Recently, the online services have used widely in different fields for providing and facilitating user needs. Most of these services give the flexibility and easy to access anytime and anywhere without need to waste the time. This study was initialed for the current issues in determining the bed availability in the Libyan public hospital Al-Jumhouriya in Benghazi for pregnant. Thus, this study successful designed and developed the system based on the System Research Process Methodology. The system was developed based on JSP and MySQL tools and tested on local server. The result of the evolution found that the proposed Bed Reservation System (BRS) was easy to use, useful and achieve the uses intention in using it

Reconstruction of Long Anterior Urethral Strictures by Dorsally Quilted Penile Skin Flap

Objective. To present the results of reconstruction of long (>5 cm), penile, bulbar, and bulbopenile urethral strictures by penile skin flap as dorsal onlay in one-stage procedure. Patients and Methods. Between January, 1998 and December, 2004, 18 patients (aged from 28-65 years) presented with long urethral strictures, 5.6–13.2 cm (penile in 6, bulbar in 2 and combined in 10 cases), those were repaired utilizing long penile skin flaps placed as dorsal onlay flap in one stage (Orandi flap 6 cm in 6 cases, circular flaps 7–10 cm in 8, and spiral flaps 10–15 cm in 4). Followup of all patients after reconstruction included urine flow rate at weekly intervals, RUG at 6–12 weeks, and urethrocystoscopy at 12 and 18 months. Results. The urethral patency was achieved in 77% of patients. The complications were fistula in one patient (5.5%), restricture occurred in 3 patients (16.6%) that required visual internal urethrotomy and two patients (11%) showed curvature on erection that dose not interfere with sexual intercourse. Diverticulum (penile urethra) was seen in one patient (5.5%) containing stones and was excised surgically. There was penile skin loss in 3 patients (16.6%). All patients completed at least one-year followup period. Conclusion. Free penile skin flaps offer good results (functional and cosmetic) in long penile and/or bulbar urethral strictures. Meticulously fashioned longitudinal, circular or spiral penile skin flaps could bridge urethral defects up to 15 cm long

Diagnosis of Viral Diseases in Sudan: Coronaviruses Unveil the Concealed Venues

Establishing the diagnosis of viral diseases often needs sophisticated settings, equipment, expertise, and strict laboratory methods.  In Sudan, as in most developing countries, viral diseases are mostly diagnosed by clinical presentation. As most viral infections are self-limiting and there is no specific treatment for most of them, laboratory diagnosis has not been a focus for improvement, particularly in public sector until the current pandemic of COVID-19. During this pandemic, the vital need for well-equipped clinical virology laboratories is urged. The aim of this work is to highlight the various diagnostic methods and to describe the current situation of clinical virology diagnostics in Sudan

Recent Advancements in Fractal Geometric-Based Nonlinear Time Series Solutions to the Micro-Quasistatic Thermoviscoelastic Creep for Rough Surfaces in Contact

To understand the tripological contact phenomena, both mathematical and experimental models are needed. In this work, fractal mathematical models are used to model the experimental results obtained from literature. Fractal geometry, using a deterministic Cantor structure, is used to model the surface topography, where recent advancements in thermoviscoelastic creep contact of rough surfaces are introduced. Various viscoelastic idealizations are used to model the surface materials, for example, Maxwell, Kelvin-Voigt, Standard Linear Solid and Jeffrey media. Such media are modelled as arrangements of elastic springs and viscous dashpots in parallel and/or in series. Asymptotic power laws, through hypergeometric series, were used to express the surface creep as a function of remote forces, body temperatures and time. The introduced models are valid only when the creep approach of the contact surfaces is in the order of the size of the surface roughness. The obtained results using such models, which admit closed-form solutions, are displayed graphically for selected values of the systems' parameters; the fractal surface roughness and various material properties. Results obtained showed good agreement with published experimental results, where the utilized methodology can be further extended to the utilization for the contact of surfaces within micro- and nano-electronic devices, circuits and systems

Layperson perception of reflux-related symptoms

OBJECTIVE: To assess for differences of intended meaning in the description of reflux-related symptoms among otolaryngology patients and clinicians. STUDY DESIGN: Cross-sectional survey-based study. SETTING: Five tertiary, academic otolaryngology practices. METHODS: Between June 2020 and July 2022, a questionnaire consisting of 20 common descriptors of reflux-related symptoms within four domains (throat-, chest-, stomach-, and sensory-related symptoms) was completed by patients. Attending otolaryngologists at five academic medical centers then completed the same survey. The primary outcome was to assess differences in patient and clinician perceptions of reflux-related symptoms. Differences based on geographic location was a secondary outcome. RESULTS: A total of 324 patients and 27 otolaryngologists participated. Patients selected a median of six terms compared with 10.5 for otolaryngologists ( CONCLUSION: There are differences between otolaryngologists and their patients in the interpretation of the symptoms of reflux. Patients tended to have a narrower interpretation of reflux with symptoms primarily limited to classic stomach-related symptoms, while clinicians tended to have a broader definition of reflux that included extra-esophageal manifestations of disease. This has important counseling implications for the clinician, as patients presenting with reflux symptoms may not comprehend the relationship of those symptoms to reflux disease

Effectiveness of ovarian suspension in preventing post-operative ovarian adhesions in women with pelvic endometriosis: A randomised controlled trial

<p>Abstract</p> <p>Background</p> <p>Endometriosis is a common benign condition, which is characterized by the growth of endometrial-like tissue in ectopic sites outside the uterus. Laparoscopic excision of the disease is frequently carried out for the treatment of severe endometriosis. Pelvic adhesions often develop following surgery and they can compromise the success of treatment. Ovarian suspension (elevating both ovaries to the anterior abdominal wall using a Prolene suture) is a simple procedure which has been used to facilitate ovarian retraction during surgery for severe pelvic endometriosis. The study aims to assess the effect of temporary ovarian suspension following laparoscopic surgery for severe pelvic endometriosis on the prevalence of post-operative ovarian adhesions.</p> <p>Methods</p> <p>A prospective double blind randomised controlled trial for patients with severe pelvic endometriosis requiring extensive laparoscopic dissection with preservation of the uterus and ovaries. Severity of the disease and eligibility for inclusion will be confirmed at surgery. Patients unable to provide written consent, inability to tolerate a transvaginal ultrasound scan, unsuccessful surgeries or suffer complications leading to oophorectomies, bowel injuries or open surgery will be excluded.</p> <p>Both ovaries are routinely suspended to the anterior abdominal wall during surgery. At the end of the operation, each participant will be randomised to having only one ovary suspended post-operatively. A new transabdominal suture will be reinserted to act as a placebo. Both sutures will be cut 36 to 48 hours after surgery before the woman is discharged home. Three months after surgery, all randomised patients will have a transvaginal ultrasound scan to assess for ovarian mobility. Both the patients and the person performing the scan will be blinded to the randomisation process.</p> <p>The primary outcome is the prevalence of ovarian adhesions on ultrasound examination. Secondary outcomes are the presence, intensity and site of post-operative pain.</p> <p>Discussion</p> <p>This controlled trial will provide evidence as to whether temporary ovarian suspension should be included into the routine surgical treatment of women with severe pelvic endometriosis.</p> <p>Trial registration</p> <p>ISRCTN: <a href="http://www.controlled-trials.com/ISRCTN24242218">ISRCTN24242218</a></p
