A retrospective study of 400 consecutive case records was made to establish the clinical significance of the low lying placenta found on ultrasound. Diagnostic accuracy is discussed. 30% of the patients had a low lying placenta on early scan. Of these, 73% had a follow up scan. There was a progressive drop in the incidence of low lying placentae through pregancy until at term, in this study, there was no placenta previa. It is considered that a repeat scan is necessary to exclude placenta previa, but not until 34 weeks gestation. Amongst the patients with early low lying placentae the incidence of antepartum haemorrhage of indeterminate type was significantly high (P<0.001). A careful surveillance of these patients is therefore required. Dynamic placental migration may be the cause of this bleeding. Further study is necessary to determine the effect of early placental position on subsequent fetal development.

Objectives The aim of this multicentre retrospective study was to review the clinical data, outcomes and histopathological features of cats that had been treated for ocular surface dermoids. Methods Thirteen cats from various private practices in France with a clinical diagnosis of ocular surface dermoid were included in the study. Results The mean age of the study population at the time of diagnosis was 5 months. There were nine males and four females. Three different breeds were, including: domestic shorthair (n = 7), Birman (n = 4) and Havana Brown (n = 2). Two of the four Birmans were related (same sire). The two Havana Browns were also related (same sire). All of the dermoids were unilateral. Five of the dermoids were strictly conjunctival. Four affected both the conjunctiva and the cornea. Three affected both the conjunctiva and the eyelid, and one was strictly corneal. They were located in various positions: temporal (n = 9), inferonasal (n = 1), dorsonasal (n = 1) and dorsotemporal (n = 1). The last dermoid was heterogeneous and involved the nasal, dorsal and temporal quadrants. Concurrent eye diseases were observed in five patients: four cats exhibited associated eyelid agenesis and one cat exhibited persistent iris-to-iris pupillary membranes. Ten dermoids were surgically excised with no recurrences. Surgery was not performed for three cats: one cat died a few days after diagnosis and two cats were lost to follow-up after initial presentation. Conclusions and relevance Ocular surface dermoids are a rare condition in cats that can be treated successfully by surgical excision. Although our study reports only a small number of cases, the observation of ocular surface dermoids in two related cats in two different breeds indicates that genetic transmission is likely.

Abstract Background The mammillary bodies (MBs) have repeatedly been shown to be critical for memory, yet little is known about their involvement in numerous neurological conditions linked to memory impairments, including neonatal encephalopathy. Methods We implemented a multicentre retrospective study, assessing magnetic resonance scans of 219 infants with neonatal encephalopathy who had undergone hypothermia treatment in neonatal intensive care units located in the Netherlands and Italy. Results Abnormal MB signal was observed in ~40% of infants scanned; in half of these cases, the brain appeared otherwise normal. MB involvement was not related to the severity of encephalopathy or the pattern/severity of hypoxic–ischaemic brain injury. Follow-up scans were available for 18 cases with abnormal MB signal; in eight of these cases, the MBs appeared severely atrophic. Conclusions This study highlights the importance of assessing the status of the MBs in neonatal encephalopathy; this may require changes to scanning protocols to ensure that the slices are sufficiently thin to capture the MBs. Furthermore, long-term follow-up of infants with abnormal MB signal is needed to determine the effects on cognition, which may enable the use of early intervention strategies. Further research is needed to assess the role of therapeutic hypothermia in MB involvement in neonatal encephalopathy. Impact The MBs are particularly sensitive to hypoxia in neonates. Current hypothermia treatment provides incomplete protection against MB injury. MB involvement is likely overlooked as it can often occur when the rest of the brain appears normal. Given the importance of the MBs for memory, it is necessary that this region is properly assessed in neonatal encephalopathy. This may require improvements in scanning protocols.

Background: Shotgun injuries of the peripheral nerves are presented frequently during the last decades at the Service of Neurosurgery of UHC “Mother Theresa” in Tirana. In such cases the surgical repair of brachial plexus and peripheral nerves constitutes a challenge with relation to difficulties related with mechanism of injury, coexistence of other vascular damage, bone, soft tissue and visceral lesions. Materials and methods: A retrospective study of operated cases with shotgun injuries treated in our Department from 1997 to 2012 was conducted getting information from clinical charts, surgical registries, intraoperative photos and videos of the surgical repair of peripheral nerves. We performed a thorough analysis of the most influencing factors of surgical outcome such as: age, severity of injury, site of injury with relation to the innervated muscles, type of necessary nerve repair, presence of causalgia before operation, concomitant compromise of vascularization and/or locomotor apparatus. Follow-up of the patient was conducted through out-patient visits and phone interviews going back 10 years from surgical repair. Results: 68 cases operated for shotgun injury of brachial plexus or peripheral nerves were revised. There were different ages and both sexes involved. The type of nerve repair went from interfascicular neurolysis to direct end-to-end microsuture and nerve grafting. Timely repair of the nerve injury proved to be yielding better result than late repair in terms of pain relief and sensory motor improvement of the preoperative neurological deficit. The degree and the quality of improvement after surgery is related to the type of repair (neurolysis improves better and faster than grafting), the distance from site of injury to the effector muscle (the longer the distance more time it takes for the function to recover). The recovery of the brachial plexus was followed up for many years and further surgery proved to be necessary and of further improvement. Conclusions: From our long term experience dealing with surgical repair of shotgun injury of peripheral nerves we have learnt that early surgical repair is more efficacious in treating pain and gives better results in terms of motor and sensitive recovery than six months after injury as it was usually done. Long term follow-up is necessary to help with further surgery in case of distal decompressive surgery in anatomical tunnels.

In this retrospective study we report on two comparable groups of patients with advanced carpal arthritis treated with either proximal row carpectomy combined with a pyrocarbon resurfacing of the capitate (31 patients) or a four-corner arthrodesis and dorsal plating (26 patients). Follow-up time was 46 months (24–118). Except for a modestly higher radial wrist deviation in the patients treated with four-corner arthrodesis, there were no significant differences in outcomes between the groups. Asymptomatic progression of osteoarthritis in the lunate fossa was observed in four cases in both groups. Two cases were converted to a total wrist arthrodesis in the pyrocarbon group compared with one case in the four-corner arthrodesis group. Although four-corner arthrodesis remains the reference standard in the treatment of wrist osteoarthritis with involvement of the midcarpal joint, proximal row carpectomy combined with pyrocarbon resurfacing of the capitate is an alternative option. It can even be used in selected cases with erosion of the lunate fossa. Level of evidence: III
