It is a retrospective analysis of cases of endoscopic Dacryocystorhinostomy (DCR) in whom stents were not inserted after completion of surgery for the last 2 years. Thirty-five patients were included in this study, and selection of patients was done depending on both clinical findings preoperatively and on the operative findings during surgery. These criteria ensure that the level of obstruction is postsaccal, and good surgical procedure with maximal sac exposure and marsupialization. When all criteria were present, stents were not inserted. Follow-ups range from 6 to 12 months (average of 8 months). Success was determined by symptomatic relief of epiphora and dacryocystitis, together with the endoscopic findings of free passage of the fluorescein dye that is applied to the conjunctiva to the nasal cavity. In this study, all the patients had both symptomatic and clinical improvements making the success rate 100%. As a conclusion, stents are not always necessary after endoscopic DCR. © 2011 Springer-Verlag.

The present study reports the production of mustard seed oil ethyl esters (MSOEE) through alkali-catalyzed transesterification with ethanol using potassium hydroxide as a catalyst. The influence of the process parameters such as catalyst concentration, ethanol to oil molar ratio, reaction temperature, reaction duration and the catalyst type was investigated so as to find out the optimal conditions for the transesterification process. As a result, optimum conditions for production of MSOEE were found to be: 0.90% KOH wt/wt of oil, 8:1 ethanol to oil molar ratio, a reaction temperature of 60 C, and a reaction time of 60 min. Dry washing method with (2.50% wt.) of the activated carbon that was produced from the de-oiled cake was used to purify the crude ethyl ester from the residual catalyst and glycerol. The transesterification process provided a yield of 94% w/w of ethyl esters with an ester content of 98.22% wt. under the optimum conditions. Properties of the produced ethyl esters satisfied the specifications prescribed by the ASTM standards. Blending MSOEE with petro diesel was also investigated. The results showed that the ethyl esters had a slight influence on the properties of petro diesel. © 2013 Elsevier Ltd. All rights reserved.

A simple technique for obtaining wide-angular nulling in the sum and difference patterns of the monopulse antenna is presented. This technique involves the addition of two elements, one at each end of the monopulse antenna array, which together produce a cosine pattern used for obtaining wide-angular nulls. By adjusting the amplitude of the excitation of the two-element auxiliary array, it is possible to modify the overall array pattern to place wide angular nulls in the directions of undesired interference signals. © 2002-2011 IEEE.

Purpose: The purpose of the present study was to compare the effect of submucosal versus intramuscular administration of dexamethasone sodium phosphate on patients' quality of life after surgical removal of impacted lower third molars. Patients and Methods: A randomized, non-blind, clinical trial was planned. The sample was composed of patients requiring extraction under local anesthesia of a single partial bony impacted mandibular third molar with Class II or III and position B or C, according to the Pell and Gregory classification. The patients were randomly distributed into 1 of 3 groups: submucosal dexamethasone, intramuscular dexamethasone, and a control group that received no steroid. A modified translated questionnaire was used to assess the patients' perception regarding different quality of life dimensions. In addition, the objective measurements of facial pain, swelling, and trismus were performed on days 1, 3, and 7 postoperatively. Results: A total of 33 subjects requiring surgical removal of a single impacted mandibular third molar under local anesthesia were included in the present study. Both dexamethasone groups showed a significant reduction in swelling and pain compared with the control group at all intervals (P <.05). Submucosal dexamethasone provided significant improvement in trismus compared with the control group on day 1 postoperatively (P =.026). Both dexamethasone groups showed a highly significant difference in the effect on quality of life and the duration of effect in all subscale scores (P <.01) except for the "speech" and "appearance" subscales. The effect was comparable between the 2 treated groups in all parameters. The effect of the 2 routes of dexamethasone was also comparable for all parameters. Conclusions: Submucosal injection of dexamethasone 4 mg is an effective therapeutic strategy for improving the quality of life after surgical removal of impacted lower third molars with a comparable effect on postoperative sequelae to intramuscular injection. It offers a simple, safe, painless, noninvasive, and cost effective therapeutic option for moderate and severe cases. © 2011 American Association of Oral and Maxillofacial Surgeons.

Burns | Year: 2013

Background Marjolin's ulcer, a term used to describe a malignancy arising in chronic ulcers of the skin, sinuses, scar tissue, and especially burns scars. The majority of burn scar carcinomas are seen after a lag period in burns that were not grafted following injury. Objective To describe the epidemiology and its clinical characteristics of patients with Marjolin's ulcer arising in a chronic burn scar. Design and patients A case series study was done at Al-Jumhoori Teaching Hospital Burn Center, identifying 27 patients with chronic burn scar that underwent malignant transformation into a carcinoma, from January 1992 to December 2011. Data related to patients were retrieved from their medical records. All lesions were secondary to burns from various causes. All patients were proven to have malignancy by biopsy. Results Of the 27 Marjolin's ulcer patients, 18 were males and 9 were female (male to female ratio 2:1), and the mean age was 42.7 years (range: 18-80 years). Upon histological examination, all were diagnosed as well-differentiated squamous cell carcinoma. The lower limb was most frequently affected (81.5%). Treatment of the neoplasm consisted of excision and grafting in 81.5%, radiotherapy in 11.1% and amputation in 7.4%. Local recurrence was noted in 22.2%, and lymph node metastasis in 11.1%. Conclusion Chronic ulcer that undergoes malignant change was a common finding in the present study. All suspected masses or ulcers within chronic burn scars should be promptly biopsied. © 2013 Published by Elsevier Ltd and ISBI.

Botulinum toxin (BTX) is a bacterial toxin that could be used as a medicine. Clinical applications of BTX have been expanding over the last 30 years and novel applications reported. Its mechanism of inhibiting acetylcholine release at neuromuscular junctions following local injection is unique for the treatment of facial wrinkles. Other dose-dependent anti-neuroinflammatory effects and vascular modulating properties have extended its spectrum of applications. Conditions such as temporomandibular joint disorders, sialorrhea, headache and neuropathic facial pain, muscle movement disorders, and facial nerve palsy could also be treated with this drug. Further applications of BTX are likely to be developed. This paper reviews the established and emerging applications of BTX in the field of oral and maxillofacial surgery. An overview of the pharmacology, toxicity and preparations of the agent is given. © 2009 International Association of Oral and Maxillofacial Surgeons.

The present work reports the production of biodiesel from Silurus triostegus Heckel fish oil (STFO) through alkaline-catalyzed transesterification by using potassium hydroxide (KOH) as an alkaline catalyst with methanol. Chemical and physical properties of the extracted oil were determined. It was found that STFO has a low acid value (1.90mg KOH/g oil); hence no pre-treatment such as acid esterification is required to produce the biodiesel. The influence of the experimental parameters such as KOH concentration (0.25-1.0% w/w of oil), methanol to oil molar ratio (3:1, 6:1, 9:1 and 12:1), reaction temperature (32, 45 and 60°C), reaction duration (30, 60, 90 and 120min), type of the catalyst (potassium or sodium hydroxide) and step multiplicity (single- and two-step transesterification) on the yield of the biodiesel were investigated. The maximum biodiesel yield (96%) was obtained under the optimized parameters of the transesterification (KOH 0.50% w/w, 6:1 methanol to oil, at 32°C for 60min). The properties of the produced biodiesel were found to conform with the ASTM standard, indicating its suitability for internal combustion engines. Blending of the produced biodiesel with petro diesel with various volume percentages was investigated as well. © 2013 Elsevier Ltd.

Melon seed oil was successfully converted into biodiesel fuels via alkali catalyzed transesterification. Transesterification parameters such as base concentration, methanol to oil molar ratio, reaction time, reaction temperature, catalyst type, and step multiplicity were investigated. The results indicated that (0.75% KOH w/w of oil, a 6: 1 methanol to oil molar ratio, reaction temperature of 60°C, and a duration of 1 h) where the optimal experimental conditions for the transesterification. The Fourier transform infra red spectra of the biodiesel was also specified and found differs greatly from that of the parent oil confirming the formation of biodiesel. Properties of the produced fuels were determined and found enhanced compared to those of the parent oil. Besides, the optimal biodiesel sample was blended with petro diesel in various volume percentages. However, the results showed that biodiesel had slight influence on the original properties of petro diesel. Copyright © 2013 Taylor & Francis Group, LLC.


Purpose To evaluate the efficacy of local anesthesia using tramadol hydrochloride (HCl) with versus without adrenaline in the extraction of upper molar teeth. Patients and Methods This was a double-blinded study that included 100 patients who required extraction of 1 upper molar by the conventional method and were allocated randomly into 1 of 2 groups: in group A (n = 50), each patient received an initial dose of drug A (tramadol HCl 50 mg and adrenalin 0.0225 mg diluted to 1.8 mL by distilled water); in group B (n = 50), each patient received an initial dose of drug B (tramadol HCl 50 mg diluted to 1.8 mL by distilled water). Degree of pain during tooth extraction, duration of surgery, and total number of cartridges used were recorded intraoperatively. Postoperatively, patients were instructed to record any adverse effects, such as nausea or vomiting, on the first day of the operation. Results There were significant differences in the number of cartridges used and the degree of intraoperative pain. However, there was no significant difference in duration of surgery or side effects. Conclusions The results of this study suggest that tramadol HCl in combination with adrenaline can be used as an alternative local anesthetic in oral and maxillofacial surgery when, for some unusual reason, a patient cannot receive a conventional local anesthetic. © 2013 American Association of Oral and Maxillofacial Surgeons.
