Parents and children in art

It is an honour to have been asked to contribute to this volume that commemorates the life and work of Spyros Doxiadis. Spyros was, and is still, a vital and stimulating influence on those of us who were fortunate enough to have been his colleague in all phases of his life. My period of closeness to him was when he was working in Sheffield with Ronald Illingworth. At that time (now over 40 years ago) he and Katherine were having their children and my wife and I was having ours. Then words like "bonding" had not become commonplace as today, but the functional patterns of family relationships were something about which we were intensely aware. I particularly remember a summer when we were holidaying on a tidal estuary between Anglesey and Holy Island and recall a moment when Spyros and I were sitting on a grass topped sandbank watching our children and wives at the water's edge "messing around" with a boat. We watched and discussed the beauty of the postures and poses of our womenfolk with the children and the children with each other. It was the memory of that conversation that stimulated me to propose the topic of this essay in Spyros' memory.     

Effects of growth hormone therapy in prepubertal children with short stature secondary to intrauterine growth retardation

A total of 130 short children were included in a French multicentre study and randomized between a control group (group A) and two groups treated with daily subcutaneous injections of GH at doses of 0.7 IU/kg/week (group B) and 1.4 IU/kg/week (group C) for 2 years. Height velocity was significantly increased ( p <0.0005) in groups B and C, with a greater increase in group C than in group B ( p < 0.001). The benefit after 2 years compared with controls was 4.3 cm in group B and 5.9 cm in group C. The rate of bone maturation was not affected by GH therapy. These results led to the conclusion that 2 years of treatment with GH improves final height prognosis in children with short stature secondary to IUGR, and that this effect is dose dependent. The effect on final height has still to be demonstrated.     

Colorectal hemangioma: radiologic findings

The authors correlated radiographs with the clinical and histologic data of 12 patients with colorectal hemangioma. All patients presented with rectal bleeding, which was chronic in seven. Phleboliths were also visible in seven cases, which correlated with chronic bleeding in five. On barium studies, three masses were soft and three produced rigid narrowing. The atypical features of rigid luminal narrowing, which might mimic a carcinoma, and hypovascularity correlated with chronic bleeding or visible phleboliths, which suggest the correct diagnosis of colorectal hemangioma.     

汉族志愿者阿米替林代谢与异喹呱羟化代谢的关系

8名男性健康志愿者po阿米替林100 mg后,以阿米替林及其3种代谢物的血浓度曲线下面积(AUC₀^∞)计算阿米替林的脱甲基化代谢及羟基化代谢能力。结果提示个体间阿米替林及其3种代谢物的AUC差异很大。其中7名志愿者测定异喹呱羟化代谢表型,6例为异喹呱强代谢者,1例为弱代谢者。尿中异喹呱的羟化代谢率与阿米替林的羟基化代谢率、阿米替林和10-羟基阿米替林的AUC₀^∞呈显著相关。阿米替林总血浆清除率与异喹呱羟化代谢率呈弱相关。此结果表明阿米替林和异喹呱的羟化代谢可能由同一酶控制,阿米替林的羟基化代谢和脱甲基化代谢可能为两个独立的代谢途径。     

Failure of ablation of a mediastinal parathyroid adenoma by repeated contrast staining

In a patient with primary hyperparathyroidism an attempt was made to ablate a middle mediastinal parathyroid gland by forceful staining with radiographic contrast material. The gland was stained on two separate occasions, two weeks apart. Both times the serum calcium level temporarily fell to the normal range but reverted to abnormal levels. The patient ultimately required surgery for correction of hypercalcemia. The mechanism of staining and possible reasons for failure as well as potential complications are discussed.     

Emphysema in the renal allograft

Two diabetic patients in whom emphysematous pyelonephritis developed after renal transplantation are described. Clinical recognition of this unusual and serious infection is masked by the effects of immunosuppression. Abdominal radiographic, ultrasound, and computed tomography findings are discussed. The clinical presentation includes urinary tract infection, sepsis, and acute tubular malfunction of the allograft in insulin-dependent diabetics.
