[Wolfram syndrome. Personal experience].

We report on a young patient who suffered from diabetes mellitus and neurosensorial deafness from the age of two. One year later she was noted to have deteriorated vision and the diagnosis of optic atrophy was made, her visual acuity decreased progressively. At the age of six she was admitted to our hospital because of thiamine responsive megaloblastic anemia, a rare clinical feature of Wolfram's syndrome (only 13 cases have been reported to date). Thiamine (75 mg/day) was commenced at a single oral dose with a rapid increase of Hb level after a few days of therapy. The insulin requirement didn't decrease during thiamine therapy, the C-peptide level after glucagon remained almost indosable. No improvement was observed in the deafness and in the optic atrophy. These findings suggest that diabetes mellitus and optic atrophy, in Wolfram's syndrome are not related to thiamine metabolism.

Cerebro-facio-articular syndrome of Van Maldergem: confirmation of a new MR/MCA syndrome.

Van Maldergem et al. (1992) described a new syndrome in an 11-year-old girl, characterized by: mental retardation, hypotonia, dysmorphic facies with telecanthus, epicanthus, broad flattened nose, large inverted W-shaped mouth, malformed ears, finger camptodactyly, and joint hyperlaxity. In this report we present a 5-year-old girl with very similar clinical findings. We confirm the existence of this condition as an independent clinical entity, and we propose that, based on the major clinical manifestations, it should be defined as "cerebro-facio-articular" syndrome.

Variability of the Brachmann-de Lange syndrome.

Brachmann-de Lange syndrome (BDLS) is a relatively common multiple congenital anomaly/mental retardation syndrome, whose cause is unknown. The clinical variability of this condition is well-known. Recently some reports suggested the possible existence of a mild BDLS phenotype. We report on 30 patients in whom a diagnosis of BDLS was made or strongly suspected in 12 different Italian hospitals. Based on clinical evaluation we divided them into two groups, classical and mild BDLS cases. We compare the clinical data of these patients and we discuss the problems which arise in trying to define clear criteria of distinction between these two groups.

Costello syndrome: further clinical delineation, natural history, genetic definition, and nosology.

In 1977 Costello described two unrelated children with poor postnatal growth, mental retardation, curly hair, coarse face of similar appearance, and nasal papillomata, suggesting the existence of a previously undescribed syndrome of uncertain familial nature [Costello, Aust Paediatr J 13: 114-118, 1977]. The existence of this syndrome as a separate entity was substantiated several years later by two additional reports by Der Kaloustian et al. [Am J Med Genet 43:678-685, 1991] and Martin and Jones [Am J Med Genet 41:346-349, 1991]. More recently Borochowitz et al. [Am J Med Genet 43:678-685, 1992] described a new "multiple congenital anomalies/mental retardation syndrome with facio-cutaneous-skeletal involvement." Whether this condition should be considered separately from the Costello syndrome is currently a matter of debate. We present three cases, two of whom are sibs, who support the identity of the two syndromes. Our aim is to better redefine the diagnostic criteria, describe the natural history, and confirm the genetic cause of the Costello syndrome, whose pattern of inheritance is most likely autosomal recessive.

Antiepileptic drug therapy and congenital defects.

The present paper is a literature review on congenital malformations observed in the offspring of epileptic mothers. The conditions which are here considered are both morphologic and functional defects. To prevent one or more of these defects it is essential to understand the precise etiologic role of the antiepileptic drugs, which seem to be of primary importance, and their mechanism of action, as drug therapy cannot be stopped during pregnancy being indispensable for the well-being of the mother and fetus. At this state of knowledge a proportion of defects can be prevented if optimal therapy is followed right from the preconceptional period: to this end, a set of guidelines is suggested and discussed.

New XLMR syndrome with characteristic face, hypogenitalism, congenital hypotonia and pachygyria.

A previously unreported X-linked MCA/MR syndrome is described in 4 members of a large family. Phenotypic manifestations include mental retardation, microcephaly, failure to thrive, severe congenital hypotonia, characteristic face, hypogenitalism, pachygyria. This appears to be an X-linked dominant trait with decreased penetrance and expressivity in carrier females.

On the symmetry of limb deficiencies among children with multiple congenital anomalies.

In humans, unpaired organs are placed in a highly ordered pattern along the left-right axis. As indicated by animal studies, a cascade of signaling molecules establish left-right asymmetry in the developing embryo. Some of the same genes are involved also in limb patterning. To provide a better insight into the connection between these processes in humans, we analysed the symmetry of limb deficiencies among infants with multiple congenital anomalies. The study was based on data collected by the International Clearinghouse for Birth Defects Monitoring Systems (ICBDMS). Registries of the ICBDMS provided information on infants who, in addition to a limb deficiency, also had at least one major congenital anomaly in other organ systems. We reviewed 815 such cases of which 149 cases (18.3 %) were syndromic and 666 (81.7 %) were nonsyndromic. The comparisons were made within the associated limb deficiencies, considering the information on symmetry, using a comparison group with malformations associated not involved in the index association. Among the non-syndromic cases, the left-right distribution of limb deficiencies did not differ appreciably between limb deficiency subtypes (e.g., preaxial, transverse, longitudinal). The left-right distribution of limb anomalies did not differ among most types of non-limb anomalies, though a predominance of left-sided limb deficiencies was observed in the presence of severe genital defects - odds ratio [OR], 2.6; 95 % CI, 1.1-6.4). Limb deficiencies (LDs) were more often unilateral than bilateral when accompanied by gastroschisis (OR, 0.1) or axial skeletal defects (OR, 0.5). On the contrary, LDs were more often bilateral than unilateral when associated with cleft lip with or without cleft palate (OR, 3.9) or micrognathia (OR, 2.6). Specifically, we found an association between bilateral preaxial deficiencies and cleft lip, bilateral amelia with gastroschisis and urinary tract anomalies, and bilateral transverse deficiencies and gastroschisis and axial skeleton defects. Of 149 syndromic cases, 62 (41.6 %) were diagnosed as trisomy 18. Out of the 30 cases of trisomy 18 with known laterality, 20 cases were bilateral. In the remainder the right and left sides were equally affected. Also, in most cases (74.4 %) only the upper limbs were involved. In conclusion the left-right distribution of limb deficiencies among some non-limb anomalies may suggest a relationship between the development of the limb and the left-right axis of the embryo.

Second case of hepatoblastoma in a young patient with Simpson-Golabi-Behmel syndrome.

Simpson-Golabi-Behmel syndrome (SGBS) is an X-linked overgrowth syndrome associated with multiple congenital anomalies caused by a mutant X-linked recessive trait. The authors report on a 14-month-old male patient affected by hepatoblastoma. As far as is known, this is the second patient reported with SGBS and hepatoblastoma. The observations emphasize that an increased risk of neoplasia in SGBS must be kept in mind, especially in young patients.

Hepatic intra-arterial chemotherapy using a percutaneous catheter in pretreated patients with metastatic colorectal carcinoma.

BACKGROUND: Hepatic intra-arterial chemotherapy (HIAC) leads to a higher response rate than systemic administration in untreated patients with liver metastases from colorectal cancer (CRC). The aim of this study was to evaluate the activity and safety of giving HIAC through a percutaneous catheter in pre-treated patients. PATIENTS AND METHODS: Forty-five CRC patients with liver-only or liver-dominant metastases, resistant or refractory to previous systemic therapy, were treated using a temporary trans-subclavian catheter. A 3-day chemotherapy regimen of daily 5-fluorouracil (5-FU) 1000 mg/m2/day + heparin 5000 IU/day given as a 24-hour continuous infusion, and twice daily bolus injections of cisplatin (CDDP) 10 mg/m2 and mitomycin C (MMC) 2 mg/m2, was administered every six weeks. RESULTS: One hundred and seventeen courses were administered to 45 patients (a median of three per patient: range 1-5). Of the 44 patients evaluable for response, 16 (35%) had a partial response, 15 (33%) stable disease and 12 (26%) progressive disease. Eleven of the 16 responding patients had been refractory to a previous 5-FU-based systemic therapy. The most relevant grade 3-4 toxicities included neutropenia (22%) and thrombocytopenia (15%). Gastro-duodenal ulcers occurred in nine patients. Catheter displacement was recorded during 22 out of 117 (18%) courses. CONCLUSION: HIAC with 5-FU, CDDP and MMC given through a temporary percutaneous catheter is safe and active in pretreated patients with metastatic CRC. Iatrogenic gastroduodenal ulcers are a serious but manageable complication.
