  • This review describes the wide spectrum of paroxysmal events during sleep in infancy and childhood. The differential diagnosis between sleep-related non-epileptic paroxysmal events and epileptic seizures is difficult in special occasions. The nocturnal frontal lobe seizure and of the more common nonepileptic paroxysmal events during sleep are described. The main differentiating features characterizing parasomnias are: onset in early childhood, rare episodes of long duration, relatively lower frequency per night, absence of stereotypy, gradual disappearance of older age. Video-polysomnography is the gold standard to diagnosing and differentiating parasomnias from nocturnal frontal lobe seizures.

  • Adding to the complexity of caring for critically ill patients is the fact that many of them have a creatinine clearance that exceeds $130mL/min/1.73m^2$. This phenomenon, termed augmented renal clearance (ARC), has only recently been widely recognized and its pathogenesis remains incompletely understood. However, ARC has been shown to result in increased dose requirements for drugs that are primarily eliminated by renal excretion, including many antimicrobial agents and enoxaparin. Recognition of ARC is hampered by the fact that the standard creatinine-based equations used to estimate renal function are not accurate in this clinical setting and the diagnosis is best established using both serum and urine creatinine measurements to calculate clearance. So a high index of clinical suspicion and awareness is usually required before this step is taken to confirm the diagnosis of ARC.

  • A simple and sensitive microplate enzyme immunoassay(ELISA) was developed for progesterone, based on progesterone monoclonal antibody as anti-progesterone, horseradish peroxise(HRP) as enzyme-label and tetramethylbenzidine(TMB) as substrate. The assay has a sensitivity of 5pg-120pg/well and intra- and inter assay coefficients of variation for progesterone standard curve(0.1ng-3.2ng/ml) were ranged 4.4-10.6% and 5.-12.6%, respectively. They assay is performed in less than two hours and provide reliable values to differentiate among samples from day 0(A.I.), day 14 and day 19. The discriminatory levels for early pregnancy diagnosis are [>10ng(day 19) & decreasing rate <1.5 : pregnancy] and [ 7ng & decreasing rate 1.5 : non-pregnancy]. The accuracy of the pregnancy diagnosis for cows classified as positive(pregnancy) and negative(non-pregnancy) were 96% and 100%, respectively.

  • Hypersensitivity Pneumonitis (HP) one of the most common interstitial lung diseases (ILDs) is characterized by exposure to an inhaled inciting antigen that leads to a host immunologic reaction determining interstitial inflammation and architectural distortion. The underlying pathogenetic mechanisms are unclear. The absence of international shared diagnostic guidelines and the lack of a "gold-standard" test for HP combined with the presence of several clinical and radiologic overlapping features makes it particularly challenging to differentiate HP from other ILDs, also in expert contests. Radiology is playing a more crucial role in this process; recently the headcheese sign was recognized as a more specific for chronic-HP than the extensive mosaic attenuation. Several classification proposals and diagnostic models have been advanced by different groups, with no prospective validation. Therapeutic options for HP have been limited to antigen avoidance and immunosuppressant drugs over the last decades. Several questions about this condition remain unanswered and there is a need for more studies.

  • In this study, statistical and neural network methods were used to recognize the cutting tool states. This system employed the tool dynamometer and cutting force signals which are processed from the tool dynamometer sensor using linear discriminent function. To learn the necessary input/output mapping for turning operation diagnosis, the weights and thresholds of the neural network were adjusted according to the error back propagation method during off-line training. The cutting conditions, cutting force ratios and statistical values(standard deviation, coefficient of variation) attained from the cutting force signals were used as the inputs to the neural network. Through the suggested neural network a cutting tool states may be successfully diagnosed.

  • For af accurate diagnosis and treatment planning of facial asymmetry, the use of 3-dimensional (3-D) image is indispensable. The purpose of this study was to get standard data for the 3-D analysis of facial asymmetry Computerized tomography (CT) was taken in the 60 normal occlusion individuals (30 male. 30 female) who did not have any apparent facial asymmetry. The acquired 2D CT DICOM data were input on a computer, and the reformatted 3-D images were created using a 3-D image software. Twenty three measurements were established in order to evaluate asymmetry; 15 ;omear measurements (6 for ramus length. 1 for condylar neck length, and 8 for mandibular body length) and 8 angular measurements (4 for gonial angle. 2 for frontal ramal inclination. and 2 for lateral ramal inclination) The right aid left difference of each measurement was calculated and analyzed. It is suggested that the right and left differences of the measurements obtained from the study could be used as references for the diagnosis of facial asymmetric patients.

  • Background: Colorectal cancer (CRC) is the fourth most common cause of cancer death in the world. Genetic variants in 8q24.21 including rs10505477 and rs6983267 have been hypothesized to be involved in susceptibility to CRC. This study aims to investigate the possible association between these loci and their haplotypes with CRC risk in Iranian population. Materials and Methods: Subjects were recruited from two hospitals in Tehran. The rs10505477 and rs6983267 polymorphisms were genotyped by TaqMan real time PCR using subject genomic DNA, extracted either from formalin-fixed, paraffin-embedded tissue of patients or from blood of the controls by standard methods. Results: A total of 715 subjects (380 CRC patients and 335 matched controls) were genotyped in this study. Allele and genotype analysis of the rs10505477 and rs6983267 polymorphisms by gender, age at diagnosis, tumor location, tumor grade, and tumor node metastasis (TNM) showed no significant association with CRC risk. There was a significant relationship between GG haplotype and susceptibility to age at diagnosis for both <60 and ${\geq}60$ (p=0.0005 and p=0.000004, respectively) and between GT and CRC in the age at diagnosis ${\geq}60$ (Table 3: p=0.031). The GG haplotype was less frequent in CRC patients with the age at diagnosis <60, but was more common in subjects with the age at diagnosis ${\geq}60$. Conclusions: Results of this study suggests that the rs6983267 and rs10505477 polymorphisms alone may not be relevant to CRC risk, but their GG haplotype plays a notable role in age at diagnosis of CRC in the Iranian population.

  • Purpose: To retrospectively determine whether specialized magnetic resonance imaging (MRI) reading performed by an experienced radiologist affected the successful assessment of extraprostatic extension (EPE) in the presence of biopsy-related hemorrhage after prostate biopsy. Materials and Methods: Two hundred consecutive patients with biopsy-proven prostate cancer underwent MRI. General radiologist and subspecialized radiologist readings were unpaired and reviewed in random order by a radiologist who was blinded to patients' clinical details and histopathologic data. The extent of hemorrhage was assessed on T1-weighted (T1W) MRI using a 1-4 scale, and the likelihood of EPE was assessed for each of the four categories. Histopathologic specimens served as the reference standard. The area under the curve (AUC) of the standard reading was compared to that of the specialized reading. Results: Post-biopsy hemorrhage was subjectively graded as ≥ 3 in 101 patients (50.5%) by standard reading, and in 100 patients (50.0%) by specialized reading. The standard and specialized readings disagreed for 40 (20.7%) of the patients (kappa [κ] = 0.35; 95% CI, 0.14-0.48). Of these, specialized reading was the correct interpretation for 21 patients (52.5%). The sensitivity (75% vs. 44%; P = 0.002) and area under the receiver operating characteristics (AUROC) (0.83 vs. 0.67; P = 0.008) of the specialized readings were significantly higher than those of the standard readings, while there was no significant difference in specificity (84% vs. 87%; P = 0.434). Conclusion: The reinterpretation of MRI by experienced radiologists significantly improves the diagnosis of EPE in prostate cancer in the presence of post-biopsy hemorrhage.
