COVID-19 Outbreak: Routes of Transmission, Precautions, and Economic Impact on Dentistry-A Review Article
Get PDFIn late 2019, a novel coronavirus appeared in Wuhan, Hubei province, China, and then rapidly spread around the world. The virus produces severe and even fatal pneumonia; the most common clinical symptoms among infected persons include fever, shortness of breath, cough, fatigue, and abnormal chest CT. Though the virus first traveled from animal to human, it can now spread from human to human through direct transmission such as coughing, sneezing, and inhalation of droplets; and through contact with mucus membranes of oral, nasal, and eye. COVID-19 also can be transmitted through saliva and the fecal–oral route. The risk of cross-infection between patients and dental practitioners is high due to the nature of dental work, so this outbreak has made a powerful impact, both medically and economically, on the dentistry sector. Dental practitioners should have comprehensive knowledge of the virus and its route of transmission, and they should take proper precautions during dental treatments to protect themselves and their patients. This article provides a review of COVID-19, its transmission routes, necessary precautions during dental setting, and the virus’s impact on the economy of the dental industry

Optimization of Tilt Angle of a PV System to Get Maximum Generated Power: a Case Study
Get PDFThe amount of solar irradiance falls onto photovoltaic (PV) panels depends highly on the tilt angle between the panels and the horizontal plane. Therefore, this angle must be chosen carefully so that the panels can absorb the largest possible amount of the solar beam. It is more convenient for the panels to be installed with the fixed tilt angle once a month or year as the cost and complexity of the solar tracking systems are high. This research determines monthly and yearly optimum tilt angles for 50 KWp solar system in Duhok city, Duhok Polytechnic University campus (Latitude/Longitude: 36.862, 42.980). Moreover, this work examines the performance of the system with different PV technologies which are Crystalline Silicon, Cadmium Telluride (CdTe), and Copper Indium Selenide (CIS) to determine which one is more convenient for Duhok weather. This work uses the PVGIS simulation tool, and the result shows that the 32.7 degree is the optimum tilt angle for fixed annually adjustment for the mentioned city. While the monthly optimum tilt angles were different for each month (the lowest tilt angle was 1.5? observed in June and the highest tilt angle was 63.9? recorded in December). Regarding PV technologies, the CdTe types generated more annual PV energy than other mentioned types, followed by CIS which produced more output PV energy than Crystalline Silicon
Comparative Study of Diode Laser Versus Intense Pulsed Light (IPL) for the management of Hirsutism in Sulaimani Government
Get PDFHirsutism defined as excessive hairiness, hirsutism can negatively affect individuals, particularly females. Hirsutism has been attributed to the presence of high levels of androgen. There are different procedures to treat hirsutism; however, diode laser and intense pulsed light (IPL) are the most common methods. The present study was carried out in order to compare diode laser and IPL procedures regarding their effectiveness in decreasing hirsutism, patient satisfaction, and pain level. The present cross-sectional prospective study was carried out on 66 patients with hirsutism who regularly visited a dermatology clinic in Sulaimani, Kurdistan Region-Iraq over a period of 8 months from February to October 2020. They were assigned into a diode laser group (n=35) and an IPL group (n=31). Each patient had 8 laser sessions, once every month. Required data were collected through photos taken in every session. The collected data were analyzed through Statistical Package for the Social Sciences (version 22.0). The patients’ mean age was 33.12 years. Over 53% and 35% of them had a family history of first- and second- degree hirsutisms, respectively. Both procedures led to good and very good primary outcomes in 43.9% and 36.4% of the patients, respectively. Patient satisfaction was high in 42.4% of them. Our research has showed that IPL has fewer side effects (p-value<0.001), better primary outcome (p-value<0.001), and better patient’s mood (p-value<0.002). The two procedures led to similar level of patient satisfaction, and they were not significantly different in this regard (p-value=0.3). In terms of hair types, the two procedures were significantly different (p-value<0.001), such that IPL was better for thin hair, while diode laser for thick hair. Both diode laser and IPL procedures were found to be efficient in terms of primary outcome, patient satisfaction, and patient’s mood. However, diode laser is proper for dark-skinned patients with thick hair and IPL for thin hair. Diode laser was found to be better choice for our patients because most clients in the region are dark-skinned with thick hair

Get PDFTo compare the effects of using motorized diamond burr polisher in pterygium excision versus manual polishing of the corneoscleral bed in reducing the recurrent rate. A prospective, comparative and interventional study of 90 consecutive patients with different grads of primary pterygium, who underwent pterygium excision at Shahid Aso teaching eye hospital in Sulaimani city, between August 2018 till September 2019, which was performed by single surgeon. In group A (45) eyes polishing of the corneoscleral bed done using motorized diamond polishing burr, and in group B (45) eyes using manual crescent blade for polishing. Recurrent rate was evaluated after about (8±2) months postoperatively. Ethical consideration of the risks and the benefits of the procedure was observed for each individual patient. A 90 patients with the mean age of group A (48.84±12.7) years and group B (49.67±12.3) years, complained of different grads of primary pterygium, group A had 31(68.9%) male and 14(31.1%) female, while group B had 22(48.9%) male and 23(51.1%) female. Each individual factors like age, gender, visual acuity, BCVA pre and postoperatively, IOP measurement, dryness of the eye and risk factors like smoking and UV exposure affecting the recurrence were assessed. In both groups the main indication for surgery was sign of irritation. The mean surgical time was calculated and the difference between two groups were significant. After follow-up of average six months the outcomes and recurrent rate were checked, recurrent rate was in group A 1(2.2%) while in group B was 6(13.3%) patients. it significantly decreased. Corneal scar happens in only 1(2.2%) case of group A while in 11(24.4%) cases in group B, Corneal scar was statistically significant. In both groups the change of BCVA was significant but the visual change was more significant in group A in compare to group B. Motorized diamond burr is a safe instrument for polishing the cornea during pterygium excision, it is easy to handle, low price, need lesser operative time, its effect on recurrence postoperatively is significant and beside it leaves lesser corneal scar and early visual recovery postoperatively.  
Exploration of Cosmetic Factors Contributing to Rhinoplasty among Both Genders in Iraqi Kurdistan
Get PDFThe most outstanding feature of face is the nose which is in furthering than any other feature to facial characteristics. Furthermore, the appealing aspects of the nose is an essential olfactory organ. Over and beyond the aesthetic and functional aspects the client's reaction to his/her own nose as well as the reaction of the people around to it impacts to the psychic characteristics. A non-probability purposive sample of this cross - sectional descriptive study was consisted of 100 young male and female in Kurdish ethnicity, their ages ranged between 21-25 years. The main objective of the study is conducted to assess the cosmetic factors, contribute to Rhinoplasty among both genders at Raparin District. The data collecting period were during the (December 15th, 2019 to January 5th, 2020). A self-administration questionnaire was used for data collection and it was designed according guidelines, literatures, and articles concerning Rhinoplasty; which consisted of 26 variables. Data were analyzed using SPSS Version 23. The study results revealed that most of participants (67%) were female when only (17%) of them were married, however, more than half (67%) were students. Whenever, they about (56%) were barely sufficient in their monthly income. Moreover, about (61%) of participants interested to surgically alter the appearance of their nose, closely two-third (74%) of participants wanted to surgically change the function of their nose. Therefore, almost (87%) of participant relatives have been operated with Rhinoplasty. Also, the study demonstrated there is a statistically significant relationship between cosmetic factors contributing to Rhinoplasty with age (p=0.035) and occupation (p=0.037). When, there were strongly statistically significant association between cosmetic un-functional factors contributing to Rhinoplasty with level of education (p=0.003). The study recommended to plastic surgeons evaluate patients carefully before Rhinoplasty surgery to get rid of unnecessary surgeries because there are lots of complications related to Rhinoplasty and the psychological needs of the patients who undergo Rhinoplasty should be considered
Molecular Characterization of Methicillin Resistant and Extended Spectrum ?-Lactamase Staphylococcus aureus Isolated from Burn Patients
Get PDFAntibiotic resistance has become a major world health challenge and has limited the ability of physician's treatment. Staphylococcus aureus the most notorious pathogens causes morbidity and mortality especially in burn patients. However, Staphylococcus aureus rapidly acquired resistance to multiple antibiotics. Vancomycin, a glycopeptide antibiotic remains a drug of choice for treatment of severe Methicillin Resistance S. aureus infections. This study aimed to detect the emergence of beta-lactam and glycopeptide resistance genes. 50 clinical specimens of S. aureus collected from burn patients in burn and plastic surgery units in Sulaimani-Iraq city. All specimens were confirmed to be positive for S. aureus. All the isolates were assessed for their susceptibility to different antibiotics depending on NCCL standards, followed by Extended Spectrum Beta Lactamase detection by double disk diffusion synergy test. The production of ?- lactamases was evaluated in the isolated strains by several routine methods and polymerase chain reaction. Among the isolates 94% were Methicillin resistance and 34.28% were Extended Spectrum Beta Lactamase producer. PCR based molecular technique was done for the bla genes related to ?- lactamase enzymes by the specific primers, as well as genes which related to reduced sensitivity to Vancomycin were detected. The results indicated that all isolated showed the PBP1, PBP2, PBP3, PBP4, trfA and trfB, graSR, vraS except the vraR gene and the prolonged therapy of Methicillin resistance infection with teicoplanin have been associated with progress of resistance and the rise of tecoplanin resistance may be a prologue to evolving Vancomycin resistance. In conclusion, beta-lactam over taking can rise Vancomycin- Intermediate S. aureus strains leading to appearance of Vancomycin resistance although the treatment of Vancomycin resistant infections is challenging

The mean IgG (6.3±5.1) of patients with ectopic pregnancy was found to be significantly higher than mean IgG (2.8±1.1) for normal pregnant patients (P-value 0.01) and IgM mean (4.5±2.4) of patients with ectopic pregnancy was significantly higher than mean IgM (1.6±1.2) for normal pregnant patients with P-value 0.01. In conclusion, infection of Chlamydia Trachomatis has a significant relationship with the development of ectopic pregnancy therefor screening and treatment of Chlamydia infection may reduce ectopic pregnancy rate with low cos
Study of Uplink Interference in UMTS Network: ASIACELL Company, Iraq
Get PDFUniversal Mobile Telecommunications System (UMTS), is the third generation (3G) of mobile communication which is based on the wideband code division multiple access (W-CDMA) radio access to provide bandwidth and spectral efficiency. Interference in 3G system is significantly lower compared to the preceded generations. However, it does not mean 3G is free from the issues associated with interferences, such as low signal quality and call drop. The interference level in UMTS can be measured by using the well-known parameter Received Total Wideband Power (RTWP). This parameter is affected by many factors such as number of the users connected to the system, combining second generation (2G) and 3G frequencies within the same geographical area, geographical causes (difference of Altitude), and hardware impairment. In this paper we intensively study how these factors affect the uplink interference level (i.e. RTWP value) in 3G system used by a particular telecommunications company, Asiacell company, Iraq. The obtained data shows that call drop is the most serious issue raised due to high value of RTWP in 3G system. We demonstrate that system enhancement, in terms of lower RTWP level, are obtained by adding second carrier to the sites, separating 2G band from 3G band using special filter, and optimizing the hardware components.
