Systemic lupus erythematosus (SLE) is the prototypic multisystem autoimmune disorder with a broad spectrum of clinical presentations encompassing almost all organs and tissues.
The extreme heterogeneity of the disease has led some investigators to propose that SLE represents a syndrome rather than a single disease.
Lupus was first recognised as a systemic disease with visceral manifestations by Moriz Kaposi (1837–1902).

Key facts
Leprosy is a chronic infectious disease caused by a type of bacteria, Mycobacterium leprae.
The disease predominantly affects the skin and peripheral nerves. Left untreated, the disease may cause progressive and permanent disabilities.
The bacteria are transmitted via droplets from the nose and mouth during close and frequent contact with untreated cases.
Leprosy is curable with multidrug therapy (MDT).
Leprosy is reported from all the six WHO Regions; the majority of annual new case detections are from South-East Asia.
Overview
Leprosy is an age-old disease and is described in the literature of ancient civilizations. It is a chronic infectious disease which is caused by a type of bacteria called Mycobacterium leprae. The disease affects the skin, the peripheral nerves, mucosa of the upper respiratory tract, and the eyes. Leprosy is curable and treatment in the early stages can prevent disability. Apart from the physical deformity, persons affected by leprosy also face stigmatization and discrimination.
Scope of the problem
Leprosy is a neglected tropical disease (NTD) which still occurs in more than 120 countries, with more than 200 000 new cases reported every year. Elimination of leprosy as a public health problem globally (defined as prevalence of less than 1 per 10 000 population) was achieved in 2000 (as per World Health Assembly resolution 44.9) and in most countries by 2010. The reduction in the number of new cases has been gradual, both globally and in the WHO regions. As per data of 2019, Brazil, India and Indonesia reported more than 10 000 new cases, while 13 other countries (Bangladesh, Democratic Republic of the Congo, Ethiopia, Madagascar, Mozambique, Myanmar, Nepal, Nigeria, Philippines, Somalia, South Sudan, Sri Lanka and the United Republic of Tanzania) each reported 1000–10 000 new cases. Forty-five countries reported 0 cases and 99 reported fewer than 1000 new cases.
Transmission
The disease is transmitted through droplets from the nose and mouth. Prolonged, close contact over months with someone with untreated leprosy is needed to catch the disease. The disease is not spread through casual contact with a person who has leprosy like shaking hands or hugging, sharing meals or sitting next to each other. Moreover, the patient stops transmitting the disease when they begin treatment.
Diagnosis
The diagnosis of leprosy is done clinically. Laboratory-based services may be required in cases that are difficult to diagnose.
The disease manifests commonly through skin lesion and peripheral nerve involvement. Leprosy is diagnosed by finding at least one of the following cardinal signs: (1) definite loss of sensation in a pale (hypopigmented) or reddish skin patch; (2) thickened or enlarged peripheral nerve, with loss of sensation and/or weakness of the muscles supplied by that nerve; (3) microscopic detection of bacilli in a slit-skin smear.
Based on the above, the cases are classified into two types for treatment
Oldest disease known to mankind
First described in ancient Indian
texts as “Kustha roga” attributed ]
to curse from God
Leper : Greek “scaly”

Rapid Sequence Intubation
RSI describes a coordinated, sequential process of preparation, sedation, and paralysis to facilitate safe, emergency tracheal intubation.
Pharmacologic sedation and paralysis are induced in rapid succession to quickly and effectively perform laryngoscopy and tracheal intubation.
The goal of RSI is to intubate patients quickly and safely using sedation and paralysis.
Mammalian bites approach to & management ;
Dog bites constitute the majority (85–90%) of animal bites followed by cats (5–10%), humans (2–3%) and rodents (2–3%). 5,6 However, any animal with teeth can bite and there are reports of bites from livestock
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
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

Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

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.

3. What is leprosy ?
• Leprosy (also known Hansen’s Disease) is an infectious disease
caused by Mycobacterium leprae which involves the skin and
peripheral nerves.
4. History of leprosy
• Leprosy was recognized in the ancient civilizations of
China, Egypt and India.
• The earliest documented account of leprosy is around
1550 B.C on Egyptian papyrus.
• Through out history, the badly affected have often been
hated by their communities and families.
5. CONT..
• Discovered by Gerhard Armauer Hansen in 1873.

6. Overview
• Key facts about
leprosy :
▫ Leprosy is a chronic
infectious disease
caused by an acid-fast,
rod-shaped bacillus,
Mycobacterium leprae.
▫ Unlike other
mycobacteria, it does
not grow in artificial
media or even in tissue
culture.
Scollard, DM et al. 2006. “The continuing challenges of leprosy.”
Clinical microbiology reviews 19, no. 2: 338-81.
7. Facts …
• M. leprae multiplies very slowly and the incubation period of
the disease is about five years. (average 3 yrs)
• Symptoms can take as long as 20 years to appear.
• Leprosy is not highly infectious.
• Leprosy is transmitted via droplets, from the nose and mouth,
during close and frequent contacts with untreated cases.
• Untreated, leprosy can cause progressive and permanent damage to
the skin, nerves, limbs and eyes.
8. Transmission
• The exact mechanism of transmission of leprosy is
not known.
• the most widely held belief is that the disease is
transmitted by contact between cases of leprosy and
healthy persons.
• & Transmission nasal discharges (droplets).
• Leprosy is known to occur at all ages ranging from
early infancy to very old age.
9. Risk Factors for Leprosy
• Close contact — Contacts of patients with leprosy have a higher risk
of developing leprosy than the general population
• People who live in the areas where leprosy is endemic
(parts of India, China, Japan, Nepal, Egypt, and other areas) and
especially those people in constant physical contact with infected
people.
• Immunity – immunocompromised individuals are more
susceptible to infection.
• Genetic influences - There is some evidence that genetic defects in
the immune system may cause certain people to be more likely to
become infected (region q25 on chromosome 6).
• Armadillo exposure — Leprosy is enzootic in the nine-banded
armadillo
10. Classification of Leprosy
• Two types of classification :
▫ Skin smear result classification. ( WHO )
▫ Clinical classification. (Ridley Jopling)
11. Classification of Leprosy
▫ Skin smear result (WHO) classification :
• 1- Paucibacillary leprosy (PB) – few Bacilli;
• Two to five skin lesions with negative skin smear results at all
sites.
• 2. Multibacillary leprosy (MB);
• Any form of leprosy in which the patient shows positive
smears at any site
14. Clinical features
1. Skin lesions, usually anaesthetic
Hypopigmented or erythematus patch / plaque .
2. Complete / partial loss of sensation.
Painless wounds or burns on the hands or feet
Paresthesias: tingling or numbness in the hands or feet
Diminished sensation or loss of sensation within skin patch(es)
3. Thickening of peripheral nerves.
4. Lumps or swelling on the earlobes or face.
5. Tender, enlarged peripheral nerves.
17. Tuberculoid leprosy: Two hypopigmented patches, hypoasthetic well
defined borders, palpable peripheral nerve and SSS negative.
18.
19.
20. Borderline lepromatous leprosy (BL/MB)
Borderline lepromatous case showing borderline tuberculoid and
"punched- out" mid borderline lesions together with papular and
nodular lesions more typical of lepromatous disease.
21. A -Claw hand due to median and ulnar
nerve damage.
B- hands showing neurotrophic
atrophy.
23. Pathogenesis
• The areas most commonly affected by leprosy
are the superficial peripheral nerves , skin
,mucous membranes of the upper respiratory
tract, eyes , and tests
• Tissue damage is caused by the degree to which
cell-mediated immunity is expressed , the extent
of bacillary spread and multiplication ,
immunologic complication and nerve damage
24. Cont…
• M leprae is an obligate intracellular acid-fast
bacillus with unique ability to enter nerves
25. Diagnosis
• Diagnosis of leprosy is most commonly based
on the clinical sign and symptoms.
• In an endemic country or area, an individual
should be regarded as having leprosy if he or
she shows ONE of the following cardinal signs :
• skin lesion consistent with leprosy and with
definite sensory loss, with or without thickened
nerves
• positive skin smears
26. Cont…
• If you have a suspicious skin sore, your doctor
will remove a small sample of the abnormal skin
and send it to a laboratory to be examined. This
is called a skin biopsy . A skin smear test may
also be done. With paucibacillary leprosy, no
bacteria will be detected. In contrast, bacteria are
expected to be found on a skin smear test from a
person with multibacillary leprosy.
27.
28. Treatment
• Common drugs
i. Dapson
ii. Refampicine
iii. Clofazimine
The combination of these three drugs
Is known as multi drug therapy (MDT)
31. complication
• disfigurement
• hair loss, particularly on the eyebrows and eyelashes
• muscle weakness
• permanent nerve damage in the arms and legs
• inability to use the hands and feet
• Nosebleeds
• iritis (inflammation of the iris of the eye), glaucoma
(an eye disease that causes damage to the optic
nerve), and blindness
• Infertility
• kidney failure
