Clinical insights into traumatic injury of the inferior alveolar and lingual nerves: a comprehensive approach from diagnosis to therapeutic interventions

OBJECTIVES

This scoping review explores the risk and management of traumatic injuries to the inferior alveolar and lingual nerves during mandibular dental procedures. Emphasizing the significance of diagnostic tools, the review amalgamates existing knowledge to offer a comprehensive overview.

MATERIALS AND METHODS

A literature search across PubMed, Embase, and Cochrane Library informed the analysis.

RESULTS

Traumatic injuries often lead to hypo-/anesthesia and neuropathic pain, impacting individuals psychologically and socially. Diagnosis involves thorough anamnesis, clinical-neurological evaluations, and radiographic imaging. Severity varies, allowing for conservative or surgical interventions. Immediate action is recommended for reversible causes, while surgical therapies like decompression, readaptation, or reconstruction yield favorable outcomes. Conservative management, utilizing topical anesthesia, capsaicin, and systemic medications (tricyclic antidepressants, antipsychotics, and serotonin-norepinephrine-reuptake-inhibitors), proves effective for neuropathic pain.

CONCLUSIONS

Traumatic nerve injuries, though common in dental surgery, often go unrecorded. Despite lacking a definitive diagnostic gold standard, a meticulous examination of the injury and subsequent impairments is crucial.

CLINICAL RELEVANCE

Tailoring treatment to each case's characteristics is essential, recognizing the absence of a universal solution. This approach aims to optimize outcomes, restore functionality, and improve the quality of life for affected individuals.

Strategies for Avoiding Typical Drug-Drug Interactions and Drug-Related Problems in Patients with Vascular Diseases

Background and objectives: Drug-drug interactions and drug-related problems in patients with vascular diseases are common. To date, very few studies have focused on these important problems. The aim of the present study is to investigate the most common drug-drug interactions and DRPs in patients with vascular diseases. Materials and Methods: The medications of 1322 patients were reviewed manually in the time period from 11/2017 to 11/2018; the medications of 96 patients were entered into a clinical decision support system. Potential drug problems were identified, and a read-through consensus was reached between a clinical pharmacist and a vascular surgeon during the clinical curve visits; possible modifications were implemented. The focus was on additional dose adjustment and drug antagonization on drug interactions. Interactions were classified as contraindicated/high-risk combination (drugs must not be combined), clinically serious (interaction can be potentially life-threatening or have serious, possibly irreversible consequences), or potentially clinically relevant and moderate (interaction can lead to therapeutically relevant consequences). Results: A total of 111 interactions were observed. Of these, 6 contraindicated/high-risk combinations, 81 clinically serious interactions, and 24 potentially clinically relevant and moderate interactions were identified. Furthermore, 114 interventions were recorded and categorized. Discontinued use of the drug (36.0%) and drug dose adjustment (35.1%) were the most common interventions. Mostly, antibiotic therapy was continued unnecessarily (10/96; 10.4%), and the adjustment of the dosage to kidney function was overlooked in 40/96; 41.7% of the cases. In the most common cases, a dose reduction was not considered necessary. Here, unadjusted doses of antibiotics were found in 9/96, 9.3% of the cases. Notes for medical professionals summarized information that did not require direct intervention but rather increased attention on the part of the ward doctor. It was usually necessary to monitor laboratory parameters (49/96, 51.0%) or the patients for side effects (17/96, 17.7%), which were expected with the combinations used. Conclusions: This study could help identify problematic drug groups and develop prevention strategies for drug-related problems in patients with vascular diseases. A multidisciplinary collaboration between the different professional groups (clinical pharmacists and surgeons) might optimize the medication process. Collaborative care could have a positive impact on therapeutic outcomes and make drug therapy safer for patients with vascular diseases.

[Interdisciplinary aspects of oral anticoagulation with NOACs in atrial fibrillation]

Stroke prophylaxis with non-vitamin K-dependent oral anticoagulants (NOAKs) in patients with non-valvular atrial fibrillation (nvVHF) is now firmly established in routine clinical practice. The definition of nvVHF includes the absence of a mechanical heart valve and AF not associated with moderate- or high-grade mitral valve stenosis. The management of oral anticoagulation (OAC) requires a high degree of interdisciplinarity. Not least for this reason, uncertainties are repeatedly observed in practice, which can have far-reaching consequences for the individual patient. For this reason, a committee consisting of representatives from general medicine, geriatrics, cardiology, nephrology and neurology has gathered to identify aspects of practical relevance from the various disciplines and to jointly develop practical guidelines to improve therapy safety for patients in everyday life.

Calculated parenteral initial treatment of bacterial infections: Economic aspects of antibiotic treatment

This is the seventeenth chapter of the guideline "Calculated initial parenteral treatment of bacterial infections in adults - update 2018" in the 2nd updated version. The German guideline by the Paul-Ehrlich-Gesellschaft für Chemotherapie e.V. (PEG) has been translated to address an international audience. This chapter analyses economic aspects of antiinfective therapy. Any treatment decision is also a cost decision. In this chapter the authors particularly analyse whether or not there is evidence that certain clinically effective strategies as Antimicrobial Stewardship programs (AMS), guideline adherent initial therapy, early diagnostics, De-escalation, sequence therapy or therapeutic drug monitoring also have benficial economic effects. These can be direct savings or shortening of length of stay to free resources.

[Current strategies against multi-drug resistant organisms]

The global spread of multi-drug resistant organisms (MDRO) is a major threat to public health. Fighting MDRO spread requires a multi-faceted approach as summarized in the German Antibiotic Resistance Strategy (DART). In the hospital, this includes antibiotic stewardship concepts and strict infection control measures. Treatment of MDRO is sophisticated. Within the last years, several antibiotics with activity against MRSA were launched and facilitate an individual therapy according to site of infection and co-morbidities. In contrast, novel antibiotics against carbapenemase producing Gram-negatives are still lacking. Current studies have shown, that a colistin-based combination treatment can improve the prognosis in these patients. The following article reviews MDRO definitions, burden of disease, treatment options and general strategies against MDRO.

[Perioperative approach to restless legs syndrome]

Restless legs syndrome (RLS) is one of the most common neurological disorders. The key feature is the urge to move, especially in the legs. New onset RLS can develop perioperatively or an existing RLS can be exacerbated. Severe insomnia, forced immobilization and acute iron deficiency are common trigger factors. Medicinal treatment can also be an important triggering or exacerbating factor. Drugs with dopamine antagonistic, serotonergic and opioid antagonistic effects should be avoided. The long-term medicinal treatment should be terminated as quickly as possible and if necessary bridged non-orally. For diseases which can be associated with secondary RLS a provocation or an exacerbation of RLS should be taken into consideration. This is particularly true for Parkinson's disease, diabetes mellitus, terminal renal insufficiency, spinal cord lesions and pregnancy. So far, there is not sufficient evidence that any form of anesthesia has a negative influence on RLS.

Cost effectiveness of enoxaparin as prophylaxis against venous thromboembolic complications in acutely ill medical inpatients: modelling study from the hospital perspective in Germany

OBJECTIVE

To estimate, from the hospital perspective in Germany, the cost effectiveness of the low-molecular-weight heparin (LMWH) subcutaneous enoxaparin sodium 40 mg once daily (ENOX) relative to no pharmacological prophylaxis (NPP) and relative to subcutaneous unfractionated heparin (UFH) 5,000 IU three times daily (low-dose UFH [LDUFH]). Each is used in addition to elastic bandages/compression stockings and physiotherapy in the prevention of venous thromboembolic events (VTE) in immobilised acutely ill medical inpatients without impaired renal function or extremes of body weight.

METHODS

The incremental cost-effectiveness ratios (ICERs) of the 'additional cost for ENOX per clinical VTE avoided versus NPP' and 'additional cost for ENOX per episode of major bleeding avoided versus LDUFH' were chosen as target variables. The target variables were quantified using a modelling approach based on the decision-tree technique. Resource use during thromboprophylaxis, diagnosis and treatment of VTEs, episode of major bleeding and secondary pneumonia after pulmonary embolism (PE) was collected from a hospital survey. Costs were exclusively those to hospitals incurred by staff expenses, drugs, devices, disposables, laboratory tests and equipment for diagnostic procedures. These costs were determined by multiplying utilised resource items by the price or tariff of each item as of the first quarter of 2003. Safety and efficacy values of the comparators were taken from the MEDENOX (prophylaxis in MEDical patients with ENOXaparin) and the THE-PRINCE (THromboEmbolism-PRevention IN Cardiac or respiratory disease with Enoxaparin) trials and from a meta-analysis. The evaluation encompassed 8 (6-14) days of thromboprophylaxis plus time to treat VTE and episode of major bleeding in hospital. Point estimates of all model parameters were applied exclusively in the base-case analysis.

RESULTS

There were incremental costs of euro 1,106 for ENOX per clinical VTE avoided versus NPP (1 euro approximately equals 1.07 US dollars; average of the first quarter of 2003). ENOX dominated LDUFH: cost savings of euro 55,825 were obtained and 7.7 episodes of major bleeding were avoided by ENOX compared with LDUFH, each per 1000 patients. In comprehensive sensitivity analyses, the robustness of the model and its results was shown.

CONCLUSIONS

Results of this evaluation suggest that, in immobilised acutely ill medical inpatients, ENOX may offer hospitals in Germany a very cost-effective option for thromboprophylaxis compared with NPP and a cost-saving alternative compared with LDUFH.

Intravenous and oral antibiotics in respiratory tract infection: an international observational study of hospital practice

BACKGROUND

Hospitalised patients with respiratory tract infections (RTI) frequently receive intravenous (i.v.) antibiotics followed by a short course of oral treatment.

OBJECTIVES

To observe antibiotic use in hospitals in Germany, Spain, France, Italy and the UK and the reasons for choosing the i.v. route and switching to oral treatment.

METHODS

Research pharmacists sought the opinions of physicians and senior nurses in the completion of a semi-structured questionnaire on the treatment of RTI with i.v. antibiotics. Questions focussed on antimicrobials of choice, reasons for choosing i.v., reasons for changing to oral administration, and duration of treatment.

RESULTS

This study recruited 796 patients with RTI, usually pneumonia. Prescribing patterns varied widely between the five hospitals. Accepted clinical criteria were only commonly cited in Germany, Spain and the UK as reasons for choosing the i.v. route at the beginning of the study. These were more commonly cited at the time of switch, although other criteria such as improved condition, were other significant reasons. The mean duration of i.v. treatment ranged from 4 days in the UK to 10 days in Italy, where most patients received the full course of treatment by the i.v. route. Unlike the other hospitals studied, the few patients in Italy who were switched to another form of treatment were as likely to receive intramuscular as oral administration (13% and 11%, respectively).

CONCLUSIONS

The practice of and reasons for prescribing i.v. antibiotics varied in the hospitals studied. Objective clinical criteria were inconsistently cited as reasons for administering i.v. antibiotics and in general these reasons were unrelated to those given for the switch from i.v. to oral administration. In order for guidelines for switching from i.v. to oral antimicrobials to be routinely employed, explicit physiological criteria need to be recorded in a routine fashion. Closer co-operation between pharmacists and physicians may help in developing and implementing guidelines at a local level.

A contribution to the knowledge of the so-called pyloric band ("double pylorus")

Two new cases of patients with so called muscular pyloric band ("double pylorus") are reported. Both possible genetic mechanisms of this malformation are discussed in detail: primary or congenital, and secondary or acquired by inflammation. After analysis of the hitherto related cases, the opinion is expressed that the so called pyloric band represents a congenital malformation. According to the authors, the striking frequency of simultaneous occurrence of pyloric band and ulcers does not necessarily favour the theory of inflammatory genesis. The accompanying ulcer seems rather to be a "second disease" in the sense of Rossle (1913), manifesting itself at a locus minoris resistentiae.
