Abruptio placentae:
Diagnosis
(Professional Guide to Diseases (Eighth Edition))
Diagnostic measures for abruptio placentae include observation of clinical features, speculum examination, and ultrasonography to rule out placenta previa. Decreased hemoglobin (Hb) levels and platelet counts support the diagnosis. Periodic assays for fibrin split products aid in monitoring the progression of abruptio placentae and detect the development of DIC.

Introduction: Malignant Neoplasms:
Diagnostic methods
(Professional Guide to Diseases (Eighth Edition))
A thorough medical history and physical examination should precede sophisticated diagnostic procedures. Useful tests for the early detection and staging of tumors include X-ray, endoscopy, isotope scan, computed tomography scan, and magnetic resonance imaging, but the single most important diagnostic tool is a biopsy for direct histologic study of tumor tissue. Biopsy tissue samples can be taken by curettage, fluid aspiration (pleural effusion), fine-needle aspiration biopsy (breast), dermal punch (skin or mouth), endoscopy (rectal polyps), and surgical excision (visceral tumors and nodes).
An important tumor marker, carcinoembryonic antigen (CEA), although not diagnostic by itself, can signal malignancies of the large bowel, stomach, pancreas, lungs, and breasts. CEA titers range from normal (less than 5 ng) to suspicious (5 to 10 ng) to suspect (over 10 ng). CEA serves many valuable purposes:
❑as a baseline during chemotherapy to evaluate the extent of tumor spread
❑to regulate drug dosage
❑to prognosticate after surgery or radiation
❑to detect tumor recurrence.
Although no more specific than CEA, alpha-fetoprotein — a fetal antigen uncommon in adults — can suggest testicular, ovarian, gastric, and hepatocellular cancers. Beta human chorionic gonadotropin may point to testicular cancer or choriocarcinoma. Other commonly used tumor markers include prostate-specific antigen to detect and monitor prostatic cancer, and CA-125, useful for monitoring ovarian, colorectal, and gastric cancers.

Placenta previa:
Diagnosis
(Professional Guide to Diseases (Eighth Edition))
Special diagnostic measures that confirm placenta previa include:
❑ transvaginal ultrasound scanning for placental position
❑ pelvic examination (under a double setup because of the likelihood of hemorrhage), performed only immediately before delivery to confirm the diagnosis. In most cases, only the cervix is visualized.
Digital examination should be deferred in any pregnant woman in the third trimester with vaginal bleeding, until ultrasound rules out placenta previa.

Malignant spinal neoplasms:
Diagnosis
(Professional Guide to Diseases (Eighth Edition))
❑Spinal and lumbosacral magnetic resonance imaging confirm spinal tumor.
❑ X-rays show distortions of the intervertebral foramina; changes in the vertebrae or collapsed areas in the vertebral body; and localized enlargement of the spinal canal, indicating an adjacent block.
❑ Myelography identifies the level of the lesion by outlining it if the tumor is causing partial obstruction; it shows anatomic relationship to the cord and the dura. If obstruction is complete, the injected dye can't flow past the tumor. (This study is dangerous if cord compression is nearly complete because withdrawal or escape of cerebrospinal fluid (CSF) will allow the tumor to exert greater pressure against the cord.)
❑ Radioisotope bone scan demonstrates metastatic invasion of the vertebrae by showing a characteristic increase in osteoblastic activity.
❑ Computed tomography scan shows cord compression and tumor location.
❑ Frozen section biopsy at surgery identifies the tissue type.
❑ Lumbar puncture may be normal, abnormal, or nonspecific. It may show clear yellow CSF as a result of increased protein levels if the flow is completely blocked. If the flow is partially blocked, protein levels rise, but the fluid is only slightly yellow in proportion to the CSF protein level. Cytology of the CSF may show malignant cells of metastatic carcinoma.

Abruptio placentae:
Diagnosis
(Handbook of Diseases)
Diagnostic measures for abruptio placentae include observations of signs and symptoms, pelvic examination (under double setup), and ultrasonography to rule out placenta previa.
CLINICAL TIP: If a clot can be seen by ultrasound just under the placenta, delivery is generally advisable.
Decreased hemoglobin (Hb) levels and platelet counts support the diagnosis. Periodic assays for fibrin split products aid in monitoring the progression of abruptio placentae and detecting the development of DIC.

Lymphomas, malignant:
Diagnosis
(Handbook of Diseases)
A positive diagnosis requires histologic evaluation of biopsied lymph nodes of tonsils, bone marrow, liver, bowel, or skin or of tissue removed during exploratory laparotomy. A biopsy differentiates malignant lymphoma from Hodgkin’s disease.
Other tests include bone and chest X-rays, lymphangiography, a liver and spleen scan, computed tomography scan of the abdomen, and excretory urography. Laboratory tests include a complete blood cell count (which may show anemia), uric acid level (elevated or normal), serum calcium level (elevated if bone lesions are present), serum protein level (normal), and liver function studies.
