Occurrence of anembryonic pregnancy with use of levonorgestrel subdermal implant (JADELLE®): a case report

Progestin-only subdermal implants are one of the most effective contraceptive methods. Anembryonic pregnancy is not reported as a possible outcome in cases of contraceptive failure of these products. We presen...

Ear Prosthesis for Postburn Deformity

Prosthodontics is not just confined to replacement of missing teeth but beyond one's scope. The fabrication of any extraoral maxillofacial prosthesis presents the prosthodontist with several phenomenal challenges. Psychologically, these patients are severely affected either by congenital absence or loss of ear due to trauma or burns. Replacement or reconstruction can be done by surgical or prosthetic approach. However, not all situations are favourable to surgical reconstruction. This article emphasises on the steps in fabrication of ear prosthesis for burn deformity.

A comparison of morpho-syntactic abilities in deaf children with cochlear implant and 5-year-old normal-hearing children

Publication date: July 2018
Source:International Journal of Pediatric Otorhinolaryngology, Volume 110
Author(s): Samane Dehghani Golestani, Nahid Jalilevand, Mohammad Kamali
IntroductionChildren with cochlear implants (CIs) have problems in morpho-syntactic abilities more than other language skills. The current study was aimed to evaluate the language samples of children with CIs by using a numerical measurement tool, Persian developmental sentence scoring (PDSS).MethodIn this cross-sectional, descriptive, analytical study, 33 children (22 children with CIs and 11 with normal hearing) were recruited. Language samples of the children were recorded during the description of pictures. The PDSS was used as a reliable numerical measurement tool for analyzing the first 100 consecutive intelligible utterances.ResultsWe found a significant difference in the mean PDSS total scores (p = 0.0001) between the normal-hearing children and deaf children using CIs for 5 years. Similarly, the results revealed a significant difference in the mean PDSS total scores (p = 0.0001) between the normal-hearing children and 5-year-old deaf children with CIs. There was no significant difference in the mean PDSS total scores between the two groups of children with CIs.ConclusionChildren with CIs can form simple sentences but probably exhibit poor abilities for using complex sentences and essential morphology items.

Changes of biotoxicity in food waste fermentation wastewater treated by a membrane bioreactor system

Abstract

The biotoxicity of industrial effluents has attracted much concern in the wastewater treatment process. This research performed the biological treatment of the wastewater generated from food waste fermentation by anaerobic/anaerobic/anoxic/aerobic-membrane bioreactor (A³-MBR) system aiming at the meet of discharge standards and elimination of ecological risks to aquatic environment. The results showed that the A³-MBR could effectively remove pollutants such as COD, TN, ammonia, and TP in the wastewater. The study of biotoxicity revealed that the acute toxicity was mainly contained in the polar and mid-polar fractions of the wastewater, and the remained acute toxicity was less than 0.6 TU, much lower than the secondary effluent of domestic wastewater treatment plant. The genotoxicity was found abundantly in the polar fractions and less in mid-polar fractions, and a relatively low genotoxicity (0.086 μg 4-NQO/L) was obtained in the final effluent of the treatment system. The fulvic acid-like compounds and humic acid-like compounds were the main cause of the acute toxicity, while the aromatic proteins and soluble microbial by-products mainly resulted in the genotoxicity in the wastewater.

Impact of selected drugs and their binary mixtures on the germination of Sorghum bicolor (sorgo) seeds

Abstract

The aim of this study was to assess the toxicological potential of binary drug mixtures and individual drugs under different pH conditions with different inorganic ion additions on the germination of Sorghum bicolor (sorgo) seeds. To assess whether the given drug mixtures were more phytotoxic than the individual compounds, concentration addition (CA) and independent action (IA) approaches were applied to estimate the predicted phytotoxicity values, followed by calculations of the MDR (model deviation factor) to determine the deviation from the predicted values. Binary mixtures of chloramphenicol with ketoprofen, diclofenac sodium, and oxytetracycline hydrochloride proved to be synergistic. The pH changes had the largest impact on the phytotoxicity of the diclofenac sodium and ketoprofen solutions, elevating their toxicity toward S. bicolor, and the co-presence of inorganic ions was shown to have an impact on ketoprofen, chloramphenicol, and oxytetracycline hydrochloride. Most of the interactions between sorgo plants and pharmaceuticals with added ions were antagonistic in nature, particularly those calculated using the IA model, with a few cases (one case for ketoprofen and chloramphenicol, two cases for oxytetracycline hydrochloride, and four cases for diclofenac sodium) of overestimation.

Fat Embolism Syndrome: A Case Report and Review Literature

Fat embolism syndrome (FES) is a life-threatening complication in patients with orthopedic trauma, especially long bone fractures. The diagnosis of fat embolism is made by clinical features alone with no specific laboratory findings. FES has no specific treatment and requires supportive care, although it can be prevented by early fixation of bone fractures. Here, we report a case of FES in a patient with right femoral neck fracture, which was diagnosed initially by Gurd's criteria and subsequently confirmed by typical appearances on magnetic resonance imaging (MRI) of the brain. The patient received supportive management and a short course of intravenous methylprednisolone.

Facile synthesis of highly porous “carbon sponge” with adsorption and co-adsorption behavior of lead ions and atrazine

Abstract

The rapid industrialization and modern agriculture, increasing emission of heavy metals, and abusing application of pesticide have changed biochemical features of the soil system and water system. Additionally, heavy metals and pesticide compounds may occur together in environments, giving rise to more serious damage to the environment because of their combined toxicity and carcinogenic properties. Therefore, there is a growing need for the development of low-cost adsorbents for their removal. Porous carbon materials have been considered as highly effective materials for pollutant ion control. In this thesis, a novel porous "carbon sponge" is produced using sucrose (S-PCS) with gas-producing molten salt KHCO₃ as the activator at different pyrolysis temperatures under a limited-oxygen condition. Results from these characterizations have indicated that the as-prepared carbon sponges share high surface area (up to 457.6434 m² g⁻¹) and abundant oxygen-containing functional groups existed on the surface. The essential factors of contact time, initial concentrations, and cyclic availability on adsorption of lead ions and atrazine onto the as-prepared porous samples are also discussed. The typical kinetic and thermodynamic models are carried out to interpret the adsorption behaviors of lead ions and atrazine. The interactive effects and mechanism of lead ions and atrazine adsorption onto S-PCS samples are examined by simultaneous adsorption and preloading adsorption procedures. Combined with the economic and environmental merits of the raw materials, the porous carbon sponges of sucrose by KHCO₃ activated are promising materials for potential practical applications.
