RESUMO
Objective: To assess the outcomes of a contact-tracing programme to increase the diagnosis of tuberculosis in Cubal, Angola and offer preventive treatment to high-risk groups. Methods: A health centre-based contact-tracing programme was launched in Hospital Nossa Senhora da Paz in March 2015 and we followed the programme until 2022. In that time, staffing and testing varied which we categorized as four periods: medical staff reinforcement, 2015-2017, with a doctor seconded from Vall d'Hebron University Hospital, Spain; routine staff, 2017-2021, with no external medical support; community directly observed treatment (DOT), 2018-2019 with community worker support; and enhanced contact tracing, 2021-2022, with funding that allowed free chest radiographs, molecular and gastric aspirate testing. We assessed differences in contacts seen each month, and testing and treatment offered across the four periods. Findings: Overall, the programme evaluated 1978 contacts from 969 index cases. Participation in the programme was low, although it increased significantly during the community DOT period. Only 16.6% (329/1978) of contacts had a chest radiograph. Microbiological confirmation increased to 72.2% (26/36) after including molecular testing, and 10.1% (200/1978) of contacts received treatment for tuberculosis. Of 457 contacts younger than 5 years, 36 (7.9%) received preventive tuberculosis treatment. Half of the contacts were lost to follow-up before a final decision was taken on treatment. Conclusion: Contact tracing increased the diagnosis of tuberculosis although engagement with the programme was low and loss to follow-up was high. Participation increased during community DOT. Community-based screening should be explored to improve participation and diagnosis.

INTRODUCTION: The objective of this study was to describe the main characteristics of migrants diagnosed with human T-lymphotropic virus (HTLV) infection within the +Redivi Spanish network. METHODS: Patients with a diagnosis of HTLV type 1 or 2 in +Redivi from October 2009 to December 2020 were included. Diagnosis was based on positive HTLV serology (enzyme-linked immunosorbent assay (ELISA)/chemiluminescent immunoassay (CLIA)) with line immunoassay (LIA)/Western blot with/without polymerase chain reaction (PCR). RESULTS: A total of 107/17 007 cases (0.6%) had a final diagnosis of HTLV infection: 83 (77.67%) HTLV-1 infections, 6 (5.6%) HTLV-2 infections and 18 (16.8%) non-specified. The majority (76, 71%) were female, median age was 42 years and median time from arrival to Spain until consultation was 10 years. The group included 100 (93.5%) immigrants and 7 (6.6%) visiting friends and relatives (VFR)-immigrants. Most patients were from South America (71, 66.4%), followed by Sub-Saharan Africa (15, 14%) and Central America-Caribbean (13, 12.1%). Around 90% of patients were asymptomatic at presentation and diagnosed as part of screening programs. Median duration of follow-up was 5 years (IQR 2-7). Regarding HTLV-associated conditions, 90 patients (84.2%) had none, 7 (6.5%) had tropical spastic paraparesis , 5 (4.7%) had other associated conditions (dermatitis, uveitis, pulmonary disease), 3 (2.8%) had other neurological symptoms and 2 (1.9%) had adult T-cell leukaemia/lymphoma. No patients with HTLV-2 had HTLV-associated conditions. Four patients (3.7%) died. Concomitant diagnoses were found in 41 (38.3%) patients, including strongyloidiasis in 15 (14%) and HIV co-infection in 4 (3.7%). In 70% of patients, screening of potential contacts was not performed/recorded. CONCLUSIONS: HTLV infections (the majority due to HTLV-1) were mainly diagnosed in asymptomatic migrants from Latin America (generally long-settled immigrants and the majority female with the consequent implications for screening/prevention). A high rate of association with strongyloidiasis was found. In the majority, screening of potential contacts was not performed, representing a missed opportunity for decreasing the under diagnosis of this infection.

BACKGROUND: Treatment guidelines suggest either a low-dose or high-dose approach when prescribing amikacin for nontuberculous mycobacterial pulmonary disease (NTM PD), but data supporting the low-dose approach are limited. The purpose of this study was to describe the safety and efficacy of the use of a low-dose of intravenous amikacin in a cohort of patients with NTM PD. METHODS: We retrospectively reviewed all patients with NTM PD who received amikacin at our institution between July 1, 2003 and February 28, 2017. Demographics, clinical, microbiological and radiological data, indication and dose of amikacin, and adverse drug effects were recorded. RESULTS: A total of 107 patients received a regimen containing amikacin for a median (IQR) of 7 (4-11) months. Seventy (65.4%) were female and the mean age (SD) was 58.3 (14.9) years. Amikacin was started at a median dose of 9.9 (2.5) mg/kg/day. Ototoxicity was observed in 30/77 (39%) patients and it was related to female sex (OR 4.96, 95%CI 1.24-19.87), and total dose of amikacin per bodyweight (OR 1.62, 95%CI 1.08-2.43). Patients of East Asian ethnicity were less likely to develop ototoxicity (0.24, 95%CI 0.06-0.95). Out of 96 patients who received amikacin for more than 3 months, 65 (67.7%) experienced symptom improvement and 30/62 (49.2%) converted their sputum to culture negative within a year. CONCLUSIONS: Patients with NTM PD treated with low-dose intravenous amikacin frequently developed ototoxicity, which was associated with female sex, and total dose of amikacin per bodyweight. Physicians should carefully consider dose, treatment duration, and long term prognosis in balancing risks and benefits of intravenous amikacin in NTM PD.

BACKGROUND AND OBJECTIVES: Lung resection in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD) is considered when medical therapy alone fails to provide long term control. Data regarding comparative and long-term outcomes are limited. We aimed to review indications and outcomes of adjuvant lung resection for NTM-PD compared with controls. METHODS: We retrospectively studied 27 surgically treated patients, matched 1:1 for age, sex, NTM species, and radiologic pattern of disease, with control patients treated exclusively with antibiotics. RESULTS: In the surgical group, the median (IQR) age was 55 (49-61) years and 74.1% were female. Eighteen patients had Mycobacterium avium complex, and 9 had M. xenopi. Operations included 8 pneumonectomies, 20 lobectomies, one segmentectomy and one lobectomy plus segmentectomy. Post-surgical complications occurred in 6 patients (20%), including 2 acute respiratory distress syndrome, 1 bronchopleural fistula, 1 pericardial tamponade, and 2 empyema. Complications were more common among patients operated upon for progressive disease despite medical therapy (OR 10, pâ¯=â¯0.025). Of 24 matched pairs followed for ≥1 year, sustained culture conversion was observed in 21 (87.5%) patients in the surgical group and in 11 (45.8%) patients in the non-surgical group (RR 2.36, 95%CI 1.37-4.03, pâ¯=â¯0.002). Median (IQR) percentage of follow-up time on antibiotics was 14% (0-100%) in the surgical group and 83% (10.8%-100%) in the non-surgical group (pâ¯=â¯0.195) during a median (IQR) follow-up of 16 (2-36) months. CONCLUSIONS: NTM-PD patients who underwent adjuvant lung resection experienced significant morbidity and more frequently achieved sputum culture conversion. Long term antibiotic requirements may have been reduced.

Urinary schistosomiasis causes damage to the urological system. Ultrasound is a method that detects the burden of secondary disease, individually and in epidemiological studies. In this study, the Schistosoma haematobium-associated urinary tract pathology is analyzed before and after treatment in a short period of time. Seventy children who had previously participated in an epidemiological study on schistosomiasis in the city of Cubal, Angola, and had also performed urinary ultrasound between August 2013 and February 2014 were cited 6-8 months later to assess the possible reinfection and repeat new urinary ultrasound, analyzing changes at the level of urinary pathology. The presence of hematuria and proteinuria was also analyzed. Of the 70 children analyzed, 29 (41.4%) were girls, with an average age of 10.4 years (standard deviation 2.3). Fifty-three (75.7%) had an improvement in their bladder and/or kidney scores, whereas 12 (17.1%) had no change and five (7.1%) had progression of the disease. None of the parameters analyzed completely disappeared. After one single course of treatment with praziquantel, all the analyzed parameters showed regression. Improvement was greater in the urinary bladder than in the upper urinary tract, though these lesions also reversed; the reversion of all parameters was greater among children older than 10 years old than the younger ones. Proteinuria was the parameter with a smaller reduction. Ultrasound should be a usual tool for diagnosis and follow-up in urinary schistosomiasis, particularly in children; more accurate recommendations about follow-up in the case of children whose lesions do not reverse should be established.

BACKGROUND: The purpose of this study was to determine whether administration of postoperative antibiotics affects the incidence of complications after primary cleft palate repair in a developing area. METHODS: This study was a prospective, double-blind, randomized, placebo-controlled trial composed of 518 consecutive patients who underwent primary cleft palate repair at a single institution. Patients were aged 1 to 43 years at the time of surgery (median, 9 years). The patients were divided randomly into two groups. One group received a 5-day regimen of oral amoxicillin (50 mg/kg/day) postoperatively and the other group received placebo medication. Both groups received a single dose of cefuroxime (30 mg/kg) before incision. Patients and providers were blinded to the randomization. Patients were followed postoperatively for early complications (infection and wound breakdown) and for late complications (palatal fistulas). RESULTS: The incidence of early complications was 13.8 percent among the patients in the placebo group and 8.7 percent among the patients in the antibiotic group (p = 0.175). Fistulas were noted in 17.1 percent in the placebo group and in 10.7 percent in the antibiotic group (p = 0.085). Logistic regression analysis identified visiting surgeons as the only covariate related to early complications (OR, 3.71; p < 0.001). However, the use of placebo (OR, 2.09; p = 0.037), female sex (OR, 2.04; p = 0.047), and Veau III and IV (OR, 3.31; p = 0.004) were observed as factors associated with the incidence of fistulas. CONCLUSION: The authors' results indicate that postoperative antibiotic prophylaxis can reduce the incidence of fistulas after primary cleft palate repair in a developing area.

BACKGROUND: Some surgical pathologies eventually require intestinal resection. This may lead to an extended procedure such as leaving 30 cm of proximal jejunum and left and sigmoid colon. One of the most important consequences of this type of resection is [quot ]intestinal failure[quot ] or short bowel syndrome. This complex syndrome leads to different metabolic and water and acid/base imbalances, as well as nutritional and immunological challenges along with the problem accompanying an abdomen subjected to many surgical procedures and high mortality. Many surgical techniques have been developed to improve quality of life of patients. METHODS: We designed a non-transplant surgical approach and performed the procedure on two patients with postoperative short bowel syndrome with <40 cm of proximal jejunum and left colon. RESULTS: There are a variety of non-transplant surgical procedures that, due to their complex technique or high mortality rate, have not resolved this important problem. However, the technique we present in this work can be performed by a large number of surgeons. The procedure has a low morbimortality rate and offers the opportunity for better control of metabolic and acid/base balance, intestinal transit and proper nutrition. CONCLUSIONS: We consider that this technique offers a new alternative for the complex management required by patients with short bowel syndrome and facilitates their long-term nutritional control.
