New medical standards for Virginia's high school athletes.

Virginia physicians administering preparticipation physicals to high school athletes this fall are using the new, expanded examination form that appears in this issue. Representing multidisciplinary input and incorporating current sports medicine information, the form is designed to identify the student at high risk for injury and to evaluate for a specific sport. After a two-year pilot program conducted by the authors the new form was officially adopted by the Virginia High School League.

Fatal overwhelming postsplenectomy sepsis following autologous splenic transplantation in severe congenital osteopetrosis.

We report a boy with severe congenital osteopetrosis who underwent splenectomy at age 4, with simultaneous transplantation of portions of the spleen into the anterior rectus compartments. Despite demonstrated survival and partial functioning of the splenic implants, the patient died 9 years later from an overwhelming postsplenectomy infection (OPSI). This report suggests that the presence of the amount of retained splenic tissue transplanted in this case after splenectomy ultimately provides relatively ineffective protection against OPSI in congenital osteopetrosis.

Three-day therapy of lower urinary tract infections with nitrofurantoin macrocrystals: a randomized clinical trial.

Forty-nine girls between the ages of 2 and 18 years with a symptomatic urinary tract infection documented by two clean-catch urine cultures completed a double-blind study comparing the effectiveness of three days versus ten days of nitrofurantoin macrocrystal therapy. Localization of the infection to the lower urinary tract was presumed on the basis of clinical presentation. All patients had sterile urine on day two or three of therapy. In the ten-day group, two of 23 patients (8.7%) experienced a single relapse, and seven patients (30%) had 12 episodes of reinfection during a six-month follow-up. In the three-day group, two of 26 patients (7.7%) had a single relapse, and six patients (23%) had 12 episodes of reinfection. The rates of relapse and reinfection in the compared groups were not statistically significantly different (P greater than 0.05). Three days of treatment with nitrofurantoin macrocrystals is an effective regimen for symptomatic girls presumed to have uncomplicated lower urinary tract infections.

Alternatives to total splenectomy: two case reports.

Postsplenectomy sepsis is a serious problem with high morbidity and high mortality. Surgical alternatives to total splenectomy are being sought. This paper describes two cases where, after splenectomy, some splenic tissue was either reimplanted or was left in situ and remains functional.

Congential dyserythropoietic anemia--type IV.

Congenital dyserythropoietic anemia is characterized by ineffective erythropoiesis and increased numbers of multinucleated red cell precursors in the marrow. This syndrome has been subclassified on the basis of morphologic differences in the red cell precursors. Type I is characterized by megaloblastoid erythropoiesis and macrocytosis; Type II, by normoblastic multinuclearity and normocytosis; and Type III, by frequent giant multinucleated erythroblasts and macrocytes. Type II is further distinguished from the other types by serologic and ultrastructural abnormalities. The patient presented in this report does not fit any of the above categories; her red cells are similar to Type II congenital dyserythropoietic anemia cells, but no characteristic ultrastructural or serologic abnormalities are present. It is suggested that this patient may represent an additional variant of congenital dyserythropoietic anemia, Type IV.
