Significance of cyclin D1 expression in meningiomas: a preliminary study.

Forty-four evaluable patients with intracranial meningiomas were assessed for the expression of the cell-cycle regulator cyclin D1 and of proteins involved in proliferation and apoptosis such as PCNA, MIB-1, p53 and bcl-2. Analyses were carried out by western blot and immunohistochemistry after immediate processing of fresh tumor specimens. By western blot, expression of cyclin D1 significantly correlated with p53 (p=0.02) and with proliferative activity, as assessed by PCNA expression (p=0.0009). By immunohistochemistry, a significant relationship between cyclin D1 and the proliferation marker MIB-1 was confirmed (p=0.05), whereas significance with bcl-2 expression was not found (p=0.01). Moreover, although the association with tumor grade appeared of borderline statistical significance (p=0.07), all the grade II/III meningiomas showed increased expression of cyclin D1 and high proliferative activity. In conclusion, data from this preliminary study seem to suggest a potential value of the combined expression of cyclin D1 and proliferation indicators in defining subgroups of meningiomas with a more aggressive biological behavior.     

A rural nursing practicum: making it work.

Inciting the interest of baccalaureate students in the practice of nursing in a rural setting has been an ongoing challenge for many educators. The authors identify difficulties they encountered when attempting to involve students in a rural nursing practicum and delineate several strategies used to overcome these difficulties.     

The impact of galactosaemia on quality of life—A pilot study

Galactosaemia (galactose-1-phosphate uridyltransferase deficiency) is a pan-ethnic autosomal recessive disorder of galactose metabolism, with an estimated prevalence of 1 in 40-50000. In this pilot study, we aimed to examine the impact of galactosaemia on patients' everyday emotions, schooling, work, friendships, communication, physical activities, self-esteem and body image. We interviewed all patients with galactosaemia who attended our clinic over 2002-2003, aged 6 years and above (n = 13, age range 6-23 years) and, when possible, their parents (n = 12). The questionnaire used was based on an adaptation of the Minneapolis-Manchester QOL survey and the Australian Child Health Questionnaire. Interpersonal problems, bullying and having a hard time getting along with others, excessive anger on a regular basis, sleeping problems and problems with academic achievement, particularly with mathematics, were common. Significant differences were found between patients' and parents' perceptions, with 7/13 patients nominating the dietary restrictions and 4/7 parents nominating long-term issues as the most distressing aspect of having galactosaemia. In addition, most patients felt they were treated differently from their siblings by their parents, yet all parents felt they treated their child with galactosaemia as their other children. We conclude that galactosaemia has a significant impact on the psychosocial aspects of patients' lives. Clinicians should be aware that parents and patients can have different perspectives of the impact of galactosaemia on quality of life.     

Home, training and work: mobility of British doctors

This study examines the locations of family homes, medical schools and places of specialist training, and work of doctors qualifying from UK medical schools in 5 calendar years between 1974 and 1993. The contribution of each UK region to the medical workforce relative to its population is assessed and trends over time are examined. The relationship between place of family home and medical school attended is examined for 14,108 doctors. Career appointment location and its relationship to medical school and family home loc‐ation are examined for over 4000 doctors. For the qualifiers of 1983, an additional analysis incorporating place of training is included. Large differences were found in the percentage of medical students from local family homes attending each regional medical school. In some cases differences reflected local populations but other cases had no obvious cause. Over all cohorts studied, 38% of respondents attended a medical school in the region of their family home (32% of 1993 qualifiers), 42% held a career post in the same region as their medical school, and 38% held a career post in the same region as their family home. Among the qualifiers of 1983, 65% had a career post in the same region as their postgraduate training, 34% also attended medical school in the same region, and 19% also came from family homes in the same region. More women than men took up a career post in the same region as their postgraduate training. The relationships to family home and medical school did not differ by gender. Consultants appeared slightly less likely than GPs to have stayed within a region, but this difference was not statistically significant.     

Neuropathy associated with “benign” anti-myelin-associated glycoprotein IgM gammopathy: Clinical,immunological, neurophysiological pathological findings and response to treatment in 33 cases

We studied 33 patients presenting with a peripheral neuropathy associated with non-malignant anti-myelin-associated glycoprotein (MAG) IgM monoclonal gammopathy (MG) in an attempt to delineate their clinical, immunological, electrophysiological and pathological characteristics; we also reviewed our experience concerning long-term follow-up and therapy. Peripheral neuropathy associated with non-malignant anti-MAG IgM MG was observed mostly in males (sex ratio 7.2), and mean age at onset was 67 years (range 46–81). A predominantly sensory pattern was noted in more than 80% of cases, although some patients were affected by a predominantly motor peripheral neuropathy. Although disease progression was slow in most cases, 45% of patients suffered severe disability, and in 2 cases, the patient's death appeared to stem directly from the neuropathy. The electrophysiological findings were indicative of a demyelinating process in 90% of cases, and electron microscopic examination of nerve biopsy specimens demonstrated widening of the myelin lamellae in more than 95% of cases. Most of our patients showed a disappointing response to steroids and chemotherapy or plasma exchanges. Intravenous immune globulin, evaluated in 17 patients, had a transient, mostly subjective effect in 35% and led to a clear-cut improvement in 24% of cases. We did not observe any correlation between the severity of the clinical picture and the anti-sulphoglucuronyl paragloboside antibody titre; in individual cases, clinical improvement occurred without lowering of IgM levels. Although the severity and the rate of progression may greatly vary from patient to patient, the combination of clinical, electrophysiological and pathological features delineates a characteristic pattern in peripheral neuropathy associated with non-malignant anti-MAG IgM MG.     

Is there a place for gastroenterostomy in patients with advanced cancer of the head of the pancreas?

There remains doubt about the need for gastroenterostomy in patients with advanced cancer of the pancreatic head, performed either prophylactically or when passage of food becomes impossible. The records of 142 patients admitted for advanced pancreatic cancer to the Erasmus University Hospital over a period of 11 years were reviewed. We concentrated especially on the pre- and postoperative intake of food in cases involving gastroenterostomy and the morbidity and mortality associated with abdominal surgery in these patients. Of 129 patients without symptoms of gastric outlet obstruction at the time of diagnosis, 31 underwent prophylactic gastroenterostomy. The procedure did not prevent gastric outlet obstruction in 4 patients. Of the remaining 98 patients, 15 developed gastric outlet obstruction. Cox proportional hazards analysis showed no significant difference in the interval to the occurrence of a symptomatic obstruction between these two groups, taking into account other covariables. Postoperative complications and mortality regarding a gastroenterostomy were high, ranging from 9% to 41% and 11% to 33%, respectively. Our results do not indicate that prophylactic gastroenterostomy may significantly prevent future gastric outlet obstruction; therefore, as it also increases morbidity, it should not be performed. A gastroenterostomy to relieve symptoms should be considered carefully, as the success rate is low and is accompanied by a considerable incidence of morbidity and mortality.

Resumen Persiste la duda sobre la necesidad de practicar gastroenterostomía en pacientes con cáncer avanzado de la cabeza del páncreas, así sea profiláctica o en presencia de obstrucción al paso de los alimentos. Se revisaron las historias de 142 pacientes con cáncer avanzado de la cabeza del páncreas en el Hospital de la Universidad de Erasmo observados en un periodo de 11 años. El estudio se concentré especialmente sobre la ingesta pre y postoperatoria de alimentos en los pacientos con gastroenterostomía y en la morbilidad y mortalidad asociada con la cirugía abdominal. De 129 pacientes libres de síntomas de obstrucción en el momento del diagnóstico, 31 fueron sometidos a gastroenterostomía profiláctica; el procedimiento no logró prevenir la obstrucción gástrica en 4 casos. De los 98 pacientes restantes, 15 desarrollaron obstrucción gástrico. El análisis proporcional de Cox no demostró diferencia significativa en el intervalo transcurrido hasta la aparición de los sintomas entre los dos grupos, tomando en consideración diversas variables. Las tasas de complicaciones y de mortalidad postoperatoria en relación con la gastroenterostomía fueron elevadas, 9–41% y 11–33%, respectivamente. Nuestros resultados no indican que la gastroenterostomía profiláctica pueda prevenir la obstrucción gástrica y, por cuanto incrementa la morbilidad, no debe ser realizada. La gastroenterostomía por razones de sintomatologia debe ser cuidadosamente considerada, puesto que la tasa de éxito es baja y se acompana de considerable morbilidad y mortalidad.

Résumé Réaliser une gastroentérostomie de faÇon prophylactique ou seulement lorsque l'alimentation devient impossible chez un patient ayant un cancer de la tÊte du pancréas reste une question sans réponse. Les dossiers de 142 patients ayant un cancer avancé de la tÊte du pancréas, observés à l'HÔpital Universitaire Erasmus en l'espace de 11 ans, ont été revus. Nous avons noté la possibilité d'alimentation en périodes préet postopératoire ainsi que la morbidité et mortalité en rapport avec la chirurgie chez ces patients. Des 129 patients n'ayant pas de symptÔmes d'obstruction postpylorique au moment du diagnostic, 31 ont eu une gastroentérostomie à titre prophylactique. Cette intervention n'a pu prévenir l'obstruction chez 4 de ces patients. Des 98 autres patients, 15 ont développé une obstruction postpylorique. Une analyse multifactorielle selon le modèle de Cox n'a pu démontrer de différence significative entre les deux groupes pour l'intervalle entre le moment du diagnostic et la survenue de l'obstruction. Le taux de complications et de décès postopératoires après gastroentérostomie était élevée, variant respectivement entre 9% et 41% et 11% et 33%. Nos résultats indiquent que la gastroentérostomie à titre prophylactique ne prévient pas la survenue d'une obstruction postpylorique mais qu'elle accroÎt la morbidité. Dans ces conditions, la gastroentérostomie ne devrait Être réalisée qu'en cas d'obstruction symptomatique, mais en sachant qu'elle n'est pas toujours couronnée de succès et que les taux de mortalité et de morbidité ne sont pas nuls.

     

Comparison Between Incremental and Single-Dose Allergen Administration in Bronchial Provocation Tests

To study the effect of different schedules of allergen administration on the early (EAR) and late allergic reaction (LAR), 15 asthmatic patients with dual response after allergen challenge were submitted to two consecutive bronchoprovocation tests (BPT). BPT₁ was carried out with semilogarithmic increase of allergen doses until a FEV₁ drop of 20% was recorded. BPT₂ was performed 2 weeks later using the highest allergen dose that had elicited the dual reaction in BPT₁. Both EAR and LAR were very similar for a given patient. As the allergen dose used in BPT₂ is smaller than the cumulative allergen dose administered in BPT₁, this protocol takes into account a possible influence on BPT₂ of bronchial hyperreactivity induced by BPT₁ performed 2 weeks before.     

Laparoscopic hysterectomy

Summary Thirty-three patients were selected for laparoscopic hysterectomy and operated on in the Department of Obstetrics, Gynecology and Reproductive Medicine of Clermont-Ferrand University Hospital. Surgical techniques included blunt dissection with scissors and bipolar coagulation to achieve hemostasis. A case was considered successful when all the uterine vessels were treated by laparoscopy. Twenty-four cases were completed laparoscopically (72.7%). None of these patients had postoperative bleeding; 22 had an uneventful postoperative recovery. Nine procedures were converted to laparotomy (27.3%), five because of a difficult or unsatisfactory hemostasis. We conclude that in selected cases, a total hysterectomy can be performed safely by experienced laparoscopists. Further technological progress is necessary to make this procedure more acceptable. Its value as compared to the others will have to be demonstrated.
