Osteoid Osteoma of the Hand: a Rare Location

Nahum Rosenberg, Shalom Stahl

Dept. of Orthopedics A, and Hand Surgery Unit, Rambam Medical Center, Haifa

Osteoid osteoma is a benign bone tumor. It is rare in the hand where it may cause local swelling and pain. Marginal resection is almost always curative, without residual functional disability. Because it is rare in this location, osteoid osteoma is not usually considered in the differential diagnosis of painful lesions of the hand, which may delay treatment. Osteoid osteoma in the hand has characteristic clinical, roentgenologic and scintigraphic features. Early diagnosis of this lesion may be improved by recognition of these features. An algorithm for decision-making that may help is proposed. We describe our experience in 3 cases involving, respectively, the capitate bone, a proximal, and a distal phalanx, in which cases marginal resection was curative.

Acute appendicitis is the most common surgical problem in pregnancy, when it is difficult to diagnose early because of the physiological changes of pregnancy. We studied the problem in the Negev population and present the main issues in diagnosis and management. Between 1988-96, 26 women were operated on for acute appendicitis during pregnancy (1/3297 deliveries), 3 by laparoscopy. In 13 there was a histopathological confirmation of the diagnosis. Clinical diagnosis was more accurate in the first trimester of pregnancy than in the second or third (p=0.073). Premature delivery rate was higher in both confirmed and unconfirmed acute appendicitis than in other pregnancies (p<0.00001), but without significant differences between the 2 groups with appendicitis. Other indexes of maternal and perinatal morbidity did not differ either.

6 cases of popliteal vascular trauma are presented, 3 due to posterior dislocation of the knee and 3 due to crush injury. The patients were referred from another hospital and some had undergone unnecessary angiography when ischemia was present, leading to delay in surgery. All patients presented with distal ischemia and underwent reconstructive surgery; 2 subsequently underwent below-knee amputation because of irreversible ischemia and sepsis.

Urgent operation for popliteal vascular trauma is necessary whenever there is ischemia and intraoperative angiography may be necessary. There should be reconstruction of the artery and vein when there is concomitant venous damage, and fasciotomy and debridement are important. The harmful potential of occult popliteal vascular injuries and their ostensible mild presentation present a challengfor the emergency room surgeon.

Splenic artery aneurysm is an uncommon form of vascular disease of unknown etiology. Its clinical importance is due to its high mortality, especially in pregnancy, when maternal mortality is 70% and fetal mortality 95%. Most cases of splenic artery aneurysm are asymptomatic and are diagnosed incidentally. We present a woman with incidentally diagnosed splenic artery aneurysm in whom the splenic artery and its aneurysm were resected.

We review various theories of the pathogenetic mechanisms of steroid-induced and essential hypertension. We investigated the possibility that a pathogenetic mechanism leading to glucocorticoid (GC)-induced hypertension or to mineralocorticoid (MC)-induced hypertension, or both, may be of critical importance in primary hypertension. We studied plasma levels of corticosterone (BK) and aldosterone (Aldo), and their concentrations in arterial and renal tissues of spontaneously hypertensive rats (SHR), a model of primary hypertension, and in the antecedent strain WKY rats as a normotensive control. Plasma levels of BK and Aldo were found to be normal and identical in SHRs and WKYs. Tissue (intracellular) levels of BK were more than double in SHRs than in WKYs. Subsequently we examined the activity of 11b-hydroxy steroid dehydrogenase (11-HSD) in both aortic and renal tissues of SHRs and WKYs. 11-HSD converts BK to the corresponding 11-keto compound, 11-dehydro-corticosterone (cpd.AK), which is inactive, in view of its inability to bind to the MC receptors (and also to the GC receptors). BK, the main glucocorticoid in the rat, as well as cortisol, have high affinity for the MC-receptor (MR). Normally BK or cortisol are present in 10²-10³ times greater concentrations than Aldo in tissues possessing MR. The enzyme 11-HSD deactivates BK (or cortisol), thus protecting MC-receptors in the MC target tissues from being activated by GC. When we examined arterial and renal tissue activities of 11-HSD in SHRs, the activity of 11-HSD was only one-third that found in the WKY rats. This explained higher levels of BK in the tissues of SHR, and suggested that decreased activity of 11-HSD is a pathogenetic factor for hypertension in SHRs.

Thus, in a model of primary hypertension such as SHR, decreased activity of 11-HSD in the target tissues of MC appears to lead to glucocorticoid-induced mineralocorticoid hypertension.

As laparoscopy becomes more prevalent, it is being used for a growing variety of abdominal operations, both electively and as emergency treatment. We describe our preliminary experience in laparoscopic repair of perforated duodenal ulcer. 2 women and 2 men, aged 40-78 were operated over a period of 4 months and in all laparoscopic suture and omentopexy were performed with meticulous abdominal lavage. Despite somewhat longer operative time but a similar period of hospitalization, the easier post-operative course and fewer wound complications justify this technique. The effectiveness of medical treatment of peptic disease, and especially the anti-Helicobacter pylori regimen, supports the view that closure of the perforation is usually enough, and vagotomy is not needed.

A 15-year-old girl, who had been treated with minocyclin for acne for 2 months, was admitted for investigation of headache, nausea and papilledema. A space-occupying lesion was ruled out by computerized brain tomography. The diagnosis of benign intracranial pressure (pseudo-tumor cerebri) was made because of elevated cerebrospinal fluid pressure with normal biochemistry and cytology. Tetracyclines, especially minocyclin, commonly used for treating acne in adolescents, can cause benign intracranial pressure.

Ebstein anomaly is a rare congenital disease which affects location, structure and mobility of the tricuspid valve, and right atrium and ventricle. Although most cases are sporadic, familial occurrence has been reported. We report 2 brothers born with Ebstein anomaly. The parents were first degree cousins and there were 8 other children. 2 daughters were born with other congenital heart anomalies, 1 with ventricular septal defect and the other with severe pulmonary artery stenosis. We suggest that in some families, Ebstein anomaly is an autosomal dominant disease with different expression in the sexes.

Kimura's disease is a rare angiolymphoid proliferative disorder of soft tissue characterized by subcutaneous swelling and a predilection for the head and neck. There are usually enlarged regional lymph nodes, eosinophilia and elevated sedimentation rate and IgE levels. A 26-year-old women with subcutaneous masses in the submandibular area is reported. The diagnosis of Kimura's disease versus angiolymphoid hyperplasia is discussed.

Dept. of Orthopedic Surgery, Carmel Medical Center, Haifa

Between 1933-1995, 16 patients underwent conversion-total hip replacement after internal fixation of an intertrochanteric fracture failed. Clinical results were unsatisfactory compared to primary total hip replacement. There was a high incidence of intra- and postoperative complications, including femoral fracture, wound infection, and aseptic loosening. This study should increase the surgeon's awareness of the difficulties encountered in conversion of failed intertrochanteric fractures to total hip replacement.

Polyunsaturated fatty acids (PUFA) are vital for the normal development of the brain and the eye retina in infancy. Breast milk contains significant amounts of PUFA, and compensates for their low production in infancy. Only recently a few companies with worldwide product distribution have started to enrich infant formula with PUFA. We evaluated the safety and clinical efficacy of a locally made PUFA-enriched infant formula, produced for the first time in Israel.

50 normal, full term infants participated in a prospective, randomized double-blind study. Half received a regular whey-predominant infant formula (Materna Plus), and the other half a PUFA-enriched formula (Materna Premium), both produced in Israel, for 30 days. Evaluation included physical examination, growth parameters, stool analysis, daily parental questionnaires regarding infant behavior and defecation, and developmental assessment.

There were no significant differences on comparing growth parameters, infant behavior, attacks of restlessness, gas severity, or stool characteristics in the 2 groups. There were no side effects or abnormal stool findings in either group, and no differences in developmental assessment at 3 months of age.

We conclude that the locally-produced PUFA-enriched infant formula is safe and clinically efficient. We assume that the lack of any effect on developmental indices is due to the relatively short exposure to the PUFA-enriched diet. Nevertheless, based on the recent literature, there is no doubt that PUFA supplementation isvital in improving infant brain and eye development.

Islet cell antibodies (ICA) continue to serve as the basis of the principal serological test for definition of active autoimmunity of beta-cells. Its disadvantages are the need for human pancreatic tissue and difficulty in obtaining quantitative results. In the past decade biochemically-defined beta-cell antigens were described, leading to the development of sensitive and specific autoantibody assays, to predict insulin-dependent diabetes mellitus (IDDM). We examined the value of combined biochemically-based serological assays, such as autoantibodies to insulin (IAA), glutamic acid decarboxylase (GADA) and ICA512 (ICA512A) to replace the traditional ICA assay.

Blood samples of 114 newly diagnosed IDDM patients, aged 12‏5 yrs (range 2 months - 29 years) were tested for ICA (indirect immunofluorescence), IAA, GADA and ICA512A (radiobinding assay). The latter 2 assays were performed using recombinant human [35S]-labeled antigen produced by in vitro transcription/translation. We found that fewer sera scored positive for ICA and/or IAA (80.7%, 92/114) than for 1 or more of IAA, GAD, or ICA512 (88.6%, 101/114). We conclude that combined testing for IAA, GAD and ICA512 can replace the traditional ICA/IAA test to predict IDDM and is helpful in the differential diagnosis of insulin-dependent and noninsulin-dependent diabetes.

Cyclic vomiting syndrome in children is a manifestation of various etiologies, including gastroenterological and renal disorders, central and autonomic nervous system abnormalities, as well as metabolic and endocrine dysfunction. Frequently no organic cause is found. Personality profiles of children with cyclic vomiting reveal perfectionism, competitiveness, and aggressive behavior. Vomiting attacks have been induced by anxiety and excitement in patients with cyclic vomiting. We describe an 8-year-old girl with cyclic vomiting, frequently associated with occipital headaches, photophobia or dizziness. Psychiatric evaluation indicated a generalized anxiety disorder.

Sudden death from asthma is rare but occurs in the young age group. We recently faced this rare situation, when 3 asthmatic children were dead on arrival at the local emergency room. All 3 had been treated with beta-2 agonist inhalation on a regular basis, without anti-inflammatory treatment. 2 of the children died while inhaling the beta-2 agonist. It is important that there be clear guidelines and full education about the management of asthma, during and between exacerbations, to prevent such deaths.

Acute hyperparathyroidism is a rare and dangerous condition. It is supposed to result from transformation of a mild chronic form into an acute and stormy illness. The causes and the mechanism of such a transformation are usually unknown. A case of acute hyperparathyroidism is presented in which hemorrhage into a parathyroid adenoma was recognized and diagnosed as the immediate cause of the transformation from the mild long-standing form of the disease into the severe acute form.
