Children have oral mucosal conditions and other head and neck medical problems which have both similarities and differences to those found in adults .
A wide variety of oral lesions and soft tissue anomalies are detected in children, but the low frequency at which many of these entities occur makes them challenging to clinically diagnose.
THE PRESENTATION INCLUDES VARIOUS ASPECTS IN PEDODONTIC AND PREVENTIVE DENTISTRY THAT PROVIDES both primary and comprehensive, preventive and therapeutic oral health care for infants and children through adolescence, including those with special health care needs.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

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.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

3. Introduction
• The developing dentition and certain systemic
metabolic patterns are peculiar to childhood.
• Periodontal diseases peak their destructive
stages in the middle age , but many of them have
their inception during childhood.
3
4. • There are also gingival and periodontal
disturbances that occur more often in childhood
and are therefore identified with this period.
• The early detection and early treatment are
important from a preventive aspect since, the
prevention of most periodontal diseases are
relatively simple and very effective, providing
lifetime benefits.
4
6. • The clinical and radiographic images of gingiva and
periodontium in children and adolescent differ
from those seen in adults, owing to the significant
changes taking place during growth and
development.
• The periodontium during childhood and puberty is
in constant state of change owing to the
exfoliation and eruption of teeth.
6
7. • This makes a general description of the normal
periodontium difficult because it varies with age
of the patient. (Baer and Benjamin, 1974)

13. ERUPTION GINGIVITIS
A transitory type of
gingivitis is often
observed in young
children when the
primary teeth are
erupting.
Often localized and
associated with difficult
eruption, subsides after
the teeth emerge into
the oral cavity.
13
15. The greatest increase in the incidence of
gingivitis in children is often seen in the 6- to 7-
year age group when the permanent teeth begin
to erupt.
This inflammation is most commonly associated
with the eruption of the first and second
permanent molars, and the condition can be
painful and can develop into a pericoronitis or a
pericoronal abscess.
15
16. This increase in gingivitis apparently occurs
because the gingival margin receives no
protection from the coronal contour of the
tooth during the early stage of active
eruption, where Food debris, materia alba,
and bacterial plaque often collect around and
beneath the free tissue, partially cover the
crown of the erupting tooth, and cause the
development of an inflammatory process.
Cause
16
17. TREATMENT
Mild eruption
gingivitis
requires no
treatment other
than improved
oral hygiene.
Painful
pericoronitis
may be helped
when the area is
irrigated with a
counterirritant,
such as peroxyl.
Pericoronitis
accompanied by
swelling and lymph
node involvement
should be treated
with antibiotic
therapy.
17
18. DENTAL PLAQUE INDUCED
GINGIVITIS
The degree of dental
cleanliness and the condition of
the gingival tissues in children
are related.
Adequate mouth hygiene and
cleanliness of the teeth are
related to frequency of
brushing and the thoroughness
with which bacterial plaque is
removed from the teeth
18
19. Gingivitis is generally less severe in children than
in adults with similar plaque levels.
MATSSON performed a 21-day experimental
gingivitis study comparing 6 children, aged 4 to 5
years, with 6 dental students, aged 23 to 29
years. They found that the children developed
gingivitis less readily than the adults.
19
20. Gingivitis associated with poor oral hygiene is
usually classified as:
Early (slight).
Moderate.
Advanced.
The importance of a good standard of oral
cleanliness in reducing gingivitis and, ideally,
preventing the progression of the disease in
later life.
20
21. Treatment
Brushing and
bacterial plaque is
removed from the
teeth.
Early gingivitis is
quickly reversible
and can be
treated with
adequate mouth
hygiene and
cleanliness of the
teeth.
Favorable
occlusion and the
chewing of coarse,
detergent-type
foods, such as raw
carrots, celery,
and apples, have a
beneficial effect
on oral
cleanliness
Healthy gingival

21
23. HERPES SIMPLEX VIRUS INFECTION
Herpes virus causes one of the most widespread
viral infections.
The primary infection usually occurs in a child
younger than 6 years of age who has had no
contact with the type 1 herpes simplex virus
(HSV-1) and who therefore has no neutralizing
antibodies.
It is believed that 99% of all primary infections
are of the subclinical type.
The infection may also occur in susceptible adults
who have not had a primary infection
23
24. The primary infection may be manifested by acute
symptoms (acute herpetic gingivostomatitis). which
runs a course of 10 to 14 days.
The active symptoms of the acute disease can occur
in children with clean mouths and healthy oral tissues.
May be characterized by only one or two mild sores on
the oral mucous membranes, which may be of little
concern to the child or may go unnoticed by the
parents.
24
26. The symptoms of the disease develop
suddenly and include :
Fiery red gingival tissues.
Malaise.
Irritability.
Headache.
And pain associated with the intake of
food and liquids of acid content.
26
27. Characteristic oral finding in the
acute primary disease
Is the presence of yellow or white liquid-filled vesicles.
In a few days the vesicles rupture and form painful ulcers 1 to 3 mm in
diameter .
covered with a whitish gray membrane and have a circumscribed area of
inflammation.
The ulcers may be observed on any area of the mucous membrane, including
buccal mucosa,tongue, lips, hard and soft palate, and the tonsillar areas.
Large ulcerated lesions may occasionally be observed on the palate or
gingival tissues or in the region of the mucobuccal fold.
This distribution makes the differential diagnosis more difficult.
27
28. Treatment
Specific antiviral medication as well as provision for the relief of the acute
symptoms .
The application of a mild topical anesthetic, such as dyclonine hydrochloride
(0.5%) (dyclone), before mealtime temporarily relieves the pain .
Allows the child to take in soft food..
Because fruit juices are usually irritating to the ulcerated area, ingestion of a
vitamin supplement during the course of the disease is indicated.
Bed rest .
Isolation from other children .
28
29. Recurrent Herpes Labialis (RHL)
After the initial primary attack during early
childhood, the herpes simplex virus becomes
inactive and resides in sensory nerve ganglia.
The virus often reappears later as the familiar
cold sore or fever blister, usually on the outside
of the lips .
Approximately 5% of recurrences are intraoral.
29
31. The recurrence of the disease has
often been related to:
Emotional stress .
Lowered tissue resistance resulting from various types
of trauma.
Excessive exposure to sunlight. Use of sun screen can
prevent sun-induced recurrences.
Lesions on the lip may also appear after dental
treatment and may be related to irritation from
rubber dam material or even routine daily procedures.
31
32. TREATMENT
Systemic antiviral medications daily dosages are the same as those
for the primary infection, but the course of treatment is usually 5
days instead of 10.
Food and drug administration (FDA) in children 12 years and older is
valacyclovir 2 g, initially and 2 g 12 hours later.
Topical antiviral agent, penciclovir cream may be applied to perioral
lesions but should not be applied to intraoral lesions every 2 hours
while awake for 4 days, and it is approved for use in children 12
years of age and older.
Topical 5% acyclovir cream may be prescribed for use five times
daily for 4 days in children 12 years of age and older are frequently
exposed to HSV-1
32
33. RECURRENT APHTHOUS ULCER
(CANKER SORE)
Definition :
It is a painful ulceration
on the unattached
mucous membrane that
occurs in school-aged
children and adults.
Also referred to as
Recurrent aphthous
Stomatitis (RAS)
33
34. The peak age is between 10 and 19 years of age.
Characterized by :
Recurrent ulcerations on the moist mucous
membranes of the mouth, in which both
discrete and confluent lesions form rapidly in
certain sites and feature .
Round to oval crateriform base, raised
reddened margins, and pain.
34
35. Etological factors
The cause of RAU is unknown . But it is possible that
the lesions are caused by :
Local and systemic conditions & gastrointestinal
disorders.
Genetic predisposition.
Immunologic and infectious microbial factors.
Delayed hypersensitivity to the L form of
streptococcus sanguis,
Autoimmune reaction of the oral epithelium.
35
36. Local factors include trauma, allergy to toothpaste
constituents (sodium lauryl sulfate), and salivary
gland dysfunction Nutritional deficiencies are
found in 20% of persons with aphthous ulcers.
The clinically detectable deficiencies include
deficiencies of iron, vitamin B12, and folic acid.
Stress
Ship et al also suggested herpes simplex virus,
human herpes virus type 6, cytomegalovirus,
Epstein-Barr virus, and varicella-zoster virus as
possible causes of RAS.
36
37. Treatment
Lesions persist for 4 to 12 days and heal uneventfully,
leaving scars only rarely and only in cases of unusually
large lesions .
Current treatment is focused on:
1) Promoting ulcer healing,
2) Reducing ulcer duration and patient pain,
3) Maintaining the patient’s nutritional intake,
4) And preventing or reducing the frequency of
recurrence of the disease.
37
38. • Analgesic medicines and/or systemic immuno-
modulating and immunosuppression agents .
Ex : topical corticosteroid (e.G., 0.5% fl uocinonide,
0.025% triamcinolone, 0.5% clobetasol) is applied to
the area with a mucosal adherent (e.g., Isobutyl
cyanoacrylate, orabase) before meals and before
sleeping may also be helpful or four times daily
38
39. ACUTE NECROTIZING ULCERATIVE
GINGIVITIS (VINCENT INFECTION)
Rare among preschool
children .
occurs occasionally in
children 6 to 12 years
old, and is common in
young adults.
39
40. ANUG can be easily diagnosed because of the
involvement of the interproximal papillae and the
presence of a pseudomembranous necrotic covering
of the marginal tissue
The clinical manifestations of the disease include:
Inflamed, painful, bleeding gingival tissue,
Poor appetite,
Temperature as high as 40°C (104°F),
General malaise,
And a fetid odor
40
41. Treatment :
The disease responds dramatically within 24 to 48 hours
to :
1) subgingival curettage,
2) débridement,
3) use of mild oxidizing solutions.
4) If the gingival tissues are acutely and extensively
inflamed when the patient is first seen, antibiotic
therapy is indicated.
5) Improved oral hygiene,
6) the use of mild oxidizing mouth rinses after each
meal, and twice daily rinsing with chlorhexidine will aid
in overcoming the infection. 41
43. ACUTE CANDIDIASIS (THRUSH,
CANDIDOSIS,MONILIASIS)
The lesions of the oral disease appear as raised,
furry, white patches, which can be removed easily to
produce a bleeding underlying surface
Neonatal candidiasis, contracted during passage
through the vagina and erupting clinically during the
first 2 weeks of life, is a common occurrence. This
infection is also common in immunosuppressed
Patients.
sometimes develop thrush after local antibiotic
therapy .
43
45. Treatment :
Antifungal antibiotics control thrush.
For infants and very young children, a suspension of
1 mL (100,000 U) of nystatin (Mycostatin) may be
dropped into the mouth for local action four times a
day. The drug is nonirritating and nontoxic.
Clotrimazole suspension (10 mg/mL), 1 to 2 mL
applied to affected areas four times daily, is an
effective antifungal medication.
Systemic fluconazole suspension (10 mg/mL) is safe
to use in infants at a total dosage of 6 mg/kg or less
per day.

46. CHRONIC NONSPECIFIC
GINGIVITIS
A type of gingivitis commonly seen during the pre-
teenage and teenage years .
May be localized to the anterior region, or it may
be more generalized.
Although the condition is rarely painful, it may
persist for long periods without much improvement
46
48. CHARACTERIZED BY :
The fiery red gingival lesion is not accompanied by
enlarged interdental labial papillae or closely
associated with local irritants.
The gingivitis showed little improvement after a
prophylactic treatment.
The age of the patients involved and the prevalence
of the disease in girls suggested a hormonal
imbalance as a possible factor.
Histologic examination of tissue sections and the use
of special stains ruled out a bacterial infection.
48
49. Treatment :
An improved dietary intake of vitamins and
the use of multiple-vitamin supplements will
improve the gingival condition in many
children.
Improved oral hygiene.
49
50. Gingival Diseases Modified By
Systemic Factors
• Gingival Diseases Associated With The
Endocrine System
• Gingival Lesions of Genetic Origin.
• Drugs Induced Gingival Overgrowth.
• Ascorbic Acid Deficiency Gingivitis
(Scorbutic Gingivitis)
50
51. GINGIVAL DISEASES ASSOCIATED
WITH THE ENDOCRINE SYSTEM
Puberty gingivitis is a distinctive type of gingivitis
that occasionally develops in children in the
prepubertal and pubertal period.
The gingival enlargement was marginal in distribution
and, in the presence of local irritants, was
characterized by prominent bulbous inter proximal
papillae far greater than gingival enlargements
51
53. Treatment
Improved oral hygiene,
Removal of all local irritants,
Restoration of carious teeth,
Dietary changes necessary to ensure an adequate
nutritional status.
Oral administration of 500 mg of ascorbic acid.
However, the improvement did not occur until the
vitamin had been taken for approximately 4 weeks.
53
54. • Severe cases of
hyperplastic gingivitis
that do not respond to
local or systemic therapy
should be treated by
gingivoplasty.
• Recurrence of any
hyperplastic tissue will be
minimal if adequate oral
hygiene is maintained.
54
55. GINGIVAL LESIONS OF GENETIC
ORIGIN
Hereditary gingival fibromatosis
(HGF) .
This rare type of gingivitis has
been referred to as
elephantiasis gingivae or
hereditary hyperplasia of the
gums
Is characterized by a slow,
progressive, benign enlargement
of the gingivae.
Has an autosomal dominant
mode of inheritance.
55
56. The gingival tissues appear normal at birth but
begin to enlarge with the eruption of the primary
Teeth.
the gingival tissues usually continue to enlarge with
eruption of the permanent teeth until the tissues
essentially cover the clinical crowns of the teeth .
The dense fibrous tissue often causes displacement
of the teeth and malocclusion.
The condition is not painful until the tissue enlarges
to the extent that it partially covers the occlusal
surface of the molars and becomes traumatized
during mastication
56
57. Treatment :
Surgical removal of the hyperplastic tissue
achieves a more favorable oral and facial
appearance.
Hyperplasia can recur within a few months after
the surgical procedure and can return to the
original condition within a few years.
importance of excellent plaque control should be
stressed to the patient because this delays the
recurrence of the gingival overgrowth.
57
58. Drugs -INDUCED GINGIVAL
OVERGROWTH
Many drugs that have been reported to induce gingival
overgrowth in some patients include:
1) Phenytoin (dilantin, or diphenylhydantoin)
anticonvulsant.
2) Cyclosporin.
3) Calcium channel blockers
4) Valproic acid.
5) Phenobarbital
58
59. PHENYTOIN-INDUCED
GINGIVAL OVERGROWTH
Phenytoin (dilantin, or diphenylhydantoin), a major
anticonvulsant agent used in the treatment of epilepsy.
Side effects of varying degrees of gingival hyperplasia
first described by kimball in 1939.
Phenytoin-induced gingival overgrowth.
An increase in the number of fibroblasts in patients
receiving dilantin.
59
61. , Begins to appear as :
Early as 2 to 3 weeks after initiation of phenytoin therapy
and peaks at 18 to 24 months.
The initial clinical appearance is :
Painless enlargement of the interproximal gingiva.
The buccal and anterior segments are more often
affected than the lingual and posterior segments.
The affected areas are isolated at first but can become
more generalized later.
61
62. Unless secondary infection or infl ammation is present, the gingiva
appears pink and firm and does not bleed easily on probing.
As the interdental lobulations grow, clefting becomes apparent at the
midline of the tooth.
With time the lobulations coalesce at the midline, forming pseudopockets
and covering more of the crown of the tooth.
The epithelial attachment level usually remains constant.
In some cases, the entire occlusal surface of the teeth becomes
covered.
These lesions may remain purely fibrotic in nature or may be combined
with a noticeable inflammatory component
62
63. ASCORBIC ACID DEFICIENCY
GINGIVITIS
(SCORBUTIC GINGIVITIS)
Scorbutic gingivitis is associated
with vitamin C deficiency and
differs from the type of
gingivitis related to poor oral
hygiene.
The involvement is usually limited
to the marginal tissues and
papillae.
The child with scorbutic
gingivitis may complain of severe
pain, and spontaneous hemorrhage
is evident.
63
64. Severe clinical scorbutic gingivitis is rare in children.
It may occur in children allergic to fruit juices.
Inflammation and enlargement of the marginal gingival
tissue and papillae in the absence of local predisposing
factors are possible evidence of scorbutic gingivitis.
Treatment :
Daily administration of 250 to 500 mg of ascorbic acid.
Older children and adults may require 1 g of vitamin C
for 2 weeks to speed recovery.
64
65. CONCLUSION
Gingivitis is a reversible disease. Therapy is aimed
primarily at reduction of etiologic factors to reduce or
eliminate inflammation, thereby allowing gingival tissues
to heal.
Complete dental care, improved oral hygiene, and
supplementation with vitamin C and other water-soluble
vitamins will greatly improve the gingival condition.
As with all disorders affecting periodontal tissues,
maintaining excellent oral hygiene is the primary key to
successful therapy.
