    Notes: Abstract The notions of ‘early-onset’ and ‘prepubertal’ anorexia nervosa are reviewed, with particular reference to the role of the pubertal process within the condition.A database of 650 female cases is utilized to identify a small sub-group (n= 30) who developed the condition before the menarche. Many clinical, familial, social and precipitating factors distinguish this group from post-pubertal cases as a whole, and a sub-group of post-menarcheal cases (n= 42) matched for age.An explanation for previous inconsistent findings in‘early-onset’ and ‘prepubertal’ anorexia nervosa is advanced.

    Pulsed laser heating of silicon-nitride capped GaAs: Optical properties at high temperature (1988)

    Notes: The optical properties of silicon nitride and gallium arsenide were studied at temperatures up to and beyond the melting point of GaAs by means of laser heating. XeCl excimer and pulsed dye laser pulses, ∼10 ns in duration, were used to heat the semiconductor under nitride capping layers of varying thickness. The transient reflectivity response at 514.5 nm was used together with a multilayer interference analysis to obtain the optical constants of solid and molten GaAs and of solid Si3N4 near the 1513-K melting point of GaAs. In addition, we report the melt duration as a function of laser pulse energy for GaAs with and without capping layers.

    Notes: Carrier concentrations exceeding 1019/cm3 in GaAs implanted with Si (2×1014/cm2 at 140 keV) have been obtained by pulsed laser annealing with either a dye laser (λ=728 nm) or a XeCl excimer laser (λ=308 nm). Dye-laser annealing through a ∼55-nm-thick Si3N4 cap consistently produced higher activations than excimer-laser annealing with or without the cap. Carrier densities were measured by phonon-Raman and plasmon-Raman scattering.

    Notes: Antitryptic and antichymotryptic activities in amniotic fluid and maternal serum were measured at various stages of pregnancy using the caseinolytic assay method for proteases. The inhibitory activities increased up to 20 weeks in amniotic fluid and remained in the same range up to 30 weeks; a sharp fall was observed at term. In serum, there was a gradual rise of activities with peak values around 30 weeks. The decrease with further advance of pregnancy was not as sharp as in amniotic fluid. The ratios of antitryptic to antichymotryptic activities remained fairly constant (1 54±0.07) in amniotic fluid throughout pregnancy. In maternal serum the ratio varied over a range of 1.28 to 2.67 and the increase in antichymotryptic activity was relatively greater between 16 and 30 weeks resulting in a lower ratio between the two activities. Amniotic fluid was found to contain a higher proportion of a heat stable inhibitor compared to serum and its contribution to total antitryptic activity variedfrom8.7 to 15.6 percent.

    Notes: Serum and amniotic fluid samples from five pregnant women were analyzed for different proteinase inhibitors by ion-exchange chromatography on DEAEcellulose. Alpha-2 macroglobulin was found to be absent in amniotic fluid. Even though α-1 antichymotrypsin was identified in amniotic fluid, its concentration gradient between serum and amniotic fluid (20–60) was much higher than that of α-1 antitrypsin (8–20). Two forms of α-1 antitrypsin were identified in both the fluids. In pregnancy, the ratio of the two forms was altered in favour of the less anionic form compared to normal sera. The contribution of the heat stable proteinase inhibitor for total antitryptic activity in amniotic fluid was more than in serum. The observation that urine samples from immature infants had higher heat stable inhibitory activity than urine samples from normal infants suggests that the heat stable inhibitor in amniotic fluid may arise from fetal kidney.

    Notes: Abstract Five different complexes of nickel(II) withanti-2-furancarboxaldoxime (β-FDH) have been prepared and characterized by elemental analysis, molecular weights, conductance studies, magnetic moments and infra-red spectral studies. These are [Ni(FDH)4Cl2], [Ni(FD)2(FDH)], [Ni(FD)2(FDH)2], [Ni(FD)2·en], and [Ni(FD)2]. All the complexes are neutral monomeric, paramagnetic (μ=3.3–3.7 μB) and may be considered octahedral except the complex [Ni(FD)2], (μ=2.92 μB) which is tetrahedral. In these complexes the ligand functions as a monodentate and/or bidentate, coordinating with furan oxygen and oxime oxygen in the latter case. The ligand has been shown to be present in the ionized, and/or unionized form in these complexes.

    Anterior cervical allograft arthrodesis and instrumentation: Multilevel interbody grafting or strut graft reconstruction (1997)

    Notes: Abstract This retrospective study evaluated a single surgeon's series of patients treated by multilevel cervical disc excision (two or three levels), allograft tricortical iliac crest arthrodesis, and anterior instrumentation. The objective of this retrospective study was to compare fusion success and clinical outcome between multilevel Smith-Robinson interbody grafting and tricortical iliac strut graft reconstruction, both supplemented with anterior instrumentation in the cervical spine. The incidence of nonunion for cervical discectomy and fusion varies widely depending on the number of disc levels involved, type of bone graft used, and whether the anterior grafting is supplemented with instrumentation. An alternative to multilevel interbody fusion is corpectomy and strut grafting, in which the incidence of nonunion has been reported to be 27% with autograft and 41% with allograft. Sixty-four consecutive patients who underwent allograft tricortical iliac crest reconstruction and anterior cervical plating were studied. The average follow-up was 39 months. There were 38 patients in the discectomy and interbody grafting group and 26 patients in the corpectomy and strut graft reconstruction group. Pseudoarthrosis occurred in 42% of the anterior cervical interbody fusion patients and 31% of the corpectomy patients. Nonunion in two-level interbody fusions occurred in 36% of the patients as compared to 10% for patients with one-level corpectomies; while 54% of patients with three-level interbody fusions and 44% of patients with two-level corpectomies were noted to have pseudoarthrosis. Higher percentages of nonunion were noted in multilevel interbody grafting than in corpectomy with strut grafting and when more vertebral levels were involved. These radiographic and clinical findings underscore the shortcomings of multilevel anterior cervical allograft reconstruction with plating. Corpectomy may be the preferred method when multiple disc levels are fused. In addition, anterior corpectomy affords decompression of significant osteophytes in a safer and quicker manner. In retrospective studies, there is a need for long-term follow-up before accurate statements can be made about the study population.

    Notes: Abstract Various conditions such as fracture, dislocation, tumor, or infection adversely affect the vertebral body and lead to instability. Restoration of a stable anterior column is essential for normal spinal biomechanics. Various biological and mechanical spacers have been used to reconstruct the anterior column after corpectomy. In this retrospective review, the authors evaluated clinical charts and radiographs of 13 patients receiving titanium surgical mesh (TSM)-bone graft composite to reconstruct the anterior spinal column in the thoracic or lumbar region. The objective of this review was to evaluate the stability and efficacy of the TSM-bone graft composite in the anterior spine after a complete or partial corpectomy. Sixteen patients with involvement of the thoracic or lumbar vertebral column after trauma, tumor, or infection underwent partial or complete corpectomy. In all patients the anterior defect was reconstructed using a TSM-bone graft composite. Three patients died within 12 months postoperatively due to primary malignant process. Thirteen of 16 patient charts and radiographs were evaluated for anterior fusion status, settling of the TSM-bone graft composite, and hardware failure. No pseudoarthroses were noted. Evidence of solid anterior fusion was noted in all patients. The average settling of the TSM-bone graft construct was 3 mm. All patients presenting with only pain and no neurological symptoms (n = 9) experienced early pain relief. For patients presenting with neurological symptoms (n = 4), the recovery was complete in three and partial in one. No patient was made neurologically worse, and there were no vascular injuries intra- or postoperatively. The study suggests that TSM-bone graft composite offers excellent biomechanical stability in the immediate postoperative period, permitting progressive maturation of the fusion mass.
