Osteoma cutis in pseudohypoparathyroidism.

Osteoma cutis is the formation of normal bone in the skin. Primary osteoma cutis occurs de novo, whereas the secondary type develops in association with the underlying inflammatory, tumorous or traumatic conditions. Primary osteoma cutis is also associated with Albright's hereditary osteodystrophy (AHO), which can include hypocalcaemic-type pseudohypoparathyroidism (also known as pseudohypoparathyroidism type Ia) or normocalcaemic-type pseudohypoparathyroidism (also known as pseudopseudohypoparathyroidism). We describe a case of osteoma cutis in a 7-year-old boy who had cutaneous, biochemical and phenotypic features of pseudohypoparathyroidism type Ia and AHO.

Familial pachydermoperiostosis in association with protein-losing enteropathy.

In this report we describe a rare association of pachydermoperiostosis with protein-losing enteropathy (PLE) in a family of three brothers. The first brother had the complete form of pachydermoperiostosis along with PLE. The second brother had the 'forme fruste' of pachydermoperiostosis, with minimal skin changes, bony abnormalities and PLE, which was due to intestinal lymphangiectasia. The third brother had an incomplete form of pachydermoperiostosis without evidence of PLE. To our knowledge, the association of pachydermoperiostosis with PLE due to intestinal lymphangiectasia has not been reported previously.

Differential representations of memory T cell subsets are characteristic of polarized immunity in leprosy and atopic diseases.

We identified functionally polarized subsets of CD4 memory T cells on the basis of the expression of CD11a, CD45RA and CD62L. Within the several phenotypically distinct subsets of CD4 memory cells are two that, upon stimulation, produce primarily IL-4 (MT(2), CD45RA(-)CD62L(+)CD11a(dim)) or primarily IFN-gamma (MT(1), CD45RA(-)CD62L(-)CD11a(bright)). In addition, four other phenotypically distinct subsets of CD4 cells have unique cytokine profiles. To determine the clinical relevance of the representation of these cell types, we analyzed blood from patients with the chronic diseases leprosy and atopy. These diseases are characterized as immunologically polarized, since T cell responses in affected individuals are often strongly biased towards T(h)1 (dominated by IFN-gamma production) or T(h)2 (IL-4 production). We show here that this polarization reflects homeostatic or differentiation mechanisms affecting the representation of the functionally distinct subsets of memory CD4 T cells, MT(1) and MT(2). Significantly, the representation of the MT(1) and MT(2) subsets differs dramatically between subjects with tuberculoid leprosy (a T(h)1 disease), or lepromatous leprosy or atopic disease (T(h)2 diseases). However, there was no difference in the cytokine profiles of these or any of the other finely resolved CD4 subsets, when compared between individuals across all disease states. Thus, it is the representation of these subsets in peripheral blood that is diagnostic of the polarized state of the immune system.

The frequency of sexual dysfunctions in patients attending a sex therapy clinic in north India.

Analyzed data on 1000 consecutive patients with sexual disorders attending the psychosexual clinic at the All India Institute of Medical Sciences. The majority of patients were educated males between 21 and 30 years of age, belonging to the middle class. There was a slight preponderance of married patients. Fifty-two percent of patients had premarital or extramarital sexual contact; less than 5% had had homosexual contact; 10% had no sexual contact. Most patients had more than one complaint. Premature ejaculation (77.6%) and nocturnal emission (71.3%) were the most frequent problems followed by a feeling of guilt about masturbation (33.4%) and small size of the penis (30%). Erectile dysfunction was a complaint of 23.6%. Excessive worry about nocturnal emission, abnormal sensations in the genitals, and venereophobia was reported in 19.5, 13.6, and 13% of patients, respectively. Only 36 female patients attended the clinic with their spouses.

Post-kala-azar dermal leishmaniasis--an unusual presentation.

Post-kala-azar dermal leishmaniasis can present as hypopigmented macules, erythematous to skin-coloured papules, nodules and photosensitive butterfly erythema on the face. We present a patient with disseminated annular lesions of post-kala-azar dermal leishamaniasis. The patient was treated with daily intravenous injections of sodium antimony gluconate for 120 days at a dose of 20 mg/kg body weight with complete clearance of lesions.

Toxic epidermal necrolysis.

BACKGROUND: Most studies on drug-induced toxic epidermal necrolysis (TEN) report a high mortality rate. This has been attributed partly to the use of corticosteroids for its treatment. However, we consider corticosteroids to be the sheet anchor for saving the patients having TEN. MATERIALS AND METHODS: Our approach to the treatment of this disease consists of administering a relatively high dose of corticosteroids to control the reaction at the earliest possible time and then withdrawing corticosteroids at the fastest possible rate. RESULTS: As illustrated by the five case reports, the reaction is controlled within 24 to 48 hours and the corticosteroids are withdrawn within the next 7 to 10 days. During this period, the skin also shows almost complete healing. With the confidence gained with this approach, we undertake the provocation test as a rule in every patient to find the actual drug responsible for the reaction.. CONCLUSIONS: Corticosteroids used in an appropriate dosage schedule constitute an important component of the treatment for TEN to ensure early recovery.
