ABSTRACT

The value of abdominal computed tomography in non-traumatic abdominal pain has been well established. On the other hand, to manage computed tomography, appropriateness has become more of an issue as a result of the concomitant increase in patient radiation exposure with increased computed tomography use. The purpose of this study was to investigate whether C-reactive protein, white blood cell count, and pain location may guide the selection of patients for computed tomography in non-traumatic acute abdomen. Patients presenting with acute abdomen to the emergency department over a 12-month period and who subsequently underwent computed tomography were retrospectively reviewed. Those with serum C-reactive protein and white blood cell count measured on admission or within 24 h of the computed tomography were selected. Computed tomography examinations were retrospectively reviewed, and final diagnoses were designated either positive or negative for pathology relating to presentation with acute abdomen. White blood cell counts, C-reactive protein levels, and pain locations were analyzed to determine whether they increased or decreased the likelihood of producing a diagnostic computed tomography. The likelihood ratio for computed tomography positivity with a C-reactive protein level above 5 mg/L was 1.71, while this increased to 7.71 in patients with combined elevated C-reactive protein level and white blood cell count and right lower quadrant pain. Combined elevated C-reactive protein level and white blood cell count in patients with right lower quadrant pain may represent a potential factor that could guide the decision to perform computed tomography in non-traumatic acute abdomen.

ABSTRACT

Exposure of the fetus to medical radiation sources during the diagnostic procedures without intention is one of the most significant concerns in the medical community. In this study, 45 conventional X-ray and computed tomography (CT) examinations of the women who were unaware of their pregnancy were investigated. Effective doses and fetal doses were calculated for each application by using PCXMC and ImPACT CT scan software. The exposure of abdominal CT and abdominal conventional X-ray examinations was found to be over the literature for both the range and the average values. Average effective dose for abdominal CT examinations was calculated to be ∼3.1 times higher than that in the literature. For abdominal CT and conventional X-ray examinations, the mean fetal doses were found to be ∼3.5 times and ∼5.4 times higher than those in the literature, respectively.

ABSTRACT

This case report aimed to describe the fabrication procedure and treatment efficacy of an individual, one-piece, non-adjustable mandibular advancement device (MAD) for a moderate obstructive sleep apnoea patient with facial paralysis (FP). Mandibular advancement device was fabricated with autopolymerising acrylic resin. The intermaxillary relations were recorded such as to fix the mandible at a protruded position with increased vertical dimension. Initial evaluation of the MAD was made with axial magnetic resonance imaging and polysomnography on the first day of usage. Following evaluations were made on the third and sixth month. After a follow-up period of 6 months, Apnoea/Hypopnea Index (AHI) significantly decreased from 26·7 to 3·0. However, the average oxygen saturation did not improve as expected initially. The MAD therapy decreased the AHI scores of a patient with FP. At the end of a follow-up period of 6 months, the patient did not report any serious complaint except temporary tooth pains.
