The use of group sessions for the emotional support of families of terminal patients

Abstract

To meet the need for emotional support for family members of terminal patients, a weekly group session was established on a cancer unit. The group has allowed family members to share their fears, concerns, and doubts as well as receive support from other individuals experiencing similar traumatic situations. The development and goals of this group are discussed.     

Human acute leukemia cell line with the t(4;11) chromosomal rearrangement exhibits B lineage and monocytic characteristics

A cell line, designated RS4;11, was established from the bone marrow of a patient in relapse with an acute leukemia that was characterized by the t(4;11) chromosomal abnormality. The cell line and the patient's fresh leukemic cells both had the t(4;11)(q21;q23) and an isochromosome for the long arm of No. 7. Morphologically, all cells were lymphoid in appearance. Ultrastructurally and cytochemically, approximately 30% of the cells possessed myeloid features. The cells were strongly positive for terminal deoxynucleotidyl transferase. They were HLA-DR positive and expressed surface antigens characteristic for B lineage cells, including those detected by anti-B4, BA-1, BA-2, and PI153/3. Immunoglobulin gene analysis revealed rearrangements of the heavy chain and kappa chain genes. The cells lacked the common acute lymphoblastic leukemia antigen and antigenic markers characteristic of T lineage cells. The cells reacted with the myeloid antibody 1G10 but not with other myeloid monoclonal antibodies. Treatment with 12-O-tetradecanoyl- phorbol-13-acetate induced a monocyte-like phenotype demonstrated by cytochemical, functional, immunologic, and electron microscopic studies. The expression of markers of both early lymphoid and early myeloid cells represents an unusual phenotype and suggests that RS4;11 represents a cell with dual lineage capabilities. To our knowledge, RS4;11 is the first cell line established from t(4;11)-associated acute leukemia.     

锌酞菁脂质体光动力作用引起小鼠肿瘤的细胞程序性死亡

电镜观察了锌酞菁脂质体光动力作用引起小鼠ＭＳ－２纤维肉瘤的形态学变化。发现其作用很强，并对肿瘤细胞有明显的直接影响。肿瘤细胞的结构表现出明显的程序性细胞死亡（ａｐｏｐｔｏｓｉｓ，ｐｒｏｇｒａｍｍｅｄｃｅｌｄｅａｔｈ）的特点：胞核染色质凝聚边集、核固缩、核破裂、染色质凝块流失、胞质内吞噬现象、胞膜表面肿胀粗钝的胞突形成、细胞碎裂等。加深了对锌酞菁脂质体光敏作用机理的认识，但其详细的发生机制和调节途径有待阐明。     

Computer graphics for digitally formatted images

The increasing use of digitally formatted imaging systems requires high-quality interactive gray-scale computer raster graphics systems for the management, display, and analog film recording of digital image and alphanumeric information. These systems are a combination of computer hardware and software and implement a set of graphics protocols. This paper describes a set of interactive graphics protocols that has been developed for clinical use.     

Digital imaging of the chest

During the past several years, image acquisition in nuclear medicine, computed tomography, ultrasonography, subtraction angiography, and magnetic resonance has been by digitization. Despite these advances, research in the development of digital imaging in conventional radiography has lagged behind. Although studies with a variety of digital techniques have been carried out on several fronts, we still do not possess a method that has captured the imagination of the majority of radiologists and other physicians to a point where it could replace conventional screen-film imaging. This article reviews the current status and general principles of the technology, focusing on the four digital radiographic techniques that have shown the greatest promise - film digitization, an image intensifier - based system, photostimulable phosphor plates, and a scanned projection system. The physical aspects of each of the four systems and the clinical results that have been reported to date, as well as the advantages and disadvantages of each system, are presented.     

Retinal pigment epithelium tears following ranibizumab for exudative age-related macular degeneration

PURPOSE: To report two cases of retinal pigment epithelium (RPE) tears following intravitreous ranibizumab injection for age-related macular degeneration (AMD)-associated serous pigment epithelium detachment (PED). DESIGN: Noncomparative case series. METHODS: The charts of two patients who received intravitreous ranibizumab for AMD-associated PED and developed RPE tears were reviewed. Fundus photography, fluorescein angiography and optical coherence tomography performed prior to injection and upon follow-up confirmed the diagnosis. RESULTS: Two patients with serous PED and occult choroidal neovascularization associated with AMD developed RPE tears within four weeks of injection with ranibizumab. CONCLUSIONS: RPE tears may complicate ranibizumab intravitreous injection for the treatment of AMD-associated PEDs. Further studies need be undertaken to determine whether this complication may also occur when treating choroidal neovascular membranes not associated with PED and whether certain angiographic subtypes are more susceptible to this complication.     

Patientennutzen und Anwendungsmerkmale der Behandlung irritierter Haut mit dexpanthenolhaltiger Salbe

Background

Products containing dexpanthenol are used to treat irritated and inflamed skin. So far there is a lack of data for the evidence of patient-relevant benefits.

Objective

Assessment of the patient-relevant benefit of ointments containing dexpanthenol in the self-medicated therapy of irritated skin.

Methods

Prospective, observational study in a network of 392 pharmacies. Consecutive recruitment of n=1,886 patients with symptoms of irritated skin, including non-inflammatory intervals of atopic eczema, other xerotic skin conditions and impairment of skin barrier. The patient-relevant benefit was ascertained prior to and 7–10 days after treatment through the patient-benefit index (PBI).

Results

The PBI showed that 91.5% of the patients experienced a relevant benefit from treatment. 94.7% directly indicated to have had achieved successful therapeutic results. All symptoms of irritated skin (e.g. xerosis, erythema, desquamation) significantly improved (p≤0,001). The subjective response was independent of age, gender and underlying skin disease.

Conclusion

High patient-relevant benefits were observed in the treatment of irritated skin with dexpanthenol ointment.
