A study to evaluate a correlation between various Gray Scale parameters and period of gestation

Background: Accurate prediction of the gestational age (GA) is very important in the management of obstetric patients for planning a timely and uneventful outcome. Fetuses with intrauterine growth restriction (IUGR) are at high risk for poor short- and long-term outcome. The present study was conducted with the aim to evaluate a correlation between various Gray Scale parameters and period of gestation.Methods: A total of 100 clinically suspected FGR subjects were enrolled for the present study. Women with singleton pregnancies with fundal height being less than the period of gestation by 4 weeks or more and certainty of last menstrual period with previous 3 menstrual cycles were included in the present study. Ultrasound examination both by Gray Scale USG carried out serially every three weeks starting from 30 weeks till delivery. Chi-square test was used to compare the proportions while Independent Samples "t"-test was used to compare the parametric variables in two groups. Receiver-Operator curve analysis was performed to find out appropriate cut-off points for prediction of FGR.Results: Diagnostic accuracy of TCD/AC ratio as a marker of FGR was found to be 77%, of HC/AC ratio was found to be 93% and FL/AC ratio was 59%.Conclusions: Among three gray scale parameters being assessed, HC/AC ratio at 36 weeks was observed to be having 98.5% sensitivity and 82.9% specificity, thus showing the highest diagnostic accuracy (93%). However, from the point of view of early detection, TCD/AC ratio was found to be most efficient with 81.5% sensitivity and 68.6% specificity and overall diagnostic accuracy of 77%. Precision of Grayscale findings at later stage (36 weeks) are higher

A study on maxillary sinus dimensions by computed tomography in population of UTTARPRADESH

The maxillary sinuses are the largest of the paranasal air sinuses and are contained within the body of the maxilla one on each side. They are of the shape of an irregular three sided pyramid. The apex extends into the zygomatic process of the maxilla and the base is the lower part of the lateral wall of the nose

Case Report Bilateral Maxillary Sinus Hypoplasia

Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus hypoplasia, type 2 shows significant sinus hypoplasia with narrowed infundibular passage and hypoplastic or absent uncinate process, and type 3 is cleft like maxillary sinus hypoplasia with absent uncinate process. CT and endoscopic examination usually complement each other in diagnosing MSH

Role of color doppler in the diagnosis of intra uterine growth restriction (IUGR)

Background: The purpose of our study was to evaluate the diagnostic efficacy of the pulsatility index (PI) and resistive index (RI) in uterine artery, umbilical artery and middle cerebral artery in the diagnosis of IUGR and prediction of adverse perinatal outcome.Methods: A total of 100 clinically suspected IUGR cases were enrolled in the study. A detailed history and examination was done, color doppler carried out serially every three weeks starting from 30 weeks till delivery, subsequently confirmation of fetal growth restriction (FGR) was done by assessing the newborn parameters for growth restriction.Results: Doppler measurement for uterine artery showed higher efficacy as compared to umbilical artery and middle cerebral artery findings. The uterine artery RI was found to be 84.6% sensitive and 82.9% specific even at 30 weeks. Uterine artery PI too showed a good diagnostic efficacy with an accuracy of 79%, a sensitivity of 76.9%, a specificity of 82.9%.Both PI and RI for uterine artery showed a relatively higher specificity.Conclusion: Here we concluded that once IUGR is suspected, Doppler velocimetry may be useful as a part of evaluation and uterine artery analysis identifies a subgroup with an increased risk for developing IUGR.

Radiographic diagnosis of a rare case of oculo-dento-digital dysplasia

Oculodentodigital dysplasia (ODDD), also known as oculodento-osseous dysplasia, is an extremely rare autosomal dominant disorder with high penetrance, intra- and interfamilial phenotypic variability, and advanced paternal age in sporadic cases. The incidence of this disease is not precisely known, with only 243 cases reported in the scientific literature, suggesting an incidence of around 1 in 10 million people. It is marked mainly by eye abnormalities, craniofacial dysmorphism, dental anomalies, hand and foot malformations, various skeletal defects, and mildly delayed mental development. Neurological changes may appear earlier in each subsequent generation. This case report describes a radiological diagnosis of ODDD based on physical appearance, clinical features and radiographic findings in a 16-year-old girl

Emphysematous osteomyelitis: Report of two cases and review of literature

Emphysematous osteomyelitis is a rare condition characterized by the presence of intraosseous gas. A prompt diagnosis is required for this disease to expedite management as it is a potentially fatal condition. Many comorbidities, such as malignancy, diabetes mellitus, alcohol abuse, Crohn’s disease, and other etiologies causing immunosuppression, predispose to this condition. The causative organisms are generally anaerobes or members of Enterobacteriaceae family; however, the infection can be mono or polymicrobial. We report two cases affected with emphysematous osteomyelitis due to varied underlying comorbidities. The purpose of this study is to (a) emphasize the importance of computed tomography in diagnosing emphysematous osteomyelitis and (b) to highlight an unusual location of this rare pathology
