Sickle cell anemia- clinical manifestations in 100 patients and review of the literature.

The clinical and hematological features of 100 patients with sickle cell anemia are reviewed. The heart was enlarged and a murmur was heard in nearly 80 percent of patients. Pneumonia and pulmonary infarction occurred in 43 percent and 12 percent of patients, respectively. Musculoskeletal involvement included the hand-foot syndrome (15 percent), leg ulcers (55 percent), aseptic necrosis ofbone (11 percent), and osteomyelitis (4 percent). Symptoms and signs related to the gastrointestinal system included jaundice (55 percent), hepatomegaly (50 percent), splenomegaly (23 percent), hepatitis (11 percent) and gallstones (9 percent). Three patients underwent cholecystectomy and three patients had their spleens removed. Pyelonephritis occurred in 17 patients, priapism in five and hematuria in seven. Nineteen women had 39 pregnancies, of which 35 resulted in the birth of healthy infants. At least 328 painful crises occurred in 73 patients. There were also 13 hemolytic crises, eight sequestration crises, and five aplastic crises. A trail of alkali therapy in 33 crises in children failed to produce beneficial effects greater than hydration and analgesics alone as used in the control group. Laboratory findings in the 100 patients were comparable to those previously reported in the literature. The renal concentrating defect in most patients was confirmed. There were six deaths: hepatic coma secondary to post-transfusion hepatitis, thrombosis of inferior vena cava, congestive heart failure, exsanguination from erosion of the pancreaticoduodenal artery, extensive bronchopneumonia, and pulmonary infarction.

Middle Eastern intestinal lymphoma: report of a case and review of the literature.

A 20-year-old Persian man with Middle Eastern lymphoma is described, and 84 additional cases from the literature are reviewed. Basically, the disease is a malignant lymphoma which involves the upper small intestine (duodenum and proximal jejunum). It is associated with clubbing of the fingers, abdominal pain, weight loss, diarrhea, vomiting, and malabsorption, and frequently occurs in a younger age group than "Western Hemisphere" intestinal lymphoma. Some patients also have alpha heavy chain disease. The sex ratio is equal, and the disease occurs only in Middle Eastern and North African Moslems and Jews. Upper gastrointestinal radiographs are frequently diagnostic, and per oral small intestinal biopsy is nearly always diagnostic. Pathologically, the following features are characteristic for Middle Eastern lymphoma: partial or total villous atrophy with only mildly abnormal surface epithelium, sparsity of crypts, lymphatic dilatation, and infiltration of lamina propria by pleomorphic mononuclear cells which pepetrate the muscularis mucosa. The etiology and pathogenesis of this disease are unknown, but several hypotheses are discussed. Treatment by a variety of modalities is far from satisfactory, and the prognosis is much poorer than that observed in patients with the "Western" form of intestinal lymphoma. Other differences between Middle Eastern lymphoma and Western lymphoma are described in detail,

Misleading acute hypercalcemia due to hyperlipidemia: a method-dependent error.

OBJECTIVE: To report a case of artifactual hypercalcemia in a patient with hyperlipidemia. METHODS: We present clinical data and laboratory findings in a 33-year-old woman with generalized fatigue, a recent 5-kg weight loss, and a papular rash on the extremities as well as a history of diabetes and hypertension. RESULTS: Physical examination revealed an obese patient with eruptive xanthomas and lipemia retinalis. Laboratory tests showed hyperlipidemia, hypercalcemia (serum calcium measured by spectrophotometry), anemia, hyperproteinemia, hyperuricemia, and hyperbilirubinemia. After 4 days of a low-fat, low-cholesterol diet and gemfibrozil therapy, the serum triglyceride level decreased, and the serum calcium concentration returned to normal. CONCLUSION: In patients with hypercalcemia without an obvious cause, a spurious measurement should be considered.

Thyroid carcinoma in single cold nodules and in cold nodules of multinodular goiters.

OBJECTIVE: To examine the frequency of malignant growth in a nonfunctioning solitary thyroid nodule (SN) and in multinodular goiter (MNG). METHODS: We performed fine-needle aspiration biopsy (FNAB) of cold nodules in 154 patients. Eight patients with unsatisfactory FNAB specimens were excluded from the study. Of the remaining 146 patients, 95 (89 women and 6 men) had MNG. The other 51 patients (46 women and 5 men) had SN. The overall age range was 25 to 86 years (mean, 52). RESULTS: Of the 95 patients with MNG, 16 had abnormal cytologic findings and underwent surgical excision. Of these 16 patients, 12 had thyroid cancer (6 papillary, 3 follicular, and 3 Hürthle cell). Of the 51 patients with SN, 8 had suspicious cytologic findings, and 5 had surgical histologic evidence of thyroid cancer (3 papillary and 2 follicular). Four patients with papillary thyroid cancer (three from the MNG group and one from the SN group) had a history of exposure to neck irradiation. After exclusion of the patients with a history of neck irradiation, the rate of malignant involvement in cold nodules in the MNG group was 9.78%, in comparison with 8% in the group with SN (P = 0.89). Within the MNG group, 25% of the thyroid malignant lesions were of the Hürthle cell type. CONCLUSION: Multinodularity of a goiter should no longer be considered an indicator of probable benign disease. In the assessment of all thyroid nodules, both SN and those in MNG, a thyroid scan can be helpful, and it should be followed by FNAB and cytopathologic examination of any nonfunctioning lesions. The incidence of malignant involvement in cold nodules of MNG does not differ significantly from that found in SN.

Pig organs for transplantation into humans: a Jewish view.

In view of the shortage of human organs for transplantation, intense interest has focused on the use of pig organs. Although the early rejection of pig organs by a human recipient has not yet been overcome, scientists are actively seeking to solve this problem. If and when xenotransplantation from pigs or other animals becomes scientifically feasible, Judaism will look with favor upon this procedure to prolong or save the life of a human being who is ill or dying from organ failure. Although Jewish law forbids Jews to raise or eat pigs, no such prohibition exists for the use of pigs to cure human illness or to save human lives by xenotransplantation.

Maternal/fetal rights: two views.

The autonomy of a pregnant woman is seriously compromised if she is pressured, threatened, or forced to submit to medical or surgical treatment to which she does not consent. The missionary zeal of physicians, judges, and society to save the at-risk fetus at times violates the competent woman's right to make decisions about the integrity of her body. All avenues must be explored to preserve the health of the fetus, but at the same time, the mother's need for self-determination must be respected. Inevitably, clinical emergencies requiring a choice between the life of the fetus and that of the mother will arise. In crisis situations the pregnant woman has a right to choose.
