Exploring challenges and mitigation strategies towards practicing Teledentistry.

Background: Since the beginning of the COVID-19 pandemic, many dentists have opted for Teledentistry as a mechanism for patient consultation, oral lesion evaluation, diagnosis, and monitoring. The current study explores the challenges faced and potential solutions proposed by dentists practicing Teledentistry in a developing country like Pakistan.

Methods: A qualitative case study was carried out from January to December 2021.

Eye-of-the-tiger Sign in Neurodegeneration with Brain Iron Accumulation.

A 68-year-old male patient presented to the neurology clinic with tremor, lightheadedness, and a history of syncope. Exam showed mild Parkinsonism. Neuroimaging revealed symmetric lesions of the globus pallidus (the eye-of-the-tiger sign) concerning for neurodegeneration with brain iron accumulation (NBIA).

Crystal structure of (4E)-4-(8-meth-oxy-2H-chromen-2-yl-idene)-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

In the title compound, C20H16N2O3, the phenyl substituent attached to the pyrazole ring makes a dihedral angle of 4.87 (7)° with the rest of the mol-ecule. In the crystal, mol-ecules are connected into inversion dimers of the R 2 (2)(14) type by pairs of C-H⋯O inter-actions.

Crystal structure of (4Z)-4-[(2E)-3-(2-chloro-phen-yl)-1-hy-droxy-prop-2-en-1-yl-idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

In the title compound, C19H15ClN2O2, the pyrazole ring is almost planar (r.m.s.

Crystal structure of (4Z)-4-[(2E)-3-(4-chloro-phen-yl)-1-hy-droxy-prop-2-en-1-yl-idene]-5-methyl-2-phenyl-1H-pyrazol-5(4H)-one.

In the the asymmetric unit of the title compound, C19H15ClN2O2, there are two symmetry-independent mol-ecules, which adopt similar conformations. The largest difference is observed in the dihedral angles between the phenyl and the pyrazole fragments [17.00 (12) and 23.

Crystal structure of (4Z)-4-[(2E)-1-hydroxy-3-(naphthalen-2-yl)prop-2-en-1-yl-idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

In the title compound, C23H18N2O2, the pyrazole ring subtends dihedral angles of 2.01 (13) and 1.55 (10)° with the pendant benzene ring and the naphthalene ring system, respectively.

(4Z)-4-[(2E)-1-Hydr-oxy-3-(4-methoxy-phen-yl)prop-2-en-ylidene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

The title compound, C(20)H(18)N(2)O(4), is a chalcone derivative of pyrazole. The pyrazole ring is inclined at a dihedral angle of 19.29 (12)° to the methoxy-phenyl ring mean plane, and by 1.

The SUNCT syndrome: successfully treated with lamotrigine.

Short-lasting unilateral neuralgiform headache attacks with conjuctival injection and tearing (SUNCT) syndrome is an uncommon headache syndrome. It is usually resistant to treatment. We describe a patient who responded successfully to the anticonvulsant lamotrigine, but not other anticonvulsants commonly used in the treatment of migraine and other cephalgias.
