Miscellaneous Q: Is there a difference in success rate with placement of an implant in a clean versus a sterile conditionfi In or der to attain a similar high rate of osseointegration, implant surgery can be performed under both sterile and clean conditions. The interface between an implant and the epitheilum consists of hemides mosomes and basal lamina. The biologic width is 3 to 4 mm with 2 mm of epithelial attachment and 1 mm of connective tissue attachment. Buddula et al74 did a retrospective study and found that implants placed in pa tients with head and neck cancer who had received radiation treatment had a greater risk of failure compared with those placed in nonirradiated bone. The study also found that implants placed in the maxilla had a greater chance of failure than those placed in the mandible. Lastly, implants placed in the posterior region had a greater likelihood of failure than those placed anteriorly. A cone beam computed to mography scan, preferably with high resolution and a small feld of view, should be ordered to assess how sclerotic the bone is and the extent of the changes. The problem with sclerotic bone is the decreased vascularity, which may compromise healing and osseointegration.

Penicillin, 20 million units intrave­ nus and diphtheria to xoids vaccine) is administered as two nously daily in divided doses, is given to all patients-even doses 4-6 weeks apart, with a third dose 6-12months later. Booster doses are given every lO years or at the time of major injury if it occurs more than 5 years. A single dose of Tdap is preferred to Td for High mortality rates are associated with a short incubation wound prophylaxis if the patient has not been previously period, early onset of convulsions, and delay in treatment.

Treatment involves excision with margins (lumpec to my) and radiation therapy to the breast. Treatment with tamox ifen may be considered, but close follow-up and observation are indicated. Complete axillary node dissection is warranted only in sentinel-node or clinically node tu mors. Tamoxifen re duces the risk of recurrence by approximately 40%; chemotherapy reduces the risk by approximately 25%. Aromatase inhibi to rs prevent the conversion of adrenal androgens in to estrogens by targeting aromatase en zymes in muscle and fat. Hormonal therapies such as If patients progress or are hormone recep to r, treat with chemotherapy. Eighty-seven percent of all cases of lung cancer are related to smoking, with the risk significantly higher in patients who have been exposed to asbes to s and who also smoke. Lung cancer presents with weight loss, cough, hemoptysis, fatigue, recurrent bronchitis, and chest pain. Other paraneoplastic syndromes associated with thymoma include pure red cell aplasia. Lesions progress as follows: leuko plakia > erythroplakia > dysplasia > carcinoma in situ > invasive carci noma. The highest risk of morbidity and mortality associated with head and neck cancer results from local extension rather than from metastasis. Refer to the Endocrinology chapter for a more detailed discussion of thyroid cancer. Working in coal min ing and in nickel, rubber, and timber processing are additional risk fac to rs. Most are hormonally inert, but some can secrete ex cessive sero to nin, prostaglandins, and kinins. For further detail, refer to the section on carcinoid tumors and syndrome in the Endocrinology chapter.

Biopsy of a renal mass is gen erally not done given the risk of seeding the tumor. Other risk fac to rs include prior testicular cancer, Klinefelter’s syndrome, and a family his to ry. In patients who have Observation, chemotherapy, and radiation therapy are all appropriate if metastatic testicular cancer at the patient is felt to be at high risk for retroperi to neal lymph node the time of diagnosis, the metastasis. Risks include unopposed estrogen (either endoge nous or exogenous), obesity (due to ^ aromatization of androgens to estro gens), and high levels of animal fat in diet. Ge netic risk fac to rs include familial retinoblas to ma, which is associated with os teosarcoma. Subtypes are as follows: Bone sarcomas: Osteosarcoma: Affects long bones in children and adolescents; associ ated with Paget’s disease in the elderly. If the tumor is located below the dentate line, drainage is to the inguinal lymph nodes, which are the first site of metastasis. If the tumor is located above the den tate line, drainage is to the paravertebral and perirectal nodes. Subtypes are as follows: Lung Breast Gliomas: Most common; range from low grade to high grade (glioblas Skin (melanoma) to ma multiforme). Lep to meningeal Chemotherapy has limited utility in malignant gliomas, although oligo metastases are most common dendrogliomas are highly chemosensitive (associated with chromosome 1p and 19q loss). Brain Metastases Occur in 15% of patients with solid tumors, most commonly lung and breast cancer. Highly re frac to ry to conventional therapy; most often symp to matic (night sweats, weight loss, bone pain, fevers, cy to penias). Treatment has changed dramati cally since the introduction of imatinib (see below). Fatigue Usually multifac to rial and includes anorexia, anemia, depression, infec tion, hypoxia, deconditioning, and hypogonadism. As with other illness, symp to ms suggest categories that can then be further clarified. In general, there are no objective labora to ry tests for psychiatric diagnostic clarification, so a careful his to ry is essential. Psychotic disorders are treated with antipsychotics; anxiety disor ders are treated with anxiolytic agents. Mood disorders are treated with an tidepressants or mood stabilizers, depending on unipolarity or bipolarity. For these syndromes, treatment generally involves medication with > 1 category, targeting each symp to m separately.

Age of onset is mostly in the late teens or 20s for men and in the 20s–30s for women; the male- to -female ratio is 1:1. Olanzapine and several other Depression with psychotic features: Patients have psychotic symp to ms atypical antipsychotics can that occur only during depressive episodes, and the depressive symp to ms can occur without psychotic symp to ms. Neuropsychological testing can be helpful in clarifying the diagnosis but often is not indicated. How ever, atypicals are much more expensive and can cause significant weight gain. Group therapy can provide a forum for reality checks if patients can to ler ate them. Patients newly diagnosed with Maintenance treatment: Titrate to the lowest effective dose of antipsy chotic agent to maintain stability. Group therapy and structured day pro schizophrenia (“first break”) grams provide safety, socialization skills, and reality checks. Delusional Disorder Patients have a fixed false belief (delusion) that is nonbizarre. Age of onset is from the mid-20s to the 90s; the male- to -female ratio is roughly 1:1. Low-dose common than schizophrenia atypical antipsychotics may be helpful, Do not pretend that the delusion is true, but do not argue with patients to and is less responsive to prove it false. Optimal treatment varies from patient to patient but usually involves combi nations of the following: Pharmacologic substitutes: Replace the substance of abuse with a longer acting and less addictive pharmacologic equivalent. Examples include methadone for heroin, chlordiazepoxide (Librium) for alcohol, and clon azepam for short-acting benzodiazepines.
