Does maternal nicotine exposure during gestation increase the injury severity of small intestine in the newborn rats subjected to experimental necrotizing enterocolitis.

BACKGROUND/PURPOSE: The aim of this study was to evaluate the effects of maternal nicotine exposure during gestation on injury severity of small intestine in the newborn rats subjected to hypoxia-reoxygenation and cold stress. METHODS: A total of 21 Sprague-Dawley pregnant rats were divided into 3 equal groups. The groups were labeled as group 1, control group; group 2, hypoxia-reoxygenation group; and group 3, nicotine-hypoxia-reoxygenation group. The rats of group 3 were exposed to nicotine via subcuticular injection for the last week of gestation (2 mg/kg/d). Newborn rats were collected immediately after birth to prevent suckling of maternal milk (40 rat pups in group 1, 43 rat pups in group 2, and 41 rat pups in group 3). Litters in groups 2 and 3 were stressed twice daily with asphyxia followed by cold (4 degrees C for 10 minutes) stress to induce hypoxic intestinal injury which is relevant to human necrotizing enterocolitis. Breathing 100% CO2 for 10 minutes in a chamber followed by 10-minute 100% O2 breathing was the asphyxia model repeated twice daily. After hypoxia-reoxygenation and cold stress, newborn rats were returned to their mother's cages. This protocol was repeated for the following 2 days, and the rat pups were decapitated on the third day. Using this protocol of asphyxia and cold stress, all of neonatal rats developed clinical and pathological signs of hypoxia-induced intestinal injury. The entire gastrointestinal tract was removed and examined macroscopically. A 2-cm section of distal ileum from each animal was taken for histopathological and biochemical examinations. Histological changes in ileal architecture were scored and graded from 1 to 5. The remaining intestinal tissues of the animals were used for lipid peroxidation analysis. RESULTS: Typical signs of hypoxia-induced intestinal injury were observed in the 2 experimental groups (groups 2 and 3) macroscopically. There were more grades 3 and 4 injuries in group 3 (P < .05). The malondialdehyde levels were elevated in groups 2 and 3 (P < .001). The malondialdehyde levels of the group 3 were also significantly higher than group 2 (P < .01). CONCLUSIONS: Maternal nicotine exposure during gestation results in higher grade histological injury in newborn rats subjected to hypoxia-reoxygenation and cold stress.

Eyelid involvement in acanthosis nigricans: the importance of systemic screening.

A 53-year-old man presented with thickening and hyperpigmentation of the eyelids. After the diagnosis of acanthosis nigricans was made, further investigation of a possible underlying disorder, including biochemical and instrumental examinations, indicated the presence of glucose intolerance, which had been diagnosed 3 years after the clinical appearance of acanthosis nigricans. Eyelid involvement in acanthosis nigricans is rare. Ophthalmologists should be aware of the possibility that acanthosis nigricans can exist in the periocular area and perform a systemic assessment of the patient for the presence of an underlying condition.

Lipoid proteinosis: an unusual presentation with verruca vulgaris.

Lipoid proteinosis (LP) is a very rare, autosomally recessive, inherited disease. It is also known as Urbach Wiethe disease or Hyalinosis cutis et mucosa. LP usually runs a benign, stable, and slowly progressing course. We present one LP case with additional unusual dermatologic involvement; verruca vulgaris was superimposed on papular lesions of LP. To our knowledge, this case is the first and only one described in the literature. In this presentation, we discuss the possibility of predisposition to Human Papilloma Virus (HPV) infections in LP.

The effect of zinc therapy on damaged testis in pre-pubertal rats.

This experimental study was instituted to evaluate whether or not there is an effect of zinc aspartate administration on injured testes. Sixty prepubertal male Sprague-Dawley rats (weighing 180-240 g) were divided into six equal groups each containing ten rats. Group I was the control group. Rats in group II and group III which were blunt testicular trauma groups were subjected to right blunt testicular trauma to rupture the tunica albuginea. Just after this, animals in group III were given 30 mg/kg zinc aspartate intraperitoneally, and this treatment was continued for 30 days at a dose of 10 mg/kg per day. Animals in group IV and group V which were thermal injury groups were subjected to right thermal testicular injury with injection of boiling normal saline. After that, animals in group V were also treated with zinc aspartate as described in group III. Group VI was used as a sham group. After 30 days, both testes were removed and examined. Damage in ipsilateral testes was evaluated with histological scoring methods. Contralateral testes were evaluated with measurement of tubular diameter and percentage of spermatogenesis histologically. Ipsilateral testes from non-treated groups had much greater histological injury than treated groups ( p>0.05). Additionally, contralateral testes had no evidence of injury. As a consequence, after acute testicular injury that takes form in a variety of ways, immediate administration of zinc aspartate and its continuation for some period may prevent the progression of the injury and improves the healing process.

Tuberculosis of the knee in a child.

The diagnosis for skeletal tuberculosis is often overlooked. We report a 9-year-old patient with a history of 2 years of swollen joint, with a diagnosis of tuberculosis of the knee with involvement of the proximal tibial epiphysis, and treated surgically and with anti-tuberculosis drug therapy.

Pityriasis rosea-like eruption due to pneumococcal vaccine in a child with nephrotic syndrome.

A pityriasis rosea-like eruption can occur as a consequence of treatments with gold compounds and captopril. It has rarely been reported to have an association with vaccinations such as smallpox, BCG, hepatitis B, and diphtheria toxoid. It has not previously been documented to develop after pneumococcal vaccination. We report a case of pityriasis rosea-like eruption that developed following pneumococcal vaccination in a child with nephrotic syndrome.

Pai syndrome: an adult patient with bifid nose and frontal hairline marker.

OBJECTIVE: A 17-year-old previously unreported patient with Pai syndrome is described. The boy had median cleft of upper lip, a polypoid skin mass over the columella, a minimal cleft of the upper central incisors, frontal alopecia of the anterior hairline, and bifid nose. Magnetic resonance imaging showed pericallosal lipoma. No mental retardation was present, and a chromosomal study showed normal male 46, XY karyotype.

Cutaneous anthrax of the hand and its reconstruction with a reverse-flow radial forearm flap.

Bacillus anthracis infection can lead to necrosis in tissues and may manifest as a fatal disease in human beings. The authors present a patient with a large area of skin necrosis on the dorsum of the hand that was reconstructed with a reverse flow-through radial forearm flap, and they discuss the relevant literature. To the authors' knowledge, this is the first published report of such extensive necrosis resulting from anthrax limited to the extensor retinaculum of the hand.

Psoriasis vulgaris and Poland's syndrome in the same patient.

Most common anomalies associated with Poland's syndrome are in the chest wall. This type of anomaly causes important psychological distress, especially in adolescent girls. A 19-year-old female with Poland's syndrome having psoriatic plaques on her trunk, knees, and elbows is reported in this paper. Such an association of Poland's syndrome with psoriasis has not been described previously.
