Integrative multidisciplinary approaches by the Integrative Medicine Research Group (IMRG): a new frontier in cancer setting.

This conference addresses the topic of integrative, multidisciplinary approaches to cancer settings according to evidence-based medicine. The multidisciplinary approach of the researchers involved characterizes this new and complex scenario. The Integrative Medicine Research Group (IMRG) has always been committed to the activities and dissemination of CAM in cancer patients, focusing on the safety and efficacy of these approaches. Thus, one of the main goals of IMRG is to demonstrate that CAM can support cancer patients during treatment and improve their quality of life and survival. In addition, IMRG's multidisciplinary network is ever vigilant in assessing the risks of interactions between cancer drugs and nutraceuticals. We hope that the integrative medicine approach can be transferred to the level of all chronic diseases, including oncology.

Adapted physical activity for breast cancer patients: shared considerations with two Olympic and world Italian sports champions.

Breast cancer is a growing global public health concern. Thanks to the recent treatments progress, the survival rate of BC patients has significantly improved (88% of 5-year survival rate) and the number of cancer survivors has also increased. Notwithstanding these brilliant results, many BC patients have long-term side effects as pain, oedema, limited mobility, cancer related fatigue, etc. as a consequence of surgical, radiotherapy and medical treatments. For example, posture appears to be frequently altered after mastectomy, due to the impairment of the mobility of the arm caused by surgical scars. All these aspects negatively affect the health-related Quality of Life (QoL) of BC patients. Recent several randomized clinical trials have shown benefits of regular and appropriate physical activity (PA) during and after BC treatment, particularly in terms of benefits for health, reducing fatigue, improving strength levels, QoL and physical function. In this context, two types of sports have demonstrated their affinity and efficacy as treatment support during and after treatments for BC patients: fencing and rowing. Here we report considerations shared with two sport champions: the fencing Olympic gold medal Daniele Garozzo and the rowing World Champion Giovanni Ficarra, with the aim to find the adapted PA for BC patients.

Women in Neurosurgery: Historical Path to Self-Segregation and Proposal for an Integrated Future.

Despite the rising percentage of women accessing the medical profession over the last few decades, surgical specialties are still largely male-dominated; in particular, a remarkable gender disparity is evident in neurosurgery, where only 19% of practitioners are females. Although women may be reluctant to choose a challenging specialty like neurosurgery due to concerns around how to balance family and career, it must be admitted that prejudices against female neurosurgeons have been deeply rooted for long, prompting many to give up and switch track to less demanding subspecialties. Among those who have persisted, many, if not most, have experienced difficulties in career progression and received unequal treatment in comparison with their male counterparts. In 1989, a group of 8 female neurosurgeons founded Women in Neurosurgery (WINS), an organization that aimed to guarantee inclusivity in neurosurgery, encouraging a better and more egalitarian working environment. Thereafter, WINS sessions were regularly promoted at international conferences, offering female neurosurgeons a platform to report issues related to gender discrimination. Over recent years, the mission of WINS sessions in national and international conferences has taken an unexpected deviation; they have progressively become supplementary scientific sessions with only women neurosurgeons as speakers, thus paving the road to a form of self-segregation. This tendency has also resulted in the establishment of sections of only female neurosurgeons within some national societies. Although there remains a faction that fiercely supports the WINS mindset of reserved spaces for women, such segregation is an upsetting prospect for those who believe that science and professionalism have no gender; a growing part of the global neurosurgical community believes that the conception of a "female neurosurgery" and a "male neurosurgery" is misguided and counterproductive and consider the existence of the WINS as anachronistic and no longer necessary.

The medial cord to musculocutaneous (MCMc) nerve transfer: a new method to reanimate elbow flexion after C5-C6-C7-(C8) avulsive injuries of the brachial plexus--technique and results.

The aim of this paper is to report on our ample experience with the medial cord to musculocutaneous (MCMc) nerve transfer. The MCMc technique is a new type of neurotization which is able to reanimate the elbow flexion in multilevel avulsive injuries of the brachial plexus provided that at least the T1 root is intact. A series of 180 consecutive patients, divided into four classes according to the quality of hand function, is available for a long-term follow-up after brachial plexus surgery. The patients enrolled for the study have in common a brachial plexus palsy showing multiple cervical root avulsive injuries at two (C5-C6), three (C5-C6-C7) and four (C5-C6-C7-C8) levels. The reinnervation of the musculocutaneous nerve is obtained via an end-to-end transfer from two donor fascicles located in the medial cord. The selected fascicles are those directed principally to the flexor carpi radialis, ulnaris and, to a lesser degree, the flexor digitorum profundus. Under normal anatomic conditions, they are located in the medial cord, and their site corresponds to the inverted V-shaped bifurcation between the internal contribution of the median nerve and the ulnar nerve. The technique has no failure and no complications when the hand shows a normal wrist and finger flexion and a normal intrinsic function. In case of suboptimal conditions of the hand, the technique has proved technically more challenging, but still with 67% satisfactory results. In the four-root avulsive injuries, however, this method shows its limitations and an alternative strategy should be preferred when possible. EMG analysis shows a reinnervation in both the biceps and the brachialis muscles, explaining the high quality of the observed results. Moreover, this technique theoretically offers the possibility of a "second attempt" at a more distal level in case of failure of the first surgery. This procedure is quick, safe, extremely effective and easily feasible by an experienced plexus surgeon. The ideal candidate is a patient harbouring a C5-C6 avulsive injury of the upper brachial plexus with a normally functioning hand.

Bone Dysplasia as a Key Feature in Three Patients with a Novel Congenital Disorder of Glycosylation (CDG) Type II Due to a Deep Intronic Splice Mutation in TMEM165.

Three patients belonging to two families presented with a psychomotor-dysmorphism syndrome including postnatal growth deficiency and major spondylo-, epi-, and metaphyseal skeletal involvement. Other features were muscular hypotrophy, fat excess, partial growth hormone deficiency, and, in two of the three patients, episodes of unexplained fever. Additional investigations showed mild to moderate increases of serum transaminases (particularly of aspartate transaminase (AST)), creatine kinase (CK), and lactate dehydrogenase (LDH), as well as decreased coagulation factors VIII, IX, XI, and protein C. Diagnostic work-up revealed a type 2 serum transferrin isoelectrofocusing (IEF) pattern and a cathodal shift on apolipoprotein C-III IEF pointing to a combined N- and O-glycosylation defect. Known glycosylation disorders with similar N-glycan structures lacking galactose and sialic acid were excluded. Through a combination of homozygosity mapping and expression profiling, a deep intronic homozygous mutation (c.792 + 182G>A) was found in TMEM165 (TPARL) in the three patients. TMEM165 is a gene of unknown function, possibly involved in Golgi proton/calcium transport. Here we present a detailed clinical description of the three patients with this mutation. The TMEM165 deficiency represents a novel type of CDG (TMEM165-CDG). This disorder enlarges the group of CDG caused by deficiencies in proteins that are not specifically involved in glycosylation but that have functions in the organization and homeostasis of the intracellular compartments and the secretory pathway, like COG-CDG and ATP6V0A2-CDG.

Transarticular repair of the brachial plexus. Case report.

This paper illustrates the repair of a complex and unusually placed iatrogenic injury of the brachial plexus. The authors present the case of a 36-year old woman, musician (piano solista), with a dumbbell tumour of the brachial plexus. A general surgeon performed a gross total removal of the tumour, cutting it flush with the exit of the neuroforamen and this resulted in a severe upper brachial plexus injury. Four months later, the brachial plexus was repaired with a nerve graft, using a double extraforaminal and preforaminal approach via the transarticular route. The surgical procedure proved to be effective and without significant consequences for the patient.

Surgical treatment of common peroneal nerve injuries: indications and results. A series of 62 cases.

AIM: Common peroneal nerve (CPN) injuries represent the most common nerve lesions of the lower limb and can be due to several causative mechanisms. Although in most cases they recover spontaneously, an irreversible damage of the nerve is also likely to occur. Nerve regeneration following CPN repair is poorer if compared to other peripheral nerves and this can explain the reluctant attitude of many physicians towards the surgical treatment of these patients. Among the several factors advocated to explain the poor outcome following surgery, it has been suggested that reinnervation might be obstacled by the force imbalance between the functioning flexors and the paralysed extensors that eventually results in the fixed equinism of the foot, due to the excessive contracture of the active muscles and the shortening of the heel cord. Therefore the early correction of these forces might favour nerve regeneration. Following such hypothesis, the authors treat irreversible CPN injuries performing a one-stage procedure of nerve repair and tibialis tendon transfer. We report our experience, describing the indications to surgical treatment, the operative technique and the postoperative clinical outcome correlated with the causative mechanisms of the injuries. METHODS: A 62-patient series controlled over a period of 15 years with a post-traumatic palsy of the CPN is reported. All the patients underwent surgery. In open wounds, when a nerve transection was suspected, surgery was performed at emergency (2 cases). In closed injuries, operative treatment was advised when no spontaneous regeneration occurred 3-4 months after the injury. From 1988 till 1991, 9 patients were elected for surgery : in 6 cases treatment consisted of neuroma resection and nerve repair by means of a graft. In 3 patients it was performed only a CPN decompression at the fibular neck. Since 1991, surgical treatment has always consisted of nerve repair associated with a tendon transfer during the same procedure. Fifty-three patients were elected for surgery. Nerve repair was achieved by direct suture in 1 case and by means of a graft in 46 patients. Decompression of the CPN at the fibular neck was performed in 6 patients where nerve continuity was demonstrated. RESULTS: In the first group of patients, nerve repair outcome was highly disapponting: no recovery in 5 cases, reinnervation occurred in 1 patient only (M1-2). CPN decompression was followed by complete recovery in 2 cases, no improvement was observed in 1 case. Nerve repair associated with tibialis tendon transfer dramatically improved the postoperative outcome: at 2 year follow-up, neural regeneration was demonstrated in 90% of the patients. Surgical outcome depends on the causative mechanisms of the lesion: sharp injuries and severe dislocations of the knee had an excellent recovery, while in crush injuries and gunshot wounds good recovery was less common. CONCLUSION: Surgical treatment of CPN injuries can nowadays be highly rewarding. CPN palsies in open wounds should undergo surgical exploration at emergency. In close injuries with no spontaneous recovery within 4 months after the injury, patients should be advised to seek surgical treatment regardless the causative mechanism of the lesion. According to our experience, the association of a transfer procedure to nerve repair enhances neural regeneration, dramatically improving the surgical outcome of these injuries.

Common peroneal nerve injuries in knee dislocations: results with one-stage nerve repair and tibialis posterior tendon transfer.

We report our experience in the treatment of common peroneal nerve (CPN) palsy following knee dislocations: a twelve-year surgical series of 26 patients presenting with a traumatic injury of the lateral sciatic nerve and no spontaneous recovery is reviewed. From 1988 to 1991, we performed nerve surgery alone on 3 patients. Their results were highly disappointing and in none did we observe muscle recovery. Since 1991 nerve surgery was associated with a palliative procedure for 23 patients. Although at surgical exploration, severe nerve damage was found in 87% of these patients (thereby indicating the need for graft repair), the overall outcome was good, with a score of M3 on the BMRC scale in about 75% of the cases. These results suggest that the one-stage association of microsurgical nerve repair and tibialis posterior tendon transfer changed the destiny of these injuries.

Matrix-assisted laser desorption/ionization mass spectrometric peptide mapping of high molecular weight glutenin subunits 1Bx7 and 1Dy10 in Cheyenne cultivar.

This study describes the verification of the cDNA-deduced amino acid sequences of high molecular weight glutenin subunits 1Dy10 and 1Bx7 in Cheyenne cultivar by direct matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) analysis of their tryptic fragments omitting chromatographic pre-separation. These polypeptides have a conserved structure consisting of a long central repetitive domain that prevents the application of conventional sequencing procedures such as Edman degradation. The published sequence of subunit 1Dy10 contains 7 Lys and 13 Arg residues; thus the production of 21 tryptic peptides is expected. The cDNA-deduced sequence for 1Bx7 subunit includes 5 Lys and 15 Arg residues, but the presence of three Arg-Pro bonds, which are normally not cleaved by trypsin, predicts only 19 tryptic peptides. Three different matrices (DHB, SA and HCCA) in combination with the most compatible sample preparation procedures were used in order to obtain the maximum 1Dy10 and 1Bx7 sequence coverage. MALDI analysis of the 1Dy10 tryptic digest resulted in the identification of all 21 expected peptides. In the case of 1Bx7 MALDI analysis resulted in the identification of 17 of the 19 expected peptides, giving a sequence coverage of 99.3%. These results were sufficient to rule out glycosylation of the 1Dy10 and 1Bx7 proteins and to assess the absence of any other post-translational modification, to within the detection limits of the method.

Aggressive fibromatosis (desmoid tumor) of the radial nerve: favorable resolution. Case report.

Aggressive fibromatosis (desmoid tumor) of a peripheral nerve is a rarity. Isolated cases have been reported in which the tumor originated from neighboring structures and only secondarily invaded the nerves. The case described in this report is unusual because the tumor selectively invaded the patient's nerve fascicles, requiring removal and graft repair. The procedure was followed by an excellent clinical recovery and no recurrence as of the 6-year follow-up review.

Brachial plexus injuries. Guidelines for management: our experience.

In spite of the progress made by microneurosurgery, the treatment of brachial plexus injuries still remains a great challenge. This personal series of 49 patients with brachial plexus injuries (excluding tumours and thoracic outlet syndromes) is peculiar because the cases arose after the introduction in Italy of the law requiring all motorcyclists to wear a safety helmet. Our experience confirms that there has been a 32% increase in very severe almost irreparable injuries of the plexus in comparison with previous data reported in the literature. This is probably due to the higher rate of survival among severely-injured patients, although the possibility of a direct effect of the helmet on the plexus cannot be completely discarded. Our results confirm the good prognosis of the microsurgical repair of C5-C6 stretch injuries and infraclavicular lesions.
