Fourth consensus of the International Society for Premenstrual Disorders (ISPMD): auditable standards for diagnosis and management of premenstrual disorder.

Whilst professional bodies such as the Royal College and the American College of Obstetricians and Gynecologists have well-established standards for audit of management for most gynaecology disorders, such standards for premenstrual disorders (PMDs) have yet to be developed. The International Society of Premenstrual Disorders (ISPMD) has already published three consensus papers on PMDs covering areas that include definition, classification/quantification, clinical trial design and management (American College Obstetricians and Gynecologists 2011; Brown et al. in Cochrane Database Syst Rev 2:CD001396, 2009; Dickerson et al. in Am Fam Physician 67(8):1743-1752, 2003). In this fourth consensus of ISPMD, we aim to create a set of auditable standards for the clinical management of PMDs. All members of the original ISPMD consensus group were invited to submit one or more auditable standards to be eligible in the inclusion of the consensus. Ninety-five percent of members (18/19) responded with at least one auditable standard. A total of 66 auditable standards were received, which were returned to all group members who then ranked the standards in order of priority, before the results were collated. Proposed standards related to the diagnosis of PMDs identified the importance of obtaining an accurate history, that a symptom diary should be kept for 2 months prior to diagnosis and that symptom reporting demonstrates symptoms in the premenstrual phase of the menstrual cycle and relieved by menstruation. Regarding treatment, the most important standards were the use of selective serotonin reuptake inhibitors (SSRIs) as a first line treatment, an evidence-based approach to treatment and that SSRI side effects are properly explained to patients. A set of comprehensive standards to be used in the diagnosis and treatment of PMD has been established, for which PMD management can be audited against for standardised and improved care.

What kind of doctor would you like me to be?

BACKGROUND: The modern medical school curriculum highlights the importance of good communication skills, although some clinicians still remain sceptical about the reduction of core science teaching in favour of these so-called softer skills. Previous studies into these topics are few and contradictory, with a heavy dependence on methodology and geographical source. METHODS: A semi-structured interview was conducted using the question 'I am about to qualify as a doctor in less than a year's time. As a patient, what advice would you give me? What kind of doctor would you like me to be if you came to me with an illness?' Responses were recorded anonymously on paper, verbatim. The responses were grouped into four broad classifications: personal qualities; communication skills; knowledge and intelligence; and manual skills. RESULTS: Data were collected from 51 patients. In total 118 attributes were identified and categorised. DISCUSSION: This education evaluation indicates that the patients we talked with in the UK counties of Shropshire and Staffordshire overwhelmingly sought doctors with good personal qualities and communication skills. Of the attributes recorded, 92 per cent were related to such qualities, with only 8 per cent emphasising knowledge and intelligence, and with no comments on manual skills. The results support the current emphasis in UK medical schools on communication skills and professionalism, and the development of personal qualities through the promotion of humanities teaching. The modern medical school curriculum highlights the importance of good communication skills.

Lateral inhibition in the auditory cortex: an EEG index of tinnitus?

Auditory ERPs were recorded from eight tinnitus patients and 12 controls. Tone pips of 1000 and 2000 Hz, as well as the patient's tinnitus pitch (around 4000 Hz) were used. Controls received tone pips at 1000, 2000, and 4000 Hz. Tones were presented at 30, 36, 42, 48 and 54 dB/SL. The intensity dependence of the auditory N100 was calculated for each frequency in each group. Patients showed a steeper response to the tinnitus frequency than responses to the 4000 Hz tone in controls. In contrast, intensity-dependence to the 2000 Hz tones was significantly decreased in patients (two-tailed Wilcoxon-Mann-Whitney U-test, p < 0.05). Responses to the 1000 Hz tones were similar for both groups. This reduced intensity dependence is hypothesized to result from lateral inhibition arising from tinnitus related activity in the 4000 Hz isofrequency region.

Addition of Transiently-Generated Methyl o-Lithiobenzoate to Imines. An Isoindolone Annulation.

Addition of phenyllithium to a mixture of an imine, methyl o-iodobenzoate, and BF(3).etherate at -105 degrees C gives good to excellent yields of isoindolones. The transient formation of methyl o-lithiobenzoate is proposed, which is formed by a rapid lithium/iodide exchange reaction of the phenyllithium with methyl o-iodobenzoate in the presence of the imine. The transiently generated anions can then be captured by the BF(3)-activated imines to form the isoindolones in good to high yield. The reactions conditions are sufficiently mild, and selective, to permit functional groups such carbmethoxy and aryl bromide, which could otherwise react with the added PhLi, to be tolerated.

VNS and depression: current status and future directions.

Vagus nerve stimulation (VNS) is an established anticonvulsant therapy in treatment-resistant patients with epilepsy. The known anatomical projections of the vagus nerve to many brain regions that have been implicated in mood disorders suggest that VNS may also have useful antidepressant effects. There has been growing interest in the potential application of VNS in the nonpharmacological management of treatment-resistant depression. Results from an open-label study, in which 59 subjects with treatment-resistant depression were treated for 10 weeks with VNS therapy, reported a 31% response rate. In a recent controlled double-blind trial of VNS and depression, short-term treatment for 10 weeks failed to demonstrate statistical improvement over sham treatment. Results from the long-term phase of this trial may be more significant, however published data are awaited.

Validation and implementation of array comparative genomic hybridisation as a first line test in place of postnatal karyotyping for genome imbalance.

BACKGROUND: Several studies have demonstrated that array comparative genomic hybridisation (CGH) for genome-wide imbalance provides a substantial increase in diagnostic yield for patients traditionally referred for karyotyping by G-banded chromosome analysis. The purpose of this study was to demonstrate the feasibility of and strategies for, the use of array CGH in place of karyotyping for genome imbalance, and to report on the results of the implementation of this approach. RESULTS: Following a validation period, an oligoarray platform was chosen. In order to minimise costs and increase efficiency, a patient/patient hybridisation strategy was used, and analysis criteria were set to optimise detection of pathogenic imbalance. A customised database application with direct links to a number of online resources was developed to allow efficient management and tracking of patient samples and facilitate interpretation of results. Following introduction into our routine diagnostic service for patients with suspected genome imbalance, array CGH as a follow-on test for patients with normal karyotypes (n = 1245) and as a first-line test (n = 1169) gave imbalance detection rates of 26% and 22% respectively (excluding common, benign variants). At least 89% of the abnormalities detected by first line testing would not have been detected by standard karyotype analysis. The average reporting time for first-line tests was 25 days from receipt of sample. CONCLUSIONS: Array CGH can be used in a diagnostic service setting in place of G-banded chromosome analysis, providing a more comprehensive and objective test for patients with suspected genome imbalance. The increase in consumable costs can be minimised by employing appropriate hybridisation strategies; the use of robotics and a customised database application to process multiple samples reduces staffing costs and streamlines analysis, interpretation and reporting of results. Array CGH provides a substantially higher diagnostic yield than G-banded chromosome analysis, thereby alleviating the burden of further clinical investigations.
