Congenital nephrotic syndrome, an uncommon presentation of cytomegalovirus infection

Cytomegalovirus (CMV) infection is a very rare infection in children as well as in infancy. In CMV infection extra renal manifestations in central nervous system (CNS), eyes and hematological are prominent and common than renal manifestation. We are describing two case reports one at the age of 5 months and another at one month with features of both extra renal and renal manifestations of nephritic syndrome. Our first case presented with predominant features of CNS manifestations like convulsion and spastic monoplegia, sensory type of deafness and absence of light reflexes along with nephritic features. Deafness and absence of light reflex were confirmed by audiometric and ophthalmological examination and brain atrophy was confirmed by CT scan. Our second case had features of hypothyroidism along with nephritic features. Hypothyroid status was confirmed by elevated serum TSH level and reduced T4 level. In both cases nephritic features were confirmed at bed site urine examination by heat coagulation test and other relevant investigations. CMV infection was confirmed in both cases by detecting anti CMV IgM by ELISA method. Both patients were clinically improved with intravenous gangcyclovir therapy. In these two cases reports, clinical, serological and therapeutic observation established the causal relationship between the CMV infection and nephrotic syndrome.     

Seroprevalence of human parvovirus B19 infection in an urban population in Malaysia

A seroepidemiological study carried out on 800 stored serum samples collected between January 1999 to December 2000 derived from an urban population in Malaysia showed that the overall seropositive rate of human paravovirus B19 infection was 37.6%, with an overall geometric mean titre (GMT) of 18.3 IU. The seropositive rates of B19 among the male and female populations were 39.0% and 36.3% respectively. The seropositive rates among the racial groups were 37.2%, 38.2%, 38.1% and 29.4% respectively for the Malays, Chinese, Indians and other races. There was no statistical significant gender and racial differences in the B19 seropositive rates. When compared with the seroprevalence of B19 infection in other Asian countries, the seropositive rate of B19 in Malaysia was low in the younger age group and increased steadily with age. The unusual finding in this study was the presence of a high seropositive rate in those between six months to five years of age, especially in children in the one year old age group.     

Backcalculation of HIV infection rates in Malaysia

It has been almost two decades ago since the first AIDS case was reported in Malaysia. It has also been approximately eight years ago when the method of backcalculation was used to estimate the past HIV infection rate from the AIDS incidence data and an estimate of the incubation period distribution. This method is used because it makes use of the Malaysian AIDS incidence which is fairly reliable and reflects the trend of the epidemic as compared to the HIV infection rate recorded. The latest results generated show a slowdown in the increase of the number of estimated infected HIV+ cases in the late 1990s and this trend is supported by a slowdown in the increase of the number of AIDS cases recorded.     

Neurocysticercosis: an under-recognized cause of neurological problems

Neurocysticercosis is an uncommon, and under-recognized condition in Australia. Changes in immigration patterns may lead to a rising prevalence in this country. Epilepsy is the most common presentation, but it has many other variable forms of neurological manifestations. Eight cases are described, all in immigrants from Eastern Europe, Asia or Central America; the disease was presumably acquired before arrival in Australia. Six patients had symptoms for two to 30 years before the diagnosis was made and, in some cases, the first neurological manifestations appeared decades after initial infection. In patients with active disease a successful outcome followed therapy with praziquantel and corticosteroids. We advise that all patients requiring treatment be admitted to hospital for corticosteroid and anticonvulsant therapy to minimize the clinical deterioration which may result from therapeutic destruction of larvae.     

Fulminant infection by uncommon organisms in animal bite wounds

In 1995 and 1996, 215 patients exposed to different species of animals were treated at the Amarnath Polyclinic, Balasore, in India. Among them were two children infected by uncommon organisms, i.e., Capnocytophaga canimorsus and Pasteurella multocida; the patients recovered with appropriate antibiotic therapy.     

Prevalence of hepatitis delta virus infection in Malaysia

The prevalence of coinfection, superinfection and chronic infection with the hepatitis delta virus (HDV) was studied in 324 hepatitis B surface antigen (HBsAg)-positive Malaysians. Of these, 10.0% (5/50) had coinfection, 5.7% (11/194) had superinfection, but none of the 80 patients with chronic liver disease (CLD) or primary hepatocellular carcinoma (PHC) had chronic infection with HDV. The overall HDV infection was 4.9% (16/324). One of the coinfection cases acquired the HDV infection as early as 1982. HDV superinfection was detected mainly among IV drug abusers (20% or 7/35) and promiscuous males and females (13.6% or 3/22). They were all asymptomatic. Only 0.8% (1/125) apparently healthy blood donors was infected with HDV. None of the 12 multi-transfused patients examined were positive. Malaysia is the only Southeast Asian country examined so far in which HDV infection was detected. The reason could be that the IV drug abusers and the sexually promiscuous groups missed being examined in the other countries. Comparing the HDV infection rates in 4 categories of infected Malaysians (viz. acute hepatitis B patients, IV drug abusers, blood donors and CLD patients) with those of other countries, it was noted that the Malaysian rates were similar to the lowest in the range of prevalence rates of each category in the latter group. The rate of coinfection in a preliminary study in 1982-84 (9.0% or 1/11) was not very different from that obtained to date (10.0% or 5/50).(ABSTRACT TRUNCATED AT 250 WORDS)     

Perioral dermatitis: an uncommon condition?

To document the persistence of perioral dermatitis at dermatology clinics at University Hospital, Saskatoon, we reviewed the charts of all patients with the condition seen between January 1983 and March 1985. Patients with rosacea referred to the clinics during the same period were used as a comparison group. A total of 80 patients with perioral dermatitis and 117 patients with rosacea were seen during the study period; most were female. Those with perioral dermatitis were significantly younger and had a significantly shorter mean duration of the eruption before presentation than those with rosacea (p less than 0.001). The distribution of the lesions was different in the two groups. Sixty-eight (85%) of the patients with perioral dermatitis and 45 (38%) of those with rosacea had used topical corticosteroids, a postulated risk factor for perioral dermatitis; the use of potent topical corticosteroids was frequent in both groups. Despite continuing medical education on the dangers of chronic use of these agents for eruptions on the face, physicians continue to prescribe them.     

Chronic Caffey's disease: an uncommon entity in children

Chronic Caffey's disease in an uncommon condition in children is characterized by an acute inflammatory reaction in the periosteum along with systemic disturbances. A 30 months old boy was reported in the pediatric unit of BSMMU, Dhaka about two and half years back with the complaints of multiple painful soft tissue swelling in different parts of the body since birth and delay in growth and development. The child was found well and alert, moderately pale, febrile with hard, tender swelling of mandible on both sides. There were multiple swellings over the right arm, forearm, both thighs and bowing of the lower limbes. Investigations revealed normal serum calcium and phosphate level with mild elevation of alkaline phosphatase. Radiological findings showed periosteal new bone formation in mandible and long bones. There was diaphyseal expansion of the long bones with expansion of the ribs anteriorly. He was diagnosed as a case of chronic caffey's disease on the basis of history, clinical examination and investigation.     

Aortobronchial fistula: an uncommon cause of haemoptysis

A 16 year old patient who presented with haemoptysis as the main manifestation of the infection of an aortic patch graft is reported. The importance of being alert about the possibility of an aortobronchial fistula in patients with haemoptysis who have been previously subjected to cardiovascular surgery is emphasized.     

An uncommon cause of recurrent falls in an elderly man

Falls are common among the elderly population. Examinations for the cause of falls are usually mundane, but may be challenging, leading to surprising diagnoses. We report on a previously healthy elderly man who presented with repeated falls and rapidly progressive limitations in mobility, in addition to a stutter. Neuroimaging was particularly helpful for making the diagnosis in this patient.     

Coeliac artery thrombosis: an uncommon cause of an acute abdomen

Coeliac artery thrombosis with ischaemia is a rare condition, which usually presents with severe peptic ulcer disease symptoms. It is usually associated with risk factors for thrombosis or embolism. The manifestation is rare because of large number of collaterals between the coeliac and superior mesentery artery. Early detection and intervention is required to prevent the progression of its complications that includes gastric ischaemic necrosis.     

Risk factors and outcomes of imipenem-resistant Acinetobacter bloodstream infection in North-eastern Malaysia

Objective

To determine the risk factors and outcomes of imipenem-resistant Acinetobacter baumannii (IRAB) bloodstream infection (BSI) cases, since there is very little publication on Acinetobacter baumannii infections from Malaysia.

Methods

A cross sectional study of 41 cases (73.2%) of imipenem-sensitive Acinetobacter baumanii (ISAB) and 15 cases (26.8%) of IRAB was conducted in a teaching hospital which was located at North-Eastern state of Malaysia.

Results

There was no independent risk factor for IRAB BSI identified but IRAB BSI was significantly associated with longer bacteraemic days [OR 1.23 (95% CI 1.01, 1.50)]. Although prior use of carbepenems and cephalosporin were higher among IRAB than ISAB group, statistically they were not significant. There was no significant difference in term of outcomes between the two groups.

Conclusions

Although statistically not significant, this analysis compliments previous publication highlighting the importance of appropriate empiric antibiotic usage in hospital especially carbepenems and need further evaluation with bigger subjects.
