<p>Abstract:</p><p><strong>Background</strong>: Hearing  plays  a  valid  role  in  speech  development  in  children. Otitis media with effusion is one among the commonest causes of hearing loss in children especially below 12 years. It is defined as the presence of fluid in the middle ear without signs or symptoms of acute ear infection</p><p><strong>Methods</strong>: A prospective study was carried out in Lourdes Hospital, Kochi, over a period of 1 year from January 2013 to December 2013. Thirty patients with chronic middle ear effusion  below the age of 12 years were selected for the study.</p><p><strong>Results</strong>: of the 30 patients  59.5% of patients were in the age group of 5-7 years of age, 16.6 % of patients were in the age group of 9-11 years of age .13.3%  of patients  each were in  the age group of 3-5 years and 7-9 years of age.Among  the 30 patients ,60% were male children and 40% patients were female children.Among the 30 patients , 40% of them had grade 3 adenoid hypertrophy ,33.3% of them had grade 2 adenoid  hypertrophy and  30% of them had grade 4 adenoid hypertrophy and none had grade 1 adenoids. majority of them had grade 3 adenoid hypertrophy by endoscopic assessment.Among  the 30 patients ,66.6 % of them had eustachian tube blockade by the adenoid mass and  33.4% of  them didn’t have eustachian tube blockade.  100% of them  with eustachian tube blockade found to have fluid on doing myringotomy  and  there was  20% of chance of absence of  fluid ,if there is absence of  eustachian tube blockade.</p><p>            Significant association was found between  type B tympanogram and presence of fluid on myringotomy .92.5% of patients with type B tympanogram had fluid on myringotomy . 57.1 % of patients with type C tympanogram  had fluid on doing myringotomy.There were 2 patients with grade 4 adenoid hypertrophy ,without eustachian tube blockade with  bilateral type C tympanogram and  there  was  bilateral dry tap on myringotomy. This reveals that type B tympanogram  and  eustachian tube blockade  better predictor of  otitis media with effusion   than grade of adenoid hypertrophy.</p><p><strong>Conclusion:</strong></p><p>    The present  study  showed that  chronic middle ear effusion was found to be most common  in the age group of  3-5  years of age group and  relatively common in the male children. Tympanogram type B was found to be  strongly associated with fluid on myringotomy .All the children with chronic middle ear effusion in the study group were found to have  ,grade 3 grade 2,and grade 4  adenoid hypertrophy in the  descending order of frequency.Grade 3 adenoid hypertrophy was present in majority of  the children in the study group .Lateral  adenoid hypertrophy ,abutting on the nasopharyngeal orifice of Eustachian tube was present in majority of children.

Surgical treatment results for 135 patients with proximal humerus injuries are presented. According to AO classification type A fractures were diagnosed in 86 (63.7%), type B — in 44 (32.5%) and type C — in 5 (3.8%) patients. In 53 (39.3%) patients osteosynthesis with devices elaborated at clinic were used. Treatment results showed that in young and middle aged patients with good bone tissue quality with type A fractures T- and L-shaped fixatives and elaborated at clinic device that provided interfragmental compression should be used. In patients with type B fractures and low bone density either sparing synthesis by Weber — Muller or elaborated at clinic device with blocking screws and in patients with type C fractures — either synthesis with pins or primary shoulder arthroplasty were recommended.

Abstract Contact of facades with degradation agents and direct incidence of ultraviolet radiation on external coatings make them more opaque over time, affecting their colour and reflectance characteristics. This study evaluated the effect of adding different TiO2 contents to mortars applied in concrete substrates in order to verify the reflectance maintenance on surfaces after exposure over time. Mortar with different concentrations of TiO2 (1%, 5%, 10%) were produced in relation to the total dry premix, added as a powder and compared to unpainted mortar without TiO2 (type "A") and painted mortar without TiO2 (type "B"), both used as a reference for colour and reflectance. Exposed over 16 months to climate conditions in São Paulo, regarding the maintenance of reflectance and solar radiation, the results showed that type "B" (0%TiO2) painted mortar presented the best performance. Type "C" (1%TiO2) and type "D" (5%TiO2) unpainted mortar remained more stable. Type "A" (0%TiO2) and type "E" (10%TiO2) unpainted mortar showed greater differences according to the Just Noticeable Difference (JND) range caused by dirt pick up.

Fifteen linguistically normal children and 15 linguistically deviant children were presented with three types of agrammatical sentences. The subjects were asked to judge the sentences as right or wrong and to change the sentences judged as wrong, rendering them correct. The three types of agrammatical sentences represented rule violations of syntactic agreement (Type A), lexical restrictions (Type B), and word order (Type C). The two groups of children were compared in terms of the number of sentences of each type that were recognized as agrammatical. Those productions which represented the child’s correction of agrammatical sentences were subjected to descriptive analyses (percentages) with specific reference to the number of attempted changes and the number of those changes which demonstrated corrections of the specific deviation from well formedness. Results indicated that the two groups of subjects were significantly different in their ability to recognize grammatical errors in sentence Types A and C, but did not differ in their ability to recognize errors in sentence Type B. The descriptive comparison of the groups' verbal corrections reflected this trend, in that the language-disordered subjects made corrections specific to the error on more of the Type B sentences (for example, “The dog writes the food.”) than on Types A (for example, “'She will pick some flowers last week.”) or C (for example, “Get and come your dinner.”). Linguistically normal children accurately corrected 90.7% of the sentences judged as agrammatical; this percentage did not vary more than 1% across sentence types.

To better understand the structural characteristic of adsorption pores (pore diameter < 100 nm) of coal reservoirs around the coalbed methane production areas of western Yunnan and eastern Guizhou, we analyzed the structural and fractal characteristics of pore size range of 0.40–2.0 nm and 2–100 nm in middle–high rank coals ( Ro,max = 0.93–3.20%) by combining low-temperature N2/CO2 adsorption tests and surface/volume fractal theory. The results show that the coal reservoirs can be divided into three categories: type A ( Ro,max < 2.15%), type B (2.15% <  Ro,max <2.50%), and type C ( Ro,max > 2.15%). The structural parameters of pores in the range from 2 to 100 nm are influenced by the degree of coal metamorphism and the compositional parameters (e.g., ash and volatile matter). The dominant diameters of the specific surface areas are 10–50 nm, 2–50 nm, and 2–10 nm, respectively. The pores in the range from <2 nm provide the largest proportion of total specific surface area (97.22%–99.96%) of the coal reservoir, and the CO2-specific surface area and CO2-total pore volume relationships show a positive linear correlation. The metamorphic degree has a much greater control on the pores (pore diameter less than 2 nm) structural parameters than those of the pore diameter ranges from 2 to 100 nm. Dv1 and Dv2 can characterize the structure of 2–100 nm adsorption pores, and Dv1 (volume heterogeneity) has a positive correlation with the pore structural parameters such as N2-specific surface area and N2-total pore volume. This parameter can be used to characterize volume heterogeneity of 2–10 nm pores. Dv2 (surface heterogeneity) showed type A > type B > type C and was mainly affected by the metamorphism degree. Ds2 can be used to characterize the pore surface heterogeneity of micropores in the range of 0.62–1.50 nm. This parameter has a good correlation with the pore parameters (CO2-total pore volume, CO2-specific surface area, and average pore size) and is expressed as type C < type B < type A. In conclusion, the heterogeneity of the micropores is less than that of the meso- and macropores (2–100 nm). Dv1, Dv2, and Ds2 can be used as effective parameters to characterize the pore structure of adsorption pores. This result can provide a theoretical basis for studying the pore structure compatibility of coal reservoirs in the region.

AbstractOBJECTIVESSegmentectomy has become an increasingly popular surgical procedure for small-sized lung lesions. Left upper trisegmentectomy (LUTS) is one of the most common segmentectomies performed because of its relative ease and simplicity; however, limited information is currently available on the specific postoperative complications associated with this procedure.METHODSAmong 2060 surgically resected cases in our institute between 2009 and 2016, 129 (6.2%) underwent LUTS. Postoperative chest X-rays and/or thoracic computed tomography (CT) scans were retrospectively assessed for all cases to assess postsurgical residual lung complications following LUTS. We categorized cases into 4 groups: type A (atelectasis of the lingular segment), type B (lung torsion of the lingular segment), type C (necrosis of the ‘isolated segment’) and type D (haematoma along stapling lines).RESULTSPostsurgical lung complications following LUTS were observed in 17 (13.1%) patients (type A: n = 7, type B: n = 1, type C: n = 4 and type D: n = 5). Three patients (2.3%) required surgical intervention because of type B (n = 1) and type C (n = 2), namely, decreased permeability and remaining ground glass opacities in the residual lung, showing an exacerbated systemic inflammatory response. In contrast, type A and D cases were successfully observed by chest CT without any surgical intervention, and patients recovered within a few months of surgery.CONCLUSIONSWe identified several postoperative residual lung complications following LUTS. Lung torsion or necrosis of the residual segment may require intensive care, including reoperation. Potentially serious complications always need to be ruled out after LUTS when radiological consolidation is detected postoperatively.

Low Permeability Reservoirs

Taking the example of the fourth member of the Lower Cretaceous Quantou formation reservoirs in fault block Sheng554 of Sanzhao sag, this article discusses the methodology of flow units in extra-low permeability reservoirs. The research on flow units in such reservoirs can be divided into two ranks, one is to determine the distribution of seepage barriers and inner connected sands， the other is to analyze the differentia of fluid flow in the inner connected sands so as to subdivide the flow units. The result shows that the pelitic barriers are rather developed in fault block Sheng554. Through the analysis of differentia of fluid flow, according to the value of flow zone index (FZI), the inner connected sands can be classified into three types of flow units, among which type A with FZI value greater than 1.0 has better permeable property and higher intensity of water injection, and the ability of permeability and water injection of type B with FZI value between 0.5 and 1.0 takes the second place, and type C is the worst flow unit with the worst permeable property and intensity of water injection with FZI value less than 0.5. Among the three types of flow units, type A poorly develops, while type B and type C develops well. The research on flow units can provide reliable geologic bases for forecasting the distribution of remaining oil in extra-low permeability reservoirs and for developing remaining oil in the study area.

Objectives: The aims of this study were to introduce a new classification of cochleovestibular malformation (CVM) and to investigate how well this classification can predict speech perception ability after cochlear implantation in children with CVM. Methods: Fifty-nine children with CVM who had used a cochlear implant for more than 3 years were included. CVM was classified into 4 subtypes based on the morphology of the cochlea and the modiolus on temporal bone computed tomography (TBCT): normal cochlea and normal modiolus (type A, n = 16), malformed cochlea and partial modiolus (type B, n = 31), malformed cochlea and no modiolus (type C, n = 6), and no cochlea and no modiolus (type D, n = 6). Speech perception test scores were compared between the subtypes of CVM using analysis of covariance with post hoc Bonferroni test. Univariate and multivariate regression analyses were used to identify the significant predictors of the speech perception test scores. Results: The speech perception test scores after implantation were significantly better in children with CVM type A or type B than in children with CVM type C or type D. The test scores did not differ significantly between the implanted children with CVM type A or type B and those without CVM. In univariate regression analysis, the type of CVM was a significant predictor of the speech perception test scores in implanted children with CVM. Multivariate regression analysis revealed that the age at cochlear implantation, cochlear nerve size and preimplantation speech perception test scores were significant predictors of the postimplantation speech perception test scores. The chance of cochlear nerve deficiency increased progressively from CVM type A to type D. Conclusion: The new classification of CVM based on the morphology of the cochlea and the modiolus is simple and easy to use, and correlated well with postimplantation speech perception ability and cochlear nerve status. This simple classification of CVM using TBCT with cochlear nerve assessment by magnetic resonance imaging is helpful in the preoperative evaluation of children with CVM.
