Chronic Immune Thrombocytopenia and Hashimoto’s Hypothyroidism in an Adolescent: Presentation and Implications

Immune thrombocytopenia (ITP) is a disorder characterized by immune-mediated destruction of thrombocytes leading to peripheral blood platelet count of <100 × 10^9/L. Primary ITP is a terminology used in the absence of other causes or disorders that may be associated with thrombocytopenia, i.e., isolated thrombocytopenia. The term secondary ITP is used if such diseases coexist. We present here a case of a 14-year-old female diagnosed with immune thrombocytopenia. When her evaluation was not strongly supportive of primary ITP, she was screened and proved to have a concomitant Hashimoto thyroiditis. Contrary to the popular belief about secondary ITP in adult population, treatment of our patient’s hypothyroidism did not improve her platelet’s count, and the patient needed multiple immunosuppressive medications to improve her condition

Lupus cystitis in an Omani girl

Systemic Lupus Erythematosus (SLE) is an autoimmune disease characterized by multiple organs involvement. Bladder involvement (Lupus cystitis) is a rare manifestation of SLE, and occurs in association with gastrointestinal manifestations. We report a case of lupus inters-titial cystitis with bladder irritation and bilateral hydroureteronephrosis in an adolescent female who was treated with intravenous methylprednisolone pulse therapy followed by oral pred-nisolone and mycofenolate mofetil (MMF). Her symptoms ameliorated, and the hydrouretero-nephrosis improved. She was presented again with systemic flare up of the disease together with hydrouretronephrosis, but without bladder irritation symptoms. The diagnosis of lupus cystitis was confirmed by radiographic abnormalities, cystoscopy and bladder biopsy

Mixed Bartter-Gitelman syndrome: an inbred family with a heterogeneous phenotype expression of a novel variant in the CLCNKB gene

Patients with renal diseases associated with salt-losing tubulopathies categorized as Gitelman and classic form of Bartter syndrome have undergone genetic screening for possible mutation capture in two different genes: SLC12A3 and CLCNKB. Clinical symptoms of these two diseases may overlap. Bartter syndrome and Gitelman syndrome are autosomal recessive salt-losing tubulopathies with hypokalemia, metabolic alkalosis, hyperreninemia, hyperplasia of the juxtaglomerular apparatus, hyperaldosteronism, and, in some patients, hypomagnesemia. Here we describe four patients from an inbred family with a novel missense variant in the CLCNKB gene. All of patients are asymptomatic; yet they have the typical metabolic abnormality of salt losing tubulopathies. One of those patients had hypomagnesaemia while others not. Clinical and laboratory data of all patients was described. All 4 patients have a homozygous c.490G > T missense variant in exon 5 of the CLCNKB gene. This variant alters a glycine into a cysteine on amino acid position 164 of the resulting protein (p.Gly164Cys). The c.490G > T variant is a novel variant not previously described in other patients nor controls. Polyphen analysis predicts the variation to be possibly damaging. Analysis of SLC12A3 was normal. Here in we are describing a novel homozygous c.490G > T missense variation was identified in exon 5 of the CLCNKB gene was identified in an Emirati patients with a mild manifestation of Bartter - Gitelman syndrome

Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC): Report of three cases with a novel mutation in CLDN19 gene

Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a rare autosomal recessive disorder that is caused by mutation in the genes coding for tight junction proteins Claudin-16 and Claudin-19. Affected individuals usually develop nephrocalcinosis and progressive renal failure; some of them may have ophthalmologic involvement as well. Phenotypic description of three affected individuals from the same Middle Eastern kindred (two sisters and their cousin) is presented. This includes both clinical and laboratory findings upon initial presentation and subsequent follow-up. Molecular analysis of the CLDN19 gene was performed on the three cases and one set of parents. A novel homozygous missense mutation in CLDN19 (c.241C>T, p.Arg81Cys) was detected in all three affected children. The parents were heterozygous. Clinical and laboratory data in the three children with renal and ocular manifestations of FHHNC are described. Genetic analysis revealed a novel mutation in the CLDN19 gene. FHHNC is a rare cause of nephrocalcinosis, and we believe that it should be considered in the presence of nephrocalcinosis with hypercalcuria and hypermagnesuria

Unique Mutation in SP110 Resulting in Hepatic Veno-Occlusive Disease with Immunodeficiency

Familial hepatic veno-occlusive disease with immunodeficiency (VODI, OMIM: 235550) is a rare form of combined immune deficiency (CID) that presents in the first few months of life with failure to thrive, recurrent infections, opportunistic infections along with liver impairment. Herein, we are describing a Pakistani patient with a homozygous novel variant in the SP110 gene, presenting with classical phenotypic manifestations of VODI. He presented at the age of 3 months with opportunistic infections and later developed liver failure. Conclusion. Hepatic veno-occlusive disease with immunodeficiency is a rare cause of immunodeficiency, and this is the first case report from the Middle East in a patient of Pakistani origin. It is important to have a high suspicion for this disease, in patients presenting early life with a picture of CID and deranged liver function, as the earlier the diagnosis and treatment, the better the prognosis

Synergistic corrosion inhibition effect of metal cations and mixtures of organic compounds: A Review

Solomon, Moses/0000-0002-3251-8846WOS: 000398950800028The devastating effect of corrosion on the structural integrity of metals surfaces has been of great concern for some time. However, the challenge is to develop a benign and cost effective inhibitor that is highly effective. Addition of substances that exert synergistic influence and blending of different metals inhibitors had been employed. This review article delineates the effect of addition of metals cations and blending on the inhibition efficiency of metals corrosion inhibitors. The mechanisms proposed for the synergistic inhibition resulting from either addition of metals cations or blending are also discuss based on reported experimental data. (C) 2016 Elsevier Ltd.
