BACKGROUND: Polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes (POEMS) syndrome is a rare plasma cell (PC) neoplasm with associated paraneoplastic syndrome. According to the current diagnostic criteria, peripheral polyneuropathy and monoclonal PC proliferative disorder represent two mandatory criteria.
METHODS: We report a 54-year-old male with peripheral neuropathy of bilateral lower limbs, sclerotic bone lesions, elevated vascular endothelial growth factor (VEGF) levels, splenomegaly, extravascular volume overload, endocrinopathy, and skin hemangiomas. Of note, serum and urine protein electrophoresis (PEP) and immunofixation electrophoresis (IFE) of this patient indicated undetectable M-protein and the normal ratio of free light chains κ and λ (FLC-R (κ/λ)). No monoclonal PCs were found in bone marrow examinations or biopsy of diseased bones. However, his clinical manifestations matched most of the diagnostic criteria. After excluding other diseases that are easily confused with POEMS syndrome, the diagnosis of variant POEMS syndrome with undetectable M-protein was proposed. The patient obtained clinically significant improvement and elevated VEGF returned to normal after 6 months of treatment with lenalidomide plus dexamethasone.
CONCLUSIONS: Monoclonal PC dyscrasia (M-protein) while being a mandatory criterion for POEMS syndrome is undetectable in a considerable amount of patients that otherwise demonstrate typical symptoms. Here, we reported a case of variant POEMS syndrome with featured clinical manifestations, elevated VEGF levels, and good response to therapies targeting PCs but no evidence of M-protein. Therefore, negative results in M-protein and monoclonal PCs aren\'t enough to reject the diagnosis of POEMS syndrome. It is imperative to recognize the variant form of POEMS syndrome.

UNASSIGNED: Ixekizumab, an interleukin (IL)-17A inhibitor, exerts its therapeutic effects in psoriasis by inhibiting the interleukin (IL)-17 signaling pathway. Common adverse reactions to ixekizumab include injection site reactions and upper respiratory tract infections (URIs), while occurrences of inflammatory bowel disease (IBD) and multiple mucosal ulcers are infrequent. We present a case of a 51-year-old man who developed multiple mucosal ulcers after ixekizumab treatment.
UNASSIGNED: A 51-year-old man presented to our hospital with a 1-month history of pharyngalgia. The flexible laryngoscope displayed mild hyperemia in the pharyngeal mucosa and tonsils, redness and swelling of the epiglottis, as well as multiple ulcers in the oral cavity, uvula, and epiglottis. These ulcers did not improve with conventional treatment.
UNASSIGNED: Upon evaluation, the ulcers were an immune-related adverse event induced by ixekizumab. Consequently, a decision was made to discontinue the drug and initiate a therapeutic regimen including corticosteroids and thalidomide. Eventually, the patient\'s symptoms abated.
UNASSIGNED: Biologics are now becoming increasingly popular in psoriasis. It is vital for clinicians to be aware of this potential adverse event and to identify and intervene early to alleviate patients\' suffering.

Here we reported a case of a 52-year-old male with a 13-year history of Crohn\'s disease who developed disseminated tuberculosis after 2 injections of infliximab. The patient was admitted with a chief complaint of fever with headache of 1 month\'s duration. Mycobacterium tuberculosis DNA was found positive in cerebrospinal fluid and lavage fluid by lumbar puncture and bronchoscopy. He was diagnosed with tuberculous meningitis, pulmonary tuberculosis, tracheobronchial tuberculosis and lymph node tuberculosis. After treatment with anti-tuberculosis and glucocorticoids, the symptoms did not improve, the lesions progressed, and granulomas were formed in the tracheobronchial lumen. These were considered to be contradictory reactions and thalidomide was given together with glucocorticoids. The patient\'s clinical condition has improved significantly. Treatment was successfully completed after 18 months with 1 HREZLfxLzd/8 HEZCsLzd/1 HEZCs/8 HZCs.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and highly aggressive hematological malignancy, there is no standard treatment and the prognosis is very poor. Affiliated Zhongshan Hospital of Dalian University report a case of 85-year-old BPDCN male patient treated with DVT regimen (decitabine combined with Venetoclax and thalidomide) and achieved complete remission. The patient with skin nodules and the pathology diagnosed BPDCN, the next generation sequencing of skin nodules showed mutations of IDH2 and ASXL1. DVT (decitabine combined with Venetoclax and thalidomide) has significant efficacy with rapid and deep remission for BPDCN, and the adverse effects is less, especially suitable for elderly patients who cannot tolerate intense chemotherapy.

OBJECTIVE: The purpose of this study is to investigate the effectiveness and safety of oral and injectable systemic treatments, such as methotrexate, azathioprine, cyclosporine, tofacitinib, baricitinib, corticosteroids, statins, zinc, apremilast, etc., for treating vitiligo lesions.
METHODS: Databases including PubMed, Scopus, and Web of Science were meticulously searched for studies spanning from 2010 to August 2023, focusing on systemic oral and injectable therapies for vitiligo, using comprehensive keywords and search syntaxes tailored to each database. Key data extracted included study design, treatment efficacy, patient outcomes, patient satisfaction, and safety profiles.
RESULTS: In a total of 42 included studies, oral mini-pulse corticosteroid therapy (OMP) was the subject of six studies (14.2%). Minocycline was the focus of five studies (11.9%), while methotrexate, apremilast, and tofacitinib each were examined in four studies (9.5%). Antioxidants and Afamelanotide were the subjects of three studies each (7.1%). Cyclosporine, simvastatin, oral zinc, oral corticosteroids (excluding OMP) and injections, and baricitinib were each explored in two studies (4.8%). Azathioprine, mycophenolate mofetil, and Alefacept were the subjects of one study each (2.4%).
CONCLUSIONS: Systemic treatments for vitiligo have been successful in controlling lesions without notable side effects. OMP, Methotrexate, Azathioprine, Cyclosporine, Mycophenolate mofetil, Simvastatin, Apremilast, Minocycline, Afamelanotide, Tofacitinib, Baricitinib, Antioxidants, and oral/injectable corticosteroids are effective treatment methods. However, oral zinc and alefacept did not show effectiveness.

BACKGROUND: Capsaicin is a highly selective agonist of the transient receptor potential vanilloid 1. The adhesive capsaicin patch provides a high capsaicin concentration (8%) directly in the painful area - its efficacy in benign peripheral neuropathic pain (diabetic neuropathy or postherpetic neuralgia) has recently been described in the literature. However, there is scant evidence of its efficacy in chemotherapy-induced peripheral neuropathy (CIPN). This is a concern for patients with multiple myeloma, who suffer from peripheral neuropathic pain induced by first-line treatments (bortezomib or thalidomide).
OBJECTIVE: To describe improved control of CIPN in patients with multiple myeloma using adhesive capsaicin 8% patch.
METHODS: We opted for a retrospective observational case series. Between October 2017 and October 2020, we collected clinical data from adult multiple myeloma patients affected by CIPN who were administered the capsaicin 8% patch in our palliative care outpatient clinic. We compiled Numerical Pain Rating Scale (NPRS) scores, patients\' medication needs and performance status before and after patch application.
RESULTS: Two women and five men with an average age of 62.85 years received bortezomib. Two patients (28.57% of the sample) also received thalidomide. The average NPRS score before patch application was 6.42/10. Five of the seven patients (71.42%) received a mean daily oral morphine dose of 52.85 mg/day, five (71.42%) received gabapentinoids and one (14.28%) received antidepressants. The average NPRS score decreased to 4/10 seven days after patch application, while the mean daily oral morphine dose remained stable. Performance status improved slightly in two patients (28.57%) and remained stable in the rest. One patient (14.28%) required an extra analgesic dose during patch application.
CONCLUSIONS: Capsaicin 8% patch application appears to reduce pain intensity in patients with multiple myeloma suffering from CIPN.

A 35-year-old male patient with lepromatous leprosy came to the emergency room (ER) due to breathlessness and chest pain. The patient was diagnosed with pulmonary tuberculosis (TB) after a bronchoscopy and started on antitubercular therapy. However, the patient continued to experience tachycardia and desaturation, and on further evaluation, Computed tomography pulmonary angiography revealed an embolus in the right descending pulmonary artery. The patient was found to have an elevated d-dimer. Further investigation revealed that the cause of the pulmonary thromboembolism (PTE) was the thalidomide medication that the patient was taking for type 2 leprosy reaction. The medication was stopped, and the patient was treated with low-molecular-weight heparin and discharged with apixaban for six months. The patient\'s condition improved on follow-up. This case is unique due to the rare combination of pulmonary TB, leprosy, and pulmonary embolism brought on by thalidomide administration. Physicians should be aware of the possibility of co-infection of TB and leprosy and the need to rule out thromboembolism when patients are on thalidomide.

Tropical diseases prevalent in leprosy-endemic areas may alter the immunological patient response and also complicate the presentation of leprosy reactional episodes. The introduction of anti-malarial drugs in our case produced a subsidence of reaction. With dwindling manpower skilled in leprosy, the reactional episodes are very often treated with non-steroidal anti-inflammatory drugs, steroids and thalidomide, neglecting the possibility of other co-existing infections, tropical or other. Our case emphasises the importance of history, examination and balanced investigation in the context of tropical diseases in endemic areas before injudicious intervention.
