A randomized controlled trial of a new fetal acoustic stimulation test for fetal well-being

OBJECTIVES: Our purpose was to determine (1) whether a fetal acoustic stimulation test results in more palpable fetal movement compared with a mock test (control) and (2) whether palpated fetal movements after a fetal acoustic stimulation test are accompanied by a reactive nonstress test.STUDY DESIGN: In a randomized controlled trial we studied women seen in the labor and delivery suite for various indications. Women were excluded for multiple gestation, <31 weeks' gestational age, treatment with magnesium sulfate or narcotics, or ruptured membranes. Informed consent was obtained from eligible women, who were then randomized to a test or control group. We placed an acoustic stimulator on the abdomen of each woman, but only the test group was stimulated. We assessed fetal movement by a grading system: 0 = no fetal movement felt by patient or tester, 1 = fetal movement felt by patient only, 2 = fetal movement felt by tester, 3 = visual movement seen by tester. A positive fetal acoustic stimulation test result was defined as one with any fetal movement felt or seen by the tester (grades 2 or 3). We then performed a nonstress test. We compared rates of a positive fetal acoustic stimulation test in the test and control groups with the χ² test. A p value <0.05 was considered significant.RESULTS: We randomized 297 women to the test group and 280 women to the control (mock test) group. Of women tested with the fetal acoustic stimulation test, 81% had fetal movement by palpation or visualization (grades 2 or 3) compared with 19% of the control group (p < 0.0001, odds ratio 19.29, 95% confidence interval 12.42 to 30.07). Of the test group, 283 (95%) had a reactive nonstress test and 14 (5%) had nonreactive tests; the control group had 267 (95%) reactive and 13 (5%) nonreactive nonstress tests. Of 242 patients in the test group with a positive fetal acoustic stimulation test, 236 (98%) had a reactive nonstress test. Of those in the test group with fewer than three contractions per 10 minutes, 164 (89%) had a positive fetal acoustic stimulation test. Of these, 162 (99%) had a reactive nonstress test.CONCLUSION: The fetal acoustic stimulation test evokes significantly more palpated or visualized fetal movement than in controls. Palpated or visualized fetal movement after acoustic stimulation was almost always accompanied by a reactive nonstress test. (Am J Obstet Gynecol 1997;176:1386-8.)     

The Micropouch Gastric Bypass: Technical Considerations in Primary and Revisionary Operations

Background: Roux-en-Y gastric bypass is an effective procedure for the long-term control of morbid obesity. An eventual revisionary operation, however, is necessary for some patients (0.8-29%). Redo procedures are required for pouch enlargement, stapleline dehiscence, or marginal ulceration. In 1994, the micropouch gastric bypass (MBG) was developed to eliminate the need for a repeat operation. Its design was based on two anatomical principles: 1) The fundus is elastic, aperistaltic, and may significantly dilate over time; 2) The proximal magenstrasse contains a high concentration of parietal cells, which potentiates the risk for marginal ulceration or gastroesophageal reflux after vertical pouch restriction. Construction of a micropouch limited to the gastric cardia avoids using the fundus and proximal lesser curvature, but requires a greater mobilization of the stomach and its peritoneal attachments. Methods: Between February 1994 and February 2000, 1,120 patients underwent the MGB as a primary or revisionary operation.The fundus was mobilized completely, including transection of the left phreno-esophageal and gastrophrenic ligaments. The transected pouch was limited to the gastric cardia with 1 cm of fundus incorporated into the gastrojejunostomy stoma (GJS). Results: There were 10 anastomotic leaks at the GJS (0.9%). All leaks sealed following surgical drainage or parenteral nutrition. One patient required re-operation (0.09%) for a dilated pouch and marginal ulceration. An additional patient (0.09%) developed a gastrogastric fistula secondary to a pharmacobezoar and stomal stenosis. Conclusion: With an appreciation for the finer anatomy of the proximal stomach and intra-abdominal esophagus, the micropouch can be constructed safely in both primary and redo procedures. The MGB, now in its seventh year, is durable and has, with rare exception, eliminated pouch enlargement, staple-line separation, reflux esophagitis, and marginal ulceration.     

Laser Hair Removal with Alexandrite versus Diode Laser Using Four Treatment Sessions: 1-Year Results

BACKGROUND: Laser hair removal is the treatment of choice for hypertrichosis. The two most commonly used hair removal lasers are compared. OBJECTIVE: To present the results of a comparative study examining the role of wavelength, fluence, spot size, pulse width, and cooling systems on long-term results after a series of four laser hair removal treatments using the 755 nm alexandrite and 800-810 nm diode lasers. METHODS: The axillae of 15 untanned, type I-V patients were treated side by side four times at 4- to 6-week intervals with a 755 nm, 3-msec pulse width, cryogen spray-equipped alexandrite laser and an 800 nm, variable pulse width, cooled sapphire window-equipped diode laser. Each patient was pretested and treated with the maximum fluence tolerated at the largest spot size available for each laser (12 mm round/113 mm2 for the alexandrite and 9 mm for the diode). RESULTS: Evaluations were done at 3, 6, 9, and 12 months after the last treatment. Twelve-month results with the alexandrite and diode lasers achieved 85% versus 84% hair reduction. The fact that tan avoidance was strictly followed permitted the use of relatively high fluences (25-30+ J/cm(2)) even in type IV patients. For most patients, four treatment sessions using high fluences (30-40 J/cm(2)) with relatively large spot sizes (12 mm round for the 755 nm alexandrite and 9 mm for the 800 nm diode) resulted in 12-month hair reductions in the 90% range. CONCLUSION: Both the alexandrite and diode lasers in this 12-month study produced excellent long-term hair reductions.     

Primary and preventive care in a university obstetrics and gynecology group practice

Objective: Our purpose was to determine whether primary and preventive care is practiced by a university obstetrician-gynecologist group practice.Study design: A retrospective chart review spanning 2 years of four academic physicians' private practices was performed. A total of 335 patients were reviewed with 739 patient encounters and 1032 patient problems identified. The definition of a primary care physician according to The American College of Obstetricians and Gynecologists was used to standardize data collection and evaluation.Results: Obstetric complaints accounted for 27.7% of all visits, whereas 65.4% were for gynecologic problems. Almost 7% of all complaints were neither obstetric nor gynecologic, and of those 74.6% were primary care problems completely managed by the obstetrician-gynecologist. Only 19.7% of these were referred for management. More than 89% of all encounters () involved some element of primary care.Conclusion: This study provides evidence that the majority of health care provided by the obstetrician-gynecologists is primary care.     

Multiple myeloma in an adolescent

The radiographic findings of a 15-year-old Brazilian male with diagnosis of multiple myeloma are described. He presented with claudication and recent onset of tender painful swelling of the right mid leg. Radiographs showed wide spread soap bubble lesions of the skull, long bones, spine, pelvis, ribs, shoulders, and clavicles. The diagnosis was confirmed by the presence of a plasmacytoma on tissue biopsy (femur), serum IgG gammopathy and Bence-Jones proteinuria.Supported by grants (CA-20180 and CA-21765) from the National Cancer Institute and the American Lebanese Syrian Associated Charities (ALSAC)     

Shin splints Painful to have and to treat

When people overuse their legs they develop an uncomfortable awareness of these limbs manifested as a dull burning or aching. The cause is often clear to the person with the problem as a result of the often obvious relationship to overdoing an exercise or activity and the pain. “Shin splints” is the lay term; physicians use the term medial tibial stress syndrome. The pathophysiology that leads to this pain is unclear, although there are a number of competing theories. Differential diagnosis includes stress fractures and compartment syndromes. Bone tumors or lipomas can also cause similar pain to shin splints. Diagnosis can be made by history alone in a majority of cases, but if the diagnosis is unclear, an X-ray and magnetic resonance imaging should be considered. Treatment is still mostly supportive and symptom related. Rest is the most important aspect of treatment. Locally applied cold and anti-inflammatory medication have also been felt to be beneficial.

When to start antiretroviral therapy

The current literature is controversial in providing evidence to determine the optimal time to initiate therapy among patients with HIV. However, there is evidence that initiating early treatment might provide benefits by treating primary HIV infection, preserving normal immune function, suppressing HIV viral replication, deferring clinical progression, and reducing HIV transmission. The biggest challenges in initiating treatment early are issues related with long-term management, including toxicities, adherence, and drug resistance. However, the availability of superior new antiretroviral drugs and simplified regimens, the development of effective treatment strategy, and further improvement of adherence through directly observed treatment are addressing the issues and changing the balance towards earlier treatment.
