In order to ensure a proper functioning of cell replication and proteins and nucleic acids synthesis processes, folate metabolism rate is also increased in these cases. For this reason, folic acid antagonists have been used since their discovery to treat different kinds of microbial infections, taking advantage of this metabolic difference when compared with human cells. However, resistances to these compounds have emerged since then and only combined therapies are currently used in clinic. In addition, some of these compounds have been found to have an immunomodulatory behavior that allows clinicians using them as anti-inflammatory or immunosuppressive drugs. Therefore, the aim of this review is to provide an updated state-of-the-art on the use of antifolates as antibacterial and immunomodulating agents in the clinical setting, as well as to present their action mechanisms and currently investigated biomedical applications. Keywords: folic acid antagonists; antifolates; antibiotics; antibacterials; immunomodulation; sulfonamides; antimalarial 1.

POST-OPERATIVE AUDIT OF G6PD-DEFICIENT MALE CHILDREN WITH OBSTRUCTIVE ADENOTONSILLAR ENLARGEMENT AT UNIVERSITY COLLEGE HOSPITAL, IBADAN, NIGERIA. John EN1, Totyen EL1, Jacob N2, Nwaorgu OGB1 1 .Department of ENT/Head and Neck Surgery, University College Hospital, Ibadan, Nigeria 2. Department of paediatrics, University College Hospital, Ibadan, Nigeria All correspondences and request for reprint to Dr John EN, Department of ENT/Head and Neck Surgery, University College Hospital, Ibadan, Nigeria Email: [email protected] Telephone: +2348036240109 Abstract Background: G6PD deficiency ranks among the commonest hereditary enzyme deficiency worldwide and notable as a predisposing condition to haemolyticcrises. The fear of possible untoward effects is often expressed by parents of G6PD deficient male children scheduled for surgery after obtaining an informed and understood consent. The parental perception of obstructive adenotonsillar enlargement in this condition was also appraised. Methods: A retrospective chart review of all G6PD deficient male children between ages 1 to 7years who had adenotonsillectomy over a 3year period at University college Hospital, Ibadan, Nigeria. Results: The patients comprised of 22 G6PD deficient male children diagnosed shortly after birth upon development of neonatal jaundice. Fifteen(68.2%) and 6(27.3%) of the patients subsequently developed episodes of drug- induced haemolysis and non-haemolytic drug reactions prior to undergoing adenotonsillectomy by the otolaryngologists. None of the patients was observed to develop haemolytic crises up to 2weeks post-adenotonsillectomy. From the parental perception and responses in the follow-up period,all 22(100%) patient had resolution of noisy breathing, 20(91%) had improvement of snoring and apnoeic spells. Only 15 (68%) were reported to stop mouth-breathing.

Photodegradation Assessment of Ciprofloxacin, Moxifloxacin
Hubicka et al. Chemistry Central Journal 2013, 7:133 http://journal.chemistrycentral.com/content/7/1/133 RESEARCH ARTICLE Open Access Photodegradation assessment of ciprofloxacin, moxifloxacin, norfloxacin and ofloxacin in the presence of excipients from tablets by UPLC-MS/MS and DSC Urszula Hubicka1*, PawełŻmudzki2, Przemysław Talik1, Barbara Żuromska-Witek1 and Jan Krzek1 Abstract Background: Ciprofloxacin (CIP), moxifloxacin (MOX), norfloxacin (NOR) and ofloxacin (OFL), are the antibacterial synthetic drugs, belonging to the fluoroquinolones group. Fluoroquinolones are compounds susceptible to photodegradation process, which may lead to reduction of their antibacterial activity and to induce phototoxicity as a side effect. This paper describes a simple, sensitive UPLC-MS/MS method for the determination of CIP, MOX, NOR and OFL in the presence of photodegradation products. Results: Chromatographic separations were carried out using the Acquity UPLC BEH C18 column; (2.1 × 100 mm, 1.7 μm particle size). The column was maintained at 40°C, and the following gradient was used: 0 min, 95% of eluent A and 5% of eluent B; 10 min, 0% of eluent A and 100% of eluent B, at a flow rate of 0.3 mL min-1. Eluent A: 0.1% (v/v) formic acid in water; eluent B: 0.1% (v/v) formic acid in acetonitrile. The method was validated and all the validation parameters were in the ranges acceptable by the guidelines for analytical method validation. The photodegradation of examined fluoroquinolones in solid phase in the presence of excipients followed kinetic of the first order reaction and depended upon the type of analyzed drugs and coexisting substances.

NORPRAMIN® (Desipramine Hydrochloride Tablets USP)
NORPRAMIN® (desipramine hydrochloride tablets USP) Suicidality and Antidepressant Drugs Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Anyone considering the use of NORPRAMIN or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. NORPRAMIN is not approved for use in pediatric patients. (See WARNINGS: Clinical Worsening and Suicide Risk, PRECAUTIONS: Information for Patients, and PRECAUTIONS: Pediatric Use.) DESCRIPTION NORPRAMIN® (desipramine hydrochloride USP) is an antidepressant drug of the tricyclic type, and is chemically: 5H-Dibenz[bƒ]azepine-5-propanamine,10,11-dihydro-N-methyl-, monohydrochloride. 1 Reference ID: 3536021 Inactive Ingredients The following inactive ingredients are contained in all dosage strengths: acacia, calcium carbonate, corn starch, D&C Red No. 30 and D&C Yellow No. 10 (except 10 mg and 150 mg), FD&C Blue No. 1 (except 25 mg, 75 mg, and 100 mg), hydrogenated soy oil, iron oxide, light mineral oil, magnesium stearate, mannitol, polyethylene glycol 8000, pregelatinized corn starch, sodium benzoate (except 150 mg), sucrose, talc, titanium dioxide, and other ingredients.
