Acute prostatitis after prostate biopsy under ciprofloxacin prophylaxis with or without ornidazole and pre-biopsy enema: analysis of 3. 479 prostate biopsy cases

ABSTRACT Objectives: To investigate the characteristics of cases of NIH category I acute prostatitis developed after transrectal prostate biopsy and clarifiy the risk factors and preventive factors. Materials and Methods: We retrospectively reviewed the medical records of 3.479 cases of transrectal ultrasound-guided needle biopsies performed with different prophylactic antibiotherapy regimens at two different institutions between January 2011 and February 2016. The patients of Group I have received ciprofl oxacin (n=1.523, 500mg twice daily) and the patients of Group II have received ciprofl oxacin plus ornidazole (n=1.956, 500mg twice daily) and cleansing enema combination as prophylactic antibiotherapy. The incidence, clinical features and other related microbiological and clinical data, were evaluated. Results: Mean age was 62.38±7.30 (47-75), and the mean prostate volume was 43.17±15.20 (21-100) mL. Of the 3.479 patients, 39 (1.1%) developed acute prostatitis after the prostate biopsy procedure. Of the 39 cases of acute prostatitis, 28/3.042 occurred after the first biopsy and 11/437 occurred after repeat biopsy (p=0.038). In Group I, 22 of 1.523 (1.4%) patients developed acute prostatitis. In Group II, 17 of 1.959 (0.8%) patients developed acute prostatitis. There was no statistical difference between the two groups according to acute prostatitis rates (X2=2.56, P=0.11). Further, hypertension or DM were not related to the development of acute prostatitis (P=0.76, X2=0.096 and P=0.83, X2=0.046, respectively). Conclusions: Repeat biopsy seems to increase the risk of acute prostatitis, while the use of antibiotics effective for anaerobic pathogens seems not to be essential yet.

Comparative study on the efficacy of non-steroidal, steroid and non-use of anti-inflammatory in the treatment of acute epidemic conjunctivitis

Abstract Purpose To evaluate the effects of prednisolone against sodium diclofenac both with ciprofloxacin compared to artificial tears on the symptoms and signs of acute viral conjunctivitis. Methods Study included 37 patients diagnosed with acute conjunctivitis and distributed by three groups: A (1% prednisolone acetate + ciprofloxacin (0.3%); B (Sodium diclofenac (0.1%) + ciprofloxacin (0.3%) and C (artificial tears + ciprofloxacin (0.3%). Patients received medication 6/6 hours daily. Signs and symptoms (e.g. lacrimation, burning, photophobia, etc.) were scored at baseline and on the first, third, fifth and seventh days and in the end of treatment using a standardized questionnaire and slit lamp anterior segment examination. Results All three groups demonstrated an improvement in the signs and symptoms of conjunctivitis in their follow-up visits. There was no significant difference in symptom and sign scores between Group A and B and B and C in the study visits ( p >0.05). However, the comparison between groups A and C showed a clinical trend (p=0.05) on third evaluation suggesting better clinical action using the corticosteroids. Conclusion The prednisolone acetate was not superior to the use of sodium diclofenac or artificial tears in relieving the signs and symptoms of viral conjunctivitis.

Prescripción de ciprofloxacino por vía parenteral en pacientes ingresados en los servicios de Medicina Interna y Caumatología de un hospital general / Parenteral prescription of ciprofloxacin in patients admitted to the Internal Medicine and Caumatology services of a general hospital

Se realizó un estudio observacional descriptivo y transversal de 76 pacientes ingresados en los servicios de Medicina Interna y Caumatología del Hospital General Docente Dr Juan Bruno Zayas Alfonso de Santiago de Cuba durante el 2012, para evaluar los conocimientos, el desempeño y la satisfacción de 22 profesionales que prescribieron ciprofloxacino por vía parental. Los conocimientos y la satisfacción fueron evaluados a través de un examen de conocimientos y una encuesta de satisfacción, respectivamente; el desempeño, a partir de la información obtenida de las historias clínicas, relacionadas con tres criterios: individualización del tratamiento, esquema terapéutico y combinaciones medicamentosas. Para cada criterio se establecieron indicadores y estándares. Los prescriptores presentaron conocimientos adecuados sobre el medicamento en cuestión; sin embargo, el desempeño y la satisfacción de estos resultaron inadecuados. Se considera necesario realizar una intervención en aras de revertir las deficiencias identificadas y contribuir a elevar la calidad de la prescripción de medicamentos en ambos servicios de salud

A descriptive, cross-sectional and observational study of 76 patients admitted to the Internal Medicine and Caumatology services of Dr Juan Bruno Zayas Alfonso Teaching General Hospital was carried out in Santiago de Cuba during 2012, to evaluate the knowledge, performance and satisfaction of 22 professionals who prescribed parental ciprofloxacin. The knowledge and satisfaction were evaluated through a knowledge examination and a survey of satisfaction, respectively; the performance was evaluated, starting from the information obtained from the medical records, related to 3 criteria: individualization of the treatment, therapeutic schedule and medication combinations. For each opinion, indicators and standards were established. The prescribers presented appropriate knowledge on the specific medication; however, the performance and satisfaction of them were inadequate. It is necessary to carry out an intervention to revert the identified deficiencies and contribute to elevate the quality of the medications prescription in both health services

Aneurisma de aorta abdominal infectado por Salmonella species / Infected abdominal aneurysm due to Salmonella species

Os aneurismas de aorta abdominal infecciosos (AAAIs) são raros e apresentam uma alta mortalidade devido à septicemia e ao risco de ruptura. A opção terapêutica consagrada consiste na correção aberta com ressecção do aneurisma, debridamento e reconstrução com veia autóloga. Mais recentemente, alguns grupos vêm relatando séries de casos nas quais se realizou tratamento endovascular. Em ambas as opções, a antibioticoterapia adjuvante é imperativa. Relatamos um caso ilustrativo em que o tratamento de escolha foi a cirurgia aberta com reconstrução utilizando-se veia autóloga.

Infected abdominal aortic aneurysms are rare and have high mortality due to sepsis and the possibility of rupture. The treatment of choice is open repair with aneurysm resection, debridement and reconstruction with an autologous vein graft. More recently, case series have been described in which the endovascular approach was the first option. With both approaches adjuvant antibiotic therapy is imperative. We report an illustrative case in which the treatment was open surgery reconstruction using an autologous vein graft.

The efficacy of duration of prophylactic antibiotics in transrectal ultrasound guided prostate biopsy

ABSTRACT Introduction: We aimed to evaluate the efficacy of the duration of prophylactic antibiotic administration in patients undergoing transrectal ultrasound (TRUS) guided biopsy. Material and Methods: A total of 367 patients undergoing a prostate biopsy between September 2007 and June 2009 was reviewed retrospectively and divided into 2 groups according to prophilaxy: oral ciprofloxacin (750 mg every 12 hours) for 3 or more days in Group-1 and single day in Group-2. Demographic characteristics of patients, symptoms, PSA values, IPSS scores, prostate sizes, pathologic results and complications were compared between the groups. Results: The mean age of all patients was 63.92 years and the mean PSA was 13.61ng/ dL. The pre-biopsy mean IPSS score was 12.47 and mean prostate volume 52.53 mL. For 78.2% of patients the current biopsy was their first biopsy. Cancer detection rate was 24.2%. Fever was observed in 3 (1.2%) patients in Group-1 and 5 (4.0%) patients in Group-2. Local infections occurred in 2 (0.8%) and 1 (0.8%) patients respectively in Groups 1 and 2. Acute prostatitis was observed in only 1 (0.8%) patient in Group-2. Accepted after revision: None of the patients developed septicemia or other serious infection. There was no statistically significant difference in terms of fever, local infections (epididimitis, orchitis, etc.) and acute prostatitis. Conclusions: In a selected patient population single dose prophylaxis with ciprofloxacin can be safely administered compared to other regimens of 3 or more days. Increasing the duration of antibiotic prophylaxis does not decrease infectious complications.

Pentacyclic triterpenes combined with ciprofloxacin help to eradicate the biofilm formed in vitro by Escherichia coli.

Background & objectives: Ciprofloxacin is commonly used in clinical practice for the treatment of recurrent urinary tract infections caused by Escherichia coli. However, very often these recurrent infections are due to a failure in a complete eradication of the microorganisms colonizing the urinary tract, especially in catheterized patients. To enhance the bactericidal activity of ciprofloxacin against biofilm-forming uropathogenic E. coli (UPECs), we examined its effect in combination with two pentacyclic triterpenes – asiatic and ursolic acids. Methods: The anti-biofilm activity of ciprofloxacin and pentacyclic triterpenes - asiatic acid (AA) and ursolic acid (UA), as well as their synergistic effect were tested on two types of surfaces - polystyrene microtiter plates and silicone catheters. It was investigated using the time-killing and biofilm assays. Results: anti-biofilm activity of ciprofloxacin was not observed on microtiter plates or on the catheters. Ciprofloxacin combined with ursolic acid inhibited the biofilm formation on microtitre plates. This mixture, however, did not express such a strong activity against the synthesis of biofilm on the surface of catheters. Ciprofloxacin combined with asiatic acid had very weak inhibiting effect on the synthesis of biofilm mass on microtitre plates as well as on the catheters. Despite this, both mixtures – ciprofloxacin and asiatic acid, as well as ciprofloxacin and ursolic acid, exhibited strong and significant impact on the eradication of mature biofilm (P < 0.05). Interpretation & conclusions: Although ciprofloxacin is recommended in the treatment of urinary tract infections caused by UPECs, but its efficacy is arguable. Subinhibitory concentrations of ciprofloxacin did not inhibit the formation of biofilm. Pentacyclic triterpenes used in combination with ciprofloxacin enhanced its anti-biofilm effectiveness. However, this anti-biofilm activity was found to depend on the type of surface on which biofilm was formed.

The efficacy of immediate versus delayed antibiotic administration on bacterial growth and biofilm production of selected strains of uropathogenic Escherichia coli and Pseudomonas aeruginosa

Purpose The treatment of urinary tract infections (UTI) with antibiotics is commonly used, but recurrence and antibiotic resistance have been growing and concerning clinicians. We studied whether the rapid onset of a protective biofilm may be responsible for the lack of effectiveness of antibiotics against selected bacteria. Materials and Methods Two established uropathogenic Escherichia coli strains, UTI89 and CFT073, and two Pseudomonas aeruginosa strains, PA01 and Boston-41501, were studied to establish a reliable biofilm formation process. Bacterial growth (BG) was determined by optical density at 600 nm (OD 600) using a spectrophotometer, while biofilm formation (BF) using crystal violet staining was measured at OD 550. Next, these bacterial strains were treated with clinically relevant antibiotics, ciprofloxacin HCl (200 ng/mL and 2 μg/mL), nitrofurantoin (20 μg/mL and 40 μg/mL) and ampicillin (50 μg/mL) at time points of 0 (T0) or after 6 hours of culture (T6). All measurements, including controls (bacteria -1% DMSO), were done in triplicates and repeated three times for consistency. Results The tested antibiotics effectively inhibited both BG and BF when administered at T0 for UPEC strains, but not when the antibiotic administration started 6 hours later. For Pseudomonas strains, only Ciprofloxacin was able to significantly inhibit bacterial growth at T0 but only at the higher concentration of 2 μg/mL for T6. Conclusion When established UPEC and Pseudomonas bacteria were allowed to culture for 6 hours before initialization of treatment, the therapeutic effect of selected antibiotics was greatly suppressed when compared to immediate treatment, probably as a result of the protective nature of the biofilm. .

In vitro Bioluminescence Used as a Method for Real-Time Inhibition Zone Testing for Antibiotic- Releasing Composites.

Aims: This study describes the potential of real-time bioluminescence imaging in evaluating the antibiotic efficiency of two cylinder-shaped bioabsorbable antibiotic-releasing composites by in vitro inhibition zone tests. The bacterial infections of bone tissue can cause extensive hard and soft tissue damage and decrease the efficiency of oral antibiotic therapy due to the poor blood circulation in the infected area. To overcome this problem, new, locally antibiotic-releasing biodegradable composites have been developed. Study Design & Methodology: The two composites evaluated in this study were composed of poly(L-lactide-co-ε-caprolactone) matrix, β-tricalcium phosphate ceramic and either ciprofloxacin or rifampicin antibiotic. The composites were tested with genetically modified model pathogens of osteomyelitis (Pseudomonas aeruginosa and Staphylococcus epidermidis) in vitro in inhibition zone tests using a method of real-time bioluminescence. Results: The first signs of the effect of the released ciprofloxacin or rifampicin became visible after four hours of incubation and were seen as changed bioluminescence around the composite pellet on a culture dish. Both of the composite types showed excellent effects against the sensor bacteria within the diffusion area. Bioluminescence measurements suggested that no survivor bacteria capable of evolving resistant strains were left inside the inhibition zones. The S. epidermidis bacterial strain was an inhibition sensor and P. aeruginosa was a stress sensor. Conclusion: These results highlight the potential of the composite materials against the pathogens of osteomyelitis. The approach allows continuous visual inspection of the efficacy of the antibiotics against the bacteria

Susceptibility of Escherichia coli from Community-Acquired Urinary Tract Infection to Fosfomycin, Nitrofurantoin, and Temocillin in Korea

With increase of multi-drug resistant Escherichia coli in community-acquired urinary tract infections (CA-UTI), other treatment option with a therapeutic efficacy and a low antibiotic selective pressure is necessary. In this study, we evaluated in vitro susceptibility of E. coli isolates from CA-UTI to fosfomycin (FM), nitrofurantoin (NI), temocillin (TMO) as well as trimethoprim-sulfamethoxazole (SMX), ciprofloxacin (CIP) and cefepime (FEP). The minimal inhibitory concentrations were determined by E-test or agar dilution method according to the Clinical and Laboratory Standards Institute guidelines, using 346 E. coli collected in 12 Korean hospitals from March 2010 to February 2011. FM, NI and TMO showed an excellent susceptibility profile; FM 100% (346/346), TMO 96.8% (335/346), and NI 99.4% (344/346). Conversely, resistance rates of CIP and SMX were 22% (76/346) and 29.2% (101/349), respectively. FEP still retained an activity of 98.5%. In Korea, NI and TMO in addition to FM are a good therapeutic option for uncomplicated CA-UTI, especially for lower UTI.

Use of glass ionomer cement containing antibiotics to seal off infected dentin: a randomized clinical trial

Dental materials with antibacterial properties can prevent the harmful effects caused by oral cariogenic bacteria. This double-blind controlled clinical trial evaluated the performance of a glass ionomer cement (GIC) added with antibiotics for sealing infected dentin in atraumatic restorations of primary molars. The study enrolled 45 children (45 teeth) between 5 and 8 years of age, of both genders, divided into two groups: GC (n=22), where cavities were lined with a conventional GIC (Vidrion F) and GA (n=23), with cavities lined with Vidrion F added with 1% each of metronidazole, ciprofloxacin and cefaclor antibiotic. Both groups were restored with Ketac Molar Easymix. Molars with carious lesions on the inner half of dentin without clinical or radiographic pulp damage were selected. Patients were evaluated clinically (pain, fistulas or mobility) and radiographically (area of caries, periapical region and furcation) after 1, 3, 6 and 12 months. For statistical analysis, chi-squared or Fisher's exact tests were used with a 5% significance level. GA (82.6-95.7%) had better results than GC (12.5-36.4%) in all evaluations (p<0.05) and the difference in the success rate was 46.2-72.5% higher for GA. The use of the antibiotic-containing GIC liner on infected dentin proved satisfactory when applied in deciduous teeth.

Os materiais dentários com propriedades antibacterianas podem proteger os efeitos nocivos causados por bactérias cariogênicas. Este ensaio clínico controlado duplo-cego avaliou o desempenho do cimento de ionômero de vidro (CIV) associado à antibióticos no selamento da dentina infectada em restaurações atraumáticas de molares decíduos. O estudo envolveu 45 crianças (45 dentes) entre 5 e 8 anos de idade, de ambos os sexos, divididos em dois grupos: GC (n=22), onde as cavidades foram forradas com CIV convencional (Vidrion F) e GA (n=23), onde as cavidades foram forradas com Vidrion F contendo 1% de cada um dos antibióticos metronidazole, ciprofloxacina e cefaclor. Ambos os grupos foram restaurados com Ketac Molar Easymix. Molares com lesões de cárie na metade interna da dentina, sem danos pulpares clínicos ou radiográficos foram selecionados. Os pacientes foram avaliados clinicamente (presença de dor, fístulas ou mobilidade) e radiograficamente (área de cárie, região periapical e de furca dos dentes), após 1, 3, 6 e 12 meses. Para a análise estatística o Qui-quadrado ou Exato de Fisher foram utilizados com 5,0% de significância. GA (82,6-95,7%) obteve melhores resultados do que GC (12,5-36,4%) em todas as avaliações (p<0,05) e a diferença na taxa de sucesso foi de 46,2-72,5% maior para GA. O uso do CIV com antibióticos no forramento da dentina infectada foi satisfatório em dentes decíduos.

Intralesional ciprofloxacin for cutaneous leishmaniasis: comparison with meglumine antimoniate

Leishmaniasis is quite commonly encountered in Balochistan. Of all the known treatment modalities, only a few are available at our hospital. We carried out this study in search of an effective and easily available agent. This quasi-experimental study was carried out at Combined Military Hospital Sibi in Balochistan from May to Nov 2010. The gross appearance of non healing ulcers and demonstration of parasite in Giemsa stained smears were used to confirm the diagnosis. Thirty nine patients were enrolled and divided into two groups by non- probability convenience sampling. Eighteen patients [having 30 ulcers] received meglumine antimoniate and 21 patients [having 32 ulcers] received 0.2% ciprofloxacin intralesionally every fifth day till re-epithelialization started, up to a maximum of five doses. Side effects of therapy were checked at every visit. Patients were followed up at one week and subsequently one month after completion of treatment to assess complete clinical healing and regression in size of the scar. Two ulcers in meglumine antimoniate and five ulcers in ciprofloxacin group did not heal [response rate 93.33% vs. 84.38%, p: 0.273]. Those treated with meglumine antimoniate required a lesser number of doses [mean 3.83 and 4.27; p: 0.039]. Reduction in scar size was equal in both groups [58.46% and 57.21%; p: 0.087]. Intralesional ciprofloxacin is an effective, cheap and safe treatment for cutaneous leishmaniasis

Time- and concentration-dependent cytotoxicity of antibiotics used in endodontic therapy

OBJECTIVE: New drugs have to be assessed in endodontic therapy due to the presence of microorganisms resistant to therapeutic procedures. Thus, this study evaluated the time- and concentration-dependent cytotoxicity of different antibiotics used in endodontic therapy. MATERIAL AND METHODS: Human gingival fibroblasts were treated and divided into the following experimental groups: Group I - control; Group II - ciprofoxacin hydrochloride; Group III - clyndamicin hydrochloride; and Group IV - metronidazole. Each drug was used at concentrations of 5, 50, 150, and 300 mg/L for 24, 48, 72, and 96 h. Cytotoxicity was evaluated by the MTT assay [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] and spectrophotometric reading of ELISA plates. The results were analyzed by BioEstat 4.0 software using Kruskal-Wallis and Dunn's tests at a signifcance level of 5 percent. Cell viability was assessed for the different concentrations and times. RESULTS: All drugs presented dose-dependent cytotoxicity. Concentrations of 5 and 50 mgjL produced viable fibroblasts at all experimental times in all groups. CONCLUSIONS: Cell viability at 24 h was greater than in the other experimental times. Comparison between the same concentrations of antibiotics at different times showed that metronidazole presented the highest cell viability at 72 and 96 h compared to the other antibiotics, whereas clyndamicin hydrochloride showed higher cell viability at 72 h than ciprofoxacin hydrochloride.

Comparison of 3-day and 7-day ciprofloxacin regimen for the treatment of uncomplicated urinary tract infection in women: a randomized double-blind clinical trial

Urinary tract infections [UTIs] are among the most commonly bacterial infections in clinical practice. Almost half of all women experience at least one urinary tract infection in their lifetime. This study compared efficacy and safety of 3-day and 7-day ciprofloxacin regimen for the treatment of uncomplicated urinary tract infection in women. A total of 76 patients were randomly assigned to two treatment groups. One group received ciprofloxacin, 250 mg twice a day for 3 days [n=39] and the other group received ciprofloxacin 250 mg twice a day for 7 days [n=37]. Subjects were visited and assessed three times during the study period [baseline, end of treatment, and test for cure]. Clinical and bacteriological responses to the treatment were compared between the two groups. There was no significant difference between the two groups in terms of age distribution and clinical signs/symptoms during the baseline visit. There was no significant difference between clinical or bacteriological responses between the two groups. Three-day regimen of ciprofloxacin showed high microbiological eradication rate for E. coli [66.7%] which was similar to the eradication rate observed for 7-day regimen [64.8%]. No statistically significant difference was found in adverse effects between the groups, except for nausea [p=0.041]. A 3-day ciprofloxacin regimen appeared to be safe and effective for the treatment of UTI in women. Therefore, shorter therapy duration with ciprofloxacin can potentially improve patient compliance and decrease costs

Toxic epidermal necrolysis and agranulocytosis: Rare adverse effects of ciprofloxacin.

Ciprofloxacin is one of the most commonly used antibacterial agents with relatively few side effects. Serious adverse reactions reported with ciprofloxacin are rare with an incidence of 0.6%. Recently we came across two rare adverse effects of ciprofloxacin, viz. toxic epidermal necrolysis and agranulocytosis. To our knowledge, a total of seven cases have been reported in the literature documenting an association between oral ciprofloxacin administration and toxic epidermal necrolysis. One case of granulocytopenia, four of pancytopenia and fifteen of leucopenia worldwide have been reported. With the use of ciprofloxacin becoming more and more widespread, these two rare but fatal complications of ciprofloxacin should be borne in mind.

Meningoencefalitis a salmonella: presentación de casos / Meningoencephalitis to Salmonella: presentation of cases

Se presentan tres pacientes con el diagnóstico de meningoencefalitis a Salmonella (D no typhi en dos y C2 en uno) ingresados en la Unidad de Terapia Intensiva de nuestro hospital desde 1989 a 2006. La evolución de los infectados con el tipo D no typhi fue más severa, presentando uno de los pacientes osteomielitis de tercio inferior del húmero al mismo germen luego de 14 días de tratamiento con cefotaxima y otro con recaída de la meningoencefalitis luego de 21 días de tratamiento con cefotaxima y ampicillín. Al igual que otros autores observamos una evolución más agresiva de la infección en estos enfermos comparados con otras meningoencefalitis bacterianas y se recomienda tratamiento con cefalosporina de tercera generación al menos por 4 semanas sola o en asociación con ciprofloxacina.

We present three inpatients with the diagnosis of meningoencephalitis to Salmonella (Non-typhi D in two and C2 in one) attended in the Intensive Care Unit of our hospital from 1989 to 2006. The evolution of the patients infected with the kind non-typhi D was more severe; one of the patients presented osteomyelitis of the lower third of the humerus to the same germen after a 14-days treatment with cefotaxime, and other had a relapse of the meningoencephalitis after 21 days of treatment with cefotaxime and ampicillin. Like other authors, we observed a more aggressive evolution of the infection in these patients in comparison with other bacterial meningoencephalitis, and recommend the treatment with third generation cephalosporin alone at least during 4 weeks or in association with ciprofloxacin.

Influência da ciprofloxacina na consolidação óssea de fraturas de fêmur em ratos / Influence of ciprofloxacin on femoral fractures healing in rats

OBJETIVO: Apresentar um estudo experimental sobre o efeito da ciprofloxacina na resistência do calo ósseo de fraturas padronizadas de fêmures de ratos. MÉTODOS: Os ratos foram separados em dois grupos de oito animais: o grupo estudo (cipro) e o grupo controle. Os animais foram submetidos à fixação dos fêmures esquerdos com fio metálico intramedular e à confecção de fraturas padronizadas no mesmo osso. O grupo estudo recebeu ciprofloxacina e o grupo controle soro fisiológico durante seis semanas. Após este período, realizou-se estudo radiográfico controle e ensaio biomecânico de três pontos para obtenção da força de flexão mensurada em Newtons. RESULTADOS: As radiografias e a análise macroscópica demonstraram consolidação óssea em todas as fraturas. Foram comparados os resultados encontrados no estudo biomecânico entre os dois grupos, sendo que o grupo cipro apresentou resistência à força de flexão média 71,11 e o grupo controle, força de flexão média 74,78, não apresentando significância estatística (p = 0,601, test t). CONCLUSÃO: Não houve diferença estatística significante na resistência do calo ósseo de fraturas padronizadas de fêmur de ratos após o uso de ciprofloxacina em relação ao grupo controle.

OBJECTIVE: To present an experimental study about the effects of ciprofloxacin on the bone callus strength on femoral fractures in rats. METHODS: The animals were divided in two groups of 8 rats each: the group study (cipro) and the control group. The animals were fixed with an intramedullary nail and submitted to a standardized femoral fracture. The group study was treated with ciprofloxacin and the control group with saline solution for six weeks. After that period, the femurs were analyzed using X-ray images and biomechanical three-point test, which measured the flexion strength in Newtons. RESULTS: The X-ray images and the macroscopic analysis showed that all fractures healed. The results found in the biomechanical study between the two groups were compared, and the cipro group presented a mean resistance to flexion force of 71.11 and the contol group, mean flexion force of 74,78. There was no statistically significant difference (p = 0.601, t-test). CONCLUSION: The results from the biomechanical tests performed on femoral fractures in rats receiving ciprofloxacin revealed no statistical significance from measures of callus flexion strength when compared to the control group.

efficacy of topical solution of 0.3% ciprofloxacin in treatment of mild to moderate acne vulgaris

Acne vulgaris is a very common disorder affecting virtually every adolescent at some point in time. Topical treatment of acne involves the use of retinoids and antimicrobials. Antimicrobials reduce P. acne population and are effective for treatment of inflammatory lesions. We evaluated the efficacy and safety of topical ciprofloxacin solution and compared it with topical erythromycin solution. The study was a prospective single-blind clinical trial. One hundred patients with mild to moderate acne were enrolled. The patients were randomly treated with topical application of 0.3% ciprofloxacin or 4% erythromycin solutions. For a six week period, they were visited every two weeks. Acne severity index [ASI] was calculated in each visit and recorded. Ninety-three patients completed the study, 50 patients in the ciprofloxacin and 43 in the erythromycin groups. Irritation was generally mild for both treatments and no discontinuation was reported because of adverse effects. There was no statistically significant difference between the two treatment groups in reduction of comedons or papules but reduction of pustules was greater in ciprofloxacin treatment group after 4 weeks. ASI was reduced in the two groups but in ciprofloxacin treated patients, this reduction was more significant at all follow up visits. The results of this study indicate that topical solutions of erythromycin and ciprofloxacin were effective in treating mild to moderate acne vulgaris and both were well-tolerated by the patients. Ciprofloxacin solution produced greater reduction in pustule counts and ASI, during the six week period of twice-daily application. This novel modality may have an important potential role in rotational topical therapy of inflammatory acne lesions
