The Role of Iron Deficiency in Protein‐losing Enteropathy Following the Fontan Procedure

We describe the case of an adult who developed protein‐losing enteropathy 21 years after having undergone a Fontan procedure. Investigations revealed iron deficiency anemia which was treated with intravenous iron sucrose leading to resolution of both the anemia as well as symptoms of protein‐losing enteropathy.     

AIDS and anaesthesia

The Acquired Immune Deficiency Syndrome (AIDS) is a group of conditions which is reaching epidemic proportions. It is caused by a virus new to man, with an as yet poorly understood natural history, ominous prognosis and no known cure. Anaesthetists should be aware of the implications of dealing with increasing numbers of both diagnosed and undiagnosed AIDS patients and asymptomatic carriers in the fields of resuscitation, intensive therapy and theatre anaesthesia. The misunderstanding of AIDS is as extensive as the literature on the subject and a review of the current knowledge of the disease relevant to the anaesthetist is pertinent.     

LOW SERUM CARNITINE CONCENTRATIONS IN HEALTHY CHILDREN WITH IRON DEFICIENCY ANEMIA

Carnitine is not only obtained from animal-derived foods but also synthesized in the body. It plays an important role in the energy metabolism of many tissues, including heart and skeletal muscles. Iron is known to be essential for the biosynthesis of carnitine. Although many conditions are well known to cause secondary carnitine deficiency, iron deficiency, which is a very common condition in children, is not well studied as a cause of secondary carnitine deficiency in humans. This study demonstrates the coexistence of iron deficiency and low carnitine levels in otherwise healthy children. The mean carnitine concentration of 18 otherwise healthy children with iron deficiency anemia was significantly lower compared to the mean carnitine concentration of healthy children without iron deficiency anemia. Based on the evidence about the effect of low iron on carnitine stores in experimental animals, we proposed that low serum carnitine levels in these children may be secondary to iron deficiency. However, further studies need to be done to further clarify this relationship.     

广东地区学龄前儿童膳食结构与缺铁性贫血的关系

本文对广东地区城乡学龄前儿童的膳食营养状况进行了调查研究,结果表明膳食中钙、视黄醇和核黄素摄入量偏低,与1982年全国营养调查的结果一致,有28.9％受检儿童的血红蛋白含量低于11g/dI的标准,说明缺铁性贫血仍是当前学龄前儿童普遍存在的营养问题。将儿童的血红蛋白水平与膳食构成中各种因素进行多元线性回归分析,结果显示线性回归方程有显著性(复相关系数R=0.7088F=7.46,P<0.01),说明血红蛋白水平与膳食构成各种因素之间有线性相关,其中与可吸收铁量和总铁摄入量的相关最为密切(相关系数r分别为0.6176和0.5412,P<0.01)。提示通过改善膳食结构可以预防缺铁性贫血的发生。本文还调查分析了不同膳食水平幼儿园的膳食构成与贫血发生率的关系,并观察了进行膳食指导和改善膳食构成的效果。同时观察了用铁强化食品补充膳食中总铁摄入量防治缺铁性贫血的效果。     

7省自治区婴儿维生素K缺乏出血症的流行病学调查

目的 了解我国儿童维生素Ｋ缺乏出血症的发病和死亡情况。方法 对７省、自治区６市８县１９９６年１月～１９９７年１２月间３１６４９名婴儿进行维生素Ｋ缺乏性出血症发病和死亡的回顾调查，并采用１：２病例对照的研究方法筛选发病危险因素。结果 ７省自治区平均婴儿维生素Ｋ缺乏出血症发病率为２．４‰，病死率为３０．３％。母亲妊娠期服药、婴儿２周内患病（肝胆疾患、腹泻、肺炎等）为危险因素；生后使用维生素Ｋ与非母乳喂     

全民食盐加碘对儿童智力发育的影响

[目的]了解全民食盐加碘对碘缺乏病区出生儿童智商的影响。[方法]用联合型瑞文测验测定儿童智商(IQ)，调查分析社会-经济-文化因素对智力的影响，测定尿碘水平、盐碘含量和甲状腺肿大情况。[结果]实施全民食盐加碘21年后，儿童甲状腺肿大率由57．4％下降到2．5％，尿碘水平由24．9μg／克肌酐升至209．6μg／L；补碘后出生的儿童IQ均值非常显著地高于补碘前，智力低下的发生率明显低于补碘前出生儿；将社会-经济-文化因素与儿童的智商进行多元逐步回归分析，R^2=0．314。[结论]实施全民食盐加碘是促进儿童智力发育的重要因素。
