Background: The diagnostic and therapeutic approach to hilar cholangiocarcinoma and thus the prognosis have changed significantly over the last two decades. Nonetheless, hilar  cholangiocarcinoma  presents a complex surgical challenge.

Objectives: To assess the outcome of the radical approach for the management of types III and IV hilar  cholangiocarcinoma.

Methods: We conducted a retrospective single-center study. Preoperative diagnosis was based on ultrasound, computed tomography and selective percutaneous cholangiography without tissue diagnosis. Surgery was radical and included en-bloc liver, extrahepatic biliary tree and hilar lymph nodes resection, followed by biliary reconstruction with hepatico-jejunostomy.

Results: Fifteen patients (mean age 49 years, range 24–72) were managed accordingly. Anatomic classification of the biliary involvement was Bismuth-Corlette type IIIA (n=4), type IIIB (n=3) and type IV (n=8). The surgical procedures performed included four right hepatic lobectomies, five left hepatic lobectomies and six trisegmentectomies (all extended to the caudate lobe). Complete negative resection margins (R0) were accomplished in 12 cases (80%). Regional lymph node metastases were detected in five cases. There were two perioperative mortalities. Long-term follow-up (mean 30 months, range 6–72) revealed local recurrences in two cases, distant metastases in three, and both local and distant in two cases. Eleven patients are alive and 6 are without evidence of disease. The overall 2- and 5-year survival is 78% and 38% respectively.

Conclusions: In selected patients, the aggressive surgical approach to hilar cholangiocarcinoma is justified and can result in long-term survival.
 

Background: Infertility is one of the most prevalent health disorders in young adults.

Objectives: To study the distribution of causes of infertility in couples referred to primary infertility clinics in Israel.

Methods: Data for a 9 year period were derived from two clinics of major women's hospitals run by the country's largest health insurance funds. All patients were treated by one physician. Laparoscopy was not performed to rule out endometriosis.

Results: Of the 2515 couples identified, 1991 (79.2%) had a definitive diagnosis following complete workup (including hysterosalpingography). Mean age was 29.6 ± 6.0 years; mean duration of infertility was 1.7 ± 1.8 years. Primary infertility accounted for 65% of cases. Causes of infertility were male factor (45%), oligo-ovulation disorders (37%), and tubal damage (18%). Infertility factors were identified in the woman alone in 30.6% of cases and the man alone in 29.2%. Two combined infertility factors were found in 18% of patients, and three combined factors in 0.5%. The rate of unexplained infertility (which probably includes non-tubal endometriosis) was 20.7%.

Conclusions: As male factor accounts for almost half of all cases of infertility in couples, sperm analysis is mandatory before any treatment.
 

Background: Overlap syndrome is an entity that satisfies the criteria of at least two connective tissue diseases. These conditions include systemic sclerosis, dermatomyositis or polymyositis, Sjogren's syndrome, rheumatoid arthritis and systemic lupus erythematosus. A combined pathology has impact on the clinical features, diagnosis and treatment.

Objectives: To analyze the features of SSc[1] patients with overlap syndrome registered in the European (EUSTAR) database at our center and to review the literature focusing on clinical and diagnostic issues and new treatments.

Methods: We studied the medical records of 165 consecutive SSc patients and reviewed cases with scleroderma overlap syndrome. Using the key words “overlap syndrome," "systemic sclerosis," “connective tissue disease” and “biological agents” we conducted a PubMed search for the period 1977 to 2009.

Results: Forty patients satisfied the criteria for scleroderma overlap syndrome. The incidence of additional connective tissue diseases in the whole group and in the overlap syndrome group respectively was: dermatomyositis or polymyositis 11.5% and 47.5%, Sjogren's syndrome 10.3% and 42.5%, rheumatoid arthritis 3.6% and 15.4%, and systemic lupus erythematosus 1.2% and 5.0%. Coexistence of SSc and another CTD[2] aggravated the clinical course, especially lung, kidney, digestive, vascular and articular involvement. Non-rheumatic complications mimicked SSc complications. An additional rheumatic or non-rheumatic disease affected treatment choice.

Conclusions: The definition of scleroderma overlap syndrome is important, especially in patients who need high-dose corticosteroids for complications of a CTD. The use of novel biological therapies may be advocated in these patients to avoid the hazardous influences of high-dose steroids, especially renal crisis. In some overlap syndrome cases, biological agents serve both conditions; in others one of the conditions may limit their use. In the absence of formal clinical trials in these patients a cautious approach is preferred.

Objectives: To assess our experience with perichondritis in a large group of patients hospitalized with this entity.

Methods: We retrospectively studied 114 patients who were admitted with perichondritis during 1987–2004, including their demographic details, medical history, current illness, etiology, pathogens and treatments. 

Results: The patients’ mean age was 41.8 ± 20.7 years. In more than half of the patients the etiology could not be determined. Forty-seven patients (41%) were treated prior to hospitalization for an average of 2.5 ± 1.9 days. Eight patients (7%) required surgical intervention. Pseudomonas aeruginosa was found to be the predominant organism (69% of available isolates) and was associated with a more advanced clinical presentation and longer hospitalization (P = 0.008). 

Conclusions:  Perichondritis develops in many cases after apparent minor trauma. Since P. aeruginosa is probably the predominant pathogen, initial treatment should include anti-pseudomonal antibiotics.

Background: The rate of brain abnormalities in asymptomatic term neonates varies substantially in previous studies. Some of these rates may justify general screening of healthy newborns by head ultrasound.

Objectives: To assess the incidence of intracranial abnormalities among asymptomatic term newborns with HUS[1] and to detect high-risk populations that might need such screening.

Methods: This was a prospective study in 493 term newborns who underwent HUS and a neurological evaluation during the first 3 days of life. The neurological examination results were unknown to the sonographist and the examiner was blinded to the HUS findings. The abnormal HUS findings were classified as significant or non-significant according to the current literature.

Results: Abnormal HUS was found in 11.2% of the neonates. Significant findings were noted in 3.8% of the infants. There was no association between non-structural HUS findings (hemorrhage or echogenicity) and mode of delivery. There was no relationship between any HUS abnormality and birth weight, head circumference and maternal age, ethnicity, education or morbidity. The rate of abnormal neurological, hearing or vision evaluation in infants with a significant abnormal HUS (5.2%) was comparable to the rate in infants with normal or non-significant findings on HUS (3.1%).

Conclusions: There is no indication for routine HUS screening in apparently healthy term neonates due to the relatively low incidence of significant brain abnormalities in these infants in our population.
