RESUMEN

Background: The incidence of hip fractures is increasing every year worldwide. Even though hemiarthroplasty is one of the most common procedures performed for a fractured neck of the femur, there is very little research comparing the outcomes of monoblock and modular systems, the two most commonly used prostheses in neck of the femur fractures. It was hypothesized that in narrow femoral canals, the single-size monoblock stem would be more difficult to insert and lead to complications like limb lengthening and intra-operative calcar fractures. The objective of our study was to compare the outcomes of a modular prosthesis with that of a monoblock prosthesis in a fractured neck of the femur. Materials and Methods: This study analyzed the surgical outcomes of 192 cases of hemiarthroplasties performed over a 4-year period using a modular system and compared it to 192 cases performed using a single-sized monoblock system. Results: The monoblock systems were more likely to cause post-operative limb lengthening compared to their modular counterparts (P = 0.01). The incidence of intra-operative fractures was also more in the monoblock system, although it was not statistically significant. Up to 45% of patients required a femoral stem size smaller than the single-sized monoblock system as the optimum size for their femoral canals, which was available only in the modular system. Conclusions: Modular prosthesis was found to have lower chances of post-operative limb lengthening and lower chances of intraoperative calcar fractures compared to monoblock prosthesis. Careful pre-operative radiologic planning is essential in cases where monoblock systems are used, and the modular system might serve as a viable solution in such scenarios.

RESUMEN

PURPOSE: Accurate understanding of the genomic and transcriptomic data provided by next-generation sequencing (NGS) is essential for the effective utilization of precision oncology. Molecular tumor boards (MTBs) aim to translate the complex data in NGS reports into effective clinical interventions. Often, MTB treatment recommendations differ from those in the NGS reports. In this study, we analyze the discordance between these recommendations and the rationales behind the discordances, in a non-high-income setting, with international input to evaluate the necessity of MTB in clinical practice. METHODS: We collated data from MTB that were virtually hosted in Chennai, India. We included patients with malignancies who had NGS reports on solid tissue or liquid biopsies, and excluded those with incomplete data. MTB forms and NGS reports of each clinical case were analyzed and evaluated for recommendation concordance. Concordance was defined as an agreement between the first recommendation in the MTB forms and the therapeutic recommendations suggested in the NGS report. Discordance was the absence of the said agreement. The rationales for discordance were identified and documented. RESULTS: Seventy MTB reports were analyzed with 49 cases meeting the inclusion criteria. The recommendation discordance was 49% (24 of 49). Discordant recommendations were mainly due to low level of evidence for the drug (75% of cases). CONCLUSION: The discordance between MTB and NGS vendor recommendations highlights the clinical utility of MTB. The educational experiences provided by this initiative are an example of how virtual academic collaborations can enhance patient care and provider education across geographic borders.

RESUMEN

Pyoderma gangrenosum (PG) is a neutrophilic dermatosis of unknown aetiology. We report a 27-year-old male patient with diabetes, who presented with a nonhealing ulcer on the left leg, pruritic hyperpigmented papules distributed over the trunk and limbs, and chronic diarrhoea. He had eosinophilia, low haemoglobin and serum IgE levels, and raised erythrocyte sedimentation rate. Histopathology of the leg ulcer was consistent with the diagnosis of PG, while the histology of the hyperpigmented papule revealed tissue eosinophilia. Subsequent evaluation was conclusive of the diagnosis of PG, idiopathic hypereosinophilic syndrome (IHES) and selective IgE deficiency. Dexamethasone pulse therapy achieved resolution of the ulcer and reduction in the eosinophilia. Further evaluation for the persistent diarrhoea led to a diagnosis of lymphocytic colitis (LC), which responded to budesonide. To our knowledge, the association of PG with IHES, selective IgE deficiency or LC has not been previously reported.

RESUMEN

The management of recurrent renal cell carcinoma is challenging as it requires close collaboration between surgeons, radiation oncologists and medical oncologists. To date, treatment options for metastatic disease have been of modest benefit. The disease has therefore been a good model for novel drug development programs. These endeavors are now bearing fruit with exciting preliminary data now emerging in relation to a number of novel agents.

RESUMEN

Fibroblast growth factor receptor 4 (FGFR4) is expressed in 50-70% of pancreatic carcinomas (PC) and a similar proportion of derived cell lines. Here we determine the sites of FGFR4 transcriptional initiation which show a pattern characteristic of genes with GC-rich, TATA-less promoters. We have examined the chromatin structure around the FGFR4 gene in a panel of expressing and non-expressing PC lines using the DNase I hypersensitive site assay. One region of hypersensitivity, located largely within intron 1, was found to be greatly extended in expressing cells. Subsequent functional analyses using reporter assays demonstrated that this region was able to act as a cell-specific enhancer, only showing significant activity in PC lines expressing endogenous FGFR4. Transcription factors able to bind to the enhancer were investigated using footprinting and mobility shift assays and two binding sites for Sp1 proteins and two sites able to bind hepatic nuclear factor 1 (HNF1) proteins were identified. Further reporter assays using constructs mutated in each binding site demonstrated that HNF1 binding was essential for enhancer activity in expressing cells, an observation that correlated with the increased abundance of HNF1alpha in these same cells as measured by Western blotting. Finally we show that exogenous expression of HNF1 factors in an FGFR4 non-expressing line led to an induction of enhancer activity in reporter assays and also activated expression of the endogenous gene. We conclude that HNF1alpha is a major determinant of FGFR4 expression in PC.
