RESUMEN
PURPOSE: Vaccination is the key element for protection against COVID-19. Increased vaccination breakthroughs raise the question of whether additional prevention is necessary in case of individual risk factors for a severe course with hospitalization or death despite vaccination. METHODS: Since July 13, 2021, there is an extended reporting requirement by German law. We analyzed our hospitalized patients with vaccine breakthrough infection during the first 8 weeks. RESULTS: Nine of 67 patients (13.4%) hospitalized for COVID-19 (median age 75 years) were fully vaccinated. Five of these patients received intensive care; two patients died. All had received two doses of BNT162b2 vaccines (Pfizer-BioNTech). There was a median of 99 days between complete immunization and symptom onset. All patients suffered from ≥ three comorbidities. Six patients (66.7%) showed a negative Anti-SARS-CoV-2-N titer at the time of vaccine breakthrough, five of these also had Anti-SARS-CoV-2-S titers < 100 U/ml. All determinable cases were Delta variant B.1.617.2. CONCLUSION: Advanced age, underlying cardiorespiratory disease, and the Delta variant of SARS-CoV-2 were associated with hospitalization of our patients, suffering from vaccine breakthrough infection. Avoidance of face masks, lack of immunization of close contacts, and travel to high-risk areas have been observed as modifiable behavioural circumstances. Consistent personal protective measures, vaccination of close caregivers, and increased awareness might be effective measures in addition to COVID-19 booster vaccination for patients at a high risk to suffer a severe course of infection.

BACKGROUND: Due to the limited compliance, the technically correct collection of a pooled nasopharyngeal swab is significantly more difficult in children. Especially during operations in the area of the upper respiratory tract, there is a significantly increased risk of infection with COVID-19 for everyone present in the operating room. The aim of the study is to analyze the validity of SARS-CoV-2 swabs taken preoperatively under suboptimal conditions. MATERIAL AND METHODS: Retrospective comparison of the PCR results of SARS-CoV-2 swaps taken preoperatively and intraoperatively from 62 children in the period from April to July 2020. Median age was 4.49 years. The PCR diagnosis was carried out one or two days preoperatively (in the case of emergency interventions on the same day) and again intraoperatively using a pooled nasopharyngeal swab. RESULTS: All 62 preoperatively taken swabs were negative. Deviating from the preoperative test result, one intraoperatively obtained swab was positive. CONCLUSIONS: Due to limited compliance, a correct preoperative swab technique (preanalytics) cannot always be assumed for children. Sufficient protective measures for everyone present in the operating room are therefore imperative. Intraoperative test should be considered if the preoperative test was performed under difficult conditions.

Prenatal, perinatal, and postnatal factors have been shown to shape neurobiological functioning and alter the risk for mental disorders later in life. The gut microbiome is established early in life, and interacts with the brain via the brain-immune-gut axis. However, little is known about how the microbiome relates to early-life cognitive functioning in children. The present study, where the fecal microbiome of 380 children was characterized using 16S rDNA and metagenomic sequencing aimed to investigate the association between the microbiota and cognitive functioning of children at the age of 45 months measured with the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III). Overall the microbiome profile showed a significant association with cognitive functioning. A strong correlation was found between cognitive functioning and the relative abundance of an unidentified genus of the family Enterobacteriaceae. Follow-up mediation analyses revealed significant mediation effects of the level of this genus on the association of maternal smoking during pregnancy and current cigarette smoking with cognitive function. Metagenomic sequencing of a subset of these samples indicated that the identified genus was most closely related to Enterobacter asburiae. Analysis of metabolic potential showed a nominally significant association of cognitive functioning with the microbial norspermidine biosynthesis pathway. Our results indicate that alteration of the gut microflora is associated with cognitive functioning in childhood. Furthermore, they suggest that the altered microflora might interact with other environmental factors such as maternal cigarette smoking. Interventions directed at altering the microbiome should be explored in terms of improving cognitive functioning in young children.

BACKGROUND: At the beginning of the COVID-19 pandemic, the German Robert Koch Institute (RKI) published several guidelines addressing the medical health services helping to detect SARS CoV2. Needing an available and specific test strategy regarding SARS-CoV2, our own test strategy strictly followed these testing criteria. MATERIALS AND METHODS: Using a retrospective analysis, we verified if such a test strategy was an effective tool in the context of infection prevention control and as reliable SARS-CoV2 detection. Therefore, we analysed our own test results of suspected SARS-CoV2 cases between 26 February and 6 April 2020. Additionally, we used a geovisualisation tool to visualise test frequencies and positive test results within different districts of Mannheim based on people's addresses. RESULTS: There were on average 7% positive test results of SARS-CoV2 within a population with typical symptoms of COVID-19 (nâ¯= 2808). There was no positive test result within an asymptomatic population (nâ¯= 448). However, one positive test result turned out to be a nosocomial infection. Finally, geovisualisation highlighted a shift of test frequencies and local positive rates for SARS-CoV2 from one district of Mannheim to another. DISCUSSION: In conclusion, our test strategy strictly based on testing criteria suggested by the Robert Koch Institute resulted in a steady rate of positive tests and allowed us to increase test capacity without causing numbers of nosocomial infections of COVID-19. Geovisualisation tools can offer support in analysing an ongoing spread of transmissible diseases. In the future, they could be used as helpful tools for infection prevention control, for example in the context of vaccination programs.

BACKGROUND: There is a lack of experience with fully covered self-expandable metal stents (SEMSs) for the treatment of esophageal leakage particularly in infants and neonates. METHODS: Eight patients (5M, 3F) with a median age of 17 months (range, 1-135 months) who underwent treatment with SEMSs for an anastomotic leakage or perforation of the esophagus were recruited to this retrospective study. Four children were born premature. In six patients the stents were placed primarily as an emergency procedure. RESULTS: Median duration of individual stent placement was 42 days (range, 13-72 days). Six out of eight patients (75%) were treated with one stent only. In three preterm infants who had their stents inserted within the first month relative weight gain was 17% compared with 2% in five patients who were treated later in life (p=0.0986). In four cases (50%) distal migration of the stent was observed. Seven out of eight patients (88%) had their leakage resolved after stent therapy. CONCLUSIONS: Insertion of fully covered SEMSs is an alternative tool for the treatment of esophageal leakage in children and preterm infants, and successful with only one single application in selected cases. It can be used either following previous therapy or as part of an emergency procedure. Because of the absence of manufactured, age-related devices SEMSs that are originally designed for other organs can be applied.

BACKGROUND: Despite recent studies failing to prove beneficial effects of iNO therapy in patients with CDH, its use is still widespread. The aim of this work was to analyze iNO use in a retrospective cohort focusing on outcome parameters. Patients 378 CDH patients born and treated in Mannheim University Medical Center, Department for Neonatology, between 2010 and 2017 constituted our cohort. Therapy was based on the standardized protocol of the CDH EURO Consortium. METHOD: General data (sex, birth weight, gestational age etc.) and therapy-related data (duration of iNO application, OI after 60 mins, need for ECMO support etc.) were collected from clinical reports and then conducted using SAS for both mono- and multivariate analyses. RESULTS: Out of 378 newborns with CDH, 265 received iNO (70.1%), of whom 82 (30.9%) showed a significant OI reduction of ≥5 pts after 60 mins (=responders), median OI improved by 1.85 pts overall. Among initial responders iNO, application reduced the need for ECMO support (p=0.0054), increased the time to ECMO initiation (p=0.005) and reduced mortality (p=0.0396). DISCUSSION: A group of 43 patients considerably benefited from iNO and thererfore as they did not need ECMO support. Even though iNO therapy has failed to prove significant beneficial effects for non-responders, the application is still to be considered an essential treatment method in the transitional period of CDH patients. CONCLUSIONS: A more critical approach towards iNO application in nonresponders should be promoted. Further extensive multicenter studies on treatment alternatives for CDH-PAH are desirable.

Aim: Management of a SARS-CoV-2 outbreak in geriatric patients, taking into account the transition to the post-pandemic period. Methods: PCR tests were conducted to identify the scale of infection during the outbreak; no new patients were admitted to the ward until the availability of the PCR results. Based on the results and individual risk assessment, three cohorts were formed and treated as recommended by the RKI. After terminating the admissions stop, new admissions received PCR screening. Contact patients were retested on days 3 and 5. Employees carried out self-monitoring, and if symptoms developed, an antigen test was performed. Results: Nine of the 11 PCR-positive patients (6m, 5f), median age 85 years, were immunized. Eight patients were symptomatic, ten received antiviral therapy and two required intensive care. Three symptomatic employees had a positive antigen test. Patients without direct contact to the positive cases who initially tested negative and the 16 new admissions with a negative PCR test did not contract COVID-19. Outbreak management ended after 15 days without deaths from COVID-19. Conclusion: During the outbreak, PCR screening, the temporary stop in new admission until the availability of PCR results, and the risk-adapted cohorting of patients supplemented by consistent PCR tests of new admissions formed the basis for successful outbreak management. Treatment can be made possible despite high vulnerability. Close symptom monitoring and rapid implementation of measures reduce the risk. Repeated PCRs of direct-contact patients on day 3 can warrant pre-emptive antiviral therapy despite being asymptomatic; testing on day 5 makes it possible to shorten preventive isolation measures. The use of protective masks and self-monitoring by employees are fundamental to preventing further infections.
RESUMEN
BACKGROUND: The aim of the rapid introduction of vaccines during the COVID-19 pandemic was a reduction in SARS-CoV-2 transmission and a less frequent occurrence of severe COVID-19 courses. Thus, we evaluated COVID-19 severity in vaccinated individuals to examine variant-specific symptom characteristics and their clinical impact on the serological immune response. METHODS: A total of 185 individuals previously vaccinated against and infected with the SARS-CoV-2 Delta (B.1.617.2) or Omicron (BA.4 and BA.5) variant, were enrolled for anti-SARS-CoV-2 anti-N- and anti-RBD/S1-Ig level detection. A structured survey regarding medical history was conducted. RESULTS: In 99.5 percent of cases, outpatient treatment was satisfactory. Specific symptoms associated with variants included ageusia and anosmia in patients with Delta infections and throat pain in Omicron infections. Among Delta-infected individuals with specific symptoms, significantly higher levels of anti-N antibodies were observed. CONCLUSION: Our study identified variant-specific differences in the amount of SARS-CoV-2 antibody production and COVID-19 symptoms. Despite this, vaccinated individuals with Omicron or Delta infections generally experienced mild disease courses. Additionally, asymptomatic individuals exhibit lower anti-SARS-CoV-2 antibody levels, indicating a clinical correlation between disease-specific antibodies and distinct symptoms, particularly in the case of the Delta variant. In follow-up studies, exploring post-COVID syndrome and focusing on cognitive symptoms in the acute phase of Omicron infections is crucial as it has the potential to longitudinally impact the lives of those affected.
RESUMEN
BACKGROUND: Management of pediatric thermal injuries involves a high standard of care in a multidisciplinary setting. To avoid physical and psychological sequelae, wound dressings should minimize hospitalization time and anesthesia while maximizing patient comfort. PATIENTS AND METHODS: 190 children with thermal injuries of the torso, arms and legs were treated with polyurethane foam dressings or bacterial nanocellulose sheets. Data were analyzed retrospectively regarding hospitalization, procedures with general anesthesia, scar formation, rate of infection and need for skin grafting. RESULTS: The groups did not differ significantly concerning age, gender distribution or percentage of injured total body surface area. Statistical analysis showed that length of hospitalized care and procedures undergoing anesthesia were significantly reduced in the nanocellulose group (each p < 0.0001). There was no significant difference in rate of complications, wound healing and rate of skin grafting between the two subgroups. DISCUSSION: Acting as a temporary epidermal substitute, bacterial nanocellulose enables undisturbed reepithelialization without further wound dressing changes. In children, no additional topical antimicrobial agents are indicated for unimpaired wound healing. CONCLUSIONS: Bacterial nanocellulose is superior to polyurethane foam regarding length of hospitalization and number of interventions under anesthesia. It offers a safe, cost-effective treatment option and provides excellent comfort in pediatric patients.

The causative agent of legionellosis is the Gram-negative intracellular bacteria Legionella spp. Its clinical presentation varies from a mild febrile illness called Pontiac fever to the severe and possible fatal pneumonia, Legionnaires' disease. Immunocompromised patients, in particular, are affected. Only a small number of infected neonates are described in the literature. Most of them have been associated with water birth or the use of air humidifiers. In the last five years, a growing number of cases have been reported in Germany by the national institute of disease surveillance and prevention (Robert-Koch Institute). Here, we describe a fatal case report of pulmonary legionellosis with acute respiratory distress syndrome (ARDS), sepsis, associated cutaneous manifestation, and extracorporeal membrane oxygenation in a full-term neonate. Moreover, we present a review of the literature discussing the epidemiology, risk factors, clinical features, diagnostics, treatment options, and prevention for this rare condition in neonates.
RESUMEN
Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is a neuroinflammatory condition mediated by autoantibodies against the GluN1 subunit of the receptor. Clinically, it is characterized by a complex neuropsychiatric presentation with rapidly progressive psychiatric symptoms, cognitive deficits, seizures, and abnormal movements. Isolated psychiatric manifestations of anti-NMDAR encephalitis are rare and usually dominated by psychotic symptoms. We present a case of an 18-year-old female high school student-without a previous history of psychiatric disorders-with a rapid onset severe depressive syndrome. Surprisingly, we found pleocytosis and anti-NMDAR autoantibodies in the cerebrospinal fluid (CSF), despite an otherwise unremarkable diagnostic workup, including blood test, clinical examination, and cranial magnetic resonance imaging (MRI). After intravenous immunoglobulins treatment, a complete remission of the initial symptoms was observed. In a follow-up 5 years later, the young woman did not experience any relapse or sequelae. Anti-NMDAR encephalitis can present in rare cases as an organic disorder with major depressive symptoms without distinct concomitant psychotic or neurological symptoms. A clinical presentation such as a rapid onset of symptoms, distinct disturbance in the thought process, restlessness, and cognitive deficits should prompt screening for NMDAR- and other neural autoantibodies to rule out this rare but debilitating pathology.
RESUMEN
A survey of hospitals on three continents was performed to assess their infection control preparedness and measures, and their infection rate in hospital health care workers during the COVID-19 pandemic. All surveyed hospitals used similar PPE but differences in preparedness, PPE shortages, and infection rates were reported.

The two main phytocannabinoids-delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD)-have been extensively studied, and it has been shown that THC can induce transient psychosis. At the same time, CBD appears to have no psychotomimetic potential. On the contrary, emerging evidence for CBD's antipsychotic properties suggests that it may attenuate effects induced by THC. Thus, we investigated and compared the effects of THC and CBD administration on emotion, cognition, and attention as well as the impact of CBD pre-treatment on THC effects in healthy volunteers. We performed a placebo-controlled, double-blind, experimental trial (GEI-TCP II; ClinicalTrials.gov identifier: NCT02487381) with 60 healthy volunteers randomly allocated to four parallel intervention groups, receiving either placebo, 800 mg CBD, 20 mg THC, or both cannabinoids. Subjects underwent neuropsychological tests assessing working memory (Letter Number Sequencing test), cognitive processing speed (Digit Symbol Coding task), attention (d2 Test of Attention), and emotional state (adjective mood rating scale [EWL]). Administration of CBD alone did not influence the emotional state, cognitive performance, and attention. At the same time, THC affected two of six emotional categories-more precisely, the performance-related activity and extraversion-, reduced the cognitive processing speed and impaired the performance on the d2 Test of Attention. Interestingly, pre-treatment with CBD did not attenuate the effects induced by THC. These findings show that the acute intake of CBD itself has no effect per se in healthy volunteers and that a single dose of CBD prior to THC administration was insufficient to mitigate the detrimental impact of THC in the given setting. This is in support of a complex interaction between CBD and THC whose effects are not counterbalanced by CBD under all circumstances.
RESUMEN
Purpose: There is a lack of experience with stenting for benign pancreaticobiliary disorders in children. Materials and Methods: Fifteen children (9 male and 6 female) with a median age of 7.1 years (range 0.7-14.2 years) who underwent treatment with a plastic stent for a benign disorder of the pancreaticobiliary system between May 2003 and September 2017 were recruited to this retrospective study. Results: Biliary and/or pancreatic plastic stents were inserted into 5 patients with congenital, 4 with post-traumatic, and 6 with idiopathic pathologies. Median duration of individual stent placement was 111 days (range 14-1569 days). Eleven children (73%) were treated with one stent only. In 4 cases, up to 22 stents were successively placed over time. There were no complications during stent insertion or stent removal. Seven patients (47%) experienced adverse effects during stenting, including choledocholithiasis, pancreaticolithiasis, cholangitis, acute pancreatitis, stent obstruction, and stent fracture. At follow-up, in 11 cases (73%), the underlying condition was resolved. In 4 children, all of whom suffered from congenital pancreaticobiliary disorders, stent therapy was considered as a temporary treatment before definite surgery. Conclusions: Patients with congenital anomalies of the pancreaticobiliary tree often require surgery for definitive management. However, temporary stent placement can be accomplished safely and successfully and this serves as a bridge to temporize their obstructive process while awaiting surgical intervention. Children with post-traumatic or idiopathic disorders can frequently be managed definitively by stenting alone and many of these require only one single stent insertion.

To review our institutional results and assess different surgical and non-surgical techniques for the treatment of displaced diametaphyseal forearm fractures in children and adolescents.Thirty-four children (25M, 9F) with a total of 36 diametaphyseal forearm fractures who underwent treatment under general anesthesia between July 2010 and February 2016 were recruited to this retrospective study. From October 2016 until March 2018 patients and/or parents were contacted by telephone and interviewed using a modified Pediatric Outcomes Data Collection Instrument (PODCI).Median age at the time of injury was 9.1 years (range, 1.9-14.6 years). Initial treatment included manipulation under anesthesia (MUA) and application of plaster of Paris (POP) (nâ=â9), elastic stable intramedullary nailing (ESIN) (nâ=â10), percutaneous insertion of at least one Kirschner wire (K-wire) (nâ=â16), and application of external fixation (nâ=â1). Eleven children (32%) experienced a total of 22 complications. Seven complications were considered as major, including delayed union (nâ=â1) and extensor pollicis longus (EPL) tendon injury (nâ=â1) following ESIN, as well as loss of reduction (nâ=â2) and refractures (nâ=â3) after MUA/POP. The median follow-up time was 28.8 months (range, 5.3-85.8 months). In 32 out of 34 cases (94%) patients and/or parents were contacted by telephone and a PODCI score was obtained. Patients who experienced complications in the course of treatment had a significantly lower score compared with those whose fracture healed without any sequelae (Pâ=â.001). There was a trend towards an unfavorable outcome following ESIN compared with K-wire fixation (Pâ=â.063), but not compared with POP (Pâ=â.553). No statistical significance was observed between children who were treated initially with a POP and those who had K-wire fixation (Pâ=â.216).There is no standard treatment for displaced pediatric diametaphyseal forearm fractures. Management with MUA/POP only is associated with an increased refracture rate. Based on our experience K-wire fixation including intramedullar positioning of at least one pin seems to be favorable compared with ESIN.

Nowadays, computed tomography (CT) is established for diagnosing gastrointestinal bleeding. In this retrospective study, the use of CT in diagnosing gastrointestinal bleeding was evaluated. Fifty-three patients received a contrast-medium-enhanced helical multislice CT (MSCT) to locate the bleeding site. Seventy-nine percent of the hemorrhage were acute gastrointestinal bleedings. Fifty-five percent of the acute hemorrhages were located via helical MSCT, 45% of the chronic bleeding sites were detected. Notably, bleeding of diverticula, tumors, and angiodysplasias were well demonstrated. In conclusion, contrast-medium-enhanced MSCT may be used effectively as a noninvasive diagnostic tool for detecting gastrointestinal bleedings.

STUDY DESIGN: This is a retrospective, self-controlled cohort study, at a single center. OBJECTIVE: The aim of this study was to evaluate the long-term outcome of sexual function after surgical treatment of single-level lumbar disk herniation (LDH). SUMMARY OF BACKGROUND DATA: The impact of surgical treatment on sexual activity is still unknown and not well researched. MATERIALS AND METHODS: In total, 114 patients who underwent disk surgery for LDH between 2009 and 2015 were included in the study (mean age, 46.9 y). Two separate questionnaires evaluating general health and all aspects of sexual function were administered to all patients. RESULTS: Satisfaction with the overall outcome of surgery was reported by 84.2% of patients. In total, 82 patients (71.9%) rated their current sexual life as normal with no additional pain, 22 (19.3%) reported a normal sex life with some additional pain, and 2 reported that (2.6%) pain prevents them from having any sex life at all. Compared with their state before LDH and spine surgery, 79 patients (69.3%) rated their sexual function as quantitatively and qualitatively the same as before surgery, 19 patients (16.7%) as better, and 16 patients (14.0%) as worse. The ability to experience orgasm, complete intercourse, experience sexual desire, and experience sexual arousal was reported to be the same as before surgery by 87 (76.3%), 75 (65.8%), 79 (69.3%), and 85 (74.6%) patients, respectively. After surgery, 16 patients (14%) explored new sexual positions. Sexual function receives insufficient attention from physicians. Women reported more general and sexual problems such as decreased sexual desire and interest, taking medication, and seeking regular medical attention. Predictors of the outcome were leg pain, the intensity of back and leg pain, and the professional status of the patient. CONCLUSIONS: Lumbar disk surgery has a positive effect on sexual function. The majority of patients returned to their normal sexual activities in long-term follow-up.

The term schizophrenia describes a group of multifaceted psychiatric conditions causing significant impairment of the quality of life of affected patients. Although multiple pharmacological treatment options exist, e.g. first- or second-generation antipsychotics, these therapeutics often cause disturbing side effects, such as extrapyramidal symptoms, prolactin increase, sexual dysfunction and/or metabolic syndrome. Furthermore, cognitive impairments and negative symptoms, two factors significantly influencing the course and outcome, are not sufficiently addressed by the available antipsychotics. Since its discovery, multiple clinical and preclinical studies have linked the endocannabinoid system to schizophrenia. Both the endocannabinoid anandamide and the cannabinoid CB1 receptor are deeply linked to underlying disease processes. Based hereon, clinical trials in schizophrenia have explored cannabidiol, a primary component of Cannabis sativa, and rimonabant, a partial antagonist to the CB1 receptor. While the latter did not reveal positive results, cannabidiol significantly ameliorated psychotic symptoms, which was associated with an increase in anandamide serum levels. However, the exact mechanisms of the antipsychotic effects of cannabidiol are not fully understood, and, furthermore, only a limited number of clinical trials in humans have been concluded to date. Thus, the level of proof of safety and efficacy required to approve the therapeutic use of cannabidiol in schizophrenia is currently lacking. However, cannabidiol is a promising candidate as an effective and mechanistically different antipsychotic treatment with a favourable side-effect profile. We therefore conclude that further studies are urgently needed to clarify the antipsychotic effects and safety profile of cannabidiol, and to fully explore its potential antipsychotic mechanism.

Nontraumatic adrenal hemorrhage in adults is uncommon and unexpected in the context of intracranial surgery. The authors report on a patient in whom hemodynamically relevant retroperitoneal bleeding developed within hours after an otherwise uneventful operation for a falcine meningioma. In this brief report they seek to draw attention to this rare but life-threatening complication, because rapid diagnosis can be life-saving.
