Laparoscopic nephrectomy for pyonephrosis during pregnancy: case report and review of the literature

The maternal and fetal complications of pyonephrosis during pregnancy can be devastating, thus the call for urgent but safe intervention. Laparoscopic nephrectomy has been used safely and effectively in nonpregnant patients with pyonephrotic kidney. We report on a case of a 28-year-old pregnant woman with pyonephrotic kidney that we believe to be the first such case managed by transperitoneal laparoscopic nephrectomy. A review of the reported cases of laparoscopic nephrectomy for different indications and by different approaches during pregnancy is also presented.     

Treatment of promyelocytic leukemia during pregnancy. A case report and review of the literature

In spite of the fact that acute promyelocytic leukemia during pregnancy is rare and that there is little precedent in the literature for treatment with combined chemotherapeutic agents, the rate of success with current chemotherapeutic regimens is very encouraging. Judging from previous reports and our own experience, it is possible to give combination chemotherapy to pregnant women with AML/APL with the result that mother and infant survive, whereby the incidence of complication is within an acceptable range. No comprehensive studies on life-time teratogenic or carcinogenic effects are available at present.     

Prosthetic heart valve thrombosis, anticoagulation and pregnancy: a case report and review of literature

In pregnant patients with a prosthetic heart valve (PHV), anticoagulation with warfarin is associated with embryopathy, foetal loss early in pregnancy and maternal bleeding complications in the delivery period. The optimal anticoagulation strategy in the pre-pregnancy period and during pregnancy itself is controversial and a matter of debate. We describe a patient with PHV in the pre-pregnancy period and in a subsequent pregnancy. The optimal anticoagulation treatment strategy in women in their reproductive years with mechanical valve thrombosis is discussed. (Neth Heart J 2007;15: 306-9).     

Chondrosarcoma of the trachea. A case report and literature review

The cytologic presentation of a case of chondrosarcoma of the trachea in a 72-year-old man is described. A mass detected on routine chest roentgenogram and defined by CT scan was used to make a touch imprint smear during partial tumor resection. The cytologic findings included round or polygonal cells with occasional binucleation, round hyperchromatic nuclei and prominent nucleoli, present in an amorphous pink-violet or light-blue background containing fragments of chondroid tissue. The histopathology was interpreted as a low-grade chondrosarcoma. Cartilaginous tumors of the trachea should be considered in the differential diagnosis of upper airway obstruction.     

Human pentastomiasis in China: case report and literature review

A 13-yr-old boy was admitted because of persistent fever, abdominal pain and diarrhea for 3 mo. Abdomen CT revealed hepatomegaly and multiple nodular low-density pathological changes. At laparotomy considerable yellow and turbid ascites were seen in the abdominal cavity and miliary nodules were noted on the surface of the omentum majus, liver, and small intestine wall. Histological examination revealed parenchymal tubercles containing several worms. Pathological diagnosis was parasitic granuloma. These parasites were identified as Porocephalus taiwana sp.nov. The patient made an uneventful recovery after therapy and was discharged. Moreover, another 17 cases of human pentastomiasis reported from China were reviewed. Human pentastomiasis is an extremely rare disease and this is only the second case of human Porocephalus taiwana sp.nov infection. Pentastomiasis should be considered in differential diagnosis of patients with a history of abdominal symptoms and eating of poorly-cooked snakes.     

Clostridial abomasitis in calves: case report and review of the literature

Infections by Clostridium perfringens type A are perhaps the most common causes of clostridial hemorrhagic enteritis in neonatal ruminants. Affected calves exhibit tympany, hemorrhagic abomasitis, and abomasal ulceration. Gram-positive bacilli are often found on affected mucosa and in submucosa. Aspects of etiology beyond the infecting organism are little understood, but probably include dietary issues, perhaps relating to overfeeding, feeding of barely thawed or contaminated colostrum, or conditions which effect decreased gut motility. Fatal hemorrhagic enteritis in a cloned gaur calf is illustrative of the syndrome. The calf developed pasty yellow and bloody diarrhea, and the abdomen became distended and painful. In spite of intensive therapy, the calf died approximately 48 h after birth. At necropsy, the distended abomasum contained clotted milk and bloody fluid, and the abomasal and omasal walls were thickened and hemorrhagic. The proximal duodenum was hemorrhagic and emphysematous, and microscopic examination revealed Gram-positive rods in association with acute, necrotizing, hemorrhagic mucosal inflammation. Isolates of C. perfringens from this calf were PCR positive for cpb2, the gene encoding beta2 toxin. This finding is of unknown significance; only 14.3% (8/56) of isolates from other calves with the syndrome have been cpb2 positive, and only 50% of cpb2 positive bovine isolates express CPB2. The most prominent needs to further our understanding of this problem are consistent experimental reproduction of the disease, elucidation of virulence attributes, and development and application of prevention and control strategies.     

Cutaneous ciliated cyst: case report and literature review

An 18-year-old girl had a cyst excised from the left buttock in 1988. The cyst was diagnosed to be a cutaneous ciliated cyst, since histologic examination using special stains demonstrated its lining to be similar to fallopian tube epithelium. Only 20 such cases have been published to date, and this report is probably the first case in the plastic surgical literature, to the best of our knowledge.     

Rhinosporidiosis in Egypt: A case report and review of literature

Rhinosporidiosis is an infection caused by Rhinosporidium seeberi that frequently presents as a polypoidal nasal lesions. Here, we report the first indigenous case of tumoral rhinosporidiosis in Egypt. In this case, a 25-year-old male patient from a rural background of Assuit City presented with epistaxis and a nasal polyp. The patient had not traveled abroad. The diagnosis was established on the morphological basis by the identification of 5- to 10-m endospores and 50- to 1000-m sporangia. The clinicopathological and immunologic features were discussed and the literature was reviewed. To the best of our knowledge this is the first case of this disease to be reported in Egypt in the human literature.     

Ring chromosome 11. A case report and review of the literature

A female infant with severe growth-weight retardation and with a ring chromosome 11, associated with trisomy X in 15% of metaphases, has been reported. A literature review of cases of r(11) shows that the clinical features of these patients, although showing different frequencies, are similar to those of the del(11q) syndrome. It has been suggested that the variability of the mental retardation in r(11) patients is attributable to the unstability of the ring and to the different break points in these two chromosomal rearrangements. The origin of the r(11) was also addressed by studying fragile sites of the parents at 11p15 and 11q25.     

Ganglions of the temporomandibular joint: case report and review of literature

We present the third reported case of a ganglion cyst arising from the temporomandibular joint. Like the previous two cases, this lesion occurred in a woman over the age of 40. Unlike the lesions in previous reports, the cyst in our patient was not associated with pain or tenderness, making the diagnosis of parotid tumor more likely. Nevertheless, the case serves to illustrate the need for including ganglion in the differential diagnosis of well-encapsulated preauricular masses in the region of the temporomandibular joint.

Primary cutaneous adenoid cystic carcinoma: a case report and review of the literature.

A case of adenoid cystic carcinoma of the ear in a 67-year-old man is presented along with a review of the literature. Adenoid cystic carcinoma most commonly arises in the salivary glands. Primary cutaneous adenoid cystic carcinoma occurs principally in the scalp and chest. Perineural invasion is seen in at least half the cases and is associated with an increased recurrence rate. Treatment consists of wide local resection with tumor-free margins. Just over half the patients will develop recurrence, with long tumor-free intervals necessitating long-term follow-up. Distant metastases are rarely seen. Radiation therapy is not curative and should be reserved for palliation.

Lymphoplasmacytic sclerosing pancreato-cholangitis: a case report and review of the literature

Autoimmune pancreatitis is a rare but important cause of pancreatitis that is becoming increasingly recognized in the West. Lymphoplasmacytic sclerosing pancreatitis (LPSP) is a benign form of chronic pancreatitis characterized clinically by infrequent attacks of abdominal pain, jaundice, and weight loss, and pathologically by focal or diffuse chronic or lymphoplasmacytic inflammatory infiltrates centered around pancreatic ducts and ductules, accompanied by obliterative phlebitis, acinar atrophy, and interstitial fibrosis. It has been described alone or as a part of the spectrum of autoimmune gallbladder and biliary tract disease, with clinical, radiological, and pathological overlap reported with primary sclerosing cholangitis. It has been described as "primary sclerosing pancreatitis," "sclerosing cholangitis," "non-alcoholic duct destructive chronic pancreatitis," and "autoimmune pancreatitis." We report a case of LPSP that mimicked pancreatic adenocarcinoma and was subsequently treated with a pylorus-preserving Whipple procedure. This may point towards a primary biliary autoimmune process involving the pancreatic duct, causing a benign form of chronic pancreatitis that may be difficult to characterize pre-operatively to avoid surgery. This case typifies the growing awareness of this relatively recently characterized clinical entity, its similar presentation to pancreatic carcinoma, and the importance for LPSP to be included in the differential diagnosis of pancreaticobiliary disease. Finally, we review the literature.     

Ectopic ACTH syndrome due to pheochromocytoma: case report and review of the literature.

A 51-year-old female was diagnosed preoperatively to have a pheochromocytoma producing ACTH. This diagnosis was based upon her paroxysmal hypertension, hyperpigmentation, and hypokalemia. Elevated levels of serum and urine corticosteroids, plasma ACTH, urinary VMA, and catecholamines fell after a right adrenal pheochromocytoma was removed. Subsequently this tumor was found to have a high content of ACTH. Review of the literature indicates a mortality rate of 57% for this syndrome. Proper preoperative recognition and management can result in total cure.
