Sinus histiocytosis with massive lymphadenopathy.

Sinus Histiocytosis with Massive Lymphadenopathy is a very rare condition often presenting as neck swelling of unknown etiology. The disease involves extranodal sites in 20-30 percent of cases and histologically characterized by emperiopolesis, non-cohesive and non-epitheloid histocytes with abundant eosinphilic cytoplasm. An ideal treatment is yet to be established but here we present a short series of chemotherapy with alternating ABVD and COPD cycles giving satisfactory results.

Mammary tuberculosis: analysis of thirty-eight patients.

Thirty-eight patients with mammary gland tuberculosis were evaluated over a 5-year period presenting to the surgical unit of our institution. Unilateral involvement of the breast in a woman presenting at an average age of 29 years was the commonest observation. A lump in the breast with or without discharging sinuses was the most common clinical presentation.

SUN1 interacts with nuclear lamin A and cytoplasmic nesprins to provide a physical connection between the nuclear lamina and the cytoskeleton.

Nuclear migration and positioning within cells are critical for many developmental processes and are governed by the cytoskeletal network. Although mechanisms of nuclear-cytoskeletal attachment are unclear, growing evidence links a novel family of nuclear envelope (NE) proteins that share a conserved C-terminal SUN (Sad1/UNC-84 homology) domain. Analysis of Caenorhabditis elegans mutants has implicated UNC-84 in actin-mediated nuclear positioning by regulating NE anchoring of a giant actin-binding protein, ANC-1.

Primary osteosarcoma of the skull.

Primary osteogenic sarcoma of the skull is an exceedingly rare condition. An adult male patient is described, who had a painless swelling in the right forehead that had rapidly enlarged in the previous 6 months. Radiological investigations showed a large destructive mass lesion involving the right side of the frontal bone with extension into the frontal sinus, causing marked extradural compression of brain parenchyma.

Ultrasound and colour Doppler sonography in acute osteomyelitis in children.

Early diagnosis of osteomyelitis is of paramount importance to avoid irreversible sequelae. This often requires a multimodal approach. The purpose of the present study was primarily to evaluate how ultrasound might be useful in early diagnosis of osteomyelitis in the paediatric age group.

Congenital macrodactyly: a clinical study.

Congenital macrodactyly is a rare congenital malformation characterised by progressive enlargement of all mesenchymal elements of a digit. The present study is an attempt to draw the attention towards the similarities and differences between macrodactyly of the hand and foot. Radiographical, operative findings and histopathological examination of five cases are included in the present study.

Synchronous germinomas in the pineal and suprasellar region.

Synchronous primary intracranial germ cell tumors are rare. Only 5-10% of all germ cell tumors are found as synchronous lesion in pineal and suprasellar region. They are also known by the entity "double mid-line atypical teratoma".

Effects of pentoxyfylline on mesenteric lymph node T-cells in a rat model of thermal injury.

Cutaneous burn injury-induced T lymphocyte suppression is a well-known phenomenon. In this study, we evaluated the effect of treatment of burn rats with pentoxifylline (PTX) on the burn-induced suppression of T lymphocytes. Anesthetized rats were subjected to 30% total body surface area burn by exposing skin to 95 degrees C water for 10 s.

Enteral nutritional supplementation prevents mesenteric lymph node T-cell suppression in burn injury.

Objective: To determine the effects of an immune-enhancing diet supplemented with glutamine, arginine, fish oil, and dietary nucleotides on mesenteric lymph node T-cell functional disturbances encountered after burn injury in rats.

Design: A prospective animal study.

Setting: University medical center research laboratory.

Iniencephaly.

Iniencephaly is a rare congenital anomaly which is a type of neural tube defect. Babies with iniencephaly are almost always still born but exceptionally live born cases are reported. This article reports a case of a live born iniencephalic baby who died about 15 minutes after birth.

Enterococcus faecalis exacerbates burn injury-induced host responses in rats.

Pathophysiology of burn injury with complications of gram-positive infections is not well characterized. We have developed an in vivo rat model to study the effects of burn injury along with intra-abdominal inoculation of Enterococcus faecalis. We hypothesized that although burn injury or E.

Role of NFAT and AP-1 in PGE2-mediated T cell suppression in burn injury.

PGE2 is known to suppress T cell proliferation and IL-2 production in many inflammatory conditions. Previous studies from our laboratory have shown that such suppression of T cell proliferation in burn and sepsis could result from alteration in T cell activation signaling molecule p59fyn. In this study, we examined the role of downstream signaling molecules NFAT and AP-1 in PGE2-mediated suppression of T cell in burn injury.

PGE2 suppresses intestinal T cell function in thermal injury: a cause of enhanced bacterial translocation.

Increased gut bacterial translocation in burn and trauma patients has been demonstrated in a number of previous studies, however, the mechanism for such an increased gut bacterial translocation in injured patients remains poorly understood. Utilizing a rat model of burn injury, in the present study we examined the role of intestinal immune defense by analyzing the T cell functions. We investigated if intestinal T cells dysfunction contributes to bacterial translocation after burn injury.

Isolation of Bifidobacteria infantis and its antagonistic activity against ETEC 0157 and Salmonella typhimurium S-285 in weaning foods.

Probiotic organism Bifidobacteria was isolated from the faeces of breast-fed infants at Universiti Putra Malaysia. Trypticase phytone peptone yeast extract agar (TPY) was used as a selective media for the isolation. Morphological examination of the isolates indicated that Bifidobacteria was Gram-positive rods in nature, curved with characteristics of V and Y shapes.

Positive response to sodium antimony gluconate administration in visceral leishmaniasis seropositive patients.

In a prospective study conducted in Mymensingh district of Bangladesh, 1, 273 patients were assessed for the presence of visceral leishmaniasis (VL). Sodium antimony gluconate (SAG) was successfully administered to 715 patients with parasitologically confirmed infection. In the remaining 558, although there was clinical indication of VL, Leishmania donovani parasites could not be demonstrated.
