[Ethical Considerations of Including Minors in Clinical Trials Using the Example of the Indicated Prevention of Psychotic Disorders]. / Minderjährige in klinischen Prüfungen: Ethische Abwägungen ihres Einbezugs am Beispiel der indizierten Prävention psychotischer Erkrankungen.

Ethical Considerations of Including Minors in Clinical Trials Using the Example of the Indicated Prevention of Psychotic Disorders Abstract: As a vulnerable group, minors require special protection in studies. For this reason, researchers are often reluctant to initiate studies, and ethics committees are reluctant to authorize such studies. This often excludes minors from participating in clinical studies. This exclusion can lead to researchers and clinicians receiving only incomplete data or having to rely on adult-based findings in the treatment of minors. Using the example of the study "Computer-Assisted Risk Evaluation in the Early Detection of Psychotic Disorders" (CARE), which was conducted as an 'other clinical investigation' according to the Medical Device Regulation, we present a line of argumentation for the inclusion of minors which weighs the ethical principles of nonmaleficence (especially regarding possible stigmatization), beneficence, autonomy, and fairness. We show the necessity of including minors based on the development-specific differences in diagnostics and early intervention. Further, we present specific protective measures. This argumentation can also be transferred to other disorders with the onset in childhood and adolescence and thus help to avoid excluding minors from appropriate evidence-based care because of insufficient studies.

Can you trust this source? Advice taking in borderline personality disorder.

Research suggests that patients with borderline personality disorder (BPD) share a range of cognitive biases with patients with psychosis. As the disorder often manifests in dysfunctional social interactions, we assumed associated reasoning styles would be exaggerated in a social setting. For the present study, we applied the Judge-Advisor System by asking participants to provide initial estimates of a person's age and presumed hostility based on a portrait photo. Afterwards, we presented additional cues/advice in the form of responses by anonymous previous respondents. Participants could revise their estimate, seek additional advice, or make a decision. Contrary to our preregistered hypothesis, patients with BPD (n = 38) performed similarly to healthy controls (n = 30). Patients sought the same number of pieces of advice, were equally confident, and used advice in similar ways to revise their estimates. Thus, patients with BPD did trust advice. However, patients gave higher hostility ratings to the portrayed persons. In conclusion, patients with BPD showed no cognitive biases in seeking, evaluating, and integrating socially provided information. While the study implies emotional rather than cognitive biases in the disorder, cognitive biases may still prove to be useful treatment targets in order to encourage delaying and reflecting on extreme emotional responses in social interactions.

Near-infrared fluorescence tattooing: a new approach for endoscopic marking of tumors in minimally invasive colorectal surgery using a persistent near-infrared marker.

INTRODUCTION: Intraoperative accurate localization of tumors in the lower gastrointestinal tract is essential to ensure oncologic radicality. In minimally invasive colon surgery, tactile identification of tumors is challenging due to diminished or absent haptics. In clinical practice, preoperative endoscopic application of a blue dye (ink) to the tumor site has become the standard for marking and identification of tumors in the colon. However, this method has the major limitation that accidental intraperitoneal spillage of the dye can significantly complicate the identification of anatomical structures and surgical planes. In this work, we describe a new approach of NIR fluorescent tattooing using a near-infrared (NIR) fluorescent marker instead of a blue dye (ink) for endoscopic tattooing. METHODS: AFS81x is a newly developed NIR fluorescent marker. In an experimental study with four domestic pigs, the newly developed NIR fluorescent marker (AFS81x) was used for endoscopic tattooing of the colon. 7-12 endoscopic submucosal injections of AFS81x were placed per animal in the colon. On day 0, day 1, and day 10 after endoscopic tattooing with AFS81x, the visualization of the fluorescent markings in the colon was evaluated during laparoscopic surgery by two surgeons and photographically documented. RESULTS: The detection rate of the NIR fluorescent tattoos at day 0, day 1, and day 10 after endoscopic tattooing was 100%. Recognizability of anatomical structures during laparoscopy was not affected in any of the markings, as the markings were not visible in the white light channel of the laparoscope, but only in the NIR channel or in the overlay of the white light and the NIR channel of the laparoscope. The brightness, the sharpness, and size of the endoscopic tattoos did not change significantly on day 1 and day 10, but remained almost identical compared to day 0. CONCLUSION: The new approach of endoscopic NIR fluorescence tattooing using the newly developed NIR fluorescence marker AFS81x enables stable marking of colonic sites over a long period of at least 10 days without compromising the recognizability of anatomical structures and surgical planes in any way.

Disaggregating the dementia monolith: An analysis of variation in Medicare costs and use by dementia subtype.

IMPORTANCE: With an aging population, it is necessary to systematically examine variation in costs and use of Medicare services by dementia subtype. We provide the first national estimates for dementia by subtype, and the respective Medicare costs and use. METHODS: We analyzed Medicare fee-for-service (FFS) claims from 2017 through 2019. The sample included 41 million beneficiaries: 727,700 beneficiaries with a new dementia diagnosis in 2017. We calculated descriptive statistics and conducted generalized linear regression models by subtype of dementia. RESULTS: Annual Medicare costs for beneficiaries with dementia ranged from $22,840 for frontotemporal dementia to $44,896 for vascular dementia compared to $9,034 for beneficiaries without dementia. Comparing beneficiaries across dementia subtypes, the greatest differences were in the use of home health and hospice care. CONCLUSIONS: These analyses demonstrate substantial heterogeneity across dementia subtypes, which will be important in developing models of care that improve value for people with dementia.

Evaluation of an SPF50 Sunscreen Containing Photolyase and Antioxidants for its Anti-Photoaging Properties and Photoprotection.

BACKGROUND: Background: Skin exposure to ultraviolet radiation (UVR) causes DNA damage, which can lead to mutagenesis, carcinogenesis, cellular death, and photoaging. Signs of photoaging include wrinkling, erythema, skin laxity, uneven skin texture, and hyperpigmentation. Photolyase is an exogenous DNA repair enzyme that can restore DNA integrity when applied topically to human skin. Antioxidants also play a key role in reducing UVR-associated molecular damage. OBJECTIVE: To assess the efficacy and safety of a tinted mineral-based sunscreen containing 10.7% zinc oxide (SPF50) with the active ingredients photolyase, antioxidants (Peptide Q10), and peptides in both protecting and repairing signs of photoaging. METHODS: In an open-label, single-center, 12-week study, patients aged 35–55 years and Fitzpatrick skin phototypes II–IV applied the sunscreen daily for 84 days. VISIA photography was performed at baseline as well as 6- and 12-week follow-ups. At each visit, the investigator and subject evaluated clinical photoaging parameters including overall photodamage, fine lines/wrinkles, coarse lines/wrinkles, skin tone evenness, tactile roughness, and radiance. RESULTS: The Investigator Global Aesthetic Improvement Scale (IGAIS) found that 63% of patients showed improvement at week 6 and 81% at week 12. The Subject Global Aesthetic Improvement Scale (SGAIS) showed 58% and 62.5% of patients reported the appearance of their skin was improved at week 6 and 12, respectively. Overall, there was a statistically significant improvement in skin radiance as well as improvement in overall facial aesthetics reported by both investigators and subjects. CONCLUSION: This tinted mineral based SPF50 sunscreen containing photolyase, antioxidants, and peptides is effective at repairing some clinical signs of photoaging and is well-tolerated for daily use.

A Prospective, Randomized, Double-Blind, Vehicle-Controlled Study Evaluating the Efficacy, Safety, and Patient Satisfaction of Tretinoin 0.05% Lotion for Chest Rejuvenation.

BACKGROUND: There is increasing interest in non-invasive options for chest rejuvenation with minimal to no downtime. Topical retinoids have long been used to correct photoaging due to their ability to promote epidermal hyperplasia, matrix metalloproteinase inhibition, collagen synthesis, and dispersion of melanin granules. Topical retinoid use is often limited by the ensuing irritation that occurs with initial use and resolves after about one month. Vehicle of delivery is a key factor to consider in order to minimize irritation and increase patient satisfaction. Micronized tretinoin 0.05% suspended in a polymer emulsion of hydrating ingredients (sodium hyaluronate, soluble collagen, and glycerin) is designed to aid in reducing irritation while ensuring uniform drug delivery. OBJECTIVE: The primary objective of our study is to evaluate the safety, efficacy, and patient satisfaction of tretinoin 0.05% lotion for nonprocedural photorejuvenation of the chest. RESULTS: A total of 29 patients completed the trial, average age of 54.42 years (37-66 years old), Fitzpatrick II-IV skin types. Both the active and vehicle groups showed 30-40% improvement at day 180 according to the blinded evaluator mean percent improvement. Investigator global aesthetic improvement scale also trended towards improvement in both groups, with most patients exhibiting "improvement." Both the active and vehicle groups showed a significant change over time according to the nine-point photodamage and wrinkling scale, P<0.001 and P=0.007 (single factor ANOVA), respectively. The Fabi Bolton Wrinkle Scale also demonstrated improvement from screening to day 180; however, there was no statistical significance at any time point. At day 90, the active group had statistically significantly more erythema than the vehicle group (P<0.001), although both groups were only mild. At day 180, erythema decreased in both groups with the active group being similar to the vehicle group, 0.50±0.73 versus 0.09±0.30, respectively. Subjects in both the active and vehicle groups were equally satisfied at day 180, (2.38±1.15 in the active group versus 2.30±1.16 in the treatment group), with most subjects feeling "satisfied" with their results by day 180. This was also reflected in the subject global aesthetic improvement scale with most subjects noting noticeable improvement in the appearance of their chest from day 30 to day 180. CONCLUSION: Tretinoin 0.05% lotion delivered in a proprietary blend of hydrating ingredients offers a safe and efficacious option that has minimal downtime for patients seeking non-procedural photo-rejuvenation of the chest. The proprietary vehicle, containing hyaluronic acid, glycerin, and collagen, was crucial in minimizing irritation and producing at least a one-point improvement according to the 9 point photodamage scale and 30-40% improvement in photodamage as noted by the blinded evaluator percent improvement score in both the vehicle and active groups.

Autoantibody-associated psychiatric syndromes in children: link to adult psychiatry.

Studies show that psychiatric symptoms in adults and children are sometimes associated with serum neural autoantibodies. The significance of serum neural autoantibodies associated with psychiatric symptoms in children remains often unclear, but might be relevant for the extent and occurrence of psychiatric disease manifestation in later life, as well as therapy and outcome. For this narrative review, we sought articles listed in PubMed and published between 1988 and 2020 addressing the maternal-fetal transfer of neural autoantibodies and psychiatric disorders associated with serum neural autoantibodies. We identified six major subgroups of psychiatric disorders in children that are associated with serum neural autoantibodies: patients with attentional deficit hyperactivity disorder, autism spectrum disorder, obsessive compulsive disorder, Gilles de la Tourette syndrome, psychosis and catatonia. Furthermore, we summarized study findings from maternal-fetal transfer of Contactin-associated protein-like 2, N-methyl-D-aspartate receptor and fetal brain autoantibodies associated with behavioral effects in animals and humans. We hypothesize that the maternal transfer of serum neuronal autoantibodies during or after birth could result (1) in the ignition of an autoimmune-mediated inflammation having neurodevelopmental consequences for their children (autoimmune-priming-attack hypothesis) and (2) has a potential impact on the later manifestation of psychiatric disorders. Through this narrative review, we propose a diagnostic pathway for the clinical diagnosis of a potentially autoimmune origin of psychiatric symptoms in children while considering recent guidelines.

Safety and Efficacy of a Novel 730 nm Picosecond Titanium Sapphire Laser for the Treatment of Benign Pigmented Lesions.

BACKGROUND AND OBJECTIVES: Picosecond lasers in dermatology were originally focused on optimizing the removal of unwanted tattoos. Subsequent advances in this technology have expanded its clinical indications to include treatment of benign pigmented lesions, photodamage, melasma, and scar revision. In this retrospective review, we evaluate a novel 730 nm picosecond titanium sapphire laser in treating benign pigmented lesions. STUDY DESIGN/MATERIALS AND METHODS: This is a retrospective review of all patients who presented to our institution between December 2019 and March 2020 for treatment of their benign pigmented lesions with a 730 nm picosecond titanium sapphire laser. All Fitzpatrick skin types (I-VI) were included. Absolute and relative evaluations were conducted by two blinded board-certified dermatologists using high-resolution photographic images. RESULTS: Twenty-two of 64 patients satisfied inclusion and exclusion criteria. Patients received 1.1 ± 0.3 treatment sessions. The absolute average pigmentation score prior to treatment was 2.04 ± 0.7 versus 1.39 ± 0.6 after treatment (P < 0.05). Improvement in pigmentation was observed in 86% of the patients, while 3% had no improvement and 11% had worsening of pigmentation. No other adverse events were observed. Downtime consisted of 1-2 days of mild edema and erythema followed by 3-5 days of mild pigment darkening and superficial crust. CONCLUSION: The novel 730 nm picosecond titanium sapphire laser is a safe and effective treatment for benign pigmented lesions. Future prospective randomized control studies would be beneficial to further clarify its role in the treatment of benign pigmentation. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.

Prospective Clinical Trial of the Latest Generation of Noninvasive Monopolar Radiofrequency for the Treatment of Facial and Upper Neck Skin Laxity.

BACKGROUND: Aging of the face and upper neck is a complex process characterized by loss of collagen and elastic fibers, resulting in clinical skin laxity. Noninvasive interventions such as monopolar capacitively coupled radiofrequency (MRF) have gained popularity, offering a safer and more convenient alternative to traditional surgical face lift. The latest MRF device features larger tips, vibration, cooling, and impedance matching. OBJECTIVE: We performed the first open-label clinical trial, measuring the efficacy, safety, and patient satisfaction of this device for noninvasive lifting and tightening of the face and upper neck. MATERIALS AND METHODS: Forty subjects 30 to 60 years of age with mild/moderate skin laxity of the face and upper neck were enrolled. After pretreatment with ketorolac 60 mg intramuscular injection, subjects underwent treatment with MRF. Follow-up evaluations were performed on Days 30, 60, and 180. RESULTS: Our study demonstrated that the newest generation MRF produced statistically significant improvement in skin laxity 6 months post-treatment, especially in the jowls and melolabial folds. According to the Investigator Global Aesthetic Improvement Score, 73% of subjects had improvement at 6 months post-treatment. Subject satisfaction and improvement questionnaires supported these findings. CONCLUSION: Our data coupled with the excellent adverse effect profile validates MRF as an attractive treatment modality for facial and upper neck skin laxity.

Intense Pulsed Light: A Methodical Approach to Understanding Clinical Endpoints.

BACKGROUND: Intense Pulsed Light (IPL) is a non-coherent polychromatic broadband filtered flashlamp that emits light in the spectrum of approximately 400–1200 nm. Its effects on photorejuvenation are well documented. The goal of this study is to help practitioners better conceptualize and fine tune IPL device settings in order to produce the most effective and safest clinical outcome. MATERIALS/METHODS: This was a prospective study testing several filters (515 nm; 560 nm; 590 nm and 530–650; 900–1200 nm vascular filter), fluences, pulse durations, and pulse numbers (ie, multiple sequence pulsing or MSP) with a new IPL system. RESULTS: Post-procedure erythema response was more pronounced with increasing fluence, decreasing wavelength, fewer pulses and shorter pulse duration. The exception was the 515 nm filter with regard to pulse duration, which was observed to have a more pronounced response with longer pulse durations. The overall clinical outcome at the 4-week follow-up visit demonstrated greatest improvement in erythema and pigmentation using the 515 nm filter on a Fitzpatrick Skin Type III individual. CONCLUSION: Greatest clinical endpoint response at 4-week follow-up was observed with more robust initial responses. This was most apparent at higher fluence levels and fewer pulse counts. However, when the IPL is pushed to aggressive parameters, there is risk of hypopigmentation and hair loss as seen in this case study. Skin type is an important consideration when using IPL and MSP adds to its safety profile. J Drugs Dermatol. 2021;20(2):203-207. doi:10.36849/JDD.5638.

Single-Center, Prospective, Double-Blind, Evaluator-Blind, non-Randomized, Vehicle-Controlled Trial With a 1927 Nm Non-Ablative Fractionated Laser and Topical 0.05% Tretinoin Lotion for Facial Dyspigmentation and Photodamage.

BACKGROUND: Dyspigmentation and photodamage are common concerns in patients who seek aesthetic consultation. A number of treatment modalities have been utilized to address this issue. 1927 nm thulium fiber laser is a fractionated non-ablative laser that has been shown to be safe and effective in treatment of photoaging. Topical retinoids have been used for over two decades for photoaging to promote epidermal hyperplasia and collagen synthesis and to decrease melanin production. There has been lack of data to support the combination of topical retinoids with laser treatments in the management of facial dyspigmentation and photodamage. OBJECTIVE: The primary objective of this study is to evaluate the benefits and subject satisfaction resulting from use of a 1927 nm thulium fiber laser with and without 0.05% tretinoin lotion for facial dyspigmentation and photodamage. RESULTS: Both groups showed a significant change in Investigator Assessed Overall Hyperpigmentation and Investigator Assessed Overall Photodamage over time (P<0.001). No statistically significant differences were seen between groups at any time point as measured by investigator reported and subject reported efficacy scales except for Subject Global Aesthetic Improvement Scale and Subject Satisfaction at 30 days after laser treatment, at which patients who received 0.05% tretinoin lotion reported a lower level of improvement (2.8 ± 0.86 in the treatment group vs 2 ± 0.85 in the vehicle group, P=0.009) and lower patient satisfaction when compared to the vehicle group (2.87 ± 1.55 in the treatment groups vs 1.53 ± 0.64 in the vehicle group, P=0.001). CONCLUSION: In our study, patients tolerated the combination of 1927 nm thulium fiber laser and 0.05% tretinoin lotion well. Both groups resulted in significant reduction of hyperpigmentation and photodamage. Subject satisfaction and perceived improvement were temporarily lower at 30 days only when, combining 0.05% tretinoin lotion with 1927 nm thulium fiber laser. Future studies are needed to investigate the impact on efficacy when combining laser procedures with a longer duration of use or a higher concentration of topical tretinoin.

Msl1-mediated dimerization of the dosage compensation complex is essential for male X-chromosome regulation in Drosophila.

The Male-Specific Lethal (MSL) complex regulates dosage compensation of the male X chromosome in Drosophila. Here, we report the crystal structure of its MSL1/MSL2 core, where two MSL2 subunits bind to a dimer formed by two molecules of MSL1. Analysis of structure-based mutants revealed that MSL2 can only interact with the MSL1 dimer, but MSL1 dimerization is MSL2 independent. We show that Msl1 is a substrate for Msl2 E3 ubiquitin ligase activity. ChIP experiments revealed that Msl1 dimerization is essential for targeting and spreading of the MSL complex on X-linked genes; however, Msl1 binding to promoters of male and female cells is independent of the dimer status and other MSL proteins. Finally, we show that loss of Msl1 dimerization leads to male-specific lethality. We propose that Msl1-mediated dimerization of the entire MSL complex is required for Msl2 binding, X chromosome recognition, and spreading along the X chromosome.

Evaluation of Long-Term Outcome and Patient Satisfaction Results After Tumescent Liposuction.

BACKGROUND: Liposuction is one of the most common cosmetic surgery procedures around the world. Tumescent liposuction using local anesthesia has been shown to be the safest technique. Few long-term studies of results and satisfaction have been published on tumescent liposuction. OBJECTIVE: To evaluate long-term results and patient satisfaction of tumescent liposuction in a single-center institution. METHODS: Patients (n = 600) who had tumescent liposuction performed in our practice from 2002 to 2014 were contacted through letter, email, or phone to complete a questionnaire survey and in-office follow-up visit regarding their past liposuction procedures. RESULTS: Thirty-two patients (n = 32) completed the patient questionnaire survey and followed up in the office. Surgeon and blinded evaluators saw significant differences in both the neck volume (surgeon evaluator: 2.42 vs. 0.71, p < .01; blinded evaluator: 2.8-1, p = .02) and Investigator Assessment Skin Laxity scales (blinded evaluator: 1.14 vs. 0.77, p < .01 for laxity and 1.33 vs. 0.75, p < .01 for firmness; surgeon evaluator: 1.17 vs. 0.83, p = .01 for laxity and 1.31 vs. 0.83; p < .01 for firmness). The mean follow-up period was 8.9 years overall and 9.9 years for the neck. Overall, 85.7% of the patients would recommend liposuction to their friends and family members. CONCLUSION: Tumescent liposuction is a safe procedure with long-lasting results and high patient satisfaction.

[Diffuse malignant peritoneal mesothelioma (DMPM) - a rare diagnosis]. / Das diffuse maligne peritoneale Mesotheliom (DMPM) ­ eine seltene Diagnose.

Diffuse malignant peritoneal mesothelioma (DMPM) is a rare diagnosis, found more frequently in men than in women. Symptoms are unspecific abdominal disorders making that diagnosis difficult to set. Causes of DMPM are yet to be discovered in entirety. Asbestos exposure is the reason for approximately 7 % of all peritoneal mesotheliomas. Until the evaluation of systematic cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) DMPM was a fatal diagnosis with a median overall survival (OS) of 4-13 months. The prognosis of DMPM dramatically improved with implementation of CRS and HIPEC to an OS of 30-92 month nowadys. CRS and HIPEC were performed in this case.

Nonsurgical Treatments for Infraorbital Rejuvenation: A Review.

BACKGROUND: Tear trough and infraorbital region changes are one of the first signs recognizable aging. This is a common consultation for cosmetic dermatologists and there are many treatment options available. OBJECTIVE: This article provides a review of the anatomy and changes that occur in the infraorbital region as we age. We also suggest the use of the osseous, color, underlying anatomy, laxity, adipose, rhytides (OCULAR) mnemonic to evaluate these changes and review the literature for treatments options. MATERIALS AND METHODS: A literature search was performed through PubMed, using search terms "Tear trough," "Infra-orbital," "Dark-circles," "Lower-Eyelid," and "Midface." RESULTS: Fillers, lasers, radiofrequency devices, chemical peels, various topicals, and botulinum toxin are available non-surgical treatment options discussed in the literature found to significantly improve and rejuvenate the infraorbital region. CONCLUSION: A complete understanding of the anatomy and changes that occur with aging are of most importance when assessing the infraorbital region. Organizing these changes into the OCULAR mnemonic is one way to assess the infraorbital region and achieve optimal rejuvenation.

[Treatment in Adolescent Psychiatry: Results of a Germany-wide Survey]. / Behandlungsangebote der Adoleszenzpsychiatrie ­ Ergebnisse einer deutschlandweiten Erhebung.

INTRODUCTION: The aim of the study was to examine adolescence-specific treatment models throughout Germany, to describe the implementation process of transition psychiatric care and to identify relevant health care problem areas for adolescents with mental disorders. METHODOLOGY: A questionnaire-based cross-sectional survey (N = 26) of hospital-based adolescent psychiatric treatment models was conducted. Service structures, treatment groups and interventions were investigated by the 28-item questionnaire. RESULTS: There is an increase in adolescence-specific hospital-based services in Germany. These are characterized by multi-professional team work in diagnosis and adolescence-specific therapy approaches. Most of the treatment available is for young adults only (>18 years). Some of the services are organized in interdisciplinary cooperation models. Structural deficits in acute and crisis treatment, cross-sectoral cooperation and systematic transition are reported. Conclusions There is growing interest throughout Germany in the development of adolescent psychiatric treatment. Close interdisciplinary cooperation between child and adolescent psychiatry and adult psychiatry is necessary to overcome interface problems with the aim of a successful transition, but has not yet been implemented. Structural problems should be reduced in order to facilitate further development in transition psychiatry.

Neurocognitive Functioning in Alcohol Use Disorder: Cognitive Test Results Do not Tell the Whole Story.

OBJECTIVES: It is textbook knowledge that individuals with alcohol use disorder (AUD) show large neurocognitive deficits. However, these patients display a number of additional impairments (e.g., lack of drive and motivation) that may contribute to poor test results. The impact of these secondary mediators has not been explored systematically. Based on prior findings that low performance motivation, a negative attitude toward cognitive assessment, and momentary symptoms compromise neuropsychological test results in depression, schizophrenia, and obsessive-compulsive disorder, we examined the possibility that impaired test results in AUD partially represent an epiphenomenon. METHODS: Fifteen patients with AUD and 20 matched nonclinical individuals underwent a comprehensive neuropsychological test battery. The neurocognitive assessment was flanked by the Momentary Influences, Attitudes and Motivation Impact on Cognitive Performance Scale (MIAMI), which captures momentary influences affecting performance. RESULTS: Patients with AUD performed worse than nonclinical controls on most test parameters. Group differences achieved a very large effect size for parameters tapping speed and accuracy. Patients with AUD showed deviant scores, particularly on the post version of the MIAMI (retrospective assessment of symptoms and influences during testing) and the total scores. For accuracy, the MIAMI scores represented a partial mediator. For speed, significant group effect sizes were rendered nonsignificant when the MIAMI was taken into account. CONCLUSION: Like other psychiatric patients, patients with AUD show marked neurocognitive impairments that seem to be aggravated by, for example, distraction and lack of effort. This tentatively suggests that performance only partly reflects cortical impairments in areas hosting neurocognitive faculties. Contextual factors deserve greater attention in patients with addiction. The cross-sectional design of our study limits conclusions relating to causality.

Appropriate Testing of Isothiazolinones in Children.

BACKGROUND/OBJECTIVE: The isothiazolinones methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI) are prevalent pediatric contact sensitizers. MI allergic contact dermatitis (ACD) is underreported in the literature. The objective of the current study was to use a database of provider-reported U.S. pediatric patch test cases to evaluate the positive patch test (PPT) prevalence rates of the combined preservative test substrate MCI/MI and of MI alone. METHODS: U.S. pediatric patch test providers in all 50 states who had joined the registry were invited to submit deidentified cases to the database. More than 1100 logged cases in the database were evaluated for PPTs to MCI/MI combination, MCI/MI and MI, and MI alone. RESULTS: Within 1 year of data collection, 96 cases with a PPT for MCI/MI, MCI/MI and MI, and MI alone were identified; 37 of these were positive to MCI/MI, with MI alone not tested or negative, and 39 were positive to MI only, with MCI/MI and MI tested. Fifteen (41%) of the MCI/MI cases were detected using an epicutaneous patch test alone and 22 cases (59%) using comprehensive patch testing. Only one case (3%) of MI alone sensitization was detected using T.R.U.E. plus a supplemental panel of tests; the remaining 38 cases (97%) were detected using comprehensive testing. Testing with only the combined MCI/MI preservative substrate may miss 51% of MI allergies. CONCLUSION: Appropriate testing of isothiazolinones is needed to clarify the true prevalence of sensitization to these allergens and the burden of pediatric ACD. Patch testing for MI alone in addition to MCI/MI combination is warranted in children with recalcitrant dermatitis.

Practice Patterns of Dermatologists in the Pediatric Contact Dermatitis Registry.

BACKGROUND/OBJECTIVES: U.S. adults and children are equally likely to have allergic contact dermatitis. Historically the narrow geographic location of data-reporting providers has quantitatively and qualitatively limited the pediatric contact dermatitis data. The Pediatric Contact Dermatitis Registry was used to evaluate self-identified pediatric patch test providers within the United States with regard to demographic characteristics, geographic location, and practice patterns. METHODS: A wide range of U.S. providers were invited to join the registry by completing a secure online 11-question registration survey. RESULTS: There were 252 respondents from 50 states and the District of Columbia; 28.6% were pediatric dermatologists and members of the Society for Pediatric Dermatology (SPD), and 38% were members of the American Contact Dermatitis Society. The cumulative range of pediatric patch-test evaluations performed each year was 1,726 to 4,613 children. SPD members had a significantly greater likelihood of performing a commercially available patch test (odds ratio 7.14 [95% confidence interval 5.11, 9.97], p < .001) than those who were not SPD members. SPD members also had significantly lower odds of performing North American Contact Dermatitis Group standard tests than nonmembers. CONCLUSIONS: The frequency of patch test evaluations in children is significantly underreported. This study provides insight into the practice patterns of various providers who are patch testing children and makes recommendations for evidence-based modifications regarding these practices. Limitations of the study include survey responder selection bias and small sample size.

[Benign multicystic peritoneal mesothelioma (BMPM) - a surprising differential diagnosis in case of an expected intraabdominal abscess formation]. / Das benigne multizystische peritoneale Mesotheliom (BMPM) ­ Eine überraschende Differenzialdiagnose bei Verdacht auf einen intraabdominellen Abszess.

The benign multicystic peritoneal mesothelioma is a rare disease. Most frequently, young women in reproductive age are affected by this disease. Nevertheless, there are known cases of multicystic peritoneal mesothelioma in male patients. The pathogenesis remains uncertain. Whereas asbestos fibers can cause the development of malignant mesothelioma, the exposure to asbestos particles cannot induce this type of mesothelioma. An inflammatory genesis is discussed as well as the idea of a neoplastic development. Since a high rate of recurrence after surgery is observed, an aggressive surgical treatment is recommended. The complete resection of affected tissue is recently considered to be the therapy of choice. The combination of complete surgical tumor reduction with an intraperitoneal hyperthermic chemotherapy (HIPEC) seems to be promising. Although malignant transformation is detected very rarely a close follow up in centers with high surgical and oncological expertise is recommended.
