Radiological and clinical aspect of Caudal regression syndrome associated with dorsal hemivertebra without maternal diabetes.

Caudal regression syndrome (CRS) is a rare genetic disorder affecting less than 0.1%-0.5% of newborns that manifests as the total or partial absence of lower vertebral structures including the sacral spine. The etiology of CRS remains elusive, but there is compelling evidence supporting a genetic predisposition and a correlation with maternal diabetes. This study presents the case of a 7-year-old girl exhibiting symptoms consistent with CRS including lower limb deficits, abnormal gait, urinary incontinence, and scoliosis. The findings from an MRI scan revealed notable anomalies such as hemivertebra in the dorsal spine, renal deformities, and the absence of secondary neurulation elements in the spine. We chose to delay the hemivertebra surgery because the scoliosis was not highly pronounced. Rather, we directed the child to the urology department for the management of her kidney deformities. This case contributes to the understanding of CRS and underscores the importance of comprehensive diagnostic approaches in elucidating its complex manifestations.

Surviving against the odds: exploring the clinical and radiological features of iniencephaly compatible with life. Illustrative case.

BACKGROUND: Iniencephaly is a rare neural tube defect (NTD) characterized by deformities in the occiput and inion, along with rachischisis in the cervical and thoracic spine, resulting in the head appearing in retroflexion. OBSERVATIONS: This report details the case of a female newborn who underwent surgery for an encephalocele. She survived up to 6 months, exhibiting good overall health, although she displayed physical abnormalities, including facial deformity, a short neck, and minor spasms in all limbs. Both cardiovascular and abdominal assessments remained stable, and imaging revealed defects in the occipital bone, a large cephalocele, and spinal dysraphism. LESSONS: Although iniencephaly is generally incompatible with life, a few cases have been reported otherwise. Our patient, one of these notable exceptions, remains alive at 6 months old, possibly due to the lack of major vascular deformities. However, she does exhibit significant psychomotor retardation.

Giant supra and retrosellar glioependymal cyst presenting with only precocious puberty. Clinical study and review of the literature.

INTRODUCTION AND IMPORTANCE: Intracranial glioependymal cysts are an uncommon type of neuroepithelial cyst and are encountered much less frequently than arachnoid cysts. These cysts primarily manifest within the parenchyma of the brain, although exceedingly rare instances have been reported in the lateral ventricles. CASE PRESENTATION: We present a highly unusual case of a glioependymal cyst in a 7-year-old girl. The glioependymal cyst was located in the midline in the suprasellar region and extended to the upper clivus region. Its only manifestation was precocious puberty. We performed endoscopic fenestration of the cyst, leading to a return of hormonal levels to normal and a slight reduction in cyst size. CLINICAL DISCUSSION: A comprehensive search of the Medline database revealed only a few documented cases of glioependymal cysts (fewer than 30 cases). Remarkably, the majority (if not all) were located laterally rather than in the midline of the brain. Endoscopic fenestration and biopsy are effective and confirm the diagnosis. CONCLUSION: This instance of a rare glioependymal cyst located in the midline, spanning the suprasellar and retrosellar regions, is an uncommon occurrence. Its sole presentation was precocious puberty. The successful management of this condition was achieved through an endoscopic approach, leading to the normalization of endocrine abnormalities.

Efficacy of apraclonidine eye drops in treating ptosis secondary to myasthenia gravis: A pilot clinical trial.

INTRODUCTION/AIMS: Most patients with myasthenia gravis (MG) develop ocular manifestations during their illness and up to 22% may have isolated ocular myasthenia gravis (OMG). Apraclonidine elevates the eyelid by activating alpha-2 receptors on Muller's muscle, an accessory eyelid elevator muscle. In this study we evaluate the effect of apraclonidine in alleviating ptosis secondary to MG. METHODS: This clinical trial (NCT05045248) was done at the American University of Beirut Medical Center. Patients with ptosis secondary to MG were administered two drops of apraclonidine 0.5% solution to the most affected eye. We measured palpebral fissure height (PF), marginal reflex distance-1 (MRD1), marginal reflex distance-2 (MRD2), and levator function (LF) before drug administration and at 1, 5, 30, and 60 minutes after administration. RESULTS: Ten participants were enrolled in the study. Improvement in all eyelid measurements was noted in all participants as early as 1 minute after apraclonidine administration. From baseline to 60 minutes after administration, average PF increased from 8.8 ± 1.9 mm to 14.2 ± 2.6 mm, MRD-1 from 1.7 ± 1.4 mm to 5.4 ± 2.9 mm, MRD-2 from 7.1 ± 1.3 mm to 8.8 ± 1.7 mm, and LF from 13.4 ± 2.9 mm to 17.5 ± 2.4 mm. All increases were statistically significant. DISCUSSION: Apraclonidine may alleviate ptosis secondary to MG and may be an effective alternative treatment for this group of patients.

Guillan-barre syndrome during COVID-19 pandemic: a case series from Syria.

The Coronavirus was first discovered in December 2019 and quickly it turned into a pandemic called coronavirus disease 2019 (COVID-19). The main symptoms of infection with this virus were constitutional and respiratory symptoms. However, one-third of COVID-19 patients also developed neurologic manifestations, including Guillan-Barre syndrome (GBS), which was one of the most critical complications. Case presentation: In this paper, the authors present seven patients who suffered from GBS after being infected with the Coronavirus or in conjunction with the infection. Nerve conduction studies showed axonal type in four patients, and demyelinating type in three patients. Neurological symptoms were the initial symptoms in two patients and the presence of COVID-19 was later discovered. Most of the patients had an excellent recovery. Conclusion: In the medical literature, many articles have mentioned the association of GBS with the Coronavirus, and it is considered the most common peripheral neurologic complication for the virus, but this article is considered one of the very few articles that were published from the Middle East, especially from Syria. Guillain-Barre's occurrence after infections is known, and the Coronavirus is one of the most important viruses of the era, which incited an increase in the number of Guillain-Barre patients.

MRI-negative myelitis associated with cerebral venous thrombosis after COVID-19 infection.

Transverse myelitis and cerebral venous thrombosis represent some of the described neurological complications of coronavirus disease. A woman in her early 30s presented with headache, left-sided sensory symptoms and voiding difficulty. The patient also reported dry cough, fever, nasal congestion, anosmia and ageusia 2 weeks before presentation. The clinical examination showed sensory disturbances on the left side of the body, starting from the lower abdomen and extending to the left leg, which was consistent with transverse myelitis. The laboratory assessment confirmed a previous infection with coronavirus disease and excluded autoimmune entities. Radiological investigations revealed left transverse sinus thrombosis with no spinal cord abnormalities. The treatment was started with therapeutic anticoagulation and intravenous high-dose steroids. The patient showed significant improvement, and the neurological deficits resolved after 3 months. This is the first documented case of imaging-negative myelitis associated with cerebral venous thrombosis after coronavirus disease.

Traditional medicines and their common uses in central region of Syria: Hama and Homs - an ethnomedicinal survey.

CONTEXT: Since ancient times, traditional Arabic medicine (TAM) has been used to treat various diseases in Syria. They are cost-effective with fewer side effects and are more suitable for long-term use compared with chemically synthesized medicines. In addition, the scientific importance is manifested, as this survey proceeds, for the purposes of verifying and documenting these traditional medicines and their common uses. OBJECTIVE: We conducted ethnobotanical and ethnomedicine research on plants traditionally used to treat various diseases in central region of Syria. METHODS: Information was collected from 2019 to 2021 from the cities of Homs and Hama and their villages, which are two governorates located in central Syria, after interviews with traditional practitioners called Attarin, and many other people. Plant specimens were collected according to different references concerning medicinal plants of Syria, to document the traditional uses of plants at least two of the traditional healers and three other people were asked. RESULTS: In this survey, we listed 76 medicinal plants belonging to 39 families in alphabetical order with the parts used and the method of preparation according to their therapeutic use, which are used to treat 106 ailments. CONCLUSIONS: Many of the uses of medicinal plants mentioned in this survey are still under study. There is no doubt that this study will provide new data that could contribute to further pharmacological discoveries by identifying the active ingredients and their mechanism of effect by doing additional pharmacological work to confirm the alleged biological activities of these plants.

Proapoptotic and Antiangiogenic Activities of Arctium Lappa L. on Breast Cancer Cell Lines.

In this study, the bioactivity-guided fractionation was conducted on the aerial parts of Arctium lappa L. and then the extracts were tested in vitro on breast cancer (MCF-7), colorectal cancer (HCT-116), and normal cells (EA.hy926). The n-hexane fraction (EHX) of the ethanolic extract showed strong activity against both MCF-7 and EA.hy926 cell lines (IC50 values: 14.08 ± 3.64 and 27.25 ± 3.45 µg/mL, respectively). The proapoptotic activity of EHX was assessed using MCF-7. Morphological alterations were visualized using Hoechst staining and a transmission electron microscope. Cancer cell signal transduction pathways were investigated, and EHX significantly upregulated p53, TGF-ß, and NF-κB. Furthermore, EHX was found to disrupt the metastatic cascade of breast cancer cells by the inhibition of cell proliferation, migration, invasion, and colonization. The antiangiogenic activity of EHX fraction showed potent inhibition of rat aorta microvessels with IC50 value: 4.34 ± 1.64 µg/mL. This result was supported by the downregulation of VEGF-A expression up to 54%. Over 20 compounds were identified in EHX using GC-MS, of which stigmasterol, ß-sitosterol, and 3-O-acetyllupeol are the major active compounds. Phytochemical analysis of EHX showed higher phenolic and flavonoid contents with a substantial antioxidant activity. In conclusion, this work demonstrated that A. lappa has valuable anticancer activity and antiangiogenic properties that might be useful in breast cancer therapy.

Cat's whiskers (Orthosiphon stamineus) tea modulates arthritis pathogenesis via the angiogenesis and inflammatory cascade.

BACKGROUND: Orthosiphon stamineus is used traditionally to treat gout, arthritis, and inflammatory related conditions. The in vitro anti-inflammatory effects of the plant have been scientifically investigated. The goal of the present study was to evaluate the potential of the 50% ethanol extract of O. stamineus (EOS) to treat rheumatoid arthritis. METHODS: Anti-arthritic activity was assessed using the in vitro heat denaturation test and the (FCA)-induced arthritis model. Efficacy was assessed by measurements of paw edema and granulation, X-ray radiography, fluorescence molecular tomography (FMT), and histological evaluation. Levels of (TNF-α), interleukin-1 (IL-1), and (COX-1 and COX-2) were analyzed in vitro in lipopolysaccharide (LPS)-stimulated human macrophage (U937). TNF-α and IL-1 levels in the serum samples of arthritic rats were also measured using an ELISA kit. RESULTS: Treatment with EOS resulted in dose-dependent inhibition of paw edema in acute and chronic models of inflammation. It also inhibited significantly the production of TNF-α, IL-1 COX-1, and COX-2 in the LPS-stimulated U937 macrophages. EOS significantly suppressed FCA-induced paw edema as well as the serum levels of TNF-α and IL-1. X-rays of the synovial joint of the hind leg showed considerable improvement in joint integrity and recovery of tibia-talus bones from degeneration and osteoporotic lesions. Histology of proximal interphalangeal joints of EOS-treated animals showed obvious protection of cartilage and soft tissue. Finally, FMT analysis strongly supported the anti-arthritic effect of EOS. EOS had high phenolic and total flavonoid content as well as strong antioxidant activity. CONCLUSIONS: Results illustrated that the anti-arthritic properties of O. stamineus could be beneficial for prevention and management of rheumatoid arthritis and other chronic inflammatory disorders.
