לאדם, כמו ליונקים אחרים, מנגנון ויסות-טמפרטורה שנועד לשמר את טמפרטורת הגוף בטווח המאפשר פעילות פיזיולוגית תקינה. בגיל הזיקנה, משתבש מנגנון זה ואיננו יעיל כמו בגיל צעיר. לשיבוש זה סיבות אפשריות אחדות, וקיימים חילוקי דעות בין החוקרים על המשמעות של חלק מהן.

חשיבות המערכת הוורידית והחזר הדם ללב האדם הבוגר ידועה זה שנים. למעשה, השליטה העיקרית בתפוקת הלב הבוגר נקבעת על פי שינויים בזרימה ובהחזר הוורידיים. מדידות לחצים וזרימות במערכת ההחזר הוורידי ללב, משמשים כלי ניטור יומיומי ביחידות לטיפול נמרץ וטיפולים תרופתיים רבים מיועדים לשיפור זרימה זו במצבי אי-ספיקת לב. עם זאת, הזרימה העוברית וההחזר הוורידי ללב העובר לא נחקרו עד לשנים האחרונות. הסיבה לכך כפולה. ראשית, דגם עובר הכבש לבדיקת זרימת הדם שפותח בשנות השישים ייצג בעיקר, את המערכת העורקית. שנית, זיהוי מדויק של מערכת הזרימה הוורידית קשה יותר טכנית ורק עם פיתוח שיטת דופלר בצבע, ניתן היה להדגים ולמדוד בוודאות את צורת גלי הזרימה של מרכיבי המערכת ולדגום אותם. התפתחות נוספת בשנים האחרונות נובעת מהדגמה מדויקת יותר של המערכת ומאפשרת מדידת זרימת הדם במונחי מ"ל/דקה.

Intraventricular hemorrhage in full-term neonates is rare; it may develop without any clinical signs. Its cause is not fully understood although some risk factors have been identified. A higher index of suspicion would ensure earlier diagnosis and treatment, which might reduce the rate of severe complications. We describe 2 cases in full-term neonates.

Tuberculous Meningitis in HIV

Medical Dept., Hadassah University Hospital, Ein Karem, Jerusalem

The increase in prevalence of tuberculous meningitis during the past decade has been attributed in part to the increase of AIDS. Failure to diagnose HIV can cause irreversible damage and even death. We describe a man with AIDS admitted through the emergency room because of high fever and headaches for more than a month, He was cachectic and had nuchal rigidity without major neurological deficit. Brain imaging was normal and lumbar puncture showed neutrophils, lymphocytes, hypochloremia, elevated protein, and decreased glucose; cryptococcal antigen was negative but acid-fast staining was positive.

Anti-TB chemotherapy was started using 4 drugs and dexamethasone was also given. Considerable improvement in his general condition followed rapidly.

Use of corticosteroids in tuberculous meningitis has been a major issue. They are added to antimicrobial agents in order to decrease reactivity of inflammatory mediators and thus reduce central nervous system damage.

We review several controlled studies in which steroids were added to treat tuberculous meningitis. The conclusions of most were that they decrease morbidity and mortality, especially of those moderately to severely ill. Most considered as ungrounded the possibility of exacerbating latent tuberculous, or any other opportunistic infection outside the central nervous system. However, it is currently recommended to add prednisone, 1 mg/kg/d for 2-4 weeks when initiating antituberculous treatment.

Surgery for Blepharoptosis in Muscular Dystrophy

In some muscular dystrophies there is ocular involvement characterized by blepharoptosis and ophthalmoplegia. These conditions occur in chronic progressive external ophthalmoplegia, oculopharyngeal muscular dystrophy, mitochondrial myopathy, myotonic dystrophy, and ocular myasthenia, among others. Although they differ in their systemic clinical manifestations and in genetic inheritance, ocular involvement is common to all of them. Manifestations include bilateral progressive blepharoptosis with or without extraocular muscle malfunction.

During surgical repair of the ptotic eyelid, consideration must be given to eyeball movements, in addition to maximal eyelid elevation, and to avoiding overcorrection and consequent corneal overexposure, leading to dryness and visual impairment. With these muscular dystrophic disorders, resection of the levator muscle or blepharoplasty alone does not suffice. Follow-up shows that most patients need a secondary repair after a short while. Operative correction uses a frontalis sling for eyelid elevation and support.

A series of 8 patients with these diseases, operated on by various surgical techniques during the past 7 years, is presented.

Tuberculous Meningitis in Review

Tuberculosis meningitis is one of the most dangerous forms of tuberculosis (TB). Due to large waves of immigration, the incidence of TB in Israel has increased in recent years, as has that of TB meningitis. Due to its high mortality, rapid diagnosis of TB meningitis is of paramount importance.

We present a patient admitted with a acute febrile disease which was subsequently diagnosed as TB meningitis.

Endoscopic Sinus Surgery for Extracranial Complications of Sinusitis

E. Deutsch, I. Hevron

ENT Dept., Bikur Cholim Hospital, Jerusalem

Orbital subperiosteal abscess (SPA) and Pott's puffy tumor (PPT) are the major extracranial complications of acute sinusitis. These complications are aggravated by the close anatomic relationships between the nasal sinuses and the orbits and frontal bone. Furthermore, the rich diploic venous drainage of the region enhances the spread of the infection.

Between 1992 and 1997, 16 patients (mean age 12 years, range 2-15, 10 of them males), 11 of them with SPA and 4 with PPT were operated on by the senior author by means of endoscopic sinus surgery (ESS). Indications for operation included: CT findings of abscess formation and lack of clinical improvement after 48 hours of IV antibiotic therapy. Clinical resolution of symptoms was achieved in all and there were no operative or postoperative complications.

We emphasize and explain the advantages of ESS over external approaches in surgery for extracranial complications of acute sinusitis by several facts: the technique treats the source of the disease, clinical success rate is high, morbidity is low, and facial distortion and poor cosmetic results completely avoided.

Sacrospinous ligament fixation is a well-known method for correction of vaginal vault prolapse. The procedure is primarily indicated after hysterectomy and as a prophylactic measure for total uterine prolapse.

8 women with post-hysterectomy vaginal vault prolapse aged 48-72 years, were referred 1-25 years following primary surgery. Sacrospinous ligament fixation was elected to enable simultaneous correction of cystocele and rectocele, and to preserve sexual function. All operations were completed without significant complications.

In 6 of the 8 patients located for long-term interview, 1 reported mild bulging of the introitus, another mild urinary stress incontinence, urgency and frequency and 1 reported frequency only. Sexual function in 4 was without complaints. Defecation in all patients was normal.
We conclude that this operation is safe and effective. We encourage gynecologic surgeons to consult an experienced tutor prior to performing this procedure, as this type of surgery is quite dangerous and many gynecologists are not familiar enough with it.

Laparoscopic adrenalectomy has recently been shown to be safe and effective for a variety of benign adrenal tumors, such as aldosterone adenoma, pheochromocytoma, nonfunctioning adenoma, Cushing's adenoma and Cushing's syndrome. Recently, laparoscopic surgeons adopted an extraperitoneal approach in which a space is created by the introduction of a trocar with an inflatable balloon tip. This technique with a minimal access procedure provides direct access to the adrenal glands without interfering with intraperitoneal organs.

Laparoscopic adrenalectomy using the extraperitoneal approach was completed in 18/20 consecutive patients. Mean operative time was 95 min (range 80-120) and median hospital stay 3 days. Blood transfusion was not required, and there were no postoperative complications.

Cervical pregnancy is a rare but serious complication. The most frequent presenting symptom is vaginal bleeding, and is thus common in inevitable abortion. Examination reveals a dilated cervix containing products of conception derived from the emptied uterine cavity. The pathologic criteria are cervical glands opposite the placental site, attachment to and actual invasion of the cervix by the placenta, a portion of the placenta below the posterior reflection, and no fetal parts in the corpus uteri. Treatment ranges from hysterectomy to treatment with chemical agents, mostly methotrexate. We present a case of ectopic, cervical pregnancy with exaggerated placental site in the cervix.

2 cases of malaria in family practice are described in a 26- and a 50-year-old woman. Both probably could have been prevented had common chemoprophylactic drugs been taken. The risk of malaria is greater than the risk of possible side-effects of the drugs commonly used by travelers for prevention. Family physicians must be aware of the possibility of malaria in young people with fever, especially those who have travelled to equatorial areas and special attention should be given to encourage chemoprophylaxis.

Increased fetal muchal translucency (NT) thickness at 10-14 weeks of gestation may indicate underlying fetal chromosomal abnormalities, anatomical anomalies and genetic syndromes. Between January 1997 and May 1998, 1400 women 10-14 weeks pregnant underwent sonographic screening for detection of Down's syndrome (DS). Follow-up was complete in 1208 (86%).

Maternal age ranged from 17-44 years (mean 18.0). 87% were found by screening to have a higher risk (1:380) for DS diagnosed at birth. All these fetuses were karyotyped and 8 had chromosomal abnormalities. 2 fetuses with normal NT were diagnosed later as having DS, 1 by the mid-gestation triple test and 1 by amniocentesis because of advanced maternal age.

Thus sonographic screening identified 8 out of 10 fetuses found to have chromosomal abnormalities at birth. Neonates not karyotyped before birth had no traits at birth that justified chromosomal analysis. Results of this study suggest that NT measurement, combined with maternal age, is an effective 1st trimester screening method for DS in an unselected obstetric population.
