BACKGROUND: Non-tubal ectopic pregnancies account for < 10% of all ectopic pregnancies. Due to its rarity and wide variation in clinical practice, there is no guideline or consensus for its management. We reported our 20-year experience in the management of non-tubal ectopic pregnancies in a tertiary hospital.
METHODS: This is a retrospective review of all women admitted for non-tubal ectopic pregnancies from January 2003 to December 2022 in a tertiary hospital. Women with non-tubal ectopic pregnancies diagnosed by ultrasound or operation were included for analysis.
RESULTS: Within the study period, 180 women were diagnosed to have non-tubal ectopic pregnancies at a mean gestation of 6.8 weeks. 16.7% (30/180) were conceived via assisted reproduction. Medical treatment was the first-line management option for 81 women, of which 75 (92.1%) women received intralesional methotrexate administered under transvaginal ultrasound guidance. The success rate of intralesional methotrexate ranges from 76.5% to 92.3%. Intralesional methotrexate was successful even in cases with a positive fetal pulsation or with high human chorionic gonadotrophin levels up to 252605U/L. Twenty seven women were managed expectantly and 40 underwent surgery. Nine (11.1%), two (6.1%), and one (2.3%) women required surgery due to massive or recurrent bleeding following medical, expectant, or surgical treatment. Hysterotomy and uterine artery embolization were necessary to control bleeding in one Caesarean scar and one cervical pregnancy.
CONCLUSIONS: Intralesional methotrexate is more effective than systemic methotrexate and should be considered as first line medical treatment for non-tubal ectopic pregnancies. It has a high success rate in the management of unruptured non-tubal ectopic pregnancies even in the presence of fetal pulsations or high human chorionic gonadotrophin levels, but patients may require a prolonged period of monitoring. Close surveillance and readily available surgery were required due to the risk of heavy post-procedural intra-abdominal bleeding.

Analyze the relationship between genetic variations in the MTHFR gene at SNPs (rs1801131 and rs1801133) and the therapy outcomes for Iraqi patients with rheumatoid arthritis (RA). The study was conducted on a cohort of 95 RA Iraqi patients. Based on their treatment response, the cohort was divided into two groups: the responder (47 patients) and the nonresponder (48 patients), identified after at least three months of methotrexate (MTX) treatment. A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was employed to analyze the MTHFR variations, specifically at rs1801133 and rs1801131. Overall, rs1801131 followed both codominant and dominate models, in which in the codominant model, GG [OR (95% CI) 0.11 (0.022-0.553)] and TG [OR (95% CI) 0.106 (0.021-0.528)] predict responders compared to the TT genotype; meanwhile, for the dominate model, the presence of both GG and TG genotypes [OR (95% CI) 0.108 (0.023-0.507)] together predict responders compared to the TT genotype. The Ars1801133Grs1801131 haplotype was significantly associated with responders [OR (95% CI): 0.388 (0.208-0.723)], while the Grs1801133Trs1801131 haplotype was associated marginally with nonresponders [OR (95% CI) 1.980 (0.965-4.064)]. In the final multivariate analysis, GG/TGrs1801131 genotypes were independently related to responders after adjustment for patients, disease, and treatment characteristics, while TTrs1801131 genotypes were associated with nonresponders. The Iraqi RA patients showed genetic polymorphism in MTHFR gene rs1801131 with T carrier allele associated with nonresponders to MTX therapy. The rs1801131 followed both codominant and dominant models. The G-carried allele for rs1801131 showed an independent association with responder to MTX therapy after adjustment for patients, disease, and treatment characteristics.

Colon cancer (CC) is one of the most prevalent cancers in the world, and chemotherapy is widely applied to combat it. However, chemotherapy drugs have severe side effects and emergence of multi drug resistance (MDR) is common. This bottleneck can be overcome by niosome nanocarriers that minimize drug dose/toxicity meanwhile allow co-loading of incompatible drugs for combination therapy. In this research, silibinin (Sil) as a hydrophobic drug was loaded into the lipophilic part, and methotrexate (MTX) into the hydrophilic part of niosome by the thin film hydration (TFH) method to form Nio@MS NPs for CT26 colon cancer therapy in vitro. Our results indicated synthesis of ideal niosome nanoparticles (NPs) with spherical morphology, size of ~100 nm, and a zeta potential of -10 mV. The IC50 value for Nio@MS was determined ~2.6 µg/mL, which was significantly lower than MTX-Sil (~6.86 µg/mL), Sil (18.46 µg/mL), and MTX (9.8 µg/mL). Further, Nio@MS significantly reduced cell adhesion density, promoted apoptosis and increased gene expression level of caspase 3 and BAX while promoted significant downregulation of BCL2. In conclusion, the design and application of niosome to co-administer Sil and MTX can increase the drugs cytotoxicity, reduce their dose and improve anti-cancer potential by combating MDR. .

Dercum\'s disease (DD) is a rare and poorly understood disease characterized by obesity and painful lipomas throughout the body. Although the entity is well described in the literature, its etiology, prevalence, and treatment remain unclear. Currently, treatment is focused on pain management. We describe a case of a patient with DD who showed improvement with infliximab and methotrexate.

A cesarean scar pregnancy (CSP) is a rare form of ectopic pregnancy. Proper diagnosis and management of CSP are incredibly important secondary to the risk of uterine rupture and life-threatening hemorrhage. Various medical and surgical management have been described previously. This report looks at two cases of CSP diagnosed at an urban hospital in Atlanta, Georgia. The first woman was 30 years old with a history of five prior CS. She was referred from an abortion clinic for CSP at 6 weeks 2 days gestation. She did not desire future fertility and opted for a hysterectomy. The second woman was 38 years old with a history of three prior CS presenting with vaginal bleeding and abdominal pain and found to have a CSP with a gestation sac measuring 5 weeks 1 day. Given the patient\'s desires for future fertility, she was treated with a two-dose regimen of systemic intramuscular methotrexate (MTX) at 1 mg/kg with successful resolution of CSP and subsequent intrauterine pregnancy. Due to the high risk of uterine rupture and hemorrhage with CSP, it is important to have a high index of suspicion for diagnosis. Due to the rarity of CSP, and thus difficulty creating quality prospective trials, there is no consensus on the best management yet. Although conservative treatment carries high failure risk, shared decision-making incorporating future fertility desires should be considered when determining management of CSP, and when surgical management is considered a minimally invasive approach should be the standard of care in surgical management.

This study presents a rare case of an Epstein-Barr virus-positive mucocutaneous ulcer (EBVMCU) co-existing with medication-related osteonecrosis of the jaw (MRONJ) in the mandible of a 54-year-old Japanese man who complained of painful swelling of the left mandibular gingiva over the past three months. The patient had a history of methotrexate (MTX) and bisphosphonates (BPs) use. Intraoral examination revealed a 35 mm large ulcerative lesion with marginal gingival swelling and bone exposure on the left side of the mandible. A biopsy was performed, confirming the diagnosis of EBVMCU with MRONJ. Due to the enlargement of the bone exposure, marginal resection of the mandible was performed under general anesthesia as a treatment for residual MRONJ. At the two-year follow-up, no evidence of recurrence was observed.

BACKGROUND: Choriocarcinoma is a highly malignant pregnancy-related trophoblastic neoplasm, characterized by early metastasis to the lungs. Therefore, patients may manifest nongynecological symptoms owing to distant metastases. The incidence of choriocarcinoma after a term pregnancy is really rare (1/160,000 pregnancies).
METHODS: We report a case of a 20-year-old Iranian woman, gravida 2 para 1 live 1 abortion 1, who was referred to our gynecology department with sudden onset dyspnea and pain in the left hemithorax the day after her labor. The index pregnancy was without any complications. After the initial workup, the elevation of β-human chorionic gonadotropin (HCG) levels (> 1,000,000) along with the identification of clinical (vaginal lesions) and radiological evidence of distant metastases (bilateral pulmonary nodes) directed us toward pulmonary metastatic choriocarcinoma diagnosis. After the oncology consult, the etoposide, methotrexate, actinomycin D, cyclophosphamide, and vincristine chemotherapy regimen was started for the patient. She responded well to the treatment and is currently continuing her chemotherapy process.
CONCLUSIONS: The prognosis of choriocarcinoma is very good if the treatment is started on time. We suggest that clinicians should consider gestational trophoblastic neoplasia in their differential diagnosis of the post-natal period complications, especially after a term and nonmolar pregnancy.

Cholesterol-rich nanoemulsion (LDE) can carry chemotherapeutic agents in the circulation and can concentrate those agents in the neoplastic and inflammatory tissues. This method improves the biodistribution of the drug and reduces toxicity. However, the structural stability of LDE particles, without or with associated drugs, has not been extensively investigated. The aim of the present study is to investigate the structural stability of LDE and LDE associated to paclitaxel, etoposide or methotrexate in aqueous solution over time by small-angle X-ray scattering (SAXS and Ultra SAXS) and dynamic light scattering (DLS). The results show that LDE and LDE associated with those chemotherapeutic agents had reproducible and stable particle diameter, physical structure, and aggregation behavior over 3-month observation period. As estimated from both DLS and Ultra-SAXS methods, performed at pre-established intervals, the average particle diameter of LDE alone was approx. 32 nm, of LDE-paclitaxel was 31 nm, of LDE-methotrexate was 35 nm and of LDE-etoposide was 36 nm. Ultra-SAXS analysis showed that LDE nanoparticles were quasi-spherical, and SAXS showed that drug molecules inside the particles showed a layered-like organization. Formulations of LDE with associated PTX, ETO or MTX were successfully tested in animal experiments and in patients with cancer or with cardiovascular disease, showing markedly low toxicity, good tolerability and possible superior pharmacological action. Our results may be useful for ensuing clinical trials of this novel Nanomedicine tool, by strengthening the knowledge of the structural aspects of those LDE formulations.

Psoriasis might bring about an increased risk of liver diseases like nonalcoholic fatty liver disease and fibrosis. The impact of methotrexate on liver function is still a cause for concern, because of the studies suggesting an increased risk of liver damage and others finding no association. The focus of this study was the liver functions in psoriatic patients investigating the impact of long-term use of methotrexate on liver in psoriasis. A retrospective investigation including 140 patients with psoriasis receiving methotrexate treatment for at least 6 months and a control group consisted of 105 healthy ones was conducted. Liver function tests (AST, ALT, PLT) were assessed, and the association of baseline PASI with FIB-4 and APRI values was investigated. Additionally, FIB-4 and APRI values at baseline, 3rd, and 6th months of methotrexate treatment for psoriasis were compared. Compared with the controls, psoriatic patients exhibited significantly higher FIB-4 scores (p = 0.004). A moderate and significant correlation was observed between baseline PASI score and baseline FIB-4 score in psoriatic patients (p < 0.001, rho = 0.626). Long-term methotrexate use had no effect on APRI or FIB-4 (p = 0.104 and p = 0.475, respectively). Psoriatic patients face an elevated risk of liver fibrosis. Long-term methotrexate use does not adversely affect liver function in psoriatic patients. Noninvasive tools like APRI and FIB-4 scores can be employed to evaluate the risk of liver disease in these patients.
