RESUMEN
Introduction Polycystic ovary syndrome (PCOS) is a prevalent hormonal disorder characterized by irregular menstrual cycles, ovarian cysts, and elevated androgen levels. The potential association between trace elements, specifically copper (Cu) and zinc (Zn), and PCOS has been explored, but a definitive relationship remains unclear. This study aims to investigate the levels of these trace elements in women with PCOS and their potential implications. Methods The study, conducted at Gauhati Medical College & Hospital, involved 60 individuals with PCOS and a matched control group. Ethical approval was obtained, and participants provided written informed consent. The study spanned from July 2021 to June 2022, utilizing a hospital-based case-control study design. Diagnostic criteria adhered to the Rotterdam criteria, and serum copper and zinc levels were quantified using a double-beam UV spectrophotometer. Results In the PCOS group, the mean age was 23.01 ± 3.60 years, while the control group had a mean age of 23.34 ± 3.59 years, with no significant age difference. Mean copper levels were 147.32 ± 16.53 µg/dl in PCOS and 106.88 ± 15.60 µg/dl in controls, indicating a significant increase in PCOS (p < 0.0001). Mean zinc levels were 93.99 ± 6.76 µg/dl in PCOS and 85.42 ± 12.69 µg/dl in controls, also significantly higher in PCOS (p < 0.0001). Conclusion The study highlights significant differences in serum copper and zinc levels between women with PCOS and healthy controls, suggesting potential implications for the syndrome's pathophysiology. Further research is warranted to elucidate the precise roles of these trace elements in PCOS and explore therapeutic interventions.
RESUMEN
Introduction: Acute kidney injury (AKI) is a presentation of an underlying heterogeneous group of conditions that leads to impairment of filtration and excretion of nitrogenous waste products from the body. A prompt early diagnosis to detect AKI is a mandate due to the associated risk of high mortality and morbidity. We tested the sensitivity and specificity of plasma neutrophil gelatinase-associated lipocalin (NGAL), a potential biomarker of AKI, versus serum creatinine, the gold standard laboratory test. Materials and Methods: A cross-sectional diagnostic type study was conducted from February 2015 to January 2017 after obtaining the institutional ethics clearance certificate. Individuals admitted to the intensive care unit (ICU) of a tertiary care hospital of northeast India who were diagnosed with septicemia, heart failure, and ketoacidosis and individuals on nephrotoxic drugs such as aminoglycosides were included in the study. Serum creatinine and plasma NGAL of all individuals were estimated using suitable methods within 24 h of admissions. Results: Considering all inclusion and exclusion criteria, 138 individuals were included in the study. The area under the curve (AUC) for plasma NGAL on day 1 of admission was 0.800 (95% confidence interval [CI]: 0.712-0.882). In the study, we estimated a plasma NGAL cut-off value of 391 ng/mL (with an odds ratio of 9.89) within the day of admission. Conclusion: Plasma NGAL is a candidate biomarker of AKI with acceptable sensitivity and specificity (AUC of 0.80) that can predict AKI in our setup before serum creatinine is raised, thereby asking for a prompt intervention to reduce the mortality and morbidity associated with AKI.
RESUMEN
Diagnosis of prostate cancer (PC) has posed a challenge worldwide due to the sophisticated and costly diagnostics tools, which include DRE, TRUS, GSU, PET/CT scan, MRI, and biopsy. These diagnostic techniques are very helpful in the detection of PCs; however, all the techniques have their serious limitations. Biosensors are easier to fabricate and do not require any cutting-edge technology as required for other imaging techniques. In this regard, point-of-care (POC) biosensors are important due to their portability, convenience, low cost, and fast procedure. This review explains the various existing diagnostic tools for the detection of PCs and the limitation of these methods. It also focuses on the recent studies on biosensors technologies as an alternative to the conventional diagnostic techniques for the detection of PCs.

Introduction The stature of an individual is an important parameter for establishing identification. The height of an individual can be indirectly estimated from different parts of the skeleton and such measurements are of great use in forensic science, anatomy, and anthropometry. This study was an attempt to formulate a linear regression equation for estimation of stature by measuring the ulnar length in the living adult Khasi population. Methods The study population consists of 164 subjects (Male: 118; Female: 46) between 25 and 45 years of age. The left and right ulnar lengths were measured from the tip of the olecranon process to the tip of the styloid process with the elbow flexed and palm spread over the opposite shoulder by a spreading caliper. The measurements of the stature of the volunteers were done in the standard anatomical standing position with a bared foot with the head in the Frankfort plane. The documented data were calculated by the standard statistical software. Results The height and ulnar length in males (160.85 ± 6.34 cm and 24.41 ± 1.10 cm, respectively) were found to be significantly (p < 0.001) higher than females (149.56 ± 2.95 cm and 22.58 ± 0.47 cm, respectively). Significant positive correlation coefficient (r) between height (cm) and ulnar length (cm) were observed in both males (r = 0.955, P < 0.001) and females (r = 0.915, P < 0.001), respectively. Conclusion The length of the ulna provides an accurate and reliable means in estimating the height of an individual; being almost a percutaneous bone, its length can be measured easily. The regression formulae that were derived in this study will be useful for clinicians, human anatomists, archeologists, anthropologists, and forensic experts.
RESUMEN
Introduction Coexistence of diabetes mellitus and thyroid diseases is common. One of the main microvascular complications of diabetes is diabetic nephropathy (DN) and it is found to be the leading cause of chronic kidney disease. The aim of the present study was to assess the association between hypothyroidism and serum potassium levels in diabetic nephropathy patients. Materials and methods A cross-sectional study was conducted from March 2020 to January 2021. We enrolled 100 patients with DN along with 50 healthy controls belonging to the same localities. Serum potassium, creatinine, thyroid-stimulating hormone (TSH) and total triiodothyronine (T3) levels of all the cases were measured to establish the correlation of serum potassium along with each parameter separately. Results Serum potassium, creatinine, TSH levels were increased in all the cases of diabetic nephropathy showing positive correlations of serum potassium with serum TSH and serum creatinine levels with correlation coefficient values 0.71 and 0.7 respectively and serum T3 levels were decreased in all the cases significantly showing negative correlation with serum potassium levels with correlation coefficient value -0.34. Conclusion Estimation of serum TSH and T3 levels along with serum potassium levels is important and helpful in patients with diabetic renal disease. Changes in thyroid parameters like decreased TSH or increased T3 are significantly associated with deterioration in the severity of renal function in diabetic patients.
RESUMEN
Various dermatological manifestations have been observed in patients with Coronavirus disease (COVID-19) infection ranging from maculopapular rashes, urticaria, chickenpox-type lesions, chilblain-like, distal-limb ischemia, and livedo racemosa. While most of these cutaneous findings are self-resolving, they may aid in the timely diagnosis of this infection. We are reporting three patients presenting with dermatological features resembling (i) varicella zoster, (ii) herpes labialis, and (iii) Steven Johnson Syndrome (SJS) who were subsequently diagnosed with Covid-19 infection. The skin lesions disappeared after successful treatment of Covid-19.
RESUMEN
Introduction Hydatid disease is an immense health problem in developing countries. The diagnosis of hydatid cyst is often difficult because of its protean manifestations. Our objective was to evaluate the various clinical and laboratory presentations of hydatid disease and various modalities of treatment from a tertiary care center. Materials and methods We reviewed the clinical and laboratory features of patients presenting with hydatid cyst through retrospective analysis from January 2018 to December 2019 from a tertiary care hospital in northeast India. Results Of the 26 adult patients with hydatid cysts who were part of the study, 14 (53.8%) were males and 12 (46.2%) were females. The mean age was 34.6 years. The most common site of involvement was the liver (69%) followed by lung (19.2%) and brain (7.7%). Palpable mass in the right upper quadrant of the abdomen was the most common symptom (88.3%) for liver hydatid cyst followed by pain abdomen (66.6%). Systemic symptoms like fever and weakness were present in most of the patients. The majority of patients (80%) were from rural areas. Conclusion Hydatid cysts present with varied symptomatology. History of exposure to infected animals may not be present. A high degree of clinical suspicion combined with meticulous history and clinical examination supported by laboratory investigations are required for its diagnosis.
RESUMEN
INTRODUCTION: One of the more specific assessments of the metabolic status of bone in normal and in disease conditions is the measurement of bone specific alkaline phosphatase or ostase. The measurement of serum ostase has several advantages over the measurements of other bone parameter. Because of its relatively long half-life, in-vivo (1 to 3days), it is relatively unaffected by diurnal variation. AIM: To find the correlation of serum ostase level in hyper and hypothyroid cases and also to study the validity of routine estimation of serum ostase in hyper and hypothyroid cases so as to monitor the base level bone health on presentation. MATERIALS AND METHODS: Serum ostase level was studied in 74 patients with disorder of thyroid function. Serum ostase level, Thyroid Stimulating Hormone (TSH), FT3, FT4 levels were estimated by chemiluminescent technique. The instrument used was Beckman- coulter Access 2. A total of 39 patients were hypothyroid, 31 were hyperthyroid and 4 patients had subclinical hyperthyroidism. RESULTS: The serum ostase level was found to be elevated above 40 µg/L in 26 of the cases and above 16 µg/L but below 40µg/L in 5 cases of hyperthyroidism along with decrease in Bone Mineral Density (BMD). Serum ostase level was found to be directly proportional to the serum FT3 level (Normal range of serum ostase is 8-16 µg/L). CONCLUSION: From this study, an inference can be drawn that a routine estimation of serum ostase level in hyperthyroid cases will help in proper monitoring of decrease bone turnover as indicated by increase serum ostase level. Besides, the estimation of serum ostase level in hyperthyroid cases it is found to be valid in this study, which can turn to be an important guiding parameter to the treating physician to formulate necessary protocols and guidelines for prophylaxis, treatment and to monitor the response to therapy in cases of reduced bone turnover related to hyperthyroid state.
RESUMEN
PURPOSE: Secondary hyperparathyroidism (SHPT) is one of the less recognized reasons of anemia in chronic kidney disease (CKD). In this study, we evaluated the role of SHPT as a cause of anemia and correlation of intact parathyroid hormone (iPTH) and hemoglobin (Hb) level in hemodialysis (HD) patients. METHODS: This cross-sectional study was carried out in 63 individuals admitted in HD unit of the institute. Serum samples were collected and urea, creatinine, Hb, ferritin and iPTH levels were measured. Statistical analysis was carried out using the SPSS software (IBM, NY, USA). RESULTS: Mean ± standard deviation for serum urea, creatinine, Hb, ferritin and intact PTH were 177 ± 15.52, 15.16 ± 2.28 mg/dl, 7.03 ± 2.26 g/dl, 654.7 ± 563.4 ng/ml, 539.18 ± 493.59 pg/ml respectively. A reverse correlation was found between intact PTH and Hb level. CONCLUSIONS: A variety of postulated pathophysiological mechanisms linking SHPT and anemia in CKD are discussed. An efficient control of parathyroid hormone hypersecretion may be required to achieve a better management of anemia in HD patients.
