Administer a single dose for early syphilis (less than 2 years) buy ventolin 100mcg with visa; one injection per week for 3 weeks for late syphilis (more than 2 years) or if the duration of infection is unknown purchase 100 mcg ventolin fast delivery. Treatment of the partner The sexual partner receives the same treatment as the patient, whether or not symptoms are present, except in the case of genital herpes (the partner is treated only if symptomatic). Gynaecological examination should be routinely performed: – Inspection of the vulva, speculum examination: check for purulent discharge or inflammation, and – Abdominal exam and bimanual pelvic exam: check for pain on mobilising the cervix. If peritonitis or pelvic abscess is suspected, request a surgical opinion while initiating antibiotic therapy. Clinical features Sexually transmitted infections Diagnosis may be difficult, as clinical presentation is variable. Infections after childbirth or abortion – Most cases present with a typical clinical picture, developing within 2 to 10 days after delivery (caesarean section or vaginal delivery) or abortion (spontaneous or induced): • Fever, generally high • Abdominal or pelvic pain • Malodorous or purulent lochia • Enlarged, soft and/or tender uterus – Check for retained placenta. Treatment – Criteria for hospitalisation include: • Clinical suspicion of severe or complicated infection (e. They should be reassessed routinely on the third day of treatment to evaluate clinical improvement (decrease in pain, absence of fever). If it is difficult to organise routine follow-up, advise patients to return to clinic if there is no improvement after 48 hours of treatment, or sooner if their condition is worsening. Infections after childbirth or abortion – Antibiotic therapy: treatment must cover the most frequent causative organisms: anaerobes, Gram negatives and streptococci. Depending on the formulation of co- amoxiclav available: Ratio 8:1: 3000 mg/day = 2 tablets of 500/62. Stop antibiotic therapy 48 hours after resolution of fever and improvement in pain. In penicillin-allergic patients, use clindamycin (2700 mg/day in 3 divided doses or injections) + gentamicin (6 mg/kg once daily). Clinical features – Venereal warts are soft, raised, painless growths, sometimes clustered (cauliflower- like appearance) or macules (flat warts), which are more difficult to discern. Speculum exam may reveal a friable, fungating tumour on the cervix, suggestive of cancer associated with papilloma virus. Explain the procedure to the patient: apply the solution to the warts using an applicator or cotton bud, sparing the surrounding healthy skin, allow to air dry. On vaginal warts, the solution should be allowed to dry before the speculum is withdrawn. Podophyllum preparations are contra-indicated in pregnantc or breastfeeding women. They should not be applied on cervical, intra-urethral, rectal, oral or extensive warts. Presence of genital warts in women is an indication to screen for pre- cancerous lesions of the cervix, if feasible in the context (visual inspection with acetic acid, or cervical smear, or other available techniques), and to treat any lesions identified (cryotherapy, conisation, etc. Protect the surrounding skin (vaseline or zinc oxide ointment) before applying the resin. Genital warts are not an indication for caesarean section: it is uncommon for warts to interfere with delivery, and the risk of mother-to-child transmission is very low. Recurrences in 1/3 of infections with shorter and • Recurrent infections: same dose for 5 days, given milder symptoms. Human Soft, raised, painless growths, sometimes clustered The diagnosis is based on clinical • External warts < 3 cm and vaginal warts: papillomavirus (acuminate condyloma) or macules (flat warts). It should not be administered to breast-feeding women if the treatment exceeds 7 days (use erythromycin). In women of childbearing age, always assess if the bleeding is related to a pregnancy. Bleeding unrelated to pregnancy – Clinical examination: • speculum examination: determine the origin of the bleeding [vagina, cervix, uterine cavity]; appearance of the cervix; estimation of blood loss; • bimanual pelvic examination: look for uterine motion tenderness, increased volume or abnormalities of the uterus. While waiting for surgery or if surgery is not indicated, treat as a functional uterine bleeding. Note: rule out other causes of vaginal bleeding before diagnosing functional uterine bleeding. Consider for example poorly tolerated contraceptive, endometrial cancer in postmenopausal women, genitourinary schistosomiasis in endemic areas (see Schistosomiasis, Chapter 6). Ectopic pregnancy Pregnancy that develops outside the uterus, very often in a fallopian tube. Ectopic pregnancy should be suspected in any woman of reproductive age with pelvic pain and/or metrorrhagia. There are many possible clinical presentations and these can mislead diagnosis towards appendicitis, intestinal obstruction, salpingitis or abortion. The major risk of ectopic pregnancy is rupture, leading to intra abdominal haemorrhage. Clinical features and diagnosis – Amenorrhoea (may be absent) or menstrual irregularity. If ultrasound shows an empty uterus together with intra peritoneal effusion, an ectopic pregnancy is likely, especially if the pregnancy test is positive.

Cryptosporidium can also infect other gastrointestinal and extraintestinal sites, especially in individuals whose immune systems are suppressed. The three species that most commonly infect humans are Cryptosporidium hominis, Cryptosporidium parvum, and Cryptosporidium meleagridis. Viable oocysts in feces can be transmitted directly through contact with infected humans or animals, particularly those with diarrhea. Oocysts can contaminate recreational water sources such as swimming pools and lakes, and public water supplies and may persist despite standard chlorination (see Appendix: Food and Water-Related Exposures). Person-to-person transmission is common, especially among sexually active men who have sex with men. Clinical Manifestations Patients with cryptosporidiosis most commonly have acute or subacute onset of watery diarrhea, which may be accompanied by nausea, vomiting, and lower abdominal cramping. More severe symptoms tend to occur in immune-suppressed patients, whereas transient diarrhea alone is typical in hosts with competent immune systems. Fever is present in approximately one-third of patients and malabsorption is common. Antigen-detection by enzyme-linked immunosorbent assay or immunochromatographic tests also are useful, with sensitivities reportedly ranging from 66% to 100%, depending on the specific test. Cryptosporidial enteritis also can be diagnosed from small sections from intestinal biopsy. A single stool specimen is usually adequate for diagnosis in individuals with profuse diarrheal illness, whereas repeat stool sampling is recommended for those with milder disease. Modes of transmission include having direct contact with infected adults, diaper- aged children, and infected animals; coming into contact with contaminated water during recreational activities; drinking contaminated water; and eating contaminated food. Paying attention to hygiene and avoiding direct contact with stool are important when visiting premises such as farms or petting zoos where these animals are housed or exhibited. Waterborne infection also can result from swallowing water during recreational activities. Outbreaks of cryptosporidiosis have been linked to drinking water from municipal water supplies. These include working directly with people with diarrhea; with farm animals such as cattle and sheep; and with domestic pets that are very young or have diarrhea. If exposure is unavoidable, gloves should be used and practices for good hand hygiene observed. Rifabutin and possibly clarithromycin, when taken for Mycobacterium avium complex prophylaxis, have been found to protect against cryptosporidiosis. Rehydration and repletion of electrolyte losses by either the oral or intravenous route are important. Patients with biliary tract involvement may require endoscopic retrograde choledocoduodenoscopy for diagnosis. Food and Drug Administration for treatment of cryptosporidiosis in children and adults. Paromomycin is a non-absorbable aminoglycoside indicated for the treatment of intestinal amebiasis but not specifically approved for cryptosporidiosis. It is effective in high doses for the treatment of cryptosporidiosis in animal models. Preventing Recurrence No pharmacologic interventions are known to be effective in preventing the recurrence of cryptosporidiosis. Limited information is available about the teratogenic potential of paromomycin, but oral administration is associated with minimal systemic absorption, which may minimize potential risk.
