Impacto de la fatiga en la percepción de salud en la enfermedad inflamatoria intestinal.

La salud de los pacientes con enfermedad inflamatoria intestinal (EII) está afectada por la fatiga, que condiciona una baja calidad de vida. Este estudio administró cuestionarios de calidad de vida y fatiga a 110 pacientes con EII, cuantificando fatiga y correlacionándola con la actividad, se determinó la afectación de la calidad de vida. Los resultados mostraron relación inversa entre fatiga y actividad de EII, con diferencias estadísticamente significativas según brote o remisión de la enfermedad. Las correlaciones entre actividad y fatiga con calidad de vida, fueron negativas. En conclusión, a mayor actividad, mayor fatiga que conlleva peor calidad de vida.

Are virtual planning and guided surgery for head and neck reconstruction economically viable?

PURPOSE: Virtual planning and guided surgery with or without prebent or milled plates are becoming more and more common for mandibular reconstruction with fibular free flaps (FFFs). Although this excellent surgical option is being used more widely, the question of the additional cost of planning and cutting-guide production has to be discussed. In capped payment systems such additional costs have to be offset by other savings if there are no special provisions for extra funding. Our study was designed to determine whether using virtual planning and guided surgery resulted in time saved during surgery and whether this time gain resulted in self-funding of such planning through the time saved. MATERIALS AND METHODS: All consecutive cases of FFF surgery were evaluated during a 2-year period. Institutional data were used to determine the price of 1 minute of operative time. The time for fibula molding, plate adaptation, and insetting was recorded. RESULTS: During the defined period, we performed 20 mandibular reconstructions using FFFs, 9 with virtual planning and guided surgery and 11 freehand cases. One minute of operative time was calculated to cost US $47.50. Multiplying this number by the time saved, we found that the additional cost of virtual planning was reduced from US $5,098 to US $1,231.50 with a prebent plate and from US $6,980 to US $3,113.50 for a milled plate. CONCLUSIONS: Even in capped health care systems, virtual planning and guided surgery including prebent or milled plates are financially viable.

Evaluation cardiologique préopératoire avant chirurgie non cardiaque: stratification du risque cardiovasculaire [Preoperative cardiac assessment before non-cardiac surgery: cardiac risk stratification].

Perioperative cardiac events occurring in patients undergoing non-cardiac surgery are a common cause of morbidity and mortality. Current guidelines recommend an individualized approach to preoperative cardiac risk stratification prior to non-cardiac surgery, integrating risk factors both for the patient (active cardiac conditions, clinical risk factors, functional capacity) and for the planned surgery. Preoperative cardiac investigations are currently limited to high-risk patients in whom they may contribute to modify the perioperative management. A multidisciplinary approach to such patients, integrating the general practitioner, is recommended in order to define an individualized peri-operative strategy.

Acute intestinal anisakiasis in Spain: a fourth-stage Anisakis simplex larva

A case of acute intestinal anisakiasis has been reported; a nematode larva being found in the submucosa of the ileum of a woman in Jaén (Spain). The source of infection was the ingestion of raw Engraulis encrasicholus. On the basis of its morphology, the worm has been identified as a fourth-stage larva of Anisakis simplex. In Spain, this is the ninth report of human anisakiasis and also probably the first case of anisakiasis caused by a fourth-stage larva of A. simplex.

Comparison of the efficacy and longevity of nonpenetrating glaucoma surgery with and without a new, nonabsorbable hydrophilic implant.

BACKGROUND AND OBJECTIVE: To compare the efficacy and longevity of nonpenetrating glaucoma surgery with and without the use of a nonabsorbable hydrophilic implant at the Oxford Eye Centre, Johannesburg, South Africa, and the Glaucoma Unit, Jules Gonin Ophthalmic Hospital, Lausanne, Switzerland. PATIENTS AND METHODS: In a nonrandomized, prospective study between March 1997 and December 2001, 48 eyes of 32 patients aged 18 to 86 years with primary open-angle glaucoma underwent nonpenetrating glaucoma surgery; 25 eyes with the implant and 23 eyes without it. Intraocular pressure (IOP) was recorded preoperatively and postoperatively at 1, 7, and 14 days, at 1, 3, and 6 months, and thereafter every 6 months. RESULTS: The mean preoperative IOP was 27.5 +/- 11.8 mm Hg (range, 20 to 64 mm Hg) in the implant group and 24.8 +/- 7.1 mm Hg (range, 16 to 38 mm Hg) in the control group. During the first 18 months of follow-up, both groups showed identical IOP progression and the mean IOP remained less than 14 mm Hg. After 2 years of follow-up, the IOP started to rise in the control group but remained stable in the implant group. After 30 months, the mean IOP was 12.4 +/- 2 mm Hg and the IOP decrease in percentage was 62% +/- 6% in the implant group (n = 13) versus 16.1 +/- 3 mm Hg and 34% +/- 13% in the control group (n = 15) (mean IOP, P = .0022; mean IOP decrease in percentage, P = .01). CONCLUSIONS: During the first 18 months, there was no difference in the outcomes between the two groups. After 2 years of follow-up, the mean IOP was lower and the IOP decrease in percentage was greater in the implant group compared with the control group.

Estudi de l’efecte del tractament amb Adalimumab sobre la microbiota associada a la mucosa intestinal en pacients amb malaltia de Crohn.

La malaltia de Crohn és una malaltia inflamatòria intestinal en la qual s´ha observat que la densitat i la diversitat bacteriana difereixen dels subjectes sans. En els últims anys s’estan emprant tractaments biològics com els anti-TNFα (Adalimumab) de manera alternativa a tractaments ja existents. Els resultats obtinguts després de l’anàlisi de la composició bacteriana de la mucosa intestinal de pacients amb Malaltia de Crohn tractats amb Adalimumab, són esperançadors ja que apunten a una recuperació del patró normal a través de la recuperació d’espècies pròpies de persones sanes i la desaparició d’aquelles més prevalents en malalts de Crohn.

Repeat Gamma Knife surgery for recurrent trigeminal neuralgia: long-term outcomes and systematic review.

Object The purpose of this study was to establish the safety and efficacy of repeat Gamma Knife surgery (GKS) for recurrent trigeminal neuralgia (TN). Methods Using the prospective database of TN patients treated with GKS in Timone University Hospital (Marseille, France), data were analyzed for 737 patients undergoing GKS for TN Type 1 from July 1992 to November 2010. Among the 497 patients with initial pain cessation, 34.4% (157/456 with ≥ 1-year follow-up) experienced at least 1 recurrence. Thirteen patients (1.8%) were considered for a second GKS, proposed only if the patients had good and prolonged initial pain cessation after the first GKS, with no other treatment alternative at the moment of recurrence. As for the first GKS, a single 4-mm isocenter was positioned in the cisternal portion of the trigeminal nerve at a median distance of 7.6 mm (range 4-14 mm) anterior to the emergence of the nerve (retrogasserian target). A median maximum dose of 90 Gy (range 70-90 Gy) was delivered. Data for 9 patients with at least 1-year followup were analyzed. A systematic review of literature was also performed, and results are compared with those of the Marseille study. Results The median time to retreatment in the Marseille study was 72 months (range 12-125 months) and in the literature it was 17 months (range 3-146 months). In the Marseille study, the median follow-up period was 33.9 months (range 12-96 months), and 8 of 9 patients (88.9%) had initial pain cessation with a median of 6.5 days (range 1-180 days). The actuarial rate for new hypesthesia was 33.3% at 6 months and 50% at 1 year, which remained stable for 7 years. The actuarial probabilities of maintaining pain relief without medication at 6 months and 1 year were 100% and 75%, respectively, and remained stable for 7 years. The systematic review analyzed 20 peer-reviewed studies reporting outcomes for repeat GKS for recurrent TN, with a total of 626 patients. Both the selection of the cases for retreatment and the way of reporting outcomes vary widely among studies, with a median rate for initial pain cessation of 88% (range 60%-100%) and for new hypesthesia of 33% (range 11%-80%). Conclusions Results from the Marseille study raise the question of surgical alternatives after failed GKS for TN. The rates of initial pain cessation and recurrence seem comparable to, or even better than, those of the first GKS, according to different studies, but toxicity is much higher, both in the Marseille study and in the published data. Neither the Marseille study data nor literature data answer the 3 cardinal questions regarding repeat radiosurgery in recurrent TN: which patients to retreat, which target is optimal, and which dose to use.

Perioperative visual loss: a rare complication of general surgery

BACKGROUND: Perioperative visual loss (PVL) refers to the loss of vision following surgery performed at distance from the visual pathways. An ischemic optic neuropathy (ION) is the most frequent clinical presentation of PVL, and can be bilateral. PATIENTS AND METHODS: A retrospective chart review of 11 consecutive patients with PVL examined between 2002 and 2007 was undertaken. RESULTS: An ION was found in all 11 cases: 8 were anterior (AION) and 3 were posterior (PION). Visual loss was bilateral in 9 patients. Mean visual acuity (VA) was 0.2 on the Snellen chart (0.74 LogMAR). Most frequently an arcuate/altitudinal visual field defect was present. PVL followed orthopedic (6), spinal (1), cardiac (2) and vascular (2) procedures. The average delay between surgery and visual loss was 32 hours (range: 0-96 hours). Average lowest perioperative hemoglobin level was 75 g/L. Average follow-up time was 14.7 months. VA improved by at least 2 Snellen lines in 5/20 eyes (25 %). CONCLUSIONS: PVL is a rare but dreadful complication of surgery, and is usually associated with severe anemia. Like other causes of ION, there is no specific therapy. Prompt correction of the anemia might decrease the rate of this complication

Epidemiology of small intestinal atresia in Europe: a register-based study.

BACKGROUND: The epidemiology of congenital small intestinal atresia (SIA) has not been well studied. This study describes the presence of additional anomalies, pregnancy outcomes, total prevalence and association with maternal age in SIA cases in Europe. METHODS: Cases of SIA delivered during January 1990 to December 2006 notified to 20 EUROCAT registers formed the population-based case series. Prevalence over time was estimated using multilevel Poisson regression, and heterogeneity between registers was evaluated from the random component of the intercept. RESULTS: In total 1133 SIA cases were reported among 5126, 164 registered births. Of 1044 singleton cases, 215 (20.6%) cases were associated with a chromosomal anomaly. Of 829 singleton SIA cases with normal karyotype, 221 (26.7%) were associated with other structural anomalies. Considering cases with normal karyotype, the total prevalence per 10 000 births was 1.6 (95% CI 1.5 to 1.7) for SIA, 0.9 (95% CI 0.8 to 1.0) for duodenal atresia and 0.7 (95% CI 0.7 to 0.8) for jejunoileal atresia (JIA). There was no significant trend in SIA, duodenal atresia or JIA prevalence over time (RR=1.0, 95% credible interval (CrI): 1.0 to 1.0 for each), but SIA and duodenal atresia prevalence varied by geographical location (p=0.03 and p=0.04, respectively). There was weak evidence of an increased risk of SIA in mothers aged less than 20 years compared with mothers aged 20 to 29 years (RR=1.3, 95% CrI: 1.0 to 1.8). CONCLUSION: This study found no evidence of a temporal trend in the prevalence of SIA, duodenal atresia or JIA, although SIA and duodenal atresia prevalence varied significantly between registers.
