Selected AbstractsMetastatic basal cell carcinoma: rapid symptomatic response to Cisplatin and PaclitaxelANZ JOURNAL OF SURGERY, Issue 8 2004Michael Jefford Background: Basal cell carcinoma (BCC) is the most common cancer in the community, although it rarely metastasizes. The literature reports less than 100 patients who have received chemotherapy for metastatic BCC. A further case of this rare disease is reported here. The pattern of disease in the reported patient was similar to that described in the literature, but the patient experienced a long period with untreated metastatic disease compared with that in the literature. Method: The patient was treated with cisplatin in combination with paclitaxel. Literature review suggests this to be the first report of this combination. Results: Rapid symptomatic response was achieved though late neurotoxicity occurred. Conclusion: This regimen is an active combination for the rare patient with metastatic BCC. The combination of carboplatin and paclitaxel causes less neurotoxicity and may therefore be a superior regimen. [source] A genetic polymorphism in the coding region of the gastric intrinsic factor gene (GIF) is associated with congenital intrinsic factor deficiency,HUMAN MUTATION, Issue 1 2004Marilyn M. Gordon Abstract Congenital intrinsic factor (IF) deficiency is a disorder characterized by megaloblastic anemia due to the absence of gastric IF (GIF, GenBank NM_005142) and GIF antibodies, with probable autosomal recessive inheritance. Most of the reported patients are isolated cases without genetic studies of the parents or siblings. Complete exonic sequences were determined from the PCR products generated from genomic DNA of five affected individuals. All probands had the identical variant (g.68A>G) in the second position of the fifth codon in the coding sequence of the gene that introduces a restriction enzyme site for Msp I and predicts a change in the mature protein from glutamine5 (CAG) to arginine5 (CGG). Three subjects were homozygous for this base exchange and two subjects were heterozygous, one of which was apparently a compound heterozygote at positions 1 and 2 of the fifth codon ([g.67C>G] + [g.68A>G]). The other patient, heterozygous for position 2, had one heterozygous unaffected parent. Most parents were heterozygous for this base exchange, confirming the pattern of autosomal recessive inheritance for congenital IF deficiency. cDNA encoding GIF was mutated at base pair g.68 (A>G) and expressed in COS-7 cells. The apparent size, secretion rate, and sensitivity to pepsin hydrolysis of the expressed IF were similar to native IF. The allelic frequency of g.68A>G was 0.067 and 0.038 in two control populations. This sequence aberration is not the cause of the phenotype, but is associated with the genotype of congenital IF deficiency and could serve as a marker for inheritance of this disorder.

All the reported patients with lissencephaly are males who presented with a posterior-to-anterior gradient, moderately increased thickness of the brain cortex, agenesis of corpus callosum, micropenis, and cryptorchidism. We describe the neurosonographic findings associated with the XLAG syndrome. To our knowledge, the association between XLAG and lenticulostriate vasculopathy has not been reported before. © 2008 Wiley Periodicals, Inc.

We report three cases of corrosion carcinoma seen by us (a team of gastroenterologists, radiologists and a surgeon) in the last 15 years. Two cases were among 156 patients with corrosive induced strictures on our follow-up, and constituted the only corrosion carcinoma out of 650 esophageal carcinomas operated on by us. Nearly all reported patients with corrosion carcinoma in the published literature had consumed an alkali, but two of our three patients had consumed an acid. [source] Recessive congenital methaemoglobinaemia: functional characterization of the novel D239G mutation in the NADH-binding lobe of cytochrome b5 reductaseBRITISH JOURNAL OF HAEMATOLOGY, Issue 6 2005M. J. Percy Summary Type I recessive congenital methaemoglobinaemia (RCM), caused by the reduced form of nicotinamide adenine dinucleotide (NADH)-cytochrome b5 reductase (cytb5r) deficiency, manifests clinically as cyanosis without neurological dysfunction. Two mutations, E255- and G291D, have been identified in the NADH-binding lobe of cytb5r in previously reported patients, and we have detected a further novel mutation, D239G, in this lobe in two unrelated Irish families. Although one family belongs to the genetically isolated Traveller Community, which separated from the general Irish population during the 1845,48 famine, the D239G mutation was present on the same haplotype in both families. Three known cytb5r mutations were also identified, including the R159- mutation, which causes loss of the entire NADH-binding lobe and had previously been reported in an individual with type II RCM. Characterization of the three NADH-binding lobe mutants using a heterologous expression system revealed that all three variants retained stoichiometric levels of flavin adenine dinucleotide with spectroscopic and thermodynamic properties comparable with those of native cytb5r. In contrast to the E255- and G291D variants, the novel D239G mutation had no adverse impact on protein thermostability. The D239G mutation perturbed substrate binding, causing both decreased specificity for NADH and increased specificity for NADPH. Thus cytb5r deficient patients who are heterozygous for an NADH-binding lobe mutation can exhibit the clinically less severe type I phenotype, even in association with heterozygous deletion of the NADH-binding lobe. [source] A review of high-dose intravenous immunoglobulin (hdIVIg) in the treatment of the autoimmune blistering disordersCLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 2 2001S. Jolles High-dose intravenous immunoglobulin (hdIVIg) is being used increasingly for dermatological indications. Its mode of action is via a number of proposed mechanisms and it is not associated with the many side-effects of steroids and other immunosuppressive agents. The evidence for using hdIVIg in the treatment of autoimmune bullous disorders is based on uncontrolled trials and case reports. However, there are now 62 reported patients and this review aims to make a critical assessment of the current data. This has been obtained from a Medline search of the English literature from 1966 to 2000 for pemphigus vulgaris, pemphigus foliaceus, bullous pemphigoid, pemphigoid gestationis, cicatricial pemphigoid, epidermolysis bullosa acquisita and linear IgA disease. Taken together hdIVIg was effective in 81% of the patients with blistering disease. Patients appear to be more likely to respond when hdIVIg is used as adjunctive therapy (91% response rate) than as monotherapy (56% response rate). hdIVIg may offer a safe potential therapeutic avenue for resistant cases of the autoimmune bullous disorders but should be further assessed using double-blind placebo-controlled trials. [source] Phenotypic variability in isodicentric Y patients: study of nine casesCLINICAL GENETICS, Issue 2 2006M DesGroseilliers Isodicentric chromosomes are the most commonly reported aberrations of the human Y chromosome. As they are unstable during cell division and can generate various types of cell lines, most reported patients are chromosomal mosaics, generally including a 45,X cell line. Phenotypes depend on the location of the breakpoints as well as on the proportion of each cell line and vary from male to abnormal female or individual with ambiguous genitalia. Although phenotypic variability is known to also depend on the degree of mosaicism in the various tissues, gonads are rarely studied. We report nine cases of isodicentric Y chromosomes studied by conventional and molecular cytogenetic: three males, five females, and one individual with sexual ambiguity. Two males had a non-mosaic karyotype, while the third male was a mosaic with a predominant 46,XY cell line. Three of the females had a major 45,X cell line, while the last two females and the patient with ambiguous genitalia had a major 46,X,idic(Y) cell line. Analyses of gonadal tissues from the individual with sexual ambiguity and of three of the five female patients gave results concordant with their phenotype, allowing us to better understand the sexual differentiation of these patients.
