Effect of Melissa officinalis on Chemotherapy-Induced Peripheral Neuropathy in Cancer Patients: A Randomized Trial.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a significant cancer treatment side effect that can influence both quality of life and treatment course. Melissa Officinalis (MO), due to its high content of flavonoids, has antioxidant, anti-inflammatory, and neuroprotective properties.  Materials and Methods: The cancer patients diagnosed with CIPN attended a referral center in Sari (Iran). The hydroalcoholic extract of MO leaves was extracted by the maceration method. The control group received a placebo along with gabapentin as the standard treatment, and the intervention group received 500 mg Melissa officinalis 2 times daily for 3 months plus gabapentin. Patients were evaluated at the baseline and 3 months later, according to Common Terminology Criteria for Adverse Effects (CTCAE) and EORTC QLQ-C30 (Integrated System for Quality of Life Assessment).  Results: A total of 40 patients were considered as group D (intervention group), and 35 patients completed the study. Out of 40 subjects in the placebo group (P), 3 patients could not tolerate the drug due to gastrointestinal disturbances. The final values of CTCAE showed a statistically significant difference (p=0.010). Indicators related to the quality of life in both groups showed a significant improvement. In the intervention group, the pain perception and diarrhea experience were significantly reduced. Conclusion: Quality of life indicators were improved by prescribing gabapentin with and without Melissa officinalis. The addition of Melissa officinalis to the chemotherapy regimen may improve diarrhea and pain perception.

Outcome of epilepsy surgery in lesional epilepsy: Experiences from a developing country.

BACKGROUND: Our aim was to report the postoperative seizure outcome and associated factors in patients with lesional epilepsy, in a low-income setting. METHODS: This longitudinal prospective study included patients who underwent epilepsy surgery at Kashani Comprehensive Epilepsy Center between 2014 and 2019. Post-surgical outcomes were reported according to the Engel score, and patients were classified into two groups of seizure free (SF) and not-seizure free (NSF). RESULTS: A total of 148 adult patients, with a mean age of 30.45 ±â€¯9.23 years were included. The SF outcome was reported in 86.5% of patients and antiepileptic drugs (AEDs) were reduced or discontinued in 45.9%. The mean follow-up duration was 26.7 ±â€¯14.9 months. Temporal lobe lesions (76.3%) and mesial temporal sclerosis (MTS) (56.7%) were the most frequent etiologies. Temporal lesion (Incidence relative risk (IRR): 1.76, 95% CI [1.08-2.87], p = 0.023), prior history of CNS infection (IRR:1.18, 95% CI [1.03-1.35], p = 0.019), use of intra-operative ECoG (IRR:1.73, 95% CI [1.06-2.81], p = 0.028), and absence of IEDs in postoperative EEG (IRR: 1.41, 95% CI [1.18-1.70], p < 0.001) were positive predictors for a favorable outcome. CONCLUSION: Many patients with drug-resistant lesional epilepsy showed a favorable response to surgery. We believe that resective epilepsy surgery in low-income settings is a major treatment option. The high frequency of patients with drug-resistant epilepsy in developing countries is associated with high rates of morbidity and mortality. Hence, strategies to increase access to epilepsy surgery in these settings are urgently needed.

The correlation between cluster seizures and findings of magnetic resonance imaging in drug refractory epilepsy patients.

BACKGROUND: Epilepsy is a chronic neurologic condition and affects peoples at all ages. Seizure clusters are generally referred to seizures that occur at close intervals with complete recovery between attacks. Various studies have reported a variety of frequencies and risk factors for this condition. METHOD: We designed a study to determine the frequency of seizure cluster and to determine neuroimaging findings in these patients and also to evaluate the Correlation between Cluster Seizures and Findings of Magnetic Resonance Imaging in Drug Refractory Epilepsy patients. RESULTS: After analyzing data from 568 refractory epilepsy patients, we found that the prevalence of cluster seizure variant is 14.43%. 29.26% of patients with a history of cluster seizure had no obvious abnormal MRI findings whereas 14.40 % of patients without history of cluster seizure had no obvious abnormal MRI findings (P-value <0.05). Compared to Drug Refractory Epilepsy patients without history of seizure clusters, patients with a history of seizure clusters had less abnormal MRI findings, less Mesial Temporal Sclerosis, and more Focal Cortical Dysplasia in Magnetic Resonance Imaging (p value <0.05). CONCLUSIONS: Seizure cluster has a significant negative impact on the quality of life of patients. According to results of this study it seems that brain MRI findings of drug refractory epilepsy patients with a history of seizure clusters are different from brain MRI findings of drug refractory epilepsy patients without a history of seizure clusters. mesial temporal sclerosis is less frequent and focal cortical dysplasia is more frequent in brain MRI of drug refractory epilepsy patients with a history of seizure clusters compared to drug refractory epilepsy patients without a history of seizure clusters.

Comparison of the Efficacy and Safety of Pregabalin and Duloxetine in Taxane-Induced Sensory Neuropathy: A Randomized Controlled Trial.

BACKGROUND AND OBJECTIVE: Taxane-induced peripheral neuropathy (TIPN) is a main toxicity of taxanes with no effective treatment. This study aimed to compare the efficacy and safety of pregabalin (150 mg daily) and duloxetine (60 mg daily) for managing TIPN in breast cancer patients. METHODS: This randomized, double-blind, Phase II clinical trial was carried out at a chemotherapy center affiliated to Mazandaran University of Medical Sciences. Patients with breast cancer who received paclitaxel or docetaxel and had a grade 1 or more neuropathy (based on the National Cancer Institute Common Terminology Criteria for Adverse Events version (NCI-CTCAE v4.03), and who had score 4 or higher neuropathic pain severity [based on the visual analog scale (VAS)] were enrolled. Response to treatment was assessed based on improvements in the VAS, NCI-CTCAE, and Patient Neurotoxicity Questionnaire (PNQ) scores during a 6-week trial. RESULTS: Both interventions were effective in decreasing TIPN compared to baseline. At Week 6, the VAS scores were improved in 37/40 (92.5%) and 16/42 (38.1%) of the patients in the pregabalin and duloxetine groups, respectively (p < 0.001). Improvement in NCI-CTCAE sensory neuropathy was also more significant with pregabalin (37/40; 92.5%) in comparison to duloxetine (13/42; 31%) (p < 0.001). Pregabalin was also more beneficial than duloxetine in improving the PNQ scores by 36/40 (90%) and 13/42 (31%), respectively (p < 0.001). Both interventions were tolerated well with mild adverse events. CONCLUSIONS: Both pregabalin and duloxetine were well tolerated and efficacious in relieving neuropathic pain, however a 60 mg dose of duloxetine is inferior to a 150 mg dose of pregabalin.

Taxane-induced peripheral neuropathy and quality of life in breast cancer patients.

PURPOSE: Taxane-induced peripheral neuropathy (TIPN) is a common and bothersome toxicity. This study aimed to determine the incidence and severity of TIPN in patients with breast cancer and to investigate the relationship between TIPN and quality of life. METHODS: A total of 82 breast cancer patients with TIPN symptoms were included in this study. The criteria of National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE v4.03) and the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30, version 3.0) were used to evaluate grading of sensory neuropathy and quality of life, respectively. Analysis of the data was done by IBM SPSS statistics version 23. RESULTS: A total of 346 patients received taxane-based chemotherapy and 82 patients (23.7%) experience TIPN. The mean (SD) global health status/quality of life, physical functioning, role functioning, and pain subscales were 60.63 (5.26), 80.64 (9.05), 81.77 (10.41), and 43.88 (11.27), respectively. There were significant negative correlations between global health status/quality of life, physical functioning, and role functioning subscales with the grade of neuropathy (r = -0.33, -0.80, and -0.61, respectively) and positive correlation between pain subscale and the grade of neuropathy (r = 0.70). CONCLUSION: This study shows a clear association between TIPN and worsened quality of life. These findings emphasize on detecting and management of TIPN in an effort to improve the quality of life of breast cancer patients.

The Role of Interictal Epileptiform Discharges in Epilepsy Surgery Outcome.

BACKGROUND: Epilepsy surgery is a fundamental treatment in refractory epilepsy. Video electroencephalographic (v-EEG) monitoring plays an essential role in presurgical evaluation of patients. However there are reports of favorable outcome based on interictal and magnetic resonance imaging (MRI) findings without any need for v-EEG monitoring in patients with temporal lobe epilepsy (TLE). This study aimed to investigate the prognostic effect of concordance between interictal findings and ictal and MRI data on postsurgical outcome of TLE and extratemporal lobe epilepsy (ETLE). METHODS: A retrospective study was conducted on 199 patients with refractory focal epilepsy who were admitted for presurgical evaluation. The concordance between irritative zone (IZ) and seizure onset zone (SOZ) and also IZ and MRI lesion was registered, and subsequently the prognostic effect of relevancy on 1-year follow-up result based on Engel criteria was investigated. RESULTS: In TLE and ETLE regarding relevancy between IZ and SOZ, 77.8% and 73.2% were concordant, 2.5% and 0% were discordant, and 19.6% and 26.8% had overlap, respectively. Concordance between IZ and MRI lesion was found in 76.6% and 51.2% of patients with TLE and ETLE while discordance was recorded in 2.5% and 12.2% and overlap registered in 20.9% and 36.6%, respectively. The concordance of interictal findings had no effect on postsurgical outcome of patients with TLE and ETLE. CONCLUSIONS: Our study showed that concordance of IZ with SOZ and MRI has no independent effect on postsurgical outcome of patients with TLE and ETLE. We suggest that excluding exceptional cases, v-EEG monitoring should be considered as the mainstay of presurgical evaluation.

Evaluation of dual pathology among drug-resistant epileptic patients with hippocampal sclerosis.

PURPOSE: Dual pathology (DP) is defined as simultaneous presence of hippocampal sclerosis (HS) and any other pathology in the brain. Since this is a less probed concept, we aimed to evaluate the frequency and characteristics of DP among drug-resistant epileptic patients with HS. METHODS: This is a cross-sectional study conducted during 2007-2016 in Kashani Comprehensive Epilepsy Center, Isfahan, Iran. Patients with diagnosis of drug-resistant epilepsy and HS were enrolled in the study, and demographic data, seizure semiology, EEG findings, and MRI findings were collected. We compared these variables between three groups of DP, unilateral HS, and bilateral HS. RESULTS: Of the 200 enrolled cases, 29 patients (14.5%) had DP and 21 patients (10.5%) had bilateral HS; the remaining patients had unilateral HS. The average age of patients with DP was 30.03, and 65.5% of them were male. Patients with DP had more EEG discharges from regional and multi-focal sites compared to unilateral HS (P value < 0.001). Also, complex partial seizure (CPS) was more commonly presented in patients with unilateral HS (96.8%). Comparison of disease characteristics between DP and bilateral HS showed no difference in most categories (P > 0.05). CONCLUSIONS: We found DP among 14.5% of our drug-resistant epileptic patients with HS. DP patients mostly presented with CPS and had high proportion of ictal and interictal EEG discharges from regional and multi-focal areas. Gliosis and focal cortical dysplasia were the most common pathologies among DP patients. Patients with DP showed a similar behavior to bilateral HS in many features.

The effect of pregabalin and duloxetine treatment on quality of life of breast cancer patients with taxane-induced sensory neuropathy: A randomized clinical trial.

BACKGROUND: The primary side effect of adjuvant chemotherapy with taxanes is the taxane-induced peripheral neuropathy (TIPN), which may have substantial negative impacts on patients' quality of life (QOL). We investigated the effect of pregabalin and duloxetine on QOL of breast cancer patients who experienced TIPN. MATERIALS AND METHODS: This was a randomized, double-blind clinical trial conducted at a chemotherapy center of Mazandaran University of Medical Sciences, Sari, Iran. Breast cancer patients 18 or more years old were included if they received paclitaxel or docetaxel and experienced neuropathy grade one or higher; and neuropathic pain score of four or more. Patients were treated with pregabalin or duloxetine until 6 weeks. Assessment of sensory neuropathy and QOL was performed at baseline, and 6 weeks after the initiation of the treatment. RESULTS: At baseline, the mean score of global health status/QOL scale for pregabalin and duloxetine groups were 61 (standard deviation [SD]; 5.11) and 60.28 (SD; 5.44), respectively (P = 0.54). After 6 weeks, both interventions were associated with improvement of global QOL compared to baseline. The global health status/QOL score was not different between two groups after 6 weeks. While the emotional functioning was improved more favorably with duloxetine (P < 0.001); pregabalin was associated with more improvement in insomnia and pain scores (P = 0.05 and P < 0.001, respectively). CONCLUSION: Pregabalin as well as duloxetine improve the global QOL of breast cancer patients with TIPN. Different effects of treatments on subscale of QLQ-C30 could help clinicians to select the appropriate agent individually.

An Undiagnosed Case of Hypothalamic Hamartoma with a Rare Presentation.

Background. Hypothalamic hamartomas (HHs) are rare tumor-like malformations that may present with complex partial seizures refractory to anticonvulsants in adulthood. The condition may be misdiagnosed because of rarity. Case Presentation. We report a 25-year-old man with complaint of seizures presented by falling, tonic spasm of limbs, oral automatism, vocalization, and hypermotor activities. His seizures started at the age of one month and presented as eye deviation and upper limbs myoclonic jerk, followed by frequent seizures with variable frequency. The patient had delayed developmental milestones and was mentally retarded. He was hospitalized and underwent video-EEG monitoring and neuroimaging, and the diagnosis of HH was made. The patient became candidate for surgery after that. Conclusion. In this case, the underlying etiology of seizures was diagnosed after 25 years. HH is a rare condition and neurologists may encounter very small number of these cases during their practice. Therefore, they should consider it in patients who present with suspected signs and symptoms.

Prognostic value of ictal onset patterns in postsurgical outcome of temporal lobe epilepsy.

Background: To investigate ictal onset patterns (IOP) in scalp electroencephalography (EEG) of patients with temporal lobe epilepsy (TLE) and their prognostic effect on the postoperative outcome. Methods: We conducted a retrospective cohort study between 2011 and 2015 in our referral Epilepsy Surgery Center enrolling adult patients with refractory TLE and a visible epileptogenic lesion in magnetic resonance imaging (MRI), who underwent epilepsy surgery. Demographic, clinical and MRI findings were collected and ictal findings during video-EEG monitoring were reviewed in detail. The correlation between preoperative findings and the postsurgical outcome was analyzed. Results: We reviewed 303 seizures in 93 patients. Rhythmic theta and rhythmic spike/sharp and wave were respectively the most common initial ictal pattern and late significant discharges. Engel class I outcome was observed in 88.2% of patients. Female sex, aura, the absence of secondary generalization, rhythmic theta as initial ictal pattern and concordance of ictal-interictal EEG findings were correlated with favorable 1-year postsurgical outcome. Conclusion: Preoperative clinical and EEG findings can provide valuable information regarding postsurgical prognosis in TLE patients.

Ischemic stroke as a rare manifestation of aluminum phosphide poisoning: a case report.

Aluminum phosphide (AlP) is a solid fumigant which is widely used for a suicide attempt in Iran. Although neurologic symptoms are commonly reported, cerebrovascular stenosis is rare in AlP poisoning. We described ischemic stroke as a delayed complication of AlP intoxication. A 30-year-old man was admitted because of sudden onset left side hemiplegia, 11 days after intentional ingestion of three rice tablets. Investigations revealed in situ thrombosis in right middle cerebral artery (MCA) while other causes of stroke in young adults were excluded. Ischemic stroke should be considered as a delayed complication of AlP intoxication even after the acute phase of intoxication.

Pediatric multiple sclerosis with primary progressive course--report of a retrospective cohort study in Iran.

The aims of this study were to suggest the rate of primary progressive (PP) subtype of pediatric onset multiple sclerosis (MS) in Isfahan, Iran, and describe its clinical and paraclinical features. The data of patients were retrieved from Isfahan MS Society (IMSS) database from April 2003 to August 2011. Among 3,843 MS patients of Isfahan who have been registered in IMSS, 260 patients had onset symptom when younger than the age of 18 years, of whom, 11 patients had a PP course (4.23%). The mean age at onset in pediatric primary progressive multiple sclerosis (PPMS) was 16 years (range: 13 to 17) with female preponderance (2.66:1) and disease duration of 4.73 ± 3.03 years. Ataxia was the most frequent initial symptom (7/11). Additionally, the mean Expanded Disability Status Scale and progression index was 4.31 ± 0.60 and 1.50 ± 1.21, respectively. Cerebrospinal fluid analysis showed oligoclonal immunoglobulin G bands in seven patients. Magnetic resonance imaging (MRI) demonstrated periventricular lesions in all 11 patients and spinal lesions in 9 patients. Exposure to parental smoking was recorded in seven individuals. In conclusion, PPMS is an uncommon subtype of pediatric onset MS. Cerebral lesions are more common MRI findings in pediatric PPMS patients than that in adults. The course of PPMS seems to be more progressive in the pediatric population than in adults.

Surgical approach to hydrocarbon injection in upper extremities: case series.

BACKGROUND: Hydrocarbon injection, which mostly occurs in the upper extremity, is commonly seen in domestic and industrial accidents, or attempted suicide. Surgical approach to chemical cellulites and other complications in these patients is controversial. METHOD: This survey has been carried out on 21 patients admitted to general surgery unit of Loqman Hakim hospital, Tehran, Iran with the complaint of hydrocarbon injection in 2001-2005. RESULTS: The most common injected material was petroleum (in 8 patients). Anterior forearm was the most common injection site (in 16 patients). All of the patients had inflammation, swelling, and localized tenderness. Leukocytosis was present in 18 of 21 patients. Compartment syndrome happened in 13 patients; 5 with necrotizing fasciitis. All of the patients with compartment syndrome underwent fasciotomy and debridement. Split thickness skin graft was done for 10 patients after 2 weeks of admission. There was no mortality or limb loss during the study period. CONCLUSIONS: Prevention of the systemic complications, hospitalization, close monitoring and treatment of chemical cellulites are the main parts of the management of patients with hydrocarbon injection. Surgical intervention is recommended when compartment syndrome or other local complications occur.
