Thalassemia, a human blood disorder / Talassemia, uma doença do sangue humano

A group of inherited blood defects is known as Thalassemia is among the world's most prevalent hemoglobinopathies. Thalassemias are of two types such as Alpha and Beta Thalassemia. The cause of these defects is gene mutations leading to low levels and/or malfunctioning α and β globin proteins, respectively. In some cases, one of these proteins may be completely absent. α and β globin chains form a globin fold or pocket for heme (Fe++) attachment to carry oxygen. Genes for alpha and beta-globin proteins are present in the form of a cluster on chromosome 16 and 11, respectively. Different globin genes are used at different stages in the life course. During embryonic and fetal developmental stages, γ globin proteins partner with α globin and are later replaced by β globin protein. Globin chain imbalances result in hemolysis and impede erythropoiesis. Individuals showing mild symptoms include carriers of alpha thalassemia or the people bearing alpha or beta-thalassemia trait. Alpha thalassemia causes conditions like hemolytic anemia or fatal hydrops fetalis depending upon the severity of the disease. Beta thalassemia major results in hemolytic anemia, growth retardation, and skeletal aberrations in early childhood. Children affected by this disorder need regular blood transfusions throughout their lives. Patients that depend on blood transfusion usually develop iron overload that causes other complications in the body systems like renal or hepatic impairment therefore, thalassemias are now categorized as a syndrome. The only cure for Thalassemias would be a bone marrow transplant, or gene therapy with currently no significant success rate. A thorough understanding of the molecular basis of this syndrome may provide novel insights and ideas for its treatment, as scientists have still been unable to find a permanent cure for this deadly disease after more than 87 years since it is first described in 1925.

Um grupo de defeitos sanguíneos hereditários é conhecido como talassemia e está entre as hemoglobinopatias mais prevalentes do mundo. As talassemias são de dois tipos, como talassemia alfa e beta. As causas desses defeitos são as mutações genéticas que levam a níveis baixos e/ou proteínas de globina com mau funcionamento, respectivamente. Em alguns casos, uma dessas proteínas pode estar completamente ausente. As cadeias de globina α e β formam uma dobra ou bolsa de globina para a fixação de heme (Fe ++) para transportar oxigênio. Os genes das proteínas alfa e beta globina estão presentes na forma de um cluster nos cromossomos 16 e 11, respectivamente. Diferentes genes de globina são usados em diferentes estágios do curso de vida. Durante os estágios de desenvolvimento embrionário e fetal, as proteínas γ globina se associam à α globina e, posteriormente, são substituídas pela proteína β globina. Os desequilíbrios da cadeia de globina resultam em hemólise e impedem a eritropoiese. Indivíduos que apresentam sintomas leves incluem portadores de talassemia alfa ou as pessoas com traços de talassemia alfa ou beta. A talassemia alfa causa condições como anemia hemolítica ou hidropsia fetal fatal, dependendo da gravidade da doença. A beta talassemia principal resulta em anemia hemolítica, retardo de crescimento e aberrações esqueléticas na primeira infância. As crianças afetadas por esse distúrbio precisam de transfusões de sangue regulares ao longo da vida. Os pacientes que dependem de transfusão de sangue geralmente desenvolvem sobrecarga de ferro que causa outras complicações nos sistemas do corpo, como insuficiência renal ou hepática, portanto as talassemias agora são classificadas como uma síndrome. A única cura para as talassemias seria um transplante de medula óssea ou terapia genética sem atualmente uma taxa de sucesso significativa. Uma compreensão completa da base molecular dessa síndrome pode fornecer novos insights e ideias para seu tratamento, [...].

The impact of cow dung augmentation on soil restoration and bio-accumulation of metals (Lead and Cadmium) in Pheretima posthuma (Annelida: Clitellata) / O impacto do aumento de esterco de vaca na restauração do solo e bioacumulação de metais (chumbo e cádmio) em Pheretima posthuma (Annelida: Clitellata)

To investigate the role of cow dung in soil reclamation and bio assimilation along with bio accumulation of heavy metals in earthworm (P. posthuma) (N=900) earthworms were used and treatment groups of CD-soil mixture of different proportion of cow dung were designed. Nonlethal doses of lead acetate and cadmium chloride were added in treatment groups. Mature P. posthuma were released in each experimental pot maintaining the favorable conditions. The pH, carbon, nitrogen, phosphorus, exchangeable cations, and heavy metal level of each mixture was evaluated. The results indicated that bio-assimilation of Pb and Cd by P. posthuma were significantly (P ˂ 0.01) higher in different soil-CD treatments compared to control. Highest bio-assimilation of both metals was observed in T¹ of both groups (Pb = 563.8 mg/kg and Cd = 42.95 mg/kg). The contents of both metals were significantly (P ˂ 0.05) lowered in casting. The nutrient concentration in the final castings of all soil-CD treatments were also equally transformed from less or insoluble to more soluble and available for plants, except for carbon level which increased with CD proportion. It is concluded that cow dung as organic matter has a positive effect on soil reclamation and bio-assimilation of metals by P. posthuma.

Para investigar o papel do esterco de vaca na recuperação do solo e bioassimilação, juntamente com a bioacumulação de metais pesados em minhocas (P. posthuma) (N = 900), minhocas foram usadas e grupos de tratamento de mistura CD-solo de diferentes proporções de esterco de vaca foram projetados. Doses não letais de acetato de chumbo e cloreto de cádmio foram adicionadas aos grupos de tratamento. P. posthuma maduros foram liberados em cada vaso experimental, mantendo as condições favoráveis. Foram avaliados o pH, carbono, nitrogênio, fósforo, cátions trocáveis e nível de metais pesados de cada mistura. Os resultados indicaram que a bioassimilação de Pb e Cd por P. posthuma foi significativamente (P ˂ 0,01) maior em diferentes tratamentos de solo-CD em relação ao controle. A maior bioassimilação de ambos os metais foi observada em T1 de ambos os grupos (Pb = 563,8 mg / kg e Cd = 42,95 mg / kg). O conteúdo de ambos os metais foi significativamente (P ˂ 0,05) reduzido na fundição. A concentração de nutrientes nas fundições finais de todos os tratamentos de solo-CD também foi igualmente transformada de menos ou insolúvel para mais solúvel e disponível para as plantas, exceto o nível de carbono que aumenta com a proporção de CD. Conclui-se que o esterco de vaca como matéria orgânica tem um efeito positivo na recuperação do solo e na bioassimilação de metais por P. posthuma.

Isolation and characterization of bacteria residing in the oral, gut, and fecal samples of different pheasant species / Isolamento e caracterização de bactérias residentes nas amostras orais, intestinais e fecais de diferentes espécies de faisão

There is a paucity of research conducted on microbial prevalence in pheasants. The microbiota of captive birds has zoonotic significance and must be characterize. Present study is therefore planned to assess the microbiota from oral, fecal and gut content of captive avian species. It will be helpful in characterization of harmful microbes. Different samples taken from oral, gut and feces of ring-necked pheasants (Phasianus colchicus), green pheasants (Phasianus versicolor), golden pheasant (Chrysolophus pictus) and silver pheasant (Lophura nycthemera). Samples were collected, diluted, and inoculated onto different agar plates (MacConkey, SS agar, MSA and nutrient agar) for cultivation of bacterial species. Colonies of E.coli, Staphylococcus spp. Brachyspira spp. and Campylobacter spp were observed based on colony morphology. Colony forming unit showed E. coli as frequently found bacteria in fecal, oral and gut contents of all the above pheasants. The overall significance difference was found among bacterial species of golden pheasants, green pheasant, ring-necked pheasant, and silver pheasants. It was concluded that E.coli is predominant isolated from heathy pheasants followed by Campylobacter, Staphylococcus and Brachyspira.

Há uma escassez de pesquisas realizadas sobre a prevalência microbiana em faisões. A microbiota de aves em cativeiro tem significado zoonótico e deve ser caracterizada. O presente estudo está, portanto, planejado para avaliar a microbiota do conteúdo oral, fecal e intestinal de espécies aviárias em cativeiro. Será útil na caracterização de micróbios nocivos. Diferentes amostras retiradas da boca, intestino e fezes de faisões de pescoço redondo (Phasianus colchicus), faisões verdes (Phasianus versicolor), faisões dourados (Chrysolophus pictus) e faisão prateado (Lophura nycthemera). As amostras foram coletadas, diluídas e inoculadas em diferentes placas de ágar (MacConkey, ágar SS, MSA e ágar nutriente) para o cultivo de espécies bacterianas. Colônias de E. coli, Staphylococcus spp., Brachyspira spp. e Campylobacter spp foram observados com base na morfologia da colônia. A unidade formadora de colônia mostrou E. coli como bactéria frequentemente encontrada no conteúdo fecal, oral e intestinal de todos os faisões acima. A diferença de significância geral foi encontrada entre as espécies bacterianas de faisões dourados, faisões verdes, faisões de pescoço anelado e faisões prateados. Verificou-se que a E.coli é predominantemente isolada de faisões saudáveis, seguida por Campylobacter, Staphylococcus e Brachyspira.

Ecological impacts of climate change on the snow leopard (Panthera unica) in South Asia / Impactos ecológicos da mudança climática no leopardo-da-neve (Panthera uncia) no sul da Ásia

Snow leopard (Panthera unica) is a felid which lives in the highly rugged areas of alpine regions in different mountain ranges of South and Central Asia. This solitary animal needs large spaces for its ranges but due to climate change and relatively faster rate of global warming in South Asian mountain ranges, its habitat is going to shrink and fragment by tree-line shifts and change in hydrology of the area. Vegetative modification of montane flora and competition with domestic goats will create its prey's population to decline along with a chance of a direct conflict and competition with the common leopard. Common leopard being more adaptable, grouped, and larger in size can be a significant stressor for a smaller and solitary snow leopard. Habitat would shrink, and snow leopard can possibly move upslope or northward to central Asian ranges and their predicted migratory patterns are unknown.

O leopardo-das-neves (Panthera uncia) é um felídeo que vive nas áreas altamente acidentadas das regiões alpinas, em diferentes cadeias de montanhas do sul e do centro da Ásia. A revisão atual tem o objetivo de abordar a questão da possível perda de hábitat do leopardo da neve em razão da interferência humana nas montanhas do sul e do centro da Ásia. Esse animal solitário precisa de grandes espaços para suas faixas, mas, devido às mudanças climáticas e à taxa relativamente mais rápida de aquecimento global nas cadeias montanhosas do sul da Ásia, seu hábitat vai encolher e fragmentar-se por mudanças nas linhas de árvores e na hidrologia da área. Este artigo teve o objetivo de rever vários estudos sobre os impactos das mudanças climáticas em um futuro próximo e distante sobre os hábitats do leopardo-da-neve. O estudo revelou que a modificação vegetativa da flora da montanha e a competição com cabras domésticas poderiam ocasionar na diminuição da população de suas presas, com a chance de um conflito direto e competição com leopardo comum. Leopardo comum sendo mais adaptável, agrupado e maior em tamanho pode ser um estressor significativo para um leopardo-da-neve menor e solitário. Conclusão: devido ao encolhimento do hábitat, o leopardo-da-neve pode, possivelmente, mover-se para cima ou para o norte, para faixas da Ásia Central com padrões migratórios não previstos.

Common leopard being more adaptable, grouped, and larger in size can be a significant stressor for a smaller and solitary snow leopard. Habitat would shrink, and snow leopard can possibly move upslope or northward to central Asian ranges and their predicted migratory patterns are unknown.

O leopardo-das-neves (Panthera uncia) é um felídeo que vive nas áreas altamente acidentadas das regiões alpinas, em diferentes cadeias de montanhas do sul e do centro da Ásia. A revisão atual tem o objetivo de abordar a questão da possível perda de hábitat do leopardo da neve em razão da interferência humana nas montanhas do sul e do centro da Ásia. Esse animal solitário precisa de grandes espaços para suas faixas, mas, devido às mudanças climáticas e à taxa relativamente mais rápida de aquecimento global nas cadeias montanhosas do sul da Ásia, seu hábitat vai encolher e fragmentar-se por mudanças nas linhas de árvores e na hidrologia da área. Este artigo teve o objetivo de rever vários estudos sobre os impactos das mudanças climáticas em um futuro próximo e distante sobre os hábitats do leopardo-da-neve. O estudo revelou que a modificação vegetativa da flora da montanha e a competição com cabras domésticas poderiam ocasionar na diminuição da população de suas presas, com a chance de um conflito direto e competição com leopardo comum. Leopardo comum sendo mais adaptável, agrupado e maior em tamanho pode ser um estressor significativo para um leopardo-da-neve menor e solitário. Conclusão: devido ao encolhimento do hábitat, o leopardo-da-neve pode, possivelmente, mover-se para cima ou para o norte, para faixas da Ásia Central com padrões migratórios não previstos.

Unique position of a pancreatic head insulinoma during laparoscopic enucleation: case report

Insulinomas are benign pancreatic neuroendocrine tumors that require surgical intervention as a therapeutic measure. We describe an 18-year-old male patient who presented to the emergency department with a history of syncope, blurred vision, and diaphoresis. His blood sugar level was low upon admission, and a 72-hour fasting plasma glucose test showed low serum glucose, high serum insulin, and high C-peptide. An abdominal computed tomography scan and magnetic resonant imaging revealed a solitary tumor in the pancreatic head with no sign of ductal dilatation. Laparoscopic enucleation was performed, and a histopathological examination revealed findings consistent with insulinoma. The patient’s postoperative course was uneventful, and his follow-up examination was unremarkable. In conclusion, physicians should have a high clinical suspicion index for insulinomas, especially in young patients with a history of syncope, blurred vision, and diaphoresis, in order to avoid delayed diagnosis.

Effect of Antiasthma Medication on Blood Eosinophil Count and Serum Immunoglobulin E Levels: A Randomized Controlled Study

Background:Asthma is a chronic inflammatory condition of lung airways resulting in episodic airflow obstruction. Aims: The main objective of this study is tofind the effect of antiasthma medication on serum IgE levels and blood eosinophil count.Study Design:Thisrandomizedcontrolled trial studywas performed in children aged 6-15 years of age, with clinically stable and moderate persistent asthma.Results:The findings of this study indicate both group(Budesonide/formoterol group and budesonide group) patients experienced a significant decrease in serum IgE levels and blood eosinophil counts over the study period.However, the difference in two groups was not statistically significant.Conclusions:Inhaled steroids are effective in controlling systemic inflammation in asthma as evidenced by a decrease in IgE levels and eosinophil counts. However addition of LABA doesn’t have any additive effect.

Perioperative glycemic control and its outcome in patients following open heart surgery

Background: Diabetes is not uncommon in patients requiring cardiac surgery. These patients have a higher incidence of morbidity and mortality. Subsequently, diabetes represents a major medico-economic problem in both developed and developing countries. This study was designed to observe the association between glycemic control and outcome of patients after open heart surgery in adult population. Materials and Methods: Data was collected retrospectively in all patients who underwent open cardiac surgery (coronary artery bypass grafting, valve, or bypass grafting with valve surgery) and survived 72 hours postoperatively and had diabetes. The study was conducted from January 2015 to December 2016. Results: Of the 129 patients included in the study, male dominated 101 (78.3%). Most frequent surgery was coronary artery bypass grafting (CABG) 123 (95.3%), CABG plus aortic valve replacement 4 (3.1%), and CABG plus mitral valve replacement 2 (1.6%). Considering diabetes, only 3 (2.3%) were on diet control, 112 (86.8%) on oral hypoglycemic agents (OHA), whereas 9 (7%) had control on both insulin and OHA. Only 5 (3.9%) had type I diabetes. The mean fasting blood sugar (FBS) was 154.58 g/dl, and the mean duration of diabetic mellitus was observed 12.32 years. Microvascular and macrovascular complications were 26/129 (20.16%) and 17/129 (13.17%), respectively. Total 75 (58.1%) patients did not require insulin and 54 (41.9%) were treated with insulin intraoperatively to keep the blood glucose level less than 200 g/dl. Cardiac arrhythmias were frequent in the insulin group (P < 0.05), which was also associated with increased stay in the cardiac intensive care unit. Conclusion: Inadequate glycemic control during open cardiac surgery can possibly lead to increased perioperative morbidity and mortality and with decreased long-term survival and recurrent ischemic events. Therefore, aiming for blood glucose levels around 140 mg/dl appears reasonable. Further studies are required to define specific glucose ranges for a clearer definition of recommended blood glucose goals in postoperative cardiac patients for the best outcomes in patients with diabetes mellitus.

Evaluation of the Interventional Approaches in the Management of Cutaneous Leishmaniasis in Jazan: An Observational Study

BACKGROUND: Cutaneous leishmaniasis is a tropical infection of public health importance. Numerous treatment approaches are in practice with variable degree of success however its management has no universal consensus or practice guidelines to follow. OBJECTIVE: Analyze the management of cutaneous leishmaniasis retrospectively at a central hospital of Jazan Province, Kingdom of Saudi Arabia to identify the current treatment pattern and compare the outcomes. METHODS: This cross-sectional study was conducted based on the hospital records of patients who attended the dermatology clinic for cutaneous leishmaniasis during the year 2012 to 2015. RESULTS: Forty three patients were included in the study. There was a male preponderance (65.1%) among the patients and 60.5% of them were of pediatric age group. Monotherapy was the initial choice for 58.1% of the patients. Intralesional sodium stibogluconate (SS-IL) was the most preferred treatment for initial therapy, as monotherapy and as part of combination therapy. A complete response was achieved in 22 patients (51.2%) with initial therapy. Among the different treatment groups, SS-IL+itraconazole showed significantly higher complete response rate compared to other treatments offered as initial therapy (p<0.01). Initial SS-IL monotherapy provided complete response in 41.2% patients receiving it, while itraconazole monotherapy provided complete response in 75% and 90.9% of the patients receiving initial itraconazole+SS-IL combination therapy with achieved complete response. CONCLUSION: The findings and observations suggest that initial combination therapy with SS-IL+itraconazole significantly improved the complete response rates and thus reduced the need for additional or prolonged therapies.

Dentistry as a career: Factors and Motivational Reasons – A Comparative questionnaire study of Students of Public and Private Schools in Saudi Arabia

Background: Many studies have been done to find out the motivational factors in choosing dentistry as a career. Only few studies are carried in middle East countries like Saudi Arabia. Aims and Objectives: To establish the motivational factors behind selecting a career in dentistry by students of both gender in public and private schools in Saudi Arabia. Materials and Methods: An anonymous questionnaire was distributed to 398 students of both public and private dental schools in Saudi Arabia. Candidates were asked to score the influence of certain factors on their decision to choose dentistry as a career on a scale from 0 to 10 in order of increasing importance. The obtained data was statistically analysed by graph pad prism software. Results: Comparison between males and females for the parameter which year of study showed that there was no significant difference (P=0.180). But there was a significant difference between public and private school for the parameter which year the students studied (P=0.030). There was significant difference between male and female for the parameter one or more of my relatives are dentist (P<0.05).

Prepubertal and postpubertal vitiligo: a multivariate comparative study in 375 patients

Abstract: Background: The onset of vitiligo during childhood is common. Limited data exist that compare the clinical associations of prepubertal and postpubertal vitiligo in Arabs. Objective: To compare the clinical profile of pre and postpubertal onset vitiligo. Methods: A cross-sectional observational study was conducted. The Vitiligo European Task Force questionnaire was completed for each patient. Results: A total of 375 patients were included; 199 had postpubertal vitiligo (>12 years), and 176 had prepubertal onset vitiligo (<12years). There were more females in the prepubertal group (49%) than in the postpubertal group (29%), p-value <0.001. The prepubertal group has had more involvement than the postpubertal group (45% vs 30%, p=0.004). Only 8 cases of segmental vitiligo were observed; five were observed in the prepubertal group of patients. Female gender (OR=2.3; 95% CI:1.5, 3.5), presence of halo nevus (OR=2.2; 95% CI:1.1, 4.4) and face involvement (OR=1.9; 95% CI:1.2, 2.9) were positively associated with prepubertal vitiligo. Stress, as an onset factor, was positively associated (OR=0.51; 95% CI:0.3, 0.8) with postpubertal onset vitiligo. Study limitations: A possible selection bias toward more severe vitiligo cases can be a limitation, because the study was conducted in a clinic specialized in vitiligo. Moreover, a likelihood of false recall bias cannot be excluded. Conclusions: Our data present clinical evidence that vitiligo behaves mostly the same way in the prepubertal group as in the postpubertal group. However, female over-representation, more face involvement and more halo nevi were observed in prepubertal vitiligo, while stress was more prevalent as an aggravating factor in postpubertal vitiligo patients.

An accessory extensor pollicis longus tendon: a case report of rare anatomical variant / Tendón accesorio del músculo extensor largo del pulgar: reporte de caso de una rara variación anatómica

SUMMARY: Variation in the morphology of the extensor pollicis longus muscle is very rare. The muscle is considered as one of the deep group of dorsal forearm muscles. It passes through the dorsal radiocarpal ligament in a detached compartment. It inserts at the base of the distal phalanx of the thumb. The muscle might have double tendons where they run either in one, or in separate compartments. In this study, we report an extremely rare condition for a 38-year-old male where some of the tendon fibers split at the base of the proximal phalanx and the two tendons insert at the sides of the base of the distal phalanx. We also noticed a high range of hyperextension where the action was painless and showed no sign of discomfort. We believe that the way the tendons get inserted might have a role in this wide range of extension.

RESUMEN: La variación en la morfología del músculo extensor largo del pulgar es muy rara. Es considerado perteneciente al grupo profundo de los músculos del dorso del antebrazo. Su tendón pasa a través del ligamento radiocarpiano dorsal en un compartimiento separado. Se inserta en la base de la falange distal del pulgar. El músculo puede tener tendones dobles que pasan a través de un solo compartimiento, o en compartimentos separados, del ligamento radiocarpiano dorsal. En este estudio se reporta una variación extremadamente rara en un hombre de 38 años de edad, donde algunas de las fibras del tendón se dividen en la base de la falange proximal y los dos tendones se insertaban a los lados de la base de la falange distal del pulgar. También observamos un alto grado de hiperextensión siendo la acción indolora y no mostrando ningún signo de malestar. Creemos que la forma en que los tendones se insertan podrían tener un papel en este amplio rango de extensión.

Vascular sclerosing effects of bleomycin on cutaneous veins: a pharmacopathologic study on experimental animals

Abstract: Background: Varicose veins and the complications of venous disease are common disorders in humans. Objective: To study the effects of bleomycin as a potential new sclerosing agent and its adverse events in treating varicose veins. Methods: Bleomycin-loaded liposomes 0.1ml was injected in the dorsal ear veins of white New Zealand rabbits. Sodium tetradecyl sulfate was used as a positive control. Normal saline was used as negative control. The blood vessels of the treated ears were photographed before and at one hour and two, eight and 45 days after treatment. Biopsies from the treated areas were obtained for histological examination. Blood samples were collected to determine any possible toxicity. Results: Bleomycin by itself was ineffective; therefore, liposomes were used as a vector to deliver bleomycin to the vein lumen. Subsequently, bleomycin started showing its sclerosing effects. Toxicity monitoring showed no apparent hematologic, pulmonary, hepatic or renal toxicities. This study revealed that bleomycin induced vasculitis, which led to vascular occlusion, which was observed on day 1 and day 8. No bleomycin-related injury was noted by histopathological examination of lung sections. The calculation of the lung/body weight coefficient indicated that edema was present in the experimental groups compared with the negative and positive controls. Study limitations: Relatively small number of experimental animals used. Conclusions: This study showed that bleomycin-loaded liposomes were able to induce vasculitis and vascular occlusion without any toxicity or complications. It might be useful, hence, to treat patients suffering from Varicose veins and other ectatic vascular diseases with this agent.
