, weight training, and walking were each associated with reduced CHD risk. Average exercise intensity was associated with reduced risk independent of the number of MET-hours spent in physical activity.
