A Study on the Risk Factors associated with Stroke in young adults and its Management Practices
Get PDFThe various risk factors causing premature stroke and cardiovascular diseases in young adults and their management are increasing problems in both developed and developing countries. Cardiovascular diseases include heart conditions that involve diseased vessels, structural problems, and blood clots. This is a prospective observational study which was conducted for 6 months in the general medicine department of Gandhi Hospital, Hyderabad. The study was initiated after the approval by Institutional Ethical Committee. During the study period a total number of 80 cases were collected. Out of these cases (55 cases, 69%) were of ischemic stroke and (25 cases, 31%) of hemorrhagic stroke. It was observed that males were more prone to strokes and females are more prone to cardiovascular diseases. The most common risk factor associated with stroke was hypertension. The age group of 41–50 years was mostly affected by stroke and cardiovascular diseases. Therefore, from our study we observe that timely treatment and patient counselling on disease, disease management and medications are important parameters for better patient care and improving quality of life.

Correlation of hyperprolactinemia, Subclinical hypothyroidism with Polycystic Ovary Syndrome and infertility
Get PDFBackground: Polycystic ovarian syndrome (PCOS) is a hyperandrogenic condition characterized by polycystic ovarian morphology and chronic oligo-anovulation. When it is combines with hypothyroidism and hyperprolactinemia, this condition can have severe consequences, may even lead to infertility.
Case Presentation: This case study illustrates the complexity of PCOS and the significance of a multidisciplinary approach to its diagnosis and therapy. The patient is a 24-year-old non diabetic nonsmoker female with PCOS who has been attempting to conceive for seven years. The patient presented to the hospital with irregular menstrual cycles and a desire to become pregnant. The patient had previously been unsuccessfully treated with Clomid and letrozole. The patient\u27s BMI was determined to be 23. 3 and a pelvic scan indicated PCO ovaries. Laboratory results revealed hyperprolactinemia (53 ng/ml) and subclinical hypothyroidism (TSH 12.6 uIU/ml, T4 0.54 ng/dL- TPO antibodies:187 IU/mL, Anti thyroglobulin antibodies 235 IU/mL), but a pituitary gland MRI was normal. Thyroid US features going with Hashimoto thyroiditis. The patient\u27s PCOS symptoms were initially managed with metformin and Duphaston, and then Cabergoline was introduced to address hyperprolactinemia. The patient became pregnant shortly following hyperprolactinemia medication. Prenatal screenings revealed elevated fasting glucose levels and gestational diabetes. The patient\u27s blood sugar was initially controlled by Metformin, but she later required multiple insulin doses to maintain control. The patient was scheduled for induction of labor at 38 weeks, but a lower segment emergency cesarean surgery was performed due to fetal distress.
Conclusion: Regular monitoring and management of both PCOS and related conditions such as hypothyroidism and hyperprolactinemia are crucial to ensure the best outcome for the patient. Additionally, we suggest Metformin, Duphaston, Cabergoline to treat PCOS patient having subclinical hypothyroidism and hyperprolactinemia.

A Review on the Some Biological Activities of the Hydantoin Derivatives: .
Get PDFHydantoin derivatives are commonly used anticonvulsants. In general, they are effective for partial-onset seizures and tonic-clonic seizures, but not for absence seizures. Phenytoin is the most important drug in this group, and other drugs, ethotoin, and mephenytoin, are also commonly used to treat epilepsy. Prodrugs such as derivatives have been created. Phenytoin is effective in some cases of trigeminal neuralgia and related neuralgia. Phenytoin is also used to treat arrhythmias. Hydantoins or glycolylureas are heterocyclic organic compounds with the formula CH2C(O)NHC(O)NH. It is a colorless solid formed by the reaction of glycolic acid and urea. It is an oxidized derivative of imidazolidine. In a more general sense, hydantoins can refer to groups and classes of compounds that share the same ring structure as their parent. For example, phenytoin (see below) has two phenyl groups substituted at the 5th carbon of the hydantoin molecule. Actual chemotherapy for epilepsy dates back to the 1850s when "inorganic bromides" were introduced. However, it is worth noting that around the 1920s, the therapeutic and beneficial use of \u27phenobarbital\u27 usheredin an era of meaningful treatment of epilepsy. Hydantoin ring chemistry is the synthesis of rings by various methods and their applications in the medical field. Previous descriptions of hydantoin-containing compounds have broad pharmacological and biological activities, including anticancer, anti-inflammatory, anti-immune, antimetabolite, antioxidant, antibacterial, CNS-related, anticonvulsant, antitussive, and cytoprotective activities.

A Stability Indicating Method was Developed and Validation for the Estimation of Carbamazepine in Bulk and Tablet Dosage form by UV-Spectroscopic Techniques
Get PDFCarbamazepine is an anticonvulsant. It works by decreasing nerve impulses that cause seizures and nerve pain, such as trigeminal neuralgia and diabetic neuropathy. It is well known that contemporary pharmaceutical analysis establishes robust, sensitive, economic, stability-indicating analytical procedures. The current study aimed to develop and assess UV-spectrophotometric (zero order, first order, second order, area under the curve) methods for estimating carbamazepine in its pharmaceutical dosage form. Method A is a simple zero-order spectrophotometric method for determining carbamazepine at 285 nm, and the correlation coefficient in the linearity study was found to be 0.9976, LOD, and LOQ are 0.45 and 1.48 µg/ml. Method B is a first-order spectrophotometric method for determining carbamazepine at 269 nm, and the correlation coefficient in the linearity study was found to be 0.9944, LOD, and LOQ are 0.29 and 0.96 µg/ml. Method C is a second-order spectrophotometric method for determining carbamazepine at 254 nm, and the correlation coefficient in the linearity study was found to be 1.00, LOD, and LOQ are 0.62 and 2.04 µg/ml. Method D is an area under the curve spectrophotometric method for determining carbamazepine at 266 to 300 nm, and the correlation coefficient in the linearity study was found to be 0.9975, LOD, and LOQ are 0.14 and 0.46 µg/ml. All developed methods demonstrated good repeatability and recovery with %RSD < 2. Studies on stress degradation show that oxidation and acid degradation mostly impact carbamazepine solutions.

Pyrogallol is a key component for xanthine oxidase inhibition by the leaves of Ammannia baecifera: Pyrogallol as XOD inhibitor of A. baecifera leaves
No full textAmmannia baecifera Linn is an important plant in traditional medication system of Bangladesh. In order to give the scientific clarification for using this plant in the treatment of gout, this study was designed to identify the xanthine oxidase (XO) inhibitors present in the extract of Ammannia baecifera leaves along with evaluating its antioxidant effect. First aqueous extract was prepared from leaves and then water insoluble part (WIP) was separated from water soluble part (WSP) as precipitate with ethanol. In DPPH and ABTS assays, WSP with rich amount of phenolic compound exhibited high radical scavenging activity than WIP. WSP also showed potent XO inhibition with IC50: 18.03 ± 1.65 μg/mL value. Using different chromatographic techniques, the key XO inhibitor was isolated from WSP and identified as pyrogallol based on its different spectroscopic data. In XO inhibition assay, pyrogallol (IC50: 11.67 ± 0.45 μg/mL) showed potent inhibitory effect as compared to a known XO inhibitor (allopurinol; IC50 = 27.35 ± 1.15 μg/mL) and it also displayed strong DPPH and ABTS radical scavenging effect. In addition, an inhibition kinetics study indicated that WSP and pyrogallol are mixed competitive inhibitors of XO. The overall results suggest that the presence of pyrogallol as XO inhibitor and free radical scavenger in Ammannia baecifera leaf justifies the traditional uses of this plant.
