Networks form the backbone of any healthcare system. Various databases were searched with relevant keywords, data were abstracted, and numerous papers were appraised for this synthesis. This compiled systematic review gives a comprehensive overview of various networks that are found in healthcare, with a special reference to the treatment, referral, and best-practice care of patients. Special support networks, such as Clinical decision support systems, Physician collaboration networks, Telemedicine networks, and Shared healthcare record access, are also described, as these support networks play a pivotal role in improving the quality of healthcare for patients.

<p class="abstract"><strong>Background:</strong> Meniere’s disease is one of the most common causes of chronic recurrent vertigo in general population. Meniere’s disease is closely associated with migraine and migrainous vertigo/ vestibular migraine. Amitriptyline has been classically used in management of Vestibular migraine. This randomized control trail examines the effectiveness of (Tricyclic antidepressant) Amitriptyline 10mg bedtime in patients suffering from Meniere’s disease using a Randomized control trial. This was a randomized, double-blinded, placebo-controlled trial, cross over type with a power of 80% at 5% significance level.</p><p class="abstract"><strong>Methods:</strong> One hundred five patients with definite Meniere’s disease were randomized and assigned to either placebo or trial arm. Trial arm were given Amitriptyline 10 mg bedtime and placebo arm were given a generic Vitamin B-complex tablet. Visual analogue score and standard questionnaires were used to assess the improvements in vertigo, imbalance, dizziness and disease-specific quality of life before and after use of Amitriptyline vs. placebo for period of 10 days each.  </p><p class="abstract"><strong>Results:</strong> Amitriptyline 10mg at bedtime (10mg H.S), produces significant improvement in the vertigo in patients suffering from Meniere’s disease compared to placebo. Chronic imbalance and hearing levels are not affected by the use of the above drug regime. Daytime sedation and weight gain are the most troublesome adverse effects of Amitriptyline at 10mg per day dose. No other serious adverse effects were observed in this research.</p><p><strong>Conclusions:</strong> Low dose bedtime Amitriptyline 10mg appears to be safe and produces improvement in vertigo and disease-specific quality of life in Meniere’s disease patients. </p>

Introduction There is need for any healthcare setup to rapidly identify Sinus headache patients from other cases of Neurological and Primary headaches like Migraine and Chronic Tension-type headache. Materials and Methods 117 cases of confirmed sinusitis were evaluated and analyzed for common traits which could help in the rapid diagnosis of Sinusitis. Results Unilateral, dull aching headache and facial pain, of changing intensity, lasting all day on an average of 4 to 6 hours with a previous short history of the common cold in acute sinusitis is the most common pattern observed in this study. Discussion Unilateral, dull aching headache and facial pain, of variable intensity, lasting all day on an average of 4 to 6 hours along with is highly sensitive criterion (91%) for diagnosis of acute sinusitis. This, along with a history of previous Upper Respiratory tract infection, is useful to rapidly screen patients for acute sinusitis (95% sensitive). Though a subset of other headache cases will also be included by the criteria, imaging or Endoscopy must be done in these positive cases to increase the specificity of the diagnostic criteria.

This chapter gives a broad outline of machine learning and artificial intelligence, and introduces the reader to many novel and latest developments in the field of machine learning. The first half of this compilation provides a comprehensive view of the classical concepts of machine learning. Subsequently, examples of machine learning frameworks are discussed. Deep learning, concepts, models, types, and algorithms in machine learning are elaborated in the subsequent section, followed by a detailed introduction to neural networks, concepts of weights, propagation, and initialization. The final section of this chapter introduces the reader to the fascinating and latest world of cutting-edge applications of machine learning like convolutional neural networks (CNNs), bidirectional long short-term memory (BLSTM), artistic, image-generating AI engines like DALL-E and stable diffusion, music and drama writing AI engines, human-like chatbot ChatGPT, art generation with AI, generative neural network concepts, regenerative neural network, and natural language processing (NLP).
