Patient-specific PEEK implants for immediate restoration of temporal fossa after maxillary reconstruction with temporalis muscle flap / 대한악안면성형재건외과학회지

Background@#Temporal hollowing is a common complication following the rotation of the temporalis muscle that leaves the patient with a cosmetic impairment. Several alloplastic materials have been used to reconstruct the donor site; however, these implants need meticulous adaptation to conform the periphery of the defect and restore the contour of the temporal area. The aim of this study was to assess the use of patient-specific polyetheretherketone (PEEK) temporal implants to prevent temporal hollowing following the use of full temporalis muscle flap for large maxillary defects reconstruction. @*Methods@#This was a prospective study conducted on eight patients with major maxillary defects indicating the need of reconstruction with full temporalis muscle flap or any lesion indicating major maxillary resection and immediate reconstruction with total temporalis muscle flap. For each patient, a patient-specific PEEK implant was fabricated using virtual planning and milled from PEEK blocks. In the surgical theater, the temporalis muscle was exposed, elevated, and transferred to the maxilla. After the temporalis muscle transfer, PEEK implants were fixed in place to prevent temporal hollowing. @*Results@#The surgical procedures were uneventful for all patients. The esthetic result was satisfactory with no post-operative complications except in one patient where seroma occurred after 2 weeks and resolved after serial aspiration. @*Conclusion@#Patient-specific PEEK implant appears to facilitate the surgical procedures eliminate several meticulous steps that are mainly based on the surgeon’s experience.

Effect of Muscle Energy Technique on Pain Perception and Functional Disability of Women with Postnatal Low Back Pain.

Aims: To determine the effect of muscle energy technique (MET) on postnatal low back pain. Place and Duration of Study: Department of obstetrics and gynecology, Ain Shams University Hospital, and Outpatient Clinic of Faculty of Physical Therapy, Cairo University, between January and May 2013. Methodology: This study was carried out upon forty women diagnosed as postnatal low back pain. They were selected from outpatient clinics of gynecology of Ain Shams University Hospital, Cairo University. Their age ranged from 25-35 years, BMI<30kg/ m², they were all after normal vaginal delivery using local anaesthesia. Patients with radicular pain distal to the knee, previous low back surgery, low back pathology diagnosed by a physician, spondylolisthesis and chronic low back pain were excluded from the study. They were randomly assigned into two equal groups (A& B). Group (A) consisted of twenty subjects, with an average age 29.2±1.9Yrs, and BMI 27.28±2.1kg/m2 who received MET. Group (B) consisted of twenty patients, with an average age 28.58±2.2Yrs, and BMI 28.92±0.7kg/m2 who received sham technique. A hot pack was used for 15 minutes for both groups (A&B) before the treatment. This is to decrease pain, muscle spasm, and provide vasodilatation of the blood vessels supplying the area. The MET was applied three times per week for four weeks for patients in group A, and the sham technique was applied three times per week for four weeks for subjects of group (B). Assessment of all subjects in both groups (A&B) was carried out before and after the treatment program using Visual Analogue Scale (VAS) and Stratford Back Pain Functional Scale (BPFS). Results: There was a statistically highly significant decrease (P<0.001) in VAS scores and a statistically highly significant increase (P<0.001) in BPFS, after 4 weeks of the treatment program for group A than group B. Conclusion: Muscle energy technique is an effective and safe method in alleviating postnatal low back pain.

Antioxidant constituents from Solenostemma argel [Del.] Hayne

The phytochemical investigation of the aerial parts of Solenostemma argel [Del.] Hayne revealed the presence of two compounds in its petroleum ether extract viz., lupeol [1] and beta-sitosterol [2]. The chloroformic extract contains beta-sitosterol-3-O-beta-D-glucoside [3] and luteolin [4]. Three more flavonoid compounds were isolated from the ethyl acetate extract viz. kaempferol-3-O-beta-D-glucoside [5], quercetin-3-O-beta-D-glucoside [6] and kaempferol-3-O-neohesperidoside [7]. These isolates were fully identified using different physical [mp., Rf] and spectral tools viz. UV, IR. [1]H- and [13]C-NMR experiments as well as mass spectral techniques viz. DCI-. El- and FAB-MS. The anti-microbial evaluation of the isolated substances was demonstrated against certain gram positive, gram negative bacterial strains and fungi, and the anti-oxidant activity was also performed
