Cisplatin-5-fluorouracil chemotherapy for advanced inoperable squamous carcinoma of the head and neck

Patients with locally advanced, inoperable squamous cell carcinoma of the head and neck were offered three courses of cisplatin and 96-h 5-fluorouracil (5-FU) infusion. Subsequent therapy included surgery when feasible, irradiation therapy, and a maintenance program of methotrexate (MTX)-5-FU. Thirty-three patients were evaluated prospectively. Seven patients underwent a single course of chemotherapy. Five patients underwent two courses of chemotherapy. Twenty-one patients underwent three courses of adjuvant chemotherapy. The overall response rate was 48% (16 of 33). Fifteen of 21 patients (76%) receiving three courses of chemotherapy evidenced a response; this included three complete responses (CRs) (9%). No responses were seen in patients receiving only one or two courses of chemotherapy. Among responding patients, the initial favorable response to chemotherapy was apparent after the first course of chemotherapy. Patients who failed to demonstrate any response after two courses of chemotherapy did not respond after a third course. A significant group of patients fail to respond and should be offered participation in other investigational protocols as they become available.     

Retinopathy of prematurity: approaches to surgical therapy

Retinopathy of prematurity (ROP) is a vaso-proliferative disease with infiltration of the vitreous gel. Contraction of the infiltrate results in traction detachment with typical peripheral trough formation. Cryotherapy inhibits proliferation in the active stages of the disease (Stage 3, 'plus'). With development of traction detachment involving the macula (Stage 48) encircling buckling procedures should first be tried. Closed vitrectomy is considered when high retinal detachment and opacification by vitreous strands occur. The surgical technique is described. Anatomical (64%) and functional (43%) successes are reasonably high for Stage 4 cases, but disappointing (anatomical 40%, functional 16%) for Stage 5 ROP. Open funnels of detached retina fare better than closed ones. It is probably best to perform surgery not before the cicatricial stage, i.e. six months after birth.     

Risk Factors for a First Febrile Seizure: A Matched Case-Control Study

Summary We conducted a matched casecontrol study to identify risk factors for first febrile seizures, with special emphasis on characteristics of the acute illness episode. Cases were identified through hospital emergency departments; controls were identified through outpatient clinics and emergency departments. Sixtynine children with first febrile seizures and no history of previous unprovoked seizures were matched for age (±6 months), site of routine pediatric care, and date of visit (±weeks) with 1 or 2 febrile controls who had no history of previous febrile or unprovoked seizures. Medical records for the index visit were reviewed, and parents were interviewed by telephone. Illness characteristics examined included height of temperature, type of underlying illness, contact with a physician during the illness but before the index visit, and use of acetaminophen or decongestants. Family history of febrile and of unprovoked seizures, sociodemographic characteristics, daycare use, and selected preand perinatal variables were also studied. On multivariable analysis, significant independent risk factors were height of temperature, history of febrile seizures in a firstor in a higher degree relative. Gastroenteritis as the underlying illness had a significant inverse (i.e., protective) association with febrile seizures. Maternal smoking during pregnancy was a marginally significant predictor of febrile seizures.     

The effect of teacher reaction on student's interactive journal entries

The present study provides an analysis of the effects of particular patterns of teacher respose to students' entries in dialogue journals. It extended on previous research related to teacher-student instructional discourse by concentrating on written, teacher-student interactions. Second grade children who were participating in a daily dialogue journal activity were randomly subjected to two types of response patterns by their teacher. The results show that a teacher's elaborative responses to student journal entries directly lead to increase written output by students coupled with a distinct process #ophigher order#cp orientation of student entries.
