Approximately 40% of the world population live in malarious areas, particularly in equatorial regions. Malaria is transmitted to humans in the saliva of the anopheles mosquito and is caused by protozoan organisms of the genus Plasmodium. Malaria is one of the most common causes of serious illness in the returning traveller. Air travel and the incubation period of the disease have raised the awareness of diagnosing and appropriately treating malaria even in areas where it is not endemic. Visitors to endemic areas must be warned of the infection risk and advised that prophylactic drug therapy should be taken, but that it is not 100% effective. They should also be advised to wear long-sleeved clothing to cover extremities (especially in the evenings, when mosquitos feed) to use mosquito-repellent sprays, to sleep in properly screened rooms with mosquito nets (impregnated with pyrethroids) around the bed and/or to burn and vapourize synthetic pyrethroids during the night. In addition to chemoprophylactic drug therapy, travellers to remote areas should be advised to carry standby antimalarial drug treatment with quinine. Where there is doubt concerning the suitability of drug therapy for malaria prophylaxis or treatment, the malaria reference laboratory at the London School of Hygiene and Tropical Medicine has advice and guidance (Tel. Prophylaxis must start at least one week (and preferably two weeks) before entering a malaria endemic region, and must continue for four weeks afterwards. Chloroquine is only used as a prophylactic in regions where falciparum malaria is not chloroquine resistant. Drugs for the prophylaxis of chloroquine-resistant falciparum malaria are shown below; items 3 and 4 appear to be well tolerated. Antimalarial mechanism of action the erythrocyte stages of Plasmodium are sensitive to chloroquine. At this stage of its life cycle, the parasite digests haemoglobin in a food vacuole to provide energy for the parasite. The food vacuole is acidic and the weak base chloroquine is concentrated within it by diffusion ion-trapping. The choice of chemoprophylaxis regimen is dependent on the dominant local parasite species and its drug resistance profile. Chemoprophylaxis must start before, and continue after, travel to and from an endemic area. Drug choice and doses may need to be altered in patients with renal or hepatic dysfunction. About 70% of a dose is excreted unchanged in the urine, and the main metabolite is desethylchloroquine. High tissue concentrations (relative to plasma) are found, especially in melanin containing tissues. Quinine should not be used for nocturnal cramps as its adverse effects outweigh any benefit in this benign condition. Drug interactions Chloroquine and quinine are antagonistic and should not used in combination. The mechanism of its antimalarial activity remains unclear, but may be similar to that of chloroquine. Initially, these drugs may be given intravenously and then orally when the patient improves. The mean t1/2 is quite long and in patients with renal or hepatic dysfunction dosing should be reduced to Table 47.

There is unequivocally a much higher rate of caesarean section in these cases and many clinicians will recommend elective caesarean section rather than a trial of labour, but both options are reasonable. Antepartum haemorrhage (Ch 10) A major degree of placenta praevia requires caesarean section. If the lower placental edge impinges on the lower uterine segment but is more than 2 cm away from the internal cervical os, vaginal birth may still be possible. A severe abruption is defined as sufficient placental separation to cause fetal death. Both strategies probably have a place, and a considered recommendation should be made given an understanding of the pathophysiology and the circumstances of the individual case. Caesarean section on maternal request Increasingly, some women are requesting caesarean section in the absence of a specific additional risk to mother or fetus. Most clinicians will respond favourably to such a request but have an obligation to ensure that the decision is a well-informed one. In particular, the woman should be apprised of the pros and cons of her request; of prime importance would be the future risk of placenta accreta if high parity is intended. Severe preeclampsia and eclampsia (Ch 16) Preeclampsia is not in itself an indication for caesarean section. However, when severe preeclampsia occurs at very or extreme preterm gestations, the cervix is commonly unripe and in the presence of preeclampsiaassociated placental insufficiency, induction of labour without fetal compromise is often unachievable and a caesarean section is the preferred option. The gestation selected for a repeat elective caesarean section is usually at approximately 39 weeks, balancing the risk of neonatal respiratory distress against the undesirability of performing the procedure so late that the woman comes into labour and the operation then done as an emergency with increased attendant risks. If the operation is in the afternoon, she can have a light breakfast at least six hours before planned surgery. Only 1% of women will require a blood transfusion because of excessive haemorrhage at elective caesarean section; it is noteworthy that this rate is less than the rate of transfusion after vaginal delivery! In active labour, gastric emptying is delayed, and so emergency caesarean section is always regarded as having a risk of aspiration of gastric contents. Regional analgesia, usually spinal, is the safest technique for mother and baby, and is used in the vast majority of elective procedures and in emergency procedures where possible if there is no existing epidural block. It is uncommon for general anaesthesia to be necessary, and it has many disadvantages (Ch 38). In addition, the resulting haemoconcentration and trauma predispose to thromboembolism. Antibiotic prophylaxis at the time of caesarean section significantly reduces the incidence of endometritis and wound infection. Early administration is most effective in preventing infection but risks anaphylaxis with the fetus in utero-with potentially disastrous consequences for the fetus. There is no evidence that combinations of antibiotics or more than one dose offer any advantage over a single dose of one antibiotic. Allis); needle holders; sucker and tubing; diathermy; needles; sutures; sponge forceps; scalpel handles; scalpel blades; curved artery forceps; straight artery forceps; toothed dissecting forceps; swabs; and packs (should have a radio-opaque strip). Suction is required for the anaesthetist and operator and for neonatal resuscitation. A neonatal resuscitation table is set aside for the management of the infant after birth. The bellies of the rectus muscle are then separated and the peritoneal cavity entered. The lower segment is exposed with the aid of a curved retractor and the loose peritoneum over it is cut with curved scissors. The muscle of the lower segment is incised with a scalpel in a transverse direction. The initial incision is extended either with scissors or by stretching with fingers at each angle.

Finally, couples should be made aware of fertile timing as well as symptoms of ovulation to ensure that further attempts to conceive are timed appropriately while undergoing the infertility evaluation. Treatment of any pathology identified, withdrawal of exogenous anabolic steroids and/or administration of gonadotrophins via injection may restore spermatogenesis, although this may take many months or longer to occur. Testicular failure Impaired spermatogenesis may occur despite normal or high levels of endogenous gonadotrophins, suggesting testicular dysfunction. Other congenital disorders include undescended testes, testicular dysgenesis or anorchia. Testicular torsion, trauma, and orchitis (for instance, due to mumps) can all cause hypergonadotrophic hypogonadism. Similarly, exposure to gonadotoxins such as chemotherapy or radiotherapy can result in a similar picture. Therefore, the semen analysis is fundamental to the evaluation of the male factor. However, a number of disorders can impact on the semen parameters and it is important to recognise that any severe intercurrent illness will cause a transient reduction in sperm quality and quantity even in the normal, healthy male. Therefore, an initial abnormal semen analysis should be repeated to confirm if any abnormality is transient or persistent. Karyotype should be performed, as well as specific tests to identify Y chromosome microdeletions. Obstructive disorders Physical obstruction to the passage of sperm from the site of production can be due to congenital or acquired bilateral lesions of the seminal ducts. Obstructive disorders are less common than non-obstructive causes of azoospermia, accounting for 10 to 20% of all azoospermia. Obstruction can occur at the level of the epididymis, vas deferens or ejaculatory ducts. The site of obstruction for the majority of these normogonadotrophic men will be the epididymis, and the obstruction is most commonly acquired due to previous trauma or inflammation such as epididymitis. Congenital bilateral absence of the vas deferens can occur and is associated with the cystic fibrosis carrier state. Thus, cystic fibrosis testing for these patients and their partners is extremely important to gauge any potential risk to the fetus. Previous surgery may also result in obstruction, such as removal of epididymal cysts or, rarely, after hernia repair, while a small but significant number of men seek treatment having previously undergone vasectomy for permanent contraception. Hypothalamo-pituitary dysfunction Dysfunction at the hypothalamus and pituitary can result in disordered spermatogenesis, although this is a relatively rare cause for infertility in the male. This includes hyperprolactinaemia, infiltrative disorders of the pituitary and pituitary tumours. Anabolic steroid abuse will also result in hypogonadotrophic hypogonadism due to the negative feedback of high androgen levels. Pathophysiological classification of anovulation Anovulation can be further divided into three areas: 1. This is usually accompanied by absent or irregular menstruation, which normally depends on oestrogen production from the developing follicle followed by progesterone secretion and withdrawal from the corpus luteum. Monitoring of the basal body temperature can also detect the progesterone mediated rise in temperature of 0. However, the more convenient and reliable means of detecting ovulation is a serum progesterone measurement in the mid-luteal phase of those with regular cycles. This would be on day 21 of the normal 28-day cycle or 7 days prior to anticipated menstruation in cycles of different lengths. For those with regular periods but of occasionally varying length, serum progesterone may be repeated serially in the luteal phase to identify ovulation that may occur later than predicted. A progesterone level over 20 nmol/L in the mid-luteal phase is a reliable indicator that ovulation has occurred. Hypothalamic dysfunction Hypothalamic dysfunction occurs in situations of stress, overexercise and weight loss that is either sudden or severe, or in the situation of very low body weight. Hyper- and hypothyroidism can also cause disruption to the central regulation of ovulation. However, in contrast to central causes of amenorrhoea, there is a normal serum 37. Pituitary dysfunction Dysfunction may also occur at the level of the pituitary gland.

This condition is extremely rare with active management of the third stage of labour including the routine administration of an oxytocic. Uterine inversion usually occurs in the presence of a fundal placenta with cord traction applied to an uncontracted uterus (Fig 36. Traction on the cord when the uterus is atonic and the placenta not separated produces initial dimpling of the fundus A and then inversion of the uterus through the cervix B. Activation of the endothelium with vasospasm, platelet aggregation and clot formation are all important as well. In obstetric practice, disseminated intravascular coagulation is easily the most common cause of failure of blood clotting. The clinical conditions predisposing to this complication are placental abruption, fetal death in utero (more than 4 weeks), severe preeclampsia, amniotic fluid embolism, chorioamnionitis and sustained hypotension with poor tissue perfusion for any reason (Ch 20). All of these conditions act by massive release of thromboplastin into the circulation. Occasionally, other conditions such as severe thrombocytopenia or hereditary disorders of coagulation. In all of these conditions, correction of the underlying haematological disturbance will be key to controlling the blood loss. In general, tears of the uterus, cervix and upper vagina are more serious, because of the larger vessels that may be torn and the difficulty in gaining access to them. More common and usually more manageable are tears of the lower vagina, introitus and perineum. A high tear should be suspected if bleeding is coming down from the upper vagina immediately after birth and before any separation of the placenta. Uterine rupture at the site of a previous classical caesarean section scar (subtotal hysterectomy specimen). Rupture may also occur after operation on the non-pregnant uterus, including myomectomy or perforation of the uterus at the time of curettage. Obstructed labour Neglected obstructed labour may result in a uterine rupture, particularly as the parity increases. The lower uterine segment progressively thins as it is drawn up over the presenting part. Trauma A high-speed motor vehicle accident may cause uterine rupture, as may obstetric manipulation. The mother will experience pain at the site of rupture followed by evidence of intraperitoneal bleeding. Rupture may present after a vaginal birth as persistent ongoing bleeding or unexpected maternal collapse. Two large ribbon gauze packs are tied together, moistened with obstetric cream and firmly packed, beginning high in the vagina. Since the packing occludes the urethra, an indwelling (Foley) catheter is required and a uterine balloon with catheter drainage may help reveal ongoing uterine bleeding. The pack is removed 12 to 24 hours later and healing of any unsutured vaginal lacerations is usually quite satisfactory. Low vaginal, introital and perineal tears Tears may occur almost anywhere, including involving the anterior compartment of the perineum (around the urethra and clitoris) and posteriorly involving the sphincter and anal canal. Particularly heavy bleeding may result from an annular avulsion of the vulva from the lower vagina. Tears are more common where the fetus is large or the head extended, where delivery is rapid or instrumental (not allowing time for tissues to stretch) or where there is a need for difficult manipulations. Where the anal sphincter is involved, this must be clearly identified and repaired in theatre with good lighting and adequate anaesthesia. Where there is persistent bleeding from deep in the perineum, packing is not possible because there is nothing to pack against. Treatment Apart from the usual measures for haemorrhagic shock, a uterine rupture will usually require hysterectomy, although a small defect may be successfully repaired- albeit with a significant likelihood of rupture in a subsequent pregnancy. If this is not effective, epidural anaesthesia will quell the desire to push against a cervix that is not fully dilated. Instrumental vaginal birth (especially rotational forceps), internal podalic version (usually for a second twin) and treatment of impacted shoulders are all manipulations that may tear the cervix.
