OBJECTIVES SKIN FUNCTION APPROACH TO PATIENT WITH RASH ACUTE SKIN FAILURE COMMON CHALLENGING RASHES ALGORITHM FOR DIAGNOSING PATIENT WITH RASH SUMMARY
Skin functions The integument system of the human occupy 16% of total body WT. Protection: an anatomical barrier  Sensation Heat regulation Control of evaporation Storage and synthesis:  lipids and water
HISTORY The following key questions should be a part of every patient history: 1. When did the rash appear, and how quickly did it progress?  The most lethal rashes often progress rapidly. Acute urticaria with anaphylaxis  2. Did the rash change over time?  ANTRAX: PUPURA THEN ULCERATE THEN BLACK SCAR TSS. SSSS, TEN : ERYTHEMATOUS RASH THEN DESUQUMATION
3. What was the progression of the rash? Where did the rash start?  Vasculitic rashes generally spread in a peripheral-to-central pattern,  *viral rashes (e.g., varicella) start centrally and spread peripherally. 4. Is the lesion pruritic? Itching is, mediated by histamine released by mast cells.  *Diffuse pruritus without a rash can be seen in biliary cirrhosis or certain cancers, especially lymphomas. *Pruritus with a diffuse rash may be from an acute allergic reaction or , dermatitis, scabies
5. Has there been any recent travel?  *  a petechial rash in someone who has been to a wooded area may be Rocky Mountain spotted fever, * typhus if travel to the southwestern United States, and a maculopapular rash that spreads from the trunk to the extremities.
6. What medications is the patient taking? Cutaneous drug reactions occur in about 2%-3% of hospitalized patients and 1% of OPD CASES 7. What is the patient’s past medical history ? ** patients with an artificial heart valve, cardiac valvular lesions, or IV drug use may have endocarditis.  **herpes zoster associated with HIV **erythema multiforme following herpes simplex or mycoplasma infections.

STEVEN-JOHNSON SYNDROME It is characterized by a prodrome of malaise and fever, followed by the rapid onset of erythematous or purpuric macules and plaques . The skin lesions (<10%) progress to epidermal necrosis and sloughing . * Mucosal membranes are affected (ocular, oral, and genital)  .
Toxic epidermal necrolysis   involves sloughing of greater than 30 percent of the body surface area . also begins with a prodrome of fever and malaise, . temperatures are typically higher than those seen with SJS, often exceeding 39 degrees Celsius. Mucous membranes are involved in  SKIN DESUQEMQTION.

Ophthalmologic - Conjunctival lesions ,Excessive tearing sometimes occurs from obstruction of the tear punctae . Urogenital - Urethritis ,dysuria or even urinary retention . Pulmonary - dyspnea, hypoxia, bronchial hypersecretion, tracheobronchitis, pulmonary edema, bacterial pneumonitis, and bronchiolitis obliterans .
Erythema multiforme (EM) Is an acute, self-limiting, mucocutaneous reaction pattern to many viral, bacterial, protozoal and fungal infections, tumors, drugs, autoimmune states and miscellaneous conditions. The most frequent cause is HSV infection followed by mycoplasma pneumoniae. Clinical spectrum of EM ranges from mild (erythema multiforme minor) to severe form (Steven-Johnson’s syndrome-TEN complex and TEN)  Variable prodromal symptoms and a symmetrically distributed polymorphic rash classically with iris or target lesions seen on hands with a central vesicle, or erythema surrounded by a pale and then a red ring. The eruption in SJS(Severe EM) occurs preferentially periorificially or on mucocutaneous locations as painful erosions with thick adherent crusts.
Cutaneous lesions frequently begin on the extensor extremities, and may spread centripetally to other areas. Lesions are usually asymptomatic, although some patients may note pruritus or a burning sensation.  EM may also involve mucosal surfaces, presenting as painful erythematous patches, erosions, or bullae. The diagnosis of acute erythema multiforme typically is based upon the patient's history and clinical findings.  When the diagnosis is uncertain, skin biopsies are useful for establishing the diagnosis .

managment ABC ICU
**   The management of patients requires well-synchronized teamwork. **   In addition to experienced dermatologists, internists & well-trained, devoted nursing staff are needed for continuous monitoring of patients. The  pillars  in the management of such patients are  **nursing care;  **monitoring hemodynamic changes;  **fluid, electrolyte balance and nutrition;  **prevention of complication (e.g. sepsis); **prompt identification of risk factors; **& topical therapy .
Nursing care and general measures **  Patients can be managed in  burn units  or in a  specialized ward .  **   The  environmental temperature  should be maintained at 30°-32°C;alternatively, an  infrared lamp  can be used to reduce shivering & the associated energy loss. **   Use of  air-fluidized beds  & a  burn-cage  ensures patient comfort & easy handling.
Regular cleaning & removal of crusts  from the oral & nasal cavities, &  care of eyes, genitalia & perianal  region has to be ensured. *   bathing in lukewarm water (35°-38°C)  is recommended *  Introduction of an  I.V line  &  urinary catheter  or  condom drainage  are mandatory.  *  A  nasogastric tube  should be considered in the presence of severe mucosal involvement restricting oral intake or in severely ill patients.  It helps in  feeding , and assessing the  gastric emptying . *  An hourly record of the  PR, RR , BP, & urine volume & osmolality  is essential.  *  The  body temp & gastric emptying  should be recorded every 3 to 4  hours.  *  An accurate  daily intake-output chart  should be maintained.
 
Monitoring hemodynamic changes A urine output of  50-100 ml/hour  and an osmolality lower than  1020  are indicative of adequate tissue  perfusion. **  However, while assessing the adequacy of urine output in these patients,  hyperglycemia  has to be ruled out as it is commonly associated.
**  TEN   is often compared with burn injury, the fluid requirement is  2/3rd to 3/4th  of that of patients with  burns  covering the same area.
Topical management **   An oozy denuded skin should be managed conservatively.  **   In patients with TEN, the detachable epidermis is preferably left in place. **   Topical agents (0.5% silver nitrate) **  Non-physiologic lipids  (petrolatum jelly, lanolin) in vapor-permeable dressings (gauze) can be used as barrier repair agents. **  Use of  physiologic lipids  (component mixture of cholesterol, ceramide and free fatty acids in an optimized ratio of 3:1:1), accelerates the barrier repair. **  Moreover, use of these emollients prevents the skin surface from sticking to the bed or the apparel.
Other  measures **   Individual cases should be considered for  sedatives like diazepam or morphine to reduce anxiety and apprehension, and H2-blockers to prevent stress ulcers .  **  In the presence of significant  hyperglycemia, insulin  should be added as per medical advice. **  Ophthalmic care  should be provided in the form of protective ocular pads, periodic instillation of normal saline or artificial tears, and preventive measures for synechiae formation.
***  The poor prognostic factors in ASF are **older age **larger body surface area involvement **presence of severe neutropenia **early thrombocytopenia **high blood urea nitrogen level **a causative drug with long half life in drug-induced cases.
GLUCOCORTICOIDS studies result in avoiding GLUCOCORTICOIDS in children with SJS, as this therapy can cause significant side effects and the overall prognosis is good with supportive care alone.
Studies result in favor of administration of glucocorticoids to adult patients in whom SJS has been diagnosed  within 24 to 48 hours, while recognizing that the evidence of clear benefit is inadequate. We suggest administering  prednisone , 2 mg/kg daily (or an equivalent amount of  prednisolone  or  methylprednisolone ), 5-7 days .
do not  give  glucocorticoids to treat adults with TEN because of concern for increased risk of sepsis, although the evidence of harm is not conclusive.

Why a challenge rash? profound shock, renal failure,  sepsis,  adult respiratory distress syndrome. The overall mortality is 30%, and can reach 80% in the elderly.
Treatment Patients with TSS and STSS require ABCD.  Some will need vasopressors, inotropic agents,  and mechanical ventilation.  In  staph TSS, remove the source of staphylococcal colonization, such as vaginal tampons, nasal packing, or breast implants
Antibiotic therapy with anti-staphylococcal coverage is recommended.: Intravenous beta-lactamase-resistant antibiotics (oxacillin,nafcillin, cefoxitin, vancomycin, or clindamycin) should be started as soon as the diagnosis is considered.
Strep. TSS Affects mostly healthy people 20-50 yrs Affects multiple organ system with fever, hypotension, skin findings of edema, erythema or bullae. Aetiology: Invasive soft-tissue strep. Pyogenes (GAS) infection, such as cellulitis or myositis
MANAGEMENT     ABC Surgical involvement Start of antibiotics IVIG
Hemodynamic support  —  Massive amounts of intravenous fluids (10 to 20 L/day) are often necessary to maintain perfusion vasopressors (eg, dopamine and/or norepinephrine) may also be required.  Surgical therapy  —  Prompt and aggressive exploration and debridement of suspected deep-seated S. pyogenes infection is mandatory .
Antibiotic therapy Clindamycin  — Should be a first choice and should be started immediately   A retrospective review of 56 children with invasive GAS infections noted that a favorable outcome was more likely in patients who received a protein synthesis-inhibiting antibiotic (eg,  clindamycin ) compared to those who received only a cell wall-inhibiting antibiotic (eg, beta-lactams) (83 versus 14 percent with beta-lactams had a favorable outcome) .

Acute meningococcemia and meningococcal meningitis are caused by  Neisseria meningitidis ,  begin with colonization of the nasopharynx  to systemic invasion,  bacteremia,  SEPSIS and/or CNS invasion.  Untreated meningococcemia is invariably fatal.  Even with prompt treatment, the mortality rate is about 10%-20%. Common :  *  Children from 6 m to 1 yr of age  *  adult < 20 year *  Persons with complement deficiencies, protein  C&S  deficiency, or who are asplenic
The incubation period varies from 2- 10 days,  Symptoms: may begin with an upper respiratory infection. fever, chills, malaise, myalgias,headaches, nausea, and vomiting. A rash is seen in more than 70% of people with meningococcemia . Petechiae on the wrist and ankles, are the first sign of impending septicemia. The petechiae spread to the rest of the body, becoming confluent and eventually developing into purpuric
Why it is a challenge rash ? Because if untreated early and aggresively, it can lead to serious complication: Cerebral: hearing loss, local vasculitis, local cerebral infarction, subdural effusion, hydrocephalus, cerebral abscess
INVESTIGATION LP:  CSF glucose concentration below 45 mg/dL (2.5 mmol/L), a protein concentration above 500 mg/dL, and a white cell count above 1000/microL.  The polymerase chain reaction (PCR) is a sensitive and rapid tool for diagnosing meningococcal infection.  However, PCR has not replaced traditional culture methods because it cannot be used to determine antimicrobial susceptibility .
TREATMENT should be admitted to an isolation room. Supportive care involving IV fluids is crucial in the patient with overt or incipient shock., ceftriaxone (2 g q12h) is the initial antibiotic of choice to cover the most common bacterial causes of purpuric disease:  N. meningitidis, H. influenzae,  and  S. pneumoniae. OR CEFOTAXIME DO NOT DELAY TREATMENT AFTER LP IF SUSPECT
DEXAMETHASONE FOR BACTERIAL MENIGITIDIS Abstract Four hundred twenty-nine patients with bacterial meningitis were assigned on a nonselective alternating basis into one of two therapeutic regimens. Patients in Group I received dexamethasone in addition to standard antibacterial chemotherapy of ampicillin and chloramphenicol whereas those in Group II received antibacterial chemotherapy alone. Dexamethasone was given intramuscularly (8 mg to children younger than 12 years and 12 mg to adults every 12 hours for 3 days). Both treatment groups were comparable with regard to age, sex, duration of symptoms and state of consciousness at the time of hospitalization. A  significant reduction in the case fatality rate (P < 0.01)  was observed in patients with p meningitis receiving dexamethasone; only 7 of 52 patients died compared with 22 of 54 patients not receiving dexamethasone.  A reduction in the overall neurologic sequelae (hearing impairment and paresis) was observed  in patients receiving dexamethasone. This reduction was significant only in patients with meningitis; none of the 45 surviving patients receiving steroids had hearing loss whereas 4 of 32 patients not receiving dexamethasone had severe hearing loss (P < 0.05). No significant difference was observed between the two groups with regard to time for patients to become afebrile or to regain consciousness or in the mean admission and 24- to 36-hour cerebrospinal fluid leukocyte count, glucose or protein content.

Myocardial infarction in Kawasaki disease: Clinical analyses in 195 cases    .   M.D.Hirohisa Kato a ,  b ,  , M.D.Eisei Ichinose a ,  b  and M.D.Tomisaku  a ,  b a Department of Pediatrics, Division of Pediatric Cardiology, Kurume University School of Medicine, Japan   We analyzed clinical data from 195 patients (141 boys) with myocardial infarction complicating Kawasaki disease, collected from 74 major hospitals in Japan. The myocardial infarction usually occurred within the first year of illness, but 27.2% of the patients had myocardial infarction more than 1 year later.  The main symptoms of acute myocardial infarction were shock, unrest, vomiting, abdominal pain, and chest pain; chest pain was much more frequently recognized in the survivors and in older patients. The myocardial infarctions were asymptomatic in 37% of the patients. Twenty-two percent of the patients died during the first attack. Sixteen percent of the survivors of a first attack had a second attack. Forty-three percent of all survivors of the first or subsequent attack are doing well; however, others have some type of cardiac dysfunction, such as mitral regurgitation, decreased ejection fraction of the left ventricle, or left ventricular aneurysm. Coronary angiographic studies indicate that in most of the fatal cases there was obstruction either in the main left coronary artery or in both the main right coronary artery and the anterior descending artery. In survivors, one-vessel obstruction was frequently recognized, particularly in the right coronary artery.
Adult coronary artery disease probably due to childhood Kawasaki disease  H. Kato MD, Prof a ,  , O. Inoue MD a , H. Toshima MD b , T. Kawasaki MD c , H. Fujiwara MD d  an .  Abstract We have surveyed adult survivors of childhood Kawasaki disease (KD) who had coronary artery disease that could be ascribed to KD. In response to questionnaires sent to cardiologists throughout Japan, 21 patients (17 men, 4 women, aged 20-63 years) with coronary lesions and a definite (2) or suspected (19) history of KD were reported. 5 patients had presented with acute myocardial infarction, 6 previous myocardial infarction, 9 angina pectoris, and 1 dilated cardiomyopathy. 16 patients had obstructions in two or more coronary arteries. 3 had died and 18 were alive with serious sequelae (mitral regurgitation, arrhythmias, congestive heart failure). Childhood KD should be included in the differential diagnosis of coronary artery disease in young adults

    Erythema multiforme (EM)Is an acute, self-limiting, mucocutaneous reaction pattern to many viral, bacterial, protozoal and fungal infections, tumors, drugs, autoimmune states and miscellaneous conditions. The most frequent cause is HSV infection followed by mycoplasma pneumoniae. Clinical spectrum of EM ranges from mild (erythema multiforme minor) to severe form (Steven-Johnson’s syndrome-TEN complex and TEN) Variable prodromal symptoms and a symmetrically distributed polymorphic rash classically with iris or target lesions seen on hands with a central vesicle, or erythema surrounded by a pale and then a red ring. The eruption in SJS(Severe EM) occurs preferentially periorificially or on mucocutaneous locations as painful erosions with thick adherent crusts.
  • 26.
    Cutaneous lesions frequentlybegin on the extensor extremities, and may spread centripetally to other areas. Lesions are usually asymptomatic, although some patients may note pruritus or a burning sensation. EM may also involve mucosal surfaces, presenting as painful erythematous patches, erosions, or bullae. The diagnosis of acute erythema multiforme typically is based upon the patient's history and clinical findings. When the diagnosis is uncertain, skin biopsies are useful for establishing the diagnosis .

    ** The management of patients requires well-synchronized teamwork. ** In addition to experienced dermatologists, internists & well-trained, devoted nursing staff are needed for continuous monitoring of patients. The pillars in the management of such patients are **nursing care; **monitoring hemodynamic changes; **fluid, electrolyte balance and nutrition; **prevention of complication (e.g. sepsis); **prompt identification of risk factors; **& topical therapy .
  • 32.
    Nursing care andgeneral measures ** Patients can be managed in burn units or in a specialized ward . ** The environmental temperature should be maintained at 30°-32°C;alternatively, an infrared lamp can be used to reduce shivering & the associated energy loss. ** Use of air-fluidized beds & a burn-cage ensures patient comfort & easy handling.
  • 33.
    Regular cleaning &removal of crusts from the oral & nasal cavities, & care of eyes, genitalia & perianal region has to be ensured. * bathing in lukewarm water (35°-38°C) is recommended * Introduction of an I.V line & urinary catheter or condom drainage are mandatory. * A nasogastric tube should be considered in the presence of severe mucosal involvement restricting oral intake or in severely ill patients. It helps in feeding , and assessing the gastric emptying . * An hourly record of the PR, RR , BP, & urine volume & osmolality is essential. * The body temp & gastric emptying should be recorded every 3 to 4 hours. * An accurate daily intake-output chart should be maintained.
  • 34.
  • 35.
    Monitoring hemodynamic changesA urine output of 50-100 ml/hour and an osmolality lower than 1020 are indicative of adequate tissue perfusion. ** However, while assessing the adequacy of urine output in these patients, hyperglycemia has to be ruled out as it is commonly associated.
  • 36.
    ** TEN is often compared with burn injury, the fluid requirement is 2/3rd to 3/4th of that of patients with burns covering the same area.
  • 37.
    Topical management ** An oozy denuded skin should be managed conservatively. ** In patients with TEN, the detachable epidermis is preferably left in place. ** Topical agents (0.5% silver nitrate) ** Non-physiologic lipids (petrolatum jelly, lanolin) in vapor-permeable dressings (gauze) can be used as barrier repair agents. ** Use of physiologic lipids (component mixture of cholesterol, ceramide and free fatty acids in an optimized ratio of 3:1:1), accelerates the barrier repair. ** Moreover, use of these emollients prevents the skin surface from sticking to the bed or the apparel.
  • 38.
    Other measures** Individual cases should be considered for sedatives like diazepam or morphine to reduce anxiety and apprehension, and H2-blockers to prevent stress ulcers . ** In the presence of significant hyperglycemia, insulin should be added as per medical advice. ** Ophthalmic care should be provided in the form of protective ocular pads, periodic instillation of normal saline or artificial tears, and preventive measures for synechiae formation.

    DEXAMETHASONE FOR BACTERIALMENIGITIDIS Abstract Four hundred twenty-nine patients with bacterial meningitis were assigned on a nonselective alternating basis into one of two therapeutic regimens. Patients in Group I received dexamethasone in addition to standard antibacterial chemotherapy of ampicillin and chloramphenicol whereas those in Group II received antibacterial chemotherapy alone. Dexamethasone was given intramuscularly (8 mg to children younger than 12 years and 12 mg to adults every 12 hours for 3 days). Both treatment groups were comparable with regard to age, sex, duration of symptoms and state of consciousness at the time of hospitalization. A significant reduction in the case fatality rate (P < 0.01) was observed in patients with p meningitis receiving dexamethasone; only 7 of 52 patients died compared with 22 of 54 patients not receiving dexamethasone. A reduction in the overall neurologic sequelae (hearing impairment and paresis) was observed in patients receiving dexamethasone. This reduction was significant only in patients with meningitis; none of the 45 surviving patients receiving steroids had hearing loss whereas 4 of 32 patients not receiving dexamethasone had severe hearing loss (P < 0.05). No significant difference was observed between the two groups with regard to time for patients to become afebrile or to regain consciousness or in the mean admission and 24- to 36-hour cerebrospinal fluid leukocyte count, glucose or protein content.

    Myocardial infarction inKawasaki disease: Clinical analyses in 195 cases   .   M.D.Hirohisa Kato a , b , , M.D.Eisei Ichinose a , b and M.D.Tomisaku a , b a Department of Pediatrics, Division of Pediatric Cardiology, Kurume University School of Medicine, Japan   We analyzed clinical data from 195 patients (141 boys) with myocardial infarction complicating Kawasaki disease, collected from 74 major hospitals in Japan. The myocardial infarction usually occurred within the first year of illness, but 27.2% of the patients had myocardial infarction more than 1 year later. The main symptoms of acute myocardial infarction were shock, unrest, vomiting, abdominal pain, and chest pain; chest pain was much more frequently recognized in the survivors and in older patients. The myocardial infarctions were asymptomatic in 37% of the patients. Twenty-two percent of the patients died during the first attack. Sixteen percent of the survivors of a first attack had a second attack. Forty-three percent of all survivors of the first or subsequent attack are doing well; however, others have some type of cardiac dysfunction, such as mitral regurgitation, decreased ejection fraction of the left ventricle, or left ventricular aneurysm. Coronary angiographic studies indicate that in most of the fatal cases there was obstruction either in the main left coronary artery or in both the main right coronary artery and the anterior descending artery. In survivors, one-vessel obstruction was frequently recognized, particularly in the right coronary artery.

Abstract We have surveyed adult survivors of childhood Kawasaki disease (KD) who had coronary artery disease that could be ascribed to KD. In response to questionnaires sent to cardiologists throughout Japan, 21 patients (17 men, 4 women, aged 20-63 years) with coronary lesions and a definite (2) or suspected (19) history of KD were reported. 5 patients had presented with acute myocardial infarction, 6 previous myocardial infarction, 9 angina pectoris, and 1 dilated cardiomyopathy. 16 patients had obstructions in two or more coronary arteries. 3 had died and 18 were alive with serious sequelae (mitral regurgitation, arrhythmias, congestive heart failure). Childhood KD should be included in the differential diagnosis of coronary artery disease in young adults
