OBJECTIVE: To examine management of cellulitis in a tertiary teaching hospital, identify inefficiencies and suggest revised management guidelines. DESIGN: Retrospective case survey, based on patient hospital records. SETTING: Heidelberg Repatriation Hospital, Melbourne, Victoria (a tertiary teaching hospital), in 1991 and 1992. SUBJECTS: All patients admitted with lower-limb cellulitis as the primary diagnosis. RESULTS: 118 patients were included. Underlying disease predisposing to cellulitis was found in 79%, but was adequately investigated in only 20% of these. Blood cultures were performed in 55%, all with negative results. Other microbiological investigations also had poor yields. Combination therapy with intravenous (i.v.) flucloxacillin and penicillin was given to 76%, with duration varying widely (mean, six days). Where documented (73%), most patients (94%) responded to antibiotics within five days. However, in 40% of patients i.v. therapy was continued for longer and in 10% for 10 days or more, with no significant difference in outcome. Length of hospital stay averaged 13 days, with prolonged stay often associated with surgical intervention or intercurrent problems. However, 15% of patients remained in hospital longer than 10 days for no clear indication. Outpatient review was common (75%), but persistence or relapse of cellulitis was found in only four patients on review. CONCLUSIONS: Management of inpatients with cellulitis is inefficient, with excessive use of microbiological investigations, inadequate investigation and treatment of underlying disease, prolonged use of intravenous antibiotics, unnecessarily long hospital stays, questionable use of combination antibiotic therapy and excessive outpatient review (rather than review by a local medical practitioner).
Technetium-aspirin and technetium-aspirin-like molecule complexes were prepared. The structure of N-acetyl-anthranilic acid (NAA) has been decided through CNDO calculations. The ionization potential and electron affinity of the NAA molecule as well as the charge densities were calculated. Comparative studies of the electronic absorption spectra of acetylthio-salicylic acid (ATS) and aspirin (Asp) reveal the structure resemblance in which the acetyl carbonyl group is perpendicular to the plane of the corresponding organic acid. The studies of the electronic absorption spectra of NAA and anthranilic acid reveal the planarity of the NAA molecule. The electronic absorption spectra of Tc(V)-Asp and Tc(V)-ATS complexes have two characteristic absorption bands at 450 and 600 nm, but the Tc(V)-NAA spectrum has one characteristic band at 450 nm. As a comparative study, Mo-ATS complex was prepared and its electronic absorption spectrum is comparable with the Tc-ATS complex spectrum.
Claisen reaction of 4-acetyl[2.2]paracyclophane (1) with ethyl acetate and diethyl oxalate affords 4-acetoacetyl[2.2]paracyclophane (2) and ethyl (4-oxaloacetyl[2.2]paracyclophane) (6), respectively. Reaction of 2 and 6 with hydrazines and CuCl2 gave the pyrazole derivatives 4 and 8 in addition to the metal complexes 5 and 9. Mannich reaction of 2 with benzylamine and paraformaldehyde yielded the piperidinone derivative 3. The biological activity of all new compounds was tested.
Eleven strains of Enterococcus (Streptococcus) faecalis isolated from Laban Rayeb, a type of fermented milk, had been studied when grew in milk. Enterococcus (Streptococcus) faecalis strains 19 and 22 were the most active strains in the production of lactic acid, acetaldehyde and diacetyl. Both strains exhibited a high proteolytic activity besides a good clean flavour. Based on the obtained results, Enterococcus (Streptococcus) faecalis 19 and 22 could be used to bring about the lactic fermentation during the manufacture of some cultured dairy products.
5-Azo(4'-substituted benzenesulphamoyl)-8-hydroxyquinolines(III) have been prepared by coupling of the appropriate p-substituted benzenesulphamoyldiazonium acetates with 8-hydroxyquinoline. The corresponding copper chelates(IV) and iron chelates(V) were also prepared in a 1:2 metal to ligand ratio. Structures of III, IV and V were confirmed by some representative UV, IR, and NMR spectrometry in addition to microanalysis. Antidotal activity of four ligands (IIIa, IIId, IIIf, and IIIi) has been evaluated in mice against the toxicity of lead acetate and copper sulphate. Study revealed that compound IIIf elicited significant antidotal activity against lead and copper poisoning, while IIIi was potent only against lead poisoning. Antibacterial activity of compounds III, IV, and V was also determined in comparison to sulphanilamide against Staph. aureus, Bacill. cereus, and Esch. coli. The test compounds showed variable bacteriostatic activities, and some of them (IIIc, IIId, IIIf, Ve, IIIg, and Vi) are more effective than the reference drug, especially against Bacill. cereus.
