A. Clinical presentation advanced carcinoma of the sigmoid colon may present as obstruction, perforation, bleeding, or colovesical colovaginal fistula. This may sometimes be confused with sigmoid diverticulitis, even at operation. Furthermore, diverticular disease is present in 20% of patients with colon cancer. At operation, liver metastases may be appreciated and may or may not change the operative strategy. Obstruction occurs in approximately 15-20% of all colorectal cancer patients, whereas perforation occurs in about 3-9%. Roughly 2 3 will have localized perforation and 1 3 will have free perforation with generalized peritonitis. b. Diagnosis Lower endoscopy with biopsy, contrast studies of the colon, and CT of abdomen pelvis are commonly used. Urine analysis will reveal the presence of colovesical fistula with bacterial contamination and hematuria. If perforation is suspected, gastrograffin should be used instead of barium. The entire colon should be inspected if possible for the presence of synchronous lesions. In certain cases, contrast study can examine the rest of the colon even if the lesion does not allow the passage of an endoscope. If the lesion is completely obstructing, care palpation intra-operatively and early post-operative endoscopy should be done. If the CT scan reveals liver metastases, MRI should be ordered to better define these lesions and or reveal the presence of other smaller mets. c.

Ated. They have also now been abandoned because of unacceptably low eradication rates. The newer dual drug regimen of ranitidine bismuth citrate RBC ; and clarithromycin for two weeks has shown few side effects and has a superior eradication rate compared to other dual therapies10. However, it has still not been widely evaluated. Overall dual therapies are not very much in current use for eradication of H. pylori due to low eradication rates. Triple drug therapy Bismuth based triple therapy pioneered by Borody et al consisting of colloidal bismuth subcitrate 120 mg, q.i.d ; , tetracycline 500 mg, q.i.d ; and metronidazole 400 mg, t.i.d ; for two weeks is cheap, well investigated and ensures high cure rates in metronidazole sensitive strains2, 11. This therapy has the advantage of both luminal and systemic activity. Bismuth precipitates in and around H. pylori and also collects beneath the bacterial cell wall leading to the detachment and lysis of the organism within two hours of ingestion of this drug12, 13. Tetacycline is acid stable and achieves high concentrations in the gastric mucosa. This therapy is still the treatment of choice in many Western countries due to a low resistance of H. pylori to nitroimidazoles in those countries. An early meta-analysis by Chiba et al showed the highest eradication rate with this regimen to be 94%8. When tetracycline was replaced by amoxicillin in this regimen the eradication rate dropped to 73%14. This therapy may cause side effects, but these are usually not severe and usually do not lead to noncompliance. In our experience with bismuth based classical triple therapy, nausea and diarrhea was present in 37% and 21% of patients but this did not lead to discontinuation of therapy 15. Probiotic supplementations have been tried to reduce such drug related manifestations. Armuzzi et al reported a significant reduction in the side effects like diarrhea, nausea and taste disturbances when Lactobacillus GG was supplemented with the anti microbial regimen16. Even though bismuth based triple therapies have high and acceptable eradication rates in areas with low nitroimidazole resistance, in developing countries, the response to this therapy is low as 80-90% of H. pylori strains are resistant to metronidazole17, 18. Such a high primary resistance rate is due to the availability!

Herba Andrographidis compared with 36% of the placebo group. Also 55% of the treated patients thought that the course of illness was much easier than normal, as compared with 19% of the placebo group 18 ; . A randomized, placebo-controlled, double-blind study evaluated a standardized extract of the aerial parts containing 4% andrographolides ; in the prophylaxis of the common cold in 107 schoolchildren during the winter season. The children received either 200 mg extract or a placebo daily for 3 months and were evaluated weekly by a physician. There was no difference in the occurrence of colds between the two groups during the first 2 months of treatment. However, after the third month of treatment, there was a significant difference P 0.05 ; in the occurrence of the common cold in the treated group 30% ; as compared with the placebo group 62% ; 19 ; . A randomized, double-blind comparison study of 152 adult patients with pharyngotonsillitis evaluated the efficacy of powdered aerial parts 6 g daily ; and paracetamol 1 capsule of 325 mg as needed ; for improving symptomatology. Baseline evaluation showed no significant difference between the two groups. The crude drug was as effective as paracetamol in reducing the incidence of sore throat and fever after 3 days of treatment 20 ; . In study without controls, treatment of patients with a standardized extract of A. paniculata containing 4% andrographolides ; reduced the incidence of fever associated with the common cold. The body temperature of patients treated with the extract was lowered in less than 48 hours after treatment 55 ; . This finding was confirmed in a later study 17 ; . Urinary infections A clinical trial compared the efficacy of Herba Andrographidis, co-trimoxazole sulfamethoxazole + trimethoprim ; and norfloxacin in the prevention of urinary tract infections after extracorporeal shock wave lithotripsy. Patients received a 5-day course of either Herba Andrographidis 4 tablets of 250 mg, three times daily ; or co-trimoxazole 2 tablets of 25 mg, twice daily ; or norfloxacin 1 tablet of 200 mg, twice daily ; . After 1 month of treatment, urinalysis results of 100 patients demonstrated that pyuria, haematuria and proteinuria were reduced in all treatment groups, and there was no significant difference between the three treatments 21 ; . Dysentery The aerial parts have been used for the treatment of acute bacillary dysentery and enteritis 2, 6, 22, ; . In clinical studies, the combination of andrographolide and neoandrographolide was reported to be more effective than either furazolidine or chloramphenicol in the treatment of bacillary dysentery 6 ; . A randomized, double-blind clinical study of 200 patients compared the efficacy of the powdered aerial parts with tetracycline in the treatment of acute diarrhoea and bacillary dysentery 22, 23 ; .

Methamphetamine is an addictive stimulant drug that strongly activates certain systems in the brain. Methamphetamine is closely related chemically to amphetamine, but the central nervous system effects of Methamphetamine are greater. Methamphetamine is made in illegal laboratories and has a high potential for abuse and dependence. The drug can be taken orally, injected, or inhaled. Acute higher doses lead to enhanced stimulation of the central nervous system and induce euphoria, alertness, reduced appetite, and a sense of increased energy and power. Cardiovascular responses to Methamphetamine include increased.
The frequency, nature and severity of adverse events did not differ significantly from those experienced with placebo. The most commonly reported adverse events were headache, nausea and diarrhea and doxycycline.

The form is to be tested for comprehension of concepts and pictures. As pictures will most often be reproduced on the form in a much reduced size from A4 ; , it is important to assess carefully how small the pictures can be and still be easily understood. Here it is essential to also test the form in a "new" community, as people in the original community will already be familiar with the pictures from the pretest ; , and will most likely recognize at least some of them. If the results show that big revisions have to be made on the form, a second pretest would be necessary. See chapter 3.4 for detailed guidelines on how to pretest the form: this is one of the most important steps in the research process and ethionamide.

Reversible inhibition of the enzyme and reduction of gene transcription.16 In addition to these effects, doxycycline decreases the levels of interleukin IL-1 , IL-1 , IL-6 ; 17 and nitric oxide synthase, 18 which may act to reduce proteolytic activity, as well as having effects on arterial diameter and vessel wall fragmentation.19 To be effective in reducing MMP activity in vascular lesions, doxycycline must be efficiently delivered to the tissues. Previous studies have demonstrated that tetracyclines localize to atherosclerotic plaques. Franklin et al20 revealed that tetracycline rapidly penetrated the aortic wall and achieved a median concentration of 2.9 g g tissue wet weight, which was sufficient for biological activity. In the present study, 200 mg d of orally administered doxycycline resulted in a mean concentration of 6.1 g doxycycline g wet weight of carotid plaque and a serum level of 3.5 g ml. Recent observations from Prall et al21have suggested that doxycycline concentrations 2 g ml are likely to be effective in reducing MMP concentrations in clinical studies.

Two vendors in the Specialty Pharmaceuticals segment provided approximately 27% of total product purchases during the year ended September 30, 2005. They are as follows and levaquin. Tetracycline is currently the drug of choice for serious vibrio infections 10, 14 ; . Since 1978, however, an increasing number of Vibrio cholerae 01 strains have been identified that have plasmid-mediated resistance to multiple antibiotics, including tetracycline. These strains have been responsible for major epidemics in Tanzania 9 ; and Bangladesh 7 ; and are currently endemic in parts of Africa J. G. Morris, K. L. Richardson, J. Michalski, A. C. Wright, J. B. Kaper, J. N. Kaviti, S. Kinoti, A. J. Mohamed, J. Turkish, and M. M. Levine, Program Abstr. 24th Intersci. Conf. Antimicrob. Agents Chemother., abstr. no. 503, 1984 ; . Appearance of these strains has prompted a search for alternative antimicrobial agents with activity against vibrios. Norfloxacin is a new carboxyquinoline derivative that has in vitro activity against a number of enteric pathogens, including campylobacter, salmonella, shigella, toxigenic Escherichia coli, yersinia, and, in testing involving a limited number of strains, V. parahaemolyticus and V. cholerae 4, 8, 11, ; . In vitro activity against V. cholerae 01 would make norfloxacin an attractive drug for further study in areas with tetracycline-resistant cholera. Demonstration of activity against the other known pathogenic Vibrio species would also enhance the potential usefulness of norfloxacin as a broad-spectrum agent for treatment of bacterial gastroenteritis. In this study we compared the in vitro activity of norfloxacin to that of nalidixic acid, tetracycline, chloramphenicol, ampicillin, trimethoprim-sulfamethoxazole, and gentamicin against 93 vibrio strains representing all known pathogenic Vibrio species 10 ; . This work was presented in part at the 24th Interscience Conference on Antimicrobial Agents and Chemotherapy, Washington, D.C., 8 October 1984. ; Strains included 29 V. cholerae 01, 11 non-O1 V. cholerae, 22 V. parahaemolyticus, 19 V. vulnificus, 4 V. hollisae, 1 V. fluvialis, 2 V. furnissii, 2 V. damsela, 1 V. metschnikovii, 1 V. mimicus, and 1 V. alginolyticus. V. cholerae 01 isolates were from nine different countries in Africa, Asia, Europe, and North America; 13 had an R factor coding for one of four different antibiotic resistance patterns. From storage at -70C, strains were plated on L agar 10 g of tryptone per liter [Difco Laboratories, Detroit, Mich.], 5 g of yeast extract per liter, 10 g of NaCl per liter, 15 g of agar per liter ; and thiosulfate citrate bile-salts sucrose agar to check for purity. Species identification was confirmed.

Adolescent Acne By Lisa Kimmey-Walker, MSN, RN, CPNP, Pediatric Nurse Practitioner, Memorial Hermann Health Centers for Schools and member of the Center for Technical Assistance and Training Advisory Panel Pimples! Why me? Since about 80% of teens get acne vulgaris to some degree and all acne is hormonal, chances are you will have the opportunity to help a student with this problem. Lets start with an anatomy review. The high levels of hormones in teens lead to an increase in sebum oil ; production, which can clog hair follicles pores ; and lead to pimple formation. This occurs usually about one to two years prior to the onset of puberty so the "tweens" pre-teens ; may also be affected. The sebum can combine with dead skin cells and dirt on the skin. Pimples may become infected and lead to pustules. The bacteria are propionibacterium acnes. "Blackheads" have oxidized melanin that lead to the darker color. Stressful events can worsen acne and genetics certainly contribute to likelihood and degree of acne. Providers should also incorporate assessment for creatine or anabolic steroid use in students with a history of severe acne. Education is key in the management of this condition. Reassurance that acne is not diet related and is manageable is important in preserving or restoring self-esteem. Affected areas of the face, back, or chest should be washed two or more times daily to remove the excess sebum. Soap and water or OTC Salicylic acid acne washes can be used. To minimize scarring, the teen should not traumatize the lesions in any way, including the use of adhesive strips to clean out pores. Patience is not typically associated with adolescents, but help them "hang in there" since improvement takes months, not days. And the bad news. Once initiating treatment, the acne frequently gets worse before it gets better, resulting in premature cessation of therapy and failure to keep follow-up appointments. Adolescents need a good support system and regular feedback. Serial photographs help document progress whether by the student or clinician. There are many medications available for the treatment of acne in various presentations. Benzoyl peroxide BPO ; has antimicrobial activity against propionibacterium. acnes and is available in 2.5%, 5% and 10% strengths OTC. It is very effective with mild acne and as a combination therapy for moderate acne. The American Academy of Pediatrics recommends starting with the lowest doses for initial management of acne. There are a variety of prescription medications for acne available including topical and systemic antibiotics. A topical agents like Tretinoin Retin A ; is used with mild to moderate acne. Retin A cream should be the initial therapy with progression to the gel if needed. The newer micro gel is less irritating. Moderate to severe acne may be treated with Benzamycin BPO + erythromycin ; and Benzaclin BPO + clindamycin ; alternating with Retin A to avoid systemic antibiotics. Benzamycin must be refrigerated. Erythromycin gel is an inexpensive topical solution option for mild to moderate acne. Systemic or oral antibiotics used to treat moderate to severe acne are tetracycline, erythromycin, minocycline, clindamycin, trimethoprim sulfamethoxazole Bactrim ; , and isotretinoin Accutane ; . The pros and cons of each drug should be discussed with both the student and family. For example, Minocycline can cause a lupus- like skin reaction, Tetracgcline and Accutane are teratogenic harm fetuses ; and Bactrim can cause a severe allergic reaction Stevens-Johnson ; . A depression assessment is needed prior to initiation of Accutane. Oral contraceptives must be free of norgestrel, norethindrone and norethindrone acetate as these hormones exacerbate acne and trimox.
And 103 colony-forming units for H. ducreyi and S. aureus strains, respectively. The MICs were performed in duplicate on 103 local isolates, and H. ducreyi ATCC 27722 and S. aureus ATCC 25923 were included as control organisms in all tests. Twofold serial dilutions of the drugs tested were made in the appropriate agar base covering a range of concentrations from 0.0001 to 128 jig ml. All plates were examined after 24 h of incubation, and the MIC was taken as the lowest drug concentration allowing growth of three colonies or less. , B-Lactamase production was demonstrated by the chromogenic cephalosporin degradation method 15 ; . Results are summarized in Table 1. The MICs of S. aureus ATCC 25923 not recorded ; were within the expected ranges. Resistance to penicillin and ampicillin was the result of P-lactamase production. Ninety-six isolates 93% ; produced this enzyme, including eight isolates with relatively low MICs of 4 to ml. None of the P-lactamase-negative strains had MICs over 0.5 pug ml. With the advent of efficient media for the isolation 5 ; and susceptibility testing of H. ducreyi 6 ; , more reliable studies have become possible. Hammond et al. 6 ; found 19 strains from Winnipeg, Canada, to be susceptible to rifampin, chloramphenicol, sulfisoxazole, and nalidixic acid, three isolates being resistant to penicillin and ampicillin as a result of a TEMtype P-lactamase 1, 11 ; . Only one strain, also 3lactamase producing, was resistant to both tetracycline and doxycycline. South African and Kenyan strains H. Nsanze, personal communication ; are resistant to ampicillin, tetracycline, and sulfonamides, but susceptible to erythromy. Government authorities in the United States, at the federal, state, and local level, and foreign countries extensively regulate, among other things, the research, development, testing, manufacture, labeling, promotion, advertising, distribution, sampling, marketing, and import and export of our proposed products. All of our product candidates will require regulatory approval by government agencies prior to commercialization. In particular, human therapeutic products are subject to rigorous preclinical and clinical trials and other approval procedures of the FDA and similar regulatory authorities in foreign countries. Various federal, state, local, and foreign statutes and regulations also govern testing, manufacturing, safety, labeling, storage and record-keeping related to such products and their marketing. The process of obtaining these approvals and the subsequent substantial compliance with appropriate federal, state, local, and foreign statutes and regulations require the expenditure of substantial time and financial resources and zithromax!

About 40% of the strains had decreased sensitivity to -lactams. There was nearly double the number of strains as compared to last year 22% in 2004 ; . Two resistance mechanisms could be incriminated: in about 24% of the cases there was secretion of a lactamase and in 15% of the cases there were changes to the PLP penicillin liaison proteins ; . It should be noted that strains that produced -lactamase were still sensitive to the amoxicillin + clavulanic acid combination. As far as changes to the PLP were concerned, they conferred a low level of resistance to all -lactams. While resistance through secretion of a -lactamase is common in metropolitan France, i.e. between 30% adults ; and 50% children ; , resistance through PLP changes is still rare, i.e. 5%. So the frequency at which such strains were isolated in French Polynesia in 2005, i.e. 15%, should be confirmed and monitored. In contrast, whatever the mechanism might be, all the strains were sensitive to third-generation cephalosporins Cefotaxim ; . Apart from kanamycin, there was still good sensitivity to the other antibiotics tested, i.e. gentamicin, tetracycline and fluoroquinolones.

Almut Winterstein of the University of Florida, USA, dealt with occurrence of medication errors. Almut started her presentation by giving an example of a drug that was withdrawn from the market due to inappropriate prescribing. Cisapride was withdrawn from the market because the drug could not be used safely due to its interaction with macrolides. From a review of drugs involved in medication errors, Almut showed that psychotropic drugs, cardiovascular drugs and analgesics are the most common and that the common adverse effects are allergic reactions, hepatic damage, renal damage and cardiovascular effects. The causes for medication errors included inappropriate prescribing decisions and inappropriate patient monitoring. Hence reduction of medication errors requires professional input and not only relying on the use of information techonologybased distribution and administration of drugs. Almut showed that a major problem in hospitals is uncontrolled infections due to under-prescribing of anti-infective agents or failure of anti-infective agents. She concluded that in the hospital setting pharmacists should review medication so as to prevent occurrence of hypoglycaemia or hyperglycaemia, acute renal impairment, thromboembolic and haemorrhagic events, and uncontrolled infections and cipro and Order tetracycline.

The commensal intestinal microbiota of humans and animals may act as a reservoir of antibiotic resistance genes that could ultimately be transferred to pathogens 15, 18 in fact, gene transfer between bacterial species in the gastrointestinal tracts GIT ; of mammals is known to occur 11 ; . Bifidobacteria are among the dominant populations of the human GIT microbiota, where they are thought to play a pivotal role in maintaining the microbial balance necessary for intestinal health 19 ; . Bifidobacterial strains are therefore frequently used as probiotics in the prophylaxis and therapy of GIT disorders 12 ; . This practice, however, requires that they be screened for acquired antibiotic resistance determinants if the latter are not to be propagated through the food chain 14, 15, 18 ; . Tetracyclines inhibit protein synthesis by preventing the attachment of aminoacyl-tRNA to the bacterial ribosome 2 ; . The broad-spectrum antimicrobial properties of these agents, the absence of major adverse side effects, and their low price have led to their intensive use not only in the treatment of human and animal infections but also as prophylactic agents and growth promoters in livestock raising and aquaculture 2 ; . This extensive use has promoted the appearance of resistance and its spread by horizontal acquisition 2, 13 ; . Resistance is mediated through efflux proteins, ribosomal protection proteins, or antibiotic-inactivating enzymes for a review, see reference 13 ; . The tet W ; gene, which encodes a ribosomal protection protein, has recently been described for a wide range of gram-positive and gram-negative bacteria 1, 2 ; , including bifidobacteria 7, 10, 17 ; . This gene has been associated with a conjugative transposon TnB1230 ; in Butyrivibrio fibrisolvens 9 ; that has been shown to transfer at high frequencies up to 5.1 10 3 transconjugants per recipient ; 16 ; .

Antimicrobial Therapy Antimicrobial therapy is an important adjunctive therapy in cholera, whether caused by O1 or O139 strains 371, 418 Table 37-8 ; . Duration of illness and stool volume losses can be cut in half with oral not parenteral ; antibiotics. In addition, the duration of excretion of V cholerae is also shortened to an average of 48 to hours with antibiotics.418 Tertacycline or doxycycline are the recommended first-line drugs. For children less than 8 years of age and pregnant women, erythromycin, furazolidone, or trimethoprimsulfamethoxazole TMP-SMX ; are indicated. In areas where there has been significant resistance reported, quinolones such as norfloxacin or ciprofloxacin can be used.416, 419422 Quinolones have great advantages in that they are effective as single-dose therapy and the rate of clearance of V cholerae from stools is faster than with tetracycline or furazolidone treatment.419, 420 This rapid clearance of the stools may help to reduce secondary transmission of cholera, especially in hospi.

The closest relative to Tet 37 in the database is from Fusobacterium nucleatum subsp. nucleatum strain ATCC 255 GenBank accession number AE010563.1 ; , with 44% identity. A multiple alignment of Tet 37 with other oxidoreductases is presented in Fig. 1 and shows conserved motifs between Tet 37 and these oxidoreductases. The enzymatic activity of E. coli cell extracts containing tet 37 ; was determined. There was a marked decrease in the prominent peak in the tetracycline absorbance spectrum at 365 nm after incubation for 90 min Fig. 2 ; , indicating inactivation of tetracycline. A decrease in absorbance was also observed when cell extracts containing tet X ; were used, confirming the observations of Speer and Salyers 3 ; . There was no such decrease when cells containing the vector alone were used Fig. 2 ; . When intact cells containing the tet 37 ; gene were used instead of cell extracts, no reduction in the absorbance at 365 nm occurred. Incubation of NADH alone with disrupted cells resulted in a decrease in the height of the NADPH peak at 290.

Table 45. Prevalence in Families of Patients With Abdominal Aortic Aneurysms AAAs. This double issue of HTB includes additional reports from the EACS and ICAAC conferences held at the end of 2005 plus our usual round-up of articles on treatment access and related treatment news. Most notable, has been the decision to stop the international SMART trial on safety reasons, based on a DSMB recommendation in January. From the limited information released so far, it appears that the main question of whether there are benefits of treatment interruptions as outlined in the SMART protocol that outweigh the risks, has been answered after less than two of the planned nine years follow-up. An interim safety analysis requested by the DSMB showed a greater number of AIDS events including deaths in the treatment interruption arm compared to the continuous treatment arm. After seeing unblided data the SMART Executive Committee agreed with the recommendation from the DSMB. With almost 5500 patients recruited, the study was sufficiently powered to determine that these differences were highly statistically significant after such short follow-up. Please see the Antiretrovirals section of this issue of HTB for important details and news. Further speculation on the results will be dependent on public access to the data, which will be at a late breaker presentation at the 13th Conference on Retroviruses and Opportunistic Infections in Denver in a couple of weeks. Full details, and our own analysis, will be reported after this presentation, together with other news from CROI, in the next issue of HTB. With distribution of this issue of HTB, we have included single copies of our new leaflet, poster and postcards, publicising the i-Base Treatment Information Service. The service provides a free telephone information line, staffed by HIV positive advocates who are experts in HIV treatment. We offer the latest treatment information to a range of HIV positive people, their families and carers. We also send individually tailored printed information as follow up also free of charge ; , and when requested, and if appropriate, can advocate directly for people who need additional support in negotiating the health system. These materials have been developed with a wide consultation group and they represent part of a re-branding of this service. Although not included in the information, in addition to taking calls in English, support is also available in Russian, Bulgarian and Japanese. We hope that you like the new look and will want to publicise our services to those who need them. We estimated 10 year baseline Medicare spending at 0 million; incremental Medicare spending under the proposal of .9 billion, with a 10 year net cost of the proposal of .5 billion. The baseline estimate of DXA procedures is 6.1 million 4 million over five years ; , with the proposal recovering 11.8 million DXA procedures.

The result was negative. After 10 days of antimicrobial drug therapy, the wound had not improved. He was hospitalized, and the infected finger was incised and drained. An orthopedic specialist diagnosed infectious tenosynovitis of the flexor tendon of the left index finger. The initial slide preparation was negative for AFB. A wound culture was sent to Michigan Department of Community Health, Bureau of Laboratories. The patient was discharged and then readmitted to the hospital 12 days later with subcutaneous infection at the puncture site, which was again incised and drained. A slide made of growth from the broth culture medium was positive for AFB. Genetic probe results confirmed M. tuberculosis complex. By December 7, 2004, the culture was reported as resistant to pyrazinamide, suggesting M. bovis, which was later confirmed on the basis of susceptibility to thiopene-2-carboxylic acid hydrazide and biochemical testing for pyrazinamidase. The result of a second skin test, 14 weeks postexposure, was positive 6-mm induration.

The EBA was calculated from the mean daily fall in CFU ml sputum during the 2-d period of drug administration S3 log10 CFU ml S1 log10 CFU ml sputum ; 5, 7 ; . The means, their 95% confidence limits, and the standard deviations SD ; for each treatment group were calculated using EXCEL worksheets Microsoft Corp. ; . Differences between the EBAs of treatment groups and multiple regression analysis was done using EPIINFO 6 8 ; . The dosage effect of CIP in Phase I was determined with a nonparametric trend test across ordered groups 9 ; in the STATA package release 4, Stata Statistical Software, TX ; . In addition to calculation of the EBA, standardized CFU counts, without logarithmic transformation, were calculated as the S3 S1 ratio and were reported as percentages. For comparison of the various treatment regimens with the control Nil ; regimen, point estimates of the ratio of their standardized counts together with nonparametric 95% confidence limits were calculated using a SAG macro in the SAS statistical package 1995. Were negative. No statistical association was found Chi squared test, P 0.898 ; . Mycobacterium marinum is found in fresh or salt water, or fish, thus fishermen and those who keep fish are at higher risk. Patients in our series who had contact with fish were fewer compared with other series.3, 6, 8 This may be due to underreporting, wearing gloves when cleaning an aquarium or handling fish, or just a smaller fishing industry in Hong Kong. There was no statistical association between trauma history, fish contact, and culture result in M marinum infection. Oral tetracycline, most often minocycline, was prescribed for most patients in this series. Only four patients reported transient mild adverse effects with tetracycline that demonstrated high efficacy and a low side-effect profile. We concur with other reports that tetracycline monotherapy, especially minocycline, is an effective and safe treatment for immunocompetent patients with M marinum skin infection.12, 13 Cotrimoxazole-trimethoprim3, 6 and anti-TB drugs3, 7 are also effective in M marinum and MAI infections. Mycobacterium chelonae is resistant to traditional anti-TB drugs.14 Clarithromycin monotherapy has been reported effective in M chelonae cutaneous infection in immunocompetent11 and immunocompromised subjects, 15, 16 and has also demonstrated in-vitro activity against other atypical mycobacteria such as MAI and M marinum.17 The clinical response may nonetheless not correlate with in-vitro antimicrobial susceptibility results.18 In our series, three patients responded to antibiotics to which the organisms showed in-vitro resistance two MAI ; or that were not tested M chelonae ; . The antimicrobial susceptibility test serves as a guideline for management. Therapeutic agents should be chosen based on the known susceptibility pattern of the specific species and adjusted if necessary according to the clinical response and the final sensitivity results. Local hyperthermic therapy has also been reported useful in treating infections.19, 20 There were limitations to this study. We included only patients with skin infections who attended our dermatological clinics. This may not reflect the complete epidemiological picture in Hong Kong since some patients present to other specialties such as orthopaedic surgery. Nonetheless, this study was conducted in the largest dermatological referral centre in Hong Kong, it undoubtedly provides useful information about skin infections in the region. In addition, if PCR for non-tuberculous mycobacteria was available, the diagnostic accuracy could be enhanced and more confirmed cases could be identified. Question 2. What is the most likely basis of metabolic acidosis in this patient? Physiology principle 2. One can deduce that H ions have been added when new anions appear in the body and or in excreted fluids.
