This study was undertaken to evaluate efficacy of Actovegin in the composition of comprehensive therapy in patients presenting with post-thrombotic disease of lower extremities free from trophic disorders.

No clear guidelines exist for the management of phlegmasia cerulea dolens. This case report shows how a hybrid approach might be successful. It also shows how rare pathologies can combine to create a life- and limb-threatening condition. . A 75-year-old man, known for nephrotic syndrome currently under investigation, presented to the emergency department with a 24-hour history of left leg swelling followed by intense pain. The left lower limb showed a phlegmasia cerulean dolens. Renal function, coagulation profile, and inflammatory parameters were normal; D-Dimers 5,6 mg/L. The CT scan showed juxtarenal thrombosis of the hypoplastic IVC, involving both renal veins, reaching the left iliac-femoral-popliteal axis, with collateralization to the pelvic and mesenteric veins, associated with bilateral segmental pulmonary embolisms. A suspected left breast nodule was also found. Intravenous heparin was immediately administered, and urgent hybrid procedure with surgical thrombectomy and venous angiography and thromboaspiration, liberating the iliolumbar collaterals, was performed. A lateral leg fasciotomy was mandatory due to the phlegmasia cerulea. Postoperative Doppler US showed a good venous compressibility of the left leg. Thrombophilia screening was negative. The breast nodule was biopsied showing an invasive ductal carcinoma. The patient was discharged with oral rivaroxaban and indication for left mastectomy and oncological therapy with aromatase inhibitors.

A man in his 40s visited a facility with the chief complaint of abdominal pain;liver dysfunction was detected, and consequently, he was referred to our hospital for further examinations. His medical history was unremarkable. He used to drink alcohol (beer, 1500mL) every day. Magnetic resonance imaging and computed tomography showed stenosis of the distal bile duct and slight dilation of the upstream bile duct. Common bile duct stones and gallbladder stones were not detected. Malignant tumors in the bile duct biopsy were not discovered. The patient underwent subtotal stomach preserving pancreatoduodenectomy. The pathological diagnosis was chronic pancreatitis with amputation neuroma-like neurogenesis of the bile duct.

Lumbar epidural anaesthesia is a commonly used technique for analgesia during labour. One of the rare complications of this technique is pneumocephalus.

The enantiomers of many chiral drugs not only exhibit different pharmacological effects in regard to targets that dictate therapeutic and toxic effects, but are also handled differently in the body due to pharmacokinetic effects. We investigated the pharmacokinetics of the enantiomers of N-acetyl-leucine after administration of the racemate (N-acetyl-DL-leucine) or purified, pharmacologically active L-enantiomer (N-acetyl-L-leucine). The results suggest that during chronic administration of the racemate, the D-enantiomer would accumulate, which could have negative effects. Compounds were administered orally to mice. Plasma and tissue samples were collected at predetermined time points (0.25 to 8 h), quantified with liquid chromatography/mass spectrometry, and pharmacokinetic constants were calculated using a noncompartmental model. When administered as the racemate, both the maximum plasma concentration (Cmax) and the area under the plasma drug concentration over time curve (AUC) were much greater for the D-enantiomer relative to the L-enantiomer. When administered as the L-enantiomer, the dose proportionality was greater than unity compared to the racemate, suggesting saturable processes affecting uptake and/or metabolism. Elimination (ke and T1/2) was similar for both enantiomers. These results are most readily explained by inhibition of uptake at an intestinal carrier of the L-enantiomer by the D-enantiomer, and by first-pass metabolism of the L-, but not D-enantiomer, likely by deacetylation. In brain and muscle, N-acetyl-L-leucine levels were lower than N-acetyl-D-leucine, consistent with rapid conversion into L-leucine and utilization by normal leucine metabolism. In summary, the enantiomers of N-acetyl-leucine exhibit large, unexpected differences in pharmacokinetics due to both unique handling and/or inhibition of uptake and metabolism of the L-enantiomer by the D-enantiomer. Taken together, these results have clinical implications supporting the use of N-acetyl-L-leucine instead of the racemate or N-acetyl-D-leucine, and support the research and development of only N-acetyl-L-leucine.

Platelet-rich plasma (PRP) is an autologous blood product with platelets above circulating levels and releases several growth factors after activation. PRP may help to decrease joint inflammation by modulating synovial cell proliferation and differentiation and inhibition of catabolic pathways in various articular conditions. Though PRP has shown good efficacy in osteoarthritis and other musculoskeletal conditions such as synovitis, epicondylitis, skeletal muscle injuries, and tendinopathy, there is limited experience for the use of PRP in patients with rheumatoid arthritis. Precise mechanisms of action of PRP are not known. We present clinical experience for treatment with PRP (2-4 ml) in four patients with rheumatoid arthritis who had inadequate response and persistent pain and inflammation with intra-articular steroids. Irrespective of past and ongoing treatments and duration of disease, all patients showed improvement in the visual analog scale and disease activity score of 28 joints at 4 and 8 weeks after injection. There was an improvement in joint inflammation on ultrasound imaging in some patients. These effects were sustained for up to 1 year. No adverse effects were reported in any patient. PRP may be a safe and useful therapy in patients with rheumatoid arthritis who fail to respond to one or more established treatment options.

We read with interest the extended essay published from Riisfeldt and are encouraged by an empirical ethics article which attempts to ground theory and its claims in the real world. However, such attempts also have real-world consequences. We are concerned to read the paper's conclusion that clinical evidence weakens the distinction between euthanasia and normal palliative care prescribing. This is important. Globally, the most significant barrier to adequate symptom control in people with life-limiting illness is poor access to opioid analgesia. Opiophobia makes clinicians reluctant to prescribe and their patients reluctant to take opioids that might provide significant improvements in quality of life. We argue that the evidence base for the safety of opioid prescribing is broader than that presented, restricting the search to palliative care literature produces significant bias as safety experience and literature for opioids and sedatives exists in many fields. This is not acknowledged in the synthesis presented. By considering additional evidence, we reject the need for agnosticism and reaffirm that palliative opioid prescribing is safe. Second, palliative sedation in a clinical context is a poorly defined concept covering multiple interventions and treatment intentions. We detail these and show that continuous deep palliative sedation (CDPS) is a specific practice that remains controversial globally and is not considered routine practice. Rejecting agnosticism towards opioids and excluding CDPS from the definition of routine care allows the rejection of Riisfeldt's headline conclusion. On these grounds, we reaffirm the important distinction between palliative care prescribing and euthanasia in practice.

Post dural puncture headache (PDPH) is the most common complication of diagnostic and therapeutic lumbar puncture (LP).

In this systematic review and meta-analysis of psoriatic arthritis (PsA) studies, we pooled data from existing literature to (1) estimate the prevalence of mental health disorders in PsA patients and (2) compare disease activity in PsA patients with and without these comorbidities.
