Scleroderma Renal Crisis With Thrombotic Microangiopathy Treated With Eculizumab.

We herein report the unusual case of a 52-year-old female with systemic scleroderma who was admitted to the emergency department (ED) with renal dysfunction and hypertension. Following a decline in hemoglobin (Hb) and platelet (Plt) count, the diagnosis of scleroderma renal crisis (SRC) with associated microangiopathic hemolytic anemia was made. Renal replacement therapy using hemodialysis was required. Systemic scleroderma is a chronic autoimmune multisystem vasculopathy affecting several vessel beds, including distal extremities, kidneys, and lungs. Microangiopathic hemolytic anemia occurs in almost half of patients who develop scleroderma renal crisis. This association is thought to be related to the activation of the complement system via the classical pathway. Based on that, we administered a C5 blocker (eculizumab) to our patient and reported an unprecedented positive outcome.

The Impact of IDH1 Mutation and MGMT Promoter Methylation on Recurrence-Free Interval in Glioblastoma Patients Treated With Radiotherapy and Chemotherapeutic Agents.

The aim of this study is to investigate the relationship between isocitrate dehydrogenase-1 (IDH1) mutation and O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation with recurrence-free interval in glioblastoma patients treated with chemoradiotherapies. Clinical data were collected from 82 patients with totally resected glioblastoma and treated with adjuvant therapies from 2014 to 2019. IDH1 mutation was assessed by immunohistochemistry and MGMT promoter methylation was assessed by different sequencing methods. IDH1 mutation was present in 32 cases and 50 cases were IDH1 wildtype; 54 and 28 patients had unmethylated and methylated MGMT promoter, respectively, Of the 82 patients, 62 patients received chemoradiotherapy while 20 patients only received radiation. Approximately, 61% of patients had a tumor recurrence after 1 year, and 39% showed a recurrence before 1 year of treatment. There was no significant relationship between IDH1 mutation and MGMT promoter methylation (p-value = 0.972). Patients with IDH1 mutation and their age <50 years showed a significant difference in recurrence-free interval (p-value = 0.014). Difference in recurrence-free interval was also statistically observed in patients with unmethylated MGMT promoter and treated with chemoradiotherapies (p-value = 0.031), by which they showed a late tumor recurrence (p-value = 0.016). This revealed that IDH1 mutation and MGMT methylation are independent prognostic factors in glioblastoma. Although IDH1-mutant glioblastomas showed late tumor recurrence in patients less than 50 years old, the type of treatment modalities may not show additional beneficial outcome. Patients with unmethylated MGMT and IDH1 mutation, treated with different chemoradiotherapies, showed a late tumor recurrence.

Prognostic value of TP53 expression and MGMT methylation in glioblastoma patients treated with temozolomide combined with other chemotherapies.

OBJECTIVE: To assess the recurrence interval and predictive significance of TP53 expression and O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation in glioblastomas treated with radiotherapy and combined chemotherapies, including temozolomide, lomustine, procarbazine and bevacizumab. METHOD: We reviewed the clinical outcomes of 52 totally resected glioblastoma patients, who received conventional radiotherapy and temozolomide with other chemotherapeutic agents. Correlation of TP53 expression and MGMT promotor methylation with recurrence interval was analyzed using Kaplan Meier estimates. RESULTS: No significant association was found between MGMT promotor methylation and TP53 expression in glioblastomas (P-value = 0.158). Patients with non-methylated MGMT who received temozolomide chemotherapy with other chemotherapeutic agents showed significantly later recurrence (P-value = 0.007) compared with patients with non-methylated MGMT who received temozolomide alone. No significant difference was found in recurrence interval among glioblastoma patients with methylated MGMT who received temozolomide alone or with other chemotherapies (P-value = 0.667). Moreover, patients with non-TP53-expressing tumors who received temozolomide with other chemotherapies had significantly later recurrence (P-value = 0.04) compared with patients who received temozolomide alone. CONCLUSION: Totally resected glioblastoma patients, with non-methylated MGMT or non-TP53-expressing tumors treated with radiotherapy and combined chemotherapies had a reduced chance of tumor recurrence and a more favorable outcome. Furthermore, both MGMT and TP53 are independent prognostic factors for glioblastoma.

Concomitant presentation of IgG4-negative idiopathic retroperitoneal fibrosis and Addison's disease.

We describe a patient who was admitted to our medical centre with acute renal failure, hyponatraemia and hyperkalaemia. CT of the abdomen and pelvis showed a retroperitoneal mass with bilateral ureteral obstruction. Biopsy revealed fibrosis with inflammatory infiltrate, but rare IgG4-positive plasma cells. After placement of bilateral pigtail nephrostomy catheters, renal failure improved but metabolic derangements remained. Morning serum cortisol level was equivocal, but with blunted response on cosyntropin stimulation testing indicating adrenal insufficiency. Serology for 21-hydroxylase antibodies was strongly positive, supporting the diagnosis of Addison's disease. In addition to nephrostomy catheters for obstructive uropathy, idiopathic retroperitoneal fibrosis was treated with mycophenolate mofetil. Physiological doses of hydrocortisone and fludrocortisone for Addison's disease were also initiated. The patient continues to be monitored for regression of the mass. Based on review of the literature, this is the first reported case of IgG4-negative idiopathic retroperitoneal fibrosis presenting with autoimmune primary adrenal insufficiency.

A 12-week, randomized, double-blind, placebo-controlled, sequential parallel comparison trial of ziprasidone as monotherapy for major depressive disorder.

OBJECTIVE: To study ziprasidone monotherapy for major depressive disorder, defined according to the DSM-IV. METHOD: One hundred twenty outpatients were enrolled between June 2008 and September 2010 in a 12-week study that was divided into two 6-week periods according to the sequential parallel comparison design. Patients were randomized in a 2:3:3 fashion to receive ziprasidone for 12 weeks, placebo for 6 weeks followed by ziprasidone for 6 weeks, or placebo for 12 weeks. The main outcome measure was the 17-item Hamilton Depression Rating Scale (HDRS-17), with the Quick Inventory of Depressive Symptomatology, Self-Rated (QIDS-SR), and Clinical Global Impressions-Severity of Illness scale (CGI-S) serving as the study secondary measures. RESULTS: One hundred twenty patients (53 women [44.1%]) were randomized to treatment. The mean (SD) age of these patients was 43.7 (11.0) years. Mean (SD) baseline HDRS-17, CGI-S, and QIDS-SR scores were 19.9 (5.0), 4.3 (0.6), and 15.6 (3.0), respectively. There was no statistically significant difference in reduction of depressive symptoms, response rates, or remission rates between ziprasidone- or placebo-treated patients. This was true for both the study primary as well as secondary outcome scales. CONCLUSIONS: In conclusion, treatment with ziprasidone monotherapy was not associated with any statistically significant advantage in efficacy over placebo. Although studies involving larger sample size would be required to have adequate statistical power to detect treatment differences smaller than 2.5 points on the HDRS-17, such differences would be of questionable clinical relevance. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT00555997.

Comparison of superficial mycosis treatment using Butenafine and Bifonazole nitrate clinical efficacy.

Superficial fungal infections are commonly encountered by the physician. And the continuously changing epidemiology of invasive fungal infections results in the need for an expanded armamentarium of antifungal therapies. This study was designed to evaluate the safety and efficacy of Butenafine (BTF) versus Bifonazole (BFZ) in the treatment of superficial mycosis in a randomized, double-blind, parallel-group trial. Of 96 patients, 48 applied (BTF) cream and 48 applied (BFZ) cream for 2 weeks to tinea versicolor, corporis and cruris treat, while tinea of feet & hands was treated for 4 weeks duration. Efficacy was assessed after the end of treatment and 2 weeks later. At the end of therapy, we find somewhat more patients using (BTF) than using (BFZ) had a mycologic cure ((BTF), 87.5%; (BFZ) 83.3%) and effective clinical response ((BTF), 91.7%; (BFZ), 83.3%). (BTF) provides rapid and persistent antifungal activity and symptom relief in patients with superficial mycosis during treatment. And patients continued to improve for at least 2 weeks after treatment. The Rates of mycologic cure and effective treatment with (BTF) were higher than with (BFZ) at cessation of treatment and 2 weeks later. However, no significant difference found between the two drugs (p> 0.05).

Demonstration of the efficacy and safety of a novel substance P (NK1) receptor antagonist in major depression.

The efficacy and safety of a selective NK(1) antagonist, L-759274, was investigated in outpatients with diagnosis of major depressive disorder with melancholic features, following evidence obtained with the novel compound aprepitant that Substance P (NK(1)) antagonists may provide a unique mechanism of antidepressant activity. A randomized, double-blind placebo-controlled study was carried out. Patients, male or female, aged 18-60, scoring >/=25 points on total of first 17 items of 21-item Hamilton Depression Scale (HAMD), and scoring >/=4 (moderately ill) on Clinical Global Impressions-Severity Scale were randomized to oral L-759274 40 mg daily (n=66) or placebo (n=62) for 6 weeks. For patients receiving L-759274, improvement (mean decrease from baseline) in HAMD-17 total score was 10.7 points, compared with a mean 7.8 point improvement in patients receiving placebo (p<0.009). Mean scores for item 1 of HAMD-17 (depressed mood) also improved to a greater extent in the active group compared with the placebo group (0.3 points, p<0.058). Compared with placebo, mean scores on Clinical Global Impressions-Improvement Scale improved significantly by the end of the trial (p=0.009). L-759274 was generally safe and well-tolerated. The incidence of sexual side effects was on par with that observed in patients receiving placebo, and the incidences of gastrointestinal effects were low. Antidepressant actions have now been observed with two different highly selective NK(1) antagonists (aprepitant and L-759274). NK(1) antagonism is a replicated and generally well-tolerated antidepressant mechanism.

Extradural cord compression due to metastatic oligodendroglioma.

Extraneural metastases from primary intracranial tumours are extremely rare. We present a case of metastatic oligodendroglioma causing extradural spinal cord compression at the level of the sixth thoracic vertebrae resulting in paraplegia. We discuss the routes of tumour dissemination and possible reasons for the rarity of cases of metastatic oligodendroglioma.
