Effect of Adjuvant Electroconvulsive Therapy Compared to Antipsychotic Medication Alone on the Brain Metabolites of Patients with Chronic Schizophrenia: A Proton Magnetic Resonance Spectroscopy Study

Objective: Schizophrenia is a common psychiatric disease and is characterized by changes in several brain metabolites detectable by magnetic resonance spectroscopy (MRS). Electroconvulsive therapy (ECT) is a general method of management for most severe psychiatric conditions that may play a role in changing the brain metabolites. This study examined the effectiveness of adjuvant ECT with oral medication compared to that of oral second generation antipsychotic medication alone on brain metabolites in patients with chronic schizophrenia. Method: This study was conducted on 20 patients with chronic schizophrenia who were admitted to a hospital; of them, 10 underwent ECT as an adjuvant therapy with oral medication at least 8 times, and 10 patients were given a second- generation antipsychotic therapy drug (risperidone and olanzapine) without ECT for at least 4 weeks. MRS was used to assess brain metabolites, including N-acetyl aspartate (NAA), choline (Cho), creatine (Cr), myoinositol (MI), and Glx (glutamate [Glu] and glutamine [Gln]), in the left prefrontal cortex, left thalamus, left hippocampus, and left occipital cortex. Differences between the 2 groups were not significant, except for method of treatment. Results: The NAA/Cr ratio in the left prefrontal cortex was significantly higher in ECT-treated patients (P = 0.035). In addition, the Cho/Cr ratios in the left prefrontal cortex and left thalamus were statisticaly lower in the ECT-treated patients than those treated with oral antipsychotic drugs alone (P = 0.019). No statistically significant changes were observed between the 2 groups in other sites of the brain. In addition, no statistically significant differences were detected between the 2 groups in SAPS and DES scores. Conclusion: Compared to oral antipsychotic drug treatment, ECT had improving effects on at least 2 metabolites in the brains of patients with schizophrenia. Therefore, ECT may have a neuroprotective effect in these patients

A Ten-Year Study of Prostate Cancer: A Southern Iranian Experience

Background:Prostate canceris the most common malignancy among the male population in the United States and the 3rd most common non-skin cancer among men in Iran. Its prevalence has shown a rising trend in recent decades. The aim of this study was to report the epidemiological features of prostate cancer in patients referred for prostate biopsy in the south of Iran and to evaluate the accuracy of the levels of the prostate-specific antigen (PSA) and the PSA-density (PSAD) as well as the extension of the disease in the prediction of the biological behavior of prostate cancer. Methods:This is a retrospective study on the medical records of 1982 consecutive patients who underwent transrectal ultrasound-guided biopsy due to an abnormal digital rectal examination and/or an elevated PSA level following referral from the Urology Ward to the Radiology Department of ShahidFaghihi Hospital in Shiraz, southern Iran, between December 2003 and July 2014. Results:The overall cancer detection rate was 33.1%. Although the cancer was more prevalent among the elderly patients, a significant fraction (7%) of the patients were aged < 55 years. The sensitivity and specificity of the PSA were 97.4% and 8.7% and those of the PSAD were 82.9% and 52%, respectively. Of the 637 patients with prostate cancer, 250 (39.2%) had unilateral disease, 378 (59.4%) had bilateral disease, and 9 (1.4%) had inner-gland involvement. Most of the patients with bilateral involvement had high-grade Gleason scores. Conclusion: Our study underlines the relationship between age and the frequency of cancer; the levels of the PSA and the PSAD and the Gleason score; and the extent of tumor involvement and the grade of prostate cancer and also highlights the significance of screening, especially in younger patients

Risk factors associated with long covid syndrome: A retrospective study

Background: Recently, people have recognized the post-acute phase symptoms of the COVID-19. We investigated the long-term symptoms associated with COVID-19, (Long COVID Syndrome), and the risk factors associated with it. Methods: This was a retrospective observational study. All the consecutive adult patients referred to the healthcare facilities anywhere in Fars province from 19 February 2020 until 20 November 2020 were included. All the patients had a confirmed COVID-19 diagnosis. In a phone call to the patients, at least three months after their discharge from the hospital, we obtained their current information. The IBM SPSS Statistics (version 25.0) was used. Pearson Chi square, Fisher’s exact test, t test, and binary logistic regression analysis model were employed. A P value of less than 0.05 was considered to be significant. Results: In total, 4,681 patients were studied, 2915 of whom (62.3%) reported symptoms. The most common symptoms of long COVID syndrome were fatigue, exercise intolerance, walking intolerance, muscle pain, and shortness of breath. Women were more likely to experience long-term COVID syndrome than men (Odds Ratio: 1,268; 95% Confidence Interval: 1,122-1,432; P=0.0001), which was significant. Presentation with respiratory problems at the onset of illness was also significantly associated with long COVID syndrome (Odds Ratio: 1.425; 95% Confidence Interval: 1.177-1.724; P=0.0001). A shorter length of hospital stay was inversely associated with long COVID syndrome (Odds Ratio: 0.953; 95% Confidence Interval: 0.941-0.965; P=0.0001). Conclusion: Long COVID syndrome is a frequent and disabling condition and has significant associations with sex (female), respiratory symptoms at the onset, and the severity of the illness

Use of endoanal ultrasound as complimentary evaluation for detection of anal sphincter injury after vaginal birth

Purpose: Anal sphincter injury after delivery is the main factor in the pathogenesis of fecal incontinence. Clinical obvious and specific injury to anal canal sphincter is seen in 3% of vaginal deliveries. There are many women who do not have a clear and specific laceration but they are damaged by sphincter muscles of anal canal. The purpose of the present study is to investigate the frequency of occult anal sphincter injury after vaginal delivery by Endo-anal sonography. Methods: Fifty women with first pregnancy were assessed at 27–33 weeks of pregnancy, and at 6 weeks and 6 months after vaginal delivery by questionnaire, examination and Endo-anal sonography. Women age, duration of delivery, the effect of epidural anesthesia, episiotomy and birth weight were studied and Endo-anal sonography results were recorded. Anal manometry was performed for all mothers before delivery and 5 ones with sphincter injury at 6 months and 3 years after delivery. Results: Five (10%) patients, with mean age 29.4 ± 6.5 years, mean neonatal weight of 3874 ± 287, and mean duration of delivery 11.6 ± 1.51 h, had signs of sphincter injury in Endo-anal sonography. The injury was persisted at six months after delivery. Also, significant differences were seen between anal manometry before delivery and 6 months and 3 years after delivery (p = 0.006 for mean squeezing pressure) in the five mothers. Conclusion: Endo-anal sonography might be a good screening tool for early detection of postpartum anal sphincter damages. However, further prospective cost benefit studies should be performed to propose it as a standard of care. Resumo: Finalidade: A lesão de esfíncter anal após o parto é o fator principal na patogênese da incontinência fecal. Observa-se uma lesão clínica óbvia e específica ao esfíncter no canal anal em 3% dos partos vaginais. Em muitas mulheres não se percebe uma laceração nítida e específica, mas houve lesão nos músculos esfinctéricos do canal anal. A finalidade desse estudo é investigar a frequência de lesão oculta de esfíncter no canal anal em seguida ao parto vaginal por meio da ultrassonografia endoanal. Métodos: Cinquenta mulheres primíparas foram avaliadas no período de 27-33 semanas de gestação e também a 6 semanas e 6 meses após o parto vaginal por meio de questionário, exame e ultrassonografia endoanal. Foram anotados a idade das pacientes, a duração do parto, o efeito da anestesia epidural, episiotomias e peso do bebê ao nascer; também foram registrados os resultados da ultrassonografia endoanal. Antes do parto, todas as gestantes foram submetidas a um exame de manometria; e 5 mães com lesão esfinctérica também passaram por esse procedimento a 6 meses e 3 anos após o parto. Resultados: Cinco (10%) pacientes, com média de idade = 29,4 ± 6,5 anos, peso médio do bebê ao nascer = 3874 ± 287 gramas e duração média do parto = 11,6 ± 1,51 horas, apresentavam sinais de lesão esfinctérica ao exame por ultrassonografia endoanal. Seis meses após o parto, as lesões persistiam. Também foram observadas diferenças significativas entre a manometria anal antes do parto e a 6 meses e 3 anos após o parto (p = 0,006 para média de pressão de contração) nas cinco mães. Conclusão: A ultrassonografia endoanal pode ser um bom instrumento de triagem para a detecção precoce de lesões do esfíncter anal no pós-parto. Contudo, é importante que sejam realizados novos estudos prospectivos e de custo-benefício, para que essa técnica possa ser proposta como padrão terapêutico.

Generalized exfoliative skin rash as an early predictor of supratherapeutic voriconazole trough levels in a leukemic child: A case report

Background and Purpose: Skin rashes, mostly seen in children and adolescents, are considered among the most common side effects of azole antifungals. Although therapeutic concentrations of voriconazole (VCZ) have been documented for infected skin, there is no evidence specifying whether specific dermatologic side effects could predict high VCZ serum concentration, especially in high-risk leukemic children. Case report: Herein, we report a unique skin side effect of VCZ in a 5-year-old boy with T-cell acute lymphoblastic leukemia (ALL) referred to Amir Medical Oncology Center in Shiraz, Iran. The patient experienced erythroderma and macular rashes shortly after VCZ consumption, leading to generalized exfoliative skin rashes. Concurrent to these skin manifestations, VCZ serum concentration reached the supratherapeutic levels despite the recommended VCZ doses. As a result, VCZ was withheld, and the patient was treated with caspofungin. The lesions were resolved gradually within 2 weeks, and the patient successfully completed his treatment course with caspofungin. Conclusion: The unique case presented in this study emphasizes the need for a high index of suspicion for VCZ toxicity in any patient with atypical dermatologic manifestations, especially generalized exfoliative skin rashes. Based on this report, VCZ supratherapeutic concentration could be predicted early in the course of treatment. Additional therapeutic dose monitoring should be considered to establish a confirmatory diagnosis. It is required to further investigate the toxic effect of high VCZ concentration on the skin epithelium

Potential voriconazole associated posterior reversible leukoencephalopathy in children with malignancies: Report of two cases

The fungal infection has become severe morbidity amongst patients with malignancy. Voriconazole, a new generation of triazole, has shown excellent results in treating invasive fungal infections. Herein, we report two cases of posterior reversible encephalopathy syndrome (PRES), which induced after voriconazole exposure. Magnetic resonance imaging, and the serum level of voriconazole were investigated in both patients to assess toxicity. The role of methotrexate, as one of the possible causes of PRES, is weakened significantly through precise assessing diffusion-weighted images on magnetic resonance imaging. These unique cases emphasize that voriconazole can induce PRES even at therapeutic levels. Therefore, in the case of neurotoxicity, PRES must be considered, and voriconazole should discontinue. The prognosis seemed promising when voriconazole stopped immediately after clinical suspicion

Epidemiological and clinical features of 2019 novel coronavirus diseases (COVID-19) in the South of Iran

BACKGROUND: In March 2020, the WHO declared the novel coronavirus (COVID-19) outbreak a global pandemic. Although the number of infected cases is increasing, information about its clinical characteristics in the Middle East, especially in Iran, a country which is considered to be one of the most important focal points of the disease in the world, is lacking. To date, there is no available literature on the clinical data on COVID-19 patients in Iran. METHODS: In this multicenter retrospective study, 113 hospitalized confirmed cases of COVID-19 admitted to university affiliated hospitals in Shiraz, Iran from February 20 to March 20 were entered in the study. RESULTS: The mean age was 53.75 years and 71 (62.8%) were males. The most common symptoms at onset were fatigue (75: 66.4%), cough (73: 64.6%), and fever (67: 59.3%). Laboratory data revealed significant correlation between lymphocyte count (P value = 0.003), partial thromboplastin time (P value = 0.000), international normalized ratio (P value = 0.000) with the severity of the disease. The most common abnormality in chest CT scans was ground-glass opacity (77: 93.9%), followed by consolidation (48: 58.5%). Our results revealed an overall 8% (9 out of 113 cases) mortality rate among patients, in which the majority was among patients admitted to the ICU (5: 55.6%). CONCLUSION: Evaluating the clinical data of COVID-19 patients and finding the source of infection and studying the behavior of the disease is crucial for understanding the pandemic
