Herpes zoster of posterior division of mandibular branch of trigeminal nerve.

Herpes zoster is a disease caused by the reactivation of dormant varicella zoster virus present in the sensory root ganglion. It presents with a vesicular rash on an erythematous base similar to that seen in classical varicella, however, with only a single dermatomal distribution. The rash is usually seen throughout the affected dermatome as the dorsal root ganglia for each dermatome are clustered together.

Medical interventions for chronic rhinosinusitis in cystic fibrosis.

Background: Chronic rhinosinusitis frequently occurs in people with cystic fibrosis. Several medical interventions are available for treating chronic rhinosinusitis in people with cystic fibrosis; for example, different concentrations of nasal saline irrigations, topical or oral corticosteroids, antibiotics - including nebulized antibiotics - dornase alfa and modulators of the cystic fibrosis transmembrane conductance regulator (CFTR) (such as lumacaftor, ivacaftor or tezacaftor). However, the efficacy of these interventions is unclear.

Otoneurological presentations of COVID-19.

COVID-19 usually begins with respiratory symptoms but may also cause neurological disturbances by direct (viral invasion) or indirect (immune-mediated) mechanism. Common neurological injury described in the literature include infectious toxic encephalopathy, viral encephalitis and Guillain-Barré syndrome. We present two cases diagnosed with COVID-19 who presented with isolated neurological deficit along facial nerve and vestibular nerve.

Middle-ear disease in children with cleft palate.

Objective: The objective of this review is to summarize all aspects of middle ear diseases in children with cleft palate (CP).

Methods: PubMed, Scopus, The Cumulative Index to Nursing and Allied Health Literature (CINAHL) and The Cochrane Library were searched for English-language randomized control trials (RCTs), meta-analyses, systematic reviews and observational studies published through 31st July 2017.

Results: Epidemiology and pathogenesis of middle ear diseases in children with cleft palate have been discussed in this review.

Lumbar sympathectomy techniques for critical lower limb ischaemia due to non-reconstructable peripheral arterial disease.

Background: Critical lower limb ischaemia (CLI) is a manifestation of peripheral arterial disease (PAD) that is seen in patients with typical chronic ischaemic rest pain or patients with ischaemic skin lesions - ulcers or gangrene - for longer than 2 weeks. Critical lower limb ischaemia is the most severe form of PAD, and interventions to improve arterial perfusion become necessary. Although surgical bypass has been the gold standard for revascularisation, the extent or the site of disease may be such that the artery cannot be reconstructed or bypassed.

A novel screening tool (Karanth's test) for vitamin B12 deficiency: a pilot study.

Background: No practical tests are currently available for screening vitamin B12 deficiency because the available techniques are invasive, expensive, and require a particular level of infrastructure and service that is not available in all places such as rural areas. Thus, we have examined the efficacy of a novel method (Karanth's test) for identifying people with vitamin B12 deficiency as part of a pilot study.

Methods: An observer-blind study was conducted on 83 consenting patients from a tertiary teaching hospital whose blood was drawn for estimation of serum vitamin B12 over a 2-month period.
