Unpacking the 2-year age-gap provision in relation to the decriminalisation of underage consensual sex in South Africa

Over the past 24 years, the South African criminal justice system has undergone major transformations in relation to sexual offences,including sexual violence against children. More recently, there have been a number of developments to certain provisions in the law relating to sexual offences involving children. In response to the Teddy Bear Clinic Court Case and Constitutional Court ruling, sexual offences legislation related to underage consensual sex amended.In this regard, the legislation now decriminalises underage consensual sexual activity between adolescent peers aged 12 - 15-year-olds. In addition, the law provides broader definitions for consensual sexual activity including decriminalising consensual sex and sexual activity between older adolescents (above age of consent for sex, i.e. 16 - 17-year-olds)and younger adolescents (below the age of consent for sex, i.e. 12 - 15-year-olds), granted that there is no more than a 2-year age gap between them. One of the reasons for decriminalising consensual sexual activities between adolescent peers was because the expanded legislation cast the net for sexual offences so wide that the effects had far-reaching harmful impacts, particularly for girls, who would then be exposed to the criminal justice system. This paper focuses on unpacking the 2-year age-gap provision in SA legislation relative to selected better-resourced countries, including the rationale and the potential implications for adolescents (outside of the 2-year age gap provisions),for researchers, service providers and policy-makers. It concludes with recommendations for law reform and further research

Addressing legal and policy barriers to male circumcision for adolescent boys in South Africa.

With millions of adolescents becoming infected with HIV globally, it is essential that barriers to much-needed interventions are reduced for at-risk adolescents. In this article we review the legal and policy framework in South Africa for adolescent access to male circumcision. We are of the view that the framework does confer protection for adolescent boys while enabling access to male circumcision; however, we identify ambiguities and tensions that exist between the Children's Act, regulations and national guidelines. We recommend reform to further enable access by this vulnerable group to this prevention modality.

Boni mores and consent for child research in South Africa.

Consent is required for almost all health research. In order for consent to be valid a number of requirements must be met including that the consent cannot be contra bonos mores or contrary to public policy. This principle has its roots in the common law and it is used to ensure that the consent to harm, or the risk of harm, is permitted or ought to be permitted by the legal order. Recently, it has also become a statutory requirement embedded in the consent obligations relating to non-therapeutic health research with minors. Section 71 of the National Health Act provides that the Minister of Health (or potentially his or her delegated authority) must provide consent to non-therapeutic research with minors. However, such consent may not be granted if 'the reasons for the consent to the research or experimentation are contrary to public policy'. Limited work has been done on how to determine when consent to health research with children would be contrary to public policy. This article attempts to begin the debate by describing the boni mores principle, setting out some of the general factors that could be used to assess whether consent is consistent with it and suggesting how they could be applied to health research. The article concludes by stating that simply requiring proxy consent for non-therapeutic health research with children is insufficient as it cannot always be assumed that proxy consenters will act in the best interests of the child. Thus the boni mores principle acts as a limit on autonomy in order to protect the child participant. It is further submitted that establishing when consent to health research is consistent with public policy requires an assessment of whether the research is consistent with constitutional values, prevailing legal norms regarding children, and an assessment of the legal convictions of the community.

RANZCR 2006 peer review audit instrument.

The Royal Australian and New Zealand College Radiologists (RANZCR) continuing professional development programme incorporates audit with feedback as one important activity. The 2004 audit tool improves radiation oncologist practice quality; however, the instrument is designed to be regularly refined. To refine the 2004 audit tool and present the new instrument we incorporated comments and suggestions from: (i) the auditor and radiation oncologist from the single machine unit trial; (ii) members of RANZCR Post-Fellowship Education Committee; (iii) New South Wales Department of Health mandatory prescription requirements; and (iv) the International Atomic Energy Agency audit tool. In July 2006, the revised instrument was designed then endorsed by Post-Fellowship Education Committee. Important changes include: (i) combining criteria which separately scored documentation and correctness for similar items; (ii) scoring treatment schedule more explicitly; (iii) separating target volume coverage and critical structure dose; (iv) altering performance criteria scoring to be sensitive to peer review when no consensus can be reached; and (v) strengthening instructions for use and notes to improve comprehension and acceptance. The refined 2006 instrument should be more user-friendly while increasing its usefulness.

Amyloidosis of the breast mimicking recurrence in a previously treated early breast cancer.

Amyloid involvement of the breast is infrequently reported and may have clinical and radiological features suspicious for a primary breast malignancy. We describe a case of amyloid of the breast in which asymptomatic mammographic findings were suspicious for locally recurrent disease in a patient with previously treated breast cancer.

Possible involvement of sulfane sulfur in homocysteine-induced atherosclerosis.

Homocysteinemia, first identified as a genetic disease in children in the 1960s, is associated with severe widespread atherosclerosis which causes death (in untreated cases) before the age of 10 years. Elevated blood homocysteine is now recognized as a risk factor for heart disease in the general population. The mechanism by which homocysteine induces atherosclerosis is still unknown despite intensive investigation. It is proposed here that the mechanism involves sulfane sulfur formed in the catabolism of homocysteine. This unstable and reactive form of sulfur is formed through the action of several enzymes which are known to use homocysteine, its disulfide (homocystine), or its mixed disulfide with cysteine as substrates. Sulfane sulfur has physiological effects which are consistent with a role in atherogenesis. At very low concentrations, it induces proliferation of many cell types, an effect which is consistent with the fibrosis and hyperplasia, which are prominent features of atherosclerotic lesions. At higher concentrations, it is toxic. Also, it modulates the activity of many enzymes and, through this effect on enzymes of lipid metabolism, it could be responsible for the lipid accumulation seen in atherosclerotic lesions.

Sporotrichal arthritis in south central Kansas.

Sporotrichal arthritis is a rare disease, with only 51 cases reported in the English literature. Thirteen patients with sporotrichal arthritis have been treated at Wichita area hospitals since 1979. Most of the patients were middle aged men. Significant alcohol intake was noted in 77% of the patients. There were 17 joints involved in the cases, including 10 knees, three interphalangeal joints, one elbow, one midtarsal, one intercarpal, and one metatarsophalangeal joint. The typical appearance was an afebrile patient with a mildly swollen warm joint without erythema. The leukocyte counts were normal in 85% of patients, and the erythrocyte sedimentation rates were elevated in 100%. The patients had various treatments and responses. Response rates included intravenous amphotericin B (16%), ketoconazole (40%), and arthrodesis (100%). Sporotrichal arthritis may be more common than previously thought. It should be considered early in the differential diagnosis of monoarthritis.

Clinical pathway management of total knee arthroplasty.

Using a retrospective cohort study design, the authors examined complications, readmissions, morbidity and mortality, and function scores in two groups of patients attended by the same surgeon for the year before and the year after the implementation of an outcomes management program with clinical pathways for patients undergoing total knee arthroplasty at an academic health center. The effectiveness of the pathway constantly was adjusted using variance analysis and continuous quality improvement techniques. This program reduced the length of stay by 57% from a premanagement value of 10.9 +/- 5.4 days in 1994 (Group 1) to 4.7 +/- 1.4 days in 1996 (Group 2). Hospital costs (based on an inflation adjusted cost to charge ratio) for all total knees were reduced 11% from $13,328 +/- $3905 in 1994 to $11,862 +/- $4763 in 1996. Preoperative and postoperative knee scores were 41.1 +/- 16.3 and 84.2 +/- 16.0 for Group 1 and 42.5 +/- 13.0 and 87.0 +/- 10.4 for Group 2, respectively. There was no statistically significant difference between the preoperative or the postoperative knee scores of Groups 1 and 2. The application of clinical pathways, variance analysis, and continuous quality improvement toward the treatment of patients who had total knee arthroplasty at an academic health center resulted in significant savings in length of stay without adversely affecting overall outcome.

Postprandial versus preprandial blood glucose monitoring in women with gestational diabetes mellitus requiring insulin therapy.

BACKGROUND: The fetuses of women with gestational diabetes mellitus are at risk for macrosomia and its attendant complications. The best method of achieving euglycemia in these women and reducing morbidity in their infants is not known. We compared the efficacy of postprandial and preprandial monitoring in achieving glycemic control in women with gestational diabetes. METHODS: We studied 66 women with gestational diabetes mellitus who required insulin therapy at 30 weeks of gestation or earlier. The women were randomly assigned to have their diabetes managed according to the results of preprandial monitoring or postprandial monitoring (one hour after meals) of blood glucose concentrations. Both groups were also monitored with fasting blood glucose measurements. The goal of insulin therapy was a preprandial value of 60 to 105 mg per deciliter (3.3 to 5.9 mmol per liter) or a postprandial value of less than 140 mg per deciliter (7.8 mmol per liter). Obstetrical data and information on neonatal outcomes were collected. RESULTS: The prepregnancy weight, weight gain during pregnancy, gestational age at the diagnosis of diabetes and at delivery, degree of compliance with therapy, and degree of achievement of target blood glucose concentrations were similar in the two groups. The mean (+/- SD) change in the glycosylated hemoglobin value was greater in the group in which postprandial measurements were used (-3.0 +/- 2.2 percent vs. 0.6 +/- 1.6 percent, P < 0.001) and the infants' birth weight was lower (3469 +/- 668 vs. 3848 +/- 434 g, P = 0.01). Similarly, the infants born to the women in the postprandial-monitoring group had a lower rate of neonatal hypoglycemia (3 percent vs. 21 percent, P = 0.05), were less often large for gestational age (12 percent vs. 42 percent, P = 0.01) and were less often delivered by cesarean section because of cephalopelvic disproportion (12 percent vs. 36 percent, P = 0.04) than those in the preprandial-monitoring group. CONCLUSIONS: Adjustment of insulin therapy in women with gestational diabetes according to the results of postprandial, rather than preprandial, blood glucose values improves glycemic control and decreases the risk of neonatal hypoglycemia, macrosomia, and cesarean delivery.

Term early-onset neonatal seizures: obstetric characteristics, etiologic classifications, and perinatal care.

OBJECTIVE: To describe obstetric characteristics and etiologic classifications and assess perinatal care in term neonates with early-onset seizures. METHODS: We performed a retrospective review of neonatal and obstetric records of neonates delivered at term with a diagnosis of early-onset seizures between January 1981 and December 1992 at Long Beach Memorial Medical Center. Data regarding obstetric characteristics and etiologic classifications of the seizures were abstracted from the medical records. Lack of antepartum testing in high-risk patients, delayed intervention with nonreassuring antepartum or intrapartum fetal heart rate patterns, birth trauma, and failure to use prophylactic antibiotics or treat infection were the criteria used for identifying seizures that were potentially preventable. RESULTS: Forty term neonates had early-onset seizures out of 60,712 live births (0.07%). These seizures were attributed to hypoxic events in 15 neonates (37.5%), cerebral malformations in seven (17.5%), cerebral infarcts in seven (17.5%), intracranial hemorrhage in five (12.5%), infection in three, and an unknown etiology in three. Twenty-three neonates had 5-minute Apgar scores of 7 or greater (cerebral malformations excluded). Seven of these neonates (30%) had cerebral infarcts. A review of all records identified nine cases (22.5%) of the early-onset seizures as potentially preventable. CONCLUSION: The majority of the term early-onset neonatal seizures identified did not appear to be preventable. Many of the neonates with 5-minute Apgar scores of 7 or greater had cerebral infarcts.

The "dangerous multipara": fact or fiction?

OBJECTIVE: Our purpose was to compare the intrapartum complication incidence among grand multiparous women with that of age-matched control multiparous women. STUDY DESIGN: A total of 382 grand multiparous women (para > or = 5) were compared with 382 age-matched control subjects (para 2 to 4), all delivering between July 1989 and September 1991. Intrapartum complications classically associated with grand multiparity (abruptio placentae, dysfunctional labor, fetal malpresentation, postpartum hemorrhage, and shoulder dystocia) were compared. RESULT: Both groups had comparable antepartum complications and gestational ages at delivery. The overall intrapartum complication incidence for grand multiparous women was 33% (127/382 patients), not significantly different from that of the control multiparous women, 27% (103/382). Grand multiparity was associated with an increased incidence of macrosomia (16% vs 11%) and a decreased incidence of operative delivery (14% vs 21%). Macrosomia increased the incidence of intrapartum complications from 31% to 46% (p < 0.03) in the grand multiparous patients, and a trend was observed in the multiparous patients, from 26% to 37%. However, when properly controlled, this was noted to be a confounding variable and was not related to parity. CONCLUSIONS: In a largely Hispanic population grand multiparous patients do not have an increased incidence of intrapartum complications.

Pulmonary injury associated with appendicitis in pregnancy: who is at risk?

OBJECTIVE: Our purpose was to determine risk factors for pulmonary injury in women with antepartum appendicitis. STUDY DESIGN: This case-control study included 49 patients with appendicitis during pregnancy. Patients who had pulmonary injury composed the study group (n = 9); the control subjects had no injury (n = 40). Records were abstracted for gestational age at surgery, type of anesthesia, presenting symptoms, findings on physical examination, vital signs, laboratory test results, use of tocolytics or antibiotics, and fluid management. Pulmonary injury was characterized by dyspnea, tachypnea, PaO2 < or = 70 mm Hg, and an abnormality on chest radiography. RESULTS: Pulmonary injury developed in nine study patients (18%) (adult respiratory distress syndrome, n = 2; pulmonary edema or infiltrates, n = 7) as a complication of appendicitis during pregnancy. All study group patients were at > 20 weeks' gestation compared with 27 of 40 (67%) control subjects (p = 0.05). Univariate analysis showed that fluid overload > or = 4 L, maximum respiratory rate > 24 breaths/min, maximum heart rate > 110 beats/min, maximum temperature > or = 100.4 degrees F, general anesthesia, and tocolytic use were significant (p < 0.005). By multivariate analysis with the use of stepwise logistic regression a model of fluid overload > or = 4 L, respiratory rate > 24 breaths/min, maximum temperature > or = 100.4 degrees F, and tocolytic usage would predict 99% of injury cases. CONCLUSIONS: Iatrogenic factors such as injudicious fluid management and tocolytic use can greatly increase the risk for pulmonary injury with antepartum appendicitis.

Pseudomonas osteomyelitis following puncture wounds of the foot.

The management of puncture wounds of the foot should include routine wound care, tetanus prophylaxis and warnings of what to look for and expect. Pseudomonas aeruginosa is the most commonly recovered organism in puncture wounds. Should symptoms develop, aggressive intravenous antibiotic treatment should be initiated if symptoms occur within seven days. Clinical presentation is characterized by minimal systemic symptoms, few laboratory abnormalities, and asymptomatic patients until the obvious presentation of osteomyelitis. After seven to 14 days, the would should be surgically treated and appropriate antibiotics administered.

External fixation of unstable Malgaigne fractures: the comparative mechanical performance of a new configuration.

An external fixator has been designed that is rigid enough to eliminate the need for skeletal traction in patients with unstable pelvic-ring fractures. This Wichita frame is similar to the Pittsburgh frame but is stiffened by the use of locked crossbars connecting the side triangles. The frame was tested in cadaveric specimens by techniques previously reported. In addition, finite-element modeling of the various frame designs was performed to ensure that the frame configuration was optimal and to supplement in vitro test results. Multiple variables that can influence frame failure loads were examined.

Does amniotic fluid index affect the accuracy of estimated fetal weight in preterm premature rupture of membranes?

Estimated fetal weights play a critical role in the management scheme of patients with preterm premature rupture of membranes but are often technically difficult to obtain in these patients because of low amniotic fluid volume. Previous studies have had conflicting data as to the accuracy of estimated fetal weights in preterm premature rupture of membranes. This study was undertaken to evaluate the effect of amniotic fluid index on the accuracy of estimated fetal weights in pregnancies complicated by preterm premature rupture of membranes. Over a 2-year period at Long Beach Memorial Medical Center, 98 patients with preterm premature rupture of membranes who had an ultrasonographic examination with estimated fetal weights and amniotic fluid index performed within 48 hours of delivery were identified and compared with a control group of 55 patients in preterm labor with normal amniotic fluid index for gestational age, also obtained within 48 hours of delivery. Shepard and Hadlock formulas were used to estimate fetal weight. Results were measured in percent error from the actual birth weight. All birth weights were less than 2000 gm. No statistical differences were identified. The value of amniotic fluid index did not affect the accuracy of predicted estimated fetal weight in preterm premature rupture of membranes. Predicted estimated fetal weight of patients with preterm premature rupture of membranes appears to be as accurate as predicted estimated fetal weight in pregnancies with normal amniotic fluid volumes.

A long-term follow-up study of tibiotalar dislocations without associated fractures.

A retrospective review of 19 cases of pure tibiotalar dislocation without associated fractures showed that most patients with closed injuries will have a good long-term result. Closed injuries generally have functionally insignificant instability, loss of motion, and no roentgenographic evidence of degenerative changes. The long-term results were worse in open dislocations that had a high incidence of concurrent neurovascular injury. These neurovascular injuries were of minimal functional significance. The role of primary ligament repair is difficult to delineate.

Effect of dimethylthiourea on plasma paraquat concentration.

In a previous study, administration of the hydroxyl radical scavenger, dimethylthiourea (DMTU), and paraquat was associated with higher mortality in rats than was paraquat alone. In the present study, the possibility was evaluated that administration of DMTU increased plasma paraquat levels. Plasma paraquat concentrations were measured in Sprague-Dawley rats 1, 2, 4, 8 and 24 h after intraperitoneal (i.p.) injection of 29 mg paraquat cation/kg body wt. Another group of rats was treated identically except that they received i.p. injections of DMTU before injections of paraquat. Administration of DMTU was associated with increased plasma paraquat concentration (P less than 0.01). Pharmacokinetic analyses indicated that, compared to rats receiving paraquat alone, rats given paraquat and DMTU showed: (1) greater area under the paraquat concentration time-curve; (2) lower total body paraquat clearance; and (3) smaller apparent volume of distribution. Plasma biochemical studies indicated that paraquat caused hyperglycemia as well as an early reduction (compared to controls) in hepatic enzymes. We conclude that: (1) DMTU administration is associated with increased plasma paraquat concentrations; and (2) impaired synthesis or inhibition of release of hepatic proteins may be an early effect of paraquat.
