2q34-qter duplication and 4q34.2-qter deletion in a patient with developmental delay.

The 2q3 duplication and 4q3 deletion syndromes are two conditions with variable phenotypes including Pierre-Robin sequence (PRS), limb anomalies, congenital heart defects (CHD), developmental delays and intellectual disabilities. We describe a patient born to a mother with a balanced t(2; 4) translocation who combines both a 2q34-qter duplication and a 4q34.2-qter deletion through inheritance of the derivative chromosome 4 (der(4)). He showed developmental delay, growth retardation, hearing problems, minor facial and non-facial anomalies, such as bilateral fifth finger shortness and clinodactyly, but no PRS or CHD. The comparison of his features with those of 46 and 65 published cases of 2q3 duplication and 4q3 deletion, respectively, allows us to further restrict the size of the proposed critical intervals for PRS and CHD on chromosome 4.

A NOVEL MUTATION IN BCS1L IN A PATIENT WITH AN ISOLATED MITOCHONDRIAL COMPLEX III DEFICIENCY

Background: Isolated complex III deficiencies are caused by mutations in the mitochondrial CytB gene, in the BCS1L gene coding for a CIII assembly factor and in the UQCRQ gene that codes for the ubiquinone binding protein of complex III. Objective: Description of clinical features, mitochondrial function and molecular genetic analysis in a patient with an isolated complex III deficiency. Patient: A 17 year old boy, born to consanguineous parents who presented with hypoglycemia, glycosuria, deafness, growth retardation, Fanconi Syndrome and severe lactic acidosis in the neonatal period. Methods: Activities and assembly of OXPHOS complexes were investigated spectrophotometrically and by BN-PAGE. mt-DNAwas screened for deletions. Cytochrome b (CytB) and the BCS1L gene were sequenced. Results: Isolated complex III deficiency was detected in the patient's skeletal muscle. Using BN-PAGE blotting a complex III of lower molecular weight was detected. Staining the 2D reveals a missing subunit. No mutation was detected in the mitochondrial CytB gene. Sequence analysis of BCS1L revealed a novel homozygous point mutation p.M48V. Conclusion: The patients decreased complex III activity is most likely caused by incomplete assembly of complex III due to the homozygous p. M48V mutation in the BCS1L gene.

BrainCheck - a very brief tool to detect incipient cognitive decline: optimized case-finding combining patient- and informant-based data.

INTRODUCTION: Optimal identification of subtle cognitive impairment in the primary care setting requires a very brief tool combining (a) patients' subjective impairments, (b) cognitive testing, and (c) information from informants. The present study developed a new, very quick and easily administered case-finding tool combining these assessments ('BrainCheck') and tested the feasibility and validity of this instrument in two independent studies. METHODS: We developed a case-finding tool comprised of patient-directed (a) questions about memory and depression and (b) clock drawing, and (c) the informant-directed 7-item version of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). Feasibility study: 52 general practitioners rated the feasibility and acceptance of the patient-directed tool. Validation study: An independent group of 288 Memory Clinic patients (mean ± SD age = 76.6 ± 7.9, education = 12.0 ± 2.6; 53.8% female) with diagnoses of mild cognitive impairment (n = 80), probable Alzheimer's disease (n = 185), or major depression (n = 23) and 126 demographically matched, cognitively healthy volunteer participants (age = 75.2 ± 8.8, education = 12.5 ± 2.7; 40% female) partook. All patient and healthy control participants were administered the patient-directed tool, and informants of 113 patient and 70 healthy control participants completed the very short IQCODE. RESULTS: Feasibility study: General practitioners rated the patient-directed tool as highly feasible and acceptable. Validation study: A Classification and Regression Tree analysis generated an algorithm to categorize patient-directed data which resulted in a correct classification rate (CCR) of 81.2% (sensitivity = 83.0%, specificity = 79.4%). Critically, the CCR of the combined patient- and informant-directed instruments (BrainCheck) reached nearly 90% (that is 89.4%; sensitivity = 97.4%, specificity = 81.6%). CONCLUSION: A new and very brief instrument for general practitioners, 'BrainCheck', combined three sources of information deemed critical for effective case-finding (that is, patients' subject impairments, cognitive testing, informant information) and resulted in a nearly 90% CCR. Thus, it provides a very efficient and valid tool to aid general practitioners in deciding whether patients with suspected cognitive impairments should be further evaluated or not ('watchful waiting').

Acute total hip arthroplasty for acetabular fractures in the elderly: 11 patients followed for 2 years.

We describe the use of cable fixation and acute total hip replacement for acetabular fracture in the elderly. 12 patients with acetabular fractures, having a mean age of 79 (65-93) years, were treated with cable fixation and acute total hip arthroplasty. 8 were T-shaped fractures and 4 associated fractures of the posterior column and posterior wall. 1 patient died 5 months after surgery and the remaining 11 were followed for 2 years. All patients had a good clinical outcome. Radiographic assessment showed healing of the fracture and a satisfactory alignment of the cup without loosening. This surgical technique provides good primary fixation, stabilizes complex acetabular fractures in elderly patients with osteoporotic bone and permits early postoperative mobilization.

Monitoring compliance in resistant hypertension: an important step in patient management.

Poor compliance with antihypertensive drug regimens is one recognized cause of inadequate blood pressure control. Compliance is difficult to measure, so poor adherence to treatment remains largely undiagnosed in clinical practice. When the therapeutic response to a drug is not the one expected, it is a major challenge for many physicians to decide whether the patient is a non-responder or a non-complier. Poor compliance is therefore often incorrectly interpreted as a lack of response to treatment. Not detecting non-compliance can lead to the wrong measures being taken. Electronic monitoring of compliance provides important longitudinal information about drug-intake behaviour that cannot be obtained in the clinic. Such monitoring can improve both compliance and blood pressure control, and help physicians to make more rational therapeutic decisions. A reliable assessment of compliance could have a great impact on medical costs by preventing unnecessary investigations or dose adaptations in patients who are not taking their drugs adequately, or potentially reducing the number of hospitalizations. Side-effects and lack of effectiveness are two frequent causes of poor compliance. The right choice of antihypertensive drug can therefore contribute to compliance. In this respect, it is important to find a drug regimen that is effective, long-acting and well tolerated. Long-acting antihypertensive drugs that provide good blood pressure control beyond the 24-h dosing period should perhaps be considered as drugs of choice in non-compliant patients with hypertension because they help to prevent the consequences of occasional drug omissions.

Relation soignant-soigné quand les blogs s'en mêlent [Patient-caregiver relationship: when illness blogs step in].

The use of social media as a communication tool is rapidly growing in the community, and more specifically in patients, through illness blogs. This has been true for several years in North America, but is becoming a reality in Europe as well. We report here the first results of studies on the putative psychological benefits and risks of illness blogs for their authors. We also explore the possible impact of blogging on the patient-caregiver relationship. Social media are expected to have a growing influence in certain areas of health care. Physicians should therefore stay informed about them, take advantage of their benefits, and anticipate their risks.

Cross-cultural adaptations of the Oxford-12 HIP score to the French speaking population.

BACKGROUND: An objective measurement of surgical procedures outcomes is inherent to professional practices quality control; this especially applies in orthopaedics to joint replacement outcomes. A self-administered questionnaire offers an attractive alternative to surgeon's judgement but is infrequently used in France for these purposes. The British questionnaire, the 12-item Oxford Hip Score (OHS) was selected for this study because of its ease of use. HYPOTHESIS: The objective of this study was to validate the French translation of the self-assessment 12-item Oxford Hip Score and compare its results with those of the reference functional scores: the Harris Hip Score (HHS) and the Postel-Merle d'Aubigné (PMA) score. MATERIALS AND METHODS: Based on a clinical series of 242 patients who were candidates for total hip arthroplasty, the French translation of this questionnaire was validated. Its coherence was also validated by comparing the preoperative data with the data obtained from the two other reference clinical scores. RESULTS: The translation was validated using the forward-backward translation procedure from French to English, with correction of all differences or mistranslations after systematized comparison with the original questionnaire in English. The mean overall OHS score was 43.8 points (range, 22-60 points) with similarly good distribution of the overall value of the three scores compared. The correlation was excellent between the OHS and the HHS, but an identical correlation between the OHS and the PMA was only obtained for the association of the pain and function parameters, after excluding the mobility criterion, relatively over-represented in the PMA score. DISCUSSION AND CONCLUSION: Subjective questionnaires that contribute a personal appreciation of the results of arthroplasty by the patient can easily be applied on a large scale. This study made a translated and validated version of an internationally recognized, reliable self-assessment score available to French orthopaedic surgeons. The results obtained encourage us to use this questionnaire as a complement to the classical evaluation scores and methods.

Acute ulcerative jejunal diverticulitis: case report of an uncommon entity.

Jejunal diverticulosis is a rare entity with variable clinical and anatomical presentations. Its reported incidence varies from 0.05% to 6%. Although there is no consensus on the management of asymptomatic jejunal diverticular disease, some complications are potentially life threatening and require early surgical treatment. We report a case of an 88-year-old man investigated for acute abdominal pain with a high biological inflammatory syndrome. Inflammation of multiple giant jejunal diverticulum was discovered at abdominal computed tomography (CT). As a result of the clinical and biological signs of early peritonitis, an emergency surgical exploration was performed. The first jejunal loop showed clear signs of jejunal diverticulitis. Primary segmental jejunum resection with end-to-end anastomosis was performed. Histopathology report confirmed an ulcerative jejunal diverticulitis with imminent perforation and acute local peritonitis. The patient made an excellent rapid postoperative recovery. Jejunal diverticulum is rare but may cause serious complications. It should be considered a possible etiology of acute abdomen, especially in elderly patients with unusual symptomatology. Abdominal CT is the diagnostic tool of choice. The best treatment is emergency surgical management.

The results of surgery, with or without radiotherapy, for primary spinal myxopapillary ependymoma: a retrospective study from the rare cancer network.

PURPOSE: The aim of this study was to assess the outcome of patients with primary spinal myxopapillary ependymoma (MPE). MATERIALS AND METHODS: Data from a series of 85 (35 females, 50 males) patients with spinal MPE were collected in this retrospective multicenter study. Thirty-eight (45%) underwent surgery only and 47 (55%) received postoperative radiotherapy (RT). Median administered radiation dose was 50.4 Gy (range, 22.2-59.4). Median follow-up of the surviving patients was 60.0 months (range, 0.2-316.6). RESULTS: The 5-year progression-free survival (PFS) was 50.4% and 74.8% for surgery only and surgery with postoperative low- (<50.4 Gy) or high-dose (>or=50.4 Gy) RT, respectively. Treatment failure was observed in 24 (28%) patients. Fifteen patients presented treatment failure at the primary site only, whereas 2 and 1 patients presented with brain and distant spinal failure only. Three and 2 patients with local failure presented with concomitant spinal distant seeding and brain failure, respectively. One patient failed simultaneously in the brain and spine. Age greater than 36 years (p = 0.01), absence of neurologic symptoms at diagnosis (p = 0.01), tumor size >or=25 mm (p = 0.04), and postoperative high-dose RT (p = 0.05) were variables predictive of improved PFS on univariate analysis. In multivariate analysis, only postoperative high-dose RT was independent predictors of PFS (p = 0.04). CONCLUSIONS: The observed pattern of failure was mainly local, but one fifth of the patients presented with a concomitant spinal or brain component. Postoperative high-dose RT appears to significantly reduce the rate of tumor progression.

Patient dose management in fluoroscopy : the use of DRL : P123

Purpose: To set local dose reference levels (DRL) that allow radiologists to control stochastic and deterministic effects. Methods and materials: Dose indicators for cerebral angiographies and hepatic embolizations were collected during 4 months and analyzed in our hospital. The data were compared when an image amplifier was used instead of a flat panel detector. The Mann and Whitney test was used. Results: For the 40 cerebral angiographies performed the DRL for DAP, fluoroscopy time and number of images were respectively: 166 Gy.cm2, 19 min, 600. The maximum DAP was 490 Gy.cm2 (fluoroscopy time: 84 min). No significant difference for fluoroscopy time and DAP for image amplifier and flat panel detector (p = 0.88) was observed. The number of images was larger for flat panel detector (p = 0.004). The values obtained were slightly over the present proposed DRL: 150 Gy.cm2, 15 min, 400. Concerning the 13 hepatic embolizations the DRL for DAP fluoroscopy time and number of images were: 315 Gy.cm2, 25 min, 370. The maximum DAP delivered was 845 Gy.cm2 (fluoroscopy time of 48 min). No significant difference between image amplifier and flat panel detector was observed (p = 0.005). The values obtained were also slightly over the present proposed DRL: 300 Gy.cm2, 20 min, 200. Conclusion: These results show that the introduction of flat panel detector did not lead to an increase in patient dose. A DRL concerning the cumulative dose (that allow to control the deterministic effect) should be introduced to allow radiologists to have full control on the risks associated with ionizing radiations. Results of this on going study will be presented.
