Association between history of abdominopelvic surgery and tubal pathology

Background

Pelvic infection, unsafe abortion and previous laparatomy are risk factors for tubal infertility among Nigerian women. Reports on the relationship between these factors and tubal pathology seen on hysterosalpingography (HSG) from our environment have been few.

Objective

To assess the prevalence of tubal occlusions among patients referred for HSG and examine the association between previous history of abdominopelvic surgery (including dilatation and curettage for abortion) and tubal occlusion.

Methods

We studied one hundred and thirty women referred to the Radiology department for HSG because of infertility. HSG was performed during the early proliferative phase of the menstrual cycle. Information about type and duration of infertility, history of abdomino -pelvic surgery and history suggestive of previous pelvic infection, were obtained from the patients. The data obtained were analyzed using SPSS version 11. Test of association using the chi-square test was done where appropriate and differences were considered at p= 0.05.

Results

Sixty one women had bilaterally patent tubes; tubal pathology was seen in sixty nine women. Significant association exits between tubal pathology and history of pelvic surgery p=0.01, pelvic infection p=0.02 and duration of infertility p=0.04.

Conclusion

Previous surgery especially dilation and curettage, PID duration and type of infertility are associated with tubal pathology among Nigerian women. Creative methods of lowering the cost of diagnosis and management of tubal occlusion need to be instituted.     

Diagnostic image quality of hysterosalpingography: ionic versus non ionic water soluble iodinated contrast media

Objective

To compare the diagnostic image quality between three different water soluble iodinated contrast media in hysterosalpingography (HSG).

Material and method

In a prospective randomised study of 204 patients, the diagnostic quality of images obtained after hysterosalpingography were evaluated using Iopramide (106 patients) and Ioxaglate (98 patients). 114 patients who had undergone HSG examination using Iodamide were analysed retrospectively. Image quality was assessed by three radiologists independently based on an objective set of criteria. The obtained results were statistically analysed using Kruskal-Wallis and Mann-Whitney U test.

Results

Visualisation of fimbrial rugae was significantly better with Iopramide and Ioxaglate than Iodamide. All contrast media provided acceptable diagnostic image quality with regard to uterine, fallopian tubes outline and peritoneal spill. Uterine opacification was noted to be too dense in all three contrast media and not optimal for the assessment of intrauterine pathology. Higher incidence of contrast intravasation was noted in the Iodamide group. Similarly, the numbers of patients diagnosed with bilateral blocked fallopian tubes were also higher in the Iodamide group.

Conclusion

HSG using low osmolar contrast media (Iopramide and Ioxaglate) demonstrated diagnostic image qualities similar to HSG using conventional high osmolar contrast media (Iodamide). However, all three contrast media were found to be too dense for the detection of intrauterine pathology. Better visualisation of the fimbrial outline using Ioxaglate and Iopramide were attributed to their low contrast viscosity. The increased incidence of contrast media intravasation and bilateral tubal blockage using Iodamide are probably related to the high viscosity.     

Open Access Tubal aSsessment for the initial management of infertility in general practice (the OATS trial): a pragmatic cluster randomised controlled trial

Background

GPs investigate approximately half of all infertile couples with semen analysis and endocrine blood tests. For assessment of tubal status, hysterosalpingography (HSG) is recommended as a first-line investigation for women not known to have comorbidities.

Aim

To test whether providing GPs with open access to HSG results in infertile couples progressing to a diagnosis and management plan sooner than with usual management.

Design of study

A pragmatic cluster randomised controlled trial.

Setting

Seventy-one of 173 general practices in north-east England agreed to participate.

Method

A total of 670 infertile couples presented to 33 intervention practices and 25 control practices over a 2-year period. Practices allocated to the intervention group had access to HSG for those infertile women who fulfilled predefined eligibility criteria. The primary outcome measure was the interval between presentation to the GP and the couple receiving a diagnosis and management plan.

Results

An annual incidence of 0.8 couples per 1000 total population equated to each GP seeing an average of one or two infertile couples each year. Open access HSG was used for 9% of all infertile women who presented to the intervention practices during the study period. The time to reach a diagnosis and management plan for all infertile couples presenting was not affected by the availability of open access HSG (Cox regression hazard ratio = 0.9, 95% confidence interval [CI] = 0.7 to 1.1). For couples who reached a diagnosis and management plan, there was a non-significant difference in time to primary outcome for intervention versus control practices (32.5 weeks versus 30.5 weeks, mean difference 2.2 weeks, 95% CI = 1.6 to 6.1 weeks, P = 0.1). The intracluster correlation coefficient was 0.03 across all practices.

Conclusion

Providing GPs with open access to HSG had no effect on the time taken to reach a diagnosis and management plan for couples with infertility.     

Patient and professional views of open access hysterosalpingography for the initial management of infertility in primary care

Background

Hysterosalpingography (HSG) is recommended as a first-line investigation for tubal assessment of infertile women. This investigation is not routinely available to GPs.

Aim

To explore the perceptions and attitudes of patients and health professionals to open access HSG for the initial management of infertile couples in general practice.

Design of study

A nested qualitative study using in-depth interviews with GPs, fertility specialists, and infertile couples.

Setting

Northumberland, Newcastle upon Tyne, North Tyneside, South Tyneside, and Gateshead.

Method

Participants were 39 interviewees: 12 GPs, five fertility specialists, and 13 infertile couples (nine interviewed with their partner).

Results

Four themes emerged: personal factors; will it benefit patients, GPs, and fertility specialists?; professional factors; does it fit the role of a GP?; local context; do the skills exist in general practice?; and wider context; will it benefit the NHS? GPs who had used open access HSG, felt it was appropriate for general practice and would continue to use the service. All GPs, fertility specialists, and infertile couples who had experienced open access HSG wished the service to remain in place. The main barriers to its uptake were: infrequency with which infertility presents; lack of clarity on perceived responsibilities; difficulty keeping up to date, including assimilating guidelines; low clinical priority; and lack of support in authoritative guidance.

Conclusion

Providing GPs with open access to HSG would allow a full initial assessment of the infertile couple and refer women with blocked tubes directly to tertiary care. While there is general support for the provision of such a facility, the majority of GPs perceive its use as being by a limited number of GPs who have a special interest in infertility. The study findings can inform future development of infertility services at the interface between primary and secondary/tertiary care.     

The pattern and challenges of infertility management in Lagos,Nigeria

Background

Infertility remains a threat to successful reproduction by couples desirous of pregnancy.

Objective

To determine the pattern of infertility cases amongst infertile couples seeking care in Lagos University Teaching Hospital as well as challenges in their management.

Methods

A review of the management of couples referred for infertility to the gynaecological outpatient clinic of the Lagos University Teaching Hospital (LUTH), Nigeria from 1^st January 2005 to 31^st December 2006.

Results

The incidence of infertility was found to be 26.8% of the gynaecological consultations with a mean duration of infertility of 4.3 ± 3.4 years. The mean age of the women was 33.8 ± 5.2 years and 66.1% were nulliparous. Secondary infertility accounted for 80% of cases. Male factors only was the cause in 11.1%, female factor only in 37.8%, both male and female factors in 40% while no cause was identifiable in 11.1%. There was no association between tubal occlusion and a history of induced abortion in this study (p >0.05). There was a high rate of discontinuation of care by their large numbers lost to follow up.

Conclusion

Infertility is still a public health problem in Lagos, Nigeria.     

Prevalence of overweight and obesity in young adults in Uganda

Background:

Obesity in young adults is rising and predicts diabetes and cardiovascular diseases later in life. Data on prevalence and determinants of obesity in developing countries are needed for primary prevention.

Objectives

To determine the prevalence of overweight and obesity in young adults in urban (Kampala city) and rural areas (Kamuli District) of Uganda.

Methods

Cross-sectional survey of 683 randomly selected young adults aged 18–30 years. Obesity was defined as body mass index (BMI) > 30 kg/m² and overweight as BMI > 25 kg/m². Distribution of BMI by socio-demographic characteristics was determined.

Results

Of the 683 participants, 50.5% were female and 53.2% were from Kampala. The overall prevalence of obesity and overweight was 2.3% and 10.4%, respectively. The prevalence of obesity was 4.4% in Kampala and 0% in Kamuli while the prevalence of overweight was 10.2% and 10.6% in Kampala and Kamuli, respectively. Compared to males, females were more likely to be obese (2.9% vs. 1.8%) or overweight (17.4% vs. 3.3%). Residing in the city, alcohol consumption, smoking, non-engagement in sports activities, commuting to school by taxi or private vehicle and being from a rich family were the main factors significantly associated (P<0.05) with obesity. Being female (p = 0.0001) and not engaging in any sports activities (P = 0.002) were two factors significantly associated with being overweight.

Conclusion

We observed significant gender differences in the prevalence of obesity among young adults in Uganda. Contrary to expectation, we did not observe significant rural-urban differences in the prevalence of overweight.     

The accuracy of self monitoring blood glucose meter systems in Kampala Uganda

Background

Many blood glucose self-monitoring systems are privately and publicly used by people in Uganda and technical and human errors may occur during their operation. Many patients were referred to Kololo polyclinic laboratory to have their blood glucose checked because the values obtained on the patients'' glucose meter systems did not tally with familiar clinical signs and symptoms. This prompted an experimental set up to check glucose meter systems using a larger number of patients.

Objective

The objective was to collate the technical conditions and standing operational procedures of four common glucose meter systems; observe the time, ambient temperature and humidity at which the meter systems operate locally; and compare the performance of three meter systems A, B, and C with the Sensorex glucose meter system on a number of capillary blood samples.

Setting

Kololo polyclinic laboratory-a privately run facility in Kampala, Uganda.

Design

An experimental set up to compare four glucose meter systems.

Methods

Instruction manuals of the four glucose monitoring systems were studied and used to familiarize with the meter operations. One hundred and fourteen capillary blood specimens were assayed for blood glucose. Blood glucose values were instantly read off the four randomly set meter systems A, B, C, and Sensorex, noting the time, ambient temperature and humidity. Results from meter systems A, B, and C were regressed against those of Sensorex using Epi-Info computer program.

Results

Blood glucose concentration levels on meter system A tallied with those on Sensorex meter system. However, those on meter system B and C were significantly lower and different. Temperature and humidity adversely affected the analytical performance of meter systems B and C in the Kampala environ.

Conclusion

Some of the blood glucose monitoring systems in Kampala, Uganda are poor performers and may lead to the mismanagement of patients. There is need for a system to ensure national quality control of blood glucose monitoring systems.     

Brucella sero-prevalence and modifiable risk factors among predisposed cattle keepers and consumers of un-pasteurized milk in Mbarara and Kampala districts,Uganda

Background

Brucellosis is an important zoonotic disease in developing countries yet it is often not recognized, goes unreported and does not attract public health action by these governments including Uganda.

Objective

To estimate the sero-prevalence and assess modifiable risk factors associated with Brucella seropositivity in cattle keepers and consumers of unpasteurized milk in Uganda.

Methods

One group comprised of 161 individuals randomly selected from households living on farms that had Brucella sero-positive cattle and/or goats in Mbarara District from an earlier survey; the second group comprised of 168 randomly selected individuals attending an HIV voluntary counseling and testing clinic in Kampala District. Sera samples were tested using Rapid Plate Agglutination Test, Standard Tube Agglutination Test and cELISA.

Results

The sero-prevalence of brucellosis among exposed cattle keepers in Mbarara and consumers of unpasteurised milk in Kampala Districts was 5.8% (95%CI: 3.3%, 8.3%) and 9% (95%CI: 13.3%, 4.7%), respectively. Consumption of unboiled milk was significantly (p=0.004) associated with seropositivity in Mbarara District. There was no association between sero-positivity with age, sex and awareness of human brucellosis.

Conclusion

Human brucellosis is prevalent among livestock rearing communities and consumers of unpasteurised milk. The continued consumption of unboiled milk is a major health risk.     

Fallopian tube origin of supposed ovarian high-grade serous carcinomas

INTRODUCTION:

Serous carcinomas are the most frequent histologic type of ovarian and peritoneal cancers, and can also be detected in the endometrium and fallopian tubes. Serous carcinomas are usually high‐grade neoplasms when diagnosed, yet the identification of an associated precursor lesion remains challenging. Pathological examination of specimens obtained from prophylactic bilateral salpingo‐oophorectomies that were performed for patients harboring BRCA1/2 mutations suggests that high‐grade serous carcinomas may arise in the fallopian tubes rather than in the ovaries.

OBJECTIVE:

To investigate the presence and extent of fallopian tube involvement in cases of serous pelvic carcinomas.

METHODS:

Thirty‐four cases of serous pelvic carcinoma with clinical presentations suggesting an ovarian origin were analyzed retrospectively. Histologic samples of fallopian tube tissues were available for these cases and were analyzed. Probable primary site, type of tubal involvement, tissues involved in the neoplasia and vascular involvement were evaluated.

RESULTS:

Fallopian tube involvement was observed in 24/34 (70.6%) cases. In 4 (11.8%) of these cases, an intraepithelial neoplasia was present, and therefore these cases were hypothesized to be primary from fallopian tubes. For an additional 7/34 (20.6%) cases, a fallopian tube origin was considered a possible primary.

CONCLUSIONS:

Fallopian tubes can be the primary site for a subset of pelvic high‐grade serous carcinomas.     

Endoscopic findings in upper gastrointestinal bleeding patients at Lacor hospital,northern Uganda

Background

Upper gastrointestinal bleeding (UGIB) is a common emergency medical condition that may require hospitalization and resuscitation, and results in high patient morbidity. Upper gastrointestinal endoscopy is the preferred investigative procedure for UGIB because of its accuracy, low rate of complication, and its potential for therapeutic interventions.

Objective

To determine the endoscopic findings in patients presenting with UGIB and its frequency among these patients according to gender and age in Lacor hospital, northern Uganda.

Methods

The study was carried out at Lacor hospital, located at northern part of Uganda. The record of 224 patients who underwent endoscopy for upper gastrointestinal bleeding over a period of 5 years between January 2006 and December 2010 were retrospectively analyzed.

Results

A total of 224 patients had endoscopy for UGIB which consisted of 113 (50.4%) males and 111 (49.6%) females, and the mean age was 42 years ± SD 15.88. The commonest cause of UGIB was esophagealvarices consisting of 40.6%, followed by esophagitis (14.7%), gastritis (12.6%) and peptic ulcer disease (duodenal and gastric ulcers) was 6.2%. The malignant conditions (gastric and esophageal cancers) contributed to 2.6%. Other less frequent causes of UGIB were hiatus hernia (1.8), duodenitis (0.9%), others-gastric polyp (0.4%). Normal endoscopic finding was 16.1% in patients who had UGIB

Conclusions

Esophageal varices are the commonest cause of upper gastrointestinal bleeding in this environment as compared to the west which is mainly peptic ulcer disease.     

Plasma vitamin C concentration in pregnant women with pre-eclampsia in Mulago hospital, Kampala, Uganda

Background

Oxidative stress plays a role in the aetiology of pre-eclampsia and vitamin C may prevent pre-eclampsia.

Objective

To determine the association between plasma vitamin C and pre-eclampsia in Mulago Hospital, Kampala, Uganda.

Methods

This case-control study was conducted at Mulago Hospital from 1^st May 2008 to 1^st May 2009; 207 women were the cases and 352 women were the controls. Plasma vitamin C was assayed in the women using a colorimetric method. An independent t test was used to find the difference in the means of plasma vitamin C and logistic regression was used to find the association between plasma vitamin C and pre-eclampsia.

Results

The mean plasma vitamin C was 1.7(SD=0.7) × 10³ µg/L in women with pre-eclampsia and 1.9(SD=0.7) × 10³ µg/L in women with normal pregnancy (P=0.005).Women with low plasma vitamin C were at an increased risk of pre-eclampsia (OR 2.91, 95% CI: 1.56–5.44).

Conclusion

There was a strong association between low plasma vitamin C, and pre-eclampsia in women attending antenatal clinics at Mulago Hospital, Kampala.Health workers need to advise women at risk in the antenatal period about diet, especially foods which are rich in vitamin C to probably reduce pre-eclampsia.     

Microbial aetiology and sensitivity of asymptomatic bacteriuria among ante-natal mothers in Mulago hospital, Uganda

Background

Asymptomatic bacteriuria in pregnancy is associated with potential urinary and obstetric complications. However the prevalence aetiology and antimicrobial sensitivity patterns of asymptomatic bacteriurea among women attending ante-natal care in our Hospital is not known.

Objective

To determine the prevalence and identify the aetiological agents associated with assymptomatic bacteriurea in antenatal mothers in Mulago Hospital. We also intented to determine the anti-microbial sensitivity patterns of the common uropathogen in this population

Methods

We performed culture and anti-microbial sensitivity tests on urine samples from 218 consecutive ante-natal mothers in Mulago Hospital. All participants did not have any clinical symptoms attributable to urinary tract infection.

Results

Twenty nine (13.3%) of the samples had significant bacterial growth and E.coli was the commonest isolate (51.2%). There was a high level (20–62%) of anti-bacterial resistance to the commonly used antibiotics.

Conclusion

Asymptomatic bacteriuria is common among ante-natal mothers in Mulago. E. Coli that is resistant to the most commonly used antibiotics is the commonest isolate.”     

Comparison of pelvic phased-array versus endorectal coil magnetic resonance imaging at 3 Tesla for local staging of prostate cancer

Purpose

Several studies have demonstrated the superiority of endorectal coil magnetic resonance imaging (MRI) over pelvic phased-array coil MRI at 1.5 Tesla for local staging of prostate cancer. However, few have studied which evaluation is more accurate at 3 Tesla MRI. In this study, we compared the accuracy of local staging of prostate cancer using pelvic phased-array coil or endorectal coil MRI at 3 Tesla.

Materials and Methods

Between January 2005 and May 2010, 151 patients underwent radical prostatectomy. All patients were evaluated with either pelvic phased-array coil or endorectal coil prostate MRI prior to surgery (63 endorectal coils and 88 pelvic phased-array coils). Tumor stage based on MRI was compared with pathologic stage. We calculated the specificity, sensitivity and accuracy of each group in the evaluation of extracapsular extension and seminal vesicle invasion.

Results

Both endorectal coil and pelvic phased-array coil MRI achieved high specificity, low sensitivity and moderate accuracy for the detection of extracapsular extension and seminal vesicle invasion. There were statistically no differences in specificity, sensitivity and accuracy between the two groups.

Conclusion

Overall staging accuracy, sensitivity and specificity were not significantly different between endorectal coil and pelvic phased-array coil MRI.     

The spectrum of liver diseases in HIV infected individuals at an HIV treatment clinic in Kampala, Uganda

Background

Liver diseases are common in patients with HIV due to viral hepatitis B and C co-infections, opportunistic infections or malignancies, antiretroviral drugs and drugs for opportunistic infections.

Objective

To describe the spectrum of liver diseases in HIV-infected patients attending an HIV clinic in Kampala, Uganda.

Method

Consecutive patients presenting with jaundice, right upper quadrant pain with fever or malaise, ascites and/or tender hepatomegaly were recruited and underwent investigations to evaluate the cause of their liver disease.

Results

Seventy-seven consecutive patients were recruited over an eleven month period. Of these, 23 (30%) had increased transaminases because of nevirapine (NVP) and/or isoniazid (INH) hepatotoxicity. Although 14 (61%) patients with drug-induced liver disease presented with jaundice, all recovered with drug discontinuation. Hepatitis B surface antigen was positive in 11 (15%) patients while anti-hepatitis C antibody was reactive in only 2 (3%). Probable granulomatous hepatitis due to tuberculosis was diagnosed in 7 (9%) patients and all responded to anti-TB therapy. Other diagnoses included alcoholic liver disease, AIDS cholangiopathy, hepatocellular carcinoma, schistosomiasis, haemangioma and hepatic adenoma. Twelve (16%) patients died during follow-up of which 7 (9%) died because of liver disease.

Conclusion

Drug history, liver enzyme studies, ultrasound, and hepatitis B and C investigations identified the probable etiology in 60 (78%) of 77 patients with HIV infection presenting with symptoms and/or signs of liver disease.     

Antenatal needs of couples following fertility treatment: a qualitative study in primary care

Background

It is known that couples may experience emotional distress while undergoing infertility treatment, but less is known about their experience of pregnancy following successful conception. Typically, couples are discharged from the fertility clinic to receive standard antenatal care. Recent research has raised questions about whether this care adequately meets their needs.

Aim

To explore the antenatal experiences of females and males who have successfully conceived through infertility treatment.

Design and setting

An exploratory qualitative approach was undertaken, using individual, in-depth interviews with females and males who had successfully undergone infertility treatment in one of three fertility clinics in the south of England.

Method

Twenty participants were interviewed (12 females and eight male partners) when their pregnancy had reached 28 weeks’ gestation. Participants were asked about their experiences of infertility treatment, pregnancy, and antenatal care. Interviews were audiorecorded, transcribed, and analysed thematically.

Results

Analysis of the interviews suggested females and males experienced a ‘gap’ in their care, in terms of time and intensity, when discharged from the fertility clinic to standard antenatal care. This gap, combined with their previous experience of infertility treatment, heightened their fear of pregnancy loss and increased their need for support from their health professionals. Participants’ previous experience of infertility treatment also appeared to deter them from preparing for the birth and parenthood, and disclosing negative feelings to others about the pregnancy.

Conclusion

Females and males who have successfully undergone infertility treatment may require additional support in primary care to address anxiety during pregnancy, enable disclosure of negative feelings, and to help them prepare for childbirth and parenthood.     

Outcomes and reasons for dacryocystorhinostomy (DCR) at KCMC, a Tanzanian referral hospital, 2001-2006

Background

External dacryocystorhinostomy (DCR) is a surgical intervention aimed to treat blocked nasolacrimal ducts of almost all causes. To date there is only limited data available from the Sub Saharan African setting.

Objectives

This study aimed to provide further information of the outcomes of DCR in Africa.

Methods

Records of all patients undergoing external DCR operations from January 2001 to April 2006 were systematically searched. 55 patients were identified and notes were available for 45 patients.

Results

Discharge and epiphora were resolved in 90.9% (30/33) and 84.4% (27/32) of patients respectively. Over half the cases (51.1%) were children. The commonest reason for operation was chronic dacryocystitis (51.1%). Outcomes for DCR were not significantly different for either children or adults and a clear improvement of symptoms was found in the vast majority of cases.

Conclusion

This study provides information on the outcomes of DCR in the African population. An 84.4% cure rate of epiphora and 90.9% cure rate of discharge is comparable with findings in other developing countries. This study supports the continued use of this intervention in skilled hands for treatment of blocked nasolacrimal duct.     

Pattern and outcome of childhood intestinal obstruction at a Tertiary Hospital in Nigeria

Background

Intestinal obstruction is a common cause of pediatric surgical emergency with a high morbidity and mortality in Africa.

Methods

A retrospective review of cases managed from January 1996 to December 2005 at a teaching hospital in Southwestern, Nigeria was done to examine the pattern of causes of intestinal obstruction in children and the management outcome.

Results

One hundred and thirty cases were seen over the study period with an age range of 2 hours to 14 years. Majority (61.24%) were infants, while 18.46% were neonates.Fifty-five cases (42.31%) were due to congenital causes while the rest were of acquired causes. The major causes of intestinal obstruction in the study were intussusception (29.23%), anorectal malformations (22.31%), obstructed inguinoscrotal hernia (16.92%) and Hirschsprung''s disease (13.85%). Surgical site infection and sepsis were the commonest complications observed with an overall complication rate of 60.78%. The mortality rate was 3.08% and most (75%) occurred in neonates.

Conclusion

While mortality as an outcome of management is low, the morbidity was very high in this study.     

Ocular manifestations in paediatric HIV/AIDS patients in Mulago Hospital,Uganda

Background

In Uganda the prevalence of HIV averages 12% as was reported to the STD/AIDS control surveillance unit. In Uganda there are approximately 30,000 HIV infected infants per year. The burden of HIV disease is high in Uganda and patients present with ocular complications. However, there is paucity of information and knowledge concerning ocular manifestations in the paediatric HIV/AIDS population and how they may differ from those of adults.

Objectives

To describe the ocular manifestations of HIV/AIDS infection in an African paediatric population. Generally the study will record the external ocular manifestations seen but specifically to document the intra-ocular lesions, in particular the retinal changes associated with paediatric HIV/AIDS.

Design

A cross-sectional hospital based study.

Setting

The study was conducted at the Paediatric Infectious Disease Clinic at Upper Mulago Hospital, in Kampala, Uganda.

Patients

Patients are those with positive HIV sero status, with or without symptoms and signs of AIDS.Parents/caretakers of the children were interviewed to obtain the socio-demographic data of the patients and a general physical as well as an ophthalmic examination were conducted to document any ocular problems.

Results

A total of 158 HIV -infected children were examined. The overall rate of ophthalmic involvement was 35%. The most common finding was a non-purulent conjuctivitis, observed in 12% of the patients, followed by perivasculitis of the peripheral retinal vessels, in 12 % of patients and molluscum contagiosum.
