Dental Pharmacology Lecture Slides on Sialogogues and Antisialogogues by Sanjaya Mani Dixit Assistant Professor of Pharmacology at Kathmandu Medical College
MPDS, or myofascial pain disorder syndrome, is a pain disorder characterized by unilateral pain referred from trigger points in muscles of the head and neck. These trigger points are localized tender areas within taut muscle bands caused by micro- or macro-trauma to the musculoskeletal system. Accumulation of chemicals like lactic acid and prostaglandins in the muscles lowers the pain threshold, leading to MPDS symptoms like pain, limited jaw motion, and joint noises. Diagnosis involves assessing range of motion, palpating muscles for tenderness, and grading joint clicks. Treatment aims to inactivate trigger points, prevent recurrence, and correct perpetuating factors through therapies like physical modalities, anesthesia, pharmacotherapy, and occasionally
The document summarizes non-steroidal anti-inflammatory drugs (NSAIDs). It discusses their mechanism of action by inhibiting cyclooxygenase enzymes and reducing prostaglandin formation, leading to analgesic, anti-inflammatory, and antipyretic effects. NSAIDs are classified based on selectivity for COX-1 and COX-2. Common NSAIDs and their uses for pain relief are described. Adverse effects include gastric irritation and bleeding. Dental considerations advise avoiding NSAIDs if allergic and not using aspirin before and after surgery due to bleeding risk.

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...Oleg Kshivets
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
Muktapishti is a traditional Ayurvedic preparation made from Shoditha Mukta (Purified Pearl), is believed to help regulate thyroid function and reduce symptoms of hyperthyroidism due to its cooling and balancing properties. Clinical evidence on its efficacy remains limited, necessitating further research to validate its therapeutic benefits.
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

3. Saliva
• Saliva has a bactericidal effect, so when low
levels of it are secreted
– the risk of caries increases.
– Not only this, but fungal infections such as
oral candidiasis also can be a consequence of low
salivary flow rates.
– The buffer effect of saliva is also important,
neutralizing acids that cause tooth enamel
demineralization.
5. Cevimeline
Cevimeline has a long-lasting sialogogic action and may have fewer
side effects than pilocarpine.
Cevimeline also enhances lacrimal secretions in Sjögren’s syndrome.
Mechanism of Action
• Muscarinic receptor agonist , exhibits high binding affinity for
muscarinic M3 receptors on lacrimal & salivary gland
epithelium: increases salivation
Elimination
• Half-Life: ~5 hr
• Excretion: Urine 97%; feces 0.5%
6. Cevimeline
Uses
• Xerostomia: Indicated for xerostomia in patients with Sjogren's syndrome
• 30 mg PO TID
A/Es
• Sweating
• Nausea
• Rhinitis
Contraindications
• Uncontrolled asthma, conditions in which miosis is undesirable (eg, narrow-
angle glaucoma, acute iritis)
• Hypersensitivity
7. Pilocarpine
Pilocarpine 5-10 mg dose is given three times daily
in the treatment of xerostomia.
Mechanism of Action
Cholinergic parasympathomimetic, binds with
muscarinic M3 receptors on lacrimal & salivary
gland epithelium hence increases salivation
Half-Life: 0.76-1.35 hr
9. Pilocarpine
A/Es
• Sweating (most common)
• Headache
• Flushing
• Chills
Bethanecol is oral alternative drug with less diaphoresis.
Contraindications
• Uncontrolled asthma, anterior eye inflammation, any time miosis in
undesirable (eg, narrow-angle glaucoma, acute iritis)
• Hypersensitivity
10. Sialogogues Uses
• In the treatment of xerostomia (the subjective
feeling of having a dry mouth)
• Radiotherapy induced xerostomia
– Pilocarpine reduces difficulty in speaking and
swallowing
• to stimulate any functioning salivary
gland tissue to produce more saliva.
• Sjogren’s syndrome- Cevimeline
12. Drugs for treatment of xerostomia
• Parasympathomimetic drugs
• Pilocarpine
• Bethanecol
• Cevimeline
• Chewing gum
13. Antisialogogues
• A substance that reduces the salivary
secretion
• Atropine and anti-cholinergic drugs are known
to decrease salivary secretion
• Propantheline bromide, atropine substitute is
commonly used for the purpose.
14. Antisialogogues Uses
Sialocele
• A sialocele is a localized, subcutaneous cavity
containing saliva.
• They are a relatively common complication
following surgery to the salivary glands
commonly parotidectomy
In this case the sialocele is the result of saliva
draining out of remaining parotid tissue.
