Résumé

Objective: To compare the efficacy of fistulotomy versus fistulectomy in the treatment of low lying anal fistula in male patients


Study Design: Randomized clinical trial


Place and Duration of Study: Surgery Department, CMH Multan and CMH Malir, from Aug 2008 to Oct 2013


Patients and Methods: Study was done on 262 patients. Patients with anal fistula were divided by simple random allocation into groups A [fistulotomy] and B [fistulectomy]. The patients with simple low anal fistula without any comorbids were included in the study and the patients with recurrent fistula, high fistula or those having any comorbid were excluded from the study. Data was analysed using SPSS 17. Descriptive statistics applied for both quantitative and qualitative variables. Mean and standard deviation for quantitative and frequencies and percentages for qualitative data


Results: Total 262 patients were selected having low lying anal fistula and operated as group A - fistulotomy and group B - fistulectomy, each group constituted of 131 patients each. The operating time was found to be shorter for group A [14.29+3.24 minutes] and group B [25.92 +3.60 minutes]. The group A patients were discharged earlier [3.73 + 0.65 days] than group B [4.88 + 0.35 days]. In group A incidence of postoperative bleeding [0.8%], infection [2.2%] and recurrence was [10.7%]. While in group B bleeding [3.1%], infection [3.8%] and recurrence was [15.3%]. Severity of postoperative pain [as assessed by Numeric Rating Scale] was higher in group B as compared to group A. The healing time was shorter in group A [4.04 + 0.33 weeks] as compared to group B [4.57 + 0.497 weeks] and the patients of group A returned to normal activity earlier [10.9 + 2.05 weeks] than group B patients [15.54 + 0.51 weeks]


Conclusion: In male patients suffering from simple low lying anal fistulas, fistulotomy has a definitive superiority over fistulectomy and is recommended to be adopted as primary surgical modality for the treatment

Résumé

To evaluate the usefulness and safety of early versus late oral intake after appendectomy. Randomized clinical trial. Combined Military Hospital Multan from August 2008 to February 2009. One hundred patients with uncomplicated acute appendicitis, undergoing appendectomy under general anesthesia were included in the study and randomly divided into two equal groups. Early oral intake group [group A] was allowed fluids, when patients were out of effects of general anesthesia. Delayed fed [group B] was started oral fluids, on appearance of normal bowel sounds or passage of flatus. Low residue solid diet was started, after tolerance of oral fluids, in both groups. Early oral intake resulted in start of solid diet earlier by average 9 hours; these patients had normal bowel sounds, and passed flatus, earlier, after 4 hours and 5 hours as compared to late feeding group. Six [12%] patients had mild ileus in early fed group whereas 4[8%] patients in delayed fed group had mild ileus. Thirty eight [76%] early fed patients were very satisfied, as compared to 29 [58%] delayed fed patients. The hospital stay was prolonged by 2 days in delayed fed group. Early oral feeding implemented after appendectomy is safe and effective, with a shortened hospital stay as the primary benefit in patients after appendectomy

Résumé

To find out the frequency of Extensively Drug Resistant [XDR] and pre-XDR tuberculosis in clinical isolates of Multi-Drug Resistant [MDR] Tuberculosis [TB] by determining the susceptibilities against Levofloxacin and Amikacin [classical second line antituberculosis drugs]. A descriptive cross-sectional study. Microbiology Department, Armed Forces Institute of Pathology [AFIP], Rawalpindi, from September 2011 to August 2013. Amikacin [AK] and Levofloxacin [LEVO] were obtained in chemically pure form from Sigma [Taufkirchen, Germany]. The breakpoint concentration used for AK was 1.0 microg/ml and for LEVO 2.0 microg/ml. Mycobacterial Growth Indicator Tube [MGIT] 960 system was used to carry out drug susceptibility testing as per recommended protocol. A total of 3 MDR-TB isolates [3%] turned out to be XDR-TB based upon simultaneous resistance to injectable second line antituberculosis drug AK and one of the fluoro-quinolones [LEVO]. A total of 24 MDR-TB isolates [24%] were found to be pre-XDR based upon resistance to LEVO alone. Treatment status record of patients with XDR and pre-XDRTB isolates revealed that majority of patients had received fluoroquinolones [FQs] during the course of treatment. XDR-TB has started to emerge in MDR-TB isolates in our set up. The worrying sign is the high frequency of pre-XDR tuberculosis. Urgent steps need to be taken to stem the tide of pre-XDR-TB in our population. It is thus recommended to develop facilities to carry out drug susceptibility testing to monitor the status of pre-XDR and XDR-TB in our population

Résumé

To evaluate the in vitro effectiveness of multiple breakpoint concentrations of newer antituberculosis agents [Linezolid and Meropenem] against Multi Drug-Resistant Tuberculosis [MDR-TB] isolates. A descriptive cross-sectional study. Microbiology Department, Armed Forces Institute of Pathology [AFIP], Rawalpindi, from September 2011 to August 2013. A total of 100 MDR-TB isolates recovered during the study period were subjected to susceptibility testing against multiple breakpoint concentrations of Linezolid [LZD] and Meropenem [MER]. The breakpoint concentration used for LZD were 0.5, 1.0 and 2.0 microg/ml, while for MER were 4.0, 8.0 and 16 microg/ml. Mycobacterial Growth Indicator Tube [MGIT] 960 system was used to carry out drug susceptibility testing as per recommended protocol. At break point concentration of 0.5 microg/ml, 80 out of 100 [80%] MDR-TB isolates were susceptible to LZD while at breakpoint concentration of 1.0 microg/ml and 2.0 microg/ml, 96/100, [96%] of MDR-TB isolates were susceptible. For MER, at breakpoint concentrations of 4.0 microg/ml no MDR-TB isolate was susceptible, while at 8.0 microg/ml 3/100, [3%] and at 16.0 microg/ml 11/100, [11%] of MDR-TB isolates were susceptible. LZD was found to have excellent in vitro efficacy as 96% of MDR-TB isolates were susceptible at breakpoint concentration of 1.0 microg/ml or more. In case of MER it was found that in vitro susceptibility improved as the break point concentrations were increased

Résumé

To determine the antimicrobial susceptibility pattern of bacterial pathogens in the patients of urinary tract infection reporting at a tertiary care hospital. Laboratory based study. Department of Microbiology, Armed Forces Institute of Pathology, Rawalpindi, from January to December 2012. A total of 440 culture positive bacterial isolates from 1110 urine samples; submitted over a period of one year were included in this study. Identification of bacterial isolates was done by standard biochemical profile of the organisms. The antimicrobial susceptibility of culture positive bacterial isolates was performed by disk diffusion method as recommended by Clinical Laboratory Standard Institute guidelines [CLSI]. Out of the 440 culture positive urine samples, 152 [34.6%] were from indoor patients whereas 288 [65.4%] from outdoor patients. Gram negative bacteria accounted for 414 [94%] of the total isolates while rest of the 26 [6%] were Gram positive bacteria. The most prevalent bacterial isolate was Escherichia [E.] coli 270 [61.3%] followed by Pseudomonas [P.] aeruginosa 52 [12%] and Klebsiella [K.] pneumoniae 42 [9.5%]. The susceptibility pattern of E. coli showed that 96.2% of the bacterial isolates were sensitive to imipenem, 85.1% to amikacin, 80.7% to piperacillin/tazobactam and 72.6% to nitrofurantoin. In case of P. aeruginsosa, 73% bacterial isolates were sensitive to tazobactam/piperacillin, 69.2% to sulbactam/cefoperazone and 65.38% to imipenem. The antibiogram of K. pneumoniae has revealed that 76.1% of the bacterial isolates were sensitive to imipenem and 52.3% to piperacillin/tazobactam. Nitrofurantoin and imipenem were the most effective antimicrobials amongst the Enterococcus spp. as 92.3% showed susceptibility to this bacterial isolate. Majority of the bacterial isolates were sensitive to imipenem and piperacillin/tazobactam while susceptibility to most of the commonly used oral antibiotics was very low. Among the oral antimicrobials, nitrofurantoin showed good susceptibility against Enterobacteriaceae family and Gram positive organisms

Résumé

The purpose of this study was to assess the patient's awareness of informed consent and to evaluate the current practice of obtaining informed consent from patients proposed for elective surgery in tertiary care hospital. Cross sectional survey. This study was conducted in Isra University Hospital, Hyderabad, Sindh from 2[nd] April 2012 to 3[rd] March 2013. This study was designed as an observational investigation and no interference was made regarding the informed consent process to the patient. The selection criteria for the patients who were interviewed were convenience sampling. All adult patients of >18 years, who were undergoing various surgical procedures were interviewed after taking verbal informed consent on the second postoperative day, when they were comfortable to answer the questions. While all those patients who were uncomfortable due to pain or other reason and were unwilling to answer the questions were excluded from the study. All the patients were asked predesigned questions related to the information they were provided before the surgery as part of standard informed consent practice. Questions were asked in local language which includes the demographic data, operative details, risk, benefit, complications of surgery, type of anesthesia and alternative treatment options etc. The data was entered on SPSS version 16. Frequency and percentages were calculated to show the results. Mean age of the patients was 34.95 +/- SD 14.236 years. 220 patients were included in the study. 183[83.18%] patients were told about the indications of surgery while 136 [61.81%] patients were not told about any complication of Surgery. Type of anesthesia was discussed in only 25[11.36%] of patients while complications of anesthesia were discussed in only 18[8.18%] of patients. 165[75%] patients were not given time to ask the questions regarding their disease or surgery. Consent by the consultants was taken in only 63[28.63%] patients. The majority of the patients knew the indication of surgery but very few were informed about the possible complications and risk of the surgery and anesthesia

Résumé

To determine the usefulness of bone marrow aspiration and trephine biopsy in evaluation of the bone marrow in routine haematological practice. This study included 443 cases of bone marrow examination, referred to Pathology Department, Lady Reading Hospital Peshawar during the period extending from January 2012 till July 2013. All the bone marrow smears and bone biopsy sections were examined in detail. The diagnosis and findings on aspirate and biopsy were evaluated and compared with each other. In 73.8% of the cases the bone marrow aspiration and trephine biopsy showed same diagnosis i.e., bone marrow aspiration alone was sufficient for diagnosis in these cases. In the remaining 116 [26.2%] cases trephine biopsy sections or touch imprints were found to be necessary in for making final diagnosis. These cases were those of the hypoplastic / aplastic marrows, Myelofibrosis, lymphomatous infiltration and chronic granulomatous inflammation. The study results suggest that both the aspirate and trephine biopsy complement each other. Nutritional anaemias, Haematological Malignanciesand Immune Thrombocytopenia can be readily diagnosed by bone marrow aspiration alone. Trephine biopsy is necessary for diagnosing Granulomatous Inflammation and Hypoplastic/Aplastic Anaemia. Also trephinebiopsy is required to diagnose Myelofibrosis and Lymphomatous infiltration

Résumé

To determine the types of pathogens causing blood stream infections and their drug susceptibility profile in immunocompromised patients. Cross-sectional, observational study. Department of Microbiology, Armed Forces Institute of Pathology, Rawalpindi, from January to September 2012. Blood culture bottles received from immunocompromised patients were dealt by two methods, brain heart infusion [BHI] broth based manual method and automated BACTEC system. The samples yielding positive growth from either of two methods were further analyzed. The identification of isolates was done with the help of biochemical reactions and rapid tests. Antimicrobial susceptibility of the isolates was carried out as per recommendations of Clinical and Laboratory Standards Institute [CLSI]. Out of the 938 blood culture specimens received from immunocompromised patients, 188 [20%] yielded positive growth. Out of these, 89 [47.3%] isolates were Gram positive and Gram negative each, while 10 [5.3%] isolates were fungi [Candida spp.]. In case of Gram positive isolates, 75 [84.3%] were Staphylococcus spp. and 51 [67%] were Methicillin resistant. Amongst Gram negative group 49 [55.1%] isolates were of enterobacteriaceae family, while 40 [44.9%] were non-lactose fermenters [NLF]. In vitro antimicrobial susceptibility of Staphylococci revealed 100% susceptibility to vancomycin and linezolid. The enterobacteriaceae isolates had better susceptibility against amikacin 85.7% compared to tigecycline 61.2% and imipenem 59.2%. For NLF, the in vitro efficacy of aminoglycosides was 72.5%.The frequency of Gram positive and Gram negative organisms causing blood stream infections in immunocompromised patients was equal. Vancomycin in case of Gram positive and amikacin for Gram negative organisms revealed better in vitro efficacy as compared to other antibiotics.

Résumé

To determine the in vitro susceptibility of chloramphenicol against methicillin-resistant Staphylococcus aureus. Cross-sectional study. Department of Microbiology, Armed Forces Institute of Pathology, Rawalpindi, from January to June 2012. One hundred and seventy four isolates of methicillin-resistant Staphylococcus aureus were included in this study using cefoxitin [30 microg] disc for detection. Minimum inhibitory concentration [MIC] of chloramphenicol against MRSA was determined by using E-strip [AB BIO DISK]. The susceptibility was determined by swabbing the Mueller-Hinton agar [MHA] plates with the resultant saline suspension of MRSA and applying E-strip of chloramphenicol from AB Biodisk Sweden and determining the MIC of chloramphenicol [in microg/ml]. Clinical and Laboratory Standards Institute [CLSI] recommendations of /= 32 microg/ml as resistant were followed in interpreting the results. Out of the 174 MRSA isolates, 132 [75.86%] isolates were susceptible to chloramphenicol with MICs of A[2] 8 microg/ml, 38 [21.84%] were resistant >/= 32 microg/ml while 4 [2.30%] were in intermediate range with MIC of 16 microg/ml. Chloramphenicol has shown good in vitro activity against MRSA and is likely to have a key role in the treatment of MRSA infections providing us a good alternative to newer expensive antimicrobials in resource limited countries

Résumé

To determine antimicrobial susceptibility pattern of methicillin resistant Staphylococcus aureus in a tertiary care setting. Descriptive study. Microbiology Department, Armed Forces Institute of Pathology, Rawalpindi from March 2011 to April 2012. Two hundred isolates of MRSA recovered from various clinical specimens sent to AFIP for culture and sensitivity were identified using standard microbiological techniques and the antimicrobial susceptibility was carried out employing Kirby-Bauer disc diffusion technique as recommended by Clinical and Laboratory Standards Institute. The Susceptibility pattern of isolates was recorded in percentages. Of the 200 MRSA isolated, all[100%] were susceptiblr to vancomycin and Linezolid followed by 88% to tigecycline, 81% to chloramphenicol, 66% to amikacin, 62.5% to clindamycin, 52.5% to doxycycline, 36% to trimethoprim-sulfamethoxazole, 29% to gentamicin, 28.5% to erythromycin and 26.5% to ciprofloxacin. The results show that linezolid and vacomycin hold excellent in vitro efficacy against MRSA whereas doxycyline, clindamycin, trimethoprim-sulfamethoxazole, gentamicin, erthromycin and ciprofloxacin have poor sensitivity.

Résumé

To determine the role and pattern of non-dermatophyte moulds as causative agents of onychomycosis. Case series. Department of Microbiology, Armed Forces Institute of Pathology [AFIP], Rawalpindi, from November 2009 to July 2010. Nail clippings and nail scrapings were obtained from abnormal looking nails with treatment and detection failure for onychomycosis. Microscopic [40% potassium hydroxide mounts] examination and culture on Sabouraud's dextrose agar [SDA], SDA containing chloramphenicol, and SDA containing actidione and chloramphenicol were used for species identification. Non-dermatophyte moulds were isolated from 32 out of the total 47 culture positive cases [68%]. Alternaria alternata was the commonest species [46%]. Dermatophytes were isolated from only 7 patients [15%] belonging to genus Trichophyton. Yeasts were isolated in 8 [17%]. There was no fungal growth in 53% of cases. The non-dermatophytes should be considered important in evaluating the culture negative cases for dermatophytes as well as those cases ending up in treatment failure after empirical treatment for dermatophyte infections

Résumé

To determine the spectrum and antimicrobial susceptibility pattern of pathogens isolated from bone marrow transplant centre and to examine the evolution of bacterial resistance to antibiotics in these patients. It was a retrospective study conducted in the department of Microbiology, Armed Forces institute of Pathology [AFIP] from January 2004 to December 2009. Isolation, identification and antimicrobial susceptibilities were performed by standard methods. Gram negative bacterie accounted for 50.4% of the total isolates and Gram positives 49.6%. Escherichia coli was the most common isolate among the gram negative rods followed by Pseudomonas spp and Acinetobacter spp. Amongst the Gram positive organisms staphylococcus aureus and coagulase negative staphylococci followed by enterococci were the predominant organisms. The susceptibility of methicillin resistant staphylococcus aureus remained 100% for Vancomycin and Linezolid, while those of minocycline, fusidic acid and doxycycline were at an acceptable level of above 60%. Imipenem remained the most effective antibiotic for Gram negative rods. Acinetobacter spp. was the most problematic organism as only 62% isolates were susceptible to imipenem.
