Blood component therapy is a very common intervention practiced in newborns; nearly 85% of extremely low birth weight (ELBW)
babies get transfusions during their hospital stay. However, there are no set guidelines for transfusion of blood component
therapy in newborns. This protocol includes available types of blood components, their methods of preparation, indications
and side effects of transfusion, in relation to newborns. 相似文献

Transient myeloproliferative disorder (TMD) in newborns with Down syndrome (DS) has been well described. We report 4 newborns, 2 with DS and 2 without DS, who developed TMD. One newborn with DS developed multiorgan failure and died despite treatment with low-dose cytarabine. In 3 newborns, the TMD resolved spontaneously. Two of these patients, 1 with and 1 without DS developed leukemia on subsequent follow-up and were treated successfully. We reviewed the clinical and laboratory data on 14 non-DS infants with TMD reported in the literature. According to limited data, these patients are more likely to develop leukemia than DS patients, however their outcome is better. 相似文献

Ever since its inception, acrodermatitis continua of Hallopeau, has been recognized as an uncommon clinical entity which has been sparingly reported from across the globe. The attempt to have cumulative information on prevalent nomenclature, definition, reminiscences, and clinical overtures has brought differential diagnosis and diagnosis in sharp focus, the highlights of which are outlined. Hence, it was considered important to review the evolution of treatment options available thus far including use of biologics. 相似文献

Psoriasis is a chronic, relapsing, cutaneous condition with 1-2% prevalence in the general population. There are many factors involved in the induction and/or exacerbation of psoriasis of which stress is a well-known trigger factor in the appearance or exacerbation of psoriasis. Stress reaction in patients with psoriasis is probably mediated by the hypothalamic-pituitary-adrenal relationship with immunologic effects. Stress response involves increased levels of neuroendocrine hormones and autonomic neurotransmitters. Psychological stress or an abnormal response to stressors has been found to modify the evolution of skin disorders such as psoriasis. It can also have substantial psychological, and psychosocial impact on a patient's quality of life. Treatment regimens include stress-reduction strategies, such as biofeedback, meditation, yoga, and self-help approaches. This review focuses the relationship between psoriasis and stress, especially relating to psychosocial, psychological, and emotional stress aspects. 相似文献
