Background: The need for postnatal monitoring of infants exposed to intrauterine beta blockers (BBs) has not been clearly defined.

Objectives: To evaluate infants exposed to intrauterine BBs in order to estimate the need for postnatal monitoring.

Methods: This retrospective case-control study comprised 153 term infants born to mothers who had been treated with BBs during pregnancy. Treatment indications included hypertension 76 mothers (49.7%), cardiac arrhythmias 48 (31.4%), rheumatic heart disease 14 (9.1%), cardiomyopathy 11 (7.2%) and migraine 4 (2.6%). The controls were infants of mothers with hypertension not exposed to BBs who were born at the same gestational age and born closest (before or after) to the matched infant in the study group.

Results: Compared to the control group, the infants in the study group had a higher prevalence of early asymptomatic hypoglycemia (study 30.7% vs. control 18.3%, P = 0.016), short symptomatic bradycardia events, other cardiac manifestations (P = 0.016), and longer hospitalization (P < 0.001). No life-threatening medical conditions were documented. The birth weight was significantly lower for the high-dose subgroup compared to the low-dose subgroup (P = 0.03), and the high-dose subgroup had a higher incidence of small-for-gestational-age (P = 0.02).

Conclusions: No alarming or life-threatening medical conditions were observed among term infants born to BB treated mothers. These infants can be safely observed for 48 hours after birth close to their mothers in the maternity ward. Glucose follow-up is needed, especially in the first hours of life.

Background: The estimated incidence of esophageal atresia (EA) with or without tracheo-esophageal fistula (TEF) is 1:3500 live births. During childhood these patients have various co-morbidities, but the overall quality of life among adults is similar to that of the general population.

Objectives: To evaluate short- and long-term co-morbidities and quality of life among infants born with EA ± TEF at a large single medical center.

Methods: Medical records of 65 children born over a 21 year period were reviewed for short- and long-term medical data. Telephone interviews were conducted with 46 of their parents regarding medical problems and quality of life after home discharge.

Results: The main long-term co-morbidities during the first 2 years of life, 4–6 years of age, and during adolescence (12–16 years) included gastro-esophageal reflux disease (GERD) in 56.5%, 35.8%, and 18.7%, respectively; stridor in 84.8%, 45.2%, and 12.5%, respectively; hyper-reactive airway disease (HRAD) in 43.5%, 35.5%, and 36.5%, respectively; recurrent pneumonia in 43.5%, 32.3%, and 18.8%, respectively; and overall recurrent hospitalizations in 87%, 41.9%, and 25%, respectively. The quality of life was reportedly affected among 100%, 75%, and 33.3% respectively.

Conclusions: Long-term follow-up of patients with EA ± TEF indicates a high burden of co-morbidities during the first 6 years of life, with a gradual decrease in symptoms thereafter. Nevertheless, HRAD continued to impact the daily life of about one-third of the older adolescents, and GERD one-fifth. A long-term multidisciplinary follow-up should be conducted to prevent late onset complications that may affect the quality of life.

Background: Thyroid-associated ophthalmopathy (TAO) is an inflammatory disease that affects the thyroid gland and the eye orbit. Of patients with TAO, 3%–5% have severe sight-threatening disease due to optic neuropathy Optical coherence tomography (OCT), the non-invasive imaging technology that yields high-resolution cross-sectional images of the retina, provides qualitative and quantitative data on the retina.

Objectives: To apply this technique to quantitatively assess retinal nerve fiber layer (RNFL) and macular ring thicknesses in healthy subjects and in patients with TAO to determine their relationship to the severity of the orbital disease.

Methods: All patients in the ophthalmology clinic who were diagnosed with TAO and underwent OCT imaging as part of their ocular examination comprised the study group, and healthy patients who volunteered to undergo OCT examination served as controls. Results of the complete ophthalmologic examination and OCT findings were collected from medical files, including the thickness of the RNFL and the macula.

Results: The study comprised 21 patients and 41 healthy controls. TAO patients exhibited RNFL thickening and inner macula thinning compared to healthy subjects. Mean RNFL thickness was correlated with the severity of the orbital disease.

Conclusion: The OCT findings suggest that the retina is involved in TAO, probably as early as the subclinical stage. This highlights the ability of OCT to identify retinal changes earlier and far more accurately than is detected today, enabling earlier diagnosis and more timely treatment to prevent severe visual sequelae.

Background: Multiple primary malignancies are increasingly being detected among cancer patients. Objectives: To investigate the co-occurrence of primary bladder cancer and primary lung cancer, two established smoking-related neoplasms characteristically associated with increased risk of secondary cancers.

Methods: A retrospective search of the patient registry in our institution identified 25 patients (23 men and two women) who were diagnosed with both bladder cancer and lung cancer during the period 1990–2005. Medical records were reviewed and clinical and pathological data were extracted.

Results: In 21 patients (84%) bladder cancer was the first primary tumor and in 4 (16%) the second primary tumor. More than 90% of the patients had a history of smoking. Mean smoking exposure was 62.1 pack years (range 30–120). All bladder cancers were transitional cell carcinomas with the majority being superficial at presentation. Most lung cancers were of the non-small cell type. Second primary lung cancers were significantly more advanced at diagnosis. Overall, mean follow-up was 105.8 months (range 6–288). Seven patients (28%) were alive at the time of evaluation; 68% died of lung cancer, while none died of bladder cancer.

Conclusions: Second primary lung cancer may occur in patients with bladder carcinoma and vice versa. In view of the relatively frequent involvement of the genitourinary tract as a site of multiple primary tumors, urologists may have a key role in the detection of second primary tumors arising in the genitourinary tract, or second primary tumors that occur in patients with primary genitourinary tract malignancies.
 

Background: Extensive necrosis is rare in primary renal cell carcinoma. This finding may reflect the biological characteristics of the carcinoma and therefore could be of prognostic and clinical value.

Objectives: To assess the incidence of necrosis in renal cell carcinoma and its potential prognostic value.

Methods: We conducted a consecutive retrospective study of 173 patients after radical nephrectomy for renal cell carcinoma. Clinical and pathological data were collected from hospital medical records and compiled into a computerized database.

Results: Extensive necrosis was found in 31 tumor specimens (17.9%). Univariate analysis showed that the specimens with extensive necrosis were significantly larger and manifested more perirenal and venous extension than the tumors without necrosis. The size of the renal tumor was the only parameter that remained significant in multivariate analysis (P=0.0001). Overall disease-free survival did not differ significantly between patients with necrotic tumors and those without (68% and 66% respectively).

Conclusions: The finding of extensive necrosis in renal cell carcinoma specimens does not seem to be related to tumor biology but rather may reflect the relation between size and vascularity of the tumor.
