Broken Endodontic Instrument Caused Inferior Alveolar Nerve Paraesthesia: A Case Report.

Abstract:

A healthy 55-year-old man was referred to the Department of Endodontics, Oral and Dental Healthy Hospital, Eskişehir suffering from pain and paraesthesia in the left lower lip and chin.A panoramic radiograph revealed the presence of broken endodontic instrument beyond the apex of the mandibular left third molar. A cone beam computed tomography (CBCT) examination was undertaken, which revealed that the broken instrument was inside the mandibular canal. Damage to the inferior alveolar nerve (IAN) secondary to extrusion of a broken endodontic instrument was diagnosed. Extraction of the tooth was decided and the patient was prescribed with 1 mg/kg/day prednisone 2 times/day, once-daily regimen, and 150 mg/day pregabalin, two doses per day, monitoring the progress with periodic follow-up visits. One month after the incident, the signs and symptoms were gone. The complete resolution of the paraesthesia and the control of pain achieved in the present case suggest that s...

Frontal Sinus Cyst Surgery Complicated by Central Retinal Artery Occlusion

Abstract:

Central retinal artery occlusion (CRAO) is a retinal ischemic disorder associated with sudden loss of vision and has a poor prognosis. We report a case of CRAO that occurred during frontal sinus surgery involving craniotomy in a patient with a frontal sinus cyst. The prognosis for treatment after the acute phase is generally unfavorable; however, aggressive treatment is recommended for patients with visual acuity of “hand motion” or better within 1 day after onset. This case highlights the need for informed consent prior to nasal or paranasal sinus surgery, including mention of the possibility of CRAO as a complication.

Computational EPAS1 rSNP Analysis, Transcriptional Factor Binding Sites and High Altitude Sickness or Adaptation

Abstract:

The endothetal Per-Arnt-Sim (PAS) domain protein 1 (EPAS1) gene which encodes hypoxia-inducible-factor-2 alpha (HIF2a) is a transcription factor that is involved in the response to hypoxia. EPAS1 has been found to have four (rs56721780, rs6756667, rs7589621, rs1868092) simple nucleotide polymorphisms (SNPs) associated with human disease.These SNPs were computationally examined with respect to changes in potential transcriptional factor binding sites (TFBS) and these changes were discussed in relation to disease and alterations in high altitude adaptation in humans.

Physicochemical and Fatty Acids Composition of Barberry Integerrima Seed

Abstract:

In this study, chemical composition of Barberry integerrima seed and physicochemical properties and fatty acids composition of its oil were determined. The seeds contained 11.4 % oil and protein, moisture, crude fiber and ash contents were 17.0%, 19.1%, 48.8% and 2.9%, respectively. The main fatty acids recognized by gas chromatography were linolenic (ω-3), linoleic (ω-6) and oleic (ω-9) acid (38.3, 37.0, 15.5%, respectively). The density and refractive index of the extracted barberry seed oil were 0.821 and 1.4780, respectively. FFA (% as oleic acid), acid value (mg KOH/g oil), iodine value (g I₂/100 g oil), saponification number (mg KOH/ g oil), and unsaponifiable matter content (%) of the extracted oil from Barberry integerrima seeds were 0.70, 1.4, 180.0, 197.2, and 2.3, respectively. Color of extracted crude oil exhibited red unit 4.9, yellow unit 18.6 and blue unit 1.9, respect...

Vitamin A deficiency Disorders among the Rural Pre-School Children of South India

Abstract:

Vitamin A deficiency (VAD) among the rural pre-school children in India is continues to be a major nutritional problem of public health significance, even after the implementation of national vitamin A prophylaxis programme for more than four decades. The aim of the study was to assess the prevalence of vitamin A deficiency among rural pre-school children of South India.

A Case of Pernio Associated with Cold Agglutinin Positivity in an Unusual Location

Abstract:

Pernio is an inflammatory disease that is usually characterized by the development of cold-induced erythrocyanotic skin lesions located in acral regions. Diagnosis is difficult if lesions are present in rare locations. A 21-year-old female suffering from fatigue presented with a 4-day history of painful, purple lesions on both thighs. She worked as a cashier, wore tight clothing, and was otherwise healthy except for mild obesity. Dermatological examination revealed tender and painful edematous papules and plaques on the outer aspects of her thighs. The patient was diagnosed with pernio based on her medical history, and clinical and histological findings. Laboratory tests were normal except for her cold agglutinin titer (1:4). Pernio rarely occurs on the thigh, except in people who ride horses. However, it sometimes occurs in non-riders depending on lifestyle and environmental conditions. Therefore, lesions in this region must be confirmed by a thorough medical his...

Psychosocial Factors and Comorbidity Associated with Recovery in Bipolar Disorder

Abstract:

Bipolar disorder (BD) is a chronic psychiatric illness impacting patient functioning and quality of life. Medication produces improvement in many patients and remission in some, but there is minimal understanding about why some patients improve and others do not. Our goal was to identify demographic, psychosocial and comorbid variables associated with outcomes in BD. Charts of 121 outpatients treated with medication and supportive psychotherapy were reviewed. Forty four percent attained euthymia for 12 months while 56% did not. Poorer outcome was associated with economic stress, missed appointments, life stress, and presence of pain (p < 0.05). Those employed were more likely to improve (p < 0.02). Patients with BP-II reported more frequent life stressors, headache and use of alcohol (p <0.05) and were less likely to achieve euthymia than BP-I. Gender, education, and co-morbid medical illness did not affect results. Our findings suggest that poorer o...

Cholesterol-Conjugated siRNA Accumulates in the Different Hematopoietic and Lymphoid Cells.

Abstract:

Small interfering RNA (siRNA) based drugs for overcoming multiple drug resistance of hematological malignancies could solve the problem of poor response to the chemotherapy and hight relapse rate. The main factor that significantly limits biomedical application of siRNA is inefficient delivery to target cells and tissues. The attachment of siRNA to molecules, which enter into the cell by natural transport mechanisms, can improve cellular uptake of siRNA. In current study the carrier-free cellular uptake of siRNA containig cholesterol residues conjugated to the 5’-end of the sense strand via oligomethylene linker of various length (here and after Ch-siRNA) was explored. The data demonstrate that cholesterol residue increase the accumulation of siRNA in all tested cell lines and the primary cells. The efficiency of Ch-siRNA accumulation in K562 cells depends greatly on the leangth of the linker connecting cholesterol and siRNA: Ch-siRNAs with linker of 10 - 12 met...

New Antioxidant Flavonoids from the Aerial Parts of Secamone Afzelii

Abstract:

A bioassay-guided fractionation of petroleum ether, EtOAc and n-BuOH soluble parts of the 80% hydromethanol extract was performed to investigate the antioxidant activity of Secamoneafzeliiaerial parts using DPPH free radical scavenging assay. The results revealed that EtOAc and n-BuOH soluble parts have moderate to good DPPH radical scavenging activity (EC₅₀ = 139.3 and 30.5 μg/mL, respectively). Therefore, from the most active fractions of EtOAc and n-BuOH soluble parts were isolated two new flavonoid diglycosides quercetin-3-O-β-d-apiofuranosyl-(1→2)-α-l-rhamnopyranoside and genkwanin-8-C-β-d-apiofuranosyl-(1→2)-β-d-glucopyranoside in addition to nine known compounds (2-10). Their structures were elucidated on the basis ...
