We reported a young patient with myelodysplastic syndrome (MDS) with eosinophilia, in which her chromosomal analysis revealed the presence of trisomy X and a marker chromosome at chromosome 11. The technique used to detect the chromosomal abnormalities is a multicoloured –fluorescent in situ hybridization technique (M-FISH). Our observation suggested that these underlying chromosomal abnormalities were probably responsible for her development of MDS with eosinophilia.
Myelodysplastic syndrome (MDS) is a condition whereby there is ineffective production of haematopoietic stem cells and poor quality of cells produced. The cause can either be a primary bone marrow problem, de novo or therapy related. Most MDS cases are secondary rather than primary. Many chromosomal abnormalities have been found in cases of myelodysplastic syndrome. We described a case of MDS with eosinophilia in association with presence of trisomy X and a marker chromosome in chromosome 11.

Fulltext Significance of a clean-tip catheter closed suctioning system in a high-setting ventilated, super morbidly obese patient with profuse respiratory secretions

INTRODUCTION: Closed suctioning is commonly used in the context of high-setting mechanical ventilation (MV), given its ability to prevent lung volume loss that otherwise accompanies open suctioning. However, closed suctioning systems (CSS) are not equivalent regarding components and capabilities, and thus this technique may be differentially effective to adequately clear patient secretions from an endotracheal tube (ETT), which is of paramount importance when the tube size makes the ETT particularly vulnerable to block by patient secretions.
CASE PRESENTATION: A 25-year-old super morbidly obese female (body mass index = 55 kg/meter2) presented with worsening shortness of breath. For MV, pairing of a 6 mm (mm) diameter ETT to accommodate the patient's vocal cord edema, with a CSS not designed to maintain a clean catheter tip, precipitated ETT blockage and respiratory acidosis. Replacement of these devices with a 6.5 mm ETT and a CSS designed to keep the catheter tip clean resolved the complications. After use of the different ETT and CSS for approximately one week, the patient was discharged to home.
DISCUSSION: The clean-tip catheter CSS enabled a more patent airway than its counterpart device that did not have this feature. Use of a clean-tip catheter CSS was an important care development for this patient, because this individual's super morbidly obese condition minimized tolerance for MV complications that would exacerbate her pre-existing tenuous respiratory health status.
CONCLUSION: Special attention should be given to the choices of ETT size and CSS to manage super morbidly obese patients who have a history of difficult airway access.

Fulltext Advanced paternal age effect on trisomy X syndrome

Advanced parental age is a risk factor for chromosomal abnormalities in their offspring. Trisomy X or Triple X syn- drome has previously been reported with advanced maternal age. Here we report two (2) cases of Trisomy X with paternal age as risk factor. Generally, Trisomy X individuals show variable physical and psychological manifesta- tions. However, both cases reported here have advanced paternal age as a risk factor; 55 years old (46 years old at conception) for Case 1 with patient having right eye squint, beaked nose, Posterior Misalignment Type Ventricular Septal Defect (PMVSD) and small Patent Ductus Arteriosus (PDA) with failure to thrive and 49 years old (45 years old at conception) for Case 2 with speech delay and protruding tongue. In view of that, advanced paternal age could possibly contribute the accumulation of de novo mutations in germ line mosaicism.
