Naumann ~7 in 1949 skin care doctors generic trecifan 20mg overnight delivery, reported cerebrospinal fluid levels of urea to be somewhat higher than normal antemortem blood levels skin care 4 less best order trecifan. Nevertheless skin care industry cheap trecifan 10mg without prescription, Naumann considered the concentration in cerebrospinal fluid more closely reflected antemortem concentrations in serum than levels obtained from the analysis of postmortem blood skin care trade shows generic 5 mg trecifan. Jenkins 39 reported in 1952, that the postmortem levels of urea in cerebrospinal fluid were the same as, or somewhat lower than, the blood levels at death. He considered that the cerebrospinal fluid level could be taken as a reliable indicator of antemortem urea retention. Fekete and KerenyF 5 in 1965, reported that concentrations of urea in cerebrospinal fluid were constant for the first 36 hours after death, irrespective of the time of collection; the upper limit of the postmortem normal was found to be 25 to 30 mg/dl. Hamilton-Paterson and Johnson 34 found that there is a progressive increase in nonprotein nitrogen with increasing time after death. This increase has been verified by SchleyerJ 5 He demonstrated there was, in general, an arithmetic increase in the concentration during the first 30 hours post mortem, following which the rate of increase slowed. Values greater than 80 m g / d l found in the cisternal cerebrospinal fluid were of no use in evaluating the postmortem interval. Bollinger and Carrodus 4 in 1938, demonstrated that concentrations of creatinine in cerebrospinal fluid reflected the blood concentrations and remained constant after death. N a u m a n n felt that mild degrees of prerenal uremia produced no significant increase in levels of creatinine. This observation has been substantiated by several workers and most extensively studied by Schourup and SchleyerJ 5 these investigators have demonstrated, in general, an arithmetic increase in values with longer intervals of time after death and considered the procedure to be of some use in estimating the postmortem interval for the first 20 hours after death. Ozsvath is quoted by Schleyer 75 as having reported that generally there is a linear increase of ammonia in cerebrospinal fluid with increasing time after death. Concentrations of less than 1 m g / d l were found immediately after death but increased to over 8 mg/~dl by 60 hours post mortem. Bollinger and Corrodus 4 demonstrated that in contrast to creatinine, creatine definitely increased in the cerebrospinal fluid following death. Naumann "~7 found that concentrations increased progressively with increasing postmortem time. Naumann ~ demonstrated that urobilinogen will diffuse from blood to cerebrospinal fluid whenever the blood level is high and the cerebrospinal fluid-blood barrier is disturbed. Naumann 53 found in a study of 43 icteric individuals that total bilirubin was demonstrable in the cerebrospinal fluid by the method of Malloy and Evelyn. Direct acting bilirubin analyses were found to be in a cerebrospinal fluid to serum ratio of 1:45. Dito 18 determined glutamic oxalacetic transaminase in cerebrospinal fluid on 73 cadavers at postmortem intervals varying from 2 to 70 hours. There was noted to be a progressive increase in enzymatic activity as the postmortem interval lengthened. However, an accurate estimate of the postmortem interval could not be made from a single determination because of the wide range of values obtained. Naumann 59 demonstrated that the concentration of many electrolytes changed significantly after death but not with a sufficiently close correlation with time to serve as a means of determining the postmortem interval. Values found for anions and cations in 131 cases where specimens were removed an average 101,4 hours after death are compared to normal antemortem values as follows: Postmortem mEq/L 127. They noted the concentration increased in proportion to the logarithm of the time interval for as long as 70 hours after death. Naumann 59 believed that the potassium increase was statistically predictable only; it could not be used for predicting time of death in an individual case. Fraschini and associates 29 also found increasing levels of potassium with increasing time after death and thought this might have forensic usefulness.

There is insufficient dermal interstitial neutrophilia to make a diagnosis of a neutrophilic dermatosis C acne pistol boots purchase trecifan 20mg mastercard. Changes of acute urticaria are seen together with subtle vessel wall damage with surrounding nuclear dust D acne surgery order trecifan australia. There are insufficient changes in the blood vessels and insufficient numbers of eosinophils to make this diagnosis E acne 6 months after accutane order generic trecifan from india. Although these changes could be seen in patients with lupus erythematosus but there are insufficient inflammatory changes at the basement membrane zone or around appendages to make this diagnosis acne pistol boots order 30 mg trecifan. Question Based on the combination of clinical information and histopathology, this patient should initially be evaluated for: A. Given the combination of clinical information and the histopathology, this is the best answer as this patient may be hypocomplementemic or may have other signs and symptoms to suggest a connective tissue disease or lupus erythematosus. The clinical description of the lesions is not typical for ordinary "hives" or urticaria and this clinical information combined with the pathology would not suggest a usual cause of urticaria in this patient. Malignancy has been reported in patients with cutaneous vasculitis but given the clinical information and the histopathology, this diagnosis would not be highly likely and would not be the focus of the initial workup for this case. The clinical description of the skin lesions combined with the histopathology do not suggest a contact sensitivity where one would expect to see spongiosis or eosinophilic spongiosis in addition to the dermal edema and mixed perivascular inflammation. While a specific food sensitivity could uncommonly create these changes, the combination of clinical information and histopathology does not suggest this more ordinary cause of urticarial tissue reaction. Microscopic features combine those of urticarial tissue reactions with those of subtle leukocytoclastic vasculitis. Dilated superficial dermal lymphatics are typical and the infiltrate is most often predominantly composed of neutrophils admixed with eosinophils. Blood vessel wall damage can be very subtle at times but most often the inflammatory cells can be seen traversing the wall of several vessels and the vessel 59 walls can be thickened or hyalinized slightly. Interstitial dermal neutrophilia can be seen and at times can be so prominent as to suggest a neutrophilic dermatosis, especially Sweet syndrome. These patients in addition to having dermal neutrophilia may also have neutrophils coalesced near the interface of the epidermis and dermis, closely mimicking an autoimmune blistering disease or bullous lupus erythematosus. Biopsy for direct immunofluorescence may show granular basement membrane zone fluorescence in addition to vascular fluorescence with several conjugates including IgM and C3. Skin lesions are urticarial-like but have some pain associated with them instead of just itch and most often persist for over 24 hours before resolving, leaving a bruised area at times. The skin lesions can be located in any area and are not necessarily photo-distributed. Patients with hypocomplementemia typically also have some degree of joint pain as well as potentially abdominal pain and chest pain. These same patients may have several criteria for lupus erythematosus but most often do not fulfill sufficient criteria for diagnosis of systemic lupus erythematosus. Those patients with normal complement should be evaluated in an identical fashion as those above but in addition depending on age, gender and other detailed clinical information may need a systemic workup to eliminate a systemic cause which can range from drug sensitivity to malignancy. The histopathologic changes may be under appreciated in terms of the degree of difficulty this disease can pose to patients and careful clinical correlation is always needed. Clinicopathologic correlation of hypocomplementemic and normocomplementemic urticarial vasculitis. A 4mm punch biopsy specimen was taken from crown of the scalp of a 45 year old AfricanAmerican woman. Prevalence increases with age as women are most commonly affected in the late second or third decade of life, and many do not seek treatment until the hair loss is extensive and/or permanent. In cicatricial alopecias, the hair follicle is destroyed and replaced by fibrous tissue. Two 4-mm punch biopsies of an active edge should be obtained to confirm diagnosis; one for horizontal and the other for vertical viewing histopathologically. In late stages, there is loss of sebaceous glands and hair follicles with prominent hyalinization or fibrosis of the dermis.

Nuclear beta-catenin expression distinguishes deep fibromatosis from other benign and malignant fibroblastic and myofibroblastic lesions acne used cash purchase 40mg trecifan with amex. Myofibroma acne practice purchase trecifan on line, along with myopericytoma and glomus tumors skin care korean products generic trecifan 20 mg amex, represent a spectrum of tumors of perivascular myoid cells acne 4 dpo order 40 mg trecifan. Myofibroma usually appears during the first two years of life and is more common in males. Common sites of involvement include distal extremities, proximal extremities and head and neck. Some areas of the tumor will appear more cellular composed of short spindle cells surrounding hemangiopericytomatous (branching) blood vessels. Cellular neurothekeoma is a confusing entity that was initially thought to be linked to dermal nerve sheath myxoma. However, due to difference in clinical presentation and immunoprofiles, current thinking is that cellular neurothekeoma is most likely of histiocytic or fibroblastic rather than nerve sheath derivation. These tumors are more frequent in young females and the most common site of involvement is the head and neck region. Histologically, cellular neurothekeomas are composed of nests of epithelioid to slightly spindled cells surrounded by collagen/fibrosis. Features such as cytologic atypia and a high mitotic rate do not seem to affect prognosis. Neurothekeoma: an analysis of 178 tumors with detailed immunohistochemical data and long-term patient follow-up information. Cellular neurothekeoma: analysis of 37 cases emphasizing atypical histologic features. Desmoplastic fibroma is a benign mesenchymal tumor that is more common in males and usually presents in the 5th to 7th decades. Histologic examination reveals a hypocellular proliferation of bland spindled to stellate shaped cells in a collagenous or myxocollagenous background. Mammary-type myofibroblastoma is a benign tumor likely linked to spindle cell lipoma and cellular angiofibroma by loss of 13q14. Mammary-type myofibroblastoma typically presents in adults but demonstrates a wide age range (35-85 years). Although classically described in the breast of male patients, this entity may be found at a variety of soft tissue sites including the inguinal/groin region, vulvovaginal area, buttock and abdominal wall. Mammary-type myofibroblastoma are generally circumscribed but may reach greater than 10 cm in size. Histologic examination reveals a proliferation of bland spindled cells admixed with thick, ropey collagen and variable amounts of mature adipose tissue. However, the tumors may also exhibit reactivity for smooth muscle actin and estrogen receptor. Cellular angiofibroma: analysis of 25 cases emphasizing its relationship to spindle cell lipoma and mammary-type myofibroblastoma. Chondroid lipoma is distinct but extremely rare lipomatous tumor composed of vacuolated cells admixed with mature fat in a myxochondroid background. While usually deep-seated (intramuscular), chondroid lipomas may also occur in the subcutis. The metastatic deposits usually present as flesh coloured nodules that are tender, may be itchy, and can ulcerate. Skin metastasis from a thyroid carcinoma is rarely a presenting feature of an underlying malignancy. The prognosis is usually dismal because it usually occurs in the context of disseminated neoplastic disease. Histologically several variants with different histological grading have been described. Basically, the lesion shows complex, branching, randomly oriented papillae with fibrovascular cores associated with follicles with frequent dense fibrosis.

Fibroblastic rheumatism has not been described in association with immunobullous disease. Fibroblastic rheumatism: a report of 4 cases with potential therapeutic implications. An unusual case of polyarthritis, skin nodules and patchy skin thickening: fibroblastic rheumatism. Fibroblastic rheumatism: fibromatosis rather than non-Langerhans cell histiocytosis. Frontal fibrosing alopecia characteristically causes a recession of the frontal and preauricular hairline. Other forms of alopecia that can occur in this distribution are traction alopecia and alopecia areata B. This typically affects the lateral eyebrows causing erythema and pitted scarring C. This can affect any part of the scalp and does not typically affect the frontal hair line E. This can affect any part of the scalp and early on resembles a follicular cyst the histologic findings in frontal fibrosing alopecia most closely resemble those of which disease: A. While both diseases are examples of lymphocytic scarring alopecia, the histologic findings of frontal fibrosing alopecia are identical to lichen planopilaris B. The histologic findings in frontal fibrosing alopecia are indistinguishable from lichen planopilaris C. Traction alopecia is typically non-inflammatory, although follicular dropout can occur D. Folliculitis decalvans is classified as a neutrophilic scarring alopecia, and causes neutrophilic folliculitis, a neutrophilic infiltrate with admixed lymphocytes and plasma cells, and interfollicular fibrosis E. Dissecting cellulitis is classified as a neutrophilic scarring alopecia, and causes a deep inflammatory infiltrate of neutrophils, lymphocytes and plasma cells, granulation tissue and formation of sinus tracts Clinical Features Frontal fibrosing alopecia is a recently described scarring alopecia that is being seen with increasing frequency, felt to be a variant of lichen plano-pilaris. It typically affects postmenopausal women, causing recession of the frontal and preauricular hairline. Loss of eyebrows occurs in over 50% of patients, and loss of body hair can occur as well. On close inspection some patients will exhibit perifollicular erythema and fine scale, especially when the disease is active, but this is not always present, especially in sites other than the scalp. Other clinical findings include individual hairs seeming to be on the forehead in front of a receded hairline ("lonely hairs"), a fine sandpaper-like rash on the temples, and glabellar red dots. Facial papules in frontal fibrosing alopecia: evidence of vellus follicle involvement. Glabellar red dots in frontal fibrosing alopecia: a further clinical sign on vellus follicle involvement.

First skin care associates 30 mg trecifan free shipping, it may represent a lack of adequate toilet-training or of adequate response to training acne 7 weeks pregnant cheap trecifan 30 mg amex, with the history being one of continuous failure ever to acquire adequate bowel control acne 6 dpo quality 10 mg trecifan. Second skin care bandung order trecifan 5mg on-line, it may reflect a psychologically determined disorder in which there is normal physiological control over defecation but, for some reason, a reluctance, resistance, or failure to conform to social norms in defecating in acceptable places. Third, it may stem from physiological retention, involving impaction of faeces, with secondary overflow and deposition of faeces in inappropriate places. Such retention may arise from parent/child battles over bowel-training, from withholding of faeces because of painful defecation. In some instances, the encopresis may be accompanied by smearing of faeces over the body or over the external environment and, less commonly, there may be anal fingering or masturbation. There is no clear-cut demarcation between encopresis with associated emotional/behavioural disturbance and some other psychiatric disorder which includes encopresis as a subsidiary symptom. The recommended guideline is to code encopresis if that is the predominant phenomenon and the other disorder if it is not (or if the frequency of the encopresis is less than once a month). Encopresis and enuresis are not infrequently associated and, when this is the case, the coding of encopresis should have precedence. Encopresis may sometimes follow an organic condition such as anal fissure or a gastrointestinal infection; the organic condition should be the sole coding if it constitutes a sufficient explanation for the faecal soiling but, if it serves as precipitant but not a sufficient cause, encopresis should be coded (in addition to the somatic condition). It is important to consider the following: (a)encopresis due to organic disease such as aganglionic megacolon (Q43. It generally involves refusal of food and extreme faddiness in the presence of an adequate food supply and a reasonably competent care-giver, and the absence of organic disease. There may or may not be associated rumination (repeated regurgitation without nausea or gastrointestinal illness). Diagnostic guidelines - 225 - Minor difficulties in eating are very common in infancy and childhood (in the form of faddiness, supposed undereating, or supposed overeating). Disorder should be diagnosed only if the difficulties are clearly beyond the normal range, if the nature of the eating problem is qualitatively abnormal in character, or if the child fails to gain weight or loses weight over a period of at least 1 month. It is important to differentiate this disorder from: (a)conditions where the child readily takes food from adults other than the usual care-giver; (b)organic disease sufficient to explain the food refusal; (c)anorexia nervosa and other eating disorders (F50. Pica may occur as one of many symptoms of a more widespread psychiatric disorder (such as autism), or as a relatively isolated psychopathological behaviour; only in the latter case should this code be used. The phenomenon is most common in mentally retarded children; if mental retardation is also present, it should be coded (F70-79). However, pica may also occur in children (usually young children) of normal intelligence. When such movements occur as symptoms of some other disorder, only the overall disorder should be coded. The movements that are noninjurious include: body-rocking, head-rocking, hair-plucking, hair-twisting, finger-flicking mannerisms, and hand-flapping. All the stereotyped movement disorders occur most frequently in association with mental retardation; when this is the case, both disorders should be coded. However, the visual disability does not constitute a sufficient explanation, and when both eye-poking and blindness (or partial blindness) occur, both should be coded: eye-poking under F98. Minor dysrhythmias of this type are quite common as a transient phase in early childhood, or as a minor but persistent speech feature in later childhood and adult life. They should be classified as a disorder only if their severity is such as markedly to disturb the fluency of speech. There may be associated movements of the face and/or other parts of the body that coincide in time with the repetitions, prolongations, or pauses in speech flow. In some cases there may be an associated developmental disorder of speech or language, in which case this should be separately coded under F80. Speech is erratic and dysrhythmic, with rapid, jerky spurts that usually involve faulty phrasing patterns. The majority of the conditions covered are given only at the three-character level, but four-character codes are given for a selection of those diagnoses that will be used most frequently.

If there are concerns about weight gain that is too slow or too rapid acne young living order trecifan online from canada, measurement of weight should be carried out more frequently acne makeup buy 20 mg trecifan free shipping. Details of suitable equipment acne lesions 10 mg trecifan otc, which may be fixed or portable acne 10 buy trecifan 30mg free shipping, are available from the Child Growth Foundation. Measurement of length using a tape measure is too inaccurate to be of use for longitudinal monitoring of growth, although an approximate length may be useful as a single measure. When the method of measurement changes there is likely to be a difference in length, and measurements should be made by both methods on one occasion when switching from supine length to standing height. Measurement of length is difficult and requires careful positioning of the infant, ensuring that the back, legs and head are straight, the heels are against the footboard, the shoulders are touching the baseboard and the crown of the head is touching the headboard. Positioning of the child is also important when measuring standing height and care should be taken to ensure that the back and legs are straight, the heels, buttocks, shoulder blades and back of head are touching the measurement board and that the child is looking straight ahead. Sick infants should be measured every month and older children whenever they attend a clinic. Healthy infants have a length measurement at birth (although this is notoriously inaccurate) and no further height checks are recommended until the pre-school check [3]. Whenever there are concerns about growth or weight gain a height measurement should be made more often, although there is little point in measuring height more frequently than every 3 months. In adults, arm span is approximately equivalent to height, but body proportions depend upon age and this measurement is not generally useful. One blade is fitted under the heel of the foot and the other onto the knee, immediately behind the patella, using the outside surface of the leg. Total leg length is rarely measured outside specialist growth clinics and is calculated as the difference between measured sitting height and standing height. A number of other measures have been used in children with cerebral palsy as a proxy for height, but numbers are too small for reference standards to be established [5]. Formulas for calculating height from proxy measurements are further discussed in Chapter 29. In children, the amount and distribution of body fat is dependent on age, and does not appear to be related to health. Proxy measurements for length/height In some cases it is difficult to obtain length or height measurements. A number of Supplementary measurements the measurement of weight and length or height forms the basis of anthropometric assessment. However, these measurements on their own do not indicate whether weight increments are due to lean and fat tissue, or whether weight gained is merely fat. This can be an unpleasant procedure for young children, who are afraid of the skinfold caliper and may not remain still for long enough for accurate measurements to be taken. The equipment and technique are identical to those used in adults and the measurement is subject to the same observer Nutritional Assessment, Dietary Requirements, Feed Supplementation 7 Table 1. Skinfold thickness is not used as a routine anthropometric measure but provides valuable data in research studies. Measurement of the waist circumference can help distinguish between a high weight for age that is caused by high body lean tissue or high body fat. The waist: hip ratio in children has not proved to be a useful predictor of obesity in pre-pubertal children [7], and reference data do not exist at present for European children. These data were based on a cohort of infants who were largely formula fed during the first 6 months of life. The growth of breast fed infants differs from that of artificially fed infants, and breast fed infants tend to be longer and leaner at age 3 months [9]. Centile charts for fully breast fed infants are available from the Child Growth Foundation, and can be used for both breast and formula fed infants; however, they are based on a very small cohort of 120 infants who had solids introduced at a mean age of 15 weeks and only 40% were still receiving breast milk at 1 year of age.

The frozen section is placed (mounted) on a slide or held by other means that allow the pathologist to view the tissue under a microscope skin care 2013 buy cheap trecifan 5mg on line. When one block is sectioned and examined skin care hospitals in bangalore purchase 10 mg trecifan amex, the service of examining that first section is reported using 88331 acne 8 yr old girl order trecifan 40 mg overnight delivery. The second and subsequent sections of the same block are included in the reporting of 88331 skin care physicians buy trecifan 5mg free shipping. If another block from another area (a second block) was sectioned, the first section would be reported using 88331, and subsequent sections from the second block using 88332. Code 88332 is marked as an add-on code (one that is used only with another code), its function is to report subsequent sections that were examined. Urinalysis, molecular pathology, and chemistry Many types of tests are located under the Urinalysis, Molecular Pathology, and Chemistry subsections (81000-84999). For example, a urinalysis using a dipstick (81000-81003) would report the presence and quantity of the following constituents: bilirubin, glucose, hemoglobin, ketones, leukocytes, nitrite, pH, protein, specific gravity, and urobilinogen. Any number of these constituents may be analyzed and reported using a code from the Urinalysis subsection (81000-81099). However, if the physician ordered an analysis of the urine specifically to determine the presence of urobilinogen (reduced bilirubin) and the exact amount of urobilinogen present (quantitative analysis), you would choose a code (84580) from the Chemistry subsection. Tier 1 codes (81161, 81200-81383) report services for molecular assays that are more commonly performed. There are many conditions in which a genetic predisposition can be predicted, such as cystic fibrosis and colon cancer. Tier 2 codes 81400-81479 involve less commonly performed analyses and are arranged by the required level of technical resources and the level of physician interpretation or other qualified health professional. Hematology and coagulation the Hematology and Coagulation subsection contains codes (8500285999) based on the various blood-drawing methods and tests. A blood count is used to measure the kind and number of cells in the blood, such as red and white blood cells. To accurately code a blood count, the method and the type of the count must be documented. There are codes within the Hematology and Coagulation subsection for blood smear and bone marrow smear interpretations (85060, 85097). When a physician procures the bone marrow by means of aspiration, the service is reported with a code from the Surgery section (38220); but that is only part of the service. The other part of the service is the pathology analysis of the aspirated specimen. As the coder in a clinic setting, you may be reporting only the surgical services or only the pathology/laboratory services or a combination of both. When reporting the surgical services, always review the pathology report as a part of the code assignment, and when reporting the pathology services, always review the operative report. There are many blood coagulation tests located in the Hematology and Coagulation subsection. Great care must be taken to ensure that the correct coagulation factor has been reported based on the information in the medical record. Coagulation factor tests analyze the level of certain proteins in the blood that enable the blood to congeal properly. Low levels of a factor may result in excessive bleeding and high levels may lead to clot formation (thrombosis). This test is often performed when a patient is on a blood thinning medication and the physician wants to determine if the factor is at the optimal level. Read the medical record and code descriptions carefully before assigning the codes. Immunology Immunology codes (86000-86804) report identification of conditions of the immune system caused by the action of antibodies. Transfusion of blood and blood components is reported with codes from a variety of locations. The blood bank would provide and report the collection, processing, and storing of the autologous blood with 86890. Culture codes for the identification of organisms as well as the identification of sensitivities of the organism to antibiotics (called culture and sensitivity) are located in this subsection.

In the gut itself tuberculosis may occur in any location from the mouth to the anus skin care 2020 purchase trecifan 10 mg otc, although lesions proximal to the terminal ileum are unusual acne breakout order trecifan once a day. The most common sites of involvement are the terminal ileum and cecum acne zapping machine generic trecifan 20 mg on-line, with other portions of the colon and the rectum involved less frequently (66) skin care 777 discount trecifan 30mg online. In the terminal ileum or cecum the most common manifestations are pain, which may be misdiagnosed as appendicitis, and intestinal obstruction. A palpable mass may be noted that, together with the appearance of the abnormality on barium enema or small bowel films, can easily be mistaken for a carcinoma. Rectal lesions usually present as anal fissures, fistulae, or perirectal abscesses. However, laparoscopy or colonoscopy with biopsy may be sufficient to obtain diagnostic material. Active pulmonary tuberculosis is uncommon in patients with tuberculous peritonitis. Because the process frequently coexists with other disorders, especially hepatic cirrhosis with ascites, the symptoms of tuberculosis may be obscured. The combination of fever and abdominal tenderness in a person with ascites should always prompt an evaluation for intraabdominal infection, and a paracentesis should be performed. However, this is often not diagnostic, and laparoscopy with biopsy is recommended if tuberculosis is suspected. The symptoms, physical findings, and laboratory abnormalities associated with tuberculous pericarditis may be the result of either the infectious process itself or the pericardial inflammation causing pain, effusion, and eventually hemodynamic effects. Symptoms of cardiopulmonary origin tend to occur later and include cough, dyspnea, orthopnea, ankle swelling, and chest pain. The chest pain may occasionally mimic angina but usually is described as being dull, aching, and often affected by position and by inspiration. Varying proportions of patients in reported series have signs of full-blown cardiac constriction when first evaluated. It is assumed that in these patients the acute phase of the process was unnoticed. In the absence of concurrent extracardiac tuberculosis, diagnosis of pericardial tuberculosis requires aspiration of pericardial fluid or, usually, pericardial biopsy. Only laboratories having a sufficient volume of work and assured competence should provide clinical mycobacteriology services. Such procedures are time-consuming and employ reagents and special techniques not used routinely in the study of bacteria in other genera. Furthermore, handling of mycobacterial specimens requires special safety precautions and With the closing of most tuberculosis sanatoria in the 1970s, treatment of patients with tuberculosis moved to general hospitals and outpatient clinics. The supporting mycobacteriology services were spread diffusely through more and more laboratories, each processing fewer and fewer specimens. Recently, managed care plans that centralize laboratory processing have increased the number of specimens that are sent to regional reference laboratories for processing, further decreasing the numbers of mycobacteriology specimens processed locally. Maintenance of laboratory proficiency requires continuing and frequent performance of the required tests. When tests are performed so infrequently that it is impractical to maintain the materials and expertise required for proficiency, a decision must be made concerning referral to another laboratory for testing. In addition, because tuberculosis can be transmitted to laboratory personnel who handle clinical specimens, adequate training in proper techniques and the availability of special containment areas are required for the safe manipulation of clinical specimens. Protection of laboratory personnel and environment can be achieved by observing standard laboratory practices and techniques, using appropriate safety equipment properly, and designing a safe laboratory layout that includes proper air handling (73, 74). The laboratory and the clinicians requesting service must be confident of the results the laboratory provides.
