Heat-conduction error of temperature sensors in a fluid flow with nonuniform and unsteady temperature distribution.

In temperature measurement of non-isothermal fluid flows by a contact-type temperature sensor, heat conduction along the sensor body can cause significant measurement error which is called "heat-conduction error." The conventional formula for estimating the heat-conduction error was derived under the condition that the fluid temperature to be measured is uniform. Thus, if we apply the conventional formula to a thermal field with temperature gradient, the heat-conduction error will be underestimated.

Gaze direction modulates the disengagement of attention from facial expression in 10-month-olds.

This study investigated whether the disengagement of attention from facial expression is modulated by gaze direction in infants. To this end, we measured the saccadic reaction time required for the 10-month-olds to disengage their attention from angry and happy expressions combined with either straight or averted gaze. The 10-month-olds' disengagement of their attention from happy faces was modulated by gaze direction.

Seroepidemiological survey of cytomegalovirus infection among pregnant women in Nagasaki, Japan.

Background: Epidemiology of cytomegalovirus (CMV) infection varies widely, depending on ethnicity and socioeconomic status. A seroepidemiological survey was conducted to determine CMV infection among pregnant women in Nagasaki Prefecture, Japan.

Methods: We measured serum CMV-specific immunoglobulin (Ig) M and IgG at the first and third trimesters.

Retrospective diagnosis of congenital cytomegalovirus infection at a school for the deaf by using preserved dried umbilical cord.

A retrospective diagnosis of congenital cytomegalovirus infection was made for 3 of 26 students (12%) with either bilateral profound or severe sensorineural hearing loss at a School for the Deaf in Japan by detecting viral DNA with real-time polymerase chain reaction from dried umbilical cords that had been preserved at home.

The calming effect of a maternal breast milk odor on the human newborn infant.

We examined the effects of the odors from mother's milk, other mother's milk and formula milk on pain responses in newborns undergoing routine heelsticks. Forty-eight healthy infants were assigned to four groups, an own mother's breast milk odor group (Own MM), another mother's breast milk odor group (Other MM), a formula milk odor group (Formula M) and a control group. To assess infant distress in response to the heelsticks, their crying, grimacing and motor activities were recorded during the experiment as behavioral indices of the pain response.

Giant cystic meconium peritonitis associated with a cloacal anomaly: case report.

This report describes a case of giant cystic meconium peritonitis (GCMP) associated with a cloacal anomaly. Antenatal ultrasonography and magnetic resonance imaging demonstrated persistent fetal ascites, bilateral hydronephrosis, and 3 pelvic cystic structures. The baby girl showed duplicated hydrocolpos and a single orifice of the cloaca with a long common channel inducing a urinary outflow obstruction.

[Genetically confirmed nosocomial transmission of staphylococcal scalded skin syndrome between two infants in the neonatal intensive care unit].

We report two consecutive cases of staphylococcal scalded skin syndrome (SSSS) in our neonatal intensive care unit (NICU). Methicillin-resistant Staphylococcus aureus (MRSA) was isolated from skin swabs. An epidemiological survey conducted on the NICU staff, isolated MRSA from nasal swabs of three personnel.

Severe postnatal cytomegalovirus infection in a very premature infant.

Several studies have reported that postnatally acquired cytomegalovirus (CMV) infection can cause sepsis-like syndrome in premature infants. We here report a 622-gram birth weight male infant of 23 weeks' gestation who had sepsis-like syndrome and pneumonia. Substantial CMV loads were detected in peripheral blood cells, plasma, and urine when the patient was in crisis, but was decreased in parallel to clinical improvement without using ganciclovir.

Clinical outcome of infants with confined placental mosaicism and intrauterine growth restriction of unknown cause.

The purpose of this study was to know a role of confined placental mosaicism (CPM) in perinatal outcome and postnatal growth and development of infants with intrauterine growth restriction (IUGR). We selected 50 infants with IUGR (<-2.0 SD) from 3,257 deliveries in a regional medical center during the past 10-year period, and carried out cytogenetic and molecular analyses in their placenta and cord blood.

[Anesthetic management of a neonate with laryngotracheoesophageal cleft and tracheoesophageal fistula].

Laryngotracheoesophageal cleft (LTEC) is an extremely rare congenital anomaly characterized by an absence of all or a part of the tracheoesophageal septum producing an abnormal communication between the trachea and esophagus, and is often difficult to be diagnosed. A 2-day-old male baby was tentatively diagnosed as tracheoesophageal fistula type Gross C, and underwent gastrostomy. The trachea was intubated before anesthetic induction.
