A Pilot Study of Functional Outcomes in Adult Patients Treated With Valgus Intertrochanteric Osteotomy as a Primary Modality for Intracapsular Femoral Neck Fracture.

Background Intracapsular femoral neck fractures account for a majority of hip fractures. This study aimed to investigate the efficacy of valgus osteotomy as a primary treatment for intracapsular femoral neck fractures in adult patients aged 15-60 years, assessing its impact on functional outcomes and fracture union. Methodology A retrospective clinical analysis was conducted at the Department of Orthopedics and Traumatology, Osmania Government General Hospital, Hyderabad, India, focusing on patients treated with primary intertrochanteric valgus osteotomy for intracapsular femoral neck fractures. The study reviewed medical charts and radiographs of six patients aged between 15 and 60 years, diagnosed with recent isolated intracapsular femoral neck fractures, presenting between May 2019 and October 2021. The intervention involved Pauwels' intertrochanteric valgus osteotomy with various fixation methods. Main outcome measures included radiographic union, functional ability assessed by the Harris Hip Score, and evaluation for complications. Results All six patients achieved radiographic union at fracture and osteotomy sites, totaling a 100% success rate. The average follow-up duration was 14.8 months (12-20 months), with an average time of 5.1 months (2.5-6 months) from surgery to radiographic union. One patient experienced union with retroversion, while another developed avascular necrosis (AVN) by the study's conclusion. No instances of hardware failure or non-union were observed. The average Harris Hip Score obtained during the most recent clinical follow-up was 84, ranging from 69 to 94. All six patients regained independent walking ability without any support by the end of the follow-up period. Conclusion The combination of primary Pauwels' intertrochanteric valgus osteotomy with fixed-angle plating proves to be a highly effective method for addressing recent intracapsular femoral neck fractures, resulting in a 100% success rate in achieving union among the patient cohort.

The relationship between BCG immunotherapy and oxidative stress parameters in patients with nonmuscle invasive bladder cancer.

INTRODUCTION: Environmental chemicals have been associated with the regulation of oxidative stress markers, which have the potential for the development of bladder cancer. However, limited studies on the function of oxidative stress parameters and nonmuscle invasive bladder cancer (NMIBC) in therapy response are available. Here we studied the oxidative stress parameters in response to BCG immunotherapy in NMIBC patients. MATERIAL AND METHODS: A total of 120 patients with NMIBC and treatment with BCG were enrolled and categorized into 2 groups on BCG response, 50 patients were BCG-responsive (BCG-R) and 70 were BCG-nonresponsive (BCG-N). BCG-R have no evidence of tumor recurrence or advancement after 1 year of BCG immunotherapy, but BCG-N has a recurrence of tumor after 3 to 6 months cycles of BCG instillation, as determined by cystoscopy. In all groups, we measured the levels of oxidative stress markers- malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase (SOD), and catalase (CAT). RESULTS: The levels of oxidative stress markers viz. MDA, NO, and SOD in the BCG-N group were significantly higher (P < 0.001) than in the BCG-R group. Furthermore, the data demonstrated a significant correlation between oxidative stress marker and NMIBC T1 high grade and tumor size >2.5 cm. However, no statistically significant difference was found between studied groups with CAT. CONCLUSION: The findings suggest that the carcinogenesis of NMIBC is associated with oxidative damage of biomolecules and indicates the involvement of oxidative stress markers in the development and recurrence of NMIBC.; Therefore, it is critical to ensure the management for T1 high grade and tumor size of >2.5 cm for antioxidant protection.

CYP1A1 gene polymorphism and heavy metal analyses in benign prostatic hyperplasia and prostate cancer: An explorative case-control study.

INTRODUCTION: The prostatic disorder is associated with benign prostatic hyperplasia (BPH) and prostate cancer (CaP). Evidently, prevalent transcription factors and signaling pathways define their relationship. The etiology of the prostatic disorder is multifactorial including heavy metal toxicity like lead (Pb), Cadmium (Cd), and genetic factors. This study elucidates the association between heavy metal toxicity Pb, Cd, and CYP1A1 gene polymorphism with BPH and CaP. METHODS: a case-control study with (BPH, n = 104), (CaP, n = 58) and (controls, n =107) patients. Heavy metal Pb and Cd estimation by atomic absorption spectrophotometer. The polymorphism of the CYP1A1 T>C (rs4646903) gene was analyzed byPCR-RFLP. RESULT: Higher levels of Pb and Cd were found in BPH and CaP followed by the control group (P-value: < 0.05). Pb and Cd show a significant correlation among prostate volume in CaP. Additionally, PSA, IPSS score, and pre void volume were positively co-related with Pb in BPH patients. The posthoc test defines the level of Pb and Cd as significantly elevated in the mutant genotype, highest among homozygous mutant genotype of CYP1A1gene among BPH. In CaP, Pb is significantly higher among the homozygous mutant type of CYP1A1 gene. The risk is also influenced by smoking, tobacco, and alcohol. CONCLUSION: The heavy metal toxicity Pb and Cd were reported to raise the risk of BPH and CaP. However, a person with heavy metal toxicity especially in BPH has a high-risk genetic susceptibility to the CYP1A1 gene in the north Indian population.

Association of severity and mortality of Covid-19 cases among acute kidney injury and sexual dimorphism.

INTRODUCTION: The outbreak of coronavirus disease 2019 (Covid-19) severely impacted global health and economic status. The native receptor-ligand interaction of Angiotensin-converting enzyme 2 (ACE2) and S protein induces host cell pathogenesis via immunosuppression. MATERIAL AND METHODS: The emerging evidence reports the sex disparity in Covid-19 induced mortality rate which affects abundantly men population. Although the biological interaction of Covid-19 with receptor upregulates the viral genome protein interactions and initiates the predictive multiorgan failure followed by acute kidney injury (AKI) in Covid-19 infected male population. CONCLUSION: Besides, the knowledge and lessons learned from the study depict that cellular and molecular links may explain the risk and severity of Covid-19 and AKI in the male population and lead to management of Covid-19 induced AKI. Therefore, this review explored the pathways associated with the pathogenesis of two diseased conditions with sex disparity.

Xanthogranulomatous cystitis with malakoplakia leading to recurrent spontaneous bladder perforation in a young girl.

Recurrent bladder perforation due to xanthogranulomatous cystitis with malakoplakia is rare entity and can lead to spontaneous bladder perforation. A 15 years girl presented with sudden pain abdomen with reduced urine output. Her exploratory laparotomy revealed, perforation of 2 cm at the dome of bladder with unhealthy margins. Excisional bladder biopsy and repair of bladder perforation by 3-0 polyglactin suture was done. The histopathology showed xanthogranulomatous cystitis with malakoplakia. Her records revealed the same histopathology in bladder perforation at age of 9 with lost follow-up till age of 15. Exploratory laparotomy and bladder repair should be done to save the patient.

Associated pathogenesis of bladder cancer and SARS-CoV-2 infection: a treatment strategy.

Coronavirus disease 19 (Covid-19) is a pandemic that affects every human on Earth. Mortality rates are greater in people with both cancer and Covid-19. In comparison, patients with non-Muscle-Invasive Bladder Cancer (NMIBC) had reduced susceptibility to moderate Covid-19 mortality. The treatment and clinical management of NMIBC are consistent with BCG-mediated intravesical adjuvant therapy as a protective function against tumors. BCG vaccination exhibits a non-specific protective role against respiratory infections. This non-specific effect of BCG is partially mediated by innate immune memory due to epigenetic changes in innate and adaptive immune system cells induced by the microbe. This editorial suggests that regularly test repurposed drugs include anti-cancer drugs till the proper antiviral drugs or vaccines will be developed.

Acute Kidney Injury in COVID-19: a Brief Review.

The contemporary evolution of the coronavirus disease 2019 (COVID-19) outbreak from the Wuhan, China, with a high rate of transmission will act the global medical emergency with immense morbidity and mortality rate across the world. The cell entry of COVID-19 via angiotensin-converting enzyme 2 receptor (ACE-2 receptor) will damage the respiratory system by the cytopathic effect induced by replication of the virus genome in the host and respond respiratory failure with an elevation of cytokine factor-like interleukin (IL) IL-6, IL-8, tumor necrosis factor-alpha (TNF-alpha), etc. However, the lung-kidney cross talk will evidence the activation of molecular mechanisms from pro-inflammatory cytokines and concerned with kidney damage, though the elevated rate of ACE-2 receptor in the kidney will enhance the possibility of mortality with consideration of acute kidney injury. This review provides relevant information which suggests the rate of mortality in COVID-19 patient associated with acute kidney injury (AKI) which lacks critical monitoring of kidney function with a clinical consideration of intervention to avoid kidney damage in the initial stage of the disease.

Role of JAK/STAT in the Neuroinflammation and its Association with Neurological Disorders.

Background: Innate immunity is mediated by a variety of cell types, including microglia, macrophages, and neutrophils, and serves as the immune system's first line of defense. There are numerous pathways involved in innate immunity, including the interferon (IFN) pathway, TRK pathway, mitogen-activated protein kinase (MAPK) pathway, Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway, interleukin (IL) pathways, chemokine pathways (CCR5), GSK signaling, and Fas signaling. Summary: JAK/STAT is one of these important signaling pathways and this review focused on JAK/STAT signaling pathway only. The overactivation of microglia and astrocytes influences JAK/STAT's role in neuroinflammatory disease by initiating innate immunity, orchestrating adaptive immune mechanisms, and ultimately constraining inflammatory and immunological responses. The JAK/STAT signaling pathway is one of the critical factors that promotes neuroinflammation in neurodegenerative diseases. Key message: Given the importance of the JAK/STAT pathway in neurodegenerative disease, this review discussed the feasibility of targeting the JAK/STAT pathway as a neuroprotective therapy for neurodegenerative diseases in near future.
