Successful intralesional bleomycin injections for the management of a huge life-threatening cervical lymphangioma in a 3-day-old neonate

Intralesional bleomycin injections (IBI) for the management of a huge life-threatening cervical cystic hygroma is superior to surgery. Surgery has a high rate of morbidity and even mortality. Recurrence and injury to major vessels, nerves, and lymphatics may be unavoidable. The authors report on a 3-day-old male infant who was diagnosed antenatally as a case of a huge cervical cystic hygroma. Postnatally, the patient required mechanical ventilation. The patient was treated successfully with IBI without complications. To our knowledge, this is the youngest case presenting acutely to be treated successfully with IBI without complications.Keywords: bleomycin, neonatal cystic hygroma, respiratory distres

Influence of temperature, salinity and Mg:Ca ratio on microbially-mediated formation of Mg-rich carbonates by Virgibacillus strains isolated from a sabkha environment.

Studies have demonstrated that microbes facilitate the incorporation of Mg into carbonate minerals, leading to the formation of potential dolomite precursors. Most microbes that are capable of mediating Mg-rich carbonates have been isolated from evaporitic environments in which temperature and salinity are higher than those of average marine environments. However, how such physicochemical factors affect and concur with microbial activity influencing mineral precipitation remains poorly constrained. Here, we report the results of laboratory precipitation experiments using two mineral-forming Virgibacillus strains and one non-mineral-forming strain of Bacillus licheniformis, all isolated from the Dohat Faishakh sabkha in Qatar. They were grown under different combinations of temperature (20°, 30°, 40 °C), salinity (3.5, 7.5, 10 NaCl %w/v), and Mg:Ca ratios (1:1, 6:1 and 12:1). Our results show that the incorporation of Mg into the carbonate minerals is significantly affected by all of the three tested factors. With a Mg:Ca ratio of 1, no Mg-rich carbonates formed during the experiments. With a Mg:Ca ratios of 6 and 12, multivariate analysis indicates that temperature has the highest impact followed by salinity and Mg:Ca ratio. The outcome of this study suggests that warm and saline environments are particularly favourable for microbially mediated formation of Mg-rich carbonates and provides new insight for interpreting ancient dolomite formations

Effect of Pregnancy on Haematological and Biochemical Profiles in the Mountain Gazelles (Gazella gazelle)

Abstract: The propose of this study was to investigate the effect of pregnancy on hematological and biochemical parameters. This parameters were measured in 20 blood samples collected from 10 pregnant and 10 non-pregnant captive mountain gazelles (Gazella gazella) in Saudi Arabia. The effects of pregnancy on the intracellular concentrations of sodium (Na + ), Potassium (K + ), Blood Urea Nitrogen (BUN), Alanine amino Transferase (ALT), Aspartate amino Transferase (AST), Total protein, albumin, Alkaline Phosphatase (AP), Creatinine, Cholesterol and Triglyceride were analyzed. The levels of Sodium ions, GGT, ALT, AST, cholesterol and triglycerides were significantly (p<0.01) increased in pregnant group compared to non-pregnant group. These result due to the physiological and metabolism changes during pregnancy. So this study suggested to supply pregnant Gazelles with proteins during pregnancy

Linking depositional environments and diagenetic processes to porosity evolution and destruction in the Arab Formation reservoirs, Offshore oilfields of Qatar

Introduction: The Jurassic Arab Formation is the main oil reservoir in Qatar. The Formation consists of a succession of limestone, dolomite, and anhydrite. Materials and Methods: A multi-proxy approach has been used to study the Formation. This approach is based on core analysis, thin sections, and log data in selected wells in Qatar. Results: The reservoir has been divided into a set of distinctive petrophysical units. The Arab Formation consists of cyclic sediments of oolitic grainstone/packstone, foraminifera-bearing packstone-wackestone, lagoonal mudstone and dolomite, alternating with anhydrite. The sediments underwent a series of diagenetic processes such as leaching, micritization, cementation, dolomitization and fracturing. The impact of these diagenetic processes on the different depositional fabrics created a complex porosity system. So, in some cases there are preserved depositional porosity such as the intergranular porosity in the oolitic grainstone, but in other cases, diagenetic cementation blocked the same pores and eventually destroyed them. In other cases, diagenesis improved the texture of non-porous depositional texture such as mudstone through incipient dolomitization creating inter-crystalline porosity. Dissolution created vugs and void secondary porosity in otherwise non-porous foraminiferal wackestone and packstone. Therefore, creating a matrix of depositional fabrics versus diagenetic processes enabled the identification of different situation in which porosity where either created or destroyed. Future Directions:By correlating the collected petrographic data with logs, it will become possible to identify certain "facio-diagenetic" signatures on logs which will be very useful in both exploration and production. Studying the micro and nano-porosity will provide a better understanding of the evolution and destruction of its porosity system

Remote sensing of inland Sabkha and a study of the salinity and temporal stability for sustainable development: A case study from the West coast of Qatar

The inland sabkha of the Arabian Gulf is important to study for the occurrence of minerals, rocks, soil salinity, and stability of the sabkha due to the high demand for infrastructure and agriculture development region. This study describes the spectral absorptions of evaporite minerals, discriminates rocks, maps salt crusts, gypsiferous soil flats, and soil salinity, and studies the temporal stability of an inland sabkha of the Dukhan area, west coast of the State of Qatar. This was performed using satellite data of the Hyperion of EO1, ASTER of Terra, and multispectral instrument (MSI) of Sentinel-2. The occurrence of minerals in the area is detected using Hyperion data by the linear spectral unmixing (LSU) method and studied for their spatial distribution. The different geological formations of the sabkha were discriminated by using the VNIR (visible and near-infrared) and SWIR (shortwave infrared) spectral bands from ASTER by principal component analysis (PCA). The image developed by using the principal components (R:PC2, G:PC3, B:PC5) showed the formations in different tones. Salinity of the area was mapped using monthly data of MSI from 2018 to 2020 by normalized difference salinity index (NDSI) (band11-band12)/(band11 + band12). The results of the index displayed the distribution of salinity in the area. Besides, moisture of the area was studied by using the normalized difference moisture index (NDMI) (b8-b11)/(b8 + b11) and described the temporal stability of the sabkha. All the results of image analyses were validated through field and laboratory studies. The study of laboratory spectra of evaporite minerals namely gypsum, anhydrite, and halite present in the salt crusts and gypsiferous soil flats showed their unique spectral absorptions in between 1.4–1.5 μm and 1.9–2.0 μm whereas, the calcite and dolomite minerals of the carbonate formations exhibited deep absorptions near 2.345 and 2.495 μm respectively.This study was supported by the Qatar National Research Fund under the National Priorities Research Program (grant no NPRP10-0214-170462)

Negative Pressure Wound Therapy (NPWT) in Breast Surgery

Background: The use of Negative Pressure Wound Dressing has been found to promote the wound healing process, therefore, reducing the risk of surgical site complications. The use of this technique amongst breast cancer patients, who have often encountered a distressing journey, may prove beneficial in making the post-operative process less eventful. Many of these patients have a limited time window to start adjuvant treatment. The use of a negative pressure device is recommended in both prophylactic and therapeutic scenarios. NPWT may also be used in patients who have undergone cosmetic breast surgery. We have evaluated the use of NPWT in breast surgery with an updated and systematic review of the available literature. Methods: The authors systematically searched the PubMed, Science Direct, and Wiley Online databases using the phrases “Negative Pressure Wound Therapy in Breast surgery” and “Vacuum-Assisted Closure in Breast Wound” and all publications, including relevant data were considered eligible for inclusion in the review. Results: We have found reports of 7 studies, 3 retrospective, 2 prospective, one randomized trial, and one case series. The complication rate in the NPWT group versus conventional dressing group has been reported in 5 papers. A statistically significant effect in favor of NPWT was documented in three trials. Conclusion: The current evidence supports the notion that NPWT systems are beneficial in enhancing the healing of complicated breast wounds. However, larger studies exploring the effectiveness of this technique would be of interest to breast surgeons

Mapping of aeolian deposits of an industrial site in the arid region using the TIR bands of ASTER and study of physicochemical characters and stabilization of sand erosion

This study describes the spectral emissive character of silicate and carbonate minerals of aeolian deposits and maps the deposits and sand encroachments that occurred in and around the site 5/6 of Qatar Fertilizer Company (QAFCO), Qatar using thermal infrared (TIR) bands of ASTER. The results of studies show that the quartz and unaltered silicates have spectral features between 8.12 and 9.27 µm, and the calcite and dolomite have emissivity minima near 11.4 and 11.2 µm, respectively. The mapping of deposits, dunes, and carbonate formations using the bands, and quartz index (QI), and carbonate index (CI) displayed their occurrence, distribution, and direction of sand movement from NW to SE. The sand encroachment was mapped using high spatial resolution satellite data of WorldView-2. The study of physicochemical characteristics of field samples showed the occurrence of sand grains up to 99.81% and the XRD and geochemical analyses represented the presence of quartz, calcite, dolomite, albite, and halite minerals in the deposits. In addition, the bacterial strains isolated from the samples indicated high urease activity leading to precipitation of carbonate minerals via microbially induced calcite precipitation (MICP) processes, and demonstrated high potential for utilization for sand stabilization of the QAFCO site

Sentinel-2 image transformation methods for mapping oil spill – A case study with Wakashio oil spill in the Indian Ocean, off Mauritius

Although several indices have been constructed and available at the Index database (IDB) for Sentinel-2 satellite to map and study several earth resources, no indices have been developed to map oil spill. We constructed band ratios (5 + 6)/7, (3 + 4)/2, (11+12)/8 and 3/2, (3 + 4)/2, (6 + 7)/5 using the high-resolution MSI (multi-spectral instrument) visible-near infrared-shortwave infrared spectral bands of Sentinel-2 by summing-up the bands representing the shoulders of absorption features as numerator and the band located nearest to the absorption feature as denominator to discriminate oil spill, and demonstrate the potential of this method to map the Wakashio oil spill which occurred in the Indian Ocean, off Mauritius. The resulted images discriminated the oil spill well. We also decorrelated the spectral bands 4, 3 and 2 by studying the spectral band absorptions and discriminated the spill as very thick, thick and thin. The results of decorrelation stretch method exhibited the distribution of types of oil spill in a different tone, distinctly. Both the image transformation methods (band ratios and decorrelation stretch methods) showed their capability to map oil spills, and these methods are recommended to use for similar spectral bands of other sensors to map oil spills. • This study demonstrated the application of band ratios and decorrelation stretch methods to map oil spill. • The methods discriminated the oil spill off Mauritius, and showed spill thicknesses from the Sentinel-2 data. • The new methods are recommended to use for the spectral bands of other sensors to map oil spill.This work was supported by the Qatar University’s International Research Collaboration Co-Funds project (IRCC-2019-002).
