Poligrafía domiciliaria en pacientes con patología cardiovascular y sospecha de un SAHS / No disponible

OBJETIVOS: Validar la poligrafía domiciliaria en pacientes con comorbilidad vascular y sospecha de un síndrome de apneas hipopneas del sueño (SAHS) y determinar, en aquellos enfermos con cardiopatía isquémica, si el tratamiento con CPAP influye en el control de esta enfermedad. PACIENTES Y MÉTODOS: Fueron incluidos 42 enfermos (29 hombres y 13 mujeres, edad: 53 ± 7,8 años, IMC: 33 ± 5,2). Se les realizó poligrafía domiciliaria y polisomnografía convencional. Dieciséis pacientes con cardiopatía isquémica fueron evaluados tras el tratamiento con CPAP. El diagnóstico de SAHS se estableció ante un índice de apnea-hipopnea (IAH), en la polisomnografía> 5 y se indicó tratamiento con CPAP si el IAH fue > 15. RESULTADOS: Se observa una correlación y concordancia significativa (p < 0,01) entre la polisomnografía y poligrafía, en el IAH (36 ± 19,9 frente a 32 ± 17,4), r = 0,903 y CCI = 0,938, y en el índice de saturación (33 ± 23,5 frente a 35 ± 22,1), r = 0,896 y CCI = 0,948. Respecto a un IAH > 5 en la polisomnografía, la poligrafía obtiene un área bajo la curva ROC = 1 y para un IAH > 15el área bajo la curva ROC fue de 0,945. Tras el tratamiento con CPAP, los enfermos con cardiopatía isquémica acudieron menos frecuentemente al servicio de urgencias. CONCLUSIONES: La poligrafía domiciliaria es válida para el diagnóstico e indicación de tratamiento. En pacientes con cardiopatía isquémica, la CPAP mejora su control, descendiendo el número de consultas al servicio de urgencias (AU)

OOBJETIVES: To validate home poligraphy in patients with vascular comorbidity and suspicion of obstructive sleep apnea syndrome (OSAS), and to determine in patients with is chemicheart disease if treatment with CPAP influences in their control. PATIENTS AND METHODS: Forty-two patients were included (29 men and 13 women; Age: 53 ± 7.8 years; BMI: 33 ± 5.2)who were made home sleep study and conventional polysomnography. Sixteen patients with ischemic heart disease were evaluate dafter CPAP treatment. Diagnosis of OSAS was stablished when apnea-hypoapnea index (AHI) was > 5 in polysomnography and treatment with CPAP was indicated when AHI > 15. RESULTS: A significative correlation and concordance (p<0.01)were observed between the polysomnography and polygraphy in the AHI (36 ± 19.9 vs 32 ± 17.4), r = 0.903 and CCI = 0.938, and the desaturation index (33 ± 23.5 vs 35 ± 22.1), r = 0.896 and CCI = 0.948.When AHI >5 in polysomnography, the polygraphy obtained an are aunder the ROC curve = 1 and for IAH >15 the area under the ROC curve was 0.945. After CPAP treatment, patients with ischemic heart disease went less frequently to the hospital. CONCLUSIONS: Poligraphy is valid for diagnosis and treatment indication. Patients with ischemic heart disease, CPAP improves their control and reduces visits to the hospital (AU)

Cardiac tamponade secondary to pneumopericardium after lung transplantation: a case report.

Pneumopericardium is a rare cause of cardiac tamponade. It is an exceptional complication of lung transplantation. We have presented a case of a patient with cystic fibrosis who experienced cardiac tamponade secondary to a tension pneumopericardium during the postoperative course after lung transplantation. Dehiscence of the bronchial suture line was confirmed by fiberoptic bronchoscopy.

Trastornos del sueño en pacientes con hemodiálisis. Estudio polisomnográfico con grupo control / Sleep disfunctions in haemodialysis patients. Polysomnographic study with control group

Objetivos: Respecto a población sana, se evalúan los trastornos del sueño en enfermos con enfermedad renal crónica estadio 4-5 (ERC 4-5) y hemodiálisis. En estos últimos se estudia la prevalencia del síndrome de apneas-hipopneas del sueño (SAHS) y algún marcador analítico asociado independientemente al SAHS. Pacientes y Método: fueron estudiados 32 pacientes en hemodiálisis(24 hombres y 8 mujeres, edad: 54 ± 16, IMC: 25 ± 3.9), 14enfermos con ERC 4-5 y 14 sujetos sanos. Estos dos últimos grupos, pareados por edad, género e IMC con el grupo en hemodiálisis. Se les realizó una historia clínica y una polisomnografía diagnóstica, estableciéndose el diagnóstico de SAHS ante un índice deapnea-hipopnea (IAH) ? 10.Resultados: Respecto al grupo control sano, los pacientes con ERC 4-5 muestran peor calidad de sueño y un mayor IAH, aunque sin significación estadística, mientras el grupo en hemodiálisis presenta menos cantidad y peor calidad de sueño, un IAH significativamente elevado (4.3 ± 1.44 vs 19.1 ± 18.5, p:0.007) y un mayor número de descensos en la SaO2 (9.9 ± 5.15 vs 26.5 ± 17.81,p:0.011). Un 78% de los enfermos en hemodiálisis presentaban algún trastorno del sueño, destacando el SAHS (48%). La creatinina y el eKt/V se asociaron con el IAH (R2:0.219, p: 0.028).Conclusiones: El SAHS es frecuente en la IRC. Los pacientes en hemodiálisis muestran un elevado IAH y de hipoxia intermitente que deben evitarse en estos pacientes con mortalidad cardiovascular elevada. Únicamente las cifras de creatinina y eKt/ Vexplican parcialmente la variabilidad del IAH

Objetives: To evaluate the quality of the sleep and sleep disorders breathing in patients with chronic kidney disease stage 4-5(CKD4-5) and in hemodialysis respect healthy population. In addition, to study in these last ones, the prevalence of the obstructive sleep apnea-hypoapnea syndrome (SAHS) and the existence of some analytical marker associated to SAHS. Patients and methods: There were studied 32 patients with CKD in hemodialysis (24 men and 8 women, age of 54±16, BMI of25±3.9), 14 patients with CKD 4-5 and a group of 14 healthy subjects; these groups were matched for age, gender, and BMI with the hemodialysis group. All of them were studied with a clinical history and a overnight polisomnography. We stablished the diagnostic of SAHS when the apnea-hypoapnea index (AHI) ?10.Results: Patients with CKD 4-5 showed worse quality of sleep and more episodes of AHI respect healthy control group, although without statistic signification. The group in hemodialysis had less quantity and worse quality of sleep than the control group with an AHI significatly higher (4.3 ± 1.44 vs 19.1 ± 18.5, p:0.007) and more decreases of the SaO2 (9.9 ± 5.15 vs 26.5 ± 17.81, p:0.011).78% of the patients in hemodialysis suffered some sleep disorder, emphasizing the SAHS (48%). The serum creatinine and the eKt/ v were independently associated with the AHI (R2: 0.219, p: 0.028).Conclusions: The sleep disorder is a prevalent pathology in the CKD. Patients in hemodialysis show a elevated AHI and of intermittent hypoxia, that must be avoided in these patients with an elevated cardiovascular mortality. Only, the levels of creatinine and the eKt/v explain partially the variability of the AHI

A linkage map of chickpea (Cicer arietinum L.) based on populations from Kabuli x Desi crosses: location of genes for resistance to fusarium wilt race 0.

Two recombinant inbred line (RIL) populations derived from intraspecific crosses with a common parental line (JG62) were employed to develop a chickpea genetic map. Molecular markers, flower colour, double podding, seed coat thickness and resistance to fusarium wilt race 0 (FOC-0) were included in the study. Joint segregation analysis involved a total of 160 markers and 159 RILs. Ten linkage groups (LGs) were obtained that included morphological markers and 134 molecular markers (3 ISSRs, 13 STMSs and 118 RAPDs). Flower colour (B/b) and seed coat thickness (Tt/tt) appeared to be linked to STMS (GAA47). The single-/double-podding locus was located on LG9 jointly with two RAPD markers and STMS TA80. LG3 included a gene for resistance to FOC-0 (Foc0(1)/foc0(1)) flanked by RAPD marker OPJ20(600) and STMS marker TR59. The association of this LG with FOC-0 resistance was confirmed by QTL analysis in the CA2139 x JG62 RIL population where two genes were involved in the resistance reaction. The STMS markers enabled comparison of LGs with preceding maps.
