Spigelian Hernia

We report on the evolution in concept and techniques that allowed us to improve the treatment of spigelian hernia, operable in day surgery in 90% of cases and through a preperitoneal and recently a preperitoneal and subfascial prosthetic repair (PHS). Background data. We propose an innovative use of the PHS mesh for spigelian hernia repair. With this new implementation, we confront the standard surgical technique and its postoperative period. Methods. From January 1992 to March 2004, we performed 2,500 hernia surgical operations, including 32 spigelian hernia repairs (1.3% of total case series). The first surgical approach used for 20 of these 32 patients (62.5% of total spigelian hernias), all electively operated on, was a classical preperitoneal repair (Wantz), performed when possible by size of defect and weight (Body Mass Index) of the patient, under local anesthesia and on a day-surgery basis. Our new modified technique takes place through the insertion of a PHS large-type mesh, whose bottom underlay portion lies flat in the preperitoneal space with the connector obliterating the hernial orifice and with the overlay portion lying on the internal oblique muscle, covered by the aponeurosis of the external oblique muscle. Results. Our modification to the classical technique consisted only in the application of a product, such as the PHS, in a hernia defect, which presented with an orifice of the size of the connector and, therefore, was easily repairable with the use of the PHS device. This approach is easier than the preperitoneal approach, its always suitable for local anaesthesia, and it gives a more comfortable postoperative period. The surgical approach may be performed completely in day surgery. Conclusions. We believe that spigelian hernia surgical repair should always be performed by means of a preperitoneal prosthesis under local anaesthesia when the patients clinical and physical conditions allow for it, always in day surgery, and using the PHS mesh when the hernia defect size fits with the connector diameter. This last possibility seems to be easier and more comfortable for the patient in the postoperative period.     

Possible mechanisms of valproate in migraine prophylaxis

Valproate has been shown to be an effective prophylactic treatment in migraine. Investigation of the mechanism of its antimigraine action is difficult due to the broad range of its biochemical effects and the complex nature of migraine pathophysiology. Valproate increases brain GABA levels and, in doing so, may suppress migraine-related events in the cortex, perivascular parasympathetics or trigeminal nucleus caudalis. There is experimental evidence that it suppresses neurogenic inflammation and directly attenuates nociceptive neurotransmission. In addition, valproate reportedly alters levels of excitatory and inhibitory neurotransmitters and exerts direct effects on neuronal membranes in vitro. Valproate's observed effect may ultimately result from a combination of actions at different loci.     

Improved survival of children with sepsis and purpura: effects of age,gender, and era

Background  

To gain insight into factors that might affect results of future case-control studies, we performed an analysis of children with sepsis and purpura admitted to the paediatric intensive care unit (PICU) of Erasmus MC-Sophia Children's Hospital (Rotterdam, The Netherlands).     

Doctor-patient communication with people with intellectual disability - a qualitative study

Background

Patients' priorities and views on quality care are well-documented in Western countries but there is a dearth of research in this area in the East. The aim of the present study was to explore Chinese patients' views on quality of primary care consultations in Hong Kong and to compare these with the items in the CARE measure (a process measure of consultation quality widely used in the UK) in order to assess the potential utility of the CARE measure in a Chinese population.

Methods

Individual semi-structured interviews were conducted on 21 adult patients from 3 different primary care clinics (a public primary healthcare clinic, a University health centre, and a private family physician's clinic). Topics discussed included expectations, experiences, and views about quality of medical consultations. Interviews were typed verbatim, and a thematic approach was taken to identify key issues. These identified issues were then compared with the ten CARE measure items, using a CARE framework: Connecting (Care Measure items 1–3), Assessing (item 4), Responding (items 5,6), and Empowering (items 7–10).

Results

Patients judged doctors in terms of both the process of the consultation and the perceived outcomes. Themes identified that related to the interpersonal process of the consultation fitted well under the CARE framework; Connecting and communicating (18/21 patients), Assessing holistically (10/21 patients), Responding (18/21 patients) and Empowering (19/21 patients). Patients from the public clinic, who were generally of lower socio-economic status, were least likely to expect holistic care or empowerment. Two-thirds of patients also judged doctors on whether they performed an adequate physical examination, and three-quarters on the later outcomes of consultation (in terms of relief or cure and/or side-effects of prescribed drugs).

Conclusion

These findings suggest that Chinese patients in Hong Kong value engaged, empathic primary care doctors and judge the quality of consultations largely on these human skills and the attitudes and values that underpin them, as well as on the perceived outcomes of treatment. The match between themes relating to consultation process and the CARE Measure items suggests utility of this measure in this population, but further quantitative validation is required.     

Ultrasound evaluation of the abductor hallucis muscle: Reliability study

Background

The Abductor hallucis muscle (AbdH) plays an integral role during gait and is often affected in pathological foot conditions. The aim of this study was to evaluate the within and between-session intra-tester reliability using diagnostic ultrasound of the dorso-plantar thickness, medio-lateral width and cross-sectional area, of the AbdH in asymptomatic adults.

Methods

The AbdH muscles of thirty asymptomatic subjects were imaged and then measured using a Philips HD11 Ultrasound machine. Interclass correlation coefficients (ICC) with 95% confidence intervals (CI) were used to calculate both within and between session intra-tester reliability.

Results

The within-session reliability results demonstrated for dorso-plantar thickness an ICC of 0.97 (95% CI: 0.99–0.99); medio-lateral width an ICC: of 0.97 (95% CI: 0.92–0.97) and cross-sectional area an ICC of 0.98 (95% CI: 0.98–0.99). Between-session reliability results demonstrated for dorso-plantar thickness an ICC of 0.97 (95% CI: 0.95 to 0.98); medio-lateral width an ICC of 0.94 (95% CI 0.90 to 0.96) and for cross-sectional area an ICC of 0.79 (95% CI 0.65 to 0.88).

Conclusion

Diagnostic ultrasound has the potential to be a reliable tool for evaluating the AbdH muscle in asymptomatic subjects. Subsequent studies may be conducted to provide a better understanding of the AbdH function in foot and ankle pathologies.
