A rare presentation of hydatid cyst in abdominal wall: case report

Echinococcus species cause hydatidosis, which is a verminosis. Echinococcus vogeli results in polycystic hydatid disease, and wild dogs are the definitive hosts. In fact, wild dogs and rats are the most common hosts. The transit of Echinococcus eggs through the liver and lungs is hypothesized to result in hydatid cyst formation in the subcutaneous tissue. In 1.5 percent of patients with hydatidosis, hydatid cysts of the subcutaneous tissue have been documented. They ranged from 0.6 percent to 2.6 percent. We here report a case of hydatid cyst of the abdominal wall which was surgically treated. A 30-year-old lady had been experiencing pain associated with lump in her right lower abdomen for three months. On clinical examination, an enlargement in the left side measuring 4 x 3 cm was discovered. Imaging was performed preoperatively to rule out other differential diagnoses. Ultrasound was performed, followed by computed tomography and magnetic resonance imaging, which revealed multilocular cystic mass measuring 9 x 8.5 x 4.7 cm along the right lower anterior abdominal wall muscles (with cysts inside cysts), which suggested hydatid cyst. Histopathology confirmed the diagnosis of hydatid cyst, after the mass was surgically removed. Treatment with albendazole was continued. Hydatid cyst of the subcutaneous tissue is uncommon, with only a few occurrences recorded in the literature. This study describes a case of hydatid cyst in an uncommon place. Imaging confirmed the diagnosis, and the tumour was surgically removed. It ruptured during surgery and was successfully treated with hypertonic saline and albendazole. Then it was adequately managed. Given that subcutaneous hydatid cyst is rare, it's vital to keep in mind that it can be a possible cause of abdominal wall mass. Specific imaging test is essential to correctly locate and remove it. It must be treated with anthelmintic before surgery, in order to reduce the risk of contamination due to cyst rupture during surgery. Subcutaneous hydatid cyst should be considered one of the differential diagnoses for soft tissue masses, in particular in patients living in endemic areas. To rule out alternative possibilities, proper imaging test is essential. The treatment of choice is complete excision

Application and roles of management science tools and techniques to effective decision making in the academic settings

AbstractThe major purpose of the study was to discover to what extent selected educational systems were using specified management science tools and techniques in their decision making processes. The familiarity of the administrators and the employees with such techniques, and which of the models were used the most were also studied. Finally, the purpose of study was to discover economic and managerial benefits provided by using MS. methods. The results indicated that although academic administrators of Southern California universities used management science models and techniques, but the models were used less than industrial and business organizations

Management of Small Urethrocutaneous Fistula by Tight Ligation with Fulguration of the External Epithelium of the Tract

Background/Purpose: Urethrocutaneous fistula (UCF) is the most common reported complication of hypospadias repair. The success of the operative technique is usually measured by its effectiveness in reduction of the incidence of UCF. Materials & Methods: In a prospective study, 11 patients with 12 small caliber fistulae were included. After identifying the fistulous opening, the fistula tract was circumferentially and meticulously dissected ,then the dissected tract was lifted up and the base was ligated tightly with 5/0 vicryl, the external epithelium of the dissected tract was fulgurated with the diathermy, then a second layer of local soft tissue was secured over the ligated fistula with 6/0 vicryl, followed by overlapping skin closure over the ligated stump with 5/0 vicryl rapid . Dressing with fucidin -tull and pressure dressing was applied to be removed after 24h with removal of the urethral catheter. Meatal stenosis and urethral stricture distal to the fistula was excluded in all the patients, except in one patient who was having meatal stenosis who had meatoplasty in the same time. Results: All fistulae healed nicely with no recurrence over 6 months follow up period. Conclusion: tight ligation of the UCF with fulguration of the epithelium of its tract is effective and successful in treating the small caliber UCF. It is non-time consuming, and not associated with any urethral stenosis or obstruction at the site of the ligated fistula.Index Word: Penile fistula, urethra-cutaneous fistula, ligation, hypospadias

Oral Squamous Cell Carcinoma Associated with a Dental Implant: a case report and literature review

Objectives: Prosthodontic rehabilitation using dental implants has become a common practice in dentistry at the present time. Although severe complications related to dental osseointegrated implants are uncommon, in recent years several cases of oral squamous cell carcinoma adjacent to dental implants have been published. Study Design: A 67-year-old edentulous woman developed an oral squamous cell carcinoma around right mandibular implant about 12 months after receiving dental implants. The treatments involve chemotherapy, explantation of the implants and radiotherapy. Result and Conclusions: The use of endosseous implants has been associated with a low risk for the development of cancer. However, this case report serves as evidence to the importance of careful screening at routine dental examinations especially if the patient suffers from peri-implantitis, any mucosal erosion or discoloration, leukoplakia around implant, pain, implant loosening, bone loss around implant, mucosal erythema, and soft tissue inflammation

Multifocal Primary Non- Hodgkin’s Lymphoma of the Oral Cavity: Report of Three Cases and Review of the Literature

Objective: Oral non- Hodgkin’s lymphoma (NHL) is a relatively rare neoplasm that may develop in the soft tissues or jaw bones, with or without node or marrow involvement. Oral lymphomas  are often difficult to diagnose as there are no characteristic clinical features and usually appear as non- tender swellings.Case: We describe clinical, radiographic, histopathological and immunohistochemical findings of three cases of multifocal NHLs presenting in the oral cavity.Conclusion: If the oral lesion is multifocal, extra nodal lymphoma must be considered in the differential diagnosis

Fabrication of chelating diethylenetriaminated pan micro and nano fibers for heavy metal removal

In this study, commercial acrylic fibers were modified with diethylenetriamine to prepare metal chelating fibers. The effects of process parameters on the efficiency of the reaction were investigated. FTIR spectroscopy and TGA analysis were used to confirm the chemical changes made to the fibers during the reaction. The ability of the modified fibers for removal of Pb (II), Cu (II) and Ce (IV) ions from aqueous media was determined. The modified fibers showed a slight decrease in mechanical properties compared to raw ones. Furthermore, the acrylic micro fibers were electrospun to nanofibers and the ability of modified nanofibers for the adsorption of the metal ions was studied

Effect of Sprinkler Type and Tillage Practice on a Soil Infiltration Parameter Under a Moving Sprinkler Irrigation Machine

A modified Green-Ampt infiltration model was used to determine soil hydraulic conductivity values from surface runoff and sprinkler application data sets. Comparison of three sprinklers and two secondary tillage practices over three irrigation seasons were made to identify the effect of these factors on hydraulic conductivity. Hydraulic conductivity values were different for the low, medium and high-pressure sprinklers used in the study with the hydraulic conductivity values varying inversely with the pressure. Hydraulic conductivities also varied among the years of the study. A ripping (subsoiling) secondary tillage practice increased hydraulic conductivity by the 66 percent when compared with a control practice. Hydraulic conductivities generally decreased during the irrigation season. A calibrated infiltration model was used to predict the surface runoff values for irrigation application depths not used in the data sets
