Imaging Studies It was previously believed that simple dilation of existing host blood vessels accounted for the increased tumor vascularity. Simple cyst Simple cysts are characterized by: · Anechoic fluid filling the cyst cavity · Thin walls · Distal acoustic enhancement No impairment of sound transmission through the mass (in other words, no loss of signal from tissues behind the cyst) Step 2: Is there a physiologic process that can account for potentially confusing findings? Corpus Luteum - can have thickened walls, circumferential color Doppler flow, and a small central lucency containing echoes that can be confusing Two simple cysts Two simple cysts next to each other can simulate a septated single cyst Hemorrhagic cyst - Can simulate septations and mural nodules. A fine network of thin linear to curvilinear echoes, sometimes called a fishnet or reticular pattern, is strongly suggestive of a hemorrhagic cyst. If one or more B-rules apply in the absence of a M-rule, the mass is classified as benign. At a cutoff value of 65 U/ml, the sensitivity is 79% (at alow specificity of 82%). The optimal clinical value is reached at 150 U/ml (sensitivity 69%, specificity 93%). At a cutoff value of 65u/mL, the sensitivity is 79% (at a low specificity of 82%). The optimal clinical value is reached at 150 U/mL sensitivity 69%, specificity 93%). High-risk imaging was defined as any complex ovarian tumor with evidence of solid or papillary components.

Becker et al, Pharmacoepidemiology and Drug Safety 2007, Jun; 16(6): 641-561 Evidence: How Much of an Impact are Drug Drug Interactions? The precise pathogenesis of avian renal disease, however, is not nearly as well described as it is in mammals. When compared to mammalian counterparts, the avian urogenital system has many structural and functional differences, which have been described previously. By better understanding the pathophysiology of renal disease, practitioners will be able to better diagnose, clinically evaluate and treat kidney disorders in birds. Various forms of specific kidney disorders that have been reported in birds are described. Part two will focus on methods of diagnosis and management of specific avian renal diseases. Many of the diagnostics and treatments discussed are rationalized and based on avian renal anatomy, physiology and an understanding of the pathophysiology behind kidney disease, all of which are covered in the first half of the chapter. Within each division are numerous renal lobules, each containing a cortex and a cone-shaped medulla (medullary cone). Avian medullary cones have no inner and outer regions as described in most mammalian kidneys. Since birds have primarily "reptilian" type nephrons, which produce isoosmotic urine, urine concentration is limited. In-depth discussions of gross and microscopic avian kidney anatomy have been covered elsewhere as referenced, but pertinent features will be discussed here. The middle and caudal renal divisions of most passerines are fused, while the caudal renal divisions are connected across the midline in herons, puffins and penguins. Neurovascular System (Including the Renal Portal System) the vascular system surrounding avian kidneys is quite complex and is one of the main reasons that renal surgery is difficult in birds. Another unique feature of avian kidneys is the presence of an arterial and venous, or dual, afferent blood supply. The cranial renal division is supplied by the cranial renal arteries, which branch off the aorta. The glomeruli and postglomerular tubular network of the middle and caudal renal divisions are supplied by the middle and caudal renal arteries, which branch off the ischiadic or external iliac arteries. For example, venous blood from the limbs is shunted straight to the caudal vena cava when the renal portal valve, within the common iliac vein, is open. Additional shunting either to the caudal mesenteric vein (caudally) or internal vertebral sinus Chapter 16 E V A L U A T I N G A N D T R E A T I N G T H E K I D N E Y S 453 Fig 16. This hawk has a moderate amount of fat covering the middle and caudal renal divisions. By route of the afferent caudal and cranial renal portal vein branches, blood is delivered to the peritubular capillary network. Blood is ultimately drained out of the kidneys via the centrolobular to the cranial and caudal to the renal and finally common iliac veins just proximal to the renal portal valve. This may increase the effect of nephrotoxic drugs and/or enhance elimination by taking the compound directly to the kidneys. Some drugs eliminated by tubular secretion and given into the leg may enter the renal portal system and be eliminated without ever entering systemic circulation. Because some of the venous afferent blood comes from the caudal mesenteric vein (v. As 454 C l i n i c a l Av i a n M e d i c i n e - Vo l u m e I I addressed under Part 1: General Mechanisms and Consequences of Renal Injury, Gastrointestinal Complications, the effect of lower intestinal disease upon the kidneys should be considered and treatment such as antibiotics for colitis instituted. There is likely an intimate association between renal function and extrarenal NaCl excretion. The caudal portion is located above the orbit, adjacent to the frontal bone, while the rostral extent is in the lateral wall of the nasal cavity, next to the dorsal and medial turbinates. Once a bird is exposed to high salt loads, there is a rapid and profound hyperplasia and hypertrophy response that results in a greatly enhanced salt-secretory capacity within 1 to 7 days. This may imply that salt glands either are infrequently evaluated or are truly uncommonly affected by disease conditions. One study found that domestic ducks induced with plumbism had high concentrations of lead in the salt glands. Also, lead toxicity results in obvious renal impairment and possibly damages the salt glands, making it difficult for wild waterfowl to adapt to different saline environments. Chickens seem to be able to "autoregulate" (keep constant) glomerular filtration rate when the arterial blood pressure range is within 60 to 110 mmHg. The lumbosacral plexus is formed by the ventral rami of about eight spinal nerves. In turn, these nerves provide innervation to the stifle extensors and leg adductors. The sacral plexus runs through the middle renal division parenchyma and exits the pelvis via the ischiadic foramen.

Record clinical tumor size as 022 (22 mm) as that is the largest tumor size that was recorded before treatment occurred diabetes mellitus type 2 home remedies 60 caps diabecon sale, since the pathologic resection is after the neoadjuvant therapy diabetes type 1 2 year old cheap diabecon online mastercard. Record the tumor size as one mm less than stated when tumor size is reported as "less than x mm or less than x cm" i diabetes type 1 cookbook discount 60 caps diabecon visa. For example, if size is < 10 mm, code size as 009 Often measurements are given in centimeters and must be converted to millimeters, such as < 1 cm (<10 mm), which is coded as 009; or < 2 cm (<20 mm), which is coded as 019 Code 001 when stated as less than 1 mm iii. Record the tumor size as one mm more than stated when tumor size is reported as "more than x mm" or "more than x cm" i. For example, if size is > 10 mm, code size as 011 Often measurements are given in centimeters and must be converted to millimeters such as: > 1 cm (> 10 mm), code as 011; or > 2 cm (> 20 mm), code as 021 Code 989 when described as anything greater than 989 mm (98. Round decimals: Round the tumor size when it is described in fractions (decimals) of millimeters as follows Note 1: Record tumor size as 001 (do not round down to 000) when the largest dimension of a tumor is less than 1 millimeter (greater than 0 mm and less than 1 mm). When tumor size is greater than 1 millimeter, round tenths of millimeters in the 1-4 range down to the nearest whole millimeter and round tenths of millimeters in the 5-9 range up to the nearest whole millimeter. Do not round tumor size expressed in centimeters to the nearest whole centimeter; rather, convert the measurement to millimeters by moving the decimal point one space to the right 7. Priority of imaging/radiographic techniques: Information on size from imaging/radiographic techniques can be used to code clinical size when there is no more specific size information from a biopsy or operative (surgical exploration) report. Tumor size discrepancies among imaging and radiographic reports: Record the largest size in the record regardless of the imaging technique, when there is a difference in reported tumor size among imaging and radiographic techniques, unless the physician specifies the imaging that is most accurate. Note: An incisional biopsy that removed the whole tumor is actually an excisional biopsy. However, when the tumor is described as a "cystic mass or polypoid mass," and only the size of the entire mass is given, code the size of the entire mass, since the cysts or polyps are part of the tumor itself. Assign tumor size code 999 when size is unknown Document the information in the appropriate text field of the abstract to support the clinical tumor size as coded. Pathologic classification includes operative and pathological findings of the resected specimens, before initiation of adjuvant treatment. Pathologic tumor size is an important prognostic indicator and valuable for clinical practice and research on surgically treated patients for most cancers. Code 000 001 002-988 989 990 998 Description No mass/tumor found 1 mm or described as less than 1 mm (0. Convert to millimeters from centimeters when size of tumor is measured in centimeters (cm). Often measurements are given in centimeters and must be converted to millimeters, such as < 1 cm, code as 009; or < 2 cm, code as 019. Code pathologic tumor size to 999 for unknown when there is no excisional biopsy or tumor resection Record the size of the tumor. Record the size of the invasive component, even if it is smaller, when both an in situ and an invasive component are present and the invasive component is measured. Record the size of the entire tumor from the surgical report or pathology report when the size of the invasive component is not given Example: A breast tumor with infiltrating duct carcinoma with extensive in situ component; total size 2. Record the size of the primary tumor, including contiguous tumor tissue extension, at the time of diagnosis Code the largest size of the primary tumor measured on the surgical resection specimen when surgery is administered as part of the first definitive treatment Note: this includes pathologic tumor size from surgery when there is neoadjuvant therapy. Use final diagnosis, microscopic, or gross examination, in that order, when no synoptic report is available b. Record the tumor size as one mm less than stated when tumor size is reported as "less than x mm" or "less than x cm" Example: size is < 10 mm code size as 009. Often measurements are given in centimeters and must be converted to millimeters, such as < 1 cm, code as 009; or < 2 cm, code as 019. Often measurements are given in centimeters and must be converted to millimeters, such as > 1 cm, code as 011; or > 2 cm, code as 021. Record "between" tumor sizes as the midpoint between the two measurements when tumor size is reported to be between two sizes; i. Round decimals: Round the tumor size only if it is described in fractions of millimeters. Note 1: Record tumor size as 001 (do not round down to 000) when the largest dimension of a tumor is less than 1 millimeter (between 0. Do not round tumor size expressed in centimeters to the nearest whole centimeter; rather, convert the measurement to millimeters by moving the decimal point one space to the right 11. Always code the size of the primary tumor, not the size of the polyp, ulcer, cyst, or distant metastasis. However, when the tumor is described as a "cystic mass" or "polypoid mass" and only the size of the entire mass is given, code the size of the entire mass, since the cysts or polyps are part of the tumor itself. Record the largest dimension or diameter of tumor, whether it is from an excisional biopsy specimen or the complete resection of the primary tumor Example: Tumor is described as 2. Record the size as stated for purely in situ lesions Disregard microscopic residual or positive surgical margins when coding tumor size. Do not add the size of pieces or chips together to create a whole; they may not be from the same location, or they may represent only a very small portion of a large tumor. However, when the pathologist states an aggregate or composite size (determined by fitting the tumor pieces together and measuring the total size), record that size. Multifocal/multicentric tumors: Code the size of the largest invasive tumor, or the largest in situ tumor if all tumors are in situ, when the tumor is multi-focal or when multiple tumors are reported as a single primary. If not available, code the absence or presence of lymphovascular invasion as described in the medical record. The primary sources of information about lymphovascular invasion are the pathology check lists (synoptic reports) developed by the College of American Pathologists. For cases treated with neoadjuvant (preoperative) therapy, refer to table below to code this field. However, if documentation in the medical record conflicts with this table, code lymphovascular invasion based on the documentation in the medical record. Angiolymphatic invasion Blood vessel invasion Lymph vascular emboli Lymphatic invasion Lymph-vascular invasion Vascular invasion 4. The six Mets at Diagnosis-metastatic sites fields provide information on specific metastatic sites for data analysis. Code 0 1 8 9 Description None; no bone metastases Yes; distant bone metastases Not applicable Unknown whether bone is an involved metastatic site Not documented in patient record Coding Instructions 1. Code information about bone metastases only (discontinuous or distant metastases to bone) identified at the time of diagnosis. Bone involvement may be single or multiple Information about bone involvement may be clinical or pathological Code this field for bone metastases even if the patient had neoadjuvant (preoperative) systemic therapy Code this field for all solid tumor schemas (including Kaposi Sarcoma and Ill-Defined Other [includes unknown primary site]) and the following Hematopoietic schemas i. Indicates that there are no distant (discontinuous) metastases at all Includes a clinical or pathologic statement that there are no bone metastases Includes imaging reports that are negative for bone metastases Indicates that the patient has distant (discontinuous) metastases but bone is not mentioned as an involved site Example: Use code 0 when the patient has metastasis to lung and liver but not bone. Indicates that the patient has distant (discontinuous) metastases and bone is mentioned as an involved site Indicates that bone is the primary site and there are metastases in a different bone or bones 1.

Treatment of the ocular surface inflammation prior to blood sugar fatigue buy diabecon 60 caps with visa plug insertion has been recommended blood glucose 350 cheap diabecon 60caps otc. Acute or chronic infection of the lacrimal canaliculus or lacrimal sac is also a contraindication to diabetes type 1 obesity diabecon 60 caps with amex use of a plug. Complications the most common complication of punctal plugs is spontaneous plug extrusion, which is particularly common with the Freeman-style plugs. Over time, an extrusion rate of 50% has been reported, but many of these extrusions took place after extensive periods of plug residence. More troublesome complications include internal migration of a plug, biofilm formation and infection,59 and pyogenic granuloma formation. Removal of migrated canalicular plugs can be difficult and may require surgery to the nasolacrimal duct system. Summary the extensive literature on the use of punctal plugs in the management of dry eye disease has documented their utility. Several recent reports, however, have suggested that absorption of tears by the nasolacrimal ducts into surrounding tissues and blood vessels may provide a feedback mechanism to the lacrimal gland regulating tear production. Moisture Chamber Spectacles the wearing of moisture-conserving spectacles has for many years been advocated to alleviate ocular discomfort associated with dry eye. However, the level of evidence supporting its efficacy for dry eye treatment has been relatively limited. Tsubota et al, using a sensitive moisture sensor, reported an increase in periocular humidity in subjects wearing such spectacles. There have been several reports with relatively high level of evidence describing the relationship between environmental humidity and dry eye. Korb et al reported that increases in periocular humidity caused a significant increase in thickness of the tear film lipid layer. Contact Lenses Contact lenses may help to protect and hydrate the corneal surface in severe dry eye conditions. Several different contact lens materials and designs have been evaluated, including silicone rubber lenses and gas permeable scleralbearing hard contact lenses with or without fenestration. Among them, a diquafosol eye drop has been favorably evaluated in clinical trials. In animal studies, rebamipide increased the mucin-like substances on the ocular surface of N-acetylcysteine-treated rabbit eyes. A single instillation of ecabet sodium ophthalmic solution elicited a statistically significant increase in tear mucin in dry eye patients. Two percent of the patients taking pilocarpine withdrew from the study because of drug-related side effects. When of autologous origin, they lack antigenicity and contain various epitheliotrophic factors, such as growth factors, neurotrophins, vitamins, immunoglobulins, and extracellular matrix proteins involved in ocular surface maintenance. Biological tear substitutes maintain the morphology and support the proliferation of primary human corneal epithelial cells better than pharmaceutical tear substitutes. To produce serum eye drops and to use them for outpatients, a license by an appropriate national body may be required in certain countries. The protocol used for the production of serum eye drops determines their composition and efficacy. Because of significant variations in patient populations, production and storage regimens, and treatment protocols, the efficacy of serum eye drops in dry eyes has varied substantially between studies. Symptoms improved in 10 out 16 patients, and impression cytological findings improved in 12 out of 25 eyes. Salivary Gland Autotransplantation Salivary submandibular gland transplantation is capable of replacing deficient mucin and the aqueous tear film phase. This procedure requires collaboration between an ophthalmologist and a maxillofacial surgeon. Due to the hypoosmolarity of saliva, compared to tears, excessive salivary tearing can induce a microcystic corneal edema, which is temporary, but can lead to epithelial defects. For this group of patients, such surgery is capable of substantially reducing discomfort, but often has no effect on vision. Regardless of the initiating cause, a vicious circle of inflammation can develop on the ocular surface in dry eye that leads to ocular surface disease. Based on the concept that inflammation is a key component of the pathogenesis of dry eye, the efficacy of a number of anti-inflammatory agents for treatment of dry eye disease has been evaluated in clinical trials and animal models. An increased Schirmer test score was observed in 59% of patients treated with CsA, with 15% of patients having an increase of 10 mm or more. In contrast, only 4% of vehicle-treated patients had this magnitude of change in their Schirmer test scores (P < 0. No CsA was detected in the blood of patients treated with topical CsA for 12 months. Clinical improvement from CsA that was observed in these trials was accompanied by improvement in other disease parameters. Treated eyes had an approximately 200% increase in conjunctival goblet cell density. Clinical Studies Corticosteroids are an effective anti-inflammatory therapy in dry eye disease. Corneal fluorescein staining was negative in 80% of eyes in Group 1 and 60% of eyes in Group 2 after 2 months. The corticosteroid methylprednisolone was noted to preserve corneal epithelial smoothness and barrier function in an experimental murine model of dry eye. Properties of Tetracyclines and Their Derivatives 1) Antibacterial Properties the antimicrobial effect of oral tetracycline treatment analogues (eg, minocycline, doxycline) has previously been discussed by Shine et al,146 Dougherty et al,147 and Ta et al. These include benign conditions (eg, rosacea) and malignant processes (eg, cancer). Minocycline and doxycycline inhibit angiogenesis induced by implanted tumors in rabbit cornea. Well-controlled studies must be performed, at both the laboratory and clinical levels, to investigate this potential. Clinical Applications of Tetracycline 1) Acne Rosacea Rosacea, including its ocular manifestations, is an inflammatory disorder, occurring mainly in adults, with peak severity in the third and fourth decades. Factors that promote angiogenesis include protease-triggered release of angiogenic factors stored in the extracellular matrix, inactivation of endothelial growth factor inhibitors, and release of angiogenic factors from activated macrophages. There are multiple forms of chronic blepharitis, including staphylococcal, seborrheic (alone, mixed seborrheic/staphylococcal, seborrheic with meibomian seborrhea, seborrheic with secondary meibomitis), primary meibomitis, and others, like atopic, psoriatic, and fungal infections. Use of tetracycline in patients with meibomianitis has been shown to decrease lipase production by tetracyclinesensitive as well as resistant strains of staphylococci. This may be due to lipase inhibition by the antibiotic or a direct effect on the ocular flora. A prospective, randomized, double-blind, placebocontrolled, partial crossover trial compared the effect of oxytetracycline to provide symptomatic relief of blepharitis with or without rosacea. Only 25% of the patients with blepharitis without rosacea responded to the antibiotic, whereas 50% responded when both diseases were present. One study also demonstrated a decrease in aqueous tear production that occurred along with clinical improvement.

Bernasconi et al79 also reported on an entire family that became ill after a professional aquarium cleaner poured boiling water on a Palytoxin-encrusted coral fragment diabetes mellitus type 2 honey cheap 60 caps diabecon with mastercard. The cleaner diabetes symptoms when sugar is high discount diabecon 60 caps amex, along with four members of the family elsewhere in the room diabetes symptoms in children type 2 order 60caps diabecon amex, reported to the emergency department complaining of respiratory symptoms. All patients developed a low-grade fever, increased white cell 471 Medical Aspects of Biological Warfare count, and elevated creatine phosphokinase during their hospital stay. The intoxication of other people not directly involved with the aquarium cleaning process strongly suggests extremely high potency of the aerosolized toxic material. Diagnosis Context is key to the clinical diagnosis of the known palytoxin intoxication syndromes. Palytoxin poisoning should be suspected in patients who present with rapid onset of respiratory distress and tonic muscle contractions soon after eating grazing fish species (especially sardines, but also other fish such as herring, anchovies, etc), and especially during warm summer months. Cases have been described only in Caribbean, African coastal, and Indo-Pacific waters. The complication of rhabdomyolysis, with creatine kinase levels peaking at about 24 to 36 hours after symptom onset, would also be an important later clue if the diagnosis has not yet been made. Other palytoxin intoxication syndromes differ from fish poisoning in varying degrees according to the route of exposure: dermal exposure, as with marine aquarium hobbyists, can be expected to produce local and systemic skin manifestations as described above; inhalational exposure near an algal bloom is known to produce respiratory distress and a mild dermatitis, but also fever (in a majority of cases) and conjunctivitis (in a minority). Gastrointestinal symptoms were also reported in a significant minority of inhalational cases, and low-grade fever was reported in most of the aquarium hobbyists. Definitive laboratory identification of palytoxins in seafood can be accomplished with rapid and sensitive hemolysis neutralization assays,82 but the relative rarity of these syndromes does not make the licensing or widespread commercial availability of these tests likely in the foreseeable future. A number of other investiga- tional methods of detection (including immunoassays and a fluorescence polarization) have been described in the literature. For exposures restricted to contact with intact skin/mucosa only (eg, beachgoers exposed to algal blooms), experience indicates that nonsteroidal antiinflammatory drugs are effective and that the condition is self-limited. Supportive care and the amelioration of symptoms are then the basis of treatment, with aggressive hydration via infusion of intravenous fluids being the primacy focus in significant intoxications where avoidance of rhabdomyolysis-induced renal failure is the goal. Palytoxin(s) have been implicated in a number of human fatalities involving ingestion of tropical fishes, with one author estimating a case fatality rate-based on an admittedly limited number of cases-of 45%. Given the apparent potency of exposures to aerosols, as well as the lethality associated with ingestions, palytoxins seem to have potential as bioterrorism agents. The large numbers sickened (more than 200 individuals) in the 2005 Genoa event (20% of whom were hospitalized) indicate these possibilities. Although the toxins may be highly lethal, extracting and weaponizing them is relatively difficult because of the relatively small amounts of toxins typically produced by the source organ472 isms. Such toxins may be more suitable for causing incapacitation or death among small groups or for assassinations. Brevetoxins inhibit sodium channel inactivation, leading to depolarization of membranes. Although naturally acquired cases typically resolve spontaneously in 1 to 3 days, patients should be carefully observed and may require aggressive airway management. Domoic acid is a neuroexcitatory amino acid that kills cells within the central nervous system, particularly in the hippocampus, which is associated with learning and memory. Patients with domoic acid intoxication develop gastrointestinal symptoms and neurological symptoms, including anterograde memory loss and myoclonus. Medical management of domoic acid intoxications includes monitoring of hemodynamic status and pharmacological treatment of seizures. Palytoxins derive from both dinoflagellate blooms or from the polyps of soft corals of the genus Palythoa. Oral intoxication can lead to malaise, vomiting and diarrhea, a bitter or metallic taste in the mouth, muscle aches and cramps, numbness or tingling in the extremities, bradycardia, and dyspnea. Inhalation exposure can lead to respiratory symptoms such as fever, sore throat, cough, dyspnea, headache, nausea/ vomiting, rhinorrhea, lacrimation, and dermatitis. An underappreciated exposure mechanism is through the home aquarium trade, whereby several incidences of inhalational or dermal intoxication have occurred through the handling or disinfection of Palythoa polyps. Treatment of palytoxin intoxication, which is nonspecific, is based on the route of exposure. The apparent extreme aerosol toxicity of palytoxins, as suggested by several incidences of beachgoers being intoxicated during near-shore blooms of O ovata, makes it critical for further investigation of the aerosol toxicology of these compounds.

If prone was not tolerated, they suggested a lateral decubitus position, and avoided this in the 1 hour after a meal. Found that improved SpO2 in 1 hour to > 95% was associated with a lower risk of intubation. Many still intubated- often rapidly after prone attempt (perhaps done too late) jamanetwork. Factors associated with death (multivariate analysis) were age > 65, comorbidities as previously reported. More seriously ill patients (on vent) or > 70yoa did not have the same likelihood of improvement.

Under the new circumstances diabetes mellitus definition in medical order diabecon cheap online, the odds are that most of human life and most of human lives will be spent agonizing about the choice of goals diabetes prevention trial metformin generic diabecon 60 caps with mastercard, rather than finding the means to diabetes in dogs natural diet 60 caps diabecon with visa the ends which do not call for reflection. There are more - pain fully more - possibilities than any individual life, however long, adventurous and industrious, can attempt to explore, let alone to adopt. It is the infinity of chances that has filled the place left empty in the wake of the disappearing act of the Supreme Office. In such a world, though, there is not much room either for the benign and caring Elder Brother who could be trusted and relied upon when it came to decide which 62 Individuality things were worth doing or having and who could be counted on to protect his kid brother against the bullies who stood in the way of getting them; and so the utopias of the good society have stopped being written as well. It is up to the individual to find out what she or he is capable of doing, to stretch that capacity to the utmost, and to pick the ends to which that capacity could be applied best - that is, to the greatest conceivable satisfaction. Few defeats are final, few if any mishaps irreversible; yet no victory is ultimate either. For the possibilities to remain infinite, none may be allowed to petrify into everlasting reality. The awareness that the game goes on, that much is still going to happen and the inventory of wonders which life may offer is far from closed, is richly safisfying and pleasurable. The suspicion that nothing which has been already tested and appropriated is insured against decay and guaranteed to last is, though, the proverbial fly in the barrelful of tasty ointment. Life is bound to navigate between the two, and no sailor can boast of having found a safe, let alone risk-free, itinerary. Individuality 63 the world full of possibilities is like a buffet table set with mouth-watering dishes, too numerous for the keenest of eaters to hope to taste them all. The diners are consumers, and the most taxing and irritating of the challenges consumers confront is the need to establish priorities: the necessity to forsake some unex plored options and to leave them unexplored. As Marina Bianchi put it in a collective study produced by economists with the sellers of con sumer goods in mind, in the case of the consumer, the objective function. Hypothetically consumers, but not firms, may never - or never be found to - err 1 0. If there are no wrong moves, there is nothing to distin guish a move as a better one, and so nothing to recognize the right move among its many alternatives - neither before nor after the move has been made. That the danger of error is not on the cards is a mixed blessing - a doubtful j oy, to be sure, since the price it com mands is one of perpetual uncertainty and of a desire never likely to be satiated. This is good news, a promise of staying in business, for the sellers, but for the buyers an assurance of staying in agony. Heavy, Fordist-style capitalism was the world of law-givers, rou tine-designers and supervisors, the world of other-directed men and women pursuing fixed-by-others ends in a fixed-by-others fash ion. For this reason it was also the world of authorities: of leaders who know better and of teachers who tell you how to proceed better than you do. Light, consumer-friendly capitalism did not abolish the law proffering authorities, nor did it make them redundant. Unlike error, the truth is one, and may be acknowledged as the truth (that is, given the right to declare all alternatives to itself erroneous) only in so far as it is unique. When the authorities are many, they tend to cancel each other out, and the sole effective authority in the field is one who must choose between them. Authorities no longer command; they ingratiate themselves with the chooser; they tempt and seduce. There is, of course, no shortage of those who claim to be in the know, and quite a few of them have numerous followers ready to agree. Leaders demand and expect discipline; counsellors may at best count on the willingness to listen and pay heed. That willingness they must first earn by currying favour with the would-be listeners. Counsellors, on the contrary, are wary of ever step ping beyond the closed area of the private. Illnesses are individual, and so is the therapy; worries are private, and so are the means to fight them off. The counsels which the counsellors supply refer to life-politics, not to Politics with a capital P; they refer to what the counselled persons might do by themselves and for themselves, each one for himself or herself - not to what they all together might achieve for each one of them, once they j oin forces. There is little to be gained from doing the job for others, and it would divert your attention from the j ob no one can do but you. At the end of the counselling session the counselled persons are as alone as before the session started. If anything, they are reinforced in their loneliness: their hunch that they would be abandoned to their own devices has been corroborated and turned into near-certainty. Whatever the content of the advice, it referred to things which the counselled persons must do themselves, accepting full responsibility for doing them properly and blaming no one for the unpleasant consequences which could be ascribed only to their own error or neglect. Providing that the nature of troubles is such as can be tackled only by individuals on their own and coped with by individual efforts, what the advice-seeking people need (or believe they need) is an example of how other men or women, facing a similar trouble, go about the task. To sustain and reinforce the postmodern amour de soi, she invokes (alongside the consumer tendency to self-identify through possessions) the memory of a very pre-postmodern - in fact more pre-modern than modern instinct of workmanship: the product of my work is as good as Individuality 67 (and no better than) the skills, attention and care which I invest in its production. Whatever the results, I have no one else to praise (or to blame, as the case may be). The obverse side of the message is also unambiguous, even if not spelled out with similar clarity: you owe your body thought and care, and if you neglect that duty you should feel guilty and ashamed. But the redemption of sins is in the hands of the sinner, and in his or her hands alone. Let me repeat after Hilary Redner: saying all this, Fonda does not act as authority (law-giver, norm-setter, preacher or teacher). In general, however, one cannot be sure of the direction in which the causal link between the willingness to follow the example and the author ity of the exemplary person works. Boorstin wittily, though not at all j okingly, observed (in the Image, 1 96 1), the celebrity is a person who is known for his well-knownness, while a best-seller is a book which sold well because it was selling well. Authority expands the ranks of the followers, but in the world of uncertain and chronically underdetermined ends it is the number of the followers that makes - that is - the authority. Whatever may be the case, in the example-authority couple it is the example part that matters most and is most in demand. The authority of the person sharing her or his life-story may help view ers watch the example attentively and add a few thousand to the ratings. As mentioned before, nam ing the trouble is itself a daunting task, while without attaching a name to the feeling of unease or unhappiness there is no hope for cure. Whatever is to be named, including the Individuality 69 most secret, personal and intimate sentiments, is properly named only if the names chosen have public currency, only if they belong to language which can be interpersonally shared and public and are understood by people who communicate in that language. This is, by itself, a gain of the utmost importance - but there are yet more gains. In chat-shows words and phrases referring to the experience deemed intimate and so unfit to be talked about are uttered in public - and to universal approval, amusement and applause. They render the unspeakable speak able, the shameful decent, and transform the ugly secret into a matter of pride. Thanks to chat-shows, I may speak from now on openly about things which I thought (mistakenly, as I see it now) were disgraceful and disgracing and so bound to be kept secret and suffered in silence. Since my confession is no more secret, I gain more than j ust the comfort of the absolution: I need no longer feel ashamed or wary of being frowned upon, rebuked for impudence and ostracized.
