Topical Minocycline Induced Bluish Black Hyperpigmentation in Acne Vulgaris Patient: The First Case Report of Topical Application: The First Case Report of Topical Application
No full textMinocycline induced hyperpigmentation is an aesthetically unsetting adverse drug event. Oral minocycline inducing hyperpigmentation is common course, keeping in line with this topical minocycline 4% was formulated. A moderately built woman diagnosed with acne was prescribed with topical minocycline 4% Gel and after 15 days of application she noticed dark patches on applied areas which progressed into macules. On examination, it was found that the topical minocycline has induced Type I (Bluish Black) Hyperpigmentation. To the best of clinician’s knowledge, the drug was withdrawn and observed over a period of month. Post-withdrawal for 30-days the skin started to regain its original tone. Regardless of the fact that the topical formulation has been designed to reduce the drug contact with the systemic circulation and to decrease the side-effects, will the formulation succeed in providing the effective and safe therapy in acne patients?

Biopharmaceutical distribution and pharmacodynamic evaluation of intra nasal in-situ gel of Lamotrigine for brain targeted drug delivery
Get PDFBackground: The present research investigates the nasal delivery of Lamotrigine by incorporating it into a natural in-situ gelling system. Additionally, the retention of the drug in the nasal cavity was enhanced by employing the natural mucoadhesive polymer locust bean gum (LBG). A preliminary investigation was conducted to determine the optimal concentration of gellan gum. The dosage of the drug was calculated using the Robinson Erikson equation. The central composite design was utilized to optimize the influence of individual variables such as gellan gum and locust bean gum on various responses, including gelation time, gel viscosity, mucoadhesive strength, and the time taken for the drug to release half of its initial concentration (t50). The goal of the current study was to evaluate the in-vivo effectiveness of intra nasal in-situ gel of Lamotrigine.
Methodology: The pharmacokinetic and tissue distribution studies were carried out to evaluate the brain targeting efficiency of lamotrigine. Blood samples and tissues of various vital organs like brain, liver, kidneys and heart were obtained at different time intervals, plasma and tissue concentration of Lamotrigine was estimated by reverse phase HPLC.
Results: According to the pharmacokinetic analysis, Cmax and AUC0-α is found to be significantly more (P<0.05) for nasal route compared to oral route. In comparison to the oral route, Cmax and AUC0-α was 7 and 6.5 folds more for IN route. The absolute bioavailability was found to be 159.07%. with regard to the oral group, minimal drug was present in any of the other tissue samples. In the pharmacodynamic data also the formulation through nasal route showed a significant difference compared to oral route (pure drug suspension) delivery in PTZ induced study.

Cystic Lesion of the Adrenal Gland: A Case Report
Get PDFBackground: Cystic lesions in the adrenal glands are infrequent and unusual occurrences, with only a handful of cases documented thus far. These lesions come in various types, exhibiting diverse origins and sharing similar clinical presentations, ranging from benign to potentially malignant cystic growths. Typically, they do not cause symptoms, but in some rare instances, they may lead to abdominal discomfort or a sense of fullness. Due to their rarity, there is ongoing debate surrounding the most effective approach for managing adrenal cysts.
Case Presentation: This case report presents a case of a 36-year-old female who presented with a history of abdominal pain and was incidentally found to have a right adrenal cyst during a CT scan. She exhibited no additional symptoms, such as hypertension, headache, or palpitations. Laparoscopic right adrenalectomy was performed, successfully removing the cystic mass without complications. Preoperative laboratory tests, including endocrine function tests, were unremarkable. Imaging studies, including ultrasound and contrast-enhanced CT, characterized the cyst as a large, well-circumscribed, low-attenuated structure with peripheral calcifications, distinct from the right suprarenal gland. Gross examination revealed a collapsed cyst measuring 7 x 3 cm with a smooth inner wall, and the right adrenal gland measured 4 x 2.5 cm. The histological analysis identified the lesion as an adrenal pseudocyst with a fibrous wall containing focal dystrophic microcalcifications and embedded adrenocortical cells. No endothelial lining, eosinophils, or parasites were present. The patient\u27s postoperative course was uneventful, and she was discharged in stable condition the following day.
Conclusion: This case demonstrates the effective management of a large adrenal pseudocyst through laparoscopic adrenalectomy, resulting in a successful outcome without complications. Comprehensive imaging and histopathological evaluation were crucial in confirming the diagnosis and guiding treatment.

Antioxidant and cytotoxic activities of protein hydrolysates from shrimp shell wastes, germinated soybean and pigeon pea flour blends: A mixture response surface methodology approach
Get PDFCancer has high prevalence rate and mortality with conventional chemotherapy and other management protocols being both expensive and inaccessible especially in low/medium income countries (LMIC). Sourcing alternative cheaper and easily accessible treatment from blends of antioxidants sources can reduce the burden of cancer on patients. This work therefore seeks to produce a blend from the protein hydrolysates of shrimp shell waste, germinated soybean and germinated pigeon pea which not only has high antioxidant activity but also can inhibit cervical cancer cell proliferation. In vitro antioxidant and cytotoxic activities of the mixtures of germinated pigeon pea, germinated soybean, and shrimp shell waste hydrolysates were evaluated using the mixture response surface methodology (MRSM). Fourteen blends were obtained using the simplex centroid design. Total phenolic content (TPC), 2, 2-Diphenyl-1-Picrylhydrazyl (DPPH) and % cytotoxicity of the samples were analysed. Numerical optimization was conducted with the goal of simultaneously maximizing the DPPH scavenging activity and TPC while minimizing % cytotoxicity. The optimized blend consisted of 91.06 % pigeon pea, 8.94 % shrimp shell waste and 0 % soybean. The predicted responses obtained were 74.28 % DPPH scavenging activity, 39.6 GAE mg/dL TPC and 21 % cytotoxicity. The IC50 values for the optimized blend and a standard chemotherapeutic drug were 0.260 mmol/mL and 0.013 mmol / mL respectively. This in vitro study revealed that the pigeon pea - shrimp shell waste blend, as generated by MRSM, was comparable to a standard anticarcinogenic drug with respect to potency.
