Pulmonary involvement is an uncommon extraintestinal manifestation of salmonellosis. We describe a 30 year old man with mental retardation, presenting with salmonella gastroenteritis and bacteremia. An early pneumonia evolving in the clinical setting of severe kyphoscoliosis, suggests that hematogenous spread to the lungs may occur as a result of abnormalities of the chest wall.

Undetected foreign body aspiration is a well-known problem not only in children and patients with predisposing conditions like mental retardation, seizures or brain tumours, but also in healthy subjects. The clinical signs are quite different. Haemoptysis, cough, recurrent or chronic penumonia and bronchitis may occur. These symptoms are often accompanied by fever, weight loss and night sweat. Atelectasis, respiratory distress or death have been described. We demonstrate the case of a 39-year old man with Down syndrome who was transferred to our hospital because of pneumonia in the left lower lobe that had been lasting for about two months. It had been resistant to several antibiotic regimens. Computerised tomography led to the suspicion of a bronchial carcinoma with poststenotic infiltration of the lower lobe. Fibreoptic bronchoscopy and biopsy confirmed the diagnosis of a foreign body in the distal part of the left main bronchus. After two weeks of treatment with ciprofloxacin regression of the acute inflammation occurred. During a second bronchoscopy we could extract the foreign body (a 1 x 1.7 cm vertebra of a dove). It is concluded that undetected foreign body aspiration can occur in various clinical settings and fibreoptic bronchoscopy is a suitable approach providing an exact diagnosis.

Percutaneous endoscopic gastrostomy (PEG) has gained great popularity for children with malnutrition and eating disorders secondary to chronic illness. However, the procedure is not without risks. We report on 62 infants and children, median age 4 years (1 month-20 years), who underwent PEG placement. Cerebral palsy with or without mental retardation was the most common diagnosis (50%). No complications related to the PEG procedure itself occurred, but postoperative pneumonia was seen in 10%. Late complications were few: intraperitoneal migration of the button in one child and prolapse of the stoma in another. At the time of button placement, after median 14 weeks, mean weight had increased from a standard deviation score of -2.7 to -2.2 (P < 0.001). We consider PEG to be a safe procedure for children with malnutrition requiring enteral feeding. Due to potential risks and complications related to this method, a multidisciplinary approach, as found in a "nutritional support team", is recommended.

Primary varicella-zoster infection is very common during childhood and few patients develop complications. The most frequent complications are bacterial infection of the lesions, laryngitis and varicella pneumonia. In the nervous system it can produce encephalitis and especially cerebellitis. We describe a case of primary varicella-zoster induced rhabdomyolysis in a 5-year-old girl with mental retardation, microcephalia and mild diplegia who, in the context of varicella infection, presented extreme muscular weakness and prostration. Blood and urine tests showed high creatine phosphokinase concentrations and myoglobinuria. The patient received aggressive intravenous hydration. Evolution was favorable with no renal failure. Rhabdomyolysis can produce life-threatening complications such as renal failure, intravascular disseminated coagulation and hyperkaliemia. The disease can be precipitated by alcohol ingestion, compression injury and generalized seizures. Infectious etiology is less common. Few reports have been published on primary varicella-zoster induced rhabdomyolysis but, because creatine phosphokinase concentrations are not routinely performed in varicella infection, very mild cases might have been under-diagnosed. Despite its rarity, this disease should be considered in cases of infection, since early treatment with hyperhydration can prevent complications.

The efficacy and safety of topiramate in patients with intractable mixed seizures, mental retardation (MR), and developmental disabilities (DD) were investigated. Twenty patients (eight females and 12 males) aged 21-57 years old with intractable epilepsy with mixed seizures, MR [profound (five), severe (three), moderate (two), mild (eight) and borderline (two)], and DD were treated with adjunctive topiramate 25 mg per day for 1 week followed by titration to clinical response (range 50-350 mg per day). Other antiepileptic drugs (AEDs) were decreased simultaneously. Topiramate therapy was discontinued in four patients for adverse events consisting of disorientation, unsteadiness, and pneumonia (one patient); anaphylactic shock from a tuna fish allergy (one); patient choice (one); and loss to follow-up (one). Seizures improved by gt-or-equal, slanted 50% in 11 of 16 patients (69%). Two patients (13%) were seizure free, including one patient who prior to topiramate therapy was seizure free but experiencing an intolerable adverse effect during therapy with another AED. Seizure duration and/or severity decreased in seven patients (44%). An increase in alertness was observed in 11 patients (59%). Topiramate was associated with improvement in seizure severity and alertness in this series and may be useful as adjunctive therapy in patients with mixed seizures, MR, and DD.

In a retrospective review at a long-term care facility serving persons with mental retardation, I discovered a noteworthy difference in the frequency of pneumonia experienced by persons receiving nutrition via a surgically created jejunostomy as compared to a gastrostomy. Over a 24-month period, 25 people being fed via a gastrostomy tube experienced 40 cases of pneumonia during 508 person-months of observation, whereas 5 individuals being fed via a jejunostomy tube did not experience any cases of pneumonia during 96 person-months of observation. The enteral feeding access sites for these individuals were established at various times as long ago as 12 years prior to this review period. Selection of the specific access site for each individual was not randomized.

Human cytomegalovirus (HCMV) represents one of the most medically important human viruses and causes a wide spectrum of human diseases, including birth defects and mental retardation in newborns, common opportunistic infections in acquired immunodeficiency syndrome (AIDS) patients (e.g., CMV-associated retinitis and pneumonia), and possibly cardiovascular diseases such as atherosclerosis. This chapter describes the utilization of RNase P ribozyme-specifically, M1GS ribozyme, as a gene-targeting agent for blocking HCMV gene expression and growth. The target for the RNase P ribozyme is the overlapping region of the mRNAs that code for HCMV major transcription factors IE1 and IE2, which are essential for viral gene expression and replication. The methods described in this chapter focus primarily on i) construction of the retroviral vector for expression of M1GS ribozymes in cultured cells, ii) generation of stable cell lines expressing ribozymes, iii) determination of the expression of M1GS RNAs in human cells, and iv) evaluation of the efficacy of ribozymes in inhibiting HCMV IE1/IE2 expression and viral growth. Using these methods, we successfully constructed M1GS RNAs against the IE1/IE2 mRNA sequence and recently showed that a reduction of up to 150- to 3000-fold in HCMV growth is found in cells that express the ribozymes.

Cornelia De Lange syndrome is a relatively uncommon, multiple congenital anomaly / mental retardation disorder of unknown etiology. Its incidence has been reported to vary from 1 : 30,000 to 1 : 50,000 of live births, without any known racial predilection. However, it has been considered to be due to a new dominant mutation. Main clinical features of this syndrome include growth retardation, developmental delay, hirsutism, structural limb abnormalities, mental retardation and facial growth discrepancies. Main causes of death in such patients include pneumonia along with cardiac, respiratory and GI abnormalities.

A male child aged one and a half years with a history of rectal bleeding, on examination was found to have severe degree of anaemia with grade -III protein-energy-malnutrition and pneumonia. Colonoscopy revealed features of colonic polyposis. An upper gastro-intestinal endoscopy showed a duodenal polyp while barium meal follow-through did not reveal any polyps in the small intestine. Total colectomy and ileo-rectal anastomosis was done. Following histopathological study, the diagnosis of Juvenile polyposis syndrome was made, a very rare entity and is known to lead to adenocarcinoma of the gastrointestinal tract. In addition the child was found to have macrocephaly and mental retardation. The rarity and importance of the diagnosis of juvenile polyposis syndrome associated with macrocephaly and mental retardation (?Ruvalcava-Myhre-Smith syndrome) prompted the documentation of this case.

A 4-year-old Japanese boy, the youngest of three brothers, presented with ichthyosiform hyperkeratosis over his whole body, eczematous erythema with partial desquamation and erosion on the flexor side of the joints of extremities, the fossa axillaries, and the genital and buttock regions, and total hair loss on the scalp and the absence of eyebrows and eyelashes. In addition to the ichthyotic eruptions and hair abnormalities, he also had a ventricular septal defect, mental retardation, growth retardation, characteristic facial features such as a depressed nasal bridge, low-set ears, and ocular hypertelorism; therefore, he was diagnosed with cardio-facio-cutaneous (CFC) syndrome. The patient's family did not have a history of consanguineous marriage. The parents and the eldest son were healthy. However, the second son, also born with ichthyosiform hyperkeratosis over his whole body, total hair loss on the scalp, myocardial deficiency, mental retardation, growth retardation, and characteristic facial features, had died of pneumonia and sepsis at the age of 1.5 years. Because the middle brother had the same disease, the present case is considered to be a rare case of CFC syndrome with in a single generation.
