Septate gall bladder: a surgical surprise with review of literature

Septate gallbladder is a rare congenital anomaly, which can present a challenge for the surgeon who performs laparoscopic cholecystectomy. The common first line modality for screening in symptomatic gallbladder pathology is still ultrasonography. Preoperative diagnosis of this anomaly is not common. Pre- operative diagnosis and being acquainted with this anomaly decreases the possibility of injury to the biliary tract, the number of postoperative complications and the possible need for further surgical procedures. We present a case of septate gallbladder, which was diagnosed during the operative procedure. Despite the finding of a septate gallbladder, the performance of laparoscopic cholecystectomy was uneventful.

Genital Chlamydia trachomatis: An update.

Chlamydia trachomatis is the most common cause of curable bacterial sexually transmitted infection (STI) worldwide. It manifests primarily as urethritis in males and endocervicitis in females. Untreated chlamydial infection in man can cause epididymitis and proctitis. Though most women with Chlamydia infection are asymptomatic or have minimal symptoms, some develop salpingitis, endometritis, pelvic inflammatory disease (PID), ectopic pregnancy and tubal factor infertility. It is associated with an increased risk for the transmission or acquisition of HIV and is also attributed to be a risk factor for the development of cervical carcinoma. Early diagnosis and treatment of infected individuals is required to prevent the spread of the disease and severe sequelae. Traditionally, tissue culture was considered the gold standard for the diagnosis. However, with the availability of newer diagnostic techniques particularly molecular methods which are not only highly sensitive and specific but are cost-effective also, the diagnosis has became fast and easy. The purpose of this review is to study the various aspects of genital C. trachomatis infection. Also the advances related to the clinical picture, various diagnostic modalities, prevention, treatment, drug resistance and control measures will be dealt with.

Needle stick injuries among health care workers in a tertiary care hospital of India.

Background & objectives: Percutaneous injuries caused by needlesticks, pose a significant risk of occupational transmission of bloodborne pathogens. Their incidence is considerably higher than current estimates, and hence a low injury rate should not be interpreted as a non existent problem. The present study was carried out to determine the occurrence of NSI among various categories of health care workers (HCWs), and the causal factors, the circumstances under which these occur and to, explore the possibilities of measures to prevent these through improvements in knowledge, attitude and practice. Methods: The study group consisted of 428 HCWs of various categories of a tertiary care hospital in New Delhi, and was carried out with the help of an anonymous, self-reporting questionnaire structured specifically to identify predictive factors associated with NSIs. Results: The commonest clinical activity to cause the NSI was blood withdrawal (55%), followed by suturing (20.3%) and vaccination (11.7%). The practice of recapping needles after use was still prevalent among HCWs (66.3%). Some HCWs also revealed that they bent the needles before discarding (11.4%). It was alarming to note that only 40 per cent of the HCWs knew about the availability of PEP services in the hospital and 75 per cent of exposed nursing students did not seek PEP. Interpretation & conclusions: The present study showed a high occurrence of NSI in HCWs with a high rate of ignorance and apathy. These issues need to be addressed, through appropriate education and other interventional strategies by the hospital infection control committee.

Enterococcal infections & antimicrobial resistance.

Enterococci have traditionally regarded as low grade pathogens, have emerged as an increasingly important cause of nosocomial infections in the last decade. Although about a dozen enterococcus species have been identified, only two are responsible for the majority of human infections, i.e., Enterococcus faecalis and E. faecium. The most common nosocomial infections produced by these organisms are urinary tract infections (associated with instrumentation and antimicrobial resistance), followed by intra-abdominal and pelvic infections. They also cause surgical wound infections, bacteraemia, endocarditis, neonatal sepsis and rarely meningitis. A major reason why these organisms survive in hospital environment is the intrinsic resistance to several commonly used antibiotics and, perhaps more importantly, their ability to acquire resistance to all currently available antibiotics, either by mutation or by receipt of foreign genetic material through the transfer of plasmids and transposons. The emergence of vancomycin-resistant enterococci (VRE) is a cause of concern, as once established, it is very difficult to control. Moreover, there can be transfer of resistant gene from enterococci to Staphylococcus aureus thereby posing a threat to the patient safety and also challenges for the treating physicians. This review highlights the shifting spectrum of enterococcal infections, along with their geographical distribution and growing nosocomial importance. Emergence of antimicrobial resistance, pathogenicity and virulence factors, current preventive, control and treatment modalities of severe enterococcal infections are also dealt with.

Profile of bacterial isolates from suspected cases of infective endocarditis (IE): a retrospective study in a north Indian tertiary care hospital.

Infective Endocarditis (IE) is an emerging infection of the twenty-first century. This chronic Infection is mainly caused by bacteria, although fungi can also be associated with it. It is Important to know the profile of bacteria causing IE in a given region so as to suggest the empirical therapy for this serious illness. Blood culture isolates of clinically diagnosed or suspected cases of IE admitted to various wards of the All India Institute of Medical Sciences were analyzed retrospectively from January 2000 to June 2004. Standard techniques were used for the isolation and identification of the bacteria. Our study has demonstrated the predominance of Gram-negative bacilli, especially, Acinetobacter species and Pseudomonas aeruginosa, which are notorious for antimicrobial resistance, as the aetiological agents of IE. Amongst Gram-positive cocci, Enterococci exhibiting HLAR comprised the predominant species. Methicillin resistance among staphylococcal strains in this Tertiary care hospital is adding to the therapeutic challenge in the management of this serious illness. Although antimicrobial treatment should not be delayed in such cases, we cannot undermine the importance of isolation and identification of the etiological agents and the determination of the antimicrobial susceptibility for the management of these life-threatening conditions as well as for the formulation of guidelines for empirical therapy of these cases.
