Case Report: Lepromatous Leprosy Masquerading as Acute Suppurative Lymphadenitis.

Leprosy is a chronic cutaneous infection. It is usually characterized by thickened nerves and maculo-anesthetic patches. Leprosy often has an unusual presentation, which is a diagnostic challenge. In this case report, we present a case of an elderly male who presented with fever and chronic pus-draining axillary, cervical, and inguinal lymph nodes. He also had a weak left foot for the previous 5 months. During his hospital stay, he developed additional papular lesions over his extremities. We performed fine needle aspiration from the lymph nodes and skin biopsy, which were suggestive of lepromatous leprosy. We initiated him on antileprosy medication. On follow-up, he was responsive to therapy. Although skin and nerve involvement in leprosy is common, this case had an atypical presentation of discharging lymph nodes.

A pilot study to determine Neisseria gonorrhoeae-Chlamydia trachomatis coinfection rates in symptomatic patients attending STI Clinics, New Delhi, India.

BACKGROUND: Neisseria gonorrhoeae and Chlamydia trachomatis are the two most prevalent bacterial sexually transmitted infections. For over two decades, treatment guidelines have recommended empirical co-treatment for N.gonorrhoeae and C.trachomatis as symptoms overlap and co-infection is common. Studies from India estimating the same are limited and mostly based on conventional techniques. AIM AND OBJECTIVE: The aim of this study was to determine the frequency of N.gonorrhoeae and C.trachomatis coinfection using nucleic acid amplification tests. Further, we assessed the utility of pus cell estimation in Gram stained smears as a screening tool for inclusion of samples for molecular diagnosis. METHODS: This was a prospective study conducted at two tertiary care hospitals; 100 patients (55 females and 45 males) with genitourinary discharge attending STI clinics were recruited, and endocervical or urethral swabs were collected. PCRs for N.gonorrhoeae and C.trachomatis were put up. In addition, microscopy and culture for gonococcus was performed followed by antimicrobial susceptibility testing. Statistical analysis was performed using the SPSS 16 software. RESULTS: N.gonorrhoeae infection was more common than C.trachomatis. A total of 14 patients were positive by PCR (9 males and 5 females) for gonococcus. However, culture was positive only in 8 male patients. PCR for C.trachomatis was positive in 9 (4 males and 5 females) and the co-infection rate was 5%. The sensitivity and negative predictive value of pus cell estimation was 100% for males and 64% and 94.6% respectively for females. All isolates were susceptible to extended spectrum cephalosporins and azithromycin. LIMITATION: The sample size of the study was small. CONCLUSION: Frequency of N.gonorrhoeae/C.trachomatis coinfection in symptomatic STI patients is low. Coinfection is considerably overestimated and necessary confirmation of etiological diagnosis could reduce widespread empirical administration of broad-spectrum antibiotics.

Afectación cutánea en las micosis profundas: una revisión de la literatura. Parte 1: micosis subcutáneas / Cutaneous involvement in the deep mycoses: a literature review. Part I-subcutaneous mycoses

Las micosis profundas son infecciones poco frecuentes en nuestro medio. Se presentan principalmente en pacientes inmunodeprimidos o en regiones de climas tropicales, que abarcan las micosis subcutáneas y las micosis sistémicas. Las micosis subcutáneas o por implantación siempre producen signos de afectación cutánea. En la primera parte de esta revisión se realizará una revisión de las principales micosis subcutáneas: esporotricosis, cromoblastomicosis, micetomas, feohifomicosis, hialohifomicosis y lacaziosis. Reconocer y tratar estas micosis subcutáneas de forma precoz es importante, ya que a menudo están asociadas a una alta morbilidad

The deep mycoses are uncommon in our setting. These fungal infections occur mainly in immunosuppressed patients or in tropical climates, and include subcutaneous infections and systemic infections. The skin is always involved in the former. In the first part of this review, we describe the main subcutaneous mycoses: sporotrichosis, chromoblastomycosis, mycetoma, phaeohyphomycosis, hyalohyphomycosis, and lacaziosis. Early recognition and treatment is important, as these infections are frequently associated with high morbidity

Bacteriological study of pus isolates from neuropathic plantar ulcers associated with acute inflammatory phase.

In this retrospective study, sensitivity of organisms cultured from ulcers of leprosy patients without and with diabetes mellitus, diabetic patients without leprosy and patients with ulcers from other causes was examined. The profile of organisms grown from these groups of patients did not differ significantly. However, there was a high prevalence of organisms like Proteus, E. coli and Enterococcus in the ulcers of leprosy patients indicating faecal contamination of the ulcers. Co-trimaxazole and tetracycline were of little value in the treatment of these ulcers. We therefore recommend that in situations where there is no culture facility, the patients be started on a course of penicillin and gentamycin. If these antibiotics fail, it would be necessary to use more advanced antibiotics like norfloxacin, amikacin and ciprofloxacin.

Is fine needle aspiration cytology a useful tool for the diagnosis of tuberculous lymphadenitis?

OBJECTIVE: To study the role of fine needle aspiration cytology (FNAC) in the diagnosis of tuberculous lymphadenitis and find a place for FNAC as laboratory diagnostic method in tuberculosis (TB) control programmes. DESIGN: Prospective laboratory study. METHOD: Duplicate smears from 127 lymph node aspiration were prepared. Both slides were air-dried. Giemsa stain for cytological examination and Ziehl-Neelsen stain for demonstration of acid fast bacillus(AFB) were used and examined by a pathologist and laboratory technologist respectively. SETTING: Tigrai Regional Health Research and Laboratory Centre which is the only unit with microbiological and cytopathological service in the region. SUBJECTS: Patients with one or more enlarged lymph nodes who were sent for FNAC were included. RESULTS: The AFB positivity among the cytologically diagnosed cases of TB lymphadenitis was 56.77%. If we had used culture media for Mycobacterium spp, the positivity would have probably been higher. The positivity rate varied depending on the type of the aspirate. Caseous aspirate showed a higher positivity rate of 60.47% whereas no AFBs were detected in haemorrhagic aspirates. CONCLUSION: This study has demonstrated the usefulness of FNAC in the diagnosis of TB lymphadenitis and the national TB and leprosy control programmes should encompass FNAC as a diagnostic means instead of biopsy which is more invasive and costly.

Calcification of peripheral nerves in leprosy.

A study conducted in 74 TT/TB patients, with gross thickening of nerves together with nerve abscess, showed calcification in 8 patients. Calcification was most common in the ulnar nerve followed by the lateral popliteal nerve. All eight patients were males with significantly longer duration of illness before start of treatment. Patients with late onset of nerve abscess were found to be more prone to calcium deposition in the nerves. Caseous pus of the abscess had high lipid content with raised cholesterol and cholesterol ester ratio to total lipids suggesting a dystrophic nature of calcification.

Importance of group G streptococci in human pyogenic infections.

Streptococci that belong to groups other than A are involved in a variety of human infections. In the present study, we report the pyogenic infections associated with group G streptococci (GGS), observed at the Christian Medical College Hospital, Vellore, Tamil Nadu, India. Of 2314 beta-haemolytic streptococci isolated from 31,857 pus specimens processed during the period 1975-1986, GGS accounted for 338 (14.6%). Twelve of these were grown in pure culture. The clinical conditions associated with them included pyogenic arthritis, osteomyelitis, paravertebral sinus and an abdominal burst. Clinical analysis of 99 of 125 patients with GGS, grown in mixture with another organism or skin contaminants, showed that 59% of them were from surgical wound infections, diabetic lesions or wound infections in leprosy patients. Surgical management and antibiotic treatment resulted in full recovery of these clinical conditions.
