Abstract
Human skull is made up of many bone joints connected by sutures. The sutures fuse in later life after the complete growth of the brain. If any of these sutures closes early, it may interfere with the normal growth of the brain. The developing brain may exert pressure on the skull and may grow in the direction of the other open sutures. Premature sutural fusion may occur alone or together with other anomalies, making up various syndromes. Crouzons syndrome is an example of such a syndrome that is associated with premature synostosis of the sutures of the skull. Presented in this article is a case of Crouzons syndrome seen in a boy aged 9 years.

Abstract
BACKGROUND Duodenal somatostatinoma is a rare neuroendocrine neoplasm. A better prognosis can be obtained if these tumors are resected at an early clinical stage. Endoscopic punch biopsy has been the method most commonly used for the preoperative diagnosis of neuroendocrine duodenal tumors. To the best of our knowledge, endoscopic fine needle aspiration biopsy (FNAB) of duodenal somatostatinoma has not been reported before. CASE A 41-year-old, black female presented with upper gastrointestinal bleeding as well as elevated bilirubin, liver enzymes and glucose. Computed tomography, esophagogastroduodenoscopy and endoscopic retrograde cholangiopancreatography (ERCP) detected a mass at the region of the ampulla of Vater partially obstructing the pancreatic duct. The initial punch biopsy yielded only intestinal mucosa. Subsequent endoscopic FNAB suggested the diagnosis of a neuroendocrine neoplasm, as confirmed by additional punch biopsies. Immunohistochemical and electron microscopic studies disclosed somatostatin production by the tumor, which was resected through a modified Whipple procedure. The patient recovered fully. CONCLUSION This case demonstrates the usefulness of endoscopic FNAB in diagnosing submucosal gastrointestinal neuroendocrine tumors.

Abstract
Mississippi has the highest prevalence of blastomycosis in the country. In 20 years and 5 months there were 123 patients treated for blastomycosis at the University of Mississippi Medical Center. Among these, 107 patients had lung involvement and nine patients (8.4%) developed acute respiratory distress syndrome. Seven of the nine patients (78%) died of respiratory failure. In six patients, the lungs were the only organs involved. The three other patients had involvement of other organs as well. Average survival after the onset of acute respiratory distress syndrome was 6.9 days (range, 2 to 17 days). Acute respiratory distress syndrome can be triggered by pulmonary infections caused by bacterial diseases and other fungi. Massive proliferation of yeasts in the pulmonary parenchyma is the typical finding of patients with blastomycosis and acute respiratory distress syndrome. Underlying diseases that lead to immunodepression were present in only one patient and probable partial immunodepression was present in two other patients. Data from 19 other cases reported in the literature are discussed. Ann Diagn Pathol 5:1-9, 2001.

Abstract
Blastomycosis can only be diagnosed through the identification of the yeasts of Blastomyces dermatitidis in body fluids, tissues, or cultured material. The charts from 123 patients treated for blastomycosis at the University of Mississippi Medical Center from January 1980 through May 2000 were reviewed to determine the role of wet preparation, cytology, histology, and culture in diagnosing this fungal disease. Cytology uncovered the etiologic agent in 56.1% of all cases and in 71.8% of pulmonary cases. Cytology also was the first method to disclose the fungus in 57.7% of pulmonary cases. Sputum was the cytology specimen examined in 51% of the patients. In 69 patients with lung involvement, pulmonary cytology was positive in 97% of cases. Wet preparation was the second method to most commonly uncover the fungus in 37.4% of all cases. Histology was the third method with 32.5% of positive cases. Cultures were positive in 64.2% of all cases but they were the first to detect the fungus in only 3.2% of all patients. There was pulmonary involvement in 87% of patients, cutaneous involvement in 20%, osseous involvement in 15%, and central nervous involvement in 3%. In the medical literature the relative proportion of pulmonary versus disseminated disease clearly increased in series reported after 1959. Proportionally to the pattern of patients admitted to the University of Mississippi Medical Center, there is a clear predominance of black males among patients with blastomycosis followed by black females. White females constitute the sex/ethnic group least affected by this fungal disease.

Abstract
BACKGROUND Symptomatic striated muscle involvement in sarcoidosis is rare. Muscle biopsy is usually required for the diagnosis. Fine needle aspiration biopsy (FNAB) has been successfully used in diagnosing soft tissue lesions. To the best of our knowledge, FNAB of sarcoid myositis has not been reported. CASE A 31-year-old, black female with a history of sarcoidosis presented with an enlarging, painful, left calf mass. Infected thrombi were suspected. FNAB showed numerous loosely arranged epithelioid histiocytes, multinucleated giant cells and skeletal muscle cells. The overall cytologic picture was that of granulomatous myositis. The cytologic features coupled with the patient's history and magnetic resonance imaging findings suggested sarcoid myositis. Subsequent muscle biopsy showing noncaseating granulomata and negative stains for organisms confirmed the diagnosis of nodular sarcoid myositis. CONCLUSION Nodular sarcoid myositis can be suggested by FNAB cytology in a patient with a past history of sarcoidosis.

Abstract
BACKGROUND Iron plays a role in free radical-mediated tissue injury, including cisplatin-induced nephrotoxicity. However, the source of iron (catalyzing free radical reactions) is not known. We examined the role of cytochrome P-450 as a source of catalytic iron in cisplatin-induced nephrotoxicity both in vivo and in vitro. METHODS Cisplatin-induced acute renal failure was produced in rats by intraperitoneal injection of cisplatin (10 mg/kg body wt). Piperonyl butoxide, a cytochrome P-450 inhibitor, was administered intraperitoneally (400 mg/kg body wt twice at 48-hr intervals) prior to cisplatin injection. The effects of cisplatin in the absence or presence of piperonyl butoxide on the belomycin-detectable iron, cytochrome P-450 content in the kidney, and renal functional and histological changes were evaluated. In an in vitro study, the effect of cytochrome P-450 inhibitors, cimetidine or piperonyl butoxide, on cisplatin-induced cytotoxicity and catalytic iron release from LLC-PK1 cells was examined. RESULTS In cisplatin-treated rats, there was a marked decrease in the cytochrome P-450 content specifically in the kidney, accompanied by increased bleomycin-detectable iron content in the kidney. Piperonyl butoxide prevented cisplatin-induced loss of cytochrome P-450 as well as the increase of bleomycin-detectable iron in the kidney, along with both functional and histological protection. Both cimetidine and piperonyl butoxide prevented cisplatin-induced increase in bleomycin-detectable iron and cytotoxicity in LLC-PK1 cells. Treatment of cimetidine did not affect cellular uptake of cisplatin. CONCLUSION Cytochrome P-450, a group of heme proteins, may serve as a significant source of catalytic iron in cisplatin-induced nephrotoxicity.

Abstract
This paper is a clinical report on the use of eggshell as a bone substitute in oral surgery. Five volunteers who presented with a cystic cavity of the jaw with a mean size of 2 x 1 cm, were enrolled in the study. After enucleation of the cyst, the cavity was packed with eggshell powder. The results were assessed by clinical examination and repeated radiological examination at 2, 4, and 6 weeks. Two operative sites were checked at 2 months for histological examination. Clinically, the eggshell implants were very well tolerated. In 3 out of 5 patients, a progressive opacification of the cavities with a centripetal ossification occurred within 6 weeks. In one patient, a generalized resorption was noticed. Histological examination confirmed that eggshell powder was not osteoinductive, but it enhanced the bone regeneration from the margins. In conclusions, eggshell powder is a worth-while bone substitute because it is a safe and easily available material. However, only a modest beneficial effect can be expected on bone regeneration.

Abstract
We report a case of transitional cell carcinoma of the urinary bladder metastatic to the penis. The diagnosis was established by fine needle aspiration biopsy (FNAB). Malignant cells showed mucinous differentiation. Ancillary studies carried out in the FNA material as well as in the primary bladder carcinoma suggested transitional cell carcinoma with mucinous differentiation. FNAB proved to be effective in diagnosing a secondary neoplasm to the penis. Mucoid differentiation of urothelial cells can be seen in FNAB specimens and might pose a problem in differential diagnosis.

Abstract
Cisplatin is a widely used antineoplastic agent that has nephrotoxicity as a major side effect. The underlying mechanism of this nephrotoxicity is still not well known. Iron has been implicated to play an important role in several models of tissue injury, presumably through the generation of hydroxyl radicals via the Haber-Weiss reaction or other highly toxic free radicals. In the present study we examined the catalytic iron content and the effect of iron chelators in an in vitro model of cisplatin-induced cytotoxicity in LLC-PK1 cells (renal tubular epithelial cells) and in an in vivo model of cisplatin-induced acute renal failure in rats. Exposure of LLC-PK1 cells to cisplatin resulted in a significant increase in bleomycin-detectable iron (iron capable of catalyzing free radical reactions) released into the medium. Concurrent incubation of LLC-PK1 cells with iron chelators including deferoxamine and 1,10-phenanthroline significantly attenuated cisplatin-induced cytotoxicity as measured by lactate dehydrogenase (LDH) release. Bleomycin-detectable iron content was also markedly increased in the kidney of rats treated with cisplatin. Similarly, administration of deferoxamine in rats provided marked functional (as measured by blood urea nitrogen and creatinine) and histological protection against cisplatin-induced acute renal failure. In a separate study, we examined the role of hydroxyl radical in cisplatin-induced nephrotoxicity. Incubation of LLC-PK1 cells with cisplatin caused an increase in hydroxyl radical formation. Hydroxyl radical scavengers, dimethyl sulfoxide, mannitol and benzoic acid, significantly reduced cisplatin-induced cytotoxicity and, treatment with dimethyl sulfoxide or dimethylthiourea provided significant protection against cisplatin-induced acute renal failure. Taken together, our data strongly support a critical role for iron in mediating tissue injury via hydroxyl radical (or a similar oxidant) in this model of nephrotoxicity.

Abstract
OBJECTIVE To evaluate the presence of tyrosine-rich crystalloids (TRC) in fine needle aspiration (FNA) specimens of pleomorphic adenomas of salivary gland. STUDY DESIGN FNA specimens from 12 patients were reviewed, and the percentage of cases showing TRC was established. The staining properties of the TRC were evaluated as well as spontaneous fluorescence under ultraviolet (UV) light. RESULTS Of the 12 pleomorphic adenomas, 4 showed TRC (30%) in the smears. Among the eight cytologically negative cases there were two that showed a few TRCs on histology. All positive cases were from African American patients. TRC stained weakly with Papanicolaou stain. TRC were deep blue with Diff-Quik. They fluoresced under UV light. CONCLUSION TRC could be detected in FNA specimens. They were best seen under UV light. The Papanicolaou technique stained TRC very pale, making them difficult to see. Diff-Quik stained TRC dark blue, mimicking deposits of dye. The amount of TRC in histology paralleled the detection rate in cytology.

Abstract
A case of tumor-like extramedullary hematopoiesis (EMH) of the liver diagnosed by fine-needle aspiration cytology guided by computer tomography (CT) is reported. The initial clinical diagnosis was metastatic carcinoma from an adrenal gland primary. Five other cases of tumor-like EMH diagnosed by FNA have been presented in the literature. In two of the cases, the primary clinical diagnosis was metastatic tumor. The most common location for tumor-like EMH is paravertebral and intrathoracic. Three such cases of paravertebral tumor-like EMH have been diagnosed by FNA. Nodular EMH can be found rarely in other organs as in the liver.

Abstract
Iron has been implicated to play an important role in several models of tissue injury, including myoglobinuric acute renal failure. In this model, myoglobin released from the injured muscle is generally accepted as a source of iron. In the present study we measured the bleomycin-detectable iron (iron capable of catalyzing free radical reactions) in the kidneys and examined the role of cytochrome P-450 as a source of catalytic iron in glycerol-induced model of myoglobinuric acute renal failure. Rats were injected with 50% glycerol (8 ml/kg) i.m. after overnight water deprivation and sacrificed 24 hours later. There was a marked and a specific increase in the bleomycin-detectable iron content accompanied by a marked decrease in the cytochrome P-450 content in the kidneys of glycerol treated rats. We then examined the effects of two different cytochrome P-450 inhibitors, cimetidine (with ranitidine as a control) and piperonyl butoxide. Cimetidine, but not ranitidine, significantly prevented the increase of bleomycin-detectable iron in the kidneys of glycerol-treated rats. The loss of cytochrome P-450 content was substantially blocked by both inhibitors, cimetidine and piperonyl butoxide, but not by ranitidine. Both the inhibitors of cytochrome P-450 provided functional (as measured by BUN and creatinine) and histological protection against glycerol-induced acute renal failure. Our data thus demonstrate a marked increase in bleomycin-detectable iron in the kidneys of glycerol-treated rats. Our data also indicate that inhibitors of cytochrome P-450 provide protection against glycerol-induced acute renal failure and that cytochrome P-450 may be a significant source of this iron in this model of acute renal failure.

Abstract
OBJECTIVE To determine the relative frequency of Blastomyces dermatitidis among other microorganisms in bronchoalveolar lavage (BAL) specimens. STUDY DESIGN The study group consisted of 208 BAL specimens received from 192 patients from March 1988 to August 1993. RESULTS Forty-seven specimens from 42 patients were positive for pathogenic microorganisms, and 2 other specimens were diagnostic of malignancy. Pneumocystis carinii (23 specimens) was the most common microorganism found in the specimens. Candida spp (10 specimens) was the second most common microorganism, and B dermatitidis (5 specimens) was the third. Cryptococcus neoformans (3 patients), Histoplasma capsulatum (2 patients) and Conidiobolus coronatus (1 patient) were the other fungi detected in BAL. Acid-fast bacilli, cytomegalovirus and herpes simplex virus were also found (1 patient each). Several patients had more than one organism. CONCLUSION B dermatitidis was the third most common microorganism found in BAL specimens at our hospital.

Abstract
Accurate staging as per National Wilms' Tumor Study (NWTS) criteria is essential for therapy of Wilms' tumor. We report a unique case of a 9-mo-old white male in whom the diagnosis based upon clinical, radiological, surgical, and initial histopathologic findings was Stage I Wilms' tumor without regard to a positive cytologic examination of a small amount (5 ml) of chylous ascitic fluid obtained intraoperatively. This problem was clarified later at the NWTS panel review when the deeper recuts of a renal hilar lymph node revealed a single cluster of Wilms' tumor cells in capsular sinus, resulting in upstaging of tumor to Stage III. The significance of these findings in relation to staging will be discussed.

Abstract
The extracranial spread of a primary intracranial tumor is an infrequent occurrence. The most common metastatic sites in order of frequency are bone, lymph nodes, and soft tissue. Analysis of the literature uncovered only two case reports of medulloblastoma that had metastasized to the breast. Both of these cases were diagnosed by open surgical biopsies. We present a case of medulloblastoma metastatic to the breast which was diagnosed by fine-needle aspiration biopsy. This diagnosis was subsequently confirmed by a tru-cut surgical biopsy and was further supported by immunohistochemical studies.

Abstract
Occasionally, insect bites producing systemic complications are the reason for admission to paediatric intensive care. We report an interesting case of multiple bee stings in a 2-year-old boy. The boy, who was stung more than 200 times by honey bees, had a severely deranged coagulation profile with marked elevation of the hepatic enzymes. This complication has not been reported to date. Prompt intensive supportive care led to the child's total recovery.

Abstract
Out of 640 suspected cases of neonatal septicaemia studied, bacteraemia was detected in 255 (40 per cent) of the infants. Gram negative organisms were predominant (56 per cent) with Pseudomonas, Citrobacter, and Klebsiella as the commonest pathogens. Among the Gram positive organisms both Staphylococcus aureus and Staphylococcus epidermidis were equally prevalent. Staphylococci were mainly responsible for early onset infections, whereas Salmonella typhimurium and Pseudomonas were the main organisms in late onset infections. Group B streptococcal infection was not encountered in this part of the country.

Abstract
Painful restricted movements of the extremities, hyperpigmentation over swollen joints, and a sclerema-like feel to the skin with increased serum triglyceride was seen in a 5-month-old baby with postnatal CMV infection. In an infant with pseudoparalysis of the limbs, the possibility of CMV infection has to be considered.

Abstract
We examined the effect of a selenium-deficient diet on two experimental models of glomerular disease, the puromycin aminonucleoside (PAN)-induced nephrotic syndrome, a model of minimal change disease, and passive Heymann nephritis, a complement-dependent and neutrophil-independent model that resembles membranous nephropathy. The specific activity of selenium-dependent glutathione peroxidase was markedly reduced in the liver, the kidney cortex, and in glomeruli in weanling male Sprague-Dawley rats placed on a selenium-deficient diet for 6 wk compared with rats fed a selenium-replete diet, with no significant differences in the specific activities of superoxide dismutase or catalase. PAN-injected selenium-deficient rats had a marked and significantly greater proteinuria throughout the course of the experiment compared with PAN-injected selenium-replete rats with no significant histological differences. In the passive Heymann nephritis model induced by injecting anti-Fx1A immunoglobulin G, rats fed a selenium-deficient diet had significantly higher urinary protein (day 5: 91 +/- 16 mg/24 h, n = 10) compared with rats fed a selenium-replete diet (52 +/- 5 mg/24 h, n = 11) with no differences in the amount of antibody deposited in the kidney. The most likely explanation for the effect of a selenium-deficient diet is that selenium deficiency resulted in a marked reduction of glutathione peroxidase, thus indicating an important role of glutathione peroxidase in these models of glomerular injury.

Abstract
Estimation of proteinuria in children is cumbersome when a 24 h urine collection is needed. In the presence of a stable glomerular filtration rate, the ratio of urinary protein and creatinine should reflect the protein excretion. One hundred samples of urine (24 h and random samples) were collected from 50 children with nephrotic syndrome, 25 with nephrotic syndrome in remission and 25 normal children. The 24 h urine total protein and random urine protein-creatinine ratio were assessed on these samples. Linear regression analysis of the results showed excellent correlation between the values (r = 0.81, p less than 0.001). A random urine protein-creatinine ratio of greater than 3.5 correlated with massive proteinuria, while a ratio less than 0.2 was suggestive of physiological values. The sensitivity, specificity, positive and negative predictive values of the protein-creatinine ratio in massive proteinuria were very high. We conclude that the random urine protein-creatinine ratio can be used reliably to assess the degree of proteinuria in children.

Abstract
Fourteen neonates were diagnosed to have Citrobacter sepsis during 1986-89, representing 4.6% of all cases with bacteriologically proven sepsis. Most of these infants were low birth weight (mean 2046 gm, +/- 750) and preterm (mean 34.8 weeks, +/- 3.8). Mean age at onset of sepsis was five days. In 10 cases the hematological profile was suggestive of sepsis. Infants had clinical evidence of multisystem infection; 2 with septic arthritis and 3 meningitis. The case fatality rate was 61%. Resistance to antibiotics was frequent. Citrobacter species were also cultured from other sites: umbilical stumps, eye swabs, urine, skin pustules and umbilical catheter tips. The epidemiological features and virulence of this organism call for vigilance and strict control measures.

Abstract
Ewing's sarcoma, an uncommon malignant neoplasm of bone, represents about 10% of all the malignant primary bone tumors. The assumption that subclinical metastases are already present in patients with apparently localized tumor indicates the need for systemic therapy as an integral part of primary treatment. The usual sites of metastases are the lungs and skeletal system. Central nervous system (CNS) involvement is rare and is usually seen only in disseminated and fairly advanced disease. We report two patients in whom, after aggressive adjuvant chemotherapy, disease developed in the CNS without local recurrence. In one patient, meningeal involvement with malignant cells was identifiable in the cerebrospinal fluid; in the second patient, who presented with a space-occupying lesion, a diagnosis of arachnoid involvement was made histologically.

Abstract
Serum apolipoproteins A (Apo-A) and B (Apo-B) and lecithin: cholesterol acyl transferase (LCAT) activities and 24-hour urinary cholesterol levels were estimated in 25 nephrotic children before and during steroid treatment with 4 weeks of daily prednisolone followed by another 4 weeks of alternate-day prednisolone. The patients with untreated nephrotic syndrome (NS) showed significant decrease in serum Apo-A and LCAT activities associated with significant increase in serum Apo-B and urinary cholesterol levels compared to healthy controls (n = 25). Serum Apo-A levels correlated directly and Apo-B levels inversely with the serum albumin concentrations. After a transient elevation, the serum Apo-A level returned to control range by 8 weeks of treatment accompanied by a gradual increase in serum LCAT activity and decrease in urinary cholesterol excretion. Though, the serum Apo-B level was decreased with treatment, it was still significantly high compared to the controls.

Abstract
Fabry's disease is a rare, X-linked disorder of glycolipid metabolism that is usually recognized in men in the third and fourth decades of life. A heterozygous state in women has been documented, but reports about women who are affected are confined to isolated case reports and to rare small series. We report a case of a 42-year-old woman with persistent proteinuria who was found to have Fabry's disease. The characteristic lesion was readily seen using routine high-resolution light microscopy (HRLM) tissue sections without the need of multiple extra tissue sections and special stains. We discuss the correlation of clinical findings, fluorescent microscopy, HRLM, electron microscopy, and biochemical enzymatic studies in establishing the diagnosis.
