The larynx, or voice box, is located in the neck and contains vocal cords that produce sound. It has three main functions: phonation, respiration, and protection of the lower respiratory tract. The larynx is composed of cartilage, including the thyroid, cricoid, and arytenoid cartilages which connect through joints allowing movements like abduction and adduction of the vocal cords. Intrinsic muscles like the posterior cricoarytenoids abduct the vocal cords while muscles like the thyroarytenoid laterally adduct the vocal cords to modulate vocal pitch and volume. The larynx plays a crucial role in both voice production and airway protection.
The larynx is located in the midline of the neck between the third and sixth cervical vertebrae. It consists of a framework of cartilages connected by ligaments and lined with mucous membrane. The main cartilages are the thyroid, cricoid, epiglottis, and paired arytenoid and corniculate cartilages. The larynx contains intrinsic muscles that control vocal fold movement and tension for phonation and airway protection. It receives blood supply from the superior and inferior thyroid arteries and innervation from the recurrent and superior laryngeal nerves of the vagus nerve. Lymphatic drainage divides the larynx into supraglottic and subglottic regions.
The larynx contains nine cartilages that form its framework, including the thyroid, cricoid, and arytenoid cartilages. It has two unpaired cartilages, the epiglottis and thyroid, and three paired cartilages on each side, the arytenoids, corniculates, and cuneiforms. The larynx has two openings, the laryngeal inlet and cavity, and houses the vocal cords. It contains several intrinsic muscles that control functions like vocalization through adduction and abduction of the vocal cords. The larynx is supplied by the recurrent laryngeal nerve and its examination and various pathologies are discussed.

A patient presented with alternating diarrhea and constipation, abdominal pain, and nausea for the past 3 months. CT scan of the abdomen and pelvis was advised and showed findings consistent with diverticulosis. Diverticulosis is common in older individuals, especially those with a low-fiber diet, and is characterized by small pouches or outgrowths of the colonic wall that can sometimes cause symptoms or complications but are often asymptomatic.
1. Sinusitis is inflammation of the paranasal sinuses that can be acute, subacute, or chronic depending on duration. Chronic sinusitis persists for over 3 months due to incomplete resolution of acute sinusitis.
2. Chronic sinusitis is characterized by chronic postnasal mucopurulent discharge, with or without recurrent headache or facial pain. It is usually caused by anatomical or pathological obstruction to sinus drainage.
3. Treatment involves antibiotics, nasal decongestants, steroids, and surgery to address predisposing causes and improve drainage when refractory to medical management. Functional endoscopic sinus surgery is commonly used to surgically treat chronic sinusitis.
The nasal cavity is divided by the nasal septum and contains three meatuses. The nasal cavity receives blood supply from various arteries including the sphenopalatine artery. There are four paired paranasal sinuses located around the nasal cavity: the maxillary, frontal, ethmoid, and sphenoidal sinuses. The osteomeatal complex and meatus are involved in sinus drainage. Certain ethmoid air cells like Haller and Onodi cells can affect sinus drainage or structures like the optic nerve.
This document discusses laryngeal trauma, including causes such as automobile accidents or strangulation. It describes the pathology of laryngeal injuries, which can range from bruising to fractures of cartilages like the thyroid or cricoid. Clinical features include respiratory distress, voice changes, pain with swallowing. Diagnosis involves laryngoscopy or CT imaging. Treatment may involve ventilation, steroids, antibiotics, or open reduction surgery to repair fractures or lacerations. Complications can include stenosis, perichondritis, abscess or vocal cord paralysis.
The document provides guidance for conducting a Maternal Neonatal Tetanus Elimination initiative in 2022 in Khyber Pakhtunkhwa province of Pakistan. It outlines the campaign strategy which involves immunizing women of reproductive age between 15-49 years old in 3 rounds with a 0, 1, and 6 month interval. Record keeping procedures are described including maintaining vaccination registers and cards for each woman. Proper vaccine storage and handling, injection safety, and adverse event monitoring are also reviewed.
The document discusses laryngeal trauma. It begins by describing the anatomy and functions of the larynx. It then covers the causes, symptoms, diagnosis, and management of laryngeal injuries. Common causes include blunt injuries from accidents, strangulation, or penetrating injuries. Diagnosis involves examination, imaging like CT scans, and direct laryngoscopy. Injuries are classified into four groups based on severity. Minor injuries may be observed while more severe injuries involving exposed cartilage or vocal cord immobility require surgical exploration and repair to restore the laryngeal framework and phonation.
The parapharyngeal space is pyramidal in shape, located between the base of skull and hyoid bone. It has medial, posterior and lateral relations. Infection can occur from the pharynx, teeth, ear or other head and neck spaces. Clinical features depend on the involved compartment and include tonsillar prolapse, trismus, swelling and pain. Diagnosis is by CT or MRI. Abscesses are drained surgically under general anesthesia via an incision below the mandible. Complications include airway obstruction, thrombophlebitis, infection spread and carotid injury. Treatment involves intravenous antibiotics and surgical drainage.
A patient presented with complaints of alternating diarrhea and constipation for the past 3 months along with abdominal pain and nausea. CT abdomen and pelvis was advised which showed findings consistent with diverticulosis. Diverticulosis is common in older individuals in western countries, with the sigmoid colon most often affected. It is usually asymptomatic but can sometimes cause alternating diarrhea and constipation, and imaging plays an important role in diagnosis.
The nasal cavity is divided by the nasal septum. The lateral walls are formed by contributions from several bones and contain three turbinates that divide the cavity into three meati. The sphenopalatine artery and its branches supply the nasal cavity. Paranasal sinuses surround the nasal cavity. Several anatomical structures related to sinus drainage were described, including the osteomeatal complex, hiatus semilunaris, and various meatal openings. Specific ethmoid air cell variations like Haller cells and Onodi cells were also discussed in relation to sinus drainage and surgical risk.
The mandible is composed of two halves that unite at the symphysis menti. Each half contains a horizontal body, vertical ramus, and angle. The ramus has two projections - the coronoid process which attaches the temporalis muscle, and the condylar process which forms the temporomandibular joint. The mandibular canal runs through the ramus and body, containing the inferior alveolar vessels and nerve. There are 20 deciduous teeth in children and 32 permanent teeth in adults, with a specific arrangement in each dental quadrant.
The middle ear is a six-walled air-filled cavity located in the petrous part of the temporal bone between the inner and outer ear. It has three divisions - the epitympanum above the eardrum, the mesotympanum opposite the eardrum, and the hypotympanum below the eardrum. The middle ear contains the three ossicles (malleus, incus, stapes) that transmit sound vibrations from the eardrum to the inner ear. It is lined by epithelium and contains the tensor tympani and stapedius muscles that help dampen loud sounds. Blood supply comes from branches of the maxillary and posterior auricular arteries.

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.

NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.

Anatomy of larynx details with diagrams,
1.
2.
3. LARYNX
Lies in front of hypopharynx opposite the 3rd to 6th
cervical vertebrae.
Below the hyoid bone and superior to the trachea in
the midline of neck.
Larynx consists of :
1- Cartilages
2- Muscles
3- Membranes & ligaments
Male Femla
e
Length 44 mm 36 mm
Transverse diameter 43 mm 41 mm
AP diameter 36 mm 26 mm
5. CARTILAGES
Thyroid cartilage
Largest of all.
Lies against C4-C5.
Formed of Hyaline Cartilage which tends to ossify or
calcify with age .
Its two laminae meet in midline at an angle of 90° in
males & 120° in females.
The fused laminae ends in marked projection in
midline called laryngeal prominence (Adams apple)
Vocal cords attached to the middle of thyroid angle
10. CARTILAGES
Arytenoids
Paired & pyramidal in shape
Base articulates with cricoid
Muscular process directed laterally & attached to intrinsic
laryngeal muscles
Vocal process directed anteriorly, giving attachment to vocal
cord
Apex supports corniculate cartilage
11. Corniculate cartilages (of Santorini) articulating
with the apices of arytenoid cartilages.
Cuneiform cartilages (of Wrisberg) in each
margin of the aryepiglottic fold.
12. JOINTS
Cricoarytenoid joint
A synovial joint
Formed b/w the base of arytenoid & a facet on upper
boder of cricoid lamina
Two types of movements – rotatory & gliding
Cricothyroid joint
A synovial joint
Formed by inferior cornua of thyroid cartilage & a
facet on cricoid cartilage
13. MUSCLES
INTRINSIC
Acting on vocal cords
Abductors: Posterior cricoarytenoid
Adductors: Lateral cricoarytenoid
transverse arytenoid
Tensors: Cricothyroid
Vocalis (internal part of thyroarytenoid)
Acting on laryngeal inlet
Openers: Thyroepiglottic
Closers: Aryepiglottic
Interarytenoid
14. MUSCLES
EXTRINSIC
They connect the larynx to other structures
Primary elevators act directly as they are attached to
thyroid cartilage
Stylopharyngeus, salpingpharyngeus,
palatopharyngeus, thyrohyoid
Secondary elevators act indirectly as they are
attached to hyoid bone
Mylohyoid, digastric, stylohyoid, geniohyoid
Depressors
Sternohyoid, sternothyroid & omohyoid
15. CAVITY OF LARYNX
Vocal folds
(true vocal cords)
two pearly white sharp bands extending from thyroid angle to
vocal processes of arytenoids.
Vestibular folds
(false vocal cords)
fold of mucous membrane containing vestibular ligament
Ventricle
(sinus of larynx)
a deep elliptical space b/w vestibular & vocal folds, also
extending a short distance above & lateral to vestibular fold
.
16. SACCULE
Diverticulum of mucous membrane.
Starts from the anterior part of the ventricle
Extends upwards b/w vestibular folds & lamina
of thyroid cartilage.
May form laryngocele.
Epithelium of mucous membrane is ciliated
columnar except over the true cords where it is
stratified squamous type
17. LYMPHATIC DRAINAGE
Above vcs – upper deep cervical L/nodes
Below vcs – prelaryngeal & pretracheal & then to
lower deep cervical L/nodes
Nerve supply
VAGUS NERVE through RLN & SLN
Motor: all muscles RLN except cricothyroid
Cricothyroid external LN
Sensory: above vcs internal LN
Below vcs RLN
18. SPACES OF LARYNX
Pre-epiglottic space
Anteriorly – upper part of thyroid cartilage & thyrohyoid
membrane
Posteriorly – infrhyoid epiglottis & quadrangular membrane
Above – hyoepiglottic ligament
Laterally continuous with paraglottic space
Paraglottic space
Laterally – thyroid cartilage
Medially – ventricle & quadrangular membrane
Posteriorly – mucosa of pyriform fossa
Reinke’s space
A potential space under the epithelium of VCs. It is bounded
above & below by arcuate lines
19. FUNCTIONS OF LARYNX
1- Protection of lower airways:
By three ways
i- sphencteric closure of laryngeal opening by
a- laryngeal inlet b- false cords c- true cords
ii- cessation of respiration (through reflex by 9th nerve)
iii- cough reflex ( to expel a foreign particle)
2- Respiration
20. 3- Phonation
a- VCs kept adducted
b- Infraglottic pressure generated by exhaled air
c- The air force open the cords & is released as small puffs
which vibrate the cords & produce the sound
4- Fixation of chest
when larynx is closed, chest wall gets fixed & various
thoracic & abdominal muscles can then act best. This function
in pulling, climbing, micturition, defaecation & childbirth.
