Tubercular dactylitis in a 65 year old female: a rare case report

Tubercular dactylitis is defined as tubercular infection of the metacarpals, metatarsals and phalanges. It is a rare form of extra pulmonary tuberculosis. Bones of the hand are more commonly affected than the bones of the feet. Tubercular dactylitis is common in children and children below 6 year of age accounts for 85% of cases. The diagnosis is usually by a combination of clinical suspicion coupled with radiological investigation and confirmation by biopsy. We hereby present a case report of tubercular dactylitis in a 65 year old female which was treated by antitubercular therapy

SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL EVALUATION OF SOME 1, 2, 4-TRIAZOLE DERIVATIVES

Objectives: To synthesize, characterize and evaluate antimicrobial properties of some 1, 2, 4-triazole derivatives. Methods: A novel series of 1, 2, 4-Triazole derivatives (D-1-D-8) had been synthesized. Ethyl esters of benzoic and 4-substituted benzoic acids were synthesized using ethanol and conc. sulphuric acid. In the second step, hydrazides of these esters were prepared. This hydrazide was converted into potassium salt of dithiocarbazinate using carbon disulfide and potassium hydroxide which on cyclization formed compounds (D-1-D-2). Compound D-3 was formed by reacting D-1 with 4-methylbenzenesulfonyl chloride in dry pyridine. Compounds (D-4-D-8) were synthesized by mixing aqueous solution of 10% NaOH in different primary amines and then heating it with potassium salt of dithiocarbazinate. The structures of newly synthesized compounds were established on the basis of 1H NMR and Mass spectroscopic techniques. The newly synthesized compounds were screened for their in vitro antibacterial and antifungal activity. In vitro antibacterial and antifungal activity was evaluated by Disc Diffusion method. Ofloxacin and Clotrimazole were used as standard drug respectively. Results: The results revealed that compounds D-3 and D-4 exhibited good antibacterial activity and D-1 and D-2 had moderate antibacterial activity as compared with standard drug Ofloxacin, while compounds (D-5-D-8) exhibited moderate antifungal activity as compared to standard drug Clotrimazole. Conclusion: A novel series of 1, 2, 4-Triazole derivatives were synthesized and were obtained in good yields. Newly synthesized compounds were isolated and purified by thin layer chromatography and column chromatography respectively

Hydrophobicity Directed Chiral Self-Assembly and Aggregation-Induced Emission:Diacetylene-Cored Pseudopeptide Chiral Dopants

Here we delineate simple and tunable hydrophobically driven chiral functional assemblies of diacetylene cored pseudopeptides. These amino acid appended, rigid core dialkynes constitute promising chiral supramolecular building blocks for materials properties engineering. The chiral appended amino acid elements allow for simple tuning of solubility and interaction properties as well as governing chirality, while the central dialkyne core can impart hydrophobically driven assembly and Aggregation Induced Emission (AIE) properties. The self-assembly of these rod-like dialkynes can be regulated by tuning the solvent environment, with for example self-assembly into vesicles in acetonitrile and into helical organization with AIE in a H 2 O/DMSO mixture. Of additional high interest, these supramolecular materials, themselves devoid of liquid crystal (LC) properties, can induce chirality into non-chiral LC matrices with high helical twisting power. </p

Filgrastim as a Rescue Therapy for Persistent Neutropenia in a Case of Dengue Hemorrhagic Fever with Acute Respiratory Distress Syndrome and Myocarditis

Pathogenesis of dengue involves suppression of immune system leading to development of characteristic presentation of haematological picture of thrombocytopenia and leucopenia. Sometimes, this suppression in immune response is responsible for deterioration in clinical status of the patient in spite of all specific and supportive therapy. Certain drugs like steroids are used for rescue therapy in conditions like sepsis. We present a novel use of filgrastim as a rescue therapy in a patient with dengue hemorrhagic fever (DHF) with acute respiratory distress syndrome (ARDS), myocarditis, and febrile neutropenia and not responding to standard management
