Raster-scanning optoacoustic mesoscopy biomarkers for atopic dermatitis skin lesions

Atopic dermatitis (AD) is the most common chronic inflammatory skin disease worldwide. Its severity is assessed using scores that rely on visual observation of the affected body surface area, the morphology of the lesions and subjective symptoms, like pruritus or insomnia. Ideally, such scores should be complemented by objective and accurate measurements of disease severity to standardize disease scoring in routine care and clinical trials. Recently, it was shown that raster-scanning optoacoustic mesoscopy (RSOM) can provide detailed three-dimensional images of skin inflammation processes that capture the most relevant features of their pathology. Moreover, precise RSOM biomarkers of inflammation have been identified for psoriasis. However, the objectivity and validity of such biomarkers in repeated measurements have not yet been assessed for AD. Here, we report the results of a study on the repeatability of RSOM inflammation biomarkers in AD to estimate their precision. Optoacoustic imaging analysis revealed morphological inflammation biomarkers with precision well beyond standard clinical severity metrics. Our findings suggest that optoacoustic mesoscopy may be a good choice for quantitative evaluations of AD that are inaccessible by other methods. This could potentially enable the optimization of disease scoring and drug development.

Increasing the COVID-19 immunization rate through allergy testing

BACKGROUND

Vaccination of the population is required to combat the COVID-19 pandemic. Allergy testing could reduce anxiety towards COVID-19 vaccination and thereby may increase vaccination rate, however, its effectiveness remains unclear.

METHODS

One hundred and thirty prospective real-life patients in need of but not daring to get vaccinated asked for allergy workup for COVID-19 vaccine hypersensitivity in 2021/2022. Characterization of patients, identification of anxieties, decrease of patient's anxiety levels, overall vaccination rate and adverse reactions after vaccination were assessed.

RESULTS

Tested patients were characterized by being female (91.5%) and having a high rate of previous allergies (e.g. to food 55.4%, drugs 54.6%, or previous vaccinations 50%) and dermatological disease (29.2%) but not always had medical contraindications for COVID-19 vaccination. Sixty one patients (49.6%) were highly concerned (4-6, Likert scale 0-6) about vaccination and 47 (37.6%) expressed resolving thoughts about vaccinaion anaphylaxis (3-6, Likert scale 0-6). However only 35 patients (28.5%) were scared of getting COVID-19 within 2 months (4-6, Likert scale 0-6) and only 11 (9%) patients had high expectations of getting COVID-19 (4-6, Likert scale 0-6). Allergy testing significantly (p < 0.01 to p < 0.05 respectively) reduced the median anxiety of allergic symptoms following vaccination: dyspnoea (4.2-3.1), to faint (3.7-2.7), long-term consequences (3.6-2.2), pruritus (3.4-2.6), skin rash (3.3-2.6) and death (3.2-2.6). After allergy testing, most patients (108/122, 88.5%) let themselves be vaccinated within 60 days. Revaccinated patients with previous symptoms experienced a reduction of symptoms (p < 0.05) upon revaccination.

CONCLUSIONS

Patients not daring to get vaccinated have more anxiety towards vaccination than to acquire COVID-19. For those, allergy testing excludes vaccine allergy, and is a tool to increase vaccination willingness and thereby helps to combat vaccination hesitancy.

Chronic nodular prurigo: clinical profile and burden. A European cross-sectional study

BACKGROUND

Chronic nodular prurigo (CNPG) is a condition characterized by chronic itch, a prolonged scratching behaviour and the presence of pruriginous nodules. A comprehensive understanding of this condition, especially regarding its clinical characteristics and impact on quality of life is still lacking.

OBJECTIVES

Aim of this pan-European multicentre cross-sectional study was to establish the clinical profile of CNPG, including its associated burden.

METHODS

Fifteen centres from 12 European countries recruited CNPG patients presenting at the centre or using the centres' own databases. Patients were asked to complete a questionnaire in paper or electronic format. Demography, current co-morbidities, underlying disease, itch intensity, additional sensory symptoms, quality of life, highest burden and emotional experience of itch were assessed.

RESULTS

A total of 509 patients (210 male, median age: 64 years [52; 72]) were enrolled. Of these, 406 reported itch and CNPG lesions in the previous 7 days and qualified to complete the whole questionnaire. We recorded moderate to severe worst itch intensity scores in the previous 24 h. Scores were higher in patients with lower educational levels and those coming from Eastern or Southern Europe. Most patients experience itch often or always (71%) and report that their everyday life is negatively affected (53%). Itch intensity was considered to be the most burdensome aspect of the disease by 49% of the patients, followed by the visibility of skin lesions (21%) and bleeding of lesions (21%). The majority of patients was unaware of an underlying condition contributing to CNPG (64%), while psychiatric diseases were the conditions most often mentioned in association with CNPG (19%).

CONCLUSIONS

This multicentre cross-sectional study shows that itch is the dominant symptom in CNPG and reveals that the profile of the disease is similar throughout Europe.

Position Statement: Linear prurigo is a subtype of chronic prurigo

BACKGROUND

Chronic prurigo (CPG) is a distinct disease characterized by chronic pruritus, history and/or signs of prolonged scratching and multiple pruriginous lesions. It may present with various clinical manifestations, including papules, nodules, plaques or umbilicated lesions. Some patients with chronic pruritus show pruriginous linear and scaring scratch lesions (LSSL) and it is unclear whether these lesions belong to the spectrum of CPG.

OBJECTIVE

To achieve a consensus on the classification of pruriginous LSSL and establish criteria to differentiate them from similar appearing conditions of different nature.

METHODS

Members of the Task Force Pruritus (TFP) of the European Academy of Dermatology and Venereology participated in the consensus conference, discussing representative clinical cases. Using the Delphi method, consensus was reached when ≥75% of members agreed on a statement.

RESULTS

Twenty-one members of the TFP with voting rights participated in the meeting. It was consented that LSSL occurs due to chronic pruritus and prolonged scratching, and share common pathophysiological mechanisms with CPG. LSSL were thus considered as belonging to the spectrum of CPG and the term 'linear prurigo' was chosen to describe this manifestation.

CONCLUSION

Considering linear prurigo as belonging to the spectrum of CPG has important clinical implications, since both the diagnostic and therapeutic approach of these patients should be performed as recommended for CPG. Importantly, linear prurigo should be differentiated from self-inflicted skin lesions as factitious disorders or skin picking syndromes. In the latter, artificial manipulation rather than pruritus itself leads to the development of cutaneous lesions, which can show clinical similarities to linear prurigo.

[Chronic prurigo]

Chronic prurigo is a disease characterized by the presence of chronic pruritus and singular or multiple usually hyperkeratotic symmetrically distributed itchy papules, nodules, and/or plaques. This condition is difficult to treat and leads to a substantial impairment of the quality of life. It may originate from dermatological, systemic, neurological, psychiatric/psychosomatic, multifactorial or unknown conditions causing itch, which lead to prolonged scratching behavior and sensitization mechanisms and ultimately to the development of pruriginous lesions. Thorough diagnostic efforts, including a detailed clinical history and physical examination, as well as targeted complementary examinations should be initiated as soon as possible. The German guideline recommends topical steroids and phototherapy as first-choice options. Pimecrolimus and capsaicin (topical), as well as antihistamines, anticonvulsants, and immunosuppressive drugs (systemic) should be considered as valid alternatives.

Non-union site debridement increased the efficacy of rhBMP-2 in a rodent model

In our study we investigated the influence of debridement on bone healing in a rodent critical size defect model with and without rhBMP-2 in fibrin matrix. A total of 58 male Sprague-Dawley rats underwent a first surgical procedure where a femoral osteotomy was performed. In the single step group the defect remained empty and the specimens were collected 4 weeks later. A silicone spacer was implanted to inhibit bone healing within the defect in all the other groups. At 4 weeks the spacer was removed in a second operation with and without debridement of the bone ends and fibrin matrix alone or combined with 10 μg rhBMP-2 were applied. 4 weeks after the primary operation those specimens were collected. All the specimens were evaluated by μCT scans and histological analysis. Debridement of the defect significantly increased bone volume in the animals treated with rhBMP-2. In the control groups without growth factor application the effect of debridement was not significant concerning the union rate and the bone volume. In our experimental setting surgical debridement of the non-union site particularly promoted bone healing in combination with BMP-2 administration in fibrin matrix.

Characteristics of polytrauma patients between 1992 and 2002: what is changing?

OBJECTIVE

To analyse the characteristics of polytrauma patients and the quality and progress of treatment regimens by an evaluation of a trauma population.

METHODS

The study included all polytrauma patients treated between 1992 and 2002 at a level 1 trauma centre. Data of 501 cases were collected prospectively and analysed retrospectively. The analysis included the demographic data, injury severity, preclinical haemodynamics, intubation rates, incidences of multiorgan failure and adult respiratory distress syndrome, and mortality.

RESULTS

Per year of the study, the average age of patients increased by 0.748 years. Preclinical intubation rates also increased and the number of cases of primary shock decreased. The Injury Severity Score fell on average by 0.59 points per year. There was a significant decrease in multiorgan failure and adult respiratory distress syndrome. The mortality rate remained constant.

CONCLUSIONS

Protracted time of initial rescue, early intubation and good preclinical treatment lead to a reduction of complications during intensive care. The increasing number of elderly patients results in persistently high mortality even with decreasing injury severity.

[Long-term results in the treatment of foot injuries in polytraumatized patients]

INTRODUCTION

The aim of this study was to evaluate the long-term outcome of multiple injured patients with foot injuries. While severity and frequency of multiple injuries could be decreased in the last years, it was not possible to decrease the severity of injuries of the foot and ankle region. These injuries are often not detected and their severity is underestimated in primarily diagnostics what might lead to complaints in the longterm course.

METHODS

The multiple trauma database of the Department of Traumatology of the University of Vienna includes 386 patients from September 1992 to April 2001. 40 (10.4 %) of these patients suffered a fracture or dislocation of foot or ankle. 33 (82.5 %) multiple injured patients with injuries of foot or ankle could be reexamined between April and September 2002 and the longterm outcome of the foot and ankle region could be evaluated objectively and subjectively.

RESULTS

22 (66.7 %) patients were male, 11 (33.3 %) female. The mean age was 34.5 years. 27 (81.8 %) patients still suffered from complaints related to their injured foot and ankle region. After calculation of the AOFAS these complaints were predominantly located in the ankle-hindfoot region. 22 (66.7 %) patients had to limit their sports activity.

DISCUSSION

In our study period an increasing number and severity of injuries of foot or ankle can be shown. Furthermore multiple injured patients with concomitant injuries of foot or ankle show a lower ISS what suggests that these patients might have a higher survival rate and consecutively enter rehabilitation process.

[Polytrauma and air rescue. A retrospective analysis of trauma care in eastern Austria exemplified by an urban trauma center]

OBJECTIVE

The aim of this study was a retrospective analysis of polytraumatized patients who were treated by a helicopter emergency medical service (HEMS) crew. This study was performed to evaluate the level of prehospital care provided for severely injured patients. Special consideration was given to treatment strategies of specific injuries which led to multiple injuries, defined as "polytrauma."

METHODS

From September 1992 to April 2001 data of 386 patients treated in the Department of Traumatology of the University of Vienna were collected. A total of 104 patients (26.9%) were transported by helicopter directly from the accident scene. This collective was analyzed demographically; relevant prehospital data such as therapeutic interventions and the early clinical course were examined.

RESULTS

The mean Injury Severity Score (ISS) was 36.9: 70 (67.3%) patients were male and 34 (32.7%) female; the median age was 36.1 years. Traffic accidents were the most frequent trauma mechanism (78.9%) followed by falls from height (17.3%). The mean period between trauma and trauma emergency room was 0.73 h; 77 (74.0%) patients were intubated and mechanically ventilated at the scene and all patients received analgosedation. The mean preclinical fluid load was 1673 ml. The mean duration of treatment in the emergency room was 53 min. The mean length of intensive care was 8.6 days and the mortality rate was 19.2% within the first 24 h.

CONCLUSION

Major trauma is an important cause for requesting a primary HEMS mission. As the results of this study show, immediate and invasive interventions at the scene lead to an improvement of vital functions at admission. For the patients' further course of treatment, the choice of a trauma center seems to be important, too.

A new generation of artificial ligaments in reconstruction of the anterior cruciate ligament. Two-year follow-up of a randomised trial

We have undertaken a randomised clinical trial comparing two methods of reconstruction of the anterior cruciate ligament in patients with chronic instability. We used an ipsilateral bone-patellar-tendon-bone autograft in 27 patients and the Ligament Advancement Reinforcement System (LARS) artificial ligament in 26. Assessment before and at two, six, 12 and 24 months after surgery, included the history, physical examination, a modified International Knee Documentation Committee (IKDC) score, the Tegner score, the Knee Injury and Osteoarthritis Outcome Score (KOOS) and instrumented laxity testing. There were no cases of reactive synovitis or of infection of the knee, and there was no difference regarding the failure rate between the two groups. The IKDC showed no significant differences between the two groups at any stage of the follow-up. The KOOS evaluation showed consistently better results in all subscales for the LARS group during the first year of follow-up. After 24 months these differences were no longer evident. Instrument-tested laxity was greater in the LARS group at all stages of follow-up, but the differences were not significant at 24 months. Our findings suggest that at follow-up at 24 months the LARS ligament seems to be a satisfactory treatment option, especially when an early return to high levels of activity is demanded.

The diagnostic dilemma of traumatic rupture of the diaphragm

BACKGROUND

Traumatic rupture of diaphragm is caused by blunt or penetrating trauma. Early diagnosis is difficult, and complications such as visceral herniation may arise. A 10-year evaluation of all diagnostic procedures used in patients with surgically proved traumatic rupture of the diaphragm is presented.

METHODS

A review of all patients with surgically proved diaphragmatic injury from 1988 to 1998 was conducted. All diagnostic methods were analyzed in terms of their ability to identify diaphragmatic rupture.

RESULTS

During the study period, 31 patients with a mean age of 34 years were treated. Of these patients, 20 sustained blunt trauma and 11 experienced penetrating trauma. The initial chest x-ray was diagnostic for 6 of the 31 patients, nonspecific for 15 of the patients, and normal for 10 of the patients. In no case was sonography diagnostic. Thoracoabdominal computed tomography (CT), performed in 22 of the patients, led to diagnosis for 5 patients and unspecific findings for 17 patients. Statistical analyses showed no significant difference between initial chest x-ray and thoracoabdominal CT. No significant difference between blunt or penetrating trauma or between left-side and right-side ruptures could be recognized with any diagnostic tool.

CONCLUSIONS

All the diagnostic methods investigated in this study showed unsatisfying results, and traumatic rupture of the diaphragm seems to remain a diagnostic dilemma. Endoscopic techniques not tested in this study and discussed controversially may offer a good chance for early diagnosis and repair of the injured diaphragm.

Giant-cell tumor of the synovial membrane: localized nodular synovitis in the knee joint

Giant-cell tumor of the synovia is a benign neoplasm characterized histologically by proliferating histiocytes bearing lipids and hemosiderin intermingled with a variable number of multinuclear giant cells. Areas of predilection are the hand, and in the case of synovial joints, the knee joint is particularly affected. Clinically, patients have signs of mechanical derangement and, with the knee joint, meniscal symptoms and locking are often present. Joint effusion without previous trauma is another typical finding. Diagnosis is carried out by radiographic tools and has to be confirmed histologically. Giant-cell tumor of the synovia is treated by local excision either by arthroscopy or by arthrotomy. To our knowledge, the case we present is the largest giant-cell tumor of the synovia in the knee joint ever described in literature.

[Ethylene glycol poisoning and brain injury--a dangerous combination]

We report on a patient after brain injury additionally showing signs of ethylene glycol intoxication. CT-scan showed a subdural hematoma, which in spite of increasing neurological deficit didn't show any enlargement. Metabolic acidosis with an increased anion gap and osmolar gap led to the diagnosis of ethylene glycol intoxication. Then intensive hemodialysis and i.v. ethanol were administered and the intoxication could be treated successfully.

[New therapeutic possibilities for ankle injuries]

The demand for minimally invasive techniques and more comfort for the patient is becoming higher and higher. In the region of the ankle joint, it is therefore ideal to use the arthroscope for pathology. Indications for ankle joint arthroscopy are: soft tissue impingement, ligament instability, impingement in the syndesmosis, osteochondral lesions, loose bodies, arthrosis, and loose os trigonum of the talus. In the subtalar joint the indications are rupture of the ligaments, loose bodies, and synovitis with soft tissue impingement. A new indication is arthroscopically assisted arthlodesis of the talar and subtalar joint. The reported high incidence of complications, especially in terms of neurovascular lesions, can be avoided by an exact knowledge of anatomy and use of non-invasive distraction of the joint.

[Fatal pulmonary embolism after lysis therapy in post-traumatic renal vein thrombosis]

A 30-year-old man was hospitalized because of increasing dyspnoea for 4 weeks. Chest X-ray demonstrated an infiltrate in the right upper lobe and enlargement of the central pulmonary arteries. Lung perfusion scintigraphy revealed, typical of embolism, absent perfusion of the entire right upper lobe, as well as segmental embolism in the left upper and basal lobes. Phlebography of the legs and pelvis was unremarkable. Intravenous heparin treatment was begun (initially 1,250 IU/h, then dosage adjusted according to the partial thromboplastin time). Nonetheless the patient's condition deteriorated the next day and the respiratory failure increased (pO2 61 mm Hg despite oxygen supply). Streptokinase was then infused in ultra-high dosage, 9 million units over 6 hours. But the patient died of cardiocirculatory failure 4 hours after the streptokinase infusion had been finished. Autopsy revealed fulminant recurrent pulmonary embolism with occlusion of the right main pulmonary artery. The emboli had their origin in renal vein thrombosis extending into the inferior vena cava, which had probably been caused by slight trauma to the flank during a game of squash 6 weeks previously.
