This work was done on 40 patients with type 2 DM and 20 healthy subjects were taken as control group.The aim of this work is to study the relation of the echocardiographic left ventricular hypertrophy and QTc dispersion in patients with type 2 DM.The three studied groups regarding clinical chorioamnionitis revealed no statistically significant difference.Regarding neonatal outcome of studied groups, patients with a negative amniotic fluid culture but positive PCR (group 2) had a significantly higher rate of adverse outcome including low gestational age at birth, low birth weight, and significant neonatal morbidity than those with a negative amniotic fluid culture and negative PCR (group 1). However, no differences were found between patients with a negative culture but positive PCR (group 2) and those with a positive amniotic fluid culture regardless the results of PCR (group 3).SUMMARYPreterm premature rupture of membrane occurs in 3% of pregnancies and is responsible for approximately one-third of all preterm births.Preterm PROM is an important cause of perinatal morbidity and mortality.Recent studies suggest an association between Intrauterine infection and both preterm delivery and morbidity of preterm infant. U. Urealyticum is the microorganism most frequently isolated from amniotic fluid of women with preterm labour and PROM.U. urealyticum has been implicated in the genesis of clinical chorioamnioitis, puerperal endometritis, neonatal sepsis and bronchopulmonary dysplasia (chronic lung disease).U. urealyticum isolation in clinical specimens remains a challenge, microbial culture for this organism require special culture conditions and results are generally not availably in time for clinical management decisions.Recently PCR has became an optimal method for the rapid detection of U. urealyticum in clinical specimen.The aim of our study was to determine the frequency and clinical significance for the detection of U. urealyticum in patients with preterm premature rupture of membranes.Our study included 100 patients with preterm premature rupture of membranes with gestational age less than 35 weeks and singleton gestation.Patients participated in our study underwent full history taking and clinical examination.Amniotic fluid was collected by transabdominal amniocentesis guided by ultrasonography and was immediately examined for WBC,s count and sent for microbiologic culture. An aliquot of fluid was stored at -70°C for PCR examination.According to the results of amniotic fluid cultures and PCR for U. urealyticum patients divided into 3 groups:o Group 1: (n.=59) Those with a negative amniotic fluid culture and a negative PCR assay.o Group 2 (n.=15): Those with a negative amniotic fluid culture but a positive PCR for Ureaplasma urealyticum.o Group 3 (n.=26): Those with a positive amniotic fluid culture for microorganisms regardless of the results of PCR.Regarding maternal age of the studied groups, There was no significant differences in the mean age at amniocentesis among the 3 group of patients.The difference in the gestational age at amniocentesis among the 3 groups of patients was not statistically significant, however patients with a positive amniotic fluid culture regardless PCR (group 3) showed the lowest mean gestational age at amniocentesis among the 3 studied groups.Patients with a negative amniotic fluid culture but a positive PCR (group 2) had a significantly higher amniotic fluid white blood cell count than those with a negative amniotic fluid culture and a negative PCR. However, there was no significant difference in the amniotic fluid white blood cell count between patients with a negative amniotic fluid culture but positive PCR and those with a positive amniotic fluid culture.The three studied groups regarding clinical chorioamnionitis revealed no statistically significant difference.Regarding neonatal outcome of studied groups, patients with a negative amniotic fluid culture but positive PCR (group 2) had a significantly higher rate of adverse outcome including low gestational age at birth, low birth weight, and significant neonatal morbidity than those with a negative amniotic fluid culture and negative PCR (group 1).

US are modalities of choice for the initial imaging of the abdomen and pelvis in children, the technique is non-invasive and? most children can be examined without sedation. The lack of exposure to radiation is important and examination can be repeated at frequent interval if required.? Sensitivity in the detection of different groups of lymph node enlargement is definitely higher using CT (100%) than US (70%).? Regarding accuracy in the evaluation of extranodal lymphoma CT was better than US with a sensitivity of (95%) and specificity of (90.9%). CT in addition to visualizing lymph node enlargement, offer more information about the extent of the lesion with involvement of the intra-abdominal nodes and extranodal organs.? On gastrointestinal lymphoma US can be used as an initial approach whenever there is a clinical suspicion of the intestinal lymphoma. However, the US demonstration of the small bowel loops may be obscured by over lying air in the adjacent loops, there fore, negative US findings cannot excluded the diagnosis of intestinal lymphoma, with a sensitivity of (55.6%) and specificity of (71.4%).?

CT in addition to visualizing lymph node enlargement, offer more information about the extent of the lesion with involvement of the intra-abdominal nodes and extranodal organs.? On gastrointestinal lymphoma US can be used as an initial approach whenever there is a clinical suspicion of the intestinal lymphoma. However, the US demonstration of the small bowel loops may be obscured by over lying air in the adjacent loops, there fore, negative US findings cannot excluded the diagnosis of intestinal lymphoma, with a sensitivity of (55.6%) and specificity of (71.4%).? Regarding gastrointestinal lymphoma CT has been proven to be more sensitive than US in revealing bowel wall thickening with sensitivity of (100%), so CT must be performed for staging of the disease and assessment of the extension of the mass.Summary and ConclusionThis study included 30 patients, they were 20 males and 10 females and their age ranged from 1 year to 15 years old.Detailed personal history was taken, full clinical examination and laboratory investigation were performed prior imaging.Abdominal distention was the most common presentation seen in 53.3% of cases.Ultrasonography and abdominal computed tomograhpy were performed in all cases.NHL accounts for about 63.3% of cases and HD for about 36.7% of cases.The results of these diagnostic modalities were recorded, analyzed and compared to the final diagnosis.
