Authors: Saha Shudhanshu Kumar , Islam Rafi Nazrul , Rahim Muhammad Abdur , Iqbal Sarwar 
Published: August 2020

Background: Anemia and mineral bone disorders (MBD) accompany chronic kidney disease (CKD) and worsen as CKD progresses. Different biochemical parameters of CKD-MBD have been associated with anemia of CKD but are less well evaluated in low resource settings. In this study, we evaluated the role CKD-MBD disorders as a cause of anemia in CKD non-dialysis patients.
Methods: This cross-sectional study recruited 115 patients with CKD who attended outpatient department (OPD) of Nephrology in BIRDEM General Hospital between January and June 2019. Patients, who were on iron, erythropoietin, calcium or vitamin D therapy in any form within the preceding 3 months and patients with known parathyroid disorders, metabolic bone diseases or anemia with definite etiology were excluded. Each patient’s demographic, clinical and biochemical parameters were recorded. Associations between anemia and serum levels of calcium (corrected), phosphate, parathyroid hormone (PTH), 25-hydroxy vitamin D [25(OH)D] and alkaline phosphatase were evaluated.
Results: Total patients were 115 including 71 (61.7%) females. Mean age was 57.8 years. Most patients were in CKD stage 4 (43, 37.4%) and 5 (45, 39.1%). Mean duration of diabetes and hypertension were 12.7 and 7.2 years respectively. Mean serum creatinine (mg/dL), hemoglobin (gm/dL), calcium (mg/dL), albumin (gm/L), phosphate (mg/dL), alkaline phosphatase (U/L), PTH (pg/mL) and 25(OH)D (ng/mL) were 3.1, 10.5, 8.7, 37.9, 4.0, 119.1, 211.1 and 15.1 respectively. Hemoglobin in CKD stages 3-5 pre-dialysis patients had positive correlation with calcium and 25(OH)D and negative correlation with phosphate, alkaline phosphatase and PTH. Among these parameters of CKD-MBD, correlation with alkaline phosphatase was significant (r=-0.352, p=0.001)
Conclusion: Anemia in CKD patients is multifactorial and this study concludes that CKD-MBD is yet another entity contributing to anemia in such pre-dialysis patients.

Authors: Chowdhury Tanzeem S , Mahtab Naushaba Tarannum , Mahmud Syeda Rifat , Chowdhury TA 
Published: August 2020

Twin-to-twin transfusion syndrome (TTTS) is an obstetric condition with high perinatal mortality, which develops when blood flows disproportionately from one fetus to another in a monochorionic twin pregnancy. Approximately 1 in 7 monochorionic pregnancies are affected with TTTS. The donor twin develops oligohydramnios and poor fetal growth, while the recipient twin develops polyhydramnios, heart failure and hydrops. Here we report two cases of severe TTTS in BIRDEM General Hospital 2 within a period of two years. It has been observed in different studies that, the mortality rate of both twins can be as high as 80% in TTTS depending on the stage of diagnosis and progression of the condition if untreated. In both our cases, the outcome was poor due to delayed diagnosis and lack of intrauterine therapies. So, there is an urgent need for timely diagnosis and appropriate management of this rare but complex condition which prompted us to report these two cases.

Published: August 2020

Norwegian scabies is characterized by hyperkeratotic, heavily scaling, crusted lesions rarely presents as exfoliative dermatitis (erythroderma). This term applies when 90% or more of the skin surface is involved by scabies. A 75-year-old woman having uncontrolled diabetes mellitus and hypertension was admitted in BIRDEM general hospital with generalized erythroderma for 6 months and high fever along with vomiting for 4 days. Clinical and laboratory findings were suggestive of severe sepsis with septic shock, which were being managed by supportive medications. Microscopic examination of scales and crusts dissolved in 10% KOH revealed fields teeming with scabies mites and eggs. A skin biopsy was planned but could not be done due to critical condition of the patient. Despite of all supportive measures, patient expired due to septic shock before starting definitive treatment of Norwegian scabies.

La figura de la víctima
Authors: Alejandro Murad Omar 
Published: August 2020

En nuestros días la figura de la víctima gobierna una buena parte de las intervenciones públicas de colectivos e individuos que no solo se asocian con minorías o grupos subalternos, sino que también gobierna el discurso de instituciones, colectivos e individuos que tienen un lugar consolidado en el statu quo. Una mirada rápida sobre la cuestión descartaría el uso de esta figura como una estrategia para generar agencia, puesto la víctima se caracteriza por su pasividad. Sin embargo, el caso es que su utilización en el espacio público habilita ciertas prerrogativas en el agente que la invoca, al mismo tiempo que lo coloca en una posición que no necesariamente se caracteriza por su pasividad sino que, al contrario, la figura dota al agente de posibilidades de acción muy específicas. En particular, en este trabajo nos proponemos poner en discusión este punto de vista considerando algunos ejemplos de negacionismo en torno al carácter de la víctima en cuanto tal. La negación de la víctima a partir de la disputa de su posición por parte de sus victimarios nos pone sobre aviso de un tipo de intervención verbal que tiene como ámbito de discusión a la figura de marras.
En este trabajo proponemos, por una parte, historizar esta figura a partir del trazado de su genealogía, utilizando como insumos teóricos los estudios de Rene Girard y, por la otra, analizar retóricamente algunos casos ejemplares en los que se hace visible el tipo de agencia que caracteriza su uso. Para ello, nos serviremos de ejemplos tomados de la literatura de la historia y de las ciencias sociales y del movimiento feminista.

The results of laboratory and field estimate of stability of newly created potato breeding material against Globodera rostochiensis (Ro1) are presented. During 2016—2018, 640 breeding samples sent by the leading breeding institutions of the state, namely: the Institute for Potato Research of the NAAS of Ukraine, the Polessky research department the Institute for Potato Research of the NAAS, CJSC NGO “Chernihivelitkartoplya” and the Institute of agriculture of the Carpathian region were tested in laboratory conditions. Among the potato material we studied, most of the samples belonged to the Polessky research department the Institute for Potato Research of the NAAS — 305 (47.7% of the total), where 172 samples (56.4%) of the sent hybrids of the first and second year of the testing were resistance. A higher percent of the resistance of the breeding material was in the potato material of the Institute for Potato Research of the NAAS, which was 68.0% (115 breeding numbers). In laboratory conditions, most of the samples — 57.7% showed resistance to golden potato cyst nematode (GPCN), 16.2% of the samples were weakly resistant and the rest samples — 26.1% of potato hybrids were classified as susceptible. During the field testing, 32 samples were tested, of which 28 were classified as resistance, 2 selective samples were weakly resistant and 2 were susceptible. The majority of resistance selection material on the high-invasive background showed high nematode cleanse ability and good yield, which exceeded control in 1.5—2 times. All resistant forms are a valuable material for introducing into the breeding process for the production of nematode resistant potato varieties, which will keep the crop in the infected areas and will have the ability to clear the soil from golden nematode potatoes.
