BACKGROUND AND AIMS: Certain routine pre-operative laboratory investigations are performed in all patients before elective surgeries. We conducted this study to assess the value of routine pre-operative tests in the ASA (American Society of Anesthesiologists) Grade I and II adults undergoing elective surgery and their influence in the conduct of anaesthesia together with the costs incurred on unwarranted tests. METHODS: A total of 1271 patients posted for elective surgery under anaesthesia were recruited. Each patient attended the Pre-Anaesthetic Checkup Clinic and underwent clinical evaluation and investigations according to institutional policy. Demographic data and other characteristics were recorded, along with the results of laboratory test, any peri-operative intervention done as a result of abnormality and the cost incurred on tests. RESULTS: Majority of the patients belonged to ASA status I (74%) and underwent moderately invasive surgery (78%). The total number of routine investigations performed was 8015. Of these, 351 (4.37%) tests had abnormal results. Amongst these 333 (4.15%) abnormalities were suspected clinically and peri-operative intervention was only performed in 0.43% of patients. Anemia was the most common abnormal finding. Abnormal blood glucose was detected in 6 patients who were not clinically suspected. Abnormal electrocardiograph (ECG) was found in 54 patients. However, the intervention was required only in 13 patients. No intervention was required because of abnormal findings of the chest X-Ray. In total cost of investigations, only 6.9% was contributed by abnormal investigations and the rest was spent on the normal tests. CONCLUSION: The incidence of tests with abnormal results was very low in our study, and less than 1% of the patients with abnormal tests required changes in their peri-anaesthetic management. No major complications were seen in any patient with normal or abnormal test results. Most of the expenses (93%) were related to the normal test, which did not contribute to the perioperative management, safety and outcome of the patient. Thus, pre-operative investigations should be judiciously advised to avoid inconvenience, surgical delays and escalation of the costs of surgical care.

Uterine leiomyomas (fibroids) are the most common tumor of the reproductive system in women between menarche and menopause. Uterine lipoleiomyomas are a rare variant of leiomyoma, consisting of smooth muscle cells admixed with adipocytes.Herein is the case of a 70-year-old female who presented with acute pelvic pain and a palpable pelvic mass. A computed tomography scan of her abdomen and pelvis demonstrated a large, circumscribed, fat and soft tissue density, uterine mass suggestive of a lipoleiomyoma. Histopathology examination of the resected specimen after total abdominal hysterectomy confirmed a mature lipoleiomyoma.

Regular and continual monitoring of the disinfection protocol of the water distribution system in haemodialysis unit is necessary to get good microbiological quality of treated water and dialysate fluid.

Background Syphilis among men who have sex with men (MSM) living with HIV is of public health concern, thus the objective of the study is to determine the correlates of prevalent syphilis infection in this population so that urgent interventions could be instituted. Methods A cross-sectional study was conducted during the period September 2020-June 2021 among MSM who attended a large HIV Clinic in Trinidad. A questionnaire was administered to obtain socio-demographic data and correlates of prevalent syphilis and patients were screened for syphilis using the traditional algorithm. Descriptive and bivariate analyses were conducted and multivariable logistic regression factors was used to assess factors significantly associated with a syphilis diagnosis. Results Two hundred and sixty four MSM were enrolled; age range 18–64 years, median age 33 years and 89 (34.4%) were actively bisexual. The prevalence of syphilis was 28% (74/264) and 89.2% (66/74) of these infections were asymptomatic. Multivariable logistic regression analysis showed that those patients who participated in sex with anonymous partners (OR 2.09; 95% CI, 1.03–4.26), those with a previous diagnosis of syphilis (OR 5.16; 95% CI, 1.03–25.83) and those who used marijuana in the last 12 months (OR 2.13; 95% CI, 1.14–3.96) were more likely to be diagnosed with syphilis. Conclusion There is a high prevalence of asymptomatic syphilis among MSM living with HIV in Trinidad. Repeat episodes of syphilis and anonymous sex may play a role in the transmission dynamics of T pallidum infection in this population, thus urgent public health prevention interventions are warranted.
