Evaluation of splenic enlargement is important in the diagnosis and management of various diseases including liver disease, lymphoma and other primary or metastatic neoplasm. This cross sectional study was conducted in the department of radiology and imaging in Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) from July 2007 to June 2009. The main objective of the study was to find out a more accurate sonographic measurement of splenic volume that well correlate with gold standard computed tomography (CT) volume. A total of 228 subjects were included in the study. All the subjects underwent ultrasound and CT examinations for measurement of splenic volume. The mean splenic volume measured by AVL (average length) was 182.62±80.28 cm3 (mean±SD) with range of 45.61-590.93 cm3 and by CT scan was 190.18±77.77 cm3 (mean±SD) with range of 46.52-565.81cm3. Most of the subjects 138(60.5%) had splenic volume 101-200 cm3. Splenic volume was evaluate by CT findings of 228 cases and expressed in cm3. Sonographic splenic volumes were calculated by using the prolate Ellipsoid method AVL (average length) and also expressed in cm3.The mean difference of splenic volume evaluated by CT and sonography was 7.43±5.39 cm3 with standard deviation of 5.39 cm3 measured from average length (AVL). The mean difference of splenic volume evaluated by two modalities measured by average length was statistically significant (pp<0.001).

Background: Decreased mouth-opening is a key factor in diagnosing most of the oralhealth- related conditions. Aim: To assess the Maximum Mouth Opening and its correlation with facial types among children in Southern Saudi Arabia. Method: A cross-sectional study was conducted among the patients ranging from 2 to 12 years old. The maximum mouth opening was measured as the distance between incisal edge of maxillary and mandibular central incisors in the midline using the digital Vernier Caliper. Three readings of maximum mouth opening (MMO) were taken by the examiner and the average mean of these readings was taken as final MMO. Based on the calculated facial index, five facial types were determined and subjects were categorized and compared accordingly. The facial profiles, height, weight and BMI (Body mass Index) of the subjects was recorded as well. The data hence obtained was subjected to statistical analysis using SPSS (version 19.0, SPSS Incorporated, Chicago, IL, USA). Results: It was found that the mean value of maximum mouth opening of Hyperleptoprosopic (? 95.0) children was significantly higher than other children. The mean difference of mouth opening of Mesoprosopic (85.0 - 89.9) children was significantly lower than Leptoprosopic (90.0-94.9) and Hyperleptoprosopic (? 95.0) children. The mean difference of mouth opening of Leptoprosopic (90.0-94.9) was significantly lower than Hyperleptoprosopic (? 95.0). Conclusion:The overall mean value of maximum mouth opening among the subjects was found to be 47.33? 8.7. The maximum mouth opening of subjects was found to have an association with different facial types and facial profiles among the studied population.

Background. The reliability of blood pressure (BP) measurement in hospitalized patients is a topic of debate and the therapeutic implication of the routinely collected BP profiles is probably overestimated. When measurements are performed in elderly patients, further potential sources of misinterpretation occur. Methods. We conducted a subanalysis of a previous study including 79 over 80-year-old hypertensive patients, hospitalized in an internal medicine ward. Five modalities of BP evaluations (measurement by physicians and nurses, self-measurement by patients, Finometer® beat-to-beat finger monitoring, and 24h monitoring) were analyzed, considering agreement and accuracy. Results. The mean (SD) age of the patients was 86.9±4.9 years (50% women). Patients’ self-measurements of both systolic and diastolic BP (SBP and DBP) did not differ significantly from daytime 24-hour monitoring (D24hBPM) (mean difference -1.52, SE 1.71; p: ns and -0.58, SE 1.19 mmHg; p: ns). Conversely, SBP and DBP registered by nurses did significantly differ (mean difference -7.34, SE 1.42; p=0.007 and -4.7, SE 1.05 mmHg; p=0.003). SBP and DBP measured by patients also showed the better concordance, with lowest biases, and narrowest limits of agreements (LoA) and for SBP higher Kappa statistic values (bias 1.5, LoA -28.9 to 31.9; κ 0.563 and bias 0.6, LoA -20.4 to 21.5 mmHg; κ 0.412). The patients’ sensitivity and specificity in predicting hypertensive systolic D24hBPM were 84.8% and 69.7%, respectively. Conclusions. In elderly hospitalized patients an alternative to 24hBPM, self-measurements by patients offer the better agreement and reliability in detecting hypertensive values.

Aims: To determine the reliability of transpalpebral ultrasound in B-mode (B-TUS) with a high-resolution linear probe (18 MHz) in estimating both the ocular anterior chamber depth (ACD) and axial length (AL), as well as its agreement with the IOL Master 500 optical biometer. Material and methods: Cross-sectional study on 82 eyes of 41 volunteers with no history of eye disease. ACD and AL were determined using B-TUS and the IOL Master 500. The agreement between the two tech-niques and the variability of B-TUS (inter- and intra-observer) were analyzed with the Bland-Altman method. To this end, the mean difference between measures±1.96 SD was calculated to determine the limits of agreement (LoA). Results: The mean difference±1.96SD between B-TUS and the IOL Master 500 was -0.41±0.25mm for ACD (p<0.001) and -0.48±0.45 mm for AL (p<0.001). The maximum variability for B-TUS (average±1.96SD) was 0.00±0.35 mm at the inter-observer level for AL, and 0.00±0.18mm at the intra-observer level for AL. Conclusion: The determination of ACD and AL by B-TUS has a good re-liability and variability, in line with other sonographic techniques. However, it systematically provides smaller measurements than those obtained with the IOL Master 500, similar to the conventional ultrasound techniques. B-TUS could be useful in the assessment and follow-up of a wide range of ophthalmic diseases, in which a high accuracy in ACD and AL is not determinant.

Background: One of the basic steps to quality improvement in hospitals is to obtain patients’ feedback. Objectives: The aim of this study was to assess the quality of hospital services from patient’s perspective in hospitals affiliated with the Dezful University of Medical Sciences (DUMS), Dezful, Iran. Methods: In this cross-sectional study, 400 patients were selected from six hospitals of DUMS. The data was collected using the SERVQUAL questionnaire including 22 pairs of questions (organized in two aspects of service importance and performance) in 5 dimensions of tangibility, reliability, responsiveness, assurance and empathy. The importance-performance analysis (IPA) was used to determine the weaknesses of service quality and prioritizing the aspects requiring improvement. Results: The mean age of the patients was 38.5, 32% (n = 128) had academic degrees, 55% (n = 220) were self-employed, and 16.5% (n = 66) did not have health insurance. The average length of day was 7.8 ± 8.3 days. The mean score of the importance and performance were 4.37 ± 0.75 and 3.72 ± 0.94, respectively. The service quality gap was -0.65. Tangibility (-0.68) had the largest negative gap while the smallest gap was related to the reliability (-0.63). The gap between importance and performance was significantly negative in all attributes and dimensions (P < 0.001). The results of the IPA showed that the tangibility was located in the Q VI, reliability and assurance in the Q I, and the responsiveness and empathy in the Q III quadrants. Conclusions: Quality of hospital services did not meet patients’ expectations and there is a room for improvement and obviate the gaps. Decision-makers can further use the results of the IPA to effectively allocate limited resources giving special attentions to the organizational weaknesses.

ABSTRACT Aim: The aim of our study was to do an agreement analysis of two different laboratory methods used to measure electrolytes i.e., between the ISE based Beckman Coulter Synchron CX9 PRO Biochemistry analyzer and RAL′s Ion3 Flame Photometer (Técnica para el Laboratorio, Barcelona, Spain), in serum samples. Materials and Methods: This cross sectional study was done over a period of three months from September′09 through December′09 on routine biochemistry samples. A total of 6492 samples were received for routine biochemistry analysis from those 630 blood samples were randomly processed for this study. Two ml of sample was taken in a plain gel tube (LABTECH Disposables, Ahmedabad, India), centrifuged and further processed using both systems within one hour of the sampling to obtain the Na and K concentrations in the samples. The bias and variability of differences in measured values were analyzed according to Bland and Altman method. Results: Flame photometry method has drawbacks such as low throughput, requires manual operation, is a time consuming procedure. Ion selective electrodes technique is a more universal method for the high throughput determination of electrolytes in physiological samples; Beckman Coulter Synchron CX9 PRO is an example of such a system. The mean difference between the two methods (standard minus test) and 95% limits of agreement for sodium in serum was -7.8±17.3 (-42.2 to 26.6) and in urine was -22±41 (-104 to 60). Similarly, the mean difference between the two methods for potassium values in serum was found to be -0.25±0.75 (-1.75 to 1.25) and in urine was -5.3±38.9 (-83.1 to 72.5). With 95% confidence interval, the value of sodium and potassium as determined by both the methods lie between the upper and lower limit showing 95% limits of agreement. Conclusion: Good degree of agreement was seen on comparing the two methods for measuring the electrolytes; the use of Synchron CX9 in place of Flame photometer for electrolyte analysis in serum and urine is justified or use the two interchangeably.

Background: The amniotic fluid is fundamental for proper fetal development and growth. Ultrasound visualization of the amniotic fluid permits both subjective and objective estimates of the amniotic fluid. Objective: The objective of this study was to determine the reference values of normal single deepest pocket (SDP) – upper and lower limits, mean SDP and variation of the SDP with gestational age among Igbo women of South-Eastern Nigeria extraction carrying uncomplicated singleton pregnancy. Methodology: This was a prospective cross sectional study involving 400 women carrying uncomplicated singleton pregnancies and who were sure of the date of the first day of their last menstrual period. The single deepest pocket / maximum vertical pool were determined once at presentation at the hospital.. The study was conducted from January 1st to December 31st 2015. The second author carried out all the scanning. The SDP was obtained. Results: The womens’ mean and median ages were the same at 28 years. The gestational age range of the pregnancies was 14-41 weeks. The mean SDP was 5.8cm, while the 5th and 95th percentiles were 3.3cm and 8.5cm respectively. There was no difference in the mean SDP in both term and preterm. There was irregular but continuous rise of mean SDP to a peak of 6.8cm at gestational age of 39 weeks. In conclusion, the participants had a mean SDP of 5.8cm. There was also a positive correlation between SDP and Gestational age. We therefore recommend a longitudinal study to assess perinatal outcome and abnormal amniotic fluid volume among Igbo women of South-Eastern Nigeria. Key words: Single Deepest Pocket, Uncomplicated Singleton Pregnancy, Igbo Women.

Endoscopic Tympanoplasty

Tympanoplasty is one of the most performed procedures in ENT. The aggressiveness of its microscopic approach has led otologists to adopt the endoscopic approach as a less invasive alternative. The purpose of this work is to appreciate the advantages and disadvantages of this surgical technique. We conducted a prospective descriptive cross-sectional study on 20 interventions within the ENT department of August the 20th 1953 Hospital of Casablanca from April 2019 to June 2019. The average age of operated patients was 36.3 years. Perforations were unilateral in (71%) of the cases with a predominance of the anterior (29%) and subtotal (36%) locations. The tympanoplasties were performed by 3 different senior otologic surgeons, and were left in (57%). The mean operating time was (59.5 min) and the mean anesthesia duration was 75.1 min. Intraoperative vision allowed us to fully visualize the margins of all perforations (100%) and anatomical structures of the middle ear in almost all interventions. The first procedures carried out were filled with difficulties whose management of intraoperative bleeding was the main one in (42.8%) of the cases. (57%) procedures were described as easy. No complication was detected intraoperatively or immediately postoperatively. Endoscopic tympanoplasty has several advantages, including: Minimally invasive approach to the middle ear; panoramic perioperative vision; Gain of operating time; decrease in the duration of anesthesia; Valuable educational tool; postoperative comfort; Decrease in hospital stay and early return to daily activities; Better aesthetic rendering; cost and transportability. However, we also note a number of disadvantages of endoscopic tympanoplasty, particularly: performing the procedure with one hand; difficulty passing through the EAC; 2D vision that alters the perception of depth; management of intraoperative bleeding; fogging; learning curve.
