Occupational respiratory diseases caused by dust (pneumoconiosis) Silica, Asbestos, talc, coal

Silicosis A fibrotic lung disease produced by inhalation of dust containing Silicon dioxide.

Etiology It is present in sand, sand stone & granite. In these occupations: Mines, Porcelain manufacture & Glass industry.

Predisposing factors: 1. Duration of exposure (long period 5 — 10 years). 2. Size: Smaller dust particles are more injurious. 3. Concentration: the higher the conc. of dust  the more injurious. 4. The presence of free silica in the dust. 5. Personal susceptibility.

Pathogenesis Silica particles are ingested by alveolar macrophages  carry them to lung tissue  macrophages disintegrate  stimulate fibroblast function & collagen formation, - Damaged macrophages attract others that ingest released silica particles

Pathology Silicosis  nodular fibrosis, layers of collagen (ONION RING APPEARANCE) Clinical picture DYSNEA Complications: Tuberculosis. Corpulmonale as a result of pulmonary hypertension, chronic bronchitis & emphysema

Diagnosis: 1. History of exposure 2. Radiological examination: Nodular shadow 3. Pulmonary function testing FVC, FEV1 below normal levels.

Hypertension The elevation of arterial blood pressure over 140 / 90 in adults

Risk factors a) Host factors 1. Genetic - Heredity interacting with the environmental role  not all hypertensive patients have diseased offspring. - So children of hypertensive parents should be screened & advised to avoid environmental factors that aggravate hypertension (e.g. smoking, physical inactivity, and excess sodium) 2. Low birth weight Low birth weight due to fetal under- nutrition followed by  ↑ B.P. later in life 3. The role of sodium salt in essential hypertension - ↑ sodium intake in diet  ↑ B.P… 4. Obesity: HTN is common among obese individuals  ↑ risk of ischemic heart disease 5. Physical inactivity: Physical fitness  prevent HTN 6. Alcohol intake 7. Smoke: Cigarette smoking  ↑ B.P., through nicotine  release of nor-epinephrin. 8. Hyperuricemia: Present in 25 - 50 % of individuals with untreated 1ry HTN. 9. Ethnic group: Adult blacks have HTN  to higher rises of morbidity and mortality. 10. Sex: Before menopause, HTN is less common in women than in men, but after that HTN is equally common & dangerous in elderly males & females. 11. Age: At old age  more HTN cases & age related atherosclerosis. 12. Diabetes mellitus: HTN & diabetes coexist commonly

Cancer Descriptive epidemiology Cancers arise from undifferentiated stem that are capable of mitotic division & differentiation. 1. Age: most cancers develop in the 6th, 7th, 8th decades of life. 2. Sex: cancers of non-sexual sites occur in men than women, except in gallbladder & bile ducts. 3. Race & Geography: Cancers varies among racial groups in the same country.

This variation is due to: - Cultural patterns

- genetic difference among the races - social behavior

- economic status.

4. Time Trends: - The high ↑ in rates of lung cancer is largely due to cigarette smoking. - Decline in rates of stomach cancer is unknown but may be related to dietary habits, (consumption of less preserved & more fresher foods) - Decline in mortality from uterine cancer is probably due to combination of 3 factors: 1. ↓ number of women who still have a uterus 2. ↑ cytological screening

3. Decline in the incidence of new cases

Etiology & 1ry prevention Initiators - Agents cause the genetic damage to the stem or intermediate cells. - Ionizing radiation, chemicals & certain viruses Community Oct. Med.

0105068372 Initiators  rearrangements in DNA  ↑ expression of normal genes (ONCOGENES) Promotors  ↑ rate of growth & number of stem & intermediate cells (targets for initiators)  to enhance growth of tumor cells Estrogens  ↑ proliferation of endometrium  endometrial cancer

Risk factors 1. Tobacco - Compared to non-smokers, risk in the average cigarette smoker is - ↑ 10 fold  lung cancer,

- ↑ 8 folds  laryngeal cancer

- ↑ 4 folds  mouth & pharynx - ↑ 3 folds  esophageal cancer - ↑ 2 folds  bladder, renal pelvis, ureter & pancreas - Risk is increased by about 30% in non-smoking members with a resident smoker.

2. Alcohol - Risk of neoplasms is associated with alcohol consumption. - Hepatocellular carcinomas develop at ↑ rate in alcoholics with macro-nodular cirrhosis. - ↑ Risk for carcinomas of mouth (buccal cavity & pharynx) & esophagus

3. Industrial exposures Specific exposure

Site or tumor type

Arsenic & arsenic compounds

Lung, skin

8. Infectious agents: EBV  nasopharvnea1 carcinomas HBV  Hepatocellular carcinoma (Hepatoma) HBV viral DNA  cervical cancers Human immunodeficiency virus (HIV)  AIDS An RNA virus  Kaposi sarcoma & non Hodgkin’s lymphomas

9. Nutrition Aflatoxins produced by fungi  liver cancers it some parts of the world. Food additives May be carcinogenic, the evidence is weak - ↑ artificial sweeteners  ↑ risk of bladder cancer - ↑ fat diet  cancers of colon, breast & prostate Over-nutrition  obesity  associated with endometrial & postmenopausal breast cancers N.B. - Fibers in diet ↑ bulk of bowel contents & ↓ intraluminal carcinogens by ↓ contact of colonic mucosa with carcinogens. - ↑ Fresh fruits Diets & raw vegetables  ↓ carcinomas risks in GIT & RT.

10. Reproductive factors Single women (specifically nulliparous)  at ↑ risk of ovary, endometrium & breast cancers.

11. Genetic factors Some individuals exposed to a carcinogen  develop cancer & others with identical exposure do not, Due to differences in genetic susceptibility to carcinogens - Carcinomas of breast & prostate. - Malignant melanomas occur in light skinned individuals with blond or red hair & blue eyes. - Stomach cancers occur more in persons with blood gp A.

Care of the Newborn - Neonatal care contributes to maternal health, reproductive health & safe motherhood. - Neonatal care aims at: health promotion of newborn, prevention of morbidity & mortality.

Outcome of Pregnancy: 1. Favorable: delivery of a healthy live born. 2. Unfavorable i.e. dead baby (called pregnancy wastage), It is of two types: • Lethal i.e. abortion, miscarriage, stillbirth, neonatal death & postneonatal deaths • Sublethal: e.g. congenital anomalies, mental retardation, cerebral palsy, Also prematurity.

Factors affecting the outcome of pregnancy 1. Age of mother, risk is below [6 and above 40 years 2. Parity risk is lowest with parity 1-4 3. Pregnancy spacing, most suitable 2-3 years 4. State of maternal health including: - Body built (height) - Syphilis and malaria - Drugs & radiations

- Nutritional status - Smoking - Outcome of previous pregnancy.

Maternal mortality Maternal mortality: a biostatistical index which monitors the safety of the reproductive process through which mothers in the reproductive age might pass through. The interaction between the maternal fitness & environmental factors would determine the process of maternity and its outcome part of which is the maternal survival - Maternal mortality is death of women during performing their maternity function at pregnancy, delivery or puerperium. Maternal Mortality is one of the main indicators of the health status & welfare of a community.

Ecology of maternal mortality Agent - Failure of adaptation to pregnancy, delivery or puerperium. - Occurs when the stress of the maternity process exceeds the vital reserve of the mother.

Host - Mothers who are intolerant to maternity stress might be due to: 1. Limited vital reserve due to constitutional factors 2. Incomplete recovery of their vital reserve due to previous maternity or other stressing factor (recovery needs 2 years at least). 3. Morbid condition whether limiting her vital reserve to the maternity process. • Endocrine Balance: Pregnancy & delivery are the stresses to which mothers are exposed. Community Oct. Med.

16

2008

0105068372 • Nutrition: Proper nutrition makes mother more tolerant to stress of maternity process. • Age: Excess of deaths among older women & excess among women younger than 20. - Risk of maternal death was higher in mothers aged more than 40 years • Parity: Maternal mortality is high among primipara then it drops & reincreases again among those who had five or more children.

Time of maternal death The 2000 NMMS found that most maternal deaths took place during delivery or postpartum: Maternal deaths in 2000 were more likely to occur during delivery (49% compared to 39% in 1992-93) and less likely to occur during the postpartum period (27% compared to 35% in 1992-93).

Causes of maternal mortality” - There are three groups of causes which lead to maternal mortality”

1. Direct causes These are the causes due to complications of pregnancy, delivery & puerperium & trials to manage the case during this maternity process including abortion. The three leading causes of maternal mortality in Egypt: haemorrhage, toxemia & sepsis. - Hemorrhage before & after delivery (43%of maternal death), with most hemorrhage deaths due to postpartum hemorrhage. - Other direct causes: hypertensive disease of pregnancy (22%), sepsis (8%), ruptured uterus (8%), cesarean section (7%) & obstructed labor (5%).

2. Indirect causes - These are causes due to aggravation of pre-existing conditions as rheumatic heart during pregnancy, delivery & purperium. - Cardiac disease: the indirect cause of maternal deaths (13%) - Anemia was the second most important indirect cause of maternal death (11 %).

3. Causes not related to the mortality process: as traffic accidents

Interventions to reduce maternal mortality 1. Setting up maternal mortality committees on national, regional & local levels & keeping them operative. 2. Improving the system for the registration & capture of information of all heath actions relating to pregnancy, delivery & family planning. 3. Ensuring the existence of a national system for the epidemiologic surveillance of mortality of women of reproductive age that provides data of sufficient quantity & quality to determine the real scope of the problem, the structure of its causes & the social determinants of maternal mortality. 4. Incorporate the investigation of maternal mortality within the routine work of personnel working in MCH Units. 5. Formulate maternal mortality panel at district level so as to be able to thoroughly revise the causes of conditions of every maternal health. 6. Training Obs/Gynophysician at hospitals on accurate diagnosis of direct & underlying causes of maternal deaths. 7. Establishment of system for accurate diagnosis of maternal deaths in death certificate in the health office. 8. Set monthly audits to discuss any case of death due to pregnancy & labor to determine the cause of death 9. Community education and mobilization is essential so that women & their families learn about the need for special care during pregnancy & childbirth.

Community education must address traditional beliefs about pregnancy-related complications that are often blamed on a woman’s behavior, fate, evil influences & other factors beyond the reach of the health system. 11. Dialogue among communities, policy-makers, and health system staff is essential to identify ways of overcoming barriers to women seeking maternal care.

Child Health Care - MCH centers are responsible for care of under 5 years children (from birth to school age), & include infants & preschool children.

Objectives of the child health care program 1. Monitoring of growth & development of children. 2. Implementation of the program of compulsory (obligatory) vaccination to prevent diseases. 3. Treatment of common diseases & early detection of critical cases to be referred to specialized clinics. 4. Control of infectious diseases. 5. Minimization of under 5 years mortality. 6. Prevention of diarrhoeal diseases as well as respiratory tract infection. 7. Health education. 8. Rehabilitation.

I. Infectious diseases - Infection is a health problem in developing countries. - It may be congenital or acquired.

(a) Congenital infection It is in utero infection (vertical infection) - Transmitted from the mother to her - embryo (during the 1st trimester) before formation of placenta - fetus (trans-placental infection) N.B. Congenital infection lead to unfavorable outcome of pregnancy which is lethal (abortion, still birth) or sublethal (congenital anomalies or congenital diseases e.g. Syphilis, Rubella syndrome, , AIDS) Forms of congenital infection: Syphilis, rubella, cytomegallo inclusi5n virus, hepatitis B virus infection, AIDS, Toxoplasma gondii.

(b) Acquired infections (classification acc. to the age of the child) 1. Neonatal infections: Infections acquired during the 1st 4 weeks after birth. - These infections are acquired during the process of delivery from the birth canal of the mother or faulty practices after birth, environment has very little contribution to acquired neonatal infection. Important forms of neonatal Infections: Opthalmia neonatoruan, conjunctivitis, Otitis media, Pneumonia, Herpes simplex, Tetanus neontorum, diarrhoeal diseases of new born, AIDES, cytomegallo inclusion virus. 2. Prenatal infection: infections occur in the prenatal period (from the 28th week of intrauterine life till the 1St week neonatal period). 3. Infections occurring in infants: (Children during the 1st year of life) They are exposed to: a. Diarrhoeal diseases it was the 1st killer for infants accounting for half of deaths of infants.which before the introduction of ORT, b. Acute respiratory tract infections (Upper & lower). c. Infective conjunctivitis & infective skin diseases. 4- Infections of childhood Community Oct. Med.

20

2008

0105068372 - Many infectious diseases are endemic in the developing countries. - Susceptibility begins from the 6th month of infancy due to the fade out of maternally acquired immunity except for pertussis & T.B. in which there is no maternally acquired immunity. - Pertussis: Big molecule of immunoglobulin “M”, that can not pass through the placenta. - Tuberculosis: cell-mediated immunity. The risk of infection is aggravated by faulty breast feeding practices, malnutrition & faulty weaning practices. Infectious diseases occur in sporadic cases, epidemics or outbreaks.

Forms of infectious diseases: 1. Poliomyelitis: sporadic cases in endemic areas like Egypt (no epidemics). 2. Diarrhoea 3. Acute respiratory tract infections (ARI). 4. Measles. 5. infective conjunctivitis & skin diseases. 6. Tuberculosis: (milk borne) intestinal TB.

Prevention of infectious diseases in childhood 1. Maternal measures a) Health education of mothers & girls b) Premarital care: active immunization & treatment of any infection. c) Prenatal care: Health appraisal, active immunization by tetanus toxoid (no live vaccines during pregnancy). d) Intra-natal care: Asepsis is the rule

2. Child care measures: a) Neonatal care: 1. Aseptic cutting of the cord & slump dressing. 2. Antibiotic eye drops immediately after birth 3. Early initiation of breast feeding within half an hour after birth & establish good breast feeding practices. b) Health appraisal  for diagnosis & management of morbidity that may predispose to infection. c) Proper nutrition. d) Prevention of infection in low birth weight units, incubators & paediatric units Community Oct.

II- Parasitic diseases Some parasitic diseases are endemic in developing countries particularly in rural areas e.g. Entrobius vermicularis (most prevalent), Schistosoma (infrequent in preschool children),

Ascaris lumbercoids, giardia lamblia, Hymenolepis nane, Entamoeba histolytica, Ancylostorna, Malaria Impact of parasitic diseases on child health: a) Impairment in physical & mental development. b) Predispose to malnutrition.

IIIMalnutrition About 50% -60% of under 5 years mortality is at attributed to or associated with malnutrition. Important forms of malnutrition: Iron deficiency anaemia, Protein-energy malnutrition Rickets, Vit A deficiency, Riboflavin deficiency, I2 deficiency (endemic goiter). The government compat vit A deficiency by its adminstration to pregnant females (600.000 iu) & to infants at the 9th month l00000 iu) also, iodinization of table salt to combat iodine deficiency

IVAccidents Below-five-year children are exposed to Varity of injuries starting from birth injuries, home & road injuries.

V- Social disorders Contributing factors 1) Big family size & low percapita income. 2) Poor housing & high crowdness index 3) Low socioeconomic standards 4) Separation of parents (loss of love & security) 5) Mother’s Employment (lack of close with mother)

2008

0105068372 - It is classified according to its etiology into: a) Congenital

b) Acquired

a) Congenital handicapping Examples: Mental retardation — Microcephaly — Hydrocephalus — cleft lip or palate. Causes: 1. Genetic factor: Gene mutation & chronomosomal abrasion e.g down’s syndrome. 2. Inutero Exposure to adverse condition: a. Maternal infection acquired during pregnancy e.g. toxoplasma gondii, hepatitis B infection, syphilis, measles, mumps, rubella. b. Live vaccines administered to pregnant mothers during or shortly before (less than 3 months) pregnancy. c. Teratogenic agents (drugs, heavy metals, radiation). d. Smoking: risk factor for low birth weight & prematurely. e. Air pollution & Malnutrition of the mother may play a role: Examples i. Iodine deficiency predispose to congenital cretinism. ii. Severe protein deficiency may predispose to LBW

Prevention: Congenital disability could be prevented through premarital, preconceptional & pre- natal care. 1. Premarital care a. Premarital counseling & examination for diagnosis & treatment of sexually transmitted diseases, genetic counseling to avoid hereditary diseases. b. Vaccination in non immune couples; females are vaccinated at least 3 months before pregnancy. c. Health education for healthy life & avoid any harmful practices that may affect pregnancy. 2. Prenatal care: to ensure healthy safe intrauterine growth & development & to avoid adverse intrauterine. 3. Health education: It is a continuous process to preparation of girls to be the future mothers. It is continued till child birth. Community Oct. Med.

Quality of health care

Quality It defined as “Fitness for purpose”. Or as “conformance to specification” Or as "a degree or standard of achievement”. - The British standards Institute defines quality as the totality of feature & characteristics of a product or service that bear on its ability to satisfy stated needs. - Quality of technical care consists of: application of medical science & technology in a manner that maximizes its benefits to health without increasing its risks. - Degree of quality is, the extent to which the care provided is expected to achieve the most favorable balance of risks & benefits. - Quality of health care is a process of change or fully meeting requirements of lowest cost or more specifically full meeting the needs of consumers Quality:- Doing the right thing  Appropriate. - Doing the right thing right  Effective. - Doing the right thing for 1st time & every time  Efficient.

Family Medicine

Principles of Family Medicine 1. Continuity of care 3. Coordinated care 5. Health care in the community context.

2. Comprehensive care 4. Care of patient in the family context

1. Continuity of care

Family practice is defined as the medical specialty that provides continuity and comprehensive health care for the individual & the family.

2. Comprehensive care

Family practitioners can provide independent care for 85 90% of problems encountered in daily practice. - Comprehensive care may be synonymous with personal medicine. - Personal medicine is a process of providing broad-based health care which both physician & patient recognize that the relationship extends beyond that of provider and client. - When providing personal medicine, the physician may act as advisor, advocate, confidant or healer. Community Oct. Med.

0105068372 - The specialty of family physician including adolescent health care, sports medicine, addiction medicine and geriatrics.

3. Coordinated care

- Family physician have traditionally served as the patient’s first contact and point of entry into the health care system. - Hence, care is provided for all problems. - This physician serves as the patient’s or family’s advocate in all health-related matters, including the appropriate use of consultants and community resources. - His training and experience qualify him to practice in the several fields of medicine & surgery.

4. Health care of the patient in the family environment

Family is part of family physician and family practice is integral to their definitions.

5. Family practice

- is a people —oriented specialty physicians today choose family practice because they wish to be people doctors not doctors for organs, machines or age groups. General guidelines for family medicine 1. Provide personal care for individual & family 2. Manage acute & chronic medical problems in the community. 3. Provide anticipatory (predicted) health care using education, risk reduction, & health enhancement strategies. 4. Provide continuous health care, not limited by a specific disease 5. Provide comprehensive care of complex and sever problems. 6. Establish physician-patient relationships by using interpersonal communication skills to provide quality health care. Five Star Doctor - The concept of the “five-star doctor” is an ideal profile of a doctor possessing a mix of aptitudes to carry out the range of services that health settings must deliver to meet the requirements, quality, cost-effectiveness & equity in health. - The five sets of attributes of the “five-star doctor” are summarized as follows: - Care provider - Community leader

1. Care-provider

- Decision-maker - Manager

- Communicator

- Besides giving individual treatment “five- star Doctors” must take into account the total (physical, mental & social) needs of the patient. - They must ensure that a full range of treatment — curative, preventive will be dispensed in ways that are complementary, integrated & continuous. - And they must ensure that the treatment is of the highest quality.

2. Decision-maker

“Five-star doctors” have to take justified & efficient decisions. 28 Community Oct. Med.

2008

0105068372 - In treating a given health condition, the one that seems most appropriate in the given situation must be chosen.

3. Communicator

- The doctors of tomorrow must be excellent communicators in order to persuade individuals, families & the communities in their charge to adopt healthy lifestyles & become partner in the health effort.

4. Community leader

The needs and problems of the whole community- in a suburb or a district — must not be forgotten. By understanding the determinants of health inherent in the physical and social environment “five-star doctors” will not simply be treating individuals who seek help but will also take a positive interest in community health activities which will benefit large numbers of people.

5. Manager

- To carry out all these functions, it will be essential for “five-star doctors” to acquire managerial skills. - This will enable them to initiate exchanges of information in order to make better decisions.

Ten steps to successful breast feeding

1. Have a written breast feeding policy communicated to all health care staff 2. Train all health care staff necessary to implement the policy. 3. Inform all pregnant women about the benefits and management of breast feeding. 4. Help mothers initiate beast feeding within a half-hour of birth. 5. Show mothers how to breast feed 6. Give new born babies no food or drink other than breast milk unless medically indicated. 7. Practice rooming in-allow mothers and babies to remain together-24 hrs a day. 8. Encourage breast feeding on demand. 9. Give no artificial teats. 10. Establishment of breast feeding support groups.

What is Optimal for Breastfeedinr Practice?

1. Initiation of breastfeeding within about one hour of birth.

newborn should be offered the breast as soon after delivery as possible, preferably within one hour of birth. Nothing, nothing all except breast milk, should be given to a young infant. Early initiation stimulates breast milk production. Community Oct. Med.

0105068372 - It fosters mothers—child bonding and serves the baby’s first immunization with antibodies present in colostrums (the 1st milk).

Early initiation of breastfeeding is beneficial

For the mother • Early suckling promotes the release of a hormone that reducing the risk of mother’s haemorrhage after labor. - It helps the uterus to shrink back to normal size. - The suckling action can help expel the placenta & reduce postpartum hemorrhage. • Establishment of emotional bond between mother and child. For the child • It is important to receive the colostrums which contains antibodies that protect infant against illnesses & enhances the baby’s immune system. - Early & frequent feeding may bring in mother’s milk more quickly. - The infant will immediately benefit from the protective effect of the concentrated amounts of antibodies present in colostrum. The colostrums is like a first immunization.

2. Frequent, on-demand feeding (including night feeds)

Why young infants should suckle frequently? An infant should suckle frequentlr, both day and night. Frequent feeds are needed because: • An infant’s stomach is small and can only take in a limited quantity of breast mild at any one time. The small stomach needs to be refilled often. • Breast milk is perfectly adapted to the baby. - This means Ms more easily and quickly digested than other foods, and the infant will need to feed often. • Since the supply of breast milk is dependent on demand, frequent feeds are needed to keep up a mother ‘s milk supply. • Frequent suckling maximizes the contraceptive benefit to mothers and helps delay the return of menses. N.B. An infant should be put to the breast 8-12 times per 24 hours, for about 10-20 minutes on each breast. - Infant should sleep with the mother so that it can feed “on demand”.

Psychosexual reason reduction or elimination of the sensitive tissue of the outer genitalia, particularly the clitoris, in order to attenuate sexual desire in the female. 2. Sociological reason identification with the culture heritage, initiation of girls into womanhood. 3.
