Abstract

Malaria is a protozoan disease transmitted by the bite of Anopheles mosquitoes. It is the most important of the parasitic disease of human. Most endemic areas are in the tropics. The infection characterized by paroxysms of chills, fever, sweating, anemia, spienimegaly and a chronic relapsing course. In this  report  there  was  an  afebrile  malaria  in  nin  endemic  area. A 60 years old man complaints from abdominal pain, is presented. In exam, the only finding was huge splenomegaly. Evaluations appear malarian parasites in peripheral blood smear. After drug therapy, splenectomy was performed. He followed  for  6  months , didn’t  have any  problems.

Abstract

Wall  and  Shortland (1991) have  shown  that  afferent  fibres  entering  the  cord  in  thoracic  and  lumbar  roots  of  adult  rats  have  branches  that  may  penetrate  up  to  11  segments  caudally  from  the  root  entry  zone.  We  have  investigated  the  extent  of  branching  and  conduction  velocities  of  ascending  and  descending  branches  of  lumbar  and  thoracic  primary  afferent  in  isolated  spinal  cords  of  adults  hamsters  (60-100g) and  juvenile  rats  (30-46 g). Hemisected  spinal  cords  were  maintained  at  cold  artificial  cerebrospinal  fluid (25-27 C) in  which  the  Ca2+  had  been  replaced  by  Mn2+ (2mm) to  block  synaptic  activity. Hamsters, antidromic  conducted  responses  were  obtained  up  to  10  segments  caudal  to  dorsal  roots T6-T7   and  17  segments  rostral  to L3. The  mean  conduction  velocity  was  3.7 m/s  (s.e.m.& 0.4)  for  descending  primary  afferents(n=21) and  9.9 a 1.2 m/s for  ascending  afferents (n=26). In the  rat , antidromic  responses  were  measured  over  4 segments  caudal  and  17  segments  rostral  to  the  L3 dorsal  root. Conclusion  velocities  were  4.4  & 0.5  m/s  and  7.7  &  0.7  m/s  for  descending  and  ascending  branches  respectively (n=4). The  result  were  similar  to  those  reported  by  Wall  &  Shortland , although  the  temperature. Difference  between  the  in  vitro  and  in  vivo  preparations  would  have  resulted  in  approximately  halving  of  the  velocity  in  isolated  cord  preparation.  The  conduction  velocity  of  descending  fibres  was  about  half  fibres  which  may  be  related  to  size  differences  within  the  branches.

Abstract

Refractive error is a disturbance that a picture from one object is not on retina, in this reason picture is not clear. A clear picture is very important for development of visual nervous system to 10 years- old in children. This study was performed in 7 boys school in Arak. Today 753 boys student in the range of 6-11 years-old by the screening test was examined for visual acuity. Prevalence for refractive error was 9.5%. The most prevalence refractive error was pure myopia (56.9%). Family History in 65.3% was positive.

Abstract

Introduction: Amebiasis, Caused  by  Entamoeba  histolytica. Is  one  of  the  three  most  common  prevalent  parasites  that  causes  mortality.
Material  and  Method: This  clinical  trial  was  carried  out  among  45  patients  suffering  from  acute  enteric  amebiasis.  Each  patient  receives  750  mg  metronidazole  and  630  mg  iodoquinol  every  eight  hours  for  one  week, the  following  results  were  obtained.
Results: All of  the  patients  were  completely  treated  at  the  end  of  two  weeks  and  did  not  have  any  sign  of  the  diseases.  Also  two  weeks  after  cessation  of  therapy, stool  test  for  entamobea  histolytica (cyst  and  trophozoite)  was  negative  in  all  of  patients.
Conclusion:  It  seems  by  further  research, we  can  decrease  does  of  medications  and  duration  treatment  in  these  patients.

Abstract

Introduction: Intracomparemental   pressure  were  measured  by  the  wick  catheter  technique  in  32  compartments  of  32  post  traumatic  patients  who  were  clinically  suspected  of  having  acute  compartment  syndromes.  A  pressure  of  zero  millimeters  of  mercury  was  used  as  an  indication  for  normal  compartment  enough  for  being  excluded  in  any  subject.
Material  and  Method:  Signs  and  symptoms  were  examined  in  subjects  based  on  clinical  definitions  before  measuring  intracompartmental  pressures.  Paresthesia, tensness, pain  in  passive  extension, pain  in  active  extension, paralysis, pulselessness, capillary  filling  and  pallor  of  each  subject  were  marked  to  be  used  for  comparison  with  the  value  of  intraucompartmental  pressure.
Results:  Pain  were  present  in  all  subjects  as  the  most  earliest  sign  while  the  skin  pallor  appeared  to  be  the  latest  one.The  lowest  values  of  pressure  were  seen  together  with  pain  and  paresthesia  even  below  the  10  mmHg  among  the  subjects.
In  our  cases  when  ever  the  pressure  values  of  the  affected  compartment  increased.  The  number  of  present  signs  and  symptoms  also  increased.
‍‍Conclusion:  Positive  regression  of  the  mentioned  correlation (r=0.69)  implies  that  the  value  of  intracompartmental  pressure  could  be  indicative  of  the  more  complications  associated  with  more  sign  and  symptoms.
Since  different  signs  and  symptoms  were  present  in  our  subjects  even  with  the  same  value  of  pressure. The  diagnosis  and  apporching  to  compartment  syndromes  may  looks  confusing  so  measuring  intraucompartmental  pressure  by  a  wick  cartheter  seems  to  be  the  cheep.  Available  technique  in  diagnosis  and  management  of  the  cases.

Abstract

Introduction: Sympathetic skin response (SSR) is a central, polysynaptic process which is attributed to sympathetic sudomotor activity. The descinding pathway presents spinal sympathetic system to sweat glands of hands and feets skin. The glands which are affected in reflex sympathetic dystrophy (RSD).
Materials and Methods: In present study, SSRs were recorded from left hands of 62 adult healthy subjects and 12 affected hands of RSD patients in relaxed, supine position at room temperature. Recording were performed by a pair of silver cup electrodes (1cm2) after stimulation of contralateral median nerve at volar aspect of wrist, all connected to a polygraph (physiograph, Narco, USA) to record at least five stimulation recording prosedure in each subject.
Results: Comparison of mean latency, amplitude, duraion and shape of responses in RSD 'patients with normal control group showed significant differences between duration and amplitudes (P=0.0007 and P=0.0001) while the latencies were not different and the shape of responses were mostly biphasic in both RSD and normal group.
Conclusion: Hyperactivities of SSRs in RSD patients are due to sudomotor changes of skin resistance, the SSR may also play a role in the quantitive evaluation of patients with suspected RSD.

Abstract

Introduction: At present, bone graft is unavoidable. In fact although among the all probable bone grafts, the autograft is the best choice, but because of some situations like two coincidence surgery upon one individual, size limitation of autografts (its impossible to get a big piece of graft from patient) increasing the bloodshed contingency, infection etc, made specialist to think about the possible substitution the allograft.
Materials and Methods: Seventeen Newzealandian rabbits were divided into four groups. The graft generator group consisted of one rabbit which was genetically different from other groups. The sham group composed of three rabbits which round autografts about 4 mm in diameter from their tibia were exchanged between rights and left tibias. These grafts were not deantigenized and a 4 mm vacant hole was created to see if it will repair spontaneously within three months. The control group consisted of three rabbits received a round 4 mm tibial autografts which double deantigenization process were done over them. The test group composed of 10 rabbits, received corticocancellous (intramembranous) allografts in left tibia and corticocancellous (endocondral). Allograft in right tibia all grafts were bearing the double deantigenization process.
Results: The rate of prosperity for CCl grafts was 80% and for CCE grafts was 60%.In sham group, healing process was extremely fast (in eight weeks).
In control group, healing process was done slower until six weeks but after 12 weeks it was compensated. The vacant holes were not repaired even after three months. Statistically, there was a meaningless difference between the rates of prosperity in both groups of grafts.
Conclusion: According to statistical assays, although the prosperous numbers of CCl were more than CCE grafts but this difference was meaningless. In the basis of histological assessments if the velocity of healing process is important, the CCI grafts are recommended

Abstract

Introduction: Sex  ratio  is  referred  to  male, female  ration which  is  usually  1.06. This  ratio  is  decreased  during  the  last  few  years. One of  its  reasons  seems  to  be  poisons  and  environmental  pollutions  such  as  cigarette  smoke.  In  this  investigation  we  studied  the relationship  between  fathers  cigarette  smoking  and  sex  ratio  in  children.
Materials  and  Methods: This  is  a  historical  cohort  study.  Study  population  were  neonates  born  in  Arak  hospitals  during  summer  and  autumn  1383.  Sample  size  was  determined  710  neonates, based  on α=5%, β=10%. Sampling  method  was  census  in  which  all  newborns  with  inclusion  criteria  were  selected  and  questionnaires  were  filled. Samples  were  divided  into  three  groups. 1-newborns  with  nonsmoker  fathers  2- newborns  with  smoker  fathers (less  than  20 cigarette  a day) 3- newborns  with  smoker  fathers  (20  or  more cigarettes  a  day) (fathers  cigarette  smoking  at  least  3  months  before  conception  in  second  and third  group). Newborns  sex  ratio  was  determined  in  each  group  and  caparisoned. Data  analysis  was  done  by  frequency, ratio, mean  and  standard  deviation  indexes  and  k-s, leven, t, mann-whitney, chi  square  tests  and  relative  risk, using  SPSS  software. At  all  stages  study  Helsinki  declaration  was  regarded.
Results:  Overall  sex  ratio  was  1.04. This  ratio  was  1.272  for neonates  with  nonsmoker  fathers  and  0.77  for  neonates  with  smoker  fathers. Also  sex  ratio  in  newborns  with  smoker  fathers  using  less  than  20  cigarettes a  day  was  0.846  and  for  those  with  fathers  using 20  or  more  was  0.60. Based on  chi  square  there  was  a  meaningful  relationship  between  the  three  groups (p<0.00001). Relative  risk  in  low  cigarette  group  was  1.23  and  in  high  cigarette  group  1.42.
Conclusion: Based  on  findings  it  seems  that  fathers  cigarette  smoking  near  conception  results  in  decreasing  sex  ratio  and  the  increased  use  of  cigarettes  the  decreased  born of  male  neonates.

Abstract

Introduction: Different strains of Echinococcus Granulosus have been found in endemic areas of Iran. This variation has a significant aspect in the field of medical parasitology and veterinary and also in epidemiology, pathology, control and prevention of Hydatid cyst infection. Morphology, epidemiology and biochemical studies can be carried out to determine Hydatid cyst strains in human and animal origins as host. This study was done to measure different biochemical compositions of liver Hydatid cyst fluids in human, sheep, goat, cattle and camel in 2004.
Materials and Methods: In a cross sectional-analytical study, 112 samples of Hydatid fluids were collected from the liver cysts of different hosts: 16 sheeps, 64 cattles, 12 goats and 10 camels in slaughter houses of Sari and Ghaemshahr and 10 human in Imam hospital. All cyst fluids were centrifuged at 4500 rpm at 4˚C for 45 minutes and the supernatants were analyzed for various biochemical parameters.
Results: Quantitative differences were observed in the levels of Sodium, Glucose, Urea, Alanin Aminotransferase (AST) in liver cystic fluids obtained from different hosts, although these differences were not statistically insignificant. However, differences in the levels of Potassium, Calcium, Triglycerides, Cholesterol, Uric acid, Creatinin, Albumin, Gamma Glutamyl Transferase, Aspartat Aminotransferase (AST) and Creatinine Phosphokinase (CPK) in different Hydatid cyst fluids were statistically significant (P<0.05).
Conclusion: Differences in biochemical composition of different Hydatid cyst fluids suggest the possible existence of more than one strain of Echinococcus Granulosus in human and other intermediate domestic animal hosts in Mazandaran.

Abstract

Introduction: Renal cell carcinoma can be presented with extension of thrombosis to renal vein and inferior vena cava. Management of these patients consists of radical nephrectomy and thrombectomy. In this study we reviewed approach to these patients. Materials & Methods: This is a case series report. During 1379 to 1384, 148 patients diagnosed with renal cell carcinoma (RCC) limited to Gerota’s fascia (stage T3 or less) were admitted to Hasheminejad hospital. Fourteen patients had inferior vena cava (IVC) involvement. Radical nephrectomy as well as thrombectomy was performed in 8 patients. This investigation is done on these 8 patients. Results: Patients' average age was 51.4 years. Six patients were male (75%) and 2 female (25%). The most common symptoms were flank pain (75%), gross hematuria (62.5%) and structural symptoms (50%). All patients had tumors limited to Gerota’s fascia without any distant metastasis. Infrahepatic involvement of IVC was seen in 6 patients and in 2 patients thrombosis extended above the hepatic vein (infrahepatic). No perioperative mortality was seen. Postoperative complications were atelectasia in 2 patients and deep vein thrombosis in one which was treated with conservative management. Conclusion:By skillful surgical approach in patients with RCC and IVC involvement, thrombosis can be completely excised without increasing the rate of complications and longterm survival could be expected.

Abstract

Introduction: Radiotherapy after breast cancer surgery will increase local control of the disease and also increase overall survival. Radiation have some side effects on lung function. In different radiotherapy techniques, these side effects are different. Pulmonary function tests and oxygen saturation are methods for evaluation of these complications. In this study we decide to campare pulmonary complications in two radiotherapy methods. Materials and Methods: In this clinical trial study fifty one patients with breast cancer in stage II and III according to TNM staging system, which were under modified radical mastectomy in Imam Hosein hospital and refered for adjuvant radiotherapy, randomly divided in two groups. In one group patients were treated with three field technique and in others with four field technique. All patients received total dose of 48-50 Gy. For patients, pulmonary function test and pulse oxymetery were done once before initiation of radiotherapy and then one and three months after radiotherapy. Results: Measurement of FEV1 , FVC and show that no significant statistical difference was present between the two groups one month and three months after radiotherapy, also in each of the two groups the amount of FEV1 , FVC and one month after radiotherapy had no significant statistical difference in comparison to baseline tests but FEV1 and FVC after three months was decreased and had significant statistical difference respectively (p<0.001, p<0.006). SO2 had no significant defference between the two groups and also in each group after one and three month of radiotherapy. Conclusion: Locoregional radiotherapy of breast and lymph nodes areas causes a decrease in some parameter of pulmonary function tests but no difference was present between three field and four field techniques.

Abstract

Introduction: Cataract is a type of tarnish observable opacity in different layers constituting the lens and will cause light occlusion or scattering. Necessity for treatment of Cataract via surgery and its close relation with corneal astigmatism, when we applied a new method in cutting and type of cataract surgery, led us to measure the post-operation corneal astigmatism changes in frown incision Phacosection. Materials and Methods: This interventional study has been done on 73 eyes(58 patients). These patients were gone under Cataract surgery via no stitch frown incision scleral tunnel phacosection method. In this study we have 7mm external scleral incision with no suture. They were Keratometerized in four separate periods including pre-operation, one week, one month and three months post- operation. Data was analyzed using independent and paired t-tests. Results: Age, sex and left or right eye had no influence on astigmatism. Mean pre- operation astigmatism was 0.84 ± 0.87D, mean astigmatism 1 week post- operation was 0.27 ± 0.88 D, 1 month post- operation 0.06 ± 0.82 D, and three months post-operation was -0.03 ± 0.85 D (P= 0.0001). Before operation, 80% of the patients did have an astigmatism rate less than 1D that increased to 94.5% in three months period after operation and in 89% of the cases, the ultimate change in astigmatism has been found lower than 1D. The obtained information revealed that there is a meaningful difference between pre-operation astigmatism and the same after one week, one month and three months post-operation(P= 0.0001). Independent sample t and paired t-test were used to analyse data. Conclusion: Our study indicated that the no stitch frown incision scleral tunnel phacosection surgery can reduce pre-op corneal astigmatism, and because of induction of the slight controlled astigmatism we can apply this technique for all cataractic patients

Abstract

Introduction: Typhlitis is a complication in GI tract specially in ileum and cecum due to sever prolonged neutropenia. The syndrome usually occurs in patients with leukaemia who take aggressive chemotherapy or in solid tumor treated with taxane base regimen. The syndrome is accompanied with neutropenia, fever, generalized abdominal pain specially in right lower quadrant and probably a mass in this area. Case: The patient is a 44 year old man which was presented with enlargement of right testes since two months ago. In sonographic evaluation of testes a mass was defined and surgery was done for him, which pathologic result was seminoma. Staging workup was done and in CT Scan a lymph node with size of 35 mm was detected in paracaval area . According to this result the patient received chemotherapy with Cisplatin and Etoposide. One day after completion of chemotherapy he developed abdominal pain , fever and bloody diarrhea and referred to hospital and admitted with diagnosis of typhlitis. Conclusion: Typhlitis is not restricted to a complication of leukaemia treatment or taxane base chemotherapy and other cytotoxic drugs can induce this problem. On the other hand, neutropenia and typhlitis can occur immediately after chemotherapy in sensitive patient and so the time of nadir value of white blood cell is too short.

Abstract

Background: Pain following propofol injection was reported between 28- 90 %. Ketamine have lesser cardiovascular depression effect and also local anesthetic effect. In this study effect of ketamin were analyzed when it given before propofol injection. Methods and Materials: In a randomized double blind clinical trial selected 120 ASA I, II Ptients with 15-65 years old. They were candidated for elective surgery, in half of the patients 100 µg/kg ketamine in 2 ml volume and in another half, 2 ml distilled water were given before propofol injection. Severity of injection pain was evaluated according to 4 scale criteria (none, mild, moderate, or severe) fifteen seconds after injection of 25% of the calculated dose of propofol. Heart rate (HR) and noninvasive blood pressure were recorded before and after propofol injection, immediately and 3 minutes after intubation. The data were analysed by Mann Whitney U, Pooled t-Test and the Chi-squared test. Results: Pain was not sensed in 51.56% and 75% of control and case groups respectively. In cases group showed little decrease in systolic and diastolic pressures after anesthetic induction (p=0.012 and p=0.005). There were upper diastolic pressures after intubation (p=0.00) and 3 minutes after intubation (p=0.000). During intervention heart rate changes had not significant difference between two groups. Conclusion: Ketamine pre-treatment was an effective method in reducing pain and providing hemodynamic stability after propofol induction.

Abstract

Background: Several clinical studies suggest that melatonin is a neuroprotective molecule in neurodegenerative disorders and it showed to be reduced in Multiple Sclerosis (MS) patients. MS also results in blurred vision, papillitis and diplopia. The main objective of the study was to asses the influence of Melatonin supplimentation on visual characteristics in patients with MS.

Materials and Methods: In a Quasi Experimental plan, approved by AUMS ethical Committee, 34 (9 males and 25 females) patients with stable MS were asked to voluntearly participate in the study. All subjects (Mean EDSS 3.14) were taking their routine medications. Visual funtions were evaluated by Visual Functioning Questionnaire (VFO-25) and standard Pattern Reversal Visual Evoked Potentials (PR-VEP) records. Serum Melatonin levels were also measured using an ELISA assay. Recordings were performed after a single dose and after taking 1 tablet every night for 14 days, at the day 16th.

Results: In all subjects, Serum Melatonin levels were significantly enhanced. VFQ scores also showed significat improvement. Except the change in N75 latencies of left eyes, VEP latencies of P100, N145 of both eyes and N75 of right eyes were significantly (p<0.05) reduced.

Conclusion: Our findings suggest significat improvements of visual symptoms of MS after daily intake of 3 mg Melatonin. The results calls for further studies and clinical trails before asking all MS patients to take Melatonin suppliment every night.

Abstract

Background: Breast cancer is both the prevailing malignancy and the most common cause of cancer death among women. Many factors may play a role in the susceptibility to the breast cancer and Oxygen Free Radicals may be one of these. There are various known antioxidant systems against oxidative stress, including ParaoxonaseI. The aim of this study was to investigate the association between rs854560 polymorphism in the PON1 gene in patients with breast cancer.

Materials and Methods: We performed genotyping analysis using polymerase chain reactionrestriction fragment length polymorphism (PCR-RFLP) assay in a case–control study of 83 confirmed breast cancer patients and 100 cancer-free controls in Markazi Province.

Results: In our study of the PON1 gene L55M polymorphism, the LL genotype was found in 2 (2.40%) patients, whereas the LM genotype was found in 69 (83.13%) patients. The MM genotype was present in 12 (14.45%) patients. In the control group, LL, LM and MM genotypes were found in 4 (4%), 81 (81%), and 15 (15%) subjects, respectively. There was no statistically significant difference between patient and control groups in terms of the PON1 gene L55M polymorphism (p= 0.825). Allele distributions were different but this difference did not reach statistical significance (p= 0.920).

Conclusion: We found no association between M55L polymorphism and breast cancer.

Abstract

Background: Biological and epidemiological data indicate that the levels of vitamin D maybe affect the breast cancer risk. Vitamin D plays an important role in cell proliferation, apoptosis and tumor growth suppression. Vitamin D receptor is a critical mediator for the cellular reactions of vitamin D. Some of the epidemiological studies, reviewed the relationship between VDR gene polymorphism ApaI and breast cancer, but the controversial findings have been achieved.

Materials and Methods: In this study, a population-based case-control study including 140 patients and 160 healthy individuals of women in Markazi Province were evaluated using PCR-RFLP approach. Genomic DNA was extracted from blood samples using the salting-out procedure. Polymorphism of interest was determined by PCR-RFLP method using ApaI enzyme and statistical analysis was performed by SPSS software.

Results: Based on the results of this study, distribution of AA genotype in cancer and control groups was, 38.6 and 26.87, for AC genotype 55.00 and 66.87, and finally for CC genotype 6.43 and 6.26 respectively. The results of this study showed no association between ApaI polymorphism of the VDR gene and breast cancer(OR=0.903,CI=95%, 0.29-2.95.)

Conclusion: In this study, we found no association between ApaI polymorphism and breast cancer, which are consistent with the findings of some other researchs. It is necessary to examine a larger population to achieve more definitive results.

Abstract
Background: Selenium supplement has multiple important effects, including anti-inflammatory effect. The aim of this study was to assess the effects of selenium supplement on gene expression of inflammatory cytokines and vascular endothelial growth factor in gestational diabetes.
Materials and Methods: This randomized double blind placebo control trial was performed on 40 patients suffering from GDM aged 18–40 years old. Participants were randomly divided into interventional group receiving 200mg/day selenium supplements (n=20) and control group receiving placebo (n=20) for 6 weeks. Primary outcome was gene expression of inflammatory cytokines and VEGF which were assessed in lymphocyte of GDM patients by RT-PCR method.
Results: After 6 weeks intervention, in comparison with the control group, interventional group showed down regulation of gene expression of tumor necrosis factor alpha (TNF–α) (p=0.02) and transforming growth factor beta (TGF–β) (p=0.01) and up-regulation of gene expression of vascular endothelial (VEGF) (p = 0.03) in lymphocytes of GDM. There was not any significant change following intervention with selenium regarding gene expression of interleukin IL-1 β and IL-8 in lymphocytes of GDM patients.
Conclusion: 6 weeks supplementation with selenium in patients with GDM can cause down regulated gene expression of TNF-α and TGF–β, and up regulated gene expression of VEGF. Selenium supplement had not any effect on gene expression of IL-1 β and IL-8.
