10对联体双胎分离术后的远期结果

背景／目的：从1978-2000年，有10对联体双胞胎成功接受了手术分离，结果14人存活。其中6对是因为他们的联体同胞死亡或濒临死亡而接受紧急分离手术。剩余的4对，每对至少一个同胞接受至少一次的急诊手术后，才接受联体分离手术。方法：对这一独特的队列进行包含6个项目的问卷调查。问题的设计是开放式的，为父母／家庭提供有关信息的最大机会。对每个家庭就相同的问题也进行了当面的问卷调查。医师询问了与身体健康和疾病相关的一些问题。而社会工作询问了与发育、教育、社会心理和家庭功能相关的问题。结果：前面提及的14人存活的双胞胎中，4人大学毕业，1人于1981年完成中学学业，剩余9人正在上学。14人在最初的手术后，还需要接受再次手术，尤其是需要矫正泌尿系统、畸形、神经外科和小儿外科的问题。结论：通过超声检查对联体双胎进行宫内诊断，可以使医师和胎儿父母在孕早期决定在终止妊娠时是进行双胎分离还是保全其中一个。这些病例报道通过描述14例手术存活的长期体格检查和心理学检查结果，为医师和父母在关键时刻做出决定提供了另外有助的依据。     

A clinical study of nasopharyngeal masses

Out of 36511 patients attending the ENT OHD of R. G,. Aur Medical Callege & Hospital. Kolkata, in one year 0.08% patients were found tuning naspharyngeal mass. 30 cases of nasopharyngeal mass were studied. The peak incidence of nasopharyngeal mass was in the age group between II to 20 years (40%). The incidence in males (73%) was more than females(27%). The maximum ineldence was found among students (74%). Commonest ntuopharyngeal nuns teas antrochoanal polyp (30%). Next commlon masses were adenoids (23%)Juvenile angwfibroma(20%) and nasophartngeal carcinoma (13%). Nasal obstruction was the main presenting symptom(83%) followed by epistaxis (40%).     

Adrenergic and dopaminergic control of the canine paw microcirculation

Basal isolated canine paw blood flow was equally distributed between arteriovenous anastomosis (AVA) and capillary circulations. Norepinephrine decreased AVA flow by 92% and capillary flow by 41%. Dopamine significantly reduced AVA flow by 94% compared to baseline with a 37% reduction in capillary flow. However, with alpha-adrenergic blockade dopamine decreased AVA flow 66% while capillary flow increased 42%. Isoproterenol increased capillary flow almost twofold and appeared to decrease AVA flow, although the latter was statistically insignificant. Differential effects of adrenergic and dopaminergic agonists on canine paw AVA and capillary blood flow suggest the existence of independent regulation of these components of the microcirculation.     

A rare complication from prostaglandin analogue therapy

This case describes a rare complication of prostaglandin analogue eye drops used for treatment of primary open angle glaucoma. Though increase in the number, size and pigmentation of eyelashes is well‐known, this case shows extensive hair growth in malar region, which can be unacceptable. This complication can be one of the causes of discontinuation of prostaglandin analogue therapy.
