Tld1 is a regulator of triglyceride lipolysis that demarcates a lipid droplet subpopulation.

Cells store lipids in the form of triglyceride (TG) and sterol ester (SE) in lipid droplets (LDs). Distinct pools of LDs exist, but a pervasive question is how proteins localize to and convey functions to LD subsets. Here, we show that the yeast protein YDR275W/Tld1 (for TG-associated LD protein 1) localizes to a subset of TG-containing LDs and reveal it negatively regulates lipolysis. Mechanistically, Tld1 LD targeting requires TG, and it is mediated by two distinct hydrophobic regions (HRs). Molecular dynamics simulations reveal that Tld1's HRs interact with TG on LDs and adopt specific conformations on TG-rich LDs versus SE-rich LDs in yeast and human cells. Tld1-deficient yeast display no defect in LD biogenesis but exhibit elevated TG lipolysis dependent on lipase Tgl3. Remarkably, overexpression of Tld1, but not LD protein Pln1/Pet10, promotes TG accumulation without altering SE pools. Finally, we find that Tld1-deficient cells display altered LD mobilization during extended yeast starvation. We propose that Tld1 senses TG-rich LDs and regulates lipolysis on LD subpopulations.

Evaluation of primary care physicians' competence in selective skin tumour triage after short versus long dermoscopy training: a randomized non-inferiority trial.

BACKGROUND: Although primary care physicians (PCPs) play a key role in skin cancer screening, their skills in detecting malignant tumours is suboptimal. OBJECTIVES: To determine whether a short dermoscopy e-learning course (4 h) in skin tumour diagnosis for PCPs is non-inferior to a long course (12 h) in selective triage of skin lesions. Secondly, to evaluate whether regular refresher training sessions are necessary to maintain the PCPs' skills in the medium term. METHODS: A randomized 2 × 2 factorial non-inferiority trial was conducted online over an 8-month period among 233 PCPs including 126 certified general practitioners, 94 PCPs in training, and 13 occupational physicians, all without prior advanced dermoscopy training. Participants were randomized 1:1:1:1 to receive short training and mandatory refreshers (n = 58), short training and optional refreshers (n = 59), long training and mandatory refreshers (n = 58), or long training and optional refreshers (n = 58). PCPs' skills were evaluated before training (T0), immediately after training (T1) to test the non-inferiority, and after 5 months (T2) to evaluate the impact of the refreshers. The primary endpoint was the difference in the change of score after short and long training. The non-inferiority margin was set at -28%. RESULTS: Among the 233 randomized participants, 216 (93%) completed T1 and 197 (84.5%) completed T2. For short versus long training, the primary endpoint was 1.392 (95% CI: 0.138; 2.645) in the per-protocol population (p < 0.001) and 1.016 (95% CI: -0.224; 2.256) in the modified intention-to-treat population (p < 0.001). After training, the type of refresher showed no impact on the score (p = 0.840). However, PCPs who completed all refreshers showed the best mean overall score at T2 (p < 0.001). CONCLUSIONS: These findings confirm that short dermoscopy e-learning is non-inferior in training PCPs to triage skin lesions compared to long training. After training, regular refreshers are important to maintain the PCPs' acquired skills over time.

Capturing the Liquid-Crystalline Phase Transformation: Implications for Protein Targeting to Sterol Ester-Rich Lipid Droplets.

Lipid droplets are essential organelles that store and traffic neutral lipids. The phospholipid monolayer surrounding their neutral lipid core engages with a highly dynamic proteome that changes according to cellular and metabolic conditions. Recent work has demonstrated that when the abundance of sterol esters increases above a critical concentration, such as under conditions of starvation or high LDL exposure, the lipid droplet core can undergo an amorphous to liquid-crystalline phase transformation. Herein, we study the consequences of this transformation on the physical properties of lipid droplets that are thought to regulate protein association. Using simulations of different sterol-ester concentrations, we have captured the liquid-crystalline phase transformation at the molecular level, highlighting the alignment of sterol esters in alternating orientations to form concentric layers. We demonstrate how ordering in the core permeates into the neutral lipid/phospholipid interface, changing the magnitude and nature of neutral lipid intercalation and inducing ordering in the phospholipid monolayer. Increased phospholipid packing is concomitant with altered surface properties, including smaller area per phospholipid and substantially reduced packing defects. Additionally, the ordering of sterol esters in the core causes less hydration in more ordered regions. We discuss these findings in the context of their expected consequences for preferential protein recruitment to lipid droplets under different metabolic conditions.

Self-reported body silhouettes: a diagnostic instrument for anthropometric parameters.

OBJECTIVE: Routine body size measurement of anthropometric values requires professionals, standardized techniques, and calibrated tools. Therefore, there is a need for easier screening tools such as the self-reported body silhouette (Self-bosi). The aim of this study was to analyze the performance of Self-bosi as a proxy of anthropometric values. STUDY DESIGN: Prospective analytic study of the Health Workers Cohort Study. METHODS: Adult participants of the Health Workers Cohort Study were included. Then, through the calculation sensitivity and specificity of Self-bosi to detect abnormal waist circumference (WC) (≥90 cm for male and ≥80 cm for female participants), elevated body fat percentage (BF%) (≥25% for male and ≥35% for female participants), as well as overweight and obesity (≥25 kg/m2) and obesity (≥30 kg/m2). RESULTS: A total of 2471 male and 5940 female participants were analyzed. Overall, Self-bosi discriminate high WC values (area under the curve [AUC]; male participants: 0.80, female participants: 0.82); increased BF% (AUC: male participants: 0.78, female participants: 0.83); overweight and obesity (AUC: male participants: 0.81, female participants: 0.86); and obesity (AUC: male participants: 0.83, female participants: 0.89). CONCLUSION: Self-bosi is an accurate method to assess increased WC, BF%, obesity, and overweight-obesity in Mexican adults. Given its simplicity and low-cost of the self-reported body silhouette, it might be considered a useful anthropometric screening instrument in large scale epidemiological research.

A simple nomogram for early postoperative risk prediction of clinically relevant pancreatic fistula after pancreatoduodenectomy.

PURPOSE: Postoperative pancreatic fistulae (POPF) present a serious and life-threatening complication after pancreatic head resections (PD). Therefore, reliable risk stratification to identify those at risk is urgently needed. The aim of this study was to identify postoperative laboratory parameters for the prediction of POPF in the early postoperative period. METHODS: One hundred eighty-two patients who underwent PD from 2012 until 2017 were retrospectively analyzed. Multivariate logistic regression was performed using the GLM (general linear model) method for model building. Two nomograms were created based on the GLM models of postoperative day one and postoperative day one to five. A cohort of 48 patients operated between 2018 and 2019 served as internal validation. RESULTS: Clinically relevant pancreatic fistulae (CR-POPF) were present in 16% (n = 29) of patients. Patients with CR-POPF experienced significantly more insufficiencies of gastroenterostomies, delayed gastric emptying, and more extraluminal bleeding than patients without CR-POPF. Multivariate analysis revealed multiple postoperative predictive models, the best one including ASA, main pancreatic duct diameter, operation time, and serum lipase as well as leucocytes on day one. This model was able to predict CR-POPF with an accuracy of 90% and an AUC of 0.903. Two nomograms were created for easier use. CONCLUSION: Clinically relevant fistula can be predicted using simple laboratory and clinical parameters. Not serum amylase, but serum lipase is an independent predictor of CR-POPF. Our simple nomograms may help in the identification of patients for early postoperative interventions.

[Results of the Dry Eye Research Grant Award 2016]. / Ergebnisse der Sicca-Forschungsförderung 2016.

The Sicca-Förderpreis (Dry Eye Award) supports the development of scientific research on the pathogenesis, diagnostics, and treatment of dry eye and ocular surface diseases. It is awarded after a limited call for proposals in German-speaking countries, written application and selection of the award winner after evaluation by a jury of ophthalmologists working in basic and clinical science. In this article examples of the results of funded projects of the Sicca-Förderpreis 2016 are cursorily described, which were presented at the Ophthalmological Academy of Germany 2019 (Augenärztliche Akademie Deutschland 2019) and therefore provide an insight into current scientific developments. The role of muscarinic receptors and those of urea in the pathogenesis of dry eye as well as the (missing) correlation of tear film stability, viscosity and surface tension are highlighted. A project on the early detection of ocular involvement in graft versus host disease and the idea of treating meibomian gland dysfunction with eyelid surgery techniques are also groundbreaking. The outlined projects represent the potential for further substantial developments in the understanding, diagnostics and treatment of dry eye; however, their long-term clinical relevance still needs to be established.

Human surface anatomy terminology for dermatology: a Delphi consensus from the International Skin Imaging Collaboration.

BACKGROUND: There is no internationally vetted set of anatomic terms to describe human surface anatomy. OBJECTIVE: To establish expert consensus on a standardized set of terms that describe clinically relevant human surface anatomy. METHODS: We conducted a Delphi consensus on surface anatomy terminology between July 2017 and July 2019. The initial survey included 385 anatomic terms, organized in seven levels of hierarchy. If agreement exceeded the 75% established threshold, the term was considered 'accepted' and included in the final list. Terms added by the participants were passed on to the next round of consensus. Terms with <75% agreement were included in subsequent surveys along with alternative terms proposed by participants until agreement was reached on all terms. RESULTS: The Delphi included 21 participants. We found consensus (≥75% agreement) on 361/385 (93.8%) terms and eliminated one term in the first round. Of 49 new terms suggested by participants, 45 were added via consensus. To adjust for a recently published International Classification of Diseases-Surface Topography list of terms, a third survey including 111 discrepant terms was sent to participants. Finally, a total of 513 terms reached agreement via the Delphi method. CONCLUSIONS: We have established a set of 513 clinically relevant terms for denoting human surface anatomy, towards the use of standardized terminology in dermatologic documentation.

Dermatoscopic features of thin (≤2 mm Breslow thickness) vs. thick (>2 mm Breslow thickness) nodular melanoma and predictors of nodular melanoma versus nodular non-melanoma tumours: a multicentric collaborative study by the International Dermoscopy Society.

BACKGROUND: Thin nodular melanoma (NM) often lacks conspicuous melanoma-specific dermatoscopic criteria and escapes clinical detection until it progresses to a thicker and more advanced tumour. OBJECTIVE: To investigate the dermatoscopic morphology of thin (≤2 mm Breslow thickness) vs. thick (>2 mm) NM and to identify dermatoscopic predictors of its differential diagnosis from other nodular tumours. METHODS: Retrospective, morphological case-control study, conducted on behalf of the International Dermoscopy Society. Dermatoscopic images of NM and other nodular tumours from 19 skin cancer centres worldwide were collected and analysed. RESULTS: Overall, 254 tumours were collected (69 NM of Breslow thickness ≤2 mm, 96 NM >2 mm and 89 non-melanoma nodular lesions). Light brown coloration (50.7%) and irregular brown dots/globules (42.0%) were most frequently observed in ≤2 mm NMs. Multivariate analysis revealed that dotted vessels (3.4-fold), white shiny streaks (2.9-fold) and irregular blue structureless area (2.4-fold) were predictors for thinner NM compared to non-melanoma nodular tumours. Overall, irregular blue structureless area (3.4-fold), dotted vessels (4.6-fold) and serpentine vessels (1.9-fold) were predictors of all NM compared to non-melanoma nodular lesions. LIMITATIONS: Absence of a centralized, consensus pathology review and cases selected form tertiary centres maybe not reflecting the broader community. CONCLUSIONS: Our study sheds light into the dermatoscopic morphology of thin NM in comparison to thicker NM and could provide useful clues for its differential diagnosis from other non-melanoma nodular tumours.

Standardization of dermoscopic terminology and basic dermoscopic parameters to evaluate in general dermatology (non-neoplastic dermatoses): an expert consensus on behalf of the International Dermoscopy Society.

BACKGROUND: Over the last few years, several articles on dermoscopy of non-neoplastic dermatoses have been published, yet there is poor consistency in the terminology among different studies. OBJECTIVES: We aimed to standardize the dermoscopic terminology and identify basic parameters to evaluate in non-neoplastic dermatoses through an expert consensus. METHODS: The modified Delphi method was followed, with two phases: (i) identification of a list of possible items based on a systematic literature review and (ii) selection of parameters by a panel of experts through a three-step iterative procedure (blinded e-mail interaction in rounds 1 and 3 and a face-to-face meeting in round 2). Initial panellists were recruited via e-mail from all over the world based on their expertise on dermoscopy of non-neoplastic dermatoses. RESULTS: Twenty-four international experts took part in all rounds of the consensus and 13 further international participants were also involved in round 2. Five standardized basic parameters were identified: (i) vessels (including morphology and distribution); (ii) scales (including colour and distribution); (iii) follicular findings; (iv) 'other structures' (including colour and morphology); and (v) 'specific clues'. For each of them, possible variables were selected, with a total of 31 different subitems reaching agreement at the end of the consensus (all of the 29 proposed initially plus two more added in the course of the consensus procedure). CONCLUSIONS: This expert consensus provides a set of standardized basic dermoscopic parameters to follow when evaluating inflammatory, infiltrative and infectious dermatoses. This tool, if adopted by clinicians and researchers in this field, is likely to enhance the reproducibility and comparability of existing and future research findings and uniformly expand the universal knowledge on dermoscopy in general dermatology. What's already known about this topic? Over the last few years, several papers have been published attempting to describe the dermoscopic features of non-neoplastic dermatoses, yet there is poor consistency in the terminology among different studies. What does this study add? The present expert consensus provides a set of standardized basic dermoscopic parameters to follow when evaluating inflammatory, infiltrative and infectious dermatoses. This consensus should enhance the reproducibility and comparability of existing and future research findings and uniformly expand the universal knowledge on dermoscopy in general dermatology.

Efficacy of antibiotic prophylaxis in intraoral bone grafting procedures: a systematic review and meta-analysis.

The purpose of this systematic review was to investigate the efficacy of antibiotic prophylaxis (AP) in intraoral bone grafting procedures for the prevention of postoperative infection (POI). Electronic and manual searches were conducted to identify randomized controlled trials (RCTs). The primary outcome assessed was receptor site POI; secondary outcomes assessed included donor site POI, wound dehiscence, pain, graft failure, need for re-grafting, adverse events, patient satisfaction, and quality of life. A random-effects meta-analysis was conducted to obtain risk ratios of dichotomous data. Four RCTs were selected: one examined AP versus placebo and concluded that there was an increased risk of POI without AP; three examined comparative antibiotic regimens and found no statistically significant difference between them. A meta-analysis of prophylactic regimens, including data from the two RCTs that compared preoperative AP to perioperative AP, indicated no statistically significant difference in POI outcomes (P= 0.94, risk ratio 0.94). It was not possible to conduct further meta-analyses for POIs or for any secondary outcomes due to insufficient published data. The risk of bias assessment indicated an overall unclear risk of bias. On the basis of the present review, there is insufficient evidence to support or refute AP for the prevention of POIs in intraoral bone graft placement procedures.

Use of small intestinal submucosa for corporal body grafting in cases of epispadias and epispadias/exstrophy complex.

BACKGROUND: Male epispadias is a rare congenital urogenital anomaly in which the meatus is ectopically located along the dorsal midline of the penile shaft. In cases associated with severe curvature, functional and cosmetic outcomes could be accomplished by lengthening the shorter dorsal surface with the use of corporal grafting. Various graft materials have been used in the past for hypospadias repair including tunica vaginalis, dermis, and small intestinal submucosa (SIS). The use of SIS grafting for corporoplasty during epispadias repair has rarely been described in the literature. OBJECTIVE: To report the experience in the management of dorsal corporal body grafting using SIS in children with severe penile curvature due to epispadias. STUDY DESIGN: The authors retrospectively reviewed the charts of all patients with epispadias or bladder exstrophy/epispadias complex and severe dorsal chordee (>40°) who underwent epispadias repair with single-layer SIS for corporal body grafting. Clinical variables, surgical technique, and outcomes were analyzed. RESULTS: A total of nine consecutive patients underwent staged epispadias repair with dorsal corporal single-layer SIS grafting (summary figure). Of these, four (44.4%) had primary penopubic epispadias, one (11.1%) had mid-shaft epispadias, and four (44.4%) had bladder exstrophy/epispadias complex. The mean age at surgery was 13.4 ± 6 months. After phalloplasty with SIS grafting, there were no reported complications related to the graft during the post-operative period or follow-up visits. DISCUSSION: Although traditional techniques for epispadias repair allow some degree of corporal lengthening, they also result in abrupt medial rotation of the corporal bodies leading to torqueing and potential unsatisfactory cosmetic results. In contrast, the authors use single-layer SIS for corporal body grafting, and this study technique results in a more gradual inward rotation thus allowing more anatomical accuracy. Furthermore, an advantage of the use of SIS over other grafting materials is that there is no need to harvest an autologous graft such as tunica vaginalis or dermis. CONCLUSION: Epispadias repair using single-layer SIS corporal body grafting is an effective, safe, and feasible method, which provides satisfactory cosmesis and correction of dorsal curvature in congenital epispadias in children. Furthermore, a more normal penis appearance, without a decrease in the corporal length or diameter, is achieved with this technique.

[Advanced medical post within hospitals as possible tactical instrument for handling mass casualty incidents]. / Der Behandlungsplatz innerhalb eines Krankenhauses als mögliches taktisches Werkzeug zur Bewältigung eines Massenanfalls von Patienten.

BACKGROUND: An important instrument for handling mass casualty incidents in preclinical settings is the use of an advanced medical post. In certain circumstances, however, the establishment of such an advanced medical post on or close to the incident site is impossible. Terrorist attacks are a prime example for this. The highest priority for hospitals during mass casualty incidents is to adjust the treatment capacity to the acute rise in demand and to sustain its functionality throughout the duration of the incident. By establishing an advanced medical post within hospitals during certain types of mass casualty incidents these aims could potentially be accomplished. AIMS: The aims of this pilot study were to test the practicability of the establishment of an advanced medical post within a university hospital and to identify potential problems. The results provide the foundation of a generalized concept, which will then be integrated into the hospital emergency plans. METHODS: After the formation of a multiprofessional expert committee, different areas within the hospital were evaluated based on spatial and tactical considerations. Predefined questions were assessed and harmonized with respect to organization, vehicle management, communication, leadership and patient transport through the means of a practice run. RESULTS: The establishment and operation of an advanced medical post within the hospital were easily possible. The consequent deployment of section leaders enabled the smooth coordination of transport and an unobstructed simulated patient flow. The management of the treatment area by a senior emergency physician and a senior emergency medical service officer in close cooperation with the operational hospital lead proved to be a useful concept. Technical problems with communication within the hospital were resolved by using wireless phones and the installation of a digital radio repeater. DISCUSSION: During acute scenarios with only short prior notice, the authors prefer concepts that supplement the normal hospital operation through additional staff and material. In circumstances with prior notice of more than 60 min an advanced intrahospital advanced medical post, staffed by civil protection units, could be a concept that enables the absorption of the first patient arrivals within the first hour of a mass casualty incident without disturbing the functionality of hospitals to any great extent. Further practice runs are, however, necessary to further develop and adjust this concept to real-life circumstances.

[Dermoscopy in special locations : Nails, acral skin, face, and mucosa]. / Dermatoskopie in Sonderlokalisationen : Nägel, akrale Haut, Gesicht und Mukosa.

The use of dermoscopy by dermatologists across Europe has become a standard examination for benign and malignant skin lesions and increasingly also for inflammatory skin diseases. However, based on the experience of the authors from numerous dermoscopy courses, knowledge about important dermoscopic features in special locations such as mucosa or nails is often limited. This may be explained by (1) a different anatomy of the skin and its adnexa in special locations in comparison to the remaining integument, (2) difficult technical access to special locations with a dermatoscope, and (3) a rather low incidence of malignant skin neoplasms in areas of special locations (with the exception of facial skin/scalp). This article aims at explaining dermoscopic characteristics and features of important benign and malignant lesions of nails, acral skin, face, and mucosa.

Mathematical modelling of glob-driven tear film breakup.

Evaporation is a recognized contributor to tear film thinning and tear breakup (TBU). Recently, a different type of TBU is observed, where TBU happens under or around a thick area of lipid within a second after a blink. The thick lipid corresponds to a glob. Evaporation alone is too slow to offer a complete explanation of this breakup. It has been argued that the major reason of this rapid tear film thinning is divergent flow driven by a lower surface tension of the glob (via the Marangoni effect). We examine the glob-driven TBU hypothesis in a 1D streak model and axisymmetric spot model. In the model, the streak or spot glob has a localized high surfactant concentration, which is assumed to lower the tear/air surface tension and also to have a fixed size. Both streak and spot models show that the Marangoni effect can lead to strong tangential flow away from the glob and may cause TBU. The models predict that smaller globs or thinner films will decrease TBU time (TBUT). TBU is located underneath small globs, but may occur outside larger globs. In addition to tangential flow, evaporation can also contribute to TBU. This study provides insights about mechanism of rapid thinning and TBU which occurs very rapidly after a blink and how the properties of the globs affect the TBUT.

Dynamics of Fluorescent Imaging for Rapid Tear Thinning.

A previous mathematical model has successfully simulated the rapid tear thinning caused by glob (thicker lipid) in the lipid layer. It captured a fast spreading of polar lipid and a corresponding strong tangential flow in the aqueous layer. With the simulated strong tangential flow, we now extend the model by adding equations for conservation of solutes, for osmolarity and fluorescein, in order to study their dynamics. We then compare our computed results for the resulting intensity distribution with fluorescence experiments on the tear film. We conclude that in rapid thinning, the fluorescent intensity can linearly approximate the tear film thickness well, when the initial fluorescein concentration is small. Thus, a dilute fluorescein is recommended for visualizing the rapid tear thinning during fluorescent imaging.

Dermoscopy and the diagnosis of primary cutaneous B-cell lymphoma.

BACKGROUND: Primary cutaneous B-cell lymphomas (PCBCLs) are frequently misdiagnosed, and a biopsy is needed to attain the correct diagnosis. OBJECTIVE: To characterize the dermoscopic features of PCBCL. METHODS: In this retrospective observational study, we analysed the pathology reports of 172 newly diagnosed PCBCL for the initial clinical differential diagnosis. The dermoscopic images of 58 PCBCL were evaluated for dermoscopic features. Two dermoscopy experts, who were blinded to the diagnosis and the study objective, evaluated images from 17 cases for a dermoscopic differential diagnosis. RESULTS: Of 172 biopsy-proven PCBCL lesions, cutaneous lymphoma was suspected by the clinician in 16.3%; the leading diagnosis was basal cell carcinoma in 17.4%, and other skin neoplasms in 21%. Studying 58 PCBCL dermoscopic images, we most frequently identified salmon-coloured background/area (79.3%) and prominent blood vessels (77.6%), mostly of serpentine (linear-irregular) morphology (67.2%). Dermoscopic features did not differ significantly by subtype or location. Blinded evaluation by dermoscopy experts raised a wide differential diagnosis including PCBCL, arthropod bite, basal cell carcinoma, amelanotic melanoma and scar/keloid. CONCLUSIONS: Two dermoscopic features, salmon-coloured area/background and serpentine vessels, are frequently seen in PCBCL lesions. These characteristic dermoscopic features, although not specific, can suggest a possible diagnosis of PCBCL.

Bladder exstrophy closure in the newborn period with external pelvic fixation performed without osteotomy: A preliminary report.

BACKGROUND: Successful primary bladder closure is the most crucial element for urinary continence in patients with classic bladder exstrophy (CBE). In the newborn period, bladder closure can be performed in the first 48 h without pelvic osteotomy or external fixation, but requires postoperative lower extremity immobilization (i.e., spica cast, Bryant's or Buck's traction). OBJECTIVE: To present a novel surgical approach for primary bladder closure for CBE using two-pin external fixation without pelvic osteotomy, and without postoperative lower extremity immobilization. STUDY DESIGN: A retrospective chart review of patients with CBE was performed at the current institution from 2000 to 2016, including all primary bladder closures with external fixation and without osteotomy or lower extremity immobilization. Patients were discharged with the external fixator in place, which was later removed in clinic. Baseline clinical and demographic variables, and follow-up data were recorded. RESULTS: Thirteen patients were analyzed; eight (61.5%) were male. Pre-operative intersymphysial distance was 3.68 ± 1.0 cm (2.0-5.0). Mean follow-up was 56.8 ± 40.3 months (10-131). One patient had a partial bladder neck dehiscence, due to pin displacement on postoperative day 1: he had the lowest gestational age of 34 weeks (Summary table). DISCUSSION: This approach used external fixation to bring the pubic bones together intra-operatively, and to decrease the tension in closing the pelvic ring and abdominal wall without osteotomy. External fixation with osteotomy and long-term immobilization, or using a spica cast without osteotomy offered the added advantage of improved wound care, due to lack of lower limb immobilization, less patient discomfort, and facilitation of mother/caregiver and newborn bonding. CONCLUSION: The two-pin external fixator without osteotomy as an adjunct to primary bladder closure in CBE patients was technically feasible. At the current institution this approach had an equivalent success rate to previous reports in the literature for primary bladder closure, decreased the length of hospital stay, and precluded the need for lower extremity immobilization. Early data for bladder capacity were encouraging.
