BACKGROUND: Lovastatin has a unique ability to bind Leukocyte Function Antigen-1 (LFA-1), an integrin necessary for the full expression of inflammatory cytokines induced by the low molecular weight form of the extracellular matrix glycosaminoglycan hyaluronan (LMW HA). We hypothesized that lovastatin could inhibit LMW HA inflammatory signals via interaction with LFA-1, and attenuate bleomycin induced pulmonary fibrosis. METHODS: We evaluated the effects of lovastatin, pravastatin, LFA-1 blocking antibodies, and a novel LFA-1 inhibitor LFA 878 on LMW HA induced cytokine production in alveolar macrophages. We evaluated the effect of lovastatin in a bleomycin model of lung injury. RESULTS: Lovastatin immediately inhibited the LMW HA induced cytokine MIP 1-α (p=0.001) independent of HMG CoA reductase. Pravastatin showed no inhibitory profile when administered simultaneously with LMW HA. LFA-1 blocking antibodies and the small molecule statin derivative LFA 878 showed an inhibitory profile similar to lovastatin. Lovastatin showed decreased fibrosis on histopathology and improved survival at day 14, with a decrease in fibrocytes noted at day 8. CONCLUSION: Lovastatin and LFA 878 inhibit LMW HA inflammatory signaling independent of HMG-CoA decreasing the chemotactic cytokine MIP 1-α. Lovastatin treatment improves survival in bleomycin lung injury with decreased fibrocytes and fibrosis.

Vulval fibroadenoma is rare benign tumours arising from ectopic breast tissue or mammary like anogenital glands tissue. Only a few cases are reported in medical literature. It is usually seen between 20 - 80 years of age. Excision usually has good prognosis and rarely recurs. We present two cases of vulval fibroadenoma, one in a 26 years woman as a well defined soft tissue mass in right labia major and other in a 45 years woman as a pedunculated soft tissue mass in left labia major.

OBJECTIVE: To compare the technical quality of root canal obturation in relation to rotary and manual root canal preparation techniques. STUDY DESIGN: Cross sectional, analytical study. PLACE AND DURATION OF STUDY: The Aga Khan University Hospital Karachi from January till December 2011. METHODOLOGY: Data was retrospectively retrieved by periapical radiographs of 60 root canal treated molars for assessment of obturation quality. Data was divided into two groups, 30 radiographs in each group. Group 1 and 2 teeth were prepared with rotary and manual canal preparation technique respectively followed by obturartion with cold lateral condensation technique. Postobturation radiographs were assessed to evaluate technical quality of obturation in term of length, density and taper of root filling. Mann Whitney-U and Chi- square test was applied to compare the difference in technical quality of obturation between two canal preparation techniques. RESULTS: Amongst Thirty molar prepared with rotary instruments, 27 had achieved acceptable length, 25 had adequate density and 27 had achieved adequate taper. Amongst 30 molars prepared manually, 18 had achieved acceptable length, 14 had adequate density and 12 had adequate taper. CONCLUSION: Radiographic technical quality of the obturation (length, density and taper) was better with rotary technique as compared to manual canal preparation technique.

AIM: In this study we aim to determine the frequency of Inlet Patch (IP) and its association to clinical symptoms and draw attention to be aware of this heterotopic gastric mucosa. METHODS: This study was a prospective case series that IP was detected in the upper gastrointestinal endoscopy. Patients with laringopharyngeal reflux symptoms underwent endoscopy between March 2009 and July 2012 in two different institutions. All the biopsies were obtained from if there is the IP lesion and antral or/and gastric mucosa. The data was prospectively evaluated. The prevalence was compared with those of patients that did not determine IP in the study period. RESULTS: 3907 upper gastrointestinal system endoscopy was performed while 123 patients consist of 51 male and 72 female was determined as IP. The prevalence of IP in patiens who underwent upper gastrointestinal endoscopy was 3.14% in our study. The majority of symptoms of those who had IP were laringopharyngeal reflux symptoms. Heterotopic gastric mucosa was fixed in 114 cases while 28 chronic inflammation, 9 esophagitis, 5 intestinal metaplasia, 4 glicogenic acanthosis were obtained as additional findings in pathological examinations. CONCLUSION: Heterotopic gastric mucosa in the proximal esophagus is a frequent finding if the endoscopist is aware of this entity. The importance of IP is the increasing number of cases of neoplastic transformation. Symptomatic patients should be treated and should be considered of the complications of heterotopic gastric mucosa.

INTRODUCTION: Coronary Artery Disease (CAD) appears to be common in the Indian population of different geographical origins, religions and languages. Measurement of lipid fractions and ratios are widely recommended for risk assessment. A few studies have shown that serum uric acid plays a role in the development of cardiovascular morbidity. Very few reports are cited linking serum uric acid with the lipid fraction in CAD. OBJECTIVES: To find the significance of non-HDL cholesterol, LDL-c/HDL-c ratio, TC/HDL ratio and serum uric acid level in CAD patients. SUBJECTS AND METHODOLOGY: In this study, we included fifty CAD patients as subjects and an equal number of controls. Both subjects and controls were assessed for anthropometric, physiological and biochemical parameters. RESULTS: The present study showed significant increased levels of total cholesterol (p=0.002), TAGs (p<0.001), HDL (p=0.005), LDL (p<0.006) and non-HDL cholesterol (p<0.001). LDL-c/HDL-c ratio (p<0.001) and TC/HDL ratio (p<0.001) in CAD patients (subjects) were also significant when compared to controls. Uric acid level in CAD patients was increased (p<0.001). CONCLUSION: Serum Uric Acid, TC/HDL and LDL/HDL ratios could be regarded as objective markers, in association with existing atherogenic dyslipidemia in patients with CAD.

The Incidence of childhood obesity and metabolic syndrome is increasing even in rural and semi-urban regions of India. Adipose tissue mass secretes several inflammatory proteins, which could potentially alter the metabolic processes, leading to several complications at the later stages of life. With limited studies on protein bound sialic acid (PBSA) as a marker of oxidative stress mediated inflammation in obese children, this study was aimed to assess and correlate PBSA with lipid peroxidation and other cardiometabolic risk factors like Insulin Resistance (IR), serum magnesium, and high sensitive C reactive Protein (hsCRP) levels in order to provide an insight into the degree of systemic inflammation and oxidative stress. This study included 62 obese children (≥95% percentile of the CDC chart) and 60 non obese controls. This study documents significant higher levels of PBSA, IR, Malondialdehyde (MDA), hsCRP and uric acid in obese children (p<0.001). PBSA was associated with IR, hsCRP, uric acid, hypomagnesaemia. Higher degrees of oxidative stress, Insulin resistance and low serum magnesium levels were noted in obese children. PBSA and hsCRP levels were elevated and were associated with Insulin resistance in obese children of South Indian population.

AIMS: There is a cultural barrier to early medical intervention for diabetic foot infections in Trinidad & Tobago, stemming from the strong cultural belief in "soft candle" as effective treatment. We carried out a case-control study to evaluate the outcomes of "soft candle" to treat diabetic foot infections. METHODS: ALL CONSECUTIVE PATIENTS ADMITTED WITH DIABETIC FOOT INFECTIONS WERE INTERVIEWED TO COLLECT DATA ON: demographics, medical history, unhealthy lifestyle markers (exposure to risk factors for chronic diseases), chosen treatment and details of "soft candle" use. The hospital records were accessed on discharge to records the main outcome measures: HbA1c readings, duration of hospitalization, amputation and in-hospital mortality. Two groups were defined: The control group included patients who sought medical attention after detecting a foot infection. The study group included patients who recognized their infection but voluntarily chose to utilize "soft candle" regimens. We excluded patients who voluntarily chose to use other forms of non-traditional treatment or sought no treatment at all. Outcomes were compared using SPSS ver 19. A two-tailed P value was calculated for variables of interest in each group using Fisher's exact test. The duration of hospitalization between the groups was compared using paired T-Test. A P value <0.05 was considered statistically significant. RESULTS: There were 442 patients who met inclusion criteria: There were 60 patients in the study group at an average age of 55.2 years (SD ± 11.4; range 43-88): 63% had HBA1c readings >7.0% at presentation and 95% had unhealthy lifestyle habits. There were 382 patients in the control group at an average age of 59.1 years (SD ± 12.6, Range 37-89): 74% with HBA1c readings >7.0% at presentation and 48% with unhealthy lifestyle habits. Patients who used "soft candle" had significantly longer duration of hospitalization (15.5 ± 10.2 vs 9.2 ± 3.9 days; P<0.001) and major amputations (13.3% vs 5.6%; P=0.048) that was considered clinically significant. There was no difference in minor amputations (31.7% vs 34.3%; P=0.770) or in-hospital mortality (1.7% vs 0.52%; P=0.355) between the groups. CONCLUSION: In its current form, the traditional practice of topical "soft candle" application to diabetic foot wounds may be potentially harmful. Persons with diabetes should be warned about these effects. We have identified the target population for educational campaigns.

Residents' competency-based training and multidisciplinary cooperation are needed for rapid sequence spinal anaesthesia for fetal distress. Multiple standard but 'crash' spinal anaesthesia for non-obstetric procedures is imperative for acquisition of experienced hands. The purpose of this review is to share our modest experiences in the use of rapid spinal anaesthesia for emergency Caesarean delivery in pregnant women complicated with fetal distress. Fetal distress diagnosis is made promtly, intravenous line put in place in labour ward. Pre-loading or not, one-touch, non-touch spinal technique prevents unnecessary delay and further fetal hypoxic injury. Spinal pack is on stand by in the operating room at all time. Preloading is possible during the waiting period for other care providers otherwise coloading is used. A single wipe of the back with chlorhexidine lotion is frequently used for scrubbing. Lidocaine infiltration or spay is essential and does not waste time but opioid as adjuvant to bupivacaine wastes a lot of time to constitute and measure. So, opioid should be avoided. Average of 2.5 ml of 0.5% hyperbaric bupivacaine is frequently used in our centres. Surgery starts almost immediately after cleaning and drapping of the patient by the obstetrician. Ephedrine is made handy and constituted in case there is hypotension which fluid alone cannot treat.

Na(+)/K(+) pump or sodium- and potassium-activated adenosine 5'-triphosphatase (Na(+), K(+)-ATPase), its enzymatic version, is a crucial protein responsible for the electrochemical gradient across the cell membranes. It is an ion transporter, which in addition to exchange cations, is the ligand for cardenolides. This enzyme regulates the entry of K(+) with the exit of Na(+) from cells, being the responsible for Na(+)/K(+) equilibrium maintenance through neuronal membranes. This transport system couples the hydrolysis of one molecule of ATP to exchange three sodium ions for two potassium ions, thus maintaining the normal gradient of these cations in animal cells. Oxidative metabolism is very active in brain, where large amounts of chemical energy as ATP molecules are consumed, mostly required for the maintenance of the ionic gradients that underlie resting and action potentials which are involved in nerve impulse propagation, neurotransmitter release and cation homeostasis. Protein phosphorylation is a key process in biological regulation. At nervous system level, protein phosphorylation is the major molecular mechanism through which the function of neural proteins is modulted in response to extracellular signals, including the response to neurotransmitter stimuli. It is the major mechanism of neural plasticity, including memory processing. The phosphorylation of Na(+), K(+)-ATPase catalytic subunit inhibits enzyme activity whereas the inhibition of protein kinase C restores the enzyme activity. The dephosphorylation of neuronal Na(+), K(+)-ATPase is mediated by calcineurin, a serine / threonine phosphatase. The latter enzyme is involved in a wide range of cellular responses to Ca(2+) mobilizing signals, in the regulation of neuronal excitability by controlling the activity of ion channels, in the release of neurotransmitters and hormones, as well as in synaptic plasticity and gene transcription. In the present article evidence showing Na(+), K(+)-ATPase involvement in signaling pathways, enzyme changes in diverse neurological diseases as well as during aging, have been summarized. Issues refer mainly to Na(+), K(+)-ATPase studies in ischemia, brain injury, depression and mood disorders, mania, stress, Alzheimer´s disease, learning and memory, and neuronal hyperexcitability and epilepsy.

Advances in medical science procedures and their utilization in the field of oncology improved the survival of patients. In consequence, these advances have influenced the practice of physiotherapy. Physiotherapists utilize physical agents with the objective to enhance the health, welfare and quality of life and thus they can play important role in the management and rehabilitation of patients with prostate cancer (PCa). Urinary incontinence (UI) and erectile dysfunction (ED) are effects normally associated with the radical prostatectomy and radiotherapy due to the damage of the muscles of the pelvic floor (MPV). The aim of this work is to present findings related to the PCa and how the physiotherapist can guide the patient in relation to the knowledge and understanding of the anatomic structures related directly with the pelvic floor, the correct breathing and the perception of the MPV, as other muscles of the pelvis. Interventions of the physiotherapy will re-train the muscles of the pelvis by improving the active retention strength of the MPV in order to overcome the insufficiency (mainly the UI and ED) of the injured muscles. In conclusion, it is suggested to consider and to offer to the PCa patients the techniques related to the physiotherapy before and after the treatment.

Plumeria alba Linn (Apocynaceae) is used in Togolese traditional medicine to treat diabetes mellitus and wounds. The present investigation was carried out to evaluate the toxicity of hydroalcoholic extract of Plumeria alba roots in Sprague Dawley rats. The acute toxicity test was conducted by administering orally dose of 5 g/Kg. General behavior and mortality were examined for up to 14 days. The sub-acute toxicity test was performed by daily gavage at 250, 500 and 1000 mg/Kg for 28 days. Body weight and blood glucose were measured weekly. Hematological and biochemical parameters, relative organ weight were determined at the end of the 28 days administration. In acute study, no adverse effect of the extract was observed at 5.0 g/Kg. Sub-acute oral administration of the extract at the dose up to 1000 mg/Kg did not induce death or significant changes in body weight, relative weight of vital organs, hematological parameters and was not associated with liver and kidney toxicity.

BACKGROUND: Normal pregnancy has been associated with oxidative stress injury. Oxidative stress has been linked with poor perinatal outcome and birth asphyxia. The severity of this oxidative stress in newborn may be related to stress of different modes of delivery. METHODS: Eighty seven newborn babies were recruited in both labour ward and operating theatre of Ladoke Akintola University of Technology Teaching Hospital, Osogbo, Nigeria. Fourty one of them was delivered via spontaneous vertex delivery, 26 via emergency caesarean section and the rest, 20 were delivered through elective caesarean section. Cord blood sample was collected from new born babies immediately after delivery. Plasma was extracted and used for the laboratory measurement of total antioxidant status, malondialdehyde and Uric acid. RESULTS: There were no significant (P>0.05) changes among the studied groups in mean plasma levels of malondialdehyde, total antioxidant status and uric acid. However, a trend was observed in these parameters. Mean plasma total antioxidant status/mmol/l was observed to be highest in subjects delivered through ECS (2.35 ± 0.05) and lowest in subjects delivered through SVD (2.03 ± 0.08). Similarly mean plasma UA/mg/dl was also observed to be highest in subjects delivered through ECS (3.61 ± 0.16) lowest in those delivered through SVD (3.49 ± 0.71). The highest mean plasma level of MDA/µmol/l was found in subjects delivered through SVD (5.78 ± 1.56) while the lowest was found in subjects delivered through ECS (5.01 ± 1.21). CONCLUSION: There is no significant relationship between oxidative stress markers in neonate and the mode of delivery.

This study sought to investigate the protective effect of dietary inclusion of Hibiscus sabdariffa calyx red dye on cisplatin-induced nephrotoxicity and antioxidant status in rats. Adult male rats were randomly divided into four groups of six animals each. Groups I and II were fed basal diet while groups III and IV were fed diets containing 0.5% and 1% of the dye respectively for 20 days prior to cisplatin administration. Nephrotoxicity was induced by a single dose intraperitoneal administration of cisplatin (7 mg/kg b.w) and the experiment was terminated 3 days after. The kidney and plasma were studied for nephrotoxicity and oxidative stress indices. Cisplatin administration caused a significant (P<0.05) increase in creatinine, uric acid, urea, and blood urea nitrogen (BUN) levels as well as kidney malondialdehyde (MDA) content, with concomitant decrease in kidney vitamin C and GSH contents. Furthermore, activities of kidney antioxidant enzymes such as, SOD, Catalase, and GST were significantly (P<0.05) altered in cisplatin administered rats. However, consumption of diets supplemented with the dye for 20 days prior to cisplatin administration protected the kidney and attenuates oxidative stress through modulation of in vivo antioxidant status. The determined anthocyanin content of the dye is 121.5 mg Cyanidin-3-rutinoside equivalent/100 g, thus, the observed nephroprotective effect of H. sabdariffa dye could be attributed to its anthocyanin content.

BACKGROUND: We aim to evaluate the metabolic and inflammatory responses after ERCP procedure in patients who have common bile duct stones. METHODS: Between September 2009 and October 2010, we studied prospectively 50 patients who diagnosed with common bile duct stones. Our study was included patients who had previously been suspected with common biliary duct stone via radiological and biochemical examinations. We investigated parameters of pro-inflammatory cytokines (IL-1β, IL-6, Il-8, IL-12, IFN-γ, TNF-α), anti inflammatory cytokines (IL-4, IL-10, IL-13), stress hormones (ACTH, cortisol, growth hormone, aldosterone) and acute phase reactant (CRP). All venous blood samples were taken firstly 1hr before endoscopic intervention as a control. After ERCP procedure, venous blood samples were taken two more times, the first in 1hr, the second in 24 hours. RESULTS: We performed ERCP successfully to 50 patients due to common bile duct stones. All of them had higher serum cytokine levels (p<0.01) after an hour and 24 hours later ERCP than before endoscopic intervention except IL-13 level. A significant increase (p<0,01) was found in ACTH, cortisol, GH and aldosterone levels 1 hour and 24 hours after ERCP, except GH level (p>0.05). CRP level was significiantly increased 1 hour and 24 hours after ERCP. CONCLUSION: ERCP procedure is a kind of invasive attempt as known, also causes, with its effects, systemically inflammatory response in the body. This response, mostly not staying at the local stage, becomes systemic inflammatory response. Therefore, before ERCP is performed, the applications of other non-invasive methods of diagnosis are strongly advised.

The crown gall induced in potato discs by Agrobacterium tumefaciens is becoming largely utilised in screening anti-tumor agents. The present work is showing that beet discs are more adequate for the anti-tumor screening test. In fact, maximal tumor induction was observed on beet discs (87.5%), followed by carrot discs (75%) and potato discs (68.5%). Beet discs present the most sensibility to crown gall disease with a fast expression of symptoms and more visible galls without any staining need. The beet discs bioassay was carried out by using some synthesized organometallics known for their antitumor activity in mammalian cells. We found significant crown gall inhibition (20.7% to 40.55%) of the tested compounds. Overall results supported that beet bioassay might be a potential prescreen system of anti-tumor molecules in mammalian cells.

The seroepidemiology of Helicobacter pylori infection in pregnant women in Durango, Mexico is largely unknown. The prevalence of anti-H. pylori IgG antibodies was examined in 343 pregnant women living in rural areas in 7 municipalities in Durango State, Mexico, using enzyme-linked immunosorbent assays (ELISA). A correlation of H. pylori seropositivity with socio-demographic, obstetric and behavioral characteristics of pregnant women was also assessed. In total, 179 (52.2%) of the 343 pregnant women (mean age, 24.2 ± 5.9 years) had H. pylori IgG antibodies, 75 (41.9%) of whom had H. pylori IgG antibody levels higher than 100 U/mL. The seroprevalence of H. pylori infection varied from 33.3% to 65% among municipalities. In contrast, the seroprevalence was comparable among women regardless their age, educational level, occupation, socioeconomic status, animal contacts, foreign travel, eating habits, contact with soil, crowding, sanitary conditions at home and educational level of the head of their families. Multivariant analysis of socio-demographic and behavioral variables showed that H. pylori seropositivity was associated with municipality (OR=1.12; 95% CI: 1.01-1.24; P=0.02). Of the obstetric characteristics, the seroprevalence of H. pylori infection increased significantly with the number of pregnancies and deliveries but not with the number of cesarean sections or miscarriages. Rural pregnant women in Durango had a lower seroprevalence of H. pylori infection than those from populations in developing countries. Results support a variability of H. pylori seroprevalence within a region. Further research at a municipal level might help to understand the epidemiology of H. pylori infection.

Chronic inflammatory disorders have been associated with accelerated atherosclerosis and increased cardiovascular (CV) risk. Recent evidence suggests that erosive hand osteoarthritis (EOA) has considerable inflammation; therefore, we examined the presence of subclinical atherosclerosis and endothelial dysfunction in EOA. Twenty-four patients with EOA and 24 age- and sex-matched healthy individuals without clinical OA were included in the study. No subject had a history of CV disease. Intima-media thickness (IMT) and atheromatous plaques in the common carotid and common femoral arteries were measured by Doppler ultrasonography. The endothelium-dependent, flow-mediated dilatation (FMD) and endothelium-independent, sublingual glyceryl trinitrate (NTG)-induced dilatation (NMD) of the brachial artery were assessed. The EOA patients had significantly elevated systolic and diastolic blood pressure (p<0.001 for both). The 10-year risk of general CV disease, as predicted with the Framingham Risk Score, was similar in patients and controls (p=0.18). IMT of both common carotid and common femoral artery were increased in EOA (p=0.01 and p<0.01, respectively), but the frequency of atherosclerotic plaques was not increased. There was no difference in FMD and NMD between the two groups, but the difference between FMD and NMD was increased in EOA. In conclusion, this small controlled study showed an association between EOA and subclinical atherosclerosis that cannot be fully attributed to traditional CV risk factors, as assessed by the Framingham score. These results suggest that chronic, low-grade inflammation is implicated in atherosclerosis in EOA.

INTRODUCTION: The aim of this study was to compare two groups of patients with early stage cervical cancer who underwent either abdominal or vaginal surgery, in terms of post-operative findings and survival. MATERIALS AND METHODOLOGY: 55 patients with diagnosed cervical cancer were retrospectively selected for this study. They were preoperatively staged according to FIGO criteria. Forty four patients had disease between stages Ib and IIa with no evidence of extra-pelvic lymph node involvement and 10 patients had stage ≥ IIb. RESULTS: Of the 55 patients, 17 had been operated by Schauta-Amreich radical vaginal hysterectomy and 38 by Piver type II abdominal hysterectomy. No significant statistical differences have been found between two groups about age (median age was 49 for Schauta and 54 for Piver p=0.494) and parity of the patients (Median parity was 2 (range: 0-5) for Piver II group and 1 (range: 0-4) for Schauta group (p=0.607)) and about histotype and stage of the cervical cancer (34 patients with squamous cell carcinoma among Piver II Group vs 16 patients from Schauta Group; 4 women with adenocarcinoma from Piver II Group vs 1 subject from the Schauta Group; p value 1.000). Among the two groups there were significant statistical differences regarding the mean operative time (86 ± 28 minutes for Vaginal surgery and 115 ± 31 minutes for Abdominal surgery, p=0.038) and the average hospital stay (8.65 ± 4.42 days for abdominal surgery and 5.65 ± 2.3 days for vaginal surgery, p=0.020). Significant statistical difference was reported as regarding adjuvant RT, increased in the Piver II group with respect to the Schauta group (22 vs 4 pts; p=0.028). The survival rate at 5-years was without significant difference between the two groups (23 patients frof Piver II Group vs 11 patients from Schauta Group, p=0.510). DISCUSSION: This study confirms the benefits of the Schauta-Amreich vaginal radical hysterectomy in terms of hospital stay, mean operative time and early complications. CONCLUSION: We believe that this surgery is a plausible alternative to radical abdominal hysterectomy and could be considered to be a valid approach for the treatment of patients with cervical neoplasms, but still randomized trials are needed on this topic with respect to the ethical issues involved.

The most cost effective method of prevention and detection of cervical cancer is the Pap smear. In abnormal Pap smear, colposcopy, endocervical curettage and biopsy will be done. Gold standard method in detecting cervical lesion is biopsy. Now in two ways conventional Pap smear and liquid base are routine diagnostic technique in Iran and given easily and cost-effectiveness of this method in the detection of cervical lesions to determine the sensitivity the objective of this study was compare three methods of Pap smear and colposcopy in detection of any lesion to gold standard biopsy in the positive ASC cases who referred to gynecologic Oncology Clinic of shahid Sadoughi University of Medical Science. This study is a descriptive analytic in 2009-2010 years on 150 cases of patients with Atypical Squamose Cell (ASC) results in previous pap smear ,conventional pap smear, liquid based pap smear, colposcopy and cervical biopsy had been done for all patient and finally data were analyzed with chi-square statistical test on spss ver 16 saftware. Average age of patients in this study was, 42 ± 9.9 year and reason for referring patients in 35.4% of cases was due to follow-up of abnormal results of previous Pap smear, in 30% bleeding, 12% Pain and 2.6% percent of cases was checking-up. In final results of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy any of the methods conventional and liquid based Pap smear and colposcopy were compared with cervical biopsy as a gold standard. The conventional Pap smear method had a sensitivity 51%, specificity 66.6%, PPV 96%, NPV was 8% and accuracy was 92%, about the liquid base Pap smear method, sensitivity was 55.3%, specificity was 77.7%, PPV was 97.5%, NPV was 10% and accuracy was 56/6%. About the colposcopy, sensitivity was70/9 % specificity 44/4%, PPV was 95.2%, NPV was 8/8% and accuracy was 69.3%. The relationship between sensitivity results of conventional Pap smear and colposcopy, with p<0.001 and between the results of sensitivity of liquid based cytology and colposcopy with p<0.01 relationship was significant. Colposcopy has the best efficacy in detecting any cervical lesion in compared with any other diagnostic technique. so that further studies with more detailed plans and bigger sample sizes are suggested for obtaining reliable result.
