Abstract
PURPOSE Acquired rectovaginal fistulae (RVF) are a complication of paediatric HIV infection. We report our experience with the surgical management of this condition. METHODS We retrospectively reviewed the records of paediatric patients with HIV-associated RVF managed at Chris Hani Baragwanath Academic Hospital (2011-2023). Information about HIV management, surgical history, and long-term outcomes was collected. RESULTS Ten patients with HIV-associated RVF were identified. Median age of presentation was 2 years (IQR: 1-3 years). Nine patients (9/10) underwent diverting colostomy, while one demised before the stoma was fashioned. Fistula repair was performed a median of 17 months (IQR: 7.5-55 months) after colostomy. An ischiorectal fat pad was interposed in 5/9 patients. Four (4/9) patients had fistula recurrence, 2/9 patients developed anal stenosis, and 3/9 perineal sepsis. Stoma reversal was performed a median of 16 months (IQR: 3-25 months) after repair. Seven patients (7/9) have good outcomes without soiling, while 2/9 have long-term stomas. Failure to maintain viral suppression after repair was significantly associated with fistula recurrence and complications (φ = 0.8, p < 0.05). CONCLUSION While HIV-associated RVFs remain a challenging condition, successful surgical treatment is possible. Viral suppression is a necessary condition for good outcomes.

Abstract
According to the joint United Nations Programme on HIV/AIDS (UNAIDS), 37.7 million adults and children worldwide were estimated to be living with HIV or acquired immune deficiency syndrome (AIDS) at the end of 2020 [UNAIDS. (2022). http://www.unaids.org . Accessed 30 May 2022]. Most reside in low- and middle-income countries, with approximately 67% in sub-Saharan Africa (SSA). At the end of 2020, the total number of children less than 15 years of age living with HIV infection was 2.6 million, of whom 2.3 million (88%) were living in SSA. Aggressive interventions have reduced the annual number of incident (new) HIV infections among children to around 150,000 [UNAIDS. (2022). http://www.unaids.org . Accessed 30 May 2022]. However, paediatric HIV infection remains a pandemic affecting children predominantly in SSA but is also seen in Asia and sporadically elsewhere particularly in areas of civil strife such as is currently the case in Ukraine [War in Ukraine. (2022). https://www.unaids.org/en/War-Ukraine-special . Accessed Apr 2022]. New HIV infections among children declined by more than half (54%) from 2010 to 2020, due mainly to the increased provision of antiretroviral therapy to pregnant and breastfeeding women living with HIV [UNAIDS. (2022). http://www.unaids.org . Accessed 30 May 2022]. These programmes include early identification of HIV infection in pregnant or breastfeeding women through routine HIV testing, provision of antiretroviral therapy (ART) to all HIV-infected women who are pregnant or breastfeeding, provision of antiretroviral prophylaxis to their newborn infants during the first 6-12 weeks of life, delivery by elective Caesarean section when indicated, promotion of exclusive breastfeeding, early infancy screening for HIV infection, and initiation of ART in infants with HIV infection. HIV-infected children may require surgery either as an emergency to deal with a life-threatening incidental condition unrelated to HIV infection or for a complication of the disease such as tuberculosis or an aggressive soft tissue infection like necrotising fasciitis. Non-emergency surgical procedures may be required to assist in the diagnosis of an HIV-related condition or to correct a routine surgical problem electively. Surgical conditions associated with HIV infection are described under categories of soft tissue or organ-specific infections requiring drainage or debridement; gastrointestinal tract disease and complications; infections in the perineal area; malignancies and HIV-associated vasculitis. Although surgical outcomes are less favourable in HIV-infected children, pre-operative treatment of coinfections, administration of cotrimoxazole prophylaxis, nutritional support and antiretroviral therapy, together with peri-operative antibiotic prophylaxis have resulted in excellent short-term outcomes [World Health Organization. Consolidated guidelines on the use of antiretroviral drugs for treating and preventing HIV infection: Recommendations for a public health approach, June 201 http://www.apps.who.int/iris/bitstream/10665/85321/1/9789241505727_eng.pdf?ua=1 ; World Health Organization Guideline on when to start antiretroviral therapy and on pre-exposure prophylaxis for HIV, September 2015. http://www.apps.who.int/iris/bitstream/10665/186275/1/9789241509565_eng.pdf?ua=1;Eley et al. in BMC Infect Dis 2:3, 2002;Karpelowsky et al. in Pediatr Surg Int 28:1007-1014, 2012;].

Abstract
BACKGROUND/PURPOSE To assess the number of patients seen at the colorectal clinic of a low-to-middle income-country with emphasis on their social circumstances. METHODS Between January 2013 and December 2018 we recorded the number of visits to colorectal clinic. From February 2019 prospective data on patients with anorectal malformations (ARMs) focusing on their social conditions (type of housing and sanitation) and HIV-exposure were collected. RESULTS At the clinic 452 visits were recorded in 2013, 608 in 2014, 904 in 2016, 1392 in 2017, and 1968 in 2018. The ARM cohort included 100 patients: at the time of delivery the HIV status of 74 mothers was negative, positive in 21, and unknown in 5. None of the HIV-exposed patients seroconverted to HIV positive (average follow-up:39 months). Seventy-four patients live in formal settlements, 23 in informal, and 3 in unknown type. Forty-six patients have inside toilets, 39 outside flushing toilets, 10 outside pit latrines, 2 community toilets, and 3 an unknown sanitation. CONCLUSIONS The clinic work-load has increased during the past years. A significant proportion of our patients are HIV-exposed, do not live in formal houses and do not have inside toilets. Tailored strategies for a successful surgical plan and bowel management need to be implemented. LEVEL OF EVIDENCE II.

Abstract
BACKGROUND HIV has become a chronic disease, which may render this population more prone to developing the colorectal pathologies that typically affect older Americans. METHODS A retrospective review of the Nationwide Inpatient Sample was performed to identify patients who underwent colon and rectal surgery from 2001 to 2010. Multivariate analysis was used to evaluate outcomes among the general population, patients with HIV, and patients with AIDS. RESULTS Hospital admissions for colon and rectal procedures of patients with HIV/AIDS grew at a faster rate than all-cause admissions of patients with HIV/AIDS, with mean yearly increases of 17.8 and 2.1 %, respectively (p < 0.05). Patients with HIV/AIDS undergoing colon and rectal operations for cancer, polyps, diverticular disease, and Clostridium difficile were younger than the general population (51 vs. 65 years; p < 0.01). AIDS was independently associated with increased odds of mortality (OR 2.11; 95 % CI 1.24, 3.61), wound complications (OR 1.53; 95 % CI 1.09, 2.17), and pneumonia (OR 2.02; 95 % CI 1.33, 3.08). Risk-adjusted outcomes of colorectal surgery in patients with HIV did not differ significantly from the general population. CONCLUSION Postoperative outcomes in patients with HIV are similar to the general population, while patients with AIDS have a higher risk of mortality and certain complications.

Abstract
BACKGROUND Patients with HIV/AIDS on antiretroviral therapy (ART) live longer and now require surgery for indications similar to those described for the general population. They have been previously reported to carry higher mortality and complication rates, especially septic complications. The aim of this study was to compare the outcome of major abdominal surgery in three groups of patients with different CD4 counts. METHODS This is a prospective study comparing HIV-negative patients and two groups of HIV-infected patients on ART with different CD4 counts. The primary outcomes considered were mortality and complication rates after abdominal surgery. We emphasised on the value of CD4 as a predictor of outcome and the impact of the indication for surgery (septic versus non-septic). RESULTS We included 63 patients (21 per group). The majority of patients (71 %) were operated on as an emergency and the indications were similar in all groups. The overall and the septic complication rates were both higher in the group with a low CD4 count. This resulted in a significantly longer admission period but did not result in a higher mortality rate. The duration of ART and the World Health Organisation stage of the disease did not significantly influence surgical outcomes. CONCLUSIONS HIV-infected patients on ART can now safely undergo major abdominal surgery with encouraging results though still relatively poorer than those of HIV-negative subjects. CD4 count remains a significant predictor of outcome and patients with a low CD4 count, however, still require closer pre- and post-operative monitoring.

Abstract
Renal transplantation is being performed in adult human immunodeficiency virus (HIV)-positive patients and increasingly in paediatric patients as well. A multidisciplinary team involving an infectious disease professional is required to assist with HIV viral-load monitoring and in choosing the most appropriate highly active antiretroviral therapy (HAART). Drug interactions complicate immunosuppressant therapy and require careful management. The acute rejection rates appear to be similar in adults to those in noninfective transplant recipients. Induction with basiliximab and calcineurin-based immunosuppression appears to be safe and effective in these recipients. Prophylaxis is advised for a variety of infections and may need life-long administration, especially in children. Organ shortage remains a significant problem, and kidneys from deceased HIV-positive donors have been used successfully in a small study population. Overall, with careful planning and close follow-up, successful renal transplantation for paediatric HIV-infected recipients is possible.

Abstract
Burn injuries in Africa are common with between 300,000 and 17.5 million children under 5 years sustaining burn injuries annually, resulting in a high estimated fatality rate. These burns are largely environmentally conditioned and therefore preventable. The Western Cape Province in South Africa can be regarded as a prototype of paediatric burns seen on the continent, with large numbers, high morbidity and mortality rates and an area inclusive of all factors contributing to this extraordinary burden of injury. Most of the mechanisms to prevent burns are not easily modified due to the restraint of low socio-economic homes, overcrowding, unsafe appliances, multiple and complex daily demands on families and multiple psycho-social stressors. Children <4 years are at highest risk of burns with an average annual rate of 6.0/10,000 child-years. Burn care in South Africa is predominantly emergency driven and variable in terms of organization, clinical management, facilities and staffing. Various treatment strategies were introduced. The management of HIV positive children poses a problem, as well as the conflict of achieving equity of burn care for all children. Without alleviating poverty, developing minimum standards for housing, burn education, safe appliances and legislation, we will not be able to reduce the "curse of poor people" and will continue to treat the consequences.

Abstract
PURPOSE OF REVIEW The introduction of combination ART to prevent mother-to-child-transmission (MTCT) has substantially decreased MTCT rates. However, there are concerns regarding safety of ART exposure for the mother, pregnancy outcome and infant. Changing MTCT prevention guidelines, with expanded eligibility, have led to a rapid increase of ART-treated women and exposed infants in high prevalence regions. RECENT FINDINGS Recent studies confirm that ART in HIV-infected mothers decreases disease progression and mortality, also after delivery. However extended duration of ART, especially HAART, during pregnancy has also been associated with premature delivery, small-for-gestational age (SGA) infants and pregnancy complications including hypertension. In the uninfected infant, ART exposure was associated with levels of hematologic and immunological markers, which, in high microbial regions, may be clinically relevant, especially in combination with premature birth and SGA. Altered mitochondrial functioning is reported in ART-exposed children although clinical implications remain difficult to discern. SUMMARY The benefit of ART in the prevention of MTCT is beyond doubt, but there are reports on adverse effects on pregnancy outcome and infant currently also from high prevalence regions. Further research regarding safety is urgently required, as the number of pregnant women on ART and exposed uninfected infants is rapidly increasing.

Abstract
PURPOSE Increasingly HIV-infected children can be expected to require surgery. The aim of this study was to compare the outcome of HIV-infected and HIV-unexposed children undergoing surgery. PATIENTS AND METHODS A prospective study of children less than or equal to 60 months admitted to a tertiary pediatric surgical service from July 2004 to July 2008. Children underwent age-definitive HIV testing and were followed up postoperatively for complications, length of stay and mortality. RESULTS Three hundred and twenty-seven children were enrolled: 82 (23 %) HIV-infected and 245 (67 %) were HIV-unexposed. Eighty-four (26 %) children were malnourished, which was higher in the HIV-infected group [41 (50.0 %) vs. 43 (17.5 %), relative risk (RR) 2.9; 95 % confidence interval (CI) 2.0-4.1; p < 0.0001]. Three hundred and twenty-eight surgical procedures were performed. A similar number of major [28 (34.2 %) vs. 64 (26.1 %); p = 0.2] and emergency procedures [37 (45.1 %) vs. 95 (38.8 %); p = 0.34] were performed in each group. HIV-infected children had a higher rate of contamination at surgery [40 (48.7 %) vs. 49 (20 %); RR 2.43 (CI 1.7-3.4); p < 0.0001]. There were more complications in the HIV-infected group [34 (41.5 %) vs. 14 (5.7 %); RR 7.3 (CI 4.1-12.8); p < 0.0001]. The most common complications were surgical site complications 30 (55 %), followed by postoperative infections, 19 (34 %). Infections with drug-resistant organisms occurred more commonly in HIV-infected children [11/19 (58 %) vs. 2/13 (15 %); RR 3.8 (CI 1.3-14.2); p = 0.02]. The median length of hospital stay was longer in the HIV-infected group [4 (IQR 2-14) vs. 2 (IQR 1-4) days; p = 0.0001]. There was a higher mortality amongst the HIV-infected group [6 (7.3 %) vs. 0 (0 %); p < 0.0001]. CONCLUSION HIV-infected children have a higher rate of postoperative complications and mortality compared with HIV-unexposed children.

Abstract
Infections and their complications requiring surgical intervention are a frequent presentation in African children. Surgical site infection (SSI) is common with rates over 20%, even after clean procedures. The high rates of SSI are due in part to lack of infection control and surveillance policies in most hospitals in Africa. SSI is attended by complications, long hospital stay, and some mortality, but the economic consequences are unestimated. Typhoid fever and typhoid intestinal perforation are major problems with perforation rates of approximately 10%, which is higher in older children. The ideal surgical treatment is arguable, but simple closure and segmental resection are the present effective surgical options. Because of delayed presentation, complications after surgical treatment are high with a mortality approaching 41% in some parts of Africa. Nutrition for these patients remains a challenge. Acute appendicitis, although not as common in African children, often presents rather late with up to 50% of children presenting with perforation and other complications, and mortality is approximately 4% is some settings. Pyomyositis and necrotizing fasciitis are the more common serious soft-tissue infections, but early recognition and prompt treatment should minimize the occasional mortality. Though common in Africa, the exact impact of human immunodeficiency virus infection on the spectrum and severity of surgical infection in African children is not clear, but it may well worsen the course of infection in these patients.

Abstract
Pediatric HIV (human immunodeficiency virus) is a pandemic predominantly in sub-Saharan Africa. Approximately 2.2 million children aged less than 15 years are infected with HIV, representing almost 95% of the total number of children globally infected with HIV. Therefore, increasing numbers of HIVi or -exposed but uninfected children can be expected to require a surgical procedure to assist in the diagnosis of an HIV/acquired immune deficiency syndrome-related complication, to address a life-threatening complication of the disease, or for routine surgery encountered in HIV-unexposed children. HIVi children may present with both conditions unique to HIV infection and surgical conditions routine in pediatric surgical practice. HIV exposure confers an increased risk of complications and mortality for all children after surgery, whether they are HIV infected or not. This risk of complications is higher in the HIVi group of patients. These findings seem to be independent of whether patients undergo an elective or emergency procedure, but the risk of an adverse outcome is higher for a major procedure. Surgical implications of HIV infection are comprehensively reviewed in this article.

Abstract
Umbilical hernias occur frequently in children but complications are very rare and thus surgery is not routinely indicated. In this literature review, we report 19 cases of spontaneous evisceration of abdominal contents through umbilical hernias. Precipitating causes included umbilical ulceration or sepsis, crying, respiratory infection, intussusception and ascites. Management involved resuscitation and surgical repair. Mortality is low. As the incidence of spontaneous rupture is very low, the current management of an umbilical hernia remains appropriate. However, we encourage physicians to be aware of the potential risk factors for spontaneous rupture and in these patients expedite surgical repair.

Abstract
BACKGROUND/PURPOSE The heavy burden of maternal HIV infection in developing countries such as South Africa has resulted in a high prevalence of premature birth and necrotizing enterocolitis (NEC). Uninfected infants born to HIV-infected mothers also demonstrate immune deficiencies. It is, therefore, essential to have a better understanding of how to mitigate HIV as an independent risk factor for surgically treated NEC and to evaluate the relevant contributing factors in the presence of an aggressive strategy of pasteurized breast milk feeding and antiretroviral prophylaxis. METHODS Infants with stage IIIb NEC presenting over a 4-year period were retrospectively reviewed. HIV-exposed infants were compared with non-HIV-exposed infants. Contributing factors were evaluated and studied by systematic statistical methods to evaluate risk. RESULTS Twenty percent (17/87) infants were HIV-exposed, and 80% (70/87), unexposed, whereas a further 10 (total, n = 97) had unknown HIV exposure status. Demographics and other perinatal risk factors between the 2 groups were not significantly different other than that HIV-exposed infants received pasteurized breast milk and nonexposed infants received unpasteurized breast milk. There were no statistically significant differences between the groups with respect to disease presentation or severity, surgical findings or type of surgery, postoperative complications, survival, or timing of death. Trends toward higher antenatal steroid exposure and increased postoperative sepsis in the HIV-exposed group (P = .03) were noted but were not related. All HIV-exposed infants received antiretrovirals; there were no significant differences on subanalysis between different antiretroviral regimens. CONCLUSIONS HIV-exposed infants do not have a more severe disease course nor more adverse outcomes in stage IIIb NEC than unexposed infants. Significant factors were antenatal steroids and post-NEC infective episodes.

Abstract
BACKGROUND An increasing number of HIV-infected children require a surgical procedure. The aim of this study was to investigate factors associated with the development of complications in HIV-infected children undergoing surgery. METHODS A prospective study of HIV-infected children younger than 60 months undergoing surgery at a tertiary referral pediatric hospital from July 2004 to July 2008 was performed. Children were followed postoperatively for the development of complications, length of stay, and mortality. RESULTS Eighty-two HIV-infected children, with a median age of 11.5 months (interquartile range, 6-24 months), were enrolled. Most (68; 82.9%) had World Health Organization stage 3 or 4 HIV disease, 72 (88%) had Centers for Disease Control and Prevention stage 2 or 3 disease, and 60 (73%) were taking highly active antiretroviral therapy. Half (41; 50%) were underweight, 37 (45.1%) underwent emergency surgery, 28 (34.2%) required major surgery, and 40 (48.7%) had surgical site contamination at the time of surgery. The median length of hospital stay was 4 days (interquartile range, 2-14 days), and in-hospital mortality was 6 (7%). Thirty-four (42%) children developed 37 complications. On univariate analysis, malnutrition, HIV stage, or type of surgery was not associated with development of complications. In contrast, young age (6 vs 13.5 months; P = .0004), low hemoglobin (9.6 vs 10.5 g/dL; P = .04), or having a major procedure (14 [42%] vs 9 [18%]; P = .03; relative risk, 2.2 [1.2-4.8]) was associated with complications. On logistic regression, younger age (odds ratio = 4.3; P = .004; 95% confidence interval, 1.6-11.9) and major surgery (odds ratio = 6.8; P = .001; 95% confidence interval, 1.5-31.4) were associated with development of a complication. CONCLUSION Young age and major surgery were the main predicators of complications in HIV-infected children undergoing surgery.

Long-term outcome of surgically managed necrotizing enterocolitis in a developing country. Pediatr Surg Int 2010; 26:355-60. [PMID: 20204650 DOI: 10.1007/s00383-010-2583-8] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 02/09/2010] [Indexed: 10/19/2022]
Abstract
UNLABELLED Necrotizing enterocolitis (NEC) is a serious condition with a high morbidity and mortality commonly affecting premature babies. Data for the impact of the long-term disease burden in developing countries are limited although poor long-term outcome of surgically managed patients has been shown in terms of increased risk of neurodevelopmental delay, increased infectious disease burden and abnormal neurological outcomes in the developed world. PURPOSE To evaluate the long-term outcome of a pre-human immunodeficiency virus pandemic NEC cohort to characterize common risk factors and outcome in a developing world setting. METHODS A retrospective review of medical records was carried out on a cohort of 128 premature neonates with surgical NEC (1992-1995). Morbidity, mortality and long-term outcome were evaluated. RESULTS Data for 119 of 128 sequentially managed neonates with surgically treated NEC was available. Mean gestational age was 32 weeks and average birth weight was 1,413 g. Early (30-day postoperative) survival was 69% (n = 82) overall and 71% in the <1,500 g birth weight group (n = 68; 53%). Overwhelming sepsis (n = 16) or pan-intestinal necrosis (n = 18) accounted for most of the early deaths. Late deaths (>30 days postoperatively, n = 22) resulted from short bowel syndrome (5), sepsis (9), intraventricular hemorrhage (1) and undetermined causes (7). On follow-up (mean follow-up 39 months, 30 for >2 years), long-term mortality increased to 50%. Late surgical complications included late colonic strictures (9), incisional hernias (2) and adhesive bowel obstruction (3). Fifteen patients had short bowel syndrome, of which 10 (66%) survived. Of the long-term survivors, 8 (20%) had severe neurological deficits and 20 (49%) had significant neurodevelopmental delay. Neurological deficits included severe auditory impairment [5 (12%)] and visual impairment [4 (10%)]. Recurrent infections and gastrointestinal tract complaints requiring hospital admission occurred in 16 (39%) of survivors. CONCLUSION Necrotizing enterocolitis in premature infants impacts morbidity and mortality considerably. A number do well in a developing country, but septic complications may be ongoing and recurrent. The high risk of neurodevelopmental and other problems continue beyond the neonatal period and patients should be "flagged" on for careful follow-up.
