We have been involved in the analysis of DiGeorge syndrome and related diagnoses since 1982 and have evaluated a large number of patients with the deletion. We describe our cohort of 250 patients whose clinical findings help to define the extremely variable phenotype associated with the 22q11.2 deletion and may assist clinicians in providing genetic counseling and guidelines for clinical management based on these findings.

Research paper thumbnail of Usefulness of Computed Tomographic Scan in the Evaluation of Sensorineural Hearing Loss in Children

Seventy consecutive cases, spanning 4.5 years, were identified and individual computed tomography films reviewed. Cases were analyzed with respect to patients' age, duration of hearing loss, sudden onset vs progressive loss, unilateral vs bilateral, and other symptoms. Of the 70 computed tomographic scans, nine showed temporal bone or other intracranial abnormalities. The majority of these findings were localized to structures in the posterior and middle cranial fossae. No eight nerve tumors were identified. Congenital hearing loss and hearing loss secondary to viral infections are the most common cause of sensorineural hearing loss when discovered in early childhood and, often, have no radiographic abnormality. The decision to explore an ear for a presumed perilymph fistula is based almost exclusively on the history and physical examination, and not on the demonstration of any radiographic findings. For the children presenting with stable hearing impairment in the absence of other findings, computed tomographic scans were either negative or did not contribute to diagnosis. Since tumors of the eighth nerve are rare in children under 16 years of age (without neurofibromatosis), and radiologic studies have a low yield in identifying perilymph fistulas, the routine use of computed tomographic imaging in such children may be unjustified.

Design: Retrospective study. Setting: A tertiary care center. Patients: Thirty-three patients, with a mean age of 4.5 years, underwent surgical treatment for pilomatrixoma (n = 38) between 1989 and 1997. Intervention: All patients were treated surgically. In 34 cases, a direct approach was used to achieve complete removal of the lesion with (n = 11) or without (n = 23) skin resection. In the remaining 4 cases, an indirect approach via a parotidectomylike incision was used. Results: In 88% of cases, the presenting symptom was a hard, slow-growing, subcutaneous tumor. The lesion was associated with pain and inflammation in 7 cases (18%) and abscess or ulceration in 4 cases (11%). Twentynine patients presented with single nodules and 4 presented with multiple occurrences. The lesions were located on the face (cheek, eyelid, or forehead) in 20 cases (53%), on the neck in 8 cases (21%), in the parotid region in 8 cases (21%), and on the scalp in 2 cases (5%). Conclusions: Pilomatrixoma is a rare, benign skin tumor, but practitioners should be aware of its clinical features. Diagnosis is usually easy based on clinical findings, but computed tomographic scan is helpful, especially in cases involving tumors located in the parotid region. Spontaneous regression is never observed. Complete surgical excision, including the overlying skin, is the treatment of choice.

These uncommon tumors, which affect all ages, arise most frequently from the brachial plexus, sympathetic chain, and the cranial nerves or their branches. An enlarging mass is the most common initially appearing symptom. Diagnosis may be difficult and rests heavily on gross evidence of a relationship between the tumor and its nerve of origin. Histologically, the lesions are composed of spindle cells with varying degrees of pleomorphism in a pattern that is frequently undistinguishable from fibrosarcomas. Ultrastructural studies may be helpful in establishing the neurogenic origin of these tumors. Neurogenic sarcoma of the head and neck has an extremely poor prognosis. Surgery remains the cornerstone of treatment, although radiotherapy is important for palliation.

These tumors are uncommon in children. Granular cell tumors in adults have a predilection for the head and neck, but this was not noted in our experience with children. Of the 22 granular cell tumors diagnosed and managed at the Children's Hospital of Philadelphia from 1960 to 1988, 7 were from the head and neck. One child with a subglottic granular cell tumor is of particular interest and is presented in detail.

Most research in this area, however, has examined whether nursing homes have or use any of a list of available technologies. We sought to develop an empirical framework for understanding the intersection between specific uses of HIT and clinical care processes. Using the nominal group technique, we conducted a series of focus groups with different types of personnel who work in nursing homes (administrators, directors of nursing, physicians, mid-level practitioners, consultant pharmacists, and aides). The resulting framework identified key domain areas that can benefit from HIT: transfer of data, regulatory compliance, quality improvement, structured clinical documentation, medication use process, and communication. The framework can be used to guide both descriptive and normative research.

The mean flow rate of stimulated whole saliva decreased 83.3% during a 6-week treatment period. The striking reduction in saliva output was accompanied by significant increases in saliva Na+, Cl-, Ca++, Mg++ and Prot.- concentrations and by a decrease in saliva HCO3- content. The xerostomic saliva was more concentrated and had a greater salinity than the pretreatment saliva in each instance. In contrast, none of the serum electrolytes measured was significantly altered by the subtotal salivary shutdown.

When this diagnosis is suspected, the functional and anatomical integrity of the brachial plexus and cervical spinal cord must be carefully assessed. A thorough search for other signs of neurofibromatosis (von Recklinghausen's disease) must also be completed. The distinction between neurilemoma and neurofibroma is an important and useful one to know. Evaluation by a pathologist who is well versed in neural tumors is mandatory for appropriate treatment of these usually benign lesions. Surgical intervention, adequately prepared on the basis of the patient's age, the amount of neural impairment, and the extent and histology of the tumor requires a surgeon who is experienced in peripheral nerve surgery and in microdissection techniques. Long-term follow-up is necessary to monitor the growth of known tumors, the detection of malignant change, and the appearance of other stigmata of von Recklinghausen's disease.

Streptococcus pneumoniae was the predominant organism recovered (63%). Three cases of Hemophilus influenzae, alone or in combination with S pneumoniae, were identified. Other organisms found were Staphylococcus albus, Neiserria species, Group A B-hemolytic Streptococcus, and anaerobes. In four patients (I3%) no organism was recovered. All isolates were ampicillin susceptible. No relationship was found between WBC, temperature, or age and the organism recovered. Tympanocentesis did not provide any information resulting in an alteration of therapy. Tympanocentesis may he indicated for relief of pain or for periodic surveillance of organism sensitivities, but is not justified in the emergency department for uncomplicated acute otitis media.

Long-term follow-up of these patients has revealed little difference in the incidence of tube occlusion or early extrusion. In addition, there were several disadvantages noted with the Biolite tubes: incomplete coating of the tube (especially within the lumen), shedding of the Biolite coating over time, "tattooing" of the tympanic membrane, poor otoscopic visibility, and the higher cost of these tubes. Since the Biolite tube has no documented advantages and, actually, several disadvantages, we believe its use in the treatment of middle ear disorders should be discontinued until significant benefits are demonstrated and present deficiencies are corrected.

It is most commonly caused by poor oral and facial muscle control. Contributing factors may include hypersecretion of saliva, dental malocclusion, postural problems, and an inability to recognize salivary spill. Sialorrhea causes a range of physical and psychosocial complications, including perioral chapping, dehydration, odor, and social stigmatization, that can be devastating for patients and their families. Treatment of sialorrhea is best managed by a clinical team that includes primary health care providers, speech pathologists, occupational therapists, dentists, orthodontists, neurologists, and otolaryngologists. Treatment options range from conservative (i.e., observation, postural changes, biofeedback) to more aggressive measures such as medication, rad...

These cysts may become painful and unsightly, often initiating a request for therapeutic intervention. There are several treatment options described in the literature. We report the use of doxycycline sclerotherapy in the treatment of a child with BLCs of the parotid.

Diagnosis relies upon culture, acid-fast bacilli (AFB) staining, chest radiograph, purified protein derivative (PPD) test, and clinical features. Computed tomography (CT) and magnetic resonance (MR) imaging may provide valuable information in the work-up of children with cervical masses. We reviewed 11 CT and 5 MR studies of children with a clinical diagnosis of NTM infection. Specific findings included stranding of the subcutaneous fat, thickening and enhancement of the overlying skin, obliteration of the tissue palnes, and multichambered masses. One patient had calcifications within the mass. MR with contrast better demonstrated the soft tissues and is our recommended imaging modality, although CT is more likely to detect calcifications within the neck mass.

Analysis was performed with respect to primary diagnosis, age, duration of tracheostomy and hospitalization, early and late complications and mortality. While the incidence of tracheostomy per hospital admission decreased over the period of review, there was substantial increase in duration of tracheotomy. Approximately half of the patients sustained complications. While overall mortality approached 28%, tracheostomy-related deaths occurred in only eight patients (2%). Almost one fifth of children with tracheostomies were discharged to home care, and 3% were involved in our home ventilator program.

The diagnosis must be considered in any infant presenting with a lateral neck mass. Although its natural history favors spontaneous regression, the mass may initially grow in size. The purpose of treatment is the prevention of torticollis and craniofacial asymmetry. The initial treatment is non-surgical, passive and active exercises. Only when this treatment fails should surgery be performed. The disappearance of the lesion is not always a predictable sign. A small number of children will develop delayed torticollis or craniofacial asymmetry. It is important that parents be informed of this possibility and of the necessity for long term follow-up.

Only when this treatment fails should surgery be performed. The disappearance of the lesion is not always a predictable sign. A small number of children will develop delayed torticollis or craniofacial asymmetry. It is important that parents be informed of this possibility and of the necessity for long term follow-up.
