“…7 Nervous system involvement has been reported between 2.7% and 17.8% in brucellosis cases. 5 In their study including 60 brucellosis patients, Sanivar et al 5 found impairment in EMG in all patients and claimed that brucellosis may effect on the nervous system, including clinical or subclinical peripheral neuropathy. Although the prevalence of optic nerve involvement was reported as 10% in brucellosis cases, these reports are generally in the form of case reports in the literature.…”

“…3 Although optic neuritis cases due to brucellosis were reported less frequently, nervous system involvement has been reported to occur between 2.7% and 17.8% of brucellosis patients in general. 5 Moreover, electromyography (EMG) studies have shown that subclinical peripheral neuropathy can also be observed in brucellosis. 6 To investigate if there is microinvasive involvement in the optic nerve and choroid due to brucellosis, we evaluated choroidal thickness and retinal nerve fiber layer (RNFL) analysis in patients with brucellosis in the acute stage.…”

Introduction This study aims to detect changes in choroidal thickness and retinal nerve fiber layer (RNFL) thickness in acute stage brucellosis. Methods Fnewly diagnosed patients with acute brucellosis and 19 healthy individuals as control group were included in the study. Choroidal thickness and RNFL thickness were measured using the Spectral Domain Cirrus OCT Model 400 (Carl Zeiss Meditec, Jena, Germany) for each participant in the patient and control group. Results In the brucella group, in the right eyes, the mean nasal choroidal thickness was 272.77 ± 50.26 μm ( p = 0.689), the mean subfoveal choroidal thickness was 321.14 ± 33.08 μm ( p = 0.590), the mean temporal choroidal thickness was 278.86 ± 48.84 μm ( p = 0.478), and the mean RNFL thickness was 90.43 ± 8.93 μm ( p = 0.567). In the left eyes, the mean nasal choroidal thickness was 282.29 ± 48.93 μm ( p = 0.715), the mean subfoveal choroidal thickness was 316.79 ± 39.57 μm ( p = 0.540), the mean temporal choroidal thickness was 284.93 ± 50.57 μm ( p = 0.392), and the mean RNFL thickness was 92.64 ± 8.95 μm ( p = 0.813). Conclusion No difference was found between the control and the brucella groups regarding to all choroidal regions and RNFL thickness.

Purpose of reviewBrucellosis is one of the most common zoonosis worldwide, affecting 500 000 people, annually. Neurobrucellosis incidence is approximately 4%, and it is almost always heterogeneous. As there are no typical clinical features, its diagnosis is frequently misdiagnosing by other infections.Recent findingsNeurobrucellosis picture includes meningitis, meningoencephalitis, encephalitis, cranial neuropathies, intracranial hypertension, sinus thrombosis, hemorrhages radiculitis, peripheral neuropathy, myelitis, and psychiatric manifestations. The diagnosis should be based on symptoms and signs suggestive of neurobrucellosis, not explained by other neurological disease, cerebrospinal fluid analysis, a positive Brucella serology or culture, and a response to specific antibiotics, with a significant improvement of cerebrospinal fluid parameters.SummaryNeurobrucellosis can be insidious, and despite its global distribution, it is still unrecognized and frequently goes unreported. The understanding of the current epidemiology is necessary for eradication of the disease in humans, as well as the disease control in animals and prevention based on occupational hygiene and food hygiene.

“…Whether the cause is an immune process or a cytokine storm, ultimately COVID-19 can affect the peripheral nervous system. Subclinical peripheral nervous system involvement can be seen in some chronic diseases or infectious diseases 7,8 . Subclinical involvement of peripheral nerves can be described as abnormality in nerve conduction studies without symptoms associated with peripheral nervous system involvement 7,8 .…”

Objective: Neurological diseases related to the coronavirus disease (COVID-19) are known. In this study, it was aimed to find out whether the peripheral nervous system is affected in patients with a history of COVID-19 (post COVID-19) without neurological findings. Methods: Patients with a positive history of the nose swap polymerase chain reaction test and clinical signs of COVID-19 (post COVID-19 patients), and controls who have not had COVID-19 were included in this retrospective cohort study. Neurological examinations of post-COVID-19 patients and controls should have been normal. Nerve conduction studies including median, ulnar, posterior tibial and peroneal nerves were applied to all participants. Results: Thirty controls (14 males, 16 females) and 32 post COVID-19 patients (19 males, 13 females) were included. The mean ages of postCOVID-19 patients and controls were 49.7±10.9 and 38.0±7.6 years, respectively. Age and gender were not different between post COVID-19 patients and controls (p=0.122, p=0.316122). Nerve conduction study findings of median, ulnar, posterior tibial and sural nerves were not different between the two groups (p>0.05). Conclusion: This study may show that routine nerve conduction studies are not subclinically affected in post COVID-19 patients without neurological findings.
