Primary adrenal lymphoma: a systematic review

Fewer than 200 cases of primary adrenal lymphoma (PAL) have been reported. We have systematically reviewed all 187 cases of PAL reported in the English literature until June 2013, from which we drew the following conclusions: PAL is typically a highly symptomatic and aggressive, metabolically hyperactive, hypovascular, hypoechoic (and heterogeneous on ultrasound), hypodense (with slight to moderate enhancement on computed tomography), high-grade lymphoma, primarily affecting elderly males and presenting with large bilateral adrenal masses. Most cases have adrenal insufficiency, B-symptoms, and elevated lactate dehydrogenase. Hepatosplenomegaly, lymphadenopathy, concurrent or prior immune dysregulation, and bone marrow involvement are uncommon. Epstein–Barr virus positivity is observed in more than half of cases and the disease is disseminated at presentation in 18 % of cases. The two most common WHO 2008-defined PAL subtypes are diffuse large B cell lymphoma (78 %) and peripheral T cell lymphoma (7 %). The prognosis of PAL has improved with the advent of rituximab-containing chemotherapeutic regimens. According to our results, administration of chemotherapy and adrenal insufficiency are significant independent predictors of prognosis.     

Third national surveillance of risk factors of non-communicable diseases (SuRFNCD-2007) in Iran: methods and results on prevalence of diabetes, hypertension, obesity, central obesity, and dyslipidemia

Background  

The burden of non-communicable diseases is rising globally. This trend seems to be faster in developing countries of the Middle East. In this study, we presented the latest prevalence rates of a number of important non-communicable diseases and their risk factors in the Iranian population.     

Iron status in women with and without gestational diabetes mellitus

ObjectiveGestational diabetes mellitus (GDM) affects approximately 7% of all pregnancies. Pregnancy, mostly because of the mitochondria-rich placenta, is a condition that favors oxidative stress. A transitional metal, especially iron, which is particularly abundant in the placenta, is important in the production of free radicals. Also, studies have shown that free radicals have a role in GDM. As there are little data about iron status in GDM, this study was performed to compare iron status in GDM and control group.Research Design and MethodsIn this case-control study, 34 women with diagnosed GDM were compared with 34 non-GDM women in the control group at 24–28 weeks of pregnancy in terms of iron status, including ferritin, serum iron, total iron-binding capacity (TIBC), hemoglobin (Hb), mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH).ResultsIn this study, concentration of serum ferritin, iron, transferrin saturation and hemoglobin, MCV, and MCH was significantly higher in the GDM group and TIBC was significantly lower in this group (P<.05). No significant association was observed with the other variables including familial history of diabetes and GDM.ConclusionOur findings indicate an association between increased iron status and GDM. The role of iron excess from iron supplementation in the pathogenesis of GDM needs to be examined.     

Myalgia Cruris Epidemica: an unusual presentation of dengue fever

We describe a 5-year-old girl who had sudden onset difficulty in walking after 3 days of febrile illness. In the emergency department her creatine kinase level was elevated but urine myoglobin was normal. She was diagnosed as having benign acute childhood myositis. Because of poor oral intake and dehydration, she was admitted to the pediatric ward. The next day she had a petechial rash over the antecubital fossa, and dengue IgM back was positive. She was treated conservatively and recovered uneventfully. Despite dengue fever being endemic in Malaysia, this is the first case report of myositis following dengue infection in Malaysia.     

Erythropoietin improves spatial learning and memory in streptozotocin model of dementia

Alzheimer's disease is associated to impairments of learning and memory. Because studies demonstrated that erythropoietin has positive effects on central nervous system, the aim of this study was to evaluate the effect of erythropoietin on spatial learning and memory in a well defined model for Alzheimer's disease. Rat model of Alzheimer's was created by injecting streptozotocin in lateral ventricles of the brain. Two weeks later, the rats were assessed through passive avoidance learning test to confirm the induction of Alzheimer's. After that, they received erythropoietin (5000 IU/kg) every other day, for two weeks and then spatial learning and memory were assessed by a 5-day protocol of Morris water maze test in them. The results showed that streptozotocin severely damaged learning and memory in rats. Erythropoietin had no significant effect in the control rats; however, it significantly improved learning and memory in rats with Alzheimer's disease, as the task performance of the rats treated with erythropoietin was like the control group. The results suggest that erythropoietin can be considered as an effective treatment for neurodegenerative damages.     

Passionflower in the treatment of generalized anxiety: a pilot double-blind randomized controlled trial with oxazepam

OBJECTIVE: Passionflower (Passiflora incarnata) is a folk remedy for anxiety. A double-blind randomized trial compared the efficacy of Passiflora incarnata extract with oxazepam in the treatment of generalized anxiety disorder. METHODS: The study was performed on 36 out-patients diagnosed with GAD using DSM IV criteria. Patients were allocated in a random fashion: 18 to the Passiflora extract 45 drops/day plus placebo tablet group, and 18 to oxazepam 30 mg/day plus placebo drops for a 4-week trial. RESULTS: Passiflora extract and oxazepam were effective in the treatment of generalized anxiety disorder. No significant difference was observed between the two protocols at the end of trial. Oxazepam showed a rapid onset of action. On the other hand, significantly more problems relating to impairment of job performance were encountered with subjects on oxazepam. CONCLUSION: The results suggest that Passiflora extract is an effective drug for the management of generalized anxiety disorder, and the low incidence of impairment of job performance with Passiflora extract compared to oxazepam is an advantage. A large-scale trial is justified.
