RESUMEN
BACKGROUND: In breast surgery, an autologous flap combined with implant may reduce the risk or repair the soft-tissue defects in several cases. Traditionally, the preferred flap is the myocutaneous latissimus dorsi (LD) flap. In the perforator flap era, the evolution of LD flap is the thoracodorsal artery perforator (TDAP) flap. The aim of this study is the comparison between LD flap and TDAP flap with implants in terms of early complications and shoulder function. METHODS: We performed a retrospective cohort study in accordance with the STROBE guidelines. Between January 1 2015 and January 1 2020, 27 women underwent a unilateral total breast reconstruction with LD or TDAP flap combined with an implant at our institution. 15 women were operated with LD flap and 12 with TDAP flap. The most frequent indications for intervention were results of mastectomy and radiation-induced contracture. We evaluated several data in terms of clinical and demographical characteristics, operative and perioperative factors, and follow-up variables. We assessed shoulder function through the Disability of the Arm, Shoulder and Hand Questionnaire (DASH). RESULTS: The rate of complications was significantly lower in the TDAP group compared with the LD group (16.7% vs 60.0%, p = 0.047. Table 3). Although the small sample size limited further detailed statistical analyses, we particularly noticed no cases of donor site seroma in the TDAP group, as compared with four in the LD group. Patients in the TDAP group had an â¼11-point lower mean DASH score compared with the LD group (9.8 vs 20.5). This difference was statistically significant (p = 0.049). CONCLUSIONS: TDAP flap seems to be a reliable technique for soft-tissue coverage in total breast reconstruction with implants. In comparison with the traditional LD flap, it could be a more favorable option in terms of less complications and better quality of life.

BACKGROUND: Effective indicators of the early graft failure after pediatric liver transplantation are currently a crucial question. The aim of this study was to analyze retrospectively laboratory parameters that may help anticipate an early graft loss (GL). METHODS: The 131 pediatric liver transplantations, performed in our hospital from January 2002 to December 2005, were reviewed. Post-operative laboratory parameters, collected in the first 36 h of the Paediatric Intensive Care Unit (PICU) stay, were analyzed for children with both graft survival and GL. Receiver operating characteristics analysis was used to identify the optimal cut-off for the laboratory parameters. Multivariate logistic regression analysis was used to calculate the adjusted risk of GL for the prognostic parameters identified. RESULTS: The mean age at transplant was 1.1 years. The two groups were comparable for all recipient and donor variables considered. Children with GL showed significantly higher levels of ammonia and transaminase at the admission to the PICU and higher levels of prothrombin time, creatinine, lactate and a lower level of platelets at the 36 h of PICU. The laboratory parameters over the cut-off value by the multivariate logistic regression identified all early thromboses earlier than Doppler ultrasound. CONCLUSIONS: This study suggests that routine blood tests may help to anticipate an early loss of liver grafts in children after transplantation and may improve our diagnostic investigation in the case of thrombosis suspicion. Further validation by a prospective study is needed to carefully assess the sensitivity and specificity of the identified criteria.

Liver transplantation (OLT) remains a major medical and surgical challenge in small patients. From October 1997 through July 2004, 17 babies less than 6 kg underwent 18 OLTs. Median age and weight were 3 months (range = 1 to 9) and 4.7 kg (range = 2.2 to 5.8). Two whole, one reduced, and 15 split-liver grafts (left lateral segments) were obtained from donors of median age and weight of 11.6 years (range = 0.5 to 62) and 50 kg (range = 7 to 63). Donor-to-recipient median weight ratio (D/R) was 9.1 kg (range = 1.3 to 17.6) and median graft-to-recipient weight ratio (GRWR) was 5% (range = 3.1 to 10). The incidence of biliary complications was 23%. The only vascular complication was a portal vein thrombosis (6%). Fourteen patients (79%) are alive with good graft function at a median follow-up of 39 months (range = 0.5 to 74). Three patients (all status 1) died on postoperative day 285 (brain death), 17 (multiorgan failure), and 229 (cardiovascular failure during retransplantation). Actuarial patient survivals at 6 months and 6 years are 94% and 78% while graft survivals are 89% and 74%, respectively. Currently all the patients listed as UNOS status 2 and 3 (73%) at the time of transplant are alive. During the same period one premature neonate (1.8 kg) who presented with fulminant hepatic failure died on the waiting list after 12 days. Our data confirm that the extensive use of a split-liver technique from small adult or pediatric cadaveric donors can offer the benefits of liver transplantation to small pediatric candidates with excellent results.

OBJECTIVE: To investigate the kinetics of body nitrogen (N) excretion during 24 h glucose infusion (relating glycemia with insulin supply) and during subsequent 24 h saline infusion in injured patients during a full blown stress reaction. To define the lag time between the start of the withdrawal of glucose and insulin infusion, and the modification in the N loss from the body, and the time span to reach the maximum effect and its size. The knowledge of these variables is mandatory to plan short term studies in critically ill patients, while assuring the stability of the metabolic condition during the study period, and also to assess the possible weaning of the effect on protein breakdown during prolonged glucose and insulin infusion. DESIGN: 24-36 h after injury, patients were fasted ( < 100 g glucose) for 24 h (basal day). Thereafter, a 24 h glucose infusion in amount corresponding to measured fasting energy production rate (EPR), clamping glycemia at normal level with insulin supply followed by 24 h saline infusion, was performed. Total N, urea and 3-methyl-histidine (3-MH) in urine were measures on 4 h samples starting from 20th h of the basal day. SETTING: Multipurpose ICU in University Hospital. PATIENTS: 6 consecutive patients who underwent accidental and/or surgical injury, immediately admitted for respiratory assistance (FIO2 < 0.04). Excluded patients were those with abnormal nutritional status, cardiovascular compromise and organ failures. MAIN RESULTS: Patients showed a 33% increase in measured versus predicted fasting EPR and a consistent increase in N and 3-MH urinary loss. An infusion of glucose at 5.95 +/- 0.53 mg/kg x min (97.20 +/- 0.03% of the fasting measured EPR) with 1.22 +/- 0.18 mU/kg x min insulin infusion reduced N and 3-MH loss after a time lag of 12 h. The peak decrease in body N (-36%) and 3-MH loss (-38%) was reached during the first 12 h of glucose withdrawal period. Thereafter, during the following 12 h, the effect completely vanished confirming that it is therapy-dependent and that the metabolic environment of the patients did not change during the three days study period. CONCLUSION: 24 h glucose withdrawal reduces N and 3-MH loss injured patients, the drug-like effect is maintained during the first 12 h of withdrawal and thereafter disappears. The study suggests that at least a 24 h study period is necessary when planning studies exploring energy-protein metabolism relationship in injured patients, and, again 24 h before changing protocol in a crossover study.

OBJECTIVE: We investigated the amino acid (AA) tolerance during Total Parenteral Nutrition (TPN) in adult patients undergone liver transplant (LTX). DESIGN: The treatment (Glucose and AA), induced on the 2nd postoperative day, was later maintained with 27 kcal/kg Ideal Body Weight (IBW) as glucose and 0.12 (12 patients: protocol #1), 0.18 (10 patients: protocol #2) and 0.25 g nitrogen (N)/kg IBW (13 patients: protocol #3) till end of the 6th postoperative day. The N intake was sequentially modified in protocol #2 and #3 to increase the supply of the amino acid (AA) that resulted in an infusion plasma level below the expected "normal" range (between 1 and 1.6 times the overnight fasting plasma level of volunteer). PATIENTS: 35 consecutive adult patients without diabetes and organ failures for the entire study period. MEASUREMENTS: Plasma AA profile was measured before LTX and at the last TPN day under continuous infusion. During #1 and #2 protocol, many AA resulted below or at the lower range of the norm while, during 0.25 gN/kg IBW infusion, the majority of the administered AA significantly increased with respect to reference values. Nevertheless, they remained in the "normal" plasma range indicating that they were supplied in an optimal amount (particularly the aromatic and sulphurated ones, potentially toxic if liver function is impaired, and the branched chain AA (BCAA) given at consistent dosage: 0.5 g/kg). Arginine resulted significantly increased (Arg: 1.9 times the reference) and cystine (Cys: 0.45), serine (Ser: 0.8) and taurine (Tau: 0.85) remained significantly lower than "normal" as well as the not administered citrulline (Cit: 0.58) and alfa amino butyric acid (Aba: 0.41). The AA (and calorie) load almost balanced the N losses during the 5th (0.411 +/- 0.038) and 6th study day (0.305 +/- 0.019 gN/kg). CONCLUSIONS: 0.25 gN/kg could be considered the minimum N load in the uncomplicated adult LTX recipients, for reassuring a balanced plasma AA pattern and body N turnover in the early postoperative phase.

PURPOSE: To evaluate the effect induced on gas exchange and on urea excretion by glucose and insulin infusion in injured patients. The magnitude and time necessary for the full development of the metabolic effect were investigated. METHODS: Six injured patients were investigated. During the first 24 hours, the fasting period, patients received 1 mg/kg*min of glucose; during the second 24 hours, the treatment period, infusion was increased to about the 95% of the energy production rate; during the last 8 hours, (stop period) the infusion rate was again set to 1 mg/kg*min. Gas exchange was determined in two consecutive 12-hour series, for 30 minutes every hour, either during a stabilized treatment or after its variation. Urea excretion was determinated on 4-hour samples. RESULTS: With respect to the fasting period, during the last 4 hours of the treatment period, the energy production rate did not vary; urea excretion (-25%) and oxygen consumption (-9%) decreased significantly. Carbon dioxide production (+16%), total respiratory quotient, and minute ventilation (+5%) increased significantly. Carbon dioxide production varied linearly with time (glucose infusion +1.74 mL/min*m2*h, P < .05; glucose withdrawal -1.89 mL/min*m2*h, P < .01). Minute ventilation decreased only during the withdrawal period by 65 mL/min*m2*h (P < .05). CONCLUSIONS: The infusion of glucose and insulin, in an amount slightly lower than the metabolic expenditure, leads to a consistently reduced amino acid catabolism and to a decreased oxygen consumption, without affecting energy requirements. Although it leads to an increase of carbon dioxide production, the measured change is so small and slow that it is not harmful unless there is severe respiratory insufficiency.

Mitoxantrone was administered at the dose of 14 mg/m2 i.v. every 3 weeks to 25 consecutive women with measurable progressive disease who relapsed after adjuvant CMF and endocrine therapy. The treatment plan consisted in the delivery of 6 cycles, unless disease progression or severe toxicity occurred. All patients were evaluable for drug response and toxicity. One patient achieved complete remission and 6 partial remission, for a total response rate of 28%. Objective tumor response was observed in all major sites of disease. The median time to achieve remission was 3 months. The median duration of response was 7 months (range, 5-39+), and the median survival for the entire group was 10 months (range, 3-39+). Results were influenced only by the duration of disease-free status from the end of adjuvant CMF chemotherapy. In fact, all tumor responses were documented in woman with free intervals exceeding 1 year (7 of 17 or 41%). Treatment was generally well tolerated, with 10 patients developing leukopenia at some time during treatment. Only 2 patients received less than 75% of the projected dose because of granulocytopenia. Complete alopecia occurred in only 2 cases. Three patients developed a fall greater than 15% in left ventricular ejection fraction, but no episode of congestive heart failure was observed. We conclude that mitoxantrone is an effective and safe drug which can be utilized in women relapsing after adjuvant CMF.

The rate of margins involvement and the associated recurrence risk in basal cell carcinomas (BCCs) varies widely in published works (7%-25% and 26%-67%, respectively). This study investigated the risk factors associated with incomplete excision and their relevance in surgical management when positive margins occur in 3957 BCCs excised in 2358 patients. This study performed a multivariate analysis on the database collected from all patients operated for BCCs in the Plastic Surgery Department between 1 January 1992 and 1 September 2007. All data collected (3957 excisions; 2358 individuals) were divided into complete and incomplete excisions groups and analyzed according to 14 variables. The overall rate of incomplete excisions was 14%. Mean age (68), size of the lesion (< 0.5 cm), BCC subtype (nodular with sclerosant aspects, sclerosant and basosquamous), location (face), infiltration depth (hypodermis and deep tissues), recurrent BCC and re-excised BCC were significantly associated with a higher rate of incomplete excision. The recurrence rate for incompletely excised tumours was 26.8%, while only 5.9% for completely excised tumours. Most of the risk factors associated to incomplete excision can be identified before surgery (by simple anamnesis and clinical examination) and successfully overcome by appropriate surgical margins. The high recurrence rate after incomplete excision and the low patient compliance towards follow-up should lead the surgeon to early re-excise residual cancer.

CblD disorder is an autosomal recessive, rare, heterogeneous disease with variable clinical presentations, depending on the nature and location of the MMADHC gene mutations. Mutations in MMADHC lead to three distinct phenotypes: cblD-MMA, cblD-HC, and cblD-MMA/HC. To date, 18 cblD patients have been reported. Six of them were affected by cblD-MMA, but only three had a known clinical history. One of these patients presented with a metabolic decompensation at 11 months; the second one, born prematurely, was diagnosed with cblD after being treated for intracranial hemorrhage, respiratory distress syndrome, necrotizing enterocolitis, and convulsions at birth; the third one was diagnosed at 5 years of age.Here we present a case of a cblD-MMA patient who had an acute neonatal onset with severe hyperammonemia requiring hemodiafiltration. To the best of our knowledge, this is the first cblD-MMA patient who presented acutely in the newborn period. He has developed well upon treatment with B12, carnitine, and hypoproteic diet. At present time, at the age of 7, he shows normal growth and cognitive development. Thus, it is likely that the aggressive treatment of this child with hemodiafiltration might have prevented him from long-term neurological sequelae. Overall, this case shows that even severe, neonatal-onset patients may display a vitamin B12-responsive MMA. Furthermore, it suggests that an early treatment with vitamins might be beneficial for patients presenting with neonatal-onset hyperammonemia regardless of the suspected disease and before receiving the biochemical diagnosis.
RESUMEN
The preliminary experience of the first Italian program of pediatric intestinal transplantation is presented herein. A multidisciplinary group with broad experience in pediatric solid organ transplantation started the program. Nine children with complications of chronic intestinal failure were listed for transplantation. One child died on the waiting list; one received an isolated liver transplantation; three isolated intestinal; three multivisceral; and one, a combined liver/intestine transplantation. There was no in-hospital mortality, and all children were weaned from parenteral nutrition. The recipient of the multivisceral graft died after 14 months for unknown causes. All other recipients are alive after a median follow-up of 13 months. Patient and graft actuarial survivals for recipients of intestinal grafts were 100% at 1 year and 75% at 2 years.

INTRODUCTION: Use of extended criteria donors is one of the strategies to face the scarcity of donors for lung transplantation. METHODS: Between November 2002 and May 2009, we performed 52 LTs in 50 recipients, 10 of whom (group A) received lungs from donors aged 55 years or older (median, 58.5; range, 56-66 years) for comparison with 28 patients (group B) transplanted with lungs from donors younger than 55 years (median, 25.5; range, 15-54 years). We excluded 9 children and 3 recipients of combined liver plus lung transplantations from the study. RESULTS: Recipient age, gender, and indications for transplantation did not differ significantly between the 2 groups. Neither were there significant differences in PaO2/FiO2 ratios before lung retrieval, or length of the ischemic time The first PaO2/FiO2 on arrival to the intensive care unit (ICU) and the median length of ICU stay were similar. All patients, except 2 who died in the operating theatre, were extubated between 3 and 216 hours after the transplantation. Hospital mortality was similar in both groups: 3 patients in group A and 2 in group B (P = .1). The median portions of the predicted 1-second forced expiratory volume (FEV1) at 6 months after transplantation did not differ in the 2 groups: 62.4% in group A versus 70% in group B (P = .85). CONCLUSION: Lung grafts from donors older than 55 years can be effectively used for transplantation, thus increasing the total organ pool.

Sequential bilateral single lung-liver transplantation (SBSL-LTx) is a therapeutic option for patients with end stage lung and liver disease (ESLLD) due to cystic fibrosis (CF). A few cases have been reported, all of them were performed with the use of cardio-pulmonary by-pass (CPB). We performed SBSL-LTx in three young men affected by CF. All the recipients had respiratory failure and portal hypertension with hypersplenism. Along with lung transplants, two patients received a whole liver graft and one an extended right graft from an in situ split liver. During transplantation neither CPB nor veno-venous by-pass (VVB) were employed. Immunosuppression was based on basiliximab, tacrolimus, steroids and azathioprine. The three recipients are alive with a median follow-up of 670 days (range 244-1,533). Combined SBSL-LTx is a complex but effective procedure for the treatment of ESLLD due to CF, not necessarily requiring the use of CPB or VVB.

OBJECTIVE: To detect clinical signs and times of evaluation able to identify patients with good neurologic prognosis after out-of-hospital cardiac arrest. EXPERIMENTAL DESIGN: Retrospective study with 6 months-2 years of follow-up. SETTING: General intensive care unit, from 1993 to 1995. PATIENTS: Twenty-three patients aged 18-80 years, admitted with coma after out-of-hospital cardiac arrest, who survived at least 24 hours, without concomitant neurologic disorders. INTERVENTIONS: Neurologic outcome classification in three categories: complete neurologic recovery (A), moderate to severe disability (B), death without regained consciousness (C); A and B groups of patients are considered together as a "good neurologic outcome" group. MEASUREMENTS: Evaluation of some neurological parameters (GCS, motor response to pain, spontaneous motility, cranial nerve reflexes, spontaneous breathing, seizures) 6 hours (t0), 24 hours (t1), 72 hours (t2) and 7 days (t3) after arrest. RESULTS: Patients with good prognosis are identified with 100% sensitivity from the following parameters: at t0 none; at t1 motor response to pain, GCS > 4, absence of seizures; at t2 the former parameters, spontaneous breathing, brain stem reflexes, normal pupils; at t3 all the former parameters and spontaneous motility. Specificity is greater than 50% only for motor response to pain and GCS > 4. CONCLUSIONS: It is mostly impossible to state a neurologic prognosis in the first hours after cardiac arrest. The single predictor with the most reliable prognostic value is motor response to pain which allows, if present, to identify all the patients with a good prognosis as early as 24 hours after arrest.

In sixteen severely catabolic patients, two different nutritional treatments with the same nitrogen input (0.30 gN.kg-1.die-1) but with a different caloric support: 30 kcal.kg-1.die-1 foe group A and 15 kcal.kg-1.die-1 for group B were infused. Body nitrogen balance (BN), muscle nitrogen balance (BNm) and, calculated as a difference of the two, visceral nitrogen balance were measured in every patient on basal day and on the second day of total parenteral nutrition. Both nutritional treatment reduced the catabolic state in the same amount: this was confirmed by a less negative body BN and by the reduced excretion of 3-MEH and amino acidic catabolic markers. Otherwise in the other compartments the treatments showed different effects: the metabolic support was more reduced by treatment A than it was by B, supplying to visceral compartment a lower nitrogen amount: the nitrogen dismission from muscle compartment, available for visceral tissues, is greater with treatment B than with treatment A. In conclusion, even if both treatments show the same effect on body nitrogen balance, they penalize either one of the examined compartment or the other. To avoid this problem, the study and the use of tissue-specific nutrients are desiderable. Tissue-specific solutions may warrant the balance among body compartment without any further increase of the nitrogen rate.
