Pyloromyotomy of Ramstedt: experience of a nonspecialized centre

In a general hospital over a period of 6 years 57 infants with congenital hypertrophic stenosis underwent a Ramstedt pylorotomy. In most cases a surgical resident-in-training performed the operation under the direct supervision of a general surgeon. There were no complications of anesthesia, no deaths and no substantial morbidity. The majority of infants left the hospital within 48 hours. The results in this series compared favourably with those reported from more specialized centres.     

Impact of pediatricians' attire on children and parents

To evaluate perceptions of a pediatrician's attire, 50 children and parents in an outpatient facility were shown five photographs of a female or a male physician dressed differently (formal to informal). A list of positive and negative attributes was presented to the parents and children who were to match each picture to the attributes. Parents had a strong positive preference for the formally dressed female (short white coat and skirt), and the formally dressed male (short white coat and tie). More than 50% of the parents least preferred the most informal attire. Children had no clear preferences for males and preferred the female in the blouse and skirt. Children assigned negative attributes to informal attire but not to the same degree as did their parents. This study demonstrates that parents have stronger preferences than do their children. Although children had no strong positive preferences, they may feel negatively about informal attire.     

Partial reversal of the hypogonadotropic hypogonadism of obese men by administration of corticosuppressive doses of dexamethasone

Obese men have hyperestrogenemia-induced hypogonadotropic hypogonadism (HHG), due, we believe, to increased rarmatization of adrenal androgens by the increased bulk of aromatase-containing adipose tissue. We studied the effects of corticosuppressive doses of dexamethasone (D) on 24-h mean plasma total and free estradiol (E2), estrone (E1), LH, FSH, total and free testosterone, delta 4-androstenedione (delta 4), and sex-hormone-binding globulin (SHBG) in nine obese men and five normal-weight controls. In the obese men, the following hormones fell: E2 [59 +/- 19 to 39 +/- 11 pg/ml (P less than 0.01)], E1 [93 +/- 41 to 50 +/- 25 pg/ml; (P less than 0.01)], delta 4-androstenedione [120 +/- 80 to 55 +/- 27 ng/dl; (P less than 0.02)]; free E2 [1.6 +/- 0.4 to 1.1 +/- 0.2 pg/ml; (P less than 0.01)], SHBG [12.8 +/- 5.3 to 8.2 +/- 3 nM/l; (P less than 0.04)]. FSH rose from 4.8 +/- 3.2 to 7.6 +/- 4.2 miu/ml (P less than 0.01). LH, total and free testosterone showed no significant change. In the nonobese men, there were decreases in total E2 [(34 +/- 6.8 to 25 +/- 10 pg/ml; P less than 0.04)], SHBG [16.8 +/- 7.5 to 10.4 +/- 2.0 nM/l: P less than .05.], free E2 [0.9 +/- 0.2 to 0.7 +/- 0.3 pg/ml: P less than 0.05], delta 4 [91.4 +/- 3.6 to 33.4 +/- 16.7 ng/dl; P less than .01] and total T [492 +/- 44 to 393 +/- 121 ng/dl; P less than 0.04]. There was no significant change in E1, FSH, LH or free T.(ABSTRACT TRUNCATED AT 250 WORDS)     

Transfusion of bone marrow red cells during bone marrow harvests

Large volumes of bone marrow may be required for certain types of autologous bone marrow transplants. The present study was done to determine whether red cells obtained during a bone marrow harvest would be useful in reducing homologous transfusion requirements. A group of patients receiving standard transfusion support during the harvest (group 1) was compared to a group that received processed bone marrow red cells (PBMRBC) (group 2). Using the Cobe 2991 cell processor, 90% of the harvested bone marrow red cells were extracted and transfused during the procedure. Group 2 received a median of 1500 ml of blood processed from the bone marrow or 413 ml (volume of marrow processed x hematocrit) of red cells. Infusion of the PBMRBC reduced the homologous transfusion requirement from 6.5 units to 3.0 units (p = 0.02). In addition, group 1 had a 20% decrease in hematocrit following transfusion compared to the pre-harvest hematocrit, as opposed to an 8% decrease in group 2 (p = 0.02). This study indicates that PBMRBC can reduce the homologous transfusion requirements during an autologous bone marrow harvest.     

Term delivery in a woman with severe congenital neutropenia, treated with growth colony stimulating factor

The patient was diagnosed in childhood as having severe congenital neutropenia and had recurrent admissions with severe infections. In 1987, prior to getting married, she was sterilized. She continued to require i.v. antibiotics when she contracted a severe infection. On one occasion, she was treated with growth colony stimulating factor (G- CSF). Her increased neutrophil count was sustained following this treatment. In June 1993, she wished to start a family and underwent in- vitro fertilization (IVF) treatment. G-CSF was given prior to oocyte retrieval. She conceived on her first cycle and an ultrasound scan revealed a singleton pregnancy. Throughout the course of the pregnancy, her white cell count was monitored closely and remained at <1.0x10(9)/l. The pregnancy progressed uneventfully and at 37 weeks gestation she was admitted for G-CSF injections. At 38 weeks she was delivered of a boy weighing 3350 g, by elective Caesarean section. His white cell count was normal. This is the first case of G-CSF being used before conception and during pregnancy in a patient with congenital neutropenia. It shows that advances in cytokine therapy and close interdisciplinary liaison can lead to a successful outcome and help patients, who would otherwise remain childless, to achieve a family.
