Recurrent respiratory papillomatosis causing chronic stridor and delayed speech in an 18-month-old boy

Recurrent respiratory papillomatosis is a relatively uncommon disease that presents clinically with symptoms ranging from hoarseness to severe dyspnea. Human papilloma virus types 6 and 11 are important in the etiology of papillomas and are most probably transmitted from mother to child during birth. Although spontaneous remission is frequent, pulmonary spread and/or malignant transformation resulting in death has been reported. CO2 laser evaporation of papillomas and adjuvant drug therapy using lymphoblastoid interferon-alpha are the most common treatments. However, several other treatments have been tried, with varying success. In the present report, a case of laryngeal papillomatosis presenting with chronic stridor and delayed speech is described.

Unique expression of human papilloma virus type 5 and type 16 in esophageal squamous cell carcinoma-a case report

The role of human papilloma virus (HPV) in esophageal cancers from the low-incidence area (Western population) is unclear. We report a case of esophageal squamous papillomatosis associated with underlying esophageal squamous cell carcinoma (OSCC). The esophagectomy specimen confirmed presence of HPV-5 and HPV-16 suggesting a viral etiology. The significance of this dual infection is not known, but it suggests that esophageal papillomatosis is premalignant and should receive regular endoscopic follow-up. This is the first report of both HPV-5 and HPV-16 DNA detected in an esophageal cancer occurring in the Western population.

Juvenile laryngeal papillomatosis

Always ask about hoarseness and quality of voice in a history of any child presenting with cough or asthma-like symptoms. Children presenting with what appears to be an acute onset of hoarseness, without any physical signs of airways obstruction, should be reviewed after two weeks. If there is chronic hoarseness, referral to an ENT specialist should be considered with a view to laryngoscopy. If the child develops clinical signs of acute airway obstruction such as stridor or respiratory distress, prompt paediatric review is indicated. When referring, it is important to emphasise whether or not there is chronic hoarseness in order to differentiate the diagnosis from croup. Juvenile Laryngeal Papillomatosis may present with cough, pneumonia, dysphagia, or stridor, as well as hoarseness. These patients are often misdiagnosed as having asthma or allergies.

Prevalence of oral lesions in HIV patients related to CD4 cell count and viral load in a Venezuelan population

AIM

To determine the prevalence of oral lesions in a HIV+ group of patients, related to CD4 cell count and viral load in a Venezuelan population.

MATERIALS AND METHODS

In the present study, we evaluated 75 HIV+ adult patients, attended at the Center of Infectious Diseases, at the Faculty of Dentistry, Central University of Venezuela. Each patient was clinically examined for detection of oral mucosal lesions. In addition, CD4 cell count was determined by flow cytometry, as well as viral load by RT-PCR (Amplicor HIV-RNA, TM test 1.5, Roche).

RESULTS

85% (64/75) of HIV/AIDS patients showed associated HIV lesions. Oral Candidiasis constituted the most common lesion representing a 61% (39/64), followed by Oral Hairy Leukoplakia 53% (34/64); Oral Leukoplakia 34% (22/64), Melanic Hyperpigmentation 38% (18/64); Papilloma 13 (6/64), Lineal Gingival Erythema 8% (5/64); Aphtous Recurrent Stomatitis 5% (4/64) and Kaposi's Sarcoma 5% (3/64). Only one case of the following lesions were represented by Non Hodgkin Lymphoma, Multifocal Epithelial Hyperplasia, Recurrent Herpes, Histoplasmosis and Molluscum Contagiosum. The patients with a viral load of 30.000 copies/mm3 exhibited oral lesions related with HIV, independent of CD4 cell count, although patients with CD4+ levels of 200 cel/mm3 were more susceptible to develop these lesions.

CONCLUSIONS

The most common oral lesion was Oral Candidiasis followed by Oral Hairy Leukoplakia, Oral Leukoplakia and Melanic Hyperpigmentation. A high viral load was strongly associated to the oral lesions occurrence independently of CD4+ cell count.

Teat disorders predispose ewes to clinical mastitis after challenge with Mannheimia haemolytica

In order to study the effects of sheep teat disorders on the protection of the mammary gland, we used a Mannheimia haemolytica isolate, which did not cause clinical mastitis when deposited into intact teats. In the first experiment, this was deposited into the duct of teats with orf (Group A, n=5) or papilloma (Group B, n=3). In the second, teats were chapped and then, the organism was deposited into the duct (Group C, n=7) or on the skin (Group D, n=4). Ewes with healthy teats were controls (Group E, deposition into duct, n=5; Group F, deposition on skin, n=2). The ewes in Groups A, B or C developed clinical mastitis 5 h later, whilst the ewes in Group D developed it 2 d later; no control ewe developed clinical mastitis. In ewes with teat lesions, the organism was isolated from secretion samples and the California Mastitis Test became positive 5 h after challenge; neutrophils and lymphocytes were seen in Giemsa-stained secretion films from Group A or B ewes, whilst macrophages, neutrophils and lymphocytes in films from Group C or D ewes; neutrophils were predominating in films from Group E or F ewes. Inside the teats of Group A, B, C or D ewes, folds, hyperaemia and mucosal thickness were seen; histologically, subepithelial leucocytic infiltration was seen. In Group A or B ewes, no evidence of lymphoid tissue at the teat duct-cistern border was found. In Group C or D ewes, intense erosion and ulceration of the teat skin and conspicuous lymphoid tissue at the teat duct-cistern border, were evident; lesions characteristic of haemorrhagic mastitis were in the mammary parenchyma. In control ewes, subepithelial leucocytic infiltration in the teat duct and lymphoid tissue as above, were evident. We postulate that teat lesions can be predisposing factor to mastitis, by adversely affecting defences and speeding the process of infection and making it more severe.

Juvenile papillomatosis of the breast in a male infant with Noonan syndrome, café au lait spots, and family history of breast carcinoma

Juvenile papillomatosis (JP) of the breast is a rare condition, usually affecting women under 30 years of age. Although this is considered a benign lesion, follow-up is recommended for the patient and family since there is an association with a family history of breast carcinoma and increased risk of development of breast carcinoma. We report an infant with JP, Noonan syndrome (NS), café au lait spots, and family history of breast carcinoma. Seven previously reported cases of JP in males exist, two occurring in infants. The association between JP and NS has not been previously reported.

Tracheal, Bronchial, and Pulmonary Papillomatosis in Children

OBJECTIVES

To compare the clinical course of tracheal, bronchial, and pulmonary papillomatosis with clinical course of laryngeal papillomatosis in children.

STUDY DESIGN

The records of the 448 children with recurrent respiratory papillomatosis treated in St. Vladimir Moscow Children's Hospital between 1988 and 2003 were reviewed. In all cases, the diagnosis was confirmed histologically. Age at onset of symptoms, age at first surgery, number of surgical procedures, mean duration of surgical interval, possible causes, and age at a point of papillomatosis spread in the lower airways and course of the disease were analyzed.

SETTING

Academic children's hospital.

RESULTS

Papillomas extension down to lower airways was observed in 40 children (8.9%). Among 40 patients with lower airway recurrent respiratory papillomatosis, 8 (20%) demonstrated pulmonary involvement. The basic cause of papilloma extension to lower airways appeared to be tracheotomy performed in children with laryngeal papillomatosis (92.5% of cases). Incidence of satellite pharyngeal and esophageal papillomatosis is significantly higher in patients with lower airways papillomatosis, presenting evidence of lager process extension. The clinical course of lower airways papillomatosis is more aggressive as compared with laryngeal papillomatosis, and treatment efficacy in such children is lower.

CONCLUSIONS

All the patients with laryngeal papillomatosis having a history of tracheotomy require a regular endoscopic control and chest radiographs or computed tomography scanning because tracheal or pulmonary papillomatosis may occur in such patients even several years after decannulation. The prognosis for the disease after development of pulmonary papillomatosis is always serious.

Pulmonary hypertension due to recurrent juvenile laryngeal papillomatosis

Although pulmonary hypertension secondary to upper airway obstruction caused by adenotonsillar hyperplasia has been well described, the association between laryngeal papillomatosis and pulmonary hypertension has not previously been documented. We report three patients with pulmonary hypertension due to upper airway obstruction caused by laryngeal papillomatosis. Pulmonary hypertension can contribute to significant preoperative and postoperative morbidity and cause intraoperative complications. Preoperative diagnosis and treatment of pulmonary hypertension is therefore essential in these patients.

Subglottic jet ventilation for suspension microlaryngoscopy

High-frequency subglottic jet ventilation was used in 142 consecutive adults with grade I airways treated with suspension microlaryngoscopy. All cases were managed by the senior anesthesiologist (AP) and the large majority by the senior surgeon (JR), between 2000 and 2002. The laser was used in 30% of cases. There were few complications, none serious, associated with this technique in this series. The subglottic catheter never proved impossible to insert and only needed to be replaced by the supraglottic catheter in two patients because of limitation of visualization of the posterior glottis. The technique was used in a wide variety of surgical pathology from benign hyperfunction-related laryngeal pathology through paralytic vocal fold conditions through papilloma. Advantages and disadvantages over traditional intubation techniques and supraglottic jet ventilation are reviewed, including such issues as ease of intubation/ventilation, surgical exposure/control, maintenance of O2 and CO2 levels, and use in the limited/borderline airway.

Confluent and reticulated papillomatosis associated with tinea versicolor in three siblings

We describe three teenage siblings with confluent and reticulated papillomatosis, all presenting during a 6-month period. Two of the three patients had confirmed tinea versicolor, with positive potassium hydroxide scrapings, in association with this entity. This is the largest series of siblings with confluent and reticulated papillomatosis, and the only report describing family members having both confluent and reticulated papillomatosis and tinea versicolor. This report lends further evidence to the hypothesis that confluent and reticulated papillomatosis may be etiologically linked to tinea versicolor, and also suggests a genetic predisposition for it.

Extraesophageal acid reflux and recurrent respiratory papilloma in children

OBJECTIVE

Recurrent respiratory papillomatosis (RRP) is a benign infectious disease which is caused by the human papilloma virus (HPV). When it infects the larynx, hoarseness and airway obstruction are often the presenting symptoms. Latent virus is found in the laryngeal mucosa of many more patients than exhibit the disease. The factors which lead to virus activation have not been identified, however, extra-esophageal acid reflux disease (EERD) has been suggested as one of these factors.

METHODS

This is a case series of four patients with RRP who had increase in severity of their disease with the recognition of concurrent extra-esophageal acid reflux. The clinical course of the papillomatosis and the diagnosis and treatment of reflux are compared over time.

RESULTS

In all four cases, with identification and treatment of the EERD, control of the RRP improved, and in at least two patients, was complete with resolution of the EERD. Lapses in compliance with medications or behavioral and dietary recommendations in three out of four patients led to a rebound in symptoms and signs of RRP, including worsening of vocal quality and the endoscopic appearance of the larynx.

CONCLUSION

The clinical course of these patients suggests a link between the presence of EERD and RRP. The inflammation induced by chronic acid exposure may result in the expression of HPV in susceptible tissues. Prompt diagnosis and effective treatment of EERD should be considered in all patients with difficult to control RRP or with clinical presentation or endoscopic signs of EERD.

Idiopathic CD4+ lymphocytopenia and juvenile laryngeal papillomatosis

We report on an association of idiopathic CD4+ lymphocytopenia (ICL) and juvenile laryngeal papillomatosis (JLP) in a pediatric-aged patient. Because of a past medical history of recurrent lung infections and severe chickenpox in infancy, immunologic investigations were done at age 6 years. On several occasions, a CD4+lymphocyte count of <300 cells/mm3 was detected, supporting the diagnosis of ICL. During follow-up, both medical (interferon-alpha) and surgical treatments of JLP were only partially efficient. Our patient developed disseminated infection with Mycobacterium avium and died at 10 years of age. Human papillomavirus is an important pathogen in pediatric and adult patients with ICL. In pediatric patients with JLP who develop other unusually severe viral or opportunistic infections, immunological investigations should be considered.

[A case of laryngeal papilloma with sudden dyspnea]

Laryngeal papilloma is one of the most common non-malignant tumors of the larynx. In adult they are included to pre-cancerous diseases. In morphological examination, it is a solid tumor. Often it is possible to cure them during one surgical procedure. The disease is mostly localized on the anterior commissurae region, vocal fold, ventricules, and on the laryngeal surface of the epiglottis. If the malignant transformation is suspected, a large excision with margin has to be performed, completed by a histological evaluation. A case of a huge laryngeal papilloma with dyspnea is presented.

The association of bloody nipple discharge with breast pathology

BACKGROUND

It is believed that bloody spontaneous nipple discharge (SND) portends a greater chance of malignancy than nonbloody discharge, and that cytologic evaluation of SND assists in treatment planning. Our aims were to assess (1) the pathology of women with/without SND who require diagnostic breast surgery, (2) whether bloody SND is associated with a different spectrum of pathologic findings than nonbloody, and (3) whether SND cytology is influenced by pathologic findings.

METHODS

One hundred seventy-five women who underwent breast operation were enrolled. Cytologic evaluation was performed on Papanicolaou-stained cytospin preparations of SND.

RESULTS

Papilloma and hyperplasia (both without atypia) were more frequent in breasts with than without SND; breast cancer was more common in breasts without SND (P <.001 for all). All cases of breast cancer with SND, but only 33% without, contained a papilloma or papillary features. Seventy-five percent of cancers presenting with SND were nonbloody. Papilloma was the most common diagnosis in breasts with bloody SND and was more common (P=.017) than in breasts without, whereas hyperplasia was the most common diagnosis in breasts with nonbloody SND and was more common (P=.031) than in breasts with bloody SND. SND cytology was not significantly influenced by pathology.

CONCLUSIONS

Breast cancer can present as unilateral nonbloody SND, indicating the importance of surgical intervention. Papilloma was more common in women with SND than without and most often presented as bloody SND.

A patient without monocytes who had pulmonary renal syndrome

Clinical disorders with an isolated lack of monocytes have not been reported hitherto. The authors describe the case of a 38-year-old woman with pulmonary alveolar proteinosis and nephrotic syndrome caused by membranous nephropathy and widespread papillomatosis of the vulva. Immunologic studies showed normal levels of immunoglobulins and C2, C3c, and C4. Cryoglobulins and paraproteins were not detected. Antinuclear antibodies, antineutrophil cytoplasmic antibodies, and antiglomerular basement membrane antibodies were not detectable. Circulating immune complexes containing C1q, immunoglobulin G, and immunoglobulin M were elevated. The patient showed immunodeficiency that was characterized by complete anergy to intracutaneously administered recall antigens in vivo and to recall antigens in vitro. The immunodeficiency was accompanied by the absence of monocytes in the peripheral blood as well as in bone marrow cultures. In parallel, long-term bone marrow cultures and colony-forming cell assays did not result in the growth of monocytes. Mitogenic agents that require the presence of monocytes induced almost no T-cell proliferation (Concanavalin A: 5,841 counts per minute [cpm]), whereas agents that act directly on T cells induced intense T-cell proliferation (phytohemagglutinin: 110,001 cpm; OKT 3: 120,616 cpm; and pokeweed mitogen: 89,474 cpm). These data suggest that the pulmonary renal syndrome in this patient results from the lack of monocytes and the consecutive defect of antigen presentation and antigen clearance.

Dental and oral lesions in HIV infected patients: a study in Brazil

AIM

To determine the prevalence of dental and oral lesions, as well as treatment need, in a group of HIV sero-positive Brazilians. In addition, to test the association between oral manifestation of HIV infection and age, sex, mode of transmission and drug therapy.

METHOD

All HIV seropositive patients attending a dedicated dental clinic in Recife were invited to participate in the study. They were all examined by one trained and calibrated examiner and interviewed by one trained interviewer.

RESULTS

161 of 204 patients (78.9%) agreed to participate in this study. Most of the participants were male (76%), had acquired HIV sexually (74.5%), and were taking some form of antiretroviral therapy (70.8%). 33.5% had one or more oral manifestation of HIV. Candidiasis was the most common (28.6%), followed by hairy leukoplakia (9.3%), Kaposi sarcoma (2.5%), ulceration (2.5%), herpes simplex (1.2%), papiloma (0.6%), and 4.4% had periodontal disease. Only 1.2% reported xerostomia. There were no differences in the prevalence of oral manifestations of HIV infection between age groups, sexes, modes of transmission and types of drug therapy (P>0.05). The mean DMF-T score was 19 (SD 8) and 78.9% needed some form of dental treatment.

CONCLUSIONS

While the prevalence of oral manifestations of HIV/AIDS was low in this sample of HIV seropositive Brazilians, dental status was poor and need for dental treatment was high.

Oncocytic Schneiderian papilloma

Oncocytic Schneiderian papilloma, fungiform papilloma, and inverted papilloma are 3 morphologically separate tumors arising from the Schneiderian membrane. Oncocytic Schneiderian papillomas comprise about 3 approximately 5% of this entity. Old-aged group predominates. No sex predilection is noted. Multi-layered eosinophilic epithelium characterizes this kind of tumor. Exophytic and inverted growth pattern is found microscopically. It is often confused with sinonasal adenocarcinomas which contain only single-layered epithelium. Clinically, its behavior parallels inverted papillomas due to local recurrence and coexistence of malignancy. We reported a case of oncocytic Schneiderian papilloma arising from the anterior ethmoid sinus and extending to maxillary sinus antrum. Although destruction of the lamina papyracea was noted preoperatively, no malignancy was found microscopically. We adopted endoscopic approach and removed the tumor thoroughly. External approach was necessary if tumor extent was not feasible to endoscopic approach. The etiology of oncocytic Schneiderian papillomas remains unknown. However, it should be considered in the differential diagnosis of unilateral nasal polypoid lesions clinically.

Papillomatosis confined to the distal biliary tract--a rare cause of obstructive jaundice: report of a case

Based on the findings of a patient with recurrent obstructive jaundice due to papillomatosis of the distal bile duct, we herein describe the diagnostic difficulties and therapeutic options in this very rare disease. Endoscopic retrograde cholangiopancreatography and, in particular, cholangioscopy are the imaging procedures of choice if biliary papillomatosis is suspected. Due to the tendency of such patients to demonstrate malignant transformation and develop biliary cirrhosis with septic complications, an early and radical surgical resection is recommended in rare cases of localized papillomatosis. This approach may offer the only chance of a cure although the potential risk of multifocal recurrence cannot be ruled out. When considering a radical resection, intraoperative cholangioscopy is strongly recommended to confirm any localized papillomatosis and rule out any diffuse papillomatosis of the entire biliary tract.

[Laryngeal papillomatosis in adults: report on 4 cases]

Laryngeal papillomatosis is well-known as one part of benign lesions of the larynx in children under 15 years. Cases of papillomatosis are extremely rare in adults.

OBJECTIVES

To report our experience about 4 cases.

MATERIAL AND METHOD

It concerns 3 females and 1 male, who are in good health and without any disease in relation of upper respiratory tract or viruses. For all patients there is no familiar viral disease (especially cutaneous or genital). The age of patients is between 28 and 72 years. All clinical signs at the diagnosis aren't specific and are observed in other laryngeal diseases. Direct micro-laryngoscopy is mandatory in order to establish the right diagnosis and to perform the first stage of local treatment. Micro-instruments are used to remove these benign nipple-like without CO2 laser or local medicines or injections.

RESULTS

Our study mentions a frequent association of gastro-oesophageal reflux (3 cases). The average follow-up is 5 years and half and in this period, there is no malignant evolution.

CONCLUSION

The authors also review the literature and in particular the potential cause of laryngeal papillomatosis and new ideas on treatment of this unusual condition.

Hydrocephalus due to diffuse villous hyperplasia of the choroid plexus. Case report and review of the literature

Diffuse villous hyperplasia of the choroid plexus (DVHCP) that causes hydrocephalus by overproduction of cerebrospinal fluid is a very rare lesion and difficult to diagnose initially. We present a male infant who was diagnosed with communicating hydrocephalus at 16 months of age and treated initially by ventriculoperitoneal shunt. In the postoperative course, he developed massive ascites. Magnetic resonance imaging obtained after the operation revealed DVHCP. Resection of the choroid plexus of the left lateral ventricle was performed, and postoperatively, his ascites was resolved. We review the literature and discuss the diagnosis and treatment of this rare entity.

Lower airway papillomatosis in children

Laryngeal papilloma in children is a frequent disease caused by human papilloma virus (HPV) type 6 or type 11. This disease has a tendency to recur and the changes are histologically benign. In some cases papilloma may affect the lower levels of the respiratory tract. In this study, among 90 patients treated for laryngeal papillomatosis, in four children papilloma of trachea, bronchi and lung tissue were detected in endoscopic and radiological examination. This constitutes 4.4% of all patients. Compact nodules and acquired cysts between 5 and 50 mm long were found in chest X-rays and in computerised tomography. These cysts appeared from 4 to 8 years after establishing a diagnosis of laryngeal papilloma, and 1 year after recognising papilloma in the trachea. In all four children the presence of nodules and cysts in the lungs was preceded by recurrent pneumonia, emphysema or atelectasis of the lungs. All children with laryngeal papillomatosis should have a chest X-ray. Detection of acquired cyst-like changes in lung tissue in children with laryngeal papillomatosis is a warning of future papilloma in the trachea and bronchi, with involvement of lung tissue. In differential diagnosis of these changes in the lungs we should take into consideration the presence of papilloma in the bronchi. A prognosis of papillomatosis in the lower airways in children is always serious.

[Dacryolithiasis: diagnosis using nasal endoscopy]

PURPOSE

The purpose of this study was to assess the value of two new clinical findings for the diagnosis of dacryolithiasis discovered with nasal endoscopy: anatomical abnormalities of the Hasner valve (HV) and mucopurulent discharge visible at this valve. The value of these findings is compared with other clinical and radiological signs of dacryolithiasis. A hypothesis is developed as to the responsibility of the HV in the formation of dacryolithiasis.

METHOD

This study was prospective and based on 797 operations performed for epiphora: 647 endonasal dacryocystorhinostomies and 150 meatotomies of the HV, with systematic preoperative nasal videoendoscopy. Ninety dacryocystographies (DCGs) and 129 lacrimal computed tomographies (LCT) were preoperatively performed.

RESULTS

Dacryoliths were found in 55 of 797 patients (6.9%). The HV could be examined in 48 patients in the lithiasis group and in 687 patients in the control group. Mucopurulent discharge was observed in 22 patients with lithiasis (45.8%) and in 40 patients (5.8%) (p<10(-6)) of the control group. Anatomical abnormalities of the HV were found in 40 patients with dacryolithiasis (83.3%) as compared to 82 patients ing the control group (11.4%) (p<10(-6)). In 13 patients, the VH was very small (<2 mm), in 12 patients it was very long (>15 mm), and in 15 patients both abnormalities were observed. Other clinical signs were young age (mean, 48.2 years vs 59.1% in the control group) (p<0.05), a history of acute noninfectious dacryocystic retention (38.2% vs 9.5%) (p<10(-5)), partial obstruction of the lacrimal pathway (LP) (61.8% vs 30.5%) (p<10(-5)). The 28 LCTs that were performed in subjects who had lithiasis made it possible to diagnose 19 cases of dacryolithiasis and confirmed abnormalities of the HV causing narrowing of the LP in 20.

CONCLUSION

Dacryolithiasis is frequent and often misdiagnosed. When dacryolithiasis is suspected, a nasal videoendoscopic exam must be done to seek HV abnormalities and mucopurulent discharge at this valve. This latter finding, i.e., the association of mucopurulent discharge with a patent lacrimal system, has high specificity. The finding of numerous anatomical abnormalities of the HV may be an indication that congenital malformation of the HV is the cause of many cases of lithiasis.

[Unusual cause of tetraparesis in an adult]

A 61 year old male developed progressive spastic tetraparesis and paresis of the lower cranial nerves (IX, X and XI) after a minor spine-head trauma. Magnetic resonance depicted a partially cystic IV ventricular mass, extending to C1/C2 level. Neuropathology was compatible with choroids plexus papilloma (CCP). This case shows a rare clinical presentation of an infrequent adult tumour.

Biliary papillomatosis arising in a congenital choledochal cyst: report of a case

We report a rare case of biliary papillomatosis arising in a congenital choledochal cyst, with an anomalous junction of the pancreatobiliary ductal system (AJPBDS). A 50-year-old woman was admitted to our department with epigastralgia, and imaging studies showed two masses in the cystic common bile duct and an AJPBDS. We made a preoperative diagnosis of biliary tract cancer, considering the size of the masses and the presence of the AJPBDS, and performed a pylorus-preserving pancreatoduodenectomy. The resected specimen contained two papillary tumors, which were subsequently diagnosed as benign papillomas. Histopathological and oncological examinations indicated that the lesions were involved in the development and progression of carcinogenesis because a point mutation of the K- ras gene and overexpression of p53 protein were detected. These findings suggest that biliary papillomatosis is a precancerous lesion induced by an AJPBDS.

[Multifocal biliary papillomatosis: an indication for liver transplantation]

Biliary papillomatosis is a uncommon disease. Because of the high rate of recurrence and the possibility of malignant transformation, liver resection or transplantation was recommended. A case of diffuse bilobar biliary papillomatosis, in a 60 years old patient, responsible for cholangitis, cholestasis and for high portal pressure (esophageal varices grade I and II and hypersplenisme) is reported. The patient had had an external biliary drainage leading to an great loss of hydroelectrolytic component important. Opacification and biopsies under endoscopic control assert the right diagnosis. He was treated by a orthotopic liver transplantation. Post operative course was simple. In the 9th month, it was asymptomatic with a completely satisfactory evolution. The other therapeutic modalities was discussed, as well as the review of the literature.

Bacteraemia in free-ranging Hawaiian green turtles Chelonia mydas with fibropapillomatosis

Past studies of free-ranging green turtles Chelonia mydas with fibropapillomatosis (FP) in Hawaii have shown that animals become immunosuppressed with increasing severity of this disease. Additionally, preliminary clinical examination of moribund turtles with FP revealed that some animals were also bacteraemic. We tested the hypothesis that bacteraemia in sea turtles is associated with the severity of FP. We captured free-ranging green turtles from areas in Hawaii where FP is absent, and areas where FP has been endemic since the late 1950s. Each turtle was given an FP severity score ranging from 0 (no tumours) to 3 (severely affected). A fifth category included turtles that were stranded ashore and moribund with FP. We found that the percentage of turtles with bacteraemia increased with the severity of FP, and that the majority of bacteria cultured were Vibrio spp. Turtles with severe FP were more susceptible to bactaeremia, probably in part due to immunosuppression. The pattern of bacteraemia in relation to severity of disease strengthens the hypothesis that immunosuppression is a sequel to FP.

[Prevalence of papillomavirus infection among patients with laryngeal papillomatosis and the effects of some risk factors on the persistence of papillomaviruses in the upper respiratory tract]

Infection with high-risk human papillomaviruses is a significant risk factor of various benign and malignant human lesions in the upper respiratory tract, skin and the genital tract. The identification of particular human papillomaviruses types is important for identifying patients with premalignant lesions who are at risk of progression to malignancy. Our aim was to establish the prevalence of human papillomaviruses infection in the upper respiratory tract of patients with laryngeal papillomatosis, to identify viral types, to evaluate the relationship between some risk factors and persistence of human papillomaviruses in the upper respiratory tract and to determine the pattern of human papillomaviruses infection.

MATERIAL AND METHODS

The group of 36 patients with laryngeal papillomatosis and control group of 108 persons without any complains of respiratory system was examined. Epidemiologic characteristics and objective data were analyzed and routine laryngological examination was performed. Pharyngeal swabs of all persons and laryngeal biopsies of 17 patients were taken and analyzed for the presence of human papillomaviruses DNA. Viral typing using the polymerase chain reaction was performed.

RESULTS

Human papillomaviruses DNA was detected in all except one case of laryngeal papillomatosis; then only 23.15% of persons without complaints of respiratory system were found human papillomaviruses positive. Human papillomaviruses 6, 11 types were predominant (in 88.9% of patients and 19.4% of persons from control group). High-risk human papillomaviruses were detected in 52.78% of laryngeal papillomatosis cases and in 9.26% of control cases. Risk factors were noted statistically significantly more often in human papillomaviruses positive cases.

CONCLUSIONS

The prevalence of human papillomaviruses infection in the upper respiratory tract of patients with laryngeal papillomatosis is high; human papillomaviruses 6, 11 types are predominant. High-risk human papillomaviruses were noted statistically significantly more often in the group of patients with laryngeal papillomatosis. Inclination to diseases of respiratory system, dental caries, smoking, low living standard are statistically significantly related to human papillomaviruses persistence in the upper respiratory tract.

Human papillomavirus, type 40-associated papilloma, and concurrent Kaposi's sarcoma involving the anterior hard palate of an HIV-positive man

A number of oral lesions have been reported in association with HIV, including lesions caused by other viruses such as the epitheliotropic human papillomavirus (HPV). More than 90 types of HPV have been identified, with the less commonly encountered strains of HPV tending to show association with immunodeficiency states. In addition, HIV-infected patients may have Kaposi's sarcoma develop, a malignancy thought to be caused by human herpes virus, type 8. Recent evidence suggests a sexual mode of transmission for this virus. We report an HIV-positive man with a large, HPV type 40-associated papilloma of the anterior palate and a previously undiagnosed focus of Kaposi's sarcoma.

[Diagnostic pitfalls in childhood acute obstructive dyspnea]

Diagnosis of an acute obstructive dyspnea is very difficult because there are many possible causes. The authors reported the case of a 3.5-year-old boy with an atopic status who presented iterative asthma attacks which evolute to severity in spite of an appropriate therapy. Then suffocation occurred with a serious infectious context. The cause of the disease was diagnosed by respiratory tract endoscopic exam which allowed to detect a laryngeal papillomatis. The surgical extraction of this tumour cured the patient. Physiopathology of acute obstructive dyspnea in child was discussed. Upper airway obstructions are separated from lower pulmonary diseases. Two syndromes are very difficult to separate among upper airway obstructions: spasmodic laryngitis and subglottal laryngitis. They are considered in fact as different outward signs of the same disease: subglottal laryngitis is the infectious evolutive form of a spasmodic laryngitis in which atopic status exists. Laryngeal papillomatosis would be a favourising factor of infection. The authors conclude that respiratory tract endoscopic exam is very important to diagnose childhood acute obstructive dyspnea.

[Characteristics of psychoemotional sphere in children with chronic laryngeal obstruction]

45 children from 10 to 14 years of age with chronic laryngeal obstruction were examined psychologically. 29 of them had recurrent respiratory papillomatosis, 16 ones had cicatrical laryngostenosis. The majority of the examinees (65%) showed symptoms of posttraumatic stress syndrome (PTSS). The children develop PTSS one-two years after onset of laryngeal obstruction. Later, the children underwent persistent specific maladaptation personality disorders. Thus, children with recurrent laryngeal papillomatosis, especially with cicatrical laryngostenosis, should undergo psychological correction.

Ectrodactyly-ectodermal dysplasia-clefting syndrome (EEC): report of a case with perioral papillomatosis

We report a 13-year-old boy with ectodermal dysplasia, ectrodactyly, and syndactyly, hypospadias, photophobia, conductive hearing loss, and perioral papillomatosis. His father had ectrodactyly and hypotrichosis. The clinical picture suggested ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome. The presence of perioral papillomatosis, classically seen in Goltz syndrome, has been reported only once before in EEC syndrome.

Respiratory papillomatosis: a rare cause of collapse in a young adult presenting to the emergency department

Treating patients with rapidly deteriorating respiratory compromise in the emergency room is difficult and stressful. The patient in front of you is rapidly progressing towards total cardiorespiratory collapse and you may have no idea why. A case is reported of an adult presenting with impending cardiorespiratory collapse attributed to asthma who actually had upper airway obstruction caused by laryngeal papillomata. This case report reinforces the importance of airway assessment, gives an overview of respiratory papillomatosis, and reiterates both the non-surgical and surgical approach to the difficult airway.

Sinus inflammation associated with contralateral inverted papilloma

OBJECTIVE

To assess with computerized tomography (CT) the association of unilateral inverted papilloma (IP) and contralateral sinus inflammation.

DESIGN

Retrospective analysis of CTfindings in a sample of patients with unilateral IP, a sample with other unilateral sinonasal tumors, and normal controls.

PATIENTS AND METHODS

Sixteen patients with unilateral IP comprised the study population. Nine patients with other unilateral sinonasal tumors (five with squamous papilloma, two with squamous cell carcinoma, and one each with adenocarcinoma and large cell carcinoma) were used as a comparison population. Patients undergoing maxillofacial CTfor nontraumatic orbital conditions comprised the control sample (n = 12 sides). Each patient's preoperative CT scan was evaluated with a modified Lund-Mackay scoring system. The scores for the sides opposite the IPs were compared with the sides contralateral to other sinonasal tumors as well as to normal controls.

RESULTS

Analysis of all three samples' contralateral sides simultaneously using analysis of variance revealed a difference (p = 0.010). The contralateral sinus scores in IPs tended to be higher than the sides opposite the other sinonasal tumors (mean, 2.66 +/- 1.07 versus 1.18 +/- 0.76; p = 0.06). These in turn were higher than the normal controls (mean, 0.75 +/- 0.48; p < 0.02).

CONCLUSIONS

Unilateral IPs are associated with contralateral inflammation as detected by CT. This degree of contralateral inflammation is greater than that seen in other sinonasal tumors. The etiology of this association is unclear. A recent histological review suggested IP is an inflammatory polyp and not a true papilloma. Our data further suggest inflammation may be involved in the pathogenesis of IP. Further work is needed to better understand the pathophysiology and behavior of IP and to define its relationship to sinus inflammation.
