RESUMEN

@#Intrauterine device use as contraceptionoffers the benefits of being affordable, long- acting, highly effective, and reversible. However, like any foreign body, it can be prone to certain complications, at times, with very serious consequences. Migration is the rarest but most feared complication. This is a report of the case of 72-year old woman with anine-month history of right lower quadrant abdominal pain. Work ups pointed to a migrated intrauterine device.The patient subsequently underwent laparoscopic removal of the foreign body with omental biopsy which laterrevealed metastatic adenocarcinoma from a primary ovarian malignancy.

RESUMEN

BACKGROUND: Increasingly, health researchers must demonstrate the impact and real-life applications of their research. We investigated how health researchers with expertise in knowledge translation report research translation activities and impact on their curriculum vitae (CV). METHODS: We conducted a cross-sectional survey of health researchers with expertise in knowledge translation as we anticipated best practices in CV reporting from this specialized group. Our survey asked participants about their reporting of research translation and impact activities on their CVs, intention to report, and barriers and facilitators to reporting such activities on their CVs. We calculated univariate descriptive statistics for all quantitative data. Linear regression models determined predictors of researchers' intention to report research translation and impact activities on their CVs. We analyzed open-ended qualitative responses using content analysis. RESULTS: One hundred and fifty-three health researchers responded to the survey (response rate = 29%). Most respondents were Canadian, were female, and had a doctoral degree. Eighty-two percent indicated they reported at least one research translation and/or impact indicator on their CVs. Of those, health researchers commonly reported the following: advisory/regulatory committee membership related to research program (83%), research translation award(s) (61%), and academic performance assessments (59%). Researchers least commonly indicated the following: citation metric scores (31%), summaries of impact (21%), and requests to use research materials and/or products (19%). Fewer than half of the health researchers intended to report knowledge translation (43%) and impact (33%) on their CVs. Strong beliefs about capabilities and consequences of reporting research translation and/or impact were significant predictors of intention. Main barriers were as follows: CV templates do not include research translation and impact activities, participants perceived employers do not value research translation and impact activities, and lack of metrics to evaluate research translation and impact. Ninety-six percent were unaware of a CV template formatted to include research translation and/or impact reporting. CONCLUSIONS: Knowledge translation and impact indicators on the CV are inconsistently reported by our sample of health researchers. Modifiable barriers should be addressed to support more consistent reporting of such activities, including providing a CV template that includes research translation and impact as well as clear metrics to quantify them.

RESUMEN

High-throughput sequencing (HTS) has revolutionized genetics by enabling the detection of sequence variants at hitherto unprecedented large scale. Despite these advances, however, there are still remaining challenges in the complete coverage of targeted regions (genes, exome or genome) as well as in HTS data analysis and interpretation. Moreover, it is easy to get overwhelmed by the plethora of available methods and tools for HTS. Here, we review the step-by-step process from the generation of sequence data to molecular diagnosis of Mendelian diseases. Highlighting advantages and limitations, this review addresses the current state of (1) HTS technologies, considering targeted, whole-exome, and whole-genome sequencing on short- and long-read platforms; (2) read alignment, variant calling and interpretation; as well as (3) regulatory issues related to genetic counseling, reimbursement, and data storage.

RESUMEN

Objective: To determine symptoms and characteristics of chronic sensory neuropathy in patients treated with oxaliplatin and docetaxel, including patterns of somatosensory abnormalities, pain descriptors, and psychological functioning. Design: A retrospective cross-sectional study. Setting: A chronic pain research center. Subjects: Thirty-eight patients with chronic peripheral pain and/or dysesthesia following chemotherapy. Methods: Sensory profiles, psychological functioning, and quality of life were assessed using standardized questionnaires. In addition, standardized quantitative sensory testing and nerve conduction studies were carried out. Results: The sensory profiles and clinical symptoms were very similar in the two groups. Pricking, numbness, and burning were common descriptors in both groups, and the predominant finding was sensory loss to A beta-mediated sensory modalities with decreased mechanical and vibration detection thresholds. A high frequency of abnormalities in thermal sensory limen and the presence of paradoxical heat sensation seem to be sensitive markers of small fiber loss. Both groups had mainly sensory, axonal large fiber or mixed fiber polyneuropathy, which tended to be most severe in the oxaliplatin group. Conclusions: Both oxaliplatin-induced and docetaxel-induced polyneuropathies represent a significant problem that affects the daily life of the patients. Our results, defining the somatosensory phenotype, can improve the understanding of the pathophysiological mechanisms useful for future studies in the tailored treatment of prevention of chemotherapy-induced peripheral neuropathy and pain.

RESUMEN

INTRODUCTION: We examined the effect of topical lidocaine on the function of small and large fibers in patients with peripheral neuropathic pain due to traumatic or postoperative nerve injury. METHODS: In an open-label study, 24 patients were treated with a 5% lidocaine patch for up to 12 weeks. We recorded contact heat evoked potentials (CHEPs) and performed quantitative sensory testing (QST) before and after treatment with the contralateral side as control. RESULTS: Twenty-one patients (mean age 47.6 ± 13.5 years) completed the study. Lidocaine increased cold pain threshold (P = 0.04) and reduced CHEP amplitude (P = 0.007) with no effect on other QST parameters. Patients responding to treatment had less cold detection deficit on the affected side and had a larger increase in cold pain detection threshold following treatment than nonresponders. CONCLUSIONS: Controlled trials are warranted to further understand the mechanisms mediating the effects of topical lidocaine.

RESUMEN

Complex regional pain syndrome (CRPS) is characterised by autonomic, sensory, and motor disturbances. The underlying mechanisms of the autonomic changes in CPRS are unknown. However, it has been postulated that sympathetic inhibition in the acute phase with locally reduced levels of noradrenaline is followed by an up-regulation of alpha-adrenoceptors in chronic CRPS leading to denervation supersensitivity to catecholamines. This exploratory study examined the effect of cutaneous sympathetic activation and inhibition on cutaneous noradrenaline release, vascular reactivity, and pain in CRPS patients and in healthy volunteers. Seven patients and nine controls completed whole-body cooling (sympathetic activation) and heating (sympathetic inhibition) induced by a whole-body thermal suit with simultaneous measurement of the skin temperature, skin blood flow, and release of dermal noradrenaline. CRPS pain and the perceived skin temperature were measured every 5 min during thermal exposure, while noradrenaline was determined from cutaneous microdialysate collected every 20 min throughout the study period. Cooling induced peripheral sympathetic activation in patients and controls with significant increases in dermal noradrenaline, vasoconstriction, and reduction in skin temperature. The main findings were that the noradrenaline response did not differ between patients and controls or between the CRPS hand and the contralateral unaffected hand, suggesting that the evoked noradrenaline release from the cutaneous sympathetic postganglionic fibres is preserved in chronic CRPS patients.

RESUMEN

PURPOSE OF REVIEW: This review briefly discusses the definition and clinical presentation of neuropathic pain and highlights recent advances in the treatment of neuropathic pain. RECENT FINDINGS: Recent publications have confirmed the efficacy of tricyclic antidepressants, gabapentin, pregabalin, opioids, and tramadol for various neuropathic pain conditions. Selective serotonin noradrenaline reuptake inhibitors have been found to reduce pain in painful neuropathy. The new anticonvulsant lacosamide may have some effect in painful polyneuropathy, whereas levetiracetam has failed to relieve postmastectomy and spinal cord injury pain. The role of the old anticonvulsant phenytoin is still unsettled. A recent trial has found an effect of cannabinoids also in peripheral neuropathic pain. Various topical treatments such as topical lidocaine, topically applied capsaicin in high concentrations (8%), and botulinum toxin have recently been shown to have a pain-relieving effect in various peripheral neuropathic pain conditions. Spinal cord and transcranial magnetic stimulation are stimulation therapies with some evidence for efficacy. SUMMARY: Treating neuropathic pain remains a great challenge, and the treatment has to be individualized to the single patient, taking into account side effects, pain type, comorbidities, and drug interactions.

RESUMEN

A new B-lymphoma cell line (DEAU-cell line) was established from a diffuse large-cell lymphoma (centroblastic type) and was successfully grafted in athymic nude mice. Monoclonal antibodies (MoAbs) were generated using splenocytes of DEAU-tumor bearing mice. Before the fusion experiments, cellular immunity of the mice bearing growing DEAU tumors was restored by injection of spleen cells from conventional Balb/C mice. Spleen cells from conventional Balb/C mice immunized with DEAU-cell line were also used for the generation of MoAbs. Four MoAbs (DBB.42 and DBA.44 from normal Balb/C mice, and DNA.7 and DND.53 from athymic nude mice) were investigated because they identified B-cell-associated antigens not destroyed by fixatives. DBB.42 recognized a pan-B cell-associated antigen (molecular weight (mol wt) = 45 Kd). DBA.44 detected a B-cell antigen (mol wt not determined) expressed on a subpopulation of B lymphocytes in the mantle zone of lymphoid follicles. DNA.7 also defined a B-cell antigen (43 Kd) mainly expressed on germinal center cells. Similarly, DND.53 recognized a B-cell antigen (two bands of mol wt 20 Kd and 35 Kd, respectively) mainly expressed on germinal center cells and mantle zone lymphocytes and interdigitating reticulum cells in the paracortical area. Major differences were found in the reactivities of these MoAbs on malignant lymphomas. DBB.42 was positive with almost all B-cell lymphomas and some T-cell lymphomas. Within the group of low-grade B-cell lymphomas, DBA.44 reacted principally with hairy-cell leukemia. DNA.7 reacted mainly with high-grade B-cell lymphomas with a weak positivity in low-grade B-cell lymphomas. DND.53 reacted with all but one B-cell lymphoma, cells of histiocytosis X, and Reed-Sternberg cells. These findings indicate that new MoAbs can be generated by using spleen cells from athymic mice bearing human tumors as well as by new lymphoid cell lines. The MoAbs so generated, as in the present study, are deemed potentially useful for the recognition of B-cell lymphomas in routine diagnostic histopathology. In addition, DND.53 could be of value for the diagnosis of histiocytosis X and the detection of Reed-Sternberg cells in Hodgkin's disease.
