ABSTRACT Background: The World Health Organization (WHO) estimates that about 2 billion individuals or about 40% of the world’s population suffer from anemia. The population groups with the highest prevalence of anemia are: pregnant women and the elderly (about 50%), infants and children 1 to 2 years (48%), school children (40%), non-pregnant women (35%), and preschoolers (25%). Methods: The study was conducted at MediCiti Institute of Medical Sciences. 1007 children were screened clinically and their blood samples collected and analyzed by hemocue instrument. A complete physical examination was done for all these children. Results: The maximum number of subjects belongs to the nine year old category. Boys constituted 46% of the study population while girls constituted 54% of the study population. Anemia is more prevalent in female subjects than males. In the present study, clinical pallor was present in 16.48% of the subjects. In specific, conjunctival pallor was noted in 9.43%, generalized pallor of skin noted in 4.96% and palmar crease pallor was noted in 1.88% of subjects. The sensitivity and specificity of clinical pallor in diagnosing anemia is 94.02% and 93.71% respectively. The sensitivity and specificity of palmar pallor in diagnosing severe anemia is 100% and 98.21% respectively. Conclusions: The clinical finding of pallor in a child is a reliable indicator of anemia. The presence of clinical pallor in any of the body sites (conjunctival pallor, skin pallor, palmar pallor) is a reliable indicator of anemia. The presence of palmar crease pallor is a good indicator of severe anemia in children. By effective implementation of mid-day meal scheme, the incidence of anemia could be brought down effectively. Keywords: Anemia, Children, Clinical pallor, Palmar crease pallor INTRODUCTION study conducted by the Nutrition Foundation of India (1999), including 520 urban and 185 adolescent girls The World Health Organization (WHO) estimates that (aged 11- 19 years), nearly 17% of the rural and 9.6% of about 2 billion individuals or about 40% of the world’s the urban adolescent girls had Hemoglobin (Hb) levels population suffer from anemia. The population groups <10g/dl.5 with the highest prevalence of anemia are: pregnant women and the elderly (about 50%), infants and children This study was conducted to identify clinical pallor in 1 to 2 years (48%), school children (40%), non-pregnant school children between 6-11 years and to correlate with women (35%), and pre-schoolers (25%).1-3 the blood hemoglobin levels, in the rural district of Medchal.

    242 POST-GRADUATE MEDICAL JOURNAL August, 1938 Postgrad Med J: first published as 10.1136/pgmj.14.154.242 on 1 August 1938. Downloaded from SOME REMARKS ON DIFFERENTIAL DIAGNOSIS OF BLOOD DISEASES. By A. PINEY, M.D., M.R.C.P. (Assistant Physician, St. Mary's Hospital for Women and Children.) Differential diagnosis of blood diseases has been discussed time and again, but, as a rule, blood-pictures, rather than clinical features, have been taken into account, so that the impression has become widespread that the whole problem is one for the laboratory, rather than for the bed-side. It is obvious, however, that the first steps in diagnosis must be based on clinical signs and symptoms. In this paper, there- fore, certain outstanding clinical features of blood diseases, and various rather puzzling syndromes will be described. The outstanding external sign that leads the practitioner to consider the possi- bility of a blood disease is pallor, which is not quite so simple a state as is often supposed. It is, of course, well known that cutaneous pallor is not an infallible sign of anaemia, but it is often presumed that well-coloured mucous membranes are fairly good evidence that anaemia is not present. This is not necessarily true. The conjunctive may be bright pink in spite of anaemia, because mild inflammationProtected by copyright. may be present, masking the pallor. This is quite frequently due to irritation by eyelash dyes. Similarly, the finger-nails, which used to serve as a reliable index of pallor, are now found disguised with coloured varnish.

Kim, MD, MPH This is the case of a previously healthy 15-month-old girl who initially abstract presented to her primary pediatrician with a 2-week history of intermittent periorbital edema. The edema had improved by the time of the visit, and a urine specimen was unable to be obtained in the clinic. A routine fingerstick demonstrated anemia to 8.8 mg/dL, so the patient was started on ferrous sulfate. She then returned to the emergency department 1 month later with severe periorbital edema and pallor but no other significant symptoms. On physical examination, she was tachycardic with striking periorbital edema and an otherwise normal physical examination. She was noted to have a severe microcytic anemia (hemoglobin of 3.9 mg/dL and mean corpuscular Mattel Children’s Hospital and University of California, Los Angeles, Los Angeles, California volume of 53.1 fL) and hypoalbuminemia (albumin of 1.9 g/dL and total protein of 3.3 g/dL).

Received: 12 October 2012; in revised form: 24 October 2012 / Accepted: 26 October 2012 / Published: 31 October 2012 Abstract: Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are retroviruses with global impact on the health of domestic cats. The two viruses differ in their potential to cause disease. FeLV is more pathogenic, and was long considered to be responsible for more clinical syndromes than any other agent in cats. FeLV can cause tumors (mainly lymphoma), bone marrow suppression syndromes (mainly anemia), and lead to secondary infectious diseases caused by suppressive effects of the virus on bone marrow and the immune system. Today, FeLV is less commonly diagnosed than in the previous 20 years; prevalence has been decreasing in most countries. However, FeLV importance may be underestimated as it has been shown that regressively infected cats (that are negative in routinely used FeLV tests) also can develop clinical signs. FIV can cause an acquired immunodeficiency syndrome that increases the risk of opportunistic infections, neurological diseases, and tumors. In most naturally infected cats, however, FIV itself does not cause severe clinical signs, and FIV-infected cats may live many years without any health problems. This article provides a review of clinical syndromes in progressively and regressively FeLV-infected cats as well as in FIV-infected cats.
