Intraosseous malignant peripheral nerve sheath tumor at the frontal bone in a child: a rare cause of proptosis.

We report a nine-year-old male having malignant peripheral nerve sheath tumor (MPNST) of the frontal bone, represented with a twelve-month history of ptosis and proptosis in his right eye and enlarged rapidly in the last three months. Except for slight numbness at his one-third of the right forehead, he had no neurological deficit. The patient's both eyes were having normal eye movements, and he had no visual acuity or field loss. After surgery, we observed the patient with no recurrence for 4 years.

Effect of the "Time to Surgery" on Civil Cranial Gunshot Injuries: Syria War.

ABSTRACT: Studies on cranial gunshot injuries in the Syrian war are present in the literature. However, the effect of surgical timing on the clinical outcomes of patients undergoing surgical treatment has not been discussed extensively. In this study, the time from injury to surgery is called "time to surgery." Kilis, a city close to Aleppo, Afrin, and Azez, where the conflicts in Syria are intense, is one of the cities where the first emergency treatments were administered. This study aimed to evaluate patients who underwent surgery in Kilis State Hospital due to cranial gunshot injury in the Syrian war and to investigate the effect of surgical timing on mortality and Glasgow Outcome Score.Surgical treatment was applied to 42 (32.8%) patients in the first 4 hours, 64 (50%) patients within 4 to 24 hours, and 22 (17.2%) patients between 24 hours and 3 days. As the time to surgery decreased, the good Glasgow Outcome Score (GOS) (4-5) outcome rates increased. The differences in surgical timing and GOS results of patients with Glasgow Coma Score (GCS) <8 and >8 were found to be significant for good GOS results. As the time to surgery decreased for patients with a GCS <8 and >8, mortality rates decreased equally. This result was statistically significant.Our study showed that surgical timing is as important as early intubation, aggressive resuscitation, and admission GCS for both survey and GOS.

Ventriculoperitoneal shunt treatment in a pregnant renal transplant recipient with idiopathic intracranial hypertension: Case report and review of the literature.

Idiopathic intracranial hypertension (IIH) is a relatively uncommon disorder characterised by raised intracranial pressure without an established pathogenesis. Diagnosis of IIH requires the demonstration of symptoms and signs referable only to elevated intracranial pressure; cerebrospinal fluid (CSF) opening pressure >25cm H2O measured in the lateral decubitus position; normal CSF composition; and no evidence for an underlying structural cause demonstrated by using MRI or contrast-enhanced CT scan for typical patients and MRI and MR venography for atypical patients such as man, children and those with low body mass index. We present a 38-year old primigravid renal transplant patient at 7 weeks of gestation who presented with 2 weeks of intense, throbbing, holocranial headache, nausea, vomiting, photophobia, diplopia and progressive visual loss. When medical treatment fails and/or not appropriate to use due to the reported of teratogenic risks in pregnant women, surgical interventions gain importance. In this particular patient, venticuloperitoneal shunt was chosen as the CSF diversion technique. In this case report indications, contraindications in addition to outcomes regarding headache, vision loss and the resolution of papilloedema of the present surgery options for IIH are discussed.

Zinc (Zn) and adipose-derived mesenchymal stem cells (AD-MSCs) on MPTP-induced Parkinson's disease model: A comparative evaluation of behavioral and immunohistochemical results.

Parkinson's disease (PD) is characterized by the loss of dopaminergic neurons and sustained neuroinflammation due to microglial activation. Adipose tissue-derived mesenchymal stem cells (AD-MSCs) secrete neuroprotective factors to prevent neuronal damage. Furthermore, Zn regulates stem cell proliferation and differentiation and has immunomodulatory functions. Our in vivo study aimed to investigate whether Zn affects the activities of AD-MSCs in the MPTP-induced mouse model. Male C57BL/6 mice were randomly divided into six groups (n = 6): Control, Zn, PD, PD+Zn, PD+ (AD-MSC), PD+ (AD-MSC)+Zn. MPTP toxin (20 mg/kg) was dissolved in saline and intraperitoneally injected into experimental groups for two days with 12 h intervals. On the 3rd day, AD-MSCs were given to the right lateral ventricle of the PD+ (AD-MSC) and PD+ (AD-MSC)+Zn groups by stereotaxic surgery. Then, ZnSO4H2O was administered intraperitoneally for 4 days at 2 mg/kg. Seven days post MPTP injection, the motor activities of the mouse were evaluated. Then immunohistochemical analyzes were performed in SNpc. Our results showed that motor activity was lower in Group PD. AD-MSC and Zn administration have improved this impairment. MPTP caused a decrease in TH and BDNF expressions in dopaminergic neurons in Group PD. However, TH and BDNF expressions were more intense in the other groups. MCP-1, TGF-ß, and IL-10 expressions increased in administered groups compared to the Group PD. The present study indicates that Zn's individual and combined administration with AD-MSCs reduces neuronal damage in the MPTP-induced mouse model. In addition, anti-inflammatory responses that emerge with Zn and AD-MSCs may have a neuroprotective effect.
