RESUMEN
Despite treatment with levothyroxine, hypothyroidism and autoimmune thyroiditis (AIT) may be associated with reduced quality of life (QoL), an enigmatic condition referred to as "syndrome T". Peripheral neuropathy, described in untreated thyroid disease, could be a contributing mechanism. We analysed autonomic and somatosensory function in 29 patients with AIT and treated hypothyroidism and 27 healthy volunteers. They underwent heart rate variability (HRV) analysis and quantitative sensory testing (n = 28), comprising 13 parameters of small and large nerve fibre function and pain thresholds. Autonomic cardiovascular function was assessed in rest, deep respiration and orthostasis. Additionally, biomarkers for autoimmunity and thyroid function were measured. Anxiety, depression and QoL were assessed using validated questionnaires. 36% of the patients showed at least one sign of somatosensory small or large fibre dysfunction. 57% presented with mild hyperalgesia to at least one stimulus. Several markers of autonomic function and some detection thresholds were related to the antibody titres. Anxiety, depression scores and QoL correlated to antibody titres and HRV measures. Autonomic and somatosensory dysfunction indicate that in treated hypothyroidism and AIT a subgroup of patients suffers from neuropathic symptoms leading to impaired QoL. Additionally, mild hyperalgesia as a possible sensitisation phenomenon should be considered a target for symptomatic treatment.

BACKGROUND: Chronic pain after trauma and surgery is a long-term complication. Its relevance for patients within the workers' compensation rehabilitation process has not been adequately investigated. OBJECTIVES: Initial evaluation of frequency of chronic pain after occupational accidents. METHODS: In 2017, surgical inpatients (18-65 y) treated in a tertiary hospital were asked about chronic pain arising from an occupational trauma recognized by statutory occupation insurance (interval 2.8±6.9 years), regardless of care received, first at the time of hospitalization and then by telephone interview 6 months later. The focus was on patients with a work-related trauma (A) within the past month or (B) >6 months. PRIMARY OUTCOME: frequency of work trauma-related chronic pain (>6 months) at the initial interview (point prevalence), secondary outcomes: frequency of chronicity at 6 months (A) and persistence of chronic pain (B). Tertiary outcomes: ability to work, occupational injury classification, burden based on pain intensity, localization, and medication, functional deficits due to the existence of chronic pain, and comorbidity. RESULTS: Out of 415 patients included in the survey, 85% (160/188) reported accident-related chronic pain (predominantly moderate to highly severe in intensity, localized at joints and bones). 90% (131/145) also reported this pain six months later. 67% (64/96) reported chronic pain for the first time. Patients with chronic pain at follow-up (281/369) were less likely to return to work (p=0.003), required analgesics in 60%, were more often comorbid (p<0.002) and had greater functional deficits (p<0.002). CONCLUSION: Despite the preliminary nature of the data, chronic pain seems to be common after occupational trauma and negatively affects the recovery of work ability in the long term. Based on the present observational data, a further differentiated re-evaluation of prospective data considering therapeutic measures is strongly recommended.

OBJECTIVES: Inhalative anesthesia is of common use, but is generally known to potentiate postoperative nausea and vomiting (PONV). With an internal change of anesthesia regimen from total intravenous anesthesia (TIVA) to isoflurane (in terms of myocardial protection) in cardiac anesthesia a higher incidence of PONV was to be expected. Therefore, we evaluated the incidence of PONV after the simultaneous implementation of PONV prophylaxis. METHODS: The incidence of PONV, prospectively assessed in 197 cardiac surgery patients (68 y ± 10.4, 66.5% male) having isoflurane plus dual PONV prophylaxis with dexamethasone and droperidol, was compared with previous data of 190 controls (67 y ± 9.6, 71% male) having TIVA without and with single or dual PONV prophylaxis (n = 64 dexamethasone and droperidol, n = 25 dexamethasone, n = 101 only TIVA), and the Apfel-scoring (0-4 depending on PONV-risk). DRKS00014275. Statistics: Chi2-test, p < .05 (Bonferroni). RESULTS: The incidence of PONV under isoflurane with antiemetic prophylaxis was 20.8% (95% confidence interval (CI) 15.4; 27.4) compared to 30.5% (95%CI 24; 37.6) under TIVA (p = .029; dexamethasone and droperidol 23.4% (95%CI 13.8; 35.7); dexamethasone 32% (95%CI 14.9; 53.5); only TIVA 34.7% (95%CI 25.5; 44.8)), but was not lower in high-risk patients than predicted according to Apfel-scoring 4 (71.4 vs. 78%). CONCLUSION: In cardiac anesthesia, the use of isoflurane is not at the expense of PONV when using a risk-independent two-drug-prophylaxis. It is even beneficial resulting surprisingly in a lower incidence of PONV than under TIVA unless with and without prophylaxis. Patients with the highest risk for PONV and receiving isoflurane should receive a third antiemetic prophylactic drug.

PURPOSE: Intensive care unit-acquired weakness (ICUAW) can manifest as muscle weakness or neuropathy-like symptoms, with diagnosis remaining a challenge. Uncertainties surround the long-term cause and sequelae. Therefore, the purpose was to assess incidence, time course and long-term influence on quality of life (QoL) of symptoms in ICU survivors. METHODS: After ethical approval and registration (www.drks.de: DRKS00011593), in a single-center cohort study all patients admitted to the ICU in 2007-2017 in a German university hospital were screened. Out of 1,860 patients (≥7d ICU care including ventilation support for ≥72 h, at least 6mo-10y after ICU) 636 were deceased, 912 survivors were contacted. RESULTS: 149 former patients (age: 63.5 ± 13.1y; males: 73%; duration in ICU: 20.8 ± 15.7d; duration of ventilation: 16.5 ± 13.7 h; time post-ICU: 4.4 ± 2.7y, 5-10y: 43%) consented to be interviewed concerning occurrence, duration, recovery and consequences of ICUAW-associated muscle weakness or neuropathy-like symptoms after ICU. In 75% at least 1 persistent or previous symmetrical symptom was reported (myopathy-like muscle weakness: 43%; neuropathy-like symptoms: 13%; both: 44%) and rated as incidence of ICUAW. However, only 18% of participants had received an ICUAW diagnosis by their physicians, although 62% had persistent symptoms up to 10y after ICU (5-10y: 46%). Only 37% of participants reported a complete recovery of symptoms, significantly associated with an initially low number of symptoms after ICU (p < 0.0001), myopathy-like symptoms (p = 0.024), and younger age at the time of ICU admission (55.7 ± 13.1 vs. 62.6 ± 10.6y, p < 0.001). ICUAW still impaired the QoL at the time of the interview in 74% of affected survivors, with 30% reporting severe impairment. CONCLUSION: ICUAW symptoms were disturbingly common in the majority of long-term survivors, indicating that symptoms persist up to 10y and frequently impair QoL. However, only a small number of patients had been diagnosed with ICUAW.

BACKGROUND: Neuropathic pain consistently presents a significant therapeutic challenge. Topically applied analgesics have the advantage of showing low systemic side effects, but data on long-term effectiveness are lacking. Consequently, interviews were carried out with all patients being treated with topical analgesics in hospital. METHODS: Ethics 16-5690, German Clinical Trials Register (DRKS) 00011877. Between 2008 and 2017 a total of 265 patients were treated at least once with either capsaicin 8% (C), lidocaine 5% (L) and/or perineural botulinum toxin type A (B). From this sample, 205 patients (77%) were interviewed by telephone for feedback on pain reduction (first/last treatment: low/moderate/very good), the possible reduction of analgesic prescription and if applicable the reasons for discontinuation of use (time of interview C: 26⯱ 19 months, L: 61⯱ 23 months, B: 11⯱ 6 months after start). Further pretreatment data and diagnoses were obtained from the in-house documentation system. Responders or long-term responders were defined as patients with at least one moderate pain reduction after the first or last treatment, as long as the effect was adequately maintained. RESULTS: In all treatment groups (56⯱ 13 years, 62% male, C: 80, L: 84, B: 58 patients) patients with a long history of pain (C: 60⯱ 73 months, L: 59⯱ 66 months, B: 67⯱ 71 months) and high pain intensity (numeric rating scale, NRS, C: 7⯱ 2, L: 7⯱ 2, B: 6⯱ 2), were predominant. The highest primary and long-term responder rates were exhibited by L (57%/60%, B: 52%/37%, C: 23%/15%). With B, long-term responders were most frequently able to reduce analgesic use (74%, C: 58%, L: 38%). DISCUSSION: Despite the long duration of the disease, the most used off-label topical drugs L and B demonstrated a high primary response rate (in contrast to C), with most benefiting from long-term treatment.

Objectives: Subcutaneous injection of botulinum toxin-A (sBONT-A) is a novel treatment for peripheral neuropathic pain. While its analgesic effects are well documented, this treatment is often not comfortable and fails in patients who show signs of sensory loss but rarely allodynia. There are some case reports about perineural BONT-A injection (pBONT-A) which could be an alternative approach. Here we present a retrospective, open label case series of pBONT-A's efficacy and safety regarding neurological consequences involving changes in somatosensory profiles of both responders and non-responders. Methods: Sixty patients (53 ± 13years, 77% males) with PNI were treated with pBONT-A after a test injection with a local anesthetic, which prompted distinctive pain relief. Quantitative sensory testing (QST; DFNS protocol) and pain intensity were assessed before and ≥7 days post pBONT-A injection. Definition of response: satisfactory pain reduction of ≥30% NRS (numerical rating scale: 0 = no pain, 10 = worst pain) for ≥4 days. Statistics: Paired t-test, Mann-Whitney U-test, χ2 test. Results: A temporary weak paresis in one case was clinically verified. The QST -parameters remained unchanged, but patients with more frequent hyperalgesia signs reported less analgesia (p = .04). The pBONT-A injection prompted pain relief by 24.8% (NRS: 6.0 ± 1.7 vs. 4.5 ± 2.1; p < .0001); 57% (n = 34) were responders (NRS: 6.0 ± 1.6 vs. 3.4 ± 1.6, relief of 43.4%; p < .0001). Based on these results, we suggest that future parallel design trials on pBONT-A need to include at least 84 patients. Discussion: Ultrasound-guided pBONT-A injection seems to be a safe treatment leading to a sufficient pain relief for some months without sensory changes. Surprisingly, pBONT-A showed a pronounced analgesic effect also in patients without signs of hyperalgesia.

OBJECTIVE: Controlled opioid withdrawal is recommended for patients with chronic noncancer pain (CNCP) with insufficient pain reduction or intolerable side effects while on opioid treatment. Few studies have investigated the management of opioid withdrawal (OW). Most common are protocols with an individualized starting dosage (ISD), calculated from the last opioid intake. After two cases of overdose, we introduced a novel withdrawal protocol using a low fixed starting dosage (FSD) for safety reasons. The present study compares the intensity of withdrawal symptoms using the Subjective Opioid Withdrawal Scale (SOWS) and incidences of serious adverse events (SAE) and dropouts in each taper schedule in 195 CNCP patients with OW in an inpatient facility. METHODS: Two protocols were compared: FSD (2014-2016): N = 68, starting dose: 90 mg morphine/d; and ISD (2010-2014): N = 127, starting dose: 70% of the patient's daily morphine equivalent dose (MED). Outcome criteria: primary: mean daily SOWS score during the first 10 days (16 questions, daily score 0-64); secondary: change in pain intensity on a numeric rating scale (0-10), rate of dropouts and SAEs. Statistics: Student test, Mann-Whitney U test, chi-square test, analysis of variance, P < 0.05. RESULTS: The mean daily SOWS score was lower in the FSD group (14.9 ± 9.4 vs 16.1 ± 10, P < 0.05) due to a lower rate of high-intensity withdrawal symptoms (12.4% vs 17.6%, P < 0.01), particularly in patients on >180 mg MED (9.7% vs 18.4%, P < 0.01). Pain intensity decreased after withdrawal, and the incidence of SAEs and dropouts was low in both groups. CONCLUSIONS: The FSD protocol provides a lesser burden of withdrawal symptoms and equal patient safety. It can be recommended for OW in CNCP patients.

Local osteopenia and altered bone metabolism are major complications of complex regional pain syndrome (CRPS), but quantitative assessment is difficult unless using X-ray or dual-energy X-ray absorptiometry. Ultrasound-based measurement of bone density (UBD) is a possible alternative but has never been used to detect unilateral disease such as CRPS. Therefore, the main outcome measure of this prospective study was the diagnostic utility of UBD in patients with lower-limb CRPS. Second, we compared the extent of unilateral and contralateral calcaneal bone density to that of other conditions with unilateral pain, general osteoporosis, and healthy subjects. Calcaneal osteodensitometry was bilaterally examined using ultrasound-based methodology. Bone mineral density values were converted to Z-scores based on age- and sex-dependent reference values. All patients completed a functional and an osteoporosis risk questionnaire. In patients with CRPS (n = 18), the bone mineral density values and Z-scores were significantly lower in both the affected (mean ± SD: 0.40 ± 0.08 and -1.1 ± 0.8, respectively) and nonaffected (0.46 ± 0.09 and -0.6 ± 0.9, respectively) limbs than in patients (n = 40) with other unilateral pain syndromes (affected: 0.51 ± 0.1 and -0.2 ± 1.1, respectively; nonaffected: 0.54 ± 0.11 and 0 ± 0.9, respectively) and healthy subjects (right side: 0.6 ± 0.1 and 0.1 ± 0.9, respectively). Conversely, in patients with known systemic osteoporosis, the Z-scores were lower bilaterally with smaller side-to-side differences than in those with CRPS (P < 0.05). Compared with subjects suffering from long-term CRPS (≥2.4 years), patients with shorter disease duration exhibited significantly lower Z-scores (P < 0.05). In conclusion, UBD revealed that CRPS is associated with both local and systemic alterations of bone metabolism.

Osteoporosis remains a major health concern due to high incidence of fragility fractures followed by higher mortality and morbidity. Implementation of guidelines for diagnosis and treatment of osteoporosis is critically discussed internationally. Aim of this study was to evaluate implementation of these guidelines regarding diagnosis and therapy of osteoporosis in a developed western country. We hypothesized that (a) prior diagnosis of osteoporosis in patients with low-energy fractures is higher than the estimated incidence and (b) diagnosis and therapy of osteoporosis in patients with prior low-energy fractures is higher than in patients without prior low-energy fractures. 399 patients >60 years suffering low-energy-fractures of their spine, femur, humerus or forearm between 03/2014 and 04/2015 were recruited in a German trauma center. All received a standardized interview. In 21% (84/399) of all patients, osteoporosis was diagnosed prior to current admission. 34% (136/399) suffered a prior risk-fracture after age of 50. Of these, only 54% (73/136) reported about following dual-energy X-ray absorptiometry (DXA) to test for decreased bone-marrow-density with positive results in 68% (50/73). 38% (19/50) of these patients with fragility fractures and prior osteoporosis diagnosis received anti-osteoporotic medication. 66% (263/399) of all patients had no prior risk-fracture and were tested for osteoporosis by DXA in 36% (95/263), leading to positive results in 34% (32/95). 44% (14/32) of these patients received anti-osteoporotic medication. Applying FRAX, 33% of all patients showed a calculated 10-year-risk >20% for suffering a major osteoporotic fracture. 61% (83/136) of patients with a prior fracture had a 10-year-risk >20% of which 47% (39/83) patients received no prior DXA. Although guidelines recommend diagnosis and treatment of patients with low-energy fractures, opportunity for early treatment following risk fractures seems rarely used. Expedient risk assessment is necessary to indicate further diagnostics and therapy of osteoporosis to ensure adequate and efficient treatment for osteoporotic fractures.

BACKGROUND: Propofol is recommended for sedation in gastrointestinal endoscopy (GE), but preliminary data suggest addictive potentials. OBJECTIVE: The objective of this article is to evaluate the frequency of predominantly euphoric reaction after GE and patients' subsequent reminiscences. METHODS: Eighty-two patients undergoing elective GE under propofol sedation were enrolled in a prospective observational study. The grade of anxiety, expectation or relief about the examination's result and affective state in terms of cheerfulness, relaxation, activation, sedation and anxiety were surveyed using a numeric rating scale (1 to 10) immediately before (t1), after GE (t2) and seven days (t3) later. Statistics: hierarchical cluster analysis, heat map, χ2 test and paired t test. RESULTS: Mean propofol dosage was 264 ± 120 mg. Two clusters of mood changes emerged (t1 vs. t2). One (n = 46, 56.1%) was characterized by an unease reaction pattern with equal values regarding cheerfulness, relaxation and anxiety, while relaxation decreased; the other cluster showed a euphoric reaction pattern (n = 36, 43.9%) with markedly increased cheerfulness, relaxation and decreased anxiety. These effects intensified at recall (t3). Despite similar endoscopy results, euphoric cluster patients rated these more positively. CONCLUSION: Propofol induces euphoria in nearly half of the patients undergoing elective GE with persisting, even enhanced reminiscence (germanctr.de, trial number DRKS00011202).
