Autoimmune hepatitis (AIH) is a non-contagious, chronic, inflammatory autoimmune disease in which one's own immune system attacks healthy, normal hepatic cells. The exact cause of AIH is unknown; however, the combination of genetic, environmental (eg, drugs and natural infection) and immunological factors may lead to AIH. AIH may also be potentiated with the use of vaccines: this case reports one such event following immunisation, along with 1 year of follow-up. A female patient in her late 20s presented to the hospital with yellowish discolouration of eyes, urine and stools. Her medical history revealed that she had been vaccinated with the first dose of a COVID-19 vaccine 10 days earlier. She had a history of asymptomatic COVID-19 infection 3 months ago and a history of chronic analgesic consumption for migraine. She was diagnosed as having AIH through extensive clinical and laboratory workup. This case may be an immediate enhancement of a hidden autoimmune disorder triggered by the vaccination. This adverse event following immunisation has an adequate temporal relationship with her COVID-19 vaccine. The causality can be categorised as 'indeterminate' and may be considered as a potential signal following COVID-19 vaccination.

: With more and more cases emerging outside central and west African countries, where the disease is endemic, the World Health Organization (WHO) has recently declared human monkeypox a Public Health Emergency of International Concern. Typical symptoms of the disease include fever, myalgia, and lymphadenopathy followed by a rash, but other symptoms may occur. Immunocompromised patients, including patients with uncontrolled Human Immunodeficiency Virus (HIV) infection, may be at risk for more severe courses. We present the case of a 30-year-old male patient of Brazilian descent with monkeypox. Initial symptoms were fever and general discomfort, with painful pharyngitis and tonsillitis and finally a papular rash of the anogenital area as the disease progressed. The presumed date of infection was a sexual contact with an unknown male eight days before the first symptoms occurred. The patient had a known and controlled HIV infection. The main reason for the initial presentation at the hospital was painful pharyngitis and tonsillitis, limiting food intake. Monkeypox infection was confirmed via PCR testing from a swab sample of cutaneous lesions. Adequate systemic and local analgesia enabled oral food uptake again. Antiviral therapy with Tecovirimat was not administered due to the stable immune status of the patient and the mild clinical symptoms. To cover a possible bacterial superinfection or Syphilis infection of the tonsil, antibiotic therapy with Ceftriaxone was added. Several days after presentation, the inflammation of the pharynx resolved and was followed by non-painful mucosal peeling. The patient was followed up with telephone calls and reported a complete recovery. The skin lesions were completely dried out 18 days after the first symptoms. Painful pharyngitis and tonsillitis can be rare early symptoms of monkeypox, which is highly relevant in everyday clinical practice. Particularly in patients with risk factors for monkeypox infection, further clinical and microbiologic testing for monkeypox should be performed if there is a clinical presentation with pharyngitis and tonsillitis.

BACKGROUND Patients after organ transplantation are, due to chronic immunosuppression, prone to have many cutaneous adverse events, both infections and neoplasms. Studies show that some groups of patients under chronic immunosuppression are prone to develop demodicosis. The significance of demodicosis in the population of organ transplant recipients has not been established yet. CASE REPORT We present 4 cases of patients with multiply dermatological complications of immunosuppression, in which one of them is demodicosis. The presented symptoms were itch, pustules, papules, and/or telangiectasias. Age of patients varied from 64 to 79 years old. Time between transplantation and diagnosis of demodicosis varied from 6 to 10 years. Other dermatological problems that appeared were basal cell carcinoma, actinic keratosis, and seborrheic keratosis. Patients showed complete resolution after treatment with topical ivermectin 10 mg/g and topical permethrin 50 mg/g. However, the medications were prolonged to 16 weeks in 1 case to reduce persistent papules and telangiectasias. The therapy did not cause any complications or disruptions in function of transplanted kidneys in any of reported patients. CONCLUSIONS Demodicosis may have a significant role in the group of infections that organ transplant recipients are prone to, and may co-exist with other dermatological diseases, including neoplasms. However, larger studies in the field are needed.

Abdominal pain is a common reason for presentation in the emergency department and for calling emergency medical services. The complexity of abdominal pain also influences the analgesia strategy. However, there are almost no data on the use of ketamine for abdominal pain. This study aims to analyze the safety and efficacy of using ketamine as an analgesic for abdominal pain. In a retrospective analysis of prehospital patient data within the framework of quality assurance, all cases with ketamine administered by paramedics as analgesia for abdominal pain were analyzed in terms of pain reduction and patient safety and also compared with other analgesic drugs including fentanyl, morphine, and metamizole. From 01/01/2018 to 11/24/2021, 129 datasets were analyzed. The mean patient age was 50 ± 19 years (19-90 years), with 47.3% (n = 61) women. The application of fentanyl was documented as a monotherapy in 10.9% (n = 14), morphine in 2.3% (n = 3), metamizole in 34.1% (n = 44), and ketamine in 52.7% (n = 68) of cases. The pain relief of fentanyl, metamizole, and ketamine differed significantly from each other (p < 0.001), with fentanyl and ketamine being comparable. Looking at the quality assurance definition of successful analgesia (pain on handover NRS < 5 or pain reduction ≥ 2 points), successful analgesia was shown in 92.9% (n = 13) of cases for fentanyl, in 65.9% (n = 44) for metamizole, and 92.6% (n = 68) for ketamine (p < 0.001). Adverse events were not observed in patients treated with ketamine. Analgesia is an important goal in the treatment of patients with abdominal pain. With ketamine, analgesia comparable to fentanyl can be achieved. Ketamine appears to be a safe and effective option for the treatment of patients with abdominal pain in emergency medicine.Trial registration number DRKS00027343, date of registration: 09.12.2021, retrospectively registered.

To evaluate the effectiveness and safety of transcatheter arterial embolization(TAE) for chronic Achilles tendinopathy(AT) refractory to conservative treatment MATERIALS AND METHODS: This retrospective study included 20 patients(12 males and eight females with mean age of 30.3 years) who received TAE using imipenem/cilastatin sodium(IPM/CS) for refractory chronic AT from May 2019 to April 2021. Nine patients had bilateral involvement. Total 29 procedures were performed(8 procedures for nonathletes, 21 procedures for athletes). If feasible, embolization was performed superselectively at arterial branch demonstrating hypervascular staining, early venous drainage and/or supplying pain site noted using radiopaque marker. The visual analogue scale(VAS, 0-10) score was used to assess pain symptom at baseline and during follow-up period (1 day; 1 week; 1, 3, and 6 months; and open period). The clinical success rate was defined as decrease of more than 50% in the VAS score at 6 months when compared to the baseline.

Subcutaneous emphysema (SCE) of the head, neck and mediastinum most commonly arises due to penetrating trauma and iatrogenic events facilitating air entry into these spaces [1]. Spontaneous SCE can emerge due to a pressure gradient between the intra-alveolar air and surrounding structures, causing alveolar rupture and dissection of the peribronchovascular sheath. This is known as the Macklin effect. Potential consequences include pneumomediastinum, pneumothorax, facial emphysema and pneumoracchis [1]. We aim to describe a case of SCE in a 21-year-old female presenting to the emergency department (ED) after weight training. A 21-year-old female presented to the ED with a sore throat and dysphagia after weight lifting in the gym 6 h earlier. Training involved repeat Valsalva manoeuvres. She experienced sharp pain with onset over an hour, worse with swallowing. She had a history of gastro-oesophageal reflux disease. Vital signs, local examination and systemic examination were unremarkable. The diagnosis was made with soft tissue neck X-ray, demonstrating emphysema within the prevertebral space extending from the skull base to the first thoracic vertebra (Fig. 1). Her chest X-ray showed no pneumothorax or pneumomediastinum. No intervention was required beyond analgesia, and she was discharged from the ED. She was advised to avoid heavy lifting and diving. A follow-up radiograph showed resolution of the SCE. This case is an important rare entity and highlights for clinicians that pain after physical exercise may involve injuries extending beyond the area directly trained.

Type 2 diabetes mellitus (T2DM) is a highly heterogeneous chronic disease with different pathophysiological and genetic characteristics affecting its progression, associated complications and response to therapies. The advances in deep learning (DL) techniques and the availability of a large amount of healthcare data allow us to investigate T2DM characteristics and evolution with a completely new approach, studying common disease trajectories rather than cross sectional values. We used an Kernelized-AutoEncoder algorithm to map 5 years of data of 11,028 subjects diagnosed with T2DM in a latent space that embedded similarities and differences between patients in terms of the evolution of the disease. Once we obtained the latent space, we used classical clustering algorithms to create longitudinal clusters representing different evolutions of the diabetic disease. Our unsupervised DL clustering algorithm suggested seven different longitudinal clusters. Different mean ages were observed among the clusters (ranging from 65.3±11.6 to 72.8±9.4). Subjects in clusters B (Hypercholesteraemic) and E (Hypertensive) had shorter diabetes duration (9.2±3.9 and 9.5±3.9 years respectively). Subjects in Cluster G (Metabolic) had the poorest glycaemic control (mean glycated hemoglobin 7.99±1.42%), while cluster E had the best one (mean glycated hemoglobin 7.04±1.11%). Obesity was observed mainly in clusters A (Neuropathic), C (Multiple Complications), F (Retinopathy) and G. A dashboard is available at dm2.b2slab.upc.edu to visualize the different trajectories corresponding to the 7 clusters.

Hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitors might improve renal anemia maintaining fewer cardiovascular complications. However, its safety and efficacy, as well as its impact on inflammatory biomarkers, in heart failure patients remain unknown. We initiated HIF-PH inhibitors in 13 patients with chronic heart failure and renal anemia (median age 77 years, median estimated glomerular filtration rate 24.9 mL/min/1.73m) between September 2021 and February 2022. There were no drug-related complications, except for a patient who had a headache and hot flash, resulting in discontinuation of HIF-PH inhibitor at 3 months. Among 10 patients who continued HIF-PH inhibitors for over 3 months, hemoglobin levels increased significantly (median from 9.6 g/dL to 10.7 g/dL, p = 0.004) and hepcidin-25 levels tended to decrease (median from 11.5 ng/mL to 3.0 ng/mL, p = 0.294) at 3-month follow-up. In conclusion, HIF-PH inhibitors might be safe and effective for the treatment of renal anemia in patients with chronic heart failure.

In a companion paper we examined whether combinations of K7 channel openers (Retigabine and Diclofenac; RET, DIC) could be effective modifiers of deep tissue nociceptor activity; and whether such combinations could then be optimized for use as safe analgesics for pain-like signs that developed in a rat model of GWI (Gulf War Illness) pain. In the present report, we examined the combinations of Retigabine/Meclofenamate (RET/MEC) and Meclofenamate/Diclofenac (MEC/DIC). Voltage clamp experiments were performed on deep tissue nociceptors isolated from rat DRG (dorsal root ganglion). In voltage clamp studies, a stepped voltage protocol was applied (-55 to -40 mV; V=-60 mV; 1500 msec) and K7 evoked currents were subsequently isolated by Linopirdine subtraction. MEC greatly enhanced voltage dependent conductance and produced exceptional maximum sustained currents of 6.01 ± 0.26 pA/pF (EC: 62.2 ± 8.99 μM). Combinations of RET/MEC, and MEC/DIC substantially amplified resting currents at low concentrations. MEC/DIC also greatly improved voltage dependent conductance. In current clamp experiments, a cholinergic challenge test (Oxotremorine-M, 10 μM; OXO), associated with our GWI rat model, produced powerful action potential (AP) bursts (85 APs). Optimized combinations of RET/MEC (5 and 0.5 μM) and MEC/DIC (0.5 and 2.5 μM) significantly reduced AP discharges to 3 and 7 Aps, respectively. Treatment of pain-like ambulatory behavior in our rat model with a RET/MEC combination (5 and 0.5mg/kg) successfully rescued ambulation deficits, but could not be fully separated from the effect of RET alone. Further development of this approach is recommended.
