Background: Bone marrow derived pluripotent stem cells hold a great promise for therapeutic repair of injured central nervous system. This report is on a six-month old paraplegic Boxer breed canine with traumatic spinal cord injury at the level of T12, which functionally recovered following intralesional transplantation of autologous Bone Marrow Mono Nuclear Cells (BMMNCs) seeded on a Thermoreversible gelation polymer (TGP) combined with intravenous Cell Transplantation. Materials and Methods: Thirty ml of Bone Marrow was aspirated and BMMNCs were isolated. From the total BMMNCs isolated, 20 x 10 6 cells were seeded in 1.5 ml of TGP and implanted at the site of injured spinal cord. A fraction of BMMNCs isolated were stored at-80deg C from which 4.16 x 10 6 BMMNCs were thawed and transfused intravenously by suspending in 2ml saline on the 19th post-operative day. The animal was followed up by assessment every two weeks for a period of two years. Results: Recovery of motor and sensory functions were noticed on the 53rd day, attempt for standing on the 79th day and ambulation on the 98th day after the initial cell transplantation. The animal had satisfactory ambulation on the 133rd day and thereafter the life style of the animal was gradually restored to normalcy. Status quo of this recovery has been maintained for the past two years. Conclusion: The outcome proves the safety of intralesional transplantation of autologous BMMNCs embedded in TGP in spinal cord injury and makes us recommend the same for more number of similar cases.

Penile cancer is a rare malignancy estimated to affect 26,000 men globally each year. The association with penile cancer, in particular non-invasive disease, and human papilloma virus (HPV) is well known. Ninety-five percent of cases of penile cancer are squamous cell carcinoma (SCC), which are staged using the TNM staging system. Terminology describing the histological appearance of non-invasive penile cancer has changed with all cases grouped under the umbrella term of penile intraepithelial neoplasia (PeIN); either undifferentiated or differentiated. This replaces previous terms such as carcinoma in situ (CIS) and eponymous names such as Bowen’s disease. This change is recognised by the World Health Organisation (WHO). The topical treatments most commonly used for PeIN are 5-fluorouracil (5-FU) and imiquimod (IQ). Other treatments such as photodynamic therapy (PDT) are used but to a lesser degree. The evidence for all of these treatments is heterogenous with no randomised data available. Overall up to 57% complete response has been reported with a low number of serious adverse events. In this article, we aim to review the available evidence for the topical treatment of non-invasive penile cancer specifically regarding its efficacy and toxicity.

A 19-year-old man presented with a right testicular swelling. Testicular ultrasound demonstrated areas suspicious for malignancy and so it was decided to proceed for a right radical inguinal orchiectomy. Initial histological examination revealed a multiloculated cystic lesion at the area of the rete testis yet normal testicular parenchyma elsewhere. Specialist histological opinion was sought from the regional teratoma multi-disciplinary team which confirmed the diagnosis of a sertoliform cystadenoma, an extremely rare benign testicular neoplasm. The recognition of the benign nature of the mass enabled complete reassurance to be offered to the patient and avoided further oncological treatment.
