Follicle size by ultrasound versus cervical mucus quality: normal and abnormal patterns in spontaneous cycles

Ultrasound (US) has been demonstrated to be the method of choice for diagnosing luteinized unruptured follicle syndrome and to be a valuable adjuvant in the assessment of luteal phase defect. In this prospective study, the use of US with postcoital testing (PCT) is evaluated. Fifty control infertility patients were examined with serial US for follicle dynamics in conjunction with PCT. Standard curves for follicle dynamics versus cervical mucus quality (Insler score) were calculated. Eighteen patients referred for abnormal mucus underwent similar evaluation. Their follicle dynamics versus mucus quality were compared with those of the controls. The findings were: (1) there is a predictable relationship between follicle size and mucus quality, (2) the majority of patients with abnormal mucus have normal follicular dynamics, and (3) a minority of patients with abnormal mucus have either a narrow mucus window or abnormal follicular dynamics. In addition, US was found to be cost-effective in the overall fertility evaluation.     

Mucociliary activity of free transplanted respiratory epithelium]

The function of free grafted respiratory epithelium was investigated in inbred rats. In nine of ten animals it could be shown that the respiratory epithelium not only regenerated as an epithelial surface lining but also regained mucociliary activity. The grafted epithelium was able to secrete mucus, which was equal in protein fragmentation to the secretion of normal nasal mucosa. The grafted respiratory epithelium showed normal ciliary function which could be demonstrated by recording the ciliary beat pattern present and by subsequent histological examination. Morphologically, a regular structure of ciliae (9 + 2) was found on the upper pole of the regenerated ciliated cells.     

UPPP for habitual snoring: A 5-year follow-up with respiratory sleep recordings

Fifty-six men who underwent uvulopalatopha-ryngoplasty (UPPP) because of habitual snoring without preoperative obstructive sleep apnea (OSA), according to respiratory sleep recordings, were interviewed concerning persistent snoring and excessive daytime sleepiness (EDS). Renewed recordings were made in 53 of them at a median time of 63 months postoperatively. Median preoperative oxygen desaturation index (ODI) was 0; the median postoperative index was 1. Median duration of the preoperative obstructive respiratory pattern was 8% of total sleeping time, and the median duration postoperatively was 17%. (Significant individual increases were P=.0005 and P=.004, respectively.) Six patients answered to OSA criteria postoperatively. Weight increases were significantly correlated to increases in both ODI and obstructive respiratory pattern and to persistent snoring. Preoperatively 51 of 56 patients reported EDS, and 73% of the patients were improved or cured. From snoring, 87% reported improvement or cure. No patient had any serious sequelae of UPPP. Uvulopalatopharyngoplasty is a safe and effective treatment for habitual snoring, but it does not give absolute protection from development of OSA.     

Intellectual development in school-aged children with asymptomatic congenital cytomegalovirus infection

Congenital cytomegalovirus infection occurs in about 1% of live births. Although symptomatic congenital infection often results in severe developmental deficits and mental retardation, about 90% have asymptomatic infection. Previous studies of the intellectual development in children with asymptomatic congenital cytomegalovirus have resulted in mixed findings. To control for the effects of hearing impairment (which occurs in about 15% of asymptomatic children) on intelligence scores, we tested 18 prospectively followed, normally hearing, school-aged children with asymptomatic congenital cytomegalovirus (15 black, ten male) and 18 controls matched for age, sex, race, school grade, and socioeconomic status. Children were tested via the Wechsler Intelligence Scale for Children-Revised, the Kaufman Assessment Battery for Children, and the Wide Range Achievement Test. Multivariate analysis revealed no differences between groups on intelligence scores or subscales, achievement scores, or incidence of learning disabilities (defined as significant discrepancy between intelligence and achievement), and mean scores for both groups were very close to national norms. It is concluded that the 25,000 children born in the United States each year with asymptomatic congenital cytomegalovirus and normal hearing are not likely to be at increased risk of mental impairment.     

Melanoma of the larynx

Primary laryngeal melanomas (LM) are rare. In a review of all mucosal melanomas of the head and neck (MMHN) at Memorial Hospital from 1949 to 1983 we identified only three such cases. Review of the literature shows that LM usually involve the supraglottic larynx of elderly males. Although survival is as poor as for other MMHN, local recurrence is less frequent, even when primary therapy consists of more conservative surgical procedures than total laryngectomy.     

Effect of Surgery on the Outcome of Midgut Carcinoid Disease with Lymph Node and Liver Metastases

We have evaluated survival and tumor-related symptoms in the presence of mesenteric lymph node and liver metastases in relation to surgical procedures in 314 patients (148 women, mean age at diagnosis 61 years; 249 with liver metastases) treated for midgut carcinoid tumors. Of the operated patients, 46% presented with severe abdominal pain and intestinal obstruction and were operated on before the diagnosis. Medical treatment (somatostatin analogs, interferon-a) was initiated in 67% and 86%, respectively. Surgical attempts included small intestine or ileocecal/right-sided colon resection with excision of mesenteric lymph node metastases. Most of the patients (n = 286) had mesenteric lymph node metastases; 33% of them had unresectable mesenteric lymph node metastases and underwent surgery without mesenteric dissection. Patients who underwent resection for the primary tumor had a longer survival than those with no resection (median survival 7.4 vs. 4.0 years; p <0.01). Patients who underwent successful excision of mesenteric metastases had a significantly longer survival than those with remaining lymph node metastases. Patients operated on for a primary tumor but with remaining lymph nodes but no liver metastases and who subsequently received interferon and somatostatin analog treatment had a median survival of 7.4 years. Resection of the primary tumor and the mesenteric lymph node metastases led to a significant reduction in tumor-related symptoms. Surgery to remove the primary intestinal tumor including mesenteric lymph node metastases is supported by the present results, even in the presence of liver metastases. Liver metastases and significant preoperative weight loss are identified as major negative prognostic factors for survival.
