RESUMEN
In the context of their offer of interdisciplinary multimodal pain therapy (day-patient and inpatient), hospitals repeatedly have to contend with strict detailed checks of the procedure codes (OPS 8-918.xx; 8-91c) by health insurers and the medical service. The necessity of day-patient or inpatient treatment in the respective sector, documented therapy components, and the qualifications of the therapists are regularly reviewed. On 27 October 2020, the Federal Social Court ruled on the specific qualification of psychological psychotherapists (BSG, 27 October 2020, Ref.: B 1 KR 25/19 R). The ruling and its potential impact are explained and discussed in this overview.

During the 2020 coronavirus pandemic, a lockdown was imposed in France during the first wave. An apparent decrease in incidence of cellulitis of odontogenic origin was noticed then. This study aimed to compare the incidence of cellulitis during this extraordinary period with the same period in 2018 and 2019, based on retrospective multicentric data. All maxillofacial surgery departments in French public hospitals were contacted. Responders were asked to include all patients admitted for the surgical drainage of a head and neck abscess of odontogenic origin during the first 2020 lockdown period, and in a similar time frame in 2018 and 2019 (control group), based on screening the French diagnostic and therapeutic classification of medical acts. We report a 44% significant nationwide decrease in the incidence of admissions for cellulitis. There were 187 patients in 2020 for 334 and 333 patients in 2018/2019 respectively. The reasons to explain this finding are hypothetical (organizational reasons leading to earlier management, patients' fear to seek for medical management, usual excess in surgical indications or concomitant decrease of non-steroidal anti-inflammatory drugs delivery). Whatever the explanation, it would be of great interest to find it out in order to improve the prevention of cellulitis.

The coronavirus disease 2019 (COVID-19) outbreak has had a major impact on medical and surgical activities. A decline in facial trauma incidence was noticed during the lockdown period. The aim of this study was to evaluate the decline in maxillofacial trauma in France during this particular period. A retrospective multicentre comparative study was initiated in 13 major French public hospital centres. The incidence of facial trauma requiring surgery during the first month of lockdown was compared to that during equivalent periods in 2018 and 2019. Differences in the types of trauma were also analysed. Thirteen maxillofacial departments participated in the study. A significant decline in maxillofacial trauma volumes was observed when compared to equivalent periods in 2018 and 2019 (106 patients compared to 318 and 296 patients, respectively), with an average reduction of 65.5% (P=0.00087). The proportion of trauma due to sports and leisure was reduced when compared to reports in the literature. As a consequence, in the context of a pandemic, the material and human resources related to this activity could be reallocated to the management of other pathologies that cannot be postponed.

Defects affecting the anterior wall of the tympanal bone can result from trauma, infection, neoplasm or previous local surgery. An anatomic variation, namely the persistence of the foramen tympanicum, can also be encountered. When symptomatic, surgical reconstruction may be indicated. The aim of this study was to identify the surgical treatments of symptomatic foramen tympanicum found in the literature and detail our innovative reconstruction technique. A bibliographic research was conducted in PubMed database in March 2020, without time limitation. Papers dealing with surgical management of a foramen tympanicum were included. Data collected were the publication date, the number of patients, their age and gender, the symptoms and the surgical treatment performed. We report, in addition, the case of a symptomatic persistent foramen tympanicum in a 30-year-old man with a follow-up of 18-months. A total of 17 studies (n=23 patients) were included for analysis. The main reconstruction techniques were, in equal proportion, cartilage graft (30%) and insertion of a titanium mesh (30%). We carried out an iliac crest bone graft using a preauricular approach on a patient suffering from chronic tinnitus and fullness in the left ear resulting from a persistent foramen tympanicum, confirmed by clinical and radiological examinations. It allowed the complete resolution of symptoms and no complication such as temporomandibular ankylosis occurred. Based on the review of the literature, we believe this technique has the advantage of providing durable reconstruction thanks to osseointegration.

Interdisciplinary multimodal pain therapy (IMST) is recognized as a scientifically founded form of therapy for inpatient treatment of chronic pain conditions. The indications are assessed by private practitioners and must be confirmed by physicians at the inpatient institution. The health insurance companies are obliged to remunerate this treatment but are allowed to test the conditions in individual cases. Recently, reports from members of the German Pain Society on a drastic increase in testing and rejection quotas have become more frequent. Therefore, this article discusses the legal foundations of the treatment of patients with chronic pain in the inpatient sector. Hard criteria for treatment in a certain sector could not be established. A decision in individual cases will depend on the complexity of the disease in the individual patient. A treatment in hospital is principally only necessary when the treatment corresponds to the generally recognized state of medical knowledge and treatment options in daycase units have not been successful. Important guidance can be found in the treatment guidelines of the medical specialist societies. The transfer to a more intensive treatment sector must be made dependent on the severity and complexity of the symptoms and the insufficient effectiveness of the treatment in the previous sector. Simple ICD-10 diagnoses are not suitable as decision-making criteria and therefore, also not as testing criteria for the indications for inpatient treatment. Decompensated and acutely exacerbated chronic pain conditions must as a rule be treated in hospital, also due to the mental component of the pain disease.

The advent of customized three-dimensional (3D) printing allows the affordable manufacturing of sophisticated medical devices, thereby providing swift and simple solutions to specific needs in modern healthcare. Meanwhile, certain devices such as industrial mandibular external fixators (EFs) have become less and less available from medical device companies because of decreased indications. What is more, their handling is often complex. The authors report, step by step, the original design and uneventful clinical use of a 3D-printed, customized mandibular EF. This device was designed together with a positioning and drilling guide for the fixation of a septic mandibular pseudarthrosis. It provided an adequate and satisfactory balance between lightness and rigidity. A simple, accurate and safe placement of the EF was achieved thanks to the skin-supported positioner and drilling guide, thereby making the procedure minimally invasive and time-efficient. To our knowledge, this is the first reported clinical use of a 3D-printed, customized mandibular EF to date. Because such 3D technology is becoming increasingly available to a large number of surgeons, the authors believe that the present innovation could become an alternative to reusable standard EFs.

Mandibular reconstruction using computer-aided design/computer-aided manufacturing cutting guides is currently a common procedure. However, inaccurate positioning of the cutting guide onto the fibular bone may result in osteosynthesis difficulties or imprecision in the reconstruction. A novel way to improve the stability of the cutting guides may be to add pillars in order for them to be suspended from the fibula, avoiding soft tissues interactions. We present the case of a 39-year-old male who needed mandibular reconstruction after a self-inflicted ballistic injury. We designed a customized cutting guide which included a set of 8 pillars allowing a suspension of the cutting guide 8 millimeters above the bone level. The pillars were perpendicular to one another, and allowed the operator to screw the cutting guide to the bone. The orthogonal position of the pillars enabled real stability during the osteotomies. In the operator experience, the length of the pillars was too important, and led to incomplete osteotomies, and the whole device was too bulky. However, with adaptations in the size of the pillars and the size of the whole device, this solution could be useful in cutting guide design to avoid impairments due to the soft tissues surrounding the fibula.

Polymers that depolymerize back to monomers can be repeatedly chemically recycled, thereby reducing their environmental impact. Polyphthalaldehyde is a metastable polymer that can rapidly and quantitatively depolymerize due to its low ceiling temperature. However, the effect of substitution on the physical and chemical properties of polyphthalaldehyde derivatives has not been systematically studied. Herein, we investigate the cationic polymerization of seven o-phthalaldehyde derivatives and demonstrate that judicious choice of substituent results in materials with a wide range of ceiling temperatures (<-60 to 106 °C) and decomposition temperatures (109-196 °C). We anticipate that these new polymers and their derivatives will enable researchers to access degradable materials with tunable thermal, physical, and chemical properties.
RESUMEN
This study was performed to present the authors' experience with botulinum toxin therapy for salivary stenosis and salivary fistula in terms of the procedure, dosage, effectiveness, and complications. A retrospective study of all patients treated in the maxillofacial surgery department for salivary stenosis or fistula from January 2014 to September 2018 was performed. Intraglandular injections of incobotulinumtoxinA (Xeomin) were utilized. The frequency of relapse and the pain recorded before injection and at 3 months after each injection or fistula resolution were assessed. Swallowing dysfunction or any diffusion of toxin into the facial muscles was recorded. This study included 22 patients (mean age 53 years). Botulinum therapy was indicated for parotid duct stenosis in 14 patients, submandibular duct stenosis in four patients, and parotid fistula in four patients. The frequency of relapse (P = 0.0001) and pain level (P = 0.0001) decreased after botulinum therapy. The average duration of the botulinum effect was 4.50±2.00 months after the first injection. No complication was observed. Botulinum therapy with 100 IU of Xeomin proved effective at resolving salivary fistula. Botulinum therapy is an effective treatment for symptoms of salivary duct stenosis in patients for whom minimally invasive procedures have failed. Botulinum therapy can also be used for the treatment of salivary fistulas.

Advances in medical care have led to an increasing number of immunocompromised travellers. Travellers with immunodeficiencies have a higher risk of infections and can acquire infectious diseases that are rare in immunocompetent travellers. Of central interest are travellers' diarrhea, diseases of the respiratory tract, tuberculosis and inhalative mycoses as well as diseases transmitted by vectors such as malaria. For every such journey a timely consultation in travel medicine is indicated. First the individual risk must be assessed according to the degree of immunodeficiency. An individual counselling is then related to the itinerary, the travel destination and any activities planned. This information is the basis for an individual set of prophylactic measures with respect to infections and other risks through certain modes of behavior, medication, and vaccinations. Post-travel counselling and evaluation are equally important. This requires physicians experienced in both immunosuppression and travel medicine.

Based on the fundamental concept of the biopsychosocial model, interdisciplinary multimodal pain therapy (IMPT) has developed to one of the most important components in the treatment of patients suffering from chronic pain. The process criteria for IMPT in Germany are described in the German OPS catalogue and IMPT is mainly offered as an inpatient treatment only. This article updates some of the fundamental criteria for IMPT for adult inpatient treatment and the task force defines basic structural and process criteria for the implementation of IMPT for outpatients.

INTRODUCTION: Three-dimensional imaging of facial surfaces is a useful tool in different fields of cranio-facial, maxillo-facial and facial aesthetic surgery. Many devices that use several stereoscopic cameras are available but require a dedicated room. In contrast, the Vectra H-1 is a handheld device that can be used regardless of location but requires three consecutive acquisition and might therefore provide less accuracy. The aim of this study was to assess the accuracy, repeatability and reproducibility of the Vectra H1 device to validate its use in daily medical practice. MATERIAL AND METHODS: A comparative analysis of the Vectra H1 device and a digital calliper was performed based on 23 distances measured among 11 facial landmarks. One operator repeated the procedure six times on a 24-year-old male volunteer to assess repeatability, and six operators performed the measurement procedure on a 22-year-old female volunteer to assess reproducibility. Repeatability, reproducibility and accuracy versus the distances measured were successively assessed by testing the correlations between the distances measured versus the coefficient of variation (CV) calculated for repeatability, reproducibility and accuracy. RESULTS: The CVs for all distances ranged from 0.34% to 1.53% and decreased linearly when distances measured increased, and this correlation was significant (P = 0.0026) for repeatability. The CVs for all distances ranged from 0.23% to 2.90% and decreased linearly as distances measured increased; there was a significant correlation (P = 0.00045) for reproducibility. CONCLUSIONS: This study shows that the Vectra H1 provides an accurate linear assessment of clinical parameters and allows the accurate analysis of craniofacial morphology. Furthermore, this device costs less and requires less space than other multi-pod devices.

Being in control of one's emotions is not only desirable in many everyday situations but is also a great challenge in a variety of mental disorders. Successful intentional emotion regulation is related to down-regulation of amygdala activity. Training mental interventions supported by neurofeedback of one's own amygdala activity using real-time (rt-)fMRI might be beneficial for mental health and well-being. Rt-fMRI guided amygdala-downregulation using cognitive interventions such as a "reality check", however, have not been well-investigated. Fifteen healthy subjects underwent four rt-fMRI sessions with neurofeedback of their own amygdala activity while applying a reality check as an emotion regulation strategy in order to down-regulate their amygdala signal during a stimulation with emotional pictures. The Control group comprised of eleven subjects also trained emotion regulation but without obtaining feedback. We hypothesized more prominent down-regulation of amygdala activity at the end of the training in the Feedback group. We investigated effects over time and between groups and further task specific connectivity of the amygdala by using psychophysiological interaction analyses. Four weekly amygdala-based feedback sessions resulted in significantly decreased amygdala activity (pâ¯=â¯0.003, dâ¯=â¯0.93), also compared to the Control group (pâ¯=â¯0.014, dâ¯=â¯1.12). Task specific connectivity of the amygdala with the anterior cingulate cortex, hippocampus and distinct prefrontal areas was increased in the Feedback group. Training of emotion regulation supported by rt-fMRI neurofeedback resulted in a prominent amygdala down-regulation compared to training without feedback. The finding implicates successful emotion regulation, compliant with emotion control models, through an easily applicable reality check strategy. Rt-fMRI neurofeedback may support emotion regulation learning and bears clinical potential for psychotherapy.

The rate of segmental resection for early stage non-small cell lung carcinoma (NSCLC) is increasing. However, the indications remain controversial. The aim of this study is to analyze the preliminary results of thoracoscopic segmental resection in early stage NSCLC in terms of morbidity, oncological validity and survival. We report the preliminary results of a consecutive series of 226 thoracoscopic segmentectomies for suspicion of early stage NSCLC. PATIENTS AND METHODS: Between 2007 and 2016, we performed 322 thoracoscopic anatomical sublobar resections (ASLR). Two hundred and twenty six of these were for suspicion of early stage NSCLC in 222 patients. Data were recorded prospectively and analysed retrospectively on an intent-to-treat basis. Overall and disease-free survivals were estimated on a Kaplan-Meier curve and differences were calculated by a log-rank test. RESULTS: Twenty-two patients were upstaged (10.4%), in 10 cases to T3 or T4, in 6 cases to N1 and in 6 others to N2 for metastasis. Out of the 6 N1 cases, 3 were discovered at frozen section and resulted in a switch from segmentectomy to lobectomy. There were 10 conversions to thoracotomy (3.9%). Seventeen patients had a more extensive resection than initially planned (7.5%), most often for oncological reasons: invasion of intersegmental lymph nodes (n=3) or insufficient resection margin at frozen section (n=7). Morbidity and mortality were 25.7% and 1.3 % respectively. For pT1aN0 carcinomas, overall and disease-free survivals were 87.1% and 80.6%, respectively. For pT1bN0 carcinomas, overall and disease-free survivals were 88.8 %, and 75.3% respectively. CONCLUSION: For early stage NSCLC, thoracoscopic ASLR allows reduced perioperative morbidity while offering satisfactory survival. However, a rigorous technique must be applied to reduce the rates of conversion to thoracotomy and extension to lobectomy when required for oncological reasons.

This report describes a three-component, Ni-catalyzed reductive coupling that enables the convergent synthesis of tertiary benzhydryl amines, which are challenging to access by traditional reductive amination methodologies. The reaction makes use of iminium ions generated in situ from the condensation of secondary N-trimethylsilyl amines with benzaldehydes, and these species undergo reaction with several distinct classes of organic electrophiles. The synthetic value of this process is demonstrated by a single-step synthesis of antimigraine drug flunarizine (Sibelium) and high yielding derivatization of paroxetine (Paxil) and metoprolol (Lopressor). Mechanistic investigations support a sequential oxidative addition mechanism rather than a pathway proceeding via α-amino radical formation. Accordingly, application of catalytic conditions to an intramolecular reductive coupling is demonstrated for the synthesis of endo- and exocyclic benzhydryl amines.

With the implementation of the German diagnosis-related groups (DRG) reimbursement system in hospitals, interdisciplinary multimodal pain therapy was incorporated into the associated catalogue of procedures (OPS 8918). Yet, the presented criteria describing the procedure of interdisciplinary multimodal pain therapy are neither precise nor unambiguous. This has led to discrepancies in the interpretation regarding the handling of the procedure-making it difficult for medical services of health insurance companies to evaluate the accordance between the delivered therapy and the required criteria. Since the number of pain units has increased in recent years, the number of examinations by the medical service of health insurance companies has increased. This article, published by the ad hoc commission for interdisciplinary multimodal pain therapy of the German Pain Association, provides specific recommendations for correct implementation of interdisciplinary multimodal pain therapy in routine care. The aim is to achieve a maximum level of accordance between health care providers and the requirements of the medical examiners from health insurance companies. More extensive criteria regarding interdisciplinary multimodal pain treatment in an in-patient setting, especially for patients with chronic and complex pain, are obviously needed. Thus, the authors further discuss specific aspects towards further development of the OPS-code. However, the application of the OPS-code still leaves room regarding treatment intensity and process quality. Therefore, the delivery of pain management in sufficient quantity and quality still remains the responsibility of each health care provider.

Capnocytophaga canimorsus is a Gram-negative bacterium present in the oral cavities of cats and dogs. It is known for its capability to cause life-threatening sepsis following a dog bite, especially in immunocompromised patients. We report the case of a 67-year-old man who suffered from septic shock and multiorgan failure presumably following contamination of a pre-existing minor skin lesion by canine saliva. The purpose of this report is to raise awareness of Capnocytophaga canimorsus among physicians when faced with a patient presenting with fulminant septic shock and Gram-negative bacteremia, who has been exposed to dogs.
