A condition affecting the blood's ability to clot and stop bleeding.
In disseminated intravascular coagulation, abnormal clumps of thickened blood (clots) form inside blood vessels. These abnormal clots use up the blood's clotting factors, which can lead to massive bleeding in other places. Causes include inflammation, infection and cancer.
Disseminated intravascular coagulation (DIC) is a condition in which blood clots form throughout the body, blocking small blood vessels. Symptoms may include chest pain, shortness of breath, leg pain, problems speaking, or problems moving parts of the body.

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.

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.

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).

4. • The spleen is a small organ that sits inside the left rib cage,
just above the stomach. In adults, the spleen is about the size
of an avocado.
• The spleen is part of the immune system
FUNCTIONS OF THE SPLEEN INCLUDE:
• This largest lymphatic organ
• Stores blood.
• Filters blood by removing cellular waste and getting rid of old
or damaged blood cells.
• Makes white blood cells and antibodies that help fight
infection.
• Maintains the levels of fluid in the body.
• Produces antibodies that protects against infection.
5. SPLENIC ABSCESS
• splenic abscess: these are localized collections of
necrotic inflammatory tissue caused by bacterial,
parasitic or fungal agents.
• Infection reach the spleen through blood /lymph as a
complication from abdominal infections like appendicitis
or peritonitis
6. Signs and symptoms
• Fever due to presence of infection
• Tenderness
• Enlargement of the spleen-visibly enlarged or felt
on palpation
7. investigations
• Blood culture for sensitivity
• FBC will reveal raised leukocytes
• Ultrasound scan will show inflammation
• CT Scan / MRI will show the pus filled pouches in the
spleen.
8. TREATMENT
• High dose antibiotics ie ceftriaxone 1g BD for 10-14
days
• Splenic drainage of pus
• Splenectomy-removal of the spleen in cases where the
abscesses are diffuse and not responding to treatment.
11. Signs and symptoms
An enlarged spleen typically doesn’t cause any symptoms, but
at times patients can present with:
• Pain or fullness in the left upper quadrant that can spread to
the shoulder
• A feeling of fullness without eating anything as the spleen is
pressing on the stomach
• Frequent infections
• Bleeding easily
12. TYPES OF SPLEENOMEGALY
• Reactive splenomegaly: occurs in acute and chronic
inflammatory conditions probably caused by phagocytosis of
blood or bacteria and the release of chemicals form the
inflammatory processes. Ie in malaria, rheumatoid arthritis.
• Congestive splenomegaly: results from chronic congestion
of the spleen from conditions such as; C.C.F ,heart failure
and portal hypertension.
• Other causes are: Hyperplasic disorders caused by
haemolytic anaemia ,Cysts and tumours: these maybe rare
but they do occur e.g. leukaemia as well as lymphoma.
13. diagnosis
• Physical examination will reveal an enlarged spleen, aneamia
• FBC will reveal raised WBC, low RBCs and platelets.
• Check the clotting factors
• Ultrasound scan will reveal an enlarged spleen
• MRI/CT Scan
• Biopsy of the spleen is not commonly done due to high risk
of bleeding
14. TREATMENT
• Treat according to cause.
• High dose antibiotic if the enlargement is due to bacterial involvement
• Splenectomy-removal of the spleen
• After removal, put patient on regular checks for platelet count and
clotting factors
• Patient is given vaccinations against pneumococcal , meningococcal
and heamophilus influenza as these can prove to be deadly if
contracted.
• Patient is put on penicillin's for prevention of infection and anti
malarial prophylaxis like Malo-prim to prevent malaria
15. • Following splenectomy, the patient is at high risk
of developing Overwhelming Post Splenectomy
Infection. This is usually fatal. It is characterized
by either meningitis or sepsis.
• It can be prevented by vaccinations and
prophylaxis and telling patient to prevent
infections by putting on a mask and
handwashing/wearing gloves.
18. RAPTURED SPLEEN
• A raptured spleen is a surgical emergency that occurs
to spleen bursts
This can be caused:
• Sudden blow to the spleen
• Accidental trauma during surgery
• In spleenomegally when the spleen becomes too
enlarged
• In splenic sequestration: this is when blood pulls into
the spleen and cant escape.
19.
20. Signs and symptoms
• Pain in the left upper abdomen
• Tenderness on touch
• Confusion, lightheadedness or dizziness
• Signs of shock ie cold clammy skin, low bp, fast
thready pulse.
22. MANAGEMENT OF A PATIENT WITH
RAPTURED SPLEEN
• Raptured spleen is an emergency, if patient is not handled well, they may
die.
• Upon receiving a suspected raptured spleen patient, canulate patient with
large bore canular(grey) and commence Ringers lactate which is a blood
expander.
• Inform the surgeon.
• Vitals should be done quarter hourly to rule out hypotension and shock.
Monitor patient for signs of shock.
• Do ultra-sound scan as soon as possible. Do other investigations like
grouping and crossmatching. Full blood count and label as urgent.
• Catheterize and prepare patient for theater(explain procedure, consent,
tagging and NG tube insertion)
24. DEFINITION
A splenectomy is the total or partial surgical removal of
the spleen, an organ that is part of the lymphatic
system.
25. FUNCTIONS OF THE SPLEEN
1. Phagocytosis: destroys old and abnormal RBCs,
parasites, cellular debris and other cells
2. Storage of blood: a reservoir of about 350ml of
blood, important during haemorrhage
3. Immune response: contain T- and B- lymphocyte,
which are activated by presence of antigens, e.g.
infection
4. Erythropoiesis: major hematopoietic functions until
5th month of gestation when the bone marrow
assumes its function.
26. INDICATIONS FOR SPLENECTOMY
1. Trauma of the spleen
• The spleen is the most commonly injured solid organ in the
abdomen following blunt trauma,
• The spleen can be ruptured by blunt as well as penetrating
injuries to the chest or abdomen.
• E.g. Car accidents are the most common cause of blunt
traumatic injury to the spleen
• This causes massive bleeding intra-abdominally and it is an
emergency due to shock.
27. INDICATIONS FOR SPLENECTOMY cont’d
2. Primary cancers of the spleen ( malignancy)
• Metastatic tumors of any kind, e.g.: cancer of the breast,
lung, melanoma and virtually any primary malignancy may
metastasize to the spleen.
• Evidence of metastasis to the spleen detected early
requires surgical removal of the spleen.
28. Indications Cont’d
3. Hereditary spherocytosis
• The absence of a specific protein(spectrin),in the red blood cell
membrane leads to the formation of relatively fragile
cells(spherocytes) that are easily damaged when they pass
through the spleen.
• The cell destruction does not occur elsewhere in the body and
ends when the spleen is removed.
29. Indications cont’d
4. Immune (idiopathic) thrombocytopenic purpura (ITP).
• ITP is a disease in which platelets are destroyed by antibodies in the
body's immune system.
30. Indications cont’d
5. AUTOIMMUNE HEMOLYTIC DISORDERS.
• The red blood cells are destroyed by antibodies produced by the
patient's own body (autoantibodies)
• E.g. as in patients with sickle cell disease with
acute Splenic sequestration crisis (rapid enlargement of spleen, anemia,
pain)
31. Indications cont’d
Non-Hodgkin's Lymphoma
• This is a cancer of the lymph nodes or organs
7. SPLENIC ABSCESSES
• Splenic abscess is an uncommon and potentially fatal
illness.
• 8. SPLENIC CYSTS
32. MANAGEMENT
DIAGNOSIS
• The most important part of a medical assessment in disorders
of the spleen is the measurement of splenomegaly
• Ultrasound scan
• Computed Tomography (CT) scan
• The rate of platelet or red blood cell destruction by the spleen
can also be measured by tagging blood cells with radioactive
chromium or platelets with radioactive indium
33. PREOPERATIVE CARE FOR A SPLENECTOMY
• Admit client a day or 2 before operation
• Offer psychological care on importance of the
operation
• Collect blood for grouping and x- match in
preparation for transfusion of fresh whole blood/
fresh platelets where indicated.
• Obtain consent form for legal purposes
34. PREOP. CARE CONT’D
• Give vitamin K 2mg intravenously to prevent haemorrhage
during and after splenectomy as prescribed by the surgeon
• Give Haemophilus influenza B (HIB),
• Pneumococcal (Pneumovax or Pnu-Imune 23 )
• and Meningococcal (Menomune-A/C/Y/W-135 ) vaccines to
children whose immunization status is unclear to prevent
infection with streptococcal pneumonia, flu and meningitis
infections post operatively, ie, after splenectomy.
35. POST- OPERATIVE CARE
• In addition to the general post operative care, the follow
is also specific to splenectomy:
• Maintain patent airway to prevent aspiration
• Give fresh whole blood or fresh platelets to prevent post
operative haemorrhage as prescribed by the surgeon
• Maintain an intake and output chart to prevent fluid
overload( fluids are given with caution to avoid
haemodilution)
36. POST- OPERATIVE CARE CONT’D
• Give Pethidine 10mg -100mg IM 8 hrly as prescribed to
relieve post operative pain
• Give prescribed antibiotics such as X-pen (infant under 1
year 300 mg; child 1–9 years 600 mg, 10 years and over as
for adult 2.4 mega) 6 hrly IV for 7 days.
• Give malaria prophylaxis to prevent malaria infection with
Fansidar
• Give a splenectomy card/ medicalert bracelet to alert
health care providers in case of massive infection
37. COMPLICATIONS OF SPLENECTOMY
• Pain
• Bleeding
• Developing a hernia in the scar
• Post-splenectomy sepsis
• Pancreatitis: occasionally follows splenectomy. This is due to handling and
bruising of the tail of the pancreas during immobilization of the pancreas.
• Transient increase in the platelet and white cell count: these predispose to the
risk of venous thrombosis. Low dose heparin is advised in all patients
undergoing splenectomy.
• . Loss of lymphoid tissue: reduces immune activity and impairs the response to
bacteremia.
