Management of Ingested Foreign Bodies in Childhood

A total of 660 patients with ingested foreign bodies admitted to the general surgical services in two children''s hospitals in Liverpool are reviewed. Endoscopic removal (205 cases) is recommended for all foreign objects impacted in the oesophagus, with the exception of rounded or blunt objects in the lower third, which should be observed for a maximum of 12 hours. The indications for laparotomy for removal of a foreign body (43 cases, 6·5%) are the danger of perforation and failure of progression. The ingestion of a long slender object—for example a hair-grip—in a child under 2 years of age, is an absolute indication for prophylactic operative removal owing to the high incidence of impaction and perforation of the duodenum.     

Flexible Bronchoscopy with Multiple Modalities for Foreign Body Removal in Adults

Objectives

Aspiration of the lower airways due to foreign body is rare in adults. This study aimed to determine the outcome of patients who received flexible bronchoscopy with different modalities for foreign body removal in the lower airways.

Patients and Methods

Between January 2003 and January 2014, 94 patients diagnosed with foreign body in the lower airways underwent flexible bronchoscopy with different modalities, which included forceps, loop, basket, knife, electromagnet, and cryotherapy. The clinical presentation, foreign body location and characteristics, and applications of flexible bronchoscopy were analyzed.

Results

Forty (43%) patients had acute aspiration, which developed within one week of foreign body entry and 54 (57%) had chronic aspiration. The most common foreign bodies were teeth or bone. More patients with chronic aspiration than those with acute aspiration were referred from the out-patient clinic (48% vs. 28%), but more patients with acute aspiration were referred from the emergency room (35% vs. 6%) and intensive care unit (18% vs. 2%). Flexible bronchoscopy with different modalities was used to remove the foreign bodies (85/94, 90%). Electromagnet or cryotherapy was used in nine patients to eliminate the surrounding granulation tissue before foreign body removal. In the nine patients with failed flexible bronchoscopy, eight underwent rigid bronchoscopy instead and one had right lower lung lobectomy for lung abscess.

Conclusions

Flexible bronchoscopy with multiple modalities is effective for diagnosing and removing foreign bodies in the lower respiratory airways in adults, with a high success rate (90%) and no difference between acute and chronic aspirations.     

Removal of esophageal foreign bodies with a Foley balloon catheter under fluoroscopic control.

Between 1982 and 1985 removal of a nonorganic, smooth, radiopaque foreign body in the esophagus with a Foley balloon catheter under fluoroscopic control without sedation was attempted in 38 children. An ultra-low-dose fluoroscopic unit was used. In 35 children the foreign body (a coin) was either easily removed (in 29 cases) or advanced into the stomach (in 6). No complications of the procedure were observed. In three children the foreign body could not be removed by this means; it was subsequently removed by endoscopy (in two cases, both of coins) or esophagotomy (in two cases, both of coins) or esophagotomy (in one, of a stone). When carefully performed, removal of blunt, recently ingested esophageal foreign bodies with a Foley catheter under fluoroscopic control is a safe mode of treatment.     

Ultrasonography and computed tomography in the detection of overlooked gauze surgical dressings]

USI and CT were performed in 14 patients with textile foreign bodies left in the abdominal cavity and retroperitoneal space during operation on the biliary tracts (6 cases), kidneys (4 cases), pancreas (2), stomach (1), and during appendectomy (1). A decisive sign in USI that enabled one to detect gauze foreign bodies, was a stable echogenic zone corresponding to a proximal body contour with a solid acoustic shadow behind. Extra-organic localization of these changes contributed to making diagnosis. A certain amount of fluid could be seen around a foreign body during an exudative reaction. In CT, diagnosis was based on the detection of a formation with a capsule containing calcinates and air masses.     

Pneumococcal bacteraemia: 325 episodes diagnosed at St Thomas's Hospital.

Three hundred and twenty five episodes of pneumococcal bacteraemia occurred at St Thomas''s Hospital during 1970-84, accounting for 13.3% of all episodes of bacteraemia. Twice as many cases occurred in male as in female patients, and common predisposing factors included chronic chest disease, alcoholism, haematological malignancies, cirrhosis, and sickle cell anaemia. Mortality was 28.6% overall but only 11.8% among patients who received antibiotic treatment for at least 24 hours. Most patients (261) had pneumonia, 26 had meningitis, and eight were children with occult bacteraemia. The commonest serotype of pneumococcus in adults was type 3 (39 episodes), and these strains were associated with a high mortality. Other factors determining a fatal outcome included underlying disease (such as cirrhosis, malignancy, and chronic chest disease) and extrapulmonary infection. Almost half the survivors were treated for 10 days or less and became afebrile within 48 hours.     

Swallowed foreign bodies

Of 98 swallowed foreign bodies demonstrated, 71 with fate definitely known are reported. Seventeen of 20 foreign bodies in the esophagus had esophagoscopic removal. Only two of 51 foreign bodies in the gastrointestinal tract had laparotomy, while 49 were spontaneously passed. Early esophagoscopic removal of foreign bodies lodged in the esophagus and conservative management of foreign bodies which have passed the esophagogastric junction are recommended. Laparotomy is rarely indicated in the management of swallowed foreign bodies, although various observers are not in full agreement as to the circumstances in which "watchful waiting" is advisable nor as to how long it is permissible to wait for spontaneous passage. In 20 of 71 cases of swallowed foreign bodies, the objects were in the esophagus at the time the patient was first examined. Esophagoscopic removal was carried out in 17 cases. In two cases a foreign body was passed per rectum and in one was vomited. Laparotomy for removal was done in only two of the 51 cases in which the foreign body was already in the stomach or bowel at the time of examination, and in one of them the operation probably could have been avoided.     

Royal College of Physicians and Surgeons of Canada: annual meeting draws over 2000 physicians

In a review of 19 years'' experience with inhalation of foreign bodies by children the 33 patients (mean age 28 months) were found to have presented most frequently with wheezing or coughing, or both, of recent onset, and to have decreased air entry, rhonchi or respiratory stridor, or a combination of these signs. Eighteen children had inhaled a nut, a pea or a bean. The other 15 had inhaled various organic and inorganic objects. All the children underwent bronchoscopy, and the foreign body was completely removed in 19 during the first procedure; the remainder required repeated bronchoscopy or direct surgical removal of the foreign body, or both. Permanent disability or death was not encountered. The findingsof the study indicate that early bronchoscopic removal is the preferred treatment when a child inhales a foreign body.     

Severe infections caused by Propionibacterium acnes: an underestimated pathogen in late postoperative infections.

Propionibacterium acnes belongs to the cutaneous flora of humans and is rarely considered a pathogen in human diseases. It is a frequent contaminant in blood cultures; however, in some patients it has been identified as the causative agent of life-threatening infections. Within the last years we have observed an abrupt increase in severe P. acnes infections which prompted us to study in detail the clinical and microbiological features, risk factors, and outcomes of these cases. In a retrospective review of microbiological records of 905 Propionibacterium isolates from a five-year period (1990-95), 70 were identified from 20 patients with clinical and microbiological evidence of a P. acnes infection. The clinical syndromes included endocarditis (7 patients), post-craniotomy infections (6 patients), arthritis and spondylodiscitis (4 patients), endophthalmitis (2 patients) and pansinusitis (1 patient). The predominant predisposing conditions were previous surgery preceding the infection from 2 weeks to 4 years and implantation of foreign bodies such as prosthetic heart valves, intraocular lenses and ventriculo-peritoneal shunts. Therapy consisted of intravenous antibiotics in all cases and surgical procedures to remove infected tissue in eighteen patients. The outcome was favorable in sixteen patients (80 percent) who had a complete recovery. These data confirm the pathogenic potential of P. acnes in late post-surgical infections, in particular after implantation of a foreign body, and suggest a combined therapeutic approach with intravenous antibiotics and surgical removal of the infected tissue.     

Tinea capitis in adults in southern Spain. A 17-year epidemiological study

BackgroundTinea capitis is an infection of the hair due to keratinophilic fungi, known as dermatophytes. Although the disease is common in children, several studies have also shown that it is far from unusual in adults, especially in post-menopausal women and immunocompromised persons.AimsTo determine the incidence of tinea capitis in adults in our area, as well as the predisposing factors (gender, immunity), and causative species.Materials and methodsA retrospective study was conducted over a period of 17 years, from 1995 to 2011, collecting data on cases of tinea capitis diagnosed in our dermatology department. Information collected for all patients included age, gender, location of the lesions, results of direct examination and culture, immune status, cause of immunosuppression, and the prescribed treatment.ResultsThirty-three cases (11.4%) out of 289 cases of tinea capitis occurred in adults. Most of these adults (72%) were immunocompetent, and the rest were immunocompromised for different reasons. Three of the patients were men and 30 women, with 70% of the latter being post-menopausal. Trichophyton species were isolated in 76% of these adult patients, with Trichophyton violaceum being the most common. Treatment with oral terbinafine was successful in all these cases. Microsporum species were responsible for the other cases, all treated successfully with oral griseofulvin.ConclusionsThis series of tinea capitis in adults is one of the largest to date. It shows that tinea capitis is not uncommon among the immunocompetent adult population. In our geographical area, except for prepubescent patients, most cases affecting the adult population were caused by species of the genus Trichophyton. In these cases the treatment of choice was oral terbinafine, which considerably shortened the treatment time, and was associated with fewer side effects than the classical griseofulvin.

Coin ingestion,an unexpected finding at colonoscopy: case report

Gastrointestinal tract ingested foreign bodies are common problems, particularly in children. The most common ingested foreign bodies are coins. Once foreign bodies have passed through the esophagus and into the stomach, 80% will pass through the gastrointestinal tract unimpeded, with the remainder requiring endoscopic or surgical removal. It is rare to find ingested foreign bodies at routine colonoscopic examination, in particular in an adult without any prior history of ingestion.     

Common polymorphism (81Val>Ile) and rare mutations (257Arg>Ser and 335Ile>Ser) of the MC3R gene in obese Polish children and adolescents

The predisposing role to human obesity of the MC3R gene polymorphism is controversial. In this report we present the first study focused on the search for the MC3R polymorphism in the Polish population. Altogether 257 obese children and adolescents (RBMI>120) and 94 adults, who were never obese or overweight (BMI<25), were studied. For all subjects the entire coding sequence was analyzed by direct DNA sequencing. One common polymorphism (81Val>Ile) and two rare mutations (257Arg>Ser and 335Ile>Ser) were identified. The common polymorphism was widely distributed in the obese and control cohorts, while the mutations were identified in four obese subjects only. In case of the 335Ile>Ser substitution a three-generation family, consisting of 20 members, was also analyzed. It was found that all carriers of the 335Ser mutation were obese, but among non-carriers obese subjects also were found. Our study suggests that the predisposing effect to obesity of the 81Ile polymorphic variant is rather unlikely. With regard to the studied rare mutations we suggest that the 335Ser allele may have a small predisposing effect.     

Trends in Campylobacter pylori in pediatric and adult antral biopsies. A 5-year retrospective analysis.

Campylobacter pylori has been associated with chronic gastritis and antral ulceration in adults and has recently been reported in children with primary antral gastritis and duodenal ulceration. We reviewed all gastric antral biopsy specimens from children (n = 30) and adults (n = 77) over the past 5 years at the University of California, San Francisco. Tissue sections were stained with Giemsa to detect C pylori, and medical histories were obtained by chart review. The prevalence of C pylori in antral biopsy specimens with gastritis increased from 22% during the period 1983 to 1986 to 66% in 1987 (P less than .001). In all specimens showing gastritis, C pylori appeared more frequently in adults (31/67 [46%]) than in children (4/17 [24%]). In cases with primary gastritis, however, the prevalence of C pylori reversed to 57% (4/7) in children versus 49% (31/63) in adults. Most children (10/13) with gastritis and no C pylori had predisposing conditions. Infection with this organism was associated with more active inflammatory changes in adults than in children, but it may contribute to most cases of hitherto-unexplained gastritis in children. Further studies are needed to determine whether the prevalence of C pylori is increasing.     

Epidemiology of candidemia in Spain - Multicenter study

The results of the epidemiological study on candidemias with the highest number of cases carried out in Spain is presented. This study is included in the Epidemiological Survey of Candidemia in Europe supported by the ECMM in which another five countries take part. In the Spanish study, 19 hospitals participated, 290 candidemia episodes were analysed (80 in children under 15 years and 210 in adults), 293 strains of yeasts being isolated. Both in children and in adults, the risks factors more frequently observed were the intravenous catheter and previous antibiotic therapy. In adults, the most habitual underlying disease was the solid tumor and, in children, hematological diseases. Candida albicans was the most prevalent species isolated in adults (46.1%) and Candida parapsilosis in children (50%). As part of the therapy, the intravenous line was removed and antifungal treatment was prescribed to 74% and 92.5% of children, respectively and to 43.8% and 73.8% of adults. The antifungal agent of election in adults was fluconazole (54.8%) and liposomal amphotericin B (58.1%) in children. The global mortality of the study was 38.9%, which for ages was major in adults (41.4%) than in children (38.7%). The geographical distribution of the isolated species was homogeneous, C. albicans being the predominant species, with the exception of Galicia and Extremadura where C. parapsilosis was the most frequent.     

Lanthanum-Induced Mucosal Alterations in the Stomach (Lanthanum Gastropathy): a Comparative Study Using an Animal Model

Lanthanum (La) carbonate (LC) is one of the most potent phosphate binders that prevents the elevation of serum phosphate levels in patients with end-stage renal diseases undergoing dialysis. LC binds strongly to dietary phosphate and forms insoluble complexes that pass through the gastrointestinal tract. La deposition in patients treated with LC is a recently documented finding particularly observed in gastric mucosa. We herein describe the detailed gastric mucosal lesions in 45 LC-treated patients and address the potential underlying pathologic mechanism using oral LC administration in rats. Microscopically, La deposition, as shown by subepithelial collections of plump eosinophilic histiocytes or small foreign body granulomas containing coarse granular or amorphous inclusion bodies, was found in the gastric mucosa of 44 (97.8%) of the 45 dialysis patients in the study cohort, which was most frequently associated with foveolar hyperplasia (37.8%). Using oral administration of rats with 1000 mg/day LC for 2 or more weeks, La deposition was consistently detectable in the gastric mucosa but not in other organs examined. In addition, various histologic alterations such as glandular atrophy, stromal fibrosis, proliferation of mucous neck cells, intestinal metaplasia, squamous cell papilloma, erosion, and ulcer were demonstrated in the rat model. Thus, orally administered LC can induce mucosal injury, designated here as La gastropathy, which may alter the local environment and result in La deposition in the gastric mucosa, thereby potentially inducing abnormal cell proliferation or neoplastic lesions.     

Candidemia at selected Canadian sites: results from the Fungal Disease Registry, 1992-1994

BACKGROUND: Candida species are important bloodstream pathogens that are being isolated with increasing frequency. Despite the availability of effective antifungal therapy, the mortality rate associated with Candida infection remains high. With the objective of describing the epidemiology of candidemia, the Canadian Infectious Disease Society conducted a study of candidemia in Canada. METHODS: Fourteen medical centres across Canada identified all patients with candidemia from March 1992 to February 1994 through blood culture surveillance for Candida spp. Patient-related data for invasive fungal infection were compiled retrospectively by chart review using a standardized data-recording form developed for the Fungal Disease Registry of the Canadian Infectious Disease Society. Cases of Candidemia were studied in relation to underlying medical conditions, predisposing factors, concurrent infection, antimicrobial agents, antifungal treatment and deaths. RESULTS: In total, 415 cases of candidemia were identified, 48 (11.6%) in children and 367 (88.4%) in adults. The causative pathogens were C. albicans in 286 cases (68.9%), C. parapsilosis in 43 (10.4%), C. glabrata in 34 (8.2%), C. tropicalis in 27 (6.5%) and other Candida species in 18 (4.3%); polymicrobial candidemia occurred in 7 cases (1.7%). The overall mortality rate was 46%, and the rate of deaths clinically related to candidemia was 19%. However, only 13 (27%) of the children died. A univariate analysis indicated that significant risk factors for death were age greater than 60 years, therapy for concomitant bacterial infection, stay in an intensive care unit, concurrent malignant disease, cytotoxic chemotherapy and granulocytopenia, although only age and stay in an intensive care unit emerged as significant risk factors in the multivariate analysis. After adjustment for other predictors of death, only infection with C. parapsilosis was associated with a lower mortality rate than infection with C. albicans. Treatment was given in 352 (84.8%) of cases. Amphotericin B was the preferred agent in 244 cases (69.3% of those treated); fluconazole was used in 101 cases (28.7%) and ketoconazole in 5 cases (1.4%). INTERPRETATION: Candidemia in Canada is caused predominantly by C. albicans. The mortality rate associated with candidemia is high, but it varies with the species of Candida and is lower in children than in adults. Age greater than 60 years and stay in an intensive care unit were the most significant risk factors for overall mortality.     

An update on the current epidemiological status of metastatic neoplasms to the thyroid

Secondary tumours to the thyroid gland are uncommon with an overall prevalence of 5.9% in autopsy studies. In recent clinical series, secondary thyroid cancer is seen in only 1.9% of malignant thyroids. There is no gender predominance both overall (female to male 1.07:1) and when stratified by common histological subtypes (renal cell carcinoma, lung adenocarcinoma and colorectal adenocarcinoma). The median age of patients diagnosed with metastatic thyroid tumours in major studies ranges from 54 to 68 years. Metastases are more frequent in patients with pre-existing or concurrent thyroid pathology. In autopsy studies, the most common primary sites are breast carcinoma and lung carcinoma. Renal cell carcinoma, lung carcinoma and breast carcinoma predominate in clinical series. Upper aerodigestive tract primaries often directly infiltrate the thyroid gland. The underlying frequency of a histological subtype, geographic prevalence and aggressiveness of primary cancer likely contributes to the incidence of metastasis in the thyroid gland. This is seen in case series from Asia where gastric and oesophageal primary cancers predominate. Secondary thyroid cancer can present metachronously (60%), synchronously (34%), or as the first presentation of the underlying cancer (6%). Late metastases and first clinical presentations of disease often originate from renal cell carcinomas while synchronous cases tend to originate from the lungs. Other common primary sites for first presentation of secondary thyroid cancer include the lung and oesophagus. Although rare, secondary thyroid cancer should be considered as a differential particularly in patients with previous malignancy, such as from the kidney, lung, or breast.

Cryptococcosis in Colombian children and literature review

Cryptococcosis is reported in adults and is often acquired immune deficiency syndrome (AIDS)-associated; however, its frequency in children is low. Based on the National Survey on Cryptococcosis conducted in Colombia, an epidemiological and clinical analysis was performed on cases of the disease observed in children less than 16 years old between 1993-2010. We found 41 affected children (2.6% prevalence) from the 1,578 surveys received. The country mean annual incidence rate was 0.017 cases/100,000 children under 16 years, while in Norte de Santander the incidence rate was 0.122 cases/100,000 (p < 0.0001). The average age of infected children was 8.4 and 58.5% were male. In 46.3% of cases, a risk factor was not identified, while 24.4% had AIDS. The most frequent clinical manifestations were headache (78.1%), fever (68.8%), nausea and vomiting (65.6%), confusion (50%) and meningeal signs (37.5%). Meningitis was the most frequent clinical presentation (87.8%). Amphotericin B was given to 93.5% of patients as an initial treatment. Positive microbiological identification was accomplished by India ink (94.7%), latex in cerebrospinal fluid (100%) and culture (89.5%). Out of 34 isolates studied, Cryptococcus neoformans var. grubii (VNI 85.3%, VNII 8.8%) was isolated in 94.1% of cases and Cryptococcus gattii (VGII) was isolated in 5.9% of cases. These data are complemented by a literature review, which overall suggests that cryptococcosis in children is an unusual event worldwide.
