Congenital hydrocephalus in the northeast of Brazil: epidemiological aspects, prenatal diagnosis, and treatment

Purpose

Congenital hydrocephalus (CH) has higher proportions in developing countries such as Brazil, reaching rates of 3.16:1,000 newborns. Early diagnosis is essential and can be done during the second trimester of pregnancy, highlighting the importance of regular prenatal care. Our objective is to describe the epidemiological profile of children with CH in the state of Bahia.

Methods

Consecutive medical records of patients with CH, aged less than 2years and operated at a pediatric reference hospital between September 2009 and September 2012, were reviewed.

Results

One hundred twenty-one children underwent ventricular peritoneal shunt (VP shunt) due to CH. As for prenatal care, 38 % of pregnant women did it regularly. Males predominated with 56 % of cases with a median age of 3 months, and 68 % were from the countryside area. The most frequent clinical manifestations were bulging fontanelle (37 %) and increased head circumference (30 %). There were 13 (11 %) reports of complications associated with VP shunts. There were nine deaths (7 %), and respiratory complications were the main cause.

Conclusions

Public health measures are the key to increase mothers’ knowledge about the importance of regular prenatal monitoring. There was a predominance of male children, with a median age of 3 months, with the majority coming from the countryside.

Profile of herbal and dietary supplements induced liver injury in Latin America: A systematic review of published reports

Hepatotoxicity related to HDS is a growing global health issue. We have undertaken a systematic review of published case reports and case series from LA from 1976 to 2020 to describe the clinical features of HDS related hepatotoxicity in this region. We search in PubMed, Web of Science, Scopus and specific LA databases according to PRISMA guidelines. Only HILI cases published in LA that met criteria for DILI definition were included. Duplicate records or reports that lacked relevant data that precluded establishing causality were excluded. Finally, 17 records (23 cases) were included in this review. Centella asiatica, Carthamus tinctorius, and Herbalife® were the most reported HDS culprit products, the main reason for HDS consumption was weight loss. The clinical characteristics of HDS hepatotoxicity in our study were compared to those of other studies in the USA, Europe and China showing a similar signature with predominance of young females, hepatocellular damage, a high rate of ALF and mortality, more frequent inadvertent re‐challenge and chronic damage. This study underscores the challenge in causality assessment when multi‐ingredients HDS are taken and the need for consistent publication practice when reporting hepatotoxicity cases due to HDS, to foster HDS liver safety particularly in LA.     

Intracortical haematogenous osteomyelitis

We present an unusual case of haematogenous osteomyelitis in the diaphysis of the tibia of an adult leading to a subacute presentation with an extracortical abscess. Fluid from the abscess grew methicillin resistant Staphylococcus aureus (MRSA) on culture; MRSA with the same antibiogram had been grown from the patient’s blood seven years earlier following a bowel resection. Drainage of the abscess and curettage of the bone lesion together with appropriate antibiotic therapy led to resolution of the osteomyelitis.     

Renal Transplantation in Human Immunodeficiency Virus–Positive Patients: A Report of Four Cases

Introduction

Renal transplantation (RT) in patients infected with human immunodeficiency virus (HIV) has significantly improved under the advent of combined antiretroviral therapy (cART). The authors describe their experience in RT in patients with HIV from September 2010 to June 2013.

Cases Report

Four patients underwent transplantation (3 with HIV-1 and 1 with HIV-2), three patients were male, and one was black. None were coinfected with hepatitis B virus (HBV) or hepatitis C virus (HCV). Etiology of kidney disease was HIV-associated nephropathy (2 patients), immunoglobulin (Ig)A nephropathy, and unknown. Average age at RT was 51 (range, 41–63) years. No patient was of high immunologic risk. Immunosuppression consisted of basiliximab for induction and prednisolone, tacrolimus (TAC), and mycophenolate mofetil for maintenance. TAC levels varied considerably in the early days (8.5–46 ng/mL), requiring major adjustments in TAC dose. Only the HIV-2 patient had delayed graft function. The follow-up of patients with HIV-1 was 37, 19, and 16 months, and 3 months for the HIV-2 patient. CD4+ T cells decreased in the early days after transplantation with subsequent improvement, along with persistent virological suppression. In the HIV-1 group there were no major infectious, cardiovascular, or neoplastic complications. Nevertheless, the HIV-2 patient died 3 months after RT due to H1N1 pneumonia complicated by pulmonary aspergillosis. Average estimated (CKD- EPI) glomerular filtration rate (eGFR) at 6 months was 85.6 mL/min/1.73 m².

Conclusion

Besides the difficulty in adjusting calcineurin inhibitors levels due to its interaction with antiretroviral therapy, namely with protease inhibitors, no patient had acute rejection. Furthermore, all patients presented an excellent control of viro-immunologic parameters. At the last follow-up neither cardiovascular events nor neoplastic complications were observed. Our results highlight the favorable outcome of RT in HIV-1–infected patients. The HIV-2 patient died due to severe infection, and the clinical management and potential benefit of RT in HIV-2–infected patients needs further study.
