In-111-labeled liposomes: dosimetry and tumor depiction

Neutral phospholipid vesicles (liposomes) were loaded with 0.5 mCi (18.5 MBq) indium-111 and administered to 24 patients with various types of cancer. The median diameter of the liposomes was 77 nm, and lipid dose was 0.78-6.25 mg/kg. Scans obtained 24 and 48 hours after injection of In-111 liposomes showed gradual blood clearance with homogeneous uptake in the normal liver and spleen. Dosimetric estimates for these organs were 2.3 +/- 1.1 and 2.3 +/- 1.4 rad (.02 +/- .01 Gy), respectively, with a whole-body estimate of 0.28 rad (.003 Gy). Radiation dose did not correlate with lipid dose. Total renal excretion of In-111 was less than 2% of the injected dose in all but two patients. Transient eosinophilia occurred in two patients. Tumor was seen in the scans of 22 of 24 patients (unbinded readings). In-111-labeled liposomes may enable the demonstration of suspected or unsuspected sites of tumor.

L -粘附素单抗在缺血再灌注损伤中的作用

目的中性粒细胞粘附在缺血再灌注损伤中有非常重要的作用.本文用SD大鼠趾长屈肌缺血再灌注损伤模型,观察L-粘附素单抗LAM1-116在缺血再灌注损伤中的作用.方法30只SD大鼠被均分为2组LAM1-116组和生理盐水对照组.每只大鼠的一侧趾长屈肌作为正常对照,另外一侧进行3 h缺血4 h再灌注.结果LAM1-116组实验侧的髓过氧化物酶为正常的2倍(2.3±2.2),生理盐水对照组则为正常的28倍(27.5±11.7)(P＜0.001);LAM1-116组的湿重比(1.10±0.10)、疲劳肌力(77.1%±12.1%)与对照组相比(分别为1.23±0.10和49.7%±9.3%)明显改善(P＜0.05);组织学上,LAM 1-116组的中性粒细胞局部浸润显著减少,水肿减轻.结论通过L-粘附索单克隆抗体LAM1-116阻断L-粘附素的功能,可以有效地降低中性粒细胞在再灌注肌肉中的浸润,防止组织水肿,从而改善肌肉的功能.     

High Incidence of Sudden Death with Conduction System and Myocardial Disease Due to Lamins A and C Gene Mutation

BÉCANE, H.–M., et al. : High Incidence of Sudden Death with Conduction System and Myocardial Disease Due to Lamins A and C Gene Mutation. We studied 54 living relatives from a large French kindred, among which 17 members presented with a cardiomyopathy transmitted on an autosomal dominant mode. Five of these individuals had clinical manifestations of muscle disease phenotypically consistent with Emery-Dreifuss muscular dystrophy. Genetic analysis of this kindred had demonstrated a nonsense mutation in the LMNA gene located on chromosome 1q11–q23. This gene encodes lamins A and C, proteins of the nuclear lamina located on the inner face of the nuclear envelope. We retrospectively determined the cause of death of 15 deceased family members, 8 of whom had died suddenly, 2 as a first and single manifestation of the disease. The six other cases had histories of arrhythmias and left ventricular dysfunction before dying suddenly, and three of them died despite the prior implantation of a permanent pacemaker. The mean age of onset of cardiac symptoms among affected living family members was 33 years (range 15–47 years), and the first symptoms were due to marked atrioventricular conduction defects or sinus dysfunction, requiring the implantation of permanent pacemakers in seven cases. Myocardial dysfunction accompanied by ventricular arrhythmias developed rapidly in the course of the disease and resulted in severe dilated cardiomyopathy requiring cardiac transplantation in three cases. In conclusion, in patients presenting a life-threatening familial or sporadic cardiac restricted phenotype similar to that described here, mutations in the lamins A and C gene should be looked for. In the genotypically affected individuals, cardiological and electrophysiological follow-up should be performed to prevent sudden death that could occur rapidly in the evolution of such disease.     

The 'dry-needle technique': intramuscular stimulation in tension-type headache

The 'dry-needle technique', an intramuscular stimulation technique carried out by using a fine solid, 1-inch long, 30-gauge needle, was investigated in the treatment of tension-type headache (TTH) in a randomized, placebo-controlled trial. Fifteen patients with TTH received intramuscular needle insertions into six designated trigger points, while 15 controls received subcutaneous insertions. Headache indices, muscle tenderness and neck ROMs were evaluated before and after treatment. Mean headache indices improved significantly after treatment, both in the treatment group and in the placebo group, but the difference between the two groups was insignificant. In the treatment group the tenderness score and the neck ROM limitation score were significantly improved after treatment, while there was no significant improvement in the placebo group. We conclude that more and larger controlled, comparative trials are needed to show whether the dry-needle technique is an effective non-pharmacological alternative for the treatment of TTH.

Does cancer survivors' health‐related quality of life depend on cancer type? Findings from a large French national sample 2 years after cancer diagnosis

LE CORROLLER‐SORIANO A.‐G., BOUHNIK A.‐D., PREAU M., MALAVOLTI L., JULIAN‐REYNIER C., AUQUIER P. & MOATTI J.‐P. (2011) European Journal of Cancer Care 20 , 132–140
Does cancer survivors' health‐related quality of life depend on cancer type? Findings from a large French national sample 2 years after cancer diagnosis We investigated whether health‐related quality of life (HRQL) depends on cancer type, after adjustment for demographic and medical variables. A French national population‐based survey was conducted between November and December 2004 to assess surviving cancer patients' HRQL 2 years after diagnosis. HRQL was measured by the 36‐Item Short Form Survey scale. The sample included 3900 persons. All cancer diagnoses were entered in the study. We demonstrated that medical and treatment variables have an impact on patients' physical HRQL but not on mental HRQL. Cancer type impacted on physical HRQL, with those suffering from upper aerodigestive tract /lung cancers and haematological malignancies being affected to a greater degree. Disturbing side effects impacted both HRQL domains. Socio‐demographic variables had statistically significant effects but not clinically meaningful ones. Socio‐economic variables led to potentially clinically meaningful differences for cancer patients' HRQL and represented a socio‐economic gradient in HRQL among cancer survivors. From our results, we may assert that cancer survivors, 2 years after cancer diagnosis, share a similar pattern of psychological morbidity, independent of cancer type. Patients disproportionately affected by cancer, such as those with lower educational levels and income, need to be identified and targeted and interventions which address their unique needs and concerns need to be developed.
