RESUMEN
BACKGROUND: Surgery for total colonic aganglionosis (TCA) is designed to preserve continence and achieve satisfactory quality of life. This study evaluated a comprehensive group of clinical and social outcomes. METHODS: An international multicentre study from eight Nordic hospitals involving examination of case records and a patient-reported questionnaire survey of all patients born with TCA between 1987 and 2006 was undertaken. RESULTS: Of a total of 116 patients, five (4·3 per cent) had died and 102 were traced. Over a median follow-up of 12 (range 0·3-33) years, bowel continuity was established in 75 (73·5 per cent) at a median age of 11 (0·5-156) months. Mucosectomy with a short muscular cuff and straight ileoanal anastomosis (SIAA) (29 patients) or with a J pouch (JIAA) (26) were the most common reconstructions (55 of 72, 76 per cent). Major early postoperative complications requiring surgical intervention were observed in four (6 per cent) of the 72 patients. In 57 children aged over 4 years, long-term functional bowel symptoms after reconstruction included difficulties in holding back defaecation in 22 (39 per cent), more than one faecal accident per week in nine (16 per cent), increased frequency of defaecation in 51 (89 per cent), and social restrictions due to bowel symptoms in 35 (61 per cent). Enterocolitis occurred in 35 (47 per cent) of 72 patients. Supplementary enteral and/or parenteral nutrition was required by 51 (55 per cent) of 93 patients at any time during follow-up. Of 56 responders aged 2-20 years, true low BMI for age was found in 20 (36 per cent) and 13 (23 per cent) were short for age. CONCLUSION: Reconstruction for TCA was associated with persistent bowel symptoms, and enterocolitis remained common. Multidisciplinary follow-up, including continuity of care in adulthood, might improve care standards in patients with TCA.
ANTECEDENTES: La cirugía de la aganglionosis colónica total (total colonic aganglionosis, TCA) está diseñada para preservar la continencia y lograr una calidad de vida satisfactoria. Este estudio evaluó un gran número de resultados clínicos y sociales. MÉTODOS: Se realizó un estudio internacional multicéntrico en ocho hospitales nórdicos en el que se incluyeron las historias clínicas de todos los pacientes nacidos con TCA entre 1987 y 2006. Se invitó a los pacientes y a sus cuidadores a responder una encuesta sobre la función intestinal, el crecimiento y las necesidades nutricionales, así como la repercusión social de la enfermedad a largo plazo. RESULTADOS: De un total de 116 pacientes, 5 (4,3%) habían fallecido y 102 respondieron la encuesta. Con una mediana de seguimiento de 12 años (rango 0,5-33), se había restablecido la continuidad intestinal en 75/102 (74%) a una mediana de edad de 11 meses (0,5-156). La mucosectomía con un manguito muscular corto y anastomosis ileoanal directa (short muscular cuff and straight ileo-anal anastomosis, SIAA) n = 29 o con reservorio en J (JIAA) n = 26 (55/72, 76%) fueron las reconstrucciones más habituales. Las complicaciones postoperatorias precoces que precisaron una intervención quirúrgica fueron muy poco frecuentes, pero se presentaron en 4/72 (5%) pacientes. Los síntomas a largo plazo relacionados con la función intestinal tras la reconstrucción, valorados en 57 niños mayores de cuatro años, fueron la dificultad para retener la defecación en 14 (25%), la encopresis en 21 (37%), las pérdidas fecales > 1/semana en 9 (16%) y el aumento de la frecuencia de defecación en 51 (89%). A largo plazo, se desarrolló una enterocolitis en 35/72 (47%) pacientes. Se precisó de nutrición enteral y/o parenteral suplementaria en algún momento del período de seguimiento en 51/93 (55%) pacientes. En los pacientes que respondieron a la encuesta entre 2 y 20 años (n = 56) de edad, se detectó un índice de masa corporal menor en 20 (35%) y una altura baja en 13 (23%) para su edad. En 35/57 (61%) pacientes mayores de 4 años con restauración del tránsito intestinal había restricciones sociales debido a los síntomas intestinales, de los que en 10 (17%) casos fueron moderadas o graves. CONCLUSIÓN: La reconstrucción de una TCA se asocia con síntomas intestinales persistentes y la enterocolitis sigue siendo frecuente. Un seguimiento multidisciplinario, incluso en la edad adulta, podría mejorar los resultados en la cirugía de la TCA.

BACKGROUND: Post-Operative Quality of Recovery Scale (PQRS) has been revised to allow for the normal variation in cognitive performance seen in healthy volunteers. This modification could result in exclusion of test subjects because of poor baseline performance. Our aim was to investigate the impact of severe disease and waiting for cancer surgery on PQRS baseline cognitive performance and exclusion rate, and also on variation in cognitive performance at test re-test. METHODS: Sixty-one subjects, 31 women diagnosed with breast cancer and waiting for surgery and 30 healthy women, performed the PQRS cognitive, nociceptive and emotional domains three times in 48 h. Exclusion rate, change in score and the proportion fulfilling 'recovery' criteria at re-tests were assessed. RESULTS: Nine out of 31 patients (29%) and two out of 30 controls (7%) had too low baseline score to be further assessed (P = 0.043). The change in score at re-tests was similar between the groups. Sixty-four per cent and 83% at 20 h and 79% and 86% at 48 h in the patient and control groups respectively fulfilled the 'recovery' criteria (P = 0.45). The 'recovery' for nociceptive and emotional distress was similar between the groups, but anxiety and sadness absolute scores were significantly higher in the patient group. CONCLUSION: Women with breast cancer waiting for surgery expressed a higher level of emotional distress, performed lower at baseline but showed no difference in test re-test variability in cognitive performance according to the PQRS when compared with controls. The considerable exclusion rate among patients waiting for cancer surgery should be acknowledged.

BACKGROUND: The impact of anaesthetic agents on cognitive recovery during the first post-operative week in a middle-aged population undergoing general anaesthesia is insufficiently studied. We hypothesised that patients receiving anaesthesia based on desflurane would have a quicker recovery and regain cognitive capacity faster than patients receiving anaesthesia based on propofol. METHODS: We performed a prospective, randomised, single-blinded study comparing the effects of desflurane and propofol as primary anaesthetic agents on cognitive recovery in 59 American Society of Anesthesiologists Physical Status Classification System I-II women undergoing breast surgery. Cognitive recovery was evaluated using the Cognitive Failure Questionnaire and a modified version of the Post-operative Quality of Recovery Scale. RESULTS: Post-operative cognitive recovery according to Cognitive Failure Questionnaire was 65% and 66% at 72 h, and 71% and 72% at 1 week for the desflurane and the propofol groups, respectively. Recovery according to Post-operative Quality of Recovery Scale was 52% and 50% at 2 h, increasing to 71% and 87% at 48 h for the desflurane and the propofol groups, respectively. At the final point of measurement (Cognitive Failure Questionnaire 1 week, Post-operative Quality of Recovery Scale 48 h), many of the patients had still not reached their baseline cognitive performance. There was no difference in overall cognitive recovery between the desflurane and propofol groups. CONCLUSION: Cognitive recovery was not complete 1 week after surgery in any of the groups. There was no difference in the rate of cognitive recovery in middle-aged patients receiving desflurane or propofol anaesthesia during ambulatory breast surgery.

STUDY DESIGN: A complex set-up was used to investigate kinematics and ground reaction forces. SETTING: Motor Control and Physical Therapy Research Laboratory, Neurotec Department, Karolinska Institutet, Huddinge, Sweden. OBJECTIVE: To investigate how men and women with spinal cord injury (SCI) perform transfers from table to wheelchair with regard to timing and magnitude of force generation beneath the hands and associated body movements. METHODS: A total of 13 subjects (seven men, six women) with thoracic SCI. Kinematics of body movement were recorded (Elite 2000 system) simultaneously with the signals from three force plates (AMTI) placed beneath the buttocks and hands. Temporal and spatial parameters regarding head, trunk and trailing arm displacement, loading amplitudes and loading torque directions of both hands were analyzed for each trial and subject and compared between genders. RESULTS: Men and women used similar amplitudes of head bending and forward displacement of the trailing shoulder, while female subjects had significantly larger trunk rotation. Both genders applied significantly more weight on the trailing hand. Differences between genders were seen in direction and timing of peak torque beneath the hands. CONCLUSIONS: The forces beneath the trailing hand were larger than those in the leading, if there is weakness or pain in one arm, this arm should be selected as the leading. To avoid excessive load on the arms, technical aids and environmental factors should be very well adapted. SPONSORSHIP: This project was funded by the Swedish Research Council and the Health Care Science Committee of Karolinska Institutet.

To analyse the potential reaction to firegenerated heat pulses, seeds of 12 species of plants and rhizomes of three species were exposed to elevated temperatures for 10 min. The tested material split into three groups with respect to heat tolerance: (1) the rhizomes, for which the lethal temperatures were in the range 55-59° C; (2) the seeds of most of the species tested, for which the lethal temperatures were in the range 65-75° C; (3) The seeds of two species of Leguminosae and three species of Geranium for which the lethal temperatures were around 100° C. For all three Geranium species and for one of the legume species, Anthyllis vulneraria, exposure temperatures above ca. 45° C resulted in dormancy release, and maximum germination occurred above 60-65° C. Speed of germination was little affected for most species, except after exposure to nearlethal temperatures, where it slowed down dramatically, although the seedlings emerging were healthy. We conclude that due to sharp temperature gradients in the soil during fire, differences in heat tolerance between species in most cases are not large enough to be a decisive factor in their post-fire colonising success. There are exceptions: the seeds of certain taxa that are impermeable to water in the dormant state, some of which have heat triggered germination.
