Restoring Tactile and Erogenous Penile Sensation in Low-Spinal-Lesion Patients: Procedural and Technical Aspects following 43 TOMAX Nerve Transfer Procedures

Background: The "TOMAX" (TO MAX-imize sensation, sexuality, and quality of life) procedure restores genital sensation in men with low spinal lesions, improving sexual health, as shown previously. It connects the dorsal nerve of the penis to the intact ipsilateral ilioinguinal nerve, unilaterally or bilaterally. This study reports on the technical aspects based on 43 TOMAX nerve transfers. Methods: In 40 patients with no penile but intact groin sensation, 43 nerve transfers were performed. Data on patient selection, surgical history, anatomy of the ilioinguinal nerve and dorsal nerve of the penis, unilateral or bilateral surgery, surgical technique, complications, and patient information were collected prospectively. Results: Regardless of origin, all patients with no penile but good groin sensation are eligible for the procedure, provided the ilioinguinal nerve is not damaged because of former inguinal surgery or absent because of anatomical variations. Selection of a unilateral or bilateral procedure depends on the presence or absence of reflex erections and bulbocavernosus reflex. Preliminary experience with the first three bilateral cases shows that it is technically feasible, with encouraging results. The surgical technique has evolved (described in detail, including video) to enhance outcome and reduce complications. Patients are better informed, resulting in realistic expectations. Conclusions: This article synthesizes the procedural and technical experience of 43 TOMAX nerve transfers. Anyone skilled in peripheral nerve surgery and microsurgery can adopt this concept and further develop it. The TOMAX procedure can then be used to restore erogenous penile sensation and improve the quality of sexual health in patients with absent penile but good groin sensatio

Restoring penis sensation in patients with low spinal cord lesions : The role of the remaining function of the dorsal nerve in a unilateral or bilateral TOMAX procedure

Aims: The recently developed TOMAX-procedure restores unilateral genital sensation, improving sexual health in men with a low spinal lesion (LSL). It connects one dorsal nerve of the penis (DNP) to the intact ipsilateral ilioinguinal nerve. We proposed bilateral neurotization for full sensation of the glans but this entails cutting both DNPs, risking patients' erection/ejaculation ability. The objective was to select patients for a bilateral TOMAX-procedure by measuring remaining DNP function, and perform the first bilateral cases. Methods In 30 LSL patients with no penile- but normal groin sensation selected for a unilateral TOMAX-procedure the integrity of the sacral-reflex-arc and DNP function was tested pre-operatively using bilateral needle electromyography (EMG)-bulbocavernosus reflex (BCR) measurements, and an interview about reflex erections (RE) ability. Results In 13 spina bifida- and 17 spinal cord injury patients [median age 29.5 years (range 13-59 years), spinal lesion T12 (incomplete) to sacral], seven (23%) patients reported RE, four (57%) with intact BCR, and of nine (30%) patients with intact BCR, four reported RE (44%). Conclusions Even patients with a LSL and no penile sensation can have signs of remaining DNP function, but cutting both DNPs to restore full glans sensation in a bilateral TOMAX-procedure might interfere with their RE/ejaculation. To avoid this risk, we propose a selecting-protocol for a unilateral- or bilateral procedure using RE and BCR measurements. Using this protocol, three patients were bilaterally operated with promising preliminary results. Full sensation of the glans could lead to further improvement in sexual function.

Central Somatosensory Networks Respond to a De Novo Innervated Penis:A Proof of Concept in Three Spina Bifida Patients

Introduction. Spina bifida (SB) causes low spinal lesions, and patients often have absent genital sensation and a highly impaired sex life. TOMAX (TO MAX-imize sensation, sexuality and quality of life) is a surgical procedure whereby the penis is newly innervated using a sensory nerve originally targeting the inguinal area. Most TOMAX-treated SB patients initially experience penile stimulation as inguinal sensation, but eventually, the perception shifts to penis sensation with erotic feelings. The brain mechanisms mediating this perceptual shift, which are completely unknown, could hold relevance for understanding the brain's role in sexual development. Aim. The aim of this study was to study how a newly perceived penis would be mapped onto the brain after a lifelong disconnection. Methods. Three TOMAX-treated SB patients participated in a functional magnetic resonance imagery experiment while glans penis, inguinal area, and index finger were stimulated with a paint brush. Main Outcome Measure. Brush stimulation-induced activation of the primary somatosensory cortex (SI) and functional connectivity between SI and remote cerebral regions. Results. Stimulation of the re-innervated side of the glans penis and the intact contralateral inguinal area activated a very similar location on SI. Yet, connectivity analysis identified distinct SI functional networks. In all three subjects, the middle cingulate cortex (MCC) and the parietal operculum-insular cortex (OIC) were functionally connected to SI activity during glans penis stimulation, but not to SI activity induced by inguinal stimulation. Conclusions. Investigating central somatosensory network activity to a de novo innervated penis in SB patients is feasible and informative. The consistent involvement of MCC and OIC above and beyond the brain network expected on the basis of inguinal stimulation suggests that these areas mediate the novel penis sensation in these patients. The potential role of MCC and OIC in this process is discussed, along with recommendations for further research

Outpatient management of childhood asthma by paediatrician or asthma nurse: randomised controlled study with one year follow up

Methods: Seventy four children referred because of insufficient control of persistent asthma were randomly allocated to 1 year follow up by a paediatrician or asthma nurse. The main outcome measure was the percentage of symptom-free days. Additional outcome measures were airway hyperresponsiveness, lung function, daily dose of inhaled corticosteroids (ICS), number of exacerbations, number of additional visits to the general practitioner, absence from school, functional health status, and disease specific quality of life. Results: There were no significant differences at the end of the 1 year study period between the two treatment groups in percentage of symptom-free days (mean difference 2.5%; 95% CI -8.8 to 13.8), airway hyperresponsiveness (log(10) PD(20) 0.06; -0.19 to 0.32), functional health status (10.1; -0.3 to 19.8), disease specific quality of life of patients (0.08; -0.9 to 0.7), and disease specific quality of life of caregivers (0.09; -0.2 to 0.3), nor in any other outcome parameters. Most outcome parameters improved considerably over the 1 year study period. These improvements were achieved although the daily dose of ICS was reduced by a mean of 26% compared with the dose received by children at referral. All parents were satisfied with the asthma care received. Conclusions: After initial assessment in a multidisciplinary clinic, childhood asthma can be successfully managed by an asthma nurse in close cooperation with a paediatrician. During close follow up by paediatrician or asthma nurse, asthma control improved despite a reduction in ICS dose

Neurological Bypass for Sensory Innervation of the Penis in Patients With Spina Bifida

Purpose: Most male patients with spina bifida have normal sexual desires. During puberty they begin to realize that they can achieve erection and sexual intercourse but without any sensation in the penis. We hypothesized that restored sensation in the penis would greatly contribute to their quality of life and sexual health. In this prospective study we investigated the outcome of a new operative neurological bypass procedure in patients with spina bifida. Materials and Methods: In 3 patients who were 17, 18 and 21 years old with a spinal lesion at L5, L4 and L3-L4, respectively, the sensory ilioinguinal nerve (L1) was cut distal in the groin and joined by microneurorrhaphy to the divided ipsilateral dorsal nerve of the penis (S2-4) at the base of the penis. All patients underwent preoperative and postoperative neurological and psychological evaluations. Results: By 15 months postoperatively all patients had achieved excellent sensation on the operated side of the glans penis. They were unequivocally positive about the results and the penis had become more integrated into the body image. In 2 patients masturbation became more meaningful and 1 became more sexually active with and without his partner. Conclusions: The newly designed neurological bypass procedure in patients with spina bifida resulted in excellent sensibility in the glans penis. The new sensation appeared to contribute to the quality of the patient sexuality and sexual functioning as well as to the feeling of being a more normal and complete individual who is more conscious of the penis. This new operation might become standard treatment in patients with spina bifida in the future

The Usability of the Preliminary ICF Core Set for Hospitalized Patients After a Hematopoietic Stem Cell Transplantation From the Perspective of Nurses: A Feasibility Study.

Background: A hematopoietic stem cell transplantation (HSCT) has a major impact on the functioning and perceived quality of life of patients. To describe the functioning of patients, a preliminary set of 53 categories of the International Classification of Functioning, Disability and Health (ICF) as relevant for HSCT patients has been selected earlier by a Delphi study. For the implementation of this preliminary ICF core set for patients after HSCT in clinical practice, a feasibility study was requested.Methods: A feasibility study was conducted in an explanatory mixed-methods research design. Qualitative data were collected cross-sectionally by semi-structured interviews based on specific topics related to feasibility regarding the use of the preliminary ICF core set for HSCT patients from the perspective of nurses (five in ICF-trained nurses and five regular, untrained, nurses). Quantitative data, were collected longitudinally by using a mobile health application based on ICF in which the ICF trained nurses registered HSCT patients ' functioning.Results: Qualitative analysis indicated that using the preliminary ICF core set is practical and acceptable for providing information about the functioning of HSCT patients from the perspective of nurses. In addition, nurses indicated a demand for this information due to its impact on multidisciplinary meetings and clinical decision-making by involving relevant aspects of the functioning of patients. Management support, trained staff, and designated time to focus on functioning are mentioned as requirements for successful implementation. Quantitative analysis demonstrated that the most used 30% (n = 17) ICF categories are included in the preliminary ICF core set for HSCT patients (n = 24). Energy (b130) was the most used ICF category. Family relationships (d760) was the most frequently and highly positively associated ICF category.Conclusions: From the perspective of nurses, the preliminary ICF core set for HSCT patients is feasible and relevant in gaining information regarding functioning. Applying this preliminary ICF core set for HSCT patients in the anamnesis and the nursing consultations contributes to this information. Further research is needed to look at the perspective of other professionals and HSCT patients themselves

Design labs for data-driven multivalence

Designing products, spaces, and services for the Everyday has become the focus of designerly research and practice over the last decade. As designers create complex systems that are space-aware, grow and dynamically morph, their tools and methods have to undergo a similar parallel transformation and extension–often towards and borrowing from technical disciplines. Current designers work with complexity and let data shape all facets and modalities of designed artifacts. This article investigates new challenges for design operating at macro, meso, and micro scales. A translational perspective is proposed together with new types of labs and design research infrastructure that address challenges and emerging needs of the design community
