RESUMO

Seroma formation is a common sequel following modified radical mastectomy (MRM), which hinders healing, may prolong hospital stay, and cause a delay in adjuvant treatment. Closed suction drains have been used to prevent formation of seroma; however, the use of a single drain in the axilla along with draining the mastectomy flaps and axilla separately remains a topic of debate. This prospective randomized dual-arm study was conducted in the Department of Endocrine Surgery. All female patients with carcinoma breast diagnosed on core tissue biopsy, undergoing modified radical mastectomy, upfront or post neoadjuvant systemic therapy were included. Patients were randomized into two groups. In the first group, a single drain was placed in the axilla whereas in the second group, a drain each was placed below the mastectomy flaps and the axilla. Patients' particulars and the weight of the mass excised along with the operative details were documented. The volume of the drain was recorded daily. The flap drain was removed on postoperative day 5 and the axillary drain was removed when the drain volume was less than 30 mL/24 h for 2 consecutive days. The period of drain placement, volume of drainage, volume of seroma (if formed), and other complications (if any) were recorded. Patients in the single drain group had a significantly earlier drain removal time as compared to those with double drains (p = 0.01). The number of patients in whom seroma formation had occurred was more in the double drain group, but the difference was not significant. The average volume of aspirated seroma fluid was insignificantly more in the single drain group. The only other complication noticed was flap necrosis-in 5% patients of the double drain group. Total volume of drainage (p < 0.0001) and type of drain (p = 0.0208) were associated with higher rates of seroma formation, whereas BMI (p = 0.0516), weight of excised breast mass (p = 0.407), and age (p = 0.6379) were not associated with the rate of seroma formation. Outcomes in terms of drain volume or seroma formation were statistically indifferent between the two groups. Still, use of only a single axillary drain should be promoted, keeping in mind the earlier drain removal period, better patient compliance, and reduced hospital stay.

RESUMO

Breast cancer with brain metastases (BCBM) has dreadful outcomes. Various factors influencing outcomes are age, receptors status, number of distant metastases, performance status, leptomeningeal metastasis, chemotherapies, and whole brain radiation dose. This study aimed to find outcome-modifying factors in BCBM. Clinical, demographic, subtype, and pathological response of primary brain imaging characteristics of BCBM patients were correlated with brain metastasis-free interval and survival after brain metastasis was studied from January 2020 to March 2022. Triple-negative breast cancer (TNBC) patients had the earliest presentation for brain metastases (mean 45.4 years) vs luminal B (mean 57.93 years). Both brain metastasis-free interval (BMFI) and brain metastasis overall survival (BMOS) were maximum in HER2-positive subtype (mean 22.8 and 11.55 months) and least in TNBC patients (mean 9.8 and 2.12 months), respectively. Low-graded prognosis assessment (GPA) score and leptomeningeal metastasis were associated with the worst outcomes. BMFI and BMOS in patients with pathological complete response (PCR) were at 28.5 and 15.1 months, in partial response were 18.5 and 7.66 months, and with stable or progressive disease were 11 and 1.36 months, respectively. In the present study, PCR was the only modifiable parameter that changed breast cancer outcomes with brain metastasis and leptomeningeal metastasis was associated with the worst outcomes. Our study favors that PCR has prognostic importance.

RESUMO

INTRODUCTION: Acute kidney injury (AKI) occurs frequently in patients with end-stage liver disease and cirrhosis and is associated with increased short-term mortality. This study aims to study the prevalence and risk factors associated with AKI development and mortality in cirrhosis of liver patients. METHODOLOGY: In the current prospective study, hospitalized patients with liver cirrhosis from October 2021 to March 2023 were recruited. Demographic, clinical, and laboratory data were collected, which included, the etiology of cirrhosis, comorbidities, severity of liver disease, and relevant biochemical parameters. The patient was followed up for 90 days to record the clinical outcome. The statistical software SPSS was utilized to conduct the analysis. RESULTS: Of 364 liver cirrhosis patients, 25.2% (n, 92) had AKI and belonged to an average age of 51.54 ± 11.82 years. The majority of individuals in the study were males (90.4%), and alcohol (63.4%) was the most common etiology of liver cirrhosis. The present study showed that higher level of direct bilirubin (p = 0.011) and MELD score (p = 0.0001) were identified as significant risk factors for AKI development in patients with liver cirrhosis. Regarding mortality, the significant risk factors were the presence of AKI (p = 0.045) and MELD score (p = 0.025). Among AKI patients, 90-day mortality rates were higher in patients with acute tubular necrosis (p value = 0.010) and stage 3 AKI (p value = 0.001). CONCLUSION: AKI is common in cirrhosis of liver patients. Elevated levels of direct bilirubin and MELD score emerged as significant factors associated with AKI development. Furthermore, AKI and MELD scores were identified as independent risk factors for mortality at both 30 and 90 days. Survival rates were influenced by both the type and stage of AKI; AKI stage 3 and ATN patients had significantly higher mortality rate. Early AKI detection and management are crucial for reducing mortality risk in liver cirrhosis patients.

RESUMO

Organ injury stimulates the formation of new capillaries to restore blood supply raising questions about the potential contribution of neoangiogenic vessel architecture to the healing process. Using single-cell mapping, we resolved the properties of endothelial cells that organize a polarized scaffold at the repair site of lesioned peripheral nerves. Transient reactivation of an embryonic guidance program is required to orient neovessels across the wound. Manipulation of this structured angiogenic response through genetic and pharmacological targeting of Plexin-D1/VEGF pathways within an early window of repair has long-term impact on configuration of the nerve stroma. Neovessels direct nerve-resident mesenchymal cells to mold a provisionary fibrotic scar by assembling an orderly system of stable barrier compartments that channel regenerating nerve fibers and shield them from the persistently leaky vasculature. Thus, guided and balanced repair angiogenesis enables the construction of a "bridge" microenvironment conducive for axon regrowth and homeostasis of the regenerated tissue.

RESUMO

Cirrhosis patients have poor health-related quality of life (HRQoL). To enhance medical care and therapeutic approaches, it is crucial to identify factors that alter HRQoL in patients with cirrhosis. The present study aims to identify the potential factors affecting and promoting HRQoL in patients with liver cirrhosis. Four databases were extensively searched, including PubMed, Scopus, Embase, and Google Scholar. All original articles with liver cirrhosis and factor-altering HRQoL were included. The present study showed that elderly age, female gender, low family income, low body mass index (BMI), presence of anxiety and depression, presence of cirrhosis complications including ascites, hepatic encephalopathy (HE), and abnormal endoscopic findings, high disease severity score, presence of sarcopenia, disturbed sleep pattern, muscle cramps, poor sexual health, and increased levels of bilirubin, prothrombin time, and albumin-bilirubin ratio were the significant factors associated with lower HRQoL scores. Meanwhile, physical exercise, liver transplant, stem cell therapy, mindfulness, and the use of probiotics, rifaximin, and lactulose were associated with increased HRQoL scores. The present study recommends more prospective or randomized control trials with interventions including health education, yoga, psychotherapy, and other potential factors promoting HRQoL in patients with liver cirrhosis. The present study also emphasizes that the treating physician should consider taking HRQoL into account when prescribing medical therapy.

RESUMO

OBJECTIVE: We performed a systematic review to analyze the benefits of and risk factors associated with granulocyte colony stimulating factor (GCSF) in patients with liver cirrhosis. METHODS: PubMed, Scopus, and Embase were searched for randomized controlled trials and case-control studies that compared the use of GCSF with another treatment or control group. The Jadad and Newcastle-Ottawa scales were used to assess the risk of bias in the included studies. The primary outcome studied was mortality; and the secondary outcomes were the disease severity score, liver transplantation criteria, complications, CD34+ cell count, adverse events, and health-related quality of life (HRQOL). PROSPERO registration number CRD42023416014. RESULTS: The initial search yielded 2,235 studies, of which seven studies of 670 patients with liver cirrhosis were included. Multiple cycles of GCSF significantly improved the survival rate, disease severity score, CD34+ cell count, and HRQOL; and significantly reduced the incidences of liver transplantation, ascites, infection, and hepatic encephalopathy. Fatigue and backache were the most commonly reported adverse events. CONCLUSION: GCSF significantly improves the survival rate and disease severity scores, and reduces the incidence of complications in patients with liver cirrhosis. The administration of GCSF is likely to be effective in patients awaiting liver transplantation.

RESUMO

Chronic liver disease (CLD) is the major cause of mortality and morbidity, particularly in developing countries. Although there has been a significant advancement in the identification and treatment of liver diseases over time, clinical results are not satisfactory in advanced liver disease. Thus, it is crucial to develop certain technology for early detection, and curative therapies and to investigate the molecular mechanisms behind CLD's pathogenesis. The study of exosomes in CLD is a rapidly developing field. They are structurally membrane-derived nano vesicles released by various cells. In CLD, exosomes released from injured hepatic cells affect intercellular communication, creating a microenvironment conducive to the illness's development. They also carry liver cell-specific proteins and miRNAs, which can be used as diagnostic biomarkers and treatment targets for various liver diseases. End-stage liver disease can only be treated by a liver transplant, however, the low availability of compatible organs, high expenses of treatment, and surgical complications significantly lower patient survival rates. Early diagnosis and therapeutic intervention of CLD positively affect the likelihood of curative treatment and high patient survival rates. Considering the possibility that exosomes could be employed as tools for disease diagnostics and clinical intervention, The current study briefly summarizes the roles of exosomes and their cargo in diagnosing and treating liver diseases.

RESUMO

The nervous system requires metabolites and oxygen supplied by the neurovascular network, but this necessitates close apposition of neurons and endothelial cells. We find motor neurons attract vessels with long-range VEGF signaling, but endothelial cells in the axonal pathway are an obstacle for establishing connections with muscles. It is unclear how this paradoxical interference from heterotypic neurovascular contacts is averted. Through a mouse mutagenesis screen, we show that Plexin-D1 receptor is required in endothelial cells for development of neuromuscular connectivity. Motor neurons release Sema3C to elicit short-range repulsion via Plexin-D1, thus displacing endothelial cells that obstruct axon growth. When this signaling pathway is disrupted, epaxial motor neurons are blocked from reaching their muscle targets and concomitantly vascular patterning in the spinal cord is altered. Thus, an integrative system of opposing push-pull cues ensures detrimental axon-endothelial encounters are avoided while enabling vascularization within the nervous system and along peripheral nerves.

RESUMO

Mucinous cystic neoplasms are very rare tumours. They may originate from ovaries, pancreas or other intra-abdominal sites but they rarely originate from the mesentery. They can be asymptomatic or present as an abdominal mass or abdominal pain. We present the case of a 28-year-old woman who presented with epigastric pain and cystic mass per abdomen with a diagnosis of mesenteric cyst made on further imaging studies. Subsequent excision and histopathological analysis demonstrated the cyst to be a mucinous tumour arising from the mesocolon. Mesenteric cyst must be considered as one of the differentials in abdominal cystic lesions.

RESUMO

BACKGROUND: The prevalence of hepatocellular carcinoma (HCC) is increasing worldwide and it is now the third most common cause of cancer-related death. HCC is becoming a major health burden with steadily increasing incidence globally. METHODS: This is an observational study over a 3-year period in a tertiary care center in India. Three hundred and thirty-nine patients diagnosed to have HCC were included in this study. Patients' clinical, etiological, radiological and cytohistological data and therapy offered were recorded and analyzed. RESULTS: Cirrhosis of the liver was seen in 73.2% of the patients. 16.8% of patients were asymptomatic at the time of presentation. Ascites (57.2%) and jaundice (22.4%) were the most common signs of hepatic decompensation. The most common etiology of HCC was cryptogenic/non-alcoholic fatty liver disease (NAFLD) in 51% of the patients, while hepatitis B and C were seen in 17.4% and 5.8% of the patients, respectively. Advanced and end-stage disease with Barcelona Clinic Liver Cancer (BCLC) stages C and D were seen in 62.4% of patients. 56.6% had Albumin-bilirubin (ALBI) score of 2, while 62.8% had Okuda stage II disease. High alpha-fetoprotein (AFP) levels (>400 ng/mL) were seen in 48.9% of patients. Macrovascular invasion and metastases were seen in 45.9% and 22.2% of the patients, respectively. 17.6% of patients had evidence of tumor thrombus. 14.5% of biopsy specimens showed associated steatosis/steatohepatitis along with confirmation of HCC. Only 26.6% of the cirrhotic HCC patients were diagnosed during surveillance. CONCLUSIONS: HCC due to unknown cause/NAFLD appears to be overtaking hepatitis B as the commonest cause for HCC. Despite the advances in diagnostic methods and surveillance, most cases of HCC tend to be diagnosed at advanced stages.

RESUMO

Background and aim: Oesophageal candidiasis (OC) is one of the most common infections among patients with liver cirrhosis. The present study evaluates the potential predictors for OC among liver cirrhosis patients. Methodology: This retrospective study was conducted in the tertiary care centre of coastal Karnataka from January 2016 to April 2022. Patients aged 18 and above with a confirmed diagnosis of liver cirrhosis were selected. Patients were equally divided into two groups, i.e., case and control, based on the presence and absence of OC. Results: A total of 1513 patients with cirrhosis underwent upper gastrointestinal endoscopy. Of these, 50 (3.3%) were diagnosed with OC and taken into case group. An equal number of patients were selected in control group and matched for gender, age and etiology. Most participants were male (94%), with a mean age of 48.46±11.82 years. A lower serum creatinine value was noted among patients with OC. Binary logistic regression identified serum creatinine as an independent predictor for OC (OR: 7.65, 95% CI: 2.012-29.08; p-value: 0.003). The receiver operating characteristic curve for serum creatinine showed the highest significance with a cut-off of <0.86 mg/dL (AUC: 0.722). Conclusion: Serum creatinine is the independent predictor for OC among liver cirrhosis patients. The possible mechanism is that cirrhosis is a catabolic state in which muscle protein breakdown exceeds synthesis, resulting in decreased muscle mass and low creatinine levels. However, more prospective studies are required to evaluate the role of sarcopenia with OC among liver cirrhosis patients.

RESUMO

Acute kidney injury (AKI) in liver cirrhosis is associated with poor clinical outcomes including an increased long and short-term mortality. The common type of AKI observed in patients with cirrhosis are prerenal AKI (PRA), hepatorenal syndrome (HRS) and acute tubular necrosis (ATN). Despite the growing knowledge and uniform definition for the diagnosis of AKI, there are several challenges including, early diagnosis and management. Precisely differentiating the type of AKI is critical, as therapies differ significantly. In this review, we summarize AKI in liver cirrhosis, their definition, pathophysiology and deficiencies of using the existing biomarker, serum creatinine. We outline the current clinical evidence on the novel biomarker urinary neutrophil gelatinase-associated lipocalin (uNGAL) and its potential role as a biomarker in the early detection, differentiation and prognostication of AKI. This review also briefly talks about other forthcoming biomarkers which hold promise in the management of AKI in liver cirrhosis.

RESUMO

Pseudocysts are localised fluid collections, usually developing as a complication of acute or chronic pancreatitis. Pancreatic ductal or parenchymal calcifications are commonly seen in routine radiological imaging, but calcification of pseudocyst is extremely rare. Calcified pseudocysts have been reported in literature as case reports, but a calcified pseudocyst in the lesser sac, without underlying pancreatic calcification, has not been reported. We report a case of a pancreatic pseudocyst with a calcified wall, requiring surgical excision and histological examination confirming the diagnosis.

RESUMO

Although motor vehicle accidents (MVAs) in children are common, pediatric rectal perforations secondary to MVAs leading to transanal evisceration of the small bowel are very rare. Herniation of bowel through breach in the rectal wall seen eviscerating through the anus is a surgical emergency requiring laparotomy and necessary surgical procedure. We report case of a 3-year-old boy, victim of run-over MVA accident, presenting with bilateral fracture shaft femur, fracture of the left humerus, and transanal small bowel evisceration. About 30-40 cm long, gangrenous, small bowel loop was hanging outside the anal canal. Two consecutive surgeries were performed to manage this unusual and complex case with an excellent outcome. This report is presented for an extremely rare presentation of MVA injury in a child.
