Efficacy of topical Citrullus colocynthis (bitter apple) extract oil in chemotherapy-induced peripheral neuropathy: A pilot double-blind randomized placebo-controlled clinical trial.

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common complications in patients with cancer. Citrullus colocynthis (bitter apple) has been used in traditional Persian medicine as an effective pain relief, especially for neuralgia. We designed a pilot clinical trial to evaluate the safety and efficacy of topical C. colocynthis oil in management of CIPN in breast cancer patients. Thirty-four cancer patients with CIPN were randomly enrolled in two arms of a randomized, double-blind, placebo-controlled clinical trial. The patients were treated by topical C. colocynthis oil or placebo, two times per day for 2 months. Functional Assessment of Cancer Therapy/Gynecologic Oncology Group (FACT/GOG)-Neurotoxicity (Ntx) score was set as the primary outcome measure. No significant improvement was observed in the total score of FACT/GOG-Ntx scale (2.40 ± 1.90 vs. 1.05 ± 1.36, p = .879) in drug and placebo groups, respectively. There was also no significant improvement in the mean scores of FACT/GOG-Ntx in the sensory, motor, hearing, and functional domains in the two study groups. According to the results of this preliminary study, topical C. colocynthis oil failed to improve the symptoms of CIPN compared with placebo.

Effects of Chicory and Fumitory on Hot Flashes Among Breast Cancer Survivors: A Randomized, Double-Blind Placebo-Controlled Trial.

Objectives: Hot flashes are unpleasant long-term complications of breast cancer. This study aimed to evaluate the effects of a traditional Persian medicine containing extracts of Cichorium intybus L. (chicory) and Fumaria parviflora L. (Fumitory) extract syrup (CFS) compared with placebo when used as intended. Design: Randomized, double-blind, placebo-controlled clinical trial. Setting/Location: The Oncology Ward of Shahid Modarres Hospital (Tehran, Iran). Subjects: Breast cancer survivors undergoing hormone deprivation therapy. Interventions: Patients were randomly allocated to receive 5 mL CFS or placebo syrup three times a day, for 4 weeks. Outcome measures: The co-primary outcomes were self-reported daily hot flashes frequency and severity scores assessed using self-reported daily dairies, including 1 week of baseline data. Results: Of the 148 patients screened, 137 were eligible, and 96 were randomly allocated to receive either CFS (n = 48) or placebo (n = 48). All participants who returned their dairies were compliant and analyzed as randomized in the a priori per-protocol analysis. After 4 weeks of treatment, both the mean daily hot flashes frequency and severity score had reduced by 57% in the CFS group and 10% in the placebo group. The overall weekly mean daily hot flashes frequency (effect size ηp2 0.221, p < 0.001, n = 66) and severity scores (effect size ηp2 0.160, p = 0.001, n = 66) were significantly lower in the CFS group compared with the placebo group (one-within one-between repeated-measures analysis of variance adjusted for baseline). CFS was well tolerated, with similar proportions of serious and nonserious adverse events occurring in both groups. Conclusions: This is the first study to report the effects of chicory or fumitory for the treatment of hot flashes. The findings provide preliminary evidence that CFS can improve hot flashes in breast cancer survivors undergoing hormone deprivation therapy. More research is warranted to confirm its effectiveness, safety, and mechanisms of action. Clinical Trial Registration: IRCT20210226050506N1.

Bioinformatics Analysis of Key Genes and Pathways for Medulloblastoma as a Therapeutic Target

Introduction: One of the major challenges in cancer treatment is the lack of specific and accurate treatment in cancer. Data analysis can help to understand the underlying molecular mechanism that leads to better treatment. Increasing availability and reliability of DNA microarray data leads to increase the use of these data in a variety of cancers. This study aimed at applying and evaluating microarray data analyzing, identification of important pathways and gene network for medulloblastoma patients to improve treatment approaches especially target therapy. Methods: In the current study, Microarray gene expression data (GSE50161) were extracted from Geo datasets and then analyzed by the affylmGUI package to predict and investigate upregulated and downregulated genes in medulloblastoma. Then, the important pathways were determined by using software and gene enrichment analyses. Pathways visualization and network analyses were performed by Cytoscape. Results: A total number of 249 differentially expressed genes (DEGs) were identified in medulloblastoma compared to normal samples. Cell cycle, p53, and FoxO signaling pathways were indicated in medulloblastoma, and CDK1, CCNB1, CDK2, and WEE1 were identified as some of the important genes in the medulloblastoma. Conclusion: Identification of critical and specific pathway in any disease, in our case medulloblastoma, can lead us to better clinical management and accurate treatment and target therapy.

Effect of eradication of Helicobacter pylori on platelet recovery in patients with chronic idiopathic thrombocytopenic purpura: a controlled trial.

Several recent studies have suggested that an association exists between Helicobacter pylori (HP) eradication and improvement in platelet count in a significant proportion of patients with idiopathic thrombocytopenic purpura (ITP). In this controlled study, we prospectively examined adult patients with chronic ITP for HP infection, and assessed the effect of HP eradication on platelet count. One hundred forty-two consecutive Iranian patients with chronic ITP were assessed. Those who met the criteria and had platelet counts >30 x 10(9)/L within the medication-free screening month were enrolled (n = 129; 66 females; mean age, 29.2 +/- 7.0 years). HP-positive patients received a 2-week course of triple HP eradication therapy (i.e., amoxicillin, clarithromycin, and omeprazole) and were followed for 48 weeks. An ITP response was defined as a platelet count of >100 x 10(9)/L 24 weeks after treatment, together with an increase in the platelet count >30 x 10(9)/L over the baseline value. HP infection was detected in 79 (61%) patients. HP-positive patients were significantly older than HP-negative subjects (P = 0.018). HP eradication was successful in 87% (62/71) of those who completed the eradication therapy. Whereas 48% (30/62) of HP-eradicated patients showed an ITP response, no HP-negative patient had an ITP response. The ITP response persisted for 48 weeks in 93% (28/30) of the responders. The ITP responders had a shorter disease duration than the nonresponders (P = 0.002). The management of mild-to-moderate chronic ITP in Iranian patients, especially those with a recent onset of disease, should include an investigation for and eradication of infection with HP.

Clinical significance of positive platelet immunofluorescence assay in adult immune thrombocytopenia.

Immune thrombocytopenia (ITP) is a relatively common hematologic disorder manifested by low platelet count due to immune-mediated platelet destruction and/or suppression of platelet production. This study aim was to evaluate characteristics and clinical presentation of adult patients with ITP and exploring the clinical value of platelet antibodies assay in proposed cases in Iranian population. In this prospective case series 46 adult patients with ITP and platelet count of <100 × 10(9)/L, referred to the Taleghani Medical Center, Tehran, Iran between 2007 and 2009 were evaluated. There were 26 females and 20 males (1.3:1) with mean age of 38.9 ± 19.7 years. The platelet autoantibodies were measured by means of indirect platelet suspension immunofluorescence test. According to our results, 7 patients (15.2 %) displayed a positive platelet antibody assay. There was a significant negative correlation between platelet count and antibody level (r = -0 0.59; p < 0.001). Additionally, a positive correlation between platelet count and patients' age (r = 0.302; p = 0.042) was detected. 20 patients (56.5 %) were symptomatic at presentation and the most common bleeding signs were petechia, purpura and epistaxis. Results indicated no significant correlation between increased platelet antibody level and bleeding manifestations except for hematuria (r = 0.435; p = 0.02) and epistaxis (r = 0.382; p = 0.015). Disclosure of platelet autoantibodies and the consequential thrombocytopenia associated to some extent but not completely with the propensity to bleed which necessitates more factors to be evaluated.

Medical oncology, history and its future in Iran.

Systemic therapy is one of the cornerstones of cancer treatment. In 1972, following representations by American Society of Clinical Oncology (ASCO), the American Board of Internal Medicine (ABIM) recognized medical oncology as a new subspecialty of internal medicine. Subspecialty of Hematology and Medical Oncology was emerged in Iran in 1983. In the past, modern medical treatments and education were started in Dar Al-fonun school and then in Tehran University; now six universities in Iran are training in Subspecialty of Hematology and Medical Oncology. There are also ten active hematopoietic stem cell transplantation centers, thirty-one provincial medical schools use their specialized services. Future goals for Hematology and Medical Oncology in Iran include expansion and reinforcement of multidisciplinary teams across the country, early detection and prevention of cancer, providing educational program and conducting cancer researches. To achieve these goals, it is necessary to establish Cancer Hospitals in each province that link together through a network.

Successful catheter-directed venous thrombolysis in an ankylosing spondylitis patient with phlegmasia cerulea dolens.

Ankylosing spondylitis (AS) is an inflammatory rheumatic disease. Phlegmasia cerulea dolens is a severe form of deep vein thrombosis characterized by swelling, pain, and bluish discoloration. Treatment delay may cause venous gangrene, tissue ischemia, limb loss or death. Here, we present an AS case who presented with phlegmasia cerulea dolens and treated by catheter-directed thrombolysis.

Age at diagnosis and breast cancer survival in iran.

Background. Tumour characteristics are the most important prognostic factors in breast cancer. Patient-related factors such as young age at diagnosis, obesity, and smoking behaviour may also modify disease outcome. Due to the absence of a unique definition for "young age breast cancer" and the resulting variation in disease management, findings on the association between young age and prognosis of breast cancer are controversial. Methods. This study included 1500 patients with a primary diagnosis of breast cancer in six Iranian hospitals from 5 provinces. We modelled the relative excess risk (RER) of breast cancer death to age at diagnosis and tumour characteristics. Results. Excess risks of death were observed for stage IV disease and poorly differentiated tumours: RER of 4.3 (95% CI: 1.05-17.65) and 3.4 (95% CI: 1.17-9.87), respectively. "Older" patients, particularly those aged 50 and over, presented more often with advanced and poorly differentiated tumours (P = 0.001). After adjustment for stage, histological grade, Her-2 expression, estrogen and progesterone receptors, and place of residency, breast cancer mortality was not significantly different across age groups. Conclusion. We conclude that there is no prognostic effect of age at diagnosis of breast cancer among breast cancer patients treated at cancer centres in different parts of Iran; young and relatively old women have similar risks of dying from breast cancer.
