During an inquiry performed in Gaboon the prevalence of hydroceles had led to puncture systematically every vaginal flow. 68 fluids were so collected at the end of the inquiry. Subsequently the statistical analysis of the results in men seems to suggest a correlation between microfilaremia (Loa loa and D. perstans) and the prevalence of hydroceles. Microfilariae were found in 77% according to the following distribution: Loa loa seldom diagnosed in this kind of flow were detected in 10%; D. perstans although never reported so far in hydrocele fluids appeared to be present in 62%. O. volvulus more currently referred to in hydrocele liquids were scarcely traced.

Since the antivectorial control in 1948, the parasitological and clinical aspects of the onchocerciasis focus at Kinsuka/Kinshasa have not been studied further until now. The population examined was selected for its daily contact with the vector. It constituted 143 adults, including fishermen, stonebreakers and women cultivators, and 26 children aged from 10 to 16 years. People were subjected to an ophthalmological examination as well as to an investigation for Onchocerca volvulus microfilariae. Adults were examined for the presence of nodules as well as for dermal and lymphatic manifestations of onchocerciasis. The microfilaria carrier rate (MfCR) was 59.2%. The mean microfilaria density (MfD) was 9.7 mf mg-1. Only 20% of the adults presented with small onchocercal nodules. Cutaneous lesions were mild. Lymphatic complications such as adenolymphocele, hydrocele and elephantiasis of the lower limbs were observed in 18% of the adults. No one was blind from onchocerciasis, although nine patients of 60 years or over had lost the use of one eye. Punctate keratitis occurred commonly in young people. Ocular lesions, except for punctate keratitis, developed progressively after 55 years and they became worse with the degree of infection, age and length of stay. Hyperendemic and insufferable in 1940, onchocerciasis has become, in 1985, hypoendemic and no longer a public health problem. One could deduce that a situation similar to that in Kinsuka may occur within 30 years in other foci which are today hyperendemic and where prophylaxis has been started.

Twenty cases of meconium peritonitis were found between September 1980 and March 1988 at Mackay Memorial Hospital. The male to female ratio was 1.5 to 1. Six of the 20 cases involved premature babies. The great majority presented symptoms and signs before 5 days old, but one case was not diagnosed until 13 months of age. Polyhydramnios of the mother was found in six cases (30%). Abdominal distension was the universal symptom in all 20 cases. Hydrocele was noticed in 8 of the 12 male babies. In seven cases (35%) radiological examination showed abdominal calcifications. All patients underwent surgical intervention. Peritonitis was of cystic type in seven cases (35%); fibroadhesive in nine cases (45%); generalized in four cases (20%). Evident intestinal perforation was noted in 13 patients, and a mechanical obstructive lesion was found in 9 cases (45%) including intestinal diaphragm, atresia, volvulus, and Hirschsprung's disease. In only two patients (10%) was neither evident perforation nor obstructive lesion. The overall mortality rate was 30% (6/20), with no mortality after 1986 (0/6). The mortality seemed increased in those associated with perforation (4/13) and midgut volvulus (2/2) in particular, compared with non-perforation cases (1/7). It appears that early aggressive operation, and meticulous postoperative care, have contributed to the higher survival rate in recent years.

In a cross-sectional, epidemiological and parasitological study of human filariasis, 845 individuals were examined in settlements along the Igwun Basin, Imo State, Nigeria. Four different filarial nematode species were identified. Two hundred and fifty-six (30.3%) of the individuals examined were positive for Onchocerca volvulus, 113 (13.4%) for Mansonella perstans, 76 (9.6%) for Wuchereria bancrofti and 77 (9.1%) for Loa loa. Microfilarial rates increased with age of individuals and showed a tendency towards higher prevalence rates in males than in females. The intensity of O. volvulus infection was high, with the highest microfilarial density of 44 mf mg-1 snip which occurred in the 40-49-year-old individuals. In W. bancrofti and L. loa infections, infections of over 1000 mf 20 ml-1 blood were recorded in 15.8% and 19.5% of individuals, respectively. Observed clinical signs were associated with inflammatory, lympho-obstructive and ocular manifestations. In M. perstans infections all clinical cases were inflammatory. In W. bancrofti, 44.4% of clinical cases were inflammatory, and lympho-obstructive manifestations consisted of 23.8% chyluria, 12.7% hydrocele and 19.1% elephantiasis. In L. loa infections all clinical cases were inflammatory with indications of Calabar swellings. In O. volvulus infections 23.5% of clinical cases were inflammatory, while 76.5% showed ocular manifestations. The absence of blindness despite high O. volvulus infection rates was remarkable. The presence of potential insect vectors and the occurrence of clinical signs are indications of active transmissions.

Meconium periorchitis is uncommon. In the unborn child the peritoneum vaginal canal is open and, secondary to intestinal perforation due to any cause (intestinal atresia, volvulus, and others), meconium peritonitis occurs. The intestinal content reaches the scrotal vaginal cavity. Meconium peritonitis can heal spontaneously and without consequences. Calcified remnants of this event may remain in the peritoneal cavity and/or scrotum. In the newborn, a hydrocele and scrotal mass can be observed; the ultrasound will show a heterogeneous image with calcifications. Meconium periorchitis or meconium vaginalitis resolves spontaneously. The lack of awareness of this disease could lead to unnecessary surgery in the newborn. We present a 33 days old patient with a scrotal mass in whom surgery was performed with the pathological diagnosis of meconium periorchitis.
