0%) and neurogenic changes in 5 (5.7%). The clinical and pathologic diagnoses were compatible in 24 patients (63.2%). The diagnostic yield of muscle biopsy remains significant, especially in this age group. Mitochondrial disease is a major diagnostic challenge, and muscle biopsy helps to support the clinical diagnosis and guide further studies.
Polymorphous low-grade neuroepithelial tumor of the young (PLNTY) is a rare entity with a diffuse, infiltrative pattern, awaiting to be included in the WHO CNS tumor classification; it occurs in pediatric and young patients with seizures and harbors mutually exclusive BRAFV600E or FGFR mutations. Nonetheless, the presence of these mutations may not be obligatory for diagnosis. The conventional histology of these tumors resembles that of oligodendrogliomas. We aimed to discuss a PLNTY case in a young woman presenting with seizures due to a parietal brain tumor and to provide an analysis of the literature. Histopathologically the tumor was consistent of oligodendroglioma-like neoplastic cells showing almost diffuse CD34 and olig-2 staining, retained ATRX expression, p53-negativity, and a low Ki67 index with no necrosis or microvascular proliferation.

1p/19q statuswas analyzed with FISH;
and
mutations were analyzed with minisequence analysis. Translocations, mutations, and expression analyses were studied for 18, 19, and 21 genes via targeted new-generation deep RNA sequencing, respectively.

The tumor did not carry 1p/19q codeletion, was IDH wild-type, and had radiological features compatible with the diagnosis of PLNTY. The tumor did not show BRAF or FGFR alterations but had an EGFR c.2342A>G (p.Asn781Ser) mutation which was likely a non-driver mutation due to its low allele frequency of 4%.

PLNTYs are rare brain tumors, and their accurate diagnosis is important to avoid improper management. Their prognosis shall be stratified according to their mutations.

The pathogenic mechanisms of IgG4-RD are divided into two sections one focused on potential initiation mechanisms, particularly genetic, and the other on specific pathological pathways. For the specific pathological pathways, cellular immunity, particularly T-cell mediated immunity, has been implicated in the pathogenesis of IgG4-RD. Renal involvement may manifest as an intrinsic IgG4-related kidney disease (IgG4-RKD) or as a consequence of ureteric obstruction from retroperitoneal fibrosis. PF-562271 in vivo Intrinsic kidney disease is most commonly a tubulointerstitial nephritis, but may also present with a variety of glomerular lesions, in particular membranous nephropathy. The first-line treatment of IgG4-RKD is steroids. The long-term side effects of corticosteroids including diabetes, relapses, and resistance to corticosteroid therapy have prompted some experts to use immunosuppressive agents such as rituximab. However, the pathogenesis remains poorly understood. As any delay in treatment may result in irreversible renal failure, early diagnosis and appropriate therapy are very important. Randomized studies are needed to confirm the efficacy of immunosuppressants such as rituximab.
The relative efficacy and safety of tofacitinib and mavrilimumab were assessed in patients with rheumatoid arthritis (RA) presenting an inadequate response to disease-modifying antirheumatic drugs (DMARDs).

We performed a Bayesian network meta-analysis combining direct and indirect evidence from randomized controlled trials (RCTs) to examine the efficacy and safety of tofacitinib and mavrilimumab combined with DMARDs in patients with an inadequate response to DMARDs.

In total, 8 RCTs with 2,965 patients met inclusion criteria. 21 pairwise comparisons were performed, including 12 direct comparisons of 7 interventions. In patients with active RA and an inadequate DMARD response, mavrilimumab 150 mg+methotrexate (MTX) and mavrilimumab 100 mg+MTX were the most effective treatments. Compared with placebo+MTX, all tofacitinib and mavrilimumab doses, except mavrilimumab 50mg+MTX, achieved significant ACR20 responses. The ranking probability based on the surface under the cumulative ranking curve indicated that mavrilimumab 150 mg+MTX had the highest probability for best treatment outcome in terms of the ACR20 response rate, followed by mavrilimumab 100 mg+MTX, tofacitinib 10 mg+MTX, tofacitinib 5 mg+MTX, mavrilimumab 30 mg+MTX, mavrilimumab 50 mg+MTX, and placebo+MTX. No significant differences were noted in the incidence of serious adverse events (SAEs) after tofacitinib+MTX, mavrilimumab+MTX, or placebo+MTX.

In patients with RA showing inadequate DMARD response, mavrilimumab 150 mg+MTX and mavrilimumab 100 mg+MTX, followed by tofacitinib 10 mg+MTX and tofacitinib 5 mg+MTX, were the most efficacious interventions and were not associated with a significant risk of SAEs.

It has been widely used in the remission and maintenance treatment of IBD. Some patients may experience some degree of myelosuppression, but very few patients experience severe myelosuppression. Here, we report a 20-year-old male Asian patient with severe myelosuppression due to azathioprine treatment of IBD. In this case, the azathioprine-related genotyping test showed that homozygous wild-type TPMT*3 but a c.415C>T homozygous mutation was found in NUDT15. Our report strengthens the association between genetic polymorphisms of azathioprine-metabolizing enzymes and severe myelosuppression. Therefore, we recommend routine NUDT15 c.415C>T phenotype testing prior to long-term azathioprine treatment to avoid severe myelosuppression.
To assess the safety, tolerability, and effectiveness of the intravenous immunoglobulin (IVIG) Intratect 100 g/L in a prospective, large-scale non-interventional study (NIS) of patients with a wide range of antibody deficiencies as well as other indications for IVIG, risk factors, and frequency of pre-treatments.

Patients were enrolled at 53 practices and clinics in Germany. After recording of baseline information, each patient was treated according to need, as judged by the physician and guided by the SmPC. Relevant data were acquired from medical records, and the patients completed questionnaires to assess treatment satisfaction and quality of life (QoL).

At cut-off for this interim analysis, 488 patients were enrolled (planned 1,000). 47% were male, age 16-91 (median 61) years, with treatment durations up to 2,225 (median 282) days. Indications were primary (32%) and secondary (61%) immunodeficiencies, immune thrombocytopenia (4%), and others (3%). More than 92% of physicians recorded very good effectiveness and satisfaction. Patient satisfaction and QoL increased with time from baseline. Initially, 31% of the SID patients had inadequate IgG trough levels (<4 g/L), including patients with (37%) and without (63%) previous IVIG treatment. Despite a relatively low IVIG dose (median 0.2 g/kg), trough levels improved after 3 infusions, only 22% of patients had trough levels <4 g/L, with a plateau below 17% after 6 infusions. Adverse reactions were observed at a rate of 3% per infusion, whereas 0.08% accounted for serious reactions.

Effectiveness, safety, patient satisfaction, and QoL were good, confirming the positive benefit-risk profile of the IVIG.

FOLFOX is a standard chemotherapy regimen used to treat colorectal cancer. Adverse events associated with FOLFOX treatment include peripheral neuropathy and myelosuppression. This report discusses the case of a 64-year-old man with rectal cancer who developed hyperammonemia and impaired consciousness following initiation of mFOLFOX6 as a postoperative adjuvant therapy.

This case study reports on the clinical disease progression of the aforementioned patient.

Following preoperative chemoradiotherapy, the patient underwent low anterior resection for rectal cancer. mFOLFOX6 was then initiated as postoperative adjuvant therapy. During the 5
cycle of mFOLFOX6 treatment, the patient presented with impaired consciousness and upper extremity convulsions. Blood testing revealed marked hyperammonemia (349 µg/dL (normal range 12-66 µg/dL)). Imaging did not reveal any intracranial lesions that could cause impaired consciousness. The patient recovered within a day after rehydration and BCAA substitution.

Although impaired consciousness is a rare adverse reaction of FOLFOX, it has a major psychological impact on the patient and his/her family. Hyperammonemia should therefore be considered a potential cause of impaired consciousness during FOLFOX therapy and should be appropriately diagnosed and treated.

A 32-year-old woman suffered from chills, fatigue, and chest distress after receiving one 80-mg terconazole vaginal suppository for the treatment of uncomplicated VVC. Then, the symptom persisted for 10 hours until the residue of terconazole was removed, and the vagina was repeatedly washed with iodophor. In addition, white blood cell (WBC), neutrophil, C-reactive protein (CRP), and procalcitonin (PCT) were tested and showed marked increase when the patient visited our hospital again on the next day after the treatment with terconazole. Intriguingly, these parameters gradually decreased after a single dose of intravenous fluids (0.9% sodium chloride injection 500 mL and 10% glucose injection 500 mL) instead of the antibiotic therapy. On the third day, WBC and neutrophils returned to normal levels. Thus, according to the Naranjo adverse drug reaction probability scale, terconazole was the probable cause of the symptoms and the elevated WBC, neutrophil, CRP, and PCT. To date, this is the first report that chest distress, and at the same time, elevation of WBC, neutrophil, CRP, and PCT were caused by terconazole. This would be beneficial to avoid the overuse of antibiotics. Resolving the adverse drug reaction with drug removal and intravenous fluids would be beneficial to avoid the overuse of antibiotics.
