יותר ויותר מתבהר הצורך לאבחן ולטפל בחוסר הביוץ. אי-הפוריות היא רק תוצאה אחת, קביעת האבחנה וטיפול בתאם יכולים למנוע תופעות שליליות נוספות לבריאות האשה. תוצאות של חוסר ביוץ כוללות ירידה בצפיפות העצם, ירידה בחימוד (ליבידו), תופעות בלתי רצויות בעור ובשיער, שיגשוג בלתי מבוקר של רירית הרחם (endometrium), מצב קרדיוואסקולרי מעורער ושינויים פסיכולוגיים ופסיכיאטריים. התוצאות הסוציאליות והפסיכוסוציאליות של חוסר הביוץ לא תמיד בתודעתנו, למרות חשיבותן הרבה. על כן, כדי לייעץ נכון למטופלת, דרושה אבחנה מדויקת, ככל האפשר.

המושג הבסיסי להבנת הפתוגנזה של הפרעות ביוץ קשור בהבנת העובדה, שהפרשה פעימתית מתאימה של GnRH (Gonadotropin Releasing Hormone) מההיפותאלאמוס במוח קובעת את מועד הביוץ והווסת. פעימות של GnRH מהירות או איטיות מדי יגרמו לחוסר ביוץ או להרס הגופיף הצהוב השחלתי טרם זמנו...
 

Retinal Injury Induced by Laser Pointers

Laser pointers originally designed for use during presentations are ubiquitous and are even sold as toys (such as pens or on key chains) in drug stores. Though reported as safe, the laser pointers still carry the risk of potential damage to the eye. We report a 16-year-old boy with bilateral retinal injury caused by 20-30 seconds of exposure to a laser pointing-device. Immediately thereafter, vision was blurred bilaterally and he noted a central red scotoma in each eye. Symptoms resolved spontaneously within 2 days but the retinal scars remained all during the 10 months of follow-up.

It is clear from our report and 3 other publications that retinal damage can develop from misusing laser pointers. Laser hazards and safety should be stressed for the general public. We recommend that laser-pointers should not be available as toys to children and teenagers.

Prostatic cancer (PC) is second only to lung cancer as a cause of cancer mortality in men word-wide. In Israel it is the most common cause of cancer mortality in men, after lung cancer and colo-rectal cancer.

We screened, for the first time in Israel, for prostatic cancer using serum levels of PSA and a digital rectal examination (DRE). The purpose was not only to diagnose PC but also to increase public awareness of the condition.

300 men in the Haifa area who met statistical criteria for early diagnosis of PC participated. They filled a questionnaire regarding risk factors for PC (age, family history (FH) of prostatic and breast cancer, cigarette smoking, alcohol consumption, previous PSA sampling) and were examined. Those who had out-of-ragne, age-related PSA values, or a pathologic DRE underwent trans-rectal ultrasound (TRUS) examination and guided biopsy of the prostate. Those with a positive biopsy for PC underwent radical prostatectomy or radiation therapy.

41 (14.3%) had out-of-range, age-related PSA levels and 10 (3.5%) had a pathologic DRE. 39 (13.3%) underwent TRUS and biopsy and 6 (2.04%) had clinically significant PC, all early stages (Gleason 4-6).

Correlation between age and PSA has been proven statistically significant (p<0.05). Symptoms of urinary tract obstruction and nocturia were related to a high PSA (p=0.035 and 0.002, respectively). Those with PC had at least 1 symptom of urinary tract obstruction; 6 (15.3%) who underwent TRUS and biopsy and a FH of prostate cancer. However, no subject with a FH of PC had biopsy-proven cancer. Those with PC had PSA values from 4.9 to 31.8 ng/ml (9.6 median). Age-related PSA had a positive predictive value of 17.1%.

Results of our annual screening for early detection of PC using age-related PSA, and DRE are encouraging: cases detected were clinically significant and treatable. It would appear that screening for PC will result in decreasing the incidence of metastatic cancer and therefore mortality.

Circumcision, so commonly performed, is considered a safe procedure rarely associated with significant complications. A case of complete amputation of the glans penis during neonatal circumcision is reported. The glans was successfully reimplanted, with good post-operative functional and esthetic results.

Medical malpractice suits in obstetrics comprise about 10% of all claims against medical institutions in Israel. A significant proportion are due to failures relating to fetal monitoring. We studied the characteristics of 102 of 4125 obstetrical cases reported to the Medical Risk Management Co. as being at risk for a malpractice suit.

The cases were divided into those with medical management failures (misinterpretation of fetal monitor tracing, failure to respond promptly to fetal monitoring indicating distress, etc.) and technical failures (loss of monitor tracings, interruption in the tracing at a critical time, unreadable tracings, etc.).

The monetary quantum in fetal monitoring failures exceeded $30,000,000. The majority of these failures could have been avoided by using central electronic fetal monitoring systems with alerting and archival capabilities.

Thrombocytopenic purpura associated with brucellosis has rarely been described in children. The thrombocytopenic purpura is usually part of the array of manifestations of brucellosis, such as fever, malaise, arthralgia, arthritis, hepatosplenomegaly and lymphadenopathy.

We describe a 4-year-old girl in whom severe thrombocytopenic purpura was the only manifestation of brucellosis which resolved after appropriate antibiotic therapy. We conclude that brucellosis should be included in the differential diagnosis of thrombocytopenic purpura in areas endemic for brucellosis, and when there is a history of exposure to infected food products.

The use of albumin has been a matter of debate since its introduction in the 1940's. Albumin is not only expensive but may also be harmful when administered inappropriately. Until recently our use of albumin was controlled by a number of authorized physicians who signed all albumin prescriptions.

In August 1998, a multidisciplinary team reviewed the indications for albumin use and introduced simple guidelines for its supply and administration. As a result, the use of albumin has decreased by almost 70%. This indicates that rational use of albumin can be achieved by appropriate guidelines, without requiring administrative limitations. We believe that this conclusion holds true for other diagnostic and therapeutic procedures as well.

The femoral artery remains the most used peripheral site for radiological catheter access. With a greater number of both diagnostic and therapeutic procedures being performed by interventional radiologists and cardiologists, and with larger catheters being used for stenting and endovascular grafting, the incidence of iatrogenic pseudo-aneurysms reported has reached as high as 0.5-2%. Ideally, they should thrombose spontaneously. However, when this does not occur, management options include: observation, ultrasound-guided obliterative compression, direct thrombin injection, embolization, stent graft insertion, and very rarely- surgery.

During a 7-year period (1992-1999) we treated 131 cases of femoral artery false aneurysms. Until 1998 ultrasound-guided compression-obliteration, with a 95% success rate, was our method of choice. Since 1998, direct thrombin injection, with 100% success in 24 cases, has become our preferred method. It is pain-free, fully successful even in anticoagulated patients, and is currently our treatment of choice.

The use of testicular spermatozoa for intracytoplasmic sperm injection introduced a new treatment modality for management of male infertility.

Since testicular biopsies of non-obstructive azoospermic men are not homogenous in their histological patterns, identification with certainty of focal spermatogenesis might be difficult, particularly in those with small foci of spermatogenesis. We used an immunohistochemical marker of the male germ line, an antibody generated against RBM (RNA-binding-motif), to recognize with high precision the presence of germ cells in the biopsy. Biopsies of 30 men with azoospermia, most with non-obstructive azoospermia and a few with obstruction of the vas deferens, were evaluated.

Immunohistochemical staining for RBM protein contributed to the detection and accuracy of the identification of germ cells. Furthermore, this immunohistochemical technique aided the histopathologist to focus on even small foci of spermatogenesis. Absence of the protein expression confirmed the diagnosis of Sertoli-cell-only syndrome. The results indicate that expression of RBM can be a diagnostic marker for identifying the germ cells of small concentrations of spermatogenesis. This method can enhance the accuracy of histopathological evaluation of testicular biopsies that had formerly relied mainly on hematoxylin-and-eosin staining.

Liver transplantation is the treatment of choice for end- stage liver disease. During the past 8 years we performed 102 liver transplants in 84 adults and 16 children. In the adults, 9 were combined transplants: 1 a liver-pancreas transplant for type I diabetes, and 8 liver-kidney transplants. In the children, transplants included 5 whole-livers, 5 left-lateral liver segments from living-related donors, 4 reduced-grafts of right or left lobes, and 2 split left-lateral segments.

At a mean follow-up of 31 months (range 1-96) 70 were alive, 3 had died during surgery and 15 during the first postoperative months. Mortality was due to primary graft non-function (7), sepsis (10), intracranial hemorrhage (1), tumors (4), recurrent hepatitis B (2), biliary strictures (2) and chronic rejection (1). The 1- and 4-year survival rates were 79.5% and 69.6%, respectively.

After transplantation, 10 developed biliary stricture (5 corrected by balloon dilatation) and 8 anastomotic stricture (7 corrected by surgery), and there were 2 multiple intra-hepatic strictures. There was hepatic artery thrombosis in 5, including 4 children. In 3, grafts were salvaged by thrombectomy and 2 others underwent re-transplantation. In those who survived transplantation by more than 1-month, recurrent hepatitis B was seen in 6 of 17 (35%) and recurrent hepatitis C in 12 of 19 (63%).

Thus, results of our first 100 liver transplants are similar to those reported by larger centers, showing that in an appropriate setting good results can be achieved by small transplant programs.

Testicular cancer is the most common malignancy in young men. To evaluate knowledge and awareness of that cancer, and of the practice of testicular self-examination (TSE), we developed a questionnaire which was distributed to 717 male soldiers and 200 of their military physicians.

21% of the soldiers had received some explanation of the importance of TSE, but only 16% were actually instructed how to perform TSE, and only 2% practiced it regularly. 24% had never examined their testicles before, 185 only rarely, and 6% often. With increased age, TSE frequency increased, but previous education, type of military unit, and ethnic origin had no affect. 99% of military physicians had been taught how to examine breasts, but only 70% had been taught routine testicular examination. 22% performed it, but 27% never did. 84% had never taught their soldiers the importance of TSE, although 51% taught female soldiers breast self-examination.

There was a significant lack of awareness of the importance of regular practice of TSE among both soldiers and their army physicians.

Prevalence of hip fractures is increasing world-wide, as the mean age of populations increases. Despite advances in anesthesia, nursing care, and surgical techniques, hip fractures remain a significant cause of morbidity and mortality in the elderly.

We operated on 65 cases of hip fractures from 1995 to the end of 1997: average age was 82.9, 72% were women, average waiting time for operation was 1.6 days, perioperative mortality was 3.5% and postoperative mortality 26.2%.

Cholangiocarcinoma accounts for about 1% of all malignant tumors. They are difficult to diagnose because of their small size and their location. Although surgical resection is the best therapeutic approach, most patients undergo unnecessary exploratory laparotomy due to incorrect preoperative diagnosis.

We present our experience with laparoscopic ultrasound (LU) in the evaluation of cholangiocarcinoma and determination of tumor spread and vascular involvement. Of 25 patients referred for surgery, 6 were excluded following LU and were referred instead for palliative treatment. Diagnosis of the tumor was successful in 92%, and vascular involvement was diagnosed in 46%. LU should be an integral diagnostic test in the evaluation of choriocarcinoma.

Opinions of the National Health Insurance (NHI) Law held by primary care physicians were surveyed. A questionnaire was submitted (April-July 1997) to 930 primary care physicians employed by sick funds, including general practitioners, family physicians, pediatricians and internists. Response rate was 86%.

They supported the main components of the NHI law. It was considered desirable "to a great" or "very great extent" to allocate funds to sick funds based on age and number of members (76%), to require them to accept all applicants (72%), to designate a uniform basket of services (65%), to allow members to transfer freely between funds (63%), and to allow sick funds to sell supplemental insurance (59%). However, only 41% were satisfied with the implementation of the law.

Multivariate analysis showed that employment by Maccabi, Meuhedet, or Leumit sick funds had an independent effect on low satisfaction with the law as implemented, and on negative opinions about the uniform basket of services, the accepting of all applicants, and allocation of funding based on age and number of members. Those employed by the Maccabi and Meuhedet funds were in favor of allowing sick funds to sell supplemental insurance.

The findings of the study have implications for policy-makers interested in increasing support for national health reform by physicians. It is important to examine possibilities of developing direct channels of communication between national policy-makers and physicians, as well as institutionalizing mechanisms that involve physicians directly in formulation of national policy.

We assessed the incidence of drug abuse among patients requiring psychiatric hospitalization, and characterized the population at risk. The data on drug abuse were obtained from self-reports and urine tests in 103 patients, aged 18-65, hospitalized in the Kfar Shaul Psychiatric Hospital (autumn 1998).

There was close correspondence between the self-reports and the results obtained from urine tests. 1/3 admitted to having used illegal drugs and signs of drug abuse were found in about 1/4 of the urine tests. The most prevalent drugs were cannabis products (hashish and/or marijuana) and in 15 patients opiates.

Drug users were younger than non-users. With regard to psychiatric symptomatology, fewer negative symptoms were recorded among cannabis abusers with schizophrenia, compared to schizophrenic patients with no history, past or present, of cannabis abuse.

The present findings confirm the clinical impression that there has been an increase in drug abuse among mental patients, parallel to that found in society at large. Confirmatory surveys are necessary. Our findings clearly suggest that a change in attitude has occurred in Israel to what has been considered a marginal problem. Hospitalized mentally-ill patients, the younger in particular, should be considered at risk for drug abuse.
