Tofacitinib is an immunosuppressive and disease-modifying therapy in rheumatoid arthritis. It may result in many infections flaring up. It is important to take precautions of all kinds (cardiovascular, malignancy, infections etc.) before starting tofacitinib. In this article, we have highlighted important steps where we need to take precautions before starting tofacitinib.  相似文献

Intracranial Angioplasty and Stenting in the Awake Patient   总被引:1,自引:0,他引:1  
BACKGROUND AND PURPOSE: Endovascular treatment for intracranial atherosclerosis is evolving, but complications remain an issue. Most interventions are performed under general anesthesia, preventing intraprocedural clinical evaluations. We describe our approach to intracranial angioplasty and stenting, using local rather than general anesthesia, and intraprocedural neurological assessment. METHODS: We prospectively collected procedural and outcome information on all patients undergoing intracranial angioplasty and stenting. Patients underwent interventions under local anesthesia with mild intravenous sedation or analgesia only if needed. Intraoperative neurological evaluations were performed, and symptomatology was used to guide the interventional technique. RESULTS: Forty-eight arteries in 40 patients with a mean age of 65.2 years were treated. Thirty-two anterior and 16 posterior circulation segments were treated. Technical success was achieved in 100% of patients with reduction of the mean pretreatment stenosis from 85 +/- 8.6% to 7 +/- 10.1%. Stents were deployed in 40 segments; five patients were treated with drug-eluting stents. The cobalt-chromium coronary stents were the easiest to deliver. Thirty-seven patients were treated under local anesthesia and, of those, 61.4% experienced intraprocedural symptoms that led to some alteration of the interventional technique. Headache was the most common symptom, and, when persistent, it heralded the occurrence of subarachnoid hemorrhage. There were seven total neurological complications, but only five (10.5%) led to permanent morbidity (4 strokes) or mortality (1 death). CONCLUSIONS: Intracranial angioplasty and stenting can be successfully performed using coronary techniques and equipment including drug-eluting stents. Local anesthesia permits neurological evaluations and often leads to the adjustment of the interventional technique, potentially making the procedure safer.  相似文献

The infant is the youngest but perhaps the most valuable member of society. It has been unequivocally established through research that the period up to two years is the most potent for forming and establishing the basis of later development. This paper summarizes the findings of two research studies on infant care in India that began in July 1988 and culminated in March 1989 under my guidance. The two studies are linked in their final implications for infant stimulation and in their role in providing insights into changing trends in infant-care in India.

In study I patterns of infant caregiving practiced by fathers were investigated. Study II looked into infant-care practices in Punjabi families where the grandmother lived with the young parents.  相似文献

慢性胰腺炎的临床表现包括疼痛、脂肪泻和糖尿病。在西方国家,慢性胰腺炎最常见的病因是酗酒。70%以上的病人在就诊时有疼痛的临床表现,而且,这些患者中又有75%以上会在几年之后出现疼痛减轻或完全消失。对于所有的慢性胰腺炎的病人来说,均应排除非胰源性疼痛和胆道梗阻、胰腺假性囊肿等胰腺局部并发症。应建议所有慢性胰腺炎病人戒烟、戒酒。阿片类镇痛剂仅应用于治疗疼痛严重的病人。尽管有报道认为胰酶替代治疗有助于止痛,但是,对于已经确诊的慢性胰腺炎病人来说,该疗法无效。激素类药物进行腹腔神经丛阻滞术可能有助于病人度过剧烈疼痛期。顽固性疼痛是进行胰液引流或胰腺切除的适应证。建议应用适量胰酶替代联合(或不联合)制酸剂治疗营养不良。慢性胰腺炎导致的糖尿病与原发性糖尿病的治疗原则相似。  相似文献
