Improved Care for Rh-Isoimmunized Patients in Saudi Arabia

Abstract

Although the number of patients with Rh isoimmunization in pregnancy has been decreasing in recent years, this category of patients contributes significantly to the perinatal mortality in Saudi Arabia. Recent advances in obstetric ultrasound and immunology have added new knowledge on how to manage this category of patients, and today almost all Rh-affected fetuses are potentially salvageable. This article presents these advances and discusses the implications they might have on perinatal care in Saudi Arabia.

Late hyporegenerative anemia in neonates with rhesus hemolytic disease

“…However, Rh hemolytic disease is still a major contributing factor to the morbidity of newborn infants admitted to the NICU at King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia [6]. Rh hemolytic disease presents in its severe form in affected Saudi infants, possibly because of grand multiparity and failure to receive anti-D immunoglobulin at the time of exposure to the antigens [6,12]. Rh hemolytic disease presents in its severe form in affected Saudi infants, possibly because of grand multiparity and failure to receive anti-D immunoglobulin at the time of exposure to the antigens [6,12].…”

Fe3Mo3N: Crystal Structure, High‐Temperature Behavior, and Catalytic Activity for Ammonia Decomposition

“…The corresponding structure type is that of Fe 3 W 3 C, also called η‐carbide type. A description of this structure type as filled Ti 2 Ni structure can be found too [10,11] . The cell parameter is a =11,0777 Å and 16 formular units are in the unit cell, further details of the results of the Rietveld refinement are given in Table 1.…”

Boron induced structure modifications in Pd–Cu–B system: new Ti2Ni-type derivative borides Pd3Cu3B and Pd5Cu5B2

“…The Ti 2 Ni structure 1 6 ] octahedral voids (16d, ½,½,½) ), 2 innumerable examples of phases containing two or more transition metals and carbon, 3-11 nitrogen [12][13][14][15] or oxygen [16][17][18][19][20][21] have been observed including fully ordered quaternary examples such as Ti 3 NiAl 2 N and others 22 . More recently, the complex Ti 2 Nitype metal nitrides and hydrides attract a considerable attention as promising catalytic 23,24 and hydrogen storage 25,26 materials, respectively.…”

“…The most distinguished feature of the Ti 2 Ni-type structure is a rich variety of interstitial sites available for small atoms of the elements like H, C, N, O. Since Westgren's first determination of the so called η-carbide structure W 3 Fe 3 C (filled up derivative of Ti 2 Ni with C in [W 6 ] octahedral voids (16d, 1 2 , 1 2 , 1 2 )), 2 innumerable examples of phases containing two or more transition metals and carbon, [3][4][5][6][7][8][9][10][11] nitrogen [12][13][14][15] or oxygen [16][17][18][19][20][21] have been observed including fully ordered quaternary examples such as Ti 3 NiAl 2 N and others. 22 More recently, the complex Ti 2 Ni-type metal nitrides and hydrides attract a considerable attention as promising catalytic 23,24 and hydrogen storage 25,26 materials, respectively.…”
