A modality-specific somatosensory evoked potential test protocol for clinical evaluation: A feasibility study

ObjectiveWe aimed to establish an objective neurophysiological test protocol that can be used to assess the somatosensory nervous system.MethodsIn order to assess most fiber subtypes of the somatosensory nervous system, repetitive stimuli of seven different modalities (touch, vibration, pinprick, cold, contact heat, laser, and warmth) were synchronized with the electroencephalogram (EEG) and applied on the cheek and dorsum of the hand and dorsum of the foot in 21 healthy subjects and three polyneuropathy (PNP) patients. Latencies and amplitudes of the modalities were assessed and compared. Patients received quantitative sensory testing (QST) as reference.ResultsWe found reproducible evoked potentials recordings for touch, vibration, pinprick, contact-heat, and laser stimuli. The recording of warm-evoked potentials was challenging in young healthy subjects and not applicable in patients. Latencies were shortest within Aβ-fiber-mediated signals and longest within C-fibers. The test protocol detected function loss within the Aβ-fiber and Aδ-fiber-range in PNP patients. This function loss corresponded with QST findings.ConclusionIn this pilot study, we developed a neurophysiological test protocol that can specifically assess most of the somatosensory modalities. Despite technical challenges, initial patient data appear promising regarding a possible future clinical application.SignificanceEstablished and custom-made stimulators were combined to assess different fiber subtypes of the somatosensory nervous system using modality-specific evoked potentials.

参芪润肠通便汤治疗小儿便秘的临床疗效

目的观察参芪润肠通便汤治疗小儿便秘的临床疗效。方法选定麻城市人民医院中医儿科门诊治疗的小儿便秘患儿80例,研究时段自2017年2月—2019年1月,按照治疗方式进行分组,分对照组(40例,常规药物治疗)、试验组(40例,参芪润肠通便汤治疗),回顾分析患儿临床资料,比较临床疗效、症状积分。结果试验组临床总有效率(95.00%)显著较对照组(77.50%)高,P<0.05;试验组治疗前1 d大便全程干燥、腹部胀满、胃纳减退评分与对照组相比存在差异,但P<0.05,治疗2周后两组上述评分均降低,且试验组较对照组低,P<0.05。结论针对小儿便秘患儿,参芪润肠通便汤可改善患者症状,促进其病情恢复,患儿整体状态得以改善,值得借鉴。     

Anatomically contoured large femoral heads can reduce iliopsoas impingement: A cadaver verification study

While use of large heads in total hip arthroplasty (THA) continues to grow, concerns have been raised regarding anterior hip pain resulting from impingement of the prosthetic head against soft-tissues like the iliopsoas. To address these concerns, a new anatomically contoured head (ACH) was developed. In this study cadaver tests were utilized to show that iliopsoas impingement/tenting caused by conventional heads is significantly relieved with the more rounded and reduced distal profile of the ACH. Thus, the ACH implant may be able to decrease the risk of soft-tissue impingement with conventional heads, particularly in the smaller hip.     

Clinical analysis of high-intensity focussed ultrasound ablation for abdominal wall endometriosis: a 4-year experience at a specialty gynecological institution

Objective: To evaluate the long-term clinical effect of high-intensity focussed ultrasound (HIFU) as a non-invasive modality for ablation of abdominal wall endometriosis (AWE) foci.

Methods: All women who were diagnosed with cutaneous endometriosis and underwent HIFU ablation and 4-year follow-up were included. Patient symptoms, imaging performed, HIFU ablation, recurrence, lesion location, size and number were collected and analyzed.

Results: A total of 51 women with 57 painful abdominal wall masses with a median volume of 4.00?cm³ and a mean age of 30.5±2.12 years were treated with HIFU. The main symptoms were a palpable painful abdominal mass (93%), protrusion of the skin (28.1%, 16) or lack of protrusion of the skin (71.9%, 41). Ultrasound was initially performed in 100% (51) of women, whereas 6% (3) required MRI examinations to distinguish the features and range of the masses. Ablation was performed with a median 300?s of sonication time, 40?min treatment time, 150?W of power and 41800?J of total energy to treat lesions that were a median volume of 3.83?cm³. No severe complications occurred, except in one patient with a first-degree skin burn, during the 48-month follow-up period. The pooled recurrence of cutaneous endometriosis occurred in 3.9% (2) of women.

Conclusion: The diagnosis of AWE should be confirmed with imaging of the lesion number, location, size and features before HIFU ablation. HIFU should be the first choice for the treatment of AWE as it is a non-invasive method, with high efficiency and safety and rapid postoperative recovery.

Systematic Review of the Effectiveness of Involving Parents During Painful Interventions for Their Preterm Infants

ObjectiveTo systematically review the literature related to the effectiveness of parents’ active involvement during painful interventions for their preterm infants.Data SourcesWe performed a systematic search of PubMed, EMBASE/Ovid, CINAHL, Livivio, and PsycInfo using the keywords “preterm infants,” “pain,” and “parents.”Study SelectionArticles were eligible for inclusion if they were published between 2000 and 2021 and reported randomized controlled trials (RCTs) in which preterm infants underwent painful interventions, and parents were present and actively involved in pain-reducing measures.Data ExtractionWe used the Consolidated Standards of Reporting Trials (CONSORT) checklist for RCTs for data extraction. We assessed methodologic quality using critical appraisal for RCTs according to the Joanna Briggs Institute.Data SynthesisIn total, 22 articles met the inclusion criteria. These articles reported 19 studies focused on kangaroo/skin-to-skin care, one focused on breastfeeding, and two focused on facilitated tucking. The methods used to evaluate pain in the infant varied substantially. Overall, kangaroo/skin-to-skin care and facilitated tucking resulted in clinically and statistically significant decreases in pain. For breastfeeding, effectiveness was linked to a more mature sucking pattern of the preterm infant.ConclusionThe current evidence suggests that involving parents in pain-reducing measures during painful interventions for their preterm infants is beneficial. However, more research is needed for the different methods of involving parents in pain-reducing measures.
