Abstract A combination of peripheral blood mesenchymal stem cells (PBMSCs) and platelet rich fibrin matrix (PRFM) could be a probable periodontal regenerative material with the synergy of the added benefits of each material. Objective This randomized controlled clinical trial aimed to evaluate the regenerative capacity of supercell (PRFM and PBMSCs) compared with that of PRFM alone in human periodontal mandibular intraosseous defects (IOD). Methodology This study included 17 patients of both sexes (12 men, 5 women) aged 30-55 years (mean age = 37.7±4.4 years) who fulfilled the inclusion criteria (radiographic and clinical evaluation for bilateral IOD with probing pocket depth (PPD ≥ 6 mm). A split-mouth design was used in each patient. A total of 34 sites in the mandibular arch randomly received PRFM alone + open flap debridement (OFD) [Control sites] or supercell (PRFM+PBMSCs) + OFD [Test sites]. The clinical parameters plaque index (PI), gingival index (GI), PPD, clinical attachment level (CAL), and in the radiographic parameters; defect depth (DD) and defect fill percentage (DFP) were recorded at baseline, 3 and 6 months postoperatively. Early wound healing index (EHI) was used at 1 week to assess wound healing ability. Results At 6 months, radiographic parameters revealed significant reduction in DD (P<0.001) and significant DFP values in the test group compared with the control group. The supercell showed significant improvement in PPD and CAL at the end of 6 months (P<0.001). EHI scores at 1 week showed no statistically significant difference between the test and control groups. Conclusion Supercell can be considered a regenerative material in the treatment of periodontal IODs. PBMSCs (PBMSCs IOD. .

The aim of the present study was to obtain the measurements of the different humerus segments and to estimate the length of humeri from them. For this purpose 100 (51 left and 49 right) sex-aggregated, adult dry humerus from Indian population, were taken to analyze the morphometric details of the humerus segments. The distance between five different segments viz: most proximal point of the humeral head and greater tuberosity (HA), head of the humerus and surgical neck of humerus (HB), proximal and distal point of olecranon fossa (HC), the distal point of olecranon fossa and trochlea of humerus (HD), proximal point of olecranon fossa and distal point of trochlea of humerus (HE) and finally the maximum length of humerus (HL) were obtained by means of an osteometrical board and an analogical caliper. Simples linear regressions (p < 0.01) were made to correlate each segment with the total length of the humerus. Positive results were obtained in segments HB and HE of right humerus. Regressions formulae were obtained to define these estimative. In conclusion, our study demonstrated that length of the humerus can be estimated from measures of different segments of humerus and this study helps in forensic, anatomic and archeological cases in order to identify unknown bodies and to determine stature of the individual and as well as for the orthopedic surgeons for the treatment of proximal and distal humerus fractures and for their reconstruction.

El objetivo del estudio fue obtener las medidas de diferentes segmentos del húmero y calcular la longitud del húmero a partir de ellos. Fueron seleccionados 100 (51 izquierdos y 49 derechos) húmeros adultos secos, separados por sexo, de población india para analizar los detalles morfométricos de los segmentos dle hueso. La distancia entre cinco segmentos diferentes fueron establecidos: punto más proximal de la cabeza humeral y la tuberosidad mayor (HA), cabeza del húmero y cuello quirúrgico del húmero (HB), punto proximal y distal de la fosa olecraneana (HC), punto distal de la fosa olecraneana y la tróclea del húmero (HD), punto proximal de la fosa olecraneana y punto distal de la tróclea del húmero (HE) y, finalmente, la longitud máxima del húmero (HL) medidas obtenidas por medio de una tabla osteométrica y un caliper análogo. Se realizaron regresiones lineales simples para correlacionar cada segmento con la longitud total del húmero. Se obtuvieron resultados positivos en los segmentos de HB y HE de húmero derecho. Fórmulas de regresión se obtuvieron para definir estimativos. En conclusión, nuestro estudio demostró que la longitud del húmero puede estimarse a partir de las medidas de los diferentes segmentos del hueso, ayudando en casos forenses, anatómicos y arqueológicos con el fin de identificar cuerpos desconocidos o para determinar la estatura de la persona, así como a cirujanos ortopédicos para el tratamiento de las fracturas proximales y distales del húmero o para su reconstrucción.

INTRODUCTION: General surgeons dealing with laparoscopic herniorrhaphy should be aware of the aberrant obturator artery that crosses the superior pubic ramus and is susceptible to injuries during dissection of the Bogros space and mesh stapling onto Cooper's ligament. The obturator artery is usually described as a branch of the anterior division of the internal iliac artery, although variations have been reported. MATERIALS AND METHODS: The present study was conducted on 98 pelvic halves of embalmed cadavers, and the origin and course of the obturator artery were traced and noted. RESULTS: In 79% of the specimens, the obturator artery was a branch of the internal iliac artery. It branched off at different levels either from the anterior division or posterior division, individually or with other named branches. In 19% of the cases, the obturator artery branched off from the external iliac artery as a separate branch or with the inferior epigastric artery. However, in the remaining 2% of the specimens, both the internal and the external iliac arteries branched to form an anastomotic structure within the pelvic cavity. CONCLUSION: The data obtained in this study show that it is more common to find an abnormal obturator artery than was reported previously, and this observation has implications for pelvic surgeons and is of academic interest to anatomists. Surgeons dealing with direct, indirect, femoral, or obturator hernias need to be aware of these variations and their close proximity to the femoral ring.

OBJECTIVE: The tendons of the extensor carpi radialis longus and brevis muscles are quite useful in tendon transfer, such as in correction of finger clawing and restoration of thumb opposition. Knowledge of additional radial wrist extensor muscle bellies with independent tendons is useful in the above-mentioned surgical procedures. METHODS: The skin, subcutaneous tissue, and antebrachial fascia of 48 (24 on the right side and 24 on left side) male upper limb forearms were dissected. The following aspects were then analyzed: (a) the presence of additional muscle bellies of radial wrist extensors, (b) the origin and insertion of the additional muscle, and (c) measurements of the muscle bellies and their tendons. RESULTS: Five out of 48 upper limbs (10.41%) had additional radial wrist extensors; this occurred in 3 out of 24 left upper limbs (12.5%) and 2 out of 24 right upper limbs (8.3%). In one of the right upper limbs, two additional muscles were found. The length and width of each additional muscle belly and its tendon ranged between 2 - 15cm by 0.35 - 6.4cm and 2.8 - 20.8cm by 0.2 0.5cm, respectively. The additional radial wrist extensor tendons in our study basically originated either from the extensor carpi radialis longus or brevis muscles and were inserted at the base of the 2nd or 3rd metacarpal bone. CONCLUSION: The present study will inform surgeons about the different varieties of additional radial wrist extensors and the frequency of their occurrence.
