Articular-sided rotator cuff tears: which is the best repair? A three-year prospective randomised controlled trial

Purpose

To compare two groups of patients who underwent two different arthroscopic procedures for repair of articular-sided partial-thickness rotator cuff tears (PTRCTs).

Materials this is a comparative prospective study of two methods for repair of partial cuff tears

Thirty-two patients underwent arthroscopic rotator cuff repair with a transtendon technique (group 1); 28 underwent arthroscopic full-thickness conversion and repair of the lesion (group 2). ROM measures, clinical findings, MRI features (tendon healing and re-tear), Constant–Murley and ASES scores were assessed pre- and postoperatively and compared. Patients were also asked about return to sport and level of activity.

Results

At the last appointment, patients of both the groups were significantly improved for clinical findings, ROM measures, imaging features, Constant–Murley and ASES scores than at baseline, without any significant inter-group difference. In group 1, 15 of 20 patients (75 %) who practiced recreational sport activities had returned to sport at the same level as before the onset of symptoms, without any discomfort. In group 2, 12 of 18 patients (67 %) had returned to the same level of sport activity they practiced before symptoms. At the last follow up, MRI showed rotator cuff healing in 31 patients of Group 1 and 27 patients of Group 2 (p = 0.83).

Conclusions

The two procedures are safe, effective, and comparable.     

Use of antipsychotics and long-term risk of parkinsonism

Neurological Sciences - Few epidemiological studies have assessed the risk of parkinsonisms after prolonged use of neuroleptics. We aimed to examine the long-term risk of degenerative parkinsonisms...

Improvements in hepatic parenchymal transection for living related liver donor

INTRODUCTION: To eliminate mortality and morbidity risk in living related liver donors, we developed a new surgical technique to resect hepatic parenchyma using an ultrasonic surgical aspirator in association with a monopolar floating ball cautery. METHODS: We performed 17 right hepatectomies and 2 left hepatectomies using this technique. We performed a retrospective analysis of perioperative mortality, length of hospitalization (LOS), blood transfused during surgery (IBT), intraoperative blood lost (IBL), biliary complications (BC), and aspartate aminotransferase (AST)/alanine aminotransferase (ALT) peak in the first postoperative week. This group of patients (Group A) was compared, using the analysis of variance (ANOVA) test (P < .05) with 2 different groups of 19 patients: Group B with liver neoplasms that had the same technique as Group A, and Group C wherein a crushing clamp technique was used. RESULTS: All of the analyzed variables showed significative statistical differences, especially between Group A and Group C (IBL, P < .000; IBT, P < .006; LOS, P < .028; BC, P < .000; AST peak, P < .041; and ALT peak, P < .023). DISCUSSION: The association of these 2 techniques seems to reduce the LOS, and the need for intraoperative blood transfusions. Moreover, the surgical complications (biliary leaks) and the postoperative parenchymal cytonecrosis seem to be less using this technique.     

Can clinical signs identify newborns with neuromuscular disorders?

OBJECTIVE: To evaluate retrospectively the prevalence of neuromuscular disorders in 83 newborns referred to a tertiary care center because of hypotonia and weakness and/or contractures, with a possible diagnosis of neuromuscular disorder. We also aimed to establish whether clinical signs could help to identify infants with neuromuscular disorders. STUDY DESIGN: Sixty-six of the 83 infants who fulfilled the inclusion criteria (79.5%) had an identifiable disorder, which was a neuromuscular disorder in 39 (46.9%). RESULTS: Absent or extremely reduced antigravity movements were mainly found in infants with neuromuscular disorders (sensitivity and specificity 97.4% and 75%), whereas partial range antigravity movements were more frequent in infants with other diagnosis. Contractures were mainly found in infants with peripheral nerve or muscle involvement but also were relatively frequent in infants with genetic or metabolic syndromes (sensitivity 69.2%, specificity 61.3%). Reduced fetal movements and abnormal liquor were frequent but not present consistently in infants with neuromuscular disorders (sensitivity 46.1% and 38.4%) and were found rarely in infants with other disorders (specificity 88.6% and 75.0%). CONCLUSIONS: Severe muscle weakness and contractures are the most reliable indicators of a neuromuscular disorder and should be carefully assessed in an infant with neonatal hypotonia.     

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.     

Wernicke-like encephalopathy after autologous bone marrow transplantation

A 15-year-old boy with non-T ALL in early 2nd remission was autografted using a regimen with busulphan 4 mg/kg/day, po, from day -9 to -6, and cyclophosphamide 50 mg/kg/day, iv, from day -5 to -2. During busulphan administration he experienced a few generalized seizures, and starting on day 25 post ABMT he developed a progressively severe neurological symptomatology characterized by nystagmus, right VIth cranial nerve palsy, truncal ataxia and, finally, confusion and coma. MRI showed lesions in the periaqueductal gray matter, thalamus, mammillary bodies and putamen. Within 24 hours of treatment with thiamine he improved dramatically, but during the following weeks permanent neurologic damage with memory deficit, truncal ataxia and nystagmus became evident. To our knowledge this is the first case of Wernicke's encephalopathy reported after BMT. We suspect in this case a contribution of busulphan to the development of the syndrome.
