RESUMO
BACKGROUND: Antenatal substance use is a significant public health concern in South Africa (SA). Information on smoking, drinking and drug use during pregnancy was collected prospectively for the Safe Passage Study of the PASS (Prenatal Alcohol in Sudden infant death syndrome and Stillbirth) Network. OBJECTIVES: Data from 4 926 pregnant women in a community near Tygerberg Academic Hospital, Cape Town, were examined to determine whether associations between different substance use groups and postnatal infant outcomes at birth and 1 year were significant. METHODS: Gestational age (GA) was determined by earliest ultrasound. Maternal data were collected at enrolment or first antenatal visit. Substance use data were obtained at up to four occasions. Birthweight data were derived from medical records, and birthweight z-scores (BWZs) were specifically calculated using INTERGROWTH-21st study data. Statistical analyses were done with Statistica version 13. Results. Women who used more substances enrolled later, were younger, and had smaller mid-upper arm circumferences (MUACs), less education and lower monthly income than women who used no substances (control group). Infants born to women who used more substances had lower GA at delivery, birthweight and BWZ than infants from the control group. At 1 year, infants born to women who used more substances had a lower weight, shorter length and smaller head circumference. Education was positively associated with all infant outcomes at birth and 1 year. MUAC was positively associated with infant BWZ, and weight and length at 1 year. Income was negatively associated with BWZ, but positively associated with all 1-year outcomes. CONCLUSION: Substance use during pregnancy affects infant outcomes at birth and 1 year of age. The addictive properties of substance use make cessation difficult, so prevention strategies should be implemented long before pregnancy. Higher maternal education, associated with better infant outcomes at birth and 1 year and acting as a countermeasure to substance use, is of paramount importance.

Coronavirus disease-2019 (COVID-19) has caused an unprecedented demand on healthcare resources globally. In the light of the arrival of a novel contagious and life-threatening virus, the NHS has responded by making difficult decisions to maintain care for patients and protect staff. The response has been frequently amended following updates in the UK Government policy as scientific understanding of the virus has improved. Our Plastic Surgery practice has adapted to mitigate risk to patients by reducing face-to-face contact, downgrading emergency procedures and deferring elective surgery where possible. This has inevitably resulted in a backlog in elective surgery and outpatient appointments. An assessment of the long-term health, social and economic impact of NHS wide service reconfiguration upon patient outcomes is yet to be seen. In this paper, we review the demonstrable early effects of service changes upon our unit and compare those to national and internationally published data. We also outline some of the considerations being made as we consider strategies to resume services in the light of the ongoing COVID-19 pandemic.

BACKGROUND: Although women are informed about the dangers of drinking and smoking during pregnancy when they book for antenatal care, it is uncertain whether this advice is accepted, or whether attempts are made to apply it in subsequent pregnancies. OBJECTIVES: To assess how pregnant women respond to the advice to refrain from smoking and drinking during pregnancy in subsequent pregnancies. METHODS: Research staff were trained to obtain accurate prospective information on smoking and drinking during pregnancy in a prospective study, using well-standardised methods. Care was taken to inform participants about the dangers of smoking and drinking during pregnancy. They were also given pamphlets on these dangers in their own language and a list of telephone numbers where they could find help to quit should they need it. This information was repeated at subsequent study visits (ranging from 1 to 3, depending on the gestational age at which they enrolled). Gestational age was determined by early ultrasound. Z-scores of birthweight for gestational age were determined according to the INTERGROWTH-21st study. Pregnancy outcomes of women who enrolled twice (n=888) or three times (n=77) in the Safe Passage Study were compared with those of women in the first enrolment (n=889). RESULTS: The proportion of drinkers did not change significantly (p=0.058) from the first to the second and third enrolments (63.8%, 59.0% and 54.6%, respectively). A similar trend was found for smokers (73.3%, 72.2% and 68.4%, respectively). Cannabis use was reported by 15.1%, 9.7% and 12.0% (p<0.005) of women, respectively, and use of methamphetamine by 10.1%, 6.6% and 12.7% (p<0.005). There was an increase in the rate of preterm births from 15.5% to 17.5% and 24.7%, respectively, but the increase was not significant. Although mean birthweight was lower in the third enrolment compared with the second, the difference was not significant. The z-score of birthweight for gestational age was significantly lower in the second enrolment compared with the first. CONCLUSIONS: Detailed information on the adverse effects of smoking and drinking during pregnancy was not effective in the population studied. Other methods to reduce or stop these toxic exposures should therefore be investigated. A short inter-pregnancy interval, as demonstrated by three enrolments in 7.5 years, is associated with preterm labour and fetal growth restriction, and is probably indicative of the role played by confounders such as poor socioeconomic conditions and drug exposure during pregnancy.

Preliminary data suggest that allogeneic stem cell transplantation (allo-SCT) may be effective in T-prolymphocytic leukemia (T-PLL). The purpose of the present observational study was to assess the outcome of allo-SCT in patients aged 65 years or younger with a centrally confirmed diagnosis of T-PLL. Patients were consecutively registered with the EBMT at the time of transplantation and followed by routine EBMT monitoring but with an extended dataset. Between 2007 and 2012, 37 evaluable patients (median age 56 years) were accrued. Pre-treatment contained alemtuzumab in 95% of patients. Sixty-two percent were in complete remission (CR) at the time of allo-SCT. Conditioning contained total body irradiation with 6 Gy or more (TBI6) in 30% of patients. With a median follow-up of 50 months, the 4-year non-relapse mortality, relapse incidence, progression-free (PFS) and overall survival were 32, 38, 30 and 42%, respectively. By univariate analysis, TBI6 in the conditioning was the only significant predictor for a low relapse risk, and an interval between diagnosis and allo-SCT of more than 12 months was associated with a lower NRM. This study confirms for the first time prospectively that allo-SCT can provide long-term disease control in a sizable albeit limited proportion of patients with T-PLL.

AIM: Ventral rectopexy (VR) has gained popularity in the management of obstructive defaecation syndrome (ODS) due to a symptomatic rectocele ± intussusception. Data on the efficacy and safety of VR are variable and there are few predictors of successful outcome. This study aimed to examine whether or not an adverse obstetric history influenced the functional outcome following VR for ODS. METHOD: This was a retrospective study of a cohort of 76 consecutive patients who had undergone VR for ODS at a tertiary referral centre between 2012 and 2015. Patients were followed up by telephone questionnaire. The obstetric history and pre- and postoperative symptoms of ODS and faecal incontinence (FI) were obtained from telephone interviews. RESULTS: In this cohort, symptoms of ODS were significantly improved by surgery, with 56% of patients showing a reduction of symptoms of 50% or more (P < 0.001). Subgroup analysis demonstrated that a lower body mass index (BMI; 24.4 vs 27.3 kg/m2 ; P < 0.05) and shorter duration of symptoms (7 vs 10 years; P < 0.05) led to a better outcome. VR had no effect on FI. Obstetric factors such as foetal weight, instrumental delivery, episiotomy, perineal tear and total number of deliveries did not influence outcomes. CONCLUSION: Patients with a less straightforward obstetric history can be reassured that this should not adversely influence the functional outcome after VR for ODS. Colorectal surgeons who offer this surgery should warn patients with an elevated BMI or with longstanding symptoms that the operation may be less successful than for those with a lower BMI or shorter duration of symptoms.

BACKGROUND: A 5-year follow-up study of 633 cutaneous squamous cell cancer (SCC) excisions was performed by collecting data on rates of local recurrence (LR) and lymph node (LN) metastasis. METHODS: A retrospective analysis of patients was performed across four regional plastic surgery centres (Stoke Mandeville Hospital, Aylesbury; John Radcliffe Hospital, Oxford; Salisbury District Hospital, Salisbury and Queen Alexandra Hospital, Portsmouth) assessing rates of LR and LN metastasis. RESULTS: We report 5-year outcomes from 598 SCCs (95% follow-up rate). The total recurrence rate (LR and LN metastasis) was 6.7% (n = 40) at 5 years, with 96% of these occurring within 2 years. Median time to LR was 9 months (1-57), with 76.9% (n = 20) undergoing further wide local excision. Median time to LN metastasis was 5.5 months (1-18 months). There were two cases of disease-related death. Only 15% (n = 6) of incomplete excisions recurred. Interestingly, 19.1% (n = 9) of 47 SCCs with perineural invasion on original histopathology recurred versus only 5.6% (n = 31) of the 551 SCCs without perineural invasion (p = 0.005). CONCLUSIONS: This study is one of the largest studies to date following up 598 SCC excisions at 5 years with total recurrence rates comparable to those in current published literature. We report perineural invasion as a significant predictor of recurrence and that 96% of total recurrence occurred within 2 years. This is in contrast to current UK guidelines (75% at 2 years, 95% at 5 years), thus suggesting that shorter length of hospital follow-up may be reasonable.

We report outcomes for 44 children who underwent stem cell transplantation (SCT) for refractory AML in the UK between 2000 and 2012. Median age at SCT was 11.5 years. Twenty-three patients had primary refractory and 21 relapsed refractory AML. Refractory disease was confirmed by cytogenetics/molecular genetics in 24 cases. Median follow-up of the whole cohort is 6.8 years (2.1-14.9 years). Thirty patients (68%) achieved a CR following SCT. Transplant-related mortality at 1 year was 18%. Acute GVHD incidence was 52% (grade ⩾III 19%), chronic 7%. Relapse was the major cause of treatment failure and occurred in 32% of patients at a median of 61 days post SCT. Five-year overall survival and leukemia-free survival (LFS) were 43% (95% CI 31-61%). All patients with favorable cytogenetics (n=6) are alive in CR. Outcomes in patients with primary refractory disease were equivalent to those with relapsed refractory AML. Blast percentage ⩽30% in the BM pre-SCT, myeloablative conditioning and acute GVHD proved to be favorable prognostic features. We could stratify patients according to age ⩾10 years and >30% blasts in BM pre-SCT. Patients with none/one of these risk factors were highly salvageable (5 years LFS 53%) whereas those with both factors had a very poor prognosis (5 years LFS 10%). This may facilitate decision making on whether it is appropriate to consider transplant in such patients.

Improving haematopoietic cell transplantation outcomes by selection of an HLA-matched unrelated donor is best practice; however, donor selection by secondary characteristics is controversial. We studied 1271 recipients with haematological malignancies who underwent T-cell-depleted allografts and had complete data on HLA-matching status for six loci (HLA-A, -B, -C, -DRB1, -DQB1, -DPB1) and clinical outcome data. Five-year overall survival was 40.6%. HLA mismatching (at HLA-A, -B, -C, -DRB1, -DQB1) relative risk (RR) 1.22, 95% confidence interval (CI) 1.2-1.5, P=0.033 for 1 mismatch and RR 1.46, 95% CI 1.1-1.9, P=0.009 for >1 mismatch) and CMV mismatching (RR 1.37, 95% CI 1.2-1.6, P<0.001) were significantly associated with inferior survival. Donors aged <30 years showed a trend towards better survival. The multivariate model for mortality, combining CMV and HLA-match status, found an RR of 1.36 (95% CI 1.1-1.7, P=0.003) for HLA matched/CMV mismatched, an RR of 1.22 (95% CI 0.99-1.5, P=0.062) for HLA mismatched/CMV matched and an RR of 1.81 (95% CI 1.4-2.3, P=<0.001) for HLA/ CMV mismatched, compared with the HLA/CMV-matched recipients. These data suggest that HLA and CMV matching status should be considered when selecting unrelated donors and that CMV matching may abrogate the effect of an HLA mismatch.

Even with the availability of targeted drugs, allogeneic hematopoietic cell transplantation (allo-HCT) is the only therapy with curative potential for patients with CLL. Cure can be assessed by comparing long-term survival of patients to the matched general population. Using data from 2589 patients who received allo-HCT between 2000 and 2010, we used landmark analyses and methods from relative survival analysis to calculate excess mortality compared with an age-, sex- and calendar year-matched general population. Estimated event-free survival, overall survival and non-relapse mortality (NRM) 10 years after allo-HCT were 28% (95% confidence interval (CI), 25-31), 35% (95% CI, 32-38) and 40% (95% CI, 37-42), respectively. Patients who passed the 5-year landmark event-free survival (N=394) had a 79% probability (95% CI, 73-85) of surviving the subsequent 5 years without an event. Relapse and NRM contributed equally to treatment failure. Five-year mortality for 45- and 65-year-old reference patients who were event-free at the 5-year landmark was 8% and 47% compared with 3% and 14% in the matched general population, respectively. The prospect of long-term disease-free survival remains an argument to consider allo-HCT for young patients with high-risk CLL, and programs to understand and prevent late causes of failure for long-term survivors are warranted, especially for older patients.

We describe a case of postoperative galactorrhea following the use of a pedicled pectoralis major myocutaneous flap for reconstruction of a pharyngolaryngeal defect in a woman with squamous cell carcinoma. We believe this to be unique in the literature, and an important complication to be reported, due to the similarities in appearance of galactorrhoea and postoperative aerodigestive tract/cutaneous fistula.

BACKGROUND: To evaluate long-term outcome of myeloablative allogeneic stem cell transplantation (allo-SCT) (MAC) versus reduced-intensity allo-SCT (RIC) in patients with relapsed/refractory Hodgkin's lymphoma (HL) in recent years. PATIENTS AND METHODS: A total of 312 patients (63 MAC and 249 RIC) with relapsed/refractory HL who received allo-SCT between 2006 and 2010 and were reported to the EBMT Database were included in the study. RESULTS: With a median follow-up for alive patients of 56 (26-73) months, there were no significant differences in non-relapse mortality (NRM) between MAC and RIC. Relapse rate (RR) was somewhat lower in the MAC group (41% versus 52% at 24 months, P = 0.16). This lower RR translated into a marginal improvement in event-free survival (EFS) for the MAC group (48% versus 36% at 24 months, P = 0.09) with no significant differences in overall survival (73% for MAC and 62% for RIC at 24 months, P = 0.13). Multivariate analysis after adjusting for disease status at the time of allo-SCT showed that the use of MAC was of borderline statistical significance for predicting a lower RR and EFS [HR 0.7, 95% CI (0.5-1.0), P = 0.1] and [HR 0.7, 95% CI (0.5-1.0), P = 0.07], respectively, after allo-SCT. CONCLUSIONS: With modern transplant practices, the NRM associated with MAC for HL has strongly decreased, resulting into non-significant improvement of EFS because of a somewhat better disease control compared with RIC transplants. The intensity of conditioning regimens should be considered when designing individual allo-SCT strategies or clinical trials in patients with relapsed/refractory HL.

We describe the use and outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for multiple myeloma (MM) in Europe between January 1990 and December 2012. We identified 7333 patients, median age at allo-HSCT was 51 years (range: 18-78), of whom 4539 (62%) were males. We distinguished three groups: (1) allo-HSCT upfront (n=1924), (2) tandem auto-allo-HSCT (n=2004) and (3) allo-HSCT as a second line treatment and beyond (n=3405). Overall, there is a steady increase in numbers of allo-HSCT over the years. Upfront allo-HSCT use increased up to year 2000, followed by a decrease thereafter and represented 12% of allo-HSCTs performed in 2012. Tandem auto-allo-HSCT peaked around year 2004 and contributed to 19% of allo-HSCTs in 2012. Allo-HSCT as salvage after one or two or three autografts was steadily increasing over the last years and represented 69% of allo-HSCTs in 2012. Remarkable heterogeneity in using allo-HSCT was observed among the different European countries. The 5-year survival probabilities from time of allo-HSCT for the three groups after year 2004 were 42%, 54% and 32%, respectively. These results show that the use of allo-HSCT is increasing in Europe, especially as second line treatment and beyond. There is an unmet need for well-designed prospective studies investigating allo-HSCT as salvage therapy for MM.

Loeys-Dietz syndrome is a rare form of connective tissue disorder, whose clinical features can resemble those of Marfan syndrome, but with a more unpolished appearance. Recently brought out, this pathology remains little known; however, its consequences may be dramatic. We report on the case of a 4-year-old girl followed for a congenital hip dislocation, in which a systematic exam found increased cutaneous elasticity and a bifid uvula, suggesting a connective tissue disorder. Symptoms were unpolished, as the child's height was normal, without any positive cardiac, rheumatological, or ophthalmological family history. Cardiovascular tests found a thoracic aortic aneurysm at the Valsalva sinus (26mm, Z-score=+4.24). A genetic investigation found a TGFßR2 gene mutation, leading to the diagnosis of Loeys-Dietz syndrome type 2. Skeletal damage associated with bifid uvula and/or hypertelorism and an aneurysm of the ascending aorta should guide the genetic investigation to the search for TGF-ß vasculopathy such as Loeys-Dietz syndrome.

Discrepancies exist between the care of unrelated donors (UDs) and related donors (RDs), particularly regarding medical suitability criteria, consenting procedures and donor follow-up. Changes to the most recent JACIE standards have addressed these issues. We studied 208 RDs who underwent PBSC or BM donation in a single centre during 2004-2013 to determine the impact of regulatory changes on donor care, and assessed the safety and efficacy of stem cell donation in donors not meeting UD medical suitability criteria. We observed significant improvements in donor consenting procedures (P=0.003) and donor follow-up (P=0.007) after stipulations in these areas were introduced. We saw a higher incidence of serious adverse events (SAEs) in RDs not meeting UD suitability criteria (P=0.018), and a higher incidence of SAEs in donors ⩾60 years (P=0.020). Haematopoietic progenitor cell donation is less safe in RDs who do not meet UD criteria for medical suitability. Although changes to JACIE standards have improved practice, development of specific medical suitability for RDs and guidelines around 'grey areas' where risks to a donor are unclear or theoretical, will be important in improving RD safety and standardising practice.

Ovarian cancer patients are typically treated with carboplatin and paclitaxel, but suffer a high rate of relapse with recalcitrant disease. This challenge has fostered the development of novel approaches to treatment, including antagonists of the 'inhibitor of apoptosis proteins' (IAPs), also called SMAC mimetics, as apoptosis-inducing agents whose action is opposed by caspase inhibitors. Surprisingly, IAP antagonist plus caspase inhibitor (IZ) treatment selectively induced a tumor necrosis factor-α (TNFα)-dependent death among several apoptosis-resistant cell lines and patient xenografts. The induction of necroptosis was common in ovarian cancer, with expression of catalytically active receptor-interacting protein kinase-3 (RIPK3) necessary for death, and in fact sufficient to compromise survival of RIPK3-negative, necroptosis-resistant ovarian cancer cells. The formation of a necrosome-like complex with a second critical effector, receptor-interacting serine-threonine kinase-1 (RIPK1), was observed. RIPK1, RIPK3 and TNFα were required for the induction of death, as agents that inhibit the function of any of these targets prevented cell death. Abundant RIPK3 transcript is common in serous ovarian cancers, suggesting that further evaluation and targeting of this RIPK3-dependent pathway may be of clinical benefit.

BACKGROUND: Although colorectal cancer (CRC) screening is widely recommended, screening rates remain low. Workplace interventions have the potential to increase rates of screening. AIMS: To evaluate the impact of a workplace CRC screening program targeting active duty and retired firefighters. METHODS: A letter, a fecal immunochemical test (FIT) kit and a survey were mailed to all active duty and retired San Francisco firefighters aged 40 and older during 2008-09. The survey included questions about CRC risk factors and prior CRC screening tests. The primary outcome was return of the completed FIT. RESULTS: FIT kits and surveys were sent to 1203 firefighters. In total, 445 individuals (37%) completed the survey, and 400 (33%) completed the FIT. Forty-five per cent of respondents had had a stool test for blood at some time, although few (8%) had had it within the past year. Thirty-six per cent of respondents said they had had a sigmoidoscopy at some time, although only 15% had had it within the past 5 years and 37% within the past 10 years. Among those aged 50 and older, 59% had had a test for colon cancer at some time. CONCLUSIONS: A workplace intervention can increase CRC screening rates in firefighters. Future studies should focus on the long-term sustainability of this type of program.

The presence of minimal residual disease (MRD) by multiparametric flow cytometry (MFC) has been associated with adverse outcomes in AML patients treated with chemotherapy alone, but its impact in the setting of allogeneic hematopoietic SCT (HSCT) is less clear. We studied 88 patients who underwent myeloablative (MA) or reduced-intensity conditioned allogeneic HSCT for AML in first or subsequent remission at our center. MRD status was determined using three-color MFC on pre-HSCT BM aspirates, and patients were stratified by MRD status into MRD-negative, low-level MRD-positive (<1%) or high-level MRD-positive groups (1-4.9%). Two-year survival estimates in these groups were 66.8%, 51% and 30%, respectively (P=0.012), and 2-year estimates of relapse were 7.6, 37 and 70% (P<0.001). Pre-HSCT MRD was related to disease characteristics including secondary AML (P=0.002) and primary induction failure (P=0.005), but, despite these strong correlations, MRD remained independently associated with poorer survival in multivariate analysis (hazard ratio, 1.92; P=0.014). Pre-HSCT MRD is associated with adverse clinical outcomes in AML patients undergoing reduced-intensity or MA HSCT in first or subsequent remission and should be integrated into transplant strategies for patients with AML.

Candida Osteomyelitis is uncommon.(1,2) It is associated with surgery, broad spectrum antibiotic use, central venous catheter insertion and immunosuppression.(2) We present a rare case of candidal rib osteomyelitis presenting initially with an innocuous skin lesion managed by extensive excision and reconstruction with minimal duration of post-operative antimicrobial therapy.
