Abstract
Pancreatic ductal adenocarcinoma (PDAC) exhibits the highest incidence of perineural invasion among all solid tumors. The intricate interplay between tumors and the nervous system plays an important role in PDAC tumorigenesis, progression, recurrence, and metastasis. Various clinical symptoms of PDAC, including anorexia and cancer pain, have been linked to aberrant neural activity, while the presence of perineural invasion is a significant prognostic indicator. The use of conventional neuroactive drugs and neurosurgical interventions for PDAC patients is on the rise. An in-depth exploration of tumor-nervous system crosstalk has revealed novel therapeutic strategies for mitigating PDAC progression and effectively relieving symptoms. In this comprehensive review, we elucidate the regulatory functions of tumor-nervous system crosstalk, provide a succinct overview of the relationship between tumor-nervous system dialogue and clinical symptomatology, and deliberate the current research progress and forthcoming avenues of neural therapy for PDAC.

Abstract
In Germany, headache is one of the illnesses that most frequently leads to health impairments and to consultation with physicians. Even in children, headache is often associated with restricted activities of daily life. Nevertheless, the level of care for headache disorders is disproportionate to the medical needs. As a result, patients regularly use complementary and supportive therapeutic procedures. This review shows the procedures currently used for primary headache in childhood and adulthood, the methodological approaches and existing scientific evidence. The safety of the therapeutic options is also classified. These methods include physiotherapy, neural therapy, acupuncture, homeopathy, phytotherapy and the intake of dietary supplements. For children and adolescents with headaches, there are studies in the field of dietary supplements for coenzyme Q10, riboflavin, magnesium and vitamin D, which indicate specific effects in the reduction of headaches.

Abstract
BACKGROUND Complex regional pain syndrome (CRPS) affects 10-15% of patients following injuries (fractures, surgery) to the outer extremities and people after a stroke. The affected area hurts, is inflamed and lacks strength, while mobility and sensitivity are restricted. Complementary medicine as part of integrative medicine offers additional effective treatment options. RESEARCH QUESTION Complementary therapies that extend the guideline recommendations, demonstrate clinical evidence and/or are plausible are presented. RESULTS Mind-body medicine procedures (mindfulness, relaxation, yoga, Qi Gong, etc.) support the patient's self-efficacy and stimulate the vagus nerve as well as promoting the reduction of pain, depression and anxiety and improving quality of life. Phytotherapeutics such as turmeric or stinging nettle have an anti-inflammatory effect. Water treatments reduce pain, and acupuncture and neural therapy can be tried. CONCLUSIONS Integrative, complementary medical therapy options support the CRPS patient in coping with their disease and the related pain. These options can play an important role in the multimodal, interdisciplinary treatment of this disease.

Abstract
BACKGROUND Inflammatory and mechanical stimuli in tooth/jaw pathologies can have far-reaching consequences via trigeminal and autonomic circuitry and can cause systemic (e.g., autoimmune) diseases and pain conditions outside the tooth/jaw region. In addition to a case report, we also describe new pathophysiological findings. CASE REPORT We report on a patient with chronic, therapy-resistant neck pain whose cause lied in the tooth/jaw region, specifically, in wisdom teeth with space problems, and partially impacted. The tooth/jaw area itself was not painful; however, neck pain developed via the nucleus spinalis n. trigemini which extends into the cervical medulla. Surgical restoration of the wisdom teeth and subsequent neural therapy treatment of the extraction scars provided permanent pain relief. CONCLUSION In case of therapy-resistant neck pain (among others), it is worthwhile to look for pathologies in the dental/jaw area, possibly allowing for a causal therapy.

Abstract
BACKGROUND Localized vulvar pain (LVP) is a common condition among fertile women, with physical and psychosexual implications. Treatment is complex with limited benefits. Neural therapy is a regulatory therapy that uses injections of local anesthetics in low concentrations in specific points to treat different conditions. CASE PRESENTATION We present the cases of 5 women, ages 33-44 years, with LVP treated with procaine 0.5% injections in painful points. Complete relief from pain occurred in 2 patients, and significant improvement in 3. Only 1 or 2 sessions were required. Initial VAS score was ≥70 and decreased to ≤30 after the intervention. The improvement was maintained over time, with a minimum follow-up period of 6 months. None of the patients were able to have sex or use tampons due to pain, but they were able to resume after the intervention. CONCLUSIONS In this case series, local injections of procaine showed a favorable outcome. Future randomized clinical trials could help elucidate the role of this intervention in LVP.

Abstract
BACKGROUND In this study, we aimed to assess the effect of neural therapy in the prevention of post-tubal syndrome, which is the combination of dysmenorrhea, bloating, dyspareunia, heavy menstrual bleeding, chronic vaginitis, and cystitis, after elective bilateral tubal ligation with modified Pomeroy technique. MATERIAL AND METHODS In total, 113 patients who have undergone bilateral tubal ligation with modified Pomeroy technique between January 2016 and December 2018 in our clinic have been included. Postoperatively, patients were divided into two groups. One group received neural therapy (n = 52), and the other group did not receive neural therapy (control group, n = 61). Both groups were evaluated in terms of preoperative and postoperative symptoms. One year after surgery, patients' pain levels were evaluated using visual analog scale (VAS). RESULTS When both groups were compared in terms of symptoms, dysmenorrhea, dyspareunia, bloating, frequency of vaginitis, and cystitis per year and pain perception using VAS, the symptoms were significantly less in the neural therapy group. However, there was no difference between the groups in terms of the amount of menstrual bleeding. CONCLUSIONS Patients who received neural therapy showed less pain symptoms (dysmenorrhea and dyspareunia), and their VAS scores were lower when compared to the control group. Thus, we concluded that neural therapy is effective in the treatment of post-tubal syndrome.

Abstract
ANTECEDENTS AND OBJECTIVE Local infiltrations are second line therapy in the treatment of chronic low back pain, although their use is controversial in the literature. Our objective was to compare the effectiveness of 2 types of infiltration at the paravertebral lumbar level in two groups of patients diagnosed with low back pain: corticosteroids, and selective local anaesthetic administered using segmental neural therapy (SNT). MATERIAL AND METHODS Double-blind clinical trial in 55 patients diagnosed with low back pain in the neurosurgery department of the Hospital Central de la Defensa Gómez Ulla. Patients were randomised to 2 treatment groups to receive either paravertebral injections of corticosteroids or SNT. Outcomes were measured using a visual analogue scale, the Oswestry Disability Index, the Short Form-36, and patient satisfaction at the start of treatment (baseline) and at 3 and 12 months post intervention. RESULTS The combined treatment group showed a statistically significant improvement in Oswestry Disability Index at 3 months. The SNT group showed a statistically significant improvement in baseline visual analogue scale vs. visual analogue scale at 3 (1.398cm, p=0.001) and 12 months (0.791cm, p=0.007). No differences were observed in the remaining variables measured. The percentage of patients that would repeat the treatment was 81% and 83%, respectively. CONCLUSIONS Significant pain relief was achieved with SNT, and disability improved with the combined treatment. Although clinical improvement was limited, patients were satisfied. Local infiltrations should be considered as an alternative treatment for chronic low back pain. CLINICAL TRIAL REGISTRATION This clinical trial was registered at the European Union Clinical Trials Register with EUDRA-CT number 2015-001146-29.

Abstract
BACKGROUND The aim of this study was to explore the effect of neural therapy on pain and functionality in patients with low back pain due to piriformis syndrome. It also aimed to find out any possible links between the clinical changes and demographic features. METHOD One hundred and two patients were randomly divided into two groups (neural therapy and control). All patients were given stretching exercises for the piriformis muscle. The patients in the neural therapy group additionally received 6 sessions of neural therapy. The visual analog scale (VAS) and Oswestry Disability Index (ODI) were noted before and after the treatment in both groups. RESULTS The VAS and ODI improved in both groups. However, improvement of the VAS and ODI scores were more obvious in the neural therapy group. The changes of VAS and ODI values did not show any correlations with the demographic features. CONCLUSION After the neural therapy, the patients with low back pain due to piriformis syndrome may have improvement in both pain and functioning.

Abstract
Background Neural Therapy (NT) is a common complementary treatment approach using injections with short-acting local anesthetics to treat pain and chronic diseases. However, little is known about the underlying mechanisms and the domains of treatment response. This study therefore analyzed patient experiences following NT injections with procaine. Methods Maximum variation sampling was used to collect data from semi-structured interviews conducted with 22 hospital inpatients aged 59.6 ± 14.9 years (81.8% female). Each had multiple (9.4 ± 6.9) diagnoses. They were undergoing two weeks of integrative treatment, which included individualized NT. The interview data were analyzed in MAXQDA using qualitative content analysis. Results With injection, patients first described local anesthetic effects including temporary blocking of pain and increased local warmth. Second, patients reported on vegetative reactions frequently leading to turmoil within the body like initial aggravation of existing symptoms or the appearance of new, concealed or phantom symptoms. This often required the need for rest to deal with the treatment stimulus. As a third step, many patients could gain physical and emotional release and relief in symptoms, mood and functioning. Emotional release was often accompanied by weeping and initially overwhelmed affected patients with dissociated memories. However, in cases where patients were able to experience those memories with a new distance, a fourth step of integration was achievable. It included reframing processes as well as a gain in pain perception and body-awareness. As a possible fifth step, patients experienced improved mood, increased pain acceptance and empowerment. Adverse events of NT included pain from the injections, vegetative complaints and emotional turmoil that lasted for minutes or hours, with a maximum of two days. Conclusions Patients treated with procaine injections reported different psychophysiological outcomes contributing to the understanding of the mechanisms underlying NT. Further efficacy studies should separate specific NT from non-specific/placebo effects. Trial registration DRKS00004567.

Abstract
BACKGROUND The NECTAR-HF study evaluated safety and feasibility of vagal nerve stimulation (VNS) for the treatment of heart failure patients. The first six-month randomized phase of the study did not show improvement in left ventricular remodelling in response to VNS. This study reports the 18-month results and provides novel findings aiming to understand the lack of efficacy of VNS, including a new technique assessing the effects of VNS. METHODS Ninety-six patients were randomized 2:1 to active or inactive VNS for 6months, thereafter VNS was activated for all patients. The primary safety endpoint was 18-month all-cause mortality. RESULTS Ninety-one patients continued in the long-term evaluation with active VNS. The on-therapy survival estimate at 18months was 95% with a 95% one-sided lower confidence limit of 91%, (better than the predefined criterion). Left ventricular systolic volume decreased in the crossover group (VNS OFF→ON; 144±37 to 139±40, p<0.05) after VNS activation; LVESD (5.02±0.77 to 4.96±0.82, p>0.05) and LVEF (33.2±4.9 to 33.3±6.5, p>0.05) did not change. A new technique to detect subtle heart rate changes during Holter recordings, i.e. "heat maps", revealed that VNS evoked heart rate response in only 13/106 studies (12%) at 6 and 12months with active VNS. CONCLUSIONS Although a favourable long-term safety profile was found, improvements in the efficacy endpoints were not seen with VNS. A new technique for detecting acute heart rate responses to VNS suggests that the recruitment of nerve fibres responsible for heart rate changes were substantially lower in NECTAR-HF than in pre-clinical models.

Abstract
BACKGROUND The sympathetic nervous system has an important role in generating pain. Various pathomechanisms are involved that respond well to the application of local anesthetics (LA), for example to the stellate ganglion block (SGB). OBJECTIVES We wanted to know more about the effects of SGB on cardiovascular parameters. METHODS We included 15 healthy volunteers; another 15 healthy volunteers as a control group (sham injection of LA). In order to produce a more precise SGB, we employed only a small volume of LA (3mL), a LA with a lower permeability (procaine 1%), and a modified injection technique. Systolic and diastolic blood pressure (SBP, DBP), heart rate (HR), and echocardiographic parameters were recorded before and after SGB. We also investigated whether there are side differences (left and right SBG). RESULTS At baseline all parameters were within the normal range. After performing right and left SGB DBP significantly increased (on the right side from 68.73±8.61 to 73.53±11.10, p=0.015; on the left side from 70.66±13.01 to 77.93±10.40, p=0.003). In the control group no increase in DBP was observed. No side-specific differences were found, except a significant reduction in the maximum velocity of myocardial contraction during the systole with left-sided SGB. CONCLUSIONS Even with our methods we could not prevent the simultaneous occurrence of a partial parasympatholytic effect. For this reason, the SGB has only minor hemodynamic effects, which is desirable as it enhances the safety of the SGB.

Abstract
PURPOSE Pudendal nerve injection is used as a diagnostic procedure in the vulvar region and for therapeutic purposes, such as in vulvodynia. Here, we provide a new, easy-to-perform perineal injection technique. PATIENTS AND METHODS We analyzed 105 perineal injections into the pudendal nerve with a local anesthetic (LA), procaine in 20 patients. A 0.4 × 40 mm needle was handled using a stop-and-go technique while monitoring the patient's discomfort. The needle was placed 1-2 cm laterally to the dorsal introitus. After aspiration, a small amount of LA was applied. After subcutaneous anesthesia, the needle was further advanced step-by-step. Thus, 5 ml could be applied with little discomfort to the patient. Anesthesia in the pudendal target region was the primary endpoint of our analysis. RESULTS In 93 of 105 injections (88.6 %), complete perineal anesthesia was achieved with a single injection. 12 injections were repeated. These injections were excluded from the analysis. Severity of injection pain, on visual analog scale (VAS) from 0 to 100, was 26.8 (95 % CI 7.2-46.4). Age (β = 0.33, p < 0.01) and the number of previous injections (β = 0.35, p < 0.01) inversely correlated with injection pain. Injection pain and anesthesia were not affected by BMI, the number and the side of previous injections, or order of injection. A reversible vasovagal reaction was common, but no serious adverse effects occurred. CONCLUSION Perineal pudendal injection is an effective and safe technique for anesthesia in diagnostic (vulva biopsy) and therapeutic indications (pudendal neuralgia), and regional anesthesia in perinatal settings.
