Risk factors of congenital hydrocephalus: a case-control study in a lower-middle-income country (Egypt).

OBJECTIVE: Hydrocephalus is the most common brain disorder in children and is more common in low- and middle-income countries. Research output on hydrocephalus remains sparse and of lower quality in low- and middle-income countries compared with high-income countries. Most studies addressing hydrocephalus epidemiology are retrospective registry studies entailing their inherent limitations and biases. This study aimed to investigate child-related, parental, and socioeconomic risk factors of congenital hydrocephalus (CH) in a lower-middle-income country. METHODS: An investigator-administered questionnaire was used to query parents of patients with CH and controls who visited the authors' institution from 2017 until 2021. Patients with secondary hydrocephalus and children older than 2 years of age at diagnosis were excluded. Uni- and multivariable logistic regression was performed to identify the factors affecting CH development. RESULTS: Seven hundred forty-one respondents (312 cases and 429 controls) were included in this study. The authors showed that maternal diseases during pregnancy (OR 3.12, 95% CI 1.96-5.03), a lack of periconceptional folic acid intake (OR 1.92, 95% CI 1.32-2.81), being a housewife (OR 2.66, 95% CI 1.51-4.87), paternal illiteracy (OR 1.65, 95% CI 1.02-2.69), parental consanguinity (OR 3.67, 95% CI 2.40-5.69), a history of other CNS conditions in the family (OR 2.93, 95% CI 1.24-7.34), conceiving a child via assisted fertilization techniques (OR 3.93, 95% CI 1.57-10.52), and the presence of other congenital anomalies (OR 2.57, 95% CI 1.38-4.87) were associated with an independent higher odds of a child having CH. Conversely, maternal hypertension (OR 0.22, 95% CI 0.09-0.48), older maternal age at delivery (OR 0.93, 95% CI 0.89-0.97), and having more abortions (OR 0.80, 95% CI 0.67-0.95) were negatively correlated with CH. CONCLUSIONS: Multiple parental, socioeconomic, and child-related factors were associated with higher odds for developing CH. These results can be utilized to guide parental counseling and management, and direct social education and prevention programs.

Endoscopic endonasal skull base surgery during the COVID-19 pandemic: A developing country perspective.

BACKGROUND: Although primarily a respiratory disorder, the coronavirus pandemic has paralyzed almost all aspects of health-care delivery. Emergency procedures are likely continuing in most countries, however, some of them raises certain concerns to the surgeons such as the endoscopic endonasal skull base surgeries. The aim of this study is to present the current situation from a developing country perspective in dealing with such cases at the time of the COVID-19 pandemic. METHODS: A cross-sectional analytical survey was distributed among neurosurgeons who performed emergency surgeries during the COVID-19 pandemic in Cairo, Egypt, between May 8, 2020, and June 7, 2020. The survey entailed patients' information (demographics, preoperative screening, and postoperative COVID-19 symptoms), surgical team information (demographics and postoperative COVID-19 symptoms), and operative information (personal protective equipment [PPE] utilization and basal craniectomy). RESULTS: Our survey was completed on June 7, 2020 (16 completed, 100% response rate). The patients were screened for COVID-19 preoperatively through complete blood cell (CBC) (100%), computed tomography (CT) chest (68.8%), chest examination (50%), C-reactive protein (CRP) (50%), and serological testing (6.3%). Only 18.8% of the surgical team utilized N95 mask and goggles, 12.5% utilized face shield, and none used PAPRs. Regarding the basal craniectomy, 81.3% used Kerrison Rongeur and chisel, 25% used a high-speed drill, and 6.3% used a mucosal shaver. None of the patients developed any COVID-19 symptoms during the first 3 weeks postsurgery and one of the surgeons developed high fever with negative nasopharyngeal swabs. CONCLUSION: In developing countries with limited resources, preoperative screening using chest examination, CBC, and CT chest might be sufficient to replace Reverse transcription polymerase chain reaction. Developing countries require adequate support with screening tests, PPE, and critical care equipment such as ventilators.

Migration of the Distal Catheter of Ventriculoperitoneal Shunts in Pediatric Age Group: Case Series.

BACKGROUND: Ventriculoperitoneal (VP) shunting is the most commonly performed procedure in the treatment of hydrocephalus. VP shunt migration can occur at different sites. The aim of the study was to present different sites of abnormal distal shunt location, pathophysiology, and the management in each situation. METHODS: Between 2014 and 2017, all patients with hydrocephalus in the Department of Neurosurgery, Cairo University, were gathered prospectively. All pediatric patients below the age of 12 years with shunt migration of the distal end of the VP shunt were identified. RESULTS: Of 1092 patients operated on by the VP shunt between 2014 and 2017, 15 presented with shunt dysfunction because of distal shunt migration (6 anal, 3 scrotal, 1 colon, 1 peroral, 1 upper lumbar extrusion, 1 paraspinal, 1 penile, and 1 umbilical). Especially upper lumbar extrusion and paraspinal shunt location are extremely rare. All the 15 patients were treated successfully with VP shunts and prospectively followed until they presented with complications on different occasions. CONCLUSIONS: Peritoneal complications are among the most common causes of VP failure. We present a rare complication where the shunt migrates outside the peritoneal cavity elsewhere with ambiguous pathogenesis. Special considerations have to be appointed during the shunt revision surgeries of these cases.
