- To detect neurogenic blocking on SFEMG, you need to record 3 spikes simultaneously.
- To detect neurogenic jitter on SFEMG, you need to record 4 spikes simultaneously. If only 3 spikes are recorded, the jitter may be due to triggering issues rather than a neurogenic cause.
- To ascertain that distal and proximal stimulation is of the exact same axon during conduction velocity testing, stimulate distally and proximally simultaneously. If the proximal response disappears with dual stimulation, it indicates collision and the same axon was stimulated.NCS special

The document contains questions and answers regarding neurophysiology techniques. Some key points discussed include:
- Voluntary activity does not influence CMAP amplitude at supramaximal stimulation, except for effects of muscle shortening.
- CMAP satellites can be distinguished from extra discharges by superimposing traces after 3Hz stimulation - satellites will be stable while extra discharges will be variable.
- If CMAP amplitude is unexpectedly low with no nerve damage or PNP, steps should be taken to check stimulation strength, equipment, skin conditions, and perform activation maneuvers before considering anomalies.
- F waves are usually normal in C8 radiculopathy but may be abnormal on the affected side in an ulNCS routine

Non-Invasive ICP Monitoring for NeurosurgeonsDhaval Shukla
油
This presentation delves into the latest advancements in non-invasive intracranial pressure (ICP) monitoring techniques, specifically tailored for neurosurgeons. It covers the importance of ICP monitoring in clinical practice, explores various non-invasive methods, and discusses their accuracy, reliability, and clinical applications. Attendees will gain insights into the benefits of non-invasive approaches over traditional invasive methods, including reduced risk of complications and improved patient outcomes. This comprehensive overview is designed to enhance the knowledge and skills of neurosurgeons in managing patients with neurological conditions.
Invasive systems are commonly used for monitoring intracranial pressure (ICP) in traumatic brain injury (TBI) and are considered the gold standard. The availability of invasive ICP monitoring is heterogeneous, and in low- and middle-income settings, these systems are not routinely employed due to high cost or limited accessibility. The aim of this presentation is to develop recommendations to guide monitoring and ICP-driven therapies in TBI using non-invasive ICP (nICP) systems.

If its not Itch Its not Eczema
Eczema is a group of medical conditions which causes inflammation and irritation to skin.
It is also called as Dermatitis
Eczema is an itchy consisting of ill defined erythremotous patches. The skin surface is usually scaly and As time progress, constant scratching leads to thickened lichenified skin.
Several classifications of eczemas are available based on Etiology, Pattern and chronicity.
According to aetiology Eczema are classified as:
Endogenous eczema: Where constitutional factors predispose the patient to developing an eczema.
Family history (maternal h/o eczema) is often present
Strong genetic predisposition (Filaggrin gene mutations are often present).
Filaggrin is responsible for maintaining moisture in skin (hence all AD patients have dry skin.
Immunilogical factor-Th-2 disease, Type I hypersensitivity (hence serum IgE high)
e.g., Seborrheic dermatitis, Statis dermatitis, Nummular dermatitis, Dyshidrotic Eczema
Exogenous eczema: Where external stimuli trigger development of eczema,
e.g., Irritant dermatitis, Allergic Dermatitis, Neurodermatitis,
Combined eczema: When a combination of constitutional factors and extrinsic triggers are responsible for the development of eczema
e.g., Atopic dermatitis
Extremes of Temperature
Irritants : Soaps, Detergents, Shower gels, Bubble baths and water
Stress
Infection either bacterial or viral,
Bacterial infections caused by Staphylococcus aureus and Streptococcus species.
Viral infections such as Herpes Simplex, Molluscum Contagiosum
Contact allergens
Inhaled allergens
Airborne allergens
Allergens include
Metals eg. Nickle, Cobalt
Neomycin, Topical ointment
Fragrance ingredients such as Balsam of Peru
Rubber compounds
Hair dyes for example p-Phenylediamine
Plants eg. Poison ivy .
Atopic Dermatitis : AD is a chronic, pruritic inflammatory skin disease characterized by itchy inflamed skin.
Allergic Dermatitis: A red itchy weepy reaction where the skin has come in contact with a substance That immune system recognizes as foreign substances.
Ex: Poison envy, Preservatives from creams and lotions.
Contact Irritant Dermatitis: A Localized reaction that include redness, itching and burning where the skin has come In contact with an allergen or with irritant such as acid, cleaning agent or chemical.
Dyshidrotic Eczema: Irritation of skin on the palms and soles by
clear deep blisters that itch and burn.
Clinical Features; Acute Eczema:- Acute eczema is characterized by an erythematous and edematous plaque, which is ill-defined and is surmounted by papules, vesicles, pustules and exudate that dries to form crusts. A subsiding eczematous plaque may be covered with scales.
Chronic Eczema:- Chronic eczema is characterized by lichenification, which is a triad of hyperpigmentation, thickening markings. The lesions are less exudative and more scaly. Flexural lesions may develop fissures.
