1.Increased Biceps Translation: A Clinical Sign of Complete Distal Biceps Tendon Rupture.
Clinics in Shoulder and Elbow 2016;19(1):48-50
Various tests to help in the clinical diagnosis of distal biceps tendon ruptures have been described. In our experience these tests are painful in the acute setting. We suggest a simple alternative test wherein the biceps muscle belly is held by the examiner and translated medially and laterally. This is done with the forearm flexed to 90 degrees. It is first performed with the biceps relaxed and subsequently performed with the forearm flexed against resistance. In the relaxed forearm the biceps easily translates over 50% of its width. When placed under tension (by flexing against resistance) this translation is significantly reduced. In cases of complete distal biceps tendon rupture, the biceps still translates, even under resisted flexion of the forearm. This simple test is less painful than other described tests, is easy to perform, and aids in clinical diagnosis of distal biceps tendon ruptures.

OBJECTIVES:
This study examined the effects of plasma-rich growth factors (PRGF) on accelerating bone regeneration/repair in fresh extraction sockets, and determined the quality and quantity of bone by assessing the bone density using cone-beam computed tomography (CBCT).
MATERIALS AND METHODS:
Twenty patients, who had undergone bilateral extractions, were included in this study. In one extraction socket, PRGF was used and covered with an autologous fibrin plug. Nothing was used in the opposite side extraction socket. Thirteen weeks post extraction, the level of bone regeneration was evaluated on both sides with CBCT.
RESULTS:
At the end of the study, the mean bone density according to the Hounsfield units (HU) in the control group and PRGF group was 500.05 HU (type III bone type) and 647.95 HU (type II bone type), respectively.
CONCLUSION
This study recommends the use of PRGF in post extraction sites to accelerate the rate of bone regeneration and improve the quality of regenerated bone. The technique to process PRGF was simple compared to previously mentioned techniques used for platelet-rich plasma (PRP) preparation. PRP preparation requires a two-cycle centrifugation procedure, leading to a longer processing time.

4.Induced Pluripotent Stem (iPS) Cells in Dentistry: A Review.
International Journal of Stem Cells 2016;9(2):176-185
iPS cells are derived from somatic cells via transduction and expression of selective transcription factors. Both viral-integrating (like retroviral) and non-integrating (like, mRNA or protein-based) techniques are available for the production of iPS cells. In the field of dentistry, iPS cells have been derived from stem cells of apical papilla, dental pulp stem cells, and stem cells from exfoliated deciduous teeth, gingival and periodontal ligament fibroblasts, and buccal mucosa fibroblasts. iPS cells have the potential to differentiate into all derivatives of the 3 primary germ layers i.e. ectoderm, endoderm, and mesoderm. They are autogeneically accessible, and can produce patient-specific or disease-specific cell lines without the issue of ethical controversy. They have been successfully tested to produce mesenchymal stem cells-like cells, neural crest-like cells, ameloblasts-like cells, odontoblasts-like cells, and osteoprogenitor cells. These cells can aid in regeneration of periodontal ligament, alveolar bone, cementum, dentin-pulp complex, as well as possible Biotooth formation. However certain key issues like, epigenetic memory of iPS cells, viral-transduction, tumorgenesis and teratoma formation need to be overcome, before they can be successfully used in clinical practice. The article discusses the sources, pros and cons, and current applications of iPS cells in dentistry with an emphasis on encountered challenges and their solutions.

5.Cestode fauna of hill-stream fishes in Garhwal Himalayas, India.
The Korean Journal of Parasitology 1983;21(2):205-208
Ptychobothrium nayarensis n. sp. has been described from two hill-stream fishes, Barilius bola(Ham.) and Schizothorax richardsonii(Gray) at 325-750 mASL. The new species has been compared with close species. Taxometric evaluation of the new species has been done on available data.

8.Epilepsy and abnormal MRI brain findings in a patient with Duchenne’s muscular dystrophy – A rare association

Epilepsy in Duchene’s muscular dystrophy, though more prevalent than in general population, is seen
in only 6-10% cases of DMD. Earlier studies have reported nonspecific MRI findings in DMD patients
with epilepsy. We report a patient of DMD, diagnosed on muscle biopsy who had definite MRI brain
imaging abnormalities. Our case highlights the rare association of MRI brain signal changes in this
patient with DMD.

9.Medial Ball and Socket Total Knee Arthroplasty in Indian Population: 5-Year Clinical Results
Clinics in Orthopedic Surgery 2022;14(1):90-95
Background:
Medial pivot total knee arthroplasty aims to restore native knee kinematics through highly conforming medial tibiofemoral articulation with survival comparable to contemporary knee designs. The aim of this study was to report preliminary clinical results of medial pivot total knee arthroplasty in an Indian population.
Methods:
A retrospective analysis of 45 patients (average age, 62 years; 40 women and 5 men) with end-stage arthritis (KellgrenLawrence grade 4) operated with a medial pivot prosthesis was done. All patients were assessed using Knee Society Score (satisfaction, expectation, and functional scores) and Oxford Knee Score, and range of motion was recorded at the end of 5-year postoperative follow-up. In addition, all patients underwent standardized radiological assessment.
Results:
At the final follow-up, patients reported significant improvement in mean Knee Society Score (satisfaction, expectation, and functional scores) and Oxford Knee Score (p < 0.05). The mean range of motion achieved at the end of 5 years ranged from 0° (extension) to 118.4° (further flexion). There was no evidence of loosening or osteolysis at a minimum follow-up of 5 years.
Conclusions
These results demonstrated satisfactory clinical and radiological outcomes at 5 years after total knee arthroplasty with a medial pivot design, which may be related to better replication of natural knee kinematics with the medial pivot knee and inherent advantages of this design.
10.A case report of an accessory flexor digitorum profundus indicis contributing the first lumbrical
Arjun MALHOTRA ; Randy KULESZA
Anatomy & Cell Biology 2022;55(3):390-393
Variations of the musculature within the upper extremity have been widely documented, with clinical implications ranging from motor dysfunction to compressive neuropathies. Herein, we described an aberrant muscle that originated from the anterior proximal forearm, formed a tendon that coursed through the carpal tunnel, and converged with the flexor digitorum profundus muscle to contribute to the first lumbrical. Additionally, the second lumbrical consisted of two heads, originating from the index and middle finger tendons of flexor digitorum profundus. Documentation and recognition of such anatomic variants is important, as this anatomic pattern may contribute to anterior interosseous or median nerve compression, incoordination, complications during surgery, and other clinical manifestations.
