Juvenile diabetes: Impact on the child and family

The work of a child psychiatrist and a social worker with a group of adolescent juvenile diabetics is described. The conceptual framework that emerged from this experience draws on developmental and psychodynamic theory that may be applied to other chronic disease patients. The authors provide recommendations for the practical application of the model for pediatricians and describe the acceptance of the diagnosis as akin to the mourning process.     

Urinary catabolites of ribonucleic acid as cancer markers: a preliminary report of their use in patients with lung cancer

Rats with aflatoxin-B1-induced hepatomas and dimethylnitrosamine-induced nephroblastomas excreted greater than normal amounts of urinary modified nucleosides and bases, catabolites of ribonucleic acid (RNA). Although both neoplasms caused increased excretions of the same catabolites, their quantitative profiles differed, suggesting that it may be possible to distinguish between tumors. Rats with transplanted tumors (e.g., hepatomas and osteogenic sarcomas) did not excrete elevated levels of urinary RNA catabolites until approximately 20 days after transplantation despite rapid growth of the tumor for the first 15 days. These data suggest that the source of the elevated levels of these excretory products may be the host's tissue RNA. Preliminary studies in human beings with lung cancer showed marked elevation of one or more urinary RNA catabolites. Resection of the diseased tissue in 2 patients caused a drop in levels. The measurement of urinary RNA catabolites may be useful in the diagnosis, prognosis, and evaluation of therapy in patients with lung cancer.     

Association of Target Volume Margins With Locoregional Control and Acute Toxicities for Non-small cell lung cancer Treated With Concurrent Chemoradiation Therapy

Purpose

This study aimed to investigate the association between target volume margins and clinical outcomes for patients with inoperable non-small cell lung cancer (NSCLC) treated with concurrent chemoradiation therapy.

Hypersensitivity reaction to a metabolite of cyclophosphamide

Generalized urticaria and fever were noted in a patient with IgA (kappa) myeloma after intravenous cyclophosphamide. Intradermal skin testing revealed no reaction to cyclophosphamide and its analog, isophosphamide. However, phosphoramide mustard, a principle metabolite of cyclophosphamide, evoked an immediate wheal-and-flare response. Subsequent therapy with isophosphamide was well tolerated. These findings suggest that acute hypersensitivity reactions to cyclophosphamide are due to its metabolites and can be delineated with skin testing.     

Neuroleptic malignant syndrome

This article reviews the pathophysiology of neuroleptic malignant syndrome, including characteristics of the population most at risk, clinical precautions to take against its occurrence or rapid development, and the specifics of treatment with bromocriptine or dantrolene. Emphasis is placed on the need for prompt differential diagnosis and treatment of this sporadic but severe reaction to intake of neuroleptics or to withdrawal of indirect dopaminergic agonists, such as antiparkinsonism agents. Without such immediate recognition of the problem, the prospects of pennanent disability, coma, or death are high.     

External Iliac Artery Dissection During Renal Transplantation: A Case Report and Literature Review

Iliac artery dissection in the setting of renal transplant is a rare but potentially catastrophic event that may result in loss of kidney and lower extremity perfusion. We report a right external iliac artery dissection in a 45-year-old man with end-stage renal disease, diabetes, and hypertension who underwent a renal transplant at our institution. An external iliac artery dissection was diagnosed intraoperatively after completion of the arterial anastomosis given the mottled appearance of the kidney and loss of Doppler signal. The dissection was repaired via open endarterectomy, intimal tacking, bovine patching, and re-anastomosis of the kidney to a proximal site on the external iliac artery. To date, 23 cases of transplant-related iliac artery dissection have been described in the literature. Predisposing risk factors include atherosclerosis and hypertension combined with trauma from vascular clamps or suturing. There is a slight male predominance. Only one group utilized an open endarterectomy approach similar to ours, whereas others used synthetic vascular grafts (12 of 23), endovascular stents (4 of 23), donor iliac artery grafts (4 of 23), or saphenous vein grafts (2 of 23). In the absence of long-term outcomes data, the optimal repair mechanism is yet to be established.
