Removal of Neutral Red from Aqueous solutions usingSr2CaBO5.5 (B= Nb+5& Ta+5)

Two samples of the defectdouble perovskites with general formula Sr2CaNbO5.5 and Sr2CaTaO5.5 were synthesized and their cap abilities in the removal of neutral red dye investigated. Both samples have faced cubic perovskite-type structure in space group Fm3m. The replacement of Nb5+ by Ta5+ has influenced both crystal size and density of the two oxides but showed no impact on the removal capacities. The crystallite size of Sr2CaNbO5.5 and Sr2CaTaO5.5 was determined to be 93.56 and 43.69 nm respectively. The maximum removal capacities of Neutral red are found to be 190.5 mg/g using both the two oxides. This result is consistent with the cell volumes which displayed similar values. The removal of Neutral Red has a negative relationship with temperature but steadily increases as pH increased.

RETRACTED: Non-Surgical Removal of Basal Cell Carcinoma by Apis Mellifera L Venom

This article has been retracted on March 01, 2021. VIEW THE RETRACTION NOTICE (https://openaccesspub.org/jsce/article/2243) Background Apis Mellifera L venom (Honeybees) is potent and safe anticancer drug. The present case is Basal Cell Carcinoma (SBCC), recurrent and invasde the skin of head (upper right, in front of the right ear). The patient was 65 years old in time of first intervention and the origin of BCC was primarily seen as abnormal growths and changes in birth mole on right side of head. Materials & Methods Preparation Bee Venom solution: Bee venom powder (crude) of dose 1gm was dissolved in 1000 ml of sterile distilled water then filtered by 0.22 micron syring filter. That final concentration of the stock bee venom become 1 ug /ml (i.e. 1ul=1 ug), and kept at -20◦C. (1mg (dried BV) + 1ml (water) = Final concentration (1ug/1 ul)). Before this novel intervention, allergy test performed by subcutaneous injection of small dose of bee venom (0.1 ml) and wait for at least one hour. The patient was not hypersensitive to honeybees’ venom. First stage of treatment: 1- Syringe of 1ml volume was used for direct local injection of cancer area by 0.3 ml from prepared Honeybees venom (0.1 % conc.). 2- At the same time, subcutaneous injection of 0.5 ml of bee venom solution infiltrated around the affected ear. 3- Topical application of the bee venom ointment 2% (bee venom in Vaseline) inside affected ear to protect the ear drum. This process repeated daily with cleaning of the ear every time by suitable safe and sterile saline solutions. 2nd stage: daily S/C injection in axillary area upper lymph nodes of 0.3 ml / bee venom ‘total doses 0.6 ml BV’ (left & right). 3rd stage: bee venom dissolved in sterile Clove oil was applied on inner ear above the drum. 4th stage: Management of healing process was enhanced by ascorbic acid solution as topical application on dead cancer cells and to help in removal of exudates and debris. Results The complete removal of malignant growths in affected ear achieved after 1 month from first bee venom injections. However; the cancerous areas under the second surgical intervention were treated during the next month. Conclusions Apis Mellifera L venom as anticancer drug is totally different from using direct stings as a method of Apitherapy, that because collection of bee venom lead to evaporating of most allergic substance that present in bees stings, also it can be used per os in people who exhibit different degrees of allergy against the drug safely.

Removal of Methyl Violet from Aqueous Solutions Using the A Site Doped Perovskite +-Oxides BaxSr3-xNbO5.5 (x=0, 1 and 2)

Three members of the A- site doped Nb perovskites with general formula Sr3NbO5.5, BaSr2NbO5.5 and Ba2SrNbO5.5 were synthesised by solid-state methods and their removal efficiency of Methyl violet from aqueous solutions investigated. The X-ray diffraction measurements demonstrated that the three samples have a faced cubic perovskite-type structure in space group Fm m. The addition of Ba2+ into the A-site of Sr3NbO5.5 has influenced the cell volume, crystal size and density. Subsequently, the removal capacity was also impacted. The crystallite size of the oxides was determined to be less than 82 nm. The maximum removal capacities of Methyl violet are found to be 46.5, 13.1 and 8.0 mg/g using Ba2SrNbO5.5, BaSr2NbO5.5 and Sr3NbO5.5 respectively. The amounts of the dye adsorbed by the oxides have increased as the Ba2+ content increased. The removals of Methyl violet have positive relationship with pH, temperature and the mass of the oxides.

Bioremoval of Zinc Using the Tomato Plant, Lycopersicon esculentum

Effluents discharged from various industries contain heavy metals. They reach the environment and affect the quality of air, water and soil. Though they are needed in trace quantities for living organisms, they become toxic when they exceed the threshold concentrations. Hence the present study has been designed to test the efficiency of Lycopersicon esculentum in removing zinc from soil. The tomato plants were grown in soil applied with 100, 200, 300, 400 and 500ppm of zinc sulphate for 60 days. Every fortnight, soil samples were taken and analysed for the levels of Cu, Zn, Fe and Mn. Percent removal of zinc by the plant was calculated from the residual concentration. More removal was noticed in higher concentrations of zinc. After 60 days of treatment, levels of Cu, Zn, Fe and Mn were analysed in the above ground and below ground parts of the tomato plant. Zinc level was 90 ppm in both cases and the same in plants grown in all the concentrations of zinc sulphate. Fluctuations in chlorophyll content were noticed while decline was observed in microbial colonies. The data were subjected to two way analysis of variance and the results are discussed.

Histologic and Histomorphometric Evaluation of Implant Osseointegration of a Dental Implant Three Years in Function Removed Due to Abutment Fracture

For the edentulous patient, dental implant therapy is the accepted treatment to replace one or more missing teeth as implant survival rates are greater than 90%. Unfortunately, surgical removal of dental implants occurs for a variety of reasons. As human studies are limited, this case report provides an opportunity to evaluate the peri-implant characteristics in a dental implant removed from a patient using histology. In our patient, the implant was removed three years after completion of the prosthetic phase due to fracture of the abutment that could not be removed from the implant. Histological examination of the implant revealed mature lamellar bone in direct contact with the implant surface. Histomorphometric evaluation revealed a bone-to-implant contact (BIC) of 73.6%.

Risk Factors and Control Strategies for Cattle Tick Infestations in Nigeria: Influence of Acaricide Application Methods, Hand-Picking Frequency, and Herd Mobility in Plateau State

Background Tick infestations severely impair cattle health and productivity in Nigeria through blood loss, hide damage, and transmission of tick-borne pathogens. Objective This study assessed key risk factors influencing tick infestation and evaluated control methods among Fulani pastoral herds in Plateau State. Methods A cross-sectional survey involving 250 cattle from ten herds was conducted across five Local Government Areas. Tick burden was analyzed against acaricide application methods (pour-on vs. hand-spray), hand-picking frequency, and herd mobility (sedentary vs. migratory). Data were collected via owner interviews and manual tick counts. Statistical analyses were performed using generalized linear models in R software. Results Cattle treated with pour-on acaricides had significantly lower tick burdens compared to those treated via hand-spray (P<0.05). Herds that practiced hand-picking five times weekly had fewer ticks than those hand-picking thrice weekly (P<0.01). Migratory herds recorded significantly lower infestations than sedentary herds (P<0.05). Conclusion Effective tick control requires the integration of optimized acaricide application, frequent manual removaland consideration of herd mobility patterns. Education, capacity building, and policy support are necessary to enhance adoption of effective tick control measures among pastoralists.

Correlation Between Biochemical Oxygen Demand And Chemical Oxygen Demand, At High Salinity Bioreactor-Based, Wastewater Treatment Plant In Al-Hasa Saudi Arabia.

This study aims to determine an empirical relationship between the biological and chemical oxygen demands of industrial effluent running through the membrane bio reactor-based Al-Hasa common industrial wastewater treatment Plant. The relationship between these two parameters was investigated over one month (NOV– 2021 to OCT-2022). The values of R² show that its impossible to predict the result of BOD5 based on COD, however the result of r in AUG month shows a strong relation between them. The average biodegradability index over the one year is less than 0.6, showing that effluent is highly polluted, and biodegradation will not proceed. The plant’s performance in terms of BOD5 and COD removal was very poor over the whole year, however, the months AUG, SEP and OCT months shows a satisfactory performance, this is because a large amount of Industrial wastewater entering the plant contains both organic and inorganic components.

A case of delayed allergy after cyanoacrylate closure of varicose veins, diagnosed by drug-induced lymphocyte stimulation test

Objectives The number of cases of cyanoacrylate closure (CAC) system for varicose veins has been increasing worldwide. However, as this is a new treatment method, the potential adverse effects and other details remain unclear. In particular, the cause of inflammation in embolized veins is still under debate. Methods We performed a drug-induced lymphocyte stimulation test (DLST) on a patient with allergic-like symptoms after CAC.  Results The DLST was strongly positive in this case, and the patient underwent total removal of the CAC-filled vein due to difficulty controlling the symptoms with medication. After that the state was recovered and no medication was continued. Conclusion We encountered a case that a delayed allergy by CA after CAC treatment developed in, eventually leading to the total removal of the CA-filled vein. It was suggested that with doubting allergic-like symptom after CAC, DLST for CA could show not only the diagnosis of the delayed allergy to CA, but also the later treatment policy with stimulation index (S.I.) in the positive cases.

Evaluation Of Physicochemical Separation Characteristics of Pig Manure According to the Type of Solid-Liquid Separator Processes

Objectives The solid-liquid separation (SLS) process generally separates solid and liquid fractions in wastewater and livestock manure. The solid-liquid separation process is an essential pretreatment step for the recycling and purification of pig manure. This study has assessed the separation and/or reduction efficiency by various SLS processes used in pig farms. Methods Seven types of SLS processes (centrifuge, centrifuge (+coagulation agent), belt press (+ coagulation agent), drum screen, inclined screen, vibration screen, and screw press) were used on 11 pig farms and conducted a comparative analysis. As for the sample in this study, the pig raw manure before treatment, the separated liquid and solid manure after treatment of the SLS process collected, respectively. These samples were provided for pH, EC(electrical conductivity) moisture content, CODMn, BOD5, TN, TP, K, TS, SS, NaCl, and heavy metals analysis. Results and Discussion The belt press (+coagulation agent) process had the highest TS and SS reduction rate of 78.8% and 96.9%, respectively. The highest removal efficiency of TN and TP was41.0% and 94.2% by belt press (+coagulation agent) and centrifuge (+coagulation agent),respectively. The belt press (+coagulation agent) removed 59.4% and 66.0% of BOD5 and CODMn,respectively. The Zn and Cu were removed 100% and 98.6% by centrifuge (+coagulation agent).However, the drum screen, inclined screen, vibration screen, screw press, and centrifuge showed lower removal efficiency of nutrient contents, solids, Zn, and Cu than centrifugal and belt press processes with chemical coagulation. Conclusions The centrifugal and belt press separation processes that used chemical coagulation showed much more removal efficiency of nutrient contents, solids, and metals like Zn and Cu. Although SLS with chemical coagulants is an effective pre-treatment process for liquid manure treatment and helps removal effect for suspended solids, nutrients, and heavy metals, further studies are needed on how it affects biological or chemical processing processes that are linked.

A Case of an Orbitocranial Injury with an Unusual Foreign Object

Introduction Large impaled object in the orbital region causes severe visual impact and requires specialized care within the shortest time possible. Objectives In this case report, we discussed the approach and management of a patient that presented with a penetrating orbitocranial injury, from management at the emergency unit, diagnostic imaging, referral to other subspecialty, surgical and medical intervention, and post-operative care. Discussion A 36-year old male had an impaled toilet brush on the supero-nasal aspect of the right orbit, with visual acuity of 6/60 and lacerated upper eyelid. The globe had minimal movement on all gazes, but pupil was reactive to light with no afferent defect. On plain cranial and orbital CT-scan, the foreign body entered the anterior and medial aspects of the right orbit penetrating the right superior orbital wall, right medial lamina papyracea, and the lateral and inferior border of the right frontal sinus with its distal tip at the intracranial region at the right frontal lobe compressing the medial rectus along its tract. Two hours after injury, patient underwent wound exploration, removal of foreign body, repair of eyelid laceration, right craniotomy, frontal contussectomy, duraplasty, and JP-drain insertion under general anesthesia. Intraoperatively, there was note of transected canaliculus and avulsed conjunctiva. The medial rectus was intact and attached. The frontal lobe was contused with embedded fragments of right posterior orbital bone with 3cm opening on the dura.  Post-operatively, Fluconazole was added to the medications after culture results of the toilet brush tip tested positive for fungal elements. Patient was discharged after 21 days with visual acuity of 6/6 on both eyes and improved ocular movement.  Conclusion These types of injury warrants thorough and systematic history taking and physical examination, acquiring pertinent imaging modalities to better visualize the extent of injury, and execute surgical and medical intervention that is multidisciplinary.

Breast Implant-Associated Anaplastic Large Cell Lymphoma: A Case Report

Breast implant-associated anaplastic large cell lymphoma (ALCL) is a recently recognized type of T-cell lymphoma that can develop following breast implants, with morphologic and immunophenotypic features indistinguishable from those of ALK-negative ALCL. Here we report a case of a 58-year-old woman with a history of subglandular silicone implants placed for bilateral breast augmentation 25 years ago, who presented with bilateral breast pain and was found to have bilateral Baker Grade III capsular contracture, and heterogenous fluid collection centered near the left third costochondral articulation, a suspicious left chest wall lesion, and left axillary lymphadenopathy on imaging. A left axillary lymph node core biopsy and an aspiration of the fluid were performed, and no malignant cells were identified. The patient underwent bilateral removal of breast implants and total capsulectomies. Microscopic examination of the capsule surrounding the left breast implant revealed large pleomorphic tumor cells in a fibrinous exudate. By immunohistochemistry, the tumor cells were found to be positive for CD3 (subset), CD4, CD7, CD30 (strong and uniform), and CD43, and negative for CD2, CD5, CD8, and ALK1, supporting the diagnosis of breast implant-associated ALCL. No lymphoma cells were identified in the right breast capsule, confirmed by CD30 stain. Breast implant-associated ALCL is a very rare disease that can develop many years after breast implant placement. Proper evaluation with breast imaging and pathologic workup is essential to confirm the diagnosis in suspected cases. Our case highlights that adequate sampling is important in the investigation of patients with suspected breast implant-associated ALCL.

Biosorption of Lead Using the Bacterial Strain, Bacillus subtilis (MTCC 2423)

Lead removal efficiency of the bacterial strain, Bacillus subtilis (MTCC 2423) was tested with 200, 400, 600, 800 and 1000 ppm of lead in minimal broth for a period of ten days. Samples were tested for the level of lead every two days in each concentration and maximum removal was observed after six days of treatment. With the increase in lead concentration, both biomass and lead removal efficiency showed an increase. When tested with immobilized, dead and live cells, maximum removal was observed for immobilized cells. Among the sugars tested, monosaccharide sugars enhanced the biomass of B. subtilis during lead treatment and the results are discussed.

Outcome and SD-OCT Macular Findings Following Surgery in Spared Macula Giant Retinal Tear Retinal Detachment.

Purpose To study outcome and spectral domain optical coherence tomography (SD-OCT) macular findings in patients who underwent surgery for spared macula giant retinal tear (GRT) retinal detachment. Methods a retrospective study of 12 patients with spared macula giant retinal tear (GRT) retinal detachment who underwent vitrectomy (N=7), vitrectomy with an encircling scleral buckle (n=4) and scleral buckle (n=1) with at least 3 months follow up after silicon oil removal (SOR) . Post-SOR macular SD-OCT scans were studied in all eyes. Results Final reattachment achieved in all eyes with single primary surgery. Post-SOR SD-OCT macular finding was photoreceptors layer disruption in 6 eyes, epiretinal membrane (ERM) in 4 eyes, Macular hole in 1 eye and choroidal neovascularisation in 1 eye. Significant correlation found between final Best-Corrected Visual Acuity (BCVA) and macular pathology on SD-OCT p value (0.048). Conclusion SD-OCT plays a high role in diagnosis of macular alterations that can be associated with poor functional outcome in anatomically successful GRT surgery with spared macula pre-operatively.

The use of Dermacell® in Fingertip Injury

Matrices or tissue scaffolds provide a collagen structure for tissue remodelling while the removal of viable cells aims to minimize or prevent inflammatory or immunogenic response. Allograft collagen scaffold can support the patient’s own cellular ingrowth, ingeneered to minimize an immune response and to yeld a bio-compatible matrix and support incoming cellular growth. The decellyularized dermis retains its growth factors, native collagen scaffold, and elastin, thanks to a LifeNet Health proprietaryprocessin technology.

Porphyromonas Gingivalis Response to Ultrasonication

Introduction Ultrasound technology has previously been applied for cataract removal and tennis elbow treatment. Recent data supports the use of ultrasonic debridement in the treatment of diabetic foot ulcers. No data is available concerning the potential antibacterial properties of a clinical grade, lower energy ultrasound probe. We investigated the effect of a ultrasonic probe with respect to P gingivalis bacterial viability. Methods A Tenex Tx1 probe with standard settings for clinical use was used for this study. A Gram negative (Porphyromonasgingivalis) bacteria, known for its pathological activity, was investigated. The bacteria was cultured in an anaerobic broth, re-suspended to achieve a consistent bacterial count, and 5ml of this re-suspension was placed in a test tube for testing. Each tube was sonicated with the Tx1 probe for varying lengths of time (10, 30, 60, 120 seconds). The sonicated was diluted and plated on blood-agar plates, followed by incubation for 48 hours at 37°C in an anaerobic growth chamber. The number of colony forming units were counted, on each plate and the anti-bacterial effect was calculated. A one way analysis of variance was performed for statistical analysis. Results A significant time-dependent antibacterial effect was demonstrated with sonication. When comparing the kill rate between the control and 120 seconds of sonication P Gingivalis had a 64% kill rate. This was the only statistically significant time comparison achieved, although the trend for all the time intervals was a reduction in the colony forming unit counts. Conclusion This study demonstrates that a clinically available ultrasonic probe (Tenex Tx1) has an antibacterial effect against the gram negative anaerobic bacterial species P gingivalis. Complete deactivation was not achieved, and there was a variation in effect dependent on the time of active sonication, with greater sonication times leading to greater kill rates. This data may partially help to explain the ability for ultrasonic debridement to result in the healing of long standing diabetic ulcers, that have been recalcitrant to other forms of treatment.

Essential Oils from Plants

Essential oils, called volatile oils or ethereal oils, are natural metabolic secretions of plants, the role of which is not yet fully understood by science. Some specialists consider them to be true plant hormones, fluid manifestations of the immune system of plants, in the sense that they contribute to the removal of pests, attracting, instead, pollinating agents, which are some insects and birds. Small, light–colored spherical structures, is, in fact, modified filaments, which behave like some secretory glands of essential volatile oils. They are the ones who give the fragrance of the aromatic plant and have, in the case of salvation, medicinal curative properties, such as fever reduction, blood cleansing, and relieving pain. Essential oils are products isolated from plants or organs through a physical process that have a certain volatility (higher or lower) and possesses an agreeable odour characteristic of the source from which they originate. They are also known as volatile or essential oils and their name are usually given by the popular name of the plant from which they are extracted. The most important characteristic of these mixtures, which also gives the special economic value, is the specific smell. This is the basis for their use in perfumery, cosmetics and the food industry. Many essential oils have special therapeutic qualities, some of which have been known and used since antiquity. 

Volvulus of the Small Bowel Due to Malrotation During Pregnancy: A Case-Report

Volvulus occurring during pregnancy is a rare complication, still potentially lethal nowadays for both the mother and child due to several, early arising complications. We report here a case of small bowel volvulus in a 28 weeks and 4 days, 29 years-old, pregnant woman with a past medical history of appendectomy in her childhood. Patient presented in emergency department with abdominal pain and abnormal hepatic tests. Cholangio-MRI suggested bowel obstruction due to volvulus that was confirmed by gastroscopy (showing the obstruction) and intestinal MRI. Patient was first treated by laparoscopy but, due to a very complicated abdominal status with the presence of several adhesions of the small bowel, surgery was changed to an open laparotomy, which allowed discovery and repositioning of small bowel malrotation and removal of adhesions. Both patient and the foetus were healthy after surgery and the patient was then discharged. In the light of this particularly rare case of small bowel volvulus due to malrotion, we will describe the pathology of bowel obstruction and more particularly volvulus during pregnancy and discuss its diagnosis and treatment.

Atypical Patterns of Constrictive Pericarditis after Heart Transplantation: A Case Report

Constrictive pericarditis (CP) represents a rare complication after heart transplantation (HTx), resulting from various postoperative events such as mediastinitis, pericardial effusion, or allograft rejection. We describe our recent experience with managing an HTx recipient who developed atypical patterns of CP predominantly involving the right ventricle. A 52-year-old male who had received heart transplantation 2.5 years before was admitted to our institution because of progressive symptoms of heart failure. The patient had experienced acute rejection twice post-HTx, both with International Society for Heart and Lung Transplantation grade 1R, undergoing an additional endomyocardial biopsy other than those performed during regular check-ups. On admission, echocardiography revealed paradoxical septal motion and a large cystic-like mass with a thick capsule in front of the right ventricle. Right heart catheterization revealed elevation of right atrial pressure, with severely reduced cardiac index. Magnetic resonance imaging revealed both seroma and a thick cystic-like capsule tightly adhered to the right ventricle. CP was suspected despite the atypical patterns of presentation. Seroma was removed through exploratory lateral thoracotomy, without improvement in symptoms, which was only achieved via subsequent pericardiectomy involving resection of the thickened parietal pericardium, removal of effusion fluid, and further excision of diffusely thickened visceral pericardium and epicardium. The patient is currently recovering uneventfully. The possibility of CP after HTx should be considered despite the rarity of this condition and HTx recipients should be closely monitored using various imaging modalities because CP typically demonstrates non-specific symptoms and physical findings of heart failure, with high mortality.

Compliance to Company Based Colorectal Cancer Screening in Germany using Fecal Immunochemical Test (FIT) - Results of Almost Half a Million FIT Tests

Background Despite the existence of the statutory early cancer detection program in Germany and the removal of financial barriers, which is frequently reported in the literature to be the main obstacle in screening, uptake of colorectal cancer screening remains quite low. The campaign for colorectal cancer screening in German companies reported in this article started in 2010. It was initiated because of the low compliance with opportunistic public colorectal cancer screening efforts. Its goal is to improve participation by offering an organized screening program using a simple test (FIT). Methods An offer for company employees is publicized through posters, company newsletters and the intranet. The difference between the positivity rates of those who returned the kits within 20 days and later than 20 days was assessed using the Z-test. The average time between a positive result and colonoscopy was estimated using the Poincaré plot method. The positive predictive values were calculated for carcinomas, advanced adenomas or any lesions. The sensitivity and specificity of immoCare-C published by Vogel et al. and Hundt et al. were used to derive the confidence intervals for the positive likelihood ratio (for carcinoma and any kind of adenoma). Results A total of 312,147 kits were returned and analyzed (return rate 70.2%). 5.6% gave a positive result. The PPV for cancer aged between 55 and 74 was 4.6% for men and women (95% CI: 2.38%-6.76% and 1.28%-7.99%, respectively), but 22% for men (95% CI: 17.93%-26.65%) and 8% for women (95%CI: 3.63%-12.26%) for advanced adenomas. The PPV for any lesion was higher for those with familial risk (49.3%) and 42.6% for those without familial risk (95% CI: 40.2%-45.0%), but with overlapping confidence intervals. Conclusions The reported sample is not representative. Although, offering CRC screening in companies may be an effective way of increasing uptake in the target population. Differences in the test performance between men and women need further evaluation.

Repeat Thoraco-Amniotic shunt placement to treat Fetal Pleural Effusion due to Pulmonary Sequestration

We report a twin gestation with one fetus afflicted by a left sided Extra-Lobar Sequestration (ELS) in a morbidly obese mother. The ELS was complicated by a left pleural effusion in the second trimester unresponsive to maternal steroid administration. We discuss the need for repeat shunt placement, in the setting of maternal morbid obesity and twin gestation. Shunt replacement was necessary secondary to dislodgement. Delivery at 34 weeks gestation was followed by successful surgical removal of the ELS. At one year follow up the infant has complete expansion of the left lung with no morbidity.

The Comparison of Functional Outcomes Between Supraglottic Horizontal Laryngectomy and Supracricoid Partial Laryngectomy

Objectives The aim of this study was to compare the functional outcomes (including swallowing, respiration and phonation) of supraglottic horizontal laryngectomy (SGHL) and supracricoid partial laryngectomy (SCPL). Methods The clinical and pathological data were evaluated for 36 previously untreated patients who were diagnosed with laryngeal carcinoma and underwent SGHL or SCPL at the Department of Otorhinolaryngology-Istanbul Training and Research Hospital from 2010 to 2016. Removal of the nasogastric tube, decannulation and hospitalisation times were recorded in both groups and postoperative complications were noted. Results The SGHL group contained 15 patients and the SCPL group contained 21 patients (14 cases of cricohyoidoepiglottopexy (CHEP) and 7 cases of cricohyoidopexy (CHP)). The mean age of the subjects was 57.4 years in the SGHL group, and 59.7 in the SCPL group. Patients in the SGHL group were decannulated after 65.2 days, whereas the average decannulation time was 72.6 days in the SCPL group. This difference in decannulation time between the groups was not statistically significant (p>0.05). The mean hospitalisation time was 23 days, with no statistically significant difference between the groups (>0.05). The nasogastric tube was removed from the patients after 37.9 days in the SGHL group and after 35.8 days in the SCPL group. No statistically significant difference was determined in the time to start feeding between the groups (p>0.05). Surgical wound infection, the occurrence of pharyngo-cutaneous fistulas and rupture of the pexy sutures were complications. Conclusion Functional outcomes of SCPL were similar to those of patients who underwent SGHL. The preservation of the hyoid bone is the most important consideration for preserving the swallowing function.

Peripheral Cemento Ossifying Fibroma – A Case Report

Introduction: Cemento-ossifying fibroma is is a reactive lesion arising from the soft tissues (gingiva). Case report: A 13-year-old boy presented with the complaint of lump in mandibular right posterior region on the lingual side since a month. The patient presented no symptoms and had no medical history of interest. The lesion was excised and submitted for histopathological evaluation, which gave a diagnosis of peripheral cemento-ossifying fibroma. Discussion: Periheral Cemento-ossifying fibromas are slow-growing lesions, and are more frequent in women between the second and third decades of life. Although the underlying cause is not known, there have been reports of the lesion developing after irritation/ trauma in the concerned area. Due to the good delimitation of the tumor, surgical removal and curettage is the treatment of choice.

Bedside Lung Ultrasound in the Assessment of Volume Status in Chronic Hemodialysis Patients

Introduction: Sonographic B-lines, also known as lung comets, have been shown to correlate with the presence of extravascular lung water. The aim of this study is to assess if chest ultrasound could detect lung water imbibition and its variations induced by dialysis, an experimental model of controlled rapid fluid loss. Methods: A cross-sectional study was conducted in a hemodialysis center in the city of Fez. Lung ultrasounds, impedance measurement, and ultrasound of the inferior vena cava were achieved 30-60 minutes before and after the hemodialysis session. Results: The values, measured by the different techniques used, decrease significantly after hemodialysis (p <0.001). The values studied before and after the hemodialysis, had shown a significant correlation between the results of the impedance measurement, lung ultrasound, and the maximum and minimum of the VCI index diameter and its collapsibility. The decrease in B-lines was correlated with weight decrease during dialysis (p0.005); none of the parameters concerning the IVC were correlated with fluid removal. Conclusion: ultrasound performed at the bedside is now emerging as a reliable, easy-to-apply, and safe method for measuring both lung water and intravascular overload and their decrease after dialysis even on asymptomatic patients. These observations strongly support the use of lung ultrasound in estimating volume overload and monitoring the response to therapy in hemodialysis patients.

Broken Endodontic Instrument Caused Inferior Alveolar Nerve Paraesthesia: A Case Report.

A healthy 55-year-old man was referred to the Department of Endodontics, Oral and Dental Healthy Hospital, Eskişehir suffering from pain and paraesthesia in the left lower lip and chin.A panoramic radiograph revealed the presence of broken endodontic instrument beyond the apex of the mandibular left third molar. A cone beam computed tomography (CBCT) examination was undertaken, which revealed that the broken instrument was inside the mandibular canal. Damage to the inferior alveolar nerve (IAN) secondary to extrusion of a broken endodontic instrument was diagnosed. Extraction of the tooth was decided and the patient was prescribed with 1 mg/kg/day prednisone 2 times/day, once-daily regimen, and 150 mg/day pregabalin, two doses per day, monitoring the progress with periodic follow-up visits. One month after the incident, the signs and symptoms were gone. The complete resolution of the paraesthesia and the control of pain achieved in the present case suggest that surgical removal of broken endodontic instrument extruded into the mandibular canal with the use of prednisone and pregabalin is a good option in the management of inferior alveolar nerve injury.
