Simultaneous Onset of Chickenpox and Scarlet Fever: a Case Report
M Karimi
Journal of Shahid Sadoughi University of Medical Sciences , 2012,
Abstract: Introduction: Chickenpox is a contagious febrile illness with rash that is caused by varicella zoster virus. Most children up to age 15 are infected with the virus. Scarlet fever is caused by erythrogenic toxin of streptococcus group A and usually causes skin reactions such as fine red and often itchy papules on the trunk and extremities as well as skin redness, especially on the groin and forearm. Case: Patient is a 3-year-old girl that two days after chickenpox while she had active lesions of the chickenpox, was infected with scarlet fever. Skin lesions at different stages along with the clinical symptoms confirmed the diagnosis of chickenpox. Chickenpox is a febrile illness, more contagious and associated with the rash, which rarely has been reported with scarlet fever. Macular lesions spreading all over the body especially the trunk, with strawberry red tongue and exudative lesions of tonsils with good response to penicillin confirmed the complication of scarlet fever following chickenpox. Rarely scarlet fever is a complication of chickenpox and symptoms of both conditions may be seen simultaneously. Considering that diagnosis of both diseases are based on clinical findings, so physicians should start the appropriate treatment if they have clinical suspicion.

Pregnancy is the most common cause of muscle cramps that usually occur in the second trimester of pregnancy. Although the reasons of the spasms had not been determined, the imbalance between the absorption and elimination of serum electrolytes such as Ca, Mg and potassium and also insufficiency of some vitamins and probably the changes in activities of motor neurons of spinal cord, can be the source of these problems. The aim of this study was the evaluation of frequency and predisposing factors of leg cramps."n"nMethods: In a cross sectional descriptive analytic study, a group of 400 women in the third trimester of pregnancy were asked to record the symptoms of leg cramp. Their education level and job recorded and their total serum level of Ca and Mg was measured in the first visit. Exclusion criteria included systemic medical conditions such as thyroid disease, diabetes, osteoporosis and prenatal disorders such as gestational diabetes mellitus and preeclampsia and patient cooperation."n"nResults: In our study the prevalence of leg cramp was 54.75%. There was a statistically significant relationship between leg cramp and serum level of magnesium (p=0.04). There was no relation between calcium serum level and leg cramp (p=0.294). The women's age, their nutritional habits and individual characteristics were not signify-cantly related to occurrence of leg cramp."n"nConclusion: Leg cramp is a common symptom in pregnancy and in patients with low serum levels of magnesium, a magnesium supplement can be helpful.
A Randomized, Double-Blind, Trial Of Pilocarpine With Head And Neck Irradiation For Prevention Of Radiation-Induced Xerostomia
Hadad P,Karimi M
Tehran University Medical Journal , 2002,
Abstract: Xerostomia is one of the disturbing side-effects of the radiotherapy to the head and neck region. Pilocarpine has been approved for the treatment;of this condition in the chronic phase, but its use concurrent with radiation could also be beneficial for prevention or reducing the subsequent radiation-induced xerostomia. We undertook to test this hypothesis in a clinical trial."nMaterials and Methods: All 18- to 70-year old patients who were to be irradiated to the head and neck, with both parotid glands in the radiation fields, were eligible for this study. Patients with any medical contraindications for pilocarpine were excluded. Randomization was performed at the start of radiotherapy to either pilocarpine 5 mg three times daily or placebo in a double-blind setting. The drug was started with irradiation and continued until 3 months after the end of radiotherapy. Serum pilocapine levels were measured in a randomly selected number of patients by high-pressure liquid chromatography (HPCL). Xerostomia was evaluated about 6 months after the end of radiation by an analog-scale questionnaire, and the objective grading of xerostomia was recorded by two separate observers."nResults: A total number of 60 patients were randomized into the trial (31 pilocarpine, 29 placebo), mostly with nasopharyngeal carcinomas. Mean parotid dose was 5, 818 cGy. Mean pilocarpine serum level was 14.65 ng/ml. No serous side-effect was observed. Thirty-nine patients were analyzed for xerostomia at a median time of 7 months after radiotherapy, 18 in pilocarpine and 21 in placebo groups (9 patients died and 12 patients did not come back for xerostomia evaluation). Mean subjective xerostomia was 40.3 mm in the pilocarpine group and 57 mm in the placebo group (p= 0.02). Also mean objective xerostomia grade was 2.2 in the pilocarpine group and 2.6 in the placebo group (p= 0.01). Subjective and objective xerostomia results were positively correlated (level 0.01). Age and the parotid dose did not have a significant effect on xerostomia."nConclusion: Pilocarpine as prescribed in our trial produced the standard serum level required, and no serious side-effect. Compared to polacebo, pilocarpine used with radiotherapy could lead to a diminishment of subsequent radiation-induced xerostomia.
FACIAL PALSY AS FIRST PRESENTATION OF ACUTE LYMPHOBLASTIC LEUKEMIA: A CASE REPORT
S. Inaloo,M. Karimi
Iranian Journal of Child Neurology , 2007,
Abstract: Objective Facial paralysis in children is very often idiopathic and isolated facial nervepalsy, resulting from leukemic infiltration is a rare occurrence. Here we present the case of a 14 year-old boy with acute lymphobastic leukemia, who first presented with isolated right side peripheral facial nerveparalysis and was initially diagnosed with Bell’s palsy.Conclusion The presence of Bell’s palsy in young children requires a complete evaluation, keeping in mind the possibility of leptomeningeal disease.
Seroprevalence of Human T-Cell Leukemia Virus Type-1 (HTLV-1) in High Risk Patients
A Karimi,M Nafisi
Journal of Research in Health Sciences , 2011,
Abstract: Background: Human T-lymphotropic virus type I is the etiologic agent of two distinct human diseases, adult T-cell leukemia or lymphoma and a chronic, progressive demyelinating disorder. The aim of this work was to investigate the seroprevalence of HTLV-1/2 among high risk patients (thalassemic and hemodialysis) in Charmahal-va-Baktiari Province, center of Iran. Methods: Using ELISA, a total of 357 serum samples from the patients were tested for HTLV specific antibody during first 6 month of 2005. Seventy percent of samples were thalassemics and 30% were hemodialysis patients. All of the ELISA positive samples were confirmed by Western blotting (WB) analysis. Results: Using ELISA, 27 of 357 (7.6%) serum samples tested positive for HTLV-1 specific antibody of which 18 (7.2%) were thalassemic and 9 (8.4%) were hemodialysis patients. The WB results showed that of 27 samples tested positive by ELISA, 24 (89%) were HTLV-1 and 3 (11%) were not confirmed. Conclusion: The relatively high seroprevalence of HTLV-1 among both thalassemic and hemodialysis patients was determined in this province. This might indicate this region as an endemic area for this virus. However, to approve this hypothesis, the prevalence of this virus in the blood donors has to be determined.
A pilot study on the rate of hemoglobinopathies in hyperbilirubinemic term neonates at Nemazee Hospital Shiraz, Iran
N Pishva,M Karimi
Journal of Shahid Sadoughi University of Medical Sciences , 2006,
Abstract: Introduction: Neonatal hyperbilirubinemia is a common disorder and if untreated is potentially neurotoxic. Methods: In order to investigate the correlation between hyperbilirubinemia and hemoglobinopathies, in a prospective study we studied a total 100 full term neonates at Nemazi Hospital with total bilirubin greater than 15 mg/dl and direct bilirubin less than 1.5mg/dl. Other known causes of hyperbilirubinemia such as G6PD deficiency and blood group incompatibility, septicemia and common metabolic disorders were excluded and then hemoglobin electrophoresis was done. Results: In this study we found two infants with abnormal HbD (2%). None of them had alpha thalassemia or sickle cell anemia. Conclusion: Hemoglobinopathies can be considered as one of the causes of neonatal hyperbilirubinemia. Further studies are recommended on a larger scale in the form of multi center study.
Comparison of Essential Oils of Clove, Thyme and Imazalil Fungicide on Blue Mold ( Penicillium italicum Wehemer) of Citrus Fruits in Storage
Z. Karimi,M. Rahemi
Journal of Science and Technology of Agriculture and Natural Resources , 2008,
Abstract: Pathogens are the most important factors inducing postharvest losses on citrus fruit. Experiments were conducted as a CRD with 4 replications on sweet lime (Citrus limetta) and Valencia orange (Citrus sinensis) in 2003 and 2004. Treatments were pure essential oils of clove and thyme and in 25% ethanol solution at concentrations of 0.1, 0.3 and 0.5% and imazalil (2 ml/l). Results indicated that in the first year, pure essential oils of clove and thyme reduced the decay percentage of blue mold of Valencia orange fruit from 90 % (control) to 0 and 12.5 %, respectively. Pure essential oils of clove and thyme reduced the decay percentage of sweet lime in the first year of experiment from 95 % (control) to 0 and 6 %, respectively. In the second year, with the same treatments decay percentage of blue mold was reduced from 90 % (control) to 0. Solutions of 0.1, 0.3 and 0.5 % of clove and thyme oil extracts in 25 % ethanol solution reduced decay percentage of sweet lime fruits form 85 % (control) to 65, 41 and 26 % for thyme oil and to 60, 30 and 22.5 % for clove oil. Comparison of pure clove and thyme oil extract with imazalil showed that pure clove and thyme oil extracts were not significantly different with fungicide treatment. Treatments of clove and thyme oils in 25 % ethanol treatment were not as effective as fungicide.

The level of this tumor marker is undetectable in menopause women. In patients with gynecological cancer, especially granulosa and epidermal-type (mucinous), ovarian cancers considerable increase in the serum level of inhibin has been reported. The increased level of inhibin has been reported in patients with recurrent ovarian cancer."n"nMethods: We measured total serum inhibin and CA125 tumor marker level in 38 postmenopausal women with pathologically confirmed ovarian cancer before and after surgery out of 51 suspected women. Our control group were postmenopausal women that attended to our clinic for routine gynecologic check up. Both tumor markers were measured in these patients too."n"nResults: Among 38 women with ovarian cancer, 13(34.2%) had elevated serum levels of total inhibin. Among the 16 women with serous adenocarcinoma, 3 patients (18.8%) had elevated serum levels of inhibin. All the three women with granulosa cell tumor had elevated serum levels of inhibin (100%) and 3 of 4(75%) women with mucinous ovarian cancer had the same result. three out of 38 women in control group had elevated serum levels of inhibin. Among all 38 patients, 6(15.7%) showed tumor recurrence, that all were concomitant with rising of both serum CA125 and Inhibin levels (p=0/001)."n"nConclusions: Serum inhibin level is a usefull tumor marker in granulosa cell and in mucinous tumor of ovary. In this study combined inhibin and CA125 assay showed better results in early detection of ovarian cancer in comparison to either CA125 or inhibin alone.
