Riedel's thyroiditis: a case report and review of the literature

Riedel's thyroiditis is a very rare disease of unknown aetiology, occasionally associated with retroperitoneal and mediastinal fibrosis. It is a benign condition, but may be confused with an anaplastic carcinoma of the thyroid. The differential diagnosis with anaplastic carcinoma is assured only by intraoperative biopsy. The Authors report a clinical case: symptoms were a progressive enlargement of the thyroid gland, left recurrential palsy, dyspnoea and dysphagia. The surgical treatment was total thyroidectomy, performed with bilateral neurolysis of recurrent nerves. The patient was also under adjuvant corticosteroid treatment.     

Tuberculous thyroiditis: report of a case with a review of the literature

A 49-year-old Japanese woman was referred to our department for evaluation of a thyroid nodule. She underwent subtotal thyroidectomy with modified neck dissection for a follicular thyroid carcinoma, suspected on preoperative diagnosis. The histological diagnosis was tuberculous thyroiditis. She made an uneventful recovery and received antituberculous agents. At follow-up she remains well and is euthyroid. Reports on forty-four patients in the Japanese literature were read. Tuberculous thyroiditis must be differentiated from thyroid cancer and subacute thyroiditis. Surgery plus administration of antituberculous drugs is considered the treatment of choice.     

Hashimoto''s thyroiditis in association with Tolosa Hunt syndrome: a case report

The effect of cisapride on constipation in para and tetraplegia is well known. We have investigated the effects of this prokinetic drug on anorectal activity and on the function of the lower urinary tract. One result of the anorectal study showed a significant increase in activity and a reduction in compliance of the ampulla. The urodynamic study demonstrated earlier and higher amplitude reflex contractions in hyperactive bladders; hypoactive bladders significantly reduced their compliance. No functional alterations of striated urethral sphincter were observed.     

Megaesophagus and pneumonia associated with Mycobacterium chelonei. A case report and a literature review

The case of a 37-year-old woman who developed a subacute, bilateral, noncavitary pneumonia 5 years after a colon interposition esophagoplasty is presented. Mycobacterium chelonei, subspecies abscessus, was assigned a pathogenic role based on the findings of (1) a clinical and roentgenographic picture consistent with tuberculosis, (2) sputum smears showing acid-fast bacilli, (3) repeated sputum cultures yielding heavy growths of Mycobacterium chelonei, subspecies abscessus, and (4) a 12-mm by 12 mm-skin test response to homologous antigen (purified protein derivative-CL) with no response to an equivalent dose of purified protein derivative-S. The patient recovered fully without significant antituberculous chemotherapy. A survey of the literature revealed 11 similar case reports featuring a documented association between megaesophagus and pulmonary infection with rapidly growing mycobacteria.     

Clinical efficacy of dirithromycin in patients with bacteremic pneumonia

Dirithromycin is a new macrolide antimicrobial drug with a long half-life (44 hours) that reaches high tissue concentrations, thus permitting once-daily oral dosing and shorter courses of therapy. Soon after absorption, dirithromycin enters the tissue so rapidly that serum concentrations are comparatively low. It could be hypothesized that these low serum levels could endanger the outcome in patients with bacteremic pneumonia. We reviewed the database on dirithromycin pneumonia (consisting of 1108 patients randomized to receive dirithromycin or erythromycin in two double-masked trials) to ascertain its efficacy in patients with community-acquired pneumonia and concomitant bacteremia. Fourteen (2.5%) of 555 dirithromycin-treated patients and 10 (1.8%) of 553 erythromycin-treated patients had bacteremia. A favorable clinical response posttherapy was observed in 92.3% and 88.9% of these patients with a response assigned, respectively. Overall, favorable response rates were comparable between the two groups in the bacteremic subsets: patients with pneumococcal bacteremia, patients with nonbacteremic pneumococcal pneumonia, and all patients enrolled with acute pneumonia who had a posttherapy clinical response. In the treatment of patients with mild or moderate community-acquired pneumonia, including those with unsuspected and incidental bacteremia, dirithromycin is an effective macrolide antimicrobial drug.     

Streptococcal pyomyositis: case report and review

Pyomyositis is most often associated with Staphylococcus aureus infections after trauma. We describe an unusual presentation of pyomyositis of the chest wall secondary to group A betahemolytic streptococcus infection in a 15-month-old child with acute abdominal symptoms. In addition, the patient had no history or evidence of trauma to the affected area. Pyomyositis presenting in this manner secondary to group A beta-hemolytic streptococcus infection in the absence of a primary varicella infection has not been previously reported.     

MURCS association: case report and review

We report on a 25 year old woman with aplasia of the Müllerian duct, unilateral renal agenesis, and anomalies of the cervicothoracic somites (MURCS association). Growth retardation and facial asymmetry were also present. A review of published reports allows MURCS association to be distinguished from related associations, sequences, and syndromes. Moreover, sporadic occurrence, the broad spectrum of associated anomalies, and the involvement of different organ systems closely related in early embryogenesis are arguments for considering MURCS association as the consequence of a developmental field defect.     

Infective endocarditis associated with upper endoscopy: case report and review

We have compared fronto-central and bifrontal montages using a new EEG monitor, the Aspect A-1000. The monitor uses bispectral analysis to derive an index of anaesthetic depth, the bispectral index (BIS). We compared reliability, impedance and BIS for each montage. ECG electrodes placed in a bifrontal montage were more reliable than silver dome electrodes in a fronto-central montage and both types of electrodes had impedances in the clinically useful range. However, BIS values derived from each montage were found to differ in an unpredictable manner. The bifrontal montage is easy to apply and reliable but it is not comparable with a fronto-central montage. We conclude that the BIS may be useful for following trends in anaesthetic depth in individual cases but it is less helpful when making comparison between patients or as a single value.     

Choroidal melanoma: a review and case report

BACKGROUND: Choroidal melanoma is the most common primary intraocular malignancy in adults. The ongoing Collaborative Ocular Melanoma Study (COMS) was designed to provide specific answers for the management of medium and large choroidal melanomas. The present consensus among authorities is that small (< 3 mm thick) suspected choroidal melanomas can be conservatively managed with periodic observation for evidence of growth. CASE REPORT: Dilated fundus examination of a 68-year-old man revealed a pigmented uveal lesion straddling the ora serrata inferiorly at 5:30 in the right eye. It measured 5 mm in diameter with transillumination and 2.89 mm in thickness with B-scan ultrasonography. Questioning a small choroidal melanoma the patient was referred to an ocular oncologist, who confirmed the lesion was suspicious for choroidal melanoma. CONCLUSION: Although there are clinical signs that suggest lesion growth, true growth must be recorded with serial photographs, ultrasound, and transillumination. Active therapy should usually begin once lesion growth is documented.     

Mesenteric panniculitis: case report and literature review

Mesenteric panniculitis is an extremely rare inflammatory condition of the adipose tissue of unknown etiology in which the mesentery is replaced with fibrosis. Knowledge of this rare syndrome should prevent any unwarranted aggressive therapy and help to use the clinical, radiological, and surgical sources to obtain the diagnosis. This paper is a review of symptomatology, pathology, treatment, and outcome of this disorder. A case report is described that presented with obstruction of the sigmoid colon.     

Chorea gravidarum: a case report and review

A 23-year-old pregnant Pakistani female presented with hemichorea and hemiballismus at six weeks gestational age. Similar symptoms had occurred during a previous pregnancy resulting in a spontaneous abortion. Chorea gravidarum, a disorder characterized by choreiform and athetoid movement presenting during pregnancy, is rare. In the past, rheumatic disease was generally the etiology, but today, collagen vascular disease should also be considered. Treatments include neuroleptics for symptomatic relief and therapies targeted toward the underlying pathology.     

Gestational psittacosis: case report and literature review

OBJECTIVE: To evaluate the safety, efficacy, and biocompatibility of icodextrin- and glucose-containing dialysis fluid during continuous cycling peritoneal dialysis (CCPD), patients were treated for 2 years with either icodextrin- or glucose-containing dialysis fluid for their daytime dwell (14-15 hours). Prior to entry into the study, all patients used a standard glucose solution (Dianeal 1.36%, 2.27%, or 3.86%, Baxter, Utrecht, The Netherlands). DESIGN: Open, randomized, prospective, two-center study. SETTING: University hospital and teaching hospital. PATIENTS: Both established and patients new to CCPD were included. A life expectancy of more than 2 years, a stable clinical condition, and written informed consent were necessary before entry. Patients aged under 18, those with peritonitis in the previous month, and women of childbearing potential, unless taking adequate contraceptive precautions, were excluded. Thirty-eight patients entered the study, and 25 (13 glucose, 12 icodextrin) had a follow-up period of 12 months or longer in December 1996. MAIN OUTCOME MEASURES: Serum icodextrin metabolites: one to five glucose units (G1-G5), a high molecular weight fraction (G > 10), and total carbohydrate level, as well as a biochemical profile were determined every 3 months in combination with all other study variables. RESULTS: In icodextrin-treated patients, serum disaccharide (maltose) concentrations increased from 0.05 +/- 0.01 (mean +/- SEM) at baseline, to an average concentration in the follow-up visits of 1.14 +/- 0.13 mg/mL (p < 0.001). All icodextrin metabolites increased significantly from baseline, as illustrated by the serum total carbohydrate minus glucose levels: from 0.42 +/- 0.05 mg/mL to an average concentration in the follow-up visits of 5.04 +/- 0.49 mg/mL (p < 0.001). At the same time, serum sodium levels decreased from 138.1 +/- 0.7 mmol/L to an average concentration in the follow-up visits of 135.4 +/- 0.8 mmol/L (p < 0.05). However, after 12 months the serum sodium concentration increased nonsignificantly (NS) from baseline to 136.6 +/- 0.9 mmol/L, after an initial decrease. Serum osmolality increased significantly from baseline in icodextrin users at 9 and 12 months, but did not differ significantly from glucose users in any visit. In icodextrin-treated patients, the calculated serum osmolal gap increased significantly from 4.1 +/- 1.4 mOsm/kg to an average of 11.8 +/- 1.7 mOsm/kg (p < 0.01). The sum of the serum icodextrin metabolites in millimoles/liter equaled the increase in osmolal gap. Body weight increased in icodextrin users (71.9 +/- 2.8 kg to 77.8 +/- 3.0 kg; NS). Clinical adverse effects did not accompany these findings. Residual renal function remained stable during follow-up. CONCLUSIONS: The serum icodextrin metabolite levels in the present study increased markedly and were the same as those found previously in continuous ambulatory peritoneal dialysis patients treated with icodextrin, despite the longer dwell time for CCPD patients (14-16 hr versus 8-12 hr). The initial decrease in serum sodium concentration was followed by an increase to a concentration not different from baseline at 12 months. The pathophysiology of this finding is speculated. Calculated osmolal gap in icodextrin patients increased significantly (p < 0.01) at every follow-up visit, and could be explained by the serum icodextrin metabolite increase. We encountered no clinical side effects of the observed levels of icodextrin metabolites.     

Ectodermal dysplasia: a review and case report

Ectodermal dysplasia is a hereditary disease characterized by a congenital dysplasia of one or more ectodermal structures and their accessory appendages. Common manifestations include defective hair follicles and eyebrows, frontal bossing with prominent supraorbital ridges, nasal bridge depression, and protuberant lips. Intraorally, common findings are anodontia or hypodontia, conical teeth, and, consequently, generalized spacing. The patient may suffer from dry skin, hyperthermia, and unexplained high fever as a result of the deficiency of sweat glands. The present review focuses on the clinical manifestations, classifications, and diagnosis of ectodermal dysplasia. A 6-year-old girl, described in the case report, exhibited many of the manifestations of ectodermal dysplasia as well as behavioral problems and a severe gag reflex. The treatment to improve her appearance and oral function included a removable prosthesis, acid-etch-retained indirect resin composite veneers, and a fixed partial denture.     

Primary pulmonary botryomycosis: case report and review

Botryomycosis is an uncommon bacterial disease characterized by the microscopic formation of eosinophilic granules that resemble those of infection by Actinomyces species. The diagnosis of botryomycosis can be made when microscopic inspection and culture of the granules reveal gram-positive cocci or gram-negative bacilli. Botryomycosis is caused by common bacterial pathogens including Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, yet the host and microbial factors that contribute to the pathobiology remain unknown. Pulmonary botryomycosis can resemble actinomycosis, tuberculosis, or invasive carcinoma by causing a mass lesion with constitutional symptoms. Radiographically, it invades bone and disrupts tissue planes. Successful treatment often requires a combination of both surgical debridement and long-term antimicrobial therapy. We report a case of primary pulmonary botryomycosis and review the literature on this unusual infectious process.     

Kenny syndrome: case report and literature review

A 34-month-old girl presented with a clinical picture of Kenny syndrome. The clinical manisfestations included growth retardation, persistent open anterior fontanelle, prominent forehead, mid-facial dysplasia, hypocalcemic tetany and characteristic radiologic skeletal abnormalities. Serum levels of immunoreactive parathyroid hormone (PTH) remained inappropriately low during hypocalcemic episodes in the neonatal period; indicating that hypocalcemia was a consequence of the hypoparathyroid state. This is the first reported case of Kenny syndrome in Taiwan. The literature on the pathogenesis, etiology and genetic basis of this disorder is reviewed in this paper.
