The authors report 100 cases with prolonged spinal muscular atrophy (SMA) and survival beyond 4 years old. There were 46 boys and 54 girls. 23 of them had histories with an autosomal recessive form of inheritance. One case had a dominant form. The unity of cases described as Werdnig Hoffman disease [SMA I, SMA II (Childhood), ans SMA III (Kugelberg Welander)] is supported and our cases fell in three groups according to their ambulatory capabilities: never acquired, lost, or retained. 71 cases have never walked: the onset of symptoms was noted at an average age of 6.4 months +/- 3; the average age at the last examination was 16 years (4-39). Death occurred in 6 cases. Loss of walking occurred in 24 cases: the onset of symptoms was noted at an average age of 17.4 months +/- 14.2. 5 cases were still ambulatory: the onset of symptoms was noted at an average age of 2.4 years +/- 2.8. For these last 29 cases the average age at the last examination was 20 years (4-38); death occurred in two cases. The weakness was symmetrical and proximal. The period of worsening varied but, frequently, patients with a later onset of symptoms had a longer period of deterioration. Tongue fasciculations were present in all cases who never walked. Facial and masseter weakness occurred in 3 cases. Oesophagus dyskinesia and distension of the stomach due to brain stem lesions occurred in many cases. This brain stem damage was responsible of 2 sudden deaths (8-30 years). Premature puberty occurred in 14 cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Oculopharyngeal muscular dystrophy is a hereditary pathology transmitted in an autosomal dominant manner. The clinical symptoms are palpebral ptosis, oropharyngeal dysphagia and proximal limb weakness. Upper gastro-esophageal endoscopy is recommended to study the dysphagia, a video-radiology study with barium and an esophageal manometry to study the pharyngeo-esophageal motor disorder. Muscle biopsy reveals the presence of atrophic fibers substituted by an increase in fat and connective tissue. In 1998 Brais described the genetic alteration responsible for this pathology, a limited expansion of the triplet of GCG nucleotides in PABP2 gene on chromosome 14q11. Normal individuals have the homozygotic form (GCG)6 of this triplet, whereas patients with the described syndrome have the heterozygotic form (GCG)6-(GCG)9 or (GCG)6-(GCG)10. We present three siblings from the same family with diagnoses and genetic confirmations of oculopharyngeal dystrophy. Two of the patients underwent cricopharyngeal myotomy to relieve the dysphagia.

We report the case of a 63-year-old man who presented with weakness, fatigue, dehydration, confusion, abdominal pain, congestive heart failure and hypercalcemia. He expired and autopsy revealed an exulcerating carcinoma of the esophagus, invading the esophageal wall and metastasizing to the lungs, skin and lymph nodes. Histology demonstrated an epithelial tumor consisting of two components with transition between the two. One component was a keratinizing squamous cell carcinoma, whereas the other component consisted of pleomorphic small cells. The hypercalcemia was assumed to be due to parathyroid hormone related protein (PHRP), which was demonstrated by immunohistochemistry only in the pleomorphic small cells and not in the squamous cells. PHRP induced humoral hypercalcemia of malignancy is most often associated with squamous cell carcinomas. The finding that in our case, the pleomorphic small cell component was PHRP immunopositive and the squamous cell component showed no immunoreactivity, is intriguing and remains unexplained.
