Monochorionic triamniotic triplet pregnancy with a co-triplet fetus discordant for congenital cystic adenomatoid malformation of the lung

BACKGROUND: Spontaneous monochorionic triamniotic pregnancy is rare and is at increased risk for pregnancy complications. The presence of an anomalous fetus further complicates the management. CASE PRESENTATION: We present a case of monochorionic triamniotic triplet pregnancy diagnosed at 15 weeks of gestation with one fetus having developed a multicystic lung lesion, suggestive of congenital cystic adenomatoid malformation (CCAM). At 24 weeks, the largest cyst measured 10 mm in diameter. We managed the pregnancy conservatively and delivered three live male fetuses with birth weights 1560 g, 1580 g and 1590 g at 35 weeks of gestation. Two newborns were admitted to the neonatal intensive care unit with respiratory distress, the third one died due to sepsis 7 days postpartum. One of the newborns was discharged healthy at 24 days postpartum. The newborn with CCAM developed a pneumothorax on the right side, recovered after treatment, and was discharged after one month. Computerized tomography (CT) of the infant at 3 months demonstrated two cystic lesions in the middle lobe of the right lung measuring 25 mm and 15 mm. A repeat CT of the infant at 6 months showed a 30 mm solitary cystic mass. CONCLUSION: Monochorionic triamniotic triplet pregnancy with a co-triplet fetus discordant for CCAM, present rarely and can be managed conservatively. These findings may help in decision making and counselling of parents

An improved method of photometric stereo using local shape from shading

This paper presents an improved photometric stereo (PS) method by integrating it with a local shape from shading (SFS) algorithm. PS produces the initial estimate of image for the global accuracy and also provides the recovery of albedo, SFS supplies the more detailed information within each homogeneous area. The quality of depth obtained by integrating PS and SFS is compared with the real depth using absolute dept error function, and the improvement ranging from 2.3 to 14% over PS is obtained

Performance results of the improved method of photometric stereo using local shape from shading on variable albedo samples

This paper presents the performance results of the improved photometric stereo (PS) method [1], which integrates PS and local shape from shading (SFS) algorithms, on the variable albedo samples. PS problem can be solved with the linear equation system by using at least three input images illuminated on different directions. SFS recovers the shape of object from a single image and it does not work on the variable albedo samples. The main idea of the integration of PS and SFS can be explained briefly as follows: PS produces the initial estimated depth for overcoming the global accuracy and recovering the albedo map; SFS supplies the more detailed information within each homegeneous area

Ottoman archives explorer: A retrieval system for digital Ottoman archives

This article presents Ottoman Archives Explorer, a Content-Based Retrieval (CBR) system based on character recognition for printed and handwritten historical documents. Several methods for character segmentation and recognition stages are investigated. In particular, sliding-window and histogram segmentation methods are coupled with recognition approaches using spatial features, neural networks, and a graph-based model. The prototype system provides CBR of document images using both example-based queries and a virtual keyboard to construct query words

Biomechanical effects of menopause in ovariectomized rats’ femurs

Objective: To demonstrate the biomechanical changes in rat bones occurred by surgical menopause and to search for correlation between biomechanical test results and bone mineral density (BMD) measurements

The Urgency of Disability Accessibility in Gorontalo District Government Agencies

Accessibility is the facilities provided for persons with disabilities to realize equality and opportunity and all aspects of life and livelihood as ease of moving through and using buildings and the environment with due regard to fluency and feasibility. The purpose of this study was to determine the Gorontalo District regional government policy in implementing the Act relating to the accessibility of the needs of persons with disabilities. Particularly on the accessibility of persons with disabilities to government agencies in Gorontalo District based on Law No. 8 of 2016 concerning Persons with Disabilities and universal design principles implemented in Ministerial Regulation No. 14 of 2017 concerning Building Easiness Requirements. This research uses a normative a juridical type of research with a juridical empirical approach. The results showed that (1). Implementation of Law No. 8 of 2016 concerning Persons with Disabilities in Gorontalo Regency has not been implemented optimally (2). Obstacles found in government agencies in the Gorontalo District environment include government buildings not yet accessible for persons with disabilities. This means that the facilities provided do not meet the universal design principles of ease, usefulness, safety, and independence. The absence of regulations in the form of Regional Regulations and Regents as a legal umbrella related to the standard facilities and services that must be provided for persons with disabilities, and the lack of local budgets for the development and construction of facilities related to the accessibility of persons with disabilities

Methylenetetrahydrofolate reductase C677T gene polymorphism in osteosarcoma and chondrosarcoma patients.

This study was designed to investigate the association of MTHFR C677T polymorphism and the risk of two common musculoskeletal sarcomas, osteosarcoma and chondrosarcoma. MTHFR genotypes were determined in 56 patients (44 osteosarcoma, 12 chondrosarcoma) and 44 controls using the PCR-RFLP technique. In the gender subgroup analysis, wild-type A allele frequency was higher in male osteosarcoma patients than in male control subjects (P = 0.064). Mutant V allele and mutant VV genotype were similar in the control group compared to the sarcoma groups (P > 0.05). No correlation could be proved between patient tumour site, presence of metastasis, and local tumour relapse and MTHFR polymorphism. The MTHFR C677T polymorphism may not be important in an individual's susceptibility to osteosarcoma and chondrosarcoma in Turkey and may not be a useful marker for identifying patients at high risk of developing sarcomas
