Other uncommon complications include erythema nodosum, con vulsions, reactive arthritis, bacteremia, urinary tract infec General Considerations tion, and cholecystitis. Occasionally infection is acquired from infected domestic dogs or cats; by contamination of the skin or No vaccine is available. Hand washing and adherence to mucous membranes with infected blood or tissues; by basic food sanitation practices help prevent disease. Hand inhalation of infected material; by bites of fleas or deer flies washing and cleaning of kitchen utensils after contact with that have been in contact with infected animals; or by raw poultry are important.

Gentamicin percent of infections are of the ulceroglandular form and and amikacin also are efficacious, more available, and familiar start as a reddened papule that may be pruritic, quickly to clinicians. A 10-day course is usually sufficient; although ulcerates, and is not very painful. Doxycycline is not usually There may be marked systemic symptoms, including high recommended for children younger than 8 years of age unless fever, chills, weakness, and vomiting. Ciprofloxa ally accompanies the ulceroglandular form or may be seen as cin also can be used in patients with less severe disease. A floxacin is not approved for children younger than 18 years, and detectable skin lesion may be absent, and localized lymphoid is not usually recommended in children unless benefits out enlargement may exist alone (glandular form). Skin primary ulcer or localized lymphadenitis, a prolonged febrile lesions are best left open. Glandular lesions occasionally disease reminiscent of typhoid fever can occur (typhoidal require incision and drainage. Laboratory Findings the prognosis is excellent in cases of tularemia that are F tularensis can be recovered from ulcers, regional lymph recognized early and treated appropriately. The ulceroglandular type of tularemia resembles pyoderma caused by staphylococci or Sudden onset of fever, chills, and prostration. The Regional lymphadenitis with suppuration of nodes oropharyngeal type must be distinguished from streptococ (bubonic form). Children should be protected from insect bites, especially those of ticks, fleas, and deer flies, by the use of proper clothing and repellents. Because rabbits are the source of most human infections, the dressing and handling of such General Considerations game should be performed with great care.

Most cases occur from June through Septem Paired acute and convalescent sera may be tested for an ber. Human plague in the United States appears to occur in antibody rise in those cases with negative cultures. Differential Diagnosis Clinical Findings the septic phase of the disease may be confused with illnesses A. Symptoms and Signs such as meningococcemia, sepsis caused by other bacteria, and Plague assumes several clinical forms; the two most common rickettsioses. Pneumonic plague, the form cat-scratch fever, streptococcal adenitis, and cellulitis. Primary that occurs when organisms enter the body through the gastroenteritis and appendicitis may have to be distinguished. Flea control is instituted and maintained with liberal use onset, but with progression over several days to severe symp of insecticides. Although the flea bite is rarely seen, the regional lymph should be warned not to handle dead or dying animals. The node usually suppurates and drains spon infected wild animals and acquire infected fleas. Bacilli may overwhelm regional lymph nodes and enter the circulation to produce septicemia. Treatment Severe vascular necrosis results in widely disseminated hemor rhage in skin, mucous membranes, liver, and spleen. Specific Measures this and circulatory collapse may result from damage by the Streptomycin (30 mg/kg/d intramuscularly in two to three endotoxin. Doxycycline is not usually recommended for children cemia without evidence of lymphadenopathy. In some series, younger than 8 years of age unless benefits of use outweigh the 25% of cases are initially septicemic. Plague bacilli that are multiply resistant to worse prognosis than bubonic plague, largely because it is not antimicrobials are uncommon but of serious concern. Patients may present initially with Mortality is extremely high in septicemic and pneumonic a nonspecific febrile illness characterized by fever, myalgia, plague if specific antibiotic treatment is not started in the first chills, and anorexia. All contacts should receive prophylaxis Because the initial focus of infection is the lung, buboes are with oral doxycycline 2. State health officials should be notified immediately about suspected cases of plague. Unencapsulated, nontypeable H influenzae frequently the mortality rate in untreated bubonic plague is about colonize the mucous membranes and cause otitis media, 50%.

The following situations require meningoencephalitis, including mycobacterial, viral, fungal, rifampin chemoprophylaxis of all household contacts to and bacterial agents. Acute Epiglottitis one household contact is younger than age 4 years and either In croup caused by viral agents (parainfluenza 1, 2, and 3, unimmunized or incompletely immunized against Hib; respiratory syncytial virus, influenza A, adenovirus), the (2) an immunocompromised child (of any age or immuni child has more definite upper respiratory symptoms, cough, zation status) resides in the household; or (3) a child younger hoarseness, slower progression of obstructive signs, and than age 12 months resides in the home and has not received lower fever. Sudden onset of contacts may need prophylaxis if more than one case has choking and paroxysmal coughing suggests foreign body occurred in the center in the previous 60 days (discuss with aspiration. Septic Arthritis Household contacts and index cases younger than 1 month of age who need chemoprophylaxis should be given rifampin, Differential diagnosis includes acute osteomyelitis, prepatel 20 mg/kg per dose (maximum adult dose, 600 mg) orally, lar bursitis, cellulitis, rheumatic fever, and fractures and once daily for 4 successive days. Erysipelas, streptococcal cellulitis, insect bites, and trauma (including popsicle panniculitis or other types of freezing Treatment injury) may mimic Hib cellulitis.

Disease is due to several bacterial toxins, the most mal coughing with an associated elevation of lymphocytes in potent of which is pertussis toxin, which is responsible for the peripheral blood, mimicking pertussis. Complications Clinical Findings Bronchopneumonia due to superinfection is the most com A. It is characterized by abrupt clinical deterioration during the paroxysmal stage, accompa the onset of pertussis is insidious, with catarrhal upper respira nied by high fever and sometimes a striking leukemoid tory tract symptoms (rhinitis, sneezing, and an irritating reaction with a shift to predominantly polymorphonuclear cough). After about 2 weeks, cough becomes may shift rapidly to involve different areas of lung. Infants and adults with tion and may provoke worsening or recurrence of paroxys otherwise typical severe pertussis often lack characteristic mal coughing. Anoxic brain damage, cerebral hemorrhage, and may worsen with intercurrent viral respiratory infection. In or pertussis neurotoxins are hypothesized, but anoxia is adults, older children, and partially immunized individuals, most likely the cause. Severe incidence of pertussis is primarily due to increased recognition pulmonary hypertension and hyperleukocytosis are associated of disease in adolescents and adults. A booster dose of vaccine with severe disease and death in young children with pertussis. The organism may particularly those younger than age 2 years, although data to be found in the respiratory tract in diminishing numbers begin support the efficacy of such preventive therapy are not ning in the catarrhal stage and ending about 2 weeks after the strong. Hospitalized children with pertussis should be iso beginning of the paroxysmal stage. Erythromycin interpretation of antibody titers may be difficult in previously is the drug of choice because it promptly terminates respira immunized patients. Differential Diagnosis A recent study suggests that 7 days and 14 days of treatment the differential diagnosis of pertussis includes bacterial, are equally effective. Treatment with clarithromycin for 7 days tuberculous, chlamydial, and viral pneumonia. Ampicillin (100 mg/kg/d in four divided doses) may also Late-onset neonatal disease: be used for erythromycin-intolerant patients. Corticosteroids reduce the severity of disease but may mask signs of bacterial superinfection.

Boys attain greater strength and mass, female genital tract and breast development. Levels of testosterone ages 111/2 and 12 years, and boys, between ages 131/2 and 14 correlate with the physical stages of puberty and the degree years. Girls who mature early will reach peak height velocity In boys, the quantity of body fat increases before onset of sooner and attain their final height earlier. Girls who mature the height spurt, continues until the growth spurt has finished, late will attain a greater final height because of the longer and then gradually increases. Girls, by contrast, store fat gradually from about related to skeletal age at onset of puberty as well as genetic 6 years of age and do not decrease the quantity of fat, although factors. There is an increase in subcutaneous fat developmental stages than with pubic hair stages. The first sign of puberty in the male, usually between ages 10 and 12 years, is scrotal and testicular growth. The appearance of pubic years but increases rapidly between ages 12 and 13, with the peak height velocity reached at age 131/2 years.

Meticulous histon is important as underdiagnosis is common and many patients suffering from depression, receive inadequate treatment. If medications are effective, continue for 3 months and then withdraw at 25 mg/week. Clinical Features Hyperactivity usually goal oriented, over generosity, extravagance, disinhibition (promiscuity, drug abuse), irritability, accelerated speech, infectious elated congruent mood, grandiose delusions enhanced self esteem, insomnia, weight loss (no time for food). In severe forms patient appears disorganised, may be violent and has legal involvement. Use psychiatric community nurses and social workers in involving family to understand the illness and helping the family in rehabilitation of the patient into community activities. Caution: Aim to use lowest dose that is therapeutic in cases of long term use to minimize risk of side effects. Insomnia can be a symptom of most other psychiatric and physical disorders which should be excluded. May occur in the following conditions: Depression, schizophrenia, under influence of alcohol/drugs, under severe social problems or stress, personality disorder. Clinical Features General malaise, joint pains, joint mobility not affected, joint not red, not warm, not tender or only slightly tender. Pain becomes more severe as attack progresses, but subsides spontaneously in 4 days. Initially intercritical periods are long but later acute attacks occur more frequently. If arthritic attacks frequent, renal damage present or serum uric acid significantly elevated, serum uric acid should be lowered. Joints commonly involved are cervical and lumbar spines, the knees and hip as well as the hands and feet. Clinical Features Symmetrical peripheral polyarthritis mostly of small joints (warm, painful, stiff, swollen). ExtraArticular: fever, weight loss, lassitude, anaemia, subcutaneous nodules, splenomegaly, lyinphadenopathy, keratoconjuctivitis, pericarditis, pleuritis. Drug treatment is similar to that in adult type except that aspirin is used with caution because of concerns of Reyes syndrome. Clinical Features score 0 1 2 Heart rate (per minute) Absent Less than 100 Over 100 Respiration effort Absent Irregular, slow Regular Muscle tone Limp(floppy) Some flexion of arms, legs Well flexed, active motion Reflex irritability (nasal catheter) No response Some motion, grimace Cries Colour Blue, pale Pink body, blue extremities Completely pink Causes of neonatal asphyxia and anoxia include placental accident (abruptio placentae), cord prolapse and cord compression, maternal administration of drugs which depress respiration. Clinical Features Irregular foetal heart: Foetal bradycardia or tachycardia (normal foetal heart; 120140/min). The lungs may be ruptured during resuscitation causing pneumothorax and surgical emphysema. Liver, spleen and adrenal damage may cause severe bleeding and associated hypovolaemic shock. K haemorrhage 4050% of babies below distress, Convulsions, Fever Conservative 1500 gms. Does not slowly subside but skull bones due to trauma cross midline Bilateral or may become during delivery unilateral infected calcified or lead to jaundice or anaemia. Sternomastoid tumour Tear of sternomastoid Lump on the side of neck Gentle passive muscle during delivery appearing within first two physiotherapy to (especially breech). Long bones Healing takes place so readily that only minimal splinting is necessary, even where there is misalignment. Clinical Features Uniform enlargement of the head before birth causing obstructed labour or developing insidiously after birth. Cleft lip results from abnormal development of the medial nasal and maxillary processes during their development. Timing Operations may be done soon after birth: gives best aesthetic results between 612 weeks. This is the optimum timing as other congenital abnormalities have been excluded, baby is showing steady weight and is safe for anaesthesia. The baby should be transported under the above circumstances to a specialist centre equipped for this type of operation. In some other cases gastrotomy is necessary to allow time for correction on intercurrent conditions. Congenital abnormalities are frequently multiple: a careful general examination of the baby is an important prerequisite. Do an Xray (Invertogram) 6 hours after birth (air has collected in the large intestine). Low abnormalities these are easy to diagnose, simple to treat and the out look is good. Phototherapy is not an alternative to blood exchange transfusion where it is indicated. In their presence exchange transfusion will be required to be done at a lower level: sepsis, prematurity, acidaemia, hypothermia, administration of sulphonamide, hypoglycaemia. Exchange transfusion the exchange transfusion should be carried out over 45 60 minutes period alternating aspiration of 20 ml of infant blood and infusion of 20 ml of donor blood. The goal should be an exchange of approximately 2 blood volumes of infant (2x85 ml/Kg). Complication Kemicterus: Brain damage due to deposition of bilirubin in the basal ganglia and brain stem nuclei. Risk of kemictenis is increased in preterm infants with high bilirubin concentrations, low serum albumin concentrations or those on certain drugs such as ceftriaxone and aspirin. Diagnosis Symptoms include lethargy, poor feeding and vomiting, opisthotonos, oculogyric crisis seizures and death may follow. Maternal: Acute febrile illness, malaria, pneumonia, chronic diseases and uterine abnormality. It is characterized by: Tachypnoea, respiration rate more than 60 per minute, expiratory grunt and cyanosis, intercostal, subcostal and sternal recession, flaring of alae nasi.

Deaths Immunosuppressive Potential occurred between 16 h and day 1 except for 1 on day 6. A lethal dosage for dogs was for 14 days, after which they were killed and necropsied. Diarrhea and emaciation in 2 rabbits and erythema were the only physical observations. The animals were observed for 14 days, after which they were Two mg/kg of 5%, 10%, and 25% w/v aqueous Linear killed and necropsied. Diarrhea was the Alkylbenzene Sulfonate solution was applied to the skin (site only clinical sign. No significant observations were made at unspecified) of rabbits (number, species, and sex unspecified) necropsy. Linear Alkylbenzene Sulfonate had a nominal chain length of 12 carbon atoms (range, C9-C12), Acute Intravenous Toxicity an average molecular weight of 346, and was 39. Short-term Oral Toxicity Alkyl Aryl Sulfonate Sodium Dodecylbenzenesulfonate Hine et al. No controls were exhibited gelatinous diarrhea containing traces of blood in 90% used. Necropsy revealed bloody feces, and slight There were no deaths during the treatment period. Mortality was 0, 2, 6, 8, and incidences of wheezing, nasal discharge, rough fur, a blood-like 12 discharge around the eyes or nose, excitability, and unthriftiness. The authors these observations were greater in the 10, 000 and 20, 000 ppm concluded that Alkylbenzensulfonate was not classified as a toxic groups. The authors applied the product (5% aqueous) to the backs of rats granular livers or kidneys. There were no clinical 1 rat was slightly distended with urine and another rat had marked signs. One rabbit showed a +1 erythema at day 11 which was reduction in body fat stores (Hazleton Laboratories 1956). One dog in the low supplemented diet at 100 ppm and water containing 1000 ppm dose group developed anorexia that worsened over time. Necropsy provided ad libitum; consumption of both was measured every 2 revealed an excess of mucous and bile in the small intestine and days. There was some accentuation of the lobular markings of the liver in the dogs that No significant differences in feed or water consumption were died at 3 weeks. Histological examination revealed only a few observed between treated and control groups. In group 5, discrete foci of leucocyte infiltration in the cortex of the kidneys Sodium Dodecylbenzenesulfonate only, the relative liver weight of 1 mid-dose dog. Iron concentrations increased Short-term Oral and Subcutaneous Toxicity in groups 7 and 8; which the authors suggested was probably due Linear Alkylbenzenesulfonate to the hemolytic action of Sodium Dodecylbenzene-sulfonate. There was an increase in the occurrence of and liver triglyceride and nonesterified fatty acid concentrations chronic inflammatory cell infiltration (mainly fibroblasts) at the were observed in any group (Itokawa et al 1975). There were Alkylbenzenesulfonate injection-associated pseudocysts, hemorrhage, and necrosis. Rabbits (number, gender, and strain unspecified) were dosed with 13 #30% Linear Alkylbenzenesulfonate for several weeks (Sadai and unremarkable (Industrial Bio-Test Laboratories, Inc. The control group was fed the basal diet incorporated with Sodium Dodecylbenzenesulfonate sodium sulfate (0. All dogs in the test groups consumed less into the feed of weanling Sprague-Dawley rats (n = 20; 10 males, feed the first week of the test period, then increased consumption 10 females) for 90 days. There was no evidence of kidney or liver females) were fed either the basal diet or the basal diet dysfunction. Body weights and weight gains were similar between into the feed of weanling Sprague-Dawley rats (n = 20; 10 males, groups; the high-dose male group had decreased growth but did 10 females) for 90 days. There were no differences females) were fed either the basal diet or the basal diet in the hematological studies and urinalysis among groups. All rats were fed ad were no gross pathological findings attributable to Sodium libitum. Gross and microscopic histopathological studies were unremarkable (Industrial Bio-Test There were no mortalities or clinical signs observed during the Laboratories, Inc. Body weights and weight gains were similar between the controls and all treatment groups. Feed consumption of the treatment groups was into the feed of Beagle dogs (n = 6; 3 males, 3 females) for 90 below that of the control group for the first few weeks of the days. Body weights and weight gains were similar among into the feed of weanling Sprague-Dawley rats (n = 20; 10 males, the controls and the low and mid-dose groups. After the test period, the rats were killed group had decreased body weights and weight gains, especially and necropsied. The dogs in the high-dose group had decreased feed females) were fed either the basal diet or the basal diet consumption; the males in the mid-dose group has a slightly incorporated with sodium sulfate (0. There was microscopic evidence of hepatotoxic effects in There were no mortalities or clinical signs observed during the the high-dose group; the livers of 4 dogs had mild degenerative test period. Body weights and weight gains were similar between changes in the form of slight hepatocellular edema without the controls and the low and mid-dose groups; the high-dose evidence of hepatic cell loss. A fifth dog, that was killed early males and female group had decreased growth rates that only due to poor condition, had extensive hepatocellular degeneration reached significance in the females. Absolute organ weights the depressed weight was likely due to palatability issues. Organ/body ratios were increased were no differences in the hematological studies and urinalysis among dogs in the high-dose group. There were no gross pathological findings this was due to weight loss of this group (Industrial Bio-Test attributable to Sodium Dodecylbenzenesulfonate ingestion. Minor histologic changes were observed alcohol polyglycolether sulfate in drinking water (Arthur D. A slight decrease in growth rate was observed for male Alkylbenzene Sulfonates; the severity of the lesions increased at rats given 2. The animals a decrease in body weight gain, tissue damage in the cecum and were given untreated water after 22 weeks; an increase in body liver, and increased severity of renal lesions, specifically weight gain was observed and control values were attained by glomerular atrophy and necrosis of renal tubules, were observed. Mild necrosis of intestinal mucosa with hemosiderosis Rats (number, gender, and strain unspecified) were fed ~5000 of the spleen, liver, and kidneys were observed at microscopic ppm (0. Linear observation was a slight decrease in body weight gain for females Alkylbenzene Sulfonates had a nominal chain length of 12 carbon of the 1, 000 mg/kg/d group compared to controls. There was no atoms (range C to C), an average molecular weight of 346, and 9 12 difference between treated and control groups in hematologic or was 39. Body weights and hemorrhagic necrosis of the intestine and infiltration of chronic feed consumption of approximately 50% of the rats (males and inflammatory cells were observed in dogs given 10 mg/kg and females) were measured weekly. Hematology tests and urinalysis hemosiderosis of the liver and spleen was observed in dogs were performed on samples obtained from the remaining rats administered 100 and 1, 000 mg/kg (Arthur D. At study termination, all animals were Sodium Alkylbenzenesulfonate killed for necropsy. Rats (number, gender, and strain unspecified) were dosed orally Rats fed 4% Sodium Alkylbenzenesulfonate grew very little and with #0. Linear Alkylbenzene Sulfonates Alkylbenzenesulfonate Three groups of Sprague-Dawley rats (10 males, 10 females per Hine et al. A control ~2%, unsulfonated oil ~1%; 1, 10, or 2 ppm) into the feed of group of 20 rats was fed untreated diet for the same time period. At the end of the treatment period, Body weights and feed consumption were measured weekly. There were no clinical signs Hematologic studies and urinalysis were performed on samples during the treatment period. One rat in the low-dose group died taken from 5 males and 5 females from each group prior to dose in week 3 due to non-treatment causes. No differences group had increased kidney weights compared to controls; there were observed in body weight, feed consumption, survival, was no evidence of kidney damage. There were no morphologic hematologic values, urinalysis, organ weights, or organ-to-body lesions caused by Alkylbenzenesulfonate. Four of the Alkylbenzene Sulfonates in the diet (~40 mg/kg/d) did not dogs gained weight (2. The authors There were no behavioral or clinical signs in any of the treatment concluded that the kidney abnormalities were not related to groups. Mortality was higher in the applied to shaved areas on the dorsolateral aspects of the 200 ppm group; this was probably not related to treatment. Gross necropsy results were Test sites of 3 males and 3 females were abraded on the first comparable between controls and treatment groups. The test sites were rinsed 1 h after no characteristic findings through histopathology. Three negative control groups of 12 rabbits per group weight ratios were comparable between controls and treatment were treated in the same manner as the test group, but no dye was groups (Hazleton Laboratories 1956). Due to poor palatability, the high dose was adjusted to 13 weeks, all animals were killed and necropsied. At the end of the test period, the dogs No clinical signs of toxicity due to test substance administration were killed and necropsied. Body weight gains of the test animals were at the high-dose group was observed to have comparative weakness least equal to those of the controls. There were no differences in body weights weights may have been statistically different than the combined in the low and mid-dose groups; there was reduced weight gain value of the three control groups, but no difference was observed in the high-dose group. Feed consumption was decreased in the when test group weights were compared with values from high-dose group throughout the test period. The male dogs in the individual control groups; the differences were not accompanied mid-dose group also had decreased feed consumption, but to a by histologic evidence of toxicity. Hematologic studies revealed lower values for the blood urea nitrogen values for all test rabbits and the hemoglobin, hematocrit, and erythrocyte counts in the high-dose leukocyte count for male rabbits were increased and the group. The urinalysis revealed methemoglobin value for female rabbits was decreased compared no differences among groups. Neither gross nor microscopic lesions Microscopic examination revealed that the livers of 4 of the dogs due to test substance administration were observed. A in the high-dose group had mild degenerative changes in the form semipermanent hair dye formulation containing 0. A fifth dog had extensive hepatocellular degeneration Linear Alkylbenzenesulfonate associated with a mononuclear infiltrate (this dog was killed Rabbits (number, gender, and strain unspecified) were given 2 ml shortly before the conclusion of the test period due to poor applications of #10% Linear Alkylbenzenesulfonate (2 mg/kg) to condition). Some organ/body ratios were increased in the high abraded skin daily for 28 days and to intact skin for 91 days. The authors suggested that this was due to decreased systemic toxicity was observed (Arthur D. Feed and water the end of the treatment period the remaining rats were killed and consumption were measured every 2 days. The authors conducted a parallel study to compare consumption There were no differences in feed or water consumption between from drinking water. The rats (n = 40, 20 females, 20 males) any of the treated groups and the control group. Dodecylbenzenesulfonate, body weights were significantly In the feed study, there were no differences between control and decreased and liver weights significantly increased when treatment groups with regard to mortality, body weights, feed compared to the controls. Swelling of individual hepatic cells, consumption, hematological tests, or biochemical tests. There pyknotic nuclei, cytoplasmic vacuolation, and other degenerative were no lesions observed in the test groups. There was an increase in consumption in the test groups After 7 months, the testicular weights had decreased in male rats with no other signs of stress. The authors concluded microscopic examination, degeneration was considerable in the that there was no evidence of toxicity by Sodium testes of these rats. Necrosis of the seminiferous tubules, lost of Alkylbenzenesulfonate at these levels (Tusing et al. Total hepatic cholesterol concentrations increased with test article During months 4, 11, 15, and 21, blood was obtained from the administration. Organ to body weight observed in either serum alkaline phosphatase or choline esterase ratios for rats of the high-dosage group were not different at these activities. At study termination, no differences activity decreased; this decrease was greater in rats that received in body weights or organ-to-body weight ratios were observed for both substances. No significant difference in Mg-dependent any of the test groups compared to the controls. Inflammation, Ocular Irritation principally neutrophilic associated with substantia propria, was noted at 3 h and no longer evident on day 14. No evident on days 4 or 7; inflammation was no longer evident on irritation was observed. Neovascularization associated with the anterior stroma was observed beginning on day 2. Inflammation associated with Sodium Decylbenzenesulfonate the iris/ciliary body occurred in one rat at day 1. At day 35, 2 rats Three drops of a 1% Sodium Decylbenzenesulfonate solution still had not fully recovered (Maurer et al. On day 2, the rabbit was Concentrations of $1% Linear Alkylbenzenesulfonate produced dosed twice; the second dose was administered 3 h after the first. The eyes were observed after Alkylbenzenesulfonate (alkyl aryl sulfonate $40%, moisture 3 h. Half of each group was then killed and the eyes and eyelids ~2%, unsulfonated oil ~1%; 0. There was a moderate on days 1, 2, 3, 4, 7, 14, 21, 28, and 35 then killed and the eyes response that disappeared by the final reading. Three rats treated in the same manner, denudation of the epithelium and neutrophils in the substantia with the exception that olive oil or water only was applied, served propria. On day 5, the rats were killed and denudation of the epithelium as well as edema and neutrophils in skin samples from the application site were prepared by two the substantia propria. At 35 days, microscopic examination of methods to determine proline hydroxylase activity. Erythema the rabbit conjunctiva showed a decreased prominence of goblet was visible on day 3; on day 5 erythema was evident on 3 rats. Proline Alkylbenzenesulfonate was a mild irritant (Maurer and Parker hydroxylase activity was increased three-fold for both methods of 1996). Regeneration was observed beginning on day 1 and no longer In a study by Naruse et al. The mice were killed 3 h after dosing and dermal irritant in rabbits; a 1% solution did not produce any the s. The dermal irritation of of 1 corresponded to a weak reaction, 2 to an intermediate a 2 g/100 ml aqueous solution of C12 Linear Alkylbenzene reaction, and 3 to a strong reaction. After patch removal, any residual test material was In a cumulative open patch test, a 2. After 24 and 72 h, the primary irritation values were of C12 Linear Alkylbenzenesulfonate (97. Readings were not taken on 2 intact and 2 diameter tubes was applied to the same site on the shaved backs abraded sites. The dermal irritation score for In the short-term dermal toxicity study reported by Arthur D. A product containing described earlier, in which rabbits (number, sex, and strain Alkylbenzenesulfonate (alkyl aryl sulfonate $40%, moisture unspecified) were administered 2 ml applications of #10% Linear ~2%, unsulfonated oil ~1%; 1, 10, or 20 ppm) was applied to Alkylbenzenesulfonate (2 mg/kg) on abraded skin daily for 28 occluded skin for 24 h. The skin was washed and evaluated days and on intact skin for 91 days, severe dermal irritation was immediately and at 48 and 96 h. There was moderate rabbits were either treated for 28 days using an abraded test site edema, erythema, and scabbing of the abraded skin that returned or for 91 days using an intact test site with a 10% solution of a to normal. Moderate dermal irritation and abraded) on the backs of albino rabbits and the areas were was observed. The covering was removed and the areas read Three 6-h applications of a 1% (w/v) aqueous solution of Linear immediately and at 72 h. There were no readings taken for the Alkylbenzenesulfonate produced primary skin irritation using intact skin (no explanation given). Dermal Sensitization Moderate to severe erythema and moderate edema, which were Linear Alkylbenzenesulfonate still evident after 7 days, were observed by the third application. Guinea pigs (number unspecified) were injected intradermally Upon microscopic examination after 7 days, a moderate degree with a 1% w/v aqueous solution of Linear Alkylbenzenesulfonate of hyperkeratosis and epidermal acanthosis with crusting focally and challenged topically (Arthur D. There was a slight decrease in maternal weight gain produced only weakly positive responses. The number of Alkylbenzenesulfonate (with >90% of the alkyl chain lengths for dead pups increased in the high-dose group. There were no the mixture in the range of C10 to C14) ws tested at induction congenital malformations observed in either treatment group concentrations of 2% to 100% followed by challenge (Omori et al. Charles River rats that were being used in a chronic toxicity study Alkylbenzenesulfonate were concurrently used in a 3-generation reproductive study Hine et al. Twenty male and 20 female rats from each Alkylbenzenesulfonate (alkyl aryl sulfonate $40%, moisture group were fed a diet containing 0, 0. There were no into the backs of albino guinea pigs (n = 3) on alternate days for effects observed associated with Linear Alkylbenzenesulfonate 10 injections.
