While the developed world is focusing on laying guidelines for selecting out cases of Asymptomatic primary hyperparathyroidism (PHPT) for surgical intervention and promoting minimal access surgery, the developing world is observing a change in disease spectrum from advanced symptomatic to lesser degree of symptomatic disease and not many with associated Vitamin D deficiency. Few studies from the developing countries of the world have focused on the changing clinical spectrum of PHPT. Objective of this study is to review the changing profile of PHPT in developing world. A systematic literature search was done in December 2017 focussing on publications from the developing world. All studies pertaining to the epidemiology of PHPT published after 1 st January 2000 and published in English language were included for analysis. Most of the studies published from developing countries report a predominance of symptomatic disease (79.6% of all included patients) with musculoskeletal disease present in the majority of patients (52.9%). The combined mean serum total calcium (11.9 ± 1.4 mg/dL), serum PTH (668.6 ± 539 pg/mL), serum alkaline phoshpatase (619 ± 826.9 IU/L) and weight of excised parathyroid glands (4.4 ± 3.8 grams) are much higher than those reported from the western studies. Despite this, we found that there is a distinct trend towards a milder form of disease presentation and biochemical profile noticeable in more recent times. Although there is a striking difference in all aspects of PHPT disease epidemiology, clinical presentation and biochemical profile of developing and developed countries, there is a distinct trend towards a milder form of disease presentation and biochemical profile in more recent times.

Introduction Major abdominal surgery is still a great contributor to postoperative morbidity and mortality in developing countries. Major abdominal surgery leads to hypoperfusion, which has an impact on postoperative morbidity and mortality. Lactate, a biomarker for hypoperfusion is under utilized in Uganda. The study aimed to investigate the association between elevated serum lactate and outcomes (in-hospital mortality, SSI and length of hospital stay) in patients following major abdominal surgery. Methods A prospective observational cohort study was done with 246 eligible patients recruited. Stratified sampling was carried out till desired sample size was achieved. Demographic and perioperative data were collected, serum lactate levels were measured at induction and immediately after surgery with serial measurements being done after 12, 24 h post operatively. Participants were followed up to assess outcomes. Data analysis was done using STATA version 14.0. Results A total of 130 patients (52.8%) had elevated serum lactate levels. Elevated serum lactate predicted in-hospital mortality and surgical site infection. The accuracy of elevated serum lactate to predict mortality with AUROC of 0.7898 was exhibited by the 24 h lactate values. Elevated serum lactate predicted surgical site infection accurately with AUROC 0.6432. Length of hospital is strongly associated with elevated serum lactate with p-value of 0.043. Patients with elevated serum lactate on average have a longer length of hospital stay at 5.34 ± 0.69. Conclusion Elevated serum lactate was associated with in-hospital mortality, surgical site infection and longer length of hospital stay. Serum lactate levels done at 24 h were most predictive of mortality and surgical site infection.

BackgroundIntestinal ischemia is a common complication of intestinal obstruction and arises from impaired perfusion. The resultant local and systemic inflammatory response and bacterial translocation come with a significant degree of morbidity and mortality. This study therefore aimed to investigate the predictive value of elevated levels of serum lactate and phosphate as biomarkers of intestinal ischemia among patients with mechanical intestinal obstruction.MethodsThis was a cross-sectional analytical study done at Mulago Hospital in Uganda. Ethical approval was obtained. All eligible patients had a blood sample drawn for assay analysis. Determination of bowel ischemia status was by physical examination at laparotomy. Analyses were performed using Stata software, version 10.1, and 2 × 2 tables were used to calculate sensitivity and specificity.ResultsSerum lactate was predictive of bowel ischemia, while phosphate was not. Of the 81 patients enrolled 70 qualified for analysis; 40/70 (57%) had ischemic bowel, while 30/70 (43%) had normal bowel. Among those with ischemic bowel, 28/40 (70%) had reversible ischemia, and 12/40 (30%) had irreversible ischemia. Serum lactate assay had a sensitivity of 66% and specificity of 53% for bowel ischemia in general and a higher sensitivity of 71% and specificity of 80% for irreversible bowel ischemia.Lactate was predictive of bowel ischemia in general (p = 0.011), PPV = 14%, but more significantly predictive of irreversible ischemia (p = 0.009), PPV = 42%. NPV for lactate in both forms of ischemia was 93%. Hernias (33/70, 47%) were the most common cause of intestinal obstruction.ConclusionSerum lactate assay had moderate sensitivity for bowel ischemia due to acute mechanical intestinal obstruction. The assay can be used to aid diagnosis of bowel ischemia in low technology settings.

In this study, we investigated the barriers to the delivery of internationally accepted breast cancer care in low resource settings (LRS) as compared to well-endowed resource settings (WRS) via an online survey. The survey was completed by 199 surgeons from eleven countries: 51 from WRS and 148 from LRS, based on our definition. The two most common facilities lacking in LRS were sentinel lymph node biopsy and immune-histochemistry (67% and 60% respectively). Only 22% respondents from LRS confirmed that all their eligible patients received hormonal therapy and only 8% radiotherapy as compared to 98% and 75% from WRS. Widespread limitations exist in most LRS, making internationally accepted breast cancer treatment guidelines impossible to follow, and thus resulting in suboptimal cancer care.

Whilst the thyroidectomy outcomes are not equal to international standards, an acceptable standard is achievable in this resource-limited setting. Poor outcomes are multifactorial but extremes of thyroid size, extremes of operation duration and total thyroidectomies all have statistically poorer outcomes in this setting.
