Phenotypic variability of a distinct deletion in McLeod syndrome

The X‐linked McLeod neuroacanthocytosis syndrome strongly resembles Huntington's disease and has been reported in various countries world‐wide. Herein, we report two Chilean brothers with predominant psychiatric features at disease onset including schizophrenia‐like psychosis and obsessive compulsive disorder. Molecular genetic analysis revealed a small deletion in the XK gene (938‐942delCTCTA), which has been already described in a North American patient of Anglo‐Saxon descent and a Japanese family, presenting with seizures, muscle atrophy or chorea yet absence of psychiatric features. These findings argue against a founder effect and indicate a profound phenotypic variability associated with the 938‐942delCTCTA deletion. Our report supports the inclusion of McLeod syndrome in the differential diagnosis of Huntington's disease as well as acute psychosis in male subjects. © 2007 Movement Disorder Society     

Use of digital photography in the Case orthodontic clinic.

In 2002, the orthodontic clinic at Case Western Reserve University totally converted to digital photography. We want to share the learning curve during this transition with clinicians planning the same change. A system and a protocol were developed for this transition; they have been in use for over a year. This system allows the handling of digital cameras when there are more clinicians than cameras; it can be applied to various specialties or fields.     

Near fatal infection of a patient with a left ventricular assist device due to unrecognized fetal death.

We report on an unusual case of a young female patient who received an implantable LVAD after unsuccessful emergency coronary bypass surgery following acute myocardial infarction. After LVAD placement, it became evident that the patient had been pregnant. She had to undergo gynaecological surgery during mechanical support to remove the deceased fetus.     

Physiology of continuous blood flow in recipients of rotary cardiac assist devices.

The beating heart and the resultant pulse wave have been a symbol of life for centuries. The development history of roller pumps for cardiopulmonary bypass shows that the human body tolerates non-pulsatile blood flow, at least for short-term support. Over the last few years, many types of rotary blood pumps have been developed for clinical use in patients requiring mid- to long-term support. Although early clinical experiences in patients with long-term support have been promising, the matter of whether pulsatile flow is needed or not remains controversial. Therefore, this review summarizes the observed clinical consequences of continuous blood flow in patients supported by rotary blood pumps and relates these consequences to underlying experimental studies.     

An occupational perspective on the concept of participation in the International Classification of Functioning, Disability and Health--some critical remarks.

The International Classification of Functioning, Disability and Health (ICF; World Health Organization, 2001) provides an international and interprofessional scientific basis for understanding and studying health. The concept of participation plays an important role in the classification and has become a central construct in health care, rehabilitation, and in occupational therapy. The aim of this paper is to provide a critical analysis of the concept of participation in the ICF. As background, the origins and current presentation of the ICF are presented. The use and function of the ICF and the contemporary discussions regarding the classification are reviewed. An occupational perspective on participation in the ICF reveals major shortcomings regarding the subjective experience of meaning and autonomy. Furthermore, the ICF has limitations in capturing different kinds of participation in a single life situation. Following these analyses we discuss the advantages and shortcomings of using the ICF, and how an occupational perspective can contribute to an ongoing discussion about the development of the ICF.     

Results of pulmonary resection for lung cancer in Norway, patients older than 70 years.

OBJECTIVE: Surgical resection for lung cancer is the mainstay of curative treatment, but studies regarding postoperative results and long term outcome in the elderly have differed. The purpose of the present study was to assess the early and long-term results of surgical resection in patients more than 70 years of age. METHODS: In Norway all clinical and pathologic departments submit reports on cancer patients to the Cancer Registry of Norway. This investigation included all patients more than 70 years of age resected for lung cancer in the time period 1993-2000. For results of long-time follow-up only patients operated on between 1993 and 1998 were included. RESULTS: A total of 763 patients (541 men) were identified aged 71-87 years. Postoperative mortality rate was 9%, highest after bilobectomy and pneumonectomy. The most commonly reported causes of postoperative death were pneumonia and cardiac complications. The majority of patients had tumor categorized as clinical stage (cStage) Ia and Ib. More than 100 in each of these groups proved to have more advanced disease postoperatively (pStage). The 5-year relative survival rate was significantly better in patients with disease in pStage I compared to higher stages. Women had a significantly better 5-year survival rate compared to men, 62.8 and 35.7%, respectively. CONCLUSIONS: Lung cancer surgery appears to be a relatively safe procedure even in the elderly. There is a high postoperative mortality after bilobectomy and pneumonectomy. However, when old people survive the postoperative period the long term prognosis seems favorable.     

Expressed-emotion development and course of schizophrenic illness: considerations based on results of a CFI replication

This study examines the correlation between development of expressed emotion (EE) in relatives and course of illness of 99 DSM-III schizophrenic patients. Patients whose relatives were high EE at baseline and at the 2nd CFI approximately 20 months later had a poor prognosis at the very outset of the study and an unfavourable course of illness. They had a higher rehospitalisation rate, more symptoms, lower psychosocial assessment, and a poorer 2-year and even 8-year outcome. Patients from families with a fluctuating EE or a consistently low EE had better courses. Expessed emotion is therefore a valid predictor not only of symptomatic relapses, but also of other important aspects of schizophrenia. The connection between EE index and course of illness seerns not to be simply reactive or causal, but complex and non-uniform.
