Comparative study of laparoscopic and open surgery in management of 50 cases of liver hydatid cyst

Background: Echinococcosis is caused by parasite called Echinococcus granulosus and Echinococcus multilocularis. The modern treatment of hydatid cyst of the liver varies from surgical intervention to percutaneous drainage or medical therapy.Methods: This clinical study was done on 50 patients who had liver hydatid disease admitted in Sir T Hospital, Bhavnagar from August 2013 to February 2016. Patients were divided into two groups consisting of 25 cases in each. Group A: managed by open surgery. Group B: managed by laparoscopic surgery. All patients followed up for 6 months after surgery.Results: The mean operative time in Group A was 65.2 minutes (range 35-100 minutes) while in Group B it was 76.32 minutes (range 50-100 minutes). Group B patients were mobilised early and resumed duty very fast then Group A. The mean duration of stay in hospital was 12.4 days (range 4-20 days) in Group A and  6.2 days (range 4-12 days) in Group B. Wound infection seen in 16% in Group A and 0% in Group B. General complication rate was 32% in Group A and 8% in Group B. No recurrence noticed in either group during follow up.Conclusions: Overall laparoscopic management of liver hydatid cyst is cost effective in terms of early mobilization, early discharge and early resumption of work along with cosmetic benefit.

Diabetes mellitus and COVID-19: A review and management guidance for South Africa

This article reviews the association between diabetes mellitus (DM) and COVID-19. We report on the convergence of infectious diseases such as coronavirus infections and non-communicable diseases including DM. The mechanisms for the interaction between COVID-19 and DM are explored, and suggestions for the management of DM in patients with COVID-19 in South Africa are offered

Blood pressure measurement in obese patients: non-invasive proximal forearm versus direct intra-arterial measurements

Background: In obesity, accurate perioperative blood pressure measurement using upper arm, non-invasive blood pressure (NIBP) is technically challenging. Proximal forearm NIBP may be an acceptable substitute. Mean arterial blood pressures (MAP) estimated by proximal forearm NIBP were compared with direct intra-arterial measurements. It was hypothesised that the measurement techniques would be interchangeable if between-technique MAP differed ≤ 20% and MAP ratios were < 1.2 and > 0.8. Method: A total of 30 adults with body mass index ≥ 30 kg/m2 in whom perioperative intra-arterial blood pressure measurement was considered mandatory were enrolled. MAP measurements using the two techniques were obtained at three random intervals in each patient. Bland­Altman analyses were employed. Results: Forearm mean NIBP MAP overestimated mean intra-arterial MAP by 2.2 (SD 8.1; range from 23.8 to ­19.4 mmHg; p = 0.011, 95% CI 3.9 to 0.5). However, Bland­Altman analyses revealed a wide dispersion with several MAP differences and MAP ratios exceeding the pre-specified bounds for interchangeability. Conclusion: Forearm NIBP could not be considered interchangeable with direct intra-arterial MAP measurements in obese patients

Preoperative fasting times: Prescribed and actual fasting times at Universitas Hospital Annex, Bloemfontein, South Africa

Background. Guidelines recommend a preoperative fasting period of 6 hours for solid food and 2 hours for clear fluids. Because of fixed meal times and imprecise operation starting times, patients often fast for an extended period of time.Objective. To investigate the prescribed preoperative fasting times, and the actual duration of fasting, compared with the internationally accepted fasting times for solid food and clear fluids.Methods. Patients (N=105) aged 14 - 60 years, who were scheduled for elective surgery in the morning session (list starting time 07h00), were included in this prospective study. On arrival in theatre, all patients were asked when they last ate and drank. Anaesthetic records were used to determine the prescribed fasting times and operation starting times. Results. For solids, patients were most frequently prescribed to start fasting from 22h00 to 00h00 (53.3% and 39.1%, respectively). No patient fasted <8 hours. The median duration of fasting was 14 hours and 45 minutes (range 9 hours and 45 minutes - 19 hours and 5 minutes). For fluids, patients were most frequently prescribed to start fasting from 05h00 (46.7%), 00h00 (27.6%) and 22h00 (7.6%). In practice, no patient ingested fluids after 22h30 or <9 hours preoperatively. The median fasting time for oral fluids was 13 hours and 25 minutes (range 9 hours and 37 minutes - 19 hours and 5 minutes).Conclusion. Most patients started fasting too early preoperatively, consequently withholding food and oral fluids for longer than recommended. An increased awareness regarding complications of unnecessarily long fasting times, and interventions to correct this problem, is required

Cerebral malaria [letter]

When young children are infected with P. falciparum; meningitis is often incidentally associated with parasitaemia and can be difficult to distinguish clinically from cerebral malaria. There is yet no clear evidence that lumbar puncture is dangerous in cerebral malaria and it is reasonable to do lumbar punctures to exclude bacterial meningitis in children with fever and coma in areas where malaria is endemic
